Specification

Description:Field of the Invention


The present disclosure generally relates to construction automation systems. Further, the present disclosure particularly relates to an automated rebar tying apparatus for reinforcement installation.
Background
The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
The present disclosure generally relates to automated systems for rebar tying used in reinforcement installations. In various construction projects, reinforced concrete is a commonly utilised material due to its high strength and durability. Reinforcement installations frequently employ steel rebars to provide structural stability in concrete formations. To ensure structural integrity, steel rebars must be securely tied at intersections, thereby reinforcing the overall structure. Traditional methods for tying rebars are generally manual, involving workers using hand tools to twist wire ties around rebar intersections. Such manual methods, while effective to some extent, are generally labour-intensive and time-consuming. Furthermore, manual tying techniques are subject to inconsistencies, which can compromise the uniformity of reinforcement ties and, consequently, the overall strength of reinforced structures.
Various automated systems have been developed to improve rebar tying processes. One known system incorporates an automated hand tool for twisting wire around rebar intersections, operated by an electric motor to perform the twisting action. Said system provides greater consistency than manual tying, as the motorised mechanism is controlled by a pre-set torque, ensuring uniform twist pressure across multiple rebar intersections. However, such a system frequently requires manual handling, limiting its effectiveness in large-scale applications. Furthermore, repeated manual handling of such automated tools can lead to worker fatigue, thereby reducing efficiency in high-volume construction projects. Said system also presents challenges with wire feeding mechanisms, leading to interruptions during tying operations, which results in increased project timelines and labour costs.
An alternative automated rebar tying system is operated by a robotic arm for entirely automated tying operations. Such a system positions the rebar at intersections and employs a rotating mechanism to twist wire around said intersections, offering full automation and high uniformity. Said system typically integrates a control system to adjust wire feed rates and tension, further enhancing the consistency of reinforcement ties. Despite such advantages, said system requires a complex setup process, and the associated costs of robotic equipment, control systems, and regular maintenance are substantial. Such complexities render said system less feasible for projects requiring frequent adjustments to rebar positions or orientations, particularly in non-standard construction projects where spatial constraints pose additional challenges. Moreover, robotic arms and control systems are highly sensitive to environmental factors, such as dust and vibration, which can affect operational accuracy and durability. Consequently, such a system lacks versatility for widespread application across diverse construction environments.
Furthermore, another system utilises pneumatic actuators to provide tension in wire during the rebar tying process. Said system uses compressed air to actuate wire-dispensing spools and provides tension adjustments through pneumatic control. Such an approach is primarily adopted to eliminate the dependency on electric motors, thereby offering certain advantages in energy-constrained environments. Nevertheless, pneumatic systems are associated with several limitations, including the requirement for a reliable air compressor, which introduces additional equipment costs and maintenance requirements. Moreover, pneumatic systems often experience fluctuations in air pressure, which can compromise the uniformity of reinforcement ties, leading to inconsistencies in structural stability. Additionally, pneumatic-based rebar tying systems are typically sensitive to temperature variations, which can further impact the performance and reliability of said systems.
Several other automated systems utilise wire tensioning mechanisms to achieve uniformity in rebar ties. Such systems employ mechanical springs, hydraulic cylinders, or servo motors to adjust wire tension, thereby enabling greater consistency in the tying process. However, said tensioning mechanisms are associated with limitations, including mechanical wear and calibration requirements, which necessitate frequent maintenance. Further, hydraulic and servo motor-based systems often involve intricate designs that increase the complexity of the equipment, resulting in elevated costs and reduced feasibility for small and medium-scale construction projects. In addition, environmental factors, such as dust and moisture, impact the reliability of hydraulic and servo motor-based systems, requiring additional protective measures.
In light of the above discussion, there exists an urgent need for solutions that overcome the problems associated with conventional systems and techniques for rebar tying in reinforcement installations.

As used herein, the term "automated rebar tying apparatus" refers to a device for reinforcement installation that enables automated wire tying around intersecting rebars to strengthen concrete structures. Such an apparatus is utilised in various construction applications where secure and uniform rebar ties are essential for structural integrity. The automated rebar tying apparatus generally includes multiple components that work in coordination to perform the tying process without requiring extensive manual intervention. The apparatus may be used in a range of environments, including high-rise construction, bridge building, and other large-scale infrastructure projects where reinforcement is applied through intersecting steel bars or rebars. Additionally, the automated rebar tying apparatus may include features enabling operational efficiency in various worksite conditions and with different rebar diameters or placements, thus providing a robust reinforcement installation in diverse construction applications. Said apparatus, therefore, is effective for providing reinforced structures with reliable and consistent wire ties to meet structural demands across multiple rebar intersections.
As used herein, the term "dual-arm assembly" refers to two parallel arms positioned on opposite sides of a rebar intersection for reinforcement installation. Each arm in the dual-arm assembly aligns opposite the other in a synchronised arrangement to facilitate wire tying at the rebar intersection. The dual-arm assembly is positioned to maintain stable alignment around the rebar intersection, enabling the precise placement of wire ties across various rebar configurations. Additionally, the dual-arm assembly may vary in size and positioning to adapt to different rebar intersection dimensions, thus providing versatility in reinforcement installations. Each arm typically includes associated mechanisms for extending wire to perform uniform tying, working in coordination with other components to enhance reinforcement quality. The dual-arm assembly provides a balanced and stable structure for the wire dispensing operation, contributing to uniform rebar ties across the rebar intersection, thereby assisting in reinforcement installation.
As used herein, the term "wire dispensing spool" refers to a rotatable component that dispenses wire for tying purposes at a rebar intersection in a reinforcement installation process. Each wire dispensing spool is mounted on the arms of the dual-arm assembly, facilitating the synchronized release of wire around the rebar intersection. Such wire dispensing spools are operatively connected to tension regulators, which adjust the wire feed in coordination with spool rotation to ensure consistent tension during the tying process. The wire dispensing spool operates to maintain a steady supply of wire as required during the tying process, providing precise wire placement around each rebar intersection. The wire dispensing spool is adaptable for use with different wire diameters, making it suitable for various reinforcement requirements. Additionally, said spool may include a structure that allows for easy replacement or reloading of wire, further improving efficiency in reinforcement installation applications.
As used herein, the term "tension regulator" refers to a device that controls the tension of the wire being dispensed by the wire dispensing spool during a rebar tying process in reinforcement installation. Each tension regulator is aligned with the corresponding wire dispensing spool to provide consistent control over the wire feed, thereby enabling uniform tension across the rebar intersection. Such a tension regulator adjusts the wire release speed in coordination with spool synchronization, ensuring that the wire does not become loose or overly taut while forming a tie around the rebar. The tension regulator is generally adjustable, allowing for modifications in wire tension to accommodate different rebar sizes and configurations. Additionally, the tension regulator can incorporate feedback mechanisms to monitor wire feed during the tying process, thus maintaining optimal wire tension in various reinforcement installation conditions. Said tension regulator, through its precise adjustment capability, aids in securing consistent reinforcement ties across multiple intersections.
As used herein, the term "central twist mechanism" refers to a component positioned between the dual-arm assembly that coordinates the twisting of the dispensed wire at the rebar intersection in a reinforcement installation process. The central twist mechanism engages both wire dispensing spools to twist the wire uniformly around intersecting rebars, ensuring secure and balanced reinforcement ties. Such a twist mechanism is centrally positioned to facilitate equal engagement with the dual-arm assembly, enabling synchronized operation during the twisting process. The central twist mechanism may include rotational elements that work in tandem with the arms, providing precise control over the twisting action at each rebar intersection. Said twist mechanism is generally adaptable to various tie formations, allowing for adjustments based on the reinforcement requirements at each installation site. The central twist mechanism enables efficient twisting of wire across multiple rebar intersections, contributing to the uniformity and stability of reinforcement installations.
FIG. 1 illustrates an automated rebar tying apparatus (100) for reinforcement installation, in accordance with the embodiments of the present disclosure. In an embodiment, an automated rebar tying apparatus 100 includes a dual-arm assembly 102 positioned on opposite sides of a rebar intersection. The dual-arm assembly 102 comprises two arms 102 arranged in opposing alignment around the rebar intersection, facilitating optimal alignment for uniform reinforcement. Each arm 102 includes a wire dispensing spool 104 extending along the length of the arm 102 in a synchronized relationship with the opposite arm 102. The positioning of the dual-arm assembly 102 on either side of the rebar intersection provides a balanced approach to the tying process, allowing for equal engagement of the wire from each spool 104 to be fed around the rebar intersection simultaneously. The synchronized relation between each arm 102 allows both wire dispensing spools 104 to work in concert, coordinating the release of wire, and aligning with other mechanisms of the apparatus 100 to achieve a cohesive wire tie. Each arm 102 may be configured to support variations in rebar diameters and intersections through the synchronized movement of the dual-arm assembly 102, allowing the apparatus 100 to adapt to different reinforcement conditions in various construction applications. The dual-arm assembly 102 can be adapted to operate in different orientations as well, facilitating reinforcement installation from multiple angles. Additionally, the dual-arm assembly 102 is structured to accommodate operational forces exerted during the tying process, maintaining stability throughout repeated operation cycles.
In an embodiment, each wire dispensing spool 104 is operatively associated with a tension regulator 106 to regulate the release and feed of wire during the tying process. Each tension regulator 106 is aligned with the corresponding wire dispensing spool 104 to control the synchronization of wire feed, ensuring uniformity at the rebar intersection. The tension regulator 106 adjusts the release tension of the wire based on real-time requirements, reducing the risk of wire breakage or inconsistencies in the tie around the rebar. The tension regulator 106 is generally positioned adjacent to the wire dispensing spool 104, facilitating direct regulation of the wire feed and maintaining constant alignment with the spool 104. In various embodiments, each tension regulator 106 is adaptable to accommodate different wire types and diameters, enabling versatility in reinforcement applications. The alignment between each tension regulator 106 and the corresponding spool 104 contributes to a consistent and balanced feed rate, ensuring each wire tie forms with consistent pressure. The tension regulator 106 may also incorporate feedback mechanisms to continuously adjust wire feed according to the requirements of the rebar diameter and configuration, maintaining steady tension throughout the process. The integration of tension regulators 106 with the wire dispensing spools 104 provides an efficient means of managing wire feed, enhancing the accuracy and reliability of each tie formed at the rebar intersection.
In an embodiment, the automated rebar tying apparatus 100 includes a central twist mechanism 108 positioned between the dual-arm assembly 102 to facilitate the twisting of wire at the rebar intersection. The central twist mechanism 108 is located centrally between the two arms 102 and aligned with the wire dispensing spools 104 to provide coordinated engagement with both spools 104. The twist mechanism 108 operates in synchronization with the dual-arm assembly 102, twisting the wire as it feeds from each spool 104, forming a secure tie around the rebar intersection. The positioning of the central twist mechanism 108 allows equal engagement with each arm 102 and wire dispensing spool 104, contributing to uniform and simultaneous wire twisting around the rebar intersection. The twist mechanism 108 may include rotational elements aligned with each spool 104, ensuring consistent application of twisting force and maintaining uniformity in the tie. Additionally, the twist mechanism 108 can be adapted to accommodate different tie formations and wire diameters, allowing the apparatus 100 to adapt to a variety of reinforcement conditions and configurations. The placement of the central twist mechanism 108 also minimizes the likelihood of entanglements, facilitating smoother wire feed from each spool 104. The central twist mechanism 108 enables a balanced application of twisting action, maintaining consistency and stability throughout the tying process. The central position of the twist mechanism 108 within the apparatus 100 further supports the alignment and coordination of all elements involved in the tying process, enabling efficient and reliable reinforcement installation across multiple rebar intersections.
In an embodiment, each arm 102 of the automated rebar tying apparatus 100 includes a positioning sensor that aligns precisely with the wire dispensing spool 104. Said positioning sensor is integrated with each arm 102 to detect and maintain the correct alignment of both arms 102 relative to the rebar intersection during the wire tying process. Such alignment, verified by the sensor, enables consistent positioning of each arm 102, thereby promoting accurate wire placement across every tie formed around the rebar intersection. The sensor actively monitors the spatial relationship between the arm 102 and the intersection, transmitting feedback to ensure that each arm 102 remains in correct alignment. By detecting slight misalignments or positional shifts, the sensor adjusts the orientation of each arm 102, thus compensating for any variances caused by operational conditions or irregularities in the rebar structure. The positioning sensor is capable of adapting to different rebar intersections and configurations, enabling its use in varied reinforcement applications. In certain applications, the positioning sensor may include a laser or optical sensor that determines arm orientation and adjusts in real-time to ensure consistent wire placement throughout the operation. The continuous monitoring capability of the positioning sensor facilitates a controlled, precise placement of wire at the intersection, thereby improving the uniformity and reliability of each reinforcement tie.
In an embodiment, each wire dispensing spool 104 in the automated rebar tying apparatus 100 is positioned in a rotational relationship with the tension regulator 106, allowing the spool 104 to adjust its feed rate based on real-time feedback. Said rotational positioning enables each spool 104 to release wire in response to variable tension levels managed by the tension regulator 106, thus ensuring balanced tension throughout the tying process. The rotational relationship allows each spool 104 to modify its output rate as necessary, reducing instances of excessive or inadequate wire release and minimizing wire slippage. The tension regulator 106 interacts with each spool 104 by actively adjusting the release speed according to the rebar's structural requirements, adapting as necessary for optimal wire placement. Each spool 104 rotates independently, thereby aligning with changes in tension imposed by the tension regulator 106, which continually monitors and adjusts based on feedback from operational sensors. Such rotational adjustment is particularly beneficial for applications requiring frequent or rapid tension shifts due to rebar irregularities or spatial constraints. Furthermore, the rotational design of the spool 104 minimizes wear on the wire during feeding and allows for adjustments based on spool size and wire material, ensuring compatibility with different wire types. This configuration supports continuous and consistent wire feeding, adapting to varied reinforcement specifications and requirements.
In an embodiment, each arm 102 of the automated rebar tying apparatus 100 is pivotally aligned with the central twist mechanism 108, enabling synchronized movement of the wire dispensing spools 104 in response to the rotational action of the twist mechanism 108. Said pivotal alignment facilitates coordinated movement between each arm 102 and the central twist mechanism 108, which operates to twist the dispensed wire around the rebar intersection. By positioning each arm 102 pivotally relative to the twist mechanism 108, the apparatus 100 maintains a stable, synchronized movement of both spools 104, thus contributing to consistent wire placement. The pivotal alignment allows each arm 102 to follow the rotation of the twist mechanism 108 precisely, ensuring that both spools 104 operate in unison while feeding and twisting wire. Each arm 102 pivots in response to the rotational force generated by the central twist mechanism 108, creating a smooth, uninterrupted motion that reduces strain on the wire and minimizes irregularities in wire twists. Such pivotal alignment further adapts to rebar configurations of varying diameters, facilitating the formation of ties at intersections where adjustments in arm positioning may be necessary. In additional embodiments, each arm 102 may include an adjustable pivot point, allowing the angle and range of motion to be modified based on the rebar size and alignment. The alignment between the arms 102 and the twist mechanism 108 enables reliable wire twisting across multiple intersections.
In an embodiment, each tension regulator 106 of the automated rebar tying apparatus 100 is positioned in adjustable coupling with the dual-arm assembly 102, allowing the regulator 106 to modify wire tension proportionally across both spools 104. Such adjustable coupling enables the tension regulator 106 to balance the wire tension as required for uniform tightening around the rebar intersection. Each regulator 106 interacts with the dual-arm assembly 102, distributing the tension proportionally to ensure that wire feed from each spool 104 is consistent and balanced. The adjustable coupling provides a means for each regulator 106 to dynamically alter wire tension according to the operational requirements of the rebar intersection. By adjusting the tension proportionally across both arms 102, the tension regulator 106 prevents excessive force on any single spool 104, thus avoiding wire breakage or slippage. Each regulator 106 can modify tension based on feedback from sensors monitoring the alignment and positioning of the arms 102, further enhancing the consistency of wire placement. Said coupling may also incorporate mechanisms that facilitate adjustments based on changes in rebar size or configuration, enabling the regulator 106 to adapt to different reinforcement requirements. Such adjustable coupling is adaptable to various reinforcement applications, providing a controlled and consistent tension across multiple rebar intersections.
In an embodiment, the twist mechanism 108 in the automated rebar tying apparatus 100 includes a guide element positioned in parallel alignment with the tension regulators 106. Said guide element operates to direct the wire during the twisting process, maintaining uniform tie formation around each rebar intersection. The guide element aligns with the twist mechanism 108 to channel the wire as it is dispensed from each spool 104, thereby preventing the wire from deviating or becoming entangled. By directing the wire in a controlled path during twisting, the guide element contributes to the structural integrity of the reinforcement tie. Such parallel alignment of the guide element with the tension regulators 106 enhances the coordination between wire feed and tension control, allowing each wire to be consistently directed toward the rebar intersection. The guide element may also include adjustable positioning features, allowing alignment modifications to accommodate different rebar diameters or configurations. In various embodiments, the guide element incorporates a smooth, friction-resistant surface that reduces wear on the wire as it passes through the twist mechanism 108. This configuration supports consistent wire placement and minimizes irregularities in the tie formation.
In an embodiment, each wire dispensing spool 104 in the automated rebar tying apparatus 100 maintains a lateral relationship with the twist mechanism 108, enabling each spool 104 to rotate independently in response to tension adjustments made by the regulators 106. Said lateral positioning of each spool 104 allows for individual rotational adjustments that synchronize with the requirements of the rebar intersection, thus ensuring smooth wire feed during tying. The lateral alignment facilitates independent rotation, minimizing wire entanglement or overlap between spools 104 as the wire is dispensed. Such lateral positioning of each spool 104 relative to the twist mechanism 108 allows each spool to align its output according to the feedback from the tension regulators 106, providing a steady and controlled release of wire at the rebar intersection. The lateral alignment may also allow each spool 104 to maintain tension variations without affecting the other spool 104, enabling balanced wire placement on both sides of the rebar intersection. Additionally, the independent rotation of each spool 104 allows adjustments based on wire type and diameter, enhancing versatility across different reinforcement applications.
In an embodiment, each arm 102 of the automated rebar tying apparatus 100 includes a locking feature that engages with each spool 104, holding each spool 104 in place during the tie formation around the rebar intersection. Said locking feature provides temporary stabilization of each spool 104, ensuring that the spool 104 remains stationary as the wire forms a tie around the rebar intersection. By holding each spool 104 in place during the tying process, the locking feature prevents displacement or shifting that could compromise the accuracy of the wire wrap. The locking feature aligns with the spool 104 during the initial wire placement and engages to secure the spool 104 as the wire is twisted. Such alignment is designed to maintain control over the spool 104 during tie formation, preventing unintentional movement or misalignment. The locking feature may include mechanisms to release each spool 104 after each tie is completed, facilitating repeated tying operations at various intersections. Additionally, the locking feature allows for rapid adjustment to accommodate different rebar configurations, making it suitable for varied reinforcement installations.
In an embodiment, the twist mechanism 108 of the automated rebar tying apparatus 100 includes a torque limiter connected to the dual-arm assembly 102 to control the applied twisting force during the wire tying process. Said torque limiter restricts excessive force exerted by the twist mechanism 108, thereby protecting the wire from breakage and preventing over-tightening of each tie around the rebar intersection. The torque limiter interacts with the twist mechanism 108 to maintain a steady application of force, adjusting as necessary to meet the structural requirements of the rebar. Positioned within the twist mechanism 108, the torque limiter allows the apparatus 100 to maintain uniform tie formation without damaging the wire, even under variable tension. The torque limiter is adjustable, allowing the twist force to be modified according to the rebar size and tie specifications. Such an arrangement minimizes the likelihood of wire deformation and enhances the reliability of each reinforcement tie.
In an embodiment, each tension regulator 106 of the automated rebar tying apparatus 100 is coupled with a feedback loop sensor that monitors wire tension at each spool 104 and adjusts said regulator 106 accordingly. The feedback loop sensor detects real-time tension levels at each spool 104, transmitting feedback to the tension regulator 106, which then modifies tension as necessary to maintain consistency. Such coupling of the feedback loop sensor with the tension regulator 106 enables the apparatus 100 to monitor and adapt to changes in wire tension throughout the tying process. The sensor is capable of detecting variations in tension that arise from differences in rebar diameter or positioning, allowing the regulator 106 to compensate and maintain uniform wire placement. The feedback loop sensor operates continuously, providing real-time adjustment capabilities that ensure stable wire tension across varied reinforcement applications.
FIG. 2 illustrates a class diagram of the automated rebar tying apparatus 100 for reinforcement installation, in accordance with the embodiments of the present disclosure. The automated rebar tying apparatus 100 for reinforcement installation features a dual-arm assembly 102 positioned on opposing sides of a rebar intersection. Each arm in assembly 102 includes a wire dispensing spool 104, extending along each arm in synchronized relation to enable balanced wire feeding around the rebar intersection. Each spool 104 is connected to a tension regulator 106, allowing precise adjustment of wire feed, securing uniform ties across intersections. A central twist mechanism 108 is located between the dual-arm assembly 102, coordinating the engagement of both spools 104. This central twist mechanism 108 incorporates a guide element, aligning in parallel with tension regulators to direct the wire smoothly during twisting. Additionally, a torque limiter within the twist mechanism 108 limits excessive force during wire twisting, ensuring consistent and secure reinforcement. The apparatus's components work in coordination to provide stable and accelerated reinforcement installation, accommodating various rebar sizes and layouts.
In an embodiment, dual-arm assembly 102 is positioned on opposite sides of a rebar intersection, with each arm 102 opposing the other, providing balanced alignment for wire tying. Each arm 102 includes a wire dispensing spool 104 extending along its length in synchronized relation to the other arm 102. This opposing alignment minimizes lateral movement, creating stable, consistent alignment for each wire tie. The synchronized relation of spools 104 on each arm 102 allows simultaneous wire feed, reducing uneven tension and promoting uniformity across each tie. The dual-arm assembly 102 further stabilizes the tying process by securing the rebar in place between the arms, thus maintaining a steady hold that reduces repositioning delays. The overall configuration supports consistent, uniform rebar tying across varying intersection angles and structures, reducing the likelihood of shifting or misalignment.
In an embodiment, each wire dispensing spool 104 is operatively associated with tension regulators 106, with each tension regulator 106 aligned to adjust the wire feed based on spool synchronization, securing a uniform tie at the rebar intersection. The alignment between each spool 104 and regulator 106 supports real-time wire adjustment, allowing each spool to maintain consistent tension at the intersection. This regulated adjustment helps prevent over-tightening or slack, which could otherwise impact structural integrity. Tension regulators 106 contribute to uniformity in wire ties by balancing spool feed rates according to the specific requirements of each intersection. This minimizes variations in tension across the apparatus and prevents potential wire slippage, further supporting consistent reinforcement installation.
In an embodiment, central twist mechanism 108 is positioned between dual-arm assembly 102 to engage both spools 104 in a coordinated twisting motion. This centralized placement of twist mechanism 108 enables balanced engagement with each arm 102, facilitating synchronized twisting of wire at the rebar intersection. The twist mechanism 108 provides a balanced application of rotational force, promoting even twists in the wire, which enhances overall stability of each tie. Positioned centrally, twist mechanism 108 supports continuous wire twisting without causing unbalanced tension, thus supporting smooth, uninterrupted operation. Twist mechanism 108 is adaptable to various wire gauges, enabling seamless adjustments for different rebar configurations.
In an embodiment, each arm 102 includes a positioning sensor aligned with wire dispensing spool 104 to detect precise alignment of the arms relative to the rebar intersection. The positioning sensor continuously monitors the position of each arm 102 in real-time, allowing any necessary adjustments to maintain accuracy across each tie. Said sensor allows each arm 102 to remain precisely aligned with the intersection, improving the consistency of wire placement while reducing the risk of misalignment. The sensor's real-time feedback assists in detecting minor shifts that may occur due to external factors, enabling adjustments that prevent inconsistencies in reinforcement ties. This precise alignment feature is highly adaptable to different rebar orientations and is particularly beneficial in large-scale or complex rebar layouts, where accuracy is essential for structural reinforcement.
In an embodiment, each wire dispensing spool 104 is positioned in rotational relation with tension regulators 106, enabling real-time adjustment of feed rate based on tension feedback. The rotational positioning of spool 104 allows controlled wire release by synchronizing with the tension regulator 106, maintaining balanced wire tension throughout the tying process. This dynamic adjustment in real-time provides the flexibility required to manage fluctuating tension demands during operation, minimizing slippage while promoting a stable wire feed rate. The rotational relationship further supports various wire diameters and materials, enhancing versatility in different reinforcement scenarios. Independent rotation of each spool 104 allows the apparatus 100 to adapt to various rebar configurations without requiring manual tension adjustments.
In an embodiment, each arm 102 is pivotally aligned with central twist mechanism 108, allowing synchronized movement of spools 104 in response to twist mechanism rotation. The pivotal alignment enhances consistency of the wire twisting process by enabling each arm 102 to maintain uniform movement around the intersection, preventing tension imbalances that could compromise wire integrity. By following the motion of twist mechanism 108, each arm 102 maintains a coordinated movement that reduces potential stress on the wire. This alignment allows the apparatus 100 to operate efficiently in varied rebar configurations, maintaining consistent tie formation without manual adjustments. The pivotally aligned structure supports flexible positioning around complex intersections, improving reinforcement stability across different rebar angles.
In an embodiment, each tension regulator 106 is positioned in adjustable coupling with dual-arm assembly 102, allowing proportional modification of wire tension across both spools 104. This coupling helps each regulator 106 balance tension according to the real-time requirements of both spools, ensuring even tightening around the rebar intersection. Adjustable coupling allows each regulator 106 to adapt tension based on variations in wire feed requirements, which prevents undue strain on any single spool 104. The proportional adjustment capability of each regulator 106 minimizes inconsistencies in wire tension across spools, supporting uniform reinforcement. The configuration reduces the risk of over-tightening, which can otherwise weaken wire integrity, while facilitating efficient installation of rebar ties across multiple intersections.
In an embodiment, twist mechanism 108 includes a guide element positioned in parallel alignment with tension regulators 106 to direct wire consi
