Description

Technical Field

[0001] This utility model relates to the field of steel bar processing technology, specifically to a steel bar ring auxiliary gathering structure. Background Technology

[0002] In the field of steel bar processing, bending steel bars into ring structures (i.e., steel bar rings) using specific methods is one of the more common processing steps. Typically, after the steel bar rings are formed, they need to undergo a cooling process. Once the cooling process is complete, i.e., after the previous station's steel bar ring gathering is finished, the transfer port of the previous station will discharge the cooled steel bar ring and send it into the gathering and stacking structure. After being gathered in the gathering and stacking structure, it can be rotated and transferred to the next station for subsequent binding and other operations. Only then can it meet the conditions for leaving the factory and enter the next stage of application.

[0003] During the rebar coil tightening process, to provide a certain level of protection for the rebar coils and minimize the possibility of overlapping between them, protective frames are often installed on the outside of the through-tube rod used to assist in tightening, such as... Figure 4 At point A. The protective frame can provide a certain degree of protection and also has a certain inhibitory effect on the overlapping and entanglement of the reinforcing steel rings.

[0004] However, the protective frames currently used in rebar ring processing often fail to provide convenient passage for multiple rebar rings to pass smoothly through the threaded rod during actual use. In the processing flow, it is usually necessary to deploy two protective frames using specialized equipment to create space for the rebar rings to pass through and enter subsequent processing steps. This method, to some extent, impacts the overall efficiency of the rebar ring gathering process, potentially hindering processing progress and failing to fully meet the efficiency requirements in certain scenarios. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the existing rebar gathering ring cannot efficiently supply the rebar ring for subsequent processing, and to provide a rebar ring auxiliary gathering structure.

[0006] To address the shortcomings of the aforementioned technical problems, the present invention adopts the following technical solution: a rebar ring auxiliary gathering structure, which has a base and two through-columns located at the center of the base. The two through-columns are arranged in an L-shape and can pass through multiple rebar rings discharged from the transmission port of the previous work station. After being driven to rotate, the through-columns are transferred to the next work station. The base is provided with two protective frames spaced apart, and the two protective frames are distributed in a ring around the transmission port of the previous work station to restrict and guide multiple rebar rings to pass through the through-columns. The gap between the two protective frames forms a first channel for the through-sleeve column to pass through, and the protective frame is composed of a plurality of vertical rods fixed on the base; The lower ends of the two vertical bars near the next work station are each composed of rotatable plumb bars, and when the plumb bars are rotated and tilted toward the next work station, the corresponding vertical bars can form a second channel for the steel bar ring to pass through.

[0007] As a further optimization of the steel bar ring auxiliary gathering structure of this utility model: the protective frame is provided with a limiting block, which is set on the side of the vertical rod facing the upper station transmission port to prevent the vertical rod from rotating towards the upper station transmission port.

[0008] As a further optimization of the steel bar ring auxiliary binding structure of this utility model: an elastic rubber layer is fixedly provided on the side of the limiting block facing the vertical rod.

[0009] As a further optimization of the steel bar ring auxiliary binding structure of this utility model: multiple reinforcing rings are provided on the multiple vertical rods and are arranged perpendicularly to the vertical rods.

[0010] As a further optimization of the steel bar ring auxiliary converging structure of this utility model: the spacing of the vertical rods at the edge of the first channel is 1.1 to 1.3 times the diameter of the cross-section of the sleeve column, and the spacing between the two vertical rods forming the second channel is 1.1 to 1.3 times the diameter of the cross-section of the steel bar ring.

[0011] As a further optimization of the steel bar ring auxiliary binding structure of this utility model: a reinforcing bar is provided between the vertical rod and the base to connect the two, and the reinforcing bar is a triangular plate.

[0012] As a further optimization of the steel bar ring auxiliary gathering structure of this utility model: the top of the multiple vertical rods is provided with a guide part, the guide part is set in a funnel shape, and the flared end of the guide part faces the transmission port of the previous station.

[0013] As a further optimization of the steel bar ring auxiliary binding structure of this utility model: the vertical rod and the vertical rod are both made of hollow metal tubes.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This invention uses two spaced-apart, ring-shaped protective frames to restrict the reinforcing bar rings located on the through-column at the center of the ring. This reduces the likelihood of the reinforcing bar rings overlapping and scattering, and lowers the risk of injury to workers from flying reinforcing bar rings. Furthermore, the gap between the two protective frames forms a first channel through which the through-column can pass back and forth. Simultaneously, a rotatable plumb line is installed in a second channel connected to the first channel. This plumb line works in conjunction with the protective frames to restrict and block the reinforcing bar rings. When the through-column carries the reinforcing bar ring through, the plumb line can be directly compressed and deformed, facilitating the smooth passage of the reinforcing bar ring through the second channel. This effectively restricts and guides the reinforcing bar rings while maintaining efficient transmission.

[0015] This invention uses a plumb line to move multiple steel rings downwards to the next work position as the sleeve column moves them. This helps to disperse the steel rings to some extent, further reducing the probability of overlapping steel rings affecting subsequent binding. Attached Figure Description

[0017] To better understand this utility model, the following embodiments further illustrate the content of this utility model, but the content of this utility model is not limited to the following embodiments.

[0018] like Figure 1 As shown, a steel bar ring-assisted convergence structure has a base 1, within which a power-driven transmission shaft is installed. Two L-shaped through-sleeve columns 2 are mounted on the transmission shaft. (See diagram). Figure 2 As shown, when any of the sleeve columns 2 rotates to a vertical position, it receives the steel bar rings 8 conveyed from the previous station via a conveyor belt and discharged from the corresponding transmission port. The steel bar rings 8 naturally settle onto the sleeve column 2 under their own weight. Multiple steel bar rings 8 can be settled at a time to form a group. After the steel bar rings 8 are fully settled, a proximity switch sends a signal to the control system, driving the sleeve column 2 to rotate around the drive shaft. Figure 3As shown, after the flipping action is completed, the sleeve column 2 with the steel bar ring 8 is horizontally distributed, and its axis is coaxial with the conveying track of the next station. At the same time, another sleeve column 2 rotates to a vertical position, with its top end corresponding to the discharge port of the previous station, ready to receive the next set of steel bar rings 8. The horizontally distributed steel bar rings 8 are then clamped and pulled out from the sleeve column 2 by the pneumatic gripper device, and finally the steel bar rings 8 are smoothly conveyed to the next station for subsequent processing.

[0019] Two protective frames 3 are fixedly installed on the top of the base 1 by welding. The two protective frames 3 are symmetrically distributed, forming an annular protective space with a through gap. This gap constitutes the first channel 5, the width of which matches the diameter of the through-sleeve column 2, ensuring that the through-sleeve column 2 can be smoothly rotated within it. A notch is opened on the side of the protective frame 3 facing the next work station. This notch, together with the gap between the two protective frames 3, forms the second channel 4. The height of the channel is greater than the diameter of the reinforcing ring 8, ensuring that the through-sleeve column 2 and the reinforcing ring 8 can pass through smoothly. In terms of specific dimensions, the distance between the edges of the two protective frames 3 forming the first channel 5 is set to an appropriate multiple of the cross-sectional diameter of the through-sleeve column 2, specifically 1.1 times, thus providing the necessary space for the rotation of the through-sleeve column 2. The distance between the edges of the two protective frames 3 forming the second channel 4 is set to an appropriate multiple of the distance between the cross-sections of the required constricted reinforcing ring 8, specifically 1.1 times, ensuring that the reinforcing ring 8 does not rub or collide with the protective frames 3 when passing through. Two symmetrical vertical rods 7 are arranged inside the second channel 4. The vertical rods 7 are made of hollow steel pipes, and their length is adapted to the height of the protective frame 3. They can naturally fill the gap formed by the second channel 4, thus forming the complete structure of the first channel 5. The first end of the vertical rod 7 is rotatably mounted on the inner wall of the protective frame 3 via a hinge structure. The hinge is made of stainless steel and chrome-plated to improve wear resistance. The second end of the vertical rod 7 hangs naturally above the base 1, at an appropriate height from the surface of the base 1. Before the reinforcing bar ring 8 falls from the previous station into the through-column 2, the two vertical rods 7 remain vertical under gravity, forming a closed annular space with the protective frame 3. This helps to tighten the reinforcing bar ring 8, restricting its lateral displacement during the installation process, ensuring that the reinforcing bar ring 8 can be stably installed onto the through-column 2, and reducing the probability of overlap between the reinforcing bar rings 8 to a certain extent. Figure 2As shown, when the through-sleeve column 2 drives the rebar ring 8 to the next station, the through-sleeve column 2 will drive the rebar ring 8 to perform a circular motion. At this time, the entire through-sleeve column 2 will pass through the first channel 5 and the closed channel formed by the second channel 4 covered by the plumb rod 7 in sequence, thus ensuring that the through-sleeve column 2 will not be obstructed in its movement path. During the follow-up displacement of the rebar ring 8 with the through-sleeve column 2, its outer periphery will press against the first channel 5 formed by the plumb rod 7. Since the plumb rod 7 can only rotate outward, under the pressure of the rebar ring 8, the plumb rod 7 will rotate outward around the hinge axis, thus forming the second channel 4 for the rebar ring 8 to pass through. During the process of the rebar ring 8 pressing against the plumb rod 7 to form the second channel 4 and passing through, the free end of the plumb rod 7 will contact the surface of the rebar ring 8. Under the action of friction, the rebar ring 8 will be moved, causing the rebar ring 8 that may overlap to rotate relative to each other, further avoiding the situation of the rebar ring 8 being stacked, thus ensuring that the subsequent processes can proceed smoothly. Once the steel ring 8 has been completely transferred to the next work station and the two through-columns 2 have completed their reset rotation, the plumb rod 7 will rotate downwards synchronously under its own gravity to reset to its initial vertical state, thus preparing for the next steel ring 8 coiling protection and transfer operation.

[0020] A limiting block 6 is fixedly installed at the rotational connection between the plumb rod 7 and the protective frame 3. The limiting block 6 is fixed to the inner wall of the protective frame 3 by welding. Its position interferes with the rotation trajectory of the plumb rod 7, effectively limiting the displacement of the plumb rod 7 towards the inner direction of the two protective frames 3. The setting of the limiting block 6 can prevent the plumb rod 7 from hitting the steel ring already fitted on the through column 2 due to excessive rotation angle during the reset process. At the same time, it can also prevent the plumb rod 7 from directly colliding with the through column 2, thereby avoiding the scattering of the steel ring and damage to the surface of the through column 2. A layer of elastic rubber is glued to the side of the limiting block 6 facing the plumb rod 7 with strong adhesive. This rubber layer is made of nitrile rubber with good elasticity and wear resistance. When the plumb rod 7 resets and contacts the limiting block 6, the elastic rubber layer can absorb the impact force generated by the collision, reduce the rebound vibration of the plumb rod 7, and thus improve the speed at which the plumb rod 7 returns to a stable state during reset. This ensures that the plumb rod 7 can quickly form a complete ring protective structure with the protective frame 3, achieving an effective protection effect for the steel ring 8. In addition, the elastic rubber layer can reduce the number of impacts between the plumb rod 7 and the limiting block 6, thereby increasing the speed at which the plumb rod 7 resets and regains stability.

[0021] The protective frame 3 is composed of multiple vertical rods 302 fixedly connected by welding. These vertical rods 302 are evenly distributed on the top of any base 1, made of seamless steel pipe, and their length is determined according to the height of the reinforcing bar ring 8. The vertical rods 302 are vertically arranged, with their bottom ends connected to the base 1 by welding, and their top ends extending to near the top position of the through-column 2 when it is in a vertical state. The multiple vertical rods 302 are evenly distributed in a ring around the axis of the through-column 2 when it is in a vertical state. The spacing between adjacent vertical rods 302 is appropriate to form a protective frame, thereby enabling the protective frame 3 to effectively limit the reinforcing bar ring 8 from all directions. In the vertical direction of the vertical rods 302, a reinforcing ring 303 is set at appropriate intervals. The reinforcing ring 303 is also made of steel pipe and is fixedly connected to each vertical rod 302 by welding to form an integral frame structure, thereby improving the structural stability of the multiple vertical rods 302, preventing deformation during long-term use, and thus ensuring the protective and limiting effect on the reinforcing bar ring 8. Each of the vertical rods 302 has a guide section 304 at its top. The guide section 304 has a flared structure, with the flared end facing the direction of the upper station, and is funnel-shaped with an appropriate taper. The guide section 304 can effectively guide the steel ring 8 falling from the upper station. Even if there is a certain deviation in the falling position of the steel ring 8, it can be guided into the protective frame 3 by the inclined surface of the guide section 304, thereby improving the restrictive and guiding effect of the protective frame 3 on the steel ring 8. A triangular reinforcing rib 301 is also welded between each vertical rod 302 and the base 1. The reinforcing rib 301 is made of steel plate, with one end welded to the lower part of the vertical rod 302 and the other end welded to the upper surface of the base 1, forming a stable triangular support structure. This improves the stability of the connection between the vertical rod 302 and the base 1, while also enhancing the bending resistance of the vertical rod 302, maintaining the vertical stability of the vertical rod 302, and further improving the restrictive and guiding effect on the steel ring 8.

[0022] Specifically, at the edge of the protective frame 3 facing the next workstation, two adjacent vertical rods 302 are cut off at an appropriate height from the base 1, forming a gap for the steel reinforcement ring 8 to pass through. The first end of the plumb line 7 is hinged to the cut-off position of the vertical rod 302 at the edge via a hinge shaft structure, with the hinge shaft perpendicular to the axis of the vertical rod 302. Simultaneously, a protective block is welded at the cut-off point of the vertical rod 302. The protective block is made of rectangular steel plate, and its surface fits against the side of the plumb line 7. When the plumb line 7 is reset, the protective block can accurately position the plumb line 7, assisting in its rapid reset.

[0023] The vertical rods 302 of the protective frame 3 and the plumb rods 7 used to fill the gaps in the passage are both made of steel pipe. Steel pipe has good strength and toughness, meeting the structural strength requirements of the protective frame 3, and also has good weldability, facilitating processing and manufacturing. A hinge hole is provided at the center of the top of the plumb rod 7. The inner wall of the hinge hole is chamfered to reduce stress concentration. The hinge hole can be hinged to a groove located at the cut-off position of the vertical rod 302 at the edge. The width of the groove is slightly larger than the diameter of the plumb rod 7, ensuring that the plumb rod 7 can rotate flexibly. A limiting block 6 is welded to the side of the groove facing away from the next workstation. The limiting block 6 is a right-angled trapezoid, and its vertical surface contacts the side of the plumb rod 7 to limit the rotation angle of the plumb rod 7, ensuring that the plumb rod 7 can accurately return to its initial position after reset.

[0024] In this embodiment, the previous station is specifically the rebar ring 8 cooling conveyor station. This station mainly consists of a stainless steel conveyor belt, a cooling fan, and a temperature sensor. After the rebar ring 8 has undergone forming processing, it is conveyed to this station for cooling. The airflow of the cooling fan can be adjusted according to the temperature of the rebar ring 8. The temperature sensor monitors the surface temperature of the rebar ring 8 in real time. When the temperature drops below a set threshold, the rebar ring 8 is conveyed to this auxiliary gathering structure. The next station is the rebar ring 8 binding station, which is equipped with an automatic binding machine that can automatically bind the gathered rebar ring 8. The above two stations, as well as the power system and transmission structure that drive the two through-columns 2 to reciprocate, are all prior art well known to those skilled in the art. The power system uses a servo motor as the drive source and achieves precise control through a PLC control system. The transmission structure uses a combination of a gear reducer and a drive shaft to ensure smooth and reliable rotation of the through-columns 2. The specific structure and working principle of these prior art will not be described in detail here. Those skilled in the art can select and configure them according to actual needs.

[0025] The specific embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the substantive content of this utility model.
