Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of equipment for bundling cross-cut steel plate stacks, and in particular to an automatic bundling device for bundling cross-cut steel plate stacks and a working method. Background Art
[0002] Cross-cut steel plate stacks are stacks of neatly stacked steel plates after uncoiling, straightening, and cross-cutting. In order to prevent the stacks from falling apart during transportation, they must be bundled.
[0003] However, due to the wide variety of steel plate stack specifications, large variations in length, width, and height, and inconsistent bundling requirements, some steel plate stacks require one bundling pass, some require two, or even more, and the production process varies greatly. Therefore, manual bundling is currently the main method used. Manual bundling is prone to insufficient or excessive tension in the wound steel belt. Insufficient tension will cause the steel belt to loosen, while excessive tension may damage the edge of the steel plate. After bundling, the closed-loop steel belt will have four corners due to the right-angled edges on both sides of the steel plate, and the corners are almost right-angled, thereby increasing the risk of steel belt breakage. Summary of the Invention
[0004] The purpose of the present invention is to solve the problem that insufficient or excessive tension of the steel belt may occur during manual bundling, and insufficient tension may cause the steel belt to loosen, while excessive tension may damage the edge of the steel plate.

[0007] As a further description of the above technical solution: One end of the guide seat is semicircular, and the edges of the other lower connecting seat, the other upper connecting seat and the outer walls of the two guide seats are inclined.
[0008] As a further description of the above technical solution: Both sides of the outer wall of one of the lower connecting seats and one of the upper connecting seats are slidably connected with connecting rods through the second limiting sliding groove, and one end of the two connecting rods and the other two connecting rods are respectively connected to the other lower connecting seat and the other upper connecting seat.
[0009] As a further description of the above technical solution: A first spring is installed on the inner bottom wall of the first limiting slide groove, and the top of the first spring is connected to the bottom end of the upper connecting seat. A second spring is installed on the bottom of the outer wall of one of the lower connecting seats and the top of the outer wall of one of the upper connecting seats, and one end of the two groups of second springs are respectively connected to the other lower connecting seat and the other upper connecting seat.
[0010] As a further description of the above technical solution: The bonding mechanism also includes a bracket fixed to one side of the outer wall of the mounting frame, an electric push rod is fixed on the bracket, an opening adapted to the bonding piece is opened at one end of the mounting frame, a movable plate adapted to the opening is slidably connected to one side of the inner wall of the mounting frame, and one end of the electric push rod is connected to the movable plate.
[0011] As a further description of the above technical solution: The laminating mechanism also includes a horizontal plate fixed on the belt guide device, a U-shaped seat is fixed on the horizontal plate, a baffle is rotatably connected inside the U-shaped seat, and a torsion spring is commonly provided at both ends of the baffle and the U-shaped seat, so that the baffle can automatically reset to a vertical state after being driven by the laminating member to rotate forward, and a baffle bar for keeping the baffle in a vertical state is fixed on one side of the upper surface of the U-shaped seat, so that the baffle will not continue to rotate backward after being reset to the vertical state.
[0012] As a further description of the above technical solution: The other end of the mounting frame is equipped with a motor, the output end of the motor is spline-connected to one end of the threaded rod, the push plate is slidably connected to the middle of the mounting frame, and the size of the push plate is adapted to the inner cavity of the storage box.
[0013] As a further description of the above technical solution: One side of the steel strip unwinding mechanism is equipped with an upper winding cantilever crane, and both sides of the six-axis robot are installed with safety guardrails, and one side of the safety guardrails is equipped with a control cabinet with a touch screen, and the belt guide device is equipped with a photoelectric sensor and a precision encoder.
[0014] A method for operating an automatic bundling device for cross-cutting steel plate stacks comprises the following steps: S1. Before production, the baling passes and baling positions are set using a control system in a control cabinet with a touch screen. During production, the cross-cut steel sheet stacks are transported to the belt guide via a conveyor mechanism, triggering a photoelectric sensor. Simultaneously, a precision encoder detects the travel distance of the cross-cut steel sheet stacks. Once the stacks reach the set baling position, the conveyor mechanism stops. Next, the motor is started to drive the threaded rod to rotate, which in turn drives the push plate to push the fittings in the storage box toward the cross-cutting steel plate, so that the front-end fittings abut against the side of the cross-cutting steel plate. Then, after turning off the motor, the electric push rod is started to cause the moving plate to push the fittings forward until they abut against the baffle. At this time, the fittings remain in this state and do not move. S2, then control the baling head to feed the steel belt along the belt guide device to form a closed loop around the cross-section of the steel plate stack. At the same time, the position of the steel belt after the closed loop is adapted to the portion of the two fittings exposed outside the mounting frame. Then start the six-axis robot to carry the baling head downward and press it on the steel plate stack, triggering the limit switch on the baling head. At this time, the baling head retracts, tightens, locks, and cuts the belt, completing the baling action. In the process of winding the belt, the inner wall of the steel belt gradually abuts against the outer wall of the fitting, and the semicircular end of the guide seat drives the four corners of the tightened steel belt to turn into a semicircular shape; S3. After the bundling of this pass is completed, the six-axis robot carrying the bundling head automatically returns to the standby position, and then starts the conveying mechanism, cross-cutting the steel plate stack and continues to move to the next bundling position, repeating the above operation process to complete all bundling operations.
[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: The conveying mechanism, baling head and laminating mechanism are configured to achieve fully automatic baling of the cross-cut steel plate stacks conveyed on the conveying mechanism. At the same time, after the closed-loop steel belt is tightened, the corners are driven by the guide seat to form a semicircular shape, which greatly reduces stress concentration. This prevents the steel belt used for baling from breaking during the transportation of the bundled cross-cut steel plate stacks and avoids damage to the edges of the steel plate stacks. At the same time, after completing one bundling pass, the steel plate stack is kept in the middle position on the conveyor surface during its movement due to the action of the fittings fixed on both sides of the steel plate stack due to the tightening of the steel belt and the next fittings abutting against both sides of the steel plate stack, thereby avoiding deviation and ensuring the smooth progress of the bundling operation in the subsequent passes. Furthermore, the second springs between the two lower connecting seats and the two upper connecting seats can dynamically compensate for the tension of the steel belt to avoid being too loose or too tight. At the same time, the fittings can be recovered and recycled. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.
[0019] like Figure 1 - Figure 10 As shown, the present invention provides: An automatic bundling device for cross-cutting steel plate stacks includes a conveying mechanism 10 and a belt guide device 20 mounted on the conveying mechanism 10. A six-axis robot 30 is provided on one side of the belt guide device 20. A bundling head 40 is mounted on one end of the six-axis robot 30. A steel strip buffer mechanism 50 is installed on one side of the six-axis robot 30. A steel strip unwinding mechanism 60 is mounted on one side of the steel strip buffer mechanism 50. A top-rolling cantilever crane is mounted on one side of the steel strip unwinding mechanism 60. After the steel strip on the steel strip unwinding mechanism 60 is used, the empty strip roll on the steel strip unwinding mechanism 60 is first hoisted out by the top-rolling cantilever crane, and then a new steel strip is hoisted and placed in the steel strip unwinding mechanism 60 for replacement. Safety guardrails are installed on both sides of the six-axis robot 30, and a control cabinet with a touch screen is mounted on one side of one of the safety guardrails. A photoelectric sensor and a precision encoder are mounted in the belt guide device 20. In further detail, Figure 1 、 Figure 4 、 Figure 5 and Figure 7 As shown, a fitting mechanism 70 is mounted on the inner wall of the belt guide device 20. The fitting mechanism 70 includes a mounting frame 71 and a storage box 72 assembled in the mounting frame 71. A plurality of fitting members 73 are inserted into the storage box 72. A threaded rod 74 is rotatably connected to the mounting frame 71. A push plate 76 is connected to the threaded rod 74 via a threaded sleeve 75. The fitting members 73 are pushed by the push plate 76 to fit the side surface of the cross-cutting steel plate, thereby achieving the turning and guiding of the steel strap for bundling. The other end of the mounting frame 71 is equipped with a motor 711, the output end of the motor 711 is spline-connected to one end of the threaded rod 74, and a push plate 76 is slidably connected to the middle of the mounting frame 71, and the size of the push plate 76 is adapted to the inner cavity of the storage box 72; Specifically, the mounting frame 71 is fixed to the belt guide device 20 by bolts. At the same time, the storage box 72 is connected to the mounting frame 71 by plugging. A knob bolt is provided on the outer wall of the storage box 72. At the same time, a threaded hole adapted to the knob bolt is opened at a corresponding position of the mounting frame 71. After the storage box 72 is plugged in, the knob bolt is tightened to fix it, so that the storage box 72 can be fixed to the mounting frame 71. In particular, when the bonding pieces 73 in the storage box 72 are used up, the machine must be stopped first, then the storage box 72 is removed, and then a new storage box 72 (filled with bonding pieces 73) is loaded into the installation frame 71 and fixed, and then the bundling operation can be continued. It is worth noting that before installation, the threaded rod 74 must be controlled by the motor 711 to rotate so that the push plate 76 moves to the side away from the steel plate stack; like Figure 5 、 Figure 6 and Figure 8 As shown, the fitting mechanism 70 further includes a bracket fixed to one side of the outer wall of the mounting frame 71, on which an electric push rod 77 is fixed. An opening 78 is formed at one end of the mounting frame 71 to fit with the fitting member 73. A movable plate 79 is slidably connected to one side of the inner wall of the mounting frame 71 to fit with the opening 78. One end of the electric push rod 77 is connected to the movable plate 79. Specifically, when the front-end fitting 73 moves to the side of the cross-cutting steel plate stack under the push of the push plate 76, the fitting 73 is at the opening 78. In this state, the electric push rod 77 is started to move the movable plate 79 forward, thereby gradually pushing the fitting 73 to move slowly forward and gradually abut against the baffle 710. At this time, the part of the fitting 73 leaking out of the storage box 72 is larger than the width of the strapping steel belt. At the same time, the fitting 73 is still partially in the installation frame 71, and the baffle 710 is used to keep the fitting 73 in a vertical state. This state is as shown in FIG. Figure 8 As shown; In further detail, the laminating mechanism 70 further includes a horizontal plate fixed to the belt guide device 20, a U-shaped seat being fixed to the horizontal plate, a baffle 710 being rotatably connected to the U-shaped seat, and a torsion spring being sleeved on both ends of the baffle 710 and the U-shaped seat being rotatably connected, so that the baffle 710 can automatically reset to a vertical state after being driven forward by the laminating member 73, and a baffle bar for keeping the baffle 710 in a vertical state is fixed to one side of the upper surface of the U-shaped seat, so that the baffle 710 will not continue to rotate backward after being reset to the vertical state; Specifically, after the steel belt used for bundling is tightened, the cross-cut steel plate stack that has completed one bundling continues to move forward under the action of the conveying mechanism 10. During the movement, the tightened steel belt moves together with the fitting 73 inside it, gradually pushing the baffle 710 to rotate forward. When the tightened steel belt and fitting 73 are separated from the baffle 710, the baffle 710 rotates backward and returns to a vertical state under the action of the torsion spring. At this time, the motor 711 is started to make the push plate 76 push the fitting 73 in the storage box 72 to move, so that the next fitting 73 is against the side of the steel plate. At this time, the above-mentioned operation of pushing out the fitting 73 is repeated. Under the action of the fitting 73, the cross-cut steel plate stack can remain parallel during the continued movement and will not be offset.
[0020] like Figure 2 、 Figure 3 、 Figure 6 and Figure 8 As shown, the fitting member 73 includes two lower connecting seats 731, and the upper connecting seats 732 are slidably connected to the two lower connecting seats 731 through a first limiting sliding groove, and one end of one of the lower connecting seats 731 and one of the upper connecting seats 732 can be detachably fixed with a guide seat 733; One end of the guide seat 733 is semicircular. Specifically, during the tightening process of the steel belt, the inner wall of the steel belt corner gradually fits with one side of the semicircular shape of the guide seat 733, and after tightening, the corner is semicircular, which greatly reduces stress concentration. At the same time, after tightening, the upper and lower guide seats 733 are flush with the upper and lower surfaces of the steel plate stack, respectively, so that the steel belt can fit with the upper and lower surfaces of the cross-cutting steel plate. The edges of the outer walls of the other lower connecting seat 731, the other upper connecting seat 732 and the two guide seats 733 are inclined. Under the action of the inclined surface and the horizontal surface, the lower connecting seat 731, the upper connecting seat 732 and the guide seats 733 can drive the steel plate stack to maintain a horizontal state when they abut against the side surfaces of the cross-cutting steel plate stack, and will not deviate left or right. In further detail, in order to compensate for the tension of the steel strip, both sides of the outer wall of one of the lower connecting seats 731 and one of the upper connecting seats 732 are slidably connected with connecting rods 734 by providing second limiting sliding grooves, wherein two connecting rods 734 and one end of the other two connecting rods 734 are respectively connected to the other lower connecting seat 731 and the other upper connecting seat 732; A first spring 735 is installed on the bottom wall of the first limiting sliding groove, and the top of the first spring 735 is connected to the bottom end of the upper connecting seat 732. A second spring 736 is installed on the bottom of the outer wall of one of the lower connecting seats 731 and the top of the outer wall of one of the upper connecting seats 732. One end of the two sets of second springs 736 is connected to the other lower connecting seat 731 and the other upper connecting seat 732 respectively. Preferably, rubber gaskets are fixed at both ends of the first spring 735 and the second spring 736, and both ends of the first spring 735 and the second spring 736 are connected to the lower connecting seat 731 and the upper connecting seat 732 through rubber gaskets. Specifically, the elastic force generated by the compressed state of the second spring 736 is greater than the elastic force generated by the compressed state of the first spring 735. Under the action of the second spring 736, the two sets of lower connecting seats 731 and upper connecting seats 732 can move, thereby dynamically compensating the tension of the steel strip. Figure 2 Schematic diagram of the position between the connecting seats after the second spring 736 is fully compressed.
[0021] A method for operating an automatic bundling device for cross-cutting steel plate stacks comprises the following steps: S1. Before production, the bundling passes and bundling positions are set using a control system in a control cabinet with a touch screen. Then, during production, the cross-cut steel sheet stack travels through the conveyor mechanism 10 to the belt guide device 20, triggering a photoelectric sensor. Simultaneously, a precision encoder detects the travel distance of the cross-cut steel sheet stack. Once the stack reaches the set bundling position, the conveyor mechanism 10 stops. Next, the motor 711 is started to drive the threaded rod 74 to rotate, thereby driving the push plate 76 to push the fitting member 73 in the storage box 72 to move toward the cross-cutting steel plate, so that the front-end fitting member 73 abuts against the side of the cross-cutting steel plate. Then, after turning off the motor 711, the electric push rod 77 is started to cause the moving plate 79 to push the fitting member 73 forward until it abuts against the baffle 710. At this time, the fitting member 73 remains in this state and does not move. S2. Then, the tying head 40 is controlled to feed the steel belt along the belt guide device 20 to form a closed loop in the direction of the cross-section of the steel plate stack. At the same time, the position of the steel belt after the closed loop is adapted to the portion of the two fittings 73 exposed outside the mounting frame 71. Then, the six-axis robot 30 is started to carry the tying head 40 downward and press it on the steel plate stack, triggering the limit switch on the tying head 40. At this time, the tying head 40 retracts, tightens, locks, and cuts the belt, completing the tying operation. In the process of winding the belt, the inner wall of the steel belt gradually abuts against the outer wall of the fitting 73, and the semicircular end of the guide seat 733 drives the four corners of the tightened steel belt to turn into a semicircular shape; S3. After the bundling of this pass is completed, the six-axis robot 30 carrying the bundling head 40 automatically returns to the standby position, and then starts the conveying mechanism 10, continues to move across the steel plate stack, and reaches the next bundling position, repeating the above operation process to complete the bundling operation of all passes.
