Description

Technical Field

[0001] This invention relates to the field of roll changing device technology, specifically a roll changing device for wide-format materials that can be used without stopping the machine. Background Technology

[0002] Multi-station rotary die-cutting machines, commonly known as circular die-cutting machines, use a rotating roller cutter for continuous die-cutting. They are among the most efficient die-cutting machines, and their products are widely used in mobile phones, computers, LCD displays, automobiles, medical devices, and new energy batteries.

[0003] In the existing technology, after the rotary die-cutting machine finishes feeding, the material strip needs to be replenished. The usual way to replenish it is to stop the machine and then replace the material strip. However, production cannot be carried out during the machine downtime, and after stopping and changing the roll, it is necessary to re-produce a new material strip of a certain length to ensure product accuracy, which wastes both time and material strip.

[0004] Currently, equipment or structures that allow for non-stop roll changing typically employ several methods for cutting strips, including circular blade rolling, serrated blade punching, and sliding blade cutting. Due to structural and dimensional limitations, some circular blade rolling or serrated blade punching methods are not effective for cutting very wide or thick strips, either due to low success rates or overly complex structures.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-8 The present invention provides a technical solution: a non-stop roll changing device for wide-format materials, including a frame 1, on which two symmetrically distributed first feeding shafts 21 and second feeding shafts 22 are arranged. The first feeding shafts 21 and second feeding shafts 22 are rotatably connected to the outside of the frame 1 through bearings. The first feeding shafts 21 and second feeding shafts 22 are respectively loaded with new rolls of material to be used (new material strip) and rolls of material currently being produced (old material strip). The frame 1 is equipped with a material strip positioning and cutting platform 4, an automatic tape applicator 5 and a material strip buffer mechanism 6 from bottom to top.

[0029] The strip positioning and cutting platform 4 includes a third rear receiving platform 43, a single-axis robot 44, a sliding cutter assembly 45, and a detection sensor 46. The system uses the detection sensor 46 to check if the strip is about to run out. The single-axis robot 44, the third rear receiving platform 43, and the detection sensor 46 are bolted to one side of the frame 1. The execution end of the single-axis robot 44 is bolted to the first front receiving platform 41 and the second front receiving platform 42, and it performs up-and-down reciprocating motion. The third rear receiving platform 43 is on the same horizontal plane as the first front receiving platform 41 and the second front receiving platform 42, and a slide gap 47 is reserved between the three. The sliding cutter assembly 45 is bolted to one side of the frame 1 and faces the slide gap 47, automatically... The tape application mechanism 5 includes a first servo motor 51 and a second servo motor 52. The first servo motor 51 and the second servo motor 52 are bolted to one side of the frame 1. The power end of the first servo motor 51 is fixedly connected to a first reducer 53 via a coupling. The output end of the first reducer 53 is bolted to a front-facing tape application suction cup 54. The power end of the second servo motor 52 is fixedly connected to a second reducer 55 via a coupling. The output end of the second reducer 55 is bolted to a back-facing tape application suction cup 56. The tape buffer mechanism 6 includes a third servo motor 61, a proximity sensor 614, and a fourth servo motor 614. The third servo motor 61 is bolted to the inside of the frame 1. A third reducer 62 is fixedly connected to the power end of machine 61 via a coupling. A gear 63 is fixedly connected to the output end of the third reducer 62 via bolts. A rack 64 is meshed with the lower side of the gear 63. A mounting base 65 is slidably connected to the lower inner side of the rack 64 with clearance fit. The mounting base 65 is fixedly connected to the inside of the frame 1 via bolts. Several sets of pulleys 66 are rotatably connected to the upper part of the frame 1 via bearings. A belt 67 is sleeved on the outer side of the pulleys 66. One end of the belt 67 is fixedly connected to the rack 64 via bolts. A sliding plate 68 is fixedly connected to the other side of the belt 67 via bolts. A linear guide rail 69 is slidably connected to the inner side of one end of the sliding plate 68 with clearance fit. The linear guide rail 69 is fixedly connected to the outside of the frame 1 via bolts. The third servo motor 61 drives the gear 63 and rack 64. 4. The movement controls the sliding plate 68. Two sets of material belt guide shafts 610 are rotatably connected to the other end of the sliding plate 68 via bearings. A certain length of material belt can be buffered between the guide shaft 3 fixed on the frame 1 and the material belt guide shafts 610 on the sliding plate 68. A fourth servo motor 611 is bolted to the inside of the frame 1. A fourth reducer 612 is fixedly connected to the power end of the fourth servo motor 611 via a coupling. The power end of the fourth reducer 612 penetrates the frame 1 and is bolted to a material belt traction roller group 613. The fourth servo motor 611 is connected to the material belt traction roller group 613. By driving the rotation of the material belt traction roller group 613, the movement and stopping of the material belt are controlled. A proximity sensor 614 is bolted to the outside of the frame 1.The system detects the position of the sliding plate 68 using a proximity sensor 614 to determine the current buffer status of the material strip. When the sliding plate 68 moves away from the guide shaft 3 fixed on the frame 1, it increases the buffer of the material strip; conversely, it consumes the buffer. During the automatic cutting and bonding of the material strip, by consuming the buffered material strip, the rotary die-cutting machine can achieve uninterrupted production in subsequent processes.

[0030] The sliding cutter assembly 45 includes a rodless cylinder 451. The actuator of the rodless cylinder 451 is fixedly connected to a blade holder 452 by bolts. A blade 453 is embedded in the inner side of the blade holder 452. The blade 453 can reciprocate along the slide gap 47 to cut the material strip.

[0031] The first front receiving platform 41, the second front receiving platform 42 and the third rear receiving platform 43 are all composed of a receiving plate 431, a material strip width limiting adjustment device 432, a pressing device 433 and a negative pressure adsorption area 434. The surface of the receiving plate 431 is engraved with a scale 435.

[0032] The material strip width limiting adjustment device 432 includes a connecting frame 4321, which is fixedly connected to the lower part of one side of the receiving platform 431 by bolts. A threaded rod 4322 is rotatably connected inside the connecting frame 4321 through a bearing. Two sets of limiting plates 4323 are threadedly connected to the outside of the threaded rod 4322. A sliding groove 4324 is opened on the upper part of the receiving platform 431, which is directly opposite to the connecting frame 4321. The limiting plates 4323 are slidably connected to the sliding groove 4324 with clearance fit. By adjusting the threaded rod 4322, the limiting plates 4323 on both sides can be moved in opposite directions along the sliding groove 4324, thereby adjusting the position of the limiting plates 4323 on both sides according to the width of the material strip.

[0033] The pressing device 433 includes a hydraulic cylinder 4331, which is fixedly connected to the lower middle part of the receiving platform 431 by bolts. The output end of the hydraulic cylinder 4331 is fixedly connected to a lifting plate 4332 by bolts. A lifting rod 4333 is welded and fixedly connected to the upper side of the lifting plate 4332. The upper part of the lifting rod 4333 penetrates the receiving platform 431 and is fixedly connected to a pressing frame 4334 by bolts. A pressing block 4335 is fixedly connected inside the pressing frame 4334 by adhesive. The hydraulic cylinder 4331 pushes the lifting plate 4332 downward, which in turn drives the pressing frame 4334 and the lower pressing block 4335 downward through the lifting rod 4333 to fix the material strip.

[0034] The negative pressure adsorption zone 434 includes an adsorption box 4341, which is fixedly connected to the lower side of the receiving platform 431 by bolts. The receiving platform 431 has a vent 4342 that communicates with the adsorption box 4341. The adsorption box 4341 generates negative pressure, and the vent 4342 adsorbs and fixes the end of the material strip.

[0035] The front-facing tape-applying suction cup 54 has a suction cup guide rail 541 and a suction cup buffer post 542 on one side. The front-facing tape-applying suction cup 54 is slidably connected to the inside of the suction cup guide rail 541 by a slider. The front-facing tape-applying suction cup 54 can be pulled out along the suction cup guide rail 541, making it convenient for the operator to adsorb the tape onto it. The suction cup buffer post 542 is an elastic telescopic structure. The suction cup buffer post 542 can effectively buffer the suction cup to a certain extent during the front-facing tape-applying process, and better adhere the tape to the material belt during the buffering process, ensuring the tape-applying effect.

[0036] The material belt traction roller assembly 613 includes an outer mounting frame 6131, which is fixedly connected to the outside of the frame 1 by bolts. A first traction roller 6132 is rotatably connected to one end of the outer mounting frame 6131 via a bearing. The other end of the first traction roller 6132 is fixedly connected to the output end of the fourth reducer 612 by bolts. Two sets of clamping cylinders 6133 are fixedly connected to the outside of the outer mounting frame 6131 by bolts. The output end of the clamping cylinder 6133 penetrates the outer mounting frame 6131 and is fixedly connected to an inner mounting frame 6134 by bolts. A second traction roller 6135 is rotatably connected to the inside of the inner mounting frame 6134 via a bearing. The gap between the material belt traction roller assembly 613 and the material belt is adjusted by the clamping cylinders 6133 to accommodate material belts of different thicknesses, thereby controlling the pressure between the material belt traction roller assembly 613 and the material belt.

[0037] A tape length cutter 7 is bolted to one side of the frame 1. An operation panel 8 is provided at the front of the tape length cutter 7 for taking out a certain length of tape.

[0038] Working principle: When using this invention, the new material strip is loaded onto the first feeding shaft 21 (or the second feeding shaft 22). Then, the end of the new material strip is pulled to pass through several guide shafts 3 applicable to the first feeding shaft 21. The operator aligns the new material strip with the old material strip by referring to the scale 435 on the first front receiving platform 41 (or the second front receiving platform 42). The end of the new material strip is then fixed by the pressing device 433 on the first front receiving platform 41 (or the second front receiving platform 42). The old material strip is currently on the second feeding shaft 22 and passes through several guide shafts 3 applicable to the second feeding shaft 22, the second front receiving platform 42, the third rear receiving platform 43, and the material strip buffer mechanism 6 in sequence before entering the circular die-cutting machine for the subsequent process.

[0039] The operator uses the tape cutter 7 to take a certain length of tape, pulls the front tape suction cup 54 along the suction cup slide rail 541, and pre-attaches the tape to the front tape suction cup 54 and the back tape suction cup 56 respectively.

[0040] When the detection sensor 46 detects that the current material strip is about to finish unwinding, the fourth servo motor 611 of the material strip buffer mechanism 6 stops rotating, causing the material strip traction roller group 613 to stop traction of the material strip. At the same time, the pressing device 433 on the second front receiving platform 42 and the third rear receiving platform 43 presses down the current material strip. Simultaneously, the negative pressure adsorption area 434 on the second front receiving platform 42 and the third rear receiving platform 43 activates vacuum to adsorb and fix the material strip respectively. The negative pressure adsorption area 434 on the first front receiving platform 41 activates vacuum to adsorb and fix the end of the new material strip. At this time, the rotary die-cutting machine of the subsequent process continues to produce normally, consuming the material strip that has been buffered on the material strip buffer mechanism 6 for a certain length.

[0041] Then, the blade 453 on the sliding cutter assembly 45 slides outward from the initial inner position along the slide gap 47, cuts the material strip, and then slides back to the initial inner position.

[0042] Then, the single-axis robot 44 drives the first front receiving platform 41 to move downward (or upward) to the same height as the third rear receiving platform 43; the second front receiving platform 42 is in the position of waiting to replace the material roll, the negative pressure adsorption area 434 of the second front receiving platform 42 breaks the vacuum, waiting for the old roll tail to be removed by the manual, and is ready to replace the new roll on the second feeding shaft 22.

[0043] Then, the first servo motor 51 drives the front tape application suction cup 54 to rotate at a certain angle, applying the front tape to the joint between the new and old tapes. Then, the first servo motor 51 drives the front tape application suction cup 54 to rotate back to the initial position. The operator pre-attaches the tape to the front tape application suction cup 54 and waits for the next tape application action.

[0044] Then, the pressing devices 433 on the first front receiving platform 41 and the third rear receiving platform 43 are lifted. At the same time, the vacuum in the negative pressure adsorption zone 434 on the first front receiving platform 41 and the third rear receiving platform 43 is broken. The fourth servo motor 611 of the material belt buffer mechanism 6 drives the material belt traction roller group 613 to start rotating, pulling the material belt forward. After the material belt has passed a certain length, the material belt docking joint moves to the set position. The second servo motor 52 drives the back adhesive tape suction cup 56 to start rotating, rolling the back adhesive tape onto the back of the docking joint of the new material belt and the old material belt. At this time, the two-sided adhesive tape application action of the new material belt is completed. The second servo motor 52 drives the back adhesive tape suction cup 56 to return to the initial position. The operator pre-adheres the tape onto the back adhesive tape suction cup 56, waiting for the next tape application action.

[0045] Meanwhile, the third servo motor 61 of the material belt buffer mechanism 6 drives the gear 63 and rack 64 to move through torque mode control, applying a certain external force to the sliding plate 68 connected to the rack 64, thereby providing tension for the material belt in the buffer area to enter the subsequent process of the rotary die-cutting machine. The fourth servo motor 611 drives the material belt traction roller group 613 to continue rotating, traction the material belt at a certain speed, and matches the speed of the rotary die-cutting machine in the subsequent process. The system calculates the compensation value by controlling the speed difference between the traction feeding speed of the material belt traction roller group 613 and the production speed of the rotary die-cutting machine, and buffers the material belt to a certain length.
