Description

Technical Field

[0001] This invention relates to the field of packaging and printing equipment technology, specifically to a alignment and splicing device for a roll paper die-cutting machine. Background Technology

[0002] The packaging industry typically uses various die-cutting machines that feed paper from rolls. In existing die-cutting machines, when one roll of paper is used up and another roll is fed, it is necessary to manually splice the original roll with the new roll. For example, the existing patent CN 204938487 U discloses a non-stop zero-speed manual splicing device for offline rotary die-cutting production lines. The old paper strip is cut on the manual paper receiving table, and then the new and old paper strips are aligned and spliced. The aligned new and old paper strips are then firmly glued on both sides with tape to complete the splicing. Due to the high instability of manual operation, this manual splicing method is prone to large splicing errors. The spliced ​​paper strip needs to be fed for a long time to achieve accurate alignment. Each time the paper roll is changed for splicing, it will cause a large waste of paper. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a alignment and splicing device for a roll paper die-cutting machine, so as to solve the problem that the manual splicing of paper tape in the prior art has large errors and the spliced ​​paper tape needs to travel a long distance to complete accurate alignment, resulting in a large waste of paper.

[0004] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a roll paper die-cutting machine alignment and positioning splicing device is provided, including a frame, a main traction roller group set on the frame for traction of paper tape, a guide roller for guiding the paper tape, a left unwinding position and a right unwinding position for placing paper rolls, and also including a left auxiliary traction roller group set on the frame for auxiliary traction of the paper roll on the left unwinding position, a right auxiliary traction roller group set on the frame for auxiliary traction of the paper roll on the right unwinding position, a left fixing member, a right fixing member, a left detector, a right detector, a cutting member, and a controller;

[0005] The left fixing member is arranged opposite to the right fixing member. The left fixing member includes a horizontally arranged left connecting frame fixedly connected to the frame, a left fixing block slidably connected to the left connecting frame, and a left driving member that drives the left fixing block to slide horizontally. The left fixing block is provided with a left upper cavity and a left lower cavity that are both closed. An adsorption hole is provided on the vertical surface of the left fixing block near the right fixing member to connect the left upper cavity and the left lower cavity with the external space of the left fixing block. The left upper cavity and the left lower cavity are both connected to an external vacuuming device.

[0006] The right fixing component includes a horizontally arranged right connecting frame fixedly connected to the frame, a right fixing block slidably connected to the right connecting frame, and a right driving component for driving the right fixing block to slide horizontally. The right fixing block has a closed upper right cavity and a lower right cavity. The right fixing block is arranged opposite to the left fixing block. An adsorption hole is provided on the vertical surface of the right fixing block near the left fixing block, which connects the upper right cavity and the lower right cavity to the external space of the right fixing block. Both the upper right cavity and the lower right cavity are connected to an external vacuuming device.

[0007] The cutting component includes an inner connecting frame fixedly connected to the right fixed block, a knife holder slidably connected to the inner connecting frame, a cutting knife fixedly connected to the knife holder, a third driving component for driving the knife holder to slide on the inner connecting frame, a right knife slot for the cutting knife to pass through is provided in the right fixed block between the upper right cavity and the lower right cavity, and a left knife slot aligned with the right knife slot is provided in the left fixed block between the upper left cavity and the lower left cavity;

[0008] The controller is electrically connected to the left detector, the right detector, the main traction roller group, the left auxiliary traction roller group, and the right auxiliary traction roller group;

[0009] The left unwinding position is used to install the left paper roll, and the right unwinding position is used to install the right paper roll. Both the left paper tape that forms the left paper roll and the right paper tape that forms the right paper roll are provided with paper head marks and paper tail marks. The left detector is used to detect the paper head marks and paper tail marks on the left paper tape and send corresponding signals to the controller according to the detection results. The right detector is used to detect the paper head marks and paper tail marks on the right paper tape and send corresponding signals to the controller according to the detection results.

[0010] In the above configuration, the head and tail of the left paper strip on the left paper roll are correctly set with paper head marks and paper tail marks for detection and positioning by the left detector, respectively. The head and tail of the right paper strip on the right paper roll are correctly set with paper head marks and paper tail marks for detection and positioning by the right detector, respectively. The paper head marks and paper tail marks can be set as detection holes of different shapes or reflective stickers with different stripes, etc., which are detectable objects.

[0011] During a certain period, the left paper roll is used as the roll in operation, and the left paper strip is wound on the left paper roll. The right paper roll is used as a spare roll, and the right paper strip is wound on the right paper roll. When the left paper roll is working normally, the right paper strip on the spare paper roll is wound around the corresponding guide roller, passes between the left and right fixed blocks, and connects to the right auxiliary traction roller group. The right auxiliary traction roller group is run to pull the right paper roll and move the right paper strip upward. When the right detector detects the paper end mark on the right paper strip, the controller controls the right auxiliary traction roller group to stop running, and the right paper strip stops at the predetermined position and remains stationary.

[0012] When the main traction roller group finishes pulling the left paper tape release block on the left paper roll, the left detector detects the paper tail mark on the left paper tape. The controller controls the main traction roller group to stop running, and the left paper tape stops moving. At this time, the projections of the same patterns on the left and right paper tapes in the horizontal direction coincide. The left and right electric push rods are operated to bring the left and right fixed blocks closer together, pressing the left and right paper tapes together. The vacuum equipment is activated to evacuate the upper left cavity of the left fixed block, causing the left paper tape to adhere to the left fixed block. At the same time, the vacuum equipment is controlled to evacuate the lower right cavity of the right fixed block, causing the right paper tape to adhere to the right fixed block. Then, the third electric push rod is operated to push the knife holder to slide, causing the cutting knife to pass through the right knife slot and cut both the overlapping left and right paper tapes. Then, the third electric push rod is operated in reverse to cause the knife holder to drive the cutting knife to retract into the inner connecting frame. Then, the right electric push rod is operated in reverse again to cut the right paper tape. The fixing block retracts a certain distance, causing the lower section of the left paper tape to fall downwards. Simultaneously, the upper section of the right paper tape is removed. Then, the right electric push rod is operated to press the right fixing block firmly onto the left fixing block. At this point, the right paper tape on the right fixing block is pressed tightly against the side of the left fixing block corresponding to the lower left cavity. Next, the vacuuming of the lower right cavity of the right fixing block is stopped, and then the vacuuming of the lower left cavity of the left fixing block is performed, causing the right paper tape to be adsorbed onto the left fixing block. At this point, the upper section of the left paper tape and the right paper tape are precisely aligned on the side of the left fixing block. Thus, the upper section of the left paper tape and the right paper tape are both adsorbed onto the left fixing block and aligned. The right electric push rod is operated to move the right fixing block away from the left fixing block. The upper section of the left paper tape and the right paper tape are then glued together with tape to complete the splicing. The vacuuming equipment is turned off, and the main traction roller group is manually started to allow the right paper roll to release the right paper tape normally, achieving the purpose of splicing and changing the paper roll.

[0013] During the normal release of the right paper roll, a new left paper roll is replaced and the left auxiliary traction roller group is run. When the left detector detects the paper head mark on the left paper roll, the left auxiliary traction roller group stops, keeping the left paper roll stationary. When the release of the right paper roll is finished, when the right detector detects the paper tail mark on the right paper roll, the controller controls the main traction roller group to stop running. Then, the same method is used to precisely align and splice the upper section of the left paper roll and the right paper roll on the right fixed block and attach tape, so that the left paper roll can then release the left paper roll.

[0014] Furthermore, the left driving component is a left electric actuator, one end of which is fixedly connected to the left connecting frame, and the other end of which is fixedly connected to the left fixing block; the right driving component is a right electric actuator, one end of which is fixedly connected to the right connecting frame, and the other end of which is fixedly connected to the inner connecting frame; the third driving component includes a third electric actuator, one end of which is fixedly connected to the inner connecting frame, and the other end of which is fixedly connected to the tool holder; the left electric actuator, the right electric actuator, and the third electric actuator are all externally powered.

[0015] Furthermore, T-shaped sliding grooves are symmetrically arranged on both the left connecting frame and the right connecting frame. The T-shaped sliding grooves are horizontally arranged, and T-shaped sliders that cooperate with the T-shaped sliding grooves are respectively arranged on both sides of the left fixing block and both sides of the right fixing block.

[0016] Furthermore, the T-shaped slider on the left fixing block is integrally formed with the left fixing block, and the T-shaped slider on the right fixing block is integrally formed with the right fixing block.

[0017] Furthermore, the cutting edge of the cutting blade is inclined on the horizontal plane so that when the cutting blade cuts the stacked left and right paper tapes, each point of the cutting edge of the cutting blade contacts and cuts the left and right paper tapes in sequence, which increases the squeezing force of the cutting edge on the left and right paper tapes and helps to make the cut surfaces of the left and right paper tapes neat.

[0018] Furthermore, the upper left cavity, the lower left cavity, the upper right cavity, and the upper right cavity are all connected to an external vacuum pumping device via air tubes. Attached Figure Description

[0031] Combination Figure 1 , Figure 2As shown, the frame 10 is a gantry frame, and the left fixing member and the right fixing member are arranged opposite to each other.

An adsorption hole 40 is provided on the vertical surface of the left fixing block 206 near the right fixing member, which connects the upper left cavity 2061 and the lower left cavity 2062 with the external space of the left fixing block 206. The upper left cavity 2061 and the lower left cavity 2062 are both connected to an external vacuum device through an air pipe 62.

[0032] The right fixing component includes a horizontally arranged right connecting frame 305 fixedly connected to the frame 10, a right fixing block 306 slidably connected to the right connecting frame 305, and a right driving component that drives the right fixing block 306 to slide horizontally. The right fixing block 306 is provided with a closed upper right cavity 3061 and a lower right cavity 3062. An adsorption hole 40 is provided on the vertical surface of the right fixing block 306 near the left fixing component, which connects the upper right cavity 3061 and the lower right cavity 3062 with the external space of the right fixing block 306. The upper right cavity 3061 and the lower right cavity 3062 are both connected to an external vacuuming device through an air pipe 62.

[0033] like Figure 2 , Figure 4 As shown, the cutting component includes an inner connecting frame 501 fixedly connected to the right fixing block 306, a blade holder 502 slidably connected to the inner connecting frame 501, a cutting blade 503 fixedly connected to the blade holder 502, and a third driving member for driving the blade holder 502 to slide on the inner connecting frame 501. A right cutting slot 3063 is provided in the right fixing block 306 between the upper right cavity 3061 and the lower right cavity 3062, allowing the cutting blade 503 to pass through. A left cutting slot 2063 is provided in the left fixing block 206 between the upper left cavity 2061 and the lower left cavity 2062, aligned with the right cutting slot 3063.

[0034] The left connecting frame 205, the right connecting frame 305, and the inner connecting frame 501 are all horizontally placed U-shaped frames. The left driving component is a left electric actuator 207, one end of which is fixedly connected to the left connecting frame 205, and the other end of which is fixedly connected to the left fixing block 206. The right driving component is a right electric actuator 307, one end of which is fixedly connected to the right connecting frame 305, and the other end of which is fixedly connected to the inner connecting frame 501. The third driving component includes a third electric actuator 504, one end of which is fixedly connected to the inner connecting frame 501, and the other end of which is fixedly connected to the tool holder 502. The left electric actuator 207, the right electric actuator 307, and the third electric actuator 504 are all externally powered. Figure 3 As shown, T-shaped grooves 60 are symmetrically arranged on both the left connecting frame 205 and the right connecting frame 305. The T-shaped grooves 60 are horizontally arranged. T-shaped sliders 61 that cooperate with the T-shaped grooves 60 are integrally formed on both sides of the left fixing block 206 and both sides of the right fixing block 306.

[0035] like Figure 2 As shown, the cutting edge of the cutting blade 503 is inclined on the horizontal plane so that when the cutting blade 503 cuts the stacked left paper tape 202 and right paper tape 302, each point of the cutting edge of the cutting blade 503 contacts and cuts the left paper tape 202 and the right paper tape 302 in sequence, which increases the squeezing force of the cutting edge on the left paper tape 202 and the right paper tape 302, and helps to make the cut surfaces of the left paper tape 202 and the right paper tape 302 neat.

[0036] The controller is electrically connected to the left detector 204, the right detector 304, the main traction roller group 101, the left auxiliary traction roller group 203, and the right auxiliary traction roller group 303. Specifically, the left detector 204 and the right detector 304 can be configured as photoelectric scanning heads. The main traction roller group 101, the left auxiliary traction roller group 203, and the right auxiliary traction roller group 303 are all equipped with drive motors. The controller is electrically connected to each drive motor to control the operating status of each drive motor. The controller is also electrically connected to the left detector 204 and the right detector 304 to receive the detection signals from the left detector 204 and the right detector 304.

[0037] The left unwinding position 201 is used to install the left paper roll, and the right unwinding position 301 is used to install the right paper roll. The left paper strip 202 that forms the left paper roll and the right paper strip 302 that forms the right paper roll are both provided with paper head marks and paper tail marks.

[0038] The left detector 204 and the right detector 304 are both fixedly connected to the frame 10. The left detector 204 is located below the left auxiliary traction roller group 203, and the right detector 304 is located below the right auxiliary traction roller group 303. The left detector 204 is used to detect the paper head mark and paper tail mark on the left paper tape 202 and will send a corresponding signal to the controller according to the detection result. The right detector 304 is used to detect the paper head mark and paper tail mark on the right paper tape 302 and will send a corresponding signal to the controller according to the detection result.

[0039] The left paper tape 202 has correctly set paper head marks and paper tail marks for detection and positioning by the left detector 204 at its head and tail, respectively. Similarly, the right paper tape 302 has correctly set paper head marks and paper tail marks for detection and positioning by the right detector 304 at its head and tail, respectively. These paper head marks and paper tail marks can be set as detection holes or reflective stickers with stripe information, etc., making it possible for the left detector 204 to detect the paper tail mark on the left paper tape 202, or for the right detector 304 to detect the paper tail mark on the right paper tape 302. When the controller stops the main traction roller group 101 from rotating, when the left detector 204 detects the paper head mark on the left paper tape 202, the controller stops the left auxiliary traction roller group 203 from rotating. When the right detector 304 detects the paper head mark on the right paper tape 302, the controller stops the right auxiliary traction roller group 303 from rotating. When the left paper tape 202 and the right paper tape 302 are both stationary under the control of the controller, the projections of the same patterns on the left paper tape 202 and the right paper tape 302 in the horizontal direction coincide.

[0040] The working principle and beneficial effects of this solution are as follows:

[0041] During a certain period, the left paper roll is used as the roll in operation, with the left paper strip 202 wound on it. The right paper roll is used as a spare roll, with the right paper strip 302 wound on it. When the left paper roll releases the left paper strip 202 during normal operation, the right paper strip 302 on the spare right paper roll is wound around the corresponding guide roller 102 and then passes between the left fixed block 206 and the right fixed block 306 and is connected to the right auxiliary traction roller group 303. The right auxiliary traction roller group 303 is run to pull the right paper roll so that the right paper strip 302 moves upward. When the right detector 304 detects the paper head mark on the right paper strip 302, the controller controls the right auxiliary traction roller group 303 to stop running, and the right paper strip 302 stops at the predetermined position and remains stationary.

[0042] When the main traction roller group 101 is about to finish releasing the left paper tape 202 on the left paper roll, the left detector 204 detects the paper tail mark on the left paper tape 202. The controller then controls the main traction roller group 101 to stop running, and the left paper tape 202 stops moving. At this time, the projection of the same pattern on the left paper tape 202 and the right paper tape 302 in the horizontal direction coincides. Figure 4 As shown, operating the left electric actuator 207 and the right electric actuator 307 brings the left fixed block 206 and the right fixed block 306 closer together, pressing the left paper tape 202 and the right paper tape 302 together. The vacuum device is then activated to evacuate the upper left cavity 2061 of the left fixed block 206, causing the left paper tape 202 to adhere to the left fixed block 206. Simultaneously, the vacuum device is controlled to evacuate the lower right cavity 3062 of the right fixed block 306, causing the right paper tape 302 to adhere to the right fixed block 306. Next, the third electric actuator 504 pushes the blade holder 502 to slide, causing the cutting blade 503 to pass through the right blade slot 3063, stacking... The left paper tape 202 and the right paper tape 302, which are joined together, are both cut. Then, the third electric push rod 504 is reversed, causing the knife holder 502 to drive the cutting knife 503 back into the inner connecting frame 501. Next, the right electric push rod 307 is reversed again, causing the right fixing block 306 to move back a certain distance, causing the lower section of the left paper tape 202 to fall downwards. The upper section of the right paper tape 302 is then removed. Next, the right electric push rod 307 is reversed again, causing the right fixing block 306 to press firmly onto the left fixing block 206. At this time, the right paper tape 302 on the right fixing block 306 is pressed tightly against the side of the left fixing block 206 corresponding to the lower left cavity 2062 (e.g., Figure 5 (As shown), then stop evacuating the lower right cavity 3062 of the right fixing block 306, and then evacuate the lower left cavity 2062 of the left fixing block 206, so that the right paper tape 302 is attracted to the left fixing block 206. At this time, the upper section of the left paper tape 202 and the right paper tape 302 are precisely aligned on the side of the left fixing block 206. Thus, the upper section of the left paper tape 202 and the right paper tape 302 are both attracted to the left fixing block 206 and aligned. Run the right electric push rod 307 to move the right fixing block 306 away from the left fixing block 206. Use tape 63 to stick the upper section of the left paper tape 202 and the right paper tape 302 together to complete the splicing (as shown). Figure 6 (As shown), turn off the vacuum equipment and manually start the main traction roller group 101 to release the right paper roll 302 normally, so as to achieve the purpose of docking and splicing to replace the paper roll.

[0043] During the normal release of the right paper roll 302, a new left paper roll is replaced and the left auxiliary traction roller group 203 is run to pull the left paper roll 202. When the left detector 204 detects the paper head mark on the left paper roll 202, the controller controls the left auxiliary traction roller group 203 to stop rotating, so that the left paper roll 202 remains stationary. When the right paper roll is about to finish releasing, the right detector 304 detects the paper tail mark on the right paper roll 302, and the controller controls the main traction roller group 101 to stop running, so that the right paper roll 302 remains stationary. Then, the same method is used to precisely align and splice the upper sections of the left paper roll 202 and the right paper roll 302 on the right fixed block 306, and tape 63 is pasted at the joint of the left paper roll 202 and the right paper roll 302, so that the left paper roll can then release the left paper roll 202.

[0044] Compared with existing technologies that rely on manual cutting and splicing, the present invention has at least the following advantages:

[0045] 1. This device uses a photoelectric scanning head to control the alignment of the paper tapes to be connected, resulting in higher positioning accuracy and smaller errors in the spliced ​​paper tapes, effectively avoiding significant paper waste.

[0046] 2. When cutting the paper tape, press the two paper tapes to be spliced ​​together tightly and then cut the paper tape to effectively prevent the paper tape from shifting during the cutting process.

[0047] 3. By selecting the vacuum adsorption area, the portion of the paper tape that needs to be retained can be fixed, while the portion of the paper tape that needs to be discarded can move freely away from the device.

[0048] 4. Setting the cutter 503 on only one side of the paper tape is sufficient to meet the alignment cutting and splicing requirements in any situation. It is not necessary to set the cutter 503 on both sides of the paper tape, thus reducing the space occupied by the device.

[0049] The above are merely embodiments of the present invention, and common knowledge regarding specific structures and characteristics in the solutions is not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
