Description

Technical Field

[0001] This utility model relates to the field of tape manufacturing machinery technology, and in particular to a fully automatic tape rewinding machine. Background Technology

[0002] The production of adhesive tape includes two processes: rewinding and roll-to-label. Rewinding is completed on a rewinding device, while roll-to-label is done manually. The rewinding device applies adhesive tape to the paper roll for rewinding. The roll-to-label process involves pulling and tightening the rewound tape roll and then affixing a sealing label to the opening. In the existing technology, the rewinding device and the roll-to-label process are independent equipment and processes. After rewinding, the rewound tape roll is manually transferred to the roll-to-label process for pulling, tightening, and labeling. From the rewinding to the roll-to-label process, the tape roll must undergo at least one manual transfer, which not only requires a large amount of manpower but also results in low production efficiency. Therefore, we propose a fully automatic tape rewinding machine. Summary of the Invention

[0033] The operator inserts the middle of the tape roll to be rewound onto the tape roll fixing shaft 201b, and controls the PLC controller to control the first rotating motor 201e to rotate at a set speed. The first rotating motor 201e drives the second synchronous pulley 201f to rotate, which in turn drives the first synchronous pulley 201c to rotate via the synchronous belt. The rotation of the first synchronous pulley 201c drives the tape roll 600 on the tape roll fixing shaft 201b to rotate via the reducer 201a. The tape on the tape roll passes sequentially through the first first rotating roller 201g on the end face of the support plate 102, the second rotating roller 201j on the end face of the sliding block 201i, and the second first rotating roller 201g on the end face of the support plate 102.

[0034] In this embodiment, the first feeding component 202 includes a synchronous belt module S disposed at the top of the first support platform 103. An L-shaped mounting bracket 202a is disposed at the top of the slider of the synchronous belt module S. A second rotating motor 202c is disposed on the back of the L-shaped mounting bracket 202a via a first motor bracket 202b. A third synchronous pulley 202d is connected to the output end of the second rotating motor 202c. A third rotating roller 202e is rotatably disposed on the front of the L-shaped mounting bracket 202a. A first mounting frame 202f is fixedly disposed on one side of the third rotating roller 202e. A first extrusion roller 202g is rotatably disposed between the first mounting frame 202f and the L-shaped mounting bracket 202a. One end of wheel 202g passes through L-shaped mounting bracket 202a and is provided with a fourth synchronous belt pulley 202h. The fourth synchronous belt pulley 202h and the third synchronous belt pulley 202d are driven by a synchronous belt. A first cylinder 202i is provided on one side of the first mounting frame 202f through a cylinder seat. A fixing block 202i-1 is provided at the end of the telescopic rod of the first cylinder 202i. A second mounting frame 202j is fixed on one side of the fixing block 202i-1. A second extrusion wheel 202j-1 located directly below the first extrusion wheel 202g is rotatably arranged in the second mounting frame 202j. The second rotating motor 202c and the first cylinder 202i are electrically connected to the PLC controller.

[0035] The operator controls the telescopic rod of the first cylinder 202i to retract via the PLC controller, causing the first extrusion roller 202g and the second extrusion roller 202j-1 to separate. One end of the tape is then placed on the outer wall of the third rotating roller 202e and passes between the first extrusion roller 202g and the second extrusion roller 202j-1. At this time, the telescopic rod of the first cylinder 202i is extended, causing the first extrusion roller 202g and the second extrusion roller 202j-1 to come together and clamp the tape. After the second rotating motor 202c is turned on, the second rotating motor 202c drives the third synchronous pulley 202d to rotate. The three synchronous pulleys 202d drive the fourth synchronous pulley 202h to rotate via the synchronous belt. The fourth synchronous pulley 202h drives the first extrusion wheel 202g to rotate, thus providing transmission power to the belt. The synchronous belt module S is a mature existing device on the market (its principle will not be elaborated here). A synchronous belt motor is set on one side of the synchronous belt module S. The synchronous belt motor is electrically connected to the PLC controller. The PLC controller controls the forward and reverse rotation of the synchronous belt motor, which can drive the slider on the synchronous belt module S to move linearly along the length of the synchronous belt module S, thereby driving the L-shaped mounting bracket 202a to move.

[0036] In this embodiment, a support plate 202k is provided on one side of the first mounting frame 202f, and elongated mounting blocks 202k-1 are provided on both sides of the top of the support plate 202k.

A roller-type meter counter 202l electrically connected to the PLC controller is provided at the top of the L-shaped mounting frame 202a. The roller of the roller-type meter counter 202l is movably engaged with the outer wall of the third rotating roller 202e. A first mounting plate 202m is provided on one side of the back of the L-shaped mounting frame 202a, and a second cylinder 202n is provided on the first mounting plate 202m. The second cylinder 202n has a first limiting guide rail at its top and a first sliding plate 202n-2 above it. The bottom of the first sliding plate 202n-2 is slidably engaged with the first limiting guide rail. The end of the telescopic rod of the second cylinder 202n is connected to the end of the first sliding plate 202n-2. A connecting plate 202n-3 is fixedly connected to the side of the first sliding plate 202n-2. A connecting block 202n-4 is provided on one side of the connecting plate 202n-3. A first pneumatic scissor 202n-6 is provided at the top of the connecting block 202n-4 through a second mounting plate 202n-5. The second cylinder 202n is electrically connected to the PLC controller.

[0037] The conveyor belt, passing between the first extrusion roller 202g and the second extrusion roller 202j-1, is placed on the top of the pallet 202k and passes through the limiting plate 202k-2 and the limiting roller 202k-3. During conveyor belt transport, because the roller of the roller-type meter counter 202l is in movable engagement with the outer wall of the third rotating roller 202e, the conveyor belt also drives the roller of the roller-type meter counter 202l to rotate. The roller-type meter counter 202l can be set by a PLC controller. When the roller on the roller-type meter counter 202l calculates the set distance, the roller-type meter counter... 202l sends a signal to the PLC controller, which can control the extension rod of the second cylinder 202n to extend. The first pneumatic scissors 202n-6 on the second mounting plate 202n-5 can be switched on and off with an external air source through a solenoid valve electrically connected to the PLC controller. Therefore, the PLC controller can control the air supply of the first pneumatic scissors 202n-6 to perform cutting operations. When the extension rod of the second cylinder 202n drives the first sliding plate 202n-2 to move forward, the first pneumatic scissors 202n-6 is controlled to cut the tape.

[0038] In this embodiment, the rewinding assembly 303 includes a synchronous belt module S disposed at the top of the fifth support platform 302. The top of the slider of the synchronous belt module S is provided with a base plate 303a. A transmission seat 303b and a mounting seat 303c are respectively disposed on one side of the top of the base plate 303a. A third rotary motor 303d is disposed on the mounting seat 303c through a second motor bracket 303c-1. The output end of the third rotary motor 303d is connected to a fifth synchronous pulley 303d-1. An air shaft 303e is rotatably disposed on the transmission seat 303b. One end of the air shaft 303e is connected to a sixth synchronous pulley 303e-1. The fifth synchronous pulley 303d-1 and the sixth synchronous pulley 303e-1 are driven by a synchronous belt. The third rotary motor 303d is electrically connected to a PLC controller.

[0039] The PLC controller activates the third rotary motor 303d, which drives the fifth synchronous pulley 303d-1 to rotate. The fifth synchronous pulley 303d-1, via a synchronous belt, drives the sixth synchronous pulley 303e-1 to rotate. The sixth synchronous pulley 303e-1, in turn, drives the air shaft 303e to rotate. One end of the air shaft 303e is connected to an external air source via a rotary joint, and the air source is controlled by a solenoid valve electrically connected to the PLC controller. Therefore, the PLC controller can control the corresponding solenoid valve to control the inflation and deflation of the air shaft 303e. When the air shaft 303e is inflated, the key bar on the air shaft 303e protrudes from its surface and can be squeezed... The paper tube is fitted onto the air shaft 303e. When the air shaft 303e rotates, it can drive the paper tube to rotate and rewind the tape. The synchronous belt module S here is the same as the above, and they are all mature existing devices on the market, so they will not be described in detail here. The PLC controller controls the synchronous belt motor on the synchronous belt module S, which in turn drives the slider of the synchronous belt module S to move along the length direction of the synchronous belt module S. When the slider moves forward, it can drive the uninflated air shaft 303e to insert into the paper tube. Then, after the air shaft 303e is inflated and clamps the paper tube, the air shaft 303e rotates and drives the paper tube to rewind the tape. After the rewinding is completed, the air shaft 303e deflates and releases the paper tube. Then the slider moves backward, causing the paper tube to disengage from the air shaft 303e.

The end of the telescopic rod of the ninth cylinder 402h is connected to the sixth sliding plate 402i. An elastic pressure plate 402j is provided on the side wall of the sixth sliding plate 402i. The front end of the elastic pressure plate 402j is bent obliquely upward. The eighth cylinder 402b and the ninth cylinder 402h are electrically connected to the PLC controller.

[0041] The synchronous belt module S here is the same as described above; it is a mature, existing device on the market and will not be elaborated further. The PLC controller controls the synchronous belt motor on the synchronous belt module S, thereby driving the slider of the synchronous belt module S to move along the length of the synchronous belt module S. Since the label adsorption block 402e has a hollow internal structure, the label adsorption block 402e controls the air supply to and from the external air source through a solenoid valve electrically connected to the PLC controller. Therefore, the PLC controller can control the corresponding solenoid valve to control the vacuuming operation inside the label adsorption block 402e. After the extension rod of the eighth cylinder 402b extends, it drives the label adsorption block 402e to move down and adsorb the label. Then, the extension rod of the eighth cylinder 402b is controlled to retract, driving the label adsorption block 402e to move up. As the air expansion shaft 303e drives the paper tube to rewind the tape, the PLC controller controls the extension rod of the ninth cylinder 402h to extend the tape. The sixth sliding plate 402i and the elastic pressure plate 402j move forward. The elastic pressure plate 402j can press down the tape roll with its diameter continuously increasing, preventing the tape roll from loosening and making it easier to apply labels. The front end of the elastic pressure plate 402j is bent upwards to facilitate better insertion of the elastic pressure plate 402j above the rewound tape roll. Then, when the slider of the synchronous belt module S moves to the left, it drives the eighth cylinder 402b to move to the left as well. When the eighth cylinder 402b moves to the set position, the telescopic rod of the eighth cylinder 402b is controlled to extend, causing the label adsorption block 402e to move downwards, so that the adhesive surface of the label adsorbed by the label adsorption block 402e is stuck between the end of the tape and the surface of the tape loop. At this time, the PLC controller controls the label adsorption block 402e to stop the vacuuming operation. Then, the telescopic rod of the eighth cylinder 402b retracts, causing the label adsorption block 402e to move upwards. The slider of the synchronous belt module S also drives the eighth cylinder 402b back to its original position for the next label adsorption.

[0045] In this embodiment, the second feeding assembly 304 includes a cylinder mounting bracket 304a, a rodless cylinder 304b is mounted on one side of the cylinder mounting bracket 304a, a push-pull block 304c-1 is provided at the top of the sliding block 304c of the rodless cylinder 304b, a first pneumatic gripper 304d is fixed at the end of the push-pull block 304c-1, a baffle 304e is provided at the position corresponding to the paper tube feeding track 301 on the side wall of the sixth mounting plate 402f, a twelfth cylinder 304f is provided at the position corresponding to the bottom of the second horizontal plate 402g, and a stop block 304f-1 is provided at the end of the telescopic rod of the twelfth cylinder 304f. The rodless cylinder 304b and the twelfth cylinder 304f are electrically connected to the PLC controller.

[0046] When paper tubes are needed, the PLC controller can control the extension rod of the twelfth cylinder 304f to retract, causing the stop block 304f-1 to move out of the paper tube feeding track 301. The paper tubes in the paper tube feeding track 301 enter the clamping jaws of the first pneumatic gripper 304d. Then, the extension rod of the twelfth cylinder 304f extends, causing the stop block 304f-1 to move into the paper tube feeding track 301 and stop the paper tube from moving forward. The first pneumatic gripper 304d communicates with the external system via a solenoid valve electrically connected to the PLC controller. When the air supply is switched on and off, the PLC controller can control the corresponding solenoid valve to control the first pneumatic gripper 304d to clamp the paper tube, and control the sliding block 304c on the rodless cylinder 304b to move forward to a specific position. At this position, after the paper tube in the clamping jaw of the first pneumatic gripper 304d is clamped by the air shaft 303e, the PLC controller controls the first pneumatic gripper 304d to open, and then controls the sliding block 304c on the rodless cylinder 304b to drive the first pneumatic gripper 304d to return to its original position.

[0047] In this embodiment, the discharge mechanism 500 further includes a color sensor 507a mounted on the end face of the support plate 102 via a seventh mounting plate 507, and a dropping frame 508 mounted on one end of the belt support block 503. Two symmetrically inclined clamping plates 508a are fixed to the top of the dropping frame 508. An eighth mounting plate 508b is mounted on one side of the dropping frame 508. A tenth cylinder 508c is mounted at the top of the eighth mounting plate 508b. A blocking plate 508d is connected to the end of the telescopic rod of the tenth cylinder 508c. An eleventh cylinder is mounted on the outer wall of the belt roller mounting plate 504 at the other end of the belt support block 503 via a cylinder seat.

[0048] When there is damage on the tape roll, two lines can be drawn with a marker to indicate the damaged section between the two lines. During tape conveying on the tape roll, the tape distance for each paper roll rewinding is set. During the rewinding operation, when the two lines pass color sensor 507a, there are three situations requiring rejection of defective products. First, if the first line passes color sensor 507a before the second line passes it before the tape stops, the finished product rewound from the first line is considered defective. The eleventh cylinder 509 can be set by the PLC controller to extend its telescopic rod at a specific time (since the entire tape rewinding process takes a fixed time, the extension time of the eleventh cylinder 509 telescopic rod is adjustable). The telescopic rod will push the rewound tape roll transported to the opposite side of the eleventh cylinder 509 off the belt 506 as defective. Second, if the section between the first and second lines is rewound as a finished product, then this... Some finished products must be rejected, and the rejection time is also set by the PLC controller; the third case: when the second line passes the color sensor 507a, the finished products of the second line must be rejected, and the rejection time is also set by the PLC controller. When the paper tube rewinding ends, the servo motor 501 rotates, which drives the clamping jaw of the second pneumatic gripper 501b to rotate to the finished product. The second pneumatic gripper 501b is connected to the external air source through a solenoid valve electrically connected to the PLC controller. Therefore, the PLC controller can control the second pneumatic gripper 501b to clamp the finished product at this time. Then the servo motor 501 rotates in the opposite direction, so that the finished product is placed between the two clamping plates 508a. Then the servo motor 501 rotates in the opposite direction to the original position. Then the tenth cylinder 508c retracts the telescopic rod, which drives the blocking plate 508d to move towards the finished product and pushes the finished product onto the belt 506. The belt 506 is driven to rotate by the belt roller 505, which is driven to rotate by the fourth rotating motor 510a.

[0049] Working principle: The operator inserts the middle of the tape roll onto the tape roll fixing shaft 201b. The tape on the tape roll passes sequentially through the first first rotating roller 201g on the end face of the support plate 102, the second rotating roller 201j on the end face of the sliding block 201i, the second first rotating roller 201g on the end face of the support plate 102, between the first extrusion roller 202g and the second extrusion roller 202j-1, and onto the pallet 202k. The first rotating motor 201e drives the tape roll on the tape roll fixing shaft 201b to rotate at a set speed to feed the tape. The PLC controller controls the extension rod of the twelfth cylinder 304f to retract, driving the stop block 304f-1 to move out of the paper tube feeding track 301. The paper tube in the paper tube feeding track 301 enters the first cylinder... At the clamping jaw of the moving gripper 304d, the extension rod of the twelfth cylinder 304f extends, causing the stop block 304f-1 to move into the paper tube feeding track 301 and abut against the paper tube. Therefore, the PLC controller can control the first pneumatic gripper 304d to clamp the paper tube at the clamping jaw, and control the sliding block 304c on the rodless cylinder 304b to move forward to the position corresponding to the clamping jaw of the first pneumatic gripper 304d and the air shaft 303e. Then, it controls the synchronous belt module S at the top of the fifth support platform 302 to slide forward, causing the air shaft 303e to insert into the paper tube. At this time, the air shaft 303e inflates, and the key strip protrusion on the surface of the air shaft 303e fixes the paper tube. At this time, the second rotating motor 202c is activated for a specific time period, causing the second rotating motor 202c to rotate briefly. Temporarily, the second rotating motor 202c drives the first extrusion roller 202g to move the tape forward a certain distance. Then, it controls the slider in the synchronous belt module S at the top of the first support platform 103 to move to the right. Since the tape is held by the first extrusion roller 202g and the second extrusion roller 202j-1, it moves the entire tape to the right until one end of the tape is above the paper tube. Then, the tape pasting assembly 401 uses transparent tape to stick and fix one end of the tape to the outer wall of the paper tube. The working process of the tape pasting assembly 401 is to insert the transparent tape roll onto the transparent tape roll fixing shaft 401e-4, and stretch one end of the transparent tape around the two tape guide rollers 401e-5 and place it between the concave block 401d-1 and the extrusion block 401d-3. The fourth cylinder 40 is then controlled. The telescopic rod of 1d-2 extends, causing the extrusion block 401d-3 and the concave block 401d-1 to clamp the transparent tape. Then, the telescopic rod of the third cylinder 401b extends, moving the extrusion block 401d-3 and the concave block 401d-1 forward. Simultaneously, the telescopic rod of the sixth cylinder 401f-1 on the support cabinet 401f extends, causing the elongated pressing block 401f-3 to pass through the notch in the middle of the concave block 401d-1 and abut against the top of the extrusion block 401d-3. At this point, the transparent tape is also pressed down by the bottom of the elongated pressing block 401f-3. Since the elongated pressing block 401f-3 has a vacuum structure, it is connected to an external air source through a solenoid valve electrically connected to the PLC controller.Therefore, the PLC controller controls the elongated pressing block 401f-3 to create a vacuum inside, causing the vacuum hole at the bottom of the block to adhere to the transparent tape. At this point, the extension rod of the fourth cylinder 401d-2 shortens, separating the pressing block 401d-3 from the concave block 401d-1. Next, the extension rod of the third cylinder 401b retracts, moving the pressing block 401d-3 and the concave block 401d-1 back to their original positions. Then, the extension rod of the fourth cylinder 401d-2 extends, allowing the pressing block 401d-3 and the concave block 401d-1 to continue clamping the transparent tape. Finally, the extension rod of the fifth cylinder 401e-6 extends, moving the second pneumatic scissors 401e-8 to the transparent tape. Subsequently, the PLC controller controls the second pneumatic scissors 401e-8 to cut the transparent tape. Then, the sixth cylinder 401f-1 drives the elongated pressing block 401f-3 to continue moving downwards, pressing the bottom of the transparent tape between the paper tube and the tape end. At this time, the end of the telescopic rod of the seventh cylinder 401f-5 extends, causing the arc-shaped block 401f-6 to move downwards and squeeze the transparent tape, ensuring it is firmly adhered. After the paper tube and one end of the tape are fixed with transparent tape, the third rotary motor 303d is turned on, driving the air shaft 303e to rotate. Since the rewinding length of the paper tube is set, the roller-type meter counter 202l can calculate the rewinding length, and thus send a signal to the PLC controller. The PLC controller controls the rotation of the third rotary motor 303d. As the air shaft 303e rotates, the PLC controller controls the extension rod of the ninth cylinder 402h to extend, driving the sixth sliding plate 402i and the elastic pressure plate 402j forward. The elastic pressure plate 402j can press down the tape roll with its continuously increasing diameter to prevent the tape roll from loosening. At this time, the label pasting component 402 can paste the label. The working process of the label pasting component 402 is as follows: the PLC controller controls the slider in the synchronous belt module S on the top side wall of the fourth support platform 106 to move along the length direction of the synchronous belt module S. Since the label adsorption block 402e has a hollow internal structure, the label adsorption block 402e is controlled by a solenoid valve electrically connected to the PLC controller. The system controls the connection and disconnection of the external air source, so the PLC controller can control the label adsorption block 402e to perform a vacuum operation. After the extension rod of the eighth cylinder 402b extends, it moves the label adsorption block 402e downward to adsorb the label. Then, the extension rod of the eighth cylinder 402b is controlled to retract, moving the label adsorption block 402e upward. Then, when the PLC controller controls the slider in the synchronous belt module S to move to the left, it also moves the eighth cylinder 402b to the left. When the eighth cylinder 402b moves directly above the paper tube, the extension rod of the eighth cylinder 402b is controlled to extend, moving the label adsorption block 402e downward, so that the adhesive side of the label adsorbed by the label adsorption block 402e is pasted between the end of the tape and the surface of the tape loop. At this time, a complete tape rewinding and label pasting operation is completed.The servo motor 501 rotates, causing the jaws of the second pneumatic gripper 501b to rotate to the finished product position. The second pneumatic gripper 501b, via a solenoid valve electrically connected to the PLC controller, controls the air supply to and from the external air source. Therefore, the PLC controller can control the second pneumatic gripper 501b to clamp the finished product. Then, the servo motor 501 rotates in the reverse direction, placing the finished product held by the second pneumatic gripper 501b between the two clamping plates 508a and releasing the gripper. Next, the servo motor 501 rotates in the reverse direction to its original position. Subsequently, the tenth cylinder 508c retracts its telescopic rod, moving the blocking plate 508d towards the finished product and pushing it onto the belt 506. The belt 506, driven by the belt roller 505, rotates to transport the finished product.
