Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, specifically to an edge banding conveyor mechanism. Background Technology

[0002] In the edge banding process of custom furniture panels, the conveying link of the edge banding tape feeding device not only needs to complete the forward feeding of the edge banding tape to the edge banding machine, but also needs to recycle the remaining edge banding tape in the guide channel and on the material roll after changing the edge banding tape specifications, stopping for maintenance, or after a single edge banding operation. The rationality of the transportation logic in the recycling link directly affects the raw material utilization rate, material changing efficiency, and subsequent feeding accuracy. Currently, existing edge banding conveyor devices have significant flaws in their transport logic design for the recycling angle, making them unsuitable for the high-efficiency, continuous processing requirements of multi-specification switching in customized furniture production. On the one hand, the recycling of edge banding in traditional conveyor devices relies heavily on manual pulling, requiring operators to manually drag the remaining edge banding in the guide channel back to the roll. This not only results in low recycling efficiency but also easily leads to wrinkles and stretching deformation of the edge banding due to uneven manual pulling force. When the deformed edge banding is fed again, it is prone to jamming and guide path deviation, which in turn causes defects in edge banding quality. At the same time, manual recycling cannot accurately control the recycling length, which can easily lead to over-recycling, causing the roll to become loose, or under-recycling, causing the remaining edge banding to be exposed outside the device and contaminated with dust, affecting subsequent use.

[0003] On the other hand, some conveyor systems equipped with mechanical recycling structures have recycling logic that is independent of the forward feeding logic and lacks coordination. These systems often use an additional independent motor to drive a friction wheel to reverse the tray containing the edge banding for recycling. The recycling endpoint can only be determined by manual observation, which means that the edge banding tip cannot be accurately reset to the waiting position after recycling. When feeding material again, the forward feeding mechanism needs to be restarted to calibrate the tip position, which not only increases the number of operation steps but also prolongs the downtime for material changes. This defect is particularly noticeable in scenarios where multiple specifications of edge banding are frequently switched in customized furniture manufacturing, where the loss of production efficiency is more significant.

[0004] Therefore, there is an urgent need to develop a sealing tape conveying mechanism. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an edge banding tape conveying mechanism for use with a pallet containing edge banding tape in a feeding device, enabling precise recovery of remaining edge banding tape during tape replacement or machine shutdown. The implementation of this technical solution is as follows: An edge banding tape conveying mechanism, comprising: The forward drive assembly includes a drive roller, a first motor, and a first cylinder; the drive roller is disposed on both sides of the edge sealing strip, and drives the edge sealing strip to move through the two drive rollers; the drive roller is disposed on the output shaft of the first motor; the first cylinder is used to drive the first motor and the drive roller to move closer to or away from the edge sealing strip. An encoder, wherein the encoder is disposed on one side of one of the first motors, and the encoder disk abuts against the sealing tape; The second cylinder is used to move the encoder closer to or away from the sealing tape; A photoelectric sensor is installed at the outlet of the feeding device. The photoelectric sensor works in conjunction with an encoder to measure the length of the sealing tape being sent out or retrieved. The recycling drive assembly includes a friction wheel, a second motor, and a third cylinder; the friction wheel is disposed on one side of the tray equipped with edge sealing tape, the output shaft of the second motor is fixedly connected to the friction wheel, and the third cylinder is used to drive the friction wheel and the second motor to move closer to or away from the tray equipped with edge sealing tape.

[0006] Preferably, it also includes a brake, which is disposed between the friction wheel and the second motor, and the brake is used to brake the friction wheel to stop the tray.

[0007] Preferably, the brake is an electromagnetic brake.

[0008] Preferably, the piston rod of the first cylinder is connected to a first mounting plate, and the housing of the first motor is fixed to the first mounting plate; the piston rod of the second cylinder is connected to a second mounting plate, and the housing of the encoder is fixed to the second mounting plate; the piston rod of the third cylinder is connected to a third mounting plate, and the housing of the second motor is fixed to the third mounting plate.

[0009] Preferably, the first cylinder, the second cylinder, and the third cylinder are cylinders with guide rods.

[0010] Preferably, the friction wheel is a rubber friction wheel. Compared with the prior art, this application has the following advantages: The forward drive component of the conveying mechanism in this technical solution uses a first cylinder with a guide rod to drive the active roller to stably clamp the edge banding tape. This, combined with the synchronous drive of the active rollers on both sides, prevents the edge banding tape from slipping or shifting during conveying. At the same time, a second cylinder drives the encoder disk to accurately contact the edge banding tape. The photoelectric sensor at the outlet of the feeding device calculates the length of the edge banding tape in real time, which can control the positioning error of the edge banding tape feeding to a very small range. This completely solves the problem of inaccurate edge banding tape waiting position and the need for repeated manual calibration in traditional feeding methods, and greatly improves the accuracy and automation of edge banding tape feeding.

[0011] In this technical solution, during the edge banding tape recycling process, the recycling drive component uses a third cylinder to drive a rubber friction wheel to smoothly contact the pallet. The rubber material prevents hard damage to the pallet. During recycling, a second motor drives the friction wheel to reverse the pallet. Combined with the secondary signal triggering from the photoelectric sensor, the recycling of the edge banding tape into the feeding device can be precisely controlled, avoiding over-recycling that leads to loose material rolls or under-recycling that results in residual contamination. The recycling accuracy and efficiency are significantly better than manual recycling. Whether changing edge banding tape specifications, stopping for maintenance, or completing a single operation, the recycling action can be completed automatically, adapting to multiple material change needs, further reducing the labor intensity of operators, and improving the automation level of the edge banding tape feeding device.

[0017] Embodiments of this application provide an edge banding tape conveying mechanism, which is installed within an edge banding tape feeding device 300 and is used in conjunction with the feeding device 300 and a tray 200 containing edge banding tape 100 within the feeding device; such as Figure 1-7As shown, the conveying mechanism includes a forward drive assembly 1, an encoder 2, a second cylinder 3, a photoelectric sensor 4, and a recovery drive assembly 5. The forward drive assembly 1 includes a drive roller 11, a first motor 12, and a first cylinder 13. The drive rollers 11 are arranged on both sides of the sealing strip 100, and the sealing strip 100 is moved by the drive rollers 11 on both sides. The drive rollers 11 are arranged on the output shaft of the first motor 12. The first cylinder 13 is used to drive the first motor 12 and the drive rollers 11 to move closer to or away from the sealing strip 100. The encoder 2 is arranged on one side of one of the first motors 12, and the code disk 21 of the encoder 2 is connected to the sealing strip 100. 0-phase contact; the second cylinder 3 is used to drive the encoder 2 to approach or move away from the sealing tape 100; the photoelectric sensor 4 is set at the outlet of the feeding device 300, and the photoelectric sensor 4 cooperates with the encoder 2 to measure the length of the sealing tape 100 being sent out or retrieved; the retrieval drive assembly 5 includes a friction wheel 51, a second motor 52 and a third cylinder 53; the friction wheel 51 is set on one side of the tray 200 containing the sealing tape 100, the output shaft of the second motor 52 is fixedly connected to the friction wheel 51, and the third cylinder 53 is used to drive the friction wheel 51 and the second motor 52 to approach or move away from the tray 200 containing the sealing tape 100.

[0018] It should be noted that the encoder is a photoelectric encoder, a type of measuring device. A photoelectric encoder converts physical displacement in motion into a digital signal output to achieve precise position detection and control. This includes the measurement of parameters such as rotational speed, angle, and linear displacement, and it is widely used in various mechanical and automation systems.

[0019] Specifically, such as Figure 2-6As shown, when loading and unloading pallet 200, the drive rollers 11 and the code disk 21 of the encoder 2 on both sides of the sealing strip 100 do not abut against the sealing strip 100, so that the sealing strip 100 can enter between the drive rollers 11. The friction wheel 51 does not abut against the pallet 200, leaving a certain position for the replacement of pallet 200. When the edge sealing tape 100 is aligned with the outlet of the feeding device 300 and ready to be discharged, the first cylinder 13 drives the first motor 12 and the active roller 11 to move toward the edge sealing tape 100, so that the active roller 11 can abut and clamp the edge sealing tape 100. At the same time, the code disk 21 of the encoder 2 abuts the edge sealing tape 100. After the active roller 11 clamps the edge sealing tape 100, the first motor 12 is started, driving the active roller 11 to rotate and drive the edge sealing tape 100 to output the material to the outlet. When the edge sealing tape 100 moves to below the photoelectric sensor 4, the photoelectric sensor 4 triggers a signal, and the encoder 2 calculates the length of the edge sealing tape 100. When the preset feeding length is reached, the first motor 12 stops rotating, completing the precise positioning of the edge sealing tape 100. By using photoelectric sensor 4 and encoder 2 to calculate the length of edge banding tape 100 in real time, the feeding and positioning error of edge banding tape 100 can be controlled to a very small range, completely solving the problem of inaccurate waiting position of edge banding tape 100 and the need for repeated manual calibration in traditional feeding, and greatly improving the accuracy and automation of edge banding tape 100 feeding.

[0020] In some implementations, such as Figure 4 and Figure 7 As shown, the pushing device also includes a brake 6, which is disposed between the friction wheel 51 and the second motor 52. The brake 6 is used to stop the tray 200. Preferably, the brake 6 is an electromagnetic brake, which is existing technology. Since the edge sealing tape 100 drives the tray 200 to rotate when it is feeding material, the friction wheel 51 is always in contact with the tray 200 when conveying and retrieving the edge sealing tape 100, and rotates with the tray 200. During this period, the second motor 52 does not work. When it is necessary to stop feeding material, the brake 6 is energized to brake the friction wheel 51, so that the friction wheel 51 stops rotating. Since the friction wheel 51 is in contact with the tray 200, the tray also stops rotating, so that the edge sealing tape 100 installed on the tray 200 stops feeding material.

[0021] It should be noted that the fact that the edge banding tape 100 drives the tray 200 to rotate during the output feeding is not the invention point of this device. The specific way in which the edge banding tape drives the tray to rotate will not be described in detail.

[0022] In some implementations, such as Figure 4 and Figure 5As shown, the piston rod of the first cylinder 13 is connected to the first mounting plate 131, and the housing of the first motor 12 is fixed on the first mounting plate 131. The first cylinder 13 drives the first mounting plate 131 to move the first motor 12 and the drive roller 11. The piston rod of the second cylinder 3 is connected to the second mounting plate 31, and the housing of the encoder 2 is fixed on the second mounting plate 31. The second cylinder 3 drives the second mounting plate 31 to move the encoder 2. The piston rod of the third cylinder 53 is connected to the third mounting plate 531, and the housing of the second motor 52 is fixed on the third mounting plate 531. The third cylinder 53 drives the third mounting plate 531 to move the second motor 52 and the friction wheel 51.

[0023] Preferably, the first cylinder 13, the second cylinder 3, and the third cylinder 53 are cylinders with guide rods; the guide rods are arranged on both sides of the cylinder to support and guide the movement of the piston rod, preventing it from shifting due to lateral forces and preventing the shift from affecting the docking accuracy. It should be noted that the gas source supplied to the cylinders in this application is connected to an air pump. The air pump is an external device used to provide the gas source. The pressure of the gas source is selected according to requirements. The air pump is directly obtained from the prior art; therefore, its structure is not specifically described in this application.

[0024] In some implementations, such as Figure 4 and Figure 7 As shown, the friction wheel 51 is a rubber friction wheel. When the edge banding tape specification is changed, during machine shutdown for maintenance, or after a single edge banding operation, the remaining edge banding tape 100 needs to be recycled. At this time, the friction wheel 51 is first braked by the electromagnetic brake 6 to stop the tray 200, so that the edge banding tape 100 installed on the tray 200 stops feeding. Then the electromagnetic brake 6 is de-energized, and the second motor 52 is started. The output shaft of the second motor 52 drives the friction wheel 51 to rotate, which in turn drives the tray 200 to rotate and recycle the edge banding tape 100. The edge banding tape 100 returns to the inside of the feeding device 300. When the edge banding tape 100 has completely passed the photoelectric sensor 4, the photoelectric sensor 4 triggers a signal again, and the encoder 2 starts working. When it returns to the inside of the feeding device 300, the second motor 52 stops rotating, thus completing the recycling action of the edge banding tape 100. This achieves accurate recycling of the remaining edge banding tape 100 when the edge banding tape 100 is replaced or the machine is stopped.

[0025] The working principle of the edge banding conveyor mechanism in this embodiment is as follows: During operation: During the pallet assembly stage 200, the drive rollers 11 and encoder discs 21 on both sides of the edge banding 100 do not contact the edge banding 100, leaving space for the edge banding 100 to enter; the friction wheel 51 does not contact the pallet 200; when the edge banding 100 is aligned with the outlet of the feeding device 300, the first cylinder 13 drives the first mounting plate 131 to move the first motor 12 and drive rollers 11 toward the edge banding 100, causing the drive rollers 11 to contact and clamp the edge banding 100, while the second... Cylinder 3 drives the second mounting plate 31 to move the encoder 2 toward the sealing tape 100, causing the encoder 2 code disk 21 to abut against the sealing tape 100; the third cylinder 53 drives the third mounting plate 531 to move the friction wheel 51 to abut against the tray 200; after the two side drive rollers 11 clamp, the first motor 12 is started, driving the drive rollers 11 to drive the sealing tape 100 to the outlet for feeding. When the sealing tape 100 moves to below the photoelectric sensor 4 at the outlet, the photoelectric sensor 4 triggers a signal, and the encoder... 2. The length of the edge banding tape 100 is calculated accordingly. When the preset waiting length is reached, the first motor 12 stops, completing the precise waiting positioning. When the edge banding tape 100 is output and fed, it drives the tray 200 to rotate. When it is necessary to stop feeding, the electromagnetic brake 6 set between the friction wheel 51 and the second motor 52 brakes the friction wheel 51 to stop the tray 200. When the edge banding tape 100 specification is changed, the machine is stopped for maintenance, or the remaining edge banding tape 100 needs to be recycled after a single edge banding operation, the electromagnetic brake 6 first brakes the friction wheel 51 to stop the tray 200, so that the edge banding tape 100 stops feeding. Then, after the electromagnetic brake 6 is de-energized, the second motor 52 is started. The second motor 52 drives the friction wheel 51 to drive the tray 200 to rotate and recycle the edge banding tape 100. When the edge banding tape 100 has completely passed the photoelectric sensor 4, the photoelectric sensor 4 triggers the signal again, the encoder 2 operates, the edge banding tape 100 returns to the inside of the feeding device 300, the second motor 52 stops, and the edge banding tape 100 recycling action is completed.

[0026] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
