Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, and in particular to an automatic fabric patch applicator and an automatic fabric patch applicator method. Background Technology

[0002] In textile manufacturing, it is often necessary to attach specific fabric pieces to flat materials such as cardboard and plastic sheets to create sample fabrics and other products. The types of fabric materials involved are numerous, and the thicknesses vary considerably. When attaching fabric pieces, it is crucial that they be aligned correctly, adhere firmly to the material, and that issues such as curling edges be avoided. However, due to the varying fabric thicknesses, existing automated equipment cannot reliably perform the actions of applying adhesive, picking up fabric, and attaching fabric. Currently, manual operation is predominantly used, which suffers from high efficiency and low cost. Summary of the Invention

[0003] Based on this, this application provides an automatic fabric patch applicator that realizes the feeding, adhesive application, and fabric application of the product to be patched, and automates the entire process.

[0004] An automatic patch applicator includes:

[0005] Conveying components, including conveyor elements for conveying materials;

[0006] The feeding assembly includes a feeding mechanism for acquiring materials and conveying them onto a conveyor in the conveying assembly;

[0007] The adhesive application assembly, located above the conveying assembly, is used to apply adhesive to the materials on the conveying components.

[0008] And the pressing assembly, located downstream of the adhesive applicator, is used to press the adhesive-applied material onto the fabric.

[0009] In some embodiments, the conveying assembly further includes a first limiting component disposed at the edge of the conveyor and extending along the conveying direction.

[0010] In some embodiments, the conveying assembly further includes a second limiting assembly disposed on one side of the transmission member for controlling the movement state of the transmission member. The second limiting assembly includes a limiting unit equipped with a sensor and a driving part for driving the limiting unit to move perpendicular to the direction of the conveying member. The limiting unit is used to detect whether the material has moved into place and control the movement state of the transmission member.

[0011] In some embodiments, the feeding mechanism includes a material picker for placing material onto the conveying assembly and a drive unit for driving the material picker to move.

[0012] In some embodiments, the adhesive application assembly includes an adhesive application mechanism, a first drive mechanism for driving the adhesive application mechanism to move along a first direction, and a second drive mechanism for driving the adhesive application mechanism to move along a second direction. The adhesive application mechanism is used to apply adhesive to the material on the conveyor and cut off the adhesive. The first direction is parallel to the conveying direction of the conveyor, and the second direction is perpendicular to the conveying direction.

[0013] In some embodiments, the pressing assembly includes a fabric cassette for loading fabric sheets and a fabric extrusion mechanism for pressing the fabric sheets out of the fabric cassette.

[0014] In some embodiments, the fabric box is provided with one or more feeding slots, the bottom of the feeding slots has an opening in the middle, and the bottom edge extends into the opening to support the fabric.

[0015] In some embodiments, the fabric pressing mechanism includes a pressing block for pressing the fabric out of the feeding trough and a drive unit for driving the pressing block to move.

[0016] In some implementations, the number of pressure blocks is the same as the number of feed slots in the fabric box.

[0017] In some embodiments, the automatic patch applicator also includes a receiving bin located downstream of the conveying assembly for collecting the finished patch material.

[0018] In some embodiments, the automatic patch applicator also includes a page-turning mechanism located downstream of the pressing group for turning over the material of the completed patch.

[0019] The automatic fabric applicator of this application completes the material acquisition and feeding process by controlling the conveying component, realizes the adhesive application and de-adhesion process by controlling the feeding component and the adhesive application component, and realizes the fabric applicator process by controlling the feeding component and the pressing component. All actions are completed by the device itself, realizing full automation of the process. In addition, the pressing component of this application directly presses the fabric onto the material through the pressing mechanism to achieve fabric application. While ensuring a firm bond between the fabric and the material, it can also effectively prevent the fabric from curling.

[0020] This application also provides an automatic fabric patch application method, comprising the following steps:

[0021] The feeding assembly controls the material to be transported onto the conveyor in the conveying assembly;

[0022] The control conveyor delivers the material to the area below the adhesive application assembly, and controls the adhesive application assembly to apply and then cut off the adhesive.

[0023] The control conveyor delivers the material to the bottom of the pressing assembly, and the control pressing assembly presses the fabric sheet onto the material that has been glued by the adhesive bonding assembly.

[0024] In some implementations, the drive unit in the control feeding mechanism drives the material picking component to transfer the material from the feeding box to the conveyor component;

[0025] The control conveyor transports the material to the area below the adhesive application assembly. The control adhesive application assembly applies double-sided tape to the material and then tears the tape through clamping and rotating actions.

[0026] The control conveyor belt transports the material to the bottom of the pressing assembly, and the control pressing assembly presses the fabric sheet from the fabric sheet box onto the material through the fabric sheet pressing mechanism. Attached Figure Description

[0045] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0046] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0047] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0048] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0049] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0050] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0051] The direction parallel to the conveying direction is defined as front and back, the direction perpendicular to the conveying plane is defined as up and down, and the direction orthogonal to front and back and up and down is defined as left and right.

[0052] See Figure 1-3 ,in, Figure 1 and Figure 2 A three-dimensional structural schematic diagram of an automatic patch applicator according to an embodiment of the present invention is shown. Figure 3 This is a front view of an automatic fabric patch applicator according to an embodiment of the present invention. The automatic fabric patch applicator includes a conveying component 1, a feeding component 2, an adhesive applicator 3, a fabric pressing component 4, and a control mechanism. The aforementioned control mechanism is electrically connected to the drive unit or control unit in each component to realize automated control functions. The control mechanism can be a programmable logic controller such as a PLC or PID controller.

[0053] The feeding assembly 2 is located upstream of the conveying assembly 1 and includes a feeding mechanism 21 for transporting materials to the conveyor 11. The feeding mechanism 21 includes a material-picking component 211 and a drive unit 212 that drives the material-picking component 211 to move in both vertical and horizontal directions. After the material-picking component 211 acquires the material, the drive unit 212 drives the material-picking component 211 to move upwards, and the material moves upwards accordingly. Subsequently, the drive unit 212 drives the material-picking component 211 to move horizontally, and the material moves towards the conveyor 11. After the movement is completed, the material falls and rests on the conveyor 11, and the drive unit 212 drives the material-picking component 211 back to its original position.

[0054] In some embodiments, the drive unit 212 may be a cylinder or an electric motor, preferably a cylinder.

[0055] In some embodiments, the material handling component 211 can be a robotic arm, or it can be... Figure 1 The vacuum suction cup shown can be connected to an external drive unit to continuously provide negative pressure to the vacuum suction cup. After the vacuum suction cup picks up the material through negative pressure, the drive unit 212 provides power to transfer the material to the top of the conveyor 11. Then the external drive unit of the vacuum suction cup stops providing negative pressure, so that the material leaves the vacuum suction cup and falls onto the conveyor 11.

[0056] In some embodiments, the feeding assembly further includes a feeding box 22 and a pusher plate 23 located on both sides of the drive unit 21. The feeding box 22 stores the material to be used, and the pusher plate 23 is located on the side of the conveyor 11 away from the feeding box 2, used to push back the excess part of the material when it exceeds the boundary of the conveyor 11. The pusher plate 23 includes a moving plate and a drive unit that drives the moving plate to move left and right. The pusher plate 23 is distributed along the side of the conveyor 11. In the conveying direction, the axis of the drive unit 212 is located between the two ends of the moving plate, ensuring that the material falls into the control area of ​​the pusher plate 23 when it falls. Under the action of the pusher plate, the boundary of the material is just aligned with the boundary 11 of the conveyor before it moves on the conveyor 11, indirectly keeping the positional relationship between the subsequent adhesive application and the fabric sheet and the material fixed.

[0057] In some embodiments, the drive unit may be a drive element such as a motor or a cylinder, preferably a cylinder, which can continuously drive the moving plate to reciprocate.

[0058] In some embodiments, the drive unit 212 spans over the conveyor 11 and extends to the upper feed box 2, so that the material picking member 211 can be suspended above the feed box 22, making it easier for the material picking member 211 to pick up materials from the feed box 22.

[0059] In some embodiments, the end of the drive unit 212 near the push plate 23 can be aligned with the conveyor in the vertical direction, further ensuring that the material is aligned with the side of the conveyor when it falls onto the conveyor.

[0060] In some embodiments, the movable plate in the push plate 23 can move back and forth continuously under the action of the drive unit, or it can be driven by a signal emitted by a sensor mounted on the movable plate facing the conveyor 11. When the sensor detects that the material is falling or staying on the conveyor, it emits a signal, and the control mechanism controls the drive unit to drive the movable plate to move.

[0061] The conveying assembly 1 includes a conveyor 11 that runs laterally through the entire automatic applicator, a drive unit that drives the conveyor to move, a first limiting assembly that limits the material on the conveyor, and a second limiting assembly that controls the movement of the conveyor belt.

[0062] The first limiting component 12 is located on one side of the conveyor 11 and is distributed along the side of the conveyor 11. Part of the first limiting component 12 is higher than the conveyor 11 to ensure that the material remains in the conveyor 11 during the conveying process and does not escape.

[0063] The second limiting component 13 is located on the side of the conveyor 11 away from the first limiting component, below the adhesive application component 3. The second limiting component 13 includes a mounting plate 132 with a sensor mounted on it. The mounting plate 132 is distributed along the side of the conveyor 11, with the sensor facing the conveyor 11. When the material has not reached the second limiting component 13 below the adhesive application component 3, i.e., when the sensor in the mounting plate 132 has not received a signal, the conveyor continues to move. When the material reaches the position of the second limiting component 13 under the transport of the conveyor 11, the transmitter on the mounting plate 132 captures the signal and transmits it to the control mechanism. The control mechanism controls the drive unit that drives the conveyor to stop driving, the conveyor 11 stops moving, and the control mechanism simultaneously controls the adhesive application component 11 to start working. After a certain delay, the conveyor continues to transport the material.

[0064] In some embodiments, the second limiting component 13 further includes a driving part 131 for driving the mounting plate 132 to move. The driving part 131 is located below the mounting plate 132 and is fixedly connected to the mounting plate 132. When the material is large or the material is in the flipped-open state, before the material reaches the second limiting component 13 below the adhesive application component 3, that is, when the sensor in the mounting plate 132 does not receive a signal, the second limiting component 13 is in a high position. That is, under the action of the driving part 131, the mounting plate 132 is partially located above the conveyor 11, blocking the material's forward direction. When the material reaches the position of the second limiting component 13 under the transport of the conveyor 11, the conveyor on the mounting plate 132 captures the signal and transmits the signal to the control mechanism. The control mechanism controls the drive unit that drives the conveyor to stop driving, and the transmission component 11 stops moving. At the same time, the control mechanism controls the adhesive application component 11 to start working. At the same time, the control mechanism also controls the drive unit of the second limiting component 13 to descend, causing the mounting plate 132 to move down until the second limiting component 13 is located below the conveyor 11, making way for the material to move forward. After a certain delay, the belt continues to transport the material.

[0065] In some implementations, the drive unit may be a drive element such as a motor or a cylinder.

[0066] In some embodiments, the conveyor 11 may be a conveyor belt, chain, etc., preferably a conveyor belt.

[0067] In some embodiments, the first limiting component 12 is located on the same side of the conveyor and the push plate 23.

[0068] In some embodiments, the first limiting component 12 may be distributed on the side of the adhesive application component 3, on the side of the fabric pressing component 4, or simultaneously on the sides of both the adhesive application component 3 and the fabric pressing component 4. It may also extend from the end of the push plate 23 near the adhesive application component 3 to the end of the conveyor near the fabric pressing component 4.

[0069] In some embodiments, the number of second limiting components 13 is one or more. Specifically, the number of second limiting components 13 includes, but is not limited to, one, two, three, four or more, preferably consistent with the number of adhesive application components arranged in the transmission direction of the drive component.

[0070] The adhesive application assembly 3 is located above the middle section of the conveyor 11, such as... Figure 4-7 As shown, the adhesive application assembly 3 includes an adhesive application mechanism 33, a second drive mechanism 32 that drives the adhesive application mechanism to move along a second direction, and a first drive mechanism 31 that drives the adhesive application mechanism 33 to move along a first direction.

[0071] See Figure 5 As shown, the first drive mechanism 31 includes a moving module 311 located in the middle and two front and rear slide rails 312 located on both sides; wherein the front and rear moving module 311 provides a power source for the back and forth movement of the adhesive applicator 33, driving the adhesive applicator 33 and the second drive mechanism as a whole to move back and forth along the longitudinal direction of the front and rear slide rails 312.

[0072] In some embodiments, the first drive mechanism 31 further includes a mounting block 313 and a connecting plate 314 connected to the second drive mechanism 32, with the mounting block 313 and the connecting plate 314 fixedly connected. The side of the mounting block 313 facing the front and rear slide rails 312 is fixedly connected to the moving module 311 and is equipped with a track that cooperates with the front and rear slide rails 312.

[0073] See Figure 4 As shown, the second drive mechanism 32 includes a moving module 321 located in the middle and two upper and lower sliding rails 322 located on both sides; wherein the moving module 321 provides a power source for the up-and-down movement of the adhesive applicator 33, driving the adhesive applicator 33 to move up and down along the longitudinal direction of the upper and lower sliding rails. The moving module 321 is fixedly connected to the first drive mechanism 31, so that when the first drive mechanism 31 moves back and forth, the second drive mechanism also moves back and forth accordingly.

[0074] In some embodiments, the moving module 321 in the second drive mechanism 32 is fixedly connected to the connecting plate 314 in the first drive mechanism 32, so that when the mounting block 313 moves back and forth longitudinally with the front and rear slide rails 312, the entire second drive mechanism 32 also moves accordingly.

[0075] In some embodiments, the second drive mechanism 32 further includes a mounting block 324 and a connecting plate 323 connected to the adhesive applicator 33, with the mounting block 324 and the connecting plate 323 fixedly connected. The mounting block 324 is distributed parallel to the mounting block 313 in the first drive mechanism 31, and both are parallel to the conveyor 11. The connecting plate 323 is fixedly connected to the upper and lower slide rails 322, so that when the upper and lower slide rails 322 move up and down, the mounting block 324 and the connecting plate 323 move up and down accordingly.

[0076] In some embodiments, there can be two connecting plates 314 and 323, so that the two connecting plates 314 are symmetrically fixedly connected to both sides of the moving module 321, and the connecting plates 323 are also symmetrically fixedly connected to both sides of the two upper and lower sliding rails, which makes the connection between components more stable and avoids the adhesive application mechanism from shifting during operation, thus affecting the adhesive application effect.

[0077] See Figure 7 and Figure 8 As shown, the adhesive applicator 33 includes a mounting plate 333 fixedly connected to the second drive mechanism 32, a mounting component 337 movably connected to the mounting plate 333 via a rotating shaft 331, a bearing 332 and a gear 336, and an intermediate plate 351 loaded with a double-sided adhesive conveying and recycling unit.

[0078] Specifically, the mounting plate 333 may be fixedly connected to the mounting block 324 in the second drive mechanism 32, so that when the first or second drive mechanism moves, the mounting plate 333 and the mounting component 337 and intermediate plate 351 that move based on the mounting plate 333 also move.

[0079] The mounting component 337 is movably connected to the mounting plate 333, and the mounting component 337 can rotate relative to the mounting plate 333 from below.

[0080] The bearing 332 is located above the mounting plate 333. The mounting plate 333 has a through hole at its center. The rotating shaft 331 passes through the bearing 332 and the through hole of the mounting plate 333 and is fixedly connected to the mounting component 337. This ensures that the mounting component 337 will not affect the mounting plate 333 when it rotates, and thus will not affect the second or first drive mechanism. In other words, the rotational movement during the adhesive application process will not cause unnecessary displacement of the entire adhesive application assembly.

[0081] In some embodiments, a gear 336 is provided between the mounting member 337 and the mounting plate 333, and the mounting member 337, which is fixedly connected to the gear, is rotated by a motor.

[0082] In some embodiments, a rack 335 is disposed next to the gear 336, and the rack 335 meshes with the gear 336. A drive unit 334 for driving the rack 335 is connected to the side of the rack 335 away from the gear 336. The drive unit 334 drives the rack 335 to perform linear motion. The meshing between the rack 335 and the gear 336 converts the linear motion of the rack 335 into the rotational motion of the gear 336. The fixed connection between the gear 336 and the mounting member 337 causes the mounting member 337 to rotate as the gear 336 rotates.

[0083] Double-sided tape includes cardboard, adhesive layer, and inner sleeve for fixing on the inside.

[0084] See Figure 6-8 As shown, the double-sided tape conveying and recycling unit includes a conveying area, an adhesive application area, and a recycling area. The double-sided tape first transports the cardboard covered with the adhesive layer through the conveying area to the adhesive application area. Then, in the adhesive application area, the adhesive layer separates from the cardboard and adheres to the material. The cardboard continues to the recycling area, where it is finally recycled.

[0085] The conveying area includes a bearing 339, a guide shaft 342, and a paper feed shaft 343, all located at the upper end of the intermediate plate 351. The bearing 339 holds double-sided adhesive tape 338, with the tape's inner sleeve 341 directly contacting the bearing 339. Both the guide shaft 342 and the paper feed shaft 343 are located on one side of the center of the bearing 339, ensuring that the surfaces of the double-sided adhesive tape in direct contact with both shafts are paper-holding surfaces, thus guiding and tightening the tape.

[0086] The adhesive application area is located on the opposite side of the center of the bearing 339 relative to the paper feed roller 343, and at the lower end of the intermediate plate 351. It includes a first transition roller 344, a paper output tube 345 fixedly connected to the intermediate plate 351, a first paper pressing lever 361 fixedly connected to the first transition roller 344, and a drive unit 362. The first paper pressing lever 361 and the drive unit 362 are both located on the opposite side of the intermediate plate 351, i.e., excluding the back of the paper output tube 345. The first transition roller 344 is fixedly connected to one end of the first paper pressing lever 361, and the other end of the first paper pressing lever 361 is fixedly connected to the drive unit 362.

[0087] The first paper-pressing lever 361 is movably connected to the intermediate plate 351 via a bearing. When the drive unit 362 is not working, the first transition roller 344 and the paper output tube 345 are adjacent to each other, allowing double-sided tape to pass through. When the drive unit 362 is working, it drives one end of the first paper-pressing lever 361 connected to it to move towards the paper shaft 343, causing the other end of the first paper-pressing lever 361 to drive the first transition roller 344 to move further closer towards the paper output tube 345 and clamp the double-sided tape.

[0088] The recycling area is located on the same side as the adhesive application area at the center of the bearing 339. It includes a second transition roller 346, a paper feed tube 347, a paper pressure tube 348, a paper recycling tube 349, a second paper pressure lever 364 fixedly connected to the paper pressure tube 348, and a drive unit 365 for driving the paper recycling tube 349. The second transition roller 346 is located between the paper output tube 345 and the paper feed tube 347, and serves to adjust the paper jam direction and improve the paper jam tension. The second transition roller 346 and the paper feed tube 347 are fixedly connected to the intermediate plate 351; the second paper pressing lever 364, which is fixedly connected to the paper pressing tube 348, is fixedly connected to the other side of the intermediate plate 351 through a bearing. A lever spring 363 is also connected between the second paper pressing lever 364 and the intermediate plate 351, so that the paper pressing tube 348 always stays close to the paper feed tube 347, which plays the role of tightening the paper jam; the drive unit 365 is fixedly connected to the other side of the intermediate plate 351, and drives the paper jam recovery tube 349 to rotate and recover the paper jam when working.

[0089] In some embodiments, the first paper pressing lever 361 is also connected to the intermediate plate 351 via a lever spring to prevent excessive clamping between the first transition roller 344 and the paper output tube 345 when the drive unit 362 drives the first paper pressing lever 361 to move, or even damage to the first transition roller 344 or the paper output tube 345 itself.

[0090] In some embodiments, a sensor 352 may be provided on the intermediate plate 351 between the paper pressure tube 348 and the paper jam recovery tube 349 to sense the tightness of the paper jam. When the lever spring 363 and the drive unit 365 are working normally, a certain pressure exists between the paper pressure tube 348 and the paper jam recovery tube 349 to clamp the paper jam and keep it in a taut state, so that a section of paper jam within the sensing range of the sensor can be kept in its position. However, if one or more of the components malfunction, the paper jam will loosen and cause a certain displacement. After the sensor 352 senses the loosening of the paper jam between the paper pressure tube 348 and the paper jam recovery tube 349, it will send a signal to the drive unit 365, causing the drive unit to work or accelerate its work to recover the paper jam to the paper jam recovery tube 349.

[0091] In some embodiments, the drive unit 365 may be a drive mechanism such as a motor or a cylinder, preferably a motor.

[0092] In some implementations, baffles 350 are also provided at both ends of the paper output tube to control the position of the double-sided adhesive tape, so as to prevent unnecessary displacement during movement and thus affect the adhesive application effect.

[0093] In some implementations, see Figure 6As shown, the placement of the first transition roller, the paper output tube, and the second transition roller is set such that the included angle formed by the connecting lines of the three axes is less than 90 degrees. In other words, the double-sided tape covers at least three-quarters of the shaft surface of the paper output tube, providing sufficient space for the adhesive layer to contact the material without affecting the effect of tearing the adhesive.

[0094] In some implementations, an automatic patch applicator may include more than one adhesive applicator component.

[0095] In some implementations, an adhesive application assembly may include more than one adhesive application mechanism, preferably two.

[0096] The fabric pressing assembly 4 is located downstream of the adhesive bonding assembly, such as... Figure 9-11 As shown, the device includes a fabric sheet box 41 for storing fabric sheets and a fabric sheet ejection mechanism 42 located above the fabric sheet box 41 to eject the fabric sheets from the box. The fabric sheet box 41 holds against the material covered with an adhesive layer, and has an upper and lower feeding groove for placing the fabric sheets; see also Figure 11 As shown, an opening 441 is provided in the middle of the bottom of the feeding trough, and the bottom edge extends into the opening 441 to form a support part 442 for supporting the fabric sheet.

[0097] See Figure 10 As shown, the fabric pressing mechanism 42 includes a drive unit 421 and a pressing block 423. The drive unit 421 is fixedly connected to the pressing block 423. When there are many pressing blocks 423, a mounting plate 422 can be provided between the drive unit 421 and the pressing block 423. The lower end of the drive unit 421 and the upper end of the pressing block 423 are both fixedly connected to the mounting plate 422, so that one drive unit 421 can drive multiple pressing blocks 423 at the same time.

[0098] The pressure block 423 includes a support plate 431 fixedly connected to the drive unit 421 or the mounting plate 422, a movable block 434 whose lower end is in direct contact with the fabric, a top post 435 connecting the support plate 431 and the movable block 434, and a spring top block 432 and a spring 433 located between the three. When the movable block 434 is pressed down, the spring 433 provides elastic force to press the fabric, so that when one drive unit 421 drives different pressure blocks 423, even if the fabric material or thickness of each pressure block 423 is different, a reliable pressing effect can still be guaranteed.

[0099] When the drive unit 421 drives the pressure block 423 to move downward, the movable block 434 in the pressure block 423 moves downward and enters the slot of the corresponding feeding trough, abutting against the fabric and reliably bonding the fabric or fabric pile at the bottom of each slot to the material through the adhesive layer. At the same time, the spring 433 provides elastic force to the movable block 434 to further press the fabric against the material. When the drive unit 421 moves upward and drives the pressure block 423 to move upward, the fabric box 41 retracts and separates from the material. The fabric or fabric pile at the bottom of each feeding trough is carried out from the bottom opening 441 of the feeding trough by the material covered with the adhesive layer, completing the single-layer fabric removal action and pressing out the bottom opening 441 of the fabric box 41.

[0100] In some implementations, the feeding trough can be formed by a plate separating the fabric box into spaces.

[0101] In some implementations, the cross-section of the pressing block is the same size and shape as the cross-section of the slot. The number of pressing blocks can also be the same as the number of slots to ensure efficient pressing of the fabric.

[0102] In some implementations, the shape, size, and number of feed troughs can be varied according to the shape, size, and requirements of the fabric. The shape and size of the opening 441 are also determined according to the shape and size of the fabric, and can be slightly smaller than the fabric.

[0103] In some embodiments, the number of top posts 435 can be 1, 2, 3, 4 or more, preferably an even number, more preferably 2.

[0104] In some embodiments, the automatic patch applicator also includes a receiving component 5 located on the outer side of the downstream end of the conveyor 11 for collecting the material of the completed patch.

[0105] In some embodiments, the receiving assembly 5 includes a receiving box 51 with an opening at the top. When the material of the finished patch slides out from the conveyor 11, it falls into the receiving box 51 by inertia, thus completing the collection of the material.

[0106] In some embodiments, the receiving assembly 5 further includes a receiving ramp 52 located on the extension line of the conveyor 11, a drive unit 53 for driving the receiving ramp 52 to move left and right, and two parallel slide rails 54 located at both ends of the receiving ramp 52 in the conveying direction of the transfer component. The receiving ramp 52 is located above the receiving box and gradually descends from one end near the conveyor 11 to the other end away from the conveyor 11, forming a ramp. The two slide rails 54 are perpendicular to the conveying direction of the transfer component. After the material completes the application of the fabric patch, it slides down onto the receiving ramp 52 due to the inertia of the transmission component 11. After collecting a portion of the material, the drive unit 53 drives the receiving ramp 52 to move rapidly away from the transmission component, so that the fabric patch material falls vertically into the receiving box 51 under the action of inertia, thus completing the collection of the material. Compared to the material sliding directly from the conveyor 11 into the receiving box 51, the material is supported by the receiving ramp 52 and then the receiving ramp 52 is pulled away so that the material falls into the receiving box 51. This ensures that the material falls into the receiving box more stably and the material collected in the receiving box 51 is stacked more neatly.

[0107] In some implementations, such as Figure 3 As shown, the automatic fabric applicator also includes a page-turning mechanism 66, located on the same side of the second limiting component downstream of the fabric pressing assembly 4, comprising a push plate 61 and a drive unit 62 for driving the push plate. Some materials require the fabric applicator to be in the open state. Before receiving the material, a sensor detects whether page turning is needed. If so, the drive unit 62 drives the push plate 61 to lift and turn the open page back.

[0108] This application also provides an automatic patch application method.

[0109] An automated fabric patch application method includes the following steps: First, a control mechanism controls a feeding assembly to transport material to a conveyor within a conveying assembly; then, the conveyor is controlled to transport the material below an adhesive applicator, where the adhesive applicator applies and cuts off the adhesive; finally, the conveyor is controlled to transport the material below a pressing assembly, where the pressing assembly presses the fabric patch onto the adhesive-applied material. The entire process is completed by the automated fabric patch application device, requiring no manual intervention, resulting in high efficiency and low cost.

[0110] In some embodiments, the control mechanism controls the drive unit in the feeding mechanism to drive the material picker to transfer the material from the feeding box to the conveyor; then the conveyor transports the material to the bottom of the adhesive application assembly, the adhesive application assembly applies double-sided tape to the material and then tears the tape through clamping and rotating actions; then the transmission belt transports the material to the bottom of the pressing assembly, the pressing assembly presses the fabric sheet from the fabric sheet box onto the material through the fabric sheet pressing mechanism.

[0111] In some implementations, after the pressing assembly presses the fabric sheet onto the material, the material can continue to move and fall into the receiving box on the outer side of the downstream end of the conveying assembly by means of inertia.

[0112] In some implementations, the feeding assembly drives the material-picking component to obtain the material via a drive unit, and then drives the material-picking component to move, so that the material also moves onto the conveyor.

[0113] In some implementations, the feeding assembly also includes a pusher plate that pushes back any excess material when it exceeds the boundary of the conveyor.

[0114] In some embodiments, when the adhesive applicator is working, the first drive mechanism drives the second drive mechanism and the adhesive applicator to move back and forth to a suitable position. The second drive mechanism moves downward so that the lower end of the adhesive applicator abuts against the material to be applicated. Driven by the first drive mechanism, the adhesive applicator peels off the adhesive paper adhered to the double-sided tape and completes the action of fixing the double-sided tape to the material. During the applicator process, the double-sided tape starts from the inner sleeve of the double-sided tape on the bearing, passes through the guide shaft, the paper feed shaft and the first transition roller, and then separates from the cardboard at the paper output tube. The adhesive layer remains on the material, and the cardboard passes around the second transition roller, the paper feed tube and the paper pressure tube and is then collected by the cardboard recovery tube. The collection action of the cardboard recovery tube is driven by the drive unit fixedly connected to the cardboard recovery tube.

[0115] When the adhesive application assembly finishes its operation, one end of the first paper-pressing lever moves downward under the drive of the drive unit, causing the first transition roller at the other end of the first paper-pressing lever to be lifted and tightly fitted against the paper output tube, thus clamping the double-sided adhesive. At the same time, the rack and pinion power source drives the rack to move, which in turn rotates the gear, causing the mounting component to rotate and the tape to be torn off. The second drive mechanism then moves the adhesive application assembly upward, away from the material.

[0116] In some embodiments, when the conveyor transports the material to the underside of the fabric pressing assembly, the drive unit moves downward to press the fabric sheet out of the fabric sheet box and tightly adhere it to the adhesive on the material, thus completing the fabric sheet application action.

[0117] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0118] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
