TECHNICAL FIELD

[0001] The present application relates to the technical field of automatic glove folding, in particular to a glove cross folding device and folding method. BACKGROUND

[0002] When folding the existing medical disposable gloves, the glove wrist is turned outwards to facilitate separation of the gloves during use, avoiding contamination of the outer surface of the gloves. However, this folding method requires multiple folding processes for the gloves, which is generally completed by manual folding in the prior art. On the one hand, this increases labor costs, and on the other hand, the size accuracy of manual folding is low, and sometimes the fingers are also folded into the wrist cavity, resulting in the need to pull out or shake out the fingers during use, increasing the time required for use and the possibility of contamination of the fingers.

[0018] like Figures 1 to 11As shown, a glove folding device includes a sleeve mechanism 1, a sleeve sliding mechanism 2, a gathering and clamping mechanism 3, and a clamping and sliding mechanism 4. There are two sleeve sliding mechanisms 2, each with multiple sleeve mechanisms 1. The sleeve mechanisms 1 on both sides of the sleeve sliding mechanisms 2 are arranged opposite each other, have the same number, and move synchronously. A clamping and sliding mechanism 4 is arranged between the two sides of the sleeve sliding mechanisms 2. Multiple gathering and clamping mechanisms 3 are arranged on the clamping and sliding mechanism 4. The gathering and clamping mechanisms 3 move synchronously with the sleeve mechanisms 1 on both sides. The glove folding action is achieved through the relative stationary state of each gathering and clamping mechanism 3 and the sleeve mechanisms 1 on both sides. A glove removal assembly 5 is located downstream of the moving direction of the gathering and clamping mechanism 3 and includes removal fingers 573 for gripping the glove from the gathering and clamping mechanism 3. Specifically, the sleeve guide rail 21 is oblong and arranged in the horizontal direction. The sleeve mechanism 1 moves cyclically on the sleeve guide rail 21. The outer side of the sleeve guide rail 21 is the glove fitting part, and the inner side is the glove folding part. The clamping sliding guide rail 41 is oblong and arranged in the vertical direction.

[0019] Specifically, the sleeve sliding mechanism 2 includes a sleeve guide rail 21, a sleeve sliding chain 22, and a sleeve slide 23. The sleeve sliding chain 22 moves cyclically along the sleeve guide rail 21, and the sleeve slide 23 is fixedly connected to each sleeve mechanism 1. The sleeve slide 23 is mounted on the sleeve sliding chain 22 and drives the sleeve mechanism 1 to move with the sleeve sliding chain 22. Preferably, the sleeve slide 23 is provided with sleeve sliding guide wheels 24. There are multiple sleeve sliding guide wheels 24, which are arranged in pairs. Each pair of sleeve sliding guide wheels 24 is engaged with both sides of the sleeve guide rail 21 and moves along the sleeve guide rail 21 to prevent the sleeve mechanism 1 from shifting or slipping. The clamping and sliding mechanism 4 includes a clamping and sliding guide rail 41, a clamping and sliding chain 42, and a clamping slide 43. The clamping and sliding chain 42 moves cyclically along the clamping and sliding guide rail 41. The clamping slide 43 is fixedly connected to each clamping and retracting mechanism 3. The clamping slide 43 is mounted on the clamping and sliding chain 42 and drives the retracting clamping mechanism 3 to move with the clamping and sliding chain 42. Preferably, the clamping slide 43 is provided with clamping and sliding guide wheels 44. There are multiple clamping and sliding guide wheels 44, which are arranged in pairs. Each pair of clamping and sliding guide wheels 44 is engaged with both sides of the clamping and sliding guide rail 41 and moves along the clamping and sliding guide rail 41 to prevent the retracting clamping mechanism 3 from shifting or slipping.

[0020] like Figures 5 to 7As shown, the sleeve mechanism 1 includes a sleeve mounting base 11, and an outer sleeve 14, an inner sleeve 15, and a fixing block 12 arranged coaxially from the outside to the inside. The fixing block 12 is fixedly connected to the sleeve mounting base 11 on the side near the gathering and clamping mechanism 3, and the fixing block 12 is provided with a vent hole 121 for inflating the inside of the glove. The outer sleeve 14 and the inner sleeve 15 slide axially relative to the sleeve mounting base 11. The gathering and clamping mechanism 3 includes a gathering bracket 326 and a hinged clamping plate 355. The gathering bracket 326 is a U-shaped structure with an upward opening, and the gathering bracket 326 moves vertically relative to the hinged clamping plate 355. Two rotatable combs 345 are hinged to the two opposite side walls of the 26. The hinged clamping plate 355 is set in the opening groove above the gathering bracket 326. The hinged clamping plate 355 is a U-shaped structure with the opening facing upward, and the U-shaped groove forms a glove placement space. There are two hinged clamping plates 355, which extend along the length of the gathering bracket 326. The two hinged clamping plates 355 are hinged to the hinge fixing block 363 at their closest ends. The hinge fixing block 363 is fixed relative to the sleeve mounting seat 11. The two hinged clamping plates 355 rotate relative to each other, and the rotation axis of the hinged clamping plate 355 is perpendicular to the rotation axis of the comb 345 in the horizontal plane. When both the outer sleeve 14 and the inner sleeve 15 move to the retracted position, the fixing block 12 is exposed outside the inner sleeve 15; when both the outer sleeve 14 and the inner sleeve 15 move to the extended position, the fixing block 12 and the end of the hinged clamping plate 355 near the sleeve mechanism 1 are contained in the hollow cavity of the outer sleeve 14 and the inner sleeve 15.

[0021] A spring piece 143 is provided on the inner wall of the outer sleeve 14. The spring piece 143 is made of elastic material. A spring piece clearance hole 142 is provided radially on the side wall of the outer sleeve 14. The spring piece clearance hole 142 is a through hole. The spring piece 143 includes a connecting part and an actuating part. The actuating part is fixedly connected to the side of the connecting part away from the sleeve mounting seat 11. The middle part of the actuating part is bent towards the central axis, and the end of the actuating part is bent towards the outer wall of the outer sleeve 14. When the actuating part is in the first position, the end of the actuating part passes through the spring piece clearance hole 142, and the outer edge of the end protrudes from the outer wall of the outer sleeve at the spring piece clearance hole 142. In the second position, the end of the actuating part does not protrude from the outer wall of the outer sleeve at the spring tab clearance hole 142; the spring tab pressure ring 151 is fixedly connected to the inner sleeve 15. When the inner wall of the end face of the outer sleeve 14 and the outer wall of the end face of the inner sleeve 15 reach a predetermined axial distance, the spring tab pressure ring 151 abuts against the actuating part and pushes the actuating part outward to the first position. Thus, by adjusting the relative position of the inner sleeve 15 and the outer sleeve 14, the extension and retraction of the spring tab 143 are controlled. When the actuating part of the spring tab 143 is in the first position, the outwardly protruding end of the actuating part can hook the closing ring at the end of the glove wrist, thus playing a positioning role.

[0022] Furthermore, a sleeve ring 141 is provided on the outside of the outer sleeve 14. The sleeve ring 141 is formed by a radial inward recess on the outer side wall of the outer sleeve 14, and the sleeve ring 141 is located on the side of the spring tab clearance hole 142 near the sleeve mounting base 11. By providing the sleeve ring 141, a positioning area is provided for the glove to be fitted on the sleeve mechanism 1, that is, the glove's closing ring can pass through the spring tab clearance hole 142 and be located at the sleeve ring 141, which provides an operating standard for the operator and also reduces the requirements for operating accuracy.

[0023] like Figure 6 and Figure 7 As shown, a sleeve limiting rod 161 is axially fixedly connected to the end face of the outer sleeve 14, and a sleeve limiting hole is provided axially on the end face of the inner sleeve 15. The sleeve limiting rod 161 passes through the sleeve limiting hole, and the inner sleeve 15 slides relative to the sleeve limiting rod 161. The end of the sleeve limiting rod 161 protrudes radially outward to form a limiting block, and the diameter of the limiting block is larger than the diameter of the sleeve limiting hole. A sleeve return spring 162 is sleeved on the sleeve limiting rod 161. The sleeve return spring 162 is a compression spring and abuts between the end face of the outer sleeve 14 and the end face of the inner sleeve 15. By setting the sleeve return spring 162, the outer sleeve 14 and the inner sleeve 15 maintain a predetermined axial distance in the default state, so that the moving part of the spring piece 143 is in the second position in the default state, thereby achieving stable positioning of the glove.

[0024] The sleeve mechanism also includes a sleeve cylinder 13 and a sleeve sliding plate 131. The sleeve cylinder 13 is fixedly mounted on the sleeve mounting base 11 and drives the sleeve sliding plate 131 to move relative to the sleeve mounting base 11. The outer sleeve 14 is fixedly mounted on the sleeve sliding plate 131, so that the movement of the sleeve cylinder 13 drives the sleeve sliding plate 131, the outer sleeve 14, and the inner sleeve 15 to move axially synchronously. Furthermore, by using other cylinders, motors, or other linear drive components, the axial movement of the outer sleeve 14 relative to the inner sleeve 15 can be further controlled.

[0025] like Figure 8 and Figure 9 As shown, the gathering and clamping mechanism 3 also includes a clamping and fixing plate 31, a first action component that drives the gathering bracket 326 and the comb 345 to move, and a second action component that drives the hinged clamping plate 355 to move.

[0026] The first actuating component includes a first lifting rod 322, a first lifting plate 323, a first limiting rod 324, and a hinge mechanism. The first lifting rod 322 passes through the clamping and fixing plate 31 and slides vertically relative to the clamping and fixing plate 31. The first lifting rod 322 can be driven by other mechanical actuating components such as cylinders or motors. The first lifting plate 323 is fixedly connected to the first lifting rod 322. The first limiting rod 324 passes through the first lifting plate 323 and the clamping and fixing plate 31. The upper end of the first limiting rod 324 is fixedly connected to a retracting bracket 326, and the lower end is fixedly connected to a first limiting stop. When the first limiting stop is not in contact with the clamping and fixing plate 31, the first limiting rod 324 and the first lifting plate 323 move synchronously. When the first limiting stop abuts against the bottom surface of the clamping and fixing plate 31, the first lifting plate 323 moves upward relative to the first limiting rod 324. Optionally, a spring can be abutted between the first lifting plate 323 and the retracting bracket 326, thereby enabling the first actuating component to achieve dual-stroke control: in the first stroke, the spring applies a force to the first lifting plate 323 away from the retracting bracket 326, causing the first lifting plate 323 and the first limiting rod 324 to rise synchronously; in the second stroke, the first limiting rod 324 and the retracting bracket 326 remain fixed, and the first lifting plate 323 moves towards the retracting bracket 326 against the spring force. The hinge mechanism includes a hinge bracket 341, a hinge rod 342, and a hinge pressure plate 343 that are hinged sequentially. The hinge bracket 341 is fixedly installed on the first lifting plate 323, and the hinge pressure plate 343 is fixedly installed on the retracting pressure plate 344. The retracting pressure plate 344 is hinged to the top of two opposite side walls of the retracting bracket 326, and the comb 345 is fixedly connected to the retracting pressure plate 344. The above structure enables dual-stroke control. Taking the upward process as an example: In the first stroke, the first lifting rod 322 drives the first lifting plate 323, the first limiting rod 324, the retracting bracket 326, and the comb 345 to rise synchronously until the first limiting baffle abuts against the clamping and fixing plate 31. During the upward process, the comb 345 remains open and does not rotate. In the second stroke, the first lifting rod 322 drives the first lifting plate 323 to rise. The first limiting rod 324 and the retracting bracket 326 remain fixed. During the upward process, the first lifting plate 323 drives the hinge mechanism to move and rotate, causing the hinge pressure plate 343 to drive the retracting pressure plate 344 and the comb 345 to retract inward.

[0027] The second actuating component includes a fixed column 361, a second lifting rod 352, a second lifting block 353, and a hinged clamping rod 354. The bottom of the fixed column 361 is fixedly connected to the clamping plate 31, and the top of the fixed column 361 is fixedly connected to the hinged block 363. The hinged clamping plate 355 is hinged to the hinged block 363. The second lifting rod 353 passes through the clamping plate 31 and slides vertically relative to the clamping plate 31. The second lifting block 353 is fixedly connected to the top of the second lifting rod 352 and is sleeved on the outside of the fixed column 361, sliding vertically relative to the fixed column 361. The lower end of the hinged clamping rod 354 is hinged to the second lifting block 353, and the upper end is hinged to the hinged clamping plate 355. There are two hinged clamping rods 354, and the two hinged clamping rods 354 move synchronously and relative to each other. When the second lifting rod 352 drives the second lifting block 353 to move upward, the two hinged clamping rods 354 move upward and rotate, causing the hinged clamping plate 355 to close inward.

[0028] Furthermore, the clamping and sliding mechanism 4 can also be equipped with a cam structure, with a first roller 321 connected below the first lifting rod 322 and a second roller 351 connected below the second lifting rod 352. The roller slides along the cam structure and achieves up-and-down undulations according to the shape of the cam surface, thereby controlling the specific actions and action rhythm of the closing clamping mechanism 3.

[0029] Furthermore, an inner clamping mounting shaft is fixedly connected above the hinge fixing block 363. The inner clamping mounting shaft is parallel to the rotation axis of the hinge clamping plate 355. An inner clamping torsion spring 371 is sleeved on the inner clamping mounting shaft. An inner clamping plate 372 is hinged on the hinge fixing block 363. The inner clamping plate 372 is positioned above the hinge clamping plate 355. The inner clamping plates 372 are arranged in pairs on opposite sides of the inner clamping mounting shaft, and the rotation axis of the inner clamping plate 372 is parallel to the rotation axis of the hinge clamping plate 355. The distance between the hinge points of the two inner clamping plates 372 is less than the distance between the hinge points of the two hinge clamping plates 355. The two ends of the inner clamping torsion spring 371 abut against the upper surface of the inner clamping plate 372. When the hinge clamping plate 355 closes inward relative to the inner clamping plate 372, it abuts against the inner clamping plate 372 and drives the inner clamping plate 372 to close inward relative to the inner clamping plate 372. This reduces the folding space of the inner clamping plate 372 at the folding position in the middle of the paired gloves, thereby reducing the thickness of the finished folded gloves.

[0030] A first fixed frame 332 is fixedly installed on the first lifting plate 323. A first guide post 331 is fixedly connected vertically below the retracting bracket 326. The first guide post 331 passes through the first fixed frame 332 and moves vertically relative to the first fixed frame 332. A first return spring 333 is sleeved on the first guide post 331. The first return spring 333 abuts between the retracting bracket 326 and the first fixed frame 332. A limiting protrusion is formed on the first limiting rod 324 in a radial outward direction to limit the lowest position of the first lifting plate 323 relative to the retracting bracket 326. A second return spring 362 is sleeved on the fixed post 361. The second return spring 362 abuts between the hinged fixed block 363 and the second lifting block 353. The first return spring 333 keeps the first lifting plate 323 in a low position relative to the retracting bracket 326 in the default state, thereby keeping the comb 345 in the unfolded state; the second return spring 362 keeps the second lifting block 353 in a low position relative to the hinge fixing block 363 in the default state, thereby keeping the hinge clamp 355 in the unfolded state.

[0031] like Figure 10 and Figure 11 As shown, the system also includes a glove removal assembly 5, which is located downstream of the retractable clamping mechanism 3 in its moving direction and includes removal fingers 573 for gripping the glove from the retractable clamping mechanism 3. Specifically, the glove removal assembly includes a removal fixing frame 51, an arc-shaped guide rail 52, and a removal mechanism. The arc-shaped guide rail 52 is mounted on the removal fixing frame 51, with its arc-shaped opening facing the clamping sliding mechanism 4. There are two arc-shaped guide rails 52, which are arranged in parallel. The removal mechanism is slidably mounted on the opposite inner side of the arc-shaped guide rail 52. The two removal mechanisms alternately move to the retractable clamping mechanism 3 to perform clamping, thereby improving clamping efficiency. Specifically, a hinge shaft 531 is rotatably connected to the clamping and removing frame 51. Two sets of hinge rods 532 are connected to the hinge shaft 531. The lower end of each set of hinge rods 532 is fixedly connected to the hinge shaft 531 and rotates synchronously with the hinge shaft 531. The upper end of the hinge rods 532 is fixedly connected to the clamping and removing mechanism, specifically the fixed connecting frame 541 of the clamping and removing mechanism. Thus, the rotation of the hinge shaft 531 drives the rotation and movement of the hinge rods 532, realizing the sliding of the clamping and removing mechanism on the arc-shaped guide rail 52. By staggering the connection angles between the two sets of hinge rods 532 and the hinge shaft 531, the alternating action of the two clamping and removing mechanisms can be achieved.

[0032] Since the target clamping position of the finger 573 is in the middle of the retracting bracket 326 in the retracting clamping mechanism, the accurate clamping area is small. Furthermore, the two clamping mechanisms move and clamp in parallel, resulting in an overlap in their vertical positions, which can cause interference during alternating vertical movement. Therefore, it is necessary to ensure that the clamping mechanisms avoid each other during vertical movement. Specifically, the clamping mechanism includes a fixed connecting frame 541, a pushing cylinder 542, and a pushing connecting frame 551. The fixed connecting frame 541 slides along the arc-shaped guide rail 52, and the pushing cylinder 542 is mounted on the fixed connecting frame 541 and drives the pushing connecting frame 551 to slide. Specifically, the piston rod end of the pusher cylinder 542 is fixedly connected to the pusher frame 543, one end of the pusher guide rod 544 is fixedly connected to the pusher frame 543, and the other end of the pusher guide rod 544 is fixedly connected to the pusher connecting frame 551; a fixed guide rod 545 is also fixedly connected to the fixed connecting frame 541, the fixed guide rod 545 passes through the pusher connecting frame 551 and is parallel to the moving direction of the pusher connecting frame 551, and plays a moving guiding role for the pusher connecting frame 551. A cam rod 546 is fixedly connected to a fixed connecting frame 541, and the cam rod 546 passes through a pushing connecting frame 551. A driving block 561 and a driven gear 571 are rotatably connected to the pushing connecting frame 551. A locking groove 562 and an incomplete gear 563 are respectively provided on opposite sides of the driving block 561. The incomplete gear 563 meshes with the driven gear 571. The cam rod 546 is engaged in the locking groove 562 and drives the driving block 561 to rotate. A clamping cylinder 572 is coaxially fixedly connected to the driven gear 571. The clamping fingers 573 are arranged in pairs at the movable end of the clamping cylinder 572. When the pushing cylinder 542 drives the pushing connecting frame 551 to slide, the locking groove 562 engages with different positions of the cam rod 546 and rotates with the position of the cam rod 546, thereby driving the driven gear 571 and the clamping cylinder 572 to rotate through the incomplete gear 563. When the two clamping mechanisms are close together, the space occupied by the two clamping cylinders 572 in the vertical direction is reduced by rotating the two clamping cylinders 572, thereby avoiding interference between the two clamping cylinders 572.

[0033] A glove folding method, using the glove folding device described above, includes the following steps (taking the folding of a pair of gloves as an example): S1. The sleeve mechanism 1 moves sequentially along the sleeve guide rail 21 to the glove sleeve part, and the outer sleeve 14 moves away from the sleeve mounting seat 11 relative to the inner sleeve 15 until the actuating part of the spring piece 143 is in the second position. S2. The operator places the glove to be folded onto the end of the outer sleeve 14 of the sleeve mechanism 1 at a specified position, specifically, so that the glove's cuff is in the sleeve ring 141; S3. The outer sleeve 14 moves toward the sleeve mounting base 11 until the actuating part of the spring piece 143 is in the first position; S4. Inflate the completed glove through the vent 121 on the fixing block 12 until the glove reaches the predetermined pressure, the glove is fully opened, and moves in the direction of separating from the outer sleeve 14 under the action of air pressure until the glove closing ring is engaged with the end of the moving part of the spring piece 143, thus completing the axial limiting of the glove. S5. The paired sleeve mechanisms 1 on the two sleeve sliding mechanisms 2 move synchronously from the glove fitting part to the glove folding part, while the corresponding gathering clamping mechanism 3 on the clamping sliding mechanism 4 moves to the glove folding part and moves coaxially and synchronously with the glove folding parts on both sides. The gloves on the two sleeve mechanisms 1 are stacked in the gathering bracket 326 in sequence. Specifically, the sleeve mounting seat 11 is hinged to the sleeve slide table 23 or fixedly connected to the mounting seat on the sleeve slide table 23. Before the sleeve mechanism 1 and the gathering clamping mechanism 3 reach the coaxial position, the sleeve mounting seat 11 rotates and tilts the inner side upward, causing the glove to be higher than the upper edge of the gathering bracket 326 of the gathering clamping mechanism 3. After reaching the coaxial position, the two sleeve mounting seats 11 are reset in sequence and the gloves are kept horizontal, so that the gloves are stacked in the gathering bracket 326 in sequence. Then the paired sleeve mechanisms 1 keep moving synchronously and move together with the gathering clamping mechanism 3 towards the glove clamping assembly 5. S6. Inhale air from the glove through the vent 121 until the air pressure inside the glove drops below the predetermined air pressure, thereby reducing the space occupied by the glove; S7. The comb 345 closes inwards, bringing the fingers, palm, and wrist of the glove into the internal space of the hinge plate 355. S8. The comb 345 opens outwards relative to each other, and the retracting bracket 326 descends until the upper edge of the comb 345 is lower than the lowest point of the outer circumference of the outer sleeve 14; S9. The outer sleeve 14 moves away from the inner sleeve 15 towards the side away from the sleeve mounting base 11 until the actuating part of the spring piece 143 is in the second position. Under the action of glove tension, the glove wrist detaches from the outer sleeve 14 and moves towards the center of the hinge plate 355 until the glove wrist folds outward and wraps around the outside of the hinge plate 355. At this time, the fingers and palms of the two gloves are overlapped and wrapped inside the glove wrist, as shown. Figure 12 As shown; S10. The hinged plates 355 rotate inward and close together, further folding the glove so that the folded area is further halved, and the ends of the two wrist folds of the folded glove face away from the side of the closing bracket 326. S11. The gathering and clamping mechanism 3 moves to the glove removal assembly 5, where the paired removal fingers 573 clamp the ends of the two wrist folds of the glove, causing the folded glove to detach from the gathering and clamping mechanism 3 and be placed on the conveyor belt or at the next work station.
