Description

Technical Field

[0001] The present invention relates to the technical field of sock pairing, and in particular to a sock pairing device and method. Background Art

[0002] After the socks are sewn and produced, they need to be paired. When pairing, workers first find two socks of the same length, and then insert the needle into the sock openings of the two socks. When workers perform the positioning operation, they encounter the following problems:

[0003] 1. Worker operation will increase the pairing time and reduce the pairing efficiency of socks;

[0004] 2. Workers need to repeatedly press the open card pins, which will cause great pain to their fingers if they do this for a long time.

[0005] 3. When workers press and close the socks, they cannot ensure the tightness and position of each pin, which causes the pins to fall off or become loose during subsequent packaging transfer, causing the two socks to separate. Summary of the Invention

[0017] S1, sock pairing;

[0018] S2. Pairing socks positioning:

[0019] The worker stretches out the two socks and places the openings of the two socks outside the clamping pin pressing assembly. The first clamping plate and the second clamping plate extend into the two socks relative to each other, and the fitting parts of the two socks extend into the clamping pin relative to each other.

[0020] When the foot switch is stepped on, the opening and closing cylinder drives the first clamping plate and the second clamping plate to move closer, the card needle positioning plate passes through the perforation relative to each other, the first clamping plate and the second clamping plate squeeze the card needle to deform and close, and the protrusion of the card needle moves relatively along the guide groove of the card needle positioning plate;

[0025] The driving gear drives the toothed plate to move along the first slide slot, the movable column drives the card pin above it to move, and the guide rod moves along the second slide slot. At the same time, the slider pulls out the traction rope, and the traction rope drives the reel to rotate and compresses the torsion spring. The reel drives the front baffle downward and the rear baffle upward. When the movable column is about to leave the preparation position, the rear baffle faces upward and the front baffle faces downward.

[0029] The present invention provides a socks pairing device. Compared with the prior art, it has the following advantages:

[0030] 1. After selecting a pair of qualified socks, the worker holds the two sock openings with both hands and inserts the fitting parts of the two socks between the first and second clamping plates. The two sock openings are placed in the initial clamping pins. The worker then steps on the starting pedal, and the opening and closing cylinder drives the first and second clamping plates to move inward synchronously, so that the clamping pins close and clamp the sock openings of the two socks, fixing the pair of socks together. The positioning strength can be guaranteed, and no worker clamping is required, which reduces the operation steps and improves the pairing efficiency.

[0031] 2. The pin positioning plate can suspend and position the pin to prevent it from falling before closing. At the same time, during the clamping stage, the pin positioning plate can stop the pin from the top to prevent it from moving upward, ensuring that the clamping part of the pin can fully fit the sock opening; when the first and second splints are close to each other, the pin positioning plate can pass through the perforation, thereby not affecting the completion of the clamping action.

DETAILED DESCRIPTION

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0046] To address the current issues of low efficiency and insufficient clamping during sock pairing, the following design is proposed:

[0047] like Figure 1 and Figure 2 As shown, a sock pairing device includes a conveyor belt 1, the surface of the conveyor belt 1 is evenly provided with support components 2, the assembly of the support components 2 is connected to the sock plate 3, and a card needle pressing component 4 is installed above the conveyor belt 1; the card needle pressing component 4 includes an opening and closing cylinder 41, a first clamping plate 42, a second clamping plate 43, and a card needle positioning plate 44; the top surface of the opening and closing cylinder 41 is installed with a lifting pneumatic rod 10, the bottom surface of one movable end of the opening and closing cylinder 41 is vertically connected to the first clamping plate 42, and the bottom surface of the other movable end is vertically connected to the second clamping plate 43, the first clamping plate 42 and the second clamping plate 43 are arranged parallel to each other, and the inner wall of the first clamping plate 42 is vertically provided with a rectangular The long structure of the card needle positioning plate 44, the interior of the second clamping plate 43 is provided with a through hole 431 for the card needle positioning plate 44 to pass through; the lifting pneumatic rod 10 is used to drive the card needle clamping assembly 4 to move upward to the loading position and downward to the clamping position. The card needle loading assembly 7 is installed at the loading position. The card needle loading assembly 7 is used to automatically transfer the card needles 6 one by one to the bottom of the card needle positioning plate 44. The card needle 6 in the initial state is an inverted V-shape and the top end is a rounded structure; the card needle 6 that is not fully closed is suspended under the card needle positioning plate 44, and the first clamping plate 42 and the second clamping plate 43 that are close to each other are used to close and clamp the card needle 6 at the sock opening of a pair of socks.

[0048] After selecting a pair of qualified socks, the worker holds the two sock openings with both hands, and inserts the fitting parts of the two socks between the first clamping plate 42 and the second clamping plate 43. The two sock openings are placed in the initial state of the clamping needle 6. Then the opening and closing cylinder 41 is activated to drive the first clamping plate 42 and the second clamping plate 43 to move inward synchronously, so that the clamping needle 6 closes and clamps the sock openings of the two socks. Figure 11 As shown, by fixing a pair of socks together, the positioning strength can be guaranteed, without the need for workers to clamp them, reducing the number of operation steps and improving pairing efficiency;

[0049] The needle loading assembly 7 can be used to fill the needles 6 one by one to the bottom of the needle positioning plate 44 to achieve automatic feeding. The needle positioning plate 44 can suspend and position the needles 6 to prevent the needles 6 from falling before closing. At the same time, in the clamping stage, the needle positioning plate 44 can stop the needles 6 from the top to prevent the needles 6 from moving upward, ensuring that the clamping part of the needles 6 can fully fit the sock opening; when the first clamping plate 42 and the second clamping plate 43 are close to each other, the needle positioning plate 44 can pass through the perforation 431, thereby not affecting the completion of the clamping action.

[0050] In order to ensure that the pin positioning plate 44 does not affect the clamping action and meet the needs of automatic processing, the pin positioning plate 44 needs to solve the following problems at the same time: the pin 6 can enter the pin positioning plate 44 during loading, the pin 6 can slide relative to the pin positioning plate 44 during clamping, and the pin 6 can be separated from the pin positioning plate 44 after clamping. To this end, the present application provides the following design:

[0051] like Figure 3 and Figure 4 As shown, an L-shaped receiving groove is provided on the bottom surface of the needle positioning plate 44, and the bottom surface of the receiving groove is an open structure. The receiving groove is composed of a feed groove 441, a guide groove 442, and a discharge groove 443 connected in sequence. The feed groove 441 is the longitudinal part of the receiving groove, and the guide groove 442 and the discharge groove 443 are the transverse parts of the receiving groove. A protrusion 61 is provided at the center of the top surface of the needle 6, and the protrusion 61 is engaged and embedded in the feed groove 441 and the guide groove 442, and the discharge groove 443 is a vertical flat structure.

[0052] By designing a convex-shaped protrusion 61 at the top of the card needle 6, the feed groove 441 and the guide groove 442 are both groove structures adapted to the protrusion 61, so that the feed groove 441 and the guide groove 442 can stop and position the protrusion 61, so that the card needle 6 can be suspended and positioned below the card needle positioning plate 44, and the card needle 6 and the card needle positioning plate 44 can slide relative to each other;

[0053] The feed slot 441 is the entry part of the card needle 6. The card needle loading assembly 7 can push the protrusion 61 into the connection between the feed slot 441 and the guide slot 442. After loading to this position, the subsequent translational movement of the card needle positioning plate 44 can proceed smoothly; when the first clamping plate 42 and the second clamping plate 43 are close to each other, the protrusion 61 moves relatively along the guide slot 442; when clamping is completed, the protrusion 61 can be moved to the flat outlet slot 443. At this time, the card needle positioning plate 44 is lifted up, and the clamped card needle 6 can be separated from the card needle positioning plate 44.

[0054] Because the card needle 6 is small in size and very light in weight, the card needle feeding assembly 7 needs to solve the following problems before realizing the automatic feeding function: how to support the card needle 6, how to push the card needle 6 to feed the material, and how to transfer the card needle 6 to the connection between the feed groove 441 and the guide groove 442. To this end, the present application provides the following design:

[0055] like Figure 5 and Figure 6 As shown, the needle loading assembly 7 includes a storage column 71, a movable column 72, a fixed plate 73, a loading cylinder 74 and a telescopic drive member.

[0056] A storage column 71 and a loading cylinder 74 are vertically mounted on the inner wall of the fixed plate 73. The loading cylinder 74 is positioned parallel and spaced above the storage column 71. A push plate 741 is mounted at the output end of the loading cylinder 74. The bottom end of the push plate 741 abuts against the upper surface of the storage column 71. Multiple card pins 6 are suspended in a linear array on the storage column 71. The storage column 71 has a built-in telescopic drive component. A movable column 72 is mounted at the output end of the storage column 71. The loading cylinder 74 is used to push the card pins 6 placed on the storage column 71 one by one onto the movable column 72. The telescopic drive component is used to drive the movable column 72 to move below the card pin positioning plate 44, thereby causing the protrusion 61 of the card pin 6 to snap into the receiving groove. The movable column 72 and the storage column 71 are located on the same axis. The outer diameter of the movable column 72 is the same as that of the storage column 71, and the width of the movable column 72 is the same as that of the card pin 6.

[0057] The storage column 71 and the movable column 72 are both round rod structures. Each inverted V-shaped card pin 6 can be hung on the storage column 71 in turn, and workers can load materials in rows; because the card pin positioning plate 44 needs to move downward, the storage column 71 cannot extend to the bottom of the card pin positioning plate 44, and a single card pin 6 needs to be driven by the reciprocating movable column 72 to load the material, thereby loading the protrusion 61 to the connection between the feed groove 441 and the guide groove 442; the loading cylinder 74 drives the push plate 741 to move forward, thereby pushing a card pin 6 to be added to the movable column 72; the size design of the movable column 72 can ensure that only one card pin 6 can be stably loaded at a time.

[0058] Since the size of the card needle 6 is very small, the length of the movable column 72, the feed trough 441, and the guide trough 442 are all small. The installation space of traditional pneumatic rods, electric push rods, etc. is limited. In order to achieve high-precision loading, the following design of the telescopic drive component is given:

[0059] The telescopic driving member includes a guide rod 75, a tooth plate 76, and a driving gear 77. The interior of the storage column 71 is provided with a first slide groove 711 and a second slide groove 712 with open ends. The first slide groove 711, the second slide groove 712, and the third slide groove 713 are distributed in sequence from bottom to top; the guide rod 75 and the tooth plate 76 are both vertically arranged on the side wall of the movable column 72, the guide rod 75 slides and is embedded in the second slide groove 712, and the tooth plate 76 slides and is embedded in the first slide groove 711. The bottom surface of the storage column 71 is provided with a driving motor, and the output end of the driving motor is provided with a driving gear 77. The driving gear 77 extends into the first slide groove 711 and engages with the tooth plate 76.

[0060] Through the cooperation of the driving gear 77 and the tooth plate 76, reciprocating feed drive can be achieved. The adjustment range of the gear and the tooth plate 76 is more precise, and the design of the guide rod 75 can improve the stability of the reciprocating motion.

[0061] When the clamping pin 6 on the movable column 72 is driven to feed the material by the telescopic driving member, since the clamping pin 6 is very light, when the protrusion 61 of the clamping pin 6 enters the feed groove 441 and the guide groove 442, the clamping pin 6 lacks the propulsion force to overcome the friction of the feed groove 441 and the guide groove 442, so that the final entry position of the clamping pin 6 may be deviated. In order to solve the above problem, the following structural design is provided:

[0062] like Figure 5-Figure 7 As shown, a horizontally distributed rotating groove is opened at the internal top of the movable column 72, and a card needle stop assembly 9 is rotatably installed inside the rotating groove. The card needle stop assembly 9 includes a front baffle 91, a rear baffle 92, a winding wheel 93, and a transmission rod 94; the transmission rod 94 rotates through the rotating groove, and the front extended end of the transmission rod 94 is provided with a front baffle 91, and the rear extended end is provided with a rear baffle 92. The front baffle 91 and the rear baffle 92 are both T-shaped and have opposite protrusions. The front baffle 91 and the rear baffle 92 are alternately extended upwards toward the movable column 72, and the upward front baffle 91 is used to stop the card needle 6 from the front, and the upward rear baffle 92 is used to push the card needle 6 from the rear. A winding wheel 93 is provided in the middle of the outer wall of the transmission rod 94, and a middle groove 721 is opened in the middle of the rotating groove for the winding wheel 93 to be embedded. The outside of the winding wheel 93 is connected to the flip drive assembly 8, and the flip drive assembly 8 is used to drive the winding wheel 93 to rotate.

[0063] Only one of the front baffle 91 and the rear baffle 92 of the T-shaped plate, which are in opposite directions, always faces upward;

[0064] In this way, when the feeding cylinder 74 pushes the material, the front baffle 91 faces upward. In this way, when the pushing plate 741 pushes the multiple card pins 6 to move forward, the card pins 6 at the front stop with the front baffle 91, which means they are transported into place, thereby preventing the card pins 6 from being over-fed and ensuring the accuracy of the card pins 6 entering the movable column 72.

[0065] When the movable column 72 is loading, in order to overcome the friction resistance and ensure that the card needle 6 stably enters the specified position of the movable column 72, the flip drive assembly 8 drives the rear baffle 92 upward. In this way, when the movable column 72 moves, the rear baffle 92 can push the protrusion 61 from the outside to overcome the friction resistance, so that the card needle 6 enters the specified position with high precision.

[0066] The needle loading assembly 7 is spaced apart from the needle positioning plate 44 in the loading position, and the spaced area is a preparation station, so that the needle stop assembly 9 can be rotated into position at the preparation station. In this way, when entering the feed trough 441 and the guide trough 442 stage, the needle stop assembly 9 will no longer move.

[0067] In order to enable the flip drive assembly 8 to realize the rotation of the transmission rod 94 at a specified position, and to solve the problem that the movable column 72 is small and a traditional motor cannot be installed to drive the transmission rod 94 to rotate, the following structural design is provided:

[0068] like Figure 5-Figure 7 As shown, the flip drive assembly 8 includes a slider 81, a spring 82, and a traction rope 83; a wire groove 722 is provided on the outer wall of the movable column 72, and the wire groove 722 is horizontally and vertically connected to the middle groove 721, and a torsion spring is installed between the winding wheel 93 and the middle groove 721. One end of the traction rope 83 is wrapped around the winding wheel 93, and the other end passes through the wire groove 722 and the end is connected to the slider 81. The exposed traction rope 83 is placed parallel to the outside of the movable column 72 and the storage column 71, and a horizontally distributed third slide groove 713 is provided on the side wall of the storage column 71. The slider 81 is slidably embedded in the third slide groove 713, and a spring 82 is embedded in the inside of the third slide groove 713. The spring 82 is provided on the other side of the slider 81 away from the traction rope 83, and the deformation tension of the spring 82 is greater than the deformation tension of the torsion spring.

[0069] The reel 93 is connected to the torsion spring in the middle groove 721, so that the torsion spring can drive the reel 93 to rotate and reset; the deformation tension of the torsion spring is greater than the deformation tension of the spring 82, so that when the movable column 72 moves to the preparation position, the traction rope 83 leaves the reel 93 and drives the reel 93 to rotate and compress the torsion spring. At this stage, due to the large tension required by the spring 82, the spring 82 does not move; when the needle stop assembly 9 rotates into place and the movable column 72 leaves the preparation position, the torsion spring is compressed to the limit and the traction rope 83 cannot be pulled out. As the movable column 72 moves, the traction rope 83 drives the slider 81 to move along the third slide groove 713 and stretch the spring 82;

[0070] Thus, in the preparation position, the spring 82 applies a reverse pulling force to the traction rope 83, causing the slider 81 to pull out the traction rope 83, thereby driving the card needle stop assembly 9 to rotate and transform; and when the transformation action is completed, the slider 81 can move and always maintain the pulling force on the card needle stop assembly 9, preventing the card needle stop assembly 9 from resetting and rotating, and keeping the rear baffle 92 facing upward;

[0071] When the movable column 72 is reset, the spring 82 first drives the slider 81 to reset, and then the torsion spring drives the traction rope 83 to reset.

[0072] The above design ensures that the rear baffle 92 has been rotated upward before the card needle 6 enters the card needle positioning plate 44, and the rear baffle 92 always remains in an upward state during the process of the card needle 6 entering the storage slot, thereby ensuring that the card needle 6 can move into position accurately;

[0073] When the movable column 72 is reset, the front baffle 91 can automatically rotate upward and the rear baffle 92 can rotate downward, thereby preparing for the next material replenishment.

[0074] In order to help workers quickly understand whether the sock length meets the standard, the following structural design is given:

[0075] like Figure 10As shown, support assemblies 2 are provided at intervals on the surface of the conveyor belt 1. The support assembly 2 includes a base 21, an inner block rod 22, and an outer block rod 22. A groove is provided in the base 21. The inner block rod 22 and the outer block rod 22 are mirror-symmetrically provided inside the groove. The inner block rod 22 and the outer block rod 22 are in an inverted T shape. The inner block rod 22 and the outer block rod 22 are inclined outward at 45 degrees. The middle part of the groove is rotatably connected to the sock plate 3, and the surface of the sock plate 3 is provided with a sock length scale bar 31.

[0076] Through the design of the inner and outer stop rods 22, when putting on socks, the sock plate 3 and the outer stop rod 22 are in contact with the stop, and are closer to the workers, making it easier for the workers to put on socks. After putting on the socks, the sock plate 3 is rotated so that the sock plate 3 and the inner stop rod 22 are in contact with the stop. In this way, during the positioning process, the sock plate 3 has a larger inclination angle to show the position of the sock opening on the sock length scale bar 31. The workers can quickly judge the length of the socks when they are delivered, and thus quickly match a pair of socks.

[0077] In summary, the overall working method of the embodiment provided in this application includes the following steps:

[0078] S1. Socks pairing:

[0079] The sock plate 3 is fitted with the outer stop rod 22 and is conveyed by the conveyor belt 1 to the sock-putting station. The worker puts the socks on the sock plate 3 and then rotates the sock plate 3 inward so that the sock plate 3 is fitted with the inner stop rod 22;

[0080] The conveyor belt 1 transports the socks to the positioning station. The worker quickly knows the sock length through the sock length scale bar 31 and takes out two socks of the same length to pair them up.

[0081] S2. Pairing socks positioning:

[0082] The worker stretches out the two socks and places the openings of the two socks outside the clamping needle pressing assembly 4. The first clamping plate 42 and the second clamping plate 43 extend into the two socks relative to each other, and the fitting parts of the two socks extend into the clamping needle 6 relative to each other.

[0083] The worker steps on the foot switch, and the opening and closing cylinder 41 drives the first clamping plate 42 and the second clamping plate 43 to move closer. The clamping pin positioning plate 44 passes through the through-hole 431. The first clamping plate 42 and the second clamping plate 43 squeeze the clamping pin 6 to deform and close. The protrusion 61 of the clamping pin 6 moves relatively along the guide groove of the clamping pin positioning plate 44.

[0084] When the first clamping plate 42 and the second clamping plate 43 are brought close to the limit, the clamping pin 6 is completely closed and locks the two socks, and the protrusion 61 moves relatively to the discharge slot 443;

[0085] The lifting pneumatic rod 10 drives the opening and closing cylinder 41 to move upward to the loading position, the clamping needle 6 is separated from the fixing plate 73, and the paired socks can be positioned and removed;

[0086] S3, automatic refilling of needle 6;

[0087] like Figure 5 As shown, the loading cylinder 74 pushes the card pin 6 on the storage column 71 onto the movable column 72 until the card pin 6 contacts the front baffle 91;

[0088] like Figure 8 As shown, the driving gear 77 drives the toothed plate 76 to move along the first sliding groove 711, the movable column 72 drives the card needle 6 above it to move, and the guide rod 75 moves along the second sliding groove 712. At the same time, the slider 81 pulls out the traction rope 83, and the traction rope 83 drives the winding wheel 93 to rotate and compress the torsion spring. The winding wheel 93 drives the front baffle 91 downward and the rear baffle 92 upward. When the movable column 72 is about to leave the preparation position, the rear baffle 92 faces upward and the front baffle 91 faces downward, the torsion spring is compressed to the limit, and the traction rope 83 is stretched to the maximum length.

[0089] like Figure 9 As shown, the driving gear 77 drives the movable column 72 to move to the bottom of the card needle positioning plate 44, the protrusion 61 of the card needle 6 enters the feed slot 441, the slider 81 moves along the first slide slot 711 and stretches the spring 82; the rear baffle 92 pushes the protrusion 61 to overcome the resistance, and the protrusion 61 stops when it moves to the connection between the feed slot 441 and the guide slot 442;

[0090] The driving gear 77 rotates in reverse, driving the movable column 72 to reset, the spring 82 drives the slider 81 to reset, and the torsion spring drives the winding wheel 93 to rotate and reset;

[0091] The lifting pneumatic rod 10 drives the opening and closing cylinder 41 to descend to the initial state.
