As people's living standards and quality of life improve year by year, their demand for socks has shifted from quantity to quality. Socks are circulated in the market after processes such as knitting, sewing, turning, shaping, attaching sock tags, and packaging. The attachment of sock tags and packaging, as the final two steps in the sock manufacturing process, not only enhance the socks' appearance and added value but also protect them and facilitate transportation and storage. Currently, most sock manufacturers rely heavily on manual packaging, resulting in long working hours, high intensity, low efficiency, and packaging quality that depends primarily on manual experience, making it difficult to control product quality and leading to a decline in overall product quality. Existing technologies also provide equipment for automating sock tag installation and packaging.

The two sock clip clamping rods can move synchronously towards and away from each other in the left-right direction (driven by a corresponding structure), and they can move synchronously vertically (driven by a corresponding structure). They are located on the left and right sides of the sock clip, respectively, and the upper side of their adjacent ends has a clearance notch that cooperates with the hook. The sock clip clamping rod is arranged in the left-right direction and is located adjacent to the front of the sock 13, at the folding part of the sock clip. The worktable 1 has short, horizontal slots along its left and right sides to accommodate the sock clamping rods. The two sock clamping rods first move upwards, then towards each other, and then downwards to clamp the socks. At this time, the two sock clamping rods are pressed together (located above the adjacent socks) and located behind the adjacent lifting block 72.

[0027] When the sock card is flipped, the sock card clamping assembly 74 clamps the sock card. The feeding gripper 71 (first moves to the right to the sock feeding device 11, clamps the sock 13, then moves to the left to the sock card flipping station, releases, and the sock 13 falls onto the worktable 1, then continues to move to the left side of the sock) feeds the sock 13. After feeding the sock 13, the lifting block 72 rises (the rising height is 5-15mm), the front part of the sock card tilts upward, and the push rod 73 moves backward and downward to the front end of the sock 13 (pushing the front part of the sock card), pressing the front part of the sock card against the front part of the sock 13. After the sock card is flipped, the right feeding clamp 8 moves to the left, clamping the sock card and the sock 13 together. At this time, the right feeding clamp 8 is located between the feeding gripper 71 and the sock card clamping assembly 74, and it clamps the right part of the sock 13. The lifting block 72 and the sock clamping assembly 74 return to their original positions, and the right feeding clamp 8 moves forward to feed the material.

[0028] The sock labeling device is consistent with existing technology and is used to sew the sock card and sock 13 together.

[0029] The reversing device 2 can move left and right, and is used to flip the sock 13 180° in the front-to-back direction. It can move to the right to the sewing station and transfer the sock 13 from the sewing station to the reversing station. It includes a reversing bracket 21, a lateral translation structure, a fixed arm, a flipping structure 22, and reversing grippers. The reversing bracket 21 is set on the workbench 1 in the left-to-right direction and is located behind the sewing station. The lateral translation structure is set on the reversing bracket 21 and can move left and right. The fixed arm is set on the lateral translation structure, is set vertically, and is located below the lateral translation structure. The flipping structure 22 is located below the fixed arm and is specifically a rotary cylinder that can rotate 180°. The reversing gripper is located on the right side of the flipping structure 22. It is a pneumatic gripper, arranged in the front-to-back direction, and positioned below and in front of the reversing bracket 21. It includes an upper clamping plate 23 and a lower clamping plate 24 arranged side by side and driven synchronously. It is designed to avoid being positioned relative to the left feeding clamp 31. The upper clamping plate 23 and the lower clamping plate 24 can move synchronously towards and away from each other in the vertical direction, and they are both arranged horizontally in the front-to-back direction. The worktable 1 is provided with a long horizontal slot 25 for the fixed arm and the flipping structure 22 to pass through and move in the left and right directions. The long horizontal slot 25 is arranged in the left and right direction, and its left end is provided with a flipping hole 26 for the reversing device 2 to flip.

[0030] The relay feeding device 3 includes a left feeding clamp 31 and a bagging clamp 32. The left feeding clamp 31 and the bagging clamp 32 are located directly in front of and directly behind the reversing device 2, respectively. Both the bagging clamp 32 and the left feeding clamp 31 are arranged in the front-back direction and can move in both directions. They each include an upper clamping arm and a lower clamping arm arranged side-by-side. The upper and lower clamping arms are both arranged in the front-back direction. The left feeding clamp 31 is used to feed the socks 13 from the reversing device 2 to the handover station, and the bagging clamp 32 is used to feed the socks 13 from the handover station to the bagging station and put the socks 13 into the packaging bag 12. When the left feeding clamp 31 is located at the handover station, it is behind the reversing device 2 and adjacent to the front of the bagging clamp 32. The workbench 1 is provided with a wide longitudinal strip hole 33 through which the lower clamping arms of both the left feeding clamp 31 and the bagging clamp 32 pass and move back and forth. The wide longitudinal strip hole 33 is arranged in the back and forth direction and its front end is connected to the flipping hole 26. The lower clamping arm is located in the wide longitudinal strip hole 33 and can move up and down.

[0031] The bagging device 4 includes a lower pressing structure 41, a bag opening structure 42, and an upper pressing structure 43. The lower pressing structure 41 is located on the worktable 1 and presses the front end of the lower bag surface of the packaging bag 12 onto the worktable 1. It includes two L-shaped pressure plates arranged side-by-side and driven synchronously. The two L-shaped pressure plates are located on the left and right sides of the bagging clamp 32, respectively pressing the left and right parts of the lower bag surface. The L-shaped pressure plates can move vertically (driven by a corresponding structure, specifically a cylinder), and their upper parts bend backward to form a pressing part, which is arranged in the front-back direction and located directly above the front end of the lower bag surface. The bag opening structure 42 includes a bag opening bracket, a bag opening cylinder, and a bag opening plate. The bag opening bracket is located on the worktable 1 and is an L-shaped frame or a gantry frame, etc. The bag opening cylinder is located on the bag opening bracket and is arranged diagonally downward from front to back. The bag-opening plate is a flexible, thin metal plate fixed to the lower end of the telescopic rod of the bag-opening cylinder. It is angled downwards from front to back (the angle of inclination is approximately the same as the angle of the bag-opening cylinder), with its lower part curved backwards. Its lower end is located directly above the pressing part and above the front of the upper surface of the packaging bag 12, allowing it to be inserted backwards into the packaging bag 12. When the bag-opening cylinder extends, the lower end of the bag-opening plate is inserted into the packaging bag 12. The bag-opening plate serves at least three functions: first, it forms a funnel-shaped opening to guide the sock 13 into the packaging bag 12; second, it opens the front end of the packaging bag 12 when the upper clamping arm (specifically, the rear upper clamping arm) strikes the bag-opening plate; and third, it presses down the upper clamping arm (specifically, the rear upper clamping arm) to ensure the clamping effect of the bag-filling clamp 32. The upper pressing structure 43 can move up and down (driven by a corresponding structure, specifically a cylinder) and includes two pressing blocks 44 arranged side by side and driven synchronously. The two pressing blocks 44 are located directly above the left and right ends of the sock 13 and are located on the left and right sides of the bagging clamp 32 (specifically a clamping arm).

[0032] During bagging, the packaging bag 12 is delivered to the bagging station by the bag-making device. The lower pressing structure 41 moves downward to first press the packaging bag 12, and then the bag opening plate moves obliquely backward to insert into the packaging bag 12. The bagging clamp 32 moves backward (the two clamping arms clamp the sock 13) and passes under the bag opening plate. At this time, the upper pressing structure 43 is in a high position, and the lower end of the bag opening plate presses against the upper side of the upper clamping arms of the bagging clamp 32. After the sock 13 is fed into the packaging bag 12, the upper pressing structure 43 moves downward to press the left and right ends of the sock 13 to prevent the sock 13 from following the bagging clamp 32. The bagging clamp 32 returns to its original position, and at the same time, the bag opening plate returns to its original position.

[0033] The sealing device 5 includes a sealing clamp 51 and a sealing structure at the sealing station. The sealing clamp 51 can move back and forth (driven by a corresponding structure) and is used to transfer the packaging bag 12 from the bagging station to the sealing station. Specifically, it clamps the front of the packaging bag 12 and is located on the right side of the packaging bag 12. The sealing structure includes a lifting plate 52, a sealing plate 53, a pressure plate 54, and a folding rod 55. The lifting plate 52, sealing plate 53, pressure plate 54, and folding rod 55 are all arranged in the left and right direction. The lifting plate 52, sealing plate 53, and pressure plate 54 are all horizontally arranged rectangular plates, and the folding rod 55 is a round rod with a diameter of less than 4 mm. The lifting plate 52 is located on the workbench 1 and can move up and down (driven by a corresponding structure, specifically a cylinder). It is flush with the workbench 1 and located directly below the sealing part of the packaging bag 12. The sealing plate 53 is located above and in front of the lifting plate 52. It can move vertically and forward and backward (driven by a corresponding structure, specifically a cylinder assembly). A soft body 56 is provided on its lower side for sealing the packaging bag 12. The pressure plate 54 is located directly above the front of the packaging bag 12 and above and behind the lifting plate 52. It can move up and down (driven by a corresponding structure, specifically a cylinder) for pressing the packaging bag 12. A strip-shaped soft block is provided on its lower side. The lower side of the soft body 56 is angled downward from back to front. The folding rod 55 can move left and right and vertically (driven by a corresponding structure). It is located on the left side of the lifting plate 52 (and also on the left side of the packaging bag 12). Its right end is a free end, and its left end is connected to the corresponding driving structure. It is located above the packaging bag 12 and can move to the right and downward to the adjacent rear of the lifting plate 52.

[0034] During sealing, the pressure plate 54 descends to press the packaging bag 12 tightly, and the folding rod 55 moves to the right and downward to the adjacent rear of the lifting plate 52. The lifting plate 52 rises to make the sealing part tilt upward. The sealing plate 53 moves backward and downward between the lifting plate and the pressure plate to seal (at this time, the sealing plate 53 presses against the upper side of the sealing part). When the sealing plate 53 moves backward, it rests against the front side of the sealing part.

[0035] The discharge device 6 includes a suction cup assembly 61 and a discharge conveyor belt. The discharge conveyor belt is located below the workbench 1. A discharge perforation 62 (specifically a rectangular hole arranged in the front-back direction, allowing the product to pass downwards) is provided on the workbench 1 directly above the feed end of the discharge conveyor belt. The suction cup assembly 61 can move in the front-back and vertical directions (driven by a corresponding structure). It is located adjacent to and behind the pressure plate 54, directly above the middle and rear of the packaging bag 12. It can transfer the packaging bag 12 from the sealing station to the discharge station, specifically located on the left side of the packaging bag 12.

[0036] Example 2 See Figure 4-6Example 2 provides an automated system for installing sock clips and packaging socks.

The two rectangular plates are located directly above the left and right sides of the sock 13, respectively. The rectangular plates are arranged in a front-to-back direction and have multiple perforated holes (specifically, round holes) arranged side-by-side. The U-shaped arched portion allows the upper clamping arm (specifically, the front upper clamping arm) of the left feeding clamp 31 to pass through for clearance design. The lower clamping plate 24 is located directly below the front of the upper clamping plate 23, directly below the left side of the sock 13, and to the left of the left feeding clamp 31 (specifically, the clamping arm) for clearance design. It is a U-shaped plate opening to the right.

Its structure is basically the same as that of Example 2, except that the left-feeding clamp 31 in this example includes a lower longitudinal moving structure, a feeding bracket, and a front pneumatic gripper. The lower longitudinal moving structure is arranged in the front-back direction, located below the worktable 1, directly opposite the wide longitudinal strip hole 33, and can move back and forth (driven by a corresponding structure). The feeding bracket is located on the lower longitudinal moving structure, vertically positioned, and can move back and forth within the flip hole 26. It bends to the right at the upper clamping plate 23 to avoid it. The front pneumatic gripper is located above the feeding bracket, and has a front upper clamping arm and a front lower clamping arm on its rear side. The front upper clamping arm and the front lower clamping arm are arranged side-by-side, vertically, and can move synchronously towards and away from each other in the vertical direction.

The front upper clamping arm can pass through the U-shaped arch.

[0038] The bagging fixture 32 includes a right longitudinal moving structure, a rear pneumatic gripper, and a bagging L-shaped plate. The right longitudinal moving structure is positioned along the front-to-back direction and is located on the lower side of the worktable 1, to the right of the wide longitudinal slot 33. It can move forward and backward (driven by a corresponding structure). The rear pneumatic gripper is mounted on the right longitudinal moving structure, and to its left are an upper rear gripper arm and a lower rear gripper arm capable of vertical movement. The upper and lower rear grippers are arranged side-by-side, moving synchronously towards and away from each other in the vertical direction. They are both positioned along the front-to-back direction, located directly above and below the wide longitudinal slot 33, respectively. The front end of the upper rear gripper arm is connected to the rear pneumatic gripper via the bagging L-shaped plate. The bagging L-shaped plate is vertically positioned, with its lower end connected to the rear pneumatic gripper. It can move vertically and forward and backward within the narrow longitudinal slot 34, and its upper part extends upward through the worktable 1 and bends to the left to form a transverse arm. The left end of the horizontal arm is fixedly connected to the front end of the rear upper clamping arm. The worktable 1 is provided with a narrow longitudinal strip hole 34 for the L-shaped plate for bagging to pass through and move in the front-back direction. The narrow longitudinal strip hole 34 is arranged in the front-back direction and is located on the right side of the sock 13. Its width is smaller than that of the wide longitudinal strip hole 33.

[0039] Example 4 See Figure 9 Example 4 provides an automated system for installing sock tags and packaging socks. Its structure is basically the same as that of Example 1, except that the pressing block 44 in this example is a soft right-angled trapezoidal block, and the side of the two pressing blocks 44 that are close to each other is sloping and gradually moves away from each other from top to bottom. Specifically, the pressing block 44, the strip-shaped soft block, and the soft body 56 are all sponge blocks.

[0040] Example 5 See Figure 3 Example 5 provides an automated system for installing sock tags and packaging socks. Its structure is basically the same as that of Example 1, except that: in this example, the workbench 1 has a clearance notch 77 (opening to the right) on its right side. The clearance notch 77 is located directly below the right feeding clamp 8 at the sock tag folding station and contains a lifting support plate 78. The lifting support plate 78 is horizontally positioned, flush with the workbench 1, and can move up and down (driven by a corresponding structure). Its upper surface is smooth, and it is located in front of the movement trajectory of the feeding gripper 71 to avoid affecting the feeding gripper 71. When the right feeding clamp 8 is at the sock tag folding station, the lifting support plate 78 descends to ensure the right feeding clamp 8 can move (specifically, open).

[0041] Example 6 Example 6 provides an automated system for installing sock tags and packaging socks. Its structure is basically the same as that of Example 1, except that the width of the clamping arm of the left feeding clamp 31 in this example is smaller than the width of the clamping arm of the bagging clamp 32, and the clamping arm of the bagging clamp 32 clamps the middle of the sock 13 and its thickness is less than 3mm.

[0042] Example 7 Example 7 provides a method for automating the installation of sock tags and packaging of socks. The method includes: sequentially performing the following processes along the conveying direction of the sock tags: sock tag feeding, hook installation, sock tag folding, sewing, translation and reversal, handover, bagging, sealing and unloading. The hook installation process may or may not be performed.

[0043] In the translation and reversing process: the reversing device transfers the socks 13 from the sewing station to the reversing station and flips the socks 13 180° in the front and back directions.

[0044] In the handover process: the left feeding clamp sends the socks 13 from the reversing station to the handover station, and the bagging clamp sends the socks 13 from the handover station to the bagging station and puts the socks 13 into the packaging bag 12.

[0045] In the bagging process: the packaging bag 12 is delivered to the bagging station by the bag-making device. The lower clamping structure first clamps the packaging bag 12, and then the bag-opening plate moves obliquely backward to insert into the packaging bag 12. The bagging clamp moves backward and passes under the bag-opening plate. At this time, the upper clamping structure is in a high position, and the lower end of the bag-opening plate presses against the upper side of the upper clamping arm of the bagging clamp. After the sock 13 is fed into the packaging bag 12, the upper clamping structure moves downward to clamp the left and right ends of the sock 13. The bagging clamp returns to its original position, and at the same time, the bag-opening plate returns to its original position.

[0046] In the sealing process, the pressure plate presses the packaging bag 12 tightly, the folding rod moves to the right and down to the adjacent rear of the lifting plate, the lifting plate rises to make the sealing part curl upwards; the sealing plate moves backwards and downwards to seal.

[0047] Example 8 Example 8 provides a method for automating the installation of sock tags and packaging of socks. If the hook installation device is not working (i.e., no hooks are installed on the sock tags), then the hook installation station is equivalent to an empty station.

[0048] Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
