Description

Technical Field

[0001] The invention relates to socks production equipment, in particular to socks shaping and folding equipment. Background Art

[0002] After knitted hosiery is woven, it needs to go through multiple processes such as flattening, folding, and packaging. Each process is usually completed in an independent workstation or workshop, so materials need to be circulated between each process. After weaving, knitted hosiery is usually piled in a disorderly manner in material boxes or bags, and its texture is soft. In order to prevent the materials from being disturbed by external forces such as vibration during the flattening process and transported to the folding station, heat setting is usually used to set and flatten the knitted hosiery after weaving. Before this, manual sorting and sorting are required so that they can be sent to the setting machine for heat setting.

[0020] 4. By setting up a return channel, the socks that have not been taken away from the discharge end of the conveyor belt can be recovered in time to avoid the socks piling up in the next process and affecting the working sequence of the entire production line.

[0021] 5. By setting a leveling cylinder with a horizontally arranged piston rod and rotating the sock pressing roller on the sock pressing frame, when the sock pressing roller presses the socks tightly against the conveying surface, the belt conveyor mechanism does not need to stop conveying.

[0022] 6. By setting up the socks swinging mechanism, the socks can be placed in pairs before folding, which effectively improves production efficiency.

[0089] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0090] like Figure 1 As described above, this embodiment provides a sock shaping and folding device, which includes a turning and feeding device 100, a sock opening flattening device 200 and a sock placing and folding device 300 connected in sequence.

[0091] The flip feeding device 100 is a device that uses a flipping action to achieve feeding. It can adopt an existing device, for example, a sock flipping device disclosed in the Chinese utility model patent with publication number CN217349686U is used in conjunction with an existing multi-joint serial robot to form a flip feeding device 100. When in use, the socks are directly poured into the flip frame of the flip feeding device 100, and the flipping action of the flip frame is used to place the socks on the top. Then, the multi-joint serial robot is used to clamp the socks to the next station to achieve feeding. Figure 2-Figure 5 As shown, the flip feeding device 100 provided in this embodiment includes a conveyor frame 110, a flip sock storage mechanism 160, an active rod 111 and a driven rod 112 respectively connected to the conveyor frame 110, a conveyor belt 113 wound between the active rod 111 and the driven rod 112, and a conveyor motor 114 for driving the active rod 111 to rotate. The specific transmission connection structure between the conveyor motor 114 and the active rod 111 can be a conventional structure, such as a belt drive or a chain drive, which will not be described in detail here. The conveyor belt 113 forms a conveying section between the active rod 111 and the driven rod 112 and a circulation section located below the conveying section. The upper side of the conveying section forms a conveying surface, one end of the conveying surface serves as a feed end, and the other end serves as a discharge end.

[0092] Preferably, the flip feeding device 100 provided in this embodiment further includes a scattering assembly 120 located above the conveying surface of the conveyor belt 113. Specifically, the scattering assembly 120 is located between the feed end and the discharge end of the conveyor belt 113. The conveyor frame 110, the active rod 111 and the driven rod 112, the conveyor belt 113, the conveying motor 114, and the scattering assembly 120 collectively constitute a sock pile scattering conveying mechanism.

[0093] The disintegration assembly 120 includes an inclined slide rod 121 fixedly connected to the conveyor frame 110 directly or indirectly, an inclined slide seat 122 slidably connected to the inclined slide rod 121, an inclined slide cylinder 123 for driving the inclined slide seat 122 to slide, two transverse shifting seats 124 respectively connected to the inclined slide seat 122 in a horizontal sliding manner, a transverse shifting cylinder 125 respectively matched with each transverse shifting seat 124 in a one-to-one manner, and a clamping plate 126 respectively fixedly connected to the piston rod of each transverse shifting cylinder 125, wherein the inclined slide rod 121 It is arranged to be inclined gradually from bottom to top toward the feed end of the conveyor belt 113. The sliding direction of the transverse seat 124 is arranged perpendicular to the length direction of the conveyor belt 113. The transverse seat 124 is fixedly connected to a guide slide rod 127 that is horizontally slidably connected to the inclined slide seat 122, which helps to improve the movement accuracy. The two splints 126 are arranged vertically and corresponding to each other. There is a gap between the lower end of each splint 126 and the conveying surface of the conveyor belt 113, and the gap is slightly larger than the height of the partition 115.

[0094] Preferably, each clamping plate 126 is provided with a vertically arranged strip hole, and a connecting bolt screwed to the corresponding transverse seat 124 is inserted into the strip hole, so as to facilitate adjustment of the distance between the clamping plate 126 and the conveying surface of the conveyor belt 113 to adapt to the production of different similar socks.

[0095] The flip-type sock storage mechanism 160 includes a base frame 161 fixedly arranged relative to the conveyor frame 110, two power rollers 162 arranged parallel to each other and rotatably connected to the base frame 161, a flip motor 163 for driving the power rollers 162 to rotate, and a roller 164 directly or indirectly resting on the power rollers 162. The base frame 161 and the conveyor frame 110 can be fixedly connected to the ground or the same frame to achieve a relatively fixed arrangement of the two. In this embodiment, the base frame 161 is directly fixedly connected to the conveyor frame 110. The specific transmission connection structure between the flip motor 163 and the two power rollers 162 can be a conventional structure, such as a gear assembly or a chain assembly. In this embodiment, the two power rollers 162 are respectively connected to the output shaft of the flip motor 163 through a conventional belt assembly to achieve a transmission connection between the flip motor 163 and the two power rollers 162. The central axis of the roller 164 is arranged parallel to both power rollers 162. The two power rollers 162 are located on the same horizontal plane, and the distance between the two power rollers 162 is smaller than the diameter of the roller 164, so that the roller 164 can be supported by the two power rollers 162. In addition, the power rollers 162 are preferably covered with rubber sleeves or rubber wheels, and the roller 164 indirectly rests on the power rollers 162 by abutting against the rubber sleeves or rubber wheels. This helps to increase friction and prevent the power rollers 162 from slipping when driving the roller 164 to rotate. It should be noted that it is also possible to have only one power roller 162 in transmission connection with the flip motor 163, while the other power roller 162 is indirectly driven by the flip motor 163 by being driven by the roller 164. Similarly, the flip motor 163 can directly drive the roller 164 or indirectly drive the roller 164 through a gear assembly, so that both power rollers 162 rotate under the drive of the roller 164 and are indirectly driven by the flip motor 163.

[0096] The drum 164 has an opening on one axial side, which is covered with a cover plate 165 that is directly or indirectly fixed to the base frame 161. The cover plate 165 can prevent the socks inside the drum 164 from flowing out of the opening and will not rotate with the drum 164. The cover plate 165 is provided with a feeding port and a discharging port, which are staggered in the horizontal and vertical directions. A plurality of sock turning plates or sock turning buckets 170 are fixedly connected to the circumferential side walls of the inner cavity of the drum 164 to better lift the socks located in the drum 164. In this embodiment, the sock turning bucket 170 is fixedly connected to the circumferential side walls of the inner cavity of the drum 164 as an example for explanation. The sock turning bucket 170 includes a support plate 171 that is directly or indirectly fixed to the drum 164 through a connecting piece, an oblique support plate 172 that is fixedly connected to one end of the support plate 171 facing the central axis of the drum 164, and two material plates 173 that are respectively fixedly connected to the oblique support plate 172. In the figure, the support plate 171 and the oblique support plate 172 can be fixedly connected in an integral manner, and an angle is formed between the two, which is an obtuse angle. The two material plates 173 are fixedly connected to the support plate 171 at the same time, that is, each material plate 173 is fixedly connected to the support plate 171 and the oblique support plate 172 at the same time, and the distance between the two material plates 173 gradually increases from one end connected to the oblique support plate 172 to the other end, and a sock turning cavity is formed between the two material plates 173, which helps to concentrate the lifted socks on the conveyor belt 113 mentioned below. Preferably, one end of each material plate 173 away from the support plate 171 is fixedly connected to a sock blocking plate 174, and each sock blocking plate 174 is staggered with the corresponding sock turning cavity to prevent socks from being thrown to the side of the material plate 173 away from the corresponding sock turning cavity. Of course, the sock blocking plate 174 can also be used to close or semi-close the space enclosed by the side of the material plate 173 away from the corresponding sock turning cavity and the support plate 171 and the oblique support plate 172 to prevent socks from entering the space.

[0097] During use, socks can be poured directly into the drum 164 from the feeding port. However, if the socks are poured directly into the drum 164 from outside the feeding port, the socks are likely to fall outside the drum 164. If the socks are poured into the drum 164 by extending into the drum 164, the machine needs to be stopped. Otherwise, the socks are likely to be hit by the sock turning plate or the sock turning bucket 170, and the socks in the drum 164 are also likely to be thrown out. In order to avoid the above problems, in this embodiment, the cover plate 165 is fixedly connected to a feeding box at a position corresponding to the feeding port. The feeding box includes a fixed The box body 181 is fixedly connected to the cover plate 165. The box body 181 has a blanking port connected to the feeding port on the side facing the cover plate 165. A feed port is provided on one of the circumferential side walls of the box body 181. Of course, the feed port and the blanking port are located on different side walls. In addition, the bottom of the inner cavity of the box body 181 is gradually tilted upward from the side relatively close to the cover plate 165 to the corresponding other side. In this way, after the socks are fed into the box body 181 from the feed port, they will flow into the drum 164 along the inclined bottom surface through the feed port.

[0098] Preferably, the box body 181 is rotatably connected to the discharge box 182 at a position below the feed port, and the rotation connection shaft between the two is arranged horizontally. One end of the discharge box 182 has a material transfer port. When the discharge box 182 rotates to a position close to the box body 181, the discharge box 182 covers the feed port, and the material transfer port and the feed port are connected to each other. When the discharge box 182 flips downward from the position covering the feed port to the extreme position, the side wall of the discharge box 182 abuts against the side wall of the box body 181, and the material transfer port faces The upper arrangement is provided. In addition, a locking rod 183 is rotatably connected to the box body 181, and a locking groove is opened at one end of the locking rod 183. A lock buckle 184 that cooperates with the locking groove is fixedly connected to the discharge box 182. In this way, the socks can be poured into the discharge box 182 first, and then the socks can be poured into the box body 181 by turning the discharge box 182 over. It is more convenient to use, and when there is no need to feed, the discharge box 182 can be locked to the box body 181 by the locking rod 183 to close the feed port to avoid other items being accidentally put into the drum 164.

[0099] One end of the conveyor belt 113 passes through the inner cavity of the drum 164 from the discharge port, and this end is the feed end of the conveyor belt 113. When in use, the socks in the drum 164 are lifted from the bottom of the drum 164 and thrown to the feed end of the conveyor belt 113 under the action of the sock turning plate or the sock turning bucket 170. At this time, the conveyor belt 113 does not move, and the socks are arranged in a pile at the feed end of the conveyor belt 113. In order to ensure that the socks can be accurately thrown to the feed end of the conveyor belt 113, if necessary, a guide mechanism (such as a conventional guide plate or a guide hopper, etc.) fixedly connected to the conveyor frame 110 or the cover plate 165 can also be provided at the feed end of the conveyor belt 113.

[0100] During use, when the pile of socks is transported to the position corresponding to the scattering assembly 120, the conveyor belt 113 stops moving, and the two transverse cylinders 125 respectively drive the two clamping plates 126 to move toward each other to clamp the socks on the upper part of the sock pile. Then the inclined sliding cylinder 123 drives the inclined sliding seat 122 to slide upward along the inclined sliding rod 121 to transport the clamped socks toward the feeding end, and then the transverse cylinder 125 is used to drive the two clamping plates 126 to move away from each other, so that the socks fall onto the conveyor belt 113 under the action of gravity. After that, the scattering assembly 120 is reset, and the conveyor belt 113 continues to move to transport the next sock pile to the position corresponding to the scattering assembly 120, and the above actions are repeated.

[0101] Preferably, a plurality of equally spaced partitions 115 are fixedly connected to the outer circumference of the conveyor belt 113. This facilitates stacking of socks and allows the partitions 115 to push the material in the return channel described below. The partitions 115 are preferably made of hard rubber with a certain degree of elastic deformation.

[0102] A front baffle 130 and a rear baffle 140 are also provided above the conveying surface of the conveyor belt 113, which are directly or indirectly fixedly connected to the conveyor frame 110. In this embodiment, the front baffle 130 and the rear baffle 140 are respectively fixedly connected to the conveyor frame 110 through brackets, and the connection structure between the front baffle 130 and the rear baffle 140 and the corresponding bracket brackets is the same as the connection structure between the splint 126 and the transverse displacement seat 124, that is, the height position of the front baffle 130 and the rear baffle 140 can also be adjusted.

[0103] The front baffle 130 is a metal plate located on the side of the scattering assembly 120 facing the feed end of the conveyor belt 113. The front baffle 130 is arranged to tilt gradually from bottom to top toward the discharge end of the conveyor belt 113. This helps pre-flatten relatively high piles of socks, preventing the scattering assembly 120 from having to flatten too many socks, which would affect the smoothing effect of the socks. Because the presence of the front baffle 130 could push socks off the conveyor belt 113, a component for receiving socks, such as a material frame, is preferably provided below the feed end of the conveyor belt 113.

[0104] The rear baffle 140 is a flexible plate with a certain degree of elastic deformation. It is located on the side of the deflating assembly 120 facing the discharge end of the conveyor belt 113. It is used to prevent unflattened socks from being directly conveyed to the discharge end of the conveyor belt 113. The lower portion of the rear baffle 140 also has a wavy structure, which can organize the socks and arrange them roughly along the length of the conveyor belt 113, facilitating subsequent processing.

[0105] A recognition camera is provided above the discharge end of the conveyor belt 113, and a sock clamping robot 190 (see FIG. 1 ) is provided next to the discharge end of the conveyor belt 113 for clamping and moving socks from the conveyor belt 113 to the sock clamping conveying mechanism 250 to be mentioned below. Figure 1 In this embodiment, the sock gripper 190 is a commercially available multi-joint parallel robot positioned above the discharge end of the conveyor belt 113. A recognition camera is used to identify the socks and their openings lying flat on the discharge end of the conveyor belt 113. The sock gripper 190 then removes the socks and places them on the opening leveling device 200, thereby achieving automatic feeding of the sock production line.

[0106] Taking into account that some socks may still be stacked on each other after being flattened by the scattering component 120, and the socks stacked below will not be taken away by the sock clamping robot 190, therefore, in this embodiment, a bottom plate 150 located below the circulation section of the conveyor belt 113 is fixedly connected to the conveyor frame 110, and a return channel is formed between the bottom plate 150 and the conveyor belt 113, and the end of the bottom plate 150 corresponding to the discharge end of the conveyor belt 113 is located on the side of the discharge end of the conveyor belt 113 away from the scattering component 120, so as to receive the socks that fall from the discharge end of the conveyor belt 113, and the other end of the bottom plate 150 passes through the cover plate 165 and extends into the drum 164, so that the socks flowing out of the return channel can flow back into the drum 164. Furthermore, a pusher cylinder 151 is connected to the base plate 150, located at the discharge end of the conveyor belt 113, away from the scattering assembly 120. The piston rod of the pusher cylinder 151 is horizontally oriented toward the return channel, and a pusher plate 152 is fixedly connected to the piston rod of the pusher cylinder 151. During operation, socks that have not been removed from the discharge end of the conveyor belt 113 will fall to the base plate 150 under the action of gravity. These socks are then pushed into the return channel by the pusher cylinder 151, causing them to flow back under the feed end of the conveyor belt 113 and fall into the drum 164 under the action of gravity.

[0107] like Figure 6-Figure 8As shown, the sock opening flattening device 200 includes a flattening frame 210, on which a horizontally arranged belt conveyor mechanism 220 and a flattening plate 230 and a sock pressing mechanism 240 are arranged in sequence along the conveying direction of the belt conveyor mechanism 220. The belt conveyor mechanism 220 is a conventional mechanism that can be purchased on the market. It includes an active roller, a driven roller, a conveying belt 221 wound between the active roller and the driven roller, and a belt conveying motor 222 for driving the active roller to rotate. The conveying belt 221 forms a conveying section and a circulating section below the conveying section between the active roller and the driven roller (the conveying section and the circulating section are not fixed belt sections on the conveying belt 221. As the conveying belt 221 rotates, the conveying section and the circulating section will continuously change corresponding to the belt section on the conveying belt 221). A support platform or support roller for supporting the conveying section is provided between the conveying section and the circulating section, and the upper side surface of the conveying section forms a conveying surface.

[0108] The feeding end of the belt conveyor mechanism 220 is connected to the sock conveyor mechanism 250. The sock conveyor mechanism 250 can be a conventional conveying mechanism, such as a belt conveyor mechanism with the same structure as the belt conveyor mechanism 220 or a conventional chain plate conveyor mechanism, etc., which will not be described in detail here. An air blowing nozzle 251 is provided on one side of the sock conveyor mechanism 250, and a detection camera is provided just above the conveying surface of the sock conveyor mechanism 250. Of course, the position of the detection camera corresponds to the position of the air blowing nozzle 251. In addition, a collecting channel 253 (see FIG. 2 ) that is connected or connected to the return channel is provided on the side of the sock conveyor mechanism 250 away from the air blowing nozzle 251. Figure 1 As shown, the collection channel 253 can be an inclined trough or discharge plate. In this way, after the sock gripper robot 190 lays the socks flat on the conveying surface of the sock gripper conveyor mechanism 250, when the socks are conveyed to the position corresponding to the inspection camera, the socks are photographed and inspected by the inspection camera. If the socks are found to have defects or the placement does not meet the process requirements, the air nozzle 251 blows the socks away from the conveying surface of the sock gripper conveyor mechanism 250, allowing the socks to flow back into the drum 164 through the collection channel 253 and the return channel. Otherwise, the socks are fed from the output end of the sock gripper conveyor mechanism 250 to the feed end of the belt conveyor mechanism 220. In addition, a receiving plate 252 is preferably provided between the belt conveyor mechanism 220 and the sock gripper conveyor mechanism 250 to prevent socks from falling during transportation between the two conveyor mechanisms. It should be noted that in the process of using the sock clamping robot 190 to spread the socks flat on the sock clamping conveying mechanism 250, the sock clamping robot 190 should move the socks a certain distance along the conveying direction of the sock clamping conveying mechanism 250 to ensure that the sock openings of the socks placed on the sock clamping conveying mechanism 250 are facing the discharge end of the sock clamping conveying mechanism 250.

[0109] The leveling plate 230 is arranged parallel to the conveying direction of the belt conveyor 220 and is located above the conveying surface of the belt conveyor 220. Specifically, an adjustment frame 231 is fixedly connected to the leveling plate 230. The adjustment frame 231 has at least two waist-shaped holes 232 arranged parallel to the support rods 241 described below. The length of the waist-shaped holes 232 is perpendicular to the conveying direction of the belt conveyor 220. Adjustment bolts (not shown) fixed to the leveling frame 210 are inserted through the waist-shaped holes 232. This ensures a fixed connection between the leveling plate 230 and the leveling frame 210 and facilitates adjustment of the position of the leveling plate 230 to accommodate the production of socks of different specifications. The distance between the leveling plate 230 and the conveying surface of the belt conveyor 220 is less than the thickness of the socks to be leveled to prevent socks from being inserted under the leveling plate 230. Preferably, one end of the leveling plate 230 facing the input end of the belt conveyor mechanism 220 is connected to a guide plate 233 to guide the socks on the conveying surface to the same side of the leveling plate 230 for easy manual alignment.

[0110] The sock pressing mechanism 240 includes a support rod 241 located above the conveying surface of the belt conveyor mechanism 220 and arranged perpendicular to the conveying direction of the belt conveyor mechanism 220, a sock pressing cylinder 242 fixedly connected to the support rod 241 and with the piston rod arranged vertically downward, a leveling cylinder 243 fixedly connected to the lower end of the piston rod of the sock pressing cylinder 242 and with the piston rod horizontally facing the output end of the belt conveyor mechanism 220, a movable block 244 fixedly connected to the piston rod of the leveling cylinder 243, a leveling rod 245 fixedly connected to the lower end of the movable block 244 and arranged horizontally, a sock pressing frame 246 fixedly connected to the lower end of the cylinder body of the leveling cylinder 243, and a sock pressing roller 247 rotatably connected to the sock pressing frame 246, wherein the support rod 241 is arranged horizontally, and its two ends are fixedly connected to the leveling frame 210 by vertical rods.

[0111] There are at least two pressing rollers 247, each located on the same horizontal plane and arranged sequentially along the conveying direction of the belt conveyor 220. The pressing rollers 247 are arranged parallel to the support rods 241. The spacing between the pressing rollers 247 and the conveying surface of the belt conveyor 220 is always smaller than the spacing between the leveling rods 245 and the conveying surface of the belt conveyor 220, ensuring that the leveling rods 245 can still operate when the pressing rollers 247 compress the socks. Furthermore, the pressing rollers 247 are preferably rubber rollers or rollers covered with rubber sleeves. This not only helps increase friction between the pressing rollers 247 and the socks but also prevents socks from being crushed. The leveling rods 245 are metal rods.

[0112] Preferably, a horizontally arranged connecting plate 248 is fixedly connected to the piston rod of the sock pressing cylinder 242, and the cylinder body of the leveling cylinder 243 is indirectly connected to the piston rod of the sock pressing cylinder 242 by being fixedly connected to the connecting plate 248, and a guide rod 249 is also fixedly connected to the connecting plate 248 and vertically slidably connected to the support rod 241, which helps to improve the stability of the downward pressing action.

[0113] During operation, the socks are sequentially placed flat on the sock-gripping conveyor mechanism 250 by the sock-gripping robot 190. Unqualified socks are removed using the air nozzle 251, and the remaining socks are then conveyed to the belt conveyor mechanism 220. The socks are manually pressed against the leveling plate 230 and leveled on the belt conveyor mechanism 220, with the sock openings facing the output end of the belt conveyor mechanism 220. Driven by the belt conveyor mechanism 220, the leveled socks are moved directly below the sock-pressing rollers 247. The sock-pressing cylinder 242 then drives the sock-pressing rollers 247 to press the socks against the conveying surface of the belt conveyor mechanism 220. The socks then roll on the conveyor mechanism 220 as they move. Simultaneously, the leveling cylinder 243 drives the leveling rod 245 toward the output end of the belt conveyor mechanism 220, leveling the sock openings. After completing these steps, the cylinders reset.

[0114] The socks placing and folding device 300 can be a conventional device, for example, a plurality of conventional manipulators can imitate manual folding. Figures 9-12 As shown, the sock placing and folding device 300 provided in this embodiment includes a supporting frame 310, on which a material receiving and conveying mechanism 320, a sock swinging mechanism 330 and a sock folding station arranged in a straight line are provided. The sock folding station can be a manual station. In this embodiment, the sock folding station is provided with a sock folding mechanism 340 and a material discharging conveying mechanism 350.

[0115] The material receiving conveying mechanism 320 is a conventional belt conveying mechanism, which can be purchased directly from the market and will not be described in detail here.

[0116] The sock-swinging mechanism 330 includes a worktable 331 horizontally slidably connected to the support frame 310, a transverse cylinder 332 for driving the worktable 331 to slide, a movable bracket 333 slidably connected below or to the side of the worktable 331, a longitudinal cylinder 334 for driving the movable bracket 333 to slide, a pressing plate 335 located above the worktable 331, a lifting cylinder 336 for driving the pressing plate 335 up and down, and a sock-clamping mechanism 360 located above the pressing plate 335. The pressing plate 335 is preferably a transparent plate so that the flatness of the socks held by the pressing plate 335 can be directly observed. The conveying surface of the material receiving and conveying mechanism 320 is located at a higher level than that of the worktable 331. This height difference allows the ends of the socks to droop under the action of gravity as they are clamped from the material receiving and conveying mechanism 320 to the worktable 331, thus providing a certain degree of sock straightening and ensuring that the socks are flat and not twisted.

[0117] The cylinder body of the transverse cylinder 332 is fixedly connected to the support frame 310, and the lower side of the work table 331 is fixedly connected to a transition frame 337 that is horizontally slidably connected to the support frame 310. The transition frame 337 is fixedly connected to the piston rod of the transverse cylinder 332, thereby realizing the connection between the transverse cylinder 332 and the work table 331; the piston rod of the transverse cylinder 332 is horizontally arranged and perpendicular to the length direction of the work table 331 to ensure that the sliding direction of the work table 331 is perpendicular to the length direction of the work table 331.

[0118] A sliding rod is fixedly connected to the transition frame 337, and the mobile bracket 333 is slidably connected to the sliding rod to achieve a sliding connection with the worktable. The cylinder body of the longitudinal movement cylinder 334 is fixedly connected to the mobile bracket 333, and the piston rod of the longitudinal movement cylinder 334 is fixedly connected to the mobile bracket 333, thereby achieving a connection between the longitudinal movement cylinder 334 and the mobile bracket 333. The piston rod of the longitudinal movement cylinder 334 is arranged parallel to the length of the worktable 331 to ensure that the sliding direction of the mobile bracket 333 is parallel to the length of the worktable 331.

[0119] The cylinder body of the lifting cylinder 336 is fixedly connected to the movable bracket 333 (that is, the lifting cylinder 336 is installed on the movable bracket 333), and the piston rod of the lifting cylinder 336 is arranged vertically upward and fixedly connected to the pressure plate 335, thereby realizing the connection between the pressure plate 335 and the lifting cylinder 336.

[0120] The sock clamping mechanism 360 can be a conventional multi-joint manipulator. In this embodiment, the sock clamping mechanism 360 includes a sock clamping bracket 361 horizontally slidably connected to the support frame 310, a sock clamping motor 362 for driving the sock clamping bracket 361 to move, a lifting frame 363 vertically slidably connected to the sock clamping bracket 361, a lifting cylinder 364 for driving the lifting frame 363 to slide, a retreat cylinder 365 installed on the lifting frame 363, a connecting plate 366 fixedly connected to the piston rod of the retreat cylinder 365, and a lower telescopic cylinder 367 fixedly connected to the cylinder body and the connecting plate 366. The upper telescopic cylinder 368, whose cylinder body is fixedly connected to the lifting frame 363, the lower clamping plate 369, which is fixedly connected to the piston rod of the lower telescopic cylinder 367, and the upper clamping plate 370, which is fixedly connected to the piston rod of the upper telescopic cylinder 368, wherein the sliding direction of the sock clamping bracket 361 is parallel to the length of the worktable 331. The specific transmission connection structure between the sock clamping motor 362 and the sock clamping bracket 361 can be a conventional structure, such as a conventional chain assembly or gear rack assembly. In this embodiment, the two are connected by a conventional transmission belt assembly. The cylinder body of the lifting cylinder 364 is fixedly connected to the sock clamping bracket 361, and the piston rod of the lifting cylinder 364 is arranged vertically downward and fixedly connected to the lifting frame 363. In addition, to ensure the movement accuracy of the lifting frame 363, a guide rod is fixedly connected to the lifting frame 363 and vertically slidably connected to the sock clamping bracket 361.

[0121] The cylinder body of the retreat cylinder 365 is fixedly connected to the lifting frame 363. The piston rod of the retreat cylinder 365 is parallel to the length of the work table 331 and faces the side away from the material receiving and conveying mechanism 320. The lower telescopic cylinder 367 is located directly below the retreat cylinder 365, and the piston rods of the lower telescopic cylinder 367 and the upper telescopic cylinder 368 are both arranged vertically downward. The upper clamping plate 370 is located directly above the lower clamping plate 369. Preferably, a limit block 371 is fixedly connected or integrally connected to the upper clamping plate 370.

[0122] The sock folding mechanism 340 includes a horizontally arranged receiving plate 341, a receiving cylinder 342 for driving the receiving plate 341 to move up and down, a sock pressing frame 343 located just above the receiving plate 341, a sock pressing cylinder 344 for driving the sock pressing frame 343 to move up and down, a sock pressing roller 345 rotatably connected to the sock pressing frame 343, a vertically arranged bending plate 346, a bending cylinder 347 for driving the bending plate 346 to move up and down, a clamping assembly 380 horizontally slidably connected to the support frame 310, and a folding motor 351 for driving the clamping assembly 380 to slide, wherein the receiving plate 341 is located on the side of the work table 331 away from the material receiving and conveying mechanism 320, and the horizontal position of the receiving plate 341 when it moves to the lower limit position is lower than the horizontal position of the work table 331, The connecting plate 341 is fixedly connected to a guide rod arranged vertically on the support frame 310 to ensure the movement accuracy. The cylinder body of the receiving cylinder 342 is fixedly connected to the support frame 310, and its piston rod is arranged vertically upward and fixedly connected to the connecting plate 341; the sock pressing frame 343 is also fixedly connected to a guide rod arranged vertically on the support frame 310, and the cylinder body of the sock pressing cylinder 344 is fixedly connected to the support frame 310, and its piston rod is arranged vertically downward and fixedly connected to the sock pressing frame 343; the upper end of the bending plate 346 is fixedly connected to a cross bar, and the two ends of the cross bar are respectively fixedly connected to guide rods vertically slidably connected to the support frame 310, and the cylinder body of the bending cylinder 347 is fixedly connected to the support frame 310, and its piston rod is arranged vertically upward and fixedly connected to the cross bar. In addition, the bending plate 346 is located on the side of the receiving plate 341 away from the workbench 331. The projections of the bending plate 346 and the receiving plate 341 on the horizontal plane are staggered with each other, and the distance between the two is slightly greater than 1-5 times the thickness of a pair of socks.

[0123] Preferably, a strip 348 arranged parallel to the stocking pressing roller 345 and / or a positioning plate 349 arranged perpendicular to the stocking pressing roller 345 are fixedly connected to the receiving plate 341. In this embodiment, the receiving plate 341 is provided with both the strip 348 and the positioning plate 349. The projections of the strip 348 and the stocking pressing roller 345 on the horizontal plane are offset from each other. When the stocking pressing roller 345 presses the socks against the receiving plate 341, the presence of the strip 348 causes the socks to bend, increasing the resistance to their movement relative to the receiving plate 341 and ensuring the accuracy of the folding position. Two positioning plates 349 are arranged parallel to each other and are both located on the side of the strip 348 facing the workbench 331. They are used to ensure that the socks are positioned within the range corresponding to the length of the stocking pressing roller 345.

[0124] The specific transmission connection structure between the folding motor 351 and the clamping assembly 380 can be a conventional structure, such as a belt assembly, a rack and pinion assembly, or a chain assembly, and will not be described in detail here. The sliding direction of the clamping assembly 380 is parallel to the length of the work table 331. The sock pressing roller 345 is arranged parallel to the receiving plate 341 and perpendicular to the sliding direction of the clamping assembly 380.

[0125] The clamping assembly 380 includes a sliding frame 381 slidably connected to the support frame 310 and a finger cylinder 382 installed on the sliding frame 381, wherein the two finger rods of the finger cylinder 382 are respectively fixedly connected with a clamping plate 383, and the two clamping plates 383 are arranged up and down.

[0126] The discharge conveyor mechanism 350 is a conventional commercially available belt conveyor and will not be described in detail here. The discharge conveyor mechanism 350's conveying direction is parallel to the length of the worktable 331. When the clamping assembly 380 moves to its limit position away from the receiving plate 341, the clamping assembly 380 is directly above the conveying surface of the discharge conveyor mechanism 350. When the clamping assembly 380 moves to its limit position toward the worktable 331, the receiving plate is inserted between the two clamping plates 383.

[0127] Preferably, a position adjustment mechanism 390 is provided on one side of the discharging conveying mechanism 350. The position adjustment mechanism 390 includes an adjusting cylinder 391 fixedly connected to the supporting frame 310 and a vertical plate 392 fixedly connected to the piston rod of the adjusting cylinder 391. The piston rod of the adjusting cylinder 391 is arranged parallel to the width direction of the discharging conveying mechanism 350, and the vertical plate 392 is arranged perpendicular to the piston rod of the adjusting cylinder 391. In this way, the telescopic action of the adjusting cylinder 391 can be used to push the vertical plate 392 to move, thereby pushing the position of the socks located on the discharging conveying mechanism 350 on the conveying surface, thereby realizing the adjustment of the sock conveying position and facilitating subsequent packaging.

[0128] When in use, the flattened socks are conveyed to the material receiving and conveying mechanism 320, and the sock openings of the socks are facing the sock swinging mechanism 330. When the socks are conveyed to the end of the conveying surface of the material receiving and conveying mechanism 320 by the material receiving and conveying mechanism 320, the sock openings of the socks are clamped by the sock clamping mechanism 360 (achieved by the lower telescopic cylinder 367 and the upper telescopic cylinder 368 driving the upper clamping plate 370 and the lower clamping plate 369 to move). Then the sock clamping motor 362 drives the sock clamping bracket 361 to move away from the material receiving and conveying mechanism 320, and at the same time, the lifting cylinder 364 drives the lifting frame 363 to move downward, placing the sock clamp on the end of the workbench 331 away from the material receiving and conveying mechanism 320, and then the lower telescopic cylinder 367 and the upper telescopic cylinder 368 drives the upper clamping plate 370 and the lower clamping plate 369 to loosen, and at the same time, the piston rod of the retreat cylinder 365 extends, driving the lower clamping plate 369 to move away from directly under the sock to avoid the sock being hit during the resetting process of the sock clamping mechanism 360; during the resetting process of the sock clamping mechanism 360, the transverse cylinder 332 drives the workbench 331 to move along its width direction, and then uses the sock clamping mechanism 360 to clamp another sock and place it on the workbench 331, parallel to the sock placed earlier. It should be noted that the number of socks placed side by side on the workbench 331 can be determined according to actual needs. You only need to repeat the above actions. Here, we take the example of placing two socks side by side on the workbench 331 at the same time.After completing the above actions, the longitudinal movement cylinder 334 drives the pressing plate 335 to move to the top of the socks arranged side by side on the workbench 331, and then the lifting cylinder 336 is used to drive the pressing plate 335 to move down and press on the sock body of each sock (that is, the sock opening position is not pressed). Then, the sock clamping mechanism 360 clamps the socks again and stacks them on top of the socks on the workbench 331. The specific actions are the same as those described above and will not be described in detail here. After stacking, the pressing plate will be clamped between the two stacked socks to complete the sock swinging. Then, the clamping assembly 380 is used to clamp the socks placed on the work table 331 at the same time, and then the pressing plate 335 is reset. The clamping assembly 380 clamps the socks and places them on the receiving plate 341 and the conveying surface of the discharge conveying mechanism 350. That is to say, at this time, one end of the socks is located on the work table 331, and the other end is located on the conveying surface of the discharge conveying mechanism 350. Of course, when the socks are short, they can also be placed only on the work table 331, and then the receiving cylinder 342 drives the receiving plate 341 to move up, and the sock pressing air cylinder 342 presses the socks at the same time. The cylinder 344 drives the sock pressing roller 345 to move downward and press the sock against the receiving plate 341, which helps to shorten the movement stroke and improve efficiency; then, the bending cylinder 347 drives the bending plate 346 to move downward, pushing one end of the pressed sock (i.e., the part placed on the conveying surface of the discharge conveying mechanism 350) downward, so that the sock is bent at a right angle; after the bending action is completed, the bending plate 346 is reset, and the bent part of the sock is clamped by the clamping assembly 380, and then the sock pressing roller 345 is reset, and the clamping assembly 380 drives the sock away from the receiving plate 341 is moved and released, so that the socks are dragged to the conveying surface of the discharge conveying mechanism 350, and the socks are in a folded state at this time; finally, the socks are conveyed to the next workstation (usually a conventional workstation such as a packaging workstation, which is not part of this embodiment and needs to be configured separately when in use, and will not be described in detail here) via the discharge conveying mechanism 350 to complete the placement and folding action. During the conveyance of the socks on the discharge conveying mechanism 350, the position adjustment mechanism 390 can be used to adjust the conveying position of the socks so as to better cooperate with the next workstation.

[0129] The present invention has been described in detail above with reference to the accompanying drawings. However, the embodiments of the present invention are not limited to the above embodiments. Those skilled in the art can make various changes and applications to the present invention based on the existing technology. For example, the cylinder in the above embodiment can be replaced by a hydraulic cylinder or a push rod motor, etc. These all fall within the scope of protection of the present invention.
