Description

Technical Field

[0001] This invention relates to the field of sock knitting technology, and more specifically, to a fully automatic sock inspection and sorting machine and its usage method. Background Technology

[0002] A sock knitting machine is a textile device used to knit socks. It includes a frame, a knitting tray on the frame, knitting needles on the knitting tray, and a yarn guide tray outside the knitting tray. The yarn guide tray has sliding yarn guide nozzles. During the knitting process, the yarn guide nozzles transfer the yarn located on the yarn tray to the knitting needles, where it works in conjunction with the needles to knit and produce socks.

[0003] Currently, during the production of socks, the quality of socks is inspected manually by stretching the sock openings. This manual inspection is not only time-consuming and labor-intensive, but the degree of stretching is also inconsistent, leading to significant errors and low inspection efficiency. In addition, the socks after inspection also need to be stacked manually, which is even more time-consuming and labor-intensive. Summary of the Invention

[0004] In view of this, the present invention aims to propose a fully automatic sock inspection and sorting machine and its usage method. This addresses the problem in the existing technology where, during sock production, the quality of socks is inspected manually by stretching the sock openings. Manual inspection is not only time-consuming and labor-intensive, but also prone to inconsistencies in the degree of stretching, leading to significant errors and low inspection efficiency. Furthermore, the stacking of inspected socks requires manual stacking, further increasing the time and labor costs.

[0005] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0006] A fully automatic sock sorting machine includes at least:

[0007] Support frame:

[0008] Sock stretching assembly: The sock stretching assembly is fixed to the support frame by a sock stretching fastener. The sock stretching assembly includes a sock stretching tube, a sock stretching cylinder, a vertical moving part, and a horizontal moving part. The sock stretching tube surrounds the outer periphery of the sock stretching cylinder. The sock stretching cylinder has a notch. The horizontal moving part passes through the notch and connects to the sock stretching tube. The horizontal moving part and the vertical moving part cooperate to stretch the sock on the sock stretching tube.

[0009] Pick-up component: The pick-up component is mounted on the support frame. The pick-up component includes a straightening part and a placement part. The straightening part is used to straighten the socks on the sock support tube, and the placement part is used to remove the socks from the sock support tube and place them in a suitable position.

[0010] This setup replaces manual stretching of socks with a sock stretching component, greatly reducing manual labor and improving work efficiency. The straightening part of the pick-up component can make the socks flatter on the stretching tube, making it easier to inspect the socks during stretching.

[0011] Furthermore, it also includes a stacking assembly, which includes a tray, a second movable frame, and a sock placement plate. The tray and the sock placement plate have a certain height. The tray is mounted on the second movable frame, which is movable relative to the support frame and moves the tray accordingly. The second movable frame is fixed to the support frame, and the sock placement plate is fixed to the support frame.

[0012] Furthermore, the second movable frame includes a second X-axis support and a second Y-axis support, the second X-axis support and the second Y-axis support are slidably connected, the second X-axis support is fixed on the support frame, and the second Y-axis support is connected to the tray.

[0013] This setup allows the tray to move up and down and left and right, coordinating with the movement of the placement unit. This enables both flat placement of socks and multi-layer stacking of socks, avoiding time-consuming and laborious manual labor and significantly improving work efficiency.

[0014] Furthermore, the lateral moving component includes a first inclined plane moving block and a second inclined plane moving block, wherein the first inclined plane moving block moves relative to the vertical moving component, and the second inclined plane moving block moves relative to the vertical moving component.

[0015] This setting allows the socks to be stretched out on the sock stretcher.

[0016] Furthermore, the stocking tube is provided with a first notch and a second notch, the first inclined moving block passes through the first notch and connects to the stocking tube, and the second inclined moving block passes through the second notch and connects to the stocking tube.

[0017] Furthermore, one end of the first inclined moving block contacts the vertical moving member, and the other end of the first inclined moving block passes through the first notch and connects to the stocking tube. The second inclined moving block contacts the vertical moving member, and the other end of the second inclined moving block passes through the second notch and connects to the stocking tube.

[0018] Furthermore, the vertical moving component includes a pull rod, a first trapezoidal cylinder, and a second trapezoidal cylinder. The pull rod passes through the first trapezoidal cylinder, and the first trapezoidal cylinder moves on the pull rod to cause the first inclined plane moving block to move laterally. The second trapezoidal cylinder is movably connected to the pull rod, and the pull rod pulls the second trapezoidal cylinder to cause the second inclined plane moving block to move laterally.

[0019] Furthermore, the straightening part includes at least a first gripper, and the placement part includes at least a second gripper, with the first gripper and the second gripper connected to a first connecting plate.

[0020] In this setup, the first gripper is used to straighten the socks on the stocking tube, and the second gripper is used to remove the socks from the stocking tube so that the socks can be placed flat on the sock placement board, replacing the time-consuming and laborious manual work and improving work efficiency.

[0021] Furthermore, the stocking support assembly is fixed to the stocking support fixture by bearings, and the stocking support assembly is rotatable relative to the stocking support fixture.

[0022] This setting allows for comprehensive inspection of the socks on the stocking tubes, improving work efficiency.

[0023] The above-described method of using a fully automatic sock inspection and sorting machine includes the following steps:

[0024] Step 1: Move the stocking stretcher to the exit of the sock knitting machine, and the swinging part of the sock knitting machine will put the sock onto the stocking stretcher;

[0025] Step 2: Move the first grab to directly above the stocking stretcher. At this time, the second grab is open and the first grab is closed. Move the first grab downward to straighten the stocking on the stretcher, and then release the first grab.

[0026] Step 3: Activate the stocking stretcher assembly to stretch the stockings on the stretcher tubes. At the same time, the stretcher tubes rotate at a certain speed to test the stockings. If the stockings fail the test, proceed to Step 4. If the stockings pass the test, proceed to Step 5.

[0027] Step 4: Move the stocking stretcher closer to the second grabber, the second grabber closes to clamp the stocking, and move the second grabber to place the stocking in the defective area;

[0028] Step 5: Move the tray so that it is at a certain height relative to the sock rack, and this height is sufficient to stack N layers of socks. Then move the sock support tube closer to the second gripper. The second gripper closes to clamp the socks. Move the second gripper to move the socks closer to the tray, and the vertical projection of the socks is closer to the right end of the tray.

[0029] Step Six: While moving the second grab downwards, move the tray to the right simultaneously, controlling the movement speed of the second grab and the tray. When the socks separate from the tray, open the second grab. At this point, the socks are placed flat on the sock placement board, and one layer of socks has been placed on it.

[0030] Step 7: Repeat steps 1-6, stacking N layers of socks on the sock-placing board. Then, the conveyor mechanism on the board will send the N layers of socks to the next process for packaging and sorting.

[0031] This setup enables automatic detection of socks and the stacking of the detected socks, avoiding the time-consuming and labor-intensive manual detection and stacking processes, and greatly improving work efficiency.

[0032] Compared with existing technologies, the present invention provides a fully automatic sock inspection and sorting machine and its usage method.

[0033] It has the following advantages:

[0034] 1) The sock stretching component of the present invention replaces manual stretching of socks, greatly reducing the use of manpower and improving work efficiency. The straightening part of the picking component can make the socks flatter on the stretching tube, and facilitates the inspection of socks during stretching.

[0035] 2) The sock support tube of the present invention is provided with a first notch and a second notch, which can limit the lateral moving part and at the same time make the lateral moving part only move laterally, so that the sock is stretched open by the sock support tube.

[0036] 3) By setting up a pickup component, the present invention can not only make the socks on the knitting tube more uniform and easier to detect, but also make the socks more flatly placed on the stacking component;

[0037] 4) By setting up a stacking component, the present invention not only keeps the socks flat, but also enables multi-layer stacking, reducing manual labor and greatly improving detection efficiency.

[0038] 5) By setting a bearing between the sock support assembly and the fixed assembly, the sock support assembly can rotate within the fixed assembly, enabling rapid all-around inspection of the socks and improving work efficiency. Attached Figure Description

Detailed Implementation

[0053] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Furthermore, a brief explanation of the orientations involved in the following specific embodiments is provided: the directions or positional relationships indicated by "front," "back," "up," "down," "left," "right," "top," and "bottom" mentioned in the embodiments refer to the orientations or positional relationships shown in the accompanying drawings.

[0054] like Figure 1-12 As shown, this invention relates to a fully automatic sock inspection and sorting machine, comprising at least a sock-stretching assembly 1, a sock-stretching fixing member 2, a picking assembly 3, a stacking assembly 4, and a support frame 5. The sock-stretching assembly 1 is used to stretch the socks and is movable relative to the support frame. The sock-stretching assembly is also rotatable relative to the sock-stretching fixing member. This configuration facilitates omnidirectional inspection of the socks. The sock-stretching assembly 1 is fixed to the support frame 5 by the sock-stretching fixing member 2. The picking assembly 3 can not only put the socks on the sock-stretching assembly, but also remove the socks from the sock-stretching assembly and place them on the stacking assembly 4. Both the picking assembly 3 and the stacking assembly 4 are mounted on the support frame 5. The picking assembly and the stacking assembly work together to achieve the stacking of multiple layers of socks.

[0055] Specifically, the stocking support assembly 1 is fixed to the stocking support fixing member 2 by a bearing 24, and the stocking support assembly 1 is rotatable relative to the stocking support fixing member 2.

[0056] In this setup, the sock stretching component replaces manual stretching of socks. At the same time, the cooperation between the picking component and the stacking component enables multi-layer stacking of socks, greatly reducing manual labor and improving efficiency. Meanwhile, the sock stretching fixing component is connected to the sock stretching component through the bearing, which allows the sock stretching component to rotate on the sock stretching fixing component, enabling all-round inspection of the socks.

[0057] Specifically, the fully automatic sock inspection and sorting machine also includes a detection component (not shown in the figure). The detection component includes a high-definition camera and a slide rail. The high-definition camera reads pre-stored parameters for detection. The movement of the slide rail enables the high-definition camera to inspect the socks on the sock support assembly. The specific steps are as follows: when a sock needs to be inspected, the detection component moves close to the sock support assembly, first adjusts the height of the sock support assembly, and then rotates the sock support assembly. The detection component can perform all-round inspection of the socks.

[0059] Specifically, the lateral moving member 14 includes a first inclined moving block 141 and a second inclined moving block 142. Preferably, the first inclined moving block 141 is located at the lower end of the second inclined moving block 142. The stocking tube 12 is provided with a first notch 1211 and a second notch 1212.

The second inclined plane moving block passes through the second notch, and the lower end of the second notch limits the lower end of the second inclined plane moving block, so that the second moving block can only move laterally.

[0061] Specifically, one end of the first inclined moving block 141 contacts the vertical moving member 13, and the other end of the first inclined moving block 141 passes through the first notch 1211 and connects to the stocking tube.

[0080] More specifically, the movement of the first fixing part 21 causes the sock support assembly 1 to move up and down, thereby adjusting the position of the socks to facilitate sock detection.

[0081] More specifically, the groove includes a first side 231, a second side 232, and a third side 233 connected in sequence. The first side 231 and the second side 232 are located on the front and rear sides of the groove, and the first side 231 is connected to the fourth support plate 214.

[0096] A method of using a fully automatic sock inspection and sorting machine, employing the aforementioned fully automatic sock inspection and sorting machine, includes the following steps:

[0097] Step 1: Move the stocking stretcher to the exit of the sock knitting machine, and the swinging part of the sock knitting machine will put the sock onto the stocking stretcher;

[0098] Step 2: Move the first gripper to directly above the stocking tube. At this time, the two semi-circular arc structures of the first gripper are in a closed state, and the second gripper is in an open state. Move the first gripper downward to straighten the stocking on the stocking tube, and then release the first gripper. At this time, the two semi-circular arc structures are in a released state. This setting allows the stocking tube to move relative to the support frame.

[0099] Step 3: Activate the stocking stretching assembly to stretch the stockings on the stretching tubes while the stretching tubes rotate at a certain speed. Activate the detection assembly to test the stockings. If the stockings fail the test, proceed to Step 4; if the stockings pass the test, proceed to Step 5.

[0100] Step 4: Move the stocking stretcher closer to the second grabber so that the second grabber can hold the stocking, and move the second grabber to place the stocking in the defective area.

[0101] Step 5: Move the tray up and down to a certain height between the tray and the sock rack, a height sufficient to stack N layers of socks. Then move the sock support tube closer to the second gripper, so that the second gripper clamps the socks. Move the second gripper to move the socks closer to the tray, with the vertical projection of the socks close to the right end of the tray. The distance between this point and the left end of the tray is the length of the sock. This setting ensures that when the tray is moved to the length of the socks, the socks are just detached from the tray and placed flat on the sock rack.

[0102] Step Six: While moving the second hand downwards, move the tray to the right simultaneously, controlling the movement speed of the second hand and the tray. When the socks separate from the tray, release the second hand. At this point, the socks are placed flat on the sock placement board.

[0103] Step 7: Repeat steps 1-6, stacking N layers of socks on the sock-placing board. Then, the conveyor mechanism on the board will send the N layers of socks to the next process for packaging and sorting.

[0104] The method of the present invention can realize the automatic detection of socks and the stacking of the detected socks, avoiding the time-consuming and labor-intensive manual detection and stacking processes, and greatly improving work efficiency.

[0105] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
