Abstract
Description
Technical Field
[0001] This invention relates to the field of weaving equipment technology, and in particular to a transfer device and weaving equipment that can reliably transfer fabric loops. Background Technology
[0002] In the production process of circular knitted fabrics such as socks, after the knitted fabric is knitted to the required size, it needs to be transferred to another production station for sealing and other sewing operations. That is, a transfer device is needed to transfer the unfinished knitted fabric. Specifically, the transfer device transfers the knitted fabric by transferring the knitting loops.
[0003] Existing transfer devices mainly consist of a slotted transfer needle and a pressure plate. The transfer of unfinished knitted fabric is achieved by placing the knitting needle within the groove of the transfer needle and by pushing the knitting loops on the needle onto the transfer needle using the pressure plate. However, this type of transfer device, which relies on the knitting needle and transfer needle overlapping, carries the risk of the knitting needle and transfer needle failing to overlap, or the knitting loops detaching from the needle. It cannot accurately transfer the knitting loops to the transfer needle, meaning that existing transfer devices cannot reliably transfer knitted fabric. Summary of the Invention
[0004] To address the above-mentioned problems, this invention proposes a transfer device and weaving equipment that can reliably transfer fabric loops.
[0005] The technical solution adopted in this invention is as follows:
[0006] This application provides a transfer device capable of reliably transferring fabric loops for transferring loops on knitting needles. The transfer device includes a transfer needle and a loop pushing needle.
[0007] The transfer needle has a transfer arm, and the end of the transfer arm has a pickup part, which is used to cooperate with the knitting needle to realize the transfer of the coil from the knitting needle to the transfer arm;
[0008] The pickup part has a through hole for engaging with the hook of the knitting needle. The lower end of the pickup part forming the through hole is a closed end. When the pickup part engages with the knitting needle to transfer the coil, the closed end is used to connect the knitting needle and the transfer needle.
[0009] When the needle tongue hinged to the needle engages with the needle hook, a closed loop is formed, and the closed end can be accommodated within the closed loop;
[0010] The coil pusher needle is used to push the coil to change or limit the position of the coil on the knitting needle or transfer needle.
[0011] Compared to existing overlapping mechanisms, the transfer device of this application features a through-hole in the pickup section of the transfer needle and a closed end at the lower end of the pickup section. This allows the hook of the knitting needle to pass through the through-hole for loop transfer. When the hook passes through the through-hole for loop transfer, the needle tongue and the hook of the knitting needle engage to form a closed loop. The closed end is perfectly accommodated within this closed loop. The pickup section with the through-hole, through its closed end and engagement with the closed loop, ensures a smooth transition of the loop from the hook or needle tongue to the transfer arm of the transfer needle, preventing the loop from slipping off the hook and thus ensuring a smooth transfer to the pickup section. In other words, the transfer device provided by this application can more reliably transfer knitted fabrics.
[0012] When it is necessary to use the transfer device provided in this application to transfer the loop on the knitting needle from the knitting needle to the next sewing needle that needs to perform the sewing head operation, the workflow includes:
[0013] Position the hook of the needle tongue in the through hole of the transfer needle;
[0014] The coil drives the needle to change the axial position of the coil on the knitting needle or transfer needle, and transfers the coil on the knitting needle to the transfer arm of the transfer needle through the pick-up part of the transfer needle;
[0015] The transfer needle is moved to the vicinity of the next toothed needle that needs to be sewn and engages with the toothed needle. The coil pusher needle moves to push the coil to the position of the transfer needle corresponding to the toothed needle. Finally, the transfer needle and the coil pusher needle are removed respectively to complete the transfer of the coil from the knitting needle to the toothed needle.
[0016] Furthermore, the through hole is a rectangular or elliptical hole structure, the height of the through hole is greater than the height of the hook, and the width of the through hole is greater than the thickness of the hook.
[0017] Furthermore, the specific size relationship between the through hole and the needle hook can be as follows: when the needle hook and the needle tongue are engaged on the pickup part of the transfer needle, there is a gap between the outer side wall of the needle hook and the upper side wall, left side wall and right side wall of the through hole, respectively, with a gap distance of 0.1mm~1mm; this setting allows the needle hook to pass smoothly through the through hole in actual use, so that the closed end is located inside the needle hook.
[0018] Furthermore, the closer to the very end of the pickup section, the smaller the dimension of the closed end along the width direction of the through hole. That is, the closed end is configured in a wedge-shaped or conical structure to guide the coil transfer.
[0019] Furthermore, the two sides of the closed end along the width direction of the through hole are two first inclined surfaces symmetrically arranged about the through hole, and the two first inclined surfaces are inclined towards the side closer to the through hole.
[0020] When the hook is located on the through hole, the closed end extends beyond the hook or the tongue along the width of the through hole. The arrangement of the two first inclined surfaces can guide the coil from the tongue or hook to the pickup part, thereby further improving the reliability of the transfer coil of the transfer device.
[0021] Furthermore, the angle between the first inclined surface and the height direction of the through hole is 10°~45°, preferably 15°~20°.
[0022] Furthermore, the transfer arm has two protruding thin plates, which form grooves with the sidewall of the transfer arm. These grooves provide space for the next toothed needle to be sewn.
[0023] Furthermore, each end of the protruding sheet is provided with a guide slope, and the guide slope is smoothly connected to the transfer arm. This arrangement facilitates the smooth sliding of the coil on the transfer arm.
[0024] Furthermore, the side of the closed end along the length of the through hole is a second inclined surface, which is inclined to the groove side. The second inclined surface is used to prevent the closed end from interfering with the engagement of the needle tongue and the needle hook.
[0025] Furthermore, the coil pushing needle includes a main body and an anti-detachment part connected to the main body. When the transfer needle moves out from the toothed needle that cooperates with the transfer needle, the anti-detachment part is used to prevent the coil from moving away with the transfer needle.
[0026] During the process of moving the coil on the transfer needle to the vicinity of the toothed needle and engaging with the toothed needle, the anti-detachment part is also used to limit the position of the coil and prevent the coil from detaching from the transfer needle and the coil push needle.
[0027] Furthermore, the coil pushing needle also includes a pushing part connected to the main body, the pushing part being used to support or push the coil;
[0028] The bottom end face of the pushing part is formed as a first pushing part;
[0029] The middle part of the pushing part has a V-shaped notch structure, and the notch structure is the second pushing part of the pushing part;
[0030] The top of the pushing part has a beveled structure, which is the third pushing part of the pushing part.
[0031] Furthermore, the anti-detachment part is a toothed structure protruding from the main body, with the toothed structure facing the pushing part. The anti-detachment part is located on the side of the third pushing part away from the first pushing part.
[0032] Furthermore, the transfer needle is a one-piece molded structure or welded.
[0033] Furthermore, the coil pusher needle is a one-piece molded structure.
[0034] Furthermore, the transfer needle also has a first mounting end, which is used to mount the transfer needle on a drive device that drives the transfer needle to move.
[0035] The coil pusher needle also has a second mounting end, which is used to mount the coil pusher needle on a drive device that drives the coil pusher needle to move.
[0036] Furthermore, the second mounting end is connected to the main body.
[0037] This application also provides a knitting device, including a transfer device, a knitting needle, and a sewing needle, wherein the knitting needle is used for knitting operations, the sewing needle is used for closing operations, and the transfer device is used for transferring the loops on the knitting needle to the sewing needle.
[0038] The transfer device is the aforementioned transfer device capable of reliably transferring fabric coils.
[0039] The beneficial effects of this invention are:
[0040] (1) The transfer device of this application provides a through hole in the pickup part of the transfer needle and forms a closed end at the lower end of the pickup part, allowing the needle hook of the knitting needle to pass through the through hole for loop transfer. When the needle hook passes through the through hole for loop transfer, the needle tongue and the needle hook of the knitting needle engage to form a closed loop, and the closed end is just accommodated in the closed loop. The pickup part with the through hole cooperates with the closed loop through the closed end, allowing the loop to smoothly transition from the needle hook or needle tongue to the transfer arm of the transfer needle, preventing the loop from slipping off the needle hook and thus preventing the loop from being smoothly transferred to the pickup part. That is, the transfer device provided by this application can more reliably realize the transfer of knitted fabric.
[0041] (2) Two first inclined surfaces are provided at the closed end to guide the coil from the needle tongue or hook to the pickup part, thereby further improving the reliability of the transfer coil of the transfer device. At the same time, guide inclined parts are provided at both ends of the protruding thin plate, which can also facilitate the smooth sliding of the coil on the transfer arm.
[0042] (3) An anti-detachment part is provided on the main body of the coil push needle. When the coil on the transfer needle is moved to the vicinity of the toothed needle and engages with the toothed needle, the anti-detachment part is also used to limit the position of the coil and prevent the coil from detaching from the transfer needle and the coil push needle. When the transfer needle is moved away from the toothed needle that engages with the transfer needle, the anti-detachment part can limit the coil from moving away with the transfer needle. That is, the transfer device provided in this application can further improve the reliability of coil transfer. Attached Figure Description

[0060] The present invention will now be described in detail with reference to the accompanying drawings.
[0061] like Figures 1-4 As shown, this application provides a transfer device capable of reliably transferring fabric loops for transferring loops 40 on a knitting needle 10. The transfer device includes a transfer needle 20 and a loop pushing needle 30.
[0062] The transfer needle 20 is formed with a transfer arm 220, and the end of the transfer arm 220 is formed with a pickup part 210. The pickup part 210 is used to cooperate with the knitting needle 10 to realize the transfer of the coil 40 from the knitting needle 10 to the transfer arm 220.
[0063] The pickup part 210 has a through hole 211, which is used to cooperate with the hook 110 of the knitting needle 10. The lower end of the pickup part 210 that forms the through hole 211 is a closed end 240. When the pickup part 210 cooperates with the knitting needle 10 to transfer the coil 40, the closed end 240 is used to connect the knitting needle 10 and the transfer needle 20.
[0064] When the needle tongue 120 hinged on the needle 10 engages with the needle hook 110, a closed loop is formed, and the closed end 240 can be accommodated within the closed loop.
[0065] The coil pusher needle 30 is used to push the coil 40 to change or limit the position of the coil 40 on the knitting needle 10 or the transfer needle 20.
[0066] Compared to existing overlapping joints, the transfer device of this application provides a through hole 211 in the pickup section 210 of the transfer needle 20 and a closed end 240 at the lower end of the pickup section 210. This allows the hook 110 of the knitting needle 10 to pass through the through hole 211 to transfer the loop 40. When the hook 110 passes through the through hole 211 to transfer the loop 40, the needle tongue 120 engages with the hook 110 of the knitting needle 10 to form a closed loop. The closed end 240 is perfectly accommodated within the closed loop. The pickup section 210 with the through hole 211, through the engagement of the closed end 240 with the closed loop, allows the loop 40 to smoothly transition from the hook 110 or the needle tongue 120 to the transfer arm 220 of the transfer needle 20, preventing the loop 40 from slipping off the hook 110 and thus failing to transfer smoothly to the pickup section 210. In other words, the transfer device provided by this application can more reliably achieve the transfer of knitted fabric.
[0067] When it is necessary to use the transfer device provided in this application to transfer the loop 40 on the knitting needle 10 from the knitting needle 10 to the next sewing needle 50 that needs to perform the sewing head operation, the workflow includes:
[0068] Position the hook 110 of the needle tongue 120 in the through hole 211 of the transfer needle 20;
[0069] The coil pushes the needle 30 to change the axial position of the coil 40 on the knitting needle 10 or the transfer needle 20, and the coil 40 on the knitting needle 10 is transferred to the transfer arm 220 of the transfer needle 20 through the pick-up part 210 of the transfer needle 20.
[0070] Move the transfer needle 20 to the vicinity of the next toothed needle 50 that needs to be sewn and engage with the toothed needle 50. The coil push needle 30 moves to push the coil 40 to the position of the transfer needle 20 corresponding to the toothed needle 50. Finally, remove the transfer needle 20 and the coil push needle 30 respectively to complete the transfer of the coil 40 from the coil 40 to the toothed needle 50.
[0071] In this embodiment, the through hole 211 is a rectangular hole structure, the height of the through hole 211 is greater than the height of the hook 110, and the width of the through hole 211 is greater than the thickness of the hook 110.
[0072] In other embodiments, the through hole can also be an elliptical hole structure, with the major axis of the through hole 211 being greater than the height of the hook 110, and the minor axis of the through hole 211 being greater than the thickness of the hook 110.
[0073] In this embodiment, the specific size relationship between the through hole 211 and the hook 110 can be as follows: when the hook 110 and the needle tongue 120 are engaged on the pickup part 210 of the transfer needle 20, there is a gap between the outer side wall of the hook 110 and the upper side wall, left side wall and right side wall of the through hole 211, respectively. The gap is preferably 0.1mm to 0.5mm. This setting allows the hook 110 to pass smoothly through the through hole 211 in actual use, and the closed end 240 is accommodated in the hook.
[0074] In this embodiment, the closer to the end of the pickup section 210, the smaller the dimension of the closed end 240 along the width direction of the through hole 211. That is, the closed end 240 is provided with a wedge-shaped or conical structure to guide the transfer of the coil 40.
[0075] In this embodiment, the two sides of the closed end 240 along the width direction of the through hole 211 are two first inclined surfaces 241 symmetrically arranged about the through hole 211, and the two first inclined surfaces 241 are inclined towards the side closer to the through hole 211.
[0076] When the hook 110 is located on the through hole 211, the closed end 240 extends beyond the hook 110 or the tongue 120 along the width direction of the through hole 211. The arrangement of the two first inclined surfaces 241 can guide the coil 40 from the tongue 120 or the hook 110 to the pickup part 210, so as to further improve the reliability of the transfer coil 40 of the transfer device.
[0077] In this embodiment, the angle between the first inclined surface 241 and the height direction of the through hole 211 is 10°~45°, preferably 15°~20°.
[0078] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the transfer arm 220 has two protruding thin plates 222, and the two protruding thin plates 222 and the side wall of the transfer arm 220 form a groove 223. The groove 223 is used to provide a space for the next sewing needle 50 that needs to be sewn.
[0079] Setting the groove 223 and positioning the toothed needle 50 within the groove 223 can prevent the wire from getting stuck, allowing for a smoother transfer of the coil 40.
[0080] In this embodiment, the two protruding thin plates 222 form a groove 223 with the front wall of the transfer arm 220, and the side wall of the transfer arm 220 furthest from the first mounting end 230 is the front wall of the transfer arm 220.
[0081] In this embodiment, the two ends of the protruding sheet 222 are respectively provided with guide slopes 2221, and the guide slopes 2221 are smoothly connected to the transfer arm 220. This arrangement facilitates the smooth sliding of the coil 40 on the transfer arm 220.
[0082] In this embodiment, the side of the closed end 240 along the length direction of the through hole 211 is a second inclined surface 242. The second inclined surface 242 is inclined towards the groove 223 and is used to prevent the closed end 240 from interfering with the engagement of the needle tongue 120 and the needle hook 110.
[0083] In this embodiment, the coil pusher needle 30 includes a main body 310 and an anti-detachment part 320 connected to the main body 310. When the transfer needle 20 moves off the toothed needle 50 that cooperates with the transfer needle 20, the anti-detachment part 320 is used to prevent the coil 40 from moving away with the transfer needle 20. That is, the coil pusher needle 30 is also used to control the relative position between the coil 40, the transfer needle 20 and the toothed needle 50.
[0084] During the process of moving the coil 40 on the transfer needle 20 to the vicinity of the toothed needle 50 and engaging with the toothed needle 50, the anti-detachment part 320 is also used to limit the position of the coil 40 and prevent the coil 40 from detaching from the transfer needle 20 and the coil push needle 30.
[0085] In this embodiment, the coil pushing needle 30 also includes a pushing part 330 connected to the main body 310, the pushing part 330 being used to support or push the coil 40;
[0086] The bottom end face of the propulsion part 330 is formed into the first propulsion part 331;
[0087] A V-shaped notch structure is formed in the middle of the pusher 330, and the notch structure is the second pusher 332 of the pusher 330;
[0088] The top of the pusher 330 has a beveled structure, which is the third pusher 333 of the pusher 330.
[0089] In this embodiment, the anti-detachment part 320 is a protruding tooth structure that protrudes from the main body part 310, with the protruding tooth structure facing the pushing part 330. The anti-detachment part 320 is disposed on the side of the third pushing part 333 away from the first pushing part 331.
[0090] In this embodiment, the tooth tip (i.e., the anti-detachment part 320) of the convex tooth structure is positioned at the position closest to the top of the third push part 333 of the push part.
[0091] In this embodiment, the transfer needle 20 is a one-piece molded structure.
[0092] In other embodiments, the transfer needle can also be welded into shape, specifically, it can be a three-part weld of two thin sheets and the transfer needle body.
[0093] In this embodiment, the coil pusher needle 30 is a one-piece molded structure.
[0094] In this embodiment, the transfer needle 20 also has a first mounting end 230, which is used to mount the transfer needle 20 on a driving device that drives the transfer needle 20 to move.
[0095] The coil push pin 30 also has a second mounting end 340, which is used to mount the coil push pin 30 on a drive device that drives the coil push pin 30 to move.
[0096] In this embodiment, the second mounting end 340 is connected to the main body 310.
[0097] like Figures 1-4 As shown, this application also provides a knitting device, including a transfer device, a knitting needle 10 and a sewing needle 50. The knitting needle 10 is used for knitting operations, the sewing needle 50 is used for closing operations, and the transfer device is used to transfer the loop 40 on the knitting needle 10 to the sewing needle 50.
[0098] The transfer device is one of the aforementioned transfer devices capable of reliably transferring fabric coils.
[0099] like Figures 1-15 As shown, the specific working process of the transfer device or weaving equipment provided in this application is as follows:
[0100] like Figure 5 As shown, the coil 40 to be transferred is located at the hook 110 of the knitting needle 10, the transfer needle 20 and the coil push needle 30 are located beside the knitting needle 10, and the first push part 331 of the coil push needle 30 is located above the coil 40.
[0101] like Figure 6 As shown, the control coil pushes the needle 30 downward, and the first pusher 331 of the control coil pushes the coil 40 inside the needle hook 110 to below the end of the needle hook 110. During this process, the needle tongue 120 is opened, so that the tip of the needle tongue 120 faces downward. The control transfer needle 20 is moved downward, so that the through hole 211 of the transfer needle 20 is aligned with the needle hook 110 of the knitting needle 10.
[0102] like Figure 7 As shown, the transfer needle 20 is controlled to move closer to the knitting needle 10, so that the hook 110 of the knitting needle 10 extends into the through hole 211 of the transfer needle 20 and engages with the pickup part 210 of the transfer needle 20. At this time, the closed end of the transfer needle 20 is accommodated in the closed loop formed when the needle tongue and the hook of the knitting needle are engaged.
[0103] like Figure 8 As shown, adjust the position of the coil push needle 30, first make the coil 40 located on the second push part 332 of the coil push needle 30, control the coil push needle 30 to move upward, and push the coil 40 to below the hinge part between the knitting needle and the needle tongue through the second push part 332 of the coil push needle 30.
[0104] like Figure 9 As shown, continue adjusting the position of the coil pusher needle 30 so that the third pusher part 333 of the coil pusher needle 30 corresponds to the coil 40. Control the coil pusher needle 30 to move upward, so that the coil 40 is transferred from the needle hook 110 to the transfer arm 220 of the transfer needle 20 through the third pusher part 333. At this time, under the action of the coil 40, the closed loop formed by the needle tongue 120 and the needle hook 110 is just accommodated in the closed loop by the closed end of the transfer needle 20, so that the coil slides smoothly onto the transfer needle 20.
[0105] like Figure 10 As shown, the transfer needle 20 is controlled to move away from the knitting needle 10, so that the coil 40 is held in place by the coil push needle 30 and the transfer needle 20, thereby protecting the coil by the coil push needle 30 and the transfer needle 20, so that the transfer needle 20 and the coil push needle 30 can move the coil 40 together away from the knitting needle 10 in the next step.
[0106] like Figure 11 As shown, the coil pushes the needle 30, the transfer needle 20 and the coil 40 together to the vicinity of the next toothed needle 50 that needs to be sewn.
[0107] like Figure 12 As shown, the control coil pushes the needle 30 and the transfer needle 20 to move closer to the toothed needle 50, so that the toothed needle 50 and the transfer arm 220 of the transfer needle 20 are positioned correspondingly and the toothed needle 50 is positioned directly above the groove 223.
[0108] like Figure 13 As shown, the control coil pushes the needle 30 and the transfer needle 20 upward, and the toothed needle 50 is inserted into the groove 223 of the transfer needle 20.
[0109] like Figure 14 As shown, the transfer needle 20 continues to move upward while the coil push needle 30 remains in the same position. With the assistance of the anti-detachment part 320 of the coil push needle 30, the coil 40 is transferred to the toothed needle 50.
[0110] like Figure 15 As shown, the control coil pushes the needle 30 and the transfer needle 20 to move away from the toothed needle 50, completing one transfer of the coil 40 from the hook 110 to the toothed needle 50.
[0111] The above description is merely a preferred embodiment of the present invention and does not limit the scope of patent protection of the present invention. Any equivalent structural transformations made based on the description and drawings of the present invention, whether directly or indirectly applied to other related technical fields, are similarly included within the scope of protection of the present invention.

When the pickup part engages with the knitting needle to transfer the coil, the closed end is used to connect the knitting needle and the transfer needle. When the needle tongue hinged to the needle engages with the needle hook, a closed loop is formed, and the closed end can be accommodated within the closed loop; The coil pusher needle includes a main body and an anti-detachment part and a pusher part connected to the main body. The pushing part is used to push the coil to change or limit the position of the coil on the knitting needle or transfer needle; When the transfer needle is removed from the toothed needle that mates with the transfer needle, the anti-detachment part is used to prevent the coil from moving away with the transfer needle; The end of the anti-detachment part does not extend beyond the pushing part; The method for transferring coils using the braiding device includes: Position the coil to be transferred at the hook of the knitting needle, with the transfer needle and the coil push needle positioned beside the knitting needle and the coil push needle positioned above the coil. Control the coil push needle to push the coil inside the hook to below the end of the hook, so that the latch is opened and the tip of the latch faces downward. The through hole of the transfer needle is controlled to be aligned with the hook of the knitting needle, and the transfer needle is controlled to move towards the side closer to the knitting needle, so that the hook of the knitting needle extends into the through hole of the transfer needle and cooperates with the pickup part of the transfer needle, so that the closed end of the transfer needle is accommodated in the closed loop formed when the needle tongue and the hook of the knitting needle are engaged; Adjust the position of the coil push needle, first position the coil on the coil push needle, control the coil push needle to move upward, and push the coil to below the hinge of the knitting needle and the needle tongue through the coil push needle; Adjust the position of the coil pusher pin so that the coil pusher pin is aligned with the coil. Control the coil pusher pin to move upward so that the coil is transferred from the hook to the transfer arm of the transfer needle via the coil pusher pin. At this time, under the action of the coil, the closed loop formed by the needle tongue and the hook is just accommodated in the closed loop by the closed end of the transfer needle, so that the coil slides smoothly to the transfer needle. Control the transfer needle to move away from the knitting needle, so that the coil is locked by the coil-pushing needle and the transfer needle; Control the coil to move the entire coil, including the push needle, the transfer needle, and the coil, to the vicinity of the next toothed needle where a sewing operation is required.
