Description

Technical Field

[0001] The invention belongs to the technical field of knitting machinery and relates to a novel transfer device. Background Art

[0002] When producing socks, generally, semi-finished socks are first produced in the needle cylinder of the sock machine, at which time the toes of the socks are not sewn, and then the semi-finished socks are taken out of the needle cylinder by a transfer device and transferred to a toe sewing disc, and then the toes of the socks are sewn by the toe sewing machine. The transfer device includes a transfer needle arranged on a transfer disc body. The transfer needle moves radially along the transfer disc body under the drive of the drive mechanism and cooperates with the vertical knitting needle of the sock machine to perform the sock thread transfer operation.

[0003] The existing transfer needle drive mechanism has poor driving accuracy and driving stability, which can easily lead to transfer needle missing, hanging loops, and needle falling off, and due to poor positioning accuracy and precision control or external influences such as driving methods, the transfer needle is very prone to position deviations during radial movement, which seriously affects the quality of the product, increases the defective rate, increases equipment and material losses, and requires frequent shutdowns for adjustments, resulting in a decrease in production efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a novel transfer device in view of the above problems.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A novel transfer device comprises a transfer disk, wherein the transfer disk is provided with a plurality of transfer needles which are distributed along its circumference and can move horizontally along its radial direction, a return force-applying part is provided on the transfer needle, the transfer needle is suspended on the bottom of the transfer disk through a slider rail structure, a force-bearing part is provided on the transfer needle, the force-bearing part passes through a movable groove of the force-bearing part of the transfer disk and is exposed outside the top of the transfer disk, at least three radial push plates which are distributed along the circumference are provided on the top of the transfer disk, and when the radial push plates move outward, they can act on the force-bearing part to push the transfer needles to move radially outward, and the radial push plates are connected to a radial driving mechanism.

[0006] The radial driving mechanism can synchronously drive the radial push plate to move radially outward along the transfer disk. The radial push plate can evenly act on the force-bearing part of each transfer needle, so that each transfer needle is evenly stressed, so that each transfer needle can move radially outward at a uniform and stable speed. The driving precision is poor and the driving stability is good. The slider and rail structure can limit the transfer needle so that it can only move horizontally along the radial direction of the transfer disk, which can ensure that no deviations in other positions will occur during the radial movement of the transfer needle, so as to achieve precision control, facilitate precise control of the position of the transfer needle, ensure accurate operation, reduce the complexity of operation, reduce the risk of error, and ensure the quality and efficiency of the sock thread transfer operation.

[0007] In the above-mentioned new transfer device, the radial driving mechanism includes an eccentric wheel, a radial movement guide assembly is provided between the radial push plate and the transfer disk, the ends of the two adjacent radial push plates are overlapped with each other, and the ends of the radial push plates at the overlapping parts are provided with strip holes, the eccentric body of the eccentric wheel is arranged in the strip hole, and when the eccentric wheel rotates, it can drive the radial push plate to move radially, and the eccentric wheel is connected to the eccentric wheel driving assembly.

[0008] The eccentric wheel driving assembly can drive the eccentric wheel to rotate. When the eccentric wheel rotates, the eccentric body of the eccentric wheel acts on the strip hole of the radial push plate to drive the radial push plate to move radially along the transfer disk. The radial movement guide assembly plays a role of radial movement guide during the radial movement of the radial push plate along the transfer disk, ensuring that the moving position of the radial push plate will not deviate, so that the radial push plate can act evenly on the force-bearing part of each transfer needle to achieve precision control, facilitate precise control of the position of the transfer needle, and ensure accurate operation.

[0009] In the above-mentioned novel transfer device, the eccentric wheel driving assembly includes an outer tooth body arranged on the main wheel of the eccentric wheel, a plurality of outer tooth bodies are connected to a driving tooth ring, and the driving tooth ring is connected to a tooth ring driving unit.

[0010] The gear ring driving unit can drive the driving gear ring to rotate, and the driving gear ring is meshed with the outer gear body for transmission. When the driving gear ring rotates, it can drive the main wheel of the eccentric wheel to rotate, thereby driving the radial push plate to move radially.

[0011] In the above-mentioned novel transfer device, the bottom and top of the main wheel are respectively in contact with and connected to the radial push plate and the annular cover plate, and the central axis of the main wheel is passed through the annular cover plate and can rotate between the radial push plate and the annular cover plate; The bottom of the driving gear ring is in contact with and connected to the upper surface of the radial push plate and the inner step on the inner side of the positioning plate of the transfer plate, and the upper surface of the driving gear ring is in contact with and connected to the annular cover plate; The annular cover plate is fixed on the transfer disk.

[0012] The central axis of the main wheel is passed through the annular cover plate and can rotate between the radial push plate and the annular cover plate. The annular cover plate and the central axis play a role in positioning the main wheel. The inner step on the inner side of the positioning plate plays a role in rotational positioning of the driving gear ring to ensure the rotation accuracy of the driving gear ring.

[0013] In the above-mentioned novel transfer device, the radial movement guide assembly includes a radial strip groove arranged on the radial push plate, and a positioning pin fixed on the transfer disk is penetrated through the radial strip groove.

[0014] The locating pin on the transfer disk is inserted into the radial strip groove. The locating pin cooperates with the radial strip groove to guide the radial movement of the radial push plate during the radial movement of the radial push plate along the transfer disk, ensuring that the moving position of the radial push plate will not deviate, thereby ensuring the moving accuracy of the radial push plate.

[0015] In the above-mentioned new transfer device, an arc-shaped inclined plate which is gradually inclined outward from top to bottom is provided on the outer side of the radial push plate, and an annular groove is provided between several movable grooves of the force-bearing part and the top of the transfer plate. The upper end of the force-bearing part and the arc-shaped inclined plate are arranged in the annular groove, and the outer end of the arc-shaped inclined plate is against the inner side of the force-bearing part.

[0016] When the radial push plate moves radially outward along the transfer disk, the arc-shaped inclined plate outside the radial push plate acts on the force-bearing part of the transfer needle to push the transfer needle to move radially outward along the transfer disk.

[0017] In the above-mentioned novel transfer device, the gear ring drive unit includes a drive connecting ear arranged on the outer wall of the drive gear ring, and the drive connecting ear can be connected to the gear ring rotation driver.

[0018] The gear ring rotation driver runs through the drive connecting ear and can drive the drive gear ring to rotate.

[0019] In the above-mentioned new transfer device, the slider rail structure includes a slide groove arranged at the bottom of the transfer disk and extending radially therefrom, a slider is arranged in the slide groove, the bottom of the slider is fixed to the top of the transfer needle, and a transfer needle anti-sway groove is arranged between the slide groove and the bottom of the transfer disk to enable the transfer needle to move radially along the transfer disk, the force-bearing part is arranged on the rear end of the transfer needle, and the front end of the transfer needle is a hook tongue.

[0020] During the radial movement of the transfer needle along the transfer disk, the slide groove at the bottom of the transfer disk cooperates with the slider on the top of the transfer needle to limit the transfer needle so that it can only move horizontally along the radial direction of the transfer disk, which can ensure that there will be no deviations in other positions during the radial movement of the transfer needle, so as to achieve precision control and facilitate accurate control of the position of the transfer needle. The transfer needle anti-sway groove is used to accommodate the transfer needle and allow it to move radially along the transfer disk, which can effectively avoid shaking of the transfer needle during movement, so as to achieve precision control and ensure that the transfer needle position will not deviate.

[0021] In the above-mentioned new transfer device, the outer end of the slider is sleeved on the force-bearing part and connected to the transfer needle through a mortise and tenon structure. The inner end of the slider is provided with a hole groove, and the positioning column on the top of the transfer needle is passed through the hole groove, and a convenient gap is left between the hole groove and the positioning column so that the slider can move axially after the positioning column is inserted into the hole groove so that the mortise and tenon structure can be locked. The slider, the positioning column and the transfer needle are welded, bonded or clamped in the gap.

[0022] The slider is fixedly connected to the transfer needle through a mortise and tenon structure, and is firmly fixed. The positioning post on the top of the transfer needle is inserted into the hole groove at the front end of the slider and cooperates with the hole groove to play a positioning role. The gap left between the hole groove and the positioning post facilitates the locking of the mortise and tenon structure. The slider, the positioning post and the transfer needle are welded, bonded or clamped in the gap to ensure a firm connection.

[0023] In the above-mentioned novel transfer device, the mortise and tenon structure includes a tenon provided on one end of the slider, the force-bearing portion is located on the rear end of the transfer needle, the tenon is sleeved on the force-bearing portion and after being sleeved, the slider can be axially moved to make one end of it snap into the tenon of the force-bearing portion, and the other end of the slider is fixedly connected to the transfer needle; A reinforcing rib is provided on the side of the force-bearing part away from the mortise. The reinforcing rib is connected to the transfer pin and the force-bearing part as a whole. A gap is formed between the mortise and the reinforcing rib. The reinforcing rib, the slider and the transfer pin are welded, bonded or clamped in the gap.

[0024] The reinforcement ribs on the force-bearing part cooperate with the tenon of the slider to strengthen the connection strength between the slider and the transfer needle, thereby further ensuring a stable connection between the slider and the transfer needle. The gap between the tenon and the reinforcement ribs facilitates the locking of the mortise and tenon structure. The reinforcement ribs are welded, bonded or clamped to the slider and the transfer needle in the gap, which can ensure the stability of the connection between the slider and the transfer needle.

[0025] In the above-mentioned novel transfer device, the transfer needle is in the form of a sheet, the maximum width of the slider is greater than the width of the transfer needle, one side of the slider is flush with the side surface of the transfer needle, and the other side protrudes from the side wall of the transfer needle; Alternatively, both sides of the slider protrude from the side walls on both sides of the transfer needle respectively.

[0026] The maximum width of the slider is greater than the width of the transfer pin to ensure a secure connection between the slider and the transfer pin.

[0029] Compared with the existing technology, the advantages of the present invention are: 1. The radial push plate can act evenly on the force-bearing part of each transfer needle, and each transfer needle can move radially outward at a uniform and stable speed with balanced force, and the driving accuracy and driving stability are good. 2. The transfer needle can only move horizontally along the radial direction of the transfer disk, which can ensure that there will be no deviation in other positions during the radial movement of the transfer needle, so as to achieve precision control, facilitate accurate control of the position of the transfer needle, and ensure the quality and efficiency of the sock thread transfer operation. 3. The radial push plate will not deviate from the moving position during the radial movement, and the driving accuracy is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In the present invention, the radial driving mechanism 8 can synchronously drive the radial pushing plate 7 to move radially outward along the transfer disk 1. When the radial pushing plate 7 moves radially outward along the transfer disk 1, it can act on the force-bearing part 5 of the transfer needle 2 to push the transfer needle 2 to move radially outward along the transfer disk 1. The return force-applying part 3 on the transfer needle 2 can reset the transfer needle 2 so that the transfer needle 2 moves radially inward along the transfer disk 1 and resets. During the radial movement of the transfer needle 2 along the transfer disk 1, it cooperates with the vertical knitting needles of the sock machine to perform the sock thread transfer operation.

[0034] The radial driving mechanism 8 can synchronously drive the radial pushing plate 7 to move radially outward along the transfer disk 1. The radial pushing plate 7 can evenly act on the force-bearing part 5 of each transfer needle 2, so that each transfer needle 2 is evenly stressed, so that each transfer needle 2 can move radially outward at a uniform and stable speed, with poor driving precision and good driving stability. The transfer needle 2 is suspended at the bottom of the transfer disk 1 through the slider rail structure 4. The slider rail structure 4 can limit the transfer needle 2 so that it can only move horizontally along the radial direction of the transfer disk 1, and can ensure that no deviations at other positions will occur during the radial movement of the transfer needle 2, so as to achieve precision control, facilitate accurate control of the position of the transfer needle 2, ensure accurate operation, reduce the complexity of operation, reduce the risk of errors, and ensure the quality and efficiency of the sock thread transfer operation.

[0036] The eccentric wheel driving assembly 12 can drive the eccentric wheel 9 to rotate. When the eccentric wheel 9 rotates, the eccentric body 13 of the eccentric wheel 9 acts on the strip hole 11 of the radial push plate 7 to drive the radial push plate 7 to move radially along the transfer disk 1. The radial movement guide assembly 10 between the radial push plate 7 and the transfer disk 1 plays a role of radial movement guide during the radial movement of the radial push plate 7 along the transfer disk 1, ensuring that the moving position of the radial push plate 7 will not deviate, so that the radial push plate 7 can act evenly on the force-bearing part 5 of each transfer needle 2 to achieve precision control, facilitate precise control of the position of the transfer needle 2, and ensure accurate operation.

[0037] Specifically, combined with Figure 1-Figure 3 As shown, the eccentric wheel drive assembly 12 includes an outer tooth body 15 arranged on the main wheel 14 of the eccentric wheel 9, and a plurality of outer tooth bodies 15 are connected to a driving gear ring 16, and the driving gear ring 16 is connected to a gear ring drive unit 17. The gear ring drive unit 17 includes a driving connecting ear 26 arranged on the outer wall of the driving gear ring 16, and the driving connecting ear 26 can be connected to the gear ring rotation driver.

[0038] The gear ring rotation driver can drive the driving gear ring 16 to rotate through the driving connecting ear 26. The driving gear ring 16 is meshed with the outer gear body 15 for transmission. When the driving gear ring 16 rotates, it can drive the main wheel 14 of the eccentric wheel 9 to rotate, thereby driving the radial push plate 7 to move radially.

[0039] Specifically, combined with Figure 1-Figure 3 As shown, the bottom and top of the main wheel 14 are in contact with and connected to the radial push plate 7 and the annular cover plate 18 respectively, and the central axis 19 of the main wheel 14 is passed through the annular cover plate 18 and can rotate between the radial push plate 7 and the annular cover plate 18; The bottom of the driving gear ring 16 is in contact with and connected to the upper surface of the radial push plate 7 and the inner step 21 on the inner side of the positioning plate 20 of the transfer plate 1, and the upper surface of the driving gear ring 16 is in contact with and connected to the annular cover plate 18; The annular cover plate 18 is fixed on the transfer plate 1 .

The annular cover plate 18 and the central axis 19 play a role in positioning the main wheel 14. The inner step 21 on the inner side of the positioning plate 20 plays a role in rotational positioning of the driving gear ring 16 to ensure the rotation accuracy of the driving gear ring 16.

[0041] Specifically, combined with Figure 2 , Figure 3 and Figure 5 As shown, the radial movement guide assembly 10 includes a radial strip groove 22 arranged on the radial push plate 7, and a positioning pin 23 fixed on the transfer plate 1 is penetrated in the radial strip groove 22.

[0042] The locating pin 23 on the transfer disk 1 is penetrated by the radial strip groove 22. The locating pin 23 cooperates with the radial strip groove 22 to guide the radial movement of the radial push plate 7 during the radial movement of the radial push plate 7 along the transfer disk 1, thereby ensuring that the moving position of the radial push plate 7 will not deviate, thereby ensuring the moving accuracy of the radial push plate 7.

[0043] Specifically, combined with Figure 2 , Figure 3 and Figure 5 As shown, an arc-shaped inclined plate 24 which is gradually inclined outward from top to bottom is provided on the outer side of the radial push plate 7, an annular groove 25 is provided between the movable grooves 6 of the force-bearing part and the top of the transfer plate 1, the upper end of the force-bearing part 5 and the arc-shaped inclined plate 24 are arranged in the annular groove 25, and the outer end of the arc-shaped inclined plate 24 abuts against the inner side of the force-bearing part 5.

[0044] When the radial push plate 7 moves radially outward along the transfer disk 1 , the arc-shaped inclined plate 24 outside the radial push plate 7 acts on the force-bearing portion 5 of the transfer needle 2 to push the transfer needle 2 to move radially outward along the transfer disk 1 .

[0046] The slider 28 at the top of the transfer needle 2 is arranged in the slide groove 27 of the transfer disk 1, and the transfer needle 2 is arranged in the transfer needle anti-sway groove 29 of the transfer disk 1. When the radial push plate 7 moves outward synchronously, it can act on the force-bearing part 5 of each transfer needle 2 to drive the transfer needle 2 to move radially outward along the transfer disk 1 in the transfer needle anti-sway groove 29. The return force-applying part 3 on the transfer needle 2 can reset the transfer needle 2. During the radial movement of the transfer needle 2 along the transfer disk 1, the hook tongue 30 at the front end cooperates with the vertical knitting needle of the sock machine to perform the sock thread transfer operation.

[0047] During the radial movement of the transfer needle 2 along the transfer disk 1, the slide groove 27 at the bottom of the transfer disk 1 cooperates with the slider 28 on the top of the transfer needle 2 to limit the transfer needle 2 so that it can only move horizontally along the radial direction of the transfer disk 1, which can ensure that there will be no deviations in other positions during the radial movement of the transfer needle 2, so as to achieve precision control and facilitate accurate control of the position of the transfer needle 2. The transfer needle anti-sway groove 29 is used to accommodate the transfer needle 2 and allow it to move radially along the transfer disk 1, which can effectively avoid shaking of the transfer needle 2 during the movement of the transfer needle 2, so as to achieve precision control and ensure that there will be no deviation in the position of the transfer needle position 2.

[0048] Specifically, combined with Figure 7-Figure 9As shown, the outer end of the slider 28 is sleeved on the force-bearing part 5 and connected to the transfer needle 2 through the mortise and tenon structure 31. The inner end of the slider 28 is provided with a hole groove 32.

The slider 28, the positioning column 33 and the transfer needle 2 are welded, bonded or clamped in the gap 34.

[0049] The slider 28 is fixedly connected to the transfer needle 2 via the mortise and tenon structure 31 and is firmly fixed.

[0050] The positioning post 33 at the top of the transfer needle 2 is inserted into the hole groove 32 at the front end of the slider 28 and cooperates with the hole groove 32 to play a positioning role.

The reinforcing rib 43, the slider 28 and the transfer needle 2 are welded, bonded or clamped in the gap 44.

[0052] The tenon 38 on one end of the slider 28 is sleeved on the force-bearing part 5 of the transfer needle 2, and after the tenon 38 is sleeved into the force-bearing part 5, the slider 28 is axially moved so that one end of the tenon 38 is inserted into the mortise 39 of the force-bearing part 5. The mortise 39 of the force-bearing part 5 cooperates with one end of the tenon 38, which can ensure a stable connection between the slider 28 and the transfer needle 2.

[0053] The reinforcing rib 43 is, for example, rectangular, triangular, or braced. In this embodiment, the reinforcing rib 43 is rectangular and the top of the reinforcing rib 43 is flush with the top of the slider 28 .

[0057] One side of the slider 28 is flush with the side of the transfer needle 2, and the other side protrudes from the side wall of the transfer needle 2. The cross-section of the slider 28 and the transfer needle 2 is in an inverted L shape, and the cross-section of the slide groove 27 on the transfer plate 1 and the transfer needle anti-sway groove 29 is in an inverted L shape adapted thereto; Alternatively, both sides of the slider 28 protrude from the side walls of the transfer needle 2, the sections of the slider 28 and the transfer needle 2 are T-shaped, and the sections of the slide groove 27 on the transfer plate 1 and the transfer needle anti-sway groove 29 are T-shaped to adapt thereto.
