Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of sock knitting machines, and particularly to a seam transfer device for an open - end sock knitting machine and a using method thereof. Background Art

[0002] A sock knitting machine is a machine used to knit socks.

[0003] Currently, the latest fully automatic sock knitting machines are equipped with a seaming mechanism, and mechanisms such as sock knitting, transfer, and seaming are integrated. After the socks are knitted, they are directly seamed by the seaming mechanism to complete the shaping of the socks.

[0004] However, there are still a large number of open - end sock knitting machines on the market. After the socks are knitted on the open - end sock knitting machine, the operator takes the socks off the sock knitting machine and then seams the socks through a manual seaming machine to complete the final shaping of the socks.

[0005] The inventors of the present application found that for the socks produced by the existing open - end sock knitting machines, the seaming efficiency is relatively low and it is not suitable for automated production. Summary of the Invention

[0006] The purpose of the present invention is to provide a seam transfer device for an open - end sock knitting machine and a using method thereof to solve the problems in the above - mentioned background art.

[0007] The embodiments of the present invention provide a seam transfer device for an open - end sock knitting machine, including: a frame, a transfer and flipping disk, a crochet hook, a press needle, a crochet - hook driving mechanism, a press - needle driving mechanism, and a driving motor;

[0008] The driving motor and the transfer and flipping disk are arranged on the frame, and the driving motor is in transmission connection with the transfer and flipping disk for driving the transfer and flipping disk to rotate;

[0009] A plurality of first accommodating grooves are evenly distributed on the circumferential side wall of the transfer and flipping disk, and the crochet hook and the press needle are arranged in each first accommodating groove;

[0010] The crochet - hook driving mechanism and the press - needle driving mechanism are respectively arranged on the frame;

[0011] The crochet - hook driving mechanism is used to rotate the crochet hook, and when the crochet hook rotates, it is used to hook the socks on the sock knitting machine. The press - needle driving mechanism is used to move the press needle up and down, and when the press needle moves downward, it is used to fix the socks on the crochet hook so that the socks are transferred from the sock knitting machine to the transfer and flipping disk;

[0012] The transfer and flipping disk includes: a transfer disk and a flipping disk;

[0013] Both the transfer disk and the flipping disk are semi-circular. The transfer disk is fixedly arranged on the frame, and the flipping disk is rotatably arranged on the frame. The transfer disk and the flipping disk are spliced into the transfer and flipping disk, and after the flipping disk is flipped, it overlaps directly below the transfer disk to sew the socks through a sock seaming machine.

[0014] Based on the above solution, it can be seen that the sock seaming and transferring device for an open-toe sock knitting machine of the present invention is provided with a frame, a transfer and flipping disk, a crochet hook, a presser needle, a crochet hook driving mechanism, a presser needle driving mechanism, and a driving motor.

Then, the crochet hook driving mechanism pushes the crochet hook to rotate, and the crochet hook hooks the socks on the sock knitting machine. The presser needle driving mechanism drives the presser needle to move downward, and the presser needle cooperates with the crochet hook to control the socks, thereby transferring the socks on the sock knitting machine to the transfer and flipping disk. Then, the flipping disk flips 180 degrees along the position of the rotation axis. When flipping, half of the coil at the sole of the sock will approach the half of the coil at the instep along with the flipping disk until half of the coil at the sole of the sock fits with half of the coil at the instep.

[0062] As described in the background art of this application, there are still a large number of open - toe hosiery machines on the market. After the socks are knitted, the operator takes the socks off the open - toe hosiery machine and then sews the socks with a manual seaming machine to complete the sock forming.

[0063] The inventors of this application found that the socks produced by existing open - toe hosiery machines have a low seaming efficiency and are not suitable for automated production.

[0064] To solve the above problems, the inventors of this application proposed the technical solution of this application. The specific embodiments are as follows:

[0065] Embodiment 1

[0067] like Figures 1 to 10 As shown, the seam transfer device for an open sock machine of this embodiment includes: a frame 1, a transfer turning plate 2, a hook 3, a presser 4, a hook drive mechanism 5, a presser drive mechanism 6 and a drive motor.

[0068] One side of the frame 1 is disposed on a support shaft 11 , and the frame 1 can rotate around the support shaft 11 and can move up and down along the support shaft 11 .

[0069] The driving motor (not shown) is arranged on the frame 1. The transfer flip plate 2 is in a circular shape and is rotatably arranged on the frame 1. The transfer flip plate 2 is connected to the driving motor through a transmission mechanism. The driving motor is used to drive the transfer flip plate 2 to rotate.

[0070] A plurality of first accommodating grooves are evenly arranged on the circumferential side wall of the transfer reversing disk 2, and the first accommodating grooves are arranged along the axial direction of the transfer reversing disk 2. The number of the hook needle 3 and the press needle 4 is the same, and a hook needle 3 and a press needle 4 are arranged in each first accommodating groove of the transfer reversing disk 2, and the hook needle 3 and the press needle 4 in each first accommodating groove are arranged in close contact. The number of the hook needle 3 and the press needle 4 on the transfer reversing disk 2 may be less than the number of the sock needles 820 of the sock machine. Preferably, the number of the hook needle 3 and the press needle 4 corresponds to the number of the sock needles 820 of the sock machine. The hook needle 3 is rotatably arranged in the first accommodating groove of the transfer reversing disk 2, and one end of the hook needle 3 protrudes from the first accommodating groove of the transfer reversing disk 2, and the press needle 4 is arranged in the first accommodating groove of the transfer reversing disk 2 so as to be movable up and down.

[0071] The hook needle driving mechanism 5 and the pressing needle driving mechanism 6 are respectively arranged on the frame 1 .

[0072] The hook drive mechanism 5 is used to push the hook 3 to rotate the hook 3, and the hook 3 is used to hook the sock 810 on the sock machine when rotating. The press needle drive mechanism 6 is used to drive the press needle 4 to move up and down, and the press needle 4 is used to fix the sock on the hook 3 when moving downward, so that the sock 810 is locked between the hook 3 and the press needle 4, so that the sock is controlled by the hook 3 and the press needle 4, so as to realize the transfer of the sock from the sock needle of the sock machine to the transfer turning plate 2; the press needle 4 releases the sock when moving upward, and then the hook 3 rotates in the opposite direction to release the hooked sock.

[0073] The transfer and turnover disk 2 includes: a transfer disk 21 and a turnover disk 22.

[0074] Both the transfer disk 21 and the turnover disk 22 are semi-circular. The transfer disk 21 is fixedly arranged on the frame 1, and the turnover disk 22 is rotatably arranged on the frame 1.

[0075] The transfer disk 21 is designed in the structure of a 180-degree sock knitting cylinder 830, and half of the number of latch needles 3 and presser needles 4 are provided on the transfer disk 21; the turnover disk 22 is also designed in the structure of a 180-degree sock knitting cylinder, and the same half of the number of latch needles 3 and presser needles 4 are provided on it. The transfer disk 21 and the turnover disk 22 are spliced to form an annular transfer and turnover disk 2. After the sock is transferred onto the transfer and turnover disk 2, the turnover disk 22 is turned 180 degrees along the position of the rotation axis. Since the sock is firmly controlled by the latch needles 3 and the presser needles 4, when the turnover disk 22 is turned, half of the coils on the sole of the sock will approach the half of the coils on the instep along with the turnover disk 22 until reaching the 180-degree position, and half of the coils on the sole of the sock are attached to half of the coils on the instep. Then the frame 1 drives the transfer and turnover disk 2 to rotate, and moves the transfer and turnover disk 2 to the position of the seaming machine 840, and then the seaming machine 840 can seam the sock 810.

[0076] It can be easily found from the above content that the seaming and transfer device for an open sock knitting machine in this embodiment, by setting a frame, a transfer and turnover disk, latch needles, presser needles, a latch needle driving mechanism, a presser needle driving mechanism and a driving motor, the driving motor and the transfer and turnover disk are arranged on the frame, the transfer and turnover disk is evenly provided with a plurality of first accommodation grooves, latch needles and presser needles are arranged in each first accommodation groove, the latch needle driving mechanism and the presser needle driving mechanism are respectively arranged on the frame, the latch needle driving mechanism is used to rotate the latch needles, and the presser needle driving mechanism is used to move the presser needles up and down to fix the sock on the latch needles. The transfer and turnover disk includes: a transfer disk and a turnover disk. After the turnover disk is turned 180 degrees, it is stacked directly below the transfer disk to seam the sock through the seaming machine. For the seaming and transfer device for an open sock knitting machine in this embodiment, after the sock is knitted, the frame drives the transfer and turnover disk to move to directly above the sock knitting cylinder, then the latch needle driving mechanism pushes the latch needles to rotate, the latch needles hook the sock on the sock knitting machine, the presser needle driving mechanism drives the presser needles to move downward, and the presser needles cooperate with the latch needles to control the sock, so as to transfer the sock on the sock knitting machine to the transfer and turnover disk; then the turnover disk is turned 180 degrees along the position of the rotation axis, and when it is turned, half of the coils on the sole of the sock will approach the half of the coils on the instep along with the turnover disk until half of the coils on the sole of the sock are attached to half of the coils on the instep; then the frame moves the transfer and turnover disk to the position of the seaming machine, and the seaming machine seams the sock to complete the forming operation of the sock. The forming speed of the sock is fast and it is suitable for automated production.

[0077] Optionally, as Figure 2 、Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 10 As shown in Figure 7 and Figure 10 , the seam head transfer device for an open - toe hosiery machine in this embodiment further includes: a wire loop 7.

[0078] Second accommodation grooves are provided on the circumferential side walls of the transfer disk 21 and the flipping disk 22, and the second accommodation grooves are arranged along the circumferential direction. The wire loop 7 is semi - circular, and two wire loops 7 are respectively embedded in the second accommodation grooves of the transfer disk 21 and the flipping disk 22.

[0079] A first card slot 31 is provided at the middle position of the crochet hook 3, and an opening slot 32 is provided at the bottom position of the crochet hook 3. The crochet hook 3 is arranged in the first accommodation groove of the transfer and flipping disk 2, and the wire loop 7 is embedded in the first card slot 31 of the crochet hook 3. The crochet hook 3 can rotate around the wire loop 7. When the bottom end of the crochet hook 3 rotates inwards, the opening slot 32 of the crochet hook 3 is for the insertion of the sock loop to hook the sock on the hosiery machine.

[0080] The presser needle 4 is provided with a guide groove 41, and the guide groove 41 is arranged vertically. The presser needle 4 is arranged in the first accommodation groove of the transfer and flipping disk 2, and the wire loop 7 is embedded in the guide groove 41 of the presser needle 4. The presser needle 4 can move up and down along the wire loop 7. When the presser needle 4 moves downwards, it closes the opening slot 32 of the crochet hook 3 to control the sock. When the presser needle 4 moves upwards, the opening slot 32 of the crochet hook 3 is opened, and when the bottom end of the crochet hook 3 rotates outwards, the sock is released.

[0081] Furthermore, for the seam head transfer device for an open - toe hosiery machine in this embodiment, a locking projection 42 is provided at the bottom end of the presser needle 4.

[0082] A locking card slot 33 is provided at the bottom end of the crochet hook 3, and an arc - shaped convex block 34 is provided at the top end of the locking card slot 33 of the crochet hook 3.

[0083] When the presser needle 4 moves downwards, the locking projection 42 of the presser needle 4 is inserted into the locking card slot 33 of the crochet hook 3, and the arc - shaped convex block 34 of the crochet hook 3 cooperates with the locking projection 42 of the presser needle 4. The arc - shaped convex block 34 locks the locking projection 42 of the presser needle 4 to prevent the presser needle 4 from moving upwards.

[0084] Optionally, as Figure 4 and Figure 8 shown, for the seam head transfer device for an open - toe hosiery machine in this embodiment, the crochet hook driving mechanism 5 includes: a first air cylinder 51 and a crochet hook push block 52.

[0085] The first air cylinder 51 is arranged on the frame 1, the crochet hook push block 52 is arranged on the first air cylinder 51, and the crochet hook push block 52 is connected to the movable rod of the first air cylinder 51.

[0086] There are two crochet pushing blocks 52, namely: an upper pushing block 521 and a lower pushing block 522. The upper pushing block 521 and the lower pushing block 522 are respectively arranged on the first air cylinder 51, connected to the movable rod of the first air cylinder 51, located outside the crochet hook 3 (transfer and flip disc), and the upper pushing block 521 and the lower pushing block 522 are respectively located below and below the wire loop 7.

[0087] The crochet hook 3 is arranged in the first accommodating groove of the transfer and flip disc 2, and one end of the crochet hook 3 protrudes from the side wall of the transfer and flip disc 2. The movable rod of the first air cylinder 51 drives the upper pushing block 521 and the lower pushing block 522 to alternately extend and retract. When the upper pushing block 521 and / or the lower pushing block 522 extends, it pushes the part of the crochet hook 3 that protrudes from the transfer and flip disc 2, causing the crochet hook 3 to rotate around the wire loop 7.

[0088] In this embodiment, the driving motor drives the transfer and flip disc 2 to rotate. When the first air cylinder 51 drives the lower pushing block 522 to extend (at this time the upper pushing block retracts), the crochet hooks 3 on the transfer and flip disc 2 sequentially pass by the lower pushing block 522. The lower pushing block 522 pushes the bottom end of the crochet hook 3, and the crochet hook 3 rotates around the wire loop 7, causing the opening slot 32 at the bottom end of the crochet hook 3 to approach the sock until the sock on the sock machine is hooked; when the first air cylinder 51 drives the upper pushing block 521 to extend (at this time the lower pushing block retracts), the crochet hooks 3 on the transfer and flip disc 2 sequentially pass by the upper pushing block 521. The upper pushing block 521 pushes the top end of the crochet hook 3, causing the crochet hook 3 to rotate in the reverse direction around the wire loop 7, making the opening slot 32 at the bottom end of the crochet hook 3 move outward, and the crochet hook 3 resets and releases the sock.

[0089] Furthermore, in the seam transfer device for an open - toe sock machine in this embodiment, the upper pushing block 521 and the lower pushing block 522 have the same structure, both being in an L - shape at a right angle. The upper pushing block 521 and the lower pushing block 522 both include: a connecting rod 5201 and a push rod 5202.

[0090] The connecting rod 5201 is connected to the movable rod of the first air cylinder 51. The side surface of the push rod 5202 includes an inclined surface section 52021 and a flat surface section 52022, and the inclined surface section 52021 and the flat surface section 52022 are connected.

[0091] In this embodiment, when the crochet pushing block 52 extends, the crochet hook 3 abuts against the inclined surface section 52021 of the push rod 5202, and the crochet hook 3 slides along the inclined surface section 52021 to the flat surface section 52022 of the push rod 5202, thereby pushing the crochet hook 3 and causing the crochet hook 3 to rotate around the wire loop 7.

[0092] Furthermore, in the seam transfer device for an open - toe sock machine in this embodiment, the first air cylinder 51 is provided with two first sliding grooves 511. The connecting rods 5201 of the upper pushing block 521 and the lower pushing block 522 are slidably arranged in the two first sliding grooves 511 of the first air cylinder 51 and are connected to the movable rod of the first air cylinder 51 through a connecting column 5203.

[0093] Optionally, as Figure 2 and Figure 9 shown, in this embodiment, for the seam head transfer device of an open - toe sock knitting machine, the press - needle driving mechanism 6 includes: a second air cylinder 61 and a press - needle pushing block 62.

[0094] The second air cylinder 61 is arranged on the frame 1, and the press - needle pushing block 62 is arranged on the second air cylinder 61 and connected to the movable rod of the second air cylinder 61. The second air cylinder 61 is used to drive the press - needle pushing block 62 to move up and down.

[0095] The top end of the press - needle 4 is provided with a protruding part 401.

[0096] The press - needle pushing block 62 is provided with a limiting groove 621. The limiting groove 621 of the press - needle pushing block 62 is used for the protruding part 401 of the press - needle 4 to be inserted, so that when the press - needle pushing block 62 moves up and down, it drives the press - needle 4 to move up and down.

[0097] In this embodiment, the driving motor drives the transfer and turning disk to rotate, so that the protruding parts of the press - needles sequentially pass through the limiting grooves of the press - needle pushing blocks. After the second air cylinder drives the press - needle pushing block to move up and down, when the press - needles on the transfer and turning disk pass through the limiting grooves of the press - needle pushing blocks, the press - needle pushing blocks drive the press - needles to move up and down in sequence. When the press - needles descend, they press the socks against the hook - needles; when the press - needles rise, they release the socks pressed against the hook - needles.

[0105] The present invention also provides a method for using a seam transfer device for an open - toe sock knitting machine

[0106] For the seam transfer device for an open - toe sock knitting machine in this embodiment, its working process is as follows

[0107] S1 Move the transfer and flip disc to directly above the sock knitting machine cylinder, and insert the crochet hook between adjacent sock needles of the sock knitting machine

[0108] After the sock 810 on the sock knitting machine is knitted, the frame 1 drives the transfer and flip disc 2 to rotate, moving the transfer and flip disc equipped with the same number of crochet hooks and press needles as the sock needles to directly above the sock knitting machine cylinder 830. The transfer and flip disc is concentric with the cylinder 830. Then, all the sock needles 820 on the sock knitting machine carry the sock 810 to rise to a certain height, so that each crochet hook 3 is inserted between two adjacent sock needles 820, obtaining the state as shown in Figure 11 the figure

[0109] S2 The crochet hook driving mechanism drives the crochet hook to rotate to hook the sock needle, and the press needle driving mechanism drives the press needle to move to lock the sock

[0110] When the crochet hook 3 and the sock needle 820 reach an appropriate height difference, the first cylinder drives the lower push block to extend. The lower push block pushes the bottom end of the crochet hook to rotate towards the center of the circle, that is, the opening groove of the crochet hook approaches the seam coil of the sock until the sock is completely hooked. After the crochet hook completely hooks the sock, the second cylinder drives the press needle push block to move downward. The press needle push block drives the press needle 4 to move downward to block the opening groove of the crochet hook, so that the sock 810 is controlled by each crochet hook 3 and press needle 4. The sock knitting machine cylinder and the transfer and flip disc rotate synchronously, and the sock coil is disengaged from the sock needle through the loop - dropping knife and the press - knife and transferred to the transfer and flip disc, realizing the transfer of the sock from the sock knitting machine cylinder to the transfer and flip disc, obtaining the state as shown in Figure 12 the figure

[0111] S3 The flip disc flips 180 degrees

[0112] The flipping disk 22 flips 180 degrees along the position of the rotation axis. Since the crochet hook 3 and the pressing needle 4 firmly hold the sock, when the flipping disk 22 flips, half of the coils on the sole of the sock will approach half of the coils on the instep along with the flipping disk. Until reaching the 180-degree position, half of the coils on the sole of the sock and half of the coils on the instep are vertically and oppositely attached to each other, obtaining as Figure 13 the state shown.

[0113] S4 causes the transfer flipping disk to move to the sewing machine to sew the sock.

[0114] The frame drives the transfer flipping disk to rotate, and moves the transfer flipping disk with the sock to the sewing machine 840, obtaining as Figure 14 the state shown.

[0115] Finally, the sewing machine 840 moves forward close to the intersection point of the upper and lower crochet hooks, and the instep coils and the sole coils can be knitted together through the sewing needle to complete the sock sewing operation.

[0116] In the present invention, unless otherwise clearly specified and limited, the first feature being "on" or "under" the second feature may be that the first feature is in direct contact with the second feature, or the first feature and the second feature are indirectly in contact through an intermediate medium.

[0117] Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature is at a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature is at a lower horizontal height than the second feature.
