Description

Technical Field

[0001] The present invention belongs to the technical field of knitting machinery, and relates to a hosiery knitting machine, and more specifically to a picking device and a picking method for removing and holding the finished product from the hosiery knitting machine after the hosiery knitting is completed. Background Art

[0002] The current development trend in hosiery machines is toward integrated knitting and sewing, meaning that the toe-stitching process is automatically completed after knitting is complete. To achieve this, the finished product, or sock, must be removed from the knitting unit and transferred to the toe-stitching unit. The device that completes this process is called a pickup device. When the socks are finished, they are attached to the needles of the needle cylinder using the final row of coils, with each coil corresponding to the needle. To complete the subsequent toe-stitching, the regularity of each coil must be maintained so that subsequent operations can be performed on each coil. Therefore, the coils must not be disrupted, and each coil must be individually retained. This presents a major challenge in the design of a pickup device.

[0003] CN101970739A discloses a picking device that can achieve the above-mentioned purpose, which includes an annular picking body, the annular picking body (11) supports picking members (29), the picking members (29) can slide radially relative to the picking body (11), the picking body (11) can be coaxially arranged around the needle cylinder (121) of a circular knitting machine (100) for hosiery or the like, so that each of the picking members (29) faces laterally towards the needle (123) of the machine (100); an actuating device, the actuating device is arranged to act on the picking members (29) to move the picking members towards or away from the axis (11a) of the picking body (11), so that each picking member (29) is engaged with or disengaged from the needle (123) of the machine (100) it faces, each of the picking members (29) is suitable for picking up the needles (123) held in the picking body. knitted loops on the needle (123); each of the picking members (29) has a seat (30) at the end (29a) facing the axis (11a) of the picking body (11), and the seat (30) can be arranged with the needle rod (123b) of the needle (123) close to the area of ​​the needle tongue (123d) of the needle (123) on the opposite side of the needle head (123c) of the needle (123), and the actuating device includes an elastic device (33) and a radial pushing member (34), the elastic device (33) acts on the picking member (29) to make the picking member slide toward the axis (11a) of the picking body (11), and the radial pushing member (34) acts on the picking member (29) to make the picking member slide away from the axis (11a) of the picking body (11) against the action of the elastic device (33).

[0004] In this technical solution, the pick-up element is perpendicular to the knitting needles. From a spatial perspective, the needles are vertical and the pick-up element is horizontal. To complete the subsequent toe-sewing operation, the pick-up device must transfer the knitted socks back to the toe-sewing device. This obviously increases the overall cost of the machine while also reducing its efficiency.

[0005] CN105887322A discloses another picking device, which includes: a fixed seat frame; a fixed half-tooth frame, which is fixed to the bottom of the fixed seat frame and has at least one first functional tooth on it; a flip half-tooth frame, which is radially opposite to the fixed half-tooth frame and rotatably connected to the fixed seat frame, and has at least one second functional tooth on it, and the outer surface of the second functional tooth has a sewing needle groove, and the flip half-tooth frame can be flipped relative to the fixed half-tooth frame to align the first functional tooth and the second functional tooth; a fixed half-tooth frame coil transfer assembly, which is connected to the fixed seat frame and the fixed half-tooth frame, and is used to transfer the coil on the first functional tooth to the second functional tooth after the first functional tooth and the second functional tooth are aligned; and a flip half-tooth frame coil release assembly, which is connected to the fixed seat frame and the flip half-tooth frame, and is used to release the coil from the second functional tooth after the sock toe is sewn.

[0006] The fixed half tooth rack and the flip half tooth rack of this technical solution are used as both a picking device and a part of the seam head device, which reduces the number of stitch transfers. Its disadvantage is that its first and second functional teeth are parallel to the knitting needles, and in fact, they are 180 degrees apart from the knitting needles when completing the picking action. 0 Angle; after it picks up the coil and holds the coil until the beginning of sewing, there is a short period of time when the coil is not supported by anything and can only rely on the external negative pressure air source to provide suction to hold the coil. However, this suction is not reliable and the coil may still slide down under the action of the sock's gravity and thus fall off the functional teeth.

[0007] CN1723308A discloses another method and device for connecting the edges of tubular knitted fabrics. This technical solution is the closest prior art to the present invention, which includes a movable bracket (300) that can be connected to the needle bed (100) of the circular knitting machine and can be moved from the needle bed (100) and the closing station and / or the hooking station (400). The bracket (300) supports a device (25, 26) for removing the stitches of the last knitted row. The device (25, 26) includes a device (26) for removing one half row, that is, half of the stitches of the last knitted row, and a device (25) for removing the other half row. The movable bracket (300) is provided with a driving device (22, 23) and a transfer device (28) that can move the stitches of one half row to the device (26) for removing the stitches of the other half row. For the uncited parts of this prior art, please refer to its original text.

[0008] The disadvantage of this technical solution is that its crown (13) and ring (15) require a large volume to complete the installation and driving operations, including a large diameter and thickness. The large thickness means that when it is used with a hosiery machine, the top cover of the hosiery machine must be tilted at a large angle to have enough space to accommodate the pickup device, which requires increasing the structural strength of the hosiery machine and increases the difficulty of arranging the parts on the hosiery machine. The large diameter makes the pickup device unable to be directly used as a sewing workstation. Even after moving the coils of one half row to the device that removes the other half row, the coils still need to be moved to other parts again before sewing can be performed; that is, the pickup device cannot be used as a sewing base station at the same time. Summary of the Invention

[0009] The object of the present invention is to provide a picking device for removing and holding a finished knitted product from a hosiery machine, which can reliably hold the finished knitted product and conveniently perform a seaming operation.

[0010] Another object of the present invention is to provide the aforementioned picking method.

[0011] To this end, the technical solution adopted by the present invention is as follows: a picking device for removing and holding the finished product from the hosiery machine comprises a fixed half-tooth rack and a flip half-tooth rack, the flip half-tooth rack can be radially rotated 180 degrees 0 The two gear racks are flipped so that they can have two states: flat as a complete ring and stacked as two half rings; a plurality of transfer teeth are indirectly mounted on the fixed half gear rack and the flip half gear rack, and when the two half gear racks are stacked, all the transfer teeth are opposite to each other; the characteristics are:

[0012] The fixed half-tooth rack and the flip half-tooth rack are both axially mounted with an upper half-ring and a lower half-ring. The upper half-ring and the lower half-ring can be flattened into a complete upper ring and a lower ring with the movement of the flip half-tooth rack, or can be folded into axially stacked half-rings. The upper ring and the lower ring can be driven by the first driving mechanism to perform axial relative displacement. The transfer teeth are mounted on the outer circumference of the upper ring and extend to the outer circumference of the lower ring.

[0013] The inner wall of the lower ring has a circumferential circular groove, and the outer wall of the lower ring has a plurality of axial hook grooves extending to the bottom surface of the lower ring;

[0014] The transfer hook is frame-shaped and has one longitudinal side and two transverse sides, one transverse side being a driving portion, and the other transverse side and the longitudinal side forming an L-shaped line-catching portion, wherein the connection between the driving portion and the line-catching portion is a transfer hook shaft; the transfer hook is installed in the lower ring, the transfer hook shaft is placed in the circumferential groove, the driving portion faces the center of the lower ring, and the line-catching portion extends out of the line-catching groove;

[0015] It also includes a second driving mechanism, which extends into the lower ring from above and drives the driving part of the transfer hook to move up and down.

[0016] A plurality of guide grooves are also provided on the outer circumference of the lower ring, which are arranged one by one with the hooking grooves; the positions of the guide grooves coincide with the extension lines of the transfer teeth.

[0017] The front end of the transfer tooth has an inner groove facing the center of the lower ring, which matches the knitting needle head; the middle part of the transfer tooth has an outer groove facing the opposite direction of the center of the lower ring.

[0018] To facilitate assembly, the lower ring is composed of a main body and a bottom cover. The main body and the bottom cover each have a circumferential arc groove, which form an open circumferential circular groove after being combined.

[0019] The second driving mechanism is an annular pressure block, which is arranged in the lower ring and fixed to the driving part of the transfer hook. The annular pressure block extends out of the lower ring through a connecting rod.

[0020] In order to achieve the second purpose of the invention, the technical solution adopted is as follows:

[0021] A method for removing and holding finished knitted goods from a hosiery machine employs the aforementioned device. When the socks are knitted, the picking device is moved as a whole to the top of the needle cylinder of the hosiery machine, so that the transfer teeth, the guide groove, and the knitting needles of the needle cylinder are aligned one by one and in the same straight line. The front end of the transfer teeth engages with the needle heads of the knitting needles. At this point, the last row of stitches of the socks is hooked on the needle heads of the knitting needles, and the fixed half-tooth rack and the flip half-tooth rack form a complete ring shape, with both the upper ring and the lower ring forming a complete ring shape.

[0022] The second driving mechanism drives the driving part of the transfer hook, causing the transfer hook to rotate around the transfer hook axis, and the thread hook portion of the transfer hook swings relative to the axial direction of the lower ring, so that the thread hook portion forms a large angle with the axial direction; at the same time, the first driving mechanism drives the lower ring to descend to a position below the coil on the knitting needle;

[0023] The second driving mechanism drives the driving portion of the transfer hook in the reverse direction, causing the transfer hook to rotate in the reverse direction around the transfer hook axis, so that the wire hook portion forms a small angle with the axial direction or is parallel to the axial direction, thereby holding the coil from below;

[0024] The pick-up device rises and moves to the set position as a whole, taking away the knitted socks. During this process, on the one hand, the transfer teeth pass through the coil, and on the other hand, the hook part of the transfer hook grips the outside of the coil to hold the coil.

[0025] When it moves to the set position, push the suspended socks to the top of the picking device and flip the half gear rack 180 degrees. 0At this time, for the flipped half gear rack, the positions of the upper and lower rings are reversed. For the sake of convenience, they are still referred to as the upper ring and the lower ring according to their original state. At this time, the transfer teeth of the two half gear racks correspond one to one.

[0026] The second drive mechanism of the fixed half-tooth rack drives the transfer hook, causing its wire hook portion to open and no longer contact the coil. Simultaneously, the first drive mechanism of the fixed half-tooth rack drives the lower ring downward, pushing the coil on the transfer tooth of the fixed half-tooth rack downward and transferring it to the corresponding transfer tooth of the flip half-tooth rack. In other words, each transfer tooth of the flip half-tooth rack is threaded with two coils. At this time, the transfer hook of the flip half-tooth rack still holds the coil.

[0027] Since the state of having reached two coils being threaded on one transfer tooth has been reached, the available seaming device can now be used for stitching. The seaming device is prior art.

[0028] After the socks are sewn, they are hung on the flip half-tooth frame. After the flip half-tooth frame is turned back to the horizontal state, the transfer hook is released by the second driving mechanism of the flip half-tooth frame, and is pushed by the first driving mechanism of the flip half-tooth frame to remove the socks, completing the whole process.

[0029] As can be seen from the above description, in the present invention, during the process of transferring the coil from the knitting needle to the transfer tooth and thereby removing the sock and transferring it to another location, the coil is sheathed on the transfer tooth. At the same time, outside the coil, specifically below the coil, there is a transfer hook with a hooking portion that supports the coil so that the coil will not fall due to the gravity of the sock. In addition, the transfer hooks and transfer teeth are densely arranged on the outer circumference of the lower ring. If the number of knitting needles is N, then there are N transfer hooks and transfer teeth, that is, a total of 2N parts are arranged on the outer circumference. This makes the distance between adjacent transfer hooks and transfer teeth very small. The coil is actually stuck between the transfer hook and the transfer tooth, and the coil can be kept from falling by friction alone.

[0030] During the flipping process of the half-rack, the wire-engaging portion of the transfer hook always holds the coil on the half-rack, providing friction. The wire-engaging portion and the transfer teeth form a closed geometric shape, ensuring support for the coil regardless of the angle of the flip. For the coil on the fixed half-rack, the wire-engaging portion of the transfer hook holds the coil until it is fully flipped. Once fully flipped, the transfer teeth of the two half-racks align, eliminating the need for support from the wire-engaging portion.

[0031] It can be seen that the present invention can complete the seam end directly on the pick-up device while always reliably keeping the finished product. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] See the accompanying drawings. The device of the present invention comprises a gear rack 1, an upper ring 2, a lower ring 3, and an annular pressure block 4, wherein the lower ring 3 is composed of a main body 31 and a bottom cover 32 fixed thereto; the above-mentioned annular components are divided into two semi-rings, for example, the gear rack 1 is composed of a flipping half-gear rack 1a and a fixed half-gear rack 1b, and the flipping half-gear rack can be radially flipped with the pin hole 11 as the axis to form a complete ring or a stacked half-ring with the fixed half-gear rack. The specific installation method and flipping method of the half-gear rack are prior art, and many references mentioned in the background technology section have also described them, so they will not be repeated here.

[0043] The other annular components mentioned above are divided into two half-rings, which are respectively installed on the two half-tooth racks. Those installed on the flip half-tooth rack and flip with it are denoted by the suffix a; those installed on the fixed half-tooth rack and fixed are denoted by the suffix b.

[0044] The outer surface of the upper ring 2 is provided with a plurality of axial grooves 21. This embodiment is designed for a 200-needle hosiery machine, so the number of axial grooves 21 is 200, evenly distributed over 360 degrees. 0 on the circumference.

[0045] See also Figure 5 , Figure 6 For the convenience of processing and installation, the lower ring is divided into a main body 31 and a bottom cover 32. Figure 4 Figure 5 Observing from the side below, it can be seen that the outer circumferential surface of the main body 31 has a plurality of axial grooves 311, and the circumferential side surface of the bottom cover 32 also has axial grooves 321. There are 200 grooves 311 and 321, each corresponding one-to-one with the grooves 21, forming an axially continuous groove. The grooves 311 and 321 are collectively referred to as guide grooves.

[0046] On the lower portion of the outer circumferential surface of the main body 31, a transfer groove 312 is located between every two adjacent guide grooves 311. On the circumferential side of the bottom cover 32, a transfer groove 322 is located between every two adjacent guide grooves 321, extending to the bottom surface of the bottom cover 32. These grooves 312 and 322 also correspond one-to-one and are collectively referred to as transfer grooves. There are also 200 of these grooves.

[0047] The inner wall of the main body 31 features a circumferential groove 313 with an arcuate cross-section. The inner wall of the bottom cover 32 also features a circumferential groove 323 with an arcuate cross-section. When the main body and bottom cover are assembled and fixed, a complete circumferential groove is formed; it can be roughly imagined as an annular groove for accommodating a sealing ring. The wall of circumferential groove 313 also features a straight groove 314, perpendicular to the circumference, located in the same position as the transfer hook groove. The bottom cover also has a straight groove, but this cannot be seen due to the angle.

[0048] A connecting rod 35 is provided above the main body, which can be connected to a mechanism such as a piston or a motor to drive the lower ring 3 to move up and down. The connecting rod 35 is called the first driving mechanism.

[0049] See also Figure 7 . The annular pressure block 4 is also provided with a connecting rod 45 on the top, which can be connected to a piston or a motor and other mechanisms to drive the annular pressure block 4 to move up and down. The annular pressure block 4 is called a second driving mechanism. The annular pressure block in this embodiment is processed into two parts and stacked and fixed. As shown in the figure, the 4a\4b on the left is flipped over and assembled with the 4a\4b on the right to obtain a complete annular pressure block. The side of the annular pressure block has a groove 41 extending inward, which can be used to accommodate other components.

[0050] See also Figure 8 The transfer teeth 7 include a root portion 71, which is fixed to the circumferential surface of the upper ring 2. In this embodiment, there are 200 transfer teeth, which are retained in the groove 21 of the upper ring and can extend into the guide grooves 311 and 321. The head 72 of the transfer tooth has an inner groove that opens inward, toward the center of the entire device; the back of the tooth also has an outer groove 73, which faces away from the center.

[0051] See also Figure 9 The transfer hook comprises a transfer hook shaft 81, a driving portion 82 and a line hooking portion 83, which are fixed as a sheet-like whole. The line hooking portion is L-shaped, and the thickness of the transfer hook shaft 81 is greater than that of the driving portion and the line hooking portion.

[0052] The transfer hook is installed in the lower ring 3. Specifically, the transfer hook shaft 81 is positioned within the circumferential grooves 313 and 323. Its shape matches the grooves, allowing for rotation parallel to the device's radial direction. Furthermore, because the circumferential grooves also contain straight grooves 314, the transfer hook shaft 81 fits within these grooves, preventing circumferential displacement. The hook's hooking portion 83 extends from the hook's grooves 312 and 322. The hook's driving portion 82 extends into the groove 41 of the annular pressure block. As the annular pressure block 4 moves up and down relative to the lower ring 3, the hook rotates about the hook shaft 81, thereby changing the angle of its hooking portion 83.

[0053] See also Figures 10 to 12 This set of drawings focuses on the positional relationship between the upper ring, the lower ring, and the annular pressing block. Figure 10 In the state, the upper ring 2 and the lower ring 3 are in a close state, and the annular pressure block 4 is also in a higher position. Figure 11 Relative to Figure 10 For example, the lower ring 3 moves downward under the action of the first driving mechanism, and it can be seen that there is a large distance between the upper ring and the lower ring. Figure 12 Relative to Figure 11 For example, the annular pressing block 4 (ie, the second driving mechanism) moves downward, and the annular pressing block 4 moves from slightly above the circumferential groove 313 to below the circumferential groove 313 .

[0054] See also Figure 13 . This set of figures briefly shows the process of picking up socks. It should be pointed out that in the figures, the transfer teeth 7 and the knitting needles 9 are on the same plane, while the transfer hook 8 is between the two transfer teeth, that is, the transfer hook 8 is not on the same paper surface of the transfer teeth 7 and the knitting needles 9. When the hosiery machine completes knitting, the knitted socks are hung on the knitting needles 9 through the last row of coils 00. At this time, the picking device of this embodiment is moved to the top of the needle cylinder and aligned according to the set zero position so that the transfer teeth 7, guide grooves 311, 321, and knitting needles 9 are aligned one by one and are all on the same straight line; press the annular pressure block 4 downward to open the transfer hook 8, and at the same time lower the picking device as a whole so that the head 72 of the transfer tooth 7 and the head of the knitting needle 9 are in contact and matched, that is Figure 13 The transfer hook 8 continues to be in the open state, and the lower ring 3 is lowered by the connecting rod 35. At this time, the guide grooves 311, 321 and the knitting needle 9 slide relative to each other and thereby maintain the same position until the transfer hook 8 is lower than the coil 00, that is, Figure 13 b; pull the annular pressure block 4 upward to rotate the transfer hook 8 in the opposite direction back to the closed state, at this time the hook line portion is below the coil 00, which can provide support, ie Figure 13 transfer hook 8 continues to maintain a closed state, the lower ring 3 rises through the connecting rod 35, at this time the hook line portion of the transfer hook drives the coil 00, the coil 00 is pulled onto the transfer tooth 7, ie Figure 13 The state shown in d: the picking device rises and moves as a whole, taking the socks out of the needle cylinder.

[0055] The above description has actually been completed and removed from the hosiery machine and kept the picking process of the finished product. For completing final stitching, the present embodiment also proceeds to the following steps.

[0056] After the picking device moves to the set position with the knitted socks, the suspended socks are pushed above the picking device. This is a common technical method in the field and will not be described here. Then the turning half gear rack 1a together with all the semi-annular parts installed thereon are turned 180 degrees. 0 At this time, the transfer teeth 7 of the two half gear racks correspond one to one and the heads are opposite.

[0057] The semi-annular pressure block 4b of the fixed half rack drives half of the transfer hook 8, causing its hooking portion 83 to open and no longer contact the coil. Simultaneously, the connecting rod 35 of the fixed half rack drives the lower half ring 3b downward, thereby pushing the coil on the transfer tooth of the fixed half rack downward and transferring it to the other half of the corresponding transfer tooth of the flip half rack. In other words, each transfer tooth of the flip half rack is threaded with two coils. At this time, the transfer hook of the flip half rack still holds the coil.

[0058] Owing to have reached the state that two coils are worn on a transfer tooth, available seam head device can be sewed up this moment.Seam head device is prior art, does not repeat them.The outer groove 73 on the transfer tooth makes it easier to meet.

[0059] After the socks are sewn, they are hung on the flip half-tooth frame. After the flip half-tooth frame is turned back to the horizontal state, the transfer hook is opened with the semi-annular pressing block 4a of the flip half-tooth frame, and the connecting rod 35 of the flip half-tooth frame is used to push the lower half ring 3a to remove the socks, completing the whole process.
