Description

Mechanism for transferring loop from knitting needle of knitting machine and sewing station mechanism

Technical Field

The present invention relates to an improvement of the mechanism described in patent No. EP2377979, and more particularly to a mechanism for ensuring the transfer of a textile material, such as a sock, from the needles after it has been knitted in a knitting machine, and to a mechanism for a station for stitching the open ends of the textile material.

Background

Tubular textiles such as socks are produced by warp knitting in a circular knitting machine. The end of the fabric article having the open ends is then removed from the needles of the circular knitting machine and brought to a toe sewing station where it is sewn. The transfer of the tubular textile article from the circular knitting machine to the toe sewing station can be carried out by an automatic mechanism, for example as described in patent No. EP 2377979.

As described in patent EP2377979, when the hosiery knitting procedure in the knitting machine is completed, the last row of knitting needle loops is removed one by one from the knitting needles by means of the transfer member and the blade member and transferred to a toe-stitching station knitting needle, which is remote from the knitting needle position.

The transfer element described in patent No. EP2377979 (as shown in fig. 31 to 38 thereof) comprises a front opening 1e and into which the hook of the knitting needle is inserted before the transfer of the loop. To ensure that this is possible, the front opening should comprise a certain width, otherwise the hook of the knitting needle cannot be inserted into the transfer element. Such a construction requires a more precise control of the positioning between the transfer element and the needles, which, however, has certain drawbacks, such as the need to use a thicker transfer element to intensify the effort in moving the heavy objects, thus increasing the costs. Furthermore, the transfer element described in patent No. EP2377979 comprises a material filling at the most distal end for attaching the hook of the knitting needle, such a complex geometry being difficult and expensive to produce.

On the other hand, the transfer of the loops by the transfer element to the toe sewing station has mainly a circular configuration, half of which can be turned 180 degrees to open and close with respect to the other half. One semicircle comprises a plurality of female teeth that project along the semicircle, while the other semicircle comprises the same number of male teeth as the female teeth, which project along this semicircle in the same manner.

When one semicircle is closed relative to the other, structural correspondence is ensured between the male and female teeth. In the next step, where one half circle is closed over the other half circle, the loops in one half circle will be adjacent to the loops in the other half circle, so that the loops can be sewn and the ends of the textile material can be sewn.

As disclosed in the above-identified applications, the half circle carrying the female tooth may be closed (and opened) on the half circle carrying the male tooth, and the coil on the female tooth may be adjacent to the coil in the male tooth. Thus, when the coils that are close to each other are located on the male tooth, the toe sewing procedure, i.e. the sewing procedure, is performed. Thus, the male teeth should have a specific structure. The sewing needle should be very close to the pair of stitches close to each other, otherwise, sewing cannot be performed during the sewing process in which the stitches are close. In summary, the male tooth should have running clearance while carrying the thread pairs, so that the needle can enter and leave each thread pair, for which clearance can be the configuration of the U-shaped or V-shaped channel in EP2377979 (as shown in fig. 30 thereof). However, these prior art structures sometimes prevent the needle from finding the proper running clearance and may result in the seam being incorrectly formed or even breaking the sewing needle, for example, when the pair of stitches is stretched in opposition. Fig. 30 is a plan view showing the V-shaped channel structure 515b, the stitches 73, and the sewing needle 80 according to the related art.

In practice the toe stitching procedure (stitching procedure) is performed on the male teeth, but in theory the semi-circle carrying each male tooth could also be closed on the semi-circle carrying each female tooth, while each female tooth could be provided in a U and V configuration, for example, for stitching as described above. In general, the teething configuration of the stitch pair that is sewn (i.e., the toe sewing procedure) includes, for example, a U-shaped or V-shaped configuration.

Detailed Description

The technical solution in the embodiments of the present invention is clearly and completely described below with reference to the drawings in the embodiments of the present invention. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those specifically described and will be readily apparent to those of ordinary skill in the art without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

The present invention relates to a mechanism for ensuring the transfer, and more particularly to a mechanism for transferring a sock from a knitting machine to a toe sewing station.

As described in patent No. EP2377979, when the knitting procedure of the sock is completed in the sock making machine, the toe of the sock is open and the last stitch 73 on the toe is still on the needle 10 of the knitting machine. The toe of the sock, as described in patent No. EP2377979, can be sewn using a different number of lamellar elements 31 and transfer elements 41. The components are positioned opposite each other on either side of the same face of the chuck (not shown).

As shown in fig. 1 to 8 and 16, the procedure is shown how the last loop 73 still on the needle 10 is removed in steps by the blade element 31 and the transfer element 41. (see the description of the steps of the above procedure in the application document of patent number EP 2377979). That is, the transfer element 41 is brought close to the hook 11 of the knitting needle 10 by pushing of the transfer drive end 43 and by pushing again of the peeling drive end 33, the blade element 31 first catches the top of the loop 73 and then moves downwards unhooking it from the latch 12 of the knitting needle 10.

In the present invention, each transfer element 41 at least partially grips an outer surface of the hook 11 of each needle, and each transfer element 41 comprises the transfer end 42, the transfer end 42 being maintained between the body of the needle 10 and the hook 11 when the latch 12 is closed to transfer the loop 73.

The bottom of the transfer member 41 includes an arcuate structure that conforms to the shape of the outer surface of the hook 11 and grips onto the outer surface of the hook 11 so as to preferably cover the outer surface of the hook 11 when the transfer member 41 is brought into close proximity to the hook 11 to transfer the loop 73. The above-mentioned arc at the bottom of each transfer element 41 preferably covers mainly the top and outer front surface area of each hook 11.

The transfer end 42 of the transfer member 41 is located in front of the hook 11 and covers the trailing end of the hook 11 from the outside, whereby the transfer end 42 is maintained at a position slightly lower than the open end of the hook 11 when the transfer member 41 is brought close to the hook 11 to perform the transfer of the stitch 73.

Preferably, as shown in fig. 17, the transfer end 42 of the transfer element 41 may comprise a curved structure towards the body of the needle 10. In this way, when the latch 12 of the needle 10 is closed in the next step, the loop 73 can be transferred in a relatively safe manner.

As shown in fig. 3 and 4, the blade member 31 slightly returns in the radial direction and moves downward after the loop 73 is unhooked from the latch 12 by moving the loop 73 downward by the pressure applied from the peeling end 32; in the next step, as shown in fig. 5, it moves forward and grabs the coil 73 from the bottom; in the next step, as shown in fig. 6, it moves the coil 73 upwards and at the same time the latch 12 is closed. In this case, the transfer end 42 is maintained between the hook 11 and the latch 12. As shown in fig. 7, when the sheet member 31 moves further upward, the coil 73 is transferred to the corresponding transfer member 41.

In the next step, as shown in fig. 8, the transfer member 41 is moved together with the blade member 31 away from the knitting needle 10 to the sewing station corresponding to the toe sewing procedure, i.e. below the jaw unit 50.

As shown in fig. 18 to 22, after the transfer member 41 and the sheet member 31 are positioned below the jaw unit 50, they move up and are fitted to the first and second longitudinal teeth spaced around the jaw unit 50 by 360 degrees, the first longitudinal tooth of the present embodiment being a male tooth 511 and the second longitudinal tooth being a female tooth 521. The male tooth 511 is fastened to the corresponding jaw by means of its inwardly extending male fixing portion 512, while the female tooth 521 is fastened to the corresponding jaw in the same way by means of its inwardly extending female fixing portion 522.

As shown in fig. 9 to 14, the steps of transferring the coil 73 to a male tooth 511 are shown. Each transfer element 41 comprises a transfer low-profile body 45, which projects slightly and extends perpendicularly from the body, and which comprises a transfer channel 44 shaped like a U. When the transfer member 41 moves upward together with the sheet member 31, the male and

female teeth

511, 521 are inserted into the respective transfer channels 44, and the coil 73 is released to the male extension 513 of the male tooth 511 and the female extension 523 of the female tooth 521. Then, the transfer member 41 and the blade member 31 move upward away from the respective male and

female teeth

511, 521. As shown in fig. 14A, the male tooth 511 has a male end 515 and the female tooth 521 has an end slot 524.

As shown in fig. 28, each transfer element 41 comprises a plate 46, the transfer low-bottom body 45 being at the bottom of the plate 46 and slightly protruding. The transfer low-bottom body 45 has a transfer channel 44, which includes a first side plate 451, a second side plate 452, and a connecting plate 453, wherein the first side plate 451 and the second side plate 452 are parallel to each other and are spaced apart from each other, and two sides of the connecting plate 453 are connected to the first side plate 451 and the second side plate 452, respectively. In this embodiment, an end of the first side plate 451, which is away from the plate 46, includes a first inclined surface portion 454, the second side plate 452 includes a second inclined surface portion 455 corresponding to the first inclined surface portion 454, the first inclined surface portion 454 and the second inclined surface portion 455 are respectively inclined toward the rear and the lower direction at one side of the transfer passage 44, and the first inclined surface portion 454 and the second inclined surface portion 455 have symmetrical shapes. The first and

second ramp portions

454 and 455 constitute a part of the arc shape of the bottom of the transfer member 41, and cover the outer surface of the hook 11 in cooperation with the curved structure of the transfer tip 42.

The plate 46 includes a transfer driving end 43, and has a body 461 and an extension 462, the transfer driving end 43 extends upward from the rear end of the body 461, the extension 462 extends downward from the front end of the body 461, which is far away from the transfer driving end 43, the bottom end of the extension 462 is connected to the transfer low-bottom body 45, a concave arc groove 463 is formed on one side of the transfer driving end 43, which is far away from the body 461, a third inclined surface 464 is formed on the outer side of the extension 462, a fourth inclined surface 465 is formed on the inner side of the extension 462, and an inclined shoulder 466 is formed adjacent to the connection of the extension 462 and the transfer low-bottom body 45.

As shown in fig. 23, the jaw unit 50 includes two semicircles, one of which is a fixed jaw 51 and the other of which is a movable jaw 52. According to a preferred embodiment, the swing jaw 52 carrying the female tooth 521 can be closed on the fixed jaw 51 carrying the male tooth 511 and rotated open by 180 degrees. As shown in fig. 23, when movable jaw 52 is closed on fixed jaw 51, convex end 515 of male tooth 511 is inserted into end groove 524 of female tooth 521 (as shown in fig. 14A) so as to smoothly transfer coil 73 without getting caught between male tooth 511 and female tooth 521. Thereafter, as shown in fig. 24, the transfer member 41 moves up with the sheet member 31, pushing the coil 73 carried by the female tooth 521 upward so as to abut against the coil 73 carried by the male tooth 511, and then away from the jaw unit 50.

In the next step, as shown in fig. 24 to 27 and 15, the swing jaw 52 is opened and returned to the initial position, and then the sewing needle 80 sews the respective pairs of the stitches 73 on the male teeth 511 to sew the open end of the textile material.

In the present embodiment, the cross section of the tooth portion in which the coil 73 is fitted to the sewing thread, i.e., the cross section of the male tooth 511, is L-shaped, and as shown in fig. 29, the male tooth 511 includes a side extension 514 extending perpendicularly downward from the male extension 513.

The foregoing description is only of the preferred embodiments of the present invention, and it should be understood that the described embodiments are only a few, and not all, of the embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
