Detailed ways

The embodiments of the present invention are described below with reference to the drawings, in which the same components are denoted by the same reference numerals. In the case of no conflict, the following embodiments and technical features in the embodiments can be combined with each other.

In the method for transferring fabric loops of the present invention, three parts are used, such as the transfer needle shown in Figures 1 to 4, the needle guard shown in Figure 5, and the slit teeth shown in Figures 6-11.

FIG. 1 shows a perspective view of the transfer needle 4a of the present invention. The transfer needle has a transfer needle body 41, and the head of the transfer needle body 41 (the end contacting the fabric loop) has a transfer portion 42. The transfer needle body 41 is in the shape of a thin and elongated sheet, and the transfer part 42 is curved and deviates from the axis of the transfer needle body 41. Preferably, the transfer part 42 is arc-shaped, tapering from the end of the transfer needle body 41, and the end is pointed. . The tail (the end far from the fabric loop) of the transfer needle body 41 has a transfer needle protrusion 411, which is engaged with the transfer plate of the fabric transfer device, and pushes and pulls the transfer needle protrusion 411 to transfer The needle moves inward and forward in the radial direction, and can also move up and down to transfer fabric loops.

Figure 2 shows a three-dimensional view of the transfer needle 4b of the present invention. The difference from the transfer needle 4a is that its shape is symmetrical to the transfer needle 4a. When in use, a pair of

transfer pins

4a and 4b are required to be used together. Specifically, the

transfer pins

4a and 4b are attached together. The transfer pin main body 41 is made into a sheet shape, which is also to reduce the volume when the two are attached together, which is more environmentally friendly.

Figure 3 shows the state diagram of the

transfer pins

4a, 4b when in use. The transfer needle bodies 41 of the

transfer needles

4a and 4b are attached together, and the respective transfer parts 42 form a groove, a transfer needle groove 43, which is used to accommodate the slit teeth and stitches of the fabric sewing device. The function and general structure of the mouth teeth are well known to those skilled in the art and will not be described here.

Figure 4 shows another embodiment of the transfer needle of the present invention. The difference from the first embodiment is that the transfer needle body 41 has a certain thickness, so that a groove can be opened on the head of the transfer needle body 41, that is, the transfer needle Needle groove 43. The transfer pin groove 43 is also used to accommodate the slit teeth. Preferably, the transfer needle groove 43 is asymmetrical, with a gap at the end of the groove, so that the needle of the hosiery needle 1 can slide into the transfer needle groove 43 more smoothly (see FIG. 6). The tail (the end far from the fabric loop) of the transfer needle body 41 has a transfer needle protrusion 411, which is engaged with the transfer plate of the fabric transfer device, and pushes and pulls the transfer needle protrusion 411 to transfer The needle moves inward and forward in the radial direction, and can also move up and down to transfer fabric loops.

Figure 5 shows the structure of the needle guard 4c. The needle guard 4c is used in conjunction with the

transfer needles

4a and 4b. The needle guard 4c has a needle guard main body 45, and a needle guard holding portion 46 extends downward from the front end of the needle guard main body 45 (the end contacting the loop of the fabric). Preferably, the needle guard clamping portion 46 extends vertically downward.

The needle guard body 45 has a needle guard protrusion 451 on the lower side of the rear end (the end away from the loop of the fabric). The needle guard protrusion 451 is clamped to the transfer plate of the fabric transfer device. Pushing and pulling the needle guard protrusion 451 can move the transfer needle inward and forward in the radial direction, and can also move up and down for fabric looping. Transfer. A needle guard chamfer 47 is formed at the joint between the needle guard body 45 and the needle guard clamping portion 46.

The needle guard body 45 has a plurality of needle guard grooves 452 on the lower side to be combined with the transfer disc of the fabric transfer device. In use, the

suture needles

4a, 4b are inserted between the two needle guards 4c, and are located in the gap formed by the needle guard clamping portions 46 of the two needle guards.

As shown in FIG. 6, the slit teeth 6a have an elongated body 61 and an engaging portion 62, the engaging portion 62 extends from the upper end of the elongated body 61, and the two combined together form an approximate 7-shape. The elongated body 61 includes a needle portion 611 at the lower end and a supporting portion 612 at the upper end.

Fig. 7 shows a schematic diagram of the slit teeth 6a mounted on the tooth seat 6e. Fig. 8 shows a schematic diagram of the slit teeth 6a mounted on the tooth holder 6d. The

tooth seats

6e and 6d form a complete circular tooth seat. The half tooth seat 6d in FIG. 3 can be turned down by 180 degrees, so that the two semicircular tooth seats are perfectly aligned. The overall 7-shaped slit teeth 6a are installed on the tooth seat 6e of the fabric transfer device, specifically, hung on the groove of the tooth seat 6e through the engaging portion 62, and the elongated body 61 is installed in the groove of the tooth seat 6e. Wherein, the supporting portion 612 is completely embedded in the groove of the tooth seat 6e, and only the needle-shaped portion 611 is exposed. Similarly, slit teeth 6b (described below) are mounted on the tooth seat 6d of the fabric transfer device.

In order to make the slit transfer teeth 6a and the slit teeth 6b be more closely mounted on the tooth seat 6e, the further detailed structure of the slit teeth 6a ensures the technical effect, which will be described below with reference to FIGS. 1 and 4.

As shown in FIG. 9, the height H of the supporting part 612 matches the height of the tooth seat 6e, so that the supporting part 612 does not expose the tooth seat 6e after installation, and only the needle-shaped part 611 is exposed outside the tooth seat 6e. The width W of the support portion 612 matches the radial depth of the groove of the tooth seat 6e, so that the outer surface of the support portion 612 is flush with the radial outer surface of the tooth seat 6e after installation, and neither sinks nor protrudes. The effect afterwards is shown in Figure 7.

The lower side of the engaging portion 62 has an engaging protrusion 621, and a groove is formed between the engaging protrusion 621 and the supporting portion 612, so that the slit teeth 6a can be tightly hung on the groove of the tooth seat 6e. The upper surface of the engaging portion 62 has a fixing groove 623 to cooperate with the tooth seat 6e, so that the slit tooth 6a can be firmly connected to the groove of the tooth seat 6e. The end of the engaging portion 62 has an upwardly warped portion 622 for engaging with the tooth seat 6e so as to make the two contact closer.

FIG. 10 shows the structure of the needle-shaped portion 611. The outer side of the needle part 611 (the side radially outward after being installed on the tooth seat 6e) has a needle part groove 6111, which is used to align the tooth seat after the tooth seat is turned 180 degrees. The needle-shaped part 611 of the slit tooth on the tooth seat can overlap in the groove 6111 of the needle-shaped part 611 of the slit tooth of the upper tooth seat, so that the subsequent stitch transfer is smoother.

Figure 11 shows the structure of another embodiment of a slit tooth 6b. The outer side of the elongated body 61 of the slit tooth 6b (the side radially outward after being installed on the tooth seat 6e) has a suture groove 613, which is used for the suture groove 613 To accommodate the stitching needle 7b of the sewing machine (see Fig. 13), two stitching needles 7b are stitched alternately, thereby stitching the toe of the sock together.

Figure 12 shows the positional relationship between the slit teeth 6a, the transfer needle 4a, the transfer needle 4b and the two needle guards 4c. The slit teeth 6a are inserted into the transfer needle groove 43 formed by the transfer needle 4a and the transfer needle 4b together, and the transfer needle 4a and the transfer needle 4b are inserted into the gap between the two needle guard pieces 4c.

As shown in Figure 14, remove the socks 201 in Figure 13 and move the transfer device above the hosiery needle 1 so that the hosiery needle 1 is located below the gap formed between the two needle guards 4c.

As shown in Fig. 15, the needle guard 4c is moved downward so that the hosiery needle 1 passes through the gap formed between the two needle guards 4c. The needle guard 4c continues downwards until the fabric 8 is pressed on the needle release disk 2. This is to ensure that the fabric 8 is under the tongue of the hosiery needle 1 in preparation for the successful transfer of stitches.

In FIG. 16, the needle guard 4c is moved radially outward to separate from the hosiery needle 1.

In Figure 17, the transfer needles 4a, 4b are moved radially inward until the needle of the hosiery needle 1 is located in the transfer needle groove 43 formed by the transfer needles 4a, 4b, and the transfer needle groove 43 is located on the hosiery needle 1. Between the main body and the needle tongue.

In Figure 18, the needle guard 4c is moved radially inward, so that the hosiery needle 1 is between the gap formed between the two needle guards 4c. At this stage, the position of the needle guard 4c relative to the position of the hosiery needle 1 is more radially outward than the stage shown in FIG. 8 to avoid blocking the upward movement of the fabric 8 in the next stage.

In Fig. 19, if the needle removal disk 2 is moved upwards, and the fabric 8 is pushed upwards, the fabric 8 will move upwards along the hosiery needle 1 accordingly.

In Fig. 20, the fabric 8 has driven the needle tongue of the hosiery needle 1 upward, so that the needle tongue is closed, so that the opening of the hosiery needle 1 is closed.

In Figure 21, the needle tongue of the hosiery needle 1 is placed on the outer side of the transfer needle 4a (the radially outer side centered on the shaft of the hosiery tube 3), so that the fabric 8 can be smoothly transferred from the hosiery needle 1 to the transfer needle. Needle 4a on the transfer part 42.

In Fig. 22, the transfer device is moved upward. At this time, the fabric 8 has been transferred to the hosiery needle 1, and the needle guard 4c is dragged under the fabric 8, so the socks can move upward.

In Fig. 23, the ejecting disc 2 is moved downward.

In Fig. 24, the green sheet 201 moves radially inward and cooperates with the de-pinning disc 2 and the hosiery needle 1 to prepare for knitting the next fabric.

Figures 25-32 show the working process of the transfer slit teeth 6a.

In FIG. 25, the slit teeth 6a are mounted on the tooth seat 6e, and the slit teeth 6b are installed on the tooth seat 6d. On the tooth seat 6e, the slit teeth 6a are fixed on the tooth seat 6e through a pressing plate 6c and a fixing plate 6f. On the tooth seat 6f, the slit teeth 6b are fixed on the tooth seat 6d through a pressing plate 6c. The tooth seat 6e and the tooth seat 6f form a complete round tooth seat. When docking, the air cylinder drives the tooth seat 6d to turn 180 degrees below the tooth seat 6e to achieve butt joint, so that the slot teeth 6b also turn 180 degrees to butt with the slot teeth 6a. After the butting, the pressure plate 6c on the slit teeth 6a is pushed down by the air cylinder, so that the loops of the upper and lower fabrics 8 (such as socks) are combined and butted.

As shown in Figure 25, on the hosiery machine, the last loop of the fabric 8 has been transferred to the transfer needles 4a, 4b (sleeved on the transfer needles 4a, 4b), and then the

slit teeth

6a, 6b are inserted into the transfer The
