Abstract

This paper relates to a cam device that prevents the needle lowering mechanism from malfunctioning while forming a large pattern in the process of knitting the pattern when knitting the back part of a sock.

In this paper, in order to achieve the above object, the cam is installed as long as the length of the cylinder, which is the position of the long needle, around the lower side of the sinker house, and the long roller is brought into contact with the roller of the pusher that operates the lowering mechanism. In the section being knitted, the lowering mechanism itself cannot operate.

Cam device of sock knitting machine {CAM DEVICES FOR SOCKS KNITTING MACHINE}

This paper relates to a cam device that prevents the needle lowering mechanism from lowering the needle while forming a large pattern in the process of knitting the pattern when knitting the back part of the sock.

The process of knitting a sock in a conventional sock knitting machine is as follows.

In other words, the knitting of the sock is made by knitting the torso while the cylinder equipped with the knitting needle continuously rotates in only one direction (the knitting is performed while both the short knitting needle and the long knitting needle are lowered), and the whole body is knitted. When knitting the rear axle part, the long knitting needles are all risen and the knitting is not made. When the knitting of the rear axle is completed, the knitting of the back part of the socks is made with all the knitting needles lowered.

By the way, when knitting the pattern in the back part knitting process, there is a part where the big needle does not go up according to the pattern. When you want to form a big pattern, the part where the big needle is not wide is wide. Knitting is not done because the lowering mechanism is raised to lower the large needle. Therefore, the pattern formed on the back of the socks could all be made small.

In view of the above, the purpose of this paper is to form a large pattern on the back of the sock, but to prevent the lowering mechanism from rising and lowering the needle.

In this paper, in order to achieve the above object, the cam is installed as long as the length of the cylinder, which is the position of the long needle, around the lower side of the sinker house, and the long roller is brought into contact with the roller of the pusher that operates the lowering mechanism. In the section being knitted, the lowering mechanism itself cannot operate.

The overall configuration of this draft is as shown in Figs. That is, although the illustration of the cylinder 7 part is omitted in FIG. 2, the sinker collection 2, which is the upper part of the cylinder 7, is shown and the needle lowering cam device 1 is installed below the cylinder.

On the sinker bottom surface 3 of the sinker collection 2, a cam 4 is fixedly installed as a bolt 6. The cam 4 is located at the position of a long needle, that is, the sinker collection 2 as shown in FIG. It is formed only in half, and the roller 4 is formed in the cam 4.

The needle lowering cam device 1 installed at the side of the sinker house 2 is provided with a push rod 10 operated by an air cylinder 11, and a lever having an adjustment bolt 12 in contact with the push rod 10. 13 is installed as a shaft 20, the lower end of the lever (14) is installed in contact with the lower end of the lever 21, the lower end of the lower portion 15 is formed in a structure that lowers the needle. On the other hand, a roller 9 is provided at the end 8 of the push rod 10 and the roller is in contact with the roller contact portion 5 of the cam 4 provided on the sinker 2 bottom.

The needle lowering cam device 1 is always located on the upper side by a spring (not shown) as shown in Fig. 2, while the trunk portion of the sock is knitted, and only a short uneven hand is rotated by 180 ° alternately from side to side. In the process of knitting the rear axle of the socks, each of the two short needles that are raised each time 180 degrees to the left and the short knitting needles are lowered, the operation of which is made by the air cylinder (11). That is, the head portion 26 of the knitting needle 25 is rotated to the lower end portion 15 of the lower portion 14, and the lower portion of the knitting needle is lowered by the cam when the lower portion touches the lower end portion 15 of the lower portion. Lower the needle. Then, the lever 13 in contact with the push rod rotates clockwise about the shaft 20 and lifts the lowering rod 14 upward. Therefore, the lower portion 14 is the end portion 15 descends about the shaft 21 and lowers the needle. In this state, when the knitting of the rear shaft part of the socks is all made, the cylinder rotates continuously in one direction again, and the back part of the socks is knitted. In the process of forming the pattern on the back part, the large needle goes up according to the pattern. Space is created. In this case, when the pattern is formed large, the space is wide so that the end portion 15 of the lowering stand 14 is raised to lower the knitting needle being knitted so that it is not knitted.

However, in this paper, since the cam 4 is installed on the bottom 3 of the sinker house 2 as much as the width of the needle, the roller 9 of the pusher 10 at the moment when the needle passes the lower end of the lowering stand 14. Since the ascend the cam 4, the push rod 10 pushes the lever 13 and accordingly the lower end 14 is lowered end. Therefore, while knitting, the lowering table 14 is forced to maintain a lowered state, so no matter how large a knitting pattern, the lowering table is raised so that the knitting needle is not lowered.

This design has a feature that the pattern on the back of the socks can be largely knitted.
