Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a device for knitting a cylindrical sock fabric with a heel formed by a sock knitting machine while reversing the front and back sides of the fabric. A circular or oval plate is fixed to the lower end of the lifting rod, and the clamping member is vertically inserted into the dial shaft of the dial located at the top of the cylinder so that it can rise and fall freely, and the plate is pressed against the bottom surface of the dial. By knitting the welt part while holding it between the plate and the dial, the sock fabric is formed into a double cylindrical bag inside the cylinder and is allowed to hang down.After knitting the course up to the toe part, the thread is cut. Next, the air in the cylinder is suctioned, and the welt section is immediately released to automatically knit the turned-over sock fabric.

When sock fabric is knitted using a conventional sock knitting machine, the welt part at the beginning of knitting hangs downward in the cylinder and is knitted sequentially from the heel to the toe. It is necessary to turn the sock material inside out so that it is on the surface, and for this purpose, it is necessary to turn it inside out manually, or to push the tip of the sock fabric slightly into the mouth of the suction tube and turn it inside out into the suction tube to cause suction. Since it is also done manually, it is inefficient and requires a lot of effort.

The present invention eliminates such drawbacks, and an embodiment thereof will be described in detail with reference to the drawings.
A dial 3 is provided above and facing the top cylinder 2 formed at the top of the dial 3.
A circular cutter 4 is rotatably provided on the top surface of the
Further, the dial 3 is fixed to the dial shaft 5 via the dial hub 6, and the dial cap 7, which is placed over the dial shaft 5, is attached to the top cylinder 2.
In the sock knitting machine, a circular or oval plate 10 is fixed to the lower end of the ascending rod 11 and rotates in the axial direction of the dial shaft 5. The lifting rod 11 is fitted into the vertical hole 5', so that it can be raised and lowered freely, and the upper part of the lifting rod 11 is made to protrude from the dial shaft 5, and a short cylindrical stopper 12 is screwed onto the upper end, so that the upper surface of the dial shaft 5 is fixed. and stopper 12
A pressure spring 13 is elastically loaded between them, and a wire 14 is connected to the stopper 12 to form a clamping member.
4 is connected to a control drum or a control chain (not shown), and the lifting rod 11 is pulled up and the plate 10 is brought into pressure contact with the lower surface of the dial hub 6 by indexing operation. 15 is the needle 16 is the sock fabric 17 is the sock fabric 1
The welt portion 18 of No. 6 is thread.

The present invention is thus constructed, and its operation is as follows. That is, as shown in FIG. 4, knitting starts from the welt part 17 as the cylinder 1 rotates, and as the number of courses progresses, it is formed by the tip of the welt part 17 as shown in FIG. When the diameter of the circular cavity becomes smaller than the diameter of the plate 10 located intermediate between the top cylinder 2 and the dial hub 6, the wire 14 is indexed by actuation of the control chain as shown in FIG. , the lifting rod 11 is pulled up against the elastic force of the pressing spring 13, and the plate body 10 is lifted up.
The upper welt part 17 is clamped by pressing the plate body 10 against the dial hub 6, and knitting is continued with the welt part 17 clamped to the dial 3 by the clamping member, as shown in FIG. As the welt portion 17 of the sock fabric 16 is held by the holding member and the number of courses progresses, the sock fabric 16 hangs down inside the cylinder 1 as a double cylindrical bag. At this time, the inner sock fabric 16, i.e., the sock fabric 16 with the welt portion 17 held between them, has the back knitted fabric on the surface, and the outer sock fabric 16, i.e., the one knitted by the needles 15. The knitted fabric is on the front side. As shown in FIG. 3, when the knitting of a predetermined course from the heel to the toe is completed, the thread 18 is cut, the air in the cylinder 1 is sucked, and immediately after that, the plate 10 and the dial 3 are knitted. When the clamping of the welt part 17 due to pressure contact is released by operating the wire 14, the outer cylindrical bag of the sock fabric 16 that has come off the needle 15 hangs down into the cylinder 1, and is turned inside out and the welt part 17 is turned upward. A certain sock fabric 16 is suctioned and conveyed to a predetermined location.

What is shown in the figure is a K-type sock knitting machine, but in the case of a double-cylinder sock knitting machine (Rib Knitta), which has an upper cylinder and a lower cylinder arranged above and below and knits with double-ended needles, the upper cylinder is By using a knitted fabric tensioning rod (not shown) loosely inserted into the lower cylinder and inserting the lifting rod 11 into the knitting fabric tensioning rod so as to be able to move up and down, and fixing the plate 10 to the lifting rod 11, the socks can be removed. The fabric 16 can be locked and knitted with the plate 10.

In this way, the present invention can automatically control the clamping member to move up and down according to the predetermined number of knitting courses to clamp and release the welt part 17, and while knitting the sock fabric 16, it can be turned over. The process of turning the front and back sides, which was conventionally performed afterwards, can be omitted, and therefore work efficiency can be significantly improved and labor can be saved. In addition, in the example, an example of a sock knitting machine equipped with a circular cutter is shown, but it can also be applied to a knitting machine of a model with scissors erected on the upper surface of the dial by erecting a clamping member vertically through the dial. can. Further, the present invention has a vertical structure, is easy to manufacture and install, and is a useful invention that is reliable in operation.

Claims (1)

[Claims] 1. A lifting rod is fitted vertically through a dial located above the cylinder or through a dial shaft fixed to the dial so as to be freely raised and lowered, and a circular or oval plate is fixed to the lower end of the lifting rod. A pressure spring that constantly presses down the lifting rod is loaded on the lifting rod, and a wire indexed by a control chain or a control drum is connected to the lifting rod, and the welt part is clamped by pressing the plate body against the lower surface of the dial. This device is characterized by knitting a predetermined course while knitting, and then releasing the clamp after knitting so that the back knitted fabric of the sock fabric becomes the front surface.
