Description

[Detailed description of the invention] [Subject of the invention] The present invention provides a replacement thread opening that allows the knitting yarn to be replaced in the carriage mounted on the needle bed, and a replacement thread opening that allows the knitting yarn to be replaced at a position outside the operating knitting needle section of the needle bed. A plurality of knitting yarn retainers each capable of retaining a plurality of knitting yarns for use separately and movable separately between a working position where the knitting yarn can be inserted into a replacement yarn opening and a non-working position where the knitting yarn cannot be inserted. Stop body,
The present invention relates to a thread changing device for a hand knitting machine, which is mounted at the outer position by a support member having a threading prevention means.

[Field of application of the present invention] This yarn exchange device is capable of smoothly removing a knitting yarn from two yarn openings and inserting another knitting yarn separately or at the same time without causing any threads to get caught. In limited cases, in addition to multicolor simultaneous knitting, when using multicolor knitting yarns in knitting based on single yarn supply (for example, multicolor step stripes, multicolor sliding stitches, multicolor tats, etc.) used.

[Prior art]

In this type of conventional technology, for example,
As seen in No. 172387, there was one in which a knitting yarn gathering part was formed at the lower part of the support member.

Then, in this collecting section, a plurality of knitting yarns, that is, the intermediate portion of the knitting yarns that span each knitting yarn restraining body between the knitted fabrics, are placed at a position corresponding to approximately below the passage path of the exchange yarn introduction groove. , is a summary.

[Problems with conventional technology and their technical analysis]

Since this knitting yarn collecting section is located directly below where the carriage passes, the knitting yarn that has passed between the collecting section and each knitting yarn stopper will be removed from the knitted fabric provided thereon when the carriage slides. This caused inconveniences such as getting caught on the end of the presser foot or the presser wheel, wrapping around it, or coming off again, making knitting impossible. This is due to the structure of the knitting yarn gathering section and the mutual cooperation with the retaining body.

[Technical Problem] The present invention modifies the structure of the knitting yarn gathering section and the coordination position of the gathering section and each restraining body, so that the crossing of the knitting yarn obstructs the operation of the knitting presser foot and the presser wheel. The challenge is to prevent this from happening.

[Technical means]

That is, one side flat portion of the support member that supports the knitting yarn restraining device is attached to a position outside the working needle section of the needle bed. This support member has a hanging portion formed from the flat portion, which extends horizontally to become a rising portion again, and then a flat portion on the other side is formed for fixing the knitting yarn restraining device. Therefore, the space between the two mounting plane parts is substantially square-shaped, and the plane part on one side (needle bed side) is higher than the other side (stopping device side).

Also, when the carriage is mounted on the needle bed,
The knitted fabric pressing device portion of the carriage was configured to be positioned so as to face into the molded portion in the shape of the attachment member. An arm piece is made to protrude in the direction of the working knitting needles at the middle of the hanging part from the one side plane part, and a protrusion piece is formed on the end side of this arm piece so as to extend diagonally upward at the rear. As will be explained in the function section of the next section, this protrusion plays the role of holding together multiple knitting yarns.

[Effect of technical means]

In the present invention, when changing the knitting yarn and stopping the knitting yarn, the intermediate portion of the yarn passing from the knitted fabric to the knitting yarn restraining body is locked to the protruding piece. Since the projecting piece is tilted backward and upward at the hanging part of the support member and is located on the working needle side, the intermediate part of the knitting yarn that crosses between it and the retaining member is stretched backward in the shape of <. Ru. Therefore, the corresponding positions of the knitting fabric presser and presser wheel of the carriage are arranged within the angle formed by the character < when viewed in the lateral direction.

[Special effects produced by the present invention]

According to the present invention, the knitting yarn extending between the end of the knitted fabric and the knitting yarn restraining body can be retracted backward from the front end of the needle bed by simply hanging the idle yarn, etc. on the protruding piece that is the hooking part. When the carriage passes,
There is no risk of it getting caught on the edge of the knitting presser foot or the presser wheel. Furthermore, since the projecting piece is molded integrally with the support member and the knitting yarn is hung on the upper bent portion thereof, the operation is simple and the position does not move, and the knitting yarn does not come off.

Therefore, the knitting yarn can be reliably protected, and the knitted fabric will be in a tensioned state, resulting in less fluctuation during knitting and the occurrence of stitch defects and the like.

〔Example〕

In the figure, 1 is a needle bed, 2 is a carriage mounted on the needle bed 1, 3 is a fabric presser that is fixed to the lower surface of the carriage and prevents the knitted fabric 4 from advancing, and 5 is a fabric presser. It is a presser wheel. Reference numeral 6 denotes a support member, one side of which has a flat surface 6a fixed to the front surface of the needle bed with a screw 7;
A hanging portion 6b, a horizontal surface 6c, a rising portion 6d, and a high plane portion 6e are formed, and a knitting yarn restraining device 8 is fixed to the plane portion 6e with screws 9. Therefore, this support member 6 has a substantially square shape in cross section, and has a hanging portion 6b.
An arm piece 6f protrudes from the middle in the direction of the working knitting needles. A projecting piece 6g that is tilted rearward and bent upward is formed on the end side of the arm piece 6f.

10A, 10B, 10C, and 10D are knitting yarn restraining bodies, which are arranged in the restraining device 8 so as to be movable back and forth separately. Reference numerals 11A, 11B, 11C, and 11D are guide wheels rotatably locked to each of the knitting yarn restraining bodies, each of which guides each knitting yarn guided from a knitting yarn tension adjusting device (not shown) provided on the needle bed. is locked. Also,
Each of 12A, 12B, 12C, and 12D is a prevention member that prevents the knitting yarn from coming off the guide ring. 1
Reference numeral 3 denotes a replacement yarn opening which is attached to the carriage and is provided with knitting yarn guiding means, and 13A and 13B are the first and second yarn openings, respectively. Therefore, the guide wheel 11A at the position shown in FIG. 1 moves to the second clue 13B.
11D is a working position for feeding the yarn to the first yarn opening 13A, and 11B and 11C are rest positions for removing the knitting yarn from both yarn openings.The position of this guide wheel is determined by the operator according to the desired type of knitting. is the one that performs the selection operation. With this configuration, the knitting yarn T passed from the guide ring to the protrusion is pulled backwards as shown by the thick solid line (the double-dot chain line T1 is the knitting yarn crossing state in the conventional type), which hinders carriage running. not become,
You can easily reach your desired goal.
