Description

[Detailed description of the invention] The present invention relates to a knitting switching device for a knitting machine.

In each stage of knitting while the knitting machine is in use, outside the line width of the knitted material, knitting needles that do not participate in knitting should be pushed down to a lowered position where they do not come into contact with the cam of the carriage so that they are out of the knitting action of the cam of the carriage. An example of a technique is known in which the ends of the net are sectioned and shaped.

However, by configuring the knitting needles so that they can be lowered to a lowered position beyond the action of the knitting cams, there is a risk that the knitting needles may sink downward due to the impact during knitting, causing problems in knitting. .

The main purpose of the present invention is to solve the above problems, and also to disclose a technique that can be used for forming tuck knitting and the like.

And in this technical means, the knitting needles maintain their normal non-sinking position where they receive the action of the knitting cam, and the needles within the wire width at both ends of the net move into the knitting path where they are subjected to the action of the cam, and Needles outside the line width are guided to the non-knitted path, and as a means for this purpose, a positioner (hereinafter referred to as forming When the carriage is slid, the reversing actuation means of the cams provided on the carriage side engages with the forming instruction members. Further, a major feature is that the needle paths are distributed between the knitting path and the non-knitting path by the action of a cam which is switched via the reversing actuating means at the engaged and interlocked position. .

Further, in the present invention, by applying the combination of the forming instruction member and the carriage-side reversing operation means, it is possible to selectively switch between the tack cam and the needle feed cam for needle selection. This will further expand the scope of its use.

Similarly, if the raising cams 28 and 28' are held in the open position and the switching pin 49 is placed in the upper position, it is also possible to form a smooth stitch.

Next, when forming a tuck stitch, the switching pin 45,
45', 49, 49', 55, 55' are placed in the lower and rear positions and the carriage 7 is slid, the knitting needles in the U section and P section in Fig. 1 are at the knitting waiting position (B position). The knitting needles that will be tacked in the next stage of the knitting needles in section S in Figure 1 are aligned at the knitting waiting position (position B), and the knitting needles forming other stitches are aligned at the needle selection position (position C). Ru.

Therefore, when the next stage of knitting is performed, the knitting needles in the U section and the section in Figure 1 pass through the passing path (B-B), and the knitting needles in the knitting time position (B position) during the knitting period in the S section pass through the tuck path. (B-
F), the knitting needles at the needle selection position (C position) are used to form stitches.

Therefore, tuck knitting can be performed.

Since the present invention is configured as described above, like the prior art,
As in the case of a mechanical device that retracts the knitting needles outside the line width of the knitted material to a lower position where no knitting movement is applied by the cam, the knitting needles are lowered downward by the balance machine during knitting. There are no drawbacks that may interfere with the knitting process, and the mechanism that sets both ends of the wire width in conjunction with the reading operation of the forming pattern makes it possible to easily and accurately form the knitted fabric. It is convenient and has excellent effects, such as being able to be molded.
