Description

[Detailed Description of the Invention] In a horizontal stockinette knitting machine, the knitting carriage is equipped with a brush device, and during knitting work, the latch of the knitting needle protruding from the tuyere at the upper end of the needle bed is opened and held in that state. This prevents the latch from closing due to vibrations, etc., but when using a presser to suppress stitches, the presser adapts to the knitting direction each time the carriage reaches the reciprocating end and changes the knitting direction. The tip of the brush that is facing the tuyere is touched and the tip of the brush is repeatedly bent, which causes the tip of the brush to bend. If this happens, the latch suppressing action may become unsmooth, making the knitting work inconvenient.

The present invention improves on this by providing a movable brush device and moving the brush device in synchronization with the movement of the brush device into and out of the tuyere for a switching operation such that the carriage reaches the reciprocating end and the presser adapts to the knitting direction. By moving the brush tips away from the tuyeres, contact with the presser is avoided. A knitting carriage is equipped with a movable brush to release the needle latch and hold it down, and when the carriage reaches the reciprocating end, the brush is moved in synchronization with this, and the tip of the latch is moved. It is characterized by being made to be evacuated through the tuyere.

Embodiments of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a needle bed which faces symmetrically in a chevron shape, 2 a knitting carriage that moves reciprocally along the needle bed, a brush 3 is provided on the opposing surface, and the tip thereof is connected to the needle bed 1,
During the knitting operation of the knitting needles a, which face the so-called tuyere 4 and are installed in parallel on the needle bed 1 by the reciprocating movement of the carriage 2, when they protrude from the tuyere 4, the brush 4 opens the latch b and the state This was done to prevent latch b from turning over and closing the hook portion of needle a due to vibration or the like.

Reference numeral 5 denotes a presser that accompanies the carriage 2 and moves downward into the tuyere 4 to suppress the knitted stitches to prevent the stitches from floating, as shown in FIG. When the presser reaches the reciprocating end and the knitting direction changes, the other presser simultaneously moves upward from the tuyere 4 and moves downward into the tuyere 4 to adapt to the knitting direction and suppress the stitches. I made it work.

The above is well known in the art, but when the presser 5 at the reciprocating end of the carriage 2 is operated to convert, the presser 5 that comes out and retracts from the tuyere 4 touches the tip of the brush 3 facing the tuyere 4 and bends the tip of the brush. Therefore, if this is done frequently, the tip of the brush will become bent, which will cause problems in its ability to hold down the brush.

The present invention solves this inconvenience by providing a movable brush device so that when the presser 5 comes out and goes down, the brush 3 is moved away from the tuyere 4 to avoid contact with the presser 5.

That is, the bracket 6 provided on the opposite surface of the carriage 2
A brush 5 is attached to a driven piece 8 which is provided to swing on a shaft 7.
Attach it with the handle rod 9 and move the brush 5 together with the driven piece 8 on the shaft 7.
A slope piece 10 is integrally fixed to the lower surface of the free end of the driven piece 8, and a sliding piece 11 is provided on the bracket 6 correspondingly, and its upper end is connected to the slope piece 10. The sliding piece 11 is moved back by the spring 12 so that it faces the slope 10a, and the upper end of the sliding piece 11 is separated from the slope 10a under normal conditions.
When the sliding piece 11 is advanced against the spring 12, its upper end touches the slope 10a, and the slope pushes up the free end of the driven piece 8 via the slope piece 10, causing the driven piece 8 to swing. As a result, the brushes 3 attached thereto are swung together so that their tips are moved away from the tuyere 4 as shown by the dotted lines in FIG. When the upper end separates from the slope 10a, the driven piece 8 is moved back by the spring 13, and accordingly, the tip of the brush 3 is automatically brought to face the tuyere 4, and the sliding piece 1
A trochanter 14 is provided protruding from the lower surface of the carriage 2, and a receiving cam 1 is provided at an appropriate position on the reciprocating end of the carriage 2.
5 is fixedly installed, so that when the carriage 2 reaches the reciprocating end, the trochanter 14 abuts against the receiving cam 15 as shown in FIG.
0, the brush 3 was swung as described above, and its tip was withdrawn from the tuyere 4, synchronizing with the movement of the presser 5 in and out of the tuyere 4.

In the embodiments described above, the tip of the brush 3 was moved away from the tuyere 4 by rotation, but
The withdrawal operation can also be performed by vertical movement of the brush 3.

In this way, according to the present invention, the brush is movably provided, and when the carriage reaches the reciprocating end during knitting, the tip is withdrawn from the tuyere in synchronization with the switching operation of the presser. During the switching operation, this does not come into contact with the brush, thus preventing the tip of the brush from becoming bent due to contact with the presser, ensuring the smoothness-retaining action of the brush, and making the knitting work smoother. has.
