Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sinker cam changing device for a circular knitting machine, which can easily replace a sinker cam in accordance with a change in knitting application.

[0002]

2. Description of the Related Art For example, a circular knitting machine for knitting a sock is, as shown in FIG. The knitting needles 3 arranged, the top cylinder 4 and the sinker bed 5 fixed to the upper part of the cylinder 2, and the radially extending grooves 4a and 5a provided in the top cylinder 4 and the sinker bed 5 are slidably arranged. The sinker 6 includes a sinker 6, a sinker cap 7 supported on the knitting machine body so as to cover the sinker 6, and a sinker cam device 8 provided on a lower surface of the sinker cap 7.

The sinker cam device 8 comprises a center cam 9 and a plurality of receiving cams 10 to 16 as shown in FIG. 5, and is fixed to the lower surface of the sinker cap 7 by fixing means such as screws. The sinker cam device 8 is
Groove 4 provided in top cylinder 4 and sinker bed 5
a, cams 10-16 receiving sinkers 6 arranged at 5a
, And slide inward in the horizontal direction by the center cam 9.

In a circular knitting machine of the above type, when changing from a plain knitted fabric to a pile knitted fabric or changing the gauge or the number of stitches, the knitting timing is changed by replacing the sinker cam 9 of the sinker cam device 8. Since the sinker cam 9 is fixed to the lower surface of the sinker cap 7, the sinker cam 9 is replaced by removing the sinker cap 7 from the knitting machine body, removing the sinker cam 9 from the sinker cap 7, and attaching another sinker cam 9. It is done by attaching.

[0005]

In the circular knitting machine of the above type, the sinker cam of the sinker cam device is replaced by removing the sinker cap from the knitting machine main body. Since parts such as the yarn path of the yarn feeder, the yarn guide and the stop motion are arranged, it is impossible to remove the sinker cap from the knitting machine main body while keeping these parts as they are.
Therefore, the sinker cap cannot be removed from the knitting machine main body unless parts such as a yarn guide, a yarn guide and a stop motion related to a yarn feeder (not shown) are removed, and the sinker cam is replaced. In order to attach the sinker cap to the knitting machine main body, after attaching the sinker cap to the knitting machine main body, it is necessary to install parts such as the yarn path of the removed yarn feeder, the yarn guide and the stop motion, and replace the sinker cam. However, there is a problem that considerable labor and time are required.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has a sinker cam for a circular knitting machine in which a sinker cam can be easily replaced without changing the sinker cam from the knitting machine main body of the sinker cap when the knitting application is changed. It is intended to provide a switching device.

[0007]

According to the present invention, there is provided a sinker cam changing device for a circular knitting machine, wherein a notch large enough to allow a horizontally disposed sinker cam to pass through a sinker cap located at an upper portion of a cylinder is provided, and a sinker cam is provided on a lower surface. Is fixed to the upper surface of the sinker cap so as to cover the notch provided in the sinker cap. Therefore, the sinker cam can be easily replaced without removing the sinker cap from the knitting machine main body.

[0008]

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

In FIGS. 1 and 2, the same members as those in FIGS. 4 and 5 are denoted by the same reference numerals.

In FIG. 1, reference numeral 20 denotes a sinker cam holding member for fixing the sinker cam 9. The sinker cam holding member 20 is disposed on the upper surface of the sinker cap 21 so as to cover the notch 22 provided in the sinker cap 21. Notch 22 provided in sinker cap 21
Is formed at a portion corresponding to the sinker cam 9 of the sinker cam device 8 fixed to the lower surface of the sinker cap 21. The notch 22 provided in the sinker cap 21 is set to such a size that the horizontally disposed sinker cam 9 can pass through. The sinker cam 9 is fixed to the lower surface of the sinker cam holding member 20 by a fixing screw 23 as shown in FIG. The sinker cam 9 may be integral with the sinker cam holding member 20.

The sinker cam device 8 is connected to the sinker cap 2.
In order to incorporate the receiving cams into a plurality of receiving cams 10 to 1 shown in FIG.
6 is fixed to the lower surface of the sinker cap 21 with a normal fixing screw. The plurality of receiving cams 10 to 16 are arranged in a peripheral portion excluding the notch 22 on the lower surface of the sinker cap 21.

Next, the sinker cam 9 is fixed to the lower surface of the sinker cam holding member 20 via the fixing screw 23, and the sinker cam holding member 20 to which the sinker cam 9 is fixed covers the notch 22 provided in the sinker cap 21. Is disposed on the upper surface of the sinker cap 21, and the sinker cam holding member 20 is fixed to the upper surface of the sinker cap 21 via the fixing screws 24, 24.

FIG. 3 shows a sinker cap 21 to which the sinker cam device 8 is attached. The sinker cap 21 shown in FIG. 3 is attached to the main body of the circular knitting machine so as to cover the sinker 6 slidably disposed in the grooves 4a, 5a provided in the top cylinder 4 and the sinker bed 5 by a usual method. .

In the case of knitting socks on a circular knitting machine, in order to change the plain knitted fabric to the pile knitted fabric or to change the gauge or the number of stitches, the sinker cam 9 of the sinker cam device 8 is replaced. It is necessary to change the knitting timing.

To replace the sinker cam 9 of the sinker cam device 8 provided on the sinker cap 21, the fixing screws 24, 24 are removed from the sinker cap 21, and then the sinker cam holding member 20 is removed from the sinker cap 21.
The sinker cam 9 is removed from the sinker cam holding member 20 by removing the fixing screw 23 from the removed sinker cam holding member 20, and another sinker cam 9 is attached to the sinker cam holding member 20 from which the sinker cam 9 has been removed.
And a sinker cam holding member 20 to which another sinker cam 9 is attached.
Sinker cam holding member 2 which is disposed on the upper surface of sinker cap 21 so as to cover
0 to the sinker cap 21 via the fixing screws 24, 24.
By fixing to the upper surface of

As described above, the replacement of the sinker cam 9 of the sinker cam device 8 provided on the sinker cap 21 can be performed without removing the sinker cap 21 from the knitting machine main body. The work efficiency is greatly improved.

[0017]

As described above, according to the present invention, the sinker cap located at the upper part of the cylinder of the circular knitting machine is provided with a notch having a size large enough to pass the sinker cam horizontally disposed, and the sinker cam is fixed to the lower surface. The fixed holding member is fixed to the upper surface of the sinker cap so as to cover the notch of the sinker cap, so that the sinker cam can be easily replaced when the knitting use is changed without removing the sinker cap from the knitting machine main body. .
