Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a central control device for stitch quantity and thread guiding devices in circular knitting machines.

Normally, when changing the stitch size of a knitted fabric in a circular knitting machine, the cam position of each yarn feeder is adjusted individually to match the stitch amount to the desired stitch size. In other words, by adjusting the cam position, the operating locus of the needle is changed. by the way,
At this time, if the set position of the thread guide device that supplies the yarn to the knitting needles is not adjusted at the same time, the knitting needles and the thread path of the thread guide device will come into contact and the knitting needles will be damaged in an instant. Therefore, when changing the stitch count of a knitted fabric, it is necessary to adjust both the stitch amount and the thread guide device at the same time. This is a very troublesome work and requires a skilled person for adjustment. Moreover, in the case of a circular knitting machine with a large number of yarn feeders, the more yarn feeders there are, the more labor and time are consumed than necessary each time the stitches of the knitted fabric are changed, resulting in an increase in operating costs. .

The present invention has been made in view of the above problems, and provides a simultaneous central control device that can easily and quickly adjust the stitch amount and the position of the thread guide device without requiring special skill. An object of the present invention is to provide a circular knitting machine with multiple yarn feed ports.

The device of the invention achieving this object comprises a yarn guiding device supported by a yarn carrier ring support via a yarn carrier ring, a cam holder with a control cam for the knitting needles, and a cam holder with said yarn carrier ring support and cam holder. In a multi-yarn feed circular knitting machine comprising a supporting cam ring, the cam ring is divided into an inner cam ring and an outer cam ring connected by a guide means, and the yarn carrier ring support and the cam holder are mounted on the inner cam ring. The present invention is characterized in that a means is provided to allow only the inner cam ring to be moved up and down independently.

Preferably, the means by which only the inner cam ring can be raised and lowered independently includes an adjusting ring threadedly engaged with the inner cam ring, one or more small gears meshing with this adjusting ring, and a circular knitting machine surface. A set ring for supporting an adjustment ring may be added to these.

Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

In FIG. 1, reference numeral 1 indicates a cylinder, and on the outer periphery of this cylinder 1 are needle grooves 2 arranged in a circular manner and extending in the axial direction.
is formed. Each needle groove 2 accommodates a knitting needle 3 that is vertically slidable.

A cam holder 4 facing the cylinder 1 is fixed on an inner cam ring 6 by a screw 5.

A cam 7 for controlling or operating the knitting needles 3 is attached to the cam holder 4.

The sinkers 8, which cooperate with the knitting needles 3 during knitting, are slidable in the radial direction on a horizontally arranged sinker dial 9. The sinker 8 is controlled by a sinker cam 11 attached to a sinker cap 10. A sinker cap 10 is housed within a cap ring 12.

There is a drive gear 13 integrally attached to the lower part of the cylinder 1, which is normally on the same side as the cylinders 1 and # when driven from a drive source located in the machine. Reference numeral 14 denotes a base in which an inner cam ring 6 and an outer cam ring 16 are housed, which are connected by guide means, for example a guide pin 15. There are 6 guide pins 15 on the cam ring circumference.
There are several locations. The outer cam ring 16 has screw 1
7 to the base 14. The inner cam ring 6 can be moved up and down by the configuration described below. There is an adjusting ring 18 on the outside of the inner cam ring 6, and the inner ring 6 and the adjusting ring 18 are screwed together by threaded portions 19 (19a, 19b).

A set ring 21 is provided at the bottom of the adjust ring 18, and the adjust ring 18 is rotatably housed between the set ring 21 and the outer cam ring 16. j182 which is a sectional view taken along line 2-2 in FIG.
As clearly shown in the figure, a spring 20 is provided between the inner cam ring 6 and the adjusting ring 21, and this spring 20 pushes the inner cam ring 6 in the direction of the threaded portion 19b of the adjusting ring 18. This prevents the inner cam ring 6 from tilting due to the gap between the threaded portions 19.

The springs 20 are provided at about six locations on the circumference of the cam ring. Set ring 21 is attached to outer cam ring 16 by screws 22 as shown in FIG. Referring again to FIG. 2, the adjustment ring 18
A small gear 23 that meshes with the adjusting ring 18 is arranged at an appropriate position on the outside of the ring 18.The number of this small gear 23 may be one, but it is also possible to provide a plurality of small gears 23. The small gear 23 has a shaft portion 24 that protrudes through the outer cam ring 16.
is fixed. When the head groove 24a of the shaft portion 24 is turned with a screwdriver, the movement rotates the small gear 23 and further rotates the adjustment ring 18. This rotational movement of the adjusting ring 18 is controlled by the guide pin 1 through the threaded portion 19.
5 is used as a guide to move the inner cam ring 6 in the vertical direction.

Four to six yarn carrier ring supports 25 are arranged at equal intervals on the inner cam ring 6, and a yarn carrier ring 26 is attached to the tip of the yarn carrier ring support No. 2 by a screw 27. On the underside of the yarn carrier ring 26, a thread guide device 28 is connected to the screw 2.
It is attached by 9. This yarn guide device 28 has a holder 30 and a yarn carrier 31 for guiding the knitting yarn.

On the other hand, on the outer cam ring 16, there are cap ring supports 32 that penetrate through the approximate center of the yarn carrier ring support 25 and are arranged at equal intervals like the yarn carrier ring 26, and the tip of the cap ring support 32 A cap ring 12 is fixed to the cap ring 12 with a screw 33.

According to the present invention having the above-described structure and operation, only the inner cam ring can be raised and lowered independently, so that the cam holder and yarn carrier ring support placed on the inner cam ring, as well as the yarn guide device, are raised and lowered at the same time. . Therefore, the stitch amount and the position of the thread guide device can be adjusted extremely easily and in a short time without requiring any special skill, thereby improving productivity.
