Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a swingable surface roller of a winding device of a loom, and a method for reducing the length of a woven fabric woven at a weave as short as possible until it reaches a surface roller. To reduce the movement of the woven fabric during reed beating, to prevent the woven fabric from sagging, to eliminate pile deformation, to reduce the area occupied by the Surf Ace roller, and to increase the winding diameter of the cross roller. It is an object.

Conventionally, the woven fabric is once supported by the breast beam, then goes around the Surf Ace roller and is rolled up by the cross roller, but the length of the woven fabric until it comes into contact with the Surf Ace roller Due to the long length, the woven fabric moves a lot during beating, causing sagging between the woven fabric and the pre-stroller.

Furthermore, when a pickle winding device is used, a surf ace roller with a diameter of 5 inches or more is required, and therefore the space for providing a large winding diameter of the cross roller at the front of the loom is limited.

Therefore, by making the distance between the Surf Ace roller and the weave as short as possible to prevent the woven fabric from sagging, and by expanding the space in which the cross roller is installed at the front of the loom, the amount of fabric wound onto the cross roller can be reduced. The present invention attempts to increase this.

An example of implementation of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a first Surf Ace roller shaft that is pivotally supported by a frame (not shown) via a metal 2, and the coaxial shaft 1 supports the first Surf Ace roller 3, a taking-up wheel 4, and a sprocket wheel 5 integrally with the coaxial shaft 1. do.

Further, a pair of pile arms 6 are supported on the shaft 1 so as to be swingable.

A second Surf Ace roller shaft 7 is supported between the tips of the pair of pile arms 6, and a second Surf Ace roller 8 is rotatably supported on the same shaft 7.

A sprocket wheel 9 is provided integrally with the second surf ace roller 8 as a means for transmitting the rotation of the first surf ace roller 3, and a chino 10 is installed between the sprocket wheels 5 and 9.

Of course, in addition to the above-mentioned chino transmission, a belt or a gear may be used as the rotation transmission means for the first Surf Ace roller.

A forked portion is formed at the lower end of the pile arm 6, and a pile motion rod 11 is pivotally attached to the turning portion.

Reference numeral 12 designates a pair of twitch roller arms that are swingably supported on a frame (not shown), and a twitch roller 13 is rotatably supported at a receiving portion at the tip of the arm.

The twitch roller arm 12 is connected to the pile arm 6 by a link 14.1. In accordance with the oscillating movement of the pile arm 6, the twitch roller arm 12 also oscillates.

15 is a presto beam, 16 is a presto rod, 17 is a cross roller, 18 is a cross guide roller, and 19 is a woven fabric.

Now, as the taking-up wheel 4 rotates as the loom rotates, it receives power from the driving side (not shown) and rotates.
This rotation rotates the first Surf Ace roller 3 together with the Surf Ace roller shaft 1.

The first surf ace roller 3 is made of Sufrocket foil 5
, a chain wheel 10, and a sprocket wheel 9, the rotation is transmitted to the second surf ace roller 8.
At the same time, since the cross roller 17 is in pressure contact with the first Surf Ace roller 3, the same roller 17 also rotates.

Therefore, the winding speed of the cross roller 17 and the rotational circumferential speed of the second surf ace roller 8 are the same.

As shown in FIG. 1, the cloth woven with a weave (not shown) is supported by the bracelet strand 16, goes around the second surf roller 8, and is connected to the cross roller 17 by the diameter of the twitch roller 13 and cross guide roller 18. It is rolled up.

When the pile motion rod 11 reciprocates as the loom rotates, the pile arm 6 loosely fitted to the Surf Ace roller shaft 1 also swings around the Surf Ace roller shaft 1.

On the other hand, the twitch roller arm 1 is connected to the pile arm 6 by the link 14 by the swinging of the heil arm ro.
2 also makes a rocking motion, and the twitch roller 13 supported at its tip swings in synchronization with the second surf ace roller 8.

During this time, the woven fabric 19 is wrapped around the outer periphery of the second Surf Ace roller 8 in an interval corresponding to the angle α, as described above, and then passed through the twitch roller 13, the cross guide roller 18, and then wrapped around the cross roller 17. During the pile motion of the second Surf Ace roller 8, since the twitch roller arm 12 is also connected to the pile arm 6 by a link 14, it generates a rocking motion in the same way as the pile arm 6, and the twitch roller attached to its tip causes a swinging motion. 13 also swings in the same relative positional relationship as the second surf ace roller 8.

For this purpose, the woven fabric that is wound around the second Surf Ace roller at a circumferential angle of Therefore, the woven fabric passes through the cross guide roller to the cross roller 17 without changing the length from point A where the woven fabric leaves the second Surf Ace roller to point B where the woven fabric contacts the cross guide roller. It is rolled up.

As described above, the device of the present invention includes two Surf Ace rollers, the first and second Surf Ace rollers, the second Surf Ace roller is located above the first Surf Ace roller and near the presto beam, and the second Surf Ace roller is located above the first Surf Ace roller near the presto beam. Because the rotation is conducted by the Surf Ace roller, it is necessary to use a Surf Ace roller with a diameter of 5 inches or more in conventional methods such as pickle winding, but in the device of the present invention, the first Surf Ace roller It has become possible to make the diameter of the cross roller much smaller, and in order to keep both rollers within a predetermined height range, the winding diameter of the cross roller can be increased accordingly.

In addition, since the second Surf Ace roller is located just in front of the presto beam, the second Surf Ace roller can approach the woven fabric, shortening the distance between the point where the woven fabric contacts the second Surf Ace roller and the woven fabric. It becomes possible to
This eliminates the loosening of the woven fabric, reduces the movement of the front, and prevents the woven fabric and warp from sagging, making it possible to weave a uniform pile.
