Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a winding device for a loom, and relates to a winding device for a loom, which is caused by slipping of the woven fabric on the surface of a roller such as a surf ace roller that supports and guides it during pile motion. In order to prevent pile collapse of the fabric, even when the Surf Ace roller swings, the length of the fabric between the Surf Ace roller and the Twitch roller is kept constant so that no slip occurs between the roller surface and the fabric. In order to do this, the twitch roller is supported so as to swing in conjunction with the swing of the pile arm.

Looms with twitch rollers have been known in the past, but
In a loom that performs pile motion, the woven fabric is passed from the weaving tongue surf ace roller to the twitch roller. Since the distance between 1 and 4' changes between 1 and 4', the sheet is pulled or relaxed in the opposite direction from being rolled up by the cross roller, and this process is repeated.

For this reason, the tension roller is pulled by a spring to absorb the slack in the woven fabric caused by the above-mentioned operation by the expansion and contraction of the spring, but the woven fabric sometimes slips on the surface of the woven fabric face roller, causing the pile to collapse.

The device of the present invention aims to prevent the above-mentioned sag from occurring and also prevent the pile from collapsing by moving the twitch roller in accordance with the pile motion.

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

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

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.

The second surf ace roller serves as a means of transmitting the rotation of the first surf ace roller.
A sprocket wheel 9 is provided integrally with a surf ace roller 8, 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 linked to the pile arm 6 by a link 14, and as the pile arm 6 swings, the twitch roller arm 12 also swings.

The twitch roller arm 12 may be fixed directly to the pile arm 6 without being connected to the pile arm 6 by the link 14 as described above.

15 is presto beam, 16 is presto rod, 17 is cross roller, 18 is cross kite loaf = -, 19
is a woven fabric.

Now, taking up wheel 4 according to the rotation of ill
When the roller rotates upon receiving power transmitted from a driving side (not shown), the rotation causes the first Surf Ace roller 3 to rotate together with the Surf Ace roller shaft 1.

The first surf ace roller 3 is a sprocket wheel 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 speed of the second surf ace roller 8 are the same.

The cloth woven using the woven fabric (not shown) is as shown in Figure 1.
It is supported by a prestro rod 16, goes around the second surf ace roller 8, passes through a twitch roller 13, a cross guide roller 18, and is rolled up by a cross roller 17.

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 a link 14 due to the swinging of the pile arm 6.
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 at an angle α, as described above, and then wrapped around the cross roller 17 via the twitch roller 13 and the cross guide roller 11. 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 arm 12 supported at its tip causes a rocking motion. The roller 13 also swings under the same relative positional relationship as the second surf ace roller 8.

For this purpose, the area around the second Surf Ace roller is
The woven fabric is wound at a circumferential angle of 1 without reducing its winding angle, and the woven fabric is wound from the second Surf Ace roller without changing the winding angle of the Twitch roller 13. The woven fabric is wound up by the cross roller 17 through the cross guide roller without changing the length from a distant point A to a point B where the woven fabric contacts the cross guide roller.

As described above, in the device of the present invention, the twitch roller arm performs a oscillating motion in synchronization with the oscillating motion of the pile arm, which oscillates due to the reciprocating motion of the pile motion rod. The relative positional relationship with the ace roller is constant, and the woven fabric between both rollers is never stretched or relaxed, so the woven fabric never slips on the roller surface and there is no possibility of pile collapse. It can be prevented.
