Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a warp beam holder in a loom.

[0002]

2. Description of the Related Art A loom is equipped with a weaving device used when replacing members such as warp beams of the loom.

A warp beam around which a warp is wound, a warp cutting detection device for detecting the cutting of the warp, a plurality of heddle frames, and a reed supported by the front heddle frame are detachably supported by the machine device. ing. Then, the warp is fed from the warp beam and passed through the warp cutting detection device, the heddle frame and the reed. In this state, these members are transferred from the machine setting device to the loom.

On the other hand, the loom is provided with respective holding parts for holding respective members such as warp beams transferred from the machine setting device, and the members transferred from the machine setting device have these predetermined holding parts. Held in. As a warp beam holder which is one of the holding portions, for example, one shown in FIG. 4 is known. On the upper part of the warp beam supporting bracket 82 attached to the side frame 81 of the loom, a warp beam mounting recess 83 is formed, and a guide groove 84 connected to the recess 83 is horizontally formed. There is. The recess 83 is the shaft 86 of the warp beam 85.
The upper bearing 87 is supported, and the guide groove 84 guides the rolling of the bearing 87. A quarter-arc clamp member 88 is attached to the bracket 82 so as to be openable and closable. The clamp member 88 is fixed to the bracket 82 with a bolt 89. In this fixed state, the bearing 87 serves as the clamp member 88 and the recess 83 of the bracket 82.
And the warp beam 85 is supported by the loom.

Further, the loom is provided with a feeding motor 90 and a worm 91 connected thereto. When the warp beam 85 is supported by the loom, the worm wheel 92 and the worm 91 on the shaft 86 of the warp beam 85 mesh with each other. Then, by driving the delivery motor 90, a rotational force is transmitted to the warp beam 85 via the worm 91 and the worm wheel 92, the warp beam 85 is rotated counterclockwise, and the warp is delivered.

When a member such as the warp beam 85 previously supported by the machine setting device is transferred to the loom, first, the bearing 87 of the warp beam 85 is recessed on the bracket 82.
Move the device to the position where it engages with 3. Then, the clamp member 88 that has been standing by above is rotated clockwise to fix the clamp member 88 to the bracket 82 via the bolt 89. After that, the warp cutting detection device, the heddle frame, and the reed, which are supported by the machine setting device, are arranged at predetermined positions of the loom.

However, when the warp beam 85 is placed in the recess 83, the worm wheel 92 of the warp beam 85 meshes with the worm 91. At this time,
Since the loom is stopped, the worm 91 and the worm wheel 92 mesh with each other, so that the warp beam 85 cannot rotate independently. Therefore, when the warp cutting detection device or the heddle frame or the like is placed on the loom, the warp cannot be fed from the warp beam 85. That is, when the warp cutting detection device, the heddle frame, and the like are set on the loom, tension may act on the warp. At this time, if the warp cannot be fed out, it becomes difficult to set the warp cutting detection device and the heddle frame.

In order to prevent this, first, the warp cutting detector or the heddle frame or the like is placed at a predetermined position in a state where the warp beam 85 is floated to the extent that the worm wheel 92 of the warp beam 85 does not contact the worm 91. . Then, the warp beam 85 is lowered to move the worm wheel 9
The above problem can be solved by engaging 2 with the worm 91.

[0009]

However, in the conventional structure, as shown in FIG. 4, the concave portion 83 on which the warp beam 85 is placed is circular, and a projection projecting toward the machine tacking device is provided above the concave portion 83. Has been formed. For this reason, as shown by the chain double-dashed line in FIG. 4, when the warp beam 85 is floated from a predetermined position, the bearing 87 contacts the overhanging portion of the bracket 82. There is a problem in that there is a possibility that the warp cutting detection device, the heddle frame, or the like cannot be properly arranged because the parallelism becomes incorrect.

The present invention has been made by paying attention to such problems existing in the prior art. The purpose thereof is to make it possible to reliably transfer the members such as the warp beam 85 when the members are transferred from the machine setting device to the loom side.
