Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support device for a heddle frame in a loom, and more particularly to a pair of first ropes for transmitting a driving force and a spring action against the driving force for opening a warp. The present invention relates to a heald frame supporting device in a loom having a heald frame supported by a pair of second ropes.

[0002]

2. Description of the Related Art Conventionally, in order to open a warp, a heald frame is supported by a pair of first ropes for transmitting a driving force and a pair of second ropes for transmitting an action of a spring against the driving force. In a heddle frame support device in a loom, a load is repeatedly applied to each rope, and since each rope is bent and guided by a guide roller, it stretches over time and the force of the spring acts. It weakens the height of the heddle frame and weakens the heddle frame, making it impossible to form a regular opening and adversely affecting the weft insertion. In particular, when the loom speeds up, as in recent years, the rope tends to stretch due to the increase in inertial force, and a difference between the actual opening amount and the set opening amount easily occurs. This has led to an increase in mistakes.

Therefore, in the conventional heald frame supporting device for such a loom, it is essential to adjust the height position of the heald frame, and the hooks provided on the extension parts of the side stays on both sides of the heald frame. The first and second ropes are engaged with the part, and a turnbuckle is interposed in the middle of the first rope,
By adjusting the length of the rope, the height position of the heddle frame can be adjusted (for example, Japanese Utility Model Laid-Open No. 62-203277), and the adjustment bolt can be inserted into the connecting body attached to the outer surface of the side stay. A nut to be locked to the upper surface of the connecting body is screwed to one end of the adjusting bolt, a first rope connected to the other end of the adjusting bolt is connected, and the nut is rotated to rotate the nut. The height position of the heddle frame is adjusted by changing the screwing position (see Japanese Utility Model Laid-Open No. 61-187384).

[0004]

However, the operation of the turnbuckle interposed in the middle of the first rope is extremely poor in workability, and in the case disclosed in Japanese Utility Model Laid-Open No. 61-187384. , The bolts are screwed from the side stays to the connecting body, and both are fastened and fixed.
There is a problem in that it is inconvenient to attach and detach the heddle frame when passing through.

The present invention has been made in order to solve such a problem of the conventional heald frame connecting device in a loom, and enables easy attachment / detachment of the heald frame and adjustment of the height position of the heald frame. It is an object of the present invention to provide a heald frame supporting device in a loom that is simple.

In order to achieve the above object, the present invention provides
In a heddle frame connecting device in a loom having a heddle frame supported by a pair of first ropes transmitting a driving force and a pair of second ropes transmitting a function of a spring against the driving force,
A block having a first support part that constitutes a holding means for holding the first rope adjustably, and a second support part to which the second rope is fixed, and the block and the side side stays of the heddle frame. A clamp for tightening together is provided, and a protrusion is provided on one of the block and the side stay, and a recess that engages with the protrusion is provided on the other.

[0007]

Operation: A block having a first support portion which constitutes a holding means for holding the first rope adjustable and a second support portion to which the second rope is fixed, and the block and the side stay of the heddle frame. A clamp for tightening together is provided, and a protrusion is provided on either one of the block and the side stay, and a recess for engaging with the protrusion is provided on the other side. The heddle frame can be removed from the block by removing it toward the rope (the same applies to the support device on the opposite side of the heddle frame), that is, the heddle frame can be removed from the loom.

In order to attach the heddle frame, the side stays on both sides of the heddle frame are made to face the block, and the recesses of one of the side stays of the heddle frame and the block and the protrusions of the other are engaged. Then, the clamp is lowered to the tightening position, and the side stay and the block are integrally tightened with the tightening screw. Then, the working length of the first rope can be adjusted by the holding means constituted by the first supporting portion, and thereby the height position of the heddle frame can be adjusted.
