Description

Weft transport unit for rapier looms

The present invention relates to a weft conveying unit for a raffir loom, and more particularly, a hinge portion of a hook swinging so that the weft is gripped at a position close to the pressing block, and a connecting rod that adds elasticity with a hook is a pliers or It relates to a weft transfer unit for a rapier loom that can prevent the weft from shifting or detaching from the pressing block during transport as it is possible to grip the weft with quick operation and strong grip by connecting it with a multi-joint lever structure like an excavator. .

In general, in the case of fabrics (fibers) using flat yarn or film yarn having a predetermined width and thin thickness as weft yarns (weft yarns), since the weft yarns must be transferred with a strong force, the weft yarns are directly transported. Weaving on a peer loom.

This flat-use rapier loom can be largely divided into a body part for opening and moving the warp yarns continuously arranged back and forth in a predetermined pattern, and a weft part for transporting weft yarn between the warps.

Here, the weft part is composed of a conveying unit (carrier) that directly grips the weft and reciprocates between the warps, and a guide unit that delivers the supplied weft to the conveying unit.

The conventional conveying unit is configured with a pressure plate that swings up and down so that the transferred weft yarn is gripped.

And the pressure plate is equipped with a rod-shaped hook that induces a vertical swing motion by a pressing unit (opener).

That is, the hook is mounted as a hinge on the body of the conveying unit like a seesaw, a pressing plate is mounted on one side of the hinge, and a pressing part contacting the pressing unit on the other side.

Here, a spring is interposed at the lower end of the pressing unit to apply an elastic force so that the pressing plate grips the weft yarn.

However, since the hinge (full point) of the hook is located in the middle part relatively far away from the pressing plate, there is a problem in that the elastic force of the spring for stably gripping the weft yarn is insufficient.

Of course, the hinge of the hook may be formed in a position close to the pressing plate, but in this case, there is a problem in that the pressing range is significantly increased compared to the swing range of the pressing plate.

In addition, a spring having strong elasticity may be applied, but too strong elasticity may cause damage to the pressing part and noise.

Moreover, since it is impossible to adjust the elastic force, there is a problem that the spring needs to be replaced according to the thickness or material of the weft yarn.

On the other hand, the conventional conveying unit had to be equipped with a pressing unit on both the left and right sides of the loom to hold the weft on one side and then release the weft from the other side to return.

That is, there are disadvantages in that the overall speed of the loom is lowered and it is difficult to control because the conveying unit has to perform a pressing operation in a completely stopped state.
