Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a wire mesh loom which is woven by using a wire having a crimp (corrugation) in order to weave a fine mesh.

[0002]

[Prior art]

 In the method of bending and deforming a wire using only straight wefts at the time of weaving, there is a limit to the deformation of the wire, so the minimum mesh size is determined according to the diameter of the wire used. It is impossible to make wire mesh with a finer mesh than this. In addition, in the wire mesh near the limit, the wire is subjected to excessive force during weaving, so the woven wire mesh has a deformed habit and is not flat.

In order to solve this problem, a weaving method in which a crimp is formed in advance on a latitude line and the crimp is woven has been already practiced. That is, prior to the weaving work, a crimp forming machine is used to crimp the latitudinal lines according to the weaving width, and the latitudinal lines are cut to match the weaving width. It will be weaved.

[Problems to be solved by the device]

However, in the conventional method of crimping the parallels in advance, it is difficult to automate the parallels insertion work, and if this is done manually, the work cost becomes high, and if the mechanization is attempted, the equipment will not be installed. There is a problem of high cost.

In view of such a point, the present invention attaches a crimp forming device to a loom, and weaves the weft lines while crimping them, thereby performing efficient weaving work with simple equipment. It is intended to provide the wire mesh loom.

[0006]

Means for Solving the Problems A technical means of a wire mesh loom of the present invention is a crimp forming device including a pair of toothed rollers provided at a weft insertion position of a loom main body, and a crimp forming device of the crimp forming device. It is equipped with a drive unit, a rapier with a parallel line metal fitting at the tip, and a drive unit for the rapier.The two drive units operate in synchronization, and only when the rapier moves backward with the line of the parallel line. The crimp forming device is activated to crimp the latitude line and send it out.

[0007]

[Action]

 In the wire mesh loom of the present invention, a crimp forming device is provided at the weft insertion position of the loom body, and the latitude line is sent out to the opening of the meridian while being crimped. The rapier moves forward and backward in the width direction inside the opening of the meridian. The tip of the rapier is equipped with a clasp, and when it moves to the most forward position, it grasps the tip of the latitude line and then moves backward with the latitude line held.

The drive device of the crimp forming device and the drive device of the rapier operate in synchronization with each other. Therefore, when the rapier moves backwards along the latitude line, the crimp forming device operates to apply the crimp to the latitude line and send it out. In other words, the latitudinal line has its tip pulled by a rapier, and is fed from the rear by a crimp forming device and inserted into the opening of the meridian line.

【Example】

 The wire mesh loom of the present invention will be described with reference to the embodiments shown in the drawings. Reference numeral 1 is a crimp forming device, which is attached to the weft insertion position of the loom body. The crimp forming device 1 comprises a pair of gear-shaped pressing rollers 2 and 3 which are provided in an opposed manner, and the lower roller 2 is fixed in position and is on the driving side. The upper roller 3 is movable in position, and a pressing force is applied from above. The latitude line A is extended so as to be caught between the rollers 2 and 3. When passing between the rollers 2 and 3, the latitude line A is deformed by the tooth profile of the rollers 2 and 3 and is sent out in a crimped state.

Reference numeral 4 is a drive device for the crimp forming device 1, and 5 is a rack gear, which is movable in the longitudinal axis direction. A pinion 6 is engaged with the rack gear 5 and rotates as the rack gear 5 moves. The rotation of the pinion 6 is transmitted to the roller 2 via the bevel gear mechanism 7, the one-way clutch 8 and the belt transmission mechanism 9. The reason why the one-way clutch 8 is used is that only forward rotation is transmitted. Therefore, even if the rack gear 5 reciprocates, the roller 2 rotates only in the forward direction and the rack gear 5 moves in the reverse direction. When the roller 2 is turned on, the roller 2 is stopped.

Reference numeral 11 is a lever, and 12 is a lever shaft. The tip of the lever 11 and the rack gear 5 are connected to each other. Therefore, when the lever 11 rotates, the rack gear 5 interlocks and moves in the longitudinal axis direction. Reference numeral 13 is an eccentric cam, and 14 is a cam floor. The cam floor 14 is supported by a lever 15 and is connected to the lever 11. The eccentric cam 13 is attached to the crankshaft 16 of the loom body. An opening movement device (not shown) is connected to the crankshaft 16, and the meridian is moved in accordance with the rotation of the crankshaft 16.

Reference numeral 20 is a rapier, and a knurling metal fitting 21 is attached to the tip thereof. The rapier 20 is moved forward and backward by a drive device 19. 22 is a drive gear, and the rapier 20 is provided with perforations that engage with the teeth of the gear 22. A flexible material is used as the material of the rapier 20, and the rear part is bent when the rapier is retracted.

Reference numeral 23 is a bevel gear mechanism, 20 is a pinion, 25 is a rack gear, and 26 is a lever. By the rotation of the lever 26, the drive gear 22 is repeatedly rotated, and the rapier 20 is moved forward and backward. The lever 26 is attached to the lever shaft 12 and moves integrally with the lever 11.

Next, the operation of the device will be described. When the loom is started, the crankshaft 16 rotates and the meridian is opened. Further, the eccentric cam 13 rotates as the crankshaft 16 rotates, the cam floor 14 moves up and down, and this is transmitted to the lever 11, whereby the lever 11, the lever shaft 12, and the lever 26 repeatedly rotate. Then, the movements of the levers 11 and 26 are transmitted to the rack gears 5 and 25, and the roller 2 and the drive gear 22 rotate. When the roller 2 rotates, the latitude line A is crimped and sent out. Further, when the drive gear 22 rotates, the rapier 20 is moved.

Since the operations of the crimp forming device 1 and the rapier 20 both depend on the rotation of the crankshaft 26, both operations are synchronized. That is, when the crimp forming device 1 is stopped, the rapier 20 moves forward, and the jaw fitting 21 of the rapier 20 holds the tip of the latitude line A at the most forward position. Then, at the same time as the rapier 20 begins to retreat, the crimp forming device 1 also operates, and the crimp is attached to the latitude line A to send it out. In this way, the latitudinal line A has its tip pulled by the rapier 20, is fed by the crimp forming device 1 from the rear side, and is inserted into the opening of the meridian.

When the rapier 20 reaches the final retracted position, the crimp forming device 1 also stops. Then, it is beaten, the lacing metal fitting 21 releases the end of the latitude line, and the rear end of the latitude line is cut. Next, the opening of the meridian is changed, and the rapier 20 starts to move forward to move to the next weaving operation.

The wire mesh loom of the present invention is not limited to the above embodiment, and can be automatically modified within the scope of the claims for utility model registration. In particular, the structure of the crimp forming device 1, the structure of the driving device of the crimp forming device, the structure of the rapier, and the structure of the rapier driving device can be freely selected as long as they can achieve similar functions. .

[0018]

[Effect of device]

 In the wire mesh loom of the present invention, the crimp forming device is attached to the main body of the loom and the parallel lines are inserted while forming the crimp, so that the work is rational, and the wire mesh can be woven efficiently. Further, the insertion of the latitude line is performed by pulling the tip with a rapier and feeding from the rear by a crimp forming device, so that the insertion of the latitude line is extremely smooth and the insertion operation time can be shortened.
