Abstract

The invention discloses an automatic weft finding device for a rapier loom. The automatic weft finding device comprises a weft sensor, a warp let-off mechanism, a reeling mechanism, a fluffing mechanism, an opening mechanism and a controller. The warp let-off mechanism, the reeling mechanism, the fluffing mechanism and the opening mechanism are provided with four variable frequency motors, respectively. The input end of the controller is connected with the weft sensor. The output end of the controller is connected with the four variable frequency motors; the controller is further connected with a stack storage. The invention further discloses an automatic weft finding method for the rapier loom. If weft breakage occurs, weft finding is performed at low equipment speed through a reversing program. The automatic weft finding device and method has the advantages that the defects of the prior art can be overcome, the structure of the rapier loom is simplified, and failure rate is reduced.

Description

technical field

[0001] The invention relates to the technical field of textiles, in particular to an automatic weft-seeking device and method for a towel rapier loom. Background technique

[0002] During the operation of the rapier loom, weft breakage will occur. In the prior art, a weft-seeking gear box is generally used for weft-seeking operation; in addition, Chinese invention patent CN101368314B discloses a method of using an electronic weft-seeking mechanism for automatic weft-seeking. No matter which method is used, the warp let-off mechanism, take-up mechanism, and raising mechanism are all fixed, and the opening mechanism performs reverse weft-seeking. This method requires additional complicated subsidiary mechanisms, and in the process of re-spinning It is prone to flower deformation and incompleteness. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide an automatic weft-seeking device and method for a ra...

Embodiment Construction

[0024] The standard parts used in the present invention can be purchased from the market, and the special-shaped parts can be customized according to the instructions and the accompanying drawings. The specific connection methods of each part adopt mature bolts, rivets, welding in the prior art , pasting and other conventional means, no longer described in detail here.

[0025] refer to Figure 1-5 A specific embodiment of the present invention includes a weft sensor 1, a let-off mechanism 2, a take-up mechanism 3, a raising mechanism 4, and an opening mechanism 5, and also includes a controller 6, a warp let-off mechanism 2, a take-up mechanism 3, and a raising mechanism 4. The opening mechanism 5 is respectively provided with a variable frequency motor 7, the input end of the controller 6 is connected with the weft yarn induction sensor 1, the output end of the controller 6 is respectively connected with four variable frequency motors 7, and the controller 6 is also connecte...
