Device for detecting broken yarn through shaft frame and method for locating its address

Abstract

The invention relates to a method for locating address for plural controllers of a yarn breakage detector and the yarn breakage detector with address setting function. The yarn breakage detector is composed of a plurality of serially connected controllers corresponding to a plurality of yarn breakage sensors for each supporting member of a yarn feeding member, and a central processor for monitoring the yarn breakage in the whole creel apparatus and connected to the controllers in series. The central processor outputs a signal containing address information to the controller of the uppermost stream side. The uppermost controller recognizes / memorizes the own address based on the inputted signal, acquires the address information of the following downstream-side controller based on the inputted signal information according to a prescribed operation procedure, and outputs a signal containing the address information to the following downstream-side controller. Each controller successively sets the address to all following downstream controllers. The invention can successively automatically set address for each controller without setting address for other hardware such as DIL switch andso on.

Description

technical field [0001] The present invention relates to a method of setting addresses for a plurality of controllers of the yarn break detection device in a yarn break detection device included in a creel device, and to a yarn break detection device having an address setting function. Background technique [0002] In the preparation stage of warp beams used in looms and the like, yarns are drawn out all at once from a plurality of yarn supply bodies mounted on a creel device, and are wound around the warp beams by a winding device or the like. Among the many yarns drawn out from the creel device, even if one yarn breaks, the number of yarns wound on the warp beam will be insufficient. Therefore, in the winding process, it is necessary to Yarn detection Yarn break. In addition, when a yarn breakage occurs, the operator wishes to specify which yarn supply body the yarn breakage occurred in order to repair the yarn breakage. [0003] Therefore, a yarn breakage sensor is provi...

AI Technical Summary

Problems solved by technology

First of all (1) as the 100 described in the above example, the number of slave control devices installed on the creel device is very large, and it takes time and manpower to set addresses one by one.

(2) As far as the setting operation is concerned, since the operator needs to operate the DIP switches one by one, setting errors are prone to occur

(3) Since it is necessary to provide switches for address setting to all slave control devices, the structure of the device is complicated and the price is increased
