A New Automatic Cocoon Filament End Picking Machine

A proposed method for filament end groping and picking operation

Abstract

In order to obtain the best method for groping and picking operation of cocoon filament ends, the problem was analysed and discussed from three different view points: (1) the unit quantity of the cocoons being processed, (2) the processing method, and (3) the unit processing time.
The results obtained were as follows:
(1) The unit quantity of cocoons being processed. The working efficiency of both groping and picking operations with a single cocoon was found better than that with a large quantity handled in a single operation.
(2) The processing method.
In both groping and picking operations, the cocoons to be processed were fed continuously toward the stationary groping brush and picking hook. In this manner, the working sequence was made continuous and simultaneously increased its efficiency.
(3) The unit processing time.
In both groping and picking operations, each working time should be performed within a fixed period which allows an optimum length of the filament to be picked, thereby preventing the cocoon from being floated during the operation.
