Device for adjustment of the parameters for optimal piecing operations on a rotor spinning machine

摘要

The process and device for setting optimal piecing parameters in the spinning machine when changing batches includes entering and storing in a memory of a central machine computer spinning machine data relevant to the piecing operation. At the start of the piecing operation, the machine data is transmitted from the central machine computer to a microcomputer of a piecing device. The microcomputer contains a piecing program and a database of piecing parameters pertaining to the piecing process. An optimal set of piecing parameters is computed with the piecing program in the microcomputer. The microcomputer incorporates the spinning machine data and computes from the database an optimal basic set of piecing parameters. The optimal set of piecing parameters is displayed at an optical display unit associated with the microcomputer and can be manually adjusted.
