Loom control - uses external memory card to monitor the data input from the computer

摘要

A process to regulate the drive on a loom, which is provided with a computer and control data from a memory device to regulate the machine. There is also a control panel and keyboard to feed in the data, and an external memory. When data being fed in to the computer at the control panel is not supported by the data from the external memory, the loom does not function. The central computer (Ce,Cg) is connected to a control panel (20e,20G) by means of which the loom can be set up to weave a certain fabric , having width, density, construction, controlled from the data supplied via the keyboard to the computer, and through the interfaces (F) to the other controls (Cs,Cd,Cr,Cy) to the let-off motor (15) healds (5) slay (6) weft insertion (16,17) to weave from the beam (2), and to the cloth take-up roller (8,9) on to the roll (10). Direct from the computer is a control for synchronisation and drive from the motor (M) to the mainshaft. ADVANTAGE - The loom cannot be operated without the external memory card. Incorrect data at the keyboard will be suppressed by the memory card.
