Category: Industrial & Mechanical Engineering

Project: December 2004 – January 2005 (2 months)

Description

Further development and partial redesign of a software system for a cutting line of curtain fabrics in the textile industry. The application consists of a standard PC with touch screen for job acquisition and processing, a soft PLC that communicates with the PC via RS-232 interface, two servo drives with pulse-direction interface, as well as photoelectric switches and limit switches. A laser cuts the curtain fabric vertical and horizontal, whereby the PLC autonomously carries out the X-Y control.

Project: January 2003 – February 2003 (2 months)

Description

Development of an application program for Soft-PLC in C: The application consists of six (6) industrial sewing machines, whereby needle and gripper are not mechanically coupled but via two servo drives. The servos are controlled and monitored via a PLC that also handles thread monitors, material sensors and fault signals. The six PLCs are networked via CAN bus, one PLC serving as a master station. A display for operating the machine is connected to the master PLC via the CAN bus.

Description

Development of an application program for Soft PLC in C. The machine simultaneously sews two sides of a mop. It consists of a pneumatic gripping device, a feed drive and a puller drive; two servo drives each driving an industrial sewing machine, a thread chopper and a thread extractor. The drives are controlled by the PLC via the CAN bus (CANopen protocol) and the remaining actuators and sensors via digital inputs / outputs. The sewing machine is operated via a display that communicates with the PLC via the CAN bus.
