Automatic spray system for mixed production

Products are conveyed to the machine on a conveyor belt in mixed-mode operation. There, they are identified by barcode and weighed. The weight (quality characteristic) is written to a database together with the barcode. Based on the barcode, the manufacturing parameters are read from a database and the 8 axes are positioned to achieve an optimal spray pattern.

Workflow:

  • Transport and identification of the product (barcode)
  • Weighing the product and sending the weight to the QM database
  • Reading the manufacturing parameters from the production database
  • Positioning the 8 axes according to manufacturing parameters
  • Spraying the product

Technical data:

  • Controller: Simatic S7-315 PN/DP
  • SQL4Connector V2.x
  • Connection to 3 databases (ERP production database, recipe database with manufacturing parameters, quality database)

Note:

These applications are examples intended to demonstrate the possibilities of a PLC/SQL database connection. Modified solutions are always possible. For data protection reasons, images and process-specific details have been omitted. However, we are happy to answer any questions.

High-speed test stand for car tires (retrofit)

A new controller (Siemens Simatic S7) was set up in conjunction with a measurement data acquisition system on an existing customer high-speed test stand (up to 400 km/h) for passenger car tires. Various test orders are read from an ERP system and stored in a separate SQL database. From there, the test orders can be loaded into the controller and processed.
