Mechatronic Applicator for Dispersion Adhesives
The article presents the operation and structure of a dispersion adhesive applicator dedicated for printing industry. Contrary to the currently used solutions in which the length of the glue layer is defined by the geometry of the glue roller, the original device enables free formation of the relation between the bonding area and adhesive-free areas. Based on the analysis of geometrical and time dependencies characterising the designed device, a mechatronic control system was developed to enable repeated glue application synchronised with the markers commonly used in printing industry and applied onto the paper. Constructed based on a programmable PLC controller, the system has control over all crucial technological parameters of the process (temperature, glue amount, beginning and end of the bonding area). The user-device communication is interactive, and therefore an additional user panel (touch-screen) is employed. The developed solution was used for applying dispersion adhesives in a technological line for producing multilayer ID cards with RFID labels.
