| 摘要 |
The invention concerns a device for applying patterns by means of screen print, particularly on ceramic plates, comprising a framework fitted with two tubular guides, with the following assemblies located as results from the technology: brake, small chain wheel, drive wheel, wedge wheel, also a squeegee guide and screen frame unit are seated at the right angle to the chain, and front and rear guides combined with the ramework, characterised in that the device is fitted with two independent drives, whereas one drive (ZN1) is connected with the drive wheel (8) of the chain (5), and the other drive (ZN2) is connected with the crank mechanism (32) of squeegee guide and screen frame unit (25), whereas the operation cycle of both drives (ZN1, ZN2) is forced by pulses from preferably five sensors (A, B, C, D, E) that react to the appearance of edges of the processed plates, whereas four of those sensors (A, B, C, D) are spaced along the front guide (21) and the rear guide (22) seated in the framework (1) in parallel to the chain (5), and the fifth sensor (E) mating with the encoder disk (34) seated on the second drive (ZN2) axle is located in the squeegee guide and screen frame unit (25), and the device is fitted with an auxiliary motor (S2) connected with wedge wheels (12) of wedge belts (13) that feed the plates.<IMAGE>
