The polishing machine consists of a chain conveyor whose links are small desks equipped with revolving plates that can move along a linear track. 5 upper positions are technological ones (1 feeding position, 3 polishing positions and 1 removing position). The desks return back below to the feeding position from the removing position. The base of the machine consists in a steel construction. The positions are moved with a servomotor and transmission. All 5 upper positions are equipped with their own servomotor driving mechanisms for turning the plates. In the feeding and removing positions the article is turned appropriately to the handling equipment. In the polishing positions the article rotates in front of the burner. When moving the positions, the driving mechanisms of the plates are disengaged as they are swung away with a pneumatic cylinder, and the revolving of plates is mechanically locked. All three working positions have their own linear servomotor drive approach of burners. The control system enables to couple electronically the burner approach and revolving the plates, so that the burner can copy non-cylindrical shape of the article. Cylindrical articles can be polished after adjustment of the burner approach to the article diameter. The machine is shielded against scrapped glass and heat with stainless tin. The system of burners depends on a type of glass material and the size of glass articles. The articles can be cooled with airflow coming from outside or through the desk centres. The control system enables to set the jogging parameters of the machine and revolving the plates, to adjust the burner approach both for cylindrical and non-cylindrical article shapes, to create the electronic curve in order to follow the surface of non-cylindrical article shapes, and to switch the burner valves and cooling on and off. The main parameters of the machine can be changed during operation and the change is realized in the next cycle. The parameters can be stored as a recipe for the same type of glass product. The visual control enables you to show the data on the screen, including the timing of individual valves. The control systems of the machine and the whole line are equipped with inputs and outputs used for connection with the control systems of adjacent technological equipment (for example, pressing machine, annealing oven, etc.).
