GRR 117 automatic series glass edge cleaning machines are designed to prepare the edges of glass panes for subsequent gluing in the casement overlap. A cleaning felt strip soaked with cleaning liquid travels along the glass edges in a fully automatic fashion, thus removing dirt and fat residue. Rubberized drive rollers serving as supports ensure damage-free glass pane transport throughout the entire cleaning process.
Sequence of operations
For the purpose of cleaning, the glass pane moves through a cleaning portal. Depending on whether only one side or both sides of the pane are to be cleaned, the portal is equipped with three or six cleaning heads. The heads cleaning the lower edge of the pane are fixed at the front and at the back of the frame.
During the cleaning operation, the pane moves past the lower cleaning heads.
In order to enable the vertical sides of the pane to be cleaned, the pane is stopped with the start and end arms in the cleaning portal.
On the start or end arm, both cleaning heads move up on the pane cleaning.
The panes are cleaned with felt strips, which are sprayed with cleaning liquid at a freely selectable interval. The amount of cleaning liquid to be sprayed on can be dosed through the control system of the machine. After a freely selectable number of cleaning cycles, the dirty felt strip is cut off automatically, with a clean felt strip being provided. Each head comes with a drum holding the roll of felt strip, a felt strip feeding and cut-off device and a spray unit for the cleaning agent. The replacement of felt rolls is easy.
