Abstract
A blade is used to cut through a film between the panes of laminated glass in the area of a gap produced in the laminated glass the blade is provided on a holding device and can move along the gap. The holding device includes swiveling carrier on which there is a holding part for the blade with a vertical adjustment capacity. The blade is first placed next to the gap on the top of the top pane of the laminated glass. The vertical alignment of the blade is ascertained with a rule for determining the thickness of the laminated glass. Then the holding device is adjusted by a motor such that the blade falls into the gap. When a sufficient immersion depth of the blade into the gap is ascertained via the rule, the film is cut.
Claims21
Device for cutting through plastic films in laminated glass, comprising:
- an axle;
- a holding device mounted to swivel about the axle;
- a blade connected to the holding device and which is swivelable about the axle, said axle being parallel to a gap between two parts of a laminated glass, said blade being movable along the gap;
- and
- a drive for swiveling the holding device and the blade around the axle so that the blade moves transversely across the glass from a first position on the glass to a second position in the gap,
- wherein a holding part which bears the blade is vertically adjustable relative to a carrier which is suspended pendulous on a base plate of the holding device, relative to the carrier.
A process for cutting through plastic films in laminated glass using a blade, comprising the steps of:
- scratching top and bottom panes that together form two panes of laminated glass;
- breaking the two panes of laminated glass to form two parts;
- pulling the two parts of the laminated glass apart to open between the two parts of the laminated glass a gap in which a film which is located between the two panes of laminated glass lies freely;
- placing the blade next to the gap on the laminated glass;
- acquiring a location of the blade which has been placed on the laminated glass;
- determining from the location of the blade, a thickness of the laminated glass;
- determining a required penetration depth of the blade into the gap between the part of the laminated glass from the thickness of the laminated glass;
- and
- moving the blade transversely to a lengthwise extension of the gap between the two parts of the laminated glass in a direction towards the gap until the blade reaches the area of the gap;
- moving the blade into the gap;
- moving the blade along the gap to cut through the film;
- monitoring the penetration depth of the blade into the gap between the parts of the laminated glass.
