Abstract
In order cost effectively and in spite of the lowest possible expenditure on construction to permit the logical provision of printing plates of different types and sizes for an extremely wide range of printing plate exposers, in an apparatus for loading and/or unloading an exposer, in particular a drum exposer, with printing plates, having a suction means comprising at least one sucker plate and at least two suction heads connected to a vacuum system for picking up printing plates, in particular thermal printing plates, and a pivoting device for pivoting the suction means, it is proposed that the sucker plate be constructed in the form of a cylindrical segment and the suction means be pivotable about an axle which is arranged substantially parallel to the axis of the cylindrical segment.
Claims38
An apparatus for loading and/or unloading an exposer (3), in particular a drum exposer (3), having printing plates (3) with
- a suction means (10, 11), comprising at least one sucker plate (10) and at least two suction heads (11) connected to a vacuum system, for picking up printing plates (7), in particular thermal printing plates,
- a pivoting device for pivoting the suction means (10, 11),
- wherein the sucker plate (10) is constructed in the form of a cylindrical segment and
- the suction means (10, 11) can be pivoted about an axis which is arranged substantially parallel to the axis of the cylindrical segment.
A method of loading and/or unloading an exposer (3), in particular a drum exposer (3), with printing plates (7) by means of an apparatus which comprises a suction means (10, 11) comprising at least one sucker plate (10) and at least two suction heads (11) connected to a vacuum system to pick up printing plates (7), in particular thermal printing plates (7), having one or more of the steps in which
- a printing plate (10) is picked up by the suction means (10, 11),
- is inserted into an exposer (3),
- is removed from the exposer (3) and
- is transferred to an output ramp (14), and
- an intermediate paper is removed
- wherein
- the sucker plate (10) is constructed in the form of a cylindrical segment,
- the suction means (10, 11) is fixed to arms and
- the suction means (10, 11) is moved by means of a pivoting movement of the arms (13).
