In particular, the invention has for its object to provide an apparatus and a method for treating substrates, which has an improved flexibility.

This object is achieved by an apparatus and a method, which are formed according to the features of patent claims 1 and 14.

The advantages that can be achieved with the invention are that an effective and / or secure separation of substrates into at least one waste part and at least one benefit while minimizing the required mechanical engineering effort is provided.

In an embodiment of the invention, it is particularly advantageous that the separating device treats already processed substrate, in particular separates into at least one waste part and at least one utility, the substrate processing its working parts by means of cutting rolls, which are effective in the cylinder gap of two of the separating rolls, in particular by cutting, punching , Grooves or perforations. The realization of the separation, which is also referred to as breaking, on the one hand, and of the processing, on the other, at different locations, increases the functional stability of the device for treating substrates.

Of particular advantage is also that by the formation of two air supply means for independent supply of first and second openings in conjunction with the switchability between Saugluftversorgung and a Blasluftversorgung a secure transport of waste parts and / or benefits and a safe release takes place at the designated locations.

In the case of a device for treating substrates with a gripper system for fixing the leading edges of sheet-shaped substrate, which is designed as a suction pad system, it is particularly advantageous that substrate sheets or lattice parts called lattice can be safely transported until release at the designated locations he follows. The suction pad system is comparatively simple in comparison to mechanical gripper systems, in particular clamping grippers. The formation of the suction pad system for register accurate transport can advantageously be omitted. In the latter device, it is furthermore particularly advantageous that the means for fixing the elevator is associated with the suction pad system, which includes the opposite case. This advantageously ensures that the number of moving parts is kept to a minimum. With minimal space requirements, the functions of fixing the elevator and holding the leading edges of the sheet-like substrate or grids are realized in a simple manner and also functionally stable. In a preferred embodiment of the invention, the suction air required for operating the suction pad system already rests against the transport cylinder and can also be advantageously used for holding waste parts and / or use on the lateral surface of the transport cylinder.

The latter applies in particular when the conveyor belt is a suction belt. In the case of the latter device, it is furthermore particularly advantageous that the transfer of waste parts or benefits from the transport cylinder to the conveyor belt is assisted by the application of blown air to the outer surface of the transport cylinder, ie in particular at the openings of the elevator fixed on the transport cylinder. It is also advantageous if the transfer of waste parts or benefits from the transport cylinder to the conveyor belt is effected solely by the application of blowing air to the lateral surface of the transport cylinder and the conveyor belt is not formed with suction-air-exposed openings, ie as a suction belt.

In the case of a device for treating substrates with a separating device comprising a transport cylinder and a stripping cylinder associated with the transport cylinder to which a circulating conveyor belt is assigned, there is an advantage, in particular, in the flexible usability of the device. If the conveyor belt is directly associated with the breakout cylinder and forms a transfer point or a transfer area with the breakout cylinder, in particular in the form of a tangent point or a wrap angle, the conveyor belt can advantageously assist the removal of the waste parts or benefits. The latter applies in particular when the conveyor belt is a suction belt. In the case of the last-mentioned device, it is furthermore particularly advantageous that the transfer of waste parts or benefits from the breakout cylinder to the conveyor belt can be achieved by applying blowing air to the jacket surface of the breakout cylinder, ie. H. in particular at the openings of the fixed on the transport cylinder elevator is supported. It is also advantageous if the transfer of waste parts or benefits of breakout cylinder is effected to the conveyor belt solely by the application of blowing air to the lateral surface of the transport cylinder and the conveyor belt not openings with suction air, d. H. as a suction belt is formed.
