Punching/perforation machine

1. A punching/perforating machine ( 10 ) for generating a predefinable punching/perforation pattern in a material unit/web (M) supplied in a transport direction (T), comprising:

a punching/perforation tool ( 12 ) having

a tool upper part ( 12 . 1 ), which is movable in a stroke direction (H) and which has a plurality of stamping punches/perforating needles ( 16 ) which are arranged in a predefined grid in a transverse direction (Q) and which are movable by a pressure beam ( 36 ) which is operatively connected via a control device ( 30 ) to a drive unit ( 18 ) for generating a punching/perforation stroke (H), and

a stationary tool lower part ( 12 . 2 ), the stationary tool lower part ( 12 . 2 ) being a female die,

wherein the material unit/web (M) is supplied between the tool upper part ( 12 . 1 ) and the stationary tool lower part ( 12 . 2 ),

wherein means ( 70 , 72 ) for generating a simultaneous relative movement of the material unit/web (M) relative to the punching/perforation tool ( 12 ) to a predefinable extent both in the transport direction (T) and in the transverse direction (Q) are present, such that the material unit/web (M) is positionable, prior to each punching/perforation stroke (H), in an individual predefinable position relative to the punching/perforation tool ( 12 ).

2. The punching/perforating machine as claimed in claim 1 , wherein the means ( 70 , 72 ) comprise

a first drive unit ( 70 ), which brings about a movement of the material unit/web (M) in the transport direction (T), and

a second drive unit ( 72 ), which brings about the movement of the material unit/web (M) in the transverse direction.

3. The punching/perforating machine as claimed in claim 2 ,

wherein the first drive unit ( 70 ) and the second drive unit ( 72 ) are each formed as a servomotor.

4. The punching/perforating machine as claimed in claim 2 ,

wherein the drive units ( 70 , 72 ) are connected via coupling members to the material unit/web (M).

5. The punching/perforating machine as claimed in claim 1 ,

further comprising a memory device ( 40 ), in which data for a geometry of the punching/perforation pattern with respect to position and diameter is stored,

wherein the control device ( 30 ) is communicatively connected to the memory device ( 40 ),

wherein the control device ( 30 ) is operatively connected to a control block ( 14 ) of the stamping punches/perforating needles ( 16 ) for actuation/activation/deactivation of the stamping punches/perforating needles ( 16 ) during a punching/perforating operation,

wherein the control device ( 30 ) is communicatively connected to the means ( 70 , 72 ) for generating a simultaneous relative movement of the material unit/web (M) and

wherein the control device ( 30 ) initiates the corresponding activation of the means ( 70 , 72 ) in dependence on the data stored in the memory device ( 40 ).

6. The punching/perforating machine as claimed in claim 1 ,

wherein the punching/perforation tool ( 12 ) comprises stamping punches/perforating needles ( 16 ) having different diameters.

7. The punching/perforating machine as claimed in claim 1 , further comprising:

a control block ( 14 ), which comprises piston-cylinder units whose movements during the punching/perforation stroke are individually actuable via the control device ( 30 ) and are individually assigned to each stamping punch/each perforating needle ( 16 ); and

a blocking slide ( 22 ), which is connected in each case to a corresponding piston rod ( 20 ) of the piston-cylinder unit, wherein the blocking slide ( 22 ) is displaceable into an activation or deactivation position by the movement of the piston rod ( 20 ),

wherein, in the activation position, the blocking slide acts directly or indirectly on the stamping punch/the perforating needle ( 16 ) during execution of the stroke (H), and

wherein, in the deactivation position, the blocking slide does not exert any action on the stamping punch/the perforating needle ( 16 ),

such that, in the activation position of the blocking slide ( 22 ), the blocking slide ( 22 ) acts on the stamping punch/perforating needle ( 16 ) during the stroke (H) and a perforation is carried out and, in the deactivation position of the blocking slide, no punching/perforation of the material unit/web (M) is effected.

8. The punching/perforating machine as claimed in claim 7 ,

wherein the piston-cylinder unit is formed as a double-acting piston-cylinder unit having a first pressure chamber ( 28 ) and a second pressure chamber ( 32 ),

wherein a first pressure (P 1 ) is applied permanently to the first pressure chamber ( 28 ) via the control device ( 30 ) and has the effect that the blocking slide ( 22 ) is located or retained in the deactivation position and,

when carrying out punching or perforation, the control device ( 30 ) applies a second pressure (P 2 ), which is higher than the first pressure (P 1 ), to the second pressure chamber ( 32 ) when activated, such that the blocking slide ( 22 ) moves out into the activation position and,

as a result, during the stroke (H), this movement is transmitted to the associated stamping punch/perforating needle, such that punching or perforation of the material unit/web (M) is carried out.
