Abstract

A sheet-fed printing press has at least one coating assembly configured as a non-impact coating assembly. The sheet-fed printing press has at least one transport belt which extends, having at least one transport section of a circular path thereto, parallel to a transport direction along a partial region of a transport path provided for a sheet. At least one coating location of the at least one coating assembly is arranged along the transport section of the at least one transport belt. At least one printing head is arranged connected to at least one first frame of the at least one coating assembly. The at least one transport belt is arranged, connected to at least one second frame, via at least one deflection device and at least one radial bearing. The at least one first frame, apart from at least one installation surface which is different from the at least one first frame and the at least one second frame, is arranged in contact to the second frame at most via flexible connections.

First claim

The invention claimed is:

1. A sheet-fed printing press, including;
at least one sheet coating unit of the sheet-fed printing press and configured as a non-impact sheet coating unit, the at least one sheet coating unit including a transport path for sheets to be coated, the at least one sheet coating unit further including at least one sheet coating position configured as at least one sheet coating print head:
at least one first frame of the at least one sheet coating unit of the sheet-fed printing press, the at least one sheet coating print head being connected to the at least one first frame of the at least one sheet coating unit, the at least one first frame having first and second spaced lateral walls and at least one upper cross member and at least one lower cross member, which first and second spaced lateral walls and upper and lower cross members define an opening in the at least one first frame;
at least one conveyor belt for conveying sheets along the transport path in the at least one sheet coating unit of the sheet-fed printing press, the at least one conveyor belt having a circulation path, the conveyor belt circulation path including at least one sheet conveying section, along which at least one sheet conveying section the at least one sheet coating position is located, and which at least one sheet conveying section is parallel to a transport direction of sheets along a section of the transport path of the sheets to be coated, the at least one conveyor belt including at least one deflection means and at least one radial bearing, at least one portion of the at least one conveyor belt passing through the opening in the at least one first frame;
at least one second frame of the sheet coating unit of the sheet-fed printing press, the at least one conveyor belt being connected to the at least one second frame by the at least one deflection means and by the at least one radial bearing; and
at least one installation surface different from the at least one first frame of the at least one sheet coating unit and different from the at least one second frame of the at least one sheet coating unit and whereby, to decouple the at least one print head of the at least one sheet coating unit from possible vibrations induced in the at least one print head of the at least one sheet coating unit by one of the at least one conveyor belt and by the at least one deflection means of the at least one coating unit and from drives therefor, the at least one first frame and the at least one second frame have an absence of any rigid connection between each other, apart from their respective connections to the at least one installation surface, which at least one installation surface is different from the at least one first frame and from the at least one second frame, and by their non-rigid connection to each other through only one or more flexible connections.

2. The sheet-fed printing press according to claim 1 , wherein at least one drive of the conveyor belt is arranged, at least partially, one of directly and indirectly rigidly connected to the second frame.

3. The sheet-fed printing press according to claim 1 , wherein the at least one print head is arranged connected one of by at least one positioning device and by at least one other component to the at least one first frame.

4. The sheet-fed printing press according to claim 1 , wherein the at least one print head is connected one of directly and indirectly to lateral walls of the first frame and is located, at least partially, vertically above at least one section of the at least one conveyor belt.

5. The sheet-fed printing press according to claim 1 , wherein the at least one print head is configured as an inkjet print head.

6. The sheet-fed printing press according to claim 1 , wherein the at least one second frame is a frame of one of another unit and a module.

7. The sheet-fed printing press according to claim 1 , wherein one of the second frame and lateral supports of the second frame lie between lateral walls of the at least one first frame in a direction transverse to the transport direction of sheets.

8. The sheet-fed printing press according to claim 1 , wherein the at least one installation surface is at least one surface that supports the at least one first frame and the at least one second frame, and that also supports the at least one coating unit and the sheet-fed printing press, and wherein the at least one installation surface is a floor of one of a building and a component of a stable and low-vibration substructure.

9. The sheet-fed printing press according to claim 1 , wherein the second frame has at least two lateral supports spaced apart from one another with respect to a direction transverse to the transport direction of sheet, and one of wherein the at least one conveyor belt is arranged at least partially between the at least two lateral supports of the second frame with respect to the transverse direction, and wherein at least one of the at least two lateral supports is arranged connected, via at least one cross member of the second frame to at least another one of the at least two lateral supports of the second frame.

10. The sheet-fed printing press according to claim 9 , one of wherein the at least one cross member of the second frame is located at least partially vertically below at least one section of the at least one conveyor belt, and wherein the at least one cross member of the second frame is located at least partially vertically below at least a second section of the at least one conveyor belt, which is arranged at least partially vertically below a further section of the at least one conveyor belt, and wherein at least another cross member of the second frame is arranged at least partially vertically above at least one section of the at least one conveyor belt, wherein at least a further cross member of the second frame is also arranged, at least partially, vertically above at the least one section of the at least one conveyor belt, which at least one section of the at least one conveyor belt is arranged, at least partially, vertically above a further section of said at least one conveyor belt, and wherein at least one additional cross member of the second frame is arranged, at least partially, vertically above at least one section of the at least one conveyor belt and is arranged at least partially vertically below another section of the at least one conveyor belt.

11. The sheet-fed printing press according to claim 1 , wherein the one or more flexible connections are one of an interposition of at least one flexible component and/or an interposition of at least one flexible assembly.

12. The sheet-fed printing press according to claim 1 , wherein the one or more flexible connections are one of direct contacts and contacts imparted indirectly via other components.

13. The sheet-fed printing press according to claim 1 , wherein the one or more flexible connections are formed by at least one of flexible components and by at least one mechanically flexible assembly.

14. The sheet-fed printing press according to claim 1 , wherein the one or more flexible connections are at least one of supply lines for power and data and gas and gas mixtures and liquids and one of reversibly deformable bodies and assemblies that have deformable bodies.
