Device for depositing sheets for a printing machine

Abstract

A device for depositing sheets for a printing machine. The invention provides a device, which, while safely guiding sheets, is, at the same time, relatively complex and can still be configured in a largely open and accessible manner. The device is characterized by a transport path segment for the sheets, the path branching in the region of influence of a rotating transport member, whereby the transport member itself forms a part of the boundary of the transport path segment, and whereby an adjustable switch is provided in the branching region. The switch is used to enable a path for a sheet transported through the transport path segment in transport direction after a part of the transport path segment bordered by the transport member in order for the sheet to leave the region of influence of the rotating transport member, or to enable a path for a guiding deflection by the transport member acting as the deflecting member.

1 . Device for depositing sheets for a printing machine, characterized by a transport path segment for the sheets, said path branching in the region of influence of a rotating transport member, whereby said transport member itself forms a part of the boundary of the transport path segment and whereby an adjustable switch is provided in the branching region, said switch being used to enable a path for a sheet transported through the transport path segment in transport direction after a part of the transport path segment bordered by the transport member, in order for said sheet to leave the region of influence of the rotating transport member or to enable a path for a guiding deflection by the transport member acting as the deflecting member.  
   
   
       2 . Device as in  claim 1 , characterized in that the path, for leaving the region of influence of the rotating transport member, leads to a single-sheet deposit means, and the path, for a transport deflection performed by the transport member, leads to a stacker.  
   
   
       3 . Device as in  claim 1 , characterized in that the switch meshes in its respective position with guide elements for the sheet.  
   
   
       4 . Device as in  claim 3 , characterized in that the switch can be thrown by means of an electromagnet.  
   
   
       5 . Device as in  claim 1 , characterized in that the transport member is configured as an injection-molded component.  
   
   
       6 . Device as in  claim 1 , characterized in that the outer circumference of the transport member is provided with a coating, which exhibits a desired grip for the transport of sheets owing to a defined Shore hardness and which, due to sufficient recovery from deformation, excludes a permanent deformation.  
   
   
       7 . Device as in  claim 6 , characterized in that a silicon material is chosen for the coating.  
   
   
       8 . Device as in  claim 1 , characterized in that the transport member has a diameter greater than or equal to 200 millimeters.  
   
   
       9 . Device as in  claim 1 , characterized in that, on one of the branch paths, the transport member is followed by another rotating transport member preferably having essentially the same size, and that the sheets are routed in an essentially S-shaped path around these transport members.  
   
   
       10 . Device as in  claim 9 , characterized in that the transport path segment leading away from the transport member is configured as a transport path connection for another machine to be subsequently docked thereto.  
   
   
       11 . Device as in  claim 1 , characterized in that the device is configured as a module, thus permitting the direct successive connection of several of said essentially similarly configured modules in order to create a multi-branch transport path.
