Problems solved by technology

[0003] The disadvantage of this press transport system is that the newly printed surface is contacted when the individual sheets are removed from the transport table
The disadvantage of this case is that a non-printing margin must be left free for the transfer gripper
That is, individual sheets cannot be fully printed

Embodiment Construction

[0023] Figure 5 A machine according to the invention for conveying flat elements is shown, for example a sheet printing machine 100 in which a sheet 1000 from a feeder 2 is printed in a printing station 1 and thereafter in a take-up Collected in container 3. In the region of the printing station 1 , the transport system 9 moves the sheets along the transport path and prints them there. While the individual sheets 1000 are being transported in the transport direction T, they lie flat on the transport table 4 . The upper side of the individual sheets 1000 is thus freely accessible and can be printed in the printing station 1 by a printing head (not shown in detail). The driving device 5 moves the conveying table 4 on a revolving track. For this purpose, the drive device 5 has on the one hand a chain drive 6 and on the other hand a toothed belt 10 driven by a servomotor, wherein the latter (toothed belt 10) moves the conveyor table 4 along the The subsection of the conveyor ...

Abstract

The invention relates to a machine (100) for transporting sheet-like elements (1000) having a transport system (9), wherein the transport system (9) comprises a plurality of driven, along a closed guide track (7) revolving transport tables (4) has, and this with a support surface (13) for supporting the transported flat elements (1000) are executed. According to the invention, a respective transport table (4) hinged flaps (11) and the transport system (9) a discharge comb (12) for transferring flat elements (1000) from the transport tables (4) on the discharge comb (12), wherein the support surface (13 ) and the discharge comb (12) at least intermittently mesh with each. Thereby a safe and damage free removal of a sheet-like member (1000) from the bearing surface of a respective transport table (4) is made possible in an advantageous manner.

Description

technical field [0001] The invention relates to a machine for conveying flat elements. Background technique [0002] The use of digital printing presses is known for printing sheets made of paper, cardboard or cardboard in small runs or with individual printing engines. In the case of printing the sheets using inkjet heads, the individual sheets are moved under the inkjet heads with a minimum distance by a transport system. Conveyor systems are known: conveyor belts, for example in the form of suction belts; rotating drums, so-called jetting drums. From US 8,579,286 B2 comes a variant embodiment of the conveying system: the sheets are placed flat on the conveying table (so-called tray, tablet) by the sheet feeder, wherein the tray is moved past the printing head, so that the corresponding The upper side of a sheet lying flat on the tray can be printed by the printhead. After the printing process has been completed, the sheets are removed from the tray again. In this case...
