The invention is based on the object of creating a machine arrangement with several processing stations each for processing arcuate substrates, this machine arrangement having a device for the sequential transport of individual arcuate substrates, each with a gripper carriage moved along a movement path, this device further processing the transported ones in register Substrates guaranteed by their high positional precision.

The object is achieved according to the invention by the features of claim 1.

The respective dependent claims show advantageous configurations and / or developments of the solution found.

The advantages that can be achieved with the invention are in particular that, despite the use of a chain conveyor, further processing in register is guaranteed for the transported substrates due to their high positional precision.

It is also advantageous that a hybrid machine arrangement processing sheet-shaped substrates, preferably a hybrid printing machine, is formed which has the high productivity of a conventional, e.g. B. in an offset printing process or in a flexographic printing process or in a Screen printing process printing printing device or a coating device, in particular a varnishing unit variable in combination with at least one flexibly each variable print images printing, z. B. uses non-impact printing device designed as an inkjet printer, both the conventional printing device or the coating device and the non-impact printing device are used in an ongoing production inline, each at the optimal working speed for them. Such a hybrid machine arrangement is particularly useful for the production of packaging materials, e.g. B. of sheets for the production of folding boxes is very advantageous because the strengths of each of the printing devices are used, which leads to a flexible and economical production of the packaging. Thus, in particular, arch-shaped substrates of rigid design can be printed in a non-impact printing device, advantageously in a flat state and in a horizontal position. The length of a linear transport device can be adapted to a different number of printing units or printing stations (color separations) and (intermediate) dryer configurations z. B. for water-based or UV-curing printing inks or inks, than would be the case with a rotary transport device via cylinder. With a linear transport device, when using arcuate substrates of variable format lengths, a constant arc gap between arcuate substrates that are transported at a distance in direct succession can also be realized more easily. On the other hand, the transport of curved substrates by means of rotating bodies, in particular cylinders and gripper bars or gripper trolleys, each with a transfer of the curved substrates to a subsequent processing station, as is known from sheet-fed offset printing machines, ensures the highest possible register accuracy. Further advantages are evident from the explanations below.

Claims (8)

Machine arrangement with several processing stations (01; 02; 03; 04; 06; 07; 08; 09; 11; 12) each for processing arcuate substrates (51), with a device for the sequential transport of individual substrates (51) each with one along a movement path moved gripper carriage (23), wherein the respective gripper carriage (23) is guided along two longitudinally to its movement path parallel to each other and spaced apart chain tracks (77), the gripper carriage (23) in question in a transfer area arranged at a certain position of its movement path , in which the respective gripper carriage (23) takes over the respective substrate (51) to be transported from another transport device, and / or in a transfer area arranged at a certain position of its movement path, in which the respective gripper carriage (23) receives the respective transported substrate (51) each delivers to a further transport device, each ils is guided by a guide element (71) arranged between the spaced chain tracks (77) along the path of movement of the relevant gripper carriage (23), the guide element (71) in the relevant transfer area and / or in the relevant transfer area between the spaced chain tracks (77 ) is arranged in a stationary manner, the gripper carriage (23) guided along the spaced chain tracks (77) being fixed transversely to the movement path by means of the guide element (71), characterized in that the device for the sequential transport of individual substrates (51) in the transport direction ( T) of these substrates (51) is arranged in front of a processing station (06) designed as a non-impact printing device (06), the guide element (71) being designed as a rigid rail, with one on each gripper carriage (23) Roller pair is arranged, the guide element (71) through a gap between the respective Lauff surfaces of the two rollers (72; 73) of the relevant pair of rollers is performed. Machine arrangement according to Claim 1 , characterized in that the relevant substrate (51) to be transported is held on an edge extending longitudinally to the relevant gripper carriage (23) by at least one holding means (79) arranged on this gripper carriage (23). Machine arrangement according to Claim 1 or 2 , characterized in that the guide element (71) has a wedge-shaped run-on (74). Machine arrangement according to Claim 1 or 2 or 3 , characterized in that endlessly circulating conveyor chains are arranged along the chain tracks (77), the conveyor chains each being driven by at least one chain wheel (24; 81). Machine arrangement according to Claim 1 or 2 or 3 or 4th , characterized in that the chain wheel (24; 81) of one chain track (77) arranged either in the transfer area or in the transfer area and the chain wheel (24; 81) of the other chain track arranged in the same area (77) are connected to one another by a common shaft (76). Machine arrangement according to Claim 1 or 2 or 3 or 4th or 5 , characterized in that the device for the sequential transport of individual substrates (51) in the transport direction (T) of these substrates (51) is behind a processing station (02; 04) designed as a primer application device (02) or as an offset printing device (04) and is arranged in front of the processing station (06) designed as a non-impact printing device (06). Machine arrangement according to Claim 1 or 2 or 3 or 4th or 5 or 6th , characterized in that the non-impact printing device (06) is designed as at least one inkjet printing device. Machine arrangement according to Claim 1 or 2 or 3 or 4th or 5 or 6th or 7th , characterized in that the transport device assigned to the transfer area, to which the respective gripper carriage (23) delivers the respective transported substrate (51), is designed as a transport belt (17).
