Abstract

The invention provides a device for sorting out containers which were applied an incorrect print by a direct printing machine. The device comprises a transport device for transporting pucks, which are adapted to transport containers, along a transport path away from the direct printing machine, where the transport path comprises at least a primary transport path and a secondary transport path, an inspection device for inspecting the print on the containers, a decoupling device, in particular comprising a pusher system or a slider system, for decoupling pucks from the primary transport path to the secondary transport path, and a control device adapted to control the decoupling device such that pucks with containers, for which the inspection device has detected an incorrect print, are decoupled to the secondary transport path.

First claim

1 . Device for sorting out containers which were applied an incorrect print by a direct printing machine, comprising
a transport device for transporting pucks, which are adapted to transport containers, along a transport path away from the direct printing machine, where the transport path comprises at least a primary transport path and a secondary transport path, an inspection device for inspecting the print on the containers, a decoupling device for decoupling pucks from the primary transport path to the secondary transport path, and a control device adapted to control the decoupling device such that pucks with containers for which the inspection device has detected an incorrect print are decoupled to the secondary transport path.

2 . Device according to claim 1 , where the decoupling device is arranged in a decoupling section, where a guide and/or at least one puck lock are further arranged in the decoupling section.

3 . Device according to claim 2 , where the secondary transport path and or the primary transport path are adapted to transport pucks to a removal section.

4 . Device according to claim 3 , where the primary transport path is adapted to transport pucks to the removal section and where the device comprises a first deflection device, which is configured such that whether pucks are transported from the primary transport path or from the secondary transport path into the removal section is adjustable by means of the first deflection device.

5 . Device according to claim 4 , where the control device is adapted to control the first deflection device such that only pucks from the primary transport path or only pucks from the secondary transport path enter the removal section in a predetermined period of time.

6 . Device according to claim 1 , where the secondary transport path is adapted to transport the pucks to a merging device, where the merging device is adapted to merge pucks into the primary transport path in the direction of transport upstream of the inlet of the direct printing machine.

7 . Device according to claim 6 , wherein the device comprises a second deflection device which is adapted such that it is adjustable whether pucks are transported from the removal section to the merging device or to another system region.

8 . Device according to one of the claim 4 , where the first and/or the second deflection device can each comprise at least a switch and/or at least a guide and/or at least a puck lock.

9 . Device according to claim 1 , where the decoupling device comprises a pusher system, where the pusher system is adapted to push the pucks from a conveyor belt of the primary transport path onto a conveyor belt of the secondary transport path.

10 . Method for sorting out containers which were applied an incorrect print by a direct printing machine, comprising
transporting pucks, which are adapted to transport containers and in which containers which were applied a print are standing, along a transport path away from the direct printing machine, where the transport path comprises at least a primary transport path and a secondary transport path, inspecting the print on the containers, and decoupling pucks with containers, for which it was detected that they were applied an incorrect print, from the primary transport path to the secondary transport path.

11 . Method according to claim 10 , comprising providing a supply of pucks from the secondary transport path and optionally from the primary transport path to a removal section and removing containers from the pucks manually and/or by machine in the removal section.

12 . Method according to claim 11 , where only pucks from the primary transport path or from the secondary transport path are supplied to the removal section in a predetermined period of time.

13 . Method according to claim 12 , where with containers which were applied a correct print are supplied to the removal section and pucks with containers which were applied an incorrect print are stored in the secondary transport path until there is no more room for pucks in the secondary transport path, and subsequently the stored pucks, but no pucks from the primary transport path, are transported to the removal section.

14 . Method according to claim 13 , where empty pucks from the removal section are merged in a merging section into the primary transport path in the direction of transport upstream of the direct printing machine.

15 . (canceled)
