Abstract

An apparatus for printing different colors on packages includes holding-and-centering units, each having a primary and a secondary part. The primary part is held at a holding position during package handling. The secondary part is mounted in the primary part to be rotatable about a vertical axis of the unit. The secondary part receives a functional element necessary for handling a package. A plurality of secondary parts adapted to different types, forms and/or sizes of packages are associated with the primary parts.

First claim

The invention claimed is:

1. An apparatus for treating packages by applying furnishing features to said packages, said apparatus comprising a plurality of holding-and-centering units, each of which comprises a primary part and a secondary part, wherein at least one of said primary part and said secondary part comprises a coding, wherein said primary part is held at a holding position during package handling, wherein said secondary part is mounted on or in said primary part so as to be rotatable about a vertical axis of said holding-and-centering unit, wherein said secondary part receives a functional element necessary for handling a package, wherein said secondary part is driven by a motor during handling of a package, wherein a plurality of secondary parts adapted to different types, forms and/or sizes of packages are associated with said primary parts, wherein package handling comprises at least one of holding, centering, aligning, moving, rotating, and pivoting a package at said holding positions, wherein said features comprise printed material having plural colors, wherein said apparatus further comprises a package inlet, a package outlet, a package-transport path on which packages are moved in a transport direction from said package inlet to said package outlet, and a sensor, wherein said coding indicates rotational angle position to said sensor, wherein said package-transport path comprises at least one transport-and-treatment element that can be driven to rotate about a vertical machine-axis, wherein said transport-and-treatment element comprises a plurality of holding positions, each of which comprises one of said holding-and-centering units for package handling.

2. The apparatus of claim 1 , further comprising an electromagnetic direct drive for controlled handling of a package, wherein said electromagnetic direct drive comprises a rotor and a stationary structure, wherein said stationary structure is one of a stator and a solenoid array, wherein said rotor comprises an array of permanent magnets that interact with said stationary structure, and wherein controlled handling is selected from the group consisting of aligning a package and rotating a package.

3. The apparatus of claim 1 , wherein said secondary part comprises a format-adapted interchangeable mounting-and-base part and an infinitely controllable electric motor, and wherein said primary part comprises a motor housing of said infinitely controllable motor.

4. The apparatus of claim 1 , further comprising functional elements for aligning and/or controlled moving of a package during handling thereof, wherein said functional elements are provided on a respective secondary part.

5. The apparatus of claim 1 , wherein said package-transport path comprises a plurality of transport-and-treatment elements adjacent to one another for transporting packages, wherein each of said transport-and-treatment elements can be driven to rotate said holding positions about said vertical machine-axis.

6. The apparatus of claim 1 , wherein said secondary parts are each configured with a format-adapted interchangeable mounting-and-base part.

7. The apparatus of claim 1 , wherein said holding-and-centering units comprise pucks, wherein at said package inlet, each puck picks up a package, and wherein each puck is moved with said picked-up package from said package inlet to said package outlet along said package-transport path, wherein upon arriving at said package outlet, each puck releases said picked-up package, and wherein said apparatus further comprises a puck-transport path over which pucks are returned from said package outlet back to said package inlet.

8. The apparatus of claim 7 , wherein said puck-transport path is at least in part constituted by those transport-and-treatment elements that are also part of said package-transport path.

9. The apparatus of claim 7 , further comprising receptacles formed between said holding positions to receive said pucks, wherein said receptacles are part of said puck-transport path.

10. The apparatus of claim 1 , further comprising, at each holding position, a holder configured as a carrier for holding a holding-and-centering element, wherein said holder is height-adjustable in a direction along said machine axis.

11. The apparatus of claim 1 , further comprising, at each holding position, a mechanism for controlled holding and releasing of holding-and-centering elements.

12. The apparatus of claim 1 , wherein said secondary part comprises an RFID tag.

13. The apparatus of claim 1 , wherein each holding position comprises an inkjet print head and a radiation source for at least one of curing and drying of ink, wherein said radiation source is selected from the group consisting of a thermal-radiation source, a microwave-radiation source, and a UV-radiation source.

14. The apparatus of claim 13 , wherein said print head is adjustable in at least one of a direction along said machine axis and an inclination relative to said machine axis.

15. The apparatus of claim 1 , wherein at least one transport-and-treatment element is connectable to a pressure medium, wherein said transport-and-treatment element comprises at least one coupling element, wherein each of said holding-and-centering units further comprises a quick-acting coupling for coupling to a source of pressure medium via said coupling element, and wherein said pressure medium is selected from the group consisting of a gaseous medium, a vaporous medium, and compressed air, whereby a package held at a holding-and-centering unit at said transport-and-treatment element is able to be pressurized with said pressure medium.

16. The apparatus of claim 15 , wherein said quick-acting coupling is configured as a non-return valve such that after preloading a package with said pressure medium to a pressure, said pressure can be maintained in said package as said package traverses said package element transport section.

17. The apparatus of claim 1 , wherein each secondary part includes a centering-and-holding element that is configured for passively holding a package with a spring force.

18. The apparatus of claim 1 , wherein each holding-and-centering unit comprises a recess configured to cover said package in a region of a mouth thereof.

19. The apparatus of claim 1 , wherein said holding-and-centering units are held at an associated printing segment by passive application of a holding force to primary parts thereof, and wherein said holding-and-centering units are actively removed from said printing segments.

20. The apparatus of claim 1 , further comprising an electromagnetic direct drive for controlled handling of a package, wherein said electromagnetic direct drive comprises a rotor and a stationary structure, wherein said stationary structure is one of a stator and a solenoid array, and wherein said rotor comprises an array of permanent magnets that interact with said stationary structure.

21. The apparatus of claim 1 , wherein each of said holding-and-centering units comprises a secondary part that comprises a format-adapted interchangeable mounting-and-base part and an infinitely controllable electric motor, and wherein said primary part comprises a motor housing of said infinitely controllable motor.

22. An apparatus for treating packages by applying furnishing features to said packages, said apparatus comprising a plurality of holding-and-centering units, each of which comprises a primary part and a secondary part, wherein at least one of said primary part and said
