Abstract

An apparatus for at least partially folding outer packaging includes a conveyor that transports the outer packaging, a first folder, a second folder, and a set of one or more rotating folders that are part of the second folder. The first folders swivel on the conveyor and fold a front side segment of the outer package that adjoins its base segment and connecting segments that are hinged relative to the base segment. The second folders are above the conveyor device and are configured to fold connecting segments that are hinged relative to the base segment of the outer package. The second folders act on the front side segment of the outer package in a direction oriented against an effective direction of the first folding device around a fold line running in the particular connecting segments.

First claim

The invention claimed is:

1. An apparatus for at least partially folding outer packaging, wherein said outer packaging has multiple segments connected by fold lines, and wherein said outer packaging has a base segment, said apparatus comprising a conveyor device, a first folding devices, a second folding devices, and a set comprising at least one rotating folder, wherein said conveyor device transports said outer packaging in a direction-of-transport, wherein said conveyor device transports said outer packaging in a position in which at least said base segment of said outer packaging rests on said conveyor device, wherein said first folding devices are arranged on said conveyor device such that said first folding devices swivel, wherein said first folding devices are configured to swivel in a first direction for folding of a front side segment of said outer package that adjoins said base segment of said outer package and connecting segments that are hinged relative to said base segment of said outer package, wherein said second folding devices are provided above said conveyor device, wherein said second folding devices are configured to effect a folding of said connecting segments that are hinged relative to said base segment of said outer package, wherein said second folding devices are configured to act on said front side segment of said outer package in a second direction that is oriented opposite said first direction to fold along a fold line running in said particular connecting segments, wherein said at least one rotating folder is driven to rotate about an axis of rotation, and wherein said second folding devices comprise said at least one rotating folder, wherein said first folding devices and said second folding devices engage opposite sides of said outer packaging.

2. The apparatus of claim 1 , further comprising a servo-motor, wherein said servo-motor drives said at least one rotating folder.

3. The apparatus of claim 2 , wherein said servo-motor is configured to be triggered with a speed profile that depends on a format of said outer packaging.

4. The apparatus of claim 2 , further comprising a control system interacting with said servo-motor, wherein said control system is programmed and configured trigger said servo-motor with an angular acceleration profile that depends on a format of said outer packaging.

5. The apparatus of claim 2 , further comprising a control system interacting with said servo-motor, wherein said control system is programmed and configured to trigger said servo-motor with a rotary motion profile that depends on a format of said outer packaging.

6. The apparatus of claim 5 , wherein said control system is further configured to change a direction of rotation of said at least one rotating folder.

7. The apparatus of claim 2 , wherein said servo-motor is configured to be triggered based on a stored parameter set, said parameter set comprising different format-dependent parameters for triggering said servo-motor.

8. The apparatus of claim 1 , further comprising a shaft, wherein said at least one rotating folder is arranged on said shaft, wherein said at least one rotating folder comprises two rotating-folder segments extending radially opposite each other.

9. The apparatus of claim 8 , wherein said rotating-folder segments comprise flat material.

10. The apparatus of claim 1 , wherein said set comprises at least two rotating folders.

11. The apparatus of claim 10 , further comprising a shaft, wherein said rotating folders are arranged on said shaft so that they can be moved axially.

12. The apparatus of claim 10 , wherein a distance of said rotating folders relative to said conveyor device is adjustable.

13. A method for at least partially folding outer packaging that has multiple segments connected by fold lines, said method comprising resting a base segment of said outer packaging on a conveyor device; using said conveyor device, moving said outer packaging in a direction-of-transport; swiveling first folding devices, which are arranged to swivel on said conveyor device, in a first direction, thereby folding a front side segment adjoining said base segment and connecting segments hinged on said front side segment relative to said base segment; and using second folding devices that are provided above said conveyor device and that have rotating folders that are driven to rotate about an axis of rotation, folding said connecting segments about a fold line running in said particular connecting segments by acting on said front side segment in a second direction that is oriented against said first direction, wherein said first folding devices and said second folding devices engage opposite sides of said outer packaging.

14. The method of claim 13 , further comprising, using a servo-motor, driving said rotating folders.

15. The method of claim 14 , further comprising selecting a speed profile that depends on said outer packaging, and driving said rotating folders with said speed profile.

16. The method of claim 14 , further comprising selecting an angular acceleration profile that depends on said outer packaging, and driving said rotating fodders with said angular acceleration profile.

17. The method of claim 14 , further comprising selecting a rotary motion profile that depends on said outer packaging, and driving said rotating fodders with said rotary motion profile.

18. The method of claim 13 , further comprising driving said rotating folders in an alternating direction of rotation.

19. The method of claim 13 , further comprising moving said rotating folders at least partially in spaces forming between containers arranged in rows in an area of said base segment of said outer packaging.
