Abstract

The invention relates to a product stacking device for forming product stacks ( 12 a - k ) of product groups ( 14 a - k ) consisting of products ( 16 a - k ), which lie flatly and/or are brought into a shingled product arrangement ( 64 a - k ), during a transportation movement ( 28 a - k ). The product stacking device includes at least two stack contact surfaces ( 20 a - k ), which are provided in order to form the product stack ( 12 a - k ) by reducing a spacing ( 24 a - k ) between the stack contact surfaces ( 20 a - k ), the stack contact surfaces lying opposite one another in a product group direction ( 26 a - k ).

First claim

What is claimed is:

1. A product stacking device for forming product stacks ( 12 a - k ) of product groups ( 14 a - k ) consisting of products ( 16 a - k ), each of which includes a primary face defined as the largest face of the product, the device comprising at least two stop means ( 18 a - k ) mounted on a common conveyor with stack contact surfaces ( 20 a - k ), which are configured to form a product stack ( 12 a - k ) on a product support surface of the common conveyor by a reduction of a spacing ( 24 a - k ) between the stack contact surfaces ( 20 a - k ), the stack contact surfaces lying opposite one another in a product group direction ( 26 a - k ), wherein at least one of the stop means is provided for spacing the product groups of the delivered products apart from one another, and wherein the device is 1) operable to form a product stack configured such that the primary faces of the products are oriented at 0 degrees relative to the product support surface and 2) operable to form a product stack configured such that the primary faces of the products are oriented at 90 degrees relative to the product support surface.

2. The product stacking device according to claim 1 , wherein at least one of the at least two stop means ( 18 a - k ) is formed by at least one of a driver ( 30 a - k ) and a counter holder ( 32 a - e; g - k ).

3. The product stacking device according to claim 1 , further including at least one bearing unit ( 36 a - c; f - j ) by means of which at least one of the at least two stop means ( 18 a - c; f - k ) is rotatably mounted about at least one degree of freedom ( 38 a - c; f - k ).

4. The product stacking device according to claim 3 , further including at least one drive unit ( 46 a - h ) configured to drive the at least one of the at least two stop means ( 18 a - h ) in the at least one degree of freedom ( 38 a - c; f - h and 44 a - h ).

5. The product stacking device according to claim 1 , further including at least one bearing unit ( 40 a - h ) by means of which at least one of the at least two stop means ( 18 a - h ) is mounted in a translationally movable manner at least along a working section ( 42 a - h ) in at least one degree of freedom ( 44 a - h ).

6. The product stacking device according to claim 5 , further including at least one drive unit ( 46 a - h ) configured to drive the at least one stop means ( 18 a - h ) in the at least one degree of freedom ( 38 a - c; f - h and 44 a - h ).

7. The product stacking device according to claim 1 , wherein at least one of the at least two stop means ( 18 e - f; h ) has stack contact surfaces ( 20 e - f; h ) on two sides ( 48 e - f; h and 50 e - f; h ) lying opposite one another in the product group direction ( 26 e - f; h ).

8. The product stacking device according to claim 1 , further including at least one linkage configured to move the stop means.

9. The product stacking device according to claim 1 , further including at least one electrical and/or electronic control unit ( 54 b; d - h ) configured to control position and speed of the at least two stop means.

10. The product stacking device according to claim 1 , wherein at least one of the at least two stop means is formed by a lateral guide placed at an angle in relation to the transportation movement.

11. The product stacking device according to claim 1 , wherein an input belt ( 62 k ) is configured to push the product groups ( 14 k ) resting on the input belt ( 62 k ) with the transportation movement ( 28 k ) against stop means ( 18 k ) that are moving slower in relation to said transportation movement ( 28 k ).

12. A method for forming at least one horizontal or vertical product stack ( 12 a - k ) with a product stacking device ( 10 a - k ) according to claim 1 , the method comprising forming the at least one product stack ( 12 a - k ) by reducing the spacing ( 24 a - k ) between the stack contact surfaces ( 20 a - k ) of the at least two stop means ( 18 a - k ), said stack contact surfaces lying opposite one another in the product group direction ( 26 a - k ).

13. A delivery device for delivering products ( 16 a - k ) to a packaging process, comprising a product stacking device ( 10 a - k ) according to claim 1 .

14. A product stacking device for forming product stacks of product groups consisting of products, which lie flatly and/or are brought into a shingled product arrangement, during a transportation movement, comprising at least two stop means with stack contact surfaces, which are configured to form a product stack by a reduction of a spacing between the stack contact surfaces, the stack contact surfaces lying opposite one another in a product group direction, wherein at least one of the at least two stop means is formed by a lateral guide placed at an angle in relation to the transportation movement.
