Abstract

A device and a method for transporting flat products comprising at least one feeder and a first transport unit having at least two transport elements that can be set against side edges lying opposite one another of the flat products. The flat products can be gripped by the transport elements and can be transported upright in the transport direction. In the transporting process, the flat products are received in the first transport unit, are transported within the latter, and are held upright at the side edges by the transport elements.

Claims

1. A device for transporting flat products extending in a plane, comprising:

a first transport unit transporting said flat products in a transport direction, and

at least one feeder feeding said flat products to said first transport unit,

said first transport unit comprising at least two first transport elements,

said first transport elements being arranged parallel to said transport direction,

said flat products comprising side edges lying opposite to one another,

wherein said first transport elements can be set against said opposite side edges thereby gripping and separately holding said flat products and transporting said flat products with their plane being upright with respect to said transport direction.

2. The device of claim 1, further comprising:

at least one second transport unit, comprising at least one second transport element, said at least one second transport element transporting said flat products further in said transport direction and being arranged parallel to said transport direction, and said at least one second transport element being capable of removing said flat products from said device,

wherein said at least one second transport element can be set against at least one edge of said side edges of said flat products thereby gripping and separately holding said flat products and transporting said flat products with their plane being upright with respect to said transport direction.

3. The device of claim 2, wherein said second transport unit comprises:

two second transport elements,

said two second transport elements being arranged in a distance from one another, said distance can be varied perpendicularly with respect to said transport direction.

4. The device of claim 1, wherein at least each of said first transport elements of said first transport unit comprises:

at least one transport belt,

wherein said side edges of said flat products can be set onto said transport belts and

said side edges of said flat products can be gripped by said transport belts.

5. The device of claim 1, wherein said transport units comprise:

at least one further transport element that can be set against at least one further edge of said flat products.

6. The device of claim 5, wherein said at least one further edge is the lower edge of said flat products.

7. The device of claim 5, wherein each of said transport units comprises:

at least one further transport element.

8. The device of claim 7, wherein said at least one further edge is the lower edge of said flat products.

9. The device of claim 1, further comprising:

a pusher,

said pusher being capable of moving at least perpendicularly with respect to said transport direction and that it can be moved against an upper edge of said flat products.

10. The device of claim 9, wherein said pusher is capable of moving additionally in said transport direction.

11. The device of claim 1, further comprising:

a control unit,

said control unit controls at least said transport units.

12. The device of claim 1, further comprising:

a control unit,

said control unit controls at least said transport units and is designed to receive data from said feeder and to divide said flat products into separate groups of flat products in said device on the basis of said data, and

wherein said groups are separated from one another by spacings along said transport direction.

13. The device of claim 1, further comprising:

a control unit controlling at least said transport units, and

a second unit being positioned in front of said feeder,

said control unit being designed to receive data from said second unit and to divide said flat products into separate groups of flat products in said device on the basis of said data,

wherein said groups are separated from one another by spacings along said transport direction.

14. The device of claim 1, further comprising:

a control unit controlling at least said transport units, and

a second unit being connected to said feeder,

said control unit being designed to receive data from said second unit and to divide said flat products into separate groups of flat products in said device on the basis of said data,

wherein said groups are separated from one another by spacings along said transport direction.

15. A method for transporting flat products extending in a plane in a transport direction,

said flat products comprising side edges lying opposite one another,

said method comprising the following steps:

receiving of said flat products from a feeder into at least one first transport unit, said first transport unit having at least two first transport elements, and

transporting of said flat products within said first transport unit in said transport direction, wherein said flat products are separately held and gripped by said first transport elements at said side edges and are transported with their plane being upright with respect to said transport direction.

16. The method of claim 15, wherein said flat products are envelopes.

17. The method of claim 15, wherein said flat products are fed individually and said flat products being transported in said first transport unit are arranged parallel to one another and behind one another, and

wherein said flat products can be arranged at any desired spacing from one another with respect to said transport direction.

18. The method of claim 15, wherein said flat products are fed in small packets, and said flat products being transported in said first transport unit are arranged parallel to one another and behind one another, and

wherein said flat products can be arranged at any desired spacing from one another, seen in the direction of said transport direction.

19. The method of claim 15, further comprising the step of:

dividing said flat products from said feeder into separate groups of flat products within said first transport unit, by introducing spacings along said transport direction.

20. The method of claim 19, wherein said step of introducing said spacings comprises a brief increase in the transport speed of said first transport elements between the receiving of two of said flat products from said feeder.

21. The method of claim 15, further comprising the steps of:

continuous transferring said flat products from said first transport unit into at least one second transport unit having at least one second transport element,

further transporting said flat products within said second transport unit in said transport direction, wherein said flat products are separately held by said second transport element at least at one edge and are transported with their plane being upright with respect to said transport direction.

22. The method of claim 15, further comprising the step of:

removing said flat products from said second transport unit and transferring said flat products into a transport container.
