Abstract

A method and to a device for handling hygiene products, in particular nappies, wherein the products are transported by a feed conveyor in a first transport direction into compartments of a removal conveyor, in particular a grouping conveyor, which transports the products in a second transport direction, wherein the second transport direction extends transversely, in particular perpendicularly, to the first transport direction. At least one intermediate conveyor which serves to reduce the transport speed of the products in the first transport direction is located between the feed conveyor and the removal conveyor.

First claim

What is claimed is:

1. A method for handling hygiene products ( 10 ), in particular diapers, the products ( 10 ) being transported by way of a feed conveyor ( 12 ) in a first transport direction ( 18 ) into compartments ( 17 ) of a discharge conveyor ( 11 ), in particular of a grouping conveyor, which transports the products ( 10 ) in a second transport direction ( 19 ), the second transport direction ( 19 ) running transversely, in particular perpendicularly, with respect to the first transport direction ( 18 ), wherein at least one intermediate conveyor ( 13 ) which serves to decrease the transfer speed of the products ( 10 ) in the first transport direction ( 18 ) is arranged between the feed conveyor ( 12 ) and the discharge conveyor ( 11 ), wherein the intermediate conveyor ( 13 ) and the discharge conveyor ( 11 ) are configured as compartment conveyors, wherein regions of the products ( 10 ) which protrude out of the compartments ( 17 ) are stabilized by way of at least one further compartment conveyor ( 14 , 15 ), in particular by way of contact of the products ( 10 ) with dividing walls ( 16 ) of the further compartment conveyor ( 14 , 15 ), wherein each further compartment conveyor ( 14 , 15 ) being driven continuously in the second transport direction ( 19 ).

2. The method as claimed in claim 1 , wherein the intermediate conveyor ( 13 ) runs at least substantially parallel to the second transport direction ( 19 ).

3. The method as claimed in claim 1 , wherein the transport speed of the products ( 10 ) in the first transport direction ( 18 ) is decreased by way of temporary contact of the products ( 10 ) with the intermediate conveyor ( 13 ) or members thereof.

4. The method as claimed in claim 1 , wherein the transport speed of the products ( 10 ) in the first transport direction ( 18 ) is decreased by way of friction between the products ( 10 ) and the intermediate conveyor ( 13 ) or members thereof.

5. The method as claimed in claim 1 , wherein the intermediate conveyor ( 13 ) and the discharge conveyor ( 11 ) are driven continuously and at the same speed in the second transport direction ( 19 ), and in that the two conveyors are configured as compartment conveyors and have dividing walls ( 16 ) for dividing compartments ( 17 ) of the respective conveyor, the two conveyors being driven in a manner which is oriented with respect to one another in such a way that the respective compartments ( 17 ) and dividing walls ( 16 ) are arranged so as to be aligned at least partially, with the result that the products ( 10 ) are transported one after another by way of the feed conveyor ( 12 ) through a compartment ( 17 ) of the intermediate conveyor ( 13 ) into a compartment ( 17 ) of the discharge conveyor ( 11 ), the products ( 10 ) being braked with regard to their transport speed in the first transport direction ( 18 ) by way of partial contact or friction with the dividing walls ( 16 ) of the intermediate conveyor ( 13 ) and of the discharge conveyor ( 11 ).

6. The method as claimed in claim 1 , wherein each further compartment conveyor ( 14 , 15 ) are arranged above at least one of the intermediate conveyor ( 13 ) and the discharge conveyor ( 11 ).

7. The method as claimed in claim 1 , wherein the compartment conveyor or the further compartment conveyors ( 14 , 15 ) run obliquely with respect to the transport plane of at least one of the intermediate conveyor ( 13 ) and the discharge conveyor ( 11 ), with the result that the dividing walls ( 16 ) of the compartment conveyor or the further compartment conveyors ( 14 , 15 ) are withdrawn gradually from the products ( 10 ) during the transport of the products ( 10 ) in the second transport direction ( 19 ).

8. The method as claimed in claim 1 , further comprising a diverter ( 22 ) arranged between the intermediate conveyor ( 13 ) and the discharge conveyor ( 11 ).

9. An apparatus for handling hygiene products ( 10 ), in particular diapers, with the feed conveyor ( 12 ) for transporting the products ( 10 ) in a first transport direction ( 18 ) into compartments ( 17 ) of a discharge conveyor ( 11 ), in particular of a grouping conveyor, the discharge conveyor ( 11 ) being configured to transport the products ( 10 ) in a second transport direction ( 19 ), and the second transport direction ( 19 ) running transversely, in particular perpendicularly, with respect to the first transport direction ( 18 ), comprising at least one intermediate conveyor ( 13 ) arranged between the feed conveyor ( 12 ) and the discharge conveyor ( 11 ), for decreasing the transport speed of the products ( 10 ) in the first transport direction ( 18 ), wherein the intermediate conveyor ( 13 ) and the discharge conveyor ( 11 ) are configured as compartment conveyors, and wherein regions of the products ( 10 ) which protrude out of the compartments ( 17 ) are stabilized by way of at least one further compartment conveyor ( 14 , 15 ), in particular by way of contact of the products ( 10 ) with dividing walls ( 16 ) of the further compartment conveyor ( 14 , 15 ), wherein each further compartment conveyor ( 14 , 15 ) being driven continuously in the second transport direction ( 19 ).

10. The apparatus as claimed in claim 9 , wherein the apparatus is configured to drive the intermediate conveyor ( 13 ) and the discharge conveyor ( 11 ) continuously and at the same speed in the second transport direction ( 19 ), and in that the two conveyors are configured as compartment conveyors and have dividing walls ( 16 ) for dividing compartments ( 17 ) of the respective conveyor, the apparatus being configured to drive the two conveyors in a manner which is aligned with respect to one another in such a way that the respective compartments ( 17 ) and dividing walls ( 16 ) are arranged so as to be aligned at least partially, with the result that products ( 10 ) are transported one after another by way of the feed conveyor ( 12 ) through a compartment ( 17 ) of the intermediate conveyor ( 13 ) into a compartment ( 17 ) of the discharge conveyor ( 11 ), the products ( 10 ) being braked with regard to their transport speed in the first transport direction ( 18 ) by way of partial contact with the dividing walls ( 16 ) of the intermediate conveyor ( 13 ) and the discharge conveyor ( 11 ).

11. The apparatus as claimed in claim 9 , wherein the compartments ( 17 ) are dimensioned in such a way that they are only slightly wider than the respective product ( 10 ), with the result that the product ( 10 ) is supported transversely with respect to the first transport direction ( 18 ) by way of the compartment ( 17 ) or its dividing walls ( 16 ).

12. The apparatus as claimed in claim 10 , wherein each further compartment conveyor ( 14 , 15 ) are arranged above at least one of the intermediate conveyor ( 13 ) and the discharge conveyor ( 11 ).

13. The apparatus as claimed in claim 9 , wherein the compartment conveyor or the further compartment conveyors ( 14 , 15 ) run obliquely with respect to the transport plane of at least one of the intermediate conveyor ( 13 ) and the discharge conveyor ( 11 ), with the result that the dividing walls ( 16 ) of the compartment conveyor or the further compartment conveyors ( 14 , 15 ) are withdrawn gradually from the products ( 10 ) during the transport of the products ( 10 ) in the second transport direction ( 19 ).

14. The apparatus as claimed in claim 9 , further comprising a diverter ( 24 ) arranged between the intermediate conveyor ( 13 ) and the discharge conveyor ( 11 ).

15. The apparatus as claimed in claim 9 , wherein the intermediate conveyor ( 13 ) is configured in the second transport directio
