Abstract

A method for operating a production and packaging installation for hygiene products, wherein the hygiene products are produced by a production machine, and the hygiene products produced are packaged by at least two packaging machines which are assigned to the production machine and are intended for packaging the hygiene products in particular so that they are ready for dispatch. At least two packaging machines assigned to a grouping conveyor form a machine group, wherein the performance of the packaging machines of the machine group are adapted automatically in accordance with the performance of the production machine and/or the individual performances available for the packaging machines of the machine group, and/or wherein the number of hygiene products with which the holders of the grouping conveyor are filled is selected automatically for each holder in dependence on which of the packaging machines the hygiene product of the respective holder is intended.

First claim

The invention claimed is:

1. A method for operating a production and packaging installation ( 10 ) for hygiene products ( 11 ) in which the hygiene products ( 11 ) are produced, the production and packaging installation ( 10 ) comprising a grouping conveyor ( 16 ) assigned to a machine group comprising a plurality of packaging machines (A-D), the method comprising:
producing the hygiene products ( 11 ) in a unit for producing the hygiene products ( 11 );
supplying individually the hygiene products ( 11 ) produced by the unit for producing the hygiene products ( 11 ), one after the other, to the grouping conveyor ( 16 ) which has individual holders for the hygiene products ( 11 );
filling a respective one of the individual holders with either (a) one of the hygiene products ( 11 ) or (b) a hygiene-product group comprising a plurality of the hygiene products ( 11 );
assigning at least one of the individual holders to one of the plurality of packaging machines (A-D);
removing the one of the hygiene products ( 11 ) or the hygiene-product group from the respective one of the individual holders in which it is located by pushing the one of the hygiene products ( 11 ) or the hygiene-product group from the respective one of the individual holders into one of the plurality of packaging machines (A-D), thereby supplying the one of the hygiene products ( 11 ) or the hygiene-product group to the one of the plurality of packaging machines (A-D); and then;
packaging (a) the one of the hygiene products ( 11 ) or the hygiene-product group from one of the individual holders together with (b) at least another of the one of the hygiene products ( 11 ) or another of the hygiene-product groups from another of the individual holders into a pack ( 21 - 24 ),
wherein, prior to the filling operation, each of the individual holders is automatically assigned in each case to one of the plurality of packaging machines (A-D) such that the one of the hygiene products ( 11 ) or the hygiene-product group located in the one of the individual holders assigned to the one of the plurality of packaging machines (A-D) is subsequently fed to the one of the plurality of packaging machines (A-D),
wherein the individual holders are filled with a number of the hygiene products ( 11 ) selected automatically for each of the individual holders in dependence on which of the one of the plurality of packaging machines (A-D) (a) the one of the hygiene products ( 11 ) or the hygiene-product group from the one of the individual holders together with (b) the at least another of the one of the hygiene products ( 11 ) or the another of the hygiene-product groups from the another of the individual holders is intended for,
wherein at least two of the plurality of packaging machines (A-D) are assigned to the unit for producing the hygiene products ( 11 ),
wherein at least one of the plurality of packaging machines (A-D) packages (a) the one of the hygiene products ( 11 ) or the hygiene-product group from one of the individual holders together with (b) the at least another of the one of the hygiene products ( 11 ) or the another of the hygiene-product groups from the another of the individual holders into the pack ( 21 - 24 ) which, in respect of the number of the hygiene products ( 11 ) contained therein, differ from the pack ( 21 - 24 ) of at least one other of the plurality of packaging machines (A-D) and
wherein, during the filling of the individual holders, the number of the hygiene products ( 11 ) provided in the pack ( 21 - 24 ) is automatically divided up between a plurality of the individual holders, in dependence on the number of the hygiene products ( 11 ) to be contained in the pack ( 21 - 24 ).

2. The method as claimed in claim 1 , further comprising, in the event of one of the plurality of packaging machines (A-D) failing, assigning each of the individual holders assigned to the failed one of the packaging machines (A-D) to another one of the plurality of packaging machines (A-D).

3. The method as claimed in claim 2 , further comprising feeding the hygiene products ( 11 ) or the hygiene-product groups currently assigned to the failed one of the packaging machines (A-D) to the another one of the plurality of packaging machines (A-D).

4. The method as claimed in claim 1 , further comprising automatically adapting the performances of the plurality of packaging machines (A-D) in accordance with at least one from a group consisting of the performance of the unit for producing the hygiene products ( 11 ) and in accordance with the individual performances of the plurality of packaging machines (A-D).

5. The method as claimed in claim 4 , further comprising, where the performance of one of the plurality of packaging machines (A-D) has been, or is being, reduced, the respective performance of one or any other of the plurality of packaging machines (A-D) is increased automatically in order to compensate for the performance reduction.

6. The method as claimed in claim 4 , further comprising, during normal operation of the plurality of packaging machines (A-D), the performance of the plurality of packaging machines (A-D) is adjusted automatically, in accordance with the performance of the unit for producing the hygiene products ( 11 ), to the smallest value where all of the hygiene products ( 11 ) produced by the unit for producing the hygiene products ( 11 ) are packaged by the plurality of packaging machines (A-D) assigned to the grouping conveyor ( 16 ).

7. The method as claimed in claim 4 , further comprising, where the maximum-adjustment performances of the plurality of packaging machines (A-D) assigned to the grouping conveyor ( 16 ) are insufficient for packaging all of the hygiene products ( 11 ) coming from the unit for producing the hygiene products ( 11 ) at the given level of performance of the unit for producing the hygiene products ( 11 ), the performance of the unit for producing the hygiene products ( 11 ) is reduced automatically to a value at which all the hygiene products ( 11 ) produced is packaged.

8. The method as claimed in claim 4 , further comprising sensing and communicating the current performances of each of the plurality of packaging machines (A-D) and the current performance of the unit for producing the hygiene products ( 11 ) to a central control device ( 27 ) of the installation ( 10 ), and, in dependence on the values sensed, the central control device ( 27 ) determines performance values for the plurality of individual packaging machines (A-D) and for the unit for producing the hygiene products ( 11 ).

9. The method as claimed in claim 8 , further comprising communicating the performance values in each case to local machine-control means ( 12 , 15 , 17 - 20 ) that are assigned in each case to each of the plurality of packaging machines (A-D) and the unit for producing the hygiene products ( 11 ).

10. The method as claimed in claim 1 , wherein the unit for producing the hygiene products ( 11 ) is a production machine (F).

11. A production and packaging installation for a hygiene product packaging operation, comprising:
a unit for producing hygiene products ( 11 );
a plurality of packaging machines (A-D) for packaging the hygiene products ( 11 );
a grouping conveyor ( 16 ) which has individual holders for the hygiene products ( 11 ), and to which the plurality of packaging machines (A-D) are assigned, and to which the hygiene products ( 11 ) produced by the unit for producing the hygiene products ( 11 ) is supplied individually, and one after the other, prior to the packaging operation;
a control device ( 27 ) for automatically selecting a number of the hygiene products ( 11 ) with which the individual holders of the groupi
