Abstract

The invention relates to a transport roller ( 1 ) for a conveying device ( 100 ), in particular for conveying pallets and/or containers, the transport roller ( 1 ) comprising: an in particular tube-shaped roller body ( 2 ), a drive wheel ( 5 ) for in particular connecting the transport roller ( 1 ) to a rotary drive ( 102 ) of a conveying device ( 100 ), in particular an adapter assembly (A) for connecting the drive wheel ( 5 ) to the roller body ( 2 ).

First claim

The invention claimed is:

1. A method for producing a conveyor roller,
the conveyor roller ( 1 ) comprising:
a cylindrical roller body ( 2 ),
a drive wheel ( 5 ), in particular for connecting the conveyor roller ( 1 ) to a rotary drive ( 102 ) of a conveyor device ( 100 ),
an adapter assembly (A) for connecting the drive wheel ( 5 ) to the roller body ( 2 ), the method comprising the following steps:
providing the, in particular tubular, roller body ( 2 ),
providing the drive wheel ( 5 ),
at least indirectly connecting the drive wheel ( 5 ) to the roller body ( 2 ) by applying a laser welded joint,
the roller body ( 2 ), the adapter assembly (A), and the drive wheel ( 5 ) are provided with a zinc layer ( 2 ) on the surface,
wherein the drive wheel ( 5 ), the adapter assembly (A) and the roller body ( 2 ) are provided with the zinc layer before assembly.

2. The method for producing the conveyor roller according to claim 1 ,
characterized by
a laser welded joint (S 1 , S 2 , S 3 , S 4 ) adapted for at least indirect connection of the drive wheel ( 5 ) to the roller body ( 2 ),
in particular wherein it is connected to each other by the laser welded joint (S 1 , S 2 , S 3 , S 4 )
the drive wheel ( 5 ) with the adapter assembly (A), in particular with the adapter tube ( 4 ) and/or
the roller body ( 2 ) with the adapter assembly (A), in particular with the adapter ring ( 3 ) and/or
the adapter ring ( 3 ) with the adapter tube ( 4 ), and/or
the drive wheel ( 5 ) directly with the roller body ( 2 ).

3. The method for producing the conveyor roller according to claim 2 ,
wherein the laser welded joint is arranged at
an end face or outer surface of the roller body ( 2 ) and/or
an end face of the drive wheel ( 5 ) and/or
at an end face and/or outer circumferential surface of the adapter tube ( 4 )

and/or
at an end face and/or outer circumferential surface of the adapter ring ( 3 ).

4. The method for producing the conveyor roller according to claim 1 ,
characterized
in that the corrosion protection (Z) is interrupted in the area of the laser welded joint (S 1 , S 2 , S 3 ).

5. A conveyor device ( 100 ), comprising
a plurality of conveyor rollers ( 1 ) produced according to claim 1 .

6. The conveyor device ( 100 ) according to claim 5 ,
wherein the conveyor device is adapted to convey a conveyed object,
wherein the conveyed object ( 101 ) has a weight of at least 100 kg, preferably at least 500 kg, and/or
wherein the conveyed object ( 101 ) comprises a container and/or a pallet.

7. The conveyor device ( 100 ) according to claim 5 ,
wherein the conveyor device ( 100 ) comprises
a rotary drive ( 102 ), comprising a motor ( 103 ) and a transmission means ( 104 ), for driving at least one of the conveyor rollers ( 1 ), wherein the transmission means ( 104 ) is drivingly connected to the drive wheel ( 5 ).

8. The method of producing the conveyor roller according to claim 1 ,
comprising the following further steps:
selecting a drive wheel ( 5 ), in particular from a plurality of differently formed drive wheels ( 5 );
selecting a roller body ( 2 ), in particular from a plurality of differently formed roller bodies ( 2 );
connecting the drive wheel ( 5 ) to the roller body ( 2 ) by means of the adapter assembly (A).

9. The method of producing the conveyor roller according to claim 1 ,
comprising the further steps of
defining an axial distance (X) between the drive wheel ( 5 ) and the roller body ( 2 ), and then
arranging the drive wheel ( 5 ) on the adapter assembly (A) and/or
arranging the adapter assembly (A) on the roller body ( 2 ), and/or
arranging the adapter ring ( 3 ) on the adapter tube ( 4 )

each in a position that depends on the defined axial distance.

10. A modular system for use in a method according to claim 1 , comprising,
a plurality of differently configured roller bodies ( 2 ),
a plurality of differently configured drive wheels ( 5 ),
adapter assemblies (A) for selectively connecting a selected one of the plurality of differently configured drive wheels ( 5 ) to a selected one of the plurality of differently configured roller bodies ( 2 ).

11. The modular system according to claim 10 ,
characterized in
that the roller bodies ( 2 ) have different inner diameters (d 22 ) and the adapter rings ( 3 ) of the adapter assemblies have different outer diameters (d 31 ) corresponding to the inner diameters (d 22 ) of the roller bodies ( 2 ).

12. The modular system according to claim 10 ,
characterized in
that the drive wheels ( 5 ) have different outer diameters (d 51 ) and identical inner diameters (d 52 ) and the adapter tubes ( 4 ) of the adapter assemblies have identical outer diameters ( 41 ) corresponding to the inner diameter (d 52 ) of the drive wheels ( 5 ),
and in particular in that the different adapter rings ( 3 ) have identical inner diameters (d 31 ) corresponding to the outer diameter (d 41 ) of the adapter tube ( 4 ).

13. The method for producing a conveyor roller according to claim 1 ,
characterized in
that the adapter assembly (A) comprises an adapter tube ( 4 ) and a separate adapter ring ( 3 ).

14. A method for producing a conveyor roller,
the conveyor roller ( 1 ) comprising:
a cylindrical roller body ( 2 ),
a drive wheel ( 5 ), in particular for connecting the conveyor roller ( 1 ) to a rotary drive ( 102 ) of a conveyor device ( 100 ),
an adapter assembly (A) for connecting the drive wheel ( 5 ) to the roller body ( 2 ), the method comprising the following steps:
providing the, in particular tubular, roller body ( 2 ),
providing the drive wheel ( 5 ),
at least indirectly connecting the drive wheel ( 5 ) to the roller body ( 2 ) by applying a laser welded joint,
the roller body ( 2 ), the adapter assembly (A), and the drive wheel ( 5 ) are provided with a zinc layer ( 2 ) on the surface,
wherein the drive wheel ( 5 ), the adapter assembly (A) and the roller body ( 2 ) are provided with the zinc layer before assembly, and
wherein by applying the laser welded joint, the zinc layer is only destroyed to such a small extent that its cathodic corrosion protection is retained.
