Abstract

The invention relates to a drive device ( 1 ) for a conveyor carriage ( 4 ) of a conveyor device ( 2 ), comprising a drive source ( 6 ) for generating a drive force (FTr) and a drive force transmission device ( 8 ) for transmitting the drive force (FTr) to a drive surface of the conveyor carriage ( 4 ). The conveyor carriage ( 4 ) has at least one counter bearing element ( 12 ) in particular which is designed as a counter bearing for the drive force transmission device ( 8 ).

First claim

The invention claimed is:

1. A conveyor installation ( 2 ), comprising
at least one conveyor carriage ( 4 ) having a drive surface ( 10 ),
a drive device ( 1 ) adapted for at least temporarily driving the at least one conveyor carriage ( 4 ),
the drive device ( 1 ) comprising
a drive source ( 6 ) for generating a drive force (FTr), and
a drive force transmission installation ( 8 ) for transmitting the drive force (FTr) to the drive surface ( 10 ) of the conveyor carriage ( 4 ),
wherein the conveyor carriage ( 4 ) has a receptacle region ( 4 F), in particular a conveying surface ( 4 F), for receiving piece goods,
characterized in
that the at least one conveyor carriage ( 4 ) is adapted to release conveyed items downward by means of one or a plurality of flaps in the manner of a trapdoor,
that the drive surface ( 10 ) in a plan view and when viewed in the driving direction, is disposed laterally next to the receptacle region ( 4 F) and aligned so as to be horizontal.

2. The conveyor installation ( 2 ) as claimed in claim 1 , wherein the drive surface ( 10 ) and/or the conveyor carriage ( 4 ) by means of a counter bearing element ( 12 ) are/is supported in relation to a contact pressure force (FDr) of the drive force transmission installation ( 8 ).

3. The conveyor installation ( 2 ) as claimed in claim 1 , wherein the drive force transmission installation ( 8 ), when viewed in the conveying direction (RF), is disposed exclusively on a lateral side of the conveyor carriage ( 4 ).

4. The conveyor installation ( 2 ) as claimed in claim 1 , wherein the drive force (FTr) is able to be transmitted, or is transmitted, in a friction-fitting manner from the drive force transmission installation ( 8 ) to the drive surface ( 10 ).

5. The conveyor installation as claimed in claim 1 , wherein at least one counter bearing element ( 12 ) is configured as a roller and/or as a sliding element of the conveyor carriage ( 4 ).

6. The conveyor installation ( 2 ) as claimed in claim 1 , wherein at least one counter bearing element ( 12 ) is configured as a support roller ( 14 ) and/or as a guide roller ( 20 ) of the conveyor carriage ( 4 ).

7. The conveyor installation ( 2 ) as claimed in claim 1 , wherein a contact pressure force (FDr) of the drive force transmission installation ( 8 ) on the drive surface ( 10 ) is aligned so as to be substantially perpendicular to the drive surface ( 10 ).

8. The conveyor installation ( 2 ) as claimed in claim 1 , wherein the drive force transmission installation ( 8 ) has an effective drive surface ( 34 ) which is aligned so as to be substantially horizontal and is pressed onto the drive surface ( 10 ) by a contact pressure force (FDr) aligned so as to be substantially vertical.

9. The conveyor installation ( 2 ) as claimed in claim 8 , wherein the contact pressure force (FDr) is caused at least by means of the weight (FGw) of the drive force transmission installation ( 8 ).

10. The conveyor installation ( 2 ) as claimed in claim 1 , wherein the drive force transmission installation ( 8 ) has an effective drive surface ( 34 ) which is aligned so as to be substantially vertical and is pressed onto the drive surface ( 10 ) by a contact pressure force (FDr) aligned so as to be substantially horizontal.

11. The conveyor installation 2 ) as claimed in claim 1 , wherein the drive force transmission installation ( 8 ) has an effective drive surface ( 34 ) which is aligned in an angular position between the horizontal and the vertical and is pressed onto the drive surface ( 10 ) by a contact pressure force (FDr) aligned so as to be substantially perpendicular to the effective drive surface ( 34 ).

12. The conveyor installation ( 2 ) as claimed in claim 1 , wherein a contact pressure force (FDr) of the drive force transmission installation ( 8 ) is at least partially caused by means of a contact pressure installation ( 42 ).

13. The conveyor installation ( 2 ) as claimed in claim 1 , wherein the drive force transmission installation ( 8 ) has a drive belt ( 22 ) which is able to be pressed, or is pressed, onto the drive surface ( 10 ) by means of the contact pressure force (FDr).

14. The conveyor installation ( 2 ) as claimed in claim 1 , wherein the drive belt ( 22 ) is wrapped about two deflection rollers ( 24 , 26 ), wherein a contact pressure assembly ( 28 ) which is adapted for pressing the drive belt ( 22 ) onto the drive surface ( 10 ) by the contact pressure force (FDr) is provided between the two deflection rollers ( 24 , 26 ),
in particular wherein the contact pressure assembly ( 28 ) comprises one or a plurality of contact pressure rollers ( 28 ), and/or
in particular wherein the deflection rollers ( 24 , 26 ) do not serve for transmitting the contact pressure force (FDr) to the belt.

15. The conveyor installation ( 2 ) as claimed in claim 1 , wherein the conveyor installation ( 2 ) has a plurality of drive force transmission installations ( 8 ) which are disposed at predetermined mutual spacings.

16. The conveyor installation ( 2 ) as claimed in claim 1 , wherein a counter bearing element ( 12 ) is configured at a minimum spacing from an effective line of a contact pressure force (FDr) of the drive force transmission installation ( 8 ), said spacing being less than approximately 50 mm.

17. The conveyor installation ( 2 ) as claimed in claim 1 , comprising a drive force transmission installation ( 8 ) for the drive device ( 1 ), wherein the drive force transmission installation ( 8 ) is able to be introduced into a mounting ( 32 ) configured on the conveyor installation ( 2 ) and able to be locked therein.

18. The conveyor installation ( 2 ) according to claim 1 ,
wherein the drive device ( 1 ) is disposed so as to be stationary during operation.

19. The conveyor installation ( 2 ) as claimed in claim 18 ,
wherein the receptacle region ( 4 F) is a conveying surface ( 4 F).
