Abstract

Provided is an apparatus for transporting objects and in particular containers and/or liquid containers with a first conveyor device which is arranged at least temporarily below the objects to be conveyed and which conveys the objects, wherein the conveyor device includes a point device, and a feed section which conveys the objects to the point device, and wherein the objects are selectively conveyable along at least a first discharge section and a second discharge section by the point device, wherein the feed section extends substantially rectilinearly and wherein the first discharge section follows the feed section in a rectilinear manner and the second discharge section deviates from the rectilinear course of the feed section, and wherein the apparatus includes a selection tool for selectively conveying the objects onto the first discharge section or the second discharge section.

First claim

The invention claimed is:

1. An apparatus for transporting containers with a first conveyor device which is arranged at least temporarily below the containers and which conveys the containers, wherein the conveyor device comprises a point device, and a feed section which conveys the containers to the point device, and wherein the containers are selectively conveyable along at least a first discharge section and a second discharge section by the point device, wherein the feed section extends substantially rectilinearly and wherein the first discharge section follows the feed section in a rectilinear manner and the second discharge section deviates from the rectilinear course of the feed section, and wherein the apparatus comprises a selection tool for selectively conveying the containers onto the first discharge section or the second discharge section, wherein the selection tool comprises at least one contact device for urging the containers, the selection tool being switchable between a first state in which it does not influence the direction of movement of the containers and a second state in which it changes the direction of movement of the containers, wherein the point device comprises a conveyor device for conveying the containers, and wherein the conveyor device comprises a plurality of conveyor rollers, which conveys the containers located on these rollers, wherein the point device conveys the containers in the first state of the selection tool into the second discharge section and the contact device in a state in which the containers are not transported in a straight direction, is arranged above the transport path of the containers, wherein, in order to displace the containers along the rectilinear transport path, the contact device is displaced from top to bottom into the transport path of the containers.

2. The apparatus according to claim 1 , wherein the conveyor device conveys the containers along a curved transport path.

3. The apparatus according to claim 1 , wherein at least one conveyor path of the containers is determined by a geometry of the conveyor rollers.

4. The apparatus according to claim 1 , wherein one of these conveyor rollers or several of these conveyor rollers are driven.

5. The apparatus according to claim 1 , wherein one of these conveyor rollers or several of these conveyor rollers have a frustoconical cross-section.

6. The apparatus according to claim 1 , wherein two conveyor devices are connected to the point device in the transport direction of the containers.

7. The apparatus according to claim 1 , wherein the contact device is a flat urging element displaceable into the transport path of the containers.

8. The apparatus according to claim 1 , wherein the apparatus comprises at least one second point device, which is arranged in the transport direction after the first point device.

9. A method for transporting containers with a first conveyor device which is arranged at least temporarily below the containers to be conveyed and which conveys the containers, this conveyor device having a point device and a feed section, which conveys the containers to the point device and wherein the containers are conveyed by the point device selectively along at least a first discharge section or a second discharge section, wherein the feed section extends substantially rectilinearly and wherein the first discharge section adjoins the feed section in a rectilinear manner and the second discharge section deviates from the rectilinear course of the feed section, and wherein by a selection tool the containers are conveyed either to the first discharge section or the second discharge section, wherein this selection tool urges the containers by at least one contact device and wherein this selection tool is switched at least temporarily between a first state in which it does not influence the direction of movement of the containers and a second state in which it changes the direction of movement of the containers, wherein the point device conveys the containers in the first state of the selection tool into the second discharge section and the contact device in a state in which the containers are not transported in a straight direction, is arranged above the transport path of the containers, wherein, in order to displace the containers along the rectilinear transport path, the contact device is displaced from top to bottom into the transport path of the containers.

10. The apparatus according to claim 1 , wherein if the selection tool does not intervene, the containers are conveyed along a transport path that is curved or deviates from the straight direction.

11. The apparatus according to claim 1 , wherein the transport device is an active and driven transport device, so that the containers are actively conveyed.

12. The apparatus according to claim 11 , wherein the transport device is driven in the area of the second discharge section.

13. The apparatus according to claim 1 , wherein the contact device is an element or de-vice which contacts the containers in at least one area, wherein this contact causes a change in the transport direction of the containers.

14. The apparatus according to claim 13 , wherein the contact device is arranged laterally next to the transport path of the containers and contacts one side surface of the containers to be transported.

15. The apparatus according to claim 1 , wherein the contact device extends at least in sections along a rectilinear direction and a direction which is parallel to the direction of movement of the containers in the feed section and coincides with this direction of movement.

16. The apparatus according to claim 1 , wherein a number of contact devices are arranged one behind the other in the direction of movement of the containers.

17. The apparatus according to claim 16 , wherein at least 3 contact devices are provided.

18. The apparatus according to claim 1 , wherein the contact device pushes the containers into a straight-line transport.

19. The apparatus according to claim 1 , wherein the containers are selected from a group of containers that includes beverage crates, barrels, and shrink-wrapped containers.

20. The apparatus according to claim 1 , wherein the containers have a mass which is greater than 3 kg and less than 30 kg.
