Abstract

A transport device includes a first transport-element that comprises rotatable transport-element sections and that defines a transport path for transporting materials between front and rear deflection-devices. The path has successive sections along a transport direction and extends between drive-arrangements spaced apart along the transport path. The drive-arrangements interactively connect to the transport-element at different locations along the transport path. Rotatable transport-element sections are repositioned relative to one another in such a way to change an overall length of the first transport-element. Targeted controlling of adjacent transport path sections at a differential speed by way of the first and second drive-arrangements creates an accumulation or a gap of transport material on a transport-path section.

First claim

The invention claimed is:

1. An apparatus comprising a transport device for transporting materials in a transport direction, said transport device comprising a front deflection-device, a rear deflection-device, a first drive-arrangement, a second drive-arrangement, and a first transport-element that comprises rotatable transport-element sections and that defines a transport path between said front deflection-device and said rear deflection-device, wherein said transport path comprises a first transport-path section and a second transport-path section arranged in succession along said transport direction and extending between said first drive-arrangement and said second drive-arrangement, wherein said transport path transports said materials, wherein, as a result of being guided over said front deflection-device and said rear deflection-device, said first transport-element forms a closed loop around which said first transport-element circulates, wherein said first drive-arrangement and said second drive-arrangement cooperate to drive said first transport-element, wherein said first drive-arrangement and said second drive-arrangement are spaced apart from each other along said transport path, wherein said first drive-arrangement and said second drive-arrangement are interactively connected to said first transport-element at different locations along said transport path, wherein said rotatable transport-element sections are capable of being repositioned relative to one another to change an overall length of said first transport-element, and wherein said first and second drive arrangements are controlled to cause said first and second transport-path sections to move at different speeds to create one of an accumulation and a gap on one of said first and second transport-path sections.

2. The apparatus of claim 1 , further comprising a control unit, wherein said control unit is connected to said first drive-arrangement and to said second drive-arrangement, wherein said control unit provides coordinated control over said first and second transport-path sections.

3. The apparatus of claim 2 , wherein said control unit comprises a processor, storage, and an interface, said storage interacting with said processor and said interface providing a mechanism for communicating with said control unit.

4. The apparatus of claim 3 , wherein said processor is configured to execute a control routine for controlling said first and second drive-arrangements.

5. The apparatus of claim 3 , wherein said storage is configured for storage of measured control data and target control data, said measured control data including data indicative of speed, direction of rotation, angle of rotation, and a torque.

6. The apparatus of claim 3 , wherein said processor is configured to compare said measured control data with said target control data, said measured control data having been received through said interface, wherein said processor is further configured to modify said control routine to control said first and second drive-arrangements based on a comparison between said measured control data and said target control data.

7. The apparatus of claim 3 , wherein said processor is configured to determine measured control data based at least in part on a nominal current, wherein said nominal current is a current that is needed to operate one of said first and second drive-arrangements.

8. The apparatus of claim 3 , wherein said processor is configured to define a master drive and a slave drive, said master drive and said slave drive being selected from the group consisting of said first drive-arrangement and said second drive-arrangement.

9. The apparatus of claim 1 , wherein said first and second drive-arrangements comprise direct-drive electric motors.

10. The apparatus of claim 1 , wherein said transport path comprises a straight course.

11. The apparatus of claim 10 , wherein said straight course is disposed between said first and second drive-arrangements.

12. The apparatus of claim 1 , wherein said front and rear deflection-devices are formed by corresponding ones of said first and second drive-arrangements.

13. The apparatus of claim 1 , further comprising a second transport-element, wherein said first and second transport-elements are adjacent to each other, and wherein said first and second transport elements are arranged square to said transport direction.

14. The apparatus of claim 13 , wherein said second transport-element comprises at least a pair of drive-arrangements.

15. The apparatus of claim 13 , wherein said first and second drive-arrangements are common to said first and second transport-elements, whereby each transport element is driven by said first and second drive-arrangements.

16. The apparatus of claim 15 , wherein said second transport-element comprises rotatable transport-element sections that configured to rotate and to be repositioned relative to one another to change an overall length of said second transport-element.

17. The apparatus of claim 1 , wherein said first transport-element comprises a conveyor chain that comprises a plurality of chain links.

18. The apparatus of claim 1 , further comprising a processor configured to operate said first drive-arrangement with first target control data and to operate said second drive-arrangements with second target control data, wherein said first and second target control data differ from each other.

19. The apparatus of claim 18 , wherein said first transport-path section and said second transport-path section comprise a front transport-section and a rear transport-section, wherein material reaches said rear transport-section before reaching said front transport-section, wherein said processor is configured to control said front and rear transport-sections such that said front transport-section conveys at a higher speed than said rear transport-section.

20. The apparatus of claim 18 , wherein said first transport-path section and said second transport-path section comprise a front transport-section and a rear transport-section, wherein material reaches said rear transport-section before reaching said front transport-section, wherein said processor is configured to control said front and rear transport-sections such that said front transport-section conveys at a lower speed than said rear transport-section.

21. The apparatus of claim 1 , further comprising a control unit that provides coordinated control over individual transport path sections, wherein said control unit controls said first and second drive-arrangements based at least in part on target control data that is preset such that a third transport-path section is in a particular state, wherein said particular state is selected from the group consisting of a fully-extended state and a fully-retracted state, and wherein said third transport-path section is selected from the group consisting of said first transport-path section and said second transport-path section.

22. The apparatus of claim 1 , further comprising a control unit that provides coordinated control over individual transport path sections by controlling said first and second drive-arrangements based at least in part on target control data that is preset in such a way that changing a length of a third transport-path section occurs only after a change in length of a fourth transport-path section has been effected, wherein said third and fourth transport-path sections are selected from the group consisting of said first and second transport-path
