Abstract

A transport device having a screw conveyor for transporting products hanging on loops, in particular for transporting sausage products, the transport device includes a first screw conveyor section, a drive for the first screw conveyor section, wherein the drive torque is transferred to the screw conveyor section via an outer circumferential area of the first screw conveyor section, and further includes a first bearing assembly for the first screw conveyor section, wherein a second screw conveyor section that immediately adjoins the first screw conveyor section in the direction of transport is provided.

Claims (30)

1. A transport device having a screw conveyor for transporting products hanging on loops comprising:

a first screw conveyor section;

a drive operatively connected to the first screw conveyor section wherein drive torque is transferred to said first screw conveyor section via an outer circumferential area of the first screw conveyor section;

a first bearing assembly supporting the first screw conveyor section;

a second screw conveyor section immediately adjoining the first screw conveyor section in the direction of transport; and

the first screw conveyor section and the second screw conveyor section are hollow shafts,

wherein a right-hand end of the second screw conveyor section is inserted into a left-hand end of the first screw conveyor section.

2. The transport device of claim 1 , wherein a central longitudinal axis of the second screw conveyor section has an angular deviation with respect to a central longitudinal axis of the first screw conveyor section.

3. The transport device of claim 2 , wherein the central longitudinal axis of the first and second screw conveyor sections are arranged in an at least approximately vertical plane.

4. The transport device of claim 2 , wherein the angular deviation is less than 90°.

5. The transport device of claim 2 , wherein the angular deviation may be in any direction different to the direction predefined by the central longitudinal axis of the first screw conveyor section.

6. The transport device of claim 1 , wherein the first screw conveyor section includes a second bearing assembly.

7. The transport device of claim 6 , wherein the second screw conveyor section includes at least one bearing assembly.

8. The transport device of claim 7 , wherein the bearing assemblies of the first screw conveyor section and of the second screw conveyor section are each formed by three support wheels.

9. The transport device of claim 8 wherein the support wheels of each bearing assembly arranged at a uniform distance from each other in the circumferential direction of the screw conveyor sections.

10. The transport device of claim 1 , wherein the second screw conveyor section is capable of being be driven.

11. The transport device of claim 10 , wherein drive torque is transferred to the second screw conveyor section via an outer circumferential area thereof.

12. The transport device of claim 10 , wherein the second screw conveyor section is driven in synchrony with the first screw conveyor section.

13. The transport device of claim 10 , wherein the first and the second screw conveyor sections are jointly driven by the drive.

14. The transport device of claim 10 , wherein drive torque is transferred to the first and to the second screw conveyor sections by a respective support wheel.

15. The transport device of claim 14 , wherein each support wheel is in positive engagement with the first screw conveyor section and with the second screw conveyor section respectively.

16. The transport device of claim 14 , wherein each support wheel frictional engages the first screw conveyor section and the second screw conveyor section respectively.

17. The transport device of claim 14 , wherein the support wheels are connected by a Cardin shaft for synchronous transfer of the drive torque.

18. The transport device of claim 1 , wherein the first and the second screw conveyor sections are disposed rotatably and coaxially on a first axle section and a second axle section respectively.

19. The transport device of claim 18 , wherein the first and the second axle sections are fixedly connected to each other by a transition piece.

20. The transport device of claim 1 , wherein feed and discharge guides for the loops are provided at infeed and discharge ends of the transport device, respectively.

21. The transport device of claim 1 , wherein a run-out for the products is disposed in the region of the first screw conveyor section.

22. The transport device of claim 21 , wherein the run-out has a drivable conveyor belt.

23. The transport device of claim 22 , wherein a second section sloping downward in the direction of transport adjoins a first, horizontally oriented section of the conveyor belt.

24. The transport device of claim 21 , wherein the run-out is connected to a machine frame pivotably in relation to the first and second screw conveyor sections by means of an articulated joint.
