Bearing mount for a worm guide bar
A device for transferring sausage-shaped products, carried out of a clipping machine and provided with loop-shaped suspension elements, to a product receiving element, said device containing: a guide bar along which the suspension elements can be guided in the direction of transport by means of conveyor elements, and a front and a rear bearing assembly for the guide bar, the bearing assemblies having a right-hand and a left-hand bearing unit that are each disposed in pairs laterally from the guide bar. It is further provided that the front and rear bearing assemblies form drivable positive guidance mechanisms for the suspension elements.
1. A device for transferring sausage-shaped products that are carried out of a clipping machine and provided with loop-shaped suspension elements, to a product receiving element, the device comprising:
a guide bar along which the suspension elements are guided in a direction of transport by conveyor elements;
front and rear bearing assemblies for the guide bar, the bearing assemblies having a right-hand and a left-hand bearing unit in each case are disposed in pairs laterally from the guide bar;
the front and the rear bearing assemblies form drivable positive guidance mechanisms for the suspension elements;
the right-hand and left-hand bearing units of the front and rear bearing assemblies each have at least one support bearing element and two counter bearing elements;
the support bearing element of one bearing unit is formed by a drivable support shaft, the axis of which extends substantially parallel to the direction of transport;
the support bearing elements of the two right-hand and of the two left-hand bearing units of the front and rear bearing assemblies are each formed by a common support shaft.
2. The transfer device of claim 1 , wherein the positive guidance mechanism for the suspension elements is formed by a guide gap defined between mutually contacting and rotating bearing elements of the bearing units.
3. The transfer device of claim 2 , wherein at least the mutually contacting surface sections of the bearing elements of the bearing units have a high friction coefficient at least in sections thereof.
4. The transfer device of claim 1 , wherein at least one part of the bearing elements of the bearing units is provided at its outer circumference with at least one circumferential groove extending in the form of a thread in the direction of transport.
5. The transfer device of claim 1 , wherein the central longitudinal axis of the support bearing element and the central longitudinal axis of the two counter bearing elements of a bearing unit are arranged in relation to one another in such a way that, when viewed in a plane perpendicular to the direction of transport, they span a triangle.
6. The transfer device of claim 5 , wherein the two counter bearing elements of a bearing unit are arranged one above the other, when viewed in a plane perpendicular to the direction of transport.
7. The transfer device of claim 1 , wherein the counter bearing elements of a bearing unit are formed by counter bearing shafts which rotate about their central longitudinal axis.
8. The transfer device of claim 1 , wherein the axes of the counter bearing shafts extend substantially parallel to the direction of transport.
9. The transfer device of claim 1 , wherein the support bearing element is disposed laterally from and between the two counter bearing elements, when viewed in a plane perpendicular to the direction of transport.
10. The transfer device of claim 1 , wherein the support shafts of the right-hand and left-hand bearing units are driven synchronously and in opposite directions by a preferably common drive unit.
11. The transfer device of claim 1 , wherein the support bearing element of a bearing unit has a convex protuberance or a concave recess at its outer circumference.
12. The transfer device of claim 11 , wherein the counter bearing element of a bearing unit is provided at its outer circumference with a configuration in the form of a concave recess or convex protuberance corresponding to the convex protuberance or to the concave recess of the support bearing element and mutually engaging therewith.
13. The transfer device of claim 1 , wherein the first and the second bearing units are arranged opposite one another on side surfaces of the guide bar.
14. The transfer device of claim 1 , wherein the guide bar is a beam with preferably rectangular cross-section.
15. The transfer device of claim 14 , wherein the front and the rear bearing assemblies each engage two side surfaces of the beam.
16. The transfer device of claim 1 , wherein the guide bar is provided with recesses positioned one after the other in the direction of transport on both sides of the guide bar.
17. The transfer device of claim 16 , wherein the recesses are arranged transversely to the direction of transport and opposite one another on the side surfaces of the guide bar.
18. The transfer device of claim 16 , wherein the at least two counter bearing elements of a bearing unit are each disposed inside one recess of the guide bar.
19. The transfer device of claim 17 , wherein the counter bearing element extends over the entire length of the recess.
20. The transfer device of claim 1 , wherein the guide bar has at least one groove on its upper side and extending over its entire length.
21. The transfer device of claim 1 , wherein the guide bar has receiving means at its ends for connecting additional devices.
22. The transfer device of claim 1 , wherein the two counter bearing elements of a bearing unit are arranged one above the other, when viewed in a plane perpendicular to the direction of transport.
