Abstract

The invention relates to a conveyor device with at least one first and second conveyor carriage which are arranged one behind the other in the conveyor direction (F), a cross belt conveyor which is formed on at least the second conveyor carriage for conveying material to be conveyed in a cross conveyor direction (Q) oriented substantially transversely to the conveyor direction (F), and a powertrain brake for the cross belt conveyor. An operating device is arranged on the first conveyor carriage and a brake device is arranged on the second conveyor carriage. The brake device assumes the release state when the first and second conveyor carriage are traveling in a substantially straight manner, and the brake device assumes the brake state when at least one of the conveyor carriages is cornering in order to allow a movement of a cross belt of the cross belt conveyor in a cross conveyor direction (Q) when traveling in a straight manner and brake the movement when cornering.

First claim

The invention claimed is:

1. A conveying device having:
at least one first and one second conveying carriage which are arranged one behind the other in a conveying direction,
a transverse-belt conveyor which is formed on at least the second conveying carriage and which serves for conveying material for conveying in a transverse conveying direction oriented substantially transversely with respect to the conveying direction, and
a drivetrain brake for the transverse-belt conveyor,
wherein the drivetrain brake has a brake apparatus and an operating apparatus for the brake apparatus, wherein the operating apparatus is arranged on the first conveying carriage and the brake apparatus is arranged on the second conveying carriage,
wherein the brake apparatus can be placed into a braking state in which the brake apparatus exerts a braking force on an element of a drivetrain of the transverse-belt conveyor, and can be placed into a release state, in which the brake apparatus exerts no or a reduced braking force on an element of a drivetrain of the transverse-belt conveyor,
wherein the operating apparatus and the brake apparatus interact such that, during substantially straight-ahead travel of the first and second conveying carriage, the brake apparatus assumes the release state and, during travel of at least one of the conveying carriages around a curve, the brake apparatus assumes the braking state, in order to allow a movement of a transverse belt ( 16 ) of the transverse-belt conveyor in the transverse conveying direction during straight-ahead travel and to brake such a movement during travel around a curve.

2. The conveying device as claimed in claim 1 , wherein the first conveying carriage with the operating apparatus arranged thereon is arranged so as to travel ahead, in the conveying direction, of the second conveying carriage with the brake apparatus.

3. The conveying device as claimed in claim 1 , wherein the brake apparatus has a first brake lever with a first friction element arranged thereon, wherein the first brake lever is mounted pivotably on the second conveying carriage and wherein, in the braking state of the brake apparatus, the first brake lever is pivoted such that the first friction element is pressed against the element of the drivetrain.

4. The conveying device as claimed in claim 3 , wherein the drivetrain brake has at least one elastic element, by means of the spring force of which the first brake lever is pivoted in the braking state.

5. The conveying device as claimed in claim 4 , wherein the elastic element is preloaded within a component of the brake apparatus.

6. The conveying device as claimed in claim 3 , wherein the element of the drivetrain is a counterpressure roller for a friction roller for driving the transverse belt.

7. The conveying device as claimed in claim 3 , wherein the first brake lever is attached with exactly one rotational degree of freedom, about a vertical axis (H) which is oriented perpendicular to the conveying direction and perpendicular to the transverse conveying direction, and without a translational degree of freedom, to the second conveying carriage.

8. The conveying device as claimed in claim 3 , wherein the first brake lever is pivotable by means of the operating apparatus into the braking state and/or into the release state.

9. The conveying device as claimed in claim 3 , wherein the drivetrain brake is configured such that the brake apparatus is placed into the braking state by means of the operating apparatus in the presence of a transverse offset and/or angular offset of the conveying carriages with respect to one another.

10. The conveying device as claimed in claim 3 , wherein the drivetrain brake is configured such that the operating apparatus places the brake apparatus into the release state in the absence of a transverse offset and angular offset of the conveying carriages with respect to one another.

11. The conveying device as claimed in claim 3 , wherein the brake apparatus has, in addition to the first brake lever, a second brake lever with a second friction element arranged thereon, wherein, preferably, the first brake lever is formed as a single piece with the second brake lever, and wherein the brake levers are arranged on mutually opposite sides of the element of the drivetrain.

12. The conveying device as claimed in claim 1 , wherein the operating apparatus has one or more operating elements which is or are attached with in each case at least two rotational degrees of freedom, about the vertical axis and about the transverse conveying direction, and with exactly one translational degree of freedom, which in the release state is oriented approximately parallel to the conveying direction, to the first conveying carriage.

13. The conveying device as claimed in claim 1 , wherein the operating apparatus has an operating element which is attached without a degree of freedom to the first conveying carriage.
