Abstract

A suspended conveyor includes a rail and a conveying means, which is movably mounted on the rail in a conveying direction and includes carriers, for releasable holding suspended transportation means. The suspended conveyor includes a special clearing arrangement for clearing at least a section of the rail of transport means. The clearing arrangement generally includes a clearing device, which is either movably arranged with a guide bearing along the rail section and includes a clearing element or is arranged in a fixed position. Furthermore, the clearing arrangement includes an actuating arrangement that is configured to move the clearing device from a standby state to a clearing state. In the clearing state, the clearing element is configured to release the transport means from the carriers in the rail section by a relative movement of the clearing device to the conveying means.

6 . The suspended conveyor ( 1 ) according to claim 5 , wherein the tilting device ( 13 ) is configured as a parallelogram and the at least one spring element ( 14 ) diagonally connects two corners of the parallelogram.

7 . The suspended conveyor ( 1 ) according to claim 4 , wherein a spring element ( 19 ) connects the clearing element ( 10 ) and the base ( 12 ), so that the clearing element ( 10 ) is pivotable from the standby position into the clearing position via a dead center and pivoting back is made more difficult.

8 . The suspended conveyor ( 1 ) according to claim 1 , wherein the clearing device ( 8 ) has a tilting device ( 13 ) which is arranged between the guide bearing ( 9 ) and the clearing device element ( 10 ) and is set up for this purpose, to move the clearing element ( 10 ) relative to the guide bearing ( 9 ) about a tilting axis (K) from a standby position to a tilting position, and in particular to tilt the base ( 12 ) about the tilting axis (K) when the clearing device ( 8 ) is moved from the standby state to the clearing state.

9 . The suspended conveyor ( 1 ) according to claim 8 , wherein a stop element ( 17 ) is arranged on the tilting device ( 13 ), which in the standby position abuts against a stop ( 18 ) fixed in relation to the rail section ( 7 ) in order to hold the clearing device ( 8 ) in a starting position and to release the movement of the clearing device ( 8 ) along the rail section ( 7 ) in the tilting position.

10 . The suspended conveyor ( 1 ) according to claim 1 , wherein the clearing element comprises a blade ( 10 ) with a release section ( 20 ) and a collecting section ( 21 ) adjacent thereto.

11 . The suspended conveyor ( 1 ) according to claim 10 , wherein the release section ( 20 ) has a contact contour, in particular an edge ( 22 ), which is aligned in the removal position of the blade ( 10 ) in such a way that it forms a slope towards the collecting section ( 21 ) for lifting the transport means ( 5 ) from the carriers ( 4 ) and/or that it forms an incline towards the collecting section ( 21 ) for moving the transport means ( 5 ) laterally away from the carriers ( 4 ), wherein the incline and the slope are preferably aligned in such a way that lifting and moving away of the transport means ( 5 ) from the carriers ( 4 ) take place in a superimposed movement.

12 . The suspended conveyor ( 1 ) according to claim 10 , wherein the collecting section ( 21 ) is formed as an indentation ( 23 ), the distal end of which is formed by one of a stop and a nose ( 24 ).

13 . The suspended conveyor ( 1 ) according to claim 1 , wherein the transport means ( 5 ) have hook-shaped holding means ( 25 ), and the transport means ( 5 ) are configured as clothes hangers and/or transport pockets.

14 . The suspended conveyor ( 1 ) according to claim 1 , wherein the clearing element ( 10 ) is arranged on a base ( 12 ) of the clearing device ( 8 ) so as to be pivotable about a pivot axis (S) between a standby position and a clearing position and wherein the clearing device ( 8 ) has a tilting device ( 13 ) which is arranged between the guide bearing ( 9 ) and the clearing device element ( 10 ) and is set up for this purpose, to move the clearing element ( 10 ) relative to the guide bearing ( 9 ) about a tilting axis (K), wherein the pivot axis (S) and the tilting axis (K) are arranged substantially perpendicular to each other and/or the pivot axis (S) and the tilting axis (K) are each arranged substantially perpendicular to the conveying direction (x).
