Abstract

A transfer device, adapted to convey an object in a conveying direction, and selectively transfer an object in a second direction angled to the conveying direction; the transfer device having a plurality of belt carriers, circumferentially running along the transfer device, a traction belt circumferentially running along the transfer device, along which the plurality of belt carriers is arranged; circumferentially running transfer belts forming an upper run and a lower run; wherein each belt carrier carries a transfer belt, which protrudes above the belt carrier, and wherein the plurality of transfer belts is defining a conveying plane, on which the object comes to rest during conveying; wherein for laterally transferring the object the transfer belts are selectively driven. The transfer device also has a tensioner, which is adapted to change the tension of the traction belt.

First claim

What is claimed is:

1 . A transfer device ( 20 ), adapted to convey an object ( 9 ) in a conveying direction (FR), and selectively transfer an object ( 9 ) in a second direction (A) angled to the conveying direction (FR), the transfer device ( 20 ) comprising:
a plurality of belt carriers ( 21 ), circumferentially running along the transfer device ( 20 ), a traction belt ( 27 ) circumferentially running along the transfer device ( 20 ), along which the plurality of belt carriers ( 21 ) is arranged; a tensioner ( 7 ), which is adapted to change a tension of the traction belt ( 27 ); circumferentially running transfer belts ( 24 ) forming an upper run ( 273 ) and a lower run ( 274 ); wherein each belt carrier ( 21 ) carries a transfer belt ( 24 ), which protrudes above the belt carrier ( 21 ), and wherein the plurality of transfer belts ( 24 ) defines a conveying plane (FE), on which said object ( 9 ) comes to rest during conveying; wherein for laterally transferring the object ( 9 ) the transfer belts ( 24 ) are selectively driven; wherein the tensioner ( 7 ) comprises a force limiter ( 75 ), limiting tensioning force (P) which is applied by a force storage ( 72 ) to the traction belt ( 27 ); and wherein a distance holder ( 72 ) and/or the force limiter ( 72 ) is adapted to bridge a length of a spring ( 27 ).

2 . The transfer device ( 20 ) according to claim 1 , characterized in that the tensioner ( 7 ) comprises the force storage ( 72 ), in particular the spring ( 72 ), which is adapted to provide the tensioning force (P).

3 . The transfer device ( 20 ) according to claim 1 , characterized in that the traction belt ( 27 ) is wound around two deflection wheels ( 291 , 292 ), and that the tensioner ( 7 ) comprises the distance holder ( 75 ), wherein the distance holder ( 75 ) is adapted to ensure a minimum distance between said two deflection wheels ( 291 , 292 ).

4 . The transfer device ( 20 ) according to claim 1 , characterized in that the distance holder ( 72 ) is the force limiter ( 72 ).

5 . The transfer device ( 20 ) according to claim 3 , characterized in that the distance holder ( 72 ) and/or the force limiter ( 72 ) is a bushing, located coaxially around the spring ( 72 ).

6 . The transfer device ( 20 ) according to claim 1 , characterized in that the transfer device ( 20 ) is able to selectively operate the traction belt ( 27 ) in two directions (R 1 , R 2 ), in particular, the traction belt ( 27 ) can selectively be driven in a manner, that in a first operation mode a driven wheel ( 291 ) pulls the upper run 273 (direction R 1 ) and that in a second operation mode a driven wheel ( 291 ) pulls the lower run ( 274 ) of the traction belt ( 27 ).

7 . The transfer device ( 20 ) according to claim 6 , characterized in that the transfer device ( 20 ) comprises a plurality of deflection wheels ( 291 , 292 ) for deflecting the traction belt ( 27 ), wherein all deflection wheels ( 291 , 292 ) deflect the traction belt inwardly.

8 . The transfer device ( 20 ) according to claim 7 , characterized in that the plurality of the deflection wheels ( 291 , 292 ) comprises exactly two deflection wheels ( 291 , 292 ) per traction belt ( 27 ).

9 . Use of a transfer device ( 20 ) according to claim 8 , wherein for adjusting the tension of the traction belt ( 27 ) the tensioner ( 7 ) is operating in a manner that after the belt tension is adjusted correctly the distance holder and/or the force limiter ( 75 ) is held with play.
