Abstract
A roller conveyor is designed for transferring a load from a departure station where the load sets off to an arrival station where it is stopped by a buffer. The latter comprises a stop plate mounted on a shock absorber associated with a position detector, to ensure that the load and its support are stopped in the correct position and that they are displaced from the arrival station of the conveyor towards the departure station of another conveyor.
Claims3
A computer- or coder-controlled load handling installation, such as roller conveyor equipment designed to transfer a load from a departure station from which the load sets off to an arrival station at which the load is stopped, comprising:
- (a) a buffer assembly at said arrival station for smoothly stopped said load as the load reaches the arrival station, said buffer assembly including a fixed support and a yieldable stop plate adapted to be engaged by said load upon its arrival at said arrival station;
- (b) a shock absorber including spring means and damping means and a position sensor associated with the shock absorber on which said stop plate is mounted,
- wherein said shock absorber and said position sensor each includes a telescopic apparatus operatively involving a pneumatic spring device, and
- wherein said buffer assembly is adapted to bring said load to a smooth stop, is responsive to the position of said stop plate detected by the position detector which emits a signal when said stop plate is in a predetermined position for disposal of said load;
- and
- (c) load disposal means under the control of said position sensor for shifting said load from said arrival station of said conveyor to a second departure station of a further conveyor.
