Buffer conveyor for conveying and buffering products
First Claim
1. A buffer conveyor for conveying and buffering products, comprising:
- a frame,at least one first elongated conveyor supported by the frame, which is driven in a first direction and which has a supply end,a second elongated conveyor supported by the frame, which is driven in a second, opposite direction and which has a discharge end, which first and second conveyors extend at least substantially parallel to each other,a transfer unit movable adjacent the first and second elongated conveyors, the transfer unit having a transfer device configured to transfer the products from the first conveyor to the second conveyor and a drive unit configured to move the transfer unit relative to the frame, wherein the drive unit comprises a drive motor providing power to move the transfer unit using a source of energy not due to movement of the conveyors, and wherein a position of the drive motor moves relative to the frame at least partly when the transfer unit moves relative to the frame.

Abstract
A buffer conveyor for conveying and buffering products comprises a first elongated conveyor and a second elongated conveyor that can be driven in an opposite direction. The first and the second conveyor extend in a path at least substantially parallel to each other and beside each other. A transfer unit is movable at least substantially parallel to the first and the second conveyor in the aforesaid path and is provided with a transfer device for transferring the products from the first conveyor to the second conveyor. The transfer unit comprises a drive unit for moving the transfer unit, preferably in dependence on the velocities of the first and the second conveyor.
The drive unit of the transfer unit comprises a drive motor, which follows the movements of the transfer unit at least in part.
