Abstract
A system for conveying flat products, such as folded newspapers. The products are received in imbricated formation on a first conveyor and passed to an intermediate or transfer conveyor, the receiving and of which is at a lower level than the discharge end of the first conveyor. The transfer conveyor accelerates the products to a conveyor which has gripping members that receive the leading edges of the products and which moves at a slower speed than the transfer conveyor. The acceleration of the products on the transfer conveyor assures that the leading edges are received within the gripping members.
Claims5
A system for conveying flat products, comprising:
- a first conveyor (4) for moving the products in imbricated formation,
- a second conveyor (14) having gripping members (12) thereon for gripping the products,
- a transfer conveyor (10) having a smooth surface for frictionally engaging products received from the first conveyor and successively delivering single ones of the products to the second conveyor by bringing the leading edges of the products into engagement with respective ones of the gripping members on the second conveyor as the products are moved past the delivery end of the transfer conveyor,
- sensor means (20) for detecting the leading edge of the products on the first conveyor,
- a speed adjustable driving unit (16) responsive to the sensor means for driving the transfer conveyor at a speed causing the arrival of the leading edges of the products at the second conveyor to coincide with the passage of the gripping members.
