Abstract

A device or apparatus for collecting printed matter in a pile and delivering the pile to a conveyor at the same high speed as the output rate of a modern printing machine. A collecting basket can be rotated 180.degree. to enable alternate piling of folded printing matter to keep the piles even. The bottom of the collecting basket is a roller conveyor. To achieve high speed operation, the lateral opening in the collecting basket has two swing gates and the collecting basket is supported on a laterally reciprocable sled. From a starting position, where the basket is in position for collecting newspapers, a motor can move the sled, with the basket, at a sufficiently high speed horizontally through a relatively short distance to a stop position, at which position the lateral opening of the collecting basket is open because of outward swing movement of the two swing gates. The stop position is adjacent a belt conveyor at the same level as the basket bottom roller conveyor. The high speed of the sled, and thus also of the pile of newspaper, gives the pile a kinetic energy and when the sled and thus the basket are stopped the pile moves out along the basket bottom roller conveyor and out onto the belt conveyor which moves in the same direction and at the same speed. The basket can have two side openings each with swing gates and the sled can be moved in either direction to discharge a pile onto one or the other of a pair of belt conveyors at opposite stop positions of the sled.

Dependent claims

A device with a collecting basket for collecting printed matter, particularly newspapers, in the form of a pile and for discharging the pile through a lateral opening in the collecting basket, the bottom of said collecting basket comprising a freely movable conveyor having its direction of conveying movement aligned with the lateral opening in the basket, said device being characterized in that:

said basket includes two mechanically controlled outwardly movable swing gates adjacent said lateral opening for selectively closing said opening and means connected to said gates for selective opening and closing of said gates;
a laterally reciprocable sled means;
means mounting said basket on said sled means for reciprocation therewith;
power means connected to said sled means to reciprocate said sled means and basket laterally in a direction aligned with the direction of free movement of the basket bottom conveyor from a starting position, where said basket is positioned with the swing gates closed for collecting the printed matter, through a relatively short distance to a stop position and in which stop position the said swing gates are in an open condition;
and a horizontal conveyor located with its input adjacent said stop position at substantially the same level as said basket bottom conveyor, so that a pile of printed matter, carried by said basket during lateral reciprocation of the sled means from the start position to the stop position, will by its own inertia move along the basket bottom conveyor out through the lateral opening and over onto the horizontal conveyor.
