BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a method and apparatus in a plant including at least two insertion machines, for coordinating product streams from the machines, the streams in turn having been branched off from a stream of newspapers coming from a newspaper printing press, to a single stream of newspapers having the same speed as the one coming from the press.
In daily newspaper printing houses, it is becoming routine to insert preprinted supplements or advertising materials into the newspaper for distribution in conjunction with delivery of the newspapers. Insertion machines are used for this purpose. The insertion machines are designed such that the printed material can be placed between the pages of the ordinary newspaper. The disadvantage with presently available insertion machines is that their capacity is considerably less than the capacity of newspaper printing presses. This means that several insertion machines must be used in parallel to obtain a production rate which is as large as that of the newspaper press in order not to increase production times. Also conventionally a flow of collated products is obtained from each of the insertion machines, and each machine requires its own stacking and bundling line. As a result a large space and extra personnel are required.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention is to provide a method and apparatus which alleviates the increased costs associated with the problem described above. The invention provides that two or more streams of newspapers from insertion machines, one stream per machine, are combined, to form a single uniform stream of newspapers which moves along at the same speed as that of the newspaper stream from the press with the aid of a coordinating conveying means including a reception conveyor and a transverse collecting conveyor, that the newspapers from the respective insertion machine being deposited in predetermined positions on the reception conveyor such that the stream from a first insertion machine is taken to the starting end of the conveyor and the remaining streams in turn to successive positions along the conveyor, the centre line of the respective stream being displaced a predetermined distance laterally relative the conveyor, for providing overlapping of the newspapers separately deposited from the different streams across the conveyor, that consecutive batches consisting of one newspaper from each stream conveyed on the conveyor thereafter are fed out to the collecting conveyor at 90.degree. to the reception conveyor, the conveying speeds of the two conveyors being mutually synchronized, and that each of the different batches is deposited on the last newspaper of a batch previosly deposited on the collecting conveyor and with the same displacement as the spacing of the newspapers in each batch, for thus providing a uniform stream of newspapers.
BRIEF DESCRIPTION OF THE DRAWING
The invention is described in detail below, with reference to the accompanying drawing, in which an apparatus in accordance with the present invention is illustrated.
DETAILED DESCRIPTION OF THE DRAWING
As schematically illustrated on the drawing, a stream 5 of newspapers coming from a newspaper printing press 4 is divided into three branch streams 6, 7, 8 in known manner. The branch streams 6, 7, 8 are directed to three insertion machines 9, 10, 11. After the newspapers are handled at the respective insertion machine 9, 10, 11 the branch streams 6, 7, 8 continue to move along to a reception conveyor 12. The processed newspapers 1, 2, 3 from the respective machine 9, 10, 11 are deposited on the conveyor 12, each separate newspaper 1, 2, 3 assuming a given position. The original relative positions of the newspapers 1, 2, 3 thus remains synchronized in the different streams 6, 7, 8. The individual newspapers 1, 2, 3 may be positioned completely separate from each other, for example. The synchronized streams 6, 7, 8 are directed in known manner, to the reception conveyor 12, which
