DESCRIPTION:
BRIEF SUMMARY
The present invention relates to an apparatus for bundling sheets or fascicles which are supplied one by one and are arranged in a regular loose bundle with the flat sides towards one another.
The invention has come about particularly for the handling of so-called signatures in the production of weekly magazines and similar printed products. The usual thing today is for the signatures to be delivered from the printing press in an upright stack which is then lifted manually into the so-called station stapler where the signatures are assembled and stapled. The object of the invention is to eliminate this manual handling, which is both hard and tiring, and to render possible an effective mechanical transfer of the signatures from the printing press to the station stapler.
For this purpose, an apparatus has been created for bundling sheets or fascicles, which are supplied one by one and are arranged in a regular loose bundle with the flat sides towards one another, comprising a bundling position for building up the loose regular bundle of sheets or fascicles supplied, a strapping position disposed at the side of the bundling position, in parallel therewith, in the longitudinal direction of the bundle, means for displacing a bundle in the transverse direction thereof from the bundling position to the strapping position, means for feeding a band or the like in the longitudinal direction thereof to the strapping position, means for guiding the band in a loop round the bundle in the strapping position and means for sealing a loop of band laid round the bundle in the strapping position, said apparatus having obtained the characteristics which can be seen from claim 1.
In order to illustrate the invention, this will be described in more detail below with reference to the accompanying drawings which show one embodiment of the apparatus according to the invention and in which
FIG. 1 is a general view in perspective of the apparatus,
FIG. 2 is an enlarged perspective view, partially broken away, of the strapping position in the apparatus,
FIG. 3 is a fragmentary perspective view of means for sealing the band which is laid round the bundle in the strapping position, shown in the empty state, and
FIG. 4 is a view corresponding to FIG. 3 but with a band in position for sealing.
In FIG. 1, to which reference is first made, a conventional conveyor 10 is shown for delivering printed products from a printing press, which are designated by 11 and in the present case are assumed to be signatures for a weekly magazine or the like. The signatures overlap one another partially on the conveyor but at the end portion 12 thereof, separation of the signatures is brought about and they are delivered from the end portion in a substantially vertical path.
The apparatus according to the invention is associated with the end portion 12 of the conveyor 10 to receive the signatures 11 one by one and comprises a stand 13 with a table top 13A on which a bundling position is disposed following immediately on the end portion 12, and a strapping position is disposed at the side of the bundling position.
The bundling position comprises an endless conveyor 14 with a plurality of mutually separated supports 15 disposed thereon. This conveyor has one run accommodated in the table top 13A, and the signatures 11 are delivered in an upright position to this run of the conveyor 14 which is driven in pace with the conveyor 10 to displace the supports 15 as the bundle grows. The bundle is straightened by means of a rail 16 which extends along the conveyor 14 at one side thereof and is mounted for movement in the transverse direction of the bundle by means of bars 17 which are displaceably received in roller guides 18 on the stand 13. The rail 16 is displaceable by means of a double-acting pneumatic cylinder 19 which is mounted on the stand by means of a bracket 20.
Each bundle which is formed in the bundling position should begin and end with a stiff panel 21, and a plurality of such panels are disposed in a magazine 22 on a bracket 23 on the stand 13. The
