Hoe & Co. Inc., New York, N. Y., acorporation of New York Application July 19, 1946, Serial No. 684,877 In Great Britain July 20, 1945 11 Claims.

This invention relates to improvements in delivery mechanism for machines such as printing machines the products of which pass from the machine in regular succession.

It is common at the present time to cause the products of a .printing machine to be forwarded from the machine in counted batches; it is usual for the counting to be effected by displacing at count intervals a count copy in a continuous stream of copies although proposals have been made to deliver the copies in separated stacked batches. In any case it is general for the products to pass along with their folded edges all having the same orientation and it is the usual practice for an operator stationed (either in the press room or, in the case of an extended delivery, in the publishing room) to take one counted batch and reverse it and then to assemble that batch with the following batch, the two batches being taken together and distinguished from one another by the reversed direction of the folded edges of one batch as compared with those of the other batch.

Nowthe main object of this invention is to provide improved mechanism by which this operation by the operator shall be dispensed with i. e. to provide mechanism by which the products of a printing or other like machine shall be delivered in bundles consisting of two (or more) batches distinguished within the bundle by different orientations of the folded edges.

According to this invention, there is provided mechanism which collects counted stacked batches of products and which assembles them in bundles consisting of two (or more) batches, the mechanism operating to re-orient or turn one batch with respect to another batch so that they are distinguished in the bundle from one another.

It is preferred that the products as they issue from a printing or like machine shall be diverted at count intervals from one path to another preferably by the switch device described in a pending application Serial No. 668,247 and in such a case the mechanism of this present invention would preferably operate to collect, into counted batches, the products passing respectively along the different paths, and to assemble the different batches to form the bundle with a movement which involves turning the batches (in the plane of the products) through an angle relatively to one another, the assembling of one batch with another providing the multi-batch bundle and the relative turning of the batches distinguishing one batch from another in the collected bundle.

In one arrangement, as applied to the mechanism described in the specification of application No. 668,247, the switch device described in that specification operates to direct a succession of counted products first to one travelling horizontal endless conveyor and then to another similar conveyor at different level from the first.

At the end of one conveyor (preferably the lower one) is a receiving platform which is movable through 180 between the position in line With that conveyor to a position'at the side of the other or upper conveyor; the platform is-held in position in line with its associated lower conveyor to receive and collect as a stacked batch the products passing along that conveyor in a counted stream and then (while the succeeding batch is passing to or along the upper conveyor) the platformis swung through 180 in the plane-of the products to bring that stacked batch to the side of the upper conveyor. During this time, the products passing along with the upper conveyor have been collected (preferably against a stop plate on a tray) to form a second stacked batch so that at this time there are provided two stacked batches side by side (regarded in the sense of travel of the conveyors) but with the folded edges of the products of one batch displaced through l with respect to the batch on the tray.

It is now only necessary to displace the batches relatively to superpose them in a collecting position and to collect them to form the required two batch bundle in which the two batches are distinguished.

It would be preferable to displace the second batch transversely from the tray (i. e. to move the batch transversely across the upper conveyor by which it was conveyed from the printing machine) the displacement being such that the batch is positioned over the other batch which is or had been on the platform.

The collection of the batches can be effected by a further vertical conveyor arranged at the side of the position which is occupied by the superposed batches; the conveyor has lateral arms which (as the conveyor moves) passes through the zone occupied by the batches and so receives them as an assembled bundle. It would be preferable to slot the platform so that the arms can pass through it and it is also preferable to arrange that the platform shall have a rising motion as it is turned to collecting position, this rising motion being such that the platform lifts the batch on it to above the level of the appropriate arms but below the level at which the other batch is displaced transversely, the platform then returning through the arms with a descending motion thus leaving its batch on the arms, the continued movement of which causes the batch on the arms to lift or take-away the batch which has by this time been displaced transversely from the second conveyor to the collecting position.

If desired, the platform may deposit its batch on a slotted table and the other batch is transferred to lie on that batch sothat as the conveyor arms move up they take the collected batches from the table. Adjustment of the parts for products of varying thickness can be provided for and also of course to accommodate a greater number of products than two.

The transverse displacement of the batch from the second conveyor can be effected by conveyor wires between which the collecting arms can move.

The invention is illustrated in the accompanying drawings in which Figure 1 is a sectional side elevation taken on the line I-I of Figure 3, Figure 2 an end elevation looking in the direction of the arrows II of Figure 3, Figure 3 a plan view and Figure 4 a sectional View taken on the line IVIV of Figure 1 of part of the mechanism and drawn to a larger scale.

Referring to the drawings, there are provided upper and lower conveyor belts or wires I, 2 which are carried by guide rollers 3, the wires I, 2 being driven so that their upper runs pass from left to right as seen in Figure 1. These conveyors act to convey counted batches of products from the delivery of a printing machine, a counted batch being fed first to one conveyor and then to the other conveyor for which purpose the switch device described and claimed in the pending application No. 668,247 could be employed.

The products of the batches would lie on the conveyors in overlapping relationship and to arrange these products in stacked batches there is associated with each conveyor a receiving platform on to which the conveyors discharge the products to build-up the stacked batch. The platform of the conveyor I is indicated at 5 and is constituted by sets of slats 6 (Figure 2), carried on endless chains l two such sets being employed and which are alternately brought into operation; stops 8 are provided up to which the products are fed by the conveyor I and which operate to register the successive products on the platform and to assist in the build-up of the counted batch.

The platform for the conveyor 2 is constituted by fingers 9 extending from a supporting frame ID, the fingers having end stop portions I I against which the products of a batch on the conveyor 2 are pressed to build-up the stack on the platform 9.

With the mechanism so far described a counted batch will be delivered to and stacked on one platform and then on the other platform and the stacked batches will have the same orientation i. e. assuming for example that the products are passing along the conveyors I, 2 with their :folded edges leading, both stacked batches would be in the same sense with their folded edges at the same side of the stack.

In order now to re-arrange one batch with respect to the other so that they can be collected with their folded edges having different orientations, one of the batches is turned in the plane of the products before the collection is effected. For this purpose, the platform 9 is arranged to Ill 4 be angularly displaced and this operation is effected during the time that the other [batch is being built up on one or the other sets of slats of platform 5. The frame I0 supporting the platform 9 is secured to a vertical tubular post I2 which is arranged to be turned intermittently through first in one direction and then back by a shaft I3 (Figure 1), on which the post I2 can slide axially while being held against relative rotation with respect to it; the shaft I3 has a pinion I l (Figure l) secured to it and the pinion meshes with a sector gear I5 mounted to rock on a post I6. This sector is provided with a cam bowl Il extending into a box-cam I8 rotatable on the shaft I3 and driven continuously by a worm I9 on a shaft 29, the shaft being itself driven by a gear 2| on 'a driving shaft 22 driven by some part of the printing machine. The cam I8 is formed with two operating parts I8, I8 and a dwell part I8 and the parts are so arranged that while the platform 9 is receiving its products, the bowl I! is in the dwell I8 after which the continued rotation of the cam presents to the bowl first one operating part I8 to move the platform from its receiving position through 180 and then the part I8 to return the platform to its receiving position.

In order to take the turned batch from the platform ll and hold it in readiness to be associated with the batch being built up on the platform 5, there is provided a stationary holding platform '24 (Figure 3), onto whichthe platform 9 lays its batch; this platform 24 is so positioned in relation to the platform 5 that the batch on the platform '5 can pass without change of height on to the top of the batch laid by th platform 9. This involves the location of the holding platform 24 in a position above the receiving level of the platform 9 and therefore this platform 9 is arranged to be raised as it is turned to displace the batch through 180.

This is achieved by connecting the hollow shaft I2 (which can slide axially on the shaft I3) to a plate 25 connected to posts 26 mounted to slide in fixed plates 21 carrying also the pivot I6 for the sector I5. The posts 26 are formed with racks "28 engaged by pinions 29 fast with bevel wheels 30; these wheels 99 mesh with a ring bevel gear 3| which is turned first in one direction and then in the other by a second box cam 32 fast with the cam I8 this cam 32 having a dwell part 32' and two operating parts 32 32 the cam 32 is engaged by a follower 33 on an arm 34 pivoted on a post 35 which together with the post I6 and :a further post 36 support the plates 21. The arm 34 has a driving bowl 3'! entering a groove 38 in the bevel 3 I. It will be clear that the continuous rotation of the cam assembly I 8, 32 will result not only in the turning of the support 9 but also in phase with that operation, the turning of the bevel pinions 30 and the pinions 29 and hence (through the racks 28 on the posts 26) the raising and lowering of the plate 25 and hence of the tubular shaft I2.

The timing is such that the lifting of the platform 9 takes place before its swinging movement as it passes over the holding support 24. As soon as the support has completed its 180 of movement, the cam 32 commences the lowering operation :so that the fingers of the support 9 pass through the grid of the holding support 24 and so leave or deposit the batch on the grid.

The foregoing operation of the platform 9 takes place while the batch is being built up on the platform 5 i. e. the Platform 9 is swung forward,

raised, lowered and swun back during the time taken to build up the stack on the platform 5 so that the platform 9 is in position to receive the next batch from its conveyor 2. During the time that the batch is being built up again on the platform 9 the batch already laid on the operative platform 5 is shifted transversely to be laid on the top of the batch last deposited on the holding platform by the platform 9. This shifting is achieved by moving the chains I intermitently for which purpose the chain Wheels 38 are mounted on shafts 39 of which one has a gear 48 (Figure 2) co-operating with a mutilated driving gear 4| constantly driven through worms and worm wheel gearing 42 by a shaft 43 itself geared to the shaft 22. To ensure the shiftin of the batch on the platform :3 pushers at can be pivotally carried by the chains 7 and be controlled by a cam track 4! to rock to push the batch from the platform.

The two batches are now supported one on top of the other on the holding platform 24 and in order to take away those collected stacks (distinguished from one another by the position of their folded edges) there is provided an endless band 14 having supporting arms 45, the band being continuously advanced so that one or other set of arms sweeps through the grid forming the holding platform 24 and carries away the stacks supported by it to for example the publication room.

In order to effect a positive control of the products as they pass across from the conveyor l or 2, control belts or wires 48 can be employed these passing over pulleys 69 supported by pivoted arms 50 free to swing to allow the control wires to yield from their normal setting.

The holding platform 2i can be adjusted as to height by slidably mounting that platform on posts 5|.
