10 Claims. (Cl. 198-35) This invention relates to newspaper conveyors and has for its object the provision of means whereby the newspapers, while -on the conveyor may be stacked into batches.
The invention consists broadly of a newspaper conveyor system in which a succession of groups of overlapping papers Vare conveyed on a horizontal belt conveyor with spaces between the adjacent groups, wherein, as each group reaches a -given position, two barrier elements are moved laterally into the path of the papers, one before and the other behind such grou-p, and are then moved towards one another so as to cause the overlapping papers to slide together and form a stack.
In order that the invention may be the more clearly understood a system in accordance therewith will now ibe described reference being made to the accompanying drawings wherein:
Figure l is a somewhat diagrammatic side elevation of the system shown immediately prior to the commencement of a stacking operation;
Figure 2 is a similar view of the system shown after the rst step in the stacking operation;`
Figure 3 is a similar yview of the system shown at the end of said stacking operation;
Figure 4 is an end elevation of one of the parts vof the system;
Figure 5 is an electric circuit diagram illustrating elec- 4 trical c-ontrol circuits whereby the stacking operations are controlled automatically.
In the present arrangement, as soon as a quire reaches 50 a given positionviz the position of the leading quire in 'Figure l-a horizontal frame 3, which is located underneath the conveyor and which carries two upstanding forked blades 4 and 5 4(see also Figure 4) in spaced relation along the conveyor, is raised to the position of Figure 2 so -that lsaid two forked blades pass upwards between the belts of the conveyor, the arrangement being such that one of 'said blades, viz the blade 4 (hereinafter called the front blade) comes in front of the quire and the other, the blade 5 (herein-after called the rear blade) behind it. When the frame 3 is at its fully up position it stops and the front blade 4 4remains stationary. The rear lblade 5 is now moved horizontally forwards relative to said frame, until it is separated from the Ifront blade 4 only by the distance of one paper length as shown in Figure 3, and it will thus be seen that the overlapping papers of the quire are slid on top of each other Iuntil they form a vertical stack located between the two vertical blades 4 and 5.
When the rear blade 5 reaches its foremost limit, the frame 3 is lowered together with its blades and the rear blade 5 is returned rearwardly to its starting position, and all is ready for a repetition of the operation when r"ice the next quire reaches said -given position. It will thus be seen that the quires are formed into a series of spaced vertical stacks which are conveyed `along by the conveyor to a point of delivery.
For effecting the up and down movement of the frame 3, the same is mounted by means of a bracket 6 on the upper end of a vertical piston rod 7 whose lower end is secured to the piston of an air cylinder '8. :Each time a quire reaches the said given position of Figure 1, a light beam 9 is permitted to pass Ifrom a source of light 10 through the gap immediately behind said quire and to impinge upon a photoelectric device 11, and said photoelectric device thereupon (see Figure 5) completes a circuit through the winding RW of a relay, said circuit being traced from one mains terminal L1, Ithrough pole M1 of manually operated main switch, through said photoelectric device 11, through said relay winding RW, through a normally closed mechanically operated contact C1, and through the other pole M2 of the main switch to the other mains terminal L2.
iSaid relay therefore closes main contacts R1 and auxiliary contacts R2. Closure of said auxiliary contacts R2 establishes a maintaining circuit for said winding IRW as will be immediately clear from the drawing.
Closure of the main relay contacts R1 establishes an energising circuit Ifor a solenoid S1, and this operates a valve (not shown) which allows compressed air to enter the lower end -of the cylinder 8 by way of a conduit 12, and to exhaust from the upper end of said cylinder lby way of a conduit 13. The piston of said cyl- 'inder accordingly raises said frame 3 and blades 4 and 5 to the up position. It will be noted that according to Figure l, the light beam 9 strikes the photoelectric device 11 while the rear end of the quire is still vertically above rthe blade 5 but by the time the blade has moved upwards between the wires of the conveyor the quire 'has advanced sufficiently to clear said blade.
For effecting the horizontal movement of the rear blade 5 a second air cylinder 14 is provided, mounted horizontally in rigid relation on said frame, and the piston rod 15 of the piston -of said second cylinder is attached to said rear blade 5. When the piston rod 7 of the first air cylinder moves into its upper limit a projection 16 thereon mechanically closes a normally open contact C2 5' Iwhich thereby energises a second solenoid S2 (see Figure 5) which Voperates a valve not shown to allow'compressed air to enter said second air cylinder 14 by way of a conduit 15 at its rear end and to exhaust from a conduit 16 at its forward end. The piston yof ysaid air cylinder thereby moves said rear blade 5 forwards.
When said rear blade 5 reaches the forward limit of its movement a projection 17 on its piston rod 15 engages and opens the :aforesaid contact C1 which is connected in the circuit of the relay winding RW. The relay accordingly drops out and de-energises the first solenoid S1 which thereby operates the valve of the first air cylinder 8 to permit the compressed air to flow in through the conduit 13 and exhaust through the conduit 12, so that the frame 3 and its blades 4 and 5 are again lowered. This causes the aforesaid contact C2 to be opened which de-energises the solenoid S2, thereby operating the valve of the second air cylinder to permit compressed air to flow in through the conduit 16 and exhaust through the conduit 15, so -that the rear blade 5 is returned rearwardly to its normal position. This will of course reclose the Contact C1, but by now, as shown in Figure 3, the next quire will have cut off the light beam 9 from the photoelectric device 11, so the relay winding RW will not be re-energised until said next quire reaches said given position, whereupon the gap behind it will enable the photoelectric device 11 to be again activated and the whole cycle will be repeated for stacking said next quire- Obviously other means than compressed air, such for example as electric motors, could be employed for actuating the frame and the rear blade.
Furtheninstead of using a photoelectric device to initiate each cycle of operation, any other device, such for example as a sensitive limit switch responsive to the absence of paper, may be used.
In the arrangement above described the forming of the papers into a vertical stack is effected by keeping the front blade stationary and moving the rear blade horizontally forwards. In some cases it may be found better to move the front blade horizontally rearwards at the same time as the rear blade is moved horizontally forwards.
