'a' machine for automatically detaching single copies from a stock of vertical papers and piling them horizontally.
A further object of the invention is to provide a machine for entirely automatically delivering in an eflicient manner and with high speed single copies to an inserting machine, in regular intervals of time.
The invention also consists in a machine for automatically transforming a vertical pile of papers of any given quantity into a horizontal pile of a limited quantity and feeding the papers from the last successively in timed relation and equal intervals into conveyors leading to a machine for further treatment.
The form of the machine, which I have chosen to illustrate my invention, includes a plurality of conveyors, a rotating roller cooperating with the belts, an inclined board and rotating fingers, so that a copy supplied by the rotating roller and. stopped by the inclined board may be withdrawn by the fingers.
The various novel features of my invention will be apparent from the following description and drawings and will be particularly pointed out in the claims. f
In the drawings Fig. 1 is a side-elevation disclosing a form of execution of the invention,
Fig. 2 a side-view on the same scale, showing certain details of construction with parts broken away. I
Fig. 3 is an enlarged side-view of a portion of the machine; showing the inclined board in section. 1
Fig. 4 is a front-view of that board on the same scale.
Fig. 5 is a front-view of another portion of the machine, showing the propeller roller with gearing.
Fig. 6 is an end-view with some parts broken away of the preferred means for controlling the supply- Figs. 7 ande8 show the electric circuits, respectively for controlling the supplyand for control- .ling the height of the horizontal pile.
The machine illustrated includes upright frame members 1' and 2 and conveyors 3, 4 and 5, suitably supported between the frame members.
Referring to Fig. 2 of the drawings, the composition of the machine will be cleared. Between the frame members a roller 6 is so mounted, situated between the conveyors 3 and 4.. The conveyor 4 leads from the roller 6 to an inclined board 7, movably connected to the frame members by a support 8. Between the edge 9 of the board and the conveyor 4 a narrow passage is left, partially blocked by a resilienttonguepiece 10, adjustably connected tothe main board. Mounted adja'cently to the front-side of this board are rotating fingers 11 on shafts 12 carried by disks on a shaft 14 between the frame mem- 7o bers. The conveyor 5 is guided by suitable rollers and by the disks and is mounted partially adjacent and parallel to the conveyor 4, the upper part of this last conveyor being horizontal and constituting a. base for the horizontal papers which rest before the slot between the inclined board 7 and the conveyor 4.
Adjacent to the roller is a shaft 15, carrying striking arms 16, suitable means being provided to rotate the arms synchronously with the g roller 6. Suitable mechanism is provided for controlling automatically the supply of papers to the horizontal pile by stopping the feeding roller 6 when the number of copies on the horizontal belt surpasses a prefixed amount. Also suitable mechanism is provided for controlling automatically the progress of the belt 3, means being provided for stopping automatically the motion of this belt as soon as the verticalpile has acquired the desired inclination relative to the roller.
According to my invention, a bunch of papers A with their folded edge at the top and forward are deposited on the front-portion of the conveyor 3, resting against the roller 6 under an inclination, dependent from the quality of the papers. The friction with the revolving roller withdraws the foremost copy and lifts it, until it is bent towards the roller by the striking arms 16. The copy is withdrawn and forwarded to the horizontal pile in front by the roller 6, by friction with its surface. The bottommost copy of this last pile B is transported by friction with the conveyor 4 through the slot between the board 7 and the conveyor 4, against the resilient tonguepiece 10, so as to protrude enough from the pile to be gripped by the rotating fingers passing along the tongue-piece and withdrawing the bottom-copy.
Referring to Fig. 3 it will be seen that the 11 One feature of my invention is the transform ing of the main pile A deposited haphazardly on the first belt 3. It. is transformed into a light pile with stratified copies. The number of copies to rest on the second belt 4 may be controlled by the speed of the roller 6.
Referring to Fig. 2 of the drawings, the support is provided with a swiveling finger 1'7, the end of which rests on a predetermined distance above the horizontal part of the belt 4. This finger turns a shaft 18 and opens an electric circuit leading to a magnetic clutch in the gearing, driving the roller 6. The details of this construction will be explained afterwards.
Another feature of my invention is the automatic withdrawal of only one copy from the vertical pile by friction with the roller.
I prefer to control automatically the inclination of the foremost copies of that pile, so that they may stand under a useful angle on the conveyor 3 and are struck by the roller don the right place.
Referring to Fig. 2 the automatic device consists in a finger 19, activating an electromagnetic clutch in the driving gear of the conveyor 3. As soon as the foremost copy has reached with its under edge the desired position on the conveyor, a switch is broken and the progressive motion of the belt 3 is stopped.
81. Fig. 6 shows these pieces, connected with a,
- conduct 80 leading to brushes 23 resting upon conducting rings 24 fixed to a box 25, connected to the shaft 26 and containing an electromagnetic clutch 2'7 the box 25 being carried to the shaft and constituting the fixed part of the clutch. This shaft is supported between the frame members 1 and 2 and carries a gearing wheel 28, provided with'a friction disk 32 and fitted loosely on the shaft. At the end of the shaft a worm 29 is fixed, driving by means of,
the wormwheel 30 and pinionwheel 31 the propelling mechanism of the conveyor. When thecircuit is closed by the contacts 23, 24, the electromagnetic clutch is actuated and the gearing wheel 28 drives by adhesion the box of the clutch, which is keyed on the shaft. In this way the shaft 26 and the conveyor are: driven by the main mechanism. As soon as the stack 'of papers on the conveyor reaches the correct position, its under end touches the fingers 19 and lifts the contact-pieces 23 from the rings 24. The circuit is broken then .and the machinery of the conveyor is'stopped.
Referring to Figures 2 and 5, the mechanism controlling the height of the horizontal pile. of copies consists in a finger 1'7 connected to a shaft 18, oscillating in the frame. The shaft 39 driving the pinion wheel 40 on the shaft 41 of the roller 6. Fixed to this shaft is also a transmission wheel 41 driving the wheel 42, rigidly connected to the shaft 43 of the striking arms 16.
When the supply of single copies surmounts a certain number, the finger 1'7 (Fig. 2) is lifted,
the circuit broken, the clutch 33 is no longer activated and the friction disk 36 is free from the friction wheel 3'7, so that the shaft 38 and herewith the roller 6 is stopped. After decrease of the number of sheets to a desired level, the finger 17 swings downward and closes the switch and herewith the circuit to the clutch.
Referring to Fig. 3, the special part for statifying the horizontal pile in a stepped formation consists in the inclined board '7, connected to a support 8, mounted between the frame parts. The under edge of this board protrudes lightly inwards and lies above the horizontal conveyor 4 at a distance, large enough to allow the passage of one copy. Adjustably connected to this board is a feathering tongue-piece 10, which closes partially the slot between'the under edge 9 of the board and the conveyor 4. This tongue-piece is connected to the support by a pin 50, cooperating with a screw 51. A spring 52 detains the -slidable tongue-piece in its lowermost position until it is raised by turning the screw. The board is' provided with ports 53, through which pass the gripping elements of the withdrawing device. The whole support with its attached board can be lifted by means of the screw 54 and the spring 55.
Referring to Fig. 3, the bottommost copy is withdrawn by fingers 56 connected to holders 11, oscillating on shafts 12 supported in rotating disks 5'7.- The shafts are provided with cranks 58, fitted with rollers 59 running at the revolutions of the disks 57 over an unround disk 60 fixed adjustably to the machine. In this way by judicious choice of the form and location of the disk 60, the fingers 56 may be forced to strike the bottommost copy in the right position and withdraw it at the further revolution through-the narrow pasage under the feathering tongue-piece.
Referring to Fig. 2 it may be seen, that in this way the copy is caught between the conveyor 4 and the other conveyor 5, further led around the roller 61 along the roller 62, and between the rollers 63 and 64, from where it is taken for further treatment. The conveyor 4 is led along the horizontal part by the rollers 6'7 and 61, along the roller 62 and the rollers 64, 65 and 66.
The upper conveyor 5 is led around disks on the shaft 14, along the roller 61 and further by the rollers 62, 63, 68 and 69.
The conveyor 3, carrying the stack of papers, is led by rollers '70 and '71 and may run 'over rollers '72, '73 and '74. This conveyor is preferably made of elastic material and propelled by the gearing shown in Fig. 1 and partially described hereleading over the switch '81 to the brushes 23 and over rings 24 .to a coil 82. The current is fed from a battery 83 or other source.
The'system controlling the quantity of copies retarded before the inclined board consists in the finger 17 on the shaft 18, operating the circuit breaker 86 in the conduct 85, leading to the coil 87 and the battery or other source 88;
