Filed Mama, 1961, Ser. No.95,715 4 Claims. (Cl. 83209) This .invention relates to a paper feeding and cutting machine, and more particularly to a machine for selecting and supplying paper, such as sensitive paper, of desired Width from available supplies of different widths, and cutting the selected paper to the desired length to accord with a master sheet with which the same is to be used.

Reproduction machines for rapid production of copies from negatives or master sheets are in common use. No satisfactory equipment is available for supplying the copy paper of a width and length .to conform to the master sheet with a minimum .of Waste and as called for by the size of the master sheet.

The feeding of the master and sensitive sheets to the copying machine is currently performed as a manual operation in which the original is picked up and a selection is made by the operator of a copy sheet of the desired size from a stock of copy material cut to size. The original and copy sheet are aligned and the two sheets are fed together into the machine. In most instances, these operations cannot be performed with suflicient rapidity to utilize the capacity of the reproduction equipment and there is no accommodation to still different sizes of master sheets.

While some efforts have been made to feed a continuous strip of copy paper into the machine accompanied by the master sheet, this does not permit of .accommodating the print to the size of the master sheet, results in excessive waste of the sensitized material, and requires excessive cutting subsequent to severing from the strip to trim the .copy sheet to size.

It is the principal object of the present invention to provide a machine for delivering an original and copy sheet of correct size in alignment to a machine for producing copies in which a measurement is made of the width of the master sheet, a selection is made of copy sheet material of suitable width, the master sheet and copy strip are aligned, the master sheet and selected copy strip are advanced, a proper length of copy sheet is transversely severed from the selected copy strip, and the master sheet and transversely severed copy sheet are advanced together to the reproduction machine.

It is a further object of the present invention to provide a paper feeding and cutting machine having a plurality of rolls of printing or copy paper of differing widths therein, together with simple but effective structure for measuring the width of the master or original from which a copy is to be made, and selecting and causing the advanoe of material of appropriate width to conform to the width of the master sheet.

It is a further object of the present invention to provide a paper feeding and cutting machine having a plurality of rolls of printing orcopy paper of differing widths therein, together with structure for selecting a copy sheet of proper width and aligning the leading edge of the original and the leading edge of the selected copy sheet.

it is a further object of the present invention to provide a paper feeding and cutting machine having provisions for simultaneously advancing the original or master sheet and a-strip of copy sheet with the leading edges of the original and the copy sheet aligned, and severing the copy sheet at a length determined by the length of the original or master sheet.

It is a further object of the present invention to provide a paper feeding and cutting machine having a plu- Platenteol May .11, 1955 ICC rality-of sources of paper of different widths and simple but effective transverse paper cutting mechanism acting on the selected strip of papen It isa'further object of the present invention to provide a paper feeding and cutting machine in which the measuring, selecting, edge alignment, transverse severing, and feeding are carried out as a continuous and automatic operation.

The washers 27 and nuts 28 when in position retain the plates 24 in assembled relation.

At the inner margin of the feed table 17 and beneath the. top wall section 20, a front pair of master sheet feed rollers 34B and 31 is provided in engagement. 'Fhe rollers 30 and 31 are carried respectively by shafts 32 and 33 journalled in the plates 24, one of the feed rollers, such as the roller 30, being driven by a gear motor 35 connected to the shaft 32 through an overriding clutch 36 and controlled as hereinafter pointed out.

Rearwa-rdly of the rollers 30 and 31 and beneath the e? top wall section 20, an intermediate pair of master sheet feed rollers 37 and 38 is provided carried by shafts 39 and 40 journalled in the end plates 24, one of the rollers such as the roller 37 being driven by a gear motor 41 connected to the shaft 39 through an overriding clutch 42 and controlled as hereinafter pointed out.

Rearwardly of the rollers 37 and 38 endless delivery conveyor belts 45 and 46 are provided with feed portions in closely spaced relation. The upper belt 45 is carried on a conveyor belt drive roll 47 which is mounted on a shaft 48. The shaft 48 extends through brackets 49 carried by each of the frame plates 24, and is driven by a gear motor 43 through an overriding clutch 44. The rear end of the upper belt 45 is supported on a conveyor belt roll 50 mounted on a shaft 51 which is journalled at its ends in the brackets 49. A belt tensioning roller 52 can be provided intermediate the roll 47 and the roll 50.

The motors 35, 41 and 43, are electric motors and are energized from any suitable source of electric energy.

The lower conveyor belt 46 is carried on a front belt support roll 54, is mounted on a shaft 55, which is journalled in the end frame plates 24 and on a rear support roll 56 which is carried on a shaft 53 and is journalled at its ends in the brackets 49. A tensioning roller 57 can be provided internally in the lower conveyor belt 46 for controlling the tensioning thereof.

In the space between the front rollers 30 and 31 and the intermediate rollers 37 and 38, a transversely disposed supporting gage plate 58 is provided and beyond the rollers 37 and 38 a guide plate 59 is provided with its face disposed tangential to the meeting location of the upper and lower conveyor belts 45 and 46.

A detector mounting channel bar 60 is provided having a dimensional scale 61 along the front margin thereof. The bar 60 has end pins 62 extending downwardly therefrom and slidable in the frame plates 24, springs 63 surrounding the pins 62 and abutting against the bar 60 and the frame plates 24 providing a resilient support for the bar 60.

A plurality of detector holders is provided, the detector holder 64 aiding in master sheet length measurement, and the detector holders 65 being provided one for each width control desired.

The gage plate 58 preferably has a plurality of detector pockets 66 provided therein at predetermined transversely spaced intervals, and preferably at each inch transversely of the gage plate 58 and aligned with the markings on the scale 61. Each of the detector holders 64 and 65 carries a detector element which may be a microswitch 67, 67a, 67b, 67c, 67d, actuated by a switch arm 68. Each arm 68 normally extends into a pocket 66 unless moved outwardly therefrom by the master sheet coming into contact therewith, as hereinafter explained.

In the space below the gage plate 58 an anvil mounting bar 70 is provided secured at its ends to the plate 58 and carries an anvil plate 71, preferably of nylon, on the lower face thereof for aiding in transverse strip severing, as hereinafter explained.

Upper and lower stock guide plates 69 and 69a are provided, the upper guide plate 69 extending downwardly from the master sheet guide plate 59 to the anvil plate 71. The space between the stock guide plates 69 and 69a faces to the entrance to the conveyor belts 45 and 46.

In accordance with the number of rolls of copying paper which it is desired to mount or store in the machine for availability for selection and supporting of stock,

cradle rolls 72 are provided for supporting rolls of sen-- sitized or copy paper for feeding. The cradle rolls 72 are rotatably supported at their ends in the end frame plates 24, access openings 73 being provided in the frame plates 24 for the insertion of a roll of sensitized or copy paper.

As shown, and merely by way of illustration, four sets of cradle rolls 72 are provided. Each set of cradle rolls 4 72 preferably has a stock holder bar 74 associated therewith with clamps 75 adjustably mounted thereon at one or both ends and each having an upwardly extending arm 76 for end abutment against the paper roll to limit the sidewise displacement thereof.

Each set of cradle rolls 72 also has contiguous thereto antidrag rollers 77 about which the paper from the paper supply rolls is directed. The rollers 77 are rotatably supported in the end frame plates 24.

Each set of cradle rolls 72 has a pair of contacting stock feed rollers 78 and 79 associated therewith. The rollers 78 and 79 are respectively carried on shafts 80 and 81 journalled in the end frame plates 24, and the shafts 80 and 81 are moved in unison by gears 80a and 81a secured thereto. One of the shafts, such as the shaft 81, can have a hand wheel 81b thereon for manual turning to initially adjust the paper to be advanced thereby.

One of the stock feed rollers 78 and 79, such as the roller 78, is driven in any desired manner, such as by electrically driven gear motors 82, 82a, 82b, 820, each connected thereto through an overrding clutch 83.

A spring clip 84 can be provided engaging each of the shafts 80, the spring clips 84 each being carried on pins 85 on the end frame plate 24, each acting as a brake and accommodating various thicknesses of stock.

Sensitized paper feed passageways are provided from each set of stock feed rollers 78 and 79 to the anvil plate 71, formed by guide plates 86 in converging relation toward the anvil plate 71. The guide plates 86 are provided with guiding ribs 87 and have disposed therebetween advancing rolls 88 carried on shafts 89 journaled in the end frame plates 24. The advancing rolls 88 preferably have friction facings 8811 over portions of their circumferences so that upon rotation of any of the rolls 88, the sheet material is prevented brom bunching or collecting in the passageways between the guide plates 86.

The shafts 89 are connected to and selectively driven by rotary solenoids 90, 90a, 90b and 900.

It will be noted that the centers of the feed rolls 78 and 79, as seen from the ends, are arranged on a common center so as to have the meeting portions of the rolls 78 and 79 all at the same distance from a predetermined line on the anvil plate 71 to insure uniformity of linear paper feed from each roll of sensitized or copy paper.

The paper cut-off mechanism, shown in detail in FIGS. 4, 5 and 6, preferably includes, for coaction with the anvil plate 71, previously referral to, a cutter bar 91 having a steel rule 92 secured thereto by a plurality of studs 93 extending through slots 94 in the rule 92.

The cutter bar 91 is pivotally connected by guide links 95 to a supporting bar 96 which is supported by the end frame plates 24. In order to move the cutter bar 91 toward the anvil plate 71, an actuating link 97 is provided.

The actuating link 97 is connected to an eccentric pin 98 which is adjustably mounted by studs 99 extending through elongated slots 100 in a pin carrying head 101. The studs 99 extend into a driving block 102 which is secured to a shaft 103, the shaft 103 in turn being connected through a single revolution clutch 104 controlled by a solenoid 105 to a flywheel 106. The flywheel 106 has a groove 107 on the periphery thereof for engagement by a driving belt 108 which is in engagement with a driving pulley 109 on a shaft 110 of a continuously operating electric motor 111. The motor 111 is supported by the end frame plate 24 at the right.

The structure for selectively controlling the paper feed and paper cutoff will now be described.

The microswitch 67 in the detector holder 64( see FIG. 7) has a conductor 115 extending from a suitable source of electrical energy to a movable contact 116, which contact 116 is controlled by the arm 68 of the microswitch 67. The arm 68 is actuated and moved to microswitch actuating position by the presence of the master sheet in engagement therewith. The microswitch 67 has a pair of fixed contacts 117 and 118, the contact 117 being connected by a conductor 119 through a single impulse pass device 120, commercially available .under the name Pulse-Pak, and through an adjustable time delay .relay 121 toone terminal of the winding of the clutch operating solenoid 105. The other terminal of the Winding of the solenoid 105 can be connected by a suitable conductor 122 toground.

The detector holders 765 are each provided with microswitches 67a to 67d, respectively, the number being dependent upon the number of rolls of sensitized paper carried on the respective groups of cradle rolls 72.

The microswitch 67a has a pair of fixed spaced contacts 123 and 124, and has a movable contact 125 which is connected by a conductor 126 to any suitable source of electrical energy. The movable contact 125 of the microswitch 67a is controlled by its actuating arm 68, Which is in turn actuated by the presence of the master sheet in engagement with its arm 68. The contact 124 of the microswitch 67a is connected by a conductor 127 to the movable contact 128 of the microswitch 67b which ,microswitch 67b is positioned by its arnr68.

It will be noted that unless and until the microswitch 67a has its movable contact 125 moved into engagement with the fixed contact 124, that no energizing circuit is set up therethrough.

The microswitch 67.5 has a pair of fixed spaced contacts 129 and 138 for selective engagement by the movable contact 128. The contact 129 is connected by a conductor 131 to the rotary solenoid 90 for rotating the shaft 89 and the roller 88-thereon and by a conductor 132 to the motor 82 for actuating the rolls 78 and 79. The rotary solenoid 90 and the motor 82 are connected by a conductor 133 to ground.

The contact 138 of the microswitch 67b is connected.

by a conductor 134 to the movable contact 135 of the microswitch 670 which contact 135 is positioned by its arm 68. The microswitch 670 has a pair of fixed spaced contacts 136 and 137 for selective engagement by the movable contact 135.

The contact 136 is connected by a conductor 138 to the next rotary solenoid 90a for rotating the next shaft 89 and roller 88 thereon and by a conductor 139 to the next rotor 82a for actuating the next set of rolls 78 and 79. The rotary solenoid 90a and the motor 82a are connected as before by the conductor 133 to ground.

The contact 137 of the microswitch 67c is connected by a conductor 140 to the movable contact 141 of the microswitch 67d which contact 141 is positioned by its arm 68. The microswitch 67d has a pair of fixed spaced contacts 142 and 143 for selective engagement by the movable contact 141. The contact 142 is connected by a conductor 144 to the next rotary solenoid 98b for rotating the next shaft 89 and the roller 88 thereon and by a conductor 145 to the next motor 82b for actuating the next set of rolls 78 and 79. The rotary solenoid 98b and the motor 82b are connected as before by the conductor 133 to ground.

The contact 143 of the microswitch 67d is connected by a conductor 146 through branch 147 to the next rotary solenoid 90c for rotating the next shaft 89 and the roller 88 thereon, and through branch 148 to the next motor 82c for actuating the next set of rolls 78 and 79. The rotary solenoid 98c and the motor 820 are connected as before by the conductor 133 to ground.

The mode of operation will now be pointed out.

The motor 111 is energized to rotate the flywheel 186 and the motors 35 and 41 are also energized to drive the feed rollers 31) and 31 and the feed rollers 37 and 38.

The motor 43 is energized to operate the drive rolls 47 and 54 and to operate the upper and lower conveyor belts 45 and 46. p

The machine is now ready for use. If now a master sheet is advanced rearwardly over the platform or feed table 17 with its margin along the inner end wall 18 at the left as a gage, the master sheet strikes and moves the 8 actuator arm 68 of the microswitch67 to move the movable contact 116 to the unenergized contact 118 so that the cutter bar 91 and rule '92 are in their retracted positions preliminary to but ready for movement for subsequent cutting, as hereinafter explained.

One or more of the actuating arms 68 of the microswitches 67a, 67b, 67c, and.67d, will be moved, dependent upon the width of the .master sheet to select the proper roll stock widthfor sensitized paper delivery.

Assume a relatively narrow Width of master sheet but sufficient to move the arm '68 of the microswitch 67a, then .the minimum widthof roll stock will be made available in the manner to be explained.

The movement. by the arm 68 of the movable contact 125 of the microswitch 67a to engage the contact 124 will set up an energizing circuit through the conductor 127, the contact 129, and the conductors '131 and 132 to the solenoid 98 and the motor 82.

Upon energization of the motor 82 the shaft rotated thereby is effective to rotate the feed roller '78 thereon, the feed roller 79 being driven in unison by the gears 80a and 81a. At the same time, energization of the rotary solenoid is effective to rotate the shaft 89 and the advancing roll 88 thereon. Paper from the roll supported on the cradle rolls 72 and threaded around the antidrag roller 77, is advanced by the feed rollers 78 and 79 and in the passageway between a pair of guide plates 86 past the anvil plate 71' to meet the leading edge of the master sheet at the entrance to the .conveyor belts 45 and 46. The master sheet and paper from the sensitized roll advance together between the conveyor belts 45 and 46. This feeding continues until the trailing edge of the mas ter sheet permits the actuating arm 68 of the microswitch 67 to be returned so that the movable contact 116 of the microswitch 67 will engage with the fixed Contact 117' and set up a paper cutoff energizing circuit through the conductor 119, the impulse control unit 120, the time delay relay 121, and the solenoid to actuate the clutch 104 to connect the shaft 183 for effecting movement of the link 97 to move the cutter bar 91 and the rule 92 toward the anvil plate 71 to sever the roll stock as determined by the delayed timed operation of the cutter bar 91.

The severed sensitized sheet is fed with the master sheet by the conveyor belts 45 and 46 to the machine at which the exposure or developing action is accomplished.

If wider roll stock is called for by movement of the actuating arm 68 of the microswitch 67b, an energizing circuit is set up through the contact 130, the conductor 134, the movable contact 135, and the contact 136, and conductors 138 and 139, to energize the rotary solenoid 98a and the motor 82a to feed stock from a roll of greater Width. It will be noted that if the rotary solenoid 98a and the motor 82a are energized, the rotary solenoid 90 and the motor 82 are not energized by reason of the selection by the movable contact 128.

If still wider roll stock is called for by movement of the actuating arm 68 of the microswitch 67c or the microswitch '67d, energizing circuits will be set up similar to those previously explained for operating the feed rollers 78 and 79 to supply the proper width of sensitized paper.

The leading edge of the paper which has been severed is available for advance if and when called for by the master sheet whose Width is related to the stock required. In the event that the same or a different width is called for by the next master sheet, the appropriate gear motor 82 to 82c and rotary solenoid 99 to 980 for feed are actuated to feed the sensitized sheet of selected width and for longitudinal severing as determined by the distance between the leading and trailing edge of the master sheet and the timing as set at the time delay relay 121.
