Definitions

  • a cutter for cutting a sheet from a web e.g. a strip of a recording medium
  • a web e.g. a strip of a recording medium
  • an original sheet to be copied a switch for detecting the trailing end of a moving original sheet, and a plurality of signal switches adapted to be actuated in succession by a signal-transmitting element incident to advance of the original sheet along a defined path past the detecting switch.
  • the positions of the signal switches represent progressively increasing predetermined sheet lengths. Actuation of the detecting switch renders the signal switches effective to actuate the cutter, so that the first signal switch tobe actuated by the transmitting element after the trailing end of the original sheet passes the detecting switch produces a signal that actuates the cutter.
  • This invention relates to devices for automatically cutting a sheet from a strip, of material, and in a specific sense to devices for cutting and feeding a sheet of a recording medium (e.g. paper) to a copying machine or the like. More particularly, the invention relates to devices for cutting, from an advancing strip of a recording medium, a sheet of one of plural predetermined lengths selected automatically in accordance with the length of an original sheet to be copied.
  • a recording medium e.g. paper
  • the recording medium In the art of copying an original sheet on a photosensitive or other recording medium, it is common practice to provide the recording medium as a continuous strip in roll form and to deliver it in successive discrete sheets to the printing section of the copying machine (i.e. as successive original sheets to be copied are supplied to the machine) by means of a suitable cutting and feeding device. Ordinarily it is desired that the sheet of recording medium be cut to a length that approximates the length of the original sheet being copied.
  • This automatic operation generally involves detection of the trailing end of the original sheet (as the original advances into the machine) by means of a microswitch which produces a signal for actuating the cutter upon detection of the trailing end.
  • a microswitch which produces a signal for actuating the cutter upon detection of the trailing end.
  • the firstmentioned system affords the advantage that there are no variations in the length ofsheets of recording medium produced once the initial length setting is made, and hence successive copy sheets of the same size can positively be produced.
  • the second-mentioned system is superior to the first-mentioned system as an automatic sheet feed system, in that it obviates any presetting operation for selecting sheet length, it is not without disadvantages.
  • copy sheets produced from successive original sheets tend to vary in length from one another in practice because the originals are not necessarily equal in length but may vary considerably from one another. This causes difficulty when the produced copy sheets are bound in book form.
  • An object of the present invention is to provide an automatic sheet-feeding device (having utility for cutting and feeding sheets from a strip of recording medium to a copying machine) which combines the advantages of the aforementioned two systems of the prior art in a single device while obviating the disadvantages of the same.
  • a further object of the invention is to provide an automatic sheet-feeding device which does not require a length-setting or selecting operation prior to the feeding of an original sheet to the copying machine, yet which permits production of copy sheets of predetermined size even if there are variations in the size of originals.
  • an automatic sheet-feeding device (having particular utility in a copying machine) including a switch for detecting the trailing end of an original sheet during its movement in the machine, and a plurality of signal switches disposed along the path of movement of at least one signal transmitting element adapted to move in synchronism with the original and producing a signal to actuate a cutter for cutting an advancing strip of recording medium.
  • the plurality of signal switches are disposed in positions corresponding to a plurality of predetermined sizes of sheets to be produced.
  • the detecting switch, signal switches and cutter are mutually so arranged and adapted that that one of the signal switches which is first actuated by the signaltransmitting element following the detecting of the trailing end of the original sheet by the detecting switch produces a signal to operate the cutter.
  • This automatic sheet-feeding device of the invention requires no sheet size adjusting operation prior to the copying operation, yet enables production of copy sheets of uniform length in spite of variations in the length of originals.
  • the invention contemplates, in an automatic sheet-feeding device for cutting a sheet from an advancing strip of material as an original sheet advances along a defined path, the combination of means for cutting the strip in response to an actuating signal; means for producing a sequence of signals representative of progressively increasing predetermined sheet lengths in response to and in correspondence with advance of the original sheet along its path, the signal-producing means being connected to actuate the cutting means and being switchable from a condition in which the signals do not actuate the cutting means to a condition in which any signal of the sequence will actuate said cutting means; and means for detecting, and for switching the signal-producing means from the first-mentioned condition to the second-mentioned condition in response to, passage of the trailing end of the original sheet past a given point in the path, such that the cutting means is actuated by that signal of the sequence which is produced immediately subsequent to passage of the trailing end as stated.
  • the signal-producing means may include a plurality of signal-producing elements disposed in succession along a path of movement of an actuating or signal-transmitting element, and means for advancing the actuating element along the last-mentioned path into successive actuating engagement with the signalproducing elements, the signal-producing elements being disposed along the last-mentioned path in positions respectively corresponding to progressively increasing sheet lengths.
  • the original sheet inserted in the copying machine serves as the signal-transmitting element and the plurality of signal switches are disposed along the path of travel of the original sheet, each of such plurality of switches being spaced apart from the detecting switch for detecting the trailing end of the original sheet by a distance corresponding to one of a plurality of predetermined sheet lengths.
  • the signaltransmitting element is adapted to move with a rotary carrier, such signal-transmitting element moving in synchronism with the movement of the original sheet and such rotary carrier rotating at a rate of revolution which has a predetermined proportionate relation to the rate of movement of the original sheet.
  • the plurality of signal switches are disposed along the outer periphery of the rotary carrier.
  • FIG. 1 is a schematic view of a copying machine incorporating an automatic sheet-feeding device which embodies the present invention in a particular form; and I FIG. 2 is a schematic view of another embodiment of this invention.
  • a copying machine 2 is supported on'a bed 1 and an automatic sheet-feeding device 3 is disposed on the left side of the bed.
  • the copying machine 2 is of a well-known construction which will be briefly described, as illustrative of one type of apparatus with which the devices of the present invention are adapted to be used.
  • An original sheet 18 inserted through an insertion port of the machine and a photosensitive copy sheet (i.e. a sheet of a photosensitive recording medium) supplied from the sheet-feeding device 3 are supported one on the other in overlapped relation between a printing cylinder 4 and a conveyor belt 5 and moved. While the overlapped sheets are moved, an image of the original is printed on the photosensitive sheet by means of a printing lamp 6.
  • a photosensitive copy sheet i.e. a sheet of a photosensitive recording medium
  • the overlapped sheets are separated into the original sheet 18 and exposed photosensitive sheet by suction-type separation means 7 and 8, the original sheet 18 being delivered to an original tray 9A and the exposed photosensitive sheet being transmitted to developing means 10 which develops the photosensitive sheet and discharges the same through discharge rollers into a copy sheet tray 9B.
  • the automatic sheet feed device 3 comprises a continuous web or strip of photosensitive paper in the form of a roll 11, feed rollers 12, a rotary cutter 13 and means defining a sheet-conveying path suitably arranged in the device.
  • a microswitch 14 for detecting the trailing end of an introduced original sheet is disposed near the original sheet insertion port in the path of advance of the original sheet, and a second microswitch 15 for detecting the leading end of the original sheet is disposed beyond the switch 14 in the path of advance of that sheet.
  • a plurality of microswitches 16A, 16B and 16C for producing a signal to the rotary cutter 13 to actuate the same are disposed along a portion of a joint path of travel of the overlapped original and photosensitive sheet. Switches 16A, 16B and 16C are disposed at successively greater predetermined distances from the location of the detecting switch 14; these distances respectively correspond to successively increasing predetermined sheet lengths.
  • switches l4, 15, 16A, 16B and 16C as well as the feed rollers 12 and cutter 13 are interconnected electrically in appropriate manner to provide their desired interacting functions (hereinafter described) through appropriate circuitry represented in FIG. 1 by electrically controlling means 17.
  • electrically controlling means 17 For the sake of simplicity, the details of the control circuitry 17 are not shown, but the arrangement and operation of that circuitry will be readily apparent to those skilled in the art from the following description.
  • Actuation of switch 14 by passage of that trailing end functions to switch the signal-producing array of switches 16A, B and C to an effective condition such that the next signal switch (16A, B or C) engaged by the leading edge of a sheet 18, i.e. after the trailing edge passes switch 14, actuates the cutter 13 to cut the strip 1 1
  • the operation of the automatic copy sheet device constructed as aforementioned will now be described. If the original sheet 18 is inserted through the insertion port, then the leading end of original sheet 18 is detected by the microswitch 15 which produces a signal for operating the feed rollers 12 through the control means 17. Rotation of the feed rollers 12 causes the strip 11 of photosensitive paper to be moved forwardly.
  • the leading end of the original sheet is successively brought into contact with the microswitches 16A, 16B and 16C in the indicated order.
  • the microswitches 16A, 16B and 16C do not render the cutter l3 operative even if the leading end of the original sheet is brought into contact with any one of them, unless the trailing end of original sheet 18 has passed by the microswitch 14. It is not till the trailing end of the original sheet is released from engagement with the microswitch 14 that the cutter 13 is rendered operative, i.e. by that one of the microswitches 16A, 16B and 16C which is first brought into contact with the leading end of the original sheet following the release of the trailing end of the original sheet from engagement with the microswitch 14.
  • the photosensitive strip 1 1' is cut when the cutter 13 is rendered operative in this manner.
  • the distance between the microswitch 16B and microswitch 14 is determined so that it corresponds to the length of a sheet of the desired given size.
  • the cutter 13 is not actuated when the trailing end of an original sheet of the given size is released from engagement with the microswitch 14 but actuated when the leading end of the original sheet actuates the microswitch 16B following the release of the trailing end thereof from engagement with the microswitch 14.
  • the microswitch 14 is preferably disposed in a position which is displaced a small distance rearwardly of the position corresponding to the given size so as to ensure that the microswitch 14 is first actuated by the trailing end of the original sheet and then the microswitch 16B is actuated by the leading end thereof irrespective of variations in the length of successive original sheets.
  • the strip 11' of photosensitive paper is accurately cut into sheets of the desired given size by the cutter l3 actuated by the microswitch 168 at all times.
  • the microswitch 14 does not itself actuate the cutter 13 but instead performs the function of selecting a suitable switch from among the microswitches 16A, 16B and 16C for rendering the cutter 13 operati e.
  • the feed device is constructed such that the positions of microswitches 16A, 16B and 16C are adjustable, so that the microswitches can be operated to produce a sheet of any size as desired.
  • FIG. 2 shows an embodiment of the invention provided with signal delay means 19 instead of disposing the set of microswitches 16A, 16B and 16C for detecting the leading end of an original sheet, as shown in FIG. 1.
  • the signal delay means 19 comprises a rotary carriage 20 which rotates in the direction of the arrow at all times at a rate of revolution which is at a definite ratio with respect to the rate of movement of the sheet.
  • the rotary carrier 20 is adapted to carry signal-transmitting elements 21 which are magnetically attracted to the outer periphery of the rotary carrier. When no signal is applied to a solenoid 25, the signal-transmitting elements 21 are prevented by a first locking pawl22 from moving together with the rotary carrier 20 as a unit.
  • the numeral 23 designates a second locking pawl which is connected to the first locking pawl 22 through a seesaw lever 24, so that the two pawls 22 and 23 alternately move up and down.
  • a signal is supplied to the solenoid 25, it is energized and moves the first pawl 22 upwardly.
  • the movement of the first pawl 22 is transmitted through the seesaw lever 24 to the second pawl 23 which is moved downwardly.
  • the numerals 26A, 26B and 26C refer to switches which correspond to the microswitches 16A, 16B and 16C for detecting the leading end of an original sheet as shown in FIG. 1.
  • the switches 26A, 26B and 26C are disposed in the vicinity of the outer periphery of rotary carrier 20 and adapted to be actuated by the signal-transmitting element 21.
  • the feed rollers 12 are operated to feed the strip 11' of photosensitive paper.
  • the microswitch 15 produces a signal which is transmitted through the electrically controlling means 17 to the solenoid 25 to energize the same.
  • Energization of solenoid 25 moves the first pawl 22 upwardly and simultaneously moves the second pawl 23 downwardly through the seesaw lever 24. Accordingly, the first signal-transmitting element 21 which has been locked by the first pawl 22 is unlocked and allowed to move together with the rotary carrier 20, and the other signal-transmitting elements 21 are locked by the second pawl 23.
  • the first signal-transmitting element 21 moving with the rotary carrier 20 progressively depresses actuators for switches 26A, 26B and 26C. Although the signal-transmitting element 21 successively depresses the actuators for all the microswitches 26A, 26B and 26C, the microswitch which actuates the cutter 13 is selected by the microswitch 14 for detecting the trailing end of an original sheet 18, i.e. in the same manner as in the embodiment shown in FIG. 1.
  • the switches 26A, 26B and 26C may be constructed so as to permit adjustment of their positions as is the case with the microswitches of the first embodiment shown in FIG. 1.
  • the device according to this invention permits production of copy sheets of a predetermined size in accord with standards even when originals vary in length from the standards by inserting the original in the copying machine without any preoperation.
  • Incorporation of the present device in the copying machine offers the advantage of permitting automation of a copying operation and various operations following the copying operation because it is possible to provide photosensitive sheets of constant lengths at all times.
  • reference to signal-transmitting elements includes not only the elements 21 of the embodiment shown in FIG. 2 but also a member, such as the original sheet 18 of the embodiment shown in FIG. 1, which actuates the microswitch 16A, 168 or 16C after a predetermined time has elapsed or after it has moved a predetermined distance following its actuation of the microswitch l5.
