Definitions

  • the present invention relates to photocopy machines and more particularly to machines in which the copy paper is not pre-cut but delivered from a roll, to be cut to size determined by the size of the original to be copied.
  • the copy paper should be cut accurately to the same size as the original. It must not be smaller, lest information to be copied is cut off; and it should not be larger, both to avoid waste and for neatness of the copy received.
  • the speed of operation that is, the speed of the feed of the copy paper
  • cut-off knives and operating units therefor can be readily designed.
  • the speed of feed of the paper is substantially constant, then cut-off knives and operating units therefor can be readily designed.
  • the speed of feed of the paper is substantially constant, then cut-off knives and operating units therefor can be readily designed.
  • the speed of feed of the paper When, however, there is wide variation in the speed of feed of the paper, the operating requirements placed on the knife become severe. This problem particularly arises in machines in which light shines through an original which is passed over a predetermined exposure area in the machine, and the machine is designed to copy both from ordinary heavy grade paper, such as 20-pound bond paper, as well as from tracing cloth and onion skin.
  • the photocopy machine has a feed means for copy paper to feed the copy paper along a predetermined path.
  • a knife, or cut-off assembly is arranged in the path of the copy paper.
  • the knife is operated by an electric solenoid or other electromagnetic device,
  • the copy paper itself is fed by an electric mot-or.
  • the speed of the motor can be set manually over a wide range, or can be determined automatically.
  • the point of time at which the operating means, that is, the solenoid or other electromagnetic device, operates the knife, in relation to the position of the copy paper within the machine, is determined not only by the position of the copy paper, but further, by the speed of its feed.
  • This speed can be sensed, for example, by obtaining a representative value of voltage from the armature of the motor itself.
  • the cut-off mechanism or knife is caused to operate somewhat sooner than when the speed is low, so that the amount of paper passing the knife before the actual cutting occurs is approximately constant in any case, and independent of the speed of the paper transport.
  • Actual operation of the knife solenoid or motor can be initiated by sensing switches, positioned to cause switching action when the trailing edge of the original of the paper passes thereover. By staggering these switches along the feed of the original of the paper, earlier or delayed switching action can be obtained.
  • the speed signal obtained from the motor is then used to control which one of the staggered switches controls the cut-off knife.
  • a pair of such staggered switches can be used, and when the motor armature voltage exceeds a certain value, a relay switches over from the normally engaged feeding, or slow-speed switch, to the alternatively engaged trailing, or high-speed switch.
  • FIG, l is a schematic view illustrating the feed arrangement for both the original and the copy paper, and the placement of the switches, wherein conventional parts are illustrated in block, or schematic form;
  • FIG. 2 is a circuit diagram of the switching arrangement in the copy machine of the present invention.
  • FIG. 3 is a timing diagram illustrating the timing relationship of the various switches and elements of the apparatus.
  • copy paper 10 is reeled from a supply reel 11, passed over an idler roller 12, then between a pair of feed rollers 13, 13', which may be spring loaded to be pressed against each other as shown schematically, to a cut-off mechanism generally illustrated at 14.
  • the cut-off mechanism consists of a gate 15 and a movable knife 16, rotatably mounted to shear paper off extending through gate 15.
  • the cut-off mechanism 14 is operated by a solenoid, or other electromagnetic operating means 17 (FIG. 2) and not further illustrated in FIG. 1, since such cut-off mechanisms are well known.
  • the paper after passing the cut-off mechanism, is passed over a guide 18 to a feed belt 19 for delivery to an exposure area.
  • the belt 19 runs over an idler roller 22, and a drive roller 23 as well as beneath an idler roller 20.
  • Drive roller 13 is driven from a variable speed motor 25, as indicated by the dashed connection, with an electromagnetic feed roller clutch 26, well known in itself, being interposed in the drive connection.
  • the variable speed motor 25 further drives roller 23, as indicated by the dashed lines, to translate belt 19, in a manner well known in the art.
  • the original to be copied is fed over a platform guide or apron 30, which is suitably perforated to contain contacts of sensing switches which sense the leading and trailing edge of the original on guide 30. Suitable hold down means to assist in the sensing may be provided and are not shown for simplicity.
  • a leading edge sensing switch S2 Arranged beneath the guide 30 are three switches; a leading edge sensing switch S2, a leading cut-01f switch S4, and a trailing cut-off switch S5.
  • switch S4 is placed in circuit for slow speed operation
  • switch S5 is placed in circuit for high speed operation.
  • the motor, the cut-off knife, the feed roller clutch, and the switches are interconnected as shown in FIG. 2.
  • Power is supplied to the apparatus over incoming line 40, which may be 110 volts AC
  • a master ON-OFF switch S1 is in series with the line to provide main control and power the motor 25.
  • a conventional fuse F In series with switch S1 is the leading edge sensing switch S2, which when closed connects a full wave rectifier supplying power of approximately volts DC to either the clutch 26 or the solenoid of operating mechanism 17 for the knife assembly 14, as will be hereinafter more fully described.
  • Double throw single pole switches S4, S5 are connected in parallel, with their common connections brought to alternately engaged relay contacts S3; the common connection from relay contacts S3 are returned to the other pole of the DC sup ply.
  • the floor line position of the contacts as shown is the normal or rest position with switch S1 being open, or off.
  • the contacts S3 are controlled by relay coil 41, which in series with a limiting resistor 44 is connected across the armature and senses the armature voltage, as well known in the art. If the armature voltage exceeds a certain value, relay coil 41 will be sufficiently energized to pull the contact S3 from the solid line position over to the other contact.
  • the speed of the motor itself can be controlled either manually bysettingofa manual rheostat'42 or by an automatic speed control 43 which automatically determines the time exposure required to make a copy.
  • main ON-OFF switch S1 (FIG. 2) is closed to provide power to motor 25.
  • copy paper is not being furnished from roll 11, since S2 is open, and thus the feed roller 13 is not coupled to motor 25. Therefore the original is placed on guide 30 and slide forward to first engage switches 85, S4, causing them to change over from the solid line position to the not-drawn position (FIG. 2) so that DC circuit will be established through clutch 26, regardless of the position of switch 33 if the rectifier is energized.
  • Point zero in FIG. 3 is the rest position; point 1 shows the position when switch S1 is turned on energizing the motor 25.
  • Point 2 illustraes the closing of switch S and shortly thereafter point 2a the closing of switch S4.
  • the original As the original is manually advanced further, it will hit the leading edge switch S2 (point 3, FIG. 3) and S2 will close. Power will be applied to the clutch since switches S4, S5, are in their non-drawn position. Both copy paper as well as the original will feed toward roller 20 and over the belt, where they will be fed together in overlying position for exposure and making of the copy.
  • the motor will continue to turn, feeding the remainder of the copy paper and the original between roller 20 and belt 19 for exposure, and to another transport means (not shown) for completion of the copy process.
  • the copy paper feed and cut-olf mechanism will revert to rest, regardless of the opening or closing of switch S1.
  • switch S3 can then be provided with a greater number of contacts than two with a suitable operating mechanism therefor, causing selective engagement of these contacts in accordance with voltage derived from the armature of motor 25, to sense the speed and thus place the proper switch in the path of the original inserted with the cut-off mechanism.
  • the speed of motor 25 can be sensed by means other than the armature reaction voltages; for example, a tachometer can be used, or the speed of feed of the paper itself can be determined.
  • Switches, S2, S4, S5 are illustrated as mechanical contact switches, but they may be photo-electrically'or capacitatively operated, or may be switches taking other forms.
  • a photocopy machine for making copies from an original onto a light-sensitive copy paper which is being fed from a copy paper roll, a variable speed feed means for feeding said copy paper in a predetermined paper feed path, said feed means including a variable speed electric mot-or; cut-oil. means for said copy paper; electrical means controlling the operation of said cut-off means; and means sensing the speed of said motor, said speed sensing means controlling the application of potential to said electrical means thus controlling the operation of said cut-off means, whereby the actuation of said cut-off means will be dependent on speed of feed of said copy paper.
