Definitions

  • This invention relates to photocopying or duplicating apparatus and, more particularly, to the feeding and handling of sensitized paper in continuous sheet form for processing in such apparatus.
  • Photocopying employs light-sensitive materials which are exposed in contact with an original in order to obtain a print thereof.
  • thermo-printing use is made of heat-sensitive materials which, in contact with an original, are subjected to radiation rich in infrared to obtain a print of the original.
  • the diazotype machines are particularly advantageous. These generally employ a rotating glass cylinder containing an ultraviolet light source.
  • the sensitized sheet in contact with the original, is passed over the cylinder for exposure, after which the original is returned from the machine and the exposed sensitized sheet is conveyed further for either gaseous or moist development.
  • the roll stock of sensitized material is hand fed by the operator and cut to the required size by the snapping of a steel Wire at the time the original is about to be fully conveyed into the machine.
  • Such cutting can never be made accurately to the size of the original, thus leaving large margins of unused sensitized material to pass through the machine.
  • This represents not only a waste of the material itself, but also a waste of time caused, first by the operators judgment in cutting and, secondly, by the time required for the unused portion of the material to pass through the machine.
  • feeding from a storage roll into the duplicating apparatus is automatically effected by the presence of an original to be copied and such feed progresses until the original passes the reference point.
  • a further object of the invention is to provide means whereby the sensitized sheet material is automatically cut to any length corresponding to an original which may be inserted into the machine for copying.
  • the storage roll of the sensitized material located in a compartment may easily be inserted into the apparatus and the compartment automatically partially opened upon depletion of the roll so as to indicate the needfor refill,
  • FIG. 1 is a perspective view of the roll feeding attachment applied to a diazotype reproducing apparatus, various portions being broken away for illustration;
  • FIG. 2 is a schematic sectional view of the roll feeding and cutting apparatus
  • FIG. 3 is a partial sectional view of the roll storage compartment in tilted position
  • FIG. 4 is a perspective view of the drive and cutting assembly together with the circuit of the electrical sensing elements.
  • the automatic roll feeding device of the present invention may be applied to various types of duplicating or photocopyinng apparatus.
  • a conventional diazotype machine has been chosen as part of the assembly. Only pertinent portions of such a machine are illustrated since, except for the infeed of the original and sensitized material, the ensuing printing and developing functions have no bearing on the present invention.
  • the reproduction apparatus portion shown comprises the housing 6, the infeed rollers 7 and 8, the latter being driven by the chain 9.
  • the infeed channel for the original is provided by the guide plates 10 and 11 which converge toward the infeed rollers 7 and 8.
  • the latter in fact, carry the endless feed belts 12 which wrap around the printing cylinder within the machine, not shown here, and thus convey the original and the sensitized material.
  • the roll feed attachment in accordance with the invention, includes the roll compartment 14 which is tiltable over pivot 15, shown in FIGS. 2 and 3.
  • the spool 16 which carries the roll stock is supported in suitable bearings formed by a slotted block 17 attached to the inner Wall plate 18 of the roll compartment 14.
  • a pair of feed rollers 19 and 20, of which the latter is driven by means of a magnetic clutch and gear arrangement, is provided for conveying the sensitized material 22 into the reproduction machine, namely, between the bite of infeed roller 7 and 8.
  • the drive consists of the intermediate gear 23 which engages the gear 24 of the roller 20.
  • the coupling between these is controlled by an electric clutch 25, the operation of which will be described later.
  • the power drive may be taken from the duplicating machine in various ways. By Way of example, it is shown as comprising the chain 26, the sprocket 27 attached to the shaft of the infeed roller 8, idler sprocket 28, and drive sprockets 30 and 31, the latter driving the gear 23.
  • the sensitized material 22 is looped under a straightening rod 32 attached to the inner wall of the casing 33.
  • the purpose of the rod is to provide enough back curl to calender the rolled material 22 before it enters the driven components of the roll feeder. Passing under the rod 32, the material 22 is then inserted between the feed rollers 19 and 20 by rotating roller 19 by hand. This operation is performed by hand whenever a new roll of sensitized material is placed into the machine.
  • an electrically operated rotary knife 37 In the path of the sensitized material 22 is an electrically operated rotary knife 37, the stationary cutting edge thereof being part of the support 35.
  • the infeed channel for the original 29 is between guide plates 10 and 11 which converge toward the infeed rollers 7 and 8. At this point, the original 29 meets the sensitized material 22.
  • the feedin of the original is effected by rollers 39 and 40, the latter being power driven from the sprocket 30 over which the chain 26 is looped.
  • Extending into the infeed channel for the original 29 are resilient fingers 42 and 43 of electrical sensing elements in the form of switches 42' and 43', respectively.
  • a third switch 44 is placed further along the path of the original 29. It functions simply to activate a pilot light 45 for indicating the passage of the original 29 beyond this reference point, and the readiness of the apparatus to accept another original for processing.
  • the first step in the operation of the roll feed attachment is, of course, the loading of roll stock. This is placed in a special compartment 14 which is opened by tilting it over the pivot 15. The sensitized material 22 is then guided under the calender rod 32 as previously mentioned.
  • the pivot point of the compartment is eccentric with respect to the center of gravity so that it has a tendency to tilt open when there is only an empty spool therein.
  • the weight of the roll and/or the tension will maintain the compartment in closed position. This is a very convenient feature in that the automatic opening of the compartment gives notice that the supply roll has been nearly used up and insertion of a new roll is needed.
  • the leading edge of the sensitized material 22 is then fed between the feed-in rollers 19 and 20 by manually rotating the former until the material is engaged ap proximately ,2 to 3 inches and in position between the guide plate 34 and support 35.
  • a sheet of paper is inserted into the channel formed by the guide plates 11 and 10, the latter serving also as a feedboard, and is gripped by feed-in rollers 39 and 40. As it progresses toward the infeed rollers 7 and 8, its leading edge trips the finger 42 of the switch 42'.
  • this switch when actuated, it closes the clutch circuit, preparing it to be energized at alater time.
  • the clutch 25 will be energized and the sensitized material 22 will continue to be fed into the copying machine for processing.
  • the electrical source in FIG. 4 is represented schematically by terminals (T1 and T2) which may be attached at any convenient location to the duplicating machine power source, and by the rectifier 46.
  • a switch 50 is connected in the feeder circuit in order that the feeder device may be turned off completely, thereby allowing the operator to use the original feed system for the insertion of pre-cut sensitized material of a dilferent nature than the material already loaded in the feeder compartment.
  • Roll feeding attachment for copying apparatus utilizing sensitized continuous web, material which, in contact with an original to be copied, is fed between infeed rollers into said apparatus for processing, comprising a storage roll of sail sensitized material, feed means over which said material is constrained to pass, guide means for directing said material toward engagement between said infeed rollers, cutting means in the path of said sensitized material, inlet feed means for conveying an original including a support therefor converging toward said infeed rollers, a pair of electrical sensing elements activated by the leading edge of the original upon insertion and deactivated by the trailing edge thereof, one of said sensing elements controlling the actuation of the feed means of said sensitized material and the other of said sensing elements controlling the operation of said cutting means, said inlet feed means and infeed rollers being interconnected to advance the original and sensitized material at the same rate whereby the length of the sensitized material cut from said roll entering said apparatus is substantially the same as that of the original.
  • Roll feeding attachment for copying apparatus utilizing sensitized continuous web material which, in contact with an original to be copied, is fed between infeed rollers into said apparatus for processing, comprising a storage roll of said sensitized material, feed.
  • one of said sensing elements controlling 1 the actuation of said driven roller feeding said sensitized material, and the other of said elements controlling the actuation of said cutting means, whereby the length of the sensitized material cut from said roll entering said apparatus is substantially the same as that of the original.
  • one of said switching means controlling the energizing of said clutch and the other of said switching means controlling the operation of said cutting means, wherea by the length of the sensitized material cut from said 3 roll entering said apparatus is substantially the same as that of the original.
  • a roll feeding device for copying apparatus utilizing sensitized continuous web material which, in contact with an original to be copied, is fed between power operated infeed rollers into said apparatus for processing, a storage roll of said sensitized material, a drive roller and an idler roller between which said material is constrained to pass, an engageable power drive between said idler and drive rollers, an electrical clutch for said drive, a platform guide for directing said material toward engagement between said idler and drive rollers, a rotary knife in the path of said sensitized material, an inlet feed channel guiding the original to be copied toward said infeed rollers, a pair of electrical sensing elements actuated by the leading edge of the original upon insertion and released by the trailing edge thereof, the first of said sensing elements upon actuation establishing a circuit for energizing said knife and the second of said elements being actuated thereafter closing the circuit for said clutch, thereby energizing said power drive, said first sensing element upon being released by the trailing edge of said original opening the clutch circuit and simultaneously
