Definitions

  • This invention relates to a sheet feeding apparatus and more particularly to a feeding apparatus adapted to feed cards to an apparatus for producing classification cards, and other cards, each having an image bearing frame of micro-film mounted in an aperture in the card and secured to an adhesive sheet carried by the card and extending over the aperture, whereby each card may advantageously contain a representative visible image or picture record of the data recorded or to be recorded, and each film frame may be conveniently filed, indexed, and classified as to subject matter.
  • One object is to provide an improved and simplified feeder of the friction separator roller type which is particularly, but not exclusively, adapted for feeding cards one after another from a supply stack thereof.
  • Another object is to provide ⁇ an improved feeder of the friction separator roller type wherein the hopper for supporting a supply stack of blanks, such as cards, in fanned-out relation is adjustable about an arc concentric with the axis of rotation of the separator roller so that the angle of ilow of the blanks toward the separator roller is always approximately tangent. to said separator roller in all positions of adjustment of said hopper, whereby accurate and continued feeding of blanks one after another from said stack may be achieved and feeding of only single blanks is assured.
  • Another object is to provideva Vfeeder of 'the above character having a feed roller and pressure rollers cooperating with and spaced axially of said feed roller, wherein said pressure rollers are, mounted in. a novel manner for adjustment independently as to pressure, and collectively as to location with respect to said feed ⁇ roller, so that uniform straight-line forward movement. of the blanks thereby is assured.
  • a still further object is'to provide novel means for releasably and drivably connecting an annular member, such as the' separator roller of a friction type feeder, to its operating shaft.
  • the apparatus constructed in accordance with the present invention and chosen for the purposes of illustration is particularlyV adapted for feeding cards of the type commonly employed in connection with statistical, tabulating and record card sorting systems and machines and wherein said cards are fed to an apparatus adapted to mount individual image bearing frames of the microlm therein. It is to be understood that the invention is not so limited and that the principles herein described are applicable to the feeding of a variety of different materials.
  • a supporting base and main driving mechanism is best shown in Figs. 1, 4, and 5.
  • the supporting base 12 rests on the machine foundation of suitable structure to hold and maintain said apparatus in the desired position.
  • the movable parts of the mechanisms for producing the card having a microlm mounted therein, together with the card feeder 14 and conveyor 15, are all preferably driven by the driving mechanism 13 which includes an electric motor 25.
  • the motor 25 is carried by the supporting base 12 beneath the platform 22, and is preferably mounted on said base in a suitable manner for pivotal up and down movement for a purpose to be presently described.
  • the motor 25 which is of the single phase type is supplied with electrical current from a suitable source and is controlled for starting and stopping purposes by a suitable manually operated switch which will be later explained in connection with the description of the electrical control circuit illustrated in Fig. 58, for the machine.
  • a pulley 26' Fixed on the armature shaft of the motor 25 is a pulley 26' which is preferably of the well-known variable diameter or speed type whereby the speed of operation of the machine may be regulated, as desired, through raisingxor lowering of said motor'. Passing around and driven by the pulley 26 is a belt 27 which also passes around and drives' a larger diameter pulley 28.
  • This pulley. 28 is loosely mounted on a short shaft 29 which extends longitudinally of the machine and is journalled in suitable bearings provided in the opposed walls of a gearbox 30 and in a bracket 31 which is located outwardly of and spaced from said gear box. The pulley 28 is thus driven continuously by the motor 25 when the latter is started.
  • Fig. 1 is a vertical sectional view of the card feeding apparatus, said view being taken substantially along the line 1 1 of Fig. 3; l FigLZ is an enlarged fragmentary vertical sectional view taken along' line V2- 2 of Fig. 3, with certain portions broken away' for purposes of clearer illustration;

  • tud 82 which is slidably engaged in and projects through an arcuate slot 83 which is formed in the bracketv81 concentric with the groove S and with the axis of rotation of the separator roll 63.
  • a nut 84 is vthreaded on the outwardly projecting end of the stud 82 and tightened against the bracket 81 to rmly hold the bracket 77 and the magazine side pans 72 and 73 in all angular positions of adjustment thereof.
  • the shelf 76 of the bracket 77 has suitably secured to the forward edge thereof a tongue 85 of resilient material, such as clock-spring steel for bridging the gap between the magazine side pans 72 and 73 and the separator roll 63 and for directing the foremost cards of the supply stack into position for feeding action of the separator rolll 63 thereon.
  • l Disposed below and cooperating with the separator roll ⁇ 63 in the feeding of the cards 5 successively from the supply stack is a retard pad or element 86 made of friction material, such as rubber, which serves to provide between it and said separator roll a feed throat for the passage of single cards only and to retard or hold back a second or succeeding-card against feeding movement simultaneously with a rst or preceding card.
  • the retard pad 86 projects through a suitable opening 87 in the tongue 85 and is normally spaced from the separator roll 63 a distance substantially equal to or slightly ⁇ less than the thickness of a card 5.
  • a lever 88 having a rearwardly projecting arm 89 and -a forwardly and upwardly projecting arm 90 which is bifurcated at the free end thereof.
  • the lever 88 is pivotally mounted on a stud 91 in a block 92 which is secured in a suitable manner to the lower surface of the shelf 76.
  • the retard pad 86 is cemented to a block 93 which is disposed within the free end of the armr90 of lever 83 and is pivotally mounted on a stud 94 in said arm, said stud being threaded into one side of the arm and utilized to also immovably clamp said block in its adjusted angular position to said arm.
  • a coil extension spring 95 Connected to the free end of the arm 89 of lever 88 is one end of a coil extension spring 95 the opposite end of which is connected at 96 to the shelf 76.
  • This spring 95 continuously tends to move the retard pad 86 downwardly away from the separator roller 63, said movement, however, being limited and regulated by an adjustable screw 97 threaded through a suitable opening in the arm 89 and engaging against the lower surface of the shelf 76.
  • the adjusting screw 97 is normally held against rotation by the expanding action of a coil compression spring 98 surrounding said screw and ⁇ disposed between the arm 89 and an Loperating head 99 on the screw. It will thus be apparent that an exceedingly accurate adjustment of the clearance between the retard pad 86 and the periphery of the separator roll 63 to permit only a single card to pass therebetween may be achieved by rotating the adjusting screw 97 in the proper direction by means of its operating head 99. When this adjustment has been made, the retard pad 8'6 wil'lbe maintained in its adjusted position by the 'contracting action of the spring 95 until such time lthat readjustment of .the clearance is required to compensate for the wearing of said retard pad -by the cards through continued feeding of the same thereover.
  • the separator roll 63 is intermittently rotated at timed intervalsV in a counter-clockwise direction-asA viewed in Fig. 8 to feed the cards 5 one after another in timed relation from the supply stack thereof.
  • the cam shaft gear 49 within thev gearbox 30 (Figs. 5 ⁇ and 6) has secured thereto orformed integrally therewith a spur gear 100 which meshes with and drives a spur gear 101.

  • the angle gear unit 103 is of well-known construction needing no detailed description herein and includes another shaft which is disposed at right angles to the shaft 102.
  • the gears 100 and 101 are of the same size and, hence, the shaft 105 of the angle gear unit 103 will also make one complete revolution for each cycle of operation of the machine.
  • the bracket 104 is bolted or otherwise suitably secured to the gear box 30 exteriorly thereof and projects into said gear ybox through a suitable opening therein to receive said angle gear unit.
  • crank disc 106 Keyed or otherwise suitably secured to the shaft 105 of the angle gear unit 103 is a crank disc 106 to which is pivotally connected by a stud 107 the lower end of a connecting rod 108.
  • the connecting rod 108 extends upwardly through a suitable clearance opening 109 in the plate 51 and is pivotally connected at its upper end by a stud 110 to the free end of a lever 111.
  • This lever 111 is engaged over and keyed to the hub of one member 112 of a conventional unidirectional wedging roller type of clutch 113.
  • the clutch member 112 is loosely mounted on the separator roll shaft 60, and the clutch 113 is of well-known construction having internal elements (not shown) one of which is keyed or otherwise suitably secured to said shaft and is connected with and rotated by the clutch member 112 upon rocking movement of said member in one direction only.
  • the shaft 60 and the separator roll 63 thereon will be rotated only on the down stroke of the lever 111 and will not be rotated on the up stroke of said lever, and as viewed in Fig. l0 which is a rear view of the card feeder 14, the active down stroke of the lever 111 and resulting rotation of the shaft 60 and separator roll 63 occurs in a clockwise direction.

  • the cards 5 are placed in the magazine 'facef wise with the adhesive sheet 7 at the top and with their longer dimension extending in the feeding direction and so that the transverse edge or shorter dimension nearest the adhesive sheet is leading.
  • the extent of rotation of the separator roll 63 upon each operation thereof as above described, is suicient to advance the uppermost card 5 from the supply stack a short distance and present its leading edge between a ,continuously driven lower feed roll 115 and cooperating Vupper pressure rollers 116 which complete the withdrawal of the card from the supply stack and further advance the same to the conveyor 15. It is to be noted that when the separator roll 63 has advanced the leading edge of a card 5 between the roll 115 and rollers 116, said separator roll, due to the described overrunning clutch drive therefor, will be rotated independently of said drive by the card as the same is pulled from beneath the separator roll by the advancing action of the feed roll 115 and pressure rollers -116 thereon.
