Definitions

  • ABSTRACT An apparatus for accepting a number of record cards [111' 3,823,936 1451 July 16, 1974 and selectively feeding the cards, one at a time, to another station for operations such a reading and writing.
  • an operator will insert the cards through an opening in the housing enclosing the apparatus-Beyond the opening in the housing is an expandable pressure throat made up of angularly extending wings integral with a rotatable card lifter and a rotatable pressure plate.
  • the stack With the stack of cards fully inserted and against a knife blade and guide, the stack is maintained intact by 1) a pressure roller connected to the pressure plate and forming part of the pressure throat, 2) card lifter rollers connected to the card lifter and forming another part of the pressure throat, and 3) the pressure plate itself forcing the stack against a baseplate carrying the card lifter.
  • a feed roller In the normal position a feed roller is spaced from the pressure roller, and is located on the same plane with the pressure and lifter rollers.
  • the pressure plate is spring biased against the stack such that the stack is maintained intact in the vicinity of an exit throat and the entry throat.
  • the feed roller is a continually rotating roller which is brought into contact with an outer card on the stack each time the card lifter is rotated. When this occurs, the outer card is ejected through the exit throat made up of an opening between the knife blade and a throat piece connected to the baseplate. Thereafter, the lifter is rotated back to its normal position and the cards are brought out of contact with the feed roller.
  • This invention relates to media handling apparatuses in general. More specifically, this invention deals with an apparatus for receiving a stack of record cards and feeding the cards, one at a time, to other stations for such operations as reading and writing.
  • a cammed pulley in conjunction with a belt is used for driving the bottom card from a stack.
  • a friction belt is brought into contact with the bottom card through an opening in a baseplate for driving the bottom card between two rollers beyond the throat.
  • the last patent referred to above discloses essentially the same material as the first mentioned IBM TDB.
  • weights have been used. These weights have been placed on top of the card stack.
  • the apparatus is generally made up of a rotatable pressure plate and a rotatable card lifter having angularly extending wings on one end thereof.
  • the angularly extending wings of the pressure plate and card lifter form an entry throat which is expandable for receiving a stack of record cards.
  • Within the entry throat are' l) a pressure roller rotatable about the same axis as the pressure plate, and 2) card lifter rollers normally in contact with the pressure roller and having their axial shafts journaled in the card lifter.
  • the pressure plate and pressure roller are displaced against a spring. Further insertion of the cards will be between the pressure plate and a baseplate which carries the card lifter.
  • the terminus of the apparatus as far as insertion of the stack of cards is concerned is a knife blade and guide against which an end of the stack of cards is aligned.
  • the spring causes forces to be applied to the cards both at the plane of the pressure and lifter rollers, andat the far extremity of the pressure and baseplates adjacent the knife blade.
  • an exit throat made up of a throat piece secured to the baseplate and spaced from the knife blade a distance equal to the thickness of one card.
  • a continually rotating motor driven feed roller normally spaced out of contact with the cards.
  • the end of the card lifter opposite the integral wing is rotated, allowing the pressure roller to bring the stack of cards in contact with the feed roller. That is, an outer card is brought in contact with the feed roller.
  • the card is then fed through the exit throat. Thereafter, the lifter is rotated back to its normal position and the remaining cards are brought out of contact with the feed roller.
  • FIG. 1 there is shown a perspective view of the apparatus of this invention.
  • FIG. 2 there is shown a sectional view of the apparatus taken along lines 2 2 in FIG. 1.
  • FIG. 3 there is shown a cross section of the apparatus taken along lines 3-3 of FIG. 1, a stack of record cards, and a portion of the apparatus housing.
  • FIG. 4 there is shown another view similar to FIG. 3 with the stack of cards fully inserted and with one of the cards being fed through the exit throat.
  • FIG. 1 in conjunction with FIG. 3, there is shown the card feeding apparatus of this invention generally designated by reference numeral 10.
  • Apparatus 10 is incorporated into a housing 20 having opening 21 through which a stack of record cards 22 is inserted during a loading operation.
  • Apparatus 10 is made up of a baseplate 7, a pressure plate 8, a card lifter 25, lifter rollers 4, a feed roller 18, and a pressure roller 5.
  • Baseplate 7 has fixedly secured thereto a throat piece 11.
  • baseplate 7 has integral tongues 15 for carrying lifter 25.
  • Opening 26 in lifter 25 is for receiving a shaft (not shown) which extends from sides 17 and is journaled in tongues 15.
  • Card lifter 25 is therefore rotatable about the shaft in opening 26, but is normally maintained in the position shown by solenoids or similar means represented by arrow 30.
  • Card lifter 25 has an angularly extending wing l on one end and' is connected about its other end to solenoids 30.
  • card lifter 25 carries freely rotatable card lifter rollers 4. With the components of the apparatus in the position shown in FIG. 3, a motor driven feed roller 18 has its axis of rotation on essentially the same plane with the axis of rotation of rollers 4 and 5, and has its upper periphery spaced below the upper periphery of rollers 4 (FIG. 2). In operation, roller 18 is to be continually rotated.
  • Pressure plate 8 Above baseplate 7 and lifter 25 is pressure plate 8.
  • Pressure plate 8 has an angularly extending wing 24 and integral hubs 28.
  • Pressure roller 5 is rotatable about a shaft 27 which has ends 16 extending through hubs 28 and the arms on one end of pivot member 19.
  • an expandable pressure throat is formed by wings I and 24 and rollers-4 and 5.
  • pressure plate 8 is raised against spring 6, and rotates about'shaft 27.
  • Member 19 will rotate about pins 13.
  • FIG. 4 wherein there is shown apparatus 10 with a stack of record cards 22 fully inserted therein.
  • pressure roller Sis acting against the uppermost card and urging stack 22 in. a downward direction under the influence of springs 6.
  • the lowermost card is acting against rollers 4.
  • a card 31 has'been partially ejected from apparatus It This was accomplished by lifter 25 being rotated in a downward direction by activation of solenoids 30. Lifter 25 was rotated downwardly to the extent that card3l was engaged by rollerl8. The downward movement of lifter 25 was followed by stack 22.
  • roller 18 can be made relatively large in diameter and length due to the fact that it is to be'continually rotated. With the wider width, much more reliable gripping is attained with a minimum of slippage.
  • Yet another aspect is that pressure is maintained on the stack 22 at two important places; between the rollers and in the vicinity of the exit throat (adjacent both ends of the cards). With pressure maintained at'these two points, there will be little likelihood of malfunction in terms of non-feeding or buckling of a card.
  • an operator can manually insert a stack of cards andbe insured that the bottom card is ejected when desired.
  • an operator will insert the cards through an opening in the housing enclosing the apparatus.
  • an expandable pressure throat made up of angularly extending wings integral with a rotatable card lifter and a ro- This resulted in card. 31 being partially driven through opening 23.
  • pinch rollers orother means for pulling card.31 com,- pletely through opening 23.
  • Drive roller 18 only drives card 31 a-sufficient extent to be pickedup by'the pinch rollers.
  • Lifter 25 and cards 22 must be raised by deactivation of solenoids 30 before card 3l clears the exit throat 23. This is to prevent roller 18 from ejecting another card.
  • feed roller 18 in the normal position the plane of the upper surface of feed roller 18' is below the upper surfaces of lifter rollers 4. Under the influence of springs 6, pressure roller 5 is'urged toward lifter rollers 4. Since feed roller 18 is a continually'rotating roller, the ejection of a bottom card is accomplished by lowering lifter rollers 4 for effectively bringing feed roller 18 I intocontact with the card. i I g
  • One important aspect of this invention is that the axis of rotation of rollers 4, 5,. and 18 essentially lie'on the same plane. This will eliminate any tendency of cards 22 to warp and thereby cause-a malfunction of the apparatus. This is not particularlyv important with a large tatable pressure plate.
  • a pressure roller connected to the pressure plate and forming part of the pressure throat, 2) card lifter rollers connected to the card lifter and forming another part of the pressure throat, and 3) the pressure'plate itself forcing the stack against a baseplatecarryingthe card lifter.
  • a feed roller is spaced from the pressure roller, and is located on the same plane with the pressure and lifter rollers.
  • the pressure plate is spring biased against the stack such that the stack is maintained intact in the vicinity of an exit throat and the entry throat.
  • the feed roller is a continually rotating roller which is brought into contact with an outer card on the stack each time the card lifter is rotated.
  • a'rotatable lifter means for normally. acting against said number of cards adjacent one end of said number of cards] and forming a part of an expandable pressure entry throat means;
  • a base means for normally supporting said number of cards adjacent both an exit throat and another end of said numberof cards and having carrying means for carrying said rotatable lifter means adjacent said expandable pressure entry throat means;
  • said pressure throat means also comprises a pressure roller carried by said pressure means and a lifter roller carried by said lifter means.
  • An apparatus further comprising a rotatable pivot means about one end of which said pressure means is rotatable.
  • An apparatus further comprising a housing enclosing said apparatus and having an opening communicating with said pressure throat means,
