Definitions

  • This invention relates generally to card sorting or selecting apparatus and particularly to an improved air nozzle used in a system in which a predetermined card in a pack of cards is located and identified by moving it relative to the remainder of the pack by means of an air stream passed through the nozzle and across the surface of the cards.
  • Card selecting or sorting systems generally are well known and have been commercially available for sometime.
  • One such commercially available card selecting arrangement employs cards made with a series of holes along one edge. Individual cards are classified by punching out the material adjacent certain holes to form notches according to a desired code. One or more rods or needles are passed through the holes or notches in the entire pack thereby holding those cards having holes but permitting the cards having notches to move relative to the rods. Separation is made by lifting the needles or by dropping the bottom of the container.
  • a stream of air from a nozzle is then passed upwardly against the bottom of the stack of cards in the container.
  • the nozzle is preferably moved transversely relative to the cards so as to insure uniform exposure of all cards to the air stream thereby causing the selected card to rise until the notches engage the selected bars.
  • the selected card- is raised above the others and is heldin the-raised position by friction between adjacent cards. With the selected card held in the raised position, all of the barsmay then be withdrawn so that the selected card may be'removed manually or automatically.
  • Another objective has been to provide an air nozzle for use in apparatus of the type described in which card selection is achieved rapidly without subjecting the cards to substantial fluttering during their exposure to the air stream.
  • Another objective of this invention has been to provide a card selection apparatus in which the selected cards are positively separated from a stack of cards.
  • the air blast nozzle ismoved laterally across to the bottom of the stack so that the stream of air is passed upwardly against the bottom of the cards.
  • the pressure of the air on the bottom edge of the cards together with the relative drag of the air upon the surface of the cards as it penetrates the pack and moves between the cards causes the preselected coded card which is unrestrained to pop up out of the pack so that it is physically differentiated from the remaining cards.
  • the selected card is held in this outward position or physically diifere ntiated position by frictional contact of the adjacent cards against the surface of the selected cards.
  • This invention is an improvement upon previously known card selecting apparatus which utilizes an air stream passing over the surface of the cards to move the cards into a physically differentiated position.
  • the air stream has a tendency to cause the cards to flutter while they are held suspended in the air blast. This flutter or vibrational movement produces objectionable noise and is undesirable because of the wear which it causes upon the surface of the cards and the mechanical attrition to which it needlessly subjects the cards.
  • the flutter results when the air pressure across one flat surface of the card is approximately equal to the air pressure across the opposite face of the card so that any infinitesimal unbalance between these pressures causes the card to move toward one side, then the other, in a direction normal to the direction of flow of the air current.

  • FIGURE 2 is a cross sectional view taken along line 22.of FIGURE 1,
  • FIGURE 3 is a crosssectional view taken along line 33 of FIGURE 2,
  • FIGURE 4 is a cross sectional view taken along line 3 ,292,639 Patented Dec. 20, 1966.
  • a plurality of coded cards are held in stacked relation between a pair of spacer blocks or container end walls 12 and 13 and a pair of side walls 7 and 8, the side walls having bars 9 extending from their bottom edge in a position to support the lateral edges of the deck of cards.
  • the spacers 12,13 may be in the form of spacers in a container 5 or a file drawer or any device which would be capable of holding the cards in stacked relation.
  • the cards are each coded along their upper edge so as to be selectible from the stack according to a coding schedule.
  • the coding consists of a plurality of vertical notches 14 which extend inwardly from the upper edge of the cards.
  • the notches are so located in the horizontal plane of the upper edge as to be engageable with any one of a plurality of selection bars 15, 16, 17, 18 and 19.
  • the selection "oars are located over the top of the stack of cards in a position to be selectively movable into a horizontal plane immediately above the top surface of the cards. For purposes of illustration, five bars have been shown, although of course, any number of selection bars could be used in a card selection apparatus of'this type.
  • the bars 16 and 18 are moved into a position immediately above the stack of cards from a withdrawn position either above the plane of the cards or from a position behind the stack of cards. An air blast is then passed beneath the cards which forces the cards upwardly against the bottom edges of the bars 16 and 18. Any card which has notches in a position immediately below the bars 16 and 18 will be moved upwardly 'by the air blast to a position in which the notches surround the bar 16, 18. If only one card 11 is coded so as to have notches in the vertical plane of the selection bars 16, 18 only that card will be moved upwardly above the plane of the remaining cards in the stack.
  • any other combination of preselection bars could be moved into .a position immediately above the stack to select cards having notches corresponding to other combinations of selection bars.
  • the selected card is held in a physically separated or raised position above the plane of the remaining cards by the friction of the selected card resting against the surface of the adjacent cards on each side or by the friction of a selected card resting against the surface'of a spacing' member 13 and an adjacent card 10.
  • the selection bars are then withdrawn or removed so that the cards 'may be withdrawn manually or automatically.
  • the apparatus utilized to physically separate the cards according to the selected code as determined by the selection bars located above the stack of cards consists of an air blast system having a nozzle 20 which is passed below the stack of cards in the direction indicated by the arrow 21 of FIGURE 3.
  • the stack of cards may he moved relative to the nozzle rather than moving the nozzle relative to the stack of cards.
  • nozzle may be circular in cross section at the 'bottom the outlet orifice is located preferably in a vertical plane 7 approximately parallel to the vertical planes of the cards so that as the nozzle is moved laterally with respect to the stack of cards, as in the direction of the arrow 21,
  • bridges 25 are provided across the outlet orifice of the. These bridges may be integral with the nozzle nozzle.
  • the bridges are in the form of integral thin sheet metal tabs of substantial width which are bent over and extend across the outlet orifice adjacent the outlet of the orifice. By interrupting the unidirectional flow of the air, the bridges 25 create areas of relatively static air under positive pressure above each of the.
