Definitions

  • ABSTRACT A selector for edge notch coded sheet-type items comprising a plurality of parallel, spaced pairs of plates movable oppositely into projected and retracted positions and, in projected position, cooperating to address a desired sheet-type item in a store presenting edge notches to the address plates.
  • Magnet means which may be rotatably mounted, cooperates with magnetic means on the coded edge of the items tending to draw the items forwardly from the store, with all but the addressed item prevented from moving forwardly by the engagement of its edge with the edge of a projected address plate.
  • Solenoid operators and spring means cooperate in the opposite movements of the paired address plates of the selector, and the address plates have opposed racks engaged by pinions rotating on stationary axes for insuring simultaneous movement of the address plates in opposite directions.
  • Locking means temporarily holds the address plates in their address positions.
  • PATENTEHJMI 4m 3.631.978
  • the aforesaid issued patent shows a rotary store in which sheet-type items having magnetic means at their edges are edge coded by means of notches in any desired code, such as standard binary, binary coded decimal, Grey binary, octal, and like codes, which permit each individual sheet to be addressed by its identifying number and retrieved from a random storage position.
  • the selector of the patent employs address plates which are pivotally mounted and each rotatable into one of two alternate positions corresponding to binary and 1 numbers, and, by their position, addressing a unique sheet for withdrawal from the rotatable store by means of magnets eccentrically mounted relative thereto.
  • the selector mechanism of this invention may be used with sheet-type items disclosed in the patent, but is herein shown with a central extractor notch as disclosed in the aforesaid patent application.
  • the selector mechanism of the present invention is associated with the edges of edge notch coded sheet-type items which are mounted in side-by-side relationship in a store for relative movement with respect to the selector.
  • the selector comprises a plurality of pairs of parallel address plates which are moved in the planes of the plates, so as to project one and retract the other plate in each pair simultaneously.
  • the forward edges of the address plates coact with the coded edges of the sheet-type items to maintain nonaddressed items within the store and to permit addressed items to move partly forwardly by the notches in the item edges embracing the appropriate address plates, thereby moving the uniquely addressed item out of the store a limited distance.
  • the edge of the sheet-type item is provided with magnetic means which may, by way of example only, be a longitudinally extending clip of magnetic material which is U-shaped and embraces the edge of the item.
  • the coding notches may also be in this U-shaped clip.
  • the edge clip may be provided with a T-shaped slot which is adapted to receive an extractor, either adjacent the selector mechanism, or at a delivery station, or both.
  • Each pair of address plates is acted upon by biasing means and a solenoid actuator which cooperates to move the address plates in opposite directions, that is, the biasing means projects one address plate and retracts the other, and the solenoid operator retracts the one address plate and projects the other.
  • the movement of the address plates is such that one plate of each pair is projected into cooperating relation with the edge of the sheet-type item at all times, and latching means is provided for latching the address plates in their addressing positrons.
  • the selector may be used with eccentric magnets, as in the patent identified above, but is here shown as including a generally centrally located rotating magnet which engages and partially extracts from the store that item which is uniquely addressed by the address plates of the selector.
  • An item retainer may optionally be placed at the down-running side of the rotating magnet to engage and hold a partially withdrawn item out of the store against involuntary return thereto.
  • the address plates of each pair are provided with opposed integral racks which may be molded into the material of the address plates which, by way of example only. may be of phenolic resin base with suitable admixtures, such as fiber glass and tefion fibers, and meshing with the opposed racks of each pair of address plates are pinions freely rotating of fixed axis, which ensure transfer of the movement of one plate of each pair to the other in the opposite direction.
  • the forward surfaces of the address plates conform to the storage configuration of the items, in the present case they are of a circle, and engage with the forward edges of the items to restrain them in the store against withdrawal by the magnet of the selector.
  • helical springs bias one address plate on each pair forwardly, and a solenoid operator acts on the same address plate to retract it against the spring bias.
  • the biasing means and solenoid operator could be connected to different plates in the pair since the pair are interconnected by their racks and pinions to always have simultaneous movement in opposite directions into addressing positions.
  • the appropriate solenoids may be energized without effect and then the latching means released to effect simultaneous movement of the appropriate address plates by their springs and solenoids.
  • the selector is provided with an electric switch having an operator engaged by a withdrawn item whereby to stop relative movement between the sheets and the selector, as in the patent aforesaid, or the electric switch may control a slow down circuit to slow the travel of the items prior to reaching the delivery station.
  • FIG. 1 is a plan view of the selector according to the present invention.
  • FIG. 2 is a vertical sectional view on the line 22 of FIG. I;
  • FIG. 3 is a plan view similar to FIG. I, with parts broken away and solenoid elements omitted for clarity;
  • FIG. 4 is a detail sectional view showing the rack and pinion arrangement of the selector plates taken on line 4-4 of FIG. 3;
  • FIG. 5 is a horizontal sectional view taken on line 55 of FIG. 2.
  • the physical embodiment of the selector of the present invention illustrated in the drawings comprises a pair of sideplates 1 1 and 12, a backplate 13 to which they are connected by studs 14, and an irregularly shaped top plate 15 connected to the sideplates by studs 16. Between the sideplates II and 12 are mounted paired address plates 17 and 18in spaced stacked relation, there being illustrated 12 pairs of plates, although it will be understood that their number is immaterial to the invention and will be determined by the coding system adopted.
  • the sideplates II and 12 are provided with opposed, horizontally extending, vertically spaced notches 19, and the address plates 17, 18 are provided with opposite edge finger projections 21 and 22 received in the notches 19 to support and guide the address plate 17 and 18 for straight-line horizontal movement in the sideplates 11 and 12.
  • the opposed faces of the paired address plates 17 and 28 are provided with integral molded racks 23 and 24, as shown more particularly in FIGS. 3 and 4, the racks being paced at oppositesides of the address plates, as shown in FIG. 3.
  • Meshing with the cooperating paired racks 23, 24 are pinions 25 and 26 rigidly mounted on a shaft 27 which is journaled in bearings 28 mounted in the opposite sidewalls 11 and 12.
  • Movable plungers 31 are slidably disposed, in the notches 19 opposite each address plate 18 in back of the fingers 22.
  • the plungers 31 have guide pins 32 rigidly extending rearwardly therefrom and about which are disposed spiral compression springs 33.
  • the pins 32 pass through holes in, and the springs 33 are maintained by, backplates 34 mounted on the back edges of the sideplates 11 and 12, as by studs 35.
  • the springs 33 act on the plungers 31, which, in turn, bear against the fingers 22 to bias the address plates 18 forwardly in the selector into the position shown in the drawings.
  • solenoid actuators 36 having an armature 37 secured to an address plate 18, as by a stud 38.
  • Each solenoid actuator 36 and its armature 37 therefore operates, when energized, to retract the address plate 18 to which it is secured rearwardly against the bias of the springs 33 into the position opposite to that shown in the drawings.
  • the selector of this invention may be used with any kind of store, but is shown with a cylindrical store 41, similar to that illustrated in the above-identified US. Pat. No. 3,429,436.
  • a cylindrical store 41 similar to that illustrated in the above-identified US. Pat. No. 3,429,436.
  • the forward edges of the address plates 17, 18 are arcuate at 42 and 43.
  • the forward side edges of the address plates are notched at 44 and 45 to leave fingers 46 and 47 thereat.
  • the lockbar 49 has an arm 51 extending therefrom to which is attached a reciprocable member 52 secured at its back end to the armature 53 of a solenoid actuator 54.
  • a tension spring 55 connected between a stationary post 56 and arm 57 on the member 52 normally biases the locking bar 49 into the locking position shown in full lines in the drawings, form which it is adapted to be rotated to the unlocking, dotted line position of FIGS. 1 and 3 when the solenoid actuator 54 is energized.
  • a shaft 61 has reduced end portion 62 received in a complementary hole in the top plate of the selector.
  • the lower portion of the shaft 61 is supported in a hole passing through a supporting plate 63 extending between, and mounted on the sideplates 11 and 12 adjacent their lower portions.
  • the shaft 61 is held in the plate 63 by setscrew 64.
  • the address plates 17 and 18 are provided with elongated slots 60 which receive and provide clearance for the shaft 61.
  • the magnet assembly comprises a wheelike structure having a central bearing 67 of molded teflon or the like, about which is disposed an annular permanent magnet 68 of Alnico, ceramic magnetic material or other permanent magnet, and having pressed thereon discs 69 and 71 of magnetic material having integral peripheral pole faces 72 and 73 between which the magnetic flux passes through the-magnet material on the edge of the sheet-type item.
  • a U-shaped clip 76 Adjacent the central portion of the clip 76 is disposed a T-shaped notch 78 adapted to receive an extractor in the manner disclosed in the copending application previously identified, or the retainer shown herein, or both.
  • an electric switch 79 having an elongated operating arm 81 which acts as a sensor on the downstream side of the selector to be engaged by the edge of a partially withdrawn item to operate the switch 79 to indicate the withdrawal of an addressed sheet.
  • this may deenergize the rotating store 41, as in US. Pat. No. 3,429,436, or may slow the rotation of the store for a subsequent stopping of the sheet at a delivery station.
  • An optional feature of the selector is a retainer 82 rigidly mounted by an arm 83 to the sideplate 11, the retainer 82 having a T-shaped cross section conforming to the T-shaped notch 78 and engaging in the notch as an addressed sheet is withdrawn from the store into the position of the sheet 84 of FIG. 3 to retain a withdrawn sheet against involuntary return to the store.
  • the sheet 84 continues to rotate in the store 41, it will leave the retainer 82 before the delivery position, so that the notch 78 may be engaged by an extractor for movement of the sheet at the delivery station in X-Y directions, as in US. Pat. No. 3,429,436.
  • the selector of this invention may be mounted on a baseplate 58 which is supported on a table 59 which also supports the rotary store 41.
  • the selector is shown in the drawings with all of the address plates 18 projected into their forward positions by the springs 33 and with all of the address plates 17 thereby in retracted position.
  • the forward position of the address plates 18 may conform to either of the binary numbers 0 or I, and the reverse number be placed in each pair by projecting the address plate 17 forwardly.
  • the forward projection of plate 17 is done by energizing the solenoid actuator 36 connected to the address plate 18 of the pair. Normally, all of the solenoid actuators which are to be energized for a particular sheet address are energized, but without movement of their associated address plates, since they are locked in position by the lockbar 49.
  • the solenoid 54 is momentarily energized, thereby rotating the lockbar 49 to unlatching position, releasing the address plates 17 and 18, and permitting the address plates 18 attached to the energized solenoid actuators 36 to be pulled rearwardly, thereby projecting the paired address plates 17 into forward position, due to the interaction of the racks 23, 24 with the pinions 25. 26.
  • an address plate 18 be locked in retracted position and its solenoid actuator not be energized, it will, when unlocked, by move forwardly by its springs 33, thereby retracting the paired address plate 17.
  • the solenoid 54 After movement of the address plates, the solenoid 54 being deenergized, the lockbar 49 is returned to locking position by the bias of spring 55, and thereafter the solenoid actuators 36 may be deenergized without affecting the settings of the address plates which are locked in their address positions by the bar 49.
  • Relative movement transversely of the items in the store 41 relative to the selector may be effected by moving either part, for example, by rotating the store 41, as in US. Pat. No. 3,429,436.
  • As an item 75 approaches the magnet 65 its magnetic edge 76 will be attracted thereto and the magnet 65 will rotate therewith.
  • unaddressed sheets will be prevented from leaving the store because of the engagement of the edge of the item with the forwardly projected surfaces 42 and 43 on the address plates 17, 18 which do not conform to the sheet notch coding at 77.
  • notches 77 will be disposed opposite the projected edges of the address plates, and as the item moves to the runoff side of the magnet 65, the item will move outwardly from the store by the limited distance provided therefor by the cooperating notches and address plates.
  • Such a sheet is illustrated at 84 in FIG. 3, where it has moved out of the store and its central T- shaped notch 78 has been engaged by the T-shaped retainer 82.
  • This sheet 84 is now in a position to give a downstream sensing of its withdrawal on the addressed sheet for whatever further action is programmed into the apparatus, as for example, is disclosed in US. Pat. No. 3,429,436.
  • eccentric magnets of US. Pat. No. 3,429,436 may be used instead of the rotary magnet 65 to withdraw the sheet-type item from the store and the retainer 82 omitted from the selector structure.
  • a selector for edge notch coded sheet-type items mounted in a store comprising:
  • magnet means associated with the selector and cooperating with the magnetic means on said items for partially withdrawing an addressed item from the store
  • a solenoid actuator for releasing said locking means to permit movement of said address plates into a new address position.
