Definitions

  • This invention relates to machinery for handling datatabulating cards. In particular, it concerns an improved mechanism for step-by-step advancing of such cards.
  • the reading and punching equipment is arranged to handle an entire line, for example a row of up to eighty punch cations, in a single operation. Since there may be many such rows on a card, after each operation the device must advance the card one row so that the following operation is performed upon the next succeeding row.
  • the object of this invention is a device for performing the stepwise or line-by-line advancing of the cards through the reading or punching station. It will be appreciated that for such a device the problem of frictional Wear at high operating speeds is many time more acute than it is even for the other parts of a card-handling machine, because while other parts may go through one operating cycle per card, the advancing mechanism we are concerned with performs an operating cycle for each row, and there may be, for example, twelve such rows on each card.
  • this invention aims to provide a mechanism of this type which eliminates sliding friction in the suspension of the card-advancing member.
  • An additional object is to provide a suspension for a card-advancing member which has no backlash.
  • a further object is to provide a suspension for a card-advancing mechanism which is relatively inexpensive to manufacture.
  • a further disadvantage of prior structures relates to the temporary halting of the card-feed while the card-advancing mechanism continues to go through its operating stroke. Under these conditions it is found that there is a further wearing of the cards, and of portions of the cardhandling machine in addition to the card-advancing mechanism. Therefore it is an additional object of the invention to prevent such further wear.
  • An illustrative example of a card-advancing mechanism embodying this invention and exhibiting these and other advantageous features comprises a support and at least one flexible mounting member secured to the support and projecting therefrom.
  • the card-advancing member is then mounted on the projecting part of the mounting member, and the latter is sufficiently bendable to permit the card-advancing member to move relative to the support through its card-advancing stroke.
  • the card-advancing member is selectively retracted from contact with the data cards and the bed plate therebelow during the time that cards are not being fed, and is moved back into operative position thereafter.
  • the mechanism for retracting the card-advancing member is also of lowwear construction, in accordance with the principles referred to above.
  • a means for disengaging the card-advancing member from its drive while the latter continues to operate includes an armature secured to the caradvancing member and positioned to be engageable by its reciprocating driver. Cooperating therewith are means on the driver adapted to releasably engage the armature to establish a iii-directional driving connection to the cardadvancing member.
  • An electromagnet is fixed near one of the limits of reciprocation of the armature and is adapted to, when energized, magnetically engage the armature to latch the card-advancing member in its limit position and thereby disrupt the driving connection. Then means, which may be under some kind of automatic control, are provided to energize the electromagnet so as to select between operation and idling of the cardadvancing member.
  • FIG. IA is a side elevational view of a card-advancing mechanism embodying features of this invention.
  • FIG. 13 is an enlarged detail of a portion of PEG. IA;
  • FIG. IC is a side elevational View, similar to FIG. IA, of a card-advancing mechanism embodying further features of this invention
  • FIG. HA is a perspective view of an alternative drivessence o) ing mechanism for the card-advancing structure of FIG. IA;
  • FIG. llB is a schematic diagram illustrating electrical and electromechanical details of the structure of FIG. HA.
  • FIG. IA shows a line-by-line card-advancing mechanism designed for use in an operating (i.e. reading or punching) station h of any type of data-card-handling' device.
  • the term line-by-line is used in this specification and the appended claims to include either a row-by-row or columnby-column card feed, but the particular mechanism used herein to illustrate the invention is of the row by-row type.
  • This mechanism includes a bed plate it? which acts as the base for a feed path over which the data cards such as C are advanced through the reading or punching station. The cards lie flat over the bed plate ill and are fed thereacross from left to right as seen in H6.
  • each card having its width dimension (the direction of a column of hole locations) arranged in the left-right direction, and its length dimension (the direction of a row of hole locations) extending perpendicularly to the plane of the drawing.
  • the cards are initially delivered to the operating station 9 by a pair of cooperating upper and lower feed rollers ii, the lower one of which operates through a suitable aperture ltia in the bed plate it).
  • the lower roller is relieved over a portion of its periphery at Illa, so that for a part of each cycle the rollers llll are disengaged from the card C.
  • advancing of the card C is performed under the influence of a stepwise cardadvancing device, generally designated 12, which advances the card through the operating station 9 one row at a time so that each individual row is handled in one unit operation.
  • This device 12 includes a row of twelve (one for each hole row) flexible spring steel pusher blades 14 (of which four are shown) and a blade carriage 16 overhanging the bed plate ll) which mounts this row of pusher blades 14 with each blade extending therefrom diagonally downward and in the direction of the card feed.
  • the lower tip of each pusher blade 14 is flexed resiliently against the bed plate it) and/or against any data cards that may be on the bed plate directly below the advancing device 12.
  • the cardadvancing device 12 is reciprocated horizontally through a stroke having an amplitude of slightly more than one data card row, that is, slightly more than the distance which must be advanced after each operation to move the next succeeding row into operating position.
  • a suspension for the card-advancing device 12 which permits it to reciprocate very rapidly through its advancing stroke but which avoids the various disadvantages of bearings with their attendant rotary or reciprocating friction.
  • Four mounting members 2d consisting of flexure springs made of strip-shaped leaves of high quality flexible sheet material, suspend the card-advancing device 12 at the four corners thereof, and bend to allow it the required latitude of horizontal movement.
  • these mounting springs TAB are secured to a supporting member 22 by means of pairs of clamping bars 24 and 26 which clasp the ends of the supporting springs between them, the entire assembly being secured to the supporting member 22 by bolts 28.
  • a similar structure is used to engage the lower ends of the mounting springs 13%, consisting of clamping bars 353 and clamping brackets 32 secured by bolts 34 with the lower ends of the mounting springs in clasped therebetween.
  • the clamping brackets have horizontal extensions 32a which are secured to the blade carriage 16 by bolts such as 36.
  • the clamping bars and clamping brackets are provided with gentle curvatures as indicated at th in FIGS. IA and B so as to minimize the tendency for the bending stresses exerted on the supporting springs to be concentrated at the point where they emerge from between the clamping bars and brackets.
  • the horizontal oscillating drive for the advancing member is provided by a rotating drive shaft 5t) carrying a gear 52 which drives an idler gear 54 mounted on an auxiliary shaft 56.
  • the idler gear 5 in turn drives a gear 58 affixed to an advancing device drive shaft as which carries on both ends thereof eccentric pins 62.
  • the latter are received at the center of bearings 6 mounted in yokes 66 formed on reciprocating drivers 68, which have extension arms 70. Only one each of the elements 624 i) is seen in the side view of FIG. IA. As pins 62 rotate eccentrically, they crank the yokes 66 through a motion having both horizontal and vertical components.
  • flexure springs '72 In order to transmit only the horizontal component of this motion to the advancing device 12, there are provided flexure springs '72, one of which is seen. One end of each such spring is secured to one of the extension arms '70 by bolts 74, and the other end to the blade carriage 16 by bolts '76. In view of the short strokes involved, flexure springs '72 are able to operate both in tension and in compression to transmit horizontal oscillating motion to the advancing device 12, while flexing slightly to accommodate the vertical rocking of the extension arms 7tl which results from the vertical motion of the yokes 66.
  • the solid lines of the drawing illustrate the advancing device 12 in its fully rearward position, after it has been drawn back to pull the first pusher blade 14 behind the trailing edge E of the card C, and before beginning the forward stroke which will advance the card to the next row position. It is readily seen from the drawings that it is the bending of the mounting springs 20 which allows the advancing device 12 to be drawn to this position by the reciprocating driver es.
  • the fully advanced position of the advancing device 12 is illustrated by the broken lines of FIG. IA, showing that it is again the bending of the mounting springs 20 which permits the reciprocating driver 68 to move the advancing device 12 to that position.
  • the flat shape of the springs 2d is adapted to permit this reciprocating motion perpendicular to the planes that the springs define, yet it offers sufficient rigidity parallel to those planes to restrain motion in any direction other than perpendicular thereto.
  • the advancing device 12 may be greater than the thickness of the tabulating card C, such height is not achieved until the advancing device is close to the limits of its horizontal travel, the advancing device is less than 0.007 inch above its bottom position and therefore the pusher blades 14 would in any event remain in engagement with the edge of the card C.
  • the flexibility of the pusher blades 14 enables them to be compressed against the bed plate and data card C when the advancing device 12 is at its lowest position, and thus to spring back and remain in engagement with the edge E during the remaining 0.002 inch of the rise of the advancing device 12.
  • Disengagement Mechanism In some tabulating card applications it is necessary, from time to time, to halt the feeding of cards through the operating station 9. For example, with reference to FIG. 1C, it may be necessary to stop a card D as it enters a punching station 9 but before it is advanced therethrough by the advancing mechanism 12, so that information printed on the face of the card D can be scanned and read by character recognition equipment and then subsequently punched on the card when line-by-line advancing thereof is resumed.
  • the drive mechanism 68, etc., for the advancing device 12 is kept running so as to be constantly ready for the resumption of advancing operations, since the inertia thereof is such that a delay in accelerating the drive might impair the critical timing relationships between the punching equipment and the subsequent line-by-line advance of the card.
  • the advancing device 12 would continue to move under the influence of its reciprocating drive 68, etc., while the pusher blades 14 thereof remained in contact with the bed plate 10 and/ or any card D then at the threshold of the operating station 9; such card D not being far enough advanced for its trailing edge E to be engaged by any of the pusher blades 14 as in the case of the card C illustrated in FIG.
  • the support 22 from which the advancing device 12 is suspended by the mounting springs 20, is itself moveably suspended at each corner by means of four similar but horizontally oriented mounting springs 80, of which tWo are visible in the drawings.
  • the support 22 includes clamping blocks 82 to which the springs 30 are clamped by means of clamping bars 84 secured to the blocks 32 by bolts 86.
  • the other ends of the springs are similarly clamped to the fixed frame 88 of the card-handling machine by means of a clamping bar 90 and a clamping bracket 92 secured thereto by bolts such as 94.
  • a bracket 120 bolted to the support and a link 122 pivotally connected thereto by a pin 124.
  • a lever 126 is pivoted upon a shaft 128, the short arm of this lever 126 being pivotally connected to the link 122 by a pin 130 so that clockwise rotation of the lever about its fulcrum (shaft 128) drives the link 122 downwardly to effect the desired lowering of the support 22 and advancing device 12.
  • a solenoid 132 secured to another part of the fixed machine frame 88 has its armature 134 connected to the long arm of the lever 126.
  • connection is made by means of a block 136 which is rotatably secured to the armature 134 by a pin 138 and which rides slideably within a slot 126a formed in the lever 126.
  • a return spring 14.0 is connected at one end to a pin 142 on the long arm of the lever 126, its other end being connected to any suitable place on the machine frame to provide a restoring force which raises all the previously lowered parts to their Original positions after such energization is terminated.
  • the mounting springs till which suspend the support 22 from the frame 88 provide an inexpensive, no-friction, no-backlash, no-lubrication, longlived mounting.
  • the advancing device 12' is seen to be supported as before by means of fiexure springs 20, and a pair of reciprocating drive arms 68' are horizontally oscillated by means of an eccentric drive, in this case a pair of bearings 160 which are centrally rotatable within the yokes 66 formed on the reciprocating drive arms 68' but which are eccentrically mounted upon a rotating drive shaft 6&9.
  • the projecting ends of the reciprocating drive arms 68' are suspended against vertical movement by flexure springs 162 which, however, bend to allow the appropirate degree of horizontal movement to the reciprocating drive arms 6%.
  • the upper ends of these springs 162 may be anchored upon a portion (not shown) of the fixed machine frame. All the flexure springs 2d and 162 are clamped at both ends using gentle curvatures in the same manner as shown in the preceding figures.
  • An armature 164 consisting of a bar of magnetic material is secured to the top surface of the blade carriage 1d, and is situated forwardly of the reciprocating drive arms 68 and directly in the path of their forward advancing stroke, which is from right to left as seen in FIGURE IIA.
  • a switch 169 (FIG. HE) is thrown to terminate energization of the coil res and energize instead another solenoid coil 17ft Wired as seen in FIG. I113.
  • the latter coil along with its core bar 172, which is secured in any conventional manner by means of lugs 174 to a portion (not shown) of the fixed frame of the machine, forms a second electromagnet which is fixed in position at the forward limit of reciprocation of the armature 164.
  • energization is switched back to the moving electromagnet 166, 168 by means of switch 169.
  • Each of the electromagnets 166, 15% and 17%, 172 is designed to have sufl'icient attractive force when energized to override any residual magnetism remaining in the core oar ice or 17% of the other electromagnet after energization of the latter has been terminated.
