Definitions
- ABSTRACT A feed mechanism for punch cards or like sheet material whereby the punch card is quickly advanced and accurately positioned at a work station.
- the trailing edge of the punch card is used as a reference to register the punch card at the work station.
- the advance ment and final registration are the result of two synchronized steps involving a register roll and a pusher blade.
- the register roll is effective during the first step to rapidly advancethe trailing edge of the punch card into operative relationship with the reciprocating pusher blade; the latter at the commencement of the second step is cooperatively positioned to pick up the trailing edge of the punch card and carry it forward into final registration with respect to the work station.
- the final registration involves the positioning of the punch card such that the first and second columnar positions are accurately aligned with respect to corresponding punches of a punch mechanism. Once registration has been effected, further advancement of the punch card is accomplished by somewhat independent indexing means.
- the system is further adapted to ac comodate punch cards of different lengths.
- the present invention relates to a feed mechanism for punch cards and the like and more particularly to a feed mechanism adapted to rapidly advance a punch card, or like sheet material, from a supply and very ac curately position each punch card with respect to a reference point within an associated data processing system such that subsequent operations including the punching and printing of the punch card may be per formed with a high degree of accuracy, i.c., with assurance that the punch card is properly positioned to receive such information.
- the present invention overcomes the deficiencies of the prior art in that a punch card after being delivered from an input hopper is advanced to a visible station where previously entered information may be visually observed by the operator.
- the punch card remains in the visible station until released by the Operator at which time the card is advanced to the next work sta tion.
- the succeeding work station comprises a punch mechanism, the punch card being advanced thereto and accurately positioned with respect to indexing means comprising a part of the punch station.
- the register roll assembly includes a regis ter roll and a synchronously driven pusher blade both being activated by a single-cycle wrap-spring clutch.
- the rapid advancement of the punch card is accom plishcd by the register roll and a cooperating pinch roll.
- the pusher blade executes a reciprocative motion whereby the punch card is advanced into final registration at a work station.
- the wrap spring clutch after being energized is designed to complete one revolution of an associated output shaft on which the register roll is mounted and to which the pusher blade is mechanically linked by means of a cam follower assembly. This results in turn in one revolution of the register roll and correspondingly one reciprocative cycle of the pusher blade.
- the register roll and its cooperating pinch roll engage the punch card and advance it to within a short incremental distance of final registration with respect to the indexing system at the work station.
- the cam controlled pusher blade picks up the trailing edge of the card and carries the card into final registration with the indexing means comprising a portion of the work station.
- a significant feature of the register roll assembly con cerns the provision of a substantially flat section on the periphery of the register roll. At the beginning and end of each operative cycle of the subject advancement and positioning mechanism the flat section of the register roll is positioned parallel to the path of travel of the punch card.
- the resuitant separation between the register roll and the pinch roll permits a substantial portion of a punch card, being advanced by independent means from an input hopper, to pass thercthrough prior to the initiation of an operative cycle of the register roll as sembly.
- the pusher blade is designed to rccip rocatc in the path of travel of the punch card; however, the blade is equipped with ramp shaped surfaces and is mounted on a flexible spring steel member such that the blade is readily moved aside by an oncoming card and continues its reciprocatory motion on the face of the punch card without apparent damage thereto.
- the positioning mechanism of the present invention should not be confused with simpler prior art arrangements which rely on the use of the leading edge of a punch card for reference purposes. Such arrangements very conveniently interpose a stop in the path of a punch card to assure the accurate positioning thereof.
- An example of such a leading edge positioning device is disclosed in the U.S. patent to Suzuki ct al, Pat. Nov 3,636,3 l6. Although much more simple to implement, leading edge referencing techniques have other deli ciencies which limit their usefulness in data processing equipment.
- Still additional flexibility would be afforded by placing a number of register roll assemblies in line and operatively interconnecting these by means of an appropriate control system such that a punch card would be advanced by more than one of the register roll assemblies but only the last of the assemblies would be effective in positioning the card.

I there is illustrated an elevational view of a card advancing and positioning mechanism 10 embodying the principles'of the present invention and illustrating a punch card 12 positioned in the visible station" of a card preparation and interpretation apparatus such as is disclosed in the patent to Me- Pherson et al filed Nov. 16, 1970 as Ser. No. SL250 now U.S. Pat. No. 3,706.074.
- the visible station dimensionally speaking. comprises an area which is slightly larger than the surface area of a punch card, and in the embodiment of FIG. 1 encompasses essentially all of the area beneath a plexiglass cover identified therein as member 14.
- FIG. 1 further depicts the relative position of the punch card 12 in its path of travel from the preceding work station the latter being herein depicted as a read station identified by feed rolls 16 mounted on shaft 18 positioned within brackets 20.
- the punch card After being released from the visible station by the operator, in the manner discussed further hereinbelow, the punch card is advanced to a punching station depicted generally herein as member 21 and comprising a plurality of rectangular punch pins ZZA and 22B. :1 pair of which are mounted within each of 12 cylindrical apertures 24. Details of a punch mechanism which may be used in conjunction with the present invention are disclosed in FIGS. 19, 20 and 21. and reference is now made thereto.
- the plural punch pins 22A and 22B are selectively actuated within a punch guide 26 by means of a conventional high speed punch mechanism of the interposer type.
- actuating means comprising a flexure mounted bail 27 which carries an interposer 29 for each of the punch pins.
- the interposer being connected at one end to a rocker arm 31.
- the latter includes a cam follower portion 31A which is normally spring biased by a spring 34 against a cam shaft 36.
- the shaft 36 is mechanically coupled to a crank shaft 33.
- a connecting rod 33A carrying a drive link 338.
- crank shaft 33 The rotational motion of crank shaft 33 is translated into reciprocating motion by way of the connecting rod 33A and this motion is in turn effective in moving drive punch pins 22A and 2213 into punch relationship with a corresponding location of the punch card 12 depending on the position of the interposer 29.
- punch logic In the event it is not desired to make an entry on the punch card in a particular location, appropriate control signals are generated in punch logic (not shown); these signals in turn are used to selectively energize a coil 35 which in turn magnetically latches the armature portion of the rocker arm 31 after the latter has been rotated about its pivot point 31B such that the armature is moved into close proximity of coil 35 by means of the cam shaft 36.
- punch pins 22A and 22B facilitate the simultaneous entry of information into up to two adjacent columns of the punch card 12 when the latter is properly positioned with respect thereto.
- Indexing means comprising an index roll 28 and a retractable pinch roll 30 are adapted to engage the punch card 12 after the latter has been properly positioned at the punch station.
- the index wheel 30 is mounted so as to permit a slight separation to be introduced between it and the index roll thereby facilitating the uninhibited entry of the punch card therebetween during the card advancing and positioning operation.
- the pinch roll 30 is mounted on an arm 32.
- a spring 34 urges the pinch roll 30 toward the index wheel 28.
- a coil 37A of a solenoid 37 when energized, by means of a signal OPR discussed hereinbelow, attracts and holds the arm 32 thus moving the pinch roll away from the index wheel 28 sufficiently to permit a punch card to be readily positioned therebetween.
- the index wheel 28 is mounted on a shaft 39 which in turn is mounted in bracketed bearing 41, the shaft 39 being in turn driven by a servo system indicated generally as member 45.
- a register roll assembly identified generally as member 43 is seen in the embodiment of FIG. 2 as being mounted adjacent the back plate 40.
- a more detailed representation of the register roll assembly 43 is depicted in FIG. 8, being shown therein as comprising a housing 44 which carries a register roll shaft 46 and a pusher blade and follower arm shaft 48.
- Vertically spaced register rolls 50 hereinafter sometimes referred to as drive rolls, are provided with a flat portion 500 covering a substantial portion of the periphery thereof, are mounted on the register roll shaft 46.
- the register rolls 50 are positioned to cooperate with pinch rolls 52 during all but that portion ofa revolution thereof during which the flat section 50a of the register rolls 50 are oriented proximate to the pinch rolls 52.
- the function of the flat sections 500 of the register rolls 50 is to thereby provide a gap between the register rolls 50 and the pinch rolls 52 so as to facilitate the transmission of a substantial portion of a punch card therethrough by means of feed rolls 16 prior to the initiation of an operative cycle of the register roll assembly.
- the relative percentage of the flat section 50a compared to the balance of the peripheral surface on a roll 50 determines the extent of advancement capable of being imparted to a punch card by this means.
- a specially configured pusher blade 54 which, as is seen more clearly from FIGS. 11 and 12 is flexure mounted by means of a flat section of spring steel 56 to a pusher arm 58 which in turn is adjustably mounted on the shaft 48 by means of clamping screws 60.
- clamping screws 60 In addition to the rather coarse adjustment afforded by clamping screws 60, provision is made for fine adjustment of the punch card engaging surface 54a of the pusher blade 54 with respect to the punch card 12; this appears in the form of a fine adjusting screw 62 in the embodiment of the pusher arm 58 disclosed in FIG. 11.
- a ramp shaped configuration has been imparted to the card contacting surfaces of the pusher blade 54 to enable a punch card to uninhibitedly ride underneath the blade independent of the direction of relative motion of the pusher blade with respect to the punch card.
- a cam follower assembly comprising a follower arm 64 clamped on shaft 48 by means of a clamping screw 66, as may be seen from FIGS. 13 and 14.
- the follower arm 64 carries a freely rotating roller 68.
- the roller 68 cooperates with the specially configured surface of a cam 70 mounted on the register roll drive shaft 46 to cause reciprocation of the pusher blade upon rotation of the shaft.
- the roller 68 is held in contact with the cam 70 by means of a tension or retaining spring 72 connected at its ends to posts 74 and 76.
- the posts 74 and 76 are supported on the housing 44 and follower arm 64 respectively.
- the drive means for the register roll assembly 43 preferably comprises a wrap spring clutch 80 which is mounted on the register roll shaft 46.
- the wrap spring clutch used in the preferred embodiment of the present invention is of conventional design, a suitable form of which is supplied by Precision Specialties, Inc. of Pitman, N.J., the same being described in detail in US. Pat. No. 3,373,851.
- the wrap spring clutch 80 activated upon release of a clutch pawl 82 (FIG.
- register roll assembly 43 will now be described with reference to FIGS. 1 through 7. It should be noted that prior to the time the register roll assembly is actuated, a substantial portion of the punch card will have already been advanced through the gap separating register roll 50 and pinch roll 52. This initial advancement of the punch card 12 is unhampered by the register roll assembly in that the fiat section 50A of the register roll 50 is positioned proximate to and parallel with the back plate 40 thus permitting the punch card to pass freely between the register roll 50 and Ila associated pinch roll 52. Further. the flexure mounted nature of the pusher blade 54 permits the latter to ride up and over the advancing punch card.
- the flcxure mounted nature of the flat section of the spring 56 assures that as the card continues to advance, no damage will be rendered to the surface thereof even during the initial portion of an operative cycle of the register roll assembly during which time the pusher blade is moving in a direction opposite to the direction of the advancing punch card.
- substantially all of the punch card 12 is visible to the operator while the punch card remains in the position of FIG. 1.
- the operator is thus free to assimilate any information from the punch card which may be needed in further preparation of the same or yet another punch card.
- a release key on the keyboard of the associated data processing and preparation is depressed.
- the signal generated thereby in turn actuates a solenoid connected to the clutch pawl 82 of FIG. I which in turn releases the wrap spring clutch initiating one revolution of the register roll shaft 46.
- Subsequent positions of the register roll 50, the pusher blade 54 and the punch card I2 are seen in FIGS. 3 through 7 as the punch card is rapidly advanced and finally becomes accurately positioned with respect to the punch station.
- the register roll 50 has rotated through ap' proximately to a point where the periphery thereof is now in cooperative relationship with respect to the pinch roll 52 so as to drive the punch card 12 toward the punching station.
- the clockwise rotation of the register roll 50 as indicated in FIG. 3 drives the punch card 12 to the observer's left.
- the pusher blade 54 has been partially retracted from its most forward position, i.e., the position assumed during final registration of the preceding punch card. Accordingly, the card-cooperating-surface 54a of the pusher blade is now approximately in line with the center line of the register roll shaft 46 and the pinch roll 52.
- the punch card l2 advances toward the punching station until as seen in FIG. 4, after the register roll has rotated through approximately 200 from the start position the trailing edge 12A of the punch card passes over the center line connecting the register roll shaft to the pinch roll 52 and thus drops-out of drive relationship with respect thereto. At this point in time the pusher blade 54 is in its fully retracted position.
- the register roll shaft 46 continues to rotate; however, the trailing edge of the punch card remains stationary having dropped-off" the register roll after having passed over the center line bisecting the register roll shaft 46 and the pinch roll 52. After completing some 235 of rotation, the pusher blade 54 moves into contact with the trailing edge of the punch card.
- the preferred embodiment of the present invention provides means for separating slightly the index wheel 28 from its cooperating drive position with respect to pinch roller 30. This slight separation between the index wheel 28 and the pinch roll 30 remains until such time as final registration of the punch card 12 has been achieved.
- the pusher blade 54 continues to advance the punch card toward the final registration point at the punching station and at the conclusion of the single revolution this position has been achieved.
- the index wheel 28 is moved into restraining contact with the surface of the punch card 12 and further advancement of the punch card is subject to the control of the indexing mechanism.
- the indexing mechanism as well as the punching mechanism may take the form of devices well known in the art in that the specific details of the indexing and punching mechanisms form no part of the instant invention.
- FIG. 16 dis closes an alternative embodiment of the present invention designed to accommodate punch cards of varying lengths and particularly adapted to accommodate the very popular column and 51 column punch cards.
- register roll assembly 43A of FIG. 16 is opcrativcly constructed in the same manner as the corresponding assembly of FIG. 1 while the register roll assembly 43B of FIG. 16 is similarly constructed but operatively differs slightly from assembly 43 of FIG. 1. More specifically, the register roll assembly 438 of FIG.
- the register roll assembly 438 is designed to accommodate SI column punch cards which, being proportionately shorter than the 80 column variety, necessitates that the register roll assembly 438 be positioned closer to the punch station than the corresponding assembly handling 80 column punch cards in order that final registration of the punch cards can be accommodated in the same manner. In order to insure the capability of accommodating 80 column punch cards in the same system, the register roll assembly 438 must necessarily be displaced further from the feed roll 16 than is the corresponding assembly 43A. 7
- the distance between the drop-off point of the register roll 50B and the drop-off" point of feed rolls I6 is less than the length of a 51 column punch card.
- FIG. 16 The alternative embodiment of the invention disclosed in FIG. 16 is implemented in such a manner that when the unit is being used to process 5l column cards a switch on the keyboard (not shown) is set to indicate this condition whereafter all subsequent operations are effected automatically in accordance therewith. Since in the processing of the 51 column card the 80 column card register roll assembly is not needed it remains unactivated. By reason of the flat 50a on the register roll 50 and the flexure mounting of the pusher blade 54, the 51 column cards may be advanced from the feed roll 16 to the register roll assembly 43B unhindered by the register roll assembly 43A.
- the embodiment of FIG. 16 with slight alterations could be used to process punch cards of shorter length.
- the so called soap cards, so designated because of their common usage as a promotional coupon included in a carton of soap powder could be processed by modifying the embodiment of FIG. I6 to include yet a third register roll assembly to be positioned between the register roll as sembly 43B and the indexing assembly comprising the index roll 28 and the pinch roll 30.
- register roll assembly 43A would pick up the soap card from the feed rolls l6 and advance it during the initial portion of its operative cycle to register roll assembly 438 which in turn would advance it during the initial portion of its operative cycle to a position where the newly added register roll assembly could complete the advancement and final registration of the soap card at the work station. It should be noted that by properly timing the operative cycles of both register roll assembly 438 and the newly added register roll assembly with respect to the energization of register roll assembly 43A, it would be possible to ignore the pusher blade registration portion of the operative cycle for the register roll assemblies 43A and 43B thus utilizing the latter assemblies for advancement purposes only.
- FIG. 16 Another embodiment of the invention similar to that depicted in FIG. 16 includes the provision of photoelectric or other appropriate means to establish the length of a punch card being processed by detecting both the leading and trailing edge and in accordance generates signals to activate one or more of the register roll assemblies as may be required to effect the advancement and registration of a punch card of any we determined length from the feed roll 16 to the work station.
- the means needed to implement such recognition equipment including the logic required to generate the necessary control signals should be readily apparent to those having ordinary skill in the art.
- Another significant feature of the present invention concerns the control exercised over the pusher blade so as not to cause the card to overshoot its final registration position at the punching station. This could occur were the pusher blade permitted to impact too strongly against the idling punch card when the pusher blade comes forward and picks up the punch card at about 235 of revolution of the shaft 46 as shown in FIG. 5.
- the surface of the cam is specially configured (See FIGS. 17 and 18) such that as the pusher blade moves forward and across the center line defined by the center of the register roll shaft 46 and the pinch roll 52, the forward velocity oi the pusher blade is decreased theoretically to zero, but increases immediately thereafter as the blade picks up the trailing edge of the punch card. Thereafter, the for ward speed of the pusher blade reaches a maximum before again being reduced to zero at the final registration point.
- zero forward velocity of th: pusher blade is insured by introducing a dwell point on the cams surface from 230 to 240 as measured from start of rotation of the shaft 46 and another dwell point at 350 to 380 as measured from the start of revolution thereof.
- a power actuated punch card aligner which, as seen in FIGS. 1 and I5 comprises an arm 84 pivoted about pivot point 86 by means of a selectively actuated solenoid 88, the other end of the arm being provided with a substantial end section or shoe 90 adapted to move vertically into en gagement with the edge of the punch card 12 and urge it against a projecting horizontal stop edge 92 of the back plate 40.
- the power actuated punch card aligner also serves to insure lateral positioning of the punch card.
- FIG. 22 Another point to be made with respect to FIG. 22 is that in the aforementioned description of the subject invention it was mentioned that after the trailing edge of a punch card has dropped off the feed rolls 16 it is discretionary with the operator as to when the punch card is to be further advanced to the punching station; however, in the timing diagram of FIG. 22 there is but a single clock cycle indicated as elapsing between the time the card is dropped off of the feed roll I6 and the time of energization of the register roll assembly 43. Although it is possible to achieve this close sequence of operations it applies to situations in which the transfer of the punch card from the feed station to the punch station advances automatically without the intervention of the operator.
- an energize card aligner (ECA) signal is generated causing the power card aligncr of FIGS. 1 and to urge the punch card against the stop edge of the back plate 40.
- ECA card aligner
- the register roll assembly solenoid is energized by an energize register roll signal (ERR) which results in the movement of clutch pawl 82 so as to release the wrap spring clutch 80 thus initiating a single rotation of the register shaft 46.
- ERP register roll signal
- OPR a signal to prepare for the admission of the advancing punch card.
- the punch card does not advance by way of the register roll assembly for approximately the first 30 of rotation of the register roll because of the flat section 5011; however, some 20 after initiation of rotation the pusher blade 54 com mences its withdrawal movement preparatory to its later advance on the trailing edge of the punch card.
- the register roll 50 contacts the punch card and continues to advance the punch card through approximately two-thirds of that clock cycle until, as was noted with respect to FIG. 4, the punch card passes over the center line of the register rollpinch roll combination.
- FIG. 23 indicates the nature and duration of control signals used in the advancing and positioning of a 51 column punch card and differs from the similar representation for an column card only to reflect the fact that in handling the 51 column card two revolutions of the register roll shaft 46 are permitted in order to bring the trailing edge of the punch card into proper position to permit the pusher blade 54 to complete the final registration of the card at the punch station.
- each of the signals ECA, ERR, and CPR are extended an additional three clock cycles. Although the number of clock cycles permitted to effect the additional revolution will vary with the speed of rotation of the shaft 46 as imparted by the wrap spring clutch it is only necessary to permit sufficient time to complete the additional revolution of the shaft.
- a feed mechanism for quickly advancing and accurately positioning a punch card being fed from a first station through a visible station to a second station, said first station comprising a feed roll for feeding punch cards one at a time from said first station into said visible station, said visible station comprising a selectively actuated register roll assembly, said second station comprising indexing means operative to engage said punch card after said punch card has been released from said visible station whereby said punch card is brought into final registration with said indexing means, said register roll assembly positioned intermediate said feed roll and said indexing means, said register roll assembly comprising a pressure roll and a pusher blade synchronously driven with respect to said pressure roll, means operatively connected to said pressure roll assembly to selectively initiate the operation thereof, said register roll being so configured and operatively conditioned during the initial portion of each operative cycle such that a substantial portion or said punch card being advanced from said first station to said second station passes said register roll and remains stationary thereat prior to initiation of a cycle of operation of said register roll assembly.
- a feed mechanism for advancing a card from a supply station along a predefined path into a visible station and thereafter selectively releasing said punch card for advancement to a work station, said work station comprising means for accurately positioning said card, said visible station comprising a card drive roll adjacent said path, drive means for selectively rotating said card drive roll during an operating cycle, the outer periphery of said card drive roll having a portion configured to provide unrestricted clearance for a card during an initial portion of a feed cycle during which said drive means is not rotating said card drive roll, said card drive roll having another portion configured to advance the card along the feed path during a subsequent portion of a feed cycle during which said drive means is operative to rotate said card drive roll, a pusher blade mounted adjacent said card drive roll, said pusher blade being adapted to contact the trailing edge of said card during the terminal portion of a feed cycle, and means operable in synchronism with said card drive roll for advancing said pusher blade to move said card a final increment into accurate position at said work station during said terminal portion of said
- a feed mechanism constructed in accordance with the principles of claim 2 wherein said pusher blade is operatively connected to a cam, said cam having a surface comprising two dwell points, one of said dwell points imparting a near zero forward velocity component at the point in each operative cycle where said pusher blade comes into contact with the trailing edge of said card and the other of said dwell points imparting another near zero forward velocity component at the point in each operative cycle where registration of the card at said work station is complete.
