Definitions
- This invention relates toy a high speed card punch for use in making cards for business machines such ⁇ as sorters and collators, and, in particular, to a high speed punch for use in making business machine cards whe-rein the car-d is intermittently driven, whereas, the driving means is continuously rotating at a constant velocity.
- IMost punches in use today provide a stationary punch and die with intermittently rotating feed rolls for intermittently feeding the card through the punch station. As the card progresses through the punch station, it is intermittently driven so that the cards can be punched during the dwell or stopped position.
- the intermittent motion is either provided by a Geneva cam or other mechanism or variable speed motors, commonly called stepping motors, to accelerate and decelerate the feed rolls so that the card is intermittently driven through the punch station. In such a device the punching occurs at the punch station when the card is at zero velocity.
- 'It is another object of this invention to provide a card feeding device wherein one or more portions of the card may be at zero velocity, Whereas the other portion of the card is continually moving, this being accomplished by changing the path of the card.
- cards are shown at 10 which are adapted to be fed by a plurality of pairs of feed rolls 12.
- the cards here are intended to be those which are generally used in business machines and could also include tape as well as sheets.
- the feed rolls 412 drive the card past a punch station generally designated as 14.
- the punch station includes a number of punches which can be mounted in parallel, only one of which is shown for purposes of this invention.
- the punch station comprises a punch 16 slidably mounted in a punch guide block 1S and a punching die 20 provided with an opening 22 to receive the punch 16.
- a driving member or link 24 adapted to engage the end of the punch 16.
- the drive link 24 is pivotally mount-V Normally, the drive link 24 oscillates about pivot 26 ⁇ without driving the punch 16 into the die 20.
- an interposer 27 is connected -to an armature 29 which is adapted to be energized at the appropriate time by a magnet 31. This time for perfor ⁇ ation is synchronized with the rest of the machine so that the punch perforates the ca-rd while it is motionless.
- Sensing brushes (not shown) or the like are generally used to sense a signal in a master card, which signal represents information to be punched into the card.
- the signal operates the magnet 31 in synchronization with the rest of the machine when it is time to punch.
- vIn iorder to drive the cam 30 in synchronization with the feed rolls 12, the cam is mounted on a pulley or thelike 34 and connected to the shaft 36 on which 4the feed rolls 13 are mounted, through a chain link or drive belt 38.
- the cards l0 which as noted previously could also be a continuous tape or sheet, are fed through the punch station 14, by the feed rolls 12 and carried away by the feed rolls 13.
- the path for the card is defined by xed guides 40 and 42 for entrance into the punch station and fixed guides 44 for the exit out of the punch station.
- a continuously changing feed path for the cards is controlled by suitably shaped cams 46, 48, 50 and 52. These cams rotate synchronously with feed rolls l2 and 13 in timed relation with the entire punching mechanism so that when the card changes its path from one position to another, it can be punched at the punching station when the card comes to rest.
- the synchronization can be accomplished by providing an idler gear 55 for driving the cam 52.
- Such a gearing arrangement can be duplicated with the other cams.
- the card path length is lessrthan the card path shown in the position at 56, whereas the length of the card path is greater at the fixed guide 44 as shown at 55 than when the card is in the position shown by the dotted line at 57.
- a complementary cam 58 may be used for this purpose. Also, if the card has a tendency to move while at the punch station during the interval that the card is changing card paths, a brake means could be used for intermittently holding the card at the punch station.
- the card path will not begin to change until the point 60 on the cams begins to move away from the card and the point 62 begins to push on the card when it is in position 56 and 57. In the embodiment shown, this leaves about 60 of a 360 revolution for the card to change card paths. This also is the period when the card is stationary at the punch station ready for punching. This occurs twice during one revolution of the cams and feed rolls. However, if more cam surfaces were used, the card would be stationary more times per revolution.
- the portion of the card at the punch station 14 remains at zero velocity.
- the punching of information into the card may be accomplished during this stationary period at the punch station by actuating the punch element 16.
- the punch element can be retracted out of the punch die by a spring or suitable mechanism (not shown).
- the ability to maintain motionless that portion of the card at the punch station when the feed rolls 12 are feeding the card is made possible by the lengthening of the card path from that at 54 to that at 56, while during the same period of time the action of feed rolls 13 is delivering the card is made possible without disturbing the stationary portion by the shortening of the card path from that at 55 to that at 57.
- the cards may be constantly under the control of cams 46, 48, 50 and 52 and complementary cam 58 which bears on the opposite face of the card.
- This cam can be of the same shape as cams 46 and 48 and be operated in timed relation with them.
- other guide means or braking means can be used at the punch station.
- a plurality of card punching and feeding devices may be disposed adjacently on a single machine for this purpose.
- a marking member at la marking station and movable into contact with a form to mark the form guide means including oppositely arranged fixed portions and movable por-tions through which the form moves to the station, means near the entry end of lthe guide means for advancing a form at a constant lineal speed toward the station, and mans operative independently of the form for withdrawing the movable portions away from ythe xed portions, said advancing means being effective as the movable portions withdraw to cause the form to follow a lengthened path to the station, such withdrawal being suicient to cause the velocity of the particular part of the form at said station to be reduced substantially to zero While the advancing means is moving a rearward part of the form at said constant speed, the movement of the withdrawing means being coordinated with that of the marking member to cause the part of the form which is to be marked to be substantially at zero velocity just before and during the time it is contacted by the marking member.
- a marking member at a marking station and movable into contact with a form to mark the form guide means including oppositely arranged xed portions and ⁇ movable portions through which the form moves to and from the station, means near the respective ends of the guide means for advancing a form at a certain constant lineal speed toward the station and ⁇ at the same speed away from the station, and means operative independently of the form for withdrawing the movable portions away from the xed portions to concurrently lengthen the path traversed by the Aform in approaching the station and shorten the path it traverses beyond the station by amounts sufficient to cause the velocity of the particular part of the form at said station to be reduced to zero while at least one other part of the form is moving at said constant speed, the movement of the withdrawing means being coordinated with that of the marking member to cause the part of the form to be marked to be substantially at zero velocity just before and during the time it is contacted by the marking member.
- Form marking apparatus comprising a marking station; guide means including generally S-shaped convex and concave stationary guide surfaces at opposite sides of the station, and constantly rotating cams having portions movable toward ⁇ and away from said surfaces to vary the lengths of the lfeed paths followed by the form; just before and during the time it is contacted by the means near respective ends of the guide means for ⁇ advanemarking member.
