Definitions

  • the cards are fed past analyzing devices, which analyze the controlling index marks of the cards (for instance holes), and which control accumulators or printing mechanisms according to the result of the analysis.
  • the analysis may, however, also be effected merely for the purpose of comparing the perforations of different cards, or a punching means may be arranged in the card feeding path, subsequently providing the controlling cards with a perforation.
  • cards are mechanically advanced from two different magazines, said cards either having to be deposited in two separate receiving pockets or having to be interpolated according to certain points of view and in accordance with the result of the comparing analysis, and which then have to be deposited into a single common pocket, designated as the interpolating pocket.
  • Such a machine is for instance known as a card interpolator.
  • the invention provides in the card feeding path a card turning device adapted to turn the cards in the card feeding plane through any desired angle. Thereby it becomes possible, for instance in machines serving for interpolating tasks, to arrange each of the two magazines on any of the two sides of the interpolating pocket and still to comply with the just mentioned condition of the simultaneous analysis of corresponding hole positions of the cards advancing from the two magazines but nevertheless to deposit all cards in the interpolating pocket in the same relative position.
  • the magazines may be provided on both sides of the interpolating pocket in such way that all the card pockets as well as their feeding devices are arranged in a straight line which results in a very pleasant appearance of the machine.
  • the cards When applying the invention the cards may be deposited in the two magazines in such manner that the upper card edge advances in .the feeding direction, so that always 2,873,114 Patented Feb. 10, 1959 ICC identical hole positions of the cards of the two groups of cards may be analyzed by the analyzing means.
  • the one card arrives under the card turner which will turn the same in the card plane through the desired angle without reversing it, and which will then again transfer the card to the feeding device, the latter feeding the card to the receiving pocket. After this turning movement, the card will be in the receiving pocket in the same position as the cards arriving from the other magazine so that, for instance, the usually cut off corners of all cards are in alinement.
  • the invention does not only permit a constructively favorable arrangement of the supplying and analyzing means as well as an easy accessibility of the same but contrarily to the known devices it permits also to construct identical supplying devices for the two card stacks and the analyzing devices, thereby reducing the manufacturing costs of the machine.
  • the magazines can be arranged by any desired angle with regard to the receiving pocket so that, for instance, the magazines and their feeding path may be arranged at a right angle with regard to the receiving pocket and notwithstandnig the cards may be deposited in the same position relative to each other.
  • the card turning device consists of two pairs of feeding rollers rotating in opposite direction and being equally spaced from the feeding centre line, said rollers engaging the card as soon as the centre of the same arrives at the centre of the turning device.
  • the rotating rollers are operatively so connected to the rollers which feed the card to the rotating rollers and remove it from the same, that the rotating rollers engage the card shortly before the supplying rollers are raised from the card and the removing rollers re-engage the card before it is released from the rotating rollers.
  • FIG. 1 For instance, turning disks which are pressed against each other as soon as the card is between them may be provided instead of the first mentioned rotating rollers or of the gripper, said disks imparting then to the card the rocking movement and afterwards supplying it again to the removing rollers.
  • a deflector may be provided in the card feeding path ahead of the card turning device, said deflector deflecting the card from the card feeding path before it is supplied to the card turner and feeding it to a special receiving pocket.
  • the card may be selectively deposited into a special receiving pocket without receiving a turn, or be turned and then fed into the interpolating pocket.
  • the inventive device is particularly advantageous where cards are fed in opposite directions from two different magazines and where cards are to be deposited in a common pocket in the same relative position.
  • the application of the invention is, however, not restricted to such machines.
  • the invention may rather be applied wherever it is necessary for any reasons to deposit the cards in a position other than the one they had when being removed from the magazine.
  • Fig. 1 shows diagrammatically a machine in which cards are removed from the various magazines, said cards may then be deposited either commonly in an interpolating pocket or also separately.
  • Fig. 2 shows diagrammatically the position of the cards supplied to the interpolating pocket from opposite sides as well as the arrangement of the card turner.
  • Fig. 3 shows in plan the card turner which is arranged in the card path.
  • Fig. 4 shows the rear wall of the card turner with the drive of the latter.
  • Fig. 5 shows the front side of the card turner with the receiving pocket and the interpolating pocket.
  • Fig. 6 shows a side view from which particularly may be seen the arrangement of the turning rollers.
  • Fig. 7 shows in a perspective illustration an embodiment with a card turner provided as gripper.
  • Fig. 8 shows in a perspective illustration a further embodiment in which the card turner consists of two rotating disks.
  • the machine diagrammatically shown in Fig. 1, is a card interpolator in which the cards from the magazine 10 shall be interpolated between the cards from the magazine 11.
  • the cards from the two magazines are fed in a known manner by feeding means past analyzing brushes and are compared with each other. The comparison is herein of no importance.
  • the deposition of associated cards is elfected in the interpolating pocket 12.
  • the diagram of the supply of the cards may be seen from Fig. 2.
  • the cards advancing from the magazine 11 run ahead with the upper edge of the card and are deposited in the same position in the interpolating pocket 12 which is only diagrammatically indicated in Fig. 2, so that, accordingly, their cut off corners point down to the left.
  • the cards from the magazine 10 must now also be fed ahead with the cut off corners so that the analyzing brushes may always analyze the same hole positions of the cards advancing from the two magazines.
  • the preferred embodiment illustrated in Figs. 3 to 6, uses two pairs of rollers arranged symmetrically to the centre line of the card feeding path. As soon as the card is engaged by said two pairs of rollers, they impart to the card a turning or rocking movement through 180 since the pairs of rollers rotate in opposite directions relatively to each other. The card is fed to the removing rollers after the 180 rotation.
  • the card turning device according to Figs. 3 to 6, is constructed in detail as follows and operates as will now be described:
  • the card is supplied by means of the feed rollers provided upon the shaft 14 (Fig. 3) to the turning device and is fed so far until the front edge of the card has passed between the faster running rollers 16.
  • rollers 16 engage the card and feed the same under the pairs of turning rollers 17 and 18.
  • the higher speed of the rollers 16 with regard to the feed rollers 15 has been provided in order to obtain a sufficiently large distance from the following card and in order to prevent a relative disturbing of the cards during the turning movement. Accordingly, the rollers 16 feed the card between the pairs of turning rollers 17 and 18, and in such way that the centre of the card is under the rollers, as may be seen from Fig. 3.
  • the turning device is driven through the belt disk 19 which is rigidly connected to the toothed sectors 21 and 22 (Figs. 4 and 6) and mounted together with the same upon the stud 30.
  • the toothed sector 21 drives by means of the toothed wheels 23 and 26 the rollers 16 upon the shafts 24.
  • the drive of the two turning rollers 17 is effected by the toothed sector 22 which drives the toothed wheel 27, rigidly provided upon the shaft 25.
  • the toothed wheel 28, also fast upon the shaft 25, is engaging the toothed wheel 29 upon the shaft 31.
  • the two shafts 25 and 31 carry in addition the one pair of turning rollers 18.
  • On the front side of the turning device there is provided an idle gear 33 mounted on an angle 32 (Figs.
  • a lifting device is provided so that alternately the feeding rollers and then the turning rollers act on the card.
  • the reverse control is effected by a slide 41 (Figs. 4 and 5) provided with inclined planes and adapted for recipro eating movement in the guiding pieces 42 and 43.
  • a lever 45 which is fast upon the shaft 44 is controlled by a cam 46, said cam being connected to the belt disk 19, synchronously with the card feed.
  • a lever 47 which transfers the movement to the front slide 48 carrying a stud 49 slidably guided in an elongated hole 51 of the lever 47.
  • Lever 45 has a corresponding stud, not shown, engaging a corresponding slot (not shown) in slide 41 so that slide 41 is moved by the lever 45.
  • the two levers are drawn by the springs 52 to the right of Fig. 4 and to the left of Fig. 5, respectively, until the lever 45 engages the cam disk 46.
  • the two slides are herein carried along in accordance with the cam position.
  • the shaft 31 is somewhat lifted in the position shown in Fig. 4 and therewith are also lifted the upper turning rollers 17 and 18. In this position the slide has no influence upon the two shafts 24 with the rollers 16 so that the rollers 16 are pressed against the card under spring action and then feed the card.
  • the cam 46 will move the lever 45 and the latter will move the slide 41 to the left (Fig. 4) while the lever 47 moves the slide 48 to the right (Fig. 5).
  • the inclined guide faces of the two slides are arranged in such way that during movement to the left or to the right, respectively, first the turning rollers 17 and 18 will engage the card whereupon shafts 24, and therewith the rollers 16 are raised. Now, the turning rollers will act upon the card while the rollers 16 are raised. This position is shown in Figs. 5 and 6.
  • the sector 21 and the retating rollers 17, 18 are dimensioned in such way that the card rotates exactly for the cam 46 permits the lever 45 to rock to the right (Fig. 4) under the inv the lead necessary for the turning movement.
  • a deflector 53 (Fig. 5) is rocked in clockwise direction about the shaft 54 so that the cards are not supplied to the rollers 16 but to the receiving pocket 13.
  • This deflector may of course be put in a known manner under the control of the comparing device so that depending on the comparison the cards may be deposited selectively into any one of the two depositing pockets.
  • FIG. 7 A further embodiment is shown in Fig. 7.
  • the card is supplied to the rollers 61, as it is indicated by the arrow. As in the above described embodiment these rollers run faster than the regular feed rollers, in order to obtain
  • the lower rollers 61 are seated upon a shaft mounted in the sidewalls while the upper rollers 61 are seated in a shaft mounted in the two levers 62.
  • the levers 62 are mounted upon the shaft 63.
  • the card is moved upon the base plate 64 of a gripper by means of the rollers 61.
  • the upper rollers 61 are lifted by means of the cams 66 and the levers 62.
  • the cams rotate synchronously with the card movement.
  • the crank 67 rotates also synchronously with the card movement and imparts to the arm 68 upon the shaft 71 a rocking movement through the link 69.
  • On the shaft 71 is further provided an arm 72 upon which is mounted the sleeve 73.
  • the latter carries on its upper end the gripper 64.
  • the slightly resilient metal sheet 65 slides off the stop bar 77 and presses the card against the plate 64 of the gripper. Accordingly, the card is taken along and is thereby simultaneously turned through 180.
  • the gripper moves the card between the rollers 78 and rollers 79 which are disengaged at this moment.
  • the shaft 81 with the rollers 78 is mounted in the two levers 62.
  • Fig. 8 shows a third embodiment.
  • the card is moved between the rollers 86 and 87 in the direction of the arrow and is engaged by the same and fed between the Shaft 92 is movable with levers 91, and theshaft which carries rollers 87 is mounted on a stationary support.
  • Levers 91 are pivotally 6 mounted in the machine frame by pins 98.
  • the cam disks permit the stirrup 97 to move the levers 91 upwardly under the action of springs 96.
  • Shaft 92 with the rollers 86, and a shaft 93 with the rollers 94 are mounted on levers 91, and stop 99 prevents further advancing of the card.
  • the stirrup 97 raises the axially movable rotary disk 89 through shaft 101 so that the card is held between the two rotating disks 88 and 89.
  • the lower rotating disk is rotatably mounted upon shaft 101.
  • the toothed section 102 which reciprocates once per card cycle will engage the toothed wheel 103 whose radius is chosen in such way that the toothed wheel 103 performs during one full reciprocation of the toothed sector 102 half a revolution in counter-clockwise direction and then half a revolution in clockwise direction.
  • the shaft of gears 103, 104 is turnably mounted on the machine frame.
  • This movement is transferred through a pair of bevel gears 104, 105 to the upper rotating disk 88.
  • the rotating disks turn in the feeding path and turn the card in clockwise direction. Thereby the card is moved between the rollers 94 and 106. Rollers 94 are raised at this time. Rollers 106 are turnable with a shaft which is mounted in a stationary supporting part of the machine.
  • the cam disks 95 effect downward movementof shaft 93 with the rollers 94 by means of levers 91, whereupon the card is gripped by the rollers 94 and rollers 106, and since at the same moment the card is released by the rotating disks it is fed by the rollers 94 and 106 to the receiving pocket.
  • the upper rotating disk 88 returns again to its normal position and the cycle may begin anew.
  • the inventive idea can be carried into practice in various manners. It can also be readily realized that the invention may be adapted to any desired turning angle since for this purpose it is only necessary to provide the ratio between the card turner and its drive accordingly, and to position the axes of the removing rollers in such Way that they are in parallel with the leading card edge after the turn of the card.
