No. 256,171
Claims priority, application Germany, Feb. 5, 1962,
15 Claims. ((31. 271-71) Our invention relates to devices for conveying and stacking of card-shaped data carriers which arrive in a series arrangement and are to be stacked onto one another in a lay-off compartment, collecting box or the like.
In data processing equipment operating with punched cards or other card-shaped data carriers, there is the pro-blem of reliably placing such data carriers without damage into the layoff compartment despite the fact that the cards are being conveyed to the lay-off location at a high travelling speed. Simply decelerating the travelling cards shortly before they arrive at the lay-off location does not solve the problem. This is because, for highest operating speed of the equipment at a given conveying speed of the cards, the distance between successive cards must be kept small, but then the cards hit against the decelerated preceding cards thus causing damage to the cards, or clogging and other faulty operation.
It is an object of our invention to eliminate such difiiculties and to afford a high conveying speed of the data carriers as well as the desired reduction in speed shortly ahead of the lay-off location, without entailing the danger of trouble.
To this end, and in accordance'with a feature of our invention, we provide the conveying and stacking device for the data cards with deflecting means near the stacking location which deflect the end of a preceding card out of the plane of the next arriving card, and we further provide means for braking the preceding cards then to be issued from the device. As a result, each card just arriving in the stacking device will shoot over part of the preceding card into overlapping relation thereto. Thus the two cards greatly reduce the mutual spacing of their midpoints without disturbing each other, and the preceding card can freely leave the stacking device, for example to be dropped into a collecting container or compartment.
According to another feature of our invention, we provide for the above-mentioned braking of the issuing cards by operating the feed rollers for the arriving and the issuing cards at respectively different peripheral speeds, the peripheral speed for the issuing cards being smaller than that of the feed rollers that convey the arriving cards into the stacking device. In cases where the lay-off compartment for the cards is not to be located immediately behind the stack-forming device, it is anyhow necessary to equip the device with feed rollers for the issuing cards. For that reason it is particularly advantageous and results in a considerable simplification if the just-mentioned difference in feed-roller speeds is used for braking the travel speed of the cards.
According to another feature of our invention, the means for deflecting the cards consist essentially of two rotating deflector members, preferably blade wheels, arranged on opposite sides of the card travel path and having mutually opposed directions of rotation. The blade wheels pass with their radially projecting blades over or beneath the edge of the card issuing from the device and force its rear ends out of the plane of the next arriving card, so that the latter can shoot over or under the preceding card.
According to a preferred embodiment of the feature last mentioned, the rotational aXes of the blade wheels are inclined relative to a direction normal to the arriving cards or toward the direction of the leaving (issuing) cards. This permits arranging the active blade surfaces of the blade wheels in a plane perpendicular to the axis of rotation, thus avoiding undesired blowing effects which the blade wheels otherwise may have.
According to still another feature of our invention, the means for deflecting the cards comprise two stack-forming rollers whose respective axes extend substantially parallel to the lateral sides of the card travel path and which rotate in mutually opposed directions. The two rollers are pro vided with longitudinal slots extending along the peripheral surface and following each other around the periphery. Each arriving card runs into one of the slots of each roller and is then deflected by rotation of the rollers. Each subsequently arriving card enters into another slot of each roller. Since in such a device the cards are guided by the roller slots along a relatively large distance, the cards need not be particularly stiff for reliable performance.
The above-mentioned and more specific features of our invention will be apparent from the embodiments of card conveying and stacking devices according to the invention illustrated by way of example on the accompanying drawings in which:
FIG. 1 shows schematically and in perspective a device with an inclined guide surface for deflecting the cards.
FIG. 2 shows in a similar manner another device, equipped with two opposingly rotating blade wheels for deflecting the cards.
FIG. 3 is a diagrammatic and explanatory illustration corresponding in substance to a section along the line A-B in FIG. 2.
FIGS. 4 and 5 show in schematic perspective two further conveying and stacking devices with two opposingly rotating slot-ted rollers.
The same reference numerals are applied in all illustrations for respectively similar components. In all embodiments, the cards I arrive from the right at relatively high conveying speed. The cards leaving the device are denoted by 2. The arriving cards 1 are being forwarded into the device by a pair of feed rollers 3. The issuing cards 2 are conveyed out of the device and into a lay-off compartment (not shown) by means of another pair of feed rollers 4. The peripheral speed of the feed rollers 3 for the arriving cards 1 is three times as large as the speed of the feed rollers 4 for the leaving cards 2. As a result, the leaving cards 2 are so considerably declerated that, when the mutual spacing between the arriving cards is small, they are usually caught up by the next arriving cards 1. However, other braking means are also applicable. For example, the cards 2 may be pressed by one or more springs, for example leaf springs, against a surface, such as the supporting surface 5, so that their speed is braked frictionally.
In the embodiment shown in FIG. 1, the rear edge of the leaving card 2 is deflected out of the plane of the arriving card 1 by means of a sheet member 5 which forms an inclined plane. The arriving card 1 runs onto the inclined surface of member 5 and thus is deflected. That is, the leading edge of the card 1 in the illustrated embodiment is turned upwardly. As soon as the card 1 leaves the feed rollers 3 and enters between the feed rollers 4, its rear end turns downwardly due to the stiffness of the card. The card then is in the position of card 2, and the subsequent card 1 shoots beyond the rear edge of the preceding, braked card 2 into overlapping relation thereto. This takes place each time the distance of the next following card 1 is not so large that it no longer catches up with the preceding card 2.
The embodiment shown in FIG. 2 is equipped with blade wheels 6 for deflecting the .rear edge of the leading card away from the plane of the arriving card. The blade wheels 6 are provided with individual blades 7 or lugs which are arranged in a plane perpendicular to the rotational axes 8 of the respective blade wheels. The axes 8 are slightly inclined with respect to a direction normal to the arriving cards 1, or with respect to the direction of the leading cards 2 (FIG. 3) issuing from the device. Since the rotational axis 8 of each wheel 6 is normal to the surface plane of the blades 7, the blade wheels 6 do not operate as fans. Due to the rotation of the blade wheels 6 and the inclination of their rotational axes 8, the blades 7 pass over the leading card 2 and deflect it out of the plane of the arriving card 1. The peripheral speed of the blades 7 is preferably larger than the travel speed of the issuing cards 2.
The device shown in FIG. 4 is provided with slotted rollers 10 which operate as stack-forming as well as deflecting means. Each of the stacking rollers 10 has slots 11 extending along generatrix lines of the cylindrical periphery. The slots are uniformly distributed over the entire circumference. The rotational axes 12 of the rollers 10 are approximately parallel to the outer limit of the card-conveying path. The perpihery and arrangement of the rollers 10, particularly the distance between their respective axes, are such that the cards 1, 2 can be conveyed forward only along the slots 11. The rollers 10 rotate in mutually opposed direction as indicated by arrows 13. Each arriving card passes into one slot of each roller and is moved downward by rotation of the rollers. Each arriving card 1 enters into another slot 11, for example the next following or the second following slot, depending upon the distance between the cards on their conveying travel to the device. Thus, each card, while passing along the rollers, is simultaneously moved downwardly. The ridges 14 between the slots are rounded to facilitate entrance of the cards into the slots and prevent damaging the cards.
Aside from the illustrated means for deflecting the cards 2 out of the plane of the arriving cards 1, various other means are applicable, for example helical or worm gears mounted and rotating in the manner described above with reference to the blade wheels 6, in which case the rotational axis of the gears may or may not be inclined with respect to a direction perpendicular to the plane of the arriving cards 1.
It will be understood that a box or compartment for collecting the cards may be located immediately at the left of the illustrated device, so that the cards individually issuing from the device will drop into the compartment where the desired stack is formed from the cards successively arriving in the device.
FIG. shows a particularly advantageous embodiment of the latter type in which the braking means are combined with the stack-forming rollers. Since the device partly corresponds to that of FIG. 4, only the differences need be described.
Mounted on each roller at the end of each longitudinal slot 11 is a V-shaped pair of leaf springs. The springs of each pair have one end substantially flush with the respective lateral walls of the slot. The other spring ends in each pair press against each other. When the card shoots into a slot, it runs between the two springs of the pair and forces them apart, thus being subjected to frictional braking. Such a device has the advantage that successive cards do not mutually engage at all as long as they travel at appreciable speed or if the speeds of successively arriving cards are appreciably different from each other. This fully eliminates any danger of damage to the card edges or punched holes, and the spacing between successively arriving cards can be given any desired amount.
The portion of each roller that carries the leaf spring 15 may be integral with the roller body or may be produced as a separate structural part.
Since the decelerating travel of the cards may have different lengths, due to inevitable tolerances of the respective cards, the device is further provided with a slowly rotating roller 17 upon which the cards Will drop after they are decelerated and downwardly ejected from the slotted rollers 10. The roller 17 then pushes the cards forward until they hit against the front wall 19 of the layoff magazine. The distance between the axis of roller 17 and the front wall 19 of the magazine is made equal to one card length plus one-half the diameter of the roller 17, and the distance of the magazine front wall 19 from the exit edge of the leaf springs 15 on the slotted rollers 10 is at least equal to the maximal braking travel distance of the cards 1.
In order to secure a satisfactory ejection of the decelerated cards from the stacking rollers 10, and to prevent edging of the cards about their longitudinal axes due to non-simultaneous release of the cards from the leaf springs 15, the device is further provided with an inclined guide. wall or sheet 16 spaced forward from the stacking rollers and located approximately at the height of their axes. The front edge of each arriving card 1, after passing beyond the leaf springs 15, hits against the inclined surface of the guide wall 16 and is thereby deflected downwardly so that it enters between the side walls 18 of the lay-off magazine before the rear end of the card is released from the stacking rollers 10. Such an arrangement is also of advantage in conjunction with the preceding embodiments, if it is desired to prevent edging or inclination of cards as they are stacked between lateral surfaces.
In embodiments of the type shown in FIGS. 4 and 5, the slots 11 of the stacking rollers 10 may also be given an arrangement that is not accurately parallel to the roller axes but is slightly askew, for example helical, in such a manner that the front end of each slot 11, or the leaf spring pair 15 in FIG. 5, will travel at the angular speed of the roller 10 just such a distance that a card shooting into the slot is guided on its entire slot path in parallel relation to the axes of the stacking rollers 10 and preferably at the height of these axes. This affords the assurance that each card 1 is held on both sides along the full axial length of the ridges 14, up to the leaf springs 15 in the embodiment of FIG. 5. For the same purpose the rollers 10 may be given a somewhat conical shape with the slots 11 extending parallel to generatrix lines.
Upon a study of this disclosure it will be obvious to those skilled in the art that various modifications are applicable and that the invention can be given embodiments other than particularly illustrated and described herein, without departing from the essential features of our invention and within the scope of the claims annexed hereto.
