Claims priority, application Germany, Feb. 24, 1964,

Claims. (Cl. 27171) My invention relates to devices for conveying and .stacking of card-shaped data carriers which arrive in a sequence 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 problem of reliably placing such data carriers without damage into the lay-off compartment despite the fact that the cards are being conveyed to the lay-ofif location at a high travelling speed. Simply decelerating the travelling cards shortly before they arrive at the lay-ofl 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 the 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.

To avoid such trouble, it has become known from US. Patent No. 3,223,409, to E. Eissfeld et al., to pro vide a conveying and stacking device for data cards with means for deflecting the cards out of the plane of arrival onto the stack or lay-off location, these deflecting means comprising 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 provided with longitudinal slots extending along the peripheral surfaces and following each other around the periphery. Each arriving card runs into one of the slots of each roller and is then deflected downward by rotation of the two rollers. Each subsequently arriving card enters into another slot of each roller. In this manner the cards are reliably stacked without the danger that the leading edge 7 of the card may abut against the rear edge of the preceding card. In a preferred embodiment of this device, each slot is provided with braking means for decelerating the cards as they pass through the stacking rollers. The walls of the slots run slightly askew, for example helically, so that a card shooting into a slot is guided on its entire s-lot path in parallel relation to the axes of the stacking rollers and substantially at the height of these axes, thus affording the assurance that each card is held on both sides along the full axial length of the slots.

The present invention more particularly relates to a stack-forming card-conveying device of the latter type and has for its main object to improve such devices so as to afford the possibility of varying and adjusting the helical pitch or inclination of the slot walls on the stacking rollers for adaptation to a particular card travel speed and/or to the rotating speed of the stacking rollers.

Another object of my invention, relating to stack-forming conveying devices of the above-mentioned type, is to simplify and improve the manufacture of the stacking rollers and to secure a more reliable frictional braking action for decelerating the cards as they reach the end of their travel in the slots of the stacking rollers.

To achieve these objects, and in accordance with one of the features of my invention, I provide each of the two parallel stacking rollers of the card conveying device with an axially elongated roller body and with a number of elongated bars which extend lengthwise of the body so as nited States Patent 0 to form respective lateral walls of the above-mentioned guide slots, each bar having an elastically yieldable portion of the rear end relative to the card travel direction; and the rear end portions of peripherally adjacent bars extend toward each other and thereby form a card-decelerating friction brake. Furthermore, each bar is fastened to the roller body at only two localities, namely at the front end and the above-mentioned rear end portion respectively.

The above-mentioned and further objects, advantages and features of my invention, said features being set forth with particularity in the claims annexed hereto, will be apparent from, and will be described in, the following with reference to embodiments of devices according to the invention illustrated by way of example on the accompanying drawings, in which:

FIG. 1 is a perspective view of a card-stacking conveyor device, shown partly schematically.

FIG. 2 is an axial section of a stacking roller; and FIG. 2a shows a perspective view of a detail corresponding to FIG. 2.

FIG. 3 is an exploded perspective view of a different, partially illustrated stacking roller; and

FIG. 4 is an axial section of the stacking roller according to FIG. 3.

The device shown in FIG. 1 corresponds to the one illustrated in FIG. 5 of the above-mentioned patent (Serial No. 256,171); and it appears helpful to first describe this device, since devices according to the invention may have fundamentally the same design and performance with the exception of the features relating to the appertaining two stacking rollers which are to be modified as exemplified by the embodiments shown in FIGS. 2, 2a and FIGS. 3, 4 respectively.

- Referring to FIG. 1, the data card 1 arrives from the right at relatively high conveying speed, being driven by a pair of pinch rollers 3 rotating at the peripheral speed It so as to enter between two stacking rollers 10 whose respective axes are parallel to each other and to the card travel path. At the arrival moment of the card 1, two of the longitudinal slots of the respective rollers 10 are located opposite each other and are engaged by the respective longitudinal edges of the travelling card 1. Braking means at the ends of the slots 11, consisting of pairs of leaf springs 15 pressing against each other, decelerate the cards as they enter between the leaf springs. The two stacking rollers 10 rotate in mutually opposed directions and displace the card 1 downwardly as soon as it has entered into the respective slots. The card then drops out of the slots into a lay-off magazine. To secure a satisfactory release of the decelerated cards from the stacking rollers 10 and to prevent edging of the cards due to non-simultaneous release of the cards from the leaf springs 15, the device is provided with an inclined guide 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 hits against the inclined guide sheet .16 and is thereby deflected downwardly so that it enters between the side Walls 18 of the magazine before the rear end of the card is released from the stacking rollers 10. For obtaining a properly aligned stack of cards, the device is provided with another driven roller 17 which, when the released card drops upon it, drives the card forward until the front edge of the card abuts against the front 'wall 19 of the magazine.

According to the embodiment of the invention exemplified in FIGS. 2 and 20, each stacking roller 10 (FIG. 1) comprises a tubular roller body 20 which is closed by a massive disc 21 at its front end, this being the axial end at which the card first arrives. The roller body is concentrically mounted on a drive shaft 22. The front disc 21 of the roller has on the card-entering side an annular groove 23 concentric to the axis of the shaft 22. The roller is further provided with a number of bars consisting for example of spring steel. These bars form respective lateral walls of the above-mentioned card-guiding grooves 11. As shown in FIG. 2, the front portion of each bar 24 is curved to a U-shaped configuration. The shorter U-leg forms the front end of the entire bar and is inserted into the above-mentioned annular recess 23 and fastened therein by a casting consisting, for example, of solder or cementing material.

The bars 24 extend on edge along the outer periphery of the rotor body so as to form the slots 11 between each other. Along the major portion of its length, each bar has an elongated, rectangular cross section standing on edge; that is, the longitudinal dimension of the cross section extends radially with respect to the roller body. At the rear end, the upright cross section merges gradually with a broad and flat cross section. The flat rear ends of the bars are elastically in contact with each other in a peripheral succession concentric to the axis of the rotor body. As long as no card enters between two adjacent rear ends, these ends will touch or substantially touch each other, but a travelling card will force the ends apart and thus be subjected to braking friction. To stabilize the localities of the fiat rear ends 24a, particularly with respect to excessive tangential displacements, the tubular body 20 of the roller is provided with pins 25 at a few angularly spaced localities. The pins 25 protrude in the radially outward direction and pass through respective bores 26 in the broad and flat rear ends of the respective bars 24. The bores 26 have a larger diameter than the pins to provide for some clearance.

The bars 24 preferably consist of a single integral body inclusive of their front and rear ends. The material of the bars is sufficiently elastic and is so pretensioned that the bars have the tendency to place themselves radially against the tubular body 20 of the roller. As a result, the rear ends of the bars 24 normally will touch each other in a peripheral succession, and at each point of engagement there obtains an elastical force in the tangential direction. This force is available as frictional force for decelerating a card penetrating between the two adjacent rear ends 24a.

By selecting the angular position of the tubular body 20 relative to the disc 21, the bars 24 can be given a desired inclined position along a helical line. The tubular body 20 and the disc 21 are then to be fixed to each other in the selected angular relationship, for example by means of a set screw (not shown) passing radially through the wall of the tubular body 20 into the disc 21. The angular position corresponding to a desired slight helical pitch may be adjusted by the manufacturer in accordance with particular data processing equipment with which the card conveying and stacking device is to be used, this position to be then permanently preserved by rigidly joining the tubular body 20 and the disc 21 together. However, the angular position may also remain adjustable to permit changes in an angular setting during use of the conveying device, for example in conjunction with changes in processing or conveying speed.

The embodiment of the stacking rollers shown in FIGS. 3 and 4 is provided with bars 27 individually cut and bent from sheet metal and joined with separately cut and shaped rear end portions 28, also consisting of sheet metal. The tubular body 29 of the stacking roller is subdivided so as to comprise a separate rear portion 30 for accommodating the rear-end portions 28 of the longitudinal bars 27. The bars 27 constitute jointly the longitudinal guide slots of the stacking roller. Each bar 27 has a U-shaped cross section open toward the roller body. The forward end of each sheet-metal bar, this being the end where the card first arrives, is curved to an inwardly extending shape so as to form a hook-like extension 31 which is hung over the edge of the tubular body 29 and abuts against 4 a disc 32' resting against an inner peripheral shoulder of the tubular rotor body 29.

The end portions 28, made of spring metal, are stuck into the rear ends of the bars 27 (FIG. 3a) so that the bars and the end portions 28 lie flush with each other at the junction location to secure a smooth travel of the cards. The end portions 28 are likewise provided with a hook-shaped extension 32 with which they are hung over the edge of the annular body 30 and abut against an inner peripheral shoulder thereof.

The tubular body 29 and the annular body 30 of the stacking rotor are fastened on the roller shaft 22 by means of the above-mentioned disc 32 and another terminal disc 33. Respective further discs 34 and 35 are tightened by bolts against the respective discs 32' and 33, thus clamping the hook-shaped extensions of bars 27 and end portions 28, these extensions having a conical or wedge-like shape, against the respective bodies 29 and 30. This is apparent from the section shown in FIG. 3.

The hook-shaped extensions 31 have respective lateral lugs 36 (FIG. 3) which serve as spacers to secure the correct distance from the adjacent bar. Analogously, the proper distance between the resilient end portions 28 is secured by having them pairwise interconnected through a bridging member 37, each bridge extending over one bar division on the side of the hook 32 facing the rotor axls.

By changing the angular position of the ring-shaped body 30 relative to the tubular body 29, the bars 27 can be given the desired helical pitch in order to utilize the entire height of the bars 27 for guiding the card edges and utilizing the entire elastic width of the end portions 28 for decelerating the cards. The adjusting and fixing of the angular position is effected in the manner already described with reference to FIGS. 2 and 2a.

To those skilled in the art it will be obvious upon a study of this disclosure that my invention permits of various modifications and may be given embodiments other than particularly illustrated and described herein, without departing from the essential features of the invention and within the scope of the claims annexed hereto.
