The paternoster-like storage and conveyor consists of two parallel, continuous horizontally and vertically staggered endless chains 1 and 2, which run over sprockets 3,4, 5 and 6, wherein the sprockets 5 and 6 are formed as Doppelkettenradpaare to the required synchronous running to reach the endless chains 1 and 2. At the endless chains 1 and 2 struts 7 are fixedly arranged at a fixed distance.

A rigid right angle formed support arm 8 connects the struts 7 of the endless chains 1 and 2, which have the same position on the respective endless chain such that the support arm 8 is pivotally connected to the outer end of the strut 7 of the endless chain 1 and a leg of the support arm 8 is movably mounted in the end of the strut 7 of the endless chain 2. At this leg of the support arm 8, the tray 9 is fixed. As a result, the tray 9 is constantly held in a horizontal position during continuous operation, wherein a stabilization of the tray position is achieved by the chain guide, not shown.

This revolving operation is accomplished by a stepper drive, which consists of a working cylinder 10, on the piston rod, a folding mechanism 11 is arranged in duplicate, which acts on the strut 7 by the stroke χ during extension of the piston rod of the working cylinder. Thereafter, the next tray 9 has arrived in the unloading position with the guide 12. The piston rod of the working cylinder 10 is withdrawn. The angles of the Klappmerhanismus 11 fold back when hitting a strut 7 and move after overcoming the strut 7 by Eigenge / icht back to their original position.

In the unloading position, the storage and conveyor is locked. ¹ means for this are arranged on the guide 12 working cylinder 16 with attached to its piston rod prism 17 and the prism receptacle 18 which is arranged on the tray 9. Diuse device is necessary so that a safe transfer of prismatic objects from the tray 9 can be done in the guide 12, ie it should always be the same level between tray 9 and guide 12 guaranteed.

In the unloading, if necessary, the subsequent device, for. As packaging machine, the automatic discharge of the prismatic object located on the tray 9, which in our embodiment, an empty carton

The discharge takes place by means of execution cylinder 13, which acts with its piston rod on a pivoting about the pivot point Ki angle lever '.Ξ and pushes the empty carton in the guide 12.

This process is repeated until all shelves 9 are emptied. After this, then again a complete occupancy of all trays 9 with empty carton by hand, since the trays 9 are all accessible from one side.

For this 2 pages drawings Field of application of the invention The invention relates to a paternoster-like storage and Fordereinrichtung for prismatic objects, in particular for cardboard packaging machines. Characteristic of the known state of the art It is well known that the storage and feeding of blank cartons is realized by means of horizontal feed belts equipped with stepper motors, i. H. the larger the stockpiling of blank cartons, the longer the feed belt. A disadvantage of this device is the high space requirement and the use of stepper motors, which are complex both in the purchase, as well as in maintenance. Conceivable is the use of circulation conveyors, which are designed according to the paternoster principle. Generally, these circulation conveyors consist of two vertically circulating endless chains and of a plurality of trays, which are attached to the two endless chains at predetermined equal intervals pivotally. Other units such as drive motor, transmission and control are arranged. A paternoster-like circulation conveyor with the above-mentioned elements was found, wherein guide members are arranged on the end walls of the shelves, which are guided on both sides in stationary endless guide rails. Due to the special design and arrangement of the guide members and guide rails, the paternoster principle is achieved, d. H. the trays remain in the reversal points of the vertically rotating endless chains in the horizontal plane (DE-PS 3302018, B65G, 1/12). A disadvantage of this type of circulating conveyor is, on the one hand, that they can only be loaded and unloaded at one side and usually there at a predetermined location and, on the other hand, their high outlay on material, for the drive and the high degree of complexity of the circulating conveyor itself, in particular As far as the technical means for the loading process of the paternoster principle are concerned. Furthermore, these circulation conveyors are only hand-loaded and unloaded or it must be a relatively high cost for a loading and unloading operated. Object of the invention The aim of the invention is to provide a patornosterartige storage and conveyor, by means of which a minimization of the space requirement is made possible with relatively high storage of prismatic objects in order to favor the installation in existing building fabric. It should also be achieved that the storage and conveyor is designed cheaper and easier in their execution, d. H. Reduction of the cost of material and for the drive and that ultimately improves the working and living conditions of the operator.
