The invention relates to a device for conveying of chocolate bars or bars that come in uninterrupted sequence from a bar or cooling device emerge side by side in successive rows transversely to the conveying direction and be fed to a stacking or further processing point, using one of the successive Rows of panels on the main conveyor carrying trays and of distribution elements for transferring the Rows of panels from the main conveyor to several cross conveyors running over the main conveyor, wherein the trays with the chocolate bars lying thereon are individually gripped and via the cross conveyor be guided. Such a device is protected by earlier patent 1199,692. The proposed Arranging one lifting device for each cross conveyor increases the technical effort the entire system, especially if several processing points from the main conveyor, such as chocolate bar packing machines, which have to be loaded independently of each other work, i.e. according to their respective packing capacity with different sized table quantities or -sorts to be supplied.

A sorting device for ceramic plates is known from the Austrian patent 190 448, whereby a band running past with compartments is arranged under a stacking container, which again extends over a number of cross conveyor belts on the lower side. The ceramic plates are removed from the stacking container, d. H. From here there is always a compartment of the intermediate conveyor link loaded. The brackets containing the individual panels are then placed on the underside loosened one or the other tape, so that the output of the disc contained in the compartment on the one or the other band takes place. Fixed triggers with stops are shown that accomplish the task the object of transport on one of the conveyor belts.

By the USA. Patent 2,537,005 a switching device is optionally available in transport systems Switching on one or the other separator for bulk material is shown. The U.S. Patent 2 611 493 contains a device with grippers or lifting rams that can be moved up and down hydraulically. With these grippers, for example, cans are picked up from one belt and another Band assigned. In the two USA patents, moreover, in general, the prior art Technical instructions for conveyor systems are given.

The object of the invention is to simplify the system and the possibility of adapting the entire device to the respective operating status and the individual mode of operation of each tablet packing machine to accomplish.

According to the invention, this is achieved in that a common one, which leads across all intersection points Lifting device for those to be transferred from the main conveyor to the cross conveyor the trays lying table rows is provided and that the allocation organs for transferring the table rows Arranged from the main conveyor to a cross conveyor at each intersection and via control devices can be switched on and off individually.

In this way, by means of the control device, each one leading to a packaging machine Cross conveyor belt is only ever loaded with the amount of chocolate bars that are processed on the packaging machine can be. The control devices assigned to the individual cross conveyors work appropriately depending on each other.

The idea of the invention allows a wide variety of possible designs, one of which is in the Drawing reproduced, namely shows

F i g. 1 is a side view of part of the main conveyor with the associated cross conveyors and FIG over this lifting device,

F i g. 2 shows a plan view of the system part according to FIG. 1.

The main conveyor is made up of the transport chains 3 and 4 running over the sprockets 5 and 6, on which by means of the support rods 8 and 9 grids 7 are provided, which the trays 13 with the Carry chocolate bars 1. Each tray has recesses 14 on the sides into which the later to be described Be able to grip the lifting device gripper from the side. About the, for example Main conveyors coming from the refrigerator are cross conveyor belts at a distance one behind the other

15,15 'and 15 "carried away, those in opposite directions Revolve directions. Of course, further cross conveyor belts can also be provided.

The crossing points of all transport organs are bridged by the common lifting device, which is driven by the main drive via the gears 11 and 12 and the drive shaft 20. On the drive shaft 20 sit chain wheels 19, over which chains 18 run away, on which at a distance of the plates 13 arriving on the main conveyor element, the guide bushes 21 close one behind the other for the lifting rams 22, which can be axially displaced therein, are seated. The lifting rams have at their lower ends 22 drivers 25 which engage from the side in the recesses 14 of the trays 13, and also at their upper end guide rollers 23 with which they lead in a lifting cam path 24 '.

The conveyor chains 18 are arranged on both sides of the main conveyor so that the trays 13 in the The driver 25 of the lifting ram 22 runs in and, as the movement continues, the axially in the sockets 21 upwardly displaceable lifting ram 22 corresponding to the shape of the cam track 24 'of the Support grids 7 to be lifted over the cross conveyor belts 15, 15 ', 15 ".

To the side of each cross conveyor belt 15, 15 'or 15 "is a scraper plate 27, 27' or 27", which is carried by holders 26, 26 'and 26 ", which are vertically displaceable in stationary sockets 30, 30' guided and actuated by a respective control device 31 or 31 '. For the conveyor belt 15 'is the control device 31 'is provided. In the case of the last conveyor belt 15 ″, the scraper 27 ″ is in its retaining bush 30 "immovable; it is arranged so high that just those arriving on the plates 13 Chocolate bars are scraped off by him and transferred to the conveyor belt 15 ".

Instead of the scraper, however, a tilting device for the trays carrying the panels can also be used provide so that the panels by pivoting force from the trays down to the underlying Cross conveyor belt slip.

The control devices 31, 31 'are electrical or electromechanical depending on the operating state the packaging machine connected to the assigned cross conveyor is operated and are coordinated in their work so that the associated scraper 27 or 27 'only occurs at time intervals. is lowered in order to transfer only the row of panels onto the associated conveyor belt 15, 15 ', their panels are to be packed on the panel packing machine connected to the belt and which are located on the Tray located, which is just between the running across the cross conveyor belt in question Lifting ram is held. It is understandable that you can switch the control and Drive devices 31 and 31 'always only specific rows of panels on the individual conveyor belts can transfer, with the timing and mode of operation of these controls can be adjusted as required. Of course you can also load more than three cross conveyor belts in the same way, with only the Extend lifting device accordingly and have to arrange even more control devices. Possibly you can easily the cross conveyor belts 15, 15 'and 15 "in their lateral distance change from each other and the work cycle of the system the special operating conditions on the individual Customize packaging machines. In this case the rollers 16 are for the cross conveyor belts to be arranged laterally adjustable with their drive motor 17.

The lifting device is located behind the cross conveyors 15, 15 ', 15 " 18 to 25 continued for the purpose of depositing the emptied trays 13 on the main conveyor 1.
