set directions and move with the conveyor rail 4 are connected via transmission stations 8 and 9. Γΐ3Γ Cross conveyor 6 moves empty trays that are attached to the Station 8 are delivered, back to the return line for the purpose of recirculation through the loading station. Opposite fcswegt the cross conveyor 7 filled trays that are attached to the Sllation 9 are delivered, across the flow for the purpose of re » uKiIaufo through the unloading station · In any case be Sihragen, whether filled or unfilled, the moment are not required, stacked in a row along the respective cross conveyor and in their position on dom cross conveyor held by arranging means, wherein the conveyor belt slides under the trays »

Joder automatic tray filler 1 has an unloading area form 10 for empty trays and downstream thereof a charging platform 11 for filled trays and additionally he waist a container in which cigarettes from a cigarette ~ r »ttenheratellmaschin ί are promoted, as well as a filling« mechanism open, the empty tray from the unloading platform- » Fills form 10 with cigarettes and moves the filled trays onto the charging platform 11

Each tray emptier performs an opposite function and has an unloading platform 12 for filled trays and downstream of the same a loading platform 13 for empty trays and also an emptying device 1 smus on « the cigarettes from the trays on the unloading platform 12

Emptied into the storage container of a packaging machine and the emptied trays are moved onto the loading platform 13.

The winches 3 cooperate with the means provided at each station in a manner to be described in detail in order to deposit one or more trays of only one type, ie filled or unfilled, on the unloading platform and the same number of trays of the other type from the loading platform to decrease. Each of the transfer stations 8 and 9 and each sohrage filler 1 and tray emptier 2 is provided with gowns which determine the type of trays offered by a traveling winch so that they can be accepted or rejected accordingly. The determination can be supported by marking the trays depending on whether they are full or empty. His way of discovering this is to provide a photoelectric test device and openings in a wall of each socket which can be attached to the test device and which are covered by cigarettes when the socket is filled. The means which cooperate with the hoists are also so been "assigned" to be selectively movable in an operating position or out, depending on whether a tray "or exchange required or not.

This system can be used to feed more than one type of cigarette at the same time. Certain manufacturing

the irregularity between packaging and manufacturing, which the system can compensate · The number of trays for each type on the conveyor 7 for felled trays forms an indication of the difference in the manufacturing and packing speeds for this variety and may can be used to change these speeds accordingly, thus reducing the difference between them.

Each! Winch is with a slope or a set of Provided with slopes and - again because of the slope · » Tausohes - she always wears a cradle, except during dee short run between an unloading and a loading platform.

During the normal work of the system under theoretically perfect conditions in which the overall speed of cigarette making for each variety is equal to the total speed of packaging each variety, the Winches 5 along the rail 4 are moved at a speed that is equal to the packaging and manufacturing speeds; there is no exchange at the exchanger ▼ on Sohragen and the number of trays in each cross conveyor torrent remains constant

So will the number of cigarettes which was manufactured more than cigarettes were packed, in an increase in the number of filled trays on the Cross conveyor 7 reproduced · Correspondingly, if one manufacturing machine works slower or stops, the next one empty tray, which is intended for the manufacturing machine, continue to the transfer station and since it is a empty and not a felled tray, it is exchanged for a filled tray, where sioh the relative number of trays in the Qmer conveyors 6 and 7 in turn changes. In this way the number of packaged cigarettes will match the number of cigarettes produced exceeds, shown in an increase in the number of empty trays on the cross conveyor 6. When the system starts up It is necessary to provide some filled trays on the cross conveyor 7, so that the system delays can compensate "which occur when the Zlgarettennerstellmaeehine start up"
