The opening of the chamber 11 extends over the curvilinear portion of the belt 12 around the roller 13 through which the negative pressure is exerted.

The upper section of the upward strand of the Belt 4 can be opened with the aid of a hammer 14 15 adjacent to the inner surface of the belt 4, are also subjected to a negative pressure. By the shape of this Chamber is given the opportunity to subject the curvilinear path of the belt around the roller 6 to a negative pressure. The chambers 14 and 11 are connected to the same source of depression; the exchange takes place from one hammer to another with the help of a pneumatic dust board (not shown).

The function of the device is based on the following principle. You on the belt 1, coming from the manufacturing machine, deposited cigarettes are fed to the angle formed by the two belts 1 and 4. Under the influence of The suction force, which is brought about by the negative pressure prevailing in the chamber 9, removes the cigarettes individually from the belt 4 added * If the chamber 11 is pressurized, they will continue on their upward trajectory up to the overlap area of the two chambers 9 and 11, where they oppose the effects of the suction force Sighting are exposed.

When they reach the area in which the suction effect of the ammer 9 ends, they leave the belt 4 and are thrown onto the belt 12, on which they are held with the help of the suction force created by the vacuum existing in the chamber 11. Then they are guided along the horizontal path of this belt Λ2 to a stretching machine or a reservoir serving as a storage buffer.

If the packing machine or the reservoir can no longer take up the production of the Hersfcellungsmaschine, there is _: the possibility of temporarily preventing the transfer of the belt 4 to the belt 12 with the aid of the above-mentioned dust board, so that the cigarettes can move in the direction indicated by arrow 17 on the belt 4, where they can be stored as a reserve or fed to the available reservoir of another machine.

Figure 2 shows an example of an implementation in which opposite the lifting belt 4, a second conveyor is provided for resumption. in this case it is r chamber of the belt 4 into four separate fields 22, 23 ,. 24 and 25 subdivided; the section of FIG. 27 located below is opposite the upper section of FIG. 27, the lower section of which Section is opposite the top section of Fig. 25; the the lower section of 25 rises above the lower section of 27 "

This device clearly gives the possibility the flow of cigarettes raised by 4 by changing the pressure in the various suction compartments accordingly into one or the other, according to the arrows 17 »1β and 26 directed currents.

. The change in pressure takes place in the form that ™ the chambers 27 and 25, which are connected to one and the same source of depression, are exchanged by means of a dust board; the same thing happens with the at one other depression source connected chambers 11 and with the help of another dust board. When the chambers 22 and 23 are directly connected to the same source and the negative pressure in the feed chambers is the same, one of the following solutions is possible:

- Current flow according to arrow 26, due to that created in 27 Negative pressure. The ammer 25 is not fed here.

- Flow according to arrow 18 by exchanging between 27 and 25 as well as due to the negative pressure created in 11. The chamber 24 is not fed. ,

- Flow according to arrow 17, with the aid of a simultaneous exchange of the negative pressure in chamber 11 to chamber 24 as well as chamber 27 to chamber 25

to the
In order to get back to one or another previous status, it is sufficient to restore the pressure in the chambers 11 or 27 by means of a corresponding exchange.

According to the arrangement of Figure 2, the change in pressure can take place in different ways. When the four chambers 22, 27, 23 and 11 are in permanent negative pressure and have the same values, it is sufficient to see the changes in the To obtain the flow according to the indicated arrows, chambers 25 and 24 according to the values that are higher than the previous values to put under negative pressure. Due to the negative pressure created in the chamber 25, the flow led to the high-lying section of the device where the belt adjacent to the chamber 11 controls the flow according to ' Arrow 18 directs. By created in the chamber 24 Under pressure, the direction of the current, which runs according to arrow 17, is also changed.

According to Figure 3, the chamber 33 of the conveyor 32 is not divided into fields.

The negative pressure prevailing in this chamber is just enough to keep the conveyed products in contact with the conveyor belt. This negative pressure can be all the smaller than the angle α which the conveyors 31 and 32 form with one another is greater: an obtuse angle α which is useful gravity is therefore preferable.

The negative pressure in the chambers 36 and 37 is far greater Meaning than that in ammer 33. It is especially sufficient to create a suction that is capable is the products by 3? laid in contact with tapes 34 and 35, tighten, ohm? that this is a Suppression of the negative pressure in 33 would be necessary.

The conveyor 32 is connected to the inlet opening 40 a reservoir 39 of variable volume connected. The exit port 45 of the reservoir, which is above the conveyor 42, which adjoins the conveyor 34, is arranged, is provided with a flap 43 that the reservoir closes in position 43a and releases its contents in position 43b. A detector in the form of a wing 38 is provided above 45 above conveyor 34. Developed along with his contact 46. Above 45 is over a detector in the form of a wing 42 is provided for the conveyor 41, who works with his contact 47.

The function of the device is based on the following principle:

When commissioning the device

- a negative pressure is created in chambers 33 and 37,

- the bands 31, 32, 34 and 35. sit in the direction of the arrow moving,

- In the chamber 36 a negative pressure is created until the The level of the products under the wing 38 has reached the desired value based on the position of the contact 46 is measured. Now the suction is interrupted at the same height as the chamber 36 with the help of a dust board; the manufactured products are guided to the reservoir 39 by the belt.

If the packing machine, under these conditions, cigarettes requests., the distributor belt 41 starts moving in the direction indicated by the arrow and relocates the accumulated products in the zone 44. The - ^ rfkopf 38 lowers, whereby the contact with 46 is broken and a vacuum is again created in the chamber 36; through 32 upscale products are passed through 34 again under the ^ reef head.
