Abstract

PROBLEM TO BE SOLVED: To provide a method for organizing transferred materials in a single line, such as a cigarette, a cigarillo, a cigar or a filter rod, in a tobacco industry into a multilayered materials flow and an apparatus therefor. SOLUTION: A speed of materials sent on a separated transferring path in a shape of partial rows is reduced and the materials are piled with each other to form a multilayered materials flow, then transferred. The apparatus has stopping mechanisms 17 and 39; 22 and 41; 28 and 42 for partial rows 8, 9 and 11 and a transferring means 47 for a materials flow 50 formed from the partial rows piled with each other.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for knitting a row of moving articles in the tobacco processing industry into a multi-layered article stream by forming multiple rows of articles from the row of articles. Furthermore, the invention relates to an apparatus for knitting a row of moving articles in the tobacco processing industry into a multi-layer stream of articles by means of a number of sub-row forming means.

[0002]

BACKGROUND OF THE INVENTION The concept of "articles" in the tobacco processing industry refers to cigarettes, cigarillos or cigars and filter rods with or without filters. These articles have an annular shape or a different shape (eg, oval) in cross-section perpendicular to its longitudinal axis.

[0003] The term "multi-layer flow" refers to a moving article configuration having two or more articles that are stacked one on top of the other. Articles in the tobacco processing industry, especially cigarettes and filter rods,
These articles are generally transported in a single row, while these articles are present in a reservoir of a suitable transport means, for example a drum, and are transported transversely to their longitudinal axis. Because of the high speed of such rows, articles of a single row are usually transferred to a stream in which multiple layers of articles are in close contact with each other and are side by side and one above the other. The speed of the articles in the stream being transported is correspondingly low for the next processing of the articles, for example for packaging, so that the risk of damage during the transport of the articles is small. Transfers in one row and one stream, i.e., the transition point to the formation of an article stream, are areas that require careful treatment. This is because in this position there is a risk that the cigarettes will be damaged or their axis-parallel form will be destroyed, which will lead to transport disturbances.

[0004]

SUMMARY OF THE INVENTION The object underlying the present invention is to ensure that the transfer of articles transferred in a single row to a transfer configuration as a multi-layered article stream is ensured without damaging the cigarette. That is.

[0005]

SUMMARY OF THE INVENTION The object of the invention is to provide a method according to the invention in which the speed of an article which is fed in a partial row on a separate transport path is reduced, and subsequently the article in multiple layers The problem is solved by stacking and transporting each other to form a stream. Other advantageous embodiments of such a method according to the invention are described in claims 2-5.

Furthermore, an apparatus of the type described at the outset for carrying out the method described above is distinguished by a braking mechanism for the sub-rows and a flow of articles formed from the sub-rows stacked on one another. Is provided.
Other advantageous configurations of such a device are defined in claims 7 to 9. The present invention will be described in detail below with reference to the embodiments of the invention illustrated in the accompanying drawings.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A row of evenly spaced layers 1 of egg-shaped cigarettes 2 is transported in the direction of arrow 6 by a transfer drum 4 provided with a tub 3 for accommodating cigarettes, not shown. It is transferred from the manufacturing machine to the delivery station 7. The cigarette 2 is held in the tank 3 by suction air in a known manner. At the transfer station 7, a number of sub-rows 8, 9, 11 in the present case are formed from the cigarette 1. For this purpose, tank 1
The first sub-row drum 12, which has 3-the distance between each other is about three times as large as the distance between the tanks 3, is the cigarette shown at the time of pick-up, the third cigarette, the sixth cigarette, , The ninth cigarette and the next cigarette are removed and supplied to the first ramp 17 according to the arrow 16. The vessels 13 each have a hole 14 through which suction air is guided from the annular negative pressure line 15 to the bottom of the vessel 13. Therefore, the cigarette 2 is delivered into the tank 13 by suction air from the tank 3. For this purpose, the negative pressure in the tank 13 mainly exceeds the negative pressure in the tank 3 or the tank 3 is designed such that the pressure is released at the time of delivery by a known control device, not shown. I have.

The first, fifth and seventh negative-order cigarettes are used as second sub-rows 9 as second sub-row drums 19.
And is sent to the second inclined portion 22 according to the arrow 21. The tank 18 is also provided with holes 23, which are connected to the annular negative pressure line 24 while the cigarettes of the second partial row 9 are being fed, so that the cigarettes of the second partial row 19 Suction air draws from tank 3 to tank 18 where it is held during the next transfer.

The second, fifth, eighth and next cigarettes are withdrawn from the tank 25 of the third sub-row drum 26 as the third sub-row 11, and into the third inclined part 28 according to the arrow 27. Sent. The tank 25 also has a hole 29,
These holes are connected to the annular negative pressure line 31 during the transport of the third sub-row 11 of cigarettes, so that the cigarettes of the third sub-row 11 are transferred from the tank 3 to the tank 25 by suction air. Is picked up and held there for the next transfer to take place.

The speed of the tubs of the partial row drums 12, 19 and 26 is equal to the speed of the tub of drum 4. When reaching the inclined portions 17, 22, 28 to which the cigarettes of the first, second and third sub-rows 8, 9, 11 belong, the action of suction air in the holes 14, 23, 29 is reduced. Disappears, so the cigarette moves down the slope by gravity. This movement is indicated by arrows 32,33,34. The negative pressure chambers 36, 37, 3 are provided on the inclined portions 17, 22, 28.
8 are bordering. These negative pressure chambers are connected to the inclined surface via slits or holes 39, 41, 42, and the cigarette is braked on its way down by the suction air flowing through. That is, the speed of the cigarette is reduced. The vacuum chambers 36, 37, 38 are connected via conduits 43, 44 to a known vacuum source, not shown.

The cigarettes of the first sub-row 8, which slide down while braking the first ramp 17, are guided via two rollers 48, 49--one of these rollers being driven. Conveyor belt 47. The cigarettes form a stream of, for example, three layers on the conveyor belt 47. On this layer, a cigarette that slides downward while braking the second inclined portion 22 is placed as the next layer. The same is true for cigarettes that slide down while braking the third ramp 28. Thus, all of the cigarettes on the conveyor belt 47 form a multi-layered moving article stream 50 of cigarettes whose transport speed is only a fraction of the speed at which the cigarettes 2 are transported on the transport drum 4. I do.

The speed of the conveyor belt 47 is detected by the scanning members 51 and 52 by a known method. These scanning members scan the layer height and, depending on this height, control the conveyor belt drive mechanism so that the height of the articles on the conveyor belt remains at least approximately constant.

[0013]

An advantage of the present invention is that a single row of articles fed at a high speed is first split into partial streams and then
Before the articles are formed into a multi-layer article stream moving at a slow speed, the knitting of the articles, e.g., cigarettes, into multiple layers is performed by the articles being braked as sub-rows while they are being transported. Without damage to the cigarette.
