Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The device b° of the invention is known in the tobacco industry as a "pigeon mass feeding device" (7) for conveying paper in the sanitary line of inspection or from this line to the packaging line. It is advantageously used in packs intended for transporting cigarettes.

As is known in the prior art, in a 111-type positioning system, the articles are moved forward as a whole by the conveyor belt into a layer of thickness 1i17.

In this downstream part, the cigarettes are often led into a passageway with fixed walls, while in the upstream part the cigarettes on the top of the conveyor are placed in the opposite direction. Restraint is provided by means of a pair of restraint strips delimiting the layer of tobacco on the sides.

When the filter is applied to the tobacco being treated, transport devices of the known type operate precisely in the area along which the smoke filter is transferred between two different heights. First, it is known that this phenomenon is particularly observed in the downstream part. The cause of this accident is that the diameter of the cigarette body and the diameter of the filter attached to the end of the cigarette are different. The latter i.e. f.
The diameter of the filter is actually larger than the diameter of the cigarette due to the presence of the band connecting this filter to the cigarette.

Even though the standards for said belt are very limited,
The presence of this band causes this non-negligible problem whenever cigarettes are conveyed forward in a substantially vertical path of considerable length; It follows that the number of stacked cigarettes is particularly large in such cases, and that the total height of the stack of filters 11+11 is noticeably higher than the total height seen on the side on which the other end of the cigarettes lies. For this reason, in the place where the stack is slightly higher, the direction in which the cigarettes lie is significantly different from the horizontal plane9, and this is the reason why the cigarettes are located in the L4TJ: t defective position. Therefore, it is necessary to temporarily suspend the operation of the transportation device.

The problem outlined in point 11 above occurs very frequently in the modern tobacco industry, which necessitates a number of stages in the production cycle depending on the number of floors in a building. This is due to the installation of significantly expanded mechanical equipment. For example, there is a machine for manufacturing cigarettes that is installed on a large floor and a filter is attached to the bottom of this floor.The normal method is to install a packaging line directly under the floor. During production, it is necessary to transport cigarettes (r-) between regions that differ greatly in height, and 1i
It is clear that this poses particular problems as stated in tJ'7).

OBJECTS OF THE INVENTION It is therefore an object of the invention to construct a useful transport device of the above-mentioned type in which the problems mentioned for the prior art do not occur.

SUMMARY OF THE INVENTION This and other objects of the invention also include a device for transporting rod-shaped articles, in particular cigarettes, between two areas of different heights, in which the rifling stick has its axis. In the transversely forwardly layered, 7 carried device, there are at least two substantially vertical conduit passages arranged at different heights and spaced apart in one horizontal plane; A pair of passages are connected to each other by means of substantially horizontal conduits at a distance of λ1, the horizontal passages having their entrances below and having similar exits. This is all achieved by the device of the invention being placed in the area of the inlet of one of the channels. BRIEF DESCRIPTION OF THE DRAWINGS The features and advantages of the invention will become clearer from the detailed description according to the preferred 3F4 design, shown by way of example and not limited to the accompanying drawings. The drawing is a diagrammatic front view of the device of the invention.

Referring to the drawings, a device for cigarettes (hereinafter referred to as cigarettes) 2, indicated by the general note 1, is shown as shown in the drawings.
, is equipped with two horizontal conveyor bells l-3, 4e located on the left and right respectively.

The two conveyors are each composed of belts 5 and 6, and the belt 5 runs around a pair of rollers 7 in an endless manner, and the belt 6 runs around a pair of rollers 8 (middle and 6). 1, supported and driven by shafts 9 and 10, respectively; said conveyors 3 and 4 are in the upper part of the device 1; These conveyors run from opposite sides towards the top or entrance of a narrow vertical passageway or conduit 11 bounded by two vertical, mutually parallel walls 12 and two 2" opposite side walls. A conveyor belt substantially parallel to the conveyor 3 or a right end of a connecting passage 13 is arranged on the F side of the lower end of the 5° passage 11 converging at
This conveyor 13 is supported by a corresponding shaft 16 parallel to the shaft 9 and comprises a belt 14 which is endlessly attached around two rollers 15 which are moved by vi. The other end of the conveyor 13 communicates with the upper end of a vertical passageway 17 which is laterally limited by two walls 18 parallel to the wall 12. Front n conduction path 17
The lower end of the conveyor belt 13 is located on the F side at the same level as the conveyor belt 13, or the earth kc at one end of the connecting passage 19, and this conveyor I9 is il'llll l G
The other end of the front nlL conveyor 19 is a vertical narrow belt comprising a belt 20 mounted endlessly around two end rollers 21 supported and driven by parallel corresponding shafts 22. It communicates with the two ends or inlets of a passageway or conduit 23, which passageway 23 is in line with the aforementioned passageway 11 and parallel to the wall 12, and is thus restricted to two opposite side walls. .

In use, said conveyors 3 and 4t carry cigarettes 2 coming from a production or storage station, not shown, and conveyed forward in the form of layers whose size substantially corresponds to the diameters of a single cigarette. , continuously in the passage 11.

Looking 11'' through the passage 11.

Cigarette 2 goes up aisle 1; 1 and goes forward here; 1-v of jl:
Form a moderately thick layer of grass 2 with no slope. The cigarettes 2 are then inserted into the channel 17, passed through this and placed on the channel 19 in the same manner as described for the channel 1:3, after which these cigarettes pass into the channel 23 (7 after which It is then sent forward to a processing department (not shown).

From what has been said so far, the passages 13 and 19
The effect produced by a single vertical 11 of considerable length
It is clear that by using a long path the aim is to prevent the above-mentioned problems that naturally occur while transporting cigarettes 2 between two different heights. The placement of suitable horizontal passages of the type tested, along the vertical elongated passageways, in practice prevents excessive slope of the grass at each point in the conveyance path. The reason for this is that the aforementioned result is due to the correct selection of the lengths of the vertical elongated channels 11, 17 and 23 and the inclination f of the cigarette 2 in the upper part of the channels.
This is because t1 is set within a limited range.

Many modifications may be made to the above-described apparatus without changing the principles of the invention and without exceeding the scope of protection afforded by the invention.

The transport surfaces of the conveyor belts 13 and 19 may be, for example:
Said passage II by means of these transport surfaces.

The angle formed between 17 and 23 J]6
A moderately thick layer of cigarettes 2 on the surface i (- can be inclined with respect to the horizontal under conditions such that it can be formed, and these one-layered surfaces); l, if the If the slope is such that the cigarette can be moved forward independently by the action of gravity, it can be constructed by a fixed surface.

Furthermore, the number of horizontal passages arranged along a vertical transport path can be freely selected depending on the length of this horizontal passage and the position of the end of this horizontal IRF + passageway covered by one of the elongated nozzles L (1). It can be anything you like.

The device of the invention can also be used advantageously even in cases where said passages 11.17 and 23 are not exactly vertical.

It should be noted that it can be concluded that the horizontal passages of note 2 can also be provided in vertical transport paths in which the cigarettes 2 are moved forward and upward. In this case,
The only important difference to the devices described so far is that the walls 12, 1 of the passages 11, 17 and 23
8 and 24 will be replaced with conveyor belts.
