Abstract

In a cigarette manufacture mechanical handling process the cigarettes are shifted transverse to the longitudinal axis and are released from a detent in a first drum to a detent in a second drum. During the transfer from one drum to the next the cigarette is subject to an impulse along the longitudinal axis.

Description

The The invention relates to a method for conveying a rod-shaped article the tobacco processing industry, the article being cross-axial promoted is and from a recording on a first conveyor to a recording of a second conveyor delivered becomes.

Under rod-shaped Articles of the tobacco processing industry are presented here Related such objects understood in single-layer series by means of suction on conveyors, such as on conveyor drums in cigarette manufacturing machines, held and promoted by these. Such articles are filter cigarettes, cigarettes, cigarillos, filter rods, etc. In the following, for the sake of simplicity, only cigarettes are spoken of the same applies to others as well to be promoted rod-shaped Article of the tobacco processing industry.

In a cigarette machine, cigarettes in a single-layer row across to their axial direction on conveyor drums, which are primarily drums of cigarette manufacturing machines or Filteransetzmaschinen is, held with suction. For this purpose point the conveyor drums suction air which are in communication with a vacuum source. The handover cigarettes from a first conveyor to the next conveyor takes place in The rule is that in each donating, first sponsor the Holding air in the transfer area is interrupted while the holding air is switched on in each receiving, second conveyor. In the case a handover from a conveyor drum on the following drum are to interrupt the holding air in which the transfer area forming peripheral portion of the first conveyor fixed in its interior Control segments arranged, which the suction air openings of the conveyor cover in this section and thereby disconnect from the vacuum.

For example, it is off EP 1 397 962 B1 in processes for conveying rod-shaped articles of the tobacco-processing industry.

Moreover, it is off US Pat. No. 3,699,974 (see there 4 ) known in the production of filter cigarettes tobacco rods in the absence of filter plug between two longitudinally spaced tobacco rods during their promotion on a conveyor drum in their axial axial distance by blowing towards each other zuzubewegen that the tobacco sticks are wrapped in a subsequent step with a tipping paper leaflet and then from the production process be discharged. The collapse of the tobacco sticks or incomplete smoking article group occurs before the alignment of the tobacco rod filter plug tobacco rod groups.

Further disclosed DE 27 42 856 A1 a device for the collapse of tobacco rods in malformed or missing double filters. The device is arranged on a compilation drum, wherein the tobacco sticks are not completely collapsed in the absence of double filter but are only approximated on the drum to each other to ensure sufficient overlap of the subsequently adhered pad paper leaflet.

outgoing from this prior art, the object of the present Invention in an efficient and simple way the longitudinal axial Distance from rod-shaped Articles of a smoking article group, in particular an incompletely formed Smoking article group, so it should be possible to have an incompletely formed smoking article group in a subsequent Step with a connection leaflet to wrap around a production stop at the manufacturing machine to avoid.

Is solved This object is achieved by a method for conveying a rod-shaped article the tobacco processing industry, the article being cross-axial promoted is and from a recording on a first conveyor to a recording of a second conveyor handed over or handed over which is further developed by handing over the article at the time of transfer the article moves by means of a movement pulse in the longitudinal axial direction becomes.

The Invention is based on the idea that at the transfer point between a first cross-axial conveying conveyors, e.g. a conveyor drum, to another conveyor, e.g. a second conveyor drum, while the cross-axial promotion and delivery the one to hand over Article at the same time a longitudinal axial Exercise movement. For this The article is made with a longitudinal axial directed movement impulse applied. This makes it possible, for example the longitudinal axial Distance from two tobacco sticks at an incomplete formed tobacco rod filter plug tobacco rod group, without intervening filter plug To shorten, the cross-axially promoted Tobacco-filter tip-tobacco strip groups from a first conveyor handed over to a subsequent sponsor become.

In an advantageous embodiment, transfer area in the holding vacuum, by means of which a tobacco rod filter plug tobacco rod group to be transferred is held on the first conveyor before being transferred to the following conveyor, is switched off or throttled.

at Finding an incomplete formed smoking article group, for example, without intervening Filter plug, is in the transfer area and with simultaneously reduced or switched off holding vacuum at the reception of the first conveyor the incomplete formed smoking article group from one or both sides or end faces subjected to a compressed air pulse, so that at least one rod-shaped article during the delivery in longitudinal axial Direction is moved or changed in its position.

In The subsequent production steps are the unconnected Smoking article groups consisting of several rod-shaped articles, such as tobacco sticks and Filter plugs consist, provided on a covering device with a connection papers, so that in a further step, the connection papers or Tipping paper to the full Smoking article groups (consisting of tobacco rod filter plug tobacco rod) and / or the incomplete Smoking article groups (consisting of tobacco rod or tobacco rod plug) wrapped and connected together.

If at the handover the negative pressure or the holding vacuum at the donating receiving trough of the first conveyor is discarded, the smoking article groups or their components are made the receiving trough in the transfer area solved. in this connection are the tobacco sticks or rod-shaped Article in the transfer area easily and safely displaceable by frontal Zusammenblasen. At the same time is the contour of the donor and the receiving Receiving trough on the first and second conveyor ensures that the smoking article group components safe from the first conveyor handed over to the second conveyor become.

To is provided in a further embodiment that the article after Shut down or reduce one to the receiving of the first conveyor applied holding vacuum is applied to the motion pulse, around a longitudinal axis Movement in the transfer phase from the first conveyor to the second conveyor while the transaxially directed transfer perform.

Preferably the article is acted upon on one end face with the movement impulse. If the longitudinal axial Distance between two tobacco sticks is to be reduced without intervening filter plug is it is possible that the tobacco sticks or the articles in each case on its outer end face with a movement impulse are applied, whereby the tobacco sticks longitudinal axial succession to be moved.

According to one Another embodiment, the article after or during a longitudinal axial Movement in the transfer phase in a receptacle of the second conveyor added.

To is further provided that at the receiving admission of the second conveyor while the handover phase or after handover Holding vacuum on the recording of the second conveyor is turned on or is.

Further It is advantageous if at least one article of an article group consisting of several rod-shaped Articles of the tobacco processing industry with a motion impulse is charged.

is for example, an incomplete smoking article group, consisting of two longitudinally spaced axially tobacco sticks without intervening filter plug, it is advantageous if two outside arranged articles of the article group in each case frontally with one Motion impulse are applied, so that the longitudinal axial spaced articles or tobacco sticks are pushed together, while she from a sponsor to the next Conveyor handed over become.

For this It is also advantageous if an incomplete, not as an article group sheathed Tobacco Stick Filter Plug Tobacco Stick Group is promoted, of which at least an article is imparted with a motion impulse, wherein complete unenclosed tobacco rod filter plug tobacco rod groups not be charged with a motion pulse.

Farther it is in one embodiment of Advantage, if by means of a sensor, the position of an article detected on the recording of the first conveyor is used to determine or record whether the smoking article group Completely, for example, with intermediate filter plug in a longitudinal axial spaced tobacco rod pair is formed.

moreover it is beneficial if dependent the location of the article article with a motion impulse during the handover phase is charged.

Farther is it advantageous in one embodiment when using a sensor monitors the completeness of an article group becomes. This makes it possible in particular that depending on Absence of an article from the article group at least one article, preferably two articles, with a motion impulse applied becomes.

To produce filter cigarettes, the Article groups connected by means of a connecting sheet in a subsequent step. For this purpose, the connecting papers or covering paper leaflets are adhered to the smoking article groups and wrapped by the connecting leaflet.

According to one preferred training is also provided when the to be handed over Article during the handover to the following, second conveyor by means of the contours of the receiving troughs or the flanks of the receiving troughs the first and / or the second conveyor is performed.

Besides that is it is advantageous if the motion pulse is effected by means of a blast of compressed air, wherein in the transfer area at least at one end face of the conveyor or the conveyor drum a Compressed air source is arranged. In particular, on both sides the conveyor drum Compressed air sources provided to both sides of the tobacco sticks a Group of smokers towards each other while the incompletely formed Smoking article group is passed to the subsequent conveyor. This works according to the longitudinal axis Distance of the tobacco sticks by a longitudinal axial caused movement of the tobacco sticks, wherein the holding vacuum on the first conveyor in the region of the transfer area is reduced or switched off.

The Invention is described below with reference to an illustrated in the drawings embodiment described in more detail.
