Method and device for removing rod-shaped articles or from the article-forming components of the tobacco processing industry of a conveyor track The invention relates to a method for removing rod-shaped Articles or the components of the tobacco processing industry that make up the articles from a conveyor track on which the articles or their components are in holding position be conveyed at defined, even intervals.

The invention also relates to a device for removing Rod-shaped articles or the components of the tobacco-processing components which form the articles Industry from a conveyor with the articles or their components picking up, holding means arranged at regular intervals.

When processing or assembling rod-shaped smoking articles it can lead to disruptions or interruptions in the flow of goods to which the items are conveyed or article components transporting funds come, here in particular in the area of the processing stations assigned to the funds or at the Transfer of articles or components from one conveyor to another.

The aim here is to avoid at least less serious operational disruptions to be resolved while the machine is still running to avoid prolonged production interruptions to avoid.

For this purpose it is necessary to have incoming articles or components to be temporarily excluded from further processing or before the source of the fault to be removed from the conveyor track.

According to DE-OS 2 842 834 (US-PS 4 237 907) it is proposed that Stw .: MAX roller device cleaning brush material feed interrupt - Iz to remove the articles held in suction troughs of a conveyor drum by temporarily interrupting the suction air or by briefly pushing compressed air. As a rule, the entire conveyor drum is affected by the interruption of the suction air, so that articles and their components fall off the drum in an uncontrolled manner or fly away from the drum in an uncontrolled manner, including articles that have already been assembled and not yet affected by the malfunction. These trigger new malfunctions, because they can no longer be transferred perfectly or in a clocked manner to the next following conveyor drums and thus cause a destructive article jam when entering the respective transfer area between two conveyor drums.

On the other hand, it has been shown that at today's high production speeds and the resulting short control times for switching off the suction air or

An orderly and perfect removal for the application of compressed air the article and its components are not guaranteed by the conveyor in every individual case is what can also trigger new disorders.

The invention is based on the object, individual articles or their Components specifically and with certainty at a precisely definable point from the Remove conveyor track.

This object is achieved according to the invention in that the article or their components removed by rolling from their holding position and before Reaching a subsequent stop position released or thrown from the conveyor track will.

If one of the components consists of a connecting plate attached to the rod-shaped article, the method according to the invention also includes the partial connection of the articles or their components by rolling on Stw .: MAX roller device-cleaning brush-interrupt material supply-I1 between two stop positions.

A frequent source of interference is in the area of a conveyor in the form of a rolling drum associated roll-over device, with which tobacco and Filter sections connected to one another by a glued connecting plate by placing the named components between rolling surfaces that are moved relative to one another the roller drum and a roller block are rolled over several times. Sit down in the course of time on the * 2component contacting rolling surfaces glue residues, which must be removed at regular intervals in order to avoid more serious malfunctions and avoid prolonged production stoppages.

A further development according to the invention is particularly helpful here, which consists in rolling and removing the articles or their components in the event of an interruption in a downstream assembly in the conveying direction effect of smoking articles made of tobacco and filter sections as well as connecting leaflets Rolling over and cleaning of the contact surfaces causing the rolling over takes place.

The articles or their components are expediently on a Circular arc-shaped conveyor track transported, preferably in the area of the respective holding positions in trough-shaped depressions acted upon by suction air be promoted.

The device for performing the method according to the invention is designed such that a roller block is assigned to the conveyor, the roller surface of which one that rolls or rolls the articles or their components between two holding means having releasing length before reaching the next holding means.

The device according to the invention can be used particularly advantageously in connection with a processing station at which double-filter cigarette sections by means of Jam .: MAX roller device-cleaning brush interrupt material supply-If a roll-over device is connected by a glued connecting plate, the contact surfaces of the roll-over device being cleaned prophylactically at time intervals or in the event of a malfunction. Here, too, the articles or their components have to be temporarily removed from the rolling drum. This is the aim of an expedient embodiment of the invention, according to which the roller block is provided upstream of a rolling device and cleaning device associated with this, based on the conveying direction of the conveyor designed as a roller drum, upstream of a smoking article made of tobacco and filter sections and connecting leaflets.

According to an advantageous embodiment, the roller block is here depending on a signal to shut down the roll-over device or for putting the cleaning device into operation by an adjusting means in a rolling position movable against the conveyor. After triggering such a signal, first the roll-on block is placed on the roller drum, then the roll-on block of the roll-over device pivoted away and the cleaning device by pivoting, for example one Cleaning brush activated. After a corresponding signal for restarting the reverse process takes place in that the cleaning brush is swiveled away, the roll-over block applied and the roll-on block is swiveled away.

It is useful if the rolling drum in defined, uniform Clearances with suction cups to hold the components is occupied.

According to an advantageous development, the rolling block extends in the area of the three o'clock position tangential to the rolling drum, so that the article following the force of gravity in a targeted manner in the collecting container provided below can be.

A jumping back of the rolled in and released articles Stw .: MAX roller device cleaning brush interrupt material supply-II on the roller drum is prevented according to a further embodiment in that the suction troughs in the Area of the rolling block connected to a vacuum source via a throttle channel stand so that the suction air acting in the holding troughs is in the area of the Article is weakened.

The advantage achieved by the invention is that the articles and their components are forcibly mechanically detected at a very specific point of the conveyor during a period of time that can be precisely determined from the beginning and the end and are connected to one another by rolling to such an extent that their complete removal from the conveyor is certain is guaranteed, so that after the malfunction has been eliminated, the normal delivery flow can be resumed without disruption.

Stw .: MAx-Rolleinrichtun9-Reini9un9sbürste-Interrupt material supply-IT The invention is described below using an exemplary embodiment shown in the drawing explained in more detail.

Here: FIG. 1 shows an overall view of a filter attachment machine of the MAX S type from Hauni-Werke, Hamburg 80, and FIG. 2 is an enlarged view a separation device assigned to a roller drum conveyor according to the invention.

Stw .: MAX roller device cleaning brush ~ Interrupt material supply-Il First, the structure and mode of operation of the filter attachment machine is briefly described: An infeed drum 1 transfers the items produced on a cigarette manufacturing machine Cigarettes on two staggered drums 2, which hold the stacked cigarettes disassemble and in rows of two with a space between the cigarettes to a compiling drum 3. The filter rods 4 come from a magazine 6 on a cutting drum 7, are doubled by two circular knives 8 to filter plugs Usable length cut, staggered on a staggered drum 9, by a push drum 11 aligned to a row of plugs lying one behind the other and from an accelerator drum 12 delivered to the assembly drum 3. Those formed on the assembly drum 3 Cigarette-filter-cigarette groups are pushed together so that they are axially sealed lying close together. They are then taken over by a transfer drum 13. A covering paper strip 14 is taken from a covering paper reel 16 by means of a pair of take-off rollers 17. The tipping paper strip 14 is drawn around a sharp edge Primary crusher 18 deflected around, glued by a gluing device 19 and on one Covering roller 21 cut by a knife drum 22. The cut topping leaves are attached to the cigarette filter groups on the transfer drum 13 and on a roller drum 23 by means of a roller block heated in a manner not shown 24 rolled a roll-over device around the cigarette filter groups.

To clean the rolling surfaces 26 and 27 of the rolling drum 23 and the Roliklotzes 24 in the pivoted state of the Roliklotzes from the roller drum 23 24 is a cleaning device in the form of a rotating brush roller 28 is provided, which from the end face of the Stw .: MAX roller device-cleaning brush-material supply interrupt-lT rolling drum 23 can be pivoted into the gap between the rolling surfaces is. Details of the actuators and control means for actuating the rolling block and a brush are described in detail in DE-OS 2 842 834 of the applicant and shown.

The finished groups of double filter cigarettes are placed over a drying drum 29 fed to a cutting drum 31 and on this by central cutting the filter stoppers through to individual filter cigarettes, with at the same time defective filter cigarettes will be ejected. One with a transfer drum 32 and a collecting drum 33 cooperating turning device 34 turns a filter cigarette row and transfers them to the transfer drum 32 and the collecting drum at the same time 33 continuous unused filter cigarette row.

The filter cigarettes reach an ejection drum via a test drum 36 37, on which also the head scanning of the filter cigarettes before the ejection process he follows.

A disc drum 39 cooperating with a brake drum 38 places the filter cigarettes on a transfer belt 41.

The rolling drum 23 is related to the conveying direction of the article in the form of cigarette filter groups 42 and covering sheets 43 upstream of the roll-over and cleaning devices 24, 28 a weeding device 44 for removal associated with the named components of the rolling drum 23, their structure and function is explained in more detail with reference to FIG.

The separation device 44 consists of a rolling block 46, the is provided with a relatively short rolling surface 47.

The rolling block 46 is made at the free end of a lever 48 which can be pivoted towards the rolling drum 23 or away from it about a stationary axis 49. To pivot the roller drum 23 in the three o'clock position Stw .: MAX-roller device-cleaning brush-interrupt material supply-II associated lever 48, this is articulated with an actuating rod 51 which can be driven by an actuating means in the form of a pneumatic cylinder 52.

During normal operation of the rolling drum 23, the rolling block 46 is in place pivoted away from the rolling surface 26. The individual components in the form of connecting plates 43 and the cigarette filter groups 42 are evenly spaced in corresponding Holding means of the rolling drum 23, which are designed as suction troughs 53, whose Suction connections 54 with a vacuum source brought centrally to the rolling drum 23 56 are connected. The connecting plates 43 are by additional, not shown Suction holes kept on the drum surface, which is for example in DE-OS Applicant's 3,201,859 (U.S. Patent 4,445,519). Running this way Components that are fed in are normally controlled by the adjacent roller block 24 the Überrolivorrichtung connected to each other.

As described in DE-OS 2 842 834, it can take place at certain time intervals be necessary as a result of soiling due to glue deposits on the rolling surfaces, switch off the roll-over device and clean the rolling surface, including a corresponding one Signal can also be triggered by a resulting article jam.

In this case, the pneumatic cylinder 52 is initially synchronized activated and the rolling block 46 in the position shown in Figure 2 against the rolling drum 23 pivoted. So that against a nose 57 of the rolling block 46 are running Cigarette filter groups lifted out of their respective suction cup 53 and that respective connecting plates 43 between the rolling surface 26 of the rolling drum 23 and the relatively short rolling surface 47 of the rolling block 46 on the cigarette filter group 42 rolled on. The components connected to one another at least in part in this way Stw.:MAX roller device cleaning brush material feed Interrupt-II are still in the respective movement segment between two Suction troughs 53 of the rolling drum 23 from the lower edge of the rolling surface 47 of the rolling block 46 released, d. H.

that they no longer reach the next suction cup or not more of this can be captured. The components released in this way fly vertically downwards into the ready-made collecting container 58 of the Masrhine. A stationary one arranged in the interior of the rolling drum 23 opposite the rolling block 46 Control block 59 forms a throttle channel 61 with the inner wall of the rolling drum 23, which weakens the suction flow in the suction troughs 53 moved past them in such a way that that Article 42 that was entered immediately and that was dropped downwards was not retrospectively can be caught again by the suction cups.

Meanwhile, the articles from the rolling drum in the manner described above 23 are temporarily removed, the rolling block 24 of the Überrolivorrichtung is pivoted and the brush roller 28 of the cleaning device from the drum face swiveled back and forth into the gap and driven in rotation, so that the rolling surfaces 26 and 27 are cleaned or freed from glue residues. Afterward the roller brush is swiveled back into its original position, the roller block 24 of the rollover device is moved into its operating position against the rolling drum 23 and only then is the roll-on block 46 swiveled away from the roll drum 23 at the right time, so that the articles are trouble-free and seamlessly on their conveyor track described above pass the roll-over device again.

Swinging out or swiveling away the roller block in accordance with the cycle 46 to or from the rolling drum 23 is done with the help of a not shown, clock usually used in tobacco processing machines, for example according to DE-OS 2 161 611 (US-PS 3 889 240), in order to ensure in the present case, that the first Stw.:MAX roller device cleaning brush material feed Interrupt-II records arriving articles to be sorted out in good time and the last item to be discarded over the entire roll length of the rolling surface 47 of the rolling block 46 is acted upon or the subsequent article is no longer recorded.
