Definitions
- the invention relates to a method for loading a smoking machine with cigarettes which are automatically introduced into a cigarette holder having a seal and a stop.
- the invention further relates to a device for performing the method.
- Cigarettes lying in a guide, are pushed forward into the holder by a pusher.
- the cigarette is pushed into the opening of the sealing disc until it hits the stop. More or less force is exerted on the cigarette to open the sealing lips of the sealing discs. This can lead to deformations, particularly in the case of filterless cigarettes.
- the sharp paper edge of the cigarette filter places a relatively heavy load on the thin sealing lip of the sealing disk, which necessitates replacement of the sealing disk after a short time.
- the invention has for its object to provide a method for loading cigarette smoke machines or to create a corresponding device with which or with which a very reliable loading of the smoking machine while reducing the service life, in particular also when changing the loading with cigarettes of different dimensions is possible.
- the object is achieved according to the invention in that the cigarettes are each brought into a loading tube and the loading tube is pushed through the seal of the cigarette holder.
- the seal which can consist, for example, of several sealing lips or sealing disks or of labyrinth seals, is subjected to considerably less stress than if the sharp-edged cigarette is inserted without the loading tube.
- the seal has to be replaced less frequently, so that the service life of the smoking machine is shorter.
- the method according to the invention has the advantage that the sealing lips of the sealing disks are bent outwards by pulling out the loading tube after inserting and inserting the cigarette and thus holding the cigarette bent outwards, with pressure on the Cigarette arises in the direction of the stop. The cigarette is therefore held firmly and securely and reliably pressed against the stop even during the smoking process.
- the sealing lips are bent inwards so that the cigarette can be pushed away from the stop in conventional arrangements.
- the automatic loading is facilitated in that, according to one embodiment of the invention, the cigarette is made from a nem falls through an opening in the loading tube in the loading tube.
- the cigarette is pushed or pulled into the cigarette holder by an overpressure or underpressure formed in the loading tube. Due to the overpressure or underpressure, only a slight force is exerted on the cigarettes, so that filterless cigarettes in particular are not deformed. Due to the positive and / or negative pressure, the cigarette is brought into the correct position, so that the adjustment and adjustment of a plunger as a function of the respective cigarette dimensions is dispensed with. In particular, it is not necessary to readjust or change the system if it is to be fitted with cigarettes of different lengths or diameters. This also significantly reduces the downtime of the machine.
- the adjustment is easier not only with regard to the cigarette length, but also with regard to the cigarette diameter, since the cigarettes are also pushed or pulled through the loading tube with different diameters, so that normally there is no change in the diameter of the loading tube when the cigarette diameter changes is required. Only when there is a major change in the cigarette diameter would a loading tube with a different inside diameter have to be used. With a smaller cigarette diameter, it is only necessary to increase the overpressure or underpressure in order to compensate for the fluid flowing between the cigarette and the loading tube.
- An overpressure is preferably generated by the inflow of an air stream on the side of the cigarette facing away from the cigarette holder in the loading tube.
- An embodiment is particularly advantageous in which the charging tube is pulled out of the cigarette holder without a cigarette after the charging process and the overpressure or underpressure is maintained during the withdrawal.
- the overpressure or underpressure therefore still presses the cigarette against the stop, which, for. B. can be a perforated disc.
- the lips of the sealing disk take over the holding and sealing function. Only then is the positive or negative pressure switched off.
- the lips of the sealing washers are pulled outwards through the loading tube, so that there is a slight force on the cigarette in the direction of the stop.
- a device for loading a smoking machine with cigarettes in which a loading tube is provided, in each of which a cigarette is inserted, the loading tube being able to be pushed into the holder through the seal through a drive element.
- the loading tube is preferably at least partially slidably mounted in a guide tube.
- the loading tube preferably has an opening for inserting a cigarette into it. It is advantageous here that the guide tube has a corresponding opening for inserting the cigarettes into the loading tube, the opening of the guide tube essentially being that
- the opening in the loading tube corresponds and these openings lie one above the other when the loading tube is in its starting position, that is to say in the position in the guide tube facing away from the cigarette holder.
- the guide tube covers the opening of the loading tubes when the loading tube is in the front position facing the cigarette holder. In this way, the loading tube is closed, so that the overpressure or underpressure is not impaired by the opening for loading the loading tube with cigarettes.
- the end of the loading tube facing the cigarette holder is rounded.
- the driven element is preferably formed by the piston of a pneumatic cylinder. This enables a drive for the charging tube to be provided easily and at low cost.
- the piston of the pneumatic cylinder is fixed by means of a plate or arranged perpendicular to the loading tube axis or piston axis
- the pneumatic cylinder is attached to the guide tube. This enables a compact arrangement of the elements of the device, which is also mechanically stable.
- the guide tube and the pneumatic cylinder are connected by a disk arranged perpendicular to the guide tube or pneumatic cylinder axis, both the end of the guide tube and the end of the pneumatic cylinder being connected through the disc are passed through, and are attached to the implementation with this.
- the guide tube with an opening which, in the state in which the loading tube is fully inserted into the guide tube, corresponds to the opening in the loading tube. This enables automatic loading of the loading tube through the guide tube.
- the air flow which generates the air pressure in the loading tube is advantageously blown in by a blower at the end of the guide tube facing away from the cigarette holder. This is a simple method for generating the air flow or overpressure in the loading pipe. Additionally or alternatively, a suction device for generating a negative pressure is provided.
- FIG. 1 to 5 a cross-sectional illustration of the device according to the invention in several drain positions to explain the method according to the invention
- FIG. 6 a cigarette holder with inserted loading tube
- FIG. 7 the cigarette holder with the charging tube already slightly pulled out and the cigarette pushed in, a vacuum being applied to the end of the stop opposite the cigarette
- FIG. 8 the cigarette holder with a cigarette inserted through the loading device, the charging tube already being is pulled out
- Fig. 9 shows the cigarette holder with a cigarette inserted according to conventional methods.
- FIG. 1 to 5 show a cross section of the device according to the invention, by means of which the cigarette 1 is introduced into the cigarette holder 2 in five steps.
- the cigarette 1 falls from a storage container (not shown) into the openings 1 a and 1 b of the guide tube 4 and the charging tube 3.
- the charging tube that slides in the guide tube 4 is pushed completely into this in FIG. 1.
- the loading tube 3 can be moved by the piston rod 5 of the pneumatic cylinder 7, both the loading tube 3 and the piston rod 5 being inserted into the plate or disk 6 perpendicular to the loading tube axis or piston rod axis and being connected to the feedthrough.
- the pneumatic cylinder 7 is connected to the guide tube 4 via the plate or disk 8 perpendicular to the guide tube axis or pneumatic cylinder axis. Both the end of the guide tube 4 and the end of the pneumatic cylinder 7 are passed through the disk 8, and they are connected to this disk at the bushing.
- the pneumatic cylinder 7 is connected to the disk 8 via a lock nut 9.
- FIG. 2 shows how the cigarette 1 is inserted into the charging tube 3, but is still located at the position of the opening 1a in the guide tube 4 or 1b in the charging tube 3.
- the loading tube 3 has already been inserted into the cigarette holder 2 by the moving piston rod 5 with power transmission via the disk 6.
- the cigarette 1 is still located in the region of the opening 1b of the loading tube, which is, however, already shifted to the left in relation to the opening 1a in the guide tube.
- an air stream is blown in at the end of the guide tube facing away from the cigarette holder, which continues into the loading tube and pushes the cigarette 1 into the cigarette holder 2.
- the cigarette 1 has already been inserted into the cigarette holder 2.
- FIG. 5 shows the loading tube 3, which is retracted by the piston rod 5 with power transmission via the disc 6, the cigarette 1 remaining in the cigarette holder 2, on the side facing away from the cigarette, a vacuum being applied to hold the cigarette.
- FIG. 6 shows the cigarette holder 2, into which the charging tube 3, which is rounded at the front, is inserted, specifically through the sealing lips 10.
- the sealing lips 10 are bent to the left at their ends, which has been done by inserting the charging tube 3.
- FIG. 7 shows the cigarette 1 which is inserted through the loading tube 3 and which is pushed into the cigarette holder 2 and which abuts the stop 11 with its filter end.
- the loading tube 3 remains in the position already shown in FIG. 6 in front of the stop 11, but it is still located in the area of the sealing lips 10, which are still bent to the left at their ends.
- FIG. 8 shows the cigarette inserted into the cigarette holder 2 with the loading tube 3 already pulled out.
- the ends of the sealing lips 10 are bent to the right by pulling out the loading tube 3 so that they exert pressure on the cigarette in the direction of the stop 11.
- FIG. 9 finally shows a cigarette 1 inserted into the cigarette holder 2 manually or with a conventional automatic loading method, the ends of the sealing lips being introduced by inserting the cigarette are bent to the left without loading tube 3 and exerts pressure on the cigarette away from the stop.
- the cigarette can be inserted into the cigarette holder both by exerting an overpressure in the loading tube on the cigarette and by exerting a negative pressure from the side of the cigarette holder or by a combination of both methods.
