Method for inserting a filter insert in a mouthpiece for cigarillos and a device for Pure execution of the procedure.

Varying invention is a method sun bring a filter insert into a mouthpiece for on a machine for placing the mouthpiece on CigftriHQ, in which the mouthpieces with the opening; after, ohen a.-η Hagaainkanal are supplied, as well as one for Implementation of this, method suitable device.

There is a general problem with such methods that if possible in the production of cigarillos

in which a filter is inserted, $ a, see, can be used, the b, is heytf * m Attaching a mouthpiece without a filter to a were used, this is only possible

the opening r «9ch qfcen can be in one pm. The prerequisite d, 4e iiage d, cs center of gravity of the mouthpiece, ^ ann / cUeser center of gravity in that of the Qeffnunß GJ ) ; _{lies t the} mouthpiece of

Vibratory conveyor can be brought into a magazine channel in the relevant position. In other words This had to be taken into account with the previous methods for attaching mouthpieces with filters to cigarillos that through the filter, which is inserted into the vibratory conveyor before the mouthpieces are brought into them the center of gravity is not changed significantly. The consequence of this conception, which is still common today, was that only very short filters, essentially only filter disks, could be used.

The object of the present invention was to provide a method and a device for its implementation conceive that allows mouthpieces that are relatively long and that change the center of gravity decisively To provide filters and still have the option of attaching the filter to the cigarillo to be able to carry out the usual machines.

The method according to the invention is characterized in that the filter insert is only then introduced into the mouthpiece if it is in the magazine channel.

Pie device suitable for carrying out the method is in turn characterized in that in the cycle of the movement of the mouthpiece in the magazine channel with a intermittently effective compressed air source connected insert head with the. Dog piece is brought into a communicating connection.

The following is an example embodiment of the

sen procedure described, wherein in the p βίη embodiment of the device according to the invention dai'gestel.lt is. It shows;

The mouthpieces 2 located in a conveyor vibrator 1 are pushed by the vibrator into a magazine channel 3, whereby the corresponding center of gravity of the mouthpieces adjusts them with the opening k for receiving the cigarillo upwards in the relevant channel. The magazine channel is formed by the upper guides 5 and the lower guides 6, the inner surfaces of which are arranged at such a distance from one another that the upright mouthpieces 2 find space between them. A string 8 or 9 is stretched around two pairs of vertically positioned, rotatably mounted rollers 7, each of which is placed over two deflection rollers 10 and 11 and wraps around a drive roller 12. The lateral distance between adjacent rollers 7 is selected so that the respective inner strand of each string rests against the outer surface of the mouthpieces 2 located in the magazine channel 3, so that when the two strings are driven in opposite directions, the mouthpieces 2 move in the magazine channel 3 he follows. The bottom of the magazine

channel 3 is also through pulleys 13 of a drive roller her driven belt 14 is formed. on In this way, the mouthpieces 2 lined up in the magazine channel 3 are turned away from the conveyor vibrator 1 in the magazine channel 3 the filter insert system 15 moved to.

The filter inserts 16 also reach a magazine 18 via a conveying vibrator 17, from which they are brought into the clearance of a compressed air line 21 in a manner not shown by a slide 20 actuated by the lever 19. This compressed air line includes the nozzle 22, which is connected to an intermittently active pressure air source and is controlled by the switch 23. The filter insert 16 held in the slide 20 is blown into the hose line 2k , which is attached to the as a sleeve with lateral Luftdurchtrittsoffnurigen formed insert head 25 is connected. The insertion head is firmly connected to the carrier 26, which is arranged identically on two guide rods 27 and is subject to the action of two return springs. A compression spring 29 is supported against the carrier 26 and against the drive bar 30, the latter also being guided on the rods 27 and cooperating with the actuating fork 31.

Whenever a mouthpiece 2 of the magazine channel 3 is located in the axis of the insertion head 25 and a mouthpiece 2, provided with a filter insert 16, has been ^{pushed into a recess 1} IO of the ratchet wheel ^ l beforehand, the actuating fork is over the cam 32, the cam lever 33, the transmission rod 3 ¹ J and the support 65 pressed down, whereby, as soon as the spring 29 has reached a certain tension, this movement is transmitted to the carrier 26 and thus to the insertion head 25 until this last resiliently against the edge the mouthpiece opening k is present and in this way connects this mouthpiece opening with the hose line 2 ^{1 I.} Same-

A blast of compressed air is now given into the hose line 24 by means of the switch 23, whereby the -from the slide 20 lifted filter insert passes through the hose line and the insert head 25 into the mouthpiece opening 4. After the blast of compressed air, the fork 31 is back up and through the Return springs 28 of the carrier 26 and the insertion head 25 returned to the starting position. With the carrier 26 is a after connected below protruding plunger 35, which is arranged at such a distance from the insertion head 25 that it is at its Downward movement each enters the opening of the front mouthpiece and the blown filter insert up to the bottom of the mouthpiece opening 4 presses down.

At the end of the magazine channel 3, each mouthpiece is through the respective rear in a given by the stop plate 36 end position outside of the magazine channel where the relevant The mouthpiece enters a socket 38 formed by two pairs of lateral springs 37. Connected to support 65 is the ram 39, which is subjected to an upward and downward movement in the same cycle as the fork 31. This ram 39 now pushes the mouthpiece located in the enposition given by the stop plate 36 in its downward movement 2 from the socket 38 into one of the four recesses 40 of a holding wheel 41, where the mouthpiece 2 is secured by a clamp 42 is being held. As soon as the plunger 39 has reached its upper starting position again, the ratchet wheel 41 will not continue through control means shown rotated counterclockwise by 90 °, whereby the relevant recess 40 together with the therein The mouthpiece held in position reaches the area of the test system 43, which essentially consists of a clamp 44 horizontally displaceable and under the action of a spring 45 rod 46 at the front end of a sensor 47 and two two-armed levers 49 pivotable about the same axis of rotation 48 are pivotably arranged, the two rear levers

Arms are connected to one another by closing spring 50, while the ends of the other arms are designed as' clamping jaws 57 and together form a bracket 56. The pivoting the lever ^ 9 takes place by means of the actuating lever which can be pivoted between two stops 51 and 52 53, which over the lever piece 5 ^ and which at each of its ends arranged rollers 55 acts on the rear arms of the two-armed lever * »9.

With the clamp 56 open, the rod k6 is resiliently pushed forward by control means (not shown). If the filter insert 16 is in the mouthpiece 2, does the feeler 4 strike? in such a position of the rod HS on this filter insert 16 that the rod movement comes to a standstill before the actuating lever 53 strikes the stop 52. In the other case, the rod 56 continues its movement and the clamp 56 is closed by the impact of the actuating lever 53 on the stop 52. The clamping jaws 57 grip the mouthpiece 2 and pull it out of the relevant recess ² IQ of the indexing wheel ¹ H as far as the ejector 66 when the rod 6 moves back. In the course of the further backward movement, the actuating lever 53 strikes the stop 51, whereupon the clamp 56 is opened again, the clamping jaws 57 release the extracted mouthpiece 2 and allow it to fall into the container 56.

The mouthpiece 2, which is provided with a filter insert, reaches the area of the next time the indexing wheel * J1 is turned only schematically indicated and driven by the eccentric 59 device 60 for applying the adhesive and then into the end position in which the glue provided mouthpiece 2 through the rail 61 on the side of the concern

109884/1054

the recess ¹ IO of the ratchet wheel ¹ U. is ejected and brought into the area of a gripper 62 which places the mouthpiece 2 on a cigarillo 63 in a manner not shown any further.
