Description

GERMAN

For the manufacture of filter mouthpiece cigarettes, as is known, filter plugs are required which, since they are difficult to pack and just as difficult in their finished usable length because of their short length are to drive in the filter cigarette manufacturing machine, traded in stick form and only on the Manufacturing machine can be cut to length. So filter rods are made from which rods are cut whose length is a multiple of the useful length of the filter plug.

Even if a filter rod as such does not represent a value of importance, the large quantities of sticks that the growing demand for filter cigarettes requires, the demand for one Machine for counting isolated sticks and filling into one appropriate Behälit-niis to ensure that the For example, the customer receives a thousand filter rods in a controlled and perfectly packaged manner.

In itself, counting and filling machines for cigarettes are with a storage container and partially through Conveyor drums formed feed channels for the subsequently on conveyor belts in counting or filling rows known to be deposited, cigarettes to be pushed out by plunger. There are the conveyor drums provided with grooves on its circumference so that only as many cigarettes can be conveyed as it allows the number of revolutions of the grooved drums. In addition, each must be above each to be ejected Row of cigarettes before a new row slipped from the storage container without external intervention the next row can be ejected. The ejection speed is therefore limited, which is why it has already been suggested that the layers of cigarettes should alternate out of the chamber on both sides eject into intermediate container.

In ¹ of the study of the movement sequence in such a counting and filling machine for filter rods is to be considered that on the one hand the capacity of the machine is given by the exit velocity of the filter rods from the two Magazinauslässen and the other for the removal of the filter rods from the magazine channel only those Time is available in which the tappets release the conveyor belt for refilling the row of rods to be ejected when they decrease. The object of the invention is therefore to lay as many filter rods as possible next to each other for ejection in this short time, and this is achieved according to the invention that the unprofiled outer surface of the continuously rotating conveyor drum forms one wall of the feed channel, under which the conveyor belt, which is accelerated to the conveyor drum jacket, also forms Arranged over its end stop for the filter rods and also over the conveyor belt over the length of the counting and filling machine for filter rods

Counting series of extending plungers that can be moved transversely to the conveyor belt for axial pushing out the filter rod row is arranged.

It is thereby achieved that during the ejection of a filter rod row in the magazine channel rows of rods can be formed at least of such a length as to refill the discharge channels are necessary by using the filter rods

² S of the endlessly rotating belts are fed in accelerated under the effect of the slip existing between the drum circumference and the row of bars forming in the feed channel.

In order to improve the performance of the device even further, the rod magazine can be advantageous Counter-rotating conveyor drums with two feed channels for the two counter-rotating conveyor belts to be deposited rods be provided in a symmetrical arrangement.

Such a device is shown schematically in the drawing using an exemplary embodiment, namely shows

1 shows a section through the device, the ejection device for the rows of filter rods not being drawn for the sake of clarity, and
Fig. 2 is a plan view of the plunger.
Below a storage container 1 there are two conveyor drums 2 α and 3 a rotating in opposite directions in the direction of the arrow, their non-profiled ones

+5 outer surfaces that form a movable wall of a feed channel that runs concentrically to the drum. The filter rods S , which are also conveyed in the direction of the arrow by the conveyor drums 2 a and 3 a in the feed channels 2 and 3, pass below the conveyor drums 2 α and 3 σ in rows in horizontal channels, the lower channel wall of which is passed through two counter-rotating endless conveyor belts 4 and 5 and their ceiling a rigid mating surface 6 is formed. These two channels become the two rows of bars

S ₁ axially by means of a pusher device 7 shown in Fig. 2 into the layers ^ ₁ , that is pushed into a packaging container, not shown, which gradually decreases by .das the measure of the row thickness. ■ '■' ■■ ';, . } <

After the plunger 7 has returned from its ejection position 7 'to the position shown in FIG. 2 and has released the horizontal channels, the two rows of rods J ^ _{1 are immediately recreated by means of the conveyor drums 2 α and 3 a and the conveyor belts 4 and 5} of, for example, ten filter rods each, which creates gaps in the feed channels 2 and 3, which are refilled both during the ejection movement of the plunger 7 and during the formation of the rows of rods S ₁ by the conveyor drums 2 α and 3 a rotating steadily and quickly and Uninterrupted feed sticks from the storage chamber 1. The front filter rods 5 ″ lie against the two side walls of the plunger 7. The drawing shows the state in which the two rows of rods S _{1 are} ejected and the rows of rods vS are formed in the two feed channels 2 and 3 during this same time, with so the two conveyor drums 2 α and 3 a continue to run at the appropriate speed, while the two conveyor belts 4 and 5 stand still.

In addition, the rods S do not perform any rotational movement when conveying through the feed channels 2 and 3, since they are prevented from doing so by the friction on the stationary channel walls.

There is therefore in continuous circulation of the conveyor drums 2 α and 3 α and constant conveying the rods 6 'from the storage container 1 in the feed channels 2 and 3, a batch accelerated conveying the bar rows ^ _1, whereby the above-mentioned power increase of the device is achieved.

It should not go unmentioned that such funding is only possible if the Material from which the filter rods are made, the Be

can cope with stress, especially those caused by friction.
