DE1155702B - Revolving device in filter cigarette machines for wrapping connecting plates - Google Patents

Description

The invention relates to a revolving device in filter cigarette machines for wrapping around of connecting sheets around the joints of cigarettes and filter plugs Groups, such as a winding drum, on which the groups with the connecting leaflets attached deposited, held and rolled, with one arranged outside the winding drum stationary, inherently rigid counter-rolling surface.

Devices with movable, in particular circumferential, counter-rolling surfaces are also known, which consist of circumferential bands and are thus flexible, but are stationary in relation to each other Counter-rolling surfaces have not been able to prevail, because it is understandable that this involves winding around the connecting leaflets are not quite so because of the resilience of the circumferential mating surface can take place reliably or evenly, as in the case of stationary, inherently rigid counter-surfaces. Well achieved one has a good effect with stationary counter-rolling surfaces at a certain low to be specified Pressure that arises from the fact that the distance between the counter-rolling surface and the surface of the Winding drum is about 0.1 mm smaller than the diameter of the groups. But this distance has the disadvantage that out-of-round filters are not rolled with certainty and a shifting of the leaflet and the filter can occur.

If the pressure is increased, safe rolling is guaranteed, but the Filter deformed too much during rolling, which in turn causes wrinkling of the filter wrap paper favored, whereby air pockets can arise. These disadvantages are in accordance with the invention fixed by the fact that the counter-rolling surface to adapt to the diameter of each of the cigarettes and filter plugs rolling through under it, resiliently resilient against the rolling pressure is arranged.

It is true that in a known rotating device for winding around connecting leaves Rolling rollers acting as counter-rolling surfaces known, which are radially closed within a winding drum these are movable, but the guide rollers assigned to the rolling rollers roll on a cam track away. These counter-rolling surfaces are not so flexible, but they are inevitably in guided by a train. The counter-rolling surfaces formed by the rolling rollers are therefore only in one arranged movably by the curved path, which is independent of the diameter Revolving device

the filter or cigarette is, while the stationary counter-rolling surface according to the invention has the diameter the cigarette or filter is arranged in a flexible manner as a function.

In a preferred embodiment of the invention, the counter-rolling surface is designed as a one-armed lever and the spring pressure adjustable.

An exemplary embodiment of the invention is shown schematically in the drawing. The drawing shows a partial side view of an already proposed one which does not belong to the invention Winding drum 1 with over the entire width of the winding drum as a limitation for the taxiway serving webs 7, which are attached to the front side of the drum arranged lever trays 8. the Lever arms 8 are arranged with their free ends on an axially parallel in the winding drum 1 Shaft 9 attached. Fixed cam disks 10 are also located on the end faces of the winding drum arranged. The shafts 9 of the adjustably attached control arms 11 have guide rollers 12 at their free ends on, which is drawn to the cam disks 10 by springs 13 attached to the links 11 will.

According to the invention, the required distance from the circumferential surface of the winding drum 1 is now arranged counter-rolling surface 23 pivotable in a stationary bearing 24. On the counter-rolling surface 23

a spring 30 acts, the pressure of which can be adjusted by means of an adjusting screw 31.

The operation of the device is as follows:
The winding drum conveys the connecting sheet with the groups adhering to it into the area of the counter-rolling surface 23. The counter-rolling surface 23 is now pivoted in accordance with the diameter of the group. The required rolling pressure is maintained by the spring 30, which ensures that the counter-rolling surface remains in contact with the group.

The resiliently flexible counter-rolling surface is particularly in the case of that shown in the exemplary embodiment Winding drum 1 with pivotable webs 7 is important because here the group is in contact with the subsequent web is brought and desirably with a proper pressure on this Rests. The spring is arranged in such a way that the spring pressure is reduced at the end of the rolling process, whereby a small slippage of the group is possible. This also allows you to be precise Do not measure the length of the counter-rolling surface 23.
