Definitions

• the invention relates to a device for connecting axially aligned cigarettes and filter plugs assembled in groups by wrapping glued connecting sheets around areas of the cigarettes adjoining the abutting points and around the filter plugs, with a moving rolling surface, which together with a counter-rolling surface forms a rolling channel for rolling of the groups and for the winding around of the connecting leaflets caused thereby, a starting bar being arranged in the entrance area of the rolling channel for the forced and simultaneous initiation of the rolling movement of the groups.
• the connecting leaflet can be long enough to cover not only the filter plug but also the cigarettes.
• cigarettes and filter plugs are first put together in axially aligned groups, which usually each consist of two external cigarettes with a filter plug of twice the length of use arranged in the center.
• a glued connecting sheet is attached to the filter plug and the areas of the cigarettes of a group adjacent to the joints between the filter plug and cigarettes, and the group is fed to a rolling channel.
• This essentially consists of a moving rolling surface, which is generally designed as a surface section of a rotatable rolling drum, and a stationary or moving counter-rolling surface. The distance between the rolling surface and counter-rolling surface is somewhat less than the diameter of cigarettes and filter plugs, so that a group conveyed on the rolling drum performs a rolling movement in the rolling channel.
• filter cigarettes can also be formed from single cigarettes with adjacent filter plugs of simple use length, a central cut through the filter plug following the rolling and wrapping process being omitted.
• start bar which is arranged in a stationary manner in the entrance area of the rolling channel and protrudes beyond the actual rolling surface and the surface of the feed conveyor.
• the object of the invention is to improve the function of the start bar, especially when oval cigarettes and filter plugs are rolled in the roll channel.
• the start bar on its side facing the rolling channel, has a transition leading the groups to the rolling channel.
• the transition is designed as a continuous guide surface which gently guides the groups to the level of the rolling channel after rolling.
• the guide surface is advantageously rounded.
• it can have fine intersecting grooves (radiation grooves) which make the surfaces of the guide easier to grip, which increases the accuracy of the guidance of the cigarettes.
• the starting bar can be jagged or wavy on its outer line of action.
• the start bar of the invention is particularly suitable for the arrangement in front of rolling channels, which are designed for rolling groups of oval cigarettes and filter plugs and whose rolling and counter-rolling surfaces are designed in a corrugated manner.
• the rolling surface can have fine intersecting grooves (scattering grooves).
• grooves of a family of at least approximately parallel grooves advantageously intersect with the grooves of at least one family of likewise at least approximately parallel grooves.
• Grooves of at least one coulter can then have an angle to the longitudinal axes of the cigarette.
• the counter-rolling surface can also be provided with radiation grooves of the type described above.
• the depth of the radiation grooves according to the invention is preferably 0.3 mm to 1.2 mm, e.g. B. about 0.5 mm.
• the advantage according to the device according to the invention is that the groups of cigarettes and filter plugs do not leave the bar abruptly, but gently, after rolling on from the start bar, after which they are gently guided to the rolling channel on a continuous surface.
• the invention is particularly suitable when rolling oval cigarettes and filter plugs that do not fall off the start bar, but are gently guided downwards.
• FIG. 1 shows a schematic representation of a known rolling device for oval cigarettes
• FIG. 2 shows an enlarged illustration of part of FIG. 1,
• FIG. 3 shows a surface of a rolling device according to the invention on a reduced scale
• FIG. 3a shows a detail of a roller drum according to FIG. 3,
• FIG. 4 shows a start bar for a rolling device according to FIG. 3,
• FIG. 5 shows a variant of the start bar for a rolling device according to FIG. 3.
• FIGS. 1 and 2 show a rolling device 30, known from DE-A1-195 07 395, of a filter attachment machine (not shown in more detail) for wrapping oval cigarette filter plug-cigarette groups 52 with glued onto the topping paper sheets 53, one of which is shown in FIG. 2 for illustration is. The remaining leaflets are not shown for the sake of simplicity and clarity.
• the rolling device 30 consists of the rotating roller drum 29 and the rolling surface 62 as well as the stationary rolling hand 31 with a counter-rolling surface 54 running adjacent to the rolling surface of the rolling drum.
• the rolling drum 29 has a hollow cylindrical drum body 56 which is connected to a stationary control body 57 not shown vacuum source connected control slots 58 revolves in its outer peripheral surface.
• the circumferential surface of the roller drum 29 is designed as a rolling surface 62, in which the flat-shaped holding troughs 59 are integrated.
• the roller drum rotates in the direction of arrow 63.
• the rolling hand 31 having the counter-rolling surface 54 is attached to a parallel lever drive 64 (not described in more detail) which, when required, pivots it away from the rolling drum 29 by means of a drive 66, for example a piston-cylinder unit, and keeps it in its functional position during operation.
• the rolling surface 62 of the rolling drum 29 and the counter-rolling surface 54 have a wave profile. This results in a rolling channel 67 between the surface 62 of the rolling drum 29 and the counter-rolling surface 54.
• the rolling surface 62 of the rolling drum 29 and the counter-rolling surface 54 are adapted to the non-circular shape of the article groups 52 rolling in the rolling channel 67.
• the wave profiles are shaped so that the article groups 52 can roll when rolling in the rolling channel 67 on the moving rolling surface 62 of the rolling drum and the stationary counter-rolling surface 54, the central axis of the article groups simultaneously being on an arc 68 around the axis 69 the roller drum 29 moves.
• This design of the rolling surface 62 and the counter-rolling surface 54 thus has the effect that the center of gravity of the article groups 52 can move on a continuous circular path through the rolling channel 67 while the non-round article groups are being rolled.
• the topping paper sheet 53 previously attached to the article groups is wound around the joints of the axially suitably arranged components and connects these to double-filter cigarettes 71.
• an axially parallel starting bar 72 is arranged at the beginning of the counter-rolling surface 54, which pushes the article groups out of their holding troughs, simultaneously aligns them axially and starts the rolling process.
• the control slot 58 ends in the stationary control body, so that the suction air effect in the holding trough 59 in question is interrupted. This enables undisturbed and gentle rolling of the article groups.
• the wave profile of the counter-rolling surface is repeated at least once in the conveying direction for a complete revolution of the article group about its central axis. This means that the profile sections from Wellenberg to Wellenberg 54a-g are essentially identical.
• Each of these profile sections from Wellenberg to Wellenberg allows the article group to be rolled over by 180 °.
• four substantially identical profile sections are provided in succession on the counter-rolling surface, which comprise the area from the wave crest 54a to the wave crest 54e.
• Six such identical profile sections are required for rewinding three times, which in the example shown in FIG. 2 extend over the wave crests 54a-g.
• FIG. 3 shows a rolling drum 29 with a rolling surface 62 of the shape shown in FIGS. 1 and 2, the rolling surface of which additionally has fine intersecting grooves, so-called radiation grooves.
• the grooves of a group of at least approximately parallel grooves advantageously intersect with the grooves of at least one further group of likewise at least approximately parallel grooves.
• the grooves of at least one group are at an angle to the cigarette axes.
• the scoring of a coulter can run parallel to the cigarette axes, while the scoring of at least one further coulter run at an angle to the cigarette axes.
• the intersecting grooves cover the rolling surfaces like a net, so that there are elevations with very small surfaces between the grooves, which are very easy to grip and allow the cigarettes to roll very well and without slippage. Two sets of intersecting grooves can also be used, none of which contain grooves that are parallel to the cigarette axes.
• the depth of the radiation grooves is preferably between 0.3 to 1.2 mm, eg. B. at about 0.5 mm.
• the forces on the cigarettes can be lower compared to the usual rolling channels, which reduces the loss of hardness of the cigarettes.
• the rolling surface 62 has holding troughs 59, not shown, in FIG. 2.
• the counter-rolling surface 54 on the rolling hand 31 can advantageously also be provided with radiation grooves corresponding to the rolling surface 62, which further increase the grip of the boundary surfaces 62 and 54 of the rolling channel 67.
• the advantage of the lower load on the article groups and the resultant lower loss of hardness also occurs in the case of round cigarettes which are rolled in rolling channels, the rolling surfaces and counter-rolling surfaces of which are cylindrical. Also on such rolling surfaces and / or counter-rolling surfaces intersecting groups of radiation striations can be applied, which cover the surfaces like a net.
• the start bar 72 arranged at the beginning of the rolling channel 67 advantageously has a transition 72a leading the groups to the rolling channel on its side facing the rolling channel 67.
• This transition can be designed as a guide surface, which is formed by grinding the starting bar 72, and which is advantageously also provided with radiation grooves. These striations of radiation can also form intersecting sheets which cover the surface 72a in a network-like manner. They increase the grip of the transition surfaces, which is particularly advantageous for non-round cigarettes, such as oval cigarettes, because the risk of tipping is reduced.
• the outer line of action of the start bar 72 may have a prong or wave shape 72b or 72c.
• the last-mentioned configurations of the start bar 72 with guide surfaces 72a and surfaces 72b, 72c according to the invention are also advantageous not only for oval cigarettes but also for round cigarettes.
