Description

GERMAN

In the cigarette industry it is known to convey the tobacco on a conveyor belt through one behind the other Role set. ”, Xvi lead, which one in the direction of the funder Form tapering cross-section, so that the finely cut initially lying loosely on the conveyor belt Tobacco is pressed into a continuous strand. ;. _ ...... .. ·. -.

On the other hand, tobacco wraps such as those used for the production of cigars, cheroots and cigarillos were used are, until now, pressed by hand into wooden press frames by inserting them individually. This way of working is cumbersome and time consuming. It has the further disadvantage that the rectangular cross-section of the coil is immutable, d. H. can only be achieved by reworking the wooden press frame. the Pressing time is at least 12 hours; the wooden frames are stacked on top of each other and become pressed with clamps. The space and workload is considerable. Even edge pressure can only be made possible by correct centering of the roll when it is inserted into the wooden frame which in turn is cumbersome and time-consuming. The wraps have to be taken out one by one by hand Wooden press frames are taken.

It is also known to divide the winding into individual pieces arranged on rotating conveyors To press molds. Although this already brought a certain amount of movement into the workflow is, there are still some of the peculiarities mentioned here.

The invention avoids these peculiarities in that the tobacco rolls from a stack one after the other brought into a coaxial position and in continuous movement through transverse to the winding axis, gradually increasing pressing pressure are formed in the direction of movement of the roll.

A compression molding device is expediently used to carry out this process of tobacco wrappings which are scarred by a funnel with stacking shaft and ejection device for the lap downstream, with in Direction of movement of the winding movable and tapered boundaries provided channel.

Preferably the cross section of the channel is rectangular or square; the boundaries of the channel are preferably rounded at the channel edges in such a way that the boundaries appear convex as a whole towards the channel. What is achieved in this way is that when the molding pressure is exerted, the tobacco leaves have a certain expansion possibility at the edges and are not compressed. Otherwise, a compression could lead to the destruction of the tobacco leaves.
In one embodiment, the channel is through the method and apparatus
for compression molding of tobacco rolls
for cigars, cheroots and cigarillos

Applicant:

Burger Söhne Schweizerstumpenfabriken, Emmendingen (Bad.)

Karl Heinrich Wirthgen, Freiburg (ßxeisgau),
has been named as the inventor.

a plurality of sequentially arranged sets of press and conveyor rollers are formed, with the axes the roles of one. The set. Expediently each lie in one plane and the one formed by the roles clear passage cross-section decreases from set to set.

Each set of rollers advantageously consists of four rollers offset from one another by 90 °. Multiple roles can be combined into groups. Preferably one will be on two opposite sides of the tobacco roll adjacent rollers, expediently the rollers rotatable about a horizontal axis, Connect them with each other with a strap, such as a rubber band. One roll each by rubber bands In this case, roles connected to one another are expediently common to all role groups Drive connected; the other rollers in each roller group can move freely without a drive be. The axes of at least two rollers are expediently displaceable parallel to themselves, see above that the cross-section of the channel can be changed by moving them.

For the introduction of the tobacco roll, a prismatic, more funnel-shaped in its cross-section. Container provided, which in its upper, enlarged Part accommodates a variety of tobacco rolls and is dimensioned in its tapered part so that only one winding at a time can pass through this tapered part; the Γ conclusion of the rejuvenated Partly lies in such a plane that the tobacco rolls resting on it are in axial alignment with it located on the canal; on the end face of the prismatic container facing the channel, the latter has open an opening, through the one at the bottom, with

tobacco packets aligned with the channel enters the channel; Finally, a feed mechanism is provided, which pushes this tobacco wrap into the channel.

According to one embodiment, the feed member is a stamp which is on the of the tapering Channel remote end face through an opening of the funnel container enters this and by a cam drive with a frequency matched to the conveying speed of the channel is moved back and forth.

The converging side walls of the hopper are connected to a vibrating drive.

In a practical embodiment, there are several channels, each with an associated funnel container arranged side by side, the drive rollers of each roller group on a common drive shaft sit, the feed ram are simultaneously advanced by a common cam drive and the vibrating plates are connected to a common vibrating drive.

The drawing shows an embodiment of the invention. It shows

Fig. 1 is a plan view of the channel formed by rollers in section along the line I-I in Fig. 4,

2 shows the mutual arrangement of the rollers of a roller set,

3 shows a cross section through the introduction funnel,

FIG. 4 shows a longitudinal section of the introduction funnel along the line IV-IV in FIG. 3.

1 shows several sets of rollers 12 combined to form a roller group 10. Each of these sets of rollers consists of four rollers, namely two rollers 12a and 12a rotatable about horizontal axes and two rotatable rollers each about vertical axes Rolls 14 a and 14 b. The rollers of group 10, which are rotatable about the horizontal axis, are connected to one another by a belt 16 or 18, respectively. The rollers are convex on their circumferential surfaces and are arranged with respect to one another in such a way that they result in a cushion-shaped cross section, that is to say formed by inwardly convex sides. The clear passage is formed on two of its sides by the circumferential surfaces of two shafts, on the other two side surfaces by the rubber bands 16 and 18, respectively, resting on the circumferential surfaces of the rollers.

One of the rollers 12 a and 12 & is arranged on a drive shaft 20 α and 20 b , which carry drive sprockets 22 a and 22 & respectively. The chain wheels 20a and 20 & of the various roller groups are each connected to one another by a common chain 24α or 24 &.

The clear passage cross-sections of the various roller groups and, if necessary, also the individual roller sets, the winding decreases in the conveying direction.

A prismatic container 26 with a funnel-shaped cross section is provided for introducing the winding into the roller channel. This prismatic body accommodates a multiplicity of tobacco rolls 28 in its enlarged upper part. In its lower, tapered section (at 30), the width of the funnel-shaped container is dimensioned so that only one winding can pass through this part of the funnel. The lower end wall 32 of the funnel container is at such a level that the bottom tobacco rolls of the funnel container siah resting on this end wall are in axial alignment with the channel (see FIG. 4). In the end face of the funnel container, an opening 36 is provided through which the bottom tobacco roll in each case can be pushed out towards the channel. A further opening is provided at 40 at a corresponding point in the other end wall 38. A thrust ram 42 can enter the funnel container through this opening and push the respective lowermost tobacco roll into the channel. The thrust ram 42 moves back and forth at a frequency which is adapted to the conveying speed of the channel. The amplitude of the reciprocating movement of the Schufo stamp is dimensioned so that the tobacco roll penetrates far enough into the channel to be carried along by the driven rollers, ie by the rollers a and 12 b.

To prevent clogging of the funnel, the converging side walls 44, 46 of the Funnel designed as vibrating plates, which are sobwingbar about pivot points 48 and 50 and from one Eccentric 52 can be pivoted under push rods 54 through a small angle.
