Description

Method and apparatus for loosening bales compressed Tobacco leaves The invention relates to a method for releasing in rectangular Compressed bale of compressed tobacco leaves, which is carried out after the tobacco bale have been subjected to a moisture treatment through which a certain flaking of the ball took place with the loosening of its structure.

The individual leaf layers used to be broken apart by hand and then, if necessary, fed to loosening machines, which also do not loosened Leaf components and foreign bodies due to the specific weight differences severed.

A number of mechanical dissolving processes have recently been developed but all of which are based on the principle of putting the bale in a first step to be broken down into layers, which are then subjected to a further dissolving treatment in a second step must be subjected.

The bales are preferably brought up to the peeling tools in close succession on a transport path, which is on both sides of a recess has arranged fixed supports for the bale, the recess in the counter to the direction of transport of the shaft revolving, in its path by a certain Dimension engaging peeling tools are arranged.

The axis of the shaft is adjustable in height to accommodate the layer thickness To be able to adjust the peeling process; this is usually only a few millimeters. This will make the goal of getting as single leaves as possible from the underside of the bale to push off or to solve, achieved in an advantageous manner.

Since each peeling roller only decreases a correspondingly small layer thickness, is preferably the required number of peeling rollers at suitable intervals arranged one behind the other, with the lateral plate-shaped edging of the following peeling roller, which the bale during support the peeling process, taking into account the progress of this process will.

In the figures is a schematic with omission of all for the Understanding of the invention dispensable details a part of a device to carry out the new process, using rotating peeling tools, shown.

The tobacco bale a is transported by the transport device, not shown pushed over the table top b shown in the figure on the left. Between this and the adjoining plate c (in the figure on the right) there is a recess d of about 120 mm width according to the embodiment, within which the peeling device e, the four striking arms arranged on a shaft h according to the exemplary embodiment f has truncated edges g, in the direction of arrow A, against the transport device B of the bale rotates.

The bales pass the recess in direct succession, whereby due to the action of the rotating peeling organs a layer thickness of according to the embodiment 10 mm of the bottom layer of the bale is not just cut off but also the leaves that form them are isolated without any damage will. The bale is then transferred to the following peeling device via the adjoining plate c fed.

There is only one assistant to operate the entire system necessary.

In such a two-stage process, apart from the disadvantages, which are justified as such in the two-stage working method, the tobacco leaves exposed to a considerable extent to the risk of damage.

The one-step process according to the invention which avoids these disadvantages is basically that the tobacco leaves from the moistened bales in thin layers, each a few millimeters thick, peeled off and thereby the leaves be separated even in the most gentle way.

The tools that cause this peeling are considered to be strip-like Body made of wood, metal or plastic, the effective edges of which are truncated and which are either rotating on a shaft or on an endless belt are arranged. The peeling of the layers from the bale can e.g. B. done progressively from top to bottom, the peeling tools on which the bales move past, under a certain pressure on each act on the top layer of the bale. However, the bale is expedient from below progressing upwards, with the action of the peeling tools on his each lowest layer, worked off, whereby the dead weight of the bale is the required Supply pressure to the peeling tools.

Claims (6)

CLAIMS: 1. A method for dissolving compressed into bales of tobacco leaves with separation of layers in the direction of sheet documents, data carried in that the tobacco leaves in thin layers of a few millimeters thickness are peeled off from the tobacco bale, which are occasionally simultaneously. 2. Device for performing the method according to claim 1, characterized by a transport path for the bales (a), which are arranged on both sides of a recess (d) has fixed supports (b, c) for the bale, in the opposite direction the transport direction of the bales revolving, engaging in their path by a small amount Peeling devices (e) are housed. 3. Apparatus according to claim 2, characterized characterized in that the peeling tools as a strip-like body (f) made of wood, metal or plastic are formed, the effective edges (g) are truncated. 4th Device according to Claims 2 and 3, characterized in that the altitude the axis around which the peeling tools rotate is adjustable. 5. Device according to claims 2 to 4, characterized in that several peeling devices are connected in series, which the bales with each decrease of a Process the leaf layer. 6. Device according to claims 2 to 5, characterized by an endless belt that is moved below the bale and at right angles to the Having arranged in the feed direction strip-like peeling tools.
