Description

TECHNICAL FIELD OF THE INVENTION The present invention relates to an apparatus for dividing and pretreating tobacco.

[Technical background of the invention and its problems]

In the tobacco industry, compressed bales of tobacco leaves (
caaea, bales, '! Tahhog@h
Before the ead@) can be handled, it is necessary to pre-treat them (pre-conditioning), and this treatment results in tobacco leaf content. Pretreatment softens the tobacco and reduces the occurrence of deterioration during subsequent operations for tobacco manufacturing. The next operation that is usually carried out after pre-treatment is to ensure that the increased moisture is sufficient to allow the tobacco leaves to be shredded.

Initial processing is usually done in a one-minute operation (batch operation), followed by a line operation, which is often carried out with rotating cylinders.

There are methods for the continuous unpacking and pre-treatment of compressed tobacco leaves, i.e. l), where the packaging of tobacco leaves is described, for example, in British Pat.
tθt3 No., l, /36.1132, Shi07 Shitat
JA issue and 2.04! Z070A, the tobacco leaf sections are then sent to a rotary divider (doffara) for processing;
23JI! In the tobacco method, the addition of moisture is carried out simultaneously with the unpacking operation; 3) After the tobacco pieces are made by dry cutting, There are methods such as I that are sent directly into the processing cylinder.

[Purpose of the invention]

It is an object of the invention to provide a device of the type with a pretreatment cylinder, in which dry cutting of the tobacco in a separate operation is obviated.

[Summary of the invention]

The present invention provides an apparatus for unpacking and pre-processing tobacco leaves, which comprises a substantially horizontal cylinder or an axis slightly inclined with respect to the horizontal. a cylinder rotating about its center, a feeding chamber placed at the artificial end of said cylinder, means placed in said chamber for dividing the tobacco placed in said feeding chamber, and for imparting high humidity to said feeding chamber; and means for conveying tobacco from the supply chamber into the cylinder.

Said means for dividing the tobacco comprises a number of upwardly projecting protrusions placed in the garden of said feeding chamber so as to be centered on axes that diverge in the direction of progress of the tobacco from said feeding chamber to said cylinder. The tobacco can be shaped so that the tobacco is divided between the tobacco leaves by the upper ifpi projection as it advances from the feeding chamber towards the cylinder. The means for conveying the tobacco from the supply chamber to the cylinder may be in the form of rams, conveyor belts or projections, which have driven wheels of wedge-shaped radial cross-section (i.e. in the form of a discus disc). obtain.

A bale of compressed tobacco leaves is placed with the tobacco leaves vertically and said bale is fed in the direction of its length;
In this way, the entire package is fed into a feeding chamber, said feeding chamber being of sufficient size to accommodate the entire package.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

The rotation processing (tempering) cylinder IO is placed in a housing IOA placed on a holding stand IOB, and is placed on a roller held on a holding frame 12. cylinder IO
The axis of the cylinder is tilted relative to the horizontal, and the tobacco advances along the cylinder as it rotates.

The cylinder io is equipped with a known drive means (not shown), a fan/J (J
Figure), and a water spray controlled to deliver a predetermined amount of water into the cylinder outside of the water content of the treated tobacco/4! However, since these means are well known in this technical field, detailed explanation is not considered necessary.

A fixed chamber (supply chamber) /j is located near the inlet end of the cylinder IO.
is set up in this room/! Inside there is placed a stand/A for holding the bales of tobacco leaves, and this stand 16 is placed in a group of places spread out over the garden in small spaces (Fig. 1). It has a wedge-shaped wheel 17. The number and dimensions of the wheels 17 are such that when the entire package is placed in the chamber 7.5, the wedge-shaped wheels protruding from the holding base will cause the package to split vertically along appropriate lines of tobacco leaves. I am scheduled to be busy. The package is thus divided, all of which are housed in a humid, warm conditioned air environment in the room is.

Attached to the inner surface of the cylinder io is a group of concentric rings 19 at the feed end, the rings 19 having integral inwardly directed pins (as shown) on their front faces. The diameter of the ring 19 gradually increases towards the outlet end of the cylinder. Said ring lt/I/'i is provided over a distance of 7.3 m from the outlet end of the cylinder. Downstream of the ring 19 is an internal ring-shaped wear plate (only one of which is shown).
is provided, followed by product lifting pins and paddles (
(not shown) is provided.

A package C of compressed tobacco leaves is placed vertically in a chamber i.
s, at which time the package is divided. Feeding from the empty IS into the cylinder 10 takes place by a conveyor belt n and a ram, 2.11C, and then the bales pass through a diverging concentric group of rings 19 with inward pins 20, during which The packaging consists essentially of the constituent parts of the tobacco leaf (
tissue components). The ejection rate of tobacco leaves from the cylinder 10 is highly controlled by the ring-shaped wear 21. At this time, the product is provided with a water spray to ensure the desired moisture content of the product being discharged.

The device has means for feeding into the chamber the parts of the package which have already been divided. This type is used for low flow applications.

FIG. 1 shows a conveyor nA1 for transporting the packages forward and a ram 2JA for transporting the packages laterally.

and a conveyor JJB is shown for feeding the packages forward again, which conveyor JJB can be moved vertically and placed on the same level as the conveyor, 22.

In the variant shown in FIG. 7, the dividing wheel has a plurality of angular projections (this is shown in plan view in FIG. 71). It is arranged to reciprocate in a horizontal plane and descend as the tobacco pieces are removed.

The front stop 31 for packing tobacco also lowers in synchronism with the divider 30. Processing air enters through openings 32.

In the modification shown in FIG. 2, a stand 35 is provided and the stand 3
! ;tI'i, lifting mechanism sent upwards (not shown)
It is raised by Further placed in the chamber is a band 36 with a number of horns, which successively removes layers of tobacco and conveys them into the cylinder 10. Alternatively, the tobacco is placed on a stationary table and the dividing band is fed downward.

The figure below shows yet another variant, in which a split ram made in the form of a bladed ram is used with a lifting platform 1, which is fed upwards. Alternatively, the tobacco is placed on a stationary table and the splitting ram is fed downward.

In the variant shown in Figure io, a split wheel hilt is used, and the wheel! j(fi, held on a frame (not shown) so that it can be lowered downwards. In this form,
Tobacco is fed into the chamber 15 in such a way that the tobacco leaves are placed transversely to the direction of movement of the tobacco in the cylinder. Ram t6 gradually feeds the divided tobacco into cylinder IO.

FIG. 11 shows a more narrow plan view. In this form, the bales of tobacco are fed onto the conveyor j, apparently multiple times in succession, towards the chamber 13, and the dividing and feeding of the tobacco takes place by means of a blade y at the leading end of the bales. As shown in Figure 1/a, the blades SO are each driven by a link mechanism (not shown) to move along a triangular action path, but they are driven to move along a rectangular action path. It is also possible to

〔Effect of the invention〕

The main advantages of the invention are as follows. That is, /) the splitting of the bales of tobacco leaves is carried out in an environment of high humidity process air; and /) spilled leaves and any debris created during the splitting of the bales are transported directly to the screw conveyor. 3) The whole package is processed (tempered); Cascading links /9 in the cylinder prevent excessive falling of the divided packages 2, etc.
