Description

Leaf tobacco deboning device

The present invention relates to a leaf tobacco deboning and separating apparatus for separating leaf tobacco into lamina and middle bone by removing the middle bone from the leaf tobacco.

In the tobacco raw material plant, leaf tobacco after harvest is deboned (threshing processing) of the inner bone by an bone removing device, and is separated into a lamina (meat) and an inner bone. In the threshing process, it is required to take out a lamina as large as possible and to accelerate the processing speed. For this reason, the leaf tobacco is conditioned to a high moisture state and treated to a flexible state (a state in which it is difficult to be crushed by an external force), thereafter a slushing treatment is performed, and a slushing treatment is optionally subjected to a drying treatment. , Will be packed finally.

Patent Document 1 discloses a bone removing apparatus in which two threading gears having scraping teeth attached to the circumferential surface of a rotating drum are attached to the same rotation shaft. In this apparatus, leaf tobacco supplied from the raw material inlet into the basket can be taken out from the outlet after the threshing process is performed by the respective threshing gears.
Further, Patent Document 2 discloses a method and an apparatus for wind separation of shredded stem material of leaf tobacco by a first gas flow and a second gas flow in a housing.

The threading unit 8 includes a rotating drum 32, a first servomotor 34, and a basket 36. The rotary drum 32 is rotatably accommodated in the casing 2 and a plurality of threshing teeth 38 are provided on the circumferential surface. As will be described in detail later, the shape and arrangement of the teeth 38 are determined according to the type and moisture content of the leaf tobacco used as the raw material.

The rotary shaft of the rotary drum 32 and the motor shaft of the first servomotor 34 are connected via the rotary belt 40, and the first servomotor 34 is electrically connected to the control unit 42. By changing the set rotational speed by the control unit 42, the rotational drum 32 is driven to be variable in rotational speed by the first servomotor 34. The basket 36 is in the shape of a downwardly convex curved plate, and is fixed to the lower side of the rotary drum 32 in the casing 2 in close proximity to the throttling teeth 38.

The basket 36 and the teeth teeth 38 are spaced apart from each other on the lower side of the rotary drum 32 with a predetermined gap (for example, 5 mm), and the basket 36 is perforated with a large number of holes 44. Also, the basket 36 and the rotating drum 32 are detachably attached to the housing 6 by opening the cover 4. A shielding plate 46 is rotatably fixed to the cover 4 via a lever 48 at the upper right of the basket 36.

The lamina and the mid bone scraped up by the squeezing teeth 38 along the lower surface of the basket 36 are prevented from scattering into the cover 4 by the shielding plate 46. Nevertheless, the lamina and mid bone scattered in the cover 4 near the basket 36 and in the upper part of the casing 2 can be easily cleaned by operating the lever 48 to open the shielding plate 46 in a direction away from the basket 36.

The air separation unit 10 is formed below the basket 36 in the casing 2 and includes a blower 50 and a second servomotor 52. A discharge port 22 is positioned at the lower end of the wind separation unit 10, and a recovery port 24 is positioned at the right end of the wind separation unit 10. The blower 50 is provided on the left end side of the wind separation unit 10 as viewed in FIG. 1 and generates an air flow which flows above the discharge port 22 and is directed to the recovery port 24.

The blower 50 is, for example, a multi-blade blower such as a sirocco fan, and the rotation shaft of the blower 50 and the motor shaft of the second servomotor 52 are connected via a rotation belt 54. The second servomotor 52 is electrically connected to the control unit 42, and the blower 50 is driven by the second servomotor 52 so that the wind speed (air volume) can be varied by changing the set rotational speed by the control unit 42. That is, the control unit 42 can control the first and

second servomotors

34 and 52 individually.

In the casing 2, the first guide plate 56 and the second guide plate 58 are attached to the lower side of the basket 36, and the third guide plate 60 is attached to the lower side of the blower 50. The first guide plate 56 is provided at the lower left of the basket 36 and is in the shape of a bent plate, and is a part of the middle bone and lamina passage 62 which falls through the opening 44 of the basket 36 in the casing 2. And part of the flow path 64 of the air flow sent from the blower 50.

The second guide plate 58 is provided at the lower right of the basket 36, has a bent plate shape, and defines a part of the passage 62 in the casing 2. The third guide plate 60 is in the form of a bent plate and defines a part of the flow path 64 in the casing 2 and a part of the discharge path 66 of the middle bone leading to the exhaust port 22.

Here, a baffle plate 68 which forms the lower edge 24 a of the recovery port 24 of the lamina in the wind separation unit 10 and an adjustment mechanism 70 of the baffle plate 68 are provided in the bone removing apparatus 1 of the present embodiment. ing. The baffle plate 68 is inclined and extended from the lower left to the upper right in FIG. 1 and defines a part of the flow path 64 for guiding the lamina to the recovery port 24. The baffle plate 68 is formed by overlapping the upper side plate 68a and the lower side plate 68b, and the upper side plate 68a is disposed slidably with respect to the lower side plate 68b.

The adjusting mechanism 70 is composed of a thumb screw 72, an elongated hole 74, and a scale plate 76, and is provided on both side walls of the casing 2. The thumb screw 72 secures the baffle plate 68 to the side wall of the casing 2 such that the upper plate 68a can slide relative to the lower plate 68b and the baffle 68 can tilt. The long hole 74 is opened in the side wall of the casing 2 and has a long shape from the lower right to the upper left as viewed in FIG. 1, and the thumbscrew 72 is screwed. The scale plate 76 is attached to the side wall of the casing 2.

In the adjustment work of the baffle plate 68 by the adjustment mechanism 70, the upper plate 68a can slide relative to the lower plate 68b by loosening the head of the thumb screw 72 by hand. Thereby, expansion and contraction of the baffle plate 68 is permitted, and the opening area of the recovery port 24 can be changed by the movement of the lower edge 24 a. At this time, it is also possible to move the screw portion of the thumb screw 72 in the long hole 74, thereby allowing tilting of the baffle 68 around the thumb screw 72.

Since the baffle plate 68 divides a part of the flow path 64 of the air flow in the vicinity of the recovery port 24, the flow path 64 can be changed by the expansion and contraction and tilting of the baffle plate 68 described above. In the adjustment operation of the baffle plate 68, by confirming the scale described on the scale plate 76, the baffle plate 68 can be symmetrically fixed on the both side walls of the casing 2 as viewed in FIG. It can be made not to be fixed in the state which shifted in the front back direction seeing in FIG.

Hereinafter, with reference to FIG. 2, the aspect which isolate | separates a leaf tobacco into a lamina and a middle bone with the bone removal apparatus 1, discharges a middle bone, and collect | recovers lamina is demonstrated. In FIG. 2, only necessary parts are described in the description, and the other parts are omitted. First, the leaf tobacco T supplied from the supply port 16 to the threading unit 8 is pressed against the basket 36 by the throttling teeth 38 and rubbed along with the rotation of the rotary drum 32 in the direction of the arrow. Being separated into the middle bone B and the lamina L.

The separated inner bone B and the lamina L pass through the respective openings 44 of the basket 36 and fall to the wind separation unit 10 through the passage 62. In the wind separation unit 10, the relatively high density inner bone B falls from the discharge port 22 via the discharge passage 66 against the air flow 78 which is a region shown by a two-dot chain line in the figure by its own weight. On the other hand, the relatively low density lamina L flows through the flow path 64 formed in the air separation unit 10 and is carried out of the recovery port 24 on the air flow 78.

Here, the air flow 78 starts to decrease the wind speed of the air flow 78 bordering on the area turning point P formed at the lower end of the area with the expansion of the area. The area turning point P changes in accordance with the wind speed of the air flow 78 from the blower 50 set by the control unit 42. For example, the area conversion point P is changed to the area conversion point P1 higher than the area conversion point P when the wind speed of the air flow 78 increases. Such change of the area conversion point P is appropriately performed according to the type of leaf tobacco T, in particular, the density of the inner bone B and the lamina L, and the supply amount of leaf tobacco T.

Further, for example, as shown by a broken line in FIG. 2, by extending the baffle plate 68 in the arrow direction by the adjusting mechanism 70, the recovery port 24 shown by a two-dot chain line is shown by a dashed line. Opening area can be reduced. In this case, at the same time, the lower end of the area of the air flow 78 indicated by the two-dot chain line is changed to the position indicated by the broken line. Further, by tilting the baffle plate 68 as shown by the arrow by the adjusting mechanism 70, the opening area of the recovery port 24 and the position of the lower end of the area of the air flow 78 can be changed as in the case of extending and retracting the baffle plate 68. It is. It is also possible to change the area turning point P by the expansion and contraction and tilting of the baffle plate 68, and such adjustment is appropriately performed according to the density of leaf tobacco varieties, particularly the density of inner bones and lamina, and the amount of leaf tobacco supplied.

As shown in FIGS. 3 (a) and 3 (b), the squeezing teeth 38 of the present embodiment are formed by bending leg portions 80a, which are both ends of a bar 80 bent in a mountain shape, in the circumferential direction of the circumferential surface 32a of the rotating drum 32. It is formed by connecting many along. That is, the throttling teeth 38 project in the radial direction Y of the rotary drum 32 in a U-shape or a substantially V-shape in plan view. The respective teeth 38 are arranged along the circumferential direction of the circumferential surface 32 a of the rotary drum 32, and are arranged along the width direction X of the circumferential surface 32 a of the rotary drum 32.

When the rotary drum 32 having the teeth 38 of this shape is used, the teeth 38 in a U-shape or a substantially V-shape in plan view softly contact the leaf tobacco. For this reason, in the threshing portion 8, when the squeezing process is performed using relatively dried leaf tobacco having a moisture content of less than 15%, more specifically, about 6% to 10%, it is suppressed that the lamina is small and crushed It has been experimentally found that the separation performance between the inner bone and the lamina is enhanced.

On the other hand, when the leaf tobacco used as the raw material has a moisture content of high moisture state of, for example, 15% or more, the separation of the inner bone and the lamina by improving the catching of the leaf tobacco to the squeezing teeth 38 at the time of slushing treatment. Performance can be enhanced.
Specifically, as shown in FIGS. 4A and 4B, the removable secondary teeth 82 are attached to the teeth 38 of FIG.

The secondary teeth 82 in this case are in the shape of bars extending from the circumferential surface 32 a of the rotary drum 32 to the projecting end in the radial direction Y of the teeth 38. Pressing members 84 are attached to the legs 80a respectively at the squeegee teeth 38 provided at both ends in the width direction X of the circumferential surface 32a, and these two pressing members 84 and the respective secondary teeth 82 have a width direction A rod-shaped stay 86 extending in the X direction is penetrated.

Between the adjacent secondary teeth 82, two collars 88 which the stay 86 penetrates and abuts on the circumferential surface 32a are respectively disposed. As a result, the secondary teeth 82 are fixed to the respective teeth 38, and the movement of the stay 86 and the secondary teeth 82 during the threshing process is suppressed.

Further, as shown in FIGS. 5 (a) and 5 (b), a long plate-like attachment 90 may be attached along the width direction X so as to extend between the teeth 37. The attachment 90 is disposed slightly projecting in the radial direction Y from the projecting end of each squeegee tooth 38, and a large number of secondary teeth 92 are formed along the width direction X at the projecting portion of the attachment 90.

The attachment 90 is fixed to the teeth 38 by sandwiching the rod member 80 with a long plate-like pressing plate 94 extending in the width direction X and fastening the attachment 90 and the pressing plate 94 with a screw 96. Even in this case, as in the case of FIGS. 4 (a) and 4 (b), it is possible to improve the hooking of the leaf tobacco to the teeth 38.

On the other hand, the openings 44 formed in the basket 36 can also assume various shapes according to the type and supply amount of leaf tobacco. Specifically, as shown in FIG. 6, circular openings 44A may be arranged at the same pitch in both directions of the width direction X of the circumferential surface 32a of the rotary drum 32 and the basket 36 corresponding to the circumferential direction. . Further, as shown in FIG. 7, circular small-diameter holes 44 B of relatively small diameter may be closely arranged in a basket 36. Further, as shown in FIG. 8, circular openings 44 </ b> C having a relatively large diameter may be arranged in a staggered manner in the basket 36.

As described above, the deboning and separating apparatus 1 of the present embodiment includes the baffle plate 68 which forms the lower edge 24 a of the recovery port 24 in the wind separation unit 10, and the baffle plate 68 is stretched and tilted by the adjusting mechanism 70. It is acceptable. As a result, it is possible to easily perform setting of conditions corresponding to various physical properties and moisture content of leaf tobacco, and to provide a compact leaf tobacco deboning separation device 1 with high separation performance between inner bone and lamina.

Specifically, the air flow 78 formed in the opening area of the recovery port 24 and the flow path 64 is a simple operation of adjusting the expansion and contraction and tilting of the baffle plate 68 in accordance with the type and supply amount of the leaf tobacco used as the raw material. It is possible to appropriately change the area of. Therefore, the removal of the inner bone from the recovery port 24 can be effectively prevented, and the separation performance of the inner bone and the lamina in the wind separation unit 10 can be enhanced.

In addition, the bone removing apparatus 1 includes a first servomotor 34 for driving the rotating drum 32 in a variable rotation speed, and a second servomotor 52 for driving the blower 50 in a variable wind speed. The

second servomotors

34 and 52 are controlled individually. Thus, in addition to the adjustment of the baffle plate 68 described above, the wind speed of the air flow 78 blown from the blower 50 is independently adjusted according to the type and supply amount of leaf tobacco, and the area conversion point P of the air flow 78 is By moving, the removal of the bone from the recovery port 24 can be more effectively prevented. Therefore, the separation performance of the inner bone and the lamina in the wind separation unit 10 can be further enhanced.

Moreover, since the deboning separation apparatus 1 can adjust the rotation speed of the rotating drum 32 independently according to the kind and supply amount of leaf tobacco, the separation performance of the middle bone and the lamina in the threshing part 8 can also be achieved. It can be enhanced.

Also, the basket 36 and the rotary drum 32 can be detached from the housing 6 so that the basket 36 having various apertures 44 or the rotary drum having various teeth 38 depending on the type and supply amount of leaf tobacco. Can easily be replaced with 32. By replacing the rotating drum 32, the clearance adjustment between the teeth 38 and the basket 36 can also be performed. Therefore, the separation performance of the inner bone and the lamina can be enhanced in leaf tobacco of various physical properties and moisture content.

The teeth 38 are formed by connecting leg portions 80a, which are both ends of the rod-like member 80 bent in a mountain shape, along the circumferential direction of the circumferential surface 32a of the rotary drum 32. As a result, even if the leaf tobacco which is the raw material has a moisture content of, for example, less than 15%, more specifically, about 6% to 10%, and even if relatively dried, the middle bone and the lamina are separated well. can do.

Here, leaf tobacco is known to contain various components, such as enzymes that catalyze various reactions. Due to the qualities required of the final tobacco product, it may be better for the enzyme reaction not to proceed as much as possible. In this case, it is required to slow the progress of the enzyme reaction by performing the slushing treatment without setting the moisture of the leaf tobacco after harvest to a high moisture state. Therefore, by performing the slushing treatment with the squeezing teeth 38 having the above-described shape, even if the leaf tobacco is dried as the raw material, the middle bone and the lamina can be separated with high separation performance, and the tobacco meeting the required quality Products can be manufactured.

On the other hand, if the leaf tobacco used as the raw material is in a high moisture state where the water content becomes, for example, 15% or more, the

secondary teeth

82 and 92 as shown in FIG. 4 and FIG. At the time of the lancing process, the catching of the leaf tobacco on the squeezing teeth 38 is improved, and the separation performance between the inner bone and the lamina can be enhanced. Further, since the

secondary teeth

82 and 92 are detachably attached to the teeth 38, even if the rotary drum 32 is not replaced, depending on the type and supply amount of leaf tobacco, or according to the required quality of the tobacco product. By desorbing the

secondary teeth

82 and 92, the separation performance of the inner bone and the lamina can be enhanced in leaf tobacco of various physical properties and moisture content.

Further, as shown in FIG. 6 to FIG. 8, the holes 44 formed in the basket 36 are formed in small diameter holes, large diameter holes, same pitch array, or staggered array according to the kind and supply amount of leaf tobacco. Thereby, in leaf tobacco of various physical properties and moisture content, the separation performance of the inner bone and the lamina can be enhanced. In addition, since the basket 36 is removable, it is only necessary to prepare and replace various baskets 36 having various openings 44.

Although the embodiments of the present invention have been described above, the present invention is not limited to these, and various modifications can be made without departing from the spirit of the present invention.
For example, in the above embodiment, the

secondary teeth

82 and 92 are attached to the throttling teeth 38 when leaf tobacco in a high moisture state is a raw material. However, the present invention is not limited to this, and in the case where leaf tobacco in a low moisture state is a raw material, secondary teeth may be attached to the teeth. That is, the shape and arrangement of the teeth 38, the

secondary teeth

82 and 92, and the openings 44 are not limited to those described in the above embodiment, but the types of leaf tobacco, the moisture content, the supply amount, etc. Depending, it is possible to change appropriately.

Further, the configuration of the adjustment mechanism 70 is not limited to the above-described content as long as expansion and contraction and tilting of the baffle plate 68 are possible. Further, the adjustment mechanism 70 may be electrically connected to the control unit 42 so that control can be performed by changing the setting of the control unit 42.
In addition, although the first and

second servomotors

34 and 52 are individually controlled by the control unit 42, the first and

second servomotors

34 and 52 are directly adjusted individually without providing the control unit 42. It is good.
