Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dry leaf aligning apparatus used in a leaf picking apparatus for separating tobacco leaves of dried stem tobacco from a trunk.

[0002]

2. Description of the Related Art As one form of tobacco leaf harvesting work, tobacco cultivated in a field is harvested from the root of the trunk, and is directly suspended in a drying room and dried. Separation of tobacco leaves from is performed. In the leaf picking work for separating the tobacco leaves from the stem dried tobacco, it is troublesome to perform this by hand, and there is a limit in improving the work efficiency. Therefore, it has been proposed to machine the leaves from stem tobacco by a machine.

For example, Japanese Unexamined Patent Publication No. Hei 4-281778 (Japanese Patent Publication No. 7-102122) discloses a transport device for placing and transporting stem tobacco in a direction substantially perpendicular to the transport direction and sequentially transporting the trunk. Along with disposing a separating device in which a plurality of separating units for separating tobacco leaves from the trunk of the tobacco are arranged in a direction perpendicular to the transport direction, on the downstream side in the transport direction,
Below the separating device, there is described a leaf picking device arranged in a storage box for storing the dried leaves separated from the trunk by the separating device from the trunk according to the leafing position. In addition, Japanese Unexamined Patent Publication No.
Japanese Patent Publication No. 269269 also discloses a similar leaf-mowing device. The leaf splicing device can continuously separate tobacco leaves from the trunk of the stem dried tobacco, thereby improving work efficiency. Furthermore, since the stem dried tobacco is transported in a direction substantially orthogonal to the transport direction, the dried leaves that have been cut off from the leaves are easily separated and stored in the storage box according to the positions at which the trunk leaves.

[0004]

In the above-described leaf splicing apparatus, the stem tobacco is fed to the separating mechanism with the tobacco leaves hanging down, and the stem tobacco is placed at a higher position than at least the average length of the tobacco leaves. It is necessary to arrange the separating mechanism in the above. For this reason, it is inevitable that the dried leaves that have been removed have fallen in a state of swimming in the air by a predetermined distance before reaching the bottom of the storage box located below the separation mechanism.
In order to fall off the trunk in a nearly vertical posture and fall,
The posture of the conventional leaf-mogi device when the dried leaves fall tends to be asymmetric, and the posture of the dried leaves in the storage box becomes messy. In some cases, the drying process may be hindered, such as being uniform. For this reason, it is usually necessary to correct this asymmetric posture, which may lead to a decrease in work efficiency.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to occur in a leaf picking apparatus for separating tobacco leaves from stem tobacco conveyed in a posture substantially perpendicular to the conveying direction. In particular, the present invention has been made to solve the above-mentioned disadvantages, and more specifically, to enable the dried leaves after leaf picking to be stored in a uniform position in the leaf tobacco storage tank, thereby improving the productivity of leaf tobacco production. An object of the present invention is to provide a device for aligning dry leaves that can contribute more.

[0006]

According to the present invention, there is provided a leaf aligning apparatus for separating tobacco leaves from stem tobacco transported in a posture substantially perpendicular to the transport direction. In the storage tank that stores the dry leaves that have been removed from the leaf tobacco and separated from the tobacco separation mechanism, a variable inclination angle plate having a leaf side as a mountain side and a leaf tip side as a valley side is disposed. By adjusting the inclination angle of the leaves, the posture of the dried leaves when falling can be controlled.

According to this dry leaf aligner, the stem tobacco conveyed to the separation mechanism by the conveyance device is such that the tip of the tobacco leaf hanging down first has a leading end (upstream side) of the separation mechanism. Contact the inclined plate in the inclined posture,
As it is sent to the downstream side, the posture gradually falls down along the inclined plate, and in this state, it is separated from the trunk by the separation mechanism. For that reason, the dried leaves after separation do not fall in the air swimming state to the bottom of the storage box, and from the base of the leaf to the tip of the leaf,
The leaves are stored on the inclined plate with the leaves arranged on the mountain side and the leaves on the valley side. For this reason, it is possible to carry out the finishing drying processing of the dried leaves as it is, and the additional work such as the adjustment of the posture is greatly reduced.

[0008] The inclination angle of the inclined plate is adjustable, and depends on the length of the tobacco leaf of the stem tobacco to be leached, and also on the number of dried leaves stacked on the inclined plate. By adjusting the inclination angle, the posture at the time of falling of the dried leaves can always be controlled to be constant and the best posture. The adjustment of the inclination angle of the inclined plate may be manually performed by an operator while checking the state of the stacked dry leaves by eyes, or automatically performed using a conventionally known weight sensor or position sensor. Is also good. Preferably, said storage tub is divided into a plurality of compartments, preferably landings,
In addition, the inclined plates are provided for each section, and the inclination angles of the inclined plates can be changed simultaneously or individually. In this case, it is possible to store the dried leaves separately at each leafing position at the trunk, and when the inclination angle is individually variable, the leaf length of the tobacco leaf according to the leafing position is also taken into consideration. More precise attitude control is possible.

[0009] More preferably, a stopper for restricting the free fall of the dried leaves is arranged on the surface of the inclined plate. As a result, it is possible to prevent the dried leaves that have been cut off from falling along the inclined plate at the beginning of the leaf cutting operation, and good posture control can be performed from the start to the end of leaf cutting. Becomes In the present invention, any leaf-graining device for separating tobacco leaves from stem dried tobacco carried in a posture substantially orthogonal to the carrying direction may be used, and a conventionally known leaf-grooming device can be used as appropriate. Furthermore, the present inventors have filed Japanese Patent Application No. Hei 9-134663 as an improved leaf splicing device of this kind. The leaf splicing device is a transport device that transports stem tobacco placed in a state substantially perpendicular to the transport direction from an upstream side to a downstream side, and a plurality of devices that separate tobacco leaves from the stem tobacco transported by the transport device. Pieces of separation mechanisms are arranged in a direction orthogonal to the transport direction, and further, each of the separation mechanisms includes a pair of leaf spike rolls arranged in parallel to the transport direction, and a transport direction upstream side of the leaf spike rolls. And a pair of spiral blades arranged at the same position. It is particularly effective to attach the above-described dry leaf aligning device to the storage tank that stores the dry leaves that have been removed from the leaf in the leaf extracting device.

In addition, the upper surface side of the transfer device 20 is covered with a transparent reinforced plastic cover 63, and the work safety is secured together with the thin steel sheet shield curtain 62. A motor M is mounted on the frame base 10, and the motor M
(Not shown) is drivingly connected to a transmission mechanism (not shown) in the second transmission case 21. The rotation driving force of the motor M is transmitted to the drive shaft 27 by the transmission mechanism, and further transmitted to the rotation shafts 31 of the separation mechanisms 30 via the transmission mechanism (not shown) of the first transmission case 41. .

With the above configuration, the worker is allowed to use the trunk dry tobacco T
Is laid on the upstream end of the separating device 40 in the operating state, that is, when the tobacco leaf t hanging downward is placed in a state substantially perpendicular to the transport direction of the trunk dried tobacco T, as shown in FIG. At the same time, the spiral blades 32 of the mechanism 30 are pushed down and aligned by the spiral blades 32, and at the same time, fed by the spiral blades 32 toward the downstream side, that is, toward the leaf milling roll 33. At the same time, the stem tobacco T comes into contact with the transport chain 23 constituting the transport device 20 and is transported positively toward the lower surface of the separation device 40 by the claws 23a provided on the transport chain 23. The sent tobacco leaf t is torn off from the trunk m by being pulled downward between the grooves 34, 34 of the pair of leaf milling rolls 33, 33 as in the case of the conventional apparatus.

[0021] In the leaf splicing apparatus configured as described above,
Since the stem dried tobacco T is configured to be fed into the separation mechanism 30 in a state where the tobacco leaf t hangs down, the separation mechanism 30 is arranged at a position considerably higher than the bottom plate 1 of the frame base 10. For this reason, dried leaves t
Must fall in a state of swimming in the air by a predetermined distance before reaching the bottom plate 1 of the frame base 10 constituting the storage tank, and the posture of the dried leaves at the time of falling dried leaves is messy.

In the present invention, in order to avoid this, a plurality of (three in the figure) partition plates 5 are attached in the width direction of the frame base 10, and a space between the partition plates 5 and between the partition base 5 and the frame base 10 are provided. Between the side plates 2 and 3 in a posture in which the upstream side in the transport direction of the trunk tobacco T is the lower position and the downstream side is the upper position, that is, the tip side is the valley side and the leaf side is the mountain side. The inclined plate 51 is arranged in the posture, and the inclination angle of the inclined plate 51 can be adjusted. In the example shown in FIG.
Each inclined plate 51 is attached to the frame base 10 in a posture in which a front end side thereof is fixed to a support shaft 52 rotatably and horizontally mounted near a front end of the bottom plate 1 of the frame base 10, and a rear end thereof. The side has a length reaching a little to the rear of the pair of leaf spike rolls 33, 33.

One end of the support shaft 52 extends outside the side plate 3, and a handle 53 is fixed to the extension. A handle 54 with a screw is attached to the other end of the handle 53, and the operator holds the handle 54 and turns the handle 53 about the support shaft 52 as a pivot point so that the inclination angle of the inclined plate 51 can be set to an arbitrary value. Can be changed to In addition, the tip of the handle 54 can be abutted against the side plate 3 by rotating the threaded handle 54 to fix the position of the inclined plate 51. The tip of the handle 54 with a screw may be inserted and fixed in a hole formed in the side plate 3.

At the start of the operation, the inclined plate 51 is placed in an inclined posture in which the rear end side is close to the pair of leaf-rolling rolls 33, 33 as shown in FIG. In that state, stem dried tobacco T
Is disposed substantially perpendicular to the transport direction, the tip of the tobacco leaf t which hangs down first contacts the vicinity of the front end of the inclined plate 51, and gradually becomes closer to the inclined plate 51 as the transport device 20 sends it to the downstream side. At the end, the child is in a posture of lying down, and is finally torn off from the trunk m by the pair of leaf mower rolls 33, 33. The dry leaves t after the tearing are separated by the partitioning plate 5 according to the leafing position, and further gently on the inclined plate 51 from the leaf tip to the leaf, with the leaf tip being the valley side and the leaf tip being the mountain side. Arrange in the placed state.

Preferably, a stopper 55 made of an aluminum material or the like extending in the lateral direction is disposed on the inclined plate 51 to prevent the fallen dry leaves t from sliding down on the inclined plate 51. . The operator operates the handle 53 to gradually decrease the inclination angle of the inclined plate 51 according to the progress of the work, that is, according to the number of stacked dried leaves on the inclined plate 51. Thereby, the dried leaves are stored on the inclined plate 51 in an aligned posture. Therefore, it is possible to carry out the finishing drying treatment of the dried leaves as it is, and it is not necessary to perform an additional operation such as a correction of the posture.

Depending on the condition of the stem m and the tobacco leaf t in the stem tobacco T, the tobacco leaf t may not be removed during the passage of the tobacco leaf 33. The above-mentioned plate member 44 is provided in order to completely remove the tobacco leaf t in such a case, and the feeding of the tobacco leaf t is temporarily stopped by the plate member 44, and the leaf is transferred to the un-trimmed leaf. The stripping action of the stripping roll 33 is applied for a longer time than in a normal case. Thereby,
The phenomenon of leaving the tobacco leaf t is avoided.

4 and 5 show another embodiment of the apparatus for aligning dry leaves according to the present invention. Here, the configuration of the leaf towing device itself is shown in FIGS. 1 to 3 except that a plurality of sets of leaf tobacco separation mechanisms 30 are arranged in a horizontal line with their tips aligned without being alternately back and forth. Is substantially the same as Below the leaf tobacco separation mechanism 30, three partitioning plates 5a are arranged, and the storage tank for storing the dry leaves t after the leaf cutting has been divided into four. Also, in each storage tank, an inclined plate 51 having a stopper 55 is arranged in such a manner that the tip side is a valley side and the leaf side is a mountain side, which is the same as that shown in FIG. The adjustment mechanism of the inclination angle is different.

In this embodiment, a first horizontal shaft 70 is rotatably provided in front of the lower end of the frame base 10.
Arms 71, 71 are fixed to both ends toward the front (upstream side). Further, a second portion is provided between the tips of the arms 71, 71.
, And the tip side (leaf tip side) of each of the inclined plates 51 is pivotally attached to the horizontal axis 72. The rear end side (leaf side) of each inclined plate 51 has a common horizontal rod 5.
6 and a handle 57 is attached to the horizontal rod 56. Therefore, when the operator operates the handle 57, the four inclined plates 51 use the first horizontal axis 70 as a first pivot point (fixed fulcrum) and the second horizontal axis 72 as a second pivot point. As the two pivot points (moving fulcrums), the inclination angle and the position in the front-rear direction can be freely changed.

On the other hand, the vertical rear end edges 5b of the three partition plates 5a are provided with three upper, middle, and lower locking claws 5c, 5d, 5e.
Are attached, and the horizontal bars 56 provided on the rear end side of the inclined plate 51 are engaged with the engaging claws 5c, 5d, and 5e, so that the three inclined plates 51 can be inclined at respective inclination angles. ,
And a rear end of the vertical rear end edge 5 of the partition plate 5a.
The posture is maintained in a state substantially coincident with b. When the inclination angle adjusting mechanism for the inclined plate having this configuration is used, the rear end side (leaf base side) of the inclined plate 51 is always the same vertical line (that is, the rear end edge 5 of the partition plate 5a) as described above.
b) Because it moves along the direction, regardless of the amount of the dried leaves, the position of the leaf base of the dried leaves does not shift back and forth,
It can always be stacked on the inclined plate 51 at a fixed position. The locking claws may be further arranged in multiple stages, and may be vertically moved steplessly by appropriate means.

The above description is of a preferred embodiment of the apparatus for aligning dry leaves according to the present invention, and there are many other variations. For example, the inclination angle adjusting mechanism of the inclined plate 51 is not limited to the one shown in the figure, but may be any one. A conventionally known inclination angle changing mechanism driven by a motor may be adopted instead of the manual up / down adjustment by an operator. is there. Further, in the illustrated example, the inclination angles of the respective inclined plates 51 are changed at the same time.
May be adjusted. In this case, more precise posture control can be performed in consideration of the leaf length of the tobacco leaf depending on the leafing position. The illustrated leaf-graining device is merely an example, and the dry-leaf alignment device according to the present invention is a leaf-graining device for separating tobacco leaves from stem dried tobacco conveyed in a posture substantially perpendicular to the conveyance direction (for example, JP-A-4-281778 (JP-B-7-1021)
Of course, the present invention can also be appropriately applied to a storage tank in a leaf-graining device described in JP-A No. 22-269 or JP-A-6-269269.

[0031]

According to the leaf mowing apparatus having the apparatus for aligning dry leaves according to the present invention, the dry leaves that have been peeled off from the trunk by the separating mechanism are classified according to their leafing positions and stored in the receiving tank in an aligned state. Therefore, the efficiency of workability in post-finishing drying is greatly improved.
