Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for removing stem-dried tobacco from a stem-dried tobacco stem quickly and without damage and storing the leaves in each leaf segment and a leaf-sheathing apparatus thereof.

[0002]

2. Description of the Related Art As one form of work for harvesting tobacco cultivated in a tobacco field, for example, the stem is cut off from its root and harvested, and the whole trunk is hung in a drying facility to be dried in a predetermined dry state as a trunk dried tobacco. Is dried up. After that, the dried tobacco, that is, stem dried tobacco, is separated (leaf mochi) into trunk and leaves. This makes it possible to obtain dried tobacco leaves. This leaf picking work is generally performed manually, but various leaf picking devices and leaf picking devices have also been proposed.

A hand-operated leaf mogul, grasping the base of the leaf with fingers,
It was a method of picking leaves one by one so as to pull in the direction of the plant base, and accumulating each leaf division. Stem-dried tobacco leaf smoke produced in Japan is produced by this method.

On the other hand, in the prior art, the actual publication is Sho 62-168.
In the leaf picking work by the leaf picker disclosed in Japanese Patent Publication No. 71, the half-divided cylindrical holding members 1a, 1b shown in FIG. 9 are connected by a hinge 3, and the leaves bent at one end of the holding members 1a, 1b. Mochi blades 5a and 5b are provided, and the tops of the tobacco trunks are gripped by the gripping members 1a and 1b, and the blades 5a and 5b are manually moved to the root direction so that the roots of the leaves growing on the trunk are cut off. I was stripping off the leaves.

In the stem-moistening tobacco leaf moisturizing device disclosed in Japanese Patent Publication No. 24515/1990, as shown in FIG. 10, a pair of rotating rollers 11 pulls in the tobacco stem 13 from the root side, and at the same time, the outer circumference of the stem is increased. To cut the root of the leaf with the rotating blade part 15, and place a box 17 that can be accumulated for each leaf division section just below the blade part 15, and move this box 17 in the direction orthogonal to the trunk as appropriate. Then, the tobacco leaves 19 cut by the blade portion 15 were collected for each leaf division.

[0006] In the leaf picker for trunk dried tobacco disclosed in Japanese Patent Publication No. 5-78302, as shown in FIG.
A device 21 for grabbing the stem of the stem tobacco 13 to hang it and moving it laterally is provided, and a pair of rotating shafts 23 sandwiching the stem tobacco 13 are provided in a downward inclination in the moving direction of the stem tobacco 13,
By arranging the blade portion 25 having elasticity on the rotating shaft 23 and providing the fixed box 27 for accumulating the stripped leaves in the moving direction of the stem tobacco 13, the stem tobacco 13 is moved,
The tobacco leaves cut by the blade portion 25 of the rotary shaft 23 were collected in the fixed box 27 for each leaf segment.

[0007] In the leaf picking device disclosed in Japanese Patent Publication No. 7-102122, as shown in FIG. 12, a carrying device 3 for carrying the trunk 13 of the trunk dried tobacco in a horizontal posture in a direction orthogonal to the trunk.
1 is provided, and the grooved roll 33 that rotates on the rotation axis in the direction orthogonal to the tobacco trunk 13 is provided on the downstream side in the carrying direction of the tobacco trunk 13.
A plurality of them are arranged side by side in the longitudinal direction, and the leaves 19 are hung below the trunk 13 to move the trunk 13 in parallel, and the hanging leaves 19 are pulled downward by the rolls 33 facing each other to scrape the leaves 19 and remove the scraped leaves. It was accumulated for each leaf division in the partition frame 35 arranged immediately below.

[0008]

However, in manual leaf mogul, about 10 leaves are usually attached to one stem dried tobacco. For example, in the Burley variety, the number of stems per 10a is large. Since 2600 trees have been cultivated, the number of leaves that can be picked will be 26000, which means that each one will be picked off by hand. Furthermore, since one farmer cultivates 50a on average, the number of hand-picks is 130000. It is obvious that a large amount of labor is required to manually strip a large number of leaves one by one as described above, which is also a factor that hinders the expansion of production scale.

Further, in the leaf picking operation by the leaf picking device shown in FIG. 9, the leaf dividing operation is not carried out, so that it is necessary to separately perform the leaf dividing operation. Moreover, the leaves that have been stripped of leaves are disjointed, so the efficiency of sorting work is extremely poor, and labor saving cannot be achieved.

In the stem-moistening device of the trunk dried tobacco shown in FIG. 10, when the leaves 19 were not leaked, the mesophyll of the leaves 19 was greatly damaged by the rotary blade 15. Further, since a mechanism for forcibly dropping the strayed leaves 19 was not provided, the stripped leaves approached the stripping portion one after another, and the next leaf pushed the stripped leaves in the direction of the rotary blade 15 to the tip. There was a problem that the picked leaves 19 were wound around the rotary blade 15 before falling.

Further, in the leaf moist sorter for trunk dried tobacco shown in FIG. 11, the blade portion 25 having elasticity is brought into contact with the outer periphery of the trunk, but the trunk (root portion of the leaf) and the blade portion 25 are The contact between the leaves is instantaneous, and the cutting of the leaves 19 is not reliable. Further, the blade portion 25 unnecessarily comes into contact with the mesophyll portion of the leaf 19 which has not been leaked, and as a result, there is a problem that the leaf 19 is damaged.

Further, in the leaf mower device shown in FIG. 12, it is difficult to guide the leaf 19 between the leaf moat rolls 33, and the leaf 19 or the middle bones have a little water content or are inclined rearward in the conveying direction. When the leaf 19 is guided between the rolls 33 in this state, there is a problem that the leaf 19 is wound around the leaf shaving roll 33. Since the grooved roll 33 that enhances the gripping property of the leaves 19 is used, it is difficult to add a mechanism for preventing the leaves 19 from being wound.

On the other hand, in recent years, in addition to the medium-bone dryer, a compact dryer has been introduced to tobacco farmers so that finish drying can be performed immediately even if water remains on the leaves that have been stuffed. For this reason, there has been a strong demand for the development of a leaf picking device that can effectively use these drying facilities.

The present invention has been made in view of the above circumstances, and a method for leaf picking a trunk tobacco, which enables leaf picking to be carried out quickly and without damage without labor and storage for each leaf segment. An object of the present invention is to provide a leaf picking device, thereby saving labor, shortening working time, and improving tobacco leaf quality.

As shown in FIG. 5, the leaf mochi belt 83 made of 1b is
The sandwiching side belt facing portion is arranged narrowly so that only the base 93a of the tobacco leaf 93 can be securely sandwiched. The orbiting speed of the leaf moat belt 83 is set to be higher than the orbiting speeds of the transport belt 49 and the holding belt 65 described above.

Therefore, the conveyor belt 49 and the holding belt 6
In the trunk 67 transported by 5, the leaf base 93a of the tobacco leaf 93 that hangs vertically downward is sandwiched between the leaf mower belts 83, and by the circulation of the leaf mower belts 83 faster than the circulation speed of the transport belt 49. , Will be moved relative to the stockholder side of the trunk 67. As a result, the tobacco leaf 93 becomes 9
It will be stripped off even if it is pulled to the stockholder side with 3a sandwiched.

As shown in FIG. 6, the circulating belts 81a and 81b are provided at the end of the sandwiching path of the conveyor belt 49.
A scraper 95 is provided near the
The tobacco leaf 93 that rotates along with 1a and 81b can be separated.

The conveyor belt 49 is required to move the trunk 67 straight until the tobacco leaf 93 on the top of the trunk 67 comes off. Then, when the leaf picking of one trunk 67 is finished, it is possible to continuously feed the next trunk 67 to the leaf picking section 51, which is convenient and continuous.
It is preferable to have a linear distance equal to or more than the length and the total length should be twice or more.

A fixing releasing means 97 for releasing the fixing of the L-shaped pin 79 is provided in the vicinity of the conveying path of the conveying belt 49, at a position where the root of the trunk 67 reaches when the leaf picking is finished. The fixing releasing means 97 abuts only on the end surface of the trunk 67, which is fixed by the L-shaped pin 79, on the base side of the stock, thereby utilizing the movement of the conveyor belt 49 to move the L-shaped pin 79 from the stock side. It can be removed.

The frame 43 is provided with a rail-shaped shutter 99 extending in a direction orthogonal to the trunk 67.
The trunk 67 whose fixing is released from the L-shaped pin 79 by the fixing releasing means 97 is removed from the transport path. To remove the trunk 67 from the transport path, for example, the stock root contact surface of the fixing releasing means 97 described above is formed as an inclined surface, and the trunk 67 that has been transported is brought into contact with this tilted surface, and the trunk stock 67 of the trunk 67 is removed. This can be easily performed by moving the side while swinging along the inclined surface.

It should be noted that it is preferable to provide guides and belt tensions for correcting the looseness of the belt at appropriate intervals in the straight portion of the conveyor belt 49 so that the belt does not hang downward.

The conveyor belt 49 is provided with a protrusion 101 at a predetermined position for detecting the leaf segmentation position depending on the distance from the root side. The protrusion 101 collides with the limit switch 103 and is detected as a detection signal. This protrusion 1
01 is the conveyor belt 4 according to the length of various trunks 67.
It can be freely moved to any position of 9. Further, the protrusion 101
Is also provided at the final stop position together with the limit switch for stop in addition to the required leaf division.

A belt conveyor 105 that conveys the stripped tobacco leaves 93 to a selector provided in the other end direction of the frame 43 is provided below the leaf picking portion 51 in the trunk conveying direction. The belt conveyor 105 includes parallel horizontal rotating shafts 107a and 107 arranged on one end side and the other end side of the frame 43.
It is configured by hanging a flat belt 109 on b. The rotating shaft 107b arranged on the other end side of the frame 43 is arranged at a position higher than the rotating shaft 107a arranged on one end side of the frame 43. As a result, the belt conveyor 105 is
The transport surface is raised forward.

The inclination of the belt conveyor 105 corresponds to the fact that the stripped tobacco leaf 93 falls so as to fly forward with the leaf base 93a first.
It is designed to catch 3 without scattering. It is preferable that a guide plate (not shown) or the like is further provided upright on the belt conveyor 105 so that the tobacco leaf 93 does not jump out from the side of the belt conveyor 105. The belt conveyor 105 has, for example, a rotating shaft 107a and an electric motor 11
1 (not shown) to rotate and drive the flat belt 109 around. The belt conveyor 105 can also be started and stopped by an ON / OFF switch, like the leaf moat belt 83. Instead of the belt conveyor 105, a leaf moat belt 83 is extended to the sorter side (not shown), and the sorter 1
It is also possible to transport the leaves directly to 13.

FIG. 7 is an enlarged view of an essential part showing an example of the sorting machine. Belt conveyor 105 or leaf mochi belt 81a,
A sorting machine 113 for collecting the transferred tobacco leaves 93 is arranged at the end of the tobacco transfer direction of 81b. The sorter 113 has a structure including a plurality of storage areas appropriately divided, and operates according to the detection signal of the above-mentioned protrusion 101,
The tobacco leaves 93, which are divided into leaves according to the position, can be stored. In the sorting machine 113, the electric motor 115 and the fixed pipe 117 are appropriately connected to the frame 43.
The fixed pipe 117 has a shaft 119 penetrating therethrough.
Is rotatably inserted.

At the lower end of the shaft 119, the V pulley 12
1 is fixed. The V pulley 121 and the electric motor 11
The V belt 12 is fixed to the V pulley 123 fixed to the drive shaft of
The shaft 119 is rotated by the electric motor 115 via the V-belt 125. Fixed pipe 117
A cylindrical circular cam plate 129 is fixed to the upper end of the.
A base end of a partition plate 131 that is long in the radial direction is fixed to the shaft 119 protruding from the upper end of the fixed pipe 117.

A bottom plate 133 is attached to the partition plate 131 so as to be pivotable downward by a hinge 134, thereby forming a storage area for sorting tobacco leaves. A base end of a bottom plate opening / closing arm 135 bent in a crank shape is fixed to the bottom plate 133. By cutting the upper edge of the circular cam plate 129, a cam groove 129a is formed at a position and a depth required for opening and closing the bottom plate 133. At the tip of the opening / closing arm 135, the cam groove 12 of the circular cam plate 129 is formed.
A cam follower 137 that rotates in contact with 9a is attached.

Therefore, the bottom plate 133 is opened downward when the partition plate 131 is rotated and the cam follower 137 reaches the cam groove 129a. Further, when the shaft 119 further rotates and the cam follower 137 rises along the circular cam plate 129, the bottom plate 133 closes. Another circular cam plate 129 arranged concentrically on the fixed pipe 117 is for opening and closing the bottom plate 133 attached to another partition plate (not shown). Sorting machine 1
The storage box 139 is arranged below the bottom plate 133 which opens and closes at a predetermined position in this way, and the tobacco leaves 93 sequentially transferred by the belt conveyor 105 or the leaf mochi belts 81a and 81b are transferred at predetermined transfer intervals. It can be sorted and collected. It is needless to say that the length of the leaf picking device 41 can be further shortened and the device can be made compact by arranging the sorter 113 closer to the leaf picking belt 83 side.

In addition, the leaf picking device 41 has a driving device (not shown) for driving each part, and a control device (not shown). Further, the leaf picking device 41 is provided with a cover (not shown) or the like on the rotating portion and a safety device such as an emergency stop button.

Next, the procedure of the method for picking leaves from the trunk dried tobacco using the above-mentioned leaf picking device 41 will be described. FIG. 8 is an explanatory diagram showing the process of the leaf picking method. The leaf mogulator 41 is
When the storage box 139 is set in the sorter 113, the power source is connected, and it is in a movable state, it can be used immediately. The trunk dried tobacco is supplied to the leaf picking device 41 with the trunk 67 substantially horizontal with the tobacco leaves 93 hanging downward, with the root side of the trunk 67 being the tip.

Supply to the leaf picking device 41 of the trunk 67 is performed by pressing the start button and inserting and fixing the stock side of the trunk 67 into the L-shaped pin 79 provided on the revolving conveyor belt 49. By the transportation of the trunk 67, the tobacco leaves 93 are sequentially inserted into the nipping path of the leaf moat belt 83 from the root side. At this time, the entrance to the leaf moat belt 83 has a large circular orbit and becomes gradually narrower, so that the tobacco leaf 93 can be smoothly inserted.

Leaf base 93a sandwiched between leaf mochi belts 83
Indicates that the orbital speed V2 of the leaf mogul belt 83 is
Since it is faster than the orbiting speed V1 of 9 (V1 <V2), it is separated by pulling it toward the stocker side, and then it is blown from the end of the pinching path of the leaf moat belt 83 toward the belt conveyor 105 or the sorter 113. And then released. Since the leaf mochi belt 83 conveys the tobacco leaf 93 at a high speed in the traveling direction, the leaf clogging does not occur. Also, Hamoto 9
Since the force of the leaf moth is applied only to 3a, the tobacco leaf 93
There is little damage to.

It should be noted that the conveyor belt 49 stops when the trunk 67 reaches the first leaf division section after the trunk dried tobacco is supplied.
The conveyor belt 49 waits for the sorter 113 to move the partition plate 131 to the next leaf segmenting position, receives a signal from the sorter 113, and starts transporting to the next leaf segmenting range. Then, by reaching the end position of the next leaf segmentation,
Stop again. As described above, similarly, the transport belt 49 repeatedly moves and stops the number of times according to the number of the leaf divisions to operate.

The stem dried tobacco after all the leaf shavings has reached the final stop position (start position on the opposite side) and stopped,
It goes into a standby state. In this state, pressing the start button again starts the transportation of the next trunk dried tobacco.

At this time, when the trunk 67 fixed to the L-shaped pin 79 of the conveyor belt 49 reaches the leaf mog end point, the stock release side comes into contact with the fixing releasing means 97 and is pulled out from the L-shaped pin 79. The fixation is released. The released trunk 67 is detached from the conveyor belt 49 and guided and accumulated at a certain place by the shutter 99.

On the other hand, the tobacco leaf 93 transferred by the leaf-sheath belt or belt conveyor 105 is conveyed to the sorting machine 113 provided at the end of the transfer passage of the leaf-sheath belt or belt conveyor 105. In the sorting machine 113, tobacco leaves 9
3 is rotatably conveyed to the top of the storage box 139, which is the same leaf division, and the bottom plate 133 is opened to accumulate the tobacco leaves 93 in the storage box 139 for each leaf division.

At this time, the operation of the sorting machine 113 is performed in conjunction with the conveyor belt 49. That is, when the conveyor belt 49 reaches the upper limit position of the same leaf segmentation range and the protrusion 101 installed on the conveyor belt 49 collides with the limit switch 103, the electric motor 115 of the sorter 113 receives an electric signal to drive, The next partition plate 131 is rotated and moved to the leaf moat belt or belt conveyor 105 side. Shaft 11
9 detects the protrusion 121a (see FIG. 7) provided on the V pulley 121 by the limit switch 136,
The electric current of the electric motor 115 is cut off, and the rotary movement of the sorter 113 is stopped. At the same time, this limit switch 136
The signal of the contact of the protrusion 121a with the conveyor belt 4 is
9 is used as a signal for operating the next leaf segmentation.

By repeating the above operation,
It is possible to accurately transport trunk dried tobacco and to divide the leaves. The conveyor belt 49 and the sorter 11
For the synchronous operation with 3, the protrusions 101 and 121a and the limit switches 103 and 136 may be used, and as another means, for example, a programmable sequencer capable of storing a series of control operations may be used.

Tobacco leaves 93 thus stored
Will face the same direction, and leaf alignment will be easy.
By using a box for drying inner bones (finishing drying) or the like to be carried out thereafter, the whole box can be taken out from the storage box 139. Therefore, in the leaf picking operation by the leaf picking device 41, supply of the trunk 67, removal of accumulated residual trunks, and storage box 139.
Only the tobacco leaf 93 is taken out from.

In the trunk drying, it is particularly convenient to use the leaf moisturizing device 41 from the end of the browning period when the tobacco leaves 93 turn brown to the time of entering the mid-bone drying period for drying the middle bones. That is, at this time, water remains in the middle bones and the middle bones are in a soft and withered state. In this state, there is little loss of tobacco leaves 93 and breakage of the middle bones, and when the trunk 67 is horizontal, the tobacco leaves 93 hang downward, so that the leaf picking device 41 according to the present invention can be easily implemented. Further, since a mid-bone drying (finishing drying) facility is also prepared today, it is also possible to conveniently carry out the leaf picking before finishing drying.

In the method of stripping the dried tobacco leaf 93 from the trunk, there is the reality that the stripping force of the tobacco leaf 93 is small and stable when the tobacco leaf 93 is pulled to the base side. this is,
This is because axillary bud cells are prepared between the stem 67, which is the epiphytic part of the tobacco leaf 93, and the middle bone, and are easily peeled off when a downward force is applied to the middle bone. In the present invention, since it is premised that water remains in the middle bones and tobacco leaves 93, damage to the tobacco leaves 93 due to the leaf picking operation can be reduced, and the leaf holding force acts on the plant side, It is possible to reliably carry out leaf mogul with a small force. As a result, according to the leaf picking method using the leaf picking device 41 described above, it is possible to save labor of the leaf picking work, shorten the working time, and further improve the quality of the tobacco leaf 93.

As described in detail above, according to the method for stalking stem dried tobacco according to the present invention, the stem base side of the stem dried tobacco on which the tobacco leaf hangs is the tip in the central axis direction of the stem. Conveyed, the leaf base of the drooping leaves is sequentially sandwiched from the plant side between the leaf mochi belts, and the leaf base is stripped to the plant side by orbiting the leaf moat belt faster than the conveying speed of the conveyor belt.
Tobacco leaves can be quickly and without damage damaged with a small force, and the speed of the moistening operation can be extremely increased.
Then, the tobacco leaves picked up by nipping the leaf base are discharged from the end of the nipping path of the leaf mochi belt, and if the leaf base is sequentially dropped downward in the conveying direction, the directions of the tobacco leaves are neatly aligned in the same direction. be able to. Further, the tobacco leaves dropped from the leaf shaving belt can be transferred to an appropriate place in the order of sitting by receiving and placing the tobacco leaves on a belt conveyor as necessary. Further, tobacco leaves sequentially transferred by the leaf mogul belt or belt conveyor are sorted in a predetermined transfer interval at the end of the transfer path of the leaf mogul belt or belt conveyor and accumulated, and the tobacco leaves are sorted in the same direction for each leaf classification. Can be stored at. According to the above-mentioned leaf picking device, the conveyor belt which conveys the trunk dried tobacco in the direction of the central axis of the stem with the root side as the tip, and the leaf edge of the hanging tobacco leaf is sandwiched to be faster than the conveying speed of the conveyor belt. Since the leaf mochi belt to be circulated is provided, the leaf base of the tobacco leaf can be easily separated to the plant base side. And, since the conveyor belt is provided with the trunk fixing means for holding the stocker side of the trunk and restricting the relative movement in the carrying direction side with respect to the carrying belt, easy carrying and releasing of the trunk dried tobacco, and further the stocker Forces can be applied to the side to enable the leaf moat to separate the tobacco leaves. Further, by providing a belt conveyor below the leaf mogul belt, the tobacco leaf dropped from the leaf mogul belt can be received and transferred. Furthermore, if a sorting machine is provided at the end of the transfer path of the leaf mogul belt or belt conveyor, the tobacco leaves sequentially transferred by the leaf mogul belt or belt conveyor can be sorted and accumulated at predetermined transfer intervals. Further, when the sorting machine is provided with a plurality of rotatable storage areas and is configured to interlock with the transfer timing of the conveyor belt, the sorting of tobacco leaves can be further facilitated and ensured.
