After harvest, it is dried in a drying facility. Conventionally, when drying, a rope (line rope) made of linen made of hemp
The tobacco leaf is sandwiched between the twists, and the entire chain is suspended in the drying facility. The insertion of the tobacco leaf between the twisted ropes is performed manually by an operator, and the twist of the continuous rope is expanded at a fingertip of one hand at a glance, and the spread hand twists the tobacco leaf with the other hand. Insert the leaf. In this case, the base of the tobacco leaf protrudes from the connecting line by 3 cm to 5 cm and is held by the connecting line. However, there is a limit to the size of the expanded twist, and since the curvature of the midbone of the tobacco leaf is large, it is not easy for the worker to insert the twist into the twist,
This method requires a highly skilled worker. Further, the number of leaves to be knitted is as large as 60,000 on average per 10a. Considering the knitting technique and the number of knitted yarns on a continuous rope, the labor burden on the worker is extremely large, and furthermore, a large amount of working time is required.

ある。[0003] Tobacco leaves sandwiched in this way are:
The entire rope is suspended from both ends of a pipe serving as a hanging hand on both sides of the drying chamber, and is dried. The state of the tobacco leaf is a vertical state in which the tip of the leaf is downward with respect to the continuous rope stretched almost horizontally. Usually, the thickness of the connecting rope used for leaf knitting is about 9 mm, the length is 4.5 m in total length, and the actual knitting position is
It is a part of about 3.6m at the center excluding about 45cm at both ends of the connecting rope.

For example, Japanese Utility Model Application Laid-Open No. 52-137000 discloses that a continuous rope is expanded to have a rhombic shape. Work machine is disclosed. This device mechanically expands the twist of the lanyard and saves labor in that aspect, but the work of inserting tobacco leaves into the lanyard is still performed manually. However, it is not sufficient from the viewpoints of both reducing the work load and the work time. If it takes time to weave the tobacco leaves, the work before and after the leaf knitting is greatly delayed, which may cause a decrease in the quality of the harvested leaves and the like.

的に有利でない。On the other hand, tobacco leaves are arranged in a thick layer on a conveyor belt, and a pipe serving as a hanging tool is sandwiched between the layers, and while the tobacco leaves are continuously moved, the leaves are knitted with a downstream sewing machine. The device which was made to perform
It has been proposed in 1896 and the like. The leaf-knitted tobacco leaves are hung on a pipe, suspended in a drying room in that position, and dried. However, this apparatus performs knitting of yellow seeds, and places tobacco leaves on a conveyor belt in a thick layer of about 5 cm, and then places 1.8 tons thereon.
m, a tobacco leaf is placed thereon in a thick layer of about 5 cm, and a middle bone portion of the tobacco leaf is knitted by a sewing machine while the pipe is sandwiched. The pipe is hung in a drying chamber while being sandwiched between tobacco leaves. This method can increase the supply speed of tobacco leaves, but in the case of native and burley varieties, if the leaves are knitted and dried as a thick layer due to their drying characteristics, etc. Therefore, it is impossible to apply this method to native species and burley species as they are. Also, it is possible to knit leaves with a thin layer on the pipe,
In that case, the introduction cost of the pipe becomes expensive, which is not economically advantageous.

In addition, the current connecting line or the like can be used as it is as the string member N for weaving the tobacco leaf, the hanging tool and the existing drying facility can be used as they are, which is economically advantageous, and the leaf feeding position is also horizontal. There is also an advantage that both the manual leaf feeding and the mechanical leaf feeding can be easily performed because the feeding is on the transport conveyor in the state. Further, when the tobacco leaves are removed from the string member N after the drying is completed, the string member N and the tobacco leaf can be easily separated by manually pulling the thread on the suturing end side. As compared with the case where tobacco leaves are sandwiched between the leaves, there is no dropout due to the breakage of the middle of the leaves at the time of leaf removal, and unnecessary decrease in yield is also avoided.

た。SUMMARY OF THE INVENTION In the process of continuously knitting leaf leaves of tobacco leaves of a conventional type and a burley type using the above-mentioned tobacco leaf knitting apparatus, the present applicant has developed a leaf knitting process. In the apparatus, the entire length of the string member N passes through the sewing machine mechanism M, including both ends (usually, each having a length of about 45 cm) of the string member N that does not originally need to weave tobacco leaves. The time required for both ends of the string member N to pass through the sewing machine mechanism M can be considered as a loss of knitting time, and the mechanism for reciprocating the sewing machine mechanism back and forth in tandem with the suturing action is complicated and care must be taken for its maintenance. And the fact that the structure of the string pulling out means is somewhat complicated and requires elaborate assembly, etc., and after knitting the tobacco leaves on the string member over a certain length, Due to the resistance caused by the tobacco leaves being in contact with the conveyor belt surface, the cord member was sent at the same speed as the conveyor belt without being mechanically pulled out by the cord pulling means on the downstream side of the conveyance. .

FIG. 13 is a modification aiming at further stabilizing the feeding of the connecting line N after the leaf knitting. In this example, the first line N downstream of the sewing machine mechanism M is used.
And a pair of gears 5 on the back side of the second endless belts 11 and 12.
1a and 51b are arranged, and a pair of guide plates 52a and 52 for guiding the connecting line N transferred along the space S between the first and second endless belts 11 and 12 downward.
b is provided. The pair of gears 51a and 51b is driven via a power transmission system (not shown) so as to intermittently rotate in the direction shown by the arrow at the same peripheral speed as the peripheral speed of the conveyor belt 10. The leaf-knitted rope is connected to the pair of guide plates 52a, 5a.
2b, it is drawn below the conveyor belt 10, and is sent out at a constant pitch to the downstream side by the engagement of the pair of gears 51a, 51b. Thereby, even after the end of the connecting line N is separated from the first string support member 30a, the feeding to the downstream side is ensured. By making the distance between the pair of gears 51a and 51b changeable, it is possible to smoothly operate the connecting lines having different thicknesses.

き、装置の維持管理も容易となる。According to the apparatus for knitting tobacco leaves according to the present invention, the operator simply places the harvested tobacco leaves on the conveyor belt in a predetermined posture and sew the tobacco leaves together to form a continuous rope. Therefore, as compared with the conventional method, the twisting of the connecting rope is expanded with a finger, and the operation is simplified as compared with the method of inserting the midbone into the twisted hand with one hand, thereby making it possible to greatly reduce labor. In addition, since only the portion of the string member where the tobacco leaves need to be woven is sent to the sewing machine mechanism, the woven time can be reduced. Furthermore, the transport belt is intermittently moved in conjunction with the sewing operation of the sewing machine mechanism, and does not have a complicated mechanism for reciprocating the sewing machine mechanism. And the maintenance and management of the device becomes easy.
