FIG. 5 shows a continuous folding device 70 suitable for placing the leaf tobacco on the workbench 16 in a state where the tobacco is woven into the connecting rope.
It is shown.

First, as shown in FIG. 4, an operator first obtains a plurality of connecting ropes R (for example, 5 to 6 connecting parts) from an assembly Ls of leaf tobacco L woven into a connecting line using a connecting folder 70. ) Is taken in a folded state. Here, the continuous folding device 70 includes a rod-shaped main body frame 72 and a U-shaped hook 7 attached to one end thereof as shown in FIG.
And 4. The length dimension Lr of the main body frame 72 is set to approximately half the length of the connecting rope R,
The maximum width W and the maximum depth D of the hook 74 are 5-6.
The size is set to be large enough to hook the consecutive rope R. Therefore, the worker can pick up a plurality of connecting lines R from the integrated body Ls at once by hooking the hook 74 on the central portion of each connecting line R. Further, as shown in the figure, if both ends (the portion where the leaf tobacco is not woven) of the connecting rope R are gripped with the main body frame 72 with one hand, a plurality of connecting ropes R can be easily formed as shown by a two-dot chain line in the figure. Can be transported.

Next, the leaf tobacco L is placed on the workbench 16 as shown in the state where the plurality of connecting ropes R are folded in two.
The tobacco row Lq is formed on the worktable 16. At this time,
The longitudinal direction of the connecting line R is aligned with the left-right direction of the work table, and the connecting line R is arranged on the near side of the work table 16 with respect to the row of leaf tobacco Lq. At this time, if the work table 16 is pulled out as shown in the figure, the leaf tobacco L can be easily placed. Thereafter, when the work table 16 is pushed into the proper position and the above-described lever switch 62 is tilted downward (down switch is turned on), the holding plate 28 is automatically lowered (see FIG. 6). Therefore, the tobacco row Lq on the worktable 16 is
The work table 1 is pressed from above by the press plate 28.

It is needless to say that the part is out of the range.

Next, the worker operates the leaf tobacco row L in the state shown in FIG.
Pull out all the connecting lines R from q along the work table. Thereby, the leaf removing operation of the leaf tobacco L is completed. When the above-described leaf removing operation is completed, the lever switch 62 is tilted upward (the up switch is turned on) to raise the holding plate 28 (see FIG. 7). At this time, the connecting line R extracted from the leaf tobacco L is arranged until the holding plate 28 reaches the ascending limit position and stops automatically.

FIG. 8 shows a flow of an operation of picking (sorting) the extracted leaf tobacco L and packing the leaf tobacco L after the picking. First, the operator pulls out the worktable 16 from the apparatus main body, and in this state,
Picking of the tobacco L is performed. At this time, since the fluorescent lamp 68 is turned on, the picking operation can be performed more reliably using the illumination.

When the picking operation of the leaf tobacco L is completed, the operator divides the leaf tobacco L placed on the worktable 16 into two large parts, and divides the leaf tobacco L into one unit, that is, twice. It is transported and put into the press 76. At this time, it is not particularly necessary to bind the united leaf tobacco L with a paper string or the like. The work of removing and sorting the leaf tobacco woven into the continuous rope is performed by repeating the above-described operation procedure. Here, the inventors of the present invention conducted an experiment for executing the above-described series of work procedures, measured the time required for the series of work, and obtained the required time. Further, the usefulness of the present invention was verified by comparison with the time required for a commonly used leaf removing operation without applying the leaf removing device of the present invention.

Referring to Table 1, for example, when leaf tobacco removal, selection, squeezing, and packing operations for 40 consecutive tobaccos were performed, the average time (unit: seconds) required for the series of operations was calculated for each process. It is shown. In addition, as shown in the right column of Table 1, the experiments were conducted using the leaf removing device of the present invention and the case of the conventional manual operation. I went about.

It should be noted here that when the present invention is used, a leaf removing operation and a picking operation (operation steps 4 to 6)
Is significantly shorter (400 seconds for double leaves and 225 seconds for true leaves) compared to conventional practices (935 seconds for true leaves and 585 seconds for true leaves). In addition, since packing of the leaf tobacco does not require a binding operation before being put into the pressing machine, the operation time is shortened accordingly, and foreign matter such as a paper string does not enter the packed leaf tobacco.

According to the leaf removing device of the embodiment described above, when picking a leaf tobacco, the work table 16 can be pulled out from the main body of the device and used. There is no obstacle to the work, and the workability can be greatly improved. In addition, by using the above-described continuous folding device 70, it becomes easy to place the leaf tobacco on the work table 16, and the work efficiency can be further improved.

Further, the above-described series of leaf removing operation, picking operation and squeezing / packing operation can be performed easily by one worker consistently. In addition, the operator need only repeat the standing work at the work place, and the labor is greatly reduced. Therefore, a series of operations can be performed easily and efficiently, and the work space can be reduced in size.
