DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Industrial applications]

[0002] The present invention relates to a leaf picking apparatus for separating dried tobacco leaves from stems.

[0003]

[Prior art]

[0004] As one form of tobacco leaf harvesting work, tobacco grown in a field is harvested from the root of the trunk, suspended in a drying room and dried, and the trunk is dried. Separation of tobacco leaves has been performed.

[0005] Leaf picking, which separates tobacco leaves from the stem of stem dry tobacco, is time-consuming if performed manually, and there is a limit to the improvement of work efficiency.

[0006] Therefore, there has been proposed a leaf splicing apparatus for performing a leaf splicing operation by a machine.

For example, Japanese Patent Laid-Open Publication No. 4-281778 discloses a transport device for placing and sequentially transporting trunk tobacco in a direction substantially perpendicular to the transport direction, and separating the tobacco leaves from the trunk of the trunk tobacco. A separation device in which a plurality of separation units are arranged in a direction perpendicular to the conveyance direction is disposed downstream of the conveyance direction, and the tobacco leaves that have formed on the trunk of the stem dried tobacco are aligned toward the separation unit. A leaf picking device in which the device is arranged upstream of the separating device in the transport direction is described.

[0008] The leaf splicing apparatus can separate the tobacco leaves from the stem of the stem dried tobacco by separating them according to the position where they are set on the trunk. In addition, the separation operation is performed continuously and the efficiency of the separation operation is improved. Further, by arranging the aligning device on the upstream side in the transport direction of the stem tobacco with respect to the separation device, the tobacco leaves of the stem tobacco transported to the separation device are aligned toward the separation unit. As a result, it is possible to prevent the generation of tobacco leaves remaining without being separated from the trunk, and to surely separate the tobacco at each epiphytic position.

[0009]

[Problems to be solved by the invention]

[0010] However, the leaf splicing device described above is not sufficient to prevent the generation of tobacco leaves remaining without being separated from the trunk, and is horizontally placed in the tobacco leaves aligned by the aligning device and hangs down. Because there are things that do not fall, and because the tobacco leaf itself is extremely lightweight and easily affected by vibration, etc., the tobacco leaf is not separated from the trunk,
In some cases, mistakes occurred in leaf picking.

[0011] In addition, when leaf cutting is performed in a state in which the leaf is not completely hung down, only a part of the tobacco leaf is peeled off, and the tobacco leaf may be damaged.

[0012] Therefore, there has been a demand for a means for separating tobacco leaves according to their epiphytic position on the trunk and for reliably separating the tobacco leaves, and for preventing the occurrence of mistakes in leaf picking and damage to the tobacco leaves.

[0013]

[Means for Solving the Problems]

[0014] Means for solving the problems of the present invention are as follows.

First, a transport section for transporting the stem tobacco placed in a state orthogonal to the transport direction from the upstream side to the downstream side, and a direction of the tobacco leaves of the stem tobacco transported by the transport section. Alignment part to be aligned, comprising a separation part to separate the tobacco leaves from the stem tobacco aligned the direction of the tobacco leaf by the alignment part, as an alignment part, from the upstream side to the downstream side,
A combination of the first rotating brush and the second rotating brush so that the brush tips contact each other is arranged, and then a plate brush having a vertically hanging brush is arranged so as to be orthogonal to the transport direction, Finally, a plurality of sets of brush rolls each having two spindles, each having a spindle shape, and having a rotation axis parallel to the transport direction are arranged, and a separation unit having two sets each having the same rotation axis as the brush rolls. A leaf-moggi device with multiple sets of mogi rolls.

Secondly, a plurality of sets of two leaf moire rolls having the same rotation axis as the brush roll are arranged as a separating section, and a leaf mossy roll is provided at the landing position of the top leaf of the stem dried tobacco. The leaf removing device according to the first aspect, wherein a disk cutter is provided instead of the leaf cutter.

Thirdly, there is provided a partition plate which is arranged along the transporting direction and separates the tobacco leaves separated from the trunk dried tobacco by the separating section according to each landing portion, and at the downstream side of the plate brush, 3. The leaf removing device according to the first or second aspect, further comprising a guide for guiding tobacco leaves between the brush rolls.

It should be noted that the term "perpendicular" includes not only a case where the angle is exactly 90 degrees but also a case where the angle is slightly shifted as long as the effects of the present invention can be obtained.

[0019]

[Action]

The stem dried tobacco conveyed from the upstream side to the downstream side by the conveying section passes through the space between the first rotating brush and the second rotating brush of the alignment section, and is attached to the trunk by the rotating brush. Tobacco leaves are aligned in one direction.

Thereafter, the tobacco leaves attached to the trunk are aligned downward by the brush that hangs vertically by passing through the plate brush, and hang down.

Then, the tobacco leaves arranged downward are
It is nipped by a pair of brush rolls from both sides, and is transported from the alignment section to the separation section while maintaining a state of completely hanging down.

Here, in the case where a guide for guiding the tobacco leaf to the brush roll is attached, the tobacco leaf aligned by the plate brush is reliably transported between the brush rolls by the guide.

In the separating section, the tobacco leaf which hangs completely downward enters between the leaf-mogi rolls, is pulled downward by the rotation of the leaf-mogi rolls, is torn off from the trunk, and falls down.

In the landing portion of the top leaf, the trunk of the top leaf landing portion is thin, and there is a possibility that the trunk may be caught in the leaf spike roll. To prevent this entrainment, a disc cutter is used instead of the leaf spike roll. Is attached, and the tobacco leaf of the top leaf is cut from the base of the leaf and falls downward by the disc cutter.

The partition plate separates the tobacco leaves falling from the trunk without mixing with the tobacco leaves in the next landing position.
