Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a leaf knitting machine for leaf tobacco, in which a large number of leaf tobaccos are continuously placed on a conveyer conveyor and the leaf tobaccos moving with the operation of the conveyer conveyor are knitted by a knitting needle. .

[0002]

2. Description of the Related Art Harvested leaf tobacco is dried while being suspended in a drying chamber. At that time, a large number of leaf tobaccos with aligned petioles are arranged in a horizontal row, and a leaf knitting machine is used to knit along the petiole portions so that the tobaccos arranged in a horizontal row are not separated. Then, the petiole part of the leaf tobacco is locked to a rod-shaped hanger and suspended in a drying chamber. Conventionally, the leaf knitting machine used in the above-mentioned leaf knitting process has a leaf knitting needle arranged on one side of the starting end side of the conveyer conveyor, and a large number of the leaf knitting needles arranged on the conveyer conveyor while reciprocating the leaf knitting needle up and down by a drive mechanism. It is configured to knit leaf tobacco.

Specifically, a large number of leaf tobaccos are arranged on a conveyer conveyor with the petioles aligned, and at the same time the leaf tobaccos are moved at a constant speed by the operation of the conveyor.
The yarn was knitted along the petiole part of the leaf tobacco which was aligned by continuously moving the leaf knitting needle up and down. It should be noted that the above-mentioned leaf knitting is an operation of gathering petioles of leaf tobacco with a needle and a thread, so it is exactly "leaf stitching", but it is called "leaf knitting" in this field.

[0004]

SUMMARY OF THE INVENTION As described above, the most troublesome work in performing leaf knitting work on leaf tobacco is as follows.
It was a work of carefully arranging a lot of leaf cigarettes on a conveyor with the petioles aligned, and a lot of labor and time was spent on this work. The leaf knitting work of leaf tobacco is performed in order to collect the leaf tobacco which is dried in a suspended state in a drying chamber so as not to fall off, and as described above, it is not always necessary to put together the petioles. Therefore, at the time of harvesting leaf tobacco, if it is possible to knit the leaf tobacco that has been separately harvested by a mechanical harvesting machine, etc., by arranging the leaf tobacco as it is by the leaf knitting machine, it is possible to greatly save the labor of the above work. .
This allows leaf tobacco to be dried in a conventional drying chamber as well.

However, when the above-mentioned conventional leaf knitting machine is used to knit the leaf tobacco, which is placed on the conveyor in a discrete manner, with one stitch, the stitch portion can be gathered, but another portion apart from the stitch can be separated. The parts would be scattered, and it was impossible to put together the dissociated leaf tobacco so that it could be suspended. The object of the present invention is to improve the above-described leaf knitting machine, by weaving the leaf tobacco placed on the conveyer in a disjointed state, and providing a function that can be put together in a suspended state. Is to reduce the labor of.

[0006]

In order to achieve the above-mentioned object, the present invention is to place a large number of leaf tobacco on a conveyor and to move leaf tobacco which is moved by the operation of the conveyor by leaf knitting needles. The leaf knitting machine for knitting is characterized in that a plurality of the leaf knitting needles are arranged at a predetermined interval in a direction orthogonal to the carrying direction of the carrying conveyor. It is preferable that the leaf knitting machine be configured such that the transport speed of the transport conveyor and the weaving speed by the leaf knitting needle can be adjusted.
Further, the transport speed of the transport conveyor and the weaving speed of the leaf knitting needles may be proportionally increased or decreased.

It is effective that the above-mentioned leaf knitting machine is configured by arranging a plurality of conveyors in parallel and adjusting the distance between the conveyors and the distance between the leaf knitting needles. Further, the present invention comprises two rod bodies arranged in parallel at a predetermined interval, and a connecting fitting provided between the end portions of both rod bodies, wherein the connecting fitting has one base end portion. Is rotatably attached to the end of the rod, and the other end is detachably locked to the end of the other rod.

[0008]

According to the above-mentioned means, the leaf cigarette hanging device is placed on the conveyer conveyor in a disassembled state, and the leaf tobacco placed on the conveyer is disassembled. It moves at a constant speed with the operation of.
At the same time, a plurality of leaf knitting needles installed at intervals in a direction orthogonal to the conveyor conveying direction weave (sew) the moving leaf tobacco on the conveyor. As a result, the leaf cigarettes placed on the transport conveyor in a discrete manner are put together by a plurality of stitches that are knitted in parallel at predetermined intervals.

[0009] The transport speed of the above-mentioned transport conveyor and the weaving speed by the leaf knitting needles (the number of reciprocations of the needles per hour)
By adjusting and respectively, the speed ratio between the two is relatively changed, and the knitting pitch by each leaf knitting needle is changed. By adjusting the transport speed of the transport conveyor and the weaving speed of the leaf knitting needles in proportion to increase or decrease, the feed rate of leaf tobacco can be increased without changing the knitting pitch of the leaf knitting needles. Further, the leaf tobacco hanging device for leaf knitting of the present invention is placed on the leaf tobacco placed in a disassembled state on the conveyor, and when the braided tobacco is suspended, the stitches are on the rod of the tobacco hanging device. Place both rods in parallel where they are located. Then, leaf tobacco is further placed on the rod body.

When knitting with a leaf knitting needle, the connecting metal fittings for connecting both ends of the rods are detached from the tip side and rotated to a position where they do not intersect the stitches. After the leaf knitting is completed, the ends of the rods, which have been turned, are locked to the ends of the rods, thereby connecting the ends of the rods to be integrated. Therefore, the two rods whose both ends are connected by the connecting metal fittings are in a state of being positioned on one side of the stitch knitted into the leaf tobacco, and the bar-knitted leaf tobacco can be suspended by the rods.

[0011]

As described above, the leaf knitting machine for leaf tobacco according to the present invention has a plurality of leaf tobaccos placed in a discrete state on the conveyor and arranged at intervals in the direction orthogonal to the conveying direction. Since it is knitted by the leaf knitting needles, it is possible to collect the loose leaf tobacco in a suspendable state in the drying chamber by a plurality of stitches knitted in parallel at equal intervals. Therefore, it is possible to shorten the leaf tobacco placing work, which conventionally takes a lot of time and labor, and significantly improve the efficiency of the leaf knitting work. Leaf tobacco knitted in this way can likewise be dried in a conventional drying chamber.

In the case where the conveying speed of the conveyer conveyor and the knitting speed by the leaf knitting needles are adjustable, the knitting pitch by each leaf knitting needle can be changed to adjust the size of the stitches. Become. Further, the conveying speed of the conveyer conveyor and the knitting speed by the leaf knitting needles that are configured to be adjustable in proportion to increase or decrease the leaf tobacco feeding speed without changing the knitting pitch by the leaf knitting needles, that is, the working speed of the leaf knitting. Can be raised.

In the leaf tobacco hanging device for leaf knitting of the present invention, when leaf knitting is carried out using the above-mentioned leaf knitting machine, about half the amount of leaf tobacco required for one hanging device is uniformly distributed on the conveyor. Side-by-side placement of a pair of suspenders at a predetermined place on top of them, and the remaining half of the leaf tobacco is evenly arranged from above, and then the leaf knitting work is performed, whereby the stitched portion of the leaf tobacco is knitted by the leaf knitting. It is possible to mount two rods along the edge of the bar, which allows the leaf cigarettes that have been knitted by leaf knitting to be held and suspended as they are. Also,
When performing leaf knitting with the leaf knitting needles, the connecting metal fittings can be rotated to a position that does not intersect the passing position of the leaf knitting needles, so there is no problem that the connecting metal fittings interfere during the leaf knitting. .
