Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a labor-saving system for a series of operations such as hanging fresh leaves and unloading dry leaves in a large-scale leaf tobacco drying facility.

[0002]

2. Description of the Related Art In general, hanging of fresh leaves in a dryer in leaf tobacco drying is performed by first packing a large number of fresh leaves in a hanger such as a binder and suspending them in a drying chamber of the dryer in multiple stages. From the packing place where the leaves are packed in a hanger using a leaf knitting machine or the like, one hanger, which has finished packing and hangs a large number of fresh leaves, is carried to the drying room one by one and mounted on the hanging rails of the drying room one by one. I am doing it. Similarly, for dry leaf unloading after drying, each hanger is sequentially unloaded from the hanging rail of the drying chamber and taken to the removal work place (most of which also doubles as a leaf filling work place), where it is dried from the hanger. The leaves are removed.

[0003]

However, in order to mount or unload the hanger on the hanging rail at the uppermost stage of the drying chamber, a step or the like must be used, and a hanger with a large amount of leaf tobacco hung. You have to keep going up and down the basin many times. Also, in large-scale facilities such as shared drying facilities, there are many cases in which the dryer is placed far away from the place where fresh leaves are sandwiched or knitted into hangers, or dry leaves are removed from the hangers. I have to go back and forth many times with a hanger with hanging tobacco. Moreover, the hanger that hangs a lot of tobacco is very heavy.

[0004] As described above, a series of work involved in hanging fresh leaves and drying and unloading dry leaves in the process of drying tobacco leaves has conventionally been a heavy labor and requires a lot of manpower, but the wages of workers due to various social factors today. It is becoming difficult to hire workers due to soaring labor costs and labor shortages, and there is a strong demand for labor saving. The present invention has been made in view of the present situation, and it is an object of the present invention to significantly save labor in a series of operations such as hanging of fresh leaves and unloading of dry leaves, which accompanies drying of tobacco leaves.

[0005]

In order to achieve the above object, in the labor saving system for leaf tobacco drying work of the present invention, a plurality of drying chambers and work benches respectively installed in appropriate places in a drying facility,
A lifter that is arranged in the vicinity of each workbench and has at least one pair of left and right temporary suspension rails extending in the right and left directions on the left and right side surfaces of the machine body, each of which has both front and back surfaces open, so as to be vertically movable. , A pair of left and right guide rails extending in the front-back direction at substantially the same intervals as the lifter temporary suspension rails are provided on the left and right side surfaces of the machine body with both front and back surfaces open, and wheels are provided at the bottom of the machine body. It is provided with a large number of transport racks which are provided so that they can be moved in any direction and taken in and out of the drying chamber.

[0006]

[Operation] In the labor saving system for the leaf tobacco drying work configured as described above, the hanger that is filled with the leaf workbench is temporarily hung up on the temporary suspension rail of the lifter arranged near the workbench, and then the transport rack. To the front of the lifter and, if necessary, raise the temporary lift rail of the lifter to the height of the required guide rail of the transport rack, and slide the hanger of the temporary suspension rail to the guide rail of the transport rack to perform the required drying. Carry it to the room and put it in the drying room with the transport rack to dry. After drying, take the dried leaves together with the transport rack out of the drying chamber and carry them to the required lifter.If necessary, lift the temporary lifting rail of the lifter to adjust the temporary hanging rail to the height of the guide rails and hangers. Slide it from the guide rail of the transport rack to the temporary suspension rail of the lifter. Then, while moving the temporary suspension rail to a workable height, unload the hanger on the workbench.

The motor 5 is separately provided for the rotary shaft provided on the left side surface and the rotary shaft provided on the right side surface, and operates in synchronization with both.

The temporary suspending rails 4 are provided at the same height position on the left side surface and the right side surface, and three pairs of upper and lower sides are provided as a set. Each temporary suspending rail 4 has a length of the hanger a. The distance is approximately equal to the height. The number of sets of the temporary suspension rails 4 is provided so as to correspond to the number of sets of guide rails 8 provided in a plurality of stages on the transport rack D described later.
It is also optional to form a group or the like. Each of the temporary suspension rails 4 has a vertical interval corresponding to the vertical interval between the groups of the guide rails 8. The temporary suspension rail 4 has an L-shaped cross section.

The transport rack D is made of a steel rod 9 and the like and has a body D '.
Are assembled in a box-frame shape with at least open in both the normal and back directions, and wheels 10 such as casters are attached to the four corners of the lower surface of the box so that they can be moved in any direction. The depth dimension is slightly smaller than the front dimension and the height dimension, and the depth dimension is formed so as to be one half to one half of the depth dimension of the drying chamber A. Therefore, this transport rack D can be taken in and out of the drying chamber. Further, on the left and right side surfaces of the transport rack D, there are three guide rails 8 extending in the front-back direction, that is, the depth direction.
It is provided in a step. The guide rails 8 are L-shaped in cross section, and the interval between the pair of guide rails 8 is substantially the same as the interval between the pair of temporary suspension rails 4 of the lifter C.
The number of such transport racks D accommodated in at least all the drying chambers A in the facility and the number required to fill the inside of each drying chamber A are prepared.

In the labor saving system for the leaf tobacco drying work configured as described above, the hanger a is filled in each leaf-packing work table B by the same work as in the conventional case, and the hanger a which has been filled is leaf-packed. Hang it on the temporary suspension rail 4 of the lifter C arranged near the work table B.

At this time, the lifter C operates the motor 5 so that the uppermost temporary suspension rail 4 is first moved to a height position where it is easy to suspend, and then the middle temporary suspension rail and the lowermost stage are suspended. The suspending work is performed while moving the position of the temporary suspension rail in order to a height suitable for the suspending work.

Further, when the hanger a is hung on each of the temporary suspension rails 4 of the lifter C, the temporary suspension rails 4 are mounted on the temporary suspension rails 4 as shown in FIG.
The hanging rack F as shown in (1) is mounted and placed in advance, and the leaf-filled hanger a is hung on the temporary hanging rail 4 via the hanging rack F.

As shown in FIG. 6, the hanging rack F is attached to a pair of left and right holding frames 11 and is attached across the holding frames 11 at the upper end of one side of the holding frames 11. A fixed rod that is fixed so as to stand upright in parallel at a predetermined interval.
12 and a presser bar 13 which is detachably mounted across the presser frame 11 at the lower end of the other side of the presser frame 11, and is formed into a flat rectangular frame shape. The upper part of the presser frame 11 has a hanger a.
A hanger receiving portion 14 that locks the hanger is formed so as to project horizontally outward, and a roller 15 that rotates about a vertical axis is formed below the hanger receiving portion 14 so that a part of the peripheral edge thereof is part of the hanger receiving portion. 14
Rollers 16 are mounted at appropriate intervals so as to project from the tip end, and rollers 16 rotating about a horizontal axis are further mounted inside the rollers 15 at appropriate intervals. The suspension rack F locks the hanger receiving portion 14 with the temporary suspension rail 4 of the lifter C via the rollers 15 and 16 so that the side where the pressing frame 11 is fixed by the fixing rod 12 faces the inner side. A roller 15 mounted on the temporary suspension rail 4 of the lifter C and rotating about a vertical axis is provided on a vertical surface of the L-shaped temporary suspension rail 4 of the lifter C, which rotates about a horizontal axis.
16 are in contact with the horizontal plane, respectively.

When a predetermined number of hangers a have been suspended on one set or all of the temporary suspension rails 4, the transport rack D is moved to a position facing the lifter C on which the suspension has been completed. The hanger a is suspended from the temporary suspension rail 4 to the guide rail 8 of the transport rack D and the rack F is collectively transferred. Temporary suspension rail 4 of the lifter C above
Rack F hanging from guide rack 8 to guide rail 8
The transfer of is performed as follows.

That is, after the transport rack D is moved to correspond to the lifter C, the motor 5 of the lifter C is operated as necessary to set a required set of the temporary suspension rails 4 to a required guide rail of the transport rack D. It is adjusted to the same height position as 8, and in this state the hanging rack F is pushed and moved to the side of the transport rack D, and this is slid on the guide rail 8 of the transport rack D. At this time, the hanging rack F can be easily moved from the lifter C to the transport rack D by sliding on the temporary suspension rail 4 and the guide rail 8 of the transport rack D by the rollers 15 and 16 on the back side of the hanger receiving portion 14. it can.

In this way, the transport rack D in which the hangers a have been transferred to the guide rails 8 together with the hanging rack F is moved to the front of the required drying chamber A, and is pushed into the drying chamber A as it is to be stored inside.

By repeating this, the hangers a, which are packed in the packing work table B, together with the transport rack D are sequentially dried in a predetermined drying chamber A.
Hang on. This operation is repeated until all the drying chambers A are filled with the transport racks D in which the hanger a with leaves is suspended. Then, after the suspension in all the drying chambers A, drying is performed in a usual manner.

When the drying in the drying chamber A is completed and the dry leaves are to be unloaded, the work is carried out in the reverse order of the above steps, the transport rack D is pulled out from the drying chamber A, and the lifter C is moved.
Then, the temporary suspension rack F is moved to the temporary suspension rail 4 of the lifter C, and the lifter C is operated as necessary to move the temporary suspension rail 4 to a height at which work can be easily performed, and the hanger a is unloaded. Then, the work of removing leaves, bundling, and sorting is performed on the leaf packing work table B.

In the embodiment described above, the leaf-filled hanger a is hung on the temporary suspension rail 4 of the lifter C via the suspension rack F.
It is also possible to hang the hanger a directly on the temporary suspension rail 4 of the lifter C without using. Further, the temporary suspension rails 4 provided on the lifter D are only one set regardless of the number of steps of the guide rails 8 of the transport rack D, and the hanger a temporarily suspended on the temporary suspension rails 4 by raising and lowering the temporary suspension rails 4 is required. The lifting of the guide rails up to 8 heights and the transfer to the guide rails 8 may be repeated for each guide rail 8.

[0022]

[Effect] Since the present invention is configured as described above, when suspending fresh leaves, the hanger that has been filled with the leaf filling workbench is hung up temporarily on the temporary suspension rail of the lifter arranged near the workbench, and when the required number has been collected. By operating the lifter and moving them all together to the guide rails at the required height position of the transport rack, they can be transported to the drying chamber, and can be stored in the drying chamber together with the transport rack for drying. With the ability to transport dry leaves suspended in a rack as they are to the transport rack to the front of the lifter near the workbench, transfer them to the temporary lifting rail of the lifter for unloading, and have one hanger for hanging the leaf tobacco. There is no need to go back and forth between the workbench and the drying room many times, and to repeatedly go up and down the platform with a hanger. Therefore, a series of operations involved in hanging fresh leaves and drying and unloading dry leaves during the tobacco drying process can significantly reduce the labor and the number of workers can be significantly reduced.
