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 a fresh leaf in a large-scale drying facility for leaf tobacco and picking and drying dry leaves.

[0002]

2. Description of the Related Art In general, hanging of fresh leaves in a dryer for leaf tobacco drying is carried out by first hanging a large number of fresh leaves on a hanger such as a binder and then hanging the leaves in a drying chamber of the dryer in multiple stages. From the leaf knitting work place where you can hang fresh leaves on a hanger with a leaf knitting machine etc., carry the hangers that have finished the leaf knitting and hang a large number of fresh leaves one by one to the drying room, and sequentially mount them on the hanging rack rails of the drying room. I am doing it. Similarly, in the dry leaf unloading after drying, the hangers are sequentially picked up one by one from the hanging rack rails of the drying room and transported to the removing work place where the dry leaves are removed.

[0003]

However, in order to mount or unload the hanger on the hanging shelf rail at the uppermost stage of the drying room, a step or the like must be used, and the hanger suspends a large amount of leaf tobacco. 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 operations associated with hanging fresh leaves and picking and drying dry leaves in the drying of leaf tobacco are conventionally heavy labor,
Although it requires a lot of labor, hiring workers is becoming difficult due to soaring worker wages and lack of labor due to various social factors today, and labor saving is strongly demanded. There is. The present invention has been made in view of the current situation, and it is an object of the present invention to drastically save labor in a series of operations such as hanging of fresh leaves and unloading of dry leaves accompanying drying of tobacco.

[0005]

In order to achieve the above object, in the labor saving system for leaf tobacco drying work of the present invention, the entrances are arranged in a horizontal row with the entrances facing in the same direction, and a pair of left and right hangings are provided on the left and right side walls respectively. A plurality of drying chambers having a plurality of loading rails, a track installed on the floor surface in front of the drying chambers in parallel with the rows of the drying chambers, and a pair of left and right having substantially the same spacing as the spacing of the hanging rails of the drying chambers. An elevating rack which is provided with a guide rail so as to be able to move up and down and is provided with traveling means so as to be able to travel on a track, and a plurality of racks are arranged in parallel with the track on the floor surface opposite to the drying chamber across the track. Equipped with a temporary suspension rack that has a pair of left and right guides that are provided at approximately the same intervals as the guide rails of the elevating rack, and a hanger that is formed in a box frame shape and suspends leaf tobacco at its upper left and right ends. Hanger A hanging rack that has a receiving portion and is slidably mounted on the guide portion of each temporary hanging rack, and preferably a leaf-filled rack that is provided for each temporary hanging rack and arranged in the vicinity of the temporary hanging rack. And a workbench.

[0006]

[Operation] In the labor saving system for the leaf tobacco drying work configured as described above, the hangers clogged with the leaf workbench are temporarily suspended in the suspension rack mounted on the temporary suspension rack arranged near the workbench. Then, the hanging rack is transferred to the elevating rack and conveyed to the drying room, and the guide rails of the elevating rack are moved up and down, and the hanging racks are collectively hung on the required hanging rails of the drying room. In addition, the dried leaves are lifted from the drying chamber by the lifting rack and collected together with the hanging rack, and transferred to the temporary hanging rack near the workbench.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The figure shows an example of the system of the present invention in a common drying facility. In the figure, A indicates a conventionally known drying apparatus in which several to ten or more of them are arranged in a row in a row so that their entrances are oriented in the same direction. Each of the drying chambers A is provided with a pair of left and right leaf tobacco suspension rails 1 extending inward from the entrance in a plurality of stages, for example, three stages, on the inner surface of the side wall of each drying chamber A.

A track B is provided on the floor surface in front of the drying chamber A in parallel with the rows of the drying chamber A. The track B is composed of a pair of parallel rails and is laid on the floor of the facility close to the entrance of the drying chamber A. On the track B, an elevating rack C described later is movably arranged.

Further, an appropriate number of temporary racks D, for example, a number corresponding to the number of drying chambers A, are arranged in parallel with the track B on the floor opposite to the drying chamber A with the track B interposed therebetween. One leaf-packing work table E is arranged behind the temporary hanging rack D for each hanging rack D. This leaf filling work table E
Is a leaf tobacco hanger 18, for example, a stuffing work for attaching fresh leaves to a binder in a hanging manner, a work for removing leaves for removing dried leaves from the hanger, a bundling work, and a sorting work. It may be a conventionally known sewing machine leaf knitting machine for mechanically knitting fresh leaves.

The track B and the drying chamber A, and the track B and the temporary suspension rack D are arranged close to each other so that the elevating rack C moving on the track B almost comes into contact with the rack C when it moves in front of it. . In addition, the space behind the leaf filling work table is a raw leaf storage area, and the raw leaf placement table F is arranged in the drawing.

The lifting rack C described above is assembled by a steel rod or the like into a box frame shape or a turret shape with both front and back directions open.
A pair of left and right axles 3 extending in the normal direction and having wheels 2 at both ends are rotatably attached to the lower surface thereof.
It is placed on the track B via these wheels 2. One of the axles 3 is connected to a traveling motor 4 attached to an appropriate location of the lifting rack C via a chain 5 and is rotationally driven by the motor 4.
Therefore, the lifting rack C can be moved left and right on the track B by driving the motor 4.

The lifting rack C has a pair of upper and lower rotating shafts 6a and 6b extending in the normal direction on the left and right side surfaces, and the upper rotating shaft 6a is located at an appropriate place on the lifting rack C, for example. The chain drive motor 7 attached to the upper surface is connected via the chain 8 to
It is designed to be driven to rotate by. Further, two endless chains 9 are stretched in parallel with each other on the pair of upper and lower rotary shafts 6a and 6b with an appropriate interval therebetween. The chain drive motors 7 are separately provided for the left and right rotary shafts 6 and operate in synchronization with each other.

In the two endless chains 9 arranged on the same side surface of the lifting rack C, the same number of guide rails 10 as the suspending rails 1 of the drying chamber A are vertically spaced from each other. The suspension rails 1 are arranged at the same vertical intervals as each other, and the suspension rails 1 and 2 are provided so that the one provided on the left side surface portion and the one provided on the right side surface portion are at the same height position. Therefore, the lifting rack C can be lifted and lowered by driving the chain driving motor 7 while keeping the left and right guide rails 10 at the same height position. The suspension rail 1 and the guide rail 10 are formed to have an L-shaped cross section.

The temporary suspension rack D has its front and rear and upper portions opened by a pair of left and right side frames 11 framed in a square shape by a steel rod and the like, and a bottom frame 12 connecting the side frames 11 to each other in parallel at their lower ends. It is assembled in a box shape, and a pair of guide portions 13 having a cross-section L direction are provided at the upper ends of the left and right side frames 11 so as to face each other in a rail shape extending in the front-rear direction. A suspending rack G is slidably mounted on the guide portion 13 of the temporary suspension rack D.

The hanging rack G includes a pair of left and right holding frames 14
And a fixing rod 15 for fixing the left and right holding frames 14 so as to stand upright in parallel with each other at a predetermined interval at the upper end of one side end of the holding frame 14 and other holding frames 14. The lower side end is formed into a flat rectangular frame shape by a holding rod 16 which is detachably mounted across the holding frames 14 and the holding frame 14 is formed by connecting the lower end portion of an upper frame plate 14a made of a metal plate material. Roll it up to form a tubular pipe receiver 17,
By inserting both ends of the presser frame 14b formed by bending a metal rod into a square shape to 17, presser frame 14b
Is hung vertically on the upper frame plate 14a so as to be rotatable and foldable. Then, the fixed rod 16 is attached and fixed across the upper frame plates 14a of the pressing frame 14 facing each other.

Further, a hanger receiving portion 19 for locking the leaf tobacco hanger 18 is formed on the upper frame plate 14a of the holding frame 14 so as to project horizontally outward from the upper end of the frame plate 14a. Rollers 20 which rotate about a vertical axis are attached to the side at appropriate intervals such that a part of the peripheral edge thereof protrudes from the tip 19 of the hanger receiving portion, and the rollers 20 are further provided.
Rollers 21 that rotate about a horizontal axis are installed inside at appropriate intervals.

On the other hand, the holding rod 16 is constructed by bending both ends of a metal rod at right angles, and holding the both ends of the holding frame facing each other.
The 14 presser frames 14b are hooked and mounted between the frames 14b to prevent the presser frames 14b from spreading outward.

Thus, such a hanging rack G has rollers 20, 21.
The hanger receiving part 19 via the guide part of the temporary rack d
By being locked to 13, the mounting frame 14 is mounted in the temporary hanging rack D so that the side where the pressing frame 14 is fixed by the fixing rod 15 faces the drying chamber A installation side. At this time, the roller 20 that rotates around the vertical axis
The rollers 21 rotating about the horizontal axis come into contact with the vertical plane of the L-shaped guide portion 13 of the temporary suspension rack D, respectively, on the horizontal plane.

In the labor saving system for the leaf tobacco drying work constructed as described above, the hanger 18 is filled with the leaves on the hanger 18 in the same manner as in the conventional work, and the hanger 18 after the leaf filling is filled with the hanger 18. The suspension rack G is mounted on a temporary suspension rack D arranged near the work table E. At this time, if the holding rod 16 of the suspension rack G is removed, the hanger 18
Easy to hang. When the predetermined number of hangers 18 have been hung on the hanging rack G, the holding rod 16 is pressed onto the rack G.
Hold it so that the fresh leaves hung from the rack do not protrude from the rack G.

The elevating rack C travels on the track B and is sequentially stopped in front of the temporary suspension rack D that has been suspended in the suspension rack G, and the suspension rack G that has been suspended is temporarily suspended. Guide rail 10 from rack D to lifting rack C
Transfer to. Transfer of the suspended rack G from the temporary suspension rack D to the guide rail 10 of the lifting rack C is performed as follows.

That is, the lifting rack C in front of the temporary suspension rack D.
Guide rail by operating the chain drive motor 7
A required pair of 10 is adjusted to the same height position as the guide portion 13 of the temporary suspension rack D, and in this state, the suspension rack G is pushed and moved to the lifting rack C side to be transferred to the guide rail 10 of the lifting rack C. . At this time, the hanging rack G is a hanger receiving part.
19 Guide part 1 of temporary suspension rack d by rollers 20 and 21 on the back side
3, slide on the guide rail 10 of the lifting rack c to easily transfer to the lifting rack C side.

The elevating rack C, in which the hanging racks G have been transferred to all the guide rails 10 in this manner, travels on the track B to the front of the required drying chamber A, and the guide rails 10 are moved.
Is adjusted so as to match the height position of the suspending rail 1 of the drying chamber A, and the suspending rack G on the guide rail 10 is transferred to the corresponding suspending rail 1 of the drying chamber A. Also in this case, the hanging rack G can be easily moved by the rollers 20 and 21 just by moving the hanging rack G to the drying chamber A side as in the case of transferring the hanging rack G from the temporary hanging rack D to the lifting rack C. Transfer to the suspension rail 1 side of the drying room A.

By repeating this, the hangers 18 packed with the leaves on the stuffing work table E are sequentially suspended in a predetermined drying chamber A. Then, this work is repeated until the suspension in all the drying chambers A is completed. When drying in the drying chamber A is completed and dry leaves are unloaded, the work is performed in the reverse order of the above steps, and the dry leaves are unloaded to the leaf filling worktable E for bundling and sorting. Do the work.

Reference numeral 22 in the drawing is a stopper for holding the hanging rack G so that it does not slip off the guide rail 10, and a notch is formed in a part of the guide rail 10 to fold it up in a chevron shape to form a spring shape. Therefore, when the hanging rack G is loaded and unloaded on the guide rail 10, its elasticity prevents the hanging rack G from being retracted downwards and hindering the loading and unloading work.

[0025]

[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 first hung on the suspension rack mounted on the temporary suspension rack that is located near the workbench. , This hanging rack can be carried to the drying chamber by the elevating rack, and the guide rails of the elevating rack can be raised and lowered to be hung together with the racks on the required hanging rails in the drying chamber. You can hang the dry leaves in the room on the lifting rack and take them down together, and carry them to the temporary hanging rack near the workbench as it is, and bring one hanger with hanging leaf tobacco to the workbench and the drying room. There is no need to go back and forth between the steps many times, or to use a hanger to repeatedly go up and down the platform. 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.
