Description of the Related Art In the process of drying leaf tobacco, a needle rack for drying leaf tobacco (hereinafter referred to as a needle rack) is stuffed with raw leaves, a step of hanging the needle rack after stuffing raw leaves into a drying chamber, and a process after drying the leaf tobacco. There is an unloading process to pull out the needle rack from the drying room. This needle rack is provided with an upper needle fixing frame to which a plurality of needles are fixed and a lower needle receiving frame into which the tips of the needles fit, and a leaf tobacco is sandwiched between these upper and lower frames to form a leaf portion of leaf tobacco. Also, the branch handle is pierced and fixed by a needle, and both ends of both members are connected and fixed by a metal fitting or the like.

Conventionally, each of these steps has been manually performed, which requires a considerable amount of heavy labor for the worker and makes it difficult to improve work efficiency. For example, when hanging a rack after leaf filling in a drying chamber, it is difficult to hang it while keeping the rack in a horizontal state, and since the rack is heavy, the rack rails in the drying chamber are misaligned with the rack. As a result, much time and effort have been involved in loading the racks onto the rack rails. In addition, after filling the needle racks with leaves on the leaf filling table, the racks are carried to the drying room and loaded on the shelf rails, then returned to the leaf filling table and the next rack is filled with leaves. It was In other words, the worker alternates between the leaf filling work and the rack hanging work while moving between the leaf filling base and the drying chamber, resulting in an intermittent work flow and poor work efficiency. . Further, when unloading the dried tobacco leaf, it requires a great deal of labor, especially for unloading the rack placed on the upper rail of the drying chamber.

And the suspension rail 14 are connected to each other. Specifically, in the structure shown in FIG. 3, the auxiliary rail 15 is manually collapsed and connected by utilizing the Torg effect of the spring 16, and the tow string 10 is pulled to move the needle rack 2 to the suspension rail 14. Here, the Torg effect will be described. As shown in FIG.
By attaching the coil spring 16 on a straight line (that is, on the rotation axis and the point of action of force) straddling the rotation axis of the auxiliary rail 15, the biasing force of the coil spring 16 acts on the auxiliary rail 15 in any of the standing and falling states of the auxiliary rail 15. This is an effect that balances in a fixed state in any direction (vertical or horizontal direction).
Therefore, by manually pushing down or lifting the auxiliary rail 15, the shelf rail 6 and the hanging rail 14 can be easily held in the connected and unconnected states.

In the case of using the link mechanism shown in FIG. 5, when the link rod 18 is pulled, the auxiliary rail 15 falls down to be connected to the suspending rail 14. In addition, FIG.
7 and FIG. 7, the lifting rail 14 on the lifter 5 side is
Since the roller 2e of the needle rack 2 is supported by the intermediate roller 17 extending from the end of the needle rack 2 until it gets on the shelf rail 6, the needle rack 2 can be racked without the auxiliary rail 15 as described above. It is possible to move between the rail 6 and the hanging rail 14. The various bridging means described above enable smooth movement of the needle rack 2 between the shelf rail 6 and the hanging rail 14 during both the hanging work and the unloading work of the needle rack 2.

As described above, the present apparatus uses the rack lifter 5
The needle rack 2 is loaded into the shelf rail 6 in the drying chamber 4 by using. Therefore, the rack hanging work can be mechanized or labor-saving, and the heavy labor for lifting the heavy and long needle rack 2 can be released, and even a woman or an elderly person can perform the hanging work alone. Further, a rack holding rod 7 for temporarily holding the upper frame 2a of the needle rack 2 before the leaf packing is provided so as to be located right above the front of the leaf packing base 3, or the upper frame 2a of the needle rack 2 can be removed from the dried tobacco leaf. It is possible to provide a pipe mounting portion 9 for placing the leaf pressing pipe 8 used when removing the needle, and to smoothly move the needle rack 2 from the drying chamber 4 to the suspending rail 14 of the rack lifter 5. By providing the bridge portion, the worker can smoothly perform the work without moving the needle rack 2 for transportation.
