BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for drying tobacco, which is used in a stage prior to storing a large number of leaf tobaccos in a dryer for restraining and drying the leaf tobacco, and in which the tobacco is kept suspended in the dryer. It is about.

[0002]

2. Description of the Related Art Harvested leaf cigarettes are bundled on a workbench and confined by needles of a hanging rack, and are stored in a multi-stage state in a state of being hung in a dryer in order to dry many sheets at a time. (For example, JP-A-8-173127). The suspension rack for that purpose consists of a receiving rack and a rack with needles fixed thereon. When bundling leaf tobacco, a workbench is used. A receiving rack is placed on the workbench, and a predetermined number of leaf tobaccos are placed on the receiving rack so that the operator has a petiole. When a predetermined number of leaf tobaccos are bundled on the receiving rack, the needle material is stuck on the leaf tobacco from above using a rack with a needle and restrained.
The receiving rack and the rack with needles fixed thereon are fixed by hook-type fasteners at both ends in the longitudinal direction of the hanging rack. The hook-type fasteners are provided on the upright frames at both ends of the receiving rack, and engage with the rack with needles. When the leaf tobacco is bundled and restrained in the hanging rack, it is sent to the dryer, and is stored in the dryer in multiple stages and dried. Since the suspension rack at this time is as heavy as several tens of kilograms, a lifter is used when sending the suspension rack to the dryer. In the present invention, devices such as a hanging rack, a work table, and a lifter used in the series of operations are collectively referred to as a device for drying tobacco.

[0003]

Since the hanging rack of the apparatus for drying tobacco has a large number of needles in the rack with needles, it is very difficult to attach one by one to the upper rail of the rack with needles during manufacturing. there were. In addition, when leaf tobacco is bundled on the receiving rack during use, there is a work to stab the needle material of the rack with the needle into the leaf tobacco from above and restrain it.Both ends of the rack with the needle are combined with both ends of the receiving rack. It is not easy, and the hook-type fastener (fastening fitting) for fixing the rack with the needle and the receiving rack integrally is set up on both ends of the receiving rack as proposed in, for example, Utility Model Registration No. 3012862. There was no choice but to provide a recess in the upright frame. Therefore, there were some surfaces where it was difficult to remove the hook-shaped fastener from the concave portion of the opening / closing handle when opening / closing the hook-shaped fastener.

[0004] Next, on a workbench in which leaf tobacco in a leaf tobacco drying apparatus is bundled on a receiving rack of a hanging rack, or after drying, the leaf tobacco is removed from the hanging rack, the operator aligns the petiole portions. It was difficult, and leaf tobacco sometimes fled forward and fell.

Further, a hanging rack containing a large number of leaf tobaccos is stored in a drying machine in a plurality of stages and dried.
Since the weight is as heavy as several tens of kilograms, a lifter is used when housed in a dryer. This has a structure in which rails are provided on both sides of the frame-shaped main body from the worker side to the dryer, and the rollers of the hanging rack roll on this rail to transfer to the rail provided on the dryer side. I have. It is difficult to make contact between the lifter side rail and the dryer side rail, but it is very difficult for the rollers of the suspension rack to move from the lifter side rail to the dryer side rail. This is a drawback in the tobacco drying operation.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems at the time of manufacture and use of a hanging rack, a workbench, and a lifter in a device for drying tobacco, thereby reducing the cost of the device for drying tobacco and improving the work efficiency.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a plan view of a hanging rack in a leaf tobacco drying apparatus of the present invention, FIG. 2 is a front view of the hanging rack, and FIG. 3 is a right side view. FIG. 4 is an enlarged plan view of the standing frame portion. 5 is a plan view of only the receiving rack among the members constituting the hanging rack, FIG. 6 is a front view of the receiving rack, and FIG. 7 is a right side view. FIG. 8 is a plan view of only the rack with needles among the members constituting the hanging rack, and FIG. 9 is a front view of the rack with needles.

The leaf tobacco hanging rack 10 in the leaf tobacco drying apparatus of the present invention comprises a receiving rack 1 and a rack 2 with needles fixed thereon. The rack with needles 2 is supported by the standing frames 3 at both ends of the receiving rack 1. In the present invention, each of the upright frames 3, 3 at both ends is formed in a substantially flat surface 3a in the middle, and both edges are formed in an outward channel shape. The term “outward channel shape” here means that the folded edges 3b, 3b of the upright frames 3, 3 at both ends are symmetrical at the right and left upright frames 3, 3 and not outward but not inward as shown in FIG. It means that it is provided in the direction. The tips 3c, 3c of the folded edges 3b, 3b are further folded in a lip shape substantially parallel to the flat surface 3a to form guide grooves 4, 4 on both edges of the upright frame 3. Guide rods 5, 5 at both ends of the rack with needles 2 are inserted into the guide grooves 4, 4 from above.

FIGS. 5 to 7 show a receiving rack 1 of the hanging racks 10.
The characteristic feature is that the guide grooves 4, 4 are formed at both edges of the upright frame 3 described above, and a space can be secured outside both ends, so that the needles are provided on the flat surface 3a. The hook type fastener 6 for integrating with the attached rack 2 has been provided. The hanging rack 10 is provided with rollers 11 on one side of the upper and lower sides that run on a rail to feed the tobacco into the dryer while hanging it and to take it out after drying, but if a hook type fastener is attached, it will protrude conventionally. The main drawback was that a space could be secured outside of both ends, and the hook-type fastener was settled on the flat surface 3a inside the space, which solved the conventional difficulties.
The formation of the guide grooves 4, 4 at both edges of the standing frame 3 of the receiving rack 1 results in increased strength and rigidity. The steel plate-shaped bottom plate 7 of the receiving rack 1 of this embodiment is provided with ribs 7a and a large number of ventilation holes 7b which are parallel to the longitudinal direction, and has a porous structure in order to enhance the drying efficiency. The rib 7a prevents this from happening. As a result, the weight reduction and the drying efficiency could be improved.

This increases strength, improves work efficiency and reduces costs, as compared to the conventional left and right needles that are screwed to one, and also allows the needles to come loose during use. Thus, the effect of improving durability was obtained.

The receiving rack 1 of the hanging rack 10 is placed on a work table, and the operation of aligning the petiole portions of the tobacco on the bottom plate 7 is performed. The work table 12 of the present invention is shown in FIG. 10 (front view) and FIG. 11 (side view). In FIG. 10, the left side in the drawing shows the appearance seen at the time of work, and the right side in the drawing shows a state where the rotary work table 13 is inverted. In this worktable 12, a rotary worktable 13 is rotatably supported on left and right bearings 15, 15 on a base 14 provided with movable wheels at a lower portion. Rails 16, 16 are provided on the rotating worktable 13 at right and left sides in a right angle direction. When the work of aligning the leaf tobacco is performed, the rail 16 stands up obliquely upward as shown in FIG. In this state, the work is performed by arranging the receiving rack 1 so that the rollers 11 of the receiving rack are in contact with the rails 16.

At this time, in the present invention, the rotating worktable 13 can be fixed so that the worker side (the left side in FIG. 11) is lowered. A side plate that supports the rotating worktable 13 for that purpose
A support pin 18 that supports the bottom of the rotary worktable 13 is held at 17 so as to be removable. When a predetermined number of leaf tobaccos are stacked on the receiving rack 1, the guide rods 5,
When the guide material 5 is inserted into the guide grooves 4 on both sides of the stand frame 3 of the receiving rack 1 and lowered, the needle material 9 stabs and restrains the leaf tobacco from above. Thereafter, the receiving rack and the rack with needles are fixed by hook-type fasteners at both ends in the longitudinal direction of the hanging rack. When this work is completed, it is sent to the lifter, but since the total weight of the hanging rack 10 and the leaf tobacco is several tens of kilograms, it is sent using the rail 16 without human power. For this purpose, the rotating worktable 13 is moved clockwise in FIG.
Rotate degrees. The receiving rack 1 holding the leaf tobacco with the needle material stabbed on the rail 16 which has become substantially horizontal moves to the lifter by the rotation of the roller 11. The provision of the contact plate 19 on the worker side of the rotating worktable 13 and the

According to the present invention, the above-mentioned problems at the time of manufacture and use of the hanging rack, work table and lifter in the apparatus for drying tobacco are solved. That is, it is as follows.

In the hanging rack, the standing frames at both ends of the receiving rack for supporting the rack with needles are formed in the shape of an outward channel having a substantially flat middle surface, and a hook-type fastener for the rack with needles is provided on the flat surface. The hook operation or the release operation of the hook-type fastener is easy. Also, since both edges of the standing frame could be used as guide grooves for the rack post with needle,
Pushing of the support, that is, the operation of inserting a needle into leaf tobacco, can be performed smoothly. In addition, since the bottom plate of the receiving rack is provided with ribs parallel to the longitudinal direction and a large number of ventilation holes, the ribs can be prevented from becoming soft, and the weight can be reduced and the drying efficiency can be improved.

A large number of needles having a substantially U-shape crossing over the horizontal rail of the rack with needles are welded by spot welding, so that the work efficiency is reduced as compared with the conventional one-point screwing. And the cost can be reduced, and the needle part does not come loose during use, and the effect of improving the durability is obtained.

Maintaining the work surface of the work table in an inclined state,
That is, since the worker is fixed so as to be lower, the work of aligning the petiole portions of leaf tobacco can be performed with high efficiency.

In the lift device, since the cross-linking ramp is rotatably provided at the end of the rail, the leaf tobacco and the hanging rack holding the tobacco can be easily moved to the dryer side with respect to the dryer-side receiving rail facing the dryer. It became possible to transfer and take out. The effects described in (1) to (4) enable a reduction in the cost of the apparatus for drying the tobacco, a reduction in the operation of drying the tobacco, and an improvement in the work efficiency.
