[0002]

2. Description of the Related Art Gypsum board is often used as an interior material (wall / ceiling) for buildings. The standard size of gypsum board is
Most of them are 3'x 6'or 3'x 8 ', and metric version 1 m x 2 m may also be used.
In the case of plasterboard upholstery on site, the standard size is brought to the site as a blank.

The loading platform of a gypsum board carry-in truck is generally a large pile of 120 m pieces having a thickness of 12.5 mm or 160 pieces having a thickness of 9.5 mm and a height of about 1.5 m. The gypsum board is loaded in, and the unloading from the bed of this truck is performed by any of the following methods. (1) Use a truck crane or unic to unload a large mountain and carry it to the desired floor cargo receiving area. (2) If there is a forklift at the site, lower it with that. (3) Build a mountain by manually dropping two to several sheets.

In addition, there are cases where it is desired to use a dolly or the like for horizontal transportation of the gypsum board to the place of use. However, a commonly used dolly is about 500 kg at most and a thickness of 12.5 mm and a size of 3 '× 6' gypsum. Height of 30 stacked on board 4
Even if you put something that is less than 0 cm, you can load it on the dolly by using the method of (1) or (2) above even if you unload it from the truck by the method of (3) above. It requires unloading work to create mountains while unloading
Similarly, when unloading from the dolly, it is necessary to perform unloading work to create a mountain while manually unloading two to several sheets.

In such a conventional method, human power is forced to be used for unloading and transshipping gypsum board, which requires heavy work, and depending on the heights of the gypsum board to be collapsed and piled up, a middle waist posture In addition, depending on the horizontal movement distance and the condition of the floor and aisle maintenance, even if there is a dolly, it is not very useful, and even if you use the dolly once, it will take time for loading and unloading. The unloading work of making a mountain while manually unloading two to several sheets is necessary twice. For this reason, if you carry a few plasterboards at a time when unloading, it will be easier and faster to carry it to the intended place as it is, and the job category of "loader" was born. come. When a crane is used for unloading and transshipping gypsum board, even if nylon slings are used, cracks and scratches will occur in the bottom gypsum board of the suspended load, making the bottom gypsum board useless.

In order to eliminate such inconvenience, (1)
Boards can be lifted together, (2) boards can be divided into mountains, and small mountains can be taken even if there is no pier from large mountains, (3) the height of the small mountains to be taken in can be adjusted, (4) boards (5) It is equipped with a safety mechanism for lifting without damaging the
When unloading at the intended place, it can be unloaded without a shackle. (7) A lightweight device was required.
In response to such a demand, conventionally, a plate-shaped material separating device shown in FIGS. 18 to 24 has been proposed.

When using 3 ', first, hang it on a hoist or crane that moves on the rail and move it onto the load of the plate-like material 58 at the transshipment place, and the arm 20 moves above the load of the plate-like material 58. When the space between the left and right arms 20 is opened and the plate material separating device 33 'is lowered as it is, the left and right material hoisting hands 72 are inclined while descending while rubbing the side surface of the plate material 58. (FIG. 20).

The plate-shaped materials 58 are stacked on the pier 60, and when the plate-shaped material separating device 33 'descends until the material hoisting hand 72 reaches below the pier 60, the material hoisting hand 72 and the lowermost stage. The plate-like material 58b of FIG. 21 falls into the gap 59 between the plate-like material 58b and the floor surface 71, and the plate-like material 58 stacked on the pier 60 is supported by the material lifting hand 72 and can be lifted (FIG. 21).

Next, when the plate-shaped material separating device 33 'is hoisted in this state, the load of the load acts so as to separate the base elevating frame 24 and the horizontal fixed frame 25, and the projecting swing rod 16 is directed upward. Since the rotation moment acts and the movable connecting rod 13 moves to the boundary line 15 side (inside), the arm 20 is brought into close contact with the side surface of the plate-like material 58,
It is supported from below by the material hoisting hand 72, and receives the lateral pressure from the left and right arms 20 to hoist the plate material 58 (FIG. 22).

In this way, the plate-like material 58 is hoisted and moved to the loading / unloading place, and is hung down on the pier 60 placed on the floor surface 71, and the plate-like material 58b at the bottom is placed on the pier 60. When the load reaches, the load load does not act on the base elevating frame 24 and the horizontal fixed frame 25, so that the movable connecting rod 13 can move to the outside of the boundary line 15.
The material hoisting hand 72 is pushed up, and the work is finished by unloading from the lowermost plate-shaped material 58b to the outside (FIGS. 23 and 2).

As described above, in the plate-shaped material separating device 33 'according to the prior art, the inside of the arm 20 is parallel to the boundary line 15, so that when the side surface of the load has irregularities. Is the lowermost plate-like material 5 when it is lifted
It is difficult for the lateral pressure from the arm 20 to act on the side surface of the armature 8b, and therefore the load cannot be lifted only by the lateral pressure of the arm 20, and the material of the lower end 21 of the arm 20 that supports the lowermost plate-shaped material 58b to be picked up The lifting hand 72 is essential.

In the material hoisting hand 72, if there is no gap 59 below the lowermost plate-shaped material 58b, the lowermost plate-shaped material 58 cannot be picked up or unloaded. At the time of replacement, there is a gap 5 below the lowermost plate-like material 58.
The pier 60 provided with 9 is essential.

Further, below the lowermost plate-like material 58,
A gap 59 having a height corresponding to the length of the material hoisting hand 72 is required so that the material hoisting hand 72 can rotate from a horizontal state to a vertical state.
Must have a sufficient length so that the plate-like material 58 does not come off from it, so that the pier 60 laid under the load must also be sufficiently high.

However, if the height of the pier 60 is increased as described above, the load supported by the pier 60 becomes unstable and there is a risk of collapse of the load. Will have to be shortened.

Therefore, when the material hoisting hand 72 is shortened, the plate-like material 58 supported by the material hoisting hand 7 is held.
There is a danger that it will fall off 2 and fall off.

Since the horizontal fixed frame 25 is formed by connecting with each other,
When the plate-like material 58 is put between 0 and lifted, the load of the horizontal fixed frame 25 acts so as to separate between the base elevating frame 24 and the horizontal fixed frame 25, and the upward swinging moment is applied to the protruding swing rod 16. As a result, the movable connecting rod 13 moves to the boundary line 15 side (inner side), so that the arm 20 comes into close contact with the side surface of the plate-like material 58 and the left and right arms 2
The plate-shaped material 58 is gripped by receiving the lateral pressure from 0, and the load of the plate-shaped material 58 is further increased.
Since the plate-like material 58 receives a stronger lateral pressure from the left and right arms 20, it can be lifted up because the plate-like material 58 is separated from the horizontal fixed frame 25.

In that case, the left and right moving connecting rods 13A, 13
The lower end 21A of the arm 20A and the lower end 21 of the arm 20B, which face each other symmetrically with respect to the boundary line B from B, respectively.
Since B projects downward with an inclination that is inward, the lateral pressure from the arm 20 concentrates on the side surface of the plate-like material 58b in the lowermost stage. Therefore, it is necessary to attach to the lower end 21 of the arm 20 a material hoisting hand 72 that supports the plate-shaped material 58 from below, which was indispensable for lifting the plate-shaped material 58 in the plate-shaped material separating device 33 according to the related art.

It is shorter than the length N between the point and the point, and the length M between the left and right suspension rods 12 of the movable connecting rod 13 is also a straight line connecting the pin connecting points. Since it is longer than the distance H to the lower end 21 of 20, the horizontal fixed frame 25
The arm 20 strongly acts on the side surface of the plate-like material 58 by the rotation moment acting on the protruding swing rod 16 by the load of the plate-like material 58, and the plate-like material 58 is gripped by receiving a strong lateral pressure from the left and right arms 20. Will be hoisted.

An inner guide 30 projects from the horizontal fixed frame 25 toward the base elevating frame 24, and pin holes 31 a formed in the outer rail 29 and the inner guide 30.
Since the base elevating frame 24 and the horizontal fixed frame 25 are detachably connected to each other by the pin 32 which is inserted into and removed from the base elevating frame 24, the pin 32 can be inserted into the pin holes a and 31b. The distance P between the horizontal fixed frame 25 and the horizontal fixed frame 25 is fixed, and as a result, the arms 20A and 20B are set apart from each other,
The plate-shaped material separating device 33 can be hung so that the plate-shaped material 58 fits between the arms 20A and 20B.

If the pin 32 is removed in the suspended state, the space between the base elevating frame 24 and the horizontal fixed frame 25 becomes free, and the load of the horizontal fixed frame 25 causes an upward rotational moment to the protruding swing rod 16. The movable connecting rod 13 moves to the boundary line 15 side, the arm 20 comes into close contact with the side surface of the plate-like material 58, and the left and right arms 20 operate.
Since the plate-like material 58 is gripped and set by receiving the lateral pressure from, it becomes easy to set the plate-like material separating device 33 on the load.

The vertical bolts 34a, 34 for adjusting the product amount are provided in parallel with the boundary line 15 downward of the horizontal fixed frame 25.

Since the volume adjustment pressing board 36 is attached to the lower ends of 34c and 34d, the upper surface of the lifted plate-like material 58 is suppressed by the volume adjustment pressing board 36, as a result, the load is stabilized, and the plate-shaped material is divided into piles. Device 3
It is possible to prevent the plate-like material 58 from slipping from between the arms 20 in the process of moving 3.

The product quantity adjusting vertical bolts 34a, 34b,
