2. Description of the Related Art As shown in FIGS. 12 and 13, in a glass plate storage warehouse, a large number of large glass plates (G) are placed in a predetermined number by a well-known glass plate storage device (101) called a placing horse or the like. It is customary to store each lot separately.

This glass plate storage device (101) comprises a glass plate stand frame (102) having an isosceles triangular shape in side view,
A glass plate support (103) provided so as to project in the front-rear direction is provided at the lower end of the stand frame (102), and a large glass plate (G) is provided for each lot, and the lower end thereof is used as the support (103). In addition to being supported, one side is stored so as to lean against the hanging frame (102).

By the way, in recent years, in order to facilitate the work of loading and unloading glass plates (G), a large glass plate loading / unloading holder (110) has been installed in such a glass plate storage device (101). Being developed.

[0005] A conventional large glass plate cargo handling holder (11
0) is a holder main body (111) arranged along one side of the glass plate (G), and a lower claw (112) for supporting the glass plate provided on the lower end of the main body (111) so as to project forward.
And a locking piece (113) for locking the glass plate provided on the upper end of the main body (111).

When the glass plate (G) stored in the storage device (101) is taken out by the cargo handling holder (110), for example, the holder (110) is hung by the upper end center thereof. The crane hook is engaged with and suspended from the engaging portion (114) for the holder, and the holder (110) is conveyed to a position corresponding to a predetermined glass plate (G), and then the holder (110) is attached to the glass plate. Lower along the outer surface of (G). During this descent, the lower claw (1
An operator in the vicinity of the holder assists the holder (110) so that the holder (110) is not abutted and locked by the glass surface of the glass plate (G) to prevent the descending movement of the holder (110). Therefore, it is necessary to hold the holder (110) in a posture inclining forward.

In this way, the holder (110) is lowered, and the hooking piece (113) is hooked on the upper edge of the glass plate (G). Then, the operator attaches the lower end of the holder (110) to the glass. The lower claw (112) is moved to the plate (G) side and inserted below the lower edge of the glass plate (G).

After that, when the holder (110) is lifted by a crane, the upper edge of the glass plate (G) is hooked (11).
The lower end is supported by the lower claw (112) while being retained by 3), and the glass plate (G) is retained by the retainer (110).
In this holding state, the holder (110) is lifted upward. In this way, the work of taking out the glass plate (G) is performed.

On the other hand, in order to transfer the glass plate (G) held by the holder (110) to the storage device (101), basically the reverse procedure to the above is carried out. That is, the holding device (110) is moved by the crane to the storage device (101).

In addition, every time the cargo handling work is performed, the worker needs to insert or remove the lower claw (112) of the holder (110) toward the lower edge of the glass plate. Was made more complicated.

On the other hand, in recent years, in a glass plate storage warehouse or the like, in order to effectively utilize the space, the above-mentioned storage devices (101) are densely arranged side by side,
Alternatively, there is an increasing tendency to employ a storage device in which a large number of standing frames are arranged side by side. For this reason, a sufficient working space cannot be secured on the outer surface side of the glass plate (G), and it is difficult to secure a place for a person who performs auxiliary work for lifting and lowering the holder and insertion / removal work of the lower claw (112). In some cases, the conventional holder (110) may not be able to handle the glass plates.

The present invention solves the above-mentioned problems of the prior art, and when a plate-like object such as a large glass plate is transferred to a storage device or the like, the lower claw can be automatically pulled out from the lower edge side of the plate-like object. The purpose is to provide a cargo handling holder such as a large glass plate that can easily and reliably carry out cargo handling work even if the work space is small.

Further, as shown in FIG. 1 and the like, the holder (1) of this embodiment includes front faces of the aggregates (21) to (24), an upper face of the lower claw (3), and a hooking piece (5). A cushioning member (11) made of rubber or the like is provided in a portion such as a portion contacting the glass plate (G). Further, an inverted U-shaped suspending metal fitting (25) is fixed to the center of the upper edge of the holder body (2), and the vertical aggregates (21) (21) and the lower transverse aggregates on both sides are fixed. Handle members (26), (26) and (27) are detachably attached to (23).

Next, a description will be given of a case where the glass plate (G) stored in the glass plate storage device (9) by the glass plate cargo handling holder (1) having the above-mentioned structure is taken out for each lot. The glass plate storage device (9) used in the present embodiment is such that a large number of glass plate standing frames (91) having an isosceles triangular shape in side view are arranged side by side on a support base (92). And a glass plate (G) for each small lot
However, in the state of being supported by the support table (92), it is leaned against each standing frame (91) and stored.

First, the contact roller (8) of the lower claw disengaging mechanism (6) of the cargo handling holder (1) is retracted and set to the roller retracted position as shown in FIGS. 6 and 9 (a). deep. In this state, as shown in FIG. 3 (a), the crane hook is engaged with and suspended by the hanging engagement metal fitting (25) of the cargo handling holder (1), and the holder (1) is predetermined. The glass plate (G) is conveyed to a position corresponding to the upper side, and the holder (1)
Is lowered along the outer surface of the glass plate (G). At this time, the guide roller (4) at the tip of the lower claw rolls along the outer surface of the glass plate (G), so that the holder (1) moves along the glass plate (G) without the assistance of the operator. And descend while being guided accurately.

By lowering the holder (1) in this manner, the hooking piece (5) is hooked on the upper end of the glass plate (G) as shown in FIG. When 3) crosses the lower edge of the glass plate (G), the holder (1) rotates a small amount counterclockwise in the figure with the upper end as a fulcrum due to its own weight.
The lower claw (3) is automatically inserted below the lower edge of the glass plate (G).

After that, when the holder (1) is lifted by a crane, the lower edge of the glass plate is supported by the lower claw (3) while the upper edge of the glass plate (G) is retained by the retaining piece (5). Then, the glass plate (G) is held, and the holder (1) is lifted in the holding state. In this way, the work of taking out the glass plate (G) is performed.

On the other hand, when one lot of glass plate (G) held by the holder (1) is transferred to the storage device (9), it is first shown by an imaginary line in FIG. 9 (a). As described above, the contact roller (8) of the lower claw disengagement mechanism (6) is pushed out toward the glass plate (G) side, and the contact roller (8) is biased in the projecting direction by the biasing force of the tension spring (68). And press it against the plate surface of the glass plate (G). In this state, since the glass plate (G) is pressed against the lower claw (3) by its own weight with a larger frictional force, the forward movement of the glass plate (G) is prevented even if it is pushed by the contact roller (8). It goes without saying that removal is also prevented.

In this state, as shown in FIG. 4 (a), the holder (1) is conveyed to a position above the storage device (9) and lowered. This lowering causes the lower edge of the glass plate to come into contact with the support base (92) of the storage device (9) as shown in FIG. 4 (b), and thereafter, the load of the glass plate (G) gradually increases from the lower claw (3). The glass plate (G) is leaned against the leaning frame (91) while moving to the support base (92). Then, as shown in FIG. 5 (a), the frictional force between the lower claw (3) and the glass plate (G) is reduced by the shift of the glass plate load, and is smaller than the biasing force of the tension spring (68). Then, the contact roller (8) pushes the glass plate (G) relatively forward, whereby the holder (1) rotates a small amount in the clockwise direction in the figure with the upper edge as a fulcrum, and the lower claw (3 ) Automatically comes out from the lower edge of the glass plate.

Thus, the glass plate (G) is stored in the storage device (9).
Then, the holder (1) is lifted by a crane as shown in FIG. 5 (b). At this time, the contact roller (8) and the guide roller (4) at the tip of the lower claw, which are held in the protruding state, roll on the outer surface of the glass plate (G), so that they can be held without the assistance of the operator. The tool (1) rises while being accurately guided along the glass plate (G).

As described above, according to the glass plate cargo handling holder (1) of this embodiment, when the holder (1) is lowered along the glass plate (G), the guide roller (4) is used. By rolling on the plate surface of the glass plate (G), the holder (1) can be accurately moved along the glass plate (G) without the assistance of the operator, and the lower claw ( 3) can be automatically inserted into the lower edge of the glass plate. Also,
When the glass plate (G) is transferred from the holder (1) to the storage device (9) and the lower edge of the glass plate is mounted on the support base (92) of the storage device (9), the contact roller (8) ), The lower claw (3) automatically comes out from the lower edge side of the glass plate. Moreover, when the glass plate (G) is transferred to the storage device (9) and then raised, the guide roller (4) and the contact roller (8) roll on the plate surface of the glass plate (G). By doing so, the holder (1) can be moved accurately along the glass plate (G) without the assistance of the operator.

In this way, the holder (1) can be moved up and down without the assistance of the operator, and the lower claw (3) can be automatically inserted and removed, so that the manual work is reduced.
Even if the work space is small, the glass plate loading and unloading work can be performed easily and reliably.

The holder of the present invention is not limited to loading glass plates, but can also be used for loading other plate-shaped objects such as synthetic resin plates.

[0045]

As described above, according to the cargo handling holder of the present invention, such as a large glass plate, the contact member such as a contact roller attached to the holder main body so as to be able to move back and forth, and the contact member. There is provided a lower claw disengagement mechanism including an urging means such as a spring for urging the lever in the protruding direction and a position holding means for holding the contact member in the retracted position. Therefore, for example, when a plate-like object such as a large glass plate held by a holder is transferred to a storage device or the like, the plate surface of the plate-like object is biased by the biasing means in the protruding direction. When the holder is lowered and the plate-like object is placed on the support stand of the storage device, the contact member pushes the plate-like object relatively forward, and the lower claw is plate-like. It automatically escapes from the lower edge of the object. In this way, since the lower claw extraction operation can be automatically performed without manual labor, there is an effect that a cargo handling operation such as transfer of a plate-shaped object can be easily and reliably performed even if the work space is small.

In the present invention, the following advantages are obtained when the guide roller is attached to the tip of the lower claw. For example, in the case of taking out a plate-like object stored in a storage device, the guide roller rolls on the plate surface when the holder is lowered along the plate surface, without the assistance of the operator,
The holder can be accurately lowered along the plate surface, and the lower claw can be automatically inserted into the lower edge side of the plate-like object after the lowering. On the other hand, even when the holder is moved up along the plate surface after the plate-shaped object is transferred to the storage device, the guide roller and the contact roller roll on the plate surface, so that there is no assistance from the operator. Moreover, the holder can be accurately raised along the plate surface. In this way, the holder can be moved up and down without the assistance of the operator, and the lower claw can be inserted automatically without any manual labor, so even if the work space is small, it is even easier to carry out plate-like material loading and unloading work. And there is an advantage that it can be done reliably.
