Description

[Detailed Description of the Invention] This proposal relates to a panel clamp device for handling panel materials used in prefabricated houses and the like.

In recent years, with the spread of prefabricated houses using the two-by-four (2 x 4) construction method, the work of handling panel materials used in prefabricated houses has increased dramatically.

Conventionally, this work was carried out in advance by transporting a large number of panel materials stacked at intervals using railroad ties, and then using a forklift truck to take out the panel materials one or more at a time and transport them to the location where the panels would be used. It was being transported.

For this reason, railroad ties are required to transport the panel materials, which makes loading and unloading work troublesome.In addition, the stacking height of the panel materials increases by the number of railroad ties, so in locations with height restrictions, the number of panels that can be transported at one time is limited. There is a limit to

In addition, when loading and unloading panel materials, the panel materials are easily damaged by forks, and when panel materials are transported as units for each purpose, it takes time to distribute the units.
There were drawbacks such as poor work efficiency.

This proposal was made to eliminate this drawback, and aims to improve work efficiency by providing a panel clamp device that can handle multiple panels without using sleepers. It is.

This filial plan will be described in detail below with reference to an illustrated embodiment.

In the figure, 1 is the main body of this device, which consists of a front frame 2 and a rear frame 3.

The front frame 2 has an almost inverted L shape, and the horizontal part 2
The distal end side of a is branched into two paths, and a clamp cylinder 4 is located between the branch paths, and one end of the clamp cylinder 4 is pivotally attached to a part of the horizontal portion 2a.

Further, a plurality of rollers 5 are rotatably supported on both sides of the horizontal portion 2a, spaced apart from each other in the front and rear.
are fitted into the horizontal portions 3a of the rear frame 3 provided on both sides of the horizontal portion 2a, and the front frame 2
It guides the forward and backward movement of the

The rear frame 3 also has a substantially inverted L shape, and the two horizontal portions 3a project from the upper end of the vertical portion 3b.

Between the tips of these horizontal parts 3a is the horizontal part 2 of the front frame 2.
They are connected to each other by a horizontal rod 6 on the upper side of a, and the other end of the clamp cylinder 4 is pivotally attached to the upper end of the vertical part 3b of the rear frame 3, and by expanding and contracting the clamp cylinder 4, the front The frame 2 can be moved back and forth.

On the other hand, on the rear surface of the vertical portion 3b of the rear frame 3, hooks 7 are vertically spaced apart and protrude, and the hooks 7 are engaged with a finger board 10 that is vertically movable along a mast 9 of a forklift truck 8. As a result, the main body 1 can be mounted on the forklift truck 8, and strip-shaped clamp pads lla made of an elastic material such as rubber are arranged in multiple rows in the vertical direction on the front surface of the vertical portion 3b of the rear frame 3. It is installed across.

Further, on the rear surface of the vertical part 2b of the front frame 2 facing these clamp pads lla, a plurality of button pads lla are provided.
b are arranged in parallel.

These bushing pads llb are arranged at intervals in the vertical direction so that two of each are in contact with the end faces of the panel materials 12 which are stacked and positioned between the respective vertical parts 2b and 3b of the front and rear frames 2 and 3, and are guided. A mounting with rods 13 is attached to the front side of plate 14.

The guide rod 13 is horizontally and slidably supported by a guide boss 15 provided on the vertical frame 2b, is biased in the retracting direction by a compression spring 16, and has a roller 17 supported at its tip. , these rollers 17 are in contact with the cam surface 18a of the pressure release plate 18.

The pressure release plate 18 is provided in the vertical part 2b of the front frame 2, and is movable up and down by a button cylinder 19, and has an inclined cam surface 18b formed on the lower end side. The cam surface 18b allows each of the bushing pads 11b to retreat.

Therefore, when loading and unloading the panel materials 12, the panel materials 12 are piled up at an appropriate height on the road surface, etc.
The main body 1 is lowered from above the panel material 12 so that it is located between the vertical parts 2b and 3b of the front and rear frames 2 and 3.

Next, the inclined cam surface 18b of the pressure release plate 18 is positioned at the lowest position, and the clamp cylinder 4 is shortened with each button pad llb protruding, and each panel member 12 is placed between the button pad llb and the clamp pad lla. clamp and lift it to an appropriate height as shown in Figure 2.

In this state, the forklift truck 8 is driven to move the panel material 12, and when it reaches the location where the lowest panel material 12 is used, the button chassis ring 19 presses the release plate 1.
Raise 8 by 1 pitch.

Note that this pitch is set approximately equal to the thickness of one panel material 12.

As a result, the roller 17, which has been pressed by the cam surface 18a of the pressure release plate 18, moves along the inclined cam surface 18b, and the compression spring 16 causes the guide rod 13 to retreat as shown in FIG. Therefore, the lowermost panel material 12, which has been held between the bushing pad llb and the clamp pad lla, is released and falls.

By repeating the above operations one after another, it becomes possible to transport one or more panel members 12 to a predetermined location.

The lamp pad lla may have a structure in which it is biased in the projecting direction by a compression spring 20, as shown in FIG.

As detailed above, this draft plan involves clamping multiple panels at once, which are stacked without using sleepers, and then releasing one or more panels from the bottom at a predetermined location. This eliminates the need for sleepers during cargo handling, making the work easier and reducing height restrictions, improving transportation and storage efficiency.

Furthermore, since a plurality of panel materials can be transported for each unit, the work of distributing the units can be done efficiently and in a short time.
