Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a pallet for a forklift.

[Prior Art] A conventional forklift pallet is separate from the forklift arm (claw), and the forklift approaches the pallet and inserts the arm below the pallet to lift it.

The forklift pallet may have a plurality of rollable rollers for facilitating the loading and unloading of the conveyed product on the pallet and for adjusting the position on the pallet. This roller has the upper end rolling surface above the upper surface of the pallet frame, and when an object is placed, the object hits the roller,
Items can be moved on the pallet.

[Problems to be solved by the invention] However, in the case of a pallet with a roller, there is an advantage that the object placed on the pallet can be freely moved on the pallet to adjust the position and can be unloaded from the pallet. Since it moves freely on the pallet in one horizontal direction, if you want to securely fix the item to the pallet, for example, during transportation or when the forklift arm and pallet are tilted from the horizontal, the item moves and falls off the pallet. There is a problem in that the cargo may collapse or the cargo may collapse.

The present invention, in a forklift pallet with a roller, allows the roller to be retracted from the upper surface of the frame body of the forklift pallet, and when the object is to be moved on the pallet, the roller is projected, and when the object is fixedly fixed to the pallet. An object of the present invention is to allow the roller to be submerged below the upper surface of the frame.

[Means for Solving the Problems] As shown in FIG. 1, a forklift pallet according to the present invention for achieving the above object includes a first frame body 4 supported by a forklift arm 2 and a first frame body 4. Frame 4
A second frame body 6 movably supported in the vertical direction, a plurality of rollers 8 mounted on the second frame body 6, and the second frame body 6 attached to the second frame body 6 Leg body 12 that penetrates the first frame body 4 and projects downward from the lower surface of the first frame body 4 when descending relatively to the frame body 4, and the first and second frame bodies. And an elevating means 10 which is interposed between the fourth frame 5 and the fourth frame 6 and which drives the second frame 6 to rise relative to the first frame 4.

[Operation] When it is desired to move an object in the horizontal direction on the forklift pallet, the upper end of the roller 8 is projected above the upper end surface of the first frame body 4. In such a case, as shown in FIG. 1, when the forklift arm 2 is carried in and out on the pallet with the floor surface FL grounded,
As shown in the figure, there is a case where the forklift arm 2 is stationary at a position spaced upward from the floor surface, and at the same level, an object is horizontally loaded and unloaded from a shelf or the like onto a pallet. In the case of FIG. 1, the lower ends of the legs come into contact with the floor surface to lift the second frame 6 and the rollers 8 supported thereby, and the upper ends of the rollers are projected above the upper surface of the first frame 4. . In the case of FIG. 2, the elevating means 10 such as hydraulic means is actuated to actuate the second frame 6 and the rollers 8 supported thereby.
Is relatively lifted with respect to the first frame body 4, and the upper end of the roller is projected above the upper surface of the first frame body 4.

When it is desired to stabilize the object on the forklift pallet so that it cannot be moved horizontally, the forklift pallet is lifted from the floor surface, and as shown in FIG. Second frame body 6
And the roller 8 mounted thereto is lowered relative to the first frame body 4 so that the upper end of the roller is below the upper surface of the first frame body 4. Since the pallet is lifted from the floor surface in the relative lowering of the second frame body 6 with respect to the first frame body 4, the lower ends of the legs 12 do not interfere with the floor surface. The load is further stabilized on the pallet by pressing the load from above with a pusher if necessary. Furthermore, the load may be laterally supported by a backing plate if necessary. In such a case, even if the loaded object is tilted together with the forklift arm and the pallet, the load is not lost.

[Embodiment] An embodiment of the present invention will be described below.

In FIGS. 1 and 4, the first frame body 4 is attached to the forklift arm 2. It may be detachably attached. The first frame body 4 is a horizontal portion.
It has a protrusion 4b extending upward from it and the upper surfaces 4c of the protrusions 4b are on the same horizontal plane.

The second frame body 6 has the first frame body 4 between the projecting portions 4b.
It is supported so as to be vertically movable relative to the frame body 4. The second frame body 6 is equipped with a plurality of rollers 8 which are rotatable. The upper end of the roller 8 is located above the upper end surface of the second frame body 6. The roller 8 may be a free roller or a roller that is forcibly rotated by a motor. When the second frame body 6 is at the rising end position, the roller upper end is above the upper surface 4c of the first frame body 4, and when it is at the descending end position, the roller upper end is the first frame body 4
Is below the upper surface 4c.

A leg 12 extends downward from the second frame 6. The leg body 6 is inserted through the horizontal portion 4a of the first frame body 4 when the second frame body 6 is lowered relative to the first frame body 4, and the lower surface of the horizontal portion 4a is The forklift arm 2 extends below the lower surface of the forklift arm 2 by a length that allows it to project downward.

Between the first frame body 4 and the second frame body 6, an elevating means for raising the second frame body 6 relative to the first frame body 4.
Ten are provided. The elevating means 10 is composed of, for example, a hydraulic pressure increasing means, and when the hydraulic pressure is introduced, it raises the second frame body 6, and when the hydraulic pressure is removed, the second frame body 6 is inserted. Since the forklift has a hydraulic system, hydraulic pressure is guided from there.

In FIG. 1, reference numeral 14 is a pressing tool for pressing a load, for example, a printed material from above, and 16 is a side plate which is applied to the load from the side. These reliably prevent the forklift arm 2, the pallet, and the load from slipping when tilted. In FIG. 2, reference numeral 18 is a proximity switch for leveling the shelves 20 and the like with the pallet.

 Next, the operation will be described.

1 and 2 show a state in which the load can be moved horizontally on the pallet, and FIG. 3 shows a state in which the load is stably placed on the pallet without being horizontally movable. . The state of FIG. 1 is a state in which the forklift arm 2 is in contact with the floor surface FL, and FIG. 2 is the state of the forklift arm 2
Shows a state in which is separated upward from the floor surface FL.

In the state of FIG. 1, the lower end of the leg 12 interferes with the floor surface FL, or the elevating means 10 lifts the second frame 6 from the first frame 4 and the upper end of the roller is the first. The upper surface 4c of the protruding portion 4b of the frame body 4 is projected upward.

In the state of FIG. 2, the second frame 6 is moved up and down by the elevating means 10.
By being lifted from the first frame body 4, the upper end of the roller is projected above the upper surface 4c of the projecting portion 4b of the first frame body 4. This state appears when the load is transferred between the upper surface of the shelf above the floor surface FL and the pallet on the forklift arm.

In the state shown in FIGS. 1 and 2, since the roller 8 is projected, the load can be moved on the pallet by the rolling of the roller 8, and the load can be easily loaded into and unloaded from the pallet.

In the state shown in FIG. 3, the elevating means 10 is inactivated or driven downward, and the second frame body 6 is relatively lowered with respect to the first frame body 4. Frame 4 of 1
When the upper surface 4c of the protruding portion 4b of the
Supported above. Therefore, the load does not easily move in the horizontal direction due to the frictional force between the load and the upper surface 4c of the first frame body 4. Thereby, the collapse of the load during the transportation is prevented. When the load 14 is pressed against the first frame 4 from above by the pusher 14 or is laterally supported by the side support plate 16, the load is further stabilized.

[Advantage of the Invention] According to the present invention, the second frame is provided on the first frame so as to be movable up and down, and the legs or the first and second frames attached to the second frame are provided.
By the elevating means interposed between the frame bodies, the roller mounted on the second frame body can be made to protrude upward from the upper surface of the first frame body or be made to be depressed below. By this, when you want to move the load on the pallet on the contrary, you can project the roller so that the load can be moved horizontally on the pallet, and conversely if you want to stabilize the load on the pallet. It is possible to stabilize the load by immersing the roller below the upper surface of the first frame and fixing the load on the pallet so that the load cannot move horizontally.
