Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to a cargo handling device attached to a truck, and is suitable for loading and unloading block-shaped raw rubber.

<Prior art> Raw rubber is imported into Japan in the form of blocks measuring 60 cm on a side, and marine containers are used for transportation.

Traditionally, a forklift was used to unload this rubber block from the sea container. However, the rubber blocks were packed in bulk in the container and could not be loaded and unloaded properly by the forklift.

<< Problems to be Solved by the Invention >> The present invention aims to obtain a machine suitable for loading and unloading such raw rubber blocks.

<< Means for Solving the Problem >> The load holding device of the present invention comprises an elevating member that moves up and down in the front part of the carriage, and a holding part attached to the elevating member. The holding part is composed of upper and lower jaws that are opened substantially at right angles, and upper and lower jaws that respectively project and retract from these upper and lower jaws.

When using, the carriage is advanced and the lifting member is lowered to press the upper and lower jaws against the luggage. Then, pull out the nails from the chin to grab the luggage and carry it.

In order to increase the outreach, the arm can be extended forward from the elevating member and the gripping part can be attached to the end thereof.

Two gripping parts can be installed side by side so that two pieces of luggage can be grabbed at the same time. In this case, it is preferable that the holding portion is movable back and forth with respect to the carriage and is biased forward by a spring. In this way, even if one of the two side-by-side loads is in the front and the other is retracted in the back, each holding portion can be pressed exactly against the corresponding load, and therefore, the two loads can be pressed. Can be reliably grasped.

Further, in order to securely grip the luggage, the holding portion may be attached so as to be rotatable back and forth.

There are various possible structures for retracting the claws, but the upper and lower claws extend at right angles to the ends of the upper and lower rods pivotally supported by the upper and lower jaws respectively, and by rotating the upper and lower rods with a hydraulic cylinder, It is easy if the upper and lower claws are configured to project from the upper and lower jaws.

«Embodiment» In FIG. 1, reference numeral 1 is a dolly, and a column 2 stands on the front of the dolly, and an elevating member 3 is supported so as to be vertically movable along the column 2. Sprockets 4 and 5 are provided above and below the column 2, and a chain 6 is suspended on the sprockets. The elevating member 3 is connected to this chain. Therefore, when the hydraulic motor 7 rotationally drives the sprocket 4, the elevating member 3 moves up or down.

An arm 8 extends forward from the elevating member 3, and a horizontal axis 9 intersects and is fixed to the tip of the arm 8. Clamping portions 10 are attached to the left and right of this shaft, respectively. The clamp comprises upper and lower jaws 16 which are open at right angles.

The holding section 10 will be further described with reference to FIGS. 2 to 4. A vertical axis 11 is fixed to the upper part of the holding tool 10 in the front-rear direction. A slide bearing 12 is engaged with the vertical axis 11, and the slide bearing is connected to a journal bearing 13 supporting the end of the horizontal shaft 9. Therefore, the holding part 10 can rotate around the horizontal shaft 9 (FIG. 1) and can move back and forth with respect to the horizontal shaft 9 (second position).
Figure).

Reference numeral 14 is a tension spring for urging the holding portion 10 forward with respect to the horizontal axis 9. Because of the spring 14, the gripping tool 10 is normally at the position shown in the drawing, and when the gripping tool 10 hits the load 15, the gripping tool 10 retreats like a chain line.

A pin 17a is fixed to the upper surface of the upper jaw 16a, and a rod 18a is rotatably supported by the pin 17a. A claw 19a extends downward from the tip of this rod. Similarly, a rod 18b is rotatably supported by a pin 17b fixed to the rear surface of the lower jaw 16b, and a claw 19b extends forward from the tip of this rod. A hydraulic cylinder 21 is placed between a pin 20a and a pin 20b which are respectively fixed to these rods 18a and 18b, and when the hydraulic cylinder is extended, the upper and lower claws 19a and 19b project inside the jaw 16 and the raw rubber When pierced by the block 15 and the cylinder is contracted, both claws are pulled in (Fig. 3).

When using, the carriage 1 is moved forward and the arm 8 is lowered to press the gripping tool 10 against the rubber block 15 (FIG. 1).

At this time, when the two blocks are not arranged in order and one is in the foreground and the other is retracted in the back, when the trolley 1 is advanced, one of the holding tools 10 hits the protruding block. Contact. When the trolley 1 is further advanced, the spring extends and the sandwiching tool does not move forward, but only the sandwiching tool on the opposite side advances and eventually comes into contact with the block that has been retracted.

Then, the hydraulic cylinder 21 is extended, and the upper and lower claws 19 are moved to the jaw 16
And stick the tip of the nail into the raw rubber block 15. In this way, if the arm 8 is raised, the block 15 can be raised, and the trolley | bogie 1 is run and it carries to a desired position.

<< Effect of Invention >> According to this invention, there are the following effects.

The gripping device according to claim 1 comprises an elevating member that moves up and down in the front part of the carriage, and a gripping part attached to the elevating member. The gripping part includes upper and lower jaws opened at a substantially right angle, and these upper and lower jaws. It consists of upper and lower claws that appear and disappear, and it is possible to take out the luggage stacked in front, back, left and right without any gap by sequentially grasping the luggage from the uppermost row of the front row with the holding section.

In the apparatus according to the second aspect, since the holding portion is attached to the tip of the arm that extends forward from the elevating member, it is possible to load and unload a load apart from the truck.

In the device according to the third aspect of the present invention, since the two sandwiching portions are arranged side by side and attached, two loads can be unloaded at the same time.

According to claim 4, each of the two holding portions is movable back and forth with respect to the carriage, and is urged forward by a spring, so that one of the two side-by-side loads comes out to the front, Even when the other is retracted in the back, the holding portions can be pressed exactly against the corresponding luggage and can be reliably gripped.

In the device according to the fifth aspect of the present invention, the sandwiching portion is rotatably attached to the front and rear. Therefore, when the sandwiching portion is pressed against the luggage, the sandwiching portion rotates according to the posture of the luggage and closely contacts the luggage. Therefore, the luggage can be reliably grasped.

According to the device of the sixth aspect, a simple structure in which the claws appear and disappear from the upper and lower jaws can be obtained.
