Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention is applicable to cargo handling and transportation work.
The present invention relates to a jig for loading and unloading articles, which makes it possible to unload goods to a predetermined position without touching the goods during unloading.

0002

[Prior Art] Conventionally, in cargo handling operations such as transportation, unloading, and loading, transport vehicles such as forklifts are used for heavy objects, and trolleys and the like are used for relatively light objects. ing. However, with these methods, cargo is moved using transport vehicles or trolleys, but unloading and loading are carried out by workers who directly touch the cargo. For these operations, devices have been considered that use movable conveyors to unload or load cargo into predetermined positions, and one example of this is the technique disclosed in Japanese Patent Publication No. 15591/1983. That is, in this technique, when the movable conveyor device is moved from the loading position to the original position, the conveyor belt of the movable conveyor device is moved in a direction opposite to the moving direction of the conveyor device and at a speed of this movement. This is a device that loads cargo into a predetermined position by rotating in synchronization with the

0003

[Problems to be Solved by the Invention] Such a movable conveyor device requires a strong frame and large-scale equipment, and requires a power source, wiring, piping, etc. to drive them, so it is difficult to load. , it is not suitable for applications where the unloading position changes frequently. An object of the present invention is to provide a very simple transport and unloading jig that can be loaded or unloaded to a predetermined position when loading or unloading cargo.

0004

[Means for Solving the Problems] In order to achieve the above object, the present invention has carried out extensive research and has developed a loading/unloading jig having the following configuration. That is, the gist of the present invention is a jig that is inserted under a loaded article and used for loading and unloading, in which a plurality of rotating bodies are arranged in two stages, upper and lower, and the rotating bodies in the upper and lower stages are arranged. The lower parts of the rotating bodies in the lower stage are on the same horizontal plane and in contact with the floor surface, while the upper parts of the rotating bodies in the upper stage are on the same horizontal plane or part of it is on an inclined plane and touch the bottom surface of the loaded object. A jig for loading and unloading articles, characterized in that it is equipped with rotating mechanisms arranged so as to touch each other,
The rotating body is, for example, a roller, a wheel, a ball, or a mutually meshing gear, and is preferably provided with a pulling mechanism for pulling out the loaded object from below, and in particular, the rotation direction of the rotating body,
This is a loading/unloading jig that matches the pulling direction. As a modification thereof, a jig for loading and unloading articles may be considered, which has a separation function in which rotating bodies arranged in two stages, upper and lower, can simultaneously come into contact with or separate from each other.

The present invention is an article loading/unloading jig that adopts the above-mentioned configuration, in which articles are loaded onto this jig by known means, and after being transported to a predetermined location, the jig is loaded and unloaded. By pulling it out from under the loaded object, it is possible to unload the cargo without changing its position. Known means for loading articles onto the jig include a transport vehicle such as a forklift, a crane, manual labor, and the like. Further, there are no restrictions on the means for transporting the jig together with the jig while it is loaded on the jig, such as transport using a forklift or the like, transport using a trolley, etc. Furthermore, it goes without saying that the jig having the mechanism of the present invention may be incorporated into the transport vehicle itself.

[0006]

[Operation] To further characterize the jig of the present invention, rotating bodies such as rollers that are arranged in a staggered manner and in contact with each other, when one rotating body is rotated, the other rotating bodies that are in contact with each other are Although it has the property of rotating in opposite directions, the present invention takes advantage of this feature and takes advantage of the fact that there is no change in the relative positional relationship between the loaded item and the floor from which it is to be unloaded.

FIG. 1 is a diagram showing the principle of a jig having a mechanism according to the present invention, in which numeral 1 shows a floor, 2 an object to be loaded, and 3 the basic structure of the jig according to the present invention. In this jig 3, rollers 4 as a rotating mechanism are arranged in two stages (A, B), upper and lower, and the roller 41 in the upper stage A is connected to the roller 42 in the lower stage B.
is in contact with. As shown in the figure, the upper part of the roller 41 in the upper stage A is in contact with the lower surface of the loaded object 2, while the lower part of the roller 42 in the lower stage B is in the same horizontal plane and on the floor 1. are in contact. The loaded object 2 is a jig 3
The jig 3 is carried on a predetermined floor 1 to be unloaded, and the jig 3 is pulled out in the direction of arrow Z here. However, in the case of the roller 42 in the lower stage B,
Rotates counterclockwise due to this pulling force (arrow X)
However, on the other hand, the roller 41 that is in contact with this roller 42 will rotate clockwise (arrow Y).

Therefore, in this jig 3, the circumferential length of the roller 42 on the lower stage B that moves in the Z direction in contact with the floor 1, and the roller 41 on the upper stage A that rotates in contact with the loaded object 2. The circumferential speed and circumferential length will be the same as long as there is no slip. In other words, this means that there is no change in the positional relationship between the floor 1 and the loaded object 2 before the jig 3 is pulled out. Just by pulling it out, the loaded object 2 will be naturally loaded at a predetermined position on the floor 1.
