Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveying device for horizontally moving an object using vibration as a driving source.

0002

[Prior Art] Conventionally, there have been a wide variety of devices for transporting objects. In particular, horizontal self-propelled moving devices have wheels or roller-like devices (hereinafter referred to as ,
Abbreviated as "wheels, etc." ). The common method was to rotate such wheels using a motor, engine, etc. to move the object.

0003

[Problems to be Solved by the Invention] However, this conventional method requires a certain amount of space under the loading platform for arranging wheels, etc. and a drive device, and it is desirable to reduce this space and create a so-called low-floor type. There were limits to how much transport equipment could be made. Moreover, even the minimum drive mechanism involves various mechanical parts, and therefore some kind of maintenance is naturally required. The large number of cooperating parts increases the failure rate, which is a problem that affects the reliability of the device.

0004

[Purpose of the Invention] Therefore, as a result of focusing on and considering these problems, the present inventor has developed a simple structure that uses vibration as a driving source, which was not present in conventional means of transportation, and has a small number of component parts. The present invention provides a transportation device with improved reliability.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the transportation device of the present invention has a structure including a base to which a vibration generating means is coupled, and an elastic and a plurality of leg members having. Further, a loading platform may be provided above the base via a vibration damping means. Furthermore, a plurality of the bases provided with the leg members are arranged in parallel and attached to the lower part of the loading platform.

[0006]

[Operation] By vibrating the base, the leg members connected to it also vibrate. At this time, the tips of the leg members are in contact with the floor at a certain angle, so each vibration A repulsive force is generated when it leaves the floor. The repulsive forces of the respective leg members are combined into a combined force, which becomes a propulsive force for the base and the loading platform.

[0007] In addition, the vibration of the bases installed in parallel,
The loading platform can be rotated by adjusting each base independently.

[0008]

[Embodiment] Next, an example of a configuration for concretely carrying out the present invention will be described below. FIG. 1 is a side view showing the present embodiment apparatus, and FIG. 2 is a right side view thereof. FIG. 3 is a side view showing another configuration example of this embodiment, and FIG. 4 is a right side view thereof. Reference numeral 1 denotes a base, which has a flat plate shape and is made of a suitable hard material such as metal or resin. A vibration generating means 2 is coupled to an end (right end in drawing) of the base 1 by a structure capable of transmitting vibration. The vibration generating means 2 includes a conventional mechanism, for example, an electromagnetic oscillator or a mechanism using a piezoelectric element.
Alternatively, a mechanism in which the eccentric weight is rotated by a motor is appropriately selected. Note that the mounting position of the vibration generating means 2 is not limited to the above-described position as long as the vibration can be transmitted to the base 1.

On the lower surface of the base 1, a large number of leg members 3, 3, . They are also installed and fixed so that they are planted at regular intervals. The leg member 3 is attached to the base 1 or to the floor 5 at an angle Θ that is smaller than perpendicular.

[0010] The configuration for attaching the leg member 3 to the base 1 is not limited to the above configuration, and various configurations are possible. For example, as shown in FIGS. 3 and 4, instead of installing each leg member 3 individually on the base 1,
The leg member 6 may be integrally formed of elastic resin or the like and fixed to the lower surface of the base 1 by adhesive or screwing. Further, the leg member 3 is not limited to a plate-like member as described above, but as shown in a cross-sectional view of the main part in FIG. It may also be planted like a brush on a brush.

[0011] Next, although the present invention functions satisfactorily with the above configuration even when objects to be transported are loaded on the top surface of the base 1,
Further, a loading platform 9 is attached to the upper surface of the base 1 via vibration damping means such as a spring 8. This is because the vibration of the base 1 is absorbed by the loading platform 9 by using the spring 8 as a vibration damping means.
The transported object 10 from the loading platform 9 is
The purpose is to prevent it from slipping down.

[0012] This vibration damping means includes a spring 8.
However, the present invention is not limited to this, and an elastic material such as rubber or sponge may be interposed between the base 1 and the loading table 9 as long as the above object can be achieved. Further, two bases 1 to which the leg members 3 are attached are attached in parallel to the loading platform 9, and a vibration generating means 2 is attached to each base 1, respectively.

Furthermore, the power supply to the vibration generating means 2 is as follows:
This is carried out by attaching a power supply contact 11 to an appropriate location on the base 1, and supplying power from a wire track 12 embedded in the floor surface 5.

[0014]

[Operations of the Embodiment] With the structure described above, the present embodiment operates as follows. The vibration generated by the vibration generating means 2 is transmitted from the base 1 to the leg member 3. As a result, the tip portion 13 of the leg member 1 repeatedly comes into contact with the floor surface 5 at a minute distance due to vibration. At this time, since the tip portion 11 is in contact with the floor surface 5 with an inclination of the angle Θ, when it leaves the floor surface 5, it moves away in a repulsive manner. This repulsive force is generated for each leg member 3, and this force is combined to become a propulsive force, and the base 1, loading platform 9
, and the transported object 10 are horizontally moved in a certain direction. Here, if the leg member 1 is tilted rightward by an angle Θ as shown in FIG. 1, it will move in the direction of arrow a.

Furthermore, since two bases 1 having the above structure are attached to the loading platform 9 in parallel, if both are vibrated at the same time and to the same extent, they will move linearly. When the vibration of one of the bases 1 is stopped or the vibrations are weakened, the base 1 moves while turning in the direction of the stopped or weakened base 1. This results in
The direction of movement can be controlled as appropriate.

[0016]

[Effects] By configuring the present invention as described above, the following effects can be achieved. Since the propulsion mechanism relies on the repulsive force of the leg members rather than wheels, the structure can be simplified, and since there are no rotating or other moving parts, there is less chance of failure, making it highly reliable. .

Furthermore, by adjusting the length of the leg members, it is possible to create a so-called low-floor type in which the distance from the floor to the loading platform is short, making it easier to load and unload objects and improve work efficiency. be able to.
