Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chicken and egg transported on a cargo truck such as a large truck or a railway car.
The present invention relates to a pneumatic fluid type low-vibration container capable of transporting a load sensitive to vibration, such as fresh food products such as beer, milk and wine, liquid products, and precision equipment.

[0002]

2. Description of the Related Art Vibration isolation measures for a prior art container include vibration reduction of a vehicle drive mechanism such as an air suspension mechanism and an active suspension mechanism, and low vibration of an engine and a power transmission mechanism. Trucks and vehicles with low volume are used, and the vibration of the container itself is hardly reduced. In some fields, flexible cushioning is provided around the container or around the truck to transmit the vibration to the container. There were only some cases of relaxation.

[0003] Anti-vibration measures for the prior art container include:
There is a low vibration container described in Japanese Patent Application No. 10-225719, in which an outer box is placed on a truck of a transport vehicle such as a truck, and a rigid upper spring member having a long deflection length from the ceiling in the outer box is used. The container body for storing transported goods is supported, a vibration insulator is disposed between the lower part of the container body and the lower part of the outer casing, and the main weight of the total weight of the container body is fished by the plurality of upper spring members. The vibration insulator is used to support the remaining total lower load.

[0004]

As a countermeasure against vibration of the prior art container, the vibration of the container itself is hardly reduced, and in some fields, a flexible cushioning material is provided around the container or on a truck. Therefore, it is not sufficient to reduce the vibration of fresh food, liquid products, or precision equipment stored in the container. For example, in the case of chicken eggs, which is a representative material of fresh food,
It has been reported that the deterioration of the freshness inside the eggs becomes extremely large by transportation for about 10 hours, and there is a problem that the quality of liquid foods such as beer, wine, milk and the like is deteriorated.

In the low-vibration container described in Japanese Patent Application No. 10-225719, a rigid upper spring member is used. Therefore, when the natural frequency is lowered, the elongation increases, the strength becomes insufficient, and the weight becomes excessive. The gap between the side of the container body and the outer box acts as a vibration obstacle, so that sufficient amplitude cannot be obtained. If the width of the container body is made small, the gap can be made large. The characteristics of the upper spring member are difficult to adjust, and a vibration insulator is used to absorb the front, rear, left and right vibrations.

[0006]

In order to solve the above-mentioned problems, a pneumatic fluid type low-vibration container according to the present invention comprises a vibration absorbing device for absorbing vibration in three-dimensional directions of up, down, left, right, front and back. It is installed at the lower part of the main body and adopts pneumatic fluid system in three dimensions. The vibration absorber consists of multiple vertical vibration absorbers and horizontal vibration absorbers. Each vibration absorber has a piston and cylinder function. The compressor is characterized in that a predetermined volume of compressed air is filled in a constant volume container, which is communicated with a variable container having the orifice-type pipe resistance through a pipe having a pipe resistance.
