Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile liquid agent mixing apparatus capable of quantitatively mixing and transporting different types of liquid agents.

[0002]

2. Description of the Related Art Conventionally, when a paint is applied, a main agent and a curing agent, or a base paint and a colorant, which are pre-measured and separately sealed in a petroleum can (for example, a can), or a base paint and a colorant, are applied at a work site. Until the paint was obtained by opening the container and blending it.

When it is necessary to obtain a large amount of paint, such as when painting the hull, an operator weighs the main agent and the hardening agent, and weighs them at a predetermined ratio, for example, into a container of about 1000 liters. In some cases, paints are obtained by putting them in a large mixing tank and mixing them by a mixing mechanism.

[0004]

However, in the case of using a main agent and a curing agent contained in a measured petroleum can as described above, it is troublesome to open and mix the can. Also, disposal of a large amount of used cans causes environmental problems,
The solution was to be expensive. This problem is particularly serious when a large amount of paint is used. For example, it has been a serious problem in the primary rust-proof coating (painting of a shop primer) on steel for building a new ship.

On the other hand, when a worker manually prepares a mixed paint in a large preparation tank, it also takes time and effort. Although a technique for automating the mixing operation is also known (for example, Japanese Patent Application Laid-Open No. H11-151460), it is necessary to provide a large-sized facility, which requires a large cost. Further, since such a large-sized mixing tank is fixed at a predetermined position, the coating material that is filled and transported from a coating manufacturer, for example, into a drum can or the like, is mixed with the mixing tank (or an installation type coating connected to the mixing tank). (A holding tank), and when mixing for example by switching to a paint of a different color, it is necessary to wash the inside of the blending tank with a solvent or the like, and the workability is not good.

[0006] A similar problem may occur when a liquid agent other than the above-mentioned paint is mixed.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems. For example, it is an object of the present invention to appropriately mix quantitatively different types of liquid agents such as a main agent of a paint and a curing agent and to easily transport the same. It is an object of the present invention to provide a mobile liquid agent mixing apparatus which is widely used and relatively inexpensive, which makes it possible.

On the other hand, the other ends of the supply pipes 32 and 34 are preferably connected to the discharge-side openings of the pumps 32a and 34a via valves that can be freely opened and closed. The valve is preferably provided directly above the lid 22, and the amount of the liquid agent remaining in the supply pipe and being sent to the mixing container when the valve is closed to stop the supply of the liquid agent. To reduce. Further, for example, a socket or the like is provided at the opening on the supply side of the pump to form a connection end, so that the pump can be easily connected to a discharge port of a tank or a drum that holds a main agent or a curing agent. It should be noted that a diaphragm pump can be used as the pumps 32a and 34a.

The weight measuring device 36 is constituted by, for example, a platform scale such as a load cell, and can measure the weight of the mixing container 20 placed thereon. By subtracting the previously measured weight value of the mixing container 20 itself from the measured weight value measured by the weight measuring device 36, the weight of the liquid agent supplied into the mixing container 20 (supply amount) ) Can be calculated. In the present embodiment,
As described above, the amount of the liquid agent supplied into the mixing container 20 is measured by measuring the weight of the mixing container 20. In addition, flow meters are installed in the supply pipes 32 and 34. For example, various supply amount measuring means can be used.
