Description

[Detailed description of the invention] (Industrial application field) This invention is a paint that is installed in a simple wet painting booth, etc., and is used to supply various kinds of paint in small quantities to a painting gun in a relatively small amount. Regarding the supply device.

(Prior Art) Conventionally, when painting relatively small parts, a simple wet painting booth has been used and the painting has been carried out manually with a paint gun. Conventionally, in this wet-type simple painting booth, when changing the paint color, the paint tank had to be replaced each time, and transporting the paint tank for replacement was very troublesome. Therefore, the inventor of this invention
- In No. 183488, etc., a plurality of turntables are provided vertically at intervals along a vertical axis and are rotatable, paint tanks of various paint colors are installed on the turntables, and the rotation of the turntables is controlled. This paper proposes a multi-variety, small-quantity paint supply device that allows a paint tank of a desired paint color to be directed toward the operator, making it easy to change paint colors.

(Problems to be Solved by the Invention) The above-mentioned multi-variety, small-quantity paint supply device brings about a remarkable improvement in the workability of multi-color painting, and can sufficiently cope with the diversification of paint colors.

By the way, this equipment requires constant stirring of the paint in the paint tank in order to always prepare various types of paint in a ready-to-paint state, so each paint tank is equipped with an agitator or other agitator. Ta. However, in the past, the air drive device for operating each agitator was separately provided, making the overall structure of the device complex and requiring a large amount of air consumption, making it difficult to save energy. It was something I didn't like. Furthermore, since it is air-driven, it is extremely difficult to control the speed of movement of the stirring member to be constant for all paint tanks.

The present invention eliminates these drawbacks and further improves the above-mentioned proposed apparatus for supplying various types of paint in small quantities.

(Means for solving the problem) The multi-variety, small-quantity paint supply device of the present invention uses a gear mechanism to interlock all the mechanical agitators installed in each paint tank, and simultaneously stirs the paint in the tank. It has been made possible to do so. That is, the device of the present invention is a device in which a plurality of turntables are installed rotatably around a main shaft and spaced apart vertically, and a paint tank on the table is rotated by the rotation of the turntables. A main gear mounted freely, a secondary gear mounted on the rotating shaft of the agitator equipped with each paint tank, an interlocking shaft installed vertically so as to be freely rotatable and connected to a drive device, and the main gear and interlocking shaft. and a transmission mechanism that connects and transmits the rotation of the interlocking shaft to the main gear, and a detachable means for fixing each paint tank on a predetermined turntable so that the main gear and sub gear mesh with each other, and removing it. It is something to do.

The transmission mechanism in the present invention includes, for example, a belt drive mechanism, a chain drive mechanism, or a gear drive mechanism. A belt drive mechanism includes a pulley and belt combination, and a chain drive mechanism includes a sprocket and chain combination. The gear drive mechanism includes a plurality of gears that interlock with an interlocking shaft. Further, it is preferable that the attachment/detachment means consists of, for example, a pair of clamp members and their tightening/unfastening parts.

(Function) In the device of the present invention, the interlocking shaft rotates when the drive device is operated, and the rotational force of the interlocking shaft is transmitted to the plurality of main gears provided for each turntable by the action of a transmission mechanism such as a belt or chain drive. The main gears rotate around the main shaft, and the rotation of the main gears rotates the plurality of sub-gears located around it, and the rotation of the sub-gears rotates the plurality of paint tanks on the turntable. The agitators are activated respectively, so that the paint in the tank is agitated at the same time. In this case, by appropriately changing the power transmission ratio from the drive device to the interlocking shaft, the transmission ratio of the belt or chain drive mechanism, and the ratio of the number of teeth between the main gear and the secondary gear, the rotation of the agitator of each paint tank can be adjusted. The speed, or stirring efficiency, can be set to the desired level. Furthermore, in the device of the present invention, the paint tank can be replaced very easily due to the attachment/detachment means.
