BACKGROUND OF THE INVENTION and Prior Art For example, a conventional method for producing paints, inks, etc., comprises a step of kneading and dispersing a predetermined pigment in a vehicle mainly composed of resin varnish and then adjusting it to form a paint. The primary colors of the paints are mixed and stirred to finish the specified color, and the sampling and quality inspection are roughly divided into two, toning and inspection processes, and many fixed tanks are installed in those processes. Generally, these tanks were connected by pipes. Further, a system in which a manual moving tank is used in place of the fixed tank and each operation is performed by the tank is also adopted. In any of these methods, depending on the product whose color tone and color quality such as paint and ink are the most important check items, complete cleaning of tanks and piping and elimination of contamination are indispensable. In the manufacturing site for paints, inks, etc., a large number of fixed tanks are arranged, and multiple pipes are arranged to connect these tanks, so the above work is extremely difficult and in most cases manual work It was the current situation to rely on.

On the other hand, since there is a demand for more efficient production and automation of production, innovative and completely different methods of producing paints, inks and the like have been sought and studied. Furthermore, in recent years, demand has been diversified and individualized, making it more unique and functional than conventional general-purpose products.

Since fixed equipment is centrally installed in each station so that predetermined work can be performed efficiently, the moving tank truck transferred to the station frame is connected to these fixed equipment with an automatic connection device and specified Work is performed, and when the work is completed, the work is moved to another station and the work is sequentially connected.
Therefore, this system completes the production in the same tank from the raw material feeding to each color matching, tempering process and product discharging process, so there is no risk of contamination and it is possible to produce a wide variety of products in small quantities. Since the production is carried out under control, a significant effect is expected in terms of automation and efficiency.

The operation time is different from each other along one side or both sides of the transport path 14 on which the automatic transport vehicle 10 travels through the color matching inspection station 3, the dispensing station 4, and the cleaning station 5 for performing the color matching, the quality adjusting work, the payout and the cleaning work. Since a plurality of transfer tanks 20 are installed, the transfer tank 20 is conveyed from above the standby station 6 by the operation of the roller conveyor 9 and the main raw material charging step is performed. It reaches the Shon 1 is stopped at a predetermined position by the positioning device. A large number of main raw material tanks A are provided in the vicinity of the main raw material feeding station 1, and the main raw material is fed into a moving tank 20 located in the main raw material feeding station 1 from a charging pipe 30 communicating with the tank A. However, at the time of this charging, the metering means provided in the station accurately measures the amount of the charging, and the above-mentioned charging pipe 30 is provided with a pipe end valve device 31, so that liquid drop or the like occurs. Not configured.

When the feeding of the main raw material is completed, the roller conveyor 9 is driven to convey the moving tank 20 to the adjoining auxiliary raw material charging station 2, and the auxiliary raw material is moved to the moving tank 20 in the same manner as described above.
Throw in. The above-described introduction of the main raw material and the auxiliary raw material requires substantially the same work time, and the work at each of the stations adjacent to each other by the roller conveyor 9 can proceed smoothly without any delay. If the roller conveyors that become stations are driven separately,
Even if there is some deviation in working time, it can be sufficiently covered. Transfer tank 2 with main and auxiliary materials
0 is transported from transfer station 7a to 7c via 7b.

The transfer tank 20 transferred to the transfer station 7c is an automatic transfer vehicle 10 traveling on the transfer path 14.
Reprinted in. Since the transfer rollers 12, 12, 12, ... Are rotatably mounted on the automatic carrier 10, the transfer of the transfer tank 20 can be easily carried out. Then, as described above, the color matching inspection stations 3, 3, ..., Discharging stations 4, 4, cleaning stations 5, 5 and the like having different working times are provided on one or both sides of the transport path on which the automatic transport vehicle 10 travels. Are provided and transfer rollers 12, 12, 12,
... is rotatably mounted. In this example,
The reason why the work stations with different working times are not provided on the roller conveyor is that if the stations with different working times are provided on the roller conveyor, the working time will be different for each station. In this case, since many moving tanks 20 always stay and smooth work cannot be performed, in this embodiment, a plurality of working stations are installed on one side or both sides of the transport path 14, and the moving tanks 20 are loaded between the working stations. The carrier 10 is run, the moving tank 20 is transferred to each station via the automatic carrier 10, and the automatic carrier 10 can carry other moving tanks during the operation. The transfer tank can be operated efficiently.

Further, the moving tank in which all the processes including the cleaning process have been completed is transferred from the cleaning station 5 or a temporary standby station 7d after completion of the process to the standby station 6 before the work via the ceiling rail 13 by the transfer device C. The transfer tank 20 is transferred. In the present embodiment, the moving tank 20 is transferred by the transfer device C using the hoisting ceiling rail 13 as described above. This means that computer color matching is used for color matching and tempering work. -Although a system (CCM) has been introduced, it is necessary for the worker to finally check the delicate parts, so in this embodiment, the moving tank 2 is provided to secure a passage for the worker.
0 is hoisted and the moving tank 20 is transferred by traveling on the ceiling. However, it does not matter if it is carried by an ordinary conveyor without adopting the lifting type.

As described above, the moving tank 20 loaded on the automatic carrier 10 is smoothly transferred to the color matching inspection station 3. Since the stirring device 70 with the lid 78 is installed near the color matching inspection station, the stirring blade 77
Is inserted in the tank 21 and the tank 21 is closed by the lid 78, and a predetermined work is performed. Since there are variations in the toning time depending on the specifications and brands, a plurality of toning inspection stations 3 are installed, and since the stirring device 70 is provided with a drop receiver 79, it does not pollute the environment. Stirring blade 77
May be washed in a washing tank. When the color matching inspection work is completed, the moving tank 20 is moved to the dispensing station 4, where it is weighed and filled in a predetermined shipping container. The empty transfer tank 20 moves to the cleaning station 5 and is cleaned by the automatic cleaning machine.

Since the moving tank 20 in this embodiment is an open type, a hood is provided above each station to prevent dust from entering and to exhaust gas, odor, etc. generated from liquid in the tank. .. In addition, since the production plan for each brand is entered in advance in the computer, selection of raw materials, production volume, tank capacity, tank movement, work time at each station, etc. are all automatically performed by the computer. Is. In this embodiment, seven stations are installed, but the stations can be installed arbitrarily depending on the production items, the number of brands, etc.
Since it is possible to easily add more, it is possible to mechanize the work that has conventionally depended on manual work, thus saving labor and improving efficiency.

[0039]

In the method for producing various kinds of raw materials using the moving tank according to the present invention, a plurality of stations having substantially the same working time are provided adjacently on the roller conveyor, and the working times are different from each other. Since a plurality of stations are installed on one side or both sides of the transport path on which the automatic transport carriage with the moving tanks transferred, the work at each station whose working time is approximately the same is on the roller conveyor, It is implemented very smoothly and the moving tank does not get stuck on the roller conveyor. In addition, for processes with uneven working time, the transfer tank is transferred and transferred by an automatic transfer cart, so the flow of production can be performed smoothly without delay, and the tank can be transferred to each station. Since the production is completed in the same tank while mounting, there is no concern about contamination, and there is no need to switch pipes due to changes in products, improving productivity. And, in the conventional "moving tank type multi-purpose batch production system", the apparatus is generally complicated and the operation tends to be complicated, and as a result, there is a tendency that the investment cost becomes high, but the method of the present invention is as much as possible. ， Since the mechanism has been simplified, by establishing production bases at multiple locations close to the market in the future and integrating them at one location, it is possible to produce directly connected to the demand with the minimum raw materials and product inventory. This is the most suitable method for small-quantity production and multi-product variable volume production.

The present invention is most suitable for the production of paints, inks, etc. which must be adapted to individual tastes.
Not only ink, but also many brands and specifications of organic and inorganic chemicals, foods, feeds, petroleum products, etc. If introduced into multi-product small-quantity production, multi-product variable production, its efficiency will be remarkable.
