Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a paint which is improved so as to be able to cope with the trend in which the demand for paints is increasing in variety and in small quantities.

Generally, paint is produced by using a paint manufacturing tank and a stirring device that can move up and down, and after putting the specified paint raw materials into the paint manufacturing tank, sufficient stirring is performed to ensure that each raw material is evenly dispersed. Manufactured. If the paint manufacturing tank has a large capacity, this tank is often of a fixed type, and the manufactured paint is transferred directly to other containers such as cans for sale by means of a pump. . On the other hand, when using a small-capacity paint manufacturing tank, attach running wheels such as casters to the tank so that it can be moved, and after the paint manufacturing is completed, move the tank to the paint filling workshop and fill it with paint. is being carried out.

In addition, when manufacturing paint, work such as preparing (mixing) various raw materials, stirring, and filling the manufactured paint into sales cans is often performed around the paint manufacturing tank. These work processes are considered as one block, and when manufacturing many types of paints, the current situation is that they are manufactured by type using a large number of installed blocks. According to this conventional method, it requires a lot of equipment and labor to distribute the raw materials to each block, especially when it comes to preparing various raw materials.In addition, after filling the manufactured paint into sales cans, etc., each block is Complicated transportation work is also required, including the work of picking up the goods and shipping them. In addition, recently, demand has been diversifying, and the demand for paints has become more pronounced with a tendency toward a greater variety of products in smaller quantities, and the number of paints manufactured in small to medium-sized quantities is increasing.

In view of the above points, the present invention consolidates the preparation process of paint raw materials, the stirring process, the filling process of manufactured paint, etc. into each process, and the transition to each process is remotely controlled by unmanned automatic transportation. The purpose is to improve the paint manufacturing method carried out by a paint manufacturing tank that is carried on a vehicle and to provide a rational manufacturing method that can handle the manufacturing of small to medium-sized paints of a wide variety of products. The purpose of this is to provide a station for each of the above steps in a paint manufacturing method that includes the preparation process of paint raw materials, the stirring process of the charged paint raw materials, and the filling process of transferring the manufactured paint to sales cans, etc. , the paint manufacturing tanks used for each process are loaded onto an unmanned automated guided vehicle, and this automated guided vehicle is remotely controlled by instructions from a computer based on a pre-written program to carry out each of the above steps. This is achieved by a method for manufacturing a paint, which is configured to travel between each station, and to sequentially move the paint manufacturing tank between the stations in accordance with the process order.

The manufacturing method of the present invention will be explained below with reference to the accompanying drawings. 1 is a paint raw material preparation process section;
3 is a stirring process section, 3 is a filling process section for the manufactured paint, and 4 is a tank stock section in which an empty paint manufacturing tank t is stored. A stock conveyor 5 for temporarily storing cans for sale, etc.) and a carry-out conveyor 6 for shipping are sequentially connected, and the tank stock section 4 is connected to a paint manufacturing tank t for cleaning as necessary. A cleaning section 7 is included for cleaning. Therefore, the preparation process section 1, the stirring process section 2, the filling process section 3, and the tank stock section 4 are comprised of a large number of stations 1a, 2a, 3.
A and 4a are respectively provided, and a paint manufacturing tank t is sent to each station 1a, 2a, 3a and 4a. In addition, these stations 1
A running path 8 for an automatic guided vehicle 11 (to be described later) is constructed between A, 2a, 3a, and 4a, and the automated guided vehicle 11 is controlled remotely by instructions from a computer based on a program created in advance. It travels on a travel path 8 and transports the loaded paint manufacturing tanks t to each of the above-mentioned stations according to the manufacturing process.

The automatic guided vehicle 11 has a chassis 11 as shown in FIG.
It is equipped with a rolling device 11b on top a, and is configured so that the paint manufacturing tank t can be easily delivered to each of the aforementioned stations 1a, 2a, 3a, and 4a, and taken out from these stations.
The transfer operation is carried out by an operating mechanism built into the automatic guided vehicle 11 (illustration and explanations are omitted), and the automatic guided vehicle 11 is guided by a guide provided on the travel path 8 to ensure its trajectory.

In the figure, 9 is a waiting path for automatic guided vehicles connected to the traveling path 8, 12 is a rolling device provided at each station, 13 is a stirring device placed at each station 2a of the stirring process section 2, and 14 is a filling device. Although not shown, each station 1a of the preparation process section 1 is provided with a paint raw material injection device, and each station 3a of the filling process section 3 is provided with a filling device.

As can be understood from the above explanation, in the manufacturing method of the present invention, as the first step, a large number of stations are provided in the preparation process of paint raw materials, and various raw materials are prepared using paint manufacturing tanks sent to each station. In addition to eliminating work such as distributing and transporting various raw materials, it also performs comprehensive management of various raw materials. Next, in the second stage, a large number of stations are installed in the stirring (dispersion) process, and the paint manufacturing tank with the raw materials loaded is transported to each station. Set the stirring time and perform stirring work under intensive work management. Furthermore, in the third step, the paint manufacturing tanks that have been agitated are sequentially transported to each station in the filling process, and the manufactured paint is filled into various types of sales cans according to demand, and these sales cans are Transfer to the logistics line for shipping.
The paint manufacturing tank, which has been emptied after the paint has been discharged, is transported to a cleaning section as needed, and after being cleaned, it is temporarily stored in a stock section.

In this way, a cycle ends,
The movement of the automatic transport vehicle and the work at each station in each process are all performed by remote control using instructions from a computer, etc., making it possible to achieve full automation of paint manufacturing.

Additionally, the unmanned automated guided vehicle is equipped with various sensors and safety devices to protect against obstacles.

The present invention is as described above, and it is easy to rationally integrate each process and control the work.In addition, in terms of management, information on each process can be reliably obtained, and pre-programmed operation management, Other controls have become easier, making it effective for manufacturing a wide variety of paints in small quantities.This is a groundbreaking method for manufacturing paints that can respond to diversifying demand. The practical effects are extremely large.
