Description

Manufacturing system Technical Field The present specification discloses techniques related to manufacturing systems. In particular, the disclosure relates to techniques for manufacturing systems for manufacturing liquid chemicals. Background There is known a technique of stirring a liquid in a reaction tank to produce a liquid chemical substance. In the production of chemicals, it is necessary to adjust the state of the raw materials (for example, the concentration of a solution) in the reaction tank to a predetermined value. Patent document 1 discloses a technique of sampling a solution in a reaction tank, measuring the concentration of the sampled solution, and automatically adjusting the concentration of the solution in the reaction tank to a predetermined value. Specifically, water or a raw material solution is automatically supplied into the reaction tank based on the measurement result of the concentration of the sample solution, and the solution concentration is adjusted to a predetermined value. Prior art literature Non-patent literature Patent document 1 Japanese laid-open patent publication No. 1-171349 Disclosure of Invention Problems to be solved by the invention In order to confirm the progress of the reaction when a chemical substance is produced in a reaction tank, a solution may be sampled during production to confirm the reaction state. The sample solution is analyzed by an analysis device to confirm the reaction state. Then, based on the analysis result, it is determined to continue the reaction and change the reaction conditions of the reaction tank. During analysis of the sample solution and continuation of the reaction or change of the reaction conditions, the operation of the reaction tank needs to be stopped in order to suppress excessive reaction of the chemical substances. In addition, analysis of the sample solution takes time to analyze the analysis result. As a result, the production time of the chemical substance becomes long. The present specification aims to provide a manufacturing system capable of improving a manufacturing process of a chemical substance. Means for solving the problems The 1 st technique disclosed in the present specification is a manufacturing system, which may include a sampling device that automatically collects a sampling solution from a reaction tank, an analysis device that analyzes the sampling solution, and a control device that controls the sampling device and the analysis device. In this manufacturing system, sampling solutions are automatically collected and transferred to an analysis device, and conditions of a reaction tank are automatically adjusted based on analysis results of the analysis device. The 2 nd aspect disclosed in the present specification is the manufacturing system according to the 1 st aspect, wherein an adjusting device for adjusting a solution condition for analyzing the sample solution may be provided between the sampling device and the analyzing device. The 3 rd aspect disclosed in the present specification is the manufacturing system according to the 1 st or 2 nd aspect, further comprising a sampling bottle for storing a sampling solution and a cleaning device. The cleaning device automatically cleans the inside of the sampling bottle after the analysis of the sampling solution is finished. The 4 th aspect disclosed in the present specification is the manufacturing system according to the 3 rd aspect, wherein the cleaning device automatically cleans the inside of the sampling device after transferring the sampling solution to the analysis device.
