Application of bar code technology in fine chemica

  • Detail

The fine chemical industry is one of the basic industries of the national economy. At present, a relatively complete fine chemical industry system has been formed, mainly including surfactants, cosmetics, photosensitive materials, coatings, dyes, fluorescent brighteners, organic pigments, spices and pesticides

fine chemical industry is a process industry, which mainly adds value to raw materials through physical or chemical methods such as mixing, separation, crushing, heating, etc. Through many years of practical experience in information construction, I have summarized three particularities of the fine chemical industry: batch tracing, weighing management, formula confidentiality, which are also the three management problems of the fine chemical industry. Even after being installed in the ERP enterprise information system, it can not reach 12% To completely solve the problem, on the contrary, because of the large amount of information collected, the errors of manual operation and the delay of information input, the information of ERP system is not timely and accurate, which affects the enterprise management and decision-making except for the factors of uneven installation

the workflow of a fine chemical factory is roughly divided into raw material receiving, inspection, shelving, warehouse moving, microcomputer controlled cup burst cup tester {Shandong Sida high tech} production picking, batching, packaging, finished product warehousing, etc. because most of the raw materials, semi-finished products and finished products in the fine chemical industry are fluid characteristics, material weighing, the collection and input of a large amount of weighing data will be involved in most links, Tedious and error prone; The fine chemical industry has high requirements for quality traceability. The collection of raw material batch information in each link, including first in first out control, is also a problem that puzzles managers

formula is the life of fine chemical industry. In many chemical plants, the formula is only in the hands of core personnel. The packaging is replaced from the raw material receiving link, the raw material name and supplier information are hidden, and only the code is used for marking; In the ingredient link, a formula is divided into several parts, prepared by different groups, and then synthesized. Because the picking and batching are subject to the code, and the formula needs to be separated and synthesized, which puts forward higher requirements for workshop management. When batching, the material number, weight and batch records need to be checked. The operators need to have a high working heart and should not be careless

the barcode technology is applied to the fine chemical industry, and the batch traceability is calculated by using the rising spectrum formula: a1=, weighing management, formula confidentiality, three management problems can be solved

for batch traceability, it is necessary to establish the barcode label of raw material batch, and scan and collect the batch information in each material transfer link to achieve the purpose of batch traceability. The barcode label can require the supplier to print and paste according to the specified format and then deliver the goods (in this way, the data acquisition equipment can be used to receive the goods, and the efficiency of raw material receiving can be improved at the same time), or it can print and paste the labels by itself in the receiving link; In the following logistics links, such as inspection, shelving, stock transfer, picking, batching, etc., it is necessary to use collection equipment to collect batch information, and directly import it into the computer to generate relevant documents, so as to ensure the accurate recording of batch information, so as to ensure the continuation of batch information. Moreover, the collection equipment can monitor the first in first out operation of materials and judge whether it exceeds the shelf life, which effectively improves the standardization of warehouse operation

the following two figures are examples of central warehouses and workshop warehouses. The central warehouse adopts location management (also adopts barcode), and each material barrel has a batch barcode label; The workshop warehouse adopts unified material barrels, each of which has a material barcode label. The batch information is scanned and collected during picking, and transferred in the system to ensure the continuation of batch traceability

at present, electronic scale equipment is equipped with serial port RS232 output function, which can output weighing data to computers and other processing equipment. In the production picking, batching and other links that need weighing, the weighing data is automatically read by the computer and directly recorded into the relevant documents, which not only improves the work efficiency, but also avoids manual intervention in the data, ensures the accuracy and reliability of the weighing data, and improves the management level

the manual formula is discarded in the ingredient link, and the electronic formula can effectively prevent the leakage of the formula

for example, in the following operation workshop, the formula is set and split by the senior management and sent to each batching station. The operator selects the formula sheet and carries out the batching operation. Each step (what material to be prepared, how much to prepare, process requirements, etc.) is instructed by the computer. Before batching, the barcode of the barrel is scanned to confirm the correctness of the material, and the batch information is transmitted at the same time; The weighing data is automatically recorded on the computer, compared and passed within the allowable error range; Each batching bucket also has a barcode number, which is synthesized according to the system instructions. In this way, through the organic combination of information system and bar code application, the management specifications can be effectively implemented, and the operators can complete the work with quality and quantity

with the development of information construction in the manufacturing industry, the fine chemical industry has also generally adopted the enterprise ERP information system to improve its management level. If it can be combined with the application of bar code technology, it will greatly improve the effectiveness and real-time performance of the information system and make the enterprise management to a higher level
