Description

Cast tube quality tracing method and tracing system

Technical Field

The invention relates to the technical field of automatic quality tracing of cast pipes, in particular to a cast pipe quality tracing method and a tracing system thereof, and a preparation method of cast pipe socket cast word information.

Background

In the production, storage, transportation, installation and use processes of cast pipes, such as spheroidal graphite cast iron pipes, identification information such as specification and model, wall thickness grade or pressure grade, pipe number and the like of the pipes are generally presented on the end face of a pipe body or a socket in a code spraying mode. In the current production of cast pipes, the pipe number tracing of cast pipes generally adopts methods such as manual marking, one-dimensional code or two-dimensional code marking, RFID (radio frequency identification) and the like. And operators at the stations of each procedure manually fill in the quality information of the cast tube processed at each station, such as the weight of the tube, the size of a faucet, the hydraulic pressure, the pressure maintaining time and the like, according to the tube number information. If the quality information of a certain branch pipe produced in a certain day at a certain station is queried, the quality information needs to be queried from a quality archive, the query process is complicated, and the query time is long.

In the whole production, manufacturing, storage, transportation, installation and use processes of cast pipes, the existing production quality tracing mode of cast pipes cannot record and trace the quality information of the whole production process of each cast pipe accurately in real time. If the cast tube is marked uncleanly or is not easy to distinguish and once quality objection occurs, the production enterprises are difficult to quickly inquire the production quality information of the cast tube corresponding to the tube number, quickly judge the authenticity of the product and cannot accurately position the quality accident station and personnel. Therefore, once the quality tracing of the cast tube leaves the production site, the quality tracing of the cast tube is difficult to determine, and a production enterprise is difficult to trace the production quality information of the cast tube, so that the cause of quality accidents cannot be accurately analyzed, and the control and the improvement of the enterprise quality are difficult to be assisted.

At present, the method of manually marking, one-dimensional code or two-dimensional code marking, RFID (radio frequency identification) and the like is generally adopted for tracing the pipe number of the cast pipe, and tools such as a high-temperature resistant marker, high-temperature resistant ink, an electronic tag and the like are utilized to write, spray, paste and adsorb on the pipe body or the end face of a socket of the cast pipe, so that the operations such as number writing, number changing, repeated spray, repeated pasting and adsorption position changing are required to be frequently carried out by workers, the time and the waste are consumed in manual treatment, and the method is easy to make mistakes and be confused. The marking method is also easy to cause unclear marking or indistinct distinguishing due to improper placing position of the cast tube, scratched or shielded and corroded soil.

Therefore, the whole process from manufacturing, checking and selling of the casting pipe to the use of the user generates a large amount of information related to the product, the business process and the participators, and the production processing quality information, the checking quality information, the use quality information and the like have great significance for manufacturers and users. The key quality information of the cast tube in each stage of the life cycle of the product is accurately and timely acquired and transmitted, the real-time and rapid traceability requirement is met, and the quality management level of the cast tube industry is improved.

Example 1

Fig. 1 is a schematic flow chart of a first embodiment of a method for tracing the quality of a cast tube according to the present invention. In this embodiment, first cast information is recorded on a socket sand core for casting the cast pipe, and corresponding second cast information is formed on the socket of the cast pipe during casting. The cast tube quality tracing method provided in embodiment 1 includes:

step 101, acquiring and identifying the first cast word information, and generating the ID information of the cast tube based on the identified anti-body information of the first cast word information, wherein the cast tube ID information corresponds to the anti-body information of the first cast word information.

In this embodiment, the first cast information is a negative or positive cast information recorded on the socket sand core, specifically, a reverse body information of a character string, where the characters in the character string include, but are not limited to, characters, uppercase or lowercase letters, special symbols, and the like, and may be one or more of the above characters, combinations thereof, and the like. The first cast information obtained may be in the form of characters or pictures of the first cast information. The first cast information can be recorded in a plurality of places of the bellmouth sand core, such as the end face or the outer surface of the sand core, but the cast information is preferably recorded in the end face position of the bellmouth sand core, so that the information is more convenient to obtain and is not easy to be blocked or worn compared with other positions.

As described above, the anti-body information of the identified first cast information is a character string. The virtual pipe batch number data table is preset, different characters in the data table correspond to different data of the virtual pipe batch number, and according to the fact that the characters corresponding to the anti-body information of the first cast information are matched with the virtual pipe batch number data table, each character corresponds to preset data, and unique ID information of the cast pipe is formed.

In this way, the data integrity and integrity can always be ensured when establishing quality information relative to at least one subsequent production process.

It should be noted that under normal conditions, each process is to sequentially pass through the pipe, and the quality information of the cast pipe and the ID information of the cast pipe are sequentially corresponding and stored, so as to form the quality traceability information of the branch cast pipe. However, in the production process after the completion of the casting of the cast tube, there is a possibility that an abnormal situation such as a malfunction of production equipment or quality problems of the cast tube product occurs, and the cast tube is required to be treated off-line. Specifically, after the abnormal cast tube is offline, second cast information of the abnormal cast tube is acquired and identified, and isolation operation is carried out on the ID information of the cast tube.

And after the abnormal condition is eliminated, acquiring and identifying second cast information of the abnormal cast pipe according to the re-online sequence of the abnormal cast pipe, and identifying and activating ID information and corresponding quality information corresponding to the cast pipe.

In this embodiment, the first cast word information is recorded on the socket sand core, so that the setting of the second cast word information which are opposite to each other is realized on the cast tube, unique ID information of each cast tube is allocated according to the opposite body information of the first cast word information, and meanwhile, connection and storage are established between the second cast word information and the quality information of the cast tube, so that staff in each working procedure can store and record the quality information of the cast tube processed in each working procedure, such as tube weight, socket size, hydraulic pressure, dwell time and the like, according to the second cast word information of the cast tube. The quality information of the cast pipes can be called through the second cast character information of the cast pipes when needed, so that the production quality information of each cast pipe can be inquired anytime and anywhere in the process from the beginning of casting to the completion of the whole production process. And the production enterprises can analyze the quality condition of the cast tube in real time, and can optimize the production and manufacturing flow by combining the operation parameters of the process equipment, thereby improving the product quality and reducing the production cost.
