Hollow billet: the form of perforation back material; ,
Hollow forging: the form of material behind the winding arbor extraction press;
Steel pipe: the form of material behind the sizing mill;
Son pipe: the form of material after the comb sawing.
Female pipe body has four kinds of material forms, and zones of different is called pipe, hollow billet, hollow forging and steel pipe respectively aborning.It is pipe that pipe is prepared the heating zone, and the rolling deformation district is hollow billet, hollow forging, steel pipe, and finishing 1 district is steel pipe and son pipe.Finishing 2 districts are the son pipe.
Generally, pipe is man-to-man relation from the pipe to mother, and managing the child pipe from mother is many-one relationship.According to the difference of each regional material form, the present invention is divided into female tracking and son pipe tracking two parts of managing with the material tracking of whole production line, and following principle is summarized respectively as follows:
1, the following principle of single arm is as shown in Figure 3.
As shown in Figure 3; It is identical to single arm tracking ultimate principle that pipe is prepared heating zone, rolling deformation district, finishing 2 districts; When single arm runs to the one's respective area, the Database Systems autoscan detects, and detects the assembled state (being ON or OFF) of detecting elements such as different parts HMD, CMD, magnetic switch on the rolling line; Thereby differentiate steel pipe traffic direction and steel pipe actual motion position automatically; Distinct device one-level computer system PLC actual production information in the tracing area of automatic reception simultaneously generates female pipe automatically and follows the tracks of key word, and tracking data is stored automatically.
After this arm is followed the tracks of end; The Track Date Central Table of this arm is automatically moved to next tracing area with the tracking pointer gauge; And through Database Systems, this arm tracking result information is passed to the quality analysis control system automatically carry out analyzing and processing, prepare simultaneously lower branch line is followed the tracks of.
Female pipe is followed the tracks of and the data management scope: get into the pipe area in preparation from single arm, go out the cold bed district to single arm till.Server receives single pipe and reaches the standard grade behind (ploughing under saw back pipe intermediate transportation roller-way) signal; Database Systems are provided with corresponding steel pipe number (being female Guan Hao) for it, in mother manages tables of data and female pipe tracking pointer gauge, set up female data recording of managing respectively and follow the tracks of pointer with female the pipe.The corresponding female pipe data recording of each pipe is followed the tracks of pointer with female pipe.When mother's pipe moved on production line, the tracking pointer of female pipe can move in following the tracks of pointer gauge, is used to refer to out the position at the current place of steel pipe.
Female pipe pipe number definition: be made up of (lot number+rolling serial number in criticizing), it can uniquely confirm every steel pipe.
Female pipe tables of data: deposit steel pipe in the computational data in this stage and the measured data that is obtained.
Female pipe is followed the tracks of pointer gauge: the female pipe of real time record is in production line actual motion position.
Mother's pipe is followed the tracks of and is belonged to the present invention's single arm tracking generally speaking, follows the tracks of and in particular cases follow the tracks of two kinds of situation under the branch normal condition, and narration is as follows respectively:
Female pipe is followed the tracks of under the normal condition: when single female Guan Youshang one regional single devices got into next regional single devices, steel pipe was " first in first out " in proper order, and every steel pipe front and back position does not change with order.
Mother in particular cases manages tracking: it is more special that ring oven and cold bed list arm are followed the tracks of both of these case, and the steel pipe order possibly be " first-in last-out ", and every steel pipe front and back position has variation with order.
When ring oven adopts double mode material loading, first pipe A
1Lean on into burner hearth (away from fire door) when going into stove, second pipe A
2Lean on into fire door when going into stove.When coming out of the stove, second pipe A
2Go out first pipe A earlier

2, multiple length list arm (female pipe) cuttolength list arm (son pipe) following principle is as shown in Figure 4.
As shown in Figure 4, female pipe is become many roots pipe by sawing in finishing 1 district, and its tracing process is such; When mother manages after the cold bed cooling; By the blanking of cold bed outlet blanking device, get into finishing 1 district, the Database Systems autoscan detects; Detect the assembled state (being ON or OFF) of detecting elements such as finishing 1 district different parts CMD, magnetic switch; Thereby differentiate steel pipe traffic direction and steel pipe actual motion position automatically, the sawing information that simultaneously comb saw PLC transmits in the automatic reception tracing area, the pipe of female pipe number by lot number+batch in rolling serial number form; The pipe number that son pipe cutting sequence number constitutes the son pipe is dosed at its end automatically, and the tracking data of antithetical phrase pipe is stored automatically.
Female pipe is cut into the tracking of son pipe, belongs to the present invention's single arm in particular cases and follows the tracks of.Female pipe is cut into the tracking and the data management scope of son pipe: cut into the son pipe from the comb saw, till rolling off the production line to the son pipe.
Steel pipe is realized through child pipe tables of data and son pipe tracking pointer gauge after the comb saw is cut into sub-pipe.The corresponding son pipe data recording of each root pipe is followed the tracks of pointer with the son pipe.
After Database Systems receive the child pipe cutoff signal that comb saw primary PLC transmits, set up corresponding pipe number, son pipe data recording and son pipe for each son pipe and follow the tracks of pointer.When the group pipe moved on production line, the tracking pointer of son pipe can move in following the tracks of pointer gauge, was used for indicating the position at the current place of son pipe.Son pipe tables of data is used to deposit son and manages the computational data of in each zone of process production line (the comb saw is sheared the back) and the measured data that is obtained.
Number definition of son pipe: son pipe number is made up of (lot number+batch in rolling serial number+son pipe cutting sequence number), and it can unique definite each root pipe.
Son pipe tables of data: deposit the son pipe in the computational data in this stage and the measured data that is obtained.
The son pipe is followed the tracks of pointer gauge: real time record pipe is in production line actual motion position.
