Description

[Detailed Description of the Invention] This specification is related to the steel material tracking device, and is related to the steel material tracking device.
This invention relates to a copper material tracking device when a crane "lifts up or hangs steel material," and thus moves the steel material.

Movement of steel materials in the steel yard management system 1-=i
Since then, the operation has been carried out manually while being visually monitored by the operator. Therefore, it is extremely troublesome for an operator to memorize or record where the steel material is located in the steel material yard, and there is a risk of malfunction. Furthermore, given the reality that labor-saving is desired, operators must always monitor and manage the movement of steel without making mistakes.
It is therefore an object of the present invention to provide a steel tracking device that eliminates these drawbacks and inconveniences.

This invention will be described below.

In FIG. 1 showing an embodiment of the present invention, 1 is a computer that sends the output data of an electronic computer (hereinafter referred to as a computer) 2 to the crane side, and a ground side or guidance radio device that receives data from the crane side. The computer sends output data to the 2Fi crane and inputs data from the crane to track the movement of steel materials. In addition, data from the 3Fi crane side is sent to the ground @CC, a guidance wireless device on the crane side that inputs data from the ground side, 4 is equipped with a drive motor 5 for lifting and lowering the crane, and a contactor, auxiliary relay, etc. 6 is a steel adsorption detector attached to the riff magnet 7, and 7 magnet 7 is the relay board 4f.
In such a configuration, the steel material adsorption detector 6 is configured with a limit switch that becomes a bud when a copper material is adsorbed and turns off when the steel material is released. There is. The detection signal of the material adsorption detector 6, the contactor signal of the drive motor 5 for the crane lifting in the relay key 4, and the auxiliary relay signal are all sent to the computer via the Nishikimashi equipment 3 and 1. O sent to 2O These signals determine whether the computer@2dfA material has been lifted from the yard or whether the steel material has been suspended to the yard, and when it has been lifted, the steel material data is sent to the yard data, which will be described later. Transfer from the table to the crane data table, and when suspended, transfer the steel material data from the crane data table to the yard data table.

On the other hand, the position of the crane is determined by the configuration shown in FIG. Figure 2 1: As shown, the yard where G2 steel materials are loaded is I.
The yards are divided into 5 addresses A to 27A, and sensors IB to 105B for detecting the crane position are installed at each yard address.

When the crane moves and turns on these sensors IB to 105B, an interrupt signal is input to the computer 2 via the guidance radio devices 3 and 1. This allows the computer 2 to always remember the crane position. For example, if sensor IB or 2B is turned on, it can be stored that there is a crane at yard address IA, and if any of sensors 3B to 6B is turned on, it can be stored that there is a crane at yard address 2A.

This interrupt signal from sensors IB to 105B causes the computer 2 to
remembers which yard address C2 the crane is located at and determines the yard address when lifting or suspending steel materials.

By the way, when the crane hoisting signal is input, the computer 2 first checks whether or not the steel material adsorption signal is an on signal. Before the crane hoisting signal is input, the steel material has not been adsorbed, and if the copper phase adsorption signal becomes ON No. M, it means that the steel material has been lifted from the yard address where the crane is currently located. ≦Two zero If the C steel material adsorption signal is off when crane hoisting No. 48 is input, and the crane hoisting was in a state of adsorbing copper material before the signal was input, then The steel material was lowered to the yard address where the crane is currently located.

On the other hand, as shown in Fig. 3, the double calculator 2 has a data table (a yard data table and a crane data table) for storing data on each yard address and the copper materials accommodated by the crane. ing. When the crane lifts the steel material, the steel material data is transferred from the yard data table where the crane is located to the crane data table, and when the steel material is lowered, the data is transferred from the crane data table to the yard data table where the crane is located. Move to the table.

FIG. 4 shows the steel materials in the yard (FIG. 4A) and the state of the steel material data in the yard data table (FIG. 4B). Figure 4 Al2, No. 1-2-Material a3. When steel materials a2 and steel materials a1 are loaded, the steel material data of steel material a3 is written to the second area (each yard C: the maximum number of sheets that can be loaded is k) in the yard data table at address 1. The steel material data of steel material a2 is written to the -1st area, and the steel material data of copper material a3 is written to the k-2nd area.

Area 1-31r has no steel material data and is empty/state C-.

When the steel material is lifted from address 1 in this state, the topmost copper material data in the yard data table for address 1, that is,
Move the copper material data a1 from the k-2nd area to the crane data area, and empty the k-2nd area.

Also, when a steel material is hung at address 1, the steel material data a1 in the yard data table for address 1 is obtained from the crane data table.
The crane data table is emptied by moving it to the area of 1' and 2nd to the area of the next lower address to 13th.

The actual movement of steel material is as follows. When the crane is moving from yard address IA to yard address 2^ to address 4A, the computer 2 first controls the movement of the crane to move it directly from yard address IA to yard address 2. Output a signal. The crane is separated from sensor IB.
Do not turn on the sensors up to sensor 5B and stop after turning on sensor 5B. W from sensor signal ζyu
Calculator 2 learns that the crane has been moved to Yard Address 2.

Next, a descending control signal is output to hang the magnet 7 between the cranes t and '4411j2tj. When the crane glue 7 magnet descends and comes into contact with the steel material (hereinafter referred to as layer ratio), the descending of the magnet moxibustion door 7 stops. The electric machine 2 beam magnet lowering signal stops, and it is determined from the i2 that the riff magnet 7 has landed on the floor, and it outputs an excitation control signal to the riff magnet 7 to attract the steel material, and then A lift control signal for lifting the riff magnet 7 is output. From this point, the crane picks up and lifts the steel materials of the two people at the yard address.

Thereafter, the computer outputs a movement control signal to move the 2Fi crane from yard address 2 to yard address 4A. The crane turns off the sensors from sensor 5B to sensor 13B in order, then turns on sensor 13B and stops. From the sensor signal C, computer 2 learns that the crane has moved to yard address 4Al:.

Next I: The computer 2 outputs a lowering control signal for suspending the riff magnet 7 to the crane. At this time, when the crane lift magnet 7 descends and lands on the floor, the signal for lowering the lift magnet is stopped. Therefore, the computer 2 outputs a riff magnet 71: release control signal in order to release the steel material.
Next I: The computer 2 outputs a lift control signal to lift the lift magnet 7 to the crane. As a result, the crane has suspended the steel material to the yard address 4A, the detection output of the steel material suction device 6 is turned off, and a crane hoisting signal is input to the computer a2.

As described above, the steel materials at yard address 2 can be moved to yard address 4A using the control signal from computer 2 and the input signal 12 from the crane.

Now, when the crane is turning on sensor number 5B (yard address 2A), the signal for C crane hoisting is not manually operated.
'vIL computer 2 checks whether the steel material adsorption signal is an on signal or not. If the copper material adsorption signal becomes an off signal and there is no steel material in the crane data table, the yard address is 2A.
This means that the steel material was lifted from the Therefore, the copper material data in the youngest data area in which steel material data is written is from the first data area to the * data area of the yard data table shown in #g4 of Figure Bt2 of Yard Data Table 2A. to the crane data table. Then, the crane moved and sensor number 12B (
If a crane hoisting signal is input after turning on the yard address 4A), the computer 2 checks whether or not the steel suction signal is on. If the copper material adsorption signal becomes an OFF signal and there is steel material in the crane data table, this means that the steel material has been unloaded to yard address 4A. Second, the steel material data in the crane data table is written in the yard data table from the 1st data area to the Xth data area shown in Figure 4B at address 4A of the yard data table. Move from the younger data area to the one younger data area. In this way, the crane moves the steel materials from where to where in the yard address sequentially.

As described above, according to the steel material tracking device 52 of the present invention, since the address of the steel material in the steel material yard can always be stored, reliable tracking of the steel material is possible. In addition, all steel materials are tracked automatically, so there is almost no need for operator effort.

Incidentally, in the above explanation, C2 was explained when the steel material yard was divided into addresses IA to 27A, but this can be arbitrarily selected. In addition, each address C: sensor IB to be provided
105B can also be selected arbitrarily”0
