Description

Stripper car coupled a measuring instrument and a indicator the distance for transferring a hot coil}

The present invention relates to a device for precisely controlling the position and stripping distance of a stripper car used to draw a hot rolled coil from a winder and transport it to a yard, and more particularly, a rolled strip wound in a rolling process of a hot rolled mill and a mini mill. When the coil is wound in a machine, the present invention relates to a stripper car device combined with a distance measuring and indicator for conveying a rolled coil, which draws the coil from the winder to transfer the wound coil to the yard.

In general, as shown in FIG. 1, the stripper car 10 pulls the coil 9 to move toward the station 13 in a state where the reverse end sensor 30 is operated. When the forward slow down sensor 32 operates, the stripper car 10 moves forward at a reduced speed to place the coil 9 on the station 13 after the forward end sensor 33 operates. When the stripper 10 moves back to the stand-by position, it uses a PI 51 to prevent a collision between the stripper car and the unit roll 8 that is operated when the coil is wound. Since the collision may cause a large-scale accident, PIL remembers the position of the stripper car so that the unit roll is kept in a safe position when it is open.

As a main problem of the prior art, as shown in FIG. 2, the electronic device 68 and the power supply for operation such as the light emitting diode 67, the light receiving diode 71, the transistor, the resistor, the capacitor, etc. (69), the rotary plate 70 to block the light and pass through it is possible to calculate the distance, the failure occurs due to vibration, temperature, moisture, etc., as shown in Fig. 6 the pinion pinion gear 53 PlG chain 54 connecting the stripper car wheel 102 and the corroded by high temperature and cooling water is broken.

Figure 3 shows the installation of a proximity sensor for detecting the position of the stripper car according to the prior art, the position where the stripper car is waiting to withdraw the coil coiled wound by the coolant and the high temperature coil used to protect the equipment during winding The coil 30 is delayed due to frequent failures due to corrosion, insulation abnormality, deterioration, etc. of the sensor 30, the reverse slowdown sensor 31, the emergency limit switch 35, and the like.

Therefore, there is a problem that the cooling water generated when the coil is wound to the various sensors 30 and 31, causing a decrease in output due to malfunction and failure due to poor insulation and failure of automatic stripper car operation.

The technique in the conventional stripper car is as follows.

Figure 4 shows a conventional stripper car not started, the Myrington automatic alarm device, if the operation was not performed within a given time due to various reasons in the process of withdrawing the coil, the driver finds it and takes appropriate measures to produce the work. The limit switch 62 and the proximity sensor 63 for detecting the operation of the stripper car 61 are attached in order to be made continuously.

FIG. 5 shows a conventional coil take-out rotating device of a down coiler, and a telescope generated in the inner and outer diameters of a wound coil improves a problem of deterioration in quality due to fold or cut-out during transportation. The rotating plate 64, the lower fixing plate 65, the hydraulic actuator 66, and the like are provided to rotate and transport the wound coil.

6 shows the installation of the PLG for detecting the stripper car position according to the prior art, where the position of the stripper car is a peg 51 used to prevent a collision between the stripper car 10 and a unit roll that operates when the coil is wound. The wheel 102 of the stripper car and the PLG pulley 53 are connected to the chain 54 to detect the chain. However, the chain may be broken by corrosion by the coolant, causing a prolonged production pause. There is a problem with a defect.

Therefore, the present invention has been made in order to solve the above problems, the present invention is to install the position control sensor Absocoder (Absocoder) in the stripper car which is a device for taking out the coil wound in the winder and transfer to the yard, the next process The distance indicator is installed at the driver's desk so that the driver can see the exact location of the stripper car, so that the stripper car can transfer the coil by manual operation even if it leaves the home position, thereby preventing the decrease in productivity due to the coil withdrawal delay. It is an object of the present invention to provide a stripper car combined with a distance measuring and indicator for rolling coil transfer.
