Description

Extraction guide device for sheet coil {Apparatus for guiding sheet coil}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal processing apparatus, and more particularly, to a drawing guide apparatus for thin coils used in a cold rolling process or an annealing process.

In the steel rolling process, more specifically, for example, in the bright annealing line of a stainless cold rolling mill, there is a mailing operation for charging a coil, releasing the loaded coil and transferring it to an annealing furnace.

One embodiment of such a mail order work is shown in FIG.

First, the coil C needs to be transferred to the pinch roll 4 after the coil C is charged into the tension reel 2.

For this purpose, one worker normally operates the switch on the operation panel 6 to raise the vertical swing table 8 with an inclination of 45 °, while the other worker grabs the released slip sheet 10 by hand to hold the paper wine. I work on the winder 12.

In general, when the thickness of the coil sheet is thick, the tip of the coil placed on the swing table remains loaded due to the strength of the sheet. However, when the coil thickness is thinner than 0.4mm, the coil tip is not transferred to the front of the swing table. Can not slide down.

When the coil tip falls down as described above, another worker must use the jig to catch the coil tip and then lift it up onto the swing table.

Therefore, the work is delayed due to the work of raising the coil tip back to the swing table, which leads to a decrease in product productivity.

Also, when passing through the pinch roll of the coil tip, another worker who handled the tip of the coil with the jig may be in danger.

In addition, at least three workers are needed for the mailing operation, and unnecessary manpower is consumed.

In order to solve these problems, an object of the present invention is to prevent the coil tip from falling back to the swing table with a slant when falling through the coil to prevent falling back, even without the operator's hand It is to provide an extraction guide device for a thin plate coil that can easily pass through.

The presser roll is arrange | positioned at the front side of the pinch roll 4 mentioned above, and the paper winder 12 for winding the slip paper 10 loosened by the coil C is located at the rear side of the tension reel 2.

A sensing sensor 18 is installed at an adjacent position of the paper wider 12 to detect whether the slip sheet 10 is completely unwound.

In particular, the tension reel (2) is rotated by a motor inside the electric box to release the thin plate (S) wound on the coil (C).

As shown in FIG. 2, the above-described guide device is composed of an access part 100, a pressing part 200, and a control part 300, which will be described in detail for each part.

The access part 100 includes a support plate 102 hinged to an upper end of the support beam 14, and an access control cylinder 106 installed on the bottom surface of the support plate 102.

The piston rod of the access control cylinder 106 is connected to the case to be described later to approach or retract the case toward the coil (C) during operation of the cylinder.

In order to smoothly guide the case during this approach or retreat, rails 104 are formed at both upper edges of the support plate 102.

On the other hand, the swing adjusting cylinder 108 is hinged to the support beam (14).

The piston rod of the swing adjustment cylinder 108 is hinged to the side position of the support plate 102 to induce the swing operation of the support plate 102 by pneumatic or hydraulic pressure flowing into the swing adjustment cylinder 108.

The case 202 of the pressing portion 200 is a cylinder which is penetrated in the front and rear direction so that a plurality of rollers can be driven therein, and the conveyance guide plates 202a and 202b are disposed up and down inside the case 202. It is arranged to face to ensure a smooth transfer path of the thin plate (S).

The rail jaw 204 corresponding to the rail 102 of the base plate 102 is formed at the bottom of the case 202.

The plurality of rollers described above are installed at the front side and the rear side of the case 202, more preferably one pair at the front side and the rear side, respectively.

The pair of rollers are a fixed roller 206 fixed to the lower portion of the case 202 and a push roller 210 capable of lifting up and down from the top of the fixed roller 206 to the fixed roller 206 side.

Here, the fixed roller 206 is connected to the motor 208 and the belt installed on the outside of the case 202 to receive power, the press roller 210 is a push adjustment cylinder (fixed to the outside of the case 202) 212) to raise and lower.

In particular, three defect prevention idle rollers 206a are arranged in close contact with the fixing roller 206.

These defect prevention idle rollers 206a are connected to each other by a belt at the outside of the case 202 and are simultaneously rotated when the fixing roller 206 is driven.

Then, an air supply pipe 214 is disposed below the fixed roller 206 and above the pressing roller 210 to inject air between the thin plate S and the slip sheet 10.

The air supply pipe 214 is provided with a control valve 214a to control the supply of air.

Meanwhile, the proximity sensor 216 and the plurality of position detection sensors 218 are installed at the front and the internal places of the case 202.

Here, the proximity sensor 216 located in front of the case 202 detects the position of the coil C when the case 202 approaches or retracts toward the coil.

The plurality of position detection sensors 218 are sensors for grasping the tip position of the thin plate S released from the coil C.

On the other hand, the control unit 300 is connected to the tension reel (2) and the plurality of sensors described above in accordance with the detection signal input from the tension reel (2) and the plurality of sensors the access unit 100 and the pressing unit 200 ) To control the operation.

The extraction guide device for the thin coil according to the present invention configured as described above exhibits the following actions.

First, the coil is charged to the tension reel 2, and the hydraulic pressure is supplied to the access control cylinder 106 in order to transfer the tip C1 of the coil C thus loaded, thereby bringing the case 202 to the coil C side. Advance

When the case 202 approaches the coil C while moving forward, the proximity sensor 216 detects the coil C, and the detected signal is sent to the controller 300.

The control unit 300 blocks the hydraulic pressure supplied to the access control cylinder 106 by the sent detection signal to stop the case 202. As a result, an appropriate gap is maintained between the coil C and the case 202.

Subsequently, when the tension reel 2 is driven by the operation panel of the controller 300, the front end portion C1 of the coil C is placed on the front fixed roller 206.

At this time, if the front position sensor 218 detects the coil tip portion C1, the detection signal is input to the control unit 300.

The control unit 300 operates the push adjustment cylinder 212 to down the front push roller 210, and at the same time to operate the control valve to supply air to the air supply pipe 214.

Accordingly, the air injected from the air supply pipe 214 separates the thin plate and the slip sheet from each other.

On the other hand, the down front pressing roller 210 and the front fixed roller 206 is in close contact with both sides of the thin plate CP, in this state the motor 212 is driven to rotate the front fixed roller 206 (CP) is advanced.

When the rear position sensor 218 detects the front end of the thin plate that has been advanced, a detection signal is sent to the control unit, and the control unit lowers the rear press roller 210 by operating the rear press adjustment cylinder 212.

The lowered rear pressing roller 210 is in close contact with the upper surface of the thin plate CP, and the rear fixing roller 206 is in close contact with the lower surface of the thin plate.

Then, when the fixed roller 206 is rotated by the motor 212 located at the rear, the thin plate CP is transferred toward the pinch roll 4, and when the pinch roll 4 reaches the pinch roll 4, the upper pinch roll 4 is lowered. To be in close contact with the thin plate CP.

The access control cylinder 106 then operates to retract the case 202.

As the retraction of the case 202 is finished, the front and rear press rollers 210 are raised, all the motors are stopped, and the air injected from the air supply pipe 214 also stops the injection, and the thin plate CP is delivered to the pinch roll 4. It is transferred to the pressner roll 16.

As described above, the preferred embodiment of the present invention substantially solves the conventional problems.

That is, since the coil is pulled out by using the pressing roller and the fixed roller while the case is approaching the coil side, unnecessary work of raising the tip of the coil to the swing table does not occur, thereby improving product productivity.

In addition, there is no need to use the jig to handle the tip of the coil, eliminating the danger of the operator when passing through the pinch roll of the coil tip.

In addition, since the mailing operation is performed by the machine, unnecessary consumption of manpower can be reduced.
