Description

Wire Rod Falling Direction Control Device {APPARATUS FOR CONTROLING THE DIRECTION OF FALLING OF WIRE ROD COIL}

The present invention relates to a device for controlling the direction of falling of the wire coil, and more particularly, due to the load when the winding machine forms the coil by low temperature winding according to the control rolling, the ring shape of the rear end coil is unevenly formed and transported. The present invention relates to a falling direction control and a device of a wire rod for more safely transporting and winding coils.

In general, when the winding machine forms the coil by cold winding according to the conventional controlled rolling, the final rolled material leaves the drawer, and the ring shape of the coil does not come into close contact with the coil ring of the front end due to the decrease of the driving force and the increase of elasticity by heat. About 45 ° ~ 50 ° are injured and transported. More detailed description is as follows.

1 is a configuration diagram showing a transfer state and a winding form of a coil ring in a conventional control rolling, wherein the cold rolled material 1 emerges from the pinch roll 2 and the spiral of the winder 3 is in a low temperature state. The coil ring is formed by the pipe 3p. At this time, the coil ring of the rear end is dropped by floating by the θ (about 45-50 °) from the ring 10 'of the front end drawn out first due to the reduction of the driving force when the rear end of the rolled material 1 is released from the drawer. Typically, the number of rings at the rear end is about 5 to 6 rings, and is calculated as the length of the end point of the winder in the final mill roll.

The rear end floating coil ring 10 formed as described above may be caught on the mandrel 4 of the reform tube during the final winding process along the conveying conveyor roller 5. Therefore, such a rear end coil ring 10 has a problem in that it must be treated by non-water cooling or manually. That is, this is conventionally inducted by the non-water cooling method to increase the malleability in close contact with the coil ring of the front end portion or was finally wound by hand on the conveyor. In this way, by performing the cropping and trimming treatment of the non-water-cooled part through the parallel method, the error rate is lowered, a separate correction process has to be performed, and the manual work has been difficult due to the high temperature.

The present invention is to solve the above problems, in the state inclined in the ring direction of the front end by controlling the drop speed difference of the upper and lower coil rings after the take-off from the winder in the state that the surface defect does not occur at the front lower side of the winder By conveying, the object of the present invention is not only to transfer the coil more safely by changing to the same overlap density as the ring of the front end, but also to automatically perform work on the conveyor and to shorten a separate correction process.

It provides a wire rod falling direction control device that the coil is transferred to the conveyor in a uniform form.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 schematically shows the configuration and operation of the coil drop control device of the present invention, Figure 3 is a cross-sectional view of the strip guide portion of the coil drop control device of the present invention, Figure 4 is a tree of the coil drop control device of the present invention Fig. 5 is a perspective view of a coil crimp portion of the coil drop control apparatus of the present invention.

Coil drop control apparatus according to the present invention is composed of a coil guide portion formed of the tripping guide 20, the guide shaft 21 and the like and the coil pressing portion formed of the coil pressing roller 60, the cylinder 64 and the like. .

As shown in Figs. 2, 3 and 4, the coil guide portion includes a tripping guide 20 formed in an arc shape like the circumferential surface of the lower coil 100 at the lower portion of the winder (3). The tripping guide 20 forms a through hole 24 to allow the guide wheel to penetrate upward. Such through grooves 24 are preferably symmetrically formed about three through grooves in the center thereof, and the guide wheels 22 and 23 inserted into the through grooves 24 also include the guide wheels 23 in the center. Three may be formed of guide wheels 22 on both sides. Guide wheels 22 and 23 are fixed to the guide shaft 21 which is placed in the same direction as the axial direction of the conveyor roller 40 under the tripping guide 20. The guide shaft 21 inserts an arm 28 having two through holes formed at both ends thereof, and the guide shaft 21 is rotatably supported by the arm and centers the other through hole 29 of the arm 28. It rotates to eccentrically rotate the guide shaft.

The guide wheels 22 and 23 are grooved around the circumference, and a plurality of grooves are arranged at regular intervals. The reduction gear 30 is inserted and fixed through the other through hole 29 of the arm 28. The reduction gear 30 has a small diameter gear is formed on one side, a large diameter gear is formed on the other side, and is engaged with the gear of the other diameter formed on the shaft of the motor to rotate at a constant reduction ratio. However, the part connected to the motor 32 is a reduction gear on one side, and the reduction gear on the other side is only supported to be rotatable in the case 70 of the conveyor.

The pair of reduction gears 30 are supported by a case 70 and a bearing 34 of the conveyor. Preferably, the bearings use ball bearings. Therefore, the deceleration gear is inserted into one arm 28 through the other through hole 29 of the arm 28 in the case 70, but this does not actually play a role of deceleration, but is only fixed to the case to rotate the center of rotation. Will form a role. The guide shaft 21 is not fixedly inserted into the arm 28, but is rotatably inserted, but the reduction gear 30 is fixedly inserted into the arm, so that the through hole 29 is serrated. It is preferable to be formed in, it is preferable that the shaft of the reduction gear 30 inserted therein is also formed so as to be bite to the tooth.

Preferably, the guide shaft 21 extends to the opposite side to which the motor 32 is attached and protrudes outwards through the case 70. At the end of the guide shaft 21, the power transmission sprocket 42 is inserted and fixed. In addition, the shaft of the conveyor roller 40 lying under the tripping guide 20 is also extended to protrude to the outside of the case 70, the coil feed roller sprocket 48 is inserted fixed to the end of the protruding shaft. . These sprockets (42, 48) are caught by the chain 44, to hold the spacing sprocket 46 in the middle of the chain 44 to maintain the tension of the chain at all times, the spacing sprocket 46 is a tension spring Under 50, the tensile force is pulled outward. Such a configuration in which the guide shaft 21 is rotatable in accordance with the lower roller 40 maintains the speed of the lower part of the coil caught in the groove of the guide wheels 22 and 23 to some extent to advance the coil. To prevent interference. The tension spring 50 is attached to one side of the case 70.

The coil pressing portion is composed of a pressing roller 60 placed on the conveyor roller, an arm 62 supporting the pressing roller 60 and moving upward and downward, and a cylinder 64 attached thereto. The pressing roller 60 has the same width as the conveyor roller and is rotatably inserted at one end of the arm 62. One end of the arm is inserted into the arm 62, and the other end is inserted into and fixed to the bearing 66 so as to be rotatable to the case 70. Preferably, the pressing roller 60 is composed of two and arranged continuously at the end of the arm 62. The case 70 forms a gap to move the pressing roller 60 up and down, and the pressing roller 60 is rotatable at the connection portion of the arm 62 into which the pressing roller 60 is inserted. It is inserted in the axis of (60). One end of the cylinder 64 is inserted into the pin member 68 so as to be rotatable to the case 70.

Referring to Figures 2, 6 and 7, the action of the wire coil falling direction control apparatus according to the present invention as described above are as follows. 6 is a state diagram showing a control state in the coil drop direction, and FIG. 7 is a state diagram showing a coil crimping state.

When the final rolled material 1 leaves the drawer 2, the conveyor roller is powered by a material detector (not shown) to rotate the roller. The rollers are configured to be driven by the chain and are not shown separately in the drawings. On the other hand, the motor 32 receives the signal from the drawer is driven to rotate the arm 28 via the reduction gear 30 row. Thus, the guide shaft 21 connected to the arm 28 is eccentrically rotated. Therefore, driving the motor 32 to raise the guide shaft 21 to the upper, guide wheels 22 and 23 are inserted into the through groove 24 of the tripping guide 20 to derive the upper portion of the guide wheel. .

At this time, the motor 32 stops driving, and the guide shaft 21 itself is configured to rotate, so when the lower part of the coil falling on the guide wheel 22 is caught, the coil rotates naturally and the roller Will be sent. Further, power is transmitted to the sprocket 42 formed at the extended end of the guide shaft 21 by using the chain drive by the chain 44 due to the driving of the roller 40, thereby transmitting the rotational force, whereby the guide shaft 21 will rotate. The chain 44 is always kept in tension through the spacing sprocket 46 and the tension spring 50 attached thereto.

Coil 100 falling from the winder (3) is the end of the rolled material is not bitten by the drawer, so the propulsion force is reduced by not being pushed out of the drawer, and the coil is affected to a certain degree by cold rolling Although the phenomenon of floating in the air, according to the apparatus of the present invention, the lower portion of the coil 100 is caught in the groove formed in the guide wheels 22 and 23, even if the guide wheels 22 and 23 rotate, The dropping speed of the upper part is faster, and it is laid down on the conveyor roller due to the speed difference between the lower part and the upper part of the coil. This is as shown in FIG. 6, where the difference between the speeds V1 and V2 causes the coil to lay on the top of the roller. At this time, the rotation of the guide wheel is to maintain the shape of the coil so that the coil is pushed out at the same time lying down.

Again, when the drop of the coil is completed, the motor 32 is driven in the opposite direction, which is configured to drive after a predetermined time by a sensor (not shown) inside the winder or by a timing means. . While the motor 32 is driven in the opposite direction, the guide shaft 21 slowly rotates in the opposite direction via the row of the reduction gear 30 again, and stops when the predetermined position is reached.

In addition, when the rear end of the coil due to the low temperature winding is moved by the feed rollers through the above process, the cylinder 64 is pulled so that the pressing roller 60 held down according to the signal of the extractor comes down. The cylinder 64 pulls the arm 62, whereby the pressing rollers 60 inserted into the upper part of the arm to be rotatable rotate while contacting the upper part of the coil, and the rear end coil is already formed and moved. After pressing in the same manner as the stacking density of the coil of the front part is moved back to the upper side.

As described above, according to the present invention, since the irregular arrangement of the rear end portion of the coil through low temperature rolling is placed on the conveyor roller by adjusting the falling direction of the falling coil, it is safely transported without abnormality on the conveyor, and no separate manual work and correction work are necessary. It is effective.

In addition, according to the present invention, the secondary compression process is automatically performed, the entire coil is laminated with a uniform density, and the advantageous effect of preventing from being caught on the mandrel in the final winding process of the coil, to prevent the interruption of the work It is.
