Description

Strip Sample Induction Device {APPARATUS FOR GUIDING STRIP SAMPLE}

The present invention relates to a device for collecting and guiding strip samples for material testing in order to confirm that the production product is manufactured to a quality level that meets the needs of customers in the final production process of strip (steel sheet) of steel mills, more specifically cutting Samples sheared and dropped at a constant rate from the device are automatically guided without any damage (deformation or sample change) and stop of the production process, automatically center the guided samples, and the sample labeling and sample work process after sampling The present invention relates to an improved strip sample induction device to improve work productivity by preventing failure of the drawing process.

In general, the strip sample guide device according to the prior art, as shown in FIG. 1, when shearing the strip (S) proceeds to the cutting device 300 to take the sample (P), the cutting device 300 The strip sample (or scrap) P sheared by the drop is dropped to the sample guide chute 310 through the fixed guide table 301 while maintaining the traveling speed of the strip S. In this process, the sample S is rubbed on the inclined portion of the chute 310, and the neat state during shearing is disturbed.

In addition, the falling sample is guided to the sample box 320 after passing through the chute 310 at a constant speed and finally hit the wall of the sample box 320 and stops. At this time, the strip sample (P) before the stop, when the collision with the sample box 320 occurs, such as bending corners, the reaction occurs by the reaction to the bounce phenomenon occurs, thereby causing the position of the sample sample box 320 Outside the center of the

As described above, the failure of the position of the sample in the sample guide chute 310 to maintain the shear state is due to the difference in the width level of the chute 310 and the inclination of the chute during the drop of the sample S, The contact is not made at the same time, the strip sample (P) is difficult to maintain the shear state due to various factors, such as the difference in roughness (roughness) of the chute surface made of steel sheet and the resistance element of the air.

This sample is then transferred to a subsequent label applicator.

On the other hand, there is another conventional technique as shown in Figure 2, there is a sample centering device on the chute, which has caused frequent failures because the sample falls at a constant speed, which is sheared in the cutting device 300 While the sample is dropped at a constant speed, the edges of the strip sample are interfered with the variable width guides 353 and 354 of the sample centering device installed in the induction chute 310, thereby causing the strip sample P to stagnate on the chute. The tip end again interferes with the stagnant sample, causing disruption to the production process.

Thus, as a problem of the prior art as shown in the first and second, as shown in the first and second, the strip sample is caught in the chute 310, stagnation, corner bending, etc., and reaches the sample box 320 to normal When one sample collides due to the dropping speed, corner bending and deviating from the center loading position occur. As a result, after the sample box 320 reaches the labeling position on the traveling rail 355, the labeling machine 360 When the label is attached on the strip sample, the sample position is bad, and there is a case where there is no sample at the label application position or the label is attached to the scrap which is not the sample.

In addition, the accurate strip sample P cannot be adsorbed from the vacuum suction pad 371 type sample gripper 370 in the subsequent process of taking out and collecting the sample and scrap, causing manual operation by the operator as a result of failure. As a result, the automatic processing device of the sample P cannot be in a normal operating state, and the manual work causes a workload in the production process, and a defective product of the normal product due to a defective strip sample (shape damage and change of the sample and scrap). Judgment has arisen and it has caused various problems that caused dissatisfaction of the demand price such as delay in delivery of the product.

The present invention is to solve the above conventional problems, the purpose is to take the sample for material test in the final production process of the steel sheet to lead to the test chamber, the damage of the sample, the sample jam (retention) It is possible to improve the productivity of the process and to make accurate quality judgments and to prevent the safety accidents on the job site by automatically eliminating the production failures and the problem of changing the strip samples and scraps. It is to provide an improved strip sample guide device.

By driving each power source is to be electrically connected to each drive element to achieve automatic operation.

Referring to the operation and effects of the present invention configured as described above are as follows.

As shown in FIG. 3, the strip sample guide device 1 according to the present invention is automatically controlled when the welding portion of the strip S reaches a certain distance in front of the cutting device 300.

That is, the cutting device 300 is decelerated for the sample shear preparation work before and after the welding portion of the strip (S) is decelerated to a set speed of 30 ~ 50MPM and at the same time the equipment control computer 100 instructs the preparation of the sample guide do.

To this end, the strip sample guide device 1 according to the present invention has the support plate 12 of the sample gate 10 lowered by the operation of the pneumatic cylinders 14a and 14b to maintain the same level in the width direction. The proximity limit sensor 16b detects. Further, down to the support plate 12 of the sample gate 10, the cut strip sample P does not travel in the direction of the strip traveling conveyor 200 shown by the dotted line in FIG. The magnet conveyor belt unit 30 is prepared in a state capable of being guided through, and the magnet conveyor belt unit 30 is also instructed by the facility control computer 100 to drive the motor 36 and rotate the conveyor belt 32. The speed is counted by Peg 38.

In addition, power is also supplied to the electromagnet 34 for the magnet conveyor and maintained at a constant magnetic force. The sample box 79 is inclined around the rotating shaft 94 by an up operation of the cylinder 90. Tilting (tilting), wherein the base plate 80 level of the sample box 79 is kept somewhat lower than the exit level of the magnet conveyor belt portion 30, the inclination is of a gentle slope than the conveyor belt portion 30 The rising position of the sample box 79 is detected by the proximity limit sensor 102a.

With the preparation operation as described above, the facility control computer 100 checks the open (OPEN) position of the sample centering guide bar 74 with the signal of the sensor 130, and if not the open position, the centering guide bar 74. ), And the preparation completion signal is input to the facility control computer 100 when the shear preparation is completed by the above operation.

Thereafter, when the cutting device 300 continuously shears the strip sample P or the scraps directed to the facility control computer 100 at 30-50 MPM, the sample P has a strip speed that has been progressed before the shear and is constant. It must be guided and discharged so that no interference due to interference with trailing samples occurs.

Therefore, when the sample is cut to a certain length in the cutting device 300, the sample is directly guided to the sample gate 10 at the speed of the progress, the roller 24 of the sample gate 10 is the minimum sheared sample In order to proceed with friction, the occurrence of poor centering of the sample due to the friction is suppressed, and the sample passing through the sample gate 10 is guided to the magnet conveyor belt portion 30 which is driven slightly faster than the speed of the process.

In addition, the strip sample P passes through the cutting device 200 at its shear rate, its own weight, and passes through the roller table 301 and the sample gate 10. The magnet conveyor belt unit 30 is considered in consideration of the passing speed of the sample. Speed is controlled by the equipment control computer 100 a little faster + 20mpm, the belt 32 is a rubber belt surface is processed with a fine groove (GROOVE) on the surface so that the strip sample slips on the belt portion 30 Or bad centering.

In addition, the magnetic force of the electromagnet 34 located inside the belt 32 is controlled so that the sample P is not separated from the belt 32.

And, through the magnet belt conveyor according to the present invention, the sample (P) is not bent at the edges, corners, etc., it is possible to prevent the conventional problems such as sample jamming, congestion, strip leading end failure of the sample gate 10 position. And the sample passing through the magnet belt conveyor is led to the sample box 79 with the cylinder 90 standing up.

In addition, the magnet conveyor belt unit 30 is a cutting device 300 is a shear amount of the sample or scrap by the amount set by the control computer 100 of the process after the front end of the strip (S) is the sample gate 10 is raised When the strip progress conveyor 200 passes a predetermined length in the state, the facility control computer 100 receives the detection signal from the photo sensor 210 to stop the motor 36 of the magnet conveyor belt unit 30 and stop the electromagnet. The power of 34 is turned OFF, which means that all the sheared samples are completely led to the sample box 79. On the other hand, the photo sensor (76a) (76b) mounted on the conveyor belt portion 30 side direction in the base plate 80 of the sample box 79, the strip sample (P) is the sample box in the conveyor belt portion 30 Upon induction to 79, the strip sample is detected and the facility control computer 100 receives the electrical signals from the sensors 76a and 76b to count the number of samples.

In addition, if the count value does not match the number of shear sheets, since the strip sample is not guided to the sample box 79, the facility control computer 100 generates an alarm sound by operating an alarm device (not shown) to the driver. If the number of samples continuously sheared by the shearing apparatus 300 and the number counted by the detection of the sensors 76a and 76b are the same, the sample box 79 is leveled by the lowering execution of the pneumatic cylinder 90, and the horizontal When the state is detected by the proximity limit sensor 102b, an automatic centering operation of the strip sample is executed.

To this end, the facility control computer 100 closes the centering guide bar 72 according to the operation of the motor 112 and the rotation of the ball screw shaft 116 based on the material data of the sheared sample P. Control by counting the number of revolutions of the peg 114 installed.

This is because the centering guide bar 72 is moved from the bottom of the base plate 80 to the center of the base plate 80 by the operation of the motor 112, in this process, mounted on the upper side of the guide bar 72 The touch bar 133 passes through the grooves 82 of the base plate 80 to push both edges of the strip samples deposited on the base plate 80 to align the center of the base plate 80.

The strip sample (P) aligned in the correct position through this process is applied to the labeling machine after the sample car 74 has reached the labeling position in the conventional way on the driving rail 355 by the control of the facility control computer 100 360 attaches the label to the strip sample.

Therefore, according to the present invention as described above, during the sampling operation of the sample for the material test, the problem of damage to the sample (knock, change, etc.) does not occur, and congestion does not occur during the dropping of the sample, thereby preventing production of the strip manufacturing process. Does not generate

In addition, the automatic centering of the sample is possible, so there is no obstacle in labeling, sample withdrawal, and collection after sample collection, so that automated work is possible, thus reducing the workload, improving productivity, and preventing safety accidents. This results in improved effects such as accurate material testing.
