Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a position detection device for a strip coil binding band, and is capable of accurately detecting the position even when the binding positions of the bands are different.

[Conventional technology]

Generally, when a hot-rolled strip coil is carried into a pickling line, a step is required to remove the bands of the strip coil bound together on the entry side of the metal strip processing line. The process of removing this band is
Although this is performed by a band processing device, the operation of aligning the band processing section to the band binding position is not always the same, so the operator visually determines the band position. After recognition, manual operation is performed.

[Problem that the invention seeks to solve]

Examples of cases in which the binding position of the band with respect to the strip coil is uneven and inconsistent include cases where the band breaks during handling and the hand band is re-tied, or where the band has loosened and is hung diagonally. In some cases, the banding position deviates from the normal binding position, or in cases where the banding position and number of bands differ for each upstream line, such as in a conveyor line that receives strip coils from multiple upstream lines. There are cases where the band position cannot be determined.

As mentioned above, since the band positions of the strip coils are not the same, it is said that complete automation of the band removal process using the band processing device is difficult.

However, in recent strip coil processing lines, it is required to achieve a higher level of automation and labor saving in each processing process, and in the band processing process, band positioning operations of band processing equipment are required. There is a strong demand for the development of a band position detection device necessary for automation.

This invention was made in response to the above-mentioned needs, and is a device that can accurately detect the band position even when the band binding position differs for each strip coil, and is capable of completely automating the band removal process. The purpose is to provide a device that contributes.

[Means for solving problems]

The position detecting device for a strip coil binding band of the present invention comprises a base installed at a position that does not interfere with the strip coil on the side of a co-coil holder on which a strip coil with a band bound on the outer peripheral surface is placed, and a base mounted on the base. a coil detection cart that reciprocates in a manner that allows the coil to move toward and away from the outer circumferential surface of the strip coil; It is equipped with a horizontal mount that is pivotally attached to the coil detection cart, and a band detection cart that reciprocates on the horizontal mount in parallel to the width direction of the strip coil. The horizontal mount is provided with contact portions at two locations in the width direction of the strip coil to contact the outer peripheral surface of the strip coil to determine the attitude of the horizontal mount, and the band detection cart is equipped with contact portions at two locations in the width direction of the strip coil. It is equipped with a band detector that detects the band binding position and a movement amount detector that detects the amount of movement of the band detection cart at the band binding position detected by the band detector.

[Effect]

The coil detection cart moves forward toward the strip coil placed on the coil holder, and stops when the coil detector detects contact with the outer peripheral surface of the strip coil.

At this time, two contact portions of the horizontal mount come into contact with the outer peripheral surface of the strip coil to determine the attitude of the horizontal mount with respect to the strip coil, making it parallel to the axial direction of the strip coil. Here, when the extending direction of the horizontal frame is not oriented in the axial direction, one of the contact portions first contacts the strip coil due to the forward movement of the coil detection cart, and the horizontal frame turns due to the reaction force against this contact. Then, the other contact portion also contacts the strip coil. Therefore, the horizontal frame is forced to be parallel to the axial direction of the strip coil.

Therefore, the band detection cart always moves parallel to the width direction of the strip coil, and the band detector detects the band of the strip coil. The movement amount detector of the band detection cart detects the movement amount of the band detection cart from the movement start position to the movement end position, and
The position of the band is detected based on this amount of movement.

〔Example〕

FIG. 1 is a side view showing an embodiment of the invention.

In the figure, reference numeral 2 indicates a coil pedestal installed on a coil conveyance line, and reference numeral 3 indicates a walking beam. A strip coil 5 (5a is a large diameter coil, 5b is a small diameter coil) is carried by a walking beam 3 and placed on a coil holder 2.

A band processing device (not shown) is installed downstream of the coil conveyance line, and a band (not shown) binding the outer peripheral surface of the strip coil 5 is installed.
is removed by a band processing device.

The band position detecting device 10 of the present invention is placed on the side of the coil holder 2 on which the strip coil 5 is placed.

The base 11 of the band position detection device is installed in a position that does not interfere with the strip coil 5 placed on the coil holder 2, and if the strip coils 5 are not of the same diameter, the base 11 is set with the large diameter coil 5a as a reference. It is desirable to select a position as close to the outer periphery of the coil as possible and that does not interfere with the coil conveyance.

This base 11 is framed in the shape of a right triangle, and its length direction (direction perpendicular to the plane of the paper) is arranged parallel to the length direction of the coil holder 2, with the sloped side facing the coil holder 2. It is directed towards.

A coil detection cart 15 is mounted on the diagonal member 12 of the base 11 via guide rollers 16 on a guide rail 14 laid in the direction of inclination of the slope. Frames 16 and 17 that protrude diagonally forward are attached to this coil detection truck 15, and connect the piston rod 19 and cylinder tube 20 of the hydraulic cylinder 18 to the lower frame 17 of the coil detection truck 15 and the base 11, respectively. It is fixed to the blanket 13 at the upper end of the diagonal member 12. When this hydraulic cylinder 18 is actuated, the coil detection cart 15 is reciprocated in the direction of inclination of the slope of the base 11 while being guided by the guide rail 14.

Upper frame 16 of the above coil detection cart 15
A horizontal frame 22 is rotatably installed at the tip of the frame 22 via a pin 23 . A coil detector 25 is attached to the front surface of the horizontal mount 22, and two coil touch pieces 26 are attached on both left and right sides to form contact portions that contact the outer peripheral surface of the strip coil. In addition, on the upper surface of the horizontal frame 22,
A band detection cart 30 equipped with a band detector, for example a shock sensor 31, is mounted thereon.

As shown in a plan view in FIG. 2, the band detection cart 30 described above is mounted on a guide rail 27 laid in the length direction of the horizontal mount 22 via a guide roller (not shown). Further, a brake motor 33 is mounted on the guide rail 27, and the band detection cart 30 is moved back and forth on the guide rail 27 by the brake motor 33.

The band detection cart 30 and the brake motor 33 are integrally connected by a connecting plate 41 between the pulse generator 40 directly connected to the rotating shaft 34 of the brake motor 33 and the band detection cart 30. A pinion 35 fixed to a rotating shaft 34 of the rack 33 is meshed with a rack 36 fixed in the longitudinal direction on the horizontal frame 22.

The above pulse generator 40 is connected to the brake motor 3
3 is driven to rotate, the distance traveled via the pinion 35 that engages with the rack 36 and rotates, that is, the horizontal mount 22 of the band detection cart 30.
The number of pulses corresponding to the amount of movement in the length direction is generated.

Next, the operation of the band position detection device having the above configuration will be explained.

The strip coil 5 conveyed by the walking beam 3 is placed on the coil holder 2,
When the walking beam 3 descends, a detector (not shown) detects the lower limit position of the walking beam 3. Further, when the strip coil 5 is placed on the coil holder 2, the coil seating detector 7 detects that the strip coil 5 is stopped at a fixed position. When both of these detection signals are sent out at the same time, an activation command is issued to the band position detection device 10.

Based on this start command, first hydraulic cylinder 1
8 is activated and the piston rod 19 is extended. As a result, the coil detection cart 15 moves from the upper end position of the base 11 onto the guide rail 14 to strip the coil 5.
descends toward the outer circumferential surface of the

When the upper frame 16 of the coil detection cart 15 approaches the strip coil 5 and the coil detection cart 25 of the horizontal mount 22 contacts the outer peripheral surface of the strip coil 5 to detect the strip coil 5, this detection signal causes the hydraulic cylinder 18 to operate. pause,
This causes the coil detection cart 15 to stop at the lower end position.

The horizontal frame 22 at the lower end position of the coil detection cart 15 is connected to the upper frame 16 of the coil detection cart 15.
Since the strip coil 5 is rotatably installed through the pin 23, even if the longitudinal center line of the strip coil 5 placed on the coil holder 2 is deviated from the longitudinal direction of the coil holder 2, , horizontal frame 22 is pin 2
3 to position the two front coil touch pieces 26 in contact with the outer peripheral surface of the strip coil 5. Therefore, horizontal frame 2
Even if there is a deviation in the mounting direction of the strip coil 5, the length direction of the strip coil 5 is maintained parallel to the width direction of the outer peripheral surface of the strip coil 5.

Next, the brake motor 33 is rotationally driven,
A pinion 35 fixed to a rotating shaft 34 of a brake motor 33 meshes with a rack 36 and rotates.
As a result, the band detection cart 30 integrally connected to the brake motor 33 moves from one end position of the horizontal frame 22 to the other end position on the guide rail 27 in the width direction of the strip coil 5. Move horizontally.

While the band detection cart 30 is moving between both ends of the horizontal frame 22, the band bound to the outer peripheral surface of the strip coil 5 is detected by the shock sensor 31.

The amount of movement of the band detection cart 30 is converted into the number of pulses generated by a pulse generator 40 and monitored.
The number of pulses when the band binding position is detected is stored in the storage means. This number of pulses is transmitted as information indicating the band binding position to the band processing device via the information transmission means when the strip coil 5 is conveyed to the band processing device on the downstream side.

After the position of the strip coil 5 has been detected as described above, the band detection cart 30 is moved to the original position of the horizontal mount 22, and the coil detection cart 15 is moved to the base 11.
Each strip coil returns to its original position and waits until the next strip coil is placed on the coil holder 2.

As the band detector in the above embodiment, a distance meter may be used instead of the shock sensor.

In addition, in the above embodiment, a case was explained in which the band detection cart is mounted on a horizontal mount that can rotate freely on the coil detection cart, but this horizontal mount can be omitted and the band detection cart is mounted directly on the coil detection cart. It may be placed on a shelf.

〔Effect of the invention〕

As explained above, according to the present invention, the coil detection cart moves forward toward the strip coil, and the two contact parts of the horizontal mount come into contact with the outer peripheral surface of the strip coil, so that the horizontal mount is forced to move toward the strip coil axis. Since it is parallel to the direction, it may be difficult to use when the strip coil band is not in the normal binding position,
Not only is it now possible to accurately detect the band position even when the diameters of the strip coils are different, but even if the axial direction of the strip coil deviates from the predetermined direction, the horizontal mount can be forcibly detected as described above. The position of the band can be reliably detected because the band detector is moved parallel to the axial direction of the strip coil on the outer circumferential surface of the strip coil. can do.

Therefore, if the detection device of the present invention is used in combination with a band processing device, the band positioning operation of the band processing device can be automated, which has the effect of increasing the reliability of the band processing work.
