Description

Coil bore end labeling system {SYSTEM FOR ADHERING A LABEL ON THE END OF INNER COIL}

The present invention relates to a coil bore end labeling system, and more particularly, to a coil bore that accurately detects the bore end of a coil end product produced in a hot rolling mill correction line and attaches a predetermined position label from the detected end. An end labeling system.

In general, the equipment configuration of the hot rolled winding machine of the hot rolling mill is controlled by the roll-out of the last stand of the rolling mill to control the winding temperature through a runout table, and then the strip passes between the pinch rolls and the strip on the mandrel of the winder This will be wound up. Two winding apparatuses as described above are usually provided. The winding control on the end of the strip has a great influence on the winding shape of the coil and the quality of the coil. The strip passed through the heating furnace as described above is extruded from the finishing mill, and then completed by a coil of a constant volume coil. For the final product of the coil, the product is completed by labeling the inner diameter end of the coil.

As described above, accurately recognizing the position of the inner end of the coil inner part to be labeled and attaching the label accurately and promptly is an important part in the final product management. Therefore, the coil inner diameter is conventionally used by using an image camera and a roller type sensor. The end of has been detected and labeled. The above-described conventional apparatus and method will be briefly described.

Figure 1 schematically shows a conventional coil bore end detection device. Referring to FIG. 1, the image camera 120 installed in the head unit 110 of the automatic label attacher 100 detects the yin and yang of the coil inner diameter end portion 130 to detect the coil inner diameter end portion 130. In the above method, if grease or other foreign material is applied to the inner diameter of the coil, the image camera incorrectly recognizes the detection time and takes a lot of time. The error rate was reduced by removing a label attached to another position from the end portion 130 or scraping the labeling position, and thus, a corrector often reissued the label and manually attached the label to the coil end by hand.

2 is a view illustrating another form of the conventional coil bore end automatic detection device. Referring to FIG. 2, unlike the detection method of the image camera 120, the head portion 210 of the automatic label attaching device 200 is shown. In the installed al-bending floating apparatus 220, the touch cylinder roller 240 enters the coil inner diameter and contacts the coil inner diameter surface in order to detect the coil inner diameter end portion 230. The touch cylinder roller 240 rotates the surface of the coil inner diameter end portion 230 and detects the protruding portion of the final end portion of the coil inner diameter end portion and detects it with the sensor 250. However, when the protruding portion is located at a long distance from the rotation start direction of the al-bending floating apparatus 220, it takes a long time to detect and rotate the al-bending floating apparatus 220 when the inner diameter surface is bent or the coil center does not fit. ) Has malfunctioned and could not be attached correctly to the labeling position.

Therefore, in the conventional method as described above, the position of the end portion of the inner diameter of the coil to which the label is attached was not accurately detected, and thus the labeling was not accurate, so that the manual work was often performed. There was a problem such as falling.

The present invention has been made in order to solve the above problems, an object of the present invention is to accurately detect the position of the product label attached to the end of the inner diameter of the wound coil final product. It is further an object to provide a system for automatically attaching a label to the detected position.

The present invention as a constituent means for achieving the above object, in the coil inner diameter end labeling system in the correction line of the hot rolling mill to produce a coil product by winding the coil using a tension reel,

A tension gripper which fixes the end by inserting the end of the coil inner diameter into the tension reel;

A gripper strike coupled to one surface of the tension reel to show the same position as the tension gripper,

A plurality of position detection sensors detecting a position of the gripper strike;

A control unit for recognizing data on the position of the detected gripper strike and designating a position to which a label is attached; and

And a label auto-attachment device controlled by the control unit and automatically attaching a label according to the designated position.

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

3 is a block diagram of the coil bore end detection device according to the present invention. As shown in FIG. 3, the final product of the coil 7 wound around the tension reel 5 is wound, and the inner diameter end 6 of the coil 7 is a tension gripper 4 of the tension reel 5. And a gripper strike (3) attached to the same position as the tension gripper (4) for introducing the inner diameter end portion (6) of the coil to one side of the tension reel (5), and the gripper strike ( 3) detects and recognizes the position of the watch-shaped segment block 1 having twelve position detection sensors 2 and the position of the gripper strike 3 detected by the position detection sensor 2; The control unit 8 controls the overall operation of the system and at the same time, the control unit 8 for processing and transmitting data through a predetermined program, and the label automatic for attaching a label to the end of the coil bore using the data output from the control unit 8. The attaching machine 9 is provided.

The gripper strike 3 is coupled to one end of the tension gripper 4 by a fastening bolt, and the position of the gripper strike 3 is installed in the same direction as the tension gripper 4. In addition, after the tension reel gripper 4 is reduced, the end 6 of the coil 7 is retracted and enlarged again to wind the coil in a state where the drawn end 6 is firmly fixed. The coil 7 is wound while rotating at a high speed with respect to the central axis 10 of (5). Accordingly, the drawn inside diameter end 6 of the coil is always the same as the position of the tension gripper 4 and the gripper strike 3 with respect to the central axis 10 of the tension reel 5. In other words, the position of the end portion 6 of the coil bore is the same as the position of the gripper strike 3, and finally, the position of the end 6 of the coil bore 6 is determined by grasping the position of the gripper strike 3. I can figure it out.

When the winding of the coil 7 is completed, the coil is withdrawn and reaches a basis weight (not shown) to end the basis weight. Accordingly, the tension gripper 4 is again reduced and the coil inner diameter end portion 6 drawn out is drawn out of the tension gripper 4.

Meanwhile, at the rear end of the gripper strike 3, a segment block 1 having twelve position detection sensors 2 is located. Here, the number of the sensors 2 is not limited to 12 and the number may be changed. It is obvious that more will detect the position more precisely, and smaller will detect the location less precisely. The sensor 2 detects the position of the gripper strike 3. The position data value of the gripper strike 3 detected as described above is transmitted to the controller 8. The control unit 8 controls the label automatic attaching machine 9 by processing the data value through a predetermined program. The label automatic attaching machine 9 attaches a label to a predetermined position corresponding to the detected position data value.

Here, the control unit 8 is composed of a programmable logic controller (PLC) and / or small computers to execute a series of processes according to a program already set in advance, whereby the position detection sensor 2 detects the position. And process the received position data and control the operation of the label automatic attaching machine 9 by the set program. In addition, the label automatic attaching machine 9 is designed to grasp the position where the label is attached according to the control instruction of the controller 8 and to automatically attach the label to the position.

Therefore, the position of the end portion 6 of the inner diameter of the coil is determined by the position of the gripper strike 3, and the gripper strike 3 is detected by the position detection sensor 2 to control the detected position data. (8) is received and transmitted to the label automatic attaching machine (9) to control it. In this way, the label automatic attaching machine 9 automatically recognizes the end 6 of the coil bore detected in the process and automatically attaches the label to the recognized position. The detection position at which the label is attached may vary depending on the control amount of the controller 8. That is, the detected position may be the end 6 of the coil bore or the position of the label to be attached may be a certain distance away from the end 6. In the present invention, the coil inner diameter is controlled to attach the label to the inner end of the end 6 in 100mm, but is not limited to this, the desired position can be changed in various ways.

4 is a detailed view of labeling after detecting the coil bore end according to an embodiment of the present invention to briefly show a situation in which a label is attached using a label auto-adhesive device by detecting the position of the gripper strike. Figure 4 (a) shows that the sensor detects the gripper strike according to the present invention and Figure 4 (b) shows that the label auto-adhesive affixes the label using the position (direction) of the detected gripper strike. More specifically, in FIG. 4 (a), the gripper strike 3 attached to one end of the tension reel 5 is detected by the sensor 2 at the 7 o'clock position among the 12 position detection sensors 2. It shows. The tension reel 5 rotates at high speed with the coil and stops rotation when the winding ends, and when the rotation stops, the position (direction) of the gripper strike 3 attached to one end of the tension reel 5 is stopped. The rear position detection sensor detects it. In the above example, the sensor 2 at 7 o'clock detects this and transmits the detected data to a controller (not shown).

In FIG. 4 (b), the label automatic attaching machine 9 recognizes the end 6 of the coil bore at a position corresponding to the detected data value, i.e., the 7 o'clock, by the control amount of the controller, and the end The label 11 is attached to the predetermined position d from (6). 4 (a) and 4 (b) are electrically or physically connected as described above, but the drawings are omitted here.

5 is a flowchart showing the process of detecting the inner diameter of the coil and labeling process according to the present invention, wherein the end of the coil is inserted into the tension gripper attached to the tension reel to wind the coil and detect the position of the inner diameter of the wound coil. And the process of applying a label using the detected position is shown.

First, the end 6 of the coil is introduced into the tension gripper 4 (S501). The tension reel 5 is enlarged to fix the end 6 of the coil, and then the coil is wound (S502). When the winding of the coil is completed, the tension reel 5 that is enlarged is reduced and the end 6 of the coil inner diameter drawn out is drawn out (S503). The position of the gripper strike 3 coupled to one side of the tension gripper 4 is detected by the position detection sensor 2 (S504). The detected position is received by the controller 8 to detect and recognize the coil bore end 6 (S505). The data on the desired position is transmitted from the recognized coil inner diameter end 6 to the label automatic attaching machine 9 (S506). The label automatic attaching machine 9 receives the data and attaches a label to a position corresponding to the data (S507).

As described above, the label automatic attaching machine 9 is operated and controlled by the control unit 8 and attaches a label according to the position transmitted from the control unit 8.

The above description and drawings disclose one embodiment according to the present invention, but may be variously manufactured without departing from the spirit of the present invention. Therefore, the scope of the present invention should be determined by the appended claims rather than by the foregoing description.

As described above, according to the coil bore end labeling system of the present invention, it is possible to accurately detect the bore end of the wound coil and thus to accurately label the desired position from the end so as to attach the label. Furthermore, the production efficiency is increased by preventing the increase of manual labor due to label position failure.
