BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a length measuring / cutting method and a steel length measuring / cutting equipment using the method. More specifically, the present invention relates to a method for improving the length measuring accuracy of a laminated steel material and measuring a steel material.

2. Description of the Related Art Rolled steel products are cut into final product dimensions by a steel length measuring and cutting facility before being shipped. In conventional steel length measuring and cutting equipment, an operator measures the length of steel by a tape measure and marks the cutting position on the loading side table, and then transports it to a cutting device by a roller conveyor and cuts it according to the marking. Thereafter, the sheet is again carried out to the carry-out side table by the roller conveyor.

[0003]

However, in the conventional steel material measuring and cutting equipment, the length measuring and cutting of such steel materials can be performed.
Since the marking relied only on manual work by the operator, the work efficiency was poor, and the dimensional accuracy of the cut steel material also varied. Therefore, it is conceivable that the position of both ends of the steel material is automatically detected by a position sensor by a length measuring device and the length of the steel material is measured from the detected value.
As described above, when the end face of the steel material is automatically detected by the position sensor, when a plurality of steel materials are cut at one time, if the end face positions of the respective steel materials are not exactly aligned, a positional deviation from the actual steel material dimension is obtained. Because of the long misinterpretation, there is a concern that the dimensions of similarly cut steel materials may vary. In addition, the transfer table that automatically sends the steel material onto the roller conveyor is located on the carry-in side table, which is the work site for measuring and marking steel materials, and there are obstacles to work such as protrusions and gaps on this table. And there was a problem with work safety. The present invention has been made in view of such circumstances, and it is possible to improve the accuracy of measuring the length of a steel material in a laminated state, and to perform a remote operation of a consistent steel measuring and cutting operation from measuring the length of the steel material to cutting. Length measuring / cutting method that can also achieve work safety and steel length measuring / cutting method using the method
The purpose is to provide cutting equipment.

[0004]

According to the present invention, there is provided a semiconductor device comprising:
In the length measuring / cutting method described above, the irregular tip surfaces of a plurality of overlapped measured objects conveyed downstream are aligned by an alignment stopper, and a length measuring cart having length measuring means is arranged in parallel with the measured object. The measured object is moved to the rear end position along the guide rail, and the image of the measured position of the measured object is input by a camera provided on the length measuring cart, and is visually measured on a monitor screen having a base line. After aligning the measurement position of the object to be measured with the baseline and measuring the length of the object to be measured based on the output value of the length measuring means, the cutting device installed on the upstream side is used to measure the length of the object. In order to cut the measured object at a predetermined position, the length measuring cart is moved upstream to a predetermined position based on the measured length of the measured object and a cutting position by the cutting device, and the predetermined At the rear end of the DUT There the workpiece conveyed on the upstream side so as to coincide, after clamping the 該被 measured and cut. According to a second aspect of the present invention, there is provided a steel material length measuring / cutting device which is provided with a length measuring means, a clamper, and a cutting device provided in the middle of a transport device capable of transporting a plurality of overlapped, measured objects having irregular tip surfaces. A steel length measuring and cutting equipment for cutting an object to be measured to a predetermined size, comprising, at a downstream end of the transfer device, an alignment stopper capable of aligning the irregular tip surfaces, and a guide rail along the transfer device. And a length measuring cart having on the guide rail a length measuring means for measuring the measured object and a camera for inputting an image of the measured position of the measured object, and a base line is drawn on a monitor screen for displaying the camera image. A monitor is provided so that the transport direction of the transport device can be reversed.

[0005]

In the length measuring / cutting method according to the first and second aspects and the steel length measuring / cutting equipment using the method, the length measuring cart having the length measuring means for the measured object is arranged in parallel with the measured object. The measurement position is measured along the guide rail, and the image of the measurement position of the object to be measured is input by a camera provided on the length measurement cart. The input image is displayed on the monitor screen, and the measuring position of the DUT is aligned with the base line of the monitor screen by visual measurement while slightly moving the length measuring cart. Even if the length is longer, the length measurement accuracy on the monitor screen can be arbitrarily improved at the discretion of the measurer. Thereafter, since the length of the object to be measured is measured based on the output value of the length measuring means, the remote operation of the steel material cutting work from the length measurement to the cutting of the steel material can be performed.
Moreover, in the past, it was dangerous for the operator to perform length measurement and marking of the cutting position of the steel material on the carry-in side table, which is the range of movement of the steel material feeding device, but this method allows remote operation in this way. Safety can be improved.

Next, a method of measuring and cutting the steel material 13 according to one embodiment of the present invention using the steel material measuring and cutting equipment 10 and a steel material measuring and cutting operation using the same will be described. As shown in FIG. 1, the steel material 13 placed on the carry-in side table 11 is sent out onto the roller conveyor 14 by the transfer 18A every two hills.
Is conveyed to the unloading table 12 side. The transported steel material 13 collides with the alignment stopper 27, and the irregular tip surface of the steel material 13 is aligned with the side surface of the alignment stopper 27 in a line. The state is confirmed by the fixed camera 30. At this time, if the tip end surface of the steel material 13 remains irregular or if the steel material 13 is separated from the alignment stopper 27, the roller conveyor 14 is rotated in the reverse direction and the steel material 13 is once pulled back, and then the alignment stopper is again moved. Collision with 27 to realign. In addition, the steel material collision surface of the alignment stopper 27 is set as the origin O at the time of steel material length measurement.

Then, according to the shape of the steel material 13, the camera 23 is moved to a position where the end face of all the steel materials 13 on one mountain can be confirmed.
Is moved (diagonally above the steel material 13 on one side because the steel material is of the SPL type in the embodiment).
Is performed by moving the Y and Z sliders 34 and 36 by the Y and Z motors 38 and 39. Then, the length measuring cart 21 is moved along the guide rail 20 by the drive motor 22 to the rear end face position of the steel material 13. This situation is displayed on the monitor 2 of the control room 17 as an image of the camera 23.
6 is displayed on the monitor screen 24, the length of the steel material 13 on one side is determined by adjusting the position of the rear end face of the steel material 13 to the base line 25 with reference to the origin O, and the encoder detects the rotation speed of the drive motor 22 at this time. Is calculated by the control panel 40 based on the detected value. The length of the steel 13 is displayed on the first display section 44 below the monitor 26, and the length of the steel 13
The length of the intermediate position (cutting position) obtained by bisecting the length is displayed on the second display section 45 below the display section 44.

Since the position of the rear end face of the steel material 13 on one side is aligned with the baseline 25 by the measurement of the measurer in the control room 17, the position of the rear end face is somewhat irregular as shown by the chain line in FIG. Even when the length of the laminated steel 13 is measured, it can be arbitrarily corrected on the monitor screen 24 by, for example, adjusting the rear end position to the shortest steel 13 at the discretion of the measurer. That is, if the position of the rear end face of the steel material 13 is detected by completely automatic control, the length of the steel material 13 is erroneously measured longer by the positional deviation than the actual length at the time of length measurement, and should be bisected. While the shortest steel material 13 may have an extremely large dimensional error after cutting, the present method can intervene by the measurement by the measurer including the working experience as described above, and the dimensional variation of the steel material 13 after cutting can be interposed. Can be suppressed as much as possible. When the length measurement of the steel material 13 on one side is completed in this way, the camera 23 is moved obliquely above the steel material 13 on the other side, and the same operation is performed.
Measure 3

Thereafter, the intermediate stopper 28 is lowered onto the roller conveyor 14, and then the conveyor 14 is rotated in the reverse direction to move the steel material 13 whose length has been measured to the carry-in side table 11 side. Actually, the forward and backward directions are opposite, so the front end surface abuts on the intermediate stopper 28, and the transfer deviation of the steel 13 between the stoppers 27, 28 is corrected.

Subsequently, the measuring cart 21 is moved to the band saw 15
With the mounting position O 'of the cutting blade 19 as the origin, it is moved from that position in the X direction by the dimension indicated on the second display unit 45, and then the intermediate stopper 28 is raised, and the steel material 13 is further moved by the roller conveyor 14. Loading table 11
Move to the side. During this time, the front end face (actually, the rear end face) of the steel material 13 is checked by the camera 23. When the front end face is found, the position of the front end face of the steel material 13 and the monitor are monitored in the same manner as in the case of the rear end face position of the steel material 13 described above. By making the base line 25 of the screen 24 coincide with the base line 25, the intermediate position of the steel material 13 is disposed immediately below the cutting blade 19.

Next, the steel 13 is clamped by the clamper of the band saw 15, and the steel 13 is clamped by the cutting blade 19.
At the middle position. Then, the cut small steel material 13 ′ is conveyed to the unloading table 12 side by the roller conveyor 14 after the clamped state is released by the clamper, and is taken out to the unloading table 11 by the transfer 18 </ b> B. Thereafter, by repeating the same operation, the steel material 13 on the carry-in side table 11 is sequentially cut into small steel materials 13 ′ by the band saw 15 on the way, and is conveyed onto the carry-out side table 12.

As described above, according to the present means, the length and the intermediate position of the steel material 13 are calculated based on the detection values of the encoder, and the intermediate position is cut by the band saw 15, so that the conventional means is used. There is no need for the operator to measure or mark the steel material 13 using a tape measure on the carry-in side table 11, so that a consistent steel material cutting operation from the length measurement to the cutting of the steel material 13 can be remotely controlled in the control room 17, and By this remote operation, dangerous human work on the carry-in side table 11 is eliminated, and work safety can be improved.

Although the embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and even if there are design changes and operation changes without departing from the gist of the present invention, the present invention is included in the present invention. It is. For example, in the embodiment, the steel object is exemplified as the object to be measured. However, the present invention is not limited to this. Further, in the embodiment, as a length measuring means of the measured object,
Although the encoder is shown, the length measuring means may have any structure without being limited thereto. Further, in the embodiment, the band saw is shown as the cutting device. However, the present invention is not limited to this, and any other cutting device may be used.
Furthermore, the length of the object to be measured does not need to be the moving distance of the length measuring cart from the origin position based on something other than the object to be measured as in the embodiment, for example, actually from one end of the object to be measured. The distance traveled by the length measuring cart to the other end can also be used.
Next, in the embodiment, the object to be measured is cut into two equal parts by the cutting device. However, the present invention is not limited to this, and may be cut into three or more parts. Further, in the embodiment, the length measurement position of the measured object is the end face of the measured object. However, the present invention is not limited to this, and may be an arbitrary position in the middle of the measured object. Further, in the embodiment, the objects to be measured are transported in a stacked state and cut together, but the invention is not limited thereto, and the objects to be measured can be transported one by one and cut.

[0022]

According to the length measuring / cutting method according to the first and second aspects and the steel length measuring / cutting equipment using the method, the object to be measured is measured based on the output value of the length measuring means.・
Since cutting is performed, there is no need for an operator to measure or mark steel using a tape measure on the carry-in side table as in conventional means, and therefore, consistent steel cutting from measuring to cutting of steel is not necessary. Work can be controlled remotely,
By this remote operation, dangerous human work on the carry-in side table is eliminated, and work safety can be improved. Also, the alignment between the rear end face position of the DUT and the baseline of the monitor screen is
Since the measurement is performed by eye measurement, even when measuring the length of a stacked object to be measured whose measurement positions are somewhat irregular, the measurement position can be arbitrarily corrected by the measurement person's judgment.
