At the same time as the position detector (3) turns on and detects this, the pulse integration circuit (5) starts integrating, and the measured object (4) moves in the longitudinal direction of the object (4), that is, in the direction of the arrow fAl. A pulse signal proportional to the amount of movement to be carried is output from the pulse generator (2) and counted by the pulse integration circuit (5). Then, when the rear end of the object to be measured (4) passes through a predetermined position, the position detector (3) operates OF'F', and the pulse integration circuit (
Although the counting operation in step 5) stops, the pulse amount corresponding to the length from the tip to the rear end of the object to be measured (4) has been integrated in the pulse integration circuit (5) by the above-mentioned operation. This total pulse amount is calculated by the length calculation circuit (6)
1, the length of the object to be measured (4) converted into a practical unit of length is output as a length output (force).

示すような状態で被計測体(4)の信号が記憶される。Since the length measuring device of the present invention is configured as described above, when a large number of objects to be measured (4) made of long materials are transported by one transport device (1) such as a roller table, From the point at which the leading edge of the object to be measured (4) passes the position detectors (3), the one-dimensional scanning camera (11) scans in the line width direction for detection. A converter (12
)I is thus quantized and stored in the storage circuit (14) by the transfer circuit (13).If the resolution in the line width direction of this -dimensional scanning camera (11) is N bits, then In FIG. M2, the signal of the object to be measured (4) is stored in the state shown in the "first line".

Cなされており、その結果を第3図に示している。By repeating the above-mentioned operation, for example, M times, the image of the end of the object to be measured (4) is created every fixed length in the traveling direction as described above.
M lines are detected, and the memory circuit 14) is detected.
The signal of the image of the object to be measured (4) of “line x N bits” is the second signal.
It is stored as shown in the figure. This figure 2 shows the object to be measured in the memory circuit (14) in a state where the above-mentioned M line is read in the tip of the object to be measured (4) at regular intervals with a one-dimensional scanning camera (11). This shows the storage state of the image signal of the image signal of the light source (
The signal is low at locations where the object to be measured (4) blocks the light from the light source (24), and the signal is high at locations where the light from the light source (24) is not blocked. It goes without saying that the quantization level of the width converter (12) 1 can be arbitrarily set depending on the application. I want to binarize the “Mth line” signal string in (14) using an appropriate “threshold value”.
The results are shown in Figure 3.

Find J. This will cause the address rMaJ Kara I”
The number of data up to Ml corresponds to the end portion of the object to be measured (4). In addition, above [point b J, f''cJ
It goes without saying that similar processing is performed for J as well. Now, if we assume that the result of reading the image of the object to be measured (4) every 10IIIK in the running direction is the state of the memory circuit (14w) shown in FIG. 2, then the tip of the object to be measured (4) The length can be determined as [c M-Ma )Xl 01jJ. It is no secret that the same is true for "point b" and "point 0." The length of the tip of the object to be measured (4) obtained in this way rtLl, r4J

This will be remembered. Also, the length I of the rear end of the object to be measured (4)
If you get stuck, it will be handled in the same way.

This allows the individual lengths of each object to be measured (4) to be measured simultaneously.

First, the image of the object to be measured (4) is changed from the ``2nd line'' to the ``M line'' from the time determined by the leading edge position detector (3J, <3) of the object to be measured (4) which is the most preceding. Read up to "eyes". When this reading is completed, the above-mentioned length calculation process for the leading and trailing ends begins. Simultaneously and in parallel, the pulse integration circuit (18) starts integrating the pulses from the pulse oscillator (2) from the time the reading is completed.

先端部長さ演算回路(15)によって行なわれ。Next, when the final end of the plurality of objects to be measured (4) being transported is detected by the position detectors (21) and (21), the integration of the pulse integration circuit (18) is stopped. At the same time, the object to be measured (4) is scanned by a -dimensional scanning camera (11).
), and reads for 1'-M lines. At this point, the length of the tip is already 11.1! ,...Since the stone has been calculated and stored in the register for the tip (16), reading the image of the rear end and calculating the length of the rear end are performed in the same way as for the tip. This is performed by the length calculation circuit (15).
その結果、後端部の長さA1’ 、 1.2 、13′

The total length of the object to be measured (4) is calculated individually using It goes without saying that similar effects can be obtained by detecting the lengths of the leading and trailing ends of the object to be measured (4) using a two-dimensional scanning camera. Furthermore, if the object to be measured (4) is a high-temperature material, the light source (24) may be omitted and the radiant heat of the object to be measured itself may be directly detected by a camera for dimensional scanning or the like.

By two-dimensionally capturing the amount of unevenness in the transport direction of each object to be measured with respect to its leading and trailing ends, it is possible to simultaneously measure the individual lengths of each object to be measured. It is effective.
