DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention apparatus will be described below with reference to the drawings when applied to a rolling control system. FIG. 1 is a diagram showing a schematic configuration of the apparatus, in which A shows a winding line system and B shows a rewinding line system.

Further, the winding line system A and the unwinding line system B are provided with the following functions. That is, a pulse generator 21 that generates a pulse proportional to the number of rotations of the roll is attached to a predetermined rolling roll 11 constituting a part of the winding line system A, and this pulse is used as a speed converter to detect the rate of change in line speed. The reference processing period signal output section 23 outputs a processing period signal corresponding to the number of revolutions of the section 22 and the take-up roll 13. Further, an A/D converter 24 is connected to the output side of the specific data detecting means 14, and outputs specific data that has been converted into a binary value depending on, for example, whether there is a flaw or whether a predetermined length has been reached. It has the function of Further, a pulse generator 25 that generates a pulse every 1/10 of the roll rotation speed, for example, is directly connected to the take-up roll 13, and the pulses generated by this generator 25 are counted by a counter 26. There is. Reference numeral 27 denotes an arithmetic processing control means, which is composed of, for example, a microcomputer, and is configured to process specific data outputted from the A/D converter 24 every second and the counter 26.
The rotational speed data of the winding roll 13 counted in is read and sequentially stored in the storage unit 28 which is constituted by a ring counter etc., and based on the processing cycle signal output from the reference processing cycle output unit 23. 1 of winding roll 13
For each rotation, specific data is sequentially rearranged to determine whether specific data is present or not. 29 is a distance correction means, which performs calculations when the speed changes in the speed converter 22 to correct the number of windings of the take-up roll 13;
It has a function of reflecting this in the rotation speed data in the storage section 28. Specifically, the correction signal N is obtained by calculating L/X=T/P. However, L is the specific data detection means 14
distance from to the center of the take-up roll 13, × is the line speed,
P indicates the pulse increase/decrease of the counter 26.

On the other hand, in the unwinding line system B, the winding roll 13'
A pulse generator 31 is connected to the rotating shaft of the motor, and output pulses from the pulse generator 31 are supplied to a counter 32 and, if necessary, a speed converter 33.

This counter 32 is used to count the number of unwinding rotations when unwinding the strip 12 from the take-up roll 13' and supply it to the arithmetic processing control means 27, and to read out the data stored in the storage section 28 in reverse. It is.

Reference numeral 34 denotes a cutter drive section, which operates with a control signal output from the arithmetic processing control means 27 based on the read data, and drives the cutter rock structure 16. 35

It has a function of correcting the distance, that is, correcting the rotational speed data in accordance with the speed change, and storing the reversely read specific data in the storage section 28 again.

Next, the operation of the apparatus configured as above will be explained.

(1) When cutting the strip 12 into sections or a predetermined length.

In the rolling control system, the slab 10 is connected to the rolling roll 11
... is rolled into a strip 12 of a predetermined thickness and wound onto a take-up roll 13. At this time, the specific data detection means 14 detects specific data on the presence or absence of flaws or a predetermined length, Also, the rotation speed of the take-up roll 13 is 1/10
Each rotation, the pulse generator 25 generates a pulse and outputs it, and the counter 26 integrates the pulse. Then, these specific data and rotation speed data are read every second, for example, by a clock from a clock generation source built in the arithmetic processing control means 27, and are sequentially stored in a ring counter or the like of the storage section 28. Figure 2 a, b). At this time, since the specific data detection point and the position of the winding roll 13 are different, the corresponding relationship is determined and stored in advance in the memory of the storage unit 28, for example. Note that FIG. 2a shows rotation speed data, and FIG. 2a shows specific data such as the presence or absence of a flaw or the presence or absence of a predetermined length.

The data is sequentially stored in the storage unit 28 as described above, but each time the strip 12 reaches a predetermined length, a processing cycle signal is generated from the reference processing cycle output unit 23, and based on this, the processing cycle signal shown in FIG. Data a and b are classified into presence or absence of specific data for each take-up roll rotation speed. In other words, the rotation speed data per second is shown from the right side of Figure 2a.
, 1~1, O), no specific data, 2nd rotation (1, 1~
2.0), there is no specific data, and the third and fourth rotations are similarly classified as having specific data, and the storage order is rearranged as shown in FIG.

Although the above storage order is an example of a constant speed, for example, if there is a speed change in the winding line system A, the speed converter 22 detects it, and the distance corrector 29 adjusts the specific data detection point to the above-mentioned specific data detection point. Using the distance to the central axis of the take-up roll, the baros increase/decrease P of the counter 26 representing the traveling distance per second corresponding to the winding diameter of the take-up roll 13 at that time, and the speed X at that time, T= (L/x)・P to obtain a correction signal T, correct the rotation speed data shown in FIG. Categorize and memorize.

Thereafter, after moving the winding roll 13 to a predetermined location, when the winding roll 13' is rewound, the arithmetic processing opening means 27 calculates the data shown in FIG. 3 based on the rotational speed data of the counter 32. Reading is performed in the direction of the arrow in FIG. It's something to cut.

(2) A case where the strip is simply wound up with the rewinding roll 15 without cutting it.

In this case, the order of storing and reading data in the steps shown in FIGS. 2 to 4 is the same as in item (1) above. What is particularly different is that the rotation speed data of the rewinding roll 15 is taken out using a pulse generator 35 and a counter 36;
This allows the data that has been read through to be rearranged. At this time, if there is a speed change in the rewinding line system B, the speed converter 33 and the distance correcting means 37 correct the distance, and then check the presence or absence of specific data every time the rewinding roll 13 rotates, as in FIG. It is something to remember.

Therefore, according to the configuration of the embodiment as described above, the specific data is stored in the order of the number of windings of the winding roll 13, and the specific data is read out in the reverse order when the strip 12 is unwound by the winding roll. Cutting is done according to flaws or a predetermined length, or rearranged according to the number of turns of the re-wound roll, eliminating the hassle of marking and visually observing it, and also automating the cutting work. and greatly contributes to efficiency. In addition, it is possible to solve the problem of stains remaining on the product because no markings are attached.

In the above embodiment, the processing cycle signal is obtained from the reference processing cycle output section 23 from the rolling roll 11 via the pulse generator 21, but the processing cycle signal is obtained by counting the pulses output from the pulse generator 25. A signal may also be obtained. In addition, the present invention can be implemented with various modifications without departing from the gist thereof.

〔Effect of the invention〕

As described in detail above, according to the present invention, a section or a predetermined length of specific data is captured and stored from a strip without marking, and when the tape is rewound, the stored data is read out in reverse to save a predetermined portion of the strip. Since the signal for cutting, etc. is extracted, it is possible to provide a winding/rewinding device that can improve the efficiency of cutting work and ship products without stains.
