一般である。2. Description of the Related Art An extrusion molding line is a rubber or plastic material extruded by a screw extruder into a long material having a required cross section, which is vulcanized, crosslinked, cooled, and wound or cut into a required size. Refers to the entire equipment or the first half of the equipment. For the speed setting of the extrusion molding line, the speed of each device constituting the line is set individually so as to be harmonized as a whole. In order to set a line speed suitable for producing a certain product, which device is set at what speed is generally obtained from a empirically obtained list or the like.

ゆかない。Therefore, the field engineer selects a set speed suitable for the product for which the production command has been received, sets it in the drive unit control device of each device of the line, and carries out a trial operation. As a result, when it is confirmed that the required product can be obtained, full-scale production is started. The speed setting of the tasshi extrusion molding line is
In addition to the hassle of setting each device individually, picking one extruder is not as easy as setting the speed of the motor.

The extruder is trial-operated by the obtained command voltage and the screw rotation speed is measured and compared with the required rotation speed. Then, the command voltage is adjusted so that the measured value and the required value are closer to each other, and the trial operation is repeated many times. Since it takes time from the start of the extruder by the command voltage until it reaches a stable speed, the above speed setting work was an unexpectedly time and nerve consuming work.

Not a little affected. Therefore, the present inventor does not set the speed of the line by trial and error as in the past, and does not set each device individually but collectively,
I thought about developing a device that can set the speed once.

る。A speed setting device for an extrusion molding line according to the present invention outputs a speed command voltage to each device of the extrusion molding line and inputs a speed measurement value from each device. Each device receives the speed command voltage, adjusts the drive speed of the device to the command voltage, waits for a stabilization time, and sends the measured value of the attached speed measurement unit to the control computer unit. Consisting of a control device of the device, the control computer unit, the command voltage for commanding the practical maximum speed of each device the maximum value, the command voltage test output stepwise from the maximum value to zero,
It is characterized in that a command voltage-stable speed characteristic curve drawn on a voltage-speed coordinate axis on a computer is recorded from a stable speed measurement value of the device corresponding to each voltage value.

The control computer unit is connected to the drive unit and speed measurement unit of each device that configures the line. When a speed command signal (voltage) is output to each drive unit, each speed is waited for a certain stabilization time, The measurement value of the measurement unit is returned. Therefore, if the command voltage is changed and output, the speed measurement values are input one after another.

By inputting the value, the control computer unit stores the command voltage-stable speed characteristic curve of each device.

After receiving the command voltage, each device is driven at the required set speed after the stabilization waiting time, and all the lines are collectively set once to obtain the required line speed.

略す。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram showing the outline of the constitution of the present invention, and although the extrusion molding line is represented by drawing only one unit of each device, of course, all the devices for speed setting are as shown in the figure. Are connected to the same control computer unit. The control computer section sends a speed command voltage from the analog output section (D / A) to the control device of each device in the line.
The control device of each device adjusts the device drive speed according to the command voltage. As a result, after a stabilization wait time until the speed of the device changes and stabilizes, the speed measurement unit attached to the device digitally inputs the measured value (revolutions / minute or m / minute) via the data converter. From the department to the control computer department. Since the details of this portion belong to the well-known technology, the description thereof is omitted.

として選んだ押出機スクリューの回転数／分である。As described above, when the control computer section sends the speed command voltage to each device in the line, the stable speed measurement value of each device based on the command voltage is automatically returned. Therefore, the characteristic curve of the speed command voltage and the speed of each device resulting therefrom can be easily recorded in the computer. FIG. 2 is a characteristic curve 3 of command voltage-rotation speed drawn on a voltage-speed (rotation speed) coordinate axis on a computer.
And the procedure for creating it. The "output voltage" on the horizontal axis of the figure is the speed command voltage, and the "rotation speed" on the vertical axis is the rotation speed / minute of the extruder screw selected as an example of each line device.

Point d is the origin of zero voltage and speed, and point a is the point of the voltage and speed a of the characteristic curve. Therefore, in order to derive the diagonal line 1 connecting the points a and d, the setting screen of Table 1 is prepared, the output voltage at the practical maximum rotation speed is given as a numerical value, and the point d is connected to the origin.

The points c and c are obtained to obtain a rough characteristic curve 3.

It goes without saying that the more the number of divisions is increased, the closer to the true characteristic curve is obtained.

行い得るのである。Although the method of recording the characteristic curve of the extruder has been described on behalf of each apparatus of the extrusion molding line, the characteristic curve of each apparatus of the line is similarly recorded.
This seems to be troublesome, but by doing so, it is possible to collectively set the speed of each device when changing products without trial and error.

In this case, the control computer section changes the output voltage V 1 to V 9 for commanding the speed to the extruder control device 9 times to perform a trial operation, and obtains the stable speeds R 1 to R 9 measured after the speed stabilization waiting time 9 Since this is a repetitive work, the number of times counter n is set to 1 after "start". When n = 1, the voltage V 1 is output to the analog output section (D / A) of the control computer section. After that, as shown in FIG. 4, after a stabilization waiting time (for example, 4 seconds), the measurement rotation speed / minute R 1 sent is read.

ることは言うまでもない。When the extruder recording the characteristic curve 3 of FIG. 3 is set to a new line speed of revolutions / minute, if the revolution is intermediate between R 5 and R 6 of FIG. 3 (R 5 + dR). From the point X of the characteristic curve 3, the output voltage becomes (V 5 + dV).
Only dV is an unknown number, and the formula for calculating this is as follows. dV / dR = (V 6 −V 5 ) / (R 6 −R 5 ) ∴dV = dR · (V 6 −V 5 ) / (R 6 −R 5 ) Due to the above, the required output voltage is V 5 + dV = V 5 + dR · (V 6 -V 5) / (R 6 -R 5) to be calculated. Although one embodiment has been described above, it is needless to say that the present invention can be variously changed and applied according to a known technique of a control engineer according to an implementation condition without changing the gist thereof.

効果は極めて大きい。According to the present invention, in an extrusion molding line, which is a typical multi-product small-scale mass production facility, each line device is set to a speed necessary for experience in order to change the line speed each time the product type changes. The troublesome work of fixing has been dramatically simplified. It introduced a small computer that controls the entire line, and not only did it output the speed command voltage to each device in the line, but also memorized the command voltage-stable speed characteristic curve of each device. Eliminating the error-setting speed setting work, the speed of each device can be set accurately at once. The effect of improving productivity is extremely large.
