The driver 10 and the power source 5 are connected by the power wiring 12b. The electric power output from the power source 5 is supplied to the driver 10 through the power wiring 12b.

The controller 9 and the power source 5 are connected by the power wiring 12f. The power output from the power source 5 is supplied to the controller 9 through the power wiring 12f.

The controller 9 and the driver 10 are connected by a signal wiring 13b. A power supply command and a motor control signal are generated at the controller 9. The power supply command is transmitted to the driver 10 through the signal wiring 13b.

The driver 10 operates in accordance with a power supply command and outputs electric power required to drive the motor 3.

The relay circuit unit 14 of the first embodiment is configured to be connectable to at least a distance sensor 4a and a temperature sensor 4b belonging to a sensor for controlling the operation of the motor 3. The relay circuit unit 14 receives the detection signal output from at least one of the distance sensor 4a and the temperature sensor 4b, and relays it to the control unit 30. That is, the relay circuit unit 14 relays signals transmitted between at least the control unit 30 and the motor 3.

Further, the relay circuit unit 14 of the first embodiment receives the motor control signal transmitted from the control unit 30 and relays it to the motor 3.

The rechargeable battery 15 and the temperature sensor 4b are connected by the power wiring 12d. The electric power output from the rechargeable battery 15 is supplied to the temperature sensor 4b through the power wiring 12d.

The relay circuit unit 14 and the motor 3 are connected by the power wiring 12g and the signal wiring 13g.

The relay circuit unit 14 and the driver 10 are connected by the power wiring 12a and the signal wiring 13a. At least one of the power wiring 12a and the signal wiring 13a is provided between the control unit 30 and the relay circuit unit 14, and only wiring for controlling the number of motors 3 is provided.

The motor control signal generated by the controller 9 is transmitted to the relay circuit unit 14 through the signal wiring 13a. The motor control signal transmitted to the relay circuit unit 14 is transmitted to the motor 3 through the signal wiring 13g.

The relay circuit unit 14 has an input unit 33, and the input unit The 33 inputs the detection signals output from the distance sensor 4a and the temperature sensor 4b to the relay circuit unit 14.

Further, the relay circuit unit 14 includes a communication unit 31 as an interface for connecting the signal wiring 13a to the relay circuit unit 14.

The processing unit 32 transmits the detection signal input to the input unit 33 to the control unit 30 using the idle time other than the time required for the control of the motor 3 . For example, in order to control the motor 3 while maintaining a fixed precision, it is necessary to apply a plurality of digital signals to the motor 3 at regular intervals. The above idle time is equivalent to the time between digital signals transmitted at regular intervals.

Further, the processing unit 32 transmits the motor control signal transmitted from the control unit 30 to the motor 3 via the signal wiring 13g.

The operation of the manufacturing system 100 will be described.

When the workpiece 7 is conveyed by the belt conveyor 6, and the workpiece 7 is detected by the distance sensor 4a, the detection signal detected by the distance sensor 4a is transmitted through the relay circuit unit 14 and The signal wiring 13a is transmitted to the control unit 30.

In the motor 3, the timing of the machining device 8 is determined based on the motor driving power and the motor control signal, and the workpiece 7 is processed by the processing device 8.

The processing unit 32 of the relay circuit unit 14 receives a feedback signal output from the motor 3. The feedback signal is transmitted to the control unit 30 through the communication unit 31 and the signal wiring 13a.

In the control device 101, the signal wiring for control in the motor 3 is shared for the transmission of the detection signal. Further, the number of signal wires 13a and the number of signal wires 13g are the same.

On the other hand, in order to prevent the rotation precision of the motor 3 from decreasing, it is necessary to transmit the feedback signal of the motor 3 to the signal wiring 13a at a fixed transmission speed.

Therefore, the processing unit 32 of the relay circuit unit 14 performs signal processing so as to control the motor 3 to transmit a detection signal during an idle time other than the time required for control.

The controller 9 determines whether the received signal belongs to a signal output only from the motor 3 or a signal output from each of the motor 3, the distance sensor 4a, and the temperature sensor 4b, and controls the motor. 3. Processing is performed in the manner of the distance sensor 4a and the temperature sensor 4b.

In the control device 101 of the first embodiment, even if a new sensor is added, it is only necessary to add a signal wiring for connecting the new sensor to the relay circuit unit 14.

Thereby, the sensor can be added without providing a new wiring between the control panel 2 and the manufacturing apparatus 1.

Therefore, a new sensor can be added while suppressing the man-hours for providing wiring, and the controllability of the control device 101 and the motor 3 can be improved.

Further, in the case of comparing the conventional control device and the control device 101 of the first embodiment, the control device 101 can shorten the signal wirings 13c and 13d connected to the distance sensor 4a and the temperature sensor 4b.

In particular, as shown in Fig. 1, the manufacturing system 100 provided separately between the control panel 2 and the manufacturing apparatus 1 is required to be large as compared with the case where the control panel 2 and the manufacturing apparatus 1 are integrally provided. Therefore, the distance between the manufacturing apparatus 1 of the manufacturing system 100 and the control panel 2 becomes longer as compared with the case where the control panel 2 is integrally formed with the manufacturing apparatus 1.

On the other hand, the sensor 4 must be placed at a place where the state of the motor 3 can be monitored. In particular, since the distance sensor 4a is used to determine the timing at which the processing device 8 is driven by the motor 3, it is necessary to detect that the workpiece 7 is transported to the vicinity of the processing device 8 by the belt conveyor 6. Therefore, there is a high possibility that the distance sensor 4a is disposed in the vicinity of the motor 3.

For example, the case of the manufacturing apparatus 1 having a width of 20 cm of the belt conveyor 6 will be described as an example, wherein the belt conveyor 6 is handled. The processed product 7 having an outer diameter of 10 cm. In this case, it is assumed that the motor 3 and the distance sensor 4a need to have a distance of 50 cm, a distance of 20 cm between the distance sensor 4a and the rechargeable battery 15 is required, and a distance of 3 m between the motor 3 and the driver 10 is required.

At this time, the total length of the wiring lengths of the signal wirings 13c, 13d, and 13g and the wiring length of the signal wiring 13a is 9 m in the case of a manufacturing system using a conventional control device.

On the other hand, in the manufacturing system 100 using the control device 101 of the first embodiment, the total length of the wiring length is 4 m. As described above, according to the control device 101 of the first embodiment, there is a possibility that the wiring is completed by less than half of the conventionally known wiring.

Further, according to the first embodiment, since the signal wires 13c and 13d are shortened as compared with the conventional one, the electromagnetic noise caused by the detection signals transmitted to the signal wires 13c and 13d is lowered.

Therefore, even if the control sensor (not shown) is incorporated in the motor 3, the influence of electromagnetic noise on the sensor for control is reduced. This control sensor is a precision product provided for controlling the motor 3 with high precision.

Further, even in the sensor provided outside the motor 3 as in the distance sensor 4a, the signal wirings 13c and 13d are shortened as compared with the conventional one, and the noise resistance is improved.

Further, as an example of the prior art, there is a product in which the motor and the driver are integrally provided, and the driver has an input function of an external sensor. However, since both the motor and the driver belong to the hair Since heat and electromagnetic waves generate equipment, if they exist in the vicinity, countermeasures against heat and electromagnetic waves of each other are required.

According to the manufacturing system of the first embodiment, since the relay circuit unit 14 and the driver 10 are separated, it is not necessary to take countermeasures as described above, and the cost associated with the countermeasure can be suppressed.

Further, although the control panel 2 of the first embodiment is provided with the driver 10, the configuration of the control panel 2 is not limited thereto. The driver 10 is not required according to the type of the motor 3, in which case the signals output from the motor 3, the distance sensor 4a, and the temperature sensor 4b are input to the controller 9, and the motor is driven by the controller 9. 3.

Further, although the relay circuit unit 14 of the first embodiment has the input unit 33, it may have an output unit other than the input unit 33, and the output unit has a signal output function. A sensor having a monitoring function such as a display is connected to the output unit, and the sensor operates by receiving a signal from the output unit.

Thereby, it is possible to suppress the wiring cost without resetting the wiring for the sensor between the control panel 2 and the manufacturing apparatus 1.

Further, the distance sensor 4a and the temperature sensor 4b of the first embodiment may be those that output a detection signal by a digital signal, or may output a detection signal by an analog signal. When the distance sensor 4a and the temperature sensor 4b output a detection signal with an analog signal, the relay circuit unit 14 receives the analog signal, and the processing unit 32 of the relay circuit unit 14 converts the analog signal into The digital signal is transmitted to the control unit 30. With this configuration, even an analog analog signal is output as a torque sensor The sensor can also be connected to the manufacturing apparatus 1 and improve the controllability of the motor 3.

In addition, the function of the controller 9 of the implementation mode 1 can be implemented by using hardware configured inside the control panel 2, or by executing a server connected to the network. A program that implements the functions of the controller 9 is implemented. The network can also be an intranet, an internet, or a cloud network.

Further, the relay circuit unit 14 of the first embodiment may be provided inside the motor 3. However, when the function of the relay circuit unit 14 is realized by the circuit on the circuit board of the motor 3, the noise resistance is lowered. Therefore, in the case where the relay circuit unit 14 is provided inside the motor 3, it is preferable that the relay circuit unit 14 is realized by a component disposed on a portion other than the circuit board of the motor 3.

Further, the sensor connected to the relay circuit unit 14 of the implementation type 1 is not limited to the distance sensor 4a and the temperature sensor 4b, and may be a monitor device such as a display or an actuator. (actuator).

Further, according to the first embodiment, since the wiring for transmitting the detection signal can be shortened, the noise resistance is improved. Further, in the case where the motor 3 is a servo motor, the angle detector for detecting the rotation angle of the servo motor is connected to the relay circuit unit 14, whereby the exchange and repair of the angle sensor are facilitated.

Further, in the conventional control device, there is a product in which the motor 3 and the driver 10 are integrally formed, and the driver 10 has The function that inputs the signal from the external sensor. However, since both the motor 3 and the driver 10 are heat generating devices, and electromagnetic waves are generated, if they are placed in the vicinity, they are affected by heat and electromagnetic waves, and it is necessary to alleviate such influences.

According to the first embodiment, since the motor 3 is connected to the driver 10 through the relay circuit unit 14, the distance between the motor 3 and the driver 10 is relatively increased. Therefore, the countermeasures such as mitigating the influence of heat and electromagnetic waves between the motor 3 and the driver 10 are not performed, and the motor 3 can be controlled with excellent precision.

Further, the control unit 30 of the first embodiment may have the controller 9 provided with the function of the driver 10, and for example, the controller 9 may be provided with a power amplification function. Further, the driver 10 can also be provided with the function of the controller 9. Further, the control unit 30 may be configured as an amplifier that combines the functions of the controller 9 and the driver 10.

Further, the motor 3 of the first embodiment is not limited to a servo motor, and may be various motors other than the servo motor.

Further, in the first embodiment, the signal wiring 13a between the motor 3 and the relay circuit unit 14 can be used for the signal wiring for control in the conventional motor. Further, the signal wiring 13a may be shared as a wiring for signal transmission for the sensor. Thereby, the device can be constructed with a minimum number of pieces. However, depending on the configuration of the device, a signal line of the motor 3, a signal line of a sensor (not shown) other than the sensor 4, and a signal line of the actuator may be connected in parallel to the relay circuit unit 14. possibility. At this time, the wiring between the motor 3 and the relay circuit portion 14 is formed to be controlled. The number of strips required to make the motor 3 is still large.

In the fourth drawing, a part of the power wiring constituting the control device 101-2 of the second embodiment is shown, but the signal wiring is omitted.

The difference from the embodiment 1 is as follows.

(6) The distance sensor 4a is connected to the constant voltage output unit 39 via the power wiring 12c.

(7) The temperature sensor 4b is connected to the constant voltage output unit 39 via the power wiring 12d.

The distance detector 4a and the temperature sensor 4b wirelessly output detection signals, and the detection signals are received by the controller 9.

In the control device 101-2, the power supply wiring for the drive 3 is used for the power supply of the sensor. Further, the number of power wirings 12a and the number of power wirings 12g are the same.

On the other hand, in order to prevent a decrease in the rotational precision of the motor 3, it is necessary to stably supply power to the drive motor 3 in the power wiring 12g.

Therefore, the processing unit 37 of the relay circuit unit 14-2 is configured to appropriately supply power to the motor 3, the distance sensor 4a, and the temperature sensor 4b.

When the power supplied from the control unit 30 is sent to the motor 3, the relay circuit unit 14-2 distributes a part of the power supplied from the control unit 30 to the distance sensor 4a and the temperature sensor 4b.

In addition, as long as the specifications of the power conversion unit 38 and the constant voltage output unit 39 are within the range of the specifications of the power conversion unit 38 and the constant voltage output unit 39, sensors other than the distance sensor 4a and the temperature sensor 4b can be added to the constant voltage output unit 39.

According to the control device 101-2 of the second embodiment, even if a new sensor is added, it is only necessary to add a power wiring for connecting the new sensor to the relay circuit unit 14-2.

Thereby, the sensor can be added between the control panel 2 and the manufacturing apparatus 1-2 without providing a new wiring. Therefore, a new sensor can be added while suppressing the man-hours for setting the wiring, and the controllability of the control device 101-2 and the motor 3 can be improved.

In addition, in the case of comparing the conventional control device with the control device 101-2 of the embodiment 2, the control device 101-2 can shorten the power connected to the distance sensor 4a and the temperature sensor 4b by a conventional control device. Wirings 12c and 12d are used.

Further, according to the control device 101-2 of the second embodiment, the existing power supply 12a for driving in the motor 3 can be utilized. Therefore, in the case where the distance sensor 4a and the temperature sensor 4b are not required, the relay circuit unit 14-2 is omitted, and the power wiring 12a is connected to the motor 3, whereby the motor can be driven. Motor 3.

Further, according to the control device 101-2 of the second embodiment, by adding the relay circuit unit 14-2, electric power can be supplied to the distance sensor 4a and the temperature sensor 4b. Therefore, it is not necessary to wire the distance sensor 4a and the new wiring for the temperature sensor 4b between the respective sensors and the control panel 2. Therefore, the cost associated with wiring can be suppressed.

Further, the relay circuit unit 14-2 of the second embodiment may be provided inside the motor 3. However, when the function of the relay circuit unit 14-2 is realized by the circuit on the circuit board of the motor 3, the noise resistance is lowered. Therefore, in the case where the relay circuit unit 14-2 is provided inside the motor 3, it is preferable that the relay circuit unit 14-2 is realized by a component disposed on a portion other than the circuit board of the motor 3.

In addition, the sensor connected to the relay circuit unit 14-2 of the implementation type 2 is not limited to the distance sensor 4a and the temperature sensor 4b, and may be a monitoring device such as a display. Actuator.

The power required by the vibration sensor 4f and the thermal sensor 4g is supplied through the relay circuit unit 14.

The control device 101-12 uses the signal wiring for control in the motor 3-12 for the transmission of the detection signal.

The relay circuit unit 14 not only processes the detection signal but also monitors whether or not the motor 3-12 is abnormal. When the vibration or the heat exceeds the set abnormal value, the processing unit 32 of the relay circuit unit 14 stops the power supply for the motor 3-12.

According to the embodiment 12, the same effects as in the first embodiment can be obtained. Furthermore, when an abnormality occurs in any of the motor 3-12 and the control device 101-12, the relay circuit portion 14 is interrupted for the controller 9 for power The power supply of the motives 3-12 can stop the abnormal state as soon as possible. Therefore, it is possible to detect the abnormality and safely use the motor 3-12 and the control device 101-12.

In addition, when the sensor is faulty, if the sensor is connected to a circuit board (not shown) in the motor 3-12, when the sensor is replaced, it takes time to change the wiring between the sensor and the substrate. operation. According to the embodiment 12, since the sensor is connected only to the signal wirings 13m and 13n extending from the relay circuit unit 14, the operation time at the time of wiring change can be shortened.

The configuration shown in the above embodiments shows an example of the present invention, and can be combined with other conventional techniques, and a part of the configuration can be omitted or changed without departing from the gist of the present invention.
