Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a modular drive mechanism which allows the entire drive mechanism to be attached and detached with one touch.

[0002]

2. Description of the Related Art For example, in a feedback automatic control system, there are a drive device driven by a servo amplifier and an internal sensor for measuring a displacement amount of the drive device. In this case, as a conventional module type drive device in which the simultaneous use device is modularized, there is one in which the drive device and the internal sensor are incorporated, and for example, the servo amplifier is a separate body without being incorporated. In addition, the transmission form of the control signals of the drive device and the servo amplifier, the internal sensor and the servo amplifier, the internal sensor and the control panel is parallel transmission. Furthermore, the attachment / detachment of the above-mentioned modular drive device is performed separately for electrical attachment / detachment and mechanical attachment / detachment.

[0003]

However, the above-mentioned module type drive device is not a module structure as a whole but merely a module type drive device in which a drive device and an internal sensor are incorporated, and control signal transmission is parallel transmission. In addition, since electrical and mechanical attachment / detachment is performed, there are the following problems. That is, since the servo amplifier is not included in the drive device, it is necessary to replace it with a servo amplifier suitable for the drive device when attaching / detaching. For example, since the control signal transmission between the drive devices is parallel transmission, the number of signal lines to be connected when the drive device is attached / detached increases in proportion to the number of drive devices. When attaching and detaching the drive unit, a jig for electrical connection between the drive units and a jig for mechanical connection are required. In the case of a drive system, the number of signal lines and pin connection parts are determined by the position of the drive device, so the connection arrangement of the drive device is uniquely determined.
Moreover, it is not possible to share a drive device in one drive system with a drive device in another drive system.

In view of the above problems, the present invention has an object to provide a drive mechanism in which the entire drive mechanism is modularized.

[0005]

SUMMARY OF THE INVENTION The present invention for achieving the above object includes a servo amplifier for driving a drive device based on a control signal, and an internal sensor for detecting a control signal necessary for controlling the drive device. It is characterized by modularizing a control signal transmitting / receiving unit for transmitting / receiving control signals and a one-touch detachable mechanical / electrical type connector as an input / output terminal.

[0006]

[Function] The control signals of the modular drive mechanism can be transmitted / received serially, and the drive mechanism can be attached / detached only by the electromechanical integrated connector, and the drive mechanism can be arranged arbitrarily in the drive system. Can be shared.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A module type drive mechanism according to an embodiment of the present invention will be described with reference to FIG. In FIG. 1, there is an electromechanical-integrated connector 1 as an input / output detachable terminal of a modular drive mechanism which is wholly modularized. A power line 2 and a signal line 3 are connected to the connector 1. A power line relay contact 23, which is a switch, is interposed in the power line 2 to turn it on and off. Power line 2
Is connected to the DC / DC converter 4 and constitutes a power supply circuit.

A control signal receiving interface 5 and a control signal transmitting interface 13 are connected to the signal line 3. Among these, the control signal receiving interface 5 is connected to the D / O converter 7 or the D / A converter 10 via the control signal receiving bus 6, and the D / O converter 7 drives the power line relay coil 8 and the drive. The brake 9 of the device 12 is connected. Further, the D / O converter 7 and the D / A converter 10 are connected to the driving device 12 via the servo amplifier 11.

On the other hand, as the internal sensor, the current detector 1
9, a speed detector 20 and a position detector 21 are provided, and the respective detectors are connected to the current detector signal converter 15, the speed detector signal converter 16 and the position detector signal converter 17 to send control signals. It is connected to the control signal transmitting interface 13 via the trust bus 14. Further, the abnormality detector 22, which is an internal sensor, also includes the D / I converter 18 and the bus 14.
It is connected to the control signal transmitting interface 13 via.

The attachment / detachment between the module-type drive mechanisms can be done by one-touch by the electromechanical integrated connector 1.
By connecting the mechanical-electrical integrated connector 1, the power line 2 and the signal line 3 are electrically connected. The control command from the control panel is received by the control signal receiving interface 5 through the signal line 3. The interface 5 recognizes the address in the control command and determines whether or not the destination of the command value is itself. If this command value is for itself, this command value is sent to D / V via the control signal receiving bus 6.
It is transmitted to the O converter 7 and the D / A converter 10. The D / O converter 7 follows the control command and supplies the power line relay coil 8
And activate the brake 9. When the power line relay coil 8 is activated, the power line relay 23 is activated and power is supplied to the module drive mechanism of the next stage. Also, D /
The A converter 10 outputs an operation command to the servo amplifier 11 according to the received control command value.

The control signal transmission interface 13 is a current detector 1 which is an internal sensor of the module type drive mechanism.
9. Speed detector 20, position detector 21, abnormality detector 22
Each detection signal from the current detector is converted into a current detector signal converter 15, a speed detector signal converter 16, and a position detector signal converter 17.
The parallel signal obtained via the D / I converter 18 is converted into a serial signal, and the serial transmission data of this detection signal is superposed with its own address and placed on the signal line 3.

[0012]

As described above, according to the present invention, since the servo amplifier is included in the drive mechanism, there is no need to replace the servo amplifier, and the module is modularized as a whole. It fits inside and can be connected with the mechanical-electrical integrated connector without distinction between electrical connection and mechanical connection as in the past, and since the control signal transmission between module type drive devices is serial transmission, when attaching and detaching the drive mechanism The number of signal lines to be connected to and the pin assignment are the same regardless of the position of the main drive mechanism in the drive system, the attachment / detachment of the drive mechanism and the arrangement of the drive mechanism in the drive system can be arbitrarily set, and further,
Due to address management in the drive system of the module type drive mechanism and connection by the electromechanical integrated connector of the drive mechanism comrades, as long as the addresses of the module comrades do not overlap
It can be shared as a drive mechanism for other drive systems.
