Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for controlling various devices such as a positioning device.

[0002]

2. Description of the Related Art In recent years, a positioning device has been often used which positions a load in a linear direction by converting a rotational motion of an electric motor into a linear motion by a ball screw or the like and controlling the electric motor.

In order to control such a positioning device, a control device for controlling the rotation speed or rotation speed of the electric motor is used. The conventional control device has a rectangular parallelepiped case, and has a structure in which electric circuit components for control are housed in the case. An operation panel surface for operating the control device is provided on the front surface of the case. And a wiring connection surface for connecting wiring to the control device is formed on the back surface of the case.

[0004]

Therefore, in using the conventional control device, the operation panel surface of the control device is located on the front side of the control panel in the control panel for totally controlling the mechanical system including the positioning device. By installing the control device so that it is on the door side and connecting the wiring to the wiring connection surface using the duct etc. provided in the control panel, and operating the operation panel surface from the front side of the control panel. The positioning device is controlled.

However, when the scale of the mechanical system is extremely small, or when the positioning device is used alone, the control device is not mounted in the control panel as described above but placed on a desk, for example. May be used.

In such a case, it is preferable that the wiring connection to the control device and the operation of the control device can be performed from the same direction. Also, when the positioning device is operated for a test or experiment, it is necessary to change the wiring connection to the control device frequently, so that the wiring connection surface should be on the same side as the operation panel surface for work efficiency. It is extremely important for improvement.

However, in the above-described conventional control device, since the wiring connection surface and the operation panel surface are on the opposite sides, whether the operator moves between the front side and the back side for the wiring connection or the operation. , Or the control device has to be moved, and its operation and wiring connection work are extremely inconvenient.

It is conceivable that the wiring connection surface and the operation panel surface are provided on the same surface. However, if this is done, this time the wiring connection surface will come to the front when installed in the control panel, so the duct Placement and wiring is not easy,
In addition, a large number of wires are exposed on the front surface of the control panel, which causes a problem that the appearance is impaired.

In view of the above problems, it is an object of the present invention to provide a control device capable of easily performing wiring connection work and operation according to the usage state of the control device.

[0010]

In order to solve the above-mentioned problems, a control device according to the invention of claim 1 has a rectangular parallelepiped case, and an electric circuit component for control is housed in the case. In the control device, the case includes an upper lid portion including an upper surface, a part of a front surface continuous with the upper surface, and a part of a back surface continuous with the upper surface, and the front lid and the back surface of the upper lid portion are inverted. It has a main body part that can be attached in any state that is not inverted or inverted, and an operation panel surface for operating the control device is formed on the front surface or the back surface of the upper lid part, A wiring connection surface for connecting wiring to the control device is formed on the back surface of the main body.

A control device according to a second aspect of the present invention is for controlling a positioning device for positioning a position of a load in a linear direction according to a rotation speed of an electric motor, and the positioning device is provided on the operation panel surface. A connector for connecting a teaching box for teaching the device is provided and configured.

In a control device according to a third aspect of the present invention, a connector for connecting wiring to the positioning device is provided on the wiring connection surface. In this specification, the front surface, the back surface, the upper surface, and the like do not represent absolute positions in the case, but represent relative positional relationships between the respective surfaces in the case. Therefore, whether the surface with the case is the front surface or the back surface,
In addition, it is possible to subjectively arbitrarily determine whether the surface is the top surface, the bottom surface, or the side surface.

[0013]

When the upper lid part is attached to the main body part in an inverted state, the operation panel surface and the wiring connection surface are located on the opposite surfaces, so that, for example, the control device is installed in the control panel for use. In this case, it is advantageous in connection with wiring.

Further, when the upper lid is attached to the main body without being turned over, the operation panel surface and the wiring connection surface are located on the same surface. Therefore, for example, when the control device is used alone, It is advantageous regarding wiring connection and operation.

As described above, the operation panel surface and the wiring connection surface can be easily selected to be the same surface or the opposite surface depending on the usage state or purpose of use of the control device.

A portion 32a above the front surface 32 of the upper lid portion 21
And the upper part 33a of the rear surface 33 have the same vertical length, and therefore the front surface 32 is rotated by 180 degrees about the vertical axis from the state shown in FIG.
Even when the back surface and the back surface 33 are reversed,
It can be attached to the main body portion 22.

An operation panel surface 51 for operating the control device 1 is formed on the rear surface 33 of the upper lid portion 21. The operation panel surface 51 includes a panel plate 52, a connector 53 attached to the panel plate 52, an indicator lamp 54, and a key switch 55.

The connector 53 is for transmitting and receiving a signal to and from a teaching box for teaching the positioning device. This teaching box is provided with, for example, a display panel composed of an LCD and a plurality of key switches, and can move a load positioned by a positioning device so that the position and order of the load can be remembered. ,
The positioning device can be controlled as so taught.

The indicator lamp 54 is for turning on / off the power source, operating,
It is for displaying an alarm or the like, and is composed of, for example, light emitting diodes of different colors. Also,
The key switch 55 is for resetting an alarm or the like.

The operation panel surface 5 is provided on the back surface of the panel plate 52.
1. A printed circuit board 56 for interfacing to 1 is attached, and a control electric wire 13 such as a flat cable connected to the electric circuit component 12 of the main body 22 is connected to the printed circuit board 56 with a margin. .

The panel plate 52 is attached by a screw 58 so as to close the rectangular hole 39 provided on the back surface 33. A battery case 57 accommodating a battery for backing up a memory provided in the control device 1 is attached to the printed board 56, and the panel board 5 is attached.
