Technical field

The present invention relates to an environment-friendly update from an existing control unit that is difficult to obtain to an existing control unit that can be obtained.

Background art

[0002] When an existing control unit such as a processing control device breaks down, parts are usually replaced to perform maintenance or renewal of the calorie control device (see Patent Document 1).

Patent Document 1: JP-A-2000-333324

[0003] However, when some of the components within the existing control unit that have failed are difficult to obtain, repair is no longer possible. In this case, the available control units will be used. In this case, a mounting base that matches the current control unit, not just the current control unit, will be manufactured.Furthermore, a special cable with a special connector, a motor that can be driven by the current control unit, or signal conversion will be required. The target interface was manufactured and updated with the current control unit.

FIG. 5 to FIG. 7 are diagrams for explaining the conventional updating method.

FIG. 5 is an example of a control unit to which the present invention is applied. (A) is a perspective view of an existing control unit, and (b) is a perspective view of a current control unit.

In FIG. 5 (a), reference numeral 110 denotes an existing control unit having components that are no longer available, and 110a denotes a power supply terminal unit (hereinafter, referred to as a “power supply terminal unit”) that receives power from a customer and supplies power to the motor. ), 110b is a control signal connector for controlling the control unit 110, and 11 Oc is a pulse signal connector for receiving a rotation pulse signal of the motor.

FIG. 6 is a block diagram of customer machine equipment using the existing control unit 110 of FIG. 5 (a). In the figure, reference numeral 700 denotes a customer machine, which includes an existing control unit 110, a motor 500, and a customer machine / control unit interface 600. The existing control unit 110 is provided with the above-mentioned power supply terminal 110a, control signal connector 110b, and pulse signal connector 11Oc, and the motor 500 has a pulse generator 5 for detecting rotation information of the motor. There are ten.

The motor 500 and the pulse generator 510 are provided with connector portions 500a and 510a, respectively. Cables 401-404 are connected between these parts. Reference numeral 401 denotes a power cable section for connecting the power supply terminal section 110a to the customer machine equipment 'control unit interface 600, and 402, a control signal cable section for connecting the control signal connector section 110b to the customer machine equipment and control unit interface 600. Reference numeral 403 denotes a motor drive cable portion that connects the power supply terminal portion 110a and the motor connector portion 50a, and 404 denotes a motor rotation pulse cable portion that connects the pulse signal connector portion 110c and the pulse generator connector portion 510a. Therefore, when the existing control unit 110 breaks down, the spare control unit 110 is replaced with the spare control unit 110, if any. I had to use it.

FIG. 5B shows a current control unit 210.

210a is a power supply terminal section, 210b is a control signal connector section, and 210c is a pulse signal connector section. As compared with the existing control unit 110 in FIG. 5A, although each component corresponds to each other, their dimensions and functions are different. Therefore, the current control unit 210 cannot be replaced with the existing control unit 110 shown in FIG. 6, and as shown in FIG. 7, a mounting base adapted to the current control unit 210 is manufactured, and furthermore, a dedicated connector is provided. We manufactured special cables, replaced motors that can be driven by the current control unit, or manufactured interfaces for signal conversion.

FIG. 7 is a block diagram of customer machine equipment using the current control unit 210 of FIG. 5 (b). In the figure, 700 ′ is a customer machine, which includes a current control unit 210 and a dedicated motor 500, and a dedicated interface 600 for the customer machine and a control unit! Then, a power cable section 401 ′ connecting the power supply terminal section 210 a to the customer machine equipment “control unit interface 600”, and a control signal connecting the control signal connector section 210 b to the customer machine facility / control unit interface 600. The cable section 402, the motor drive cable section 403 'connecting the power terminal section 210a and the motor connector section 500a', and the pulse signal cable section 404 'connecting the pulse signal connector section 21 Oc and the pulse generator connector section 510a' are also provided. Each is a dedicated cable section. In this way, it is not only necessary to obtain (or manufacture) the current control unit, but also to manufacture a mounting base tailored to the current control unit, and also to manufacture a dedicated cable having a dedicated connector, replace a drivable motor, or An interface for signal conversion was also manufactured and updated with the current control unit.

Then, the failed control unit 110 was discarded together with other components.

[0008] As described above, the update of an existing control unit having components that are difficult to obtain has conventionally required the production of a mounting base, a dedicated cable, and an interface unit that can be connected only with a control unit. Preparation time and work time for renewal were increased, resulting in increased costs for parts to be prepared and increased industrial waste for existing parts.
