DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a maintenance schedule monitoring device for a laser beam machine system, and more particularly, to a maintenance time monitoring device for informing the user that it is time to carry out a maintenance and inspection of all laser beam machine component elements requiring maintenance.
2. Background Art of the Related
A laser beam machine incorporates a relatively large number of component elements in the structure of the laser oscillator and the like thereof, which require a periodic maintenance and inspection.
In the laser beam machine, examples of the maintenance items and the component elements that require a periodic maintenance and inspection include a replacement of the lubricating oil of the vane pump of the cooling water supply system, a replacement of the lubricating oil of the Roots blower of the laser gas supply system, a replacement of the filter and the cooling water of the cooling water supply system, and an alignment of the bent mirror of the laser optical system, and the like.
Conventionally, the schedules for the above-mentioned periodic maintenance and inspection of the many component elements requiring maintenance are generally managed by entering the maintenance and inspection intervals and the dates of implementing the maintenance and inspection and the like in a maintenance data sheet or the like for each maintenance item of each object requiring maintenance, in accordance with the instructions given in a service manual or the like, or by pasting a label or the like, showing a maintenance and inspection schedule, on a machine.
The management of maintenance and inspection schedules described above depends entirely on the user, and as it is cumbersome, it often is not carried out properly. For example, merely pasting a label showing the maintenance and inspection interval onto a machine has little effect for reminding the user that it is time to carry out the maintenance and inspection, and as a result, the user often does not remember to implement the maintenance and inspection at the proper time.
SUMMARY OF THE INVENTION
The present invention is intended to solve the problems posed by the conventional management method for the maintenance and inspection schedules of a laser beam machine, and the object of the present invention is to provide a maintenance schedule monitoring device which is able to automatically and accurately notify the user that it is time to carry out the maintenance and inspection of an object requiring maintenance.
To fulfill the aforementioned object, a maintenance schedule monitoring device for a laser beam machine system is provided, which comprises a time measuring means (A) designed to measure the working time of an object requiring maintenance in response to information received on whether or not said object in the laser beam machine system is working, a time alarm means (B) designed to detect that said time measured by said time measuring means (A) has reached a preset time, and a maintenance schedule display control means (C) designed to issue an instruction for indicating that it is time to carry out a maintenance of said object requiring maintenance on a display means (D) when said time alarm means (B) detects that said maintenance time has reached said preset time.
In the maintenance schedule monitoring device for a laser beam machine system according to the present invention, said time measuring means (A) may be designed to measure the working time of said object to requiring maintenance, depending on the working condition of said object requiring maintenance.
Also, the maintenance schedule monitoring device for a laser beam machine system according to the present invention may be provided with an input means (E) whereby data and parameters related to the maintenance items and maintenance times of said object requiring maintenance are updated and entered as required.
Further, the maintenance schedule monitoring device for a laser beam machine system according to
