Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a maintenance management panel, and particularly to a maintenance management panel suitable for daily maintenance management of factory equipment such as machine tools.

(Prior Art and Problems) In general, in factory equipment, etc., in order to operate the equipment normally, it is important to manage such things as daily equipment inspection and regular lubricant oil change. Conventionally, such management has been left to the operator's own control, and for example, daily inspections include checking whether oil pressure, R:In oil level, etc. are normal. After confirming this, the equipment was put into operation. For this reason, in the process of autonomous operation by operators, it is inevitable that equipment defects will be overlooked, causing equipment troubles. Also, depending on the equipment, it may be necessary to inspect it once a week. 11
Because there are many items that require inspection every hour, irregular inspection items, and long-term inspection items, inspections are often not performed reliably in equipment where operators often change. Ta.

[Purpose of the invention]

Therefore, the object of the present invention is to overcome the drawbacks of the above-mentioned prior art,
In order to ensure that daily and irregular inspections of equipment are carried out, equipment maintenance is carried out by indicating inspection items using lamps etc. when inspection is required, and displaying that inspections have been properly carried out. The purpose is to provide a maintenance management panel that allows management to be performed.

[Summary of the invention]

In order to achieve the above object, the present invention includes a plurality of first display means that display daily inspection items when the main power of the equipment is turned on, and a plurality of first display means that display daily inspection items when the main power of the equipment is turned on, and The present invention provides a maintenance management panel including at least one second display means for displaying inspection items.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view of a maintenance management panel according to an embodiment of the present invention. As shown in the figure, lamp X lights up when oil change is required, and lamp Y lights up when water draining is required, giving instructions for respective maintenance. On the other hand, lamps P, Q, R, and S indicate daily inspection items, and push buttons p and q are used to confirm inspection.
, r, and s to turn off the light.

FIG. 2 shows a wiring diagram of the maintenance management panel shown in FIG. 1, particularly illustrating the case where it is applied to a grinding machine.

A switch SW1 is provided for main opening/closing, and by pressing this switch, the relay M enters a self-holding operation and the main power is turned on. When the main power is turned on, relays B, D, F, H
is activated, and lamps P, Q, and R.

S lights up. As shown in Figure 1, the lamps P, Q, R, and S indicate items to be checked before starting work every day, such as "Is the oil pressure at a normal value?" and "Is the oil level at a normal value?" ” etc. will be displayed. The operator performs the required inspection according to the displayed items, and presses the push buttons p and q corresponding to the inspection displayed items to complete the inspection.

Press r, s. Push buttons p, q, r, s are relay A,
It has the function of self-holding operation of C, G, and F, and relay A
, C, G, and F, relays B and D correspond to the respective operations of
, F, and H are deactivated. As a result, the push button p,
In response to the operations of q, r, and s, lamps P, Q, R, and S are turned off. Therefore, by turning off the lamps P, Q, R, and S, it is possible to confirm that the inspection of the item in question has been completed.

On the other hand, the switch SW2 is a starting switch for the grinding machine T. That is, by turning on the switch SW2, the relay N enters a self-holding operation, and the grinding machine T is operated. At the same time, the hour meters v and W that count the accumulated time operate, and the operating time of the grinding machine T is accumulated. For example, hour meter V is ground! This is used to indicate when it is time to change the IT spindle lubricating oil.When the spindle rotates for a preset amount of time, the contact point of the hour meter (■) acts and relay I operates.

As a result, the lamp X connected to the contacts of the relay I lights up, and a display prompting oil change is made. On the other hand, the hour meter W
performs the same operation, and when the preset time comes, lights up the lamp Y to display the necessary information. The operator can take necessary action based on the indications of the lamps X and Y.

In this way, the display of lamps X and Y, and the lamp P.

By displaying Q, R, and S, the operator can reliably carry out daily start-up inspections and periodic inspections.

In the above embodiment, a grinder is used as an example of the equipment, but the present invention is not limited to this and can be implemented to inspect any item of any other equipment.

〔Effect of the invention〕

As described above, according to the present invention, maintenance management of equipment, which was conventionally left to the operator's own control, can be instructed through a lamp that lights up when the main power is turned on or a lamp that lights up based on the cumulative operating time. By doing or confirming,
Therefore, it is possible to obtain a maintenance management panel that can be carried out, prevents missing inspection items, forgotten inspections, etc., and has a great effect on equipment maintenance.

[Brief explanation of the drawing]

FIG. 1 is a perspective view of a maintenance management panel according to an embodiment of the present invention; FIG. 2 is a wiring diagram of the maintenance management panel shown in FIG. 1. P, Q, R, S, X, Y... lamp, p, Q, r.

Claims (1)

[Claims] 1. A plurality of first display means for displaying daily inspection items when the main power of the equipment is turned on, and corresponding to the operation of the equipment,
A maintenance management panel comprising at least one second display means for displaying inspection items every predetermined period of time. 2. The maintenance management panel as set forth in claim 1, comprising a plurality of confirmation means for individually erasing the first display means.
