Description

  The present invention relates to a production management monitor that is mounted on a machine facility such as a processing machine in a production line, and displays a comparison between a signal obtained from the machine facility and a reference value input in advance to the production management monitor. .

As a means of knowing the operation status of machine equipment in production line equipment, the equipment is equipped with a signal tower that can be lit in multiple colors at the top of the equipment, and the equipment is in operation or stopped depending on the color of the lamp to be lit. However, it is impossible to confirm whether or not a standard value determined by a production plan or the like is satisfied.

  In particular, in the case of a machine facility that does not have an NC device, since it does not have a totaling function such as the number of processing, processing time, and operation rate, it is difficult to determine on the spot whether the reference value is satisfied.

Even in the machine equipment having the NC device, there was no method other than the operator going to each machine and operating the operation panel for confirmation.

  An object of the present invention is to provide an inexpensive and lightweight production management monitor capable of easily confirming a production status with respect to a predetermined reference value such as a production plan even from a place away from mechanical equipment.

As a means for solving the above-described problems, the present invention provides an operation unit for inputting a reference value of a mechanical facility, a liquid crystal display for displaying an input reference value and an input signal from the mechanical facility, and a machine A light source capable of emitting light in multiple colors and a translucent rod-shaped resin for diffusing the light emitted from the light source on the top of the production management monitor body with a CPU that performs comparative analysis of equipment reference values and input signals from machine equipment Is arranged to enable confirmation from all directions.

The light source is composed of LEDs capable of emitting a plurality of colors.

By providing a bar-shaped indicator lamp that displays the production status with respect to a predetermined reference value such as a production plan, etc. on the upper part of the production monitor arranged above the machine equipment, It is now possible to check the production status even from a remote location where the display of the production management monitor cannot be seen.

  By using a translucent rod-shaped resin capable of diffusing light in the display unit and using a light emitting source of the display unit with LEDs capable of emitting multiple colors, a single display unit can display multiple colors. As a result, it has become possible to provide a device that is more compact and less expensive than conventional display units configured by stacking light emitting units of a plurality of colors.

  Further, by adopting an LED capable of emitting a plurality of colors as a light source, it is possible to prevent a decrease in visibility due to the influence of external light.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the production management monitor of the present embodiment includes a main body operation unit for inputting a reference value determined in advance such as a production plan, and a main body composed of a liquid crystal display for displaying input data. The display unit is made of a translucent bar-like resin that is disposed on the top of the main body and is capable of diffusing light using LEDs capable of emitting multiple colors as a light source.

A microcomputer CPU is mounted inside the main body, and a reference value input from the main body operation unit is input and stored in the internal memory of the CPU.

In addition to the reference value input from the main unit operation unit, a signal from the machine facility is input to the CPU via the input interface unit to the main body and compared with the reference value of the machine facility stored in the memory. Done.

In the CPU, the value obtained by comparing the reference value of the mechanical equipment and the signal from the mechanical equipment can be assigned the emission color of the LED according to the value.

By using a three-color light emitting LED as a light emitting source and enabling light emission of a plurality of colors, an apparatus configuration capable of assigning various conditions is obtained.

Corresponding to the value obtained by comparing the reference value of the mechanical equipment and the signal from the mechanical equipment, the emitted LED light is not transmitted by the translucent rod-shaped resin that is disposed above the LED and can diffuse the light. It is spread so that it can be recognized from all directions.

The above production management monitor is intended to be mounted on machinery used on the production line, but the production management monitor of the present invention is not limited to use on the production line, but can be used for various devices. Can be done.
