Abstract

PURPOSE:To detect an abnormal state and abnormal contents in a position remote from the equipment of an abnormality generating source and to rapidly executing a maintenance processing for canceling the abnormal state by changing a signal detecting the abnormal state to a radio wave signal and transferring to an alarm such as an abnormality display board, an abnormal radio wave receiver. CONSTITUTION:The abnormal operation of the equipment 1 is detected and inputted to a radio wave transmitter 6 as a detecting signal. In the radio wave transmitter 6, based on the inputted detecting signal, the abnormal state and the abnormal contents are converted to the radio wave signal. Then, the radio wave signal 7 is fed to the alarm such as the abnormality display board 5 or the abnormal radio wave receiver 9 through a radio equipment 8. Thereby, abnormal information can be collected at any time and at any place, loss in labor and time for searching a man is saved and rapidly reset to a normal state.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an equipment abnormality information transmission device that notifies abnormal operation of various equipment such as machine tools and presses located in a factory.

[Conventional technology]

When an abnormality occurs in a factory where various types of industrial machinery are arranged, the abnormal condition is reported to a maintenance person, a worker, etc. using an abnormality alarm, an abnormality warning light, etc.

FIG. 2 shows an installation with an abnormality warning light as an example of this. For example, when an abnormality occurs in equipment 1 such as a machine tool or a press, the abnormality is detected electrically and a warning light 2 is turned on. A maintenance person 1 worker, etc., sees the warning light 2 lit and detects that an abnormality has occurred in the equipment 1. In order to facilitate this detection, the brightness of the warning light 2 may be increased or a flashing warning light 2 may be used. Alternatively, instead of the warning light 2, an alarm device that emits an alarm sound may be attached.

Furthermore, FIG. 3 shows a system that makes it possible to detect the occurrence of an abnormality in equipment within the operation room.

In this case, a plurality of pieces of equipment 1 are connected by signal lines 3 to an abnormality display board 5 arranged in an operation room 4. By looking at the display on the abnormality display board 5, it is possible to detect which equipment 1 has experienced an abnormality.

[Problem that the invention seeks to solve]

However, in the case of Figure 2, in press factories, etc., the loud operating noise of the equipment may be a hindrance, and the alarm sound from the alarm may not be heard by maintenance personnel or workers, or may be hidden behind other machinery and equipment. The light from warning light 2 may not reach you. Also,
In the case of Figure 3, a maintenance person happens to be in operation room 4.

If a worker or the like is away from their seat, an abnormal state of the equipment 1 cannot be detected. For these reasons, conventional alarm devices are unable to detect abnormal conditions in the equipment 1.
There were often delays in maintenance procedures.

Therefore, the present invention is not constrained by the arrangement of various equipment, the arrangement of personnel in the operation room, etc.
The purpose is to quickly detect abnormal conditions and details of equipment.

[Means for solving problems]

In order to achieve the purpose, the equipment abnormality information transmission device of the present invention monitors the operating state of the equipment in operation, and is connected to an abnormality detection device that generates a detection signal when abnormal operation is detected. It is characterized by comprising a radio wave transmitting device that converts a signal into a radio wave signal and transmits the signal, and an alarm device that is placed apart from the equipment and receives the radio wave signal via a radio to recognize an abnormal state. .

〔Example〕

Hereinafter, with reference to FIG. 1, the features of the present invention will be specifically explained using examples.

The equipment abnormality information transmission device of this embodiment has an abnormality detection device (not shown) built into the equipment 1, such as a machine tool or a press, which is the source of the abnormality, and various abnormality signals can be taken out to the outside through contacts. It has become. A radio wave transmitting device 6 is connected to this abnormal signal contact via a signal line 3.

For example, in a machine tool, an abnormal state occurs when processing on a workpiece is completed or a tool is damaged.

Furthermore, in presses, various abnormal conditions occur due to malfunctions of material feeders, misfeeds, and the like.

The abnormality detection device detects such abnormal operation of the equipment 1 and manually sends it to the radio wave transmitting device 6 as a detection signal. The radio wave transmitting device 6 converts the manually generated detection signal into a radio signal corresponding to the abnormal state and the content of the abnormality. Then, the radio signal 7 is sent to an alarm device such as an abnormality display board 5 or an abnormality radio wave receiver 9 via a radio device 8.

As the radio device 8, one for simple business use, one for general business use, etc. is used. Since a system is adopted in which the abnormal condition is transmitted to the abnormality display board 5 or the abnormal radio wave receiver 9 via this radio device 8,
Abnormality information can be collected anytime and anywhere, eliminating the hassle and time wasted searching for people, and allowing for a quick return to normal conditions. Further, it is preferable to use the abnormality display board 5 or the abnormality radio wave receiver 9 that is equipped with a liquid crystal display, a buzzer, an abnormality location indicator lamp, etc., so that the details of the abnormality can be identified at a glance. Furthermore, when the abnormality display board 5 or the abnormality radio wave receiver 9 is miniaturized to be portable like a pager, it is possible to detect the occurrence of an abnormality in the equipment 1 and the contents of the abnormality even in a place far away from the equipment 1. can.

In addition, in the above example, the equipment l located in the factory
The case of detecting an abnormality has been explained. However, the present invention is not limited thereto, and can be similarly applied to, for example, general consumer electronics products and ancillary equipment of buildings.

〔Effect of the invention〕

As described above, in the present invention, a signal detecting an abnormal state is converted into a radio wave signal and transmitted to an alarm device such as an abnormality display board or an abnormal radio wave receiver. Therefore, even if the equipment is located far away from the equipment that is the source of the abnormality, it is possible to detect the abnormal state and the details of the abnormality, and it is possible to quickly perform maintenance processing to eliminate the abnormal state.

Furthermore, when the alarm device is made small and portable, it is no longer necessary to have a person in the operation room all the time, resulting in labor savings.
