Abstract

<P>PROBLEM TO BE SOLVED: To provide a tag device which enables a management object to be continuously identified by constituting the tag device so as to be hardly detached concurrently with replacement of the management object. <P>SOLUTION: An identification number for identifying a steam trap being a management object is stored to an electronic tag 2. The electronic tag 2 is connected to a fixture 5 via a charger 7. The charger 7 incorporates a voice generator and a character display unit. The main body 9 of the fixture 4 is integrated with the end of a thermoelectric generating element 3. The fixture 4 is composed of the main body 9 and a knob 10. When the fixture 4 is detached from a pipe 5 by pinching the knob 10, a caution not to detach is indicated by the voice generator and the character display section of the charger 7, so that the electronic tag 2 linked with the fixture 4 is prevented from being detached. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a tag device having an identification number for identifying a management object and attached to the management object itself or in the vicinity thereof. The tag device is used, for example, to identify a management object when maintaining and inspecting a management object such as valves and traps installed in various pipes or equipment of various plants.

  A conventional tag device includes a flat tag on which an identification number for identifying a management object is displayed or stored, and a thin wire-like fixture for attaching the flat tag to the management object itself or in the vicinity thereof. It is what has.

The conventional tag device (also referred to as a nameplate) is removed when the management object becomes old and is replaced with a new one, and this tag device is also removed along with the management object to be replaced and replaced. There was a problem that the object could not be identified. For example, when the management target is a steam trap, an identification number is required to periodically diagnose whether the steam trap is operating normally. ) Is often removed.
Japanese Patent Application Laid-Open No. 7-139995

  The problem to be solved is to provide a tag device that makes it difficult to remove the tag device at the same time when the management object is replaced or exchanged, and can continue to identify the management object.

  The present invention includes a tag on which an identification number for identifying a management object is displayed or stored, and a fixture for attaching the tag to or near the management object itself. An element and a sound generation unit or a character display unit are provided.

  According to the present invention, the tag generator is likely to be removed by driving the voice generation unit or the character display unit with the power generated by the thermoelectric generation unit by providing the thermoelectric generation unit and the voice generation unit or the character display unit together with the tag. Then, it is possible to generate a caution sound that prevents the tag device from being removed, or to display a caution character to prevent the tag device from being removed and to continue to identify the management object.

  In order to use the thermoelectric generator, the present invention is preferably attached to a portion having a predetermined amount of heat. For example, it is suitable for high-temperature fluid piping through which high-temperature steam or high-temperature water flows or high-temperature plant equipment. is there.

  As shown in FIG. 1, the tag device 1 of the present embodiment includes an electronic tag 2, a thermoelectric generator 3, and a fixture 4 that attaches one end of the thermoelectric generator 3 to a high-temperature steam pipe 5. A steam trap as an object is attached to the downstream part (right side part) of the pipe 5.

  The square thin plate-like electronic tag 2 stores in advance an identification number for identifying a steam trap as an object to be managed. A resin protective case for protecting the electronic tag 2 is provided on the outer periphery of the electronic tag 2.

The thermoelectric generator 3 is disposed in contact with the outer surface of the pipe 5. The right end portion of the thermoelectric generator 3 is formed integrally with the fixture 4. A heat radiating fin 6 is connected to the upper surface of the thermoelectric generator 3. The thermoelectric generator 3 is an element that generates electric power based on the heat of high-temperature steam or high-temperature condensate flowing down in the pipe 5, and can supply driving power to the charging unit 7 described later.

  The attachment 4 is a clip-like thing as a stationery, and includes a main body 9 made of a spring plate material that sandwiches the outer surface of the pipe 5, and a knob portion 10 that pushes the main body 9 when the main body 9 is attached to the pipe 5. The When the operator holds the knob portion 10 by hand and attaches the main body 9 to the pipe 5, the thermoelectric generator 3 and the charging section 7 are attached to the pipe 5 at the same time. The electronic tag 2 is attached below the charging unit 7 via the connecting cord 8. The vapor trap identification number stored in the electronic tag 2 is read by a tag reader (not shown) in a non-contact manner.

  The charging unit 7 includes a voice generation unit and a character display unit. Necessary character information is displayed on the display 11 in accordance with a signal from the character display unit. Each of the sound generation unit, the character display unit, and the display 11 uses a power source generated by the thermoelectric generator 3 for driving.

  A strain sensor for detecting the amount of deformation of the knob portion 10 is attached to the knob portion 10 of the fixture 4. When the operator grasps the knob portion 10 and tries to remove the fixture 4, the thermoelectric generator 3, and the electronic tag 2, the distortion sensor of the knob portion 10 detects the sound generation portion built in the charging portion 7. To generate a caution sound such as “Do not remove this tag device” or display or blink a similar caution character on the display 11.

  When a steam trap as a management object (not shown) attached to the right side of the pipe 5 is removed from the pipe 5 and replaced, when an operator tries to remove the fixture 4 at the same time, Since characters are emitted, the possibility that the electronic tag 2 connected to the fixture 4 is removed at the same time is low.

  In the present embodiment, an example in which a clip-like member having the knob portion 10 is used as the attachment 4 is shown. However, the attachment 4 can be a conventionally known attachment belt, and the surface condition of the management object Depending on the case, an adhesive tape or an adhesive may be used.

  Further, in this embodiment, an example in which an electronic tag is used as a tag is shown, but a conventionally known tag in which characters or symbols are written or pasted can also be used.
