Description

  The present invention relates to a measuring instrument for measuring the usage of a system under test, and a printing method for the measuring instrument.

  So-called measuring instruments for measuring the usage of electricity, gas, water, etc. are used for price transactions between users and operators of electricity, gas, water, etc., so it is necessary to ensure their fairness. is there. There are two types of systems to ensure this fairness: the type approval system and the verification system. The type approval system is a system in which a test specified by the Measurement Act is conducted by a third-party accredited organization, and if it conforms to technical standards, a type approval number is given and it is approved that it can be used as a measuring instrument for transactions. is there. In addition, the verification system is a system that approves that a type of measuring instrument that has received type approval is legally tested for each unit after manufacturing, and if it passes, it can be used as a measuring instrument for trading. The two systems ensure that the measuring instrument is fair.

  By the way, measuring instruments that pass the legal test in the certification system are required to display the certification display items. The label is required to display a standard conformity certification that indicates that the certification test has been passed, and a certification expiry date that represents the period during which the certification is approved. Attached by the designated manufacturer who obtained. In general, this indication is affixed to a measuring instrument completed as a test label after the test.

In addition, there are measuring instruments in which the display content of the test label is engraved on the main body, and printed measuring instruments (for example, Patent Document 1).

Cover up etc.

Reference numeral 105 denotes a transparent window made of glass or the like, which protects the inside of the measuring instrument and makes display items on the display unit 103 and the nameplate 104 visible from the outside.

  Reference numeral 106a denotes a test seal, which is composed of a film-like member such as a resin and displays a test display item.

FIG. 2 shows the structure of the test seal 106a. Reference numeral 201 denotes an adhesive made of a rubber-based transparent adhesive or the like, and is provided outside the expiration date printing field of the test seal 106 a and fixes the test seal 106 a to the transparent window 105. That is, the test seal 106 a has the adhesive 201 on the front side surface and is attached from the inside of the transparent window 105 with the adhesive.

Reference numeral 202 denotes a standard conformity mark, which is provided on the surface of the verification seal 106a and proves that the measuring instrument has passed the verification test.

Reference numeral 203 denotes an expiration date printing field, which is provided on the surface of the certification seal 106a, and prints the date and time of the certification expiration date, which represents the date allowed to be used after passing the certification test. The In addition, since the year / month display 205 indicating the expiration date of the certification is printed after the certification test, the expiration date printing column 203 is not printed at the stage of attaching the certification seal 106a to the transparent window 105 at the time of assembly.

Reference numeral 204 denotes a vent hole for circulating air on the front and back surfaces of the test seal. The temperature of the test seal 106a that has received the laser beam during printing rises. Then, the air between the test seal 106a and the transparent window 105 expands. This expanded air escapes through the vent 204 to the back side of the verification seal 106a and prevents the verification seal from expanding.

  Next, the operation of this embodiment will be described with reference to FIG.

FIG. 3 shows a printing facility for performing printing on the measuring instrument. Reference numeral 301 denotes a main body of a measuring instrument that has passed the verification test, which includes a watt-hour meter, a gas meter, a water meter, and the like. This example represents a watt hour meter. A laser engraving machine 302 is constituted by a laser oscillator or the like, emits laser light, and prints the year and month in the expiration date printing column of the verification seal 106a. Reference numeral 303 denotes a personal computer that controls printing operations such as printing items for the laser marking machine 302.

  The measuring instrument main body 301 is assembled before the verification test, and the verification label 106a is attached from the inside of the transparent window 105 at the time of the assembly. At this time, the expiration date printing field 203 of the verification label 106a is not printed. This is to avoid the inconvenience of giving a printed verification seal that proves that a measuring instrument that has failed a verification test performed after assembly can be used for transactions. On the other hand, for a measuring instrument that has passed and passed the verification test, the casing 101 is opened again and a verification label on which the verification expiration date is entered is pasted inside the transparent window where the test is performed on the finished product. That is not allowed. This is because it is not possible to ensure that predetermined performance such as insulation performance is satisfied if the casing 101 of the measuring instrument is opened again after the verification test.

The measuring instrument that has passed the verification test is printed by the laser stamping machine 302 on the verification seal 106a through the transparent window 105 that is fixed to the casing, and the necessary items such as the year / month display 205 are printed on the expiration date printing field 203. Since the transparent window 105 is transparent and transmits a laser beam, the test seal 106a can be printed by a laser engraving machine. As a result, the certification seal 106a forms a completed certification label indicating that it has passed the certification and may be used for trading.

  In the test label 106 a, the adhesive 201 is provided outside the expiration date printing field 203. The pressure-sensitive adhesive 201 is a transparent adhesive or the like. However, if the pressure-sensitive adhesive 201 is placed on the expiration date printing field 203, the pressure-sensitive adhesive 201 is also printed by printing with a laser engraving machine. The pressure-sensitive adhesive 201 is not suitable for printing, and causes bleeding and blurring of printing. If the present embodiment is used, since the adhesive 201 is not present in the expiration date printing field 203 where laser engraving is performed, it is possible to print directly on the test seal 106a and to perform high-quality printing with less blurring and blurring. .

The vent hole 204 allows air on the front and back surfaces of the test seal to flow. The temperature of the test seal 106a that has received the laser beam during printing rises. Then, the air between the test seal 106a and the transparent window 105 expands. This expanded air escapes through the vent 204 to the back side of the verification seal 106a and prevents the verification seal from expanding.

  As described above, by using the present embodiment, it is possible to provide a measuring instrument and a test display item printing method that prevent the test display items from being removed or becoming difficult to see due to dirt. In addition, since printing is performed on a measuring instrument that has passed the verification test, there is no inconvenience of giving a completed verification seal to the measuring instrument that has failed the verification test to prove that it can be used for transactions. . In addition, it is possible to ensure the performance during the verification test because the measuring instrument that has completed the verification test is not opened again and a verification seal is not affixed.

  A second embodiment of a measuring instrument according to the present invention will be described with reference to FIG. About each part of this Example 2, the same part as each part of the measuring instrument of Example 1 shown in FIG. 1 is shown with the same code | symbol.

  The difference between the second embodiment and the first embodiment is that, in the first embodiment, the test seal 106a is pasted on the transparent window 105, whereas in the second embodiment, the test seal 106b is pasted on the nameplate 104. is there.

A measuring instrument that has passed the verification test is stamped by the laser marking machine 302 on the expiration date printing field 203 of the verification label 106b, such as the year / month display 205, through the transparent window 105 fixed to the casing. As a result, the certification seal 106b forms a completed certification label indicating that it has passed the certification and may be used for trading.

Further, in FIG. 4, the verification seal 106b is affixed to the nameplate 104. However, the same matters as the verification seal are entered on the nameplate 104, and the date and time are measured with a laser stamp on the nameplate 104 after the end of the verification test of the measuring instrument. Necessary items to be displayed can be printed. The measuring instrument may be overhauled and used again after the expiry date. In this case, printing is performed on the nameplate 104 at the end of the first verification test, the verification seal 106b is pasted on the verification description items on the nameplate 104 at the second overhaul, and printing is performed by the laser engraving machine 302 at the end of the verification test. This is convenient because it eliminates the trouble of peeling off the verification seal for the first verification test.

  As described above, by using the present embodiment, it is possible to provide a measuring instrument and a test display item printing method that prevent the test display items from being removed or becoming difficult to see due to dirt.
