Description

Written book Transport surface temperature measurement system

The present invention relates to a technology of a surface temperature measurement system for a conveyed product, and more specifically, an area that is controlled to be separated to a predetermined temperature, a conveyance unit that conveys a conveyed product in the area, and a conveyance in the area The present invention relates to the technology of a surface measurement system for a surface, which has a temperature measuring means for measuring the temperature of the object. Background thigh

Conventionally, a transported object (work) such as an automobile body is formed in a press process and then welded in a body welding process, and then sent to a coating process to repeatedly apply a predetermined coating ¾ ^. . In such a coating process, the object to be conveyed is subjected to pretreatment, electrodeposition coating, etc., and then continuously or intermittently in an area where the temperature is controlled to be a predetermined temperature by a conveying conveyor as a conveying means. It is brought in.

Specifically, in the painting process, the above-described area is divided into a painting area and a drying area, and the thigh is moved between the areas and is repeatedly painted and ¾t. Usually, the work is once painted and then thighed, and then the wrinkles and corrections are made, and then the paint (upper layer) is applied again. In the painting area, the transported material is painted by the painting equipment while stopped or moved. The drying area is controlled so as to be fixed, and the conveyed product can be transported inside the soot area. And done.

By the way, in the above-described coating process, the (surface) S measuring system is provided with a¾ measuring means for measuring the atmosphere in the area, and within the area measured by the measuring means. Based on the atmosphere ffi, the thigh crossing was measured indirectly.

For example, Japanese Patent Laid-Open No. 5-2 1 2 3 2 6 discloses a configuration in which a sensor for measuring the inside of a paint area is provided as a temperature measurement system for a conveyed product. Based on the temperature in the area measured by the temperature sensor, it is controlled so that painting is performed under conditions by a painting device provided in the painting area. Conventionally, in the above-described temperature measurement system for a conveyed product in the painting process, a temperature measuring unit for measuring the surface temperature of the conveyed product is provided in the area, and the surface temperature of the object is directly measured by the temperature measuring unit. The structure for measuring the distance is well known.

For example, Japanese Laid-Open Patent Publication No. 10-2 3 9 1 5 6 discloses a non-contact radio as a temperature measuring means for measuring the surface temperature of an object in a coating area as a measurement system for a conveyed object. The color variation of the product of the coated steel sheet is controlled by feedback control of the thigh's heel based on the surface heel of the thigh measured by such radio. Is done.

As a temperature measurement system for transported objects, as disclosed in the above-mentioned Japanese Patent Laid-Open No. 5-2 1 2 3 2 6, the temperature of the thigh is measured by measuring the atmosphere in the area. In the measurement configuration, it is not possible to directly measure the transported object. Therefore, in order to adjust the control in the area and the actual size of the thigh, the dummy thigh is taken out and a thermocouple, etc. It was necessary to measure the temperature of the conveyed product using a temperature sensor. for that reason, It was impossible to measure the heel of all thighs, and the quality of the transported goods was inferior due to the fact that the transported goods were likely to vary.

On the other hand, in the transported object wrinkle measurement system disclosed in Japanese Patent Laid-Open No. 10-2 3 9 1 5 6 described above, the surface temperature of the transported object is directly measured by using a non-contact type thermometer. Because the temperature can be measured automatically, the temperature measurement of all transported objects becomes the J ability, and the quality assurance of the transported goods can be improved.

However, non-hate-type meters such as free ff meters are inferior in metaphysics, so it is preferable to place them in the area under an environment where the area is controlled to a certain level, such as in an area. On the other hand, if a non-male type measuring instrument is placed outside the area, the surface of the thigh cannot be accurately measured due to adhesion of dust or the like in the area to the sensor or lens. There was a problem.

Accordingly, the present invention relates to a thigh surface wrinkle measurement system, which solves the above-mentioned problem of ¾έ¾, and enables measurement of all thighs while improving surface measurement accuracy, and The purpose is to provide a surface temperature measurement system for transported goods with improved quality assurance.

As described above, according to the first aspect of the present invention, it is possible to improve the quality assurance of the conveyed product by improving the measurement accuracy of the surface temperature while enabling the temperature measurement of the entire product.

In particular, the air filling path is provided with a tubular member protruding from the ridge of the area, and it is preferable that an air supply / exhaust path for supplying and discharging dehumidified air into the tubular member is connected to the tubular member. That's right. With this configuration, it is possible to supply and discharge clean soot air in the air filling path and further increase the measurement accuracy of the thigh surface.

In addition, it is preferable that one end of the air filling path is opened toward the inner side of the area, and the other end is attached with an infrared transparent glass film. By configuring in this way, the soot air supplied to the air filling path is discharged into the area, thereby effectively preventing the air and dust in the area from entering the air filling path. In addition, the glass member can effectively prevent the dust in the area from adhering to the non-contact type thermometer.

The second aspect of the present invention includes position detection means for detecting a current position of the thigh within the area, and the position detection means detects that the conveyed object has been moved to a fixed position. Then, the surface temperature of the object is measured by the temperature measuring means.
