Description

  The present invention relates to a sensor mounting jig. For example, when a food and drink sealed in a soft packaging container is sterilized using a retort sterilizer, a temperature sensor is inserted into the food or drink sealed in a soft packaging container in order to sterilize the food and drink as expected. Then, the temperature of the food and drink being sterilized is measured. In this case, in order to reliably sterilize the food and drink as expected, it is not sufficient to simply insert a temperature sensor into the food and drink sealed in the soft packaging container. It is necessary to correctly set the detection part of the temperature sensor at a position where the latest product temperature can be measured. Such a setting operation is necessary for each batch for sterilizing food and drink sealed in a soft packaging container using a retort sterilization apparatus, requires considerable skill, and uses nerves. Therefore, in order to make the setting operation as easy as possible, a mounting jig for setting the temperature sensor is used. A pressure sensor is used to measure the pressure in the soft packaging container during sterilization. In this case, a mounting jig may be used in the same manner. Regarding improvement.

  Conventionally, as the sensor mounting jig as described above, a plan view as shown in FIG. 12 is used. The conventional sensor mounting jig 16 shown in FIG. 12 is a temperature sensor mounting jig, which has a through-hole 36 in the radial direction in the center of a relatively short cylindrical member, and also has an axial direction. The screw members 46a and 46b are attached to both end faces of the lens. The sensor mounting jig 16 is used as follows. First, the sensor mounting jig 16 is placed in a flexible packaging container, and screw members 46a and 46b on both end faces are taken out through the flexible packaging container, and are usually mounted by tightening nuts via O-rings. Similarly, the screw member of the temperature sensor base is taken out through the flexible packaging container, and is usually attached thereto by tightening a nut via an O-ring. Since the packing for sealing is attached to the through hole of the screw member of the temperature sensor base, the flexible packaging container is filled with food and drink, and the flexible packaging container is sealed. Next, the temperature sensor is passed through the screw member at the base of the temperature sensor to penetrate the flexible packaging container. Finally, in the flexible packaging container in which the food or drink is sealed, the detection portion of the temperature sensor is passed through the through hole 36 of the sensor mounting jig 16 and the tip is exposed at a predetermined position in the food or drink. Thus, with the assistance of the sensor mounting jig, the temperature sensor detector was correctly set at a position where the latest product temperature of the food and drink sealed in the soft packaging container could be measured, and sealed in many other soft packaging containers. The retort sterilizer is loaded with food and drink and sterilized. Meanwhile, in order to reliably sterilize the food and drink as expected, the temperature of the food and drink sealed in the flexible packaging container is continuously measured with the temperature sensor.

  However, the conventional sensor mounting jig 16 as described above has a problem that it is very troublesome to pass the sensor detection portion through the through hole 36 in the central portion. In the case of the conventional sensor mounting jig 16, the slant guide portion 26 that guides the sensor detection portion to the central through hole 36 is small, so that it takes time to pass the sensor detection portion through the through hole 36. Not only does it actually pass, but it is often sterilized by the illusion that it has passed, and in some cases, the detection part of the sensor may be damaged. This is likely to occur when an opaque viscous food or drink is sealed in a soft packaging container.

  The problem to be solved by the present invention is that the detection part of the sensor can be easily and reliably passed through the through hole in the central part, that is, the detection part of the sensor can be easily placed at a predetermined position of the food or drink sealed in the flexible packaging container. It is another object of the present invention to provide a sensor mounting jig that can be reliably and correctly set.

  The present invention that solves the above-described problems includes a guide body having a shape in which the surface side descends as a whole from the peripheral portion toward the center portion, a through hole formed in the center portion of the guide body, and the guide body And a screw member attached to both side surface portions at a position sandwiching the through hole from both sides, and a sensor mounting jig configured to pass the detection portion of the sensor through the through hole.

  The sensor mounting jig according to the present invention includes a guide body, a through hole, and a screw member. The guide body is formed in a shape in which the surface side descends as a whole from the peripheral portion toward the central portion. The through hole is formed at the center of the guide body. The screw member is attached to both side surface portions of the guide body at a position sandwiching the through hole from both sides.

  In the sensor mounting jig according to the present invention, the surface side of the guide body has a shape that descends as a whole from the peripheral portion toward the central portion as described above. A shape that descends stepwise toward the center, a shape that descends into a curved surface such as a convex or concave shape from the periphery to the center, and a shape that descends into a linear inclined surface from the periphery to the center The shape etc. which combined these arbitrarily are included. Especially, it is preferable to form the surface side of the guide body into an inclined surface and / or a curved surface that descends smoothly from the peripheral portion toward the center portion, and specifically, a funnel shape, a reverse arch shape, and a parabolic shape. It is preferable to form in a simple shape. No matter what part of the guide body the sensor's detection unit tip hits, the detection unit's front end naturally follows the shape of the surface side that descends from the peripheral edge of the guide unit toward the central unit and into the through hole in the central unit. The sensor is guided to pass the detection part of the sensor through the through hole.

  In the sensor mounting jig according to the present invention, the shape of the side surface portion of the guide body may be any of a square shape, a circular shape, an oval shape, or the like as a whole as viewed from above, but among the side surface portions of the guide body. It is preferable that both side surface portions which are in a positional relationship sandwiching the through hole from both sides are formed in parallel planes, and a screw member is attached thereto. When the sensor mounting jig is put in the flexible packaging container, the screw members on both sides are taken out through the flexible packaging container, and usually attached to the flexible packaging container by tightening the nut through an O-ring. This is because the position of the sensor mounting jig is easy and easy to mount, and when it is mounted as described above, the gap between the flexible packaging container and the sensor mounting jig can be reliably sealed.

  In the sensor mounting jig according to the present invention, the material of the guide body and the screw member is not particularly limited, but in terms of lightness and durability, particularly heat resistance, epoxy resin, phenol resin, polyimide resin, polyether ether ketone, Further, those integrally molded with heat-resistant plastics such as these reinforced resins are preferable. The dimensions are not particularly limited, but for example, a temperature sensor having an outer diameter of 1.4 mm and a length of 45 mm is mounted in a standard square pouch container having an outer dimension of 295 mm × 217 mm. When using them as jigs, the outer diameter of the guide body is 25 to 28 mm, the depth is 7 mm, the inner diameter of the through hole is 2 mm, the length is 3 mm, and the length of the screw member is 5 mm. can do.

  According to the sensor mounting jig according to the present invention, it is possible to easily and reliably set the sensor detection unit at a predetermined position of the food or drink sealed in the flexible packaging container.
