Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
First, the structure and principle of the cooling device according to the embodiment will be described with reference to FIGS. 1, 2, and 7 schematically represented.
As shown in FIG. 7, in this cooling device 15, one end is connected to a cooling gas supply source and the other end is closed, and the cooling device 15 is a pipe having a plurality of holes 17 formed at intervals in the longitudinal direction. The main body is the part 16. In this configuration, when cooling air is supplied from one end, the air volume of the cooling gas injected from each hole 17 is not constant depending on various conditions such as the inner diameter of the pipe portion 16 and the inner diameter of the hole 17, and FIG. 7 shows. As shown by the arrow, the inventor of the present application has found that the air volume of the cooling gas blown out from the holes 17 gradually increases from the upstream to the downstream, and the air volume for each hole 17 may not be constant. Therefore, even if the cooling device 15 using only the pipe portion 16 having such a structure is provided in the housing of the inspection device, it is considered difficult to always uniformly and efficiently cool the inside of the housing.

Therefore, in the cooling device 15 of the embodiment, the hole 17 for which the air volume is to be increased is selected from the plurality of holes 17 formed in the pipe portion 16, and the hole 17 adjacent to the hole 17 toward the downstream side is selected. An adjusting member was inserted into the pipe portion 16 and placed inside the pipe portion 16 to partially close the inside of the pipe portion 16.

As shown in FIG. 1, when the adjusting member 18 is arranged in the second hole 17 counting from one end (right side in the figure) on the supply side of the cooling gas, this hole is as can be seen from the comparison with FIG. The air volume from the hole 17 adjacent to the hole 17 on the upstream side of 17 increases. The air volume from the hole 17 adjacent to the hole 17 on the downstream side of the hole 17 in which the adjusting member 18 is arranged is slightly smaller than that in the case where the adjusting member 18 is not provided, but the air volume from the other holes 17 on the downstream side is shown in FIG. There was no significant change in comparison, and as a whole, the air volume from each hole 17 in FIG. 1 was averaged more than in the state shown in FIG.

As shown in FIG. 2, when the adjusting member 18 is arranged in the second and fourth holes 17 from one end on the cooling gas supply side, these holes can be seen from the comparison with FIG. The air volume from the two holes 17 adjacent to each other on the upstream side of 17 increases. The air volume from the most downstream holes 17 is not significantly different from that in FIG. 7 without the adjusting member 18, and as a whole, the air volume from each hole 17 in FIG. 4 is averager than the state shown in FIG. It has become more uniform than the state shown in FIG.

When the adjusting member 18 is attached in this way, the air volume of the cooling gas injected from the adjacent hole 17 on the upstream side of the hole 17 in which the adjusting member 18 is provided, that is, the adjacent hole 17 on the one end side of the pipe portion 16 is increased. The air volume of the cooling gas that is increased and injected from each of the plurality of holes 17 is made more uniform than before the adjusting member 18 is provided.

Therefore, if this cooling device is appropriately arranged in the partitioned space to be cooled, the space can be efficiently cooled. Further, if there is a part in this space that generates a particularly high amount of heat as a cooling target, or a part whose allowable temperature is set lower than other parts for some reason, the specific hole 17 should face the part or the like. If the pipe portion 16 is arranged in the hole 17 and the adjusting member 18 is provided in the other hole 17 one downstream of the specific hole 17, the cooling gas can be intensively applied to the component or the like to cool the component particularly efficiently. can.

Next, an embodiment of the present invention will be described in more detail with reference to FIGS. 3 to 6.

As shown in FIG. 3, the inspection device 1 of the present embodiment has a box-shaped housing 2 supported on the installation surface by the legs 3. Inside the lower part of the housing 2, a belt conveyor type transport unit 4 is provided so that both ends project from the openings 2a and 2b provided on both the left and right side surfaces, respectively. An inspection unit 5 is provided inside the upper part of the housing 2, and the inspected object W transported in the housing 2 can be inspected by the transport unit 4. The inspection principle and inspection purpose of the inspected object W by the inspection unit 5 are not limited, and the type of the inspected object W is not particularly limited. Further, the inspection unit 5 shall include a control unit that controls the entire inspection device.

As shown in FIG. 3, the inspection device 1 includes a cooling device 15 inside the upper part of the housing 2. The cooling device 15 is arranged above the inspection unit 5. The cooling device 15 has a pipe portion 16 having one end connected to a cooling gas supply source (not shown) via a conduit 6 and the other end closed. A plurality of holes 17 are formed in the pipe portion 16 at intervals in the longitudinal direction thereof, but the plurality of holes 17 are located at the same position in the circumferential direction of the pipe portion 16 and are located directly above in FIG. Therefore, it does not appear in FIG.

4 to 6 are views showing an example of the form of the cooling device 15 provided in the inspection device 1 of the embodiment shown in FIG. In each of the views of FIGS. 4 to 6, each segment (a) is a plan view seen from the direction of the arrow (a) of FIG. 3, and each segment (b) is a diagram of each segment (a). A cross-sectional view taken along the aa cutting line, and each segmented view (c) is a cross-sectional view taken along the cc cutting line of each segmented diagram (b).

FIG. 4 is a diagram showing a first structural example of the cooling device 15 in the embodiment. As shown in FIG. 4, a plurality of round holes 17a are formed on the peripheral surface of the pipe portion 16 at intervals in the longitudinal direction. The plurality of round holes 17a are arranged at predetermined intervals in the longitudinal direction (axial direction) of the pipe portion 16, and the positions in the circumferential direction are also the same. However, the positions of the plurality of round holes 17a in the circumferential direction can be appropriately set in consideration of the cooling effect inside the housing 2. That is, the plurality of round holes 17a arranged in the axial direction may be arranged at any position in the circumferential direction as long as it is necessary to achieve the purpose of cooling in the housing 2. To exemplify the dimensions of the pipe portion 16, the inner diameter is 9.8 mm, the outer diameter is 13.8 mm, the wall thickness is 2 mm, and the round hole 17a has a diameter of 4 mm.

The pin 18a has a solid cylindrical shape that can be inserted into the round hole 17a without a gap, and its length is slightly smaller than the outer diameter of the pipe portion 16. When the pin 18a is inserted into the round hole 17a and abutted against the inner peripheral surface, the upper end portion Is substantially the same as the outer peripheral surface of the pipe portion 16. As described above with reference to FIGS. 1 and 2, the two round holes 17a (the rightmost round hole 17a in FIG. 4) on one end side are compared with the case where the pin 18a is not provided. The air volume of is increased.

As shown in FIG. 3, in the inspection device 1, the pipe portion 16 is provided directly above the inspection portion 5, and other parts and the like are not shown around the pipe portion 16. However, as illustrated in FIG. 4, a pin 18a is provided in the second round hole 17a from the one end side of the pipe portion 16, and in the housing 2, the circle on the upstream side (one end side) thereof. If a specific component or the like is provided in front of the hole 17a, a cooling gas having an increased air volume is blown onto the component or the like, so that a high cooling effect can be obtained. That is, when there is a component or the like that is particularly desired to be cooled in the housing 2 of the inspection device 1 as shown in FIG. 3, the pipe portion 16 is arranged so that the round hole 17a faces the component or the like, and downstream thereof. A pin 18a may be provided in the round hole 17a on the side (the other end side).

When the pin 18a is provided in the second round hole 17a from the one end side as shown in FIG. 4, or as described in the principle with reference to FIG. 2, the two or more round holes 17a are appropriately spaced apart from each other. When the pin 18a is provided, the injection state of the cooling air from the round hole 17a becomes uniform as compared with the case where the adjusting member 18 described with reference to FIG. 7 is not provided. When the air in the housing 2 of the inspection device 1 is warmed, the warm air tends to collect in the upper position in the housing 2, so that the air is as uniform as possible from the many round holes 17a of the pipe portion 16. By blowing out the cooling gas upward, the air inside the housing 2 is evenly agitated, and the inside of the housing 2 can be efficiently cooled.

If the dimensional relationship between the round pin 18a and the round hole 17a can be inserted and removed, the position of the pin 18a can be changed according to the model of the inspection device 1 in which the calorific value and position of the parts to be cooled are different. can. However, the pin 18a and the round hole 17a may have a structure in which the pin 18a and the round hole 17a are fixed by welding after press fitting or insertion in order to prevent them from falling off.

FIG. 5 is a diagram showing a second structural example of the cooling device 15 in the embodiment. In this structural example, the hole of the pipe portion 16 is a screw hole 17b, and the adjusting member is a screw 18b. According to this structural example, by adjusting the degree of insertion of the screw 18b into the screw hole 17b, the degree of the screw 18b closing the inside of the pipe portion 16 can be adjusted, and the cooling gas blown out from the screw hole 17b can be adjusted. The air volume can be set to the desired state.

FIG. 6 is a diagram showing a third structural example of the cooling device 15 in the embodiment. In this structural example, the hole of the pipe portion 16 is a slit 17c, and the adjusting member is a plate material 18c. According to this structural example, it is easy to process the slit 18c on the pipe portion 16, and it is also easy to prepare a plate material 18c suitable for the dimensions of the slit 17c.

As the cooling gas, compressed air of a compressor easily available at a factory or the like can be used. That is, the cooling gas does not necessarily mean a specially low-temperature gas prepared for cooling, but may be a gas having a temperature that can be used for cooling in relation to the temperature of the object to be cooled.

Further, in the embodiment described above, the pipe portion 16 of the cooling device 15 is a round pipe, but the shape is not particularly limited as long as it is a member having a hollow longitudinal shape.
