図7に示すように、この冷却装置15は、一端部が冷却気体の供給源に接続されるとともに他端部は閉止され、長手方向に間隔をおいて形成された複数の孔17を有する管部16を本体としている。この構成において、一端部から冷却空気を供給すると、管部16の内径や孔17の内径等の諸条件によっては、各孔17から噴射される冷却気体の風量が一定にならず、図7に矢印で示すように、上流から下流に向かうに従って孔17から吹き出す冷却気体の風量が徐々に大きくなっていき、各孔17ごとの風量が一定にならない場合があることを本願発明者は見出した。従って、このような構造の管部16のみによる冷却装置15を検査装置の筐体内に設けても、筐体内を常に均一かつ効率的に冷却することは困難であると考えられる。
Embodiments of the present invention will be specifically described below 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, the cooling device 15 is a tube having a plurality of holes 17 that are connected at one end to a cooling gas supply source and closed at the other end, and are spaced apart in the longitudinal direction. The part 16 is the main body. 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. As indicated by the arrows, 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 upstream to downstream, and the air volume for each hole 17 may not be constant. Therefore, even if the cooling device 15 having only the tube portion 16 having such a structure is provided in the casing of the inspection apparatus, it is considered difficult to always uniformly and efficiently cool the inside of the casing.

そこで、実施形態の冷却装置15では、管部16に形成された複数の孔17のうち、風量を増やしたい孔17を選択し、その孔17よりも下流側に向けて一つ隣の孔17に調節部材を挿入して管部16内に配置し、管部16の内部を部分的に塞ぐこととした。   Therefore, in the cooling device 15 of the embodiment, the hole 17 for which the air volume is to be increased is selected from among the plurality of holes 17 formed in the pipe portion 16, and the hole 17 that is adjacent to the hole 17 is arranged downstream from the hole 17. The adjustment member was inserted into the tube portion 16 and placed in the tube portion 16 to partially close the inside of the tube portion 16.

図1に示すように、冷却気体の供給側である一端部(図中右側)から数えて2個目の孔17に調節部材18を配置すると、図7との比較から分かるように、この孔17よりも上流側に一つ隣の孔17からの風量が増加する。調節部材18を配置した孔17よりも下流側に一つ隣の孔17からの風量は調節部材18がない場合よりもやや少なくなるが、その他の下流側の孔17からの風量は図7と比べて大きな変化はなく、全体として見れば、図1における各孔17からの風量は、図7に示す状態よりも平均化している。   As shown in FIG. 1, when the adjusting member 18 is arranged in the second hole 17 counted from one end (the right side in the figure) that is the cooling gas supply side, as shown in the comparison with FIG. The air volume from the next adjacent hole 17 increases upstream from the 17. The air volume from the hole 17 immediately adjacent to the downstream side of the hole 17 where the adjusting member 18 is arranged is slightly smaller than that without the adjusting member 18, but the air volume from the other downstream holes 17 is as shown in FIG. Compared with the whole, the air volume from each hole 17 in FIG. 1 is averaged more than the state shown in FIG.

図2に示すように、冷却気体の供給側である一端部から2個目と4個目の2つの孔17に調節部材18を配置すると、図7との比較から分かるように、これらの孔17よりも上流側の一つ隣にある二つの孔17からの風量がそれぞれ増加する。最下流の孔17からの風量は調節部材18がない図7の場合と比べて大きな違いはなく、全体として見れば、図4における各孔17からの風量は、図7に示す状態よりも平均化しており、図1に示す状態よりもさらに均一になっている。   As shown in FIG. 2, when adjusting members 18 are arranged in the second and fourth holes 17 from one end on the cooling gas supply side, as shown in a comparison with FIG. The air volume from the two holes 17 adjacent to the upstream side of 17 increases. The air volume from the most downstream hole 17 is not significantly different from that in the case of FIG. 7 without the adjusting member 18, and as a whole, the air volume from each hole 17 in FIG. It is more uniform than the state shown in FIG.

このように調節部材18を取り付けると、調節部材18を設けた孔17よりも上流側の隣の孔17、すなわち管部16の一端部側の隣の孔17から噴射される冷却気体の風量が増加し、複数の孔17からそれぞれ噴射される冷却気体の風量は、調節部材18を設ける前よりも均一化される。   When the adjustment 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 provided with the adjustment member 18, that is, the adjacent hole 17 on the one end side of the tube 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 adjustment member 18 is provided.

従って、冷却対象である区画された空間内にこの冷却装置を適切に配置すれば、空間内を効率的に冷却することができる。また、この空間内に冷却対象として特に発熱が高い部品等や、何らかの理由で他の部品よりも許容温度が低く設定されている部品等があれば、特定の孔17が当該部品等に向くように管部16を配置し、特定の孔17の一つ下流の他の孔17に調節部材18を設ければ、当該部品等に冷却気体を集中的に当てて特に効率的に冷却することができる。   Therefore, if the cooling device is appropriately arranged in the partitioned space to be cooled, the space can be efficiently cooled. In addition, if there is a part with particularly high heat generation as a cooling target in this space, or a part whose allowable temperature is set lower than other parts for some reason, the specific hole 17 faces the part. If the adjustment member 18 is provided in the other hole 17 downstream of the specific hole 17, the cooling gas can be applied to the part or the like in a concentrated manner to cool particularly efficiently. it can.

次に、本発明の実施形態を図3〜図6を参照してさらに具体的に説明する。
図3は実施形態の冷却装置が設けられた検査装置1を示す模式的な断面図である。図3に示すように、本実施形態の検査装置1は、脚部3で設置面上に支持された箱型の筐体2を有している。筐体2の下部の内部には、左右両側面にそれぞれ設けられた開口2a,2bから両端が突出するようにベルトコンベア式の搬送部4が設けられている。筐体2の上部の内部には、検査部5が設けられており、搬送部4によって筐体2内を搬送される被検査物Wを検査することができる。なお、検査部5による被検査物Wの検査原理及び検査目的等は問わないし、被検査物Wの種類も特に限定しない。さらに、検査部5は、本検査装置の全体を制御する制御部を含むものとする。
Next, the embodiment of the present invention will be described more specifically with reference to FIGS.
FIG. 3 is a schematic cross-sectional view showing the inspection apparatus 1 provided with the cooling device of the embodiment. As shown in FIG. 3, the inspection apparatus 1 according to the present embodiment includes 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 protrude from openings 2 a and 2 b provided on the left and right side surfaces, respectively. An inspection unit 5 is provided inside the upper portion of the housing 2, and the inspection object W transported in the housing 2 by the transport unit 4 can be inspected. The inspection principle and inspection purpose of the inspection object W by the inspection unit 5 are not limited, and the type of the inspection object W is not particularly limited. Further, the inspection unit 5 includes a control unit that controls the entire inspection apparatus.

図3に示すように、検査装置1は、筐体2の上部の内部に冷却装置15を備えている。冷却装置15は検査部5の上方に配置されている。冷却装置15は、一端部が冷却気体の供給源(図示せず)に導管6を介して接続され、他端部が閉止された管部16を有する。管部16は、その長手方向に間隔をおいて複数の孔17が形成されているが、複数の孔17は管部16の周方向について同一の位置にあり、図3では真上の位置にあるため図3には表れない。   As shown in FIG. 3, the inspection device 1 includes a cooling device 15 inside the upper portion of the housing 2. The cooling device 15 is disposed 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. The tube portion 16 is formed with a plurality of holes 17 at intervals in the longitudinal direction, but the plurality of holes 17 are at the same position in the circumferential direction of the tube portion 16, and in FIG. Therefore, it does not appear in FIG.

図4から図6は、図3に示す実施形態の検査装置1に設けられた冷却装置15の形態例を示す図である。図4から図6の各図において、各分図(a)が、図3の矢視(a)の方向から見た平面図であり、各分図(b)は各分図(a)のa−a切断線での断面図、各分図(c)は各分図(b)のc−c切断線での断面図である。   4-6 is a figure which shows the example of the form of the cooling device 15 provided in the test | inspection apparatus 1 of embodiment shown in FIG. 4 to 6, each partial view (a) is a plan view seen from the direction of arrow (a) in FIG. 3, and each partial view (b) is a view of each partial view (a). A sectional view taken along a line aa, and each partial view (c) are sectional views taken along a line cc in FIG.

図4は、実施形態における冷却装置15の第1の構造例を示す図である。図4に示すように、管部16の周面には、長手方向に間隔をおいて複数の丸孔17aが形成されている。複数の丸孔17aは、管部16の長手方向(軸方向)については所定間隔で配置されており、周方向に関する位置も同一である。しかしながら、複数の丸孔17aの周方向に関する位置は、筐体2の内部における冷却効果を考慮して適宜に設定することができる。すなわち、軸方向に並んでいる複数の丸孔17aは、筐体2内における冷却の目的を達成するために必要な限り、周方向についてはどの位置に配置してもよい。なお、管部16の寸法を例示すると、内径9.8mm、外径13.8mm、肉厚2mmであり、丸孔17aは直径が4mmである。   FIG. 4 is a diagram illustrating a first structure example of the cooling device 15 according to the embodiment. As shown in FIG. 4, a plurality of round holes 17 a are formed on the circumferential 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 tube portion 16, and the positions in the circumferential direction are also the same. However, the positions of the plurality of round holes 17 a 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 necessary to achieve the purpose of cooling in the housing 2. For example, the dimensions of the tube portion 16 are an inner diameter of 9.8 mm, an outer diameter of 13.8 mm, and a wall thickness of 2 mm, and the round hole 17a has a diameter of 4 mm.

図4に例示するように、一端部側から2個目の丸孔17aには、調節部材18としてのピン18aが設けられている。ピン18aは、丸孔17aに隙間無く挿入できる中実の円柱形状であり、長さは管部16の外径よりもやや小さく、丸孔17aに挿入して内周面に突き当てると上端部が管部16の外周面と略同一面になる。先に図1及び図2を参照して原理を説明したように、ピン18aを設けない場合に比べ、一端部側にある2個の丸孔17a(図4において最も右側の丸孔17a)からの風量は増大する。   As illustrated in FIG. 4, a pin 18 a as an adjustment member 18 is provided in the second round hole 17 a from one end side. The pin 18a has a solid cylindrical shape that can be inserted into the round hole 17a without any gap. The length of the pin 18a is slightly smaller than the outer diameter of the tube portion 16, and the upper end portion is inserted into the round hole 17a and abuts against the inner peripheral surface. Is substantially flush with the outer peripheral surface of the tube portion 16. As described above with reference to FIGS. 1 and 2, the two round holes 17a on the one end side (the rightmost round hole 17a in FIG. 4) are compared with the case where the pin 18a is not provided. The air volume increases.

図3に示すように、この検査装置1においては、管部16は検査部5の真上に設けられており、管部16の周囲には特にその他の部品等は図示していない。しかしながら、図4に例示したように、管部16の一端部側から2個目の丸孔17aにピン18aが設けられており、筐体2内では、その上流側(一端部側)の丸孔17aの正面に特定の部品等が設けられているとすれば、当該部品等には風量が増大した冷却気体が吹き付けるので、高い冷却効果が得られる。すなわち、図3に示すような検査装置1の筐体2内において、特に冷却したい部品等がある場合には、当該部品等に丸孔17aが対面するように管部16を配置し、その下流側(他端部側)の丸孔17aにピン18aを設ければよい。   As shown in FIG. 3, in this inspection apparatus 1, the pipe portion 16 is provided directly above the inspection portion 5, and other components and the like are not particularly shown around the pipe portion 16. However, as illustrated in FIG. 4, the pin 18 a is provided in the second round hole 17 a from the one end side of the tube portion 16, and the upstream side (one end side) of the casing 2 has a round shape. If a specific part or the like is provided in front of the hole 17a, a cooling gas having an increased air volume is blown onto the part or the like, so that a high cooling effect is obtained. That is, in the case 2 of the inspection apparatus 1 as shown in FIG. 3, when there is a part or the like to be cooled in particular, the pipe part 16 is arranged so that the round hole 17a faces the part or the like, and the downstream side thereof. What is necessary is just to provide the pin 18a in the round hole 17a of the side (other end part side).

図4に示すように一端部側から2個目の丸孔17aにピン18aを設けた場合、または図2を参照して原理を説明したように、2個以上の丸孔17aに適宜間隔でピン18aを設けた場合には、図7を参照して説明した調節部材18を設けない場合に比べ、丸孔17aからの冷却空気の噴射状態が均一化する。検査装置1の筐体2内の空気が温められた場合、温かい空気は筐体2内の上方の位置に溜まり易いので、管部16の多くの丸孔17aから可及的に均一な状態で冷却気体を上方へ吹き出すことにより、筐体2内の空気が満遍なく攪拌され、筐体2内を効率よく冷却することができる。   As shown in FIG. 4, when the pin 18a is provided in the second round hole 17a from one end side, or as described in the principle with reference to FIG. 2, the two or more round holes 17a are appropriately spaced. When the pin 18a is provided, the cooling air injection state 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 accumulate at an upper position in the housing 2, so that the air can be as uniform as possible from the many round holes 17 a of the pipe portion 16. By blowing the cooling gas upward, the air in the housing 2 is evenly stirred, and the inside of the housing 2 can be efficiently cooled.

なお、丸いピン18aと丸孔17aの寸法関係が挿抜可能なものであれば、冷却すべき部品の発熱量や位置等が異なる検査装置1の機種に対応してピン18aの位置を変えることができる。しかしながら、ピン18aと丸孔17aは、脱落の防止のために圧入又は挿入後の溶接で固定する構造でもよい。   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 in accordance with the type of the inspection apparatus 1 in which the heat generation amount and position of the component to be cooled are different. it can. However, the pin 18a and the round hole 17a may be configured to be fixed by press-fitting or welding after insertion in order to prevent dropping.

図5は、実施形態における冷却装置15の第2の構造例を示す図である。この構造例では、管部16の孔がねじ孔17bであり、調節部材がねじ18bである。この構造例によれば、ねじ孔17bに対するねじ18bの挿入の程度を調節することにより、ねじ18bが管部16の内部を閉塞する程度を調節することができ、ねじ孔17bから吹き出す冷却気体の風量を所望の状態に設定することができる   FIG. 5 is a diagram illustrating a second structure example of the cooling device 15 according to the embodiment. In this structural example, the hole of the pipe part 16 is the screw hole 17b, and the adjustment member is the screw 18b. According to this structural example, by adjusting the degree of insertion of the screw 18b into the screw hole 17b, the degree to which the screw 18b closes 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

図6は、実施形態における冷却装置15の第3の構造例を示す図である。この構造例では、管部16の孔がスリット17cであり、調節部材が板材18cである。この構造例によれば、管部16に対するスリット18cの加工は容易であり、スリット17cの寸法に適合した板材18cを用意することも容易である。   FIG. 6 is a diagram illustrating a third structure example of the cooling device 15 according to the embodiment. In this structural example, the hole of the pipe part 16 is the slit 17c, and the adjusting member is the plate member 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 that matches the size of the slit 17c.

なお、冷却気体としては、工場などで容易に入手できるコンプレッサの圧縮空気を利用することができる。すなわち、冷却気体とは、必ずしも冷却用として準備した特別に低温の気体との意味ではなく、冷却対象の温度との関係で冷却に利用しうる温度の気体であればよい。   In addition, as cooling gas, the compressed air of the compressor which can be easily obtained in a factory etc. can be utilized. That is, the cooling gas does not necessarily mean a specially low temperature gas prepared for cooling, and may be a gas having a temperature that can be used for cooling in relation to the temperature of the cooling target.

また、以上説明した実施形態では、冷却装置15の管部16は丸管であったが、中空長手形状の部材であれば、特に形状を限定するものではない。   In the embodiment described above, the tube portion 16 of the cooling device 15 is a round tube, but the shape is not particularly limited as long as it is a hollow longitudinal member.
