Description

本発明は、張力を付与した状態で搬送される連続帯状の被検査物にX線を照射して、被検査物を透過した透過X線のX線透過量に基づいてこの被検査物の品質(外観、割れ欠け、異物混入の有無など)を検査するX線検査装置に係り、詳細には、検査部におけるX線検出手段と被検査物の距離を常に一定に保持するX線検査装置に関する。   The present invention irradiates X-rays to a continuous belt-like inspection object conveyed in a tensioned state, and the quality of the inspection object based on the amount of X-ray transmission of transmitted X-rays transmitted through the inspection object. The present invention relates to an X-ray inspection apparatus that inspects (external appearance, cracks, presence of foreign matter, etc.), and more particularly, to an X-ray inspection apparatus that always keeps the distance between the X-ray detection means and the inspection object in the inspection section constant. .

図7には、連続帯状の被検査物にX線を照射して、被検査物を透過した透過X線のX線透過量に基づいてこの被検査物の品質(外観、割れ欠け、異物混入の有無など)を検査するX線検査装置を示している。図7に示すように、連続帯状の被検査物Wの品質検査に特化したX線検査装置100は、複数の搬送用ローラ102を有する搬送手段101を備えている。搬送手段101では、被検査物Wを複数の搬送用ローラ102に掛け回すように取り付けて、取り付けた被検査物Wを所定の張力を付与しながら複数の搬送用ローラ102を回転させて、それぞれの搬送用ローラ102,102の間の所定の搬送方向Yに搬送する。また、X線検査装置100は、搬送手段101となる所定位置に配置された一対の搬送用ローラ102,102の間に配置されたX線検査手段103を備えている。X線検査手段103は、X線を照射するX線照射手段104と、X線を検出するX線検出手段105とを備えている。X線照射手段104とX線検出手段105は、一対の搬送用ローラ102,102の間の被検査物Wを挟んで対向して配置されており、X線照射手段104とX線検出手段105の間が検査部106となる。X線検査手段103では、X線照射手段104から照射されて被検査物Wを透過した透過X線をX線検出手段105で検出して、そのX線透過量に基づいて被検査物Wを検査する。   FIG. 7 shows the quality of the inspection object (appearance, crack chipping, foreign matter mixing) based on the X-ray transmission amount of the transmitted X-ray transmitted through the inspection object by irradiating the continuous belt-shaped inspection object with X-rays. 2 shows an X-ray inspection apparatus for inspecting the presence or absence of such as. As shown in FIG. 7, an X-ray inspection apparatus 100 specialized for quality inspection of a continuous strip-shaped object W includes a transport unit 101 having a plurality of transport rollers 102. In the conveying means 101, the inspection object W is attached so as to hang around the plurality of conveying rollers 102, and the plurality of conveying rollers 102 are rotated while applying a predetermined tension to the attached inspection object W, respectively. Are transported in a predetermined transport direction Y between the transport rollers 102, 102. In addition, the X-ray inspection apparatus 100 includes an X-ray inspection unit 103 disposed between a pair of transport rollers 102 and 102 disposed at a predetermined position as the transport unit 101. The X-ray inspection unit 103 includes an X-ray irradiation unit 104 that emits X-rays and an X-ray detection unit 105 that detects X-rays. The X-ray irradiation unit 104 and the X-ray detection unit 105 are disposed to face each other with the inspection object W between the pair of transfer rollers 102 and 102 therebetween. The X-ray irradiation unit 104 and the X-ray detection unit 105 are disposed. Between these is the inspection unit 106. In the X-ray inspection means 103, the transmitted X-rays irradiated from the X-ray irradiation means 104 and transmitted through the inspection object W are detected by the X-ray detection means 105, and the inspection object W is detected based on the X-ray transmission amount. inspect.

なお、上述したX線検査装置100は、主にPTP包装機に組み込まれるものである。したがって、図8(a)に示すように、連続帯状の被検査物Wとしては、PTPシート110の各ポケット部113に錠剤114などが充填されたものである。図8(b)に示すように、PTPシート110は、錠剤114などが充填されるポケット部113を有する樹脂製の包装用フィルム111と、包装用フィルム111にポケット部113の開口側を密閉するように取り付けられたアルミニウム製のカバーフィルム112とからなる。   The X-ray inspection apparatus 100 described above is mainly incorporated into a PTP packaging machine. Therefore, as shown in FIG. 8A, the continuous strip-shaped inspection object W is one in which the pockets 113 of the PTP sheet 110 are filled with tablets 114 and the like. As shown in FIG. 8B, the PTP sheet 110 seals the opening side of the pocket portion 113 to the packaging film 111 and the resin packaging film 111 having the pocket portions 113 filled with the tablets 114 and the like. The cover film 112 made of aluminum is attached.

PTP包装機では、その製造工程中に、ポケット部113に錠剤114などが充填された後、錠剤114などの外観や割れ欠けなどを検査する工程を備えている。上述したX線検査装置100は、このような検査工程のために組み込まれたものである。   In the PTP packaging machine, the manufacturing process includes a step of inspecting the appearance, cracks, and the like of the tablet 114 after the tablet 114 is filled in the pocket portion 113. The X-ray inspection apparatus 100 described above is incorporated for such an inspection process.

また、PTP包装機は、検査工程の後に検査済みの被検査物W(PTPシート110)を所定長さに切断する工程を備えている。例えば、下記特許文献1に開示される切断装置などは、連続帯状の被検査物Wを切断するためにPTP包装機に組み込まれるものとして好適なものである。   Further, the PTP packaging machine includes a step of cutting the inspected object W (PTP sheet 110) that has been inspected into a predetermined length after the inspection step. For example, the cutting device disclosed in the following Patent Document 1 is suitable as one incorporated into a PTP packaging machine in order to cut a continuous strip-shaped inspection object W.

特開2006−282267号公報JP 2006-282267 A

しかしながら、切断装置による被検査物Wの切断工程においては、切断時にそれまでの連続搬送を間欠搬送に切り換えるなどしており、そのため、振動が発生するという問題があった。特に連続帯状の被検査物Wの場合は全体的に所定の張力を付与しながら搬送するため、その振動が前段の検査工程、すなわち、X線検査装置100による検査に影響するようになる。具体的には、X線検査装置100では、X線照射手段104とX線検出手段105の間に形成された検査部106において、被検査物Wがその厚さ方向(図7の搬送方向Yと直交する方向)に振動する。被検査物Wがこのように振動すると、検査時にX線検出手段105と被検査物Wの距離が安定しないことから、X線透過画像に誤差が生じていまい、正しい検査結果が得られない。切断工程の他、複数の搬送用ローラ102の配置関係などが正しくない場合などにも振動が発生する。   However, in the cutting process of the object W to be inspected by the cutting device, the continuous conveyance up to that time is switched to intermittent conveyance at the time of cutting, which causes a problem that vibration occurs. In particular, in the case of the continuous strip-shaped inspection object W, since it is conveyed while applying a predetermined tension as a whole, the vibration affects the previous inspection process, that is, the inspection by the X-ray inspection apparatus 100. Specifically, in the X-ray inspection apparatus 100, in the inspection unit 106 formed between the X-ray irradiation unit 104 and the X-ray detection unit 105, the inspection object W is in the thickness direction (conveying direction Y in FIG. 7). Vibrates in the direction orthogonal to When the inspection object W vibrates in this way, the distance between the X-ray detection means 105 and the inspection object W is not stable at the time of inspection, so that an error occurs in the X-ray transmission image and a correct inspection result cannot be obtained. In addition to the cutting process, vibration also occurs when the arrangement relationship of the plurality of conveying rollers 102 is not correct.

本発明は、上記状況に鑑みてなされたものであり、X線照射手段とX線検出手段の間の検査部において、X線検出手段と連続帯状の被検査物の距離が一定となるようにこの被検査物を支持することで、安定した検査結果が得られるX線検査装置を提供することを目的としている。   The present invention has been made in view of the above situation, and in the inspection section between the X-ray irradiation means and the X-ray detection means, the distance between the X-ray detection means and the continuous strip-like object is constant. An object of the present invention is to provide an X-ray inspection apparatus capable of obtaining a stable inspection result by supporting the object to be inspected.

次に、上記の課題を解決するための手段を、実施の形態に対応する図面を参照して説明する。

図1に示すように、X線検査装置1(1A)は、検査部7の近傍における被検査物Wの一方の面側に支持手段10を備えている。すなわち、支持手段10は、被検査物WのX線発生器5と対向する面側に、このX線発生器5と被検査物Wの間に介在するように設けられている。
From here, the structure in the vicinity of the inspection unit 7 described above, which is the gist of the present invention, will be described for each embodiment.
“First Embodiment”
As shown in FIG. 1, the X-ray inspection apparatus 1 (1 </ b> A) includes support means 10 on one surface side of the inspection object W in the vicinity of the inspection unit 7. That is, the support means 10 is provided on the surface of the inspection object W facing the X-ray generator 5 so as to be interposed between the X-ray generator 5 and the inspection object W.

支持手段10は、検査部7において、X線検出器6と搬送される被検査物Wの距離が一定となるようにこの被検査物Wを支持するために設けられたものであり、一対のローラ11,11と、ローラ11,11に掛け回された循環ベルト12と、循環ベルト12のベルト面に突出して設けられた複数の円筒部からなる吸着手段13とを備えている。吸着手段13は、その吸着口13aから空気を吸い込むことにより被検査物Wを吸着口13aに吸着させるものである。   The support means 10 is provided to support the inspection object W so that the distance between the X-ray detector 6 and the inspection object W to be conveyed is constant in the inspection unit 7. The rollers 11, 11, the circulation belt 12 wound around the rollers 11, 11, and the suction means 13 including a plurality of cylindrical portions provided to protrude from the belt surface of the circulation belt 12. The suction means 13 sucks air from the suction port 13a to cause the inspection object W to be sucked to the suction port 13a.

図2に示すように、吸着手段13を構成する複数の円筒部は、循環ベルト12の循環方向に沿って並んで列をなして設けられるとともに、循環ベルト12の幅方向に2列となるように設けられている。また、各列の円筒部は、その吸着口13aが検査部7における被検査物Wの所定の検査領域8外に位置するように設けられている。この実施形態では、被検査物Wの搬送方向Yと直交する幅方向の中央部を検査領域8としているため、幅方向の両端部が検査領域8外となる。   As shown in FIG. 2, the plurality of cylindrical portions constituting the adsorbing means 13 are provided side by side along the circulation direction of the circulation belt 12 and are arranged in two rows in the width direction of the circulation belt 12. Is provided. Further, the cylindrical portions of each row are provided so that the suction ports 13 a are located outside the predetermined inspection region 8 of the inspection object W in the inspection portion 7. In this embodiment, since the central portion in the width direction orthogonal to the conveyance direction Y of the inspection object W is used as the inspection region 8, both end portions in the width direction are outside the inspection region 8.

また、一対のローラ11,11は、循環ベルト12を被検査物Wの搬送速度と略等速となるように循環させている。したがって、吸着手段13は、被検査物Wの搬送速度と略等速で搬送方向Yに移動する。そのため、検査部7において、吸着手段13は、被検査物Wに吸着口13aを当接させて被検査物Wを一方の面側からこの吸着口13aに吸着させても、互いの速度差により吸着が解除されるなど不具合が生じたり、被検査物Wの搬送に支障が生じるたりするようなことはない。   Further, the pair of rollers 11 and 11 circulate the circulation belt 12 so as to be substantially the same speed as the conveyance speed of the inspection object W. Accordingly, the suction means 13 moves in the transport direction Y at a speed substantially equal to the transport speed of the inspection object W. Therefore, in the inspection unit 7, even if the suction unit 13 causes the suction port 13 a to contact the inspection object W and causes the inspection object W to be suctioned to the suction port 13 a from one surface side, due to the speed difference between them. There will be no troubles such as release of suction, or troubles in transporting the inspection object W.

上述した第1実施形態によれば、被検査物Wは、吸着手段13によって吸着されて一方の面側へと変位しようとするが、吸着手段13の吸着口13aに当接していることで厚さ方向の変位が規制されるため、その位置、すなわち、吸着口13aに当接した位置で安定してX線検出器6との距離が一定に保持されるようになる。このとき、上述したように、吸着手段13が被検査物Wの搬送速度と略等速で搬送方向Yへと移動するため、被検査物Wの搬送に支障が生じることはない。   According to the first embodiment described above, the inspection object W is attracted by the suction means 13 and tends to be displaced to one surface side, but is thicker by being in contact with the suction port 13a of the suction means 13. Since the displacement in the vertical direction is regulated, the distance from the X-ray detector 6 is stably maintained at that position, that is, the position in contact with the suction port 13a. At this time, as described above, since the suction means 13 moves in the transport direction Y at a speed substantially equal to the transport speed of the inspection object W, there is no problem in the transport of the inspection object W.

そして、X線発生器5とX線検出器6の間に形成された検査部7において、X線検出器6と被検査物Wの距離が常に一定に保持されるため、X線透過画像に誤差などが生じなくなり、安定した検査結果を得ることができる。   In the inspection unit 7 formed between the X-ray generator 5 and the X-ray detector 6, the distance between the X-ray detector 6 and the object W to be inspected is always kept constant. An error or the like does not occur, and a stable inspection result can be obtained.

「第2実施形態」
図3に示すように、X線検査装置1(1B)は、検査部7の近傍における被検査物Wの一方の面側に支持手段20を備えている。すなわち、上述した第1実施形態と同様、支持手段20は、被検査物WのX線発生器5と対向する面側に、このX線発生器5と被検査物Wの間に介在するように設けられている。なお、第2実施形態において、上述した第1実施形態と同等又は同一の箇所には同一の符号を付し、その説明は省略する。
