Description

スライドファスナー用スライダーの検査装置Slide fastener fastener inspection device
　本発明は、スライダー組立機で組み立てられたスライドファスナー用スライダーを検査する装置に関する。 The present invention relates to an apparatus for inspecting a slide fastener slider assembled by a slider assembly machine.
　スライドファスナー用のスライダーとして、例えば、特許文献１に開示された自動停止装置付きのスライダーが知られている。
　このスライダーは、図１及び図２に示すように、胴体１と、カバー２と、スプリング３と、引手４らの部品で構成されている。 As a slider for a slide fastener, for example, a slider with an automatic stop device disclosed in Patent Document 1 is known.
As shown in FIGS. 1 and 2, the slider is composed of a body 1, a cover 2, a spring 3, and a handle 4.
　胴体１は、上下方向に対向して配置された上翼板１０と下翼板１１と、上翼板１０と下翼板１１を連結する連結柱１２とを有する。そして、ファスナーエレメントを通すエレメント通路１３が、上翼板１０と下翼板１１の間に形成されている。エレメント通路１３は胴体１の前後方向に延びている。爪孔１４が上翼板１０に形成されている。爪孔１４は、上翼板１０を上下方向に貫通して、エレメント通路１３に連通している。
　胴体１は、ファスナーエレメントに沿って移動できる。胴体１が後方に移動した時、ファスナーエレメントが分離する。胴体１が前方に移動した時、ファスナーエレメントが噛合する。 The fuselage 1 includes an upper wing plate 10 and a lower wing plate 11 that are arranged to face each other in the vertical direction, and a connecting column 12 that connects the upper wing plate 10 and the lower wing plate 11. An element passage 13 through which the fastener element passes is formed between the upper wing plate 10 and the lower wing plate 11. The element passage 13 extends in the front-rear direction of the body 1. A claw hole 14 is formed in the upper blade 10. The claw hole 14 penetrates the upper blade 10 in the vertical direction and communicates with the element passage 13.
The body 1 can move along the fastener element. When the body 1 moves rearward, the fastener element is separated. When the body 1 moves forward, the fastener element meshes.
　支柱１５と係合柱１６が上翼板１０の上面に設けられている。支柱１５と係合柱１６は、上翼板１０の上面から上方に向けて突出している。そして、支柱１５と係合柱１６は、胴体１の前後方向に間隔を空けて配置されている。すなわち、支柱１５は、胴体１の前方寄りに配置されている。また、係合柱１６は、胴体１の後方寄りに配置されている。 A support column 15 and an engagement column 16 are provided on the upper surface of the upper blade 10. The support column 15 and the engagement column 16 protrude upward from the upper surface of the upper blade 10. And the support | pillar 15 and the engagement pillar 16 are arrange | positioned at intervals in the front-back direction of the fuselage | body 1. FIG. That is, the support column 15 is disposed closer to the front of the body 1. Further, the engaging column 16 is disposed near the rear of the body 1.
　溝１７が、上翼板１０の上面に形成されている。溝１７は、スプリング３を収納する。溝１７は、胴体１の左右方向中央に配置されるとともに、胴体１の前後方向に延びている。この溝１７は、係合柱１６を前後方向に貫通している。 A groove 17 is formed on the upper surface of the upper blade 10. The groove 17 accommodates the spring 3. The groove 17 is disposed at the center in the left-right direction of the body 1 and extends in the front-rear direction of the body 1. The groove 17 penetrates the engaging column 16 in the front-rear direction.
　カバー２は、上面板２０と、前面板２１と、後面板２２と、左右の側面板２３とを備え、下面が開口したカバー本体２ａを有する。係止片２４が、後面板２２の下端から突出している。カム面２５が、左右の側面板２３の下面に形成されている。カム面２５は、上方に向けて凹状に湾曲した面である。そして、左右の側面板２３のうち、一方の側面板２３には停止爪２６が設けられている。停止爪２６は、後面板２２寄りに配置され、下方に向けて突出している。 The cover 2 includes an upper surface plate 20, a front surface plate 21, a rear surface plate 22, and left and right side surface plates 23, and has a cover body 2a having an open lower surface. The locking piece 24 protrudes from the lower end of the rear plate 22. A cam surface 25 is formed on the lower surfaces of the left and right side plates 23. The cam surface 25 is a surface curved in a concave shape upward. A stop claw 26 is provided on one of the left and right side plates 23. The stop claw 26 is disposed closer to the rear plate 22 and protrudes downward.
　スプリング３は、長尺な棒状材である。スプリング３は、溝１７に収納された状態で、長さ方向一方側の端部が固定される。そして、スプリング３は、長さ方向他方側の端部３ａが、係合柱１６を越えて、後方に突出する。 Spring 3 is a long rod-shaped material. The spring 3 is housed in the groove 17 and is fixed at one end in the longitudinal direction. Then, the end 3 a on the other side in the length direction of the spring 3 protrudes rearward beyond the engagement column 16.
　引手４は、長さ方向一方側に本体部４ａを有し、長さ方向他方側にリンク部４ｂを有する。本体部４ａは、引手４を操作するときに、指で摘む部分である。リンク部４ｂは、胴体１に連結される部分である。リンク部４ｂは、軸４ｃを有する。軸４ｃは、胴体１の前後方向において、支柱１５と係合柱１６との間に配置される。 The handle 4 has a main body part 4a on one side in the length direction and a link part 4b on the other side in the length direction. The main body portion 4a is a portion that is picked up with a finger when the handle 4 is operated. The link part 4 b is a part connected to the body 1. The link portion 4b has a shaft 4c. The shaft 4 c is disposed between the support column 15 and the engagement column 16 in the front-rear direction of the body 1.
　カバー２は、上翼板１０の上面に配置される。これにより、引手４の軸４ｃは、胴体１の上下方向において、胴体１とカバー２の間に配置される。引手４は、軸４ｃを中心にして回転可能である。この時、カバー２は、支柱１５と係合柱１６を覆うと共に、係止片２４がスプリング３の端部３ａの下面に接するように配置される。そして、カバー２は、左右の側面板２３の前面板２１寄りの部分が、支柱１５に取り付けられる。カバー２は、支柱１５を支点として、上下方向に揺動自在である。　 The cover 2 is disposed on the upper surface of the upper blade 10. As a result, the shaft 4 c of the handle 4 is disposed between the body 1 and the cover 2 in the vertical direction of the body 1. The handle 4 is rotatable about the shaft 4c. At this time, the cover 2 covers the support column 15 and the engagement column 16, and is disposed so that the locking piece 24 contacts the lower surface of the end 3 a of the spring 3. The cover 2 is attached to the support column 15 at portions of the left and right side plates 23 near the front plate 21. The cover 2 is swingable in the vertical direction with the support column 15 as a fulcrum. *
　カバー２は、スプリング３の端部３ａが係止片２４に接することにより、常に下向きに付勢されている。これにより、カバー２は、下方への移動限界である第１位置に保持される。
　引手４は、カバー２が第１位置に保持されている時、図２に示すように、胴体１の前後方向と平行な水平姿勢となる。また、停止爪２６は、カバー２が第１位置に保持されている時、図２に示すように、爪孔１４からエレメント通路１３に入り込む。これにより、停止爪２６は、エレメント通路１３内を通る図示しないファスナーエレメントに係合する。すなわち、胴体１は、ファスナーエレメントに沿って移動できなくなる。 The cover 2 is always urged downward by the end 3 a of the spring 3 contacting the locking piece 24. As a result, the cover 2 is held at the first position, which is the lower limit of movement.
When the cover 2 is held at the first position, the puller 4 takes a horizontal posture parallel to the front-rear direction of the body 1 as shown in FIG. Further, when the cover 2 is held at the first position, the stop claw 26 enters the element passage 13 from the claw hole 14 as shown in FIG. Thereby, the stop pawl 26 engages with a fastener element (not shown) passing through the element passage 13. That is, the body 1 cannot move along the fastener element.
　カバー２は、引手４を指で摘んで引き上げると、図３に示すように、斜め上方に移動する。これにより、カバー２は、上方への移動限界である第２位置に保持される。この時、引手４の軸４ｃは、カバー２のカム面２５に接して、カバー２をスプリング３の付勢力に抗して押し上げる。
　停止爪２６は、カバー２が第２位置に保持されている時、エレメント通路１３から抜け出す。これにより、停止爪２６は、図示しないファスナーエレメントとの係合が解除される。すなわち、胴体１は、ファスナーエレメントに沿って移動できるようになる。
　引手４から指を離し、引手４の引き上げを解除した時、カバー２は、スプリング３の付勢力によって自動的に第１位置に変位する。 When the handle 2 is picked up by a finger and pulled up, the cover 2 moves obliquely upward as shown in FIG. As a result, the cover 2 is held at the second position, which is the upper movement limit. At this time, the shaft 4 c of the handle 4 contacts the cam surface 25 of the cover 2 and pushes up the cover 2 against the urging force of the spring 3.
The stop pawl 26 comes out of the element passage 13 when the cover 2 is held at the second position. Thereby, the stop claw 26 is disengaged from a fastener element (not shown). That is, the body 1 can move along the fastener element.
When the finger is released from the handle 4 and the lifting of the handle 4 is released, the cover 2 is automatically displaced to the first position by the urging force of the spring 3.
　前述した自動停止装置付きスライダーは、スライダー組立機で組み立てられた時、部品の欠落や組み付け誤りなどで、自動停止機能を有さない不良品となることがある。
　そこで、スライダーが良品であるか不良品であるかを検査する検査装置が特許文献２に開示されている。
　この検査装置は、引手を上下に揺動させ、その揺動量を検知レバーと検知ユニットで検知している。そして、揺動量に基づき良品と不良品とを判別するようにしている。 The slider with the automatic stop device described above may become a defective product that does not have an automatic stop function due to missing parts or incorrect assembly when assembled by a slider assembly machine.
Therefore, Patent Document 2 discloses an inspection apparatus that inspects whether a slider is a non-defective product or a defective product.
In this inspection apparatus, the handle is swung up and down, and the swing amount is detected by the detection lever and the detection unit. A good product and a defective product are discriminated based on the swing amount.

　従来の検査装置は、引手の揺動量に基づいて良品と不良品とを判別しているので、引手の形状や重量が異なる場合に、その都度検知バーの位置を調整する必要がある。この調整は、煩雑な作業であり、時間がかかる。 Since the conventional inspection apparatus discriminates between non-defective products and defective products based on the swing amount of the handle, it is necessary to adjust the position of the detection bar each time the shape and weight of the handle are different. This adjustment is a complicated operation and takes time.
　本発明は、前述の課題を解決するためになされたものでる。その目的は、スライダー組立機のスライダー検査装置が、引手の形状や重量が異なるスライダーを、短時間で良品か不良品かを検査できるようにすることである。 The present invention has been made to solve the above-described problems. The purpose is to enable the slider inspection device of the slider assembling machine to inspect the sliders with different shapes and weights of the handle whether they are good or defective in a short time.
　本発明は、エレメント通路１３を有する胴体１と、停止爪２６を有するカバー２を備え、カバー２は、停止爪２６がエレメント通路１３に入り込む第１位置と、停止爪２６がエレメント通路１３から抜け出す第２位置とに変位可能なスライドファスナー用スライダーの検査装置であって、
　前記カバー２を第１位置から第２位置へ向けて変位させる変位手段５０と、
　変位後の前記カバー２を撮影するカメラ５１と、
　前記カメラ５１で撮影した画像と、予め記憶した画像とを比較して、スライダーの良否を判定する良否判定手段８０とを備えることを特徴とするスライドファスナー用スライダーの検査装置である。 The present invention includes a body 1 having an element passage 13 and a cover 2 having a stop claw 26. The cover 2 has a first position where the stop claw 26 enters the element passage 13, and the stop claw 26 comes out of the element passage 13. An inspection device for a slide fastener slider displaceable to a second position,
Displacement means 50 for displacing the cover 2 from the first position toward the second position;
A camera 51 for photographing the cover 2 after displacement;
A slide fastener slider inspecting apparatus comprising: a pass / fail judgment means for judging pass / fail of a slider by comparing an image photographed by the camera 51 with an image stored in advance.
　このようにすれば、カバー２が、変位手段５０によって、第１位置から第２位置へ向けて正常に変位するか否かを判別することができる。また、カバー２が胴体１に対して適正に取り付けられているか否かを判定することができる。 In this way, it is possible to determine whether or not the cover 2 is normally displaced from the first position toward the second position by the displacement means 50. Further, it can be determined whether or not the cover 2 is properly attached to the body 1.
　本発明の検査装置は、前記カバー２は、スプリング３によって第１位置へ移動するように付勢されており、
　前記カメラ５１は、第２位置から第１位置へ変位したカバー２を撮影し、
　前記良否判定手段８０は、前記カメラ５１で撮影した画像と、予め記憶した画像とを比較して、スライダーの良否を判定する。 In the inspection apparatus of the present invention, the cover 2 is urged to move to the first position by the spring 3,
The camera 51 photographs the cover 2 displaced from the second position to the first position,
The pass / fail determination means 80 compares the image captured by the camera 51 with an image stored in advance to determine pass / fail of the slider.
　このようにすれば、カバー２が、スプリング３によって、第２位置から第１位置へ正常に変位するか否かを判定することができる。 In this way, it can be determined whether or not the cover 2 is normally displaced from the second position to the first position by the spring 3.
　本発明の検査装置は、前記胴体１と前記カバー２の間に引手４が配置されており、
前記変位手段５０は、前記引手４の位置を変位させることで前記カバー２を第２位置へ向けて移動させている。
　好ましくは、前記変位手段５０が、移動手段によって上下方向に移動可能であり、
前記移動手段は、前記変位手段５０を、前記引手４と離間する上方位置と、前記引手４を押し下げる下方位置とに移動させている。 In the inspection apparatus of the present invention, a handle 4 is disposed between the body 1 and the cover 2.
The displacing means 50 moves the cover 2 toward the second position by displacing the position of the handle 4.
Preferably, the displacement means 50 is movable in the vertical direction by the moving means,
The moving means moves the displacing means 50 to an upper position that is separated from the handle 4 and a lower position that pushes down the handle 4.
　このようにすれば、変位手段５０がカバー２を第２位置へ向けて容易に移動させることができる。よって、検査装置は、カバー２を変位させるための構造を簡略化することができる。 In this way, the displacement means 50 can easily move the cover 2 toward the second position. Therefore, the inspection apparatus can simplify the structure for displacing the cover 2.
　本発明の検査装置は、前記変位手段５０が、前記移動手段によって上方位置と下方位置の間の中間位置に停止可能であり、
前記カバー２は、前記変位手段５０が中間位置に停止した時、第１位置に移動している。 In the inspection apparatus of the present invention, the displacement means 50 can be stopped at an intermediate position between the upper position and the lower position by the moving means,
The cover 2 moves to the first position when the displacement means 50 stops at the intermediate position.
　このようにすれば、変位手段５０は、第１位置のカバー２を撮影する時、引手が上下に振れ動くことを抑制することができる。よって、検査装置は、スライダーを正確に良否判定することができる。 In this way, the displacement means 50 can suppress the swinging movement of the handle up and down when photographing the cover 2 at the first position. Therefore, the inspection apparatus can determine the quality of the slider accurately.
　本発明の検査装置は、前記移動機構が、回転する第１カム６６と、当該第１カム６６の回転によって上下方向に移動する第１昇降体６０とを有し、
　前記変位手段５０は、前記第１昇降体６０に取り付けられている。
　好ましくは、前記移動機構は、回転する第２カム６７と、当該第２カム６７の回転によって上下方向に移動する第２昇降体６１とを有し、
　前記カメラ５１は、前記第２昇降体６１に取り付けられている。 In the inspection apparatus of the present invention, the moving mechanism includes a first cam 66 that rotates, and a first lifting body 60 that moves in the vertical direction by the rotation of the first cam 66.
The displacement means 50 is attached to the first elevating body 60.
Preferably, the moving mechanism includes a second cam 67 that rotates, and a second elevating body 61 that moves up and down by the rotation of the second cam 67.
The camera 51 is attached to the second lifting body 61.
　このようにすれば、移動機構は、変位手段５０やカメラ５１を高速度で安定して動作させることができる。よって、検査装置は、スライダーを短時間で正確に良否判定することができる。 In this way, the moving mechanism can stably operate the displacement means 50 and the camera 51 at a high speed. Therefore, the inspection apparatus can accurately determine the quality of the slider in a short time.
　本発明の検査装置は、前記第１カム６６及び前記第２カム６７がサーボモータ６４で回転し、
　前記サーボモータ６４の回転により前記変位手段５０の位置を検知し、その検知に基づき前記カメラ５１による撮影を開始するようにしている。 In the inspection apparatus of the present invention, the first cam 66 and the second cam 67 are rotated by a servo motor 64,
The position of the displacement means 50 is detected by the rotation of the servo motor 64, and based on the detection, the photographing by the camera 51 is started.
　このようにすれば、検査装置は、変位手段５０の位置に基づいて、第１位置のカバーと、第２位置のカバーを撮影するので、カバーの位置を検出する検出手段を別途設ける必要が無く、構造を簡略化することができる。 According to this configuration, the inspection apparatus photographs the cover at the first position and the cover at the second position based on the position of the displacement means 50, so there is no need to separately provide detection means for detecting the position of the cover. The structure can be simplified.
　本発明によれば、変位手段５０がカバー２を第１位置と第２位置とに変位させ、カメラ５１が各位置のカバー２を撮影し、撮影した画像を予め記憶した画像と比較して良否判定するので、引手の形状や重量が異なるスライダーを短時間で正確に良否判定することができる。 According to the present invention, the displacement means 50 displaces the cover 2 between the first position and the second position, the camera 51 photographs the cover 2 at each position, and compares the photographed image with a prestored image. Since the determination is made, it is possible to accurately determine whether or not the sliders having different shapes and weights of the handle are accurate in a short time.

　本発明のスライダー組立機は、図１、図２、図３に示すスライドファスナー用スライダーを組み立てる。スライダーは、上述したごとく、胴体１と、カバー２と、スプリング３と、引手４を有する。胴体１は、内部にエレメント通路１３を有する。カバー２は、停止爪２６を有する。このスライダー組立機は、図４に概略的に示すように、機械フレーム４０と、機械フレーム４０に対して回転可能に支持されたターンテーブル４１を備えている。機械フレーム４０は、基台４０ａと、この基台４０ａの上面から起立する柱４０ｂを備えている。
　ターンテーブル４１は、柱４０ｂを中心にして、所定角度ごとに矢印方向へ間欠的に回転する。ターンテーブル４１の周囲には、胴体供給装置４２、スプリング供給装置４３、引手供給装置４４、カバー供給装置４５、カバー取付装置４６、本発明に係る検査装置４７、排出装置４８が、ターンテーブル４１の回転方向に間隔を空けて配置されている。
　ターンテーブル４１は円盤状である。ターンテーブル４１の周縁部には、スライダーの胴体１を収納する収納凹部４１ａが形成されている。収納凹部４１ａは、ターンテーブル４１の回転方向に間隔を空けて複数配置されている。 The slider assembling machine of the present invention assembles the slide fastener slider shown in FIGS. As described above, the slider includes the body 1, the cover 2, the spring 3, and the handle 4. The body 1 has an element passage 13 therein. The cover 2 has a stop claw 26. As schematically shown in FIG. 4, the slider assembling machine includes a machine frame 40 and a turntable 41 supported to be rotatable with respect to the machine frame 40. The machine frame 40 includes a base 40a and a column 40b that stands from the upper surface of the base 40a.
The turntable 41 rotates intermittently in the direction of the arrow every predetermined angle around the column 40b. Around the turntable 41, there are a body supply device 42, a spring supply device 43, a handle supply device 44, a cover supply device 45, a cover mounting device 46, an inspection device 47 according to the present invention, and a discharge device 48. Arranged at intervals in the direction of rotation.
The turntable 41 has a disk shape. A storage recess 41 a for storing the slider body 1 is formed in the peripheral portion of the turntable 41. A plurality of storage recesses 41 a are arranged at intervals in the rotation direction of the turntable 41.
　前述のスライダー組立機はスライダーを次のようにして組み立てる。
　スライダー組立機は、ターンテーブル４１を所定角度だけ回転させて、１つの収納凹部４１ａを胴体供給装置４２に対向させる。胴体供給装置４２は、胴体１を収納凹部４１ａに供給する。
　この後、胴体１が収納された収納凹部４１ａは、ターンテーブル４１が所定角度だけ回転することにより、スプリング供給装置４３と対向する。スプリング供給装置４３は、胴体１にスプリング３を供給する。
　以下、同様にして、引手供給装置４４が、胴体１に引手４を供給する。次いで、カバー供給装置４５が、カバー２を胴体１に供給する。次いで、カバー取付装置４６が、カバー２を胴体１に取り付ける。このとき、カバー２は、胴体１に対して、停止爪２６がエレメント通路１３に入り込む第１位置と、停止爪２６がエレメント通路１３から抜け出す第２位置とに変位可能に取り付けられる。これにより、スライダーの組み立てが完了する。
　組立後のスライダーは、検査装置４７で検出される。次いで、排出装置４８は、ターンテーブル４１の収納凹部４１ａからスライダーを排出する。この時、排出装置４８は、検査装置４７の検出結果に基づき、スライダーを良品と不良品とに分けて排出する。 The above slider assembly machine assembles the slider as follows.
The slider assembling machine rotates the turntable 41 by a predetermined angle so that one storage recess 41 a faces the body supply device 42. The body supply device 42 supplies the body 1 to the storage recess 41a.
Thereafter, the housing recess 41a in which the body 1 is housed faces the spring supply device 43 as the turntable 41 rotates by a predetermined angle. The spring supply device 43 supplies the spring 3 to the body 1.
Hereinafter, similarly, the handle supply device 44 supplies the handle 4 to the body 1. Next, the cover supply device 45 supplies the cover 2 to the body 1. Next, the cover attaching device 46 attaches the cover 2 to the body 1. At this time, the cover 2 is attached to the body 1 so as to be displaceable at a first position where the stop pawl 26 enters the element passage 13 and a second position where the stop pawl 26 exits from the element passage 13. Thereby, the assembly of the slider is completed.
The assembled slider is detected by the inspection device 47. Next, the discharge device 48 discharges the slider from the storage recess 41 a of the turntable 41. At this time, the discharge device 48 discharges the slider into a non-defective product and a defective product based on the detection result of the inspection device 47.
　本発明の検査装置４７を説明する。
　図５及び図６に示すように、スライダーは、その胴体１がターンテーブル４１の収納凹部４１ａに収納される。この時、胴体１の連結柱１２は、ターンテーブル４１の周縁４１ｂ側に配置される。また、カバー２の停止爪２６は、ターンテーブル４１の回転中心側に配置される。この停止爪２６は、胴体１のエレメント通路１３に突出している。また、引手４は、軸４ｃが胴体１とカバー２の間に配置されている。そして、引手４は、胴体１の上面において、連結柱１２側に向けて倒れた水平姿勢で配置されている。この引手４は、本体部４ａがターンテーブル４１の周縁４１ｂよりも外側に突出している。 The inspection apparatus 47 of the present invention will be described.
As shown in FIGS. 5 and 6, the body 1 of the slider is housed in the housing recess 41 a of the turntable 41. At this time, the connecting column 12 of the body 1 is disposed on the peripheral edge 41 b side of the turntable 41. Further, the stop claw 26 of the cover 2 is arranged on the rotation center side of the turntable 41. The stop pawl 26 protrudes into the element passage 13 of the body 1. The handle 4 has a shaft 4 c disposed between the body 1 and the cover 2. And the handle 4 is arrange | positioned on the upper surface of the trunk | drum 1 with the horizontal attitude | position which fell down toward the connection pillar 12 side. As for this handle 4, the main-body part 4a protrudes outside the peripheral edge 41b of the turntable 41. As shown in FIG.
　検査装置４７は、カバー２が適正な位置に変位するか否かを検査する。検査前のカバー２は、スプリング３の付勢力によって下方へ押し下げられている。すなわち、カバー２は、下方への移動限界である第１位置に位置している。停止爪２６は、カバー２が第１位置に位置している時、胴体１のエレメント通路１３に入り込んだ状態となる。そして、検査装置４７は、矢印ａで示すように、引手４の本体部４ａに下向きの力を負荷する。これにより、引手４は、押し下げられるとともに、引手４の軸４ｃでカバー２を押し上げる。すなわち、カバー２は、第１位置よりも上方に位置する第２位置に変位する。停止爪２６は、カバー２が第２位置に保持されている時、胴体１のエレメント通路１３から抜け出した状態となる。 The inspection device 47 inspects whether or not the cover 2 is displaced to an appropriate position. The cover 2 before the inspection is pushed downward by the urging force of the spring 3. That is, the cover 2 is located at the first position that is the lower limit of movement. The stop pawl 26 enters the element passage 13 of the body 1 when the cover 2 is in the first position. The inspection device 47 applies a downward force to the main body 4a of the handle 4 as indicated by an arrow a. Thereby, the handle 4 is pushed down and the cover 2 is pushed up by the shaft 4 c of the handle 4. That is, the cover 2 is displaced to the second position located above the first position. When the cover 2 is held at the second position, the stop pawl 26 comes out of the element passage 13 of the body 1.
　検査装置４７は、図５及び図６に示すように、ターンテーブル４１の上方に配置された装置本体４７ａを有する。装置本体４７ａは、柱４０ｂに取り付けられている。そして、検査装置４７は、引手４と上下方向に対向するように配置されたプッシャ５０を備えている。プッシャ５０は、カバー２の位置を変位させる変位手段である。プッシャ５０は、引手４の本体部４ａに下向きの力を負荷したり、負荷しないようにする。 The inspection apparatus 47 has an apparatus main body 47a disposed above the turntable 41 as shown in FIGS. The apparatus main body 47a is attached to the column 40b. The inspection device 47 includes a pusher 50 disposed so as to face the handle 4 in the vertical direction. The pusher 50 is a displacement means for displacing the position of the cover 2. The pusher 50 loads a downward force on the main body portion 4a of the handle 4 or prevents it from being loaded.
　プッシャ５０は、装置本体４７ａに対して上下方向に移動可能である。即ち、プッシャ５０は、引手４に下向きの力を負荷する下方位置と、引手４に下向きの力を負荷しない上方位置とに渡って移動する。プッシャ５０は、スライダーが、ターンテーブル４１の回転によって、検査位置に移動してきた時、スライダーの引手４における前述の突出している部分の真上に位置する。また、プッシャ５０は、ターンテーブル４１の回転時に、上方位置に配置する。これにより、プッシャ５０は、ターンテーブル４１の回転時に、引手４と接触することを回避できる。 The pusher 50 is movable in the vertical direction with respect to the apparatus main body 47a. That is, the pusher 50 moves over a lower position where a downward force is applied to the puller 4 and an upper position where a downward force is not applied to the puller 4. The pusher 50 is located immediately above the protruding portion of the slider puller 4 when the slider has moved to the inspection position by the rotation of the turntable 41. Further, the pusher 50 is disposed at an upper position when the turntable 41 is rotated. Thereby, the pusher 50 can avoid contacting with the handle 4 when the turntable 41 rotates.
　また、検査装置４７は、カバー２を撮影するカメラ５１と、カバー２を照明する照明具５２を備えている。
　カメラ５１及び照明具５２は、前述の装置本体４７ａに対して上下方向に移動可能である。即ち、カメラ５１及び照明具５２は、カバー２よりも上方の待機位置と、カバー２とほぼ同一高さの下方の撮影位置とに渡って移動する。カメラ５１及び照明具５２は、ターンテーブル４１の回転時に、上方の待機位置に配置する。これにより、カメラ５１及び照明具５２は、ターンテーブル４１の回転時に、カバー２と接触することを回避できる。 Further, the inspection device 47 includes a camera 51 that captures an image of the cover 2 and an illumination tool 52 that illuminates the cover 2.
The camera 51 and the illuminating tool 52 are movable in the vertical direction with respect to the aforementioned apparatus main body 47a. That is, the camera 51 and the illumination tool 52 move over a standby position above the cover 2 and a photographing position below the cover 2 at substantially the same height. The camera 51 and the illumination tool 52 are arranged at an upper standby position when the turntable 41 is rotated. Thereby, the camera 51 and the illumination tool 52 can avoid contacting the cover 2 when the turntable 41 rotates.
　カメラ５１と照明具５２は、プッシャ５０の左右両側、つまりスライダーの左右両側に対向して配置されている。
　例えば、カメラ５１はターンテーブル４１の回転方向下流側に配置している。そして、照明具５２はターンテーブル４１の回転方向上流側に配置している。 The camera 51 and the illumination tool 52 are disposed so as to face both the left and right sides of the pusher 50, that is, the left and right sides of the slider.
For example, the camera 51 is arranged on the downstream side in the rotation direction of the turntable 41. The illuminator 52 is arranged on the upstream side of the turntable 41 in the rotation direction.
　次に、検査装置４７の検査動作を説明する。
　検査装置４７は、図５及び図６に示すように、プッシャ５０を上方位置に配置すると共に、カメラ５１及び照明具５２を上方の待機位置に配置する。
　プッシャ５０、カメラ５１、及び照明具５２は、スライダーがスライダー検査位置に配置された時、下方へ移動する。この時、カバー２は第１位置に保持されている。プッシャ５０は、下方位置へ移動することで、引手４の本体部４ａを押し下げる。これにより、引手４の軸４ｃは、図７に示すように、スプリング３の付勢力に抗してカバー２を押し上げる。すなわち、カバー２は第１位置から第２位置へと変位する。この時、停止爪２６が胴体１のエレメント通路１３から抜け出す。
　これと同時に、カメラ５１及び照明具５２が下方の撮影位置に移動する。カメラ５１は、第２位置へ変位後のカバー２を撮影する。
　このときのカメラ５１の画像５１Ａは図８に示すようである。 Next, the inspection operation of the inspection apparatus 47 will be described.
As shown in FIGS. 5 and 6, the inspection device 47 arranges the pusher 50 at the upper position, and arranges the camera 51 and the illumination tool 52 at the upper standby position.
The pusher 50, the camera 51, and the lighting tool 52 move downward when the slider is disposed at the slider inspection position. At this time, the cover 2 is held in the first position. The pusher 50 moves down to push down the main body 4a of the handle 4. As a result, the shaft 4c of the handle 4 pushes up the cover 2 against the biasing force of the spring 3, as shown in FIG. That is, the cover 2 is displaced from the first position to the second position. At this time, the stop pawl 26 comes out of the element passage 13 of the body 1.
At the same time, the camera 51 and the illumination tool 52 move to the lower photographing position. The camera 51 photographs the cover 2 after being displaced to the second position.
An image 51A of the camera 51 at this time is as shown in FIG.
　検査装置４７は、カバー２の撮影を完了した時、カメラ５１及び照明具５２を撮影位置に配置したままで、プッシャ５０を上方へ移動させる。この時、プッシャ５０は、上下方向の中間位置に停止する。つまり、プッシャ５０は、引手４と若干の隙間を空けて離間する位置、もしくは、引手４に接しているが、引手４に下向きの力を負荷しない位置に停止する。この時、引手４は、プッシャ５０による下向きの負荷から解放される。これにより、カバー２は、スプリング３の付勢力によって、下方へ移動する。すなわち、カバー２は第１位置に変位する。また、引手４は、押し下げ前の水平姿勢に戻る（図９参照）。
　これと同時にカメラ５１は、第１位置のカバー２を撮影する。
　このときのカメラ５１の画像５１Ｂは図１０に示すようである。 The inspection device 47 moves the pusher 50 upward while keeping the camera 51 and the illumination tool 52 in the photographing position when the photographing of the cover 2 is completed. At this time, the pusher 50 stops at an intermediate position in the vertical direction. That is, the pusher 50 stops at a position where the pusher 50 is spaced apart from the handle 4 or a position where the pusher 50 is in contact with the handle 4 but does not apply a downward force to the handle 4. At this time, the handle 4 is released from the downward load by the pusher 50. As a result, the cover 2 moves downward by the urging force of the spring 3. That is, the cover 2 is displaced to the first position. Further, the puller 4 returns to the horizontal posture before being pushed down (see FIG. 9).
At the same time, the camera 51 photographs the cover 2 at the first position.
An image 51B of the camera 51 at this time is as shown in FIG.
　検査装置４７は、カバー２の撮影が完了した時、プッシャ５０をさらに上昇させる。これにより、プッシャ５０は、引手４と離れた上方位置まで移動する。これと同時に、カメラ５１及び照明具５２が上方の待機位置まで移動する。 The inspection device 47 further raises the pusher 50 when the photographing of the cover 2 is completed. As a result, the pusher 50 moves to an upper position away from the handle 4. At the same time, the camera 51 and the illumination tool 52 move to the upper standby position.
　検査装置４７は、図６に示すように、カメラ５１に接続された良否判定手段８０を有する。良否判定手段８０は、図８及び図１０に示すカメラ５１の画像５１Ａ，５１Ｂと、予め記憶してある良品の画像を比較して、スライダーの良否を判定する。良否判定手段８０は、画像５１Ａ，５１Ｂが、良品の画像と一致すれば、スライダーが良品であると判断する。一方、良否判定手段８０は、画像５１Ａ，５１Ｂが、良品の画像と一致しなければ、スライダーが不良品であると判断する。 As shown in FIG. 6, the inspection apparatus 47 includes a quality determination unit 80 connected to the camera 51. The pass / fail determination means 80 compares the images 51A and 51B of the camera 51 shown in FIGS. 8 and 10 with the stored non-defective images to determine pass / fail of the slider. The pass / fail determination means 80 determines that the slider is a non-defective product if the images 51A and 51B match the non-defective image. On the other hand, the pass / fail determination means 80 determines that the slider is defective if the images 51A and 51B do not match the non-defective image.
　このように、良否判定手段８０は、カバー２を撮影した画像を良品の画像と比較するので、良品と不良品とを短時間で判別することができる。 As described above, the quality determination means 80 compares the image obtained by photographing the cover 2 with the quality image, so that the quality product and the defective product can be distinguished in a short time.
　また、プッシャ５０は、上方位置と下方位置の間の中間位置で停止可能である。プッシャ５０は、第１位置のカバー２をカメラ５１で撮影するときに、中間位置で停止する。この時、プッシャ５０は、引手４が上下方向に変位することを抑制している。なぜなら、引手４は、プッシャ５０が下方位置から急激に中間位置を経て上方位置に向けて移動すると、上下に振れ動き、検査のたびに位置が異なるからである。
これにより、カメラ５１は、カバー２を正確に撮影できる。よって、検査装置４７は、スライダーの検査精度にバラつきが生じることがなく、高精度に検査できる。 The pusher 50 can be stopped at an intermediate position between the upper position and the lower position. The pusher 50 stops at an intermediate position when the camera 51 photographs the cover 2 at the first position. At this time, the pusher 50 suppresses displacement of the handle 4 in the vertical direction. This is because, when the pusher 50 suddenly moves from the lower position to the upper position via the intermediate position, the puller 4 swings up and down, and the position of the puller 4 changes every time the inspection is performed.
Thereby, the camera 51 can photograph the cover 2 accurately. Therefore, the inspection apparatus 47 can inspect with high accuracy without variation in the inspection accuracy of the slider.
　なお、プッシャ５０は、中間位置で所定の時間だけ停止する。カメラ５１は、所定の時間内に撮影を完了する。プッシャ５０は、所定の時間経過後、上方へ移動して、引手４と離隔する。 The pusher 50 stops at a middle position for a predetermined time. The camera 51 completes shooting within a predetermined time. The pusher 50 moves upward after a predetermined time elapses and is separated from the puller 4.
　さらに、良否判定手段８０は、カメラ５１で撮影した画像を予め記憶した良品の画像と比較するので、カバー２の位置ずれを検査することが可能である。
　良否判定手段８０は、図８に示す画像５１Ａに基づき、カバー２の上下方向の位置（Ｙ軸方向の位置）、カバー２の前後方向の位置（Ｘ軸方向の位置）、水平に対する角度等を検査できる。
　また、良否判定手段８０は、図１０に示す画像５１Ｂに基づき、カバー２の上下方向の位置、カバー２の前後方向の位置、水平に対する角度等を検査できる。
　なお、カバー２の上下方向の位置は、例えば、カバー２の上面板２０の位置に基づき、カバー２の位置ずれを検査することができる。 Furthermore, since the quality determination means 80 compares the image photographed by the camera 51 with a quality image stored in advance, it is possible to inspect the positional deviation of the cover 2.
Based on the image 51A shown in FIG. 8, the pass / fail judgment means 80 determines the vertical position of the cover 2 (position in the Y-axis direction), the longitudinal position of the cover 2 (position in the X-axis direction), the angle with respect to the horizontal, and the like. Can be inspected.
Further, the quality determination unit 80 can inspect the position of the cover 2 in the vertical direction, the position of the cover 2 in the front-rear direction, the angle with respect to the horizontal, and the like based on the image 51B shown in FIG.
The position of the cover 2 in the vertical direction can be inspected for positional deviation of the cover 2 based on the position of the upper surface plate 20 of the cover 2, for example.
　検査装置４７は、プッシャ５０、カメラ５１及び照明具５２を上下方向に移動させる移動手段を有する。
　移動手段は、カムまたはシリンダを採用することができる。移動手段は、検査に要する時間を短縮するために、カムを採用することが好ましい。
　移動手段は、カムと、カムの回転によって上下方向に移動可能な昇降体を有する。プッシャ５０、カメラ５１及び照明具５２は、昇降体に取り付けられ、昇降体とともに上下方向に移動する。 The inspection apparatus 47 includes a moving unit that moves the pusher 50, the camera 51, and the illumination tool 52 in the vertical direction.
A cam or a cylinder can be adopted as the moving means. The moving means preferably employs a cam in order to shorten the time required for the inspection.
The moving means has a cam and a lifting body that can move in the vertical direction by the rotation of the cam. The pusher 50, the camera 51, and the lighting fixture 52 are attached to the lifting body and move in the vertical direction together with the lifting body.
　また、プッシャ５０の上下方向位置は、カムの回転角度で決定される。カムの回転角度は、サーボモータまたはロータリーエンコーダで計測することができる。これにより、プッシャ５０の上下方向位置は、カムの回転角度を基準として検出することができる。すなわち、カバー２が第２位置になった時と、カバー２が第１位置になった時を、カムの回転角度を基準にして検出することができる。そして、その検出信号は、カメラ５１による撮影動作を開始するための信号とすることができる。 Also, the vertical position of the pusher 50 is determined by the cam rotation angle. The rotation angle of the cam can be measured with a servo motor or a rotary encoder. Thereby, the vertical position of the pusher 50 can be detected with reference to the rotation angle of the cam. That is, it is possible to detect when the cover 2 is in the second position and when the cover 2 is in the first position on the basis of the cam rotation angle. The detection signal can be a signal for starting the photographing operation by the camera 51.
　前述の移動手段の一例を図１１、図１２、図１３を参照して説明する。
　移動手段は、第１昇降体６０と、第２昇降体６１と、第３昇降体６２とを有する。各昇降体６０、６１、６２は、装置本体４７ａに取り付けられ、上下方向に移動可能である。

The first arm 68 can swing around a first fulcrum 68a located in the middle in the length direction.
　第２伝達部材８２は、第２アーム７１と、第２アーム７１の長さ方向一方側端部に取り付けられた第２カムフォロア７３と、第２アーム７１の長さ方向他方側端部に取り付けられた第２ローラ７６と、第２アーム７１を一方向に付勢する第２スプリング７２を有する。第２カムフォロア７３は第２カム６７に接している。第２ローラ７６は第２昇降体６１に接している。第２スプリング７２は、第２カムフォロア７３が第２カム６７に常に接するように、第２アーム７１を第２カム６７に向けて付勢している。第２アーム７１は、長さ方向中間部に位置する第２支点７１ａを中心にして揺動可能である。 The second transmission member 82 is attached to the second arm 71, the second cam follower 73 attached to one end portion in the length direction of the second arm 71, and the other end portion in the length direction of the second arm 71.

The second arm 71 can swing around a second fulcrum 71a located in the middle in the length direction.
　第１昇降体６０は、その上部に、上下方向と直交する方向に延びる第１溝７５を有する。第１ローラ７４は第１溝７５内を移動可能に配置されている。第１昇降体６０は、第１アーム６８が第１支点６８ａを中心として上下に揺動した時、上下方向に移動する。
　第２昇降体６１は、その上部に、上下方向と直交する方向に延びる第２溝７７を有する。第２ローラ７６は第２溝７７内を移動可能に配置されている。第２昇降体６１は、第２アーム７１が第２支点７１ａを中心として上下に揺動した時、上下方向に移動する。 The 1st raising / lowering body 60 has the 1st groove | channel 75 extended in the direction orthogonal to an up-down direction in the upper part.

　このようにすることで、第１昇降体６０は、第１カム６６が回転することで、第１伝達部材８１を介して、上下方向に移動する。プッシャ５０は、第１昇降体６０と共に上下方向へ移動する。また、第２昇降体６１及び第３昇降体６２は、第２カム６７が回転することで、第２伝達部材８２を介して、上下方向に移動する。カメラ５１及び照明具５２は、第２昇降体６１及び第３昇降体６２と共に上下方向へ移動する。なお、プッシャ５０とカメラ５１及び照明具５２は、第１カム６６と第２カム６７の形状を適宜設定することで、前述した検査動作で移動することができる。 By doing in this way, the 1st raising / lowering body 60 moves to the up-down direction via the 1st transmission member 81, when the 1st cam 66 rotates. The pusher 50 moves in the vertical direction together with the first lifting body 60. Further, the second elevating body 61 and the third elevating body 62 move in the vertical direction via the second transmission member 82 as the second cam 67 rotates. The camera 51 and the lighting tool 52 move in the vertical direction together with the second elevating body 61 and the third elevating body 62. Note that the pusher 50, the camera 51, and the illumination tool 52 can be moved by the above-described inspection operation by appropriately setting the shapes of the first cam 66 and the second cam 67.
　例えば、プッシャ５０は、図１４に示すように、第１カム６６が１回転した時、第１カム６６の回転角度（回転開始からの経過時間）に応じて、上方位置と、下方位置と、上方位置と下方位置の間の中間位置へと随時移動する。具体的には、プッシャ５０が、第１カム６６の回転によって以下のごとく移動する。まず、プッシャ５０は、上方位置から下方位置まで下降する。次いで、プッシャ５０は、中間位置まで上昇する。プッシャ５０は、第１カム６６が所定の角度を回転するまで中間位置で停止する。次いで、プッシャ５０は、上方位置まで上昇する。 For example, as shown in FIG. 14, when the first cam 66 makes one rotation, the pusher 50 has an upper position, a lower position, and a position corresponding to the rotation angle (elapsed time from the start of rotation) of the first cam 66. It moves from time to time to an intermediate position between the upper and lower positions. Specifically, the pusher 50 moves as follows by the rotation of the first cam 66. First, the pusher 50 is lowered from the upper position to the lower position. Next, the pusher 50 is raised to the intermediate position. The pusher 50 stops at an intermediate position until the first cam 66 rotates a predetermined angle. Next, the pusher 50 is raised to the upper position.
　また、カメラ５１は、図１４に示すように、第２カム６７が１回転した時、第２カム６７の回転角度（回転開始からの経過時間）に応じて、待機位置と撮影位置との間を移動する。具体的には、カメラ５１が、第２カム６７の回転によって以下のごとく移動する。まず、カメラ５１は、待機位置から撮影位置まで下降する。次いで、カメラ５１は、第２カム６７が所定の角度を回転するまで撮影位置で停止する。次いで、カメラ５１は、待機位置まで上昇する。 Further, as shown in FIG. 14, when the second cam 67 makes one rotation, the camera 51 has a distance between the standby position and the photographing position according to the rotation angle of the second cam 67 (elapsed time from the start of rotation). To move. Specifically, the camera 51 moves as follows by the rotation of the second cam 67. First, the camera 51 is lowered from the standby position to the shooting position. Next, the camera 51 stops at the photographing position until the second cam 67 rotates a predetermined angle. Next, the camera 51 rises to the standby position.
　そして、検査装置４７は、第１カム６６の回転角度に基づいて、プッシャ５０の上下方向の位置を検知し、カメラ５１による撮影動作を開始する。 Then, the inspection device 47 detects the vertical position of the pusher 50 based on the rotation angle of the first cam 66, and starts the photographing operation by the camera 51.
　このように、検査装置４７は、プッシャ５０の上下方向の位置に基づいてカメラ５１による撮影動作を開始するので、スライダーを正確に撮影し、検査することができる。 Thus, since the inspection device 47 starts the photographing operation by the camera 51 based on the vertical position of the pusher 50, it is possible to accurately photograph and inspect the slider.
　検査装置４７は、前述の形態に限定されない。例えば、変位手段は、引手４を摘んで引き上げるグリッパであってもよい。この場合、グリッパは、引手４を引き上げることでカバーを第１位置から第２位置へ変位させる。また、サーボモータ６４は、プーリとベルトを介して、回転軸６５に回転力を伝動しても良い。また、カメラ５１と照明具５２は、個別に移動してもよい。更に、カメラ５１は、常に撮影位置に配置されていてもよい。 The inspection device 47 is not limited to the above-described form. For example, the displacement means may be a gripper that picks up and pulls the handle 4. In this case, the gripper moves the cover from the first position to the second position by pulling up the handle 4. The servo motor 64 may transmit a rotational force to the rotary shaft 65 via a pulley and a belt. Further, the camera 51 and the lighting device 52 may be moved individually. Furthermore, the camera 51 may always be disposed at the shooting position.
