Description

本発明は、例えばベルトコンベア上を搬送されてくる物品が良品である場合は後段の装置に送り、不良品の場合はその途中で取り除く振り分け装置に関する。 The present invention relates to a sorting apparatus that, for example, sends an article conveyed on a belt conveyor to a subsequent apparatus when the article is a non-defective product and removes it in the middle when the article is defective.

ベルトコンベア等で次々と搬送されてくる物品を、例えば重量計測することにより、目標とする範囲に入っているか否かを判別したり、またＸ線で異物が混入していないかどうかを判別して良品または不良品を選り分ける選別機が知られている。例えば重量選別機では、計量コンベアの前段に物品を計量コンベアにスムーズに搬入するための送り込みコンベアが設けられ、計量コンベアの後段には、計量結果に基づいて物品を選別する振り分け装置が設けられている。 For example, by measuring the weight of articles conveyed one after another on a belt conveyor, etc., it is determined whether they are within the target range, or whether X-rays are not contaminated with foreign matter. A sorter that sorts non-defective or defective products is known. For example, in a weight sorter, an infeed conveyor for smoothly carrying articles to the weighing conveyor is provided at the front stage of the weighing conveyor, and a sorting apparatus for sorting the articles based on the weighing results is provided at the latter stage of the weighing conveyor. Yes.

従来の技術として例えば非特許文献１に示す装置がある。ここに紹介されている技術はフリッパ形式の振り分け装置であるが、その中でも第１図においては、不良品であっても振り分けフリッパを飛び越えて良品の方に搬送され誤った振り分けをすることが記載されている。 As a conventional technique, for example, there is a device shown in Non-Patent Document 1. The technology introduced here is a flipper type sorting device. Among them, FIG. 1 describes that even a defective product jumps over the sorting flipper and is transported to a non-defective product. Has been.

また、このような飛び越えを防止する方法が第２図及び第３図で紹介されている。この方法は計量済みの物品が不良品であった場合コンベアラインの下方に排出するものであって、計量コンベアより送り出された物品が振り分け装置を飛び越えないように工夫されたものである。この文献によれば、振り分け搬送路を形成するベルトコンベアが直列２台設けられ、計量コンベアから最初に乗り移るコンベアを第１のコンベアとしその終端側を下方に傾斜させ、その次に連なるコンベアを第２のコンベアとしてその始端側を上方へ傾斜させる構造としたもので、計量コンベアから搬送されてきた不良品はこれら第１及び第２のコンベアを飛び越えることなく強制的にコンベアラインの下方に放出するものである。 A method of preventing such jumping is introduced in FIGS. 2 and 3. In this method, when a measured article is defective, it is discharged below the conveyor line, and the article sent out from the weighing conveyor is devised so as not to jump over the sorting device. According to this document, two belt conveyors that form a sorting and conveying path are provided in series, the conveyor that first transfers from the weighing conveyor is the first conveyor, its end side is inclined downward, and the next consecutive conveyor is the first conveyor. As the second conveyor, the starting end side is inclined upward, and defective products conveyed from the weighing conveyor are forcibly discharged below the conveyor line without jumping over the first and second conveyors. Is.

ところが、最近では高い処理能力の選別機が要求されるようになり、それに追従する計測技術は進歩したものの速い物品の流れを処理する機構に限界があった。近時要求されている能力は、例えば包装された物品で１分間に６００袋である。このような高い処理量になると前述したような高速ゲート式振り分け装置であっても物品の流れに勢いがあるため振り分け装置を飛び越えたり衝突したりして振り分け確度が著しく低下する。従来の方法ではどうしても物品に傷を付けたり物品を変形させたり更には物品を破袋させてしまう事態になる。このような場合即座にラインの停止をかけるが、それでも一瞬にして不良品の山ができる。このようなことから従来の技術のみでは、高速度で処理することはできず新たな振り分け装置が望まれていた。 However, in recent years, a sorter with a high processing capacity has been required, and although the measurement technology to follow it has advanced, there is a limit to the mechanism for processing a fast flow of articles. A recently required capacity is, for example, 600 bags per minute for a packaged article. At such a high throughput, even the high-speed gate type sorting apparatus as described above has a momentum in the flow of articles, so that the sorting accuracy is significantly lowered by jumping over or colliding with the sorting apparatus. In the conventional method, the article is inevitably damaged, the article is deformed, and the article is broken. In such a case, the line is stopped immediately, but still there is a pile of defective products in an instant. For this reason, the conventional technique alone cannot process at a high speed, and a new distribution device has been desired.

本発明は、このような従来技術の問題点に鑑みなされたもので、高速度で処理する選別機の振り分け装置において、物品に傷を付けることなく、また変形や破袋を生じさせることなく振り分け確度の高い振り分け装置を提供するものである。 The present invention has been made in view of such problems of the prior art, and in a sorter sorting apparatus that processes at a high speed, sorting without damaging articles or causing deformation or bag breakage. A sorting apparatus with high accuracy is provided.

請求項１における発明は、前段に良品または不良品を判定する物品判定装置を備えた複数の搬送コンベアから成る物品振り分け装置であって、上記搬送コンベアの途中に搬送通路を設けてこの搬送通路を振り分け装置としたものである。搬送コンベア上の前段に設けられている物品判定装置は、例えば金属異物検出装置やＸ線異物検出装置等であり、これらからの情報により振り分けるものである。そしてこの搬送通路の前段には、到来する物品を搬送通路の手前で検出する物品検出装置が設けられると共に、振り分け装置制御手段が設けられている。上記の搬送通路には片方がヒンジの開閉フリッパを設けると共に、その開閉フリッパの上部には圧縮エヤーを下方に向けて吹き付けるエヤーノズルが設けられている。上記の振り分け装置制御手段は、搬送されてくる物品が良品であると判定された信号を受信したとき上記フリッパが「閉」の状態となるよう制御し、上記物品が搬送通路上を通過して後段の搬送コンベアに向かうように上記搬送通路を平坦となるよう制御する。また上記の振り分け装置制御手段は、搬送されてくる物品が不良品であると判定された信号を受信したとき上記開閉フリッパが「開」の状態となるよう制御し、所定のタイミングで上記エヤーノズルより圧縮エヤーを吹き付けその不良品を搬送通路の下方に振り分けるよう制御することを特徴としている。 The invention according to claim 1 is an article sorting apparatus comprising a plurality of transfer conveyors provided with an article determination device for determining whether the product is non-defective or defective in the preceding stage, wherein a transfer path is provided in the transfer conveyor, and the transfer path is This is a sorting device. The article determination device provided in the front stage on the transport conveyor is, for example, a metal foreign object detection device, an X-ray foreign material detection device, or the like, and is distributed based on information from these. In addition, an article detection device that detects an incoming article in front of the conveyance path and a distribution device control unit are provided in the preceding stage of the conveyance path. An opening / closing flipper having a hinge on one side is provided in the conveying path, and an air nozzle for blowing a compression air downward is provided on the opening / closing flipper. The sorting device control means controls the flipper to be in a “closed” state when a signal determined that the conveyed article is a non-defective product is received, and the article passes through the conveyance path. The conveyance path is controlled to be flat so as to be directed to the subsequent conveyance conveyor. Further, the distribution device control means controls the open / close flipper to be in an “open” state when receiving a signal determined that the conveyed article is defective, and from the air nozzle at a predetermined timing. It is characterized in that control is performed so that the compressed air is blown and the defective product is distributed below the conveyance path.

請求項２における発明は、送り込まれた物品の重量を搬送しながら計量する計量コンベアと、該計量コンベアの前段には物品を搬入する送り込みコンベアと、該送り込みコンベアに到来する物品を検出する物品検出器と、上記計量コンベアの後段には物品を搬出する送り出しコンベアとを備えた重量選別機において、上記の重量選別機には振り分け装置制御手段が設けられており、上記計量コンベアと上記送り出しコンベアとの間には物品を振り分ける搬送通路が設けられ、上記搬送通路には片方がヒンジの開閉フリッパを設けると共に、該開閉フリッパの上部には圧縮エヤーを下方に向けて吹き付けるためのエヤーノズルを設けた構成である。上記の振り分け装置制御手段は、上記計量コンベアによって計量された物品が良品であると判定された信号を受信したとき上記搬送通路の上記開閉フリッパが「閉」の状態となるよう制御し、上記物品が上記搬送通路上を通過して上記送り出しコンベアに向かうように上記搬送通路を平坦となるよう制御する。また上記の振り分け装置制御手段は、上記計量コンベアによって計量された物品が不良品であると判定された信号を受信したとき所定のタイミングで上記開閉フリッパが「開」の状態となるよう制御し、また所定のタイミングで上記エヤーノズルより圧縮エヤーを吹き付けると共に上記不良品となった物品は上記搬送通路より下方に振り分けるよう制御することを特徴とするものである。 The invention according to claim 2 is a weighing conveyor that measures the weight of an article that has been fed in, a feeding conveyor that carries the article in the previous stage of the weighing conveyor, and an article detection that detects the article that arrives at the feeding conveyor. A weight sorter provided with a container and a delivery conveyor for carrying out articles after the weighing conveyor, wherein the weight sorter is provided with a sorting device control means, and the weighing conveyor, the delivery conveyor, A conveyance path for distributing articles is provided between the two, and an opening / closing flipper having a hinge on one side is provided in the conveyance path, and an air nozzle is provided on the upper part of the opening / closing flipper for blowing a compression air downward. It is. The distribution device control means controls the open / close flipper of the transport path to be in a “closed” state when receiving a signal determined that the article weighed by the weighing conveyor is non-defective. Is controlled so as to flatten the transport path so that it passes over the transport path toward the delivery conveyor. The distribution device control means controls the opening / closing flipper to be in an “open” state at a predetermined timing when receiving a signal determined that the article weighed by the weighing conveyor is defective. Further, the compressed air is blown from the air nozzle at a predetermined timing, and the defective article is controlled to be distributed downward from the conveyance path.

つまり計量コンベアの後方に設けた搬送通路は通常は平坦な搬送路であるが、物品を強制的に搬送する機構ではない。計量コンベアで計量された物品が良品の場合、当該物品は計量コンベアによって送り出された搬送力で上記の搬送通路を滑走して更に後段の送り出しコンベアに乗り移る。 That is, the conveyance path provided behind the weighing conveyor is usually a flat conveyance path, but is not a mechanism for forcibly conveying articles. When the article weighed by the weighing conveyor is a non-defective product, the article slides on the conveyance path with the conveyance force delivered by the weighing conveyor and further transfers to the subsequent delivery conveyor.

また一方、計量コンベアによって計量された物品が不良品の場合は、上記搬送通路の開閉フリッパは片方をヒンジとして計量コンベアに向かって上方に開蓋するように傾斜する。つまり「開」の状態で待機しているフリッパに上記の不良品は案内されて搬送通路の下方向かって放出されるが、これだけでは高速で搬送されてくる不良品は下方に放出されにくいので、不良品が上記フリッパに到達する瞬間から圧縮エヤーを吹き付けて確実に下方に放出するものである。 On the other hand, when the article weighed by the weighing conveyor is defective, the opening / closing flipper of the conveyance path is inclined so as to open upward toward the weighing conveyor with one of the hinges as a hinge. In other words, the defective product is guided to the flipper waiting in the “open” state and discharged toward the lower side of the conveyance path, but with this alone, the defective product conveyed at high speed is difficult to be released downward. The compression air is sprayed from the moment when the defective product reaches the flipper and is surely discharged downward.

請求項３においては、前述した振り分け装置は、前記片方がヒンジの開閉フリッパが所定のタイミングで「開」の状態になるとき所定のタイミングで圧縮エヤーを吹き付ける機構であって、上記エヤーノズルから出た圧縮エヤーは開閉フリッパの上から、開閉フリッパに設けられたスリットを通して少なくとも搬送されてきた不良品の先頭部に吹き付けられることを特徴としたものである。 According to a third aspect of the present invention, the above-described sorting device is a mechanism that blows the compression air at a predetermined timing when the opening / closing flipper of the hinge is in an "open" state at a predetermined timing, and the one of the sorting devices comes out of the air nozzle The compression air is characterized by being sprayed from above the opening / closing flipper to at least the leading portion of the defective product that has been conveyed through a slit provided in the opening / closing flipper.

また請求項４においては、前記振り分け装置における前記片方がヒンジの開閉フリッパの構造についての発明である。前記開閉フリッパには、搬送されてくる物品の幅寸法より広いコの字形の切り欠き部が上記開閉フリッパのヒンジをなす方向に設けられていることを特徴としている。 According to a fourth aspect of the present invention, the one side of the sorting apparatus is an invention of a structure of an open / close flipper of a hinge. The opening / closing flipper is characterized in that a U-shaped notch that is wider than the width of the article being conveyed is provided in a direction that forms the hinge of the opening / closing flipper.

請求項５における発明は、前記振り分け装置制御手段の動作について記述したものであり、前記計量コンベアによって計量された物品が不良品と判定された信号を受信したとき、前記開閉フリッパが「開」の状態を開始するタイミングと、上記フリッパが「開」の状態を維持する時間と、上記エヤーノズルから圧縮エヤーを吹き付ける吹き付け開始のタイミングと、圧縮エヤーの吹き付けを持続する時間と、搬送されてきた物品が良品の場合、開閉フリッパを「閉」の状態に戻すタイミングについて、振り分け装置制御手段が前記搬送コンベアまたは送り込みコンベアに設けられた物品検出器の検出信号を受けることによって所定のタイミング及び時間を生成するようにしたことを特徴としている。 The invention according to claim 5 describes the operation of the sorting device control means, and when the signal measured by the weighing conveyor is determined to be defective, the open / close flipper is "open". The timing for starting the state, the time for the flipper to remain in the “open” state, the timing for starting the blowing of the compression air from the air nozzle, the time for continuing the blowing of the compression air, and the conveyed article In the case of a non-defective product, the timing for returning the open / close flipper to the “closed” state is generated by the sorting device control means receiving a detection signal from an article detector provided on the conveyor or infeed conveyor. It is characterized by doing so.

以上のように本発明によれば、例えば計量コンベアから送り出された物品が不良品の場合、振り分け装置の開閉フリッパを「開」の状態で待機させておき、不良品が上記フリッパに到達する瞬間より圧縮エヤーを下方に吹き付けて振り分けの方向性を確実なものとしている。 As described above, according to the present invention, for example, when an article delivered from a weighing conveyor is a defective product, the opening / closing flipper of the sorting device is kept in an open state, and the moment when the defective product reaches the flipper. The compression air is sprayed downward to ensure the direction of sorting.

また、請求項３においては、フリッパに設けられたスリットの上から該スリットを通して、少なくとも搬送されてきた不良品の先頭部に圧縮エヤーを吹き付けることにより、振り分けの方向性を更に確実なものとしている。 According to a third aspect of the present invention, the direction of the sorting is further ensured by blowing a compression air onto at least the leading portion of the defective product conveyed from above the slit provided in the flipper. .

請求項４の発明によれば、片方がヒンジの開閉フリッパには搬送されてくる物品の幅寸法より広いコの字形の切り欠き部を開閉フリッパのヒンジの側に設けたことにより、先に通過した良品の直後にくる不良品について、該開閉フリッパが開蓋する如く開くとき先に通過した良品の後部を該フリッパの開閉ヒンジに近い部分で蹴り上げることがなくなった。つまり今までは処理能力上げると、物品と物品との間隔（搬送間隔）が必然的に狭くなり上記のような先の物品の後部を蹴り上げることがあり高速化への障害でもあったが解消することができた。 According to the fourth aspect of the present invention, the U-shaped notch that is wider than the width of the article conveyed to the opening / closing flipper of the hinge is provided on the hinge side of the opening / closing flipper. With respect to the defective product that comes immediately after the non-defective product, when the open / close flipper is opened so as to open, the rear portion of the non-defective product that has passed first is no longer kicked up near the open / close hinge of the flipper. In other words, up to now, increasing the processing capacity inevitably narrows the distance between articles (conveyance interval), which may cause the rear part of the previous article to kick up, which was an obstacle to speeding up. We were able to.

請求項４の発明においては、振り分け装置制御手段を設けたことにより高速運転における微妙なタイミングについて確実に制御することができる効果がある。因みに例えば１分間に６００個を処理する場合では、物品の長手方向の寸法を６０ｍｍとして、ベルトの搬送速度を９０ｍ／ｍｉｎとしても、物品の搬送ピッチは１５０ｍｍとなり、物品と物品との間隔は９０ｍｍとなる。この間隔を時間にすると０．０６ｓｅｃとなり、これは極めて短時間であるが本発明による振り分け装置では、この間に良品と不良品を確実に振り分けることが可能となった。 In the invention of claim 4, by providing the sorting device control means, there is an effect that the delicate timing in the high speed operation can be surely controlled. For example, when 600 pieces are processed per minute, even if the longitudinal dimension of the article is 60 mm and the belt conveyance speed is 90 m / min, the article conveyance pitch is 150 mm and the distance between the articles is 90 mm. It becomes. When this time interval is 0.06 sec, which is an extremely short time, the sorting device according to the present invention can reliably sort non-defective products and defective products during this time.

本発明の実施の形態について添付図面に基づき説明する。図１は本発明の振り分け装置を主体とした重量選別機の正面から見た概略の構成図である。図２は図１の上から見た平面図である。図１および図２に示すように、１は物品であり送り込みコンベア上に到来している。１ａは不良品と判定された物品、１ｂは良品と判定された物品、２は送り込みコンベア、３は送り込みコンベア駆動手段であり、例えばパルス駆動モータである。４は計量コンベア、５は計量コンベア駆動手段であり、例えばパルス駆動モータである。６は計量センサ、７は振り分け装置制御手段、８は物品検出器、８ａは物品検出器用投光器である。９はガイド板、１０は開閉フリッパ、１０ａは開閉フリッパに設けたスリット、１０ｂは開閉フリッパに設けた切り欠き部、１１は開閉フリッパ駆動手段であり、例えばパルス駆動モータである。１１aは開閉フリッパ駆動軸芯であり両サイドより図示しない軸受けにて枢支されている。これらガイド板９と開閉フリッパ１０が「閉」の状態（図１では「開」の状態を示している）になることによって形成される平坦面は搬送通路である。１２は圧縮エヤーコントローラであり、供給された圧縮エヤーの圧力を所定の圧力に調整する減圧弁やエヤーフィルタ、電磁弁、およびスピードコントローラ等が内蔵されている。１３はエヤーノズル、１４は送り出しコンベア、１５は送り出しコンベア駆動手段であり、例えばパルス駆動モータである。１６はコンベアによる搬送方向を示す矢印、１７は振り分けられた不良品の放出方向を示す矢印である。 Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a schematic configuration diagram seen from the front of a weight sorter mainly composed of a sorting apparatus according to the present invention. FIG. 2 is a plan view of FIG. As shown in FIG. 1 and FIG. 2, 1 is an article and arrives on the infeed conveyor. 1a is an article determined to be defective, 1b is an article determined to be non-defective, 2 is an infeed conveyor, 3 is an infeed conveyor drive means, for example, a pulse drive motor. 4 is a weighing conveyor, 5 is a weighing conveyor driving means, for example, a pulse driving motor. 6 is a weighing sensor, 7 is a sorting device control means, 8 is an article detector, and 8a is an article detector projector. 9 is a guide plate, 10 is an open / close flipper, 10a is a slit provided in the open / close flipper, 10b is a notch provided in the open / close flipper, and 11 is an open / close flipper driving means, for example, a pulse drive motor. Reference numeral 11a denotes an opening / closing flipper drive shaft, which is pivotally supported by a bearing (not shown) from both sides. A flat surface formed by the guide plate 9 and the open / close flipper 10 being in the “closed” state (shown in the “open” state in FIG. 1) is a conveyance path. A compression air controller 12 includes a pressure reducing valve, an air filter, a solenoid valve, a speed controller, and the like that adjust the pressure of the supplied compression air to a predetermined pressure. 13 is an air nozzle, 14 is a delivery conveyor, 15 is a delivery conveyor drive means, for example, a pulse drive motor. 16 is an arrow indicating the conveying direction by the conveyor, and 17 is an arrow indicating the discharge direction of the sorted defective products.

各部の動作について図１および図２に基づいて説明する。運転状態において物品１は送り込みコンベア上に到達している。物品１が前に進み物品検出器８はその到来を検知する。その信号は振り分け装置制御手段７に電送され、物品１は計量コンベア４上にくる、計量コンベア上に来た物品は、物品検出器８にてその到来を検知されており所定のタイミングを経て計量コンベア上を通過する間に重量を計測するようになっている。そしてその結果その物品が目標重量に対して許容値を超えている場合、開閉フリッパ１０が計量コンベア側に向かって開蓋する向きに開き、物品１ａに示すように矢印１７の方向に放出される。もし物品が良品であった場合は、開閉フリッパは「閉」の状態となり平坦面を形成した搬送通路となり、良品１ｂは矢印１６で示すように送り出しコンベアへと搬送される。 The operation of each part will be described with reference to FIGS. In the operating state, the article 1 reaches the infeed conveyor. The article 1 moves forward and the article detector 8 detects its arrival. The signal is transmitted to the distribution device control means 7, and the article 1 is placed on the weighing conveyor 4. The article coming on the weighing conveyor is detected by the article detector 8 and is weighed after a predetermined timing. The weight is measured while passing on the conveyor. As a result, when the article exceeds the allowable value with respect to the target weight, the opening / closing flipper 10 opens in the direction of opening toward the weighing conveyor side, and is released in the direction of the arrow 17 as shown in the article 1a. . If the article is a non-defective product, the open / close flipper is in a “closed” state to form a conveyance path having a flat surface, and the non-defective product 1b is conveyed to the delivery conveyor as indicated by an arrow 16.

つまり物品が不良品であった場合、物品１ａは図１に示すのように開閉フリッパ１０の下側に潜り込むようになるが、物品の到来タイミングに合わせて、開閉フリッパの上部に位置するエヤーノズル１３により開閉フリッパ１０のスリット１０ａを通して圧縮エヤーを物品１ａのほぼ先頭部に吹き付けることにより矢印１７で示す方向に放出されるようになっている。 In other words, when the article is defective, the article 1a enters under the opening / closing flipper 10 as shown in FIG. 1, but the air nozzle 13 located above the opening / closing flipper in accordance with the arrival timing of the article. As a result, the compressed air is blown through the slit 10a of the opening / closing flipper 10 to the substantially leading portion of the article 1a to be discharged in the direction indicated by the arrow 17.

開閉フリッパ１０に設けられたスリット１０ａは細溝の切り欠きとしたが、丸穴を明けたものでも良くこれらを複数設けても良い、該スリットを設ける位置は搬送通路を形成する幅方向の中央部より左右に均等に設けることが望ましい。 The slit 10a provided in the open / close flipper 10 is a notch in a narrow groove, but a round hole may be provided or a plurality of these may be provided. The position where the slit is provided is the center in the width direction that forms the conveyance path. It is desirable to provide it equally on the left and right sides.

次に開閉フリッパ１０に設けられた切り欠き部１０ｂの作用について説明する。図３及び図４に示すように、本発明の振り分け装置に到来した物品が良品である場合は、平坦となった搬送通路上を滑走して送り出しコンベア１４等に進行するが、当該物品が搬送通路上を通過した直後に来る物品が不良品１ａであった場合、開閉フリッパ１０は所定のタイミングで「開」の状態になる。しかし前述したように極めて短い時間間隔で搬送されているので、先に通過した良品１ｂが搬送通路上を完全に通過していない時に開閉フリッパ１０は「開」の状態に作動し始める。この時、先に通過しようとしている物品の後部を開閉フリッパ１０の開閉ヒンジ１１ａに近い部分で蹴り上げる如く持ち上げる（図３参照）。この現象が生じると搬送されている物品の姿勢が乱れ後段の充填装置や箱詰め装置などに不具合を与えることになる。従って本発明では、開閉フリッパ１０の開閉ヒンジ１１ａに近い部分をコの字形に切り欠いた構造になっている（図２参照）。このようにすることによって、０．０６ｓｅｃと言う僅かなタイミングにおいても開閉フリッパ１０が「開」の状態になる時先の物品の後部を蹴り上げることがない（図４参照）。 Next, the operation of the notch 10b provided in the opening / closing flipper 10 will be described. As shown in FIG. 3 and FIG. 4, when the article arrived at the sorting apparatus of the present invention is a non-defective product, it slides on the flat conveyance path and proceeds to the delivery conveyor 14, etc., but the article is conveyed. When the article that comes immediately after passing through the passage is a defective product 1a, the open / close flipper 10 is in an “open” state at a predetermined timing. However, as described above, since it is transported at an extremely short time interval, the open / close flipper 10 starts to operate in the “open” state when the non-defective product 1b that has passed first does not completely pass through the transport path. At this time, the rear part of the article to be passed first is lifted up so as to be kicked up at a portion near the opening / closing hinge 11a of the opening / closing flipper 10 (see FIG. 3). When this phenomenon occurs, the posture of the article being conveyed is disturbed, which causes a problem with the filling device or the boxing device in the subsequent stage. Therefore, in the present invention, the portion close to the open / close hinge 11a of the open / close flipper 10 is cut out in a U-shape (see FIG. 2). By doing so, the rear portion of the article is not kicked up when the open / close flipper 10 is in the “open” state even at a slight timing of 0.06 sec (see FIG. 4).
