Description

吸収性物品を有する物品の整列搬送方法、及び整列搬送装置Method of aligning and conveying articles having absorbent article, and alignment and conveying apparatus
　本発明は、パンティーライナー等の吸収性物品を有する物品の整列搬送方法、及び整列搬送装置に関する。 The present invention relates to a method for aligning and conveying articles having an absorbent article such as a panty liner, and an alignment and conveying apparatus.
　従来、吸収性物品の一例として、下着に取り付けられて下り物等を吸収するパンティーライナー１が知られている（図１Ａを参照）。かかるライナー１は、例えば平面視砂時計形状の薄厚な部材である。そして、同ライナー１は個別包装体１１の形態でユーザーに提供される（図１Ｃ及び図１Ｄを参照）。個別包装体１１は、包装シート５とパンティーライナー１との積層物を同ライナー１の長手方向に四つ折り等の如く複数回折り畳むとともに、かかる折り畳み状態において外形輪郭をなす所定部分にシール部等の接合部７ｓを形成して封止したものであり、その外形形状は、長手方向を有した縦長形状をなしている（図１Ｃを参照）。 Conventionally, as an example of an absorbent article, a panty liner 1 attached to an undergarment to absorb falling objects and the like is known (see FIG. 1A). The liner 1 is, for example, a thin member having an hourglass shape in plan view. The liner 1 is then provided to the user in the form of an individual package 11 (see FIGS. 1C and 1D). The individual wrapping body 11 folds the laminate of the wrapping sheet 5 and the panty liner 1 in the longitudinal direction of the liner 1 by folding it in multiples, etc. The joint portion 7s is formed and sealed, and its outer shape is in the form of a vertically long shape having a longitudinal direction (see FIG. 1C).
　かかる個別包装体１１は、適宜な製造ラインで製造される。そして、製造された個別包装体１１，１１…は、基本的には一列に整列した状態で最終工程の袋詰め工程へと搬送されて（図２を参照）、同工程では、所定数だけ積み重ねられた状態で一つの袋に詰められて出荷される。 The individual package 11 is manufactured on an appropriate manufacturing line. The individual packaging bodies 11, 11 ... produced are conveyed basically to the bagging process of the final process in a state of being aligned in a line (see FIG. 2), and in the process, the predetermined number of stacks are stacked. It is packed in a single bag and shipped.
　但し、諸事情により、かかる袋詰め工程の直前の時点で個別包装体１１が一旦製造ライン外へ排出されることがある。そして、排出された個別包装体１１，１１…のうちで良品１１については、再度製造ラインの袋詰め工程に投入されるが、その際には、ばら積み状態の個別包装体１１，１１…を、上述のように一列に整列した状態で投入する必要がある（図２を参照）。 However, due to various circumstances, the individual wrapping body 11 may be temporarily discharged out of the production line just before the bagging process. And among the discharged individual packages 11, 11 ..., the good product 11 is again put into the bagging process of the production line, but in that case, the individual packages 11, 11 ... in bulk are in the state of As described above, it is necessary to input in a state of being aligned in a row (see FIG. 2).
　ここで、かかるばら積み状態の物品１１，１１…を一列に整列させて搬送する装置としてパーツフィーダ２０が挙げられる（図３を参照）。特許文献１には、このパーツフィーダ２０の一例が開示されている。このパーツフィーダ２０は、無蓋有底略円筒体形状のバケット２１と、バケット２１に振動を付与する振動付与機構４１と、を有している。そして、バケット２１の底面２１ｂには、螺旋状の搬送路２４、すなわち、バケット２１の周方向Ｄｃに進むに従って半径方向Ｄｒの位置が外方に変位した搬送路２４が設けられている。また、搬送路２４における半径方向Ｄｒの外側の縁部２４ｅ１に沿って壁部２６ｅ１が設けられており、同壁部２６ｅ１への当接によって物品１１，１１…の搬送方向Ｄｔが規定されている。 Here, the parts feeder 20 is mentioned as an apparatus which aligns and conveys the articles | goods 11, 11 ... of this bulk-loading state in 1 row (refer FIG. 3). Patent Document 1 discloses an example of the parts feeder 20. The parts feeder 20 has a bucket 21 with a substantially cylindrical shape with no lid and a vibration applying mechanism 41 for vibrating the bucket 21. The bottom surface 21b of the bucket 21 is provided with a spiral transport path 24, that is, the transport path 24 in which the position in the radial direction Dr is displaced outward in the circumferential direction Dc of the bucket 21. Further, a wall 26e1 is provided along the outer edge 24e1 in the radial direction Dr in the transport path 24, and the transport direction Dt of the articles 11, 11 ... is defined by the contact with the wall 26e1. .
　そして、かかるバケット２１内に、ばら積み状態の物品１１，１１…が投入され、且つ、同バケット２１に対して振動付与機構４１から振動が付与されると、バケット２１内の複数の物品１１，１１…が相対滑りや跳躍等をするとともに、搬送路２４の外側の上記壁部２６ｅ１に当接しながら搬送される過程で、各物品１１，１１…は一列に整列され、そして、かかる一列の整列状態で搬送される。 Then, the articles 11, 11... In a stacked state are loaded into the bucket 21 and when vibration is applied to the bucket 21 from the vibration applying mechanism 41, the plurality of articles 11, 11 in the bucket 21 is .. Are transported while being in contact with the wall portion 26e1 outside the transport path 24, while the relative sliding, jumping, etc. are performed, the articles 11, 11... Are aligned in a row, and such a row alignment state It is transported by
　なお、図１０にバケット２１の概略縦断面図を示すが、上記壁部２６ｅ１には、エアーを噴射する噴射口１３１が設けられており、これにより、物品１１，１１が上下方向に複数段重ねの状態で送られることを未然に防いでいる。すなわち、螺旋状の搬送路２４を搬送中に、上記の噴射口１３１からエアーを噴射して、これにより、一段目の物品１１のみを搬送路２４に残しつつ、それよりも上側に重なる物品１１を搬送路２４から吹き落とすようにしている。 In addition, although the schematic longitudinal cross-sectional view of the bucket 21 is shown in FIG. 10, the injection port 131 which injects air is provided in the said wall part 26e1, Thereby, the articles | goods 11 and 11 pile up in multiple steps in the up-down direction. Are prevented from being sent in the state of That is, while the spiral conveyance path 24 is conveyed, air is jetted from the above-mentioned injection port 131, thereby leaving only the article 11 of the first step in the conveyance path 24 and the article 11 overlapping above it. Are blown off from the conveyance path 24.
特開２０００－２４７４３３号JP 2000-247433
　しかし、上記のパンティーライナー１等の吸収性物品の個別包装体１１は、一般に小比重で極めて軽量である。そのため、噴射口１３１を設ける上下方向の位置によっては、複数段重ねの個別包装体１１，１１のうちの二段目以上の個別包装体１１だけでなく、一段目の個別包装体１１までも搬送路２４から吹き落としてしまう恐れがある。 However, the individual packages 11 of absorbent articles such as the above-described panty liner 1 and the like are generally small in specific gravity and extremely lightweight. Therefore, depending on the position in the vertical direction where the injection port 131 is provided, not only the individual package 11 of the second or higher stage among the individual packages 11 and 11 of the plurality of stages but also the individual package 11 of the first stage is also transported There is a risk of blowing down from the road 24.
　例えば、特許文献１には、図１０に示すような内容が開示されている。すなわち、壁部２６ｅ１における噴射口１３１の位置を、二段目の個別包装体１１の真横の位置、すなわち、当該二段目の個別包装体１１が壁部２４ｐ１に当接する当接位置Ｐｃ１１に設定することが開示されている。 For example, Patent Document 1 discloses the content as shown in FIG. That is, the position of the injection port 131 in the wall 26e1 is set to the position just beside the individual package 11 in the second stage, that is, the contact position Pc11 where the individual package 11 in the second stage abuts on the wall 24p1. It is disclosed that.
　しかし、このように設定した場合には、噴射されたエアーは、所定の広がり角度θａで広がりながら飛んでいくことから、一段目の個別包装体１１にもエアーが作用し易く、このことに、前述の個別包装体１１が極めて軽量なことが相俟って、一段目の個別包装体１１も搬送路２４から吹き落とされてしまう。そして、その場合には、次工程への個別包装体１１，１１…の供給能力が低下してしまうことになる。 However, when set in this manner, since the jetted air spreads at a predetermined spread angle θa while flying, the air easily acts on the individual packaging body 11 of the first stage, which means that Due to the extremely light weight of the individual wrapping body 11 described above, the individual wrapping body 11 of the first stage is also blown off from the transport path 24. And in that case, the supply capability of the individual packages 11, 11... To the next process will be reduced.
　本発明は、上記のような従来の問題に鑑みてなされたものであって、その目的は、吸収性物品を有した個別包装体等の物品を一列に整列した状態で次工程へ搬送する際に、複数段重ねの物品のうちの一段目の物品を搬送路に残しながら、複数段重ねの状態を確実に解消することにある。 The present invention has been made in view of the above-described conventional problems, and its object is to transport an article such as an individual package having an absorbent article to the next process in a line. It is another object of the present invention to reliably eliminate the multi-tiered state while leaving the first tier of the multi-tiered articles in the transport path.

　本明細書及び添付図面の記載により、少なくとも以下の事項が明らかとなる。 At least the following matters will be made clear by the present specification and the description of the accompanying drawings.
　吸収性物品を有する複数の物品を搬送部の上面の搬送路に載置することと、
　前記搬送部に振動を付与することによって、前記複数の物品を一列に整列させながら、前記搬送路に沿って搬送することと、を有した吸収性物品を有する物品の整列搬送方法であって、
　前記搬送路の一方の縁部に沿って設けられた壁部に当接しながら、前記物品は、前記搬送路に沿って搬送され、
　前記壁部に設けられた気体の噴射口から前記気体を噴射することにより、上下方向に複数段重ねで搬送される前記物品のうちの二段目以上の物品を前記搬送路の他方の縁部から吹き落し、
　上下二段重ねの物品のうちの二段目の物品が前記壁部に当接する当接位置よりも上側の位置に前記噴射口は設けられていることを特徴とする吸収性物品を有する物品の整列搬送方法である。 Placing a plurality of articles having the absorbent article on the transport path on the upper surface of the transport unit;
And conveying the plurality of articles along the conveyance path while aligning the plurality of articles in a line by applying vibration to the conveyance section.
The article is transported along the transport path while being in contact with a wall provided along one edge of the transport path.
By injecting the gas from the gas injection port provided in the wall portion, the second or more articles of the articles transported in a plurality of stages in the vertical direction in the other stage of the transport path Blow down from
An article having an absorbent article characterized in that the injection port is provided at a position above the contact position where the second-stage article of the two-tiered articles is in contact with the wall portion. It is an alignment conveyance method.
　かかる吸収性物品を有する物品の整列搬送方法によれば、二段目の物品の壁部への当接位置よりも上側の位置に噴射口は設けられている。よって、噴射口から噴射される気体が一段目の物品に概ね当たらないようにしながら、専ら二段目の物品に同気体が当たるようにすることができる。そして、これにより、一段目の物品の搬送に概ね影響しないようにしながら、気体によって二段目以上の物品のみを搬送路から吹き落とすことができる。その結果、物品を一列に整列した状態で次工程へ搬送する際に、複数段重ねの物品のうちの一段目の物品を搬送路に残しながら、複数段重ねの状態を確実に解消可能となる。 According to the method for aligning and conveying articles having such an absorbent article, the injection port is provided at a position above the abutting position to the wall of the second stage article. Therefore, it is possible to make the same gas hit only the second-stage article while preventing the gas jetted from the injection port substantially hitting the first-stage article. And thereby, it is possible to blow off only the articles of the second and higher stages from the transport path by the gas, while substantially not affecting the transport of the articles of the first stage. As a result, when transporting articles to the next process in a state where the articles are aligned in a single row, the multi-tiered state can be reliably eliminated while leaving the first tier of the multi-tiered articles in the transport path. .

The arrangement height from the conveyance path is set to be higher than the arrangement height from the conveyance path of the first injection port. Therefore, when an article overlapped in three or more stages passes the position of the second injection port, an article overlapped on the upper side of the second stage can be blown off from the conveyance path. And thereby, before reaching the position of the 1st jet nozzle in a conveyance way, the article which piled up above the 2nd step is blown off from a conveyance way. Therefore, the first jet port can be specialized exclusively for the blow-off of the second stage article, and as a result, the second jet article can be reliably blown off by the first jet port.

　本実施形態の吸収性物品を有する物品の整列搬送方法、及び整列搬送装置２０は、物品の一例としてのパンティーライナー１の個別包装体１１の整列搬送に供される。 === This embodiment ===
The aligning and conveying method of an article having an absorbent article of the present embodiment and the aligning and conveying apparatus 20 are used for aligning and conveying the individual packages 11 of the panty liner 1 as an example of the article.
　図１Ａは、パンティーライナー１の概略平面図であり、図１Ｂは、図１Ａ中のＢ－Ｂ断面図である。図１Ｃは、パンティーライナー１の個別包装体１１の概略平面図であり、図１Ｄは、上記図１Ｃのパンティーライナー１の個別包装体１１の包装を解いた状態、すなわち包装シート７及びパンティーライナー１の両者を一緒に開いた展開状態の概略平面図である。 FIG. 1A is a schematic plan view of the panty liner 1, and FIG. 1B is a cross-sectional view taken along the line BB in FIG. 1A. 1C is a schematic plan view of the individual package 11 of the panty liner 1, and FIG. 1D is the unwrapped state of the individual package 11 of the panty liner 1 of FIG. 1C, that is, the packaging sheet 7 and the panty liner 1. Is a schematic plan view of the unfolded state in which both are opened together.
　図１Ａ及び図１Ｂに示すように、パンティーライナー１は、パルプ繊維等の液体吸収性素材を所定形状に積層してなる吸収体２を、厚さ方向の両側から液透過性の表面シート３と液不透過性の裏面シート４とで覆った薄厚のシート状部材であり、その平面形状は、例えば略砂時計形状をなしている。なお、同ライナー１の非肌側面をなす裏面シート４の面には、下着への固定に供するずれ止め用接着剤５が塗布されている。また、同ライナー１の使用時まで同接着剤５の粘着力を保護する目的で、ずれ止め用接着剤５を覆って離型シート６が設けられている。かかる離型シート６は包装シート７に強固に接合されており、ライナー１の使用時には、同離型シート６は、包装シート７と一緒にライナー１のずれ止め用接着剤５から速やかに剥がされる。 As shown in FIGS. 1A and 1B, the panty liner 1 comprises an absorbent body 2 formed by laminating a liquid absorbent material such as pulp fibers in a predetermined shape, and a liquid-permeable top sheet 3 from both sides in the thickness direction. It is a thin sheet-like member covered with the liquid-impermeable back sheet 4, and its planar shape is, for example, a substantially hourglass shape. The anti-slip adhesive 5 for fixing to the undergarment is applied to the surface of the back sheet 4 forming the non-skin side of the liner 1. Further, in order to protect the adhesive force of the adhesive 5 until the liner 1 is used, a release sheet 6 is provided to cover the anti-slip adhesive 5. The release sheet 6 is firmly joined to the packaging sheet 7, and when the liner 1 is used, the release sheet 6 is quickly removed from the adhesive 5 for anti-slip of the liner 1 together with the packaging sheet 7. .
　一方、図１Ｄに示すように、同ライナー１の個別包装に供する包装シート７は、例えば平面視矩形状のシートである。そして、同包装シート７上にパンティーライナー１を重ねた状態においては、同シート７の平面サイズは、パンティーライナー１の四辺のうちの少なくとも三辺から外方にはみ出すような平面サイズとされている。例えば、この図１Ｄの例では、パンティーライナー１の幅方向の両側及び同長手方向の一方側においては、包装シート７がはみ出しているが、同長手方向の他方側においては、同ライナー１の方が包装シート７から飛び出している。また、包装シート７には、複数の折り線の一例として第１折り線、第２折り線、及び第３折り線の三本の折り線が、互いに長手方向の異なる位置に設定されている。そして、ライナー１が飛び出した部分に近い順番で、すなわち第１、第２、第３折り線の順番で、ライナー１ごと包装シート７を、長手方向に三回折り畳んでなる図１Ｃの四つ折り状態において、外形輪郭をなす所定部分などにシール部等の接合部７ｓが設けられている。そして、かかる接合部７ｓにより包装シート７は同ライナー１を収容した状態で封止されており、これにて、同図１Ｃの個別包装体１１が形成される。 On the other hand, as shown in FIG. 1D, the packaging sheet 7 used for individual packaging of the liner 1 is, for example, a rectangular sheet in plan view. And, in a state where the panty liner 1 is superimposed on the packaging sheet 7, the plane size of the sheet 7 is a plane size that protrudes outward from at least three sides of the four sides of the panty liner 1. . For example, in the example of FIG. 1D, the packaging sheet 7 protrudes on both sides in the width direction of the panty liner 1 and on one side in the longitudinal direction, but on the other side in the longitudinal direction Is jumping out of the packaging sheet 7. Further, in the packaging sheet 7, three fold lines of a first fold line, a second fold line, and a third fold line as one example of a plurality of fold lines are set at mutually different positions in the longitudinal direction. Then, the four-folded state of FIG. 1C in which the packaging sheet 7 is folded three times in the longitudinal direction together with the liner 1 in the order near the part where the liner 1 pops out, that is, the first, second and third folding lines. In the above, a joint 7s such as a seal is provided at a predetermined part or the like forming an outer contour. And the packaging sheet 7 is sealed in the state which accommodated the same liner 1 by this junction part 7s, and the individual packaging body 11 of FIG. 1C is formed of this.
　なお、図１Ｃに示すように、かかる個別包装体１１は、折り畳んだ方向の寸法Ｗ１１よりも、折り畳んだ方向と直交する方向の寸法Ｌ１１の方が長い縦長形状の薄厚部材となっている。以下、長い寸法Ｌ１１の方向のことを「長手方向」と言い、短い寸法Ｗ１１の方向のことを「短手方向」と言う。また、既述のように、吸収体２はパルプ繊維を主材とし、そして、表面シート３の材料は不織布等であり、更に、裏面シート４や離型シート６、包装シート７の材料も不織布や樹脂フィルム等である。よって、個別包装体１１は小比重で、また極めて軽量であり、その重量は例えば０．５（ｇ）～１０（ｇ）である。 As shown in FIG. 1C, the individual wrapping body 11 is a vertically long thin member in which the dimension L11 in the direction orthogonal to the folded direction is longer than the dimension W11 in the folded direction. Hereinafter, the direction of the long dimension L11 is referred to as "longitudinal direction", and the direction of the short dimension W11 is referred to as "short direction". Further, as described above, the absorbent body 2 is mainly made of pulp fibers, and the material of the top sheet 3 is a non-woven fabric etc. Furthermore, the material of the back sheet 4, the release sheet 6, and the packaging sheet 7 is also non-woven fabric And resin films. Therefore, the individual package 11 has a small specific gravity and is extremely lightweight, and its weight is, for example, 0.5 (g) to 10 (g).
　このようなパンティーライナー１の個別包装体１１は、適宜な製造ラインで製造される。そして、製造された個別包装体１１，１１…は、図２の概略平面図に示すように、一列に整列した状態で最終工程の袋詰め工程へと搬送されて、当該袋詰め工程では、例えば所定数だけ厚さ方向に積み重ねられた状態で一つの袋(不図示)に詰められる。 The individual package 11 of such a panty liner 1 is manufactured on an appropriate manufacturing line. Then, as shown in the schematic plan view of FIG. 2, the manufactured individual packaging bodies 11, 11... Are transported to the bagging process of the final process in a state of being aligned in a row, and in the bagging process, for example It is packed in one bag (not shown) in a state of being stacked in the thickness direction by a predetermined number.
　但し、場合によっては、上記の袋詰め工程に送られる直前に、製造ラインの外に排出されて適宜な回収箱（不図示）に回収されることがある。例えば、製造ラインでのオンライン検査で不良品の可能性有りと判定された個別包装体１１は、回収箱へ送られる。また、袋詰め工程の装置の停止時には、良品であっても、緊急避難的に回収箱へ送られる。 However, in some cases, immediately before being sent to the above-mentioned bagging process, it may be discharged out of the production line and collected in an appropriate collection box (not shown). For example, the individual packages 11 determined to have the possibility of defective products by on-line inspection at the manufacturing line are sent to a collection box. In addition, when the bagging process device is stopped, even non-defective products are sent to the collection box for emergency evacuation.
　従って、回収箱内には良品の個別包装体１１，１１…も含まれており、かかる良品１１，１１…については、再投入ルート経由で製造ラインの袋詰め工程へと送られることになる。但し、その場合には、回収箱の中にあるばら積み状態の個別包装体１１，１１…を、上述の製造ラインでの袋詰め工程への正規の投入ルートと同様に、一列に整列した状態で送らなければならない（図２）。 Accordingly, non-defective individual packages 11, 11... Are also included in the collection box, and the non-defective products 11, 11... Are sent to the bagging process of the manufacturing line via the re-insertion route. However, in that case, the individual packages 11, 11 ... in bulk in the recovery box are aligned in a row, as with the regular input route to the bagging process in the above-mentioned production line. It must be sent (Figure 2).
　そのため、製造ラインには、整列搬送装置としてパーツフィーダ２０も付設されており、同パーツフィーダ２０によって、ばら積み状態の個別包装体１１，１１…を、一列に整列した状態にして送るようにしている。 Therefore, part feeders 20 are also attached to the manufacturing line as an aligning and conveying device, and the individual parts 11, 11... In bulk are sent in an aligned state by the parts feeders 20. .

In FIG. 4, the individual packages 11, 11... Are not shown.
　図３のパーツフィーダ２０は、所謂ロータリー式のパーツフィーダ２０であり、無蓋有底略円筒体形状のバケット２１（搬送部に相当）と、バケット２１に対して所定の振動を付与する振動付与機構４１と、を有している。上記の所定の振動としては、例えば、主に鉛直方向成分を有した振動と、主に搬送方向Ｄｔに沿う水平方向成分を有した振動との両者を合成してなる振動が挙げられる。また、かかる振動の生成は、振動付与機構４１が具備するカム機構や、電磁石とばねとを組み合わせてなる振動体などによって行われる。 The parts feeder 20 of FIG. 3 is a so-called rotary type parts feeder 20, and a vibration applying mechanism which applies predetermined vibrations to the bucket 21 (corresponding to a transport portion) having an open bottom and substantially cylindrical shape. And 41. As the above-mentioned predetermined vibration, for example, a vibration formed by combining a vibration mainly having a vertical direction component and a vibration mainly having a horizontal direction component along the transport direction Dt can be mentioned. Further, the generation of the vibration is performed by a cam mechanism provided in the vibration applying mechanism 41, a vibrating body formed by combining an electromagnet and a spring, or the like.
　一方、バケット２１の底面２１ｂには、螺旋状の搬送路２４、すなわちバケット２１の周方向Ｄｃに進むに従って半径方向Ｄｒの位置が外方に変位した搬送路２４が登り勾配で設けられている。また、図５Ａに示すように、同搬送路２４には、その外側の縁部２４ｅ１に沿って所定高さの壁部２６ｅ１が設けられている。 On the other hand, on the bottom surface 21 b of the bucket 21, a spiral transport path 24, that is, a transport path 24 in which the position in the radial direction Dr is displaced outward as it proceeds in the circumferential direction Dc of the bucket 21 is provided with an ascending slope. Further, as shown in FIG. 5A, the conveyance path 24 is provided with a wall portion 26e1 having a predetermined height along the outer edge portion 24e1.
　よって、バケット２１の底面２１ｂにおける半径方向Ｄｒの中心部２１ｂｃ（貯留部に相当）に向けて、上方からばら積み状態の個別包装体１１が投入されるとともに、同バケット２１に対して上記振動が付与されると、バケット２１内の複数の個別包装体１１，１１…は、上記の壁部２６ｅ１に当接しながら、搬送路２４に対して相対滑りや跳躍等をする。そして、これにより、各個別包装体１１，１１…は、自身の長手方向を順次搬送方向Ｄｔに向けながら、一列に整列して螺旋状の搬送路２４を登っていき、これにて、各個別包装体１１，１１…は同搬送路２４を搬送されていく。そして、かかる一列に整列した状態を維持しながら、最後に、搬送路２４の下流端部２４ｅｎｄに設けられたシュート部２５を滑落し、これにより、適宜なコンベアＣＶ上に落下されて、同コンベアＣＶによって袋詰め工程へ搬送される。 Therefore, the individual packages 11 in a loosely stacked state are loaded from above toward the central portion 21 bc (corresponding to a storage portion) in the radial direction Dr on the bottom surface 21 b of the bucket 21, and the above vibration is applied to the bucket 21. Then, the plurality of individual packaging bodies 11, 11... In the bucket 21 slide relative to the transport path 24 or jump while contacting the wall portion 26e1. And thereby, each individual packaging body 11, 11 ... aligns in a line and climbs up the spiral conveyance path 24 while sequentially orienting its own longitudinal direction in the conveyance direction Dt. The packages 11, 11... Are transported along the transport path 24. Then, while maintaining the aligned state, the chute portion 25 provided at the downstream end 24end of the transport path 24 is finally slid down, thereby being dropped onto an appropriate conveyor CV and the same conveyor It is transported by the CV to the bagging process.
　一方、袋詰め工程では、基本的に一列に整列された個別包装体１１，１１…が、上下方向に二段重ね等の複数段重ねになっていない状態で送られてくる前提で、円滑な受け取りが保証されている。但し、この点につき、希に、図５Ａに示すように、複数段重ねの状態で個別包装体１１，１１がパーツフィーダ２０から搬送される場合があって、このことは、袋詰め工程でのトラブルの一因となる。そのため、複数段重ねの状態で個別包装体１１，１１が袋詰め工程へ搬送されないように、同図５Ａに示すように、同パーツフィーダ２０の上記の壁部２６ｅ１には、エアー(気体に相当)を噴射する噴射口３１が設けられている。そして、この噴射口３１からエアーを噴射することにより、複数段重ねの個別包装体１１，１１のうちで二段目以上の個別包装体１１を搬送路２４から吹き落とすようにしている。 On the other hand, in the bagging process, the individual packaging bodies 11, 11... Basically arranged in a row are sent smoothly in a state where they are not stacked in multiple stages such as two-stage stacking in the vertical direction. The receipt is guaranteed. However, at this point, as shown in FIG. 5A, the individual packaging bodies 11 and 11 may be transported from the parts feeder 20 in a multi-tiered state, as shown in FIG. 5A. It contributes to the trouble. Therefore, as shown in FIG. 5A, the wall portion 26e1 of the parts feeder 20 is air (equivalent to a gas, as shown in FIG. 5A, so that the individual packages 11, 11 are not transported to the bagging process in a plurality of stages. The injection port 31 which injects is provided. Then, air is injected from the injection port 31 to blow off the individual packaging body 11 of the second or more stages from the transport path 24 among the individual packaging bodies 11 and 11 in a plurality of stages.
　すなわち、搬送路２４は、搬送方向Ｄｔと直交する方向（以下、路幅方向Ｄｗと言う）について所定の大きさ（以下、路幅Ｗ２４とも言う）の路面２４ａを本体とし、この路面２４ａの上に、各個別包装体１１，１１…が載置されて搬送されている。そして、路面２４ａの路幅Ｗ２４は、個別包装体１１，１１の短手方向の寸法Ｗ１１よりも若干大きい寸法に設定されている。よって、壁部２６ｅ１の噴射口３１から噴射されたエアーが当たった個別包装体１１は、搬送路２４の路面２４ａから路幅方向Ｄｗの内側、すなわちバケット２１の略半径方向Ｄｒの内側に吹き落とされて、これにより、バケット２１の底面２１ｂの中心部２１ｂｃに戻される。なお、上述のように、バケット２１の半径方向Ｄｒと搬送路２４の路幅方向Ｄｗとは、互いにほぼ同方向を向いている。そのため、以下では、「半径方向Ｄｒの内側」のことを「路幅方向Ｄｗの内側」とも言う。 That is, the transport path 24 has a road surface 24a of a predetermined size (hereinafter, also referred to as a path width W24) in a direction orthogonal to the transport direction Dt (hereinafter, referred to as a path width direction Dw). Each individual packaging body 11, 11 ... is placed and transported. The road width W24 of the road surface 24a is set to be slightly larger than the dimension W11 in the short direction of the individual packages 11,11. Therefore, when the individual package 11 hit by the air injected from the injection port 31 of the wall 26e1 blows down from the road surface 24a of the transport path 24 to the inside of the road width direction Dw, that is, the inside of the bucket 21 in the substantially radial direction Dr. Thus, the central portion 21 bc of the bottom surface 21 b of the bucket 21 is returned. As described above, the radial direction Dr of the bucket 21 and the path width direction Dw of the transport path 24 face in substantially the same direction. Therefore, in the following, "inside of radial direction Dr" is also referred to as "inside of road width direction Dw".
　図４及び図５Ａに示すように、噴射口３１は、壁部２６ｅ１の所定部分に設けられている。この例では、当該所定部分は、搬送路２４における下流側の位置に設定されている。また、噴射口３１は、例えば正円孔であり、そして、路幅方向Ｄｗの内側（バケット２１の半径方向Ｄｒの内側）にエアーを常時噴射している。更に、噴射口３１は、上下二段重ねの個別包装体１１，１１のうちの二段目の個別包装体１１が壁部２６ｅ１に当接する当接位置Ｐｃ１１よりも上方に設定されている。すなわち、噴射口３１のうちの最下端部分３１ｄも、上記の当接位置Ｐｃ１１より上方に位置している。 As shown in FIGS. 4 and 5A, the injection port 31 is provided in a predetermined portion of the wall 26e1. In this example, the predetermined portion is set at a downstream position in the transport path 24. In addition, the injection port 31 is, for example, a round hole, and is constantly injecting air to the inside (inside the radial direction Dr of the bucket 21) of the path width direction Dw. Furthermore, the injection port 31 is set above the contact position Pc11 at which the second-tier individual package 11 of the upper and lower two-tiered individual packages 11 and 11 abuts on the wall 26e1. That is, the lowermost end portion 31 d of the injection port 31 is also positioned above the contact position Pc 11 described above.
　よって、所定の広がり角度θａで略放射状に広がって噴射されるエアーが、二段目の個別包装体１１のみに作用するように、噴射口３１を設定することができる。すなわち、エアーのうちの広がった部分を、一段目の個別包装体１１にほぼ当たらないようにしつつ、同エアーを専ら二段目の個別包装体１１に当たるように設定することができる。そして、これにより、一段目の個別包装体１１を搬送路２４に残したまま、二段目の個別包装体１１のみを確実に搬送路２４の内側の縁部２４ｅ２からバケット２１の底面２１ｂの中心部２１ｂｃに吹き落とすことができる。 Therefore, the injection port 31 can be set so that the air which spreads and radiates substantially radially at the predetermined spread angle θa acts only on the individual packaging body 11 of the second stage. That is, it is possible to set the air to be applied exclusively to the second-tiered individual package 11 while making the spread part of the air substantially not hit the first-tier individualized package 11. And thereby, with the first-stage individual packaging body 11 remaining in the conveyance path 24, only the second-stage individual packaging body 11 is reliably from the inner edge 24e2 of the conveyance path 24 to the center of the bottom surface 21b of the bucket 21 The part 21 bc can be blown off.
　なお、かかる噴射口３１の配置位置の許容範囲の下限位置及び上限位置は、例えば、次のようにして決められる。すなわち、上記の噴射口３１の最下端部分３１ｄが、上記の当接位置Ｐｃ１１と一致する噴射口３１の配置位置を、基準位置とした場合に、当該基準位置から、噴射口３１の位置を徐々に上方へ移動していき、その際に、最下端部分３１ｄが当接位置Ｐｃ１１から外れ始めた位置が、先ず許容範囲の下限位置である。そして、更に噴射口３１の位置を上方へ移動していき、そして、エアーが当たった二段目の個別包装体１１が搬送路２４から落ちなくなり始める位置の手前の位置が、上限位置である。より具体的には、噴射口３１から噴射されたエアーの略放射形状の下端縁部が、二段目の個別包装体１１における溝幅方向Ｄｒの内側の端縁部をかすめるようになった位置が、上限位置である。 The lower limit position and the upper limit position of the allowable range of the arrangement position of the injection port 31 are determined as follows, for example. That is, when the arrangement position of the injection port 31 at which the lowermost end portion 31d of the injection port 31 matches the contact position Pc11 is the reference position, the position of the injection port 31 is gradually increased from the reference position. In this case, the position where the lowermost end 31d starts to deviate from the contact position Pc11 is the lower limit position of the allowable range first. Then, the position of the injection port 31 is further moved upward, and the position in front of the position at which the second stage individual package 11 hit by the air does not fall off the transport path 24 is the upper limit position. More specifically, the lower end edge portion of the substantially radial shape of the air injected from the injection port 31 is a position where the inner end edge portion in the groove width direction Dr in the individual package 11 in the second stage is offset. Is the upper limit position.
　かかるエアーの噴射方向は、水平方向であって、しかも搬送路２４の路幅方向Ｄｗの内側（バケット２１の半径方向Ｄｒの内側）を向いた方向を基本方向とするが、この基本方向から、上下方向及び水平方向に±５°の範囲で傾いていてもよい。例えば、水平方向に噴射した場合に、一段目の個別包装体１１が影響を受けるようであれば、上下方向の上方に多少傾けても良い。このような噴射方向の調整は、実機実験等で吹き落とし状況を観察しながら行われる。 The direction in which the air is jetted is the horizontal direction and the direction facing the inner side of the path width direction Dw of the transport path 24 (the inner side of the radial direction Dr of the bucket 21) is the basic direction. It may be inclined in the range of ± 5 ° in the vertical and horizontal directions. For example, in the case where the individual packaging body 11 in the first stage is affected when spraying in the horizontal direction, it may be slightly inclined upward in the vertical direction. Such adjustment of the injection direction is performed while observing the blow-down situation in an actual machine experiment or the like.
　同様に、エアーの風量（ｍ3／分）及び噴射圧（Ｐａ）等の噴射条件についても、実機実験等を通して決定される。例えば、風量及び噴射圧等を複数水準で変更しながら噴射口３１からエアーを噴射し、そのときの二段目の個別包装体１１の吹き落とされる状況及び一段目の個別包装体１１の搬送状況を観察することにより最適値を見出して、噴射条件は決定される。そして、これにより、二段目の個別包装体１１を確実に落下させながらも、一段目の個別包装体１１の搬送には概ね影響を与えないような最適値に噴射条件を設定することができる。なお、かかる最適値への調整は、例えば減圧弁や圧力調整弁等で噴射口３１へのエアーの供給圧（Ｐａ）を調節することや、噴射口３１の口径（ｍｍ）を調節すること等によって行うことができる。 Similarly, the injection conditions such as the air volume (m 3 / minute) and the injection pressure (Pa) of the air are also determined through actual experiments and the like. For example, air is injected from the injection port 31 while changing the air volume, injection pressure, and the like at a plurality of levels, and the second individual package 11 is blown off and the first individual package 11 is transported The injection conditions are determined by finding the optimum value by observing. And thereby, it is possible to set the injection condition to an optimal value that does not substantially affect the conveyance of the individual package 11 of the first stage while dropping the individual package 11 of the second stage surely. . The adjustment to the optimum value may be performed by, for example, adjusting the air supply pressure (Pa) to the injection port 31 with a pressure reducing valve, a pressure adjustment valve, etc., or adjusting the diameter (mm) of the injection port 31 Can be done by
　また、図５Ａの例では、噴射口３１を、口径が１ｍｍのストレート管３１ｐの管端開口部３１ｐｅで実現している。すなわち、壁部２６ｅ１に形成された貫通孔２６ｅ１ｈにストレート管３１ｐの管端開口部３１ｐｅが通されて、かかる管端開口部３１ｐｅを噴射口３１としているが、何等これに限らない。例えば、ストレート管３１ｐの管端開口部３１ｐｅに別途ノズル（不図示）を取り付けても良い。そして、このようにすれば、エアーの広がり角度θａや風量等の噴射特性を容易に変更することができる。また、噴射口３１の口径も何等１ｍｍに限らず、１ｍｍよりも大きくしても良いし、小さくしても良い。 Moreover, in the example of FIG. 5A, the injection port 31 is implement | achieved by the pipe end opening part 31pe of the straight pipe | tube 31p whose aperture is 1 mm. That is, the pipe end opening 31pe of the straight pipe 31p is passed through the through hole 26e1h formed in the wall 26e1, and the pipe end opening 31pe is used as the injection port 31, but the invention is not limited thereto. For example, a separate nozzle (not shown) may be attached to the pipe end opening 31pe of the straight pipe 31p. And if it does in this way, ejection characteristics, such as air spread angle thetaa and an air volume, can be changed easily. Further, the diameter of the injection port 31 is not limited to 1 mm, and may be larger or smaller than 1 mm.
　なお、同図５Ａに示すように、望ましくは、搬送路２４の路面２４ａ、すなわち、個別包装体１１が載置される面２４ａは、搬送路２４の外側の縁部２４ｅ１の方が、内側の縁部２４ｅ２よりも高さが低くなった勾配θ２４を有していると良い。そして、このようになっていれば、先ず、路面２４ａ上の個別包装体１１を水平方向から傾いた姿勢にして壁部２６ｅ１に寄せることができて、これにより、同個別包装体１１を壁部２６ｅ１に確実に当接させることができる。また、このように個別包装体１１が傾いた姿勢になっていれば、エアーの広がり部分を二段目の個別包装体１１のうちの路幅方向Ｄｗ（バケット２１の半径方向Ｄｒ）の内側の部分にかすらせ易くなって、これにより、一段目の個別包装体１１を残して二段目の個別包装体１１のみを確実に落下させることができる。但し、上記のような勾配θ２４は無くても良く、つまり、路面２４ａは、バケット２１の半径方向Ｄｒに関して水平であっても良く、更に言い換えると、路面２４ａにおける外側の縁部２４ｅ１と内側の縁部２４ｅ２とは、互いに同じ高さであっても良い。 As shown in FIG. 5A, desirably, the road surface 24a of the transport path 24, that is, the surface 24a on which the individual wrapping body 11 is placed, the outer edge 24e1 of the transport path 24 is the inner side. It is preferable to have a slope θ 24 that is lower in height than the edge 24 e 2. And if it is such, first, the individual wrapping body 11 on the road surface 24a can be brought into the posture inclined from the horizontal direction and can be brought close to the wall portion 26e1, whereby the individual wrapping body 11 can be wall portion It can be made to abut on 26e1 reliably. In addition, if the individual wrapping body 11 is in the inclined posture in this way, the spread part of the air is located inside the path width direction Dw (radial direction Dr of the bucket 21) of the individual wrapping body 11 of the second stage. It becomes easy to make a part fade, and, thereby, only the individual packaging body 11 of the second stage can be surely dropped while leaving the individual packaging body 11 of the first stage. However, the slope θ 24 as described above may not be present, that is, the road surface 24 a may be horizontal with respect to the radial direction Dr of the bucket 21, in other words, the outer edge 24 e 1 and the inner edge of the road surface 24 a. The portions 24e2 may have the same height as one another.
　また、図４に示すように、この例では、上記の噴射口３１を第１噴射口３１とした場合に、壁部２６ｅ１における第１噴射口３１の配置位置とは異なる位置に、第２噴射口３２が配置されている。すなわち、同図４に示すように、第１噴射口３１の配置位置よりも搬送方向Ｄｔの上流側の位置に相当する壁部２６ｅ１の部分に第２噴射口３２が配置されている。また、図５Ｂに示す第２噴射口３２の配置位置での搬送路２４の路面２４ａ基準の第２噴射口３２の配置高さｈ３２は、図５Ａに示す第１噴射口３１の配置位置での搬送路２４の路面２４ａ基準の第１噴射口３１の配置高さｈ３１よりも高くされている。より詳しくは、第２噴射口３２の配置位置での路面２４ａからの第２噴射口３２の中心位置Ｃ３２の高さは、第１噴射口３１の配置位置での路面２４ａからの第１噴射口３１の中心位置Ｃ３１の高さｈ３１よりも高くされている。 Further, as shown in FIG. 4, in this example, when the above-described injection port 31 is the first injection port 31, the second injection is performed at a position different from the arrangement position of the first injection port 31 in the wall 26e1. A mouth 32 is arranged. That is, as shown in FIG. 4, the second injection port 32 is disposed at a portion of the wall portion 26e1 corresponding to a position upstream of the arrangement position of the first injection port 31 in the transport direction Dt. Further, the arrangement height h32 of the second injection hole 32 based on the road surface 24a of the transport path 24 at the arrangement position of the second injection hole 32 shown in FIG. 5B is the arrangement position of the first injection hole 31 shown in FIG. The arrangement height h31 of the first injection port 31 based on the road surface 24a of the conveyance path 24 is set higher. More specifically, the height of the center position C32 of the second injection port 32 from the road surface 24a at the arrangement position of the second injection port 32 is the first injection port from the road surface 24a at the arrangement position of the first injection port 31. The height h31 of the center position C31 of 31 is made higher.
　よって、図５Ｂに示すように、仮に三段重ねの個別包装体１１，１１，１１が、未だ、この第２噴射口３２の配置位置まで搬送路２４上に残って搬送されている場合に、当該三段重ねの個別包装体１１，１１，１１が第２噴射口３２の位置を通過する際には、同第２噴射口３２から常時噴射されるエアーによって、二段目よりも上側に重なった個別包装体１１（つまり、三段目の個別包装体１１）を搬送路２４から吹き落とすことができる。そして、これにより、搬送路２４における第１噴射口３１の位置に到達するよりも前の時点で、二段目よりも上側に重なった個別包装体１１（三段目の個別包装体１１）は、搬送路２４から確実に吹き落とされる。そのため、図５Ａの第１噴射口３１を、専ら二段目の個別包装体１１の吹き落とし用に特化させることができて、その結果、第１噴射口３１で二段目の個別包装体１１を確実に吹き落とし可能となる。 Thus, as shown in FIG. 5B, if the three-tiered individual packages 11, 11, 11 are still transported on the transport path 24 to the position where the second jet port 32 is disposed, When the three-tiered individual packages 11, 11, 11 pass through the position of the second injection port 32, they are superimposed on the upper side of the second stage by the air constantly ejected from the second injection port 32. The individual packaging body 11 (that is, the third stage individual packaging body 11) can be blown off from the transport path 24. And thereby, the individual packaging body 11 (third individual packaging body 11) overlapped on the upper side of the second stage before reaching the position of the first injection port 31 in the conveyance path 24 And are reliably blown off from the transport path 24. Therefore, the first injection port 31 of FIG. 5A can be specialized exclusively for the blow-off of the individual packaging body 11 of the second stage, and as a result, the individual packaging body of the second stage with the first injection port 31. It becomes possible to blow down 11 surely.
　かかる第２噴射口３２の実現についても、例えば口径が１ｍｍのストレート管３２ｐの管端開口部３２ｐｅを壁部２６ｅ１の貫通孔２６ｅ１ｈに通すこと等でなされる。なお、管端開口部３２ｐｅにはノズル（不図示）を取り付けても良い。また、エアーの噴射方向は、水平方向で、且つ路幅方向Ｄｗの内側の方向を基本方向とするが、状況に応じて、この基本方向から、上下方向及び水平方向に±１５°の範囲で傾いていてもよい。更に、エアーの風量（ｍ3／分）及び噴射圧（ｋＰａ）等の噴射条件についても実機実験等を通して決定される。例えば、風量及び噴射圧等を複数水準で変更しながら第２噴射口３２からエアーを噴射し、そのときの二段目よりも上側に重なった個別包装体１１の落下状況を観察することにより最適値を見出して、噴射条件は決定される。また、かかる最適値への調整は、例えば減圧弁や圧力調整弁で第２噴射口３２へのエアーの供給圧を調節することや、第２噴射口３２の口径を調節すること等によって行うことができる。 The second injection port 32 is also realized, for example, by passing the pipe end opening 32pe of the straight pipe 32p having a diameter of 1 mm through the through hole 26e1h of the wall 26e1. A nozzle (not shown) may be attached to the pipe end opening 32pe. In addition, the direction of air injection is the horizontal direction and the direction inside the path width direction Dw is the basic direction, but depending on the situation, ± 15 ° in the vertical and horizontal directions from this basic direction. It may be tilted. Furthermore, the injection conditions such as the air volume (m 3 / minute) and the injection pressure (kPa) of the air are also determined through actual experiments and the like. For example, it is optimal by injecting air from the second injection port 32 while changing the air volume, injection pressure, etc. at a plurality of levels, and observing the falling condition of the individual package 11 superimposed on the upper side than the second stage at that time. With the values found, the injection conditions are determined. Further, adjustment to such an optimum value is performed, for example, by adjusting the air supply pressure to the second injection port 32 with a pressure reducing valve or a pressure adjustment valve, adjusting the diameter of the second injection port 32, or the like. Can.
　ところで、図４に示すように、搬送路２４のうちの第１噴射口３１の配置位置からシュート部２５までの間の部分２４ｐ１には、搬送路２４の外側の縁部２４ｅ１だけでなく内側の縁部２４ｅ２にも壁部２６ｅ２が設けられており、これにより、当該部分２４ｐ１は、個別包装体１１をシュート部２５へと案内する誘導路２４ｐ１をなしている。以下、内側の縁部２４ｅ２に設けられた壁部２６ｅ２のことを「内側壁部２６ｅ２」と言い、既述の外側の縁部２４ｅ１に設けられた壁部２６ｅ１のことを「外側壁部２６ｅ１」と言う。 By the way, as shown in FIG. 4, not only the outer edge 24 e 1 of the transport path 24 but also the inner portion thereof in the portion 24 p 1 of the transport path 24 from the arrangement position of the first injection port 31 to the chute portion 25. The edge portion 24 e 2 is also provided with a wall portion 26 e 2, whereby the portion 24 p 1 forms a guiding path 24 p 1 for guiding the individual wrapping body 11 to the chute portion 25. Hereinafter, the wall 26e2 provided in the inner edge 24e2 is referred to as "inner side wall 26e2", and the wall 26e1 provided in the outer edge 24e1 described above is referred to as "outside wall 26e1". Say.
　ここで、仮に、当該誘導路２４ｐ１の入口２４ｐ１ｅに到達した個別包装体１１が、複数段重ねではない一段の状態であったとしても、当該個別包装体１１の長手方向が搬送方向Ｄｔに対して大きく斜めに傾いている場合には、内側壁部２６ｅ２に個別包装体１１が引っ掛かって誘導路２４ｐ１の入口２４ｐ１ｅで詰まってしまう恐れがある。 Here, even if the individual wrapping body 11 that has reached the inlet 24p1e of the guiding path 24p1 is in a state of one step other than multiple stacking, the longitudinal direction of the individual wrapping body 11 is relative to the transport direction Dt. If the individual wrapping body 11 is caught by the inner side wall portion 26e2 when it is largely inclined, there is a possibility that the individual wrapping body 11 may be clogged at the inlet 24p1e of the guiding path 24p1.
　そのため、図４の例では、このような入口２４ｐ１ｅでの個別包装体１１の詰まりを未然に防ぐべく、この入口２４ｐ１ｅよりも若干上流側の位置で、長手方向が搬送方向Ｄｔから大きく斜めに傾いた個別包装体１１を搬送路２４から落下させるように工夫２４ｇが施されている。 Therefore, in the example of FIG. 4, the longitudinal direction is largely inclined obliquely from the transport direction Dt at a position slightly upstream of the inlet 24p1e in order to prevent clogging of the individual package 11 at the inlet 24p1e. A device 24g is provided to cause the individual package 11 to drop from the transport path 24.
　図６は、その工夫２４ｇの説明図であって、誘導路２４ｐ１の入口２４ｐ１ｅの近傍部分を上方から見た概略平面図である。 FIG. 6 is an explanatory view of the device 24g, and is a schematic plan view of the vicinity of the inlet 24p1e of the induction passage 24p1 as viewed from above.
　図６に示すように、搬送路２４における上記入口２４ｐ１ｅよりも若干上流側の位置には、搬送路２４の内側の縁部２４ｅ２側からへこんで路幅Ｗ２４が狭くなった部分２４ｇ（以下、狭路幅部分２４ｇとも言う）が設けられている。そして、この例では、当該狭路幅部分２４ｇの路幅Ｗ２４ｇは、個別包装体１１の短手方向の寸法Ｗ１１と同値に設定されており、これにより、搬送方向Ｄｔから斜めに傾いていない姿勢の個別包装体１１であっても、狭路幅部分２４ｇを通過する際に、個別包装体１１における一部１１ｐが、狭路幅部分２４ｇよりも内側にはみ出すようになっている。詳しくは、搬送路２４の外側壁部２６ｅ１の形状が平面視略円弧状であることから、個別包装体１１の四つの角部１１ｃ，１１ｃ…のうちの路幅方向Ｄｗの外側に位置する２つの角部１１ｃ，１１ｃが外側壁部２６ｅ１の内周面に接触すると、個別包装体１１における路幅方向Ｄｗの内側に位置する辺１１ｐが、狭路幅部分２４ｇにおける内側の縁部２４ｇｅ２よりも内側にはみ出した状態となる。また、かかる狭路幅部分２４ｇの搬送方向Ｄｔの寸法Ｌ２４ｇは、例えば個別包装体１１の長手方向の寸法Ｌ１１よりも長く、同寸法Ｌ１１の二倍の長さよりも短い寸法に設定されている。 As shown in FIG. 6, at a position slightly upstream of the inlet 24p1e in the transport path 24, a portion 24g in which the path width W24 is narrowed from the side of the inner edge 24e2 of the transport path 24 (hereinafter referred to as narrow) A road width portion 24g is also provided. And, in this example, the path width W24g of the narrow path width portion 24g is set to the same value as the dimension W11 in the short direction of the individual wrapping body 11, whereby a posture not inclined obliquely from the transport direction Dt Even in the case of the individual wrapping body 11, when passing the narrow passage width portion 24g, the part 11p of the individual wrapping body 11 protrudes inside the narrow passage width portion 24g. Specifically, since the outer wall 26e1 of the transport path 24 has a substantially arc shape in a plan view, two of the four corners 11c, 11c of the individual package 11 are located outside the path width direction Dw 2 When the two corners 11c and 11c contact the inner peripheral surface of the outer wall 26e1, the side 11p located inside the path width direction Dw in the individual wrapping body 11 is more than the inner edge 24ge2 of the narrow path width portion 24g. It will be in the state where it went out inside. Further, the dimension L24g in the transport direction Dt of the narrow passage width portion 24g is set to, for example, a dimension longer than the dimension L11 in the longitudinal direction of the individual package 11 and shorter than twice the same dimension L11.
　よって、搬送方向Ｄｔから大きく斜めに傾いた個別包装体１１が上記の狭路幅部分２４ｇを通過する際には、同個別包装体１１が、狭路幅部分２４ｇから大きく路幅方向Ｄｗの内側にはみ出した状態となって、これにより、個別包装体１１の重心位置が、狭路幅部分２４ｇの内側の縁部２４ｇｅ２よりも内側にはみ出した状態になり易い。従って、上記の誘導路２４ｐ１の入口２４ｐ１ｅに詰まりそうな程度に大きく傾いた個別包装体１１は、当該狭路幅部分２４ｇの通過中に同狭路幅部分２４ｇから速やかに落下して、これにより、上記入口２４ｐ１ｅでの個別包装体１１の詰まりを未然に防ぐことができる。 Therefore, when the individual wrapping body 11 that is greatly inclined from the transport direction Dt passes through the narrow path width portion 24g, the individual wrapping body 11 largely extends from the narrow path width portion 24g to the inner side in the path width direction Dw. Thus, the position of the center of gravity of the individual wrapping body 11 is likely to protrude to the inner side than the inside edge 24ge2 of the narrow path width portion 24g. Therefore, the individual wrapping body 11 which is largely inclined to the extent that it clogs at the inlet 24p1e of the above-mentioned guideway 24p1 falls quickly from the narrow passage width portion 24g during the passage of the narrow passage width portion 24g. The clogging of the individual package 11 at the inlet 24p1e can be prevented in advance.
　また、複数段重ねの個別包装体１１，１１が当該狭路幅部分２４ｇを通過する際には、仮に搬送方向Ｄｔから斜めに傾いていなくても、当該複数段重ねの個別包装体１１，１１のうちで上側に重なる個別包装体１１の姿勢は、路幅Ｗ２４ｇが狭いことに基づいて、ふらつき易いなど不安定になり易い。よって、当該狭路幅部分２４ｇの通過中に、当該上側に重なる個別包装体１１を一段目の個別包装体１１から速やかに落とすことができて、このことは、前述した複数段重ねの状態の解消に有効に寄与する。 In addition, when the individual packaging bodies 11 and 11 in a plurality of stacks pass through the narrow path width portion 24g, the individual packaging bodies 11 and 11 in the plurality of stacks even if they are not obliquely inclined from the transport direction Dt. Among them, the posture of the individual wrapping body 11 overlapping on the upper side tends to be unstable such as being easily unstable due to the narrowing of the path width W24g. Therefore, during passage of the narrow passage width portion 24g, the individual wrapping body 11 overlapping on the upper side can be quickly dropped from the individual wrapping body 11 of the first stage, which means that Contribute effectively to resolution.
　なお、この例では、狭路幅部分２４ｇの路幅Ｗ２４ｇは、個別包装体１１の短手方向の寸法Ｗ１１と同値とされていたが、何等これに限らない。例えば、個別包装体１１の短手方向の寸法Ｗ１１よりも小さくても良い。但し、個別包装体１１の重心位置が、同個別包装体１１の短手方向の中央に位置していることを考慮すると、望ましくは、狭路幅部分２４ｇの路幅Ｗ２４ｇは、個別包装体１１の短手方向の寸法Ｗ１１の半分の値よりも大きい方が良い。 In this example, the path width W24g of the narrow path width portion 24g is equal to the dimension W11 in the short direction of the individual wrapping body 11, but the invention is not limited thereto. For example, the dimension may be smaller than the dimension W11 in the short direction of the individual wrapping body 11. However, in consideration of the fact that the center of gravity of the individual wrapping body 11 is located at the center in the short direction of the individual wrapping body 11, desirably, the path width W 24 g of the narrow passage width portion 24 g is the individual wrapping body 11. It is better to be larger than the half value of the dimension W11 in the short direction of the.
　また、上述では、狭路幅部分２４ｇの搬送方向Ｄｔの大きさＬ２４ｇは、個別包装体１１の長手方向の寸法Ｌ１１よりも長く、同寸法Ｌ１１の二倍の長さよりも短い寸法に設定されていたが、何等これに限らない。例えば、上記寸法Ｌ１１の二倍の長さよりも長くしても良い。 Further, in the above description, the size L24g of the narrow path width portion 24g in the transport direction Dt is longer than the size L11 in the longitudinal direction of the individual package 11 and shorter than twice the length L11 of the same size L11. However, it is not limited to this at all. For example, the length may be longer than twice the length L11.
　図７に、図６中のＶＩＩ－ＶＩＩ断面図を示す。ここで、望ましくは、狭路幅部分２４ｇの上方に、狭路幅部分２４ｇを通過する個別包装体１１へ向けてエアーを噴射する第３噴射口３３が配置されていると良く、更に望ましくは、当該エアーが、個別包装体１１のうちで狭路幅部分２４ｇからはみ出す部分１１ｐに向けて噴射されていると良い。そして、このようにされていれば、上記の誘導路２４ｐ１の入口２４ｐ１ｅで詰まりそうな程大きく斜めに傾いた個別包装体１１をより確実に狭路幅部分２４ｇから落とすことができるし、更には、複数段重ねの個別包装体１１，１１のうちで上側に重なる個別包装体１１を一段目の個別包装体１１からより確実に落とすこともできる。 FIG. 7 shows a cross-sectional view taken along the line VII-VII in FIG. Here, desirably, a third injection port 33 for injecting air toward the individual wrapping body 11 passing through the narrow passage width portion 24g is preferably disposed above the narrow passage width portion 24g, and more desirably, The air may be jetted toward the portion 11 p of the individual wrapping body 11 protruding from the narrow passage width portion 24 g. And if it is done in this way, it is possible to more reliably drop the individual wrapping body 11 inclined as large as it is likely to be clogged by the inlet 24p1e of the above-mentioned guideway 24p1 from the narrow path width portion 24g, and further The individual wrapping body 11 overlapping on the upper side among the plurality of individual wrapping bodies 11 and 11 stacked on one another can be more reliably dropped from the individual wrapping body 11 of the first stage.
　かかる第３噴射口３３についても、例えば口径が１ｍｍのストレート管３３ｐの管端開口部３３ｐｅ等で実現され、同ストレート管３３ｐは、適宜な不図示のステイ部材を介して壁部２６ｅ１に支持されている。なお、管端開口部３３ｐｅにはノズルを取り付けても良い。また、エアーの風量（ｍ3／分）及び噴射圧（ｋＰａ）等の噴射条件については、実機実験等を通して決定される。例えば、風量及び噴射圧等を複数水準で変更しながら第３噴射口３３からエアーを噴射し、そのときの複数段重ねの個別包装体１１，１１のうちの上側の個別包装体１１の落下状況等を観察することにより最適値を見出して、噴射条件は決定される。また、かかる最適値への調整は、例えば減圧弁や圧力調整弁で第３噴射口３３へのエアーの供給圧を調節することや、第３噴射口の口径を調節すること等によって行うことができる。 The third injection port 33 is also realized by, for example, the pipe end opening 33pe of the straight pipe 33p having a diameter of 1 mm, and the straight pipe 33p is supported by the wall 26e1 via a suitable stay member (not shown). ing. A nozzle may be attached to the tube end opening 33pe. In addition, the injection conditions such as the air volume (m 3 / minute) and the injection pressure (kPa) of air are determined through experiments and the like. For example, air is injected from the third injection port 33 while changing the air volume, the injection pressure, and the like at a plurality of levels, and the falling state of the upper individual packaging body 11 among the individual packaging bodies 11 and 11 in multiple tiers at that time The injection conditions are determined by finding the optimum value by observing the etc. In addition, adjustment to such an optimum value may be performed by adjusting the air supply pressure to the third injection port 33 with, for example, a pressure reducing valve or a pressure adjustment valve, adjusting the diameter of the third injection port, or the like. it can.
　図８Ａ及び図８Ｂは、シュート部２５の説明図である。図８Ａは、図４中のＶＩＩＩ－ＶＩＩＩ断面図であり、図８Ｂは、図８Ａ中のＢ―Ｂ矢視図である。 8A and 8B are explanatory diagrams of the chute portion 25. FIG. 8A is a sectional view taken along line VIII-VIII in FIG. 4, and FIG. 8B is a view taken in the direction of arrows B-B in FIG. 8A.
　この例では、シュート部２５の上方にも別途第４噴射口３４を設け、この第４噴射口３４から搬送方向Ｄｔの下流側に向けてエアーを常時噴射している。そして、このようにしていれば、万一、上下二段重ねの個別包装体１１，１１がシュート部２５にまで到達した場合でも、当該二段重ね状態を速やかに解消することができる。すなわち、二段重ねの個別包装体１１，１１のうちの二段目の個別包装体１１に向けて上方からエアーを噴射することにより、当該二段目の個別包装体１１を、一段目の個別包装体１１よりも搬送方向Ｄｔの下流側に進ませることができて、これにより、上下二段重ねを解消することができる。そして、その結果、袋詰め工程に向けて、二段重ねの個別包装体１１，１１が送られてしまうことを確実に防止できる。 In this example, a fourth injection port 34 is additionally provided above the chute portion 25, and air is constantly injected from the fourth injection port 34 toward the downstream side in the transport direction Dt. And if it does in this way, even when the individual packaging body 11 and 11 of two-tiered upper and lower layers reaches the chute | shoot part 25, the said two-tiered state can be eliminated promptly. That is, by injecting air from above onto the individual package 11 of the second stage among the individual packages 11 and 11 of the two-tiered stack, the individual package 11 of the second stage is the individual vehicle of the first stage It can be made to advance to the downstream side of the conveyance direction Dt rather than the packaging body 11, and, thereby, the upper and lower two-stage overlapping can be eliminated. And as a result, it can prevent reliably that the individual- package bodies 11 and 11 of double-stacking will be sent toward the bagging process.
　図８Ｂに示すように、この例では、シュート部２５における路幅方向Ｄｗの中央位置に上記の第４噴射口３４が設けられていて、これにより、直線状のシュート部２５に沿って二段目の個別包装体１１を搬送方向Ｄｔの下流へ真っ直ぐに押し出し可能とされている。但し、噴射口３４の路幅方向Ｄｗの位置は何等これに限らず、シュート部２５における路幅Ｗ２５の±２０％の範囲で路幅方向Ｄｗの中央位置から端側にずれていても良い。 As shown in FIG. 8B, in this example, the fourth injection port 34 described above is provided at the center position of the chute 25 in the path width direction Dw, whereby a two-stage along the straight chute 25 is provided. The individual package 11 of the eyes can be pushed straight down to the downstream in the transport direction Dt. However, the position of the injection port 34 in the path width direction Dw is not limited to this, and may be shifted from the central position in the path width direction Dw to the end side within ± 20% of the path width W25 in the chute portion 25.
　かかる第４噴射口３４についても、例えば口径が１ｍｍのストレート管３４ｐの管端開口部３４ｐｅ等で実現され、同ストレート管３４ｐは、適宜な不図示のステイ部材を介してシュート部２５の壁部２５ｋなどに支持されている。なお、管端開口部３４ｐｅにはノズルを取り付けても良い。また、エアーの風量（ｍ3／分）、噴射圧（ｋＰａ）、及び噴射方向等の噴射条件については、実機実験等を通して決定される。例えば、風量、噴射圧、及び噴射方向等を複数水準で変更しながら第４噴射口３４からエアーを噴射し、そのときの二段目の個別包装体１１の下流側への進行状況を観察することにより最適値を見出して、噴射条件は決定される。また、風量及び噴射圧の最適値への調整は、例えば減圧弁や圧力調整弁で第４噴射口３４へのエアーの供給圧を調節することや、第４噴射口３４の口径を調節すること等によって行うことができる。 The fourth injection port 34 is also realized by, for example, a pipe end opening 34pe of a straight pipe 34p having a diameter of 1 mm, and the straight pipe 34p is a wall of the chute 25 through an appropriate stay member (not shown). It is supported by 25k etc. A nozzle may be attached to the pipe end opening 34pe. The air volume (m 3 / minute) of the air, the injection pressure (kPa), and the injection conditions such as the injection direction are determined through actual machine experiments and the like. For example, the air is injected from the fourth injection port 34 while changing the air volume, the injection pressure, the injection direction, etc. at a plurality of levels, and the progress of the second stage individual packaging body 11 at that time is observed By finding the optimum value, the injection condition is determined. Further, to adjust the air volume and the injection pressure to the optimum values, for example, adjust the air supply pressure to the fourth injection port 34 by a pressure reducing valve or a pressure adjustment valve, or adjust the diameter of the fourth injection port 34 Etc can be done.
　＝＝＝その他の実施の形態＝＝＝
　以上、本発明の実施形態について説明したが、上記の実施形態は、本発明の理解を容易にするためのものであり、本発明を限定して解釈するためのものではない。また、本発明は、その趣旨を逸脱することなく、変更や改良され得るとともに、本発明にはその等価物が含まれるのはいうまでもない。例えば、以下に示すような変形が可能である。 === Other Embodiments ===
As mentioned above, although embodiment of this invention was described, said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. Further, it goes without saying that the present invention can be modified or improved without departing from the gist thereof, and that the present invention includes equivalents thereof. For example, the following modifications are possible.
　上述の実施形態では、整列搬送装置の一例として、螺旋状の搬送路２４を有したロータリー式のパーツフィーダ２０を開示したが、何等これに限らない。例えば、図９の概略斜視図に示すような、直線状の搬送路２４を有したリニア式のパーツフィーダ２０ａでも良い。詳しくは、かかるパーツフィーダ２０ａは、直線状の搬送路２４を上面に有した搬送部２１と、搬送部２１に対して所定の振動を付与する振動付与機構４１と、を有する。上記所定の振動としては、例えば、主に鉛直方向成分を有した振動と、主に搬送方向Ｄｔに沿った水平方向成分を有した振動との両者を合成してなる振動が挙げられる。また、かかる振動の生成は、振動付与機構４１が具備するカム機構や、電磁石とばねとを組み合わせてなる振動体などによってなされる。 In the above-mentioned embodiment, although the rotary-type parts feeder 20 with the spiral conveyance path 24 was disclosed as an example of the alignment conveyance apparatus, it does not restrict to this at all. For example, as shown in the schematic perspective view of FIG. 9, a linear part feeder 20a having a linear conveyance path 24 may be used. Specifically, the parts feeder 20 a includes a transport unit 21 having a straight transport path 24 on the top surface, and a vibration applying mechanism 41 that applies a predetermined vibration to the transport unit 21. Examples of the predetermined vibration include a vibration obtained by combining a vibration mainly having a vertical direction component and a vibration mainly having a horizontal direction component along the transport direction Dt. In addition, the generation of the vibration is performed by a cam mechanism included in the vibration applying mechanism 41, a vibrator including a combination of an electromagnet and a spring, or the like.
　一方、直線状の搬送路２４は、搬送方向Ｄｔの下流側に進むに従って高さが高くなった登り勾配を有している。また、同搬送路２４には、その一方の縁部２４ｅ１に沿って所定高さの壁部２６ｅ１が設けられている。 On the other hand, the linear conveyance path 24 has a rising slope whose height is increased as it progresses to the downstream side in the conveyance direction Dt. Further, a wall portion 26e1 having a predetermined height is provided along the one edge 24e1 of the conveyance path 24.
　よって、上記搬送部２１に対して振動が付与されると、搬送部２１の搬送路２４に載置された各個別包装体１１，１１…は、上記の壁部２６ｅ１に当接しながら、搬送路２４に対して相対滑りや跳躍等をする。そして、これにより、各個別包装体１１，１１…は自身の長手方向を順次搬送方向Ｄｔに向けながら、一列に整列して搬送路２４を登っていき、これにて、各個別包装体１１，１１…は同搬送路２４を搬送されていく。また、上記壁部２６ｅ１には、噴射口３１が設けられている。そして、噴射口３１は、上下二段重ねの個別包装体１１，１１のうちの二段目の個別包装体１１が壁部２６ｅ１に当接する当接位置Ｐｃ１１よりも上側の位置に設定されている。よって、噴射口３１から噴射されるエアーが一段目の個別包装体１１に概ね当たらないようにしながら、専ら二段目の個別包装体１１にエアーが当たるようにすることができる。そして、これにより、一段目の個別包装体１１の搬送に概ね影響しないようにしながら、エアーによって二段目の個別包装体１１のみを搬送路２４の他方の縁部２４ｅ２から吹き落とすことができる。 Therefore, when vibration is applied to the transport unit 21, the individual packaging bodies 11, 11 ... placed on the transport path 24 of the transport unit 21 contact the wall portion 26e1 while the transport path Slide or jump relative to 24. Then, the individual packages 11, 11... Are aligned in a line and climb up the transport path 24 while sequentially orienting the longitudinal direction of the individual packages 11, 11,. 11 ... are transported through the transport path 24. Moreover, the injection port 31 is provided in the said wall part 26e1. The injection port 31 is set at a position above the contact position Pc11 at which the second-tier individual packaging body 11 of the two-tiered individual packaging bodies 11 and 11 abuts on the wall 26e1. . Therefore, air can be made to hit the individual packaging body 11 of the second stage exclusively while preventing the air jetted from the injection port 31 from substantially hitting the individual packaging body 11 of the first stage. And thereby, it is possible to blow off only the individual packaging body 11 of the second stage from the other edge 24 e 2 of the conveyance path 24 by air, while substantially not affecting the conveyance of the individual packaging body 11 of the first stage.
　上述の実施形態では、整列搬送対象の物品の一例として個別包装体１１を例示したが、何等これに限らない。すなわち、整列搬送対象の物品が、包装シート７で包装されていない非包装状態の吸収性物品であっても良い。また、かかる吸収性物品がパンティーライナー１以外であっても良く、例えば、生理用ナプキンやタンポン、使い捨ておむつ等であっても良い。 In the above-mentioned embodiment, although the individual wrapping body 11 was illustrated as an example of the article for alignment conveyance, it is not restricted to this at all. That is, the article to be aligned and transported may be an absorbent article in a non-packaged state not packaged by the packaging sheet 7. Further, the absorbent article may be other than the panty liner 1, and may be, for example, a sanitary napkin, a tampon, a disposable diaper or the like.
　上述の実施形態では、第１乃至第４噴射口３１，３２，３３，３４から噴射する気体の一例としてエアーを例示したが、何等これに限らない。すなわち、噴射対象の個別包装体１１に対して化学的影響を及ぼさない気体であれば、用いることができて、例えば、窒素等を用いても良い。 Although air was illustrated as an example of the gas injected from the 1st thru | or 4th injection port 31, 32, 33, 34 in the above-mentioned embodiment, it does not restrict to this at all. That is, any gas that does not have a chemical effect on the individual package 11 to be jetted can be used. For example, nitrogen or the like may be used.
