Description

この発明は、缶,瓶商品販売用の自動販売機に搭載したサーペンタイン式商品ラックに関し、詳しくはラック内に配備した商品通路幅調整用の可動側板とラック側板との間を連繋する平行リンク機構のリンク構造に係わる。   The present invention relates to a serpentine type product rack mounted on a vending machine for selling cans and bottles, and more specifically, a parallel link mechanism for connecting a movable side plate for adjusting a product passage width and a rack side plate arranged in the rack. Related to the link structure.

頭記サーペンタイン式商品ラックの商品通路幅を商品の長さに応じて規制する調整手段として、ラックの商品通路に可動側板を追加配備し、該可動側板に平行リンク機構を連結して垂直姿勢を保ったまま左右へ移動可能に支持したサーペンタイン式商品ラックが知られており(例えば、特許文献1参照)、次にその従来構造を図3〜図6に示す。
まず、図3,図4において、1は左右に対向して立設したラック側板、2はラック側板1の間に架設して前後面に敷設した円弧状のトラックレール、3は前後面に並ぶトラックレール2の間に画成した上下方向の蛇行状商品通路、4は商品通路3に連ねてラック上部の前方に敷設した商品投入用のトップトレー、5はラック側板2の間の全幅Aに対して商品通路3の通路幅Bを商品6の長さサイズLに合わせて規制する可動側板、7は左右のラック側板1の間に架設して前記可動側板5を吊り下げ、該可動側板5を左右方向(矢印P)へ移動可能に案内支持するガイド棒、8は可動側板5と一方(左側)のラック側板1との間に介装して相互連結した平行リンク機構のリンクである。
As an adjustment means to regulate the product passage width of the serpentine type product rack according to the length of the product, a movable side plate is additionally provided in the product passage of the rack, and a parallel link mechanism is connected to the movable side plate so that the vertical posture is maintained. A serpentine-type product rack that is supported so as to be movable left and right while being held is known (see, for example, Patent Document 1). Next, the conventional structure is shown in FIGS.
First, in FIGS. 3 and 4, 1 is a rack side plate erected on the left and right sides, 2 is an arc-shaped track rail laid between the rack side plates 1 and laid on the front and rear surfaces, and 3 is arranged on the front and rear surfaces. An up-and-down meandering product passage defined between the track rails 2, 4 is a product introduction top tray that is connected to the product passage 3 and laid in front of the rack upper portion, and 5 is a full width A between the rack side plates 2. On the other hand, a movable side plate 7 that regulates the passage width B of the product passage 3 in accordance with the length size L of the product 6, and 7 is suspended between the left and right rack side plates 1 to suspend the movable side plate 5. 8 is a link of a parallel link mechanism that is interposed between the movable side plate 5 and one (left side) rack side plate 1 so as to be movable in the left-right direction (arrow P).

前記平行リンク機構は上下一対のリンク8とリンク連結板(不図示)との組立体からなり、後記のようにリンク8はその両端に形成したヒンジ軸をそれぞれラック側板1,可動側板5に形成した連結フランジ1a,5aの軸穴に嵌挿して傾動可能に連結されている。
ここで、平行リンク機構の構成部材であるリンク8は、所要の機械的強度を確保させるために、従来では例えば板厚t=1.6mmの鋼板(素材板)からプレスにより打ち抜いたブランクに部分的な曲げ加工を施して作製したものを採用しており、図5(a),(b)で示すようにリンク8の両端にはヒンジ軸8a,8b(断面形状が四角形)、および組立の際に利用する逃げ溝(切込み溝)8cが形成され、さらに下端側のヒンジ軸8aにはラック側板1に軸支連結した組立状態でヒンジ軸8aの抜けを阻止する突起状の抜け止めストッパ8dが前記逃げ溝8cと反対側の部位に形成されている。また、図6(a),(b)は前記平行リンク機構のリンク8とラック側板1,可動側板5との連結構造を表す図で、ラック側板1にはリンク8との連結部位に切欠いた縦長な窓穴1cの左右側縁に連結フランジ1a((a)図参照)を切り起こし、該連結フランジ1aの壁面に穿孔した軸穴1bに先記したヒンジ軸8aの両端を左右に片寄りさせながら嵌挿して連結している。
The parallel link mechanism comprises an assembly of a pair of upper and lower links 8 and a link connecting plate (not shown). As will be described later, the link 8 has hinge shafts formed at both ends thereof on the rack side plate 1 and the movable side plate 5, respectively. The connecting flanges 1a and 5a are inserted into the shaft holes and connected so as to be tiltable.
Here, in order to ensure the required mechanical strength, the link 8 which is a constituent member of the parallel link mechanism is partly formed in a blank that has been punched out by a press from a steel plate (material plate) having a thickness of t = 1.6 mm. As shown in FIGS. 5 (a) and 5 (b), hinge shafts 8a and 8b (cross-sectional shape is a square) are attached to both ends of the link 8, as shown in FIGS. An escape groove (cut-out groove) 8c used at the time is formed, and the hinge shaft 8a on the lower end side is a protrusion-shaped stopper 8d that prevents the hinge shaft 8a from coming off in an assembled state in which the hinge shaft 8a is pivotally connected to the rack side plate 1. Is formed at a site opposite to the escape groove 8c. 6 (a) and 6 (b) are views showing a connection structure between the link 8 of the parallel link mechanism and the rack side plate 1 and the movable side plate 5. The rack side plate 1 is notched at a connection portion with the link 8. FIG. The connecting flange 1a (see FIG. (A)) is cut and raised at the left and right side edges of the vertically long window hole 1c, and both ends of the hinge shaft 8a described above in the shaft hole 1b drilled in the wall surface of the connecting flange 1a are shifted to the left and right. It is inserted and connected.

一方、可動側板5にはその長手方向に沿って板面中央に形成したチャンネル状凹溝部の側縁から切り起こした連結フランジ5a((b)図参照)に上下方向の長穴5bを開口するとともに、上下一対のリンク8の相互間を軸支連結する断面コ字形のリンク連結板9を前記凹溝部に沿わせてスライド可能に敷設し、該リンク連結板9の左右側壁に穿孔した軸穴,および可動側板5の連結フランジ5aに開口した前記長穴5bの双方に跨がってリンク8のヒンジ軸8bの両端を嵌挿して連結している。なお、平行リンク機構の組立状態では、リンク8の下端側ヒンジ軸8aに形成したストッパ8dがラック側板1の連結フランジ1aの内壁面に乗り上げてヒンジ軸8aが軸穴1bから抜け出るのを阻止する。   On the other hand, the movable side plate 5 is provided with a vertical hole 5b in a connecting flange 5a (see FIG. 5 (b)) cut and raised from the side edge of the channel-shaped concave groove formed in the center of the plate surface along the longitudinal direction. In addition, a link connecting plate 9 having a U-shaped cross-section that supports and connects the pair of upper and lower links 8 is slidably laid along the concave groove portion, and a shaft hole drilled in the left and right side walls of the link connecting plate 9 , And both ends of the hinge shaft 8b of the link 8 are inserted and connected across both the elongated holes 5b opened in the connecting flange 5a of the movable side plate 5. In the assembled state of the parallel link mechanism, the stopper 8d formed on the lower end hinge shaft 8a of the link 8 rides on the inner wall surface of the connecting flange 1a of the rack side plate 1 and prevents the hinge shaft 8a from coming out of the shaft hole 1b. .

上記の構成で、商品6の長さサイズLに合わせてラックの商品通路幅Bを規制するように可動側板5をガイド棒7に沿って移動すると、これに従動して平行リンク機構のリンク8がラック側板1に連結したヒンジ軸8aを支点に傾動して可動側板5を垂直姿勢に保持する。この際に、リンク8の上端側ヒンジ軸8bは可動側板5の連結フランジ5aに開口した長穴5bに沿ってスライド変位する。
特開2003−223676公報
In the above configuration, when the movable side plate 5 is moved along the guide bar 7 so as to regulate the product passage width B of the rack in accordance with the length size L of the product 6, the link 8 of the parallel link mechanism is driven accordingly. Tilts the hinge shaft 8a connected to the rack side plate 1 as a fulcrum to hold the movable side plate 5 in a vertical posture. At this time, the hinge shaft 8b on the upper end side of the link 8 slides and displaces along the elongated hole 5b opened in the connecting flange 5a of the movable side plate 5.
JP 2003-223676 A

ところで、前記平行リンク機構を構成する従来構造のリンク8には、機能面で可動側板5の移動操作性を低下させる問題がある。すなわち、板厚の厚い鋼板(素板)からプレス打ち抜きして作製したリンク8のヒンジ軸8a,8bは断面形状が四角形のままである。このために、先記のように商品6の長さサイズLに合わせて移動操作する可動側板5の動きで傾動する平行リンク機構のリンク8は、そのヒンジ軸8bの角部が可動側板5の連結フランジ5aに形成した長穴5bを変位することになり、このままでは摺動抵抗により可動側板5を手動操作でスムーズに移動することが困難となる。そこで、従来ではヒンジ軸8a,8bにグリースなどの潤滑剤を塗布して対処しているが、自動販売機の長期使用の間にはグリースを塗り替え作業を要するなどメンテナンス性にも問題がある。   By the way, the link 8 of the conventional structure that constitutes the parallel link mechanism has a problem that the moving operability of the movable side plate 5 is lowered in terms of function. That is, the hinge shafts 8a and 8b of the link 8 produced by press punching from a thick steel plate (element plate) have a square cross-sectional shape. For this reason, the link 8 of the parallel link mechanism that is tilted by the movement of the movable side plate 5 that is moved and operated in accordance with the length size L of the product 6 as described above has the corner portion of the hinge shaft 8b of the movable side plate 5. The long hole 5b formed in the connecting flange 5a is displaced, and it is difficult to move the movable side plate 5 smoothly by manual operation due to sliding resistance. Therefore, conventionally, a lubricant such as grease is applied to the hinge shafts 8a and 8b to cope with this problem. However, there is a problem in maintainability such as repainting of grease during long-term use of the vending machine.

そのほか、リンクの所要強度を確保するために板厚の厚い鋼板(板厚1.6mm)が必要で、そのためにコスト面でも材料費が部品コストを押し上げる問題がある。
この発明は上記の点に鑑みなされたものであり、可動側板がスムーズに移動できるよう操作性を改善し、併せて鋼板の板厚ダウンにより部品コストの低減化が図れるように平行リンク機構のリンク構造を改良して構成した自動販売機のサーペンタイン式商品ラックを提供することを目的とする。
In addition, in order to ensure the required strength of the link, a thick steel plate (plate thickness 1.6 mm) is required, and thus there is a problem that the material cost increases the component cost in terms of cost.
The present invention has been made in view of the above points, and improves the operability so that the movable side plate can move smoothly, and at the same time, the link of the parallel link mechanism so that the component cost can be reduced by reducing the plate thickness of the steel plate. An object of the present invention is to provide a vending machine serpentine product rack having an improved structure.

上記目的を達成するために、この発明によれば、左右に対向して立設したラック側板の間に画成した蛇行状の商品通路に横置姿勢の商品を積み上げ収納した自動販売機のサーペンタイン式商品ラックであって、前記商品通路に沿ってその通路横幅を商品の長さサイズに合わせて規制する可動側板を配し、該可動側板と一方のラック側板との間に鋼板製になる上下一対のリンクとリンク連結板を組合せた平行リンク機構を架け渡して可動側板を垂直姿勢に支持したものにおいて、前記リンクが、薄鋼板から打ち抜いたブランクの両端にカール曲げ加工を施してラック側板および可動側板に枢支連結するヒンジ軸を形成するとともに、ブランクの長手方向に沿ってその左右側縁に曲げ絞り加工を施して補強フランジを形成した構造になり、かつ、リンクの両端に形成したヒンジ軸のうち、ラック側板と連結する側のヒンジ軸上に、ブランクの突起形状を折り曲げ加工して抜け止め用ストッパを形成したことを特徴とする。 In order to achieve the above object, according to the present invention, a serpentine type vending machine in which products in a horizontal position are stacked and stored in a meandering product passage defined between rack side plates erected on the left and right sides. A product rack comprising a movable side plate that regulates the width of the passage along the product passage according to the length size of the product, and a pair of upper and lower parts made of steel plates between the movable side plate and one rack side plate. In the case where the movable side plate is supported in a vertical posture by spanning a parallel link mechanism combining the link and the link connecting plate, the link is subjected to curl bending at both ends of the blank punched out from the thin steel plate, and the rack side plate and the movable plate. to form a hinge axis pivotally connected to the side plate, the result on the left and right side edges in the bending diaphragm structure formed reinforcing flange giving the process along the longitudinal direction of the blank, and, Of the hinge shaft formed at both ends of the link, on the side of the hinge shaft connecting the rack side plates, characterized by forming the retaining stopper omission by bending the projection-shaped blank.

上記構成により、リンクの両端にカール曲げ加工で形成した断面円形のヒンジ軸は、板厚の厚い鋼板からブランクを打ち抜き加工して形成した断面角形のヒンジ軸と比べて軸受穴との間の摺動抵抗が大幅に低減する。これにより、商品の長さサイズに合わせてラックの商品通路幅を規制するように可動側板を移動する際の操作性が格段に向上する。
また、リンクの左右側縁に沿って補強フランジを起立形成したことで、薄板の鋼板でもリンクの必要強度を確保でき、これにより鋼板の板厚ダウン化が可能となって材料費のコストダウンが図れる。
With the above configuration, the hinge shaft with a circular cross-section formed by curl bending at both ends of the link is less slid between the bearing hole than the hinge shaft with a square cross-section formed by punching a blank from a thick steel plate. Dynamic resistance is greatly reduced. Thereby, the operativity at the time of moving a movable side plate so that the merchandise passage width of a rack may be regulated according to the length size of a merchandise improves markedly.
In addition, since the reinforcing flanges are erected along the left and right side edges of the link, the required strength of the link can be ensured even with a thin steel plate, which can reduce the plate thickness and reduce the material cost. I can plan.

以下、この発明の実施の形態を図1,図2に示す実施例に基づいて説明する。なお、図1は平行リンク機構の構成部材であるリンク単独の構造図、図2はリンクの下端側ヒンジ軸周辺の連結部分を表す補足説明図で、各図において図5に対応する部材には同じ符号を付している。
この実施例によるリンク8の形状,機能は図5に示した従来のリンクと基本的に同様であるが、その構造および製法が従来品と異なる。すなわち、図1(a),(b)に示す実施例のリンク8は板厚tが0.7mm(従来のリンクは板厚t=1.6mm)の薄鋼板製で、その上下両端にはカール曲げ加工(P曲げ加工)して円形に縁巻きしたヒンジ軸8a,8b、逃げ溝8c、および下端側のヒンジ軸8aの軸上(逃げ溝8cと反対側)にヘアピン状に折り曲げ加工した抜け止めストッパ8dが形成され、さらにリンクの長手方向に沿って左右側縁には曲げ絞り加工したL形の補強フランジ8eが起立形成されており、このリンク8は次記のような方法で製作される。まず、板厚t=0.7mmの薄鋼板(素板)から図1(c)に示す形状のブランク8Aをプレス加工により打ち抜く。次に、このブランク8Aに対して上下両端部8A−1,8A−2にカール曲げ加工(P曲げ加工)を施して断面円形状のヒンジ軸8a,8bを形成する。また、下端部8A−1から突き出た突起形状部8A−3をヘアピン状に折り曲げ加工して抜け止めストッパ8dを形成する。さらに、ブランクの長手方向に沿った左右側縁部8A−4に曲げ絞り加工を施してL形状に起立する補強フランジ8eを形成し、これで図1(a),(b)に示すリンク8が完成する。
Embodiments of the present invention will be described below based on the examples shown in FIGS. 1 is a structural diagram of a single link, which is a component of the parallel link mechanism, and FIG. 2 is a supplementary explanatory diagram showing a connection portion around the lower end hinge shaft of the link. In each figure, members corresponding to FIG. The same reference numerals are attached.
The shape and function of the link 8 according to this embodiment are basically the same as those of the conventional link shown in FIG. 5, but the structure and manufacturing method thereof are different from those of the conventional product. That is, the link 8 of the embodiment shown in FIGS. 1 (a) and 1 (b) is made of a thin steel plate having a thickness t of 0.7 mm (the conventional link has a thickness t = 1.6 mm). The hinge shafts 8a and 8b, the escape groove 8c, and the hinge shaft 8a on the lower end side (on the opposite side of the escape groove 8c) were bent into a hairpin shape by curl bending (P-bending). A stopper 8d is provided, and an L-shaped reinforcing flange 8e that is bent and drawn is erected on the left and right edges along the longitudinal direction of the link. The link 8 is manufactured by the following method. Is done. First, a blank 8A having a shape shown in FIG. 1C is punched out by press working from a thin steel plate (element plate) having a thickness t = 0.7 mm. Next, the upper and lower ends 8A-1 and 8A-2 are subjected to curl bending (P bending) on the blank 8A to form hinge shafts 8a and 8b having circular cross sections. Further, the protrusion-shaped portion 8A-3 protruding from the lower end portion 8A-1 is bent into a hairpin shape to form a stopper stopper 8d. Further, the left and right side edge portions 8A-4 along the longitudinal direction of the blank are subjected to bending drawing to form a reinforcing flange 8e standing up in an L shape, and the link 8 shown in FIGS. 1 (a) and 1 (b). Is completed.

なお、図2(a)はヒンジ軸8aおよびその周辺部の形状を表す斜視図である。また、図2(b)はリンク8のヒンジ軸8aをラック側板1の連結フランジ1aに穿孔した軸穴1bに軸支連結した状態を表す側面図で、ヒンジ軸8aの背後側に突き出した抜け止めストッパ8dが連結フランジ1aの壁面に当接してヒンジ軸8aの脱落を阻止している。すなわち、抜け止めストッパ8dは、図1に示すように、ブランク8Aに突起形状部8A−3を打ち抜き、これをヘアピン状に折り曲げ加工される。この場合、当該折り曲げにより前記突起形状部8A−3が無くなった箇所には逃げ溝8cに相当する大きな空白域が生じ、抜け止めストッパ8dが無い場合(図1の(b)の破線)には前記空白域が逃げ溝となってヒンジ軸8aが脱落してしまうおそれがあるが、抜け止めストッパ8dが連結フランジ1aの壁面に当接することによりストッパとなってヒンジ軸8aの脱落が阻止される。
上記構造のリンク8は、従来のリンクよりも板厚の薄い薄鋼板で作られているが、左右側縁に補強フランジ8eを形成したことにより、強度的には平行リンク機構のリンクに要求される曲げ強度を確保できる。これにより、リンク8の素板である鋼板の板厚ダウン化が可能となって材料費のコストダウンが図れる。
2A is a perspective view showing the shape of the hinge shaft 8a and its peripheral portion. FIG. 2B is a side view showing a state in which the hinge shaft 8a of the link 8 is pivotally connected to a shaft hole 1b drilled in the connecting flange 1a of the rack side plate 1, and is a projection protruding to the rear side of the hinge shaft 8a. A stop stopper 8d abuts against the wall surface of the connecting flange 1a to prevent the hinge shaft 8a from dropping off. That is, as shown in FIG. 1, the stopper stopper 8d is formed by punching the protrusion 8A-3 into the blank 8A and bending it into a hairpin shape. In this case, a large blank area corresponding to the escape groove 8c is generated at the location where the projection-shaped portion 8A-3 is eliminated by the bending, and when there is no stopper 8d (broken line in FIG. 1B). Although there is a possibility that the blank area becomes a relief groove and the hinge shaft 8a falls off, the stopper 8d comes into contact with the wall surface of the connecting flange 1a to prevent the hinge shaft 8a from dropping off. .
The link 8 having the above structure is made of a thin steel plate having a thickness smaller than that of the conventional link. However, the reinforcement flange 8e is formed on the left and right side edges, so that the link 8 of the parallel link mechanism is required in terms of strength. Bending strength can be secured. As a result, it is possible to reduce the thickness of the steel plate that is the base plate of the link 8 and to reduce the material cost.

また、リンク8の両端にカール曲げして形成したヒンジ軸8a,8bは、図5に示した従来の断面角形とは異なり断面形状が円形である。これにより、リンク8を図4で示すように商品ラックのラック側板1,可動側板5に連結した状態で、可動側板5の移動操作に伴いリンク8のヒンジ軸8a,8bとラック側板1の連結フランジ1aに穿孔した軸穴1b、および可動側板5の連結フランジ5aに開口した長穴5bとの間に作用する摺動抵抗は従来の断面角形のヒンジ軸と比べて格段に減少する。したがって、従来のように軸受部にグリースなどの塗布する必要なしに可動側板5をスムーズに移動操作てその操作性が向上する。   Further, the hinge shafts 8a and 8b formed by curling at both ends of the link 8 have a circular cross-sectional shape, unlike the conventional square cross section shown in FIG. As a result, the link 8 is connected to the rack side plate 1 and the movable side plate 5 of the product rack as shown in FIG. 4, and the hinge shafts 8 a and 8 b of the link 8 are connected to the rack side plate 1 in accordance with the moving operation of the movable side plate 5. The sliding resistance acting between the shaft hole 1b drilled in the flange 1a and the long hole 5b opened in the connecting flange 5a of the movable side plate 5 is remarkably reduced as compared with a conventional hinge shaft having a square cross section. Therefore, the movable side plate 5 can be smoothly moved and operated without the need to apply grease or the like to the bearing portion as in the prior art, thereby improving the operability.
