Description

本発明は、メダル・コイン又は重量ある小物を直線的又は湾曲した搬送路でも搬送できるベルトコンベヤ装置であり、主として遊技店における複数の遊技機とメダル貸し機が連設された遊技島でメダルを搬送するために用いられるベルトコンベヤ装置に関する。 The present invention is a belt conveyor device capable of conveying medals, coins or heavy items even on a linear or curved conveyance path, and a medal is mainly used at a game island in a game store where a plurality of gaming machines and medal lending machines are connected in series. The present invention relates to a belt conveyor device used for conveying.

従来の遊技島においては、遊技機とメダル貸し機にメダルを供給するメダル供給ラインや、遊技機で使用されたメダルを回収するメダル回収ラインにベルトコンベヤ装置が用いられている。
ところで、ベルトコンベヤ装置の形状は直線状であり、遊技島の全体形状が湾曲している場合などでは、複数の短い直線的ベルトコンベヤ装置をその前後端同士で乗せ掛けて折れ線状に接続し、各装置間でメダルを乗り移らせながら搬送している（例えば特許文献１参照）。しかし、この方法はベルトコンベヤ装置が多数必要で（例えば２０台のスロットル台が設置された遊技島で約１０本）故障の発生が多くなり、乗せ掛けた箇所でメダルが詰まりやすくなる問題もあった。 In a conventional game island, a belt conveyor device is used for a medal supply line for supplying medals to a gaming machine and a medal lending machine and a medal collection line for collecting medals used in the gaming machine.
By the way, the shape of the belt conveyor device is linear, and when the entire shape of the game island is curved, a plurality of short linear belt conveyor devices are placed on the front and rear ends of the belt conveyor device and connected in a broken line shape. The medals are transferred while being transferred between the devices (for example, see Patent Document 1). However, this method requires a large number of belt conveyor devices (for example, about 10 on the amusement island with 20 throttle bases), and there is a problem that medals tend to clog at the place where they are placed. It was.

また、多数のモジュールを連結したモジュラーベルトを用いることで、メダルを曲線状に連続的に搬送できるようにした技術も提案されている（例えば特許文献２，３参照）。しかし、モジュラーベルトの構造が複雑で高価であり、装置も大型化して設置場所の制約を受けやすいものであった。 In addition, a technique has been proposed in which a medal can be continuously conveyed in a curved shape by using a modular belt in which a large number of modules are connected (see, for example, Patent Documents 2 and 3). However, the structure of the modular belt is complicated and expensive, and the apparatus is also large and is subject to restrictions on the installation location.

一方、ベルトコンベヤ装置のコンベヤフレームは、アルミニウム合金等の材料を直線状に押し出し成形した断面箱型の中空構造が一般的である（例えば特許文献３，４参照）。しかし、これらの技術では、曲線状の搬送ラインを実現するために長さの短い直線状のコンベヤフレームを折れ線状に複数連結しており、組み立てに手間を要していた。 On the other hand, a conveyor frame of a belt conveyor device generally has a cross-sectional box-shaped hollow structure in which a material such as an aluminum alloy is extruded and formed linearly (see, for example, Patent Documents 3 and 4). However, in these techniques, a plurality of linear conveyor frames having a short length are connected in a polygonal line in order to realize a curvilinear conveyance line, which requires time and effort for assembly.

本出願人は、一本の長尺の無端コンベヤベルトを使用してメダルを搬送する装置を開発した。一本の長尺の無端コンベヤベルトをメダル搬送に使用すると、多数個のメダルの重さが無端コンベヤベルトに垂直に荷重され、無端コンベヤベルトの送りにはベルトにスプリングによって適度な張力を与える必要となる。しかし、長期間使用すると無端コンベヤベルトが徐々に伸びて、ベルトとリターン部のプーリーとが滑って無端コンベヤベルトの送りができなくなる。それを解決すべく、長期間使用してベルトが伸びても張力が更に付勢できる構造の特殊な構造のベルト緊張装置を駆動プーリー側に設ける発明を開発した。その特許出願の公開公報が特許文献４である。これによって、前記問題点は解消した。更に、このベルト伸びに対する対応力を改良したのが引用文献５である。 The applicant has developed a device for transporting medals using a single long endless conveyor belt. When one long endless conveyor belt is used for conveying medals, the weight of a large number of medals is loaded perpendicular to the endless conveyor belt, and it is necessary to apply appropriate tension to the belt with a spring for feeding the endless conveyor belt. It becomes. However, when used for a long period of time, the endless conveyor belt is gradually extended, and the belt and the pulley of the return portion slip to make it impossible to feed the endless conveyor belt. In order to solve this problem, an invention has been developed in which a belt tensioning device having a special structure is provided on the drive pulley side so that tension can be further applied even when the belt is extended over a long period of time. The publication of the patent application is Patent Document 4. As a result, the above problems have been solved. Further, Patent Document 5 improves the response to the belt elongation.

これらの問題点を解消すべく、短ベルトの多数本連結した長尺の無端コンベヤベルトを本出願人は開発した。しかし、このベルトコンベヤを湾曲した搬送路で使用するとベルトとコンベヤの左右を拘束する側面板等との摩擦が増えて大きな抵抗が発生する。又、無端コンベヤベルトのリターンした復路側ベルト（下方側ベルト）が緩んで、このベルト部分に駆動力が伝わり難くなり、又駆動プーリー（駆動ローラ）部分でベルトの弛みが発生し、引用文献４，５の緊張装置では充分に対応できず、ベルトが駆動できなくなる場合が発生する。 In order to solve these problems, the present applicant has developed a long endless conveyor belt in which a plurality of short belts are connected. However, when this belt conveyor is used on a curved conveyance path, friction between the belt and the side plates restraining the left and right of the conveyor increases, and a large resistance is generated. Further, the return side belt (lower side belt) returned from the endless conveyor belt is loosened, and it becomes difficult to transmit the driving force to the belt portion, and the belt is loosened at the driving pulley (driving roller) portion. , 5 cannot sufficiently cope with the tension device, and the belt cannot be driven.

本発明によれば、短ベルトを多数連結した無端コンベヤベルトのリターン用ローラに対し、外方向に緊張装置で引張したことにより、無端コンベヤベルトは引張力が付与されてローラとよく密着して、無端コンベヤベルトとローラとが滑ることが少なくなる。その上で、往路始端側のローラの上のベルトは押え回転ローラが押圧することで、無端コンベヤベルトの各短ベルトはリターン用ローラと加圧力をもって挟まれることで大きな摩擦力が発生し、リターン用ローラの回転によって挟まれた短ベルトはベルト送り方向に強い推進力が与えられる。
従って、無端コンベヤベルトが途中で湾曲して、ベルト引張力が短ベルトを湾曲中心（曲率中心）方向に作用して側壁体と強く接触して高い摩擦抵抗が発生しても、上記推進力が直進する力となって湾曲部の短ベルトを湾曲中心と反対方向の力として作用して、ベルトと湾曲した側壁体との強い接触を緩らげて、摩擦抵抗を少なくして湾曲した搬送路でも円滑に送ることができるようになる。 According to the present invention, the return roller of the endless conveyor belt in which a number of short belts are connected is pulled outward by a tensioning device, whereby the endless conveyor belt is given a tensile force and is in close contact with the roller, Less slippage between the endless conveyor belt and the rollers. In addition, the belt above the roller on the start side of the forward path is pressed by the pressing rotation roller, and each short belt of the endless conveyor belt is sandwiched between the return roller and the applied pressure, and a large frictional force is generated. The short belt sandwiched by the rotation of the roller for application is given a strong driving force in the belt feeding direction.
Therefore, even if the endless conveyor belt is bent in the middle and the belt tension acts on the short belt in the direction of the center of curvature (center of curvature) and comes into strong contact with the side wall body, the above-mentioned propulsive force is generated. A straight conveying force that acts as a force in the direction opposite to the bending center of the short belt of the curved portion, loosening the strong contact between the belt and the curved side wall, reducing the frictional resistance, and the curved conveying path But it will be able to send smoothly.

更に、前後のリターン用ローラの両方とも駆動装置で強制駆動されれば、復路のベルトもローラで強制送りがなされ、緩みが更に確実に解消される。 Further, if both the front and rear return rollers are forcibly driven by the drive unit, the belt in the return path is also forcibly fed by the rollers, and the looseness is more reliably eliminated.

又、ローラの外周部の表面にローレット又は高い摩擦面にすれば滑りをなくし、確実にローラで無端コンベヤベルトを強制送り可能とする。これは、駆動部のないリターン側ローラでも採用でき、無端コンベヤベルトとの滑りもなく確実に送れるようにする。 Further, if the surface of the outer peripheral portion of the roller is knurled or has a high friction surface, slipping is eliminated, and the endless conveyor belt can be forcibly fed by the roller reliably. This can also be adopted with a return side roller without a drive part, and ensures that it can be fed without slipping with the endless conveyor belt.

更に、ベルト受面フレームの上面に送り方向の溝を複数本設ける構造とすれば、連結具又は中間連結具の下方突出部を溝内に収容して下方突出部がベルト受面フレームの上面と接触することがなくなり、送りにベルト受面フレームとの接触抵抗がなくなり、ベルト引張力が小さくできる。又、ベルト受面フレームに傷つけることもない。 Further, if a structure is provided in which a plurality of grooves in the feed direction are provided on the upper surface of the belt receiving surface frame, the lower protruding portion of the connecting tool or intermediate connecting tool is accommodated in the groove, and the lower protruding portion is connected to the upper surface of the belt receiving surface frame. There is no contact, there is no contact resistance with the belt receiving frame for feeding, and the belt tension can be reduced. Further, the belt receiving surface frame is not damaged.

更に、短ベルトの前後端の中間で巾中央位置に中間連結具を設ければ、短ベルトの送り方向の長さの中間位置でもローラと係止することができ、前後端の連結具と中間連結具の下方突出部によるローラとの係止のベルト長さに対する回数が増え、より確実に無端コンベヤベルトを滑りが少なく送れるようになる。 Furthermore, if an intermediate connector is provided in the middle of the width between the front and rear ends of the short belt, it can be locked to the roller even at the intermediate position of the length of the short belt in the feed direction. The number of times of locking with the roller by the downward projecting portion of the coupler increases with respect to the belt length, and the endless conveyor belt can be more reliably fed with less slippage.

本願発明の短ベルトは送り方向には弾性変形できるが幅方向に変形しにくい短ベルトであり、リターン部のローラのローラ外周面の曲率に沿って変形できて、復路又は往路になって送れる程度の柔らかさがあるものであって、又コンベヤフレームの側壁体との接触で短ベルトの左右部分が大きく上向き又は下向きに湾曲変形しないで、湾曲部を曲れる程のある程度の剛性・硬さを有することを意味する。 The short belt of the present invention is a short belt that can be elastically deformed in the feed direction but is difficult to deform in the width direction, and can be deformed along the curvature of the roller outer peripheral surface of the roller of the return portion, and can be fed in the return path or the forward path In addition, the right and left parts of the short belt are not greatly deformed upward or downward due to contact with the side wall of the conveyor frame, and have a certain degree of rigidity and hardness enough to bend the curved part. It means having.

本発明のコンベヤフレームの垂直の側壁体は、無端コンベヤベルトの往路・復路においてベルトと接触してベルトの左右の動きを規制して、湾曲した無端コンベヤベルトでも曲線的に送れるようにする。 The vertical side wall body of the conveyor frame of the present invention is in contact with the belt in the forward / return path of the endless conveyor belt to restrict the left and right movement of the belt so that even a curved endless conveyor belt can be fed in a curved line.

無端コンベヤベルトの短ベルトの長さ・巾・厚みは、コンベヤ搬送路の湾曲の曲率、搬送する物品の長さに応じて適切な寸法が採用される。
又、短ベルトの連結具としてはリベット・ボルトナット・ハトメ等が使用できる。又、短ベルトは高い引張力に耐え、搬送物品の重量に耐え、又摩擦に強い素材が選択される。帆布を複数枚積層したものが短ベルトに適する。
特に、リベットを連結具とし、しかも下方をワッシャを介してかしめるようにすれば、リベットと短ベルトの摩擦が少なくなり、短ベルトの水平折れ曲がりの回転運動が円滑にでき、湾曲した搬送路でのベルト送りが容易となる。
又、ステンレス製のボルト・ワッシャ・ナットに比べ、アルミ製のリベットとワッシャの方がボルト回転操作が不要な分打撃を与えるだけで連結できるので、部品コスト及び連結作業費も安価にできる。
しかも、短ベルトを連結する無端コンベヤベルトの長さの調整も短ベルト長さの単位で短縮したり、又は延長することが容易となる。又、一部のベルト部分の損傷があってもその損傷した部分の短ベルトを交換するので、部分損傷が解消でき易くする利点がある。 The length, width, and thickness of the short belt of the endless conveyor belt are appropriately determined according to the curvature of the conveyor conveyance path and the length of the article to be conveyed.
Also, rivets, bolt nuts, eyelets, etc. can be used as a short belt connector. In addition, the short belt can withstand a high tensile force, can withstand the weight of the conveyed article, and can be selected from a material that is resistant to friction. A laminate of multiple canvases is suitable for short belts.
In particular, if a rivet is used as a connecting tool and the lower part is caulked through a washer, the friction between the rivet and the short belt is reduced, and the horizontal belt can be smoothly bent and rotated in a curved conveyance path. The belt can be fed easily.
In addition, compared to stainless steel bolts, washers and nuts, aluminum rivets and washers can be connected only by hitting them without the need to rotate the bolts, so the parts cost and connection work cost can be reduced.
In addition, adjustment of the length of the endless conveyor belt connecting the short belts can be easily shortened or extended in units of the short belt length. In addition, even if a part of the belt is damaged, the short belt of the damaged part is replaced, so that there is an advantage that the partial damage can be easily solved.

無端コンベヤベルト３の往路始端側のローラ４ｃの上端に接触した短ベルト３ａは、上方から押え回転ローラ６がスプリング６ｃに下方向の付勢力をもって加圧している。しかも、ローラ４ｃの外周段部４ｅとの外周表面はローレットを与えて高い摩擦面となっているため、押え回転ローラ６と下方のローラ４ｃとに挟まれている短ベルト３ａに加圧力による強い摩擦力がローラ４ｃに発生させ、短ベルト３ａにベルト送り方向に高い推進力が与えられる。押え回転ローラ６は加圧力は与えるが、ベルトの送りを抑える抵抗はベアリング６ｇで回転自在であることで小さく、この加圧力とローラ４ｃの高い摩擦力によってローラ４ｃの送り方向に直進的な強い推進力が短ベルト３ａに発生する。無端コンベヤベルト３が湾曲した搬送路において、上記推進力は図４に示すように湾曲曲率中心と反対方向の力として作用し、無端コンベヤベルト３のコンベヤフレーム４の側壁体４ｂとの接触を弱め、湾曲した搬送路でも側壁体４ｂとの接触抵抗を少なく円滑に搬送できるようになる。 The short belt 3a that has contacted the upper end of the roller 4c on the forward path start end side of the endless conveyor belt 3 is pressed from above by the pressing rotary roller 6 against the spring 6c with a downward biasing force. Moreover, since the outer peripheral surface of the roller 4c with the outer peripheral step portion 4e is a high friction surface by imparting knurls, the short belt 3a sandwiched between the presser rotating roller 6 and the lower roller 4c is strong due to the applied pressure. A frictional force is generated on the roller 4c, and a high driving force is applied to the short belt 3a in the belt feeding direction. The presser rotating roller 6 gives pressure, but the resistance to restrain the belt feed is small because it can be rotated by the bearing 6g, and is small because the pressure and the high frictional force of the roller 4c make it straight and strong in the feed direction of the roller 4c. Propulsive force is generated in the short belt 3a. In the conveyance path in which the endless conveyor belt 3 is curved, the propulsive force acts as a force in the direction opposite to the center of curvature as shown in FIG. 4, and weakens the contact between the endless conveyor belt 3 and the side wall 4b of the conveyor frame 4. Even in the curved conveyance path, the contact resistance with the side wall body 4b can be smoothly conveyed.

図１１〜１７に示す実施例２は、往路終端側のリターン用ローラ４ｃにも駆動装置５を取付けている。この駆動装置５は緊張装置８の軸受フレーム８ａに取付けられ、そして、ローラ４ｃのローラ軸４ｃ_２に取付けられたスプロケット４ｃ_３と駆動装置５の出力軸に取付けたスプロケット５ａとの間にチェーン５ｂで伝動している。軸受フレーム８ａが進退しても駆動装置５とローラ軸４ｃ_２も同じように動くので、進退してもローラ４ｃを緊張装置８で引張しながら回動力は伝動できるようになっている。
この実施例２は始端及び終端のローラ４ｃとともに強制駆動されるので、無端コンベヤベルト３はローラ４ｃと滑りなく、又ベルト緩みなく周回できる。よって、無端コンベヤベルト３が湾曲しても、更に確実に搬送できるようになる。
他の構造・作用効果は実施例１と同様である。 In the second embodiment shown in FIGS. 11 to 17, the driving device 5 is also attached to the return roller 4 c on the forward path end side. The driving device 5 is attached to the bearing frame 8a of the tensioning device 8 and the chain 5b between the sprocket 5a mounted on the output shaft of the sprocket 4c ₃ and the drive device 5 mounted on the roller shaft 4c ₂ of the roller 4c It is transmitted in. Since even the bearing frame 8a moves back and forth movement as same driving device 5 and the roller shaft 4c _2, tensile while rotating force by tensioning device 8 the roller 4c be retractable is adapted to be transmission.
Since the second embodiment is forcibly driven together with the start and end rollers 4c, the endless conveyor belt 3 can rotate around the rollers 4c without slipping or loosening the belt. Therefore, even if the endless conveyor belt 3 is curved, it can be transported more reliably.
Other structures and operational effects are the same as those of the first embodiment.
