Description

本発明は、無端索条体に設けた複数の仕切り部材の間に物品を受け入れて搬送する物品搬送装置に関する。   The present invention relates to an article transporting apparatus that receives and transports articles between a plurality of partition members provided on an endless cable body.

この種の物品搬送装置として、例えば、特許文献１は、物品の前後を区画する仕切り部材を備えた物品保持部材を備え、物品保持部材がコンベヤの下方から上方へ旋回する途中で、仕切り部材の前後に順次物品を受け入れて排出位置まで搬送し、包装機などの処理機に向けて供給するために、前記排出位置において複数個ずつの物品を一括して排出する物品搬送装置において、仕切り部材に受け入れた物品を排出位置に向けて搬送する際に仕切り部材から物品が飛び出すのを防止することを目的としている。   As this type of article conveying device, for example, Patent Document 1 includes an article holding member including a partition member that partitions the front and rear of an article, and the article holding member is turned on the way from the lower side of the conveyor to the upper side. In order to receive articles sequentially before and after, convey them to a discharge position, and supply them to a processing machine such as a packaging machine, in the article transfer apparatus that discharges a plurality of articles at a time at the discharge position, The object is to prevent the article from jumping out of the partition member when the received article is conveyed toward the discharge position.

この引用文献1に開示の物品搬送装置では、物品保持部材が受け入れ位置で各仕切り部材間の保持空間に搬入コンベヤから物品を受け入れる期間中は、各仕切り部材が下方から上方へ旋回する途中のほぼ水平状態になったときに、各仕切り部材の間に搬入コンベヤからの物品を受け入れ、所定数の物品の最後の物品が保持空間に搬入されたときに、ほぼ水平状態で物品を受け入れた仕切り部材が斜め上向きの姿勢になるまで低速移動して一旦停止した後に、所定の搬送速度で下流側に移動するように、搬送手段を駆動している。
このように、ほぼ水平状態で最後の物品を受け入れた仕切り部材が、所定の傾斜姿勢になった後に、物品保持部材は物品の受け入れ期間中の速度より、高速で移動させることで、高速搬送時においても、搬送装置の旋回時に物品に作用する遠心力に対抗する物品に作用する重力の反遠心力方向の成分によって、物品保持部材からの物品の飛び出しを防止できるようにしている。 In the article conveying apparatus disclosed in the cited document 1, during the period in which the article holding member receives the article from the carry-in conveyor in the holding space between the partition members at the receiving position, each partition member is almost in the middle of turning from below to above. A partition member that receives an article from the carry-in conveyor between the partition members when it is in a horizontal state, and receives the article in a substantially horizontal state when the last article of a predetermined number of articles is carried into the holding space. The conveying means is driven so as to move to a downstream side at a predetermined conveying speed after moving at a low speed until it becomes an obliquely upward posture and once stopped.
As described above, after the partition member that has received the last article in a substantially horizontal state is in a predetermined inclined posture, the article holding member is moved at a higher speed than the speed during the article receiving period. In this case, the jumping-out of the article from the article holding member can be prevented by the component in the anti-centrifugal force direction of the gravity acting on the article that opposes the centrifugal force acting on the article when the conveying device turns.

しかしながら、搬送手段の搬送速度が、例えば、５００個／分以上の極めて高速での搬送処理を要求する場合において、物品が搬送手段の各仕切り部材間に搬入された際に、物品が仕切り部材間の物品支持底部に衝突して、搬入方向に跳ね返って、各仕切り部材間に受け入れた物品が、受入れ空間から飛び出し、排出位置まで良好に搬送し得ないという問題があった。このような問題点に対する有効な解決策は、従来、提案されていない。   However, when the conveying speed of the conveying means requires, for example, a conveying process at an extremely high speed of 500 pieces / minute or more, when the article is carried between the partition members of the conveying means, the article is between the partition members. There was a problem that the article that hit the bottom of the article support, bounced back in the loading direction, and received between the partition members jumped out of the receiving space and could not be conveyed well to the discharge position. Conventionally, no effective solution to such a problem has been proposed.

そこで本発明は、前記従来技術に内在した問題に鑑み、コンベヤにおける各仕切り部材の間に搬入された物品が跳ね返って収容区画外に飛び出してしまうことがなく、物品を各仕切り部材の間に確実に収容して搬送し得る物品搬送装置を提供することを目的とする。   Therefore, in view of the problems inherent in the prior art, the present invention ensures that the articles carried between the partition members in the conveyor do not bounce off and jump out of the storage compartment, so that the articles can be reliably placed between the partition members. It is an object of the present invention to provide an article conveying apparatus that can be accommodated and conveyed.

請求項１に記載の発明に係る物品搬送装置によれば、上下方向に巻き掛け案内される無端索条体１０の走行方向に向けて所定間隔ごとに配設した各仕切り部材１１を間欠的に前進移動し、受入位置Ｐ１で各仕切り部材１１間の収容区画に順次受け入れた物品Ｗを、排出位置Ｐ２まで移動して各収容区画から取り出す搬送コンベヤ１を設け、仕切り部材１１は、その先端部において搬送方向前方に向けて張り出す第１案内部１１ｂを備え、収容区画へ搬入された物品Ｗの前端が、該収容区画の底部１６に到るまでに仕切り部材１１を前進移動して第１案内部１１ｂで物品Ｗの重心Ｗｐより後方を無端索条体１０の走行方向前方へ向けて押して物品Ｗの前方を仕切り部材１１の移動方向後方に向けて傾動させるようにした。   According to the article conveying apparatus according to the first aspect of the present invention, the partition members 11 disposed at predetermined intervals are intermittently disposed in the traveling direction of the endless rope body 10 that is wound and guided in the vertical direction. A transport conveyor 1 that moves forward and sequentially receives articles W that are received in the storage compartments between the partition members 11 at the receiving position P1 to the discharge position P2 and takes out from the storage compartments is provided. The first guide portion 11b that protrudes forward in the transport direction is provided, and the partition member 11 is moved forward until the front end of the article W carried into the storage section reaches the bottom 16 of the storage section. The rear of the article W from the center of gravity Wp of the article W is pushed toward the front of the endless ridge 10 in the traveling direction by the guide portion 11b to tilt the front of the article W toward the rear of the partition member 11 in the moving direction.

このように、物品Ｗの前端が、該収容区画の底部１６に到る前に、仕切り部材１１を前進して物品Ｗの重心Ｗｐより後方を押して物品Ｗの前方を傾動させるので、収容区画へ搬入される物品Ｗの搬入方向に向けて前進する運動エネルギーが吸収され、物品前端が収容区画の底部１６に衝突して跳ね返って収容区画から飛び出してしまうようなことがなく、確実な物品搬送を行うことができる。   In this way, before the front end of the article W reaches the bottom 16 of the accommodation section, the partition member 11 is advanced and the rear side of the center of gravity Wp of the article W is pushed to tilt the front of the article W. The kinetic energy that moves forward in the loading direction of the article W to be carried in is absorbed, and the front end of the article does not collide with the bottom 16 of the accommodation section and bounce off and jump out of the accommodation section, so that the article can be conveyed reliably. It can be carried out.

また、請求項２に記載の発明に係る物品搬送装置によれば、収容区画へ向けた物品Ｗの受入位置Ｐ１の上流側に近接する位置に、物品Ｗを検知するセンサＳを設け、該センサＳの検出結果によって、物品Ｗが収容区画の底部１６に到るまでに前記無端索条体１０の移動を行うようにした。これにより、物品Ｗの収容区画への正確な送り込み時期を判断できる。   In addition, according to the article transporting apparatus according to the second aspect of the present invention, the sensor S that detects the article W is provided at a position close to the upstream side of the receiving position P1 of the article W toward the accommodation section, and the sensor According to the detection result of S, the endless cord 10 is moved before the article W reaches the bottom 16 of the storage compartment. Thereby, it is possible to determine the exact time of sending the article W to the accommodation section.

また、請求項３に記載の発明に係る物品搬送装置によれば、搬送コンベヤ１における物品Ｗの受入位置Ｐ１は、無端索条体１０の上流側転向部Ｌ２に設定され、受入位置Ｐ１に物品Ｗを所定間隔毎に搬入する供給コンベヤ２０を接続するとともに、供給コンベヤ２０の走行量を検出する検出手段を設け、該検出手段と前記センサＳとから得られる物品Ｗの収容区画への送り込みタイミングに応じて仕切り部材１１を前進移動するよう無端索条体１０を間欠走行するようにした。このため、物品Ｗが収容区画へ送り込まれる時期を精度よく把握することができ、仕切り部材１１の移動時期を正確に動作させることができる。   Further, according to the article conveying apparatus according to the third aspect of the present invention, the receiving position P1 of the article W on the conveying conveyor 1 is set at the upstream turning portion L2 of the endless strip 10, and the article is placed at the receiving position P1. The supply conveyor 20 that carries W at predetermined intervals is connected, and detection means for detecting the travel amount of the supply conveyor 20 is provided, and the feed timing of the article W obtained from the detection means and the sensor S to the accommodation section Accordingly, the endless cord body 10 is intermittently traveled so as to move the partition member 11 forward. For this reason, it is possible to accurately grasp the time when the article W is sent into the storage compartment, and the movement time of the partition member 11 can be accurately operated.

また、請求項４に記載の発明に係る物品搬送装置によれば、前記仕切り部材１１は、板状材が折り曲げ形成され、基部１１ａ側から無端索条体１０の走行方向と交差して延出する第３案内部１１ｄと、該第３案内部１１ｄの終端から搬送方向前方に向けて傾斜する第２案内部１１ｃと、先端部に形成され、第２案内部１１ｃの終端に接続して第３案内部１１ｄと平行に延在する第１案内部１１ｂとを備えている。このため、この仕切り部材１１は、アルミニウム、ステンレスその他の各種金属材料を折り曲げ加工処理などによって簡便に形成でき、また、安価なコストで製作できる。   Moreover, according to the article transporting apparatus according to the invention described in claim 4, the partition member 11 is formed by bending a plate-like material and extends from the base portion 11 a side so as to intersect with the traveling direction of the endless cord body 10. The third guide portion 11d, the second guide portion 11c inclined from the end of the third guide portion 11d toward the front in the transport direction, and formed at the tip portion, and connected to the end of the second guide portion 11c. 3 guide part 11d and the 1st guide part 11b extended in parallel are provided. For this reason, the partition member 11 can be easily formed by bending a metal material such as aluminum, stainless steel or the like, and can be manufactured at a low cost.

また、請求項５に記載の発明に係る物品搬送装置によれば、無端索条体１０は、第１の仕切り部材群１１０を有する第１の索条体１００と、第２の仕切り部材群１１１を有する第２の索条体１０１とを物品搬送路の左右へ並列に設けて、第１の索条体１００と第２の索条体１０１を、それぞれ個別の駆動手段１４、１４によって独立して走行するように構成し、前記第１の仕切り部材群１１０と、前記第２の仕切り部材群１１１とを、前記物品搬送路における搬送方向の前後に位置し、前記第１の仕切り部材群１１０が、前記受入位置Ｐ１で間欠移動して各物品Ｗを前記各収容区画に順次受け入れた後、前記排出位置Ｐ２まで移動するように第１の索条体１００を連続走行する一方、前記第２の仕切り部材群１１１が続いて前記受入位置Ｐ１において物品Ｗを順次受け入れて間欠移動するように第２の索条体１０１を間欠走行するので、単位時間当たりの物品Ｗの搬送処理量が増大し、生産性を高めることができる。   Further, according to the article transporting apparatus according to the invention described in claim 5, the endless cable body 10 includes the first cable body 100 having the first partition member group 110 and the second partition member group 111. Are provided in parallel to the left and right of the article conveyance path, and the first and second strips 100 and 101 are made independent by individual driving means 14 and 14, respectively. The first partition member group 110 and the second partition member group 111 are positioned before and after in the transport direction in the article transport path, and the first partition member group 110 However, after intermittently moving at the receiving position P1 and sequentially receiving the articles W into the receiving compartments, the first ridge body 100 continuously travels to move to the discharge position P2, while the second The partition member group 111 continues to the receiving position P1. Since intermittently travels a second rope member 101 so as to intermittently move sequentially accept Oite article W, conveying throughput of the article W per unit time is increased, the productivity can be enhanced.

本発明によれば、物品に反遠心力方向の成分が発生するので、物品の仕切り部材間からの飛び出しを防止できる。   According to the present invention, since a component in the anti-centrifugal force direction is generated in the article, it is possible to prevent the article from jumping out between the partition members.

（実施例）
本発明の物品搬送装置における好適な実施形態について、先ず、搬送コンベヤ１の基本的構成について概説する。なお、搬送コンベヤ１は、直線走行部と転向部とを含む搬送経路を形成する無端索条体１０と、該無端策条体１０に並設されて搬送経路上を走行する複数の仕切り部材１１とを有するものであって、これら基本的構成は下記で説明する実施形態に限定されず、公知の装置を広く採用することができる。 (Example)
Regarding a preferred embodiment of the article conveying device of the present invention, first, the basic configuration of the conveying conveyor 1 will be outlined. In addition, the conveyance conveyor 1 is the endless rope body 10 which forms the conveyance path | route including a linear running part and a turning part, and the some partition member 11 which is parallelly arranged in this endless measure body 10, and travels on a conveyance path | route. These basic configurations are not limited to the embodiments described below, and a wide range of known devices can be employed.

図１〜図３に示すように、搬送コンベヤ１は、直線走行部Ｌ１と転向部Ｌ２とを含む搬送経路に上下方向に巻き掛けられた無端索条体としての歯付ベルト１０と、当該歯付ベルト１０の搬送方向に沿って設けられ搬送経路上を走行する複数の仕切り部材１１とを有する。歯付ベルト１０は、上流側に配された駆動歯付プーリ１２と下流側に配された従動歯付プーリ１３との間に巻き掛けられている。歯付ベルト１０が各歯付プーリ１２、１３に巻き掛けられる部分が転向部Ｌ２となり、上下流の転向部Ｌ２、Ｌ２の間が上下流の直線走行部Ｌ１、Ｌ１となる。駆動歯付プーリ１２は、機枠の側壁１５の外側に配設したサーボモータ１４によって、下方から上方に向けて時計方向に回転駆動される。後述の受入位置Ｐ１から排出位置Ｐ２にかけて物品Ｗの載置面を漸次増高する案内レール１６が、搬送経路に沿って設けられている。また、歯付ベルト１０には、仕切り部材１１が所定の間隔で着脱可能に固着されている。   As shown in FIG. 1 to FIG. 3, the conveyor 1 includes a toothed belt 10 as an endless strip wound around a transport path including a straight traveling portion L1 and a turning portion L2, and the tooth A plurality of partition members 11 provided along the conveying direction of the attached belt 10 and traveling on the conveying path. The toothed belt 10 is wound around a driving toothed pulley 12 arranged on the upstream side and a driven toothed pulley 13 arranged on the downstream side. A portion where the toothed belt 10 is wound around each of the toothed pulleys 12 and 13 is a turning portion L2, and a portion between the upstream and downstream turning portions L2 and L2 is an upstream and downstream straight traveling portion L1 and L1. The drive toothed pulley 12 is rotationally driven in a clockwise direction from below to above by a servo motor 14 disposed outside the side wall 15 of the machine frame. A guide rail 16 is provided along the conveyance path for gradually increasing the placement surface of the article W from a receiving position P1 (described later) to a discharging position P2. A partition member 11 is detachably fixed to the toothed belt 10 at a predetermined interval.

搬送コンベヤ１には、これに接続された無端ベルトなどからなる供給コンベヤ２０によって、煎餅やビスケット、その他の薄肉厚の物品Ｗが順次供給されてくる。供給コンベヤ２０の先端は搬送コンベヤ１における上流側の転向部Ｌ２に臨んでおり、当該転向部Ｌ２にある受入位置Ｐ１において、物品Ｗが各仕切り部材１１で画成される収容区画に順次受け入れられる。尚、供給コンベヤ２０の下流側には、前記受入位置Ｐ１に向けて搬送される物品Ｗの通過を検出する光電センサなどのセンサＳが配設されている。   The conveyor 1 is sequentially supplied with rice crackers, biscuits and other thin-walled articles W by a supply conveyor 20 comprising an endless belt connected to the conveyor 1. The leading end of the supply conveyor 20 faces the upstream turning portion L2 of the transfer conveyor 1, and the articles W are sequentially received in the receiving sections defined by the partition members 11 at the receiving position P1 in the turning portion L2. . A sensor S such as a photoelectric sensor for detecting the passage of the article W conveyed toward the receiving position P1 is disposed on the downstream side of the supply conveyor 20.

また、供給コンベヤ２０には、該供給コンベヤ２０の走行量を検出するエンコーダ等からなる検出手段が設けられており、前記センサＳの物品Ｗの通過後に検出手段から得たコンベヤの走行量に基づき、受入位置Ｐ１においては、１個の物品Ｗが１つの収容区画に順次送り込まれるタイミングで歯付ベルト１０を停止するよう間欠走行する。仕切り部材群の全ての収容区画のそれぞれに物品Ｗが受け入れられると、各物品Ｗの前後が各仕切り部材１１によって支持され、転向部Ｌ２を経た直線走行部Ｌ１の排出位置Ｐ２まで連続走行する。各物品Ｗは、転向部Ｌ２を越えた直線走行部Ｌ１において案内レール１６によって徐々に各仕切り部材１１の上方へ突出するように持ち上げられる。そして、直線走行部Ｌ１の終端部にある排出位置Ｐ２へ到達すると、図示していない排出プッシャによって、仕切り部材群の全ての物品Ｗを一括して直線走行部Ｌ１の一側方へ押し出す。全ての物品Ｗが排出されると、歯付ベルト１０及び仕切り部材１１は、再度高速で受入位置Ｐ１まで連続走行する。このように、歯付ベルト１０が間欠走行することで、所定個数の物品の受け入れ、搬送、排出が繰り返される。   Further, the supply conveyor 20 is provided with detection means including an encoder for detecting the travel amount of the supply conveyor 20, and based on the travel amount of the conveyor obtained from the detection means after passing the article W of the sensor S. In the receiving position P1, intermittent running is performed so that the toothed belt 10 is stopped at a timing when one article W is sequentially fed into one receiving section. When the articles W are received in all of the storage compartments of the partition member group, the front and rear of each article W are supported by the partition members 11 and continuously travel to the discharge position P2 of the linear travel section L1 through the turning section L2. Each article W is lifted up so as to gradually protrude above each partition member 11 by the guide rail 16 in the straight traveling portion L1 beyond the turning portion L2. Then, when reaching the discharge position P2 at the terminal end of the straight traveling portion L1, all articles W in the partition member group are pushed out to one side of the straight traveling portion L1 by a discharge pusher (not shown). When all the articles W are discharged, the toothed belt 10 and the partition member 11 continuously travel to the receiving position P1 again at a high speed. As described above, the toothed belt 10 intermittently travels so that a predetermined number of articles are repeatedly received, conveyed, and discharged.

歯付ベルト１０は、搬送経路の左右に第１の歯付ベルト（第１の索条体）１００と第２の歯付ベルト（第２の索条体）１０１が並行に設けられており、各歯付ベルト１００、１０１が巻き掛けられた駆動歯付プーリ１２、１２の各々に、個別で連結されたサーボモータ１４で、各歯付ベルト１００、１０１が独立して走行するよう駆動制御される。そして、第１の歯付ベルト１００と第２の歯付ベルト１０１の双方に、それぞれ同数の仕切り部材１１が設けられている。そのうえで、第１の歯付ベルト１００に設けられた第１の仕切り部材群１１０と、第２の歯付ベルト１０１に設けられた第２の仕切り部材群１１１とは、搬送経路を共有しながら搬送方向に前後して位置している。   The toothed belt 10 includes a first toothed belt (first strip) 100 and a second toothed belt (second strip) 101 provided in parallel on the left and right of the transport path. Each toothed belt 100, 101 is driven and controlled by a servo motor 14 individually connected to each of the drive toothed pulleys 12, 12 around which each toothed belt 100, 101 is wound. The The same number of partition members 11 are provided on both the first toothed belt 100 and the second toothed belt 101. In addition, the first partition member group 110 provided on the first toothed belt 100 and the second partition member group 111 provided on the second toothed belt 101 are transported while sharing a transport path. Located back and forth in the direction.

前述の如く第１の仕切り部材群１１０が受入位置Ｐ１で物品Ｗを順次受け入れて排出位置Ｐ２まで移動するように第１の歯付ベルト１００を連続走行する一方、第２の仕切り部材群１１１が続いて第１の仕切り部材群１１０と同様にして前記受け入れ位置Ｐ１において物品を順次受け入れて間欠移動するように第２の歯付ベルト１０１を間欠走行する。このように、第１の仕切り部材群１１０と第２の仕切り部材群１１１で交互に受け入れ、搬送、排出が行われることで、単位時間あたりの搬送処理量が増大される。   As described above, the first toothed belt 100 continuously travels so that the first partition member group 110 sequentially receives the articles W at the receiving position P1 and moves to the discharge position P2, while the second partition member group 111 includes the second partition member group 111. Subsequently, similarly to the first partition member group 110, the second toothed belt 101 is intermittently traveled so that articles are sequentially received and intermittently moved at the receiving position P1. In this manner, the first partition member group 110 and the second partition member group 111 alternately receive, transport, and discharge, thereby increasing the transport processing amount per unit time.

次に、前記仕切り部材１１について図４（ｂ）を参照して説明する。仕切り部材１１は、アルミニウム、ステンレス等の金属材料の平板が折り曲げ形成され、基部１１ａ、第１案内部１１ｂ、第２案内部１１ｃ、第３案内部１１ｄとで構成されている。
基部１１ａが、前記歯付ベルト１０における各山型歯部１０ａの上部に形成された基台１０ｂの上面に載置されてネジ止めされ、前記第２案内部１１ｃが基部１１ａから歯付ベルト１０の走行方向と交差する方向に延びるよう形成され、また、前記第１案内部１１ｂは、仕切り部材１１の先端部において、第２案内部１１ｃの延出位置より歯付ベルト１０の搬送方向前方（歯付ベルト１０の走行方向前方に向けて張り出した位置）に形成され、第２案内部１１ｃと平行に所定長さに亘り延在している。また、前記第３案内部１１ｄは、第２案内部１１ｃの終端から搬送方向前方に向けて傾斜し、第１案内部１１ｂの一端部に接続するよう構成されている。 Next, the partition member 11 will be described with reference to FIG. The partition member 11 is formed by bending a flat plate of a metal material such as aluminum or stainless steel, and includes a base portion 11a, a first guide portion 11b, a second guide portion 11c, and a third guide portion 11d.
The base 11a is placed on the upper surface of a base 10b formed on the top of each chevron tooth portion 10a of the toothed belt 10 and screwed, and the second guide portion 11c is connected to the toothed belt 10 from the base 11a. The first guide portion 11b is formed at the front end of the partition member 11 at the front end in the conveying direction of the toothed belt 10 from the extended position of the second guide portion 11c (see FIG. The toothed belt 10 is formed at a position projecting forward in the traveling direction) and extends in parallel with the second guide portion 11c over a predetermined length. Further, the third guide portion 11d is configured to incline toward the front in the transport direction from the end of the second guide portion 11c and to be connected to one end portion of the first guide portion 11b.

前記仕切り部材１１は、図３に示すように、左右の歯付ベルト１００、１０１へ、前記各案内部１１ｂ、１１ｃ、１１ｄが搬送経路の搬送ライン中心に合致するように基部１１ａから一側方に突出した状態で位置決めされて固着される。これにより、左右の歯付ベルト１００、１０１に設けられた第１、第２の仕切り部材群１１０、１１１が、１つの搬送経路を走行するよう位置付けることができる。   As shown in FIG. 3, the partition member 11 extends from the base 11 a to the left and right toothed belts 100, 101 so that the guide portions 11 b, 11 c, 11 d coincide with the center of the transport line of the transport path. It is positioned and fixed in a protruding state. Thereby, the 1st, 2nd partition member groups 110, 111 provided in the left and right toothed belts 100, 101 can be positioned so as to travel along one transport path.

このような仕切り部材１１を設けた搬送コンベヤ１を備えた物品搬送装置において、図４（ａ）に示したように、供給コンベヤ２０で搬送される物品Ｗは、センサＳで検出されて、搬送コンベヤ１における各仕切り部材１１で画成される収容区画に順次搬入される。搬送コンベヤ１はサーボモータ１４の駆動によって物品Ｗが所定間隔毎に搬送されてくる度に前記収容区画を順送りするように間欠走行するとともに、前記センサＳと供給コンベヤ２０の走行量を検出する検出手段とから得られる前記収容区画への物品Ｗの搬入タイミングに合わせて以下のように動作するよう走行駆動される。   In the article conveying apparatus including the conveying conveyor 1 provided with such a partition member 11, as shown in FIG. 4A, the article W conveyed by the supply conveyor 20 is detected by the sensor S and conveyed. The conveyor 1 is sequentially loaded into a storage compartment defined by the partition members 11. The transport conveyor 1 intermittently travels so as to sequentially feed the storage section every time the article W is transported at predetermined intervals by the drive of the servo motor 14 and detects the travel amount of the sensor S and the supply conveyor 20. The vehicle is driven to operate as follows in accordance with the timing of carrying the article W into the storage compartment obtained from the means.

すなわち、搬送コンベヤ１における仕切り部材１１が下方から上方に向かう転向部Ｌ２において、前記供給コンベヤ２０によって水平搬送されて、受入位置Ｐ1に到来した物品Ｗは、搬送方向前方が下方へ傾斜した姿勢となるように前記収容区画へ送り込まれる。そのとき、物品Ｗの下方に臨む仕切り部材１１における第１案内部１１ｂが物品の下面を支持して案内する。
前記収容区画に搬入された物品Ｗの重心Ｗｐが、前記第１案内部１１ｂを越えて基部１１ａ側に寄った位置まで送り込まれ、物品Ｗの先端が収容区画の底部となる前記案内レール１６に当接する前に、前記サーボモータ１４の駆動によって搬送コンベヤ１が走行されて、仕切り部材１１は搬送方向へ前進移動すべく転向部から上方に向けて移動する。 That is, the article W which is horizontally conveyed by the supply conveyor 20 and arrives at the receiving position P1 in the turning portion L2 in which the partition member 11 of the conveyor 1 is directed upward from below has a posture in which the front in the conveyance direction is inclined downward. It is sent to the storage compartment. At that time, the first guide portion 11b of the partition member 11 facing the lower side of the article W supports and guides the lower surface of the article.
The center of gravity Wp of the article W carried into the accommodation section is sent to a position near the base portion 11a beyond the first guide portion 11b, and the tip of the article W becomes the bottom of the accommodation section. Before the contact, the conveyor 1 is driven by the drive of the servo motor 14, and the partition member 11 moves upward from the turning portion so as to move forward in the conveying direction.

この仕切り部材１１の前進移動によって、物品Ｗの重心Ｗｐより送り込み後方側は前記第３案内部１１ｄによって搬送コンベヤ１の搬送方向前方となる上方へ向けて物品の下面から押される。ここで、前記仕切り部材１１は、基部１１ａに直交して形成された第１案内部１１ｂに接続され搬送方向前方に向けて傾斜する第２案内部１１ｃが形成されているので、収容区画の底部側を指向する物品の送り方向前方が第１案内部１１ｂに近接するよう搬送コンベヤ１の搬送方向後方側となる下方に向けて傾動する。このようにして、物品Ｗの搬送方向前端が収容区画の底部となる案内レール１６に至るまでに仕切り部材１１の移動によって物品Ｗを押して傾動し、供給コンベヤ２０から前記収容区画に向けた物品Ｗの送り方向への運動エネルギーを吸収するようにしたので、供給コンベヤ２０で高速で搬送されてきた物品Ｗが、案内レール１６に衝突して跳ね返り収容区画から跳びだすのを防止することができ、受入位置Ｐ１で個々の物品Ｗを確実に受入れて排出位置Ｐ２に向けて円滑に搬送することができる。   By the forward movement of the partition member 11, the rear side of the article W from the center of gravity Wp is pushed upward from the lower surface of the article by the third guide portion 11d toward the front in the conveyance direction of the conveyance conveyor 1. Here, since the partition member 11 is formed with the second guide portion 11c that is connected to the first guide portion 11b formed orthogonal to the base portion 11a and is inclined forward in the transport direction, the bottom portion of the storage compartment Tilts downward toward the rear side in the transport direction of the transport conveyor 1 so that the forward direction of the article directed to the side is close to the first guide portion 11b. In this way, the article W is tilted by pushing the article W by the movement of the partition member 11 until the front end in the conveyance direction of the article W reaches the guide rail 16 serving as the bottom of the accommodation section, and the article W directed from the supply conveyor 20 toward the accommodation section. Since the kinetic energy in the feeding direction is absorbed, the article W conveyed at high speed by the supply conveyor 20 can be prevented from colliding with the guide rail 16 and bounced off from the accommodation section. Each article W can be reliably received at the receiving position P1 and smoothly conveyed toward the discharge position P2.

図５は、前記仕切り部材１１を歯付ベルト１０へ取り付ける別実施例を示し、前記歯付ベルト１０における基台１０ｂと仕切り部材１１における基部１１ａとの間に台座３０を取着している。各台座３０は、夫々の仕切り部材１１とともに基台１０ｂに対して着脱可能にネジ止めされている。
台座３０は、搬送方向の前後いずれか一方（本実施例では前方）から水平に突出形成した突出部３０ａと、他方（本実施例では後方）に凹設した凹部３０ｂとを有する。突出部３０ａの突出寸法と凹部３０ｂの凹み寸法はほぼ同一寸法であり、突出部３０ａと凹部３０ｂとが搬送方向前後で相互に係合する。なお、突出部３０ａの先端部上面は、円弧状に形成された曲面に形成されている。 FIG. 5 shows another embodiment in which the partition member 11 is attached to the toothed belt 10, and a pedestal 30 is attached between a base 10 b in the toothed belt 10 and a base 11 a in the partition member 11. Each pedestal 30 is screwed to the base 10b together with the respective partition members 11 so as to be detachable.
The pedestal 30 has a projecting portion 30a that projects horizontally from either the front or rear in the transport direction (front in this embodiment) and a recess 30b that is recessed in the other (rear in this embodiment). The protruding dimension of the protruding part 30a and the recessed dimension of the recessed part 30b are substantially the same, and the protruding part 30a and the recessed part 30b are engaged with each other before and after the conveying direction. Note that the upper surface of the tip of the protrusion 30a is formed in a curved surface formed in an arc shape.

このように台座３０を取着した仕切り部材１１を歯付ベルト１０の各山型歯部１０ａに対応して搬送方向へ連続的に配設して、隣り合う仕切り部材１１同士において、一方（後方）の仕切り部材１１の台座３０の突出部３０ａが、他方（前方）の仕切り部材１１の台座３０の凹部３０ｂへ収容されるようにして係合する。それにより歯付ベルト１０が各歯付プーリ１２、１３に巻き掛けられた転向部Ｌ２及び各転向部Ｌ２を結ぶ直線走行部Ｌ１において、突出部３０ａの上面と凹部３０ｂの天面とが、上下方向（内外方向）で互いに重なって突出部３０ａと凹部３０ｂとが当接して係合する。また、搬送方向に向けて並ぶ先頭の仕切り部材１１に取着した台座３０の前方には、該台座３０の突出部３０ａに係合するストッパ３１が配設される。ストッパ３１は、前記台座３０の凹部３０ｂと同一の凹部３１ａが形成されたストッパ３１が係合している。ストッパ３１の凹部３１ａは、先頭の仕切り部材１１に取着した台座３０の突出部３０ａに係合し、先頭の仕切り部材１１を取着した基台１０ｂの前側に配設した基台１０ｂにネジ止めされている。   Thus, the partition member 11 attached with the base 30 is continuously arranged in the conveying direction corresponding to each chevron tooth portion 10a of the toothed belt 10, and one of the adjacent partition members 11 (rear side) The protrusion 30a of the pedestal 30 of the partition member 11 is engaged so as to be received in the recess 30b of the pedestal 30 of the other (front) partition member 11. Thereby, in the linear travel part L1 which connects the turning part L2 and each turning part L2 in which the toothed belt 10 is wound around each toothed pulley 12, 13, the upper surface of the protrusion part 30a and the top surface of the recessed part 30b are vertically The protrusions 30a and the recesses 30b are brought into contact with each other in the direction (internal and external directions) and engage with each other. Further, a stopper 31 that engages with the protruding portion 30a of the pedestal 30 is disposed in front of the pedestal 30 that is attached to the leading partition member 11 arranged in the transport direction. The stopper 31 is engaged with a stopper 31 in which a concave portion 31 a identical to the concave portion 30 b of the pedestal 30 is formed. The recess 31a of the stopper 31 engages with the protrusion 30a of the base 30 attached to the leading partition member 11, and is screwed onto the base 10b disposed on the front side of the base 10b to which the leading partition member 11 is attached. It has been stopped.

このように構成することで、転向部Ｌ２においては、各仕切り部材１１は先端が八字状に拡がって並ぶ。このとき、各突出部３０ａの前端部上面が、凹部３０ｂの天面に局部的に当接し、またその当接面が曲面となっていることで、突出部３０ａと凹部３０ｂとが円滑に摺動しながら互いの係合状態が維持される。また、直線走行部Ｌ１では、各仕切り部材１１で画成される収容区画は、物品Ｗの前後幅より僅かに広い寸法に設定され、台座３０の前後面同士、及び突出部３０ａの先端と、その先端に対向する凹部３０ｂの奥面とは接触せずに、一定のクリアランスを有している。各仕切り部材１１の歯付ベルト１０への組み付け精度や使用環境の温度差などで生じる歯付ベルト１０の伸縮をクリアランスによって許容することができる。また、転向部Ｌ２において巻き掛けられた歯付ベルト１０が歯付プーリ１２に馴染んで走行でき、歯飛びなどの走行の障害を生ずるようなことがない。   By configuring in this way, in the turning portion L2, the respective partition members 11 are arranged with their tips extending in an eight-letter shape. At this time, the upper surface of the front end of each protrusion 30a is locally in contact with the top surface of the recess 30b, and the contact surface is a curved surface, so that the protrusion 30a and the recess 30b slide smoothly. The mutual engagement state is maintained while moving. Further, in the straight traveling portion L1, the storage compartment defined by each partition member 11 is set to a dimension slightly wider than the front-rear width of the article W, and the front-rear surfaces of the pedestal 30 and the tip of the protruding portion 30a, It has a certain clearance without contacting the inner surface of the recess 30b facing the tip. The expansion and contraction of the toothed belt 10 caused by the accuracy of assembling each partition member 11 to the toothed belt 10 or the temperature difference of the usage environment can be allowed by the clearance. In addition, the toothed belt 10 wound around the turning portion L2 can travel along with the toothed pulley 12, and there is no occurrence of trouble such as tooth skipping.

この実施例によれば、隣り合う各仕切り部材１１は、物品の受入位置Ｐ１に設定された歯付ベルト１０の転向部Ｌ２において、各台座３０の突出部３０ａと凹部３０ｂとが局部的に当接して係合し、互いに二点で支え合うように支持されて各仕切り部材１１の前後への振れが抑止される。これにより、歯付ベルト１０を高速で間欠走行する場合であっても、供給されてくる物品Ｗが各仕切り部材１１間へ搬入される際に、仕切り部材１１が搬送方向前後へ振れて収容区画の入り口が狭まって物品Ｗの搬入を阻害することなく、物品Ｗの収容区画への搬入を円滑且つ確実に行うことができる。   According to this embodiment, each adjacent partition member 11 has a projecting portion 30a and a recessed portion 30b of each pedestal 30 that locally contact each other at the turning portion L2 of the toothed belt 10 set at the article receiving position P1. The partition members 11 are restrained from swinging forward and backward by being in contact with each other and supported so as to support each other at two points. Accordingly, even when the toothed belt 10 is intermittently traveled at a high speed, when the supplied article W is carried between the partition members 11, the partition member 11 is swung back and forth in the conveying direction. The entrance of the article W can be smoothly and reliably carried into the storage compartment without the entrance of the article being narrowed and hindering the delivery of the article W.

また、各仕切り部材１１の凹部３０ｂの天面は、転向部Ｌ２の曲面に沿って傾斜させておくことが好ましい。これにより、軟質の歯付ベルト１０においても、転向部Ｌ２において、突出部３０ａと凹部３０ｂとの係合状態を確実に維持することができる。   Moreover, it is preferable to incline the top | upper surface of the recessed part 30b of each partition member 11 along the curved surface of the turning part L2. Thereby, also in the soft toothed belt 10, the engagement state of the protrusion part 30a and the recessed part 30b can be reliably maintained in the turning part L2.

前記各実施例では、無端索条体は、歯付ベルトとして例示したが、チェーンを採用してもよい。又、搬送コンベヤの上流側転向部に対して、物品を供給コンベヤに載置して水平に送り込む形態としたが、搬送コンベヤの物品受け入れ位置は、斜め上方からコンベヤ又はシュートなどによって送り込む形態や、上方から落下供給する各種の送り込み形態を採用することもできる。
又、仕切り部材は、板状材を折り曲げ形成するように構成したが、少なくとも、その先端部おいて第１案内部を備えたものであれば、適宜の形状の仕切り部材を採用することができる。
前記実施例における搬送コンベヤでは、２つの無端索条体を併設して、それぞれ別のサーボモータで走行駆動する構成であるが、１又は３以上の複数の無端索条体を採用するものでもよい。
