前記特許文献１に開示された選別搬送装置の発明によれば、搬送ベルト上に所定間隔で設けた突起と突起の間に長体状の被搬送物を保持し、後工程に向けて搬送しているが、搬送ベルト上に被搬送物が多数個が載っている場合に余分な被搬送物を落とすとともに、突起間で保持している被搬送物を所定位置に揃えるため、この搬送ベルトは上方に向けて傾斜しているだけでなく、側方にねじれるように傾斜している。このため、特に搬送対象としているような根菜類のような円柱状の被搬送物の場合には、上に重なったものだけでなく所定位置に保持されているものも落ちてしまったり、又は条件によっては全く両者とも落下しない等、必要なものだけ残して余分なものは落下させるという当初の目的の達成は必ずしも確実ではないという問題があった。 According to the invention of the sorting and conveying apparatus disclosed in Patent Document 1, a long object to be conveyed is held between protrusions provided on a conveyor belt at predetermined intervals, and conveyed to a subsequent process. However, when there are a large number of objects to be conveyed on the conveyor belt, the excess conveyor objects are dropped and the object to be conveyed held between the protrusions is aligned at a predetermined position. In addition to being inclined upward, it is inclined so as to be twisted to the side. For this reason, in particular, in the case of a cylindrical object to be transported such as a root vegetable that is to be transported, not only those that are superimposed on top but also those that are held in place or fall off or conditions In some cases, both of them do not fall at all, and there is a problem that it is not always certain to achieve the initial purpose of leaving only the necessary ones and dropping the extra ones.

請求項２に記載された供給装置１，５０は、請求項１記載の供給装置において、
前記振動手段２０は、モータ１２に駆動されて回転することにより前記搬送ベルト１１に下面側から振動を与える振動部材２２を有していることを特徴としている。 The supply device 1 , 50 described in claim 2 is the supply device according to claim 1 ,
The vibration means 20 includes a vibration member 22 that rotates by being driven by a motor 12 to apply vibration to the conveyor belt 11 from the lower surface side.

請求項３に記載された供給装置１，５０は、請求項２記載の供給装置において、
前記搬送手段７の傾斜角度が調整自在であり、前記振動部材２２が前記搬送ベルト１１に与える振動の状態を前記傾斜角度に応じて変更することを特徴としている。 The supply device 1, 50 described in claim 3 is the supply device according to claim 2 ,
The inclination angle of the conveying means 7 is adjustable, and the state of vibration that the vibration member 22 gives to the conveying belt 11 is changed according to the inclination angle.

請求項１に記載された供給装置によれば、傾斜した搬送手段の底部である上流において、多数の被搬送物が搬送ベルト上にまとめて供給される。上昇方向に移動していく搬送ベルトの上では、積み込まれた多数の被搬送物が互いに重なり合った不規則な状態にあるが、上方に向けて搬送されていく中で、搬送ベルトの各係止部及びその近傍には、１個又は２個以上の被搬送物が係止され又は留められた状態となる。この搬送中に、被搬送物を保持している搬送ベルトは振動手段の作用によって振動を受ける。振動を受けても、搬送ベルトの係止部に１個だけで安定して係止されている被搬送物は落下しないが、係止部に２個以上が存在する場合は、当該係止部に安定して係止されている１個の被搬送物だけを残して、これ以外の不安定な搬送状態にある被搬送物は振動により係止部乃至その近傍から外れ、搬送ベルトから回収手段の案内面に落下する。落下した被搬送物は案合面に沿って下方に滑り落ち、被搬送物が供給される搬送手段の上流に戻る。一方、不安定な被搬送物が落下した搬送ベルトでは、各係止部に１個ずつ安定して係止された被搬送物以外には被搬送物は存在せず、被搬送物は搬送方向に所定間隔で並んだ状態になっている。従って、これら被搬送物は係止部の間隔を保ちつつ整然と搬送され、その一定間隔で後段の工程に順に供給されていく。
また、この供給装置によれば、被搬送物を載せて上昇している搬送ベルトの下面側に直接振動を与えるので、搬送ベルトの上に載っている被搬送物に対する振動の伝達が確実であり、搬送ベルトの上に載っている被搬送物のうち、係止部に安定して係止されていないものを確実に回収手段の案内面に落下させることができる。
また、この供給装置によれば、容器部に多数の被搬送物を収納しておくことにより、搬送手段の上流において、上方に向けて移動していく搬送ベルトの上に被搬送物を次々と供給することができる。また、搬送中に、振動手段の作用により搬送ベルトから外れ、回収手段の案内面に落ちた被搬送物は、案内面を滑り落ちて容器部に戻り、搬送ベルトに対する再度の供給に供される。そして、容器部は、下方にある搬送ベルトに向けて内部が狭くなる形態となっており、上部の開口から投入された被搬送物は順次下方に移動して循環する搬送ベルトに供給され、容器部外に搬出されるようになっている。また容器部には回収手段の案内面が連続しているため、案内面を滑り落ちてきた被搬送物はホッパに戻って再びベルトコンベアに供給されることになる。 According to the supply device of the first aspect, a large number of objects to be conveyed are collectively supplied onto the conveying belt at the upstream which is the bottom of the inclined conveying means. On the conveyor belt moving in the upward direction, a large number of loaded objects are in an irregular state where they overlap each other, but each conveyor belt is locked while being conveyed upward. One or two or more objects to be conveyed are locked or fastened in the vicinity of the part and the vicinity thereof. During this transport, the transport belt holding the transported object is vibrated by the action of the vibration means. Even if it receives vibration, the object to be transported that is stably locked to only one locking portion of the conveyor belt does not fall, but when there are two or more locking portions, the locking portion Only one object to be transported that is stably locked to the rest, and the other transported object that is in an unstable transport state is detached from the locking portion or its vicinity by vibration, and is recovered from the transport belt. Fall on the guide surface. The fallen object to be transported slides down along the mating surface and returns to the upstream of the transport means to which the object is supplied. On the other hand, in the conveyance belt in which an unstable conveyance object has fallen, there is no conveyance object other than the conveyance object that is stably locked one by one in each locking portion, and the conveyance object is in the conveyance direction. Are arranged at predetermined intervals. Accordingly, these objects to be conveyed are conveyed in an orderly manner while maintaining the interval between the locking portions, and are sequentially supplied to the subsequent processes at regular intervals.
Further, according to this supply device, vibration is directly applied to the lower surface side of the conveyor belt that is moving up with the object to be conveyed, so that the transmission of vibration to the object to be conveyed placed on the conveyor belt is reliable. Of the articles to be transported that are placed on the transport belt, those that are not stably locked to the locking portion can be reliably dropped onto the guide surface of the collecting means.
Further, according to this supply apparatus, by storing a large number of objects to be conveyed in the container portion, the objects to be conveyed are successively placed on the conveying belt that moves upward, upstream of the conveying means. Can be supplied. Further, during transportation, the object to be transported, which is detached from the transport belt by the action of the vibration means and falls on the guide surface of the collecting means, slides down the guide surface and returns to the container portion, and is supplied to the transport belt again. . The container portion has a configuration in which the inside becomes narrower toward the lower conveyor belt, and the articles to be conveyed thrown through the upper opening are sequentially supplied to the conveyor belt that moves downward and circulates. It is designed to be carried outside. Further, since the guide surface of the collecting means is continuous in the container portion, the object to be conveyed that has slid down the guide surface returns to the hopper and is supplied to the belt conveyor again.

請求項２に記載された供給装置によれば、搬送ベルトの下面側に接触させた振動部材をモータの駆動力で回転させているので、搬送ベルトを確実かつ効果的に振動させることができ、搬送ベルト上にある不安定な被搬送物を確実に移動させて回収手段へ落下させることができる。また、モータの駆動条件や振動部材の外形を変更することで、被搬送物の形状等に対応して、搬送ベルトに与える振動の状態を任意に変化させることができる。 According to the supply device described in claim 2 , since the vibrating member brought into contact with the lower surface side of the conveyor belt is rotated by the driving force of the motor, the conveyor belt can be vibrated reliably and effectively. An unstable object to be conveyed on the conveyor belt can be reliably moved and dropped to the collecting means. In addition, by changing the driving conditions of the motor and the outer shape of the vibration member, the state of vibration applied to the conveyor belt can be arbitrarily changed according to the shape of the object to be conveyed.

請求項３に記載された供給装置によれば、設置場所の広狭や、被搬送物の供給対象である後段装置等の構造等に応じて、搬送手段の傾斜角度を自在に調整することができるので、被搬送物に係る生産ライン等を構成する際の自由度が高い。また、設定した搬送手段の傾斜角度に応じて搬送ベルトの振動状態を変更することができるので、搬送手段の傾斜角度に対応した最適な振動で不安定な被搬送物の排除を確実に行うことができる。例えば、搬送手段の傾斜角度が相対的に大きければ、相対的に小さい場合に比べて被搬送物は係止部から外れやすいので、振動は相対的に小さくする。また、搬送手段の傾斜角度が相対的に小さければ、相対的に大きい場合に比べて被搬送物は係止部から外れにくいので、振動は相対的に大きくする。 According to the third aspect of the present invention, the inclination angle of the conveying means can be freely adjusted according to the size of the installation location, the structure of the subsequent apparatus, etc., to which the object to be conveyed is supplied. Therefore, there is a high degree of freedom when configuring a production line or the like related to the conveyed object. In addition, since the vibration state of the conveyor belt can be changed according to the set inclination angle of the conveying means, it is possible to surely eliminate unstable conveyed objects with the optimum vibration corresponding to the inclination angle of the conveying means. Can do. For example, if the inclination angle of the conveying means is relatively large, the object to be conveyed is likely to be detached from the locking portion as compared with the case where the inclination is relatively small, so that the vibration is relatively small. Also, if the inclination angle of the conveying means is relatively small, the object to be conveyed is less likely to come off from the locking portion than when it is relatively large, so the vibration is relatively large.

本発明の第１実施形態を図１〜図６を参照して説明する。
まず、この供給装置１の構成を説明する。
第１実施形態の供給装置１は、具体的な一例を挙げれば、ホタテ貝の貝柱の冷凍品の選別ラインに設置される。このラインでは、この供給装置１によって被搬送物Ｗを所定間隔おいた１列の状態にして運び、図１及び図２に示すように後段の重量測定装置２で１個ずつ重量を測定する。さらに重量測定装置２での測定結果を元にして、詳細は図示しないが、さらに後段の重量選別装置３で重量別に選別して複数の等級（サイズ）に分類する。このように重量に基づいて製品を複数の等級（サイズ）に分類する必要上、重量測定装置２には製品を１個ずつ所定間隔で搬入して正確に重量測定する必要があり、２個以上が同時に送り込まれることは避けねばならない。本実施形態の供給装置１は、このような選別ラインにおける必要から、被搬送物Ｗを後段の装置に所定間隔で１個ずつ供給することために設けられたものである。 A first embodiment of the present invention will be described with reference to FIGS.
First, the configuration of the supply device 1 will be described.
The supply apparatus 1 of 1st Embodiment will be installed in the sorting line of the frozen product of the scallop shell, if a specific example is given. In this line, the articles to be conveyed W are carried in a line at a predetermined interval by the supply device 1, and the weights are measured one by one with the subsequent weight measuring device 2 as shown in FIGS. 1 and 2. Further, based on the measurement result of the weight measuring device 2, although not shown in detail, it is further sorted according to weight by the weight sorting device 3 at the subsequent stage and classified into a plurality of grades (sizes). As described above, it is necessary to classify products into a plurality of grades (sizes) based on the weight, and it is necessary to accurately carry out weight measurement by bringing the products into the weight measuring device 2 at predetermined intervals. Must be sent at the same time. The supply device 1 of the present embodiment is provided to supply the articles to be conveyed W one by one to the subsequent apparatus at a predetermined interval because of the necessity in such a sorting line.

この供給装置１による被搬送物Ｗであるホタテ貝柱の冷凍品（以下、単に被搬送物Ｗと呼ぶ）は、直径に比して高さの小さい円柱状又は半球状又はドーム状のような概ね丸い外形の固体状の塊体であり、その底面は比較的平らで載置面に安定して接することができるようなものである。 A scallop frozen product (hereinafter simply referred to as “conveyed object W”) that is the object to be conveyed W by the supply device 1 is generally in a columnar shape, a hemispherical shape, or a dome shape whose height is smaller than the diameter. It is a solid mass with a round outer shape, and its bottom surface is relatively flat so that it can stably contact the mounting surface.

図１及び図４に示すように、本実施形態の供給装置１は、後述する搬送手段を設置して後段の装置につなげるための基台４を有している。基台４は、下フレーム部５と、被搬送物Ｗの搬送方向について下フレーム部５の下流側の端部に設けられた架台部６とから構成されている。架台部６の高さは、後段の重量測定装置２の導入コンベア２ａに被搬送物Ｗを送り込むのに適した高さに設定されている。 As shown in FIGS. 1 and 4, the supply device 1 according to the present embodiment includes a base 4 for installing a later-described transport unit and connecting it to a subsequent device. The base 4 includes a lower frame portion 5 and a gantry portion 6 provided at an end portion on the downstream side of the lower frame portion 5 in the conveyance direction of the conveyed object W. The height of the gantry 6 is set to a height suitable for feeding the article to be conveyed W to the introduction conveyor 2a of the weight measuring device 2 at the subsequent stage.

図１乃至図４に示すように、基台４の上には搬送手段としてのベルトコンベア７が設置されている。このベルトコンベア７の下流側の端部（高さの面では最高部）は、基台４の架台部６の上に取り付けられており、搬送された被搬送物Ｗが隣接する重量測定装置２の導入コンベア２ａに乗り移れるようになっている。このベルトコンベア７の上流側の端部（高さの面では最低部）は、基台４の下フレーム部５の上方において、架台部６上の下流側よりも低い位置に配置され、下フレーム部５に対して支持部材８で連結されて位置固定されている。従って、ベルトコンベア７は、搬送方向に向けて被搬送物Ｗが上昇するような傾斜角度で設置されている。ベルトコンベア７を支える支持部材８は、ベルトコンベア７に対して上端部が回動可能に連結されており、下端部が下フレーム部５の数カ所に設けられた固定部の一箇所に着脱可能に固定されている。従って、ベルトコンベア７を支えた状態で支持部材８の下端部を下フレーム部５から外し、ベルトコンベア７の傾斜角度を変更し、ベルトコンベア７の姿勢を保持しながら支持部材８の下端部を下フレーム部５の他の適当な固定部に固定すれば、ベルトコンベア７の傾斜角度を任意に設定・変更することができる。 As shown in FIGS. 1 to 4, a belt conveyor 7 serving as a conveying unit is installed on the base 4. The downstream end portion (the highest portion in terms of height) of the belt conveyor 7 is mounted on the gantry 6 of the base 4, and the weight measuring device 2 to which the conveyed object W is conveyed is adjacent. Can be transferred to the introduction conveyor 2a. The upstream end (the lowest part in terms of height) of the belt conveyor 7 is disposed above the lower frame portion 5 of the base 4 at a position lower than the downstream side on the gantry 6, and the lower frame It is connected to the part 5 by a support member 8 and fixed in position. Accordingly, the belt conveyor 7 is installed at an inclination angle such that the conveyed object W rises in the conveyance direction. The support member 8 that supports the belt conveyor 7 is connected to the belt conveyor 7 so that the upper end portion thereof is pivotable, and the lower end portion thereof can be attached to and detached from one place of the fixing portion provided at several places of the lower frame portion 5. It is fixed. Accordingly, the lower end portion of the support member 8 is removed from the lower frame portion 5 while the belt conveyor 7 is supported, the inclination angle of the belt conveyor 7 is changed, and the lower end portion of the support member 8 is held while maintaining the posture of the belt conveyor 7. If the belt frame 7 is fixed to another appropriate fixing portion, the inclination angle of the belt conveyor 7 can be arbitrarily set and changed.

図１乃至図４に示すように、ベルトコンベア７は、その上流側の端部に設けられた従動プーリ９と、下流側の端部に設けられた駆動プーリ１０との間に、無端の搬送ベルト１１を掛け回してなる搬送手段であるが、基台４の架台部６に設けられた駆動モータ１２によって駆動プーリ１０を駆動することにより、搬送ベルト１１が下流に向けて登っていくように運転される。また、詳細は図示しないが、架台部６の上にあるベルトコンベア７の下流側の端部には、搬送ベルト１１の張力を調整するテンション機構が設けられており、搬送ベルト１１の張力を調整することができるようになっている。 As shown in FIGS. 1 to 4, the belt conveyor 7 is transported endlessly between a driven pulley 9 provided at an upstream end thereof and a drive pulley 10 provided at a downstream end thereof. It is a conveying means that wraps around the belt 11, and the driving pulley 10 is driven by a driving motor 12 provided on the gantry 6 of the base 4 so that the conveying belt 11 climbs downstream. Driven. Although not shown in detail, a tension mechanism for adjusting the tension of the conveyor belt 11 is provided at the downstream end of the belt conveyor 7 on the gantry 6, and the tension of the conveyor belt 11 is adjusted. Can be done.

図４及び図５に示すように、ベルトコンベア７の搬送ベルト１１は、無端状の平ベルトの搬送面に、搬送方向に沿って所定間隔で複数の係止部１３が突出して設けられた構造となっている。係止部１３は、搬送ベルト１１の搬送面から垂直方向に立ち上がった矩形状の板体であって二枚一組で構成される。一組二枚の係止部１３，１３は、互いに所定間隔を置き、かつ所定の角度（本実施形態では例えば１２０度）を以て下流側（高い側）に向けてハの字状に開いた状態に配置されている。このように、一組二枚の係止部１３，１３の間には隙間があるので、水分や破片等を生じやすい被搬送物Ｗを搬送する際には、この隙間から水分や破片等が下方に落ちるので好都合である。 As shown in FIGS. 4 and 5, the conveyor belt 11 of the belt conveyor 7 has a structure in which a plurality of locking portions 13 protrude from the conveyor surface of an endless flat belt at predetermined intervals along the conveyor direction. It has become. The locking portion 13 is a rectangular plate that rises in the vertical direction from the conveyance surface of the conveyance belt 11 and is formed of a set of two sheets. The set of two locking portions 13 and 13 are spaced apart from each other and opened in a C shape toward the downstream side (high side) at a predetermined angle (for example, 120 degrees in this embodiment). Is arranged. In this way, since there is a gap between the pair of two locking portions 13, 13, when transporting the article to be transported W that is likely to generate moisture, debris, etc., moisture, debris, etc. from this gap. It is convenient because it falls downward.

なお、この係止部１３の構造は本実施形態における被搬送物Ｗの外形に合わせたものであり、係止部１３の形状、個数、配置等は上述したものに限定する必要はなく、被搬送物Ｗの外形に合わせて１個だけを安定して保持することで定間隔搬送を可能とし、２個載りした場合には、係止部１３に安定して載ったもの以外は支持が不安定で落下しやすくなるような構造であればよい。 The structure of the locking portion 13 is adapted to the outer shape of the conveyed object W in the present embodiment, and the shape, number, arrangement, etc. of the locking portion 13 do not need to be limited to those described above. By stably holding only one piece according to the outer shape of the conveyed product W, it is possible to carry it at regular intervals, and when two pieces are placed, there is no support other than those stably placed on the locking portion 13. Any structure that is stable and easily drops can be used.

従って、図５中に想像線で示すように、被搬送物Ｗは、傾斜した搬送ベルト１１上で上方に向けて開いた一対の係止部１３，１３の間に受け止められ、安定して保持される。係止部１３の寸法は、被搬送物Ｗの標準的な外径に応じて適当に設定されており、一箇所の係止部１３，１３に一個の被搬送物Ｗは安定して支持できるが、二個以上の被搬送物Ｗは一箇所の係止部１３，１３に安定して載ることができないようになっている。すなわち、図５中に想像線で示した被搬送物Ｗを見れば分かるように、一箇所の係止部１３，１３に一個の被搬送物Ｗが載った場合は、この被搬送物Ｗは外周面の二箇所で二枚の係止部１３，１３にそれぞれ接して安定するが、二個以上の被搬送物Ｗが一箇所の係止部１３，１３に載った場合は、一方の被搬送物Ｗは係止部１３に安定して支持されるが、他方の被搬送物Ｗは係止部１３による支持が不十分であり、大抵は係止部１３に安定して支持された一方の被搬送物Ｗに不安定な状態で載った状態となる。従って、この状態で搬送ベルト１１が振動すると、不安定な被搬送物Ｗは係止部１３から外れて搬送ベルト１１の傾斜に従って落下することになる。 Therefore, as shown by an imaginary line in FIG. 5, the article W to be conveyed is received between the pair of locking portions 13 and 13 opened upward on the inclined conveyor belt 11 and stably held. Is done. The dimension of the latching | locking part 13 is set suitably according to the standard outer diameter of the to-be-conveyed object W, and the one to-be-conveyed object W can be stably supported by the latching | locking parts 13 and 13 of one place. However, two or more objects to be conveyed W cannot be stably placed on the locking portions 13 and 13 at one place. That is, as can be seen by looking at the conveyed object W indicated by the imaginary line in FIG. 5, when one conveyed object W is placed on one locking portion 13, 13, the conveyed object W is The two locking portions 13 and 13 are in contact with each other at two locations on the outer peripheral surface to be stable. However, when two or more articles to be transported W are placed on the locking portions 13 and 13 at one location, The transported object W is stably supported by the locking part 13, but the other transported object W is not sufficiently supported by the locking part 13, and is usually supported stably by the locking part 13. It will be in the state put on the to-be-conveyed object W of the instability state. Accordingly, when the conveyor belt 11 vibrates in this state, the unstable article W is detached from the locking portion 13 and falls according to the inclination of the conveyor belt 11.

図２及び図４に示すように、ベルトコンベア７の搬送方向と直交する幅方向について、ベルトコンベア７を挟む両側の位置には、被搬送物Ｗの回収手段１５が設けられている。この回収手段１５は、ベルトコンベア７の上記両側位置において、搬送方向に沿ってベルトコンベア７に接して設けられた長手トレイ状の案内部材であり、ベルトコンベア７と同じ傾斜角度を有し、その案内面は搬送ベルト１１の搬送面よりも下方に設定されている。 As shown in FIGS. 2 and 4, the collection means 15 for the object to be conveyed W is provided at positions on both sides of the belt conveyor 7 in the width direction orthogonal to the conveyance direction of the belt conveyor 7. The collecting means 15 is a longitudinal tray-shaped guide member provided in contact with the belt conveyor 7 along the conveying direction at the both side positions of the belt conveyor 7 and has the same inclination angle as the belt conveyor 7. The guide surface is set below the transport surface of the transport belt 11.

図１乃至図４に示すように、ベルトコンベア７の上流側の端部（高さの面では最低部）には、ベルトコンベア７と回収手段１５を囲むようにして、被搬送物Ｗの容器部であるホッパ１６が設けられている。図３に示すようにホッパ１６は一対の回収手段１５，１５と幅が略同一であり、回収手段１５，１５を挟んで対向する搬送方向と平行な逆三角形状の２面の側壁部１６ａと、２面の側壁部１６ａの上流側を連結する上縁が外方に傾斜した矩形状の後壁部１６ｂとを有しており、上面及び下面が開口とされた全体として三角柱状の中空筐体である。従ってホッパ１６は、下方にある搬送ベルト１１に向けて内部が狭くなる形態となっており、上部の開口１６ｃから投入された被搬送物Ｗは順次下方に移動して循環する搬送ベルト１１に供給され、ホッパ１６外に搬出されるようになっている。またホッパ１６には回収手段１５の案内面が連続しているため、案内面を滑り落ちてきた被搬送物Ｗはホッパ１６に戻って再びベルトコンベア７に供給されることになる。 As shown in FIGS. 1 to 4, the upstream end of the belt conveyor 7 (the lowest part in terms of height) surrounds the belt conveyor 7 and the collecting means 15, and is a container portion of the object W to be conveyed. A hopper 16 is provided. As shown in FIG. 3, the hopper 16 has substantially the same width as the pair of collection means 15, 15, and has two inverted triangular side wall portions 16 a parallel to the conveying direction across the collection means 15, 15. And a rectangular rear wall portion 16b whose upper edge connecting the upstream side of the two side wall portions 16a is inclined outward, and a hollow housing having a triangular prism shape as a whole with an upper surface and a lower surface being opened. Is the body. Accordingly, the hopper 16 has a configuration in which the inside becomes narrower toward the lower conveyor belt 11, and the article W to be conveyed introduced from the upper opening 16 c sequentially moves downward and is supplied to the circulating conveyor belt 11. Then, it is carried out of the hopper 16. Further, since the guide surface of the collecting means 15 is continuous with the hopper 16, the conveyed object W that has slid down the guide surface returns to the hopper 16 and is supplied to the belt conveyor 7 again.

図１及び図２に示すように、ベルトコンベア７には、搬送ベルト１１上の不安定な被搬送物Ｗを係止部１３から落とすために搬送ベルト１１を振動させる振動手段２０が設けられている。本実施形態の振動手段２０は複数個（本実施形態では３個）であり、搬送方向に沿って適宜の間隔をおいて設けられている。これら振動手段２０は、上下の搬送ベルト１１の間を通って左右の回収手段１５の間に渡設された回動軸２１と、この回動軸２１の中央に設けられた振動部材２２と、回収手段１５のフレームに取り付けられて駆動軸が回動軸２１に連動連結された振動モータ２３とを有している。 As shown in FIGS. 1 and 2, the belt conveyor 7 is provided with a vibrating means 20 that vibrates the conveyor belt 11 in order to drop the unstable object W on the conveyor belt 11 from the engaging portion 13. Yes. There are a plurality (three in this embodiment) of vibration means 20 of the present embodiment, and they are provided at appropriate intervals along the transport direction. The vibrating means 20 includes a rotating shaft 21 that is passed between the upper and lower conveying belts 11 and between the left and right collecting means 15, and a vibrating member 22 that is provided at the center of the rotating shaft 21. A vibration motor 23 is attached to the frame of the collecting means 15 and the drive shaft is interlocked and connected to the rotation shaft 21.

図６に拡大して示すように、回動軸２１は、ベルトコンベア７の搬送ベルト１１の幅方向に対して平行である。また、この回動軸２１に取りつけられた振動部材２２は、回動軸２１と平行な視線で見た場合の形状が略正方形状であり、その角は面取り又は曲面加工されている。振動部材２２は、被搬送物Ｗが載る上側の搬送ベルト１１の下面に接するように配置されている。従って、振動モータ２３が駆動されると、振動部材２２が回転して搬送ベルト１１を周期的に上下動させて振動を発生させ、搬送ベルト１１上の被搬送物Ｗに振動を与える。これによって、搬送ベルト１１上で係止部１３に安定して係止されていない不安定な被搬送物Ｗは係止部１３から外れ、搬送ベルト１１から回収手段１５の案内面に落下する。なお、振動部材２２の形状は、上述したような略正方形状に限らず、角が丸い三角形状、楕円形状、又は回動軸２１に偏芯して取り付けられた円形等でもよく、このような外形・構造の異なる振動部材２２に変更することにより、搬送ベルト１１に与える振動を任意に変更することができる。 As shown in an enlarged view in FIG. 6, the rotation shaft 21 is parallel to the width direction of the transport belt 11 of the belt conveyor 7. Further, the vibration member 22 attached to the rotating shaft 21 has a substantially square shape when viewed from a line of sight parallel to the rotating shaft 21, and the corners thereof are chamfered or curved. The vibration member 22 is disposed so as to be in contact with the lower surface of the upper conveyor belt 11 on which the article to be conveyed W is placed. Therefore, when the vibration motor 23 is driven, the vibration member 22 rotates to periodically move the conveyor belt 11 up and down to generate vibrations, and the object W on the conveyor belt 11 is vibrated. As a result, the unstable conveyed object W that is not stably locked to the locking portion 13 on the transport belt 11 is detached from the locking portion 13 and falls from the transport belt 11 to the guide surface of the collecting means 15. The shape of the vibration member 22 is not limited to the substantially square shape as described above, but may be a triangular shape with rounded corners, an elliptical shape, or a circular shape eccentrically attached to the rotating shaft 21. By changing to the vibrating member 22 having a different external shape and structure, the vibration applied to the conveyor belt 11 can be arbitrarily changed.

次に、以上説明した供給装置１による被搬送物Ｗの搬送作用について説明する。
供給装置１のベルトコンベア７において、上流側の低い部分に設けられたホッパ１６の開口１６ｃから、ホッパ１６の容積を限度として所望の量の被搬送物Ｗを供給する。これにより、後工程の重量測定装置２等に供するのに十分な又は必要な量の被搬送物Ｗをホッパ１６内にストックした状態で後段への供給作業を開始することができる。 Next, the transporting operation of the transported object W by the supply device 1 described above will be described.
In the belt conveyor 7 of the supply device 1, a desired amount of the object W to be conveyed is supplied from the opening 16 c of the hopper 16 provided in the lower portion on the upstream side, with the volume of the hopper 16 as a limit. Thereby, the supply operation | work to a back | latter stage can be started in the state which stocked the to-be-conveyed object W enough or required quantity to use for the weight measuring apparatus 2 grade | etc., Of a post process.

ホッパ１６の底部では、積み込まれた多数の被搬送物Ｗが互いに重なり合った不規則な状態にあるが、搬送ベルト１１が上昇方向に移動していく中で、図４及び図５に示すように、搬送ベルト１１の各係止部１３及びその近傍には１個又は２個以上の被搬送物Ｗが係止され又は引っ掛かった状態となる。これらの被搬送物Ｗはホッパ１６の外に運び出されて、後段の重量測定装置２に向けて上昇しながら搬送されていく。 At the bottom of the hopper 16, a large number of loaded articles W are in an irregular state where they overlap each other. As the conveyor belt 11 moves in the upward direction, as shown in FIGS. In addition, one or two or more objects to be conveyed W are locked or caught in the respective locking portions 13 of the conveying belt 11 and the vicinity thereof. These objects to be conveyed W are carried out of the hopper 16 and conveyed while rising toward the weight measuring device 2 at the subsequent stage.

この搬送中、図６に示すように、被搬送物Ｗを載せて上昇している搬送ベルト１１は、振動モータ２３で回転する振動部材２２によってその下面側から直接振動が与えられる。振動を受けると、図４に示すように、搬送ベルト１１の係止部１３に１個だけで安定して係止されている被搬送物Ｗは落下しないが、係止部１３に２個以上が存在する場合には、当該係止部１３に安定して係止されている１個の被搬送物Ｗだけが残り、これ以外の不安定な被搬送物Ｗは振動によって係止部１３乃至その近傍から外れ、搬送ベルト１１から回収手段１５の案内面に落下する。落下した被搬送物Ｗは回収手段１５に沿って下方に滑り落ち、ホッパ１６内に戻る。 During this conveyance, as shown in FIG. 6, the conveyor belt 11 that is moving up with the article W to be conveyed is directly vibrated from the lower surface side thereof by the vibration member 22 that is rotated by the vibration motor 23. When receiving the vibration, as shown in FIG. 4, the object to be transported W that is stably locked to only one locking portion 13 of the conveying belt 11 does not fall, but two or more objects are locked to the locking portion 13. Is present, only one transported object W that is stably locked to the locking part 13 remains, and the other unstable transported object W remains in the locking parts 13 to 13 due to vibration. It comes off from its vicinity and falls from the conveyor belt 11 to the guide surface of the collecting means 15. The fallen transported object W slides down along the collecting means 15 and returns into the hopper 16.

このように、係止部１３から外れた不安定な被搬送物Ｗは、搬送面から直ちに回収手段１５の案内面に落ちて回収されるので、搬送ベルト１１の上を滑落して係止部１３に安定して係止された上流（下方）の被搬送物Ｗに衝突してこれを落下させてしまうことがない。そして、不安定な被搬送物Ｗが落下した搬送ベルト１１の上部では、各係止部１３に被搬送物Ｗが１個ずつ係止され、被搬送物Ｗが搬送方向に所定間隔で並んだ状態になっている。これら被搬送物Ｗは所定間隔で後段の工程に順次供給されていく。 In this way, the unstable transported object W that has come off from the latching portion 13 immediately falls on the guide surface of the collecting means 15 from the transport surface and is collected. No collision occurs with the upstream (downward) transported object W that is stably locked to 13 and dropped. And in the upper part of the conveyance belt 11 where the unstable conveyance object W has fallen, the conveyance object W is locked one by one to each locking portion 13, and the conveyance object W is arranged at a predetermined interval in the conveyance direction. It is in a state. These conveyed objects W are sequentially supplied to the subsequent process at predetermined intervals.

従って、後段の重量測定装置２では、供給装置１から所定間隔で送り込まれてくる被搬送物Ｗを、その間隔に合わせた所定のタイミングで次々と能率的に測定していくことができ、無駄な待ち時間や、２個以上の被搬送物Ｗが同時に搬入されたり、区別が困難な間隔で搬入されることがなく、安定した正確な測定を行なうことができる。従って、さらに後段の重量選別装置３における振り分け作業の能率も向上し、ライン全体の生産性を高めることができる。 Therefore, the latter-stage weight measuring device 2 can efficiently and efficiently measure the workpieces W fed from the supply device 1 at a predetermined interval one after another at a predetermined timing according to the interval. A stable waiting time and two or more objects to be conveyed W are not carried in at the same time or are carried in at intervals that are difficult to distinguish, and stable and accurate measurement can be performed. Therefore, the efficiency of the sorting operation in the subsequent weight selection device 3 can be improved, and the productivity of the entire line can be increased.

また、この供給装置１によれば、設置場所の広狭や、被搬送物Ｗの供給対象である後段装置等の構造等に応じて、ベルトコンベア７の傾斜角度を自在に調整することができる。例えば、図１に示すように傾斜が緩い状態では、ベルトコンベア７の端部は下フレーム部５の外形に近接し、又はやや外に突出した状態にある。しかし、工場内におけるラインの設置面積による制約や、他の機器等との干渉を避ける必要がある場合には、ベルトコンベア７の傾斜角度がより急になるように支持部材８の取り付け位置を変更し、ベルトコンベア７の端部を下フレーム部５の設置範囲内に収まるようにすればよい。また、後段装置が被搬送物Ｗを受け入れる高さに変更があった場合は、やはり支持部材８の取り付け位置を変えてベルトコンベア７の傾斜角度を変更し、ベルトコンベア７の下流側の端部の高さを後段装置に合わせればよい。このように、本実施形態の供給装置１によれば、被搬送物Ｗに係る生産ライン等を構成する際の自由度が高い。 Further, according to the supply device 1, the inclination angle of the belt conveyor 7 can be freely adjusted according to the size of the installation location, the structure of the subsequent device or the like that is the supply target of the transported object W, and the like. For example, in a state where the inclination is gentle as shown in FIG. 1, the end portion of the belt conveyor 7 is close to the outer shape of the lower frame portion 5 or slightly protrudes outward. However, if it is necessary to avoid restrictions due to the installation area of the line in the factory or interference with other equipment, the mounting position of the support member 8 is changed so that the inclination angle of the belt conveyor 7 becomes steeper. Then, the end portion of the belt conveyor 7 may be set within the installation range of the lower frame portion 5. Further, when there is a change in the height at which the latter apparatus receives the object to be conveyed W, the inclination angle of the belt conveyor 7 is also changed by changing the mounting position of the support member 8, and the downstream end of the belt conveyor 7 is changed. Can be adjusted to the height of the latter apparatus. Thus, according to the supply apparatus 1 of this embodiment, the freedom degree at the time of comprising the production line etc. which concern on the to-be-conveyed object W is high.

また、本実施形態の供給装置１によれば、設定したベルトコンベア７の傾斜角度に応じて、振動部材２２が搬送ベルト１１に与える振動の状態を変更するようにしてもよい。例えば、ベルトコンベア７の傾斜角度が相対的に大きければ、相対的に小さい場合に比べて被搬送物Ｗは係止部１３から外れやすいので、振動は相対的に小さくてよい。また、ベルトコンベア７の傾斜角度が相対的に小さければ、相対的に大きい場合に比べて被搬送物Ｗは係止部１３から外れにくいので、振動は相対的に大きくする必要がある。 Further, according to the supply device 1 of the present embodiment, the state of vibration that the vibration member 22 applies to the transport belt 11 may be changed according to the set inclination angle of the belt conveyor 7. For example, if the inclination angle of the belt conveyor 7 is relatively large, the conveyed object W is likely to be detached from the locking portion 13 as compared with the case where the belt conveyor 7 is relatively small, and therefore the vibration may be relatively small. In addition, if the inclination angle of the belt conveyor 7 is relatively small, the conveyed object W is unlikely to be detached from the locking portion 13 as compared with the case where the belt conveyor 7 is relatively large. Therefore, the vibration needs to be relatively large.

このような制御は、ベルトコンベア７の傾斜角度を変更するたびに、図示しない本装置の操作パネルを操作し、振動モータ２３の駆動条件を変更することによって行なうことができる。又は、ベルトコンベア７の傾斜角度を検出する角度センサを設けておき、この角度センサからの出力を用い、図示しない本装置の制御部によって振動モータ２３の駆動条件を自動的に変更するようにしてもよい。その場合には、支持部材８の着脱やベルトコンベア７の傾斜角度の設定を作業員の手作業で行なうのではなく、操作パネルからの指示でアクチュエータによってベルトコンベア７の傾斜角度を自動的に変更できるようにしておき、傾斜角度の変更に合わせて振動モータ２３の駆動条件も上述したように自動的に変更すればよい。なお、振動モータ２３の駆動条件を変えることにより搬送ベルト１１の振動状態を変更する例としては、例えば振動モータ２３の回転数を高めることによって振動の周期を短くし、より強い振動を搬送ベルト１１に発生させることや、逆に、振動モータ２３の回転数を低下させることによって振動の周期を長くし、搬送ベルト１１に発生する振動を弱めることが挙げられる。 Such control can be performed by operating an operation panel (not shown) of the present apparatus and changing the driving condition of the vibration motor 23 every time the inclination angle of the belt conveyor 7 is changed. Alternatively, an angle sensor for detecting the inclination angle of the belt conveyor 7 is provided, and the drive condition of the vibration motor 23 is automatically changed by the control unit of the apparatus (not shown) using the output from the angle sensor. Also good. In that case, the inclination angle of the belt conveyor 7 is automatically changed by an actuator according to an instruction from the operation panel, instead of manually attaching and detaching the support member 8 and setting the inclination angle of the belt conveyor 7 by an operator. The driving condition of the vibration motor 23 may be automatically changed as described above in accordance with the change of the tilt angle. As an example of changing the vibration state of the conveyor belt 11 by changing the driving condition of the vibration motor 23, for example, by increasing the number of rotations of the vibration motor 23, the period of vibration is shortened and stronger vibration is generated. Or by conversely reducing the rotational speed of the vibration motor 23 to lengthen the period of vibration and weaken the vibration generated in the conveyor belt 11.

また、ベルトコンベア７の傾斜角度に応じて、振動部材２２が搬送ベルト１１に与える振動の状態を変更するために、振動モータ２３の駆動条件は変えずに、振動部材２２を別のものに取り替えることとしてもよい。比較的円形に近い凹凸の少ない振動部材２２によれば、搬送ベルト１１に与える振動の振幅は比較的小さいが、回動軸２１から測定した振動部材２２の外周までの距離の最大差がこれより大きく、比較的いびつな凹凸の大きい振動部材２２によれば、搬送ベルト１１に与える振動の振幅はより大きくなり、搬送ベルト１１上の被搬送物Ｗにより大きな振動を与えることができる。 Further, in order to change the state of vibration applied to the conveyor belt 11 by the vibration member 22 according to the inclination angle of the belt conveyor 7, the vibration member 22 is replaced with another one without changing the driving condition of the vibration motor 23. It is good as well. According to the vibration member 22 having a relatively round shape with little unevenness, the amplitude of vibration applied to the conveyor belt 11 is relatively small, but the maximum difference in the distance from the rotating shaft 21 to the outer periphery of the vibration member 22 is larger than this. According to the large vibration member 22 with relatively irregular irregularities, the amplitude of the vibration applied to the transport belt 11 becomes larger, and a large vibration can be applied to the article W to be transported on the transport belt 11.

本実施形態の供給装置１による被搬送物Ｗとしては、前述したような形状のホタテ貝柱の冷凍品を例示したが、その他、例えば円柱状に加工した冷凍すり身製品を円盤状にカットした食品や、これらと同等の形状の物品等も対象とすることができる。本実施形態の供給装置１の対象となる被搬送品の一般的な外形としては、直径に比して高さの小さい円柱状又は半球状又はドーム状のような概ね丸い外形の固体状の塊体、又はこれに準ずるような比較的角の少ない箱型の固体状の塊体等を挙げることができ、さらに、その底面は比較的平らで載置面に安定して接することができるようなものが適している。棒のような長体状の物体や、板状の物体、粉体、粘性物等は本実施形態の供給装置１の対象からは除かれる。 As the conveyed object W by the supply device 1 of the present embodiment, the frozen product of the scallop having the shape as described above is exemplified, but in addition, for example, a food obtained by cutting a frozen surimi product processed into a column shape into a disk shape, Articles having the same shape as these can also be targeted. The general outer shape of the article to be transported that is the target of the supply device 1 of the present embodiment is a solid lump having a generally round outer shape such as a columnar shape, a hemispherical shape, or a dome shape whose height is smaller than the diameter. Body, or a box-like solid mass with relatively few corners, and the like, and the bottom surface is relatively flat and can stably contact the mounting surface. Things are suitable. A long object such as a stick, a plate-like object, powder, a viscous substance, or the like is excluded from the target of the supply device 1 of the present embodiment.

本実施形態の供給装置１では、係止部１３の構造・寸法を被搬送物Ｗの標準的な外形に応じて適当に設定し、一箇所の係止部１３には一個の被搬送物Ｗが安定して支持されるが、二個以上の被搬送物Ｗは一箇所の係止部１３に安定して載ることができず、搬送ベルト１１の振動によって不安定な被搬送物Ｗだけを落下させるようにしていた。しかしながら、このような被搬送物Ｗの落下のし易さは、被搬送物Ｗの形状や係止部１３の形状だけでなく、ベルトコンベア７の傾斜角度、振動部材２２が搬送ベルト１１に与える振動の振幅や周期等によって変わりうるものである。そこで、上述した形状に関する条件を満たす特定の被搬送物Ｗが新規に与えられた場合には、２個載りした当該被搬送物Ｗの一方を落下させ、被搬送物Ｗを確実に１個ずつ定間隔搬送して後段に送り込むため、ベルトコンベア７の傾斜角度や係止部１３の形状を被搬送物Ｗの形状に合わせて新たに設定し直すようにしてもよい。また、これらの条件を変更することが容易でないとすれば、その代わりに振動モータ２３の駆動条件を変更したり、振動部材２２を交換することで対応してもよい。すなわち、実際に被搬送物Ｗに与える振動の振幅や周期等を変えることにより、搬送しようとする物品に最も好ましい振動を与え、最も好ましい状態で不安定な被搬送物Ｗのみを落下させるように設定することもできる。 In the supply device 1 of the present embodiment, the structure and dimensions of the locking portion 13 are appropriately set according to the standard outer shape of the transported object W, and one transported object W is provided in one locking portion 13. Is supported stably, but two or more objects to be conveyed W cannot be stably placed on one locking portion 13, and only the object to be conveyed W that is unstable due to the vibration of the conveyor belt 11. I was trying to drop it. However, the ease of dropping of the transported object W is not only the shape of the transported object W and the shape of the locking portion 13, but also the inclination angle of the belt conveyor 7 and the vibration member 22 are given to the transport belt 11. It can change depending on the amplitude and period of vibration. Therefore, when a specific object to be transported W that satisfies the above-described shape condition is newly given, one of the two objects to be transported W dropped is dropped, and the objects to be transported W are surely one by one. Since it is conveyed at regular intervals and sent to the subsequent stage, the inclination angle of the belt conveyor 7 and the shape of the locking portion 13 may be newly set in accordance with the shape of the article to be conveyed W. If it is not easy to change these conditions, the driving condition of the vibration motor 23 may be changed instead, or the vibration member 22 may be replaced. That is, by changing the amplitude, period, etc. of the vibration that is actually applied to the transported object W, the most preferable vibration is applied to the article to be transported, and only the unstable transported object W is dropped in the most preferable state. It can also be set.

次に、本発明の第２実施形態を図７〜図９を参照して説明する。
第２実施形態の供給装置１は、第１実施形態の供給装置１と基本的な構成が同じであるため、第１実施形態と機能上、実質的に同等である部分には第１実施形態における部品の符号と同一の符号を付して第１実施形態の説明を援用する。以下、構成上、異なる部分のみを説明するものとする。 Next, a second embodiment of the present invention will be described with reference to FIGS.
The supply device 1 according to the second embodiment has the same basic configuration as the supply device 1 according to the first embodiment. Therefore, the first embodiment is substantially the same in function as the first embodiment. The description of the first embodiment is incorporated with the same reference numerals as those of the components. Hereinafter, only different parts in the configuration will be described.

図７〜図９に示すように、第２実施形態の供給装置５０は、振動手段２０の数が２個であり、３個であった第１実施形態よりも一つ少ない。第１実施形態で最も低い位置にあった振動手段２０の配置場所に重なるように、ベルトコンベア７の上流側の端部（高さの面では最低部）には、ベルトコンベア７と回収手段１５を囲むようにして、第１実施形態のホッパ１６よりも大型のホッパ２６が設けられている。 As shown in FIGS. 7 to 9, the supply device 50 of the second embodiment has two vibration means 20, which is one less than the first embodiment, which is three. The belt conveyor 7 and the collecting means 15 are disposed at the upstream end (the lowest part in terms of height) of the belt conveyor 7 so as to overlap the place where the vibration means 20 located at the lowest position in the first embodiment is located. A hopper 26 that is larger than the hopper 16 of the first embodiment is provided.

このホッパ２６は、図９に示すように一対の回収手段１５，１５よりも幅が大きく、図８に示すように回収手段１５及びベルトコンベア７よりも後方外側に張り出した容量の大きな容器である。このホッパ２６は、全体として矩形箱型の中空筐体であり、内壁面及び底面が中央に向いた傾斜面になっており、中央下方にある搬送ベルト１１に向けて内部が狭くなる形態となっている。従って、上部の開口２６ｃから投入された被搬送物Ｗは順次下方に移動して循環する搬送ベルト１１に供給され、ホッパ２６外に搬出される。このホッパ２６の内部に回収手段１５の案内面が連続している点は第１実施形態と同様である。このホッパ２６によれば、第１実施形態よりも多くの被搬送物Ｗを蓄えることができる。その他の作用効果については第１実施形態と同様である。 The hopper 26 is a container having a larger capacity than the pair of collecting means 15, 15 as shown in FIG. 9 and a large capacity projecting outward from the collecting means 15 and the belt conveyor 7 as shown in FIG. . The hopper 26 is a rectangular box-shaped hollow casing as a whole, and has an inner wall surface and a bottom surface that are inclined toward the center, and the inside becomes narrower toward the conveyor belt 11 below the center. ing. Accordingly, the article to be conveyed W introduced from the upper opening 26c is supplied to the conveyor belt 11 that sequentially moves downward and circulates, and is carried out of the hopper 26. The point that the guide surface of the collecting means 15 is continuous inside the hopper 26 is the same as in the first embodiment. According to this hopper 26, it is possible to store more transported objects W than in the first embodiment. Other functions and effects are the same as in the first embodiment.

以上説明した各実施形態では、供給装置１，５０の目的は後段にある重量測定装置２や重量選別装置３へ冷凍食品を搬送することであったが、もちろん搬送する物品は食品以外の物品でもよく、その種類に限定はない。また物品を供給する目的や物品が送り込まれる後段の装置や機器等の種類にも限定はない。 In each of the embodiments described above, the purpose of the supply devices 1 and 50 is to transport frozen food to the weight measuring device 2 and the weight sorting device 3 at the subsequent stage. Well, there is no limitation on the type. Further, there is no limitation on the purpose of supplying the article and the type of the subsequent apparatus or device to which the article is sent.
