It relates to a transport method.

コンバイナは、特許文献2に開示されているように、充填装置や、ラベラ装置や、検査装置などの壜や缶などの縦長の容器を扱う装置の上流に設置し、上流側から複数列のコンベヤによって前後左右を互いに接触しながら供給される容器を、間隔をあけて1列に並べて下流側に送出する搬送装置である。   As disclosed in Patent Document 2, the combiner is installed upstream of a device for handling a vertical container such as a jar or can such as a filling device, a labeler device, or an inspection device, and a plurality of rows of conveyors from the upstream side. Is a conveying device that arranges the containers supplied while contacting the front, back, left and right with each other in a line at intervals and sends them to the downstream side.

代表的な従来のコンバイナの構成を図5(特許文献1の第4図に相当する)及び図6によって説明する。
図5はその従来のコンバイナの平面図、図6は図5におけるII矢視図である。
両図において、1は駆動モータ6で駆動され、搬送速度が同じ複数列(図では4列)のスラットチェンコンベヤ(以下単にコンベヤと呼ぶ)で成る入口コンベヤ、2は駆動モータ7で駆動され、搬送速度がそれぞれ異なる複数列(図では6列)のコンベヤで成る速度差コンベヤ、また、3は駆動モータ8で駆動される1列のコンベヤの出口コンベヤである。これらのコンベヤは図6に示すように何れも水平に設置されている。
速度差コンベヤ2は入口コンベヤ1の隣に、出口コンベヤ3は速度差コンベヤ2の隣に、それぞれの一部を相手のコンベヤと搬送方向に併走させている。
速度差コンベヤ2の各列の速度は、スプロケットトレイン9によって増速され、入口コンベヤ1から出口コンベヤ3の方向に順次大きくなっていて、入口コンベヤ1の速度より大きく、出口コンベヤ3より小さくなっている。図5の右側に示す矢印は、コンベヤ速度の大きさを示している。

The structure of a typical conventional combiner will be described with reference to FIG. 5 (corresponding to FIG. 4 of Patent Document 1) and FIG.
FIG. 5 is a plan view of the conventional combiner, and FIG. 6 is a view taken along arrow II in FIG.
In both figures, 1 is driven by a drive motor 6, an entrance conveyor formed of slat chain conveyors (hereinafter simply referred to as conveyors) of a plurality of rows (four rows in the figure) having the same conveying speed, 2 is driven by a drive motor 7, A speed difference conveyor composed of a plurality of rows (six rows in the figure) of conveyors having different conveying speeds, and 3 is an outlet conveyor of a row of conveyors driven by a drive motor 8. All of these conveyors are installed horizontally as shown in FIG.
The speed difference conveyor 2 is next to the entrance conveyor 1, and the outlet conveyor 3 is next to the speed difference conveyor 2.
The speed of each row of the speed difference conveyor 2 is increased by the sprocket train 9 and gradually increases in the direction from the entrance conveyor 1 to the exit conveyor 3 and is larger than the speed of the entrance conveyor 1 and smaller than the exit conveyor 3. Yes. The arrows shown on the right side of FIG. 5 indicate the size of the conveyor speed.
Reference numerals 4 and 5 denote main guides and sub-guides provided at appropriate heights on the upper side of the conveyor and on both sides in the container transport direction, both of which are transported upstream of the inlet conveyor 1 and downstream of the outlet conveyor 3. Parallel to the direction, it is obliquely crossed in the transport direction between them, and the distance between the two is narrower on the downstream side. 10 is a container, and the figure shows the case of a can.

上記構成の従来のコンバイナの作用を説明する。
入口コンベヤ1から前後及び左右を互いに接触させて複数列で供給された容器10は、下流側に進んで鋭角で主ガイド4に当接し、主ガイド4の側面から受ける反力によって速度差コンベヤ2の方向に移動し、更に搬送速度の大きいコンベヤの方向に移動して速度を増す。このように速度を増した容器10は互いの間隔を広げて出口コンベヤ3では1列となって下流側に送出される。なお、副ガイド5は容器10が反対側に自由に広がるのを規制して、流れに淀みができたり容器10が転倒するのを防いでいる。
The operation of the conventional combiner having the above configuration will be described.
The containers 10 supplied in a plurality of rows from the entrance conveyor 1 in front and rear and left and right are advancing downstream and come into contact with the main guide 4 at an acute angle, and by the reaction force received from the side surface of the main guide 4, the speed difference conveyor 2 In the direction of the conveyor, and further in the direction of the conveyor having a higher conveying speed, the speed is increased. The containers 10 whose speeds are increased in this way are widened with each other, and are sent out to the downstream side in the outlet conveyor 3 in one row. The sub-guide 5 restricts the container 10 from freely spreading to the opposite side to prevent stagnation in the flow or the container 10 from falling down.

コンバイナの下流に配設される充填装置や、ラベラ装置や、検査装置の能力向上に伴い、コンバイナもこれに対応して能力の向上が必要となっており、容器の搬送能力が大きく、機長が短く設置スペースの小さい装置の提供が望まれている。
しかし、上述の従来のコンバイナでは、搬送速度を大きくすると、容器がガイドと当接するときに受ける衝撃力によって、また搬送速度の大きいコンベヤに乗移るときにコンベヤから受ける摩擦力によって容器が転倒し易く、あるいは主ガイドと副ガイドの間に容器がブリッジ状に詰まり(ジャミング)を生じて運転を妨げるという問題がある。
本発明は容器の転倒やジャミングを防止すると共に、容器が隣の大きな搬送速度のコンベヤに移ったときの容器の加速力を増して、上述の問題点を解決したコンバイナ及びコンバイナによる容器の搬送方法の提供を目的としている。
As the capacity of the filling equipment, labeler equipment, and inspection equipment installed downstream of the combiner is improved, the capacity of the combiner needs to be improved accordingly. It is desired to provide a device having a short installation space.
However, in the above-described conventional combiner, when the conveyance speed is increased, the container easily falls down due to the impact force received when the container comes into contact with the guide and due to the frictional force received from the conveyor when moving to the conveyor having a high conveyance speed. Alternatively, there is a problem that the container is jammed in a bridge shape (jamming) between the main guide and the sub guide, thereby hindering operation.
The present invention prevents a container from overturning or jamming and increases the accelerating force of the container when the container is moved to the next conveyor having a large conveying speed to solve the above-described problems, and a container conveying method using the combiner The purpose is to provide.

上記問題点に対し、本発明は以下の各手段により課題の解決を図る。
(1)第1の手段のコンバイナは、同じ搬送速度の複数列のスラットコンベヤで成る入口コンベヤと、この入口コンベヤに一部が併走するように隣接し、搬送速度が順次大きくなるとともに前記入口コンベヤのスラットコンベヤよりも大きい複数列のスラットコンベヤで成る速度差コンベヤと、この速度差コンベヤに一部が併走するように隣接する搬送速度が速度差コンベヤより大きい1列のスラットコンベヤで成る出口コンベヤと、これらのコンベヤの上側に配設され搬送方向に斜めに走り入口コンベヤの巾から出口コンベヤの巾に狭まる2本のガイドとより構成されるコンバイナであって、速度差コンベヤの上流側端から下流側端までの範囲の前記3つのコンベヤの傾斜角度αを、水平面に対して前下がりにコンベヤの摩擦角より小さい角度で傾斜させたことを特徴とする。
With respect to the above problems, the present invention aims to solve the problems by the following means.
(1) a combiner of the first means, the inlet conveyor and inlet conveyor comprising at slat conveyor a plurality of rows of the same transport speed, together with the adjacent such portion is adjacent parallel to the inlet conveyor, the conveying speed is increased sequentially A speed difference conveyor composed of a plurality of rows of slat conveyors larger than the slat conveyor of the present invention; The combiner is composed of two guides disposed on the upper side of these conveyors and running obliquely in the conveying direction and narrowing from the width of the entrance conveyor to the width of the exit conveyor, and is downstream from the upstream end of the speed difference conveyor. the inclination angle α of said three conveyors ranging side edge, the friction angle is smaller than the conveyor forwardly and downwardly relative to the horizontal plane Wherein the tilted in degrees.

前記コンバイナを形成する3つのコンベヤを、速度差コンベヤの上流側端から下流側端までの範囲で搬送方向上流側から下流側へ向けて下向き傾斜させることにより、傾斜によって生ずる容器にはたらく重力の搬送方向への分力と、コンベアから受ける摩擦力によって、容器を移送先のコンベアの搬送速度まで加速させることが可能となる。   Gravity transport acting on containers caused by tilting by inclining the three conveyors forming the combiner downward from the upstream end to the downstream end in the transport direction in the range from the upstream end to the downstream end of the speed difference conveyor. The container can be accelerated to the transport speed of the transfer destination conveyor by the component force in the direction and the frictional force received from the conveyor.

(2)搬送する容器の直径をd、容器の重心の高さをhとしたとき、前記3つのコンベヤの傾斜角度αを
α<arctan(d/2h)
の範囲で傾斜させることを特徴とする。
(2) When the diameter of the container to be conveyed is d and the height of the center of gravity of the container is h, the inclination angle α of the three conveyors is α <arctan (d / 2h)
It is made to incline in the range of.

傾斜角度αをα<arctan(d/h)の範囲とすることで、容器の重心位置が、コンベアとの接触面であり搬送方向先端位置よりも搬送方向上流側に位置するようになるため、容器が搬送方向側に転倒しなくなる。   By setting the inclination angle α in the range of α <arctan (d / h), the center of gravity of the container is a contact surface with the conveyor and is located on the upstream side in the transport direction with respect to the front end position in the transport direction. The container will not fall over in the transport direction.

(3)前記入口コンベヤと前記速度差コンベヤ中の最低搬送速度のコンベヤとの速度差及び前記傾斜角度αを、搬送する容器が入口コンベヤ上から速度差コンベヤ上に移動する際に搬送上流側に転倒しない組み合わせに設定することを特徴とする。
このことにより、容器が入口コンベヤから速度差コンベヤに移動した際に、容器の転倒を防止しつつ移動先の速度差コンベアの搬送速度まで加速させることが可能となる。
(3) The speed difference between the entrance conveyor and the conveyor with the lowest transport speed in the speed difference conveyor and the inclination angle α are transferred to the upstream side when the container to be transported moves from the entrance conveyor to the speed difference conveyor. It is set to the combination which does not fall.
As a result, when the container moves from the entrance conveyor to the speed difference conveyor, it is possible to accelerate to the transport speed of the destination speed difference conveyor while preventing the container from overturning.

(4)前記速度差コンベヤ中の最高搬送速度のコンベヤと前記出口コンベヤとの速度差及び前記傾斜角度αを、搬送する容器が速度差コンベヤ上から出口コンベヤ上に移動する際に搬送上流側に転倒しない組み合わせに設定することを特徴とする。
このことにより、容器が速度差コンベヤから出口コンベヤに移動した際に、容器の転倒を防止しつつ移動先の出口コンベヤの搬送速度まで加速させることが可能となる。
(4) The speed difference between the conveyor at the highest transport speed in the speed difference conveyor and the outlet conveyor and the inclination angle α are set to the upstream side when the container to be transported moves from the speed difference conveyor onto the outlet conveyor. It is set to the combination which does not fall.
As a result, when the container moves from the speed difference conveyor to the outlet conveyor, the container can be accelerated to the conveyance speed of the destination outlet conveyor while preventing the container from falling.

(5)第5の手段のコンバイナによる容器の搬送方法は、同じ搬送速度の複数列のスラットコンベヤで成る入口コンベヤと、この入口コンベヤに一部が併走するように隣接し、搬送速度が順次大きくなるとともに前記入口コンベヤのスラットコンベヤよりも大きい複数列のスラットコンベヤで成る速度差コンベヤと、この速度差コンベヤに一部が併走するように隣接する搬送速度が速度差コンベヤより大きい1列のスラットコンベヤで成る出口コンベヤと、これらのコンベヤの上側に配設され搬送方向に斜めに走り入口コンベヤの巾から出口コンベヤの巾に狭まる2本のガイドとより構成されるコンバイナを用いて、3つのコンベヤ上に載置されて走行する容器をガイドによって順次速度の大きいコンベヤに移送させて増速させ、複数列で受け入れた容器を1列に整列させて排出するコンバイナによる容器の搬送方法において、速度差コンベヤの上流側端から下流側端までの範囲の前記3つのコンベヤの傾斜角度αを、水平方向に対して搬送方向に前下りにコンベヤの摩擦角より小さい傾斜角度で傾斜させ、傾斜によって生ずる容器にはたらく重力の搬送方向への分力とコンベヤから受ける摩擦力とによって、容器を移送先のコンベヤの搬送速度まで加速することを特徴とする。 (5) The container transport method using the combiner of the fifth means is such that the entrance conveyor composed of a plurality of rows of slat conveyors of the same transport speed is adjacent to the entrance conveyor so that a part of the conveyor is parallel, and the transport speed is increased gradually. A speed difference conveyor comprising a plurality of rows of slat conveyors larger than the entrance conveyor slat conveyor , and a row of slat conveyors adjacent to the speed difference conveyor so that a part of the speed difference conveyor is parallel to the speed difference conveyor. The three conveyors are composed of an outlet conveyor composed of two guides disposed on the upper side of these conveyors and running diagonally in the conveying direction and narrowing from the width of the inlet conveyor to the width of the outlet conveyor. Containers that are placed on top are moved by a guide to a high-speed conveyor in order to increase the speed. In method of transporting containers by the combiner to discharge align the only put containers in a row, the inclination angle α of said three conveyors ranging from the upstream end of the speed difference conveyor to the downstream end, with respect to the horizontal direction The container is transported to the destination conveyor by the component force in the transport direction of gravity acting on the container caused by the tilt and the frictional force received from the conveyor. It is characterized by accelerating to speed.

以上記載のごとく本発明によれば、コンバイナの流れ方向への前下がりの傾斜をつけることにより、コンベア自体の高摩擦係数化に伴う容器の転倒やジャミングといったリスクを増大させることなく、同傾斜によって生ずる容器にはたらく重力の搬送方向への分力と、コンベアから受ける摩擦力によって、容器を移送先のコンベアの搬送速度まで加速させることが可能となり、従来と同等の機長で、高速化、高能力化を実現できるとともに、従来と同等の能力をコンバイナの機長を短縮したもので達成可能となり、省スペース化を図ることができる。   As described above, according to the present invention, by adding a forward and downward inclination in the flow direction of the combiner, without increasing the risk of the container falling or jamming due to the higher friction coefficient of the conveyor itself, It is possible to accelerate the container to the transfer speed of the transfer destination conveyor by the force of gravity acting on the resulting container in the transfer direction and the frictional force received from the conveyor. In addition, it is possible to achieve the same capacity as before by reducing the length of the combiner, thereby saving space.

以下、図面を参照して本発明の好適な実施例を例示的に詳しく説明する。但しこの実施例に記載されている構成部品の寸法、材質、形状、その相対的配置等は特に特定的な記載がない限りは、この発明の範囲をそれに限定する趣旨ではなく、単なる説明例に過ぎない。   Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the drawings. However, the dimensions, materials, shapes, relative arrangements, and the like of the components described in this embodiment are not intended to limit the scope of the present invention unless otherwise specified, but are merely illustrative examples. Not too much.

本発明のコンバイナの実施の形態を図1〜図5によって説明する。図1はコンバイナの正面図、図2は容器に作用する外力と反力の関係を示す説明図、図3は容器を加速する搬送方向の力と、コンベアの傾斜角の関係を示すダイヤグラム、図4は容器が1つのコンベヤから隣接する搬送速度の速いコンベヤに移動する状態を示す部分平面図である。この実施の形態のコンバイナは前述の従来例と同様の構成であり、平面図は従来例の図5とほぼ同様なので、図5を流用することとし、本実施の形態を表す場合は従来例の番号に50を加えて表すこととする。   An embodiment of a combiner of the present invention will be described with reference to FIGS. FIG. 1 is a front view of a combiner, FIG. 2 is an explanatory diagram showing the relationship between external force and reaction force acting on the container, FIG. 3 is a diagram showing the relationship between the conveying direction force for accelerating the container and the inclination angle of the conveyor, and FIG. 4 is a partial plan view showing a state in which containers move from one conveyor to an adjacent conveyor having a high conveyance speed. The combiner of this embodiment has the same configuration as the above-described conventional example, and the plan view is almost the same as FIG. 5 of the conventional example. Therefore, FIG. 5 is used, and this embodiment is represented by the conventional example. The number is represented by adding 50.

このコンバイナは、複数列の同じ搬送速度のコンベヤ(スラットチエンコンベヤ)で成る入口コンベヤ51と、この入口コンベヤ51に隣接して一部が併走する順次に搬送速度を増す複数列のコンベヤで成る速度差コンベヤ52と、この速度差コンベヤ52に隣接し一部が併走する搬送速度が最大の1列のコンベヤの出口コンベヤ53と、これらのコンベヤの上部を斜めに走り、下流側が狭くなる主ガイド54及び副ガイド55で構成されたコンバイナであって、速度差コンベヤ52の上流側端Aから下流側端Bまでの間にあるこれらの3つのコンベヤを、水平面に対して下流側が下がる摩擦角θより小さい角度αの勾配をつける。従って入口コンベヤ51の下流側の一部、及び出口コンベヤ53の上流側の一部の併走部分も傾斜することになる。
また、入口コンベヤ51、速度差コンベヤ52、及び出口コンベヤ53の容器10に対する摩擦角θは極力小さくする。なお、図1に示す速度差コンベヤ52の駆動モータ57は直交軸型駆動モータをコンベヤフレームに取付けた場合を示してあり、その他の駆動モータや変速用のスプロケットトレイン等は図示を省略してある。
This combiner is composed of an inlet conveyor 51 composed of a plurality of rows of conveyors (slattyen conveyors) having the same conveying speed, and a speed composed of a plurality of rows of conveyors, which are adjacent to the inlet conveyor 51 and sequentially increase the conveying speed. The difference conveyor 52, the exit conveyor 53 of the one-line conveyor having a maximum conveying speed adjacent to the speed difference conveyor 52, and the main guide 54 that runs obliquely above the conveyor and narrows the downstream side. And these three conveyors between the upstream end A and the downstream end B of the speed difference conveyor 52 from the friction angle θ that the downstream side is lowered with respect to the horizontal plane. A small angle α is applied. Therefore, a part of the downstream side of the inlet conveyor 51 and a part of the side of the upstream side of the outlet conveyor 53 are also inclined.
Further, the friction angle θ of the inlet conveyor 51, the speed difference conveyor 52, and the outlet conveyor 53 with respect to the container 10 is made as small as possible. The drive motor 57 of the speed difference conveyor 52 shown in FIG. 1 shows a case where an orthogonal axis type drive motor is attached to the conveyor frame, and other drive motors, sprocket trains for shifting, etc. are not shown. .

ここで、前記入口コンベヤ51を形成する各コンベアの搬送速度をv51、前記速度差コンベヤ52を形成するコンベヤの搬送速度を前記入口コンベヤと隣接するコンベヤから順にv521、v522、v523、v524、v525、v526、前記出口コンベヤの搬送速度をv53とすると、
51<v521<v522<v523<v524<v525<v526<v53
が成立する。
なお、各コンベアの搬送速度の関係は、これに限定するものではないが、後述する理由により、本実施例のように容器10の移動に従って順次搬送速度を増すようにするとよい。
Here, the conveyance speed of each conveyor forming the entrance conveyor 51 is v 51 , and the conveyance speed of the conveyor forming the speed difference conveyor 52 is v 521 , v 522 , v 523 , sequentially from the conveyor adjacent to the entrance conveyor. When v 524 , v 525 , v 526 , and the conveyance speed of the exit conveyor is v 53 ,
v 51 <v 521 <v 522 <v 523 <v 524 <v 525 <v 526 <v 53
Is established.
In addition, although the relationship of the conveyance speed of each conveyor is not limited to this, it is good to increase a conveyance speed sequentially according to the movement of the container 10 like a present Example for the reason mentioned later.

また、前記速度差コンベヤを形成する1つのスラットコンベヤと該スラットコンベヤと隣接する搬送速度の速いスラットコンベヤとの速度差及び前記傾斜角度αは、前記容器が速度差コンベヤを形成する1つのスラットコンベヤ上から隣接する搬送速度の速いスラットコンベヤ上に移動する際に搬送上流側に転倒しない組み合わせに設定する。
容器10が缶のようにコンベヤとの相対摩擦係数が低く容器搬送上安定している容器である場合には、例えば速度0のコンベヤから隣接する速度100m/minという非常に高速のコンベヤに移動する際にも、その極端な速度差を容器はガイドに沿いながら自転することでエネルギーを開放しながら徐々に高速側のコンベヤの速度に加速していく。従って、容器の移動に従って順次搬送速度を増すようにすると、その速度差の大きさが原因によって容器が転倒しにくい。
In addition, the speed difference between the one slat conveyor forming the speed difference conveyor and the slat conveyor having a high conveying speed adjacent to the slat conveyor and the inclination angle α are determined by the one slat conveyor in which the container forms the speed difference conveyor. When moving from the top to the adjacent slat conveyor with a high transport speed, the combination is set so that it does not fall to the upstream side of the transport.
When the container 10 is a container that has a low relative friction coefficient with the conveyor and is stable in terms of container conveyance, such as a can, the container 10 moves from a conveyor having a speed of 0 to a very high speed conveyor having a speed of 100 m / min. Even when the container rotates along the guide, the container speeds up to the speed of the high-speed conveyor while releasing energy. Therefore, if the conveying speed is increased sequentially as the container moves, the container is unlikely to fall down due to the magnitude of the speed difference.

上記構成のコンバイナの作用について説明する。
容器10が入口コンベヤ51の水平部分に載って移動しているときには、等速運動なので、図2(a)に示すように、容器に掛かる外力は重心に掛かる下向きの重力Wとコンベヤ51から上向きに掛かる垂直力の反力Wのみで、互いに打消して合力は0となり、搬送方向の摩擦力(反力)は発生しない。
The operation of the combiner having the above configuration will be described.
When the container 10 is moving on the horizontal portion of the entrance conveyor 51, it moves at a constant speed. Therefore, as shown in FIG. 2A, the external force applied to the container is upward from the conveyor 51 and the downward gravity W applied to the center of gravity. Only the reaction force W of the vertical force applied to each other cancels each other and the resultant force becomes 0, and no friction force (reaction force) in the transport direction is generated.

容器10が入口コンベヤ51の傾斜部に進むと、図2(b)に示すように、重力Wはコンベヤ51の搬送方向を向く分力Wsinαと、直角下方に向く分力Wcosαの2つの分力を持つ力として働き、コンベヤ51からこれらに対する反力として反搬送方向に向く摩擦反力Wsinαと搬送方向に直角上方に向く直角反力Wcosαを受けて合力は0となる。この摩擦反力Wsinαは容器10の底部が摩擦力の方向に回転する回転モーメントを生じるが、コンベヤ51は直角反力Wcosαの作用線の位置を容器10の底面の範囲内で移動させて抵抗モーメントを発生して回転モーメントを打消して容器10は回転せずに静止している。
なお、角度αは角度β=arctan(d/2h)より小さいものとする。(hは重心Wの高さ、dは容器10の直径)
When the container 10 advances to the inclined portion of the entrance conveyor 51, as shown in FIG. 2 (b), the gravity W has two component forces, namely, a component force Wsinα that faces the conveying direction of the conveyor 51 and a component force Wcosα that faces downward at a right angle. As a reaction force against these from the conveyor 51, the resultant reaction force becomes zero upon receiving a friction reaction force Wsinα directed in the anti-conveyance direction and a right-angle reaction force Wcosα directed perpendicularly upward in the conveyance direction. The friction reaction force Wsinα generates a rotational moment in which the bottom of the container 10 rotates in the direction of the frictional force, but the conveyor 51 moves the position of the line of action of the right-angle reaction force Wcosα within the range of the bottom surface of the container 10 to generate a resistance moment. The container 10 is stationary without rotating by canceling the rotational moment.
Note that the angle α is smaller than the angle β = arctan (d / 2h). (H is the height of the center of gravity W, d is the diameter of the container 10)

容器10がある搬送速度のコンベヤ21から隣接する搬送速度の大きいコンベヤ22に移動する時には、図4に示すように、容器10は容器全体がコンベヤ21上に位置する状態aから、容器の一部がコンベヤ21上であり残りの一部がコンベヤ22上に位置する状態bを経て、容器全体がコンベヤ22上に位置する状態cへと移動していく。状態aから状態cへの移動の過程で容器10にはたらく力は以下のように変化する。   When the container 10 moves from a conveyor 21 having a certain conveying speed to an adjacent conveyor 22 having a large conveying speed, the container 10 is moved from a state a in which the entire container is positioned on the conveyor 21, as shown in FIG. Is moved to a state c where the entire container is located on the conveyor 22 through the state b where the remaining part is located on the conveyor 22 and the remaining part is located on the conveyor 22. The force acting on the container 10 in the process of moving from the state a to the state c changes as follows.

容器10がある搬送速度のコンベヤ(以下低速コンベヤと呼ぶ)から隣の搬送速度の大きいコンベヤ(以下高速コンベヤと呼ぶ)に乗移る時には、容器10はその底面に高速コンベヤから搬送方向に向く摩擦力を、低速コンベヤからはこれを打消す逆向きの摩擦力を受け、容器10の乗移りが進むに連れて逆向きの摩擦力は消滅し、搬送方向に向く摩擦力は増大して最大値のWcosαtanθに達する。最終の運動のみに着目すると、図2(c)に示すように、この最大摩擦力Wcosαtanθと重力の搬送方向の分力Wsinαとの合力が容器10を高速コンベヤの搬送速度まで加速する搬送方向の力(N)として作用する。この合力のうち搬送方向の分力Wsinαは質量力であって容器10の重心を通るので容器10の回転には関らず、容器10の底面に掛かる最大摩擦力Wcosαtanθのみが容器の底部を搬送方向に回転させるモーメントを発生する。コンベヤの直角反力Wcosαは着力点を移動させてこれを打消すが、不足する場合には容器10は転倒することになる。   When the container 10 is transferred from a conveyor having a certain conveying speed (hereinafter referred to as a low speed conveyor) to the adjacent conveyor having a large conveying speed (hereinafter referred to as a high speed conveyor), the container 10 has a frictional force directed toward the conveying direction from the high speed conveyor to the bottom surface thereof. The low-speed conveyor receives a reverse friction force that cancels this, and as the transfer of the container 10 proceeds, the reverse friction force disappears, and the friction force toward the conveyance direction increases to a maximum value. Wcos α tan θ is reached. Focusing only on the final motion, as shown in FIG. 2 (c), the resultant force of the maximum frictional force Wcos α tan θ and the component force W sin α in the gravity conveying direction accelerates the container 10 to the conveying speed of the high-speed conveyor. Acts as a force (N). Of this resultant force, the component force Wsinα in the conveyance direction is a mass force and passes through the center of gravity of the container 10, so that only the maximum frictional force Wcosαtanθ applied to the bottom surface of the container 10 is conveyed through the bottom of the container regardless of the rotation of the container 10. Generate moment to rotate in the direction. The conveyor's right-angle reaction force Wcosα moves the applied point and cancels it, but if it is insufficient, the container 10 will fall.

図3は、摩擦係数tanθを0.2(θ=11.3°)、容器にはたらく重力Wを3.43N(容器重量0.35kg)としたときの、傾斜角α(0〜11.3°)に対する容器10を加速する加速力(搬送力)の大きさの関係を示してある。   FIG. 3 shows an inclination angle α (0 to 11.3) when the friction coefficient tan θ is 0.2 (θ = 11.3 °) and the gravity W acting on the container is 3.43 N (container weight 0.35 kg). The relationship of the magnitude of the acceleration force (conveying force) for accelerating the container 10 with respect to (°) is shown.

以上述べたように、容器10が高速コンベヤの方に方向を変えて移動したり、高速の搬送速度に増速したりする加速運動をする場合には、コンベヤから最大値の摩擦力Wcosαtanθを受け、この摩擦力は容器10を底部が摩擦力の方向に回る回転モーメントを生じて転倒の原因となるので、本発明のコンバイナのコンベヤの摩擦角θ(摩擦係数tanθ)は極力小さいものとする。この摩擦角θの低減は複数の容器10が主ガイドと副ガイドの間に詰まるブリッジ現象を防止するのにも役立つ。容器10を高速コンベヤの搬送速度まで増速する力として、コンベヤから受ける搬送方向に向いた最大値摩擦力(表面力)と、コンベヤを傾斜させて生ずる同方向を向く重力の搬送方向の分力(質量力)とを用いる。この分力は容器10を回転させるモーメントを伴わない利点がある。この容器10の搬送力は、図3に示すようにコンベヤの傾斜角αをコンベヤの摩擦角θに近づければ最大摩擦力の2倍近くとすることが出来、容器10を高速コンベヤの搬送速度まで加速する時間と距離を短縮することができ、コンバイナの機長の短縮に寄与することができる。   As described above, when the container 10 moves in the direction of the high-speed conveyor and moves at an increased speed, the container 10 receives the maximum frictional force Wcosαtanθ from the conveyor. Since this frictional force causes a rotational moment in which the bottom of the container 10 turns in the direction of the frictional force, it causes a fall, so the friction angle θ (friction coefficient tanθ) of the conveyor of the combiner of the present invention is assumed to be as small as possible. The reduction of the friction angle θ is also useful for preventing a bridge phenomenon in which a plurality of containers 10 are clogged between the main guide and the sub guide. The maximum frictional force (surface force) in the conveying direction received from the conveyor and the force in the gravity conveying direction in the same direction generated by inclining the conveyor as the force to increase the container 10 to the conveying speed of the high-speed conveyor (Mass force) is used. This component force has the advantage of not involving a moment for rotating the container 10. As shown in FIG. 3, the conveying force of the container 10 can be nearly twice the maximum frictional force if the conveyor inclination angle α is brought close to the friction angle θ of the conveyor. The acceleration time and distance can be shortened, which can contribute to the shortening of the combiner's captain.
