- the annular grooves are mixed in different depths, and the grooves corresponding to the rollers arranged on the outer edge side of the discharge locus when discharging the conveyed object correspond to the rollers arranged on the inner edge side of the discharge locus. It is desirable that the depth is smaller than the groove to be formed.
- the annular grooves are mixed in different depths, and the grooves corresponding to the rollers arranged on the outer edge side of the discharge locus when discharging the conveyed object are arranged on the inner edge side of the discharge locus. Since the depth is shallower than the groove corresponding to the roller, the radius of the groove portion of the roller body is larger toward the outer edge side. Therefore, the amount of rotation of the roller per rotation of the roller body increases as the roller disposed on the outer edge side. In other words, for the same roller body, the groove depth is shallower on the outer edge side, and the rotation speed of the roller on the outer edge side is set to be faster than the rotation speed of the roller on the inner edge side. can do.

- pressing members (driven members) 32 and 33 are provided in the vicinity of both ends of the vertical member 8a.
- the pressing members 32 and 33 are members protruding from the vertical member 8a. The pressing members 32 and 33 move together with the base member 8 when the base member 8 swings and changes its posture.
- the two vertical members 8a having such a configuration are arranged in parallel so as to face each other. As a result of arranging the two vertical members 8a in parallel, the pressing members (driven members) 32 and 33 protrude outward.

That is, each discharge member 9 is fixed in a posture inclined by a predetermined angle with respect to the transverse member 8 b of the base member 8. Further, the roller 17 deviates from the placement surface 16 of the transverse member 8b when viewed in plan.
- the discharge member 9 includes a discharge member 9 a having two rollers 17 and a discharge member 9 b having one roller 17. That is, the support base 23a of the discharge member 9a and the support base 23b of the discharge member 9b are different in shape.
- the discharge member 9a two rollers 17 protrude from both sides of the horizontal member 8b in plan view.
- one roller 17 protrudes from one side of the horizontal member 8b.
- the number of discharge members 9 installed on each transverse member 8b may be the same, but it can be increased on the upstream side in the conveyance direction A and decreased on the downstream side. That is, the discharge member 9 on the opposite side to the discharge direction is less likely to come into contact with the transported object 25 as it goes downstream, so the discharge member 9 in that region is omitted, and the number of installations increases from the upstream side to the downstream side. It can also be reduced. For example, when the region in which each discharge member 9 is provided is viewed in plan, the number may be reduced to 4, 3, 2, 1, or so as to form a triangle.

- the belts 11a to 11d are twisted at a portion between the roller 17 and the roller driving roller 10, but transmission of power is possible. That is, when the roller driving roller 10 rotates, a rotational force is transmitted to each roller 17 via the belts 11a to 11d, and each roller 17 rotates.
- the rotational speed of each roller 17 is the slowest in the roller 17 where the belt 11a is suspended, and the fastest in the roller 17 where the belt 11d is suspended. That is, the belt 11a is suspended in the deepest groove 18a in the roller driving roller 10, and the belt 11d is suspended in the shallowest groove 18d.
- the outer peripheral length of the shallow groove is longer than the outer peripheral length of the deep groove. Therefore, the travel distance of the belt per rotation of the common roller driving roller 10 becomes longer as the belt is suspended in the shallow groove. That is, the amount of rotation of the roller per unit time increases as the roller 17 on which the belt having a long travel distance is suspended, and the rotation speed of the roller 17 is high.

- the conveyance direction is changed by drawing (discharge trajectory).
- the discharge members 9a When the belts 11a (11b to 11d) are suspended from the two rollers 17 of the discharge members 9a, the discharge members 9a receive a downward force from the two belts 11a (11b to 11d). However, as described above, each roller 17 protrudes from both sides of the transverse member 8b, and the force received from the two belts 11a (11b to 11d) is applied to both sides of the transverse member 8b and is balanced. Therefore, the discharge member 9a is pressed evenly against the lateral member 8b. That is, the support of the discharge member 9a by the lateral member 8b is stable.
- the rotational driving of the roller driving roller 10 is controlled by a control device (not shown). That is, the rotation of each roller 17 is controlled by a control device (not shown).

It is transmitted to the body 50. None of the fixed shafts 55 and 56 protruding from the cylindrical body 50 rotate. When the motor 51 is driven, the rotational force of the motor 51 is transmitted to the cylindrical body 50 via the speed reducer 52. As a result, the outer cylindrical body 50 is decelerated and rotates.

Abstract
Description
そこで本発明は、より簡単な構造であって、搬送先が先行する搬送物と後続の搬送物とで相違する場合に、先行する搬送物と後続の搬送物の間隔を詰めた状態で後続の搬送物の搬送を停止させることなく搬送することができる搬送物排出装置を提供することを課題とするものである。
例えば姿勢変更手段によって複数の排出部材の一部を降下させることによって排出部材の一部を搬送体の間に沈めた状態とする。あるいは姿勢変更手段によってベース部材の一部を上昇させて、排出部材の一部を相対的に搬送体の間に沈めた状態とする。
また姿勢変更手段によって複数の排出部材の一部を上昇させることによって排出部材の一部を搬送体の間から出たとする。あるいは姿勢変更手段によってベース部材の一部を降下させて、排出部材の一部を相対的に搬送体の間から出た状態とする。
一部の領域(搬送物の搬送方向の上流側の領域又は下流側の領域)の排出部材と他の一部の領域(搬送物の搬送方向の下流側の領域又は上流側の領域)の排出部材は、いずれもベース部材に支持されており、共通のベース部材を揺動させるだけで同時に動作させることができる。すなわち、簡単な構成で一方(一部の領域)の排出部材の上昇又は下降と、他方(他の一部の領域)の排出部材の下降又は上昇とを同時に実施することができる。
そのため、搬送物排出装置の上方を、搬送先が相違する搬送物を同時に通過させることができる。
すなわち、先行する搬送物を主搬送コンベアから排出し、後続の搬送物を主搬送コンベアから排出しない場合には、先行する搬送物は、搬送体の間から出た一部の領域(上流側)の排出部材によって搬送力が付与されて他の一部の領域(下流側)の排出部材の位置まで移動し、さらに他の一部の領域(下流側)の排出部材によって搬送力が付与されて主搬送コンベアから排出される。ここで、先行する搬送物が他の一部の領域(下流側)の排出部材によって導かれているときには、先行する搬送物は、一部の領域(上流側)の排出部材を通過しており、一部の領域(上流側)の排出部材とは接触していない。
そのため、一部の領域(上流側)の排出部材を搬送体の間に沈めても、先行する搬送物の搬送(主搬送コンベアからの排出)には影響しない。そこで本発明では、ベース部材を揺動させて、一部の領域(上流側)の排出部材を搬送体の間に沈め、後続の搬送物が一部の領域(上流側)の排出部材と接触しないようにすることができる。
よって、後続の搬送物の搬送先が先行する搬送物の搬送先と相違しても、先行する搬送物が搬送物排出装置を通過する間、後続の搬送物の搬送を停止させる必要がなく、先行する搬送物と後続の搬送物の間隔を拡げることなく後続の搬送物を搬送することができる。その結果、複数の搬送物を速やかに搬送することができる。
ベース部材の一端側と他端側が、それぞれモータと変換手段によって昇降するので、一端側を上昇させて他端側を下降させたり、一端側を下降させて他端側を上昇させることができる。すなわち、ベース部材の端部を交互に昇降させることによってベース部材を揺動させることができる。また、モータの駆動の仕方により、ベース部材の両端を同時に上昇させたり、下降させることもできる。
よって、本発明による搬送物排出装置では、簡単な構成でベース部材を揺動させることができる。
変換手段としては、カム機構、クランク機構、リンク機構,ラックアンドピニオン、ネジ等を採用することができる。
(1)上流側排出部材と下流側排出部材が共に搬送体から出た姿勢。
(2)上流側排出部材と下流側排出部材が共に搬送体の間に沈んだ姿勢。
(3)上流側排出部材が搬送体から出た状態であり、下流側排出部材が搬送体の間に沈んだ状態となる姿勢。
(4)上流側排出部材が搬送体の間に沈んだ状態であり、下流側排出部材が搬送体から出た状態となる姿勢。
図1に示す様に、コンベア装置1は、主搬送コンベア2と搬送物排出装置3とを有する。
各基台7A,7Bは、床面に載置される載置部7aと、起立する鉛直部7bとを有する。基台7A,7Bは、略長方形状の板部材を折り曲げたような構造を呈している。図4に示す様に、鉛直部7bは、載置部7aと直交しており、鉛直部7bは固定ユニット20の外側に配置されている。各鉛直部7bは、同じ構造を有しているので、以下では一方の基台7Aの鉛直部7bについて説明し、他方の基台7Bは鉛直部7bの説明は省略する。
可動ユニット21は、ベース部材8、排出部材9、コロ駆動用ローラ10(回転体)を有し、これらが一体化されたものである。
縦部材8aは、細長い板状の部材であり、長手方向に沿って複数の孔14が等間隔に設けられている。また、縦部材8aの両端付近には押圧部材(従動部材)32、33が設けられている。押圧部材32、33は、縦部材8aから突出する部材である。押圧部材32,33は、ベース部材8が揺動し、姿勢変更した際、ベース部材8と共に移動する。
以上説明したベース部材8、各排出部材9、各コロ駆動用ローラ10は一体化されており、可動ユニット21を構成している。
図3、図4に示す昇降機構12は、固定ユニット20に支持されながら、可動ユニット21の一端を個別に昇降させる機能を有するものである。昇降機構12は、2本の昇降用モータ内蔵ローラ40,41と、各昇降用モータ内蔵ローラ40,41の両端に配置されたリング76(変換手段)とを有する。
昇降用モータ内蔵ローラ40,41では、標準的な減速比の減速機52が採用されている。また昇降用モータ内蔵ローラ40,41では、ベース部材8(固定ユニット20)の姿勢を安定させる為に内部に抵抗部材が設けられている。さらに昇降用モータ内蔵ローラ40,41は、形状が特殊な蓋部材70,71を備えている。
リング76及び円形突起75は一種のカムであり、円形突起75が回転することによってベース部材8との接続部分の高さが変わる。
昇降用モータ内蔵ローラ40,41の一方だけを回転させることにより、可動ユニット21のベース部材8が揺動する。
(1)上流側排出部材と下流側排出部材が共にローラ5から上に出た姿勢(ベース部材8が水平姿勢であって排出部材が上昇した状態)。
(2)上流側排出部材と下流側排出部材が共にローラ5の間に沈んだ姿勢(ベース部材8が水平姿勢であって排出部材が降下した状態)。
(3)上流側排出部材がローラ5から上に出た状態であり、下流側排出部材がローラ5の間に沈んだ状態となる姿勢(ベース部材8が傾斜姿勢であって上流側排出部材が上昇し下流側が降下した姿勢)。
(4)上流側排出部材がローラ5の間に沈んだ状態であり、下流側排出部材がローラ5から上に出た状態となる姿勢(ベース部材8が傾斜姿勢であって上流側排出部材が降下し下流側が上昇した姿勢)。
ベース部材8が水平姿勢から傾斜姿勢に変化するとき、およびその逆の動作を行うときに、ベース部材8が揺動することとなる。
コンベア装置1の搬送方向Aの上流側及び下流側には、図示しない別の搬送コンベアが隣接配置されて、搬送物25を搬送する主搬送路15(図11)を構成している。搬送物25は、主搬送路15に沿って搬送される。搬送物排出装置3を備えたコンベア装置1は、上流側の別の搬送コンベアから搬送されてきた搬送物25をそのまま主搬送路15に沿って下流側の別の搬送コンベアへ搬送したり、主搬送路15とは異なる方向へ排出することもできる。
ベース部材8を水平姿勢であって排出部材が降下した状態とすることにより、搬送物25,26を連続的に主搬送路15に沿って搬送することができる。
ベース部材8を傾斜姿勢であって上流側排出部材が上昇し下流側が降下した姿勢とすることにより、下流側で先行する搬送物25を直進させつつ、上流側で後続の搬送物26を側方に排出するべく受け入れることができる。
ベース部材8を傾斜姿勢であって上流側排出部材が降下し下流側が上昇した姿勢とすることにより、下流側で先行する搬送物25を側方に排出しつつ、上流側で後続の搬送物26を直進させるべく受け入れることができる。
本実施形態では、ベース部材8が傾斜姿勢であって上流側排出部材が上昇し下流側が降下した姿勢とする。その結果、図11(b)の様に上流側排出部材がローラ5から上に出た状態となり、下流側排出部材がローラ5の間に沈んだ状態となる。
そして続いて昇降機構12を動作させ、ベース部材8を揺動させて図12の様にベース部材8が水平姿勢であって排出部材9(コロ17)が上昇した状態に姿勢変更する。その結果、図12の様に、上流側排出部材と下流側排出部材が共にローラ5から上に出た姿勢となる。
そのため図12に示す様に、先行する搬送物25は、回転するコロ17によって傾斜方向(排出先)に導かれる。さらに搬送物25は、図13に示す様に、搬送物排出装置3の上流側の排出部材9(コロ17)から下流側の排出部材9(コロ17)に移動する。
また、先行する搬送物25に続いて主搬送コンベア2上には後続の搬送物26が搬送されてくる。後続の搬送物26の搬送先が、主搬送コンベア2に沿った直進方向(主搬送路15)である場合には、図示しない制御装置は上流側の昇降用モータ内蔵ローラ40を駆動させ、ベース部材8を揺動して図13の様にベース部材8を姿勢変更する。すなわちベース部材8が傾斜姿勢であって上流側排出部材が降下し下流側が上昇した姿勢に姿勢変更する。その結果、上流側排出部材がローラ5の間に沈んだ状態となり、下流側排出部材がローラ5から上に出た状態となる。
こうして上流側の排出部材9(コロ17)を搬送面4よりも下方に没入させる(図13(b))。このとき、下流側の排出部材9(コロ17)は、搬送面4よりも上に突出しているため、先行する搬送物25の側方への排出は継続して行われ、上流側の排出部材9(コロ17)は、搬送面4よりも下に没入しているので、後続の搬送物26はローラ5によって主搬送コンベア2に沿って搬送される。
ここで本実施形態では、ベース部材8が水平姿勢であって排出部材が降下した状態に変化させる。その結果、上流側排出部材と下流側排出部材が共に搬送体の間に沈んだ姿勢となる。
具体的には、図示しない制御装置は、下流側の昇降用モータ内蔵ローラ41を駆動し、ベース部8を揺動して下流側の排出部材9(コロ17)を搬送面4より下に没入させる。そのため、後続の搬送物26は、ローラ5によって主搬送コンベア2に沿って下流側へ搬送される。
そして、搬送物26が下流側の排出部材9(コロ17)の上方を通過すると、図示しない制御装置は、下流側の排出部材9(コロ17)を搬送面4よりも上に上昇させる。
以下、上述した同様の動作が繰り返し行われる。
しかしながら、排出部材9の搬送体(ローラ5)からの出没は、相対的なものであるから、搬送体(ローラ5)側を姿勢変更させて排出部材9を搬送体(ローラ5)からの出没させてもよい。この場合には、主搬送コンベア2側をベース部材とし、主搬送コンベア2に昇降機構12を取り付けて主搬送コンベア2を揺動させることとなる。
これに代わって、ベース部材を昇降させる機構と、揺動させる機構を別個に設けてもよい。
例えばベース部材をピン等を中心として揺動する様に構成し、ベース部材揺動用モータでベース部材を揺動させる。
またベース部材をガイドに沿って昇降可能とし、昇降用のモータを別途設けてベース部材を昇降させる。
