Description

【０００１】
【発明の属する技術分野】
本発明は、生鳥篭蓋取り外し装置に関するものである。
【０００２】
【従来の技術】
養鶏場から食鳥処理工場への生鳥の運搬に際して、生鳥を入れる生鳥篭が使用されている。
図１〜図７に示すように、生鳥篭１００は一般に、格子構造の側壁と底壁とを有すると共に上端が開放された平面視略長方形の倒置四角錐台形状の篭本体１０１と、篭本体１０１の開放された上端に係止される格子構造の蓋１０２とを備えている。
篭本体１０１の上端に狭幅の外フランジ１０１ａが形成されている。外フランジ１０１ａの外縁は下方へ屈曲している。
篭本体１０１の長辺側側壁外面上部に、側壁の延在方向に互いに間隔を隔てて、上下に延在する２対のリブ１０１ｂが形成されている。多段に積み重ねられた状態で食鳥処理工場へ到着した生鳥篭１００を、積み降し装置を用いて最下段の生鳥篭１００から順次生鳥処理ラインの搬送コンベア上に積み降ろす際に、積み降ろされる生鳥篭の直上に位置する生鳥篭のリブ１００ｂ下端に積み下ろし装置の爪が係合して、当該直上の生鳥篭と更に上層の生鳥篭とを保持する。
蓋１０２の外周縁１０２ａは下方へ屈曲している。蓋１０２の長辺側外周縁の下端から、前記長辺の延在方向に互いに間隔を隔てて一対の係止爪１０２ｂが延びている。係止爪１０２ｂが篭本体１０１の外フランジ１０１ａの外縁下端に係合した状態で、蓋１０２は篭本体１０１の上端に係止されている。引き戸１０２ｃにより開閉可能な開口１０２ｄが蓋１０２に形成されている。
【０００３】
【発明が解決しようとする課題】
食鳥処理工場においては、従来、生鳥篭１００が搬送コンベアにより食鳥処理装置の近傍まで搬送されると、作業員が引き戸１０２ｃを引いて開口１０２ｄを開き、生鳥篭１００から開口１０２ｄを介して生鳥を一羽ずつ取り出し、食鳥処理装置のハンガーに掛けていた。この結果、生鳥篭１００から生鳥を取り出す際に生鳥が開口１０２ｄの縁と干渉して損傷する事故が多発していた。また使用済みの生鳥篭１００を蓋１０２を取り付けたまま洗浄していたので、生鳥篭内部の汚れを十分に除去できかった。
本発明は上記問題に鑑みてなされたものであり、食鳥処理工場の搬送コンベアに載置された生鳥篭から蓋を自動的に取り外す装置を提供することを目的とする。
【０００４】
【課題を解決するための手段】
上記課題を解決するために、本発明においては、生鳥篭が載置されるコンベアと、コンベアの両側に配設され、内側走行部がコンベアと同一方向に走行すると共にコンベア上に載置された生鳥篭の対峙する一対の側壁に当接する一対の第１無端チェーンと、コンベアの両側に且つ第１無端チェーンの上方に配設され、内側走行部がコンベアと同一方向に走行しつつコンベアに対して上方へ相対移動すると共にコンベアの側方且つ離隔方向へ往復移動する一対の第２無端チェーンと、互いに微少隙間を隔てて第２無端チェーンに取り付けられ、第２無端チェーンの内側走行部からコンベア中心方向へ突出し、生鳥篭の蓋に形成された係止爪に係合する複数の爪とを備えることを特徴とする生鳥篭蓋取り外し装置を提供する。
第２無端チェーンの内側走行部がコンベアと同一方向に走行しつつコンベアに対して上方へ相対移動することにより、第２無端チェーンの内側走行部からコンベア中心方向へ突出する爪が、生鳥篭の蓋に形成された係止爪に下方から係合し、生鳥篭をコンベアから持ち上げる。第２無端チェーンの内側走行部が、コンベアの側方且つ離隔方向へ往復移動する際に、第２無端チェーンの爪に係合する生鳥篭の蓋の係止爪は、所定時間に亘って弾性変形し生鳥篭の篭本体側壁から離れる。第１無端チェーンの内側走行部が、篭本体側壁に当接することにより、篭本体側壁の、外方へのスプリングバックが防止される。この結果、係止爪は、篭本体側壁から容易に離れることができる。生鳥篭の蓋の係止爪が篭本体側壁から離れることにより、係止爪と篭本体の上端に形成された外フランジの外縁下端との係合が解除される。蓋の係止爪との係合が解除された篭本体は自重で下方へ移動する。生鳥篭の蓋に形成された係止爪と篭本体の上端に形成された外フランジの外縁下端との係合が、コンベアにより搬送される生鳥篭の進行方向前方の係止爪から後方の係止爪へ向けて順次解除され、生鳥篭の蓋が篭本体から取り外される。第２無端チェーンがコンベアに対して上方へ相対移動するのに伴って、第２無端チェーンの爪に係合した蓋は、自重で下方へ移動しコンベア上に戻った篭本体から上方へ遠ざかる。
上記説明から分かるように、本発明に係る装置は、食鳥処理工場の搬送コンベアに載置された生鳥篭から蓋を自動的に取り外すことが可能である。
【０００５】
本発明の好ましい態様においては、第２無端チェーンの内側走行部は、コンベアの側方且つ離隔方向へ往復移動する前に、コンベアの側方且つ近接方向へ移動する。
第２無端チェーンの内側走行部が、コンベアの側方且つ離隔方向へ往復移動する前に、コンベアの側方且つ近接方向へ移動すると、第２無端チェーンに取り付けられた爪が生鳥篭の篭本体の側壁を内側へ弾性変形させるので、生鳥篭の蓋に形成された係止爪と篭本体の側壁との間の隙間が広がり、第２無端チェーンに取り付けられた爪が生鳥篭の蓋に形成された係止爪と係合し易くなる。
【０００６】
本発明の好ましい態様においては、生鳥篭蓋取り外し装置は、第２無端チェーンの内側走行部の近傍上方に且つ第２無端チェーンの内側走行部に略平行に配設され、下側走行部が第２無端チェーンの内側走行部と同一方向に走行する一対の第３無端チェーンを備える。
第３無端チェーンの下側走行部が、生鳥篭の蓋を上方から押さえるので、蓋を篭本体から取り外す際に蓋の挙動が不安定にならない。
【０００７】
本発明の好ましい態様においては、生鳥篭蓋取り外し装置は、第２無端チェーンの内側走行部よりもコンベア中心側に配設されると共に上側走行部の始端部が２無端チェーンの内側走行部の終端近傍部と略同一高さに位置決めされ、上側走行部が第２無端チェーンの内側走行部と同一方向に走行しつつ第２無端チェーンの内側走行部よりも大きな傾斜でコンベアに対して上方へ相対移動する一対の第４無端チェーンを備える。
生鳥篭の蓋が第２無端チェーンから第４無端チェーンへ乗り移るので、第２無端チェーンの内側走行部の終端近傍で蓋が両方の第２無端チェーンの内側走行部に引っ張られて破損する事態の発生が防止される。
【０００８】
本発明の好ましい態様においては、第１無端チェーンの内側走行部の終端近傍部はコンベアと同一方向に走行しつつコンベアの側方且つ離隔方向へ移動する。第１無端チェーンの内側走行部の終端近傍部がコンベアと同一方向に走行しつつコンベアの側方且つ離隔方向へ移動することにより、第１無端チェーンが生鳥篭の篭本体側壁から離れる。篭本体が自重により下方へ移動する際の抵抗が減少するので、篭本体は速やかにコンベア上に戻ることができる。
【０００９】
本発明の好ましい態様においては、第１無端チェーンと第２無端チェーンとは一体に組み付けられている。
第１無端チェーンと第２無端チェーンとが一体に組み付けられることにより、生鳥篭蓋取り外し装置が小型化する。
【００１０】
本発明の好ましい態様においては、生鳥篭蓋取り外し装置は、コンベアの第２無端チェーンよりも下流域の上方に配設されコンベアに沿って食鳥処理装置の近傍まで延在する覆部材を備える。
覆部材を配設することにより、
生鳥篭が食鳥処理装置の近傍に到達する前に、蓋が取り外され上端が開放された生鳥篭の篭本体から、生鳥が逃げ出す事態の発生が防止される。
【００１１】
【発明の実施の形態】
本発明の実施例に係る生鳥篭蓋取り外し装置を説明する。
図８に示すように、食鳥処理ラインは蛇行する搬送コンベア２００を備えている。搬送コンベア２００は黒矢印で示す方向へ走行する。搬送コンベア２００の始端近傍部に生鳥篭積み降し装置３００が配設され、中央部に生鳥篭蓋取り外し装置１が配設されている。搬送コンベア２００の終端部は、図示しない食鳥処理装置に接続している。
【００１２】

【００１３】
図１１、図１２に示すように、第１無端チェーン内側走行部２ａはガイド２ｂにより案内されており、始端近傍部２ａ１及び中央部２ａ２は搬送コンベア２００に略平行に走行し、終端近傍部２ａ３は搬送コンベア２００の側方且つ離隔方向へ移動する。
図１１、図１２に示すように、第２無端チェーン内側走行部３ａはガイド２ｂ、３ｂ、３ｃ、３ｄにより案内されており、始端近傍部３ａ１は搬送コンベア２００の側方且つ近接方向へ移動し、中央部３ａ２は搬送コンベア２００の側方且つ離隔方向へ往復移動し、終端近傍部３ａ３は搬送コンベア２００に略平行に走行する
【００１４】
図９〜図１１に示すように、多数の爪４が、第２無端チェーン３の延在方向に互いに微少隙間を隔てて、第２無端チェーン３に取り付けられている。爪４は、第２無端チェーン内側走行部３ａから搬送コンベア２００の中心方向へ突出している。爪４の先端部は上方へ屈曲している。
【００１５】
図９〜図１１に示すように、一対の第３無端チェーン５が、第２無端チェーン内側走行部３ａよりも搬送コンベア２００の中心側に配設されている。第３無端チェーン５は、第２無端チェーン内側走行部３ａの中央部３ａ２及び終端近傍部３ａ３の近傍上方に且つ第２無端チェーン内側走行部３ａに略平行に配設されている。図１０に二重白抜き矢印で示すように、第３無端チェーン５の下側走行部５ａは、第２無端チェーン内側走行部３ａと同一方向に走行する。
【００１６】
図９〜図１１に示すように、一対の第４無端チェーン６が、第２無端チェーン内側走行部３ａよりも搬送コンベア２００の中心側に配設されている。第４無端チェーン６は、第２無端チェーン内側走行部３ａの終端部近傍に配設されている。第４無端チェーン６は、第２無端チェーン内側走行部３ａの終端部を越えて延在している。第４無端チェーン６の上側走行部６ａの始端部は、第２無端チェーン内側走行部３ａの終端近傍部３ａ３と略同一高さに位置決めされている。第４無端チェーン６の上側走行部６ａは、図１０に二重黒矢印で示すように、第２無端チェーン内側走行部３ａと同一方向に走行しつつ、第２無端チェーン内側走行部３ａよりも大きな傾斜で搬送コンベア２００に対して上方へ相対移動する。
【００１７】
図１０に示すように、搬送コンベア２００の、第２無端チェーン３内側走行部の終端近傍部３ａ３に隣接する部位から終端部に至る領域の上方に、搬送コンベア２００に沿って延在する覆部材７が配設されている。
【００１８】
生鳥篭蓋取り外し装置１の作動を説明する。
多段に積み重ねられた状態で食鳥処理工場へ到着した生鳥篭１００は、生鳥篭積み降し装置３００により、最下段の生鳥篭１００から順次生鳥処理ラインの搬送コンベア２００上に積み降ろされる。
搬送コンベア２００上に載置された生鳥篭１００は、搬送コンベア２００の走行に伴って、生鳥篭蓋取り外し装置１に到達する。
【００１９】
図１３（ａ）に示すように、搬送コンベア２００と同一方向に同一速度で走行する第１無端チェーン内側走行部２ａの始端近傍部２ａ１が、篭本体１０１の長辺側側壁のリブ１０１ｂ下部に当接する。次いで、図１３（ｂ）に示すように、搬送コンベア２００と同一方向に同一速度で走行する第２無端チェーン内側走行部３ａの始端近傍部３ａ１から、搬送コンベア２００の中心方向へ向けて突出する爪４が、篭本体１０１の長辺側側壁のリブ１０１ｂ上部に当接する。
第２無端チェーン内側走行部３ａの始端近傍部３ａ１が、搬送コンベア２００に対して上方へ相対移動しつつ搬送コンベア２００の側方且つ近接方向へ移動するのに伴って、爪４は、図１３（ｃ）に示すように、リブ１０１ｂを内側へ押圧し篭本体１０１の長辺側側壁を内側へ弾性変形させて、蓋１０２の係止爪１０２ｂと篭本体１０１のリブ１０１ｂとの間の側面視の隙間Ｓを押し広げつつ、生鳥篭１００に対して上方へ相対移動する。
第３無端チェーン下側走行部５ａの始端近傍部が生鳥篭の蓋１０２上面に当接する。
【００２０】
図１４（ａ）〜（ｃ）に示すように、爪４は、搬送コンベア２００と同一方向へ走行しつつ、生鳥篭１００に対して上方へ相対移動し続け、蓋１０２の係止爪１０２ｂに下方から係合すると共にリブ１０１ｂに形成された突起に下方から係合する。
爪４は、蓋１０２の係止爪１０２ｂと篭本体１０１のリブ１０１ｂとの間の側面視の隙間Ｓを押し広げつつ、生鳥篭１００に対して上方へ相対移動するので、係止爪１０２ｂに容易に係合することができる。爪４は、図１０に示すように、生鳥篭１００を搬送コンベア２００から持ち上げる。
【００２１】
図１５（ａ）〜（ｃ）、図１６（ａ）〜（ｃ）に示すように、第２無端チェーン内側走行部３ａの中央部３ａ２が、搬送コンベア２００の側方且つ離隔方向へ往復移動する際に、第２無端チェーン内側走行部３ａの中央部３ａ２から搬送コンベア２００の中心方向へ向けて突出する爪４に係合する蓋１０２の係止爪１０２ｂは、所定時間に亘って弾性変形し、側面視で篭本体側壁のリブ１０１ｂから離れる。第１無端チェーン内側走行部２ａが、篭本体側壁のリブ１０１ｂに当接しているので、篭本体１０１の長辺側側壁の、外方へのスプリングバックが防止される。この結果、係止爪１０２ｂは、側面視で篭本体側壁のリブ１０１ｂから容易に離れることができる。蓋１０２の係止爪１０２ｂが側面視で篭本体側壁のリブ１０１ｂから離れることにより、係止爪１０２ｂと篭本体１０１の上端に形成された外フランジ１０１ａの外縁下端との係合が解除される。
蓋１０２に形成された係止爪１０２ｂと篭本体１０１の上端に形成された外フランジ１０１ａの外縁下端との係合が、搬送コンベア２００により搬送される生鳥篭１００の進行方向前方の係止爪１０２ｂから後方の係止爪１０２ｂへ向けて順次解除され、生鳥篭１００の蓋１０２が篭本体１０１から取り外される。
第３無端チェーン５の下側走行部５ａが、生鳥篭の蓋１０２を上方から押さえるので、蓋１０２を篭本体１０１から取り外す際に蓋１０２の挙動は不安定にならない。
【００２２】
蓋１０２の係止爪１０２ｂとの係合が解除された篭本体１０１は、図１０に示すように、自重で下方へ移動する。
第１無端チェーン内側走行部２ａの終端近傍部２ａ３が、搬送コンベア２００と同一方向に走行しつつ搬送コンベア２００の側方且つ離隔方向へ移動し、図１７（ａ）に示すように、第１無端チェーン内側走行部２ａの終端近傍部２ａ３が、篭本体側壁のリブ１０１ｂから離れる。生鳥を収容した篭本体１０１が自重により下方へ移動する際の抵抗が減少するので、篭本体１０１は速やかに搬送コンベア２００上に戻る。
【００２３】
第２無端チェーン内側走行部３ａが搬送コンベアコンベア２００に対して上方へ相対移動するのに伴って、第２無端チェーン内側走行部３ａから搬送コンベア２００の中心方向へ突出する爪４に係合した蓋１０２は、図１０に示すように、自重で下方へ移動し搬送コンベア２００上に戻った篭本体１０１から上方へ遠ざかる。
【００２４】
図１０、図１７（ｂ）に示すように、蓋１０２は、第２無端チェーン内側走行部３ａの終端近傍部３ａ３から、第４無端チェーン上側走行部６ａの始端近傍部に乗り移る。
蓋１０２が、第２無端チェーン３から第４無端チェーン６に乗り移ることにより、第２無端チェーン内側走行部３ａの終端近傍で、蓋１０２が両方の第２無端チェーン内側走行部３ａに引っ張られて破損する事態の発生が防止される。
第４無端チェーン上側走行部６ａに乗り移った蓋１０２は、第４無端チェーン上側走行部６ａの終端部で回収される。
【００２５】
第１無端チェーン２と第２無端チェーン３とが一体に組み付けられることにより、生鳥篭蓋取り外し装置１が小型化されている。
図７から分かるように、搬送コンベア２００の、第２無端チェーン内側走行部３ａの終端近傍部３ａ３よりも下流域の上方に配設され、搬送コンベア２００に沿って食鳥処理装置の近傍まで延在する覆部材７が、篭本体１０１の開放された上端を覆うので、篭本体１０１から生鳥が逃げ出す事態の発生が防止される。
【００２６】

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a live bird cage lid removing device.
[0002]
[Prior art]
Live bird cages are used to transport live birds from poultry farms to poultry processing plants.
As shown in FIGS. 1 to 7, a live bird cage 100 generally has a side wall and a bottom wall of a lattice structure and an inverted quadrangular truncated pyramid shape having a substantially rectangular shape in plan view and an open upper end, and a cage body. And a lid 102 having a lattice structure, which is locked to the open upper end of 101.
A narrow outer flange 101a is formed at the upper end of the basket main body 101. The outer edge of the outer flange 101a is bent downward.
Two pairs of ribs 101b extending vertically are formed on the outer surface of the long side wall of the basket main body 101 at intervals in the direction in which the side wall extends. When the live bird cage 100 arriving at the poultry processing factory in a state of being stacked in multiple stages is loaded and unloaded onto the transport conveyor of the live bird processing line from the live bird cage 100 at the bottom using the loading / unloading device, the loading / unloading is performed. The claw of the unloading device is engaged with the lower end of the rib 100b of the live bird cage located just above the live bird cage to hold the live bird cage immediately above and the live bird cage further above.
The outer peripheral edge 102a of the lid 102 is bent downward. A pair of locking claws 102b extend from the lower end of the outer peripheral edge on the long side of the lid 102 at a distance from each other in the extending direction of the long side. The lid 102 is locked to the upper end of the basket main body 101 in a state where the locking claw 102b is engaged with the lower end of the outer edge of the outer flange 101a of the basket main body 101. An opening 102d that can be opened and closed by a sliding door 102c is formed in the lid 102.
[0003]
[Problems to be solved by the invention]
In the poultry processing plant, conventionally, when the live bird cage 100 is transported to the vicinity of the bird poultry processing device by the transport conveyor, the worker pulls the sliding door 102c to open the opening 102d, and from the live bird cage 100 through the opening 102d. Raw birds were taken out one by one and hung on a hanger of a poultry processing device. As a result, when taking out a live bird from the live bird cage 100, there were many accidents in which the live bird was damaged by interference with the edge of the opening 102d. In addition, since the used live bird cage 100 was washed with the lid 102 attached, dirt inside the live bird cage could not be sufficiently removed.
The present invention has been made in view of the above problems, and has as its object to provide an apparatus that automatically removes a lid from a live bird cage placed on a transport conveyor of a poultry processing plant.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, in the present invention, a conveyor on which a live bird cage is placed, and disposed on both sides of the conveyor, the inner traveling part travels in the same direction as the conveyor and is placed on the conveyor. A pair of first endless chains abutting on a pair of opposite side walls of the live bird cage, and disposed on both sides of the conveyor and above the first endless chain, and the inner running portion runs in the same direction as the conveyor while moving in the same direction as the conveyor. And a pair of second endless chains reciprocating in the lateral and distant directions of the conveyor, and attached to the second endless chains with a small gap therebetween. A live bird cage lid removing device, comprising: a plurality of claws protruding in the center direction and engaging with locking claws formed on a live bird cage lid.
When the inner running portion of the second endless chain moves upward in the same direction as the conveyor and relatively moves with respect to the conveyor, the claws projecting from the inner running portion of the second endless chain toward the center of the conveyer have a live bird cage. The birdcage is engaged with the locking claw formed on the lid from below, and the live bird cage is lifted from the conveyor. When the inner running portion of the second endless chain reciprocates sideways and away from the conveyor, the locking claws of the lid of the live bird cage that engage with the claws of the second endless chain are elastic for a predetermined time. Deforms and moves away from the side wall of the live bird cage. The inner running portion of the first endless chain abuts against the side wall of the basket main body, thereby preventing the basket main body side wall from springback outward. As a result, the locking claw can be easily separated from the basket body side wall. When the locking claw of the lid of the live bird cage is separated from the side wall of the basket main body, the engagement between the locking claw and the lower end of the outer edge of the outer flange formed on the upper end of the basket main body is released. The cage body released from engagement with the locking claw of the lid moves downward by its own weight. The engagement between the locking claw formed on the lid of the live bird cage and the lower end of the outer edge of the outer flange formed on the upper end of the basket main body engages with the rear hook from the front locking claw in the traveling direction of the live bird cage conveyed by the conveyor.
