【0021】
そして、この構成では、搬送手段で搬送する物品の搬送方向の始端および終端を検知手段で検知し、氷除去手段では、検知手段による検知に基づき搬送手段で搬送する物品の表面における搬送方向の始端および終端より内側の範囲にブラシを接触させるため、物品の始端および終端のエッジ部分が回転するブラシとの接触で破損するのを防止できるとともに、物品の搬送に影響を与えることなく砕氷した氷を確実に払い落とすことができる。

【0024】
【発明の実施の形態】
以下、本発明の一実施の形態を図面を参照して説明する。
【0025】
図5において、11は物品としてのケースで、このケース11は、ダンボールケースであって、長方形状の箱であり、長手方向に沿った両側面12および長手方向と交差する短手方向に沿った両端面13で周面が形成され、これら両側面12および両端面13の下面側の各辺に形成された図示しない下面側のフラップがケース11の底部に折り曲げられて固定され、ケース11の底部が閉塞されている。
【0026】
両側面12の上面側の両側辺に形成された両側のフラップ14、および両端面13の上面側の両端辺に形成された両端のフラップ15がそれぞれケース11の上面に折り曲げられ、一側のフラップ14の先端側両角部が両端のフラップ15に形成された取付孔16に内側から外側に差し込まれ、他側のフラップ14の先端側両角部が両端のフラップ15に形成された取付孔17に外側から内側に差し込まれ、これらフラップ14,15がケース11の上面を閉じた状態で係止されている。
【0027】
そして、ケース11は冷凍物を収納して冷凍倉庫などに冷凍保管され、冷凍物の出荷時に冷凍倉庫に冷凍保管していたケース11を取り出し、自動搬送するラインを通じて所定の場所に搬送する。冷凍倉庫から取り出したケース11の表面である上面には余分な氷が氷結している場合があり、フラップ14,15を開くことが困難となっている。
【0028】
次に、図1ないし図6において、21は氷除去装置で、この氷除去装置21は、ケース11を自動搬送するライン中に配設されてケース11の上面に氷結している氷を除去するもので、ライン中に接続されてケース11を搬送する搬送手段としてのコンベヤ22を有している。このコンベヤ22は、ベルトコンベヤであって、無端状のベルト23が搬送方向Fの始端側のプーリおよび終端側のプーリ24を含む複数のプーリによって張設され、ベルト23の上面が搬送方向Fの始端側のプーリから終端側のプーリ24に移動するように図示しないコンベヤモータで回転駆動される。ベルト23の上面がケース11を載せて搬送方向Fに搬送する搬送面25として構成されている。コンベヤ22で搬送するケース11の向きは、搬送方向Fにケース11の長手方向を向け、一方の端面13を先頭として搬送する。
【0029】
また、コンベヤ22を跨ぐようにフレーム28が立設され、このフレーム28に、コンベヤ22で砕氷位置29に搬送されて停止されたケース11を位置決めする位置決め手段30、砕氷位置29に位置決めされたケース11の上面の氷を砕氷する砕氷手段31、および砕氷位置29より搬送方向Fの下流側にコンベヤ22で搬送するケース11の上面の砕氷された氷を除去する氷除去手段32が取り付けられている。
【0030】
図5に示すように、位置決め手段30は、砕氷位置29における搬送方向Fに対し交差する両側に配置されケース11の長手方向に沿った両側面12に当接して位置決めする一対の位置決めプレート35を有している。これら各位置決めプレート35は、フレーム28に取り付けられた位置決めシリンダ36から水平方向に進退するロッド36aに取り付けられ、位置決めシリンダ36の作動によって、位置決めプレート35でケース11の両側面12を押圧して砕氷位置29の中央を基準に位置決めする進出位置とケース11の両側面の領域から退避してケース11のコンベヤ22による搬送を許容する退避位置との間で移動する。
【0031】
図1に示すように、砕氷位置29には、コンベヤ22で搬送するケース11が砕氷位置29に到達したことを検知する砕氷位置検知手段としての光電スイッチ37が配設されている。
【0032】
また、図1、図2および図6に示すように、砕氷手段31は、砕氷位置29の上方でフレーム28に取り付けられたベース40を有し、このベース40の一面両側にガイド部41が取り付けられ、これらガイド部41間にスライド部42が上下方向にスライド可能に取り付けられている。スライド部42には、砕氷刃駆動部としての第1のシリンダ43が取り付けられるとともに、この第1のシリンダ43を跨ぐようにしてスライド部42に取り付けられるブラケット44を介して砕氷刃駆動部としての第2のシリンダ45が取り付けられている。
【0033】
第1のシリンダ43の下端から進退するロッド43aの先端に第1の砕氷刃ホルダ46が取り付けられ、第2のシリンダ45の下端から進退するロッド45aの先端に第2の砕氷刃ホルダ47が取り付けられている。図3に示すように、第1の砕氷刃ホルダ46は略E字形に形成され、第2の砕氷刃ホルダ47は略C字形に形成され、これら第1の砕氷刃ホルダ46と第2の砕氷刃ホルダ47とが非接触状態で互いに組み合うように構成されている。
【0034】
第1の砕氷刃ホルダ46の略E字形の各端部に砕氷刃として第1の砕氷刃48が取り付けられ、第2の砕氷刃ホルダ47の略C字形の各端部の下面に砕氷刃として第2の砕氷刃49が取り付けられ、これら砕氷刃48,49が搬送方向Fに対応する方向に間隔をあけて一列に並設されている。各砕氷刃48,49は、並設方向に対し交差する方向に板状で、先端が鋭角に形成されているとともに、並設方向に対し交差する方向の先端形状が両側部より中央部が突出した凸形に形成されている。一列に並ぶ砕氷刃48,49の並設方向の幅および並設方向に対し交差する方向の幅は、ケース11の長手方向の幅および短手方向の幅より小さく形成されている。
【0035】
図1、図2および図6に示すように、フレーム28に螺合部材50が固定され、この螺合部材50にねじ軸51が螺合貫通され、このねじ軸51の下端がスライド部42の上部に設けられた連結部52に回動可能に連結されている。ねじ軸51の上端にはねじ軸51を回動操作するハンドル53が取り付けられている。そして、ハンドル53の回動操作によってスライド部42が上下方向に移動し、すなわち、ケース11の種類毎の高さに応じてケース11の上面に対する砕氷手段31の間隔つまり高さを調整する調整手段54が構成されている。
【0036】
そして、調整手段54によって砕氷手段31の高さが処理するケース11の種類つまり高さに応じて調整された状態において、各シリンダ43,45の作動によって、各砕氷刃48,49がケース11の上面より下降してケース11の上面の氷を砕氷する下降位置とケース11の上面より上昇した上昇位置との間で移動する。
【0037】
また、図1および図4に示すように、氷除去手段32は、コンベヤ22上の砕氷位置29より下流側の氷払落し位置56においてコンベヤ22で搬送するケース11の搬送域より上方に配設されており、両側の揺動プレート57の中間部が横継ぎ部材58によって一体に連結されて構成されたブラシ支持体59を有し、このブラシ支持体59の両側の揺動プレート57の基端がフレーム28の両側の支持プレート60の軸受61に回動可能に軸支された支軸62を支点として揺動可能に支持されている。
【0038】
ブラシ支持体59の両側の揺動プレート57の先端間には軸受63によって回転軸64が回転自在に軸支され、一側の揺動プレート57の外面に回転軸64を回転方向Rに回転駆動するブラシ回転駆動部としてのブラシ回転モータ65が取り付けられている。回転軸64の中央にはブラシ66が取り付けられ、このブラシ66は、複数のブラシ毛が中心側から外径方向に向けて突出するように保持されたもので、回転方向Rに対し交差する方向つまり軸方向の先端形状が両側部より中央部が突出した円弧状の凸形に形成されている。ブラシ66の回転方向Rに対し交差する方向つまり軸方向の幅は、ケース11の上面の幅と略同一に形成されている。
【0039】
ブラシ支持体59の上方のフレーム28にはブラシ接離駆動部としてのブラシ昇降シリンダ67が回動可能に支持する支持ユニット68を介して取り付けられ、このブラシ昇降シリンダ67の下端から進退するロッド67aの先端がブラシ支持体59の横継ぎ部材58に回動可能に連結する連結ユニット69を介して連結されている。そして、ブラシ66は、ブラシ昇降シリンダ67の作動によって、ケース11の上面に接触する下降位置とケース11の上面から離反する上昇位置との間で移動する。
【0040】
氷払落し位置56には、コンベヤ22で搬送するケース11の搬送方向Fの始端および終端を検知する検知手段としての始端検知用の光電スイッチ70および終端検知用の光電スイッチ71が配設されている。始端検知用の光電スイッチ70ではケース11で遮光することでケース11の始端を検知し、終端検知用の光電スイッチ71ではケース11で遮光された後に透光状態になることでケース11の終端を検知する。そして、氷除去手段32では、光電スイッチ70,71による検知に基づきコンベヤ22で搬送するケース11の上面における搬送方向Fの始端および終端より内側の範囲にブラシ66を接触させるようにブラシ昇降シリンダ67を制御する。
【0041】
また、氷払落し位置56の搬送方向Fの下流側には、回転するブラシ66によってケース11の上面から搬送方向Fの下流側へ向けて払い落とされる氷を受け止めて飛散を防止するカーテン74が配設されている。このカーテン74は、搬送方向Fと交差する方向に複数に分割された帯状で、上端がカーテン支持部75に取り付けられて吊下げ状態に支持され、ケース11の通過を可能としている。
【0042】
また、コンベヤ22のベルト23の終端側のプーリ24から始端側のプーリに戻るリターン側78には、ベルト23の表面に接してその表面に付着している氷を払い落とすベルト用ブラシ79が配設されている。
【0043】
次に、本実施の形態の作用を説明する。
【0044】
予め、処理するケース11の種類つまり高さに応じて、調整手段54のハンドル53を操作して砕氷手段31の高さを調整する。待機状態では、各砕氷刃48,49およびブラシ66ともケース11の上面より上昇した上昇位置にあってコンベヤ22によるケース11の搬送を可能としている。
【0045】
コンベヤ22で搬送方向Fに搬送するケース11を砕氷位置検知用の光電スイッチ37で検知すれば、コンベヤ22を直ちに停止し、ケース11を砕氷位置29に停止させる。
【0046】
位置決め手段30の両側の位置決めシリンダ36を作動させて両側の位置決めプレート35でケース11を挟み込んでセンタリングし、ケース11を砕氷位置29に位置決めする。
【0047】
砕氷手段31の第1のシリンダ43を作動させて第1の砕氷刃48を下降させ、第1の砕氷刃48をケース11の上面に氷結している氷に打ち付け、砕氷する。続いて、第1のシリンダ43を作動させて第1の砕氷刃48を上昇させるのと同時に、第2のシリンダ45を作動させて第2の砕氷刃49を下降させ、第2の砕氷刃49をケース11の上面に氷結している氷に打ち付け、砕氷する。続いて、第2のシリンダ45を作動させて第2の砕氷刃49を上昇させるのと同時に、第1のシリンダ43を作動させて第1の砕氷刃48を下降させる。このように、第1の砕氷刃48と第2の砕氷刃49とを交互に所定回数上下させ、ケース11の上面に氷結している氷に打ち付け、砕氷する。
【0048】
第1の砕氷刃48と第2の砕氷刃49とを交互に上下させるため、例えば全ての砕氷刃48,49を同一タイングで上下させる場合に比べて、1つの砕氷刃48,49から氷に加わる力が集中して氷を砕氷しやすくできるとともに、例えばある一定時間内で氷に対して砕氷刃48,49が当接する回数を2倍に多くできて氷を早く砕氷できる。しかも、複数の砕氷刃48,49を、間隔をあけて並設し、その並設方向に対し交差する方向に板状で、かつ並設方向に対し交差する方向の先端形状を凸形に形成したため、例えばケース11の上面が窪んでいるような場合でも、ケース11を損傷させずに氷を確実に砕氷できる。
【0049】
また、各砕氷刃48,49を交互に所定回数上下させた後、各砕氷刃48,49ともケース11の上面より上昇した上昇位置に戻し、コンベヤ22によるケース11の搬送を再開する。同時に、ブラシ回転モータ65によってブラシ66を回転方向Rに回転させる。
【0050】
コンベヤ22で搬送方向Fに搬送するケース11の始端を始端検知用の光電スイッチ70が検知すれば、ブラシ昇降シリンダ67を作動させてブラシ66を下降させる。ブラシ66は、コンベヤ22によるケース11の搬送速度とブラシ66の下降速度との関係から、ケース11の状面における搬送方向Fの始端より内側に接触する。
【0051】
回転するブラシ66がケース11の上面に接触することで、砕氷手段31で砕氷されている氷を搬送方向Fの下流側へ向けて払い落とす。ケース11の上面におけるブラシ66の接触位置は、コンベヤ22によるケース11の搬送に伴って搬送方向Fの終端側に向けて移動していく。このとき、ブラシ66は、回転方向に対し交差する方向の先端形状を凸形に形成したため、例えばケース11の表面が窪んでいるような場合でも、破砕した氷を確実に払い落とすことができる。
【0052】
ケース11の上面におけるブラシ66の接触位置が搬送方向Fの終端側に達する直前に、コンベヤ22で搬送方向Fに搬送するケース11の終端を終端検知用の光電スイッチ71が検知し、ブラシ昇降シリンダ67を作動させてブラシ66を上昇させる。
【0053】
このように、コンベヤ22で搬送するケース11の搬送方向の始端および終端を光電スイッチ70,71で検知し、コンベヤ22で搬送するケース11の表面における搬送方向Fの始端および終端より内側の範囲にブラシ66を接触させるため、ケース11の始端および終端のエッジ部分が回転するブラシ66との接触で破損するのを防止できるとともに、ケース11の搬送に影響を与えることなく砕氷した氷を確実に払い落とすことができる。
【0054】
コンベヤ22で氷を除去したケース11を下流側の次工程に搬送し、一連の氷除去動作を完了する。
【0055】
このように、砕氷手段31のシリンダ43,45でケース11の表面に対して接離移動させる砕氷刃48,49を、コンベヤ22で搬送するケース11の表面に氷結した氷に当接させて砕氷するため、ケース11の表面に氷結した氷を自動的に砕氷し、ケース11のフラップ14,15の開放が可能になり、自動化ラインにも対応できる。
【0056】
さらに、コンベヤ22でケース11を搬送する搬送方向Fの砕氷手段31より下流側に設けられた氷除去手段32により、回転するブラシ66をケース11の上面に接触させ、砕氷手段31で砕氷されたケース11の上面の氷を確実に払い落とし、氷を除去できる。
【0057】
そして、調整手段54により、ケース11の種類に応じてケース11の上面に対する砕氷手段31の高さを調整でき、多種類のケース11に対応できる。
【0058】
なお、砕氷手段31において、2群に分けた砕氷刃48,49を2つのシリンダ43,45で交互に上下させることで氷を砕氷しやすくかつ早く砕氷できるが、砕氷刃48,49を3群以上に分けて3つ以上のシリンダで任意に上下させるように構成すればより氷を砕氷しやすくかつより早く砕氷でき、また、砕氷刃48,49を同時に上下させるように構成すればシリンダが1つで済んで構造を簡略化できる。
【0059】
また、砕氷手段31の砕氷刃としては、板状に限らず、アイスピックのような先の尖ったピンなどを用いることもができる。
【0060】
また、砕氷手段31の砕氷刃48,49に対してケース11側を移動させて砕氷してもよく、あるいは砕氷刃48,49とケース11との両方を移動させて砕氷してもよい。
【0061】
また、氷除去手段32は、回転するブラシ66に限らず、固定的に配置したブラシでもよく、あるいは、例えばエアをケース11の上面に吹き付けて氷を吹き飛ばしたり、ケース11を傾けて氷を滑り落としてもよい。
【0062】
また、物品としては、ダンボールケースなどのケース11に限らず、容器、箱、その他の表面に氷が氷結しているものを対象とする。
【0063】

[0051]
When the rotating brush 66 comes into contact with the upper surface of the case 11, the ice that has been crushed by the ice breaking means 31 is wiped down toward the downstream side in the transport direction F. The contact position of the brush 66 on the upper surface of the case 11 moves toward the end side in the transport direction F as the case 11 is transported by the conveyor 22. At this time, since the brush 66 has a convex tip shape in a direction intersecting the rotation direction, for example, even when the surface of the case 11 is depressed, the crushed ice can be surely removed.
[0052]
Immediately before the contact position of the brush 66 on the upper surface of the case 11 reaches the end side in the transport direction F, the end of the case 11 transported in the transport direction F by the conveyor 22 is detected by the end detection photoelectric switch 71, and the brush lifting cylinder Actuate 67 to raise brush 66.
[0053]
In this way, the start and end of the transport direction of the case 11 transported by the conveyor 22 are detected by the photoelectric switches 70 and 71, and within the range inside the start and end of the transport direction F on the surface of the case 11 transported by the conveyor 22 Since the brush 66 is brought into contact, the start and end edge portions of the case 11 can be prevented from being damaged by contact with the rotating brush 66, and the crushed ice can be surely removed without affecting the transport of the case 11. Can be dropped.
[0054]
The case 11 from which the ice has been removed by the conveyor 22 is conveyed to the next downstream process, and a series of ice removing operations is completed.
[0055]
In this way, the ice breaking blades 48 and 49 moved to and away from the surface of the case 11 by the cylinders 43 and 45 of the ice breaking means 31 are brought into contact with the ice frozen on the surface of the case 11 conveyed by the conveyor 22 to break the ice. Therefore, the ice frozen on the surface of the case 11 can be automatically crushed, and the flaps 14 and 15 of the case 11 can be opened, so that the automation line can be used.
[0056]
Further, the rotating brush 66 is brought into contact with the upper surface of the case 11 by the ice removing means 32 provided on the downstream side of the ice breaking means 31 in the conveying direction F for conveying the case 11 by the conveyor 22, and the ice breaking means 31 breaks the ice. The ice on the upper surface of the case 11 can be surely removed to remove the ice.
[0057]
Then, the height of the ice breaking means 31 relative to the upper surface of the case 11 can be adjusted by the adjusting means 54 according to the type of the case 11, so that various types of cases 11 can be handled.
[0058]
In the ice breaking means 31, the ice breaking blades 48, 49 divided into two groups are alternately moved up and down by two cylinders 43, 45 so that the ice can be easily and quickly broken. Dividing the above into three or more cylinders can be made to move up and down arbitrarily, making it easier to break ice and breaking faster, and if the ice breaking blades 48 and 49 are moved up and down simultaneously, one cylinder It can be completed and the structure can be simplified.
[0059]
Further, the ice breaking blade of the ice breaking means 31 is not limited to a plate shape, and a pointed pin such as an ice pick can also be used.
[0060]
Further, the ice breaking means 31 may move the case 11 side with respect to the ice breaking blades 48 and 49 to break the ice, or both the ice breaking blades 48 and 49 and the case 11 may be moved to break the ice.
[0061]
