Description

【０００１】
【発明の属する技術分野】
この発明は、例えば、ゼリーのようなデザートを満杯充填した容器を蓋材でシールするシール装置に関する。
【０００２】
【従来の技術】
この種の装置としては、所定のシール区間を経由して前向きに移動するスラットを有する連続駆動コンベヤと、下降、下限前進、上昇および上限後退を含むボックスモーションをさせられかつシール区間を移動する間に容器搬送速度と同速度で下限前進モーションさせられて、蓋材を介して容器の口縁部に押圧されるシールヘッドとを備えており、シールヘッドのモーションが、ボックスモーションカム機構によって与えられるようになされているものが知られている。
【０００３】
【発明が解決しようとする課題】
上記装置では、コンベヤのスラットの取付方にがたや遊びがあり、スラットのピッチがずれている場合でも、シールヘッドのモーションは一定であるため、ピッチがずれたままでシールが行われる。そうすると、スラットに保持された容器のセンタとシールヘッドのセンタがずれてしまい、シール不良を起こす心配がある。
【０００４】
この発明の目的は、シール不良の心配がない容器のシール装置を提供することにある。
【０００５】
【課題を解決するための手段】
この発明による容器のシール装置は、所定のシール区間を経由して前向きに移動するスラットを有する連続駆動コンベヤと、下降、下限前進、上昇および上限後退を含むボックスモーションをさせられかつシール区間を移動する間に容器搬送速度と同速度で下限前進モーションさせられて、蓋材を介して容器の口縁部に押圧されるシールヘッドとを備えている容器のシール装置において、シール区間の上方に、シールヘッド前後動用移動体が前後往復動しうるように配置され、シールヘッド前後動用移動体から、垂直下向きシールヘッド昇降用流体圧シリンダを介してシールヘッドを取付けたシールヘッド取付板が、その位置を任意の水平方向に変更しうるように吊下げられ、シールヘッド取付板に垂直状下向き位置決めロッドが昇降自在に設けられ、下限時の下向き位置決めロッドの下端部をはめ入れる上向き凹所がスラットに設けられていることを特徴とするものである。
【０００６】
この発明による容器のシール装置では、シール区間の上方に、シールヘッド前後動用移動体が前後往復動しうるように配置され、シールヘッド前後動用移動体から、垂直下向きシールヘッド昇降用流体圧シリンダを介してシールヘッドを取付けたシールヘッド取付板が吊下げられているから、移動体によってシールヘッドの前進・後退のモーションが与えられ、流体圧シリンダによってシールヘッドの下降・上昇のモーションが与えられる。
【０００７】
さらに、シールヘッド取付板が、その位置を任意の水平方向に変更しうるようになされており、シールヘッド取付板に垂直状下向き位置決めロッドが昇降自在に設けられ、下限時の下向き位置決めロッドの下端部をはめ入れる上向き凹所がスラットに設けられているから、スラットのずれに対応してシールヘッド取付板が移動させられ、位置決めロッドと凹所によってスラットとシールヘッド取付板の位置決めがなされる。したがって、スラットに保持された容器のセンタとシールヘッドのセンタがずれる心配がない。
【０００８】
さらに、シールヘッド取付板に垂直状上向き位置決めロッドが昇降自在に設けられ、上限時の上向き位置決めロッドの上端部をはめ入れる下向き凹所がシールヘッド前後動用移動体に設けられていると、シールヘッドの上限後退時において、シールヘッド取付板の移動が拘束される。
【０００９】
また、シールヘッド取付板に複動式両ロッドシリンダが垂直に取付けられ、シリンダの下向きピストンロッドに下向き位置決めロッドが、その上向きピストンロッドに上向き位置決めロッドがそれぞれ取付けられていると、簡単な機構で両位置決めロッドを昇降させることができる。
【００１０】
さらに、シールヘッド前後動用移動体に平行リンクの上端が球面軸受を介して連結され、シールヘッド取付板に平行リンクの下端が球面軸受を介して連結されていると、シールヘッド取付板を安定姿勢で移動させることができる。
【００１１】
さらに、下向き位置決めロッドの下端部および上向き位置決めロッドの上端部にテーパ部がそれぞれ設けられ、上向き凹所および下向き凹所が、円形の開口縁部をそれぞれ有していると、両位置決めロッドを両凹所にそれぞれスムースにはめ入れることができる。
【００１２】
【発明の実施の形態】

第１次シールユニット17および第２次シールユニット18は、同一構造のものであるから、以下、第１次シールユニット17について説明し、第２次シールユニット18の説明は省略する。
【００２６】
第１次シールユニット17は、最も後側で対をなす２つのユニット吊下げレール61のユニット取付部61a に２つずつ吊下げられている４つの吊下げロッド71と、これら吊下げロッド71の下端に前後から挟まれるように渡し止められている水平ユニット取付板72と、ユニット取付板72の上面に垂直下向きに装備されかつユニット取付板72に貫通させられてその下方に突出させられたピストンロッド73を有する４つのシール用流体圧シリンダ74と、これら流体圧シリンダ74のピストンロッド73に固定されている４つの水平円板状押圧部材75と、これら押圧部材75の下方に配されかつ図示しないヒータを内蔵しているシールヘッド76と、各シールヘッド76に直立状に設けられかつ押圧部材75に貫通させられている４つのガイドロッド77と、各ガイドロッド77の上方突出部に固定されているストッパ78と、各ガイドロッド77にはめられて押圧部材75とシールヘッド76の間に介在させられている圧縮コイルばね79とを備えている。
【００２７】
吊下げロッド71の上下連結端には球面軸受71a が介在されており、これにより、ユニット取付板72が前後および左右方向を含むいずれの水平方向にも水平姿勢を保持したまま移動できるようになっている。
【００２８】
ユニット取付板72の左右両端部下面には逆Ｌ字状ブラケット81を介して位置決め用流体圧シリンダ82が取付けられている。流体圧シリンダ82は、複動式の両ロッドシリンダで、上位置決め孔66と同心状の上向きピストンロッド83および下向きピストンロッド84を有している。上向きピストンロッド83は、ユニット取付板72にあけられたロッド孔85に通されている。上向きピストンロッド83には先端テーパ付き上位置決めロッド86が、下向きピストンロッド84には先端テーパ付き下位置決めロッド87がそれぞれ連結されている。上位置決めロッド86は、ロッド孔85の上面縁部に設けられた上ガイド部材88に貫通させられている。下位置決めロッド87は、ブラケット81の下端に設けられた下ガイド部材89に貫通させられている。
【００２９】
図６を参照すると、シールヘッド76は、下降、下限前進、上昇および上限後退モーションを含むボックスモーションをさせられる。１サイクル３６０°のうち、２７０°が前進にあてられ、９０°が後退にあてられる。前進および後退は、前後動体14の作動により、下降および上昇は、流体圧シリンダ74の作動による。前後動体14が後退限から加速前進してスラット22と同速となった後（３０°）、シールヘッド76の下降モーションが行われ、前後動体14が前進限の手前（２４０°）から減速前進し、この間に、シールヘッド76の上昇モーションが完了させられる。これは、シールヘッド76とスラット22の位置ずれを防止するためである。
【００３０】
シールは、隣り合う２つのスラット22に保持された４つの容器Ｃに対して同時に行われる。第１次シールユニット17のシールヘッド76が上限に位置し、前後動体14が後退限に位置する状態で、シールヘッド76の下方の所定位置に、容器Ｃが搬入されると、前後動体14が前進させられる。前後動体14の前進速度がスラット22と同速となると、シールヘッド76が下降させられる。シールヘッド76が下限まで下降させられると、シールヘッド76が蓋材Ｆを介して容器Ｃの口縁部に押圧され、この状態のまま前進限の手前まで移動されられる。この間に、第１次シールが行われる。また、これと同時に、第２次シールユニット18によって第２次シールが行われ、トリミングユニット19によって蓋材Ｆのトリミングが行われる。
【００３１】
シールヘッド76が下降する直前に、位置決め用流体圧シリンダ82の両ピストンロッド83，84が下降させられ、下位置決めロッド87が下位置決め孔24に挿入される。これにより、スラット22とシールヘッド76の位置決めが行われる。この場合、下位置決め孔24と下位置決めロッド87が偏心していると、下位置決めロッド87がその先端テーパ部を下位置決め孔24の開口縁部にそわせながら下降させられることにより、その偏心の分だけユニット取付板72が揺動させられ、両者が同心となる。
【００３２】
前後動体14の前進距離は、スラット22の２ピッチに相当する距離より９０°／３６０°のサイクルに相当する距離だけ短い。前後動体14が前進限の手前まで移動させられると、シールヘッド76が上昇させられる。シールヘッド76の上昇とほぼ同時に、今度は、位置決め用流体圧シリンダ82の両ピストンロッド83，84が上昇させられる。そうすると、上位置決めロッド86が上位置決め孔66に挿入される。これにより、前後動体14とユニット取付板72の位置決めが行われ、これにより、ユニット取付板72の揺動が拘束される。前後動体14が前進限から後退限まで後退すると、１サイクルが完了する。
【００３３】
通常のシール動作を行う場合、ロックボルト68は締め付けられている。シールヘッド76の下面の清掃等を行う場合、ロックボルト68を緩める。そうすると、左右動体16の移動が自由となる。取っ手62を掴んで引っ張ると、図４中鎖線で示すように、可動ガイドレール44からユニット吊下げレール61が抜け出して、シールヘッド76がスラット22の上方から側方に引き出される。そうすると、シールヘッド76の下面の清掃等がスラット22が邪魔になることなく楽に行える。
【００３４】

Referring to FIG. 6, the seal head 76 is subjected to box motion including lowering, lower limit advance, rise and upper limit reverse motions. Of a 360 ° cycle, 270 ° is devoted to advance and 90 ° is devoted to retreat. The forward and backward movements are caused by the operation of the longitudinally moving body 14, and the lowering and raising are caused by the operation of the fluid pressure cylinder 74. After the forward / backward moving body 14 accelerates forward from the backward limit and reaches the same speed as the slat 22 (30 °), a downward motion of the seal head 76 is performed, and the forward / backward moving body 14 advances forward at a reduced speed from just before the forward limit (240 °). During this time, the rising motion of the seal head 76 is completed. This is to prevent the positional deviation between the seal head 76 and the slat 22.
[0030]
Sealing is performed simultaneously on the four containers C held by two adjacent slats 22. When the container C is loaded at a predetermined position below the seal head 76 with the seal head 76 of the primary seal unit 17 positioned at the upper limit and the longitudinal moving body 14 positioned at the retreat limit, Moved forward. When the forward moving speed of the longitudinally moving body 14 becomes the same as that of the slats 22, the seal head 76 is lowered. When the seal head 76 is lowered to the lower limit, the seal head 76 is pressed against the mouth edge of the container C via the lid member F, and is moved to a position just before the forward limit in this state. During this time, the primary seal is performed. At the same time, the secondary sealing unit 18 performs secondary sealing, and the trimming unit 19 trims the lid material F.
[0031]
Immediately before the seal head 76 is lowered, both piston rods 83 and 84 of the positioning fluid pressure cylinder 82 are lowered, and the lower positioning rod 87 is inserted into the lower positioning hole 24. Thereby, positioning of the slat 22 and the seal head 76 is performed. In this case, if the lower positioning hole 24 and the lower positioning rod 87 are eccentric, the lower positioning rod 87 is lowered while the tip tapered portion thereof is aligned with the opening edge portion of the lower positioning hole 24, so that the eccentricity is separated. Only the unit mounting plate 72 is swung, and both are concentric.
[0032]
The forward and backward moving body 14 has a forward distance shorter than a distance corresponding to two pitches of the slat 22 by a distance corresponding to a cycle of 90 ° / 360 °. When the front-rear moving body 14 is moved to a position before the forward limit, the seal head 76 is raised. Almost simultaneously with the raising of the seal head 76, both piston rods 83, 84 of the positioning fluid pressure cylinder 82 are raised. Then, the upper positioning rod 86 is inserted into the upper positioning hole 66. Thereby, the positioning of the longitudinally moving body 14 and the unit mounting plate 72 is performed, and thereby the swinging of the unit mounting plate 72 is restrained. When the longitudinal moving body 14 moves backward from the forward limit to the backward limit, one cycle is completed.
[0033]
When performing a normal sealing operation, the lock bolt 68 is tightened. When cleaning the lower surface of the seal head 76, etc., the lock bolt 68 is loosened. Then, the left and right moving body 16 can move freely. When the handle 62 is grasped and pulled, the unit suspension rail 61 comes out of the movable guide rail 44 and the seal head 76 is pulled out from the upper side of the slat 22 as shown by a chain line in FIG. Then, the cleaning of the lower surface of the seal head 76 can be easily performed without the slats 22 being in the way.
[0034]
【The invention's effect】
According to the present invention, since there is no fear that the center of the container held by the slat is shifted from the center of the seal head, there is no fear of poor sealing.
