Abstract

(57)【要約】 物体を収容する熱成形された陥凹部（２）を有している熱可塑性の容器シート（１）に熱封可能なカバーシート（３）を熱封する装置は引き込みローラ（１１）と，引き込みローラ（１１）に対して軸平行で引き込みローラ（１１）の外周に圧着される加熱される密封ロール（１２）とを有している。装置が停止したときにシート（１・３）の過熱を防止するために，密封ロール（１２）は対向ロールとして作用する引き込みローラから引き離される。更に装置が作業を再開し，密封ロール（１２）が当て付けられるときに，密封されたシート（１・３）に密封されていない箇所あるいはその他の密封に欠陥のある箇所が生じることを避けるために，密封ロール（１２）は引き込みローラ（１１）に対して調節され，既に密封されている密封端部範囲の密封が繰り返されるようにする。代替構成では，密封ロール（１２）が引き離されている状態で，引き込みローラ（１１）が停止中に搬送方向に対して逆方向に一定の角度だけ回動せしめられる。 (57) [Abstract] An apparatus for heat-sealing a heat-sealable cover sheet (3) on a thermoplastic container sheet (1) having a thermoformed recess (2) for containing an object is a drawing roller. (11) and a heated sealing roll (12) which is axially parallel to the drawing roller (11) and is pressed against the outer circumference of the drawing roller (11). In order to prevent the sheets (1.3) from overheating when the device is stopped, the sealing roll (12) is pulled away from the pull-in roller, which acts as a counter roll. Furthermore, in order to avoid the occurrence of unsealed or other defective seals in the sealed sheet (1, 3) when the device is restarted and the sealing roll (12) is applied. In addition, the sealing roll (12) is adjusted with respect to the draw-in roller (11) so that the sealing of the already sealed sealing end region is repeated. In an alternative configuration, with the sealing roll (12) being pulled apart, the pull-in roller (11) is rotated by a certain angle in the opposite direction to the transport direction while stopped.

Description

【発明の詳細な説明】 陥凹部型包装容器の密封装置 背景技術 本発明は，請求項１の上位概念部に記載したような，物体を収容する熱成形さ れた陥凹部を有している熱可塑性の容器シートに熱封可能なカバーシートを熱封 する装置に関する。このような形式の装置においては，故障によって装置が停止 した場合に，カバーシート及び容器シートの密封層が密封ロールの熱作用によっ てこれらのシートの接触範囲において過熱され，若しくは燃焼せしめられること を防止するために，上述の形式の公知の装置においては，密封ロールは作業位置 から安全位置に旋回せしめられて，カバーシートから引き離される。装置の作業 が再開される場合には，密封ロールは再び作業位置にもたらされて，引き込みロ ーラが再び駆動され，包装容器の搬送が再開される。しかし，陥凹部型の包装容 器は密封作業が中断されていたために，密封されていない汚れた箇所を有してい ることがある。このような包装容器は記録され，不良品として除去される。 発明の利点 請求項１の特徴を備えた本発明による熱封装置は，次のような利点を有してい る。すなわち作業中断の際 に密封ロールと接触していたカバーシート部分が二重に密封されることによって ，密封されていない汚れた箇所を有している包装容器が形成されることがなく， 包装容器を記録して除去する必要がない。 請求項２以下に記載した手段によって，請求項１に記載した熱封装置に更に改 良を加えることができる。請求項２の構成は特に簡単な機械的手段であって，特 に有利である。しかし請求項４の構成も簡単な制御技術原理に基づくものである 。 図面 本発明の２つの実施例が図面に示されており，以下において詳細に説明する。 図１は第１実施例のロール式熱封装置の作業状態における側面図，図２及び図３ は図１の熱封装置の安全状態及び作業再開状態における側面図，図４及び図５は 第２実施例のロール式熱封装置の作業状態及び安全状態における側面図である。 実施例の説明 熱可塑性のシート１に陥凹部２を熱形成し，陥凹部２に包装される物体を充て んする機械内に熱封装置が配置されており，この熱封装置は引き込みローラ１１ と，この引き込みローラの外周に圧着される加熱可能な密封ロール１２とを有し ている。シート１の陥凹部２を受容するポケット１３を外周に有している引き込 みローラ１１は回転軸受け１４によって水平に支承されており，作業中連続的に 駆動される。充てんされた 陥凹部２を有するシート１は水平な平面内で引き込みローラ１１に供給され，引 き込みローラ１１上でほぼ１００°の円弧に沿って下方に転向せしめられる。こ の円弧区間には上方から熱封可能なカバーシート３が供給され，このカバーシー トは密封ロール１２によってシート１に線状に圧着され，その場合熱及び圧力が 伝達されることによって，連続的な搬送中にシート１に密封される（図１，図４ ）。密封ロール１２は，装置の停止の際に密封ロール１２によって負荷されるカ バーシート３及びシート１の部分が過熱され，場合によっては燃焼することを防 止するために，引き込みローラ１１から引き離し可能に配置されており，装置が 停止したときに作業位置から安全位置（図２及び図５）にもたらされる。密封ロ ール１２はこのために旋回可能なレバーー１５に回転可能に支承されている。 更に，装置の停止が終了して，密封ロール１２の引き離しの際に丁度負荷され ていたカバーシート３の範囲が，密封ロール１２が再び当て付けられて密封が再 開される際に，欠陥なしに，密封されていない箇所が生じないように，密封され るようにするために，停止時間の開始の際に密封ロール１２又は引き込みローラ １１が一定の角度だけ調節され，作業再開の際に，密封ロール１２は，カバーシ ート３の，既に密封されている範囲に当て付けられ，この範囲に２回目の密封が 行われるようになっている。 図１から図３に示した実施例においては，このために，密封ロール１２を保持 しているレバー１５は支承軸１７の偏心ピン１６に支承されている。支承軸自体 は定置の支承台１８に支承されている。支承軸１７をアーム１９によって１／４ 〜１／２回転させると，引き込みローラ１１に対する偏心ピン１６の回転軸線の 位置が調節される。この調節は，密封ロール１２が密封作業の対向ロールとして 作用する引き込みローラ１１に再び当て付けられる場合に，負荷線が密封ロール １２の引き離しの前に既に密封されていた面の範囲内に，ａ＝５〜１０ｍｍの長 さだけ入り込んでいるように，行われる。これによって，密封が重ねて行われ， 作業再開範囲の均一な密封が保証される。引き続く作業中に，支承軸１７は再び ゆっくりと最初の位置に戻し回動せしめられ，したがって密封ロール１２は再び 正常な作業位置を占める。 図４及び図５に示した実施例では，密封ロール１２による密封範囲を重ならせ るために，引き込みローラ１１の駆動系又は伝動装置内に制御が行われて，５〜 １５°の角度αだけ引き込みローラ１１が戻し回動せしめられる（図５）。引き 込みローラ１１のこの戻し回動は，伝動装置又は駆動装置に戻し回動を重畳させ ることによって，行われる。装置の作業開始後，この戻し回動は再びゆっくりと ゼロに戻され，密封ロール１２は一定の時間後に再び正常な作業位置を占める。Detailed Description of the Invention                        Sealing device for recess type packaging container Background technology   The present invention is a thermoformed object containing object as described in the preamble of claim 1.
