屋根型紙容器用のブランクスでは、表面に熱シール性の熱可塑性表面層を有する帯状の紙材料がシート状紙片に裁断され、このシート状紙片の縦縁部が加熱して筒状に縦シールされて、平板状に折畳まれたブランクスが得られる。この縦シールは、上述の熱シール性表面層を適切に加熱し、シート状紙片の両縁部を重ねて押圧することによって、行われる。 In blanks for roof-type paper containers, a strip-shaped paper material having a heat-sealable thermoplastic surface layer on the surface is cut into sheet-like paper pieces, and the vertical edges of the sheet-like paper pieces are heated and vertically sealed in a cylindrical shape. Thus, blanks folded into a flat plate shape are obtained. This vertical sealing is performed by appropriately heating the above-described heat-sealable surface layer and pressing both edges of the sheet-shaped paper pieces in a stacked manner.

しかしながら、加熱手段により適切に加熱されてるように、制御することは、必ずしも容易ではない。熱シール表面層を有するシート状紙片は、通常の製造工程では、高速で搬送されるので、シート状紙片の縦縁部のみを必要且つ十分に、制御して加熱することが難しく、縦縁部の全体若しくは一部で、必要な熱を加熱できない場合や過剰に熱を加えて過熱する場合、縦シールが不良になり、縦シール不良のブランクスを用いて液体食品を充填すると、液漏れを起こす恐れがある。
縦シールの加熱条件は、単に、ホットエアー噴射手段、赤外線照射手段、火炎加熱手段などの出力(出力電力)のみならず、雰囲気温度、ブランクスの搬送速度、ブランクスの搬送角度若しくは加熱手段との距離などの種々のパラメーターがある。
However, it is not always easy to control so that it is appropriately heated by the heating means. Since the sheet-like paper piece having the heat-sealed surface layer is conveyed at a high speed in a normal manufacturing process, it is difficult to control and heat only the vertical edge of the sheet-like paper piece. If the necessary heat cannot be heated in whole or in part, or if excessive heat is applied and overheated, the vertical seal will be defective, and filling with liquid food using blanks with poor vertical seal will cause liquid leakage There is a fear.
The heating conditions for the vertical seal are not only the output (output power) of the hot air injection means, infrared irradiation means, flame heating means, etc., but also the ambient temperature, blanks transport speed, blanks transport angle, or distance to the heating means. There are various parameters such as

この発明は、加熱手段により適切に加熱されてるように、制御して、シート状紙片の縦縁部を必要且つ十分に加熱し、良好な縦シールを得て、液漏れの無い液体食品充填紙容器を得ることができる、紙容器用ブランクスの縦シール装置、紙容器用ブランクスの製造装置、及び紙容器用ブランクスの製造法を提供することを目的とする。 The present invention controls liquid food filling paper that is controlled so as to be appropriately heated by the heating means, and necessary and sufficiently heats the vertical edge of the sheet-like paper piece, obtains a good vertical seal, and does not leak. It is an object of the present invention to provide a vertical sealing apparatus for paper container blanks, a paper container blank manufacturing apparatus, and a paper container blank manufacturing method capable of obtaining a container.

加熱によって、縦シールされるべき両縦縁部の一方若しくは両方の表面において、熱シール性表面層が軟化・溶融する。この軟化・溶融によって、縦シールされるべき両縦縁部がヒートシール可能になる。
In the present invention, a sheet-like paper piece conveyed at high speed is heated by a heating means so that the heat-sealable surface layer is softened and melted on one or both surfaces of both vertical edges to be longitudinally sealed.
The heating method by the heating means includes heating by flame radiation, heating by hot air injection, heating by infrared irradiation, and the like, and can be appropriately selected and changed.

本発明では、シート状紙片を折目線に沿って平板状に折畳手段で折畳む。この折畳みによって、縦シールされるべき両縦縁部が近接若しくは重ねられるようになる。しかしながら、立体的な容器形状になるように、折目線に沿って折畳まれるのではなく、平板状に折られる。 In this invention, a sheet-like paper piece is folded by a folding means in flat form along a crease line. By this folding, both vertical edges to be vertically sealed are brought close to each other or overlapped. However, it is not folded along the fold line so as to have a three-dimensional container shape, but is folded into a flat plate shape.

本発明では、縦シールされる両縦縁部を重ね、既に加熱されているので、シール押圧手段で押圧して縦シールすることができる。この縦シールによって、平板状の紙容器用ブランクスを得ることができる。 In the present invention, since both vertical edge portions to be vertically sealed are overlapped and already heated, they can be pressed vertically by the seal pressing means and vertically sealed. With this vertical seal, flat paper container blanks can be obtained.

良好な縦シールのブランクスを得て、液漏れの無い液体食品充填紙容器を得るこことができる。
In the present invention, among the obtained blanks, blanks determined to be defective are removed from the conveyance line by the defective product removing means.
Good vertical seal blanks can be obtained, and a liquid food-filled paper container free from liquid leakage can be obtained.

本発明の特徴では、加熱手段の通過直後又は折畳手段の装入前の少なくとも1カ所の、好ましくは、加熱手段の通過直後と折畳手段の装入前との少なくとも2箇所の測定位置に設置され、縦シールされるべき加熱された縦縁部の表面の縦方向全長を相対的に走査して、少なくとも20測定点、好ましくは30以上の測定点での温度を非接触型温度計で測定する。
加熱手段の通過直後又は折畳手段の装入前の少なくとも1カ所の測定位置で、測定することで、被加熱対象の温度状況を適切に把握することができる。
好ましい態様において、加熱手段の通過直後と折畳手段の装入前との少なくとも2箇所の測定点で温度を測り、それぞれの温度を比較することができ、温度低下の程度を測定、分析することができる。
20測定点未満では、良好な温度プロフィールを得ることが難しく、より好ましくは30以上である。

Relatively scan the entire length of the heated vertical edge surface to be installed and longitudinally sealed and measure the temperature at at least 20 measurement points, preferably 30 or more, with a non-contact thermometer taking measurement.
By measuring at at least one measurement position immediately after passing the heating means or before inserting the folding means, it is possible to appropriately grasp the temperature condition of the object to be heated.
In a preferred embodiment, the temperature can be measured at at least two measurement points immediately after passing the heating means and before the folding means is inserted, and the respective temperatures can be compared, and the degree of temperature drop can be measured and analyzed. Can do.
If it is less than 20 measurement points, it is difficult to obtain a good temperature profile, and more preferably 30 or more.

本発明の特徴では、温度調整コントローラーにおいて、測定位置での測定点の測定温度から、ブランクスの測定位置の温度プロフィールを得、前もって設定された基準プロフィールと比較し、良否及び温度調整のパラメーターを判断して、パラメーターを送出する。
基準プロフィールの前もって設定され、それが記録保存されているので、良否の判断や、温度調整のパラメーターの変更の要否を即座に判断することができる。
In the feature of the present invention, the temperature adjustment controller obtains the temperature profile of the measurement position of the blanks from the measurement temperature of the measurement point at the measurement position, compares it with a preset reference profile, and determines the quality and temperature adjustment parameters. And send the parameters.
Since the reference profile is set in advance and recorded and stored, it is possible to immediately determine whether or not it is necessary to change the parameters for temperature adjustment.

コントローラー送信路によって、温度調整のパラメーターに基づいて、加熱手段の出力を調整する信号を加熱手段に送信するので、加熱エネルギーを調製し、温度を調整することができる。温度調整のパラメーターに基づいて、加熱手段を通過する加熱手段の搬送速度を調整する信号を搬送手段に送信するので、搬送速度を調整し、温度を上げるために、速度を緩めて加熱時間を長くし、温度を下げるために、速度を早めて加熱時間を短くすることができる。温度調整のパラメーターに基づいて、加熱手段の通過直後からシール押圧手段の装入直前までの雰囲気温度を調整する信号を空調設備に送信するので、加熱手段の通過直後からシール押圧手段の装入直前までの間で温度低下が大きい場合、雰囲気温度を高めに調整し、温度低下が少ない場合、雰囲気温度を低めに調整することもできる。
According to the feature of the present invention, a signal for adjusting the output of the heating unit is transmitted to the heating unit based on the temperature adjustment parameter, and a signal for adjusting the conveyance speed of the sheet-like paper piece passing through the heating unit is transmitted to the conveyance unit. And a controller transmission path for transmitting a signal for adjusting the atmospheric temperature from immediately after passing the heating means to immediately before loading the seal pressing means to the air conditioning equipment.
Since the controller transmission path transmits a signal for adjusting the output of the heating means to the heating means based on the temperature adjustment parameter, the heating energy can be adjusted and the temperature can be adjusted. Based on the temperature adjustment parameters, a signal for adjusting the conveyance speed of the heating means that passes through the heating means is sent to the conveyance means. Therefore, in order to adjust the conveyance speed and increase the temperature, the speed is decreased and the heating time is lengthened. In order to lower the temperature, the heating time can be shortened by increasing the speed. Based on the temperature adjustment parameters, a signal for adjusting the ambient temperature from immediately after passing the heating means to immediately before inserting the seal pressing means is sent to the air conditioning equipment, so immediately after passing the heating means and immediately before inserting the seal pressing means. In the case where the temperature drop is large, the ambient temperature can be adjusted to be higher, and if the temperature drop is small, the atmosphere temperature can be adjusted to be lower.
