Description

本発明は吸収性物品の製造方法に関し、詳しくは、所定の模様が所定部位に配置された吸収性物品を製造する方法に関するものである。   The present invention relates to a method for manufacturing an absorbent article, and more particularly to a method for manufacturing an absorbent article in which a predetermined pattern is arranged at a predetermined site.

従来、紙おむつなどの吸収性物品を製造する方法として、例えば特許文献1に記載されるように、液不透過性シートと吸収体形成用シートを貼り合せて連続する積層体を形成し、該積層体を一定間隔毎に切断して吸収性本体を得、該吸収性本体を外層シートの所定箇所に貼り付けて製品とする方法や、特許文献2に記載されるように、吸収体を一定間隔ごとに貼り付けた液透過性シートと、液不透過性シートを貼り合せて連続する積層体を形成し、該積層体を一定間隔毎に切断して製品とする方法が知られている。   Conventionally, as a method for producing an absorbent article such as a paper diaper, for example, as described in Patent Document 1, a liquid-impermeable sheet and an absorber-forming sheet are bonded to form a continuous laminate, and the laminate The body is cut at regular intervals to obtain an absorbent main body, and the absorbent main body is attached to a predetermined portion of the outer layer sheet to obtain a product, or as described in Patent Document 2, the absorbent body is spaced at regular intervals. A method is known in which a liquid-permeable sheet and a liquid-impermeable sheet attached to each other are bonded together to form a continuous laminate, and the laminate is cut at regular intervals to obtain a product.

液不透過性シートは吸収性物品の非肌当接面側に配されるもので、この液不透過性シートには、製品着用時に吸収体を着用者の所定箇所に位置させるための所定の模様が印刷されており、例えば紙おむつにおいては前記模様が後身頃に配置され、その模様が着用者の背面側に位置するよう着用することで、吸収体が所定箇所に位置して吸収漏れなどが起こることなく適正な使用がなされるようになっている。   The liquid-impermeable sheet is disposed on the non-skin contact surface side of the absorbent article. The liquid-impermeable sheet has a predetermined structure for positioning the absorbent body at a predetermined position of the wearer when the product is worn. A pattern is printed, for example, in a paper diaper, the pattern is arranged on the back body, and by wearing the pattern so as to be located on the back side of the wearer, the absorbent body is positioned at a predetermined location and absorption leaks, etc. Appropriate use is made without happening.

すなわち、これら特許文献に記載の方法は、前記模様を、吸収性物品を製造する際に所定部位に配置しようとするもので、前記特許文献1では、連続部材(液不透過性シート)の切断長さよりも短いピッチで所定の模様を印刷し、該連続部材を伸張して繰り出すことで前記切断長さと印刷ピッチを一致させると共に、切断部材の位置に対し前記模様を配すべき位置と、搬送中の連続部材における模様の位置との差を演算し、該演算値に基づき、連続部材の繰り出し速度を制御して、前記模様が所定部位に位置するよう調整することが提案されている。   That is, the methods described in these patent documents attempt to arrange the pattern at a predetermined site when manufacturing an absorbent article. In Patent Document 1, the continuous member (liquid impermeable sheet) is cut. A predetermined pattern is printed at a pitch shorter than the length, and the continuous member is extended and fed out so that the cutting length and the printing pitch coincide with each other, and the position where the pattern should be arranged with respect to the position of the cutting member, and conveyance It has been proposed to calculate the difference between the position of the pattern in the continuous member in the middle and adjust the drawing speed of the continuous member based on the calculated value so that the pattern is positioned at a predetermined part.

また、特許文献2では、一定間隔毎に図柄(模様)が印刷された第2の層(液不透過性シート)の搬送途中部位に選択的に圧力を加えて図柄の印刷ピッチを調整すると共に、該第2の層と、吸収体が一定間隔毎に貼り付けられた第1の層(液透過性シート)とを貼り合せた後に、吸収体の位置と図柄の位置をそれぞれセンサーで検出し、その検出信号に基づいて第2の層の搬送速度を調整することで、前記模様が所定部位に位置するよう調整することが提案されている。   Further, in Patent Document 2, the print pitch of the design is adjusted by selectively applying pressure to a part of the second layer (liquid-impermeable sheet) on which the design (pattern) is printed at regular intervals. After the second layer and the first layer (liquid permeable sheet) on which the absorber is attached at regular intervals, the position of the absorber and the position of the pattern are detected by the sensors. It has been proposed to adjust the pattern so that the pattern is located at a predetermined site by adjusting the conveyance speed of the second layer based on the detection signal.

特開2001−29385号公報(図1参照)JP 2001-29385 A (see FIG. 1) 特表2002−512566号公報(図5参照)Japanese translation of PCT publication No. 2002-512566 (see FIG. 5)

しかし、特許文献1の方法では、搬送中の連続部材における模様の位置を該連続部材の繰り出し直後に検出しており、該検出位置から、連続部材と吸収体形成用シートの貼り合せ位置までの距離が長くなり、連続部材のテンション変動により模様の位置が搬送途中でずれる虞れがある。また、連続部材の繰出し速度の調整により位置修正を実施し、切断部材の位置と搬送中の連続部材における模様の位置を検出し、その検出結果と前記模様が配されるべき位置との差を演算し、その演算結果に基づき連続部材の繰出し速度を調整するので、結果として模様の位置調整に時間がかかり、部材の調整ロスも多くなるという問題が考えられる。   However, in the method of Patent Document 1, the position of the pattern on the continuous member being conveyed is detected immediately after the continuous member is fed out, and from the detection position to the bonding position of the continuous member and the absorber forming sheet. The distance becomes longer, and there is a possibility that the position of the pattern is shifted during the conveyance due to the tension variation of the continuous member. In addition, the position is corrected by adjusting the feeding speed of the continuous member, the position of the cutting member and the position of the pattern on the continuous member being conveyed are detected, and the difference between the detection result and the position where the pattern is to be placed is determined. Since the calculation is performed and the feeding speed of the continuous member is adjusted based on the calculation result, it takes time to adjust the position of the pattern, resulting in a problem that the adjustment loss of the member increases.

一方、特許文献2の方法では、搬送中の第2の層における図柄の位置検出、該図柄の印刷ピッチの調整、該第2の層の搬送速度の調整を、第2の層の繰出し直後に行っているため、貼り合せ位置までの距離が長くなって図柄の位置が途中でずれる虞れがある。したがって、図柄の位置調整に時間がかかったり、調整のための部材のロスも発生し易いという問題が考えられる。また、印刷ピッチを調整するための複雑な加圧手段と、図柄の位置を修正するための搬送速度調整手段を別々に備え、マーク検出器の信号と貼り合せ後の吸収体と図柄の位置ずれを検出し、その結果に基づき印刷ピッチの調整と図柄の位置修正を個別に調整するので、該方法を実施するための装置構成が複雑になるという問題がある。   On the other hand, in the method of Patent Document 2, the position detection of the symbol in the second layer being conveyed, the adjustment of the printing pitch of the symbol, and the adjustment of the conveyance speed of the second layer are performed immediately after the second layer is fed out. Since this is done, there is a possibility that the distance to the bonding position becomes long and the position of the symbol is shifted in the middle. Therefore, there may be a problem that it takes time to adjust the position of the symbol and a loss of a member for adjustment is likely to occur. In addition, a complicated pressurizing means for adjusting the printing pitch and a conveying speed adjusting means for correcting the position of the pattern are provided separately, and the signal of the mark detector and the positional deviation between the absorber after bonding and the pattern Is detected, and the adjustment of the print pitch and the correction of the position of the pattern are individually adjusted on the basis of the result.

本発明はこのような従来事情に鑑みてなされたもので、その目的とする処は、前記した従来の方法による問題点を解消し、所定の模様を所定の部位に精度良く配置することができ、且つ模様の位置修正を迅速に行うことができ、しかも簡単な装置構成で実施可能な吸収性物品の製造方法を提供することにある。   The present invention has been made in view of such conventional circumstances, and the object of the present invention is to eliminate the problems caused by the above-described conventional method and to accurately arrange a predetermined pattern at a predetermined site.

印刷ピッチPが前記切断長さLよりも長いと、模様の位置合せをするために第1基材シートの搬送速度を早くした際に該第1基材がたるんで蛇行や皺が入るため好ましくない。
また、印刷ピッチPは、前記切断長さLに対して、0.3%〜5%短いことが好ましい。
前記切断長さLに対する印刷ピッチPの短さの割合が0.3%未満では、模様の位置合せをするために第1基材シートの搬送速度を変動させた際、第1基材シートがたるむ虞れがあるため好ましくない。
前記切断長さLに対する印刷ピッチPの短さの割合が5%を越えると、第1基材シートの収縮力が強すぎた場合、吸収性物品に形成された後に皺が入ったり変形する虞れがあるため好ましくない。
When the printing pitch P is longer than the cutting length L, it is preferable because the first base material is slackened and wrinkled or wrinkled when the conveying speed of the first base material sheet is increased in order to align the pattern. Absent.
The printing pitch P is preferably 0.3% to 5% shorter than the cutting length L.
If the ratio of the short print pitch P to the cut length L is less than 0.3%, the first base sheet is changed when the conveyance speed of the first base sheet is changed in order to align the pattern. This is not preferable because there is a risk of sagging.
If the ratio of the printing pitch P to the cutting length L is less than 5%, if the shrinkage of the first base sheet is too strong, wrinkles or deformation may occur after it is formed on the absorbent article. This is not preferable.

第1基材シートに一定の印刷ピッチPをもって印刷される夫々の模様は、同一の図柄でも良いし、異なる複数種類の図柄が規則的に若しくは不規則的に配列するよう印刷されたものでも良い。
複数種類の図柄を印刷されている方が、多数の吸収性物品を包装袋に封入した際、各吸収性物品に夫々異なった図柄が施され、製品としてバラエティーに富むため好ましい。
Each pattern printed on the first base sheet with a constant printing pitch P may be the same pattern, or may be printed so that a plurality of different types of patterns are regularly or irregularly arranged. .
It is preferable that a plurality of types of designs are printed because, when a large number of absorbent articles are enclosed in a packaging bag, different designs are applied to the respective absorbent articles, and the products are rich in variety.

前記印刷ピッチPは、吸収性物品一組に対応する前記模様のピッチであり、各模様毎に前記印刷ピッチPの間隔でピッチの基準となる検知可能部分(模様の特定部分)を決めておくことが好ましい。さらに、前記模様に対応して、前記印刷ピッチPの間隔でピッチの基準となる検知可能なマークを、模様とは別に印刷しておくことが好ましい。
本発明において、ピッチ基準マークは、前記印刷ピッチPの基準となる模様の特定部分と、模様とは別に印刷されたマークの双方を含むものである。
The printing pitch P is the pitch of the pattern corresponding to a set of absorbent articles, and a detectable part (specific part of the pattern) serving as a reference for the pitch is determined for each pattern at intervals of the printing pitch P. It is preferable. Further, it is preferable to print a detectable mark which becomes a reference of the pitch at an interval of the printing pitch P, separately from the pattern, corresponding to the pattern.
In the present invention, the pitch reference mark includes both a specific portion of the pattern serving as a reference for the printing pitch P and a mark printed separately from the pattern.

前記模様やピッチ基準マークは、第1基材シートに予め印刷されていることが好ましいが、吸収性物品の製造工程上で印刷することもできる。
但し、吸収性物品の製造工程上で印刷を施す場合、印刷手段が別途必要になり装置が大型化し、大きな設備スペースが必要になると共に、異なる模様やピッチ基準マークを印刷することが困難になり汎用性が悪いため、予め模様やピッチ基準マークが印刷された第1基材シートを用いる方が好ましい。
第1基材に対する模様やピッチ基準マークの印刷方法としては、この種の吸収性物品において一般的に用いられるものであれば良く、例えば、グラビア印刷、フレキソ印刷、インクジェット印刷などをあげることができる。
The pattern and the pitch reference mark are preferably printed in advance on the first base sheet, but can also be printed in the manufacturing process of the absorbent article.
However, when printing is performed during the manufacturing process of absorbent articles, additional printing means are required, the apparatus becomes large, a large facility space is required, and it becomes difficult to print different patterns and pitch reference marks. Since the versatility is poor, it is preferable to use the first base sheet on which a pattern and a pitch reference mark are printed in advance.
As a printing method of the pattern or pitch reference mark on the first base material, any method generally used in this type of absorbent article may be used, and examples thereof include gravure printing, flexographic printing, and inkjet printing. .

模様やピッチ基準マークが予め印刷された第1基材シートを用いる場合、前記印刷ピッチPが0.1%〜5%伸張された状態で該第1基材シートをロール状に巻き取り、このロール状物を繰出し位置にセットし、繰出し装置で繰出すようにすることが好ましい。
該ロール状物に巻き取る際の印刷ピッチPの伸張割合が0.1%未満では、第1基材シートの巻取りが安定せず、蛇行して巻かれる虞れがあるため好ましくない、また、前記印刷ピッチPの伸張割合が5%を越えると、該ロール状物を吸収性物品の製造に供するまでに長期間保管した場合、伸張状態で長期間保たれるため第1基材シートが伸びきってしまう虞れがあり、模様を位置合せするための制御がし難くなるため好ましくない。
前記ロール状物に巻き取る際の印刷ピッチPの伸張割合は、0.3%〜3%であることがより好ましい。
When using the 1st base material sheet by which the pattern and the pitch reference mark were printed beforehand, the 1st base material sheet is rolled up in the state where the printing pitch P was extended 0.1%-5%, and this It is preferable to set the roll-like object at the feeding position and feed it with a feeding device.
If the elongation ratio of the printing pitch P when winding on the roll is less than 0.1%, the winding of the first base sheet is not stable and may be wound meandering, which is not preferable. When the stretch ratio of the printing pitch P exceeds 5%, the first base sheet is formed because the roll-like product is kept in a stretched state for a long period of time before being used for manufacturing an absorbent article. Since there is a possibility that the pattern will be stretched out, it becomes difficult to perform control for aligning the pattern.
The stretch ratio of the printing pitch P when winding on the roll is more preferably 0.3% to 3%.

本発明において、第1基材シートは前記したようにロール状物に巻き取られ、繰出し位置にセットして繰出し装置により連続的に繰出して搬送され、第2基材シートとの貼り合せ位置の手前で、その搬送速度を調整する調整手段を経て、第2基材シートとの貼り合せ位置に至る。   In the present invention, as described above, the first base sheet is wound around a roll-like material, set in the feed position, continuously fed out by the feeding device, and conveyed, and the first base sheet is bonded to the second base sheet. In front of this, it passes through an adjusting means for adjusting the conveying speed, and reaches the bonding position with the second base sheet.

第2基材シートは、第1基材シートとは別の繰出し位置にセットされ、別の繰出し装置により連続的に繰出して搬送され、前記貼り合せ位置に至る。
本発明において、第2基材シートは特に限定されるものではないが、例えば、この種の吸収性物品に用いられる吸収体形成用シートや、予め所定長さに切断されたパルプと吸収性樹脂からなる吸収体を所定間隔毎に貼り合わせた液通過性の表面材からなる長尺状のシートを挙げることができる。該長尺状シートには、弾性体とシートからなるギャザーなどが配置されていても良い。
また、第2基材シートとして複数の素材が積層されたシートを用いることもでき、それら複数の素材の貼り合せや、前記液通過性表面材への吸収体の貼り合せは、第1基材シートと第2基材シートの貼り合せ位置で同時に行うようにしても良い。
The second base sheet is set at a feeding position different from that of the first base sheet, and is continuously fed out and conveyed by another feeding device to reach the bonding position.
In the present invention, the second base sheet is not particularly limited. For example, an absorbent body forming sheet used for this type of absorbent article, or a pulp and absorbent resin that have been cut into a predetermined length in advance. An elongate sheet made of a liquid-permeable surface material in which an absorbent body made of the above is bonded at predetermined intervals can be exemplified. The elongated sheet may be provided with a gather made up of an elastic body and a sheet.
In addition, a sheet in which a plurality of materials are laminated can be used as the second substrate sheet. The bonding of the plurality of materials and the bonding of the absorbent body to the liquid-permeable surface material are performed using the first substrate. You may make it carry out simultaneously in the bonding position of a sheet | seat and a 2nd base material sheet.

第1基材シートと第2基材シートは、貼り合せ位置で貼り合されて連続する積層体となり、該積層体は切断位置に搬送され、所望の切断手段により、吸収性物品一個分の長さ(吸収性物品の長さL)で切断される。これにより得られた吸収性物品は、後の吸収性物品組立工程へと搬送される。   A 1st base material sheet and a 2nd base material sheet are bonded together in the bonding position, and become a continuous laminated body, this laminated body is conveyed to a cutting position, and is long for one absorbent article by a desired cutting means. It is cut by length (length L of the absorbent article). The absorbent article obtained by this is conveyed to the subsequent absorbent article assembly process.

第1基材シートの繰出し位置から貼り合せ位置までの間には、該第1基材シートにおける各模様の印刷ピッチP毎に配置されたピッチ基準マーク(模様の特定の位置または模様とは別に配したマーク)を検出するマーク検出手段が、少なくとも一箇所配置され、該マーク検出手段からの検出信号に基づき調整手段が作動して、第1基材シートの搬送速度が制御される。   Between the feeding position and the bonding position of the first base sheet, a pitch reference mark (apart from a specific position or pattern of the pattern) arranged for each printing pitch P of the pattern on the first base sheet. The mark detection means for detecting the arranged mark) is arranged at least at one place, and the adjustment means is operated based on the detection signal from the mark detection means to control the conveyance speed of the first base sheet.

マーク検出手段は特に限定されるものではなく、前記各模様やピッチ基準マークを検出すると検出信号を発するイメージセンサーやカラーセンサーなど、一般的に使われるマーク検出器が利用でき、印刷の有り無しや印刷色の変化を読み取れれば良いが、カラーセンサーが安価であるため好ましく用いることができる。   The mark detection means is not particularly limited, and a commonly used mark detector such as an image sensor or a color sensor that generates a detection signal when each pattern or pitch reference mark is detected can be used. It is only necessary to be able to read the change in print color, but it can be preferably used because the color sensor is inexpensive.

マーク検出手段は、貼り合せ位置と調整手段の間で、且つ貼り合せ位置の近傍にあることが好ましい。
マーク検出手段が第1基材シートの搬送経路における調整手段の前(上流側)にあると、調整手段により制御される前の印刷ピッチPが検出され、模様の位置ずれが正確に修正されたか否かが検出されないので好ましくない。
マーク検出手段が第1基材シートの搬送経路における調整手段の後(下流側)にあると、調整手段により制御された後の印刷ピッチPが検出され、模様の位置ずれが正確に修正されたか否かが検出できるため好ましい。
The mark detection means is preferably located between the bonding position and the adjusting means and in the vicinity of the bonding position.
If the mark detection means is in front (upstream side) of the adjustment means in the transport path of the first base sheet, the print pitch P before being controlled by the adjustment means has been detected, and the pattern positional deviation has been corrected correctly. Since it is not detected, it is not preferable.
If the mark detection means is behind (downstream) the adjustment means in the conveyance path of the first base sheet, the printing pitch P after being controlled by the adjustment means has been detected, and the pattern misalignment has been corrected correctly It is preferable because it can be detected.

調整手段は、第1基材シートの搬送経路における前記貼り合せ位置の前(上流側)で、且つ該貼り合せ位置近傍にあることが好ましい。詳しくは、調整手段と貼り合せ位置の間の距離が0.1m〜10mであることが好ましく、更に好ましくは5m以下の直近であることが良い。更に、貼り合せ位置直前の駆動ロールが回転速度を調整できる調整手段であることが好ましい。
すなわち、第1基材シートに印刷された各模様の位置を吸収性物品の所定部位に合せるべく、調整手段で第1基材シートの搬送速度を調整して前記模様の位置を修正するので、調整手段と貼り合せ位置の間の距離が短いほど好ましく、該距離が長いと、第1基材シートの伸縮などにより修正した模様の位置が変動し安定しない虞れがあるため好ましくない。
但し、第1基材シートを巻き取った前記ロール状物の大きさなどから、調整手段と貼り合せ位置間の距離を0.1m未満にする事は、実質的に困難である。
The adjusting means is preferably in front of (in the upstream of) the bonding position in the conveyance path of the first base sheet and in the vicinity of the bonding position. Specifically, the distance between the adjusting means and the bonding position is preferably 0.1 m to 10 m, and more preferably 5 m or less. Furthermore, it is preferable that the driving roll immediately before the bonding position is an adjusting means capable of adjusting the rotation speed.
That is, since the position of each pattern printed on the first base sheet is adjusted to the predetermined part of the absorbent article, the adjustment speed of the first base sheet is adjusted by the adjusting means to correct the position of the pattern. It is preferable that the distance between the adjusting means and the bonding position is as short as possible. If the distance is long, the position of the pattern corrected due to expansion and contraction of the first base sheet may fluctuate and may not be stable.
However, it is substantially difficult to make the distance between the adjusting means and the bonding position less than 0.1 m due to the size of the roll-like material around which the first base material sheet is wound.

調整手段としては、回転速度が加減速可能である少なくとも1つのロールを備えた手段が例示でき、前記マーク検出手段からの検出信号に基づき、該ロールの回転速度をサーボモーターなどにより変化させ、第1基材シートの搬送速度を加減速すると共に該第1基材シートを伸縮させて、前記ピッチ基準マークの切断基準位置(第1及び第2基材シートを貼り合せ所定長さに切断する際の基準位置)に対する位置を調整することにより、前記第1及び第2基材シートを貼り合せ切断する際の前記模様の位置を調整すると共に、前記印刷ピッチPを前記吸収性物品の切断長さと一致させ、前記吸収性物品の所定部位に前記所定の模様が位置するよう構成する。   Examples of the adjusting means include means provided with at least one roll whose rotational speed can be accelerated and decelerated. Based on the detection signal from the mark detecting means, the rotational speed of the roll is changed by a servo motor or the like, 1 The base sheet is accelerated and decelerated, and the first base sheet is expanded and contracted to cut the pitch reference mark cutting reference position (when the first and second base sheets are bonded and cut to a predetermined length). The position of the pattern when the first and second substrate sheets are bonded and cut is adjusted by adjusting the position relative to the reference position), and the printing pitch P is set to the cutting length of the absorbent article. The predetermined pattern is positioned at a predetermined portion of the absorbent article.

すなわち、ピッチ基準マークの位置がずれて模様を早く送る必要がある場合は、調整手段によって第1基材シートの搬送速度を速くし、ピッチ基準マークの位置を修正すると共に、調整手段と貼り合せ位置の間で第1基材シートを収縮させ印刷ピッチPを短くして、そのずれを修正し得るよう構成されている。
また、ピッチ基準マークの位置がずれて模様を遅らせる必要がある場合は、調整手段によって第1基材シートの搬送速度を遅くし、ピッチ基準マークの位置を修正すると共に、調整手段と貼り合せ位置の間で第1基材シートを伸張させ印刷ピッチPを長くして、そのずれを修正し得るよう構成されている。
また、印刷ピッチPは切断長さより予め短く設定してあるので、調整手段は、貼り合せ位置で第1及び第2基材シートを貼り合せた積層体を切断位置へ搬送する搬送速度に対し、第1基材シートを低速で送り出すことで、第1基材シートを伸張させて該第1基材シートと前記第2基材シートを貼り合せ切断する際の前記模様の印刷ピッチPを前記吸収性物品の切断長さと一致させ得るよう構成されている。
That is, when the position of the pitch reference mark is shifted and the pattern needs to be sent quickly, the conveying speed of the first base sheet is increased by the adjusting means, the position of the pitch reference mark is corrected, and the adjusting means is bonded. The first base sheet is contracted between the positions to shorten the printing pitch P, and the deviation can be corrected.
Further, when the position of the pitch reference mark is shifted and it is necessary to delay the pattern, the adjustment unit slows down the conveyance speed of the first base sheet, corrects the position of the pitch reference mark, and adjusts the position of the adjustment unit and the bonding position. The first base sheet is stretched between the two to increase the printing pitch P, and the deviation can be corrected.
In addition, since the printing pitch P is set in advance shorter than the cutting length, the adjusting unit is configured to transfer the laminated body in which the first and second substrate sheets are bonded at the bonding position to the cutting position. By sending out the first base sheet at a low speed, the first base sheet is stretched to absorb the print pitch P of the pattern when the first base sheet and the second base sheet are bonded and cut. It is comprised so that it may be made to correspond with the cutting length of a property article.

前記したピッチ基準マークのずれの修正は、マーク検出手段により検出された第1基材シート搬送中の模様の位置と、吸収性物品の所定部位に該模様を配置するために予め決められた模様の位置との差を算出し、該算出値に基づき、調整手段のロールの回転速度を加減速することにより実施するのが好ましい。   The correction of the shift of the pitch reference mark described above is a pattern determined in advance for arranging the pattern at a predetermined position of the absorbent article and the position of the pattern during conveyance of the first base sheet detected by the mark detection means. It is preferable to carry out by calculating the difference from the position of and adjusting the rotation speed of the roll of the adjusting means based on the calculated value.

すなわち、第1基材シートの搬送中に、ピッチ基準マーク(模様の特定部分又は模様とは別に印刷されたマーク)がマーク検出手段で検出されるタイミングが、予め決められたタイミング(吸収性物品の所定部位に該模様を配置するためにピッチ基準マークがマーク検出手段で検出されるべきタイミング)よりも遅い場合、第1基材シートの搬送速度を速くすることで、ピッチ基準マークの位置を修正すると共に、調整手段と貼り合せ位置の間で第1基材シートが収縮し印刷ピッチPが短くなるよう修正され、吸収性物品の所定部位に模様が配置される。   That is, during the conveyance of the first base sheet, a timing at which a pitch reference mark (a specific portion of the pattern or a mark printed separately from the pattern) is detected by the mark detection means is a predetermined timing (absorbent article). If the pitch reference mark is later than the timing at which the mark detection means is to detect the pitch in order to place the pattern at a predetermined part of the sheet, the position of the pitch reference mark is adjusted by increasing the conveyance speed of the first base sheet. At the same time, the first base sheet is contracted between the adjusting means and the bonding position so that the printing pitch P is shortened, and a pattern is arranged at a predetermined portion of the absorbent article.

第1基材シートの搬送中に、ピッチ基準マークがマーク検出手段で検出されるタイミングが、予め決められたタイミングよりも早い場合、第1基材シートの搬送速度を遅くすることで、ピッチ基準マークの位置を修正すると共に、調整手段と貼り合せ位置の間で第1基材シートが伸張し印刷ピッチPが長くなるよう修正され、吸収性物品の所定部位に模様が配置される。   When the timing at which the pitch reference mark is detected by the mark detection means is earlier than the predetermined timing during the conveyance of the first base sheet, the pitch reference mark is reduced by reducing the transport speed of the first base sheet. The position of the mark is corrected, and the first base sheet is extended between the adjusting means and the bonding position so that the printing pitch P becomes longer, and the pattern is arranged at a predetermined portion of the absorbent article.

前記予め決められたタイミングは、吸収性物品を所定長さLに切断する際に該吸収性物品の所定部位(切断位置から所定寸法離間した位置)にピッチ基準マークが配置されるようなタイミングを基準として設定することができ、例えば、吸収性物品を所定長さLに切断するための切断手段の位置(例えば、切断カッターの角度の検出手段)などを基準の信号として利用することができる。
また、印刷ピッチの距離を算出し、演算により前記予め決められたタイミングの設定に用いることも可能で、算出された印刷ピッチの値を調整プログラムに利用することもできる。
The predetermined timing is such that when the absorbent article is cut to a predetermined length L, a pitch reference mark is arranged at a predetermined portion (position separated from the cutting position by a predetermined dimension) of the absorbent article. For example, the position of a cutting means for cutting the absorbent article into a predetermined length L (for example, a means for detecting the angle of the cutting cutter) can be used as a reference signal.
It is also possible to calculate the print pitch distance and use it to set the predetermined timing by calculation, and the calculated print pitch value can be used in the adjustment program.

調整手段は、2本以上のロールで構成されることが望ましい。該ロールの回転速度の加減速が第1基材シートの搬送速度を正確に加減速し得るようにするため、少なくとも1本のロールは、第1基材シートを挟んでスリップしないように加圧するニップロールを備えることが好ましい。   The adjusting means is preferably composed of two or more rolls. In order to allow acceleration / deceleration of the rotation speed of the roll to accurately accelerate / decelerate the conveyance speed of the first base sheet, at least one roll is pressurized so as not to slip across the first base sheet. It is preferable to provide a nip roll.

通常、第1基材シートはホットメルトなどの接着剤を塗布された後第2基材シートと貼り合されるが、接着剤を塗布した後はニップすることができない。よって、調整手段と貼り合せ位置の距離を短くするには、接着剤の塗布後に、前記ニップロールを備えない調整用のロールがあると良い。
すなわち、最も好ましい調整手段は、第1基材シートの繰出し位置側に、ニップロールを備えた搬送速度調整用の駆動ロールが配置され、貼り合せ位置側に、ニップロールの無い搬送速度調整用駆動ロールが配置され、これら駆動ロールの間に接着剤塗布手段が配置されたものである。
Usually, the first base sheet is bonded to the second base sheet after an adhesive such as hot melt is applied, but cannot be nipped after the adhesive is applied. Therefore, in order to shorten the distance between the adjusting means and the bonding position, it is preferable to have an adjusting roll that does not include the nip roll after application of the adhesive.
That is, the most preferable adjusting means is that a driving roll for adjusting the conveying speed provided with a nip roll is arranged on the feeding position side of the first base sheet, and a driving roll for adjusting the conveying speed without the nip roll is arranged on the bonding position side. The adhesive application means is arranged between these drive rolls.

調整手段を構成する複数本のロールは、すべて同速回転するものでも良いし、段階的に回転速度が変化するものでも構わない。   The plurality of rolls constituting the adjusting means may all rotate at the same speed, or may change in rotational speed stepwise.

第1基材シートの繰出し位置と調整手段の間には、ダンサーロール等によるテンション検出手段を設け、該テンション検出手段からの検出信号に基づき、第1基材シートの搬送中のテンションが一定になる様、第1基材シートの繰出し速度を調整することが好ましい。
尚、第1基材シートの搬送中のテンションを制御しない場合、該テンションの変動により、繰出し時の第1基材シートにおける模様の印刷ピッチが大きく変動する虞れがあるため、前記テンションを所定の値に制御することが好ましく、該テンション制御のために第1基材シートの繰出し速度を調整可能とすることが好ましい。
A tension detecting means such as a dancer roll is provided between the feeding position of the first base sheet and the adjusting means. Based on the detection signal from the tension detecting means, the tension during conveyance of the first base sheet is constant. As such, it is preferable to adjust the feeding speed of the first base sheet.
In addition, when the tension during the conveyance of the first base sheet is not controlled, there is a possibility that the printing pitch of the pattern on the first base sheet at the time of feeding may vary greatly due to the fluctuation of the tension. It is preferable to control to the above value, and it is preferable that the feeding speed of the first base sheet can be adjusted for the tension control.

本発明において、第1及び第2基材シートを貼り合せてなる積層体は、前身頃と後身頃を別途固定した上で一定ピッチで切断することで展開型の紙おむつとしたり、或いは、一定ピッチで切断した上で外装部材と一体化してパンツ型の紙おむつとすることができる。   In the present invention, the laminate formed by laminating the first and second base sheets is an unfolded paper diaper by fixing the front body and the back body separately and then cutting at a constant pitch, or a constant pitch. After being cut in step 1, it can be integrated with the exterior member to form a pants-type paper diaper.

以下、図1〜図4を参照して、本発明に係る吸収性物品の製造方法をより具体的に説明するが、本発明は該実施例に限定されるものではない。   Hereinafter, although the manufacturing method of the absorbent article which concerns on this invention is demonstrated more concretely with reference to FIGS. 1-4, this invention is not limited to this Example.

印刷ピッチ6は、無張力状態の第1基材シート1における隣り合わせる模様6のピッチ、及びこの模様6に対応して設けられたピッチ基準マーク7間のピッチであり、吸収性物品5の切断長さLよりも短くなっている。
図2に示す第1基材シート1は、前記印刷ピッチPをもって、異なる二種類の模様6が交互に位置するよう印刷したものである。それ以外の構成は図1に示す第1基材シート1と同様のため、重複する説明は省略する。
本発明では、図1、図2に示すいずれの第1基材シート1を用いても良いし、異なる複数種の模様が前記印刷ピッチPをもって規則的に又は不規則的に位置するよう印刷された第1基材シート1を用いることもできる。
1 and 2 show an example of a pattern pattern printed on the first base sheet 1.
The first base sheet 1 is a long and extensible sheet made of a polyethylene film as a liquid impermeable sheet, and constitutes a back sheet that is the non-skin contact surface side of the absorbent article.
On the first base sheet 1 shown in FIG. 1, the same pattern 6 is printed with the print pitch P described above, and a pitch reference mark 7 for detecting the print pitch P is provided for each pattern 6. Correspondingly, printing is performed with the printing pitch P so as not to cover the pattern 6.
The printing pitch 6 is the pitch of the adjacent patterns 6 in the first base material sheet 1 in the tension-free state and the pitch between the pitch reference marks 7 provided corresponding to the patterns 6, and the absorbent article 5 is cut. It is shorter than the length L.
The first base sheet 1 shown in FIG. 2 is printed with the print pitch P so that two different patterns 6 are alternately positioned. Other configurations are the same as those of the first base sheet 1 shown in FIG.
In the present invention, any of the first base sheets 1 shown in FIGS. 1 and 2 may be used, and different types of patterns are printed so as to be regularly or irregularly positioned with the printing pitch P. The first base sheet 1 can also be used.

第2基材シート2は、別途所定長さに切断された吸収体3を、所定間隔毎に、液通過性シート4に配置して形成された連続体であり、液通過性シート4は、吸収性物品の肌接触面側である表面シートを構成する(図3、図4参照)。   The second base sheet 2 is a continuous body formed by disposing the absorbent body 3 separately cut to a predetermined length on the liquid-permeable sheet 4 at predetermined intervals. The liquid-permeable sheet 4 is: The surface sheet which is the skin contact surface side of an absorbent article is comprised (refer FIG. 3, FIG. 4).

図3には、本発明に係る吸収性物品の製造方法を実施する装置の模式図を示す。
この装置は、前記印刷ピッチPが0.1%〜5%伸張された状態で第1基材シート1を巻き取ったロール状物10を、繰出し位置aにセットして繰出し装置11で繰出すようにすると共に、繰出された第1基材シート1が、テンション検出手段としてのダンサーロール12、調整手段13の搬送速度調整用の駆動ロール14、ピッチ基準マーク7を検出するマーク検出手段としてのマーク検出器15などを経て貼り合せ位置bに至り、該貼り合せ位置bにて、別の繰出し位置から繰出された第2基材シート2と前記第1基材シート1を貼り合せて連続する積層体8を形成した後、該積層体8を次工程になる切断位置cに搬送し、該切断位置cで積層体8を一定間隔で切断して個々の吸収性物品5を製造するようになっている。
In FIG. 3, the schematic diagram of the apparatus which enforces the manufacturing method of the absorbent article which concerns on this invention is shown.
In this apparatus, the roll-like object 10 that has wound up the first base sheet 1 in a state where the printing pitch P is stretched by 0.1% to 5% is set at the feeding position a and fed out by the feeding apparatus 11. At the same time, the fed first base sheet 1 is a dancer roll 12 as a tension detecting means, a driving roll 14 for adjusting the conveying speed of the adjusting means 13, and a mark detecting means for detecting the pitch reference mark 7. A mark detector 15 or the like is used to reach a bonding position b. At the bonding position b, the second base material sheet 2 fed from another feeding position and the first base material sheet 1 are stuck together to be continuous. After the laminated body 8 is formed, the laminated body 8 is transported to a cutting position c, which is the next process, and the laminated body 8 is cut at regular intervals at the cutting position c to produce individual absorbent articles 5. It has become.

貼り合せ位置bには上下一対のベルトコンベヤ16、17が設置され、第1基材シート1と第2基材シート2を貼り合せて連続する積層体8を形成し、該積層体8を切断位置cに搬送するようになっている。   A pair of upper and lower belt conveyors 16 and 17 are installed at the bonding position b, and the first base sheet 1 and the second base sheet 2 are bonded to form a continuous laminated body 8, and the laminated body 8 is cut. The sheet is conveyed to position c.

貼り合せ位置bの手前には、前記上下のベルトコンベヤ16、17間に吸収体3を所定速度で送り込むベルトコンベヤ18が設置され、所定間隔毎に吸収体3を備えた第2基材シート2が貼り合せ位置bに供給されるようになっている。   A belt conveyor 18 for feeding the absorbent body 3 at a predetermined speed is installed between the upper and lower belt conveyors 16 and 17 before the bonding position b, and the second base sheet 2 provided with the absorbent body 3 at predetermined intervals. Is supplied to the bonding position b.

前記駆動ロール14はニップロール14’を備えており、前記積層体8を切断位置cへ搬送する搬送速度に対し、第1基材シート1の速度を調整できるように構成されている。また、印刷ピッチPが吸収性物品の切断長さLより短く設定された第1基材シート1を、前記搬送速度より低速で貼り合せ位置bへ送り出すことで、第1基材シート1を伸張させて第2基材シート2と貼り合せ切断する際の前記模様6の印刷ピッチPを、吸収性物品5の切断長さLと一致させることができるように構成されている。   The drive roll 14 includes a nip roll 14 ′, and is configured so that the speed of the first base sheet 1 can be adjusted with respect to the transport speed for transporting the laminate 8 to the cutting position c. Moreover, the 1st base material sheet 1 extended | stretched by sending out the 1st base material sheet 1 in which the printing pitch P was set shorter than the cutting length L of an absorbent article to the bonding position b at a low speed from the said conveyance speed. Thus, the printing pitch P of the pattern 6 at the time of bonding and cutting to the second base material sheet 2 can be made to coincide with the cutting length L of the absorbent article 5.

また、駆動ロール14は、マーク検出器15によるピッチ基準マーク7の検出信号に基づきその回転速度が加減速され、吸収性物品5に対する模様6の位置がずれた場合、第1基材シート1の搬送速度が加減速され、吸収性物品5におけるピッチ基準マーク7の位置を修正することができるように構成されている。   Further, when the rotational speed of the drive roll 14 is accelerated or decelerated based on the detection signal of the pitch reference mark 7 by the mark detector 15 and the position of the pattern 6 with respect to the absorbent article 5 is displaced, The conveyance speed is accelerated and decelerated, and the position of the pitch reference mark 7 in the absorbent article 5 can be corrected.

切断位置cには、前記カッターロールの切断カッターの角度を検出する検出器21が設けられ、該検出器21で検出した切断カッターの位置検出信号を基準とし、予め決められたタイミング(吸収性物品5の所定部位に模様6を配置するためにピッチ基準マーク7がマーク検出器15で検出されるべきタイミング)を設定し、ピッチ基準マーク7がマーク検出器15で検出されたタイミングが、その予め決められたタイミングより遅い又は早い場合、第1基材シート1の搬送速度が加減速され、模様6の位置ずれ(吸収性物品5におけるピッチ基準マーク7の位置ずれ)を修正して、吸収性物品5の所定部位に模様6が配されるようになっている。   The cutting position c is provided with a detector 21 for detecting the angle of the cutting cutter of the cutter roll, and a predetermined timing (absorbent article) based on the position detection signal of the cutting cutter detected by the detector 21. The timing at which the pitch reference mark 7 is to be detected by the mark detector 15 in order to place the pattern 6 at the predetermined portion 5 is set, and the timing at which the pitch reference mark 7 is detected by the mark detector 15 is set in advance. If it is later or faster than the determined timing, the conveyance speed of the first base material sheet 1 is accelerated and decelerated, and the pattern 6 misalignment (position misalignment of the pitch reference mark 7 in the absorbent article 5) is corrected to absorb. A pattern 6 is arranged at a predetermined portion of the article 5.

駆動ロール14の加減速により生じた第1基材シート1のテンションの変動はダンサーロール12で検知され、その検出信号に基づき、繰出し装置11の駆動ロール19の回転速度が加減速され、第1基材シート1のテンションを所定値に調整し得るようになっている。   The fluctuation of the tension of the first base sheet 1 caused by the acceleration / deceleration of the drive roll 14 is detected by the dancer roll 12, and based on the detection signal, the rotation speed of the drive roll 19 of the feeding device 11 is accelerated / decelerated. The tension of the base sheet 1 can be adjusted to a predetermined value.

このような構成になる図示例の装置によれば、吸収体3を所定間隔毎に備えた第2基材シート2は、所定の一定速度で搬送され、貼り合せ位置bで第1基材シート1と貼り合せた後、切断手段20により、吸収体3が所定箇所に配されるよう、所定の位置で所定長さLをもって切断される。第2基材シートの切断位置の調整は、切断手段20により所定の一定速度で積層体8を切断しつつ、吸収体3の供給タイミングを調整する方法等により実施することができる。
また、第1基材シート1は、繰出し装置11、駆動ロール14により、印刷ピッチPが伸張された状態で貼り合せ位置bに供給され、第2基材シート2に貼り合される。
According to the apparatus of the illustrated example having such a configuration, the second base sheet 2 provided with the absorbent bodies 3 at predetermined intervals is conveyed at a predetermined constant speed, and the first base sheet at the bonding position b. After being bonded to 1, the cutting means 20 cuts the absorbent body 3 at a predetermined position with a predetermined length L so that the absorber 3 is disposed at a predetermined position. Adjustment of the cutting position of the second base sheet can be performed by a method of adjusting the supply timing of the absorbent body 3 while cutting the laminated body 8 at a predetermined constant speed by the cutting means 20.
Further, the first base sheet 1 is supplied to the bonding position b with the printing pitch P extended by the feeding device 11 and the driving roll 14, and is bonded to the second base sheet 2.

検出器21が検出した切断カッターの位置検出信号と、マーク検出器15が検出したピッチ基準マーク7の検出信号のタイミングがずれた場合、駆動ロール14が加減速されて第1基材シート1の搬送速度が調整され、模様6の位置ずれを修正して吸収性物品5の所定部位に模様6が配される。
また、前記加減速により生じた第1基材シート1のテンション変動は、ダンサーロール12からの検出信号に基づき駆動ロール19の加減速により調整され、テンションが所定値に保たれる。
When the timing of the position detection signal of the cutting cutter detected by the detector 21 and the detection signal of the pitch reference mark 7 detected by the mark detector 15 are deviated, the drive roll 14 is accelerated and decelerated, and the first base sheet 1 is detected. The conveyance speed is adjusted, the positional deviation of the pattern 6 is corrected, and the pattern 6 is arranged at a predetermined portion of the absorbent article 5.
The tension fluctuation of the first base sheet 1 caused by the acceleration / deceleration is adjusted by the acceleration / deceleration of the drive roll 19 based on the detection signal from the dancer roll 12, and the tension is maintained at a predetermined value.

このようにして搬送速度とテンションが適時に調整されながら搬送される第1基材シート1と、これとは別に搬送される第2基材シートとは、その後の切断長さLと模様6の印刷ピッチPが一致した状態で貼り合され、切断手段20で所定の長さLに切断され、個々の吸収性物品5となる。
得られた吸収性物品5には、所定部位に模様6が配されており、ベルトコンベヤ22で別の組立工程に送られ、紙おむつなどの製品に組み立てられる。
Thus, the 1st base material sheet 1 conveyed while adjusting conveyance speed and tension timely, and the 2nd base material sheet conveyed separately from this are the cutting length L and pattern 6 after that. Bonding is performed in a state in which the printing pitches P are matched, and the cutting means 20 cuts them to a predetermined length L, whereby individual absorbent articles 5 are obtained.
The obtained absorbent article 5 is provided with a pattern 6 at a predetermined site, and is sent to another assembly process by the belt conveyor 22 to be assembled into a product such as a paper diaper.

図4には、前述した装置における調整手段13が2本の駆動ロール14a、14bで構成されると共に、両駆動ロール14a、14bの間に、第1基材シート1への接着剤塗布手段としての接着剤塗布装置23が配設された例を示す。
第1基材シート1の繰出し位置a側に配置される駆動ロール14aはニップロール14cを有し、貼り合せ位置b側に配置される駆動ロール14bはニップロールの無いロールであり、これら駆動ロール14a、14bの間に接着剤塗布装置23を配置することで、第2基材シートとの貼り合せのためにホットメルトなどの接着剤を塗布された第1基材シート1に対しても、前述したように模様6の位置ずれを修正して、吸収性物品5の所定部位に模様6が配されるようになっている。
それ以外の構成および作動は図3に示す例と同様のため、重複する説明は省略する。
In FIG. 4, the adjusting means 13 in the above-described apparatus is constituted by two drive rolls 14 a and 14 b, and as an adhesive application means to the first base sheet 1 between the two drive rolls 14 a and 14 b. An example in which the adhesive application device 23 is provided is shown.
