Description
本発明は、筒状ラベルをマンドレルに被せて開口させながら、筒状ラベルを下方に送出することで、マンドレルの下方を通過する被嵌対象に筒状ラベルを被嵌するラベル被嵌方法およびラベル被嵌装置に関する。
The present invention relates to a label fitting method and a label for fitting a cylindrical label to a fitting object passing under the mandrel by sending the cylindrical label downward while opening the cylindrical label over the mandrel. The present invention relates to a fitted device.
従来、飲料用容器等の被嵌対象にシュリンクフィルム等の筒状ラベルを被嵌するラベル被嵌方法として、筒状ラベルをマンドレルに被せて開口させながら、ショットローラを用いて筒状ラベルを下方に送出することで、マンドレルの下方を通過する被嵌対象に筒状ラベルを被嵌する所謂ショット式のラベル被嵌方法が知られている(例えば特許文献1を参照)。
Conventionally, as a label fitting method for fitting a cylindrical label such as a shrink film on an object to be fitted such as a beverage container, the cylindrical label is moved downward using a shot roller while opening the cylindrical label over the mandrel. A so-called shot-type label fitting method is known in which a cylindrical label is fitted to a fitting object that passes below the mandrel by sending the sheet to the mandrel (see, for example, Patent Document 1).
このようなショット式のラベル被嵌方法は、一般に、一定の剛性を有した厚さ40μm等の筒状ラベルを被嵌対象に被嵌する場合に採用され、厚さ20μm等の薄い筒状ラベルの場合には、筒状ラベルの柔軟性が高く、被嵌対象に良好に被嵌することが難しい。このため、筒状ラベルの複数箇所を外側から保持し、筒状ラベルを開口させつつ下方に移動させて被嵌対象に被嵌する等の別のラベル被嵌方法が採用されていた。
Such a shot-type label fitting method is generally employed when a cylindrical label having a certain rigidity, such as a thickness of 40 μm, is fitted on a target to be fitted, and a thin cylindrical label, such as a thickness of 20 μm. In this case, the flexibility of the cylindrical label is high, and it is difficult to fit the fitting target well. For this reason, other label fitting methods, such as holding a plurality of places of a cylindrical label from the outside, moving it downward while opening the cylindrical label, and fitting it on a fitting target, have been adopted.
しかしながら、ショット式のラベル被嵌方法は、コスト面や設備面で有利であることから、20μm等の薄い筒状ラベルについても、ショット式のラベル被嵌方法によって筒状ラベルを被嵌対象に被嵌することが要望されている。
However, since the shot-type label fitting method is advantageous in terms of cost and equipment, even for thin cylindrical labels such as 20 μm, the cylindrical label is covered on the object to be fitted by the shot-type label fitting method. It is desired to fit.
そこで、20μm等の薄い筒状ラベルの場合に、ショット式のラベル被嵌方法を採用することが難しい理由を以下に検討する。
Therefore, the reason why it is difficult to adopt the shot-type label fitting method in the case of a thin cylindrical label of 20 μm or the like will be examined below.
まず、20μm等の薄い筒状ラベルは、被嵌対象、例えば飲料用容器等のボトル容器への被嵌時に、ボトル容器の外面にまとわり付き易く、被嵌対象の底部まで届きにくく、また、ボトル容器の外面は、飲料等を充填、密封後、洗浄、ブロワーによる水滴除去が行われるが、外面に水滴が残存する場合があり、このウェット状態で筒状ラベルを被嵌しようとすると、筒状ラベルを10m/s程度の高速で送出する必要が生じる。
ところが、10m/s程度の高速で筒状ラベルを送出した場合、図5に示すように、ショットローラによって送出された筒状ラベルが空気抵抗を受けて変形を生じ、被嵌対象に対する筒状ラベルの被嵌不良が生じてしまうことがある。 First, a thin cylindrical label of 20 μm or the like is easy to cling to the outer surface of a bottle container when it is fitted to a fitting object, for example, a bottle container such as a beverage container, and difficult to reach the bottom of the fitting object. The outer surface of the bottle container is filled with a beverage, etc., sealed, washed, and water drops are removed by a blower.However, water drops may remain on the outer surface, and when trying to fit the cylindrical label in this wet state, It is necessary to send the cylindrical label at a high speed of about 10 m / s.
However, when the cylindrical label is sent out at a high speed of about 10 m / s, as shown in FIG. 5, the cylindrical label sent out by the shot roller is subjected to air resistance and is deformed, and the cylindrical label for the object to be fitted is formed. May cause poor fitting.

ここで、空気抵抗に起因して筒状ラベルの変形が生じる原因としては、20μm等の筒状ラベルは柔軟性が高いために、筒状ラベルに変形が生じ易いことに加えて、筒状ラベルの搬送時に不可避的に形成される折り目も、その一因であると考えられる。
Here, the cause of the deformation of the cylindrical label due to the air resistance is that the cylindrical label of 20 μm or the like is highly flexible, so that the cylindrical label is easily deformed, and the cylindrical label A crease that is inevitably formed during the conveyance of the sheet is also considered to be one of the causes.
具体的に説明すると、筒状ラベルを搬送する際には、筒状ラベルがシート状に折り畳まれた状態で搬送されるため、筒状ラベルには、合計2箇所の折り目が搬送方向に形成されることになる。
そして、筒状ラベルがマンドレルに被せられている時には、筒状ラベルが断面円形状を呈しているのに対して、筒状ラベルがマンドレルから空中に投げ出された時には、前記折り目に起因して筒状ラベルが断面舟形状に変形するため、この空中における筒状ラベルの変形が、空気抵抗に起因した筒状ラベルの変形を助長する一因だと考えられる。 Specifically, when transporting the cylindrical label, the cylindrical label is transported in a state of being folded into a sheet, so that the tubular label has a total of two folds formed in the transport direction. Will be.
When the cylindrical label is put on the mandrel, the cylindrical label has a circular cross section. On the other hand, when the cylindrical label is thrown into the air from the mandrel, the cylinder is caused by the fold. It is considered that the deformation of the cylindrical label in the air is one factor for promoting the deformation of the cylindrical label due to the air resistance.

It is considered that the deformation of the cylindrical label in the air is one factor for promoting the deformation of the cylindrical label due to the air resistance.
そこで、上述した空気抵抗に起因した筒状ラベルの変形を抑制する案の1つとして、対向配置されたローラによって筒状ラベルの折り目を挟み込んで押圧することで、折り目を解消することが考えられるが、筒状ラベルの折り目は、搬送ローラによって筒状ラベルが繰り返し挟まれることによって形成されたものであることから、筒状ラベルの折り目を良好に解消することは難しい。
Therefore, as one of the proposals for suppressing the deformation of the cylindrical label due to the above-described air resistance, it is conceivable to eliminate the fold by sandwiching and pressing the fold of the cylindrical label with the rollers arranged opposite to each other. However, since the fold of the cylindrical label is formed by repeatedly sandwiching the cylindrical label by the transport roller, it is difficult to satisfactorily eliminate the fold of the cylindrical label.
そこで、本発明は、これらの問題点を解決するものであり、空気抵抗に起因した筒状ラベルの変形を抑制し、被嵌対象に対する筒状ラベルの良好な被嵌を実現するラベル被嵌方法およびラベル被嵌装置を提供することを目的とするものである。

すなわち、筒状ラベルの折り目を6つ以上にして筒状ラベルの断面形状を円形状に近づけることにより、被嵌対象に対する筒状ラベルの被嵌時における、被嵌対象と筒状ラベルとの間の接触範囲を小さく抑えることが可能であるため、被嵌対象と筒状ラベルとの摩擦抵抗を軽減することができる。
また、マンドレルに被せられた時の筒状ラベルの形状から、マンドレルから空中に投げ出された時の筒状ラベルの形状への、形状変化を小さく抑えることが可能であるため、空気抵抗に起因した筒状ラベルの変形をより一層抑制することができる。 According to the first, second, and fourth aspects of the present invention, the folds along the label axis direction are additionally formed on the cylindrical label, so that the number of the folds of the cylindrical label is six or more, and then the vicinity of the lower end of the mandrel The cylindrical label is sent downward by the shot roller installed in the cylinder, thereby forming a crease along the label axis direction in the cylindrical label to improve the strength of the cylindrical label, and the cylinder caused by air resistance.
