Abstract

<P>PROBLEM TO BE SOLVED: To improve the flexibility of rotation control and space saving by driving a mandrel by a servo mechanism. <P>SOLUTION: In the mandrel for forming the bottom of a carton spread in a cylindrical form, a drive of rotation is made by servo drive. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

この発明は、筒状に開いた状態のカートンの底部を形成し、牛乳等に代表される飲料を充填するための装置に送り込むマンドレル装置に関するものである。  The present invention relates to a mandrel device that forms a bottom portion of a carton that is opened in a cylindrical shape and that is fed into a device for filling beverages typified by milk or the like.

収納部に収納された多数の重ねあわされたカートンを一方の端から一枚ずつピッキング部によりピッキングすると共に、カートンを開いて、底部をシールするためのマンドレル装置に送り込まれる。マンドレル装置は、回転しており、各位置で底部形成のための工程を行う。まず最初の位置では、受け取ったカートンの底部の折癖を付ける。さらに次の位置では底部を加熱した後で、底部を折り込み、最後に底部をプレスして底部形成が完成される。その後、充填装置に送り込まれて、牛乳に代表される飲料を充填する工程へと順次流れている。  A number of stacked cartons stored in the storage unit are picked one by one from one end by a picking unit, and the cartons are opened and fed into a mandrel device for sealing the bottom. The mandrel device is rotating and performs a process for forming the bottom at each position. In the first position, put a signature on the bottom of the received carton. Further, in the next position, after the bottom is heated, the bottom is folded, and finally the bottom is pressed to complete the bottom formation. After that, it is sent to a filling device and sequentially flows to a process of filling a beverage typified by milk.

従来このマンドレルはインデクサー機構により、ギヤを用いた間欠回転で駆動していた。この方法では回転制御の自由度がないことから、カートンの種類その他の変更を要するときに設定変更が煩雑であり、回転制御の自由度への要望があった。また、インデクサー機構ではどうしても大型のものになってしまい省スペース化が図れないという問題を有していた。  Conventionally, this mandrel is driven by an intermittent rotation using a gear by an indexer mechanism. In this method, since there is no degree of freedom in rotation control, setting changes are complicated when it is necessary to change the type of carton or the like, and there has been a demand for freedom in rotation control. In addition, the indexer mechanism has a problem that it is inevitably large and space saving cannot be achieved.

この発明は、サーボ機構によりマンドレルを駆動するようにしたために、回転制御の自由度を向上させることができるとともに、省スペース化が図れるようにするものである。  According to the present invention, since the mandrel is driven by the servo mechanism, the degree of freedom in rotation control can be improved and space saving can be achieved.

すなわち、本願発明のマンドレル装置は、牛乳などの飲料の紙パック充填装置であって、最初に紙パックの折り畳まれた状態のカートンが供給され、その後筒状に広げられたカートンの底部を形成するためのマンドレルにおいて、回転の駆動をサーボ駆動により行うことを特徴とするものである。  That is, the mandrel device of the present invention is a paper pack filling device for beverages such as milk, and is first supplied with the folded carton of the paper pack, and then forms the bottom of the carton that is expanded into a cylindrical shape. In the mandrel, the rotation is driven by servo drive.

本願発明に係るマンドレル装置によれば、サーボ機構により回転駆動を行うため、回転の制御が自由に行うことができ、カートンの種類など種々の条件変更により、回転速度を変更することが自由に行うことができる。また、サーボ機構により制御を可能としたので、従来のインデクサー機構のような大掛かりな装置を必要とせず、省スペース化が図れる。また、インフィード部からのカートンの送り込み時に対する動作タイミングの制御も可能となる。  According to the mandrel device of the present invention, since the rotation is driven by the servo mechanism, the rotation can be freely controlled, and the rotation speed can be freely changed by changing various conditions such as the type of carton. be able to. In addition, since the servo mechanism enables control, a large-scale device such as a conventional indexer mechanism is not required, and space can be saved. In addition, it is possible to control the operation timing when the carton is fed from the infeed unit.

以下、添付の図面に従って、この発明を詳細に説明する。図1は装置の概略図であり、マンドレル1が図では左回転をしている。折り畳まれたカートンが筒状に広げられ、その状態でマンドレル1に送り込まれてくる。そして、マンドレル1に備えられている各筒状ホルダー(図では8個)に外周円側が底部形成される向きでカートン挿入され、そのままの状態で回転して各工程を通る。このマンドレル1には、最初の工程である、ボトムフォルダ2と呼ばれる底部形成のための仮折工程がある。仮折工程を終えた後、次に、45度変更した位置にボトムヒーター3と呼ばれる底部の加熱装置を備えている。この加熱により、表面のポリエチレンが溶ける。次に90度程度移動した位置にはボトム折込機構4を備えており、ボトムが形作られる。さらに45度移動した位置にはボトムプレス5と呼ばれる工程がある。ボトムプレス工程では1ton程度の押圧で完全なる底部の接着を行う。その後、マンドレル部の筒状ホルダーから排出され、次の充填工程へと搬送される。  Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a schematic view of the apparatus, in which the mandrel 1 rotates counterclockwise. The folded carton is unrolled into a cylindrical shape and fed into the mandrel 1 in that state. Then, a carton is inserted into each cylindrical holder (eight in the figure) provided in the mandrel 1 in the direction in which the outer peripheral circular side is formed at the bottom, and the carton is rotated as it is to pass through each process. The mandrel 1 has a temporary folding process for forming a bottom part called a bottom folder 2 which is the first process. After finishing the temporary folding step, a bottom heating device called a bottom heater 3 is provided at a position changed by 45 degrees. This heating dissolves the polyethylene on the surface. Next, a bottom folding mechanism 4 is provided at a position moved about 90 degrees, and the bottom is formed. Furthermore, there is a process called bottom press 5 at a position moved 45 degrees. In the bottom press process, the bottom part is completely bonded by pressing about 1 ton. Then, it is discharged from the cylindrical holder of the mandrel part and conveyed to the next filling step.

当該マンドレル1のサーボ機構による回転速度と動作タイミングをカートン4の種類に応じて、過去のデータをもとに制御できるようになっている。  The rotation speed and operation timing by the servo mechanism of the mandrel 1 can be controlled based on past data according to the type of carton 4.
