本考案は、カートン容器のシール部分を溶着シールする
超音波シール装置の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an ultrasonic sealing device for welding and sealing the sealing portion of a carton container.
近年、ジュース、清酒等の浸透性の強い液体を対象にし

箔、ポリエチレンの５層からなる材料を用いたカートン
容器が市場に出廻っているが、該材料のうち、内外面の
ポリエチレンは、サーモプラスチック材料で、十分溶融
する熱を加えられ、その後冷却されることによって溶着
する性質をもっており、このようなカートン容器のシー
ル部分の溶着シールには第１図に示すような超音波シー
ル装置が用いられている。In recent years, carton containers made of five layers of polyethylene, paperboard, polyethylene, aluminum foil, and polyethylene have appeared on the market for highly permeable liquids such as juice and sake. Among the materials, the polyethylene on the inner and outer surfaces is a thermoplastic material that has the property of being welded by applying sufficient heat to melt it and then cooling it. An ultrasonic sealing device as shown in the figure is used.
第１図において、１は振動ホーンで、その先端部にはカ
ートン容器との接触面２が形成され、超音波振動子３に
連結されており、該超音波振動子３により約２００００
ヘルツの周波数で振動されるようになっている。In FIG. 1, reference numeral 1 denotes a vibrating horn, the tip of which has a contact surface 2 with the carton container, and is connected to an ultrasonic vibrator 3.
It vibrates at a frequency of Hertz.
４はアンビルで、その先端部にはカートン容器との接触
面５が形成され、エアシリンダ６により矢印１７方向へ
移動されるようになっている。Reference numeral 4 denotes an anvil, the tip of which has a contact surface 5 with the carton container, and is moved in the direction of arrow 17 by an air cylinder 6.
超音波振動子３及びエアシリンダ６は図示されていない

をかけてはさみ込み、ついて、振動ホーン１が超音波振
動子３によって所要時間振動し、シール部分１２のポリ
エチレンを溶融する。The ultrasonic vibrator 3 and the air cylinder 6 are attached to the main body (not shown), and are filled with liquid by a pair of chain conveyors 9 and 10 having carton container holding frames 7 and 8, and are filled with liquid at the closed end portion. When the carton container 11 in which the carton container 11 is enclosed is sent to a predetermined position, the air cylinder 6 is activated by a command from a control device (not shown), and the seal portion 12 of the carton container 11 is moved to a predetermined position by the vibrating horn 1.
An appropriate pressure is applied between the contact surface 2 of the anvil 4 and the contact surface 5 of the anvil 4, and the vibrating horn 1 is vibrated for a required time by the ultrasonic vibrator 3 to melt the polyethylene of the seal portion 12.
振動ホーン１は所要時間振動した後停止するが、上記し
た圧力で７１シ一ル部分１２を所要時間はさみこんだま
まにしノておくと、溶融したポリエチレンは冷却硬化し
、溶着シールされる。The vibrating horn 1 vibrates for a required time and then stops, but if the 71 seal portion 12 is left sandwiched under the above pressure for a required time, the molten polyethylene is cooled and hardened, and is welded and sealed.
そして溶着シールが終了すると、アンビル４はエアシリ
ンダ６の作動により後退させられ、続いてカートン容器
１１は次工程へ送られる。When the welding and sealing is completed, the anvil 4 is moved back by the operation of the air cylinder 6, and the carton container 11 is then sent to the next process.
なお、上記構成においては、アンビル４を移動できるよ
うにしているが、振動ホーン１を移動するようにしても
よく、又、両方を移動するようにしてもよい。In the above configuration, the anvil 4 is movable, but the vibrating horn 1 or both may be movable.
以上のような超音波シール装置においては、従来、第２

ることが知られている。In the ultrasonic sealing device as described above, conventionally, the second
As shown in FIG. 3, the seal portion 12 of the carton container 11 is attached to the contact surface of at least one of the contact surface 2 of the vibrating horn 1 or the contact surface 5 of the anvil 4 (in this example, the contact surface 5 of the anvil 4). It is known that recesses 5a and 5b are provided to accommodate variations in thickness, and the entire surface of the seal portion 12 is equally pressurized so that the amount of heat generated when subjected to ultrasonic vibration is the same.
これは、この種のカートン容器１１は成形時第２図に示

とが生じて、肉厚が変動し、例えばＡ部分が丁度良好な
シール状態となるように圧力をかけてはさむと、Ｂ部分
及びＣ部分は過度の熱エネルギーを受けて焦げが発生す
るので、これを防止するためである。This is because when this type of carton container 11 is molded, a flap 13 is folded into the inner surface of the panel and welded and sealed, as shown in FIG. Then, as shown in Figure 2, there will be a 4-ply part A, a 6-ply part B, and a 5-ply part C.
This causes the wall thickness to fluctuate. For example, if pressure is applied to the A section to ensure a good seal, the B and C sections will receive excessive heat energy and become scorched. This is to prevent this.
しかし、上記したように振動ホーン又はアンビルの接触

きを生じる。However, as described above, even if a recess is provided in the contact surface of the vibrating horn or the anvil to receive the same heat generation effect, the chain conveyor 9, 1 that transfers the carton container 11
As shown in FIG. 4, due to the extension of 0, etc., a variation of Δl (usually delayed by Δl) occurs with respect to the stop position 14 at the predetermined welding seal position of the transported carton container 11. .
前記した接触面の凹部５ａ、５ｂは、通常幅りに対して

、溶融したポリエチレンが完全にこの隙間を埋めること
ができずシール不良の原因となっていた。The above-mentioned recesses 5a and 5b on the contact surface are set to have a slight margin on both sides of the normal width, but due to the above-mentioned variation in the stop position, the correspondence between the recesses and the carton container collapses. As a result, a gap was created in the thickness varying portion 15 of the seal portion 12 of the carton container 11, and during welding and sealing, the molten polyethylene could not completely fill this gap, causing a seal failure.
これは、肉厚変動部１５に折曲げ部があるため、折曲げ

めで、シール不良となって中味の液体が漏洩する問題点
があった。This is because the wall thickness varying portion 15 has a bent portion, which causes strain due to the bending, and when subjected to ultrasonic vibration, generates more heat than a portion without a bent portion, and as described above, the recessed portion If the correspondence relationship with the molten polyethylene is slightly disrupted, the molten polyethylene acts to fill the gap, but if the correspondence relationship becomes severely disrupted, the gap cannot be completely filled, resulting in a seal failure and the liquid inside. There was a problem with leakage.

ある。The present invention has been proposed in order to solve the above-mentioned problems, and includes an ultrasonic sealing device for welding and sealing a sealing portion of a carton container, the contact surface of at least one of an anvil or a horn corresponding to the sealing portion of the carton container. A recessed portion having an appropriate width and depth corresponding to variations in the wall thickness of the seal portion is provided, and the recessed portion has a stepped portion corresponding to the amount of variation in the stopping position of the transported carton container. The characteristics and purpose of this are:
The object of the present invention is to provide an ultrasonic sealing device that can reliably perform welding and sealing without causing sealing defects.

め尽すことができる。Since the present invention is configured as described above, even if there is a variation in the stopping position of the carton container at the welding seal position due to the length of the chain conveyor that conveys the carton container, it is possible to accommodate this variation amount. Due to the action of the stepped portion, the corresponding wall thickness varying portion of the seal portion of the carton container will receive slightly excessive heat, so the amount of molten polyethylene will increase, and the gap created at the wall thickness varying portion will be sufficiently filled. I can do it.
従ってシール不良を防止して、確実に溶着シールするこ
とができる。Therefore, sealing defects can be prevented and reliable welding and sealing can be achieved.
以下本考案の一実施例を第５図乃至第６図に基づいて説

Ｃが形成されている。21 is a vibration horn, 22 is a contact surface of the vibration horn 21, 2
3 is an anvil, 24 is a contact surface of the anvil 23, and the second contact surface 24 has a recess 24a and a recess 24b having a width L and a depth H corresponding to the variation in wall thickness of the sealing portion 26 of the carton container 25. Further, the recess 24a is provided with a variation amount △ of the stopping position of the carton container 25 being transferred.
A stepped portion 24 with a width L' and a height H' set corresponding to l.
C is formed.
なお、段差部Ｈ′の高さはＨ’＝、ｔｏ（ｔｏ ：カー
トン容器の厚さ）程度に設定される。Note that the height of the stepped portion H' is set to approximately H'=to (to: thickness of the carton container).

い。In the above configuration, the seal portion 26 of the carton container 25
When the correspondence relationship between the wall thickness varying portion of the anvil 23 and the recesses 24 a and 24 b provided in the contact surface 24 of the anvil 23 is normal, the wall thickness varying portion of the seal portion 26 corresponding to the stepped portion 246 is slightly Although excessive heat will be generated, H' of the stepped portion 24C is )('=-!-to to to), so it will not burn to the extent that it will cause problems as a welded seal.

ール不良を生じることがない。On the other hand, even if the stopping position of the carton container 25 at the welding seal position varies by Δl from the predetermined position due to the length of the chain conveyor that transfers the carton container, the stepped portion 24 corresponds to the amount of variation. Since the polyethylene is heated by the action of C, the amount of molten polyethylene increases and can sufficiently fill the gap in the wall thickness variation portion, so that sealing failure does not occur.
