Description

本発明は物品のトップ面をフィルム片で封止するシール機及びこれを用いた物品の開口部のシール方法に関する。 The present invention relates to a sealing machine for sealing a top surface of an article with a film piece and a method for sealing an opening of an article using the same.

物品の開口部のトップ面をシールする方法には、例えば図１２のようにしてカップめん等のトップ面をシールする方法(従来技術１)や、図１３のようにしてコーヒーフレッシュ等のトップ面をシールする方法(従来技術２)がある。
図１２(イ)は搬送バケットｂｇにカップめん等の容器Ｐを載せて進行するが、その上方に平行してフィルムＦＬが走っている。フィルムＦＬで容器Ｐの開口部を覆い、次にシーラＳＬでヒートシールし、その後、搬送バケットｂｇ及びヒートシールされた容器Ｐごとそのまま同図左方へ進行して抜き刃ＮＫでカットする方法である。出来上がった容器Ｐを裏面側から見ると図１２(ロ)のように容器のフランジＰＧにはみ出す格好でトップフィルムＴＦが現れている。
図１３(イ)はシーラＳＬでコーヒーフレッシュの容器Ｐの上面開口部にフィルムＦＬを当ててヒートシールし、その後、フィルムＦＬに容器Ｐをつけたまま次の打ち抜き工程へと進んで、該打ち抜き工程で抜き型の雄型ＮＹを雌型ＮＸへ向けて打ち抜き、フィルムをカットする方法である。出来上がった容器Ｐを裏面側から見ると図１３(ロ)のように容器のフランジＰＧの外周縁に一致するトップフィルムＴＦが現れている。
さらにトップシールする方法として容器をフィルム側へ持ち上げて容器開口部に蓋をしシールする方法も提案されている(特許文献１参照)。 As a method of sealing the top surface of the opening of the article, for example, a method of sealing the top surface of a cup noodle or the like (conventional technology 1) as shown in FIG. 12, or a top surface of coffee fresh or the like as shown in FIG. There is a method of sealing (prior art 2).
In FIG. 12 (a), a container P such as a cup noodle is placed on the transport bucket bg, and the film FL runs in parallel therewith. Covering the opening of the container P with the film FL, then heat-sealing with the sealer SL, and then proceeding to the left in the figure as it is together with the transport bucket bg and the heat-sealed container P and cutting with the punching blade NK is there. When the completed container P is viewed from the back side, the top film TF appears as if it protrudes from the flange PG of the container as shown in FIG.
FIG. 13 (a) shows a sealer SL where the film FL is applied to the top opening of the coffee fresh container P and heat-sealed, and then proceeds to the next punching process with the container P attached to the film FL. In this process, the male die NY is punched toward the female die NX, and the film is cut. When the completed container P is viewed from the back side, a top film TF that coincides with the outer peripheral edge of the flange PG of the container appears as shown in FIG.
Further, as a top sealing method, a method has been proposed in which the container is lifted to the film side and the container opening is covered and sealed (see Patent Document 1).

Small holes 93a are provided at two locations on the upper plate 93 of the arrow-shaped body, and two air cylinder bodies 42a are erected on the upper surface of the upper plate 93 and the respective rod portions are inserted into the small holes 93a. Both rods 42b project from the upper plate 93 so as to be able to move forward and backward in synchronization. At the lower end of the rod 42b, the shaft member 41 is connected to the rod 42b so as to hang down, and the horizontal board 40 is fixed horizontally to the lower end of the shaft member 41. The horizontal board 40 is a board body having a size equal to the size of the base table 62 in plan view, and a circular hole 40a that is slightly larger than the circular diameter portion of the opening 21 is formed on the board surface. The axial center passing through the through hole 62a, the through hole 61a of the substrate 61, and the opening 21 of the die cutter 2 and the axial center of the circular hole 40a coincide.
Then, the cutting auxiliary body 43 is fixed to the lower surface of the horizontal board 40. The cutting auxiliary body 43 is a flat plate body having a plan view size substantially the same as that of the die cutter 2, and the upper surface side opening 21 (the shape of a film piece 35) in which the blade portion 22 of the die cutter 2 is located at the center of the flat plate body. .) A slightly similar passage hole 43b is provided. The lower surface 43a of the cutting auxiliary body 43 is a smooth surface, and when the rod 42b is advanced by the operation of the air cylinder 42, the belt-like film 3 is sandwiched between the blade portion 22 as shown in FIG. Then, it can be cut into film pieces 35 of a size that closes the opening 83 of the article 8 in the same shape as the blade 22. When the rod 42b is retracted by the operation of the air cylinder 42, the cutting assisting body 43 is moved up to a position where it is lifted by a distance substantially equal to the distance from the belt-like film 3 to the die cutter 2 as shown in FIG.

シーラ５は、前記切断補助装置４と前記ダイカッタ２とで帯状フィルム３から切り離したフィルム片３５を、上から押してそのまま下降させ、該フィルム片３５で物品８の開口部８３を塞いで物品上面８２に熱シールする押圧シール部材である。
エアシリンダ５０が前記上板９３の下面側にシリンダ本体５０ａを下方に向けて取付けられる。そのロッド５０ｂは貫通孔６２ａ,基板６１の通孔６１ａ,ダイカッタ２の開孔２１の軸心と一致するように進退動自在に下降する。該ロッド５０ｂの下端にシーラ本体５１が垂下状態に固着され、シーラ５は帯状フィルム３の上方で前記開孔２１に対向し、ロッド５０ｂの進退動により上下動可能にして、ロッド５０ｂを伸長させ下動させると、シーラ下部５１が前記円孔４０ａ,通過孔４３ｂを貫通しさらに前記開孔２１内に進入してフィルム片３５を物品８の上面８２へ押圧する。そして、シーラ本体５１の下部５２は図示しない加熱手段によって加熱できる構成にあり、下部５２が加熱されることによって物品上面８２に押圧された前記フィルム片３５で開口部８３を塞いで熱シールできるようになっている。ここでは、図５のようにシーラ下部５２の下面外周部に面圧を出す凸部５２１をリング状に隆起形成し、図１０のごとくフィルム片３５の円形部分の外周縁寄りのリング状体域ＨＳが熱シールされる。突出部３５ａは熱シールされず、また突出部３５ａが物品８の曲面部８５の上方に配されるため、曲面部８５と突出部３５ａとの間に隙間εができる(図１１のｂ)。開封するため物品８からフィルム片３５を剥ぎ取るときは、この隙間εを利用して突出部３５ａを手で掴み容易に剥ぎ取ることができる。 The sealer 5 pushes the film piece 35 cut off from the belt-like film 3 by the cutting assisting device 4 and the die cutter 2 from above and lowers it as it is, and closes the opening 83 of the article 8 with the film piece 35 to close the article upper surface 82. It is a pressure seal member that heat seals.
The air cylinder 50 is attached to the lower surface side of the upper plate 93 with the cylinder body 50a facing downward. The rod 50b descends so as to be movable forward and backward so as to coincide with the axial center of the through hole 62a, the through hole 61a of the substrate 61, and the opening 21 of the die cutter 2. The sealer body 51 is fixed in a suspended state at the lower end of the rod 50b. The sealer 5 is opposed to the opening 21 above the belt-like film 3 and can be moved up and down by the forward and backward movement of the rod 50b to extend the rod 50b. When moved downward, the sealer lower part 51 passes through the circular hole 40 a and the passage hole 43 b and enters the opening 21 to press the film piece 35 against the upper surface 82 of the article 8. The lower part 52 of the sealer main body 51 can be heated by a heating means (not shown), and the lower part 52 is heated so that the film piece 35 pressed against the upper surface 82 of the article closes the opening 83 and can be heat-sealed. It has become. Here, as shown in FIG. 5, a convex portion 521 for projecting surface pressure on the outer peripheral portion of the lower surface of the sealer lower portion 52 is formed in a ring shape, and a ring-shaped body region near the outer peripheral edge of the circular portion of the film piece 35 as shown in FIG. HS is heat sealed. The protruding portion 35a is not heat-sealed, and the protruding portion 35a is disposed above the curved surface portion 85 of the article 8, so that a gap ε is formed between the curved surface portion 85 and the protruding portion 35a (b in FIG. 11). When the film piece 35 is peeled from the article 8 for opening, the protruding portion 35a can be grasped by hand using the gap ε and easily peeled off.

そして、受け治具１０に作業者が物品８を装着して手元の押しボタンスイッチを押すと、制御盤Ｇに組み込まれたシーケンス制御又はコンピュータ制御による以下の一連の動作工程を順次遂行し、物品８の開口部８３を封止するシール方法を実現する。すなわち、押しボタンスイッチが入ると、先ずエアシリンダ１５が作動し、そのロッド１５ｂが収縮して物品８が被着された受け治具１０が開孔２１の真下へ移動してこの位置で停止する(図２の鎖線)。その後、ロッド１０ｂが上昇し、受け治具１０の保持体１０ｃに装着した物品８の上面部が通孔６１ａ,貫通孔６２ａを貫通しダイカッタ２の開孔２１内に配設される(図５)。次に、エアシリンダ４２が作動しそのロッド４２ｂが伸び、図６のごとく切断補助体４３が下降して帯状フィルム３の図柄マーク３１を挟着カットしフィルム片３５として切り離す(抜き工程)。続いて、エアシリンダ５０が作動しそのロッド５０ｂが伸びることによって、図７のごとくシーラ５の下部５２が円孔４０ａ,通過孔４３ｂを通って開孔２１内に進入しフィルム片３５で開口部８３を塞ぐようにして物品８の上面８２に押圧し、加熱手段により下部５２が過熱されてさらに熱シールする(シール工程)。シール片による物品８の開口部８３への熱シールが完了する。この熱シールの完了後、前記各エアシリンダが作動して受け治具１０,切断補助体４３,シーラ本体下部５２はそれぞれ当初位置に戻る。受け治具１０に装着された物品８は、その開口部８３がフィルム片３５で封された所望の製品となって押しボタンスイッチＧ_１のある水平板１２の一側寄りへ戻る。またモータが作動してリールＲ_１から帯状フィルム３の所定長さ分を送り出し、且つ巻取器Ｒ_２が帯状フィルム３を所定長さ分を巻き取って、新たな図柄マーク３１を開孔２１の真上に配設する。
前記製品を受け治具１０から取外した後、新たな物品８を受け治具１０に装着し、また押しボタンスイッチを押せば上述と同じ動作を繰返し、製品が順次製造されていく。
尚、図８の符号６２１はベース台６２に起立するガイド用支柱、符号４０ｂは水平盤に設けられた案内孔で、前記ガイド用支柱６２１を挿通して水平盤４０の上下動を円滑にするものである。符号ｂ_１,ｎ_１は支柱９４を基板６１,上板９３に螺着固定するボルト,ナット、符号ｂ_２はベース台６２を基板６１に固定するボルトそ示す。 Then, when the operator puts the article 8 on the receiving jig 10 and presses the push button switch at hand, the following series of operation steps by sequence control or computer control incorporated in the control panel G are sequentially performed, A sealing method for sealing the eight openings 83 is realized. That is, when the push button switch is turned on, the air cylinder 15 is first actuated, the rod 15b contracts, and the receiving jig 10 to which the article 8 is attached moves directly below the opening 21 and stops at this position. (The chain line in FIG. 2). Thereafter, the rod 10b rises, and the upper surface portion of the article 8 attached to the holding body 10c of the receiving jig 10 passes through the through hole 61a and the through hole 62a and is disposed in the opening 21 of the die cutter 2 (FIG. 5). ). Next, the air cylinder 42 is actuated to extend the rod 42b, and the cutting assisting body 43 is lowered as shown in FIG. 6, and the design mark 31 of the belt-like film 3 is nipped and cut as a film piece 35 (extraction process). Subsequently, when the air cylinder 50 is activated and the rod 50b is extended, the lower part 52 of the sealer 5 enters the opening 21 through the circular hole 40a and the passage hole 43b as shown in FIG. 83 is pressed against the upper surface 82 of the article 8 so that the lower portion 52 is heated by the heating means and further heat-sealed (sealing process). The heat sealing to the opening 83 of the article 8 by the seal piece is completed. After the heat sealing is completed, the air cylinders are operated to return the receiving jig 10, the cutting auxiliary body 43, and the sealer main body lower part 52 to the initial positions. Article 8 mounted on a jig 10 receives returns the opening 83 to the one side toward the horizontal plate 12 with a button switch G ₁ press a desired product that are sealed with a film strip 35. The delivery of the predetermined length of the filmstrip 3 from the reel R ₁ to the motor is operated, and winder R ₂ is wound a predetermined length min the filmstrip 3, opening a new symbol mark 31 21 It is arranged directly above.
After the product is removed from the receiving jig 10, a new article 8 is mounted on the receiving jig 10, and if the push button switch is pressed, the same operation as described above is repeated, and the products are sequentially manufactured.
In FIG. 8, reference numeral 621 denotes a guide column that stands on the base table 62, and reference numeral 40b denotes a guide hole provided in the horizontal plate. The guide column 621 is inserted to smooth the vertical movement of the horizontal plate 40. Is. Reference numerals b ₁ and n ₁ denote bolts and nuts for screwing and fixing the pillars 94 to the substrate 61 and the upper plate 93, and reference numeral b ₂ denotes bolts for fixing the base base 62 to the substrate 61.

本実施形態は刃部２２をダイカッタ２に設け、切断補助体４３の下面４３ａを平坦にして、刃部２２と切断補助体４３の下面４３ａとで帯状フィルム３を挟着カットし、フィルム片３５を切り離したが、次の構成を採ることもできる。すなわちダイカッタ２の開孔２１の周縁に刃部を設けず、代わって切断補助体４３の下面４３ａで通過孔４３ｂの周縁下面側にフィルム片３５を切取るための刃部を設けるのである。斯る場合は、開孔２１及び刃部の形状はフィルム片３５の形になるが、ダイカッタ２の上半部２１ａの開孔２１の大きさが切断補助体４３に設けた刃部の大きさより僅かに小さくなる。そのため、シーラ下部５２を開孔２１内に進入させてフィルム片３５で開口部８３を塞ぐ際に若干抵抗があるので本実施形態の方が好ましいが、特に支障になるものでない。 In the present embodiment, the blade portion 22 is provided on the die cutter 2, the lower surface 43 a of the cutting auxiliary body 43 is flattened, the band-shaped film 3 is sandwiched and cut between the blade portion 22 and the lower surface 43 a of the cutting auxiliary body 43, and the film piece 35 However, the following configuration can also be adopted. That is, a blade portion is not provided on the periphery of the opening 21 of the die cutter 2, and a blade portion for cutting the film piece 35 on the lower surface side of the periphery of the passage hole 43 b is provided instead of the lower surface 43 a of the cutting aid 43. In such a case, the shape of the opening 21 and the blade portion is a film piece 35, but the size of the opening 21 in the upper half 21 a of the die cutter 2 is larger than the size of the blade portion provided in the cutting auxiliary body 43. Slightly smaller. Therefore, this embodiment is preferred because there is a slight resistance when the sealer lower part 52 enters the opening 21 and the opening 83 is blocked by the film piece 35, but this is not particularly troublesome.

このように構成したシール機及びこれを用いた物品の開口部のシール方法によれば、従来技術１〜３等と異なり、物品８の上面８２の大きさよりも小さなフィルム片３５であっても、その物品８の上面８２に該フィルム片３５を熱シールできる。物品８(容器)の外径よりも小さな径のフィルム片３５であってもトップシール可能で、物品８の上面中央に設けられた開口部８３を塞いで熱シールできる。
しかも、ダイカッタ２と切断補助装置４を用いた帯状フィルム３からのフィルム片３５の抜取り工程と、シーラ５を用いたシール工程を同じ箇所で行うことができる。図１２,図１３のごとく従来技術１,２ではシール工程と抜取り工程は別の場所になりそのための大きな設備スペースを要したが、本シール機によれば同一箇所で賄えるので設備のコンパクト化が図れる。
さらに、従来技術１等においては搬送用バケット治具ｂｇの大きさや、シール工程,抜取り工程の設備の規制を受けてバケット容器(物品)Ｐのバケットピッチが大きくなる傾向にあり、従来は帯状フィルムの図柄マーク３１のピッチが大きくなっていた。しかるに、本シール機においてはシール工程と抜取り工程が同一箇所で行われることから、図柄マーク３１のピッチＬ_１を小さくできる。従来技術１,２のようにバケット治具や設備の規制がないので、フィルム片３５用図柄マーク３１を最小限に詰めてピッチ配列できる。帯状フィルム３の有効利用率を最大限高めることができ、帯状フィルム３のムダを省き低コスト化,省資源化に貢献する。
加えて、帯状フィルム３のライン方向(進行方向)と、物品８のライン方向がそれぞれ独立しているので、シール機の両ライン構成が自在で、直線流れや回転テーブル流れ等の組込み可能で設計自由度を高める。 According to the sealing machine configured as described above and the method of sealing the opening of an article using the same, unlike the conventional techniques 1 to 3 and the like, even if the film piece 35 is smaller than the size of the upper surface 82 of the article 8, The film piece 35 can be heat sealed to the upper surface 82 of the article 8. Even the film piece 35 having a diameter smaller than the outer diameter of the article 8 (container) can be top-sealed, and the opening 83 provided in the center of the upper surface of the article 8 can be closed and heat-sealed.
Moreover, the step of extracting the film piece 35 from the belt-like film 3 using the die cutter 2 and the cutting auxiliary device 4 and the sealing step using the sealer 5 can be performed at the same location. As shown in FIGS. 12 and 13, in the prior arts 1 and 2, the sealing process and the extraction process are separate locations and require a large facility space. However, according to this sealing machine, the facility can be made compact because it can be provided at the same location. I can plan.
Further, in the prior art 1 and the like, the bucket pitch of the bucket container (article) P tends to increase due to the size of the conveying bucket jig bg and the restrictions of the equipment for the sealing process and the extraction process. The pitch of the symbol mark 31 of the above was large. However, since the process sampling and sealing step is carried out at the same places in this sealing machine, it is possible to reduce the pitch L ₁ of the symbol mark 31. Unlike the prior arts 1 and 2, there is no regulation of the bucket jig or equipment, so that the pattern marks 31 for the film pieces 35 can be arranged in a pitch arrangement with a minimum. The effective utilization rate of the belt-like film 3 can be maximized, and the waste of the belt-like film 3 is eliminated, contributing to cost reduction and resource saving.
In addition, since the line direction (traveling direction) of the belt-like film 3 and the line direction of the article 8 are independent from each other, both line configurations of the sealing machine can be freely configured, and linear flow and rotary table flow can be incorporated. Increase the degree of freedom.
