本発明は、一対のシールジョーを用いてゲープルトップ
型容器の頂部をシールする方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field] The present invention relates to a method of sealing the top of a gape-top container using a pair of sealing jaws.
牛乳その他の液体食品を販売するための容器として、第
6図、第7図に示すように頂部が屋根形になったゲーブ
ルトップ型と称される容器がある。2. Description of the Related Art As containers for selling milk and other liquid foods, there is a container called a gable top type, which has a roof-shaped top as shown in FIGS. 6 and 7.
このような容器(八)に液体食品を封入するには、角筒
状とした容器の底を成型して有底とし、その容器(A′
)の開口されている頂部(第5図の上側)から液体食品
を充填し、しかる後各折目線(al、 (bl、 (C

をそれぞれ第6図に示すように折曲し、重ね合わされた
2枚の内側密封フィン(C”)、(c’)と外側密封フ
ィン(e″)、(e′)を一対のシールジョーで互いに
ヒートシールすることが行われている。In order to enclose liquid food in such a container (8), the bottom of the rectangular cylindrical container is molded to have a bottom, and the container (A'
) from the open top (upper side in Figure 5), and then fill the liquid food at each fold line (al, (bl, (C
1, (d), tel, (f) to two triangular panels (a'), folding panel (b''), inner sealing fin (Co
), outer sealing fin (e゛), sloped roof panel (f”)
As shown in Fig. 6, bend the two overlapping inner sealing fins (C''), (c') and outer sealing fins (e''), (e') with a pair of sealing jaws. They are heat sealed together.
ところが、従来のシールジター(1″)、(1°)は第

、印刷面の品質の低下につながる。However, the conventional seal jitter (1"), (1°) is designed to move in a straight line as shown in Figure 8. A pair of seal jaws (1"),
During this movement of (1'), it scrapes the outer surface of the sloped roof panel (fo), causing damage to the container and leading to a reduction in the quality of the printed surface.
一方、この種の容器の中には第5図ないし第8図に示す
ように、傾斜屋根パネル(f゛)部分にスパウト(B)
を取り付けたものもあり、一対のシールジョー(1’)
、(1”)が上記のような軌跡を描くとこのスパウト(
B)に当るという不都合もある。On the other hand, as shown in Figures 5 to 8, this type of container has a spout (B) on the sloped roof panel (f).
Some are fitted with a pair of sealing jaws (1').
, (1”) draws the trajectory shown above, this spout (
There is also the inconvenience of falling under B).

Conventionally, when heat-sealing the containers (2) and (e') to each other, guide rods (2) and (2), which gradually become narrower toward the front, are used as shown in FIG. Ao
) was passed between both guide rods (21 and +21), and the top opened between them was gradually narrowed down to AO + 'AI + Ax. In this case, both guide rods +21. (2) The pair of sealing jaws (1”) and (1°) cannot be operated while the top of the container is squeezed (the sealing jaws (1°) hit the guide rod (2))
Therefore, the guide rods (2+, (21) have to be stopped before the guide rods f21. The top narrowed down at the point where it exits from 2+ is the 9th
After passing through the state of A3 in the figure, the container is opened again as shown by A4, and there is a drawback that the liquid food filled in the instant container (Ao) spills out.
飛び敗った液体食品が内側密封フィン(c’)、(c’

ると、シール性が悪くなり、シール不良という重大事態
に発展する。The liquid food that has flown through the inner sealing fins (c'), (c'
), the outer sealing fins (e'), and the inside of the outer sealing fins (e') will deteriorate the sealing performance, leading to a serious situation of seal failure.
本発明は、このような欠点を解消することを目的とする
ものである。The present invention aims to eliminate such drawbacks.
本発明では、ゲーブルトップ型容器の頂部をシールする
に当り、一対のシールジョー(11,fl)を第1図に
示すように円弧軌跡を描くごとく互いに内側に稼働させ
る。In the present invention, when sealing the top of a gable-top type container, a pair of sealing jaws (11, fl) are moved inward from each other in an arcuate trajectory as shown in FIG.

ドの役をなし、容器(Ao)の頂部が徐々に絞られて行
くから、別にガイドを設ける必要がない。When the pair of sealing jaws (11, fl) are operated in this manner to seal the top of a gable-top container, the sloped roof panel (f) is moved from the fold line ffl to the outer sealing fin from the fold line (el). (eo) is gradually bent, but at this time, the inner lower edge of the seal jaw (1+) can be pushed right next to the crease line (e). At this time, the seal jaw (1) itself acts as a kind of guide, and the top of the container (Ao) is gradually squeezed, so there is no need to provide a separate guide.

。A pair of seal jaws (1), fl) are arranged above this conveyance path (4) so as to face each other in the left-right direction in FIG. As shown in Fig. 1, the seal jaws (11, +11 are assumed to operate in a circular arc trajectory.In order to operate the pair of seal jaws (11, (11) in this manner, in the embodiment, the This shows the case where the link mechanism shown in FIG. Main body (5) left and right 2
Book link (6), (2 bases on the left and right (7) by 61

(Two dogleg-shaped levers aυ that are connected to 71 and have their lower ends pivoted to vertically movable lifting rod αω, the upper end of lever αυ is connected to the main body (5), and another
The upper ends of the book levers Oz are respectively pivotally connected to the main body (8). When the lifting rod αω is raised from the state shown in FIG. 2 to the position shown in FIG. +71 to the right in Fig. 2, the main body (8) is attached to the two left and right bases (
71, (relative to 71 to the left in FIG. 2).Therefore, the container (8°) on the conveying path (4) has its sloped roof panel (f") away from the fold line (f). The outer sealing fin (eo) is gradually bent from the fold line +81, and as shown in FIG. 3, the pair of sealing jaws (11
, (1) come into contact, two inner sealing fins (
A total of four pieces of c'L (C') and outer sealing fins (e'') and (e'') are overlapped and heat-sealed to each other.

いということである。After heat sealing, the pair of sealing jaws (11, (1) return to the original state (Fig. 2). Therefore, while the pair of sealing jaws +1), +1) is in operation, the link (6
1, (Ql causes an arcuate movement as shown in FIG. When the container (eo) is gradually bent, the inner lower edge of the seal jaws (11, +11 can be pushed right next to the crease line (el). Looking at this from another side, the container ( This means that the seal jaw (1) does not scrape the outer surface of the sloped roof panel (f'') of Ao), and as shown in the example, the spout (B) does not rub against the sloped roof panel (fo). Even if it is attached, the seal jaw (1) will not get in the way.

The lower end of the lifting rod 0ω is connected to the upper end of the piston rod αJ of the cylinder 041, and the lower end of the cylinder 00 is connected to a bell crank 060 that swings about the axis 0ω. And bell crank 0
The rotor 0η attached to the other end of ω is engaged with the groove of the plate cam 08, which rotates at a constant speed around the shaft 08). In this mechanism, when the plate cam 09 rotates at a constant speed in the direction of the arrow in FIG. 4 around the axis 0ω, the plate cam 0
The engagement position between Φ and trochanter 0"D changes, and the bell crank 00 swings around shaft 4 as a fulcrum. Therefore, the cylinder (14

おくものとする。In addition, a pair of sealing jaws (11, (11) connects the container (
While heat sealing the top of Ao), a pair of chenos (31, (31) shall be stopped in order to stop the container (8°).
