【解決手段】 一対のクランプ１０の回転領域から後退して待機する一対のクリップ爪２１を、包袋１１を支持する前記クランプ１０が停止すると同時に同クランプ上域に突き出すと共に、第１エアシリンダー２１で一対の可動爪２３を操作して前記一対のクリップ爪２１により前記包袋１１の両側縁を挟持する。そのあと間隔調整機３０の空気圧により前記一対のクリップ爪２１の間隔を広げて前記袋口を両側方向に緊張させて、両クリップ爪２１間で、包袋１１の袋口をシールバーにより溶着する。
【選択図】図１An opening edge of a wrapping bag that accommodates an article to be packed up to the vicinity of a bag mouth is relatively pinched and sealed by a pair of seal bars without leaving any wrinkles.
SOLUTION: A pair of clip claws 21 that are retracted from a rotation area of a pair of clamps 10 and stand by protrude to the upper area of the clamps at the same time when the clamps 10 that support the wrapping bag 11 are stopped. Then, the pair of movable claws 23 are operated so that both side edges of the wrapping bag 11 are clamped by the pair of clip claws 21. Thereafter, the gap between the pair of clip claws 21 is widened by the air pressure of the gap adjusting machine 30 to tension the bag mouth in both directions, and the bag mouth of the wrapping bag 11 is welded between the clip claws 21 with a seal bar. .

Description
本考案は、ロータリ袋詰包装機の袋口シールセクションにおいて、前記包袋の袋口に皺を残さずに加熱シールする装置に関する。 The present invention relates to a device for heat sealing in a bag mouth sealing section of a rotary bag filling and packaging machine without leaving any wrinkles in the bag mouth of the packaging bag.
下記の特許文献１には、１対１組のクランプでもって両側縁を挟持て吊り下げた包袋を、前記クランプと一体に円軌道に沿って断続移送し、その移送軌道において前記包袋に被包装物を充填したあと、シールセクションにおいて前記包袋の開口縁を一対のシールバーによって加圧しかつ溶着するロータリ包装機を開示するが、該文献でも明らかなように、前記シールセクションに配置するシールバーに対して前記のクランプが接触しないように、同クランプを下域に下げて包袋を挟持し運搬する構成である。 In Patent Document 1 below, a wrapping bag suspended with both side edges sandwiched by a one-to-one pair of clamps is intermittently transferred along a circular track integrally with the clamp, and the wrapping bag is transferred to the wrapping bag on the transfer track. A rotary wrapping machine is disclosed in which the opening edge of the wrapping bag is pressurized and welded by a pair of seal bars in the seal section after filling with an object to be packaged. In order to prevent the clamp from coming into contact with the seal bar, the clamp is lowered to the lower region to hold and carry the wrapping bag.
すなわち図４に示すように前記一対のクランプ１０は、包袋１１の開口縁に一定のシール代１２を残し、このシール代の下域を挟持するものである。この場合、包袋内部の被包装物の上面１３が、前記クランプ１０の上面近くにあると、前記一対のクランプ１０を相対離反しても袋口は緊張せず、前記袋口１４をシールバーで挟圧したとき、袋口１４は皺のあるシールが行われる可能性がある。特に図示するような３方シールの包袋１１は剛性が高くシールの発生度がそれだけ高くなる欠点があった。 That is, as shown in FIG. 4, the pair of clamps 10 leaves a certain seal margin 12 at the opening edge of the wrapping bag 11 and clamps a lower region of the seal margin. In this case, if the upper surface 13 of the packaged object inside the packaging bag is near the upper surface of the clamp 10, the bag mouth does not become tensioned even if the pair of clamps 10 are separated from each other, and the bag mouth 14 is sealed with the seal bar. There is a possibility that the bag mouth 14 is sealed with wrinkles. In particular, the three-side sealed wrapping bag 11 as shown in the figure has a drawback that the rigidity is high and the degree of occurrence of the seal is increased accordingly.
本考案は前記問題を解決するために、ロータリ袋詰め包装機におけるシールバーの設置セクションに、通常、クランプの通過領域から後退して待機する一対のクリップ爪を配置し、クランプの停止と同時に前記両クリップ爪を前記クランプの上域に突き出しかつ包袋の両側縁を挟持して袋口を両側方向に緊張させる機構と、前記シールバーの長さを、前記の緊張方向に離反した一対のクリップ爪間の値に設定し、前記クリップ爪間で前記シールバーにより前記袋口を溶着するようにした機構とを備えるごとく構成する。 In order to solve the above-mentioned problem, the present invention arranges a pair of clip claws that are usually retracted and wait from the passage area of the clamp in the installation section of the seal bar in the rotary bagging and packaging machine, and at the same time the clamp is stopped. A mechanism for projecting both clip claws to the upper region of the clamp and sandwiching both side edges of the bag to tension the bag mouth in both directions, and a pair of clips in which the length of the seal bar is separated in the tension direction And a mechanism that is set to a value between the claws and welds the bag mouth with the seal bar between the clip claws.
この装置に用いる包袋は、その底縁と両側縁とにそれぞれ２０ｍｍ前後のシール幅をもつ３方シール型であり、一方一対のクリップ爪は、前記包袋の両側シール部分のほぼ半分、約１０ｍｍづつを挟持して袋口を両側に緊張させ、このクリップ爪間でシールバーは、包袋の両側シール約１０ｍｍづつを含めて袋口を密封溶着する構成であるものと定義するものであり、前記の各数値の僅かな変更も前記定義の範囲に含むものである。 The wrapping bag used in this device is a three-sided seal type having a sealing width of about 20 mm at the bottom edge and both side edges, respectively, while the pair of clip claws are approximately half of the sealing parts on both sides of the wrapping bag. The bag mouth is tensioned to both sides by pinching 10 mm each, and the seal bar is defined as a structure in which the bag mouth is hermetically welded, including about 10 mm on both sides of the wrapping bag. The slight change of each numerical value is also included in the scope of the definition.
図１は図２の平面図であり、これら図面において一対１組のクランプ１０は包袋１１を挟持し、該包袋を円軌道に沿って運搬する過程で被包装物を充填し、シールセクションに到達して一時停止した状態を示している。この一対のクランプ１０に対向する一対のクリップ爪２０は、それぞれ腕２１の先端の固定爪２２に可動爪２３を、ピン２４を介して回転自在に支持し、第１エアシリンダー２５で前記可動爪２３を開閉操作する構成である。 FIG. 1 is a plan view of FIG. 2. In these drawings, a pair of clamps 10 sandwich a wrapping bag 11, fill the packaged material in the process of transporting the wrapping bag along a circular track, and seal sections. It shows the state where it reached and paused. The pair of clip claws 20 opposed to the pair of clamps 10 respectively support a movable claw 23 on a fixed claw 22 at the tip of an arm 21 via a pin 24 so that the movable claw can be rotated by a first air cylinder 25. 23 is configured to open and close.
前記の両クリップ爪２０を連結するエアシリンダー式の間隔調整機構３０は、
シリンダー本体３１の両側に突き出るピストンロツド３２それぞれに、前記の両クリップ爪２１を固定し、前記シリンダー本体３１に作用する流体圧によって、前記両クリップ爪２１を離反し、また接近させる構成であって、この場合シリンダー本体３１内をスライドするガイド棒３３が前記両クリップ爪２１の安定を図る構成である。
An air cylinder type interval adjusting mechanism 30 for connecting both the clip claws 20 is as follows.
The two clip claws 21 are fixed to the piston rods 32 projecting on both sides of the cylinder body 31, and the two clip claws 21 are separated and approached by the fluid pressure acting on the cylinder body 31, In this case, the guide rod 33 that slides in the cylinder body 31 is configured to stabilize the clip claws 21.
機台４０に固定する第２エアシリンダー４１のピストンロツド４２に、前記のシリンダー本体３１を連結しており、結果として前記の第２シリンダー４１は前記間隔調整機構３０を介して一対のクリップ爪２１を支持する形になり、前記第２シリンダー４１が両クリップ爪２１を前記包袋１１の存在域に進めると、一対の第１シリンダー２５により操作される可動爪２３は、図３の包袋１０両側縁シール幅の約半領域を挟持し、前記間隔調整機構３０が両クリップ爪２５の間隔を拡大することによって、袋口は利用側方向に緊張するのである。 The cylinder body 31 is connected to a piston rod 42 of a second air cylinder 41 that is fixed to the machine base 40, and as a result, the second cylinder 41 has a pair of clip claws 21 via the interval adjusting mechanism 30. When the second cylinder 41 advances both the clip claws 21 to the area where the wrapping bag 11 exists, the movable claws 23 operated by the pair of first cylinders 25 are arranged on both sides of the wrapping bag 10 shown in FIG. By sandwiching about a half region of the edge seal width and the interval adjusting mechanism 30 enlarges the interval between the two clip claws 25, the bag mouth is tensioned in the use side direction.
図２においてスリーブ５０に操作ロッド５１、５２を介して支持する一対のシールバー５５、５６は、前記両操作ロッド５１、５２に作用する動力により、図２において包袋１０の開口縁を挟圧シールするが、このシールバー５５、５６の長さは、両側のクリップ爪２１の間隔よりも僅かに短く設定がなされており、
クリップ爪間で同シールバー５５は、包袋両側の縦シー幅１５の約半分を含めて袋口を密封溶着する構成である。
2, the pair of seal bars 55 and 56 supported on the sleeve 50 via the operation rods 51 and 52 pinch the opening edge of the wrapping bag 10 in FIG. 2 by the power acting on the operation rods 51 and 52. The length of the seal bars 55 and 56 is set slightly shorter than the interval between the clip claws 21 on both sides.
The seal bar 55 between the clip claws is configured to seal and weld the bag mouth including about half of the vertical sea width 15 on both sides of the bag.
