Description

この発明は、樹脂製チューブ容器の開口部をシールするためのシール装置に関し、特にチューブ容器の加熱位置とクランプシール位置との距離を短縮して、チューブ容器の移動時間を短くすることにより、移動に伴う加熱されたチューブ容器の開口部の温度低下を減少せんとするものである。   The present invention relates to a sealing device for sealing an opening of a resin tube container, and in particular, by moving the tube container by shortening the distance between the heating position of the tube container and the clamp seal position and shortening the moving time of the tube container. It is intended to reduce the temperature drop at the opening of the heated tube container.

従来、流動性を有する化粧料等の中味を収納する樹脂製チューブ容器は、その口部をキャップで閉止した後、開口部から中味を充填し、充填後開口部をヒートシールしてチューブ容器としている。かかるチューブ容器のヒートシールにあっては、チューブ容器の開口部を加熱後、シール位置まで移動してシールするため、移動している間に開口部の温度が下がり、接着不良、即ちチューブ容器の開口部が時間の経過や微少な圧力によって開口してしまう、いわゆるパンクという現象が発生していた。そこで、従来、別個のステーションとして離れて配置されていた加熱ステーションとクランプステーションを一体にして、同一ステーション内に納めることにより、加熱からシールまでの時間の短縮を図って、開口部のパンクを回避した装置が、特許文献１に開示されている。しかしながら、この特許文献１の装置にあっても、チューブ容器は、加熱ステーションからクランプステーションに下降する距離があるため、相当高い温度での加熱が求められており、パンクを完全に解消するには充分ではなかった。そのため、偏平ノズルを使用した加熱装置により、チューブ容器のヒートシールの最終完成型に近い形態で加熱、圧着を行い、温度低下への対策を図っている。   Conventionally, resin tube containers for storing the contents of cosmetics with fluidity, etc., after closing the mouth with a cap, filling the contents from the opening, heat sealing the opening after filling, as a tube container Yes. In such heat sealing of the tube container, since the opening of the tube container is heated and then moved to the sealing position to be sealed, the temperature of the opening decreases during the movement, resulting in poor adhesion, that is, the tube container. A so-called puncture phenomenon has occurred in which the opening portion opens due to the passage of time or a slight pressure. Therefore, the heating station and the clamping station, which were conventionally arranged separately as separate stations, are integrated into the same station, thereby shortening the time from heating to sealing and avoiding puncture of the opening. Such a device is disclosed in Patent Document 1. However, even in the apparatus of Patent Document 1, since the tube container has a distance that descends from the heating station to the clamp station, heating at a considerably high temperature is required, and to completely eliminate puncture. It was not enough. Therefore, a heating device using a flat nozzle is used for heating and pressure bonding in a form close to the final completed type of heat sealing of the tube container, thereby taking measures against temperature drop.

しかしながら、かかる偏平ノズルを使用した加熱装置は、特許文献２に開示されるようなチューブを回転しつつ加熱する加熱装置に比して、特殊な加熱ノズルの使用が必要となり、それに伴って周辺の機構やシステムの変更が必要となると共に、クランプ機構も予め予備的なクランプ状態を保障する機構や構造が必要とされる問題があった。特に、偏平ノズルの噴出孔から噴出した熱風が、チューブ容器の開口部の内周面を加熱するため、噴出孔近傍が高温となり加熱斑が発生し、シール強度の低下をもたらすと共に、外観を悪くし、品質にバラツキが発生するおそれがあった。   However, a heating device using such a flat nozzle requires the use of a special heating nozzle as compared with a heating device that heats a tube as disclosed in Patent Document 2, and in accordance therewith, The mechanism and the system need to be changed, and the clamp mechanism also has a problem that a mechanism and a structure for ensuring a preliminary clamp state in advance are required. In particular, the hot air blown from the flat nozzle discharge hole heats the inner peripheral surface of the opening of the tube container, so that the vicinity of the discharge hole becomes hot, causing heating spots, resulting in a decrease in seal strength and a poor appearance. However, the quality may vary.

この発明は、加熱ステーションとクランプステーションを同一ステーション内に配置したシール装置であって、チューブ容器のクランプ部加熱位置からシール位置までの移動距離を従来のものよりも更に短くすることによって、温度低下に伴う種々の問題を解決すると共に、チューブを回転しつつ加熱する方式の使用を可能とし、これによって偏平加熱ノズルや予備的なクランプ機構を不要とする。   The present invention is a sealing device in which a heating station and a clamping station are arranged in the same station, and the temperature of the tube container is lowered by making the moving distance from the heating position of the clamp portion of the tube container to the sealing position even shorter than the conventional one. In addition to solving various problems associated with the above, it is possible to use a method of heating while rotating the tube, thereby eliminating the need for a flat heating nozzle and a preliminary clamping mechanism.

この発明は、中味を充填した樹脂製チューブ容器のキャップで閉止される口部と反対側の開口部をシールするシール装置であって、固定されたヒートステーションと、該ヒートステーションの下方の所定の高さに配置されたクランプステーションと、樹脂製チューブ容器の口部に取り付けたキャップ又は樹脂製チューブ容器の肩部を把持する搬送用治具と、搬送用治具を垂直方向に上下動するとともに水平回転させる回転昇降部材と、搬送用治具を水平方向に移動する搬送装置と、を備え、クランプステーションには、ロータリーアクチュエータの円板状の回転板と板状のクランクを連結した水平方向に作動するクランクでグリッパーを所定高さのまま水平方向に開閉作動してチューブ容器の開口部を圧着冷却してクランプシールするクランク駆動機構を備えることにより、ヒートステーションで樹脂製チューブを回転させながら開口部を加熱した直後にクランプステーションで開口部をシールすることを特徴とする。
The present invention relates to a sealing device for sealing an opening on the opposite side to a mouth closed by a cap of a resin tube container filled with a content, and a fixed heat station , and a predetermined lower part of the heat station. A clamp station placed at a height, a cap attached to the mouth of the resin tube container or a shoulder for holding the shoulder of the resin tube container, and a vertical movement of the transport jig A rotary elevating member that rotates horizontally, and a conveying device that moves the conveying jig in the horizontal direction . The clamp station is connected in a horizontal direction to which a disk-shaped rotating plate and a plate-shaped crank of the rotary actuator are connected. A clamp that clamps and seals the opening of the tube container by crimping the opening and closing of the tube container in a horizontal direction with the gripper operating at a predetermined height. By a drive mechanism, characterized by sealing the opening in the clamping station immediately after heating the opening portion while rotating the resin tube in heat station.

本発明の樹脂製チューブ容器のシール装置によれば、チューブ容器の開口部を加熱後、シール位置まで移動してシールする必要がないため、又、クランプ機構部の寸法、特に高さ方向の寸法を低くできるため、加熱位置からシール位置までの移動に伴う温度低下を少なくし、温度低下による開口部の接着不良、いわゆるパンクを解消することができる。又、特許文献１に見られる偏平加熱ノズルや予備的なクランプを不要とするため、装置の簡略化やコストの低減を図ることができる。更に、チューブを回転しつつ加熱する方式を採用することができるので、局部的な加熱によりもたらされる加熱斑の発生を防止し、品質の低下を回避することも可能となる。   According to the sealing device for a resin tube container of the present invention, it is not necessary to move the tube container opening to the sealing position after heating, so that the dimensions of the clamp mechanism, particularly the height direction, are not required. Therefore, it is possible to reduce the temperature drop caused by the movement from the heating position to the seal position, and to solve the adhesion failure of the opening due to the temperature drop, so-called puncture. Moreover, since the flat heating nozzle and preliminary clamp which are seen by patent document 1 are unnecessary, an apparatus can be simplified and cost reduction can be aimed at. Furthermore, since a method of heating while rotating the tube can be adopted, it is possible to prevent the occurrence of heating spots caused by local heating and to avoid deterioration in quality.

この発明の好ましい実施の形態を、以下に詳細に説明する。図１〜５は、ヒートステーション(２)とクランプステーション(３)が上下に配置された単一のステーションにおける作動工程を示し、図１は充填ステーションから中味を充填されたチューブ容器がクランプステーションに到着した状態、図２はチューブ容器が図１の到着位置からヒートステーションに上昇した状態、図３は加熱後チューブ容器がヒートステーションからクランプステーションに下降した状態、図４はクランプステーションでチューブ容器の開口部をクランプシールしている状態、図５は開口部のヒートシールが終了し、クランプステーションのクランプ機構がチューブ容器から後退した状態を、それぞれ示している。   Preferred embodiments of the present invention will be described in detail below. 1 to 5 show the operation process in a single station where the heat station (2) and the clamping station (3) are arranged one above the other, and FIG. 1 shows that the tube container filled with the contents from the filling station to the clamping station. 2 shows a state in which the tube container has been raised from the arrival position in FIG. 1 to the heat station, FIG. 3 shows a state in which the tube container has been lowered from the heat station to the clamp station, and FIG. FIG. 5 shows a state where the opening is clamp-sealed, and FIG. 5 shows a state where the heat sealing of the opening is completed and the clamping mechanism of the clamping station is retracted from the tube container.

各図において(１)は、樹脂製チューブ容器であり、容器の口部はキャップで閉止され、口部と反対側の開口部(図において上部)は開口され、充填ステーション(図示せず)において流動性を有する化粧料等の中味が充填されている。チューブ容器の素材は、加熱により溶融し圧着により接着する樹脂材料であれば特の限定されないが、収納される中味の性質、性状により求められる樹脂材料が特定される。   In each figure, (1) is a resin tube container, the container mouth is closed with a cap, the opening opposite to the mouth (upper part in the figure) is opened, and at a filling station (not shown) The contents of cosmetics having fluidity are filled. The material of the tube container is not particularly limited as long as it is a resin material that melts by heating and adheres by pressure bonding, but the resin material required by the nature and properties of the contents to be stored is specified.

チューブ容器(１)は、搬送装置(５)に着脱自在に装着された搬送用治具(４)に挿着保持されており、回転・昇降部材(６)に載置されて搬送用治具(４)と共に上昇下降する。図２は、チューブ容器(１)がヒートステーション(２)に上昇し、開口部が熱風吹出ノズル(８)に挿着され、加熱溶融される状態を示しており、上昇位置においてチューブ容器(１)は、回転しつつ加熱され、局部的な加熱による加熱斑の発生が抑制されている。熱風送風管(９)から送給される熱風が、吹出ノズルから吹き出され、チューブ容器の開口部を加熱した後、排気筒(７)から排気される。尚、ヒートステーション(２)は、かかる回転式の加熱方式に限定されるものではないことは勿論である。   The tube container (1) is inserted and held in a transport jig (4) that is detachably mounted on the transport device (5), and is placed on the rotating / lifting member (6) to be transported. It goes up and down with (4). FIG. 2 shows a state in which the tube container (1) is raised to the heat station (2), the opening is inserted into the hot air blowing nozzle (8), and is heated and melted. ) Is heated while rotating, and the generation of heating spots due to local heating is suppressed. Hot air fed from the hot air blower tube (9) is blown out from the blowout nozzle, heats the opening of the tube container, and is then exhausted from the exhaust tube (7). Needless to say, the heat station (2) is not limited to such a rotary heating method.

ヒートステーション(２)において開口部の内側が加熱され、次段のクランプ圧着のために溶融状態となったチューブ容器(１)の開口部は、クランプステーション(３)に下降する。クランプステーション(３)は、後述するように、ロータリーアクチュエーターで駆動されるクランク機構で構成されているため、その高さを低く構成することができ、ヒートステーションからクランプステーションまでの下降距離を極めて短く設定し、移動に伴う時間を短くすることができるため、温度低下を最小限に留めることが可能となる。   The inside of the opening is heated in the heat station (2), and the opening of the tube container (1), which is in a molten state due to the subsequent clamp bonding, descends to the clamp station (3). As will be described later, the clamp station (3) is composed of a crank mechanism that is driven by a rotary actuator, so that the height of the clamp station can be reduced, and the descending distance from the heat station to the clamp station is extremely short. Since the time required for the setting and the movement can be shortened, the temperature drop can be minimized.

クランプステーション(３)は、加熱溶融されたチューブ容器(１)の開口部を挟圧し、クランプシールする一対のグリッパー(10)と、該グリッパー(10)を相互に接近若しくは離間するクランク(11)及びロータリーアクチュエータ(12)からなるクランク駆動機構を備える。グリッパー(10)の下部には、チューブ容器(１)の開口部をクランプシールし易いように挟持する挟持具(13)が一体に取り付けられている。   The clamp station (3) includes a pair of grippers (10) that clamp and seal the opening of the heated and melted tube container (1), and a crank (11) that approaches or separates the grippers (10) from each other. And a crank drive mechanism comprising a rotary actuator (12). A gripping tool (13) that clamps the opening of the tube container (1) so as to be clamp-sealed is integrally attached to the lower portion of the gripper (10).

クランプステーション(３)では、図４に示すように、加熱溶融されたチューブ容器(１)の開口部を挟持具(13)で挟みながら、グリッパー(10)でクランプシールする。開口部がクランプシールされた後、クランク駆動機構の作動により、グリッパー(10)は、図５に示すようにチューブ容器(１)から離れるように水平方向に移動し、次段のステーションへのチューブ容器の移送に備える。   As shown in FIG. 4, the clamp station (3) clamps and seals with the gripper (10) while sandwiching the opening of the heated and melted tube container (1) with the clamping tool (13). After the opening is clamp-sealed, the gripper (10) is moved horizontally away from the tube container (1) as shown in FIG. Prepare for container transfer.

図６は、クランプステーションの左右一対のグリッパー(10)と該グリッパーを駆動するクランク駆動機構を平面から見た模式図であり、図において右側のグリッパーは、案内レール(14)に案内されて水平方向に摺動自在であり、左側のグリッパーは、案内レール(14)により水平方向に案内されるフレーム(15)に連結されて水平方向に摺動自在である。ロータリーアクチュエータ(12)に一方を連結された一対のクランク(11)の他方が、右側のグリッパー若しくは連結フレーム(15)に連結される。ロータリーアクチュエーター(12)が右方向に回転するとき、グリッパーは互いに離間する方向に移動する(図６Ａ)。又、逆に左方向に回転するとき、グリッパーは互いに接近し、チューブ容器の開口部を挟圧して、クランプシールする。   FIG. 6 is a schematic view of a pair of left and right grippers (10) of the clamp station and a crank driving mechanism for driving the grippers as viewed from above, and the right gripper in the drawing is guided by a guide rail (14) and is horizontally The left gripper is slidable in the horizontal direction by being connected to the frame (15) guided in the horizontal direction by the guide rail (14). The other of the pair of cranks (11), one of which is connected to the rotary actuator (12), is connected to the right gripper or the connection frame (15). When the rotary actuator (12) rotates to the right, the grippers move away from each other (FIG. 6A). On the other hand, when rotating in the left direction, the grippers approach each other, clamp the opening of the tube container, and clamp and seal.

グリッパー(10)は、チューブ容器(１)の開口部を圧着してそこを封止し得る一対の部材であり、チューブ容器の開口部に向かって接近し、或いは離間する。かかるグリッパー(10)は、従来のクランプステーションに用いられているものと実質的に同じ構造のものであるが、この発明にあっては案内レール(14)にそって水平に移動するように構成されている。ロータリーアクチュエータ(12)は、正逆に回転する回転板を備え、該回転板上に円弧板状の一対のクランク(11)の一端が揺動自在に連結される。一方のクランク(11)の他端は、前記グリッパー(10)の一方に連結され、他方のクランク(11)の他端は、連結フレーム(15)を介して他方のグリッパーに連結されている。   The gripper (10) is a pair of members that can crimp and seal the opening of the tube container (1), and approaches or separates toward the opening of the tube container. The gripper (10) has substantially the same structure as that used in the conventional clamping station, but in the present invention, the gripper (10) is configured to move horizontally along the guide rail (14). Has been. The rotary actuator (12) includes a rotating plate that rotates in the forward and reverse directions, and one end of a pair of arc-shaped cranks (11) is swingably connected to the rotating plate. The other end of one crank (11) is connected to one of the grippers (10), and the other end of the other crank (11) is connected to the other gripper via a connecting frame (15).

ロータリーアクチュエータ(12)が、図６Ａに示すように右回転するとき、一対のグリッパー(10)は、離間するように移動する。逆に、図６Ｂに示すようにロータリーアクチュエータ(12)が、左回転するとき一対のグリッパー(10)は接近し、グリッパーの間でチューブ開口部を挟圧してクランプシールする。クランク機構を構成するグリッパー、クランク及び該クランクが連結されるロータリーアクチュエータの回転板、案内レール、連結フレームは、いずれも高さのない薄い板状の部材からなるものであるから、全体の高さを低く構成することができる。   When the rotary actuator (12) rotates clockwise as shown in FIG. 6A, the pair of grippers (10) move away from each other. On the contrary, as shown in FIG. 6B, when the rotary actuator (12) rotates counterclockwise, the pair of grippers (10) approach each other, clamp the tube opening between the grippers and clamp the seal. Since the gripper constituting the crank mechanism, the rotary plate of the rotary actuator to which the crank is connected, the guide rail, and the connecting frame are all made of a thin plate-like member having no height, the overall height Can be configured low.

チューブ容器(１)の開口部をクランプシールするためのグリッパーを駆動するクランク駆動機構は、クランクとロータリーアクチュエータからなるものであるが、かかるクランク駆動機構は、実質的にクランク(11)の厚みと案内レール(14)若しくは連結フレーム(15)の厚みにより高さ方向の寸法が規定される。すなわち、これらの部材は水平方向に移動する機構であるとともに、作用力も水平方向に付加されるものであるから、厚み方向の強度は必要とされない。したがって全体の高さを小さな構造とすることが可能となる。   The crank drive mechanism for driving the gripper for clamping and sealing the opening of the tube container (1) is composed of a crank and a rotary actuator. The crank drive mechanism is substantially equal to the thickness of the crank (11). The height dimension is defined by the thickness of the guide rail (14) or the connecting frame (15). That is, since these members are mechanisms that move in the horizontal direction and acting force is also applied in the horizontal direction, strength in the thickness direction is not required. Therefore, it becomes possible to make the whole height small structure.

図７は、この発明にかかるクランク駆動機構と従来のアームクランプ駆動機構の高さを対比した説明図である。従来のアームクランプ機構は、図７Ａに示すように、縦方向に連結される複数のアームを駆動して、一対のグリッパーを接離する構造であるため、高さ方向の寸法が大きくなる共に、ヒートステーションを構成するヒーター部がアームクランプ機構の内部空間に配置されるため、全体の構成が大型化するのを避けることができなかった。   FIG. 7 is an explanatory diagram comparing the heights of the crank drive mechanism according to the present invention and the conventional arm clamp drive mechanism. As shown in FIG. 7A, the conventional arm clamp mechanism has a structure in which a plurality of arms connected in the vertical direction are driven to contact and separate a pair of grippers. Since the heater part which comprises a heat station is arrange | positioned in the internal space of an arm clamp mechanism, it was inevitable that the whole structure enlarged.

したがって、図７Ｂに示すように、この発明の機構の高さが約１８０mmであるのに対し、従来のアームクランプ駆動機構の高さは約９００mmであり、本発明のクランク駆動機構は、従来の駆動機構の約５分の１の高さである。又、従来のシリンダーでグリッパーを駆動する機構にあっても、装置全体が大型化し、高さ方向の寸法も大きくなる。この発明のクランク駆動機構によれば、高さ方向の寸法が小さいため、チューブ容器の上昇・下降距離が短くなり、移動時間を短縮できるため、ヒートステーションで加熱されたチューブ容器の温度低下を小さくすることができる。このため、チューブ容器のパンクの発生を大幅に低減できると共に、温度低下を見越した過剰な加熱をするおそれがなく、最適な加熱温度の選択による省エネルギー化を図ることができる。   Therefore, as shown in FIG. 7B, the height of the mechanism of the present invention is about 180 mm, whereas the height of the conventional arm clamp drive mechanism is about 900 mm. It is about 1/5 the height of the drive mechanism. Further, even in a mechanism for driving a gripper by a conventional cylinder, the entire apparatus becomes large and the height dimension increases. According to the crank drive mechanism of the present invention, since the dimension in the height direction is small, the ascending / descending distance of the tube container is shortened and the moving time can be shortened, so the temperature drop of the tube container heated in the heat station is reduced. can do. For this reason, generation | occurrence | production of the puncture of a tube container can be reduced significantly, there is no possibility of excessive heating in anticipation of a temperature drop, and energy saving can be achieved by selecting an optimum heating temperature.

また、加熱からヒートシールまでの時間を比較すると、図７Ａに示す従来のアームクランプ駆動機構では、０．７５秒の時間を要するのに対して、図７Ｂに示す本発明のクランク駆動機構では０．２０秒と著しく差があり、この時間の差がシール時の温度低下の差となって現れ、本発明においては、チューブ容器のパンク発生が著しく低下する。   When comparing the time from heating to heat sealing, the conventional arm clamp drive mechanism shown in FIG. 7A requires 0.75 seconds, whereas the crank drive mechanism of the present invention shown in FIG. .20 seconds is significantly different, and this time difference appears as a difference in temperature drop during sealing, and in the present invention, the occurrence of puncture of the tube container is significantly reduced.

更に、本発明とチューブ容器の開口部を加熱後、シール位置まで移動してシールするタイプの従来のシール装置とを比較する。本発明のシール装置でチューブ容器(１)の開口部を３６０℃の熱風で加熱すると加熱直後の開口部の温度は１２５℃、シール直前の平均温度は１２３℃で、シールするまでに２℃しか低下してないのに対して、シール部まで移動してシールする従来のシール装置では、チューブ容器(１)が下降するのに０．１秒、横方向に移動するのに０．５秒かかるので開口部を３６０℃の熱風で加熱しても、シール時の開口部の平均温度は９２℃と著しく低下してしまう。このように本発明のクランク駆動機構を用いるシール装置は、著しく温度低下が少ないことが判明した。   Further, the present invention is compared with a conventional sealing device of the type that seals the tube container after the opening of the tube container is heated and moved to the sealing position. When the opening of the tube container (1) is heated with hot air of 360 ° C. in the sealing device of the present invention, the temperature of the opening immediately after the heating is 125 ° C., the average temperature immediately before the sealing is 123 ° C. In contrast, the conventional sealing device that moves to the seal portion and seals it takes 0.1 seconds for the tube container (1) to descend and 0.5 seconds for the lateral movement. Therefore, even if the opening is heated with hot air of 360 ° C., the average temperature of the opening at the time of sealing is remarkably lowered to 92 ° C. As described above, it has been found that the seal device using the crank drive mechanism of the present invention has a very low temperature drop.
