Description

この発明は、一定間隔毎に形成されている分離用ミシン目で筒状包材を破断する筒状包材の破断ユニットに関する。   The present invention relates to a tubular packaging material breaking unit that breaks a tubular packaging material at a separation perforation formed at regular intervals.

例えば、一升瓶に充填された清酒等を、和紙や不織布等からなる筒状包材を用いて包装する包装装置としては、所定位置に搬送されてきた一升瓶に長尺の筒状包材を被せ、この筒状包材を所定長に切断した後、切断された筒状包材の下端部を折り畳んで接着すると共に、切断された筒状包材の上端部を掴んで回転させることによって絞った後、その絞られた筒状包材の上端部を下方側に折り返して、一升瓶の首部分にワイヤーテープ等を用いて結束するようにしたものがあり、こういった包装装置では、図７（ａ）、（ｂ）に示すように、マンドレル５１に嵌挿されることで所定形状に開口された筒状包材Ｐを送出しながら、筒状包材Ｐの切断端をクランパ５２によって把持して引き下げることにより、一升瓶Ｂに筒状包材Ｐを被せた後、筒状包材Ｐをサークルカッタ５３によって切断するようになっている。   For example, as a packaging device that wraps sake or the like filled in a bottle with a cylindrical packaging material made of Japanese paper or nonwoven fabric, the long bottle packaging material is put on the bottle that has been transported to a predetermined position. After this cylindrical packaging material is cut to a predetermined length, the lower end portion of the cut cylindrical packaging material is folded and bonded, and the upper end portion of the cut cylindrical packaging material is gripped and rotated to squeeze it. In some cases, the upper end of the squeezed cylindrical packaging material is folded downward and bound to the neck portion of the bottle with a wire tape or the like. In such a packaging device, FIG. ), As shown in (b), while feeding the cylindrical packaging material P that is inserted into the mandrel 51 and opened in a predetermined shape, the cutting end of the cylindrical packaging material P is gripped by the clamper 52 and pulled down. After covering the one bottle B with the cylindrical packaging material P, The packaging material P is adapted to cut the circle cutter 53.

特開平６−４０４２２号公報JP-A-6-40422

ところで、上述したような包装装置では、一升瓶Ｂに被せた筒状包材Ｐを、サークルカッタ５３を用いて所定長に切断しているが、サークルカッタを搭載すると、包装装置自体の構造が複雑になり、装置の製造コストも高くなるので、分離用ミシン目を一定間隔毎に予め筒状包材に形成しておき、または、筒状包材Ｐの送出途中で、一定間隔毎に分離用ミシン目を形成しながら、この筒状包材を一升瓶に被せた後、分離用ミシン目で筒状包材を破断することが考えられる。   By the way, in the packaging apparatus as described above, the cylindrical packaging material P placed on the one bottle B is cut into a predetermined length using the circle cutter 53. However, when the circle cutter is mounted, the structure of the packaging apparatus itself is complicated. Since the manufacturing cost of the apparatus becomes high, the separation perforation is formed in advance in the cylindrical packaging material at regular intervals, or for separation at regular intervals during the delivery of the cylindrical packaging material P. It is conceivable that the cylindrical packaging material is covered with a single bottle while forming the perforation, and then the cylindrical packaging material is broken at the separation perforation.

上述した包装装置では、筒状包材Ｐを送出しながら、筒状包材Ｐの切断端をクランパ５２によって把持して引き下げることにより、一升瓶Ｂに筒状包材Ｐを被せるようになっているので、分離用ミシン目が形成された筒状包材を使用する場合も、筒状包材を送出しながら、筒状包材の破断端を把持したクランパを引き下げることにより、一升瓶に筒状包材を被せた後、筒状包材の送出を停止した状態で、筒状包材の破断端を把持しているクランパをさらに引き下げることにより、分離用ミシン目で筒状包材を破断させることが考えられるが、このように、筒状包材の破断端を下方側に引っ張ることによって、筒状包材を分離用ミシン目で破断させるようにすると、破断するときの反動によって、破断された筒状包材に型くずれが発生し、筒状包材の上端部が下方側に位置ずれしてしまうので、一升瓶に被せられた筒状包材の上端部を掴みにくくなり、その後に行われる筒状包材の上端部の絞り工程に支障が生じるおそれがある。   In the packaging apparatus described above, the cylindrical packaging material P is covered on the one-bottle bottle B by feeding the cylindrical packaging material P while holding the pulling end of the cylindrical packaging material P by the clamper 52 and pulling it down. Therefore, even when using a cylindrical packaging material in which a perforation for separation is used, the cylindrical packaging material is pulled into the bottle by pulling down the clamper that holds the broken end of the cylindrical packaging material while feeding the cylindrical packaging material. After covering the material, the tubular packaging material is broken at the separation perforation by further lowering the clamper holding the broken end of the cylindrical packaging material in a state where the delivery of the cylindrical packaging material is stopped. However, as described above, when the tubular packaging material is broken at the perforation for separation by pulling the broken end of the tubular packaging material downward, the tubular packaging material is broken by the reaction when breaking. The cylindrical packaging material loses its shape and becomes cylindrical Since the upper end portion of the material is displaced downward, it becomes difficult to grasp the upper end portion of the cylindrical packaging material placed on the bottle, and the subsequent drawing process of the upper end portion of the cylindrical packaging material is hindered. There is a fear.

そこで、この発明の課題は、分離用ミシン目で破断された筒状包材が型くずれし難い筒状包材の破断ユニットを提供することにある。   Accordingly, an object of the present invention is to provide a rupture unit for a cylindrical packaging material in which the cylindrical packaging material that has been broken by a separation perforation is difficult to lose its shape.

The present invention provides a tubular packaging material breaking unit characterized by being broken.

また、上記の課題を解決するため、請求項２に係る発明は、一定間隔毎に分離用ミシン目が形成された長尺の筒状包材を、前記分離用ミシン目で順次破断する筒状包材の破断ユニットであって、前記筒状包材が嵌挿された状態で、所定位置に固定設置された内部固定体及び前記内部固定体の包材送出方向の下流側で包材送出方向に進退可能に支持された内部可動体と、前記内部固定体及び前記内部可動体に嵌挿された前記筒状包材の破断端を把持する把持手段と、前記筒状包材の破断端に最も近い前記分離用ミシン目の包材送出方向の上流側の近傍を前記内部固定体に押し付けて保持する上流側押え手段及び前記筒状包材の破断端に最も近い前記分離用ミシン目の包材送出方向の下流側の近傍を、前記内部可動体に押し付けて保持する下流側押え手段とを備え、前記上流側押え手段が前記筒状包材の破断端に最も近い前記分離用ミシン目の包材送出方向の上流側の近傍を前記内部固定体に押し付けて保持している状態で、前記筒状包材の破断端を把持している前記把持手段と、前記筒状包材の破断端に最も近い前記分離用ミシン目の包材送出方向の下流側の近傍を、前記内部可動体に押し付けて保持している前記下流側押え手段とを、同期をとりながら、包材送出方向の下流側に移動させることによって、前記筒状包材を、その破断端に最も近い前記分離用ミシン目で破断するようにしたことを特徴とする筒状包材の破断ユニットを提供するものである。 In order to solve the above-mentioned problem, the invention according to claim 2 is a cylindrical shape in which a long cylindrical packaging material in which a separation perforation is formed at regular intervals is sequentially broken at the separation perforation. A packaging material breaking unit, in which the tubular packaging material is fitted and inserted, and an internal fixed body fixedly installed at a predetermined position and a packaging material delivery direction downstream of the packaging material delivery direction of the internal stationary body An internal movable body supported so as to be able to advance and retreat, gripping means for gripping the fracture end of the cylindrical packaging material fitted into the internal fixed body and the internal movable body, and a fracture end of the cylindrical packaging material Upstream holding means for pressing and holding the upstream vicinity in the packaging material delivery direction closest to the separating perforation to the internal fixing member, and the separating perforation closest to the broken end of the cylindrical packaging material the vicinity of the downstream side of the timber feed direction, the downstream side to hold against the said internal movable member A e means holds against the vicinity of the upstream presser unit upstream of the nearest the separating perforation of packaging material feed direction to fracture end of the tubular packaging material in the inner fixed body In the state, the gripping means holding the broken end of the cylindrical packaging material, and the vicinity of the downstream side in the packaging material delivery direction of the separation perforation closest to the broken end of the cylindrical packaging material, By moving the downstream holding means pressed against and held by the internal movable body to the downstream side in the packaging material delivery direction while synchronizing, the tubular packaging material is closest to the broken end thereof. The present invention provides a rupture unit for a cylindrical packaging material characterized by rupturing at a separation perforation.

また、請求項１に係る発明の筒状包材の破断ユニットでは、上流側押え手段が筒状包材の破断端に最も近い分離用ミシン目の包材送出方向の上流側の近傍を内部固定体に押し付けて保持している状態で、筒状包材の破断端に最も近い分離用ミシン目の包材送出方向の下流側の近傍を、内部可動体に押し付けて保持している下流側押え手段を、包材送出方向の下流側に移動させることにより、筒状包材を分離用ミシン目で破断するようになっているので、筒状包材を破断するときの反動が少なく、破断された筒状包材が型くずれし難くなるという効果が得られる。 In the tubular packaging material breaking unit according to the first aspect of the present invention, the upstream holding means is internally fixed in the vicinity of the upstream side in the packaging material delivery direction of the separation perforation closest to the broken end of the tubular packaging material. The downstream presser that holds and holds the vicinity of the separation perforation closest to the broken end of the tubular packaging material in the packaging material delivery direction while being pressed against the body. By moving the means downstream in the packaging material delivery direction, the cylindrical packaging material is broken at the separation perforation, so there is little reaction when the cylindrical packaging material is broken, and it is broken.

The gripping means for gripping the broken end of the tubular packaging material and the broken end of the tubular packaging material most in the state where the vicinity of the upstream side of the packaging material delivery direction of the eye is pressed against and held by the internal fixed body The downstream holding means that holds the vicinity of the downstream side in the packaging material delivery direction of the near separation perforation against the internal movable body is moved to the downstream side in the packaging material delivery direction in synchronization. Therefore, there is little reaction when the cylindrical packaging material is broken, and an effect that the broken cylindrical packaging material is difficult to be out of shape can be obtained. In particular, since both ends of the broken tubular packaging material are held together, the tubular packaging material does not shrink.

以上のように、この包装装置１では、包材嵌挿部γにおいて、一升瓶Ｂに嵌挿された筒状包材Ｐを分離用ミシン目Ｍで破断する際、筒状包材Ｐの破断端を把持している包材クランパ２４と、筒状包材の破断端に最も近い分離用ミシン目Ｍの包材送出方向の下流側の近傍を、マンドレル２３の下側可動部２３ｂの外周面に押し付けて保持している一対の下側包材ホルダ２６とを、同期をとりながら、引き下げるようになっているので、筒状包材Ｐを破断するときの反動が少なく、破断された筒状包材Ｐが型くずれし難くなる。これによって、破断された筒状包材Ｐの上端部が位置ずれし難くなり、包材絞り部εにおいて、絞りチャックユニット４１が、一升瓶Ｂに嵌挿された筒状包材Ｐの上端部を確実に把持することができる。   As described above, in the packaging device 1, when the tubular packaging material P inserted and inserted into the one bottle B is broken at the separating perforation M in the packaging material insertion portion γ, the broken end of the tubular packaging material P The outer periphery of the lower movable portion 23b of the lower mandrel 23 has a packaging material clamper 24 and a separation perforation M closest to the broken end of the tubular packaging material in the vicinity of the downstream side in the packaging material delivery direction. The pair of lower wrapping material holders 26 that are pressed and held are pulled down while synchronizing, so that there is little reaction when the tubular wrapping material P is broken, and the broken tubular wrapping is broken. It becomes difficult for the material P to lose its shape. As a result, the upper end portion of the broken cylindrical packaging material P is difficult to be displaced, and in the packaging material throttle portion ε, the throttle chuck unit 41 moves the upper end portion of the cylindrical packaging material P that is inserted into the bottle B. It can be securely gripped.

なお、上述した実施形態では、一升瓶を筒状包材によって完全に包み込む包装装置に、本発明の筒状包材の破断ユニットを搭載した場合について説明したが、これに限定されるものではなく、例えば、合成樹脂フィルム等によって形成された筒状ラベルを、ＰＥＴボトル等の容器の胴部に嵌挿するラベル嵌挿装置に、本発明の筒状包材の破断ユニットを搭載することも可能であり、その場合は、筒状ラベルが分離用ミシン目を介して連続的に繋がった、筒状包材としての長尺のラベル形成基材をマンドレルによって円筒状に整形した後、本発明の破断ユニットによって、分離用ミシン目で破断し、これをＰＥＴボトル等の容器の胴部に嵌挿することになる。本発明の破断ユニットは、不織布や伸縮性を有する柔軟なフィルム等によって形成された筒状包材を分離用ミシン目で破断する場合にも、反動が起こりにくく、型くずれし難いため、高速で破断することができるので、この種の筒状包材に対して、特に有効である。   In the above-described embodiment, the case where the breaking unit of the tubular packaging material of the present invention is mounted on the packaging device that completely wraps the bottle with the tubular packaging material is not limited thereto. For example, it is also possible to mount the tubular packaging material breaking unit of the present invention on a label insertion device for inserting a cylindrical label formed of a synthetic resin film or the like into a body portion of a container such as a PET bottle. Yes, in that case, the cylindrical label is continuously connected through the perforation for separation, and after the long label forming substrate as a cylindrical packaging material is shaped into a cylindrical shape by a mandrel, the breakage of the present invention The unit breaks at the separation perforation and is inserted into the body of a container such as a PET bottle. The breaking unit of the present invention breaks at a high speed because the recoil is less likely to occur when the cylindrical packaging material formed by a nonwoven fabric, a flexible flexible film, or the like is broken at the perforation for separation. This is particularly effective for this type of cylindrical packaging material.

また、上述した実施形態では、筒状包材Ｐを円筒状に整形するマンドレル２３を、上側固定部２３ａ及び下側可動部２３ｂに分割し、筒状包材Ｐを分離用ミシン目Ｍで破断する際、一対の下側包材ホルダ２６によって、筒状包材Ｐにおける分離用ミシン目Ｍの包材送出方向の下流側の近傍を、マンドレル２３の下側可動部２３ｂの外周面に押し付けて保持した状態で、一対の下側包材ホルダ２６を、マンドレル２３の下側可動部２３ｂと共に引き下げるようにしているが、これに限定されるものではなく、筒状包材が嵌挿された状態で、包材送出方向に進退可能に支持された内部可動体を、マンドレルの下流側に別途設け、筒状包材における分離用ミシン目の包材送出方向の下流側の近傍を、一対の包材ホルダによって、この内部可動体に押し付けて保持した状態で、一対の包材ホルダを、内部可動体と共に引き下げるようにしてもよい。   Further, in the above-described embodiment, the mandrel 23 for shaping the cylindrical packaging material P into a cylindrical shape is divided into the upper fixed portion 23a and the lower movable portion 23b, and the cylindrical packaging material P is broken at the perforation M for separation. In this case, the pair of lower packaging material holders 26 press the vicinity of the separation perforation M in the tubular packaging material P on the downstream side in the packaging material delivery direction against the outer peripheral surface of the lower movable portion 23b of the mandrel 23. While holding the pair of lower packaging material holders 26 together with the lower movable portion 23b of the mandrel 23, the present invention is not limited to this, and a state in which a tubular packaging material is inserted and inserted Then, an internal movable body supported so as to be able to advance and retreat in the packaging material delivery direction is separately provided on the downstream side of the mandrel, and the vicinity of the downstream side in the packaging material delivery direction of the separation perforation in the cylindrical packaging material This internal movable body is pushed by the material holder. While holding put, a pair of packaging material holder, may be lowered with an internal movable member.

また、包材ホルダや包材クランパは、必ずしも、一対に限定されるものではなく、円筒状に整形された筒状包材を、三方または四方から押さえ付けたり、三箇所以上で把持したりすることも可能であり、マンドレルも円筒状に限定されるものではなく、角ボトルの場合は、角筒状といった具合に、容器（ボトル）形状に応じて、適宜、変更することができる。   In addition, the packaging material holder and the packaging material clamper are not necessarily limited to a pair, and the cylindrical packaging material shaped into a cylindrical shape is pressed from three or four directions, or held at three or more locations. In addition, the mandrel is not limited to a cylindrical shape, and in the case of a square bottle, the shape can be appropriately changed according to the shape of the container (bottle), such as a rectangular tube shape.

また、上述した実施形態では、筒状包材Ｐの破断端を包材クランパ２４によって把持すると共に、分離用ミシン目Ｍの下側近傍を下側包材ホルダ２６によってマンドレル２３の下側可動部２３ｂに押さえ付けた状態で、包材クランパ２４と下側包材ホルダ２６とを、同期をとりながら、引き下げることで、筒状包材Ｐを分離用ミシン目Ｍで破断するようになっているが、これに限定されるものではなく、筒状包材Ｐを分離用ミシン目Ｍで破断するだけであれば、分離用ミシン目Ｍの下側近傍を下側包材ホルダ２６によってマンドレル２３の下側可動部２３ｂに押さえ付けた状態で、下側包材ホルダ２６だけをを引き下げることで、筒状包材Ｐを分離用ミシン目Ｍで破断することも可能であり、この場合も、破断された筒状包材Ｐの型くずれを防止することができる。   In the above-described embodiment, the broken end of the cylindrical packaging material P is gripped by the packaging material clamper 24, and the lower movable portion of the mandrel 23 is disposed near the lower side of the separation perforation M by the lower packaging material holder 26. The cylindrical packaging material P is broken at the separation perforation M by pulling down the packaging material clamper 24 and the lower packaging material holder 26 while synchronizing with each other in a state of being pressed down to 23b. However, the present invention is not limited to this, and if the cylindrical packaging material P is only to be broken by the separation perforation M, the lower vicinity of the separation perforation M is placed on the mandrel 23 by the lower packaging material holder 26. It is also possible to break the cylindrical packaging material P at the separation perforation M by pulling down only the lower packaging material holder 26 while being pressed against the lower movable portion 23b. The shape loss of the cylindrical packaging material P It is possible to stop.

また、上述した各実施形態では、破断された筒状包材Ｐの型くずれを防止するために、分離用ミシン目Ｍの下側近傍を下側包材ホルダ２６によってマンドレル２３の下側可動部２３ｂに押さえ付けた状態で、下側包材ホルダ２６をマンドレル２３の下側可動部２３ｂと共に引き下げるようにしているが、下側包材ホルダ２６のように、筒状包材Ｐを完全に保持するのではなく、分離用ミシン目Ｍの下側近傍を各種支え手段によって支えながら、筒状包材Ｐの破断端を把持している包材クランパ２４を引き下げることによって、筒状包材Ｐを分離用ミシン目Ｍで破断することも可能である。筒状包材Ｐの分離用ミシン目Ｍの下側近傍を支える方法としては、筒状包材をフリーローラ等によってマンドレル等の内部受け部材との間に挟み込んだり、マンドレルによって円筒状に整形された筒状包材の外側に、微少な隙間を開けて吸引部材を配置し、この吸引部材によって、全周にわたって、または、部分的に、筒状包材Ｐを吸着したり、筒状包材Ｐの外側から空気を吹き付けることで、マンドレル等の内部受け部材に筒状包材を押し付けるようにしたりすることが考えられる。   Further, in each of the above-described embodiments, the lower movable portion 23b of the mandrel 23 is placed near the lower side of the separation perforation M by the lower packaging material holder 26 in order to prevent the broken cylindrical packaging material P from being deformed. The lower packaging material holder 26 is pulled down together with the lower movable portion 23b of the mandrel 23 in a state where it is pressed down, but the cylindrical packaging material P is completely held like the lower packaging material holder 26. Instead, the tubular packaging material P is separated by pulling down the packaging material clamper 24 holding the broken end of the tubular packaging material P while supporting the lower side of the separation perforation M with various support means. It is also possible to break at the perforation M. As a method of supporting the lower vicinity of the perforation M for separation of the cylindrical packaging material P, the cylindrical packaging material is sandwiched between internal receiving members such as a mandrel by a free roller or the like, or shaped into a cylindrical shape by a mandrel. A suction member is arranged outside the cylindrical packaging material with a small gap, and the cylindrical packaging material P is adsorbed over the entire circumference or partially by this suction member. By blowing air from the outside of P, it may be possible to press the cylindrical packaging material against an internal receiving member such as a mandrel.
