Description

この発明は、被包装体を被覆した熱収縮性フィルムからなる包材を加熱収縮させて被包装体に密着させる加熱収縮装置及びその加熱収縮装置によって包材を加熱収縮させた包装体に関する。   The present invention relates to a heating / shrinking apparatus that heat-shrinks a packaging material made of a heat-shrinkable film covering a packaged body and adheres the packaging material to the packaged body, and a packaged body that is heated and shrunk by the heating / shrinking apparatus.

例えば、図12(a)〜(c)に示す容器Vの胴部B及びキャップC部分を覆うように装着する、熱収縮性フィルムによって形成された筒状ラベルとしては、図13(a)に示すようなものがある。この筒状ラベルL1は、同図に示すように、開封する際にキャップC部分だけを剥ぎ取ることができるように、キャップCの下端位置に全周にわたって横ミシン目M1が形成されていると共に、筒状ラベルL1の上端から横ミシン目M1に至る平行な2本の縦ミシン目M2が形成されており、筒状ラベルL1の上端縁には、平行な2本の縦ミシン目M2の間に、突出した摘み部pが形成されている。こういった筒状ラベルL1は、容器Vの胴部B及びキャップC部分に被嵌し、これを加熱収縮させて胴部B及びキャップC部分に密着させることで容器Vに装着する。   For example, as a cylindrical label formed of a heat-shrinkable film that is mounted so as to cover the body B and the cap C of the container V shown in FIGS. 12 (a) to 12 (c), FIG. There is something to show. As shown in the figure, the cylindrical label L1 has a horizontal perforation M1 formed at the lower end position of the cap C over the entire circumference so that only the portion of the cap C can be peeled off when opened. Two parallel vertical perforations M2 extending from the upper end of the cylindrical label L1 to the horizontal perforation M1 are formed, and the upper end edge of the cylindrical label L1 is between the two parallel vertical perforations M2. In addition, a protruding knob portion p is formed. Such a cylindrical label L1 is fitted on the container V by being fitted on the body B and the cap C portion of the container V, and being heat-shrinked so as to be in close contact with the body B and the cap C portion.

こういった筒状ラベルL1は、同図(b)に示すように、容器Vの胴部B及びキャップC部分に被嵌し、同図(c)に示すように、これを加熱収縮させて胴部B及びキャップC部分に密着させることで容器Vに装着するが、こういった筒状ラベルL1が装着された容器Vを開封する場合は、まず、摘み部pを摘んで、2本の縦ミシン目M2を横ミシン目M1まで破断した後、横ミシン目M1を破断することにより、筒状ラベルL1におけるキャップC部分を剥ぎ取らなければならない(同図(d)参照)。   The cylindrical label L1 is fitted on the body B and the cap C of the container V as shown in FIG. 4B, and is heated and shrunk as shown in FIG. The container V is attached to the body B and the cap C by being in close contact with each other. When opening the container V to which such a cylindrical label L1 is attached, first, the knob p is picked and the two pieces are picked. After the vertical perforation M2 is broken to the horizontal perforation M1, the cap C portion of the cylindrical label L1 must be peeled off by breaking the horizontal perforation M1 (see FIG. 4D).

このように、こういった筒状ラベルL1では、縦ミシン目M2を破断した後に、横ミシン目M1を破断するといった具合に、2段階でミシン目を破断しなければならないので、開封作業性が悪いといった問題があり、係る問題を解消するため、図14(a)に示すような筒状ラベルLが提案されている。   Thus, in such a cylindrical label L1, the perforation must be broken in two stages, such as breaking the horizontal perforation M1 after breaking the vertical perforation M2, so that the opening workability is improved. In order to eliminate such a problem, a cylindrical label L as shown in FIG. 14A has been proposed.

この筒状ラベルL2は、同図に示すように、キャップCの下端位置を通る平行な2本の横ミシン目M1が全周にわたって形成されていると共に、この2本の横ミシン目M1を繋ぐように、摘み部pを形成する切目Gが形成されており、摘み部pを摘んで、2本の横ミシン目を全周にわたって破断するだけで、筒状ラベルLにおけるキャップC部分を剥ぎ取ることができるので、2段階でミシン目を破断しなければならない筒状ラベルL1に比べて開封作業性がよい。   As shown in the figure, the cylindrical label L2 is formed with two parallel perforations M1 passing through the lower end position of the cap C over the entire circumference and connecting the two horizontal perforations M1. Thus, the cut G that forms the knob portion p is formed, and the cap C portion of the cylindrical label L is peeled off only by picking the knob portion p and breaking the two horizontal perforations over the entire circumference. Therefore, the opening workability is better than that of the cylindrical label L1 in which the perforation must be broken in two stages.

しかしながら、摘み部pを形成するための大きな切目Gが形成された筒状ラベルLの場合、容器Vに被嵌して加熱収縮させると、同図(b)に示すように、切目Gに囲われている摘み部pが大きく収縮して、穴が開いたような状態になってしまい、体裁が悪いといった問題がある。   However, in the case of the cylindrical label L in which a large cut G for forming the knob portion p is formed, when it is fitted on the container V and is heat-shrinked, as shown in FIG. There is a problem that the picked portion p is greatly contracted and a hole is opened, and the appearance is poor.

従って、図14(a)に示すような開封作業性に優れた筒状ラベルLを採用することができず、依然として、図13(a)に示すような開封作業性の悪い筒状ラベルL1を採用しなければならないのが現状である。   Therefore, the cylindrical label L excellent in opening workability as shown in FIG. 14 (a) cannot be adopted, and the cylindrical label L1 having poor opening workability as shown in FIG. 13 (a) is still used. The current situation is that it must be adopted.

そこで、この発明の課題は、部分的に包材の熱収縮を抑えることができる加熱収縮装置及びその加熱収縮装置によって包材を加熱収縮させた包装体を提供することにある。   Accordingly, an object of the present invention is to provide a heating / shrinking device capable of partially suppressing the thermal shrinkage of the packaging material, and a packaging body in which the packaging material is heated / shrinked by the heating / shrinking device.

Label fitting And a delivery device 4 that receives the container LV), conveys it to the second container delivery position δ, and delivers it to the heat shrinking device 5 at the second container delivery position δ.

前記受渡装置4は、図2に示すように、ラベル被嵌容器LVを把持する開閉可能なクランパ4aと、このクランパ4aがラベル被嵌容器LVの把持を解除した状態で、ラベル被嵌容器LVを前方に押し出す進退可能なプッシャ4bとを備えた多数の搬送ユニット4Aが回転円盤4Bの同心円上に配設されたものであり、第1の容器受渡位置γにおいて、ラベル被嵌装置3によって搬送されてくるラベル被嵌容器LVをクランパ4aが把持し、その状態で、第2の容器受渡位置δまで搬送した後、第2の容器受渡位置δにおいて、クランパ4aによるラベル被嵌容器LVの把持を解除し、プッシャ4bがラベル被嵌容器LVを前方に押し出すことで、ラベル被嵌容器LVを加熱収縮装置5に引き渡すようになっている。   As shown in FIG. 2, the delivery device 4 includes an openable / closable clamper 4a for gripping the label-covered container LV, and the label-covered container LV with the clamper 4a released from gripping the label-covered container LV. A large number of transport units 4A each having a pusher 4b that can be moved forward and backward to push forward are disposed on the concentric circles of the rotating disk 4B, and transported by the label fitting device 3 at the first container delivery position γ. The clamper 4a grips the label-fitting container LV, and in that state, the label-fitting container LV is conveyed to the second container delivery position δ, and then the label-fitting container LV is grasped by the clamper 4a at the second container delivery position δ. Is released, and the pusher 4b pushes the label fitting container LV forward, so that the label fitting container LV is delivered to the heating and shrinking device 5.

前記加熱収縮装置5は、図1及び図2に示すように、ラベル被嵌容器LVを載せる多数の治具10と、この治具10を、第2の容器受渡位置δを通過するように、循環移動させる治具搬送手段20と、ラベル被嵌容器LVを載せた治具10が通過する際に、ラベルLを加熱することで、ラベルLを熱収縮させて容器Vに密着させる加熱トンネル30と、この加熱トンネル30から送出される、ラベルLが容器Vに密着した包装体Pを、治具10から取り出して搬出する包装体搬出手段40と、包装体Pが取り出された治具10が通過する際に、治具10を冷却する冷却トンネル50とを備えており、第2の容器受渡位置δでは、受渡装置4のプッシャ4bがラベル被嵌容器LVを押し出すことで、治具10にラベル被嵌容器LVが載せられるようになっている。   As shown in FIGS. 1 and 2, the heating and shrinking device 5 has a large number of jigs 10 for placing the label-fitting containers LV, and passes the jigs 10 through the second container delivery position δ. When the jig conveying means 20 for circulating movement and the jig 10 on which the label-covered container LV is placed pass, the label L is heated so that the label L is thermally shrunk to be in close contact with the container V. Then, the packaging body unloading means 40 for taking out the packaging body P sent out from the heating tunnel 30 and having the label L in close contact with the container V from the jig 10 and carrying it out, and the jig 10 from which the packaging body P has been taken out A cooling tunnel 50 that cools the jig 10 when passing, and at the second container delivery position δ, the pusher 4b of the delivery device 4 pushes the label fitting container LV to the jig 10 Label-covered container LV can be placed It has become.

前記治具10は、金属によって形成されており、図3に示すように、前方側が円弧状に形成されたベース板11と、このベース板11の上に設置された、ラベル被嵌容器LVを載せる略長方形状の載置台12と、この載置台12に後端部に立設された、載置台12に載せたラベル被嵌容器LVの胴部に沿って立ち上がる支持部材13とから構成されている。   The jig 10 is made of metal. As shown in FIG. 3, the jig 10 includes a base plate 11 whose front side is formed in an arc shape and a label fitting container LV installed on the base plate 11. It is comprised from the substantially rectangular mounting base 12 to mount, and the support member 13 which stood up along this trunk | drum of the label covering container LV mounted in the mounting base 12 standingly arranged by this mounting base 12 at the rear-end part. Yes.

前記支持部材13は、載置台12から立ち上がる幅狭の脚部14と、この脚部14の上端部に連設された、載置台12に載せたラベル被嵌容器LVの上半部が接触する幅広の支持部15とから構成されており、脚部14は、ラベル被嵌容器LVの下半部が接触しないように、その前面が支持部15の前面から僅かに後退している。   The support member 13 is in contact with a narrow leg portion 14 rising from the mounting table 12 and an upper half portion of the label fitting container LV placed on the mounting table 12 connected to the upper end portion of the leg portion 14. The leg portion 14 is slightly retracted from the front surface of the support portion 15 so that the lower half portion of the label fitting container LV does not come into contact with the wide support portion 15.

また、脚部14には、その上部前面に、後述する包装体搬出手段40の案内部材が嵌り込む嵌合溝14aが形成されており、支持部15の背面には、多数の縦溝15aと、これらの縦溝15aの下端部に繋がる、両端部が開放された1本の横溝15bとが形成されている。   In addition, the leg portion 14 is formed with a fitting groove 14a into which a guide member of a packaging body unloading means 40, which will be described later, is fitted on the upper front surface. A large number of vertical grooves 15a and , One horizontal groove 15b that is open at both ends and connected to the lower ends of the vertical grooves 15a is formed.

前記治具搬送手段20は、図1に示すように、第2の容器受渡位置δから包装体搬出手段40までの間、ラベル被嵌容器LVを載せた治具10を搬送する第一搬送ライン21と、包装体搬出手段40によって包装体Pが取り除かれた治具10を搬送する第2搬送ライン25と、第2搬送ライン25によって搬送されてくる治具10を所定のピッチで第2の容器受渡位置δに搬送するスターホイール26とから構成されており、第一搬送ライン21及び第2搬送ライン25は、それぞれ樹脂チェーンコンベアによって構成されている。   As shown in FIG. 1, the jig conveying means 20 is a first conveying line for conveying the jig 10 on which the label fitting container LV is placed between the second container delivery position δ and the package unloading means 40. 21, the second transport line 25 for transporting the jig 10 from which the package P has been removed by the package unloading means 40, and the jig 10 transported by the second transport line 25 at a predetermined pitch. It is comprised from the star wheel 26 conveyed to the container delivery position (delta), and the 1st conveyance line 21 and the 2nd conveyance line 25 are each comprised by the resin chain conveyor.

前記第一搬送ライン21は、図1及び図4(a)に示すように、その全長にわたって配設された主コンベア22と、加熱トンネル30の手前から包装体搬出手段40までの間、主コンベア22の両側に配設された一対の副コンベア23a、23bとから構成されており、ラベル被嵌容器LVを載せた治具10は、ベース板11の湾曲した前方側が副コンベア23a側に張り出すように、主コンベア22上に載せられている。   As shown in FIG. 1 and FIG. 4A, the first conveying line 21 includes a main conveyor 22 disposed over the entire length of the first conveying line 21 and the main conveyor 22 between the front of the heating tunnel 30 and the package carrying means 40. 22 is composed of a pair of sub-conveyors 23a and 23b, and the jig 10 on which the label fitting container LV is placed projects the curved front side of the base plate 11 to the sub-conveyor 23a side. Thus, it is placed on the main conveyor 22.

前記副コンベア23a、23bは、図4(a)に示すように、走向レール24、24の上面に形成された溝部に嵌り込んだ状態で設置されており、加熱トンネル30内では、走向レール24、24の溝部底面の高さを高くすることにより、同図(b)に示すように、主コンベア22との間に段差が形成されるようになっている。より詳細に説明すると、副コンベア23a、23bの始端部は主コンベア22と同一の高さ位置に設定されているが、加熱トンネル30の入口に近づくに従って徐々に高くなっていく。加熱トンネル30内では、所定の高さを維持しているが、加熱トンネル30の出口から徐々に低くなっていき、包装体搬出手段40の手前で主コンベア22と同一の高さ位置に戻るようになっている。   As shown in FIG. 4A, the auxiliary conveyors 23 a and 23 b are installed in a state where they are fitted into grooves formed on the upper surfaces of the running rails 24 and 24. By increasing the height of the bottom surface of the groove part 24, a step is formed with the main conveyor 22 as shown in FIG. More specifically, the start ends of the sub conveyors 23 a and 23 b are set at the same height as the main conveyor 22, but gradually increase as they approach the entrance of the heating tunnel 30. Although the predetermined height is maintained in the heating tunnel 30, it gradually decreases from the exit of the heating tunnel 30 and returns to the same height position as the main conveyor 22 in front of the package carrying means 40. It has become.

このため、前方側が副コンベア23a側に張り出すように、主コンベア22上に載せられている治具10は、ベース板11の前方側が副コンベア23aによって持ち上げられることで徐々に傾いていき、加熱トンネル30内では、載置台12に載せたラベル被嵌容器LVの上半部が支持部材13の支持部15にもたれかかるような状態になり、容器Vに被嵌されたラベルLの上半部が支持部15の前面に確実に接触することになる。従って、この副コンベア23a、23bが本願発明に言う「傾倒手段」に相当する。   For this reason, the jig 10 placed on the main conveyor 22 gradually tilts as the front side of the base plate 11 is lifted by the sub-conveyor 23a so that the front side projects to the sub-conveyor 23a side. In the tunnel 30, the upper half part of the label-covered container LV placed on the mounting table 12 is in a state of leaning against the support part 15 of the support member 13, and the upper half part of the label L fitted to the container V is placed.

The unloading conveyor 41 is a resin chain conveyor, and the outer peripheral surface of the body portion of the packaging body P placed on the jig 10. In the state where the packaging body P is gradually separated from the jig 10, and the suction conveyance unit 42 transfers the packaging body P from the jig 10 to the carry-out conveyor 41. When transferring, a guide plate 48 for assisting the package P is provided, and the upper surface of the mounting table 12 of the jig 10 is between the mounting table 12 of the jig 10 and the transfer conveyor 41. An auxiliary plate 49 for transferring to the carry-out conveyor 41 having the same height as the upper surface is provided.

前記吸引搬送ユニット42は、図1及び図5に示すように、原動プーリ44及び従動プーリ45に掛け渡された無端状の吸引搬送ベルト43と、この吸引搬送ベルト43に包装体Pを吸引保持させる吸引機構46とから構成されており、吸引搬送ベルト43には、その幅方向の中央部に長手方向に沿って所定間隔毎に多数の吸引孔(図示せず)が形成されている。   As shown in FIGS. 1 and 5, the suction conveyance unit 42 sucks and holds the endless suction conveyance belt 43 spanned between the driving pulley 44 and the driven pulley 45, and the package P on the suction conveyance belt 43. The suction conveyance belt 43 is formed with a plurality of suction holes (not shown) at predetermined intervals along the longitudinal direction in the central portion in the width direction.

前記吸引機構46は、吸引搬送ベルト43に沿って配置された吸引ボックス47と、この吸引ボックス47に形成された接続口に図示しないチューブ等を介して接続される真空ポンプ等の図示しない吸引装置とから構成されており、吸引ボックス47におけるガイドプレート48側の吸引搬送ベルト43との接触面には吸引口(図示せず)が開放されている。   The suction mechanism 46 includes a suction box 47 disposed along the suction conveyance belt 43 and a suction device (not shown) such as a vacuum pump connected to a connection port formed in the suction box 47 via a tube (not shown). A suction port (not shown) is opened on the contact surface of the suction box 47 with the suction conveyance belt 43 on the guide plate 48 side.

前記ガイドプレート48は、図1及び図5に示すように、加熱トンネル30側の端部側が楔状に形成されていると共に、幅方向の外側の側縁部が、移動する治具10の支持部材13(脚部14)に形成された嵌合溝14aに嵌り込むことで、包装体Pを吸引搬送ベルト43に沿って案内するようになっており、治具10に載せられた包装体Pが吸引搬送ユニット42の吸引搬送ベルト43に円滑かつ確実に吸引保持されるようになっている。   As shown in FIGS. 1 and 5, the guide plate 48 is formed in a wedge shape on the end side on the heating tunnel 30 side, and the side edge portion on the outer side in the width direction moves the support member of the jig 10. The package P is guided along the suction conveyance belt 43 by being fitted into the fitting grooves 14a formed in the 13 (leg portions 14), and the package P placed on the jig 10 is The suction and conveyance belt 43 of the suction and conveyance unit 42 is sucked and held smoothly and reliably.

前記冷却トンネル50は、図1及び図6に示すように、包装体搬出手段40の下流側に設置されたトンネル本体51と、このトンネル本体51に供給する冷風を生成する冷風生成ユニット54とから構成されており、トンネル本体51内には、冷風生成ユニット54によって生成された冷風を、ラベル被嵌容器LVの上半部が接触する治具10の支持部材30(支持部15)前面に吹き付ける第1ノズル52と、上方から支持部材30(支持部15)に吹き付ける第2ノズル53とが設置されている。   As shown in FIGS. 1 and 6, the cooling tunnel 50 includes a tunnel main body 51 installed on the downstream side of the packaging body unloading means 40, and a cold air generation unit 54 that generates the cold air supplied to the tunnel main body 51. In the tunnel main body 51, the cool air generated by the cool air generating unit 54 is blown to the front surface of the support member 30 (support portion 15) of the jig 10 with which the upper half of the label fitting container LV contacts. The 1st nozzle 52 and the 2nd nozzle 53 sprayed on the supporting member 30 (support part 15) from upper direction are installed.

前記第1ノズル52から吹き出された冷風は、支持部15の前面に吹き付けられるので、ラベル被嵌容器LVの上半部が接触する支持部15の前面を直接冷却することになるが、第2ノズル53から吹き出された冷風は、支持部15の外表面に沿って流れることで、支持部15を全体的に冷却するようになっており、特に、図7に矢印で示すように、支持部15の背面側を流れる冷風は、支持部15の背面に形成された多数の縦溝15a内に流入し、これらの縦溝15aの下端部に繋がる横溝15bを通って両側部に流出することになるので、支持部15全体を短時間で効率よく冷却することができる。   Since the cold air blown out from the first nozzle 52 is blown to the front surface of the support portion 15, the front surface of the support portion 15 with which the upper half of the label fitting container LV comes into contact is directly cooled. The cold air blown out from the nozzle 53 flows along the outer surface of the support portion 15 to cool the support portion 15 as a whole. In particular, as shown by arrows in FIG. The cold air flowing on the back surface side of 15 flows into a large number of vertical grooves 15a formed on the back surface of the support portion 15, and flows out to both sides through the lateral grooves 15b connected to the lower ends of these vertical grooves 15a. As a result, the entire support portion 15 can be efficiently cooled in a short time.

以上のように構成されたラベル装着システム1では、第2の容器受渡位置δにおいて、図11(b)に示す、摘み部pを形成する切目Gが形成されたラベルLの正面部分が、治具10の支持部15の前面側を向くような状態で、ラベル被嵌容器LVが治具10に載せられ、加熱トンネル30に送られる。なお、治具10は冷却トンネル50を通過する際、支持部材13の支持部15が主として冷却された状態で、第2の容器受渡位置δに供給される。   In the label mounting system 1 configured as described above, the front portion of the label L in which the cut G forming the knob p is formed as shown in FIG. 11B at the second container delivery position δ. The label fitting container LV is placed on the jig 10 so as to face the front side of the support portion 15 of the tool 10 and sent to the heating tunnel 30. When passing through the cooling tunnel 50, the jig 10 is supplied to the second container delivery position δ in a state where the support portion 15 of the support member 13 is mainly cooled.

ラベル被嵌容器LVが載せられた治具10は、図4(b)に示すように、ベース板11の前方側が副コンベア23aによって持ち上げられることにより傾いた状態で加熱トンネル30内を通過するので、加熱トンネル30内では、ラベル被嵌容器LVが重力によって支持部15にもたれかかり、ラベルLの正面部分における切目Gが形成された部分が冷却された支持部15の前面に確実に接触した状態になる。これによって、ラベルLにおける切目G部分の熱収縮だけが抑えられ、従来のように、切目Gに囲われている摘み部pが大きく収縮して、穴が開いたような状態になることがなく、図8に示すように、綺麗に仕上げることができる。   As shown in FIG. 4B, the jig 10 on which the label fitting container LV is placed passes through the heating tunnel 30 in an inclined state by lifting the front side of the base plate 11 by the sub-conveyor 23a. In the heating tunnel 30, the label fitting container LV leans against the support portion 15 due to gravity, and the portion where the cut G in the front portion of the label L is in contact with the cooled front surface of the support portion 15 reliably. Become. As a result, only the thermal contraction of the cut portion G in the label L is suppressed, and the knob portion p surrounded by the cut portion G is greatly contracted so that a hole is not opened as in the prior art. As shown in FIG. 8, it can be finished beautifully.

また、このラベル装着システム1に採用されている加熱収縮装置5では、重力を利用して、ラベルLにおける切目Gが形成された部分を冷却された支持部15の前面に接触させるようにしているので、ラベル被嵌容器LVを冷却された部材に押さえ付けるための手段を別途設ける必要がなく、加熱収縮装置5全体の構成が簡単になるという効果が得られる。   Moreover, in the heat contraction apparatus 5 employ | adopted as this label mounting system 1, the part in which the cut | interruption G in the label L was formed is made to contact the front surface of the cooled support part 15 using gravity. Therefore, it is not necessary to separately provide a means for pressing the label-fitting container LV against the cooled member, and the effect that the configuration of the entire heat shrinking device 5 is simplified can be obtained.

特に、このラベル装着システム1では、主コンベア22の両側に配設された副コンベア23aを昇降させることによって、治具10を傾けたり、初期状態に復帰させたりしているので、独立した傾倒手段や復帰手段を別途設ける必要がなく、治具10の傾倒や解除を円滑かつ効率よく行うことができる。   In particular, in this label mounting system 1, the jig 10 is tilted or returned to the initial state by moving up and down the sub-conveyors 23 a disposed on both sides of the main conveyor 22, so that independent tilting means are provided. Further, there is no need to provide a separate return means, and the jig 10 can be tilted and released smoothly and efficiently.

なお、上述した実施形態では、ラベルLにおける切目Gが形成された部分を支持部15の前面に確実に接触させるために治具10を15度程度傾けているが、これに限定されるものではなく、例えば、ラベル被嵌容器LVにおけるラベルLの切目G部分が真下を向くように、治具10を90度倒した状態で加熱トンネル30内を通過させることも可能である。ただし、ラベルLが容器Vに装着された包装体Pは、その後の取り扱いを考慮すると、起こした状態で搬出するのが望ましいので、治具10の傾斜角度は、上述した加熱収縮装置5のように、加熱トンネル30を通過した後で、治具10を起こしやすい角度に設定しておくことが望ましい。   In the above-described embodiment, the jig 10 is tilted by about 15 degrees in order to ensure that the portion of the label L where the cut G is formed is in contact with the front surface of the support portion 15. However, the present invention is not limited to this. For example, the jig 10 can be passed through the heating tunnel 30 while being tilted 90 degrees so that the cut line G of the label L in the label fitting container LV faces directly below. However, since the packaging body P with the label L attached to the container V is preferably taken out in consideration of the subsequent handling, the inclination angle of the jig 10 is the same as that of the above-described heating / shrinking device 5. In addition, after passing through the heating tunnel 30, it is desirable to set the angle at which the jig 10 is likely to be raised.

また、上述した各実施形態では、重力を利用してラベルLにおける切目Gが形成された部分を、冷却された治具10の支持部15の前面に接触させるようにしているが、これに限定されるものではなく、例えば、図9に示すように、冷水が循環供給される冷却パイプ10Aを加熱トンネル30内の搬送コンベア20A上に配設し、搬送コンベア20Aの搬送ベルト上にラベル被嵌容器LVを起立させて容器Vの底面を吸引することで、ラベル被嵌容器LVの搬送姿勢を保持した状態で、ラベルLの切目G部分を冷却パイプ10Aに摺接させながら、ラベル被嵌容器LVを搬送することも可能である。   Moreover, in each embodiment mentioned above, although the part in which the cut | interruption G in the label L was formed using gravity was made to contact the front surface of the support part 15 of the cooled jig | tool 10, it is limited to this. For example, as shown in FIG. 9, a cooling pipe 10A to which cold water is circulated and supplied is arranged on the conveying conveyor 20A in the heating tunnel 30, and the label is fitted on the conveying belt of the conveying conveyor 20A. While the container LV is erected and the bottom surface of the container V is sucked, the label-covered container is brought into sliding contact with the cooling pipe 10A while keeping the cut portion G of the label L in a state where the transport posture of the label-covered container LV is maintained. It is also possible to carry the LV.

また、上述した各実施形態では、2本の横ミシン目M1を繋ぐように、摘み部pを形成する湾曲した切目Gが形成されたラベルLを容器Vに装着する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、図10に示すように、2本の横ミシン目M1を繋ぐように、直線状の切目GAが形成されたラベルLAを容器Vに装着する場合についても適用することができる。   Moreover, although each embodiment mentioned above demonstrated the case where the label L in which the curved cut G which forms the knob | pick part p was formed so that the two horizontal perforations M1 might be connected to the container V was attached, For example, as shown in FIG. 10, the present invention is also applicable to a case where a label LA having a linear cut GA formed so as to connect two horizontal perforations M1 is attached to a container V. can do.

また、上述した各実施形態では、ラベルL、LAにおける切目G、GAが形成された部分の熱収縮を抑えるようにしているが、これに限定されるものではなく、熱収縮に伴うゆがみを防止するために特定の表示印刷部分の熱収縮を抑える場合にも、本発明の加熱収縮装置を採用することができる。   Further, in each of the above-described embodiments, the heat shrinkage of the portions where the cut lines G and GA in the labels L and LA are formed is not limited to this, and distortion caused by the heat shrinkage is prevented. Therefore, the heat shrinking device of the present invention can also be employed when suppressing heat shrinkage of a specific display printing portion.
