Description

本発明は、金型内において、成形と該成形品の表面への転写印刷を同時に行う成形同時印刷システムおよび転写印刷成形品の製造方法に関し、とくに成形品の両面に転写印刷が施される転写印刷成形品の製造に好適な、成形同時印刷システムおよび転写印刷成形品の製造方法に関する。   The present invention relates to a simultaneous molding printing system for simultaneously performing molding and transfer printing on the surface of a molded product in a mold, and a method for manufacturing a transfer printed molded product, and in particular, transfer in which transfer printing is performed on both sides of the molded product. The present invention relates to a simultaneous molding printing system and a transfer printing molded product manufacturing method suitable for manufacturing a printed molded product.

従来、成形時に成形と同時に成形品の両面に転写印刷を施す成形同時印刷システムとしては、図４に示すようなものが知られている。図４において、１００は金型を示している。金型１００は、射出成形機（図示略）に取り付けられており、固定型１０１と可動型１０２とから構成されている。固定型１０１、可動型１０２には、製品部を成形するキャビティ１０３、１０４が形成されている。固定型１０１内には成形機の射出ノズルの先端が当接される当接部１０５およびランナ１０６が設けられている。１０７は、後述の転写印刷用箔のための箔送り手段を示している。箔送り手段１０７は、成形機の上方に設けられる供給リール１０８と、成形機２の下方に設けられる巻取リール１０９とを有している。図４においては、箔送り手段１０７は可動型１０２側に配置されている。一対の引出ローラ１１０の回転により供給リール１０８から引き出された転写印刷用箔１１１は、固定型１０１と可動型１０２との間を通過し、一対の引取ローラ１１２の回転により巻取リール１０９に巻回されるようになっている。図４のシステムにおいては、供給リール１０８と一対の引出ローラ１１０とにより箔送り機構１１３が構成され、巻取リール１０９と一対の引取ローラ１１２とにより箔巻き取り機構１１４が構成されている。   Conventionally, as shown in FIG. 4, a simultaneous molding printing system that performs transfer printing on both sides of a molded product simultaneously with molding at the time of molding is known. In FIG. 4, reference numeral 100 denotes a mold. The mold 100 is attached to an injection molding machine (not shown) and includes a fixed mold 101 and a movable mold 102. The fixed mold 101 and the movable mold 102 are formed with cavities 103 and 104 for molding the product portion. In the fixed mold 101, an abutting portion 105 and a runner 106 with which the tip of an injection nozzle of the molding machine abuts are provided. Reference numeral 107 denotes a foil feeding means for a transfer printing foil described later. The foil feeding means 107 has a supply reel 108 provided above the molding machine and a take-up reel 109 provided below the molding machine 2. In FIG. 4, the foil feeding means 107 is arranged on the movable mold 102 side. The transfer printing foil 111 drawn from the supply reel 108 by the rotation of the pair of drawing rollers 110 passes between the fixed mold 101 and the movable mold 102, and is wound around the take-up reel 109 by the rotation of the pair of drawing rollers 112. It is supposed to be turned. In the system of FIG. 4, a foil feeding mechanism 113 is configured by the supply reel 108 and the pair of drawing rollers 110, and a foil winding mechanism 114 is configured by the winding reel 109 and the pair of drawing rollers 112.

転写印刷用箔１１１の一面１２０には、転写部１１５が設けられている。転写部１１５は、所定の間隔を置いて転写印刷用箔１１１の長手方向に複数配列されている。転写印刷用箔１１１は、図４に示すように、成形機の上方から下方に向けて送られるようになっている。   A transfer portion 115 is provided on one surface 120 of the transfer printing foil 111. A plurality of transfer portions 115 are arranged in the longitudinal direction of the transfer printing foil 111 at a predetermined interval. As shown in FIG. 4, the transfer printing foil 111 is sent from the upper side to the lower side of the molding machine.

箔送り手段１０７においては、箔送り機構１１３と箔巻き取り機構１１４とが同時に駆動されることにより、転写印刷用箔１１１が一定量送り出され、該転写印刷用箔１１１の転写部１０５が可動型１０２のキャビティ１０４に位置合せされるようになっている。なお、転写部１０５のキャビティ１０４への位置合せは、たとえばＣＣＤカメラによる画像処理等により正確に行われるようになっている。   In the foil feeding means 107, the foil feeding mechanism 113 and the foil winding mechanism 114 are simultaneously driven to feed a certain amount of the transfer printing foil 111, and the transfer portion 105 of the transfer printing foil 111 is movable. It is intended to be aligned with the cavity 104 of 102. Note that the alignment of the transfer unit 105 with respect to the cavity 104 is performed accurately by, for example, image processing using a CCD camera.

また、上記のような成形同時印刷システムにおいては、固定型１０１側にも上記箔送り手段１０７と略同様の構成の箔送り手段１１６が設けられている。そして、箔送り手段１１６の駆動により転写印刷用箔１１７の一面１２１上の転写部１１８が可動型１０１のキャビティ１０３に正確に位置合せされるようになっている。   Further, in the simultaneous molding and printing system as described above, the foil feeding means 116 having substantially the same configuration as the foil feeding means 107 is also provided on the fixed mold 101 side. The transfer unit 118 on the one surface 121 of the transfer printing foil 117 is accurately aligned with the cavity 103 of the movable mold 101 by driving the foil feeding means 116.

このような成形同時印刷システムにおいては、箔送り手段１０７と箔送り手段１１６とが駆動されることにより、転写部１１５、１１８がキャビティ１０３、１０４に位置合せされる。この状態で可動型１０２が図４の矢印方向に移動し型締めされる。そして、さらに、射出成形機から樹脂がキャビティ１０３、１０４に形成される空間内に充填され成形品１１９が成形される。また、同時に成形直後の成形品１１９側の熱により転写部１１５、１１８の絵柄が成形品１１９の両面に転写されるようになっている。   In such a simultaneous molding and printing system, the transfer units 115 and 118 are aligned with the cavities 103 and 104 by driving the foil feeding unit 107 and the foil feeding unit 116. In this state, the movable mold 102 moves in the direction of the arrow in FIG. Further, resin is filled into the spaces formed in the cavities 103 and 104 from the injection molding machine, and the molded product 119 is molded. At the same time, the design of the transfer portions 115 and 118 is transferred to both surfaces of the molded product 119 by heat on the molded product 119 side immediately after molding.

しかし、上記のような成形同時印刷システムにおいては、金型１００が型締めされた際、各転写印刷用箔１１１、１１７の幅方向の両端部は、金型１００の分割面１２４（パーティング面）に挟持されるので、射出された樹脂が転写印刷用箔１１１、１１７の幅方向の端部から反転写部側の面１２２、１２３側に流入するおそれがある。このような樹脂の流入が生じると、成形不良、転写不良を招来するおそれがある。
特開２００４−０７４４７６号公報 However, in the simultaneous molding and printing system as described above, when the mold 100 is clamped, both end portions in the width direction of the respective transfer printing foils 111 and 117 are separated by the dividing surfaces 124 (parting surfaces) of the mold 100. ), The injected resin may flow from the end in the width direction of the transfer printing foils 111 and 117 to the surfaces 122 and 123 on the side opposite to the transfer portion. If such an inflow of resin occurs, there is a risk of causing molding defects and transfer defects.

そこで本発明の課題は、上記のようなシステムにおける問題点に着目し、転写印刷用箔の反転写部側の面への樹脂の流入に起因する成形不良、転写不良のおそれを確実に解消可能な成形同時印刷システムおよび転写印刷成形品の製造方法を提供することにある。   Therefore, the object of the present invention is to focus on the problems in the system as described above, and reliably eliminate the possibility of molding defects and transfer defects due to the inflow of resin to the surface on the side opposite to the transfer portion of the transfer printing foil. Another object of the present invention is to provide a simultaneous molding printing system and a method for producing a transfer printing molded product.

In such a configuration, when the mold is clamped, the block body is pushed back to the fixed mold side or the movable mold side against the urging force of the spring, so that the end in the width direction of the transfer printing foil is easily sandwiched. it can. That is, at the time of molding, the end portion in the width direction of the transfer printing foil is sandwiched by a surface different from the dividing surface of the mold, so the surface on the side opposite to the transfer portion of the transfer printing foil at the time of injection Inflow of resin into the tube is reliably prevented. Further, when the mold is opened, a gap is formed between the block body and the fixed mold or the movable mold, so that the end in the width direction of the transfer printing foil can be easily inserted into the gap.

上記ブロック体にはランナーを形成することが可能である。   A runner can be formed on the block body.

また、上記ブロック体は、金型の分割面の一部を形成するものであることが好ましい。 Moreover, it is preferable that the said block body forms a part of division surface of a metal mold | die.

本発明に係る成形同時印刷システムには、複数の箔送り手段、たとえば２つの箔送り手段を配設することも可能である。箔送り手段を複数配設すれば成形品の両面に同時に転写印刷することも可能である。また、このような態様においては、箔送り手段同士の箔送り方向は互いに異なる方向に設定できる。たとえば、２つの箔送り手段を配設する態様においては、一方の箔送り手段の箔送り方向を、成形機の上下方向に設定した場合は、他方の箔送り手段の箔送り方向は成形機の幅方向に設定できる。   In the simultaneous molding and printing system according to the present invention, a plurality of foil feeding means, for example, two foil feeding means can be provided. If a plurality of foil feeding means are provided, it is possible to simultaneously transfer and print on both surfaces of the molded product. Moreover, in such an aspect, the foil feeding directions of the foil feeding means can be set in different directions.

箔送り手段５は成形機２の幅方向（図２の上下方向）の両側に設けられる供給リール２６と巻取リール２７とを有している。図２においては、箔送り手段５は固定型６側に配置されている。一対の引出ローラ２８により供給リール２６から引き出された転写印刷用箔２９は、固定型６と可動型７との間を通過し、一対の引取ローラ３０により巻取リール２７に巻回されるようになっている。本実施態様においては、供給リール２６と一対の引出ローラ２８とにより箔送り機構３１が構成され、巻取リール２７と引取ローラ３０とにより箔巻き取り機構３２が構成されている。このようにして転写印刷用箔２９は、図１に示すように、成形機２の幅方向に向けて送られるようになっている。   The foil feeding means 5 has a supply reel 26 and a take-up reel 27 provided on both sides of the molding machine 2 in the width direction (vertical direction in FIG. 2). In FIG. 2, the foil feeding means 5 is disposed on the fixed mold 6 side. The transfer printing foil 29 drawn from the supply reel 26 by the pair of drawing rollers 28 passes between the fixed mold 6 and the movable mold 7 and is wound around the take-up reel 27 by the pair of drawing rollers 30. It has become. In this embodiment, the supply reel 26 and the pair of drawing rollers 28 constitute a foil feeding mechanism 31, and the winding reel 27 and the drawing roller 30 constitute a foil winding mechanism 32. In this way, the transfer printing foil 29 is fed in the width direction of the molding machine 2 as shown in FIG.

転写印刷用箔２９の一面３３には、転写部３４が設けられている。転写部３４は、所定の間隔を置いて転写印刷用箔２９の長手方向に複数配列されている。   A transfer portion 34 is provided on one surface 33 of the transfer printing foil 29. A plurality of transfer portions 34 are arranged in the longitudinal direction of the transfer printing foil 29 at a predetermined interval.

箔送り手段５においても箔送り機構３１と箔巻き取り機構３２とが同時に駆動されることにより、転写印刷用箔２９が一定量送り出され、該転写印刷用箔２９の転写部３４が可動型６のキャビティ８に位置合せされるようになっている。なお、転写部３４のキャビティ８への位置合せは、たとえばＣＣＤカメラによる画像処理等により正確に行われるようになっている。   Also in the foil feeding means 5, the foil feeding mechanism 31 and the foil winding mechanism 32 are simultaneously driven to feed a certain amount of the transfer printing foil 29, and the transfer portion 34 of the transfer printing foil 29 is moved to the movable die 6. Are aligned with the cavities 8. The alignment of the transfer unit 34 with the cavity 8 is accurately performed by image processing using a CCD camera, for example.

本実施態様においては、固定型６には、金型３の型締め時に転写印刷用箔２９の幅方向の一端部を、金型３の分割面３６に対して折り曲げて固定型６との間に挟持するブロック体３５が設けられている。ブロック体３５には、射出樹脂の流路を形成するランナー３７が設けられており、ランナー３７を通過した樹脂は金型３の分割面３６上に形成されるゲート３８からキャビティ８、９により形成される空間内に射出されるようになっている。   In the present embodiment, the fixed mold 6 is formed by bending one end portion of the transfer printing foil 29 in the width direction with respect to the dividing surface 36 of the mold 3 when the mold 3 is clamped. A block body 35 sandwiched between the two is provided. The block body 35 is provided with a runner 37 that forms a flow path of the injection resin, and the resin that has passed through the runner 37 is formed by the cavities 8 and 9 from the gate 38 formed on the dividing surface 36 of the mold 3. It is designed to be injected into the space where

ブロック体３５は、固定型６に対してスプリング３９、４０を介して接続されている。ブロック体３５はスプリング３９、４０により固定型６から離間する方向に付勢されている。このため、型開き状態においては、ブロック体３５と固定型６との間に隙間４１が形成されるため転写印刷用箔２９の幅方向の端部４２を簡単に上記隙間４１に挿入できる。また、型締め時においては、スプリング３９、４０の付勢力に抗してブロック体３５は固定型側に押し戻されるので、隙間４１が消滅し転写印刷用箔２９の幅方向の端部４２が挟持される。本実施態様においては、ブロック体３５が金型３の分割面３６の一部を形成するようになっている。   The block body 35 is connected to the fixed mold 6 via springs 39 and 40. The block body 35 is biased in a direction away from the fixed mold 6 by springs 39 and 40. For this reason, since the gap 41 is formed between the block body 35 and the fixed mold 6 in the mold open state, the end 42 in the width direction of the transfer printing foil 29 can be easily inserted into the gap 41. At the time of mold clamping, the block body 35 is pushed back to the fixed mold side against the urging force of the springs 39 and 40, so that the gap 41 disappears and the end 42 in the width direction of the transfer printing foil 29 is held. Is done. In the present embodiment, the block body 35 forms a part of the dividing surface 36 of the mold 3.

本実施態様のような成形同時印刷システム１を用いて、本発明に係る転写印刷成形品の製造方法は以下のように実施される。箔送り手段４と箔送り手段５とが駆動されることにより、転写部２５、３４がキャビティ９、８に位置合せされる。この状態で可動型７が型締めされる。そして、さらに、射出成形機２から樹脂が射出されキャビティ８、９により形成される空間内に充填され成形品が成形される。また、同時に成形直後の成形品側の熱により転写部２５、３４の絵柄が成形品の両面に転写され転写印刷成形品４３が製造されるようになっている。   Using the simultaneous molding and printing system 1 as in this embodiment, the method for producing a transfer printing molded product according to the present invention is performed as follows. The transfer units 25 and 34 are aligned with the cavities 9 and 8 by driving the foil feeding unit 4 and the foil feeding unit 5. In this state, the movable mold 7 is clamped. Further, a resin is injected from the injection molding machine 2 and filled into a space formed by the cavities 8 and 9 to form a molded product. At the same time, the design of the transfer parts 25 and 34 is transferred to both surfaces of the molded product by the heat of the molded product immediately after molding, so that the transfer printed molded product 43 is manufactured.

このような方法においては、金型３の型締め時に転写印刷用箔２９の幅方向の端部４２は、金型３の分割面３６に対して折り曲げるようにブロック体３５と固定型６との間に挟持される。つまり、転写印刷用箔２９の幅方向の端部４２は、金型３の分割面３６とは異なる面に挟持されることになるので、射出時における転写印刷用箔２９の反転写部側の面４４への樹脂の流入が確実に防止される。   In such a method, when the mold 3 is clamped, the end portion 42 in the width direction of the transfer printing foil 29 is bent between the divided surface 36 of the mold 3 and the block body 35 and the fixed mold 6. Sandwiched between. That is, since the end 42 in the width direction of the transfer printing foil 29 is sandwiched by a surface different from the dividing surface 36 of the mold 3, Inflow of resin to the surface 44 is reliably prevented.

本発明に係る成形同時印刷システムおよび転写印刷成形品の製造方法は、たとえば成形品表面に文字、絵柄等が転写印刷される転写印刷成形品の製造において広範に使用することができる。   The simultaneous molding and printing system and the method for producing a transfer printing molded product according to the present invention can be widely used in the production of a transfer printing molded product in which, for example, characters, designs, etc. are transferred and printed on the surface of the molded product.
