ル（92a, 92b)と、 第 1チェ ン（93a)にとつて供給口-リング装置（60)の供給口-ラ- (61)を回転させると、 供給口-ラ-（61 )の表面に容器（50)内の溶融コ-ティング剤 (52)が塗られる。 また、 供給ロ ラ-（61)に付いた溶融コ-ティング剤（52)は、 仲介口-ラ- (62)に よって成形口-リング装置（70)のヒ -ティング'口-ラ-（71)に供給される。 ここで、 容器（50)の貯蔵室（54)に貯蔵された熱媒体油（53)は、 溶融コ-ティング 剤（52)の温度を約 110〜120°C程度に維持させ、 供給口-リング装置（60)の供給ロ - ラ-（61)に溶融コ-ティング剤（52)が円滑に、 かつ均一に塗られるようにする。 また、 図 2及び図 3に示されたように、 シ-ト（30)と溶融コ-ティング剤（52)が供 給される状態において、 駆動装置（90)のモ-タ（91)が駆動されると、 モ タ（91 )の 駆動力が第 1チェ-ン（92a)と、 これに嚙み合われて駆動力を伝達する第 3スプロ ケッ ト 'ホイ-ル（92c)及び第 2チェ-ン（93b)によって、 成形口-リング装置（70)の ヒ-ティング '口-ラ-（71)を回転させる。 そして、 ヒ -ティ ング'口-ラ- (71)の回転運動は、 第 1原動及び従動歯車 (94a, 94b)によって押送口-ラ-（72)に伝達される。 従って、 成形口-リング装置（70)のヒティン-グ '口-ラ-（71 )と、 押送口-ラ-（72) がー緒に回転しながら、 共同で供給トラック（40)から供給されるシ-ト（30)を移送 させると同時に、 シ-ト（30)の表面に溶融コ-ティング剤（52)をコ-ティングする。 この時、 容器（50)の貯蔵室（54)からヒティング ·口 -ラ-（71 )の中空（71 a)に供給 管（73)を通って熱媒体油（53)が供給され、 このことによってヒティング ·口 -ラ- (71 )の温度が溶融コ-ティング剤（52)をコ-ティングするのに適切な温度となるよ う維持され、 コ-ティングが円滑でかつ均一に行われる。 一方、 駆動装置（90)のモ-タ（91 )が駆動され、 第 3スプロケット 'ホイ-ル（92c)が 回転されると、 第 3スプロケット 'ホイ -ノレ（92c)の回転運動は、 第 4スプロケッ ト' ホイ -ノレ（92d)と第 3チェ-ン（93c)によつて移送口 -リング装置（80)の原動口-ラ- (81 )に伝達されて原動口-ラ-（81)が回転されるが、 この原動口-ラ-（81)の回転運 動は、 第 2原動及び従動歯車（95a, 95b)の回転運動によって、 移送口-リング装置 (80)の従動口 -ラ-（82)に伝達される。 従って、 移送口-リング装置（80)の原動及び従動口-ラ-（81、82)は、 一緒に回転 しながら、 共同で成形口-リング装置（70)からコ-ティング処理されたコ-ティン グ…ン -ト（30)が口-ラ-に巻き込まれるような現象を防止しながら移送するように なる。 そして、 成形及び移送口-リング装置（70、80)のそれぞれの間隔及び高さは、 油 圧ァクチユエ-タ-（100)の駆動によって、 口-ド（101 )を前後運動させてコ-ティン グの厚さが調節できるもので、 その厚さは約 5〜20 μ m程度に維持させることが望 ましい。 TECHNICAL FIELD The present invention relates to a sheet coating machine, and more particularly, to a sheet coating machine using a melting coating agent.

BACKGROUND ART Conventionally, the surface of sheets such as various books, catalogs, and wrapping papers has been subjected to various coatings to prevent the surface of the sheets from being altered or damaged by air, water, and chemicals. Came. There are several coating methods related to this, but the coating is performed while transferring the sheet and resin sheet, for example, polyethylene sheet, by the transfer port-ring device. There was a coating method called laminating. However, since this method cannot be recycled, its use is currently regulated. In addition, there are other coating methods called endless coating and ultraviolet coating, all of which use an organic solvent such as toluene, which deteriorates the working environment and makes it impossible to recycle waste. It was possible. A coating method called "clean coating" replaces organic solvents. Although water-soluble acryl'emulsion has been used, the working environment has improved as a result, but instead the waterproofness has decreased, and the coating process has to be repeated many times. There were serious disadvantages. In addition, the flexibility of the coating was reduced, and a longer curing time was required. Further, in order to improve such disadvantages, a sheet coating machine has been developed in which coating is performed using a solvent-free molten coating agent. Such a sheet 'coating machine stores a coating agent in a molten state in a container attached to the sheet' coating machine, and then transfers it through a number of nozzles. Some are configured to feed and coat the mouth-ring device. DISCLOSURE OF THE INVENTION However, in the conventional sheet coating machine as described above, the molten coating agent is supplied to the transfer port-ring device through the nozzles, so that the molten coating agent is supplied. During the process, there was a problem that deviation occurred. That is, when the molten coating agent is not supplied uniformly to each nozzle, or when one of a large number of nozzles is clogged, the supply deviation of the molten coating agent often occurs. This. As a result, there is a problem that the thickness and the surface condition of the sheet coating are not uniform, and many defective products come out. Further, the use of a large number of nozzles causes a problem. However, the number of parts involved increased, and the structure for connecting the container and each nozzle became complicated. In addition, there was a problem that not only did the productivity of the sheet coating machine decrease, but also the production cost increased. Therefore, the present invention has been devised in order to solve the conventional problems as described above, and an object of the present invention is to provide a sheet 'coating machine capable of obtaining a uniform surface. To provide. SUMMARY OF THE INVENTION An object of the present invention is to provide a sheet coating machine that not only improves productivity with a simple configuration but also saves production costs.

When the supply port (61) of the device (60) is rotated, the surface of the supply port (61) is coated with the molten coating agent (52) in the container (50). Further, the molten coating agent (52) attached to the supply roller (61) is supplied to the molding port-ring device (70) by the intermediate port port (62). 71). Here, the heating medium oil (53) stored in the storage room (54) of the container (50) maintains the temperature of the molten coating agent (52) at about 110 to 120 ° C, The supply roller (61) of the ring device (60) is smoothly and uniformly coated with the molten coating agent (52). Further, as shown in FIGS. 2 and 3, when the sheet (30) and the molten coating agent (52) are supplied, the motor (91) of the driving device (90) is turned on. When driven, the driving force of the motor (91) is combined with the first chain (92a) and the third sprocket 'wheel (92c) and the third sprocket (92c), which transmit the driving force. By rotating the chain (93b), the heating port (71) of the forming port-ring device (70) is rotated. Then, the rotational motion of the gearing opening (71) is transmitted to the pusher opening (72) by the first driving and driven gears (94a, 94b). Therefore, the feeding port (70) and the feeding port (71) of the forming port-ring device (70) and the feeding port (72) rotate together and are supplied from the supply track (40) jointly. At the same time that the sheet (30) is transferred, a molten coating agent (52) is coated on the surface of the sheet (30). At this time, the heat medium oil (53) is supplied from the storage room (54) of the container (50) to the hollow (71a) of the hitting opening (71) through the supply pipe (73). By this, the temperature of the hitting mouth (71) is maintained at a temperature suitable for coating the molten coating agent (52), and the coating is performed smoothly and uniformly. On the other hand, when the motor (91) of the driving device (90) is driven and the third sprocket 'wheel (92c) is rotated, the rotational motion of the third sprocket' wheel (92c) is The four sprockets (92d) and the third chain (93c) are transmitted to the drive port-ring (81) of the transfer port-ring device (80) and are driven by the drive port (81). ) Is rotated. However, the rotational movement of the prime mover port (81) is caused by the rotation of the second prime mover and the driven gears (95a, 95b). It is transmitted to RA (82). Therefore, the prime mover and the follower-port rollers (81, 82) of the transfer port-ring device (80) are rotated together, and jointly coated from the forming port-ring device (70). The tinting (30) is transported while preventing the phenomenon of being caught in the mouth. The distance and height of each of the molding and transfer port-ring devices (70, 80) are adjusted by moving the port (101) back and forth by driving the hydraulic actuator (100). The thickness of the brush can be adjusted, and it is desirable that the thickness be maintained at about 5 to 20 μm.
ここで、 図 1及び図 4を参照しながらさらに詳しく説明すると、 コ -ティング- シ-ト（30a)は、 移送口-リング装置（80)によって排出トラック（1 10)へと移送、 排 出される。 また、 排出トラック（110)のリブ（111)はコ -ティング'シ-ト（30a)と排出トラッ ク（1 10)が接する接触面積を減少させ、 これによつてコ-ティング ·シ-ト（30a)が棑 出トラック（1 10)にくつ付く現象を防止し、 これによつてコ-ティング…ン -ト（30a) の排出が円滑に維持されるのである。  More specifically, referring to FIGS. 1 and 4, the coating sheet (30a) is transferred and discharged to the discharge truck (110) by the transfer port-ring device (80). It is. Also, the ribs (111) of the discharge truck (110) reduce the contact area where the coating 'sheet (30a) and the discharge truck (110) come into contact, and thus the coating sheet. (30a) is prevented from sticking to the output truck (110), whereby the discharge of the coating gate (30a) is smoothly maintained.
また、 排出トラック（110)を通過したコ -ティング'シ-ト（30a)は、 排出口-リン グ装置（130)の原動及び従動ローラー（131、 132)によつて排出される。 一方、 排出口-リング装置（130)の原動及び従動口 -ラ-（131、132)によって、 コ- ティング'シ-ト（30a)が排出される時、 冷却装置（120)の熱交換パイプ（121)に冷水 を供給させると、 熱交換パイプ（121)を通って流れる冷水は周りの熱を奪うように なる。 従って、 コ -ティング'シ-ト（30a)が冷却されながら硬化時間が大きく短縮され、 結果的にはシ-ト供給機（10)の効率が向上することになる。 そして、 硬化が完了したコ -ティング'シ-ト（30a)の表面は、 後処理によって光 沢もしくは無光沢に作ることができる。 このように、 被コ-ティング物は溶融コ-ティング剤（52)が、 供給口-リング装置 (60)と成形口-リング装置（70)によって、 シ-ト（30a)の表面に供給されながらコ- ティングされるので、 その表面が均一になり品質が著しく改善されるのである。 また、 供給口-リング装置（60)と成形口-リング装置（70)の構成が単純になり、 生産性が向上するだけでなく、 部品数の減少により生産費用が削減できる。 そして、 溶融コ-ティング剤（52)には、 有機溶剤を使用する必要がないため、 作 業環境が大幅に改善される。 The coating sheet (30a) having passed through the discharge truck (110) is discharged by the driving and driven rollers (131, 132) of the discharge port-ring device (130). On the other hand, when the coating sheet (30a) is discharged by the driving and driven ports (131, 132) of the discharge port-ring device (130), the heat exchange pipe of the cooling device (120) is discharged. When (121) is supplied with cold water, the cold water flowing through the heat exchange pipe (121) takes away the surrounding heat. Therefore, the curing time is greatly reduced while the coating sheet (30a) is being cooled, and as a result, the efficiency of the sheet feeder (10) is improved. Then, the surface of the cured coating 'sheet (30a) can be made glossy or matte by post-treatment. Thus, the material to be coated is supplied with the molten coating agent (52) to the surface of the sheet (30a) by the supply port-ring device (60) and the molding port-ring device (70). However, since the surface is coated, the surface becomes uniform and the quality is remarkably improved. In addition, the structure of the supply port-ring device (60) and the forming port-ring device (70) is simplified, which not only improves the productivity but also reduces the production cost by reducing the number of parts. Further, since it is not necessary to use an organic solvent for the molten coating agent (52), the working environment is greatly improved.
特に、 ロジンを主要成分として使用するので分解性が優れており、 またロジン 自体をリサイクルする時には、 サイジング剤として作用するため、 コ-ティング' シ-ト（30a)のリサイクルが容易になる。 ところが、 前記の実施例はあくまで本発明の望ましい実施例を説明したものに 過ぎず、 本発明の適用範囲はこのような範囲に限定されず、 同一思想の範囲内にお いては., ¾切に変形可能なものである。 従って、 本発明の実旌 に具体的に示された各構成要素の形状及ぴ構達ほ、 形して実施することも可能なものである。 産業上の利用可能性 以上、 - これま.で¾明したように、 本発明によるシ-ト コ -ティング機に'よる.と: . 溶融コ-ティング剤が供袷口-リング装置と成形口-リング装置によって、 シ -卜の表 面に均一に供給されてコ-ティング処理されるので、 被コ ティング物の品質が著し く改善されるのである.。,： さらに、 その構成が単純になり、 部品数が減ることによって生産性が向上し、 それと伴う生産費用が削減されるだけでなく、 硬化時間も短縮されて効率が大幅に 上がる。 In particular, rosin is used as a main component, so it has excellent decomposability. When rosin itself is recycled, it acts as a sizing agent, making it easier to recycle the coating sheet (30a). However, the above-described embodiment is merely an explanation of a preferred embodiment of the present invention, and the scope of the present invention is not limited to such a range, and within the scope of the same idea. It can be transformed into Therefore, it is also possible to form and implement each component specifically shown in the present invention.
