Description

本発明は、一般的にはポリプロピレンその他のプラスチックシート材にポケットを形成するためのＰＴＰ（プレス・スルー・パック）シート成形装置に関するものであり、さらに具体的には、包装すべき錠剤，カプセル等の被包装物の平面サイズ（包装状態での平面視におけるサイズ）の変化に対応できるＰＴＰシート成形装置に関するものである。   The present invention relates generally to a PTP (press-through-pack) sheet forming apparatus for forming pockets in polypropylene or other plastic sheet materials, and more specifically, tablets, capsules and the like to be packaged. The present invention relates to a PTP sheet forming apparatus that can cope with a change in the planar size of a packaged item (size in a plan view in a packaged state).

ＰＴＰ充填ラインの各装置は最近高性能化の要請が著しく、高速化（充填、打抜き、集積等）、自動化（包材供給、製品検査等）、省力化（部品交換の低減）が進行している。
このような要請に沿うものとして、発明者は後記の特許文献１に記載されているように、平形の成形金型を有する成形装置において、金型を取り替えることなく被包装物の厚みの変化に対応したポケットを成形できるＰＴＰシート成形装置を既に提案している。
前記開示の成形装置は、ポケットを最終的にメス型側で成形するプラグアシスタント構造に係るものであって、メス型の成形孔内にその内底部を構成する可動中子を設け、この可動中子を当該成形孔の開口部の方向へ進退させて適宜の位置にセットすることにより、プラスチックシート材に錠剤やカプセル等の被包装物のサイズに適合した深さのポケットを成形することができる。 Recently, there has been a significant demand for higher performance in each device of the PTP filling line, and speeding up (filling, punching, stacking, etc.), automation (packaging material supply, product inspection, etc.), and labor saving (reduction of parts replacement) have progressed. Yes.
In line with such a request, the inventor changed the thickness of the packaged object without changing the mold in a molding apparatus having a flat mold as described in Patent Document 1 described later. A PTP sheet forming apparatus capable of forming a corresponding pocket has already been proposed.
The molding apparatus disclosed above relates to a plug assistant structure for finally molding a pocket on the female mold side, and a movable core that forms the inner bottom portion is provided in a female mold molding hole. By moving the child back and forth in the direction of the opening of the molding hole and setting it at an appropriate position, a pocket having a depth suitable for the size of an article to be packaged such as a tablet or capsule can be formed on the plastic sheet material. .

しかし、一組の成形金型で被包装物の平面サイズの変化に対応したポケットを成形することができるＰＴＰ成形装置は、従来提案されていない。
したがって、被包装物の平面サイズが一定以上異なる場合には、成形金型を取り替える必要があるので設備費用が嵩む問題があった。
また、被包装物の平面サイズの相違が一定の範囲内である場合には、同じ成形金型により成形されるＰＴＰシートが使用されることがあるが、ポケットのサイズに対して被包装物の平面サイズが一定以上小さいと、包装された被包装物のポケット内でのおどり（動き）量が大きくなる（被包装物とポケットの適合性がわるくなる）ので、被包装物の品質低下を招き易いとともに包装品質が低下する問題があった。
特開２００２−３０１７６０号公報 However, a PTP molding apparatus capable of molding a pocket corresponding to a change in the planar size of an object to be packaged with a set of molding dies has not been proposed.
Therefore, when the planar sizes of the objects to be packaged are different from each other by a certain level, there is a problem that the equipment cost increases because it is necessary to replace the molding die.
In addition, when the difference in the planar size of the packaged object is within a certain range, a PTP sheet molded by the same molding die may be used. If the plane size is smaller than a certain level, the amount of movement (movement) in the pocket of the packaged item will increase (the compatibility between the item to be packaged and the pocket will be unsatisfactory), leading to a decrease in the quality of the item to be packaged. There was a problem that the packaging quality was lowered while being easy.
JP 2002-301760 A

本発明の解決課題は、成形金型を交換しなければプラスチックシート材に対し被包装物の平面サイズの変化に対応したポケットを成形することができないことである。   The problem to be solved by the present invention is that a pocket corresponding to a change in the planar size of an object to be packaged cannot be molded on a plastic sheet material unless the molding die is exchanged.

The plastic sheet material 5 is partially protruded by a predetermined amount, and the protruded portion of the plastic sheet material 5 is brought into close contact with the tip portion of the plug 3 by the pressure of compressed gas or the vacuum suction force. 5 is a device for forming a pocket 50 that substantially matches the outer shape of the distal end portion of the plug 3 (so-called male forming in which the pocket is finally formed on the plug side). The adjustment sleeve 3a is positionally regulated at least at a position where the tip end portion is retracted by a predetermined amount from the tip end portion of the plug 3 and a position where the tip end shape substantially matches the tip end shape of the plug 3. The main feature is that the position restricting means 4 is provided.

本発明に係るＰＴＰシート成形装置によれば、調整スリーブ３ａをその先端部がプラグ３の先端部から所定量後退した位置に位置規制することにより、プラスチックシート材５に平面サイズの小さいポケットを成形することができる。
他方、調整スリーブ３ａをその先端部形状がプラグ３の先端部形状と適合する位置に位置規制することにより、プラスチックシート材５に平面サイズの大きいポケットを形成することができる。
したがって、一組の成形金型で平面サイズが異なる少なくとも二種のポケットを成形することができるほか、前記プラグ３の突出量を調整すれば、深さの異なるポケットを成形することもできる。 According to the PTP sheet forming apparatus according to the present invention, the adjustment sleeve 3a is positioned at a position where the tip end of the adjustment sleeve 3a is retracted by a predetermined amount from the tip end of the plug 3, thereby forming a small pocket on the plastic sheet material 5. can do.
On the other hand, a pocket having a large planar size can be formed in the plastic sheet material 5 by restricting the position of the adjustment sleeve 3 a to a position where the tip shape matches the tip shape of the plug 3.
Accordingly, at least two types of pockets having different planar sizes can be formed by a set of molding dies, and pockets having different depths can be formed by adjusting the protruding amount of the plug 3.

以上のように構成された成形装置の作動について以下説明する。
図１のように、包装ラインの特定箇所に設置された第１の金型１と第２の金型２の間には、長尺のプラスチックシート材５が間欠的に供給される。
両金型１，２の間にプラスチックシート材５が供給されると、第１の金型１と、プラグ３を含む第２の金型２が図示しない進退手段により相対方向に必要量前進し、図３で示すように両金型１，２により当該プラスチックシート材５を挟む。次いで、１２０〜１３０℃程度に加熱されたプラグ３が突出量調整手段６によりあらかじめ設定された量だけ下降して、プラスチックシート材５の所要部分を第１の金型１の突出し用の孔１０側に所定量突き出す。その後ガスチャンバー１２内に圧縮ガスが供給され、そのガス圧力によりプラスチックシート材５の突出し部分が図４の（ａ）図で示すようにプラグ３の先端部に密着することにより、当該部分にポケット５０が加工され、ＰＴＰシート５ａの一コマが成形される。ＰＴＰシートの成形後、第１の金型１，第２の金型２及びプラグ３がもとの位置に復帰するとともに、同時に図示しないノックアウト手段によりＰＴＰシート５ａが両金型１，２から分離され、当該ＰＴＰシート５ａを含むプラスチックシート５はポケット成形部分である一コマ分包装ラインの下流側に移送される。以後、この成形工程が繰り返される。
成形されたＰＴＰシート５ａのポケット５０内には、図４の（ｂ）図で示すように後方ライン上で当該ポケット５０のサイズに適合するサイズの被包装物７が投入され、その上面には図示しないアルミ箔等の蓋シートが熱シールされる。
形成されるポケット５０の深さは、成形時のプラグ３の突出量の設定によって調整される。 The operation of the molding apparatus configured as described above will be described below.
As shown in FIG. 1, a long plastic sheet material 5 is intermittently supplied between the first mold 1 and the second mold 2 that are installed at specific locations in the packaging line.
When the plastic sheet material 5 is supplied between the two molds 1 and 2, the first mold 1 and the second mold 2 including the plug 3 are moved forward by a necessary amount in a relative direction by an advancing / retreating means (not shown). As shown in FIG. 3, the plastic sheet material 5 is sandwiched between both molds 1 and 2. Next, the plug 3 heated to about 120 to 130 ° C. is lowered by an amount set in advance by the protrusion amount adjusting means 6, and a required portion of the plastic sheet material 5 is moved into the protrusion hole 10 of the first mold 1. Project a certain amount to the side. After that, compressed gas is supplied into the gas chamber 12, and the protruding portion of the plastic sheet material 5 is brought into close contact with the tip of the plug 3 as shown in FIG. 50 is processed to form one frame of the PTP sheet 5a. After forming the PTP sheet, the first mold 1, the second mold 2 and the plug 3 are returned to their original positions, and at the same time, the PTP sheet 5a is separated from both molds 1 and 2 by a knockout means (not shown). Then, the plastic sheet 5 including the PTP sheet 5a is transferred to the downstream side of the packaging line for one frame which is a pocket forming portion. Thereafter, this molding process is repeated.
In the pocket 50 of the molded PTP sheet 5a, as shown in FIG. 4 (b), an article to be packaged 7 having a size suitable for the size of the pocket 50 on the rear line is placed. A lid sheet such as an aluminum foil (not shown) is heat-sealed.
The depth of the formed pocket 50 is adjusted by setting the protruding amount of the plug 3 at the time of molding.

図５の（ｄ）図のように、平面サイズの大きい被包装物７を包装するためのＰＴＰシート５ａを成形するときは、位置規制手段４により図５の（ｃ）図のように調整スリーブ３ａをその先端部形状がプラグ３の先端部形状と適合する位置まで前進させ、この状態で成形装置を前述の要領で作動させる。
プラグ３の先端部外周縁と調整スリーブ３ａの先端部にはほぼ一致するテーパ面が形成されているが、このテーパ面を含むプラグ３と調整スリーブ３ａとの先端部形状は、包装される被包装物７の形状に応じて選択される。 As shown in FIG. 5 (d), when forming a PTP sheet 5a for wrapping an article 7 having a large planar size, the position regulating means 4 adjusts the adjustment sleeve as shown in FIG. 5 (c). 3a is advanced to a position where the tip shape matches the tip shape of the plug 3, and in this state, the molding apparatus is operated as described above.
The outer peripheral edge of the tip of the plug 3 and the tip of the adjustment sleeve 3a have a tapered surface that is substantially coincident. The shape of the tip of the plug 3 and the adjustment sleeve 3a including the taper surface is to be packaged. It is selected according to the shape of the package 7.

前記実施形態のＰＴＰシート成形装置によれば、一組の金型により金型の取替えることなく、異なる平面サイズの被包装物７に対応するポケット５０を有するＰＴＰシート５ａを成形することができる。
また、プラグ３の突出量を調整することにより、ポケット５０の深さが種々異なるＰＴＰシートを成形することができる。
したがって、ポケット５０と被包装物７とのサイズが適合しないことによる被包装物の品質低下と包装品質の低下が防止される。 According to the PTP sheet forming apparatus of the embodiment, the PTP sheet 5a having the pockets 50 corresponding to the objects to be packaged 7 having different plane sizes can be formed without replacing the mold with a set of molds.
Further, by adjusting the amount of protrusion of the plug 3, PTP sheets with different depths of the pockets 50 can be formed.
Therefore, the deterioration of the quality of the packaged object and the deterioration of the packaging quality due to the mismatch between the sizes of the pocket 50 and the packaged object 7 are prevented.

前述の実施形態では、ポケット５０の最終的な成形を第１の金型１に供給される圧縮（高圧）ガスによって行っているが、この構成に代えて第２の金型２側から真空吸引する構成を採用することができる。   In the above-described embodiment, the final molding of the pocket 50 is performed by the compressed (high pressure) gas supplied to the first mold 1, but instead of this configuration, vacuum suction is performed from the second mold 2 side. It is possible to adopt a configuration to
