以下、添付図面に沿って、本発明「自動封緘装置」の実施形態について説明する。本発明に係る自動封緘装置１は、図１に示すように、基本的には搬送部２、剥離部３、及び、封緘部４によって構成されている。   Embodiments of the “automatic sealing device” of the present invention will be described below with reference to the accompanying drawings. As shown in FIG. 1, the automatic sealing device 1 according to the present invention basically includes a transport unit 2, a peeling unit 3, and a sealing unit 4.

搬送部２は、図２に示すような封筒１０を、搬送ステージ上のセット位置Ｓ（図１参照）から、剥離部３及び封緘部４へ順次搬送し、最終的に排紙テーブル２１まで搬送するものであり、モータの駆動力を受けて所定方向へ駆動するローラ（駆動ローラ）を含む複数のローラ２ａと、ローラ２ａの外側に周設された搬送ベルト２ｂと、搬送ベルト２ｂに対して所定の間隔を置いて取り付けられた複数の搬送爪２ｃとを有している。   The transport unit 2 sequentially transports the envelope 10 as shown in FIG. 2 from the set position S (see FIG. 1) on the transport stage to the peeling unit 3 and the sealing unit 4 and finally transports to the paper discharge table 21. A plurality of rollers 2a including a roller (driving roller) driven in a predetermined direction by receiving a driving force of a motor, a conveyor belt 2b provided around the roller 2a, and a conveyor belt 2b And a plurality of conveying claws 2c attached at predetermined intervals.

尚、図２に示す封筒１０は、封入物が本体１０ｂ内に導入され、本体１０ｂにおけるフラップ１０ａの折り返し予定位置に接着剤１０ｃが塗布され、その上に剥離テープ１１が貼着された状態で、かつ、フラップ１０ａを折り返すことによる「封緘」が行われていない状態（フラップ１０ａが折り返されていない状態）で、搬送部２のセット位置Ｓに供給される。   The envelope 10 shown in FIG. 2 is in a state in which the inclusion is introduced into the main body 10b, the adhesive 10c is applied to the flap 10a in the main body 10b at the position where the flap 10a is to be folded, and the release tape 11 is adhered thereon. In addition, the sheet is supplied to the set position S of the transport unit 2 in a state where “sealing” by folding the flap 10a is not performed (a state where the flap 10a is not folded).

剥離部３は、図２に示す封緘前の封筒１０の本体１０ｂに貼着されている剥離テープ１１を剥離させて、封筒１０から除去するためのものであり、図１及び図３に示すように、搬送中の封筒１０を押さえておくピンチローラ３ａと、高圧エアーの噴射により剥離テープ１１を封筒１０から吹き飛ばして除去するエアーノズル３ｂとを有している。   The peeling part 3 is for peeling the peeling tape 11 stuck to the main body 10b of the envelope 10 before sealing shown in FIG. 2 and removing it from the envelope 10, as shown in FIG. 1 and FIG. Further, a pinch roller 3a that holds the envelope 10 being conveyed and an air nozzle 3b that blows and removes the peeling tape 11 from the envelope 10 by jetting high-pressure air.

封緘部４は、剥離部３において剥離テープ１１が除去された封筒１０のフラップ１０ａを本体１０ｂ側に折り返して封緘を行うためのものであり、図４に示すように、封筒１０の下端部を押さえ込んで位置ずれを防止するバインダー４ａと、フラップ１０ａを折り返すフリップガイド４ｂと、折り返されたフラップ１０ａを本体１０ｂ及び接着剤１０ｃに押し付けるプレスバー４ｃとを有している。   The sealing part 4 is for folding and sealing the flap 10a of the envelope 10 from which the peeling tape 11 has been removed in the peeling part 3 to the main body 10b side, and as shown in FIG. It has a binder 4a that is pressed down to prevent positional deviation, a flip guide 4b that folds the flap 10a, and a press bar 4c that presses the folded flap 10a against the main body 10b and the adhesive 10c.

ここで、本発明に係る自動封緘装置１の動作態様について説明する。まず、図１に示すセット位置Ｓに封緘前の封筒１０（図２参照）を所定の向き（フラップ１０ａ及び剥離テープ１１の長手方向が搬送方向と一致する向き）でセットすると、搬送部２の搬送ベルト２ｂ及び搬送爪２ｃによって、セットされた封筒１０が剥離部３へ向かって搬送される。   Here, the operation | movement aspect of the automatic sealing apparatus 1 which concerns on this invention is demonstrated. First, when the envelope 10 (see FIG. 2) before sealing is set at a set position S shown in FIG. 1 in a predetermined direction (the direction in which the longitudinal direction of the flap 10a and the peeling tape 11 coincides with the transport direction), the transport unit 2 The set envelope 10 is conveyed toward the peeling unit 3 by the conveyance belt 2b and the conveyance claw 2c.

図３に示すように、剥離部３においては、封筒１０に貼着されている剥離テープ１１が通過する軌道の近傍に、多数のピンチローラ３ａが搬送方向に沿って直列的に配置されているほか、通過する剥離テープ１１に向かって高圧エアーを吹き付けることができる位置にエアーノズル３ｂが配置されている。   As shown in FIG. 3, in the peeling part 3, many pinch rollers 3a are arrange | positioned in series along the conveyance direction in the vicinity of the track | orbit through which the peeling tape 11 stuck to the envelope 10 passes. In addition, an air nozzle 3b is arranged at a position where high-pressure air can be blown toward the peeling tape 11 that passes therethrough.

このため、剥離部３に搬送された封筒１０が、図３（１）において実線で示す位置（剥離テープ１１における搬送方向前方側の端部が、エアーノズル３ｂの近傍に達した位置）から、更に前方へ搬送されると、エアーノズル３ｂから噴射される高圧エアーによって、剥離テープ１１が、図３（２）に示すように、搬送方向前方側から次第に剥がされていき、図３（２）において一点鎖線で示す位置（剥離テープ１１における搬送方向後方側の端部が、エアーノズル３ｂの近傍に達した位置）まで封筒１０が搬送されると、剥離テープ１１が封筒１０から完全に剥がされて、吹き飛ばされることになる。   For this reason, the envelope 10 conveyed to the peeling unit 3 is from the position indicated by the solid line in FIG. 3 (1) (the position where the end of the peeling tape 11 on the front side in the conveyance direction has reached the vicinity of the air nozzle 3b). When transported further forward, the release tape 11 is gradually peeled off from the front side in the transport direction, as shown in FIG. 3 (2), by the high-pressure air jetted from the air nozzle 3b. When the envelope 10 is conveyed to the position indicated by the alternate long and short dash line (the position where the end of the peeling tape 11 on the rear side in the conveying direction reaches the vicinity of the air nozzle 3b), the peeling tape 11 is completely peeled off from the envelope 10. Will be blown away.

尚、剥離テープ１１だけでなく、封筒１０自体も、エアーノズル３ｂの近傍を通過する際に高圧エアーを浴びることになるが、ピンチローラ３ａが、いずれも下方（搬送ステージ側）へ付勢され、エアーノズル３ｂを基準とする搬送方向の前方及び後方へ広い範囲にわたって配置されているため、搬送中の封筒１０は、その搬送方向前方側の部分がエアーノズル３ｂによる高圧エアーの影響を受け始める位置から、搬送方向後方側の部分が高圧エアーの影響から脱する位置までの間、これらのピンチローラ３ａによって搬送ステージ側に常時押し付けられることになるため、位置ずれが生じることはなく、適正なライン上を搬送されることになる。   Note that not only the release tape 11 but also the envelope 10 itself is exposed to high-pressure air when passing through the vicinity of the air nozzle 3b, but the pinch rollers 3a are all urged downward (on the conveyance stage side). Since the envelope 10 being transported is arranged over a wide range in the transport direction with respect to the air nozzle 3b as a reference, the front portion in the transport direction of the envelope 10 being transported begins to be affected by high-pressure air from the air nozzle 3b. From the position to the position where the portion on the rear side in the conveyance direction is removed from the influence of the high-pressure air, the pinch roller 3a is always pressed against the conveyance stage side. It will be transported on the line.

剥離部３において剥離テープ１１が剥がされた封筒１０は、接着剤１０ｃが露出した状態で、搬送ベルト２ｂ及び搬送爪２ｃにより封緘部４へ搬送される。封筒１０が封緘部４内の所定の位置まで搬送されると、搬送部２（ローラ２ａ、搬送ベルト２ｂ、及び、搬送爪２ｃ）は一旦停止し、搬送された封筒１０に対して封緘が行われる。   The envelope 10 from which the peeling tape 11 has been peeled off at the peeling portion 3 is conveyed to the sealing portion 4 by the conveying belt 2b and the conveying claws 2c with the adhesive 10c exposed. When the envelope 10 is conveyed to a predetermined position in the sealing unit 4, the conveyance unit 2 (the roller 2 a, the conveyance belt 2 b, and the conveyance claw 2 c) is temporarily stopped, and sealing is performed on the conveyed envelope 10. Is called.

封緘部４においては、図４に示すように、バインダー４ａによる封筒１０の固定、フリップガイド４ｂによるフラップ１０ａの折り返し、プレスバー４ｃによるプレス、が順次実行される。より詳細には、封緘部４に封筒１０が搬送される際、バインダー４ａ、フリップガイド４ｂ、及び、プレスバー４ｃは、図４（１）に示す基準位置にある。即ち、バインダー４ａは、搬送ガイド２ｅ（搬送ステージ２ｄ上を搬送される封筒１０の下端の軌道に沿って配置され、封筒１０の搬送方向及び向き等をガイドする）の近傍であって、封筒１０の下端部の上方に位置し、フリップガイド４ｂは、フラップ１０ａの下側となる位置にあり、プレスバー４ｃは、封筒１０に塗布されている接着剤ｃの上方（フラップの折り返し予定位置の上方）に位置している。   In the sealing unit 4, as shown in FIG. 4, the fixing of the envelope 10 by the binder 4a, the folding back of the flap 10a by the flip guide 4b, and the pressing by the press bar 4c are sequentially performed. More specifically, when the envelope 10 is conveyed to the sealing unit 4, the binder 4a, the flip guide 4b, and the press bar 4c are at the reference position shown in FIG. That is, the binder 4a is in the vicinity of the conveyance guide 2e (arranged along the lower end track of the envelope 10 conveyed on the conveyance stage 2d and guides the conveyance direction and direction of the envelope 10). The flip guide 4b is located on the lower side of the flap 10a, and the press bar 4c is located above the adhesive c applied to the envelope 10 (above the flap folding expected position). ).

封筒１０が封緘部４内の所定の位置まで搬送され、搬送部２が停止すると、図４（２）に示すように、まず、バインダー４ａが下降して、封筒１０の下端部を搬送ステージ２ｄに押し付けて封筒１０を固定する。これにより、封緘工程中における封筒１０の位置ずれが防止される。   When the envelope 10 is conveyed to a predetermined position in the sealing unit 4 and the conveyance unit 2 is stopped, as shown in FIG. 4 (2), first, the binder 4a is lowered, and the lower end portion of the envelope 10 is moved to the conveyance stage 2d. To fix the envelope 10. Thereby, the position shift of the envelope 10 during the sealing step is prevented.

次に、フリップガイド４ｂが上昇し、フラップ１０ａが上方へ立ち上げられ、更にフリップガイド４ｂが、図４（２）に示す上昇位置から封筒１０の本体１０ｂ側へ移動して、図４（３）に示すように、フラップ１０ａが本体１０ｂの上側に折り返される。そして最後に、プレスバー４ｃが下降して、図４（４）に示すように、折り返されたフラップ１０ａが本体１０ｂ及び接着剤１０ｃに押し付けられる。   Next, the flip guide 4b is raised, the flap 10a is raised upward, and the flip guide 4b is further moved from the raised position shown in FIG. 4 (2) to the main body 10b side of the envelope 10, and FIG. ), The flap 10a is folded back to the upper side of the main body 10b. Finally, the press bar 4c is lowered, and the folded flap 10a is pressed against the main body 10b and the adhesive 10c as shown in FIG. 4 (4).

これで封緘工程が完了し、バインダー４ａ、フリップガイド４ｂ、プレスバー４ｃは、図４（１）に示す基準位置へ復帰する。封緘部４における封緘工程が完了すると、再び搬送部２が稼働し、封緘された封筒１０が、封緘部４から排紙テーブル２１（図１参照）へ搬送される。   Thus, the sealing process is completed, and the binder 4a, the flip guide 4b, and the press bar 4c are returned to the reference positions shown in FIG. When the sealing process in the sealing unit 4 is completed, the transport unit 2 is operated again, and the sealed envelope 10 is transported from the sealing unit 4 to the paper discharge table 21 (see FIG. 1).

尚、ここでは、本発明の一実施形態として、本体１０ｂにおけるフラップ１０ａの折り返し予定位置に接着剤１０ｃが塗布され、その上に剥離テープ１１が貼着された封筒１０（図２参照）を対象とする自動封緘装置１について説明したが、本発明は、フラップに接着剤が塗布され、その上に剥離テープが貼着された封筒を対象として自動封緘を行う装置として構成することもできる。   Here, as an embodiment of the present invention, an envelope 10 (see FIG. 2) in which an adhesive 10c is applied to a position where the flap 10a of the main body 10b is to be folded and a release tape 11 is attached thereon is used. However, the present invention can also be configured as an apparatus that performs automatic sealing on an envelope in which an adhesive is applied to a flap and a release tape is stuck on the flap.
