小麦粉などの粉体を充填した包装袋は、その封止部に熱圧着性の接着層を備えており、封止部を加熱することにより接着層を溶融させて封止している。このような粉体充填包装袋の封止部の封止にはさまざまな機構を有した口封機が提案されている（例えば、特許文献１及び特許文献２）。
特許文献１の発明は、傾斜した姿勢で搬送される粉体充填包装袋の封止部を、搬送方向に沿って固定されたヒータにより、粉体充填包装袋の封止部を加熱及び冷却して封止させる構造の装置であり、特許文献２の発明は、可動式のヒータが、搬送されてくる粉体充填包装袋の封止部と接触し、加熱及び冷却して粉体充填包装袋を封止する構造の装置である。 A packaging bag filled with a powder such as wheat flour has a thermocompression bonding adhesive layer in its sealing part, and the sealing part is melted and sealed by heating the sealing part. Sealing machines having various mechanisms have been proposed for sealing the sealing portion of such powder-filled packaging bags (for example, Patent Document 1 and Patent Document 2).
In the invention of Patent Document 1, the sealing part of the powder-filled packaging bag is heated and cooled by the heater fixed along the transporting direction of the sealing part of the powder-filled packaging bag that is transported in an inclined posture. In the invention of Patent Document 2, the movable heater is in contact with the sealing portion of the powder-filled packaging bag being conveyed, heated and cooled, and then the powder-filled packaging bag It is the apparatus of the structure which seals.

しかし、特許文献１では、搬送される粉体充填包装袋の搬送方向の垂直方向の位置にズレなどがある場合には、封止部とヒータとの接触が不完全となり、それに伴い封止不良を発生する問題がある。また、特許文献２では、搬送されてきた粉体充填包装袋の封止部を可動式のヒータにより加熱するので、加熱時間を長くすることができ封止適性を向上させることができるが、粉体充填包装袋の搬送方向に対して垂直にヒータが設けられているので、ヒータは、封止部と局所的に接触することができないため、封止不良を発生させる場合がある。
特開２００１−１８０６２０号公報 特開昭６２−２２０４２５号公報 However, in Patent Document 1, when there is a deviation or the like in the vertical direction of the conveying direction of the powder-filled packaging bag to be conveyed, the contact between the sealing portion and the heater is incomplete, and accordingly, the sealing failure There is a problem that occurs. Moreover, in patent document 2, since the sealing part of the powder-filled packaging bag which has been conveyed is heated by a movable heater, the heating time can be lengthened and sealing suitability can be improved. Since the heater is provided perpendicular to the conveying direction of the body-filled packaging bag, the heater cannot locally contact the sealing portion, and may cause a sealing failure.

接着層１０２は、加熱すると溶融して粘着性を発生する熱圧着特性を有したヒートシール系の接着剤である。 As shown in FIG. 4A, the packaging bag 100 is a bag for packaging powder in which an adhesive layer 102 is provided on the sealing portion 101. When the powder is filled, the packaging bag 100 is shown in FIG. As shown, a powder-filled packaging bag 100-1 is obtained.
The adhesive layer 102 is a heat-sealing adhesive having a thermocompression bonding property that melts when heated and generates tackiness.

続いて、本実施例の口封機１０の使用方法について説明する。
包装袋１００に所定の量の粉体が充填されると、口封機１０は、図１（Ａ）に示すように、第１の搬送手段２０により粉体充填包装袋１００−１を姿勢傾斜手段３０へと搬送する（矢印Ａ）。姿勢傾斜手段３０は、搬送された粉体充填包装袋１００−１を、押し板３１により所定の角度の姿勢に傾斜させるとともに（矢印Ｂ）、第２の搬送手段４０へと押し出す（矢印Ｃ）。 Then, the usage method of the sealing machine 10 of a present Example is demonstrated.
When the packaging bag 100 is filled with a predetermined amount of powder, the sealing machine 10 tilts the powder-filled packaging bag 100-1 by the first conveying means 20 as shown in FIG. Transport to means 30 (arrow A). The attitude inclination means 30 inclines the conveyed powder-filled packaging bag 100-1 into an attitude of a predetermined angle by the push plate 31 (arrow B) and pushes it out to the second conveyance means 40 (arrow C). .

第２の搬送手段４０は、図５（Ａ）に示すように、押し出された粉体充填包装袋１００−１の傾斜姿勢を維持しながら、接触調整手段５０へと搬送する（矢印Ｄ）。接触調整手段５０のヒータ５１Ａは、粉体充填包装袋１００−１と接触する前は、上述したように所定の角度で傾斜した状態（初期状態）で静止しており、搬送されてきた粉体充填包装袋１００−１の封止部１０１が、図５（Ｂ）に示すように、局所的にヒータ５１Ａに接触すると、封止部１０１を押圧するとともに、接着層１０２を加熱して封止部１０１を接着する。このときに、ヒータ５１Ａは、傾斜機構５２Ａのエアシリンダ５２Ａ−１が縮むことにより傾斜し（矢印Ｅ１）、粉体充填包装袋１００−１の搬送（矢印Ｄ）を妨げることなく、封止部１０１を加熱することができる（加熱調整工程）。粉体充填包装袋１００−１がヒータ５１Ａを通過したら、エアシリンダ５２Ａ−１は、図５（Ｃ）に示すように、再び伸びて、ヒータ５１Ａを接触前の初期状態に戻す（矢印Ｆ１）。   As shown in FIG. 5A, the second conveying means 40 conveys the extruded powder-filled packaging bag 100-1 to the contact adjusting means 50 while maintaining the inclined posture (arrow D). The heater 51A of the contact adjusting means 50 is stationary in a state (initial state) inclined at a predetermined angle as described above before contacting the powder-filled packaging bag 100-1, and has been conveyed. As shown in FIG. 5B, when the sealing portion 101 of the filling packaging bag 100-1 locally contacts the heater 51A, the sealing portion 101 is pressed and the adhesive layer 102 is heated and sealed. The part 101 is adhered. At this time, the heater 51A is tilted by the contraction of the air cylinder 52A-1 of the tilt mechanism 52A (arrow E1), and does not hinder the conveyance (arrow D) of the powder-filled packaging bag 100-1 without blocking. 101 can be heated (heating adjustment step). When the powder-filled packaging bag 100-1 passes through the heater 51A, the air cylinder 52A-1 expands again as shown in FIG. 5C to return the heater 51A to the initial state before contact (arrow F1). .

続いて、第２の搬送手段４０は、粉体充填包装袋１００−１を接触調整手段５０のクーラユニット５０Ｂへ搬送し、ヒータ５１Ａにより加熱した粉体充填包装袋１００−１の封止部１０１を冷却する。所定の角度に傾斜した状態（初期状態）のクーラ５１Ｂは、図６（Ａ）に示すように、封止された粉体充填包装袋１００−１と接触すると、封止部１０１を押圧するとともに、加熱した封止部１０１を冷却する。このときに、クーラ５１Ｂは、傾斜機構５２Ｂのエアシリンダ５２Ｂ−１が縮むことにより傾斜し（矢印Ｅ２）、粉体充填包装袋１００−１の搬送（矢印Ｄ）を妨げることなく、封止部１０１を冷却することができる（冷却調整工程）。粉体充填包装袋１００−１がクーラ５１Ｂを通過したら、エアシリンダ５２Ｂ−１は、図６（Ｂ）に示すように、再び伸びて、クーラ５１Ｂを接触前の初期状態に戻し（矢印Ｆ２）、粉体充填包装袋１００−１の封止作業が完了となる。   Subsequently, the second conveying means 40 conveys the powder-filled packaging bag 100-1 to the cooler unit 50B of the contact adjusting means 50, and the sealing portion 101 of the powder-filled packaging bag 100-1 heated by the heater 51A. Cool down. As shown in FIG. 6A, the cooler 51B in a state inclined to a predetermined angle (initial state) presses the sealing portion 101 when it comes into contact with the sealed powder-filled packaging bag 100-1. Then, the heated sealing portion 101 is cooled. At this time, the cooler 51B is tilted by the contraction of the air cylinder 52B-1 of the tilting mechanism 52B (arrow E2), and does not hinder the conveyance (arrow D) of the powder-filled packaging bag 100-1 without blocking. 101 can be cooled (cooling adjustment step). When the powder-filled packaging bag 100-1 passes through the cooler 51B, the air cylinder 52B-1 extends again as shown in FIG. 6B to return the cooler 51B to the initial state before contact (arrow F2). The sealing operation of the powder-filled packaging bag 100-1 is completed.

なお、エアシリンダ５２Ａ−１及びエアシリンダ５２Ｂ−１（以下、総称してエアシリンダ５２−１）は、一定の圧力の空気が供給され、一定の力を発生させるように設定されており、その発生力を、ヒータ５１Ａ及びクーラ５１Ｂが粉体充填包装袋１００−１と接触したときに受ける力よりも小さくすることにより、粉体充填包装袋１００−１の搬送を妨げずに、エアシリンダ５２−１が縮むことができ、ヒータ５１及びクーラ５１Ｂが粉体充填包装袋１００−１を受け流すように傾斜することができる。粉体充填包装袋１００−１がヒータ５１Ａ及びクーラ５１Ｂを通過すると、ヒータ５１Ａ及びクーラ５１Ｂに加わる力が無くなるので、縮んだエアシリンダ５２−１が復元し、ヒータ５１及びクーラ５１Ｂを初期状態に戻している。   The air cylinder 52A-1 and the air cylinder 52B-1 (hereinafter collectively referred to as the air cylinder 52-1) are set so as to be supplied with a constant pressure of air and generate a constant force. By making the generated force smaller than the force received when the heater 51A and the cooler 51B come into contact with the powder-filled packaging bag 100-1, the air cylinder 52 does not interfere with the conveyance of the powder-filled packaging bag 100-1. -1 can be shrunk, and the heater 51 and the cooler 51B can be inclined to receive the powder-filled packaging bag 100-1. When the powder-filled packaging bag 100-1 passes through the heater 51A and the cooler 51B, since the force applied to the heater 51A and the cooler 51B is lost, the contracted air cylinder 52-1 is restored, and the heater 51 and the cooler 51B are returned to the initial state. It is returning.

本実施例の口封機１０は、粉体充填包装袋１００−１と、ヒータ５１Ａ及びクーラ５１Ｂとの傾斜角度を調整することにより、ヒータ５１Ａ及びクーラ５１Ｂと粉体充填包装袋１００−１の封止部１０１との接触時間及び接触面積を調整することができ、粉体充填包装袋１００−１の接着層１０２の加熱による溶融と、冷却による固着とを最適な条件で実施することができ、封止作業の確実性（信頼性）を向上させることができる。
また、上述したように、粉体充填包装袋１００−１の通過後にヒータ５１Ａ及びクーラ５１Ｂの傾斜姿勢が初期状態に戻るので、一定間隔を保って連続して粉体充填包装袋１００−１が搬送されたときに対しても、連続的に封止作業を実施することができる。 The sealing machine 10 of the present embodiment adjusts the inclination angle between the powder-filled packaging bag 100-1 and the heater 51A and the cooler 51B, so that the heater 51A and the cooler 51B and the powder-filled packaging bag 100-1 are connected. The contact time and contact area with the sealing part 101 can be adjusted, and the melting of the adhesive layer 102 of the powder-filled packaging bag 100-1 by heating and the fixing by cooling can be performed under optimum conditions. The reliability (reliability) of the sealing work can be improved.
Further, as described above, the inclined postures of the heater 51A and the cooler 51B return to the initial state after passing through the powder-filled packaging bag 100-1, so that the powder-filled packaging bag 100-1 is continuously maintained at a constant interval. Even when transported, the sealing operation can be carried out continuously.
