In FIG. 1, after sealing the bag mouth of the packaging bag 4 with the sealer 2A of the sealing device 2, By the delivery device 5, the packaging bag 4 can be turned 180 degrees and delivered from the rotary packaging device 1 to the feeding mechanism 6. After that, the wrapping bag 4 is conveyed linearly to the binding machine 3, and the opening end 4 </ b> A side of the wrapping bag 4 is folded into a bellows shape with the binding machine 3, and then the root of the opening end 4 </ b> A is bound with a binding band. Then, it is discharged by the carry-out conveyor 7.

受渡し装置5は、基台30上に支柱31を立設し、この支柱31上部に包袋4を180度旋回させて包袋4の表裏を反転させる旋回機構32が設けられている。前記支柱31は、円筒パイプ内部に回動軸31Aが嵌め込まれ、下端部にクランクロッド33が取り付けられ、このクランクロッド33を介してモータ(図示せず)の回転力を回動軸31Aに伝達して回動軸31Aを正逆方向に回動する。 The delivery device 5 is provided with a turning mechanism 32 that erects a support 31 on a base 30 and turns the packing bag 4 180 degrees above the support 31 to reverse the front and back of the packing bag 4. The support column 31 is fitted with a rotating shaft 31A inside a cylindrical pipe, and a crank rod 33 is attached to a lower end portion thereof, and the rotational force of a motor (not shown) is transmitted to the rotating shaft 31A via the crank rod 33. Then, the rotation shaft 31A is rotated in the forward and reverse directions.

図1に示すように、前記支柱31の上部に、旋回機構32の平行リンク機構34が取り付けられている。この平行リンク機構34は、平行に配置された第1のレバー34Aと第2のレバー34Bの先端が連結体34Cで連結され、第1と第2のレバー34A,34Bが円弧を描いて水平方向に揺動する。第1のレバー34Aは前記回動軸31Aの上部に水平に取り付けられている。第2のレバー34Bは支柱31の円筒パイプの上部に水平に固定されたアーム34Dの先端に、軸受け34Eが取り付けられ、この軸受け34Eの軸に取り付けられている。 As shown in FIG. 1, a parallel link mechanism 34 of a turning mechanism 32 is attached to the upper part of the support column 31. In the parallel link mechanism 34, the tips of the first lever 34A and the second lever 34B arranged in parallel are connected by a connecting body 34C, and the first and second levers 34A and 34B draw a circular arc in the horizontal direction. Rocks. The first lever 34A is horizontally attached to the upper part of the rotating shaft 31A. The second lever 34B has a bearing 34E attached to the tip of an arm 34D fixed horizontally to the upper part of the cylindrical pipe of the column 31, and is attached to the shaft of the bearing 34E.

第2のレバー34Bには、プレート35がネジにより固定されている。このプレート35の先端部に4本のステーボルト36が上方に突出して取り付けられ、その上端部にエアーで駆動するアクチュエータ37が取り付けられている。4本のステーボルト36で囲まれたプレート35の真ん中に軸受け38が取り付けられ、前記のアクチュエータ37の回転軸39が軸支されている。このアクチュエータ37の回転軸39はエアーによって作動し、正逆方向に回動する。 The plate 35 is fixed to the second lever 34B with screws. Four stay bolts 36 are attached to the front end of the plate 35 so as to protrude upward, and an actuator 37 driven by air is attached to the upper end of the plate 35. A bearing 38 is attached in the middle of the plate 35 surrounded by the four stay bolts 36, and the rotary shaft 39 of the actuator 37 is supported. The rotation shaft 39 of the actuator 37 is operated by air and rotates in the forward and reverse directions.

前記アクチュエータ37の回転軸39の下端部には、固定具40により長L字形の固定板41が垂直方向に立設している。この固定板41の下部の水平部には軸受け42が2個設けられ、この軸受け42に包袋4を挟持するグリップ43の板体が下方に開閉するように取り付けられている。長L字形の固定板41の垂直部にはエアーシリンダ44が取り付けられ、このエアーシリンダ44のロッド44Aが前記グリップ43の板体の一方に連結されている。なお前記グリップ43の板体同士は歯車により同じ角度だけ反対方向に回動する。 A long L-shaped fixing plate 41 is erected in the vertical direction by a fixture 40 at the lower end portion of the rotation shaft 39 of the actuator 37. Two bearings 42 are provided in the lower horizontal portion of the fixed plate 41, and a plate body of a grip 43 that sandwiches the wrapping bag 4 is attached to the bearing 42 so as to open and close downward. An air cylinder 44 is attached to a vertical portion of the long L-shaped fixing plate 41, and a rod 44 </ b> A of the air cylinder 44 is coupled to one of the plate bodies of the grip 43. The plates of the grip 43 are rotated in opposite directions by the same angle by a gear.

次に、前記受渡し装置5の作動を説明する。
支柱31の回動軸31Aがクランクロッド33を介してモータの動力により回動すると、それに従ってリンク機構34が円弧を描いて揺動する。図1に示すように、回動軸31Aの回動によりリンク機構34の平行リンクの第1のレバー34Aが回動し、第1のレバー34Aの回動により連結体34Cにより第の2レバー34Bが同時に回動する。
Next, the operation of the delivery device 5 will be described.
When the rotation shaft 31A of the column 31 is rotated by the power of the motor via the crank rod 33, the link mechanism 34 swings in a circular arc accordingly. As shown in FIG. 1, the first lever 34A of the parallel link of the link mechanism 34 is rotated by the rotation of the rotation shaft 31A, and the second second lever 34B is connected by the connecting body 34C by the rotation of the first lever 34A. Rotate at the same time.

第の2レバー34Bの回動によりプレート35を介して旋回機構32が揺動する。旋回機構32のグリップ43により、ロータリー式包装装置1のクランプアーム1Aに支持された包袋4を取りに行く場合は回動軸31Aを反時計周りに回転し、旋回機構32をクランプアーム1A側に近づける。その際、グリップ43は開いた状態にする。 The turning mechanism 32 swings through the plate 35 by the rotation of the second lever 34B. When the bag 43 supported by the clamp arm 1A of the rotary packaging device 1 is taken by the grip 43 of the turning mechanism 32, the turning shaft 31A is rotated counterclockwise, and the turning mechanism 32 is moved to the clamp arm 1A side. Move closer to At that time, the grip 43 is opened.

旋回機構32が包袋4の上方位置に到達すると、エアーシリンダ44を作動させてグリップ43を閉じて包袋4の開口上部を挟持する。グリップ43が包袋4を挟持した後、クランプアーム1Aのクランプ1aを開いて包袋4を放して旋回機構32側に受け渡す。 When the turning mechanism 32 reaches the upper position of the wrapping bag 4, the air cylinder 44 is operated to close the grip 43 and clamp the upper opening portion of the wrapping bag 4. After the grip 43 sandwiches the wrapping bag 4, the clamp 1a of the clamp arm 1A is opened to release the wrapping bag 4 and deliver it to the turning mechanism 32 side.

旋回機構32が包袋4を受け取ってから、回動軸31Aが時計方向に回動して送り機構6側に包袋4を受け渡そうとする。その搬送過程においてアクチュエータ37が作動して長L字形の固定板40を前記アクチュエータ37の回転軸39を中心にして180度回転する。この長L字形の固定板41の回転より、グリップ43に挟持された包袋4が180度旋回して、クランプアーム1Aに挟持されていた時の包袋4の裏表が逆転する。 After the turning mechanism 32 receives the wrapping bag 4, the rotation shaft 31 </ b> A rotates clockwise to try to deliver the wrapping bag 4 to the feed mechanism 6 side. In the conveying process, the actuator 37 operates to rotate the long L-shaped fixing plate 40 by 180 degrees around the rotation shaft 39 of the actuator 37. Due to the rotation of the long L-shaped fixing plate 41, the bag 4 held by the grip 43 turns 180 degrees, and the front and back sides of the bag 4 when held by the clamp arm 1A are reversed.

なお、包袋4の表裏を逆転させる必要がない場合は、アクチュエータ37を停止して旋回機構32の旋回を停止すれば、従来と同様な包袋4の受渡しができる。 If it is not necessary to reverse the front and back of the packaging bag 4, the delivery of the packaging bag 4 as in the conventional case can be performed by stopping the actuator 37 and stopping the turning of the turning mechanism 32.

次に、送り機構について説明する。
受渡し装置5から結束機3へは、送り機構6により包袋4を搬送する。送り機構6は、図2及び図3に示すように、受渡し装置5と結束機3の間に平行に敷設されたガイドロッド45上をベース46が往復移動する。往復移動は、図示しないモータの力をクランクアーム47を介してベース46に伝達されて行われる。
Next, the feeding mechanism will be described.
The bag 4 is conveyed from the delivery device 5 to the binding machine 3 by the feeding mechanism 6. As shown in FIGS. 2 and 3, in the feed mechanism 6, the base 46 reciprocates on a guide rod 45 laid in parallel between the delivery device 5 and the binding machine 3. The reciprocating movement is performed by transmitting the force of a motor (not shown) to the base 46 via the crank arm 47.

ベース46には、支軸48が2個配置され、各支軸48に、正面視において段状のアーム49が取り付けられ、そのアーム49の先端上方に図2の正面視T字形の挟持片50が水平に取り付けられている。一対のアーム49の下端部には、扇形の歯車51が取り付けられ、一方のアーム49をエアーシリンダ52で回動することにより、開いていた一対のアーム49の挟持片50が合掌状に閉じて包袋4を挟持する。この送り機構6の特徴は、被包装物が充填された包袋4の真ん中より少し上あたりを挟持片50で挟持して、アーム49で吊り下げた状態で搬送することである。このため、特許文献2のコンベアのように設置スペースを必要とせず、構造も比較的簡単である。なお、図2の符号53は振止めガイド板である。 Two support shafts 48 are arranged on the base 46, and a step-like arm 49 is attached to each support shaft 48 in front view, and a T-shaped sandwiching piece 50 in front view of FIG. Is mounted horizontally. A fan-shaped gear 51 is attached to the lower ends of the pair of arms 49, and when one arm 49 is rotated by the air cylinder 52, the holding pieces 50 of the pair of arms 49 that are opened are closed in a palm shape. Hold the wrapping bag 4. The feed mechanism 6 is characterized in that a portion slightly above the middle of the sachet 4 filled with the article to be packaged is sandwiched by the sandwiching piece 50 and transported while being suspended by the arm 49. For this reason, an installation space is not required like the conveyor of patent document 2, and a structure is also comparatively simple. In addition, the code | symbol 53 of FIG. 2 is a steadying guide plate.

図5は結束機の側面図を示している。実線で示す結束機3は、図5の状態ではメンテナンス及びリール(図示せず)交換時の作業性が悪くなる。この結束機3は取付け台60上にヒンジ61を介して結束機本体3Aが取り付けられている。通常の結束作業の場合、結束機本体3Aを立てた状態でロックする。メンテナンス及びリール交換時には、上部に取り付けたハンド3Bを引いて図5の二点鎖線で示す結束機本体3Aが倒れ掛かる状態まで寝かせると、メンテナンス及びリール交換作業が容易となる。
Next, the binding machine will be described.
FIG. 5 shows a side view of the binding machine. In the state shown in FIG. 5, the bundling machine 3 indicated by the solid line has poor workability during maintenance and reel (not shown) replacement. In the binding machine 3, the binding machine body 3 </ b> A is mounted on a mounting base 60 via a hinge 61. In the case of normal bundling work, the bundling machine body 3A is locked in a standing state. At the time of maintenance and reel replacement, the maintenance and reel replacement work is facilitated by pulling the hand 3B attached to the upper part and letting it stand until the binding machine body 3A shown by the two-dot chain line in FIG .

結束機本体3Aの前記受渡し装置5側に、揺動枠体62が設けられている。この揺動枠体62は、上部にエアーシリンダ63が接続し、そのエアーシリンダ63の接続部より少し下側をブラケット64に軸支し、これを支点として下側が揺動する。この揺動枠体62の下端部と、この下端部と対向する結束機本体3A側に、一対の蛇腹部65A、65Bからなる前記特許文献2と同様の蛇腹機構65を装備している。図5には図示していないが、蛇腹機構65は図7のようにジグザクな長尺なプラスチック板を、2本の金属棒に挿通し、駆動力により近接・離間移動する。なお、結束機本体3Aには、結束テープを包袋4の開口端部4Aに結束するための機構も備えているが、その詳細については省略する。 A swing frame body 62 is provided on the side of the delivery device 5 of the binding machine body 3A. An air cylinder 63 is connected to the upper part of the swing frame body 62, and a lower side of the connection part of the air cylinder 63 is pivotally supported on the bracket 64, and the lower side swings using this as a fulcrum. A bellows mechanism 65 similar to that of Patent Document 2 including a pair of bellows portions 65A and 65B is provided on the lower end portion of the swing frame 62 and the binding machine main body 3A facing the lower end portion. Although not shown in FIG. 5, the bellows mechanism 65 inserts a zigzag long plastic plate into two metal rods as shown in FIG. The binding machine body 3A is also provided with a mechanism for binding the binding tape to the opening end 4A of the wrapping bag 4, but details thereof are omitted.

前記のように、被包装物が充填された包袋4は、送り機構6の挟持片50により吊り下げられ下部は支持されていないため、被包装物が重い場合は、受渡し装置5から蛇腹機構65へ包袋4を受け渡した後、受渡し装置5が挟持しなくなった場合に、蛇腹機構の摩擦力だけでは包袋4が落下するおそれがある。このため、受渡し装置5から蛇腹機構65へ受け渡すタイミングで、包袋4を他の機構で保持をしなければならないが、包袋4の全面を挟持すると、包袋4の開口端部4Aを蛇腹状に折り畳むことがでず、包袋4が結束できなくなる。そこで、本発明では、結束機3に一点押え機構66を設けている。 As described above, the packaging bag 4 filled with an article to be packaged is suspended by the sandwiching piece 50 of the feeding mechanism 6 and the lower part is not supported. If the delivery device 5 is no longer clamped after the delivery of the packaging bag 4 to 65, the packaging bag 4 may fall with only the frictional force of the bellows mechanism. For this reason, at the timing of delivery from the delivery device 5 to the bellows mechanism 65, the packaging bag 4 must be held by another mechanism. However, when the entire surface of the packaging bag 4 is sandwiched, the opening end 4A of the packaging bag 4 is It cannot be folded into a bellows shape, and the wrapping bag 4 cannot be bound. Therefore, in the present invention, the binding machine 3 is provided with a one-point presser mechanism 66.

一点押え機構66は、図6に示すように、揺動枠体62の揺動を利用して包袋4の中心の一点を押える。この一点押え機構66は、結束機本体3A側にストッパースクリュー66Aを、揺動枠体62側に前記ストッパースクリュー66Aを受ける受け部66Bを設けている。ストッパースクリュー66Aは、結束機本体3Aに取り付けた取付板66Cの中央部に、受け部66B側に突出して取り付けられている。受け部66Bは揺動枠体62の下部枠部分の中央部に、前記ストッパースクリュー66Aと対向する位置に取り付けられている。ストッパースクリュー66Aの先端にウレタン製のストッパー片が取り付けられ摩擦により落下しないようにしている。 As shown in FIG. 6, the one-point pressing mechanism 66 presses one point at the center of the wrapping bag 4 using the swing of the swing frame 62. The one-point pressing mechanism 66 is provided with a receiving portion 66B for receiving the stopper screw 66A on the binding machine body 3A side and receiving the stopper screw 66A on the swing frame body 62 side. The stopper screw 66A is attached to the central portion of the attachment plate 66C attached to the binding machine body 3A so as to protrude toward the receiving portion 66B. The receiving portion 66B is attached to the central portion of the lower frame portion of the swing frame 62 at a position facing the stopper screw 66A. A stopper piece made of urethane is attached to the tip of the stopper screw 66A so as not to fall due to friction.

図5に示すように、送り機構6により被包装物が充填された包袋4が結束機3の中央部に搬送されてくると、シリンダ63が作動して揺動枠体62の下端が閉じ、包袋4の開口端部4Aを蛇腹機構65が挟持する。蛇腹機構65が包袋4の開口端部4Aを挟持すると同時に、一点押え機構66のストッパースクリュー66Aと受け部66Bが包袋4を一点で挟み込む。蛇腹機構65だけでは挟持しきれない包袋4でも落下するおそれが殆んどなくなる。一点押え機構66がしっかりと包袋4を挟み付けた後、送り機構6は結束機3の前から退避して次の包袋4を迎えに行く。 As shown in FIG. 5, when the packaging bag 4 filled with an article to be packaged is conveyed to the central portion of the binding machine 3 by the feeding mechanism 6, the cylinder 63 is activated and the lower end of the swing frame 62 is closed. The bellows mechanism 65 sandwiches the opening end 4A of the sachet 4. At the same time as the bellows mechanism 65 holds the opening end portion 4A of the bag 4, the stopper screw 66A and the receiving portion 66B of the one-point pressing mechanism 66 pinch the bag 4 at one point. There is almost no risk of falling even with the wrapping bag 4 that cannot be clamped by the bellows mechanism 65 alone. After the one-point pressing mechanism 66 firmly clamps the packaging bag 4, the feed mechanism 6 retreats from the front of the binding machine 3 and picks up the next packaging bag 4.

蛇腹機構65の蛇腹部65A,65Bは、駆動装置により収縮して包袋の開口端部4Aに蛇腹状の折り目を付ける。その後、蛇腹状に折り畳まれた開口端部4Aの根元部分を、図示しない結束バンドの絞り機構により、結束バンドで絞って結束する。結束後は搬出コンベア7により排出される。 The bellows portions 65A and 65B of the bellows mechanism 65 are contracted by the driving device to make a bellows-like crease at the opening end portion 4A of the bag. Thereafter, the root portion of the opening end 4A folded in a bellows shape is squeezed and bound by a binding band by a binding band not shown mechanism. After binding, the paper is discharged by the carry-out conveyor 7.

本発明は、袋口をシールした包袋の上部を蛇腹状に折り畳んで、結束テープで結束する結束機を備える包装装置に有用である。   INDUSTRIAL APPLICABILITY The present invention is useful for a packaging apparatus including a bundling machine that folds the upper part of a wrapping bag with a sealed bag mouth into a bellows shape and binds it with a binding tape.
