【発明の属する技術分野】
本発明は、被包装物を収容した袋詰め包装包装体の袋口をひだ重ね状に収束する装置及び、前記収束部を結束材でもって結束するための装置に関する。
【０００２】
【発明が解決しようとする課題】
従来の最も代表的で能率的な袋口結束としては、被包装物を収容するプラスチック製包袋の袋口の両面からそれぞれ櫛歯を押し込んで同袋口に多数の縦ひだを形成すると共に、さらに該縦ひだを寄せ重ね、その寄せ集めたひだ部分をソーセージクリップのごとき結束材で結束する方法があるが、当該方法は、前記櫛歯の袋口への押し込み工程、同櫛歯間隔の収縮工程、同櫛歯の袋口からの退避工程が必要条件であるので、能率面で難点がある。そこで本発明は、手段を小型化及び能率化するのに相応しい方法及び装置を開示するものである。
【０００３】
【その解決手段】
本発明は前記目的を達成するために、被包装物を収容する袋型包装体の袋口を、同袋口に形成する多数のひだを寄せ集めて収束する手段であって、前記袋口を両側から挟持して袋型包装体を運搬する両側一対のメイン回転ベルトと、前記袋口にひだを形成するために前記両メイン回転ベルトの対向面に形成した多数の噛み合せ歯と、前記両メイン回転ベルトを隔てその搬出部上下に配置した２枚の収束受け板と、前記両収束受け板における前記両メイン回転ベルトとの対向部にそれぞれ形成した凹型スリットと、前記両凹型スリット内にじぐざぐ状に送り込まれた袋口を同凹型スリットの奥壁に押し込む作動片と、結束機とにより構成する。
【０００４】
袋口を両側から挟持して袋型包装体を運搬する両側一対のメイン回転ベルト対向面に形成した多数の噛み合せ歯は、その噛み合わせでもって、袋を運搬しながらひだを形成したあと、その搬出部に配置する収束受け板の凹型スリット内にじぐざぐ状に送り込み、作動片でもって同凹型スリットの奥壁に押み収束した袋口を結束機で結束する。この場合収束した袋口を上下２枚の収束受け板で支えるから、袋口は扇形に広がらず結束のミスを防止する。
【０００５】
【発明の実施形態】
図１は両側一対の板フレーム１０に配置した多数のローラ群１１に、２環のエンドレスメイン回転ベルト１２を支持している。これらベルト１２は俗にいうタイミングベルトで、その内側の面には前記ローラ群１１との噛み合わせを行なうための凹凸１３があり、一方同外側対向面には袋口にひだを形成するための噛み合わせ歯１４をそれぞれ形成する。前記ベルトの入り口側から矢印１５のごとく両メイン回転ベルト１２の間に包装体の袋口を差し入れると、原動プーリ１６の回転動力でもって作動するメイン回転ベルト１２によって、図２のごとく包装体２０は吊り下げられ、出口１７に向けて搬送を受ける。それを、方向を変えて眺めると正しく図３の状態で、両側のメイン回転ベルト１２それぞれの上下には、同メイン回転ベルトと同調回転するそれぞれ一対の上部補助ベルト１８及び下部補助ベルト１９を備え、しかもこれら上下補助ベルトは対向面に、前記メイン回転ベルト１２の噛み合わせ歯１４と同じピッチの噛み合わせ歯を備えるので、包装体２０の袋口は、上下３種の噛み合わせ歯で縦長のひだを保ちながら運搬を受ける。
【０００６】
図１に示すようにベルトの出口には、収束受け板２１に形成した凹部スリット２２が対向し、該収束受け板２１には作動片２３が枢支ピン２４を介して回転自在に支持される。袋口の搬送軌道に設置した接触片２５に触れる袋口の抵抗で、前記接触片２５が回転すると、センサー２６から発する信号によって作動片２３は回転する。すなわち図４のごとく、じぐざぐ状のひだを付けた包装体２０の袋口が凹部スリット２２内に進入すると、前記センサーからの信号で起動する第１シリンダ２５が作動片２３を回転させ、包装体袋口を凹部奥壁に押し付けて収束する。なお図５の実施例は上下に所定間隔で２枚の収束受け板２１を備え、シリンダ２５で回転する作動片２３は上下２枚の収束受け板２１に袋口２６のひだを押し込むので、後程理由を説明するが、袋口のひだを細長く保持することができる。
【０００７】
図６実施例のごとく、前記の収束受け板２１をブラケット３０に対し、短ピン３１を介して回転自在に支持すると共に、ブラケット３０を固定する筒形スライダー３２を、機台３３に固定する棒状ガイド３４に支持している。作動片２３が袋口を凹部スリット２２奥に押し込み収束すると、前記ガイド３４に沿って収束受け板２１は、前記袋口を矢印３５のごとく結束点３６まで移動する。この結束点３６には例えば図７のごとき結束機６０を配置する。該結束機は側壁４１を開放して待機するので、収束受け板に支持した袋口は矢印４４のごとくハンマー台４２における窪み４３の対向位置まで送り込まれる。側壁４１が仮想線４１aのごとく閉鎖すると、積層保管する金属性結束材４５の最下部のものは、ハンマー４６の移動衝撃でもって窪み４３に叩き付けられ、図８のごとく包装体２０の収束袋口２６を結束材４５でもって、俗にいうソーセージクリップする。図７でシリンダ４７によって作動するカッター４８は、図８の線４９の部分で袋口を切断する。なお図７の結束機の構成は公知であり、例えばプラスチック製結束材を使用するなど、他に種々の構成品が存在するので、その選択は自由である。
【０００８】
図６における点３６において袋口を結束材で締付た直後、第１シリンダ２５はピン２４を軸に作動片２３を時計方向に開放し、同時に第２シリンダ５１が収束受け板２１を、短ピン３１を軸に逆時計方向に回転する。かかる作用により図９に示すごとく収束受け板２１は結束点３６から離反する。かかる離反量は図６において矢印５２の長さに相当し、円弧軌道で終点５３に達する。そのあとガイド３４に対するスライダー３２のスライド作用及び、第２シリンダー５１のストローク作用で収束受け板２１は矢印５４の軌道を辿って元の定位置に復帰する。つまり図１におけるベルト出口での収束受け板２１の待機位置である。
【０００９】
図６の結束点３６における図７の結束機６０の配置位置は、図５に示すごとく上下２枚の収束受け板２３の中間、仮想線６０で示す部分であり、袋口２６を上下２枚の収束板受け板２３で縦長に保持する結果、結束機６０はトラブル少なく袋口に結束材を巻き付ける。

BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for converging a bag mouth of a bag-packaging package containing a packaged article in a pleated form, and an apparatus for binding the converging part with a binding material.
[0002]
[Problems to be solved by the invention]
As the most typical and efficient bag mouth tying of the past, as well as forming a number of vertical pleats in the bag mouth by pushing comb teeth from both sides of the bag mouth of the plastic wrapping bag that accommodates the package, Further, the vertical folds are brought together and there is a method of binding the gathered folds with a binding material such as a sausage clip. This method includes the step of pushing the comb teeth into the bag mouth and the contraction of the comb teeth intervals. Since the process and the step of retracting the comb teeth from the bag mouth are necessary conditions, there is a problem in terms of efficiency. The present invention thus discloses a method and apparatus suitable for miniaturizing and improving the efficiency of the means.
[0003]
[Solution]
In order to achieve the above-mentioned object, the present invention is a means for gathering and converging a bag mouth of a bag-type package for containing an article to be packaged by gathering a large number of pleats formed in the bag mouth. A pair of main rotating belts on both sides for carrying the bag-type package by sandwiching from both sides, a large number of meshing teeth formed on opposite surfaces of the main rotating belts to form pleats in the bag mouth, Two converging receiving plates disposed above and below the carry-out portion with the rotating belt therebetween, concave slits formed in the confronting portions of the converging receiving plates with the two main rotating belts, It comprises a working piece that pushes the bag mouth fed into the back into the back wall of the concave slit and a binding machine.
[0004]
A large number of meshing teeth formed on the opposing surfaces of the pair of main rotating belts on both sides that carry the bag-type package by holding the bag mouth from both sides are formed into pleats while carrying the bag, The bag mouth is fed into the concave slit of the converging receiving plate arranged in the carry-out portion, and is pushed into the inner wall of the concave slit by the operating piece and bound by the binding machine. In this case, since the converged bag mouth is supported by two upper and lower convergence receiving plates, the bag mouth does not spread in a fan shape and prevents a binding error.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
In FIG. 1, two endless main rotating belts 12 are supported by a large number of roller groups 11 arranged on a pair of plate frames 10 on both sides. These belts 12 are commonly used timing belts, and the inner surface has irregularities 13 for meshing with the roller group 11, while the outer facing surface is used to form pleats on the bag mouth. The meshing teeth 14 are formed respectively. When the bag mouth of the package is inserted between the main rotary belts 12 as indicated by an arrow 15 from the entrance side of the belt, the package is operated as shown in FIG. 2 by the main rotary belt 12 that operates with the rotational power of the driving pulley 16 . 20 is suspended and is transported toward the outlet 17. When viewed from different directions, the pair of upper auxiliary belt 18 and lower auxiliary belt 19 that rotate in synchronization with the main rotating belt are provided above and below each of the main rotating belts 12 on both sides in the state shown in FIG. In addition, since these upper and lower auxiliary belts are provided with meshing teeth having the same pitch as the meshing teeth 14 of the main rotating belt 12 on the opposing surface, the bag mouth of the package 20 is vertically long with three types of meshing teeth on the upper and lower sides. Receive transport while keeping pleats.
[0006]
As shown in FIG. 1, a concave slit 22 formed in the convergence receiving plate 21 faces the belt outlet, and an operating piece 23 is rotatably supported by the convergence receiving plate 21 via a pivot pin 24. . When the contact piece 25 is rotated by the resistance of the bag mouth that touches the contact piece 25 installed on the conveyance path of the bag mouth, the operation piece 23 is rotated by a signal emitted from the sensor 26. That is, as shown in FIG. 4, when the bag mouth of the packaging body 20 with the ruffled pleats enters the recess slit 22, the first cylinder 25 activated by the signal from the sensor rotates the operating piece 23, and the packaging The body bag mouth is pressed against the back wall of the recess to converge. 5 is provided with two convergence receiving plates 21 at predetermined intervals in the vertical direction, and the operating piece 23 rotated by the cylinder 25 pushes the pleats of the bag mouth 26 into the two upper and lower convergence receiving plates 21. The reason will be explained, but the folds of the bag mouth can be held elongated.
[0007]
As shown in FIG. 6, the convergence receiving plate 21 is rotatably supported with respect to the bracket 30 via a short pin 31, and a cylindrical slider 32 for fixing the bracket 30 is fixed to a machine base 33. It is supported by the guide 34. When the operating piece 23 pushes the bag mouth into the recess slit 22 and converges, the convergence receiving plate 21 moves along the guide 34 to the binding point 36 as indicated by the arrow 35. For example, a binding machine 60 as shown in FIG. Since the binding machine opens the side wall 41 and stands by, the bag mouth supported by the convergence receiving plate is fed to the position opposite to the recess 43 in the hammer base 42 as indicated by an arrow 44. When the side wall 41 is closed as indicated by the imaginary line 41a, the lowermost part of the metallic binding material 45 to be stacked and stored is struck against the recess 43 by the movement impact of the hammer 46, and the convergence bag mouth of the package 20 as shown in FIG. 26 is a sausage clip with a binding material 45. The cutter 48 actuated by the cylinder 47 in FIG. 7 cuts the bag mouth at the portion of the line 49 in FIG. Note that the configuration of the binding machine in FIG. 7 is known, and there are various other components such as using a plastic binding material.
[0008]
Immediately after the bag mouth is tightened with the binding material at the point 36 in FIG. 6, the first cylinder 25 opens the operating piece 23 clockwise around the pin 24, and at the same time, the second cylinder 51 shortens the convergence receiving plate 21. It rotates counterclockwise about the pin 31 as an axis. With this action, the convergence receiving plate 21 is separated from the binding point 36 as shown in FIG. The separation amount corresponds to the length of the arrow 52 in FIG. Thereafter, the convergence receiving plate 21 returns to the original fixed position following the path of the arrow 54 by the sliding action of the slider 32 with respect to the guide 34 and the stroke action of the second cylinder 51. That is, it is the standby position of the convergence receiving plate 21 at the belt exit in FIG.
[0009]
The arrangement position of the binding machine 60 in FIG. 7 at the binding point 36 in FIG. 6 is a portion indicated by a virtual line 60 between the upper and lower two convergence receiving plates 23 as shown in FIG. As a result, the binding machine 60 winds the binding material around the bag mouth with less trouble.
