【発明の属する技術分野】
本発明は、袋結束機で商品の収納袋などの袋の首部を結束する際に収納袋の首部を収束を効果的に行なう袋結束機における袋の収束機構に関する。
【０００２】
【従来技術】
商品を入れたポリエチレン等の収納袋の口を閉じるのに、収納袋の首部をプラスチック製のクリップで結束する袋結束機が使用されている。これは、特開平１０ー１６７２３３号公報に示されるように、収納袋の首部が案内路の端部に導入されたときに、送り装置が作動して収納袋の首部を門形のクリップの脚片で挟むことができるように送り込むとともに、上記脚片を上下に重ね、さらに送り込まれたクリップの脚片の先端を結束部（かしめ部）のかしめ装置でかしめて結束するようにしたものである。
【０００３】
なお、送り装置の詳細は特開平１０ー２０３５０９号公報の図５、図６等に、またかしめ装置は特開平１０ー１６７２３２号公報や特願平１１−６７４５２号に示されている。
【０００４】
ところで、上記結束作業においてクリップの脚片間に袋の首部を挟むためには、案内路内に収納袋の首部を挿入し、首部を収束していなければならない。そのため、図１０(a) (b) に示されるように、案内路２０の開口部の一側に袋収束用の押込み部材２１を回動可能に配置し、クリップの送り装置と連動して作動するようにしたものが知られている。これによれば、案内路２０に袋５を挿入した後、クリップの送り装置が作動すると、同時に押込み部材２１が回動し、袋の後部を案内路２０内に押込んで案内路２０の端部で収束するように作動する。したがって、クリップは確実に首部５ａを挟むように送られるから、結束は良好に行なわれる。
【０００５】
【発明が解決しようとする課題】
ところで、上記袋の首部５ａを結束する際、作業員が袋の首部５ａを手際よく案内路に挿入すればよいが、必ずしもそうとは限らない。もしも、首部５ａの一部の挿入が遅れると、それと関係なく押込み部材２１は自動的に回動するから、同図のように、押込み部材２１の先端はむしろ袋の首部５ａを案内路２０の外側に押し出すように作用してしまう。したがって、首部５ａは逆に収束されないことになり、結束不良となってしまう。
【０００６】
このため、作業員の熟練度に関係なく袋を案内路２０内に入れるためには案内路２０を長くすることが考えられる。首部５ａが案内路２０内に入っていれば押込み部材により確実に収束されるからである。袋の首部は案内路２０が長ければ長いほど収束効果は高いのである。したがって、案内路２０は長い方が好ましい。しかし、案内路２０を長くすると、結束機本体２２の幅も広くしなければならず、大型になってしまうという問題がある。このため、案内路２０を長くするには限界がある。
【０００７】
本発明は上記問題点を解消し、大型化することなしに袋の首部を案内路に確実に取り込んで収束することができる袋結束機における袋の収束機構を提供することをその課題とする。
【０００８】
【課題を解決するための手段】
前記課題を解決するため、本発明に係る袋結束機における袋の収束機構は、盤状の結束機本体に門形クリップの送り装置とクリップのかしめ装置とを備え、送り装置とかしめ装置との間に結束機本体の一側に開口する案内路を形成し、該案内路に沿って挿入した袋の首部を案内路の端部で収束した後、上記送り装置からクリップを送って上記首部の周囲に巻き付け、上記クリップをかしめ装置でかしめて結束する袋結束機において、上記案内路の開口部の一側には、袋の首部を案内路の端部側に押し込んで収束する押し込み部材を設け、上記開口部の他側には、一端側が上記案内路を横断するように張り出し、他端側が上記案内路から退避するように配置された袋ガイドを水平方向に回動自在に設け、上記袋を上記案内路の開口部側から挿入したときに上記袋ガイドの上記一端側に上記袋を係合した状態で袋ガイドが回動して上記他端側が上記案内路の上記開口部他側の延長上に移動するようにしたことを特徴とする。
【０００９】
【発明の実施の形態】
図１は本発明に係る袋結束機の概要を示す平面図である。この結束機は従来のものと同じ構成の盤状の結束機本体１に門形クリップの送り装置２とクリップのかしめ装置３とを備え、送り装置２とかしめ装置３との間に結束機本体１の一側に開口する案内路４を形成し、該案内路４に沿って挿入した袋５の首部５を案内路４の端部で収束した後、上記送り装置２からクリップを送って上記首部５の周囲に巻き付け、上記クリップをかしめ装置３でかしめて結束し、図９に示されるようにクリップａで商品の収納袋５の首部５ａを結束するものである。なお、クリップａは図８に示されるように、プラスチックシートにより門形に形成され、両側に脚片６を有し、脚片６には係合穴７が形成されている。全体としてテープ状に連結され、ロール状に巻装されている。
【００１０】
送り装置２は上記クリップａテープの先頭のクリップａの脚片６の係合穴７に係合ピン（図示せず）を係合させてクリップａ１枚分だけかしめ装置３に送った後に、両側の係合ピンを寄せて先頭のクリップａの脚片６を交差させるものである。かしめ装置３は、交差した脚片６の一方から他方にかしめピン（図示せず）を押し込んで上下の脚片６を強くかしめて一体に結合させて首部５ａを結束させるものである。
【００１１】
なお、送り装置２は特開平１０ー２０３５０９号公報等に、かしめ装置３は特開平１０ー１６７２３２号公報や特願平１１−６７４５２号に示されているので、ここでは詳しい説明を省略する。また、送り装置２とかしめ装置３は操作ハンドルの回動操作に連動するように構成されている。
【００１２】
次に、案内路４の開口部４ａの一側には回動軸８が設けられ、この回動軸８には押込み部材９が水平方向に回動自在に設けられている。この押込み部材９はコ字形の板金から形成され（図２参照）、上板１０と下板１１は平面視Ｌ字形に屈曲し、屈曲部の先端縁は押込み部材９の回動時に案内路４の上下を開口部４ａから奥の端部側に移動して案内路４の大きさ（上下の開口面積）を縮小するように移動する。また、板幅は、下板１１の方が上板１０よりもやや長い。これは案内路４内の袋の首部５ａを確実に押込むためである。先端縁の突出長さも、下板１１の方が上板１０よりも長い。これは袋の首部５ａは下側が広がっているので、下板１１で先に下側部分を押込む必要があるからである。したがって、主に下板１１の方で首部５ａを押込むのである。そして、下板１１には、先端縁１２の、回動軸８から遠い外側が突出するように突部１３が形成されている。
【００１３】
なお、押込み部材９は、クリップａの送り装置２と連動するように構成され、送り装置２の作動と同時に上記先端縁１２が案内路４から遠い位置から案内路４の奥の端部に向かって案内路４を上下から挟むように回動する。
【００１４】
上記構成によれば、案内路４に商品等を収納した袋を挿入した後、袋結束機を作動させると、クリップａの送り装置２が作動し、同時に押込み部材９が回動してその先端縁１２で袋の首部５ａを案内路４内に押込み、案内路４の端部で収束させる。
【００１５】
ところで、袋の首部５ａを案内路４に挿入するときに、なんらかの理由で首部５ａの一部の挿入が遅れたときは、図１の実線で示すように、押込み部材９の先端縁１２の突部１３が袋の首部５ａの案内路４から遠い部分に係合して案内路４の開口部４ａの内側に案内するように回動するので、上記首部５ａの一部は案内路４の外側に逃げることがなく、押込み部材９により確実に収束される。
【００１６】
したがって、上記収束機構によれば、案内路４を長くしなくとも袋の首部５ａを案内路４に確実に取り込んで収束することができる。
【００１７】
なお、袋首部５ａを収束した後、かしめ装置３が作動してクリップａによる結束が終了すると、送り装置２が復帰移動するので、押込み部材９も元の初期位置に戻り回動する。
【００１８】
次に、図３は上述したものと基本的構成が同じ袋結束機で、案内路４の開口部４ａの一側には、袋の首部５ａを案内路４の端部側に押し込んで収束する押込み部材９を設け、上記開口部４ａの他側には、袋ガイド１５を水平方向に回動自在に設けたものである。
【００１９】
押込み部材９は図示したように従来のものと同じ構成のものでもよいが、図１に示したものと同じ構成の押込み部材９でもよい。
【００２０】
袋ガイド１５は結束機本体１に設けられた支軸１６に中間を水平方向に回動自在に軸着し、上記袋ガイド１５は図３及び図４に示されるように直状に形成され、一方の側１５ａは細長の板状に、他方の側１５ｂはコ字形に折り曲げ形成された板金から成り、ほぼ中間部が上記支軸１６に軸着されている。また、袋ガイド１５は上記案内路４に対して直交する位置と案内路４と平行になる位置との間で水平方向に回動可能に設けられている。そして、上記袋ガイド１５の上記他端と支軸１６近傍との間には引っ張りバネ１７が取付けられ、この引っ張りバネ１７により袋ガイド１５は常時上記案内路４に対して直交する位置にあるように付勢されている。
【００２１】
袋ガイド１５が案内路４に対して直交する位置にあるときは、袋ガイド１５の板状の一端側が上記案内路４を横断するように張り出し、コ字形の他端側が上記案内路４から退避する状態となる。そして、袋ガイド１５が上記案内路４と平行になる位置では、図５及び図６に示されるように、板状の一端側部分１５ａが案内路４の（袋ガイド１５取付側の）側縁４ａと重なり、コ字形の他端側部分１５ｂが案内路４の側縁４ａの延長上に延びる状態となる。
【００２２】
なお、袋ガイド１５は図７に示されるように、押込み部材９の上板１０と下板１１との間に挟まれる程度の大きさとし、互いに干渉しないようにする。
【００２３】
上記構成によれば、図３に示すように、袋を案内路４の開口部４ａから内部に挿入しようとすると、首部５ａが袋ガイド１５の一端側に係合するので、これをさらに押込んで内部に入れると、押込まれた袋ガイド１５は引っ張りバネ１７のバネ力に抗して回動するので、図５及び図６に示すように、コ字形の他端側部分１５ｂが案内路４の側縁４ａの延長上に延びる状態となる。この状態では、案内路４の上記側縁が延長したのと同じことになるから、袋の首部５ａで案内路４からはみ出した部分があれば、この部分は袋ガイド１５の他端側１５ｂにより案内路４側に案内される。そして、袋結束機が作動すると、前述と同様にクリップａの送り装置２が作動し、同時に押込み部材９が回動してその先端縁１２で袋の首部５ａを案内路４内に押込むから、上記首部５ａは確実に案内路４の端部で収束させる。したがって、上記収束機構によれば、大型化することなしに袋の首部５ａを案内路４に確実に取り込んで収束することができる。
【００２４】
なお、袋首部５ａを収束した後、かしめ装置３が作動してクリップａによる結束が終了して案内路４から袋が排出されると、引っ張りバネ１７により袋ガイド１５は初期に復帰回動して次の結束作業が準備される。押込み部材９も同様に初期位置に戻る。

BACKGROUND OF THE INVENTION
The present invention relates to a bag convergence mechanism in a bag binding machine that effectively converges the neck of a storage bag when binding the neck of a bag such as a product storage bag with a bag binding machine.
[0002]
[Prior art]
A bag binding machine that binds the neck of a storage bag with a plastic clip is used to close the mouth of a storage bag made of polyethylene or the like containing products. As shown in Japanese Patent Application Laid-Open No. 10-167233, when the neck of the storage bag is introduced into the end of the guide path, the feeding device is activated so that the neck of the storage bag is attached to the leg of the portal clip. It is fed so that it can be pinched by a piece, and the above leg pieces are stacked up and down, and the tip of the leg piece of the fed clip is caulked with a caulking device of a bundling part (caulking part) to bind them together. .
[0003]
The details of the feeding device are shown in FIGS. 5 and 6 of JP-A-10-203509, and the caulking device is shown in JP-A-10-167232 and Japanese Patent Application No. 11-67452.
[0004]
By the way, in order to sandwich the neck portion of the bag between the leg pieces of the clip in the bundling operation, the neck portion of the storage bag must be inserted into the guide path and the neck portion must be converged. Therefore, as shown in FIGS. 10 (a) and 10 (b), the pushing member 21 for converging the bag is rotatably arranged on one side of the opening of the guide path 20, and is operated in conjunction with the clip feeding device. What you do is known. According to this, after the bag 5 is inserted into the guide path 20, when the clip feeding device is activated, the pushing member 21 is simultaneously rotated, and the rear portion of the bag is pushed into the guide path 20 to end the end of the guide path 20. Operates to converge. Therefore, since the clip is securely fed so as to sandwich the neck portion 5a, the binding is performed well.
[0005]
[Problems to be solved by the invention]
By the way, when binding the neck portion 5a of the bag, an operator may insert the neck portion 5a of the bag into the guide path, but this is not always the case. If the insertion of a part of the neck portion 5a is delayed, the pushing member 21 is automatically rotated regardless of this, so that the tip of the pushing member 21 rather the bag neck portion 5a passes through the guide path 20 as shown in FIG. It acts to push it outward. Accordingly, the neck portion 5a is not converged, resulting in poor binding.
[0006]
For this reason, it is conceivable to lengthen the guide path 20 in order to put the bag into the guide path 20 regardless of the skill level of the worker. This is because if the neck portion 5a is in the guide path 20, it is reliably converged by the pushing member. The longer the guide path 20 is, the higher the convergence effect of the bag neck is. Accordingly, the guide path 20 is preferably longer. However, if the guide path 20 is lengthened, the width of the binding machine main body 22 must be widened, resulting in a problem that the size becomes large. For this reason, there is a limit to lengthening the guide path 20.
[0007]
An object of the present invention is to solve the above-mentioned problems and to provide a bag converging mechanism in a bag binding machine that can reliably bring the neck of the bag into the guide path and converge without increasing the size.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the bag converging mechanism in the bag binding machine according to the present invention comprises a plate-shaped binding machine body including a portal clip feeding device and a clip caulking device, and the feeding device and the caulking device. A guide path that opens on one side of the binding machine body is formed between the bag and the neck of the bag inserted along the guide path is converged at the end of the guide path. wrapped around, in a bag tying machine for tying by crimping the clip crimping device, to one side of the opening of the guideway, press and inclusive that converges push the neck of the bag on the end side of the guide path only set a member, on the other side of the opening, projecting as one end traverses said guide path, rotatably bag guide the other end side is arranged so as to retract from the guide path in the horizontal direction Install and insert the bag from the opening side of the guideway That the other end the bag guide is rotated in engagement with the bag on the one end side of the bag guide is adapted to move on the extension of the opening the other side of the guide path when the Features.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a plan view showing an outline of a bag binding machine according to the present invention. This binding machine includes a board-like binding machine body 1 having the same configuration as a conventional one, and a portal clip feeding device 2 and a clip caulking device 3, and the binding machine body between the feeding device 2 and the caulking device 3. 1 is formed on one side, the neck 5 of the bag 5 inserted along the guide path 4 is converged at the end of the guide path 4, and then a clip is sent from the feeding device 2 to It is wound around the neck portion 5, the clip is caulked with the caulking device 3, and the neck portion 5a of the product storage bag 5 is bound with the clip a as shown in FIG. As shown in FIG. 8, the clip a is formed in a gate shape with a plastic sheet, has leg pieces 6 on both sides, and an engagement hole 7 is formed in the leg piece 6. The whole is connected in a tape shape and wound in a roll shape.
[ 0010 ]
The feeding device 2 engages an engagement pin (not shown) in the engagement hole 7 of the leg piece 6 of the top clip a of the clip a tape and feeds the clip a by the amount of one clip a to the caulking device 3, then both sides The leg pieces 6 of the leading clip a are crossed by bringing the engagement pins together. The caulking device 3 pushes a caulking pin (not shown) from one of the crossed leg pieces 6 to the other to strongly caulk the upper and lower leg pieces 6 together to bind the neck portion 5a.
[ 0011 ]
The feeding device 2 is disclosed in Japanese Patent Application Laid-Open No. 10-203509 and the like, and the caulking device 3 is disclosed in Japanese Patent Application Laid-Open No. 10-167232 and Japanese Patent Application No. 11-67452, and detailed description thereof is omitted here. Further, the feeding device 2 and the caulking device 3 are configured to be interlocked with the turning operation of the operation handle.
[ 0012 ]
Next, a rotation shaft 8 is provided on one side of the opening 4a of the guide path 4, and a pushing member 9 is provided on the rotation shaft 8 so as to be rotatable in the horizontal direction. The pushing member 9 is formed of a U-shaped sheet metal (see FIG. 2), the upper plate 10 and the lower plate 11 are bent in an L shape in plan view, and the leading edge of the bent portion is the guide path 4 when the pushing member 9 is rotated. Is moved from the opening 4a to the back end side so as to reduce the size of the guide path 4 (upper and lower opening areas). The plate width of the lower plate 11 is slightly longer than that of the upper plate 10. This is because the neck portion 5a of the bag in the guide path 4 is surely pushed. The protruding length of the leading edge is also longer on the lower plate 11 than on the upper plate 10. This is because the lower part of the neck 5a of the bag needs to be pushed in first with the lower plate 11. Therefore, the neck portion 5a is pushed in mainly by the lower plate 11. A protrusion 13 is formed on the lower plate 11 so that the outer side of the tip edge 12 far from the rotation shaft 8 protrudes.
[ 0013 ]
The pushing member 9 is configured to be interlocked with the feeding device 2 of the clip a, and simultaneously with the operation of the feeding device 2, the distal end edge 12 moves from a position far from the guide path 4 toward the back end of the guide path 4. The guide path 4 is rotated so as to be sandwiched from above and below.
[ 0014 ]
According to the above configuration, when the bag binding machine is operated after inserting a bag containing goods or the like into the guide path 4, the feeding device 2 of the clip a is operated, and at the same time, the pushing member 9 is rotated to move the tip thereof. The bag neck 5 a is pushed into the guide path 4 at the edge 12 and converged at the end of the guide path 4.
[ 0015 ]
By the way, when the insertion of a part of the neck portion 5a is delayed for some reason when the neck portion 5a of the bag is inserted into the guide passage 4, as shown by the solid line in FIG. Since the part 13 engages with a portion of the bag neck 5a far from the guide path 4 and rotates to guide the inside of the opening 4a of the guide path 4, a part of the neck 5a is located outside the guide path 4. It is surely converged by the pushing member 9 without escaping.
[ 0016 ]
Therefore, according to the convergence mechanism, the bag neck 5a can be reliably taken into the guide path 4 and converged without lengthening the guide path 4.
[ 0017 ]
After the bag neck 5a is converged, when the caulking device 3 is actuated and the bundling by the clip a is completed, the feeding device 2 moves back, so that the pushing member 9 also returns to the original initial position and rotates.
[ 0018 ]
Next, FIG. 3 shows a bag binding machine having the same basic configuration as that described above. The bag neck 5a is pushed into the side of the opening 4a of the guide path 4 to the end side of the guide path 4 and converges. A pushing member 9 is provided, and a bag guide 15 is provided on the other side of the opening 4a so as to be rotatable in the horizontal direction.
[ 0019 ]
As shown in the drawing, the pushing member 9 may have the same configuration as the conventional one, or the pushing member 9 having the same configuration as that shown in FIG.
[ 0020 ]
The bag guide 15 is pivotally attached to a support shaft 16 provided in the binding machine main body 1 so that the middle is rotatable in the horizontal direction, and the bag guide 15 is formed in a straight shape as shown in FIGS. One side 15a is formed of a sheet metal that is formed into an elongated plate shape, and the other side 15b is formed in a U-shape. A substantially intermediate portion is pivotally attached to the support shaft 16. Further, the bag guide 15 is provided so as to be rotatable in a horizontal direction between a position orthogonal to the guide path 4 and a position parallel to the guide path 4. A tension spring 17 is attached between the other end of the bag guide 15 and the vicinity of the support shaft 16 so that the bag guide 15 is always in a position orthogonal to the guide path 4 by the tension spring 17. Is being energized.
[ 0021 ]
When the bag guide 15 is in a position orthogonal to the guide path 4, one end of the bag guide 15 projects so as to cross the guide path 4, and the other end of the U-shape is retracted from the guide path 4. It becomes a state to do. At the position where the bag guide 15 is parallel to the guide path 4, as shown in FIGS. 5 and 6, the plate-like one end side portion 15a is the side edge of the guide path 4 (on the bag guide 15 mounting side). 4a overlaps with the other end portion 15b of the U-shape and extends on the extension of the side edge 4a of the guide path 4.
[ 0022 ]
As shown in FIG. 7, the bag guide 15 is sized so as to be sandwiched between the upper plate 10 and the lower plate 11 of the pushing member 9 so as not to interfere with each other.
[ 0023 ]
According to the above configuration, as shown in FIG. 3, when the bag is to be inserted into the inside from the opening 4 a of the guide path 4, the neck portion 5 a engages with one end side of the bag guide 15. When inserted, the pushed bag guide 15 rotates against the spring force of the tension spring 17, so that the U-shaped other end portion 15 b of the guide path 4 is formed as shown in FIGS. 5 and 6. It will be in the state extended on extension of the side edge 4a. In this state, the side edge of the guide path 4 is the same as that extended, so if there is a portion that protrudes from the guide path 4 at the neck portion 5a of the bag, this portion is caused by the other end side 15b of the bag guide 15. Guided to guideway 4 side. When the bag binding machine is operated, the feeding device 2 for the clip a is operated as described above, and at the same time, the pushing member 9 is rotated to push the bag neck 5a into the guide path 4 at the leading edge 12 thereof. The neck portion 5a is reliably converged at the end of the guide path 4. Therefore, according to the said convergence mechanism, the neck part 5a of a bag can be reliably taken in and converged on the guide path 4 without enlarging.
[ 0024 ]
After the bag neck 5a is converged, when the caulking device 3 is actuated to finish the binding by the clip a and the bag is discharged from the guide path 4, the bag guide 15 is rotated back to the initial state by the tension spring 17. The next bundling work is prepared. The pushing member 9 similarly returns to the initial position.
