【発明の属する技術分野】
この発明は、食品等の包装用樹脂袋を結束する袋結束機の起動制御装置に関するものであり、特に、結束具の有無を判断して起動停止制御を行う起動制御装置に関するものである。
【0002】
【従来の技術】
例えば、青果物やパン等の商品を収納した樹脂製袋の開口部を迅速確実に結束するために、本願出願人は樹脂板の結束具を袋の収束部へ自動的に締着する袋結束機(実願平5−49916号、特願平8−267542号)を提案している。
【0003】
上記の袋結束機は、フレーム内に結束具の送り装置と結束装置とを内蔵し、フレームの一側面から中央部へ向けて形成した袋挿入用の案内溝へ袋の結束部位を挿入すると、トリガスイッチによりモータが起動する。そして、モータが主ギヤ及びカム機構を介して結束具送り装置のキャリヤを待機位置から前方へ駆動し、門形の結束具を袋の収束部位に外嵌した後に、結束具の両脚部をたすき掛けする(実願平5−49916号)か、または、両脚部を交差させてパンチング及びかしめによって結合する(特願平8−267542号)。また、袋の結束具締結部位の上の余剰部分は、結束装置と連動するカッター装置によって切断される。
【0004】
【発明が解決しようとする課題】
従来の袋結束機は、案内溝へ袋の結束部位を挿入すると自動的に起動して、結束具の送りと締結、及び袋の切断とからなる1サイクルの動作を行うが、送り装置に装填されている連結形結束具を使いきった後のサイクルにおいては、袋は結束されず、カッター装置により袋の上部が切断されてしまう。
【0005】
このとき、作業者は連結形結束具を使いきったことが分かり、結束機に結束具を補充して作業を再開することになるが、結束具が装着されないで上部を切断された袋は、結束作業時に把持する部分がなくなっているので結束することができない。よって、その袋の内容物を新たな袋に移し替える手間がかかったり、内容物が流動体の場合は袋からこぼれ落ちて無駄になる等の問題がある。
【0006】
そこで、結束具の残量がゼロになった際に袋が切断されないようにして取扱い性を向上するために解決すべき技術的課題が生じてくるのであり、本発明は上記課題を解決することを目的とする。
【0007】
【課題を解決するための手段】
合成樹脂製の門形平板である連結形結束具を袋の収束部位へ外嵌する結束具送り装置と、前記結束具の両脚を閉鎖方向へ押圧して交差させ、両脚部をたすき掛け、または圧着する結束装置と、袋の結束部位の上部余剰部分を切断するカッター装置を備え、トリガスイッチのトリガ信号にて1サイクルの結束動作を実行する袋結束機であって、連結形結束具の結束具通路に結束具の有無を検出するセンサを設け、該センサにより連結形結束具の残量がゼロになったことを検出したとき、該袋結束機の起動を停止させるように構成した袋結束機の起動制御装置において、
上記センサがオフ状態で上記袋結束機による連結形結束具の結束作業に伴い、該連結形結束具を消費して、該連結形結束具の最後尾の結束具が前記センサの位置を通過し、袋結束機の結束具通路内の連結形結束具の残量が所定数になったときから前記センサがオンして連結形結束具の結束サイクル数のカウントを開始し、該カウント数が上記所定数に達し、上記結束具通路内の連結形結束具の残量がゼロになったとき袋結束機の起動を禁止するように構成した袋結束機の起動制御装置を提供する。
【0008】
【発明の実施の形態】
以下、この発明の実施の一形態を図に従って説明する。図1は袋結束機1を示し、向かって右側は結束具マガジン部2となっており、ベルト状に連結された結束具のロールが収容される。結束具マガジン部2から左へ突出するテーブル部3には、前面左右中間部から奥に向かった後に左へ屈折する平面L字形の案内溝4が形成されている。テーブル部3内には案内溝4の右に結束具の送り装置5が内蔵され、左には結束装置6が内蔵されている。
【0009】
結束装置6の後方にはカッター装置7が配置され、テーブル部3の上面に回動自在に枢着したアーム部7aを手前側へ回動して、前部の案内溝7bをテーブル部3の案内溝4と合致させれば、結束動作と連動してアーム部7a内を前後にスライドするカッター刃(図示せず)が結束した袋の上部余剰部分をカットする。
【0010】
送り装置5と結束装置6とカッター装置7は、減速ギヤ機構及びカム及びリンク機構を介して一台のモータ(図示せず)により駆動される。案内溝4の左側にはトリガレバー8が枢着されていて、トリガレバー8の先端部は右側に延びて案内溝4を横断しており、袋の開口部を収束して案内溝4の奥へ挿入すると、トリガレバー8が袋に押されて回動し、テーブル部3内のトリガスイッチ(図示せず)がオンしてモータが起動する。
【0011】
図2に示すように、結束具9はほぼ門形の樹脂製平板であり、左右の脚部10の内側基部には内歯ギヤ状に抜け止め爪部11が設けられている。両脚部10には、後述する送り装置5のアームのピンを係合させるための穴12が形成され、先端部位には外側面から内側前方へ向かう溝13が設けられてフック部14が形成されている。そして、多数の結束具9をベルト状に一列に連結した一体成形品をロール状に巻回したものを袋結束機1の結束具マガジン部2に装填する。
【0012】
図3は送り装置5と結束装置6の配置を示し、同図に示すように、袋結束機1のベースに設けたキャリヤガイド15にキャリヤ16が前後スライド自在に係合し、キャリヤ16が結束装置6に向かって前進しつつ結束具9を袋に外嵌し、袋に装着された結束具9を結束装置6が締結する。
【0013】
送り装置5のキャリヤ16上に前後スライド自在に装着された結束具ガイド17は、上ケースと下ケースとからなり、上ケースと下ケースとの間隙は中高(断面への字形)の結束具通路となっている。結束具ガイド17の前部(図において左)は結束具9と相似形の結束具テーブル18が形成され、結束具通路を通じて前方へ供給される結束具9が結束具テーブル18上に露出する。
【0014】
結束具テーブル18の後方には左右一対のC形結束アーム19が同軸に枢着され、結束アーム19の後方の前後スライド自在なアームシフタ20と結束アーム19とがリンク21によって連結されている。結束アーム19の先端部には垂直方向のピン22が突設され、ピン22は図2に示した結束具9の両側の穴12に係合する。また、アームシフタ20に設けた溝20aにはキャリヤ16に固定したピン16aが係合している。
【0015】
キャリヤ16の下方には大径の主ギヤ23が配置され、主ギヤ23の外縁近傍に設けたクランクローラ24がキャリヤ16の後部に形成したカム溝16bに係合し、主ギヤ23は複数段の減速ギヤ(図示せず)を介してモータに結合されている。
【0016】
図示は省略するが、キャリヤ16と結束具ガイド17とには揺動する爪を利用した公知の送り爪機構(図示せず)が介装され、結束具ガイド17に枢着した送り爪がキャリヤ16に係合し、結束具ガイド17はキャリヤ16に押されてキャリヤ16とともに前進する。そして、一定距離進んだときに結束具ガイド17がストッパに当接して停止するとともに送り爪がキャリヤ16から離脱し、キャリヤ16並びにアームシフタ20が更に前進し、左右一対の結束アーム19がアームシフタ20に押されて閉鎖方向へ回動する。
【0017】
主ギヤ23の軸には、切欠き25aを設けた円板25を嵌着し、フレーム(図示せず)に固定したフォトインタラプタ26の発光部と受光部とが円板25の外縁部を挟んで上下で対向している。フォトインタラプタ26はモータ制御部(図示せず)に接続され、モータ制御部がフォトインタラプタ26の出力に基づいてキャリヤ16の停止位置を制御する。
【0018】
図4に示すように、袋結束機1の結束具マガジン部2から主ギヤ23並びにキャリヤ16の上方を通って結束具ガイド17の結束具導入口17aへ至る結束具経路には、結束具9の有無を検出するフォトインタラプタ27を設けてモータ制御部に接続している。フォトインタラプタ27の発光部と受光部は、結束具9の側縁部の上下で対峙していて、発光部と受光部との間に結束具が在る場合は受光部の出力はオフし、結束具が無い場合はオン信号を出力する。
【0019】
フォトインタラプタ27は、結束具ガイド17の結束具テーブル18上の先頭の結束具9aから8番目の結束具9hの脚部の位置にあり、結束具が順次前方へ送られて残量が7個になったときに、発光部と受光部との間の結束具が無くなり、オン信号が継続することになる。
【0020】
モータ制御部は、フォトインタラプタ27のオン信号が一定時間以上継続したときにカウンタにダウンカウントデータ=7をセットする。以後、トリガスイッチのトリガ信号が入力される都度、カウントデータから1を減算してカウントデータ=0となった時点で、モータの起動を禁止する。
【0021】
次に、袋結束機1の動作を説明する。青果物等を投入した樹脂袋の上端開口部を手で束ねつつ図1に示す案内溝4へ挿入すると、トリガレバー8が袋に押されて回動し、トリガレバー8がテーブル部3内のトリガスイッチをオンしてモータが起動する。
【0022】
モータによって主ギヤ23が回転すると、図3に示すクランクローラ24に押されてキャリヤ16並びに結束具ガイド17が前方に移動する。連結形結束具9の先頭の結束具は、結束アーム19のピン22に係合しているので、結束具ガイド17とともに前進して袋の収束部位に外嵌される。なお、このとき、図示は省略するが、従来形の袋結束機と同様に結束具ガイド17の上面に装着したカッターが先頭の結束具と次列の結束具との連結部を切断する。
【0023】
そして、結束具ガイド17の結束具テーブル18上の結束具が結束装置6の前部内に入り込んだ位置で、結束具ガイド17の送り爪がキャリヤ16から外れて結束具ガイド17は停止し、キャリヤ16並びにアームシフタ20は更に前進する。これにより、結束具ガイド17に枢着されている左右一対の結束アーム19が閉鎖方向へ回動して先頭の結束具9の両脚部を交差させ、図5に示すように、結束具9は漏斗状に弾性変形する。このとき、結束装置6のプレスピンは結束具9の両脚部10の直下に位置している。
【0024】
結束装置6の構成は公知であるので詳細な説明は省略するが、パンチを立設したプレートと、ダイであるピン穴を設けた上方のダイプレートとが結束具9の両脚部10を上下から挟圧して両脚部の交差部にダボを成形し、かしめピンを設けたかしめプレートがピン穴の上方からダボをかしめる。
【0025】
図6(a)はパンチとダイにより成形されたダボDの形状を示し、同図(b)はかしめピンによりダボDにかしめ加工Cを行った最終形状を示す。また、図7は袋Bに結束具9が締着された状態を示す。
【0026】
そして、結束装置6の上下のプレートが開いて待機位置に復帰し、キャリア16が一定距離後退した後に結束具ガイド17のガイド送り爪がキャリア15に係合して結束具ガイド17がキャリア16と一体に後退し、主ギヤ23と同軸の円板25の切欠き25aが待機位置検出用フォトインタラプタ26の発光部と受光部との間に達すると、フォトインタラプタ26のオン信号によって、モータ制御部がモータの制動を開始して減速行程に入る。そして、切欠き25aがフォトインタラプタ26の発光部と受光部との間から出てフォトインタラプタ26のオン信号がオフした時点でモータに電磁ブレーキをかけて、図3に示す待機位置で停止する。
【0027】
結束作業に伴い連結形結束具を消費して、連結形結束具9の最後尾の結束具がフォトインタラプタ27の位置を通過し、結束具の残量が7個になったときから、モータ制御部は結束サイクルのカウントを開始する。そして、7サイクルをカウントしたとき、即ち、結束具9の残量がゼロになったときに、モータの起動を禁止する制御に入る。したがって、作業者が袋を袋結束機1の案内溝4に挿入してトリガスイッチがオンしても袋結束機1は起動せず、結束具を使い切ったことが分かり、且つ、把持している袋が切断されることがない。
【0028】
そして、作業者が連結形結束具を結束具マガジン部2に装填し、連結形結束具の先頭部を結束具ガイド17を通じて結束具テーブル18まで挿入すれば、先頭から8番目の結束具9hによりフォトインタラプタ27の出力がオフして起動禁止状態が解除され、結束作業の再開が可能になる。
【0029】
尚、本発明は上記の実施例に限定するものではなく、本発明の技術的範囲内において種々の改変ができ、本発明がそれらの改変されたものに及ぶことは当然である。
【0030】
【発明の効果】
以上説明したように、本発明の袋結束機の起動制御装置は、結束作業に伴い結束具の残量が所定数(例えば、7個)になったときから、モータ制御部は結束サイクルのカウントを開始し、7サイクルをカウントしたとき、即ち、結束具の残量がゼロになったときに、モータ起動を禁止する制御に入る。従って、作業者が袋を袋結束機の案内溝に挿入してトリガスイッチがオンしても袋結束機は起動せず、結束具を使い切ったことが分かる。
そして、作業者が連結形結束具を結束具マガジン部に装填し、連結形結束具の先頭部を結束具ガイドを通じて結束具テーブルまで挿入すれば、先頭から8番目(前記所定数に1を加えた数)の結束具によってフォトセンサの出力がオフして起動禁止状態が解除され、結束作業の再開が可能になる。
又、本発明の袋結束機の起動制御装置は、袋結束機に装填してある連結形結束具が尽きたときは、トリガスイッチをオンしても起動しないので従来の袋結束機とは異なり、カッター装置により、袋の上部が切断されることがない。したがって、袋や商品が無駄になることがなく、取扱い性が向上するとともに作業能率の低下を防止できる。

The above-described bag tying machine incorporates a tying device feeding device and a tying device in the frame, and inserts the tying portion of the bag into a bag insertion guide groove formed from one side of the frame toward the center, The motor is started by the trigger switch. Then, the motor drives the carrier of the tying device feeding device forward from the standby position via the main gear and the cam mechanism, and fits the double tying device outside the converging portion of the bag, and then taps both legs of the tying device. Hanging (Japanese Utility Model Application No. 5-49916), or connecting both legs by punching and caulking (Japanese Patent Application No. 8-267542). In addition, a surplus portion of the bag above the binding part fastening portion is cut by a cutter device that works in conjunction with the binding device.
[0004]
[Problems to be solved by the invention]
The conventional bag binding machine is automatically activated when the binding portion of the bag is inserted into the guide groove, and performs a one-cycle operation including feeding and fastening of the binding device and cutting of the bag. In the cycle after the connected tying tool is used up, the bag is not tied and the upper part of the bag is cut by the cutter device.
[0005]
At this time, the operator finds out that the connection-type tying tool has been used up, and replenishes the tying tool with the tying tool and resumes the work.However, the bag whose upper part is cut without the tying tool is Since there is no portion to be gripped during the binding operation, the binding cannot be performed. Therefore, there is a problem that it takes time to transfer the contents of the bag to a new bag, and when the contents are a fluid, they fall off the bag and become wasteful.
[0006]
Therefore, when the remaining amount of the tying tool becomes zero, a technical problem to be solved arises in order to prevent the bag from being cut and improve the handleability, and the present invention solves the above problem. With the goal.
[0007]
[Means for Solving the Problems]

Then, a roll of an integrally formed product in which a number of binding tools 9 are connected in a line in a belt shape is loaded into the binding tool magazine 2 of the bag binding machine 1.
[0012]
FIG. 3 shows the arrangement of the feeding device 5 and the binding device 6, and as shown in FIG. 3, the carrier 16 is slidably engaged with the carrier guide 15 provided on the base of the bag binding device 1, and the carrier 16 is bound. The binding device 9 is fitted onto the bag while moving forward toward the device 6, and the binding device 6 fastens the binding device 9 attached to the bag.
[0013]
A tying guide 17 slidably mounted on the carrier 16 of the feeding device 5 is composed of an upper case and a lower case, and a gap between the upper case and the lower case has a middle-height (letter shape in cross section) tying member passage. It has become. A binding device table 18 similar in shape to the binding device 9 is formed at the front part (left side in the figure) of the binding device guide 17, and the binding device 9 supplied forward through the binding device passage is exposed on the binding device table 18.
[0014]
A pair of right and left C-shaped binding arms 19 are coaxially pivoted behind the binding tool table 18, and an arm shifter 20 slidable back and forth behind the binding arm 19 and a binding arm 19 are connected by a link 21. A vertical pin 22 protrudes from the distal end of the binding arm 19 and engages with the holes 12 on both sides of the binding tool 9 shown in FIG. A pin 16 a fixed to the carrier 16 is engaged with a groove 20 a provided in the arm shifter 20.
[0015]

And are facing up and down. The photo interrupter 26 is connected to a motor control unit (not shown), and the motor control unit controls the stop position of the carrier 16 based on the output of the photo interrupter 26.
[0018]
As shown in FIG. 4, the tying tool 9 extends from the tying tool magazine 2 of the bag tying machine 1 through the main gear 23 and the carrier 16 to the tying tool introduction port 17a of the tying tool guide 17. And a photo interrupter 27 for detecting the presence or absence of the motor is provided and connected to the motor control unit. The light emitting portion and the light receiving portion of the photo interrupter 27 face each other above and below the side edge of the binding device 9, and when there is a binding device between the light emitting portion and the light receiving portion, the output of the light receiving portion is turned off. If there is no binding device, an ON signal is output.
[0019]
The photo interrupter 27 is located at the position of the legs of the first tie 9a to the eighth tie 9h on the tie table 18 of the tie guide 17, and the tie is sequentially sent forward so that the remaining amount is seven. When, the tying member between the light emitting unit and the light receiving unit disappears, and the ON signal continues.
[0020]
The motor control unit sets down count data = 7 in the counter when the ON signal of the photo interrupter 27 continues for a certain period of time or more. Thereafter, every time the trigger signal of the trigger switch is input, the motor is inhibited from starting when the count data becomes 0 by subtracting 1 from the count data.
[0021]
Next, the operation of the bag binding machine 1 will be described. When the upper end opening of the resin bag into which fruits and vegetables are put is inserted into the guide groove 4 shown in FIG. 1 while being bundled by hand, the trigger lever 8 is pushed by the bag and pivots, and the trigger lever 8 is turned into the trigger in the table unit 3. Turn on the switch to start the motor.
[0022]
When the main gear 23 is rotated by the motor, the carrier 16 and the binder guide 17 are moved forward by being pushed by the crank roller 24 shown in FIG. Since the leading tying member of the connecting tying member 9 is engaged with the pin 22 of the tying arm 19, the leading tying member advances with the tying member guide 17 and is fitted to the converging portion of the bag. At this time, though not shown, a cutter mounted on the upper surface of the tying tool guide 17 cuts the connecting part between the first tying tool and the next tying tool as in the conventional bag tying machine.
[0023]
Then, at a position where the tying tool on the tying tool table 18 of the tying tool guide 17 has entered the front portion of the tying device 6, the feeding claw of the tying tool guide 17 is disengaged from the carrier 16 and the tying tool guide 17 stops, and the carrier 16 and the arm shifter 20 are further advanced. As a result, the pair of left and right binding arms 19 pivotally attached to the binding device guide 17 rotate in the closing direction to cross both legs of the leading binding device 9, and as shown in FIG. It elastically deforms into a funnel shape. At this time, the press pins of the binding device 6 are located immediately below both the legs 10 of the binding device 9.
[0024]
Since the configuration of the binding device 6 is publicly known, the detailed description is omitted. However, the plate on which the punch is erected and the upper die plate provided with the pin holes, which are dies, move the two legs 10 of the binding device 9 from above and below. A dowel is formed at the intersection of both legs by pinching, and a caulking pin is provided. A caulking plate caulks the dowel from above the pin hole.
[0025]
FIG. 6A shows the shape of a dowel D formed by a punch and a die, and FIG. 6B shows the final shape of the dowel D which has been caulked C by a caulking pin. FIG. 7 shows a state in which the binding device 9 is fastened to the bag B.
[0026]
Then, the upper and lower plates of the binding device 6 open and return to the standby position, and after the carrier 16 has retreated a predetermined distance, the guide feeding claws of the binding device guide 17 engage with the carrier 15 so that the binding device guide 17 is connected to the carrier 16. When the notch 25a of the disk 25 coaxial with the main gear 23 reaches between the light emitting portion and the light receiving portion of the photo interrupter 26 for standby position detection, the motor control portion is turned on by the ON signal of the photo interrupter 26. Starts braking of the motor and enters a deceleration stroke. Then, when the notch 25a comes out from between the light emitting portion and the light receiving portion of the photo interrupter 26 and the ON signal of the photo interrupter 26 is turned off, the electromagnetic brake is applied to the motor and stops at the standby position shown in FIG.
[0027]
The connecting type tie is consumed by the tying operation, and the last tie of the connecting type tie 9 passes through the position of the photo interrupter 27, and the motor control is started when the remaining number of the tie is seven. The unit starts counting unity cycles. Then, when seven cycles have been counted, that is, when the remaining amount of the tying member 9 has become zero, the control starts to prohibit the start of the motor. Therefore, even if the worker inserts the bag into the guide groove 4 of the bag binding machine 1 and the trigger switch is turned on, the bag binding machine 1 does not start, and it is understood that the binding tool has been used up and the user holds the bag. The bag is not cut.
[0028]
Then, when the worker loads the connecting type tying tool into the tying tool magazine part 2 and inserts the leading part of the connecting type tying tool to the tying tool table 18 through the tying tool guide 17, the eighth tying tool 9h from the top can be used. The output of the photointerrupter 27 is turned off, the activation prohibition state is released, and the binding operation can be resumed.
[0029]
It should be noted that the present invention is not limited to the embodiments described above, and various modifications can be made within the technical scope of the present invention, and the present invention naturally extends to those modifications.
[0030]
【The invention's effect】
As described above, the start-up control device of the bag binding machine according to the present invention starts counting the number of binding cycles from the time when the remaining number of the binding tools reaches a predetermined number (for example, 7) due to the binding operation. Is started, and when seven cycles have been counted, that is, when the remaining amount of the tying member has become zero, the control for prohibiting the start of the motor is started. Therefore, even if the worker inserts the bag into the guide groove of the bag binding machine and turns on the trigger switch, the bag binding machine does not start, and it can be understood that the binding device has been used up.
Then, if the operator loads the connecting type tying tool into the tying tool magazine part and inserts the leading part of the connecting type tying tool through the tying tool guide to the tying tool table, the eighth from the top (1 is added to the predetermined number). The output of the photo sensor is turned off by the tying tool, and the start prohibition state is released, so that the tying work can be resumed.
Further, the start-up control device of the bag binding machine according to the present invention is different from the conventional bag binding machine because when the connected type binding device loaded in the bag binding machine is exhausted, it does not start even if the trigger switch is turned on. The upper part of the bag is not cut by the cutter device. Therefore, the bag and the product are not wasted, the handleability is improved, and a decrease in work efficiency can be prevented.
