Description

【0001】
【発明の属する技術分野】
本発明は包装機に関し、より詳しくは包装機における縦シールの制御装置に関する。
【0002】
【従来の技術】
熱可塑性の帯状包材をフォマーによって筒状に曲成しつつ充填シリンダの周面に沿わせて移送し、この間に重ね合わせた縦の縁同士を縦シールヒータによりシールするとともに、充填シリンダの下方に配設した横シールヒータにより袋の天の部分と次の袋の地の部分を同時にシールしてゆくようにした包装機、つまり縦型ピロー包装機と呼ばれる包装機には、縦の縁同士を融着する手段としてベルト式の縦シール機構が使用されていて、内容物の充填と包装とを連続的に行うように構成されている。
【0003】
この種の包装機は、支障の生じない限り包材の送りを止めることはないが、包装機からの排出要求信号によって計量機から充填すべき品物が供給されてくるような、包装機主・計量機従のシステムを取るものにおいては、何らかの原因によって品物が供給されてこないような場合、包材の搬送を一時停止させてヒータベルトを包材から離間させるようにしているが、つぎのサイクルにおいてもなお品物が供給されてこないような場合には、ヒーターベルトが一旦包材の縦の縁に接触してつぎの包装に備えて同じ部分を繰返し加熱してしまうため、この部分が溶損して不良の袋を作り出してしまうといった不都合が生じる。
【0004】
一方、このような問題に対して、包材の送りとヒーターベルトを同時に作動させるようにした場合には、送り始めの包材に対する縦のシールが十分に行えないため、横シールしたあとで袋が破損して充填した品物を周辺に飛散させてしまうといった不都合が発生する。
【0005】
【発明が解決しようとする課題】
本発明はこのような問題に鑑みてなされたもので、その目的とするところは、品物が供給されてきてからの再作動時においても不良な包装物を作り出すことのない新たな包装機を提供することにある。
【0006】
【課題を解決するための手段】
すなわち、本発明はかかる課題を達成するために、熱可塑性の帯状包材を筒状に曲成し、重ね合わせた移送方向の縁に縦シールを施しつつ移送して横シールする形式の包装機において計量機への排出要求信号出力時に前記帯状包材をシールできる時間だけ縦シール手段を作動させるとともに、上記計量機からの排出完了信号を待って包材移送手段と横シール手段を作動させるように制御する制御手段を設けるようにしたものである。
【0007】
【作用】
このように構成したことにより、計量機への最初の排出要求信号を出す際に必要な時間包材に縦シールを行わせるとともに、プルダウン機構や横シール機構の作動は計量機からの排出完了信号を待ってから行わすことにより、品物の供給再開当初からシールの確実な袋を成形することができるようにする。
【0008】
【発明の実施の形態】
そこで以下に本発明の実施例について説明する。
図面はいずれも本発明の一実施例を示したものである。
【0009】
多数の計量ヘッドを備えた計量機1の下方には、計量されて放出された品物を受けるホッパ2が配設され、されにこの下方には、包材fを筒状に曲成するフォーマ3と、曲成した包材fを横シール機構7のもとへ移送するプルダウン機構5と、包材fの縦の合わせ目に縦のシールを施す縦シール機構6が配設されている。
【0010】
図2は、本出願人が特開平6−239318号公報に開示した縦シール機構について示したもので、プルダウンベルト51とともに充填シリンダ4の周囲に配設したこの縦シール機構6は、支持ピン61を支点として揺動するスイングアーム62により充填シリンダ4の交換の際に縦シールユニット63を充填シリンダ4から離間できるように構成され、さらに、スイングアーム62には、縦シールベルト66を充填シリンダ4の径に応じた位置に位置決めするサイズ別変更モータ64と、装置が停止した際に包材fの面から縦シールベルト66の押圧を解除させるべく電磁弁65の操作によって動作するベルト接離用シリンダ67が配設されている。
【0011】
なお、図中符号68はシール位置変更用のつまみ、69は包材fが接触する縦シールベルト66の角度を変えるスリーブをそれぞれ示している。
【0012】
再び図1に戻って、図中符号10は、包装機自体もしくは包装システム全体を制御するホストコンピュータの一部をなす制御回路で、この制御回路10は、図示しない操作スイッチを押圧することによって計量機1に排出要求信号を出力する排出要求信号出力手段11と、計量機1からの排出完了信号を受けてタイマ13に信号を出力する排出完了信号入力手段12と、排出完了信号を受けてから機械的な遅らせ時間T1(後述)の経過後に、プルダウン機構5の駆動モータ52と横シール機構7のアーム駆動モータ72に動作信号を出力するタイマ13と、操作スイッチの押圧により、機械的な遅らせ時間T1から要縦シール時間T2(後述)を減算して電磁弁作動信号出力手段15にT1−T2の信号を出力する演算手段14と、はじめは演算手段14からの出力信号により作動信号を出力し、つぎからはタイマ13からの信号を待って電磁弁65に作動信号を出力する電磁弁作動信号出力手段15と、包材fの種類別要縦シール時間T2を演算手段14に入力する包材情報入力手段16とによって構成されている。
【0013】
なお、上記した機械的な遅らせ時間T1とは、図5に示したように、計量機1から排出された品物が噛み合いポイントに達したときに、横シール機構7のジョー71も原点位置0から噛合いポイントに達するように、また包材fの搬送もこの時点から始まるように、横シール機構7とプルダウン機構5の動作に遅れを生じさせるようにした時間を云い、また、要縦シール時間T2とは、包材fの種類に応じて縦シールベルト66のプーリ間距離全体にわたって縦のシールを確実に行わせるための時間を云う。
【0014】
つぎに、このように構成された包装機の包装動作を図3に示した動作タイミングをもとに説明する。
【0015】
予め包材fの種類に応じた要縦シール時間T2が包材情報入力手段16より演算手段14に入力された状態のもとで操作スイッチが押圧されると、封入すべき品物の排出要求信号が排出要求信号出力手段11から計量機1に出力され(時点a)、またこれとともに、演算手段14は、上記した機械的な遅らせ時間T1から要縦シール時間T2を減じる時間を演算し、上記時点aから所定時間T3が経過するまでの間に計量機1から排出完了信号が出力しない場合、この演算された時間T1−T2がさらに経過した時点bにおいて電磁弁作動信号出力手段15からの信号により電磁弁65を作動させ、接離用シリンダ67を駆動して縦シールベルト66を包材fの縦の合わせ目に要縦シール時間T2だけ圧接させて所要の縦シールを施す。
【0016】
一方、この排出要求信号が出力したにも拘らず計量機1から排出完了信号が出力しない場合にはタイマ13は作動せず、したがって、プルダウン機構5及び横シール機構7は作動を停止したままの状態を保つ。
【0017】
そして、1包装サイクル後の2回目の排出要求信号に対しても計量機1が作動せず、時点cにおいてn回目の排出要求信号に対して計量機1から排出完了信号が出力したら、排出完了信号入力手段12からの信号によって作動したタイマ13からの機械的な遅らせ時間T1経過後の出力信号により、電磁弁65及びプルダウン機構5と横シール機構7の各駆動モータ52、72は、時点dにおいてそれぞれ縦シールベルト66、プルダウンベルト51及び横シールジョー71を作動させて所定の包装動作に入らせる。
【0018】
そしてこの動作により、包材fの縦の合わせ目には、1回目の縦シールベルト66の圧接により所要の縦シールが完了しているため、袋は最初から完全なものとして成形され排出される。
【0019】
そしてさらに、n+1回目以降の排出要求信号に対して計量機1から排出完了信号が出力すると、電磁弁65及び、プルダウン機構5と横シール機構7の各駆動モータ52、72は、それぞれ縦シールベルト66及びプルダウンベルト51と横シールジョー71を引き続き作動させて連続包装動作を行わせる。
【0020】
これに対して図4に示した動作タイミングは、包材fの種類により要縦シール時間T2が機械的な遅らせ時間T1よりも長い場合についてのものである。
【0021】
すなわち、この場合の動作タイミングは、予め演算手段14にこの長い要縦シール時間T2が入力された状態のもとで図示しない操作スイッチが入れられると、要縦シール時間T2が機械的な遅らせ時間T1よりも長いため、電磁弁作動信号出力手段15は、排出要求信号の出力時点aから所定時間T3が経過する時点よりも|T1−T2|時間だけ早い時点、例えば、b’で電磁弁65を作動させ、縦シールベルト66により包材fに所要の縦シール処理をさせて、以後は、さきに述べたと同様の動作をもって包装作業を行う。
【0022】
なお、以上は包装機の停止後の操作スイッチが押圧された後の1回目の排出要求信号に対して計量機1から排出完了信号が出力しない場合について説明したものであるが、1回目の排出要求信号に対して計量機1から直ちに排出完了信号が出力した場合には、要縦シール時間T2が機械的な遅らせ時間T1よりも短い場合は、図6に示したように、また要縦シール時間T2が機械的な遅らせ時間T1よりも長い場合は、図7に示したように、電磁弁65への通電の前または後に引続いてタイマー13が作動し、機械的な遅らせ時間T1の経過後にプルダウン機構5及び横シール機構7が作動を始めることは云うまでもない。
【0023】
さらに、図6及び図7に示したように、2回目の排出要求信号に対しても計量機1から排出完了信号が出力すると、電磁弁65及び、プルダウン機構5と横シール機構7の各駆動モータ52、72は、それぞれ縦シールベルト66及びプルダウンベルト51と横シールジョー71を引き続いて作動させて連続包装動作を行わせる。
【0024】
そして、例えば3回目の排出要求信号に対して、所定時間T3が経過しても計量機1から排出完了信号が出力しない場合には、機械的な遅らせ時間T1の経過後に電磁弁65の作動を止めて縦シールベルト66を包材fの縦の合わせ目から離すとともに、横シール機構7の駆動モータ72を停止して横シールジョー71を原点位置Oに停止させ、さらに、プルダウン機構5の駆動モータ52を減速させつつ停止し、つまり、プルダウンベルト51による包材fの移送速度を減速させながら、縦シールされた部分の上端部が縦シールベルト66の下端部よりも若干上方に位置するまで包材fを移送して駆動モータ52を停止させる。この時迄に、1回目及び2回目の排出要求信号に応答して排出された品物は、すでに各々包装されている。
【0025】
そして、4回目の排出要求信号からはさきに述べた図3または図4と同様の動作、あるいは図6及び図7についてさきほど述べた動作を行う。
なお、図3、図4、図6及び図7において、2回目からの排出要求信号は周期的に自動的に計量機1へ出力される。
【0026】
以上は、連続的に包装動作を行う包装機の場合について本発明を説明したものであるが、間欠的に包装動作を行う包装機にも本発明を適用することができる。
【0027】
【発明の効果】
以上述べたように本発明によれば、計量機への最初の排出要求信号出力時に縦シール手段を作動させるとともに、計量機からの排出完了信号を待って包材移送手段と横シール手段を作動させるような制御手段を設けたので、計量機からの排出完了信号が跡絶えても、最初の排出要求信号出力時に確実な縦シール処理を行わせることにより、品質良好な袋を当初から成形することを可能にする。

BACKGROUND OF THE INVENTION
The present invention relates to a packaging machine, and more particularly to a vertical seal control device in a packaging machine.
[0002]
[Prior art]
The thermoplastic belt-shaped packaging material is transferred along the peripheral surface of the filling cylinder while being bent into a cylindrical shape by a former, and the vertical edges overlapped in the meantime are sealed by a vertical seal heater and below the filling cylinder. In a packaging machine that seals the top part of the bag and the ground part of the next bag at the same time with a horizontal seal heater arranged on the packaging machine, that is, a packaging machine called a vertical pillow packaging machine, A belt-type vertical seal mechanism is used as a means for fusing the contents, and the contents are filled and packaged continuously.
[0003]
This type of packaging machine does not stop the feeding of the packaging material unless it causes a problem, but the packaging machine owner / supplier supplies the goods to be filled from the weighing machine in response to the discharge request signal from the packaging machine. In the case of a measuring machine slave system, if the product is not supplied for some reason, the transport of the packaging material is temporarily stopped to separate the heater belt from the packaging material. In this case, the heater belt once contacts the vertical edge of the packaging material and repeatedly heats the same part in preparation for the next packaging. Inconveniences such as creating defective bags.
[0004]
On the other hand, if the feeding of the packaging material and the heater belt are actuated at the same time, the vertical sealing of the packaging material at the beginning of feeding cannot be performed sufficiently. This causes inconveniences such as damage to the surroundings and scattering of the filled product.
[0005]
[Problems to be solved by the invention]
The present invention has been made in view of such problems, and the object of the present invention is to provide a new packaging machine that does not produce a defective package even when the product is supplied and then restarted. There is to do.
[0006]
[Means for Solving the Problems]
That is, in order to achieve the above object, the present invention is a packaging machine in which a thermoplastic belt-like wrapping material is bent into a cylindrical shape, and transported and laterally sealed while applying a vertical seal to the edge in the transport direction. It actuates the longitudinal sealing means for a time that can seal the strip packaging material emissions when request signal output to the weighing machine and a packaging material transfer means and the transverse sealing means waiting for the discharge completion signal from the weighing machine operated in Control means for performing control is provided.
[0007]
[Action]
With this configuration, the vertical packing is performed on the packaging material for the time required to issue the first discharge request signal to the weighing machine, and the operation of the pull-down mechanism and the horizontal sealing mechanism indicates the discharge completion signal from the weighing machine. By carrying out after waiting, it is possible to form a bag with a reliable seal from the beginning of the supply of goods.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Therefore, examples of the present invention will be described below.
All the drawings show one embodiment of the present invention.
[0009]
Below the weighing machine 1 having a large number of weighing heads, a hopper 2 for receiving the weighed and released items is arranged, and below this is a former 3 for bending the packaging material f into a cylindrical shape. A pull-down mechanism 5 for transferring the bent packaging material f to the horizontal sealing mechanism 7 and a vertical sealing mechanism 6 for providing a vertical seal at the vertical joint of the packaging material f are provided.
[0010]
FIG. 2 shows a vertical seal mechanism disclosed by the present applicant in Japanese Patent Application Laid-Open No. 6-239318. The vertical seal mechanism 6 disposed around the filling cylinder 4 together with the pull-down belt 51 includes a support pin 61. The vertical seal unit 63 can be separated from the filling cylinder 4 when the filling cylinder 4 is replaced by the swing arm 62 that swings around the fulcrum. Further, the vertical sealing belt 66 is attached to the filling cylinder 4 on the swing arm 62. A size-changing motor 64 that is positioned at a position corresponding to the diameter of the belt, and a belt contact / separation mechanism that operates by operating the electromagnetic valve 65 to release the pressing of the vertical seal belt 66 from the surface of the packaging material f when the apparatus stops. A cylinder 67 is provided.
[0011]
In the drawing, reference numeral 68 denotes a seal position changing knob, and 69 denotes a sleeve that changes the angle of the vertical seal belt 66 with which the packaging material f contacts.
[0012]
Returning to FIG. 1 again, reference numeral 10 in the drawing is a control circuit that forms part of the packaging machine itself or a host computer that controls the entire packaging system. This control circuit 10 measures the operation by pressing an operation switch (not shown). A discharge request signal output means 11 for outputting a discharge request signal to the machine 1, a discharge completion signal input means 12 for receiving a discharge completion signal from the weighing machine 1 and outputting a signal to the timer 13, and a discharge completion signal After a mechanical delay time T1 (described later), a mechanical delay is generated by the timer 13 that outputs an operation signal to the drive motor 52 of the pull-down mechanism 5 and the arm drive motor 72 of the lateral seal mechanism 7 and the pressing of the operation switch. The calculation means 14 for subtracting the required vertical seal time T2 (described later) from the time T1 and outputting the T1-T2 signal to the solenoid valve actuation signal output means 15, and the calculation at first. The operation signal is output by the output signal from the stage 14, and then the operation signal output means 15 for outputting the operation signal to the electromagnetic valve 65 after waiting for the signal from the timer 13, and the vertical direction of the packaging material f by type. The packaging material information input means 16 inputs the sealing time T2 to the calculation means 14.
[0013]
Note that the mechanical delay time T1 described above means that the jaw 71 of the lateral seal mechanism 7 also moves from the origin position 0 when the product discharged from the weighing machine 1 reaches the meshing point as shown in FIG. The time required to delay the operation of the horizontal sealing mechanism 7 and the pull-down mechanism 5 so that the meshing point is reached and the conveyance of the packaging material f starts from this point, and the vertical sealing time required. T2 refers to the time required to ensure vertical sealing over the entire distance between the pulleys of the vertical seal belt 66 according to the type of the packaging material f.
[0014]
Next, the packaging operation of the packaging machine configured as described above will be described based on the operation timing shown in FIG.
[0015]
When the operation switch is pressed under the condition that the required vertical sealing time T2 corresponding to the type of the packaging material f is previously input from the packaging material information input means 16 to the calculation means 14, the discharge request signal for the item to be enclosed Is output from the discharge request signal output means 11 to the weighing machine 1 (time point a). At the same time, the calculation means 14 calculates a time for subtracting the required vertical seal time T2 from the mechanical delay time T1 described above. If the discharge completion signal is not output from the weighing machine 1 until the predetermined time T3 elapses from the time point a, the signal from the solenoid valve operation signal output means 15 at the time point b when the calculated time T1-T2 further elapses. Thus, the electromagnetic valve 65 is actuated to drive the contacting / separating cylinder 67 so that the vertical seal belt 66 is brought into pressure contact with the vertical joint of the packaging material f for the required vertical seal time T2 to provide the required vertical seal.
[0016]
On the other hand, if the discharge completion signal is not output from the weighing machine 1 in spite of the output of the discharge request signal, the timer 13 does not operate, and therefore the pull-down mechanism 5 and the lateral seal mechanism 7 remain stopped. Keep state.
[0017]
When the weighing machine 1 does not operate for the second discharge request signal after one packaging cycle and the discharge completion signal is output from the weighing machine 1 for the nth discharge request signal at time point c, the discharge is completed. By the output signal after the mechanical delay time T1 from the timer 13 activated by the signal from the signal input means 12, the drive motors 52 and 72 of the electromagnetic valve 65, the pull-down mechanism 5 and the lateral seal mechanism 7 are timed d. Then, the vertical seal belt 66, the pull-down belt 51, and the horizontal seal jaw 71 are actuated to enter a predetermined packaging operation.
[0018]
By this operation, since the required vertical sealing is completed by the first press of the vertical seal belt 66 at the vertical joint of the packaging material f, the bag is completely formed and discharged from the beginning. .
[0019]
Further, when a discharge completion signal is output from the weighing machine 1 in response to the discharge request signal for the (n + 1) th and subsequent times, the solenoid valve 65 and the drive motors 52 and 72 of the pull-down mechanism 5 and the lateral seal mechanism 7 are respectively connected to the vertical seal belt. 66, the pull-down belt 51 and the lateral seal jaw 71 are continuously operated to perform a continuous packaging operation.
[0020]
On the other hand, the operation timing shown in FIG. 4 is for the case where the required vertical sealing time T2 is longer than the mechanical delay time T1 depending on the type of the packaging material f.
[0021]
That is, the operation timing in this case is such that when the operation switch (not shown) is turned on in a state where the long vertical seal time T2 is previously input to the computing means 14, the vertical seal time T2 is mechanically delayed. Since it is longer than T1, the solenoid valve actuating signal output means 15 outputs the solenoid valve 65 at a time that is | T1-T2 | time earlier than the time when the predetermined time T3 has elapsed from the output time point a of the discharge request signal. And the required vertical sealing process is performed on the packaging material f by the vertical sealing belt 66, and thereafter, the packaging operation is performed with the same operation as described above.
[0022]
In addition, although the above demonstrated the case where the discharge completion signal was not output from the weighing machine 1 with respect to the 1st discharge request signal after the operation switch after a packaging machine stop was pressed, it is 1st discharge When a discharge completion signal is immediately output from the weighing machine 1 in response to the request signal, if the required vertical sealing time T2 is shorter than the mechanical delay time T1, as shown in FIG. When the time T2 is longer than the mechanical delay time T1, as shown in FIG. 7, the timer 13 is operated before or after the solenoid valve 65 is energized, and the mechanical delay time T1 has elapsed. Needless to say, the pull-down mechanism 5 and the lateral seal mechanism 7 start to operate later.
[0023]
Further, as shown in FIGS. 6 and 7, when a discharge completion signal is output from the weighing machine 1 in response to the second discharge request signal, each drive of the solenoid valve 65, the pull-down mechanism 5 and the lateral seal mechanism 7 is driven. The motors 52 and 72 continuously operate the vertical seal belt 66, the pull-down belt 51, and the horizontal seal jaw 71, respectively, to perform a continuous packaging operation.
[0024]
For example, if the discharge completion signal is not output from the weighing machine 1 even after the predetermined time T3 has elapsed with respect to the third discharge request signal, the electromagnetic valve 65 is operated after the mechanical delay time T1 has elapsed. At the same time, the vertical seal belt 66 is separated from the vertical joint of the packaging material f, the drive motor 72 of the horizontal seal mechanism 7 is stopped, the horizontal seal jaw 71 is stopped at the origin position O, and the pull-down mechanism 5 is driven. The motor 52 is stopped while being decelerated, that is, the upper end portion of the vertically sealed portion is positioned slightly above the lower end portion of the vertical seal belt 66 while the transfer speed of the packaging material f by the pull-down belt 51 is reduced. The packaging material f is transferred and the drive motor 52 is stopped. By this time, the items discharged in response to the first and second discharge request signals are already packaged.
[0025]
Then, from the fourth discharge request signal, the operation similar to FIG. 3 or FIG. 4 described above or the operation described above with reference to FIG. 6 and FIG. 7 is performed.
3, 4, 6, and 7, the discharge request signal from the second time is automatically and periodically output to the weighing machine 1.
[0026]
The above is the description of the present invention in the case of a packaging machine that continuously performs a packaging operation, but the present invention can also be applied to a packaging machine that performs an intermittent packaging operation.
[0027]
【The invention's effect】
As described above, according to the present invention, the vertical sealing means is activated when the first discharge request signal is output to the weighing machine, and the packaging material transfer means and the horizontal sealing means are activated after waiting for the discharge completion signal from the weighing machine. Since the control means is provided, even if the discharge completion signal from the weighing machine is traced, a good quality bag is formed from the beginning by performing a reliable vertical sealing process when the first discharge request signal is output. Make it possible.
