操作者(作業者)將被包裝物20載置在供給輸送帶3，將操作盤13的包裝開始鈕(無圖示)按下的話，供給輸送帶3，是從被安裝於傳導、控制盒9的外側的供給輸送帶馬達M3藉由被安裝於傳導、控制盒9的內側的傳導部9b被驅動。The operator (operator) mounts the packaged article 20 on the supply conveyor 3, and presses the package start button (not shown) of the operation panel 13 to supply the conveyor belt 3, which is attached to the conduction and control box. The supply conveyor motor M3 on the outer side of 9 is driven by the conductive portion 9b attached to the inside of the conduction and control box 9.

同時，設於傳導、控制盒9的控制部9a，是將供給輸送帶3的給進量由包裝長編碼器72檢出，使其控制訊號被輸入。At the same time, the control unit 9a provided in the conduction and control box 9 detects the feed amount of the supply conveyor 3 by the package length encoder 72, and causes the control signal to be input.

縱密封器4、4'，是藉由控制部9a的第2控制電路71，從被安裝於傳導、控制盒9的外側的縱密封器馬達M2藉由被安裝於傳導、控制盒9的內側的傳導部9c被旋轉驅動並藉由成型器2使被形成於三方密封包袋的被包覆薄膜11被縱密封。The vertical sealers 4, 4' are attached to the inside of the conduction and control box 9 from the longitudinal sealer motor M2 attached to the outside of the conduction and control box 9 by the second control circuit 71 of the control unit 9a. The conductive portion 9c is rotationally driven and the coated film 11 formed in the three-way sealed bag is longitudinally sealed by the former 2.

被縱密封的被包覆物20被內包的包覆薄膜11是使中央輸送帶6藉由傳導部9c被驅動，朝一對的橫密封器5、5'被送入。The cover film 11 that is wrapped in the longitudinally sealed article 20 is driven by the conductive portion 9c to be fed to the pair of transverse seals 5, 5'.

設於傳導、控制盒9的控制部9a，是檢出橫密封器5、5'的運動從橫密封器原點感測器74、橫密封器變速感測器75使控制訊號被輸入。The control unit 9a provided in the conduction and control box 9 detects the movement of the transverse seals 5, 5' from the transverse seal origin sensor 74 and the transverse seal shift sensor 75 to input a control signal.

雙曲軸機構35，是藉由控制部9a的第1控制電路70，以由橫密封器驅動馬達M1被驅動的橫密封器驅動齒輪33及由橫密封器從動齒輪32所構成的驅動部34被轉動的橫密封器曲軸30被運動變換藉由下密封器連接桿52將一對的橫密封器5、5'的下密封器5朝上下驅動，並且由橫密封器曲軸28被運動變換藉由上密封器連接桿26將一對的橫密封器的上密封器5'朝上下驅動。如此，雙曲軸機構35是與包裝薄膜11的搬運速度同步使彼此之間接近/遠離的方式，即偏離180°相位地使一對的橫密封器5、5'朝上下驅動(第6圖(a)、(b))。The double crank mechanism 35 is a first seal circuit 35 of the control unit 9a, a transverse sealer drive gear 33 driven by the transverse sealer drive motor M1, and a drive unit 34 composed of a transverse sealer driven gear 32. The rotated transverse sealer crankshaft 30 is moved by the lower sealer connecting rod 52 to drive the lower seals 5 of the pair of transverse seals 5, 5' upward and downward, and is moved by the transverse sealer crankshaft 28 The upper seal 5' of the pair of transverse seals is driven up and down by the upper seal connecting rod 26. In this manner, the double crank mechanism 35 is in such a manner as to be close to/away from each other in synchronization with the conveyance speed of the packaging film 11, that is, the pair of horizontal seals 5, 5' are driven up and down by a phase deviation of 180 (Fig. 6 (Fig. 6 ( a), (b)).

同時，滑件曲軸機構50，是以由橫密封器驅動馬達M1被驅動的橫密封器驅動齒輪33及由橫密封器從動齒輪32所構成的驅動部34使橫密封器曲軸30被轉動，且藉由橫密封器滑件52a在定位置被固定於線性桿56且被卡止於可擺動自如的橫密封器擺動軸54的兩端部滾子51是嵌合於長孔52b藉由橫密封器曲軸30的轉動而擺動作滑動使一對的橫密封器5、5'擺動(第4圖(a)、(b))。At the same time, the slider crank mechanism 50 rotates the transverse seal crankshaft 30 by the transverse sealer drive gear 33 driven by the transverse sealer drive motor M1 and the drive portion 34 constituted by the transverse sealer driven gear 32. And the both ends of the roller 51 which are fixed to the linear rod 56 at a fixed position by the horizontal seal slider 52a and locked to the swingable horizontal seal swing shaft 54 are fitted to the long hole 52b by the horizontal When the sealer crankshaft 30 rotates and swings, the pair of horizontal seals 5, 5' are swung (Fig. 4 (a), (b)).

即，藉由滑件曲軸機構50，從朝包裝薄膜11的接觸時點La直到遠離包裝薄膜11的時點Lb為止與包裝薄膜11的搬運速度同步地使一對的橫密封器5、5'移動，從遠離包裝薄膜11的時點Lb直到朝包裝薄膜11的接觸時點La為止從包裝薄膜11的搬運速度變速使一對的橫密封器5、5'擺動(第7圖、第8圖)。In other words, the pair of transverse seals 5, 5' are moved by the slider crank mechanism 50 in synchronization with the conveyance speed of the packaging film 11 from the contact point La of the packaging film 11 to the time point Lb away from the packaging film 11. The pair of horizontal seals 5, 5' are swung from the time point Lb away from the packaging film 11 until the contact point La of the packaging film 11 from the conveyance speed of the packaging film 11 (Fig. 7 and Fig. 8).

此情況，如第7圖、第8圖所示，一對的橫密封器5、5'因為是挾持通過包覆被包覆物20的包裝薄膜11的中心線CL朝上下方向重疊，所以其遊隙可由被設在上密封器21的彈簧23吸收。又，此彈簧23也可達成適度限制對於一對的橫密封器5、5'的包裝薄膜11的熔接熔斷壓力的功能。In this case, as shown in Fig. 7 and Fig. 8, the pair of transverse seals 5, 5' are stacked in the vertical direction by the center line CL of the packaging film 11 covering the coated article 20, so that The play can be absorbed by the spring 23 provided at the upper sealer 21. Moreover, the spring 23 can also function to appropriately limit the welding fusing pressure to the packaging film 11 of the pair of transverse seals 5, 5'.

如此一對的橫密封器5、5'可描畫合成了偏離180°相位的上下動、及往復擺動的如第7圖所示的合成軌跡UL、LL地進行運動，藉由一對的橫密封器5、5'的熔接熔斷，使供給輸送帶3的給進量對應由包裝長編碼器72被測量且由設定操作盤10被設定的參數形成預定包袋長的三方密封包袋20a。The pair of transverse seals 5, 5' can be drawn by synthesizing the up and down movements offset from the 180° phase and the reciprocating oscillations of the synthetic tracks UL, LL as shown in Fig. 7, by a pair of transverse seals. The welding of the feeders 5, 5' is blown such that the feed amount of the supply conveyor 3 corresponds to the three-way sealed bag 20a of the predetermined bag length corresponding to the parameter measured by the package length encoder 72 and set by the setting operation panel 10.

如此的話被形成的三方密封包袋20a，是藉著由傳導部9c被驅動的搬出輸送帶7被搬出。In this way, the three-way sealed bag 20a formed is carried out by the carry-out belt 7 driven by the conductive portion 9c.
