Description
【０００１】[0001]
本考案は、袋の中の液状被包装物の爆発的な沸騰を抑えるための仮シール装置 に関する。 The present invention relates to a temporary sealing device for suppressing explosive boiling of liquid packaged items in a bag.
【０００２】[0002]
従来、実公昭４４−８３８４号公報には、図４に示すごとく袋(1) に充填した 被包装物(2) を真空包装するのに先立って、袋口に仮シール(3) を施し、各仮シ ール部分の間にオリフイス(4) を形成することが開示されている。液を含んだ被 包装物の場合、袋の内部圧力を急速低下させると、差圧によって被包装物は爆発 的な沸騰現象を起こすので、前記技術は、袋口にオリフイスを形成して袋内圧力 が急速低下するのを防止している。また特開昭６２−５２０２２号公報には、図 ５に示す如く上下２本のシールバー(5)(6)を矢印の如く相反する方向に移動させ 、上下に点在的に膨出した仮シール部(7)(8)の間のオリフイスの大きさを調整す るようにしたものを開示している。低温に比べて高温の被包装物の場合は儘かな 真空圧力の降下で沸騰するで、当該公報ではオリフイスの大きさを任意に調整で きる。 Conventionally, in Japanese Utility Model Publication No. 44-8384, as shown in FIG. 4, a temporary seal (3) is applied to the bag mouth prior to vacuum-packing the object (2) filled in the bag (1), It is disclosed to form an orifice (4) between each temporary seal portion. In the case of a packaged product containing liquid, if the internal pressure of the bag is rapidly lowered, the packaged product will explode due to the differential pressure. It prevents the pressure from dropping rapidly. Further, in JP-A-62-52022, as shown in FIG. 5, two upper and lower seal bars (5) and (6) are moved in opposite directions as indicated by arrows to temporarily swell vertically. It discloses that the size of the orifice is adjusted between the seal portions (7) and (8). In the case of an object to be packaged that has a higher temperature than that of a low temperature, it will boil due to a slight drop in vacuum pressure. Therefore, in this publication, the size of the orifice can be arbitrarily adjusted.
【０００３】[0003]
しかし図５のものは、すべて作業員がオリフイスの調整作業を行なうもので、 被包装物の温度とオリフイスの大きさと正確に割出すことができない欠点がある 。 However, in the case of Fig. 5, all the workers perform the adjustment work of the orifice, and there is a drawback that the temperature of the package and the size of the orifice cannot be accurately determined.
【０００４】[0004]
本考案は、被包装物の温度数値に応じて、仮シールオリフイスの開角を自動的 かつ段階的に選択するようにしたもので、そのための手段として、無端軌道の外 側から供給される空袋を該無端軌道に沿って１ピッチづつ間欠的に搬送する手段 と、前記無端軌道を搬送中の空袋に被包装物を充填する手段及び被包装物を充填 した袋を無端軌道外に排除する手段とからなるロータリ式袋詰機において、前記 無端軌道における袋の搬送方向に向って、空袋に被包装物を充填するセクション の後位で、袋口を隔てて平行状に対設する一側の加熱バー(28)及び他側のロール 状体(299と、前記ロール状体の周面に軸方向に沿って膨出した複数本の突条堤(4 2)(43)…と、前記突条堤の外面に各突条堤間でそれぞれピッチ差が生ずるように 形成した多種類の不連続突起(45)と、前記ロール状体(29)に連続したモータ(47) と、前記袋内に充填される被包装物の温度検出器(26)と、前記温度検出器(26)が 測定した温度数値に応じて前記モータ(47)の回転角を選択する指令信号をモータ に送る制御器(27)と、前記加熱バー(28)とロール状体(28)との間で袋が停止した とき、該加熱バー及びロール状体を袋口に向って接近させる機構(39)とにより構 成したものである。 According to the present invention, the opening angle of the temporary seal orifice is automatically and stepwise selected according to the temperature value of the object to be packaged. As a means for that, the space supplied from the outside of the endless track is used. A means for intermittently transporting the bag one pitch at a time along the endless track, a means for filling an empty bag which is being transported through the endless track with a packaged object, and a bag filled with the packaged object is excluded from the endless track.

Specifically, the bag packing machine has a circular rotor (21) peripheral surface. Clampers (23) and (23) are provided at the tips of a pair of arms (22) projecting to each side, and the bags (1 2) supported by these clampers are conveyed by one pitch in the arrow direction (24) by the rotation of the rotor (21). To do. The section (15) is equipped with a nozzle (25) for replenishing the seasoning liquid and a radiant temperature sensor (26), and the temperature of the object to be packed in the bag (12) is detected by the temperature sensor (26). Measure with and digitize with the controller (27). Further, in the next section (16), a heating bar (28) and a roll-shaped body (29) are provided opposite to each other across the opening edge of the bag (12). As shown in FIG. 2, two shafts (33) and (34) are supported on a frame (32) fixed to the machine base (31) so as to be opposed to the rotor (21). While engaging the pair of gears (35) (36) fixed to, the heating bar (28) to the arm (37) fixed to the shaft (33) on one side and the shaft (34) on the other side. The roll-shaped bodies (29) are respectively supported by the fixed arms (38), and a fluid cylinder (39) is installed between the arms (38) and the frame (32). When the piston rod (40) is pushed out by the pressure fluid acting on the fluid cylinder (39) and one arm (38) is rotated around the shaft (34), the meshing of the paired gears (35) (36) causes The other arm (37) also rotates so that the heating bar (28) and the roll-shaped body (29) approach toward the bag mouth.
【０００８】 またロール状体(29)の周面には軸方向に沿って複数本の細長い突条堤(42)(43) (44)…を形成している。図１のように各突条堤の外側の面には多数の突起(45)を 不連続な状態で軸方向に沿って設けているが、各突条堤にそれぞれ形成した不連 続突起(45)の相互間にはピッチ差がある。すなわち不連続突起の間のオリフイス (46)の大きさは各突条堤ごとに相違する。さらに前記ロール状体(29)の軸と連続 するように両側の腕(38)の外側にモータ(47)とエンコーダ(48)とを設けると共に 、前記制御器(27)とモータ及びエンコーダとを回路(49)(50)を介して連結してい る。そこで温度検出器(26)が被包装物の温度を制御器(27)に入力すると、該制御 器(27)は前記温度数値に応じた信号を回路(49)を介してモータ(47)に送信する。 そしてモータ(47)はエンコーダ(48)からのフイードバック信号との関係において 温度数値分だけロール状体(29)を回転する。被包装物の温度を１０℃単位で割っ て制御器(27)に記憶させ、図３Ａの如く９０℃〜１００℃では第１突条堤(42)を 、８０℃〜９０℃では第２突条堤(43)を、また７０℃〜８０℃では第３突条堤(4 4)を加熱バー(28)と対向するようにモータ(47)を回転させる。被包装物が高温な ほど仮シールオリフイスを小さくするように制御して、真空下での被包装物の急 激な沸騰を抑えるものである。なお温度検出器の種類並びに加熱バーとロール状 体とを接近させる機構は、図示した構造に限定されるものではない。A plurality of elongated projecting ridges (42) (43) (44) ... Are formed along the axial direction on the peripheral surface of the roll-shaped body (29). As shown in Fig. 1, a large number of protrusions (45) are provided in the axial direction in the discontinuous state on the outer surface of each rib, but the discontinuous protrusions ( There is a pitch difference between 45). That is, the size of the orifice (46) between the discontinuous projections differs for each projecting ridge. Further, a motor (47) and an encoder (48) are provided outside the arms (38) on both sides so as to be continuous with the axis of the roll-shaped body (29), and the controller (27), motor and encoder are connected. They are connected via circuits (49) (50). Then, when the temperature detector (26) inputs the temperature of the packaged object to the controller (27), the controller (27) sends a signal corresponding to the temperature value to the motor (47) via the circuit (49). Send. Then, the motor (47) rotates the roll-shaped body (29) by the temperature numerical value in relation to the feedback signal from the encoder (48). Divide the temperature of the packaged item by 10 ℃ and store it in the controller (27). As shown in Fig. 3A, the first projecting ridge (42) is at 90 ℃ to 100 ℃, and the second projection is at 80 ℃ to 90 ℃. A motor (47) is rotated so that the bank (43) and the third projecting bank (44) at 70 ° C to 80 ° C face the heating bar (28). The temporary seal orifice is controlled to be smaller as the temperature of the object to be packaged becomes higher, and the rapid boiling of the object to be packaged under vacuum is suppressed. The type of the temperature detector and the mechanism for bringing the heating bar and the roll-shaped body close to each other are not limited to the illustrated structure.

温度検出器(26)で測定した被包装物の温度数値から割出した信号でロール状体 (29)の回転角を制御し、ピッチ差のある複数の不連続突起を自動的に選択して仮 シールを行なうようにしたから、従来の作業員によるシール選択に比べて仮シー ルオリフイスの選択が正確になり、真空下での高温被包装物の沸騰を正確に制御 できる効果がある。 The rotation angle of the roll-shaped body (29) is controlled by a signal calculated from the temperature value of the packaged product measured by the temperature detector (26), and a plurality of discontinuous protrusions with different pitches are automatically selected. Since temporary sealing is performed, the selection of the temporary seal orifice is more accurate than the conventional seal selection by workers, and the boiling of the high-temperature packaged object under vacuum can be controlled accurately.
