Abstract

<P>PROBLEM TO BE SOLVED: To efficiently degas and tightly seal a package produced by a bag making/filling/packaging machine. <P>SOLUTION: A plurality of elastic blocks 38 are moved down by a linear motor 27 from above and press a solid food product in each of a plurality of packaging bodies 30 relative to a plurality of wrapping materials 30 on the second conveyor 25 transported one after another. By the movement 49 of each slider 29 along a guide 26, the blocks 38 are rotated integrally with a spur gear 39 engaged with a rack tooth 40, the packages 30 are rotated by 90° for directionally changing each package 30 from a vertically long condition to a horizontally long condition and then they are transported into a vacuum packaging pressure-proof chamber reciprocally moving with the same speed as the second belt conveyer 65. In this case, the rotary speed of the conveyer 65 is lower than the speed of the taking-out convey 25 and by the difference in speed, the gap between the packages 30 transported on the conveyer 65 becomes smaller for reducing the volume of the chamber and for increasing packaging efficiency. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

本発明は、例えば解体した鶏の１つの背肉、或いは複数の食品をトレイ内に収容して１つに固体化したものなど、こうした固体食品の複数個を一括して真空包装する方法及び装置に関する。   The present invention relates to a method and apparatus for collectively vacuum packaging a plurality of such solid foods such as one back meat of a disassembled chicken or a plurality of foods contained in a tray and solidified into one. About.

縦列等間隔で運搬する被包装物と同速移動する帯状の包材を、前記の被包装物の周りでチューブ化する一方、前記各被包装物の間で前記のチューブ状包材をロータリカッターでカットして形成した包装体を産出する製袋充填包装機構と、包装体の真空包装用機器とを縦列状に並べ、前記の製袋充填包装機構から搬出する各包装体を、該被包装物の搬送軌道に沿って往復動する真空包装用機器の大容量耐圧チャンバー内に複数個単位で運びいれ、該耐圧チャンバー内において複数個の包装体を同時に脱気包装する技術を、下記の特許文献１は開示する。   While the strip-shaped packaging material moving at the same speed as the packages to be transported at equal intervals in a column is tube-shaped around the packages, the tubular packaging material is rotated between the packages to be rotated. The bag making and filling and packaging mechanism for producing the package formed by cutting in the above and the vacuum packaging equipment for the packaging are arranged in a tandem shape, and each package to be taken out from the bag making and filling and packaging mechanism is packaged. The following patent is a technology for carrying a plurality of units into a large-capacity pressure-resistant chamber of a vacuum packaging device that reciprocates along a product transport path, and simultaneously degas-packaging a plurality of packages in the pressure-resistant chamber. Document 1 discloses.

一方、下記の特許文献２には、製袋充填包装機構が形成する包装体を、往復動する耐圧チャンバーに順次搬入して１個づつ脱気シールする装置を開示するが、一般に、製袋充填包装機構は、１秒／１袋の製袋充填能力は充分あるから、このように１袋単位で包装体を収容する容積しか備えない耐圧チャンバーでは、その往復運動の半工程つまり０．５秒しか包装体に真空を作用させことしかできず効率が悪く、この点、前記の特許文献１に図示される４袋の包装体の１度に収容する容積を備える耐圧チャンバーは、少なくともその往復運動の半工程つまり２．０秒間、包装体に真空を作用させることができ能率的である。   On the other hand, the following Patent Document 2 discloses a device for sequentially carrying the package formed by the bag making and filling mechanism into a pressure chamber that reciprocates and degassing and sealing them one by one. Since the packaging mechanism has sufficient bag making and filling capacity of 1 second per bag, in such a pressure resistant chamber having only a capacity for accommodating a package in units of one bag, half a step of the reciprocating motion, that is, 0.5 seconds. However, the vacuum can only be applied to the package, and the efficiency is poor. In this respect, the pressure-resistant chamber provided with a capacity for accommodating the package of the four bags illustrated in Patent Document 1 is at least reciprocating. It is efficient that a vacuum can be applied to the package for half a step, that is, for 2.0 seconds.

しかし前記の発明は、その耐圧チャンバーに複数（例えば４袋）の包装体を長手方向に縦列状に搬入する構成であり、各包装体開口縁のシール台は、包装体の搬入軌道と交差していて運び入れる包装体の障害となるので、多数のシール台をコンベヤでもって各包装体と同調移動させる対策が不可欠で、構造が複雑である。また耐圧チャンバーは縦列する４袋の包装体を長手方向に収容する関係で、それだけの容積が必要であり、定められた時間にその容積分に相当する運動が必要で、その間のシーラ操作に必要な時間を差し引くと実質的な真空時間が短縮するという問題がある。   However, the invention described above is configured to carry a plurality (for example, four bags) of packaging bodies in the longitudinal direction in the pressure-resistant chamber, and the sealing base at the opening edge of each packaging body intersects with the packaging track. Therefore, it is indispensable for the package to be carried in, and therefore, it is indispensable to take measures to move a large number of sealing stands together with each package using a conveyor, and the structure is complicated. In addition, the pressure-resistant chamber accommodates four longitudinally packed packages in the longitudinal direction, so that much volume is required, and movement corresponding to that volume is required at a predetermined time, which is necessary for the sealer operation during that time. However, there is a problem that a substantial vacuum time is shortened if a long time is subtracted.

そこで本発明の方法は、各包装体の搬出コンベヤ上域に、該搬出コンベヤが運び出す複数の包装体と同間隔で弾性ブロックを配置し、該弾性ブロックを、ロータリカッターがチューブ状包材を切断するタイミングに合わせて各包装体それぞれの固体食品上に押し下げかつ前記搬出コンベヤの移動と同方向に同調的に移動する該弾性ブロックの平面方向への回転でもって各包装体を搬出コンベヤ上で９０度角回転させて横向きにする。そのあと、横向きの各包装体を搬出コンベヤから、該搬出コンベヤの移送スピードよりも僅かに遅い第２ベルトコンベヤに移乗させて各包装体の間隔を狭める。
この結果、前記の間隔を狭めた包装体を収容する耐圧チャンバーは小さくなり、その分、耐圧チャンバーにおける真空効率のアップと共に、前記耐圧チャンバーの往復運動量の縮小に伴いその往復運動スピードを落とせるので、シーラ操作時間を正確に割付できて脱気に要する時間を有効に使用でき、またシール台を包装体開口縁の移動方向に沿って設けることができ、従来例の構造の複雑さを解消するなどの効果が期待できるのである。 Therefore, in the method of the present invention, an elastic block is arranged at the same interval as the plurality of packages carried out by the carry-out conveyor in the upper region of the carry-out conveyor of each package, and the rotary cutter cuts the tubular packaging material. Each package is pressed on the unloading conveyor by rotating in the plane direction of the elastic block which is pushed down on the solid food of each package in accordance with the timing of the movement and moves in the same direction as the movement of the unloading conveyor. Rotate the angle to the side. Thereafter, the sideways package bodies are transferred from the carry-out conveyor to a second belt conveyor that is slightly slower than the transfer speed of the carry-out conveyor to narrow the interval between the package bodies.
As a result, the pressure-resistant chamber that accommodates the package with the space narrowed becomes smaller, and accordingly, the vacuum efficiency in the pressure-resistant chamber is increased, and the reciprocating speed of the pressure-resistant chamber can be reduced as the reciprocating speed of the pressure-resistant chamber is reduced. The time required for deaeration can be used effectively because the sealer operation time can be assigned accurately, and the sealing base can be provided along the moving direction of the package opening edge, eliminating the complexity of the structure of the conventional example, etc. The effect can be expected.

図２に平面を示す製袋充填包装機構１０は、ダンサローラ１１を介して下方から溝型のホーマ１２に繰り出す帯状の包材１３を前記ホーマによって筒状に丸めると共に、一対のロール１４間で前記包材１３の両側縁を合掌化した直後、一対の加熱ローラ１５で前記合掌縁を溶着してチューブ状包材２０を形成する。   The bag-making filling and packaging mechanism 10 shown in a plan view in FIG. 2 rolls a belt-like packaging material 13 fed out from below to a groove-shaped former 12 via a dancer roller 11 into a tubular shape by the former and between the pair of rolls 14. Immediately after the both side edges of the wrapping material 13 are made into a palm, the pair of heating rollers 15 welds the joint edges to form a tubular packaging material 20.

一方、前記ホーマの前位に配置した搬入コンベヤ１６は、前記のチューブ状包材２０の内部に固体食品１７を縦列等間隔で搬入する。そして前記チューブ包材の搬送軌道に設置した仮シーラ２１に配置したカッター２２は、各個体食品１７の中間でチューブ状包材２０を切断して、その開口縁に断続シール２３を施した包装体３０を形成する。なお図３に拡大して図示する仮シーラ２１は、３点の断続シール２３を開口縁に施した包装体３０を順次形成し、矢印２５a方向に回転する搬出コンベヤ２５上に運び出すのである。   On the other hand, the carry-in conveyor 16 disposed in front of the homa carries the solid food 17 into the tubular packaging material 20 at equal intervals in the column. And the cutter 22 arrange | positioned at the temporary sealer 21 installed in the conveyance track | orbit of the said tube packaging material cut | disconnects the tubular packaging material 20 in the middle of each solid food 17, and the package body which gave the intermittent seal 23 to the opening edge 30 is formed. The temporary sealer 21 shown enlarged in FIG. 3 forms a package 30 in which three intermittent seals 23 are provided on the opening edge in order, and is carried out onto a carry-out conveyor 25 that rotates in the direction of the arrow 25a.

側面図である図１において、上下一対の仮シーラ２１は、図示矢印２１aのごとく同期回転またはブロックモーション運動するロータリシーラであって、既に説明したように等ピッチでカットした包装体３０を搬出コンベヤ２５に運び出すが、該コンベヤ上域の棒状のガイド２６に、搬出コンベヤ２５上に運び出される各包装体３０の間隔と一致する間隔の、２個のスライダー３２を支持している。また前記の２個のスライダー３２はそれぞれ直動モータ２７を設置し、各直動モータ２７は下方に垂下する直動体にそれぞれソフトなゴム或いは空気枕のような弾性ブロック２８を設置しており、詳しくは図４にその拡大図を示している。   In FIG. 1, which is a side view, a pair of upper and lower temporary sealers 21 are rotary sealers that rotate synchronously or perform a block motion as shown by the arrow 21a in the figure. The two sliders 32 are supported on the bar-shaped guide 26 in the upper area of the conveyor at intervals corresponding to the intervals of the package bodies 30 carried out on the carry-out conveyor 25. Each of the two sliders 32 is provided with a linear motion motor 27, and each linear motion motor 27 is provided with an elastic block 28 such as a soft rubber or air pillow on a linear motion body hanging downward. Specifically, FIG. 4 shows an enlarged view thereof.

すなわち図４において直動モータ２７を流体シリンダーにより形成すると共に、該直動モータを固定したスライダー３２を２本のガイド２６にスライド自在に支持し、また前記の直動モータ２７は上下にストロークする直動体３３垂下している。さらに前記の直動体３３の周りに、周囲に縦方向の滑りキー３４を備える筒材３５を、ボールベアリング３６を介して支持する共に、前記筒材３５の下端に固定した逆溝型の保護材３７の内部に、ウレタンゴム製の弾性ブロック２８を支持する。一方、前記筒材３５の周りの滑りキー３４に係合する状態で該筒材の周りに配置した平歯車３９を、機台４１に固定して横方向に長いラック歯４０に係合して回転発生機構３１を構成する。   That is, in FIG. 4, the linear motion motor 27 is formed of a fluid cylinder, and a slider 32 to which the linear motion motor is fixed is slidably supported by two guides 26, and the linear motion motor 27 strokes up and down. The linear motion body 33 hangs down. Further, around the linear motion body 33, a cylindrical member 35 provided with a vertical sliding key 34 is supported via a ball bearing 36, and a reverse groove type protective member fixed to the lower end of the cylindrical member 35. An elastic block 28 made of urethane rubber is supported inside 37. On the other hand, a spur gear 39 arranged around the cylindrical member 35 in a state of engaging with the sliding key 34 around the cylindrical member 35 is fixed to the machine base 41 and engaged with the rack teeth 40 which are long in the lateral direction. The rotation generating mechanism 31 is configured.

なお、図１においてロータリカッター２１を駆動する原動軸４３はパルス発生器４４を備え、該パルス発生器４４から発信されるパルス信号４５を読み取る制御器４６は、ロータリカッター２１によるチューブ状包材２０の切断のタイミングに合わせて回転発生機構３１の操作をコントロールするようにしている。   In FIG. 1, the driving shaft 43 that drives the rotary cutter 21 includes a pulse generator 44, and the controller 46 that reads the pulse signal 45 transmitted from the pulse generator 44 is a tubular packaging material 20 formed by the rotary cutter 21. The operation of the rotation generating mechanism 31 is controlled in accordance with the cutting timing.

すなわち複数の直動モータ２７はそれぞれ、ロータリカッター２１がチューブ状包材２０をカットするのと同時に、図５のように上から弾性ブロック２８を下降させて包装体３０内部の固体食品１７に押し付ける。この場合、周囲に滑りキー３４を備える筒材３５は平歯車３９の内部の溝に沿って下降する。その直後、制御器から信号を受けた図４における正逆転モータ４７はボールねじ４８を回転させ、該ボールねじ４８のスクリュー作用でもって直動モータ２７などをガイド２６に沿って往復移動させる。   That is, each of the plurality of linear motion motors 27 lowers the elastic block 28 from above and presses it against the solid food 17 inside the package 30 as shown in FIG. 5 at the same time that the rotary cutter 21 cuts the tubular packaging material 20. . In this case, the tubular member 35 having the sliding key 34 around the lower part moves down along the groove inside the spur gear 39. Immediately thereafter, the forward / reverse motor 47 in FIG. 4 receiving the signal from the controller rotates the ball screw 48 and reciprocates the linear motion motor 27 and the like along the guide 26 by the screw action of the ball screw 48.

かかる移動は、図１におけるスライダー２９の矢印４９方向への移動であり、かかる往復動におけるその往動時、ラック歯４０に係合する複数の平歯車３９が回転して、弾性ブロック２８と接触する包装体３０を９０度角だけ回転させる。つまり図３において包装体３０は移動中に仮想線３０aの状態に回され、その直後、弾性ブロックは上方に退避しかつ元の位置に復動する。つまりかかる運動は図６における弾性ブロック２８のブロックモーション５０aに相当する。この場合、弾性ブロック２８の復動スピードに比較して往動スピードは緩やかで、かかるスピード差でもって包装体３０を回転させる充分な時間を獲得する。   This movement is the movement of the slider 29 in FIG. 1 in the direction of the arrow 49, and a plurality of spur gears 39 that engage with the rack teeth 40 rotate during the reciprocating movement to contact the elastic block 28. The package 30 to be rotated is rotated by 90 degrees. That is, in FIG. 3, the package 30 is turned to the state of the virtual line 30a during the movement, and immediately after that, the elastic block is retracted upward and moved back to the original position. That is, this motion corresponds to the block motion 50a of the elastic block 28 in FIG. In this case, the forward movement speed is moderate as compared with the backward movement speed of the elastic block 28, and sufficient time for rotating the package 30 is obtained with such a speed difference.

図６に示すように、ロータリカッター２１の後位に配置した２個の弾性ブロック２８でもって、２個の包装体３０を搬送中に回転する場合、２個の弾性ブロック２８はそれぞれ、包装体３０のカットピッチ５０と同じ量５０aだけ前進し、その間に２個の包装体３０をそれぞれ９０度角回転させた後、ブロックモーションで元の位置に復帰した直後、ロータリカッター２１の切断のタイミングに合わせて再び後続の、２個の包装体の上に下降してこれら包装体を搬送かつ回転させる運動を継続するのである。   As shown in FIG. 6, when two packaging bodies 30 are rotated during conveyance with two elastic blocks 28 arranged at the rear of the rotary cutter 21, the two elastic blocks 28 are each a packaging body. Advancing by the same amount 50a as the cut pitch 50 of 30 and rotating the two packaging bodies 30 by 90 degrees in the meantime, immediately after returning to the original position by block motion, at the timing of cutting of the rotary cutter 21 At the same time, the movement of descending onto the subsequent two packages and transporting and rotating these packages is continued.

以上のようにして、図７における第２ベルトコンベヤ２５の上で横向きにした各包装体は、耐圧チャンバー６０を形成する下側の定盤６１を囲繞する第３ベルトコンベヤ６５に移乗する。なおこの場合、第２ベルトコンベヤ２５の回転スピードに比べて、第３ベルトコンベヤ６５の回転スピードは遅く、このスピード差を利用して第２ベルトコンベヤ６５に移乗するそれぞれの包装体３０の間隔を狭めるので、仮に、耐圧チャンバー６０の収容容積を包装体４個分に設定した場合は、その分、耐圧チャンバー６０の容積縮小が可能になるのである。   As described above, each package body placed sideways on the second belt conveyor 25 in FIG. 7 is transferred to the third belt conveyor 65 surrounding the lower surface plate 61 forming the pressure-resistant chamber 60. In this case, the rotation speed of the third belt conveyor 65 is slower than the rotation speed of the second belt conveyor 25, and using this speed difference, the interval between the packaging bodies 30 transferred to the second belt conveyor 65 is set. Therefore, if the accommodation volume of the pressure-resistant chamber 60 is set to four packaging bodies, the volume of the pressure-resistant chamber 60 can be reduced accordingly.

図９に示すように耐圧チャンバー６０は、両側一対のレール６６上にスライド自在に支持した定盤６１と、前記定盤６１に立設した柱状ガイド６３に沿って上下動して該定盤６１の上面に気密に被さる蓋材６２とからなり、またねじ棒６７が係合する前記の定盤６１は、モータ６８を動力とする前記ねじ棒６７の正逆転作用により、蓋材６２を伴って前記レール６６上を設定量だけ往復動する。   As shown in FIG. 9, the pressure chamber 60 moves up and down along a surface plate 61 slidably supported on a pair of rails 66 on both sides and a columnar guide 63 erected on the surface plate 61. The surface plate 61, which covers the upper surface of the screw rod 67 and is engaged with the screw rod 67, is accompanied by the lid member 62 by the forward / reverse action of the screw rod 67 driven by the motor 68. It reciprocates on the rail 66 by a set amount.

図８のごとく定盤６１の上から蓋材６２が下降して内部に４個の包装体を収容した耐圧チャンバー６０は第２ベルトコンベヤ６５と一体に移動し、その後、開放して再び４個の包装体３０を受け入れるために第２ベルトコンベヤ６５の移動とは反対方向に移動する。前記の耐圧チャンバー６０が第２ベルトコンベヤ６５と一体に移動する間、図９においてホース６４を通して耐圧チャンバー６０内の空気を排除したあと、アクチュエータ８０でもってシールバー６９を押し上げ、上部に固定したシール台７０とでもって、包装体３０の両端開口縁を加熱して密封することになるのである。   As shown in FIG. 8, the pressure-resistant chamber 60 in which the lid member 62 descends from the top of the surface plate 61 and accommodates four packages is moved integrally with the second belt conveyor 65, and then opened and again four pieces are opened. In order to receive the package 30, the second belt conveyor 65 moves in the opposite direction. While the pressure-resistant chamber 60 moves integrally with the second belt conveyor 65, after the air in the pressure-resistant chamber 60 is removed through the hose 64 in FIG. 9, the seal bar 69 is pushed up by the actuator 80, and the seal fixed to the upper part. With the base 70, the opening edge of the both ends of the package 30 is heated and sealed.

図４ではピストンロッド３３と、平歯車３９との間に滑りキー３４を備える筒材３５を配置したが、別箇の実施例としては、前記筒材３５を取り除き、ピストンロッド３３にホールベアリング３６を介して直接、平歯車３９を支持する一方、平歯車３９に直接、保護材３７を固定することで、ラック歯４０に対して平歯車３９の歯を直接上下にスライドさせて弾性ブロック２８を上下に操作することが可能である。   In FIG. 4, the tubular member 35 having the sliding key 34 is arranged between the piston rod 33 and the spur gear 39. However, as another embodiment, the tubular member 35 is removed and the piston rod 33 is attached to the hall bearing 36. The spur gear 39 is supported directly via the spur gear 39, and the protective member 37 is fixed directly to the spur gear 39, so that the teeth of the spur gear 39 are slid directly up and down with respect to the rack teeth 40. It is possible to operate up and down.

図１０に示すごとく第２ベルトコンベヤ５０を支える先端のプーリ５１を定盤６１に支持することで、耐圧チャンバー６０の往復動によって、該耐圧チャンバー６０と一体に伸縮する第２ベルトコンベヤ５０を形成する。つまり可動プーリ５２を矢印のごとく耐圧チャンバー６０の往復運度５４と一体に変位させることにより、第２ベルトコンベヤ５０は耐圧チャンバー６０の往復動と一体に伸縮して包装体３０を、箱型の定盤６１内に設置した第２コンベヤの補助ベルト５５に運びいれる。なお前記の補助ベルト５５は、定盤６１が前進５６している時は停止し、前記定盤６１が後退５７するときに回転して第２ベルトコンベヤ５０上の包装体３０を受け入れるのであり、この実施例では補助ベルト５５を含めて第２ベルトコンベヤ５０を形成する。   As shown in FIG. 10, by supporting the pulley 51 at the tip supporting the second belt conveyor 50 on the surface plate 61, the second belt conveyor 50 that expands and contracts integrally with the pressure chamber 60 is formed by the reciprocating motion of the pressure chamber 60. To do. That is, by moving the movable pulley 52 integrally with the reciprocation 54 of the pressure-resistant chamber 60 as shown by the arrow, the second belt conveyor 50 expands and contracts integrally with the reciprocating movement of the pressure-resistant chamber 60, and the package 30 is made to be a box-shaped. It is carried to the auxiliary belt 55 of the second conveyor installed in the surface plate 61. The auxiliary belt 55 stops when the surface plate 61 is moving forward 56 and rotates when the surface plate 61 moves backward 57 to receive the package 30 on the second belt conveyor 50. In this embodiment, the second belt conveyor 50 including the auxiliary belt 55 is formed.

図４に示した構成は、ガイド２６に沿って移動するスライダー３２の運動力で、ラック４０に係合する平歯車３９と一体に弾性ブロック２８を回転するものであったが、図１１に示す実施例は、直動モータ２７を固定したスライダー３２がガイド２６に沿って往復動動する構成に変化はないが、前記直動モータのピストンロッド３３の下端にサーボモータ７５を固定し、このサーボモータ７５の軸に弾性ブロック２８を固定した点が異なる。要するに図１でも説明したが、パルス発生器４４から発信するパルスを受ける制御器４６は、正逆転モータ４７を介してねじ棒４８を操作しスライダー３２を、ガイド２６に沿って一定の区間で往復動させ、また前記制御器４６はサーボモータ７５への信号で弾性ブロック２８を、前記スライダー３２の運動に合わせて９０度角で正逆転するともに、切換弁７６を操作してポンプ７７で直動モータ２７を操作して弾性ブロック２８の上下動を、該弾性ブロック２８の回転に合わせてコントロールするのである。   In the configuration shown in FIG. 4, the elastic block 28 is rotated integrally with the spur gear 39 engaged with the rack 40 by the moving force of the slider 32 moving along the guide 26. In the embodiment, there is no change in the configuration in which the slider 32 to which the linear motion motor 27 is fixed reciprocates along the guide 26. However, a servo motor 75 is fixed to the lower end of the piston rod 33 of the linear motion motor. The difference is that the elastic block 28 is fixed to the shaft of the motor 75. In short, as described with reference to FIG. 1, the controller 46 that receives a pulse transmitted from the pulse generator 44 operates the screw rod 48 via the forward / reverse rotation motor 47 to reciprocate the slider 32 along the guide 26 in a certain section. Further, the controller 46 makes the elastic block 28 forward and reverse at a 90 degree angle in accordance with the movement of the slider 32 by a signal to the servo motor 75 and operates the switching valve 76 to directly move by the pump 77. The motor 27 is operated to control the vertical movement of the elastic block 28 in accordance with the rotation of the elastic block 28.
