Description

本発明は、横形製袋充填機において物品をフィルムに向けて供給する供給コンベヤに関するものである。   The present invention relates to a supply conveyor for supplying articles toward a film in a horizontal bag making and filling machine.

横形製袋充填機は、製袋手段により筒状に成形された筒状フィルムに向けて物品を所定間隔毎に搬送する供給コンベヤを備えている。この供給コンベヤは、搬送方向の前後に離間するスプロケットに巻掛けた無端チェンに、物品を押送する押送部材を所定間隔毎に配設した搬送体を備えている。包装品種の変更等によって長さ寸法が異なる物品を包装する場合には、搬送体における無端チェンに対する押送部材の配設間隔の変更を要する際には、搬送体が所望の配設間隔となった搬送体と交換するようにしている。また、供給コンベヤが物品と直接接触する箇所であるため、殊に食品等の包装に関しては、衛生上の観点から食品が直に接する供給コンベヤは衛生的な状態を維持することが求められており、コンベヤの枠体その他の構造物を含め、必要に応じてコンベヤから搬送体を取り外す等して、コンベヤ全体をアルコールや水等による洗浄、清掃作業が行なわれている。   The horizontal bag making and filling machine includes a supply conveyor that conveys articles at predetermined intervals toward a cylindrical film formed into a cylindrical shape by bag making means. This supply conveyor is provided with a transport body in which push members for pushing articles are arranged at predetermined intervals on an endless chain wound around a sprocket that is separated in the front and rear directions in the transport direction. When packaging articles with different length dimensions due to changes in packaging varieties, etc., when it is necessary to change the arrangement interval of the pusher member with respect to the endless chain in the conveyance body, the conveyance body has the desired arrangement interval. It is exchanged with the carrier. In addition, since the supply conveyor is in direct contact with the article, especially for packaging of food, etc., the supply conveyor with which food is in direct contact is required to maintain a sanitary condition from the viewpoint of hygiene. The entire conveyor, including the frame of the conveyor and other structures, is removed from the conveyor as necessary, and the entire conveyor is cleaned and cleaned with alcohol, water, or the like.

前述した搬送体の交換や清掃等の保守作業において、供給コンベヤから搬送体を取り外す際には、前記スプロケットに巻掛けられている搬送体の無端チェンを分断して行なうのが一般的である。しかし、無端チェンの脱着作業は手間が掛かることから、これら問題に対応するものとして、例えば特許文献１に開示の装置が提案されている。この装置では、無端チェンが巻掛けられる一方のスプロケットをエアシリンダの作動によって他方のスプロケットに近接するように移動して無端チェンを弛ませると共に、無端チェンを下方から支持するチェーンレールを下降して無端チェンから離間することで、無端チェンを分断することなく装置から側方に取り外し得るよう構成されている。   In the maintenance work such as the replacement and cleaning of the transport body described above, when the transport body is removed from the supply conveyor, it is generally performed by dividing the endless chain of the transport body wound around the sprocket. However, since the work of attaching and detaching the endless chain takes time, an apparatus disclosed in, for example, Patent Document 1 has been proposed to deal with these problems. In this device, one sprocket around which an endless chain is wound is moved closer to the other sprocket by the operation of the air cylinder to loosen the endless chain, and the chain rail that supports the endless chain from below is lowered. By being separated from the endless chain, the endless chain can be removed from the apparatus laterally without being divided.

特開２００９−２０３０５６号公報JP 2009-203056 A

特許文献１に開示の装置では、無端チェンを弛ませる機構にエアシリンダを用いると共に、無端チェンを支持するチェーンレールを昇降させる機構を採用する等により比較的構成が複雑であり、製造コストが嵩む難点がある。また、物品の搬送面を構成する上板や無端チェンの側方を覆うカバーを、無端チェンの脱着に際してコンベヤの機枠から脱着する作業が必要となり、保守作業に手間が掛かる問題も指摘される。   In the apparatus disclosed in Patent Document 1, the structure is relatively complicated by using an air cylinder as a mechanism for loosening an endless chain and a mechanism for raising and lowering a chain rail that supports the endless chain, and the manufacturing cost increases. There are difficulties. Also, it is pointed out that maintenance work is troublesome because it is necessary to detach the cover that covers the side of the end plate and the upper plate constituting the article conveying surface from the conveyor frame when detaching the endless chain. .

本発明は、簡単な構成で、搬送体を脱着する際やコンベヤ清掃時等の保守作業性の改善を図り得る横形製袋充填機の供給コンベヤを提供することを目的とする。   SUMMARY OF THE INVENTION An object of the present invention is to provide a supply conveyor for a horizontal bag making and filling machine that can improve maintenance workability with a simple configuration, for example, when a carrier is detached and when the conveyor is cleaned.

前記ヒンジ２０,７０,７４を介して本体部１０に回動自在に配設される供給ベッド１２と前側面カバー６８と端部カバー７２との夫々、およびガイド調節機構５０に回動自在に配設される物品ガイド４６とは、閉成位置に対して９０度以上回動した開放位置でその開放状態を維持し得るよう構成される。すなわち、包装機の操作側であって搬送体１４の取り外し側となる手前側に位置する前供給ベッド１２および前物品ガイド４６においては、閉成位置において各部材１２,４６における供給コンベヤの表側に臨む表面が、開放位置において前記搬送体１４を脱着する際に前側壁１８の上部空間を移動する無端チェン２２に面することがない姿勢になると共に、前記前側面カバー６８においては、前記閉成位置において表面となる面が、開放位置で静止した姿勢において搬送体１４を脱着する際に前側壁１８の下部空間から外側方へ移動する無端チェン２２に面することがない姿勢となる。これにより、該無端チェン２２が前供給ベッド１２と前物品ガイド４６と前側面カバー６８との夫々の表面に接触して、該チェン２２の汚れが前供給ベッド１２と前物品ガイド４６と前側面カバー６８との表面に付着してしまうようなことがない。また前物品ガイド４６は、図４に示す如く、開放位置で静止した姿勢において前側壁１８の上下寸法内に収まるようになっている。   The supply bed 12, the front side cover 68, and the end cover 72 that are rotatably disposed on the main body 10 through the hinges 20, 70, and 74, and the guide adjustment mechanism 50 are rotatably disposed. The provided article guide 46 is configured to be able to maintain the open state at the open position rotated 90 degrees or more with respect to the closed position. That is, in the front supply bed 12 and the front article guide 46 that are located on the operation side of the packaging machine and on the front side that is the removal side of the transport body 14, on the front side of the supply conveyor in each member 12, 46 in the closed position. The facing surface does not face the endless chain 22 that moves in the upper space of the front side wall 18 when the transport body 14 is detached in the open position, and the front side cover 68 is closed. The surface which is the surface at the position is such that it does not face the endless chain 22 which moves outward from the lower space of the front side wall 18 when the transport body 14 is detached in the posture stationary at the open position. As a result, the endless chain 22 comes into contact with the respective surfaces of the front supply bed 12, the front article guide 46, and the front side cover 68, and dirt on the chain 22 is contaminated by the front supply bed 12, the front article guide 46, and the front side surface. There is no possibility of adhering to the surface with the cover 68. Further, as shown in FIG. 4, the front article guide 46 is adapted to fit within the vertical dimension of the front side wall 18 in a posture that is stationary at the open position.

前記本体部１０における各側壁１６,１８の内側には、前記搬送体１４が上方の走行領域を走行する際に各押送部材３４の通過を検出可能な光電センサ等からなる検出手段７６が配設されており、供給コンベヤにおいて搬送体１４を走行した際に押送部材３４を検出手段７６で検出して得た信号を搬送体の原点位置信号として記憶し、該原点信号によって包装機におけるフィルム送り機構やエンドシール機構等の同期位相合わせ制御を適正にし得る。   On the inner side of the side walls 16 and 18 in the main body 10, a detection means 76 including a photoelectric sensor or the like that can detect the passage of each pusher member 34 when the carrier 14 travels in the upper travel region is disposed. The signal obtained by detecting the pushing member 34 by the detecting means 76 when the conveying member 14 travels on the supply conveyor is stored as an origin position signal of the conveying member, and the film feeding mechanism in the packaging machine is based on the origin signal. Synchronous phase matching control such as an end seal mechanism can be made appropriate.

〔実施例の作用〕
次に、前述した実施例に係る横形製袋充填機の供給コンベヤの作用につき説明する。 (Effects of Example)
Next, the operation of the supply conveyor of the horizontal bag making and filling machine according to the above-described embodiment will be described.

前記搬送体１４を本体部１０から取り外す場合は、図６に二点鎖線で示す如く、前記端部カバー７２を持ち上げてヒンジ７４を中心として上方に向けて回動して奥側の開放位置に臨ませることで、搬送体１４の上流転向部となる第１従動スプロケット２８の上方と手前側および上流側の各開放部Ｔ3,Ｔ1,Ｔ4が一度に開放される。また、前記物品ガイド４６および供給ベッド１２を夫々ヒンジ６４,２０を中心として奥側または手前側に向けて回動して開放位置に臨ませることで、本体部１０の上流端から下流端までの全ての上方開放部Ｔ3が開放される。更に、手前側の前側面カバー６８をヒンジ７０を中心として下端部を手前側に持ち上げるように上方へ回動して開放位置に臨ませることで、前側壁１８の下側の下側開放部Ｔ2が開放される(図４参照)。 When the transport body 14 is removed from the main body 10, as shown by a two-dot chain line in FIG. 6, the end cover 72 is lifted and rotated upward about the hinge 74 to the open position on the back side. By making it face, the open portions T 3 , T 1 , T 4 on the upper side, the near side, and the upstream side of the first driven sprocket 28 that becomes the upstream turning portion of the transport body 14 are opened at a time. Further, the article guide 46 and the supply bed 12 are rotated toward the back side or the near side around the hinges 64 and 20, respectively, so that the article guide 46 and the supply bed 12 face the open position. all of the upper opening portion T 3 is opened. Further, the front side cover 68 on the front side is rotated upward so that the lower end portion is lifted toward the front side with the hinge 70 as the center, and is brought into the open position, so that the lower side open portion T on the lower side of the front side wall 18 is reached. 2 is opened (see FIG. 4).

次いで、前記操作ハンドル４４を回転操作して調節手段２６を作動することで第１従動スプロケット２８を下流側に移動して、無端チェン２２を取り外し得る状態まで十分に弛ませる。そして、該無端チェン２２を上流転向部と下流転向部との各スプロケット２８,３０,３２の歯部から外して手側前に移動させ、そのまま本体部１０の開放状態の上方開放部Ｔ3、下側開放部Ｔ2、側方開放部Ｔ1を経て本体部１０より手前側に取り外すことができる。 Next, by rotating the operation handle 44 and operating the adjusting means 26, the first driven sprocket 28 is moved downstream to sufficiently loosen the endless chain 22 until it can be removed. Then, the endless chain 22 is removed from the tooth portions of the sprockets 28, 30, 32 of the upstream turning portion and the downstream turning portion and moved to the front side, and the upper opening portion T 3 in the opened state of the main body portion 10 is left as it is. It can be removed from the main body 10 to the near side through the lower opening T 2 and the side opening T 1 .

なお、手前側の前側面カバー６８は、任意の開放角度位置で静止した状態を維持し得るので、搬送体１４の脱着に際して作業者は前側面カバー６８を開放位置に支え持ちながら作業を行なう必要はなく、作業負荷を軽減することができる。   Note that the front side cover 68 on the front side can be kept stationary at an arbitrary opening angle position, so that the operator needs to work while holding the front side cover 68 in the open position when the transport body 14 is detached. No, the workload can be reduced.

前述したように、前記調節手段２６により無端チェン２２を弛ませると共に、前記供給ベッド１２と物品ガイド４６と前側面カバー６８および端部カバー７２を回動して各開放部Ｔ3,Ｔ2,Ｔ1を開放することで搬送体１４を脱着することができるので、動力源を設ける等の複雑な構成を採用することなく、供給コンベヤの清掃や搬送体１４の脱着に係る作業は工具を使用することなく全て作業者の手作業で行ない得る簡単な構成とすることができる。また、各開放部Ｔ3,Ｔ2,Ｔ1を開閉するコンベヤのカバー類並びに物品ガイド等の供給ベッド１２と物品ガイド４６と前側面カバー６８および端部カバー７２を本体部等に回動自在に支持したから、搬送体１４の脱着やカバー類の内面側の清掃に際して該供給ベッド１２と物品ガイド４６と前側面カバー６８および端部カバー７２を本体部等から取り外したり取り付ける等の手間がなく作業負荷を軽減できる。 As described above, the endless chain 22 is loosened by the adjusting means 26, and the supply bed 12, the article guide 46, the front side cover 68, and the end cover 72 are rotated to open the open portions T 3 , T 2 ,. it is possible to desorb the carrier 14 by opening the T 1, without employing a complicated configuration, such as providing the power source, the working of the desorption cleaning or carrier 14 of the feed conveyor of a tool It can be set as the simple structure which can be performed by an operator's manual operation without doing all. Further, the conveyor covers for opening and closing each of the open portions T 3 , T 2 , T 1 , the supply bed 12 for the article guide, the article guide 46, the front side cover 68, and the end cover 72 can be rotated to the main body. Therefore, there is no need to remove or attach the supply bed 12, the article guide 46, the front side cover 68, and the end cover 72 from the main body or the like when the transport body 14 is detached or the inner surface of the covers is cleaned. The workload can be reduced.

前記調節手段２６は、ハンドル４４を、本体部１０の上流端より外側に突出した位置で操作し得るから操作性がよく、しかも該操作ハンドル４４は、無端チェン２２が第１従動スプロケット２８へ巻き掛けられる上流転向部より奥側に位置しているから、搬送体１４を手前側から脱着するに際して妨げとなって脱着作業に手間取ることはない。   The adjusting means 26 can operate the handle 44 at a position protruding outward from the upstream end of the main body 10, so that the operation handle 44 has good operability, and the endless chain 22 is wound around the first driven sprocket 28. Since it is located on the back side from the upstream turning portion to be hung, it becomes a hindrance when detaching the transport body 14 from the front side, so that it does not take time for the detachment work.

前記搬送体１４の脱着に際し、手前側に位置する前供給ベッド１２と前物品ガイド４６および前側面カバー６８は、閉成位置から９０度以上回動した開放位置において何れの表面も脱着する無端チェン２２に面しない姿勢となる。すなわち、閉成位置において前側壁１８の上側に位置する前供給ベッド１２および前物品ガイド４６では、開放位置において各表面が下方を向くことで内面が無端チェン２２の脱着時にチェンと面し、閉成位置において前側壁１８の下側に位置する前側面カバー６８では、開放位置において表面が上方を向くことで内面が無端チェン２２の脱着時にチェンと面し、これら前供給ベッド１２と前物品ガイド４６および前側面カバー６８の上下空間を移動する無端チェン２２が接触したとしても、該チェン２２の油分等が前供給ベッド１２と前物品ガイド４６および前側面カバー６８の表面に付着してしまう問題が生ずるのを防止し得るものである。また、閉成位置において内面となる内側を開放時に表側に向けた状態にすることができるので、これら供給ベッド１２と物品ガイド４６および前側面カバー６８の内面の清掃作業において供給コンベヤの本体部１０から取り外す必要がなく、作業負荷軽減と保守作業の迅速化をなし得る。   When the transport body 14 is detached, the front supply bed 12, the front article guide 46 and the front side cover 68 located on the front side of the transport body 14 are endless chains in which any surface is detached at an open position rotated 90 degrees or more from the closed position. The posture does not face 22. That is, in the front supply bed 12 and the front article guide 46 positioned on the upper side of the front side wall 18 in the closed position, each surface faces downward in the open position, so that the inner surface faces the chain when the endless chain 22 is detached and closed. In the front side cover 68 positioned below the front side wall 18 in the formation position, the inner surface faces the chain when the endless chain 22 is attached / detached because the surface faces upward in the open position, and the front supply bed 12 and the front article guide. Even when the endless chain 22 moving in the vertical space of the front and rear side covers 68 and the front side cover 68 comes into contact, the oil content of the chain 22 adheres to the front supply bed 12, the front article guide 46, and the front side cover 68. Can be prevented. Further, since the inner side which is the inner surface in the closed position can be set to the front side when opened, the main body portion 10 of the supply conveyor in the cleaning operation of the inner surfaces of the supply bed 12, the article guide 46 and the front side cover 68. There is no need to remove it from the machine, reducing the workload and speeding up the maintenance work.

清掃等の保守が完了した前記搬送体１４をスプロケット群に巻掛けた後は、取り外し時とは逆に、前記操作ハンドル４４の回転操作によって無端チェン２２を張ると共に、供給ベッド１２と物品ガイド４６と前側面カバー６８および端部カバー７２の夫々を閉成位置まで回動することで運転が可能な状態となる。   After the transport body 14 that has undergone maintenance such as cleaning is wound around the sprocket group, the endless chain 22 is stretched by rotating the operation handle 44, and the supply bed 12 and the article guide 46 are reversed. Then, the front side cover 68 and the end cover 72 are turned to the closed position to enable operation.

前記運転可能な状態で前記搬送体１４を走行させることで、前記押送部材３４を検出手段７６で検出して得た信号が搬送体１４の原点位置信号として記憶され、該原点信号によって包装機におけるフィルム送り機構やエンドシール機構等の各作動機構と供給コンベヤとの同期位相合わせ制御が行なわれる。すなわち、搬送体１４を脱着する度に同期位相合わせのため、予め定められた位置に押送部材３４を位置決めして同期位相合わせを行なう等の作業が不要となり、熟練者でなくても保守後の運転再開までの操作に簡単に対処し得る。   By running the transport body 14 in the operable state, a signal obtained by detecting the pushing member 34 by the detecting means 76 is stored as an origin position signal of the transport body 14, and the origin signal is used in the packaging machine. Synchronous phase matching control between each operation mechanism such as a film feed mechanism and an end seal mechanism and the supply conveyor is performed. That is, every time the carrier 14 is detached or attached, synchronization phase alignment is performed, so that operations such as positioning the pushing member 34 at a predetermined position and performing synchronization phase alignment are unnecessary. It is possible to easily deal with operations up to restarting operation.

(1) In the embodiment, the case of the transport body 14 using the endless chain 22 has been described. However, other endless cords such as a toothed belt can be used, and the rotation is wound according to the endless cord to be used. A body (such as a toothed pulley) may be used.
(2) In the embodiment, each of the supply bed 12, the article guide 46, the front side cover 68 and the end cover 72 that opens and closes the open portions T 3 , T 2 , T 1 of the main body 10 is rotated to the main body 10. Although supported freely, it is possible to adopt a configuration in which the respective members 12, 46, 68, 72 are slidably disposed and the corresponding opening portions T 3 , T 2 , T 1 are opened and closed by sliding movement.
(3) the end cover 72 in the embodiment, integrally a top panel 72a and the side panels 72b and end panels 72c for opening and closing the upper opening portion T 3 and the side opening T 1 and the upstream opening portion T 4 of the main body portion 10 As described in the case of the formation, a configuration in which each panel 72a, 72b, 72c is independently movably disposed on the main body portion 10 and the corresponding opening portions T 3 , T 1 , T 4 are individually opened and closed. Can be adopted. Also, the end face panel 72c can adopt a form so as not to opened and closed by fixed disposed on the main body side separately from the end cover 72, the upper opening T 3 of at least the upstream turning portion and the side a square opening T 1 may be constituted to be opened and closed.
(4) In the embodiment, the adjusting means 26 has been described as a means for adjusting the tension of the endless chain 22. However, when the transport body 14 is detached, the first driven sprocket 28 is moved separately from the tension adjustment to move the endless chain. Various configurations that allow the chain 22 to relax may be employed. In this case, the adjusting means 26 switches the first driven sprocket 28 between the first position where the endless chain 22 is stretched with the other sprockets 30 and 32 and the second position where the endless chain 22 is loosened. By configuring, it is possible to easily return to the original tension without performing tension adjustment after maintenance work.
(5) In the embodiment, the mechanism using the pair of adjusting shafts 36 and 38 is adopted as the adjusting means 26. However, the present invention is not limited to this configuration, and various forward / backward moving mechanisms can be adopted. Further, the operation handle 44 that operates the adjusting means 26 employs a configuration that is disposed, for example, inside the end cover 72 at the upstream end of the main body 10 and at an upstream position from the upstream turning portion when the transport body 14 is attached / detached.
