Description

本発明は、水平方向に連続的に送り出されるフイルムシートで筒状連続体を形成し、その内部に菓子片等の被包装物を充填した後、充填部の前後を溶断してピロー包装品にする横型の、包装装置に関するものである。   In the present invention, a cylindrical continuous body is formed with a film sheet that is continuously fed out in the horizontal direction, and after filling an article to be packaged such as a confectionery piece inside, the front and back of the filling portion are melted to form a pillow packaged product. This relates to a horizontal type packaging apparatus.

上記包装装置として、従来、特開平8−230809号(特許文献1)に開示されたものが知られている。
図14は、従来の包装装置の平面図であり、図15はその一部切欠きの側面図である。
被包装物(A)の搬送路となる物品滑走板(14)を上下に貫通する移送杆(10)(10)は、無端状のチェーン(15)に所定ピッチで配設されていると共に、該チェーン(15)はスプロケット(1)で駆動されるようになっている。前記スプロケット(1)の上方には、包装シート(12)を巻き取ったロール(11)とフィードローラ(17)(17)が配設されていると共に、フィードローラ(17)(17)から送り出された包装シート(12)は、フォーマたる整形筒(13)に挿通されて筒状連続体(20)に整形されるようになっている。
As the above-described packaging device, a device disclosed in JP-A-8-230809 (Patent Document 1) has been known.
FIG. 14 is a plan view of a conventional packaging device, and FIG. 15 is a side view of a partially cutaway portion thereof.
The transfer rods (10) and (10) that pass vertically through the article slide plate (14), which is the conveyance path for the packaged item (A), are disposed on the endless chain (15) at a predetermined pitch, and The chain (15) is driven by a sprocket (1). Above the sprocket (1), a roll (11) and a feed roller (17) (17) around which a packaging sheet (12) is wound are disposed and fed from the feed roller (17) (17). The package sheet (12) thus formed is inserted into a shaping cylinder (13) as a former and shaped into a cylindrical continuous body (20).

整形筒(13)の下流側には、一対のセンタシールローラ(16)(16)と、エンドシール装置(18)がこの順序で配設されており、エンドシール装置(18)は、上下一対の回転軸(18a)(18a)に突設された挟圧熱板(18b)(18b)を備えている。又、エンドシール装置(18)の更に下流側には、図示しない排出コンベヤが連設されている。   A pair of center seal rollers (16), (16) and an end seal device (18) are arranged in this order on the downstream side of the shaping cylinder (13). There are sandwiched heat plates (18b) and (18b) projecting from the rotary shafts (18a) and (18a). Further, a discharge conveyor (not shown) is continuously provided downstream of the end seal device (18).

このものでは、フィードローラ(17)(17)から送り出された包装シート(12)は、整形筒(13)内を通過することで幅方向に丸められる。これにより、包装シート(12)の両側縁が重なった合掌部(19)が下部から垂下する略Ω状断面の筒状連続体(20)が整形筒(13)から送り出される。   In this case, the packaging sheet (12) sent out from the feed rollers (17) and (17) is rounded in the width direction by passing through the shaping cylinder (13). As a result, the tubular continuous body (20) having a substantially Ω-shaped cross section in which the palm portion (19) where both side edges of the packaging sheet (12) overlap is suspended from the lower portion is sent out from the shaping cylinder (13).

一方、整形筒(13)の入り口部では、チェーン(15)に設けられた移送杆(10)によって、被包装物(A)が筒状連続体(20)内に水平に押し込まれる。そして、整形筒(13)から送り出される筒状連続体(20)の下部に垂下する合掌部(19)(包装シート(12)の両側縁の重なり部)がセンタシールローラ(16)(16)で挟圧・溶着された後、包装単位数(図示例のものでは3個)毎に纏められた被包装物(A)の組の相互間が、エンドシール装置(18)の挟圧熱板(18b)(18b)で挟圧されて溶着されると同時に切断される。これにより、被包装物(A)が包装単位数毎に包装されたピロー包装品(H)が完成し、これが、図示しない排出コンベヤで排出される。   On the other hand, at the entrance of the shaping cylinder (13), the article to be packaged (A) is pushed horizontally into the cylindrical continuous body (20) by the transfer rod (10) provided on the chain (15). And the palm part (19) (the overlapping part of both side edges of the packaging sheet (12)) hanging from the lower part of the cylindrical continuous body (20) delivered from the shaping cylinder (13) is a center seal roller (16) (16) After being clamped and welded at the end of the end seal device (18), the pair of articles to be wrapped (A) grouped by the number of packaging units (three in the example shown in the figure) (18b) (18b) is sandwiched and welded, and simultaneously cut. Thereby, the pillow package product (H) in which the article to be packaged (A) is packaged for each number of packaging units is completed, and this is discharged by a discharge conveyor (not shown).

このものでは、整形筒(13)で整形される筒状連続体(20)の上流端の開放部に被包装物(A)を移送杆(10)で送り込む。従って、下向きに送り出されるフイルムシートで整形された縦長の筒状連続体内に被包装物を自由落下させて充填する縦型ピロー包装機と相違し、図14,図15に示す粒状の被包装物(A)以外に、煎餅等の扁平な被包装物(A)を重ね合わせた状態で包装する場合や、トレー等に充填された被包装物(A)を包装することが出来る。
特開平8−230809号公報
In this case, the article to be packaged (A) is fed by the transfer rod (10) into the open part at the upstream end of the cylindrical continuous body (20) shaped by the shaping cylinder (13). Therefore, unlike the vertical pillow packaging machine in which a package is dropped freely and filled into a vertically long cylindrical continuous body shaped by a film sheet sent downward, the granular package shown in FIGS. In addition to (A), it is possible to wrap a flat article (A) such as rice cracker in a state where it is overlapped, or to wrap an article (A) filled in a tray or the like.
JP-A-8-230809

しかしながら、上記従来の包装装置では、整形筒(13)から送り出された筒状連続体(20)内で被包装物(A)が安定しないことから、包装シート(12)の必要量が多くなり、資源の有効利用が図れないという問題があった。かかる問題点について更に詳述する。   However, in the above-described conventional packaging device, since the article to be packaged (A) is not stable in the cylindrical continuous body (20) fed from the shaping cylinder (13), the required amount of the packaging sheet (12) increases. There was a problem that effective use of resources could not be achieved. This problem will be further described in detail.

上記従来の包装装置は、被包装物(A)を水平に送る構成であるから、整形筒(13)から送り出された筒状連続体(20)内では、被包装物(A)が自由状態にあって安定しない。従って、被包装物(A)(A)の整列状態が崩れて拡散し易く、又、被包装物(A)の組(包装単位数毎に纏められている)の相互間のピッチがずれ易い。その結果、被包装物(A)の組の相互のピッチが小さくなる場合が生じる。よって、かかる状態で、包装単位数毎に纏められた被包装物(A)の組の相互間をエンドシール装置(18)で挟圧すると、被包装物(A)がエンドシール装置(18)の挟圧熱板(18a)(18b)で挟まれて破損したり、これによって生じた破片がエンドシール部に噛み込んで密封性が担保できなくなる。かかる問題を考慮し、上記従来の包装装置では、被包装物(A)の組の相互間のピッチを予め大きく設定することで、包装単位数毎に纏められた被包装物(A)の各組相互の間隔に余裕を持たせ、これにより、エンドシール装置(18)で被包装物(A)が挟まれないようにしている。このことから、必然的にピロー包装品(H)内の空間率が大きくなり、その結果、包装シート(12)の必要量を少なくできず、資源の有効利用が図れないのである。   Since the conventional packaging apparatus is configured to send the article to be packaged (A) horizontally, the article to be packaged (A) is in a free state in the cylindrical continuous body (20) fed from the shaping cylinder (13). It is not stable. Therefore, the alignment state of the objects to be packaged (A) and (A) is easily broken and diffused, and the pitch between the groups of objects to be packaged (A) (collected for each number of packaging units) is easily shifted. . As a result, the mutual pitch of the set of packages (A) may be reduced. Therefore, in this state, when the end seal device (18) clamps between the sets of the packages (A) collected for each number of packaging units, the package (A) becomes the end seal device (18). The sandwiched heat plates (18a) and (18b) are broken and damaged, or the fragments generated thereby are caught in the end seal portion, so that the sealing performance cannot be secured. Considering such a problem, in the conventional packaging device, each of the packages (A) collected for each number of packaging units is set by setting a large pitch between the groups of packages (A) in advance. The space between the sets is provided with a margin so that the object to be packaged (A) is not pinched by the end seal device (18). For this reason, the space ratio in the pillow package (H) is inevitably increased, and as a result, the required amount of the packaging sheet (12) cannot be reduced, and effective use of resources cannot be achieved.

The upper heater elevating frame (71) is moved up and down by the rotation of the crank (78). In this case, the guide rollers (813) (813) of the lower heater lifting frame (81) are travel grooves (711a) (714a) formed in the vertical rails (711) (714) of the upper heater lifting frame (71). Therefore, only the horizontal component of the rotational motion of the lower heater lifting frame (81) in the vertical posture is transmitted to the upper heater lifting frame (71). As a result, as shown in FIG. 12, the lower heater block (80) has the same shape as the circular orbit (P2) (the circular orbit on which the outer peripheral bracket (B) of the rotating disks (821) (823) and (824) moves). ), The upper heater block (70) has a semicircular locus (P1) similar to the cam groove (680) (see FIG. 8) of the cam disk (68) described above (the horizontal width is the circular orbit (P2 ) Along the same size). And in this embodiment, the dimensions of each part are set so that the lower part of the semicircular locus (P1) and the upper part of the circular orbit (P2) partially overlap. The upper heater block (70) presses against the lower heater block (80), and thereby the upper heater block (70) is lifted upward together with the lifting shaft (72) against the urging force of the push spring (76). As a result, the cutting blade (79) enters the concave groove (800) of the lower heater block (80), and the rear end (S2) of the semi-packaged product (S) is welded and simultaneously cut.

The crank arm (51) constituting the crank device (5) is rotatably supported on the fixed surface (65) by the support shaft (63). The cam follower (52) provided at the input end of the crank arm (51) is in contact with the outer peripheral cam portion (530) of the cam disk (53) attached to the drive shaft (83). A horizontal bar (50) is provided at the output end of the crank arm (51). The crank arm (51) is urged toward the cam disk (53) by a tension spring (54). Accordingly, when the cam disk (53) rotates together with the drive shaft (83), the crank arm (51) rotates, and as a result, as shown in FIGS. 1 and 6, the crank arm (51) of the crank device (5) is rotated. ) The horizontal bar (50) at the upper end performs an arc motion in the vertical direction in the vicinity of the lift area of the upper and lower heater blocks (70) and (80).

[先詰め装置(4)とエンドシール装置(6)の連動関係の説明]
次に、先詰め装置(4)とエンドシール装置(6)の連動関係を説明する。
図11,図13に示すように、筒状連続体(20)に於ける菓子片(99)群の充填部の隣接部が、先詰め装置(4)の水平棒(47)(47)で挟持され、この状態で、コンベヤ(41)(41)が走行する。
[Explanation of the interlocking relationship between the pre-packing device (4) and the end seal device (6)]
Next, the interlocking relationship between the pre-packing device (4) and the end seal device (6) will be described.
As shown in FIG. 11 and FIG. 13, the adjacent part of the filling part of the confectionery piece (99) group in the cylindrical continuous body (20) is the horizontal bar (47) (47) of the pre-packing device (4). In this state, the conveyors (41) and (41) run.

図13の(ア)では、筒状連続体(20)の搬送方向の先端に位置する半包装品(S) (先端部(S1)はエンドシール装置(6)で既に溶着されている)の後端部(S2)がエンドシール装置(6)の上下のヒータブロック(70)(80)で挟圧されて溶着・切断される。尚、この状態では、半包装品(S)の下面が、適宜軌道で移動するトレー(T)で受け止められて水平姿勢に保たれ、これにより、上下のヒータブロック(70)(80)による溶着部に皺が生じるのが防がれる。   In (a) of FIG. 13, the semi-wrapped product (S) located at the front end in the transport direction of the cylindrical continuous body (20) (the front end (S1) is already welded by the end seal device (6)). The rear end (S2) is clamped by the upper and lower heater blocks (70) and (80) of the end seal device (6) to be welded and cut. In this state, the lower surface of the semi-packaged product (S) is received by the tray (T) that is appropriately moved on the track and kept in a horizontal posture, so that the upper and lower heater blocks (70) (80) are welded. It is prevented that wrinkles occur in the part.

次に、(イ)に示すように、前記上下のヒータブロック(70)(80)で溶着・切断されて作られたピロー包装品(H)は、シュート(37)から排出コンベヤ(38)に供給される(図1参照)一方、上下のヒータブロック(70)(80)の上流側に新たに出来た半包装品(S)は、コンベヤ(41)(41)の水平棒(47)(47)で挟持された状態で下方に垂れ下がり、これにより、半包装品(S)が先端に向かって低くなる姿勢に維持される。これにより、菓子片(99)群が半包装品(S)内にて先詰めされた状態になる。   Next, as shown in (a), the pillow package (H) made by welding and cutting with the upper and lower heater blocks (70) (80) is transferred from the chute (37) to the discharge conveyor (38). On the other hand, the new semi-wrapped product (S) on the upstream side of the upper and lower heater blocks (70), (80) is supplied to the horizontal bar (47) of the conveyor (41) (41) (see Fig. 1). 47) hangs down in the state of being pinched, and thereby the semi-wrapped product (S) is maintained in a posture of being lowered toward the tip. As a result, the confectionery pieces (99) group is pre-packed in the semi-wrapped product (S).

続いて、(ウ)に示す工程で、先詰め装置(4)が基端軸(49)(図11参照)を支点として上下に揺動回動し、これにより、半包装品(S)内の菓子片(99)群が更に先詰めされる。従って、本実施の形態では、先詰め装置(4)の下流端近傍の下部に設けられたカムフォロア(42)と、これに当接するカム板(59)の組み合わせが、既述発明特定事項たる「振動付与機構」に対応する。   Subsequently, in the step shown in (c), the pre-packing device (4) swings up and down around the base end shaft (49) (see FIG. 11) as a fulcrum. The confectionery pieces (99) are further pre-packed. Therefore, in the present embodiment, the combination of the cam follower (42) provided in the lower portion near the downstream end of the pre-packing device (4) and the cam plate (59) in contact with the cam follower (59) is a specific matter of the invention described above. Corresponds to “vibration applying mechanism”.

その後、(エ)〜(オ)及び図11に示すように、鉛直姿勢を保って回転する下ヒータブロック(80)と半包装品(S)の干渉を回避するため、クランク装置(5)が作動し、その先端の水平バー(50)が、下ヒータブロック(80)の上方域に於いて、円弧状の軌跡で斜め上方に移動する。これにより、半包装品(S)(先詰め装置(4)の下流端に突出した切断対象部)が持ち上げられ、持ち上げられた半包装品(S)の下方空間にて下ヒータブロック(80)が上昇する((オ)及び図11参照)。   After that, as shown in (d) to (e) and FIG. 11, in order to avoid interference between the lower heater block (80) rotating in a vertical posture and the semi-packaged product (S), the crank device (5) In operation, the horizontal bar (50) at the tip of the bar moves diagonally upward along an arc-shaped locus in the upper area of the lower heater block (80). As a result, the semi-wrapped product (S) (the cutting target projecting at the downstream end of the pre-packing device (4)) is lifted, and the lower heater block (80) in the lower space of the lifted semi-packaged product (S) Rises (see (e) and FIG. 11).

次に、(カ)〜(ク)に示すように、クランク装置(5)の水平バー(50)で持ち上げられた半包装品(S)の下面が適宜軌道で移動するトレー(T)に受け渡されて水平姿勢になり、この水平姿勢になったときに、(ア)の工程に戻って上ヒータブロック(70)と下ヒータブロック(80)が合致する。これにより、半包装品(S)の後端(S2)が溶着されると同時に切断され、この動作の繰り返しによって作られたピロー包装品(H)が、図1のようにシュート(37)から排出コンベヤ(38)に供給される。尚、(カ)の工程では、半包装品(S)の下面にトレー(T)が当接する一方、クランク装置(5)の水平バー(50)が半包装品(S)から離反する。又、(ク)の工程では、上下のヒータブロック(70)(80)が半包装品(S)の後端(S2)を挟む前に、コンベヤ(41)(41)の上流端の水平棒(47)(47)が筒状連続体(20)を上下に挟む。   Next, as shown in (f) to (c), the lower surface of the semi-packaged product (S) lifted by the horizontal bar (50) of the crank device (5) is received by the tray (T) that is appropriately moved on the track. When the horizontal posture is passed, the upper heater block (70) and the lower heater block (80) are matched by returning to the step (a). Thereby, the rear end (S2) of the half-wrapped product (S) is welded and cut at the same time, and the pillow product (H) made by repeating this operation is removed from the chute (37) as shown in FIG. Supplied to the discharge conveyor (38). In the step (f), the tray (T) contacts the lower surface of the semi-wrapped product (S), while the horizontal bar (50) of the crank device (5) separates from the semi-wrapped product (S). In the process (c), before the upper and lower heater blocks (70) (80) sandwich the rear end (S2) of the semi-packaged product (S), the horizontal bar at the upstream end of the conveyor (41) (41). (47) and (47) sandwich the cylindrical continuous body (20) up and down.

以上説明したように、本実施の形態に係る包装装置によれば、図11に示すように、筒状連続体(20)の搬送方向の先端に位置する切断対象部たる半包装品(S)がコンベヤ(41)(41)の水平棒(47)(47)で挟持された状態で下方に垂れ下がり、これにより、菓子片(99)群が半包装品(S)内にて先詰めされた状態になる。従って、包装単位数毎に纏められた菓子片(99)群間のピッチを、予め大きく設定して余裕を持たせなくても、エンドシール装置(6)による挟圧部に被包装物(A)が噛み込む心配が少ない。よって、ピロー包装品(H)内の空間率が少なくなってタイト包装状態になるから、包装シート(12)の必要量が少なくなる。
尚、上記実施の形態では、筒状連続体(20)の先端の半包装品(S)を、先詰め装置(4)のコンベヤ(41)(41)に設けた水平棒(47)(47)で上下から挟むようにしたが、上方のコンベヤ(41)は必須でない。少なくとも下方のコンベヤ(41)が設けられていれば、半包装品(S)の後端(S2)を下方から支持して半包装品(S)を前傾姿勢にできれば、菓子片(99)が先詰めた状態になり、タイト包装が可能になって包装シート(12)の必要量が少なくなるからである。
As described above, according to the packaging device according to the present embodiment, as shown in FIG. 11, the semi-wrapped product (S) that is the cutting target portion located at the front end in the transport direction of the cylindrical continuous body (20). Hangs downward while being sandwiched between the horizontal bars (47) and (47) of the conveyor (41) and (41), so that the confectionery pieces (99) are pre-packed in the semi-wrapped product (S). It becomes a state. Therefore, even if the pitch between the confectionery pieces (99) grouped for each number of packaging units is set large in advance and does not have a margin, the object to be packaged (A ) Is less worried. Accordingly, since the space ratio in the pillow packaged product (H) is reduced and the tightly packed state is obtained, the required amount of the packaging sheet (12) is reduced.
In the above embodiment, the semi-wrapped product (S) at the tip of the cylindrical continuous body (20) is attached to the horizontal bars (47) (47) provided on the conveyors (41) (41) of the pre-packing device (4). ), But the upper conveyor (41) is not essential. If at least the lower conveyor (41) is provided, the rear end (S2) of the half-wrapped product (S) is supported from below and the half-wrapped product (S) can be placed in a forward tilted posture. This is because the package becomes pre-packed, tight packaging becomes possible, and the required amount of the packaging sheet (12) is reduced.

又、コンベヤ(41)(41)の水平棒(47)(47)で挟持されて下方に垂れ下がった状態にある半包装品(S)の後端(S2)を、水平方向又は斜め上下方向に接離する一対のヒータブロックで挟圧し、これにより、溶着・切断してもよい。   In addition, the rear end (S2) of the semi-packaged product (S) that is sandwiched between the horizontal bars (47) and (47) of the conveyor (41) and (41) and hangs downward is placed horizontally or diagonally up and down. The pair of heater blocks that come in contact with and separate from each other may be clamped, whereby welding and cutting may be performed.
