Abstract

PROBLEM TO BE SOLVED: To mechanize an operation securely stacking articles to be conveyed to make them in a stacked state and accumulating the same in good order at a predetermined position, wherein the article to be conveyed are "noshi envelopes" or others having swelling in a thickness direction and uneven thicknesses caused by having folded back pieces, and thereby to make it possible mechanize an operation for filling the bags.SOLUTION: An accumulating device has a conveying in means 17 repeating to convey the articles W to be conveyed to an accumulating preparing position 16 one by one, a raising means 19 raising the articles W to be conveyed and forming a conveying in space S of the article W to be conveyed brought in next time to the accumulation preparing position 16 whenever the articles W to be conveyed are conveyed into the accumulation preparing position 16, and a levelling means 18 making the body pieces b and the folded back pieces f of the articles W to be conveyed abut on each other in an overlaying shape by pushing the upper surface of the article W to be conveyed which is a first one in an accumulation unit raised to the accumulation preparation position 16.

Description

本発明は、折返し片を有する搬送物の集積装置に関するものである。   The present invention relates to an apparatus for stacking conveyed items having folded pieces.

図7に示すように、紙を折り畳んで「のし袋」等として使用する袋Wでは、長方形状をした袋本体bの上下両短辺部から裏側に向けて一対の折返し片fが生じるようになっているが、これらの折返し片fは袋本体bに対する折り癖が弱く、元の平坦な角度に戻ろうとする力が残っている。そのため、この種の袋Wは、厚み方向(t寸法参照)に膨らみを有したものとなっている。   As shown in FIG. 7, in a bag W that is used as a “sheet bag” by folding paper, a pair of folded pieces f are formed from the upper and lower short sides of the rectangular bag body b toward the back side. However, these folded pieces f have weak folds with respect to the bag body b, and a force for returning to the original flat angle remains. Therefore, this type of bag W has a bulge in the thickness direction (see t dimension).

ところで、この種の袋Wは、複数枚(例えば10枚)をセットにして樹脂フィルム製の包装袋へ袋詰めした状態で販売することがある。従来、この袋詰めをするための作業は、各袋Wに厚み方向の膨らみがあり、且つ、厚さtが一定しないこと等が要因となり、手作業で行わざるを得ないものであった。
なお、この種の袋Wとは異なり、厚みが薄い物品や厚みが一定の物品を袋詰めする場合、或いは単一の物品を個別に袋詰めする場合であれば、前記したような袋詰め作業を機械化することは実現されている。例えば、特許文献1には、包装袋の素材(フィルム)を巻いた原反からフィルムを帯状に巻き出し、フィルムの帯幅を略半減させるように二つ折りしながら、フィルムの巻き出し方向に沿って接着剤の塗布(袋蓋封止用の糊部を形成)、及び溶断(袋幅に合わせた切断と同時に袋幅に相当する側縁の溶着)を行い、その後に、袋口の開口、袋内への物品の押し込み、袋蓋の封止、をこの順番で行う装置が提案されている。
By the way, this kind of bag W may be sold in a state in which a plurality of bags (for example, 10 sheets) are packed into a packaging bag made of a resin film. Conventionally, this bag filling operation has to be performed manually because each bag W has a bulge in the thickness direction and the thickness t is not constant.
In addition, unlike this type of bag W, when packing an article having a small thickness or an article having a constant thickness, or when packing a single article individually, the bagging operation as described above is performed. Has been realized. For example, in Patent Document 1, a film is unwound in a belt shape from a raw material wound with a packaging bag material (film), and folded in half so as to substantially halve the width of the film, along the film unwinding direction. Application of adhesive (forms a glue part for sealing the bag lid) and fusing (welding the side edges corresponding to the bag width simultaneously with cutting according to the bag width), and then opening the bag mouth, There has been proposed an apparatus for pushing an article into a bag and sealing a bag lid in this order.

特許第4342089号公報Japanese Patent No. 4342089

前記したように、厚み方向に膨らみがあり、且つ、厚さtが一定しない「のし袋」等の袋Wを、しかも複数枚をセットにして袋詰めする作業は、手作業で行わなければならなかったため、非効率的であり、またコストダウンの妨げとなっていた。殊に、包装袋の製袋工程と袋詰め作業とを別々で行うことになるため、途中に荷造りや輸送作業、荷ほどき等の作業が必要になる等の問題も生起していた。   As described above, the operation of packing a plurality of bags W such as “pouch bags” that are bulging in the thickness direction and whose thickness t is not constant must be performed manually. Therefore, it is inefficient and hinders cost reduction. In particular, since the packaging bag making process and the bag filling operation are performed separately, problems such as packing, transportation work, unpacking work, etc. have occurred.

そこで、この袋詰め作業の機械化が希求されるところとなっていたが、この種の袋Wについては、そもそも袋詰め位置まで搬送して位置決め停止させること自体、非常に困難であるばかりか、所定枚数を確実に計数しつつ段積み状態にし、整然と集積することは更に困難なものとされていた。それ故、袋詰め作業の機械化は実質的に不可能か、又は可能であったとしても装置構成が複雑となって実現が難しいとされていた。   Therefore, mechanization of this bagging work has been demanded. However, for this type of bag W, it is not only difficult to transport to the bagging position and stop positioning itself, It was made more difficult to orderly stack the sheets while counting them reliably. Therefore, mechanization of the bagging operation is practically impossible, or even if possible, the apparatus configuration is complicated and difficult to realize.

なぜなら、前記袋Wでは、折返し片fが袋本体bに対して元の平坦な角度に戻ろうとするため、一枚ごとに厚さtが一定せず、しかも載置安定性に欠けたものとなっている(複数枚の袋Wを段積みすれば当然に不安定さも積算される)ことが大きなネックとなるからであった。
本発明は、上記事情に鑑みてなされたものであって、折返し片を有することが原因で厚み方向に膨らみがあり、且つ、厚みが一定しない「のし袋」等を搬送物として、この搬送物を所定位置にて確実に積み重ねて段積み状態にし、整然と集積する作業を機械化できるものとし、もって、袋詰めなどの作業の機械化をも実現させることができる、折返し片を有する搬送物の集積装置を提供することを目的とする。
Because, in the bag W, the folded piece f tries to return to the original flat angle with respect to the bag body b, so that the thickness t is not constant for each sheet and the mounting stability is lacking. This is because it becomes a big bottleneck (if a plurality of bags W are stacked, naturally instability is also integrated).
The present invention has been made in view of the above circumstances, and has a swell in the thickness direction due to the presence of the folded piece, and a “pouch bag” or the like whose thickness is not constant is used as a transported object. A stacking device for transported objects having folded pieces, which can be mechanized by stacking and stacking in a predetermined position, and mechanizing the work of orderly stacking, and also realizing mechanization of work such as bagging. The purpose is to provide.

前記目的を達成するために、本発明は次の手段を講じた。
即ち、本発明に係る折返し片を有する搬送物の集積装置は、扁平な本体片の表側又は裏側に折返し片が設けられた搬送物を1枚ずつ集積準備位置へ搬送することを繰り返す搬入
手段と、前記搬入手段により集積準備位置に搬送物が搬入されるたびに当該搬送物を上昇させて集積準備位置に対して次ぎに搬入される搬送物の搬入スペースを形成させる持ち上げ手段と、前記持ち上げ手段により集積準備位置上へ上昇させられた集積単位で最初となる搬送物に対してその上面を下方へ押圧することで当該搬送物の本体片と折返し片とを重合状に当接させる均し手段と、を有していることを特徴とする。
In order to achieve the above object, the present invention has taken the following measures.
That is, the transported article stacking apparatus having folded pieces according to the present invention includes a carrying-in means for repeatedly transporting the transported articles provided with the folded pieces on the front side or the back side of the flat main body piece one by one to the stacking preparation position. A lifting means that raises the transported object each time the transported object is transported to the stacking preparation position by the transporting means to form a transporting space for the transported object to be transported next to the stacking preparation position; and the lifting means Leveling means that presses the upper surface of the first transported unit in the stacking unit that has been raised to the stacking preparation position by the downward movement so that the main body piece and the folded piece of the transported product come into contact in a superposed manner. It is characterized by having.

このように集積装置として均し手段を具備した構成にすることで、集積しようとする搬送物や、集積中の搬送物、或いは集積後の搬送物を、折返し片と本体片とが重合状に当接する状態に保持させることができる。すなわち、搬送物を折返し片をも含めて扁平に整形できるので、搬送物の厚さを一定させ、載置安定性を高めることができる。そのため、搬送物を集積準備位置にて段積み状態で整然と集積させることが可能となる。このような集積装置を用いれば、集積した複数の搬送物を後の工程で袋詰めすることも機械化できるようになる。   In this way, the stacking device is provided with a leveling means, so that the folded piece and the main body piece of the transported object to be stacked, the transported object during stacking, or the transported object after stacking are polymerized. It can be held in contact. That is, since the conveyed product can be shaped flat including the folded piece, the thickness of the conveyed product can be made constant and the mounting stability can be improved. Therefore, it becomes possible to stack the transported items neatly in a stacked state at the stacking preparation position. By using such a stacking apparatus, it is possible to mechanize packing a plurality of transported articles in a subsequent process.

前記均し手段は、集積準備位置の側部で長手方向を縦方向に向けて設けられた縦ガイドと、この縦ガイドに沿って上下動自在に設けられた昇降部材と、この昇降部材に設けられて集積準備位置に搬入された搬送物の上面へ向けて突出する押圧状態と搬送物から離反する退避状態とに切替動作する押圧部材とを有しており、昇降部材は押圧部材を含めた自荷重で縦ガイドに沿って落下する状態に保持されているものとすることができる。   The leveling means includes a vertical guide provided at the side of the accumulation preparation position with the longitudinal direction oriented in the vertical direction, an elevating member provided vertically movable along the vertical guide, and an elevating member provided on the elevating member. And a pressing member that switches between a pressing state that protrudes toward the upper surface of the conveyed product carried into the accumulation preparation position and a retracted state that separates from the conveyed product, and the lifting member includes the pressing member It can be held in a state of falling along the longitudinal guide by its own load.

このような構成であると、搬送物に押圧負荷(搬送物の上面を下方へ押圧する力)を付与するための動力が不要となり、構成の簡潔化が図れる利点がある。
前記均し手段の押圧部材は、集積準備位置に搬入された搬送物の上方へロッドを伸縮させる流体圧シリンダのロッドにより構成されているものとするのが好適である。
前記均し手段は、集積準備位置を挟んだ両側部において互いに対向する配置で一対、設けられており、集積準備位置に搬入された集積単位で最初となる搬送物に対して片側の均し手段が択一的に押圧負荷を付与可能となっているものとすることができる。
With such a configuration, there is no need for power for applying a pressing load (force for pressing the upper surface of the conveyed product downward) to the conveyed product, and there is an advantage that the configuration can be simplified.
It is preferable that the pressing member of the leveling means is constituted by a rod of a fluid pressure cylinder that extends and contracts the rod above the conveyed product carried into the accumulation preparation position.
The leveling means is provided in a pair facing each other on both sides sandwiching the accumulation preparation position, and is provided on one side with respect to the first transported object in the accumulation unit carried into the accumulation preparation position. Alternatively, a pressing load can be applied.

このような構成であると、片側の均し手段が押圧負荷を付与しているときに、他方側の均し手段を次ぎの集積作業に向けて準備させること(所定位置へ移動させる等)が可能になるので、集積装置としての作動効率を高めることができる。
前記持ち上げ手段は、集積準備位置に搬入された搬送物の対向二辺に下から当接する一対の係合片と、これら一対の係合片を同期させて上昇させる上昇機構とを有しているものとすることができる。
With such a configuration, when the one-side leveling means applies a pressing load, the other-side leveling means is prepared for the next stacking operation (such as moving to a predetermined position). As a result, the operation efficiency of the integrated device can be increased.
The lifting means has a pair of engaging pieces that come into contact with the opposite two sides of the conveyed product carried into the accumulation preparation position from below, and a lifting mechanism that raises the pair of engaging pieces synchronously. Can be.

前記持ち上げ手段の上昇機構は、一対の係合片が当接する搬送物の対向辺部に各々平行して設けられた一対の回動軸と、これら一対の回動軸を同期回動させる回動駆動部とを有しており、一対の回動軸にはそれらの軸心まわりに放射状配置で複数の係合片が突出して設けられ、回動駆動部は各回動軸から互いに向き合って突出する係合片同士が上方移動する方向で一対の回動軸を係合片の放射状配置ピッチに合わせて間欠回動可能とされたものとすることができる。   The lifting mechanism of the lifting means includes a pair of rotation shafts provided in parallel to the opposite sides of the conveyed product with which the pair of engagement pieces abut, and a rotation for synchronously rotating the pair of rotation shafts. And a plurality of engagement pieces projecting radially around the axis of the pair of pivot shafts, and the pivot drive sections project from the respective pivot shafts facing each other. The pair of rotation shafts can be intermittently rotated according to the radial arrangement pitch of the engagement pieces in the direction in which the engagement pieces move upward.

本発明に係る集積装置では、折返し片を有することが原因で厚み方向に膨らみがあり、且つ、厚みが一定しない「のし袋」等を搬送物として、この搬送物を所定位置にて確実に積み重ねて段積み状態にし、整然と集積する作業を機械化できるものであり、これにより袋詰めなどの作業の機械化も実現することができる。   In the stacking apparatus according to the present invention, a “pouch bag” or the like having a bulge in the thickness direction due to having folded pieces and having a constant thickness is used as a transported object, and the transported object is reliably stacked at a predetermined position. The work of stacking and orderly accumulating can be mechanized, whereby mechanization of work such as bagging can be realized.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 6 show a first embodiment of an integrated device 1 according to the present invention.
In the first embodiment, as shown in FIG. 2, this accumulation is performed so that the conveyed items accumulated by the accumulation device 1 are sent out toward the outlet portion of the bag making line 2 for making the resin film packaging bags. The case where the apparatus 1 is installed and the structure of the bagging line 3 is implement | achieved by this is illustrated. That is, in this bagging line 3, immediately after a predetermined number of conveyed items are collected, this accumulated conveyed item can be sent out toward the next process while being sequentially packed into a packaging bag immediately after bag making.

また、本第1実施形態において搬送物は、図7に示した「のし袋」等の袋Wとする場合を説明する。すなわち、この搬送物は、扁平な長方形状をした本体片の表側又は裏側に、その上下両短辺部から裏側に向けて一対の折返し片が生じたものである。以下では、搬送物に符号Wを、本体片に符号bを、また折返し片に符号fを適用して説明する。
なお、製袋ライン2は、フィルムの原反を保持させる原反保持部4、巻き出したフィルムの帯幅を略半減させるように二つ折りにする折り部5、フラップ等にする部品の取り付けを行う部品取付部6、印刷部7、吊り孔等を開ける加工部8、包装袋の袋幅に合わせた切断ピッチで切り出す溶断部9などが、この順番で連設されたものである。また、袋詰めライン3は、集積装置1の出口部から製袋ライン2の出口部(溶断部9の下流位置)へ向けて搬送物Wを集積単位(例えば10枚の搬送物Wを1単位とする)ごとに搬送する移送手段10、袋詰め装置11、袋詰め完了品を搬出する搬出手段12などが、この順番で連設されたものである。
Further, a case will be described in the first embodiment where the conveyed product is a bag W such as a “paste bag” shown in FIG. That is, in this conveyed product, a pair of folded pieces are generated on the front side or the back side of the flat rectangular main body piece from the upper and lower short sides to the back side. Below, the code | symbol W is applied to a conveyed product, the code | symbol b is applied to a main-body piece, and the code | symbol f is applied to a folding piece, and is demonstrated.
In addition, the bag making line 2 includes a raw fabric holding portion 4 that holds the original fabric of the film, a folding portion 5 that is folded in half so as to substantially halve the width of the unrolled film, and a part that is used as a flap or the like. A component attaching portion 6 to be performed, a printing portion 7, a processing portion 8 for opening a hanging hole, a fusing portion 9 cut out at a cutting pitch in accordance with the bag width of the packaging bag, and the like are arranged in this order. In addition, the bagging line 3 is a unit for collecting the conveyed product W from the outlet part of the stacking device 1 toward the outlet part of the bag making line 2 (downstream position of the fusing part 9) (for example, one unit of ten transported articles W). Transfer means 10, a bagging device 11, a carry-out means 12 for carrying out a bag-packed product, and the like are connected in this order.

図3に示すように、集積装置1は、装置フレーム15内に設定した集積準備位置16へ向けて搬送物Wを搬送する搬入手段17と、集積準備位置16に搬入された搬送物Wを逐一、所定高さに上昇させながら段積み状に集積するための均し手段18及び持ち上げ手段19とを有している。
本第1実施形態において、集積準備位置16は、装置フレーム15内を貫通するように架け渡されたベルトコンベア等の中央コンベア20のうち、装置フレーム15内の略中央を通過する上部領域(搬送領域)で設定されている。この中央コンベア20は、連続的に搬送駆動されるものとしてもよいし、搬送物Wの集積単位に合わせて間欠的に搬送駆動されるものとしてもよい。中央コンベア20は、帯ベルトコンベアでも紐ベルト(断面がV形や丸形等のベルト)コンベアでもよい。或いは、中央コンベア20を用いず、搬送物Wを滑らすように支持するシュートやレール、テーブルなどの上部領域として設定することもできる。
As shown in FIG. 3, the stacking apparatus 1 sequentially carries the transported object W toward the stacking preparation position 16 set in the apparatus frame 15 and the transported object W carried into the stacking preparation position 16. And leveling means 18 and lifting means 19 for accumulating in a stacked manner while being raised to a predetermined height.
In the first embodiment, the stacking preparation position 16 is an upper region (conveyance) that passes through the substantial center in the apparatus frame 15 among the central conveyor 20 such as a belt conveyor that extends across the apparatus frame 15. Area). The central conveyor 20 may be continuously transported and may be intermittently transported and driven according to the accumulation unit of the transported object W. The central conveyor 20 may be a belt belt conveyor or a string belt (belt having a cross section of V shape or round shape). Or it can also set as upper fields, such as a chute | shoot, a rail, and a table which support so that the conveyed product W may be slid without using the center conveyor 20. FIG.

また図4に示すように、この集積準備位置16と前記した移送手段10との乗り継ぎ間には、集積準備位置16が下方で移送手段10が上方となる相当距離の高低差を生じさせてある。そのため、集積準備位置16の上部で集積された後の搬送物Wを移送手段10へ移載させるために、リフト手段21を設けてある。このリフト手段21の細部構造及びその付設構造については後述する。   Further, as shown in FIG. 4, a difference in height between the accumulation preparation position 16 and the transfer means 10 is caused by a considerable distance in which the accumulation preparation position 16 is downward and the transfer means 10 is upward. . Therefore, a lift means 21 is provided to transfer the conveyed product W after being accumulated at the upper part of the accumulation preparation position 16 to the transfer means 10. The detailed structure of the lift means 21 and its attachment structure will be described later.

まず、搬入手段17について説明する。
この搬入手段17は、搬送物Wを1枚ずつ集積準備位置16へ搬送することを繰り返すように構成されたもので、図3に示すように、本第1実施形態では搬送物Wの搬送方向に沿って、装填台23と切り出し手段24と姿勢調整手段25と送出コンベア26とが、この順番で互いに連結されたものとなっている。
First, the carrying-in means 17 will be described.
The carry-in means 17 is configured to repeat the conveyance of the conveyed product W one by one to the accumulation preparation position 16, and as shown in FIG. 3, in the first embodiment, the conveyance direction of the conveyed product W A loading table 23, a cutting-out means 24, a posture adjusting means 25, and a delivery conveyor 26 are connected to each other in this order.

装填台23は、作業者による手作業又は移載装置などにより、多数枚の搬送物Wを集積作業へ向けて装填する部分であって、駆動式又は非駆動式のベルトコンベアやシュート、テーブル等によって構成されている。この装填台23上に対し、搬送物Wは、折返し片fを互いに挟み込ませながら重ね合わせ、本体片bにおける一方の長辺部を下に向けるように起立させて載置する(図2参照)。また、折返し片fが搬送方向の下流側(集積準備位置16の方向)へ向くようにする。この装填台23には、載置された搬送物Wが上方や搬
送方向の左右側方へ位置ズレを生じさせないようにするガイド部材27,28が設けられている。
The loading table 23 is a portion for loading a large number of transported articles W toward the stacking operation by manual operation or transfer device by an operator, and is a driving or non-driving belt conveyor, chute, table, etc. It is constituted by. On the loading table 23, the conveyed product W is placed with the folded pieces f sandwiched between each other, and is placed upright with one long side of the main body piece b facing downward (see FIG. 2). . Further, the folded piece f is directed to the downstream side in the transport direction (in the direction of the accumulation preparation position 16). The loading table 23 is provided with guide members 27 and 28 that prevent the loaded transported object W from being displaced upward or left and right in the transport direction.

切り出し手段24は、装填台23上に載置された多数枚の搬送物Wから1枚ずつを確実に切り出して送り出すようにする部分であって、装填台23上の最前位置(搬送方向において最も下流側)で起立する搬送物Wに当接して、当該搬送物Wに下向きの移動力を付与する縦送り型のベルトコンベア等によって構成されている。
姿勢調整手段25は、切り出し手段24によって1枚送りされた起立姿勢の搬送物Wを水平姿勢に姿勢変換させる部分であって、凸円弧形のベルト架け部が設けられた凸側ベルトコンベア30と、この凸側ベルトコンベア30における凸円弧形のベルト架け部に重合する凹円弧形のベルト架け部が設けられた凹側ベルトコンベア31とを有している。これら両ベルトコンベア30,31は、凸円弧形のベルト架け部と凹円弧形のベルト架け部との重合部分で搬送物Wを表裏両面側から挟持して搬送できるように、同速、同方向に駆動される。
The cutting means 24 is a part that reliably cuts out one by one from a large number of transported objects W placed on the loading table 23 and sends them out at the foremost position on the loading table 23 (most in the transport direction). It is configured by a longitudinal feed belt conveyor or the like that abuts on the conveyed product W standing on the downstream side and applies a downward moving force to the conveyed product W.
The posture adjusting means 25 is a portion that changes the posture of the conveyed product W in the standing posture fed by the cutting means 24 into a horizontal posture, and is a convex belt conveyor 30 provided with a convex arcuate belt linking portion. And a concave-side belt conveyor 31 provided with a concave arc-shaped belt bridging portion that overlaps with a convex arc-shaped belt bridging portion of the convex-side belt conveyor 30. These two belt conveyors 30 and 31 have the same speed so that the conveyed product W can be nipped and conveyed from both the front and back sides at the overlapping portion of the convex arc-shaped belt hanging portion and the concave arc-shaped belt hanging portion, Driven in the same direction.

送出コンベア26は、姿勢調整手段25によって水平姿勢に姿勢変換された搬送物Wを集積準備位置16へ送り出す部分であって、搬送物Wの上面側及び下面側に同時に当接するように設けられた上下一対のベルトコンベア32,33と、下側のベルトコンベア33から搬送物Wを乗り移らせて集積準備位置16まで搬送する前記中央コンベア20とによって構成されている。下側のベルトコンベア33と中央コンベア20とは一体的に(一連に)構成させることもできる。   The delivery conveyor 26 is a part that sends the conveyed product W whose posture has been changed to a horizontal posture by the posture adjusting means 25 to the accumulation preparation position 16 and is provided so as to be in contact with the upper surface side and the lower surface side of the conveyed product W simultaneously. A pair of upper and lower belt conveyors 32 and 33 and the central conveyor 20 that transfers the conveyed product W from the lower belt conveyor 33 to the accumulation preparation position 16 are configured. The lower belt conveyor 33 and the central conveyor 20 can be configured integrally (in series).

なお、このような構成の搬入手段17において、姿勢調整手段25の両ベルトコンベア30,31による重合部分や、送出コンベア26の両ベルトコンベア32,33による重合部分では、搬送物Wをその表裏両側から挟持する構成であり、搬送物Wは本体片bと折返し片fとが重合状に当接した扁平状態を保持し、また搬送中の位置ズレが防止されるようになっている。   Note that, in the carry-in means 17 having such a configuration, in the overlapped portion by the belt conveyors 30 and 31 of the posture adjusting means 25 and the overlapped portion by the both belt conveyors 32 and 33 of the delivery conveyor 26, the conveyed product W is placed on both the front and back sides. The conveyed product W maintains a flat state in which the main body piece b and the folded piece f are in contact with each other in a superposed manner, and misalignment during conveyance is prevented.

次に、持ち上げ手段19について説明する。
図4及び図5に示すように、この持ち上げ手段19は、搬入手段17によって集積準備位置16に搬送物Wが搬入されるたびに、この集積準備位置16の搬送物Wを所定高さに上昇させる部分である。持ち上げ手段19が搬送物Wを上昇させる高さは、上昇後の搬送物Wが、次ぎに集積準備位置16に搬入される搬送物Wと接触しないようになる高さとする。すなわち、この持ち上げ手段19は、集積準備位置16を開放して空きスペースにする、言い換えれば、次の搬送物Wを受け入れるための搬入スペースS(図5(B)参照)を形成させるようにする。
Next, the lifting means 19 will be described.
As shown in FIGS. 4 and 5, the lifting means 19 raises the conveyed product W at the accumulation preparation position 16 to a predetermined height every time the conveyed product W is carried into the accumulation preparation position 16 by the carrying-in means 17. It is a part to be made. The height at which the lifting means 19 raises the conveyed product W is set to such a height that the raised conveyed product W does not come into contact with the conveyed product W that is next carried into the accumulation preparation position 16. That is, the lifting means 19 opens the accumulation preparation position 16 to make an empty space. In other words, the lifting means 19 forms a carry-in space S (see FIG. 5B) for receiving the next conveyed product W. .

この持ち上げ手段19は、集積準備位置16の両側(中央コンベア20の両脇であって中央コンベア20とは接触しない位置)に振り分けて設けられた一対の係合片37,37と、これら一対の係合片37,37を同期させて上昇させる上昇機構38とを有している。
一対の係合片37,37は、集積準備位置16に搬入された搬送物Wに対し、その対向二辺に下から当接するように設けられている。本第1実施形態において、係合片37,37は板状に形成されたものとしてあり、また、集積準備位置16に搬入されて折返し片fが上側へ向けられた搬送物Wに対し、略水平状態となって折返し片f側の辺部(短辺部)の下面に面接触するようにしてある。
The lifting means 19 includes a pair of engaging pieces 37, 37 provided on both sides of the accumulation preparation position 16 (positions on both sides of the central conveyor 20 and not in contact with the central conveyor 20). It has the raising mechanism 38 which raises the engagement pieces 37 and 37 synchronously.
The pair of engagement pieces 37 are provided so as to come into contact with the opposite two sides from below with respect to the conveyed product W carried into the accumulation preparation position 16. In the first embodiment, the engagement pieces 37, 37 are formed in a plate shape, and are substantially the same with respect to the conveyed product W that is carried into the accumulation preparation position 16 and the folded piece f is directed upward. It is in a horizontal state and is in surface contact with the lower surface of the side portion (short side portion) on the folded piece f side.

上昇機構38は、一対の係合片37,37を、搬送物Wと当接する辺部とは反対側となる辺部側でそれぞれ回動軸40,40により支持する構造にして、これら回動軸40,40を回動させることにより、係合片37,37の搬送物Wと当接する辺部(回動軸40から見た突端部)を上昇させるようになっている。すなわち、回動軸40,40は、係合片37,37が当接する搬送物Wの辺部と軸心方向を平行させて設けられており、係合片37,37は、このような回動軸40,40から径方向へ突出する状態で設けられたものと言える。   The ascending mechanism 38 has a structure in which the pair of engaging pieces 37 and 37 are supported by the rotating shafts 40 and 40 on the side opposite to the side that contacts the conveyed product W, respectively. By rotating the shafts 40, 40, the side portions (protruding end portions viewed from the rotation shaft 40) of the engagement pieces 37, 37 that come into contact with the conveyed product W are raised. That is, the rotation shafts 40 and 40 are provided in parallel with the sides of the conveyed product W with which the engagement pieces 37 and 37 abut, and the engagement pieces 37 and 37 are arranged in such a manner. It can be said that it was provided in a state of projecting from the moving shafts 40, 40 in the radial direction.

回動軸40,40は、回動駆動部41によって相対逆方向へ同期回動される。回動駆動部41において、回動軸40,40を回動させる方向は、係合片37,37が当接する(
支持する)搬送物Wを上昇させる方向であることは言うまでもない。
また、回動駆動部41による回動軸40,40の回動角度は、係合片37,37が搬送物Wを上昇させることのできる範囲内(90°未満)に制限されている。すなわち、回動軸40,40を90°以上回動させると、係合片37,37の突端部間は相互離反して搬送物Wが落下してしまうので、90°未満に制限する必要がある。
The rotation shafts 40 and 40 are synchronously rotated in a relative reverse direction by a rotation drive unit 41. In the rotation drive unit 41, the engagement pieces 37 and 37 abut in the direction in which the rotation shafts 40 and 40 are rotated (
Needless to say, this is the direction in which the conveyed product W is supported.
Further, the rotation angle of the rotation shafts 40 and 40 by the rotation drive unit 41 is limited to a range (less than 90 °) in which the engagement pieces 37 and 37 can raise the conveyed product W. That is, if the rotation shafts 40 and 40 are rotated by 90 ° or more, the transported object W falls between the projecting ends of the engagement pieces 37 and 37, so that it is necessary to limit the angle to less than 90 °. is there.

具体的には、図5(A)に示すように、一対の係合片3、37は当初、略水平状態で待機しており、集積準備位置16に搬送物Wが搬入されると回動軸40,40が25°〜45°程度回動し、係合片37,37の突端部を上方へ向けて同じ角度で周移動させるものとしてある。回動駆動部41は、回動軸40,40の回動角度を細かく設定できるようにするために、動作角度を高精度に制御可能なパルスモータやサーボモータ等を駆動源43(図4参照)として、歯付きベルト等の伝動手段44で回動軸40,40へ動力を伝える構成とするのが好適である。   Specifically, as shown in FIG. 5A, the pair of engagement pieces 3 and 37 are initially waiting in a substantially horizontal state, and are rotated when the conveyed product W is carried into the accumulation preparation position 16. The shafts 40 and 40 are rotated about 25 ° to 45 °, and the protruding end portions of the engagement pieces 37 and 37 are moved upward at the same angle. The rotation drive unit 41 uses a drive source 43 (see FIG. 4) such as a pulse motor or a servo motor that can control the operation angle with high precision so that the rotation angle of the rotation shafts 40 and 40 can be set finely. ), It is preferable to transmit power to the rotary shafts 40 and 40 by transmission means 44 such as a toothed belt.

また、本第1実施形態では、各回動軸40のまわりに均等間隔の放射状配置となるようにして複数の係合片37を設けてある。回動軸40,40間において、それらのまわりに係合片37を設ける枚数及び放射状配置ピッチは同じに揃えてあり、また、回動軸40,40から集積準備位置16へ向けて対向突出するようになる係合片37,37同士が互いに対を成すものとして、水平状態で面一になる関係を保つようにしてある。   Further, in the first embodiment, a plurality of engagement pieces 37 are provided so as to be radially arranged at equal intervals around each rotation shaft 40. Between the rotary shafts 40, 40, the number of the engagement pieces 37 provided around them and the radial arrangement pitch are the same, and project from the rotary shafts 40, 40 toward the collection preparation position 16. Assuming that the engaging pieces 37, 37 that are to be paired with each other form a pair, the relationship of being flush with each other in the horizontal state is maintained.

具体的には、係合片37の放射状配置ピッチを36°として、1本の回動軸40に合計10枚の係合片37が設けられるようにしている。従って、回動駆動部41は、各回動軸40,40を36°間隔で、相対逆方向に間欠回動させることになる。
図5(B)に示すように、集積準備位置16に搬送物Wが搬入されるたびに、回動軸40,40の間欠回動によって集積準備位置16の搬送物Wが上昇されるということが繰り返されると、集積準備位置16(水平位置)の上方36°の位置で停止する係合片37,37の突端部間では、搬送物Wが次々に下側へ補充されて(積み重ねられて)ゆき、その結果として、集積単位を形成する枚数の搬送物Wが段積み状態に集積されるようになる。なお、36°の位置で停止する係合片37,37は、回動軸40,40が間欠回動するたびに、それぞれの回動軸40,40のまわりで次々に入れ替わるものであることは言うまでもない。
Specifically, the radial arrangement pitch of the engaging pieces 37 is 36 °, and a total of ten engaging pieces 37 are provided on one rotating shaft 40. Therefore, the rotation drive unit 41 intermittently rotates the rotation shafts 40 and 40 in the opposite direction at intervals of 36 °.
As shown in FIG. 5B, every time the conveyed product W is carried into the accumulation preparation position 16, the conveyed item W at the accumulation preparation position 16 is raised by the intermittent rotation of the rotation shafts 40 and 40. Is repeated, the conveyed product W is replenished downward (stacked) one after another between the projecting ends of the engagement pieces 37, 37 that stop at a position 36 ° above the accumulation preparation position 16 (horizontal position). As a result, the number of transported articles W forming the stacking unit is stacked in a stacked state. Note that the engagement pieces 37 and 37 that stop at a position of 36 ° are sequentially switched around the respective rotation shafts 40 and 40 whenever the rotation shafts 40 and 40 are intermittently rotated. Needless to say.

次に、均し手段18について説明する。
図1及び図6に示すように、均し手段18は、集積準備位置16に搬入された集積単位で最初となる搬送物W(集積が開始される最初の搬送物W)に対してその上面を下方へ押圧することで、この搬送物Wの本体片bと折返し片fとを重合状に当接させる部分である。
Next, the leveling means 18 will be described.
As shown in FIGS. 1 and 6, the leveling means 18 has an upper surface with respect to the first transport object W (the first transport object W from which the stacking is started) in the stacking unit carried into the stacking preparation position 16. Is a portion that causes the main body piece b and the folded piece f of the conveyed product W to come into contact with each other in a superposed manner.

この均し手段18が、実際に搬送物Wに対して押圧を開始するタイミングは、特に限定されるものではない。例えば、前記持ち上げ手段19が、集積単位の最初となる搬送物Wを持ち上げるときから既に、この搬送物Wを押圧開始するものとしてもよいし、集積単位を形成させる枚数の搬送物Wについて集積が完了したときに、最も上の搬送物Wを押圧開始するものとしてもよい。勿論、集積の途中から、最も上の搬送物Wを押圧開始するものとしてもよい。但し、集積が完了したときには、必ず、最も上の搬送物W(この搬送物Wは「集積単位の最初となる搬送物W」である)を押圧した状態にする。本第1実施形態では、集積の途中から押圧開始する構造を採用した。   The timing at which the leveling means 18 actually starts pressing the conveyed product W is not particularly limited. For example, the lifting means 19 may start pressing the transported object W from the time when the transported object W that is the first of the stacking units is lifted. It is good also as what starts pressing the uppermost conveyed product W when it completes. Of course, it is also possible to start pressing the uppermost conveyed object W from the middle of accumulation. However, when the stacking is completed, the uppermost transported object W (this transported object W is “the transported object W that is the first of the stacking units”) is always pressed. In the first embodiment, a structure in which pressing is started in the middle of accumulation is employed.

いずれにしても、この均し手段18は、集積単位の最初となる搬送物Wに対して下向きに押圧負荷を付与するようになっているので、集積された全ての搬送物Wが下方への押圧負荷を受けることとなり、いずれの搬送物Wも、本体片bと折返し片fとを重合状に当接させた扁平な状態に整形されるものである。
この均し手段18は、集積準備位置16の側部で長手方向を縦方向に向けて設けられた縦ガイド47と、この縦ガイド47に沿って上下動自在に設けられた昇降部材48と、この昇降部材48に設けられた押圧部材49とを有している。
In any case, since the leveling means 18 applies a downward pressure load to the transported object W that is the first of the stacking unit, all the transported articles W that are stacked are moved downward. Each of the conveyed items W is subjected to a pressing load, and is shaped into a flat state in which the main body piece b and the folded piece f are brought into contact with each other in a superposed manner.
The leveling means 18 includes a vertical guide 47 provided on the side of the accumulation preparation position 16 with the longitudinal direction oriented in the vertical direction, and an elevating member 48 provided so as to be movable up and down along the vertical guide 47. And a pressing member 49 provided on the elevating member 48.

本第1実施形態において、縦ガイド47は複数本(図例では2本)の丸棒を平行に起立させたものとしてあり、昇降部材48は、これら複数本の丸棒が上下方向に貫通されるブ
ロック体により形成されたものとしてある。また、昇降部材48には、集積準備位置16へ搬入された搬送物Wへ向く側面にブラケット50が設けられ、このブラケット50を介して押圧部材49が設けられたものとしてある。
In the first embodiment, the vertical guide 47 is a plurality of (two in the illustrated example) round bars standing in parallel, and the elevating member 48 has the plurality of round bars vertically penetrated. It is assumed that the block body is formed. Further, the lifting member 48 is provided with a bracket 50 on a side surface facing the conveyed product W carried into the accumulation preparation position 16, and a pressing member 49 is provided via the bracket 50.

昇降部材48は、押圧部材49を含めた自荷重で縦ガイド47に沿って落下する状態に保持されている。縦ガイド47に沿った昇降部材48の上下動を摺動抵抗や振動の少ない状態に保持させるために、昇降部材48に対して軟質金属製又は樹脂製の滑りガイド部材や回動自在なガイド輪などを設けるのが好適となる。
縦ガイド47が複数本の丸棒を有していることにより、昇降部材48は水平面に沿った旋回が阻止される(回り止めされる)ようになっている。なお、縦ガイド47は角棒やH断面の条材等によって形成することもでき、縦ガイド47をこれらの断面形にする場合には、昇降部材48との係合状態で昇降部材48が水平旋回をすることがないので、1本だけで構成させることも可能である。
The elevating member 48 is held in a state of falling along the vertical guide 47 with its own load including the pressing member 49. In order to keep the vertical movement of the elevating member 48 along the vertical guide 47 in a state with little sliding resistance and vibration, a sliding guide member made of soft metal or resin or a rotatable guide wheel with respect to the elevating member 48 It is preferable to provide such as.
Since the vertical guide 47 has a plurality of round bars, the elevating member 48 is prevented from turning (stopped) along the horizontal plane. The vertical guide 47 can also be formed of a square bar, a H-section strip, or the like. When the vertical guide 47 has these cross-sectional shapes, the elevating member 48 is in a horizontal state in an engaged state with the elevating member 48. Since there is no turning, it is possible to configure with only one.

押圧部材49は、集積準備位置16に搬入された搬送物Wの上面へ向けて突出する押圧状態と、搬送物Wから離反する退避状態とに切替動作するようになったもので、具体的には、搬送物Wの上方へロッド51aを伸縮させる流体圧シリンダ51のロッド51aにより構成されている。
なお、本第1実施形態では、搬送物Wの個々の折返し片fに各別に対応させるように、搬送物Wの長辺部で、互いに所定間隔をおいて2本の押圧部材49を設けてあり(即ち、押圧部材49は一対ある)、従って各押圧部材49に対応させるように、昇降部材48や縦ガイド47も2組設けられたものとしてある。
The pressing member 49 is configured to switch between a pressing state protruding toward the upper surface of the conveyed product W carried into the accumulation preparation position 16 and a retracted state separating from the conveyed product W. Specifically, Is constituted by a rod 51a of a fluid pressure cylinder 51 that extends and contracts the rod 51a above the conveyed product W.
In the first embodiment, the two pressing members 49 are provided at predetermined intervals on the long side of the conveyed product W so as to correspond to the individual folded pieces f of the conveyed product W, respectively. Yes (that is, there is a pair of pressing members 49). Therefore, two sets of lifting members 48 and vertical guides 47 are provided so as to correspond to each pressing member 49.

ただ、このように押圧部材49を一対設けることが限定されるものではなく、搬送物Wの長辺部に相当する長さの押圧部材49を採用して両方の折返し片f,fを一度に押圧できるようにする場合には、搬送物Wの短辺部に向けて1本の押圧部材49を設けるようにしてもよく、当然に、昇降部材48や縦ガイド47も1組でよいことになる。
本第1実施形態では、均し手段18(一対の押圧部材49,49とこれらを上下動自在に保持する構造)は、集積準備位置16を挟んだ両側部において互いに対向する配置で一対、設けられたものとしている。
However, it is not limited that the pair of pressing members 49 is provided in this way, but the pressing member 49 having a length corresponding to the long side portion of the conveyed product W is employed, so that both folded pieces f and f are attached at once. In order to enable pressing, one pressing member 49 may be provided toward the short side portion of the conveyed product W, and naturally, the lifting member 48 and the vertical guide 47 may be one set. Become.
In the first embodiment, a pair of leveling means 18 (a pair of pressing members 49 and 49 and a structure for holding these members so as to be movable up and down) are provided in a pair so as to face each other on both sides of the accumulation preparation position 16. It is assumed that

これら一対の均し手段18,18は、集積準備位置16に搬入された集積単位で最初となる搬送物Wに対して、片側の均し手段18が択一的に押圧負荷を付与可能となっている。すなわち、片側の均し手段18(搬送物Wの一方の長辺部に対応する側に並んだ一対の押圧部材49,49)が搬送物Wに対して押圧負荷を付与している間に、他方側の均し手段18(搬送物Wの他方の長辺部に対応する側に並んだ一対の押圧部材49,49)は搬送物Wから離反して接触しない位置へ退避するようになっている。   The pair of leveling means 18, 18 can alternatively apply a pressing load to the first transported object W carried in the stacking preparation position 16 by the leveling means 18 on one side. ing. That is, while the one-side leveling means 18 (a pair of pressing members 49, 49 arranged on the side corresponding to one long side portion of the conveyed product W) applies a pressing load to the conveyed product W, The other-side leveling means 18 (a pair of pressing members 49, 49 arranged on the side corresponding to the other long side portion of the conveyed product W) is moved away from the conveyed product W to a position where it does not contact. Yes.

退避した均し手段18は、集積準備位置16に対応する下方の位置まで落下移動して、次ぎの集積作業に向けて準備することができる。
なお、前記したように集積準備位置16の上部で集積された後の搬送物Wは、この上方に距離をおいて設けられた移送手段10へ移載させる必要があり、このために集積準備位置16の上方にはリフト手段21が設けられている。
The retracted leveling means 18 can drop to a lower position corresponding to the accumulation preparation position 16 and prepare for the next accumulation operation.
As described above, the transported object W after being accumulated at the upper part of the accumulation preparation position 16 needs to be transferred to the transfer means 10 provided at a distance above this. A lift means 21 is provided above 16.

図1に示すように、このリフト手段21は、集積準備位置16で集積されたうち、最も下位の搬送物Wに対し、その両側下面に当接して掬い上げるように設けられた一対のリフトコンベア60,60を有している。
各リフトコンベア60は、移送手段10よりも上方となる位置(図4参照)に設けられた上側の巻掛けローラ62と、中央コンベア20の上面、即ち、集積準備位置16よりも若干高い位置(図4参照)に設けられた下側の巻掛けローラ63と、これら上下2本の巻掛けローラ62,63に架け渡されたエンドレスの伝動部材64とを有し、伝動部材64の外向き面に、掬い片65が外方突出して設けられたものとなっている。
As shown in FIG. 1, the lift means 21 is a pair of lift conveyors provided so as to abut against the lower surfaces of both sides of the lowermost transported object W accumulated at the stacking preparation position 16. 60, 60.
Each lift conveyor 60 has an upper winding roller 62 provided at a position above the transfer means 10 (see FIG. 4) and the upper surface of the central conveyor 20, that is, a position slightly higher than the stacking preparation position 16 ( 4) and an endless transmission member 64 laid between the two upper and lower winding rollers 62, 63, and the outward surface of the transmission member 64. Further, a scooping piece 65 is provided to protrude outward.

掬い片65は、下側の巻掛けローラ63のまわりで伝動部材64をUターン状に移動させたとき、持ち上げ手段19の一対の係合片37,37とは接触干渉しないが、これら係合片37,37の突端部間で搬送物Wが保持されているとき(図1(A)及び図5(B)に示した状態)には、この搬送物Wの下面と係合するように、その大きさが設定されてい
る。
The scooping piece 65 does not contact and interfere with the pair of engagement pieces 37, 37 of the lifting means 19 when the transmission member 64 is moved in a U-turn shape around the lower winding roller 63, but these engagements When the conveyed product W is held between the projecting ends of the pieces 37 and 37 (the state shown in FIGS. 1A and 5B), it is engaged with the lower surface of the conveyed product W. , Its size is set.

掬い片65は、伝動部材64の周方向で単一的に設けてもよいし、複数設けてもよい。図例では、伝動部材64の周方向に沿って互いに均等間隔をおいて3つの掬い片65を設けてある。一対のリフトコンベア60,60間において、掬い片65の設けられる数や複数設けられる場合の相互間隔は同じとされていることは言うまでもない。また、一対のリフトコンベア60,60間において、互いの掬い片65が集積準備位置16を介して面一に対向する関係を保持するものであり、且つ、互いに同期して上昇するように駆動されることも、当然である(図4中に、上側の巻掛けローラ62に連結した駆動用モータ66を示す)。   The scooping piece 65 may be provided singly in the circumferential direction of the transmission member 64, or a plurality of scooping pieces 65 may be provided. In the illustrated example, three scooping pieces 65 are provided at equal intervals along the circumferential direction of the transmission member 64. It goes without saying that between the pair of lift conveyors 60, 60, the number of scooping pieces 65 and the interval between them are the same. Further, between the pair of lift conveyors 60, 60, the scooping pieces 65 maintain the relationship of being flush with each other via the accumulation preparation position 16 and are driven to rise in synchronization with each other. Of course, the drive motor 66 connected to the upper winding roller 62 is shown in FIG.

掬い片65を複数設けておけば、先行する掬い片65によって集積後の搬送物Wを上方の移送手段10まで上昇させるのと同時に、後行する掬い片65を、次に集積される搬送物Wへ向けた待機位置へ移動させておくことが可能となり、稼働効率を高めることに繋がる利点がある。
図4に示すように、リフト手段21には、上昇させた集積後の搬送物Wを移送手段10へ乗り移らせるための押し込み手段70が設けられている。この押し込み手段70は、流体圧シリンダ71により押し板72を前進させる構造とするのが、構造簡潔となり、好適である。
If a plurality of scooping pieces 65 are provided, the transported product W after assembling is moved up to the upper transfer means 10 by the preceding scooping piece 65, and at the same time, the scooping piece 65 that follows is transported. It is possible to move to a standby position toward W, and there is an advantage that leads to an increase in operating efficiency.
As shown in FIG. 4, the lift means 21 is provided with a pushing means 70 for transferring the raised accumulated conveyed product W to the transfer means 10. It is preferable that the pushing means 70 has a structure in which the push plate 72 is advanced by the fluid pressure cylinder 71 because the structure is simple.

更に、このリフト手段21には、集積後の搬送物Wを移送手段10へ乗り移らせる高さまで上昇させるときに、集積後の搬送物Wが水平方向で位置ズレを生じることがないようにする整列枠75を設けてある(図6参照)。この整列枠75は、搬送物Wの四隅部(長辺部の両端寄り)に近接させた複数箇所(図例では4箇所としたが3箇所以下又は5箇所以上でもよい)で、長手方向を上下方向へ向けて棒材(図例ではL型アングル材)を立設させたものであって、搬送物Wが位置ズレを起こそうとすると直ちに接触する配置として、その位置ズレを防止する。   Further, the lift means 21 prevents the transported article W after stacking from being displaced in the horizontal direction when it is raised to a height at which the transported article W after stacking is transferred to the transfer means 10. An alignment frame 75 is provided (see FIG. 6). The alignment frame 75 has a plurality of locations close to the four corners (near both ends of the long side portion) of the conveyed product W (in the illustrated example, four locations are used, but three or less locations or 5 locations or more may be used). A bar material (L-shaped angle material in the example shown in the figure) is erected in the vertical direction, and the positional displacement is prevented as the arrangement where the conveyed product W comes into contact immediately when it tries to cause the positional displacement.

次に、本発明に係る集積装置1の動作状況を説明する。
図2及び図3に示すように、搬入手段17の装填台23へ多数の搬送物Wを載せると、切り出し手段24、姿勢調整手段25及び送出コンベア26を介して、搬送物Wが1枚ずつ、水平姿勢(本体片bにおける一方の長辺部が搬送方向の前方へ向けられ、この本体片bにおける両側の短辺部から上側へ折返し片f,fが向けられている姿勢)とされながら集積準備位置16へ搬送されるようになる。
Next, the operation status of the integrated device 1 according to the present invention will be described.
As shown in FIGS. 2 and 3, when a large number of articles W are placed on the loading table 23 of the loading means 17, the articles W are conveyed one by one through the cutting means 24, the posture adjusting means 25, and the delivery conveyor 26. , While being in a horizontal posture (a posture in which one long side portion of the main body piece b is directed forward in the transport direction and the folded pieces f and f are directed upward from the short side portions on both sides of the main body piece b). It is conveyed to the accumulation preparation position 16.

図5(A)及び(B)に示すように、集積準備位置16に1枚の搬送物Wが搬入されると、持ち上げ手段19が一対の係合片37,37を搬送物Wの下面に係合させ、そのまま係合片37,37を上昇させて搬送物Wを集積準備位置16の上方へ上昇させる。持ち上げ手段19は、この段階で一旦、停止(間欠停止)する。
従って、上昇後の搬送物Wは、上昇した係合片37,37の突端部によって保持され、また集積準備位置16上は開放されて、次の搬送物Wを受け入れるための搬入スペースSが形成される。
As shown in FIGS. 5A and 5B, when one transported article W is carried into the accumulation preparation position 16, the lifting means 19 places the pair of engaging pieces 37, 37 on the lower surface of the transported article W. The engagement pieces 37 and 37 are raised as they are, and the conveyed product W is raised above the accumulation preparation position 16. The lifting means 19 temporarily stops (intermittent stop) at this stage.
Accordingly, the conveyed product W after being lifted is held by the protruding end portions of the raised engagement pieces 37 and 37, and the collection preparation position 16 is opened to form a loading space S for receiving the next conveyed product W. Is done.

この状態で、搬入手段17による集積準備位置16への搬送物Wの搬入と、持ち上げ手段19による係合片37,37の上昇とが交互に繰り返される。かくして、上昇した係合片37,37の突端部間では、搬送物Wが次々に下側へ補充されて(積み重ねられて)ゆき、その結果として、集積単位を形成する枚数(例えば10枚)の搬送物Wが段積み状態に集積されるようになる。   In this state, the carrying of the conveyed product W to the accumulation preparation position 16 by the carry-in means 17 and the raising of the engagement pieces 37 and 37 by the lifting means 19 are repeated alternately. Thus, the conveyed product W is replenished (stacked) one after another between the protruding end portions of the raised engagement pieces 37, 37, and as a result, the number of sheets (for example, 10 sheets) forming an accumulation unit. The conveyed product W is accumulated in a stacked state.

搬送物Wの集積枚数は、例えば、集積準備位置16の下方に接触型又は非接触型のセンサ(図示略)を上向きに設けておき、このセンサで集積準備位置16を通過する搬送物Wを検出させて、計数することで、把握することができる。
持ち上げ手段19が搬送物Wの集積を行っている途中で、最も上の搬送物Wが所定の高さとなると、図1(A)及び図6に示すように、次に、均し手段18が一対の押圧部材49,49を集積準備位置16の上部へ進出させた状態として、この押圧部材49,49及び昇降部材48,48を下降させる。従って、最も上の搬送物Wの上面を、押圧部材49,49によって下方へ押圧することになる(この搬送物Wは集積単位で最初となる搬送物
である)。そのため、搬送物Wは折返し片fと本体片bとが重合状に当接する状態となって、折返し片fをも含めて扁平に整形されることになる。これにより搬送物Wは、厚さが一定化され、載置安定性が高まる。
For example, a contact type or non-contact type sensor (not shown) is provided upward below the accumulation preparation position 16, and the conveyance object W passing through the accumulation preparation position 16 is detected by this sensor. It is possible to grasp by detecting and counting.
If the uppermost transported object W reaches a predetermined height while the lifting means 19 is collecting the transported objects W, then the leveling means 18 is next moved as shown in FIG. 1 (A) and FIG. The pressing members 49 and 49 and the elevating members 48 and 48 are lowered while the pair of pressing members 49 and 49 are advanced to the upper part of the accumulation preparation position 16. Therefore, the upper surface of the uppermost transported object W is pressed downward by the pressing members 49, 49 (this transported object W is the first transported object in the stacking unit). Therefore, the conveyed product W will be in the state which the folding piece f and the main-body piece b contact | abutted in superposition | polymerization, and will be shape | molded flat also including the folding piece f. Thereby, the thickness of the conveyed product W is made constant, and the mounting stability is increased.

なお、押圧部材49が最も上の搬送物Wの上面を押圧した後、持ち上げ手段19が更に搬送物Wを上昇させるようになったとしても、均し手段18は上昇する搬送物Wと一緒に上昇するようになり、機械的に何ら問題はない。
むしろ、集積中又は集積完了後の全ての搬送物Wに対し、この均し手段18による下方への押圧負荷が常に付与された状態となるので、いずれの搬送物Wも、本体片bと折返し片fとを重合状に当接させた扁平な状態に整形され、また位置ズレを起こし難い状態を保持されるという利点がある。
Even if the lifting means 19 further raises the conveyed product W after the pressing member 49 presses the upper surface of the uppermost conveyed product W, the leveling means 18 is still with the ascending conveyed product W. There is no problem mechanically.
Rather, since the downward pressing load by the leveling means 18 is always applied to all the transported articles W during or after the stacking, any transported object W is folded back with the main body piece b. There is an advantage that it is shaped into a flat state in which the piece f is brought into contact with the polymer in a superposed state, and a state in which the positional deviation is hardly caused is maintained.

図1(B)に示すように、集積単位を形成する枚数の搬送物Wの集積が終わると、リフト手段21が作動して、集積準備位置16で集積されたうち、最も下の搬送物Wを掬い上げるようにしつつ、搬送物Wを上方の移送手段10の高さまで上昇させる。その後、押し込み手段70が作動して、上昇後の搬送物Wを移送手段10へ乗り移らせる。
このようにして移送手段10に乗り移った集積後の搬送物Wは、図2に示すように、製袋ライン2によって製袋された樹脂フィルム製の包装袋へ向けて、袋詰め装置11により押し込められ、袋詰めされる。そして、この袋詰め後の袋詰め完了品が搬出手段12により、次工程へ向けて送り出される。
As shown in FIG. 1B, when the stacking of the transported objects W forming the stacking unit is finished, the lift means 21 is operated to stack the transported object W at the bottom of the stacking preparation positions 16. The conveyed product W is raised to the height of the upper transfer means 10 while scooping up. Thereafter, the push-in means 70 is actuated to transfer the lifted transported article W to the transfer means 10.
As shown in FIG. 2, the transported product W that has been transferred to the transfer means 10 in this way is pushed by the bagging device 11 toward the packaging bag made of resin film that has been made by the bag making line 2. And bagged. Then, the bag-packed product after bagging is sent out to the next process by the carry-out means 12.
