本発明は、平板状被搬送物、例えば液状洗剤或いはレトルト食品等を収容するためのパウチと称されている包装袋、を１個毎順次に搬出するための搬出装置に関する。 The present invention relates to a unloading device for sequentially unloading a flat plate-shaped object to be transported, for example, a packaging bag called a pouch for accommodating liquid detergent or retort food.

パウチと称されている包装袋の如き平板状被搬送物を１個毎順次に搬出するための従来の搬出装置として、下記特許文献１に開示されている形態の搬出装置及び下記特許文献２に開示されている形態の搬出装置を挙げることができる。 As a conventional unloading device for sequentially unloading flat plates such as packaging bags called pouches one by one, the unloading device in the form disclosed in Patent Document 1 below and Patent Document 2 below. The disclosed form of the unloading device can be mentioned.

下記特許文献１に開示されている搬出装置は、搬送方向に例えば８乃至１０ｍｍ程度であるずれ寸法ずつずらして積層配列された多数の被搬送物を搬送する搬送コンベアと、最上位且つ搬送方向最下流に位置する１個の被搬送物を下方且つ搬送方向上流側に位置する他の被搬送物から分離する分離手段と、分離された１個の被搬送物を所要方向に移動する搬出手段とを具備する。 The unloading device disclosed in Patent Document 1 below includes a transport conveyor that transports a large number of objects to be transported stacked and arranged by shifting them by a deviation dimension of, for example, about 8 to 10 mm in the transport direction, and the highest level and the highest position in the transport direction.

上記特許文献１に開示されている形態の搬出装置には、多数の被搬送物を搬送方向にずれ寸法ずつずらしてコンベア上に手動で積層配列することが必要であり、かかる作業が相当煩雑である、ずれ寸法に比較的大きな誤差が発生すると１個ずつ分離することができず２個又はそれ以上の被搬送物を同時に搬出してしまうという事態が発生する傾向がある、コンベア上に多数の被搬送物を積層配列するためにはコンベアの搬送方向長さを相当長くすることが必要である、という問題が存在する。 In the unloading device of the form disclosed in Patent Document 1, it is necessary to manually stack and arrange a large number of objects to be transported on the conveyor by shifting them by the dimensions in the transport direction, which is considerably complicated. There is a tendency that if a relatively large error occurs in the deviation dimension, it cannot be separated one by one and two or more objects to be transported are carried out at the same time. There is a problem that it is necessary to considerably increase the length of the conveyor in the transport direction in order to stack and arrange the objects to be transported.

他方、上記特許文献２に開示されている形態の搬出装置には、支持手段上に積層される被搬送物の数を増大せしめると、被搬送物全体の重量が増大し、従って最下層の被搬送物の下面と支持手段の底壁との摩擦抵抗が増大し、これに起因して搬出開口を通して被搬送物を搬出することが困難になる或いは２個又はそれ以上の被搬送物を同時に搬出してしまう虞がある、という問題が存在する。 On the other hand, in the unloading device of the form disclosed in Patent Document 2, if the number of objects to be transported to be laminated on the support means is increased, the weight of the entire objects to be transported increases, and therefore the weight of the objects to be transported is the lowest layer. The frictional resistance between the lower surface of the surface and the bottom wall of the support means increases, which makes it difficult to carry out the transported object through the carry-out opening, or two or more transported objects are carried out at the same time. There is a problem that it may end up.

上記事実に鑑み、本発明者等は、先に、特願２０１６−２１１６５２の明細書及び図面において、従来の搬出装置に存在する上述したとおりの問題を解決する搬出装置として、支持手段上に多数の被搬送物を所定搬送経路に沿って起立並列配置し、最前端の被搬送物を順次に搬出すると共に１個又は複数個の被搬送物の搬出に応じて並列配置された多数の被搬送物を適宜に搬送方向下流側に移動することができる独特な形態の搬出装置を提案した（以下「先行搬出装置」という）。この先行搬送装置においては、起立並列配置した多数の被搬送物の下側縁（片端縁）と共に両側縁を規制して（即ち上側縁（他端縁）を除く３個の縁を規制して）搬出端に向けて搬送している。搬出端には最前端の被搬送物の片側縁部が当接される片側縁部規制手段が配設されている。更に、最前端の被搬送物を次の被搬送物から分離して搬出するための、吸引保持具を含む分離搬出手段も配設されている。最前端の被搬送物を次の被搬送物から分離して搬出する際には、吸引保持具を最前端の被搬送物の前面に当接せしめて最前端の被搬送物の前面の特定部位を吸引した状態で、吸引保持具を被搬送物の他側縁側に移動し、被搬送物の他側縁を規制する部材と吸引保持具との間で被搬送物を圧縮して被搬送物の一部を前方に湾曲突出させ、被搬送物の片側縁部を片側縁部規制手段から離脱せしめる。しかる後に、吸引保持具を被搬送粒の前面から後退する方向に移動し、最前端の被搬送物を次の被搬送物から分離して搬出する。 In view of the above facts, the present inventors have previously described, in the specification and drawings of Japanese Patent Application No. 2016-21165, a large number of unloading devices on the supporting means as a unloading device for solving the above-mentioned problems existing in the conventional unloading device. The objects to be transported are arranged upright in parallel along a predetermined transfer path, the frontmost objects to be transported are sequentially carried out, and a large number of objects to be transported are arranged in parallel according to the carry-out of one or more objects to be transported. We have proposed a unique form of unloading device that can appropriately move objects downstream in the transport direction (hereinafter referred to as "preceding unloading device"). In this preceding transfer device, both side edges are regulated together with the lower edge (one end edge) of a large number of objects to be transported standing in parallel (that is, three edges except the upper edge (the other end edge) are regulated. ) Transporting toward the carry-out end. A one-sided edge regulating means is provided at the carry-out end so that the one-sided edge of the object to be transported at the front end is in contact with the one-sided edge. Further, a separation and unloading means including a suction holder for separating and carrying out the frontmost object to be transported from the next object to be transported is also provided. When the frontmost object to be transported is separated from the next object to be transported, the suction holder is brought into contact with the front surface of the frontmost object to be transported to specify a specific part on the front surface of the frontmost object to be transported. The suction holder is moved to the other side edge side of the transported object, and the transported object is compressed between the member that regulates the other side edge of the transported object and the suction holder. A part of the object is curved and projected forward, and the one-sided edge portion of the object to be transported is separated from the one-sided edge portion regulating means. After that, the suction holder is moved in the direction of retreating from the front surface of the grain to be transported, and the frontmost object to be transported is separated from the next object to be transported and carried out.

而して、上記先行搬送装置も充分に満足し得るものではなく、次のとおりの解決すべき問題を有する。所定寸法の被搬送物を搬出していた状態から他の寸法の被搬送物を搬出する状態に変更する場合には、被搬送部材の他側縁を規制する部材の装着位置を変更するという比較的煩雑な手動操作を遂行することが必要である。かような手動操作を回避するためには、被搬送物の他側縁を規制する部材を省略することが意図されるが、かくすると最前端の被搬送物を搬出する際に、吸引保持具を被搬送物の他側縁側に移動し被搬送物の他側縁を規制する部材と吸引保持具との間で被搬送物を圧縮して被搬送物の一部を前方に湾曲突出させることが不可能になってしまう。 Therefore, the above-mentioned advance transfer device is not sufficiently satisfactory, and has the following problems to be solved. Comparison of changing the mounting position of the member that regulates the other side edge of the member to be transported when changing from the state in which the object to be transported of a predetermined size is carried out to the state in which the object to be transported of other dimensions is carried out. It is necessary to carry out complicated manual operations. In order to avoid such manual operation, it is intended to omit the member that regulates the other side edge of the object to be transported, but in this way, when the frontmost object to be transported is carried out, the suction holder To compress the transported object between the member that regulates the other side edge of the transported object and the suction holder so that a part of the transported object is curved and projected forward. Becomes impossible.

本発明は上記事実に鑑みてなされたものであり、その主たる技術的課題は、被搬送物の他側縁を規制する部材が存在するか否かに拘わらず、積層状態で搬送される被搬送物における最前端の被搬送物を搬出する際には、被搬送物を圧縮してその一部を前方に湾曲突出させて、被搬送物の片側縁部を片側縁部規制手段から変位せしめることができる、新規且つ改良された搬出装置を提供することである。 The present invention has been made in view of the above facts, and its main technical problem is that the transported object is transported in a laminated state regardless of whether or not there is a member that regulates the other side edge of the transported object. When carrying out the frontmost object to be transported, the object to be transported is compressed and a part thereof is curved and projected forward to displace one side edge of the object from the one-side edge regulating means. It is to provide a new and improved unloading device that can be used.

本発明者等は、更に鋭意検討及び実験を続け、分離搬出手段を被搬送物の片側縁に垂直で且つ被搬送物の前面に沿った方向に間隔をおいて配列された少なくとも一対の吸引保持具から構成することによって、上記主たる技術的課題を達成することができることを見出した。 The present inventors have continued diligent studies and experiments, and at least a pair of suction and holding means in which the separation and unloading means are arranged perpendicular to one side edge of the transported object and spaced apart along the front surface of the transported object. It was found that the above-mentioned main technical problems can be achieved by composing the ingredients.

即ち、本発明の第一の局面によれば、上記主たる課題を達成する搬出装置として、多数の平板状被搬送物を積層状態で且つ少なくともそれらの片側縁及び片端縁を規制して搬出端に向けて強制する搬送手段、最前端の被搬送物の前面片側縁部が当接される片側縁部規制手段、及び最前端の被搬送物を該片側縁部規制手段から離脱し且つ次の被搬送物から分離して該搬送手段から搬出する分離搬出手段を具備する搬出装置において、
該分離搬出手段は、被搬送物の片側縁に対して垂直で且つ被搬送物の前面に沿った方向に間隔をおいて配列された少なくとも一対の吸引保持具を含み、
該一対の吸引保持具の各々は最前端の被搬送物の前面に当接する前進位置と最前端の被搬送物の前面から離隔する方向に後退した後退位置との間を前進後退移動自在であり、該一対の吸引保持具の、該片側縁部規制手段により近接して位置する一方は、被搬送物の片側縁に垂直で且つ被搬送物の前面に沿った方向に横移動自在であり、
該一対の吸引保持具の各々は作動状態と非作動状態とに切り替え自在であり、
該一対の吸引保持具の各々は該後退位置から該前進位置に前進移動せしめられて最前端の被搬送物の前面に当接すると共に該作動状態に切り替えられ、次いで該一対の吸引保持具の該一方が該一対の吸引保持具の他方に向かって横移動され、しかる後に該一対の吸引保持具の各々が該後退位置に後退移動されると共に該一対の吸引保持具の該他方が該非作動状態に切り替えられ、次いで該一対の吸引保持具の該一方が該片側縁部規制手段に向かう方向に横移動される、
ことを特徴とする搬出装置が提供される。 That is, according to the first aspect of the present invention, as a unloading device that achieves the above-mentioned main problem, a large number of flat plate-shaped objects to be transported are laminated and at least one side edge and one end edge thereof are restricted to the unloading end. The transport means forcibly directed toward, the one-sided edge regulating means to which the front one-sided edge of the front-end transported object is abutted, and the front-end transported object are separated from the one-sided edge regulating means and the next cover. In a unloading device provided with a separate unloading means that separates from the transported object and unloads from the transport means.
The separate unloading means includes at least a pair of suction retainers arranged perpendicular to one side edge of the object to be transported and spaced apart along the front surface of the object to be transported.
Each of the pair of suction holders can move forward and backward between a forward position that abuts on the front surface of the frontmost object to be transported and a backward position that retracts in a direction away from the front surface of the frontmost object to be transported. One of the pair of suction holders, which is located closer to the one-sided edge regulating means, is vertically movable to one side edge of the object to be transported and laterally movable in a direction along the front surface of the object to be transported.
Each of the pair of suction holders can be switched between an activated state and a non-operated state.
Each of the pair of suction holders is moved forward from the retracted position to the forward position, abuts on the front surface of the object to be transported at the foremost end, and is switched to the operating state, and then the pair of suction holders. One is laterally moved towards the other of the pair of suction holders, after which each of the pair of suction holders is retracted to the retracted position and the other of the pair of suction holders is inactive. And then one of the pair of suction holders is laterally moved in the direction towards the one-sided edge regulating means.
A unloading device characterized by this is provided .

被搬送物は起立並列配置されて積層されて水平方向に該搬出端に向けて搬送され、該片側縁は該片端縁よりも短いのが好都合である。該搬送手段は被搬送物を前方に局部的に押圧する押圧片を備え、該押圧片は、被搬送物の片側縁に垂直で且つ被搬送物の前面に沿った方向において、該一対の吸引保持具の各々が被搬送物の前面に当接される部位の間に位置するのが好ましい。 It is convenient that the objects to be transported are arranged in parallel in an upright position, stacked and horizontally transported toward the carry-out end, and the one-sided edge is shorter than the one-end edge. The transport means comprises a pressing piece that locally presses the object to be transported forward, the pressing piece being the pair of suction pieces perpendicular to one side edge of the object to be transported and in a direction along the front surface of the object to be transported. It is preferable that each of the holders is located between the parts that are in contact with the front surface of the object to be transported.

本発明の搬出装置においては、被搬送物の他側縁を規制する部材が存在するか否かに拘わらず、被搬送物の片側縁に対して垂直で且つ被搬送物の前面に沿った方向に間隔をおいて配列された一対の吸引保持具を最前端の被搬送物の前面に吸着した状態で、一対の吸引保持具の一方、即ち片側縁部規制手段により近接して位置する一方を、他方に向かって横移動することによって、被搬送物を圧縮してその一部を前方に湾曲突出させて、被搬送物の片側縁部を片側縁部規制手段から離脱せしめることができる。 In the unloading device of the present invention, regardless of whether or not there is a member that regulates the other side edge of the transported object, the direction is perpendicular to one side edge of the transported object and along the front surface of the transported object. With the pair of suction holders arranged at intervals attached to the front surface of the object to be transported at the foremost end, one of the pair of suction holders, that is, the one located closer to one side edge regulating means. By laterally moving toward the other, the transported object can be compressed and a part thereof can be curved and projected forward so that the one-sided edge portion of the transported object can be separated from the one-sided edge regulating means.

以下、添付図面を参照して、本発明に従って構成された搬出装置の好適実施形態について、更に詳述する。 Hereinafter, preferred embodiments of the unloading device configured in accordance with the present invention will be described in more detail with reference to the accompanying drawings.

図１には、本発明に従って構成された搬出装置の好適実施形態の全体が簡略に図示されている。かかる搬出装置は搬送手段２を具備している。搬送手段２は、後述するとおり、多数の平板状被搬送物を積層状態で且つ少なくともそれらの片側縁及び片端縁を規制して搬出端に向けて強制する。搬送手段２は更に、支持部材４と、バックプレート６と、搬送スタンド８と、保持部材１０とを具備している。 FIG. 1 briefly illustrates the entire preferred embodiment of the unloading device configured according to the present invention. The carrying-out device is provided with the carrying means 2. As will be described later, the transporting means 2 regulates a large number of flat plate-shaped objects to be transported in a laminated state and at least one side edge and one end edge thereof and forces them toward the carry-out end. The transporting means 2 further includes a support member 4, a back plate 6, a transport stand 8, and a holding member 10.

図１と共に図２乃至図４を参照して説明すると、支持部材４は基板１２と、この基板１２を所定高さ位置にて水平状態で支持する脚１４とを備える。基板１２は実質上水平な上面を持つ矩形形状の平板であり、基板１２の長手方向即ち図２及び図３において矢印で示す方向（これを搬送方向といい、以下では前後方向ということもある）に搬送経路Ｌが規定されている。搬送経路Ｌは後述するとおりにして平板状被搬送物が搬送される経路であり、図示の実施形態においては水平且つ直線である。図１及び図３を参照することによって明確に理解されるとおり、基板１２には、搬送方向においてその上流端部から中間位置よりも幾分下流側に延出した位置まで直線状に延びる溝１６が複数形成されている。図示の実施形態においては、溝１６は３本形成されており、夫々を番号１６ａ、ｂ、ｃで示す。溝１６の夫々は相互に平行であって、基板１２の上面から下面にかけて貫通している。図３を参照することによって明確に理解されるとおり、基板１２における、溝１６ａと溝１６ｂとの間には、円形貫通孔である小孔１８が搬送方向に沿って等間隔をおいて複数個、図示の実施形態においては６個、形成されている。夫々の小孔１８は、搬送方向に見てバックプレート６の後述する後退位置（図１乃至４に示す状態（特に図３を参照されたい））から搬送方向上流側にＸだけ移動した位置を始点として、搬送方向上流側に向かってＸの間隔をおいて順次形成されている（Ｘについては後述する）。所望ならば、小孔１８を、溝１６ａと溝１６ｂとの間に形成することに代えて、又はこれと共に、溝１６ｂと溝１６ｃとの間に形成してもよい。搬送方向に対して垂直な幅方向（以下では横方向ということもある）に見て基板１２の片端部（図４における左側端部、図３における上側端部）には、基板１２の上面から上方に垂直に起立する壁２０が設けられている。壁２０は基板１２の搬送方向においてその上流端部から溝１６の下流端を幾分超えた位置まで直線状に延びている。 Explaining with reference to FIGS. 2 to 4 together with FIG. 1, the support member 4 includes a substrate 12 and legs 14 that support the substrate 12 in a horizontal state at a predetermined height position. The substrate 12 is a rectangular flat plate having a substantially horizontal upper surface, and is the longitudinal direction of the substrate 12, that is, the direction indicated by the arrow in FIGS. 2 and 3 (this is referred to as a transport direction, and may be referred to as a front-rear direction in the following). The transport path L is defined in. The transport path L is a path through which the flat plate-shaped object to be transported is transported as described later, and is horizontal and straight in the illustrated embodiment. As is clearly understood by reference to FIGS. 1 and 3, the substrate 12 has a groove 16 extending linearly from its upstream end to a position slightly downstream from the intermediate position in the transport direction. Are formed in plurality. In the illustrated embodiment, three grooves 16 are formed, and the grooves 16 are represented by numbers 16a, b, and c, respectively. Each of the grooves 16 is parallel to each other and penetrates from the upper surface to the lower surface of the substrate 12. As is clearly understood by referring to FIG. 3, a plurality of small holes 18 which are circular through holes are formed at equal intervals along the transport direction between the grooves 16a and the grooves 16b in the substrate 12. , Six are formed in the illustrated embodiment. Each of the small holes 18 is a position moved by X from the retracted position (state shown in FIGS. 1 to 4 (see particularly FIG. 3)) of the back plate 6 described later in the transport direction to the upstream side in the transport direction. As a starting point, they are sequentially formed at intervals of X toward the upstream side in the transport direction (X will be described later). If desired, the small hole 18 may be formed between the groove 16a and the groove 16b instead of, or in combination with the groove 16a. One end of the substrate 12 (the left end in FIG. 4, the upper end in FIG. 3) when viewed in the width direction perpendicular to the transport direction (hereinafter, also referred to as the lateral direction) is from the upper surface of the substrate 12. A wall 20 that stands vertically upward is provided. The wall 20 extends linearly from its upstream end to a position slightly beyond the downstream end of the groove 16 in the transport direction of the substrate 12.

壁２０の搬送方向下流端には、後述する最前端の被搬送物の前面片側縁部が当接される片側縁部規制手段２２が配設されている。片側縁部規制手段２２は上下方向に延びる断面矩形の板状部材であり、壁２０に対して垂直で且つ基板１２の幅方向内側に向かって突出している。片側縁部規制手段２２の搬送方向上流側には被搬送物と当接して搬出端を規定する当接面２４が設けられており、被搬送物が搬送手段２によって当接面２４を超えて搬送方向下流側へ強制されることが規制される。当接面２４は搬送方向に見て溝１６の下流端から後述するＸ乃至それよりも僅かに大きい距離だけ下流側に位置するのが好都合である。図示の実施形態では更に、バックプレート６を設置するための後述する設置台の脚の搬送方向上流側面には、後述する最前端の被搬送物の前面が当接される前面規制手段２６が設けられている。この前面規制手段２６は、上下方向に延びる断面矩形の棒状部材であって、搬送方向上流側面が搬送方向において当接面２４と合致することで、被搬送物が当接面２４を超えて前方に移動することがより一層確実に防止される。 At the downstream end of the wall 20 in the transport direction, a one-side edge restricting means 22 to which the front one-side edge of the object to be transported at the front end, which will be described later, comes into contact with is disposed. The one-side edge regulating means 22 is a plate-shaped member having a rectangular cross section extending in the vertical direction, and is perpendicular to the wall 20 and projects inward in the width direction of the substrate 12. A contact surface 24 is provided on the upstream side of the one-side edge regulating means 22 in the transport direction to contact the object to be transported and define the carry-out end, and the object to be transported exceeds the contact surface 24 by the transport means 2. It is regulated to be forced to the downstream side in the transport direction. It is convenient that the contact surface 24 is located downstream from the downstream end of the groove 16 in the transport direction by a distance of X or slightly larger than that, which will be described later. Further, in the illustrated embodiment, the front surface regulating means 26 to which the front surface of the object to be transported at the front end, which will be described later, is abutted is provided on the upstream side surface in the transport direction of the legs of the installation table described later for installing the back plate 6. Has been done. The front surface regulating means 26 is a rod-shaped member having a rectangular cross section extending in the vertical direction, and when the upstream side surface in the transport direction matches the contact surface 24 in the transport direction, the object to be transported is forward beyond the contact surface 24. It is even more reliably prevented from moving to.

図１乃至図４を参照して説明を続けると、基板１２の上面であって且つ搬送方向に見て溝１６よりも下流側には分離搬出手段２８が配設されている。分離搬出手段２８は、後述するとおり、最前端の被搬送物を片側縁部規制手段２２から離脱し且つ次の被搬送物から分離して搬送手段２から搬出する。分離搬出手段２８は搬送方向に対して垂直な横方向（即ち被搬送物の片側縁に対して垂直で且つ被搬送物の前面に沿った方向）に間隔を置いて配列された少なくとも一対、図示の実施形態においては４対、の吸引保持具３０ａ及び３０ｂと、一対の吸引保持具３０ａ及び３０ｂの各々が装着される一対の吸引保持具装着部材３２ａ及び３２ｂとを備える。一対の吸引保持具３０ａ及び３０ｂの各々はエラストマー材の如き可撓性を有する適宜の軟質合成樹脂から形成された椀状であり、その中央頂部には吸引孔３１（図４を参照されたい）が形成されている。一対の吸引保持具装着部材３２ａ及び３２ｂは上下方向に長い略角柱部材である。一対の吸引保持具装着部材３２ａ及び３２ｂの搬送方向上流側面には図示しない接続バルブが上下方向に間隔をおいて少なくとも１個、図示の実施形態においては４個、設置されている。夫々の接続バルブは２つの口を有し、一方の口は一対の吸引保持具３０ａ及び３０ｂの吸引孔３１の夫々に接続され、他方の口は図示しないホースを介して図示しない真空ポンプに接続されている。これにより、一対の吸引保持具３０ａ及び３０ｂの夫々の内側領域（即ち、椀の内側領域）には上記真空ポンプによって負圧を発生させることが可能となる。上記真空ポンプは作動状態と非作動状態とを適宜に切り替え自在であり、真空ポンプの作動を切り替えることで一対の吸引保持具３０ａ及び３０ｂの各々を上記負圧が生じる作動状態と生じない非作動状態とに切り替え自在である。一対の吸引保持具装着部材３２ａ及び３２ｂの各々の搬送方向下流側面にはアクチュエータ３４が各々接続されている。このアクチュエータ３４によって、一対の吸引保持具３０ａ及び３０ｂの各々は、後述する最前端の被搬送物の前面と当接する前進位置と最前端の被搬送物の前面から離隔する方向に後退した後退位置との間で搬送方向に移動自在（即ち前進後退移動自在）であると共に、少なくとも一対の吸引保持具３０ａ及び３０ｂの、片側縁部規制手段２２により近接して位置する一方３０ａは、搬送方向に対して垂直な水平方向に移動自在（即ち横移動自在）である。アクチュエータ３４は図示しない圧縮空気制御機器の一部であり、圧縮空気を作動動力源とするものである。 Continuing the description with reference to FIGS. 1 to 4, the separation / carry-out means 28 is arranged on the upper surface of the substrate 12 and on the downstream side of the groove 16 when viewed in the transport direction. As will be described later, the separate and carried-out means 28 separates the frontmost object to be transported from the one-side edge regulating means 22 and separates it from the next object to be transported and carries it out from the transport means 2. The separated unloading means 28 is shown in at least a pair arranged at intervals in a lateral direction perpendicular to the transport direction (that is, a direction perpendicular to one side edge of the transported object and along the front surface of the transported object). In the embodiment, four pairs of suction holders 30a and 30b and a pair of suction holder mounting members 32a and 32b to which each of the pair of suction holders 30a and 30b are mounted are provided. Each of the pair of suction holders 30a and 30b is a bowl shape formed of an appropriate soft synthetic resin having flexibility such as an elastomer material, and a suction hole 31 (see FIG. 4) is formed at the central top thereof. Is formed. The pair of suction holder mounting members 32a and 32b are substantially prism members that are long in the vertical direction. At least one connection valve (not shown) is installed on the upstream side surface of the pair of suction holder mounting members 32a and 32b in the transport direction at intervals in the vertical direction, and four in the illustrated embodiment. Each connection valve has two ports, one is connected to each of the suction holes 31 of the pair of suction holders 30a and 30b, and the other is connected to a vacuum pump (not shown) via a hose (not shown). Has been done. This makes it possible for the vacuum pump to generate a negative pressure in the inner regions of the pair of suction holders 30a and 30b (that is, the inner regions of the bowl). The vacuum pump can be appropriately switched between an operating state and a non-operating state, and by switching the operation of the vacuum pump, each of the pair of suction holders 30a and 30b is in an operating state in which the negative pressure is generated and in the non-operation state in which the negative pressure is not generated. It can be switched between states. An actuator 34 is connected to each of the pair of suction holder mounting members 32a and 32b on the downstream side surface in the transport direction. By this actuator 34, each of the pair of suction holders 30a and 30b is in a forward position where it comes into contact with the front surface of the frontmost object to be transported and a retracted position where it retracts in a direction away from the front surface of the frontmost object to be transported. The suction holders 30a and 30b of at least a pair of suction holders 30a and 30b, which are movable in the transport direction (that is, move forward and backward), are located closer to each other by the one-side edge regulating means 22, while 30a is located in the transport direction. On the other hand, it is movable in the horizontal direction perpendicular to it (that is, it is movable laterally). The actuator 34 is a part of a compressed air control device (not shown), and uses compressed air as an operating power source.

図５を参照して説明すると、一対の吸引保持具３０ａ及び３０ｂの各々はアクチュエータ３４によって以下のようにして周期的に移動する。即ち、一対の吸引保持具３０ａ及び３０ｂの各々は、図５（ａ）に示す後退位置から図５（ｂ）に示す前進位置に前進し、次いで一対の吸引保持具の一方３０ａが一対の吸引保持具の他方３０ｂに向かって横移動し（図５（ｃ））、しかる後に一対の吸引保持具３０ａ及び３０ｂの各々が後退位置に後退移動し（図５（ｄ））、次いで一対の吸引保持具の一方３０ａが保持した被搬送物を放出する所定位置まで片側縁部規制手段２２に近接する方向へ横移動し（図５（ｅ）及び（ｆ）。本図中において一対の吸引保持具の他方３０ｂは実線で示される）、しかる後に一対の吸引保持具の一方３０ａが一対の吸引保持具の他方３０ｂに向かって横移動して、一対の吸引保持具３０ａ及び３０ｂの各々は再び図５（ａ）に示す状態となる。 Explaining with reference to FIG. 5, each of the pair of suction holders 30a and 30b is periodically moved by the actuator 34 as follows. That is, each of the pair of suction holders 30a and 30b advances from the retracted position shown in FIG. 5A to the forward position shown in FIG. 5B, and then one of the pair of suction holders 30a sucks a pair. Laterally move towards the other 30b of the holder (FIG. 5 (c)), after which each of the pair of suction holders 30a and 30b retracts to the retracted position (FIG. 5 (d)) and then the pair of suctions. One side 30a of the holder laterally moves to a predetermined position to release the transported object in a direction close to the one-sided edge regulating means 22 (FIGS. 5 (e) and 5 (f). A pair of suction holders in this figure. The other 30b of the tool is shown by a solid line), after which one 30a of the pair of suction holders moves laterally toward the other 30b of the pair of suction holders, and each of the pair of suction holders 30a and 30b again. The state shown in FIG. 5A is obtained.

ここで、一対の吸引保持具の一方３０ａだけでなく、一対の吸引保持具の他方３０ｂも搬送方向に垂直な水平方向に移動自在（即ち横移動自在）である場合には、一対の吸引保持具３０ａ及び３０ｂの各々は、上述した図５（ｄ）に示す状態の後に、一対の吸引保持具３０ａ及び３０ｂの各々が保持した被搬送物を放出する所定位置まで片側縁部規制手段２２に近接する方向へ横移動し（図５（ｅ）及び（ｆ）。本図中において一対の吸引保持具の他方３０ｂは点線で示される）、しかる後に一対の吸引保持具３０ａ及び３０ｂの各々が横移動して再び図５（ａ）に示す状態となるようにすることも可能である。 Here, when not only one of the pair of suction holders 30a but also the other 30b of the pair of suction holders is movable in the horizontal direction perpendicular to the transport direction (that is, laterally movable), the pair of suction holders is held. After the state shown in FIG. 5D described above, each of the tools 30a and 30b is attached to the one-sided edge regulating means 22 up to a predetermined position to release the transported object held by each of the pair of suction holders 30a and 30b. Laterally move in a close direction (FIGS. 5 (e) and 5 (f); the other 30b of the pair of suction holders is shown by a dotted line in this figure), and then each of the pair of suction holders 30a and 30b It is also possible to move laterally so that the state shown in FIG. 5A is restored.

It is fixed to the pressing piece fixing member 40 in a state of being parallel to each other in the width direction. At this time, in the width direction (that is, the direction perpendicular to one side edge of the transported object and along the front surface of the transported object), each of the pair of suction holders 30a and 30b of the pressing piece 36a is the front surface of the transported object. It is preferably positioned between the parts that come into contact with the (see FIG. 5 (a) together with FIG. 3).

It becomes movable in the transport direction. Therefore, the back plate 6 disposed on the L-shaped member 42 via the pressing piece fixing member 40 also becomes movable in the transport direction. Furthermore, since the upper surface of the upstream flat plate 40a to which the back plate 6 is fixed and the downstream flat plate 40b to which the L-shaped member 42 is connected is connected by the hinge portion 40c, the back plate 6 has the hinge portion 40c.

It is movable between the retracted position and the forward position that has advanced (that is, moved in the downstream direction in the transport direction) a second predetermined distance D2 shorter than the first predetermined distance D1 from this retracted position, and is also transported as described later. It is movable between the action position that enters between two adjacent objects to be transported and the non-action position that is separated from the objects to be transported in the objects to be transported that are sequentially upright and arranged in parallel along the path L. In the illustrated embodiment, the back plate 6 moves downward from the non-acting position and is located at the acting position. When the back plate 6 is in the non-acting position, the lower end of the back plate 6 is located above the object to be transported supported by the support member 4, and when the back plate 6 is in the acting position, the lower end of the back plate 6 is located.

図１乃至図４を参照して説明を続けると、搬送スタンド８は、搬送方向において溝１６の内側に配置されている。搬送スタンド８は複数個の仕切片５４と、夫々の仕切片５４を支持固定する仕切片支持部材５６とを有する。仕切片５４は何れも上下方向に延びる棒状部材であり、上端部を除いて断面は略正方形である。仕切片５４の上端部は何れも、搬送方向幅が上方に向かって漸次低減せしめられている。仕切片支持部材５６は、幅方向に延びる複数（図示の実施形態においては７本）の幅方向支持部５８と、搬送方向に延びる一対の搬送方向支持部６０とを有する。夫々の幅方向支持部５８の搬送方向下流側面には、仕切片５４が３つずつ所定位置に固定される。この３つの仕切片５４は、搬送スタンド８が支持部材４に対して所要とおりに設置された際に、基板１２に形成された溝１６ａ乃至ｃと夫々整合するようにして（図３を参照されたい）、夫々の下端部が固定される。夫々の幅方向支持部５８は、相互に平行に且つ仕切片５４の搬送方向間隔がバックプレート６の後退位置と前進位置との間隔に対応した間隔（Ｘ）となるようにして、一対の搬送方向支持部６０の上面に固定される。一対の搬送方向支持部６０の各々の下面には搬送方向に延びる一対のレール６２が各々形成されており、このレール６２は図示しないアクチュエータを介して底板６４に連結されている。従って、搬送スタンド８は搬送方向に移動自在となる。更に、底板６４の下面にはこれを上下方向に移動自在な昇降用のアクチュエータ６６も設けられている。従って、搬送スタンド８は上下方向にも移動自在である。上記のアクチュエータは何れも図示しない圧縮空気制御機器の一部であり、圧縮空気を作動動力源とするものである。 Continuing the description with reference to FIGS. 1 to 4, the transport stand 8 is arranged inside the groove 16 in the transport direction. The transport stand 8 has a plurality of section sections 54 and a section support member 56 that supports and fixes each section 54. Each of the section pieces 54 is a rod-shaped member extending in the vertical direction, and has a substantially square cross section except for the upper end portion. In each of the upper end portions of the section 54, the width in the transport direction is gradually reduced upward. The section support member 56 has a plurality of widthwise support portions 58 (seven in the illustrated embodiment) extending in the width direction, and a pair of transport direction support portions 60 extending in the transport direction. Three partition sections 54 are fixed at predetermined positions on the downstream side surfaces of the respective width direction support portions 58 in the transport direction. The three sections 54 are aligned with the grooves 16a to c formed in the substrate 12 when the transport stand 8 is installed on the support member 4 as required (see FIG. 3). I want), the lower end of each is fixed. Each of the widthwise support portions 58 is parallel to each other and the transport direction spacing of the section 54 is a spacing (X) corresponding to the spacing between the retracted position and the forward position of the back plate 6. It is fixed to the upper surface of the directional support portion 60. A pair of rails 62 extending in the transport direction are formed on the lower surfaces of each of the pair of transport direction support portions 60, and the rails 62 are connected to the bottom plate 64 via an actuator (not shown). Therefore, the transport stand 8 is movable in the transport direction. Further, an actuator 66 for raising and lowering the bottom plate 64 so as to be movable in the vertical direction is also provided on the lower surface of the bottom plate 64. Therefore, the transport stand 8 is also movable in the vertical direction. All of the above actuators are part of compressed air control equipment (not shown), and use compressed air as the operating power source.

図７−１乃至図７−３を参照して説明すると、搬送スタンド８は上記アクチュエータによって、搬送方向下流端（最前端）の仕切片５４が搬送方向に見てバックプレート６の後退位置からＸ（＝Ｄ２）だけ後方に移動して位置する後退位置とこの後退位置から第二の所定距離Ｄ２だけ前進した前進位置（従って、前進位置における搬送方向下流端の仕切片５４とバックプレート６の後退位置とは搬送方向において同位置である）との間を移動自在であると共に、仕切片５４の夫々が、後述するとおり、搬送経路Ｌに沿って順次に起立並列配置された被搬送物における隣接する２個の被搬送物間に進入する作用位置と被搬送物間から離隔する非作用位置との間を移動自在である。図示の実施形態においては、搬送スタンド８は非作用位置から上方に移動して作用位置に位置する。搬送スタンド８が非作用位置にあるときには、仕切片５４の上端は基板１２に支持される被搬送物よりも下方、より詳細には、仕切片５４の上端が基板１２の溝１６の内部（即ち基板１２の上面と下面との間）に位置する。搬送スタンド８が作用位置にあるときには、仕切片５４の上端は基板１２の上面を超えて上方に位置する。然るに、搬送スタンド８は上記アクチュエータによって以下のような経路で周期的に移動する。即ち、搬送スタンド８は、後退位置であって且つ作用位置である後退作用位置（図７−１（ａ）、図７−３（ｈ）及び（ｉ））、前進位置であって且つ作用位置である前進作用位置（図７−１（ｂ）乃至図７−２（ｅ））、前進位置であって且つ非作用位置である前進非作用位置（図７−２（ｆ））、後退位置であって且つ非作用位置である後退非作用位置（図７−３（ｇ））に順次移動した後に、再度後退作用位置（図７−１（ａ）、図７−３（ｈ）及び（ｉ））へ移動する。 Explaining with reference to FIGS. 7-1 to 7-3, in the transport stand 8, the section 54 at the downstream end (frontmost end) in the transport direction is X from the retracted position of the back plate 6 when viewed in the transport direction by the actuator. A retreat position located by moving backward by (= D2) and a forward position advanced by a second predetermined distance D2 from this retreat position (hence, retreat of the partition 54 and the back plate 6 at the downstream end in the transport direction at the forward position). It is movable between the position and the position in the transport direction), and the sections 54 are adjacent to each other in the transported object which is sequentially arranged in parallel along the transport path L, as will be described later. It is movable between the action position that enters between the two objects to be transported and the non-action position that separates from the objects to be transported. In the illustrated embodiment, the transport stand 8 moves upward from the non-acting position and is located at the acting position. When the transport stand 8 is in the non-acting position, the upper end of the section 54 is below the object to be transported supported by the substrate 12, and more specifically, the upper end of the section 54 is inside the groove 16 of the substrate 12 (that is,). It is located between the upper surface and the lower surface of the substrate 12). When the transport stand 8 is in the working position, the upper end of the section 54 is located above the top surface of the substrate 12. However, the transfer stand 8 is periodically moved by the above actuator in the following path. That is, the transport stand 8 is a retracting action position (FIGS. 7-1 (a), 7-3 (h) and (i)) which is a retracting position and an acting position, and is an advancing position and an acting position. Forward action position (FIGS. 7-1 (b) to 7-2 (e)), forward non-action position which is forward position and non-action position (FIG. 7-2 (f)), backward position. In addition, after sequentially moving to the receding non-acting position (FIG. 7-3 (g)) which is the non-acting position, the retracting acting position (FIG. 7-1 (a), FIG. 7-3 (h) and ( i) Move to).

図１乃至図４を参照して説明を続けると、保持部材１０は、搬送方向において溝１６の内側に配設されている。保持部材１０は複数個の第一の保持片６８と複数個の第二の保持片７０とを含んでいる。第一の保持片６８は何れも仕切片５４と同一断面形状の棒状部材であるが、上端部ではなく下端部の搬送方向幅が下方に向かって漸次低減せしめられている。第一の保持片６８は基板１２の上方において第一の保持片支持部材７２によって支持固定されている。第一の保持片支持部材７２は、幅方向に延びる複数（図示の実施形態においては６本）の幅方向支持部７４と、搬送方向に延びる１つの搬送方向支持部７６とを有する。夫々の幅方向支持部７４の搬送方向上流側面には、第一の保持片６８が２つずつ所定位置に固定される。この２つの第一の保持片６８は、第一の保持片支持部材７２が後述する支持フレーム部材に配設された際に、基板１２に形成された溝１６ｂと溝１６ｃとの間で幅方向に等間隔になるようにして（図３を参照されたい）、夫々の上端部が固定される。夫々の幅方向支持部７４は、搬送経路Ｌに沿って距離Ｘをおいて平行に、搬送方向支持部７６に固定される。従って、第一の保持片６８の搬送方向間隔もバックプレート６の後退位置と前進位置との間隔に対応した間隔（Ｘ）と同一となる。 Continuing the description with reference to FIGS. 1 to 4, the holding member 10 is arranged inside the groove 16 in the transport direction. The holding member 10 includes a plurality of first holding pieces 68 and a plurality of second holding pieces 70. Each of the first holding pieces 68 is a rod-shaped member having the same cross-sectional shape as the section 54, but the width in the transport direction of the lower end portion rather than the upper end portion is gradually reduced downward. The first holding piece 68 is supported and fixed by the first holding piece supporting member 72 above the substrate 12. The first holding piece support member 72 has a plurality of widthwise support portions 74 (six in the illustrated embodiment) extending in the width direction, and one transport direction support portion 76 extending in the transport direction. Two first holding pieces 68 are fixed at predetermined positions on the upstream side surfaces of the respective width direction support portions 74 in the transport direction. The two first holding pieces 68 are arranged in the width direction between the grooves 16b and the grooves 16c formed in the substrate 12 when the first holding piece supporting member 72 is arranged on the support frame member described later. The upper ends of each are fixed so that they are evenly spaced (see FIG. 3). Each widthwise support portion 74 is fixed to the transport direction support portion 76 in parallel at a distance X along the transport path L. Therefore, the distance in the transport direction of the first holding piece 68 is also the same as the distance (X) corresponding to the distance between the retracted position and the forward position of the back plate 6.

複数個の第一の保持片６８を支持固定した第一の保持片支持部材７２は、基板１２の上方において支持フレーム部材７８によって上下方向に移動自在に支持される。支持フレーム部材７８は、基板１２の搬送方向上流端に隣接して配設され下方が開放されたコの字形状である上流フレーム部８０と、上流フレーム部８０の上辺の幅方向他端部（図４において右側端部）から搬送方向下流に向かって実質上水平に延びて設置台４６に接続固定される直線状の中間フレーム部８２と、中間フレーム部８２の搬送方向略中間部の上面に固定され下方が開放されたコの字形状である上側フレーム部８４とを有する。上側フレーム部８４において搬送方向に見て相互に対向する一対の辺の幅方向片側（図４において左側）面には、上下方向に直線状に延びる一対のレール８６が形成されており、第一の保持片支持部材７２が図示しないアクチュエータを介してレール８６に上下方向に移動自在に連結されている。従って、第一の保持片支持部材７２に固定された第一の保持片６８も上下方向に移動自在である。第一の保持片支持部材７２が支持フレーム部材７８に連結された状態にあっては、図３を参照することによって明確に理解されるとおり、第一の保持片６８は、搬送方向に見てバックプレート６の後退位置（図１乃至４に示す状態）から上流側にＸだけ移動した位置を始点として、上流側に向かってＸの間隔をおいて順次位置せしめられることとなる。 The first holding piece support member 72 that supports and fixes the plurality of first holding pieces 68 is movably supported in the vertical direction by the support frame member 78 above the substrate 12. The support frame member 78 has a U-shaped upstream frame portion 80 arranged adjacent to the upstream end of the substrate 12 in the transport direction and having an open lower portion, and the other end in the width direction of the upper side of the upstream frame portion 80. On the upper surface of the linear intermediate frame portion 82 extending substantially horizontally from the right end portion in FIG. 4 toward the downstream in the transport direction and being connected and fixed to the installation table 46, and the substantially intermediate portion in the transport direction of the intermediate frame portion 82. It has a U-shaped upper frame portion 84 that is fixed and has an open lower portion. A pair of rails 86 extending linearly in the vertical direction are formed on one side (left side in FIG. 4) in the width direction of a pair of sides facing each other in the upper frame portion 84 in the transport direction. The holding piece support member 72 is movably connected to the rail 86 in the vertical direction via an actuator (not shown). Therefore, the first holding piece 68 fixed to the first holding piece support member 72 is also movable in the vertical direction. When the first holding piece support member 72 is connected to the support frame member 78, the first holding piece 68 is viewed in the transport direction, as is clearly understood by referring to FIG. Starting from the position where the back plate 6 is moved upstream by X from the retracted position (states shown in FIGS. 1 to 4), the back plates 6 are sequentially positioned at intervals of X toward the upstream side.

第二の保持片７０は何れも上方に突出する略半球状の突部８８とこの突部８８の下面に接続されたロッド９０とから構成されている。第二の保持片７０は基板１２に形成された小孔１８に夫々収容され、図示しない連結部材及びアクチュエータにより全ての第二の保持片７０は同時に上下動自在である。上述したとおり、夫々の小孔１８は、搬送方向に見てバックプレート６の後退位置（図１乃至４に示す状態）から上流側にＸだけ移動した位置から、上流側に向かってＸの間隔をおいて順次形成されており、従って、夫々の第二の保持片７０は夫々の第一の保持片６８と搬送方向において整合している。 The second holding piece 70 is composed of a substantially hemispherical protrusion 88 projecting upward and a rod 90 connected to the lower surface of the protrusion 88. The second holding piece 70 is housed in a small hole 18 formed in the substrate 12, respectively, and all the second holding pieces 70 can be moved up and down at the same time by a connecting member and an actuator (not shown). As described above, each of the small holes 18 is spaced X from a position moved upstream by X from the retracted position of the back plate 6 (states shown in FIGS. 1 to 4) in the transport direction. Therefore, each second holding piece 70 is aligned with each first holding piece 68 in the transport direction.

図７−１乃至図７−３を参照して説明すると、保持部材１０はこれを作動させるアクチュエータによって、後述するとおり、搬送経路Ｌに沿って順次に起立並列配置された被搬送物における隣接する２個の被搬送物間に進入する作用位置（図７−２（ｅ）乃至図７−３（ｈ））と被搬送物間から離隔する非作用位置（図７−１（ａ）乃至図７−２（ｄ）、及び図７−３（ｉ））との間を移動自在である。図示の実施形態においては、第一の保持片６８は非作用位置から下方に移動して作用位置に位置し、第二の保持片７０は非作用位置から上方に移動して作用位置に位置する。第一の保持片６８が非作用位置にあるときには、第一の保持片６８の下端は基板１２に支持される被搬送物よりも上方に離隔して位置し、第一の保持片６８が作用位置にあるときには、第一の保持片６８の下端は被搬送物の上端縁（即ち他端縁）よりも下方であって基板１２の上面と対向しこれよりも僅かに上方に位置する。第二の保持片７０が非作用位置にあるときには、突部８８の上端は基板１２に支持される被搬送物よりも下方、より詳細には突部８８の上端が基板１２の小孔１８の内部（即ち上下方向に見て基板１２の上面と下面との間）に位置する。第二の保持片７０が作用位置にあるときには、突部８８の上端は上下方向に見て基板１２の上面を超えて上方に位置する。第一の保持片６８及び第二の保持片７０は適宜の制御手段により非作用位置から作用位置へ、作用位置から非作用位置へ同時に切り換わることが可能である。 Explaining with reference to FIGS. 7-1 to 7-3, the holding member 10 is adjacent to the object to be transported, which is sequentially arranged in parallel along the transport path L by an actuator for operating the holding member 10. The acting position (FIGS. 7-2 (e) to 7-3 (h)) that enters between the two objects to be transported and the non-actuating position (FIGS. 7-1 (a) to 7-3 (h)) that separates from the object to be transported. It is movable between 7-2 (d) and 7-3 (i). In the illustrated embodiment, the first holding piece 68 moves downward from the non-acting position and is located at the working position, and the second holding piece 70 moves upward from the non-acting position and is located at the working position. .. When the first holding piece 68 is in the non-acting position, the lower end of the first holding piece 68 is positioned above the object to be transported supported by the substrate 12, and the first holding piece 68 acts. When in the position, the lower end of the first holding piece 68 is below the upper end edge (that is, the other end edge) of the object to be transported, faces the upper surface of the substrate 12, and is located slightly above this. When the second holding piece 70 is in the non-acting position, the upper end of the protrusion 88 is below the object to be transported supported by the substrate 12, and more specifically, the upper end of the protrusion 88 is the small hole 18 of the substrate 12. It is located inside (that is, between the upper surface and the lower surface of the substrate 12 when viewed in the vertical direction). When the second holding piece 70 is in the working position, the upper end of the protrusion 88 is located above the upper surface of the substrate 12 when viewed in the vertical direction. The first holding piece 68 and the second holding piece 70 can be simultaneously switched from the non-action position to the action position and from the action position to the non-action position by an appropriate control means.

続いて、図５と共に図７−１乃至図７−３を参照して本発明に従って構成された搬出装置の作動について説明する。
先ず、搬出装置を作動させるのに先立って、作業者は手動で多数の被搬送物Ｃを基板１２上に搬送経路Ｌに沿って順次に起立並列した状態で配置せしめる。図７−１（ａ）に示すように、被搬送物Ｃは搬送方向に隣接する仕切片５４の間だけでなく、搬送方向下流端の仕切片５４とバックプレート６との間、及び、バックプレート６と一対の吸引保持具３０ａ及び３０ｂの各々との間にも配置する。かかる作業を行う際には、分離搬出手段２８の一対の吸引保持具３０ａ及び３０ｂの各々は非作動状態であると共に、バックプレート６は後退作用位置に、搬送スタンド８は後退作用位置に、保持部材１０（即ち、第一の保持片６８及び第二の保持片７０）は非作用位置に、夫々位置する。ここで、平板状被搬送物とは、例えば液体状洗剤或いはレトルト食品等を収容するためのパウチと称される周知の包装体であり、図６に示すとおりの所謂スタンディングパウチと称する片側縁部ＵＰ（図６における上側縁部）が他側縁部ＢＰ（図６における下側縁部）に比べて薄く、片側縁ＵＬが片端縁ＳＬ（片側縁ＵＬと他側縁ＢＬとを接続する縁であって、図６において上下方向に延びる縁）よりも短い形式のものも含む。本発明は上記スタンディングパウチを搬送するのに好適である。スタンディングパウチは、本発明の搬出装置によって搬送されている間においては片側縁部ＵＰが開放せしめられているが、本発明の搬出装置によって搬送され内容物が充填された後には片側縁部ＵＰが閉塞せしめられる。被搬送物Ｃの夫々は、片側縁ＵＬ及び片端縁ＳＬが壁２０及び基板１２の上面によって規制されると共に搬送方向において隣接する被搬送物同士が相互に面接触した状態で、実質上鉛直に起立した直立並列配置で支持される（図５（ａ）及び図７−１（ａ）を参照されたい）。 Subsequently, the operation of the unloading device configured according to the present invention will be described with reference to FIGS. 7-1 to 7-3 together with FIG.
First, prior to operating the unloading device, the operator manually arranges a large number of objects to be transported C on the substrate 12 in a state of being sequentially upright and parallel along the transport path L. As shown in FIG. 7-1 (a), the object to be transported C is not only between the section 54 adjacent to each other in the transport direction, but also between the section 54 at the downstream end in the transport direction and the back plate 6 and back. It is also placed between the plate 6 and each of the pair of suction holders 30a and 30b. When performing such work, each of the pair of suction holders 30a and 30b of the separation and carrying-out means 28 is in an inactive state, and the back plate 6 is held in the retracting action position and the transport stand 8 is held in the retracting action position. The member 10 (that is, the first holding piece 68 and the second holding piece 70) is located in the non-acting position, respectively. Here, the flat plate-shaped object to be transported is a well-known package called a pouch for accommodating, for example, a liquid detergent or retort food, and has a one-sided edge portion called a so-called standing pouch as shown in FIG. The UP (upper edge in FIG. 6) is thinner than the other side edge BP (lower edge in FIG. 6), and the one-sided edge UL is the edge connecting the one-sided edge SL (one-sided edge UL and the other side edge BL). However, it also includes a type shorter than the vertically extending edge in FIG. The present invention is suitable for transporting the standing pouch. In the standing pouch, the one-sided edge UP is opened while being conveyed by the carrying-out device of the present invention, but after being conveyed by the carrying-out device of the present invention and filled with the contents, the one-sided edge UP is opened. It is blocked. In each of the transported objects C, the one-sided edge UL and the one-end edge SL are regulated by the upper surfaces of the wall 20 and the substrate 12, and the adjacent objects to be transported are in surface contact with each other in the transport direction, and are substantially vertical. Supported in an upright parallel arrangement (see FIGS. 5 (a) and 7-1 (a)).

搬出装置の作動を開始させると、分離搬出手段２８が作動して、基板１２に支持された被搬送物Ｃの搬送を開始する。
分離搬出手段２８の作動について図５を参照して説明する。分離搬出手段２８の一対の吸引保持具３０ａ及び３０ｂはアクチュエータ３４によって以下のように作動する。即ち、最初に、一対の吸引保持具３０ａ及び３０ｂの各々は後退位置に位置する（図５（ａ））。このとき、一対の吸引保持具３０ａ及び３０ｂの各々は作動状態と非作動状態のどちらであってもよい。次いで、一対の吸引保持具３０ａ及び３０ｂの各々は前進（即ち搬送方向上流側へ移動）せしめられて最前端の被搬送物Ｃ１の前面に当接すると共に作動状態に切り替えられる（図５（ｂ））。このとき、一対の吸引保持具３０ａ及び３０ｂの各々は最前端の被搬送物Ｃ１の前面片側縁部よりも内側の表面に当接せしめられ、一対の吸引保持具３０ａ及び３０ｂの各々の椀状部位が被搬送物Ｃ１と密着して変形せしめられる。そして、一対の吸引保持具３０ａ及び３０ｂの各々は、図示しない真空ポンプによって生じた負圧により最前端の被搬送物Ｃ１を吸引してこれを保持する。次いで、一対の吸引保持具の一方３０ａが一対の吸引保持具の他方３０ｂに向かって横移動（即ち被搬送物の片側縁ＵＬに垂直で且つ被搬送物の前面に沿った方向に横移動）される（図５（ｃ））。かくすると、一対の吸引保持具３０ａ及び３０ｂの各々の間の距離が短くなる、つまり一対の吸引保持具３０ａ及び３０ｂが吸引保持する上記被搬送物Ｃ１の各部の間の距離が短くなることで、上記被搬送物Ｃ１は圧縮されてその一部が前方に湾曲突出せしめられることとなる。このとき、図示の実施形態においては、一対の吸引保持具３０ａ及び３０ｂの各々が被搬送物Ｃ１の前面に当接される部位の間において、押圧片３６ａが被搬送物Ｃを前方に局部的に押圧するため、被搬送物Ｃは予め幾分前方に凸となっている。そのため、一対の吸引保持具の一方３０ａが一対の吸引保持具の他方３０ｂに向かって横移動した際には、被搬送物Ｃ１は確実に前方に凸に湾曲突出せしめられ、最前端の被搬送物Ｃ１と、これの直後に位置（即ち前から２番目に位置）する被搬送物Ｃ２とが確実に分離せしめられる。その後に、一対の吸引保持具３０ａ及び３０ｂの各々は後退位置に後退移動されると共に一対の吸引保持具の他方３０ｂは非作動状態に切り替えられる（図５（ｄ））。この際には、図５（ｃ）に図示する状態において最前端の被搬送物Ｃ１と前から２番目に位置する被搬送物Ｃ２とが確実に分離せしめられている故に、吸引保持具３０ａ及び３０ｂは最前端の被搬送物Ｃ１のみを確実に片側縁部規制手段２２から離脱、即ち搬送手段２から搬出することができる。しかる後に、一対の吸引保持具の一方３０ａが片側縁部規制手段２２に向かう方向に横移動して所定位置に位置し、かかる所定位置にて被搬送物Ｃ１を放出する（図５（ｅ）及び（ｆ）。本図中において一対の吸引保持具の他方３０ｂは実線で示される）。被搬送物Ｃ１の放出は、一対の吸引保持具の一方３０ａが上記所定位置にて非作動状態に切り替えられると共に被搬送物Ｃ１を二点鎖線で示すニップローラーの如き適宜の送り手段９２に受け渡すことにより行われる。被搬送物Ｃ１を放出した後は、一対の吸引保持具の一方３０ａは、一対の吸引保持具の他方３０ｂに向かって横移動して、一対の吸引保持具３０ａ及び３０ｂの各々は再び図５（ａ）に示す状態となる。 When the operation of the unloading device is started, the separation unloading means 28 is activated to start the transport of the transported object C supported by the substrate 12.
The operation of the separate carrying-out means 28 will be described with reference to FIG. The pair of suction holders 30a and 30b of the separation and carrying-out means 28 are operated by the actuator 34 as follows. That is, first, each of the pair of suction holders 30a and 30b is located in the retracted position (FIG. 5A). At this time, each of the pair of suction holders 30a and 30b may be in an operating state or a non-operating state. Next, each of the pair of suction holders 30a and 30b is moved forward (that is, moved to the upstream side in the transport direction) so as to come into contact with the front surface of the object to be transported C1 at the foremost end and to be switched to the operating state (FIG. 5 (b)). ). At this time, each of the pair of suction holders 30a and 30b is brought into contact with the surface inside the front one side edge portion of the frontmost object to be transported C1, and each of the pair of suction holders 30a and 30b has a bowl shape. The portion is in close contact with the object to be transported C1 and is deformed. Then, each of the pair of suction holders 30a and 30b sucks and holds the frontmost object to be transported C1 by the negative pressure generated by the vacuum pump (not shown). Then, one 30a of the pair of suction holders laterally moves toward the other 30b of the pair of suction holders (that is, laterally moves perpendicular to one side edge UL of the transported object and along the front surface of the transported object). (Fig. 5 (c)). Thus, the distance between each of the pair of suction holders 30a and 30b is shortened, that is, the distance between each part of the object to be transported C1 sucked and held by the pair of suction holders 30a and 30b is shortened. The object to be transported C1 is compressed and a part thereof is curved and projected forward. At this time, in the illustrated embodiment, the pressing piece 36a locally moves the transported object C forward between the portions where each of the pair of suction holders 30a and 30b is in contact with the front surface of the transported object C1. The object to be transported C is preliminarily convex to the front in order to press the object C. Therefore, when one of the pair of suction holders 30a moves laterally toward the other 30b of the pair of suction holders, the object to be transported C1 is surely curved and projected forward in a convex manner, and the frontmost end to be transported is reliably transported. The object C1 and the object to be transported C2 located immediately after this (that is, the second position from the front) are surely separated. After that, each of the pair of suction holders 30a and 30b is retracted to the retracted position, and the other 30b of the pair of suction holders is switched to the inactive state (FIG. 5 (d)). At this time, in the state shown in FIG. 5 (c), the suction holder 30a and the suction holder 30a are provided because the frontmost object to be transported C1 and the object to be transported C2 located second from the front are surely separated. 30b can surely separate only the frontmost object to be transported C1 from the one-side edge regulating means 22, that is, carry it out from the transporting means 2. After that, one of the pair of suction holders 30a laterally moves in the direction toward the one-side edge regulating means 22 to be positioned at a predetermined position, and releases the transported object C1 at such a predetermined position (FIG. 5 (e)). And (f). In this figure, the other 30b of the pair of suction holders is shown by a solid line). To release the transported object C1, one of the pair of suction holders 30a is switched to the non-operating state at the predetermined position, and the transported object C1 is received by an appropriate feeding means 92 such as a nip roller indicated by a two-dot chain line. It is done by passing. After releasing the object to be transported C1, one of the pair of suction holders 30a moves laterally toward the other 30b of the pair of suction holders, and each of the pair of suction holders 30a and 30b is again shown in FIG. The state shown in (a) is obtained.

ここで、一対の吸引保持具の一方３０ａだけでなく、一対の吸引保持具の他方３０ｂも搬送方向に垂直な水平方向に移動自在（即ち横移動自在）である場合には、上述した図５（ｄ）に示す状態から、一対の吸引保持具３０ａ及び３０ｂの各々が片側縁部規制手段２２に近接する方向へ横移動して所定位置に位置し、かかる所定位置にて被搬送物Ｃ１を放出するようにしてもよい（図５（ｅ）及び（ｆ）。この場合には、被搬送物Ｃ１は一対の吸引保持具の一方３０ａだけでなく他方３０ｂによっても吸着され保持されているため、片端縁ＳＬの長さが比較的長い形式の被搬送物であっても確実に所定位置まで搬送することが可能となる。本図中において一対の吸引保持具の他方３０ｂは破線で示される）。被搬送物Ｃ１の放出は、一対の吸引保持具３０ａ及び３０ｂの各々が上記所定位置にて非作動状態に切り替えられることにより行われる。被搬送物Ｃ１を放出した後は、一対の吸引保持具３０ａ及び３０ｂの各々は横移動して再び図５（ａ）に示す状態となる。 Here, when not only one of the pair of suction holders 30a but also the other 30b of the pair of suction holders is movable in the horizontal direction perpendicular to the transport direction (that is, laterally movable), FIG. 5 described above. From the state shown in (d), each of the pair of suction holders 30a and 30b laterally moves in a direction close to the one-side edge regulating means 22 and is positioned at a predetermined position, and the transported object C1 is placed at the predetermined position. It may be discharged (FIGS. 5 (e) and 5 (f). In this case, the object to be transported C1 is attracted and held not only by one of the pair of suction holders 30a but also by the other 30b. Even if the object to be transported has a relatively long one-end edge SL, it can be reliably transported to a predetermined position. In this figure, the other 30b of the pair of suction holders is shown by a broken line. ). The release of the transported object C1 is performed by switching each of the pair of suction holders 30a and 30b to the non-operating state at the predetermined position. After releasing the transported object C1, each of the pair of suction holders 30a and 30b laterally moves to the state shown in FIG. 5A again.

従って、本発明の搬出装置においては、被搬送物Ｃの他側縁ＢＬを規制する部材が存在するか否かに拘わらず、被搬送物Ｃの片側縁ＵＬに対して垂直で且つ被搬送物の前面に沿った方向に間隔をおいて配列された一対の吸引保持具３０ａ及び３０ｂを最前端の被搬送物Ｃ１の前面に吸着した状態で、一対の吸引保持具の一方３０ａ、即ち片側縁部規制手段２２により近接して位置する一方を、他方３０ｂに向かって横移動することによって、被搬送物Ｃを圧縮してその一部を前方に湾曲突出させて、被搬送物Ｃの片側縁部を片側縁部規制手段２２から離脱せしめることができる。 Therefore, in the unloading device of the present invention, regardless of whether or not there is a member that regulates the other side edge BL of the transported object C, the transported object is perpendicular to one side edge UL of the transported object C and is transported. One of the pair of suction holders 30a, that is, one side edge, in a state where the pair of suction holders 30a and 30b arranged at intervals along the front surface of the pair of suction holders 30a and 30b are attracted to the front surface of the object to be transported C1 at the foremost end. By laterally moving one of the parts located closer to the restricting means 22 toward the other 30b, the transported object C is compressed and a part thereof is curved and projected forward, so that one side edge of the transported object C is projected. The portion can be detached from the one-sided edge regulating means 22.

分離搬出手段２８の上記作動によって被搬送物Ｃが１個乃至複数個搬出される毎に、バックプレート６及び搬送スタンド８は１個乃至複数個の被搬送物Ｃの厚さに対応した距離だけ前進する。バックプレート６及び搬送スタンド８は、バックプレート６の搬送方向下流側面に設けられた検出スイッチ３８が被搬送物Ｃに当接せしめられて（即ち検出スイッチ３８が被搬送物Ｃによって相対的に押圧されて）閉成されることで停止する。バックプレート６及び搬送スタンド８が停止した後も分離搬出手段２８の上記作動は継続して行われる。バックプレート６及び搬送スタンド８が停止した状態で分離搬出手段２８が上記作動を継続すると、分離搬出手段２８とバックプレート６との間の被搬送物Ｃの数が減少して被搬送物Ｃによる検出スイッチ３８への当接（即ち被搬送物Ｃによる検出スイッチ３８の押圧）が解除され、検出スイッチ３８は開放される。検出スイッチ３８が開放されると、バックプレート６及び搬送スタンド８は再度前進する。このようにすることで、バックプレート６による被搬送物Ｃへの過剰な押圧に起因して一対の吸引保持具３０ａ及び３０ｂの各々の被搬送物Ｃへの吸着が毀損され、分離搬出手段２８が被搬送物Ｃを適切に搬送することができなくなることが防止される。図示の実施形態においては、バックプレート６及び搬送スタンド８は共にバックプレート６に設けられた検出スイッチ３８の切り換えによってその作動が制御されていたが、所望ならば、搬送スタンド８の搬送方向下流端に位置する仕切片５４の搬送方向下流側面に第二の検出スイッチを設け、搬送スタンド８の作動が第二の検出スイッチの切り換えによってバックプレート６の作動とは独立して制御されるようにしてもよい。 Each time one or more items C to be transported are carried out by the above operation of the separation and carrying-out means 28, the back plate 6 and the transfer stand 8 are provided with a distance corresponding to the thickness of one or more items C to be transported. Advance. In the back plate 6 and the transport stand 8, the detection switch 38 provided on the downstream side surface in the transport direction of the back plate 6 is brought into contact with the transported object C (that is, the detection switch 38 is relatively pressed by the transported object C). It stops when it is closed. Even after the back plate 6 and the transport stand 8 are stopped, the above-mentioned operation of the separation / carry-out means 28 is continued. When the separation and unloading means 28 continues the above operation with the back plate 6 and the transport stand 8 stopped, the number of objects to be transported C between the separation and unloading means 28 and the back plate 6 is reduced by the objects to be transported C. The contact with the detection switch 38 (that is, the pressing of the detection switch 38 by the object to be transported C) is released, and the detection switch 38 is released. When the detection switch 38 is opened, the back plate 6 and the transfer stand 8 move forward again. By doing so, the suction of the pair of suction holders 30a and 30b to the object to be transported C is damaged due to the excessive pressing of the back plate 6 against the object to be transported C, and the separation and unloading means 28 Is prevented from being unable to properly convey the object to be conveyed. In the illustrated embodiment, the operation of both the back plate 6 and the transport stand 8 is controlled by switching the detection switch 38 provided on the back plate 6, but if desired, the downstream end of the transport stand 8 in the transport direction. A second detection switch is provided on the downstream side surface of the section 54 located in the transport direction so that the operation of the transport stand 8 is controlled independently of the operation of the back plate 6 by switching the second detection switch. May be good.

バックプレート６及び搬送スタンド８が図７−１（ａ）に示す各々の後退作用位置から図７−１（ｂ）に示す各々の前進作用位置まで前進すると、バックプレート６は前進作用位置から前進非作用位置に移動し（図７−１（ｃ））、次いで後退非作用位置に移動し（図７−２（ｄ））、しかる後に後退作用位置に移動すると共に、保持部材１０（即ち、第一の保持片６８及び第二の保持片７０）は非作用位置から作用位置に移動する（図７−２（ｅ））。保持部材１０のこの移動は、バックプレート６が前進作用位置から後退作用位置まで移動する間乃至同移動の完了後であってもよい。図７−２（ｅ）に示す状態にあっては、バックプレート６と搬送スタンド８の最前端の仕切片５４とは搬送方向において合致するが、バックプレート６を構成する押圧片３６ａ、補助押圧片３６ｂ及び３６ｃと搬送スタンド８の最前端に位置する仕切片５４とは幅方向において夫々位置が異なるため押圧片３６ａ、補助押圧片３６ｂ及び３６ｃと仕切片５４とが干渉することはない。同様に、第一の保持片６８及び第二の保持片７０と搬送スタンド８の仕切片５４とは搬送方向において合致するが、第一の保持片６８及び第二の保持片７０と搬送スタンド８の仕切片５４とは幅方向において夫々位置が異なるため第一の保持片６８及び第二の保持片７０と仕切片５４とが干渉することはない（図３を参照されたい）。バックプレート６及び保持部材１０の上記移動の間も分離搬出手段２８は基板１２に支持された被搬送物Ｃを継続して搬送し続ける。 When the back plate 6 and the transport stand 8 advance from the respective retracting action positions shown in FIG. 7-1 (a) to the respective forward acting positions shown in FIG. 7-1 (b), the back plate 6 advances from the forward acting position. It moves to the non-acting position (FIG. 7-1 (c)), then to the retracted non-acting position (FIG. 7-2 (d)), and then to the retracting acting position and the holding member 10 (ie, that is). The first holding piece 68 and the second holding piece 70) move from the non-acting position to the acting position (FIG. 7-2 (e)). This movement of the holding member 10 may be during the movement of the back plate 6 from the forward action position to the backward action position or after the movement is completed. In the state shown in FIG. 7-2 (e), the back plate 6 and the partition portion 54 at the foremost end of the transport stand 8 match in the transport direction, but the pressing piece 36a constituting the back plate 6 and the auxiliary pressing Since the pieces 36b and 36c and the section 54 located at the foremost end of the transport stand 8 are different in position in the width direction, the pressing pieces 36a, the auxiliary pressing pieces 36b and 36c and the section 54 do not interfere with each other. Similarly, the first holding piece 68 and the second holding piece 70 and the partition 54 of the transport stand 8 match in the transport direction, but the first holding piece 68 and the second holding piece 70 and the transport stand 8 are matched. Since the positions of the section 54 are different from those of the section 54 in the width direction, the first holding piece 68 and the second holding piece 70 do not interfere with the section 54 (see FIG. 3). During the above movement of the back plate 6 and the holding member 10, the separation / carrying out means 28 continuously conveys the object to be conveyed C supported by the substrate 12.

保持部材１０が非作用位置から作用位置に移動した後に、搬送スタンド８は前進作用位置から前進非作用位置に移動し（図７−２（ｆ））、次いで後退非作用位置に移動し（図７−３（ｇ））、しかる後に後退作用位置に移動する（図７−３（ｈ））。そして、搬送スタンド８が後退作用位置まで移動した後に、保持部材１０は作用位置から非作用位置に移動する（図７−３（ｉ））。搬送スタンド８及び保持部材１０の上記移動の間も分離搬出手段２８は基板１２に支持された被搬送物Ｃを連続して搬送し続ける。 After the holding member 10 moves from the non-acting position to the acting position, the transport stand 8 moves from the forward acting position to the forward non-acting position (FIG. 7-2 (f)) and then to the retracting non-acting position (FIG. 7-2 (f)). 7-3 (g)), and then move to the retracting action position (Fig. 7-3 (h)). Then, after the transport stand 8 moves to the retracting action position, the holding member 10 moves from the action position to the non-action position (FIG. 7-3 (i)). During the above movement of the transport stand 8 and the holding member 10, the separation / delivery means 28 continuously transports the object to be transported C supported by the substrate 12.

図７−３（ｉ）に示す状態と図７−１（ａ）に示す状態とは、搬送スタンド８の搬送方向最後端に位置する仕切片５４と、この仕切片５４と搬送方向において隣接する仕切片５４との間の領域における被搬送物Ｃの有無のみが相違するがそれ以外は同じ状態であり、上記作動を繰り返すことにより被搬送物Ｃを搬送し続けることができる。また、被搬送物Ｃの空いた上記領域に作業者が新たな被搬送物Ｃを補充することで被搬送物Ｃを連続して搬送し続けることが可能となる。 The state shown in FIG. 7-3 (i) and the state shown in FIG. 7-1 (a) are adjacent to the section 54 located at the end of the transport stand 8 in the transport direction and adjacent to the section 54 in the transport direction.
