Description
本発明は、コンクリートを打設する際に用いられる枠組である型枠をパネル板と枠材とに分解する型枠分解装置に関するものである。 The present invention relates to a mold disassembling apparatus for disassembling a mold, which is a frame used when placing concrete, into a panel plate and a frame material.
建築現場等においてコンクリートを打設する際に用いられる型枠は、鋼製型枠と木製型枠とに大別される。縦桟及び横桟を矩形フレーム状に組み付けた枠材に厚手のパネル板（ベニヤ板や合板からなり、コンパネとも称される）を多数の釘で固定した木製型枠は、鉄製型枠と比較して、１枚あたりの重量が軽く、コスト面でも優れている。しかしながら、木製型枠は、一度或いは複数回の使用によってパネル板が変形や破損、汚損してしまい、そのままの状態では再利用が困難であり、また、大量の木製型枠を用いることに対しては、森林資源の枯渇や破壊を招き、環境負荷が大きいという批判もある。 Formwork used when placing concrete at a construction site or the like is roughly divided into a steel formwork and a wooden formwork. A wooden formwork in which a thick panel board (made of veneer board or plywood, also called a control panel) is fixed to a frame material in which vertical and horizontal bars are assembled in a rectangular frame shape, is compared to an iron formwork. The weight per sheet is light and the cost is excellent. However, the wooden formwork is deformed, damaged, or fouled by one or more uses, and it is difficult to reuse it as it is, and the use of a large amount of wooden formwork There are also criticisms that forest resources are depleted and destroyed, and the environmental burden is large.
そこで、パネル板が変形等していない場合や、たとえ変形や損傷が生じていたとしても型枠としての使用に耐え得る程度のものである場合には、このようなパネル板をハンマやバール等を使用して手作業により枠材から取り外して再利用したり、また、使用に耐え得ない程度に変形したパネル板は枠材から取り外して廃棄する一方で枠材は再利用する等の動きが見られる。 Therefore, if the panel plate is not deformed, or if it is such that it can withstand use as a mold even if it is deformed or damaged, such a panel plate is used as a hammer, bar, etc. The panel board is removed from the frame material by hand and reused, or the panel plate deformed to the extent that it cannot be used is removed from the frame material and discarded, while the frame material is reused. It can be seen.
しかしながら、手作業によってパネル板と枠材とを分解する作業は、１枚あたりに多大な時間及び労力を費やして作業効率が悪く、しかも、ハンマやバールによって局部的な負荷を掛けた場合にパネル板や枠材が破損して分解作業前の状態よりも悪化する事態も生じ得る。 However, the work of disassembling the panel plate and the frame material by manual work is inefficient because it takes a lot of time and labor per sheet, and when a local load is applied by a hammer or bar. There may be a situation in which the plate or the frame material is broken and worse than the state before the disassembling work.
このような不具合を解消すべく、専用の装置を用いてパネル板と枠材とを分解することが試みられている。 In order to solve such problems, it has been attempted to disassemble the panel plate and the frame material using a dedicated device.
例えば、特許文献１には、切断工具を利用してパネル板のうち釘の周囲部分を刳り抜くことによって、パネル板と枠材との固定状態を解除してパネル板を枠材から取り外す態様が開示されている。
For example,
ところが、特許文献１に記載の態様は、パネル板のうち釘の周囲部分を切断工具によって刳り抜く処理が必須であるため、単一の切断工具によって釘の周囲部分を１箇所ずつ刳り抜く場合であれば、各釘の周囲部分を適切に刳り抜くことができるが、手間が掛かる。一方、複数の切断工具を所定ピッチ毎に連結して、一度の操作で複数の釘の周囲部分を刳り抜く態様であれば、釘の周囲部分を１箇所ずつ刳り抜く態様と比較して作業効率は向上すると思われるが、パネル板に対する釘の打ち込み箇所が型枠ごとに誤差がある場合には、分解作業を行う前に切断工具同士のピッチを逐一調整する必要があり、この調整が不十分な場合は、切断工具が釘に直接当たり、釘の周囲部分を適切に刳り抜くことができず、パネル板と枠材とを好適に分解することができないおそれがある。このように、特許文献１に記載の態様は、パネル板と枠材とを分解する処理の正確性（確実性）と作業効率性とを両立することが困難である。
However, the aspect described in
本発明は、このような問題に着目してなされたものであって、主たる目的は、パネル板と枠材とを的確且つ効率良く分解することが可能な型枠分解装置を提供することにある。 The present invention has been made paying attention to such problems, and a main object thereof is to provide a formwork disassembling apparatus that can disassemble a panel plate and a frame material accurately and efficiently. .
すなわち本発明の型枠分解装置は、長手方向に沿った両サイドに配される外縦桟と、前記外縦桟間に配される中間縦桟と、長手方向両端部に配される横桟とを矩形フレーム状に組み付けた枠材にパネル板を多数の釘等の固定具によって固定した型枠を、枠材とパネル板とに分解する装置であって、外縦桟を厚み方向から挟み込み得る外縦挟持機構と、中間縦桟を厚み方向から挟み込み得る中間縦桟挟持機構と、横桟を厚み方向から挟み込み得る横桟挟持機構と、隣り合う縦桟同士の間にそれぞれ配置され且つパネル板を枠材から離間する方向に押し上げる押し上げ機構とを備え、型枠を長手方向に複数の領域に分けて領域毎に枠材とパネル板とに分解するように構成し、分解する領域が横桟を含む領域である場合には、横桟挟持機構、外桟挟持機構及び中間縦桟挟持機構によって、横桟、外縦桟及び中間縦桟をそれぞれ厚み方向から挟み込んだ状態で、押し上げ機構によってパネル板を押し上げて固定具による固定状態を解除し、分解する領域が横桟を含まない領域である場合には、外桟挟持機構及び中間縦桟挟持機構によって、外縦桟及び中間縦桟を厚み方向から挟み込んだ状態で、押し上げ機構によってパネル板を押し上げて固定具による固定状態を解除することを特徴としている。 That is, the formwork disassembling apparatus according to the present invention includes an outer vertical beam arranged on both sides along the longitudinal direction, an intermediate vertical beam arranged between the outer vertical beams, and a horizontal beam arranged at both ends in the longitudinal direction. sandwiching the door formwork fixing the panel board to the frame member assembled in a rectangular frame shape by a fixture such as a large number of nails, a decomposing device to the frame member and the panel plate, the outer longitudinal bars in the thickness direction an outer vertical clamping mechanism that may look write, and an intermediate vertical桟挟lifting mechanism that can pinch an intermediate vertical bar from the thickness direction, and a lateral桟挟lifting mechanism that can pinch the rungs from a thickness direction, are arranged between the vertical桟同mechanic adjacent And a push-up mechanism that pushes the panel plate away from the frame material, and the frame is divided into a plurality of regions in the longitudinal direction, and the frame material and the panel plate are disassembled for each region. Is an area that includes a horizontal beam, The mechanism and the intermediate vertical桟挟lifting mechanism, rungs, the outer longitudinal bars and intermediate vertical bar in a state sandwiched in the thickness direction, respectively, to push up the panel plate by lifting mechanism to release the fixed state by the fixing device, degrades region If the area does not include the horizontal beam, the panel plate is pushed up by the push-up mechanism while the outer vertical beam and the intermediate vertical beam are sandwiched from the thickness direction by the outer beam holding mechanism and the intermediate vertical beam holding mechanism. It is characterized by releasing the fixed state .
ここで、桟には、長手方向に配される縦桟、及び短辺方向に配される横桟が含まれ、また、縦桟には、両サイドに配される外縦桟と外縦桟同士の間に配される中間縦桟が含まれる。 Here, the crosspiece includes a vertical crosspiece arranged in the longitudinal direction and a horizontal crosspiece arranged in the short side direction, and the vertical crosspieces include an external vertical crosspiece and an external vertical crosspiece arranged on both sides. It includes an intermediate vertical beam arranged between them.
このような型枠分解装置であれば、挟持機構で桟を挟み込むことによって枠材を当該分解装置に固定することができ、この固定した状態でパネル板を押し上げ機構によって押し上げて、このパネル板を釘等の固定具ともども枠材から分離することができる。したがって、パネル板に対する釘等の固定具の打ち込み箇所が型枠ごとに誤差があった場合であっても、パネル板を固定具と共に枠材から適切に分離することができ、パネル板のうち釘の周囲部分を刳り抜いていた態様と比較して、枠材とパネル板との分解処理を確実且つ効率良く行うことができる。枠材と、釘が刺さった状態のパネル板とに分解した後における、パネル板からの釘除去処理は別途行えばよい。 With such a mold disassembling apparatus, the frame material can be fixed to the disassembling apparatus by sandwiching the crosspiece with the clamping mechanism, and in this fixed state, the panel board is pushed up by the push-up mechanism, It can be separated from the frame material together with a fixture such as a nail. Therefore, even if the place where the fixture such as a nail is driven into the panel plate has an error for each formwork, the panel plate can be appropriately separated from the frame material together with the fixture. Compared with the embodiment in which the peripheral portion of the frame is hollowed out, the frame member and the panel plate can be reliably and efficiently decomposed. The nail removal processing from the panel plate after the frame material and the panel plate in the state where the nail is stuck may be performed separately.
特に、本発明の型枠分解装置は、各挟持機構に、各桟を厚み方向から挟み込むことが可能な一対の挟持部材を設けている。ところで、型枠における枠材は、各桟の厚み寸法や型枠の短辺方向（幅方向）に隣り合う縦桟（中間縦桟含む）同士間のピッチが規格化されているものの、型枠ごとにこれらの寸法やピッチに誤差が生じている場合がある。そして、このような各桟を、一対の挟持部材によって挟持する態様において、全ての挟持機構が、一対の挟持部材による挟持位置を常に一定の位置に再現するものであったり、挟持部材同士の最短離間距離が常に一定の寸法となるように設定したものであれば、桟の厚み寸法や縦桟同士間のピッチに誤差がある場合に、各桟を厚み方向の両側面から均等ないしほぼ均等に押圧することができず、桟における厚み方向片方側にのみ大きな負荷（押圧力）が作用して、桟が割れて破損する不具合が生じ得る。 In particular, in the formwork disassembling apparatus of the present invention, each clamping mechanism is provided with a pair of clamping members capable of clamping each crosspiece from the thickness direction. By the way, although the frame material in the formwork is standardized in the thickness dimension of each crosspiece and the pitch between vertical crosspieces (including intermediate vertical crosspieces) adjacent to each other in the short side direction (width direction) of the formwork, There may be an error in these dimensions and pitch. And in the aspect which clamps each such crosspiece with a pair of clamping members, all the clamping mechanisms always reproduce the clamping position by a pair of clamping members to a fixed position, or the shortest of the clamping members If the separation distance is always set to a constant dimension, even if there is an error in the thickness dimension of the crosspieces or the pitch between the vertical crosspieces, each crosspiece should be evenly or almost evenly spaced from both sides in the thickness direction. It cannot be pressed, and a large load (pressing force) acts only on one side in the thickness direction of the crosspiece, which may cause a problem that the crosspiece breaks and breaks.
そこで、本発明の型枠分解装置では、このような不具合の発生を防止して、パネル板と枠材との分解処理を的確且つ効率良く行えるように、各挟持機構の全てが、対をなす挟持部材のうち一方の挟持部材を他方の挟持部材に接離動作可能に構成するとともに他方の挟持部材を一方の挟持部材に接離動作可能に構成している。すなわち、挟持機構を構成する一対の挟持部材を何れも相対する挟持部材に対して接離動作可能に構成している。これにより、各挟持部材が相対する挟持部材に接近する方向、つまり桟に接近する方向への移動距離は変更自在となり、桟の厚み寸法や縦桟同士間のピッチに誤差がある場合であっても（むしろ枠材ごとにこのような誤差があるのが通常である）、各挟持部材が桟に当接して桟をその厚み方向に押圧する位置まで移動することによって、各桟を厚み方向の両側面から均等ないしほぼ均等に押圧した状態で強固に挟持することができる。このように、本発明の型枠分解装置は、各挟持機構に対する桟の相対位置や桟自体の厚み寸法に応じて、一対の挟持部材による挟持位置や、桟を挟み込んだ状態における挟持部材同士の離間寸法を変更自在に構成することにより、桟の厚み寸法や縦桟同士間のピッチに誤差がある型枠にも適切に対応でき、パネル板と枠材とを的確且つ効率良く分解することが可能である。 Therefore, in the formwork disassembling apparatus of the present invention , all of the holding mechanisms are paired so that the occurrence of such a problem can be prevented and the disassembly processing of the panel plate and the frame material can be performed accurately and efficiently. One clamping member of the clamping members is configured to be able to contact and separate from the other clamping member, and the other clamping member is configured to be able to contact and separate from one clamping member. That is, each of the pair of clamping members constituting the clamping mechanism is configured to be capable of moving toward and away from the opposing clamping members. As a result, the moving distance in the direction in which each clamping member approaches the opposing clamping member, i.e., the direction approaching the crosspiece, can be freely changed, and there is an error in the thickness dimension of the crosspiece or the pitch between the vertical crosspieces. (Rather, it is normal that there is such an error for each frame member.) By moving each clamping member to a position where it comes into contact with the beam and presses the beam in its thickness direction, each beam is moved in the thickness direction. It can be firmly held in a state where it is pressed evenly or substantially uniformly from both side surfaces. As described above, the formwork disassembling apparatus according to the present invention is configured so that the holding position by the pair of holding members or the holding members in a state where the crosspieces are sandwiched according to the relative position of the crosspieces to each holding mechanism and the thickness dimension of the crosspieces themselves. By making the separation dimension variable, it is possible to appropriately handle molds with errors in the thickness of the crosspieces and the pitch between the vertical crosspieces, and it is possible to disassemble the panel plate and the frame material accurately and efficiently. Is possible.
なお、対をなす挟持部材を何れも相対する挟持部材に対して接離動作可能にする構成は、型枠分解装置における全ての挟持機構に適用してもよく、或いは全ての挟持機構のうち選択した一つの挟持機構以外の挟持機構に適用してもよい。後者の場合、各挟持機構のうち選択した一つの挟持機構以外の挟持機構が、対をなす挟持部材のうち一方の挟持部材を他方の挟持部材に接離動作可能に構成するとともに他方の挟持部材を一方の挟持部材に接離動作可能に構成したものであり、選択した一つの挟持機構が、対をなす挟持部材のうち、何れか一方の挟持部材を、他方の移動不能な挟持部材に対して接離動作可能に構成したものである。このような構成を採用した場合、この移動不能な挟持部材に桟を当てることによって当該型枠分解装置に対する型枠の相対位置を決めし得る位置決め手段として機能させれば、別途専用の位置決め手段を設ける必要がなく、部品点数の削減に資する。 Note that the configuration in which any pair of clamping members can be moved toward and away from the opposing clamping members may be applied to all clamping mechanisms in the formwork disassembling apparatus, or selected from all clamping mechanisms. The present invention may be applied to a clamping mechanism other than the single clamping mechanism. In the latter case, a holding mechanism other than one selected holding mechanism among the holding mechanisms is configured such that one of the paired holding members can be brought into and out of contact with the other holding member, and the other holding member Is configured so as to be able to move toward and away from one of the clamping members, and one selected clamping mechanism is configured so that one of the clamping members is paired with the other non-movable clamping member. Thus, it is configured to be able to contact and separate . In the case of adopting such a configuration, if a function is provided as a positioning means that can determine the relative position of the formwork relative to the formwork disassembling apparatus by applying a crosspiece to the immovable holding member, a separate dedicated positioning means is provided. There is no need to provide it, which helps reduce the number of parts.
また、各挟持機構における挟持部材の接離動作を、例えばリンク機構等の折り畳み・伸長動作によって実現したり、或いは偏心カムの回転動作を利用して実現することも可能であるが、本発明の型枠分解装置では、各挟持機構における挟持部材を安定した直線的な接離動作とすべく、各挟持部材を接離動作させる駆動手段としてエアシリンダを用いている。これにより、各挟持部材の安定した直線的な往復動作を比較的簡素な構造によって実現することができ、メンテナンスも比較的容易に行うことができる。 Further, it is possible to realize the contact / separation operation of the clamping member in each clamping mechanism by, for example, a folding / extending operation of a link mechanism or the like, or using a rotating operation of an eccentric cam. In the mold disassembling apparatus, an air cylinder is used as a driving means for bringing the holding members into and out of contact with each other so that the holding members in the holding mechanisms are in a stable linear contact and separation operation. Thereby, the stable linear reciprocation of each clamping member can be realized with a relatively simple structure, and maintenance can also be performed relatively easily.
さらに、本発明の型枠分解装置では、各挟持機構における一対の挟持部材のうち、少なくとも一方の挟持部材に、一対の挟持部材同士間に桟を挟み込んだ状態で桟が挟持部材間から抜ける方向へ滑ることを防止する滑り止め手段を設けることができる。これにより、一対の挟持部材間に桟を挟み込んだ状態でパネル板を押し上げ機構によって上方へ押圧した際にも、桟が挟持部材間から抜け外れることを防止して良好な挟持状態を維持することができ、枠材とパネル板との分解処理を確実に行うことができる。 Furthermore, in the formwork disassembling apparatus of the present invention, in a state in which the crosspieces are pulled out from between the holding members in a state where the crosspieces are sandwiched between at least one of the pair of holding members among the pair of holding members in each holding mechanism. Non-slip means for preventing slipping can be provided. As a result, even when the panel plate is pushed upward by the push-up mechanism in a state where the crosspiece is sandwiched between the pair of holding members, the crosspiece is prevented from coming off from between the holding members, and a good holding state is maintained. And the frame member and the panel plate can be reliably decomposed.
また、本発明の型枠分解装置に適用可能な押し上げ機構としては、パネル板の下向き面に接触可能な押し上げプレートと、押し上げプレートを上下動させる上下動駆動手段とを備えたものが挙げられる。この場合、上下動駆動手段として油圧シリンダを用いれば、油圧シリンダの加圧調整により押し上げプレートの上下方向への移動速度を微調整することができ、例えば押し上げプレートがパネル板に接触して上方へ移動する範囲内における押し上げプレートの移動速度を相対的に遅く設定することにより、釘等の固定具による固定状態が解除されたパネル板が上方へ跳ね上がる不具合を回避することができ、安全性に優れたものとなる。 Further, examples of the push-up mechanism applicable to the formwork disassembling apparatus of the present invention include a push-up plate that can contact the downward surface of the panel plate, and a vertical movement drive unit that moves the push-up plate up and down. In this case, if a hydraulic cylinder is used as the vertical movement drive means, the vertical movement speed of the push-up plate can be finely adjusted by adjusting the pressure of the hydraulic cylinder. For example, the push-up plate contacts the panel plate and moves upward. By setting the moving speed of the push-up plate within the moving range to be relatively slow, it is possible to avoid the problem that the panel plate released from the fixed state by a fixing tool such as a nail jumps upward, and is excellent in safety. It will be.
本発明の型枠分解装置によれば、型枠ごとに固定具の固定箇所（釘の打ち込み箇所）や、桟の厚み寸法、或いは桟同士のピッチに誤差がある場合においても、挟持機構及び押し上げ機構によりパネル板と枠材とを的確且つ効率良く分解することが可能であり、分解作業中における枠材やパネル板の破損を防止・抑制することができ、枠材やパネル板をそれぞれ再利用可能な状態に分解することが可能になる。 According to the mold form disassembling apparatus of the present invention, even when there is an error in the fixing position of the fixing tool (the nail driving position), the thickness dimension of the crosspieces, or the pitch between the crosspieces for each formwork, It is possible to disassemble the panel plate and the frame material accurately and efficiently by the mechanism, and it is possible to prevent and suppress the breakage of the frame material and the panel plate during the disassembly work, and reuse the frame material and the panel plate respectively. It becomes possible to disassemble into possible states.

D), one clamping mechanism (second outer vertical beam clamping mechanism C in this embodiment) is configured such that one clamping member (first clamping member C1 in this embodiment) is slidable, and the other The clamping member (second clamping member C2 in the present embodiment) is configured to be non-slidable, and the clamping member (second clamping member C2) that is not slidable in this clamping mechanism (second outer vertical beam clamping mechanism C), that is, The relative position of the mold K relative to the present apparatus (former frame disassembling apparatus X) can be determined by applying one crosspiece (outer vertical crosspiece W2 in this embodiment) in the frame material W to the fixed clamping member. . That is, when a clamping mechanism (second outer vertical beam clamping mechanism C) including a clamping member (second clamping member C2) that cannot slide is set in the apparatus (former disassembly apparatus X), And when performing the disassembling work, it functions as a positioning means for determining the relative position of the mold K with respect to the present apparatus (mold disassembling apparatus X) (see FIGS. 5 and 6).
型枠Ｋのパネル板Ｐを押し上げる押し上げ機構Ｅは、図５、図６、図９及び図２２に示すように、パネル板Ｐの下向き面に接触可能な押し上げプレートＥ１と、押し上げプレートＥ１を上下動させる上下動駆動手段Ｅ２とを備えたものである。 As shown in FIGS. 5, 6, 9, and 22, the push-up mechanism E that pushes up the panel plate P of the formwork K moves the push-up plate E <b> 1 and the push-up plate E <b> 1 up and down. And a vertically moving drive means E2 to be moved.
押し上げプレートＥ１は、搬送フレームＧの長手方向（型枠Ｋの搬送方向Ｖ）に延びる平板状をなすものである。本実施形態では、押し上げプレートＥ１の長手寸法を、外縦桟挟持機構（第１外縦桟挟持機構Ｂ、第２外縦桟挟持機構Ｃ）において搬送フレームＧの長手方向（型枠Ｋの搬送方向Ｖ）に離間して設けた第１挟持部材Ｂ１同士、第１挟持部材Ｃ１同士の内法よりも大きい寸法に設定している（図２参照）。 The push-up plate E1 has a flat plate shape extending in the longitudinal direction of the transport frame G (the transport direction V of the mold frame K). In the present embodiment, the longitudinal dimension of the push-up plate E1 is determined in the longitudinal direction of the transport frame G (the transport of the formwork K) in the outer vertical rail clamping mechanism (the first outer vertical rail clamping mechanism B and the second outer vertical rail clamping mechanism C). The dimension is set to be larger than the inner dimension of the first clamping members B1 and the first clamping members C1 provided apart in the direction V) (see FIG. 2).
上下動駆動手段Ｅ２には、シリンダ本体Ｅ２１内への圧油の給排によって、先端部を押し上げプレートＥ１に連結したシリンダロッドＥ２２を高さ方向に突没動作させる油圧シリンダを適用している。また、本実施形態では、シリンダロッドＥ２２の先端部を押し上げプレートＥ１に連結した状態で押し上げプレートＥ１が水平軸Ｅ３回りに揺動（シーソー動作、首振り動作）し得るように設定している。これにより、パネル板Ｐが押し上げプレートＥ１によって押し上げられる過程で弓なりに反る方向に傾斜した場合や、パネル板Ｐの裏面（下向き面）にコンクリートが付着するなどして平らになっていない場合であっても押し上げプレートＥ１をパネル板Ｐの下向き面に当て続けることが可能になる。 A hydraulic cylinder is applied to the vertical movement drive means E2 to push and retract the cylinder rod E22 connected to the plate E1 in the height direction by supplying and discharging pressure oil into the cylinder body E21. In the present embodiment, the push-up plate E1 is set so that it can swing around the horizontal axis E3 (seesaw operation, swing-out operation) with the tip of the cylinder rod E22 connected to the push-up plate E1. As a result, when the panel plate P is tilted in the direction of bowing in the process of being pushed up by the push-up plate E1, or when the concrete is attached to the back surface (downward surface) of the panel plate P and is not flat. Even if it exists, it becomes possible to keep the push-up plate E1 in contact with the downward surface of the panel plate P.
本実施形態に係る型枠分解装置Ｘは、図５及び図６に示すように、このような押し上げ機構Ｅを、搬送フレームＧの幅方向に隣り合う縦桟（外縦桟Ｗ２、中間縦桟Ｗ３）同士の間にそれぞれ配置している。また、本実施形態では、各挟持機構と干渉しないスペース内において最大限ないしほぼ最大限の平面寸法を有する押し上げプレートＥ１を適用している。 As shown in FIGS. 5 and 6, the formwork disassembling apparatus X according to the present embodiment uses such a push-up mechanism E as a vertical beam (outer vertical beam W2, intermediate vertical beam adjacent to the conveyance frame G in the width direction). W3) are arranged between each other. Further, in the present embodiment, the push-up plate E1 having a maximum or almost maximum plane dimension in a space that does not interfere with each clamping mechanism is applied.
次に、このような型枠分解装置Ｘの使用手順及び作用について説明する。 Next, the usage procedure and operation of such a formwork disassembling apparatus X will be described.
先ず、全ての挟持機構（横桟挟持機構Ａ、第１外縦桟挟持機構Ｂ、第２外縦桟挟持機構Ｃ、中間縦桟挟持機構Ｄ）を開放状態（Ｙ）に設定しておき、また、横桟挟持機構Ａを、横桟Ｗ１を挟持不可能な高さ位置に設定しておく。そして、パネル板Ｐが枠材Ｗの上側となる表向き姿勢の型枠Ｋを搬送フレームＧ上にセットする。本実施形態では、型枠Ｋを搬送フレームＧ上にセットする前の時点で、図１２に示すように、押し上げプレートＥ１の上向き面が、横桟Ｗ１を挟持不可能な高さ位置に設定した横桟挟持機構Ａの上端（具体的には第１挟持部材Ａ１及び第２挟持部材Ａ２の上端）よりも低くなるように構成しているため、型枠Ｋを搬送フレームＧ上にセットする場合（型枠Ｋを搬送方向Ｖ下流側に搬送する場合も含む）に押し上げプレートＥ１が不意に型枠Ｋに干渉することを防止している。型枠Ｋを搬送フレームＧ上にセットする際には、型枠Ｋのうち搬送方向Ｖ下流側の横桟Ｗ１が平面視において搬送方向Ｖ下流側の横桟挟持機構Ａにおける第１挟持部材Ａ１と第２挟持部材Ａ２との間に位置付けられるようにする（図５参照）。本実施形態では、予め開放状態（Ｙ）に設定した第２外縦桟挟持機構Ｃのうち搬送方向Ｖ下流側の第２挟持部材Ｃ２に形成した切欠部Ｃｋに、枠材Ｗのうち搬送方向Ｖ下流側の横桟Ｗ１を接触させる（押し当てる）ことによって、搬送方向Ｖ下流側の横桟Ｗ１が平面視において搬送方向Ｖ下流側の横桟挟持機構Ａにおける第１挟持部材Ａ１と第２挟持部材Ａ２との間に位置付けることができるように設定している（図５参照）。 First, all the clamping mechanisms (horizontal beam clamping mechanism A, first outer vertical beam clamping mechanism B, second outer vertical beam clamping mechanism C, intermediate vertical beam clamping mechanism D) are set to the open state (Y), Further, the horizontal beam clamping mechanism A is set at a height position where the horizontal beam W1 cannot be clamped. Then, the mold frame K in the face-up posture with the panel plate P on the upper side of the frame material W is set on the transport frame G. In the present embodiment, before the mold K is set on the transport frame G, as shown in FIG. 12, the upward surface of the push-up plate E1 is set at a height position where the horizontal rail W1 cannot be clamped. When the mold K is set on the transport frame G because it is configured to be lower than the upper end of the horizontal rail clamping mechanism A (specifically, the upper ends of the first clamping member A1 and the second clamping member A2). The push-up plate E1 is prevented from inadvertently interfering with the formwork K (including the case where the formwork K is transported downstream in the transport direction V). When the mold K is set on the transport frame G, the horizontal beam W1 on the downstream side in the transport direction V of the mold K is the first clamping member A1 in the horizontal beam clamping mechanism A on the downstream side in the transport direction V in plan view. And the second clamping member A2 (see FIG. 5). In the present embodiment, in the second outer vertical beam clamping mechanism C set in the open state (Y) in advance, in the notch Ck formed in the second clamping member C2 on the downstream side in the conveyance direction V, in the conveyance direction in the frame material W. By bringing the horizontal beam W1 on the V downstream side into contact (pressing), the horizontal beam W1 on the downstream side in the transport direction V is in plan view and the second clamping member A1 and the second clamping member A1 in the horizontal beam clamping mechanism A on the downstream side in the transport direction V are seen in plan view. It is set so that it can be positioned between the holding member A2 (see FIG. 5).
また、第２挟持部材Ｃ２に形成した切欠部Ｃｋに、枠材Ｗのうち搬送方向Ｖ下流側の横桟Ｗ１を接触させる（押し当てる）とともに、第２外縦桟挟持機構Ｃにおける第２挟持部材Ｃ２のうち第１挟持部材Ｃ１に対向する面に外縦桟Ｗ２を接触させる（押し当てる）ことによって、枠材Ｗの四隅のうち一つの隅部（コーナー部）を第２外縦桟挟持機構Ｃの一部（本実施形態では第２挟持部材Ｃ２）に緊密ないしほぼ緊密にあてがうことができる。 In addition, the transverse beam W1 on the downstream side in the transport direction V of the frame material W is brought into contact with (pressed on) the notch Ck formed in the second clamping member C2, and the second clamping in the second outer vertical beam clamping mechanism C is performed. One of the four corners (corner portion) of the frame member W is clamped by bringing the outer vertical beam W2 into contact with (pressing) the surface of the member C2 facing the first clamping member C1. A part of the mechanism C (second holding member C2 in the present embodiment) can be tightly or almost tightly applied.
本実施形態に係る型枠分解装置Ｘは、共通の操作部に対して所定の操作力を付与することによって、各挟持機構（横桟挟持機構Ａ、第１外縦桟挟持機構Ｂ、第２外縦桟挟持機構Ｃ、中間縦桟挟持機構Ｄ）を、開放状態（Ｙ）と挟み込み状態（Ｚ）との間で同時ないしほぼ同時に切替可能に構成している。以下では、本実施形態の型枠分解装置Ｘの動作及び作用を明らかにするために各挟持機構（横桟挟持機構Ａ、第１外縦桟挟持機構Ｂ、第２外縦桟挟持機構Ｃ、中間縦桟挟持機構Ｄ）ごとに説明する。 The formwork disassembling apparatus X according to the present embodiment applies a predetermined operation force to a common operation unit, thereby causing each holding mechanism (the horizontal beam holding mechanism A, the first outer vertical beam holding mechanism B, the second The outer vertical beam clamping mechanism C and the intermediate vertical beam clamping mechanism D) are configured to be switchable simultaneously or substantially simultaneously between the open state (Y) and the sandwiched state (Z). Hereinafter, in order to clarify the operation and action of the formwork disassembling apparatus X of the present embodiment, each clamping mechanism (horizontal beam clamping mechanism A, first outer vertical beam clamping mechanism B, second outer vertical beam clamping mechanism C, Each intermediate vertical beam clamping mechanism D) will be described.
型枠Ｋにおける枠材Ｗの四隅のうち一つの隅部（コーナー部）を第２外縦桟挟持機構Ｃの一部（本実施形態では第２挟持部材Ｃ２）に緊密ないしほぼ緊密に接触させた状態で第２外縦桟挟持機構Ｃが開放状態（Ｙ）から挟み込み状態（Ｚ）に切り替わる動作及び作用は以下の通りである。第１挟持部材Ｃ１と第２挟持部材Ｃ２との間に外縦桟Ｗ２を位置付けた状態で、エアシリンダＣ３を引き込み駆動状態にすると、シリンダロッドＣ３２の先端部に固定した第２挟持部材Ｃ２はスライド移動不能なものであるため、シリンダロッドＣ３２の後退動作（引き込み動作）に伴って第１挟持部材Ｃ１が第２挟持部材Ｃ２に近付く方向にスライド移動する。そして、第１挟持部材Ｃ１が外縦桟Ｗ２に当接する位置までシリンダロッドＣ３２を後退させ、さらにエアシリンダＣ３を引き込み駆動状態に維持し続けると、第２外縦桟挟持機構Ｃは、一対の挟持部材（第１挟持部材Ｃ１、第２挟持部材Ｃ２）によって外縦桟Ｗ２を厚み方向から挟み込んだ挟み込み状態（Ｚ）になる（図１８参照）。また、本実施形態では、第１挟持部材Ｃ１に設けた滑り止め用鋲Ｃ５が外縦桟Ｗ２に突き刺さるため、第１挟持部材Ｃ１と第２挟持部材Ｃ２との間に一旦挟み込んだ外縦桟Ｗ２は、シリンダロッドＣ３２を引き込み駆動状態から突出駆動状態に切り替えない限り、外縦桟Ｗ２に対して外力が作用した場合であっても挟み込み状態（Ｚ）を維持することが可能である。また、ガイド軸Ｃ７に沿った第１挟持部材Ｃ１のスライド移動は、スムーズ且つ安定した動作となる。 One corner (corner portion) of the four corners of the frame material W in the mold frame K is brought into close or almost tight contact with a part of the second outer vertical beam clamping mechanism C (second clamping member C2 in this embodiment). The operation and action in which the second outer vertical beam clamping mechanism C is switched from the opened state (Y) to the sandwiched state (Z) in the state described above are as follows. When the air cylinder C3 is pulled and driven with the outer vertical rail W2 positioned between the first clamping member C1 and the second clamping member C2, the second clamping member C2 fixed to the tip of the cylinder rod C32 is Since the sliding movement is impossible, the first clamping member C1 slides in the direction approaching the second clamping member C2 as the cylinder rod C32 moves backward (retraction operation). Then, when the cylinder rod C32 is retracted to a position where the first clamping member C1 comes into contact with the outer vertical beam W2, and the air cylinder C3 is further pulled and maintained in the driving state, the second outer vertical beam clamping mechanism C is A sandwiching state (Z) is achieved in which the outer vertical rail W2 is sandwiched from the thickness direction by the sandwiching members (the first sandwiching member C1 and the second sandwiching member C2) (see FIG. 18). Further, in the present embodiment, since the anti-slip rod C5 provided on the first clamping member C1 pierces the outer vertical beam W2, the outer vertical beam once sandwiched between the first clamping member C1 and the second clamping member C2. W2 can maintain the pinching state (Z) even when an external force is applied to the outer longitudinal rail W2 unless the cylinder rod C32 is switched from the retracting driving state to the protruding driving state. Further, the sliding movement of the first clamping member C1 along the guide shaft C7 is a smooth and stable operation.
このようにして、位置決め手段として機能する第２外縦桟挟持機構Ｃによって枠材Ｗの一部（具体的には外縦枠Ｗ２）を挟持することにより、搬送フレームＧに対する型枠Ｋの相対位置を固定する。 In this way, a part of the frame material W (specifically, the outer vertical frame W2) is clamped by the second outer vertical beam clamping mechanism C functioning as positioning means, so that the mold frame K is relative to the transport frame G. Fix the position.
また、本実施形態に係る型枠分解装置Ｘは、第２外縦桟挟持機構Ｃによって外縦桟Ｗ２を挟持する前の時点で、上下動機構Ｆを駆動させて搬送方向Ｖ下流側の横桟挟持機構Ａを、横桟Ｗ１を挟持不可能な高さ位置（図１２参照）から横桟Ｗ１を挟持可能な高さ位置（図９参照）に移動させる。上下動機構Ｆを駆動させるタイミング及び操作は作業者自身の判断に基づくタイミング及び作業者自身による操作であってもよいが、本実施形態に係る型枠分解装置Ｘでは、図１７に示すように、型枠Ｋの搬送方向Ｖ下流端（型枠Ｋの先頭）を検知する位置検知手段Ｓ１を所定箇所に設け、この位置検知手段Ｓ１によって型枠Ｋの搬送方向Ｖ下流端を検知した場合に、上下動機構Ｆを作動させて搬送方向Ｖ下流側の横桟挟持機構Ａが横桟Ｗ１を挟持不可能な高さ位置から横桟Ｗ１を挟持可能な高さ位置に自動的に移動するように構成している。位置検知手段Ｓ１としては、例えば各種スイッチやセンサ等が挙げられるが、本実施形態ではリミットスイッチを用いて位置検知手段Ｓ１を構成している。本実施形態の型枠分解装置Ｘは、このような位置検知手段Ｓ１を、外縦桟挟持機構（例えば第２外縦桟挟持機構Ｃ）における搬送方向Ｖ下流側の端部に設けている。 In addition, the formwork disassembling apparatus X according to the present embodiment drives the vertical movement mechanism F at the time before the outer vertical beam W2 is clamped by the second outer vertical beam clamping mechanism C, so The beam clamping mechanism A is moved from a height position (see FIG. 12) where the horizontal beam W1 cannot be clamped to a height position (see FIG. 9) where the horizontal beam W1 can be clamped. The timing and operation for driving the vertical movement mechanism F may be a timing based on the operator's own judgment and an operation by the operator himself. However, in the formwork disassembling apparatus X according to the present embodiment, as shown in FIG. When position detection means S1 for detecting the downstream end in the conveyance direction V of the mold K (the leading edge of the mold K) is provided at a predetermined location, and the downstream end in the conveyance direction V of the mold K is detected by the position detection means S1. Then, the vertical movement mechanism F is operated so that the horizontal beam clamping mechanism A on the downstream side in the conveying direction V automatically moves from a height position where the horizontal beam W1 cannot be clamped to a height position where the horizontal beam W1 can be clamped. It is configured. Examples of the position detection unit S1 include various switches and sensors. In the present embodiment, the position detection unit S1 is configured using a limit switch. In the mold form disassembling apparatus X of the present embodiment, such position detection means S1 is provided at an end portion on the downstream side in the transport direction V in the outer vertical beam clamping mechanism (for example, the second outer vertical beam clamping mechanism C).
また、搬送方向Ｖ下流側の横桟挟持機構Ａが開放状態（Ｙ）から挟み込み状態（Ｚ）に切り替わる動作及び作用は以下の通りである。先ず、搬送方向Ｖ下流側の横桟挟持機構Ａを開放状態（Ｙ）に設定して、第１挟持部材Ａ１と第２挟持部材Ａ２との間に搬送方向Ｖ下流側の横桟Ｗ１を位置付けた状態で、エアシリンダＡ３を引き込み駆動状態にすると、シリンダロッドＡ３２の先端部に固定した第２挟持部材Ａ２がシリンダ本体Ａ３１側、すなわち第１挟持部材Ａ１に近付く方向にスライド移動する。そして、第２挟持部材Ａ２が横桟Ｗ１に当接する位置までシリンダロッドＡ３２を後退させ、さらにエアシリンダＡ３を引き込み駆動状態に維持し続ける。ここで、上述したように外縦桟Ｗ２を位置決め挟持機構（第２外縦桟挟持機構Ｃ）で挟持することにより型枠Ｋ全体は搬送フレームＧに対して移動不能な状態であるため、横桟Ｗ１に当接した第２挟持部材Ａ２がそれ以上第１挟持部材Ａ１に近付く方向へスライド移動することはできない。したがって、第２挟持部材Ａ２が横桟Ｗ１に当接した後もエアシリンダＡ３を引き込み駆動状態に維持し続けてシリンダロッドＡ３２をさらに後退させる（引き込ませる）と、第１挟持部材Ａ１が第２挟持部材Ａ２に近付く方向にスライド移動する。すると、間もなく第１挟持部材Ａ１が横桟Ｗ１に当接し、搬送方向Ｖ下流側の横桟挟持機構Ａは、一対の挟持部材（第１挟持部材Ａ１、第２挟持部材Ａ２）によって横桟Ｗ１を厚み方向から挟み込んだ挟み込み状態（Ｚ）になる（図１０及び図１１参照）。また、本実施形態では、第１挟持部材Ａ１に設けた滑り止め用鋲Ａ５が横桟Ｗ１に突き刺さるため、第１挟持部材Ａ１と第２挟持部材Ａ２との間に一旦挟み込んだ横桟Ｗ１は、シリンダロッドＡ３２を引き込み駆動状態から突出駆動状態に切り替えない限り、横桟Ｗ１に対して外力が作用した場合であっても挟み込み状態（Ｚ）を維持することが可能である。また、各挟持部材（第１挟持部材Ａ１、第２挟持部材Ａ２）はガイド軸Ａ７に沿ってスライド移動するため、スムーズ且つ安定した動作になる。 Moreover, the operation | movement and effect | action which the horizontal beam clamping mechanism A of the conveyance direction V downstream changes from an open state (Y) to a clamping state (Z) are as follows. First, the horizontal beam clamping mechanism A on the downstream side in the conveyance direction V is set to the open state (Y), and the horizontal beam W1 on the downstream side in the conveyance direction V is positioned between the first clamping member A1 and the second clamping member A2. In this state, when the air cylinder A3 is pulled and driven, the second clamping member A2 fixed to the tip of the cylinder rod A32 slides in the direction of approaching the cylinder body A31, that is, the first clamping member A1. Then, the cylinder rod A32 is retracted to a position where the second clamping member A2 comes into contact with the horizontal rail W1, and the air cylinder A3 is further retracted and maintained in the driving state. Here, as described above, the entire formwork K is incapable of moving with respect to the transport frame G by holding the outer vertical beam W2 by the positioning and holding mechanism (second outer vertical beam holding mechanism C). The second clamping member A2 in contact with the crosspiece W1 cannot slide further in the direction approaching the first clamping member A1. Accordingly, even after the second clamping member A2 comes into contact with the crosspiece W1, if the cylinder rod A32 is further retracted (retracted) while the air cylinder A3 is kept pulled and maintained in the driving state, the first clamping member A1 is the second clamping member A1. It slides in a direction approaching the clamping member A2. Then, soon the first clamping member A1 comes into contact with the horizontal beam W1, and the horizontal beam clamping mechanism A on the downstream side in the transport direction V is moved to the horizontal beam W1 by the pair of clamping members (first clamping member A1, second clamping member A2). Is sandwiched from the thickness direction (Z) (see FIGS. 10 and 11). In the present embodiment, since the anti-skid rod A5 provided on the first clamping member A1 pierces the horizontal rail W1, the horizontal rail W1 once sandwiched between the first clamping member A1 and the second clamping member A2 is As long as the cylinder rod A32 is not switched from the retracted drive state to the projecting drive state, it is possible to maintain the pinched state (Z) even when an external force is applied to the crosspiece W1. Further, since each clamping member (the first clamping member A1 and the second clamping member A2) slides along the guide axis A7, the operation is smooth and stable.
また、第１外縦桟挟持機構Ｂが開放状態（Ｙ）から挟み込み状態（Ｚ）に切り替わる動作及び作用は以下の通りである。先ず、第１外縦桟挟持機構Ｂを開放状態（Ｙ）に設定し、第１挟持部材Ｂ１と第２挟持部材Ｂ２との間に外縦桟Ｗ２を位置付けた状態で、エアシリンダＢ３を引き込み駆動状態にすると、シリンダロッドＢ３２の先端部に固定した第２挟持部材Ｂ２がシリンダ本体Ｂ３１側、すなわち第１挟持部材Ｂ１に近付く方向にスライド移動する。そして、第２挟持部材Ｂ２が外縦桟Ｗ２に当接する位置までシリンダロッドＢ３２を後退させ、さらにエアシリンダＢ３を引き込み駆動状態に維持し続けると、外縦桟Ｗ２に当接している第２挟持部材Ｂ２がそれ以上第１挟持部材Ｂ１に近付く方向へスライド移動することは規制され、シリンダロッドＢ３２の後退移動（引き込む方向への移動）により第１挟持部材Ｂ１が第２挟持部材Ｂ２に近付く方向にスライド移動する。すると、やがて第１挟持部材Ｂ１が外縦桟Ｗ２に当接し、第１外縦桟挟持機構Ｂは、一対の挟持部材（第１挟持部材Ｂ１、第２挟持部材Ｂ２）によって外縦桟Ｗ２を厚み方向から挟み込んだ挟み込み状態（Ｚ）になる（図１５参照）。また、第１外縦桟挟持機構Ｂのうち搬送方向Ｖ下流側の第１挟持部材Ｂ１と第２挟持部材Ｂ２とによって、外縦桟Ｗ２における搬送方向Ｖ下流側の端部を挟持した場合、枠材Ｗのうち搬送方向Ｖ下流側の横桟Ｗ１は、第２挟持部材Ｂ２に形成した切欠部Ｂｋに当接又は近接することにより、この横桟Ｗ１が第２挟持部材Ｂ２に干渉することを回避することができる（図１５参照）。また、本実施形態では、第１挟持部材Ｂ１に設けた滑り止め用鋲Ｂ５が外縦桟Ｗ２に突き刺さるため、第１挟持部材Ｂ１と第２挟持部材Ｂ２との間に外縦桟Ｗ２を強固に挟み込むことができる。さらに、第１挟持部材Ｂ１及び第２挟持部材Ｂ２はガイド軸Ｂ７に沿ってスムーズ且つ安定した状態でスライド移動する。 Moreover, the operation | movement and effect | action which the 1st outer vertical beam clamping mechanism B switches from an open state (Y) to a clamping state (Z) are as follows. First, the first outer vertical beam clamping mechanism B is set to the open state (Y), and the air cylinder B3 is pulled in with the outer vertical beam W2 positioned between the first clamping member B1 and the second clamping member B2. In the driving state, the second clamping member B2 fixed to the tip of the cylinder rod B32 slides in the direction of approaching the cylinder body B31, that is, the first clamping member B1. Then, when the cylinder rod B32 is retracted to a position where the second clamping member B2 comes into contact with the outer vertical beam W2, and the air cylinder B3 is continuously pulled in and maintained in the driven state, the second clamping member that is in contact with the outer vertical beam W2 The further sliding movement of the member B2 in the direction approaching the first clamping member B1 is restricted, and the direction in which the first clamping member B1 approaches the second clamping member B2 by the backward movement (movement in the retracting direction) of the cylinder rod B32. Move to slide. Then, the first clamping member B1 eventually comes into contact with the outer vertical beam W2, and the first outer vertical beam clamping mechanism B moves the outer vertical beam W2 by a pair of clamping members (first clamping member B1, second clamping member B2). The sandwiched state (Z) is sandwiched from the thickness direction (see FIG. 15). Further, when the end portion of the outer vertical rail W2 on the downstream side in the transport direction V is clamped by the first clamping member B1 and the second clamping member B2 on the downstream side in the transport direction V in the first outer vertical rail clamping mechanism B, The horizontal beam W1 on the downstream side in the conveying direction V in the frame material W abuts or approaches the notch Bk formed in the second clamping member B2, and this horizontal beam W1 interferes with the second clamping member B2. Can be avoided (see FIG. 15). In the present embodiment, since the anti-skid rod B5 provided on the first clamping member B1 pierces the outer vertical beam W2, the outer vertical beam W2 is firmly fixed between the first clamping member B1 and the second clamping member B2. Can be pinched. Further, the first clamping member B1 and the second clamping member B2 slide and move along the guide shaft B7 in a smooth and stable state.
また、各中間縦桟挟持機構Ｄが開放状態（Ｙ）から挟み込み状態（Ｚ）に切り替わる動作及び作用は以下の通りである。先ず、各中間縦桟挟持機構Ｄを開放状態（Ｙ）に設定し、第１挟持部材Ｄ１と第２挟持部材Ｄ２との間にそれぞれ中間縦桟Ｗ３を位置付けた状態で、エアシリンダＤ３を引き込み駆動状態にすると、シリンダロッドＤ３２の先端部に固定した第２挟持部材Ｄ２がシリンダ本体Ｄ３１側、すなわち第１挟持部材Ｄ１に近付く方向にスライド移動する。そして、第２挟持部材Ｄ２が外縦桟Ｗ２に当接する位置までシリンダロッドＤ３２を後退させ、さらにエアシリンダＤ３を引き込み駆動状態に維持し続けると、中間縦桟Ｗ３に当接している第２挟持部材Ｄ２の第１挟持部材Ｄ１側へのスライド移動が規制され、シリンダロッドＤ３２の後退移動により第１挟持部材Ｄ１が第２挟持部材Ｄ２に近付く方向にスライド移動する。すると、間もなく第１挟持部材Ｄ１が中間縦桟Ｗ３に当接し、中間縦桟挟持機構Ｄは、一対の挟持部材（第１挟持部材Ｄ１、第２挟持部材Ｄ２）によって外縦桟Ｗ２を厚み方向から挟み込んだ挟み込み状態（Ｚ）になる（図２１参照）。なお、滑り止め用鋲Ｄ５が外縦桟Ｗ２に突き刺さることにより、第１挟持部材Ｄ１と第２挟持部材Ｄ２との間に中間縦桟Ｗ３を強固に挟み込むことができる点、及び第１挟持部材Ｄ１及び第２挟持部材Ｄ２をガイド軸Ｄ７に沿ってスムーズ且つ安定した状態でスライド移動させることができる点は、上述した各挟持機構と同様である。 Moreover, the operation | movement and effect | action which each intermediate | middle vertical beam clamping mechanism D switches from an open state (Y) to a clamping state (Z) are as follows. First, each intermediate vertical beam clamping mechanism D is set to an open state (Y), and the air cylinder D3 is pulled in with the intermediate vertical beam W3 positioned between the first clamping member D1 and the second clamping member D2. When in the driving state, the second clamping member D2 fixed to the tip of the cylinder rod D32 slides in the direction of approaching the cylinder body D31, that is, the first clamping member D1. Then, when the cylinder rod D32 is retracted to a position where the second clamping member D2 comes into contact with the outer vertical beam W2, and the air cylinder D3 is further pulled in and maintained in the driven state, the second clamping member that is in contact with the intermediate vertical beam W3. The sliding movement of the member D2 toward the first clamping member D1 is restricted, and the first clamping member D1 slides in the direction approaching the second clamping member D2 due to the backward movement of the cylinder rod D32. Then, soon the first clamping member D1 comes into contact with the intermediate vertical beam W3, and the intermediate vertical beam clamping mechanism D moves the outer vertical beam W2 in the thickness direction by a pair of clamping members (first clamping member D1, second clamping member D2). The sandwiched state (Z) is sandwiched (see FIG. 21). It should be noted that the intermediate vertical beam W3 can be firmly sandwiched between the first clamping member D1 and the second clamping member D2 by the anti-skid rod D5 being pierced into the outer vertical beam W2, and the first clamping member The point that D1 and the second clamping member D2 can be slid and moved along the guide axis D7 in a smooth and stable manner is the same as that of each clamping mechanism described above.
本実施形態に係る型枠分解装置Ｘは、位置決め手段として機能する第２外縦桟挟持機構Ｃ以外の挟持機構（横桟挟持機構Ａ、第１外縦桟挟持機構Ｂ、中間縦桟挟持機構Ｄ）における第１挟持部材Ａ１及び第２挟持部材Ａ２（第１挟持部材Ａ１及び第２挟持部材Ａ２、第１挟持部材Ｂ１及び第２挟持部材Ｂ２、第１挟持部材Ｄ１及び第２挟持部材Ｄ２）を何れも相対する挟持部材に対して接離動作可能に構成している。これにより、型枠Ｋごとに、幅方向に隣り合う縦桟（外縦桟Ｗ２、中間縦桟Ｗ３）同士間のピッチや各桟（外縦桟Ｗ２、中間縦桟Ｗ３、横桟Ｗ１）の厚み寸法に多少の誤差が生じていても、各挟持機構単位で、第１挟持部材及び第２挟持部材のスライド移動距離が、挟む対象の桟を基準にして自動的に変更し、各桟を厚み方向の両側面から均等ないしほぼ均等に押圧した状態で強固に挟持することができる。これにより、桟の厚み方向の両側面から不均等な押圧力が作用した場合に生じる不具合、すなわち、桟をへし折る方向への押圧力が桟に作用することによって桟が変形或いは破損することを防止できる。 The formwork disassembling apparatus X according to this embodiment includes a clamping mechanism (a horizontal beam clamping mechanism A, a first outer vertical beam clamping mechanism B, an intermediate vertical beam clamping mechanism) other than the second outer vertical beam clamping mechanism C functioning as positioning means. D) The first clamping member A1 and the second clamping member A2 (the first clamping member A1 and the second clamping member A2, the first clamping member B1 and the second clamping member B2, the first clamping member D1 and the second clamping member D2). ) Are configured to be capable of moving toward and away from the opposing clamping member. As a result, for each formwork K, the pitch between the vertical bars (outer vertical bars W2, intermediate vertical bars W3) adjacent in the width direction and the widths of the bars (outer vertical bars W2, intermediate vertical bars W3, horizontal bars W1). Even if there is some error in the thickness dimension, the sliding movement distance of the first clamping member and the second clamping member is automatically changed on the basis of the target object to be sandwiched for each holding mechanism unit. It can be firmly held in a state where it is pressed evenly or substantially uniformly from both side surfaces in the thickness direction. This prevents problems that occur when uneven pressing force is applied from both sides in the thickness direction of the crosspiece, that is, the crosspiece is prevented from being deformed or damaged due to the pressing force in the direction of folding the crosspiece acting on the crosspiece. it can.
上述した実施形態は、各挟持機構（横桟挟持機構Ａ、第１外縦桟挟持機構Ｂ、第２外縦桟挟持機構Ｃ、中間縦桟挟持機構Ｄ）の開放状態（Ｙ）から挟み込み状態（Ｚ）への切替を同時ないしほぼ同時に行う態様を例示したが、位置決め手段として機能する挟持機構（第２外縦桟挟持機構Ｃ）を開放状態（Ｙ）から挟み込み状態（Ｚ）へ切り替えた後に、残りの挟持機構（横桟挟持機構Ａ、第１外縦桟挟持機構Ｂ、中間縦桟挟持機構Ｄ）を順次或いは同時ないしほぼ同時に開放状態（Ｙ）から挟み込み状態（Ｚ）へ切り替えるように構成しても構わない。また、上下動機構Ｆによる横桟挟持機構Ａの上方への移動を、第２外縦桟挟持機構Ｃによって外縦桟Ｗ２を挟持した後に行うようにしてもよい。 In the embodiment described above, each clamping mechanism (horizontal beam clamping mechanism A, first outer vertical beam clamping mechanism B, second outer vertical beam clamping mechanism C, intermediate vertical beam clamping mechanism D) is clamped from the open state (Y). The mode of switching to (Z) is illustrated at the same time or almost simultaneously, but the clamping mechanism (second outer vertical beam clamping mechanism C) functioning as the positioning means is switched from the open state (Y) to the sandwiched state (Z). Later, the remaining clamping mechanisms (horizontal beam clamping mechanism A, first outer vertical beam clamping mechanism B, intermediate vertical beam clamping mechanism D) are switched from the open state (Y) to the sandwiched state (Z) sequentially or simultaneously or almost simultaneously. You may comprise. Further, the upward movement of the horizontal beam clamping mechanism A by the vertical movement mechanism F may be performed after the outer vertical beam W2 is clamped by the second outer vertical beam clamping mechanism C.
そして、各挟持機構（搬送方向Ｖ下流側の横桟挟持機構Ａ、第１外縦桟挟持機構Ｂ、第２外縦桟挟持機構Ｃ、中間縦桟挟持機構Ｄ）により枠材Ｗの各桟（搬送方向Ｖ下流側の横桟Ｗ１、外縦桟Ｗ２、中間縦桟Ｗ３）をそれぞれ厚み方向から挟持した状態で、押し上げ機構Ｅによりパネル板Ｐを枠材Ｗから離間する方向に押し上げる。具体的には、シリンダ本体Ｅ２１内へ作動油（圧油）を供給し、先端部を押し上げプレートＥ１に連結したシリンダロッドＥ２２を上方へ突出させて、押し上げプレートＥ１をパネル板Ｐの下向き面に押し当てて、さらに、シリンダロッドＥ２２を上方へ突出させることにより、押し上げプレートＥ１がパネル板Ｐを押し上げながら上方へ移動する。その結果、パネル板Ｐが枠材Ｗから浮き上がり、所定距離浮き上がると固定具Ｎ（釘）によるパネル板Ｐと枠材Ｗとの固定状態が解除され（すなわち、枠材Ｗから釘Ｎが抜け）、押し上げられたパネル板Ｐが枠材Ｗに対してフリーな状態になる（図２２参照）。なお、図９、図１１、図１２、図２２では、外縦桟Ｗ２を挟持する外縦桟機構（第１外縦桟挟持機構Ｂ、第２外縦桟挟持機構Ｃ）を省略している。本実施形態の型枠分解装置Ｘは、図５及び図６に示すように、隣り合う縦桟（外縦桟Ｗ２、中間縦桟Ｗ３）同士の間にそれぞれ押し上げ機構Ｅを設けているため、これら複数の押し上げ機構Ｅを同期させて駆動させることによりパネル板Ｐの幅方向全体に均等ないしほぼ均等な押し上げ力を作用させて枠材Ｗから浮き上がらせることができる。また、シリンダロッドＥ２２の先端部に押し上げプレートＥ１を水平軸Ｅ３回りに揺動可能に連結しているため、押し上げ機構Ｅによってパネル板Ｐを枠材Ｗから浮き上がらせる過程でパネル板Ｐが反る方向に撓み変形した場合であっても、パネル板Ｐの変形量に応じて押し上げプレートＥ１が適宜揺動することにより押し上げプレートＥ１全体ないしほぼ全体をパネル板Ｐの下向き面に接触させて押し上げることができる。 Then, each frame of the frame member W is supported by each clamping mechanism (the horizontal beam clamping mechanism A, the first outer vertical beam clamping mechanism B, the second outer vertical beam clamping mechanism C, and the intermediate vertical beam clamping mechanism D on the downstream side in the transport direction V). The panel plate P is pushed up in the direction away from the frame material W by the push-up mechanism E in a state where the horizontal beam W1, the outer vertical beam W2, and the intermediate vertical beam W3 on the downstream side in the conveying direction V are sandwiched from the thickness direction. Specifically, hydraulic oil (pressure oil) is supplied into the cylinder body E21, and the cylinder rod E22 with its tip portion connected to the push-up plate E1 is protruded upward, so that the push-up plate E1 faces the downward surface of the panel plate P. By pushing and further projecting the cylinder rod E22 upward, the push-up plate E1 moves upward while pushing up the panel plate P. As a result, the panel plate P is lifted from the frame member W, and when the panel plate P is lifted by a predetermined distance, the fixed state of the panel plate P and the frame member W by the fixture N (nail) is released (that is, the nail N comes off from the frame member W). Then, the pushed-up panel plate P becomes free with respect to the frame member W (see FIG. 22). In FIG. 9, FIG. 11, FIG. 12, and FIG. 22, the outer vertical beam mechanisms (the first outer vertical beam clamping mechanism B and the second outer vertical beam clamping mechanism C) that clamp the outer vertical beam W2 are omitted. . As shown in FIGS. 5 and 6, the formwork disassembling apparatus X of the present embodiment is provided with a push-up mechanism E between adjacent vertical beams (outer vertical beam W2, intermediate vertical beam W3). By driving these plurality of push-up mechanisms E in synchronism with each other, a uniform or substantially uniform push-up force can be applied to the entire width direction of the panel plate P to lift it from the frame member W. Further, since the push-up plate E1 is connected to the tip of the cylinder rod E22 so as to be swingable around the horizontal axis E3, the panel plate P warps in the process of lifting the panel plate P from the frame material W by the push-up mechanism E. Even if it is bent and deformed in the direction, the push-up plate E1 is appropriately swung in accordance with the deformation amount of the panel plate P, so that the whole or almost the whole push-up plate E1 is brought into contact with the downward surface of the panel plate P and pushed up. Can do.
本実施形態では、第１外縦桟挟持機構Ｂ、第２外縦桟挟持機構Ｃ、及び中間縦桟挟持機構Ｄの全長を、枠材Ｗの外縦桟Ｗ２及び中間縦桟Ｗ３の全長よりも短く設定しているため、上記手順によって枠材Ｗから浮き上がってフリーになるパネル板Ｐは搬送方向Ｖ下流側の領域だけである。したがって、上記手順に準じた作業を複数回繰り返すことによってパネル板Ｐ全体を枠材Ｗから引き離すことができる。以下、その作業手順を説明する。 In the present embodiment, the total length of the first outer vertical beam clamping mechanism B, the second outer vertical beam clamping mechanism C, and the intermediate vertical beam clamping mechanism D is greater than the total length of the outer vertical beam W2 and the intermediate vertical beam W3 of the frame member W. Therefore, the panel plate P that is lifted from the frame member W and becomes free by the above procedure is only the region on the downstream side in the transport direction V. Therefore, the whole panel board P can be pulled away from the frame material W by repeating the operation | work according to the said procedure in multiple times. The work procedure will be described below.
押し上げ機構Ｅによってパネル板Ｐにおける搬送方向Ｖ下流側の領域を枠材Ｗから分離させた状態で、押し上げ機構Ｅによるパネル板Ｐの押し上げ状態を解除する。具体的には、シリンダ本体Ｅ２１内の作動油を排出し、先端部を押し上げプレートＥ１に連結したシリンダロッドＥ２２を下方へ引き込ませて、押し上げプレートＥ１を型枠Ｋの下端部（桟の下向き面）よりも下方へ移動させる。 With the push-up mechanism E separating the region on the downstream side in the transport direction V of the panel plate P from the frame material W, the push-up state of the panel plate P by the push-up mechanism E is released. Specifically, the hydraulic oil in the cylinder body E21 is discharged, and the cylinder rod E22 having the tip connected to the push-up plate E1 is pulled downward, so that the push-up plate E1 is moved to the lower end of the formwork K (the downward surface of the crosspiece). ) To move downward.
次に、各挟持機構（搬送方向Ｖ下流側の横桟挟持機構Ａ、第１外縦桟挟持機構Ｂ、第２外縦桟挟持機構Ｃ、中間縦桟Ｗ３機構）を挟み込み状態（Ｚ）から開放状態（Ｙ）に同時ないしほぼ同時に切り替える。なお、各挟持機構搬（搬送方向Ｖ下流側の横桟挟持機構Ａ、第１外縦桟挟持機構Ｂ、第２外縦桟挟持機構Ｃ、中間縦桟Ｗ３機構）を順次挟み込み状態（Ｚ）から開放状態（Ｙ）に切り替えるようにしてもよい。 Next, each clamping mechanism (the horizontal beam clamping mechanism A on the downstream side in the transport direction V, the first outer vertical beam clamping mechanism B, the second outer vertical beam clamping mechanism C, and the intermediate vertical beam W3 mechanism) from the clamping state (Z) Switch to the open state (Y) simultaneously or almost simultaneously. In addition, each clamping mechanism carrying (horizontal beam clamping mechanism A on the downstream side in the conveying direction V, first outer vertical beam clamping mechanism B, second outer vertical beam clamping mechanism C, intermediate vertical beam W3 mechanism) is sequentially clamped (Z). May be switched from the open state to the open state (Y).
ここで、挟み込み状態（Ｚ）から開放状態（Ｙ）へ切り替わる挟持機構の動作及び作用を搬送方向Ｖ下流側の横桟挟持機構Ａを例にして説明する。先ず、挟み込み状態（Ｚ）において、エアシリンダＡ３を、シリンダロッドＡ３２を突出動作させる（シリンダ本体Ａ３１側から前進させる）突出駆動状態に切り替える。すると、第１挟持部材Ａ１及び第２挟持部材Ａ２のうち滑り止め用鋲Ａ５を設けていない方の挟持部材（本実施形態の横桟挟持機構Ａであれば第２挟持部材Ａ２）が他方の挟持部材（第１挟持部材Ａ１）よりも優先して横桟Ｗ１から離間する方向にスライド移動する。なお、何れの挟持部材（第１挟持部材Ａ１、第２挟持部材Ａ２）にも滑り止め手段Ａ５（滑り止め用鋲Ａ５）を設けていない態様であれば、エアシリンダＡ３を突出駆動状態にするとエアシリンダＡ３の先端部に固定した挟持部材（第２挟持部材Ａ２）が他方の挟持部材（第１挟持部材Ａ１）よりも優先して横桟Ｗ１から離間する方向にスライド移動するが、本実施形態のように、挟挟み込み状態（Ｚ）において一方の挟持部材（第１挟持部材Ａ１）に設けた滑り止め用鋲Ａ５が横桟Ｗ１に突き刺さっているため、上述したように、第１挟持部材Ａ１及び第２挟持部材Ａ２のうち滑り止め用鋲Ａ５を設けていない方の挟持部材（本実施形態の横桟挟持機構Ａであれば第２挟持部材Ａ２）が他方の挟持部材よりも優先して横桟Ｗ１から離間する方向にスライド移動する。 Here, the operation and action of the clamping mechanism that switches from the clamping state (Z) to the open state (Y) will be described by taking the horizontal beam clamping mechanism A on the downstream side in the transport direction V as an example. First, in the pinching state (Z), the air cylinder A3 is switched to a projecting drive state in which the cylinder rod A32 is projected (moved forward from the cylinder body A31 side). Then, of the first clamping member A1 and the second clamping member A2, the clamping member that is not provided with the anti-slip rod A5 (the second clamping member A2 in the case of the horizontal rail clamping mechanism A of the present embodiment) is the other. It slides in a direction away from the crosspiece W1 with priority over the holding member (first holding member A1). If any of the clamping members (the first clamping member A1 and the second clamping member A2) is not provided with the anti-slip means A5 (anti-slip rod A5), the air cylinder A3 is set in the projecting drive state. The clamping member (second clamping member A2) fixed to the tip of the air cylinder A3 slides in a direction away from the crosspiece W1 in preference to the other clamping member (first clamping member A1). As described above, the anti-skid rod A5 provided on one of the clamping members (first clamping member A1) in the clamping state (Z) pierces the horizontal rail W1, so that the first clamping member as described above Of the A1 and the second clamping member A2, the clamping member that is not provided with the anti-slip rod A5 (the second clamping member A2 in the case of the horizontal rail clamping mechanism A of the present embodiment) has priority over the other clamping member. Away from the crosspiece W1 In the direction to slide.
そして、第２挟持部材Ａ２（滑り止め用鋲Ａ５を設けていない方の挟持部材）が、ベースＡ４上に設けたガイド軸受けＡ８に当接する位置までスライド移動すると、それ以上同一方向（横桟Ｗ１から離間する方向）へのスライド移動は規制される。さらにエアシリンダＡ３を突出駆動状態に維持し続けてシリンダロッドＡ３２をさらに前進させる（突出させる）と、第１挟持部材Ａ１が横桟Ｗ１から離間する方向にスライド移動する。これにより、横桟挟持機構Ａは開放状態（Ｙ）になる（図７及び図９参照）。なお、第１挟持部材Ａ１はベースＡ４上に設けたガイド軸受けＡ８に当接する位置までスライド移動する。このように、対をなすガイド軸受けＡ８は、ガイド軸Ａ７を支持するのみならず、第１挟持部材Ａ１及び第２挟持部材Ａ２のスライド移動幅を規定する部材として機能する。 Then, when the second clamping member A2 (the clamping member on which the anti-slip rod A5 is not provided) slides to a position where it abuts on the guide bearing A8 provided on the base A4, the same direction (the horizontal beam W1) Slide movement in a direction away from the head) is restricted. When the cylinder rod A32 is further moved forward (protruded) while the air cylinder A3 is kept in the projecting drive state, the first clamping member A1 slides in a direction away from the crosspiece W1. Thereby, the horizontal rail clamping mechanism A will be in an open state (Y) (refer FIG.7 and FIG.9). The first clamping member A1 slides to a position where it comes into contact with a guide bearing A8 provided on the base A4. Thus, the paired guide bearings A8 not only support the guide shaft A7, but also function as members that define the sliding movement width of the first clamping member A1 and the second clamping member A2.
以上のような作動により、全ての挟持機構（横桟挟持機構Ａ、第１外縦桟挟持機構Ｂ、第２外縦桟挟持機構Ｃ、中間縦桟挟持機構Ｄ）を挟み込み状態（Ｚ）から開放状態（Ｙ）に切り替えた後、上下動機構Ｆを駆動させて横桟挟持機構Ａを、横桟Ｗ１を挟持可能な高さ位置から横桟Ｗ１を挟持不可能な高さ位置に移動させる（図１２参照）。引き続いて、パネル板Ｐのうち固定具Ｎによる固定状態が維持されている領域が搬送フレームＧの長手方向中央領域まで到達する位置まで型枠Ｋを搬送方向Ｖ下流側に搬送する。この際、搬送フレームＧの搬送用ローラＧ１が回転することによって軽い力で型枠Ｋを搬送することができ、また、搬送フレームＧのガイドローラＧ４に外縦桟Ｗ２の内向き面を当てながらガイドさせることにより、型枠Ｋの搬送をスムーズ且つ適切に行うことができる。なお、型枠Ｋを搬送方向Ｖ下流側に押す操作力を付与することによって搬送用ローラＧ１が回転する態様、又は所定の操作部への操作に基づいて搬送用ローラＧ１を回転駆動させる態様、これら何れの態様であってもよい。 By the operation as described above, all the clamping mechanisms (the horizontal beam clamping mechanism A, the first outer vertical beam clamping mechanism B, the second outer vertical beam clamping mechanism C, and the intermediate vertical beam clamping mechanism D) are held from the clamping state (Z). After switching to the open state (Y), the vertical movement mechanism F is driven to move the horizontal beam clamping mechanism A from a height position at which the horizontal beam W1 can be clamped to a height position at which the horizontal beam W1 cannot be clamped. (See FIG. 12). Subsequently, the mold K is transported downstream in the transport direction V to the position where the region of the panel plate P that is fixed by the fixture N reaches the center region in the longitudinal direction of the transport frame G. At this time, the conveyance roller G1 of the conveyance frame G is rotated so that the mold K can be conveyed with a light force, and the inward surface of the outer vertical rail W2 is applied to the guide roller G4 of the conveyance frame G. By guiding, the form K can be transported smoothly and appropriately. A mode in which the transport roller G1 rotates by applying an operation force that pushes the formwork K downstream in the transport direction V, or a mode in which the transport roller G1 is driven to rotate based on an operation to a predetermined operation unit, Any of these embodiments may be used.
そして、各挟持機構（横桟挟持機構Ａ、第１外縦桟挟持機構Ｂ、第２外縦桟挟持機構Ｃ、中間縦桟挟持機構Ｄ）を開放状態（Ｙ）から挟み込み状態（Ｚ）に切り替えて、第１外縦桟挟持機構Ｂ、第２外縦桟挟持機構Ｃ、中間縦桟挟持機構Ｄによって外縦桟Ｗ２及び中間縦桟Ｗ３をそれぞれ挟持して固定した状態で、押し上げ機構Ｅによりパネル板Ｐを枠材Ｗから離間する方向に押し上げると、パネル板Ｐのうち各挟持機構（第１外縦桟挟持機構Ｂ、第２外縦桟挟持機構Ｃ、中間縦桟挟持機構Ｄ）の全長に相当する領域で釘Ｎによる枠材Ｗとの固定状態が解除される。 Then, each clamping mechanism (horizontal beam clamping mechanism A, first outer vertical beam clamping mechanism B, second outer vertical beam clamping mechanism C, intermediate vertical beam clamping mechanism D) is changed from the open state (Y) to the sandwiched state (Z). In the state where the outer vertical beam W2 and the intermediate vertical beam W3 are clamped and fixed by the first outer vertical beam clamping mechanism B, the second outer vertical beam clamping mechanism C, and the intermediate vertical beam clamping mechanism D, respectively, the push-up mechanism E When the panel plate P is pushed up in the direction away from the frame material W, each clamping mechanism (first outer vertical beam clamping mechanism B, second outer vertical beam clamping mechanism C, intermediate vertical beam clamping mechanism D) of the panel plate P is pushed. The fixed state with the frame material W by the nail N is released in a region corresponding to the total length of the.
このように、パネル板Ｐの全長に応じて、上記手順、つまり第１外縦桟挟持機構Ｂ、第２外縦桟挟持機構Ｃ、中間縦桟挟持機構Ｄによって外縦桟Ｗ２、中間縦桟Ｗ３を挟持するステップ、押し上げ機構Ｅによりパネル板Ｐを押し上げるステップ、押し上げ機構Ｅによるパネル板Ｐの押し上げ状態を解除する（押し上げプレートＥ１を下げる）ステップ、第１外縦桟挟持機構Ｂ、第２外縦桟挟持機構Ｃ、中間縦桟挟持機構Ｄによる外縦桟Ｗ２、中間縦桟Ｗ３の挟持状態を解除するステップ、型枠Ｋを搬送方向Ｖ下流側に搬送するステップを繰り返す。 Thus, according to the total length of the panel plate P, the above-described procedure, that is, the first outer vertical beam clamping mechanism B, the second outer vertical beam clamping mechanism C, and the intermediate vertical beam clamping mechanism D are used. A step of sandwiching W3, a step of pushing up the panel plate P by the push-up mechanism E, a step of releasing the push-up state of the panel plate P by the push-up mechanism E (lowering the push-up plate E1), a first outer vertical beam clamping mechanism B, a second The step of releasing the clamping state of the outer vertical beam W2 and the intermediate vertical beam W3 by the outer vertical beam clamping mechanism C, the intermediate vertical beam clamping mechanism D, and the step of conveying the mold K downstream in the conveying direction V are repeated.
そして、最後にパネル板Ｐのうち搬送方向Ｖ上流側の領域を枠材Ｗから引き離す際は、型枠Ｋのうち搬送方向Ｖ上流側の横桟Ｗ１が平面視において搬送方向Ｖ上流側の横桟挟持機構Ａにおける第１挟持部材Ａ１と第２挟持部材Ａ２との間に位置付けられるように型枠Ｋを搬送フレームＧ上にセットする。本実施形態では、予め開放状態（Ｙ）に設定した第２外縦桟挟持機構Ｃのうち搬送方向Ｖ上流側の第２挟持部材Ｃ２に形成した切欠部Ｃｋに、枠材Ｗのうち搬送方向Ｖ上流側の横桟Ｗ１を押し当てることによって、搬送方向Ｖ上流側の横桟Ｗ１が平面視において搬送方向Ｖ上流側の横桟挟持機構Ａにおける第１挟持部材Ａ１と第２挟持部材Ａ２との間に位置付けることができるように設定している。また、第２挟持部材Ｃ２に形成した切欠部Ｃｋに、枠材Ｗのうち搬送方向Ｖ上流側の横桟Ｗ１を接触させる（押し当てる）とともに、第２外縦桟挟持機構Ｃにおける第２挟持部材Ｃ２のうち第１挟持部材Ｃ１に対向する面に外縦桟Ｗ２を接触させる（押し当てる）ことによって、枠材Ｗの四隅のうち一つの隅部（コーナー部）を第２外縦桟挟持機構Ｃの一部（本実施形態では第２挟持部材Ｃ２）に緊密ないしほぼ緊密に当接させることができる。 Finally, when the region of the panel plate P on the upstream side in the transport direction V is pulled away from the frame member W, the horizontal beam W1 on the upstream side in the transport direction V of the mold K is laterally located on the upstream side in the transport direction V in plan view. The mold K is set on the transport frame G so as to be positioned between the first clamping member A1 and the second clamping member A2 in the beam clamping mechanism A. In the present embodiment, in the second outer vertical beam clamping mechanism C set in the open state (Y) in advance, in the notch Ck formed in the second clamping member C2 on the upstream side in the conveyance direction V, in the conveyance direction in the frame material W. By pressing the horizontal beam W1 on the upstream side of the V, the horizontal beam W1 on the upstream side in the transport direction V in the plan view, the first clamping member A1 and the second clamping member A2 in the horizontal beam clamping mechanism A on the upstream side in the conveyance direction V It is set so that it can be positioned between. In addition, the horizontal beam W1 on the upstream side in the conveying direction V of the frame material W is brought into contact with (not pressed to) the notch Ck formed in the second clamping member C2, and the second clamping in the second outer vertical beam clamping mechanism C is performed. One of the four corners (corner portion) of the frame member W is clamped by bringing the outer vertical beam W2 into contact with (pressing) the surface of the member C2 facing the first clamping member C1. It can be brought into close contact or almost tight contact with a part of the mechanism C (second holding member C2 in this embodiment).
そして、図２３に示すように、上下動機構Ｆを駆動させて搬送方向Ｖ上流側の横桟挟持機構Ａを、横桟Ｗ１を挟持不可能な高さ位置から横桟Ｗ１を挟持可能な高さ位置に移動させて、搬送方向Ｖ上流側の横桟挟持機構Ａ、第１外縦桟挟持機構Ｂ、第２外縦桟挟持機構Ｃ、中間縦桟挟持機構Ｄによって搬送方向Ｖ上流側の横桟Ｗ１、外縦桟Ｗ２、中間縦桟Ｗ３をそれぞれ挟持する。この際、第１外縦桟挟持機構Ｂのうち搬送方向Ｖ上流側の第１挟持部材Ｂ１と第２挟持部材Ｂ２とによって、外縦桟Ｗ２の搬送方向Ｖ上流側端部を挟持した場合、枠材Ｗのうち搬送方向Ｖ上流側の横桟Ｗ１は、第２挟持部材Ｂ２に形成した切欠部Ｂｋに当接又は近接することにより、この横桟Ｗ１が第２挟持部材Ｂ２に干渉することを回避することができる。なお、上下動機構Ｆを駆動させるタイミング及び操作は、上述した通り、作業者自身の判断に基づくタイミング及び作業者自身による操作であってもよいが、本実施形態に係る型枠分解装置Ｘでは、図１７に示すように、型枠Ｋの搬送方向Ｖ上流端（型枠Ｋの後尾）を検知する位置検知手段Ｓ２を所定箇所に設け、この位置検知手段Ｓ２によって型枠Ｋの搬送方向Ｖ上流端を検知した場合に、上下動機構Ｆを作動させて搬送方向Ｖ上流側の横桟挟持機構Ａが横桟Ｗ１を挟持不可能な高さ位置から横桟Ｗ１を挟持可能な高さ位置に自動的に移動するように構成している。位置検知手段Ｓ２としては、例えばリミットスイッチや近接スイッチ等が挙げられ、このような位置検知手段Ｓ２を、外縦桟挟持機構（例えば第２外縦桟挟持機構Ｃ）における搬送方向Ｖ上流側の端部に設けている。 Then, as shown in FIG. 23, the vertical movement mechanism F is driven to move the horizontal beam clamping mechanism A on the upstream side in the transport direction V from the height position where the horizontal beam W1 cannot be clamped. To the vertical position, the horizontal beam clamping mechanism A on the upstream side in the conveyance direction V, the first outer vertical beam clamping mechanism B, the second outer vertical beam clamping mechanism C, and the intermediate vertical beam clamping mechanism D The horizontal beam W1, the outer vertical beam W2, and the intermediate vertical beam W3 are respectively clamped. At this time, when the end portion of the outer vertical beam W2 in the conveying direction V upstream side is clamped by the first clamping member B1 and the second clamping member B2 on the upstream side in the conveying direction V of the first outer vertical beam clamping mechanism B, The horizontal beam W1 on the upstream side in the conveying direction V in the frame material W abuts or approaches the notch Bk formed in the second clamping member B2, and this horizontal beam W1 interferes with the second clamping member B2. Can be avoided. As described above, the timing and operation for driving the vertical movement mechanism F may be timing based on the operator's own judgment and operation by the operator himself, but in the formwork disassembling apparatus X according to the present embodiment, As shown in FIG. 17, position detection means S2 for detecting the upstream end (the rear end of the mold K) in the conveyance direction V of the mold K is provided at a predetermined location, and the conveyance direction V of the mold K is detected by the position detection means S2. When the upstream end is detected, the vertical movement mechanism F is operated, and the height position at which the horizontal beam sandwiching mechanism A on the upstream side in the transport direction V cannot clamp the horizontal beam W1 from the height position at which the horizontal beam W1 can be clamped. It is configured to move automatically. Examples of the position detection unit S2 include a limit switch and a proximity switch. The position detection unit S2 is arranged on the upstream side in the transport direction V in the outer vertical beam clamping mechanism (for example, the second outer vertical beam clamping mechanism C). It is provided at the end.
そして、各挟持機構（搬送方向Ｖ上流側の横桟挟持機構Ａ、第１外縦桟挟持機構Ｂ、第２外縦桟挟持機構Ｃ、中間縦桟挟持機構Ｄ）により枠材Ｗの各桟（搬送方向Ｖ上流側の横桟Ｗ１、外縦桟Ｗ２、中間縦桟Ｗ３）をそれぞれ厚み方向から挟持した状態で、押し上げ機構Ｅによりパネル板Ｐを枠材Ｗから離間する方向に押し上げることによって、パネル板Ｐが枠材Ｗから浮き上がり、釘Ｎによるパネル板Ｐと枠材Ｗとの固定状態が解除され（すなわち、枠材Ｗから釘Ｎが抜け）、パネル板Ｐが枠材Ｗに対して完全にフリーな状態になる（図２３参照）。 Then, each frame of the frame material W is supported by each clamping mechanism (the horizontal beam clamping mechanism A, the first outer vertical beam clamping mechanism B, the second outer vertical beam clamping mechanism C, and the intermediate vertical beam clamping mechanism D on the upstream side in the transport direction V). By pushing up the panel plate P in a direction away from the frame material W by the push-up mechanism E in a state where the horizontal beam W1, the outer vertical beam W2, and the intermediate vertical beam W3 on the upstream side in the conveying direction V are sandwiched from each other in the thickness direction. The panel plate P is lifted from the frame member W, the fixed state of the panel plate P and the frame member W by the nail N is released (that is, the nail N is removed from the frame member W), and the panel plate P is moved with respect to the frame member W. And completely free (see FIG. 23).
以上の手順により、固定具Ｎを付帯したパネル板Ｐを枠材Ｗから完全に取り外すことができる。なお、各挟持機構（横桟挟持機構Ａ、第１外縦桟挟持機構Ｂ、第２外縦桟挟持機構Ｃ、中間縦桟挟持機構Ｄ）を開放状態（Ｙ）と挟み込み状態（Ｚ）との間で切り替える操作や、押し上げ機構Ｅを作動させて押し上げプレートＥ１の高さ位置を変更する操作は、所定箇所に設けた操作ボタンや操作レバー等の操作部に対して所定の操作力を付与することによって行うことができる。また、各挟持機構（横桟挟持機構Ａ、第１外縦桟挟持機構Ｂ、第２外縦桟挟持機構Ｃ、中間縦桟挟持機構Ｄ）を作動させる操作部、及び押し上げ機構Ｅを作動させる操作部をそれぞれ両手で同時に操作可能な位置に配置し、本実施形態に係る型枠分解装置Ｘによる型枠Ｋの分解作業中（当該実施形態では型枠Ｋを搬送フレームＧの長手方向に搬送する工程を除く）は両手を常に操作部に置くように誘導することにより、分解作業中に手が挟持機構（横桟挟持機構Ａ、第１外縦桟挟持機構Ｂ、第２外縦桟挟持機構Ｃ、中間縦桟挟持機構Ｄ）や押し上げ機構Ｅに不意に接触することを防止している。また、操作部を作業者の足下に配置していない点も安全性向上に資する。 With the above procedure, the panel plate P with the fixture N can be completely removed from the frame material W. Each clamping mechanism (horizontal beam clamping mechanism A, first outer vertical beam clamping mechanism B, second outer vertical beam clamping mechanism C, intermediate vertical beam clamping mechanism D) is in an open state (Y) and a sandwiched state (Z). And the operation of changing the height position of the push-up plate E1 by applying the push-up mechanism E gives a predetermined operation force to operation portions such as operation buttons and operation levers provided at predetermined positions. Can be done. In addition, the operation unit for operating each clamping mechanism (the horizontal beam clamping mechanism A, the first outer vertical beam clamping mechanism B, the second outer vertical beam clamping mechanism C, the intermediate vertical beam clamping mechanism D), and the push-up mechanism E are activated. The operation unit is disposed at a position where it can be operated with both hands at the same time, and the mold K is being disassembled by the mold disassembling apparatus X according to the present embodiment (in this embodiment, the mold K is transported in the longitudinal direction of the transport frame G). (Except for the step of performing), the hands are always placed on the operation section, so that the hand can pinch the mechanism during the disassembly work (horizontal beam clamping mechanism A, first outer vertical beam clamping mechanism B, second outer vertical beam clamping) Inadvertent contact with the mechanism C, the intermediate vertical beam clamping mechanism D) and the push-up mechanism E is prevented. Moreover, the point which has not arrange | positioned the operation part under a worker's foot also contributes to safety improvement.
なお、本実施形態に係る型枠分解装置Ｘによって枠材Ｗから引き離したパネル板Ｐには釘Ｎが刺さり、釘Ｎの胴部及び先端部が下方に突出した状態となっているが、この釘Ｎは別途適宜の工具等を用いてパネル板Ｐから除去すればよい。 The panel plate P separated from the frame material W by the mold disassembling apparatus X according to the present embodiment is pierced by the nail N, and the body portion and the tip portion of the nail N protrude downward. The nail N may be removed from the panel plate P using an appropriate tool or the like.
そして、それぞれ分解したパネル板Ｐ及び枠材Ｗは再度型枠Ｋとして、或いは型枠Ｋ以外の用途に再利用することが可能となる。 Then, the disassembled panel plate P and frame material W can be reused as the mold K again or for uses other than the mold K.
このように、本実施形態に係る型枠分解装置Ｘは、各挟持機構（横桟挟持機構Ａ、第１外縦桟挟持機構Ｂ、第２外縦桟挟持機構Ｃ、中間縦桟挟持機構Ｄ）によって枠材Ｗの桟（横桟Ｗ１、外縦桟Ｗ２、中間縦桟Ｗ３）を挟持した状態で押し上げ機構Ｅによりパネル板Ｐを枠材Ｗから引き離す方向に押し上げるように構成しているため、例えば各釘Ｎの周辺部位を刳り抜いて枠材Ｗとパネル板Ｐとを分解する態様と比較して、各型枠Ｋごとに釘Ｎの打ち込み箇所が多少異なっていても、パネル板Ｐ自体を枠材Ｗから引き離す方向へ押し上げることにより固定具Ｎ（釘）による枠材Ｗとパネル板Ｐとの固定状態を解除することができ、作業効率が格段に向上する。 As described above, the formwork disassembling apparatus X according to the present embodiment includes each clamping mechanism (horizontal beam clamping mechanism A, first outer vertical beam clamping mechanism B, second outer vertical beam clamping mechanism C, intermediate vertical beam clamping mechanism D). ), The panel plate P is pushed up in the direction of being pulled away from the frame material W by the push-up mechanism E in a state where the crosspieces of the frame material W (the horizontal beam W1, the outer vertical beam W2, the intermediate vertical beam W3) are sandwiched. For example, as compared with an embodiment in which the frame member W and the panel plate P are disassembled by punching out the peripheral portion of each nail N, the panel plate P By pushing up itself in the direction of separating from the frame member W, the fixed state of the frame member W and the panel plate P by the fixture N (nail) can be released, and the working efficiency is remarkably improved.
しかも、本実施形態では、この型枠分解装置Ｘに型枠Ｋをセットする際、及び分解作業をする際において型枠分解装置Ｘに対する型枠Ｋの相対位置を決める位置決め手段として機能する第２外縦桟挟持機構Ｃ以外の挟持機構、つまり横桟挟持機構Ａ、第１外縦桟挟持機構Ｂ、中間縦桟挟持機構Ｄにおいて、対向配置した挟持部材同士（第１挟持部材Ａ１と第２挟持部材Ａ２との組、第１挟持部材Ｃ１と第２挟持部材Ｃ２との組、第１挟持部材Ｄ１と第２挟持部材Ｄ２との組）を相互に接近する方向及び離間する方向に移動可能に構成しているため、桟の厚み寸法や、枠材Ｗの組付精度に誤差がある場合であっても、各挟持部材の移動距離や挟持部材同士の離間寸法を適宜変更することにより、各桟を厚み方向の両側面から均等ないしほぼ均等に押圧した状態で的確且つ強固に挟持することができる。したがって、各桟をへし折る方向に無理な押圧力が作用することを回避することができ、分解作業中に桟が割れて破損する事態を防止することができる。 Moreover, in the present embodiment, the second functioning as a positioning means for determining the relative position of the mold K with respect to the mold disassembling apparatus X when setting the mold K in the mold disassembling apparatus X and when performing the disassembling work. In a clamping mechanism other than the outer vertical beam clamping mechanism C, that is, in the horizontal beam clamping mechanism A, the first outer vertical beam clamping mechanism B, and the intermediate vertical beam clamping mechanism D, the clamping members arranged in opposition to each other (the first clamping member A1 and the second clamping member A2). The pair of the clamping member A2, the group of the first clamping member C1 and the second clamping member C2, the group of the first clamping member D1 and the second clamping member D2) can be moved in a direction toward and away from each other. Therefore, even if there is an error in the thickness dimension of the crosspiece and the assembly accuracy of the frame material W, by appropriately changing the moving distance of each clamping member and the separation dimension between the clamping members, Equally or almost evenly from each side in the thickness direction It can be accurately and firmly clamped pressed state. Therefore, it is possible to avoid an excessive pressing force acting in the direction in which each beam is folded, and it is possible to prevent a situation where the beam breaks and breaks during the disassembling work.
さらに、１つの挟持機構（具体的には第２外縦桟挟持機構Ｃ）に、型枠分解装置Ｘに型枠Ｋをセットする際、及び分解作業をする際において型枠分解装置Ｘに対する型枠Ｋの相対位置を決める位置決め手段としての機能を担わせているため、別途専用の位置決め手段（ストッパ等の位置決め部材や、大掛かりな位置決め機構）を設ける態様と比較して、構造の簡素化及びコストの削減を図ることができる。 Further, when setting the mold K to the mold disassembling apparatus X in one clamping mechanism (specifically, the second outer vertical beam clamping mechanism C) and when performing the disassembling work, the mold for the mold disassembling apparatus X is used. Since it has a function as a positioning means for determining the relative position of the frame K, the structure can be simplified and compared with a mode in which a dedicated positioning means (a positioning member such as a stopper or a large positioning mechanism) is separately provided. Cost can be reduced.
また、本実施形態に係る型枠分解装置Ｘは、挟持部材（第１挟持部材Ａ１、第２挟持部材Ａ２、第１挟持部材Ｂ１、第１挟持部材Ｃ１、第２挟持部材Ｃ２、第１挟持部材Ｄ１、第２挟持部材Ｄ２）を接離動作させる駆動手段としてエアシリンダ（エアシリンダＡ３、エアシリンダＢ３、エアシリンダＣ３、エアシリンダＤ３）を適用しているため、各挟持部材の安定した直線的な往復動作を構造の複雑化を招来することなく実現できる。また、エアシリンダによって駆動手段を構成することにより、メンテナンス性やコスト面においても有利なものとなる。 Further, the formwork disassembling apparatus X according to the present embodiment includes a clamping member (a first clamping member A1, a second clamping member A2, a first clamping member B1, a first clamping member C1, a second clamping member C2, and a first clamping member). Since air cylinders (air cylinder A3, air cylinder B3, air cylinder C3, air cylinder D3) are applied as driving means for moving the member D1 and the second clamping member D2) to and from each other, a stable straight line of each clamping member Reciprocal movement can be realized without incurring structural complexity. In addition, configuring the driving means with an air cylinder is advantageous in terms of maintainability and cost.
さらに、各挟持機構（横桟挟持機構Ａ、第１外縦桟挟持機構Ｂ、第２外縦桟挟持機構Ｃ、中間縦桟挟持機構Ｄ）には、挟み込み状態（Ｐ）において桟に引っ掛かってスパイク機能を発揮する滑り止め手段Ａ５（滑り止め用鋲Ａ５、滑り止め用鋲Ｂ５、滑り止め用鋲Ｃ５、滑り止め用鋲Ｄ５）を設けているため、挟み込み状態（Ｐ）において押し上げ機構Ｅによってパネル板Ｐを上方へ押し上げる際に、パネル板Ｐの上方への移動に伴って桟が挟持部材間から抜ける方向へ滑ることを防止することができ、良好な挟持状態を維持し、パネル板Ｐと枠材Ｗとを確実に分解することができる。 Further, each clamping mechanism (horizontal beam clamping mechanism A, first outer vertical beam clamping mechanism B, second outer vertical beam clamping mechanism C, intermediate vertical beam clamping mechanism D) is caught by the beam in the clamping state (P). Anti-slip means A5 (anti-slip kit A5, anti-slip kit B5, anti-slip kit C5, non-slip kit D5) that exhibits a spike function is provided, so that in the pinched state (P), the push-up mechanism E When the panel plate P is pushed upward, it is possible to prevent the crosspieces from slipping in the direction of coming off between the clamping members as the panel plate P moves upward, maintaining a good clamping state. And the frame material W can be reliably disassembled.
また、本実施形態に係る型枠分解装置Ｘでは、パネル板Ｐの下向き面に接触可能な押し上げプレートＥ１と、押し上げプレートＥ１を上下動させる上下動駆動手段Ｅ２とを用いて押し上げ機構Ｅを構成し、上下動駆動手段Ｅ２として油圧シリンダＥ２を適用しているため、油圧シリンダＥ２の加圧調整によりシリンダロッドＥ２２の細かい加減速度を調整することができ、押し上げプレートＥ１の上下方向への移動速度を微調整することが可能である。したがって、押し上げプレートＥ１がパネル板Ｐに接触しない範囲内における押し上げプレートＥ１の移動速度を相対的に早く設定する一方で、押し上げプレートＥ１がパネル板Ｐに接触して上方へ移動する範囲内における押し上げプレートＥ１の移動速度を相対的に遅く設定することにより、パネル板Ｐに対してゆっくりと押し上げる力を作用させることができ、固定具Ｎによる固定状態が解除されたパネル板Ｐが上方へ跳ね上がる不具合を抑制することが可能であり、安全性に優れている。 Further, in the formwork disassembling apparatus X according to the present embodiment, the push-up mechanism E is configured by using the push-up plate E1 that can contact the downward surface of the panel plate P and the vertical movement drive means E2 that moves the push-up plate E1 up and down. Since the hydraulic cylinder E2 is applied as the vertical movement drive means E2, the fine acceleration / deceleration speed of the cylinder rod E22 can be adjusted by adjusting the pressure of the hydraulic cylinder E2, and the moving speed of the push-up plate E1 in the vertical direction Can be finely adjusted. Accordingly, the moving speed of the push-up plate E1 within a range where the push-up plate E1 does not contact the panel plate P is set relatively fast, while the push-up plate E1 pushes up within a range where the push-up plate E1 moves upward while contacting the panel plate P. By setting the moving speed of the plate E1 to be relatively slow, a force for slowly pushing up the panel plate P can be applied, and the panel plate P released from the fixed state by the fixture N jumps upward. Can be suppressed, and is excellent in safety.
なお、本発明は上述した実施形態に限定されるものではない。 In addition, this invention is not limited to embodiment mentioned above.
例えば、上述した実施形態では、挟持機構として、第１挟持部材と第２挟持部材との組を２組有する態様を例示したが、第１挟持部材と第２挟持部材との組を３組以上有する挟持機構、或いは、第１挟持部材と第２挟持部材との組を１組のみ有する挟持機構を採用してもよい。 For example, in the above-described embodiment, the aspect of having two sets of the first clamping member and the second clamping member as the clamping mechanism is illustrated, but three or more sets of the first clamping member and the second clamping member are used. You may employ | adopt the clamping mechanism which has only one set of the clamping mechanism which has, or the group of a 1st clamping member and a 2nd clamping member.
また、全ての挟持機構における第１挟持部材と第２挟持部材とを相互に接離方向に移動可能に構成してもよい。この場合、本装置（型枠分解装置）に型枠をセットする際、及び分解作業をする際において本装置（型枠分解装置）に対する型枠の相対位置を決める位置決め手段を、挟持機構以外の部材を用いて構成すればよい。このようにすれば、上述した実施形態における第２外縦桟挟持機構を第１外縦桟挟持機構と同一ないしほぼ同一の構造にすることができる。 Moreover, you may comprise so that the 1st clamping member and the 2nd clamping member in all the clamping mechanisms can be moved to the contact / separation direction mutually. In this case, positioning means for determining the relative position of the mold relative to the present apparatus (formwork disassembling apparatus) when setting the formwork in the present apparatus (formwork disassembling apparatus) and when performing the disassembling work, other than the clamping mechanism What is necessary is just to comprise using a member. If it does in this way, the 2nd outer vertical beam clamping mechanism in the embodiment mentioned above can be made into the same or almost the same structure as the 1st outer vertical beam clamping mechanism.
また、複数の挟持機構のうち一つの挟持機構に位置決め手段としての機能を担わせる場合、どの挟持機構に位置決め手段としての機能を担わせるかは適宜選択・変更可能である。特に、分解作業中に桟と接触ないし近接して型枠の移動範囲を正常な分解処理を行うことが可能な所定処理スペース内に規制することが可能な挟持機構に位置決め手段としての機能を担わせることが好適である。上述した実施形態では、横桟挟持機構が、横桟を挟持可能な高さ位置と、横桟を挟持不能な高さ位置との間で上下動可能なものであり、この横桟挟持機構を、横桟を挟持不能な高さ位置に設定した場合には桟と接触ないし近接せず、型枠の移動範囲を所定処理スペース内に規制することができないため、第１外縦桟挟持機構、第２外縦桟挟持機構、中間縦桟挟持機構の何れかに位置決め手段としての機能を担わせることが好ましい。 In addition, when one clamping mechanism among the plurality of clamping mechanisms has a function as a positioning unit, which clamping mechanism has a function as a positioning unit can be appropriately selected and changed. In particular, the holding mechanism that can regulate the moving range of the formwork within a predetermined processing space where normal disassembling processing can be performed in contact with or close to the crosspiece during disassembling work serves as a positioning means. Is preferable. In the embodiment described above, the horizontal beam clamping mechanism is capable of moving up and down between a height position at which the horizontal beam can be clamped and a height position at which the horizontal beam cannot be clamped. When the horizontal beam is set to a height position where it cannot be clamped, the first outer vertical beam clamping mechanism is not in contact with or close to the beam and the movement range of the formwork cannot be restricted within a predetermined processing space. It is preferable that either the second outer vertical beam holding mechanism or the intermediate vertical beam holding mechanism has a function as positioning means.
また、上述した実施形態では、各挟持機構において挟持部材をスライド移動させる駆動手段（駆動源）としてエアシリンダを適用したが、エアシリンダ以外のもの、例えばガスシリンダ、油圧シリンダ、電動シリンダ、電気アクチュエータ、或いはモータを挟持機構の駆動手段として用いることもできる。さらに、部品点数は多くなるものの、各挟持機構における各挟持部材をそれぞれ単独の駆動手段によって駆動させるようにしてもよい。この場合、各駆動手段は同種のもの、または異なる種類のもの、何れであっても構わない。 In the above-described embodiments, the air cylinder is applied as a driving means (drive source) for slidingly moving the clamping member in each clamping mechanism. However, other than the air cylinder, for example, a gas cylinder, a hydraulic cylinder, an electric cylinder, and an electric actuator Alternatively, a motor can be used as a driving unit of the clamping mechanism. Furthermore, although the number of parts increases, each clamping member in each clamping mechanism may be driven by a single driving means. In this case, each drive means may be the same type or a different type.
また、上述した実施形態では、押し上げ機構において押し上げプレートを上下動させる上下動駆動手段（駆動源）として油圧シリンダを適用したが、油圧シリンダ以外のもの、例えばガスシリンダ、エアシリンダ、電動シリンダ、電気アクチュエータ、或いはモータを挟持機構の駆動手段として用いることもできる。 In the above-described embodiment, the hydraulic cylinder is applied as the vertical movement drive means (drive source) for moving the push-up plate up and down in the push-up mechanism. However, other than the hydraulic cylinder, such as a gas cylinder, an air cylinder, an electric cylinder, An actuator or a motor can also be used as a driving means for the clamping mechanism.
なお、これら駆動手段（上下動駆動手段を含む）として各種シリンダを適用する場合、シリンダロッドを単純に突没動作させる態様の他、シリンダロッドの全長を伸縮させることによって挟持部材または押し上げプレートを所定方向に往復動させるシリンダであっても勿論構わない。 In addition, when various cylinders are applied as these driving means (including vertical movement driving means), in addition to a mode in which the cylinder rod is simply projected and retracted, the clamping member or the push-up plate is fixed by extending and contracting the entire length of the cylinder rod. Of course, the cylinder may be reciprocated in the direction.
また、上述した実施形態では、各挟持機構において対向配置された挟持部材のうち何れか一方の挟持部材にのみ滑り止め手段を設けた態様を例示したが、両方の挟持部材にそれぞれ滑り止め手段を設けてもよい。なお、本発明者らが、両方の挟持部材にそれぞれ滑り止め手段を設けた挟持機構を有する型枠分解装置によって型枠の分解作業を行ったところ、桟を挟持部材間に挟み込んだ状態から開放状態へ切り替える動作をスムーズに行うことができず、また、桟を開放状態にある挟持部材間を通過させながら型枠全体を搬送方向へ搬送する際に、桟が滑り止め手段に引っ掛かりやすく、搬送処理をスムーズに行うことが困難であった。しかしながら、これらの不具合が、両方の挟持部材にそれぞれ滑り止め手段を設ける技術的思想を本発明の範疇から除外するものではない。 Further, in the above-described embodiment, an example in which the anti-slip means is provided only in one of the holding members opposed to each other in each holding mechanism is illustrated, but the anti-slip means is provided in both of the holding members. It may be provided. In addition, when the present inventors disassembled the formwork by the formwork disassembling apparatus having a holding mechanism in which both the holding members are provided with anti-slip means, respectively, the state where the crosspiece was released between the holding members was released. The operation of switching to the state cannot be performed smoothly, and when the entire frame is conveyed in the conveyance direction while passing between the holding members in the open state, the frame is easily caught by the anti-slip means. It was difficult to perform processing smoothly. However, these problems do not exclude from the scope of the present invention the technical idea of providing anti-slip means for both clamping members.
また、上述した実施形態では、横桟挟持機構を、外縦桟挟持機構（第１外縦桟挟持機構、第２外縦桟挟持機構、中間縦桟挟持機構）よりも型枠の搬送方向下流側、及び搬送方向上流側にそれぞれ設けた態様を例示したが、横桟挟持機構を外縦桟挟持機構よりも型枠の搬送方向下流側にのみ設けた態様であってもよい。この場合、型枠のうち搬送方向上流側の領域を分解する際には、型枠の先頭と後尾とが入れ替わるように型枠を反転させて、分解作業当初は搬送方向上流側にあった横桟を搬送方向下流側に位置付け、この横桟を外縦桟挟持機構よりも型枠の搬送方向下流側に設けた横桟挟持機構によって挟持するようにすればよい。このような態様であれば、型枠を反転させるという工程が増えるものの、横桟挟持機構が１つでよいため、構造の簡素化及び各挟持機構を集約する領域のコンパクト化を図ることができる。 Further, in the above-described embodiment, the horizontal beam clamping mechanism is disposed downstream of the outer vertical beam clamping mechanism (the first outer vertical beam clamping mechanism, the second outer vertical beam clamping mechanism, and the intermediate vertical beam clamping mechanism) in the conveyance direction of the mold. Although the aspect provided respectively in the side and the conveyance direction upstream was illustrated, the aspect provided only in the conveyance direction downstream of the form frame rather than the outer vertical beam clamping mechanism may be sufficient. In this case, when disassembling the upstream area of the mold in the conveyance direction, the mold is inverted so that the top and the tail of the mold are interchanged, and the side that was upstream in the conveyance direction at the beginning of the disassembly work The crosspiece may be positioned on the downstream side in the conveyance direction, and the horizontal crosspiece may be clamped by a horizontal crosspiece holding mechanism provided on the downstream side in the conveyance direction of the mold rather than the outer vertical crosspiece holding mechanism. With such an embodiment, although the process of inverting the formwork is increased, since only one horizontal crossing mechanism is required, the structure can be simplified and the area for consolidating the respective holding mechanisms can be reduced. .
また、型枠は、通常、スクリュー釘等の強固な固定状態を維持し得る固定具によって型枠とパネル板とを固定しているため、上述の実施形態で示すように、型枠を長手方向に複数の領域に分けて領域毎に分解処理を行うことによって、挟持機構及び押し上げ機構に過度の挟持力、押し上げ力を要求せずとも好適に分解処理を行うことができる。 In addition, since the mold is usually fixed to the panel and the panel plate by a fixture that can maintain a strong fixed state, such as a screw nail, the mold is arranged in the longitudinal direction as shown in the above embodiment. By performing the disassembling process for each of the areas divided into a plurality of areas, the disassembling process can be suitably performed without requiring excessive holding force and pushing force for the holding mechanism and the pushing-up mechanism.
また、押し上げ機構における押し上げプレートは各挟持機構と干渉しないスペース内において最大限ないしほぼ最大限の平面寸法を有するものとし、パネル板との接触面積を大きく確保することが好ましく、その平面形状は矩形以外の形状であってもよい。 The push-up plate in the push-up mechanism should have a maximum or almost maximum plane dimension in a space that does not interfere with each clamping mechanism, and it is preferable to ensure a large contact area with the panel plate, and the plane shape is rectangular. Other shapes may be used.
その他、各部の具体的構成についても上記実施形態に限られるものではなく、本発明の趣旨を逸脱しない範囲で種々変形が可能である。 In addition, the specific configuration of each part is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
