Description

本発明は、被処理板材を加熱加圧する横型多段プレス装置の板材位置決め構造に関する。   The present invention relates to a plate material positioning structure of a horizontal multi-stage press apparatus that heats and presses a plate to be processed.

合板、化粧板、繊維板、パーティクルボード、ベニヤ単板等の板材(被処理板材)を加熱加圧して所定の板厚に成形する多段プレス装置(ホットプレス)において、起立状態に保持された複数の板材を複数配置された熱板の間に搬入して加熱加圧する横型方式が知られている。この横型方式(横型ホットプレス)は、水平方向に保持された板材と熱板とを上下方向に交互に積み重ねて加熱加圧する縦型方式(縦型ホットプレス)に比して、板材や熱板自身の重量の影響による成形ムラ(板厚の不揃い)が発生しにくい利点を有する。   In a multi-stage press device (hot press) that heats and presses a plate material (processed plate material) such as plywood, decorative board, fiber board, particle board, veneer veneer, etc., to a predetermined plate thickness, a plurality of pieces held in an upright state A horizontal type is known in which a plurality of plate materials are carried between heated plates arranged and heated and pressed. This horizontal method (horizontal hot press) is a plate material and hot plate compared to the vertical method (vertical hot press) in which plate materials and hot plates held in the horizontal direction are alternately stacked in the vertical direction and heated and pressed. It has the advantage that molding unevenness (uneven thickness) due to its own weight is less likely to occur.

そして、本願出願人はこのような横型ホットプレスにおいて、複数の板材を熱板での押圧位置(シリンダのラム位置を基準とする)に搬入するときに所定の停止位置で停止させるためのストッパ(停止部材)を設けることを提案した(特許文献1参照)   Then, the applicant of the present application in such a horizontal hot press, a stopper for stopping at a predetermined stop position when carrying a plurality of plate materials into a pressing position on the hot plate (based on the ram position of the cylinder) ( Proposed to provide a stop member (see Patent Document 1)

特開昭60−118526号公報JP 60-118526 A

特許文献1によれば、ストッパを熱板での押圧位置に合わせておくだけで、搬入時に複数の板材を所定の押圧位置に揃えて停止させることができるようになり、加熱加圧後の処理済板材に板厚の不揃いを生じにくい。しかし、加熱加圧前の被処理板材は、例えば含水率をとってみても、板材毎に、あるいは1枚の板材でもその部位毎に異なるため、撓み(反り)、捩れ(ひねり)等が一様ではない。このような板材を搬入径路に跨るローラコンベヤ等の搬送体で一斉搬入した場合、所定時間を経過してもストッパに達しないで途中で滞留しやすくなる。このように被処理板材に搬入不足状態(停止位置不揃い)が発生すると、装置全体を停止して人力によって滞留した板材を除去するか所定の停止位置まで移動するかしなければならず、プレス処理の能率を低下させたり、処理済板材に板厚の不揃い等を生じたりするおそれがある。   According to Patent Literature 1, it is possible to stop a plurality of plate materials aligned at a predetermined pressing position at the time of carry-in simply by aligning the stopper with the pressing position on the hot plate. Difficult to produce uneven thickness on finished plate material. However, the plate material to be treated before heating and pressurization is different in each plate material or even in a single plate material even if the moisture content is taken, for example, bending (warping), twisting (twisting), etc. Not like that. When such plate materials are carried in all at once by a conveying body such as a roller conveyor straddling the carry-in path, the plate material does not reach the stopper even after a predetermined time and is likely to stay on the way. Thus, if the board to be processed is not loaded properly (stop position unevenness), the entire apparatus must be stopped to remove the remaining board by human power or move to a predetermined stop position. There is a risk that the efficiency of the sheet will be reduced, or the processed plate material may have uneven thickness.

本発明の課題は、被処理板材の搬入不足状態を是正して加熱加圧処理を能率よく実行でき、処理済板材での板厚の不揃い等の不良品発生を防止できる横型多段プレス装置の板材位置決め構造を提供することにある。   The problem of the present invention is that the plate material of the horizontal multi-stage press apparatus that can correct the insufficient loading state of the plate material to be processed and efficiently execute the heating and pressurizing process, and can prevent the occurrence of defective products such as uneven thickness of the processed plate material. It is to provide a positioning structure.

課題を解決するための手段及び発明の効果Means for Solving the Problems and Effects of the Invention

上記課題を解決するために、本発明の横型多段プレス装置の板材位置決め構造は、
起立状態に保持された複数の被処理板材をその被加圧面に沿って形成される個々の搬入径路に跨って配置された搬送体により、複数配置された熱板の間にそれぞれ搬入し、各被処理板材の厚さ方向を押圧方向としてそれらの被処理板材を前記複数の熱板により一斉に加熱加圧する横型多段プレス装置の板材位置決め構造であって、
前記各被処理板材の搬入径路の搬送方向前方側にそれぞれ配置され、その被処理板材が所定の停止位置まで搬入されたことを前記搬入径路毎に検知する複数の板材検出手段と、
その板材検出手段によりいずれかの被処理板材において前記停止位置まで搬入されずに滞る搬入不足状態を生じていることが検知されたとき、前記熱板による加熱加圧の実行前に作動して、搬入不足状態の被処理板材を対応する搬入径路に沿って前記停止位置までそれぞれ再搬入する補助搬送体とを備えることを特徴とする。
In order to solve the above problems, the plate material positioning structure of the horizontal multi-stage press device of the present invention is:
A plurality of plates to be processed held in an upright state are respectively carried between a plurality of hot plates by a carrier disposed across individual loading paths formed along the surface to be pressed, and each substrate to be processed It is a plate material positioning structure of a horizontal multi-stage press device that heats and presses the processed plate materials all at once with the plurality of hot plates, with the thickness direction of the plate material as the pressing direction,
A plurality of plate material detection means that are arranged on the front side in the conveyance direction of the carry-in path of each of the plate materials to be processed, and that detect the plate material to be carried up to a predetermined stop position for each of the carry-in paths,
When that occurs the carry shortages stagnating without being carried to the stop position in any of the treated plate by its sheet detecting means is detected, it operates before running hot pressing by the hot plate, And an auxiliary conveyance body for re-introducing the to-be-processed plate material in a state of insufficient carry-in along the corresponding carry-in path to the stop position.

このように、被処理板材の搬入径路毎に板材検出手段を配置し、その板材検出手段により搬入不足状態の発生を個別に検知したときに補助搬送体を作動させて被処理板材を所定の停止位置まで再搬入する。したがって、複数の被処理板材を所定の停止位置(押圧位置)に揃え、各被処理板材を挟む複数の熱板により一斉に加熱加圧(プレス成形)することができる。これにより、被処理板材の搬入不足状態が是正され、加熱加圧処理が能率よく実行できる。また、加熱加圧後の処理済板材に板厚の不揃い等が発生しにくくなり、製品歩留りを向上(不良品の発生を減少)させることができる。   In this way, a plate material detection unit is arranged for each carry-in path of the plate material to be processed, and when the occurrence of an insufficient loading state is individually detected by the plate material detection unit, the auxiliary conveyance body is operated to stop the plate material to be processed for a predetermined stop. Reload to position. Therefore, a plurality of plate materials to be processed can be aligned at a predetermined stop position (pressing position) and heated and pressed (press-molded) all at once by a plurality of hot plates that sandwich the plate materials to be processed. As a result, the insufficient loading state of the plate material to be processed is corrected, and the heating and pressing process can be executed efficiently. In addition, unevenness of the plate thickness is less likely to occur in the processed plate after heating and pressing, and the product yield can be improved (the occurrence of defective products can be reduced).

このような板材位置決め構造では、
(1)各搬入径路毎に板材検出手段を設け、すべての搬入径路(又は押圧方向に複数分割した搬入径路)に跨って補助搬送体を設ける方式;
(2)各搬入径路毎に板材検出手段と補助搬送体とを設ける方式;
のいずれを採用してもよい。これらの場合には板材検出手段として、静電容量式等の近接スイッチ、反射型の非接触センサ(反射型光電センサ、反射型超音波センサ等)や接触センサ(リミットスイッチ、マイクロスイッチ等)が望ましい。また、補助搬送体は、板状、柵状、枠状、棒状、管状等の断面形状や、すべての搬入径路に跨って単一の形態、搬入径路を押圧方向に複数分割された形態、搬入径路毎に設けた形態等を含む。なお、(1)の場合に、複数の搬入径路に跨る長さを有する補助搬送体を押圧方向に移動可能とすれば、単一の補助搬送体で構成することもできる。
In such a plate material positioning structure,
(1) A system in which plate material detection means is provided for each carry-in path, and an auxiliary transport body is provided across all the carry-in paths (or multiple carry-in paths divided in the pressing direction);
(2) A method of providing a plate material detecting means and an auxiliary transport body for each carry-in path;
Any of these may be adopted. In these cases, as a plate material detecting means, a proximity switch such as a capacitance type, a reflection type non-contact sensor (a reflection type photoelectric sensor, a reflection type ultrasonic sensor, etc.) or a contact sensor (a limit switch, a micro switch, etc.) desirable. In addition, the auxiliary transport body has a cross-sectional shape such as a plate shape, a fence shape, a frame shape, a rod shape, a tubular shape, a single form across all the carry-in paths, a form in which the carry-in path is divided into a plurality of directions in the pressing direction, The form provided for each path is included. In addition, in the case of (1), if the auxiliary transport body having a length extending over a plurality of carry-in paths can be moved in the pressing direction, it can be constituted by a single auxiliary transport body.

板材位置決め構造の補助搬送体は、搬入径路内に突入して搬入不足状態の被処理板材の搬送方向後端を押すことによりその被処理板材を停止位置まで再搬入する作動状態と、熱板よりも搬送方向後方(上方)側の搬入径路外に退避して次工程の被処理板材の通過を許容する非作動状態とに切換(変位)可能であり、
補助搬送体は、搬送体による被処理板材の搬入の際に非作動状態を保持し板材検出手段が搬入不足状態の被処理板材を検知したときに作動状態に移行(変位)し、次工程の被処理板材の搬入時までに非作動状態に復帰(変位)することが望ましい。
The auxiliary conveyance body of the plate material positioning structure enters the carry-in path and operates by re-loading the processed plate material to the stop position by pressing the rear end in the conveyance direction of the processed plate material that is insufficiently loaded. Can be switched (displaced) to a non-operating state in which the plate material to be processed in the next process is allowed to retreat outside the carry-in path on the rear (upper) side in the transport direction,
The auxiliary transport body is kept in an inactive state when the processed plate material is carried in by the transport body, and shifts to an operating state (displacement) when the plate material detecting means detects the processed plate material that is insufficiently loaded. It is desirable to return (displace) to a non-operating state by the time of carrying in a to-be-processed board | plate material.

このように、補助搬送体は、被処理板材を再搬入する作動状態と搬入径路外に退避する非作動状態とに切り換えられる(変位する)。したがって、搬送体により被処理板材を熱板間(搬入径路)に供給する際には、搬入の妨げにならないように補助搬送体を搬入径路外に退避させて非作動状態に切り換えておけばよい。一方、ひとたび被処理板材に搬入不足が発生した時には補助搬送体が作動状態となって、搬入不足を生じた被処理板材を所定の停止位置まで搬入し直すことができるので、被処理板材に対する加熱加圧処理を停滞させることなく高能率で実行できる。   In this way, the auxiliary transport body is switched (displaced) between an operating state in which the plate material to be processed is reintroduced and a non-operating state in which it is retracted out of the carry-in path. Therefore, when supplying the plate material to be processed between the heat plates (carry-in path) by the transport body, the auxiliary transport body only needs to be retracted outside the carry-in path and switched to the non-operating state so as not to hinder the carry-in. . On the other hand, once there is a shortage of loading in the plate to be processed, the auxiliary transporter is in an operating state, and the plate to be processed in which the shortage of loading has occurred can be reloaded to a predetermined stop position. The pressurization process can be executed with high efficiency without stagnation.

このような補助搬送体が、搬入不足状態の被処理板材を対応する搬入径路の停止位置までそれぞれ再搬入できるように、搬入径路毎に配置されている場合には、板材検出手段が搬入不足状態の被処理板材の存在を検知すると、直ちに補助搬送体を作動してすべての搬入不足状態の被処理板材を同時に再搬入できる。したがって、効率的に搬入不足状態の被処理板材の再搬入を完了して、次の工程(加熱加圧処理工程)に早く移行でき、サイクルタイムを短縮することができる。また、補助搬送体の(駆動源の)駆動力を比較的小さく抑えることができる。すなわち、板材検出手段で搬入不足状態が検知された数の補助搬送体のみを作動させればよいので、すべての搬入径路に跨る単一の補助搬送体を作動させて搬入不足状態の被処理板材を再搬入する場合に比べて動力のロスを抑制できる。   When such an auxiliary conveyance body is arranged for each carry-in path so that the board material to be processed in the carry-in insufficient state can be re-introduced to the stop position of the corresponding carry-in path, the plate material detection means is in a short carry-in state. When the presence of the plate material to be processed is detected, the auxiliary conveyance body is immediately actuated, and all the plate materials to be processed which are in short of loading can be simultaneously loaded again. Accordingly, it is possible to efficiently complete the re-introduction of the plate material to be processed which is in a shortage of the in-carried state, and to quickly move to the next process (heat pressurizing process), thereby shortening the cycle time. Further, the driving force (of the driving source) of the auxiliary transport body can be kept relatively small. In other words, since only the number of auxiliary transport bodies for which the shortage of loading state is detected by the plate material detecting means need be operated, the single auxiliary transport body that straddles all the loading paths is operated and the processed board material in the shortage of loading state The loss of power can be suppressed compared to the case of re-loading.

なお、搬入径路毎に配置された補助搬送体を個別に駆動するには、例えば、補助搬送体を駆動する個々の油圧シリンダ毎に駆動信号を入力したり、電動モータと各補助搬送体との間に介装される個々のクラッチ毎に駆動信号を入力したりすればよい。   In order to individually drive the auxiliary transport body arranged for each carry-in path, for example, a drive signal is input to each hydraulic cylinder that drives the auxiliary transport body, or an electric motor and each auxiliary transport body are connected. What is necessary is just to input a drive signal for each clutch interposed in between.

そして、停止位置には、搬入径路内に突入して被処理板材の前端を受け止める受止状態と、搬入径路外に退避して熱板による加熱加圧の実行が終了した処理済板材の通過を許容する退避状態とに切換(変位)可能な停止部材が配置され、
その停止部材は、搬送体による被処理板材の搬入の際に受止状態を保持し、補助搬送体の作動時にはその受止状態を維持し、搬送体による処理済板材の搬出時までに退避状態に移行(変位)し、次工程の被処理板材の搬入時までに受止状態に復帰(変位)することが望ましい。
And, in the stop position, there is a receiving state that enters the carry-in path and receives the front end of the processed board material, and the passage of the processed board material that has been retreated to the outside of the carry-in path and has finished performing the heating and pressurization by the hot plate. A stop member that can be switched (displaced) to an allowable retracted state is disposed,
The stopping member holds the receiving state when the processed plate material is carried in by the conveying body, maintains the receiving state when the auxiliary conveying member is operated, and is retracted until the processed plate material is carried out by the conveying body. It is desirable to shift to (displace) and return (displace) to a receiving state by the time of carrying in the board material to be processed in the next process.

このように、停止部材は、被処理板材の搬入の際の受止状態と搬入径路外に退避する退避状態とに切り換えられる(変位する)。したがって、搬送体により被処理板材を熱板間(搬入径路)に供給したり、補助搬送体により再搬入する際には、停止部材は搬入径路内に突入して被処理板材の搬送方向前端を受け止めることができるので、各被処理板材を定位置(停止位置)で停止させ、被処理板材に対する加熱加圧処理を停滞させることなく高能率で実行できる。一方、搬送体により処理済板材を搬出する時には、搬出処理に先立って停止部材を搬入径路外に退避させることができるので、搬入径路をそのまま搬出径路として利用することにより搬出処理が滞りなく行なえる。その結果、次工程の搬入処理をスムーズに開始できる。   In this manner, the stop member is switched (displaced) between the receiving state when the processed plate material is carried in and the retreat state where the stopping member is retreated outside the carrying-in path. Therefore, when supplying the plate material to be processed between the heat plates (carrying-in path) by the transport body or re-loading it by the auxiliary transport body, the stop member enters the transport-in path and sets the front end in the transport direction of the plate material to be processed. Since it can be received, each plate material to be processed can be stopped at a fixed position (stop position), and the heating and pressurizing process for the plate material to be processed can be executed with high efficiency without stagnation. On the other hand, when the processed plate material is carried out by the carrier, the stop member can be retracted outside the carry-in path prior to the carry-out process, so that the carry-out process can be performed without delay by using the carry-in path as it is as the carry-out path. . As a result, the next process can be smoothly started.

具体的には、停止部材は受止状態において各被処理板材の停止位置を規定して同時に受け止めできるようにすべての搬入径路に跨って配置されるとともに、複数の板材検出手段は被処理板材の搬入径路毎に位置するように停止部材にそれぞれ固定配置され、
いずれかの板材検出手段が搬入不足状態の被処理板材を検知したときに、補助搬送体はその搬入不足状態の被処理板材を搬送方向後方(上方)側から停止位置まで再搬入することができる。
Specifically, the stop member is arranged across all the carry-in paths so that the stop position of each processed plate material can be defined and received at the same time in the receiving state, and the plurality of plate material detecting means are arranged on the processed plate material. Each stop member is fixedly arranged so as to be positioned for each carry-in path,
When any one of the plate material detecting means detects a processed plate material that is in an insufficiently loaded state, the auxiliary conveyance body can reload the processed plate material in the insufficiently loaded state from the rear (upper) side in the conveying direction to the stop position. .

このように、各板材検出手段を単一の停止部材に固定配置することによって、搬入された各被処理板材の搬送方向前端が停止位置に達しているか否かを、停止部材が受止状態にあるときに被処理板材に接近又は接触して精度よく検出することができる。しかも、停止部材が退避状態にあるときには板材検出手段も搬入径路外に退避するので、処理済板材の通過を阻害せず円滑に搬出することができる。   In this way, by fixing each plate material detection means to a single stop member, whether or not the front end in the conveyance direction of each loaded plate material has reached the stop position, the stop member is in a receiving state. At some point, it can be detected with accuracy by approaching or contacting the plate to be processed. Moreover, when the stop member is in the retracted state, the plate material detecting means is also retracted out of the carry-in path, so that the processed plate material can be smoothly carried out without hindering the passage.

以上のような横型多段プレス装置の板材位置決め構造において、
搬送体により搬入される被処理板材の被加圧面の大きさに応じて、停止部材の配置位置を搬送方向に移動調節する調節手段と、
停止部材の近傍であって搬送方向前方側には、搬送体による処理済板材の搬出の際にその処理済板材の下端面を下側から支持するためにすべての搬入径路に跨る処理済板材支持面を有する処理済板材支持手段とを備え、
その処理済板材支持手段は、停止部材が受止状態であるか退避状態であるかにかかわらず(それとは関係なく)、処理済板材支持面が搬送体により形成される処理済板材の搬送面の延長上に位置するとともに、調節手段による停止部材の配置位置調節状態においてその停止部材とともに搬送方向に移動(変位)することもできる。
In the plate material positioning structure of the horizontal multi-stage press apparatus as described above,
An adjusting means for moving and adjusting the disposition position of the stop member in the transport direction according to the size of the pressed surface of the processed plate material carried in by the transport body;
In the vicinity of the stop member and on the front side in the transport direction, when the processed plate material is carried out by the transport body, the processed plate material is supported across all the carry-in paths in order to support the lower end surface of the processed plate material from below. A treated plate material support means having a surface,
The processed plate material support means is a conveyance surface of the processed plate material on which the processed plate material support surface is formed by the conveyance body regardless of whether the stop member is in a receiving state or in a retracted state It is also possible to move (displace) in the transport direction together with the stop member in a state where the stop member is positioned by the adjusting means.

このように、受止状態と退避状態とに切り換えられる停止部材が、位置変化を伴う(特に、退避状態で搬入径路外に退避する)ことによって被処理板材の搬出に支障を来たすことのないように、停止部材の近傍には、処理済板材を下側から支持する処理済板材支持手段が設けられる。したがって、処理済板材支持手段を備えることにより、停止部材の移動領域において、搬出される処理済板材の保持姿勢(下側からの支持状態)が不安定となって傾く(搬送方向に対して傾斜する)ことを防止している。その際、停止部材が受止状態であるか退避状態であるかにかかわらず(すなわち、停止部材が搬入径路外に退避しているか否かとは関係なく)、処理済板材支持面が搬送面の延長上に位置しすべての搬入径路に跨って配置されているので、処理済板材を常時安定して保持することができる。なお、処理済板材支持手段を例えば円筒状ローラで構成し、単独で駆動回転して処理済板材を下側から支えつつ搬送(搬出)できる。   As described above, the stop member that can be switched between the receiving state and the retracted state is accompanied by a change in position (especially, retracting out of the loading path in the retracted state) so as not to hinder the unloading of the processed plate material. In addition, a processed plate material support means for supporting the processed plate material from below is provided in the vicinity of the stop member. Therefore, by providing the processed plate material support means, the holding posture (supported state from the lower side) of the processed plate material to be carried out is inclined in the movement region of the stop member (inclined with respect to the conveyance direction). To prevent). At that time, regardless of whether the stop member is in the receiving state or in the retracted state (that is, regardless of whether or not the stop member is retracted outside the carry-in path), the processed plate material support surface is Since it is located on the extension and disposed across all the carry-in paths, the processed plate material can be held stably at all times. The processed plate material support means is constituted by, for example, a cylindrical roller, and can be transported (carried out) while being driven and rotated independently to support the processed plate material from below.

A hot plate group is formed by being suspended in parallel. Further, when the press is released, the adjacent hot plates 130 are positioned parallel to the transport direction so as to maintain a predetermined interval so that the processed plate material W1 can be inserted between the hot plates 130 in the hot plate group. In addition, steam, hot oil, etc. are supplied / exhausted in the inside of the hot plate 130, and the temperature is maintained according to the kind of to-be-processed board | plate material W1.

Further, the pressing plates 140F and 140B are connected to the rams 151L and 151R of the hydraulic cylinders 150L and 150R provided on the fixed frames 103F and 103B, and can be reciprocated in the front-rear direction by the rams 151L and 151R. Note that the pressing plates 140F and 140B in FIG. 3 reciprocate in the front-rear direction with respect to the fixed frames 103F and 103B.

熱板群における熱板130相互間、及び両端部の熱板130と押圧盤140F,140Bとは、プレス開放時に所定の前後間隔を保持するために、それぞれ間隔規制具131で連繋されている。間隔規制具131は門型に形成され、熱板130、押圧盤140F,140Bの上方側で隣接するブラケット132相互に架け渡し、その一端をブラケット132に取り付け、他端を自由端とする。プレス開放時に、間隔規制具131の自由端がブラケット132に係止され、熱板130、押圧盤140F,140Bにおける前後の間隔が一定の幅で規制される。   The hot plates 130 in the hot plate group, and the hot plates 130 at both ends and the press plates 140F and 140B are connected to each other by a space restricting tool 131 in order to maintain a predetermined front-rear space when the press is released.

A roller conveyor 160 is disposed, and the upper surface of the plurality of claw-equipped rollers 161 serves as a conveyance surface.

次に、図6は板材位置決め構造の正面図、図7はその要部拡大正面図、図8は要部拡大平面図を示す。図6に示すように、ホットプレス部100(加熱加圧部;プレス構造)には、n枚(例えば100枚)の被処理板材W1に対応して設けられるn個の搬入径路Ka〜Knにおいて、各搬入径路Ka〜Knの前方側(先頭側;右側)に配置されたストッパ170(停止部材;板材位置決め構造)と、このストッパ170に配置されたn個の近接スイッチ10a〜10n(非接触センサ;板材検出手段;板材位置決め構造)と、各搬入径路Ka〜Knの後方側(末尾側;左側)に配置されたn本の作動アーム180a〜180n(補助搬送体;板材位置決め構造)とが備えられている。   Next, FIG. 6 is a front view of the plate material positioning structure, FIG. 7 is an enlarged front view of the main part, and FIG. 8 is an enlarged plan view of the main part. As shown in FIG. 6, in the hot press part 100 (heat pressurizing part; press structure), n carry-in paths Ka to Kn provided corresponding to n (for example, 100) processed plate materials W1. A stopper 170 (stop member; plate material positioning structure) disposed on the front side (leading side; right side) of each carry-in path Ka to Kn, and n proximity switches 10a to 10n (non-contact) disposed on the stopper 170 Sensor; plate material detection means; plate material positioning structure) and n operation arms 180a to 180n (auxiliary transfer body; plate material positioning structure) arranged on the rear side (tail side; left side) of the respective carry-in paths Ka to Kn. Is provided.

ストッパ170はすべての搬入径路Ka〜Knに跨って各被処理板材W1の搬入停止位置に配置され、各々の近接スイッチ10a〜10nは各被処理板材W1が停止位置(ストッパ170位置)まで搬入されたことを個別に検知し、各々の作動アーム180a〜180nは搬入不足状態の各被処理板材W1を対応する搬入径路Ka〜Knに沿って停止位置(ストッパ170位置)まで再搬入する。つまり、ストッパ170が配置された被処理板材W1の搬入停止位置は、熱板130による被処理板材W1の押圧位置(加熱加圧位置)を表わしている。   The stopper 170 is disposed at the loading stop position of each plate material W1 across all the carry-in paths Ka to Kn, and each proximity switch 10a to 10n loads each plate material W1 to the stop position (stopper 170 position). This is detected individually, and each of the operating arms 180a to 180n re-loads the processing target plate material W1 in a state of insufficient loading along the corresponding loading paths Ka to Kn to the stop position (stopper 170 position). That is, the carry-in stop position of the processing target plate material W1 where the stopper 170 is arranged represents the pressing position (heating and pressing position) of the processing target plate material W1 by the hot plate 130.

ストッパ170は、図7に示すように熱板130の下方において、受止状態P1(停止位置)と退避状態P2(退避位置)とに切換(変位)可能である。受止状態P1においてストッパ170は、搬入径路Ka〜Kn内に突入して被処理板材W1の前端(右端)を受け止める。一方、退避状態P2においてストッパ170は、搬入径路Ka〜Kn外に退避して熱板130による加熱加圧の実行が終了した処理済板材W2の通過を許容する。よって、ストッパ170は、ローラコンベヤ160による被処理板材W1の搬入の際に受止状態P1を保持し、作動アーム180a〜180nの作動時(再搬入)には受止状態P1を維持し、ローラコンベヤ160による処理済板材W2の搬出時までに退避状態P2に移行(変位)し、次工程の被処理板材W1の搬入時までに受止状態P1に復帰(変位)する。   As shown in FIG. 7, the stopper 170 can be switched (displaced) between a receiving state P <b> 1 (stop position) and a retracted state P <b> 2 (retracted position) below the heat plate 130. In the receiving state P1, the stopper 170 enters the carry-in paths Ka to Kn and receives the front end (right end) of the processed plate material W1. On the other hand, in the retracted state P2, the stopper 170 allows passage of the processed plate material W2 that has been retracted outside the carry-in paths Ka to Kn and has been subjected to the heating and pressurization by the hot plate 130. Therefore, the stopper 170 holds the receiving state P1 when the processing plate material W1 is carried in by the roller conveyor 160, and maintains the receiving state P1 when the operating arms 180a to 180n are operated (re-loading). By the time when the processed plate material W2 is carried out by the conveyor 160, it shifts (displaces) to the retracted state P2, and returns (displaces) to the receiving state P1 by the time when the processed plate material W1 in the next process is carried in.

つまり、ストッパ170は、常時被処理板材W1の搬入停止位置前端(右端)に配置されている。上昇して受止状態P1のストッパ170は、ローラコンベヤ160の搬送面160aよりも高位に位置して、搬入された被処理板材W1の前端(右端)を受け止める。また、下降して退避状態P2のストッパ170は、ローラコンベヤ160の搬送面160aよりも低位に位置している。そしてストッパ170は、受止状態P1において各被処理板材W1の停止位置を規定して同時に受け止めできるように、すべての搬入径路Ka〜Knに跨って配置されている(図8参照)。   That is, the stopper 170 is always disposed at the front end (right end) of the loading stop position of the processed plate material W1. The stopper 170 in the received state P1 is positioned higher than the transport surface 160a of the roller conveyor 160 and receives the front end (right end) of the loaded plate material W1. Further, the stopper 170 in the lowered and retracted state P <b> 2 is positioned lower than the conveying surface 160 a of the roller conveyor 160. And the stopper 170 is arrange | positioned ranging over all the carrying-in paths Ka-Kn so that the stop position of each to-be-processed board | plate material W1 may be prescribed | regulated and received simultaneously in the receiving state P1 (refer FIG. 8).

ストッパ170の退避状態P2と受止状態P1との切り換えは、ストッパ昇降用シリンダ171(リニア駆動源;図9参照)により行われる。また、ストッパ170は、被処理板材W1の被加圧面の大きさに応じて、ストッパ移動用シリンダ172(リニア駆動源;調節手段;図8参照)により熱板130の下方で停止位置を左右方向(搬送方向)に移動調節可能である。   Switching between the retracted state P2 and the receiving state P1 of the stopper 170 is performed by a stopper lifting cylinder 171 (linear drive source; see FIG. 9). In addition, the stopper 170 is set to a stop position below the hot plate 130 in the horizontal direction by a stopper moving cylinder 172 (linear drive source; adjusting means; see FIG. 8) according to the size of the pressed surface of the plate material W1. The movement can be adjusted in the (conveyance direction).

ストッパ170の支持構造についてさらに説明する。図7及び図8に示すように、ローラコンベヤ160の下方において、前後および左右に各一対(計4本)の支柱123が設置してある。このうち、前後の支柱123間にわたって左右の下横梁102L,102Rを架け渡すとともに、右側の下横梁102Rとストッパ170との間には前後方向に所定間隔をもって複数(例えば2本)のストッパ移動用シリンダ172を架け渡している。   The support structure for the stopper 170 will be further described. As shown in FIGS. 7 and 8, a pair (four in total) of columns 123 are installed on the front and rear and on the left and right below the roller conveyor 160. Among these, the left and right lower horizontal beams 102L and 102R are bridged between the front and rear columns 123, and a plurality of (for example, two) stoppers are moved between the right lower horizontal beam 102R and the stopper 170 at a predetermined interval in the front-rear direction. The cylinder 172 is bridged.

具体的には、図7に示すように、ストッパ170の下方にあってストッパ170を支持する断面矩形筒状の支持枠175(支持体;図9参照)に、左右方向(搬送方向)に配置されるストッパ移動用シリンダ172のロッド172a先端を固定してある。また、図8に示すように、右側の下横梁102Rに固定され搬送方向前方側(右側)に延びる水平梁177とその下横梁102Rとの間には、支持枠175を左右方向に貫通する形態で複数(例えば4本)の移動ガイド176(案内体)が固定されている。これによって、ストッパ移動用シリンダ172は、ロッド172aの伸縮により移動ガイド176に案内されて支持枠175を左右スライド移動する。   Specifically, as shown in FIG. 7, the support frame 175 (support body; see FIG. 9) below the stopper 170 and supporting the stopper 170 is arranged in the left-right direction (conveyance direction). The tip of the rod 172a of the stopper moving cylinder 172 is fixed. Further, as shown in FIG. 8, the horizontal frame 177 is fixed to the right lower horizontal beam 102 </ b> R and extends forward (right side) in the conveyance direction, and the lower horizontal beam 102 </ b> R penetrates the support frame 175 in the left-right direction. A plurality of (for example, four) movement guides 176 (guide bodies) are fixed. Thus, the stopper moving cylinder 172 is guided by the movement guide 176 by the expansion and contraction of the rod 172a and slides the support frame 175 left and right.

図9に示すように、支持枠175には、その支持枠175を上下方向に貫通する形態で配置されたストッパ昇降用シリンダ171の下端が固定され、ストッパ昇降用シリンダ171のロッド171a上端は、直角状(例えばL字状)に形成されたストッパ170の水平部170aに固定されている。また、支持枠175にはストッパ昇降用シリンダ171と平行状に貫通する形態で配置された昇降ガイド178(案内体)の下端が固定され、昇降ガイド178の上端はストッパ170の水平部170aを貫通して垂直部170bと平行状に突出している。これによって、ストッパ昇降用シリンダ171は、ロッド171aの伸縮により昇降ガイド178に案内されてストッパ170を上下スライド移動する。   As shown in FIG. 9, the lower end of the stopper lifting cylinder 171 arranged in a form penetrating the support frame 175 in the vertical direction is fixed to the support frame 175, and the upper end of the rod 171 a of the stopper lifting cylinder 171 is It is fixed to a horizontal portion 170a of a stopper 170 formed in a right angle (for example, L shape). Further, the lower end of a lifting guide 178 (guide body) disposed in a form penetrating in parallel with the stopper lifting cylinder 171 is fixed to the support frame 175, and the upper end of the lifting guide 178 passes through the horizontal portion 170 a of the stopper 170. Thus, it protrudes in parallel with the vertical portion 170b. Accordingly, the stopper elevating cylinder 171 is guided by the elevating guide 178 by the expansion and contraction of the rod 171a to slide the stopper 170 up and down.

図7及び図8に示すように、各近接スイッチ10a〜10nがストッパ170に固定配置されている。これらの近接スイッチ10a〜10nは各被処理板材W1の搬入径路Ka〜Kn毎に位置するように配置されている。つまり近接スイッチ10a〜10nは、前後方向(押圧方向)において各搬入径路Ka〜Kn毎に配置され、停止位置(ストッパ170位置)まで搬入されずに滞る搬入不足状態の被処理板材W1の有無を検知する。   As shown in FIGS. 7 and 8, the proximity switches 10 a to 10 n are fixedly disposed on the stopper 170. These proximity switches 10a to 10n are arranged so as to be positioned for the respective carry-in paths Ka to Kn of the respective plate materials W1 to be processed. That is, the proximity switches 10a to 10n are arranged for each of the carry-in paths Ka to Kn in the front-rear direction (pressing direction), and the presence or absence of the unprocessed plate material W1 that is not loaded to the stop position (stopper 170 position) is detected. Detect.

図7に示すように、各作動アーム180a〜180nが各搬入径路Ka〜Knの後方側における熱板130の上方にそれぞれ配置されている。そして、近接スイッチ10a〜10nがいずれかの搬入径路Ka〜Knで搬入不足状態の被処理板材W1を検知すると、熱板130による加熱加圧の実行前に、作動アーム180a〜180nは、その搬入不足状態の被処理板材W1のみを搬送方向後方側(左側)から押して停止位置まで再搬入するように制御される。   As shown in FIG. 7, the operating arms 180 a to 180 n are arranged above the heat plate 130 on the rear side of the carry-in paths Ka to Kn, respectively. And when proximity switch 10a-10n detects the to-be-processed board | plate material W1 in a carrying-in insufficient state in any carrying-in path Ka-Kn, before execution of the heating pressurization by the hot plate 130, the action | operation arm 180a-180n will carry in the carrying-in. Control is performed such that only the insufficiently processed plate material W1 is pushed from the rear side (left side) in the transport direction and re-loaded to the stop position.

これらの作動アーム180a〜180nは、各々独立して作動状態Q1(作動位置)と非作動状態Q2(非作動位置)とに切換(変位)可能である。作動状態Q1において作動アーム180a〜180nは、搬入径路Ka〜Kn内に突入して搬入不足状態の被処理板材W1の搬送方向後端(左端)を押すことにより、被処理板材W1を停止位置(ストッパ170位置)まで再搬入する。一方、非作動状態Q2において作動アーム180a〜180nは、搬入径路Ka〜Kn外に退避して次工程の被処理板材W1の通過を許容する。よって、ローラコンベヤ160による被処理板材W1の搬入の際に、全作動アーム180a〜180nが非作動状態Q2を保持する。一方、近接スイッチ10a〜10nが搬入不足状態の被処理板材W1を個別に検知したときに、対応する作動アーム180a〜180nのみが作動状態Q1に移行(変位)し、次工程の被処理板材W1の搬入時までに非作動状態Q2に復帰(変位)する。   These operating arms 180a to 180n can be independently switched (displaced) between an operating state Q1 (operating position) and a non-operating state Q2 (non-operating position). In the operation state Q1, the operation arms 180a to 180n enter the carry-in paths Ka to Kn and push the rear end (left end) in the conveyance direction of the plate material W1 which is not loaded enough to stop the plate material W1 to be stopped ( Reload to stopper (170 position). On the other hand, in the non-operating state Q2, the operating arms 180a to 180n retreat out of the carry-in paths Ka to Kn and allow the processed plate material W1 in the next process to pass. Accordingly, when the plate material W1 is carried in by the roller conveyor 160, all the operating arms 180a to 180n hold the non-operating state Q2. On the other hand, when the proximity switches 10a to 10n individually detect the to-be-processed plate material W1 in a state where loading is insufficient, only the corresponding operating arms 180a to 180n shift (displace) to the operating state Q1, and the next-processed plate material W1. Is returned (displaced) to the non-operating state Q2 by the time of loading.

つまり、作動アーム180a〜180nは、搬送方向後方側でプレス閉鎖およびプレス開放における熱板130の移動に支障が生じない位置に配置される。作動アーム180a〜180nは、搬入不足状態の被処理板材W1を個別に停止位置まで再搬入できるように、すべての搬入径路Ka〜Kn毎に配置されている(図8参照)。   In other words, the operating arms 180a to 180n are disposed at positions that do not hinder the movement of the hot plate 130 during the press closing and the press opening on the rear side in the transport direction. The operation arms 180a to 180n are arranged for all the carry-in paths Ka to Kn so that the plate material W1 in the carry-in insufficient state can be individually re-loaded to the stop position (see FIG. 8).

図6に戻り、各々の作動アーム180a〜180nの作動状態Q1(作動位置)と非作動状態Q2(非作動位置)との切換えは、熱板130の上方において上方の横梁101Lに端部が連結された作動アーム用シリンダ181a〜181n(駆動源)により行われる。   Returning to FIG. 6, the switching between the operating state Q <b> 1 (operating position) and the non-operating state Q <b> 2 (non-operating position) of each operating arm 180 a-180 n is connected to the upper cross beam 101 </ b> L above the hot plate 130. The operation arm cylinders 181a to 181n (drive sources) are used.

作動アーム180a〜180nの支持構造について図6〜図8によりさらに説明する。図8において、熱板130の上方で支持軸182がすべての搬入径路Ka〜Knを跨ぐように配設されている。この支持軸182は、上方の横梁101Lからローダ部200側へ延出している一対の支持軸固定梁183、183a間に横架している。   The support structure of the operating arms 180a to 180n will be further described with reference to FIGS. In FIG. 8, the support shaft 182 is disposed above the hot plate 130 so as to straddle all the carry-in paths Ka to Kn. The support shaft 182 extends horizontally between a pair of support shaft fixing beams 183 and 183a extending from the upper horizontal beam 101L to the loader unit 200 side.

図6において、作動アーム180a〜180nは、それぞれが支持軸182に回転自在に装着されている。作動アーム180a〜180nはL形に形成され、被処理板材W1に当接して再搬入するための長辺部184と、作動アーム用シリンダ181a〜181nに連結する短辺部185を備えている。この短辺部185の中間には支持軸182が貫通するとともに、短辺部185の先端に作動アーム用シリンダ181a〜181nのロッド186を連結し、作動アーム用シリンダ181a〜181nの作動により搬入不足状態の被処理板材W1を個別に停止位置まで再搬入できるようにしている。   In FIG. 6, each of the operation arms 180 a to 180 n is rotatably mounted on the support shaft 182. The operating arms 180a to 180n are formed in an L shape, and include a long side portion 184 for coming into contact with the processing target plate material W1 and a short side portion 185 connected to the operating arm cylinders 181a to 181n. The support shaft 182 passes through the middle of the short side portion 185, and the rod 186 of the operating arm cylinders 181a to 181n is connected to the tip of the short side portion 185, and the loading of the operating arm cylinders 181a to 181n is insufficient. The processed plate material W1 in a state can be individually carried back to the stop position.

図8に示すように、ストッパ170には搬出側補助ローラ173(処理済板材支持手段)が付設され、搬出側補助ローラ用モータ174(回転駆動源)によって独自に回転する。搬出側補助ローラ173は、ストッパ170の近傍で搬送方向前方側(右側)に配置され、ローラコンベヤ160による処理済板材W2の搬出の際に処理済板材W2の下端面を下側から支持するために、すべての搬入径路Ka〜Knに跨る処理済板材支持面173a(図7参照)を有する。   As shown in FIG. 8, the stopper 170 is provided with a carry-out side auxiliary roller 173 (processed plate material support means), and is independently rotated by a carry-out side auxiliary roller motor 174 (rotation drive source). The carry-out side auxiliary roller 173 is disposed on the front side (right side) in the transport direction in the vicinity of the stopper 170, and supports the lower end surface of the processed plate material W2 from below when the processed plate material W2 is transferred by the roller conveyor 160. Furthermore, it has the processed board material support surface 173a (refer FIG. 7) ranging over all the carrying-in paths Ka-Kn.

図7に示すように、搬出側補助ローラ173は支持枠175に取り付けられているので、処理済板材支持面173aは、ストッパ170が受止状態P1であるか退避状態P2であるかとは関係なく、常時ローラコンベヤ160の搬送面160aの延長上(同じ高さ)に位置している。そして搬出側補助ローラ173は、ストッパ移動用シリンダ172のロッド172aの伸縮に伴うストッパ170の配置位置調節状態において、ストッパ170とともに左右方向(搬送方向の前方側又は後方側)に移動(変位)する。したがって、搬出側補助ローラ173は、ストッパ移動用シリンダ172によって移動(変位)するが、ストッパ昇降用シリンダ171によって昇降(変位)しない。   As shown in FIG. 7, since the carry-out side auxiliary roller 173 is attached to the support frame 175, the processed plate material support surface 173a has no relation to whether the stopper 170 is in the receiving state P1 or the retracted state P2. It is always located on the extension (same height) of the conveying surface 160a of the roller conveyor 160. The carry-out side auxiliary roller 173 moves (displaces) together with the stopper 170 in the left-right direction (the front side or the rear side in the conveying direction) in a state in which the stopper 170 is disposed in accordance with the expansion and contraction of the rod 172a of the stopper moving cylinder 172. . Accordingly, the carry-out side auxiliary roller 173 moves (displaces) by the stopper moving cylinder 172, but does not move up and down (displaced) by the stopper lifting cylinder 171.

図7及び図8に示すように、熱板130の下方において、搬入側補助ローラ193が配置されている。搬入側補助ローラ193は、搬入側補助ローラ用モータ194(回転駆動源)によって独自に回転する。搬入側補助ローラ193は、搬送方向後方側(左側)に配置され、ローラコンベヤ160への被処理板材W1の搬入の際に被処理板材W1の下端面を下側から支持するために、すべての搬入径路Ka〜Knに跨る被処理板材支持面193a(図7参照)を有する。   As shown in FIGS. 7 and 8, a carry-in side auxiliary roller 193 is disposed below the hot plate 130. The carry-in side auxiliary roller 193 is independently rotated by a carry-in side auxiliary roller motor 194 (rotation drive source). The carry-in side auxiliary roller 193 is arranged on the rear side (left side) in the conveyance direction, and supports all the lower end surfaces of the plate material W1 to be processed from the lower side when the plate material W1 is loaded into the roller conveyor 160. It has the to-be-processed board | plate material support surface 193a (refer FIG. 7) ranging over carrying-in path Ka-Kn.

次に、図11のフローチャートと図12の作動説明図とを用いて、ホットプレス部100における板材の位置決め制御について説明する。図11のフローチャートは、図10のROM23に格納された制御プログラム23aに対応している。   Next, the plate material positioning control in the hot press unit 100 will be described with reference to the flowchart of FIG. 11 and the operation explanatory diagram of FIG. The flowchart of FIG. 11 corresponds to the control program 23a stored in the ROM 23 of FIG.

まず、S1にて設定スイッチ20aにより被処理板材W1の被加圧面の大きさを手操作入力する。その入力内容に基づき、ROM23の設定テーブル23b(図10)を参照して初期設定を行う。具体的には、S2において、被処理板材W1の大きさに応じてストッパ移動用シリンダ172によりストッパ170と搬出側補助ローラ173の配置位置(搬入先頭位置)を移動調節し、作動用アームシリンダ181a〜181nにより作動アーム180a〜180nの停止位置(搬入末尾位置)を移動調節する(図7参照)。次いで、S3にてストッパ昇降用シリンダ171によりストッパ170を受止状態P1に上昇変位し、同時にS4にて作動用アームシリンダ181a〜181nにより作動アーム180a〜180nを非作動状態Q2に変位する(図12(a)参照)。   First, in S1, the size of the pressed surface of the processed plate material W1 is manually input by the setting switch 20a. Based on the input contents, initial setting is performed with reference to the setting table 23b (FIG. 10) of the ROM 23. Specifically, in S2, the arrangement position (carrying head position) of the stopper 170 and the carry-out side auxiliary roller 173 is moved and adjusted by the stopper moving cylinder 172 according to the size of the processed plate material W1, and the operating arm cylinder 181a is adjusted. The stopping position (loading end position) of the operating arms 180a to 180n is moved and adjusted by ˜181n (see FIG. 7). Next, in S3, the stopper 170 is lifted and displaced to the receiving state P1 by the stopper raising / lowering cylinder 171. At the same time, the operating arm cylinders 181a to 181n are displaced to the non-operating state Q2 by the operating arm cylinders 181a to 181n in FIG. 12 (a)).

さらに、S5にてローラコンベヤ用モータ162によりローラコンベヤ160を所定時間駆動回転し、同時に搬入側補助ローラ用モータ194により搬入側補助ローラ193を所定時間駆動回転して、被処理板材W1を搬入径路Ka〜Knに搬入する(図12(a)参照)。S7にていずれかの近接スイッチ10a〜10nが各搬入径路Ka〜Knで搬入不足状態の被処理板材W1’(図12(a)参照)を検知しているかを確認する。いずれかの近接スイッチ10a〜10nが搬入不足状態を検知していれば(S7でYES)、S8にて搬入不足が検知された搬入径路Ka〜Knに対応する作動用アームシリンダ181a〜181nを駆動し、作動アーム180a〜180nを作動状態Q1に変位させて、搬入不足状態の被処理板材W1’のみを搬入径路Ka〜Knに沿って再搬入する(図12(b)参照)。   Further, in S5, the roller conveyor 160 is driven to rotate for a predetermined time by the roller conveyor motor 162, and at the same time, the carry-in side auxiliary roller 193 is driven to rotate for a predetermined time by the carry-in side auxiliary roller motor 194, thereby bringing the processed plate material W1 into the carry-in path. It carries in to Ka-Kn (refer Fig.12 (a)). In S7, it is confirmed whether any of the proximity switches 10a to 10n detects the processed board material W1 '(see FIG. 12A) that is in an insufficiently loaded state in each of the loading paths Ka to Kn. If any one of the proximity switches 10a to 10n detects a carry-in insufficient state (YES in S7), the actuation arm cylinders 181a to 181n corresponding to the carry-in paths Ka to Kn in which the carry-in shortage is detected in S8 are driven. Then, the operating arms 180a to 180n are displaced to the operating state Q1, and only the to-be-processed plate material W1 ′ that is insufficiently loaded is reloaded along the loading paths Ka to Kn (see FIG. 12B).

その後、S10にてすべての近接スイッチ10a〜10nが被処理板材W1の搬入完了を検知しているかを確認する。すべての近接スイッチ10a〜10nが搬入完了を検知していれば(S10でYES)、S11にてホットプレス用シリンダ150L,150Rにより熱板130を閉鎖し、S12にて被処理板材W1を所定時間ホットプレス(加熱加圧)し、S13にて熱板130を開放する。S14にてストッパ昇降用シリンダ171によりストッパ170を退避状態P2に下降変位する(図12(c)参照)。続いて、S15にてローラコンベヤ用モータ162によりローラコンベヤ160を所定時間駆動回転し、同時にS16にて搬出側補助ローラ用モータ174により搬出側補助ローラ173を所定時間駆動回転して、処理済板材W2を搬入径路Ka〜Knから搬出する(図12(c)参照)。その後、S3にリターンして次工程の被処理板材W1の搬入を開始する。   Thereafter, in S10, it is confirmed whether all the proximity switches 10a to 10n have detected the completion of the loading of the processed plate material W1. If all the proximity switches 10a to 10n detect completion of loading (YES in S10), the hot plate 130 is closed by the hot press cylinders 150L and 150R in S11, and the processed plate material W1 is kept in the predetermined time in S12. Hot pressing (heating and pressing) is performed, and the hot plate 130 is opened in S13. In S14, the stopper 170 is moved downwardly to the retracted state P2 by the stopper lifting / lowering cylinder 171 (see FIG. 12C). Subsequently, in S15, the roller conveyor 160 is driven and rotated by the roller conveyor motor 162 for a predetermined time, and at the same time, the unloading side auxiliary roller 173 is driven and rotated by the unloading side auxiliary roller motor 174 in S16. W2 is unloaded from the loading paths Ka to Kn (see FIG. 12C). Then, it returns to S3 and starts carrying in the to-be-processed board | plate material W1 of the next process.

なお、すべての近接スイッチ10a〜10nが搬入不足状態を検知していなければ(S7でNO)、作動アーム180a〜180nによる再搬入を行うことなくS11以降のホットプレスを実行する。また、作動アーム180a〜180nによる再搬入後もいずれかの近接スイッチ10a〜10nが搬入不足状態を検知していれば(S10でNO)、S17にて「搬入不足状態継続中」の警報を発して制御を停止する。   If all the proximity switches 10a to 10n have not detected the carry-in insufficient state (NO in S7), the hot press after S11 is executed without performing re-loading with the operating arms 180a to 180n. In addition, if any of the proximity switches 10a to 10n detects an insufficient loading state even after re-loading by the operating arms 180a to 180n (NO in S10), an alarm “in the state of insufficient loading” is issued in S17. To stop control.

以上のように、被処理板材W1の搬入径路Ka〜Knの搬送方向前方に近接スイッチ10a〜10nを配置し、その近接スイッチ10a〜10nにより搬入不足状態の発生を検知したときに、作動アーム180a〜180nを個別に作動させて被処理板材W1を所定の停止位置(ストッパ170位置)まで再搬入する。このようにして、複数の被処理板材W1を所定の停止位置(押圧位置)に揃えた後、各被処理板材W1を挟む複数の熱板130により一斉に熱プレス成形できる。したがって、被処理板材W1の搬入不足状態が速やかに是正され、熱プレス処理が能率よく実行できる。また、熱プレス後の処理済板材W2に板厚の不揃い等が発生しにくくなり、製品歩留りが向上(不良品の発生が減少)する。しかも、近接スイッチ10a〜10nを用いることによって、個別に搬入不足状態の発生を検知することができる。   As described above, when the proximity switches 10a to 10n are disposed in front of the conveyance paths Ka to Kn of the plate material W1 to be processed and the proximity switches 10a to 10n detect the occurrence of the insufficient loading state, the operating arm 180a. ˜180n are individually operated to re-load the plate material W1 to a predetermined stop position (stopper 170 position). In this way, after the plurality of plate materials W1 are aligned at a predetermined stop position (pressing position), the hot plate molding can be performed simultaneously by the plurality of hot plates 130 sandwiching the plate materials W1 to be processed. Therefore, the insufficient loading state of the plate material W1 to be processed is quickly corrected, and the hot press process can be executed efficiently. Further, unevenness of the plate thickness is less likely to occur in the processed plate material W2 after the hot pressing, and the product yield is improved (the occurrence of defective products is reduced). Moreover, by using the proximity switches 10a to 10n, it is possible to individually detect the occurrence of an insufficient carry-in state.

さらに、ストッパ170には被駆動式の搬出側補助ローラ173を付設したので、処理済板材W2の搬出を円滑に行なえる。なお、ローラコンベヤ160、ストッパ170、搬出側補助ローラ173、搬入側補助ローラ183はいずれもすべての搬入径路Ka〜Knに跨って配置されているので、構成を簡素化しサイクルタイムを短縮することができる。   Furthermore, since the driven carry-out auxiliary roller 173 is attached to the stopper 170, the processed plate material W2 can be carried out smoothly. Since the roller conveyor 160, the stopper 170, the carry-out side auxiliary roller 173, and the carry-in side auxiliary roller 183 are all disposed across all the carry-in paths Ka to Kn, the configuration can be simplified and the cycle time can be shortened. it can.

(変形例)
図13に作動アームの作動変更例を示す。図13では作動アーム180a〜180nはギヤボックス187を介して支持軸182に連結している。支持軸182は支持軸固定梁183、183a間に回転自在に横架されている。支持軸182には、この支持軸182を正逆回転するための支持軸回転用モータ188(回転駆動源)が連結されている。ギヤボックス187内では、支持軸182に固定される駆動ギヤ187aと、この駆動ギヤ187aと噛合する従動ギヤ187dとを備えている。従動ギヤ187dは、作動アーム180a〜180nの短辺部185に固定される従動軸187bに、クラッチ187cを介して装着されている。
(Modification)
FIG. 13 shows an operation change example of the operating arm. In FIG. 13, the operating arms 180 a to 180 n are connected to the support shaft 182 via the gear box 187. The support shaft 182 is horizontally supported between the support shaft fixing beams 183 and 183a so as to be rotatable. The support shaft 182 is connected to a support shaft rotating motor 188 (rotation drive source) for rotating the support shaft 182 forward and backward. In the gear box 187, a drive gear 187a fixed to the support shaft 182 and a driven gear 187d meshing with the drive gear 187a are provided. The driven gear 187d is attached via a clutch 187c to a driven shaft 187b fixed to the short side portion 185 of the operating arms 180a to 180n.

この例における作動アーム180a〜180nの作動状態Q1(作動位置)と非作動状態Q2(非作動位置)との切換えは、図13(b)に示すように、支持軸回転用モータ188により行われる。この支持軸回転用モータ188を正回転若しくは逆回転させるとともに、クラッチ187cによる支持軸182(駆動ギヤ187a)から従動軸187b(従動ギヤ187d)への動力の接続、切断を制御して、各々の近接スイッチ10a〜10nに対応した搬入径路Ka〜Knの作動アーム180a〜180nを作動させる。つまり、いずれかの近接スイッチ10a〜10nが搬入不足状態の被処理板材W1’を検知したときに、対応する作動アーム180a〜180nは搬入不足状態の被処理板材W1’を搬送方向後方側(左側)から停止位置(ストッパ170位置)まで再搬入することができる。   Switching between the operating state Q1 (operating position) and the non-operating state Q2 (non-operating position) of the operating arms 180a to 180n in this example is performed by a support shaft rotating motor 188 as shown in FIG. . The support shaft rotating motor 188 is rotated forward or reverse, and the connection and disconnection of power from the support shaft 182 (drive gear 187a) to the driven shaft 187b (driven gear 187d) by the clutch 187c is controlled. The operation arms 180a to 180n of the carry-in paths Ka to Kn corresponding to the proximity switches 10a to 10n are operated. That is, when any one of the proximity switches 10a to 10n detects the processed board material W1 ′ that is in an insufficiently loaded state, the corresponding operating arm 180a to 180n moves the processed board material W1 ′ that is in an insufficiently loaded state to the rear side in the transport direction (left side). ) To a stop position (stopper 170 position).

このように、作動アーム180a〜180nを熱板130の搬送方向後端縁よりも後方に配置することによって、熱板130からはみ出るほど大きく搬入不足状態となった被処理板材W1’でも、作動アーム180a〜180nによって停止位置まで再搬入することができる。この例によれば、熱板130からのはみ出しによって処理済板材W2に成形不良(板厚の不揃い等)が発生することを回避して、製品歩留りをさらに向上できる。   As described above, by disposing the operation arms 180a to 180n behind the rear end edge in the conveyance direction of the hot plate 130, even if the processed plate material W1 ′ is large enough to protrude from the hot plate 130, the operation arm Reloading to the stop position is possible by 180a to 180n. According to this example, it is possible to avoid the occurrence of molding defects (such as uneven thickness of the plate) in the processed plate W2 due to the protrusion from the hot plate 130, thereby further improving the product yield.
