Description

本発明は、搬送方向と同方向の強度が軟弱な板状体の定規出し方法及び定規出し装置に関するものである。   The present invention relates to a ruler method and a ruler device for a plate-like body whose strength in the same direction as the conveying direction is weak.

従来、例えば特許文献１に開示される如く、搬送機構によって板状体を搬送する際に、搬送機構の搬送方向下手側に備えた定規部材に、板状体の先端を当接させて、該板状体の先端側の定規出しを行う技術が、種々の分野で汎用されているが、斯様に単純な構成によると、例えばベニヤ単板を繊維方向と直交方向に搬送する場合の如く、板状体の搬送方向と同方向の強度が軟弱な場合には、定規部材に当接した板状体の先端近傍が座屈する現象が発生し易く、適確な定規出しが行い得ない欠点があった。   Conventionally, as disclosed in, for example, Patent Document 1, when a plate-like body is conveyed by a conveyance mechanism, the tip of the plate-like body is brought into contact with a ruler member provided on the lower side in the conveyance direction of the conveyance mechanism, Although the technique of ruler on the tip side of the plate-like body is widely used in various fields, according to such a simple configuration, for example, when conveying a veneer veneer in a direction orthogonal to the fiber direction, If the strength in the same direction as the conveying direction of the plate-shaped body is soft, the phenomenon that the vicinity of the tip of the plate-shaped body in contact with the ruler member tends to buckle easily occurs, and accurate ruler cannot be performed. there were.

そこで、板状体の搬送に用いる搬送機構を左右各別に駆動可能に分離すると共に、板状体の先端が定規部材に当接する直前に、搬送機構の駆動を左右各別に断って、減速状態とした板状体の先端を、定規部材に当接させる構成を採ることにより、板状体の先端近傍の座屈を回避せんとする改良技術が、特許文献２に提案されている。   Therefore, the transport mechanism used for transporting the plate-like body is separated so that it can be driven separately on the left and right sides, and immediately before the front end of the plate-like body abuts on the ruler member, the drive of the transport mechanism is cut off on the left and right sides to reduce the deceleration state. Patent Document 2 proposes an improved technique for avoiding buckling in the vicinity of the tip of the plate-like body by adopting a configuration in which the tip of the plate-like body is brought into contact with the ruler member.

また更に、板状体の搬送に用いる搬送機構を駆動する駆動装置内へ、作動時にスリップを許容して駆動力を緩慢に供給する間歇駆動機構を介在させ、板状体の先端が定規部材に当接するよりも幾分前に、一旦搬送機構の駆動を断って、搬送機構を一時停止させてから、改めて搬送機構の駆動を再開し、作動直後に於ける、通常搬送速度以下の低速度にて、板状体の先端を、定規部材に当接させる構成を採ることにより、板状体の先端近傍の座屈を回避せんとする改良技術が、特許文献３に提案されている。
実公昭６０−３０００８号公報 特公昭６３−３７０１６号公報 特公平６−６２２３０号公報 Furthermore, an intermittent drive mechanism is provided in the drive device that drives the transport mechanism used for transporting the plate-like body, allowing slippage during operation and supplying the drive force slowly, and the tip of the plate-like body serves as the ruler member. Some time before the contact, the drive of the transport mechanism is temporarily cut off, the transport mechanism is temporarily stopped, and then the drive of the transport mechanism is restarted. Patent Document 3 proposes an improved technique for avoiding buckling in the vicinity of the tip of the plate-like body by adopting a configuration in which the tip of the plate-like body is brought into contact with the ruler member.
Japanese Utility Model Publication No. 60-30008 Japanese Patent Publication No.63-37016 Japanese Examined Patent Publication No. 6-62230

前記特許文献２・特許文献３に開示された改良技術は、いずれも、通常の搬送速度よりも低速度を以って、板状体の先端を、定規部材に当接させることにより、定規部材に対する板状体の先端の衝突を緩衝して、衝突に起因する座屈の回避を図るもので、先記特許文献１に開示された汎用技術に比べれば、相応に有効な技術ではあったが、斯様な定規出し手段に於て、板状体の重量の変動に伴う慣性力の増減や、当初の板状体の搬送姿勢の良否等に拘わりなく、常に適確な定規出しを行う為には、板状体の一部の先端が定規部材に当接した後も、少なくとも若干の駄目押し期間だけは（必要に応じては、搬送機構と板状体とが比較的容易にスリップし得る構成を採って、永続的に）、板状体の搬送を継続することが必要であることから、搬送方向と同方向の強度が通例よりも一段と軟弱な板状体が混在した場合には、衝突以外の要因による座屈、即ち、前記搬送の継続に起因して座屈が発生し易い欠陥があり、適確な定規出しを恒常的に行うには未だ不十分な実状であった。   The improved techniques disclosed in Patent Document 2 and Patent Document 3 both have a ruler member by bringing the tip of the plate-like body into contact with the ruler member at a lower speed than the normal conveying speed. It is intended to buffer the collision of the tip of the plate-like body against the buckle and avoid buckling caused by the collision, and compared with the general-purpose technique disclosed in Patent Document 1, it was a technique that was correspondingly effective. In such a ruler means, in order to always perform an accurate ruler regardless of the increase or decrease of the inertial force accompanying the fluctuation of the weight of the plate-like body, the quality of the initial conveyance posture of the plate-like body, etc. Even after the front end of a part of the plate-like body comes into contact with the ruler member, the conveying mechanism and the plate-like body can slip relatively easily for at least some useless pressing periods (if necessary. Since it is necessary to continue transporting the plate-like body permanently, adopting the configuration In the case where a plate-like body whose strength in the same direction as the usual direction is much weaker than usual, there is a defect in which buckling is likely to occur due to buckling due to factors other than collision, that is, due to continuation of the conveyance. However, the situation was still insufficient to make an accurate ruler constantly.

本発明は、前記改良技術の欠陥をも補完すべく開発したものであり、具体的には、搬送機構の搬送方向下手側に備えた定規部材に、搬送機構によって搬送する板状体の先端を当接させて、板状体の定規出しを行うに際し、定規部材に当接した板状体の先端近傍が所定限度以上の高さに座屈した場合に限っては、板状体の先端が、定規部材の位置から搬送機構の搬送方向上手側へ所定距離隔てた、所定の隔離位置に至るまで、板状体を一旦逆向きに搬送すべく、搬送機構を逆転駆動させた後に、搬送機構を停止させ、次いで、板状体を前記所定距離だけ搬送するに足る短期間だけ、再び搬送機構を正転駆動させることによって、板状体の先端を定規部材に当接させ、定規出しを行うことを特徴とする搬送方向と同方向の強度が軟弱な板状体の定規出し方法（請求項１）を提案する。   The present invention has been developed to compensate for the defects of the improved technology. Specifically, the tip of the plate-like body to be transported by the transport mechanism is attached to the ruler member provided on the lower side in the transport direction of the transport mechanism. When the plate-shaped body is ruled out by contacting the plate-shaped body, the tip of the plate-shaped body is only bent if the vicinity of the tip of the plate-shaped body that is in contact with the ruler member is buckled to a height exceeding a predetermined limit. The transport mechanism is reversely driven so as to transport the plate-like body once in the reverse direction until it reaches a predetermined isolation position that is spaced a predetermined distance from the position of the ruler member toward the upper side in the transport direction of the transport mechanism. Then, the conveying mechanism is driven to rotate in the normal direction again for a short period sufficient to convey the plate-like body by the predetermined distance, thereby bringing the tip of the plate-like body into contact with the ruler member and performing the ruler A plate-like body having a weak strength in the same direction as the transport direction is characterized. Proposes a method (claim 1) out.

また、前記定規出し方法の実施に用いる装置として、板状体を搬送する搬送機構と、搬送機構の搬送方向下手側に位置する定規部材とを備え、更に板状体の先端が定規部材の位置に到達したか否かを検出する到達検出部材と、定規部材に当接した板状体の先端近傍が所定限度以上の高さに座屈したか否かを判別する座屈判別部材と、前記到達検出部材の検出信号及び座屈判別部材の判別信号に基づいて、定規部材に当接した板状体の先端近傍が所定限度以上の高さに座屈した場合に限っては、板状体の先端が、定規部材の位置から搬送機構の搬送方向上手側へ所定距離隔てた、所定の隔離位置に至るまで、板状体を一旦逆向きに搬送すべく、搬送機構を逆転駆動させた後に、搬送機構を停止させ、次いで、板状体を前記所定距離だけ搬送するに足る短期間だけ、再び搬送機構を正転駆動させるように、搬送機構の作動を制御する制御機構とを備えたことを特徴とする定規出し装置（請求項２）と、ベルトコンベアを搬送機構として用いて成る請求項２記載の定規出し装置（請求項３）と、ロールコンベアを搬送機構として用いて成る請求項２記載の定規出し装置（請求項４）とを提案する。   Further, as an apparatus used for carrying out the ruler extraction method, the apparatus includes a conveyance mechanism that conveys the plate-like body, and a ruler member that is located on the lower side in the conveyance direction of the conveyance mechanism, and the tip of the plate-like body is located at the position of the ruler member. An arrival detection member that detects whether or not the belt has reached the edge, and a buckling determination member that determines whether or not the vicinity of the tip of the plate-like body that is in contact with the ruler member is buckled to a height that is greater than or equal to a predetermined limit; Based on the detection signal of the arrival detection member and the discrimination signal of the buckling discrimination member, the plate-like body only when the vicinity of the tip of the plate-like body abutting on the ruler member buckles to a height above a predetermined limit. After the transport mechanism is driven in reverse to once transport the plate-like member in the reverse direction until the tip of the plate reaches a predetermined isolation position that is a predetermined distance away from the position of the ruler member toward the upper side in the transport direction of the transport mechanism , Stop the transport mechanism, and then transport the plate-like body for the predetermined distance A ruler device (Claim 2) including a control mechanism for controlling the operation of the transport mechanism so that the transport mechanism is driven to rotate forward again for a short period of time, and a belt conveyor as the transport mechanism. The ruler-out device according to claim 2 (Claim 3) used and the ruler-out device according to Claim 2 (Claim 4) using a roll conveyor as a transport mechanism are proposed.

前記請求項１に係る発明の定規出し方法によると、原則的には、先記汎用技術や改良技術に準じて、常法通りの適確性で定規出しが行い得るのは勿論のこと、仮に何等かの要因によって、例外的に、板状体の先端近傍が所定限度以上の高さに座屈した場合には、先述の如く板状体を一旦逆向きに搬送することにより、座屈した板状体の先端近傍を元通りに平坦化させ、次いで、決して再び座屈が発生することの無い距離だけ、板状体を正規の搬送方向に搬送することによって、板状体の先端を定規部材に当接させるので、座屈が確実に解消される結果となり、総じて、適確な定規出しを恒常的に行うことが可能となる。   According to the ruler determination method of the invention according to the first aspect, in principle, ruler can be performed with appropriate accuracy as usual, according to the general-purpose technique and the improved technique described above. Exceptionally due to these factors, when the vicinity of the tip of the plate-like body buckles to a height exceeding a predetermined limit, the plate-like body is once transported in the reverse direction as described above, so that the buckled plate is By flattening the vicinity of the tip of the plate as it was, and then transporting the plate in the normal transport direction by a distance that never causes buckling again, the tip of the plate is moved to the ruler member. As a result, the buckling is surely eliminated, and as a whole, it is possible to perform accurate ruler constantly.

また、請求項２・請求項３及び請求項４に係る発明の定規出し装置を用いれば、前記定規出し方法を支障なく実施することができる。   In addition, if the ruler dispensing apparatus according to the inventions according to claims 2, 3 and 4 is used, the ruler dispensing method can be carried out without any trouble.

以下、本発明を図面に例示した実施の一例と共に更に詳述するが、装置を構成する機構や部材の形態については、図示した形態に限定するものではなく、既知の種々の形態を含め適宜設計変更して差支えない。因に、板状体と係合する搬送機構の接触面の摩擦係数については、定規出しの容易性からすると、小さいほうが好ましいが、搬送の適確性からすると、過剰に小さいのは好ましくなく、総合的に勘案すると、搬送に支障が生じない範囲内で可及的に小さいのが望ましい。また、定規部材の接触面の摩擦係数についても、同様に小さいほうが好ましいが、先記特許文献１に開示されるロール状の定規部材の如く、回転自在式の定規部材であれば、回転抵抗を可及的に小さくする方がより適切である。   Hereinafter, the present invention will be described in further detail with an example of the embodiment illustrated in the drawings. However, the forms of the mechanisms and members constituting the apparatus are not limited to the illustrated forms, and are appropriately designed including various known forms. It can be changed. Incidentally, the friction coefficient of the contact surface of the transport mechanism that engages with the plate-like body is preferably smaller from the viewpoint of ease of ruler, but it is not preferable that it is excessively small from the viewpoint of appropriateness of transport. In view of the above, it is desirable that it is as small as possible within a range in which the conveyance is not hindered. Further, the friction coefficient of the contact surface of the ruler member is preferably preferably similarly small, but if it is a rotatable ruler member such as a roll-like ruler member disclosed in Patent Document 1, the rotational resistance is reduced. It is more appropriate to make it as small as possible.

FIG. 6 is a side operation explanatory diagram of the ruler dispensing device illustrated in FIG. In the figure, A is a belt conveyor that constitutes a transport mechanism, which is composed of a plurality of transport belts 1a, pulleys 1b, a rotating shaft 1c, a rotary encoder 1d, etc. In principle, it is driven in the normal direction in the direction indicated by the arrow a through a drive source 2 consisting of a servo motor, clutch & brake motor, etc., and has a rectangular plate shape whose strength in the same direction as the conveying direction is soft. The body 3 is transported in the direction indicated by the arrow a. However, only in a specific required time, the body 3 is driven to rotate in the reverse direction indicated by the arrow b for only a short period of time, and the plate-like body 3 is moved in the direction indicated by the arrow b. Make it reverse.

Ｂは、定規部材を構成する起伏式のストッパであって、前記ベルトコンベアＡの搬送方向と直交方向に配設された左右一対の止め板４ａ・４ｂ、回動軸４ｃ等から成り、後述する制御機構Ｅの制御を得て、常態に於ては、流体シリンダ等から成る作動部材５を介して、実線で示す位置に起立せしめられ、ベルトコンベアＡによって搬送される板状体３の先端に当接して、該板状体３の搬送を阻止し、板状体３の先端側を定規出しする。また、制御機構Ｅの制御を得て、所要時に、作動部材５を介して、点線で示す位置に転倒せしめられる。   B is an up-and-down stopper that constitutes a ruler member, and includes a pair of left and right stop plates 4a and 4b, a rotation shaft 4c, and the like disposed in a direction orthogonal to the conveying direction of the belt conveyor A, which will be described later. Under the control of the control mechanism E, in the normal state, it is erected at the position indicated by the solid line through the operation member 5 composed of a fluid cylinder or the like, and is fed to the tip of the plate-like body 3 conveyed by the belt conveyor A. Abutting, the conveyance of the plate-like body 3 is prevented, and the front end side of the plate-like body 3 is ruled out. In addition, the control mechanism E is controlled, and when necessary, the control mechanism E is overturned to the position indicated by the dotted line via the operation member 5.

Ｃは、到達検出部材を構成する非接触式の到達検出器であって、前記ストッパＢを構成する左右一対の止め板４ａ・４ｂの夫々の近傍に配設された２個の反射型光センサ６ａ、６ｂから成り、板状体３の先端が、ストッパＢを構成する左右一対の止め板４ａ・４ｂの位置に到達したか否かを各別に検出して、後述する制御機構Ｅに検出信号を発信すると共に、一旦止め板４ａ・４ｂに当接した板状体３の先端が、板状体３の逆送に伴って、止め板４ａ・４ｂから離れた場合には、検出信号の発信を停止する。   C is a non-contact type arrival detector constituting an arrival detection member, and two reflection type optical sensors disposed in the vicinity of the pair of left and right stop plates 4a and 4b constituting the stopper B 6a and 6b, each of which detects whether or not the tip of the plate-like body 3 has reached the position of the pair of left and right stop plates 4a and 4b constituting the stopper B, and sends a detection signal to the control mechanism E described later. When the tip of the plate-like body 3 once abutting against the stop plates 4a and 4b is separated from the stop plates 4a and 4b due to the reverse feed of the plate-like body 3, a detection signal is transmitted. To stop.

Ｄは、座屈判別部材を構成する非接触式の座屈判別器であって、前記ベルトコンベアＡの搬送ベルト１ａよりも所望高さだけ上方の左右両側部であり、且つ前記ストッパＢよりも搬送方向の若干上手側に在って、ストッパＢに対して幾分斜めの非平行状に配設された投光管７ａと受光管７ｂとから成り、ストッパＢに当接した板状体３の先端近傍が所定限度以上の高さに座屈したか否かを判別して、後述する制御機構Ｅに判別信号を発信する。   D is a non-contact type buckling discriminator constituting a buckling discriminating member, which is on the left and right sides above the conveying belt 1a of the belt conveyor A by a desired height, and more than the stopper B. A plate-like body 3 which is located slightly on the upper side in the transport direction and which is composed of a light projecting tube 7a and a light receiving tube 7b which are arranged slightly obliquely with respect to the stopper B and is in contact with the stopper B. It is determined whether or not the vicinity of the tip of the arm has buckled to a height above a predetermined limit, and a determination signal is transmitted to the control mechanism E described later.

Ｅは、制御機構であって、原則的には、板状体３を矢印ａで示す向きに搬送し、その先端を定規部材であるストッパＢに当接させて、板状体３の先端側の定規出しを行うべく、駆動源２を介して、ベルトコンベアＡを図示矢印ａで示す向きに正転駆動させるが、前記到達検出器Ｃの検出信号及び座屈判別器Ｄの判別信号に基づいて、ストッパＢに当接した板状体３の先端近傍が所定限度以上の高さに座屈した場合に限っては、板状体３の先端が、ストッパＢの位置ＵからベルトコンベアＡの搬送方向上手側へ所定距離Ｌ隔てた、所定の隔離位置Ｖに至るまで、板状体３を一旦逆向きに搬送すべく、ベルトコンベアＡを逆転駆動させた後に、ベルトコンベアＡを停止させ、次いで、板状体３を前記所定距離Ｌだけ搬送するに足る短期間だけ、再びベルトコンベアＡを正転駆動させるように、ベルトコンベアＡの作動を制御する。また併せて、常態に於ては、前記ストッパＢを実線で示す位置に起立させるべく、作動部材５の作動を制御すると共に、必要に応じて、ストッパＢを点線で示す位置に転倒させるべく、作動部材５の作動を制御する。   E is a control mechanism which, in principle, transports the plate-like body 3 in the direction indicated by the arrow a and makes its tip abut against a stopper B, which is a ruler member, so that the tip side of the plate-like body 3 The belt conveyor A is driven to rotate forward in the direction indicated by the arrow a through the drive source 2 in order to carry out the ruler, but based on the detection signal of the arrival detector C and the discrimination signal of the buckling discriminator D Thus, only when the vicinity of the tip of the plate-like body 3 in contact with the stopper B is buckled to a height above a predetermined limit, the tip of the plate-like body 3 is moved from the position U of the stopper B to the belt conveyor A. In order to transport the plate-like body 3 in the reverse direction once until it reaches a predetermined isolation position V separated by a predetermined distance L toward the upper side in the transport direction, after the belt conveyor A is driven in reverse, the belt conveyor A is stopped, Subsequently, the plate-shaped body 3 is re-recovered for a short period sufficient to transport the predetermined distance L. The belt conveyor A so as to forward drive, controls the operation of the belt conveyor A. At the same time, under normal conditions, the operation of the operating member 5 is controlled so that the stopper B is raised at the position indicated by the solid line, and if necessary, the stopper B is turned over to the position indicated by the dotted line. The operation of the operation member 5 is controlled.

本発明に係る定規出し装置は、例えば述上の如く構成するものであって、図１・図２に例示する如く、ベルトコンベアＡによって板状体３を矢印ａで示す向きに搬送すると、やがて図３に例示する如く、板状体３の先端がストッパＢを構成する左右一対の止め板４ａ・４ｂの双方に当接することによって、板状体３の先端側が定規出しされるが、その際、通常の多くの場合は、板状体３の先端近傍は所定限度以上の高さに座屈せず、座屈判別器Ｄから判別信号が発信されないので、定規出しが適確に行われたことが判明する。そこで、制御機構Ｅは、図４に例示する如く、ストッパＢを構成する左右一対の止め板４ａ・４ｂを実線で示す位置に転倒させるよう、作動部材５の作動を制御し、ベルトコンベアＡによる板状体３の搬送を継続（再開）させる。   The ruler according to the present invention is configured as described above, for example, and when the plate-like body 3 is conveyed in the direction indicated by the arrow a by the belt conveyor A as illustrated in FIGS. As illustrated in FIG. 3, the front end of the plate-like body 3 is ruled out by the front end of the plate-like body 3 coming into contact with both the left and right pair of stop plates 4 a and 4 b constituting the stopper B. In many cases, the vicinity of the tip of the plate-like body 3 does not buckle to a height higher than a predetermined limit, and the discrimination signal is not transmitted from the buckling discriminator D. Becomes clear. Therefore, as illustrated in FIG. 4, the control mechanism E controls the operation of the operation member 5 so as to cause the pair of left and right stop plates 4 a and 4 b constituting the stopper B to fall to the position indicated by the solid line. The conveyance of the plate-like body 3 is continued (resumed).

因に、板状体の先端側が定規に当接した後の搬送機構の制御については、従前と同様に所望の態様を採ることが可能である。即ち、板状体の先端側が定規部材に当接してからも、若干の駄目押し期間だけは搬送機構の駆動を継続した後に、図３に例示する如く、一旦、駆動を休止する態様の他に、搬送機構と板状体とが比較的容易にスリップし得るようにして、後述する例外的な場合を除いては、連続的に駆動を継続する態様を採っても差支えない。但し、連続的に駆動を継続する態様を採る場合には、搬送速度よりも速くストッパを転倒させるのが好ましい。また、後述する如く、定規出しを終えた板状体を、搬送機構の搬送方向と異なる方向へ移送する構成を採る場合には、搬送機構と板状体との係合の均等化からして、一旦、搬送機構の駆動を休止する態様を採るのが好ましい。   Incidentally, as for the control of the transport mechanism after the front end side of the plate-like body comes into contact with the ruler, it is possible to adopt a desired mode as before. That is, after the leading end side of the plate-like body abuts on the ruler member, after continuing the driving of the transport mechanism only for a slight period of depression, as shown in FIG. It is possible to adopt a mode in which the conveyance mechanism and the plate-like body can slip relatively easily and the driving is continuously continued except in exceptional cases described later. However, when adopting a mode in which the driving is continuously continued, it is preferable that the stopper is toppled over at a speed higher than the conveyance speed. In addition, as will be described later, when adopting a configuration in which the plate-like body that has finished the ruler is transferred in a direction different from the conveyance direction of the conveyance mechanism, the engagement between the conveyance mechanism and the plate-like body is equalized. It is preferable to adopt a mode in which the driving of the transport mechanism is temporarily stopped.

また一方、何等かの原因によって、仮に図５に例示する如く、板状体３の先端近傍が所定限度以上の高さに座屈したとすると、座屈判別器Ｄから判別信号が発信されるので、制御機構Ｅは、図６に例示する如く、板状体３の先端が、ストッパＢの位置ＵからベルトコンベアＡの搬送方向上手側へ所定距離Ｌ隔てた、所定の隔離位置Ｖに至るまで、板状体３を一旦逆向きに搬送するように、ベルトコンベアＡを逆転駆動させた後に、ベルトコンベアＡを停止させ、次いで、図７に例示する如く、板状体３を前記所定距離Ｌだけ搬送するに足る短期間だけ、再びベルトコンベアＡを正転駆動させるように、駆動源２を介して、ベルトコンベアＡの作動を制御するので、この場合も結果的に、定規出しが適確に行われる。そこで更に、制御機構Ｅは、図８に例示する如く、ストッパＢを構成する左右一対の止め板４ａ・４ｂを実線で示す位置に転倒させるよう、作動部材５の作動を制御すると共に、ベルトコンベアＡによる板状体３の搬送を再開させるよう、駆動源２の作動を制御する。   On the other hand, if for some reason, as illustrated in FIG. 5, the vicinity of the tip of the plate-like body 3 is buckled to a height exceeding a predetermined limit, a discrimination signal is transmitted from the buckling discriminator D. Therefore, as illustrated in FIG. 6, the control mechanism E reaches the predetermined isolation position V at which the tip of the plate-like body 3 is separated from the position U of the stopper B by a predetermined distance L toward the upper side in the conveying direction of the belt conveyor A. The belt conveyor A is reversely driven so as to once convey the plate-like body 3 in the reverse direction, and then the belt conveyor A is stopped. Then, as illustrated in FIG. 7, the plate-like body 3 is moved to the predetermined distance. Since the operation of the belt conveyor A is controlled via the drive source 2 so that the belt conveyor A is driven to rotate in the normal direction again only for a short period sufficient to convey only L, the ruler is also suitable as a result in this case. Certainly done. Therefore, as illustrated in FIG. 8, the control mechanism E controls the operation of the operating member 5 so as to cause the pair of left and right stop plates 4a and 4b constituting the stopper B to fall to the position indicated by the solid line, and to convey the belt conveyor. The operation of the drive source 2 is controlled so that the conveyance of the plate-like body 3 by A is resumed.

尚、述上の如く板状体を所定距離だけ逆向きに搬送してから、再び所定距離だけ正規の方向に搬送するに際し、必要となる搬送機構の駆動量を制御する手段としては、例えば制御機構内に、到達検出器の検出信号の有無に関連して作動するタイマ等の時限機器を備えて、時間で以って制御する手段も挙げられるが、精度の良さからすると、前記実施例の如く、搬送機構（ベルトコンベア）にロータリエンコダ等のセンサを付設して、搬送機構の実動距離に基づいて制御する手段の方が、一段と適切であり、或は図示は省略したが、前記実施例の到達検出器（反射型光センサ）と同種の逆送検出器を、所定の隔離位置に関連させて備え、該逆送検出器の検出信号に基づいて制御する手段でも差支えない。   As described above, as a means for controlling the driving amount of the transport mechanism required when transporting the plate-like body in the reverse direction by a predetermined distance and then transporting it in the normal direction again by a predetermined distance, for example, control The mechanism includes a timed device such as a timer that operates in relation to the presence or absence of the detection signal of the arrival detector, and includes means for controlling by time. As described above, the means for attaching a sensor such as a rotary encoder to the transport mechanism (belt conveyor) and controlling it based on the actual moving distance of the transport mechanism is more appropriate, or omitted from the illustration. A reverse detector of the same type as the arrival detector (reflection type optical sensor) of the embodiment may be provided in association with a predetermined isolation position, and a means for controlling based on the detection signal of the reverse detector may be used.

また、前記実施例に於ては、定規出しを終えた板状体を、再び当初の搬送方向と同方向へ搬送する構成としたが、定規出しを終えた板状体の移送方向は、前記実施例の態様に限るものではなく、図示は省略したが、例えば前記実施例に於けるベルトコンベアのベルトと交差する位置に、ロールコンベアを昇降自在に備え、ベルトコンベアのベルトの上方に上昇させたロールコンベアに定規出しを終えた板状体を移乗させて、ベルトコンベアの搬送方向と直交方向に板状体を移送する態様、或は例えば前記実施例に於けるベルトコンベアの上方に、吸着移載機構を昇降及び旋回自在に備え、定規出しを終えた板状体を吸着移載機構によって吸着上昇させると共に、吸着移載機構を１８０度旋回させて、ベルトコンベアの反対側（吸着移載機構を間に介在させた反対側）に設定した堆積位置に板状体を移載する態様等々、既知の種々の態様を含め適宜設計変更して差支えない。   Further, in the embodiment, the plate-like body after finishing the ruler is configured to be conveyed again in the same direction as the original conveyance direction. The present invention is not limited to the embodiment, and is not shown. However, for example, a roll conveyor is provided at a position intersecting with the belt of the belt conveyor in the above embodiment so as to be raised and lowered, and is raised above the belt of the belt conveyor. A plate-shaped body that has finished ruler transfer is transferred to a roll conveyor, and the plate-shaped body is transferred in a direction perpendicular to the conveying direction of the belt conveyor, or, for example, adsorbed above the belt conveyor in the above embodiment The transfer mechanism is provided so that it can be moved up and down and swiveled, and the plate-like body that has been ruled out is sucked and raised by the suction transfer mechanism, and the suction transfer mechanism is swung 180 degrees to the opposite side of the belt conveyor (suction transfer) Mechanism The set deposition position on the opposite side) which is interposed so manner of transferring the plate-like body, no problem was appropriately modified by including various known aspects to.

また、述上の如く、定規出しを終えた板状体の移送方向を、当初の搬送方向と同方向以外の方向に設定する場合には、必ずしも定規部材を搬送機構の下方へ退避させる必要はなく、後述する異なる実施例の如く、定置型の定規部材を用いることも可能であるが、たとえ定規出しを終えた板状体の移送方向を、当初の搬送方向と同方向以外の方向に設定する場合であっても、必要に応じては、定規部材を退避可能に備えて、定規出しを終えた板状体を移送する際の、板状体と定規部材との無用な接触を回避するようにしても差支えない。   In addition, as described above, when setting the transport direction of the plate-shaped body after finishing the ruler to a direction other than the same direction as the original transport direction, it is not always necessary to retract the ruler member below the transport mechanism. However, it is possible to use a stationary ruler member as in different embodiments to be described later, but the transport direction of the plate-like body after finishing the ruler is set to a direction other than the same direction as the original transport direction. Even if it is a case, if necessary, the ruler member can be retracted to avoid unnecessary contact between the plate-like body and the ruler member when the plate-like body that has been ruled out is transferred. Even so, there is no problem.

また、前記実施例に於ては、搬送機構の搬送形態・搬送速度について格別に規定していないが、必要に応じては、先記特許文献２・特許文献３に開示される技術の併用も可能であって、例えば搬送機構を左右各別に駆動可能に分離すると共に、板状体の先端が定規部材に当接する直前に、搬送機構の駆動を左右各別に断って、減速状態とした板状体の先端を、定規部材に当接させたり、或は例えば板状体の先端が定規部材に当接するよりも幾分前に、一旦搬送機構の駆動を断って、搬送機構を一時停止させてから、改めて搬送機構の駆動を再開し、作動直後に於ける、通常搬送速度以下の低速度にて、板状体の先端を、定規部材に当接させたりする構成を付加しても差支えない。   In the above-described embodiments, the transport mode and transport speed of the transport mechanism are not particularly defined. However, if necessary, the technology disclosed in Patent Documents 2 and 3 may be used in combination. For example, the transport mechanism is separated so that it can be driven separately on the left and right sides, and immediately before the front end of the plate-like body comes into contact with the ruler member, the drive of the transport mechanism is cut off on the left and right sides to reduce the speed. The front end of the body is brought into contact with the ruler member, or for example, some time before the front end of the plate-like body comes into contact with the ruler member, the drive of the transport mechanism is temporarily turned off and the transport mechanism is temporarily stopped. Therefore, it is possible to add a configuration in which the driving of the transport mechanism is restarted and the tip of the plate-like body is brought into contact with the ruler member at a low speed equal to or less than the normal transport speed immediately after the operation. .

次に、図９は、菱形の板状体の定規出しに用い得る、本発明に係る定規出し装置の異なる実施例の側面概略説明図であり、図１０は、図９に例示した定規出し装置の平面概略説明図であである。また、図１１乃至図１５は、図９及び図１０に例示した定規出し装置の側面作動説明図である。図中、Ａ１は、搬送機構を構成するロールコンベアであって、複数本の搬送ロール８ａ、プーリ８ｂ、連結ベルト８ｃ、ロータリエンコダ８ｄ等から成り、後述する制御機構Ｅ１の制御を得て、原則的には、サーボモータ・クラッチ＆ブレーキ付モータ等から成る駆動源９を介して、図示矢印ａで示す向きに正転駆動せしめられ、搬送方向と同方向の強度が軟弱な菱形の板状体３ａを矢印ａで示す向きに搬送するが、特定所要時に限っては、例外的に短期間だけ、図示矢印ｂで示す向きに逆転駆動せしめられ、板状体３ａを矢印ｂで示す向きに逆送させる。因に、図示例の板状体は、矩形のベニヤ単板の複数枚を予め縦矧してから菱形に成形したものである。   Next, FIG. 9 is a schematic side view of a different embodiment of the ruler device according to the present invention, which can be used for the ruler of the diamond-shaped plate, and FIG. 10 is the ruler device illustrated in FIG. It is a plane schematic explanatory drawing. 11 to 15 are side operation explanatory views of the ruler dispensing apparatus illustrated in FIGS. 9 and 10. In the figure, A1 is a roll conveyor that constitutes a transport mechanism, which consists of a plurality of transport rolls 8a, pulleys 8b, a connecting belt 8c, a rotary encoder 8d, etc. In principle, it is driven in the normal direction in the direction indicated by an arrow a through a drive source 9 consisting of a servo motor, a motor with a clutch and a brake, etc., and has a rhombic plate shape whose strength in the same direction as the conveying direction is weak. The body 3a is transported in the direction indicated by the arrow a. However, only in a specific required period, the body 3a is exceptionally driven in the reverse direction indicated by the arrow b for only a short period, and the plate-like body 3a is moved in the direction indicated by the arrow b. Make it reverse. In the meantime, the plate-like body in the illustrated example is formed by pre-verting a plurality of rectangular veneer single plates and then forming a rhombus.

Ｂ１は、定規部材を構成する回転式のストッパであって、前記ロールコンベアＡ１の搬送方向の下手側へ回転自在に定置配設された定規ロール１０から成り、ロールコンベアＡ１によって搬送される板状体３ａの先端に当接して、該板状体３ａの搬送を阻止し、板状体３ａの先端側を定規出しする。   B1 is a rotary stopper that constitutes a ruler member, and is composed of a ruler roll 10 that is fixedly disposed rotatably on the lower side in the conveying direction of the roll conveyor A1, and is a plate-like shape that is conveyed by the roll conveyor A1. Abutting on the tip of the body 3a, the conveyance of the plate-like body 3a is prevented, and the tip side of the plate-like body 3a is ruled out.

Ｃ１は、到達検出部材を構成する非接触式の到達検出器であって、前記ストッパＢ１を構成する定規ロール１０の近傍に配設された反射型光センサ１１から成り、板状体３ａの先端が、ストッパＢ１を構成する定規ロール１０の位置に到達したか否かを検出して、後述する制御機構Ｅ１に検出信号を発信すると共に、一旦定規ロール１０に当接した板状体３ａの先端が、板状体３ａの逆送に伴って、定規ロール１０から離れた場合には、検出信号の発信を停止する。   C1 is a non-contact type arrival detector that constitutes an arrival detection member, and comprises a reflection type photosensor 11 disposed in the vicinity of the ruler roll 10 that constitutes the stopper B1, and the tip of the plate-like body 3a. Detects whether or not the position of the ruler roll 10 constituting the stopper B1 has been reached, and sends a detection signal to the control mechanism E1 described later, and also the tip of the plate-like body 3a once abutting against the ruler roll 10 However, when it leaves | separates from the ruler roll 10 with reverse feed of the plate-shaped body 3a, transmission of a detection signal is stopped.

Ｄ１は、座屈判別部材を構成する接触式の座屈判別器であって、前記ロールコンベアＡ１の搬送ロール８ａよりも所望高さだけ上方であり、且つ前記ストッパＢ１よりも搬送方向の若干上手側に位置するリミットスィッチ１２から成り、ストッパＢ１に当接した板状体３ａの先端近傍が所定限度以上の高さに座屈したか否かを判別して、後述する制御機構Ｅに判別信号を発信する。 D1 is a contact-type buckling discriminator that constitutes a buckling discriminating member, which is a desired height above the transport roll 8a of the roll conveyor A1 and slightly better in the transport direction than the stopper B1. It is determined whether or not the vicinity of the front end of the plate-like body 3a that is in contact with the stopper B1 is buckled to a height that exceeds a predetermined limit, and a determination signal is sent to the control mechanism E described later. To send.

Ｅ１は、制御機構であって、原則的には、板状体３ａを矢印ａで示す向きに搬送し、その先端をストッパＢ１に当接させて、板状体３ａの先端側の定規出しを行うべく、駆動源９を介して、ロールコンベアＡ１を図示矢印ａで示す向きに正転駆動させると共に、到達検出器Ｃ１の検出信号に基づき、ストッパＢ１に板状体３ａの先端が当接した場合には、板状体３ａの片方の側面が、後述するストップガイドＦに確実に当接するまで、板状体３ａが横滑りするに足る時間的な余裕を持って、ロールコンベアＡ１の駆動を停止させる。また、到達検出器Ｃ１の検出信号及び座屈判別器Ｄ１の判別信号に基づいて、ストッパＢ１に当接した板状体３ａの先端近傍が所定限度以上の高さに座屈した場合に限っては、板状体３ａの先端が、ストッパＢ１の位置ＸからロールコンベアＡ１の搬送方向上手側へ所定距離Ｌ１隔てた、所定の隔離位置Ｙに至るまで、板状体３ａを一旦逆向きに搬送すべく、ロールコンベアＡ１を逆転駆動させた後に、ロールコンベアＡ１を停止させ、次いで、板状体３ａを前記所定距離Ｌ１だけ搬送するに足る短期間だけ、再びロールコンベアＡ１を正転駆動させるように、ロールコンベアＡ１の作動を制御する。   E1 is a control mechanism. In principle, the plate-like body 3a is transported in the direction indicated by the arrow a, and its tip is brought into contact with the stopper B1, so that the ruler on the tip side of the plate-like body 3a is regulated. In order to do this, the roll conveyor A1 is driven to rotate forward in the direction indicated by the arrow a through the drive source 9, and the tip of the plate-like body 3a comes into contact with the stopper B1 based on the detection signal of the arrival detector C1. In this case, the drive of the roll conveyor A1 is stopped with sufficient time to allow the plate-like body 3a to slide sideways until one side surface of the plate-like body 3a comes into contact with the stop guide F described later. Let Further, based on the detection signal of the arrival detector C1 and the discrimination signal of the buckling discriminator D1, only when the vicinity of the tip of the plate-like body 3a in contact with the stopper B1 is buckled to a height exceeding a predetermined limit. The plate-like body 3a is once transported in the reverse direction until the tip of the plate-like body 3a reaches a predetermined isolation position Y, which is separated by a predetermined distance L1 from the position X of the stopper B1 toward the upper side in the conveyance direction of the roll conveyor A1. Therefore, after the roll conveyor A1 is driven to rotate in the reverse direction, the roll conveyor A1 is stopped, and then the roll conveyor A1 is driven to rotate forward again for a short period sufficient to transport the plate-like body 3a by the predetermined distance L1. Then, the operation of the roll conveyor A1 is controlled.

Ｆは、補助定規部材を兼ねる規制部材を構成する回転式のストップガイドであって、前記ロールコンベアＡ１の片方の側部に在って、ロールコンベアＡ１の搬送方向と平行状に、而も夫々回転自在に定置配設された２個のガイドロール１３・１３ａから成り、ロールコンベアＡ１によって搬送される板状体３ａの先端が、ストッパＢ１に当接するのに伴って、板状体３ａが前記ロールコンベアＡ１の片方の側部へ横滑りした際に、板状体３ａの片方の側面に当接して、板状体３ａがロールコンベアＡ１の片方の側部へ横滑りすることを、一定限度以内に留めるよう規制する。   F is a rotary stop guide that constitutes a regulating member that also serves as an auxiliary ruler member, and is located on one side of the roll conveyor A1 and parallel to the conveying direction of the roll conveyor A1, respectively. The plate-shaped body 3a is composed of two guide rolls 13 and 13a that are rotatably arranged, and the plate-shaped body 3a is brought into contact with the stopper B1 as the tip of the plate-shaped body 3a conveyed by the roll conveyor A1 comes into contact with the stopper B1. When sliding to one side of the roll conveyor A1, the plate 3a comes into contact with one side of the plate-like body 3a and slides to one side of the roll conveyor A1 within a certain limit. Regulate to stop.

本発明に係る定規出し装置は、例えば斯様に構成することも可能であり、図９・図１０に例示する如く、ロールコンベアＡ１によって板状体３ａを矢印ａで示す向きに搬送すると、やがて図１１に例示する如く、板状体３ａの先端がストッパＢ１を構成する定規ロール１０に当接するが、板状体３ａの片方の側面とストップガイドＦを構成する２個のガイドロール１３・１３ａとの間に隙間がある限り、板状体３ａは該位置に留まらず、更に僅かだけ矢印ａで示す向きに継続搬送されつつ、ロールコンベアＡ１の片方の側部へ横滑りする。そして、図１２に例示する如く、板状体３ａの先端が定規ロール１０に当接し、而も板状体３ａの片方の側面が２個のガイドロール１３・１３ａに当接する状態に至ると、板状体３ａがそれ以上搬送されることはなく、先端側が定規出しされるので、制御機構Ｅ１の制御を得て、ロールコンベアＡ１の駆動が停止される。その際、通常の多くの場合は、板状体３ａの先端近傍は所定限度以上の高さに座屈せず、座屈判別器Ｄ１から判別信号が発信されないので、定規出しが適確に行われたことが判明する。   The ruler dispensing apparatus according to the present invention can be configured as such, for example, and when the plate-like body 3a is conveyed in the direction indicated by the arrow a by the roll conveyor A1 as illustrated in FIGS. 9 and 10, eventually. As illustrated in FIG. 11, the tip of the plate-like body 3a abuts on the ruler roll 10 constituting the stopper B1, but one side surface of the plate-like body 3a and the two guide rolls 13 and 13a constituting the stop guide F are provided. As long as there is a gap between them, the plate-like body 3a does not stay in this position, and further slides sideways to one side of the roll conveyor A1 while being continuously conveyed in the direction indicated by the arrow a. Then, as illustrated in FIG. 12, when the tip of the plate-like body 3a comes into contact with the ruler roll 10, and one side surface of the plate-like body 3a comes into contact with the two guide rolls 13 and 13a, Since the plate-like body 3a is not further conveyed and the front end side is drawn out, the control of the control mechanism E1 is obtained and the driving of the roll conveyor A1 is stopped. At that time, in many normal cases, the vicinity of the tip of the plate-like body 3a does not buckle to a height higher than a predetermined limit, and a discrimination signal is not transmitted from the buckling discriminator D1, so that the ruler is accurately taken out. It turns out that

他方、何等かの原因によって、仮に図１３に例示する如く、板状体３ａの先端近傍が所定限度以上の高さに座屈したとすると、座屈判別器Ｄ１から判別信号が発信されるので、制御機構Ｅ１は、図１４に例示する如く、板状体３ａの先端が、ストッパＢ１の位置ＸからロールコンベアＡ１の搬送方向上手側へ所定距離Ｌ１隔てた、所定の隔離位置Ｙに至るまで、板状体３ａを一旦逆向きに搬送するように、ロールコンベアＡ１を逆転駆動させた後に、ロールコンベアＡ１を停止させ、次いで、図１５に例示する如く、板状体３ａを前記所定距離Ｌ１だけ搬送するに足る短期間だけ、再びロールコンベアＡ１を正転駆動させるように、駆動源９を介して、ロールコンベアＡ１の作動を制御するので、この場合も結果的に、定規出しが適確に行われる。   On the other hand, if the vicinity of the tip of the plate-like body 3a buckles to a height exceeding a predetermined limit as illustrated in FIG. 13 due to some cause, a discrimination signal is transmitted from the buckling discriminator D1. As shown in FIG. 14, the control mechanism E <b> 1 until the tip of the plate-like body 3 a reaches a predetermined isolation position Y that is a predetermined distance L <b> 1 away from the position X of the stopper B <b> 1 toward the upper side in the transport direction of the roll conveyor A <b> 1. The roll conveyor A1 is reversely driven so as to once transport the plate-like body 3a in the reverse direction, and then the roll conveyor A1 is stopped. Then, as illustrated in FIG. 15, the plate-like body 3a is moved to the predetermined distance L1. Since the operation of the roll conveyor A1 is controlled via the drive source 9 so that the roll conveyor A1 is driven to rotate in the normal direction again only for a short period of time, the ruler can be accurately detected as a result. Done to That.

尚、定規出しを終えた板状体は、図示しない適宜の手段を用いて、ロールコンベアの上方へ取出すと共に、所望の場所へ移動すれば差支えなく、或は図示は省略したが、必要に応じては、先記実施例に準じて、ストッパを構成する定規ロールを、ロールコンベアの搬送面に対して出没自在に備え、常態に於て、ロールコンベアの搬送面よりも上に突出させると共に、定規出しを終えた後で、ロールコンベアの搬送面よりも下に没入させ、ロールコンベアによる搬送を再開させることによって、当初の搬送方向と同方向に継続搬送するようにしても差支えない。   It should be noted that the plate-like body after the ruler has been taken out may be removed by using an appropriate means not shown above the roll conveyor and moved to a desired place, or the illustration is omitted. In accordance with the previous embodiment, the ruler roll constituting the stopper is provided so as to be able to appear and retract with respect to the transport surface of the roll conveyor, and in a normal state, protrudes above the transport surface of the roll conveyor, After finishing the ruler, it is possible to continue the conveyance in the same direction as the original conveyance direction by immersing below the conveyance surface of the roll conveyor and restarting the conveyance by the roll conveyor.

また更に別の実施例としては、例えば図１６に例示する如く、前記図９・図１０の実施例に於ける到達検出器Ｃ１に代えて、前記図９・図１０の実施例に於ける反射型光センサ１１に対して搬送方向の左右の対称的な位置に、同様の反射型光センサ１４を別途に追加配備して成る到達検出器Ｃ２を備えると共に、前記図９・図１０の実施例に於けるストップガイドＦに代えて、前記図９・図１０の実施例に於けるガイドロール１３・１３ａに対して搬送方向の左右の対称的な位置に、同様のガイドロール１５・１５ａを別途に追加配備して成るストップガイドＦ１を備える構成を採る装置が挙げられ、斯様な構成を採る装置によれば、実線及び点線で示す如く左右対称状に向きが異なる菱形の板状体３ａ・３ｂの定規出しを交互に行うことも可能であり、例えば「斜行型単板積層材の製造方法」（特許第３７２９４１０号公報）に開示される如き斜行型単板積層材の製造など、左右対称状に向きが異なる菱形の板状体を、交互に重ね合わせて積層する接着する場合などに適用するのに好都合である。   As still another embodiment, as shown in FIG. 16, for example, instead of the arrival detector C1 in the embodiment of FIGS. 9 and 10, the reflection in the embodiment of FIGS. 9 and 10 is provided with a arrival detector C2 additionally provided with a similar reflective optical sensor 14 at symmetrical positions on the left and right in the conveying direction with respect to the optical sensor 11. In place of the stop guide F in FIG. 9 and FIG. 10, similar guide rolls 15 and 15a are separately provided at symmetrical positions on the left and right in the conveying direction with respect to the guide rolls 13 and 13a in the embodiment of FIGS. And an apparatus having a stop guide F1 additionally provided, and according to the apparatus adopting such a configuration, the rhomboid plate-like body 3a, which has a symmetrical orientation as shown by a solid line and a dotted line, is provided. It is also possible to alternately perform the ruler 3b For example, the production of a skew type single plate laminate as disclosed in "Method for producing a skew type single plate laminate" (Japanese Patent No. 3729410) It is convenient to apply, for example, a case in which a state-of-the-art body is alternately laminated and laminated.

無論、前記各実施例に於ける定規ロール及びガイドロールの配設数については、図示した配設数に限るものではなく、必要に応じて、加増して差支えなく、更に、前記図１６の実施例に順ずる構成を採る場合については、必要に応じて、定規ロール及び／又はガイドロールを、左右各別に、搬送機構の搬送面に対して出没自在とする構成を採っても差支えない。   Of course, the number of ruler rolls and guide rolls in each of the above embodiments is not limited to the number shown in the drawings, and can be increased as necessary. In the case of adopting a configuration according to the example, if necessary, a ruler roll and / or a guide roll may be arranged so as to be able to appear and retract with respect to the conveyance surface of the conveyance mechanism separately on the left and right sides.

尚、定規部材の位置と所定の隔離位置との所定距離について言及すると、所定距離があまり過少（例えば数ｍｍ程度）である場合には、板状体の座屈が、当初の搬送姿勢と同様の状態にまで展ばされたか否か判然としない虞があるので、あまり過少なのは不適当であり、好ましくは１Ｃｍ以上（より好ましくは数Ｃｍ程度）とするのが実用的である。また、許容し得る座屈の高さについては、必要とする定規出しの精度、板状体の性状、定規部材の配設条件等に適応させるべく、実験に基づいて定めるのが実用的である。   In addition, referring to the predetermined distance between the position of the ruler member and the predetermined separation position, when the predetermined distance is too small (for example, about several mm), the buckling of the plate-like body is the same as the initial conveying posture. Since it is unclear whether or not it has been expanded to the above state, it is unsuitable to be too small, and it is practical to set it to 1 Cm or more (more preferably about several Cm). In addition, it is practical to determine the allowable buckling height based on experiments in order to adapt to the required accuracy of ruler feeding, the properties of the plate-like body, the arrangement conditions of the ruler members, and the like. .

以上明らかな如く、本発明によれば、搬送方向と同方向の強度が通例通り軟弱な板状体については、従前と同様に、格別支障なく安定的に定規出し処理を行うことができるのは勿論のこと、搬送方向と同方向の強度が通例よりも一段と軟弱な板状体が混在し、該通例よりも一段と軟弱な板状体の先端が座屈した場合であっても、適切に処置して適確な定規出し処理を行うことができるので、産業上の実用性は甚大であり、無論、必要に応じては、処理する全ての板状体が、通例よりも一段と軟弱であって、各枚毎に先端近傍が座屈する場合であっても、都度適切に処置して適確な定規出し処理を行うことができる。   As is apparent from the above, according to the present invention, it is possible to stably perform the ruler processing for a plate-like body whose strength in the same direction as the conveyance direction is normally weak, as before, without any particular trouble. Of course, even if a plate-like body whose strength in the same direction as the conveyance direction is softer than usual is mixed, and the tip of the plate-like body much weaker than usual is buckled, an appropriate treatment is performed. Therefore, it is possible to carry out accurate ruler processing, so industrial practicality is enormous.Of course, if necessary, all the plates to be processed are much softer than usual. Even when the vicinity of the tip is buckled for each sheet, it is possible to perform an appropriate measure each time and perform an accurate ruler process.
