Description

本発明は、ベニヤレースから送出される単板の処理方法に関するものである。   The present invention relates to a method for processing a single plate sent from a veneer race.

ベニヤレースによって原木を旋削すると、当初、不定形な原木の外周部からは、前後端部に不要部分を有する不定形な不連続状の単板が、次いで、原木が略円柱状となってからは、主として先端寄りの一部に不要部分を有する連続状（帯状）の単板が夫々送出されるので、次位の乾燥工程等に於ける省力化・効率化等を図る為に、前記各単板の不要部分を除去する処理（但し、後の乾燥収縮等に伴う歪の発生が予測されるので、不要部分は、必ずしも全て除去する必要はなく、一部を残して大半を除去する処理が通例である）と併せて、少なくとも連続状の単板を、所定の定尺寸法に定尺切断する処理が要求されることから、本出願人は以前、「単板の連続処理方法および装置」（特公昭５６−１３６０３号公報）に開示する如く、単板を連続的に切断して上下に分別する切断機構を前後に連結状に備えて成る単板の切断処理装置を用いて、前位の切断機構により、単板の不要部分の切除を、また後位の切断機構により、連続状の単板の定尺切断と、不連続状の単板同士の間隔を近接状に詰寄せて成る単板群の定尺切断とを行い、更に前記切断処理装置の後位に備えた堆積装置を用いて、定尺切断した単板及び単板群の堆積処理を行うようにした単板の処理方法を実用化し、合板工場に於て相応の成果を挙げるに至ったが、該処理方法は、二基の切断機構を備えた切断処理装置を用いるものであることから、当初の設備費の外に、切断機構を構成する部材の保守管理費・消耗費等が些か高額化する難点があった。   When a log is turned by veneer lace, an irregular discontinuous veneer with an unnecessary part at the front and rear ends is formed from the outer periphery of the irregular log, and then the log becomes substantially cylindrical. Since the continuous (strip-shaped) single plate mainly having an unnecessary part near the tip is sent out, in order to save labor and improve efficiency in the subsequent drying process, etc. Processing to remove the unnecessary part of the veneer (however, it is predicted that distortion will occur due to subsequent drying shrinkage, etc., so it is not always necessary to remove all of the unnecessary part. In addition, the present applicant has previously stated that “a method and an apparatus for continuous processing of a single plate”, since a process of cutting at least a continuous single plate into a predetermined size is required. As disclosed in Japanese Patent Publication No. 56-13603. Using a single-plate cutting processing device that has a cutting mechanism that cuts and separates up and down in a connected manner in the front and rear, using the front cutting mechanism to cut off unnecessary parts of the single plate, The cutting mechanism performs a constant cutting of continuous single plates and a single cutting of a single plate group formed by closely closing the intervals between discontinuous single plates, and further after the cutting processing device. Using the deposition equipment prepared for the first place, we put into practical use a processing method for single plate that was designed to perform the processing of single-cut single plates and single plate groups and led to corresponding results at the plywood factory. However, since this processing method uses a cutting processing apparatus equipped with two cutting mechanisms, in addition to the initial equipment costs, the maintenance management costs and consumption costs of the members constituting the cutting mechanisms are insignificant. However, there was a difficulty in increasing the price.

そこで、本出願人は改めて、「単板の処理方法及び単板の処理装置」（特開２００２−２９２６０６号公報）に開示する如く、ベニヤレースの後位へ、単板を連続的に切断して上下に分別する切断装置を備えると共に、該切断装置の後位へ上下二段から成る有効単板の通路と開閉自在な屑の排出路とを、下段の通路が屑の排出路の後位に位置すべく設け、ベニヤレースから送出される単板を前記切断装置によって順次と切断処理するに際し、定尺切断すべき単板が到来するまでは、屑の排出路を常に開放して、単板の不要部分を（好ましくは、先記通例通り、一部を残して大半を）屑として切除する処理を行い、また定尺切断すべき単板が到来した後は、屑の排出路を閉塞して、後続する単板に不要部分が存在するか否かに拘わらず、定尺切断のみを行うようにした単板の処理方法を提案して、当初の設備費や、切断装置を構成する部材の保守管理費・消耗費等の低減化を図った。
特開２００２−２９２６０６号公報 Therefore, the applicant again cuts the single plate continuously to the rear of the veneer race as disclosed in “Single plate processing method and single plate processing apparatus” (Japanese Patent Laid-Open No. 2002-292606). And a cutting device for separating the upper and lower parts, and an effective veneer passage having two upper and lower stages and an openable and closable waste discharge path to the rear of the cutting apparatus, and a lower passage is located behind the waste discharge path. When the single plate sent from the veneer lace is sequentially cut by the cutting device, the waste discharge path is always opened until the single plate to be cut in a constant size arrives. Unnecessary parts of the board are cut off as waste (preferably, as in the previous case, most of the parts are left), and after the veneer to be cut in length comes, the waste discharge path is blocked. Regardless of whether there is an unnecessary part in the following veneer Proposes a method of processing a single plate so as to perform only, and the initial equipment costs, it tried to reduce the maintenance costs and consumables expenses of members constituting the cutting device.
JP 2002-292606 A

前記文献の提案は、提案の主題である各種の費用の低減化には有効なものであったが、ベニヤレースの後方に於ける単板処理工程全体の省力化・効率化等を図る為には、単板の切断処理の外に、切断処理した単板の後処理も重要な課題であり、而も該課題の解決を図るに際しては、例えば切断処理した単板は、堆積装置を用いて自動的に堆積処理するか、或は所望の定尺寸法の接合単板に形成して堆積処理するのが好ましく、また次工程に於ける再処理の利便性からすると、堆積処理するに際しては、所定の定尺寸法を以って定尺切断した単板（以下、単に定尺単板と称す）と定尺単板以外の乱尺の単板（以下、単に乱尺単板と称す）とを可及的に弁別して堆積処理するのが好ましく、更にそれら切断処理と、堆積処理又は／及び接合堆積処理等とを、一連の連結処理ラインとして実施するに際しては、可及的に狭小のスペースに収めるのが好ましい等々、種々の好ましい条件を充足することが望まれる。   The proposal in the above literature was effective in reducing various costs that are the subject of the proposal, but in order to save labor and improve the efficiency of the entire veneer processing process behind the veneer race. In addition to the cutting process of the single plate, post-processing of the cut single plate is also an important issue. In order to solve the problem, for example, the single plate that has been cut is processed by using a deposition apparatus. It is preferable to perform the deposition process automatically or to form and form a bonded single plate of a desired standard size, and from the convenience of reprocessing in the next step, A single plate (hereinafter simply referred to as a “single-sized single plate”) that has been cut to a predetermined size and a single-layer plate other than a single-sized single plate (hereinafter simply referred to as a “random-sized single plate”) It is preferable to discriminate as much as possible and perform the deposition process, and further, the cutting process, the deposition process and / or the bonding deposition process. And etc., when implemented as a series of linked processes lines, etc. preferably fit in the space narrow as possible, it is desirable to satisfy the various preferred conditions.

そこで更に、本出願人は、ベニヤレースの後方に於ける単板処理工程全体の省力化・効率化等を図るべく、前記文献の提案を基に、一連の連結処理ラインの開発を進め、ベニヤレースの後位へ、単板を連続的に切断して上下に分別する切断装置を備えると共に、該切断装置の後位へ上下二段から成る有効単板の通路と開閉自在な屑の排出路とを、屑の排出路が下段の通路の前位に位置すべく設け、而も上下二段の内の上段の通路を、単板通行方向下手側に於て下段の通路に合流させ、且つ、上段の通路に拘わる条件の内で、通路の稼動時間又は通路の通行速度又は通路の長さの内の少なくともいずれか一つの条件を、上段の通路を通過する単板の前端が、両通路の合流位置に於て、下段の通路を通過する単板の前端と丁度重なり合うように設定し、更に下段の通路の後位に、定尺単板を堆積する定尺単板堆積装置と、乱尺単板を単に堆積する乱尺単板堆積装置又は乱尺単板を所望の定尺寸法の接合単板に形成して堆積する単板接合堆積装置の少なくともいずれか一つの装置とを備え、ベニヤレースから送出される単板を前記切断装置によって切断処理するに際し、定尺切断すべき単板が到来するまでは、屑の排出路を常に開放して、単板の不要部分の大半を屑として切除すると共に、上段の通路に流入した有効単板（乱尺単板）を、下段の通路を介して、乱尺単板堆積装置及び／又は単板接合堆積装置に移送し、単に堆積及び／又は接合単板に形成して堆積する処理を行い、また定尺切断すべき単板が到来した後は、屑の排出路を閉塞して、後続する単板に不要部分が存在するか否かに拘わらず、定尺切断のみを行って、定尺単板を上下二段の有効単板の通路へ交互に配送すると共に、両通路の合流位置に於て二重状に重ね合わせてから定尺単板堆積装置に移送し、順次堆積する処理を行う単板の処理方法を、有効な処理方法として提案する前段階に至った。   Therefore, in order to save labor and improve the efficiency of the entire veneer processing process behind the veneer race, the present applicant has proceeded with the development of a series of connection processing lines based on the proposal of the above-mentioned literature. A cutting device that continuously cuts the single plate to the rear of the race and separates it up and down is provided. The rear of the cutting device has a two-stage effective single plate passage and an openable / closable waste discharge passage. , So that the waste discharge path is positioned in front of the lower passage, the upper passage in the upper and lower two stages is joined to the lower passage on the lower side in the single plate passage direction, and Among the conditions related to the upper passage, at least one of the operation time of the passage, the passage speed of the passage, or the length of the passage, the front end of the single plate passing through the upper passage has both passages. At the merging position, so that it overlaps the front edge of the veneer that passes through the lower passage. Furthermore, at the rear of the lower passage, a fixed-size veneer depositing device for depositing a fixed-size veneer, and a random-sized veneer stacking device for simply depositing an irregular veneer, At least one of the single-plate joining and depositing devices that are formed and deposited on the joining single plates of the method, and when the single plate sent from the veneer lace is cut by the cutting device, it should be cut at a fixed length Until the veneer arrives, the waste discharge path is always opened, and most of the unnecessary portion of the veneer is cut off as waste, and the effective veneer that flows into the upper passage (random scale veneer) A single plate to be transferred to a random-scale single plate deposition apparatus and / or single-plate bonding deposition apparatus through the path of the plate, and simply deposited and / or formed and deposited on a single plate and deposited. After arriving, the waste discharge path is blocked and whether there is an unnecessary part on the subsequent veneer Regardless of the method, only standard cutting is performed, and the standard single plates are delivered alternately to the upper and lower two-stage effective single plate passages and overlapped at the merging position of both passages. A single plate processing method for transferring to a single veneer depositing apparatus and sequentially depositing it has reached a stage before proposing it as an effective processing method.

前記開発した処理方法の要点は、後に詳解する図１〜図４に例示する如く、切断装置Ａの後位へ、定尺単板２Ｂを堆積する定尺単板堆積装置Ｃと、乱尺単板２Ａを堆積する乱尺単板堆積装置Ｅ及び／又は乱尺単板２Ａを接合単板２Ｃに形成して堆積する単板接合堆積装置Ｇを個別に備えて、定尺単板２Ｂを乱尺単板２Ａとは弁別して堆積処理するに際し、切断装置Ａの後位に設けた上段の通路ａに拘わる条件の内で、通路の稼動時間又は通路の通行速度又は通路の長さの内の少なくともいずれか一つの条件を、適切に調整（設定）して、切断装置Ａの直後に於て一旦上下二段の通路ａ・ｂへ交互に配送した二枚の定尺単板２Ｂを、両通路ａ・ｂの合流位置に於て二重状に重ね合わせてから定尺単板堆積装置Ｃに移送して堆積する構成を採ることにより（図５参照）、定尺単板堆積装置Ｃに於ける必要十分な堆積処理時間の確保を可能として、堆積処理の安定化を図ると共に、定尺単板堆積装置Ｃの所要基数の最少化を可能として、所要スペースの狭小化を図ったものであり、先記好ましい諸条件を概ね充足するものであったが、開発過程に於て、下記の弱点があることが判明した。 The main point of the developed processing method is that, as illustrated in FIGS. 1 to 4 which will be described in detail later, a fixed single plate deposition apparatus C for depositing a fixed single plate 2B to the rear of the cutting apparatus A, comprises a veneer bonding deposition apparatus G depositing a turbulent scale veneer deposition apparatus E and / or turbulence scale veneer 2A depositing plate 2A formed in bonded veneers 2C separately, turbulent a fixed size veneer 2B When the stacking process is performed by discriminating from the single plate 2A , within the operating time of the passage, the passage speed of the passage, or the length of the passage within the conditions relating to the upper passage a provided at the rear of the cutting device A. At least one condition is appropriately adjusted (set), and immediately after the cutting device A, the two single-sized single plates 2B once alternately delivered to the upper and lower two-stage passages a and b are A structure is adopted in which the layers are overlapped at the merging position of the passages a and b, and then transferred to the single plate deposition apparatus C to be deposited. (See FIG. 5), it is possible to secure a necessary and sufficient deposition processing time in the fixed-size single plate deposition apparatus C, to stabilize the deposition process, and to minimize the required number of the fixed-size single plate deposition apparatus C. The required space was narrowed and the above-mentioned preferable conditions were generally satisfied, but it was found that the following weak points were found in the development process.

即ち、定尺切断すべき単板が到来した後は、屑の排出路を閉塞して、後続する単板に不要部分が存在するか否かに拘わらず、定尺切断のみを行った際に、該定尺切断が偶数回で終了し、偶数枚の定尺単板が得られた場合については、上下二段の通路ａ・ｂの稼動態様を通常通りに維持しても、図６に例示する如く、定尺切断が終了した後に送出される残余の乱尺単板２Ａが、上段の通路ａを介して下段の通路ｂに流入する際には、下段の通路ｂに他の単板が存在しないので（先行する二重状の定尺単板２Ｂとの間には、定尺単板２Ｂの定尺寸法Ｗと同等の間隔が生じている）、特に問題が発生する虞はない。   In other words, after a single plate to be cut in regular size has arrived, the waste discharging path is closed, and only the fixed cut is performed regardless of whether or not there is an unnecessary part in the subsequent single plate. In the case where the regular cutting is finished in an even number of times and an even number of the standard single plates are obtained, even if the operation mode of the upper and lower two-stage passages a and b is maintained as usual, As illustrated, when the remaining irregular single plate 2A delivered after the regular cutting is finished flows into the lower passage b through the upper passage a, the other single plate enters the lower passage b. Since there is no gap (the same distance as the standard dimension W of the standard single plate 2B is generated between the preceding double standard single plate 2B), there is no possibility that a problem will occur. .

ところが、定尺切断が奇数回行われて終了し、奇数枚の定尺単板が得られた場合については、図７に例示する如く、下段の通路ｂを進行する残余の乱尺単板２Ａが、上下二段の通路ａ・ｂの合流位置に到達した際に、上段の通路ａを介して下段の通路ｂに奇数枚目の定尺単板２Ｂが流入し、残余の乱尺単板２Ａの上に奇数枚目の定尺単板２Ｂが重なる状態となり、この状態のまま定尺単板堆積装置Ｃに移送されて堆積されることとなるので、好ましくは定尺単板のみで形成すべき定尺単板の堆積山に乱尺単板が混入する事態が生じて、例えば定尺単板の堆積山の堆積姿勢が悪化したり、或は例えば後処理工程に於ける定尺単板の堆積山の取扱い性を劣化させるなどの不都合が惹起される。   However, in the case where odd-numbered single-size sheets are obtained after the odd-number cutting has been performed an odd number of times, as shown in FIG. 7, the remaining irregular single-sheet 2A traveling in the lower passage b is illustrated. However, when reaching the joining position of the upper and lower two-stage passages a and b, the odd-numbered single plate 2B flows into the lower passage b through the upper passage a, and the remaining irregular single plates Since the odd-numbered single plate 2B overlaps 2A and is transferred to and deposited in the single-plate stacking device C in this state, it is preferably formed only by the single plate. For example, when a random single plate is mixed into a pile of fixed-size single plates to be deposited, for example, the deposition posture of the pile of fixed-size single plates is deteriorated, or, for example, a single-unit single plate in a post-processing process is deteriorated. Inconveniences such as deterioration of the handleability of the piles of the plate are caused.

本発明は、前記開発した処理方法の弱点を解消すべく、更に改良を加えて新たに開発したものであり、該開発した処理方法の構成を前提として、定尺切断が偶数回行われて終了した場合には、各通路の稼動態様を通常通りに維持することにより、上段の通路に流入した残余の乱尺単板を、定尺単板と同様の時期に、単独で下段の通路に流入させて、乱尺単板堆積装置及び／又は単板接合堆積装置に移送する処理を、また定尺切断が奇数回行われて終了した場合に限っては、例外的に、上段の通路の稼動を暫時遅延させてから通常通りに復帰させる態様に変更することにより、下段の通路に流入した残余の乱尺単板を、優先的に単独で乱尺単板堆積装置及び／又は単板接合堆積装置に移送し、上段の通路で暫時待機させていた定尺単板を、後から単独で下段の通路に流入させて、定尺単板堆積装置に移送する処理を行うことを特徴とする単板の処理方法（請求項１）を、新たに提案する。   The present invention has been newly developed with further improvements in order to eliminate the weaknesses of the developed processing method, and on the premise of the configuration of the developed processing method, regular cutting is performed an even number of times and finished. In such a case, by maintaining the operating mode of each passage as usual, the remaining irregular veneer flowing into the upper passage flows into the lower passage independently at the same time as the fixed veneer. The upper passage is operated only when the process of transferring to the irregular single plate deposition apparatus and / or single plate bonding deposition apparatus is completed, and only when the regular cutting is finished an odd number of times. By changing to a mode in which it is delayed for a while and then returned to normal, the remaining turbulent veneer that has flowed into the lower passage is preferentially singly undetermined single veneer and / or veneer bonded deposit After transferring the standard veneer that was transferred to the machine and kept waiting for a while in the upper passage, Alone and allowed to flow into the lower passage, the processing method of the veneer, which comprises carrying out the process of transferring the standard length veneer deposition apparatus (claim 1), we propose.

また、前記提案の更なる改良例として、定尺単板堆積装置を介して乱尺単板が乱尺単板堆積装置に移送されるよう、乱尺単板堆積装置を、定尺単板堆積装置の後位へ連結状に備えると共に、別途に単板接合堆積装置を、乱尺単板堆積装置の後位へ分離状に備え、更に上下二段の有効単板の通路に於ける下段の通路と単板接合堆積装置とを連結する機構として、両通路の合流位置と定尺単板堆積装置との間に於ける下段の通路に対して出没する方向に可動自在な分岐移送機構を単板移送方向上手側に備えて成る連結移送機構を、定尺単板堆積装置及び乱尺単板堆積装置を迂回させて単板接合堆積装置の前位へ備え、適時、前記連結移送機構の分岐移送機構を下段の通路に対して出没させることによって、乱尺単板堆積装置による乱尺単板の堆積処理と、単板接合堆積装置による接合単板の形成・堆積処理とを適時選択的に行って成る請求項１記載の単板の処理方法（請求項２）と、定尺単板堆積装置の後位に少なくとも単板接合堆積装置を設け、定尺切断すべき単板の末尾に近い部分に於て、最後の定尺切断を行う際に、該最後の定尺切断が、奇数回目の定尺切断に相当し、而も定尺切断を行ったと仮定すると、残余の単板の幅が、規定の最少限度幅以下となる場合に限っては、特例として、最後の定尺切断を中止すると共に、定尺単板よりも幅の広い乱尺単板を、連結移送機構を介して単板接合堆積装置に移送する処理を行って成る請求項１又は請求項２記載の単板の処理方法（請求項３）とを提案する。   Further, as a further improved example of the above proposal, the irregular single plate deposition apparatus is fixed to the regular single plate deposition so that the irregular single plate is transferred to the random single plate deposition apparatus via the regular single plate deposition apparatus. In addition to connecting to the rear of the device, a separate single plate bonding deposition device is separately provided to the rear of the random single plate deposition device, and the lower stage in the upper and lower two-stage effective single plate passages. As a mechanism for connecting the passage and the single plate bonding deposition apparatus, a single branch transfer mechanism that is movable in the direction of projecting and retracting with respect to the lower passage between the joining position of both passages and the fixed single plate deposition apparatus is used. The connection transfer mechanism provided on the upper side in the plate transfer direction is bypassed the fixed-size single plate deposition apparatus and the irregular single-plate deposition apparatus and is provided in front of the single-plate bonding deposition apparatus. Accumulation of irregular plates by means of an irregular plate deposition device by letting the transport mechanism in and out of the lower passage. The method for processing a single plate according to claim 1 (Claim 2), and the method for forming and depositing a bonded single plate by a single plate bonding and depositing apparatus in a timely and selective manner. At least a single plate bonding deposition device is provided in the rear, and when performing the final cut at a portion close to the end of the single plate to be cut, the final cut is an odd number of times. Assuming that it is equivalent to a scale cut and that a standard cut was made, the last cut will be canceled as a special case only if the width of the remaining veneer is less than the specified minimum width. The processing method of the single plate of Claim 1 or Claim 2 which performs the process which transfers the disordered single plate wider than a fixed-size single plate to a single plate joining deposition apparatus via a connection transfer mechanism. (Claim 3) is proposed.

前記請求項１に係る構成の単板の処理方法によれば、たとえ定尺切断が偶数回又は奇数回のいずれの回数行われても、定尺切断が終了した後に送出される残余の乱尺単板が、定尺単板の堆積山には決して混入しないので、定尺単板の堆積山の堆積姿勢が悪化したり、後処理工程に於ける定尺単板の堆積山の取扱い性を劣化させるなどの不具合が惹起される虞がない。   According to the method for processing a single plate having the configuration according to claim 1, even if the regular cutting is performed even number or odd number of times, the remaining irregularity sent after the regular cutting is finished. Since the veneer never gets mixed with the piles of the standard veneer, the stacking posture of the piles of the standard veneer deteriorates and the handling of the piles of the standard veneer in the post-processing process is improved. There is no risk of causing problems such as deterioration.

また、請求項２に係る構成の単板の処理方法によれば、連結移送機構の分岐移送機構による分岐動作により、乱尺単板を対象として、単なる堆積処理と接合単板の形成・堆積処理とが、所望時に適宜選択的に実施できるので至便であって、例えば単板接合堆積装置の接合材の補充時、或は例えば接合単板の堆積山の取出し時などに、単板接合堆積装置の稼動を暫時停止させても、乱尺単板堆積装置による乱尺単板の堆積を実施すれば、一連の連結処理ラインを休止させる必要はなく、逆に乱尺単板の堆積山の取出し時に、単板接合堆積装置による接合単板の形成・堆積処理を優先させても差支えない。更に、必要に応じては、非常時の対処として、定尺単板を乱尺単板堆積装置に於て堆積処理するように変更することも可能である。   In addition, according to the processing method of the single plate having the configuration according to claim 2, simple deposition processing and formation / deposition processing of the bonded single plate are performed on the irregular single plate by the branching operation by the branch transfer mechanism of the connection transfer mechanism. It is convenient because it can be carried out selectively when desired. For example, when replenishing the bonding material of the single plate bonding deposition apparatus or when taking out the piles of the bonding single plate, for example, the single plate bonding deposition apparatus Even if the operation of the unit is stopped for a while, it is not necessary to stop a series of connected processing lines if the accumulation of irregular single plates using the irregular single plate deposition device is performed. Sometimes, priority may be given to the process of forming and depositing bonded single plates by a single plate bonding deposition apparatus. Furthermore, if necessary, as a countermeasure in an emergency, it is possible to change the fixed-size single plate to be deposited in a random-size single plate deposition apparatus.

また更に、定尺切断が終了した後に送出される残余の乱尺単板の幅が、著しく狭いと、例えば筒状に丸まり易いので円滑に後工程へ流れなかったり、或は例えば単板繊維の方向に沿って割れ易いので利用が不能化したり、更には例えば乾燥後の再成形（不要部分の除去・他の単板との接合など）時に、利用可能な最少幅を得ることが困難化したりするなどの諸問題が惹起される虞があるが、請求項３に係る構成の単板の処理方法によれば、斯かる諸問題が惹起される虞がなく、総じて単板歩留りが向上する。   Furthermore, if the width of the remaining irregular single plate sent out after the regular cutting is extremely narrow, for example, it tends to be rounded into a cylindrical shape so that it does not flow smoothly to the subsequent process, or for example, the single plate fiber Since it is easy to break along the direction, it becomes impossible to use it, or it becomes difficult to obtain the minimum width that can be used, for example, when re-forming after drying (removing unnecessary parts, joining with other single plates, etc.) However, according to the veneer processing method having the configuration according to claim 3, there is no possibility that such problems are caused, and the veneer yield is generally improved.

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、一連の処理ラインを連結するベニヤレースの形式については、特に制約がなく、如何様な形式のベニヤレースであっても差支えないので、便宜上、図示を省略する。また、一連の処理ラインを構成する装置類・機構類につても、本発明独特の制御を行う制御機構を除いては、従来公知の装置類・機構類をそのまま活用・転用して差支えないので、便宜上、図示及び説明を簡略化する。   Hereinafter, the present invention will be described in further detail with an example of the embodiment illustrated in the drawings. However, the type of veneer lace connecting a series of processing lines is not particularly limited, and any type of veneer lace may be used. The illustration is omitted for convenience. In addition, with respect to the devices and mechanisms constituting a series of processing lines, except for a control mechanism that performs control peculiar to the present invention, there is no problem with utilizing and diverting conventionally known devices and mechanisms as they are. For convenience, illustration and description are simplified.

It is a partial side surface schematic explanatory drawing of the latter half part of the apparatuses and mechanisms which comprise a series of processing lines used for implementation of the processing method of a board. In the figure, reference numeral 1 denotes a transfer conveyor, which transfers a single plate 2 cut from a veneer lace (not shown) at the same speed as the single plate turning speed of the veneer lace in the direction of the arrow.

Ａは、先記文献等に開示した公知の切断装置であって、前記移送コンベア１の後部上方に配設され、単板２の不要部分を検知して、後述する制御機構Ｂへ検知信号を発信する単板検知機構３、移送コンベア１と同速度で図示矢印方向へ連続的に回転する上下一対の刃受体兼用の搬送ロール４・５、実線及び点線で示す如く、単板２の進行方向と逆方向に向けた刃先６ａが、前記一対の搬送ロール４・５の出口側周面に交互に接するように、図示矢印方向へ交互に片道回動する切断刃６等を具備し、前記単板検知機構３の検知信号に基づく制御機構Ｂの制御を得て、適時、切断刃６を交互に片道回動させることにより、単板２の不要部分２ａの大半を切除して乱尺単板２Ａを形成すると共に、後述する単板検出器１０及び定尺検出器１１・１２の検出信号に基づく制御機構Ｂの制御を得て、適時、切断刃６を交互に片道回動させることにより、単板２を所定の定尺寸法Ｗ毎に定尺切断して定尺単板２Ｂを形成する（図５参照）。   A is a known cutting device disclosed in the above-mentioned literature, etc., which is disposed above the rear portion of the transfer conveyor 1, detects an unnecessary portion of the veneer 2, and sends a detection signal to the control mechanism B described later. Single plate detection mechanism 3 for transmitting, a pair of upper and lower blade receiving and conveying rolls 4 and 5 that rotate continuously in the direction of the arrow at the same speed as the transfer conveyor 1, and the progress of the single plate 2 as indicated by the solid and dotted lines The cutting edge 6a or the like directed in the direction opposite to the direction is provided with cutting blades 6 or the like that alternately rotate in one direction in the direction of the arrow so that the cutting edge 6a directed in the direction opposite to the direction alternately contacts the outlet side peripheral surface of the pair of transport rolls 4 and 5; By obtaining control of the control mechanism B based on the detection signal of the single plate detection mechanism 3 and rotating the cutting blades 6 alternately one way at a time, most of the unnecessary portions 2a of the single plate 2 are cut off to obtain a random unit. The plate 2A is formed and the single plate detector 10 and the fixed detectors 11 and 12 described later are formed. By obtaining the control of the control mechanism B based on the detection signal and rotating the cutting blades 6 alternately one way at a time, the single plate 2 is cut in a predetermined length W every predetermined size W 2B (See FIG. 5).

７は、下段の有効単板の通路ｂと屑の排出路ｃとを構成する下段コンベアであって、屑の排出路ｃが下段の通路ｂの前位に位置すべく、前記一対の搬送ロール４・５の後位に備えられており、後述する制御機構Ｂの制御を得て、常に該一対の搬送ロール４・５と同速度で図示矢印方向へ走行し、定尺単板２Ｂと、定尺切断が終了した後に送出される残余の乱尺単板２Ａとを、後述する定尺単板堆積装置Ｃと乱尺単板堆積装置Ｅへ移送する。   7 is a lower-stage conveyor that constitutes a lower-stage effective veneer passage b and a waste discharge path c, and the pair of transport rolls so that the waste discharge path c is positioned in front of the lower-stage passage b. 4 and 5 are provided at the rear, and obtain the control of the control mechanism B, which will be described later, and always travel in the direction of the arrow shown in the figure at the same speed as the pair of transport rolls 4 and 5; The remaining random single plate 2A that is sent out after the completion of the regular cutting is transferred to a single plate deposition apparatus C and a random single plate deposition apparatus E, which will be described later.

８は、上段の有効単板の通路ａを構成する上段コンベアであって、該上段の通路ａが、単板通行方向下手側に於て、下段の通路ｂに合流するように、前記下段コンベア７の上方に備えられており、通常は、後述する制御機構Ｂの制御を得て、前記一対の搬送ロール４・５と同速度で図示矢印方向へ連続的に走行し、原木の旋削初期に前記切断装置Ａから送出される乱尺単板２Ａを下段の通路ｂへ流入させるのみならず、定尺切断が行われた以降に於ては、原則的に、定尺単板２Ｂが完全に上段のコンベア７上に移乗される状態となる都度、所定期間だけ稼動を休止してから、稼動を再開する稼動形態が採られ、上段の通路ａを進行する定尺単板２Ｂが、下段の通路ｂを進行する定尺単板２Ｂの上に重なり合うように合流させる（図５参照）。そして、次の原木の旋削が新たに開始されるまでは、都度所定期間だけ稼動を休止する通常の稼動形態が維持されるので、定尺切断が偶数回行われて終了した場合には、定尺切断が終了した後に送出される残余の乱尺単板２Ａも、定尺単板２Ｂと同様に暫時待機させてから下段の通路ｂへ流入させる（図６参照）。一方、定尺切断が奇数回行われて終了した場合に限っては、制御機構Ｂの制御を得て、通常の所定期間よりも長い期間、例えば通常の所定期間の二倍を越える期間稼動を休止してから、稼動を再開する例外的な稼動形態が採られ、上段の通路ａを進行する定尺単板２Ｂが、下段の通路ｂを進行する残余の乱尺単板２Ａと重なり合わないようにする（図８参照）。   8 is an upper conveyor constituting the upper-stage effective veneer passage a, and the upper-stage passage a is joined to the lower-stage passage b on the lower side of the single-plate passage direction. 7, usually under the control of the control mechanism B, which will be described later, continuously running in the direction of the arrow shown in the figure at the same speed as the pair of transport rolls 4 and 5, and at the initial turning of the raw wood Not only does the irregular single plate 2A delivered from the cutting device A flow into the lower passage b, but also after the standard cutting is performed, in principle the single plate 2B is completely Each time it is transferred to the upper conveyor 7, an operation mode is adopted in which the operation is stopped for a predetermined period and then the operation is resumed. It joins so that it may overlap on the fixed length single board 2B which advances the channel | path b (refer FIG. 5). Then, until the next raw wood turning is newly started, the normal operation mode in which the operation is suspended for a predetermined period of time is maintained. The remaining disordered single plate 2A that is sent out after the end of the cutting is also made to wait for a while like the fixed single plate 2B and then flow into the lower passage b (see FIG. 6). On the other hand, only when the regular cutting is finished an odd number of times, the control mechanism B is controlled to operate for a period longer than the normal predetermined period, for example, more than twice the normal predetermined period. An exceptional operation mode is adopted in which the operation is resumed after the operation is stopped, and the fixed-size veneer 2B traveling in the upper passage a does not overlap the remaining irregular veneer 2A traveling in the lower passage b. (See FIG. 8).

９は、屑の排出路の開閉部材であって、実線及び点線で示す如く、先端側が下搬送ロール４と上段コンベア８とに交互に接近するように、図示矢印方向へ交互に片道回動自在に備えられており、後述する制御機構Ｂの制御を得て、適時、屑の排出路ｃを開閉する。   9 is an opening / closing member for the waste discharge path, and as indicated by the solid and dotted lines, it can be rotated one-way alternately in the direction of the arrow so that the tip side alternately approaches the lower transport roll 4 and the upper conveyor 8. In order to open and close the waste discharge path c in a timely manner under the control of the control mechanism B described later.

１０は、切断装置Ａの前位に於ける移送コンベア１の上方等に備えた単板検出器であって、移送コンベア１によって移送される単板２の有無を検出し、後述する制御機構Ｂに検出信号を発する。因に、当該単板検出器から発信される検出信号が、所定時間以上継続されれば、定尺切断すべき単板が到来したことが、更に、その後に検出信号が一定時間以上途絶えれば、単板の末尾が到来したことが、制御機構によって夫々判別できる。   Reference numeral 10 denotes a single plate detector provided above the transfer conveyor 1 at the front of the cutting device A, and detects the presence or absence of the single plate 2 transferred by the transfer conveyor 1, and a control mechanism B described later. A detection signal is issued. In addition, if the detection signal transmitted from the single plate detector is continued for a predetermined time or longer, it is confirmed that a single plate to be cut in a fixed length has arrived, and then if the detection signal is interrupted for a predetermined time or longer. The control mechanism can determine that the end of the veneer has arrived.

１１・１２は、上下二段の有効単板の通路ａ・ｂの所定位置に備えた定尺検出器であって、不要部分２ａを切除された単板２、或は定尺切断に伴って配送された単板２等の先端が所定位置に至る都度、後述する制御機構Ｂに検出信号を発する。   Reference numerals 11 and 12 are standard detectors provided at predetermined positions in the passages a and b of the upper and lower two-stage effective single plates. The single plate 2 from which unnecessary portions 2a are cut off, or along with the standard cutting. Each time the tip of the delivered single plate 2 or the like reaches a predetermined position, a detection signal is issued to the control mechanism B described later.

Ｂは、前記切断装置Ａ、上下二段のコンベア７・８、開閉部材９等の作動を制御する制御機構であって、以下に詳述する如き制御形態を実施する。即ち、ベニヤレースから削成される単板２の切断処理を開始する際には、都度、切断装置Ａの切断刃６を点線で示した待機位置に、また開閉部材９を実線で示した待機位置に夫々待機させると共に、上下二段のコンベア７・８を切断装置Ａの搬送ロール４・５と同速度で図示矢印方向へ走行させるよう制御する。次いで、移送コンベア１を介して切断装置Ａに単板２が移送され、単板検知機構３から検知信号が発信されると、単板２の有効部分と前端側の不要部分２ａの境界が、切断刃６の刃先６ａの位置に到達する直前に切断刃６を実線で示す位置へ片道回動させるよう制御することにより、前端側の不要部分２ａの大半を切除して屑の排出路ｃへ排出すると共に、単板２の有効部分を上段の通路ａへ流入させる。更に、単板２の後端の通過に伴って、単板検知機構３から検知信号が発信されると、単板２の有効部分と後端側の不要部分２ａの境界が、切断刃６の刃先６ａの位置を通過した直後に切断刃６を点線で示す位置へ片道回動させるよう制御することにより、後端側の不要部分２ａの大半を切除して屑の排出路ｃへ排出すると共に、乱尺単板２Ａは、引続き上段の通路ａを進行させ、そのまま下段の通路ｂへ流入させる。以下、定尺切断すべき単板が到来するまでは、同様の動作の繰返しにより、順次と単板２の不要部分２ａの大半を切除して、屑の排出路ｃへ排出し、乱尺単板２Ａを形成する。   B is a control mechanism for controlling the operation of the cutting device A, the upper and lower conveyors 7 and 8, the opening and closing member 9, etc., and implements a control mode as described in detail below. That is, each time the cutting process of the veneer 2 cut from the veneer lace is started, the cutting blade 6 of the cutting apparatus A is in the standby position indicated by the dotted line, and the standby member 9 is indicated by the solid line. Control is performed such that the upper and lower conveyors 7 and 8 run in the direction indicated by the arrows at the same speed as the conveying rolls 4 and 5 of the cutting device A, while waiting at the respective positions. Next, when the veneer 2 is transferred to the cutting device A via the transfer conveyor 1 and a detection signal is transmitted from the veneer detection mechanism 3, the boundary between the effective portion of the veneer 2 and the unnecessary portion 2a on the front end side is Just before reaching the position of the cutting edge 6a of the cutting blade 6, the cutting blade 6 is controlled so as to be rotated one way to the position indicated by the solid line, so that most of the unnecessary portion 2a on the front end side is cut off to the waste discharge path c. While discharging, the effective part of the veneer 2 is caused to flow into the upper passage a. Furthermore, when a detection signal is transmitted from the single plate detection mechanism 3 as the rear end of the single plate 2 passes, the boundary between the effective portion of the single plate 2 and the unnecessary portion 2a on the rear end side of the cutting blade 6 Immediately after passing through the position of the blade edge 6a, the cutting blade 6 is controlled to rotate one way to the position indicated by the dotted line, so that most of the unnecessary portion 2a on the rear end side is cut out and discharged to the waste discharge path c. Then, the irregular single plate 2A continues to advance in the upper passage a and flows into the lower passage b as it is. Thereafter, until a single plate to be cut is reached, by repeating the same operation, most of the unnecessary portions 2a of the single plate 2 are sequentially cut out and discharged to the waste discharge path c. A plate 2A is formed.

やがて、定尺切断すべき単板２が到来するのに伴って、単板検出器１０による検出信号が、所定時間以上継続されて発信され、而も前端側の不要部分２ａの大半を切除された単板２の前端が、定尺検出器１１の位置に到達して、該定尺検出器１１から検出信号が発信されると、実線で示す位置に待機していた開閉部材９を点線で示す位置に片道回動させ、屑の排出路ｃを閉塞すると共に、実線で示す位置にあった切断刃６を点線で示す位置へ片道回動させるよう制御することにより、単板２を所定の定尺寸法Ｗ（図１０参照）を以って定尺切断し、後続する単板２を下段の通路２ｂへ流入させる。次に、下段の通路２ｂに流入した単板２の前端が、定尺検出器１２の位置に到達し、該定尺検出器１２から検出信号が発信されると、点線で示す位置にある切断刃６を実線で示す位置へ片道回動させるよう制御することにより、再び単板２を所定の定尺寸法Ｗを以って定尺切断する。以下、単板２の末尾が到来するのに伴って、単板検出器１０による検出信号が一定時間以上途絶えるまでは、単板２に不要部分２ａが存在するか否かに拘わらず、同様の制御を繰返して、順次定尺単板２Ｂを形成し、上下二段の通路ａ・ｂへ交互に配送する。   Eventually, with the arrival of the single plate 2 to be cut, the detection signal from the single plate detector 10 is transmitted continuously for a predetermined time or longer, and most of the unnecessary portion 2a on the front end side is cut off. When the front end of the single plate 2 reaches the position of the standard detector 11 and a detection signal is transmitted from the standard detector 11, the open / close member 9 waiting at the position indicated by the solid line is indicated by a dotted line. The single plate 2 is moved to a position shown by closing the waste discharging path c, and the cutting blade 6 located at the position shown by the solid line is controlled to turn one way to the position shown by the dotted line, so that the single plate 2 is predetermined. A regular cut is made with a fixed dimension W (see FIG. 10), and the subsequent single plate 2 is caused to flow into the lower passage 2b. Next, when the front end of the single plate 2 that has flowed into the lower passage 2b reaches the position of the standard detector 12, and a detection signal is transmitted from the standard detector 12, the cutting at the position indicated by the dotted line By controlling the blade 6 to rotate one way to the position indicated by the solid line, the single plate 2 is cut again with a predetermined fixed dimension W. In the following, until the end of the single plate 2 arrives, until the detection signal by the single plate detector 10 is interrupted for a predetermined time or more, the same is true regardless of whether or not the unnecessary portion 2a exists in the single plate 2. By repeating the control, the single-sized single plate 2B is sequentially formed and delivered alternately to the upper and lower two-stage passages a and b.

そして、定尺切断が行われた以降に於ては、原則的に、定尺単板２Ｂが完全に上段のコンベア７上に移乗される状態となる都度（換言すると、定尺単板全体が上段のコンベア上に移乗される状態となる時間が経過する毎に）、所定期間だけ上段のコンベア７の稼動を休止してから、稼動を再開するように制御することにより、上段の通路ａを進行する定尺単板２Ｂが、下段の通路ｂを進行する定尺単板２Ｂの上に丁度重なり合うように合流させると共に（図５参照）、次の原木の旋削が新たに開始されるまでは、斯様な原則的な制御を維持することにより、定尺切断が偶数回行われて終了した場合については、定尺切断が終了した後に送出される残余の乱尺単板２Ａを、定尺単板２Ｂと同様に暫時待機させてから下段の通路ｂへ流入させる（図６参照）。一方、定尺切断が奇数回行われて終了した場合に限っては、例外的に、通常の所定期間の二倍を越える期間稼動を休止してから、稼動を再開するように制御することにより、上段の通路ａを進行する定尺単板２Ｂが、下段の通路ｂを進行する残余の乱尺単板２Ａと重なり合わないようにする（図８参照）。   After the standard cutting, in principle, each time the standard single plate 2B is completely transferred onto the upper conveyor 7 (in other words, the entire standard single plate is By controlling to stop the operation of the upper conveyor 7 for a predetermined period and then restart the operation (every time elapses when the state is transferred to the upper conveyor), the upper passage a The advancing standard veneer 2B joins the lower passage b so that it just overlaps the advancing standard veneer 2B (see FIG. 5), and until the next raw wood turning is newly started. By maintaining such basic control, when the regular cutting is finished even times, the remaining irregular single plate 2A sent out after the regular cutting is finished, Like the single plate 2B, after waiting for a while, it flows into the lower passage b ( See 6). On the other hand, only when the regular cutting is finished with an odd number of times, it is exceptionally controlled by stopping the operation for a period exceeding twice the normal predetermined period and then restarting the operation. The fixed single plate 2B traveling in the upper passage a is prevented from overlapping the remaining irregular single plate 2A traveling in the lower passage b (see FIG. 8).

また更に、制御機構Ｂは、述上の如き制御機能に加えて、下段の通路２ｂを介して次工程に流入する単板が、乱尺単板２Ａであるか定尺単板２Ｂであるかの情報（信号）を、後述する制御機構Ｄ・Ｆ等へ伝達する機能も併せて具備するよう構成する。   Furthermore, in addition to the control function as described above, the control mechanism B determines whether the single plate flowing into the next process through the lower passage 2b is the random single plate 2A or the fixed single plate 2B. This information (signal) is also configured to have a function of transmitting the information (signal) to a control mechanism D / F or the like to be described later.

Ｃは、公知の定尺単板堆積装置であって、前記下段コンベア７の後部上方に配設され、下段コンベア７と同速度で図示矢印方向へ連続的に走行して、乱尺単板２Ａ及び定尺単板２Ｂを刺着・搬送する刺着コンベア１３、図示矢印方向へ昇降自在な打落としバー１４、概ね一定の高さを以って落下する定尺単板２Ｂを堆積する昇降自在な堆積台１５等を具備し、後述する制御機構Ｄの制御を得て、刺着コンベア１３によって刺着・搬送される乱尺単板２Ａについては、最後部まで搬送してから徐々に刺着を開放することにより、刺着コンベア１３と同速度で図示矢印方向へ連続的に走行する中継コンベア１６へ順次移乗させると共に、定尺単板２Ｂについては、規定位置に至る都度、打落としバー１４を昇降させることにより、刺着を一斉に開放して、堆積台１５上に落下させる。   C is a known fixed-size veneer depositing device, which is disposed above the rear part of the lower conveyor 7 and continuously runs in the direction of the arrow shown in the figure at the same speed as the lower conveyor 7 so that the irregular veneer 2A Also, a sticking conveyor 13 for sticking and transporting the fixed-size veneer 2B, a dropping bar 14 that can be raised and lowered in the direction of the arrow shown in the figure, and an up-and-down move that deposits the fixed-length veneer 2B that falls with a substantially constant height. The random board 2A, which is equipped with a stacking table 15 and the like, is controlled by the control mechanism D described later, and is inserted and conveyed by the piercing conveyor 13, is gradually stuck after being transported to the end. Is opened, the transfer is sequentially transferred to the relay conveyor 16 that continuously travels in the direction of the arrow shown in the figure at the same speed as the stab conveyor 13, and for the single-sized single plate 2B, every time it reaches the specified position, the drop bar 14 Open and close the piercing at the same time To, is dropped onto the deposition table 15.

Ｄは、前記定尺単板堆積装置Ｃの制御機構であって、先記制御機構Ｂからの情報に基づき、刺着コンベア１３によって刺着・搬送される定尺単板２Ｂが、規定位置に至った場合に限って、打落としバー１４を昇降させるよう制御することにより、定尺単板２Ｂのみを堆積台１５上に落下させる。尚、定尺単板が、規定位置に至る時期は、制御機構からの情報に基づく時間の経過によって簡便に定め得るが、必要に応じては、規定位置に単板感知器を備え、該単板感知器の感知信号を併用して定めるよう構成しても差支えない。   D is a control mechanism of the above-mentioned fixed-size veneer stacking device C. Based on the information from the above-mentioned control mechanism B, the fixed-size veneer 2B to be pierced and conveyed by the piercing conveyor 13 is placed at a specified position. Only when it arrives, the fixed bar 2B alone is dropped on the deposition table 15 by controlling the dropping bar 14 to move up and down. The time when the standard single plate reaches the specified position can be easily determined by the passage of time based on information from the control mechanism. However, if necessary, the single plate is provided with a single plate sensor at the specified position. There may be a configuration in which the detection signal of the plate sensor is determined together.

Ｅは、公知の乱尺単板堆積装置であって、中継コンベア１６の後部上方に配設され、中継コンベア１６と同速度で図示矢印方向へ連続的に走行して、乱尺単板２Ａを刺着・搬送する刺着コンベア１７、図示矢印方向へ昇降自在な打落としバー１８、概ね一定の高さを以って落下する乱尺単板２Ａを堆積する昇降自在な堆積台１９等を具備し、後述する制御機構Ｆの制御を得て、刺着コンベア１７によって刺着・搬送される乱尺単板２Ａが、適宜位置に至る都度、打落としバー１８を昇降させることにより、乱尺単板２Ａの刺着を開放して、堆積台１９上に落下させる。   E is a known irregular veneer stacking device, which is disposed above the rear part of the relay conveyor 16 and continuously travels in the direction of the arrow shown in the figure at the same speed as the relay conveyor 16 to move the irregular veneer 2A. An insertion conveyor 17 for inserting and conveying, a dropping bar 18 that can be moved up and down in the direction of the arrow shown in the figure, and a stacking table 19 that can be moved up and down to deposit the irregular single plate 2A that falls with a substantially constant height. Then, under the control of the control mechanism F, which will be described later, each time the irregular single plate 2A that is punctured and transported by the puncture conveyor 17 reaches the appropriate position, the drop bar 18 is moved up and down, thereby causing the irregular single unit The piercing of the plate 2A is released and dropped onto the deposition table 19.

Ｆは、前記乱尺単板堆積装置Ｅの制御機構であって、先記制御機構Ｂからの情報に基づき、刺着コンベア１７によって刺着・搬送される乱尺単板２Ａが、適宜位置に至る都度、例えば乱尺単板２Ａの前端が規定位置に至る都度、或は例えば乱尺単板２Ａの後端が規定位置に至る都度、或は例えば乱尺単板２Ａが堆積台１９の中央上方に至る都度、更にはそれらの位置を一回乃至複数回づつ織り交ぜながら、打落としバー１８を昇降させるよう制御することにより、乱尺単板２Ａを堆積台１９上に落下させる。また、必要に応じて、規定の領域内に複数枚の乱尺単板２Ａが刺着・搬送された場合には、複数枚を一緒に落下させる制御を行うようにしても差支えない。   F is a control mechanism of the irregular single plate deposition apparatus E. Based on the information from the control mechanism B, the irregular single plate 2A to be stuck and transported by the sticking conveyor 17 is appropriately positioned. Every time, for example, every time the front end of the irregular single plate 2A reaches the prescribed position, or every time the rear end of the irregular single plate 2A reaches the prescribed position, or for example, the irregular single plate 2A becomes the center of the deposition table 19 Each time it reaches the upper side, it is controlled so as to raise and lower the dropping bar 18 while weaving these positions once or several times, thereby dropping the irregular single plate 2A onto the deposition table 19. In addition, if a plurality of irregularly-sized single plates 2A are stabbed and transported within a prescribed area, it is possible to perform control to drop the plurality of sheets together as necessary.

本発明に係る単板の処理方法は、例えば述上の如き構成で成る一連の処理ラインを用いて実施するものであって、ベニヤレースによって削成された単板２が、移送コンベア１を介して切断装置Ａに移送されると、単板２の不要部分２ａの大半を順次切除して屑の排出路ｃへ排出すると共に、上段のコンベア８、下段のコンベア７、定尺単板堆積装置Ｃの刺着コンベア１３、中継コンベア１６等を介して、乱尺単板２Ａを乱尺単板堆積装置Ｅへ移送して堆積処理し、更に定尺切断すべき単板２が到来した以降は、切断装置Ａによって、単板２を所定の定尺寸法毎に定尺切断することにより、順次定尺単板２Ｂを形成して、一旦上下二段のコンベア７・８上へ交互に配送すると共に、両コンベア７・８の合流位置に於て、二重状に重ね合わせてから定尺単板堆積装置Ｃに移送し、順次堆積処理するものであるから、総じて狭小のスペースを以って、乱尺単板と定尺単板とを弁別して堆積処理することが可能であるのは勿論のこと、原則的に、次の原木の旋削が新たに開始されるまでは、所定期間だけ上段のコンベア８の稼動を休止してから稼動を再開するよう、両コンベア７・８の稼動態様を維持することによって、定尺切断が偶数回行われて終了した場合については、図６に例示する如く、定尺切断が終了した後に送出される残余の乱尺単板２Ａを、定尺単板２Ｂと同様に暫時待機させてから下段の通路２ｂへ流入させるものであるから、該残余の乱尺単板２Ａを乱尺単板堆積装置Ｅへ移送して堆積処理するのに何等支障なく、更に、定尺切断が奇数回行われて終了した場合については、例外的に、通常の所定期間の二倍を越える期間上段のコンベア８の稼動を休止してから、稼動を再開するように制御することにより、図８に例示する如く、上段の通路ａを進行する定尺単板２Ｂが、下段の通路ｂを進行する残余の乱尺単板２Ａと重なり合わないようにするものであるから、やはり、残余の乱尺単板２Ａを乱尺単板堆積装置Ｅへ移送して堆積処理するのに何等支障なく、結果的に、残余の乱尺単板２Ａが定尺単板２Ｂの堆積山に混入する不具合を回避することができる。   The veneer processing method according to the present invention is performed using, for example, a series of processing lines configured as described above. A veneer laced veneer 2 passes through a transfer conveyor 1. Then, when transferred to the cutting device A, most of the unnecessary portions 2a of the veneer 2 are sequentially cut out and discharged to the waste discharge path c, and the upper conveyor 8, the lower conveyor 7, and the fixed veneer stacking device After the single plate 2 to be cut is measured after the irregular single plate 2A is transferred to the random single plate deposition apparatus E via the piercing conveyor 13 and the relay conveyor 16 of C, and the stacking process is performed. The cutting device A cuts the veneer 2 into predetermined lengths, thereby forming the fixed veneers 2B in sequence and temporarily delivers them alternately onto the upper and lower conveyors 7 and 8. At the same time, the two conveyors 7 and 8 are overlapped Since it is transferred to the fixed-size single plate deposition apparatus C and sequentially deposited, it is possible to discriminate the random-size single plate from the fixed-size single plate and perform the deposition processing with a generally small space. As a matter of course, in principle, until the next raw wood turning is newly started, both conveyors 7 and 8 are operated so that the upper conveyor 8 is stopped for a predetermined period and then restarted. By maintaining the operation mode, when the regular cutting is finished even number of times, the remaining irregular single plate 2A sent after the regular cutting is finished is fixed as shown in FIG. As in the case of the single veneer 2B, since it is made to wait for a while and then flows into the lower passage 2b, there is nothing to transfer the remaining irregular veneer 2A to the irregular veneer depositing apparatus E for the deposition process. If there is no hindrance and the regular cutting is finished an odd number of times Exceptionally, by controlling the upper conveyor 8 to suspend operation after a period exceeding twice the normal predetermined period, and to resume the operation, the upper passage a as shown in FIG. Since the advancing fixed-size veneer 2B does not overlap with the remaining turbulent veneer 2A that travels in the lower passage b, the remaining undulated veneer 2A is deposited on the undulated veneer. There is no problem in transporting to the apparatus E and depositing, and as a result, it is possible to avoid the problem that the remaining irregular single plate 2A is mixed into the piles of the fixed single plate 2B.

尚、前記実施例に於ては、定尺切断すべき単板の到来を、単板検出器で検出して検出信号を発信する構成としたが、斯様な検出信号の発信は、例えば先記切断装置の単板検知機構によって代用（兼用）させたり、或はベニヤレースの前位の心出し装置に於て、原木の最適旋削中心を算出する為に用いる仮想内接円筒の演算値を、流用・活用したりすることが可能であり、また、単板の末尾の到来は、例えばベニヤレースに於ける原木旋削の完了信号を活用して予測することも可能であるなど、他の手段に代替が可能であるので、必ずしも単板検出器を備えることが必須ではない。   In the above-described embodiment, the detection of the arrival of a single plate to be cut by a single plate is detected by a single plate detector, and the detection signal is transmitted. The calculated value of the virtual inscribed cylinder used to calculate the optimum turning center of the raw wood in the centering device in front of the veneer or substituted by the single plate detection mechanism of the cutting device It is possible to divert and utilize, and the arrival of the end of a veneer can also be predicted by utilizing the completion signal of the raw wood turning in the veneer race, for example. Therefore, it is not always necessary to provide a single plate detector.

また、前記実施例に於ては、切断装置の後位に設けた上段の通路に拘わる条件の内で、通路の稼動時間を適切に調整することによって、具体的には、所定期間だけ通路の稼動を休止してから、稼動を再開する稼動形態を採ることによって、上段の通路を通過する単板の前端が、両通路の合流位置に於て、下段の通路を通過する単板の前端と丁度重なり合うように設定したが、定尺単板を二重状に重ね合わせるのに適する条件としては、上段の通路の稼動時間の調整に限るものではなく、図示は省略したが、例えば上段の通路を折り返し状に迂回させるなど、上段の通路の長さを調整（好ましくは、定尺寸法の変化に適応できるよう、通路の長さを加減自在とする）しても差支えなく、或は例えば上段の通路の通行速度を所定期間だけ一時的に減速させるなど、上段の通路の通行速度を調整しても差支えなく、更には前記各条件を組合わせて用いることも可能であり、要は、定尺単板を二重状に重ね合わせることができれば足りる。   In the above embodiment, the passage time is appropriately adjusted within the conditions relating to the upper passage provided at the rear of the cutting device. By adopting an operation mode in which the operation is stopped and the operation is resumed, the front end of the veneer that passes through the upper passage is changed from the front end of the veneer that passes through the lower passage at the joining position of both passages. Although it is set so that it overlaps exactly, the conditions suitable for stacking the standard single plates in a double shape are not limited to the adjustment of the operating time of the upper passage, but are not shown, but for example, the upper passage The length of the upper passage can be adjusted (preferably, the length of the passage can be adjusted so that it can be adapted to changes in the standard size), such as by detouring in a folded shape, or for example, The passage speed of the passageway temporarily for a predetermined period It is possible to adjust the passage speed of the upper passage, such as speeding up, and it is also possible to use the above conditions in combination. It is enough if possible.

また、前記実施例に於ては、通常よりも余分に上段の通路の稼動を休止してから、稼動を再開する稼動形態を採ることによって、例外的に、上段の通路の稼動を暫時遅延させ、奇数枚目の定尺単板と残余の乱尺単板との重なり合いを回避するようにしたが、上段の通路の稼動を暫時遅延させる遅延手段としては、通路の稼動時間を調整する手段の外に、上段の通路の通行速度を所定期間だけ一時的に減速させるなど、上段の通路の通行速度を調整する手段でも差支えなく、而も、例えば折り返し状に迂回させた上段の通路の稼動を、規定の期間だけ停止させるなどの如く、前記各遅延手段はいずれも、前記定尺単板を二重状に重ね合わせるのに適する条件のいずれと組合わせて用いても差支えない。   Also, in the above embodiment, the operation of the upper passage is exceptionally delayed for a while by adopting an operation mode in which the operation of the upper passage is suspended more than usual and the operation is resumed. Although the overlap between the odd-numbered single plate and the remaining irregular single plate is avoided, the delay means for delaying the operation of the upper passage for a while is a means for adjusting the operation time of the passage. In addition, there is no problem with means for adjusting the passage speed of the upper passage, such as temporarily reducing the passage speed of the upper passage for a predetermined period. Each of the delay means may be used in combination with any of the conditions suitable for overlapping the fixed-size single plates in a double shape, such as stopping for a predetermined period.

また、前記実施例に例示した切断装置は、構造が比較的簡単であって、一連の処理ラインを構成するのに適するが、切断装置の形式としては、前記実施例の形式に限るものではなく、図示は省略したが、例えば「単板の切断装置」（特開平２−１４３８０１号公報）に開示される如く、刃先を単板の進行方向と逆向きに向けて備えた固定刃の前位に、複数列の円周方向に連なる多数の突刺体を有する刺着搬送体を備えると共に、前記突刺体の列の間に介在し、単板を固定刃の一方の面側と他方の面側とへ交互に案内する単板案内部材を備えて構成した切断装置、或は例えば「単板横はぎ機に於ける差動搬送装置」（特開昭５５−５８６７号公報）に開示される如く、２枚の可動刃を、一枚の固定刃に対峙してランニングカット可能に構成したツイン型ベニヤクリッパなど、同種の機能を奏する切断装置であれば、一連の処理ラインを構成するのに用いることができる。   Further, the cutting apparatus exemplified in the above embodiment is relatively simple in structure and suitable for forming a series of processing lines. However, the cutting apparatus is not limited to the above embodiment. Although not shown, for example, as disclosed in “Single plate cutting device” (Japanese Patent Laid-Open No. Hei 2-143801), the front of a fixed blade having a cutting edge facing in the direction opposite to the traveling direction of the single plate. A plurality of rows of piercing bodies connected in the circumferential direction, and a single plate interposed between the rows of the piercing bodies, on one side and the other side of the fixed blade A cutting device comprising a single plate guide member that alternately guides to the plate, or as disclosed in, for example, "Differential transfer device in a single plate horizontal stripper" (Japanese Patent Laid-Open No. 55-5867) Two movable blades are configured to be capable of running cut against one fixed blade. Such as in type veneer clipper, if the cutting device provides the functions of the same type, it can be used to construct a series of processing lines.

同様に、定尺単板堆積装置及び乱尺単板堆積装置の形式についても、前記実施例の形式に限るものではなく、例えば後述する単板接合堆積装置Ｇの堆積機構Ｄ３の如く、刺着コンベアに代えて開閉コンベアを備える形式など、同種の機能を奏する堆積装置であれば、一連の処理ラインを構成するのに用いることができる。更に、屑の排出路を開閉する開閉部材についても、前記実施例の揺動式に限るものではなく、図示は省略したが、例えば下段の通路の下方から斜めに出没する出没式であっても差支えなく、要は、適時屑の排出路を開閉することができる部材であれば足りる。   Similarly, the types of the fixed single plate deposition apparatus and the irregular single plate deposition apparatus are not limited to those of the above-described embodiments, and for example, as in a deposition mechanism D3 of the single plate bonding deposition apparatus G described later, sticking is performed. Any deposition apparatus that exhibits the same type of function, such as a type having an open / close conveyor instead of the conveyor, can be used to configure a series of processing lines. Furthermore, the opening / closing member that opens and closes the waste discharge path is not limited to the swinging type of the above-described embodiment, and is not shown in the figure. Of course, any member that can open and close the waste discharge path in a timely manner is sufficient.

また、前記実施例は、定尺単板堆積装置と乱尺単板堆積装置とを備えて、乱尺単板と定尺単板とを弁別して堆積処理する構成としたが、乱尺単板を所望の定尺寸法の接合単板に形成して堆積する単板接合堆積装置を、前記実施例の乱尺単板堆積装置に代えて備える構成としても差し支えなく、或は乱尺単板堆積装置と単板接合堆積装置とを併設する構成としても差し支えない。   Moreover, although the said Example was equipped with the fixed-size veneer deposition apparatus and the irregular-length veneer deposition apparatus, it was set as the structure which discriminate | determines a random-length veneer and a fixed-length veneer, and carries out the deposition process, A single plate joining and depositing apparatus that forms and deposits on a bonded single plate having a desired standard size may be used in place of the random single plate depositing apparatus of the above-described embodiment. There may be a configuration in which the apparatus and the single plate bonding deposition apparatus are provided side by side.

而して、乱尺単板堆積装置と単板接合堆積装置とを併設するに際しては、図３・図４に例示する如き連結形態とするのが好都合である。即ち、図３・図４に於て、２０は、分岐移送機構を単板移送方向上手側に備えて成り、必要に応じて、切断装置と単板接合堆積装置とを選択的に接続する連結移送機構を構成する連結コンベアであって、実線及び点線で示す如く、前記両通路ａ・ｂの合流位置と定尺単板堆積装置Ｃとの間に於ける下段の通路ｂに対して出没する方向に揺動自在な分岐コンベア２０ａを、単板移送方向上手側に備えると共に、下段のコンベア７と同速度（実質的にベニヤレースの単板旋削速度と同速度）で図示矢印方向へ連続的に走行し、而も前記分岐コンベア２０ａを、適時、図示矢印方向に可動させることにより、下段のコンベア７上から乱尺単板２Ａを分岐的に掬い上げ、後述する単板接合堆積装置Ｇへ移送する。   Thus, when the irregular single-plate deposition apparatus and the single-plate bonding deposition apparatus are provided side by side, it is convenient to adopt a connection configuration as illustrated in FIGS. That is, in FIGS. 3 and 4, reference numeral 20 is provided with a branch transfer mechanism on the upper side in the veneer transfer direction, and a connection for selectively connecting the cutting device and the veneer bonding deposition device as necessary. A connecting conveyor constituting a transfer mechanism, as shown by a solid line and a dotted line, appears and disappears with respect to a lower passage b between the joining position of both the passages a and b and the fixed plate stacking apparatus C. A branch conveyor 20a swingable in the direction is provided on the upper side of the single plate transfer direction, and continuously in the direction of the arrow shown in the drawing at the same speed as the lower conveyor 7 (substantially the same speed as the veneer single plate turning speed). By moving the branch conveyor 20a in the direction indicated by the arrow in a timely manner, the random single plate 2A is branched up from the lower conveyor 7 in a branching manner to a single plate bonding and deposition apparatus G to be described later. Transport.

尚、前記分岐コンベア２０ａの揺動は、先記制御機構Ｂによる乱尺単板２Ａと定尺単板２Ｂとの判別情報に基づき、流体シリンダ・カム・クランク等の作動部材（図示省略）を介して行うように構成して、基本的には、全ての乱尺単板２Ａを単板接合堆積装置Ｇへ移送することとし、非常時に限って、例えば単板接合堆積装置Ｇの接合材Ｔを補充する時、或は例えば接合単板２Ｃの堆積山を取出す時、更には乱尺単板２Ａの累積量が単板接合堆積装置Ｇの処理容量を越えた時などの非常時に限って、応急的に、定尺単板堆積装置Ｃを介して乱尺単板堆積装置Ｅに乱尺単板２Ａを移送するように揺動させるのが好ましいが、該好ましい態様とは別異の態様であっても何等差支えなく、また、その情報源としては、制御機構Ｂによる判別情報の外に、例えば単板接合堆積装置Ｇの作業者による手動操作信号などでも差支えなく、要は、所望時に、分岐的な掬い上げが開始或は休止できる情報源であれば足りる。   The swinging of the branch conveyor 20a is caused by operating members (not shown) such as a fluid cylinder, a cam, and a crank based on the discriminating information between the irregular single plate 2A and the fixed single plate 2B by the control mechanism B. Basically, all the irregular single plates 2A are transferred to the single plate bonding deposition apparatus G. For example, the bonding material T of the single plate bonding deposition apparatus G is used only in an emergency. For example, when removing the piles of the joined veneer 2C, or when the accumulated amount of the irregular veneer 2A exceeds the processing capacity of the veneer stacking apparatus G, As an emergency, it is preferable that the irregular single plate 2A is rocked so as to be transferred to the random single plate deposition apparatus E via the fixed single plate deposition apparatus C, but in a different manner from the preferred embodiment. There is no problem even if it exists, and the information source is outside the discrimination information by the control mechanism B. , For example, veneer bonding deposition apparatus not permissible in such a manual operation signal by the operator of G, short, when desired, sufficient that a branch specific scoop sources up can be started or paused.

Ｇは、本出願人が、先に「ベニヤ単板の接合方法及び接合装置」（特開２００３−２９１１０６号公報）に於て開示した、公知の単板接合堆積装置であって、後述する三つの主要な機構Ｇ１・Ｇ２・Ｇ３を具備して成り、乱尺単板２Ａの前後端部の不要部分２ａを順次切除して、先行する乱尺単板２Ａの後端部と後続する乱尺単板２Ａの前端部とを密接状に接近させると共に、該両端部を接合材Ｔによって接合し、併せて、接合せんとする乱尺単板２Ａの累積幅が所望の定尺寸法に達する毎に予め定尺切断を行うことにより、順次接合単板２Ｃを形成して堆積する。   G is a known single plate bonding deposition apparatus previously disclosed by the present applicant in “Junior veneer bonding method and bonding apparatus” (Japanese Patent Laid-Open No. 2003-291106). Two main mechanisms G1, G2, and G3, and the unnecessary portion 2a at the front and rear end portions of the irregular single plate 2A is sequentially cut out, followed by the rear end portion of the preceding irregular single plate 2A and the subsequent random portion. Each time the front end of the single plate 2A is brought into close contact with each other, both ends thereof are joined by the joining material T, and the accumulated width of the irregular single plate 2A to be joined together reaches a desired standard size. Then, a single cut 2C is sequentially formed and deposited by performing predetermined length cutting.

即ち、Ｇ１は、単板接合堆積装置Ｇの一つの要部を形成する切断機構であって、例えば作業者が乱尺単板２Ａの姿勢を修正し得る程度の搬送速度を以って、後述する溝付アンビルロール２２の間歇回転に同調して図示矢印方向へ間歇的に走行する搬入コンベア２１、後述する切断刃２３による単板切断時に暫時停止する以外は、搬入コンベア２１と同速度で図示矢印方向へ回転する刃受体兼用の溝付アンビルロール２２、単板検知機構２４の検知信号に基づく制御機構（図示省略）の制御を得て、乱尺単板２Ａの有効部分と前後端部の不要部分２ａとの境界を切断する切断刃２３、同じく制御機構の制御を得て、乱尺単板２Ａの有効部分と前後端部の不要部分２ａとの通路を交互に切替える選別開閉体２５、上下一対の挟持コンベア２６・２７等を具備し、乱尺単板２Ａの前後端部の不要部分２ａを順次切除して、先行する乱尺単板２Ａの後端部と後続する乱尺単板２Ａの前端部とを密接状に接近させると共に、該接近状態を維持しつつ、複数枚の乱尺単板２Ａを後述する堆積機構Ｇ３へ移送する。但し、切断刃は、図示しない制御機構の制御を得て、前記境界の切断動作と共に、接合せんとする乱尺単板の累積幅が所望の定尺寸法（例えば、定尺単板の定尺寸法と同等の寸法Ｗ）に達する毎の定尺切断をも併せて行う。   That is, G1 is a cutting mechanism that forms one main part of the single plate bonding and deposition apparatus G, and will be described later, for example, with a conveyance speed at which the operator can correct the posture of the irregular single plate 2A. Except at the same time as the carry-in conveyor 21 except that the carry-in conveyor 21 that runs intermittently in the direction of the arrow shown in synchronization with the intermittent rotation of the grooved anvil roll 22 and the single-cutting by the cutting blade 23 that will be described later is stopped for a while. An effective portion and front and rear end portions of the irregular single plate 2A are obtained by controlling the control mechanism (not shown) based on the detection signal of the grooved anvil roll 22 that also serves as the blade receiver rotating in the direction of the arrow and the single plate detection mechanism 24. A cutting blade 23 that cuts the boundary with the unnecessary portion 2a, and a selection opening / closing body 25 that alternately switches the path between the effective portion of the random single plate 2A and the unnecessary portion 2a at the front and rear end portions under the control of the control mechanism. A pair of upper and lower clamping conveyors 26.2 Etc., and unnecessary portions 2a at the front and rear end portions of the irregular single plate 2A are sequentially cut out so that the rear end portion of the preceding random single plate 2A and the front end portion of the subsequent random single plate 2A are in close contact with each other. And a plurality of random single plates 2A are transferred to a deposition mechanism G3, which will be described later, while maintaining the approaching state. However, the cutting blade is controlled by a control mechanism (not shown), and along with the cutting operation of the boundary, the accumulated width of the random single plate to be joined is a desired standard size (for example, the standard size of the standard single plate). A regular cut is also performed each time a dimension W) equivalent to the method is reached.

Ｇ２は、単板接合堆積装置Ｇの別の要部を形成する接合機構であって、例えば再湿性接着テープなどの接合材Ｔを適量づつ繰出し、ガイド部材２９を介して、接合材Ｔを、乱尺単板２Ａと後述する加圧部材３０との間に供給すると共に、該加圧部材３０による接合材Ｔの加圧時に、少量の繰戻しを行って、接合材Ｔの分断を助長する繰出しロール２８と、必要に応じて、分断刃の付設などの接合材Ｔの分断機能と、電熱器の付設などの加熱機能とを具備し、適時、図示矢印方向へ昇降して、乱尺単板２Ａへの接合材Ｔの接着を行う加圧部材３０とを少なくとも用いて構成された接合ユニットＧａ、図示しない制御機構の制御を得て、該接合ユニットＧａを常時適切な位置に移動させる移動ネジ３１等を具備し、前記切断機構Ｇ１の挟持コンベア２６・２７によって挟持搬送される先行する乱尺単板２Ａの後端部と後続する乱尺単板２Ａの前端部を、接合材Ｔによって接合する（図９参照）。但し、定尺切断された切断個所につては接合を行わない。   G2 is a joining mechanism that forms another main part of the single-plate joining / depositing device G, and for example, an appropriate amount of joining material T such as a rewet adhesive tape is fed out, and the joining material T is passed through the guide member 29. While supplying between the irregular single plate 2A and the pressurizing member 30 to be described later, a small amount of feeding is performed at the time of pressurization of the joining material T by the pressurizing member 30 to promote the division of the joining material T. It is equipped with a feeding roll 28 and, if necessary, a cutting function of the joining material T such as attachment of a cutting blade, and a heating function such as attachment of an electric heater. The joining unit Ga configured using at least the pressure member 30 for adhering the joining material T to the plate 2A, and the movement for constantly moving the joining unit Ga to an appropriate position by obtaining control of a control mechanism (not shown). A screw 31 or the like, and a clamping conveyor for the cutting mechanism G1 The front end portion of the turbulent continuous veneer 2A and the subsequent rear portion of the turbulent continuous veneer 2A preceding is nipped and conveyed by the 26, 27, joined by a bonding material T (see FIG. 9). However, joining is not performed on the cut portions that have been cut by the standard length.

前記接合ユニットＧａの移動形態の詳細について言及すると、接合ユニットＧａは、前記切断機構Ｇ１の切断実施位置（実質的に、切断刃２３の位置）から所定距離だけ隔てて設定された、一定の長さを有する加圧実施領域の域内を前後移動自在に備える。そして、該加圧実施領域内に、接合すべき複数枚の乱尺単板２Ａの後端部と前端部が進入すると、加圧部材３０の位置が、接合すべき両端部の位置に合致するよう、接合ユニットＧａの位置を移動させ、而も、加圧部材３０の加圧時には、乱尺単板２Ａの進行に適合して（乱尺単板２Ａの進行速度と同速度で）、接合ユニットＧａの位置を移動させ、乱尺単板２Ａの進行を阻害しないよう構成する。因に、加圧実施領域の域内に、接合すべき前後端部が相前後して一度にニ個所乃至はそれ以上流入することもあるが、この場合には、常に最も単板進行方向下手側に位置する接合すべき前後端部の位置に、加圧部材３０の位置を合致させ、接合材Ｔの加圧接着を終えた後で、次に最も単板進行方向下手側に位置する接合すべき前後端部の位置に、加圧部材３０の位置を合致させ、必要に応じて移動させるよう（単板が移動しなければ、接合ユニットを移動させる必要はない）構成する。また、加圧実施領域の域内に、接合すべき前後端部が存在しない時には、加圧実施領域の最も単板進行方向上手側の位置に、加圧部材３０の位置を合致させるよう接合ユニットＧａを移動させ、次の接合すべき前後端部の流入を待機させるよう構成する。斯様な位置の制御は、加圧実施領域の所在位置を予め定めておくことにより、切断機構Ｇ１の切断実施信号を活用して容易に実施できる。   Referring to the details of the movement mode of the joining unit Ga, the joining unit Ga is a fixed length set at a predetermined distance from the cutting execution position (substantially the position of the cutting blade 23) of the cutting mechanism G1. A pressurizing area having a thickness is provided so as to be movable back and forth. Then, when the rear end portion and the front end portion of the plurality of random single plates 2A to be joined enter the pressurizing execution region, the position of the pressurizing member 30 matches the position of both end portions to be joined. The position of the joining unit Ga is moved so that, when the pressurizing member 30 is pressed, it is adapted to the progress of the irregular single plate 2A (at the same speed as the traveling speed of the random single plate 2A). The position of the unit Ga is moved so as not to hinder the progress of the irregular single plate 2A. Incidentally, the front and rear end portions to be joined may flow into one place or more at a time in the region where the pressure is applied. The position of the pressure member 30 is matched with the position of the front and rear end portions to be bonded, and after the pressure bonding of the bonding material T is finished, the bonding next to the lowermost side in the single plate traveling direction is performed next. The position of the pressure member 30 is made to coincide with the position of the front and rear ends, and is moved as necessary (if the single plate does not move, it is not necessary to move the joining unit). Further, when there are no front and rear end portions to be joined within the area of the pressurizing area, the joining unit Ga is set so that the position of the pressurizing member 30 is aligned with the position closest to the single plate traveling direction in the pressurizing area. Is moved to wait for the next inflow at the front and rear ends to be joined. Such position control can be easily performed using the cutting execution signal of the cutting mechanism G1 by predetermining the location of the pressurizing execution area.

Ｇ３は、単板接合堆積装置Ｇの一部を構成する堆積機構であって、単板進行方向の左右へ開閉自在に備えられ、通常は切断機構Ｇ１の挟持コンベア２６・２７に同期して図示矢印方向へ間歇的に走行すると共に、接合単板２Ｃが完全に移乗される状態となる都度、短期的に増速走行してから通常通りに復帰する開閉コンベア３２、概ね一定の高さを以って落下する接合単板２Ｃを堆積する昇降自在な堆積台３３等を具備し、制御機構の制御を得て、開閉コンベア３２によって搬送される接合単板２Ｃが、適宜位置に至る都度、開閉コンベア３２を開閉させることにより、接合単板２Ｃを堆積台３３上に落下させる。   G3 is a deposition mechanism that constitutes a part of the single plate bonding deposition apparatus G, and is provided so as to be openable and closable to the left and right in the direction of travel of the single plate. Each time the joint veneer 2C travels intermittently in the direction of the arrow, and the joint veneer 2C is completely transferred, the opening / closing conveyor 32 that returns to the normal speed after traveling at an increased speed in a short period of time has a substantially constant height. Each time the joining veneer 2C conveyed by the open / close conveyor 32 is appropriately opened / closed with the control of the control mechanism, the stacking plate 33, etc., which can be moved up and down is deposited. By opening and closing the conveyor 32, the bonded single plate 2C is dropped onto the deposition table 33.

例えば述上の如き構成で成る単板接合堆積装置を、図１・図２に例示した一連の処理ラインに併設し、基本的に、全ての乱尺単板２Ａを単板接合堆積装置Ｇへ移送して、図９に例示する如き接合単板２Ｃに形成してから、堆積処理するようにすれば、以降の処理工程に於ける単板の取扱いが一段と簡便になるので有益であるのは勿論のこと、実施例に例示した連結コンベアなどの連結移送機構を介して、切断装置と単板接合堆積装置とを選択的に接続する構成によれば、単板接合堆積装置の接合材を補充する時などの非常時にも、ベニヤレースによる単板旋削を中止することなく、乱尺単板及び定尺単板を取得する処理が可能であり、総じて処理の充実化が図り得るので有益である。   For example, a single plate bonding deposition apparatus configured as described above is provided in the series of processing lines illustrated in FIGS. 1 and 2, and basically all the irregular single plates 2A are transferred to the single plate bonding deposition apparatus G. If it is transferred and formed into a bonded single plate 2C as illustrated in FIG. 9 and then deposited, the handling of the single plate in the subsequent processing steps is further simplified, which is beneficial. Of course, according to the configuration in which the cutting device and the single plate bonding / depositing device are selectively connected via the connecting / transferring mechanism such as the connecting conveyor illustrated in the embodiment, the bonding material of the single plate bonding / depositing device is replenished. In the event of an emergency, it is possible to acquire irregular and single-size veneers without stopping the veneer-cutting veneer turning, which is beneficial as the overall processing can be enhanced. .

因に、前記実施例に於ける単板接合堆積装置の接合機構は、前述の如く、単板の進行に対応して移動させながら接合動作を行わせることにより、単板の進行を阻害しないよう構成したものであるから、接合に要する時間が比較的長くなる未乾燥単板の接合には好適であって、能率良く接合処理を行うことができるが、本発明の実施に用いる単板接合堆積装置の形式としては、前記実施例の形式に限るものではなく、図示は省略したが、例えば単板の繊維と直交方向に適数条の切り溝を形成すると共に、該切り溝内へ接着剤と一緒に糸等の線材を埋入する形式などでも差支えなく、要は、乱尺単板を所望の定尺寸法の接合単板に形成して堆積することができれば足り、必要に応じて、定尺切断専用の切断機構を、堆積機構の前位へ別途に備えた形式であっても差支えない。   Incidentally, the bonding mechanism of the single plate bonding deposition apparatus in the above embodiment does not hinder the progress of the single plate by performing the bonding operation while moving in accordance with the progress of the single plate as described above. Since it is configured, it is suitable for bonding of undried single plates in which the time required for bonding is comparatively long, and can perform the bonding process efficiently, but the single plate bonding deposition used in the practice of the present invention The form of the apparatus is not limited to the form of the above-described embodiment, and illustration is omitted. For example, an appropriate number of kerfs are formed in a direction orthogonal to the fibers of the single plate, and an adhesive is formed in the kerfs. There is no problem even in the form of embedding a wire such as a thread together with the material, in short, it is sufficient if the irregular single plate can be formed and deposited on a bonded single plate of a desired standard size, if necessary, A cutting mechanism dedicated to regular cutting was separately provided in front of the deposition mechanism. No problem even in the equation.

尚、先記実施例に於ては、下段のコンベアから掬い上げた乱尺単板を、各枚毎に都度速やかに単板接合堆積装置に向けて移送するよう、連結移送機構を構成する連結コンベアの走行速度を、下段のコンベアと同速度として、常に連続的に走行させるよう構成したが、必要に応じては、別の態様、例えば下段のコンベアから乱尺単板を掬い上げる際には、先行する乱尺単板の掬い上げが完了する都度、一時的に走行を中止し、次に後続する乱尺単板の掬い上げを開始する都度、走行を再開するようにして、乱尺単板同士の間隔を、概ね一定の狭少間隔に詰寄せると共に、乱尺単板の到来が途絶えたら、一群の乱尺単板群を、速やかに単板接合堆積装置に向けて移送し、而も乱尺単板群の最先端部の乱尺単板が単板接合堆積装置の搬入コンベアに到達した後は、該搬入コンベアの間歇走行に同期させて、連結コンベアを間歇走行させる別の態様としても差支えなく、斯様な別の態様によれば、乱尺単板の総量が少ない時に、単板接合堆積装置に乱尺単板群が到来しない空白期間が比較的長く生じるので、他の工程から取得した他の乱尺単板等を、別途に単板接合堆積装置へ割り込ませて処理することが可能となる。また、斯様な別の態様を実施する場合に、必要に応じては、連結移送機構を複数に分別し、各部分毎に間歇走行させる時期を制御するようにしても差支えない。   In the above-mentioned embodiment, the connecting transfer mechanism is configured so that the irregularly measured single plates raised from the lower conveyor are quickly transferred to the single plate joining and depositing apparatus for each sheet. The conveyor travel speed is the same as that of the lower conveyor, and it is configured to always run continuously. However, if necessary, another mode, for example, when scooping up a random board from the lower conveyor Each time the preceding irregular-sized single plate is completely lifted, the traveling is temporarily stopped, and each time the subsequent succeeding irregular-sized single plate is started, the traveling is resumed. When the intervals between the plates are reduced to a substantially constant narrow interval, and the arrival of the irregular single plates stops, the group of irregular single plates is quickly transferred to the single plate bonding deposition apparatus. Even the leading edge of the random-sized single plate group is used as the carry-in conveyor of the single-plate joining and stacking equipment. After reaching, there is no problem even in another mode of intermittently running the connected conveyor in synchronization with the intermittent running of the carry-in conveyor, according to such another mode, when the total amount of the irregular single plate is small, Since the blank period during which the random single plate group does not arrive in the single plate bonding / depositing device occurs for a relatively long time, other irregular single plates obtained from other processes are separately interrupted and processed in the single plate bonding / depositing device. It becomes possible to do. Moreover, when implementing such another aspect, if necessary, the connection transfer mechanism may be divided into a plurality of parts, and the timing of intermittent running may be controlled for each part.

また一方、定尺単板堆積装置の後位に少なくとも単板接合堆積装置を設けることを前提条件として、例えば図１０に例示する如く、単板２の末尾２ｅ近い部分に於て、最後の定尺切断を行う際に、該最後の定尺切断が、奇数回目の定尺切断に相当し、而も所定の定尺寸法Ｗを以って定尺切断を行ったと仮定すると、残余の単板の幅αが、規定の最少限度幅（単板の性状・乾燥装置の構造・単板接合堆積装置の機能等の関連条件を勘案して、適宜設定すれば良い）以下となる場合に限っては、特例として、最後の定尺切断を中止すると共に、定尺単板２Ｂよりも幅の広い乱尺単板２Ａを、連結移送機構を介して単板接合堆積装置に移送し、接合単板に形成して堆積する処理を行うにすれば、残余の単板が筒状に丸まって後工程へ円滑に流れなくなる不都合が発生し難くなるのは勿論のこと、残余の単板が単板繊維の方向に沿って割れて利用が不能化する確率が低下し、而も前記切断予定線の左右に生じ易い歪の修正が無用となると共に、該歪の修正に起因して単板接合堆積装等に於ける利用可能な最少幅を得ることが困難化する確率も低下するなど、単板歩留りを低下させる諸要因を消去乃至は大幅に低減させることができ、総じて単板歩留りが向上するので有益である。   On the other hand, on the premise that at least a single plate bonding deposition device is provided at the rear of the single plate deposition device, for example, as shown in FIG. Assuming that the last regular cut corresponds to the odd-numbered regular cut, and that the regular cut was performed with a predetermined standard dimension W, the remaining single plate Only if the width α is less than or equal to the specified minimum width (appropriately set in consideration of related conditions such as the properties of the single plate, the structure of the drying device, the function of the single plate bonding deposition device, etc.) As a special case, the final cutting is stopped, and the irregular single plate 2A, which is wider than the fixed single plate 2B, is transferred to the single plate bonding / depositing device via the connection transfer mechanism. If the process of forming and depositing is performed, the remaining veneer will be rounded into a cylindrical shape and will not flow smoothly to the subsequent process. Of course, the probability that the remaining veneer breaks along the direction of the veneer fiber and becomes unusable will be reduced, and distortion that tends to occur on the left and right sides of the planned cutting line is reduced. As a result, it is not necessary to modify the strain, and the probability that it becomes difficult to obtain the minimum width that can be used in the single-plate bonding depositor etc. due to the correction of the strain is reduced. The factors can be eliminated or greatly reduced, and the single plate yield is generally improved, which is beneficial.

尚、図１・図２に例示した一連の直結ラインに於て、上下二段のコンベアを各別に間歇走行可能に備え、単板の流入が途絶える都度、走行を中止させるよう制御することによって、乱尺単板同士の間隔を、概ね一定の狭少間隔に詰寄せると共に、乱尺単板群の先端が定尺検出器の位置に至る都度、定尺切断を行うよう制御する構成を採れば、所定の定尺寸法の乱尺単板群を二重状に重ね合わせて、乱尺単板堆積装置に移送し、堆積処理することも可能である。因に、斯様な構成であっても、定尺切断すべき単板が到来した時には、単板の流入が途絶えないので、上下二段のコンベアの走行が中止されることはなく、定尺単板の生産性には全く影響はない。   In the series of direct connection lines illustrated in FIG. 1 and FIG. 2, the upper and lower conveyors are provided so that they can run intermittently, and control is performed so as to stop running each time the inflow of a single plate stops. If a configuration is adopted in which the intervals between the irregular single plates are gathered to a substantially constant narrow interval, and each time the leading end of the irregular single plate group reaches the position of the standard detector, control is performed to perform standard cutting. It is also possible to stack a group of irregular single plates having a predetermined standard size in a double shape and transfer them to a random single plate deposition apparatus for deposition treatment. Incidentally, even in such a configuration, when a single plate to be cut is arriving, the inflow of the single plate is not interrupted. There is no impact on the productivity of the veneer.
