Description

本発明は、木質系建築材料の製造装置および製造方法に関する。 The present invention relates to a manufacturing apparatus and a manufacturing method for wood-based building materials.

従来、木材から製造された木質系建築材料として、例えばＣＬＴ（Cross Laminated Timber：直交集成板）や集成材、合板、ＬＶＬ（Laminated Veneer Lumber：単板積層材）等が知られている（例えば特許文献１，２参照）。
これらの木質系建築材料は、複数の板材同士が重ねられ、接着剤によって貼り合わされることにより製造されている。また、木質系建築材料を製造するに当たっては、複数の板材同士を接着する接着剤として瞬間接着剤と硬化促進剤とが用いられ、極力短時間で接着する方法が採られていた。 Conventionally, as wood-based building materials manufactured from wood, for example, CLT (Cross Laminated Timber), laminated wood, plywood, LVL (Laminated Veneer Lumber), etc. are known (for example, patent). See Documents 1 and 2).
These wood-based building materials are manufactured by stacking a plurality of plate materials and adhering them with an adhesive. Further, in manufacturing a wood-based building material, an instant adhesive and a curing accelerator are used as an adhesive for adhering a plurality of plate materials to each other, and a method of adhering them in as short a time as possible has been adopted.

ところで、複数の板材同士を接着剤によって貼り合わせる場合、まずは一枚の板材と他の一枚の板材とを接着した後に、当該二枚分の板材と他の一枚の板材とを接着し、その後プレス機で圧縮する方法が採られていた。しかしながら、このような手順で木質系建築材料を製造すると、出来上がるまでに時間がかかるだけでなく、プレス機で圧縮する前に接着剤の硬化が始まり、品質の向上を図ることが難しい場合があった。 By the way, when a plurality of plate materials are bonded to each other with an adhesive, first, one plate material and another plate material are bonded, and then the two plate materials and the other plate material are bonded to each other. After that, the method of compressing with a press machine was adopted.

More specifically, the plurality of material plates 3a constituting the middle layer plate material 3 are sandwiched by the clamp portion 22a, and the plurality of material plates 3a sandwiched by the clamp portion 22a and the clamp portion 22a by a moving means (not shown) are used as the lower layer plate material. It is moved onto a plurality of material plates 2a constituting 2. That is, the plurality of material plates 3a are moved from the parallel sub-transfer section 20 to the main transfer section 10. Then, the plurality of material plates 3a that have moved to the top of the plurality of material plates 2a are released from being sandwiched by the clamp portion 22a and stacked on the lower plate material 2.

続いて、上層板材４を、反転積載装置３２によって、下層板材２に重ねられた中層板材３の上に上下反転移動させて重ねる（ステップＳ１１）。
より詳細には、上層板材４を構成する複数の材料用板４ａを保持手段（図示せず）によって保持した状態で回転軸部３２ａを回転させ、これに伴って、複数のアーム部３２ｂによって複数の材料用板４ａを持ち上げる。そして、さらに回転軸部３２ａを回転させることによって、上層板材４を構成する複数の材料用板４ａを、下層板材２を構成する複数の材料用板２ａの上に移動させる。すなわち、複数の材料用板４ａを分岐サブ移送部３０からメイン移送部１０に移動させる。そして、複数の材料用板２ａの上まで移動した複数の材料用板４ａを、保持手段による挟み込みを解除して下層板材２の上に重ねる。 Subsequently, the upper plate material 4 is vertically inverted and stacked on the middle layer plate material 3 stacked on the lower plate material 2 by the reversing loading device 32 (step S11).
More specifically, the rotary shaft portion 32a is rotated while the plurality of material plates 4a constituting the upper plate material 4 are held by the holding means (not shown), and a plurality of arm portions 32b are used accordingly. Lift the material plate 4a of. Then, by further rotating the rotation shaft portion 32a, the plurality of material plates 4a constituting the upper layer plate material 4 are moved onto the plurality of material plates 2a constituting the lower layer plate material 2. That is, the plurality of material plates 4a are moved from the branch sub-transfer section 30 to the main transfer section 10. Then, the plurality of material plates 4a that have moved to the top of the plurality of material plates 2a are released from being sandwiched by the holding means and stacked on the lower plate material 2.

続いて、互いに重ねられた下層板材２と中層板材３と上層板材４とをプレス装置１３まで移送する（ステップＳ１２）。
そして、プレス装置１３によって互いに重ねられた下層板材２と中層板材３と上層板材４のプレス作業を行う（ステップＳ１３）。プレス装置１３によって高圧のプレス作業が行われることにより、接着剤と硬化促進剤とが混合され、下層板材２と中層板材３と上層板材４の接着が素早く行われる。
なお、下層板材２と中層板材３と上層板材４とをプレス装置１３まで移送した後に、次の木質系建築材料１の製造を開始することができるので、木質系建築材料１の連続生産が可能となる。 Subsequently, the lower plate material 2, the middle layer plate material 3, and the upper layer plate material 4 that are overlapped with each other are transferred to the press device 13 (step S12).
Then, the lower plate material 2, the middle layer plate material 3, and the upper layer plate material 4 that are overlapped with each other by the press device 13 are pressed (step S13). By performing the high-pressure pressing operation by the pressing device 13, the adhesive and the curing accelerator are mixed, and the lower layer plate material 2, the middle layer plate material 3, and the upper layer plate material 4 are quickly bonded.
After the lower plate material 2, the middle layer plate material 3, and the upper layer plate material 4 are transferred to the press device 13, the production of the next wood-based building material 1 can be started, so that the wood-based building material 1 can be continuously produced. Will be.

プレス作業を終えた状態の下層板材２と中層板材３と上層板材４は、木質系建築材料１として下流側の積み取り装置１４が設けられた位置まで移送される（ステップＳ１４）。
そして、木質系建築材料１を、積み取り装置１４によってメイン移送部１０のルートから外して、図示しない台車や運搬用パレット等の上に積み重ねる（ステップＳ１５）。
以上のようにして、一つの木質系建築材料１を製造することができる。 The lower plate material 2, the middle layer plate material 3, and the upper layer plate material 4 in the state where the pressing work is completed are transferred to the position where the loading device 14 on the downstream side is provided as the wood-based building material 1 (step S14).
Then, the wood-based building material 1 is removed from the route of the main transfer unit 10 by the loading device 14 and stacked on a trolley, a transport pallet, or the like (step S15) (not shown).
As described above, one wood-based building material 1 can be manufactured.

このような木質系建築材料１の製造方法によれば、上向き面に接着剤が付着した状態の下層板材２と、上向き面と下向き面に硬化促進剤が付着した状態の中層板材３と、上向き面に接着剤が付着した状態の上層板材４とを積載作業領域Ａに別々に移送し、移動積載手段２２と反転積載手段３２とを用いて同じ場所（すなわち、積載作業領域Ａ）で重ねるので、下層板材２と中層板材３と上層板材４を短時間で重ねてプレス作業部１３へと移送することができる。
また、下層板材２と中層板材３と上層板材４を短時間で重ねた直後に、積載作業領域Ａの下流側に隣接するプレス作業部１３で圧縮することができるので、接着剤の硬化が進む前に、下層板材２と中層板材３と上層板材４を圧縮できる。
これによって、品質に優れた木質系建築材料を短時間で製造できる。
なお、以上のような製造方法においては、移動積載手段２２と反転積載手段２３を用いずに手作業で各板材２，３，４を積み重ねる作業を行ってもよい。 According to the method for producing the wood-based building material 1, the lower plate material 2 in which the adhesive is attached to the upward surface, the middle layer plate material 3 in which the curing accelerator is attached to the upward surface and the downward surface, and the upward direction. Since the upper plate material 4 with the adhesive adhered to the surface is separately transferred to the loading work area A and stacked at the same place (that is, the loading work area A) by using the mobile loading means 22 and the reversing loading means 32. The lower plate material 2, the middle layer plate material 3, and the upper layer plate material 4 can be stacked and transferred to the pressing work unit 13 in a short time.
Further, immediately after stacking the lower plate material 2, the middle layer plate material 3, and the upper layer plate material 4 in a short time, the adhesive can be compressed by the press working portion 13 adjacent to the downstream side of the loading work area A, so that the adhesive is hardened. Before, the lower plate material 2, the middle layer plate material 3, and the upper layer plate material 4 can be compressed.
As a result, it is possible to produce a wood-based building material having excellent quality in a short time.
In the manufacturing method as described above, the work of manually stacking the plate materials 2, 3 and 4 may be performed without using the mobile loading means 22 and the reversing loading means 23.

五層構造の木質系建築材料１００を製造する場合は、下層板材２と中層板材３と上層板材４が互いに重ねられて貼り合わされてなる木質系建築材料１を、下層板材２の代わりに、第三投入装置１５からメイン移送部１０に対して投入する。
すなわち、図５に示すステップＳ７において下層板材２の代わりに、木質系建築材料１を投入して移送する。その後は、木質系建築材料１を製造する場合と同様のステップで製造を進める。これによって、五層構造の木質系建築材料１００を製造することができる。
なお、五層構造の木質系建築材料１００に限らず、三層を超える層構造の木質系建築材料を製造する場合も同様のステップで容易に製造することができる。 In the case of manufacturing the five-layered wood-based building material 100, the wood-based building material 1 in which the lower-layer plate material 2, the middle-layer plate material 3, and the upper-layer plate material 4 are laminated and bonded to each other is used instead of the lower-layer plate material 2. (3) Loading is performed from the charging device 15 to the main transfer unit 10.
That is, in step S7 shown in FIG. 5, the wood-based building material 1 is charged and transferred instead of the lower plate material 2. After that, the production proceeds in the same steps as in the case of producing the wood-based building material 1. Thereby, the wood-based building material 100 having a five-layer structure can be manufactured.
It should be noted that not only the five-layered wood-based building material 100 but also a three-layered wood-based building material having more than three layers can be easily produced by the same steps.

本実施の形態によれば、積載作業領域Ａに別々に移送された、上向き面に接着剤が付着した状態の下層板材２と、上向き面と下向き面に硬化促進剤が付着した状態の中層板材３と、上向き面に接着剤が付着した状態の上層板材４が、移動積載手段２２と反転積載手段３２とを用いて同じ場所（すなわち、積載作業領域Ａ）で重ねられるので、下層板材２と中層板材３と上層板材４を短時間で重ねてプレス作業部１３へと移送することができる。
また、短時間で重ねられた下層板材２と中層板材３と上層板材４を、積載作業領域Ａの下流側に隣接するプレス作業部１３で圧縮することができるので、接着剤の硬化が進む前に、下層板材２と中層板材３と上層板材４を圧縮できるようになる。
これによって、品質に優れた木質系建築材料１を短時間で製造できる。
さらに、下層板材２と中層板材３と上層板材４とを重ねる作業を同じ場所で行うことができるとともに、積載作業領域Ａで作業を行った直後にプレス作業部１３でプレス作業を行うことができるような構成であるため、装置Ｌの大型化を防ぐことができる。 According to the present embodiment, the lower layer plate material 2 in which the adhesive is attached to the upward surface and the middle layer plate material in which the curing accelerator is attached to the upward surface and the downward surface, which are separately transferred to the loading work area A. 3 and the upper layer plate material 4 with the adhesive adhered to the upward surface are stacked at the same place (that is, the loading work area A) by using the mobile loading means 22 and the reversing loading means 32, so that the lower layer plate material 2 and the lower layer plate material 2 are stacked. The middle-layer plate material 3 and the upper-layer plate material 4 can be stacked and transferred to the pressing work unit 13 in a short time.
Further, since the lower plate material 2, the middle layer plate material 3, and the upper layer plate material 4 stacked in a short time can be compressed by the press working portion 13 adjacent to the downstream side of the loading work area A, before the adhesive is cured. In addition, the lower plate material 2, the middle layer plate material 3, and the upper layer plate material 4 can be compressed.
As a result, the wood-based building material 1 having excellent quality can be manufactured in a short time.
Further, the work of stacking the lower layer plate material 2, the middle layer plate material 3, and the upper layer plate material 4 can be performed at the same place, and the press work can be performed by the press work unit 13 immediately after the work is performed in the loading work area A. With such a configuration, it is possible to prevent the device L from becoming large.

また、積載作業領域Ａを通過するメイン移送部１０と、メイン移送部１０と平行する平行サブ移送部２０と、メイン移送部１０から分岐する分岐サブ移送部３０と、を備えるので、下層板材２と中層板材３と上層板材４を、積載作業領域Ａまで別々に移送することができる。また、下層板材２と中層板材３と上層板材４を別々に移送できれば、投入や移送のタイミングを調整することにより、下層板材２と中層板材３と上層板材４を効率よく移送でき、木質系建築材料１，１００を短時間で製造することが可能となる。 Further, since the main transfer section 10 passing through the loading work area A, the parallel sub transfer section 20 parallel to the main transfer section 10, and the branch sub transfer section 30 branching from the main transfer section 10 are provided, the lower plate material 2 is provided. And the middle layer plate material 3 and the upper layer plate material 4 can be separately transferred to the loading work area A. Further, if the lower plate material 2, the middle layer plate material 3 and the upper layer plate material 4 can be transferred separately, the lower layer plate material 2, the middle layer plate material 3 and the upper layer plate material 4 can be efficiently transferred by adjusting the timing of loading and transfer, and the wood-based building. Materials 1,100 can be manufactured in a short time.

また、下層板材２と上層板材４が第一投入手段１１から投入され、中層板材３が第二投入手段２１から投入されるため、これら各板材２，３，４は別々に移送されることになり、積載作業領域Ａに移送されて下層板材２と中層板材３と上層板材４が重ねられるまでに接着剤と硬化促進剤とが接触しないようにすることができる。
また、下層板材２と上層板材４が同じ第一投入手段１１から投入されるため、下層板材２専用の投入手段と上層板材４専用の投入手段を別個に用意する必要が無い。これにより、装置Ｌの大型化を防ぐことができるとともにコストの低減を図ることができる。 Further, since the lower plate material 2 and the upper plate material 4 are input from the first input means 11 and the middle layer plate material 3 is input from the second input means 21, these plate materials 2, 3 and 4 are transferred separately. Therefore, it is possible to prevent the adhesive and the curing accelerator from coming into contact with each other until the lower plate material 2, the middle layer plate material 3, and the upper layer plate material 4 are overlapped with each other by being transferred to the loading work area A.
Further, since the lower plate material 2 and the upper plate material 4 are input from the same first charging means 11, it is not necessary to separately prepare the charging means dedicated to the lower plate material 2 and the charging means dedicated to the upper plate material 4. As a result, it is possible to prevent the device L from becoming large in size and to reduce the cost.

下層板材２と上層板材４には同じ繊維方向の材料用板２ａ，４ａが使用され、中層板材３には、下層板材２および上層板材４と交差する繊維方向の材料用板３ａが使用されているので、積載作業領域Ａでこれらの材料を重ねてプレス作業部１３でプレス作業を行うだけで、繊維直交タイプの木質系建築材料１，１００を容易に製造することができる。 The material plates 2a and 4a in the same fiber direction are used for the lower plate material 2 and the upper plate material 4, and the material plates 3a in the fiber direction intersecting the lower plate material 2 and the upper plate material 4 are used for the middle layer plate material 3. Therefore, the fiber orthogonal type wood-based building materials 1, 100 can be easily manufactured only by stacking these materials in the loading work area A and performing the pressing work in the pressing work unit 13.

また、メイン移送部１０が、下層板材２と中層板材３と上層板材４が互いに重ねられて貼り合わされてなる木質系建築材料１を、下層板材２の代わりに当該メイン移送部１０に対して投入する第三投入手段１５を有するので、この第三投入手段１５から投入された木質系建築材料の上に中層板材３と上層板材４を重ねて接着することができる。これにより、板材が三層を超えて積層する木質系建築材料１００を製造することができる。 Further, the main transfer unit 10 inputs the wood-based building material 1 in which the lower layer plate material 2, the middle layer plate material 3, and the upper layer plate material 4 are overlapped and bonded to each other to the main transfer unit 10 instead of the lower layer plate material 2. Since the third input means 15 is provided, the middle layer plate material 3 and the upper layer plate material 4 can be overlapped and adhered on the wood-based building material input from the third input means 15. As a result, it is possible to manufacture the wood-based building material 100 in which the plate materials are laminated in more than three layers.
