However, Patent Documents 1 and 2 disclose a manufacturing method for immersing wood in a chemical solution such as boric acid for treatment, and do not disclose anything about the treatment apparatus.
On the other hand, as a method of injecting a chemical solution into wood, Patent Document 3 may be able to efficiently inject the chemical solution into wood, but this requires various control devices and drive devices such as a pressure resistant container, and their equipment. There is a problem that the cost is high, and particularly when processing long timber such as long wooden pillars, the pressure-resistant container and the like become large-scale and the manufacturing cost becomes high.

Therefore, in order to reduce the equipment cost and the manufacturing cost, a method of simply immersing the wood in a treatment tank containing a chemical solution and treating the wood is generally performed.
In this dipping treatment, when wood is put into the chemical solution in the treatment tank, the wood floats due to buoyancy, a part of the wood floats from the liquid surface, and the entire wood cannot be immersed in the chemical solution, so that the wood is immersed in the wood. The chemical solution was not uniformly impregnated, and defective products were generated.
As a countermeasure, heavy wood or heavy stones made of concrete or iron were placed on the wood to prevent the wood from rising.
However, with these woods and heavy stones, it takes time to put them on, and even if they are removed, they are forced to do manual work because they are immersed in a chemical solution, and in any case, the use of heavy stones has a problem of poor workability. there were.

According to the present invention, the treatment device is inexpensive, and when a large number of bundled woods are immersed in a chemical solution, the entire wood can be easily immersed in the chemical solution, and the workability is good.
