SUMMARY OF THE INVENTION The above-mentioned conventional putty repairing machine for this kind of plate material is a wedge member made of metal, wood or the like, which is elastically fitted in a wedge-shaped gap formed on both sides of the plate material and the knife coater. The contact was made to prevent the putty agent staying in the gap from leaking from both sides, but the surface of the wedge member was gradually solidified by the time change of the putty agent or mixed with wood powder. The admixture cumulatively adheres and solidifies, generating a remarkably excessive frictional force on both sides of the plate during the pressing process,
Therefore, in the process of pushing the plate material from the rear by the pushing roller or the pushing conveyor, the strong braking action on both sides and the swiveling action of the tip end make the pushing action extremely unsmooth, and the both side faces of the plate are also greatly enlarged. Not only will it be damaged, but it will also lose the ability of the wedge member to prevent the staying putty agent from leaking out, and a large amount of putty agent will adhere to both sides of the plate material. This is a serious drawback in that it requires a complicated maintenance work such as artificially removing solid substances or admixtures adhering to the wedge members and solidifying the wedge members, or renewing them.

Therefore, the present invention suppresses the formation of a solid matter or a mixture with wood flour due to the change with time of the putty agent with respect to this kind of wedge member, and naturally, such a thing is subjected to the process of pushing the plate material. In order to discharge it to the outside of the machine, by applying a release agent such as water to both sides of the pre-loaded plate material, the putty agent and wood powder adhering to the wedge member are removed to the outside of the machine, thereby removing the plate material. The purpose of the present invention is to contribute to the improvement of process efficiency and the improvement of product quality and product yield by realizing smooth pushing operation and simplification of maintenance work of wedge members.

[0005]

In order to achieve the above-mentioned object, the method of the present invention is to apply a putty agent to a plate material such as plywood with a knife coater to iron and repair the cracks on the plate surface and the recesses such as insect holes. In a putty repairing machine for plate materials to be used, (a) apply a releasing agent such as pre-water to both side surfaces of a plate material such as plywood that is carried in with the carrying direction aligned by a carry-in conveyor and a ruler roll. b) A method of preventing the putty agent from leaking and adhering, wherein the putty agent and the wood powder that leaks and adheres to both side surfaces of the plate material are separated from the machine.

Further, the apparatus invention of the present invention is a plate material putty repairing machine for ironing a plate material such as plywood with a knife coater to fill and repair cracks in the plate surface and recesses such as insect holes. A roll for applying a release agent such as water disposed between rows of ruler rolls standing on both sides of the carry-in conveyor;
(D) A releasing agent impregnating member such as felt attached to the outer periphery of the coating roll, and (e) a releasing agent dropping means for dropping a releasing agent such as water onto the releasing agent impregnating member. This is a device to prevent the putty agent from leaking and adhering in the putty repair machine.

[0007]

According to the method for preventing the putty agent from leaking and adhering in the plate putty repairing machine of the present invention, the carry-in conveyor and the ruler roll are used to preliminarily carry the carry-in conveyor to both side surfaces of the plywood and the like to be carried in in the carrying direction. By applying a release agent such as water to both side surfaces of the plate material in the process, the putty agent and the wood powder that leaks and adheres to both side surfaces of the plate material can be removed from the machine.

In general, a putty agent of this type for filling and repairing is a type of putty agent that is modified and solidified with time and is made of a foaming resin or the like. Gradually solidifies, and wood powder adhering to both sides of the plate material is also mixed in the process to cumulatively generate solids and admixtures on the surface of the wedge member, and both side surfaces of the plate material in the pressing process. In this process, excessively large frictional force is generated, and in the process of pushing the plate material from the rear by a pushing roll or pushing conveyor, strong braking action on both sides and swiveling action at the tip end make the pushing action extremely unsmooth. Moreover, not only the both side surfaces of the plate material are greatly damaged, but also the leakage preventing function of the putty agent by the wedge member is completely lost and a large amount of the putty agent adheres to both side surfaces of the plate material. Ah .

Therefore, according to the present invention, the adhesive force of putty agent and wood powder which are to be attached to the wedge member for preventing the leakage of the retained putty agent is weakened to be washed away to some extent, and its solidification over time is suppressed. Also, by cooling frictional heat of the putty agent generated in the process of ironing, it is possible to suppress the generation of solid matter or admixture in which at least the putty agent and the wood powder to be attached to the wedge member have changed over time. At the same time, a release agent consisting of water or an appropriate solution, which functions to naturally discharge these things out of the machine in the process of pushing in, is applied to both side surfaces of the plate material in the process of carrying in, a roll, a spray, etc. By applying it beforehand, the putty material and wood powder that adheres to the wedge member are removed from the machine, which facilitates the pushing operation of the plate material and simplifies the maintenance work of the wedge member. It was done.
