DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a property that when a plate material, especially a pine material or the like is dried, the plate material is twisted in a certain direction. Further, the plate material has a property of warping into a cup shape. This phenomenon is unlikely to occur with raw materials, but always occurs when the material is dried. The present invention relates to a method for drying a stacked plate material and a drying apparatus for a stacked plate material that can prevent this phenomenon.

[0002]

2. Description of the Related Art Conventionally, when drying plate materials, the plate materials are stacked in a drying chamber via a bar between the respective plate materials, and a weight is placed on the stacked plate materials so that the weight is prevented from twisting. That existed.

[0003]

However, in the above-mentioned prior art, for example, a stacked plate material is 3 m long.
There is a drawback that the weight itself is pushed up by the whole repulsive force because the pier is piled up at the height of the place.

There is also a means for tightening from the side with a turn buckle or the like. However, since the stacked plate materials have a property of being reduced by drying, it is necessary to perform additional tightening during drying. However, since the inside of the drying chamber cannot enter the drying chamber due to high temperature, very good results cannot be obtained.

[0005] Even if it is forcibly tightened again, the stacked plate materials themselves are twisted in the same direction as a whole, and a good effect cannot be obtained.

The present invention has been made in view of the above circumstances, and provides a method and an apparatus for drying a stacked plate material in which both side surfaces are fastened with wires or the like via pulleys provided on a fastener which fixes the entire stacked plate material to foundation concrete. The purpose is to do so.

[0007]

The present invention employs the following technical means to solve the above-mentioned problems. Claim 1
In the invention described, in the base concrete of the wood drying room, at least the left and right ends according to the length and width of the wood to be dried, and at least two places in front and back,
Fix the fasteners at a total of 4 or more places, and select one of the fasteners.
One end of the wire is fixed to one end, and the other end of the wire is bridged so that the upper and lower plate members are tightened via the pulley provided on each stopper and the pulley provided on the square material placed on the top stage of the plate material A technical means was adopted in which the timber was taken out with a pulling device driven by a motor so that a constant pulling pressure was always applied.

According to the second aspect of the present invention, the base concrete in the wood drying room is stopped at least at both left and right ends and at least two places at the front and back according to the length and width of the wood to be dried. Fix the bracket,
One end of the wire is fixed to any one of the fasteners, and the other end of the wire is connected to a pulley provided on each of the remaining fasteners and a pulley provided on a square member mounted on the uppermost step of the stacked wood. The upper and lower plates were wrapped so as to be tightened and taken out, and a pulling device was provided outside the wood drying chamber so that a constant pulling pressure was always applied.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention relates to a method for directly drying on the ground in the case of drying by the sun, at least on both the left and right ends, and at least two sides, in accordance with the length and width of the wood to be dried.
At least four places, a total of four or more stoppers are provided, one end of the wire is fixed to any one of the stoppers, and the other end of the wire is provided on the pulley provided on each of the remaining stoppers, and on the uppermost step of the plate material. It is pulled out and pulled out via a pulley provided on the placed square lumber so that it is tightened up and down, and the wood is tightened by a tensioning device using a motor as a drive source so that a constant tensile pressure is always applied.

[0010] Alternatively, for the foundation concrete of the wood drying room,
A total of 4 at least on both the left and right sides and at least 2 places before and after according to the length and width of the wood to be dried
At least one fastener is fixed, one end of the wire is fixed to one of the fasteners, and the other end of the wire is placed on a pulley provided on each of the remaining fasteners, and on the top of the stacked wood. This is a drying device for stacked plate materials in which upper and lower plate materials are wound and pulled out via a pulley provided on a rectangular timber to be taken out, and a tensioning device is provided outside a wood drying chamber so that a constant tensile pressure is always applied.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a schematic front view, and FIG. 2 is a schematic side view. As can be understood from FIGS. 1 and 2, dozens of sawing boards 1 each having a thickness of 20 mm to 50 mm and obtained by stacking several tens of sawing boards 1 from wood with a cutting machine are stacked so as to have a height of about 3 m. Are stacked between the ground plates 1 and stacked and dried in the drying chamber.

The metal fasteners 4 are fixed to at least two places at both ends or a plurality of places between both ends while corresponding to the longitudinal length of the ground plates 1 stacked on the foundation concrete 3. The fixed number of the stoppers 4 is appropriately determined according to the length of the ground plate 1 to be dried.

This is provided so as to face the front side and the rear side. Further, a pulley 5 is provided on the stopper 4.

A pressing member in which pulleys 5 are attached to both ends of a square bar so as to be placed on the uppermost stage of the ground plates 1 stacked so as to face the stoppers 4 provided in front of and behind the stacked ground plates 1. 6 is provided. One of the right and left sides of the front side or the rear side is selected from among the fasteners 4 fixed to the foundation concrete 3, and the wire 7 is fixed to the fasteners 4. The wire 7 is raised upward and wrapped around the pulley 5 provided on the pressing member 6, and further to the pulley 5 of the stopper 4 fixed to the next (the left stopper in this embodiment) the foundation concrete 3. The grinding plate is reduced by the degree of drying by a driving source provided outside the drying chamber, for example, a pulling device 8 by a motor, which is capable of applying a tensile pressure to the end of the wire 7 that has been wound. In response to the above, the tension is always exerted at a constant pressure by the sensor, and the tension is applied by the tensioning device 8 so that both sides are tightened, so that the drying is completed with the ground plate 1 in a horizontal state. is there.

The tensioning device 8 has a structure in which a wire 7 for tightening both side surfaces is provided one by one on each side surface so as to maintain the horizontal state more accurately.
However, it is needless to say that both sides can be tightened by one unit as described above.

In the above description, the fastener 4 is fixed to the foundation concrete 3, but it is sufficient to fix it to a solid material corresponding to the foundation concrete 3.

Although the embodiment in which the tensioning device 8 is installed outside the drying chamber has been described, it is possible to automate the tensioning device, detect the tightening force with a sensor, and drive the tensioning device 8 so that the tension is constantly set at a constant pressure. If possible, it is possible in a drying room. In addition, when performing manually, it is necessary to install outside a drying room.

[0018]

According to the present invention, as a result of employing the above configuration,
The following effects can be obtained. (1) It is not necessary to enter the drying chamber and retighten, so that the plate can be dried very easily and efficiently while preventing twisting and warping of the plate.
