DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a press apparatus for pressing wood, which has been softened by heating, into a rectangular column to increase the density.

[0002]

2. Description of the Related Art An enormous amount of thinned wood is discarded without being effectively used. One of the reasons that thinned wood is not used effectively is that the density is low and the strength is not enough.
If the thinnings can be made strong enough, their use will increase significantly. For example, as a two-by-four frame material, thinning material such as cedar is hardly used, and peeler and pine pine are used. However, if the thinned material can be processed to a sufficient strength, it can be used for this kind of application. If thinned wood with low density and insufficient strength can be made high density and sufficient strength, it can be effectively used as high quality wood. Not only thinned wood but also low-density wood is not used effectively because its use is limited due to lack of sufficient strength.

[0003] By pressing wood while it is being heated, low density wood can be densified and processed to be tough. Wood has annual rings consisting of summer and winter eyes. When wood is heated and compressed, the soft summer eyes are thinly crushed and strengthened. In winter, hard parts have sufficient strength. Natsume is weaker than winter. If Natsume is pressed densely and hardened, the whole wood becomes stronger. Wood can be pressed to high density by heating lignin or hemicellulose, which is the main component, to a temperature higher than the glass transition temperature to bring it into a wet state. The glass transition temperature of wood is 1 when dry
30 ° C to 250 ° C, but 80 ° C to 250 ° C in a wet state.
° C. When the wood is heated in a wet state, the glass transition temperature is lowered, and the wood is easily compressed.

[0004] In order to heat wood to a temperature higher than the glass transition temperature and compress it, an apparatus has been developed in which the wood is pressed into a narrow passage and heated (Japanese Patent Publication No. 2-3646). The device described in this publication presses wood into a narrow passage. The passages are irradiated with microwaves to heat the wood pressed into it.

[0005]

This apparatus can press wood into a narrow passage and compress it. However, devices of this construction have the disadvantage that it is difficult to press the wood hard in the radial direction. This is because the more the wood is pressed in the radial direction, the narrower the passage becomes, and the more difficult it is to press the wood into the passage. Wood pressed into a narrow passage has a high surface pressure against which the wood presses the passage, and increases frictional resistance. The friction resistance between the wood and the passage is
The wood increases in proportion to the surface pressure pressing the passage.

In order to prevent the adverse effects of this structure, the present inventor has developed a press device having the structure shown in FIG. This apparatus comprises a plate 1 bent in an L shape, a horizontal plate 2 for pressing wood on the plate 1 in a horizontal direction, and a vertical plate 3 for pressing wood from the plate 1 from above. Prepare. A plurality of cylinders 4 are connected to the horizontal plate 2 and the vertical plate 3. This apparatus can compress the wood supplied to the plate 1 by pressing it with the horizontal plate 2 and the vertical plate 3.

[0007] The press device of this structure can press four surfaces of wood with a strong pressing force. However, in the device of this structure, a gap is formed between the horizontal plate 2 and the vertical plate 3 as shown in FIG. 2 before the wood is completely compressed, from which the wood protrudes, and the protruded wood is thereafter removed. Has the disadvantage of being easily damaged. When the vertical plate 3 is pressed first and then the horizontal plate 2 is pressed as shown in FIG. 3 in order to prevent this adverse effect, there is a disadvantage that the wood cannot be pressed uniformly from the entire circumference. Further, in the press device having this structure, it is necessary to adjust the width of the horizontal plate 2 according to the width of the wood to be compressed. When the wood to be compressed becomes thicker, the width of the horizontal plate 2 needs to be changed.

Further, it is difficult to press the entire surface of a long piece of wood with a strong pressure by using a press apparatus having this structure. For example, a 10 cm square wood surface with a total length of 2 m
An apparatus for pressing at a pressure of kg / cm ² has a very high press pressure of 40 tons. This requires the use of very large cylinders, and the overall equipment is considerably large, increasing equipment costs. Further, it is very difficult to press the entire surface of the wood uniformly with a long press plate.

[0009] The present invention has been developed with the aim of further solving this drawback. An important object of the present invention is to provide a wood pressing apparatus capable of pressing wood having different thicknesses uniformly from the entire circumference. Another important object of the present invention is to provide a wood pressing apparatus which can uniformly press the entire surface of long wood with a strong pressure and can make the entire apparatus compact. Still another object of the present invention is to provide a press machine for wood which can press wood of various lengths and can be easily mass-produced at low cost.

The hot plate 15 is disposed in close contact with the surface of each press plate. That is, from the first press plate to the fourth press plate
Up to the press plate, four hot plates 15 are respectively arranged at right angles to the adjacent hot plates 15. The square space formed by these four hot plates 15 is an insertion portion for the wood to be pressed.

Further, the hot plate 15 has a length equal to the entire length of the press device in which the plurality of press units U are connected. That is, the hot plate 15 is extended so that the back surface thereof is in contact with the surface of the adjacent press plate, and connects the press plates of a plurality of press units connected linearly.
The four hot plates 15 arranged in this state come into contact with the wood with the surface of the hot plate 15 covering the four sides of the pressed wood. Therefore, the wood is pressed to the press plate from four directions with the opposing side surfaces sandwiched by the hot plate 15. The press device that presses the entire circumference of the wood via the hot plate 15 eliminates a step at the joint of the press unit U, and can process the surface of the wood into a flat straight line.

It is on the pressed surface of wood and is connected to a high frequency power supply 11. The press device having this structure has a feature that it can press a preheated or unheated wood by heating. The preheated wood is cooled somewhat before being set in the press. A press device capable of high-frequency heating of wood with a press plate can efficiently press the wood by reheating even if the wood is slightly cooled before setting. Furthermore, after setting and heating wood that is not heated at all, it can be pressed.

A press device in which a plurality of press units U are connected linearly in series with each other presses wood to make it tough as follows. Logs are processed into prismatic or cylindrical shapes. Wood processed into a prismatic shape is pressed on four sides to become high-density wood. The timber processed into a column shape is pressed from four directions and formed into a prism shape. The method of cutting a log into a cylindrical shape and processing it into a prismatic shape with a press device has a feature that the waste amount of the log is reduced and the log can be effectively used. When processing raw wood into a prismatic or cylindrical shape and pressing it,
In a pressed state, it is processed to a thickness having a predetermined size.

Further, it is also possible to press the raw wood into a prismatic shape by a pressing device without cutting. Wood obtained by pressing raw wood into a prismatic shape without cutting can be used as a decorative material for floor pillars or the like because the surface becomes a natural wood surface.
When processing a log into a prismatic shape, the bark is removed or pressed without removing the bark. When the skin is removed and pressed, the surface can be made smooth. Pressing without removing the skin, and removing the skin after the pressing, can produce a natural uneven wood surface.

Wood is autoclaved (not shown)
And steam is injected into the autoclave chamber to heat the wood. The internal temperature of the autoclave chamber is, for example, 80
C. to 200C, preferably 80C to 180C, optimally 1C.
Set to 30-180 ° C. In order to heat wood at a set temperature of 100 ° C. or less, an autoclave chamber is not necessarily required. This is because heating can be performed without applying pressure.
When a press that uses high-frequency heating of the set wood is used, the heating temperature of the wood in this step can be reduced. The heating step can be omitted, and unheated wood can be set in the press device.

The time for heating the wood in the autoclave chamber is set to a time for sufficiently heating the central portion of the wood. Thick wood can be put in the autoclave for a long time, and thin wood can be heated in a short time. For example, 10 cm square wood is heated in an autoclave chamber for several hours.

The wood heated in the autoclave chamber is quickly set on the press so as not to cool.
When setting the wood, the press device shrinks the cylinder to keep the press plates wide open. Between the press plates, a piece of wood processed into a cylindrical or prismatic shape or unprocessed wood is inserted.

The apparatus having the high-frequency power supply 11 heats the wood again by high-frequency waves while the wood is lightly pressed by the press plate. The heating temperature of the wood is 130 to 250 ° C. When the wood is heated to the set temperature, it can be used vertically or in a state where high frequency is not applied.
Wood is pressed by four horizontal cylinders 7 and 6 from four directions and compressed. The compressed wood is squashed and stiffened from the soft Natsume part. The wood is cooled while being kept in the pressed state. After cooling, the rods of the vertical and horizontal cylinders 7 and 6 are contracted to release the press plate, and the wood is taken out.

Further, the wood pressing apparatus of the present invention has features that the whole surface of long wood can be pressed uniformly and with a high pressure, and that the whole apparatus can be made compact. This is because the wood press apparatus of the present invention is divided into a plurality of press units, and the divided plurality of press units are linearly connected in series adjacent to each other. A press device in which a plurality of press units are connected can press a long piece of wood by increasing the overall length of the device. Further, one divided press unit has a reduced area of wood to be pressed, and can be designed to have a lower maximum pressure. For this reason, the pressing pressure of one press unit can be reduced, and the entire surface of long wood can be pressed with a strong pressure. In addition, the press device having this structure does not require the use of a very large cylinder, so that the entire device can be made compact and the equipment cost can be reduced.

Further, the wood press apparatus of the present invention, in which a plurality of press units are connected, has the feature that wood of various lengths can be pressed. This is because the press unit of the present invention can adjust the number of units to be connected according to the length of wood to be pressed. A device that presses long wood increases the number of connected press units, and a device that presses short wood reduces the number of connected press units. In this way, the wood pressing apparatus of the present invention can press wood of various lengths in an ideal state. Moreover, this press device has a feature that it can be easily and inexpensively mass-produced.

Further, the wood press apparatus of the present invention, which connects a plurality of press units, can
Only the failed unit can be replaced with a normal unit. For this reason, there is an advantage that a failed part can be repaired without stopping the production line.
