The waste wood pieces 1a cut by the cutting block 120 configured as described above are collected on the upper surface of the frame 110 or are not shown in the drawing but are loaded in a separate storage box, or are transferred to the drying unit 200 by a conveying conveyor. Can be transported.

As shown in Figure 4, the drying unit 200 is arranged in a multi-stage inside the hermetic drying chamber 210, drying chamber 210 drying conveyor 220 for conveying the waste wood piece (1a) cut by the cutting unit 100 The drying chamber 210 is formed in a drying atmosphere, and is configured as a dryer for drying the waste wood pieces 1a transferred along the drying conveyor 220.

The drying conveyor 220 is disposed in multiple stages to transport the waste wood pieces 1a so as to lengthen the drying time while minimizing the area of the drying chamber 210. The inlet of the drying chamber 210 is disposed higher than the outlet so that the waste wood piece 1a is transported in a free-falling manner to the drying conveyor 220 arranged in multiple stages, and the cutting part 100 and the resin mixing part 300 Inlet and outlet are disposed on the opposite side of the drying chamber (210) in consideration of the line with ().

Drying conveyor 220 may be made of a mesh structure so that the waste wood piece (1a) laid on the bottom of the drying conveyor 220 can be quickly dried. Since the waste wood piece 1a is 50 cm or less in length and 9 to 50 mm in thickness, the size of the mesh is formed so that the waste wood piece 1a does not fall out.

The drying unit 200 maintains the interior of the drying chamber 210 at 90 ~ 150 ℃ to adjust the waste wood piece (1a) to a water content of 8%. In the drying method, a method of supplying hot air or irradiating infrared rays may be applied together or only one of them may be selectively applied. Hot air drying method is dried from the surface of the waste wood piece (1a), according to the infrared irradiation method is dried from the inside of the waste wood piece (1a) to shorten the drying time, improve the thermal efficiency and prevent deformation of the waste wood piece (1a) do.

The resin mixing unit 300 is a resin mixing conveyor 310 installed inside the resin mixing chamber 310 and the resin mixing chamber 310 having a space therein, and supplying the waste wood pieces 1a dried by the drying unit 200 ( 320, and a resin injector 330 for injecting a resin (for example, urea resin, melamine resin, phenol resin, urethane resin and isocyanate resin) to the waste wood piece (1a) that is carried on the resin mixing conveyor (320). . The resin may be mixed with 10 to 20% of the total weight of the waste wood piece (1a).

The resin mixing conveyor 320 is preferably a mesh conveyor similar to the drying conveyor 220.

The resin injector 330 receives resin from a resin tank (not shown) and injects the resin into the resin mixing conveyor 320. The resin injector 330 is provided in a plurality of upper and lower portions of the resin mixing conveyor 320. ) Is installed.

Since the waste wood piece 1a is not aligned with the resin mixing conveyor 320 and the resin falls from the waste wood piece 1a, some resin is buried on the surface of the resin mixing conveyor 320, and the resin is mixed with the resin mixing conveyor 320. If solidified in the resin mixture efficiency of the waste wood piece (1a) will be reduced, so that the washing means for washing the resin mixing conveyor 320 may be further provided.

Since the resin is washable by the washing water, the washing means uses the washing water.

The bottom of the resin mixing chamber 310 is provided with a washing tank 340 containing the washing water, the resin mixing conveyor 320 to pass through the washing tank 340. That is, the upper portion of the resin mixing conveyor 320 is arranged in parallel for the transfer of the waste wood piece (1a) and the lower portion is arranged to pass through the washing water of the washing tank (340). The arrangement of the resin mixing conveyor 320 may be variously modified through the arrangement of the pinch roller 321.

The brush 350 is installed on the path of the resin mixing conveyor 320 (eg, inside the cleaning tank 340) so that the resin attached to the resin mixing conveyor 320 can be scraped off by physical force. The brush 350 may be a roller brush or the like.

For reference, since the urea resin is a thermosetting resin, it does not harden until heat is applied, but the waste wood pieces 1a are not bonded to each other even if the waste wood pieces 1a are overlapped in the resin mixing part 300.

6a and 6b, the alignment unit 400 is to align the waste wood piece (1a) in order to continuously produce the plate, the waste wood piece 1a (mixed resin) through the alignment conveyor 410 Feed continuously and align thickness and width to the plate.

Alignment conveyor 410 is made of a width (preferably larger than the plate) to match the width of the plate.

The waste wood piece 1a mixed with the resin in the resin mixing part 300 is introduced into the sorting conveyor 410 and at the same time the thickness (the thickness is greater than the thickness of the finished product because the thickness is before compression) and the width (both left and right sides are not in a straight line). Since it will be irregular, it will be larger than the width of the finished product in consideration of future cutting.

The thickness adjusting unit 420 is similar to the left and right widths of the alignment conveyor 410 and is installed at a predetermined height (thickness) away from the surface of the alignment conveyor 410. The thickness adjuster 420 is fixedly installed to a frame supporting the alignment conveyor 410.

The thickness adjusting unit 420 is made of a flat plate to remove the waste wood piece (1a) of a predetermined height or more from the sorting conveyor 410 of the waste wood piece (1a) carried on the alignment conveyor 410, the thickness of the waste wood piece (1a) Adjust

To this end, the thickness adjusting unit 420 further includes a recovery passage 421 for guiding the waste wood piece 1a removed above the thickness adjusting unit 420 to another place. Recovery path 421 can be any shape that can remove the waste wood piece (1a) removed from the upper side of the thickness adjuster 420 in the alignment conveyor 410, for example, the recovery path 421 is a waste wood piece (1a) It may be formed to be inclined so as to guide the left and right edges from the center of the thickness adjuster 420.

Since the waste wood piece 1a recovered by the recovery passage 421 is not waste, it may be returned to the inlet side of the alignment conveyor 410. The recovery path 421 may be formed to be inclined so that the waste wood pieces 1a sorted upward through the thickness adjusting unit 420 are recovered without passing through the recovery path 421.

The thickness adjusting unit 420 may be formed to be inclined downward toward both left and right sides so as to sort the waste wood pieces 1a without the recovery passage 421.

The width adjusting unit 430 is erected on both sides of the left and right width direction of the alignment conveyor 410 in the form of a plate to remove a portion of the left and right width direction in accordance with the width of the plate of the waste wood piece (1a) is put into the alignment conveyor 410. The width adjusting unit 430 may be formed entirely from the inlet side to the outlet side of the alignment conveyor 410 or may be formed only up to a certain distance from the inlet side.

A recovery path (not shown) is provided to return the waste wood piece 1a removed from the alignment conveyor 410 to the alignment conveyor 410 by the width adjusting unit 430.

In addition, since the bending material of the sheet material having a uniform direction (preferably in the longitudinal direction of the sheet material) of the waste wood piece 1a may have a good bending strength, a plurality of alignment tables 440 may be applied thereto.

The alignment table 440 is fixed to the arrangement 444 along the longitudinal direction on the alignment conveyor 410 so that the waste wood pieces 1a are arranged along the longitudinal direction. That is, the alignment conveyor 410 is rotated to the endless track, but the alignment table 440 is fixed to the installation position so that the waste wood piece (1a) is carried in the alignment conveyor 410 to maintain the longitudinal direction. Specifically, as shown in Figure 6c, the waste wood piece (1a) arranged in the longitudinal direction of the waste wood piece (1a) is carried on the alignment conveyor 410 is conveyed while maintaining the state and does not maintain the longitudinal direction When the inclined or extremely arranged in the width direction while passing through the alignment table 440, the waste wood piece (1a) is converted to the longitudinal direction.

Alignment table 440 is a plate that is longer than the width direction surface in the longitudinal direction is preferably formed in a streamlined front end portion.

The alignment table 440 may be installed to linearly reciprocate forward and backward by the actuator 450 (hydraulic cylinder or the like). The alignment bar 440 is linearly reciprocated in the conveying direction of the waste wood piece 1a, so that the alignment of the waste wood piece 1a is performed efficiently.

As shown in Figure 1, the pressing unit 500 is aligned with the alignment unit 400, the primary processing plate material 1b (the waste wood pieces (1a) is aligned with the plate material by the alignment unit 400) To be processed into a sheet material, and may be divided into a primary pressing part 510, a secondary pressing part 520, and a third pressing part 530.

Since the primary processed plate material 1b is not aligned at all, only the alignment is performed, the primary pressing part 510 is applied with a multi-stage roller press method as shown in FIG. 7.

The primary pressurizing unit 510 passes through a plurality of pressurizing rollers (511, 512, 513) and pressure rollers 511, 512, 513 spaced apart from each other at regular intervals along the transport direction of the primary working plate 1b. It consists of a plurality of press roller blocks 514, 515, 516 (shown as three in the figure) for pressurizing the primary work plate 1b again.

The first to third pressing rollers 511, 512 and 513 sequentially press the primary work plate 1b to be conveyed along the conveying conveyor 517 using two sets arranged up and down, respectively. That is, as the first pressing roller 511 moves from the first pressing roller 513 to the third pressing roller 513, the interval through which the primary processing plate member 1b passes becomes smaller.

The first to third pressing roller blocks 514, 515 and 516 are compressed while transporting the primary workpiece plate 1b by the rotational force of one or more blocks (shown as three in the drawing) arranged up and down, respectively.

Although the primary pressurizing unit 510 compresses the primary processed plate member 1b by physical force, the heat and pressure are simultaneously applied to the press rollers 511, 512, 513 and the press roller blocks 514, 515, 516 by adding a heating wire. You may.

As shown in FIG. 8, the secondary press part 520 is in the form of a continuous roller press by a pressurized conveyor, and compresses the primary processed plate member 1b with heat and pressure in the upper and lower parts.

The primary pressurizing unit 510 of the pressing unit 500 is a pretreatment process for compressing the primary processed plate material 1b to the thickness of the product, and the secondary pressurizing unit 520 is for compressing and adhering to the plate product. can do. Therefore, the pressing force and the heat of the large force must be provided in the secondary pressurizing unit 520. For this purpose, the pressing conveyor 521 disposed up and down is provided with a pressing roller 522 so as to give a large pressing force in all sections. .

The secondary pressurizing unit 520 may supply heat by an electric heating wire or the like, or supply heat of the infrared heater 523.

As shown in FIG. 9, the tertiary pressurizing unit 530 is to further compress the secondary pressurized primary processed plate member 1b to a desired thickness of the plate, and is the same continuous roller press type as the secondary press unit 520.

The tertiary pressurizing part 530 is composed of a pressurizing conveyor 531 arranged up and down and a plurality of pressurizing rollers 532 pressurizing the pressurizing conveyor 531. However, since the primary working plate 1b is almost compressed into the product state through the secondary pressurizing unit 530, in the tertiary pressurizing unit 530, the size of the press roller 532 is equal to that of the secondary pressurizing unit 520. It is formed smaller than the pressure roller 522.

Although not shown in the drawing, since the primary processing plate member 1b may be pushed to the left and right sides when pressurized by the pressing unit 500, the primary processing plate member 1b may not be pushed to the left or right on both sides in the width direction of the pressing unit 500. A supporting plate may be further provided.

As shown in FIG. 10, the plate cutting part 600 is divided into a left and right cutting part 610 that cuts irregular surfaces on both left and right sides, and a length cutting part 620 that is cut to fit the length.

As shown in FIGS. 10A and 10B, the left and right cutting parts 610 cut the left and right sides of the secondary processed plate material 1c (referring to the compressed plate) to be supplied from the tertiary pressurizing part 530. It consists of a pair of cutters 611 spaced apart at regular intervals along the width direction to cut both sides of 1c).

The pair of cutters 611 cuts the left and right sides of the secondary processed plate material 1c conveyed by the feed roller 612 (which may be disposed above and below to support the secondary processed plate material 1c). The left and right sides of the difference processed board member 1c are finished in a straight line.

As illustrated in FIG. 10C, the length cutting part 620 may include a slider for reciprocating along a pair of first guide rails 621 and the first guide rails 621 formed along the conveying direction of the secondary processed plate material 1c. 622, the second guide rail 623 and the second guide rail 623 which are connected to the slider 622 and arranged in a direction (length cutting direction) across the first guide rail 621 are installed to be movable. It consists of the cutter 624 which cut | disconnects the secondary process board | plate material 1c in the longitudinal direction.

The slider 622 and the cutter 624 reciprocate back and forth by driving means (motor and the like), respectively, which are not shown.

The cutter 624 initially waits after the left and right cutting parts 610, and when the cutting position of the secondary workpiece plate 1c reaches the cutter 624, the slider 622 moves along the first guide rail 621. While the cutter 624 moves along the second guide rail 623, the secondary processed plate member 1c is cut to a desired length.

The chuck 625 may be applied so that the secondary processed plate material 1c does not shake when cutting by the cutter 624. The chuck 625 is installed on the slider 622 vertically (in order to support the secondary processed plate material 1c at the upper and lower parts), and at least one of them is elevated to fix the secondary processed plate material 1c.

Alternatively, as shown in FIG. 10D, the cutter 624 may be lifted to cut the secondary processed plate material 1c. Of course, here too, the cutter 624 must reciprocate for a certain period.

The supporting means 720 having such a configuration is mounted on both sides in the width direction of the drying conveyor 710 so as to support both sides of the tertiary processed plate material 1d.

Since the thickness of the fixed block 721 is the insertion space of the tertiary processed plate material 1d, by adjusting the thickness of the fixed block 721, the tertiary processed plate material 1d of various thicknesses can be dried, and thus, the fixed block ( 721 is detachably installed in the drying conveyor (710).

The first and second supports 722 and 723 are each made of a length capable of supporting the tertiary work plate 1d.

The third processed plate member 1d can be dried by inserting the third processed plate member 1d between the first and second support members 722 and 723. However, the third processed plate member 1d may be replaced by the first and second support members 722 and 723. Since the work inserted between the first and second supports (722, 723) is cumbersome and inconvenient, the fixed block (b) through the hinge so that the position in the plate inlet (A) and the plate drying unit (B) and the plate outlet (C) is different ( 721 is rotatably installed.

That is, the plate inlet (A) side is flipped toward the drying conveyor 710 side so that the second support 723 placed on the upper side relatively does not interfere, and the first support 722 lowers the third processed plate 1d. Support from

In the board | plate material drying part B, the 1st, 2nd supporters 722 and 723 stand up and support the 3rd process board material 1d inserted between them.

In the plate outlet part C, the first support 722 is flipped toward the drying conveyor 710 so that the third processed plate material 1d is supported only by the second support 723 disposed on the lower side. In the plate outlet part C, even if the first support 722 is not folded, the third support plate 1d may be withdrawn, and thus the first support 722 may not be folded.

When moving from the plate outlet portion C to the plate inlet portion A side, the first support 722 may be unfolded or flipped.

As shown in FIG. 11B, in the plate inlet portion A, the first actuator 724 is installed so that the second support 723 is folded, and the secondary processing plate 1d is seated on the first support 722. At the point of entry into the drying unit B, a second actuator 725 is installed to extend the second support 723. The first actuator 724 pushes the free end side of the second support 723 and the second actuator 725 pushes and extends the hinge side end of the second support 723.
