  Examples of the adhesive include urea resin-based adhesives, phenol-based adhesives, honeymoon adhesives, and other adhesives used for bonding wood materials. A honeymoon adhesive consists of two types of adhesive constituent materials applied to the mutually opposing surfaces of adjacent plate-like members 60. For example, an imide resin is used as the adhesive constituent material, a glyoxal is used as the adhesive constituent material, or a polymer compound having an acetoacetyl group is used as the adhesive constituent material, and an aldehyde compound or polyethyleneimine is used as the adhesive constituent material. Or what has a hydrazine compound as a main component may be used. In short, the specific type of the adhesive is not particularly limited as long as it is an adhesive that rapidly gels or hardens when superposed on each other. Furthermore, in order to improve water resistance and heat resistance, a curing agent that reacts with the adhesive constituent material may be mixed and used in advance.

The plate-like member 60 is obtained, for example, by cutting a rough material stored in a rough material storage area into a predetermined size and then cutting the top surface, the bottom surface, and the left and right side surfaces of the cut rough material. The plate-like member 60 measures the Young's modulus and is classified according to the result.
Then, the plate member of a predetermined grade is conveyed to an adhesive application device, and the adhesive is applied to the upper and lower surfaces of the plate member by this adhesive application device.

Here, when a general adhesive such as urea resin is used as the adhesive, the adhesive is applied only to the middle part of the laminated material 50 and the upper surface of the plate-like member 60 arranged at the lowest level. By overlapping the adjacent members 60, the adhesive is evenly spread on the upper and lower surfaces facing each other. On the other hand, when a honeymoon adhesive is used as the adhesive, one adhesive constituent material is applied to the upper surface 60a of the middle member of the laminated material 50 and the plate-like member 60 arranged at the lowest level, and the assembled The other adhesive constituent material is applied to the lower surface 60b of the member 60 arranged at the uppermost stage and the middle part of the material 50.

Further, as shown in FIG. 2, the laminated material pressing device includes a gate-shaped frame 11. A plurality of frames 11 are provided at predetermined intervals in the longitudinal direction of the laminated material 50 (the direction orthogonal to the paper surface in FIG. 2), and the aligning means 12 is provided in the horizontal portion of each frame 11. This aligning means 12 presses the laminated material 50 carried between the pressing means 1 and the receiving part 2 from above, and the side end surfaces of the plate-like members 60a constituting the laminated material 50 are substantially flush with each other. A pair of guide rods 13 and 13 supported on the horizontal portion of the frame 11 so as to be movable up and down, and fixed to the lower ends of the guide rods 13 and 13 so as to be bridged between the guide rods 13 and 13. The pressing bar 14 is provided. The lower surface of the pressing bar 14 is formed in a smooth horizontal plane.
Further, four hydraulic cylinder devices 15 are fixed to the lower surface of the horizontal portion of the frame 11 with their piston rods facing downward and parallel to each other at a predetermined interval. The lower ends of the piston rods of these cylinder devices 15 are connected to the pressing bar 14. Further, the lower end of the stopper bars 16, 16 is connected to the pressing bar 14. The stopper rods 16 and 16 penetrate the horizontal portion of the frame 11, and stopper members 16a and 16a are attached to the upper end portions thereof. The stopper members 16a and 16a abut against the horizontal surface of the frame 11 when the pressing bar 14 is unexpectedly dropped to prevent the stopper bars 16 and 16 from coming out, thereby preventing the pressing bar 14 from dropping further. It is like that.

  In the aligning means 12 as described above, the piston rod of the cylinder device 15 extends when the assembled material 50 carried between the pressing means 1 and the receiving portion 2 is supported by the support portion 10 from below. As a result, the pressing bar 14 descends and the laminated member 50 is pressed from above with the lower surface of the pressing bar 14 so that the side end surfaces of the plate-like members 60 constituting the laminated member 50 are substantially flush with each other. ing.

Next, the operation of the laminated material pressing device configured as described above will be described.
First, as shown in FIG. 3A, the laminated material 50 is carried between the pressing portion 6 and the receiving portion 2. That is, the laminated material 50 is carried in the direction orthogonal to the paper surface in FIG. 3 by the rotation of the conveying roller 3a constituting the conveying means 3. In addition, before the laminated material 50 is carried in, since the conveyance roller 3a raises and protrudes from the upper surface of the support plate 10a of the support part 10, the laminated material 50 is carried in smoothly by the conveyance roller 3a.

Next, as shown in FIG. 3B, the conveying roller 3 a descends and sinks from the upper surface of the support plate 10 a, so that the laminated material 50 comes into contact with the upper surface of the support plate 10 a and is supported by the support unit 10 from below. Supported.
Next, as shown in FIG. 3C, when the piston rod of the cylinder device 5 of the pressing means 1 is extended, the pressing portion 6 presses one side surface 50a of the laminated material 50 from the lateral direction. Then, the laminated material 50 moves toward the receiving portion 2, and the other side surface 50 b of the laminated material 50 comes into contact with the contact surface 2 a of the receiving portion 2. Thereby, the laminated material 50 is lightly pressed by the pressing portion 6 and temporarily fixed to the receiving portion 2.
In this case, as shown in FIG. 4A, among the ten cylinder devices 5, a total of four cylinder devices 5a, that is, two cylinders 5a at the center and one cylinder device 5a inside both sides. When each of the piston rods expands, the pressing portion 6 is pressed and moved. In addition, since the front-end | tip part of the piston rod of these four cylinder apparatuses 5a is connected with the press part 6, if the piston rod of at least one cylinder apparatus 5a is extended, the piston rod of the other cylinder apparatus 5a will press. It is stretched by being pulled by the part.

  Next, as shown in FIG. 3 (d), when the piston rod of the cylinder device 15 of the aligning means 12 is extended, the pressing bar 14 is lowered to press the laminated material 50 from above, and this laminated material. The side end surfaces on the upper side of the plate-like members constituting 50 are substantially flush.

  Next, as shown in FIG. 4 (b), the piston rods of the remaining six cylinder devices 5 are extended to press the pressing portions 6, so that the pressing portions 6 of the four cylinder devices 5a are moved. The laminated material 50 is pressed by pressing together with the piston rod. That is, by pressing the pressing portion 6 with the piston rods of all the cylinder devices 5 constituting the pressing means 1, the laminated material 50 is finally clamped.

When the main pressing is completed as described above, the piston rod of the cylinder device 15 of the aligning means 12 is contracted to raise the pressing bar 14 away from the laminated material 50, and then the cylinder device of the pressing means 1. By reducing the piston rod 5, the pressing portion 6 is moved away from the laminated material 50.
Next, the conveying roller 3a moves up and protrudes from the upper surface of the support plate 10a, thereby supporting the laminated material 50 by the conveying roller 3a. Thereafter, the conveying roller 3a rotates to carry out the laminated material 50. .
By repeatedly performing the above steps, the laminated material 50 is successively carried in, pressed, and carried out.

As described above, according to the present embodiment, after the laminated material 50 is carried between the pressing portion 6 and the receiving portion 2 by the conveying roller 3a, one side surface 50a of the laminated material 50 is laterally moved by the pressing portion 6. By pressing from the direction and receiving the other side surface 50 b by the receiving portion 2, the laminated material 50 can be pressed in the lateral direction.
Therefore, no pressing force is applied to the conveying means (conveying roller 3a) 3 for conveying the laminated material 50 from the pressing portion 6 of the pressing means 1.
Therefore, it is not necessary to form the conveying means itself firmly or provide a pressure-resistant member as in the prior art, the cost can be reduced, and the conveying means 3 is less likely to fail.

Further, since the laminated member 50 is pressed from above by the pressing bar 14 of the aligning means 12 and the side end surfaces of the plate members constituting the laminated member 50 are substantially flush with each other, the plate members are accurately stacked. Can be glued.
Further, when the laminated member 50 is pressed from above by the pressing bar 14 of the aligning means 12 and the side end surfaces of the plate-like members constituting the laminated member 50 are substantially flush, the conveying roller 3a of the conveying means 3 By sunk from the upper surface of the support plate 10a of the support portion 10, the lower surface of the laminated material 50 is supported by the support plate 10a, so that the pressing force does not act on the conveying roller 3a of the conveying means 3 by the pressing bar 14. Therefore, it is difficult for the conveyance means 3 to fail.

In addition, when pressing the laminated material 50, the piston rod of the cylinder device 5 is extended and the pressing portion 6 presses one side surface 50a of the laminated material 50, so that the pressing force of the laminated material 50 can be easily increased. In addition to being able to adjust, the side surfaces 50a of the laminated material 50 can be pressed by extending the required number of piston rods of the cylinder device 5 according to the length of the laminated material 50.
In this case, for example, a frame or the like of the laminated material pressing device is provided with a sensor facing each of the plurality of cylinder devices 5, and by detecting the laminated material by this sensor, the length of the laminated material is detected, Control may be made so as to select the cylinder device 5 to be operated based on this.
Moreover, since the side surface 50a of the laminated material 50 is pressed by the pressing part 6, the side surface 50a can be pressed uniformly.

Since the piston rods of some (four) cylinder devices 5a are extended and the pressing portion 6 is pressed and moved, the laminated material 50 is brought into contact with the receiving portion 2, so that the piston rods of all the cylinder devices 5 are extended. Compared to the case, the pressing part 6 moves smoothly. That is, when the piston rods of all the cylinder devices 5 are extended, if the extension speeds of the piston rods are slightly different, squeezing is likely to occur when the pressing portion 6 moves, but the piston rods of some cylinder devices 5a In the case where the pressing portion 6 is stretched, the pressing portion 6 can be moved smoothly because the pressing portion 6 hardly moves.
Then, the piston rods of the remaining six other cylinder devices 5 extend and press the pressing portion 6 together with the piston rods of the four cylinder devices 5 to securely press the laminated material 50 in a balanced manner. Can do.

  In the present embodiment, the case where one laminated member 50 is pressed has been described. However, the laminated member pressing apparatus according to the present invention can be applied even when a plurality of laminated members are pressed simultaneously. In this case, what is necessary is just to carry in several laminated | stacked material continuously in a row between the press part 6 and the receiving part 2 of the press means 1. FIG.
