[Surface material positioning process]

The frame 3 having the adhesive applied to the upper surface is transported on the gantry 12A by the belt-type conveyor 12B of the frame holding mechanism 12. At this time, the photoelectric tube detects the frame 3 and the frame 3 is placed on the belt conveyor. Is detected,
The base portion 12E of the lengthwise movable ruler 12D is raised, and the holding plate portion 12o is set in a state of protruding above the upper surface of the gantry 12A. As a result, the end surface of the framework 3 is held during the conveyance. At this position, the framework 3 is locked. When the framework 3 is locked by the holding plate portion 12o, the belt-type conveyor 12B stops, and the widthwise and lengthwise movable rulers 12B are stopped.
The holding plates 12h and 12o of C and 12D move so as to approach each other. That is, when the framework 3 is locked by the holding plate portion 12o, the hydraulic motors M1 and M2 of the widthwise and lengthwise movable rulers 12C and 12D respectively rotate, and the screw shafts 12j, 12q and 12r are respectively rotated. The sliders 12i, 12p screwed onto these screw shafts 12j, 12q, 12r are screwed into the holding plate portions 12h, 12o.

It is set at a position facing the face plate 5 held by the holding mechanism 13. When the press platen 14 moves to the upper surface of the face plate 5, the upper plate portion 13w of the work table 13a on which the face plate 5 is mounted rises, and the face plate is pressed between the press platen 14 by pressurization of the hydraulic cylinder 21. Fix the bend and pinch the piping of press platen 14.
The face plate 5 is attracted to the lower surface of the press platen 14 by the suction force from 14c. At this time (when the face plate 5 is sucked by the press platen 14), the face plate 5 is securely positioned on the work table 13a of the positioning device 13 by the suction force of the vacuum pump.
The work table 13a is accurately placed on the lower surface of the press platen 14 without the face plate 5 being displaced and being attracted to the press platen 14.
The upper face plate 5 can be held. The press platen 14 having the face plate 5 adsorbed on the lower surface is raised and moved to a position facing the upper surface of the framework 3 with the movement of the frame 40. Then, at a position facing the framework 3, the press platen 14 descends, adheres the face plate 5 to the upper surface of the framework 3, and presses the face plate 5 from the upper surface by the hydraulic cylinder 22. At this time (at the time of pressing with the press platen 14), the framework 3 is pressed by the press platen 14 onto the frame 3 because the periphery thereof is pressed by the widthwise and lengthwise movable rulers 12C and 12D. Also, the frame 3 does not collapse, and the frame 3 and the face plate 5 are accurately bonded. The press pressure of the press platen 14 is controlled by a pressure transmitter 60 in the hydraulic circuit, and a press pressure according to the size of the framework 3 is applied between the framework 3 and the face plate 5. When the step of bonding the face plate 5 and the frame 3 by the press platen 14 is completed, the pressing by the widthwise and lengthwise movable rulers 12C and 12D is released, and the holding plate portion 12o of the lengthwise movable ruler 12D is returned to the original position. , The base 12E is lowered, and the belt-type conveyor 12B is operated to move the frame 3 on which the face plate 5 is stuck.
Is transported. When attaching face plates to both sides of the framework, an adhesive is applied to the other side of the framework 3 after the reversing step by the reversing mechanism, and the framework holding mechanism 12, the positioning device 13, the press platen 14,
The face plate 5 is pasted again by the action of the above, and the wooden panel is completed. Thus, in the wooden panel manufacturing apparatus having the face plate positioning device having the above-described configuration, the face plate 5 can be accurately set at a position corresponding to the positioning position of the framework. Since the frame 3 can be securely held by the two movable rulers 12C and 12D provided, the face plate and the frame can be accurately bonded and pressed using the press platen 14, and as a result, the panel manufacturing line Can be mechanized, and its workability can be improved. At the time of pressing the face plate and the framework, the framework constituted by the framework working table is held by the two movable rulers of the framework holding mechanism so as to clamp the frame from around the frame, and is held by the framework holding mechanism. Since the face plate 5 is pressed and bonded from the upper surface of the frame 3 by the press platen 14, the stapling work between the frame 3 and the face plate 5 can be omitted completely, and the workability can be improved. There is also an advantage that you can do. Further, in the embodiment, when the face plate 5 is attracted to the lower surface of the press platen 14, the upper plate portion 13w of the work table 13a on which the face plate 5 is mounted rises. Since the bending is corrected by sandwiching the face plate between the press platen 14, the bonding surface between the face plate 5 and the frame 3 can be made flat, and the assembling accuracy of the face plate 5 and the frame 3 can be improved. There is an effect that can be. Further, when the face plate 5 is attracted to the lower surface of the press platen 14, since the face plate 5 is securely positioned on the work table 13a of the positioning device 13 by the suction force of the vacuum pump,
The work table 13a is accurately placed on the lower surface of the press platen 14 without the face plate 5 being displaced and being attracted to the press platen 14.
There is also an effect that the upper face plate 5 can be held. Control of each mechanism constituting the manufacturing apparatus is performed by a computer, and control of a manufacturing process corresponding to various panels is performed based on information from a card indicating the size of the panel. [Effects of the Invention] As described above, the positioning device for a wooden panel face plate according to the present invention includes a frame body assembled in a square frame shape by a frame material and a reinforcing core material provided inside the frame body. When assembling a face plate large enough to cover one face of the framework on the upper surface of the framework consisting of: a rectangular work table for setting the position of the face plate horizontally, and A plurality of fixing pins which are provided to be able to protrude and retract at one end on the short side of the work table and set the position in the longitudinal direction of the face plate; And a plurality of movable pins that are provided movably in the short direction of the work table and set the position of the face material in the width direction, and that the work table includes Center of A suction tube for fixing the face plate at a position where the face plate is positioned by the suction force of the vacuum pump is opened, and the size of the face plate is set at the other end of the short side on the work table opposite to the fixing pin. Since the phototube for detection is provided, the following excellent effects can be obtained. (A) Since the positions of the face plate to be installed on the work table in the width direction and the length direction are determined by the fixed pins and the movable pins on the work table, the face plate is mounted by touching the edges of the face plate to these pins. Can be reliably and accurately set at a predetermined installation position, and the workability of the work of setting the face plate can be improved. (B) Further, since the face plate set on the work table is reliably positioned at the position by suction by suction from the suction tube, the face plate is displaced even when the face plate placed on the work table is picked up. Without pressing, the face plate set by the positioning device can be accurately pressed on the upper surface of the framework to integrate the framework and the face plate,
Thereby, the work of joining the frame and the face plate can be mechanized, and the workability of panel manufacturing and the quality of the panel can be improved.
