2. Description of the Related Art Conventionally, in prefabricated houses made of wood, walls, floors, roofs, etc. have been constructed using wood panels. Figure 22 is an example of a wood panel that can be applied to the construction of such prefabricated houses.
There is a structure as shown in . This wooden panel has reinforcing core materials 2a, 2b extending vertically and horizontally inside a frame 1 assembled in a square frame shape by frame materials (core materials) 1a, 1b forming vertical and horizontal stiles. The inside surrounded by the reinforcing core materials 2a and 2b and the vertical and horizontal frame materials 1a and 1b is filled with a heat insulating material 3 such as glass wool, and on both the front and back of the frame 1, Face materials 4, 4 each made of plywood are attached.

By the way, when manufacturing such a conventional wooden panel, the frame 1 and the vertical and horizontal reinforcing core materials 2a,
In manufacturing the frame 2 consisting of 2b, as a pre-process, the vertical and horizontal frame members 1a and 1b constituting the frame 1 are subjected to phase cut groove processing, and the frame members are assembled by combining the phase cut grooves of the frame members 1a and 1b. 1, and a reinforcing core material 2 is placed inside this frame 1.
A, 2b are assembled in a cross shape etc. to form a framework 2, and this framework 2
A method of pasting plywood (face material) 4, 4 on both sides of the board is used. These manufacturing processes are conventionally shown in Figure 23.
This is carried out by using manufacturing equipment as shown in .

To explain this manufacturing process, first, the frame materials 1a and 1b which have been subjected to the cutout groove processing are placed on a workbench 5 having a horizontal flat plate 5a, and two workers A and B cut the frame materials 1a and 1b. . Attach the reinforcing core materials 2a and 2bb. In addition, each frame material 1
Needless to say, the reinforcing core materials 2a, 2b, etc. are nailed by the hands of workers A and B using an automatic nailer or the like.

[0005] Next, an adhesive is applied to the frame 2, in which the reinforcing core materials 2a and 2b are attached to the frame 1, by an adhesive applicator 7 having an adhesive roller 7a for applying adhesive. Then, on the flat plate 8a of the workbench 8, the facing material 4 is pasted on one side of the framework 2, turned over, sent to the adhesive coating device 7, and passed through the adhesive roller 7a of the adhesive coating device 7, thereby forming the framework. Apply adhesive to the other side of 2.

Next, at the same time as applying this adhesive, the framework 2
A heat insulating material 3 cut into a predetermined size and shape is filled inside the panel, and a panel material 4 is attached from the upper surface of the framework 2 on the flat plate 9a of the workbench 9 to produce a wood panel as shown in FIG. Note that the frame 1, plywood, etc. have larger external dimensions in advance to allow for finishing allowance, and are usually subjected to sizer processing as a post-process after the manufacturing process using the manufacturing apparatus shown in FIG. 23. Care has been taken to ensure that the dimensions are as specified.

[0007] However, there are the following disadvantages in manufacturing the wood panel described above. When fixing the frame 1, each frame material 1a, 1b is placed directly on the workbench, assembled in this state, and then sent to the next process.
Since it is simply assembled using pre-formed phase grooves, there is a risk that the frame will be sent to the next process without ensuring sufficient overall dimensions, squareness, straightness, flatness, etc., resulting in variations. It is somewhat difficult to obtain uniform, high-quality wood panels.

[0008] Furthermore, since the framework work is carried out simply by using the recessed grooves, the worker's intuition is largely relied upon in order to provide the frame 1 with a sufficiently accurate squareness and straightness. Therefore, it requires a high degree of skill on the part of the operator and is time-consuming, so that no improvement in productivity can be expected.

[0009] Therefore, the present applicant filed Japanese Patent Application No. 1-3432.
We proposed a framework for manufacturing wood-based panels as shown in No. 44. The framework frame for manufacturing wood-based panels includes a rectangular fixed frame placed on a jig stand for wood-based panel manufacturing, and a pair of opposing sides of the fixed frame in a state perpendicular to these sides. The first movable bar attached and the second movable bar attached perpendicular to the opposite pair of sides and another pair of sides are respectively perpendicular to the sides to which they are attached. It is configured so that it can be moved while being maintained in the same state. The above problem is solved by framing the frame material along a square frame formed by the fixed frame and the first and second movable bars.

0010

[Problems to be Solved by the Invention] By the way, when manufacturing a wooden panel using the above-mentioned framework frame, after the frame body is assembled within the framework frame, adhesive is applied to the frame body, and adhesive is applied to the frame body. The face plate is attached. However, since the frame body is fixed to the frame, it is not possible to fill the inside of the wooden panel with heat insulating material or attach the face plate to the back of the wooden panel, so the wooden panel must be removed from the frame and reversed. There is a need.

[0011] Therefore, in order to automate the production of wood-based panels, a demolding machine for removing the wood-based panels from the frame is required. In order to automate the production of wood-based panels using framed frames, this demolding machine has a function of removing the frame from the framed frame, a function of sending the removed frame to the next process to invert it, and a function of sending the removed frame to the next process to invert the frame. A function is required to transport the removed framework frame to the framework workbench, which is the first step in the production line.

The present invention has been made in view of the above circumstances, and its purpose is to automatically remove the frame from the frame and remove the frame when manufacturing a wooden panel using the frame. To provide a wood panel demolding machine for a wood panel manufacturing line capable of sending an empty framework frame to the next process and returning it to the first process.

[0013]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a rectangular plate-like work table on which a framework frame is placed, and a wooden panel that is moved from the side onto the work table. A rectangular suction means for suctioning and lifting the suction means, two guide rails for supporting the suction means from both sides and guiding it onto the work table, and a support base for supporting the work table and the guide rails. The front part of the work table is rotatably supported by a support base, and projecting sides projecting left and right from both ends of the rear part of the work table, and the support base includes a support base that extends from the rear of the work table. A locking piece is provided that extends approximately on the circumference, which becomes the trajectory of the protruding piece when the work table rotates, and the protruding piece is provided with a hook piece that extends from above the work table to raise the upper surface of the work table from horizontal. Flexible linear bodies are provided to support the angles of the inclined work surface of the jig stand, and the linear bodies are hooked to the hanging pieces when the work table is in a horizontal state. The book guide rail is supported above the work table in parallel along the moving direction of the suction means at intervals equal to the width of the suction means by support parts extending substantially horizontally from the front and rear parts of the support base, The support part is characterized in that one end thereof supports the guide rail, and the other end is rotatably supported on the support base so as to direct the guide rail upward.

[0014]

[Operation] According to the wood panel demolding machine of the present invention, the frame sent from the face plate press machine, which is the previous process, is placed on the work table. Then, the suction means guided by the guide rail moves above the framework frame on the work table. Then, by suctioning the face plate of the wooden panel fixed to the framework frame, the wooden panel is removed from the framework frame and lifted. Next, the wood panel is moved to the next step along the guide rail with the suction means sucking the wood panel.

After the suction means moves, one side of the working table is lifted by the flexible linear body, and the top surface of the working table is tilted at a predetermined angle. This is because the work surface of the jig stand for fixing the core material to the framework frame is tilted at an angle of approximately 45 degrees to facilitate the work. The work table is tilted to make it easier to return the items. Then, before tilting the work table, the guide rail is raised upward so as not to interfere with the tilting work table.

[0016] Furthermore, when the work table is lowered horizontally, the central part of the flexible linear body is hung on the hook piece so as not to interfere with the suction means that moves while being guided by the guide rail. will be stopped.

As shown in FIG. 9, a plurality of circular holes (
(only one is shown in FIG. 9) 80c is provided, and the suction means 80
At a position corresponding to the hole 80c on the upper surface 80d, an air cylinder device 81 is installed perpendicularly to the upper surface 80d of the suction means 80 with the piston rod 81a facing downward.

Face plate 4 of wooden panel P
It is designed to be able to absorb parts.

Next, a method of manufacturing a wood panel using a wood panel demolding machine in a wood panel production line with such a configuration will be described. First, the framework frame 10 is placed on the work surface of the jig stand 50. This framework is
It was returned from the demolding machine. When the first movable ruler 13 and the second movable ruler 14 are returned, they are moved horizontally or vertically, respectively, according to the dimensions and shape of the frame 1 to be manufactured. The fitting pins 20, 20 are fitted into the holes 17c, 17c at corresponding positions and fixed at the positions.

At this time, the lever 30 of the framework frame 12
with each guide plate 1 lifted upward.
7a, 17b to the first to third link parts 31a, 3
1b and 31c, respectively, so that the first and second movable rulers 13 and 14 are separated from the inner surface of the opposing fixed frame 12 by more than the dimension of the framework 2, that is, the first
And the second movable rulers 13 and 14 are left in a relaxed state. In this case, each of the first movable ruler 13 and the second movable ruler 14 is moved in advance, and these movable rulers 13
(14) and the vertical and horizontal frames 12a, 12b, so the movable ruler 13 (14) and the vertical and horizontal frames 12a, 12b when the movable ruler 13 (14) returns to their normal positions are Even if the spacing between the levers 30 and 30 matches the desired dimensions of the framework 2 with great precision, the lever 30
Since there is enough room for these operations, each frame member 1a (1b) can be placed extremely easily.

Next, a magnetic card on which a code for pushing up the support pins 61 corresponding to the size and shape of the frame 2 to be manufactured is written is inserted into the card reader. This operation causes a plurality of pre-coded support pins 56 to protrude onto the framework frame and push up the leaf spring 15.

Next, the frame members 1a and 1b are placed on the base 11 along the inner surface of the rectangular frame formed by the fixed frame 12 and the first and second movable rulers 13 and 14. At this time, the frame materials 1 and 1b are fixed frame 12
Alternatively, it is arranged between the first and second movable rulers 13, 14 and the pressing plate 15d which is urged by the leaf spring 15 and pushed up by the support pin 56.

[0079] Then, the reinforcing core materials 2a and 2b are installed on the framework frame 10. At this time, the reinforcing core material 2a,
2b is placed between the leaf springs 15 arranged oppositely, that is, between the pressing plates 15d pushed up by the support pins 56.

[0080] When all the frame materials 1a, 1b and reinforcing core materials 2a, 2b have been placed, the lever 30 of the framework frame 10 is pushed down, and the first and second movable rulers 13,
By moving the frame material 14 in the direction of the opposing vertical and horizontal frames 12a and 12b, the frame material 1 placed in the shape of the framework 2 is
, 1b and reinforcing core materials 2a, 2b are pressed from above, below, left and right to regulate the frame 2 into an accurate shape. At this time, the first
The second movable rulers 13 and 14 are linked by first to third link parts 31a, 31b, and 31c.
The book guide plates 17a and 17b are moved in orthogonal directions by moving two book guide plates 17a and 17b in the same direction by operating the lever 30.

[0081] Then, the first and second movable rulers 13,1
4, almost at the same time as the framework 2 is tightened, the pressing plate 15d is tightened.
The support pin 56 that is pushing up is moved downward. Then, by lowering the support pin 61, the pressing plate 15d biased by the leaf spring 15 pushes the frame members 1a, 1b or the reinforcing core members 2a, 2b onto the fixed frame 12 facing the leaf spring 15, the first Then, it is pressed against the second movable rulers 13, 14 and the pressing plate 15d pressed by the other leaf spring 15. Therefore, the frame materials 1a, 1b and the reinforcing core materials 2a,
2b will be fixed to the framework frame 10 in the shape of the framework 2 to be formed.

Furthermore, while the outer periphery of the completed framework 2 is fixed with the framework frame 10, the framework 2 and the framework frame 10 are slid on the work surface 51.
can be sent to the next process in that state. The framework 2 and the framework frame 10 are then sent as they are to the next step, an adhesive application step, and then sequentially to a face material pasting step and a pressing step to form a panel. Note that these adhesive application steps, face material pasting steps, and pressing steps are performed in the same manner as conventional methods except that the framework 2 is fixed to the framework frame 10.

[0083] During the process from the framework to the above-mentioned process, the frame materials 1a, 1b forming the framework 2 and the reinforcing core materials 2a,
2b are not particularly joined together using adhesive or nails. However, the stile materials 1a, 1b and the reinforcing core materials 2a, 2 are fixed in the shape of the frame body by the framework frame 10 by applying the adhesive, pasting the facing materials, and pressing the facing materials.
By pasting the facing material 4 on b, each frame material 1a, 1b
Then, the reinforcing core materials 2a and 2b are joined to the shape of the framework 2. That is, each frame material 1a, 1b and reinforcing core material 2a, 2b are joined via the face plate 4.

Further, after the pressing process is completed, the framework frame 10 is placed on the work table 6 as shown in FIGS. 1 and 2.
0 is conveyed to the demolding machine in a horizontal state from the rear side of the demolding machine, as schematically shown in FIG. Then, the framework frame 10 placed on the work table 60 is moved to the lever 3.
0 and move the guide plates 17a, 17b... to create the first movable ruler 13 and the second movable ruler 14.
is separated from framework 2. Next, by operating the drive motor 93a of the reversing machine 90, the suction means is pushed out onto the working table of the demolding machine by the transmission wheel 93c.

At this time, the chain 66 that pulls up the work table 60 from a horizontal state to a state inclined at approximately 45 degrees is wound around and latched to the third gear 67c, as shown in FIG. Therefore, the chain 66 does not interfere with the movement of the suction means 80.

Next, the piston rods 81a of the plurality of cylinder devices 81 of the suction means 80 are moved to the suction disc 8 at the tip thereof.
2 extends downward until it comes into contact with the wooden panel P. Then, when the suction disc 82 comes into contact with the face plate 4 of the wooden panel P, the vacuum pump is activated to cause the suction disc to attract the face plate of the wooden panel P. Then, by retracting the piston rod 81a of the cylinder device 81 upward, the wooden panel P is removed from the frame 10 and lifted up.

At this time, since the framework 2 is fixed to the framework frame 10 only by the horizontal urging force of the leaf spring 15, it is possible to remove it from the framework frame 10 by moving the framework 2 upward. can. In addition, since the face plate 4 is bonded to the frame body 1 with a quick-acting adhesive, it is firmly bonded when pressed with a press machine, and the face plate 4
Even if the wooden panel P is lifted by suctioning and pulling it upward, the face plate 4 will not be peeled off from the frame body 1.

Next, the suction means with the wooden panel P suspended is moved back by the drive mechanism 93 between two rotations 92 of the reversing machine 90. Then, the electric motor 94 is operated while the wood panel P is being sucked, and the drive wheel 9
3 rotates the rotary cylinder 92. As a result, the surface of the wood panel to which the face plate is not attached faces upward. In this state, the vacuum pump is stopped, and the wood panel is transported to the next process, which is filling with insulation material.

On the other hand, the empty framework frame 1 of the demolding machine
0 will be returned onto the jig table 50. At this time, first, the guide rail 61 that guided the suction means 80 is flipped upward by the operation of the electric motor 61c. The work table 60 is tilted at approximately 45 degrees corresponding to the flat plate 51 of the jig table 50 by pulling up the chain 66 by the operation of the electric motor 67f.

At this time, the chain 66 is connected to the third gear 6
It comes off naturally from 7c. Further, when the work table 60 is to be horizontal, the chain 66 is hung on the third gear 67c when the projecting piece 60b of the work table 60 passes over the third gear 67c. Next, it is transported to the jig stand 50 by a transport mechanism similar to the transport mechanism for the framework frame 10 shown in FIG. That is, the framework frame 10 is pushed onto the jig stand 50 by the transport arm 52b. At this time, the suction means 8
Since the guide rail 61 that guides the robot 0 onto the work table 60 is flipped upward, it does not interfere with the movement of the framework frame 10.

[0091] The framework frame 10 is mounted on a jig stand 50.
The above will be used to manufacture the next wood panel P. Further, the demolded wooden panel is filled with a heat insulating material and then sent to the face plate pasting process again to complete the wooden panel P. As described above, according to the wood-based panel demolding machine in the wood-based panel production line of this embodiment, one side of the frame 1 is removed from the frame for framing the frame 1 of the wood-based panel P and holding it in that state. The wooden panel P with the face plate 4 pasted thereon can be automatically demolded, and the empty framework frame 10 can be used as a jig stand 50 to serve as a workbench for the framework.
It can be returned to the flat plate 51 tilted at approximately 45 degrees.

[0092] Also, from the framework frame 10, the wooden panel P
When the suction means 80 that pulls up the work table 60 moves onto the work table 60, the chain that tilts and supports the work table 60 in a state corresponding to the flat plate 51 is hooked to the third gear. It does not interfere with movement.

When the work table 60 is tilted in order to return the empty frame 10 to the flat plate 51 of the jig stand 50 tilted at approximately 45 degrees, the guide rail 61 that guides the suction means 80 is , because it is thrown upwards,
There is no obstacle to tilting the work table 60, and there is no obstacle to returning the framework frame 10 to the jig table 50. It should be noted that the wood panel demolding machine of the present invention is not limited to the above-mentioned embodiments, and the specific structural requirements such as the shape and dimensions of each member can be changed as appropriate for implementation.

[0094]

Effects of the Invention As described above in detail, according to the wood panel demolding machine in the wood panel production line of the present invention, the frame for forming the frame of the wood panel and holding it in that state can be removed from the frame. , it is possible to automatically demold the wooden panel with a face plate attached to one side of the frame, and also to tilt the empty frame 1 at approximately 45 degrees to the jig stand that will be used as a workbench for the frame. It can be returned to the working surface.

[0095] Furthermore, when the suction means that pulls up the wooden panel from the framework frame moves onto the work table, there is a flexible linear member that tilts and supports the work table in a state corresponding to the work surface of the jig table. Because it is latched on the latching piece,
It does not interfere with the movement of the framework frame.

The guide rail that guides the suction means when tilting the work table to return the empty frame to the flat plate tilted at approximately 45 degrees on the jig table is
Since it is flipped upward, it does not become an obstacle to tilting the work table, nor does it become an obstacle to returning the framework frame to the jig table.
