2. Description of the Related Art Conventionally, in a wood-based prefabricated house or the like, a means for constructing walls, floors, roofs or the like with wood panels has been used. As a wooden panel applied to the construction of such a prefabricated house, for example, FIG.
There is a structure as shown in. This wood panel has reinforcing core members 2a, 2b extending vertically and horizontally inside a frame body 1 assembled in a rectangular frame shape by frame members (core members) 1a, 1b forming vertical and horizontal frames. A frame 2 is provided by arranging the frame body 2 and a heat insulating material 3 such as glass wool is filled in the interior surrounded by the reinforcing core materials 2a and 2b and the vertical and horizontal frame materials 1a and 1b.
The surface materials 4, 4 made of plywood are attached to both the front and back sides of the above.

By the way, when manufacturing such a conventional wooden panel, the frame 1 and the longitudinal and lateral reinforcing core materials 2a, 2 are used.
In manufacturing the frame 2 made of b, as a pre-process, the vertical and horizontal frame members 1a, 1b forming the frame body 1 are subjected to the incision grooving process, and the frame members are formed by combining the inversion grooves of these frame members 1a, 1b. 1 and a reinforcing core material 2a, 2b is provided inside the frame body 1.
There is used a means of forming a frame 2 by assembling a cross shape or the like and attaching plywood (face material) 4, 4 to both surfaces of the frame 2. Then, these manufacturing steps are conventionally carried out by using a manufacturing apparatus as shown in FIG.

Explaining this manufacturing process, first, a work frame 5 having a horizontal flat plate 5a is provided with a frame member 1 which has been subjected to an indirect groove processing.
Two workers A and B carrying a and 1b put these frames 1
After assembling a and 1b in a frame shape, the frame body 1 assembled in a frame shape is transferred to the next work table 6 having a flat plate 6a which is also horizontal, and is assembled in a cross shape on the work table 6. The reinforcing core materials 2a and 2bb are attached. The frame members 1a, 1b and the reinforcing core members 2a, 2b are
It goes without saying that the workers A and B are nailed.

Next, an adhesive is applied to the frame 2 in which the reinforcing cores 2a and 2b are attached to the frame 1 by an adhesive applying device 7 having an adhesive roller 7a for applying the adhesive. Then, on the flat plate 8a of the workbench 8, the face material 4 is attached to one surface of the frame 2, and the face material 4 is turned upside down and sent to the adhesive applying device 7, and the adhesive roller 7a of the adhesive applying device 7 is passed through to form the frame. Apply adhesive to the other side of 2.

Then, at the same time when the adhesive is applied, the frame 2
22 is filled with the heat insulating material 3 cut into a predetermined size and shape, and the face material 4 is attached to the flat plate 9a of the workbench 9 from the upper surface of the frame 2 to manufacture a wood panel as shown in FIG. In addition, the frame 1 and the plywood are made to have a large outer dimension in consideration of a finishing allowance in advance, and after a manufacturing process by a manufacturing apparatus as shown in FIG. 23, a normal sizer process is performed as a post process, Consideration is given to the specified dimensions.

However, there are the following disadvantages in the production of the above-mentioned wood panel. When fixing the frame body 1 to the frame, place the frame members 1a and 1b directly on the workbench,
After assembling in this state and sending it to the next process, at that time, since it is simply assembled by using the pre-formed recessed groove, overall dimensions, squareness, straightness, flatness etc. are not sufficiently secured. There is a risk of being framed and sent to the next process, so it is somewhat difficult to obtain a uniform and high-quality wood panel without variation.

Further, since the frame work is performed simply by using the recessed grooves in this manner, a large amount of operator's intuition is required in order to give the frame 1 a sufficiently accurate squareness and straightness. Therefore, it requires a high degree of skill of the worker and also takes time and labor, so that improvement in productivity cannot be expected.

Therefore, the present applicant has filed Japanese Patent Application No. 1-3432.
Proposed frame frame for wood panel production shown in FIG.
The wooden frame manufacturing frame is a rectangular frame-shaped fixed frame placed on a jig table for manufacturing a wooden panel, and a pair of opposite sides of the fixed frame in a state orthogonal to these sides. The attached first movable bar and the second movable bar attached in a state of being orthogonal to the pair of opposite sides and another pair of sides are orthogonal to the attached sides, respectively. It is configured such that it can move while being maintained in the above state. The frame member is framed along a square frame constituted by the fixed frame and the first and second movable bars to solve the above problems.

[0010]

By the way, when manufacturing a wood panel using the above-mentioned frame, after the frame is framed in the frame, the adhesive is applied to the frame and the frame is applied. The face plate is attached. However, since the frame is fixed to the frame frame,
Since it is impossible to fill the heat insulating agent into the wood panel and to attach the face plate to the back surface of the wood panel, it is necessary to remove the wood panel from the frame and turn it over.

Therefore, in order to automate the production of the wood panel, a demolding machine for removing the wood panel from the frame is required. Then, this demolding machine, in automating the production of the wood panel using the frame, has a function of removing the frame from the frame, a function of sending the removed frame to the next step for reversing, and a frame. It is necessary to have a function of transferring the framed frame removed from the body to the framed work table which is the first step of the manufacturing line.

The present invention has been made in view of the above circumstances, and an object thereof is to automatically remove the frame body from the frame frame when manufacturing the wood panel using the frame frame, and to remove the frame body. It is an object of the present invention to provide a wood panel demolding machine in a wood panel manufacturing line that can be sent to the next step and can return an empty frame to the first step.

[0013]

In order to achieve the above object, the present invention provides a rectangular plate-shaped work table on which a framing frame is mounted, and the wood panel which is laterally moved on the work table. A rectangular suction means for sucking and lifting the workpiece, two guide rails that support the suction means from both sides and guide the work table, and a support base that supports the work table and the guide rail. The work table has a front portion rotatably supported by a support table, and projecting sides projecting left and right from both ends of the rear portion of the work table are provided. When the work table rotates, a hooking piece is provided that extends on a substantially circumference that serves as a trajectory of the projecting piece.The projecting piece has a work table upper surface that is pulled up from above the work table. Each flexible linear body that supports the inclined work surface of the jig table is provided, and the linear body is hooked on the hooking piece with the work table in a horizontal state. The two guide rails are supported above the work table in parallel along the moving direction of the suction means at intervals of the width of the suction means by a support portion extending substantially horizontally from the front part and the rear part of the support base. The supporting portion is characterized in that one end thereof supports the guide rail and the other end thereof is rotatably supported by the support base so that the guide rail is directed upward.

[0014]

According to the wood panel demolding machine of the present invention, the framework frame sent from the face plate pressing machine, which is the previous step, 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 sucking the face plate of the wooden panel fixed to the frame, the wooden panel is removed from the frame and lifted. Next, the suction means moves to the next step along the guide rail while sucking the wood panel.

After the suction means is moved, the work table is lifted on one side by the flexible linear body, and the work table upper surface is inclined at a predetermined angle. This is because the working surface of the jig base for fixing the core material to the framework frame is bent at an angle of about 45 degrees to facilitate the work. The work table is tilted so that it can be returned easily. Before the work table is tilted, the guide rail is raised so as not to interfere with the tilted work table.

In addition, the flexible linear body has its central portion hooked on the hooking piece so as not to interfere with the suction means which is guided and moved by the guide rail when the work table is horizontally lowered. Be stopped.

Next, a method of manufacturing a wood panel using a wood panel demolding machine in the wood panel manufacturing line having the above-described structure will be described. First, the framework frame 10 is placed on the work surface of the jig base 50. This frame frame
It was returned from the demolding machine. When the first movable ruler 13 and the second movable ruler 14 are returned, the first movable ruler 13 and the second movable ruler 14 are moved in the horizontal direction or the vertical direction according to the size and shape of the frame body 1 to be manufactured, so that the frame body is manufactured. The fitting pins 20 and 20 are fitted into the holes 17c and 17c at corresponding positions and fixed at the positions.

At this time, the lever 30 of the frame 12
Is lifted upward, and each guide plate 1

The first and second movable rulers 13 and 14 are moved away from the inner surface of the fixed frame 12 facing each other, that is, the first and second movable rulers 13 and 14c, respectively. Leave 14 loose. In this case, the first movable ruler 13 and the second movable ruler 14 are moved in advance to move the movable ruler 13 (14).
Since the distance between the movable ruler 13 (14) and the vertical / horizontal frames 12a, 12b is widened, the movable ruler 13 (14) and the vertical / horizontal frame 12a,
Even if the space between the frame 12a and the frame 12b is matched with the desired size of the frame 2 with extremely high accuracy, there is a margin for the operation of the lever 30, so that the mounting of each frame 1a (1b) becomes extremely easy.

Next, a magnetic card in 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. By this operation, a plurality of pre-coded support pins 56 are projected onto the framework frame and push up the leaf spring 15.

Next, the frame members 1a and 1b are arranged on the base 11 along the inner side surfaces 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 members 1 and 1b are fixed to the fixed frame 12 or the first and second movable rulers 13 and 14 and the leaf springs 15.
It is arranged between the pressing plate 15d pushed by the support pin 56 and pushed up by the pressing plate 15d.

Then, the reinforcing core materials 2a and 2b are installed on the frame frame 10. At this time, the reinforcing core materials 2a, 2b

Then, at the stage where all the frame members 1a, 1b and the reinforcing core members 2a, 2b are placed, the lever 30 of the frame frame 10 is tilted to move the first and second movable rulers 13, 14
By moving the frame members 1 and 1b and the reinforcing core members 2a and 2b placed in the shape of the framework 2 from above, below, left and right by moving in the direction of the vertical and horizontal frames 12a and 12b that oppose each other, Regulate to an accurate shape. At this time, the first and second
The movable rulers 13, 14 of the first to third link portions 3 are
The four guide plates 17a, 17b linked by 1a, 31b, 31c are moved in the orthogonal direction by moving the two guide plates 17a, 17b in the same direction by the operation of the lever 30.

Then, the first and second movable rulers 13, 1
By pressing the pressing plate 15d at almost the same time as tightening the frame 2,
The support pin 56 pushing up is moved downward. Then, by lowering the support pin 61, the pressing plate 15d urged by the leaf spring 15 causes the frame members 1a, 1b or the reinforcing core members 2a, 2b to face the leaf spring 15.
2, the first and second movable rulers 13 and 14, and the pressing plate 15d pressed by another plate spring 15 are pressed. Therefore, the frame members 1a and 1b and the reinforcing core members 2a and 2b are
The shape of the framework 2 to be formed is fixed to the framework frame 10.

Further, while the outer periphery of the completed framework 2 is fixed by the framework frame 10, the framework 2 and the framework frame 10 are slid by sliding on the work surface 51.
Can be sent to the next process in that state. Then, the frame 2 and the frame 10 are sent to the next step, that is, the adhesive applying step, and then sent to the face material attaching step and the pressing step in order to form a panel. The adhesive applying step, the face material attaching step, and the pressing step are performed in the same manner as in the conventional art except that the framework 2 is fixed to the framework 10.

Between the frame and the above steps, the frame members 1a, 1b and the reinforcing core members 2a, 2b forming the frame 2 are not joined by an adhesive or a nail.
However, by applying the adhesive, attaching the face material and pressing the face material, the face material 4 is fixed to the frame members 1a and 1b and the reinforcing core members 2a and 2b which are fixed to the shape of the frame by the frame frame 10. By being attached, the frame members 1a, 1b and the reinforcing core members 2a, 2b are joined to each other in the shape of the frame 2. That is, each of the frame members 1a and 1b and the reinforcing core members 2a and 2b

Next, the piston rods 81a of the plurality of cylinder devices 81 of the suction means 80 are attached to the suction plate 8 at the tip thereof.
2 extends downward until it contacts the wood panel P. Then, when the suction plate 82 comes into contact with the face plate 4 of the wooden panel P, the vacuum pump is operated to adsorb the face plate of the wooden panel P to the suction plate. Then, by retracting the piston rod 81a of the cylinder device 81 upward, the wood panel P is detached from the framework frame 10 and lifted.

At this time, since the framework 2 is fixed to the framework frame 10 only by the horizontal urging force of the leaf springs 15, it can be removed from the framework frame 10 by moving the framework 2 upward. it can. Further, since the face plate 4 is adhered to the frame body 1 with the immediate-acting adhesive, the face plate 4 is firmly adhered when pressed by the press machine.
Even if the wooden panel P is lifted up by sucking and pulling upward, the face plate 4 does not come off from the frame body 1.

Next, the suction means with the wooden panel P being lifted is retracted by the drive mechanism 93 between the two rotations 92 of the reversing machine 90. Then, the electric motor 94 is operated while the wood panel P is sucked, and the drive wheel 9
The rotating cylinder 92 is rotated by rotating 3. As a result, in the wood panel, the surface of the face plate on which the face plate is not attached faces upward. In this state, the vacuum pump is stopped and the wood panel is carried out to the next step of filling the heat insulating material.

On the other hand, the empty frame 1 of the demolding machine
0 will be returned to the jig table 50. At this time, first, the guide rail 61 that guides the suction means 80 is set in a state of being flipped up by the operation of the electric motor 61c. Then, the work table 60 is tilted at about 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 the third gear 6
It comes to come off from 7c naturally. Further, when the work table 60 is horizontal, the chain 66 is hooked 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 base 50 by a transport mechanism similar to the transport mechanism of the framework frame 10 shown in FIG. That is, the framework frame 10 is pushed out onto the jig base 50 by the transport arm 52b. At this time, the suction means 8
Guide rail 61 for guiding 0 on the work table 60
Is flipped up, so the frame 10
Does not interfere with the movement of the.

Then, the frame 10 comprises the jig base 50.
Above, it will be used to manufacture the next wood panel P.
