Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for bending a short side edge of a building panel exterior base plate, which is used in a process of manufacturing a building panel used as an outer wall material of a general house such as a prefabricated house. ..

[0002]

2. Description of the Related Art As an outer wall material of a prefabricated house, one outer surface (usually an outer surface of a heat insulating plate) and a peripheral surface of a panel mainly composed of a metal frame and a heat insulating plate such as a gypsum board are made of a thin metal plate such as aluminum. A building panel is known in which the exterior base plate is covered with a coating, and a paint is sprayed on the surface of the exterior base plate to apply makeup.

By the way, in the process of manufacturing such a building panel, when the panel main body is covered with the exterior base plate, first, the panel main body is placed on the exterior base plate and both are adhered, and then the exterior base plate is attached. The long side edge of the main plate is bent upward, the edge is attached to the long side surface of the panel main body, and then both short side edges of the exterior base plate are bent upward to make the panel main body. The method of attaching to the side surface of the short side is performed.

In this method, the bending of the long side edges of the exterior base plate has a plurality of pairs of rolls whose axes are gradually raised from the horizontal position to the vertical position in order from the leading end. A bending machine is used, and the long side edges of the exterior base plate are bent so as to be gradually drawn up by the roll group while passing through the bending machine.

On the other hand, for bending the short side edges of the exterior base plate, a panel main body or the like sent out in the longitudinal direction from the bending machine for the long side edges is received at a predetermined working position. A receiving roller, a clamp that fixes the panel main body etc. to the working position, a pair of bending plates provided at both ends of the working position, and a folding jig that folds the excess parts generated at the four corners of the exterior base plate to the short sides. And a roll group that bends the edge of the exterior base plate protruding from the upper edge of the short side of the panel main body to the upper surface of the panel main body (upper surface of the frame on the short side side). Both of the short side edges of the exterior base plate are bent upward at once by the bending plate, and then the edges thereof are further bent by the roll group.

[0006]

By the way, the size of the building panel naturally varies depending on the place where it is used, and in recent years, the tendency of high-mix low-volume production is remarkable. Therefore, each of the above-mentioned bending machines also needs to be adapted to this.

Therefore, among the above-mentioned bending forming machines, in the bending forming machine that bends the long side edges of the exterior base plate, conventionally, the interval between the roll groups facing each other is set to the short side of the panel. This is dealt with by narrowing or widening it according to the size of, and the mechanism and work for this are relatively easy. However, the bending machine that bends the short side edges of the exterior base plate does not work like a bending machine for the long side edges because of its mechanism, and it has the above-mentioned size. Changes could not be dealt with quickly and easily.

That is, the conventional bending machine for the short side edges uses a pair of folding plates having a length substantially the same as the length of the short side edges of the exterior base plate. Every time the dimension of the short side of the building panel changes, it must be replaced with a bent plate having a length according to that dimension. Moreover, since the bent plate is made of iron and its weight is very large, this replacement is required. The work requires a great deal of labor and time, and is also dangerous. In addition, since the quality of the building panel is greatly affected by the accuracy of the bending plate installation, meticulous attention and high skill are required to replace the bending plate, which makes the replacement work extremely troublesome. there were. Furthermore, since the length of the folding plate is approximately the same as the dimension of the short side of the building panel, it is necessary to prepare the number of folding plates according to the size type of the building panel, Therefore, the facility cost is increased, and it is necessary to secure a storage place for the bent plate, which is inconvenient in a factory where space saving is desired. In addition, the interval between the bent plates facing each other is adjusted according to the length of the long side of the building panel. In that case, when the interval is narrowed, one of the receiving rollers located between these bent plates is adjusted. Since the part will interfere with one of the folding plates, it is necessary to remove the receiving roller that interferes with this. Also, when restoring the spacing of the folding plate (widening the spacing), the receiving roller previously removed. Had to reattach. Detaching the receiving roller like this is very troublesome like replacing the folding plate.Furthermore, when both the long side and the short side of the building panel are changed, the folding plate is replaced and the receiving roller is replaced. Both the work of removing the roller and the work of removing the roller had to be carried out, which required a great deal of time as well as labor. Therefore, during that time, the entire manufacturing line of the panel for buildings was stopped, which was a major cause of lowering production efficiency.

The present invention has been made to solve the above-mentioned conventional problems, and is capable of quickly and easily responding to a change in size of a building panel, and a short side edge of a building panel exterior base plate. It is intended to provide a partial bending device.

SUMMARY OF THE INVENTION A short side edge bending apparatus for a building panel exterior base plate according to the present invention has a panel main outer surface and a peripheral surface composed of a frame and a heat insulating plate. When manufacturing a building panel that is covered with an exterior base plate made of a metal thin plate that is larger than the panel main body, each long side edge of the exterior base plate is bent in advance and is attached to each side of the long side of the panel main body in advance. The building panel in the attached state is received with the exterior base plate on the lower side, and the edges of each short side of the exterior base plate are bent upward so as to be attached to the short side surfaces of the panel main body, and the exterior Fold the surplus portions generated at the four corners of the base plate, fold each of the folded pieces on the outer surface side of the short side edge of the folded exterior base plate, and then project from the upper edge of the short side of the panel main body. Panel of the edge of the exterior base plate A device for bending to the upper surface of the short side of the body, comprising a plurality of transport mechanisms arranged on the lower surface side of a bending work area where the bending of the short side edge and the folding of the folding piece are performed. A panel receiving means for sending the building panel to a predetermined position in the bending work area, and a pair of end portions of the bending work area movably opposite to each other in accordance with the dimension of the long side of the panel, and an exterior base plate. A pair of short side edge bending means for bending both short side edges and folding the folding piece, and a pair of short side edge parts provided so as to be retractable in the folding work area. The panel sending means for sending out the panel in which the folding and the folding of the folding piece have been completed in the direction along the short side thereof, and the panel sending means are movable according to the dimension of the long side of the panel main body, and sent by the panel sending means. The edge of the exterior base plate protruding from the upper edge of the short side of the panel It is made and a short side forming means for forming the short-side by bending the short side upper surface of the panel main body.

The short side edge bending means is provided so as to be movable toward a position corresponding to the support base for supporting the short side edge of the panel main body from below and the four corners of the panel main body. Pressing and fixing means for pressing and fixing the vicinity of the four corners of the panel main body from above, and movably provided to positions corresponding to both ends of the short side edges of the exterior base plate, and the short side edges of the exterior base plate. A pair of bending plates that push up both ends of the portion at the same time to bend the entire short side edge portions upward, and are movable toward positions corresponding to the four corners of the panel main body and the four corners of the panel main body. Is provided so as to be reciprocally rotatable between the long side and the short side of the panel main body, and when the bending plate is bent, both ends of the side surface on the long side of the panel main body are Fold and press the excess part in cooperation with the bending plate After the completion of the bending by means of the above, it is provided with a folding piece folding means for pivoting to the short side of the panel main body and folding each of the folding pieces to the outer surface side of the short side edge of the exterior base plate. May be.

[0012]

The edges of the short sides of the exterior base plate are pressed only by the pair of bending plates, but the edges are entirely bent by this alone. This is because the pair of folding plates exhibit the same function as the conventional folding plates, that is, the single folding plate having substantially the same length as the short side edge portion. , This has been confirmed in the actual machine. The pair of bent plates are movable toward positions corresponding to both ends of the short side edge portion, that is, movable in the direction along the short side of the panel main body and at the same time as the long side of the panel main body. Since it is also movable along the direction, even if both the long side and the short side of the building panel are changed, it can be easily dealt with by simply moving the bending plate in the predetermined direction.

Moreover, since the pair of bending plates press only both ends of the short side edges of the exterior base plate, each bending plate can have a constant size. There is no need to prepare folding plates of other sizes.

Further, the panel receiving means for receiving the panel in the folding work area is composed of a plurality of carrying mechanisms, and each of these carrying mechanisms can be retracted downward from the lower surface (panel carrying surface) of the folding work area. Therefore, when the size of the building panel is changed and the gap between the pair of folding plates facing each other across the panel is narrowed, only the transport mechanism that interferes with the folding plates is retracted downward. Good.

As the short side of the panel passes under the first side, the edge E is gradually pressed against the upper surface of the short side. Further, among the forming rolls 41, the forming roll group 411 located on the side closer to the long-side side edge bending device 9 is fixed at that position, and the forming rolls located on the opposite side to this. The group 412 can be moved toward and away from the fixed side by the position adjusting mechanism 7 described above.

Next, details of the pair of short side edge bending means 2 will be described. Note that, here, since the short side edge bending means have the same configuration except that the directions thereof are opposite to each other, only one of them will be described.

The short side edge bending means 2 is provided with a support base 21.
The pressure fixing means 22, the pair of bending plates 23, and the folding piece folding means. The support base 21 supports the short side edge portion of the panel main body F from below. A single metal plate having a smooth upper surface is used for the support base 21. The length of the support base 21 is sufficiently longer than the short side of the building panel having the largest size.

The pressing and fixing means 22 presses and fixes the vicinity of the four corners of the panel main body F from above. The pressing and fixing means 22 is composed of a substantially L-shaped clamp that moves up and down by a hydraulic cylinder, an air cylinder, or the like. Each clamp 221 is suspended from a support plate (not shown) via a support shaft 222, and these clamps 221 are provided so as to be movable toward both ends of the short side edge D of the exterior base plate B. There is.

The bending plate 23 pushes up both ends of the short side edge D of the exterior base plate B at the same time and bends the entire short side edge D upward. Each of these folding plates 23 is shown in FIG.
As shown in FIG. 4, the pressing surface 231 that presses the short side edge D and the inclined surface 232 that is a relatively short metal plate that is bent and formed in a substantially V-shape form an angle of 135 degrees. Is playing. A pair of folding plates 23 thus formed
Are mounted on a rotary unit 24 which undulates the inclined surfaces 232 of each other by a predetermined angle. The rotation unit 24 has a notch 2 along the longitudinal direction on the front surface.

And an electric motor (not shown) connected to the screw shaft 243 via a gear 244,
The bent plate 23 is mounted on the bent plate mounting block 245 with a bolt or the like (not shown). The rotation unit 24 thus configured is at a height position such that the pressing surface 231 of the bending plate 23 and the upper surface of the support base 21 are substantially flush with each other, and is supported by the bending plate 23. It is provided at a position where a predetermined clearance is secured between it and the table 21. Further, the bearing shaft 246 of the rotation unit 24 has
It is set so as to pass through the center of the clearance secured between the support base 21 and the bending plate 23. As a result, when the rotating unit 24 rotates, the bending plate 23 undulates around the center of the clearance as a fulcrum, and wrinkles occur on the short side edge D of the exterior base plate B during bending. Alternatively, the exterior base plate B does not bulge at the short side edges of the panel main body F. Further, since the screw shaft 243 is rotated in the forward and reverse directions by the electric motor (not shown), each bending plate 23 causes the short side edge portion D of the exterior base plate B.
It is designed to move toward both ends. In addition,
Reference numeral 247 in the figure denotes a bearing that supports the bearing shaft 246 located on the short side forming means 4 side.

Both of them are movable toward both ends of the short side edge portion D of the exterior base plate B. In addition, this folding jig 25
1 is reciprocally rotatable about the corner of the panel main body F between the long side and the short side of the panel main body F.

Reference numeral 8 in FIG. 1 indicates a positioning stopper, which is a transport mechanism 11.
It comes into contact with the tip of the panel sent by and stops the panel at a predetermined position.

Next, the operation of the present apparatus having the above configuration will be described. 3 to 8 of the drawings referred to here, the operation of the clamp 221 of the short side edge bending means 2, the folding plate 23 and the folding jig 251 of the present device, and these 221 and 23. , 251 and the building panel A, and FIGS. 9 to 12 show only the bending process of the exterior base plate B, particularly the short side edge bending means 2
The operation of is designed to be briefly shown.

The initial setting of the apparatus is performed prior to the start of the bending of the short side edge D of the exterior base plate B, and the initial setting of the apparatus is performed at a position corresponding to the size of the building panel to be bent. Each means 1 to 4 is arranged. That is, when a building panel with a short long side is sent, the transport mechanism 11
Of the above, the unnecessary transport mechanism 11 retracts from the folding work area 5, and the movable sides of the short side edge bending means 2 and the short side forming means 4 are the long side edge bending forming device 9 side. Move to. Further, when a building panel with a short side having a short dimension is sent, the bending plate 23, the clamp 221, and the folding plate 23, which is located farther from the short side forming means 4, of the short side edge bending means 2. The jig 251 moves to the short side forming means 4 side. Furthermore, when a building panel with short dimensions on both the long side and the short side is sent, both of the above two operations are performed.

When the above initial setting is completed, the present apparatus stands by and waits for the panel sent out from the long side edge bending device 9. That is, as shown in FIG. 3, the folding plate 23 of the short side edge bending means 2 is horizontal, the clamp 221 is at the top dead center position, and the folding jig 25 is provided.
1 is on both sides of the bending work area 5, and waits for a panel respectively.

Next, in the long side edge bending device 9, a panel in which the long side edge C of the exterior base plate B is bent is sent out from the device 9 as shown in FIG. The transport mechanism 11 receives the panel and sends it to a predetermined position in the bending work area 5 (see FIG. 4). When the panel reaches a predetermined position, that is, when the head of the panel comes into contact with the positioning stopper 8, the transport mechanism 11 stops. At this time, the edge of the panel main body F on the short side and the edge of the support base 21 are exactly aligned.

When the panel stops at a predetermined position, as shown in FIG. 5, the clamps 22 located above the four corners of the panel are placed.
1 moves down and presses the four corners of the upper surface of the panel main body F. At the same time, the folding jigs 251 that are slightly open on both sides of the folding work area 5 move in the direction to close each other, and press both ends of the long side surface of the panel main body F. This secures the panel in place.

When the fixing of the panel is completed, the bending unit 23 is erected by the rotation of the rotating unit 24 as shown in FIG. 6, and the both ends of the short side edge D of the exterior base plate B are pushed up. At this time, the folding jig 251 pressing both ends of the side surface on the long side of the panel main body F and the bending plate 23 are joined to each other through their respective inclined surfaces, and the four corners of the exterior base plate B are formed by these inclined surfaces. The surplus portion of the sheet will be folded as shown in FIG.

When the bending of the short side edge portion D and the folding of the surplus portion are completed as described above, the rotating unit 2
4 returns to the original position, and the folding plate 23 returns to the horizontal state again as shown in FIG.

When the folding plate 23 is returned to the horizontal state, the folding jig 251 is rotated 135 degrees from the long side surface G of the panel main body F to the short side surface of the panel main body F as shown in FIG. The folding piece K formed in the step is folded into the outer surface side of the short side edge portion D of the exterior base plate B as shown in FIG. 11.

When the folding pieces K at the four corners of the panel are completely folded, the clamps 221 pressing the four corners of the upper surface of the panel main body F are lifted to open the panel main body F. Then, the delivery roller 31 of the panel delivery means 3 is raised to lift the panel from the transport mechanism 11, and the delivery claw is lowered to engage with the panel to deliver the panel toward the short side forming means 4 side.

The panel thus sent out from the folding work area 5 passes through the short side forming means 4, and this means 5
By the forming roll 41, the edge E of the exterior base plate B protruding from the upper edge of the short side of the panel main body F is bent to the upper surface of the short side of the panel main body F as shown in FIG. When the panel exits the bending work area 5, the folding jig 251 that has been rotated to the short side of the panel main body F returns to the standby position (see FIG. 3) and waits for the next panel.

By repeating the above operation in sequence, the short side edges of the exterior base plate of the building panel are bent and formed one after another.

[0042]

As described above, the apparatus according to the present invention bends by pressing the entire surface of each short side edge portion of the exterior base plate with a single bent plate as in the prior art. Instead, the pair of folding plates presses only both ends of each short side edge, and the pair of folding plates move toward the positions corresponding to both ends of the short side edge. It is possible, that is, it is movable in the direction along the short side of the panel main body, and it is also movable in the direction along the long side of the panel main body, so both the long side and the short side of the building panel are Even if it is changed, it is only necessary to move the bending plate in a predetermined direction, and unlike the conventional case, it is not necessary to prepare bending plates of various kinds of sizes. Therefore, it is possible to completely eliminate the work of exchanging the bent plate due to the size change of the building panel, which is required in the conventional device, and as a result, it is possible to dramatically improve the productivity and the work safety. ..

Further, the panel receiving means for receiving the panel in the folding work area is composed of a plurality of carrying mechanisms, and each of these carrying mechanisms can be retracted downward from the lower surface (panel carrying surface) of the folding work area. Therefore, when the size of the building panel is changed and the gap between the pair of folding plates facing each other across the panel is narrowed, only the transport mechanism that interferes with the folding plates is retracted downward. Good. Therefore,
It is possible to completely eliminate the work of attaching and detaching the transport roller, which was necessary in the conventional device, and this also contributes to the improvement of productivity and work safety.
