Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a panel manufacturing apparatus suitable for use in manufacturing bathroom ceiling panels and the like.

An object of the present invention is to enable this type of panel, which requires many processing steps, to be manufactured on an integrated production line, thereby improving productivity by shortening processing time and reducing the number of workers. .

The configuration of the present invention will be described below with reference to the drawings.

FIG. 1 shows an integrated line 1 of an apparatus for manufacturing ceiling panels for bathrooms, etc., according to the present invention.

A pallet stand 2 is provided at the starting end of the line 1, and original plates 4 are loaded on the pallet stand. Original plate 4
are made of PVC-coated steel plates, etc., and are loaded with the product side (in the case of ceiling panels, the indoor side) facing up.

Reference numeral 5 designates a cutting device provided in the first production process, and an insertion conveyor 6 and a delivery conveyor 7 are provided in front of and behind the cutting device, respectively. The cutting device 5 cuts the four corners of the rectangular original plate 4. The cut portions are indicated by 8a, 8b, 8c, and 8d. Since the four sides of the original plate 4 are bent and formed in the process described later, the four corners are cut by the width of the forming process. The cutting device 5 is equipped with two cutting heads 5a and 5b. First, both corner portions 8a and 8b at the leading end of the original plate 4 sent by the insertion conveyor 6 are cut by the cutting heads 5a and 5b. After cutting both corner portions 8a and 8b, the original plate 4 is passed through the cutting heads 5a and 5b. The original plate 4 that has once passed through the cutting heads 5a and 5b is sent back as the delivery conveyor 7 retreats. After that, both corners 8c and 8d of the rear end of the original plate 4 are removed using the cutting head 5.
Cut with a and 5b.

The original plate 4 whose four corners have been cut in this manner is sent to the first press 10, where mounting holes and the like are formed at predetermined positions. 11a and 11b are the first press 1
This is a transport conveyor placed before and after 0.

The original plate 4 passed through the first press 10 is sent to a four-side forming machine 12. The four-sided forming machine has two opposing bending heads 13a and 13b arranged parallel to each other with an interval between them, and a turntable 15 for rotating the original plate 4 forward and backward by 90 degrees is provided between the two bending heads. It is provided. Opposing bending heads 13a, 13b
The space between the two faces can be increased or decreased in order to match the distance between the long side and the short side of the original plate 4. bending head 1
After inserting the original plate 4 between 3a and 13b and adjusting the interval between the bending heads to match the length of the long side 4a of the original plate 4, both short sides 4b and 4b of the original plate 4 are inserted into the bending head. It is bent and formed at 13a and 13b. After that, the original plate 4 is rotated by 90 degrees on the turntable 15, the interval between the bending heads 13a and 13b is adjusted to match the length of the short side 4b of the original plate 4, and the original plate 4 is rotated by 90 degrees.
Bend both long sides 4a, 4a of the head 13a, 13b.
Bend and form. In this way, the four sides of the original plate 4 are bent and formed.

The original plate 4 sent out from the four-side forming machine 12 is inserted into the second press 16. In the second press 16, an inspection hole 17 is formed. 18 is a conveyor, and 20 is a direction change conveyor for changing the direction of the original plate 4. Moreover, 19a and 19b are conveyors disposed before and after the second press 16.

Although not shown, the second press 16 is equipped with a cylindrical punch, and a cutting edge is provided on the inner circumference of the lower end of the punch.
Bending blades are formed on the outer periphery of the lower end, and a cutting die and a bending die are provided as dies corresponding to the punches. In the second press 16 configured in this way, the original plate 4
An inspection port hole 17 is formed in the middle, and at the same time a rising piece 9 is formed around the periphery of the hole.

In addition, the reference numeral 21 in the figure is a female bending machine, and if necessary for female bending, the original plate 4 is taken offline and transferred to the female bending machine, and after processing, the original plate 4 is
Return to the original line 1 again.

Further, the reference numeral 22 in the figure is a third press, and when it is necessary to form other holes for a dryer, etc., the original plate 4 is taken offline and the holes are drilled by this press. After drilling, the original plate 4 is returned to the hole line 1 again.

After the inspection hole 17 is formed by the second press 16, the original plate 4 is sent to the reversing machine 23 by the conveyor 19b. The original plate 4 is turned over by the turning machine and transferred to the slat conveyor 24.

The slat conveyor 24 is provided with an adhesive spraying booth 25.
Adhesive is automatically sprayed at predetermined locations on the original plate 4 transported in step 4 within the booth.

The original plate 4 sprayed with adhesive is transferred to a free conveyor 26, and a heat insulating material such as styrofoam, a wooden frame 27, etc. are attached to the original plate 4 placed on the free conveyor to complete the ceiling panel A. The completed ceiling panel A is transferred to a product mounting pallet (not shown), and the inspection opening hole 17 is covered with a lid 28.

In addition, when transferring the original plate 4 from the pallet table 2 to the insertion conveyor 6, when clamping the original plate 4 to the first press 10, and when transferring the original plate 4 from the first press 10 to the four-sided forming machine, etc., this is done manually. Alternatively, this may be performed by an automated device, but when the original sheet 4 is transferred off-line to the female bending machine 21 or the third press 22, it is performed manually.

Although this embodiment has been described with respect to manufacturing ceiling panels for bathrooms and the like, the apparatus according to the present invention can also be applied to manufacturing other panels such as wall panels and floor panels.

As explained above, since the apparatus for manufacturing ceiling panels for bathrooms, etc. according to the present invention is equipped with a corner cutting device and a four-side forming machine, the panel can be formed more easily than when forming by a single press or the like. In addition to shortening the processing time per piece and greatly reducing the number of personnel involved in production, the corner cutting device and four-side forming machine are each equipped with two cutting heads and a bending head. The equipment cost can be significantly reduced.
