Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fully automatic panel manufacturing apparatus, and more particularly to a conveying machine for conveying glued core material to a polymerization section.

Conventionally, many panels are manufactured by pressure-bonding and polymerizing an upper plate B and a lower plate C on the front and back surfaces of a core material A. Therefore, the panel manufacturing equipment includes a process of applying glue to the front and back surfaces of core material A, a process of stacking upper plate B and lower plate C on core material A to form a polymer, and a process of crimping the polymer. It consists of a cold press process and conveyance equipment installed between each process.

Conventionally, as a means for conveying a core material having glue adhered to its front and back surfaces to the next step (polymerization section), the core material is placed on a chain conveyor and conveyed. Therefore, the glued state of the back surface comes into contact with the chain conveyor, which impairs the glued state.

Therefore, it has become an important issue to transport the adhesive without damaging the glued state.

The fully automatic panel manufacturing apparatus of the present invention is configured to press an upper plate B and a lower plate C onto the front and back surfaces of a core material A to form a product panel D, as shown in FIG. be.

FIG. 2 shows a side view of the apparatus of the present invention, in which 20 is a gluing machine, and the gluing machine 20 with the core material A having a thickness of about 12 to 30 mm is inserted into the rollers 2 and 2'. As a result, the core material A is discharged to the next process while being glued on both sides.

Next, as is clear from FIG. 3 showing the plan view of the apparatus, the core material A discharged from the gluing machine 20 is transferred to the guide roller ′ while the side surface of the core material A is being pinched.
A positioning stopper 6 installed in front of the transfer machine 10 is conveyed to the overlapping section 3 while being sandwiched between a pair of side belt conveyors 4, 4 rotating through the transfer machine 10.
It stops when it comes into contact with. Furthermore, by detecting that the core material A has arrived at that position, the side belt conveyors 4, 4 shown in FIG. It is rotatably formed to open the cover. Due to this rotation, the core material A sandwiched between the side belt conveyors 4, 4 is transferred to the belt conveyor 5, which will be described later.
fall on top. The transfer and mounting 10 is for transporting the upper plate B and the lower plate C directly above where the core material A has stopped (overlapping part 3). 13 etc., the suction cup 13
Then, the upper plate B and the lower plate C are adsorbed, the stopping position (overlapping part 3) of the core material A is horizontally held, and the core material A is separated and dropped.
In addition, the width of the lower plate C is the width of the side belt conveyor 4, 4.
Because it is wider than the width between the belt conveyors 5 and 5, the belt conveyor 5 is
drop it on top.

The belt conveyor 5 that conveys the polymer in which the above-mentioned upper plate B, core material A, and lower plate C are overlapped,
located at the bottom of the side belt conveyor 4,
It is installed approximately from the left end of the transfer machine 10 to the discharge conveyor 8 via the cold press machine 7.

7 is a cold press, and is a press for compressing the polymer conveyed by the belt conveyor 5.

Next, a manufacturing process of a product panel based on the above configuration will be explained.

First, in advance, the transfer machine 10 horizontally holds the lower plate C up to the overlapping part 3, which is the position where the core material A stops, and then allows the lower plate C to fall between the side belt conveyors 4, 4. side belt conveyor 4
The lower plate C is removed from the transfer machine 10 and placed on the belt conveyor 5 in the open state in which the lower plate C is rotated outward from each other around the rotating shaft 12 of the lower plate C.

On the other hand, in order to paste the core material A on the front and back surfaces of the core material A, the roller 2 of the gluing machine 20, which has glue on it,
Insert into 2'. The glued core material A is conveyed to the overlapping section 3 while being sandwiched between side belt conveyors 4, 4, and is brought into contact with a positioning stopper 6 and stopped. At this time, since the side belt conveyors 4, 4 pinch and convey the side surface of the core material A, that is, the surface to which no glue is applied, it is possible to convey the core material A with the glue still attached to it.

Then, by rotating the side belt conveyors 4, 4 outward from each other around the rotating shafts 12, 12, the core material A separates from the side belt conveyors 4, 4 and falls onto the lower plate C. do. After that, the upper plate B is transferred again by the transfer machine 10.
The upper plate B is transferred by holding it horizontally and rotating outward from each other around the rotating shaft 12 of the side belt conveyor 4 so that it can fall between the side belt conveyors 4 and 4. It is separated from the loading machine 10 and dropped onto the core material A.

Through the above steps, the sandwiched polymers of the lower plate C, the core material A, and the upper plate B are placed on the belt conveyor 5, and transported by the belt conveyor 5 to the cold press machine 7. Then, the cold press machine 7 press-polymerizes the polymer to produce the panel D, which is transported to the discharge conveyor 8 by the belt conveyor 5.

The panel manufacturing apparatus of the present invention having the above configuration includes a side belt conveyor 4 that pinches the side surface of the core material A for conveyance to the overlapping section 3 after gluing the core material A;
4, it is possible to transport the core material A without damaging the adhesive state on the front and back surfaces.
