Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for manufacturing a core material used for doors or partition walls having heat insulating and sound absorbing properties.

Conventionally, in order to provide heat insulation and sound absorption properties to doors, partition walls, etc., it has been proposed to use paper cores whose spaces are filled with foamed urethane, glass wool, rock wool, etc. as a core material.

By the way, the core material is made by manually filling the space of a ready-made paper core with foamed urethane, etc., which has the drawback of poor productivity and therefore making products such as doors expensive.

The present invention has been made in order to solve the above-mentioned conventional drawbacks, and is a core material manufacturing apparatus that can produce a core material with high productivity by integrating foamed urethane etc. into a sandwich shape at the same time as manufacturing a paper core. This is what we are trying to provide.

Next, the present invention will be explained with reference to the drawings which are one embodiment.

FIG. 1 shows a schematic illustration of a core material manufacturing apparatus according to the present invention, in which 1 is a core material roll, 3 is a mat roll made of foamed urethane, glass wool, rock wool, etc. An adhesive is applied to the upper surface of the core material (paper) 2 from the core material roll 1, and then the core material 2 and the mat 4 are adhesively laminated together, and are made up of a large number of rotating blades at predetermined intervals. A large number of laminated belts 7 are formed by the slitter 6,
7, ... is cut. Then, as shown in FIG. 2, the many cut laminated strips 7, 7 are erected at 90 degrees by an erecting means 8 consisting of a plurality of rollers.
Move forward in close contact with each other.

In this way, a large number of laminated bands 7, 7, ... arranged in parallel in the horizontal direction are swung by the wave forming means 9 as described below, and in this swung state, the liner roll 1
6 and 18, and the front and back liners 17, 19 coated with adhesive by adhesive applying means 20, 20 are bonded from above and below in a sanderch state to form a continuous core material 21. This continuous core material 21 is then cut into a predetermined length by a cutter means 22, which is a cutting means described below, to obtain a desired product.

In addition, in the above embodiment, the laminated belt 7 is
I tried to change the direction of travel by 90 degrees, but
The direction change is not necessarily necessary, and the laminated strips 7 may be made to stand up in a straight state and then brought into close contact with each other by rollers.

The waveform forming means 9, as shown in FIG.
two rollers 10 having a large number of annular protrusions 11;
10 is rotatably provided on a substrate 12 so as to be pressed onto the upper and lower surfaces of the laminated band 7 with a predetermined pressure, and the substrate 12 is slidable perpendicular to the traveling direction of the laminated band 7. An arm 13 attached to the base plate 12 engages with an eccentric pin 15 provided on the rotating disk 14. Therefore, as the rotary disk 14 rotates, the rollers 10, 10 reciprocate in the direction of the arrow, forming the moving laminated band 7 in a wave shape.

Further, the blade 23 of the cutter means 22 is moved obliquely downward by a cylinder 25 attached to a gate-shaped frame 24, and the frame 24 is slidably mounted on a guide member 26 and is controlled by a motor 27. - It is screwed onto a screw shaft 28 that rotates in the opposite direction.

Then, the frame 24 is moved by the motor 27 at the same speed as the core material 21, and the cutter 23 is lowered by the cylinder 25, thereby cutting the core material 21 into a predetermined length.

As is clear from the above description, according to the core material manufacturing apparatus according to the present invention, the core material having foamed urethane or the like inside is produced by filling the space of a ready-made paper core with foamed urethane or the like, as in the conventional method. Since the core material can be manufactured in the same state as if it were filled with urethane foam or the like all at once, the core material can be manufactured with extremely high productivity.
