Description

DETAILED DESCRIPTION OF THE INVENTION This article relates to a method of manufacturing a core panel.

A honeycomb core panel as shown in Fig. 1 is manufactured as a wall panel, etc. In the figure, 1 is a panel frame into which a honeycomb core 2 is inserted, and a surface plate 3 is provided on both sides.
is stretched. The surface plate 3ζ and Ni1 are bonded to the panel frame 1 and the honeycomb core 2 with adhesive. The honeycomb core 2 is of paper I impregnated with resin.

When manufacturing such a honeycomb core panel, conventionally, a liquid adhesive was applied to the back surface of the top plate 3 and then an adhesive was applied. and was adhered to honeycomb core 2. However, the end surfaces of each partition wall of the honeycomb core 2 were thin, and most of the adhesive applied to the back surface of the top plate 3 was wasted.

Therefore, an object of the present invention is to provide a method for manufacturing a honeycomb core panel that allows reliable adhesion of honeycomb cores without wasting adhesive.

An embodiment of this invention is shown in FIGS. 2 and 3. First, the order making device will be explained. In this case, 4 is a conveyor on which the honeycomb core 2 is placed and conveyed, and a liquid adhesive application device 5 is provided on the conveyor route.

Powder adhesive application devices 6 are provided in order from the upper side. A collection hopper 7 is provided below the powder adhesive application device P<6. Liquid adhesive applicator fF'l
5 ij: The application belt 8 of the nozzle M on which the liquid adhesive is impregnated and applied, the adhesive f99, and the bottom of this adhesive tank 9"lj
゛, is provided at i to supply adhesive to the applicator belt 8 (
The powder adhesive application device 6 includes a dispersing tube 11 that is provided along the conveyance direction of the conveyor 4 and rotates around a horizontal axis, Powder striking: Consists of a supply hopper 12 for supplying adhesive.The dispersion tube 11 has a large number of small holes on its circumferential surface.

Next, the manufacturing method will be explained. The honeycomb core 2 is conveyed to a conveyor 4-, and a liquid adhesive 1')7 is applied to the upper end surface of each partition wall 2a by a cloth device 115;
Qi 113 is applied 1. Ru. Then, when passing through the powder adhesive applicator 1-6, lj,i,, cloth cylinder 1
The powder adhesion 1j;'7 neck 1j14 spread from 1 to 1 adheres to the upper end surface of the partition 4a 2a of the core 2 due to the liquid adhesion 1]13.

This process is repeated f'd times three times, and as shown in FIG. 3, the required amount of the adhesive layer 1113 and the powder adhesive 14 are applied to the upper end surface of the partition wall 2a of the honeycomb core 2. Ensure adhesive elasticity. This honeycomb core 2 is turned over, and lfe-like adhesive/1113 yen and powder adhesive 14 are applied to the upper end surface of the partition wall 2a of the honeycomb core 2. After this,
Insert the honeycomb core 2 into the panel frame 1 as shown in Figure 1,
Top plate 3 is stacked on top and hot pressed. As a result, the surface plate 3 is hardened and bonded to the end face of each partition wall 2a of the honeycomb core 2 with the liquid adhesive 13 and the powder adhesive 14.
The surface plate 3 may be joined to the panel frame 1 at the same time during this hot pressing, or other joining methods may be used.

In this way, the honeycomb core panel is queried, but before adhesion 1113 to the end face of each partition wall 2a of the honeycomb core 2,
14, there is no waste compared to the conventional case where adhesive is applied to the back surface of the surface plate 3, and the amount of adhesive used can be reduced significantly. Moreover, since the liquid adhesive 1113 is applied and the powder adhesive 14 is adhered thereon, sufficient adhesive 13 is applied even if the end face of the partition wall 2a of the honeycomb core 2 is small. A coating amount of .14 was applied to ensure adhesive elasticity.

Incidentally, in the above embodiment, the adhesives 13 and 14 were applied to both the upper and lower surfaces of the honeycomb core 2.
