Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to panels for use as wall materials for refrigerators, partition materials, roofing materials, building materials such as boards, etc., and particularly relates to such panels. It relates to a method and apparatus for manufacturing.

[Prior Art] There are types of panels used as wall materials for refrigerators, building materials, etc. as shown in FIG. This panel 1 has a core material 2 made of a foamable material such as foamed resin or foamed concrete, and a surface material 3 made of a thin sheet such as glass fiber, nonwoven fabric, aluminum foil sheet, or paper sheet bonded to the surface of the core material 2 made of a foamable material such as foamed resin or foamed concrete. It is configured. In addition, in order to improve the bond between the surface material 3 and the core material 2 and to increase the strength of the panel 1, a thin tape 4 combined with a honeycomb structure is adhered to the inner surface of the surface material 3. .

Conventionally, when manufacturing such a panel 1, a so-called batch method was used. That is, a thin sheet cut in advance to the size of the surface material 3 when the panel is completed is prepared, a thin tape 4 having a honeycomb structure is adhered to one side of the thin sheet, and then two thin sheets are attached to the thin tape 4. are arranged parallel to each other so as to face each other at a predetermined interval, and a foaming material is filled between the two.

[Problems to be Solved by the Invention] However, the conventional batch-type panel manufacturing method described above has the problem of being very time-consuming and poor in productivity.

SUMMARY OF THE INVENTION An object of the present invention is to provide a continuous panel manufacturing method and apparatus in order to solve such problems.

[Means for Solving the Problems] A panel manufacturing method according to the present invention involves feeding out two thin sheets, an upper and a lower sheet, made of glass fiber, metal foil, etc., facing each other, and removing the lower surface of the upper thin sheet and the lower surface of the lower thin sheet. Apply adhesive to the top surface, roll out multiple thin tapes made of paper, metal foil, etc. in parallel to each other, and adhere one edge of the tape to the adhesive-coated surface of each thin sheet in a serpentine pattern. It is characterized by filling the space between thin sheets with a foamable material, solidifying it, and cutting it into predetermined dimensions.

The panel manufacturing apparatus according to the present invention also includes a thin sheet feeding means for feeding out two thin sheets, upper and lower, made of glass fiber, metal foil, etc., facing each other, and a lower surface of the upper thin sheet and a lower thin sheet. An adhesive application means for applying adhesive to the top surface of the sheet, a thin tape made of paper or metal foil, etc., which is fed out in a horizontally adjustable manner, and one edge of the tape is adhered to the adhesive-coated surface of the thin sheet. a plurality of thin tape adhesion means for attaching a plurality of thin tapes, a foaming material filling/solidifying means for filling and solidifying a foaming material between the upper and lower thin sheets, and a cutting means for cutting out a panel of predetermined dimensions. It is characterized by

[Embodiments] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 schematically shows an example of a panel manufacturing apparatus according to the present invention. Two thin sheet coils 11 are arranged at the most upstream side of the production line in the illustrated panel manufacturing apparatus 10, and from these coils 11 thin sheets (glass fiber, non-woven fabric, aluminum, Foil sheets, paper sheets, etc.) 12 are unwound vertically facing each other and sent to the corresponding molding devices 13, respectively. These forming devices 13 are composed of a plurality of rollers 14, and when the thin sheet 12 passes through these rollers, rising edge portions, surface irregularities, etc. are formed.

After passing through the forming device 13, an adhesive is applied to the lower surface of the upper thin sheet 12 and the upper surface of the lower thin sheet 12 by an adhesive applying device 15, respectively. Then, one edge of the thin tape (paper, other metal foil, etc.) 17 is adhered at right angles to the adhesive coated surface formed on each thin sheet 12 by the corresponding thin tape adhesive device 16. Ru.

Various types of thin tape bonding device 16 may be considered that can be applied to the present invention, but for example, as shown in FIG. 2, a feeding mechanism 19 that feeds out thin tape 17 from a thin tape coil 18;
It consists of a guide roller 20 that is swung left and right by a crank mechanism (not shown) to change the feeding position of the thin tape 17.
The thin tape 17 can be adhered to the adhesive-applied surface of the thin sheet 12 in a meandering manner by sending it out according to the left-right reciprocating movement of the guide roller 20. still,
In order to ensure perfect adhesion between the thin tape 17 and the thin sheet 12, it is preferable to provide a hot pressure roll 20 downstream of the thin tape bonding device 16, which applies heat and pressure to both.

A necessary number of such thin tape bonding devices 16 are arranged in the horizontal direction of the production line, and by controlling the adjacent thin tape bonding devices 16 so that the apexes of adjacent thin tapes 17 touch each other, the thin tapes 17 are A honeycomb structure is formed as shown in FIG.

Upper and lower thin sheets 12 to which thin tape 17 is adhered
is progressed along the production line. Then, in the foaming chamber 23, a foamable material 24 such as foamed resin or foamed concrete is filled and foamed into the upper and lower thin sheets 12 by a foamable material filling device 25. Thereafter, the upper and lower thin sheets 12 are arranged at predetermined intervals and sent to the after-cure heating device 26.
The foamable material 24 is solidified in the after-cure heating device 26, and the thin sheet 12 and the thin tape 1 are
7, and finally cut into a predetermined size by a cutting device 27. In this way, the thin sheet 12
A panel 28 (equivalent to the panel 1 shown in FIG. 3) is composed of a surface material made of a foam material 25, a core material made of a foamed material 25, and a thin honeycomb-structured tape 17 that adheres to the surface material and the core material. Once completed, it will then be sent to the transport line as appropriate.

Although one embodiment of the present invention has been described above,
Various modifications can be made without departing from the scope of the invention. For example, by changing the timing of the swing of the guide roller 20 of each thin tape bonding device 16, as shown in FIG.
Panel 3 configured such that 7 are spaced apart from each other.
You can also create 0. In addition, by controlling the feeding speed of the thin tape 17, the swing width of the guide roller 20, etc., the thin tape 17 can be shaped into the thin sheet 1 in various ways.
It can be glued to 7.

Furthermore, by operating only one of the upper and lower thin tape bonding devices 16, it is possible to form a panel (not shown) in which the thin tape 17 is attached only to one side of the surface material.

[Effects of the Invention] As described above, according to the present invention, panels can be manufactured continuously, so there is no interruption in the process unlike in the batch method, and the effect of improving operating efficiency and productivity is It is enormous.

Furthermore, by controlling various operations of the thin tape bonding device (thin tape bonding means) in the panel manufacturing apparatus according to the present invention, the arrangement structure of the thin tape can be changed in various ways including a honeycomb structure, and panels with different special features can be created. It can be easily manufactured.
