The present invention relates to a sandwich panel manufacturing apparatus, and more particularly to a system for manufacturing a sandwich panel for interior and exterior materials used for door trim or headlining for automobiles.

In general, a sandwich panel is a structural material that is realized by high-pressure bonding of two or more material materials having different characteristics, and is currently widely used in industries including the automobile industry and construction. In particular, sandwich panels used in automobile door trims, headlinings, and the like are formed by bonding a skin material for reinforcing surface strength to at least one surface of an intermediate material having a plate shape, and manufacturing such a sandwich panel for interior / exterior materials. Manufacturing apparatus for has a configuration as shown in Figures 1a and 2b.

In this case, Figure 1a is a plan view showing a typical sandwich panel manufacturing apparatus, Figure 1b is a side view.

A general production system for interior / exterior sandwich panels includes: a mounting table 3 for storing the skin material 1; Piston rod which can be lifted and lowered by means such as air cylinder 4, and has a plurality of suction clamps 5 at its ends to take out the skin 1 stored inside the mounting table 3 to the outside. (6); A heating device (C) for heating the skin material; A high pressure molding apparatus (D) for accommodating the intermediate material provided in the other process and the skin material heated in the heating device and bonding them at high pressure; A pair of guide rails 10 extending through the heating apparatus C to the high pressure molding apparatus so that the skin material can be transferred from the mounting table 3 to the high pressure molding apparatus D through the heating apparatus C. ) And a transfer part (b) including a pallet 13 which moves the skin material transferred from the piston rod 6 and moves the guide rail in a sliding manner.

Will be moved to.

On the other hand, in the high pressure molding apparatus (D), which receives the heated skin material through this process, an intermediate material (not shown), which is pre-introduced by manual or other processes, is located, and is heated on one surface of the intermediate material. When the skin is placed, the two are bonded together at high pressure.

However, in a general sandwich panel manufacturing system for interior and exterior materials, the transfer device (b) to which the skin material is transferred, the heating device for heating it (c), and the high pressure molding device (d) each use only one skin material in one process. It has a disadvantage that it is difficult to be used when bonding the skin material on both sides of the intermediate material, and the single pallet 13 reciprocates the skin material from the loading table to the molding apparatus. The use of the transfer method has the disadvantage that the process time is longer as much as the return time to the initial position of the pallet.

That is, in manufacturing a sandwich panel through a general manufacturing apparatus, the skin material is sequentially removed from the loading table and moved to the heating device and the high pressure molding device while being seated on the pallet, and then the skin material to be treated is the pallet high pressure molding device. Wait until the return from the, and also because the return time of the pallet can not be shortened to a certain degree, there is a problem that the work time is delayed.

The present invention has been made to solve the above problems, it is possible to attach the skin material on both sides of the intermediate material, it is possible to provide a more improved sandwich panel manufacturing apparatus capable of shortening the process time. have.
