Abstract

PURPOSE:To easily joint corrugated cardboards made of resin by a method wherein a plurality of corrugated cardboards made of thermoplastic resin are placed to be superimposed on a pressure receiving stand, and a vibrator of a ultrasonic heating welder is brought into pressure welding with the top surface from above. CONSTITUTION:Corrugated cardboards each made of thermoplastic resin such as polyethylene or polypropyrene and having a structure consisted of an upper sheet 2a, a lower sheet 3a and partitions 4a, 5a disposed therebetween as cores, are jointed to each other. For this purpose, those corrugated cardboards are placed to be superimposed on a pressure receiving stand 9, and a vibrator 8 of a ultrasonic heating welder is pushed against the top surface from above, so that the vibrator penetrates into the corrugated cardboards while softening and melting them. Next, the vibrator 8 is lifted up after forming the softened and molten part of the resin connecting the upper sheet 2a of the upper corrugated cardboard 1 with a lower sheet 3a of the lower corrugated cardboard 7, and then the softened and molten part is hardened.

包装物の表面に傷がつきやすかった。Corrugated poles made of thermoplastic resins such as polypropylene and polyethylene (hereinafter simply referred to as cardboard) have come to be widely used as packaging materials because of their superior durability and water resistance. When assembling returnable boxes, partitions, etc. using these steps, it is difficult to adhere them with adhesive, so the assembly is generally performed using a wire stitcher. However, when trying to remelt and recycle this assembly, it is difficult to recycle because of the metal wire stitching, and it is often unavoidable to dispose of it by incineration or landfill, and it is difficult to dispose of it. It was also unfavorable in terms of resource conservation. Furthermore, the surface of the packaged item was easily damaged by the metal wire stitching.

It is something.

以下図面によりこの発明の一実施例を説明する。An embodiment of the present invention will be described below with reference to the drawings.

振動子、９は平板状の受圧台である。In the figure, l is a cardboard made of thermoplastic resin such as polyethylene or polypropylene, with an upper sheet 2a and a lower sheet a.
A core material consisting of gaps g4a and 5a is disposed between the gaps g4a and 5a. The partition wall 4a is integrally provided vertically on the lower surface of the upper sheet 2a,
The partition walls 5a are integrally erected on the upper surface of the lower sheet 3b, and the large number of parallel partition walls 4a and the large number of parallel partition walls 5a disposed diagonally intersecting these partition walls cover the entire thickness of the corrugated pole 1. Near the center of the corrugated paperboard 1, the leading edge portions are joined to each other at a number of intersection points 6 in a mesh pattern to form a single corrugated board 1. The lower corrugated board 7 has the same structure as the corrugated board 1, and corresponding parts are shown with numerals attached. Note that the cardboard boxes 1 and 7 may be different ends of a single cardboard box, or may be two separate cardboard boxes. Further, 8 is a vibrator of the ultrasonic heating welding device, and 9 is a flat pressure receiving table.

る。Next, in order to join the corrugated poles by the method of the present invention, first, as shown in FIG. Pressure is applied to the bonded portion of the cardboard by applying sonic vibration. By absorbing the ultrasonic energy emitted by the transducer 8, each part of the cardboard boxes 1 and 7 directly below the transducer locally softens and melts, and as a result, the transducer 8
enters the cardboard. Each partition wall softens and buckles, and as shown in FIG. When the softened and fused parts 10 of 1 and 7 reach a state where they are connected, the vibrator 8 is pulled up and removed from the cardboard and left to cool. The bonding is now complete.

で詳細な説明は省略する。FIG. 3 shows another embodiment of the present invention, in which the pressure receiving table 9
The only difference from the embodiment shown in FIG. 1 is that a convex portion 11 facing the vibrator 8 is formed in the embodiment shown in FIG. 3(b).
As shown in FIG. 1, a concave portion is also formed on the lower surface of the lower corrugated board 7, and a softened and melted portion 10 is formed before the corrugated boards are overlapped and surfaced, but the joining procedure is the same as the embodiment shown in FIG. Therefore, detailed explanation will be omitted.
