본 발명은 얇은 발포합성수지판에 과일이 삽입될 수 있는 크기로 된 다수개의 오목한 홈을 형성하여서 되는 과일포장용 받침대 또는 이와 유사한 발포합성수지제 용기류의 제조방법에 관한 것이다. 근래에는 사과나 배등의 과일을 골판지 상자내에 넣어 운반하기 위해 양호한 탄력성을 가진 발포합성수지제 과일포장용 받침대가 사용되고 있으며, 이러한 받침대는 발포합성수지판에 과일이 삽입될 수 있는 크기로 된 다수개의 오목홈(15-30개)을 형성한 구조로 되어 있다.The present invention relates to a method for manufacturing a fruit packaging pedestal or similar foamed synthetic resin container by forming a plurality of concave grooves of a size into which fruit can be inserted into a thin foamed resin sheet. In recent years, the fruit packaging base made of foamed plastic with good elasticity has been used to transport fruits such as apples and pears in a cardboard box. 15-30 pieces) are formed.

따라서 과일을 포장할 때 골판지 상자의 내부 밑면에 받침대를 깔고 각 오목홈에 과일을 끼운후 그 상방에 차례로 받침대를 깔고 과일을 끼워 포장하면 각 과일 사이에 일정한 간격이 유지되어 과일 상호간의 접촉이나 충돌로 인한 과일의 손상을 방지할 수 있으며, 상자내에 넣어진 과일을 꺼낼 때에도 받침대를 차례로 들어내면서 과일을 용이하게 꺼낼 수 있게 된다.Therefore, when packing the fruit, put a pedestal on the inner bottom of the cardboard box, insert the fruit into each recess, and then put the pedestal on top of each other and wrap the fruit in order to maintain a constant gap between the fruits. The fruit can be prevented from being damaged, and even when the fruit is taken out of the box, the fruit can be easily taken out while lifting the pedestal in turn.

상기한 바와 같은 과일포장용 받침대 또는 이와 유사한 제조하기 위한 재료로서 발포합성수지 시트(Sheet)가 사용된다. 또한 발포합성수지 시트(이하 "시트"로 약칭함)는 롤(Roll)에 감겨져 있고 성형기에서 금형으로 성형할 때 수개(4-8개)의 받침대에 해당하는 오목홈을 동시에 성형하게 되며, 따라서 시트가 성형기에서 성형되어 나온 후에도 이를 프레스기계에 올려질 수 있는 적당한 크기로 1차 절단한 후 다시 프레스기계에서 정해진 규격으로 타발하여 완제품을 얻게 된다.A foamed synthetic resin sheet is used as the material for preparing fruit packaging or the like as described above. In addition, the foamed synthetic resin sheet (hereinafter, abbreviated as "sheet") is wound on a roll and simultaneously forms concave grooves corresponding to several (4-8) pedestals when being molded into a mold in the molding machine. Even after being molded in the molding machine, the cut is first cut into a suitable size that can be placed on the press machine, and then punched to a predetermined size in the press machine to obtain a finished product.

즉, 종래에는 받침대를 제조하기 위해 시트의 성형, 1차 절단, 타발등 3단계의 공정을 거쳐야하므로 제조공정이 번거롭고 이에따라 제품의 제조원가도 높아지는 문제점이 있었다.That is, in order to manufacture the pedestal conventionally, since the three steps of forming the sheet, cutting the first, punching, etc., the manufacturing process is cumbersome and accordingly, there is a problem in that the manufacturing cost of the product increases.

본 발명의 목적은 단일공정에 의해 과일포장용 받침대와 같은 발포합성수지제 용기류를 제조할 수 있는 방법을 제공하기 위한 것으로, 이하 본 발명을 첨부된 도면에 의해 더욱 상세하게 설명하면 다음과 같다.An object of the present invention is to provide a method for producing a foamed synthetic resin container, such as a fruit packaging base by a single process, when the present invention will be described in more detail by the accompanying drawings as follows.

첨부도면 제1도는 과일포장용 받침대의 제조방법을 나타낸 본 발명 일실시예의 개략 평면도로서, 1장의 시트(1)에 다수의 오목홈(3)을 가진 4개의 받침대(2)가 성형기(6)에서 동시에 성형되어 나오는 일예를 도시한 것이다.1 is a schematic plan view of an embodiment of the present invention showing a manufacturing method of a fruit packaging stand, wherein four pedestals 2 having a plurality of concave grooves 3 in one sheet 1 are formed in the molding machine 6. It shows an example that is molded at the same time.

받침대 부분을 제외한 시트(1)의 나머지 부분(빗금친 부분)은 받침대부분보다 상방으로 돌출되도록 성형기(6)에서 금형으로 성형되며 시트(1)의 진행방향인 성형기(6)의 전면에는 열선(5)이 횡방향으로 고정되어 있다.The remaining portion (hatched portion) of the sheet 1, except for the pedestal portion, is formed into a mold in the molding machine 6 so as to protrude upwardly from the pedestal portion, and a heating wire ( 5) is fixed laterally.

이 열선(5)은 제2도와 같이, 시트(1)의 돌출부분(4)의 중간에 위치하도록 높이가 설정되어 있고, 내부에는 니크롬선등이 내장되어 일정온도로 발열을 하게 되며, 시트(1)의 전체 폭보다 긴 길이로 설치되어 있다. 따라서 시트(1)를 성형기(6)에 넣어 수개의 받침대에 해당하는 오목홈(3)을 동시에 성형한 후 시트(1)가 전방으로 밀려나오면 열선(5)에 의해 시트 돌출부분(4)이 횡방향으로 자동적으로 절단되면서 제3도와 같이 돌출턱(2a)을 가진 과일포장용 받침대(2)가 얻어진다.As shown in FIG. 2, the heating wire 5 has a height set so as to be located in the middle of the protruding portion 4 of the sheet 1, and a nichrome wire is embedded therein to generate heat at a predetermined temperature. The length is longer than the overall width. Therefore, the sheet 1 is placed in the molding machine 6, and the concave grooves 3 corresponding to several pedestals are simultaneously formed. When the sheet 1 is pushed forward, the sheet protruding portion 4 is removed by the hot wire 5. Automatically cutting in the transverse direction, a fruit packaging pedestal 2 having a protruding jaw 2a as shown in FIG. 3 is obtained.

이렇게 얻어진 과일포장용 받침대는 돌출턱(2a)에 의해 강도가 보강되므로 평면형으로 된 종래의 받침대에 비해 견고하고 골판지 상자에 넣거나 골판지 상자로부터 빼어내기가 용이해진다.Since the fruit packing stand thus obtained is reinforced by the protruding jaw 2a, the fruit packing stand is more robust than a conventional stand having a flat shape and is easily put in a cardboard box or taken out of a cardboard box.

이상에서와 같이 본 발명은 시트(1)에 돌출부분(4)을 형성하고 성형기의 전면에는 열선(5)을 설치하여 시트(1)가 성형기(6)에서 성형되어 나오면 열선(5)에 의해 돌출부분(4)이 자동적으로 절단되면서 받침대(3)의 제조가 완료되므로 받침대의 제조공정이 대폭 간소화, 자동화된다.As described above, the present invention forms the protruding portion 4 on the sheet 1 and installs the heating wire 5 on the front of the molding machine so that the sheet 1 is molded from the molding machine 6 by the heating wire 5. Since the protruding portion 4 is automatically cut, the manufacture of the pedestal 3 is completed, thus greatly simplifying and automating the manufacturing process of the pedestal.

상기 실시에에서는 성형기의 전면에 열선을 설치한 일예를 설명하였으나 열선 대신 절단칼에 의해 돌출부분을 횡방향으로 절단할 수도 있으며, 동일한 방법에 의해 과일포장용 받침대가 아닌 일반 용기류도 제조할 수 있다.In the above embodiment, an example in which a heating wire is installed on the front side of the molding machine has been described, but the protruding portion may be cut in the transverse direction by a cutting knife instead of the heating wire, and by the same method, general containers may be manufactured instead of the fruit packaging pedestal.
