Description

취출기의 인서트 불량품 선별장치 및 방법{Apparatus to sort insert inferior goods and method thereof in injection machine}Apparatus to sort insert inferior goods and method about in injection machine}

본 발명은 취출기의 인서트 불량품 선별장치 및 방법에 관한 것으로, 더욱 상세하게는 소형의 인서트물을 사출성형품에 인서트사출한 후 제대로 인서트되었는지 감지하여 양호한 사출성형품과 불량한 사출성형품을 선별하기 위한 것이다.The present invention relates to an insert rejects sorting apparatus and method of the ejector, and more particularly, to detect a good injection molded article and a poor injection molded article by detecting whether the insert is injected properly after inserting a small insert into the injection molded article.

주지하다시피, 사출기는 금형에 수지를 사출하여 자동차 범퍼, 전화기 케이스, 모니터 케이스와 같은 사출 성형품을 만드는 기기로서, 인서트물이라 불리우는 구조물을 사출 금형에 미리 삽입하고 사출 성형하여 사출성형품 내에 인서트물이 일체로 성형되게 하는 것을 인서트 사출이라 한다.As is well known, an injection molding machine is an apparatus for making injection molded products such as automobile bumpers, phone cases, and monitor cases by injecting resin into a mold, and inserting a structure called an insert into an injection mold in advance and injection molding to insert an insert into the injection molded product. Integral molding is referred to as insert injection.

이러한 인서트 사출은 부피가 큰 경우에는 작업자가 육안으로 확인하면서 인서트물을 사출 금형에 안치하고 인서트하면 되지만 크기가 매우 작은 인서트물의 경우에는 작업자가 일일이 그 위치를 확인하기 어려운 관계로 본 출원인은 크기가 매우 작은 인서트물을 취출기의 파지기구부를 통해 파지함에 있어 파지기구부 선단에 가이드핀을 형성하고, 사출금형에는 가이드핀에 대응되는 가이드홈을 형성하여 인서트물을 사출금형에 삽입할 때 가이드핀이 가이드홈에 의해 안내될 수 있게 함으로써 크기가 아무리 작은 인서트물이라하더라도 항상 정확한 위치에서 정확한 인서트가 이루어지도록 한 취출기의 인서트장치를 개시한 바 있다.In the case of a large insert, the insert may be inserted into the injection mold while the operator visually checks the insert. However, in the case of a very small insert, the applicant is difficult to check its position. When holding a very small insert through the gripping mechanism of the ejector, a guide pin is formed at the tip of the gripping mechanism, and a guide groove corresponding to the guide pin is formed in the injection mold so that the guide pin is inserted when inserting the insert into the injection mold. The insert device of the ejector has been disclosed so that the insert can be guided by the guide groove so that the correct insert is always made in the correct position, no matter how small the insert.

그러나, 상기한 취출기의 인서트장치는 기계화시스템에 의해 전자동으로 이루어지는 것이므로 사출성형품의 불량이 발생될 확률은 적지만 여러가지 원인으로 인해 크기가 매우 작은 인서트물이 사출금형에 삽입되지 않아 사출성형품에 인서트물이 인서트되지 않은 불량상태로 취출될 수도 있으며, 이럴 경우 별도의 사출성형품 선별라인에서 인력으로 선별할 수밖에 없어 많은 수의 인력이 필요한 단점이 있고, 인서트물의 크기가 매우 작아 육안으로 확인하기 곤란하여 선별작업에도 어려움이 따르게 되었다.However, since the insert device of the ejector is made of a full automatic by a mechanization system, there is a small probability that defects of the injection molded product may occur, but a very small insert is not inserted into the injection mold due to various causes. The water may be taken out in a bad state without inserting, and in this case, a large number of manpower is required because it can only be sorted by manpower in a separate injection molding product sorting line, and the insert is very small and difficult to check with the naked eye. Difficulties also come with screening.

따라서, 최근에는 불필요한 인력의 낭비를 없애고 자동으로 사출성형품의 불량여부를 판별하기 위해 중량감지장치를 사용하고 있으나, 사출성형품에 인서트되는 인서트물이 매우 작은 크기를 갖고 있어 그 중량 역시 매우 작게되므로 제대로 된 선별이 거의 불가능한 실정이다.Therefore, in recent years, a weight sensing device is used to eliminate unnecessary manpower and automatically determine whether an injection molded product is defective. However, since the insert inserted into the injection molded product has a very small size, its weight is also very small. It is almost impossible to screen selected.

본 발명은 이러한 점을 감안하여 제안된 것으로, 사출성형품에 인서트되는 인서트물을 금속재로 구성하고, 금속을 감지하는 센서를 사출성형품의 인서트물 위치와 대응되는 형상으로 지지판에 각각 설치하며, 상기 지지판을 취출기의 일측에 설치하여 파지기구부를 통해 사출성형품을 취출한 후 지지판 위치로 이동시켜 인서트물의 유무를 감지하고, 인서트물이 제대로 감지되면 사출성형품을 양품위치로 이동시키고 인서트물이 하나라도 없을 경우에는 사출성형품을 불량품위치로 이동시키는 방식으로 별도의 인력없이도 정확하게 인서트 불량을 감지하고 선별할 수 있는 취출기의 인서트 불량품 선별장치 및 방법을 제공하고자 하는 것이다.The present invention has been proposed in view of this point, and the insert is inserted into the injection-molded product made of a metal material, the sensor for detecting the metal is installed on the support plate in a shape corresponding to the position of the insert of the injection-molded product, respectively, the support plate Is installed on one side of the ejector to take out the injection-molded product through the gripping mechanism, and then moves to the position of the support plate to detect the presence or absence of the insert.If the insert is properly detected, the injection-molded product is moved to the good position. In this case, it is an object of the present invention to provide a method and apparatus for sorting insert defects of an ejector capable of accurately detecting and sorting insert defects without a separate manpower by moving an injection molded product to a defective product position.

이하, 본 발명을 제시되는 실시예에 따라 구체화한다.Hereinafter, the present invention will be embodied according to the examples presented.

본 발명에 따른 취출기의 인서트 불량품 선별장치는 도 1 및 도 2에 도시한 바와 같이 취출아암(11) 하부에 설치된 인서트물 파지기구(12)를 통해 인서트물(13)을 파지하여 사출금형(미도시)에 삽입시켜주고, 인서트물 파지기구(12)의 하부에 설치된 사출성형품 파지기구(14)를 통해 사출성형품(15)을 파지하여 취출하는 취출기(10)에 있어서, 인서트물(13)을 금속재로 구성하고, 금속만을 감지할 수 있는 센서(16)를 사출성형품(15)의 인서트물 위치와 대응되는 형상과 개수로 지지판(17)에 각각 설치하며, 지지판(17)을 취출기(10)의 일측에 설치하고, 센서(16)를 각 파지기구(12)(14)를 제어하는 중앙처리장치(미도시)와 연계 구성한 것이다.The insert defective article sorting device of the ejector according to the present invention, as shown in Figs. 1 and 2 by holding the insert (13) through the insert holding mechanism 12 installed in the lower portion of the ejection arm (11) injection molding ( In the take-out machine 10 which inserts into the insert and grips and ejects the injection-molded product 15 through the injection-molded product holding mechanism 14 installed in the lower part of the insert holding mechanism 12, the insert 13 ) Is made of a metal material, and each sensor 16 capable of detecting only metal is installed on the support plate 17 in the shape and number corresponding to the insert position of the injection molded product 15, and the support plate 17 is taken out. It is provided at one side of (10), and the sensor 16 is comprised in connection with the central processing unit (not shown) which controls each holding mechanism 12,14.

이때, 사출성형품(15)과 인서트물(13)의 종류에 따라 각 센서(16)의 개수, 배치 등이 달라지게 됨은 자명하며, 사출성형품 파지기구(14)의 이동경로 역시 달라지게 된다.At this time, it is obvious that the number, arrangement, etc. of each sensor 16 will vary according to the type of the injection molded product 15 and the insert 13, and the movement path of the injection molded product holding mechanism 14 will also vary.

도면상의 미설명 부호 18은 취출아암(11)을 상하, 좌우로 이동시키는 이동기구를 나타낸다.Reference numeral 18 in the drawing denotes a moving mechanism for moving the takeout arm 11 up and down, left and right.

이와 같이 구성된 상태에서 도 3과 같이 인서트물 파지기구(12)를 통해 인서트물(13)을 사출금형에 삽입하고, 인서트물(13)이 인서트된 사출성형품(15)은 사출성형품 파지기구(14)를 통해 파지하여 취출하게 되는데, 인서트물 파지기구(12)에는 기준핀(12a)을 형성하고, 도시하지는 않았지만 사출금형 또는 인서트물 공급다이에는 기준핀(12a)에 대응되는 가이드홈을 형성하여 인서트물(13)이 항상 정확한 위치에서 정확히 인서트되도록 함이 바람직하다.In the state configured as described above, the insert 13 is inserted into the injection mold through the insert holding mechanism 12 as shown in FIG. 3, and the injection molded product 15 into which the insert 13 is inserted is the injection molded product holding mechanism 14. It is to be taken out by gripping), the insert holding mechanism 12 to form a reference pin (12a), although not shown in the injection mold or insert supply die to form a guide groove corresponding to the reference pin (12a) It is desirable for the insert 13 to always be correctly inserted in the correct position.

사출성형품 파지기구(14)를 통해 사출성형품(15)을 취출한 후에는 취출기(10)의 일측에 설치된 각 금속감지 센서(16)의 위치로 사출성형품(15)을 이동시키게 되며, 각 센서(16)는 대상이 되는 사출성형품(15)의 인서트물 위치와 동일한 위치에 배치되어 있으므로 각 센서(16)별로 사출성형품(15)에 인서트물(13)이 존재하는지 여부를 각각 감지할 수 있다.After taking out the injection-molded product 15 through the injection-molded product holding device 14, the injection-molded product 15 is moved to the position of each metal detection sensor 16 installed on one side of the ejector 10, and each sensor 16 is disposed at the same position as the insert position of the target injection molded product 15, it is possible to detect whether the insert 13 is present in the injection molded product 15 for each sensor 16, respectively. .

이러한 감지신호는 각 센서(16)와 연계되어 있는 중앙처리장치로 자동 입력되고, 중앙처리장치에서는 기 입력되어 있는 데이터와 감지신호를 비교 연산하여 사출성형품(15)에 인서트물(13)이 모두 존재하는지 또는 그렇지 않은지 판별한 후 사출성형품(15)에 인서트물(13)이 모두 존재하는지 여부에 따라 개별적인 선별명령을 하달하게 된다.The detection signal is automatically input to the central processing unit associated with each sensor 16, and the central processing unit compares the previously input data with the detection signal to insert all the inserts 13 in the injection molded product 15. After determining whether or not it is present, the individual sorting command is issued according to whether all the inserts 13 are present in the injection-molded product 15.

즉, 사출성형품(15)에 인서트물(13)이 모두 존재하는 경우에는 사출성형품 파지기구(14)가 사출성형품(15)을 양품 배출라인으로 이송하게 되고, 사출성형품(15)에 인서트물(13)이 일부 또는 전부 존재하지 않는 경우 사출성형품 파지기구(14)가 사출성형품(15)을 불량품 배출라인으로 이송하게 되며, 이러한 사출성형품 파지기구(14)의 이동은 취출아암(11)을 상하, 전후로 이동시키는 이동기구부(18)에 의해 가능해진다.That is, when all of the inserts 13 are present in the injection molded product 15, the injection molded product holding mechanism 14 transfers the injection molded product 15 to the good discharge line, and inserts (in the injection molded product 15) 13) part or all does not exist, the injection molded product holding mechanism 14 transfers the injection molded product 15 to the defective product discharge line, the movement of this injection molded holding device 14 is moved up and down the ejection arm (11) This is enabled by the moving mechanism unit 18 moving back and forth.

따라서, 인서트물(13)이 불량하게 인서트된 사출성형품(15)은 폐기하거나 재생과정을 거쳐 다시 사출성형에 사용할 수 있으며, 인서트물(13)이 양호하게 인서트된 사출성형품(15)은 곧바로 다른 부품과의 조립과정에 투입할 수 있어 작업성을 높일 수 있는 것이다.Therefore, the injection molded product 15 into which the insert 13 is badly inserted can be used again for injection molding after being discarded or regenerated, and the injection molded product 15 into which the insert 13 is well inserted is immediately replaced with another. It can be put into the assembly process with parts, thereby improving workability.

이상에서 설명한 바와 같이, 본 발명은 소형사이즈의 인서트물이 인서트된 사출성형품을 최종 취출할 때 각 인서트물의 위치와 동일하게 배치되어 있는 금속감지센서로 이동시켜 이로부터 사출성형품에 인서트물이 모두 존재하는지 여부를 감지하여 양품 또는 불량품 라인으로 각각 배출하는 것이므로 별도의 인력이나 중량감지장치없이도 항상 정확한 선별이 가능해져 제품의 신뢰성을 향상시킬 수 있음은 물론 인건비 지출 및 설비에 소요되는 비용을 최소화할 수 있고, 양품라인으로부터 배출된 사출성형품을 가지고 곧바로 후공정에 착수할 수 있어 작업성을 크게 향상시킬 수 있는 매우 유용한 효과가 있는 것이다.As described above, in the present invention, when the injection molded article inserted into the small-sized insert is finally taken out, it moves to the metal detection sensor arranged in the same position as each insert, whereby all the inserts exist in the injection molded article. It detects whether the product is discharged to the good or defective line, so that accurate screening is always possible without the need for a separate manpower or weight sensor, thereby improving the reliability of the product and minimizing the labor cost and equipment cost.
