본 발명은 합성수지 성형기의 공기제거장치에 관한 것으로, 더욱 상세하게는 압출기에 있어, 합성수지성형기에서 성형중에 원료를 제습하여 균일한 원료공급과 규격화된 고품질 제품생산이 이루어지도록함은 물론 이에따른 작업생산성 및 소비전력절감과 원료절감 효과를 기대할 수 있는 합성수지 성형기의 공기제거장치에 관한 것이다.The present invention relates to an air removing device of a synthetic resin molding machine, and more particularly, in an extruder, dehumidifying the raw materials during molding in a synthetic resin molding machine to achieve uniform raw material supply and standardized high-quality product production, as well as work productivity accordingly. And an air removing device of a synthetic resin molding machine capable of reducing power consumption and reducing raw materials.

일반적으로, 열경화성, 열가소성합성수지를 이용하여 필름, 시이트, 발포제품 및 그밖의 사출물 등을 성형하는 성형기는 성형방식에 따른 분류로서 사출기와 압출기가 범용되고 있는바,In general, a molding machine for molding a film, a sheet, a foamed product, and other injection molding products using a thermosetting thermoplastic resin is classified according to a molding method, and injection molding machines and extruders are generally used.

이와같은 압출기(100)와 사출기(200)는 호퍼(110,210)로부터 공급되는 원료 및 각종 첨가재료를 혼합통(120,220)내에서 믹싱하는 단계까지 동일하나, 그 이후 도 1 a와 압출다이(130)를 통해 압출성형하는 것을 압출기(100)라 하며, 도 1 b에서와 같이 사출램(230)으로 금형속에 넣고 플렌저로 압입하는 것이 사출기(200)라 한다.The extruder 100 and the injection machine 200 are the same until mixing the raw materials and various additive materials supplied from the hoppers 110 and 210 in the mixing cylinders 120 and 220, but thereafter, FIG. 1A and the extrusion die 130 Extruded through the extrusion is called an extruder 100, and as shown in Figure 1 b is put into the mold with an injection ram 230 and press-fitted into a flanger is called an injection machine (200).

여기서, 상기 호퍼(110,210)를 통해 공급되는 수지원료는 혼합통(120,220)에서 가열,연화됨과 동시에 스크류 등에 의해 유동화되어 금형 또는 압출다이로 이송이 이루어지게 된다.Here, the water support material supplied through the hoppers 110 and 210 is heated and softened in the mixing cylinders 120 and 220 and fluidized by a screw or the like and transferred to a mold or an extrusion die.

따라서 종래의 구성으로 이루어지는 압출기(100)나 사출기(200)는 습한공기가 혼합되어 원료와 함께 이송되어 성형기내부에 존재하게 되므로써, 이송수단인 스크류 등에 부하로 작용하는 등 합성수지원료의 공급이 불균일하게 이루어지는 요인으로 작용하게 된다.이로인해 제품에 구멍(pin hole)이 형성되거나 제품의 투명성이 저하되며 그만큼 제품의 불량율이 증가됨에 따라, 결과적으로 볼때 작업생산성의 저하와 함께 과부하에 의한 불필요한 전력손실 및 원료가 낭비되는 문제점을 갖는 것이었다.Therefore, the extruder 100 or the injection machine 200 having a conventional configuration is mixed with the humid air and transferred together with the raw material to be present in the molding machine. As a result, pin holes are formed in the product or transparency of the product is reduced and the defective rate of the product is increased accordingly, resulting in unnecessary work loss and unnecessary power loss due to overload. The problem was that the raw material was wasted.

따라서, 본 발명은 전술한 종래의 문제점을 해결하기 위한 것으로,Therefore, the present invention is to solve the above-mentioned conventional problems,

<실시예><Example>

본 발명에 따른 합성수지 성형기의 일예인 압출기에 적용된 공기제거장치의 실시예를 나타내는 것으로서, 호퍼(7)로부터 공급된 수지원료(9)를 가열, 연화시키는 혼합통(6)에서 이동시키는 1차 이송스크류(61)와 배출되는 출구(62)로 이루어져 있다.상기 수지원료(9)가 배출되는 출구(62)에는 수지원료(9)의 배출량을 조절하기 위하여 공압실린더(31)에 의하여 작동하는 피스톤(33)과 피스톤에 의하여 수평작동되는 개폐봉(34)과 수지원료(9)가 적정하게 공급되도록 하는 용량감지센서(32)로 구성되는 조절부(3)가 흡입실(21)에 내설되어 있다.상기 흡입실(21)을 거친 수지원료(9)는 압출다이(8)로 이동시키는 2차 이송스크류(81)의 선단부에 구성되어 2차배출작용을 행하는 2차 배출부(4)로 구성된다.An embodiment of an air removing device applied to an extruder which is an example of a synthetic resin molding machine according to the present invention, the first transfer to move in the mixing vessel (6) for heating and softening the water support material (9) supplied from the hopper (7) A screw 61 and an outlet 62 are discharged. The outlet 62 through which the water support fee 9 is discharged is operated by a pneumatic cylinder 31 to control the discharge of the water support fee 9. (33) and the adjusting section (3) consisting of a capacitive sensor (32) to properly supply the opening and closing rod 34 and the water support material (9) horizontally operated by the piston is built in the suction chamber 21 The water support material 9 which has passed through the suction chamber 21 is configured as a front end portion of the secondary transfer screw 81 for moving to the extrusion die 8 to the secondary discharge portion 4 which performs the secondary discharge action. It is composed.

상기 혼합통(6)에서는 통상의 압출기와 같이 호퍼(7)에서 공급되는 분말(POWDER) 또는 칩형태의 수지원료를 1차 이송스크류(61)에 의해 이송시키며 가열,연화하여 반죽상태로 만들게 되는데,In the mixing barrel (6), like a conventional extruder, the powder (POWDER) or chip-shaped water supplied from the hopper (7) is transferred by the primary transfer screw (61) and heated, softened to make a dough state. ,

이와같은 혼합통(6)의 출구(62)에는 도 3에서와 같이 밀폐구조의 직사각체형상을 취하는 흡입실(21)을 구성한다.At the outlet 62 of such a mixing cylinder 6, as shown in FIG. 3, the suction chamber 21 which takes the rectangular shape of a sealed structure is comprised.

이때, 상기 흡입실(21)은 도 2 내지 도 3에서와 같이 상부측으로 진공모터(5)와 연결되는 1차 배출관(211)을 관연결되도록 외부와 연통되는 1차 배출공(H)을 형성하고, 중앙에는 전술한 조절부(3)가 구성되며, 하부는 압출다이(8)로 수지원료(9)를 공급하기 위해 압출다이(8)의 2차이송스크류(81) 선단부 상부측에 연통설치되는 공급구(212)가 형성한다.At this time, the suction chamber 21 forms a primary discharge hole (H) in communication with the outside to connect the primary discharge pipe 211 connected to the vacuum motor 5 to the upper side as shown in Figures 2 to 3. In the center, the above-described adjustment part 3 is configured, and the lower part communicates with the upper end of the secondary feed screw 81 of the extrusion die 8 to supply the water support material 9 to the extrusion die 8. Supply port 212 is installed is formed.

또한, 상기 조절부(3)는 도 3에서와 같이 혼합통(6)의 출구(62)를 개폐할 수 있도록 원통형체를 취하는 개폐봉(34)이 외부 공압라인과 연결된 공압실린더(31)에 의해 수평작동을 행하도록 구성되는 것인데,In addition, the adjuster 3 is an opening and closing rod 34 taking the cylindrical body to open and close the outlet 62 of the mixing cylinder 6 as shown in Figure 3 to the pneumatic cylinder 31 connected to the external pneumatic line It is configured to perform horizontal operation by

이와같이 개폐봉(34)이 피스톤상에 연결되는 공압실린더(31)는, 도 3에서와 같이 혼합통(6)의 출구(62)와 흡입실(21)의 연결부위로 설치되는 용량감지센서(32)의 전기적신호에 의해 작동되며, 이러한 용량감지센서(32)는 혼합통(6)에서 공급되는 수지원료(9)의 공급량을 감지하여 과잉공급(혼합통의 출구보다 높은 용량으로 공급되는 것)되는 것을 방지하게 된다.In this way, the pneumatic cylinder 31, in which the opening and closing rod 34 is connected to the piston, has a capacity detecting sensor installed at a connection portion between the outlet 62 of the mixing cylinder 6 and the suction chamber 21 as shown in FIG. 32, which is operated by an electrical signal, and the capacitive sensor 32 detects the supply amount of the water support fee 9 supplied from the mixing vessel 6 and supplies the oversupply (capacity higher than the outlet of the mixing vessel). Will be prevented).

여기서, 상기한 개폐봉(34)은 혼합통(6)의 출구(62)를 개폐작업할때에 도 3에서와 같이 혼합통(6)의 출구(62)외둘레에 밀착되어 밀폐하도록 ""와 같은 형태로 구성함이 바람직하다.Here, the opening and closing bar 34 is in close contact with the outer circumference of the outlet 62 of the mixing cylinder 6, as shown in FIG. It is preferable to configure in the form of ".

한편, 2차 배출부(4)는 전술한 흡입실(21)의 공급구(212)와 연결되어, 공급되는 원료를 압출다이(8)로 이송하는 2차이송스크류(81)를 내설한 원통형케이스(82)에 상,하,좌,우에 2차흡입공(H')을 형성하여 전술한 외부 진공모터(5)와 연결된 2차배출관(41)을 관연결하여 구성한다.On the other hand, the secondary discharge portion 4 is connected to the supply port 212 of the suction chamber 21 described above, the cylindrical shape of the secondary feed screw 81 for transferring the supplied raw material to the extrusion die (8) Secondary suction holes (H ') are formed in the case 82 in the upper, lower, left, and right sides to connect the secondary discharge pipes 41 connected to the external vacuum motor 5 described above.

이와같이 2차 배출부(4)가 2차 이송스크류(81)의 선단부측에 위치구성하는 것은, 선단부측에 공극이 가장 크게 형성되므로 2차배출관(41)을 통한 공기제거가 용이하며, 수지원료가 2차배출관(41)에 유입되는 것을 방지하도록 하는 것이다.As such, the secondary discharge part 4 is positioned at the tip end side of the secondary feed screw 81, so that the air gap is formed on the tip end side with the largest gap, so that air can be easily removed through the secondary discharge pipe 41, Is to prevent the flow into the secondary discharge pipe (41).

이에, 상기와 같은 구성을 갖는 본 발명의 합성수지성형기(1)는 혼합통(6) 및 압출다이(8)에 존재하는 대기중의 습기와 공기를 외부로 배출하여, 혼합통(6)에서 공급되는 연화된 수지원료(9)와 습기와 공기를 분리함과 동시에 합성수지성형기(1)내부가 진공상태를 유지하도록 작동하게 된다.Thus, the synthetic resin molding machine 1 of the present invention having the configuration as described above discharges the moisture and air in the air present in the mixing cylinder 6 and the extrusion die 8 to the outside, and is supplied from the mixing cylinder 6 The soft water support material 9 is separated from moisture and air, and at the same time, the inside of the synthetic resin molding machine 1 operates to maintain a vacuum state.

도 4에서 나타내는 바와 같이, 혼합통(6)을 거쳐 출구(62)를 통해 연화된 수지원료(9)가 흡입실(21)로 공급되면, 수지원료(9)와 함께 흡입실(21)로 유입되는 대기중의 습기와 공기는 흡입실(21)의 상부측에 위치하는 1차 배출관(211)을 통해 1차적으로 흡입실(21)의 외부로 배출되고,As shown in FIG. 4, when the softened water support material 9 is supplied to the suction chamber 21 through the outlet 62 through the mixing cylinder 6, the water support material 9 is supplied to the suction chamber 21 together with the water support material 9. Moisture and air in the incoming air is first discharged to the outside of the suction chamber 21 through the primary discharge pipe 211 located on the upper side of the suction chamber 21,

이후, 흡입실(21)의 공급구(121)를 통해 수지원료(9)가 공급되면 2차 이송스크류(81)의 후미측 사방으로 구성되는 2차배출관(41)을 통해 계속적인 내부공기의 배출작용이 이루어지게 된다.Subsequently, when the water support fee 9 is supplied through the supply port 121 of the suction chamber 21, the internal air is continuously supplied through the secondary discharge pipe 41 formed of the rear sides of the secondary transfer screw 81. Ejection is achieved.

이때, 용량감지센서(32)는 흡입실(21)로 공급되는 수지원료(9)가 과잉공급되어 혼합통(6)의 출구(62)보다 높은 적층량을 갖게 될 경우, 이를 사전에 감지하여 그 감지값을 공압실린더(31)로 보내게 되고, 이러한 전기적 신호에 의해 공압실린더(31)의 피스톤(33)이 전개작동되어 피스톤(33)에 연결된 개폐봉(34)이 혼합통(6)의 출구(62)를 막게 되므로 더이상의 수지원료(9)의 공급을 차단하게 된다.At this time, the capacity detecting sensor 32 detects this in advance when the water support charge 9 supplied to the suction chamber 21 is oversupplied to have a stacking amount higher than that of the outlet 62 of the mixing cylinder 6. The detection value is sent to the pneumatic cylinder 31, and the piston 33 of the pneumatic cylinder 31 is expanded and operated by the electrical signal, and the opening and closing rod 34 connected to the piston 33 is mixed with the mixing cylinder 6 Since the outlet 62 is blocked, the supply of the additional support fee 9 is cut off.

상기와 같이 수지원료(9)의 공급을 차단함에 따라 흡입실(21)내 원료용량이 감소되면, 이와같은 용량변화를 용량감지센서(32)에 의해 감지하여 전술한 개폐봉(34)작동을 역순으로 행하게 되므로 수지원료(9)의 공급이 재개되는 것이며, 상기와 같은 개폐봉(34)의 개폐작동을 반복하면서 적정량의 수지원료(9)를 압출다이(8)로 공급할 수 있음은 물론 흡입실(21)에서의 계속적으로 습기와 공기를 제거하는 작동을 행할 수 있는 것이다.When the raw material capacity in the suction chamber 21 is reduced by cutting off the supply of the water support fee 9 as described above, the capacity change sensor 32 detects such a change in capacity to operate the opening and closing rod 34 described above. Since it is performed in the reverse order, the supply of the water support fee 9 is resumed, and the proper amount of the water support fee 9 can be supplied to the extrusion die 8 while repeating the opening and closing operation of the opening / closing rod 34 as described above. This operation can continuously remove moisture and air from the seal 21.

이에 따라, 수지원료(9)는 습한공기와 완전분리된 상태로 압출다이(8)를 통해 압출성형되므로 균일한 수지원료공급에 따른 규격화된 고품질제품생산을 구현할 수 있게 된다.Accordingly, since the water support material 9 is extruded through the extrusion die 8 in a completely separated state from the wet air, it is possible to realize a standardized high quality product production according to the uniform water supply material supply.

또한, 위와같이 습기와 공기를 제거한 상태로 공급되는 수지원료(9)의 압출성형은 수지원료(9)의 온도를 일정하게 유지할 수 있으며, 2차 이송스크류(81) 등의 과부하를 방지할 수 있어, 그만큼 고품질제품을 생산할 수 있음은 물론 작업생산성의 향상할 수 있는 파생효과를 갖게된다.In addition, the extrusion molding of the support material (9) supplied in a state of removing moisture and air as described above can maintain a constant temperature of the support material (9), it can prevent the overload of the secondary transfer screw (81) and the like. Therefore, the high quality product can be produced as well as the derivative effect of improving the work productivity.

한편, 상기와 같이 실시예로서 압출기를 적용하여 설명한 본 발명의 합성수지성형기의 공기제거장치는 압출기뿐만아니라 사출기의 혼합통과 이송스크류의 사이에 구성하면 동일한 작용,효과를 얻을 수 있는 것이다.On the other hand, the air removing device of the synthetic resin molding machine of the present invention described by applying the extruder as an embodiment as described above, if the configuration between the extruder as well as the mixing cylinder and the transfer screw of the injection molding machine can achieve the same effect.
