도시된 바와 같이 원료통(40)으로부터 원료를 펌핑하기 위한 펌프(50)가 구비되어 있고, 상기 펌프(50)의 토출구측 원료공급관로(52)상에는 서비스탱크(60) 및 작업탱크(70)가 각각 병렬로 연결되어 있고, 상기 작업탱크(70)와 발포성형기 (200)는 원료공급관로(72)와 회수관로(74)를 통해 연결되어 있다.A pump 50 for pumping the raw material from the raw material container 40 is provided as shown, and the service tank 60 and the working tank 70 on the discharge port side raw material supply pipe 52 of the pump 50. Are respectively connected in parallel, the working tank 70 and the foam molding machine 200 is connected through the raw material supply pipe 72 and the recovery pipe (74).

상기 원료공급관로(52)상의 병렬 분기점에는 펌프(50)에서 토출된 원료를 서비스탱크(60) 또는 작업탱크(70)중 어느 하나에 택일적으로 공급하기 위한 전자식 3방밸브(80)가 설치되어 있다.At the parallel branch point on the raw material supply pipe 52, an electronic three-way valve 80 for supplying raw materials discharged from the pump 50 to either the service tank 60 or the working tank 70 is installed. It is.

상기 서비스탱크(60)내에는 서비스탱크(60)내의 원료수위를 검출하여 하한 수위일 때 상기 펌프(50)를 구동시킴과 동시에 상기 전자식 3방밸브(80)를 동작시켜 작업탱크(70)로의 유로를 차단하고, 상한 수위일 때 펌프(50)의 작동을 정지시키는 서비스탱크 원료감지센서(90)가 설치되어 있다.The service tank 60 detects the raw water level in the service tank 60, drives the pump 50 when the water level is at the lower limit, and operates the electronic three-way valve 80 to the working tank 70. The service tank raw material detection sensor 90 is provided to block the flow path and stop the operation of the pump 50 at the upper limit level.

또, 상기 작업탱크(70)에는 상기 작업탱크(70)내의 원료수위를 검출하여 하한 수위일 때 상기 펌프(50)를 구동시킴과 동시에 상기 전자식 3방밸브(80)를 동작시켜 서비스탱크(60)로의 유로를 차단하고, 상한 수위일 때 펌프(50)의 작동을 정지시키는 작업탱크 원료감지센서(100)가 구비되어 있다.In addition, the working tank 70 detects the raw water level in the working tank 70 and drives the pump 50 when the water level is at the lower limit, and simultaneously operates the electronic three-way valve 80 to service the tank 60. It is provided with a working tank raw material detection sensor 100 for blocking the flow path to the (), and stops the operation of the pump 50 when the upper limit water level.

상기 펌프(50)의 흡입구측에는 상기 서비스탱크(60)와 서비스관로(112)로 연결되어 상기 작업탱크(70)내의 원료량이 하한 수준일 경우 서비스탱크(60)내의 원료를 펌프(50)의 흡입구측에 공급하기 위한 수동식 3방밸브(110)가 설치되어 있다.The suction port side of the pump 50 is connected to the service tank 60 and the service pipe 112 so that the raw material in the service tank 60 when the amount of raw material in the working tank 70 is the lower limit level, the suction port of the pump 50. Manual three-way valve 110 for supplying to the side is provided.

미설명 부호 55는 열교환기이다.Reference numeral 55 is a heat exchanger.

이와 같이 구성된 작동상태를 서비스탱크(60) 및 작업탱크(70)내의 원료수위의 정도 감지에 따라 나누어 설명한다.The operating state configured as described above will be described by dividing according to the degree of detection of the raw material level in the service tank 60 and the working tank 70.

(가) 서비스탱크(60)와 작업탱크(70)가 모두 비어있을 경우(A) When both service tank 60 and work tank 70 are empty

즉, 서비스탱크 원료감지센서(90)와 작업탱크 원료감지센서(100)에서 원료의 하한수준을 감지했을 경우이다. 이는 최초로 서비스탱크(60)와 작업탱크(70)에 원료를 충전할 경우이다.That is, when the service tank raw material detection sensor 90 and the working tank raw material detection sensor 100 detects the lower limit level of the raw material. This is the case when the raw material is filled in the service tank 60 and the working tank 70 for the first time.

이때 수동식 3방밸브(110)는 서비스관로(112)를 차단하게 조작되어 있고, 전자식 3방밸브(110)는 서비스탱크(60)측 관로를 차단한다.At this time, the manual three-way valve 110 is operated to block the service line 112, the electronic three-way valve 110 blocks the service tank 60 side pipe.

따라서 펌프(50)가 구동되면, 원료통(40)내의 원료가 펌핑되어 작업탱크(70)내로 공급된다. 작업탱크(70)내로 원료가 채워져 상한 수준에 도달하면 전자식 3방밸브(80)가 작업탱크(70)측 유로를 차단하고 서비스탱크(60)측 유로를 개방한다.Therefore, when the pump 50 is driven, the raw material in the raw material container 40 is pumped and supplied into the working tank 70. When the raw material is filled into the working tank 70 to reach the upper limit level, the electronic three-way valve 80 blocks the working tank 70 side flow path and opens the service tank 60 side flow path.

전자식 3방밸브(80)의 절환동작으로 펌프(50)에서 토출되는 원료가 서비스탱크(60)내로 채워진다. 서비스탱크(60)내의 원료 수위가 높아져 상한 수위에 도달되면 펌프(50)의 구동은 정지한다.The raw material discharged from the pump 50 is filled into the service tank 60 by the switching operation of the electronic three-way valve 80. When the raw material level in the service tank 60 is raised to reach the upper limit level, the driving of the pump 50 is stopped.

이렇게 하여 서비스탱크(60) 및 작업탱크(70)내의 연료가 모두 채워지면 수동식 3방밸브(110)를 조작시켜 서비스관로(112)가 펌프(50)와 연결된다.When the fuel in the service tank 60 and the working tank 70 is filled in this way, the service pipe 112 is connected to the pump 50 by operating the manual three-way valve 110.

(나) 서비스탱크(60)는 풀상태이고 작업탱크(70)만 비어있을 경우(B) If the service tank 60 is full and only the working tank 70 is empty

즉, 작업탱크(70)내의 원료가 하한 수위에 도달되면 전자식 3방밸브(80)가 절환되어 서비스탱크(60)측 유로가 차단되고, 펌프(50)가 구동된다.That is, when the raw material in the working tank 70 reaches the lower limit level, the electronic three-way valve 80 is switched to block the service tank 60 side flow path, and the pump 50 is driven.

따라서 서비스탱크(60)에 저장된 원료가 서비스관로(112)를 경유하여 펌프 (50)에 흡인되어 관로(52)를 거쳐 작업탱크(70)로 투입된다.Therefore, the raw material stored in the service tank 60 is sucked by the pump 50 via the service pipeline 112 and is introduced into the working tank 70 via the pipeline 52.

이렇게 하여 작업탱크(70)내의 원료 수위가 높아져 상한 수위에 도달되면, 펌프(50)는 작동을 멈춘다.In this way, when the raw material level in the working tank 70 becomes high and an upper level is reached, the pump 50 will stop operation | movement.

이후에는 작업탱크(70)내의 원료가 발포 작업시마다 발포성형기(200)를 통해 취출되어져 사용된다.Thereafter, the raw material in the working tank 70 is taken out and used through the foam molding machine 200 every time the foaming operation.

이와 같이 본 실시예에서는 서비스탱크(60)와 작업탱크(70)에 원료를 채워넣은 후 먼저, 작업탱크(70)내의 원료를 소진한 후 서비스탱크(60)내의 원료를 작업탱크(70)로 공급시켜 사용하게 된다.Thus, in the present embodiment, after filling the raw material in the service tank 60 and the working tank 70, the raw material in the working tank 70 is exhausted, and then the raw material in the service tank 60 to the working tank 70 It is supplied and used.

이와 같이 구성되고 작용하는 본 발명은 1개의 펌프(50)에 의해 원료통(40)으로부터 서비스탱크(60)로, 서비스탱크(60)에서 작업탱크(70)로의 원료공급이 가능토록 함으로써 종래의 2 펌프 사용에 비해 전기에너지의 절감효과가 있고, 효율적인 장비사용이 가능하다.The present invention constructed and acting as described above enables the supply of raw materials from the raw material container 40 to the service tank 60 and the service tank 60 to the working tank 70 by one pump 50. Compared with the use of 2 pumps, it saves electrical energy and enables efficient equipment use.

또, 설비의 사양이 단순화되어 투자비를 절감할 수 있고, 원재료 사용량이 적은 시스템일수록 유리하다.In addition, it is possible to reduce the investment cost by simplifying the specifications of the equipment, it is advantageous for a system that uses less raw materials.

상술한 바와 같이 본 발명에 의하면 원료통내의 원료를 펌핑하기 위한 펌프, 펌프의 토출구측 관로에 연결된 전자식 3방밸브, 전자식 3방밸브에 각각 서비스탱크와 작업탱크를 연결하고, 펌프와 서비스탱크와는 서비스관로로 연결하여, 1개의 펌프에 의해 서비스탱크와 작업탱크로의 원료투입이 가능하여 장비의 사용효율이 증대되고, 사양의 단순화로 투자비를 절감할 수 있고, 원재료 사용량이 적은 시스템에 유리한 이점을 갖는다.As described above, according to the present invention, a pump for pumping raw materials in a raw material container, an electronic three-way valve connected to an outlet port side of the pump, and an electronic three-way valve are connected to a service tank and a working tank, respectively, Is connected to the service pipe, and the feed tank can be fed into the service tank and the working tank by one pump, increasing the use efficiency of the equipment, reducing the investment cost by simplifying the specifications, and advantageous for the system using less raw materials.
