연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

1. A fluid dispensing system, comprising: a first supply source for supplying a first fluid to be dispensed;a second supply source for supplying a second fluid to be dispensed wherein the second fluid is different front the first fluid;an adhesive manifold;an applicator assembly positioned downstream from, mounted directly to, and disposed in fluid communication with the adhesive manifold and having at least one nozzle member;first and second pumps removably mounted directly on the adhesive manifold, such that the adhesive manifold is disposed downstream from the first and second pumps and upstream from the applicator assembly, the first and second pumps for pumping the respective first and second fluids from said respective first and second supply sources to said at least one nozzle member through the adhesive manifold;first and second output supply passageways connecting in the applicator assembly to form a third output supply passageway downstream from, and in fluid communication with, the first and second output supply passageways, to fluidically interconnect said first and second pumps to said at least one nozzle member so as to supply the first and second fluids to said at least one nozzle member;first and second plug members internally disposed completely within respective first and second output supply passageways at an edge of the applicator assembly where the adhesive manifold abuts the applicator assembly, each plug member movable to an INSTALLED state positioned completely in a respective output supply passageway or a REMOVED state removed from a respective output supply passageway; andthe nozzle member is connected to the third output supply passageway through a valve assembly located in the applicator assembly downstream from said first and second plug members and the first and second output supply passageways, and upstream from said at least one nozzle member, said valve assembly includes a valve for permitting said fluid dispensing system to achieve THREE dispensing states, a FIRST state wherein said valve is OPENED, said first plug member is REMOVED from said first output supply passageway to permit the first fluid to be dispensed from said first pump and out from said at least one nozzle member, and said second plug member is INSTALLED in said second output supply passageway, a SECOND state wherein said valve is OPENED, said first plug member is INSTALLED in said first output supply passageway, and said second plug member is REMOVED from said second output supply passageway to permit the second fluid to be dispensed from said second pump and out from said at least one nozzle member, and a THIRD state wherein said valve is OPENED and said first and second plug members are REMOVED from said first and second output supply passageways, respectively, to permit both of the first and second fluids to be dispensed from said first and second pumps and out from said at least one nozzle member. 2. The fluid metering system as set forth in claim 1, wherein: said first and second pumps of said at least two pumps are disposed within a single pump assembly. 3. The fluid metering system as set forth in claim 1, wherein: said first and second pumps are disposed within separate first and second pump assemblies. 4. The fluid metering system as set forth in claim 1, wherein: said valve comprises an electrically controlled, solenoid-actuated control valve. 5. The fluid metering system as set forth in claim 1, wherein: said first and second pumps comprise rotary gear metering pumps for outputting metered amounts of the first fluid and/or the second fluid to be dispensed. 6. The fluid metering system as set forth in claim 3, wherein: each of said first and second pump assemblies comprises four pumps disposed in a side-by-side array. 7. The fluid metering system as set forth in claim 6, wherein: said at least one nozzle member comprises four nozzle members disposed in a side-by-side array and respectively fluidically connected to said four pumps of each one of said separate first and second sets of pumps so as to dispense the first fluid and/or the second fluid onto a substrate in longitudinally extending strips as the substrate passes said four dispensing nozzle members. 8. The fluid metering system as set forth in claim 7, wherein: said longitudinally extending strips of said first fluid and/or said second fluid, dispensed onto the substrate can comprise either one of the first and second fluids depending upon which one of said pumps are permitted to output its fluid to its respective nozzle member such that different patterns of the first and/or second fluids can be deposited upon the substrate and at different locations thereof. 9. The fluid metering system as set forth in claim 3, wherein: said first and second pump assemblies are fixedly, but removably mounted upon the adhesive manifold. 10. A fluid dispensing system comprising: a first supply source for supplying a first fluid to be dispensed;a second supply source for supplying a second fluid to be dispensed wherein the second fluid is different from the first fluid;an adhesive manifold;a first gear pump assembly removably mounted directly on the adhesive manifold, the first gear pump assembly configured to pinup a first fluid to the adhesive manifold;a second gear pump assembly removably mounted directly on the adhesive manifold, the second gear pump assembly configured to pump a second fluid to the adhesive manifold;an applicator assembly mounted directly on, in abutting relationship with, and downstream from, the adhesive manifold, such that the adhesive manifold is disposed between the applicator assembly and the first gear pump assembly and the second gear pump assembly;a nozzle member disposed on the applicator assembly;a first output supply passageway fluidically connected to and configured to receive the first fluid from the first gear pump assembly, the first output supply passageway extending through the adhesive manifold and into the applicator assembly;a second output supply passageway fluidically connected to and configured to receive second fluid from the second gear pump assembly, the second output supply passageway extending through the adhesive manifold and into the applicator assembly;a third output supply passageway fluidically connected to the first and second output supply passageways in the applicator assembly and configured to receive one of the first fluid from the first output supply passageway or the second fluid from the second output supply passage, or both of the first fluid and the second fluid from the first output supply passageway and second output supply passageway, respectively, the third output supply passageway extending in the applicator assembly and fluidically connecting the first and second output supply passageways with the nozzle member;a first plug member removably disposed in the first output supply passageway at an edge of the applicator assembly where the adhesive manifold abuts the applicator assembly, movable to an INSTALLED position preventing the first fluid from flowing to the third output supply passageway or a REMOVED position allowing the first fluid to flow to the third output supply passageway;a second plug member removably disposed in the second output supply passageway at an edge the applicator assembly where the adhesive manifold abuts the applicator assembly, movable to an INSTALLED position preventing the second fluid from flowing to the third output supply passageway or a REMOVED position allowing the second fluid to flow to the third output supply passageway; andthe nozzle member is connected to the third output supply passageway by a valve assembly located in the applicator assembly downstream from the first output supply passageway and second output supply passageway and upstream flour the nozzle member, the valve actuatable between an OPENED position and a CLOSED position to selectively permit or prevent the first fluid and/or the second fluid to flow to the nozzle member for discharge.
