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 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.

Methods for storing and moving adhesive particulate to an adhesive melter are disclosed. An interior space of a supply hopper is filled with adhesive particulate. A transfer pump is actuated to generate a vacuum at an inlet of the transfer pump to actuate removal of the adhesive particulate from the supply hopper. A consistent minimized depth of the adhesive particulate located directly above the inlet is maintained with a shroud located within the interior space of the supply hopper. In addition, adhesive particulate can be received in an interior space of a container. An open space is maintained within the interior space of the container proximate the pump inlet, where the open space entrains gas to be drawn by the transfer pump. The transfer pump can be actuated to generate a vacuum at the pump inlet to cause removal of the adhesive particulate from the container.

1. A method of storing and moving adhesive particulate to an adhesive melter, the method comprising: filling an interior space of a supply hopper with adhesive particulate;actuating a transfer pump to generate a vacuum at an inlet of the transfer pump to actuate removal of the adhesive particulate from the supply hopper; andmaintaining a consistent depth of the adhesive particulate located directly above the inlet with a shroud located within the interior space of the supply hopper and an open space at least partially defined by the shroud, the shroud being spaced from and surrounding at least a portion of the inlet of the transfer pump, and the consistent depth being less than a variable total depth of adhesive particulate within the supply hopper. 2. The method of claim 1, further comprising: entraining an amount of a make-up gas within the open space such that the open space is proximate to the inlet of the transfer pump to thereby increase an amount of make-up gas located around the adhesive particulate proximate to the inlet. 3. The method of claim 1, further comprising: deflecting adhesive particulate from around a housing of the transfer pump with the shroud. 4. The method of claim 1, further comprising: vibrating the shroud in order to vibrate the adhesive particulate proximate to the inlet of the transfer pump. 5. The method of claim 1, further comprising: exhausting a gas supply proximate to the inlet of the transfer pump to increase an additional amount of a make-up gas located around the adhesive particulate proximate to the inlet. 6. The method of claim 5, wherein a vibrator is operably connected to the gas supply, and the method further comprises: operating the vibrator with gas from the gas supply; androuting the gas from the vibrator to exhaust proximate to the inlet of the transfer pump. 7. A method of storing and moving adhesive particulate to an adhesive melter using a transfer pump with a pump inlet communicating with a container, the method comprising: receiving adhesive particulate in an interior space of the container;maintaining an open space within the interior space of the container proximate the pump inlet, the open space entraining gas from an exhaust gas conduit to be drawn by the transfer pump, and the open space not being filled with the adhesive particulate; andactuating the transfer pump to generate a vacuum at the pump inlet to cause removal of the adhesive particulate from the container for delivery to the adhesive melter. 8. The method of claim 7, wherein maintaining the open space further comprises: controlling a flow of the adhesive particulate within the interior space to prevent the adhesive particulate from filling the open space. 9. The method of claim 7, further comprising: agitating the adhesive particulate in the interior space proximate to the pump inlet to reduce compaction and thereby fluidize the adhesive particulate proximate the pump inlet. 10. The method of claim 9, wherein agitating the adhesive particulate further comprises: vibrating the adhesive particulate with a vibrator operatively coupled to the container. 11. The method of claim 10, wherein the vibrator is air-driven, and the method further comprises: exhausting a gas supply used to operate the vibrator into the open space for increasing an additional amount of make-up gas located around the adhesive particulate proximate to the pump inlet. 12. The method of claim 7, wherein maintaining the open space within the interior space of the container proximate the pump inlet comprises maintaining the open space within the interior space of the container proximate the pump inlet with a shroud located within the interior space of the container. 13. The method of claim 12, further comprising: deflecting adhesive particulate from around the pump inlet with the shroud. 14. A method of storing and moving adhesive particulate to an adhesive melter, the method comprising: filling an interior space of a supply hopper with adhesive particulate;actuating a transfer pump to generate a vacuum at an inlet of the transfer pump to actuate removal of the adhesive particulate from the supply hopper;maintaining a consistent depth of the adhesive particulate located directly above the inlet with a shroud located within the interior space of the supply hopper and an open space at least partially defined by the shroud, the consistent depth being less than a variable total depth of adhesive particulate within the supply hopper;exhausting a gas supply proximate to the inlet of the transfer pump to increase an additional amount of a make-up gas located around the adhesive particulate proximate to the inlet;operating a vibrator connected to the gas supply with gas from the gas supply; androuting the gas from the vibrator to exhaust proximate to the inlet of the transfer pump. 15. A method of storing and moving adhesive particulate to an adhesive melter using a transfer pump with a pump inlet communicating with a container, the method comprising: receiving adhesive particulate in an interior space of the container;maintaining an open space within the interior space of the container proximate the pump inlet, the open space entraining gas to be drawn by the transfer pump, and the open space not being filled with the adhesive particulate;actuating the transfer pump to generate a vacuum at the pump inlet to cause removal of the adhesive particulate from the container for delivery to the adhesive melter;agitating the adhesive particulate in the interior space proximate to the pump inlet to reduce compaction and thereby fluidize the adhesive particulate proximate the pump inlet;vibrating the adhesive particulate with an air-driven vibrator operatively coupled to the container; andexhausting a gas supply used to operate the vibrator into the open space for increasing an additional amount of make-up gas located around the adhesive particulate proximate to the pump inlet.
