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.

This is a high-speed, multi-lane machine and method for the continuous forming, filling and sealing of plastic or film pouches of various sizes commonly used to hold fluids, liquids, and viscous materials or other substances. The machine includes a film roll station, a pump station, a side seal station, a pull wheel station, a cross seal station, and a cross cut station. The invention provides for continuous production of pluralities of pouches without stops or delays by utilizing one or more moveable reciprocating carriages that travel with the flow of film through the machine, the carriages supporting each of the side sealing, cross sealing, and cross cutting stations. Coordination of the various stations is accomplished through electronic computer control, working in conjunction with a plurality of motion imparting devices such as servo motors, cam systems, linkages and the like. The various components of the machine are adjustable so that pouches of various lengths and/or widths may be formed using the same machine.

The machine of claim 1 wherein the reciprocating movement of each of said first, second and third stations is independent from the reciprocating movement of each of the other of said stations.3. The machine of claim 1 wherein said gripping apparatus comprises a pair of moveable parallel shafts, each shaft supporting a plurality of rollers at spaced intervals defining a plurality of pairs of opposing rollers positioned in alignment with said longitudinal heat sealing members of said first station.4. The machine of claim 1 wherein a plurality of dispensing tubes are provided in operative communication with said dispensers, each of said tubes extending between said sheets of film and through the spaced intervals between the plurality of pairs of rollers.5. The machine of claim 4 wherein a reservoir of product is provided, and said dispensers include a plurality of pumps for removing measured quantities of product from said reservoir and transferring said quantities through said dispensing tubes into said pouches as they are being formed.6. The machine of claim 1 wherein said transverse seals are perpendicular to said longitudinal seals.7. The machine of claim 1 wherein said plurality of blades are provided downstream from said longitudinal heat sealing members.8. The machine of claim 1 wherein said film support structure is provided on a side of said machine, and a plurality of guides are provided adjacent to said support structure to align and bring the sheets of film from each roll into close parallel proximity with each other prior to entering the machine.9. An apparatus continuosly for manufacturing and filling webbed pouches comprising:a. a support means for holding a pair of rolls of webbed film material; b. a pulling means for gripping and unrolling sheets of webbed film from each of said rolls; c. a plurality of dispensing means for inserting product into the pouches as they are being formed; d. a first sealing means that reciprocates along the path of said film through said apparatus for imparting a plurality of longitudinal seals upon said sheets of film to bond said sheets together along each of said seals without interrupting the movement of film through the apparatus; e. a plurality of cutting means disposed along said path for separating said sealed film sheets into longitudinal tubular strips; f. a second sealing means that reciprocates along the path of said film through said apparatus for imparting transverse seals at spaced intervals upon said pair of sheets of film to bond said sheets together along each of said seals without interrupting the movement of film through the apparatus; and g. a transverse cutting means that reciprocates along the path of said film through said apparatus for cutting across the centers of said transverse seals without interrupting the movement of film through the apparatus. 10. The apparatus of claim 9 wherein the reciprocating movement of each of said first sealing means, said second sealing means and said transverse cutting means is independent from the reciprocating movement of each of the other of said means.11.
