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.

A clamp member has a pair of integral jaws defining an aperture in which the upper end of a punch adaptor is clamped when the jaws are forced closed. The adaptor has a punch fastened to its lower end, for example by a tongue and groove connection; and a slitter blade is releasably attached to the clamp member adjacent the flexible jaws. The upper end of the punch adaptor is tubular and has therein axially extending slots forming radially compressible sectors which can be forced into gripping engagement with an operating shaft when the jaws on the clamp m...

1. In a plastic bag making machine having a reciprocable operating shaft for moving a punch and a slitter blade toward and away from a plastic bag, a holder device, comprising a punch adaptor, a clamp member disposed to be attached to said operating shaft for reciprocation thereby, and having thereon a pair of integral, flexible jaws defining therebetween an aperture for releasably retaining therein one end of said punch adaptor, means for securing one end of a punch to the opposite end of said adaptor to be supported thereby on said clamp member so that the opposite end of said punch projects beneath said clamp member, means on said clamp member for securing one end of a slitting blade releasably to said clamp member adjacent said jaws, and in such manner that the opposite end of said blade projects beneath said clamp member adjacent said opposite end of said punch, and adjustable means for releasably urging said flexible jaws of said clamp member toward one another from a release position to a clamping position, when said one end of said adaptor is positioned in said aperture, thereby releasably to secure said one end of said adaptor in said clamp member. 2. In a machine as defined in claim 1, wherein said one end of said adaptor has therein, an axial bore that is insertable coaxially over one end of said reciprocable operating shaft, when said one end of said adaptor is in said aperture and said jaws are in their release position, and said one end of said adaptor is radially compressible into gripping engagement with said one end of said operating shaft when said jaws are moved to their clamping position, whereby said jaws are operable releasably to secure said punch to said clamp member, and releasably to secure said clamp member to said operating shaft. 3. In a machine as defined in claim 2, wherein said one end of said adaptor is tubular in configuration and has in the annular wall thereof a plurality of equi-angularly spaced, longitudinally extending slots operatively dividing said wall into a plurality of radially compressible sectors. 4. In a machine as defined in claim 1, wherein said means for securing said one end of a punch to said opposite end of said adaptor, comprises a tongue and groove connection for releasably connecting together a pair of confronting surfaces on said one end of said punch and said opposite end of said adaptor, respectively, said connection comprising a tongue shaped projection formed on one of said pair of surfaces and slidably seated in a correspondingly shaped groove formed in the other of said pair of surfaces. 5. In a machine as defined in claim 4, means for releasably retaining said tongue shaped projection seated in said groove, comprising a locking element mounted on one of the interconnected ends of said punch and said adaptor, respectively, for limited movement between a locking position in which said element blocks opposite ends of said groove to prevent withdrawal of said tongue shaped projection therefrom, and a release position in which opposite ends of said groove are exposed to permit withdrawal of said projection from said groove. 6. In a machine as defined in claim 5, including means normally urging said locking element resiliently into said locking position. 7. In a machine as defined in claim 1, wherein said means for securing one end of a slitting blade to said clamp member comprises, a clamping surface formed on said clamp member adjacent said jaws and disposed to engage one side of said one end of said slitting blade, a clamping plate adjustably mounted on said member and having thereon a clamping surface disposed to overlie said clamping surface on said member in spaced, generally parallel relation thereto, and disposed to engage the opposite side of said one end of said slitting blade, and manually operable clamping means connecting said clamping plate to said clamp member and operable selectively to force said clamping surfaces one toward the other thereby releasably to clamp said one end of said slitting blade therebetween. 8. In a machine as defined in claim 7, wherein said clamping means comprises a screw having a head on one end thereof and having a reduced diameter shank extending from said head through registering openings in said clamp member, said one end of said slitting blade, and said clamping plate, respectively, and a clamping element mounted on the end of said shank remote from said head and rotatable relative to said screw into and out of an operative position in which it effects the clamping of said one end of said blade between said clamping surfaces. 9. In a machine as defined in claim 8, wherein said clamping element is a nut threaded onto said shank coaxially thereof. 10. In a machine as defined in claim 8, wherein said clamping element is mounted adjacent one end thereof on said shank for pivotal movement about an axis transverse to the axis of said shank between blade clamping and release positions, respectively, and said clamping element has thereon a cam lobe movable toward and away from said clamping surfaces upon pivotal movement of said clamping element in opposite directions. 11. A device for releasably mounting a punch and a slitting blade on an operating shaft for reciprocation thereby in unison, comprising a clamp member having thereon a pair of clamping jaws, a punch adaptor projecting at one end between said jaws, means on said clamp member for adjustably urging said jaws toward one another thereby firmly to grip said one end of said adaptor releasably between said jaws, means for connecting one end of a punch to the opposite end of said adaptor to be supported thereby beneath said clamp member, and means on said clamp member for releasably securing one end of a slitting blade to said clamp member adjacent said jaws so that the opposite end of said blade is supported beneath said clamp member adjacent said punch, said one end of said adaptor being generally tubular in configuration so that it can be inserted coaxially over one end of said operating shaft thereby to surround said one end of said shaft, and being radially compressible so that when said jaws are urged toward one another to grip said one end of said adaptor, said one end of the adaptor is compressed radially inwardly to grip and secure the entire clamp member to said shaft for reciprocation thereby. 12. A device as defined in claim 11, wherein said means for securing one end of said slitting blade to said clamp member comprises a pressure plate adjustably mounted on said clamp member to engage said one end of said blade at one side thereof and to urge the opposite side of said blade against a clamping surface on said clamp member, and means for releasably urging said pressure plate toward said clamping surface thereby to grip said one end of said blade releasably between said pressure plate and said clamping surface. 13. A device as defined in claim 12 wherein said means for urging said pressure plate toward said clamping surface comprises a camming member engaging the side of said pressure plate remote from said clamping surface, and pivotally mounted on said clamp member selectively to apply pressure to said pressure plate. 14. A device as defined in claim 11, wherein said means for connecting said one end of said punch to said adaptor comprises a tongue and groove connection between said punch and said adaptor, respectively, and spring-loaded means operative normally to prevent accidental disconnection of said tongue and groove connection.
