Machine for sealed cover for a set of documents
The invention concerns a machine for providing a sealed cover for documents comprising a document conveying table ( 18 ) with a general longitudinal shape, arranged upstream of a unit for inserting ( 20 ) said documents in an envelope ( 26 ), at least a contact member ( 40, 42 ) mobile longitudinally, under the action of driving means ( 76, 82, 84, 88 ) in the direction of the inserting unit and which is designed to drive the documents on the conveying table, the driving means being distant from the inserting unit. The invention is characterized in that said at least one contact member is arranged on a mobile support ( 44 ) linked to the driving means in a zone ( 44 b ) located upstream of said at least one contact member, the driving means imposing on said at least one contact member is reciprocating translational movement between two extreme positions, in one of said extreme positions said at least one contact member being placed proximate to the inserting unit.
1. A machine for inserting documents into an envelope,
the machine including a generally elongate document routing table on the upstream side of an insertion unit for inserting said documents into an envelope, and
at least one contact member that is adapted to be moved longitudinally by drive means remote from the insertion unit toward the insertion unit and is adapted to push the documents on the routing table,
wherein said at least one contact member is on a mobile support connected to the drive means in an area upstream of said at least one contact member and the drive means imposing on said at least one contact member and on the mobile support a reciprocating movement in translation between two positions in one of which said at least one contact member is in the vicinity of the insertion unit,
wherein the drive means include an endless loop longitudinal transport member rotatably mounted around two parallel shafts perpendicular to the longitudinal direction of the table and contained in a plane under and parallel to the routing table and the support is connected to said drive means by a connecting mechanism means for reducing the mechanical forces exerted on the transport member by distributing those forces in the mechanism,
wherein the connecting mechanism means includes at least one pusher member perpendicular to the longitudinal direction of movement of the support for pushing the support and link means articulated about two link shafts that are parallel to the shafts of the transport member and one of which is fastened to the pusher member and disposed in the plane and the other of which is fastened to the transport member, wherein the connecting mechanism means includes means for holding the pusher member in a position perpendicular to the longitudinal direction of movement of the support,
wherein the holding means include two bearings mounted on the pusher member, offset relative to each other in the longitudinal direction and respectively cooperating with two parallel longitudinal grooves disposed one above the other.
2. The machine according to claim 1 , wherein the connecting mechanism means converts rotation of the longitudinal transport member into longitudinal reciprocation in translation.
3. The machine according to claim 1 , wherein the pusher member has a reduced section area in an upper portion in which the maximum forces are exerted.
4. The machine according to claim 1 , wherein the link means comprise a mechanical fuse.
5. The machine according to claim 1 , further comprising guide means for guiding longitudinal movement in translation of the support.
6. The machine according to claim 5 , wherein the guide means include bearings cooperating with longitudinal guide members.
7. The machine according to claim 6 , wherein the longitudinal guide members are angle-irons.
8. A machine for inserting documents into an envelope, the machine including a generally elongate document routing table on the upstream side of an insertion unit for inserting said documents into an envelope, and
at least one contact member that longitudinally by a drive mechanism remote from the insertion unit toward the insertion unit and is adapted to push the documents on the routing table,
wherein the at least one contact member is on a mobile support connected to the drive mechanism in an area upstream of said at least one contact member and the drive mechanism imposing on said at least one contact member and on the mobile support a reciprocating movement in translation between two end positions of the reciprocating movement in one of which said at least one contact member is in the vicinity of the insertion unit, wherein,
the drive mechanism includes an endless loop longitudinal transport member rotatably mounted around two parallel shafts perpendicular to the longitudinal direction of the table and contained in a plane under and parallel to the routing table; and
the support is connected to said drive mechanism by a connecting mechanism, wherein,
the connecting mechanism includes at least one pusher member perpendicular to the longitudinal direction of movement of the support for pushing the support; and
the connecting mechanism includes at least one link articulated about two link shafts that are parallel to the shafts of the transport member and one of which is fastened to the pusher member and disposed in the plane and the other of which is fastened to the transport member, wherein,
the connecting mechanism includes a holder for holding the pusher member in a position perpendicular to the longitudinal direction of movement of the support, and wherein,
the holder includes two bearings mounted on the pusher member, offset relative to each other in the longitudinal direction and respectively cooperating with two parallel longitudinal grooves disposed one above the other.
