The engaging element (6) has a profile structure (33) supported by a carrier structure (34) and facing the base element (6) in the closed position of the tool (5), wherein springs (38) being arranged between the profile structure (33) and the carrier structure (34) such that the springs (38), when the tool (5) has been moved to its closed position, are compressed to a predetermined extent.
摘要:
A method for producing container blanks (2) from a material web (3) by joining opposite wall portions of the material web (3) along connecting portions (11) outlining said container blanks (2), comprising deflecting said material web (3) over a tool holder (4), rotating the tool holder (4) to move tools (5) supported by the same along a working path (WP), and by continued rotation of the tool holder (4), moving the tools (5) along a return path (RP) to the beginning of said working path (WP). Each tool, for providing said joining, is engaged with the material web (3) and moved together with said material web (3) during the movement of the tool (5) along said working path (WP), wherein the tool holder (4) is rotated at such a speed of rotation that each tool (5) maintains its engagement with said material web (3) during the movement of the tool (5) along said working path (WP) for a period of time in the range of 1-2 s.
摘要:
A system and a method for filling a package (2) of the collapsible type with a product in the form of a powder or liquid. The system comprises a package (2), which has a chamber defined by flexible walls, and an arrangement (1 ) for filling a package (2) of the collapsible type with a product in the form of a powder or liquid. Moreover, the arrangement comprises a filling tube (4) with an end portion (6) which is made of a stiff material and which has an outer circumference (C2), and which end portion (6), in order to transfer said product to the chamber, can be inserted into a filling channel (3) of the package (2), which filling channel (3) has an inner circumference (C1), and a clamping element (5) which is designed to grip the end portion (6) and the filling channel (3) when said end portion (6) is inserted into said filling channel (3), so as to create a seal between the end portion (6) and the filling channel (3). The system is characterized in that the difference between the inner circumference (C1 ) of the filling channel (3) and the outer circumference (C2) of the end portion (6) is less than or equal to four times a wall thickness of the package walls, such that the ability of the filling channel (3) to form folds when gripped by means of the clamping element (5) is eliminated.
摘要:
A device for handling containers (2) of a collapsible type, comprising one or more stations (S) and a transport unit (4). The device is arranged to receive said containers (2) oriented in a first direction (P1) and the transport unit (4) is arranged to transport said containers (2) to at least one of said stations (S) by moving the containers (2) in a second direction (P2) along a curved path (6), said second direction (P2) being perpendicular to said first direction (P1). The device has a holding means provided for said at least one station (S) and located in a stationary position adjacent to the station (S) and a transfer means (18), which is provided for said at least one station (S) and carried by the transport unit (4) and which is cyclically movable along an endless path between a pick-up position (A) and a delivery position (B) located adjacent to the station (S). The transfer means (18) is arranged to pick up at least one container (2) in the pick-up position (A) and transfer said at least one container (2), in the delivery position (B), to the holding means. The invention also concerns a method for handling containers of a collapsible type in a filling machine.
