Abstract
An object former surrounds a chamber and forms an object in the chamber. A web moving member moves a web of wrapping material towards a wrapping material inlet guiding into the chamber. The web is injected into the chamber. The object in the chamber is wrapped. A moveable severing member of a severing device severs the web. A movement of the web moving member is coupled with a movement of the moveable severing member from a parking position into an intermediate position. A severing actuator moves the moveable severing member from the intermediate position into a web severing position. thereby severing the web.
Claims20
A wrapping apparatus for wrapping an object contained in a chamber, comprising:
- a wrapping material inlet leading into the chamber, the wrapping apparatus comprising:
- a web moving member positioned outside of the chamber;
- a web moving actuator;
- and
- a severing device comprising a moveable severing member being moveable between a parking position and a web severing position;
- and
- a mechanical coupling element for coupling the web moving member with the moveable severing member,
- wherein the web moving member is moveable with respect to the wrapping material inlet between at least one remote position and an adjacent position and arranged for moving a web of wrapping material towards the wrapping material inlet while being moved into the adjacent position,
- wherein the web moving actuator is arranged for moving the web moving member with respect to the wrapping material inlet between both positions,
- wherein the wrapping apparatus is arranged to inject the moved web of wrapping material through the wrapping material inlet into the chamber,
- wherein the severing device with the moveable severing member being moved into the web severing position is arranged to sever the web at a severing location positioned outside of the chamber after the web is injected into the chamber,
- wherein the severing device further comprises a severing actuator operable independently from the web moving actuator,
- wherein the moveable severing member is further moveable into an intermediate position,
- wherein the moveable severing member being in the intermediate position is spaced apart from the web and has a smaller distance to the web compared with the moveable severing member being in the parking position and a larger distance compared with the moveable severing member being in the web severing position,
- wherein the mechanical coupling element couples a movement of the web moving member from a first position into a second position with a movement of the moveable severing member from the parking position into the intermediate position
- wherein the wrapping apparatus is arranged to temporarily keep the web moving member in the second position, thereby causing the mechanical coupling element to simultaneously keep the moveable severing member in the intermediate position, and
- wherein the severing actuator is arranged to move the moveable severing member from the intermediate position into the web severing position and from the web severing position back into the intermediate position.
14 more elements
The wrapping apparatus according to claims claim1, wherein the wrapping apparatus comprises a position sensor arranged to detect the event that the web moving member or that the moveable severing member has reached a given position with respect to the wrapping material inlet, and
- wherein the wrapping apparatus is arranged to trigger the severing actuator for moving the moveable severing member into the web severing position depending on signals from the position sensor.
The wrapping apparatus according to claims claim1, wherein the severing device comprises an energy storing device,
- wherein a movement of the moveable severing member from the web severing position into the intermediate position increases the kinetic energy stored in the energy storing device, and
- wherein the severing actuator is arranged to move the moveable severing member from the intermediate position into the web severing position by using kinetic energy taken from the energy storing device.
A method for wrapping an object while the object is contained in a chamber,
- wherein a wrapping material inlet guides into the chamber,
- wherein the method is performed by using a wrapping apparatus comprising:
- a web moving member being moveable with respect to the wrapping material inlet between at least one remote position and an adjacent position;
- a web moving actuator;
- a severing device with a moveable severing member being moveable between a parking position and a web severing position;
- and
- a mechanical coupling element,
- wherein the method comprises the steps of:
- the web moving actuator moving the web moving member from the or one remote position into the adjacent position;
- the moved web moving member moving a web of wrapping material towards the wrapping material inlet which leads into the chamber;
- injecting the moved web through the wrapping material inlet into the chamber;
- moving the moveable severing member into the web severing position after the web is injected into the chamber;
- the movement of the moveable severing member causing the moved moveable severing member to sever the web at a severing location outside of the chamber;
- and
- the web moving actuator moving the web moving member from the adjacent position into the or one remote position,
- wherein the mechanical coupling element transfers a movement of the web moving member from a first position into a second position onto the moveable severing member,
- wherein the severing device further comprises a severing actuator (25) which can be operated independently from the web moving actuator and the moveable severing member is further moveable into an intermediate position,
- wherein the step that the movement of the web moving member is transferred onto the moveable severing member comprises the further step that the movement of the web moving member from the first position into the second position causes the mechanical coupling element to move the moveable severing member from the parking position into the intermediate position, thereby decreasing the distance between the moveable serving member and the web,
- wherein the moveable severing member being moved into the inteimediate position remains in a distance to the web,
- wherein the method comprises the further steps of
- temporarily keeping the web moving member in the second position;
- and
- the mechanical coupling element simultaneously keeping the moveable severing member in the intermediate position,
- wherein the step that the web is severed comprises the step of the severing actuator moving the moveable severing member from the intermediate position into the web severing position, and
- wherein the method comprises the further step of the severing actuator moving the moveable severing member from the web severing back into the intermediate position.
