Abstract
The transfer device has a means of securing the grip of the lifting device on the lid (14), in the form of an elastic suction pad (11) with narrowing and widening aperture and a suction line (21). The closer (8) can grip the lid and exert suction on it. There is a monitoring device, possibly with a sensor, to monitor the seating of the lid on the lifting device.
Claims33
An apparatus for transferring flowable material, comprising:
- at least one opening for discharging said material;
- closure means for discharging material from said opening, said closure means being displaceable from an open position to a closed position;
- actuator means for displacing said closure means from said open position into said closed position along an axis of actuation;
- at least one docking surface for engaging a counter-surface of a take over device which defines a charging opening of said take over device, said take over device being normally closed by a cover means;
- a source of vacuum;
- and
- at least one vacuum operated lid removal surface for engaging said cover means and freeing said charging opening of said take over device, said lid removal surface being connected to said vacuum source and being immediately formed as said closure means to provide engagement of said lid removal surface and said cover means.

An apparatus for transferring flowable material, comprising:
- at least one opening for discharging said material;
- closure means for said opening having a first, inner conical surface displaceable from an open position to a closed position;
- actuator means for displacing said closure means from said open position into said closed position along an axis of actuation;
- at least one docking surface for engaging a counter-surface of a take over device which defines a charging opening of said take over device, said take over device being normally closed by a cover means which comprise a second, outer conical surface;
- a source of vacuum;
- and
- at least one vacuum operated lid removal surface for engaging said cover means and freeing said charging opening of said take over device, said lid removal surface being connected to said vacuum source and being immediately formed on an inner surface of said closure means to provide engagement of said lid removal surface and said cover means.

An apparatus for transferring bulk material, comprising:
- at least one opening for discharging said material, closure means for said opening displaceable from an open position to a closed position;
- actuator means for displacing said closure means from said open position into said closed position along an axis of actuation;
- at least one docking surface for engaging a counter-surface of a take over device which defines a charging opening of said take over device, said take over device being normally closed by a cover means;
- a source of vacuum;
- at least one vacuum operated lid removal surface for engaging said cover means and freeing said charging opening of said take over device;
- suction conduit means of a certain gas conductivity interconnected between said lid removal surface and said vacuum source to connect said lid removal surface to said vacuum source;
- monitoring means for monitoring engagement of said lid removal surface and said cover means, said monitoring means emitting an engagement signal;
- and
- evaluating means receiving said engagement signal for ensuring engagement of said lid removal surface and said cover means.
