Abstract
A transfer device for transferring packaging units has at least one eccentric unit with a rotatably mounted eccentric element, which has a rod lead-through for a rod. The rod is mounted, by means of the rod lead-through, in a rotatable manner and in a displaceable manner in the axial direction of the eccentric element. The transfer device also has a first drive unit for rotating the eccentric element and a second drive unit for displacing the rod. A holding device for receiving packaging units is connected to the rod.
Claims15
A transfer device for transferring packaging units from a receiving region to a delivery region,
- wherein the transfer device comprises at least one eccentric unit which comprises:
- a rotatably mounted eccentric element having a rod lead-through, the rod-lead through being spaced apart from an axis of rotation of the eccentric element in a radial direction and extending parallel to an axis of rotation of the eccentric element;
- a rod, which extends through the eccentric element and which is mounted, by way of the rod lead-through, in a rotatable manner and in a displaceable manner in an axial direction of the eccentric element, wherein the rod lead-through has a radial-axial bearing, which is configured to mount the rod both axially as well as in a rotatory manner with respect to the eccentric element;
- a holding device, which is connected to the rod and which is configured to receive at least one packaging unit;
- a first drive unit, which is configured to rotate the eccentric element, thereby moving the holding device in a first plane, which is perpendicular to the axis of rotation of the eccentric element, between at least one retracted position and at least one operating position;
- and
- a second drive unit, which is configured to displace the rod between at least one first translation position and at least one second translation position in the axial direction of the eccentric element, thereby moving the holding device parallel to the axis of rotation of the eccentric element.
A method for transferring packaging units from a receiving region to a delivery region by means of a transfer device, wherein the transfer device comprises at least one eccentric unit which comprises:
- a rotatably mounted eccentric element, which has a rod lead-through, which is spaced apart from an axis of rotation of the eccentric element in a radial direction and which extends parallel to an axis of rotation of the eccentric element;
- a rod, which extends through the eccentric element and which is mounted, by means of the rod lead-through, in a rotatable manner and in a displaceable manner in an axial direction of the eccentric element, wherein the rod lead-through has a radial-axial bearing, which is configured to mount the rod both axially as well as in a rotatory manner with respect to the eccentric element;
- a holding device, which is connected to the rod and which is configured to receive at least one packaging unit;
- a first drive unit, which is configured to rotate the eccentric element, thereby moving the holding device in a first plane, which is perpendicular to the axis of rotation of the eccentric element, between at least one retracted position and at least one operating position;
- and
- a second drive unit, which is configured to displace the rod between at least one first translation position and at least one second translation position in the axial direction of the eccentric element, thereby moving the holding device parallel to the axis of rotation of the eccentric element;
- wherein the method comprises the steps of:
- rotating the eccentric element by means of the first drive unit in order to move the holding device into an operating position;
- receiving the at least one packaging unit in the receiving region by means of the holding device;
- rotating the eccentric element by means of the first drive unit in order to move the holding device into a retracted position;
- displacing the rod from a first translation position into a second translation position by means of the second drive unit;
- rotating the eccentric element by means of the first drive unit in order to move the holding device into an operating position;
- delivering the at least one packaging unit in the delivery region by way of the holding device;
- rotating the eccentric element by means of the first drive unit in order to move the holding device into a retracted position;
- and
- displacing the rod from the second translation position into a first translation position by means of the second drive unit.
