Abstract

A printing system to hold printing material comprises a sealing interface to seal a container with respect to a printing chamber volume of the printing system, the container to hold the printing material. The printing system comprises a lifting system to move the container between a first position in which the container is to be lifted and a second position at which the container is lifted and contacts the seal so as to seal the container. The lifting system is to non-hyperstatically constrain the container.

First claim

What is claimed is:

1. A printing system to hold printing material, the printing system comprising:
a sealing interface to seal a container with respect to a printing chamber volume of the printing system, the container to hold the printing material; and
a lifting system to move a container between a first position in which the container is to be lifted and a second position at which the container is lifted and contacts the seal so as to seal the container, wherein the lifting system is to non-hyperstatically constrain the container.

2. The printing system of claim 1 , wherein the lifting system is to support the container at exactly three constraining engaging regions of the container to non-hyperstatically constrain the container when moving the container.

3. The printing system of claim 2 , wherein the lifting system is to vertically move the container, wherein the three constraining engaging regions form contact regions to be engaged by the lifting system.

4. The printing system of claim 1 , wherein the lifting system comprises a first motor to move a first cam to provide for engagement of the container at a first engaging region and comprises a second motor to move a second cam to provide for engagement of the container at a second engaging region.

5. The printing system of claim 4 , comprising an encoder to encode a movement of the first motor to obtain a movement signal, wherein the printing system is to control the second motor based on the movement signal to obtain a synchronized movement of the first motor and the second motor.

6. The printing system of claim 1 , wherein the lifting system comprises a cam follower to guide a movement of the container by engaging the container at a third engaging region.

7. The printing system of claim 1 , wherein the lifting system is to move the container along a lifting direction and to constrain an in-plane movement perpendicular to the lifting direction, and to constrain a tilt and a position of the container.

8. The printing system of claim 1 , wherein a first engaging means to engage the container at a first engaging region and a second engaging means to engage the container at a second engaging region are to vertically carry the container, wherein a third engaging means is to engage the container at a moving third engaging region, a movement of the third engaging region following a movement of the first and/or second engaging means.

9. The printing system of claim 1 , wherein the lifting system leaves a degree of freedom for a movement of the container at a first engaging region along a first lateral direction perpendicular to a lifting direction generated by the lifting system, constrains, at a second engaging region, a movement along the first lateral direction and a second lateral direction perpendicular to the lifting direction and the first lateral direction and constrains, at a third engaging region, a movement along the second lateral direction whilst allowing for a movement along the first lateral direction.

10. The printing system of claim 1 , wherein a movement of the container generated by the lifting system is to seal a sealing of the printing system between the container and an environment thereof.

11. The printing system of claim 1 , wherein the lifting system comprises a cam arranged rotably around an axis of rotation and a motor to rotate the cam around the axis of rotation to thereby move the container, and wherein a lateral surface of the cam comprises a first surface area along which a rotation of the cam provides for a movement of the container and comprises a second surface area along which the rotation of the cam provides for a maintained position of the container.

12. The printing system of claim 11 , wherein a shape of the first surface area is non-uniformly eccentric with respect to the axis of rotation of the cam and wherein the second surface area is radially shaped with respect to the axis of rotation.

13. The printing system of claim 11 , wherein the second surface area is associated with an end position of the container such that the cam engages with a mechanical element or the container with the second surface area at the end position of the container.

14. A printing system to hold printing material, the printing system comprising:
a sealing interface to seal a container with respect to a printing chamber volume of the printing system, the container to hold the printing material; and
a lifting system to move a container between a first position in which the container is to be lifted and a second position at which the container is lifted and contacts the seal so as to seal the container;
wherein the lifting system comprises a first motor to move the container at a first engaging region and comprises a second motor to move the container at a second engaging region; and
wherein the lifting system comprises a controller to control the first motor and comprises an encoder to encode a movement of the first motor to obtain a movement signal and to control the second motor based on the movement signal.

15. A printing system to hold printing material, the printing system comprising:
a sealing interface to seal a container with respect to a printing chamber volume of the printing system, the container to hold the printing material;
a lifting system to move a container between a first position in which the container is to be lifted and a second position at which the container is lifted and contacts the seal so as seal the container;
wherein the lifting system comprises a cam to convert a movement of an actuator into a movement of the container, the cam arranged rotably around an axis of rotation; and
wherein a lateral surface of the cam is to provide for the movement of the container, wherein during a rotation of the cam a first surface area of the lateral surface provides for a displacement of the container and a second surface area of the lateral surface provides for a maintained position of the container.
