Abstract
The invention relates to improvements in the technical field of supplying cannulas (2). For this purpose, there is proposed, inter alia, a supply device (1), the removal carriage (4) of which includes at least one cannula receptacle (6) for accommodating a cannula (2), said cannula receptacle (6) being connectable or connected to a vacuum source (7) in order for a cannula (2) to be fixed in the cannula receptacle (6).
Claims21
A supply device (1) for supplying cannulas (2), comprising:
- a cannula magazine (3);
- a removal carriage (4) configured for removing cannulas (2) from the cannula magazine (3) and for transporting the cannulas (2) to a supply position, the removal carriage (4) including at least one cannula receptacle (6) for a cannula (2);
- said cannula receptacle (6) being connectable or connected to a vacuum source (7) that is apply able to fix one said cannula (2) in the cannula receptacle (6);
- a lifting means (17) for raising and lowering a stock of cannulas located in the cannula magazine (3);
- and
- the removal carriage (4) has a longitudinal groove (22) into which the lifting means (17) is engageable.
A method for supplying cannulas for a downstream process step in processing of cannulas, the method comprising:
- providing a supply device for the cannulas, the supply device including a cannula magazine, a removal carriage configured for removing the cannulas from the cannula magazine and for transporting the cannulas to a supply position, the removal carriage including at least one cannula receptacle for one said cannula, said cannula receptacle being connectable or connected to a vacuum source that is apply able to fix one said cannula in the cannula receptacle, a lifting means for raising and lowering a stock of cannulas located in the cannula magazine, wherein the removal carriage has a longitudinal groove into which the lifting means is engageable, and a position correction device configured to align one said cannula, arranged in the at least one cannula receptacle, in a target position;
- using the supply device and removing the cannulas by the removal carriage from the cannula magazine of the supply device;
- detecting a position of at least of one said cannula in the at least one cannula receptacle of the removal carriage using at least one sensor;
- bringing the cannula to a target position;
- and
- using a sensor connected to a controller of the supply device to detect a positional deviation of the cannula from the target position and
- using a position correction device of the supply device to correct the positional deviation of the cannula from the target position to bring the cannula into the target position.
A computer program fixed in a tangible medium, comprising commands that cause a supply device for cannulas to carry out a method for supplying cannulas, wherein the supply device includes a cannula magazine, a removal carriage configured for removing the cannulas from the cannula magazine and for transporting the cannulas to a supply position, the removal carriage including at least one cannula receptacle for one said cannula, said cannula receptacle being connectable or connected to a vacuum source that is apply able to fix one said cannula in the cannula receptacle, a lifting means for raising and lowering a stock of cannulas located in the cannula magazine, wherein the removal carriage has a longitudinal groove into which the lifting means is engageable, and a position correction device configured to align one said cannula, arranged in the at least one cannula receptacle, in a target position;
- and the method comprises:
- using the supply device and removing the cannulas by the removal carriage from the cannula magazine of the supply device;
- detecting a position of at least of one said cannula in the at least one cannula receptacle of the removal carriage using at least one sensor;
- bringing the cannula to a target position;
- and
- using a sensor connected to a controller of the supply device to detect a positional deviation of the cannula from the target position and
- using a position correction device of the supply device to correct the positional deviation of the cannula from the target position to bring the cannula into the target position.
