Abstract
A device and a method for testing tablets are disclosed. The device for testing tablets includes a test chamber, which has a crusher jaw and, lying opposite the latter, a counter-jaw. The device has a movable sheet metal strip, which is designed to position a tablet for testing. The longitudinal axis of the movable sheet metal strip is at an angle of less than 90° to the longitudinal axis of the direction of movement of the crusher jaw, and the direction of movement of the sheet metal strip corresponds to the longitudinal axis of the sheet metal strip.
Claims16
A device for testing tablets, comprising
- a test chamber having a crusher jaw and a counter jaw opposite the crusher jaw;
- a driver comprising a round base body and a plurality of driver arms extending radially from the round base body, wherein a distance between the driver arms at a transition of the driver arms to the base body corresponds substantially to a width of the crusher jaw,
- wherein in a testing position of the driver for testing a tablet in the test chamber two adjacent ones of the driver arms form lateral boundaries of the test chamber,
- wherein via rotation of the driver a first one of the driver arms pushes a tablet to be tested into the test chamber, and a second one of the driver arms adjacent the first driver arm pushes tablet material out of the test chamber after testing of the tablet;
- and
- a movable sheet metal strip, adapted to position the tablet for testing, wherein an angle between a longitudinal axis of the movable sheet metal strip and a longitudinal axis of a direction of movement of the crusher jaw is less than 90°, and a direction of movement of the sheet-metal strip corresponds to the longitudinal axis of the sheet-metal strip,
- said device being adapted so that the driver rotates in a first direction of rotation from the tablet to the test chamber until a side of the driver facing in the direction of rotation ends flush with a side of the test chamber facing in the direction of rotation so that at least a portion of the tablet is located outside the test chamber, and after rotation in the first direction of rotation the driver rotates in a second direction of rotation opposite the first direction of rotation until the tablet is located completely within the test chamber again.
A method for testing tablets, comprising:
- rotating a driver having driver arms so that one of the driver arms moves a tablet into a test chamber and another one of the driver arms adjacent the one of the driver arms moves tablet material present in the test chamber out of the test chamber,
- wherein the driver is rotated in a direction of rotation from the tablet toward the test chamber until a side of the one of the driver arms facing in the direction of rotation ends flush with a side of the test chamber facing in the direction of rotation so that at least a portion of the tablet is located outside the test chamber,
- wherein subsequent to rotating the driver in the first direction of rotation the driver is rotated in a second direction of rotation opposite the first direction of rotation until the tablet is located completely within the test chamber again;
- placing the tablet on a movable sheet metal strip for testing;
- orienting the tablet along at least one positioning surface by movement of the sheet metal strip;
- and
- measuring at least one parameter of the tablet.
