Abstract
A testing apparatus has at least one sensor for detecting foreign bodies in a container to be tested. The at least one sensor and/or at least one carrier element receiving the container are movable between a first arrangement and a second arrangement. In the first arrangement, the at least one sensor is arranged at a distance in the movement direction from the container. In the second arrangement, the at least one sensor encloses the container at least partially.
Claims15
A testing apparatus for a packaging machine for packaging ingestible products in containers, wherein the testing apparatus comprises:
- a conveyor device, which is configured to convey a plurality of containers in a clocked manner in a conveying plane in a conveying direction through the testing apparatus;
- and
- at least one sensor, which is arranged in a testing region of the testing apparatus and which is configured to detect foreign bodies in a container to be tested among the plurality of containers;
- wherein the at least one sensor and/or at least one carrier element of the testing apparatus, by which the container to be tested is received in the testing region, is configured to be movable such that a relative movement between the at least one sensor and the container to be tested can be generated in a movement direction between a first arrangement and a second arrangement, the movement direction being orientated perpendicularly to the conveying plane;
- wherein, in the first arrangement, the at least one sensor is arranged at a distance in the movement direction from the container to be tested and, in the second arrangement, the at least one sensor encloses the container to be tested at least partially.
A method for testing containers for ingestible products, wherein the method comprises the steps of:
- a) feeding a plurality of containers in a clocked manner in a conveying plane in a conveying direction;
- b) arranging a container to be tested of the plurality of containers in a testing region in a first arrangement relative to at least one sensor for detecting foreign bodies, the at least one sensor being arranged at a distance in a movement direction from the container to be tested in the first arrangement, the movement direction being orientated perpendicularly to the conveying plane;
- c) generating a first relative movement between the container to be tested and the at least one sensor in the movement direction from the first arrangement into a second arrangement, in which the at least one sensor at least partially encloses the container to be tested;
- d) detecting by means of the at least one sensor whether a foreign body is contained in the container to be tested, and thereby testing the container;
- e) generating a second relative movement between the tested container and the at least one sensor parallel to the movement direction back into the first arrangement;
- and
- f) feeding the tested container from the testing region.
