ARTICLE STACKING ASSEMBLY AND ITS CALIBRATING METHOD

摘要

A method of calibrating an article stacking device position detector (22) for an article stacking device (1) having at least one article receiving compartment (5) and being movable in a cyclic manner to transfer an article received in the or one of the compartments of the stacking device at an article receiving position (19) to an article stacking position at which the article is stacked. The method comprises: i) positioning the article stacking device (1) at a predetermined position relative to the article receiving position (19); ii) causing the position detector (22) to monitor movement of the article stacking device until a datum indication (34) is sensed; and iii) storing a calibration value representing the amount of movement of the article stacking device between the predetermined position and its position when the datum indication (34) was sensed.
