Weighing pan for weighing batches of products and a combination weighing machine equipped with a number of such weighing pans

摘要

A weighing pan 17 for weighing subportions of products to be packaged batchwise, in particular for use in combination weighing of irregularly shaped and comparatively fragile commodities of fruits and vegetables. The pan has a discharge opening covered by a front wall and which is opened by a pivot movement of a bottom flap (1) between a products collecting position and a discharging position. The weighing pan is designed to collect individual product units substantially arranged in a single row on the bottom flap (1) and the bottom flap (1) extending throughout the length of the weighing pan slopes downwardly in the discharging position towards the discharge opening at such an angle that the collected product units are discharged by a substantially sliding movement. The invention includes a combination weighing machine comprising a number of weighing pans (17) with a stop member (23) common to the weighing pans (17) extending along the discharge openings of the weighing pans (17), said stop member being associated with the receiver conveyor and being movable transversely thereto from a position in which it covers the discharge openings of the weighing pans (17), to a second position at the other side of the receiver conveyor (19, 20), and from there back to the initial position along a path above the subportions discharged on the receiver conveyor.
