A filling device (10) for filling a barrel with a liquid comprises: a before-filling barrel weight measurement means (12) for measuring a weight of an empty barrel (40) before a liquid is filled into the barrel; a deviation calculation means (31) for calculating deviation by subtracting a predetermined before-filling barrel reference weight from the weight of the before-filling barrel which is measured by the before-filling barrel weight measurement means; a liquid filling means (21) for filling a liquid, the weight of which is predetermined, into the before-filling barrel; an after-filling barrel weight measurement means (17) for measuring a weight of the after-filling barrel after the liquid was filled by the liquid filling means; and an after-filling barrel correction weight calculation means (17') for calculating a correction weight in which an absolute value of the deviation is added to the weight of the after-filling barrel weight in the case where the deviation calculated by the deviation calculation means is negative. Due to the above constitution, even when the weight of barrels deviate, a necessary amount of liquid such as beer can be filled into a barrel.

A method of selecting eggs is disclosed. The method includes the step of: selecting a predetermined target number of eggs from a plurality of eggs which are individually weighed in advance and are being conveyed in a row, in such a manner that the individual weight of each selected egg may fit within a predetermined permissible unit weight range and also that the total weight of the group of selected eggs may fit within a predetermined permissible sum total weight range including a target sum total weight. Until the number of selected eggs reaches a set number, an egg is selected as one of the predetermined target number of eggs if the weight of the egg fits within the predetermined permissible unit weight range; and after the number of selected eggs has reached said set number, a further egg is selected as another one of the predetermined target number of eggs if the weight of the further egg falls within said predetermined permissible unit weight range and if a subtotal weight resulting from addition of the weight of the further egg to the total weight of the previously selected eggs falls within a selective permissible weight range which becomes narrower with increase in the number of selected eggs.

An apparatus for automatically and accurately weighing powder material comprises powder containers (8) containing powder materials to be weighed, powder cups (1) for receiving powder material from the powder containers and means (15) for automatically feeding the powder material from one of the powder container to one of the weighing cups through a feeder. To enable different powders to be fed, each powder container (8) is integrally provided with the feeder (22) so that one powder material fed into the weighing cup through the feeder is prevented from contaminating with other powder material and therefore the powder material can be accurately weighed.

摘要:
A kind of automatic rotary weighing and packing machine having a plurality of weighers (1-8) radially or annularly arranged on a circular rotary table (10) for automatically effecting such processes as filling of product, weighing and judgement at respective positions around the table, which is especially suitable in the case where the product to be packed is sticky granular or powdered bulk material and the packing container is a bag or the like. This machine uses no weigh hopper or backet in which sticky product is liable to remain to cause weight error and the packing container is held by a holding mechanism (12) attached to each weigher (1-8) and directly filled with product, which is then weighed and sealed. A fixed amount feeding device (24) is used for feeding product in the container (16) and it is throughout controlled, based upon the result of weighment for keeping the weight of product packed in each container always at a predetermined value.
摘要:
A package fill height detector comprises a probe (36) for abutting a batch of product in a package (11A), means for inserting the probe into an opening in the top of the package so that the probe rests on the product, and a sensor (53) for sensing the height of the probe when it rests on the product in the package to determine the fill height of the package. The means for inserting the probe into the package comprises an arm (52) which supports the probe, a motor for rotating the arm and a cam (37) for guiding the arm downwardly into the package until the probe rests on the product within the package and then upwardly out of the package. An associated weighing and packaging system includes a control coupled to the sensor for decreasing the delivered weight of subsequent batches of product when the fill height is below a target level and vice versa.
