A multihead weigher with a collector for feeding, weighing and collecting solid food products with a sticky coating. The multihead weigher has a number of receptacles for weighing the solid food products and discharging the solid food product to the collector. Each receptacle having a scraper for scraping the surface of the receptacle when the solid food product is being discharged from the receptacle into the collector.

A combination weighing apparatus including a plurality of units arranged to form a circumference in a horizontal direction, wherein the plurality of units include weighing hoppers, each of which holds, weighs and discharges the object. The combination weighing apparatus comprises at least one small unit and at least one large unit, and: each of the weighing hoppers is a single-chamber weighing hopper or a double-chamber weighing hopper, the small unit includes the single-chamber weighing hopper and does not include the double-chamber weighing hopper, and the large unit includes the double-chamber weighing hopper and does not include the single-chamber weighing hopper; and/or some of the plurality of units include memory hoppers each of which is disposed below the weighing hopper, holds the objects discharged from the weighing hopper and discharges the objects, the small unit does not include the memory hopper, and the large unit includes the memory hopper.

Avoiding the discharge of lightweight articles as much as possible while improving the yield. A combination weighing device (1) comprises: a transport unit (10, 11) configured to transport an article (100) supplied from an outside; a plurality of hoppers (13) configured to perform a measurement while temporarily holding the article (100) transported by the transport unit (10, 11) to acquire a mass value of the article (100); and a controller (5) configured to select a combination of the hoppers (13) to discharge the article (100) from the hopper (13) included in the selected combination based on a target mass value set in advance and the mass value acquired in each of the plurality of hoppers (13). The target mass value is a value obtained by adding a correction value to a mass value requested by a user, and the correction value is set to a different value depending on a number of the hoppers (13) used for the combination.

A product output device for a product supply system, in which a first product supply device and a second product supply device provide product amounts in a first collecting container and a second collecting container. Both collecting containers are provided with respective first closure flaps and second closure flaps. As soon as the collecting containers are positioned above the product receiving device, the closure flaps can open in order to drop the product into the product receiving device. The collecting container, comprising the first collecting container and the second collecting container, can be pivoted to an output position of the first collecting container, or to a output position of the second collecting container. Herein, the pivoting movement to the respectively different output positions begins before the first closure flaps have closed.

A gravimetric metering device which is provided to add an additive material to a polymer material, includes: a hopper to contain the additive material, a supply member to transport the additive material discharged from the hopper towards the polymer material, and first and a second weighing elements to detect the weight of the additive material discharged from the gravimetric metering device.

A control unit determines, on the basis of the weight detected by the first weighing element, the flow rate of additive material discharged from the gravimetric metering device by regulating the supply member and controls the operation of the first weighing element by means of the second weighing element by comparing, at the start and at the end of a cycle for charging the hopper with the additive material, the weight detected by the first weighing element with the weight detected by the second weighing element.

A gravimetric metering device which is provided to add an additive material to a polymer material includes a hopper which to contain the additive material and a supply member which is provided downstream of the hopper in order to receive the additive material which is discharged from the hopper and to transport it towards a discharge opening which is connected to the polymer material, and a first and second weighing element which are provided to detect the weight of the additive material which is discharged from the gravimetric metering device.

The first weighing element is configured to detect a weight within a first maximum weighing range while the second weighing element is configured to detect a weight within a second maximum weighing range different from the first maximum weighing range.
