Provided is an overload prevention mechanism including a load receiving part provided with a flange having at least three ribs on the upper surface of the flange; a pedestal located below the load receiving part; an elastic body which has one end in contact with the load receiving part and the other end in contact with the pedestal, and which biases the load receiving part and the pedestal in such a direction that the load receiving part and the pedestal are separated from each other; and a connection member having on the lower surface thereof recessed grooves which engage with the ribs. The three or more ribs are disposed so as to restrict inclination and rattling of the load receiving part due to a load applied to the load receiving part.

A weighing scale has a measuring platform which is supported by at least three supporting feet resting on a floor, wherein to each supporting foot a load cell is assigned, wherein each load cell senses the share of the weight force originating from the measuring platform supported by the respective supporting foot. Each supporting foot is designed as a vertically extending measuring foot and comprises a load cell carrier on which the load cell rests and is attached, and an adjusting foot located below the load cell carrier. The load cell carrier is screwed with its external thread into the internal thread of the adjusting foot such that, by turning the adjusting foot relative to the load cell carrier, a vertical height of the measuring foot along a vertical screw axis is adjustable.

Noise that is present in the output of a weight sensor can lead to erroneous weight data. A moveable device, such as a tote, may be used by a customer while shopping in a facility. This tote can include one or more weight sensors that are used to determine the weight of items added to or removed from the tote. However, noise can affect the output of the weight sensors, where such noise is attributed to movement or vibration of the tote. Data from a vibration sensor or a motion sensor coupled to the tote can be analyzed to determine noise that is common to weight data and vibration data or motion data associated with the tote. This common noise can then be removed or attenuated from the weight signals to determine de-noised and valid weight data for the tote.

An offset weighing apparatus and method for use with poultry processing equipment includes a weigh assembly to weigh an animal connected to a shackle assembly as the shackle moves in contact with a force sensor along a conveyor line. A diverter assembly laterally displaces a shackle retaining the animal from below the conveyor line into engagement with the force sensor. The bending axis of the force sensor is approximately parallel to the displaced shackle. The angular position of the bending axis and shackle, and relative positions, friction, and forces of the components of the shackle assembly and weigh assembly are analyzed to calculate the weight of the animal connected to the shackle without removing the animal from the shackle or ceasing movement of the conveyor line.

A dynamic scale to achieves a higher throughput, by at least one of a spring steel sheet being installed in the travel direction of the first shaft of the first transport belt, and/or the control of the motors as well as the transmission of the sensor signals taking place via ribbon cables which are arranged parallel to the transport belts, and/or an electronic evaluation of interference oscillations of the signals of the sensors of the weighing cell takes place, within at least one lowpass filter being used, and wherein at least two digital notch filters are used.

In a dynamic scale and a weighing method therefor, an object to be weighed is received on a weighing unit of the dynamic scale and weight information of the object on the weighing unit is detected by the weighing unit. The weight information includes a number of items of weight information, which are supplied to a processor, and a derived weight value is determined in the processor by evaluation of a predetermined number of the items of weight information, and a quality value for the derived weight value is also determined in the processor by evaluation of the predetermined number of items of weight information. Depending on the quality value, it is established, in the processor, that the derived weight value is a valid weight value and, when it is established that the derived weight value is a valid weight value, the weighing unit is then fed with a new object.
