Various embodiments are directed to methods and apparatuses for determining a weight of one or more objects disposed about an area of the weight measurement device using a single force sensor to accurately measure a force generated by the one or more objects. In various embodiments, the apparatus comprises a housing, a receiving tray, a lever assembly configured to receive a weight force from the receiving tray and generate a collective lever force corresponding to the weight force, the lever assembly comprising a plurality of levers, wherein each lever of the plurality of levers being at least substantially fixed to the housing at a first lever location and configured to receive a partial weight force from the receiving tray at a second lever location, and a force sensor configured to define a fulcrum point along each of the plurality of levers.

A weighing apparatus includes a first weighing device including a weighing platform and a second weighing device including a weighing platform located adjacent the first weighing platform. A small end fixture assembly is supported on the weighing platform of the first weighing device that supports a small end of a connecting rod thereon at a location spaced above the weighing platform of the first weighing device. A large end fixture assembly is supported on the weighing platform of the second weighing device that supports a large end of the connecting rod thereon at a location spaced above the weighing platform of the second weighing device.

Provided is a mass sensor including a four-corner-adjusting-mechanism capable of reducing the sensitivity of four-corner adjustment without reducing the rigidity of a Roberval mechanism. A mass sensor (1) includes a Roberval mechanism (2) in which a floating frame (21) and a fixing frame (22) are connected by upper and lower sub-frames (23, 24) having thin portions (23b) formed thereon, and a four-corner-adjusting-mechanism (4) to perform parallelism adjustment. The four-corner-adjusting-mechanism (4) includes an adjusting screw (41), and an upper elastic member (42u) and a lower elastic member (42d) disposed in series in the vertical direction so as to sandwich the sub-frame (23) to be subjected to parallelism adjustment.

A parallel-guiding mechanism in accordance with the present invention comprises a load-receiving portion for receiving a load of a to be weighed object; a fixing portion including an end portion, an extending portion extending forwardly from the end portion and mounting portions extending forwardly from the extending portion, and parallel-guiding members connecting the load-receiving portion to the fixing portion. The mounting portions include a first mounting portion and a second mounting portion. A receiving space is formed between the first mounting portion, the second mounting portion and the extending portion for receiving at least a portion of the load-receiving portion. A containing space for receiving the extending portion is formed between the parallel-guiding members, the load-receiving portion and the end portion. The parallel-guiding members include an upper parallel-guiding member and a lower parallel-guiding member. The load-receiving portion, the fixing portion and the parallel-guiding members are formed integrally of one piece of solid material.

Bucket (1) for transporting and unloading products, comprising an opening at the top for receiving the products and a collapsible hinged lid (2) at the bottom of the bucket (1), the lid (2) being connected to actuation means (3 to 6) capable of moving the lid (2) between a closed and an open position for the unloading of the products by means of gravity. The lid (2) comprises at least a side support wall (2a) in motion with said lid (2) and positioned adjacent to an inner (1a) wall of the bucket (1), said support wall (2a) being intended to drive the products outward by means of friction during the opening motion of the lid (2), the lid (2) being actuated in a controlled manner by said actuation means (3 to 6) along its opening path and subsequent closing path.
