A weight sensor unit, comprises a weight sensor configured to output weight sensor readings indicative of the weight being supported thereby. A transmission device is configured to transmit wireless signals, and a processor, is coupled to the weight sensor and to the transmission device. The weight sensor unit includes a battery. The weight sensor, transmission device and processor are powered by the battery. In use, the processor is configured to receive one or more weight sensor readings output by the weight sensor, and transmit the weight sensor readings wirelessly using the transmission device. The weight sensor unit may include a wireless transceiver configured to wirelessly interact with devices placed in proximity thereto. In an embodiment, all electronic components of the weight sensor unit are powered by the battery. A dispensing unit incorporating the weight sensor unit is also disclosed.

According to one aspect of the disclosure, a bulk material handling method includes receiving bulk material on a first level of a system at receiving stations equipped with dust control filtration equipment, pneumatically conveying the bulk material up to a third level into bulk material storage hoppers, storing the bulk material, dispensing the stored bulk material to a bulk material transporter on the first level, including dosing the stored bulk material to an interior of a bulk material dosing hopper to create a bulk material dose, docking the dosing hopper with the transporter via a docking apparatus, and releasing the dose into the interior of the transporter, through a reduced pressure region in an internal volume of the docking apparatus. Other disclosed aspects include a related system, subsystems, and apparatuses.

A precision measurement device includes a housing and a rotor. A feed inlet is provided at an upper side of the housing. A discharge outlet is provided at a lower side of the housing. The rotor is connected to a motor. Three rings of measurement recesses are formed on the outer wall of the rotor in correspondence with the feed inlet and the discharge outlet. An upper end of the feed inlet has a trapezoid shape which is narrow at the top and wide at the bottom. The discharge outlet is disposed off-center at an ascending position of the rotation cylinder, achieving an accurate measurement effect.

A system of detecting loading and unloading of mobile containers such as grain carts utilizes two low pass filters to determine whether the contents of the container are changing by subtracting one filter signal from the other, and using the sign of the difference. Weighing performance is improved by utilizing accelerometers to compensate for measurement dynamics and non-level orientation. Failure and degradation of weight sensors is detected by testing sensor half bridges. Loading and unloading weights can be tied to specific vehicles by utilizing RF beacons.

A cigarette rolling machine deposits uniformly metered charges of smoking material into a trough formed in a belt as dispensed from a bulk supply. A length of smoking paper sufficient for the combined length of two cigarettes is deposited nearby on the belt on a movable platen. As the platen moves, the belt glides over a fixed arbor and at least one other movable arbor, and the belt forms into a bight, rolling the material into a cylindrical volume. Filters are delivered and abutted to the ends of the volume and the smoking paper is entrained into the bight to encircle the smoking material and filters. A pre-moistened adhesive along a leading edge of the paper adheres to its trailing edge as a circular ouroboros and forming a tube. The twinned pair of cigarettes is then drawn across a cutting plane knife and parted into two individual cigarettes.

A conveyance mechanism (1) includes: a conveyance face (10) for conveyance of a plurality of articles having adhesion. The conveyance face includes: a first conveyance face (11); a second conveyance face (12) disposed downstream (D2) of the first conveyance face (11) in a conveyance direction (MD); and a protrusion (15) disposed between the first conveyance face and the second conveyance face, the protrusion protruding to space in which the plurality of articles glides. The protrusion protrudes beyond a first extension line (FL1) extending downstream in the conveyance direction along the first conveyance face, and protrudes beyond a second extension line (FL2) extending upstream in the conveyance direction along the second conveyance face.

The object of the present invention is to provide a novel conveying device with which it is possible to easily adjust a conveying amount of articles in a trough using a restricting plate, and a combination weighing apparatus having the conveying device. A conveying device to convey articles in a trough has a restricting plate to restrict a flow of the articles in the trough and the angle at which the restricting plate faces the articles is variable. With this configuration, there is no need to prepare a plurality of restricting plates that have different shapes and materials or to exchange such a plurality of restricting plates in the same manner as in a conventional device because the conveying amount in the trough can be adjusted merely by varying the angle at which the restricting plate faces the articles.

The hopper body has a third sidewall and a fourth sidewall that face each other in a second direction intersecting with the first direction and that connect between the first sidewall and the second sidewall, and a first corner portion adjacent to the distal end portion of the trough in the third sidewall and a second corner portion adjacent to the distal end portion of the trough in the fourth sidewall are bent in direction away from the distal end portion of the trough and also a first edge portion adjacent to the distal end portion of the trough in the first corner portion and a second edge portion adjacent to the distal end portion of the trough in the second corner portion are bent in direction closer to the distal end portion of the trough.
