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 weighing method has an automatic micro-calibration function. In the method, an automatic adjustment is performed by a self-calibration weighing module. When the result of the adjustment does not meet a requirement, an automatic calibration is performed by the self-calibration weighing module, followed by weighing fine formulation materials. In the weighing method, the self-calibration module is used to perform the automatic calibration function to weigh the fine formulation materials. This provides a high degree of automation, and greatly reduced cost in equipment and labor for a formulating process, saving on time and labor, and with no risk of cross-contamination.

A weighing device includes a conveyance unit which conveys an article, a hopper which receives the article conveyed by the conveyance unit, temporarily holds the article, and then discharges the article downstream, a detection unit which detects the article between a conveyance end of the conveyance unit and the hopper, and a control unit which controls driving of the conveyance unit. When the detection unit does not detect the article at a start of driving of the conveyance unit, the control unit drives the conveyance unit for a first period. When the detection unit detects the article at a start of driving of the conveyance unit, the control unit drives the conveyance unit for a second period longer than the first period.

A combination weigher includes: a dispersion unit adapted to radially disperse food products dropped in from above and onto the dispersion unit; a plurality of V-shaped like guide structures extending radially away from a center of the dispersion unit and arranged such that a narrower end of the V-shaped like guide structures face a center point of the dispersion unit; a plurality of hoppers associated to each of the trenches arranged below the outfeed ends of the trenches; and a control unit; and screw feeders arranged in each of the trenches operated by the control unit. The space between adjacent V-shaped like guide structures at a distance R1 defines a buffer zone for radially dispersed food products from the dispersion unit. The screw feeders in the adjacent trenches have opposite orientation and rotate in opposite directions such that upper part of the screw feeders are rotating away from each other.

A dual-barrel powder dispenser is provided. The dual-barrel arrangement may offer a highly-accurate, and highly efficient system and method for dispensing a consistent amount of powder. A controller in communication with the interface may determine the speeds at which each barrel rotates in order to dispense a volume and weight of powder from a hopper to a receptacle. A scale may monitor and determine the total weight of powder dispensed into the receptacle resting on the scale. The entire assembly may be self-contained in a single integrated body.

Methods and systems for controlling a vibratory feeder are disclosed. In some embodiments, the methods and systems include the following: a controller module including a graphical user interface for selecting operating parameters to be communicated to a bowl drive that causes a feeder bowl to move, monitoring algorithms stored in non-transitory memory for processing motion data to monitor motion of the feeder bowl, and adjustment algorithms stored in non-transitory memory for determining and automatically adjusting the operating parameters, and a motion sensor module configured to mount with and sense motion of the bowl drive, the motion sensor module including an accelerometer, a digital signal processor (DSP) microcontroller, and a transmitter. The DSP microcontroller samples output data from the accelerometer, determines motion data of the motion of the bowl drive, and transmits the motion data via the transmitter to the controller module.

The electronic balance is configured to be capable of performing the following series of operations (I) to (VII) automatically: (I) The opening and closing mechanism opens the door. (II) The moving up/down mechanism applies the load of the built-in weight to the weighing mechanism. (III) The opening and closing mechanism closes the door. (IV) After a predetermined period of time elapses, the opening and closing mechanism opens the door. (V) The moving up/down mechanism removes the load of the built-in weight from the weighing mechanism. (VI) The opening and closing mechanism closes the door. (VII) The control unit performs zero-point adjustment of the weighed value. Accordingly, operation of preliminary loading is automatically performed, and thus the stability of the weighing accuracy is improved.
