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.

An air condition service machine for charging an air conditioner with refrigerant in a fast-charge mode, the fast-charge mode controlled based upon the changing weight rate of a refrigerant tank providing the supply of refrigerant to the air conditioner. The embodiment may also include a compensation mode to provide greater accuracy of the charge after completion of the fast-charge mode. The rate of refrigerant flow is monitored and an end time as opposed to weight target ends the charge.

A weighing apparatus for weighing batches of food product is provided. The weighing apparatus comprises a product supply unit arranged to supply food product to be weighed, a weighing unit arranged to receive and weigh a batch of food product, and a product delivery unit arranged to receive the food product from the product supply unit and to deliver a batch of food product to the weighing unit. The product delivery unit comprises a trough extending between a product supply position, at which food product is received from the product supply unit, and a product delivery position, at which the food product is delivered for receipt in the weighing unit, and a transport screw arranged in the trough and configured to rotate in the trough for conveying food product from the product supply position to the product delivery position. The transport screw comprises at least two helical members. A primary helical member extends along a length of the trough substantially from the product supply position to the product delivery position. A secondary helical member extends along a length of the trough substantially from the product supply position to a termination position of the secondary helical member, the termination position of the secondary helical member being between the product supply position and the product delivery position.

An exemplary dispenser includes a housing and a refill unit. The refill unit being removable and replaceable. The dispenser also includes a processor, memory, a dose count stored in memory that is indicative of the number of doses in a full refill unit, a level sensor for detecting a predetermined level the refill unit and a dispense count indicative of the number doses of product dispensed from the refill unit. In addition, the dispenser includes memory and has logic stored in the memory for recalibrating the number of doses remaining in the refill unit as a function of the dose count, the number of doses of product dispensed and the predetermined level of product. The number of doses of product remaining in the refill unit may be displayed on the dispenser, on a remote station, or on both the dispenser and a remote station.

Concentrate filling system includes a solid loader operable to dispense particles through a dispensing end. The system includes a conveyer operable to receive the dispensed particles at a proximal end and further dispense particles at a distal end. The system includes load cell operable to receive a container that receives the dispensed particles. The system includes an injection pump to dispense fluids into the container. The system includes controller operable to receive data from the load cell indicative of a weight of the particles and/or fluid and send a control signal to the conveyor to adjust the dispensing of the particles and send a control signal to the injection pump. Upon receiving indicative of a predetermined weight of the container, fluid, and particles, the controller is operable to send a control signal to the conveyor and the injection pump to stop dispensing of particles and fluid.

An automated hopper and belt conveyor apparatus that can be used to feed bulk material into a mixer in order to create a feed mixture for farm animals. The automated hopper and belt conveyor apparatus includes a support frame that supports a hopper and an inclined belt conveyor that operate under control of a controller to accurately feed a desired quantity (in weight) of a bulk material item from the hopper to the mixer by forward-direction operation of the inclined belt conveyor. Excess bulk material that has been loaded into the hopper (bulk material over the desired quantity in weight) is reclaimed by the controller controlling opening a rear gate of the hopper and reverse-direction operation of the inclined belt conveyor.

The present disclosure relates to the technical field of coal-fired power plant equipment, in particular to a PLC coal machine control system, including a PLC control unit, a weighing unit one, a weighing unit two, a drive unit, a frequency converter, a belt motor and a velocity measuring unit; wherein the PLC control unit is electrically connected to the weighing units one and two, for making a real-time collection of weight values of the two units; and the PLC control unit is electrically connected to the drive unit, frequency converter and velocity measuring unit, for making a real-time collection of output signals of the drive unit, velocities of the frequency converter and velocities detected by the velocity measuring unit. According to the present disclosure, the PLC controller is employed to process signals, so that the stability of the system is improved and stable operation of a generator set is guaranteed.

The method according to the invention provides a way to continue gravimetric weighing of bulk material during refilling of a gravimetric metered dispensing unit, and to determine the mass of the refilled bulk material using a refilling container during the filling operation material and so determine the actual mass flow discharged during refilling in real time or on average in order to adjust it to a target mass flow.

An air condition service machine for charging an air conditioner with refrigerant in a fast-charge mode, the fast-charge mode controlled based upon the changing weight rate of a refrigerant tank providing the supply of refrigerant to the air conditioner. The embodiment may also include a compensation mode to provide greater accuracy of the charge after completion of the fast-charge mode. The rate of refrigerant flow is monitored and an end time as opposed to weight target ends the charge.
