A checkweigher assembly includes a frame that is rotatable about an axis of rotation, a scale operatively connected with the frame, and a holder member operatively connected with the scale. The holder member is substantially supported by the scale. The holder member includes first and second grip members, each having an outer surface. The outer surfaces of the first and second grip members are arranged in a face-to-face relationship and are axially spaced apart by a gap. The first grip member is movable from a first position to a second position. The gap is defined by a first minimum length when the first grip member is in the first position and a second minimum length when the first grip member is in the second position, wherein first minimum length is greater than the second minimum length. A method of weighing objects with the checkweigher assembly is provided.

A mass measuring apparatus includes a transferring and gripping device for removing an article from a seat of a movement device, holding the article in a measuring position, and then reinserting the article into the seat. The transferring and gripping device includes a gripping element for holding the article, an actuator for operating with an actuating signal on the gripping element to make the gripping element vibrate at a specific resonance frequency, a sensor for measuring a vibration response signal of the gripping element vibrating and supporting the article in the measuring position, a processing unit for receiving the vibration response signal and controlling the actuator to generate an actuating signal to make the gripping element vibrate at an operating resonance frequency, and then calculating a mass of the article by comparing the operating resonance frequency with the resonance frequency of the gripping element.

A presence sensor combined to a first storage carrier for detecting a presence of a second storage carrier. A load cell measures the weight of the material expelled from the first storage carrier. A scale controller in communication with the presence sensor responds to the presence of the second storage carrier by recording of the weight measurement from the load cell.

An apparatus and method for filling a container with fragile fruit involving submerging the container in water to better distribute the fragile fruit within the container. The container may be filled with fragile fruit either before or after being submerged in water. The fragile fruit may be transported using a stream of water or other suitable fluid medium.

A method and a system measure interfering influences on a checkweighing device. In the method, external interference data are obtained, as are interference data from the checkweighing device itself and interference data from an object being weighed, by calculating or mapping the weighing error data in the stationary state, in the operating state, and in the weighing state. The system for measuring the interference uses a meter and a processing apparatus. The meter and the processing apparatus perform an interference measurement and a compensation method. The amount of interference in the checkweighing device in each state and the amount of influence of the interference on the weighing performance is obtained, thereby facilitating the production, debugging, maintenance, and use of a checkweighing device.

A system including a flume. The flume can include a fluid and be configured to receive crops. The system also can include crop selectors each sized to move the crops individually from the flume into a scale. The system additionally can include the scale. The scale can be configured to weigh the crops while the crops are in the scale. The system further can include a container carrier configured to (i) hold a container that is submerged in the fluid while the crops are dumped from the scale into the container and (ii) lift the container out of the fluid to allow the fluid to drain from the container while the container holds the crops. Other embodiments are described.
