GNSS guidance and machine control

A global navigation satellite sensor system (GNSS) and gyroscope control system for vehicle steering control comprising a GNSS receiver and antennas at a fixed spacing to determine a vehicle position, velocity and at least one of a heading angle, a pitch angle and a roll angle based on carrier phase position differences. The roll angle facilitates correction of the lateral motion induced position errors resultant from motion of the antennae as the vehicle moves based on an offset to ground and the roll angle. The system also includes a control system configured to receive the vehicle position, heading, and at least one of roll and pitch, and configured to generate a steering command to a vehicle steering system. The system includes gyroscopes for determining system attitude change with respect to multiple axes for integrating with GNSS-derived positioning information to determine vehicle position, velocity, rate-of-turn, attitude and other operating characteristics. A vehicle control method includes the steps of computing a position and a heading for the vehicle using GNSS positioning and a rate gyro for determining vehicle attitude, which is used for generating a steering command. Alternative aspects include multiple-antenna GNSS guidance methods for high-dynamic roll compensation, real-time kinematic (RTK) using single-frequency (L1) receivers, fixed and moving baselines between antennas, multi-position GNSS tail guidance (“breadcrumb following”) for crosstrack error correction, guiding multiple vehicles and pieces of equipment relative to each other and earth-moving equipment and method applications.

Fluid filling system with fill time optimization

A fluid filling system is disclosed wherein containers to be filled with fluid materials are supplied first to one or more time-metered filling stations, and then to a weight-metered filling station. At first, the time-metered filling station(s) is / are inactive, and only the weight-metered filling station is used to fill a first container to a desired final weight. A timer is used to monitor the filling time necessary to reach the desired final weight. When later containers are then supplied to the time-metered filling station(s), they are filled at each time-metered station for a filling time which is dependent on the previously measured filling time for the weight-metered filling station. These containers are then "topped off" by the weight-metered filling station to precisely fill them to the desired final weight, and the time required for such topping off is measured for use in subsequent modification of the filling times at the time-metered filling stations. For each container, the filling time at each time-metered filling station is dependent on the filling time at the weight-metered filling station in such a manner that the two will converge towards each other with successive containers until they are substantially or exactly equal. Preferably, the dependence between the time-metered filling time and weight-metered filling time are such that ttimed(t)=tN(t-1)+Qx[tN(t-1)-ttimed(t-1)]wherein tN(t-1) is the filling time at the weight-metering filling station for a prior container; ttimed(t) is the filling time at the time-metering filling station for the prior container; ttimed(t-1) is the filling time at the time-metering filling station for the prior container; Q is a predetermined real number.

Sterile filling valve

The invention discloses a sterile filling valve applied to a sterile cold filling production line of beverage products. The filling valve comprises a material flowing cavity channel, and a valve opening and closing device is combined with a valve body into a whole, and the valve opening and closing device and the valve body are completely separated into two parts by an air and liquid separation film. The design guarantees the sanitation requirement of the sterile filling, and reduces the interference on the material flowing by the complicated design, so the material is favorable to flow, and the cavity channel is convenient to clean in all directions. The filling valve is integrally arranged on a mounting hole of a rotary table of a filling machine, and pairwise pressed by press plates, sothe valve can be conveniently mounted and detached. A pipeline of the filling valve is provided with an electromagnetic flow meter and a metal film valve for accurately controlling the filling accuracy. The valve adopts the filling method of not contacting bottle openings, so the pollution can not be caused even if the polluted bottles exist. Various functions of accurate filling of various levels, filling under the condition of bottle existence, no filling under the condition of no bottle, filling stop under the condition of bottle fulfillment, and the like can be realized by a filling control unit.

Mobile fluid product filling system with fast setup

InactiveUS6595250B1Fast shut-down and start-up timeReduce maintenanceSolid materialLiquid materialMechanical engineering
A fluid filling system has a filling unit which is repositionable with respect to a filling station. The filling unit includes a filling head and a dispensing switch. The filling station has a filling position at which a container may be placed for filling with fluid. A container fill sensor is provided at the filling position so that it may detect the degree to which a container is filled. A movable switching member is also provided on the filling station, and it communicates with the container fill sensor and moves to different positions in accordance with the degree to which a container at the filling position is filled. The filling unit is repositionable with respect to the filling station so that the filling unit may be situated adjacent the filling station with its filling head situated over the filling position, or may be moved to allow the filling unit to rest at other locations. When the filling unit is resting adjacent the filling station with its filling head situated over the filling position (i.e., when it is in the ready-to-fill position), the switching member and dispensing switch are adjacently situated between the filling unit and filling station so that the switching member may actuate the dispensing switch. Thus, when the container fill sensor detects that container filling is to occur (or is to cease), the switching member is actuated, which in turn actuates the dispensing switch to change the filling head between its filling state and its nonflow state in accordance with the filling detected by the container fill sensor.
