摘要： An apparatus and method which control the supply of a product to a pooling unit. A sensor is provided for sensing whether the product has been supplied to a preset level of the pooling unit. The method comprises sensing whether the product has been supplied to the preset level of the pooling unit. A first time period is measured until the preset level is attained once supply of the product has begun. A second time period is calculated and measured based on the first time period, during which the product continues to be supplied to the pooling unit. The supply of the product to the pooling unit is then halted in response to expiration of the second time period. Control is effected such that the overall amount of the product supplied is substantially constant irrespective of any variation in the amount of the product supplied to the pooling unit per unit time.

摘要： A system and method are disclosed that provide a specific volumetric output (e.g., product feed and discharge) of a material. In some implementations, these systems and methods are particularly suited for use with strand-type materials, namely, materials having difficult handling characteristics. For some implementations, a specific pile depth and width of a material is created on a moving belt to provide a specific volumetric output based on the speed of the belt. One or more leveling drums can be used to make the pile depth consistent. Moreover, a weighing system can be provided that is used in combination with the metering mechanism and other components (e.g., a control system) to create a “weight-loss” type weigh feeder.

摘要： A conveyor capacity control system includes a conveyor operative to receive granular material at a conveyor intake thereof and convey same to a conveyor discharge with a conveying device at a conveyor flow rate up to a maximum conveyor flow rate, and a granular material container with a container discharge opening oriented to discharge granular material from the granular material container into the conveyor intake, and a discharge gate movable to control a size of the container discharge opening. A flow rate control processor is operative to determine the maximum conveyor flow rate and detect when a discharge flow rate of granular material from the container discharge opening into the conveyor intake is greater than or less than the maximum conveyor flow rate, and increase or decrease the discharge flow rate to substantially coincide with the maximum conveyor flow rate. A hoist control is also provided for a truck box.

摘要： A gate-type feeder control system has level and weight sensors for monitoring the output of the system to a conveyor or other receiver, an electronic control circuit responsive to the sensors, and a hydraulic actuator circuit including a plurality of valves to provide the desired output of a feeder gate. In the electronic circuit, a master set point signal is entered and compared with the output signal from the sensors. The output flow to the receiver of the system is continuously adjusted by a deviation controller to reduce the deviation in these two signals. Erratic changes in system output are avoided by a deadband circuit introduced into the electronic circuitry to buffer excessive oscillation, overresponse and even instability caused by transient size change and lumping associated with bulk materials. The electronic circuit also includes an averaging module to average the level/weight of the material being discharged to obviate responding to peak levels. Finally, utilization of stepped sequencing and time delay of the solenoid valves also maintains a more accurate profile on the belt while minimizing shock. In the hydraulic circuit, power for opening and closing the feeder gate is provided through the use of power cylinders with pressurized fluid being supplied by a compensating, variable volume pump.
摘要翻译：门型馈送器控制系统具有液位和重量传感器，用于监测系统对输送机或其他接收器的输出，响应于传感器的电子控制电路以及包括多个阀以提供期望输出的液压致动器电路的馈线门。在电子电路中，输入主设定点信号并将其与来自传感器的输出信号进行比较。通过偏差控制器连续地调节到系统接收器的输出流量，以减少这两个信号的偏差。引入到电子电路中的死区电路可以避免系统输出的不正确变化，以缓冲由于瞬态尺寸变化和与散装材料相关联的结块引起的过度振荡，过度响应甚至不稳定性。电子电路还包括平均模块以平均被排出的材料的水平/重量以消除对峰值水平的响应。最后，使用阶梯式排序和电磁阀的时间延迟也可以在皮带上保持更准确的轮廓，同时最大限度地减少冲击。在液压回路中，通过使用具有加压流体的动力缸来提供用于打开和关闭进料器门的功率，该加压流体由补偿的可变容积泵供应。

摘要： The present invention relates to a guide unit for measurement acting as a guide for measuring the micro-weight of fine grains having minute weight and volume, such as powders, granules, seeds and pills, and to a micro-weight measuring system for accurately measuring the fine grains by a preset micro-weight by using the guide unit for measurement. The present invention has an effect of being capable of measuring the micro-weight as a unit to thereby package fine grains such as powders, granules, seeds and pills by micro-weight unit. In addition, the present invention has an effect of being capable of accurately measuring the fine grains by the preset micro-weight in such a manner that in the procedure of discharging a one-unit-micro-weight of the fine grains, some of the fine grains are discharged at a smaller amount than the initially-discharged amount and are finally discharged by dropping.

摘要： A device for selectively applying a test load to a weight-sensing control mechanism in an enclosed conveyor unit for feeding particulate material at a controlled rate. The weight-sensing mechanism continuously senses the weight of a variable quantity of material such as coal being conveyed through a predetermined reference zone and one or more load cells generate a voltage signal representative of the weight being sensed. The test load may be supported in the conveyor unit in either of two positions including a first position wherein it is supported independently of the weight-sensing mechanism and a second position wherein it is transferred to the weight-sensing mechanism for the purpose of calibration. The device includes a transverse shaft journaled in the conveyor unit and a pair of eccentric hubs mounted at opposite ends of the shaft, each hub being rotatably received in a connecting head portion of one of a pair of support rods adapted to suspend the test load. Thus, rotation of the shaft and eccentric hubs causes the test load to be transferred between its two positions so as to transfer the weight of the test load to the weight-sensing mechanism for the purpose of calibration. The transfer is accomplished by an operator at a location outside the enclosed conveyor unit.
