摘要： A diverting checkweigher comprising a conveyor belt with product-carrying, vertically floating slats that are supported on a weigh scale as the belt passes over it. The floating slats isolate product weight from belt weight. The slats themselves may be laterally stationary or divertible. If divertable, they can divert products based on their weights. If not divertible, the slats can be used with product pushers to divert products for weight-based sorting or rejection. The slats have legs that extend below the bottom of the belt to ride on the scale or be diverted across the belt by a diverter. The pushers are diverted by a diverter.

摘要： In a dynamic scale and control method for flat goods transported on their sides, use an input-side first assembly for thickness measurement, a transport device having transport belts arranged on a weighing plate. A control processor starts a length measurement and the driving of the transport belts, and starts a thickness measurement and implement a dynamic weighing process during the transport of a first flat good. A next flat good is supplied to the input of the dynamic scale if a valid weight measurement result is present for the predecessor good, and ejection of the predecessor good or end of the weight measurement occur if a third sensor at the input of a takeoff device of the dynamic scale detects the leading edge of the predecessor good, and a check yields that no valid weight measurement result is present for the predecessor good.

摘要： In a method and apparatus for length measurement of a flat good in a goods processing system having first and second stations, each having a sensor in the transport direction of the flat good, a control processor implements a path control and counts encoder pulses of an encoder in the first station. An event is determined by the sensor of the second station, and an associated numerical value Z1 of the encoder pulses is stored in the control processor, as is a numerical value Z2 for a distance between the two sensors is also stored. An additional event is determined by the sensor of the first station, and an associated numerical value Z3 of the encoder pulses is stored. As soon as both events are present, Z2 and the difference Δ=Z3−Z1 are added by the control processor, and the sum is used to designate the length.

摘要： The static or dynamic weighing apparatus for weighing an object or item, comprising a weighing assembly that includes a base with four (4) load cells attached to it, two (2) active load cells and two (2) passive load cells. Each active load cell has a mounting side and a weighing side. They are mounted to the base and to each other via a rigid weighing platform and are rotated 180° with respect to each other in the horizontal plane, thereby generating respective inverse error signals when an object or item is placed on or passes over the weighing platform. The two (2) passive load cells are mounted in the same manner. A combination of the voltage outputs from each of the respective two (2) load cells pairs negates all horizontally and vertically induced errors thus yielding a highly accurate two (2) times normal weight signal of the object or item being weighed. Error voltages felt by the passive assembly, representing any present vertical vibration, is removed via electrical circuitry from the actual active weighing voltage output, resulting in a true weight of the object or item being weighed. The resulting output voltage over the designated time interval then represents the true weight of the object or item being weighed. A voltage-to-frequency converter is employed to transmit the corrected true frequency output due to the actual analog output voltage resulting from the active weight being measured to a binary counter over a pre-specified time period. By counting a pulse train that varies directly to the applied voltage over a specified period of time results in a natural averaging weight and the resulting count is the average and true count of the representative weight of the object or item being weighed.

摘要： The present invention is a method and apparatus which automates the weight measurement of a payload in conjunction with a roller bed based loading/unloading station. The apparatus is designed as a retrofit for an existing loading station and consists a stationary frame mounted underneath the roller bed loading station. The apparatus includes lifters which are raised by air cylinders or the equivalent upon activation to physically remove the payload temporarily from the roller bar station while the weight is measured through load cells arranged with the lifters. The engagement and release of the lifters as well as the reading of information from the load cells is coordinated and controlled by a microprocessor. Appropriate communication means are provided for, to enable the system to be activated, and to allow the weight readings taken to be incorporated into other payload management functions such as billing, receiving, inventory control, or other functions. The system is further characterized by visual or audible alarms to prevent the system from being overloaded and to signal to an operator when it is safe to remove the payload or place an additional payload on the roller bed.
