Sick have developed the DWS510-static combined volume measurement and weighing system for acquiring complete data (volume, weight and ID) on the consignments of courier, express and package service providers (CEP) as well as in logistics centres. Intended for low and medium throughputs of up to 500 units of freight per hour, it provides relevant data for freight calculations or for creating transport documentation. It consists of VMS510 volume measurement system, a rugged static weighing system and a hand-held reading device for the code information, integrated in a stable mechanical structure.
The VMS510 sensor head with integrated evaluation is mounted on a linear axle and moves above an immobile object to measure it. It transmits a fan-shaped laser beam whose time-of-flight is evaluated to within a few millimetres in the sensor head, providing information on the length, height and width of a cuboid item of freight. Objects with a minimum size of 50 x 50 x 50 mm³ can be measured.
During the volume determination, a weighing system integrated in the load-carrying surface measures the weight of the object. The functional principle of the weighing system is rugged. Thus, for example, a deviation from the horizontal of ±5° is permissible without leading to a spurious measurement.
The entire measurement process is triggered by scanning the bar code on the object. The Sick hand-held scanner provides a valid read. The result of the weighing process is called up and the drive of the linear axle started for the volume measurement.
The DWS510-Static combined volume measurement and weighing system allows rapid construction and commissioning. In addition, its modular structure permits adaptation to particular customer requirements. In operation, the measurement system offers accuracy and availability. Connection to the customer’s database takes place through Sick’s modular MSC800 system controller, which collects the data of a measurement process and combines them to form a data set. This compact controller offers a serial RS-232 interface and an Ethernet connection for transmission of measurement data to customers.
The development and design of the DWS510-Static combined volume measurement and weighing system is oriented upon international standards and legislative definitions (OIML, MID, national regulations). Thus, for example, all measurement results are stored in the calibration-enabled data memory of the MSC800 before they are made available at the customer interface. Based on the existing certificates for volume measurement and the scales, corresponding documents will be available for the DWS510-Static combined volume measurement and weighing system.
In the CEP and transport sector, apart from the weight, it is the size of the packages or pallets that determines the number of units that can be loaded onto a truck. Whereby the equation ‘low weight = small package size or small pallet load’ is frequently incorrect. Furthermore, in many segments of distribution logistics, volume is one of the relevant values for invoicing by transport service providers. The DWS510-Static combined volume measurement and weighing system optimises cargo space utilisation while simultaneously carrying out the invoicing of transport and distribution performance on the basis of the unit numbers, volumes and weights transported.
