Description

Goods size detection device and warehouse system
Technical Field
The invention relates to the technical field of cargo storage, in particular to a cargo size detection device and a storage system.
Background
With the progress of the age, intelligent logistics warehouse systems are being widely used. The intelligent logistics warehouse system comprises a warehouse management system, a warehouse control system, automation equipment, a PDA and other operation equipment. The automatic equipment comprises a stacker, an AGV, a shuttle, a commodity circulation line and a manipulator, and also comprises a three-dimensional goods shelf for storing goods. In the automatic transportation and storage process of cargoes, the overall dimension of the cargoes needs to be strictly controlled so as to avoid the problems of collision and the like of the cargoes caused by the over-limit of the overall dimension in the transportation process of the cargoes, and a Warehouse Management System (WMS) also needs to manage the overall dimension data of the cargoes, including distributing proper cargo space, distinguishing cargo conveying channels and the like according to the appearance of the cargoes, so that the overall dimension of the cargoes needs to be measured when the cargoes enter an automatic logistics system.
Currently, the wide practice of measuring the overall dimension of goods is to distinguish the length, width and height of the goods by utilizing photoelectricity; the realization mode of scheme one is through installing the frame construction of a set of cuboid shape, photoelectrically install on four stands of cuboid and two crossbeams around in the top goods direction of delivery. The photoelectric devices arranged on the upright posts are in two groups, and the length and the height of the goods are detected respectively, so that the length and the height of the goods are ensured to be within a set range; the photoelectricity from the top down that installs on the top crossbeam shines, is responsible for detecting whether the width of goods exceeds limit. When photoelectric triggering is detected, the appearance of the goods is over-limited, and the goods are not allowed to be conveyed on an automatic conveying line. The second scheme is that on the basis of the first scheme, the number of pairs of detection photoelectricity is increased, the triggered photoelectricity quantity and the triggered position are analyzed after the goods enter the detection area, and the range of the overall dimension of the current goods is divided, so that the judgment and the distinction of the overall dimension ranges of various goods are realized.
In the judging scheme of the overall dimension of the goods, the first scheme can send out a signal when the goods are out of limit, and prompt that the appearance of the goods is not compliant, but the specific overall dimension of the goods cannot be measured, so that the method is only suitable for an application scene with single overall dimension of the goods, and can realize the out-of-limit detection of the overall dimension of the goods and the measurement of the overall dimension of the goods cannot be realized; according to the scheme II, the dimension distinction can be carried out on cargoes with various fixed overall dimensions, but due to the limitation of photoelectric installation positions, the distance between two adjacent groups of photoelectricity has a minimum value (such as 5 cm), so that the minimum resolution of distinguishing the overall dimensions of the cargoes is 5cm under the scheme, and the realized function is to distinguish the appearance of the cargoes into a corresponding range according to the triggering condition of photoelectricity, so that the distribution of a cargo conveying channel and the distribution of cargo storage positions (dimension matching) are realized. Due to the installation defect, the accurate measurement of the overall dimension of the goods cannot be realized by the scheme, and the number of photoelectricity is greatly increased along with the wider classification and the wider range of the overall dimension of the goods, so that the feasibility of the scheme is linearly reduced.
In summary, the existing measuring method of the overall dimension of the goods in the warehouse is limited by the photoelectric installation position, and has larger minimum resolution during measurement, and the measurement of the overall dimension of the goods with high precision can not be realized, so that the efficiency of a warehouse management system is low.
