Description

Technical Field

[0001] The utility model relates to the technical field of cargo size measuring devices, in particular to a cargo external size measuring device. Background Art

[0002] For example, for air cargo and logistics parcels, in order to improve loading efficiency and save shipping costs, the shipper packs small packages of goods together to form a large package. Before shipping, the weight and size of the goods need to be measured in order to estimate the shipping cost.

[0003] The current method of measuring the external dimensions of goods is manual measurement, using a tape measure to measure the size of large packages.

[0004] This results in the following problems: when the size of the goods is too large, manual operation is inconvenient; for special-shaped goods, especially those with protruding corners, manual measurement cannot accurately measure the size of the goods; the measured size data of the goods needs to be manually entered into the system for storage, which is prone to errors, and the correspondence between the goods and the measured size needs to be manually confirmed.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-2 The utility model provides a technical solution, a device for measuring the outer dimensions of goods, including a conveyor line 1 for conveying goods, a door-shaped frame 2 spanning above the conveyor line 1, an outer shape detection component 3 including a support beam 31 fixed to both sides and the middle position of the top of the door-shaped frame 2 and extending along the axial direction of the conveyor line 1, a sliding seat 4 slidably connected to the support beam 31 along the axial direction, and a laser radar 5 fixed to the sliding seat 4, a rack 314 is fixed to the support beam 31 along its axial direction, a servo motor 43 is provided on the sliding seat 4, and a gear 44 meshing with the rack 314 is transmission-connected to the power output end of the servo motor 43.

[0025] When in use, the conveyor line 1 conveys the goods to be tested to the corresponding position inside the door-shaped frame 2; the servo motor 43 drives the gear 44 to rotate, and due to the meshing relationship between the gear 44 and the rack 314, the sliding seat 4 can slide back and forth along the support beam 31, so that the laser radar 5 scans from both sides and the top of the goods to be tested to obtain the three-dimensional contour and size of the goods. In addition, in order to detect the weight of the goods, a weighing device is also installed on the conveyor line 1. After obtaining the data information such as the size and weight of the goods, the data is archived accordingly so that the goods can be identified and confirmed later.

[0026] The laser radar 5 processes, stores and models the data after scanning the goods, using technologies such as a modeling method based on massive laser radar grid point cloud data (CN102306180B). Since laser scanning and its three-dimensional modeling technology and data processing and storage technology are all existing technologies, they are not described here. The laser radar 5 can be a model device such as SICK laser radar scanner LMS511-20100.

[0027] See also Figure 2 The outer part of the support beam 31 is fixed with an outer shell 32, and the outer shell 32 is provided with a strip window 321 along the axial direction corresponding to the position of the laser radar 5, and the sliding seat 4 and the rack 314 are both located in the inner cavity of the outer shell 32. The outer shell 32 plays a protective role.

[0028] See also Figure 3-4The support beam 31 includes a profile beam body 311 fixedly connected to the door-shaped frame 2, a connecting plate 312 fixed to the outer wall of the profile beam body 311, and a pair of slide rails 313 axially fixed to the connecting plate 312, a rack 314 axially fixed to the connecting plate 312, and a slider 45 slidably engaged with the slide rail 313 fixed to the sliding seat 4; the sliding seat 4 includes a back plate 41 parallel to the connecting plate 312 and a vertical plate 42 vertically fixed to the edge of the back plate 41, a servo motor 43 fixed to the vertical plate 42, and a slider 45 fixed to the back plate 41. The arrangement of the slider 45 and the slide rail 313 enables the sliding seat 4 to slide steadily and smoothly along the support beam 31.

[0029] The profile beam body 311 is made of aluminum alloy, so that the profile beam body 311 has both light weight and high strength.
