Description

Technical Field

[0001] This utility model relates to the field of sorting irregularly shaped parts in logistics, and in particular to an NC sorting trolley applied to a cross-belt sorting system. Background Technology

[0002] The cross-belt sorting system is a highly efficient and intelligent sorting equipment, mainly composed of belt conveyor carts, a package feeding system, and an information identification system. This system can efficiently handle various types of packages, including boxes, cartons, and clothing parcels, with a sorting capacity of 6,000-7,700 pieces per hour according to 2022 data. The equipment comes in two types: circular and linear. It achieves energy saving and emission reduction through low-energy circular drive technology and servo electric roller direct drive technology, while also employing a modular, quick-maintenance design to improve operational efficiency.

[0003] Cross-belt conveyors are favored by major express delivery companies due to their fast sorting speed, simple loading operation, high sorting accuracy, strong customization flexibility, short delivery cycle, and cost-effectiveness, and are now widely used in major logistics centers. Their processing range is also very wide, handling cartons, envelopes, parcels, clothing, books, audio-visual products, and more.

[0004] The sorting cart sorts packages using a belt positioned between the drive and driven wheels. The belt surface is flat, which allows for effective sorting of packages that can make planar contact with the belt, such as boxes, cartons, and bags. However, packages that make point or mechanical contact with the belt are difficult to sort effectively, such as spherical or cylindrical packages. These packages tend to tumble on the belt, making them unusable for binding and proper placement. Packages that cannot be scanned and loaded are called NC (non-standard) packages (i.e., irregularly shaped packages).

[0005] Currently, when sorting NC parts, they are usually assigned to the abnormal parts line and flow into the manual sorting area. Finally, the sorting of NC parts is completed manually. This sorting method not only increases the labor intensity of sorting personnel, but also reduces the sorting efficiency of NC parts, causing great inconvenience to the sorting of NC parts in the logistics center.

[0035] like Figures 1-5 As shown in the figure, this application provides an NC sorting trolley for use in a cross-belt sorting system, including: a trolley frame body 100, a trolley belt 200, a drive mechanism 300, a stop bar limiting structure 400, and a photoelectric reset mechanism 500.

[0036] Adjacent trolley frame bodies 100 are connected by a connecting structure to form a cross belt for sorting packages. The trolley belt 200 is used to move and transport packages to the corresponding sorting slot when the trolley frame body 100 moves to the corresponding sorting slot.

[0037] The drive mechanism 300 is used to drive the trolley belt 200 to rotate. The trolley belt 200 is mounted on the trolley frame body 100 through the drive mechanism 300 and is connected to the controller. The drive mechanism 300 can effectively drive and control the trolley belt 200.

[0038] The NC sorting trolley used in the cross-belt sorting system also includes a stop bar limiting structure 400 that can effectively prevent NC parts from rolling on the trolley belt and a photoelectric reset mechanism 500 that controls the forward and reverse rotation reset action of the trolley belt 200. The stop bar limiting structure 400 is installed on the trolley belt 200, and the photoelectric reset mechanism 500 is installed on the trolley frame body 100 and is communicatively connected to the controller.

[0039] The trolley frame body 100 includes two side plates 110. The two side plates 110 are distributed parallel to each other at intervals along the direction of the cross belt conveyor. The two ends of the lower side of the two side plates 110 are connected by connecting rods 120 respectively. The connecting rods 120 are used to effectively connect and fix the two side plates 110, which further improves the stability of the trolley frame body 100.

[0040] The drive mechanism 300 includes a drive roller 310, a driven roller 320 and a roller driver 330. The drive roller 310 is used to drive the trolley belt 200 to rotate. The drive roller 310 is rotatably disposed between two side plates 110 and located at one end of the upper side of the two side plates 110. One side of the trolley belt 200 is sleeved on the drive roller 310.

[0041] The driven roller 320 is used to drive the trolley belt 200 to rotate. The driven roller 320 is rotatably disposed between the two side plates 110 and located at the other end of the upper side of the two side plates 110. The other side of the trolley belt 200 is sleeved on the driven roller 320, and through the effective combination of the driving roller 310 and the driven roller 320, the trolley belt 200 can be driven to rotate smoothly in both forward and reverse directions.

[0042] The roller driver 330 is used to drive the active roller 310 to rotate in both directions. The roller driver 330 is set between the two side plates through the driver mounting base 331 and is connected to the controller. The roller driver 330 can effectively rotate the active roller 310 in either the forward or reverse direction.

[0043] A support plate 700 is provided between the two side plates 110 to effectively support the upper surface of the trolley belt and prevent it from being wrapped and deformed by pressure. One side of the support plate 700 is set on one of the side plates 110, and the other side of the support plate 700 is set on the other side plate. The support plate 700 can effectively support the upper surface of the trolley belt 200. Multiple weight-reducing holes are also provided on the support plate 700 to further reduce the overall weight of the support plate 700 and the production cost.

[0044] The baffle limit structure 400 includes upper baffles 410 symmetrically arranged on both sides of the upper surface of the trolley belt 200 to prevent NC parts from rolling off the upper surface of the trolley belt 200 during sorting. The cross-section of the upper baffle 410 is generally trapezoidal, which further improves the overall stability of the upper baffle.

[0045] At least one vertical strip structure 420 is provided on the upper belt surface of the trolley belt 200 and between the two upper baffles 410 to restrict the NC part from rolling laterally along the upper belt surface of the trolley belt. The vertical strip structure 420 can effectively restrict the NC part from rolling laterally on the upper belt surface of the trolley belt 200, further improving the stability of the NC part on the trolley belt.

[0046] On the upper surface of the trolley belt 200, and between the two upper baffles 410, there are a plurality of limiting protrusions 430 evenly spaced to restrict the vertical rolling of the NC part along the upper surface of the trolley belt. The limiting protrusions 430 can effectively restrict the vertical rolling of the NC part on the upper surface of the trolley belt, thereby further improving the stability of the NC part on the trolley belt.

[0047] The height of the limiting protrusion 430 is less than the height of the vertical strip structure 420, which prevents NC parts from getting stuck in the limiting protrusion 430 and being unable to be sorted. This height difference can be used to effectively sort NC parts.

[0048] The vertical bar structure 420 includes a vertical bar 421 extending along the length of the upper surface of the trolley belt 200. At the upper end of the vertical bar 421, a plurality of stress-reducing teeth 422 are provided at intervals along its length to reduce the tension during the rotation of the upper surface of the vertical bar. This structure further extends the service life of the vertical bar structure.

[0049] The photoelectric reset mechanism 500 includes a photoelectric switch 510 and a corresponding reflector 520. The photoelectric switch 510 is mounted on the driver mounting base 331 via a photoelectric mounting base 511 and is connected to the controller. The reflector 520 is mounted on the support plate 700 via a reflector mounting base 521. A clearance hole 210 is provided on the lower belt surface of the trolley belt 200 between the photoelectric switch 510 and the reflector 520.

[0050] On both sides of the trolley frame body 100, protective bellows covers 600 are symmetrically installed to prevent packages from getting stuck on the connecting structure used to connect adjacent trolley frame bodies 100. The height of the protective bellows covers 600 is the same as the height of the trolley frame body 100. This structure further improves the practicality of the NC sorting trolley.

[0051] Symmetrical lower baffles 700 are provided on both sides of the lower belt surface of the trolley belt 200 to prevent packages from being stuck in the trolley frame body 100. The lower baffles 700 can effectively prevent packages from being stuck in the trolley frame body 100, further improving the sorting efficiency of the cross belt and reducing the failure rate of the cross belt.

[0052] In summary, this utility model has a reasonable overall design, simple structure, and convenient operation. By using a stop bar limiting structure on the trolley belt to restrict the rolling of NC parts on its upper side, the NC parts can be effectively sorted via the cross belt, avoiding manual sorting. This sorting method not only reduces the labor intensity of sorting personnel but also improves the sorting efficiency of NC parts, bringing great convenience to the sorting of NC parts in logistics centers.
