[0039] See also Figure 1-Figure 2 The tray sorting machine is equipped with a supply area 8 for loading the tray sorting trolley 3 and a sorting area 9 for the tray sorting trolley 3 to transport the items to be sorted and sort them to the set grid 91. The supply area 8 and the sorting area 9 are both arranged outside the frame 1. The supply area 8 can be loaded manually or automatically. Each sorting area 9 is equipped with a plurality of chute structures arranged in sequence along the length direction of the frame 1, and each chute structure is equipped with a grid 91. Figure 3 The track 2 is fixed to the top of the frame 1. The track 2 is preferably a ring structure that can achieve horizontal circulation, with a small footprint and strong sorting capacity. Of course, in other embodiments, the track 2 can also be a straight strip structure or a special-shaped structure.

[0040] See Figure 4 as well as Figure 5The track 2 can be specifically an aluminum profile structure or a sheet metal structure. The track 2 includes a bottom plate 21, a side plate 22, a top plate 23 and a baffle 24. The side plates 22 are configured with four pieces. The four side plates 22 are respectively arranged at intervals on the top of the bottom plate 21. The adjacent side plates 22 are enclosed to form a track groove, wherein the two pairs of side plates 22 located on the outside are enclosed to form a first track groove, and the pair of side plates 22 located in the middle are enclosed to form a second track groove. The top plates 23 are configured with two pieces. The first end of each top plate 23 is fixed to the side plate 22 located on the outside of the bottom plate 21, and the second end of each top plate 23 extends to the top of the side plate 22 located in the middle of the bottom plate 21, and the top plate 23 is opposite to the bottom plate 21.

The tray sorting trolley 3 includes a tray sorting device and a running wheel 36. Figure 4-Figure 8 The flip tray sorting device includes a base 31, a linkage component 32 and a tray 33 fixed to the linkage component 32; the tray 33 is used to carry the items to be sorted; the linkage component 32 can be rotatably installed on the base 31 to drive the tray 33 to flip left and right relative to the track 2, so that the tray 33 can switch between a first state in which it can load goods and a second state in which it can unload goods, so as to stably carry the items to be sorted and be able to sort the items to be sorted to the set grid 91; a locking component 34 is arranged on the base 31, and the linkage component 32 is provided with an arc-shaped guide groove 322, and the locking component 34 and the guide groove 322 can be slidably matched. When the locking component 34 and the first state of the guide groove 322 are locked, When the locking component 34 is engaged with the second end of the guide groove 322, the locking component 34 locks the flipped linkage component 32 and places the tray 33 in the second state, which plays a role of limiting and prevents the tray 33 from flipping over and contacting the track 2 or the frame 1, thereby affecting its normal operation on the track 2; the walking wheel 36 is arranged at the bottom of the base 31, and the walking wheel 36 is movably engaged with the track 2, so that the flip tray sorting trolley 3 can run smoothly along the extension direction of the track 2.

[0042] As a preferred embodiment, in order to enable the tray 33 to carry the items to be sorted more stably, the linkage component 32 is also provided with a locking groove 323, which is located at the first end of the guide groove 322 and is connected to the guide groove 322. The locking component 34 can switch between cooperating with the locking groove 323 and disengaging from the locking groove 323, which can reliably lock the tray 33 in the above-mentioned first state and allow the tray 33 to smoothly switch to the above-mentioned second state.

The rotation center of the lifting member 35 is perpendicular to the pivot center of the lifting member 35. In this way, the unloading device 4 lifts the linkage member 32 away from one end of the unloading port of the pallet 33, so that the lifting member 35 drives the linkage member 32 and the pallet 33 to move upward, so that the locking member 34 is separated from the locking groove 323, and the locking connection between the two is unlocked. When the linkage member 32 is lifted to make the bottom wall of the guide groove 322 on it contact with the locking member 34, the linkage member 32 rotates around its rotation center, thereby driving the pallet 33 to flip over and realize unloading. Of course, in other embodiments, the locking groove 323 can also be configured as a shallower concave structure, so that the locking member 34 and the locking groove 323 can be matched directly by using the force applied to the linkage member 32 by the unloading device 4.

In this way, the tilting tray sorting trolley 3 is driven to move on the track 2.

[0058] The tilting tray sorting device of the present invention has the following advantages:

[0059] By arranging the tray 33 on the linkage component 32, the linkage component 32 is rotatably connected to the base 31 to realize the flipping action of the tray 33. When the linkage component 32 changes its position, the swing amplitude is small, and the time required for the tray 33 to switch from the first state to the second state is short, which is conducive to improving the sorting efficiency, thereby helping to reduce the width of the grid 91.

[0060] The distance between the rotation center of the tray 33 and the linkage component 32 is short, and the throwing force on the items to be sorted is small, so that the items to be sorted can be smoothly transported to the set grid 91, and there is no phenomenon that the items to be sorted are damaged by throwing;

[0061] The locking member 34 and the guide groove 322 are arranged in cooperation with each other so that the tray 33 can stably carry the items to be sorted, and can also guide the tray 33 by slidingly cooperating with the locking member 34 and the guide groove 322 during the turning of the tray 33, so that the turning action of the tray 33 is smoother, so that the items to be sorted can be more smoothly transported to the set grid 91, and the throwing force on the items to be sorted is reduced. At the same time, the locking member 34 and the guide groove 322 are arranged in cooperation with each other so that the tray 33 can be limited, so as to prevent the tray 33 from turning over excessively and contacting with the track 2 or the frame 1, thereby affecting the normal operation.

[0062] The tilting tray sorting trolley 3 is separated from the unloading device 4, that is, no driving components are provided on the tilting tray sorting trolley 3, so that the overall structure of the tilting tray sorting trolley 3 is more compact, more convenient for assembly and layout, and the weight is greatly reduced, so that the operation on the track 2 is smoother and more stable, and the required driving force is smaller, which helps to reduce energy consumption and lower the operating cost;

[0063] The tray 33-type bearing structure is used, which can be used for normal sorting of lightly thrown, rounded and other items that are not suitable for sorting by cross-belt sorters, and has strong sorting adaptability;

[0064] It is beneficial to use a pure mechanical structure as the reset device 7 of the tilting tray sorting trolley 3, which has a simple structure, low energy consumption, and is beneficial to reducing operating costs;

[0065] The main drive adopts a common motor-driven traction chain 53, and the tilting tray sorting trolley 3 adopts a purely mechanical structure. The entire system has a low cost and great economic value.

[0066] When the main ring speed of the tilting sorting trolley 3 is 1.2m / s, the sorting efficiency can reach 8640 pieces / hour. If a double-end feeding configuration is adopted, the maximum theoretical processing efficiency can reach 17280 pieces / hour, and the sorting efficiency is high;

[0067] It is suitable for low-speed operation and is more suitable for manual feeding mode. It does not require a multi-level feeding system.
