Therefore, these or other orientation terms should not be interpreted as restrictive terms.

[0033] The present application will be further explained in conjunction with the embodiments as follows:

[0034] Embodiment:

[0035] A fall-preventing tray for a cross-belt sorting machine, with reference to Figure 1 and Figure 2The tray body 1 is provided with a baffle 3 on both sides of the sorting belt 2, the height of the baffle 3 is higher than the surface of the sorting belt 2, so as to prevent the goods from rolling in the movement direction of the sorting machine, the baffle 3 is an elastic baffle 3 integrally formed of polyurethane material, two baffles 3 are respectively arranged on both sides of the sorting belt 2 to form a symmetrical structure guiding the goods, and the elastic material such as polyurethane is used as the baffle 3 because in some special cases, the operator needs to manually load and unload the goods, at this time, if the operator collides with the baffle 3, the elasticity of the polyurethane material can avoid injury.

[0036] Referring to Figure 3 , a zero return detection hole 24 is formed in the bottom of the sorting belt 2, and a mirror light sensor 61 is fixedly installed on the tray body 1, the light signal emitting end and the receiving end of the mirror light sensor 61 are directed to the bottom of the sorting belt 2, a reflecting plate 62 is fixedly arranged in the sorting belt 2, the reflecting plate 62 is used to reflect the electric signal emitted by the mirror light sensor 61, the sorting belt 2 is driven to rotate by an electric roller 4, the electric roller 4 is electrically connected with a driving card 7 through a wire, the driving card 7 is fixedly installed on the tray body 1, and the driving card 7 is in signal communication with the mirror light sensor 61; further in this embodiment, the light signal emitting direction of the mirror light sensor 61 is inclined to the side where the reflecting plate 62 is located, the inclination angle is controlled between 30°-60°, and the inclination angle is preferably 45°, the inclination direction of the plate surface of the reflecting plate 62 corresponds to the emitting direction, so that the emitted light signal is reflected along the original path to the receiving end of the mirror light sensor 61 after being reflected by the reflecting plate, specifically, the mirror light sensor 61 is installed on the driving card 7 or the tray body 1 through an acute metal sheet, and the reflecting plate 62 arranged in the sorting belt 2 is also installed in place through an installation iron sheet, and the two need to be arranged to ensure that the light signal reflected by the reflecting plate 62 can return along the original path.

[0037] Please refer to Figure 4 , in which A1 is the front view of the design, B1 is the top view of the design, the surface of the sorting belt 2 is integrally formed with two main baffle edges 21, the main baffle edges 21 extend perpendicular to the movement direction of the sorting belt 2, and are symmetrically distributed on the left and right side edges of the sorting belt 2, so as to form a constraint structure for the goods. As a preferred design, refer to Figure 5In the figure, A2 is the front view of this design, and B2 is the top view of this design. Based on the previous design, two secondary guardrails 22 are integrally formed on the surface of the sorting belt 2. The secondary guardrails 22 are spaced apart between the two main guardrails 21 and extend parallel to the main guardrails 21. The top height of the secondary guardrails 22 is lower than the top height of the main guardrails 21. By using the height difference between the main and secondary guardrails 22 to form basic protection, small rolling goods can be confined to the middle of the belt, while large goods can be pressed against the two lower guardrails, thereby improving sorting accuracy. In another embodiment of this utility model, a third design is adopted, referring to... Figure 6 In the figure, A3 is the front view of this design and B3 is the top view of this design. The sorting belt 2 is also integrally formed with several strip-shaped protrusions 23 at intervals. The strip-shaped protrusions 23 extend along the movement direction of the sorting belt 2. By setting the strip-shaped protrusions 23 perpendicular to the main guard edge 21, the rolling of the goods in the movement direction of the sorting machine can be effectively restricted.

[0038] In this embodiment, the pallet body 1 is also provided with a driven roller 5, and the driven roller 5 is also provided with a belt tensioning mechanism 51 for tensioning the sorting belt 2. The belt tensioning mechanism 51 is used to adjust the tension of the sorting belt 2 to prevent the sorting belt 2 from slipping when rotating.

[0039] In actual operation, when the sorting machine starts, the sorting belt 2 automatically performs zero-return calibration: the electric roller 4 drives the sorting belt 2 to rotate until the reflective photoelectric sensor 61 continuously detects the reflection of the light signal passing through the zero-return detection hole 24. At this time, the direction of the main guard 21 and the secondary guard 22 (or strip-shaped protrusions 23) on the surface of the sorting belt 2 is automatically aligned with the sorting area and kept in an upward state. After the goods are sorted, the electric roller 4 immediately rotates in the opposite direction, and the sorting belt 2 carries the zero-return detection hole 24 to quickly reset to the initial position where the reflective photoelectric sensor 61 captures the zero position signal, ensuring that the next round of goods loading can be performed instantly every time the pallet arrives at the feeding station.

[0040] Specifically, the sorting belt 2 in this application consists of a first sorting belt 2a and a second sorting belt 2b arranged symmetrically. The first sorting belt 2a and the second sorting belt 2b are arranged in parallel and spaced apart, and are driven by independent first electric rollers 4a and second electric rollers 4b, respectively. The first electric rollers 4a and the second electric rollers 4b are electrically connected to the corresponding drive cards 7. The drive cards 7 interact with the mirror photoelectric sensors 61 below the corresponding sorting belts 2. The dual belts are independently speed-regulated, so that the sorting efficiency of the sorting machine can be doubled at the same speed.

[0041] A sorting machine, as shown in the reference Figure 7 and Figure 8It includes a conveying track and multiple trolleys 8 set on the conveying track. Each trolley 8 is equipped with an anti-drop pallet as described in the above embodiment. In addition, a bellows cover 9 is fixedly connected to the pallet body 1 between two adjacent trolleys 8 to prevent goods from falling between the two pallets.

[0042] This embodiment targets a large number of irregularly shaped and specially sized NC parts that have emerged under the highly developed online shopping environment, such as spheres, ellipses, and polygonal shapes. This embodiment can get rid of the strict requirements of traditional sorting mechanisms on the shape of packages, and enable NC parts to operate smoothly even at linear speeds of up to 1.5 m / s. Of course, this embodiment has the same transportation capacity for ordinary goods as for NC parts.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0044] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
