[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0032] like Figures 1 to 8As shown, this embodiment provides a sorting machine, which includes a frame 10 and a sorting trolley 20. The frame 10 includes a guide rail 11, which includes an upper surface 111, a lower surface 112, and a vertical surface 113 connecting the upper surface 111 and the lower surface 112. The sorting trolley 20 is supported by the guide rail 11 and can move along the guide rail 11. The sorting trolley 20 includes a body and a wheel assembly 22 mounted on the body. The wheel assembly 22 includes an upper traveling wheel 221, a lower traveling wheel 222, and a guide wheel 223. The axes of the upper traveling wheel 221 and the lower traveling wheel 222 both extend along a first horizontal direction, and the axis of the guide wheel 223 extends along a vertical direction. The upper traveling wheel 221 is supported by the upper surface 111 and rolls with the upper surface 111, the lower traveling wheel 222 rolls with the lower surface 112, and the guide wheel 223 rolls with the vertical surface 113.

[0033] In this embodiment, as Figure 3 As shown, the guide rail 11 includes an upper surface 111 and a lower surface 112 arranged opposite to each other. The upper surface 111 supports the upper traveling wheel 221 of the wheel assembly 22, and the upper surface 111 and the upper traveling wheel 221 roll in cooperation. The lower surface 112 rolls in cooperation with the lower traveling wheel 222 of the wheel assembly 22, so that the upper traveling wheel 221 and the lower traveling wheel 222 are located on the upper and lower sides of the guide rail 11, respectively. This restricts the vertical movement of the sorting cart 20, preventing the sorting cart 20 from jumping upwards when moving along the guide rail 11. This effectively reduces the noise caused by the upward jumping of the sorting cart 20, improves the comfort of the surrounding environment, and improves the stability of the movement of the sorting cart 20. This effectively prevents the items placed on the sorting cart 20 from shifting due to vibration, thereby ensuring the accuracy and effectiveness of item sorting. Meanwhile, the guide wheel 223 of the wheel assembly 22 rolls in cooperation with the vertical surface 113 of the guide rail 11, which restricts the movement of the sorting cart 20 in the first horizontal direction, further improving the stability of the sorting cart 20 as it moves along the guide rail 11. This prevents the sorting cart 20 from shifting position, which could lead to item displacement or even falling during the sorting process, thus ensuring safety. Furthermore, as the sorting cart 20 moves along the guide rail 11, the guide rail 11 rolls in cooperation with the upper and lower traveling wheels 221 and 222 of the wheel assembly 22, improving the ease of movement of the sorting cart 20. Simultaneously, it rolls in cooperation with the guide wheel 223 to correct the sorting cart 20's deviation. Compared to tracks in related technologies, it combines the functions of both a track and a guide, resulting in a compact structure that facilitates miniaturization of the sorting machine, thereby improving its versatility and flexibility.

[0034] Optionally, in this embodiment, the lower traveling wheel 222 is spaced apart from the lower surface 112, and the preset distance between the lower traveling wheel 222 and the lower surface 112 is t. Preferably, 0.2mm≤t≤0.5mm. When the sorting cart 20 moves forward along the guide rail 11, the upper traveling wheel 221 rolls along the upper surface 111, and the lower traveling wheel 222 is spaced apart from the lower surface 112 by a preset distance t. The two do not contact each other to reduce the moving load of the sorting cart 20, which is beneficial to reduce wear and extend service life. At the same time, once the sorting cart 20 jumps upward, the contact between the lower traveling wheel 222 and the lower surface 112 will prevent the sorting cart 20 from jumping upward, ensuring that the sorting cart 20 moves smoothly.

[0035] Optionally, drop-off ports are provided on both sides of the guide rail 11, and the sorting trolley 20 moves along the guide rail 11 and is used to transport items to the drop-off ports.

[0036] Optionally, the guide rail 11 is annular. In another embodiment, the shape of the guide rail 11 can be specifically set according to the actual use scenario, and no specific limitation is made here.

[0037] Optionally, the upper traveling wheel 221, the lower traveling wheel 222, and the guide wheel 223 are all bearings. The bearings have high strength, long service life, and can be purchased directly from existing technologies with suitable specifications, resulting in low cost.

[0038] Furthermore, such as Figures 1 to 2 As shown, multiple sorting carts 20 are arranged sequentially along the extension direction of the guide rail 11. The wheel assembly 22 of each sorting cart 20 includes two upper support shafts 224 and two upper traveling wheels 221. The two upper support shafts 224 are arranged at intervals along the forward direction of the sorting cart 20, and the two upper traveling wheels 221 are rotatably connected to the two upper support shafts 224 respectively. The sorting machine also includes several chain plates 23. The two adjacent upper support shafts 224 of any two adjacent sorting carts 20 are respectively set with one chain plate 23. The two ends of each chain plate 23 are respectively sleeved on the two corresponding upper support shafts 224.

[0039] In this embodiment, as Figure 6 As shown, along the forward direction of the sorting trolley 20, the distance between the two upper traveling wheels 221 of the same sorting trolley 20 is L1. The chain plate 23 is sleeved on the two adjacent upper support shafts 224 of the two adjacent sorting trolleys 20, and the distance between the two adjacent upper support shafts 224 is L2. This arrangement allows one sorting trolley 20 to correspond to two pitches L1 and L2, which makes the polygonal effect small when the sorting trolley 20 moves along the guide rail 11. Therefore, the vibration and noise of the sorting trolley 20 when it moves along the guide rail 11 are small.

[0040] Furthermore, such as Figures 4 to 8As shown, the wheel assembly 22 also includes a support seat 24 fixedly connected to the vehicle body. Two upper support shafts 224 are inserted into the support seat 24. Each upper support shaft 224 includes a first end located on the first side of the support seat 24 and a second end located on the second side of the support seat 24. The upper traveling wheel 221 is sleeved on the first end of the upper support shaft 224, and the chain plate 23 is sleeved on the second end of the upper support shaft 224.

[0041] In this embodiment, the upper support shaft 224 is provided with an upper traveling wheel 221 and a chain plate 23 at both ends of the support base 24, so that the two ends of the upper support shaft 224 are subjected to force, thereby improving the force balance of the upper support shaft 224 and thus improving the reliability of the upper support shaft 224.

[0042] Optionally, such as Figure 7 As shown, the upper support shaft 224 includes a shoulder screw 236 and a locking nut 234. The cylindrical shoulder of the shoulder screw 236 is inserted into the hole on the support seat 24. The upper traveling wheel 221 and the chain plate 23 are both sleeved on the cylindrical shoulder and can rotate around the cylindrical shoulder. The locking nut 234 is threadedly connected to the threaded part of the shoulder screw 236 to lock the relative positions of the upper traveling wheel 221, the chain plate 23, and the support seat 24.

[0043] Optionally, such as Figure 7 As shown, the wheel assembly 22 also includes a lower support shaft 25, which is inserted into the support seat 24 and is arranged parallel to and spaced apart from the two upper support shafts 224. The lower traveling wheel 222 is rotatably sleeved with the lower support shaft 25.

[0044] Furthermore, such as Figure 8 As shown, the wheel assembly 22 also includes a lower support shaft 25 and three spacer sleeves 26. The lower support shaft 25 is connected to the support base 24 and is parallel to the two upper support shafts 224. The three spacer sleeves 26 are fitted onto the lower support shaft 25 and the two upper support shafts 224 in a one-to-one correspondence. The lower traveling wheel 222 and the two upper traveling wheels 221 are fitted onto the three spacer sleeves 26 in a one-to-one correspondence. The three spacer sleeves 26 are used to ensure that the lower traveling wheel 222 and the two upper traveling wheels 221 are all spaced apart from the support base 24 in a one-to-one correspondence.

[0045] In this embodiment, as Figure 8 As shown, the spacer sleeve 26 allows the lower traveling wheel 222 and the two upper traveling wheels 221 to be spaced apart from the support base 24, limiting the axial position of the upper traveling wheel 221 relative to the upper support shaft 224, and at the same time limiting the axial position of the lower traveling wheel 222 relative to the lower support shaft 25. This avoids friction between the lower traveling wheel 222, the two upper traveling wheels 221 and the support base 24, thereby reducing the wear of the support base 24.

[0046] Preferably, in this embodiment, as Figure 8 As shown, reinforcing spacers 231 are provided at both ends of the chain plate 23. The reinforcing spacers 231 are used to fit around the outer periphery of the upper support shaft 224, thereby improving the connection strength between the chain plate 23 and the upper support shaft 224, and reducing the wear between the chain plate 23 and the upper support shaft 224.

[0047] Preferably, in this embodiment, as Figure 8 As shown, the shoulder screw 236 passes through the upper traveling wheel 221, the support seat 24, and the chain plate 23 in sequence before extending out. A reinforcing spacer 231 is provided between the shoulder screw 236 and the chain plate 23. A sealing washer 232, a large washer 233, and a locking nut 234 are sequentially provided at the protruding end of the shoulder screw 236. The locking nut 234 can lock the shoulder screw 236 to the support seat 24, and the sealing washer 232 can protect the reinforcing spacer 231 to prevent damage to the reinforcing spacer 231. Furthermore, a roller sleeve 235 is provided on the outside of the reinforcing spacer 231 to limit the relative position of the support seat 24 and the locking nut 234 along the axial direction, ensuring the performance of the sorting cart 20.

[0048] Optionally, in this embodiment, as Figure 7 and Figure 8 As shown, the wheel assembly 22 also includes a guide wheel shaft 27, which is connected to the support base 24 and is perpendicular to the upper support shaft 224 and the lower support shaft 25. The guide wheel 223 is sleeved on the guide wheel shaft 27, and along the first horizontal direction, the outer edge of the guide wheel 223 is located between the upper traveling wheel 221, the lower traveling wheel 222 and the support base 24. In the vertical direction, the guide wheel 223 is located between the upper traveling wheel 221 and the lower traveling wheel 222, which can improve space utilization and is conducive to miniaturization design.

[0049] Furthermore, such as Figure 6 As shown, the line connecting the centers of the lower traveling wheel 222 and the two upper traveling wheels 221 forms an isosceles triangle, and the center of the lower traveling wheel 222 is located at the vertex of the isosceles triangle.

[0050] In this embodiment, when the sorting cart 20 vibrates and bounces upward, this arrangement allows the lower traveling wheel 222 to apply a force to the guide rail 11 through the lower surface 112. This force passes between the two upper traveling wheels 221 and is equidistant from the two upper traveling wheels 221. As a result, when the sorting cart 20 falls, the two upper traveling wheels 221 contact the upper surface 111 of the guide rail 11 approximately simultaneously. This effectively prevents the sorting cart 20 from tilting, making the movement of the sorting cart 20 more stable and ensuring the stability of the sorting cart 20.

[0051] Optionally, such as Figure 4As shown, the sorting trolley 20 also includes a conveying assembly 30 installed on the trolley body. When the sorting trolley 20 moves along the guide rail 11 to the sorting position, the conveying assembly 30 is used to convey items to the drop-out port on the side of the guide rail 11 to ensure the performance of the sorting machine.

[0052] Optionally, such as Figure 4 As shown, the conveying assembly 30 includes a drive roller and a driven roller 32 arranged at intervals along a first horizontal direction, and a conveyor belt 33 sleeved on the drive roller and the driven roller 32. The conveyor belt 33 is used to convey items to the side of the guide rail 11. The axes of the drive roller and the driven roller 32 both extend along a second horizontal direction. The center of the lower traveling wheel 222 corresponds to the width center of the conveyor belt 33. The two upper traveling wheels 221 are symmetrically arranged about the width center of the conveyor belt 33 to improve the balance of the supporting force on the sorting cart 20 and ensure the stability of the sorting cart 20.

[0053] Optionally, such as Figure 7 and Figure 8 As shown, the wheel assembly 22 also includes a support base 24, a lower traveling wheel 222 and two upper traveling wheels 221, all of which are mounted on the support base 24, and the center line connecting the three forms a triangle. The support base 24 has a clearance groove 241, which is located inside the triangle, and the guide wheel 223 is rotatably mounted in the clearance groove 241.

[0054] In this embodiment, as Figure 7 and Figure 8 As shown, the lower traveling wheel 222 and the two upper traveling wheels 221 are arranged in a triangular pattern on the support base 24, which allows the middle part of the support base 24 to have an obstacle groove 241. The obstacle groove 241 can provide installation space for the guide wheel 223, thereby improving space utilization and facilitating the miniaturization design of the sorting cart 20.

[0055] Furthermore, such as Figure 7 and Figure 8 As shown, the wheel assembly 22 also includes a guide wheel shaft 27, which is located in the clearance groove 241 and is inserted into the support seat 24. The guide wheel shaft 27 extends in the vertical direction, and the guide wheel 223 is rotatably sleeved with the guide wheel shaft 27.

[0056] In this embodiment, the guide wheel shaft 27 is a shoulder screw, the guide wheel 223 is sleeved on the shoulder, and the threaded part is threadedly connected to the threaded hole on the support seat 24, thereby ensuring the installation stability of the guide wheel 223 and facilitating the installation of the guide wheel 223, thus improving the ease of installation.

[0057] Furthermore, such as Figure 1 and Figure 2As shown, the sorting machine includes two guide rails 11, which are parallel to each other and spaced apart along a first horizontal direction. The vertical surfaces 113 of the two guide rails 11 are opposite each other along the first horizontal direction. Each sorting trolley 20 includes two wheel assemblies 22, which are arranged one-to-one with the two guide rails 11. The guide wheel 223 of each wheel assembly 22 is in rolling engagement with the vertical surface 113 of the corresponding guide rail 11.

[0058] In this embodiment, as Figure 1 and Figure 2 As shown, the vertical surfaces 113 of the two guide rails 11 are opposite each other along the first horizontal direction, and the guide wheels 223 of the two wheel assemblies 22 are respectively in rolling cooperation with the vertical surfaces 113 of the two guide rails 11. The vertical surfaces 113 of the two guide rails 11 act simultaneously to limit the movement of the sorting cart 20 along the first horizontal direction, so that the sorting cart 20 moves more smoothly along the guide rails 11 and there will be no positional deviation, thereby ensuring the performance of the sorting cart 20.

[0059] Furthermore, such as Figure 4 As shown, the vehicle body includes two side plates 211 that are spaced apart and parallel to each other along the forward direction of the sorting trolley 20; the sorting trolley 20 includes two wheel assemblies 22, which are spaced apart at both ends of the vehicle body along a first horizontal direction. Each wheel assembly 22 also includes a support seat 24. The upper traveling wheel 221, the lower traveling wheel 222, and the guide wheel 223 are rotatably mounted on the support seat 24. The support seat 24 is located between the two side plates 211, and the support seat 24 and the two side plates 211 are fastened together by fasteners 213. The axis of the fasteners 213 extends along a second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction.

[0060] In this embodiment, the support base 24 is located between the two side plates 211, thereby enhancing the overall structural strength of the vehicle body. The support base 24 is made of metal, and threaded holes 242 are respectively provided at both ends of the support base 24 along the second horizontal direction. Fasteners 213 pass through the through holes on the side plates 211 and are threaded into the threaded holes 242 to connect the support base 24 and the side plates 211, ensuring the reliability of the connection between the side plates 211 and the support base 24.

[0061] Optionally, in this embodiment, as Figure 7 As shown, at least two threaded holes 242 are respectively provided at both ends of the support base 24 along the second horizontal direction, and at least two through holes are provided at corresponding positions on the side plate 211. The at least two through holes and the at least two threaded holes 242 are connected in a one-to-one correspondence. At least two fasteners 213 are provided in a corresponding manner. The at least two fasteners 213, the at least two through holes and the at least two threaded holes 242 are provided in a one-to-one correspondence to improve the connection stability between the side plate 211 and the support base 24.

[0062] Optionally, in this embodiment, the support base 24 is made of cast iron or aluminum profile, and no specific limitation is made here.
