[0052] The technical solutions of the present application are further illustrated below in conjunction with the accompanying drawings and through specific embodiments.

[0053] Embodiment one

[0054] As Figure 1As shown, the plurality of sorting trolleys are sequentially connected end to end to form a sorting trolley group, which is generally arranged in a loop type, each sorting trolley moves along the loop and completes the sorting operation of the articles in the moving process. Specifically, the sorting trolley is a narrow-belt sorting trolley, and a sorting block is installed on the narrow belt. The articles are placed on the narrow belt (conveying belt), and when the sorting trolley runs to the specified position along the loop track, the conveying belt rotates to unload the articles. At the same time, the sorting block can play the role of auxiliary pushing to avoid the articles slipping on the conveying belt and causing the articles to be unloaded abnormally.

[0055] As shown in the figure, Figure 1 the upper layer of the loop is defined as the sorting outward journey, and the lower layer is defined as the sorting return journey, Figure 1 the clockwise direction of the loop is the walking direction of the sorting trolley. When the sorting trolley passes through the upper layer, the articles can be unloaded. Then the sorting trolley passes through the sorting return journey empty, so that the sorting trolley can only realize single-layer sorting, and the sorting efficiency is low.

[0056] To solve the above problems, as shown in the figure, Figures 2-3 the embodiment provides a sorting trolley 100, which comprises a trolley frame 1 and two sorting blocks 3. The trolley frame 1 is provided with a walking assembly 12 and a conveying assembly 2, and the conveying assembly 2 comprises a conveying belt 21 which is arranged on the trolley frame 1 along the sorting direction (the length direction of the trolley frame 1 is the sorting direction of the articles). The two sorting blocks 3 are arranged on the conveying belt 21 on the upper and lower sides of the trolley frame 1 respectively, and divide the conveying belt 21 equally. When the sorting trolley 100 travels to the sorting outward journey and the sorting return journey through the walking assembly 12, the conveying belt 21 and the sorting block 3 facing upward can move along the sorting direction to push and send the articles on the conveying belt 21.

[0057] The bottom of the trolley frame 1 of the embodiment is provided with the walking assembly 12 at both ends along the sorting direction, so that the trolley frame 1 can move back and forth between the sorting outward journey and the sorting return journey along the walking direction through the walking assembly 12.

[0058] Specifically, the trolley frame 1 is provided with the walking assembly 12 at both ends through the end support plate 10, and the walking assembly 12 comprises a walking wheel 121 and a traction assembly. A plurality of sorting trolleys 100 are connected through the traction assembly and drive the sorting trolleys 100. Specifically, the traction assembly comprises a driving sprocket, a driven sprocket and a traction chain 122, the driving sprocket is driven by a driving device, and the sorting trolley 100 is connected with the traction chain 122. In the embodiment, the chain shaft of the traction chain 122 is rotationally connected with the end support plate 10 (see Figure 2 and Figure 3 ) of the trolley frame 1 of the sorting trolley 100, and the walking wheel 121 is rotationally arranged on the chain shaft where the traction chain 122 is rotationally connected with the end support plate 10. When the driving device drives the driving sprocket to rotate, the movement of the sorting trolley 100 is driven through the traction chain 122.

[0059] The process of unloading the goods by the single sorting trolley 100 is as follows: when the sorting trolley 100 reaches the predetermined unloading position, the conveying belt 21 moves to drive the sorting block 3 to move along the length direction of the trolley frame 1, and the sorting block 3 pushes and sends the special-shaped goods or the goods with smooth bottom surface while unloading the goods by the conveying belt 21, so as to prevent the goods from slipping on the conveying belt 21.

[0060] As shown in Figure 2 and Figure 3 , the two sorting blocks 3 are centrally symmetrically distributed on the trolley frame 1. The trolley frame 1 has a first end and a second end along the sorting direction, one of the two sorting blocks 3 is fixedly connected to the conveying belt 21 on the upper side of the first end of the trolley frame 1, and the other sorting block 3 is fixedly connected to the conveying belt 21 on the lower side of the second end of the trolley frame 1.

[0061] When the sorting trolley 100 travels to the sorting outbound, the conveying belt 21 on the upper side of the sorting trolley 100 and the sorting block 3 thereon can carry the goods, and after reaching the designated unloading position, the conveying belt 21 on the upper side of the trolley frame 1 rotates and drives the upper sorting block 3 to move along the sorting direction from the first end to the second end of the trolley frame 1 to unload the goods. At this time, the conveying belt 21 on the lower side of the trolley frame 1 rotates synchronously and drives the lower sorting block 3 to move from the second end to the first end of the trolley frame 1. When the sorting trolley 100 travels to the sorting return, the sorting trolley 100 is turned over by 180°, at this time, the conveying belt 21 on the lower side of the sorting trolley 100 and the sorting block 3 thereon are all directed upward to carry and sort the goods. By arranging two centrally symmetric sorting blocks 3 on the sorting trolley 100, double-layer sorting can be realized in the sorting outbound and the sorting return of the sorting trolley 100, and the sorting efficiency is improved. Double-layer sorting improves the utilization rate of the sorting trolley 100, and the sorting efficiency is doubled.

[0062] In order to ensure the stable sliding of the sorting block 3 along the sorting direction, the sorting block 3 protrudes from the conveying belt 21 at both ends along the width direction of the trolley frame 1, and is slidably connected with the upper end or the lower end of the corresponding trolley frame 1. The sorting block 3 on the upper side of the trolley frame 1 can be slidably fitted with the upper end surface of the trolley frame 1, and the sorting block 3 on the lower side of the trolley frame 1 can be slidably fitted with the lower end surface of the trolley frame 1, so that the sorting block 3 for sorting the goods can always be reliably fitted with the end surface of the corresponding trolley frame 1 during the double-layer sorting process of the sorting outbound and the sorting return of the sorting trolley 100, which is beneficial to improve the sorting accuracy and the sorting efficiency of the goods.

[0063] Specifically, as shown in Figures 4-6As shown, the upper end and the lower end of the frame 1 are provided with first sliding members on one side or both sides of the conveying belt 21, and the end faces of the two sorting blocks 3 are correspondingly provided with second sliding members, the number of the first sliding members is the same as that of the second sliding members, and the first sliding members and the second sliding members are one-to-one sliding fit. One of the first sliding member and the second sliding member is a convex portion 11, and the other is a concave portion 31, the convex portion 11 extends into the concave portion 31 and can slide relative to the concave portion 31.

[0064] Through the cooperation of the convex portion 11 and the concave portion 31, the two sorting blocks 3 are respectively connected with the end faces of the frame 1 in a sliding manner, which is simple in structure and easy to manufacture. In the embodiment, the upper end and the lower end of the frame 1 are provided with convex portions 11 on both sides of the conveying belt 21, the convex portions 11 are protruding structures, the convex portions 11 extend along the length direction of the frame 1, and the bottom surfaces of the two ends of the sorting block 3 in the width direction of the frame 1 are provided with concave portions 31, the concave portions 31 are groove structures, the convex portion 11 extends into the corresponding concave portion 31 to realize sliding connection. Of course, in other embodiments, the concave portion 31 can be arranged on the frame 1, and the convex portion 11 can be arranged on the sorting block 3.

[0065] As shown in Figure 4 , the sorting block 3 is provided with a sorting inclined surface 32 at both ends in the sorting direction. Through the sorting inclined surface 32, when the sorting trolley 100 pushes the articles in different directions, the sorting block 3 and the articles realize face contact pushing instead of line contact pushing, which increases the contact area of the sorting block 3 and the articles, so as to realize the smooth pushing of the articles. In other embodiments, the horizontal cross section of the sorting block 3 can also be rectangular.

[0066] As shown in Figure 5 and Figure 6 , the upper end and the lower end of the frame 1 are provided with first lap joints 13 on one side in the width direction thereof, and the upper end and the lower end of the frame 1 are provided with second lap joints 14 on the other side in the width direction thereof. The first lap joint 13 of the upper end of one sorting trolley 100 can be lap jointed with the second lap joint 14 of the upper end of the other sorting trolley 100. The first lap joint 13 of the lower end of one sorting trolley 100 can be lap jointed with the second lap joint 14 of the lower end of the other sorting trolley 100. The first lap joint 13 and the corresponding second lap joint 14 are lap jointed without contact, so that the two adjacent sorting trolleys 100 can be seamlessly connected at the upper end and the lower end, preventing the articles from falling into the gap between the two adjacent sorting trolleys 100, so as to ensure the sorting of articles of different sizes, and the use range is wide.

[0067] Specifically, the first lap joint 13 is plate-shaped and extends out of the frame 1, and the second lap joint 14 is step-shaped, and the first lap joint 13 of one sorting trolley 100 can be stacked above the second lap joint 14 of the other sorting trolley 100.

[0068] It should be noted that the sorting blocks 3 at the upper end or the lower end of the two adjacent sorting trolleys 100 protrude from the conveying belts 21 in the width direction of the frame 1 and are in sliding connection with the frame 1. The sorting blocks 3 are provided with a first connecting portion at one end in the width direction of the frame 1 and a second connecting portion at the other end. The first connecting portion at the upper end of one sorting trolley 100 is connected to the second connecting portion at the upper end of the other sorting trolley 100, and the first connecting portion at the lower end of one sorting trolley 100 is connected to the second connecting portion at the lower end of the other sorting trolley 100, so that the two adjacent sorting trolleys 100 are connected at the upper end and the lower end, thereby achieving double-layer sorting of different shapes of articles, and small articles falling between the conveying belts 21 of the adjacent sorting trolleys 100 can also be sorted, so that the sorting trolley 100 can be applied to sorting of all kinds of articles, with a wide range of applications.

[0069] Optionally, as shown in Figure 5 and Figure 6 , the first connecting portion is a first inclined surface, the second connecting portion is a second inclined surface capable of being connected to the first inclined surface, and the first inclined surface of one sorting trolley 100 is capable of being connected to the second inclined surface of the other sorting trolley 100, so that the sorting blocks 3 of the two adjacent sorting trolleys 100 are connected without gaps or with small gaps, preventing jamming of articles, and being suitable for sorting of articles of different sizes.

[0070] As shown in FIG. 7, the conveying assembly 2 further comprises rotating rollers 22 rotatably arranged at both ends of the frame 1, and two rotating rollers 22 are arranged on the end support plates 10 at the first end and the second end of the frame 1, respectively, and the four rotating rollers 22 are arranged in a rectangular shape on the frame 1,

[0071] The conveying belts 21 are sleeved on the four rotating rollers 22 to realize transmission of the conveying belts 21. It should be noted that the frame 1 is arranged in the annular conveying belts 21, the conveying belts 21 above the frame 1 are upper conveying belts, and the conveying belts 21 below the frame 1 are lower conveying belts, and the two sorting blocks 3 are connected to the upper conveying belts and the lower conveying belts, respectively.

[0072] Optionally, the upper conveying belts and the lower conveying belts are provided with stop assemblies (not shown in the figure), and the articles to be sorted are located between the corresponding stop assemblies and the sorting blocks 3 during sorting and returning, so that the articles can be prevented from rolling off before being transmitted to the unloading device.

[0073] As shown in Figure 7 , the sorting trolley 100 further comprises a driving assembly 4 configured to drive the conveying belts 21 to move, so as to drive the two sorting blocks 3 to move towards each other, so that the sorting blocks 3 facing upwards can push and send the articles, thereby achieving unloading.

[0074] In this embodiment, the drive component 4 is a dial assembly, which includes a connecting component 41 and an unloading dial 42. Two sorting blocks 3 are respectively connected to the conveyor belt 21 located on the upper side of the frame 1 and the conveyor belt 21 located on the lower side of the frame 1 via corresponding connecting components 41. The unloading dial 42 is rotatably mounted on the connecting component 41 and positioned above the corresponding sorting block 3. The unloading dial 42 can cooperate with the unloading track 200 of the sorting equipment to drive the corresponding sorting block 3 to slide along the sorting direction. The above-mentioned dial assembly has a simple structure and is easy to manufacture. During the sorting outward and return journeys of the sorting trolley 100, the unloading dial 42 will roll in contact with the track of the sorting equipment, thereby driving the conveyor belt 21 to rotate.

[0075] It should be noted that since the sorting blocks 3 on the upper and lower sides of the sorting cart 100 are the same as the drive components 4, only their distribution positions are different, for ease of description, we will take one of the sorting blocks 3 and drive components 4 as an example for explanation.

[0076] Specifically, the connecting assembly 41 includes a slider 411, a clamping plate, and an unloading lever 412. The conveyor belts 21 on the upper and lower sides of the frame 1 are respectively clamped between the corresponding sliders 411 and clamping plates. One end of the unloading lever 42 is threadedly connected to the slider 411, and the other end passes through the corresponding sorting block 3. The unloading lever 42 is rotatably mounted on the unloading lever 412. Specifically, one end of the unloading lever 412 is configured as a stepped shaft structure, which passes through the clamping plate and the conveyor belt 21 in sequence and connects to the slider 411, thereby clamping the conveyor belt 21. The two ends of the slider 411 are slidably disposed in the slide rails provided on the frame 1 to serve as guides.

[0077] like Figure 8 As shown, the sorting trolley 100 also includes a tensioning assembly, which is used to adjust the tension of the conveyor belt 21 to meet different needs.

[0078] Specifically, the sorting block 3 is provided with a tension groove 33, the opening of which faces the conveyor belt 21. One end of the tensioning component is movably connected to the bottom of the tension groove 33, and the other end is connected to the conveyor belt 21. By moving along the depth direction of the tension groove 33, the tensioning component can adjust the degree to which the conveyor belt 21 extends into the tension groove 33, thereby adjusting the tension of the conveyor belt 21, which is relatively convenient.

[0079] like Figure 8 As shown, the tensioning assembly includes a position adjustment component and a clamping assembly. The clamping assembly includes an upper clamping plate 52, a lower clamping plate 53, and a clamping bolt 54. The clamping bolt 54 passes through the upper clamping plate 52 and the conveyor belt 21 on the upper side of the frame 1 in sequence, and is then threadedly connected to the lower clamping plate 53, so as to connect the upper clamping plate 52, the conveyor belt 21 on the upper side of the frame 1, and the lower clamping plate 53 through the clamping bolt 54.

[0080] It should be noted that the bottom of the tensioning groove 33 is provided with a through hole 30 (see Figure 4 ), which can be adjusted outside the sorting block 3 to avoid loosening of the clamping bolt 54 after long-term use.

[0081] The position adjusting member of the embodiment includes a tensioning bolt 51, one end of which passes through the through hole 30 structure on the bottom of the tensioning groove 33, and the other end of which passes through the upper clamping plate 52 and the conveying belt 21 on the upper side of the vehicle frame 1 in turn and is threadedly connected with the lower clamping plate 53. The upper clamping plate 52 of the tensioning assembly is limited in the tensioning groove 33, and when the tensioning bolt 51 is screwed, the upper clamping plate 52 and the lower clamping plate 53 do not rotate with the rotation of the tensioning bolt 51. When it is necessary to adjust the tensioning force of the conveying belt 21, the tensioning bolt 51 is screwed to adjust the depth of the tensioning bolt 51 passing through the lower clamping plate 53, thereby loosening or tightening the conveying belt 21. It can be understood that the sorting block 3 on the lower side of the vehicle frame 1 is also provided with a tensioning assembly of the same structure, which will not be described here.

[0082] Alternatively, the tensioning assembly can be provided in one group, and when the tensioning assembly is provided in one group, the upper clamping plate 52 extends in the width direction of the conveying belt 21. At this time, a plurality of tensioning bolts 51 can be provided, and the plurality of tensioning bolts 51 are arranged in the width direction of the conveying belt 21 to avoid the phenomenon that the tensioning force of the conveying belt 21 is inconsistent in the width direction.

[0083] In other embodiments, at least two groups of tensioning assemblies can also be provided, and the plurality of groups of tensioning assemblies can avoid the phenomenon that the tensioning force of the conveying belt 21 is inconsistent in the width direction. In the embodiment, two groups of tensioning assemblies are provided, and the two groups of tensioning assemblies are arranged in the width direction of the conveying belt 21. Of course, the number of groups of tensioning assemblies is not limited to two groups, and can also be three groups or more groups, and the number of groups of tensioning assemblies can be set according to requirements.

[0084] As shown in Figure 9 and Figure 10 , the embodiment also provides a sorting device, which includes a track and the above-mentioned sorting trolley 100, a plurality of sorting trolleys 100 are connected in sequence to form a sorting trolley group, and the sorting trolley group can move along the track. The sorting device can not only adapt to the sorting of different sizes of articles and articles with smooth bottoms by applying the above-mentioned sorting trolley 100, but also has strong universality and wide application range. At the same time, double-layer sorting can be realized in the sorting outward journey and the sorting return journey, thereby improving the sorting efficiency of the sorting device.

[0085] Specifically, the track includes a walking track (not shown in the figure) and an unloading track 200, the unloading track 200 has two, two unloading tracks 200 are respectively installed on the lower end face of the upper layer of the ring line and the lower end face of the lower layer of the ring line. When the sorting car group runs to the unloading track 200 of the upper layer of the ring line, the unloading track 200 can cooperate with the wheel assembly on the sorting trolley 100, and provide sorting power for the sorting block 3, make the sorting block 3 slide along the sorting direction, and push the goods on the conveying belt 21 out of the sorting trolley 100. Similarly, when the sorting car group runs to the unloading track 200 of the lower layer of the ring line, the unloading track 200 can cooperate with the wheel assembly on the sorting trolley 100.
