Description

Technical Field

[0001] The present invention relates to the technical field of parcel sorting, and in particular to a sorting trolley and sorting equipment. Background Art

[0002] There are many types of item sorting equipment on the market, but there is no equipment that can be used to sort all kinds of items. Equipment that can be used to sort large-sized items is difficult to be used to sort very small-sized items. In particular, there are very few equipment that can truly adapt to the sorting of special-shaped mail.

[0003] Currently, narrow-belt sorters on the market can only unload items placed on them using a narrow belt within a limited distance. This presents the following adaptability issues: They are not suitable for sorting odd-shaped items, as they can easily cause items to tumble during unloading, leading to sorting errors or incomplete unloading. They are also not suitable for sorting items with smooth bottoms, as these can easily slip against the narrow belt surface during unloading, causing sorting errors or incomplete unloading. Summary of the Invention

[0004] The purpose of the present invention is to provide a sorting trolley and sorting equipment, which solves the problem that existing sorting machines cannot sort special-shaped objects, objects with smooth bottom surfaces, etc.

[0005] To achieve this object, the present invention adopts the following technical solutions:

[0007] A vehicle frame, wherein a traveling assembly is provided on the vehicle frame, and a conveying assembly is provided along the length direction of the vehicle frame;

[0008] A sorting block is connected to the conveyor belt of the conveying assembly. The conveyor belt moves to drive the sorting block to move along the length direction of the frame to push and transport articles.

[0009] The sorting trolley includes a frame with a traveling assembly on the frame, and the movement of the sorting trolley is achieved by the traveling assembly. The frame is provided with a conveyor belt along its length, and the sorting block is connected to the conveyor belt. The conveyor belt moves to drive the sorting block to move along the length of the frame, thereby pushing and delivering the items transported on the conveyor belt, preventing special-shaped items or items with smooth bottom surfaces from slipping between the conveyor belt, and realizing the sorting of special-shaped items and items with smooth bottom surfaces.

[0010] As a preferred embodiment of the above-mentioned sorting trolley, both ends of the sorting block along the width direction of the frame protrude from the conveyor belt and are slidably connected to the frame, and one end of the sorting block along the width direction of the frame is provided with a first connecting portion, and the other end is provided with a second connecting portion;

[0011] The first connecting portion of one sorting trolley is obliquely matched with the second connecting portion of another sorting trolley so that the two adjacent sorting trolleys are connected.

[0012] The above arrangement enables small items that fall onto the frame between two adjacent conveyor belts to be sorted.

[0013] As a preferred solution of the above-mentioned sorting trolley, the first connecting portion is a first inclined surface, and the second connecting portion is a second inclined surface that can cooperate with the first inclined surface. The first inclined surface of one sorting trolley can fit with the second inclined surface of another sorting trolley.

[0014] The first connecting portion is a first inclined surface, and the second connecting portion is a second inclined surface that matches the first inclined surface. The first inclined surface of one sorting trolley fits with the second inclined surface of another sorting trolley so that there is no gap between the sorting blocks of the two adjacent sorting trolleys to prevent objects from being jammed, so as to be suitable for sorting objects of different sizes.

[0015] As a preferred solution of the above-mentioned sorting trolley, a first sliding member is provided on the frame on both sides of the conveyor belt, and a second sliding member is provided on the bottom surface of both ends of the sorting block along the width direction of the frame, one of the first sliding member and the second sliding member is a convex portion, and the other of the first sliding member and the second sliding member is a concave portion, and the convex portion extends into the concave portion and can slide relative to the concave portion.

[0016] The sliding connection between the sorting block and the vehicle frame is achieved by the cooperation between the convex part and the concave part, and the structure is simple and easy to prepare.

[0017] As a preferred solution of the above-mentioned sorting trolley, the sorting trolley further includes:

[0018] A driving assembly is configured to drive the conveyor belt to move, so as to drive the sorting block to move.

[0019] The setting of the driving component can drive the conveyor belt to move, and then drive the sorting block to move, thereby realizing the automatic pushing of items.

[0020] As a preferred solution of the above-mentioned sorting trolley, the driving assembly is a thumbwheel assembly, the sorting block and the thumbwheel assembly are respectively located on the upper and lower sides of the conveyor belt, and divide the conveyor belt equally.

[0021] The driving component is a thumbwheel component, which can drive the conveyor belt and then drive the movement of the sorting block; the sorting block and thumbwheel component are respectively located on the upper and lower sides of the conveyor belt, and divide the conveyor belt evenly, so that when the thumbwheel component moves from one end of the frame to the other, the sorting block can move from the other end of the frame to one end.

[0022] As a preferred solution of the above-mentioned sorting trolley, the sorting trolley further includes:

[0023] A tensioning assembly is used to adjust the tension of the conveyor belt.

[0024] The setting of the tensioning component can adjust the tension of the conveyor belt to meet different needs.

[0025] As a preferred solution of the above-mentioned sorting trolley, a tensioning groove is provided on the sorting block, the notch of the tensioning groove is arranged toward the conveyor belt, one end of the tensioning assembly is movably connected to the bottom of the tensioning groove, and the other end of the tensioning assembly is connected to the conveyor belt.

[0026] The tensioning assembly can adjust the extent to which the conveyor belt extends into the tensioning groove by moving along the groove depth direction of the tensioning groove, thereby adjusting the tensioning force of the conveyor belt, and the adjustment is relatively convenient.

[0027] As a preferred solution of the above-mentioned sorting trolley, the frame is provided with a first overlapping portion at one end thereof along the width direction, and a second overlapping portion at the other end thereof along the width direction;

[0028] The first overlapping portion of one sorting trolley can overlap and cooperate with the second overlapping portion of another sorting trolley.

[0029] The cooperation between the first overlapping portion and the second overlapping portion of the two adjacent sorting trolleys prevents items from falling into the gap between the two adjacent sorting trolleys, thereby ensuring the sorting of items of different sizes and having a wide range of applications.

[0030] The present invention also provides a sorting device, comprising a track and the above-mentioned sorting trolley, wherein a plurality of the sorting trolleys are connected in sequence to form a sorting trolley group, and the sorting trolley group can move along the track.

[0031] By applying the above-mentioned sorting trolley, the sorting equipment can be adapted to the sorting of irregular-shaped objects and objects with smooth bottoms, and has high versatility and a wide range of uses.

[0032] Beneficial effects of the present invention:

[0033] The sorting trolley proposed in the present invention includes a frame, a walking assembly is provided on the frame, and walking is achieved by the walking assembly. The frame is provided with a conveyor belt along its length direction, and the sorting block is connected to the conveyor belt. The conveyor belt moves to drive the sorting block to move along the length direction of the frame, thereby pushing and delivering the items conveyed on the conveyor belt, preventing special-shaped items or items with smooth bottom surfaces from slipping between the conveyor belt, and realizing the sorting of special-shaped items and items with smooth bottom surfaces.

[0034] The sorting equipment proposed by the present invention can sort irregular-shaped objects and objects with smooth bottoms by applying the above-mentioned sorting trolley, and has strong versatility and a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] Example 1:

[0059] like Figure 1-4 As shown, this embodiment provides a sorting trolley 100 for sorting items. The sorting trolley 100 includes a frame 1 and a sorting block 3. Walking components 12 are provided at both ends of the bottom of the frame 1. The walking component 12 enables the frame 1 to move along the walking direction. A conveying component 2 is provided on the frame 1 along its length direction. The sorting block 3 is connected to the conveyor belt 21 of the conveying component 2. The conveyor belt 21 moves to drive the sorting block 3 to move along the length direction of the frame 1 (the length direction of the frame 1 is the sorting direction of items). While conveying the items through the conveyor belt 21, the sorting block 3 can push and send special-shaped items or items with smooth bottom surfaces to prevent the items from slipping on the conveyor belt 21.

[0060] Preferably, both ends of the sorting block 3 along the width direction of the frame 1 protrude from the conveyor belt 21 and are slidably connected to the frame 1. One end of the sorting block 3 along the width direction of the frame 1 is provided with a first connecting portion 31, and the other end is provided with a second connecting portion 32; the first connecting portion 31 of one sorting trolley 100 is obliquely matched with the second connecting portion 32 of another sorting trolley 100 to connect the two adjacent sorting trolleys 100, thereby realizing the sorting of items of different shapes, and also being able to sort small items that fall between the conveyor belts 21 of adjacent sorting trolleys 100. The sorting trolley 100 is suitable for sorting of all categories and has a wide range of applications.

[0061] Specifically, the two ends of the frame 1 are equipped with a walking assembly 12 through the end support plates. The walking assembly 12 includes a walking wheel 121 and a traction assembly. Multiple sorting carts 100 are connected through the traction assembly to realize the drive of the sorting carts 100. Specifically, the traction assembly includes a driving sprocket, a driven sprocket and a traction chain 122. The driving sprocket is driven by a driving device. The sorting cart 100 is connected to the traction chain. In this embodiment, the chain shaft of the traction chain is connected to the end support plate 10 of the frame 1 of the sorting cart 100 (see Figure 1-Figure 5 ) is rotatably connected, and the walking wheel 121 is rotatably set on the chain shaft of the traction chain 122 which is rotatably connected to the end support plate 10. When the driving device drives the active sprocket to rotate, the movement of the sorting trolley 100 is driven by the traction chain 122.

[0062] Alternatively, as Figure 1 As shown, the first connecting portion 31 is a first inclined surface, and the second connecting portion 32 is a second inclined surface that can cooperate with the first inclined surface. The first inclined surface of one sorting trolley 100 can fit with the second inclined surface of another sorting trolley 100, so that there is no gap between the sorting blocks 3 of the two adjacent sorting trolleys 100, preventing objects from being jammed, so as to be suitable for sorting objects of different sizes.

[0063] Optionally, a first sliding member is provided on both sides of the conveyor belt 21 on the frame 1, and a second sliding member is provided on the bottom surface of each end of the sorting block 3 along the width direction of the frame 1. One of the first sliding member and the second sliding member is a protrusion 33, and the other of the first sliding member and the second sliding member is a recessed portion 11. The protrusion 33 is slidably connected to the recessed portion 11. The cooperation between the protrusion 33 and the recessed portion 11 achieves a sliding connection between the sorting block 3 and the frame 1, which has a simple structure and is easy to manufacture. In this embodiment, the frame 1 is provided with recesses 11 on both sides of the conveyor belt 21. The recesses 11 are groove structures and extend along the length of the frame 1. The bottom surfaces of the sorting blocks 3 at both ends along the width of the frame 1 are provided with protrusions 33. The protrusions 33 are raised structures and extend into the recesses 11 on the corresponding sides to achieve a sliding connection. This allows the sorting blocks 3 to push and deliver items that fall between the conveyor belts 21 of two adjacent sorting carts 100 during movement, thereby achieving item sorting. Of course, in other embodiments, the protrusions 33 can be provided on the frame 1 and the recesses 11 can be provided on the sorting blocks 3.

[0064] Preferably, the sorting block 3 is provided with a sorting slope 34 on both sides of one end along the width direction of the frame 1. These slopes 34 enable the sorting block 3 to achieve surface contact with the items when the sorting cart 100 pushes them in different directions, rather than line contact. This increases the contact area between the sorting block 3 and the items, facilitating smooth pushing of the items. In other embodiments, the horizontal cross-section of the sorting block 3 is rectangular.

[0065] like Figure 4 and Figure 5 As shown, the conveying assembly 2 further includes rotating rollers 22 rotatably disposed at both ends of the frame 1, and the conveyor belt 21 is sleeved on the rotating rollers 22 to achieve transmission of the conveyor belt 21. It should be noted that the frame 1 is inserted into the annular conveyor belt 21, the conveyor belt 21 located above the frame 1 is the upper conveyor belt 211, and the conveyor belt 21 located below the frame 1 is the lower conveyor belt 212. The sorting block 3 is connected to the upper conveyor belt 211.

[0066] Optionally, a stop assembly (not shown) is provided above the upper conveyor belt 211, and the articles are located between the stop assembly and the sorting block 3. The stop assembly can prevent the articles from rolling down before being transported and unloaded.

[0067] Alternatively, as Figure 2 and Figure 5 As shown, the sorting cart 100 further includes a drive assembly 4, which is configured to drive the conveyor belt 21 to move the sorting block 3, thereby automatically pushing the items. In this embodiment, the drive assembly 4 is a thumbwheel assembly. The sorting block 3 and thumbwheel assembly are located on the upper and lower sides of the conveyor belt 21, respectively, and evenly divide the conveyor belt 21. This ensures that as the thumbwheel assembly moves from one end of the frame 1 to the other, the sorting block 3 can also move from the other end of the frame 1 to the other end.

[0068] Furthermore, the thumbwheel assembly includes a connecting assembly 41 and an unloading thumbwheel 43. The connecting assembly 41 is connected to the lower conveyor belt 212, and the unloading thumbwheel 43 is rotatably mounted on the connecting assembly 41. The thumbwheel assembly is simple in structure and easy to manufacture. As the sorting trolley 100 moves in its travel direction, the unloading thumbwheel 43 rolls against the track of the sorting equipment, thereby driving the conveyor belt 21.

[0069] Furthermore, the connecting assembly 41 includes a slider 411, a clamping plate 412, and an unloading lever 413. The slider 411 and clamping plate 412 are respectively positioned above and below the lower conveyor belt 212. One end of the unloading lever 413 is configured as a stepped shaft structure, which passes through the clamping plate 412, the lower conveyor belt 212, and the slider 411, thereby clamping the lower conveyor belt 212. The slider 411 slides on both ends within a slideway provided on the vehicle frame 1 to provide a guide. The unloading dial 43 is rotatably mounted on the unloading lever 413.

[0070] Preferably, if Figure 6 As shown, the sorting trolley 100 further includes a tensioning assembly 5, which is used to adjust the tension of the conveyor belt 21 to meet different needs.

[0071] Specifically, if Figure 7 As shown, the sorting block 3 is provided with a tensioning groove 35, the notch of which faces the conveyor belt 21. One end of the tensioning assembly 5 is movably connected to the bottom of the tensioning groove 35, and the other end of the tensioning assembly 5 is connected to the conveyor belt 21. The tensioning assembly 5 can adjust the extent to which the conveyor belt 21 extends into the tensioning groove 35 by moving along the depth direction of the tensioning groove 35, thereby adjusting the tension of the conveyor belt 21, which is relatively easy to adjust.

[0072] For example, the tensioning assembly 5 includes a position adjustment member 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 upper conveyor belt 211 in sequence and is then threadedly connected to the lower clamping plate 53. The upper clamping plate 52, the upper conveyor belt 211, and the lower clamping plate 53 are connected via the clamping bolt 54. It should be noted that a through hole 30 is provided at the bottom of the tensioning groove 35 at a position corresponding to the clamping bolt 54 (see FIG. Figure 1 ), the clamping bolt 54 can be adjusted from the outside of the sorting block 3 through the through-hole 30, preventing the clamping bolt 54 from loosening after prolonged use. The position adjustment component includes a tensioning bolt 51. One end of the tensioning bolt 51 passes through the through-hole structure at the bottom of the tensioning slot 35. The other end of the tensioning bolt 51 passes through the upper clamping plate 52 and the upper conveyor belt 211, and then is threadedly connected to the lower clamping plate 53. The upper clamping plate 52 of the tensioning assembly 5 is restrained within the tensioning slot 35. When the tensioning bolt 51 is tightened, the upper and lower clamping plates 52 and 53 do not rotate with the rotation of the tensioning bolt 51. When the tensioning force of the conveyor belt 21 needs to be adjusted, the tensioning bolt 51 is tightened to adjust the depth of the tensioning bolt 51 through the lower clamping plate 53, thereby loosening or tightening the conveyor belt 21.

[0073] Optionally, the tensioning assembly 5 can be set as a group. When the tensioning assembly 5 is set as a group, the upper clamp 52 extends along the width direction of the conveyor belt 21. At this time, multiple tensioning bolts 51 can be set, and the multiple tensioning bolts 51 are arranged at intervals along the width direction of the conveyor belt 21 to avoid inconsistent tensioning force of the conveyor belt 21 in the width direction.

[0074] In other embodiments, at least two sets of tensioning assemblies 5 may be provided. Multiple sets of tensioning assemblies 5 can prevent inconsistent tensioning forces across the width of the conveyor belt 21. In this embodiment, two sets of tensioning assemblies 5 are provided, spaced apart along the width of the conveyor belt 21. Of course, the number of sets of tensioning assemblies 5 is not limited to two, and may also be three or more. The specific number of sets of tensioning assemblies 5 can be determined based on actual needs.

[0075] Alternatively, as Figure 8 and Figure 9 As shown, a first overlapping portion 13 is provided at one end of the frame 1 along its width direction, and a second overlapping portion 14 is provided at the other end of the frame 1 along its width direction; the first overlapping portion 13 of one sorting trolley 100 can overlap and cooperate with the second overlapping portion 14 of another sorting trolley 100 to prevent items from falling into the gap between two adjacent sorting trolleys 100, thereby ensuring the sorting of items of different sizes and having a wide range of uses.

[0076] Specifically, the first overlapping portion 13 is plate-shaped and extends out of the vehicle frame 1 , and the second overlapping portion 14 is step-shaped. The first overlapping portion 13 of one sorting trolley 100 can be stacked on the second overlapping portion 14 of another sorting trolley 100 .

[0077] like Figure 10-12 As shown, this embodiment also provides a sorting device comprising a track and the aforementioned sorting trolley 100. Multiple sorting trolleys 100 are sequentially connected to form a sorting vehicle assembly, which is capable of moving along the track. By utilizing the aforementioned sorting trolleys 100, the sorting device is capable of sorting items of varying sizes and items with smooth bottoms, and has high versatility and a wide range of applications.

[0078] Specifically, the track includes a running track (not shown in the figure) and an unloading track 200. When the sorting vehicle group runs to the unloading track 200, the unloading track 200 can cooperate with the dial wheel assembly on the sorting trolley 100 and provide sorting power for the sorting block 3, so that the sorting block 3 slides along the sorting direction and pushes the items on the conveyor belt 21 out of the sorting trolley 100.

[0079] Optionally, the unloading track 200 includes a mounting seat 201, a fork 202, a sorting channel 203 and a transition channel 204. The four sorting channels 203 are fixed in an X shape on the mounting seat 201 through a transition channel 204. The two sorting channels 203 located at the front end of the walking direction are both provided with a rotatable and adjustable fork 202.

[0080] When items need to be sorted, the fork 202 rotates and connects to the sorting path 203. Specifically, the unloading thumbwheel 43 of the thumbwheel assembly can slide relative to the frame 1 under the guidance of the fork 202 and the sorting path 203, thereby pushing the items on the conveyor belt 21 out of the frame 1 to complete the item sorting.

[0081] When there is no need to sort items, the branch path 202 keeps moving straight and does not connect with the sorting path 203 , and the unloading thumbwheel 43 moves along the branch path 202 and remains stationary relative to the vehicle frame 1 .

[0082] Alternatively, the sorting vehicle assembly can be in a closed ring configuration, with the sorting vehicles 100 connected end to end to form a sorting vehicle loop. The sorting vehicles 100 run along the loop track, carrying items on the conveyor belt 21. When the sorting vehicles 100 reach a designated location, the fork 202 is activated, and the sorting block 3 moves sideways to sort and unload the items. In other embodiments, the sorting vehicle assembly can also be in an open arc or straight line configuration. The specific design can be based on actual sorting needs and will not be further illustrated here.

[0083] Example 2:

[0084] This embodiment provides a sorting cart. This embodiment differs from the first embodiment in that, whereas in the first embodiment, a thumbwheel assembly is used to drive the conveyor belt, the thumbwheel assembly's unloading thumbwheel can slide relative to the vehicle frame under the guidance of the branch and sorting lanes, thereby pushing items on the conveyor belt off the vehicle frame and completing the item sorting. In this embodiment, however, a rotating roller can be connected to a drive component, which drives the rotating roller to rotate, thereby enabling the conveyor belt to drive the sorting block to move, thereby achieving item sorting. Alternatively, the rotating roller can be a motorized roller.

[0085] It should be noted that if the rotating roller is driven by a driving device or adopts an electric roller method, there is no need to set a thumbwheel assembly.

[0086] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
