[0002] The working principle of the existing reciprocating sorting machine is as follows: after the object is automatically scanned, it is transported to the sorting cart via the conveyor line. The sorting cart transports the object to the designated grid for delivery, and then returns to the origin to receive the next object, and the operation is repeated in this cycle.

[0003] Due to mechanical structural limitations, the movement range of each sorting trolley is limited and cannot be extended infinitely.

[0079] The specific embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings. These embodiments are only used to illustrate the present invention, but not to limit the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0082] Furthermore, in the description of the present invention, unless otherwise specified, “plurality” or “plurality of groups” means two or more.

[0083] Figure 1 FIG. 1 is a top view of a first embodiment of a sorting system. In the following description, Figure 1 The attached figure in the figure is used as a reference for the direction. Figure 1 In the figure, the length direction of the translation track 1 is defined as the left-right direction, and the sorting mechanism 4 is located on the right side of the package supply mechanism 3; the width direction of the translation track 1 is defined as the front-back direction, and the sorting lifting unit 8 is located on the front side of the translation track 1; the height direction of the frame 2 is defined as the up-down direction, wherein the direction perpendicular to the view paper and outward is the upward direction.

[0084] like Figure 1-3 As shown, the present invention provides a sorting system, which includes a translation track 1 and a package supply mechanism 3 and a plurality of sorting mechanisms 4 arranged along the extension direction of the translation track 1 .

[0085] The package supply mechanism 3 includes a package supply platform 31 and a package supply assembly. The package supply assembly includes a package supply trolley 33 and a package supply transmission unit 34 for driving the package supply trolley 33 to move along the translation track 1; the package supply platform 31 is used to convey objects to the package supply trolley 33.

[0086] The sorting mechanism 4 includes a sorting component, and the sorting component includes a sorting trolley 5, a sorting transmission unit 9, a transfer unit 6 and a material receiving unit 7. Among them, the sorting trolley 5 moves along the translation track 1 driven by the sorting transmission unit 9; the transfer unit 6 and the material receiving unit 7 are arranged in sequence along the extension direction of the translation track 1. The material receiving unit 7 includes a row of blanking chutes and a row of material receiving frames arranged in sequence from the inside to the outside along the width direction of the translation track 1. The specific number of blanking chutes included in each row of blanking chutes and the specific number of material receiving frames included in each row of material receiving frames can be set as needed. Preferably, along the horizontal width direction of the translation track 1, a row of blanking chutes and a row of material receiving frames are provided on both sides of the translation track 1.

[0087] The package supply trolley 33 can reciprocate along the translation track 1 between the package supply platform 31 and the transfer unit 6 of the sorting mechanism 4 adjacent to the package supply mechanism 3; the sorting trolley 5 can reciprocate along the translation track 1 between the transfer units 6 of two adjacent sorting mechanisms 4, or between the transfer unit 6 and the receiving unit 7 of the same sorting mechanism 4. The package supply trolley 33, the sorting trolley 5 and the transfer unit 6 all include a conveyor belt that can be transported along the horizontal width direction of the translation track 1, and the conveyor belt is used to transport objects.

[0088] During operation, the package supply trolley 33 can transport the objects received from the package supply platform 31 to the adjacent transfer unit 6, and then the sorting trolley 5 in one or more sorting mechanisms 4 will work to transport the objects to the corresponding material drop chute through direct or relay transmission, and then the conveyor belt of the sorting trolley 5 will move to make the objects enter the corresponding material drop chute, and the objects will slide down along the material drop chute and enter the receiving frame, completing the delivery of an object.

[0089] As can be seen from the above, the present invention can adjust the number of sorting mechanisms 4 according to the preset sorting volume, thereby increasing the number of material receiving units 7 to achieve capacity expansion. At the same time, the objects provided by the packaging mechanism 3 can be relayed by the sorting carts 5 of multiple sorting mechanisms 4 and delivered to the material receiving unit 7 far away from the packaging mechanism 3, breaking through the limitation of the single sorting transmission unit 9 on the moving range of the sorting cart 5, and meeting the capacity expansion demand.

[0090] Figure 1 The first embodiment of the sorting system of the present invention is shown, wherein the translation track 1 is in a straight line shape, and a plurality of sorting mechanisms 4 are arranged on one side of the package supply mechanism 3 along the extension direction of the translation track 1. Figure 1 The working principle of the sorting system of the present invention is specifically described:

[0091] Embodiment 1 includes three sorting mechanisms 4 arranged on the right side of the package supply mechanism 3, namely, a first sorting mechanism 41, a second sorting mechanism 42 and a third sorting mechanism 43 from near to far from the package supply mechanism 3. The first sorting mechanism 41 includes a first sorting assembly, which includes a first sorting trolley 51, a first sorting transmission unit 91, a first transfer unit 61 and a first material receiving unit 71. The second sorting mechanism 42 includes a second sorting assembly, which includes a second sorting trolley 52, a second sorting transmission unit 92, a second transfer unit 62 and a second material receiving unit 72. The third sorting mechanism 43 includes a third sorting assembly, which includes a third sorting trolley 53, a third sorting transmission unit 93, a third transfer unit 63 and a third material receiving unit 73.

[0092] In each sorting mechanism 4, the transfer unit 6 is arranged on a side close to the package supply mechanism 3, and the receiving unit 7 is arranged on a side away from the package supply mechanism 3. Those skilled in the art may also adjust the relative positions of the transfer unit 6 and the receiving unit 7 as needed, such as arranging the receiving unit 7 on a side close to the package supply mechanism 3.

[0093] After receiving the objects from the package supply platform 31 , the package supply trolley 33 transports the objects to the first transfer unit 61 of the first sorting mechanism 41 adjacent to the package supply mechanism 3 .

[0094] When the object needs to be delivered to the first receiving unit 71 , the first sorting trolley 51 is driven by the first sorting transmission unit 91 to move to the first transfer unit 61 to receive the object, and then moves to the first receiving unit 71 for delivery.

[0095] When the object needs to be delivered to the second receiving unit 72, the first sorting trolley 51 receives the object from the first transfer unit 61 and then transports the object to the second transfer unit 62; the second sorting trolley 52, driven by the second sorting transmission unit 92, first moves to the second transfer unit 62 to receive the object, and then moves to the second receiving unit 72 for delivery.

[0096] When the object needs to be delivered to the third material receiving unit 73, the first sorting trolley 51 receives the object from the first transfer unit 61, and then transports the object to the second transfer unit 62. The second sorting trolley 52 transports the object from the second transfer unit 62 to the third transfer unit 63. The third sorting trolley 53, driven by the third sorting transmission unit 93, first moves to the third transfer unit 63 to receive the object, and then moves to the third material receiving unit 73 for delivery.

[0097] Those skilled in the art can increase or decrease the number of sorting mechanisms 4 based on the first embodiment as needed, and the working principle of the relay transmission between a larger number of sorting mechanisms 4 is analogous to the above. Each package supply mechanism 3 has one or more package supply tables 31, and those skilled in the art can select them as needed. In the first embodiment, the package supply mechanism 3 is arranged at the end of the translation track 1, which includes a package supply table 31 arranged at the front or rear side of the end of the translation track 1, or includes two package supply tables 31 symmetrically arranged about the front and rear end of the translation track 1. Correspondingly, the package supply transmission unit 34 is used to drive a package supply trolley 33 to reciprocate between the package supply table 31 and the first transfer unit 61.

[0098] Figure 2 and Figure 3The second embodiment of the sorting system of the present invention is shown. The difference between the second embodiment and the first embodiment is that a plurality of sorting mechanisms 4 are arranged on the left and right sides of the package supply mechanism 3 along the extension direction of the translation track 1, and the package supply mechanism 3 is arranged at the non-end part of the translation track 1, preferably in the middle of the translation track 1. The package supply mechanism 3 includes four package supply platforms 31, and the four package supply platforms 31 are symmetrically arranged about the translation track 1 along the horizontal width direction of the translation track 1. Correspondingly, the package supply transmission unit 34 is used to drive two package supply carts 33 to reciprocate between the package supply platform 31 and two adjacent transfer units 6 on the left and right. The number of sorting mechanisms 4 located on both sides of the package supply mechanism 3 can be the same or different.

[0099] Figure 4 and Figure 5 The third embodiment of the sorting system of the present invention is shown. In the third embodiment, the translation track is in a broken line shape, including multiple connecting segments connected end to end, and the multiple connecting segments are arranged in a bow shape, and the angle between two adjacent connecting segments is 90°. The package supply mechanism 3 is arranged at one end of the translation track, and a sorting mechanism 4 is correspondingly provided at each connecting segment. The transfer unit in each sorting mechanism 4 is arranged at one end of the connecting segment, so as to facilitate docking with the package supply mechanism 3 or the adjacent sorting mechanism 4.

[0100] Figure 6 The fourth embodiment of the sorting system of the present invention is shown. The translation track in the fourth embodiment is also in a broken line shape, including multiple first-connected connecting segments, and the angle between two adjacent connecting segments is 90°. The difference between the fourth embodiment and the third embodiment is that the multiple connecting segments are arranged in a stepped manner.

[0101] In addition to the above-mentioned embodiment 3 and embodiment 4, a plurality of connecting sections may also be arranged in an L shape.

[0102] Figure 6 The fifth embodiment of the sorting system of the present invention is shown. In the fifth embodiment, the translation track is T-shaped, including a first branch extending in the front-to-back direction and two second branches extending in the left-to-right direction. The package supply mechanism 3 is arranged at one end of the first branch or the second branch.

[0103] Figure 7 The sixth embodiment of the sorting system of the present invention is shown. In the sixth embodiment, the translation track is maze-shaped, including a first branch extending in the front-to-back direction and a plurality of second branches extending in different horizontal directions. The second branches are all connected to the first branches, and the package supply mechanism 3 is arranged at one end of the first branch.

[0104] Furthermore, if Figure 1As shown, the package supply transmission unit 34 includes a package supply transmission member connected to the package supply trolley 33; the sorting transmission unit 9 includes a sorting transmission member connected to the sorting trolley 5. The package supply transmission member and the sorting transmission member can be a ball screw driven by a motor, and its slider is connected to the package supply trolley 33 / sorting trolley 5; or a cable, rope, belt or chain arranged between a pair of driving wheels and a driven wheel.

[0105] In the first embodiment and the third to fifth embodiments, the package supply transmission member extends from the package supply platform 31 to the transfer unit 6 adjacent thereto; in the second embodiment, the package supply transmission member extends from the transfer unit 6 adjacent thereto on the left side to the transfer unit 6 adjacent thereto on the right side. In the adjacent package supply mechanism 3 and sorting mechanism 4, the package supply transmission member and the sorting transmission member have an overlapping section at the transfer unit 6, so the package supply trolley 33 can reciprocate along the translation track 1 between the package supply platform 31 and the transfer unit 6 of the sorting mechanism 4 adjacent to the package supply mechanism 3.

[0106] The sorting transmission member at the non-end position of the translation track 1 extends from the transfer unit 6 of the sorting mechanism 4 to which it belongs to to the transfer unit 6 of the sorting mechanism 4 adjacent to it and relatively far away from the package supply mechanism 3, that is, in two adjacent sorting mechanisms 4, the two sorting transmission members have overlapping sections at the transfer unit 6 far away from the package supply mechanism 3. Therefore, the sorting trolley 5 at the non-end position of the translation track 1 can reciprocate along the translation track 1 between the transfer unit 6 and the material receiving unit 7 of the same sorting mechanism 4 to complete an item delivery, and can also reciprocate along the translation track 1 between the transfer units 6 of two adjacent sorting mechanisms 4 to realize the relay transmission of objects; the sorting transmission member at the end position of the translation track 1 extends from the transfer unit 6 of the sorting mechanism 4 to which it belongs to to the material receiving unit 7 of the same sorting mechanism 4. Therefore, the sorting trolley 5 at the end position of the translation track 1 can reciprocate between the transfer unit 6 and the material receiving unit 7 of the same sorting mechanism 4.

[0107] It can be seen from the combination of the first to sixth embodiments that the sorting system provided by the present invention can achieve unlimited capacity expansion on the horizontal plane by increasing the number of sorting mechanisms 4 arranged along the translation track 1, and complete single-layer package supply and single-layer sorting.

[0108] Furthermore, in order to improve the sorting efficiency of the sorting system and realize the functions of single-layer package supply and multi-layer sorting, such as Figure 1-4As shown, the sorting system of the present invention also includes a fixed rack 2, and N groups of translation rails 1 are arranged at intervals along the height direction of the rack 2, and each group of translation rails 1 includes one translation rail 1 or two parallel translation rails 1. Compared with moving along one translation rail 1, the movement of the sorting trolley 5 along two translation rails 1 at the same time is undoubtedly more stable. The N groups of translation rails 1 divide the rack 2 into N layers, and the package supply mechanism 3 includes N package supply components arranged at intervals along the height direction of the rack 2, and the sorting mechanism 4 includes N sorting components arranged at intervals along the height direction of the rack 2, and N is an integer greater than or equal to 2. There is a one-to-one correspondence between the N package supply components, the N sorting components and the N groups of translation rails 1, that is, the package supply mechanism 3 is provided with a package supply component on each layer, and the sorting mechanism 4 is provided with a sorting component on each layer, to ensure that objects can be directly transferred or relayed along a group of translation rails 1 in each layer.

[0109] The package supply mechanism 3 also includes a package supply lifting unit 32 arranged between the package supply platform 31 and the frame 2. The package supply lifting unit 32 includes a liftable package supply lifting trolley, which is used to transport multiple objects provided by the package supply platform 31 to the package supply trolleys 33 of different package supply components. Each sorting mechanism 4 also includes a sorting lifting unit 8. The sorting lifting unit 8 and the transfer unit 6 are arranged on different sides of the translation track 1 and the frame 2 along the horizontal width direction of the translation track 1, that is, the corresponding positions of the sorting lifting unit 8 and the transfer unit 6 on the translation track 1 are the same, and the conveyor belt of the sorting trolley 5 or the package supply trolley 33 can be moved in different directions to achieve docking with the sorting lifting unit 8 or the transfer unit 6. The sorting lifting unit 8 includes a liftable sorting lifting trolley and a receiving portion 800 arranged on the outside of the sorting lifting trolley (the "outside" here refers to the side away from the sorting trolley 5). The sorting lift trolley is used to transport objects between sorting trolleys 5 at different heights; the receiving section 800 is used to receive objects that cannot be delivered due to a failure of the sorting component. Specifically, both the package supply lift trolley and the sorting lift trolley have a conveyor belt that can move in the front-to-back direction. The receiving section 800 is fixedly arranged at the bottom of the sorting lift unit 8, and includes one or more storage baskets arranged side by side in the left-right direction.

[0110] The functions of the package supply lifting unit 32 and the sorting lifting unit 8 are described below in conjunction with the first embodiment:

[0111] In the first embodiment, N=5, that is, 5 groups of translation rails 1 are arranged at intervals along the height direction of the rack 2, dividing the rack 2 into 5 layers.

[0112] When the sorting system works normally, the bag supply lifting trolley can transport the objects provided by the bag supply platform 31 to the bag supply trolley 33 on any layer, and then the objects are transferred between the transfer unit 6 and the sorting trolley 5 on the same layer as the bag supply trolley 33, and finally delivered to the material receiving unit 7 on the same layer.

[0113] When a sorting component on the third layer in the first sorting mechanism 41 fails, but objects need to be transported to the second material receiving unit 72 on the third layer in the second sorting mechanism 42, the working process of the sorting system is as follows: the package supply lifting trolley transports the objects provided by the package supply platform 31 to the package supply trolley 33 on the third layer, the package supply trolley 33 moves to the first sorting lifting unit 81 of the first sorting mechanism 41 and transports the objects to the first sorting lifting trolley in the first sorting lifting unit 81, the first sorting lifting trolley transports the objects to the first sorting trolley 51 on the second layer, then the first sorting trolley 51 moves to the second sorting lifting unit 82 of the second sorting mechanism 42, the second sorting lifting trolley of the second sorting lifting unit 82 transports the objects to the second sorting trolley 52 on the third layer, and the second sorting trolley 52 delivers the objects to the second material receiving unit 72 on the third layer.

[0114] When a sorting component on the third layer in the first sorting mechanism 41 fails, but objects need to be transported to the first material receiving unit 71 on the third layer, the working process of the sorting system is as follows: the package supply lifting trolley transports the objects provided by the package supply platform 31 to the package supply trolley 33 on the third layer, the package supply trolley 33 moves to the first sorting lifting unit 81 and transports the objects to the first sorting lifting trolley, the first sorting lifting trolley descends to the vicinity of the receiving section 800, and transports the objects to the receiving section 800.

[0115] As can be seen from the above, compared with a sorting system with a single-layer structure that can only achieve unlimited expansion on the horizontal plane, a sorting system with a multi-layer structure can not only expand in the vertical direction to increase the sorting volume, but also allow the package supply cart 33 and the sorting cart 5 on different layers to work at the same time, realizing the functions of single-layer package supply and multi-layer sorting, which greatly improves the sorting efficiency of objects. At the same time, the present invention sets a sorting lifting unit 8 in each sorting mechanism 4, which can not only realize the detour of the fault layer in the relay transmission, but also accommodate the objects that cannot be delivered, thereby avoiding the normal operation of the entire sorting system affected by the failure of a single sorting component, reducing the maintenance frequency of the sorting system, and further ensuring the efficient operation of the sorting system.

[0116] Specifically, Figure 1 and Fig. 9As shown, the bag supply platform 31 includes a bag supply frame 310 with a bag supply area 3101, and multiple groups of conveying components assembled in the bag supply area 3101 along the front-to-back direction, each group of conveying components includes a conveying drive source, a pair of supporting rollers, and a conveying belt 311 connected to the outer periphery of the pair of supporting rollers, the supporting rollers are rotatably supported in the bag supply frame 310, and are drivingly connected to the conveying drive source, and a triangular area 312 is formed between two adjacent groups of conveying components. After being conveyed by the conveying belts 311 of the multiple groups of conveying components, the objects are conveyed to the bag supply lifting trolley or the bag supply trolley 33.

[0117] Preferably, the supporting roller is a small-diameter roller with a diameter of no more than 40 mm. Since the supporting roller is a small-diameter roller with a diameter of no more than 40 mm, it can greatly reduce the size of the triangular-shaped area 312 formed between the two adjacent groups of conveying components, making the connection between the two adjacent groups of conveying components smoother, effectively preventing the small-volume sorted objects from being stuck in the triangular-shaped area 312, ensuring that the objects can pass through multiple groups of conveying components smoothly, and greatly reducing the probability of dropped objects.

[0118] like Fig.10 As shown, the sorting trolley 5 includes a bracket, on which one or more conveying parts are provided. Each conveying part includes a plurality of rollers 501 rotatably mounted on the bracket and a conveyor belt 502 connected between the plurality of rollers 501. One or more rollers 501 in each conveying part are motorized rollers or connected to a rotating drive source. When the rollers 501 rotate, the conveyor belt 502 moves forward or backward. When a plurality of conveying parts are provided on the bracket, the plurality of conveying parts are spaced apart on the bracket along the left and right directions. Sorting personnel can place objects of different sizes or types on different conveyor belts 502 of the same sorting trolley 5 as needed, so as to increase the number of objects transported by each sorting trolley 5 at a time, and control the operation of different conveying parts when the sorting trolley 5 arrives at the designated receiving unit 7 to complete the delivery, thereby improving the sorting efficiency.

[0119] The bracket also includes two baffles 506, which extend along the conveying direction (i.e., the front-to-back direction) of the conveyor belt 502. The two baffles 506 are arranged on the left and right sides of the conveyor belt 502 along the extension direction of the translation track 1, and form a first opening 5041 and a second opening 5042 between the front and rear ends of the conveyor belt 502 respectively; the sorting cart 5 also includes a blocking portion 503 for blocking objects placed on the conveyor belt from passing through the first opening 5041 and / or the second opening 5042.

[0120] In the first embodiment of the blocking portion 503, the blocking portion 503 includes two blocking units, which are respectively arranged at the first opening 5041 and the second opening 5042. Each blocking unit includes a gate 5031 and a driving source 5032, and the driving source 5032 is used to drive the gate 5031 to move closer to or away from the first opening 5041 or the second opening 5042. The bracket is also provided with a plurality of translation wheels 505 slidably arranged in the grooves of the translation track 1.

[0121] When the sorting trolley 5 receives / delivers materials, the driving source 5032 drives the gate 5031 to move away from the first opening 5041 / the second opening 5042, and the materials can smoothly pass through the first opening 5041 / the second opening 5042 to enter or leave the conveyor belt 502; when the sorting trolley 5 transports materials, the driving source 5032 drives the gate 5031 to move to the bottom of the first opening 5041 / the second opening 5042, and the materials placed on the conveyor belt 502 will be blocked by the gate 5031 and cannot fall down through the first opening 5041 / the second opening 5042.

[0122] The driving source 5032 may be a linear displacement driving source or a rotation driving source. When the driving source 5032 is a linear displacement driving source, it drives the gate 5031 to move up and down, allowing the gate 5031 to move back and forth in a straight line within the range from the bottom of the first opening 5041 / second opening 5042 to the top of the first opening 5041 / second opening 5042. The linear displacement driving source may specifically be a lead screw motor, an electromagnet, etc. When the driving source 5032 is a rotation driving source, it drives the gate 5031 to rotate, allowing the gate 5031 to rotate within the range from the bottom of the first opening 5041 / second opening 5042 to the left side / right side of the first opening 5041 / second opening 5042. The rotation driving source may specifically be a stepping motor or a servo motor.

[0123] In the second embodiment of the blocking part 503, the blocking part 503 is arranged on the conveyor belt 502, and includes a plurality of blocking members arranged on the conveyor belt 502 at intervals along the extension direction of the conveyor belt 502. The blocking member extends along the width direction of the conveyor belt 502, and its specific shape is not limited, and can be strip, plate, block, column or irregular shape. When the sorting trolley 5 receives / delivers materials, the roller 501 drives the conveyor belt 502 to move forward, so that one of the blocking members is located at the bottom of the conveyor belt 502, and the other blocking member is located at the top of the conveyor belt 502, and the materials can smoothly pass through the first opening 5041 / the second opening 5042 to enter or leave the conveyor belt 502; when the sorting trolley 5 transports materials, the roller 501 drives the conveyor belt 502 to move backward, at this time, both blocking members are located at the top of the conveyor belt 502, and the materials are located between the two blocking members, and the forward and backward movement of the materials will be blocked by the blocking members, and they cannot fall down through the first opening 5041 / the second opening 5042.

[0124] like Figure 1 As shown, the transfer unit 6 includes one or more transfer trolleys, and the transfer trolley has a conveyor belt that can move in the front-rear direction. When multiple transfer trolleys are provided in each transfer unit 6, the multiple transfer trolleys are arranged at intervals along the extension direction of the translation track 1.

[0125] Furthermore, the structures of the aforementioned package supply trolley 33 , transfer trolley, package supply lifting trolley and sorting lifting trolley are the same as that of the sorting trolley 5 .

[0126] Furthermore, the package supply lifting unit 32 and the sorting lifting unit 8 have the same structure, and both include one or more lifting components. Each lifting component includes a fixed frame, which is rectangular and has a lifting drive source on its top, which drives the lifting synchronization shaft to rotate. Two lifting driving wheels are provided on the lifting synchronization shaft, and two lifting driven wheels are provided at the bottom of the fixed frame. A lifting transmission member is provided between the lifting driving wheel and the lifting driven wheel on the same side, and a lifting frame is connected between the two lifting transmission members. A package supply lifting trolley / sorting lifting trolley is fixedly connected to the lifting frame. When the lifting drive source drives the lifting synchronization shaft to rotate, it can drive the lifting frame and the package supply lifting trolley / sorting lifting trolley arranged between the two lifting transmission members to perform lifting movements at the same time. The lifting drive source can specifically be a stepper motor or a servo motor.

[0127] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
