[0004] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides a cargo delivery and sorting system based on serial sorting units with convenient configuration and reasonable layout.

[0005] Technical solution: To achieve the above-mentioned purpose, the utility model is a cargo delivery and sorting system based on serial sorting units, which includes a vertical support, a plurality of serially connected sorting units, and a driving device for driving the sorting units to rotate around the vertical support; upper and lower sides of the vertical support are respectively provided with an upper guide rail and a lower guide rail; and the utility model also includes a loading station and a temporary storage shelf located outside the lower guide rail, wherein the temporary storage shelf has a plurality of delivery grids arranged in two dimensions along the extension direction and height direction of the lower guide rail;

[0006] The sorting unit has a vertical frame, and the upper and lower sides of the vertical frame are respectively provided with an upper running wheel assembly and a lower running wheel assembly capable of running along the upper guide rail and the lower guide rail; the sorting unit also includes a delivery unit capable of controllably lifting and lowering movement relative to the vertical frame;

[0007] The driving device includes an electromagnetic driving part installed on the vertical support and a magnetic plate part installed on the sorting unit. The electromagnetic driving part has coils arranged in an equidistant array on the running path of the sorting unit, and the magnetic plate part has magnets arranged in an equidistant array. When the electromagnetic driving part is energized, the coil generates a magnetic field to drive the magnetic plate part to move, thereby driving the sorting unit.

[0008] During operation, the loading station has manual and / or loading machinery to perform loading operations. After the sorting unit arrives at the loading station, its delivery unit accepts the goods provided by the loading station. The control system raises and lowers the delivery unit to the target height based on the height of the target delivery grid of the goods during the running of the sorting unit along the running path. After the sorting unit arrives at the location of the delivery grid, the delivery unit outputs the goods to the target delivery grid to achieve the sorting of the goods. Multiple sorting units operating together can achieve the delivery and sorting of multiple goods in one cycle, improving the sorting efficiency.

[0009] Furthermore, the upper guide rail and the lower guide rail are both oval in shape.

[0010] Furthermore, the number of the upper guide rail is one; the upper walking wheel assembly includes an upper supporting wheel in contact with the top of the upper guide rail, and also includes two upper side wheels in contact with both sides of the upper guide rail respectively;

[0011] The number of the lower guide rails is two, and the lower walking wheel assembly includes lower supporting wheels respectively contacting the tops of the two lower guide rails, and also includes two lower side wheels placed between the two lower guide rails and respectively contacting the two lower guide rails.

[0012] The above-mentioned single upper guide rail and double lower guide rail design can improve the support stability of the sorting unit. In addition, since all sorting units are connected in series, the upper running wheel assemblies and lower running wheel assemblies of all sorting units can form a running wheel group, forming an overall support for the entire sorting unit group, thus reducing the number of upper running wheel assemblies and lower running wheel assemblies used.

[0013] Furthermore, the number of the upper guide rail and the number of the lower guide rail are both one, and the structure of the upper walking wheel assembly is the same as that of the lower walking wheel assembly; the upper walking wheel assembly includes an upper supporting wheel in contact with the top of the upper guide rail, and also includes two upper side wheels in contact with both sides of the upper guide rail respectively.

[0014] Furthermore, in the upper walking wheel assembly, the distance between the two upper side wheels can be elastically changed.

[0015] Further, the upper traveling wheel assembly further comprises an upper wheel frame, a first wheel frame is rotatably mounted on the upper wheel frame, and the upper supporting wheel is rotatably mounted on the first wheel frame;

[0016] The lower walking wheel assembly also includes a lower wheel frame, on which a second wheel frame for each lower supporting wheel is rotatably mounted, and each lower supporting wheel is rotatably mounted relative to the corresponding second wheel frame. With the above-mentioned mounting structure, at the turning position of the guide rail, the first wheel frame and the second wheel frame can rotate adaptively to reduce turning resistance.

[0017] Furthermore, the vertical support has a first plate body on which the electromagnetic driving part is installed; the sorting unit has a second plate body on which the magnetic plate part is installed; one of the first plate body and the second plate body is installed with a roller assembly acting on the other, and the roller assembly is connected to the plate body where it is located through a bending bracket capable of generating elastic deformation. The driving device also includes an encoder installed on the first plate body, and the control system can accurately know the position of the sorting unit through the data collected by the encoder, and can control the delivery unit to deliver the goods to the correct grid.

[0018] Furthermore, each of the sorting units is equipped with a serial connection mechanism; the serial connection mechanism includes a first connection unit and a second connection unit; and among two adjacent sorting units, the first connection unit of one is connected to the second connection unit of the other.

[0019] Furthermore, the first connecting unit includes a pin; the second connecting unit includes a connecting frame and a ball bearing installed on the connecting frame; the ball bearing is connected to the pin.

[0020] Furthermore, the first connection unit also includes a guide sleeve installed on the vertical frame, and the pin shaft can slide up and down relative to the guide sleeve; the middle part of the ball bearing is fixed relative to the pin shaft.

[0021] Furthermore, the delivery unit is a conveyor belt assembly, a conveyor roller assembly, or a flap assembly.

[0022] Furthermore, the delivery unit is driven by a synchronous belt mechanism to rise and fall relative to the vertical frame.

[0023] Beneficial effects: The cargo delivery and sorting system based on the serial sorting monomer of the utility model has the following beneficial effects:

[0024] (1) The system structure is reasonably laid out. The sorting unit has an upper running wheel assembly and a lower running wheel assembly running along the upper and lower guide rails respectively, and its operation is stable and reliable.

[0025] (2) The sorting units are connected in series and can be increased or decreased as needed, with flexible configuration.

[0026] (3) The sorting unit is driven to run by an electromagnetic propulsion part fixed on a vertical bracket. Only the magnetic plate part needs to be installed on the sorting unit, and there is no need to equip it with a walking drive device that needs to be powered on. This can make the sorting unit structure smaller and lighter, and the increase in the number of sorting units does not require an increase in the number of electromagnetic propulsion parts.

[0027] (4) The roller assembly can prevent the electromagnetic pushing part and the magnetic plate part from contacting each other, and the bending bracket can be elastically deformed as needed to control the gap between the electromagnetic pushing part and the magnetic plate part, so that the gap between the two is maintained at an optimal working distance to ensure sufficient magnetic thrust. In addition, the setting of the roller assembly can reduce resistance.

[0028] (5) The use of a series connection structure to connect the sorting units is not only convenient for quick disassembly and assembly, but also because the ball bearing has multi-directional rotation freedom and the pin shaft has sliding freedom, the relative posture between adjacent sorting units can be relatively adaptively fine-tuned during the movement of the sorting units to prevent jamming and ensure smooth operation.

DETAILED DESCRIPTION

[0043] The utility model is further described below in conjunction with the accompanying drawings.

[0044] like Figure 1 and Figure 2 The cargo delivery and sorting system based on serial sorting units shown in the figure comprises a vertical support 1, a plurality of serially connected sorting units 2, and a driving device 3 for driving the sorting units 2 to rotate around the vertical support 1; an upper guide rail 4 and a lower guide rail 5 are respectively installed on the upper and lower sides of the vertical support 1.

[0045] It also includes a loading station 6 and a temporary storage shelf 7 located outside the lower guide rail 5. The temporary storage shelf 7 has a plurality of delivery grids arranged in two dimensions along the extension direction and height direction of the lower guide rail 5.

[0046] The sorting unit 2 has a vertical frame 21, and the upper and lower sides of the vertical frame 21 are respectively provided with an upper running wheel assembly 22 and a lower running wheel assembly 23 capable of running along the upper guide rail 4 and the lower guide rail 5; the sorting unit 2 also includes a delivery unit 24 capable of controllable lifting and lowering movement relative to the vertical frame 21. The delivery unit 24 is a conveyor belt assembly or a conveyor roller assembly or a flap assembly. In the illustrated embodiment, the delivery unit 24 is a conveyor belt assembly. The delivery unit 24 is driven by a synchronous belt mechanism to rise and fall relative to the vertical frame 21.

[0047] like Figure 4 As shown, the driving device 3 includes an electromagnetic driving part 31 installed on the vertical support 1 and a magnetic plate part 32 installed on the sorting unit 2. Figure 3 As shown, the electromagnetic driving part 31 has a plurality of coils 31a arranged on the running path of the sorting unit 2, and the magnetic plate part 32 has magnets arranged in an equidistant array. When the electromagnetic driving part 31 is energized, the coil generates a magnetic field to drive the magnetic plate part 32 to move, thereby driving the sorting unit 2.

[0048] In the illustrated embodiment, the upper guide rail 4 and the lower guide rail 5 are both oval in shape, so that more delivery slots can be arranged. In other embodiments, the guide rails can also be set to other shapes as needed.

[0049] The above system has a reasonable structure layout, and the sorting unit 2 has an upper running wheel assembly 22 and a lower running wheel assembly 23 running along the upper and lower guide rails respectively, and its operation is stable and reliable. The sorting units 2 are connected in series, and can be increased or decreased as needed, and the sorting units 2 are driven to run by the electromagnetic driving part 31 fixed on the vertical bracket 1. Only the magnetic plate part 32 needs to be installed on the sorting unit 2, and there is no need to equip the running driving device that needs to be powered on, which can make the structure of the sorting unit 2 small and lightweight, and the increase in the number of sorting units 2 does not require the increase in the number of electromagnetic driving parts 31, and flexible configuration can be achieved.

[0050] During operation, the loading station 6 has manual and / or loading machinery to perform loading operations. After the sorting unit 2 arrives at the loading station 6, its delivery unit 24 receives the goods provided by the loading station 6. The control system, based on the height of the target delivery grid corresponding to the goods, raises and lowers the delivery unit 24 to the target height during the operation of the sorting unit 2 along the running path. After the sorting unit 2 arrives at the location of the delivery grid, the delivery unit 24 outputs the goods to the target delivery grid to achieve the sorting of the goods. Multiple sorting units 2 can be operated together to achieve the delivery and sorting of multiple goods in one cycle, thereby improving the sorting efficiency.

[0051] In the first embodiment, the number of the upper guide rail 4 is one; Figure 5As shown, the upper walking wheel assembly 22 includes an upper support wheel 22a in contact with the top of the upper guide rail 4, and also includes two upper side wheels 22b in contact with both sides of the upper guide rail 4; Figure 6 As shown, the number of the lower guide rails 5 is two, and the lower walking wheel assembly 23 includes lower supporting wheels 23a respectively contacting the tops of the two lower guide rails 5, and also includes two lower side wheels 23b placed between the two lower guide rails 5 and respectively contacting the two lower guide rails 5.

[0052] The design of the single upper rail and double lower rails can improve the support stability of the sorting unit 2. In addition, since all the sorting units 2 are connected in series, the upper running wheel assemblies 22 and the lower running wheel assemblies 23 of all the sorting units 2 can form a running wheel group to form an overall support for the entire sorting unit group, thus reducing the number of upper running wheel assemblies 22 and lower running wheel assemblies 23 used.

[0053] The upper traveling wheel assembly 22 further comprises an upper wheel frame 22c, on which a first wheel frame 22d is rotatably mounted, and the upper supporting wheel 22a is rotatably mounted on the first wheel frame 22d;

[0054] The lower walking wheel assembly 23 also includes a lower wheel frame 23c, on which a second wheel frame 23d set for each lower supporting wheel 23a is rotatably mounted, and each lower supporting wheel 23a is rotatably mounted relative to the corresponding second wheel frame 23d. With the above-mentioned mounting structure, at the turning position of the guide rail, the first wheel frame 22d and the second wheel frame 23d can rotate adaptively to reduce turning resistance.

[0055] In the second embodiment, if Figure 7 As shown, the number of the upper guide rail 4 and the number of the lower guide rail 5 are both one, and the structure of the upper running wheel assembly 22 and the lower running wheel assembly 23 are the same. The structure of the upper running wheel assembly 22 is described as follows. Figure 8 As shown, in the upper walking wheel assembly 22, one of the upper side wheels 22b is directly hinged on the upper wheel frame 22c, and the other upper side wheel 22b is installed on the floating wheel frame 22e. The floating wheel frame 22e can rotate relative to the upper wheel frame 22c, and an elastic mechanism 22f is arranged between the upper wheel frame 22c and the floating wheel frame 22e. The elastic mechanism 22f exerts a force on the floating wheel frame 22e, so that the two upper support wheels 22a have a tendency to move relatively close to each other. In this way, the two upper support wheels 22a can be tightly attached to the two sides of the upper guide rail 4 under the force of the elastic mechanism 22f. When the width of the upper guide rail 4 changes, the spacing between the two upper support wheels 22a can change adaptively.

[0056] like Fig. 9As shown, the vertical support 1 has a first plate 11 for mounting the electromagnetic pushing part 31; the sorting unit 2 has a second plate 33 for mounting the magnetic plate part 32; one of the first plate 11 and the second plate 33 is mounted with a roller assembly 81 acting on the other, as shown in FIG. Fig.10 As shown, the roller assembly 81 is connected to the plate body where it is located through a bending bracket 82 that can generate elastic deformation. In the embodiment shown in the figure, the roller assembly 81 is installed on the second plate body 33. Fig.11 As shown, the driving device 3 also includes an encoder 34 installed on the first plate body 11. The control system can accurately know the position of the sorting unit 2 through the data collected by the encoder 34, and can control the delivery unit 24 to deliver the goods to the correct grid. Through the above structure, the roller assembly 81 can prevent the electromagnetic driving part 31 and the magnetic plate part 32 from contacting each other, and the bending bracket 82 can be elastically deformed as needed to control the gap between the electromagnetic driving part 31 and the magnetic plate part 32, so that the gap between the two is maintained at the optimal working distance to ensure sufficient magnetic thrust. In addition, the setting of the roller assembly 81 can reduce resistance.

[0057] Each of the sorting units 2 is equipped with a series connection mechanism; Fig.12 and Fig.13 As shown, the serial connection mechanism includes a first connection unit 91 and a second connection unit 92; among two adjacent sorting units 2, the first connection unit 91 of one is connected to the second connection unit 92 of the other.

[0058] Preferably, the first connection unit 91 includes a pin shaft 91a; the second connection unit 92 includes a connection frame 92a and a ball bearing 92b mounted on the connection frame 92a; the ball bearing 92b is connected to the pin shaft 91a. The first connection unit 91 also includes a guide sleeve 91b mounted on the vertical frame 21, the pin shaft 91a can slide up and down relative to the guide sleeve 91b; the middle part of the ball bearing 92b is fixed relative to the pin shaft 91a.

[0059] The above-mentioned series connection structure is not only easy to disassemble, but also because the ball bearing 92b has multi-directional rotation freedom and the pin shaft 91a has sliding freedom, during the movement of the sorting unit 2, the relative posture between adjacent sorting units 2 can be relatively adaptively fine-tuned to prevent jamming and ensure smooth operation.

[0060] 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 modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
