Description

Technical Field

[0001] The utility model relates to the technical field of sorting of commodities, express items and the like, in particular to a sorting and feeding mechanism and a sorting system comprising the sorting and feeding mechanism. Background Art

[0002] The automatic express sorting system can automatically transport each express package among multiple express packages to the corresponding grid, and automatically sort large quantities of express packages continuously. It has the advantages of high sorting efficiency and low sorting error rate, and is widely used in logistics distribution centers.

[0003] Usually, the express automatic sorting system includes a fixed frame and a sorting and feeding mechanism that are all fixedly installed, a mobile frame that is movably installed on the fixed frame along the length direction of the fixed frame, a sorting trolley that is movably installed on the mobile frame along the height direction of the fixed frame, and a receiving mechanism arranged on the outer side of the fixed frame along the width direction of the fixed frame. The fixed frame is provided with multiple grid openings (i.e., material drop chutes), and the receiving mechanism is provided with multiple receiving frames, and the multiple receiving frames correspond to the multiple grid openings one by one. When the express automatic sorting system is in operation, the sorting personnel only need to place multiple express items on the sorting and feeding mechanism, and the sorting trolley moves to the sorting and feeding mechanism to receive the express items. The sorting trolley then moves to the corresponding grid opening according to the information on the express items, and the sorting trolley moves the express items out, and the express items slide into the corresponding receiving frame through the grid opening. The automatic sorting of multiple express items is realized by the reciprocating movement of the sorting trolley between the sorting and feeding mechanism and the grid opening.

[0004] In the prior art, the sorting and feeding mechanism mainly includes a frame and a belt conveyor mechanism installed on the frame. The sorting personnel place the express on the conveyor belt of the belt conveyor mechanism, and the belt conveyor mechanism transports the express to the designated position for the sorting cart to pick up the material. For example: a multi-axis double-trolley automatic sorting device disclosed in the Chinese invention patent application with application number 202211171868.9, and the sorting and feeding mechanism disclosed therein. If only one set of belt conveyor mechanisms is configured in the sorting and feeding mechanism, it is easy for express to accumulate at the end of the conveyor belt due to the single conveying speed. If multiple sets of belt conveyor mechanisms are configured in the sorting and feeding mechanism, it can play a certain caching role to prevent express from accumulating at the end of the conveyor belt; however, the spacing between the multiple sets of belt conveyor mechanisms is large, and there is a risk of falling pieces.

[0007] Along the conveying direction of the feeding conveyor belt, multiple groups of feeding belt conveyor mechanisms are connected in sequence and are distributed in a stepped manner from high to low, and two adjacent groups of feeding belt conveyor mechanisms are arranged closely.

[0008] Furthermore, each group of feeding belt conveyor mechanisms also includes a detection unit installed on the feeding frame, and the detection unit is used to detect whether there are objects passing on the feeding conveyor belt of the group of feeding belt conveyor mechanisms.

[0009] Further, the feeding rack includes a rack frame, and a pair of rack baffles fixed to the upper end of the rack frame, wherein the pair of rack baffles are relatively distributed on both sides of the feeding conveyor belts of the multiple groups of feeding belt conveyor mechanisms in a direction perpendicular to the conveying direction of the feeding conveyor belts, and are higher than the feeding conveyor belts of the multiple groups of feeding belt conveyor mechanisms;

[0010] The detection unit includes a grating sensor fixed on the outside of the frame baffle and a detection opening opened in the frame baffle, wherein the detection opening allows the grating sensor to be exposed.

[0011] Furthermore, in each set of feeding belt conveyor mechanisms, the bottom of the detection opening is flush with the top of the feeding conveyor belt.

[0012] Furthermore, along the conveying direction of the loading conveyor belt, a material taking avoidance area is provided at the head end of the frame baffle.

[0013] Furthermore, the feeding drive source is a motor and is staggered with the active roller. Each group of feeding belt conveyor mechanisms also includes a transmission unit, and the feeding drive source is connected to the active roller via the transmission unit.

[0014] Furthermore, the transmission unit includes a driving pulley fixed on the motor shaft of the feeding drive source, a driven pulley fixed on the end of the driving roller, and a transmission belt connected to the outer periphery of the driving pulley and the driven pulley.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0052] The utility model provides a sorting and feeding mechanism and a sorting system comprising the sorting and feeding mechanism, which are used for automatically sorting a plurality of sorted objects (such as express mail, commodities, etc.).

[0053] like Figure 1 and Figure 2As shown, the sorting and feeding mechanism involved in the present application includes a feeding frame 10, and a plurality of feeding belt conveyor mechanisms 20 all mounted on the feeding frame 10. Each group of feeding belt conveyor mechanisms 20 includes a feeding drive source 21 mounted on the feeding frame 10, an active roller 22 and a driven roller 23 rotatably mounted on the feeding frame 10, and a feeding conveyor belt 24 connected to the outer periphery of the active roller 22 and the driven roller 23. The feeding drive source 21 is transmission-connected to the active roller 22, and the feeding drive sources 21 in the plurality of feeding belt conveyor mechanisms 20 are independent of each other. For the convenience of description, in the following embodiments, the conveying direction of the feeding conveyor belt 24 is defined as the front direction, and the direction perpendicular to the conveying direction of the feeding conveyor belt 24 is defined as the left-right direction. Based on this, in each group of feeding belt conveyor mechanisms 20, the active roller 22 and the driven roller 23 extend left and right and are arranged side by side front and back. Along the conveying direction of the sorted objects being conveyed forward by the loading conveyor belt 24, multiple groups of loading belt conveyor mechanisms 20 are connected in sequence from back to front and are distributed in a stepped manner from high to low. The loading belt conveyor mechanism 20 distributed on the rear side is the highest, and the loading belt conveyor mechanism 20 distributed on the front side is the lowest; and the front and rear adjacent groups of loading belt conveyor mechanisms 20 are arranged closely.

[0054] The above-mentioned sorting and feeding mechanism has multiple groups of feeding belt conveyor mechanisms 20, and each group of feeding belt conveyor mechanisms 20 is driven by an independent feeding drive source 21, so that the conveying speed of the feeding conveyor belt 24 of each group of feeding belt conveyor mechanisms 20 is independently controlled, so that the buffering of the sorted objects on the multiple groups of feeding belt conveyor mechanisms 20 can be better controlled, and the sorted objects can be prevented from being excessively accumulated at the front end of the sorting and feeding mechanism, thereby improving the efficiency of the equipment. At the same time, the present application arranges the multiple groups of feeding belt conveyor mechanisms 20 in a stepped distribution, and the height of the multiple groups of feeding belt conveyor mechanisms 20 decreases from back to front, that is, the two adjacent groups of feeding belt conveyor mechanisms 20 are displaced up and down, which can better arrange the two adjacent groups of feeding belt conveyor mechanisms 20 close to each other, reduce the gap between the two adjacent groups of feeding belt conveyor mechanisms 20 in front and behind, and avoid falling parts. Furthermore, after the multiple groups of feeding belt conveyor mechanisms 20 are arranged in a stepped distribution structure from high to low, it is possible to avoid the formation of a groove in the middle part of the feeding conveyor belt 24, thereby preventing the light sorted objects from jumping on the feeding conveyor belt 24, thereby ensuring the reliability of feeding.

[0055] Preferably, the number of the feeding belt conveyor mechanisms 20 in the sorting and feeding mechanism is determined according to actual needs, and can be 2 groups, 3 groups, 4 groups or more; Figure 1 In the illustrated embodiment, there are three groups of feeding belt conveyor mechanisms 20 .

[0056] Further, the preferred structure of the loading rack 10 is: Figure 1As shown, the loading rack 10 includes a rack frame 11, and a pair of rack baffles 12 fixed to the upper end of the rack frame 11. The pair of rack baffles 12 are relatively distributed on the left and right sides of the loading conveyor belts 24 of the multiple groups of loading belt conveyor mechanisms 20 in a direction perpendicular to the conveying direction of the loading conveyor belts 24. At the same time, the rack baffles 12 are also higher than the loading conveyor belts 24 of the multiple groups of loading belt conveyor mechanisms 20. By providing the rack baffles 12, it is possible to prevent the sorted objects on the loading conveyor belt 24 from falling from the left and right sides, thereby improving the reliability of the forward conveyance of the sorted objects.

[0057] Furthermore, if Figure 1 As shown, each group of feeding belt conveyor mechanisms 20 also includes a detection unit installed on the feeding frame 10, and the detection unit is used to detect whether there is an object passing on the feeding conveyor belt 24 of the group of feeding belt conveyor mechanisms 20. In this way, it is possible to detect the first sorted object passing forward on the sorting feeding mechanism and the last sorted object passing forward, so as to be used for sorting start control and sorting shut-down control; at the same time, it is also possible to detect the length of the sorted object conveyed on the sorting feeding mechanism. When the length of the sorted object exceeds the threshold, it is judged as misplaced, and an alarm will be issued at this time, thereby improving the safety of the operation.

[0058] Preferably, if Figure 1 As shown, the detection unit includes a grating sensor 30 fixed on the outside of the frame baffle 12, and a detection opening 13 opened in the frame baffle 12, and the detection opening 13 allows the grating sensor 30 to be exposed. In addition, in each set of feeding belt conveyor mechanism 20, the bottom of the detection opening 13 is flush with the top of the feeding conveyor belt 24, so that it can more reliably detect whether there is an object passing on the feeding conveyor belt 24.

[0059] Furthermore, if Figure 1 As shown, along the conveying direction of the sorted objects conveyed forward by the loading conveyor belt 24, a material picking avoidance area 14 is provided at the head end (i.e., the front end) of the frame baffle 12 to prevent the frame baffle 12 from interfering with the picking of the sorting trolley 60 in the sorting system.

[0060] Furthermore, if Figure 1 As shown, the feeding drive source 21 is a motor and is staggered with the driving roller 22. Each group of feeding belt conveyor mechanisms 20 also includes a transmission unit, and the feeding drive source 21 is connected to the driving roller 22 through the transmission unit. Through the staggered distribution structure of the feeding drive source 21 and the driving roller 22, the size of the sorting feeding mechanism in the left and right directions can be reduced, which is convenient for its installation in the sorting system. Preferably, the transmission unit includes a driving pulley 25 fixed on the motor shaft of the feeding drive source 21, a driven pulley 26 fixed on the end of the driving roller 22, and a transmission belt 27 connected to the outer periphery of the driving pulley 25 and the driven pulley 26.

[0061] Furthermore, if Figure 1 and Figure 2 As shown, each group of feeding belt conveyor mechanism 20 also includes an adjustment unit, which includes an adjustment slot 15 provided in the feeding frame 10, an adjustment plate 41 fixed to the feeding frame 10, and an adjustment screw 42 rotatably inserted in the adjustment plate 41. The adjustment slot 15 and the adjustment screw 42 both extend straightly forward and backward along the conveying direction of the feeding conveyor belt 24. The driven roller 23 includes a roller shaft 231 and a roller rotatably mounted on the outer periphery of the roller shaft 231. Both ends of the roller shaft 231 are clamped in the adjustment slot 15 and threadedly connected with the adjustment screw 42. By rotating the adjustment screw 42, the front and rear position of the roller shaft 231 of the driven roller 23 in the adjustment slot 15 can be adjusted, and the front and rear position of the driven roller 23 can also be adjusted, thereby adjusting the tension of the feeding conveyor belt 24 in the group of feeding belt conveyor mechanism 20, so that it can more reliably convey the sorted objects forward.

[0062] Furthermore, the utility model also provides a sorting system, such as Figure 3 As shown, the sorting system includes a fixedly installed fixed frame 50, at least one sorting trolley 60 movably installed on the fixed frame 50, a plurality of blanking chutes 70 all installed on the fixed frame 50, a receiving mechanism 80 arranged on the outer side of the fixed frame 50, and the above-mentioned sorting and loading mechanism; the length direction of the fixed frame 50 is perpendicular to the conveying direction of the loading conveyor belt 24, then the length direction of the fixed frame 50 is the left-right direction, the fixed frame 50 is provided with a loading and packaging station 51, the sorting and loading mechanism is arranged at the loading and packaging station 51 of the fixed frame 50, and the frame frame 11 of the sorting and loading mechanism is fixedly connected to the fixed frame 50; the sorting trolley 60 can reciprocate between the loading and packaging station 51 and the blanking chute 70, and the receiving mechanism 80 has a plurality of receiving frames 81 corresponding to the blanking chutes 70 one by one. Preferably, the movement mode of the sorting trolley 60 on the fixed frame 50 is: left and right translation along the length direction of the fixed frame 50, and translation along the up and down direction. Through the left and right movement and up and down movement of the sorting trolley 60, the sorting trolley 60 reciprocates between the loading and packaging station 51 and the blanking chute 70.

[0063] The working process of the sorting system is as follows: the staff places multiple sorted objects in order on the feeding conveyor belt 24 of the feeding belt conveyor mechanism 20 at the rear side of the sorting and feeding mechanism, and the sorting and feeding mechanism conveys the sorted objects forward; the sorting trolley 60 moves to the sorting and feeding mechanism and moves to the bottom of the front end of the sorting and feeding mechanism to receive the sorted objects output by the front end of the sorting and feeding mechanism; the sorting trolley 60 moves to the blanking chute 70 corresponding to the sorted object on the sorting trolley 60, and the sorting trolley 60 unloads the sorted objects on it, and the sorted objects fall into the receiving frame 81 corresponding to the blanking chute 70 through the blanking chute 70, thereby completing the automatic sorting of the sorted objects; thereafter, the sorting trolley 60 moves to the sorting and feeding mechanism again to sort the next sorted object.

[0064] Furthermore, if Figure 3 As shown, along the length direction of the fixed frame 50, the loading and packaging station 51 and the sorting and loading mechanism can be arranged at the end position of the fixed frame 50, or at the middle position of the fixed frame 50. Preferably, along the length direction of the fixed frame 50, the loading and packaging station 51 and the sorting and loading mechanism are both arranged at the middle position of the fixed frame 50, and the fixed frame 50 is provided with a material drop chute 70 and a material receiving mechanism 80 on both sides of the loading and packaging station 51 and the sorting and loading mechanism, so that the sorting system is a central packaging structure. In this way, after the sorting trolley 60 receives the sorted objects output from the front end of the sorting and loading mechanism, the sorting trolley 60 is translated to the area on the left or right side of the sorting and loading mechanism, which can shorten the moving distance of the sorting trolley 60 in the length direction of the fixed frame 50 during a single sorting, thereby shortening the time required for a single sorting, thereby improving the sorting efficiency.

[0065] In summary, the utility model effectively overcomes various shortcomings of the prior art and has high industrial utilization value.

[0066] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
