Description

Technical Field

[0001] The utility model relates to the technical field of object sorting, in particular to an anti-drop feeding device and a sorting system including the anti-drop feeding device. Background Art

[0002] An automatic object sorting system can automatically convey each of multiple objects (such as express packages) to the corresponding grid opening, and continuously and automatically sort a large number of objects to be sorted, with advantages such as high sorting efficiency and low sorting error rate, and is widely used in logistics distribution centers.

[0003] Generally, an automatic object sorting system includes a feeding device, a fixed frame, a sorting trolley movably installed on the fixed frame, a plurality of grid openings (i.e., blanking chutes) provided in the fixed frame, and a receiving device arranged on the outer side of the fixed frame. The receiving device has a plurality of receiving frames corresponding to the grid openings one by one. When the automatic object sorting system operates, the sorting personnel only need to place a plurality of objects to be sorted on the feeding device. The feeding device conveys the objects to be sorted to the sorting trolley, and the sorting trolley then moves to the corresponding grid opening to unload the materials. Then, the objects to be sorted slide down through the grid opening into the corresponding receiving frame.

[0004] In the prior art, the feeding device used in the automatic object sorting system mainly adopts a belt conveying structure. For example, a sorting machine disclosed in a Chinese design patent with the application number CN202330244013.3. Specifically, the feeding device includes a frame and a plurality of groups of conveying components all installed on the frame. The plurality of groups of conveying components are arranged side by side in the front and back directions along the direction in which the feeding device conveys the objects to be sorted. Each group of conveying components includes a driving motor, a driving roller, a driven roller, and a conveying belt. The driving roller and the driven roller are both rotatably supported in the frame. The driving motor is in transmission connection with the driving roller, and the conveying belt is connected to the outer circumferences of the driving roller and the driven roller.

[0005] In the above-mentioned existing feeding device, there is a triangular-like area between the conveying belts of two adjacent groups of conveying components in the front and back. However, the existing feeding devices all adopt large-diameter driving rollers and driven rollers, resulting in a relatively large triangular-like area. Moreover, in order to ensure that there is no interference between two adjacent groups of conveying components, there must be a certain amount of gap between two adjacent groups of conveying components in the front and back. Thus, when the objects to be sorted conveyed by the feeding device are small objects with a small volume such as lipsticks and pens, when such small objects are conveyed forward to the connection between the front group of conveying components and the rear group of conveying components, the small objects are likely to get stuck in the triangular area here, and the small objects will not be continuously conveyed forward by the rear group of conveying components, ultimately resulting in dropped objects. Summary of the Utility Model

[0006] In view of the above-mentioned disadvantages of the prior art, the technical problem to be solved by the present utility model is to provide a package supply device that prevents parts from falling off, effectively avoiding small-sized sorted objects from getting stuck between two adjacent sets of conveying components in the front and back.

[0007] To achieve the above object, the present utility model provides a package supply device that prevents parts from falling off, which includes a package supply rack provided with a package supply area, and several sets of conveying components assembled in the package supply area. The several sets of conveying components are arranged in the front and back along their conveying directions. Each set of conveying components includes a conveying driving source, a pair of supporting rollers arranged side by side in the front and back along their conveying directions, and a conveying belt connected to the outer circumferences of the pair of supporting rollers. The supporting rollers are rotatably supported in the package supply rack and are in transmission connection with the conveying driving source. A triangular-like area is formed between two adjacent sets of conveying components in the front and back, and the supporting rollers are small-diameter rollers with a diameter not greater than 40 mm.

[0008] Further, the diameter of the supporting rollers is 28 - 32 mm.

[0009] Further, the conveying driving source is a motor. Each set of conveying components further includes a driving roller rotatably supported in the package supply rack, a first pulley fixed on the motor shaft of the conveying driving source, a second pulley fixed on the driving roller, and a synchronous belt connected between the first pulley and the second pulley. The driving roller is in contact and cooperation with the inner circumferential surface of the conveying belt and is distributed on the lower side of the pair of supporting rollers. The diameter of the driving roller is greater than that of the supporting rollers.

[0010] Further, a motor installation area is formed on the outer circumferential side of the conveying belt between one of the pair of supporting rollers and the driving roller. The conveying driving source is located in the motor installation area and is fixed to the package supply rack.

[0011] Further, each set of conveying components further includes a tension adjusting roller and a tension adjusting component. The tension adjusting roller includes a roller shaft portion and a tensioning cylinder portion rotatably assembled on the roller shaft portion. The tensioning cylinder portion is in contact and cooperation with the outer circumferential surface of the conveying belt. The roller shaft portion is installed on the package supply rack through the tension adjusting component so as to be movable back and forth.

[0012] Further, at least one circumferentially extending limiting rib is provided on the outer circumferential surface of the conveying belt; when there are several limiting ribs, the several limiting ribs are arranged side by side in the left and right directions perpendicular to the conveying direction of the conveying components.

[0013] Further, there are several package supply areas in the package supply rack of the present utility model. The several package supply areas are arranged side by side in the left and right directions perpendicular to the conveying direction of the conveying components. Each package supply area is assembled with several sets of conveying components.

[0014] The present utility model also provides a sorting system, which includes a fixed frame provided with a feeding and bagging station, a sorting mechanism installed on the fixed frame, several blanking chutes all installed on the fixed frame, and a receiving mechanism arranged on the outer side of the fixed frame. The receiving mechanism has a plurality of receiving frames corresponding to the blanking chutes one by one; the sorting system further includes the anti-falling part feeding and bagging device as described above, and the anti-falling part feeding and bagging device is installed at the feeding and bagging station of the fixed frame, and the sorting mechanism is connected between the anti-falling part feeding and bagging device and the blanking chute.

[0015] Further, the length direction of the fixed frame is consistent with the conveying direction of the anti-falling part feeding and bagging device, and the anti-falling part feeding and bagging device is arranged at the end of the fixed frame along the length direction of the fixed frame.

[0016] Further, the length direction of the fixed frame is perpendicular to the conveying direction of the anti-falling part feeding and bagging device. The anti-falling part feeding and bagging device is arranged at the middle position of the fixed frame along the length direction of the fixed frame. The fixed frame is provided with blanking chutes and receiving mechanisms on both the left and right sides of the anti-falling part feeding and bagging device.

[0017] Further, the sorting mechanism includes a moving frame movably installed on the fixed frame along the length direction of the fixed frame, and a first sorting trolley liftably installed on the moving frame. The moving frame can reciprocate between the anti-falling part feeding and bagging device and the blanking chute.

[0018] Further, the sorting mechanism includes a second sorting trolley liftably installed on the fixed frame, and several third sorting trolleys arranged vertically. The second sorting trolley can reciprocate between the anti-falling part feeding and bagging device and the several third sorting trolleys. The several third sorting trolleys correspond to the number of layers of the blanking chutes one by one. The several third sorting trolleys are all movably installed on the fixed frame along the length direction of the fixed frame and can reciprocate between the second sorting trolley and the blanking chute.

[0019] As described above, the anti-falling part feeding and bagging device and the sorting system involved in the present utility model have the following beneficial effects:

[0020] In this application, by using a pair of support rollers to support the upper end of the conveyor belt, the conveyor belt has a conveying plane for horizontally conveying the sorted objects forward; in particular, the support rollers are small-diameter rollers with a diameter not greater than 40 mm. In this way, the size of the triangular-like area formed between two adjacent sets of conveying components can be greatly reduced, making the connection between two adjacent sets of conveying components smoother, effectively preventing the smaller sorted objects from getting stuck in the triangular-like area, ensuring that the sorted objects conveyed forward by the latter set of conveying components can smoothly transition to the former set of conveying components, greatly reducing the probability of part dropping, and ultimately ensuring the reliability and accuracy of the sorting of the sorted objects.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

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

[0058] This application relates to the field of logistics, and particularly to an anti-drop-off feeding device for automatically sorting objects and a sorting system including the anti-drop-off feeding device.

[0059] As Figure 1 shown, the anti-drop-off feeding device involved in this application includes a feeding rack 10 provided with a feeding area 101 and a plurality of sets of conveying components 20 assembled in the feeding area 101. The conveying direction of the conveying components 20 is the conveying direction of the anti-drop-off feeding device. For the convenience of description, in the following embodiments, the conveying direction in which the conveying components 20 convey the objects to be sorted is defined as the forward direction. The plurality of sets of conveying components 20 are arranged in sequence along their conveying direction. The number of the conveying components 20 assembled in a single feeding area 101 is determined according to actual needs and may be two sets, three sets, or more sets; Figure 1 In the shown embodiment, two sets of conveying components 20 are assembled in a single feeding area 101.

[0060] As Figures 2 to 5 shown, on the left and right sides of the feeding area 101 of the feeding rack 10, there are fixedly installed rack side plates 102, and the rack side plates 102 are part of the feeding rack 10. Each set of conveying components 20 includes a conveying driving source 21, a pair of support rollers 22 arranged side by side in sequence along their conveying direction, and a conveying belt 23 connected to the outer circumferences of the pair of support rollers 22. The arrangement heights of the pair of support rollers 22 are the same, so that the conveying belt 23 has a conveying plane connected to the upper ends of the pair of support rollers 22; the left and right ends of the support rollers 22 are rotatably supported in the rack side plates 102 of the feeding rack 10 and are in transmission connection with the conveying driving source 21. A triangular-like area 30 is formed between two adjacent sets of conveying components 20 in sequence. The support rollers 22 are small-diameter rollers with a diameter not greater than 40 mm, that is, the support rollers 22 are rollers with an unconventional outer diameter size, but rather small-diameter rollers far smaller than the unconventional outer diameter size.

[0061] In the anti-drop part feeding device involved in the present application, when the conveying drive source 21 operates, a pair of support rollers 22 rotate. At the same time, the conveying belt 23 makes a rotary motion. The sorting personnel place a plurality of sorted objects to be sorted on the conveying plane of the conveying belt 23 of the last set of conveying components 20 at the rear side of the anti-drop part feeding device, and the conveying belt 23 of this set of conveying components 20 conveys the sorted objects forward. In particular, in the present application, the support rollers 22 adopt small-diameter rollers with a diameter not greater than 40 mm. In this way, the size of the triangular-like area 30 formed between two adjacent sets of conveying components 20 before and after can be significantly reduced, making the connection between two adjacent sets of conveying components 20 before and after smoother, effectively preventing the sorted objects with a smaller volume from getting stuck in the triangular-like area 30, ensuring that the sorted objects conveyed forward by the latter set of conveying components 20 can smoothly transition to the former set of conveying components 20, greatly reducing the probability of dropping parts, and finally ensuring the reliability and accuracy of sorting the sorted objects. Finally, after the sorted objects are conveyed forward by the conveying belts 23 of multiple sets of conveying components 20, they are conveyed to the front end of the anti-drop part feeding device; then, they are caught by the sorting mechanism in the sorting system. Therefore, the rear end of the anti-drop part feeding device is its sorted object feeding end, and the front end of the anti-drop part feeding device is its sorted object discharging end.

[0062] In addition, multiple sets of conveying components 20 each adopt an independent conveying drive source 21, so that the conveying speeds of the conveying belts 23 of each set of conveying components 20 are independently controlled, thereby enabling better control of the buffering of the sorted objects on multiple sets of conveying components 20, avoiding excessive accumulation of the sorted objects at the front end of the anti-drop part feeding device, and thus improving the equipment efficiency.

[0063] Preferably, in the present application, the diameter of the support rollers 22 is 28 - 32 mm, which can not only effectively prevent the sorted objects with a smaller volume from getting stuck in the triangular-like area 30, but also ensure good supporting performance for the conveying belt 23.

[0064] Furthermore, based on the structure that the support rollers 22 adopt small-diameter rollers, it is inevitable to reduce the contact area between the support rollers 22 and the conveying belt 23, and thus inevitably reduce the friction force between the support rollers 22 and the conveying belt 23; if the structure that the conveying drive source 21 drives the support rollers 22 to rotate to drive the conveying belt 23 to rotate is adopted, there will be a defect that the rotation speed of the conveying belt 23 cannot meet the requirements. Therefore, the drive structure in which the conveying drive source 21 drives the conveying belt 23 to rotate in the present application is preferably: as Figures 2 to 5As shown, the conveying drive source 21 is a motor. Each set of conveying components 20 further includes a driving roller 24, a first pulley 25 fixed on the motor shaft of the conveying drive source 21, a second pulley 26 fixed on the driving roller 24, and a synchronous belt 27 connected between the first pulley 25 and the second pulley 26. The driving roller 24 is parallel to the supporting roller 22, and the left and right ends of the driving roller 24 are rotatably supported in the frame side plate 102 of the bag supply frame 10; if the driving roller 24 is a roller with an unconventional outer diameter size, the diameter of the driving roller 24 is greater than the diameter of the supporting roller 22. Preferably, the diameter of the driving roller 24 is 3 - 5 times greater than the diameter of the supporting roller 22; the driving roller 24 is in contact and cooperation with the inner peripheral surface of the conveying belt 23 and is distributed on the lower side of a pair of supporting rollers 22. In this way, the conveying drive source 21 drives the driving roller 24 to rotate through the first pulley 25, the second pulley 26, and the synchronous belt 27. There is a large contact area and large frictional force between the driving roller 24 and the conveying belt 23. The driving roller 24 drives the conveying belt 23 to perform a rotary motion, which not only improves the reliability of the rotary motion of the conveying belt 23, ensures that it accurately conveys the sorted objects forward, but also can ensure that the rotation speed of the conveying belt 23 meets the design requirements.

[0065] Further, as Figure 2 and Figure 4 shown, a motor installation area 28 is formed on the outer peripheral side of the conveying belt 23 between one of the pair of supporting rollers 22 and the driving roller 24. The conveying drive source 21 is located in the motor installation area 28 and fixed to the frame side plate 102 of the bag supply frame 10, which facilitates the installation of the conveying drive source 21 and makes the overall structure more compact, reducing the overall occupied space of the anti-drop bag supply device.

[0066] Further, as Figures 2 to 4As shown, each conveying assembly 20 further includes a tension adjusting roller 29 and a tension adjusting assembly. The tension adjusting roller 29 is arranged in the motor installation area 28; the tension adjusting roller is parallel to the driving roller 24. The tension adjusting roller 29 includes a roller shaft portion 291 and a tensioning cylinder portion 292 rotatably assembled on the roller shaft portion 291. The tensioning cylinder portion 292 is in contact and cooperation with the outer peripheral surface of the conveying belt 23. The roller shaft portion 291 is movably installed on the bag supply rack 10 in the front and rear directions through the tension adjusting assembly. In this way, by adjusting the front and rear positions of the roller shaft portion 291 through the tension adjusting assembly, the front and rear positions of the tension adjusting roller 29 are adjusted, and further the tension degree of the conveying belt 23 is adjusted. Preferably, the tension adjusting assembly can adopt a bolt and nut structure: the tension adjusting assembly includes an adjusting seat 210 fixed to the bag supply rack 10, an adjusting groove 211 opened in the bag supply rack 10 and extending in the front and rear directions, an adjusting bolt extending in the front and rear directions, and a locking nut connected to the adjusting bolt. The adjusting bolt and the locking nut are not shown in the figure. The roller shaft portion 291 is movably inserted into the adjusting groove 211. The adjusting bolt is inserted into the roller shaft portion 291 and the adjusting seat 210, and the locking nut abuts against the outer peripheral side of the roller shaft portion 291.

[0067] Furthermore, as Figure 2 and Figure 4 shown, at least one circumferentially extending limiting rib 231 is provided on the outer peripheral surface of the conveying belt 23; when there are several limiting ribs 231, the several limiting ribs 231 are arranged side by side left and right in a direction perpendicular to the conveying direction of the conveying assembly 20. The limiting rib 231 limits the sorted objects conveyed forward on the conveying belt 23 in the left and right directions, improving the accuracy of conveying the sorted objects forward. The number of the limiting ribs 231 on each conveying belt 23 is determined according to actual requirements. In this embodiment, there are two limiting ribs 231 on the left and right.

[0068] Furthermore, as Figure 1 shown, there are several bag supply areas 101 in the bag supply rack 10. The several bag supply areas 101 are arranged side by side left and right in a direction perpendicular to the conveying direction of the conveying assembly 20, and several groups of conveying assemblies 20 are assembled in each bag supply area 101. Figure 1 In the shown embodiment, there are two bag supply areas 101 on the left and right in the bag supply rack 10, and two groups of conveying assemblies 20 are assembled in each bag supply area 101. After such setting, the bag supply efficiency of the sorted objects can be improved, and finally the sorting efficiency of the sorting system can be improved.

[0069] Furthermore, as Figure 5As shown, along the conveying direction of the conveying assembly 20 for forwardly conveying the objects to be sorted, multiple groups of conveying assemblies 20 are distributed in a stepped manner from back to front and from high to low, that is, the conveying assembly 20 arranged at the rear side is higher than the conveying assembly 20 arranged at the front side. In this way, after the front and rear adjacent two groups of conveying assemblies 20 adopt a structure with high and low dislocation, the gap between the adjacent two groups of conveying assemblies 20 can be better reduced, the triangular-like area 30 can be made smaller, and the prevention of object dropping can be better realized. At the same time, after adopting multiple groups of conveying assemblies 20 front and back, the formation of a groove in the middle part of the conveying belt 23 can be avoided, thereby avoiding the bad phenomenon that light objects to be sorted jump on the conveying belt 23 and ensuring the reliability of feeding.

[0070] Furthermore, the present utility model further provides a sorting system. As Figure 6 shown, the sorting system includes a fixed frame 40 provided with a feeding and bagging station 41, a sorting mechanism installed on the fixed frame 40, several blanking chutes 50 all installed on the fixed frame 40, a receiving mechanism 60 arranged on the outer side of the fixed frame 40, and the above-mentioned anti-drop feeding and bagging device. The anti-drop feeding and bagging device is installed at the feeding and bagging station 41 of the fixed frame 40. The sorting mechanism is connected between the anti-drop feeding and bagging device and the blanking chute 50. The receiving mechanism 60 has a plurality of receiving frames 61 corresponding to the blanking chutes 50 one by one. Both the blanking chute 50 and the receiving frame 61 are of a multi-layer structure up and down. When the anti-drop feeding and bagging device conveys the objects to be sorted forward to the front end of the anti-drop feeding and bagging device, the objects to be sorted fall onto the sorting mechanism, and then the sorting mechanism conveys the objects to be sorted to the corresponding target blanking chute 50, and then the objects to be sorted slide down through the blanking chute 50 into the corresponding receiving frame 61, realizing the automatic sorting of the objects to be sorted.

[0071] Furthermore, the sorting system involved in the present application can be an end feeding and bagging structure or an intermediate feeding and bagging structure.

[0072] When the sorting system adopts end feeding and bagging, the length direction of the fixed frame 40 is consistent with the conveying direction of the anti-drop feeding and bagging device, both being the front-back direction. The anti-drop feeding and bagging device is arranged at the front end or the rear end of the fixed frame 40 along the length direction of the fixed frame "40". At this time, in the length direction of the fixed frame 40, the sorting system is only provided with the blanking chute 50 and the receiving mechanism 60 on one side of the anti-drop feeding and bagging device.

[0073] When the sorting system adopts intermediate feeding and bagging, as Figure 6As shown in the figure, the length direction of the fixed frame 40 is perpendicular to the conveying direction of the anti-falling part bag feeding device. Therefore, the length direction of the fixed frame 40 is the left-right direction. The anti-falling part bag feeding device is arranged at the middle position of the fixed frame 40 along the length direction of the fixed frame 40. The fixed frame 40 is provided with blanking chutes 50 and receiving mechanisms 60 on both the left and right sides of the anti-falling part bag feeding device. The sorting system is provided with blanking chutes 50 and receiving mechanisms 60 on both the left and right sides of the anti-falling part bag feeding device.

[0074] Compared with the sorting system for end bag feeding, the sorting system for middle bag feeding has higher sorting efficiency.

[0075] Furthermore, in the sorting system involved in the present application, the sorting mechanism preferably adopts the following two embodiments.

[0076] Sorting system Embodiment 1: The sorting mechanism includes a moving frame movably installed on the fixed frame 40 along the length direction of the fixed frame 40, and a first sorting trolley liftably installed on the moving frame. The moving frame can reciprocate between the anti-falling part bag feeding device and the blanking chute 50. The moving frame drives the first sorting trolley and the sorted objects thereon to move along the length direction of the fixed frame 40 to the target position, and then the first sorting trolley moves up and down to the target layer.

[0077] Sorting system Embodiment 2: As Figure 6 shown in the figure, the sorting mechanism includes a second sorting trolley 70 liftably installed on the fixed frame 40, and several third sorting trolleys 80 arranged vertically. The second sorting trolley 70 can reciprocate between the anti-falling part bag feeding device and several third sorting trolleys 80. The several third sorting trolleys 80 correspond one by one to the layers of the blanking chute 50. The several third sorting trolleys 80 are all movably installed on the fixed frame 40 along the length direction of the fixed frame 40 and can reciprocate between the second sorting trolley 70 and the blanking chute 50. The second sorting trolley 70 drives the sorted objects thereon to move up and down to the target layer, and then transfers the sorted objects to the third sorting trolley 80 on this layer. The third sorting trolley 80 drives the sorted objects thereon to move along the length direction of the fixed frame 40 to the target position.

[0078] In summary, the utility model effectively overcomes various disadvantages in the prior art and has high industrial utilization value.

[0079] The above embodiments are only illustrative of the principles and effects of the present utility model and are not intended to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
