Each sorting trolley needs to be equipped with an electric roller drive device to realize the sorting function, and the energy consumption of the sorting process is relatively large. Summary of the invention

[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field based on the present application belong to the scope of protection of the present application.

[0035] like Figure 1-Figure 3 As shown, an embodiment of the present application proposes a sorting device. The sorting device includes a sorting trolley 100 and a guide rail system. Specifically, the sorting trolley 100 includes a trolley plate 110, a guide member 120 and a push assembly 130. The trolley plate 110 is used to place items to be sorted. The trolley plate 110 has a first direction and a second direction perpendicular to the first direction. The guide member 120 is disposed on the trolley plate 110 and extends along the first direction. The push assembly 130 is slidably connected to the guide member 120. The push assembly 130 is used to push the items to be sorted so as to push the items to be sorted out of the trolley plate 110. The guide rail system includes a plurality of guide rail units 200 connected to each other, the guide rail unit 200 includes a frame 210, a guide rail 220, a limit assembly 230 and an adjustment assembly 240, the guide rail 220 is arranged on the frame 210, the sorting trolley 100 is arranged on the guide rail 220 in a manner that it can move along the second direction, the limit assembly 230 includes a limit member, and the limit member is provided with a driving surface, the driving surface is inclined relative to the first direction, and the driving surface is configured to drive the push assembly 130 to slide along the guide member 120 during the movement of the sorting trolley 100 along the second direction, and the adjustment assembly 240 is arranged at the end of the driving surface, and is used to touch the push assembly 130 so that the push assembly 130 contacts the driving surface.

[0036] It should be noted that the trolley board 110 has a first direction and a second direction, and in the same horizontal plane, the second direction is perpendicular to the first direction. The first direction is the length direction or width direction of the trolley board 110. When the first direction is the length direction of the trolley board 110, the second direction is the width direction of the trolley board 110; when the first direction is the width direction of the trolley board 110, the second direction is the length direction of the trolley board 110. The "first direction" and "second direction" involved in this application are understood in this way.

[0037] The sorting device of the embodiment of the present application has the following working process: the items to be sorted are placed on the trolley plate 110, and the sorting trolley 100 moves along the guide rail 220. At this time, the push assembly 130 is located on one side of the trolley plate 110. When the sorting trolley 100 reaches the specified sorting position, the adjustment assembly 240 actuates to trigger the push assembly 130 so that the push assembly 130 slides a certain distance along the guide member 120 and contacts the driving surface of the limit member. The driving surface is inclined relative to the first direction. At this time, the sorting trolley 100 drives the push assembly 1 30 moves along the second direction, and the driving surface has a limiting effect on the movement of the pushing assembly 130 along the second direction, and at the same time makes the pushing assembly 130 have a tendency to move in the first direction, so that the pushing assembly 130 slides along the guide member 120 during the movement of the sorting trolley 100 along the second direction, so that the pushing assembly 130 moves from one side of the trolley plate 110 to the other side. During this process, the pushing assembly 130 pushes the to-be-sorted pieces to move on the trolley plate 110, and pushes the to-be-sorted pieces out of the trolley plate 110 to complete the sorting. It can be seen from the above process that, based on the sorting equipment of the embodiment of the present application, the adjustment component 240 only needs to provide a small displacement for the pushing component 130, and the sorting can be completed without fully participating in the movement of the pushing component 130 along the guide member 120. Compared with the sorting equipment in the related art that uses an electric roller to drive the belt of the sorting trolley 100 to rotate, thereby sorting and sending out the items to be sorted, the sorting equipment of the embodiment of the present application reduces the energy consumption of the movement of a single sorting trolley 100, thereby reducing the energy consumption of the entire sorting process.

[0038] like Figure 1 As shown, in some embodiments of the present application, flange structures 111 extending along the first direction are provided at both ends of the trolley plate 110 to prevent the items to be sorted from falling off the trolley plate 110 .

[0039] like Figure 1 , Figure 2 As shown, in some embodiments of the present application, a trolley pulley 150 may be provided on the trolley plate 110, and the trolley pulley 150 rolls along the guide rail 220 to drive the sorting trolley 100 to move. Compared with sliding friction, rolling friction is smaller, which is conducive to the movement of the sorting trolley 100.

[0040] like Figure 3-Figure 5As shown, in some embodiments of the present application, the adjustment component 240 includes a toggle member 241 and a first driving device 242, the first end of the toggle member 241 is rotatably connected to the frame 210, the first driving device 242 is used to drive the toggle member 241 to rotate around its first end, and the second end of the toggle member 241 is used to toggle the pushing component 130 of the sorting cart 100 so that the pushing component 130 contacts the driving surface of the limit member. When the sorting trolley 100 has not reached the sorting position, the push assembly 130 does not need to move, and the push assembly 130 passes through the outside of the toggle member 241; when the sorting trolley 100 reaches the designated sorting position, the first drive device 242 drives the toggle member 241 to rotate around its first end, and the second end of the toggle member 241 contacts the push assembly 130 during the rotation process and toggle the push assembly 130 to change its motion state, providing the push assembly 130 with an initial velocity for sliding along the guide member 120, so that the push assembly 130 slides a certain distance along the guide member 120 and contacts the driving surface of the limiter, preparing for the subsequent movement of the push assembly 130 along the driving surface. It can be seen from the above process that the first drive device 242 drives the toggle member 241 to rotate, and the toggle member 241 toggle the push assembly 130 during the rotation process so that it obtains the initial velocity of moving along the second direction. The driving method is simple, the first drive device 242 provides power for a short time, and the energy consumption is low.

[0041] Furthermore, the number and position of the adjustment components 240 can be set according to actual conditions. For example, when the sorting trolley 100 can only move in one direction along the guide rail 220, there can be one adjustment component 240 and it can be set at one end of the driving surface, so as to realize the control of the push component 130 during the trolley's single-line movement. When the sorting trolley 100 can move in two directions along the guide rail 220, there can be two adjustment components 240 and they can be set at both ends of the driving surface, one of which can be used to control the push component 130 when the sorting trolley 100 moves in a certain direction, and the other adjustment component 240 can be used to control the push component 130 when the sorting trolley 100 moves in the opposite direction.

[0042] like Figure 5As shown, in some embodiments of the present application, the first driving device 242 includes a first electromagnet 2424, a first rocker arm 2425, a first rotating shaft 2421, a bearing seat 2422 and a deep groove ball bearing 2423. A through hole is provided on the frame 210, and a bearing seat 2422 is installed in the through hole. The deep groove ball bearing 2423 is installed in the bearing seat 2422. The first rotating shaft 2421 passes through the deep groove ball bearing 2423. The upper end of the first rotating shaft 2421 is connected to the first end of the toggle member 241, and the lower end is connected to the first rocker arm 2425. The first rocker arm 2425 is also connected to the first electromagnet 2424. The first electromagnet 2424 drives the first rotating shaft 2421 to rotate through the first rocker arm 2425, and the first rotating shaft 2421 drives the toggle member 241 to rotate. The deep groove ball bearing 2423 has the advantages of low friction and high rotation speed, which can make the first rotating shaft 2421 rotate more flexibly, and further make the toggle member 241 rotate more flexibly.

[0043] like Figure 6-Figure 8 As shown, in some embodiments of the present application, the limit assembly 230 includes two first limit members 231 and two second limit members 232, the two first limit members 231 are in a collinear relationship and are spaced apart, the two second limit members 232 are in a collinear relationship and are spaced apart, the first limit members 231 and the second limit members 232 are not in a collinear relationship and are not parallel, the limit assembly 230 also includes a distribution member 233 and a second driving device 234, the distribution member 233 is arranged at the interval between the two first limit members 231 and at the interval between the two second limit members 232, the distribution member 233 is rotatably connected to the frame 210, the second driving device 234 is used to drive the distribution member 233 to rotate, and a distribution surface 2331 is provided on the distribution member 233, and the distribution surface 2331 is used to connect the driving surfaces on the two first limit members 231 or the driving surfaces on the two second limit members 232. The above setting method can obtain a first driving surface composed of the driving surface on the two first limit members 231 and the distribution surface 2331 or a second driving surface composed of the driving surface on the two second limit members 232 and the distribution surface 2331. The first driving surface and the second driving surface are cross-set, which can realize the reciprocating movement of the push assembly 130 along the guide member 120 in the first direction. Specifically, when the push assembly 130 contacts the first driving surface, it can realize unidirectional movement in one direction under the action of the first driving surface. When the push assembly 130 contacts the second driving surface, it can realize unidirectional movement in the opposite direction to the aforementioned direction under the action of the second driving surface. The switching between the first driving surface and the second driving surface can be completed by rotating the distribution member 233, which improves the sorting flexibility of the sorting equipment; at the same time, sorting positions can be set on both sides of the sorting trolley 100, which is conducive to improving the sorting efficiency.

[0044] The working principle of the limiter assembly 230 is as follows: first, the limiter to be selected is determined according to the moving direction of the push assembly 130, and then the second driving device 234 drives the distribution member 233 to rotate until the distribution surface 2331 is flush with the driving surface on the selected limiter, forming a complete first driving surface or a second driving surface, and preparing for the subsequent movement of the push assembly 130. When the first limiter 231 is selected, the push assembly 130 moves along the first driving surface and passes through the gap between the second limiters 232; when the second limiter 232 is selected, the push assembly 130 moves along the second driving surface and passes through the gap between the first limiters 231.

[0045] like Figure 8 As shown, in some embodiments of the present application, the second driving device 234 includes a second electromagnet 2342, a second swing rod 2343 and a second rotating shaft 2341. The frame 210 is provided with a through hole. The distribution member 233 is connected to the upper end of the second rotating shaft 2341 through the through hole. The lower end of the second rotating shaft 2341 is connected to the second swing rod 2343. The second swing rod 2343 is connected to the second electromagnet 2342. The second electromagnet 2342 drives the second rotating shaft 2341 to rotate through the second swing rod 2343, and the second rotating shaft 2341 drives the distribution member 233 to rotate. The second swing rod 2343 converts the linear motion of the second electromagnet 2342 into the rotation of the second rotating shaft 2341.

[0046] like Figure 6 , Figure 7 As shown, in some embodiments of the present application, the limiting assembly 230 also includes a distribution member limiting member 235, which is arranged between the distribution member 233 and the frame 210, and a limiting structure for limiting the rotation angle of the distribution member 233 is provided on the distribution member limiting member 235. The distribution member 233 rotates under the drive of the second drive device, and the accuracy of the rotation angle may not be high. The distribution member limiting member 235 with a limiting structure is provided, so that the distribution member 233 can stop rotating when it reaches the set position, so that the distribution surface 2331 can be flush with the driving surface on the limiting member, avoiding the occurrence of uneven connection of the driving surface due to insufficient rotation angle accuracy, and facilitating the movement of the push assembly 130 along the driving surface. Specifically, the limiting structure can be a limiting column 2351, and the distribution member 233 stops moving after rotating to contact with the limiting column 2351.

[0047] like Figure 4As shown, in some embodiments of the present application, the adjustment assembly 240 further includes a toggle member stopper 243, which is mounted on the frame 210, located outside the toggle member 241, and spaced apart from the toggle member 241. The toggle member stopper 243 limits the rotation angle of the toggle member 241, and can prevent the toggle member 241 from rotating too much, causing the toggle member 241 and the push assembly 130 to have too small a contact area, thereby causing the toggle member 241 to be unable to toggle the push assembly 130. When the push assembly 130 does not need to move, the push assembly 130 passes through the gap between the toggle member 241 and the toggle member stopper 243.

[0048] like Figure 1 , Figure 2 As shown, in some embodiments of the present application, the pushing assembly 130 of the sorting trolley 100 includes a sliding member 131 and a pushing member 132, the sliding member 131 extends along the second direction, the sliding member 131 is slidably connected to the guide member 120, the pushing member 132 is arranged above the trolley plate 110, and is used to push the items to be sorted, and the pushing member 132 is fixedly connected to the sliding member 131. During the sorting process, the sliding member 131 slides along the guide member 120, and the sliding member 131 drives the pushing member 132 fixedly connected thereto to move, and the pushing member 132 pushes the items to be sorted to move on the trolley plate 110, and pushes the items to be sorted out of the trolley plate 110.

[0049] like Figure 1 , Figure 2 As shown, in some embodiments of the present application, the guide member 120 may be a cylindrical guide rod, both ends of which are fixedly connected to the trolley plate 110, a linear bearing 133 is provided inside the sliding member 131, and the guide rod passes through the inside of the linear bearing 133. The linear bearing 133 can improve the guiding accuracy of the guide rod and make the sliding between the guide rod and the sliding member 131 smoother.

[0050] like Figure 1 , Figure 2 As shown, in some embodiments of the present application, the push member 132 includes a push plate 1321 and a connecting plate 1322. The push plate 1321 is arranged above the trolley plate 110 to push the items to be sorted. The connecting plates 1322 are arranged at both ends of the sliding member 131. The connecting plates 1322 are respectively connected to the sliding member 131 and the push plate 1321 by fasteners. The push assembly 130 moves on the trolley plate 110 for a long time and pushes the items to be sorted, which is prone to wear. When the wear reaches a certain degree, the push assembly 130 needs to be replaced. The push member 132 is divided into two parts, the push plate 1321 and the connecting plate 1322. When repairing, only part of the structure of the push member 132 only needs to be replaced, which can save costs compared to the overall replacement. In addition, the connecting plate 1322 is fixedly connected to the push plate 1321 and the sliding member 131 by fasteners, and the connection is reliable and easy to disassemble and assemble.

[0051] like Figure 1 , Figure 2 As shown, in some embodiments of the present application, the push assembly 130 further includes a push plate pulley 1323, which is disposed at both ends of the sliding member 131 and configured to roll along the lower surface of the trolley plate 110. This is equivalent to limiting both ends of the sliding member 131 by the trolley plate 110 in the vertical direction, which can prevent the sliding member 131 from rotating around the guide member 120, so that the push assembly 130 can slide along the guide member 120 more smoothly.

[0052] like Figure 1 , Figure 2 As shown, in some embodiments of the present application, the push assembly 130 of the sorting trolley 100 includes a rolling member 140, and the rolling member 140 is configured to roll along the driving surface of the limiter. The rolling member 140 rolls along the driving surface, driving the push assembly 130 to move, which can reduce the friction between the push assembly 130 and the driving surface, so that the movement of the push assembly 130 along the driving surface is smoother. Specifically, the rolling member 140 can be a roller arranged laterally, or a spherical member or other rolling member 140 that can provide rolling motion, and the present application does not limit this.

[0053] like Figure 3 As shown, in some embodiments of the present application, the frame 210 includes a frame 211, a first support plate 212, a second support plate 213 and a support connector 214, the support connector 214 is fixed to the frame 211, the first support plate 212 and the second support plate 213 are fixed to the support connector 214, the adjustment assembly 240 is installed on the first support plate 212, the distribution member 233 is installed on the second support plate 213, and the limit member is respectively connected to the first support plate 212 and the second support plate 213 through fasteners. If the distribution member 233, the adjustment assembly 240 and the limit member are directly fixed to the frame 211, many connection holes for installation need to be opened on the frame 211, which will cause the rigidity of the frame 211 to decrease. The above structure is installed on the support plate, and then the support plate and the frame 211 are fixed by the support connector 214. The support connector 214 connects the first support plate 212, the second support plate 213 and the frame 211 into a whole, which is beneficial to improve the rigidity and stability of the frame 210 and helps to reduce shock. The adjustment assembly 240 and the distribution member 233 are respectively arranged on the first support plate 212 and the second support plate 213. Compared with using a whole support plate, the separate design is convenient for replacement.

[0054] Furthermore, the supporting connector 214 may be an aluminum profile, which has the advantages of low density and high strength, and can enhance the stability of the frame 210 and help control the quality of the frame 210 .

[0055] like Figure 3As shown, in some embodiments of the present application, the first support plate 212 and the second support plate 213 are alternately arranged along the second direction. The sorting positions corresponding to the sorting device arranged in this way are the most dense, which is conducive to reducing the volume of the sorting device and improving the sorting efficiency of the sorting device.

[0056] In some embodiments of the present application, the guide rail 220 is a straight guide rail or a curved guide rail. The guide rails 220 in the guide rail unit 200 are connected to each other. The straight guide rails can be arranged in parallel up and down, and the curved guide rails connect the straight guide rails arranged up and down together to form an upper and lower spatial circular track. When the sorting trolley 100 completes sorting, it returns to the loading point from the lower guide rail 220, reloads the items to be sorted, and prepares to enter the next round of sorting, which can reduce the volume of the sorting equipment and save space; the straight guide rails can also be set on the same horizontal plane, and the curved guide rails connect the straight guide rails together to form a horizontal circular track. Compared with the use of a linear track, the structure of the circular track is more compact and occupies less space.
