[0040] Please refer to Figures 1-4 The embodiments of the application provide a sorting device 10, which comprises a rack 120, a track 121, a plurality of sorting trolleys 11, and a reversing mechanism 130, wherein the track 121 and the reversing mechanism 130 are arranged on the rack 120, and the plurality of sorting trolleys 11 move along the track 121. Specifically, the rack 120 is used to support the sorting trolleys 11 and the reversing mechanism 130, and the structure of the rack 120 is not limited, for example, the rack 120 can adopt a frame structure. Specifically, please refer to Figures 2 to 5 As shown in the figure, the rack 120 is provided with the track 121, the track 121 is arranged above the rack 120, and the form of the track 121 is not limited. In this embodiment, the track 121 comprises two guide rails which are parallel and spaced apart, and the length of the guide rail can be set as needed. The two sides of the track 121 are respectively provided with a drop pocket, and the drop pocket can be provided with a container for holding sorted articles or a device for transferring articles, etc.

[0041] The sorting trolley 11 needs to be used in cooperation with the reversing mechanism 130, and is used for sorting articles so that the articles enter the specified drop pocket. The structure of the sorting trolley 11 can adopt but is not limited to the following scheme: please refer to Figure 6 As shown in the figure, the sorting trolley 11 comprises a base 110, a conveying belt 111 and a sorting driving member arranged on the base 110, two rollers are arranged on the base 110 at intervals, the conveying belt 111 is supported by the two rollers, the conveying belt 111 can support articles, and the conveying belt 111 is fixedly connected or drivingly connected with the sorting driving member. Under the driving of the sorting driving member, the conveying belt 111 can convey the articles to the specified drop pocket; when the sorting trolley 11 moves, the sorting driving member is configured to cooperate with the reversing mechanism 130 and is guided by the reversing mechanism 130 to move in different directions, so that the conveying belt 111 of the sorting trolley 11 can convey the articles in different directions.

[0042] In an embodiment, the sorting transmission member comprises a driving rod, and the driving rod is fixedly connected with the conveying belt 111. When the reversing mechanism 130 guides the driving rod to move in different directions, the driving rod drives the conveying belt 111 fixedly connected therewith to convey the articles in different directions.

[0043] In the embodiment, the sorting transmission member comprises an input wheel 112, and the conveying belt 111 is in transmission connection with the input wheel 112. Specifically, the position of the input wheel 112 on the base 110 can move along the conveying direction of the conveying belt 111, and the input wheel 112 can rotate. When the sorting trolley 11 moves, the input wheel 112 is configured to cooperate with the reversing mechanism 130 and is guided by the reversing mechanism 130 to move in different directions. Meanwhile, the input wheel 112 can be driven to rotate by the reversing mechanism 130. The input wheel 112 moves in different directions, and the rotating direction is different. The rotating direction of the input wheel 112 is different, and the conveying direction of the conveying belt 111 is different.

[0044] The reversing mechanism 130 and the two drop openings located on both sides of the track 121 constitute a drop opening unit. The sorting device 10 comprises one or more drop opening units. In the embodiment, a plurality of drop opening units are arranged on the rack 120 in the extension direction of the track 121. According to specific needs, several or even dozens of drop opening units can be arranged.

[0045] Each drop opening unit has two drop openings, wherein the two drop openings are respectively a first drop opening and a second drop opening. The first drop opening is located on one side of the track 121, and the second drop opening is located on the other side of the track 121. The two drop openings can sort two different kinds of articles. By arranging a plurality of drop opening units in sequence, more kinds of articles can be sorted, and the sorting efficiency is higher.

[0046] The sorting trolley 11 is supported on the track 121 and can move along the track 121. In the embodiment, the sorting trolley 11 is driven by a power mechanism 123. The power mechanism 123 is configured to drive the sorting trolley 11 to move along the track 121. The power mechanism 123 includes a power motor 124, two chain transmission assemblies 125 and two transmission shafts 126. The power motor 124 is fixed to the rack 120 and configured to drive the chain transmission assemblies 125 to work. The chain transmission assemblies 125 extend along the direction of the track 121 and are arranged in parallel and spaced apart on the rack 120 in the conveying direction of the conveying belt 111. Each chain transmission assembly 125 includes a driving sprocket, a driven sprocket and a transmission chain. The driving sprocket and the driven sprocket are arranged in parallel and spaced apart in the extension direction of the track 121, and the transmission chain is sleeved on the driving sprocket and the driven sprocket. One of the two transmission shafts 126 is coaxially fixed with the driving sprockets of the two chain transmission assemblies 125, and the other of the two transmission shafts 126 is coaxially fixed with the driven sprockets of the two chain transmission assemblies 125. The power motor 124 is in transmission connection with one of the two driving sprockets or the transmission shaft 126 connecting the two driving sprockets. Each sorting trolley 11 is fixedly connected with the transmission chains of the two chain transmission assemblies 125. The plurality of sorting trolleys 11 are arranged in sequence in the extension direction of the transmission chains. When the power motor 124 works, it can drive the driving sprocket, the driven sprocket, the transmission chain and the transmission shaft 126 to rotate, thereby driving the plurality of sorting trolleys 11 to move along the track 121.

[0047] In the embodiment, the number of sorting trolleys 11 can be set to hundreds according to specific requirements, and the number of drop package units can be set to several or even dozens according to specific requirements. Moreover, each drop package unit includes a reversing mechanism 130. Therefore, the number of reversing mechanisms 130 is much smaller than the number of sorting trolleys 11. Each reversing mechanism 130 can be configured to drive the sorting transmission members of the plurality of sorting trolleys 11 to move in different directions in sequence, thereby driving the conveying belts 111 of the plurality of sorting trolleys 11 to convey the articles to different drop package openings in sequence. Therefore, it is not necessary to arrange a motor on each of the hundreds of sorting trolleys 11. Thus, the sorting device 10 has a simple and reliable structure and is low in cost.

[0048] As shown in Figure 7 , Figure 10 , Figure 11 In the embodiment, the reversing mechanism 130 includes a base frame 131 and a guide assembly 132. The base frame 131 is fixedly connected with the rack 120 or can be integrally formed with the rack 120. The guide assembly 132 includes a driving member 133, a connecting rod 136 and a guide member 134. The guide member 134 includes two guide plates. Specifically, the driving member 133 can be a motor or an electromagnet.

[0049] The guide plate adopts a plate-like structure. The two guide plates are respectively pivotally connected to the base frame 131. The two guide plates are arranged opposite to each other, and a guide channel 140 is formed between the two guide plates. Each guide plate can be rotatably set on the base frame 131. The two guide plates are connected by a connecting rod 136, that is, the two ends of the connecting rod 136 are respectively hinged to the two guide plates. A parallel four-bar linkage mechanism is formed between the base frame 131, the connecting rod 136 and the two guide plates, and the driving member 133 is transmission-connected to one of the guide plates.

[0050] This arrangement enables the two guide plates to rotate synchronously, thereby reducing the load of the driving member 133 and ensuring the smooth movement of the guide assembly 132. Under the drive of the driving member 133, the guide member 134 has an intermediate position (see Figure 3 and Figure 8 As shown) and two guide positions, the two guide positions are defined as the first guide position (please refer to Figure 2 and Figure 7 shown) and the second guide position (see Figure 4 and Figure 9 As shown), as the guide plate rotates, the guide member 134 can switch between the middle position, the first guide position, and the second guide position. The guide channel 140 when the guide member 134 is in the first guide position is set at an angle to the guide channel 140 when the guide member 134 is in the second guide position. The angle can be 30 degrees, 50 degrees, 90 degrees, or 120 degrees, and can be set as needed.

[0051] Of course, in other embodiments, the guide plates may be moved on the base frame 131 in other ways. For example, the guide plates may be slidably arranged on the base frame 131, and the two guide plates may be able to translate as a whole on the base frame 131; or the two guide plates may be not parallel but distributed in a V-shape, and the entrance of the guide channel 140 may be arranged in a trumpet shape. The two guide plates may be connected as a whole by a connecting piece, and the connecting piece or one of the guide plates may be pivotally connected to the base frame 131, that is, the whole may be rotatably arranged on the base frame 131.

[0052] The two guide plates are defined as a first guide plate 144 and a second guide plate 145. In the embodiment, the first guide plate 144 and the second guide plate 145 are respectively pivoted to the base frame 131 through a pivoting shaft 147, and the first guide plate 144 and the second guide plate 145 can rotate around the respective pivoting shaft 147. Optionally, the guide assembly 132 further includes a transmission wheel 138 and a transmission rod 139. In the embodiment, the driving member 133 is a motor, the transmission wheel 138 is rotatably arranged on the base frame 131, and the transmission wheel 138 can be drivingly connected to the motor in a gear meshing manner. One end of the transmission rod 139 is eccentrically hinged to the transmission wheel 138, and the other end of the transmission rod 139 is hinged to the first guide plate 144. The base frame 131, the transmission wheel 138, the transmission rod 139, and the first guide plate 144 constitute a crank linkage mechanism. When the output shaft of the motor rotates, the transmission wheel 138 can be driven to rotate. The rotating transmission wheel 138 drives the first guide plate 144 to rotate around the pivoting shaft 147 between the first guide plate 144 and the base frame 131 through the transmission rod 139. The rotating first guide plate 144 drives the second guide plate 145 to rotate around the pivoting shaft 147 between the second guide plate 145 and the base frame 131 through the connecting rod 136, so as to switch the guide member 134 between the intermediate position, the first guide position, and the second guide position.

[0053] In the embodiment, the base frame 131 can include a fixed plate 122, the two guide plates are located on one side of the fixed plate 122, and the connecting rod 136 is located on the other side of the fixed plate 122. Each guide plate includes a first end and a second end. The first end of each guide plate is pivoted to the fixed plate 122 through a pivoting shaft 147. The second end of each guide plate can rotate around the pivoting shaft 147.

[0054] The first end of each guide plate forms an entrance of the guide channel 140, and the second end of each guide plate forms an exit of the guide channel 140. The first end of each guide plate can be rectangular, trapezoidal, or the like. In the embodiment, the first end of each guide plate is in the shape of a circular arc. The circular-arc-shaped first end can enlarge the entrance of the guide channel 140, which is beneficial to the sorting transmission member of the sorting trolley 11 entering the guide channel 140. Preferably, the first end of the guide plate is a circular arc with the pivoting shaft 147 as the center. Such an arrangement makes the position and size of the entrance of the guide channel 140 unchanged regardless of whether the guide member 134 is located at the first guide position, the second guide position, or the intermediate position, which is further beneficial to the cooperation between the guide channel 140 and the sorting transmission member of the sorting trolley 11.

[0055] The fixed plate 122 is provided with two circular arc grooves 137, and the two circular arc grooves 137 correspond to the two guide plates one by one. The center of each circular arc groove 137 is located on the pivot shaft 147 of the corresponding guide plate. The two ends of the connecting rod 136 are respectively hinged to the two guide plates through one insertion column 148. That is, the first end of the connecting rod 136 is hinged to the first guide plate 144 through one insertion column 148, and the second end of the connecting rod 136 is hinged to the second guide plate 145 through another insertion column 148. Each insertion column 148 is respectively inserted and matched with one circular arc groove 137. When the guide 134 is switched between the first guide position, the second guide position or the intermediate position, the insertion column 148 slides along the circular arc groove 137. When the guide 134 is located at the first guide position, the insertion column 148 is adjacent to the first end of the circular arc groove 137. When the guide 134 is located at the second guide position, the insertion column 148 is adjacent to the second end of the circular arc groove 137. Such an arrangement can improve the stability of the guide plate when rotating and can ensure that the guide 134 is reliably located at the first guide position or the second guide position.

[0056] In other embodiments, the two guide plates can be slidably arranged on the base frame 131, the driving member 133 is an electric motor, and the transmission rod 139, the transmission wheel 138, the transmission rod 139 and the connecting rod 136 can also be replaced by a linear transmission structure such as chain transmission or belt transmission. The electric motor drives the two guide plates to slide relative to the base frame 131 through the chain transmission structure or the belt transmission structure, so as to switch the guide 134 between the first guide position, the second guide position or the intermediate position.

[0057] Optionally, as shown in Figure 10 , Figure 11 The reversing mechanism 130 further includes a detection assembly 141. The detection assembly 141 includes a detection portion 142 and a sensor assembly 143. The detection portion 142 is arranged on the base frame 131, and the sensor assembly 143 is arranged on the transmission wheel 138. Alternatively, the detection portion 142 is arranged on the transmission wheel 138, and the sensor assembly 143 is arranged on the base frame 131. When the guide 134 is located at the first guide position, the second guide position or the intermediate position, the sensor assembly 143 outputs different combined signals.

[0058] The detection assembly 141 can timely detect the position of the guide 134, so as to confirm the direction of the conveying belt 111 of the sorting trolley 11 for conveying articles. In the present embodiment, the sensor assembly 143 is arranged on the base frame 131. The sensor assembly 143 includes a first sensor, a second sensor and a third sensor. The first sensor, the second sensor and the third sensor are sequentially arranged along the circumference of the transmission wheel 138. All of them are transmission sensors.

[0059] The detection part 142 is in a circular ring structure with a notch, and the detection part 142 is fixedly connected coaxially with the transmission wheel 138. When the guide 134 is located at the middle position, the notch of the detection part 142 is opposite to the first sensor, and the entity of the detection part 142 is matched with the second sensor and the third sensor at the same time, and the sensor assembly 143 outputs a first combined signal (such as 0, 1, 1); when the guide 134 is located at the first guide position, the notch of the detection part 142 is opposite to the second sensor, and the entity of the detection part 142 is matched with the first sensor and the third sensor at the same time, and the sensor assembly 143 outputs a second combined signal (such as 1, 0, 1); when the guide 134 is located at the second guide position, the notch of the detection part 142 is opposite to the third sensor, and the entity of the detection part 142 is matched with the first sensor and the second sensor at the same time, and the sensor assembly 143 outputs a third combined signal (such as 1, 1, 0). Therefore, the position of the guide 134 can be judged according to the combined signal output by the sensor assembly 143.

[0060] The guide channel 140 of the reversing mechanism 130 provided in the embodiment can cooperate with the sorting transmission part of the sorting trolley 11 to guide the movement of the sorting transmission part. When the guide 134 is located at the first guide position, as the sorting trolley 11 moves, the guide channel 140 can guide the sorting transmission part to move in the first direction, and the sorting transmission part moving in the first direction can make the conveying belt 111 of the sorting trolley 11 convey the articles in a set direction, so that the articles can be sent to the first drop port; when the guide 134 is located at the second guide position, as the sorting trolley 11 moves, the guide channel 140 can guide the sorting transmission part to move in the second direction, and the sorting transmission part moving in the second direction can make the conveying belt 111 of the sorting trolley 11 convey the articles in the opposite direction of the set direction, so that the articles can be sent to the second drop port. By using the reversing mechanism 130 provided in the embodiment, it is not necessary to arrange a motor on the sorting trolley 11, and by changing the position of the guide 134, the sorting transmission part can cooperate with the guide channel 140 of the guide 134, so as to drive the conveying belt 111 to convey the articles to the first drop port or the second drop port. The first direction and the second direction form an angle.

[0061] Among them, the way in which the sorting transmission member drives the conveyor belt 111 to move is not limited. In one embodiment, the sorting transmission member includes a driving rod, and the conveyor belt 111 is supported by two rollers and divided into an upward section and a downward section by the two rollers. The upward section and the downward section are arranged in parallel and spaced apart. The upward section is used to support and transport items. The sorting transmission member is fixedly connected to the downward section of the conveyor belt 111. Therefore, the sorting transmission member can move synchronously with the downward section of the conveyor belt 111 and drive the upward section of the conveyor belt 111 to move in the opposite direction. Specifically, when the sorting trolley 11 moves and the guide member 134 is in the first guiding position, the sorting transmission member enters the guide channel 140. The guide channel 140 guides the drive rod to move in the first direction, driving the upward section of the conveyor belt 111 to move in the set direction, thereby delivering items to the first package drop-off port. When the sorting trolley 11 moves and the guide member 134 is in the second guiding position, the sorting transmission member enters the guide channel 140. The guide channel 140 guides the drive rod to move in the second direction, driving the upward section of the conveyor belt 111 to move in the opposite direction of the set direction, thereby delivering items to the second package drop-off port. In this embodiment, the reversing mechanism 130 directly drives the sorting transmission member to move in different directions, thereby driving the conveyor belt 111 to transport items in different directions. Preferably, the driving rod can be provided with a roller for guidance, which is provided on the driving rod and can rotate relative to the driving rod. When the driving rod moves along the guide channel 140, the roller rolls relative to the first guide plate 144 or the second guide plate 145, thereby reducing the load of the reversing mechanism 130.

[0062] In this embodiment, the sorting transmission member includes an input wheel 112, such as Figure 2 、 Figure 7 As shown, when the guide member 134 is in the first guiding position, as the sorting trolley 11 moves, the input wheel 112 enters the guide channel 140, and the input wheel 112 is guided by the guide channel 140 to move in the first direction, and the input wheel 112 rolls along the second guide plate 145. At this time, the input wheel 112 rotates forward, driving the conveyor belt 111 to convey items in the set direction; when the guide member 134 is in the second guiding position, as shown Figure 4 、 Figure 9 As shown, as the sorting trolley 11 moves, the input wheel 112 enters the guide channel 140, and the input wheel 112 is guided by the guide channel 140 to move in the second direction, and the input wheel 112 rolls along the first guide plate 144. At this time, the input wheel 112 reverses, driving the conveyor belt 111 to transport items in the opposite direction of the set direction. Therefore, in this embodiment, the guide member 134 is located at different guiding positions to guide the input wheel 112 to move in different directions while also rotating in different directions, thereby driving the conveyor belt 111 to transport items to the first package drop-off port or the second package drop-off port.

[0063] In an embodiment, the reversing mechanism 130 further comprises two friction surfaces extending along the moving direction of the sorting trolley 11, and the two friction surfaces are located downstream of the guide 134 along the moving direction of the sorting trolley 11 and are fixed in position; the two guide positions of the input wheel 112 correspond one-to-one to the two friction surfaces, and the two friction surfaces can be defined as a first friction surface 150 and a second friction surface 151 respectively, and the first guide position corresponds to the first friction surface 150 and the second guide position corresponds to the second friction surface 151. Specifically, the guide channel 140 of the guide 134 located at the first guide position is in communication with the first friction surface 150, and as the sorting trolley 11 moves, the input wheel 112 rolls in cooperation with the first friction surface 150 after passing through the guide channel 140, the first friction surface 150 continues to drive the input wheel 112 to rotate in the forward direction to drive the conveyor belt 111 to continue to convey the articles in the set direction; the guide channel 140 of the guide 134 located at the second guide position is in communication with the second friction surface 151, and as the sorting trolley 11 moves, the input wheel 112 rolls in cooperation with the second friction surface 151 after passing through the guide channel 140, the second friction surface 151 drives the input wheel 112 to continue to rotate in the reverse direction to drive the conveyor belt 111 to continue to convey the articles in the opposite direction of the set direction. In this embodiment, by providing two fixed friction surfaces, the distance of the conveyor belt 111 conveying the articles is increased, which accordingly increases the length of the conveyor belt 111 in the conveying direction; at the same time, the length of the guide 134 can be reduced, thereby reducing the load of the driving member 133.

[0064] In an embodiment, the input wheel 112 can specifically include a driving shaft 127, a reversing wheel 128 and a pulley 129 which are sequentially sleeved on the driving shaft 127 in an axial direction, wherein the driving shaft 127 is in driving connection with the conveying belt 111, the pulley 129 is rotatably sleeved on the driving shaft 127 and is used to cooperate with the guide channel 140, and the reversing wheel 128 is fixedly sleeved on the driving shaft 127 and is used to rollingly cooperate with the first friction surface 150 or the second friction surface 151. Specifically, when the sorting trolley 11 moves and the guide 134 is located at the first guide position, the input wheel 112 enters the guide channel 140, the reversing wheel 128 is separated from the first guide plate 144 and the second guide plate 145, and the pulley 129 rollingly cooperates with the second guide plate 145, so as to drive the driving shaft 127 and the reversing wheel 128 to move in the first direction without rotating, at this time, the conveying belt 111 keeps stationary in the set direction, and as the sorting trolley 11 continues to move, after the input wheel 112 passes through the guide channel 140, the reversing wheel 128 rollingly cooperates with the first friction surface 150, the first friction surface 150 drives the reversing wheel 128 and the driving shaft 127 to rotate forward, so as to drive the conveying belt 111 to convey the articles in the set direction. When the sorting trolley 11 moves and the guide 134 is located at the second guide position, the input wheel 112 enters the guide channel 140, the reversing wheel 128 is separated from the first guide plate 144 and the second guide plate 145, and the pulley 129 rollingly cooperates with the first guide plate 144, so as to drive the driving shaft 127 and the reversing wheel 128 to move in the second direction without rotating, at this time, the conveying belt 111 keeps stationary in the set direction, and as the sorting trolley 11 continues to move, after the input wheel 112 passes through the guide channel 140, the reversing wheel 128 rollingly cooperates with the second friction surface 151, the second friction surface 151 drives the reversing wheel 128 and the driving shaft 127 to rotate reversely, so as to drive the conveying belt 111 to convey the articles in the opposite direction of the set direction. In this way, when the guide 134 is located at different guide positions, the guide channel 140 can guide the driving shaft 127 and the reversing wheel 128 to move to cooperate with the first friction surface 150 or the second friction surface 151, and the guide channel 140 does not directly guide the driving shaft 127 to rotate, that is, the driving shaft 127 and the reversing wheel 128 only move horizontally without rotating, so as to reduce the load of the sorting trolley 11 and the reversing mechanism 130 when the guide channel 140 cooperates with the sorting transmission member. Preferably, the pulley 129 is a bearing which is sleeved on the driving shaft 127.

[0065] Specifically, the reversing mechanism 130 has a transition channel, when the guide 134 is in the intermediate position, the guide channel 140 is opposite and communicates with the transition channel, so as to improve the movement stability of the sorting trolley 11 when the sorting transmission member enters or exits the guide channel 140 of the target bag falling unit. Specifically, the transition channel includes a guide channel 146 and an intermediate channel 152, and the sorting transmission member of the sorting trolley 11 enters the guide channel 140 through the guide channel 146, and when the guide channel 140 is in the intermediate position, the guide channel 140 guides the sorting transmission member to enter the intermediate channel 152.

[0066] Specifically, the base frame 131 includes two limiting plates, both of which are fixedly connected with the fixed plate 122, and the intermediate channel 152 is formed between the two limiting plates. When the guide 134 is in the intermediate position, the outlet of the guide channel 140 is opposite and communicates with the inlet of the intermediate channel 152.

[0067] In the embodiment, the limiting plates are flat plate structures (in other embodiments, the limiting plates can also be replaced by strip-shaped block structures, etc.), and the two limiting plates are parallel and spaced apart along the conveying direction of the conveying belt 111. The two limiting plates can be defined as a first limiting plate and a second limiting plate respectively, the first friction surface 150 is arranged on the first limiting plate, and the second friction surface 151 is arranged on the second limiting plate. Preferably, both of the two limiting plates can be detachably connected with the rack 120, so that the limiting plates can be detached and replaced after being worn out.

[0068] In the embodiment, two limiting plates are fixedly arranged, and each limiting plate is provided with a friction surface, the two friction surfaces correspond to the two guide positions of the guide 134 respectively, and the two friction surfaces can cooperate with the input wheel 112 of the sorting trolley 11 to drive the conveying belt 111 to convey the articles. The embodiment can lengthen the conveying distance of the conveying belt 111 of the sorting trolley 11, thereby increasing the length of the conveying belt 111, so as to adapt to the conveying of larger-sized articles, and reduce the load of the driving member and the load of the sorting trolley 11.

[0069] It should be noted that the "forward rotation" and "reverse rotation" mentioned in the embodiment are relative, for example, the forward rotation is clockwise rotation, and the reverse rotation is counterclockwise rotation. Similarly, the reverse rotation is clockwise rotation, and the forward rotation is counterclockwise rotation.

[0070] Specifically, along the moving direction of the sorting trolley 11, the guide channel 146 is located upstream of the guide 134, the inlet of the guide channel 146 communicates with the outlet of the intermediate channel 152 of the upstream bag falling unit, the outlet of the guide channel 146 communicates with the inlet of the guide channel 140, and the guide channel 146 can guide the input wheel 112 of the sorting trolley 11 passing through the upstream bag falling unit into the guide channel 140 of the present bag falling unit.

[0071] In addition, the reversing mechanism 130 can further include two reset channels, which can be positioned as a first reset channel 153 and a second reset channel 154, respectively, the starting end of the first reset channel 153 being in communication with the end of the first friction surface 150, and the starting end of the second reset channel 154 being in communication with the end of the second friction surface 151, and the ends of the first reset channel 153 and the second reset channel 154 both being in communication with the intermediate channel 152.

[0072] When it is needed to deliver the goods to the first drop pocket, the guide 134 of the reversing mechanism 130 is located at the first guide position, and as the sorting trolley 11 moves, the input wheel 112 passes through the guide channel 140 of the guide 134, in the process, the input wheel 112 drives the conveying belt 111 to deliver the goods in a set direction, when the input wheel 112 reaches the first friction surface 150, the input wheel 112 continues to roll along the first friction surface 150, and continues to drive the conveying belt 111 to deliver the goods in the set direction to the first drop pocket, when the input wheel 112 moves to the end of the first friction surface 150, it is guided to the intermediate channel 152 through the first reset channel 153, and enters the guide channel 146 of the next drop pocket unit through the outlet of the intermediate channel 152.

[0073] When it is needed to deliver the goods to the second drop pocket, the guide 134 of the reversing mechanism 130 is located at the second guide position, and as the sorting trolley 11 moves, the input wheel 112 passes through the guide channel 140 of the guide 134, in the process, the input wheel 112 drives the conveying belt 111 to deliver the goods in the opposite direction of the set direction, when the input wheel 112 reaches the second friction surface 151, the input wheel 112 continues to roll along the second friction surface 151, and continues to drive the conveying belt 111 to deliver the goods in the opposite direction of the set direction to the second drop pocket, when the input wheel 112 moves to the end of the second friction surface 151, it is guided to the intermediate channel 152 through the second reset channel 154, and enters the guide channel 146 of the next drop pocket unit through the outlet of the intermediate channel 152.

[0074] If it is not needed to deliver the goods to the first drop pocket and the second drop pocket, then the guide 134 of the reversing mechanism 130 is in the intermediate position, the input wheel 112 passes through the guide channel 140 and the intermediate channel 152 in turn, and enters the guide channel 146 of the next drop pocket unit through the outlet of the intermediate channel 152.

[0075] The above only describes the preferred embodiments of the present application and is not used to limit the present application, and for those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
