Description

Technical Field

[0001] The present invention relates to the technical field of sorting, and particularly to an express sorting device. Background Art

[0002] In current logistics sorting equipment, the commonly used cross-belt sorting device is such that on a track, trolleys (referred to as sorting trolleys for short) carrying small belt conveyors are evenly arranged. The main drive belt conveyor and the trolleys (referred to as sorting trolleys for short) carrying small belt conveyors are connected together, and several sorting ports are arranged on both sides of the track. During operation, power is provided by the main motor to drive all sorting trolleys to run on the track. When the sorting trolley moves to the specified sorting position, the motor of the sorting trolley drives the belt to rotate, driving the goods on the belt of the sorting trolley to move horizontally, thus completing the task of sorting the goods to the target sorting port. Because the main drive belt conveyor and the belt conveyor on the sorting trolley are in a cross shape, it is called a cross-belt sorting machine.

[0003] Currently, for such a cross-belt sorting machine, in order to make the express delivery on the sorting trolley move horizontally to the target sorting port, a motor is configured on the traditional sorting trolley. This motor drives the belt on the sorting trolley to rotate, driving the goods to move horizontally to the target sorting port. At the same time, a power receiving element needs to be specially set on the belt conveyor of the sorting trolley, and a sliding contact type conductive system for the sorting trolley motor also needs to be configured on the track. In order to ensure the accurate operation of the sorting trolley motor, a corresponding sorting trolley motor control system, position monitoring module, communication module, and sliding contact wire, etc. must also be supported. As a result, the entire device has a complex structure, high cost, and at the same time, the number of fault points increases, and the reliability of the device decreases. Summary of the Invention

[0004] In order to overcome the deficiencies of existing research, the present invention provides an express sorting device, which is ingeniously designed. It adopts the meshing drive of the sorting action component and the sorting trolley. The sorting trolley does not require a dedicated drive motor and its power receiving element, and there is no need to equip a sliding contact type conductive system for the drive motor on the running track, nor is it necessary to equip a control system, position monitoring module, communication module, and sliding contact wire, etc. that are supporting the drive motor. It simplifies the structure, saves energy and reduces consumption, reduces costs, reduces the number of fault points, has more stable and reliable performance, simpler control, and higher working efficiency. To achieve the above functions, the above technical problems of the present invention are mainly solved by the following technical solutions:

[0005] The present invention provides an express sorting device, which includes a sorting trolley, a traveling power assembly, a sorting action assembly, and a traveling track. The sorting trolley is fixed on the traveling power assembly, the sorting action assembly is fixedly installed on the traveling track, and a linear motor is installed on the traveling track. The linear motor drives the traveling power assembly to run on the traveling track through a power plate on the traveling power assembly. The cylindrical driving roller in the sorting action assembly is in meshing transmission connection with the spiral grooves of the left screw rod / right screw rod of the sorting trolley to drive the conveyor belt in the sorting trolley to operate.

[0006] The lateral transportation of the sorting trolley itself is driven by the meshing transmission connection between the cylindrical driving roller in the sorting action assembly and the spiral grooves of the left / right screw rod of the sorting trolley. The required driving power of the cylindrical driving roller is relatively small, and there is no need for a dedicated driving motor and its current receiving components. There is no need to equip the traveling track with a sliding contact conductive system for the driving motor, nor is it necessary to equip a control system, a position monitoring module, a communication module, a sliding contact wire, etc. that are matched with the driving motor. This simplifies the structure, saves energy, reduces costs, reduces the number of fault points, and the performance is more stable and reliable.

[0007] Furthermore, the sorting trolley includes front and rear side plates, which are fixedly connected by connecting profiles. Seat bearings are respectively installed at the lower left, middle, and lower right parts of the front and rear side plates. A right screw rod is rotatably connected between the seat bearings at the lower right part of the front and rear side plates, and a left screw rod is rotatably connected between the seat bearings at the lower left part of the front and rear side plates. A left-handed spiral groove is provided on the left screw rod, and a right-handed spiral groove is provided on the right screw rod. An intermediate shaft is rotatably connected between the seat bearings at the middle and lower parts of the front and rear side plates. The right screw rod is connected to the intermediate shaft through a first synchronous belt transmission mechanism, and the left screw rod is connected to the intermediate shaft through a second synchronous belt transmission mechanism. A driving shaft is rotatably connected between the upper left parts of the front and rear side plates through a first side plate connecting piece and a main driving bearing, and a driven shaft is slidably connected between the upper right parts of the front and rear side plates through a second side plate connecting piece. The intermediate shaft is connected to the driving shaft through a speed increasing belt transmission mechanism, and the driving shaft is connected to the driven shaft through a sorting synchronous belt transmission mechanism. A conveyor belt is fixed on the sorting synchronous belt in the sorting synchronous belt transmission mechanism. Positioning bead supports are respectively fixed on the inner side of the right part of the front side plate and the inner side of the left part of the rear side plate. The positioning bead supports are threadedly connected with spring positioning beads, and the spring positioning beads are matched with the positioning holes on the rear end face of the left screw rod / the front end face of the right screw rod.

[0008] The sorting trolley is provided with spiral grooves on the spiral rod to cooperate with the meshing transmission of the cylindrical driving rollers in the sorting action assembly. The spiral rod is connected to the intermediate shaft through a synchronous belt transmission mechanism, and the intermediate shaft is connected to the driving shaft through a speed increasing transmission mechanism, so as to drive the sorting synchronous belt to operate, then drive the sorting synchronous belt to rotate, drive the conveyor belt to rotate, and finally realize the arrival of the express at the target sorting port. When the cylindrical driving roller meshes with the spiral rod, the spring positioning bead automatically disengages from the end face of the spiral rod. When the cylindrical driving roller separates from the spiral rod, the spring positioning bead automatically cooperates with the positioning hole on the end face of the spiral rod for positioning.

[0009] The sorting trolley is respectively provided with a left spiral rod and a right spiral rod, so that the conveyor belt can be rotated counterclockwise / clockwise, and the express can reach the target sorting ports in two directions on both sides of the walking track respectively.

[0010] Furthermore, a support plate is arranged in cooperation with the lower part of the conveyor belt. The support plate includes an intermediate support plate and arc-shaped support plates at its left and right ends. The left and right ends of the intermediate support plate are fixedly connected to the arc-shaped support plates, and the intermediate support plate is fixedly arranged between the front and rear side plates.

[0011] The function of the support plate is to support the conveyor belt, making the conveying of the conveyor belt more stable and capable of carrying heavier express deliveries.

[0012] Furthermore, first side plate connectors are fixedly connected to the outer sides of the front and rear side plates where the two ends of the driving shaft are located, and second side plate connectors are fixedly connected to the outer sides of the front and rear side plates where the two ends of the driven shaft are located. The front and rear ends of the driven shaft are slidably connected to the adjustment holes of the second side plate connectors, and the second side plate connectors are radially adjustably and fixedly connected to the driven shaft through adjustment screws.

[0013] By loosening the adjustment screws, the driven shaft is in an adjustable state, and the driven shaft can slide in the adjustment holes of the side plate connectors, so as to adjust the center distance between the driven shaft and the driving shaft, and thus adjust the tightness of the sorting synchronous belt, making the conveyor belt better convey the express.

[0014] Furthermore, the synchronous belt transmission mechanism I includes a driving synchronous pulley I, a synchronous belt I, and a driven synchronous pulley I. The driving synchronous pulley I is connected to the driven synchronous pulley I through the synchronous belt I. The driving synchronous pulley I is fixed to the rear part of the right spiral rod, and the driven synchronous pulley I is fixed to the rear part of the intermediate shaft. The synchronous belt transmission mechanism I is located inside the rear side plate;

[0015] The synchronous belt transmission mechanism II includes a driving synchronous pulley II, a synchronous belt II, and a driven synchronous pulley II. The driving synchronous pulley II is connected to the driven synchronous pulley II through the synchronous belt II. The driving synchronous pulley II is fixed to the front part of the left spiral rod, and the driven synchronous pulley II is fixed to the front part of the intermediate shaft. The synchronous belt transmission mechanism II is located inside the front side plate.

[0016] The synchronous belt drive mechanism I is located inside the front side plate, leaving the outer space of the front side plate for installing the speed-increasing synchronous belt drive mechanism.

[0017] Furthermore, the speed-increasing belt drive mechanism includes a driving large pulley, a speed-increasing belt, and a driven small pulley. The driving large pulley is connected to the driven small pulley through the speed-increasing belt. The driving large pulley is fixed to the rear end of the intermediate shaft, and the driven small pulley is fixed to the rear end of the driving shaft. The speed-increasing belt drive mechanism is located outside the rear side plate.

[0018] The intermediate shaft and the driving shaft adopt a speed-increasing belt drive mechanism, which converts the lower rotational speed of the intermediate shaft into a higher rotational speed, so that the express delivery can be more quickly transported to the target sorting port.

[0019] Furthermore, the sorting synchronous belt drive mechanism includes a sorting driving pulley, a sorting synchronous belt, and a sorting driven pulley. The sorting driving pulley is connected to the sorting driven pulley through the sorting synchronous belt. The front and rear parts of the driving shaft are respectively fixed with sorting driving pulleys, and the front and rear parts of the driven shaft are respectively rotatably connected with sorting driven pulleys through driven bearings. The sorting synchronous belt drive mechanism is located between the front and rear side plates.

[0020] Furthermore, the sorting synchronous belt is a toothed belt, and T-shaped nuts are embedded in each tooth of the toothed belt. The sorting synchronous belt is fixedly connected to the conveyor belt through the cooperation of T-shaped nuts and connecting screws.

[0021] Embedding T-shaped nuts in each tooth of the sorting synchronous belt and connecting them with connecting screws to connect the conveyor belt makes the connection between the sorting synchronous belt and the conveyor belt more stable and firm.

[0022] Furthermore, the walking power assembly includes a power plate. A bracket is fixedly connected to the power plate. An installation hole is provided in the center of the bracket. Two connecting plates are respectively fixedly installed at the front and rear parts of the bracket. The two connecting plates are respectively fixedly connected to the front and rear side plates of the sorting trolley. A walking wheel is rotatably connected to the rear part of the bracket, and a guiding wheel is installed at the bottom rear part of the bracket. An outer ball head connector is installed in the installation hole, and the outer ball head connector forms a ball head pair connection with the inner ball head. Adjacent walking power assemblies are connected to each other through the outer ball head connector and the inner ball head.

[0023] The power plate is provided to be connected to the linear motor on the walking guide rail. The bracket is provided to support the sorting trolley. The outer joint connector is provided to pass through the installation hole of the bracket to connect the front and rear sorting trolleys. The outer ball head connector and the inner ball head form a ball head pair, so that the two interconnected sorting trolleys form a ball head pair connection, so that the two interconnected sorting trolleys can move flexibly. The connecting plate is provided for fixedly connecting with the front and rear side plates of the sorting trolley. The walking wheel cooperates with the upper part of the walking track to roll to realize the walking of the walking power assembly on the walking track. The guiding wheel cooperates with the side plate of the walking track to play a guiding role.

[0024] Furthermore, the sorting action component includes a support frame. A bottom plate is fixed on the support frame. A sliding seat and an electromagnet are fixed on the bottom plate. The guide rod is slidably connected to the sliding seat. The electromagnet telescopic rod passes through the electromagnet and is slidably connected to the electromagnet. One end of the guide rod is fixedly connected to the electromagnet telescopic rod. A return spring is arranged on the electromagnet telescopic rod. A shock-absorbing rubber ring is installed on the guide rod. The other end of the guide rod is fixedly connected with a cylindrical driving roller. The cylindrical driving roller is meshed and connected with the spiral groove of the left screw rod / right screw rod. The support frame is fixedly connected with the walking track.

[0025] The bottom plate is provided for the fixed connection with the walking track. The electromagnet telescopic rod drives the guide rod to expand and contract by the electrification and expansion of the electromagnet, so as to realize the meshing transmission between the cylindrical driving roller and the spiral groove of the screw rod. The arrangement of the return spring on the electromagnet telescopic rod enables the electromagnet telescopic rod to automatically reset after the electromagnet is powered off. The installation of the shock-absorbing rubber ring on the guide rod enables the expansion and contraction of the guide rod to be shock-absorbed, making the expansion and contraction of the guide rod smoother.

[0026] The beneficial effects of the present invention.

[0027] 1. For this express sorting device of the present invention, only by energizing the electromagnet in the sorting action component to drive the electromagnet telescopic rod to extend, the cylindrical driving roller is meshed and rotated with the spiral groove of the screw rod in the sorting trolley, thereby driving the screw rod to rotate, and then through a series of belt transmission mechanisms, the transverse rotation of the conveyor belt is realized, and finally the lateral entry of the express into the target sorting port is realized.

[0028] 2. For this express sorting device of the present invention, there is no need for a driving motor in the sorting trolley. It is driven by energizing the electromagnet in the sorting action component. After driving, it is powered off. The electromagnet responds quickly and accurately, improving work efficiency. And the power required by the electromagnet is much smaller than the power of the driving motor required to drive the conveyor belt. For example, the power required by a single electromagnet is 20 watts, and the power of two electromagnets is only 40 watts, while the power of the driving motor of the traditional sorting trolley with a driving motor is 400 watts, reducing the power configuration by 90%, saving energy and reducing consumption, reducing costs, with simpler control, more reliable and stable performance, and higher work efficiency.

[0029] 3. For this express sorting device of the present invention, the design is ingenious. It adopts the meshing drive of the sorting action component and the sorting trolley. The sorting trolley does not require a dedicated driving motor and its power receiving components. There is no need to equip a sliding contact type conductive system for the driving motor on the walking track, nor is it necessary to equip a control system, a position monitoring module, a communication module and a sliding contact wire matching the driving motor, etc. The structure is simplified, energy is saved, costs are reduced, the number of fault points is reduced, and the performance is more stable and reliable.

[0030] 4. In the sorting trolley of this express sorting device of the present invention, when the cylindrical driving roller meshes with the screw rod, the spring positioning bead automatically disengages from the end face of the screw rod and loses its positioning. When the cylindrical driving roller separates from the screw rod, the spring positioning bead automatically cooperates with the positioning hole on the end face of the screw rod again for positioning. The use of the spring positioning bead for automatic positioning / losing positioning helps the express to accurately reach the target sorting port.

[0031] 5. In the sorting trolley of this express sorting device of the present invention, by loosening the adjusting screw, the driven shaft is in an adjustable state. The driven shaft can move left and right in the adjusting hole of the side plate connecting piece, thereby adjusting the intermediate distance between the driven shaft and the driving shaft, making the tension of the sorting synchronous belt adjustable and enabling the sorting synchronous belt to operate better.

[0032] 6. In the sorting action assembly of this express sorting device of the present invention, the electromagnetic iron telescopic rod drives the guide rod to expand and contract through the electrification and expansion / contraction of the electromagnetic iron, thereby realizing the meshing transmission between the cylindrical driving roller and the spiral groove of the screw rod. The setting of the return spring on the electromagnetic iron telescopic rod enables the electromagnetic iron telescopic rod to automatically reset after the power of the electromagnetic iron is cut off. A shock-absorbing rubber ring is installed on the guide rod to shock-absorb the expansion and contraction of the guide rod, making the expansion and contraction of the guide rod smoother, and thus realizing the stable meshing between the cylindrical driving roller and the screw rod.

A linear motor is installed on the traveling track 4. The linear motor drives the traveling power assembly 2 to run on the traveling track 4 through the power plate 24 on the traveling power assembly 2. The cylindrical driving roller 37 in the sorting action assembly 3 is engaged with the spiral groove of the left screw rod 112 / right screw rod 101 of the sorting trolley 1 to drive the conveyor belt 124 in the sorting trolley 1 to operate.

[0057] The lateral transport of the sorting trolley 1 itself is driven by the cylindrical drive roller 37 in the sorting action component 3 and the spiral groove meshing transmission connection of the left / right spiral rod of the sorting trolley 1. The required driving power of the cylindrical drive roller 37 is relatively small, and no special drive motor and its power receiving element are required. The walking track 4 does not need to be equipped with a sliding contact conductive system of the drive motor, nor does it need to be equipped with a control system, position monitoring module, communication module and sliding bus bar that match the drive motor. This simplifies the structure, saves energy, reduces costs, reduces failure points, and makes the performance more stable and reliable.

When the cylindrical driving roller 37 meshes with the screw rod, the spring positioning bead 120 automatically disengages from the end face of the screw rod. When the cylindrical driving roller 37 separates from the screw rod, the spring positioning bead 120 automatically cooperates with the positioning hole on the end face of the screw rod for positioning.

The left and right ends of the intermediate support plate 126 are fixedly connected to the arc-shaped support plates 127, and the intermediate support plate 126 is fixedly installed between the front and rear side plates 104 in the front and rear directions.

[0062] The function of the support plate is to support the conveyor belt 124, making the conveyance of the conveyor belt 124 more stable and enabling it to carry heavier express deliveries.

An outer ball head connector 22 is installed in the installation hole 23. The outer ball head connector 22 forms a ball head pair connection with the inner ball head 21. Adjacent walking power assemblies 2 are connected to each other through the outer ball head connector 22 and the inner ball head 21.

[0074] The power plate 24 is provided to be connected to the linear motor on the walking guide rail 4. The bracket 27 is provided to support the sorting trolley 1. The outer joint connector 22 is provided to pass through the installation hole 23 of the bracket 27 to connect the front and rear two sorting trolleys 1. The outer joint connector 22 and the inner ball head 21 form a ball head pair, enabling the two mutually connected sorting trolleys 1 to form a ball head pair connection, so that the two mutually connected sorting trolleys 1 can move flexibly. The connecting plate 28 is provided for fixedly connecting to the front and rear side plates 104 of the sorting trolley 1. The walking wheel 25 cooperates with the upper part of the walking track 4 to roll to realize the walking of the walking power assembly 2 on the walking track 4. The guide wheel 26 cooperates with the side plate 104 of the walking track 4 to play a guiding role.

[0075] The sorting action component 3 includes a support frame 31, a bottom plate 32 is fixed on the support frame 31, a sliding seat 35 and an electromagnet 33 are fixed on the bottom plate 32, a guide rod 36 is slidably connected to the sliding seat 35, an electromagnet telescopic rod 331 passes through the electromagnet 33 and is slidably connected to the electromagnet 33, one end of the guide rod 36 is fixedly connected to the electromagnet telescopic rod 331, a return spring is arranged on the electromagnet telescopic rod 331, a shock-absorbing rubber ring 34 is installed on the guide rod 36, and a cylindrical driving roller 37 is fixed at the other end of the guide rod 36. The cylindrical driving roller 37 is meshed and connected with the spiral groove of the left screw rod 112 / right screw rod 101, and the support frame 31 is fixedly connected to the walking track 4.

[0076] The bottom plate 32 is provided for fixed connection in cooperation with the walking track 4. The electromagnet telescopic rod 331 drives the guide rod 36 to expand and contract through the electrification and expansion of the electromagnet 33, so as to realize the meshing transmission between the cylindrical driving roller 37 and the spiral groove of the screw rod. The setting of the return spring on the electromagnet telescopic rod 331 enables the electromagnet telescopic rod 331 to automatically reset after the electromagnet 33 is powered off. The installation of the shock-absorbing rubber ring 34 on the guide rod 36 shocks the expansion and contraction of the guide rod 36, making the expansion and contraction of the guide rod 36 smoother.

[0077] The working principle and process of the present invention.

[0078] As Figures 1-13 shown, when this express sorting device works, workers or automated devices place each express on the conveyor belt 124 in the sorting trolley 1. The linear motor on the walking track 4 drives the power plate 24, so that the walking power component 2 walks on the walking track 4. The recognition system automatically scans and recognizes the information on the express to confirm which express sorting port it should be placed in.

[0079] Taking a certain express sorting port on the right side of the walking track 4 as the target position of the express as an example, when the express is about to approach the target sorting port, the control system issues an instruction to energize the electromagnet 33 in the sorting action component 3. The electromagnet 33 is energized and the electromagnetic telescopic rod 331 extends outwards. The electromagnet telescopic rod 331 drives the guide rod 36 and its cylindrical driving roller 37 to extend outwards together. Since the right screw rod 101 is provided with a large-pitch right-handed spiral groove, when the sorting trolley 1 passes through the sorting action component 3, the cylindrical driving roller 37 just fits into the large-pitch spiral groove of the right screw rod 101 for meshing transmission. At this time, the sorting trolley 1 continues to move forward, and the right screw rod 101 rotates clockwise under the drive of the cylindrical driving roller 37. When the right screw rod 101 rotates, the spring positioning bead 120 automatically disengages from the positioning hole on the right screw rod 101 (in the initial state, the spring positioning bead 120 is engaged and positioned in the positioning hole on the front end face of the right screw rod).

[0080] The right screw rod 101 rotates clockwise to drive the intermediate shaft 122 to rotate clockwise through the first synchronous belt transmission mechanism. The intermediate shaft 122 rotates clockwise to drive the driving shaft 111 to rotate clockwise and accelerate through the speed-increasing belt transmission mechanism. The driving shaft 111 rotates clockwise and runs clockwise through the sorting synchronous belt transmission mechanism. The sorting synchronous belt 110 in the sorting synchronous belt transmission mechanism rotates clockwise. The sorting synchronous belt 110 rotates clockwise to drive the conveyor belt 124 to rotate clockwise, thereby driving the express delivery on the conveyor belt 124 to move to the right until it falls into the corresponding target sorting opening below it.

[0081] Since the large-pitch right-handed helical groove on the right screw rod 101 is a single-turn helical groove, when the cylindrical driving roller 37 disengages from the large-pitch helical groove of the right screw rod 101, the right screw rod 101 just rotates clockwise for one circle. When the large-pitch right-handed helical groove of the right screw rod 101 disengages from the cylindrical driving roller 37, the spring positioning bead 120 automatically cooperates with the positioning hole on the front end face of the right screw rod 101 for positioning under the action of its own return spring. At the same time, when the cylindrical driving roller 37 disengages from the large-pitch right-handed helical groove of the right screw rod 101, the control system issues an instruction to cut off the power supply of the electromagnet 33. The electromagnet 33 cuts off the power supply, and the electromagnet telescopic rod 331 drives the guide rod 36 and its cylindrical driving roller 37 back to the initial position under the action of the return spring to avoid misdriving the next sorting trolley 1. Thus, the sorting work of one piece of express delivery is completed.

[0082] When the target sorting opening of the express delivery is on the left side of the walking track 4, the left screw rod 112 on the left side rotates counterclockwise according to the instruction to realize the counterclockwise rotation of the left-handed screw rod, thereby realizing the counterclockwise rotation of the conveyor belt 124, so that the express delivery moves to the left along the conveyor belt 124 until it enters the corresponding target sorting opening below it.

[0083] The left screw rod 112 and the right screw rod 101 can be used alone to realize the one-way sorting of express delivery, and the left screw rod 112 and the right screw rod 101 can also be exchanged to achieve different sorting effects.

[0084] For this kind of express delivery sorting device, only by energizing the electromagnet 33 in the sorting action assembly 3 to drive the electromagnet telescopic rod 331 to extend, the cylindrical driving roller 37 is engaged with the helical groove of the screw rod in the sorting trolley 1 to rotate, thereby driving the screw rod to rotate, and then through a series of belt transmission mechanisms, the transverse rotation of the conveyor belt 124 is realized, and finally the transverse entry of the express delivery into the target sorting opening is realized.

[0085] In this express sorting device, there is no need for a driving motor in the sorting trolley 1. It is driven by energizing the electromagnet 33 in the sorting action component 3. Once the driving is completed, the power supply is cut off. The electromagnet 33 responds quickly and accurately, improving work efficiency. Moreover, the power required by the electromagnet 33 is much smaller than that of the driving motor required for driving the conveyor belt 124. For example, the power required for a single electromagnet 33 is 20 watts, and the power of two electromagnets 33 is only 40 watts, while the power of the driving motor of the traditional sorting trolley 1 with a driving motor is 400 watts, reducing the power configuration by 90%, saving energy and reducing consumption, reducing costs, with simpler control, more reliable and stable performance, and higher work efficiency.

[0086] This express sorting device is ingeniously designed and adopts the meshing drive of the sorting action component 3 and the sorting trolley 1. The sorting trolley 1 does not require a dedicated driving motor and its power receiving components, and the walking track 4 does not need a sliding contact conductive system for the driving motor, nor does it need a control system, position monitoring module, communication module, and sliding contact wire that are matched with the driving motor, simplifying the structure, saving energy, reducing costs, reducing the number of fault points, and having more stable and reliable performance.

[0087] In the sorting trolley 1 of this express sorting device, when the cylindrical driving roller 37 meshes with the screw rod, the spring positioning bead 120 automatically disengages from the end face of the screw rod and loses its positioning. When the cylindrical driving roller 37 separates from the screw rod, the spring positioning bead 120 automatically cooperates with the positioning hole on the end face of the screw rod again for positioning. The use of the spring positioning bead 120 for automatic positioning / losing positioning helps the express to accurately reach the target sorting port.

[0088] In the sorting trolley 1 of this express sorting device, by loosening the adjusting screw 118, the driven shaft 121 is in an adjustable state. The driven shaft 121 can move left and right in the adjusting hole of the side plate connecting piece, thereby adjusting the intermediate distance between the driven shaft 121 and the driving shaft 111, making the tension of the sorting synchronous belt 110 adjustable and enabling the sorting synchronous belt 110 to operate better.

[0089] In the sorting action component 3 of this express sorting device, the electromagnet telescopic rod drives the guide rod 36 to expand and contract by energizing and expanding the electromagnet 33, thereby realizing the meshing transmission between the cylindrical driving roller 37 and the spiral groove of the screw rod. The setting of the return spring on the electromagnet telescopic rod enables the electromagnet telescopic rod 331 to automatically reset after the electromagnet 33 is powered off. A shock-absorbing rubber ring 34 is installed on the guide rod 36 to damp the expansion and contraction of the guide rod 36, making the expansion and contraction of the guide rod 36 smoother, thereby realizing the smooth meshing between the cylindrical driving roller 37 and the screw rod.

[0090] Although the present invention has been illustrated and described by reference to the preferred embodiments, those of ordinary skill in the art should understand that various changes in form and detail may be made within the scope of the claims.
