Description

Technical Field

[0001] The present invention relates to the technical field of sorting equipment, and particularly to a sorting trolley of a ring-shaped high-speed cross-belt sorting machine. Background Art

[0002] At present, the ring-shaped cross-belt sorting machine has become the mainstream sorting means in the express delivery industry. Such sorting systems achieve efficient parcel sorting through multiple parallel trolley tracks and a ring-shaped main track. However, in practical applications, when the sorting trolley turns at too high a speed, the friction force provided by the trolley belt is not sufficient to overcome the centrifugal force of the parcel, resulting in the parcel being easily thrown out of the loop. This problem not only affects the stability and safety of the sorting system but also severely restricts the improvement of sorting efficiency.

[0003] In order to prevent parcels from being thrown out during turning in the prior art, the existing ring-shaped cross-belt sorting machines usually adopt the following measures: deceleration strategy: reducing the speed of the sorting trolley in the turning area to ensure that the friction force provided by the trolley belt is sufficient to overcome the centrifugal force of the parcel. Although this method is effective, it also significantly reduces the overall sorting efficiency. Reinforcement design: increasing the thickness of the trolley belt or using higher-performance materials to enhance the friction force. This method can alleviate the problem of parcel throwing to a certain extent, but the cost is high and the problem cannot be completely solved. Auxiliary device: adding an auxiliary guiding device in the turning area. Although there is a certain improvement, it mostly relies on the ring-shaped main track for support, and it is easy to cause movement interference with the reciprocating displacement of the sorting trolley.

[0022] During the specific implementation process: When the sorting trolley 3 is inside the annular guide rail, the permanent magnet on the lower side of the sorting trolley 3 can correspond to the permanent magnet linear motor inside the annular guide rail 1. Then, by using the cooperation of the permanent magnet linear motor and the permanent magnet, the sorting trolley 3 inside the annular guide rail 1 can carry goods for automatic displacement, and then cooperate with the upper bagging mechanism 2, the sorting outlet device 4, the two-dimensional code scanning mechanism 5, and the two-dimensional code recognition mechanism 6 to quickly sort different goods; And because a plurality of sorting trolleys 3 are connected end to end in sequence and a hundred-fold connecting part is arranged between adjacent sorting trolleys 3, the stability of the sorting trolleys 3 during the reciprocating operation on the top of the annular guide rail 1 and the buffering effect on the moving vibration are both in an excellent range, thereby reducing the falling-off probability of goods due to centrifugal force.

A plurality of sorting trolleys 3 are installed on the top of the annular guide rail 1 in a driving manner, and a guide rail driving device is arranged between each of the plurality of sorting trolleys 3 and the top of the annular guide rail 1. Each of the plurality of sorting trolleys 3 includes a trolley body 31. A conveyor belt mechanism 32 is installed on the top of the trolley body 31, and a traveling wheel 33 and a limiting wheel 34 that are in guiding cooperation with the annular guide rail 1 are respectively installed on one side of the bottom of the trolley body 31; The guide rail driving device includes a permanent magnet linear motor and a permanent magnet. The permanent magnet is installed at the bottom of the trolley body 31. The permanent magnet linear motor is arranged on the top of the annular guide rail 1 and can cooperate with the permanent magnet to drive the sorting trolley 3, so that the sorting trolley 3 reciprocates along the annular guide rail 1. Two adjacent trolley bodies 31 among the plurality of trolley bodies 31 are tractionally installed through a connecting shaft until the plurality of sorting trolleys 3 are connected end to end; Inside the middle and one side of the conveyor belt body 321, a hollow space and an annular relief groove 9 are respectively provided. The annular relief groove 9 communicates with the hollow space and a number of reinforcing bars are sleeved inside itself to ensure the structural strength of the annular relief groove 9. A number of negative pressure holes communicating with its own hollow space are provided at the top and bottom of the conveyor belt body 321. An auxiliary ring plate 10 that can fully fit and seal the annular relief groove 9 is sleeved outside one side of the conveyor belt body 321, and one side of the auxiliary ring plate 10 is fixed to the inner wall of one side of the trolley body 31. The auxiliary ring plate 10 serves as a transition structure, which can ensure the sealing performance of the annular relief groove 9 in the non-operating state and also ensure that no specific position needs to be set when the annular relief groove 9 participates in negative pressure absorption subsequently; An air pump 11 is installed on one side of the trolley body 31. A first transition hose 12 is installed between the input end of the air pump 11 and the auxiliary ring plate 10, and one end of the first transition hose 12 communicates with the hollow space. The air pump 11 can form a negative suction environment at the open ports of a number of negative pressure holes through the first transition hose 12 and the hollow space inside the conveyor belt body 321. Subsequently, the air pump 11 performs negative suction linkage on the goods carried on the top of the conveyor belt body 321 through the first transition hose 12, the hollow space inside the conveyor belt body 321, and the negative pressure holes, thereby enhancing the connection strength between the conveyor belt body 321 and the goods and reducing the probability of the goods falling off due to centrifugal motion from the source; A bottom of the auxiliary ring plate 10 is fixedly connected with an extended baffle 19, and the extended baffle 19 can cover and seal a number of negative pressure holes provided at the bottom of the conveyor belt body 321, thereby enhancing the negative pressure adsorption strength of the negative pressure holes in the use state.

[0024] During the specific implementation process: For the sorting trolley 3 to initially stably transport goods and sorting, operate according to the steps in the above-mentioned Embodiment 1; In order to further improve the transportation speed and further reduce the probability of the goods falling off during transportation, after the goods are automatically placed on the top of the conveyor belt mechanism 32 by the upper packing mechanism 2, the air pump 11 can be synchronously started. Then, the input end of the air pump 11 sucks the air in the hollow space inside the conveyor belt body 321 through the first transition hose 12, the auxiliary ring plate 10, and the annular relief groove 9, and then negatively sucks the surface of the goods through a number of negative pressure holes provided at the top of the conveyor belt body 321, enhancing the friction between the goods and the conveyor belt body 321, thereby reducing the probability of the goods falling off due to centrifugal action during transportation; And due to the setting of the annular relief groove 9 and the auxiliary ring plate 10, it can ensure the sealing performance of the annular relief groove 9 in the non-operating state and also ensure that no specific position needs to be set when the annular relief groove 9 participates in negative pressure absorption subsequently. At the same time, the related negative suction structures will not interfere with the movement of the sorting trolley 3 and subsequent active feeding; When the subsequent sorting trolley 3 moves to the corresponding sorting outlet device 4 and needs to convey and discharge materials, the air pump 11 is synchronously closed to release the negative suction effect on the goods, and that's all.

[0025] Embodiment III Please refer to Figure 1 , 4 -8, a sorting trolley of a ring-shaped high-speed cross-belt sorting machine, including a ring-shaped guide rail 1, an upper wrapping mechanism 2 installed inside the ring-shaped guide rail 1, a two-dimensional code scanning mechanism 5, a two-dimensional code recognition mechanism 6, a receiving mesh sheet 8 sleeved outside one side of the ring-shaped guide rail 1, a sorting outlet device 4 installed on the other side of the ring-shaped guide rail 1, a working ladder 7 for working at heights. A plurality of sorting trolleys 3 are installed on the top of the ring-shaped guide rail 1 in a driving manner, and a guide rail driving device is arranged between each of the plurality of sorting trolleys 3 and the top of the ring-shaped guide rail 1. Each of the plurality of sorting trolleys 3 includes a trolley body 31. A conveyor belt mechanism 32 is installed on the top of the trolley body 31. On one side of the bottom of the trolley body 31, a traveling wheel 33 and a limiting wheel 34 that are in guiding cooperation with the ring-shaped guide rail 1 are respectively installed. The guide rail driving device includes a permanent magnet linear motor and a permanent magnet. The permanent magnet is installed at the bottom of the trolley body 31. The permanent magnet linear motor is arranged on the top of the ring-shaped guide rail 1 and can cooperate with the permanent magnet to drive the sorting trolley 3, so that the sorting trolley 3 reciprocates along the ring-shaped guide rail 1. Two adjacent trolley bodies 31 among the plurality of trolley bodies 31 are traction-installed through a connecting shaft until the plurality of sorting trolleys 3 are connected end to end. A hollow space and an annular relief groove 9 are respectively formed inside the middle part and one side of the conveyor belt body 321. The annular relief groove 9 communicates with the hollow space and a plurality of reinforcing strips are sleeved inside itself to ensure the structural strength of the annular relief groove 9. A plurality of negative pressure holes communicating with the hollow space of the conveyor belt body 321 are formed at the top and bottom of the conveyor belt body 321. An auxiliary ring plate 10 that can fully fit and seal the annular relief groove 9 is sleeved outside one side of the conveyor belt body 321, and one side of the auxiliary ring plate 10 is fixed to the inner wall of one side of the trolley body 31. The auxiliary ring plate 10 serves as a transition structure, which can ensure the sealing performance of the annular relief groove 9 in the non-operating state and can also ensure that there is no need to set a specific position when the annular relief groove 9 participates in negative pressure suction subsequently. An air pump 11 is installed on one side of the trolley body 31. A first transition hose 12 is installed between the input end of the air pump 11 and the auxiliary ring plate 10, and one end of the first transition hose 12 communicates with the hollow space. The air pump 11 can form a negative suction environment at the open ports of a number of negative pressure holes through the first transition hose 12 and the hollow space inside the conveyor belt body 321. Subsequently, the air pump 11 performs negative suction linkage on the goods carried on the top of the conveyor belt body 321 through the first transition hose 12, the hollow space inside the conveyor belt body 321, and the negative pressure holes, thereby enhancing the connection strength between the conveyor belt body 321 and the goods, and reducing the probability of the goods falling off due to centrifugal motion from the source; Positioning frame plates 14 are installed at the front ends on both sides of the trolley body 31, and an adjusting shaft 13 is sleeved between the two positioning frame plates 14 through bearings. A material blocking frame plate 15 is sleeved on the surface of the adjusting shaft 13, thus providing a structural condition for subsequent hard blocking of falling off. An air-driven output assembly 16 is installed on the surface of one side of the trolley body 31. A second transition hose 17 is installed between the rear end of the air-driven output assembly 16 and the output end of the air pump 11. An engaging transmission assembly 18 capable of drivingly connecting with the adjusting shaft 13 is arranged on the output structure inside the air-driven output assembly 16. The second transition hose 17 serves as a transition structure to link the air-driven output assembly 16, the engaging transmission assembly 18 and the air pump 11, and then, without interfering with the original operating function of the air pump 11, the air flow kinetic energy output by the air pump 11 is extended for use; The air-driven output assembly 16 includes a support cylinder 161 and a piston rod 162. The piston rod 162, as the output structure of the air-driven output assembly 16, is clamped with the support cylinder 161, and one end of the piston rod 162 penetrates through the support cylinder 161 and extends to the outside of the support cylinder 161. A return spring 163 is sleeved on the other end of the piston rod 162, and both ends of the return spring 163 are respectively installed on the surface of the other end of the piston rod 162 and the inner wall of the support cylinder 161. A sealing ring is nested at the penetration and sleeving part of the piston rod 162 and the support cylinder 161 to improve the sleeving and sealing effect between the piston rod 162 and the support cylinder 161. The rear end of the support cylinder 161 is connected to one end of the second transition hose 17, and a pressure relief pipe for relieving the pressure of its own space is arranged at the top of the rear end of the support cylinder 161, thereby facilitating the self-pressure relief and reset of the air-driven output assembly 16 and providing favorable conditions for the sustainable use of the air-driven output assembly 16; The meshing transmission assembly 18 includes a transmission gear 181 and a spur plate 182. The inner middle side of the transmission gear 181 is sleeved on the outer side of the end of one end of the adjusting shaft 13. The spur plate 182 meshes with the transmission gear 181 for transmission, and one end of the spur plate 182 is in transmission connection with the end of one end of the piston rod 162. The spur plate 182 meshes with the transmission transmission gear 181 under the gas stamping transmission of the air pump 11 through the second transition hose 17 and the pneumatic output assembly 16, so that the transmission gear 181 drives the adjusting shaft 13 and the material blocking frame plate 15 to flip and adjust to the front end of the trolley body 31, thereby realizing active hard blocking protection for the output port of the sorting trolley 3, and the material blocking frame plate 15 will not interfere with the moving material feeding of the sorting trolley 3 whether it is in an upright blocking state or in a storage state. The material baffle frame 15 is flipped and adjusted to have a filling groove on its structural surface facing the trolley body 31, in which a double-sided adhesive layer 20 is nested. The double-sided adhesive layer 20 is used as a reinforcement between the goods that come into contact with the material baffle frame 15 and the material baffle frame 15. In the subsequent unloading process when the sorting trolley 3 arrives at the corresponding sorting outlet device 4, the flipped and reset material baffle frame 15 can drive the goods to move synchronously, thereby speeding up the removal of the goods and reducing the load and energy consumption of the feeding operation of the sorting trolley 3 in disguise.

[0026] During the specific implementation process: The sorting trolley 3 transports goods in a negative suction state and sorts the goods according to the steps of the above-mentioned embodiment 2; In order to further increase the transportation speed, further reduce the probability of cargo falling off during transportation, and re-utilize the kinetic energy of the airflow output by the air pump 11, the specific principle is as follows; The air pump 11 starts to suck air from the first transition hose 12, and then the air pumped by the air pump 11 is discharged through the second transition hose 17; The air discharged through the second transition hose 17 will enter the interior of the support cylinder 161. Subsequently, as the air pumped by the air pump 11 is continuously transported to the interior of the support cylinder 161 through the second transition hose 17, the pressure inside the support cylinder 161 gradually increases and gradually presses the piston rod 162 after reaching a balance point, thereby causing the piston rod 162 to move forward in a straight line. During the process of the piston rod 162 moving forward in a straight line, the return spring 163 will change from its original naturally expanded state to a compressed state, thereby preparing for the subsequent automatic return of the piston rod 162. At the same time, the piston rod 162 drives the spur plate 182 to automatically move, the support cylinder 161 provides a snap-on guide, and the return spring 163 is compressed to make way. The moved spur plate 182 will mesh with the transmission gear 181, causing the transmission gear 181 to rotate clockwise and drive the adjustment shaft 13 and the material blocking frame plate 15 to rotate synchronously and in the same direction, until the material blocking frame plate 15 changes from a state stored at the bottom of the front end of the conveyor belt mechanism 32 to a state vertically parallel to the conveyor belt mechanism 32, and then a hard blocking condition is set outside the output front end of the conveyor belt mechanism 32 to prevent the goods from falling off during transportation, and due to the setting of the pressure relief pipe, the air pressure inside the support cylinder 161 will reach a certain peak value and be balanced to ensure the stability of the upright material blocking frame plate 15; When the subsequent sorting trolley 3 moves to the corresponding sorting outlet device 4 for conveying and unloading, the air pump 11 is synchronously turned off to release the negative suction effect on the goods. At the same time, the piston rod 162 inside the support cylinder 161 will drive the spur plate 182 to automatically reset under the reset elastic force of the reset spring 163, and the pressure relief pipe provides the condition for the excess air inside the support cylinder 161 to be discharged. Similarly, due to the meshing transmission of the transmission gear 181 and the spur plate 182, the adjustment shaft 13 and the material blocking frame plate 15 will also be reset synchronously. In this way, the restriction on the front end of the sorting trolley 3 is released, and then the trolley body 31 can automatically convey and unload the goods.
