Description

Technical Field

[0001] This invention relates to the field of material conveying technology, specifically to a guide wheel mechanism for a cross-belt sorting machine trolley and its guiding method. Background Technology

[0002] Cross-belt sorters are one of the core pieces of equipment in modern logistics distribution centers. Their sorting carts, as key components for carrying and transporting materials, need to run at high speed and stably on a circular track during the sorting process.

[0003] In the prior art, such as the "cross-belt sorting machine traveling trolley" disclosed in Chinese patent CN201520736139.2, this patent includes an upper conveyor belt, a middle trolley frame, and a lower secondary plate. The middle trolley frame includes a frame body, a guide wheel assembly, and a traveling wheel assembly. Its characteristic is that the frame body is a T-shaped integrated structure formed by a crossbeam and a longitudinal beam fixedly connected. Mounting holes are opened at both ends of the crossbeam. Two traveling wheels in the traveling wheel assembly are symmetrically installed at both ends of the crossbeam, and two guide wheels in the guide wheel assembly are installed at the bottom of the crossbeam. This reduces the number of parts, simplifies the structure, and makes the middle trolley frame easy and quick to install, with high processing precision.

[0004] However, in this patent, the guide wheel is fixedly installed, which can only play a passive limiting role and cannot sense the contact state between the guide wheel and the track in real time. When the trolley passes through the track curve or the track joint, the contact pressure between the guide wheel and the side of the track will change drastically. Due to the lack of real-time monitoring of the force state of the guide wheel, the control system cannot know the actual alignment of the trolley in the track. This causes the side of the traveling wheel to hit the side wall of the track when the trolley is running on the curve, which generates a lot of vibration and noise and accelerates the wear of the guide wheel. In addition, the existing sorting trolley's conveying mechanism and guiding mechanism are independent of each other. When the trolley deviates in the track, it is impossible to compensate for the material position through the active adjustment of the conveying mechanism. It can only rely on the mechanical structure to passively correct the deviation, which has limited correction capability. Summary of the Invention

[0025] Guiding method of guide wheel mechanism of cross belt sorting machine trolley;

[0026] S1: The guide wheel mechanism is fixedly installed on both sides of the main frame via the guide wheel mounting beam, and the guide wheel body in the guide assembly is in contact with the sorting machine track;

[0027] S2: Start the sorting machine. The trolley runs along the track, and the guide wheels roll on the track to guide the trolley's running direction.

[0028] S3: During the guiding process, the displacement sensor detects the radial displacement of the guide wheel body in real time due to uneven track or wear of the guide wheel, and outputs the displacement signal to the external control system.

[0029] S4: The external control system determines the wear level of the guide wheel body or the flatness of the track based on the received displacement signal.

[0030] As a preferred embodiment of the present invention, the external control system compares the received displacement signal with a preset threshold: when the displacement exceeds the preset threshold, an alarm signal is issued to replace the guide wheel or repair the track.

[0031] When the displacement is within the preset threshold, the trolley continues to operate normally.

[0032] The working principle and beneficial effects of this invention are as follows:

[0033] 1. This invention, through the setting of displacement sensors, sliding frames and other structures, when the lateral pressure of the track acts on the guide wheel body, the sliding frame moves along the sliding groove, the displacement sensor measures the displacement through the reflective end, and the control system quickly determines the direction and magnitude of the trolley's offset based on the difference between the two displacement sensors, actively adjusts the running posture, and responds promptly and accurately.

[0034] 2. The present invention uses a structure with forward ratchet and reverse ratchet, etc. When the drive motor rotates forward, it drives the conveying component to transport materials through the first transmission component. When it rotates in reverse, it drives the adjusting belt to run through the second transmission component. The friction force generated by the speed difference between the adjusting belt and the conveyor belt applies a lateral thrust to the material and adjusts the position of the material.

[0035] 3. The present invention uses a damping top block and a limiting sliding block to absorb high-frequency vibrations when the sliding frame moves and assist in resetting after the pressure disappears, thus maintaining stable contact between the guide wheel and the track; the limiting sliding block detects the conveyor belt deviation signal through the point contact electrode plate and sends a correction command to the control system in a timely manner to intervene in the deviation trend in advance.

[0057] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0058] Example

[0059] like Figures 1-11 As shown, a guide wheel mechanism for a cross-belt sorting machine trolley and its guiding method include a main frame 31;

[0060] Guide wheel mechanisms 3 are provided on both sides of the main frame 31. The guide wheel mechanism 3 consists of a guide wheel mounting beam 32 and two guide components 33. The guide wheel mounting beam 32 is fixedly connected to one side of the main frame 31 by bolts. The two guide components 33 are respectively installed at both ends of the guide wheel mounting beam 32. The guide components 33 are used to guide the movement of the trolley.

[0061] The guide assembly 33 consists of a guide wheel body 335 and a displacement sensor 338. There are at least two guide wheel bodies 335, which are slidably and rotatably installed inside the guide assembly 33. There are at least two displacement sensors 338, which are respectively installed on one side of the two guide wheels. The displacement sensors 338 are used to detect the amount of displacement of the guide wheels in real time.

[0062] A rotating component 2 is provided on the top of the main frame 31. The rotating component 2 is used to adjust the material conveying direction.

[0063] The top of the rotating component 2 is equipped with a conveying body 1. The conveying body 1 is equipped with a conveying component 13 and an adjusting component 14. The conveying component 13 is used to convey materials, and the adjusting component 14 is used to assist the conveying component 13 in adjusting the material conveying position.

[0064] A guide wheel mechanism 3 for a cross-belt sorting machine trolley uses a main frame 31 as the overall load-bearing foundation. Guide wheel mechanisms 3 are installed on both sides of the main frame 31. Each guide wheel mechanism 3 consists of a guide wheel mounting beam 32 and two guide components 33.

[0065] The guide wheel mounting beam 32 is rigidly fixed to the side of the main frame 31 by bolts. The two guide components 33 are respectively installed at both ends of the guide wheel mounting beam 32 to constrain and guide the travel direction of the trolley on the sorting machine track.

[0066] Each guide assembly 33 contains at least two guide wheel bodies 335 and at least two displacement sensors 338. The guide wheel bodies 335 are slidably and rotatably mounted inside the guide assembly 33. The guide wheel bodies 335 are mounted on the sliding component via a shaft and bearing structure. A sliding fit is formed between the sliding component and the housing of the guide assembly 33, so that the guide wheel bodies 335 can generate a small displacement in the radial direction when subjected to the lateral pressure of the track. At the same time, the outer circular surface of the guide wheel bodies 335 maintains rolling contact with the side of the track, converting sliding friction into rolling friction.

[0067] Displacement sensors 338 are respectively installed on one side of the two guide wheel bodies 335, forming a one-to-one detection relationship with the guide wheel bodies 335. The detection end of each displacement sensor 338 is directly opposite the reflection end 337 on the sliding component connected to the guide wheel body 335. When the guide wheel body 335 undergoes radial displacement, the sliding component drives the reflection end 337 to move synchronously. The displacement sensor 338 collects the amount of radial displacement of the guide wheel body 335 in real time by detecting the position change of the reflection end 337.

[0068] A rotating component 2 is installed on the top of the main frame 31. The rotating component 2 consists of a rotating frame 21 and a rotating disk 22. The rotating frame 21 is fixedly connected to the main frame 31. The rotating disk 22 rotates inside the rotating frame 21 through a slewing bearing, which can drive the upper structure to rotate and adjust in the horizontal direction.

[0069] The top of the rotating component 2 is fixedly installed with the conveying body 1. The conveying body 1 is equipped with a conveying component 13 and an adjusting component 14. The conveying component 13 is composed of multiple conveying shafts 131 and a conveyor belt 134. The conveying shafts 131 are linked by chain drive to realize the active transmission of materials.

[0070] The adjusting component 14 consists of multiple transmission shafts 141 and an adjusting belt 143. The adjusting belt 143 cooperates with the conveyor belt 134 in the conveying component 13. During actual operation, when the trolley runs along the track, the guide wheel body 335 in the guide wheel mechanism 3 contacts the side of the track. The displacement sensor 338 monitors the pressure displacement of the guide wheel in real time. The displacement signal is transmitted to the control system, and the control system determines the centering status of the trolley in the track based on the displacement. When it is necessary to change the output direction of the material, the rotating component 2 drives the rotating disk 22 to rotate, causing the conveying body 1 to turn as a whole, thereby adjusting the material conveying direction. During the conveying process, the adjusting component 14 works in conjunction with the conveying component 13 to fine-tune the lateral position of the material on the conveyor belt 134, ensuring that the material enters the next sorting stage with an accurate posture.

[0071] The guide wheel mounting beam 32 consists of a main beam 321, a limiting mounting side plate 322, and a connecting mounting plate 323. The main beam 321 is fixedly connected to one side of the main frame 31. The limiting mounting side plate 322 and the connecting mounting plate 323 are respectively set on both sides of the main beam 321. Both the limiting mounting side plate 322 and the connecting mounting plate 323 are connected to the main frame 31. Guide wheel mounting brackets 324 are provided at both ends of the main beam 321. The guide wheel mounting beam 32 is integrally formed.

[0072] The guide wheel mounting beam 32 adopts an integrally formed structure, consisting of a main beam 321, a limiting mounting side plate 322, and a connecting mounting plate 323. The main beam 321 serves as the main load-bearing component of the guide wheel mounting beam 32. It has an overall elongated structure. One side plane of the main beam 321 fits against the side of the main frame 31 and is fixedly connected to the main frame 31 by multiple bolts inserted into threaded holes on the main beam 321. The limiting mounting side plate 322 is set on one side of the main beam 321. The limiting mounting side plate 322 and the main beam 321 are integrally formed on the body. Its extension direction is perpendicular to the axis of the main beam 321. The surface of the limiting mounting side plate 322 forms a surface contact fit with the side edge of the main frame 31. During the assembly process, the limiting mounting side plate 322 is inserted into the limiting groove pre-processed on the side of the main frame 31, thereby restricting the degree of freedom of rotation of the guide wheel mounting beam 32 around the bolt axis during bolt tightening.

[0073] The connecting mounting plate 323 is located on the other side of the main beam 321. The connecting mounting plate 323 is also integrally formed with the main beam 321. The connecting mounting plate 323 extends vertically outward from the side of the main beam 321. The connecting mounting plate 323 has multiple mounting through holes. Bolts are passed through the mounting through holes to fasten the plate to the corresponding mounting surface of the main frame 31.

[0074] Guide wheel mounting brackets 324 are provided at both ends of the main beam 321. The guide wheel mounting brackets 324 are integrally formed with the main beam 321. Each guide wheel mounting bracket 324 is a hollow frame structure with an installation cavity for accommodating the guide component 33 inside. The inner wall of the installation cavity is provided with a machined sliding guide surface. Since the guide wheel mounting beam 32 is manufactured by an integral molding process, there are no splicing gaps or welding joints between the main beam 321, the limiting mounting side plate 322, the connecting mounting plate 323 and the guide wheel mounting brackets 324 at both ends, which ensures the relative positional accuracy between each mounting reference surface.

[0075] During actual assembly, the operator first aligns the limiting mounting side plate 322 with the limiting groove on the side of the main frame 31 and pushes it in, so that the mounting surface of the main beam 321 fits against the side of the main frame 31. Then, the bolt holes on the connecting mounting plate 323 are aligned with the threaded holes on the main frame 31, and the bolts are inserted and pre-tightened in sequence. Finally, the main mounting bolts on the main beam 321 are tightened to achieve multi-point rigid fixation of the guide wheel mounting beam 32 on the main frame 31.

[0076] The one-piece molded structure allows the guide components 33 installed in the guide wheel mounting brackets 324 at both ends to obtain a highly consistent installation reference, ensuring that the guide wheel mechanisms 3 on both sides of the trolley are subjected to uniform force when running on the track, thus improving the stability and synchronization of the guide.

[0077] The guide assembly 33 includes at least three sliding frames 331, which are symmetrically arranged and slidably mounted inside the guide wheel mounting frame 324. At least two symmetrically arranged damping blocks 332 are connected to the sliding frames 331 and the guide wheel mounting frame 324. A rotating shaft 333 is rotatably mounted inside the sliding frame 331. A guide wheel mounting frame 334 is movably fitted on the outer circumferential surface of the three rotating shafts 333. Two guide wheel bodies 335 are symmetrically arranged and rotatably mounted inside the guide wheel mounting frame 334.

[0078] The guide assembly 33 includes at least three sliding frames 331, which are symmetrically arranged and slidably mounted inside the guide wheel mounting frame 324. The guide wheel mounting frame 324 has a rectangular mounting cavity inside, and the inner wall of the mounting cavity is machined with a sliding groove extending in the radial direction. The three sliding frames 331 are respectively embedded in the sliding groove, with two sliding frames 331 symmetrically arranged on both sides of the mounting cavity and the third sliding frame 331 arranged in the middle of the mounting cavity. All three sliding frames 331 can slide freely in the radial direction within the sliding groove.

[0079] At least two symmetrically arranged damping blocks 332 are connected to the sliding frame 331 and the guide wheel mounting frame 324. One end of the damping block 332 is fixedly connected to the outer wall of the guide wheel mounting frame 324, and the other end passes through the shell of the guide wheel mounting frame 324 and contacts the side of the sliding frame 331. The damping block 332 is provided with elastic damping material inside, which is used to provide damping force when the sliding frame 331 generates radial displacement, suppress the vibration of the guide wheel body 335, and push the sliding frame 331 to reset when the lateral pressure of the track disappears.

[0080] Each sliding frame 331 has a rotating shaft 333 rotatably mounted inside. The rotating shaft 333 is supported in the inner hole of the sliding frame 331 by bearings. The axial direction of the rotating shaft 333 is perpendicular to the sliding direction of the sliding frame 331. A guide wheel mounting frame 334 is movably fitted on the outer circumferential surface of the three rotating shafts 333. The guide wheel mounting frame 334 has a rectangular frame structure. Its inner sidewall forms a sliding contact fit with the outer circumferential surface of the three rotating shafts 333. The guide wheel mounting frame 334 can be slightly slidably adjusted relative to the three rotating shafts 333 along the axial direction of the rotating shafts 333.

[0081] Two guide wheel bodies 335 are symmetrically arranged and rotatably installed inside the guide wheel mounting frame 334. Each guide wheel body 335 is installed at the end of the guide wheel mounting frame 334 via a wheel axle and a bearing. The outer circular surfaces of the two guide wheel bodies 335 face opposite directions and are used to contact the guide surfaces on both sides of the track.

[0082] When the trolley runs along the track, the side of the track applies pressure to the guide wheel body 335. The pressure is first transmitted to the guide wheel mounting frame 334, which then distributes the force to the three rotating shafts 333. The three rotating shafts 333 drive their respective sliding frames 331 to move along the sliding grooves in the guide wheel mounting frame 324. Since the three sliding frames 331 are symmetrically arranged, the lateral force on the guide wheel body 335 can be evenly transmitted to multiple support points of the guide wheel mounting frame 324, avoiding uneven loading caused by a single force point. At the same time, the damping block 332 continuously provides damping force during the movement of the sliding frame 331, absorbing high-frequency vibrations and ensuring that the guide wheel body 335 and the track always maintain a stable contact state.

[0083] The guide assembly 33 also includes two limiting slide plates 336, which are respectively installed on one side of two sliding frames 331 located on both sides. The limiting slide plates 336 are slidably assembled inside the guide wheel mounting frame 324. A reflective end 337 is fixedly connected to one side of the limiting slide plate 336. Two displacement sensors 338 are symmetrically arranged and installed on one side of the guide wheel mounting frame 324. The displacement sensors 338 are coaxial with the reflective end 337.

[0084] The guide assembly 33 also includes two limiting slide plates 336. The two limiting slide plates 336 are respectively installed on one side of the two sliding frames 331 located on both sides. The limiting slide plates 336 and the sliding frames 331 are fixedly connected by screws. The limiting slide plates 336 extend out from the side of the sliding frames 331 and have an overall elongated plate structure. The limiting slide plates 336 are slidably assembled inside the guide wheel mounting bracket 324. The guide wheel mounting bracket 324 has a through guide groove corresponding to the position of the limiting slide plates 336. The limiting slide plates 336 pass into the guide groove. The inner wall of the guide groove and the outer edge of the limiting slide plates 336 form a sliding fit. The limiting slide plates 336 can slide freely along the extension direction of the guide groove.

[0085] A reflective end 337 is fixedly connected to one side of the limiting slide plate 336. The reflective end 337 is made of a high reflectivity material, and its end face is perpendicular to the sliding direction of the limiting slide plate 336. Two displacement sensors 338 are symmetrically arranged and installed on one side of the guide wheel mounting bracket 324. Each displacement sensor 338 is a laser displacement sensor 338. The detection end face of the sensor faces the reflective end 337 on the limiting slide plate 336. The displacement sensor 338 and the reflective end 337 are coaxially arranged, that is, the axis of the detection beam emitted by the displacement sensor 338 coincides with the central axis of the reflective end 337.

[0086] When the guide wheel body 335 is subjected to lateral pressure from the track, the sliding frames 331 on both sides drive the limiting slide plate 336 to move synchronously. The reflective end 337 on the limiting slide plate 336 is displaced accordingly. The displacement sensor 338 emits a detection beam to the reflective end 337 in real time and receives the reflected light signal. By measuring the flight time or phase change of the beam, the change in distance between the reflective end 337 and the sensor is calculated, thereby measuring the radial displacement of the guide wheel body 335. Since the two displacement sensors 338 correspond to the two sliding frames 331 on both sides respectively, and the two sliding frames 331 on both sides correspond to the two guide wheel bodies 335 respectively, the system can independently detect the lateral pressure condition of each guide wheel body 335.

[0087] In actual operation, when the trolley passes through a curve in the track or when there is a joint in the track, the pressure on the two guide wheel bodies 335 may be different. The two displacement sensors 338 transmit the detected displacement signals to the signal acquisition module of the control system. The control system determines the direction and amount of the trolley's offset relative to the center line of the track by comparing the difference between the two displacement sensors 338. Then, it compensates for the offset by adjusting the steering angle of the rotating component 2 or the conveying speed of the conveying component 13, so as to ensure that the trolley's running trajectory on the sorting track is controllable.

[0088] The rotating component 2 consists of a rotating frame 21, which is fixedly connected to the top of the main frame 31. A rotating disk 22 is rotatably installed inside the rotating frame 21.

[0089] The rotating component 2 is composed of a rotating frame 21, which is fixedly connected to the top of the main frame 31.

The center of the rotating frame 21 coincides with the central axis of the main frame 31.

[0090] A rotating disk 22 is rotatably mounted inside the rotating frame 21. A slewing bearing is provided between the rotating disk 22 and the rotating frame 21. The inner ring of the slewing bearing is fixedly connected to the rotating disk 22, and the outer ring of the slewing bearing is fixedly connected to the rotating frame 21. Rolling elements are provided inside the slewing bearing so that the rotating disk 22 can achieve low-friction circumferential rotation inside the rotating frame 21.

[0091] The upper surface of the rotating disk 22 is a flat mounting plane with multiple threaded holes for connecting the conveying body 1. The rotating assembly 2 also includes a drive motor and a transmission mechanism. The drive motor is mounted on the main frame 31 or the rotating frame 21. The output end of the drive motor is connected to a drive gear. The drive gear meshes with a gear ring set on the outer circumference of the rotating disk 22. When it is necessary to adjust the material conveying direction, the control system sends a control command to the drive motor. The drive motor outputs rotational torque, the drive gear drives the gear ring to rotate, and the gear ring drives the rotating disk 22 to rotate around its own axis inside the rotating frame 21. The rotating disk 22 drives the conveying body 1 fixedly connected to it to rotate synchronously, thereby realizing the adjustment of the material conveying direction.

[0092] An angle encoder is also provided between the rotating disk 22 and the rotating frame 21. The stator part of the angle encoder is installed on the rotating frame 21, and the rotor part is installed on the rotating disk 22. It is used to detect the rotation angle of the rotating disk 22 in real time and feed it back to the control system to form a closed-loop control, so that the rotating component 2 can adjust the conveying body 1 to any required angle to meet the sorting requirements of the sorting system for the discharge port in different directions.

[0093] The conveying body 1 also includes a conveying box 11, which is installed on one side of the conveying body 1.

[0096] The second transmission assembly 123 consists of a second transmission shaft 1231 and a transmission main shaft 1235. The second transmission shaft 1231 is rotatably installed inside the power box 12. A reverse ratchet 1232 and a worm gear 1234 are respectively fixedly sleeved on the outer circumferential surface of the second transmission shaft 1231. A second meshing gear 1233 is movably sleeved on the outer circumferential surface of the second transmission shaft 1231.

[0097] A worm gear 1236 is fixedly sleeved on the outer circumferential surface of the transmission main shaft 1235, and the worm 1234 meshes with the worm gear 1236.

[0098] One side of the first meshing gear 1223 and the second meshing gear 1233 are connected by a torsion spring to several circumferentially distributed oscillating ratchet teeth, which respectively engage with the forward ratchet 1222 and the reverse ratchet 1232.

[0099] The main body 1 also includes a conveyor box 11, which is installed on one side of the main body 1. The conveyor box 11 is composed of a first transmission component 122, a second transmission component 123 and a power box 12. The power box 12 is equipped with a power component 121, which is used to provide power to the first transmission component 122 and the second transmission component 123. The power component 121 is composed of a drive motor 1211, which is installed on one side of the power box 12 via a motor mount. The output end of the drive motor 1211 is equipped with a rotating shaft 1212 via a coupling. The rotating shaft 1212 is horizontally arranged inside the power box 12, and a transmission gear 1213 is fixedly sleeved on the outer periphery of the rotating shaft 1212.

[0100] The first transmission assembly 122 is composed of a first transmission shaft 1221. The first transmission shaft 1221 is rotatably mounted inside the power box 12 via bearings. A forward ratchet 1222 is fixedly sleeved on the first transmission shaft 1221. A first meshing gear 1223 is also movably sleeved on the first transmission shaft 1221. The first meshing gear 1223 meshes with the transmission gear 1213.

[0101] The second transmission assembly 123 consists of a second transmission shaft 1231 and a main transmission shaft 1235. The second transmission shaft 1231 is rotatably mounted inside the power box 12 via bearings. A reverse ratchet 1232 and a worm gear 1234 are fixedly sleeved on the outer circumferential surface of the second transmission shaft 1231. A second meshing gear 1233 is movably sleeved on the outer circumferential surface of the second transmission shaft 1231, and the second meshing gear 1233 also meshes with the transmission gear 1213. The main transmission shaft 1235 is rotatably mounted inside the transmission box 11 via bearings. A worm gear 1236 is fixedly sleeved on the outer circumferential surface of the main transmission shaft 1235. The worm gear 1234 and the worm gear 1236 mesh with each other to form a worm gear 1236-worm gear 1234 transmission pair. The first meshing gear 1223 and the second meshing gear 1233... One side of each gear 1221 is connected by a torsion spring to several circumferentially distributed ratchet teeth. The ratchet teeth on the first meshing gear 1223 engage with the forward ratchet 1222, and the ratchet teeth on the second meshing gear 1233 engage with the reverse ratchet 1232. When the drive motor 1211 rotates in the forward direction, the drive gear 1213 drives the first meshing gear 1223 and the second meshing gear 1233 to rotate synchronously in the forward direction. At this time, the ratchet teeth on the first meshing gear 1223 engage with the forward ratchet 1222 under the action of the torsion spring, driving the first drive shaft 1221 to rotate in the forward direction. Meanwhile, the ratchet teeth on the second meshing gear 1233 slide relative to the tooth surface of the reverse ratchet 1232 when rotating in the forward direction, and cannot drive the second drive shaft 1231 to rotate, thereby realizing the function of the first transmission component 122 outputting power independently.

[0102] When the drive motor 1211 rotates in the reverse direction, the drive gear 1213 drives the first meshing gear 1223 and the second meshing gear 1233 to rotate synchronously in the opposite direction. At this time, the ratchet on the first meshing gear 1223 slides relative to the forward ratchet 1222, and cannot drive the first drive shaft 1221 to rotate. However, the ratchet on the second meshing gear 1233 engages with the reverse ratchet 1232 when rotating in the reverse direction, driving the second drive shaft 1231 to rotate in the opposite direction. The second drive shaft 1231 drives the worm wheel 1236 to rotate through the worm gear 1234, which in turn drives the main drive shaft 1235 to rotate. Through this unidirectional ratchet transmission structure, a single drive motor 1211 can selectively drive the first transmission component 122 or the second transmission component 123 to work, realizing independent control of the conveying component 13 and the adjusting component 14.

[0103] The conveying assembly 13 consists of several conveying shafts 131, which are rotatably installed inside the conveying box 11 in an equidistant distribution. One of the conveying shafts 131 is fixedly connected to the first drive shaft 1221, and several equidistant conveying rollers 132 are fixedly sleeved on the conveying shaft 131.

[0104] The conveying roller 132 is composed of a roller body 1321, which is connected to the conveying shaft 131. A friction conveying surface 1322 is fixedly sleeved on the outer circumferential surface of the roller body 1321. A conveying belt 134 is sleeved on the conveying rollers 132 located on the same axis. Conveying sprockets 133 are fixedly sleeved on both ends of the conveying shaft 131. A conveying chain belt 135 is sleeved on the conveying sprockets 133 located on the same side.

[0105] The conveyor roller 132 has several circumferentially distributed connecting inner grooves 1323 on both sides. The connecting inner grooves 1323 are slidably fitted with limiting sliding blocks 1324. Two symmetrically arranged damping elastic blocks 1325 are arranged at the axial position of the limiting sliding block 1324. Two symmetrically arranged point contact electrode plates 1326 are arranged at the bottom of both sides of the limiting sliding block 1324.

[0106] The conveying assembly 13 consists of several conveying shafts 131, which are rotatably installed inside the conveying box 11 at equal intervals. The two ends of the conveying shafts 131 are supported on the side wall of the conveying box 11 by bearings. One of the conveying shafts 131 is fixedly connected to the first drive shaft 1221. The conveying shaft 131 serves as the drive shaft and obtains power input through the first drive shaft 1221.

[0107] Several equidistantly distributed conveyor rollers 132 are fixedly sleeved on each conveyor shaft 131. The conveyor rollers 132 rotate synchronously with the conveyor shaft 131. The conveyor rollers 132 are composed of roller bodies 1321. The roller bodies 1321 are cylindrical in shape. The inner hole of the roller body 1321 is connected to the conveyor shaft 131 by a key to form a circumferential fixation. A friction conveying surface 1322 is fixedly sleeved on the outer circumferential surface of the roller body 1321. The friction conveying surface 1322 is made of an elastic material with a high coefficient of friction to increase the friction between the roller body 134 and the conveyor belt 134.

[0108] A conveyor belt 134 is fitted on all the conveyor rollers 132 on the same axis. The conveyor belt 134 has a ring structure and its inner surface is in close contact with the friction conveying surface 1322 of the conveyor rollers 132. Both ends of the conveyor shaft 131 are fixedly fitted with conveyor sprockets 133. A conveyor chain belt 135 is fitted on all the conveyor sprockets 133 on the same side. The conveyor chain belt 135 connects multiple conveyor shafts 131 in series to form a chain drive, so that all the conveyor shafts 131 can rotate synchronously.

[0109] The conveyor roller 132 has several circumferentially distributed connecting inner grooves 1323 on both sides. The connecting inner grooves 1323 are recessed inward along the radial direction of the conveyor roller 132. Each connecting inner groove 1323 is slidably fitted with a limiting sliding block 1324. The limiting sliding block 1324 can slide in the connecting inner groove 1323 along the axial direction of the conveyor roller 132. Two symmetrically arranged damping elastic blocks 1325 are arranged at the axial position of the axis of the limiting sliding block 1324. One end of the damping elastic block 1325 is fixedly connected to the limiting sliding block 1324, and the other end contacts the bottom surface of the connecting inner groove 1323 to provide damping force when the limiting sliding block 1324 slides.

[0110] Two symmetrically arranged point contact electrode plates 1326 are provided on both sides of the bottom of the limiting sliding block 1324. The point contact electrode plates 1326 are connected to the circuit inside the conveying roller 132. When the conveyor belt 134 runs on the conveying roller 132, the two sides of the conveyor belt 134 contact the limiting sliding block 1324, pushing the limiting sliding block 1324 to slide along the connecting inner groove 1323 into the interior of the conveying roller 132.

[0111] When the conveyor belt 134 deviates from its designated path, the pressure on the limiting sliding block 1324 increases on one side edge of the conveyor belt 134, pushing the limiting sliding block 1324 further into the connecting inner groove 1323. The point contact electrode 1326 at the bottom of the limiting sliding block 1324 moves accordingly. When the deviation reaches a set threshold, the point contact electrode 1326 connects with the fixed contact inside the connecting inner groove 1323, generating an electrical signal. The signal is transmitted to the control system, which determines the direction of the conveyor belt 134's deviation and issues a correction command.

[0112] The adjustment assembly 14 consists of several transmission shafts 141 and transmission rollers 142. The several transmission shafts 141 are rotatably installed inside the conveyor box 11 in pairs, staggered and equidistantly distributed. The several transmission rollers 142 are fixedly sleeved on the outer circumference of the transmission shafts 141 in equidistant distribution. Two main transmission shafts 1235 are rotatably installed inside the conveyor box 11 in a symmetrical arrangement. An adjustment belt 143 is movably sleeved on both the main transmission shafts 1235 and the transmission rollers 142.

[0113] The adjustment assembly 14 consists of several transmission shafts 141 and transmission rollers 142. The several transmission shafts 141 are rotatably installed inside the conveyor box 11 in pairs, which are staggered and equidistant from each other. The transmission shafts 141 are arranged in two layers, with the upper and lower transmission shafts 141 offset from each other in the horizontal projection direction. The transmission shafts 141 in each layer are equidistant from each other. The two ends of the transmission shafts 141 are supported on the side wall of the conveyor box 11 by bearings. Several transmission rollers 142 are fixedly sleeved on the outer circumference of the transmission shafts 141 in a equidistant arrangement. Each transmission roller 142 rotates synchronously with the corresponding transmission shaft 141. Two main transmission shafts 1235 are rotatably installed inside the conveyor box 11 in a symmetrical arrangement. One end of the main transmission shaft 1235 is fixedly connected to the worm gear 1236 as described in claim 6, and obtains rotational power through the worm gear 1236 and worm 1234 transmission pair.

[0114] An adjusting belt 143 is movably fitted onto both the transmission main shaft 1235 and the transmission roller 142. The adjusting belt 143 has a ring structure, and its inner surface forms a frictional transmission engagement with the outer circumferential surfaces of the transmission main shaft 1235 and the transmission roller 142. When the control system needs to adjust the lateral position of the material on the conveying assembly 13, it controls the transmission motor 1211 to rotate in the opposite direction. The power is transmitted to the transmission main shaft 1235 through the second transmission assembly 123. The transmission main shaft 1235 drives the adjusting belt 143 to run. Since the transmission shaft 141 is arranged in an alternating vertical arrangement, the adjusting belt 143 forms a wave under the support of the transmission roller 142. The wavy running trajectory allows the outer surface of the adjusting belt 143 to contact the bottom edge of the material on the conveyor belt 134 in the conveying assembly 13. The friction generated by the speed difference between the running direction of the adjusting belt 143 and the running direction of the conveyor belt 134 applies a lateral thrust to the material, causing the material to move laterally on the conveyor belt 134. When the material moves to the preset position, the control system stops the operation of the adjusting assembly 14 according to the feedback signal from the position sensor. By independently controlling the rotation direction and speed of the two drive shafts 1235, the material can be adjusted to the left or right, ensuring that the material is in an accurate centering position before entering the sorting port.

[0115] Guiding method of guide wheel mechanism of cross belt sorting machine trolley;

[0116] S1: The guide wheel mechanism 3 is fixedly installed on both sides of the main frame 31 via the guide wheel mounting beam 32, and the guide wheel body 335 in the guide assembly 33 is in contact with the sorting machine track.

[0117] S2: Start the sorting machine. The trolley runs along the track, and the guide wheel body 335 rolls on the track to guide the trolley's running direction.

[0118] S3: During the guiding process, the displacement sensor 338 detects the radial displacement of the guide wheel body 335 in real time due to uneven track or wear of the guide wheel, and outputs the displacement signal to the external control system.

[0119] S4: The external control system determines the wear level of the guide wheel body 335 or the flatness of the track based on the received displacement signal.

[0120] The external control system compares the received displacement signal with a preset threshold: when the displacement exceeds the preset threshold, it issues an alarm signal to replace the guide wheel or repair the track.

[0121] When the displacement is within the preset threshold, the trolley continues to operate normally.

[0122] Working principle: When the trolley moves along the sorting track, the guide wheel mechanism 3 set on both sides of the main frame 31 starts to work. In each guide wheel mechanism 3, the guide wheel mounting beam 32, which is rigidly fixed to one side of the main frame 31 by bolts, is an integrally formed structure. Its main beam 321, limiting mounting side plate 322 and connecting mounting plate 323 together ensure the accuracy of the mounting reference surface. The guide wheel mounting frame 324 located at both ends of the main beam 321 forms a mounting cavity inside.

[0123] The guide assembly 33, which is installed in the guide wheel mounting bracket 324, has three symmetrically arranged sliding brackets 331 embedded in the sliding grooves on the inner wall of the mounting cavity, which can slide freely in the radial direction; the symmetrically arranged damping top blocks 332 connecting the sliding brackets 331 and the guide wheel mounting bracket 324 are provided with elastic damping material inside, which provides damping force and assists in resetting.

[0124] Inside each sliding frame 331, a rotating shaft 333 is rotatably mounted via a bearing. A guide wheel mounting frame 334 is movably fitted on the outer circumferential surface of the three rotating shafts 333. Two guide wheel bodies 335 are symmetrically arranged and rotatably mounted on the end of the guide wheel mounting frame 334, and their outer circular surfaces maintain rolling contact with the guide surfaces on both sides of the track.

[0125] When the lateral pressure of the track acts on the guide wheel body 335, the pressure is distributed and transmitted to the three rotating shafts 333 through the guide wheel mounting frame 334, driving the respective sliding frame 331 to move along the sliding groove. The damping top block 332 absorbs high-frequency vibration during this process. The limiting slide plate 336 located on one side of the sliding frame 331 on both sides is fixedly connected by screws and slidably assembled in the guide groove of the guide wheel mounting frame 324. The reflective end 337 fixed on the limiting slide plate 336 is coaxially set with the displacement sensor 338 installed on one side of the guide wheel mounting frame 324. The displacement sensor 338 adopts the laser principle and emits a detection beam to the reflective end 337 in real time. By receiving the reflected light signal, the radial displacement of the guide wheel body 335 is measured. The two displacement sensors 338 independently detect the pressure of the two guide wheel bodies 335 and transmit the displacement signal to the control system.

[0126] The control system compares the difference between two displacement sensors 338 to determine the direction and amount of the trolley's offset relative to the center line of the track, and then issues an adjustment command. When it is necessary to change the material conveying direction, the rotating component 2 installed on the top of the main frame 31 starts to move. The rotating frame 21 is fixedly connected to the main frame 31, and the rotating disk 22 inside it rotates through the slewing bearing. The drive motor meshes with the gear ring on the outer circumference of the rotating disk 22 through the drive gear, driving the rotating disk 22 to rotate. At the same time, the angle encoder provides real-time feedback of the rotation angle to form a closed-loop control, causing the conveying body 1 fixed on the top of the rotating disk 22 to turn.

[0127] Inside the conveyor box 11 of the main conveyor 1, the power assembly 121 in the power box 12 provides power. The output end of the drive motor 1211 is fixedly sleeved with the drive gear 1213 through the rotating shaft 1212, and simultaneously meshes with the first meshing gear 1223 of the first drive assembly 122 and the second meshing gear 1233 of the second drive assembly 123. When the drive motor 1211 rotates in the forward direction, the ratchet on the first meshing gear 1223 engages with the forward ratchet 1222 on the first drive shaft 1221 under the action of the torsion spring, driving the first drive shaft 1221 to rotate in the forward direction. Meanwhile, the ratchet on the second meshing gear 1233 slides relative to the reverse ratchet 1232 on the second drive shaft 1231 and does not transmit power, thereby realizing the independent drive of the conveyor assembly 13.

[0128] When the drive motor 1211 rotates in the reverse direction, the first meshing gear 1223 slides relative to the forward ratchet 1222, and the ratchet on the second meshing gear 1233 engages with the reverse ratchet 1232, driving the second drive shaft 1231 to rotate in the reverse direction. The second drive shaft 1231 drives the worm wheel 1236 on the drive main shaft 1235 to rotate through the worm 1234, thereby realizing the independent drive of the adjustment component 14.

[0129] In the conveying assembly 13, the conveying shaft 131, which is fixedly connected to the first drive shaft 1221, serves as the drive shaft. The synchronous rotation of all conveying shafts 131 is achieved through the conveying sprockets 133 fixedly sleeved at both ends of the conveying shaft 131 and the conveying chain belt 135 that is sleeved together. The conveying roller 132 fixedly sleeved on each conveying shaft 131 consists of a roller body 1321 and a friction conveying surface 1322 on the outer circumference. The conveying belt 134 that is sleeved together on the conveying roller 132 on the same axis runs accordingly to actively transport materials.

[0130] Limiting sliding blocks 1324 are slidably assembled in the connecting inner grooves 1323 on both sides of the conveying roller 132. Two symmetrically arranged damping elastic blocks 1325 are provided at the axial position of the axis of the limiting sliding block 1324. The point contact electrode plates 1326 provided at the bottom of both sides are connected to the internal circuit of the conveying roller 132.

[0131] When the material deviates on the conveyor belt 134, the pressure of the limiting sliding block 1324 on one side edge increases, pushing it to slide so that the point contact electrode 1326 connects with the fixed contact, generating an electrical signal that is transmitted to the control system and issuing a correction command. In the adjustment assembly 14, the transmission shafts 141, which are arranged in pairs and are equidistantly distributed, are rotatably installed inside the conveyor box 11. The transmission shafts 141 are fixedly sleeved with equidistantly distributed transmission rollers 142. The two symmetrically arranged transmission main shafts 1235 and the transmission rollers 142 are movably sleeved together with the adjustment belt 143.

[0132] When the control system needs to adjust the lateral position of the material, the control drive motor 1211 rotates in the opposite direction, and the power is transmitted to the drive main shaft 1235 through the second transmission component 123. The drive main shaft 1235 drives the adjustment belt 143 to run. Since the transmission shaft 141 is arranged in an alternating manner, the adjustment belt 143 forms a wave-shaped running trajectory under the support of the drive roller 142. Its outer surface contacts the bottom edge of the material on the conveyor belt 134. The friction generated by the speed difference between the adjustment belt 143 and the conveyor belt 134 applies a lateral thrust to the material. By independently controlling the rotation direction and speed of the two drive main shafts 1235, the material can be adjusted to the left or right to ensure that the material enters the next sorting stage with an accurate centering posture.

[0133] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
