Description

Technical Field

[0001] This utility model relates to the field of sorting equipment technology, and in particular to a drive device for a tipping sorting device. Background Technology

[0002] In logistics, warehousing, and manufacturing, sorting of various items is often required. As a highly efficient sorting device, the tipping bucket device is widely used in these scenarios. Its main function is to use the tipping mechanism to tilt the items placed in the tipping bucket to a designated location, thereby achieving the sorting and classification of items.

[0003] Existing technologies for driving the synchronous operation of the two rollers in a tipping device generally employ an indirect transmission structure consisting of a motor, toothed belt / chain, and synchronous pulley. This transmission chain is lengthy and prone to failure. Power is transmitted through multiple stages: the motor output shaft, synchronous pulley, toothed belt / chain, driven pulley, and rollers. Wear on the toothed belt teeth, eccentricity of the synchronous pulley, and chain jamming can all lead to transmission failure. Furthermore, after prolonged operation, the toothed belt is prone to stretching and deformation, causing tooth skipping and resulting in asynchronous rotation of the two rollers, leading to jamming or deviation of the tipping mechanism. Moreover, the toothed belt / chain transmission... The installation requires extremely high coaxiality and parallelism; chain drives require precise adjustment of the center distance between the two sprockets, otherwise it is easy to get stuck due to excessive tightness or to drop the chain due to excessive looseness, resulting in a long adjustment cycle. Moreover, traditional tensioning structures are cumbersome and prone to failure. To solve the problem of loose toothed belts / chains, existing technologies require the addition of complex tensioning components such as tensioning wheels or adjusting screws. The tensioning wheels need to be manually adjusted regularly, and the springs are prone to fatigue failure due to long-term stress, resulting in a sharp drop in tension and further aggravating the wear of transmission components. On average, the tensioning components need to be replaced every 3 months, resulting in a high maintenance frequency. Utility Model Content

[0004] The main objective of this invention is to provide a driving device for a tipping sorting device to solve the problems mentioned in the background art.

[0005] The drive unit includes a motor housing and a first motor and a second motor installed inside the motor housing. The first motor drives a first roller, and the second motor drives a second roller. A gap is formed between the first roller and the second roller to allow a contact plate to pass through. The drive unit also includes: A first mounting plate is provided, and a first motor is mounted on the first mounting plate. A first guide block is provided on the edge of the first mounting plate, and a hook is provided on the first guide block. The second mounting plate is used to mount the second motor. The edge of the second mounting plate is provided with a second guide block, and the second guide block is provided with a hook. The first guide block of the first mounting plate and the second guide block of the second mounting plate are both set in the guide groove on the mounting side plate of the motor box, and the first guide block and the second guide block are held together by a spring between two hooks.

[0006] In this technical solution, the direct-drive design eliminates indirect transmission losses. A spring tensioning mechanism, in conjunction with guide blocks, ensures stable friction, making it suitable for long-term operation. The spring automatically compensates for wear, maintaining a stable driving force. The hooks of the first and second guide blocks are tensioned by a spring, ensuring that the first and second mounting plates are always subjected to opposing preload. This preload is transmitted to the first and second rollers, ensuring that the two rollers always maintain a tight contact with the plate surfaces. When the rollers wear due to long-term friction, the spring automatically retracts, moving the mounting plate along the guide groove to compensate for the wear. Preferably, the motor box includes two mounting side plates arranged opposite each other, with a first mounting plate and a second mounting plate both installed between the two mounting side plates. The first mounting plate has a first guide block on both sides and a motor mounting hole on the first mounting plate. The first motor is installed in the motor mounting hole. The second mounting plate is symmetrical to the first mounting plate in structure.

[0007] The first mounting plate adopts a double-sided guide and precise positioning structure. The left and right sides are integrally formed with first guide blocks, which are adapted to the guide grooves on the inner wall of the mounting side plate. The center has a motor mounting hole that matches the outer diameter of the first motor. The first motor is embedded in the motor mounting hole and rigidly fixed to the mounting plate by bolts. The second mounting plate is completely symmetrical to the structure of the first mounting plate. The two sides are provided with second guide blocks, and the center has a motor mounting hole of the same specification. The second motor is embedded and installed accordingly. The two mounting plates are slidably placed between the two mounting side plates through the double-sided guide blocks, and together with the spring tensioning assembly, they form a symmetrical dual-drive unit.

[0008] Preferably, the output shaft of the first motor is directly fitted with a transmission gear, and the first roller has a mounting hole into which the transmission gear is inserted; the second motor has the same structure as the first motor.

[0009] This technical solution adopts a direct drive mode in which the first motor directly drives the first roller and the second motor directly drives the second roller. Compared with the indirect transmission of existing technologies using motors, toothed belts / chains, and synchronous pulleys, it eliminates multiple intermediate transmission components and improves the accuracy and reliability of transmission.

[0010] Preferably, both mounting side plates are provided with flanges, and the drive device is fixed to the bottom side of the slide rail through the flanges. The first roller and the second roller are matched with the contact plate of the tipping mechanism on the slide rail.

[0011] Both mounting side plates of the drive mechanism adopt a flanged reinforcement structure. The bottom edge of each mounting side plate extends outward to form a horizontal flange. The flange has evenly distributed mounting holes with the hole diameter matching the threaded hole on the bottom side of the slide rail. The drive device fits against the bottom side of the slide rail through the flange, and the bolt passes through the mounting hole of the flange to connect with the slide rail thread, so as to achieve rigid fixation between the drive mechanism and the slide rail. Meanwhile, the first roller and the second roller adopt a contact plate matching design, and the gap between the two rollers is precisely matched to the thickness of the contact plate, ensuring that the contact plate can pass smoothly through the gap between the rollers. At the same time, the rollers and the contact plate maintain surface contact to form a stable friction force transmission.

[0012] Other beneficial effects of this invention are further illustrated in the specific embodiments. Attached Figure Description

[0021] The following embodiments will provide a detailed description of a sorting tipping device of this application.

[0022] This embodiment discloses a tipping bucket device suitable for material sorting scenarios. Through modular design, it achieves stable material conveying, accurate detection, and low-impact sorting. Its structure is as follows: Sorting device The sorting device has a circular conveyor path 3, forming a closed-loop sorting system. Figure 1 The diagram shows a partial structure of a circular conveying path. Multiple tipping mechanisms 5 are arranged sequentially on a circular slide rail 3. At least one pushing mechanism 6 is fixed on one side of the slide rail 3 to trigger the tipping mechanism to tilt. A driving device 4 is fixed on the bottom side of the slide rail 3 for the movement of the aforementioned multiple tipping mechanisms, forming a collaborative system of driving, conveying, detection, and sorting. The driving device 4 drives the tipping mechanism 5 to move cyclically along the circular slide rail 3 through friction. When the sorting operation is triggered, the tipping mechanism 5 moves to the preset sorting station. The pushing mechanism 6 cooperates with the clamping plate 504 of the tipping mechanism 5 to trigger the pallet 512 to tilt and achieve material sorting. The overall structure is compact and the sorting efficiency is high. The circular slide rail design can realize continuous batch sorting. tipping mechanism See Figure 3 and Figure 4The tipping mechanism 5 includes a trolley assembly and a mounting frame. The trolley assembly includes a base 1, a set of sliding wheels 2, and a contact plate 401. The mounting frame includes a vertical support frame 501 and a horizontal connecting frame 502. The mounting frame is fixed to the top surface of the base 1. The trolley assembly slides in conjunction with the annular slide rail 3 through the set of sliding wheels 2. The contact plate 401 on the bottom surface of the base 1 contacts the rollers of the drive device 4, providing a power transmission interface for the movement of the tipping mechanism 5. The tipping mechanism 5 includes a tipping plate 509 and a locking plate 504. The tipping plate 509 is rotatably mounted horizontally on the top of the support frame 501. Its first end can be locked into the locking groove 505 of the locking plate 504, achieving the initial positioning of the tipping plate in the locking position. The second end drives the tray to tilt with the tipping action. The locking plate 504 is rotatably mounted vertically on the first end of the connecting frame 502. Its lower end is integrally formed with an inclined plate 506. The inclined plate 506 protrudes at an angle away from the connecting frame 502, serving as a trigger interface for cooperation with the pushing mechanism 6. When the locking plate 504 is deflected by the force of the pushing mechanism 6, the locking groove 505 disengages from the first end of the tipping plate 509, releasing the rotation constraint of the tipping plate.

[0023] like Figures 1-5 As shown, in this embodiment, two sets of locking blocks are provided on one side surface of the flip plate 509, and two sets of locking slots 505 are provided on the surface of the locking plate 504. The inner dimensions of the locking slots 505 match the outer dimensions of the locking blocks. With the above structure, in the initial state during use, the two sets of locking blocks of the flip plate 509 are respectively embedded in the two sets of locking slots 505 of the locking plate 504. Through the tight cooperation between the locking blocks and the locking slots 505, a double locking structure is formed, restricting the rotation of the flip plate 509. When the locking plate 504 tilts around the first rotating shaft 503... At this time, the card slot 505 rotates synchronously with the card plate 504, and the fit between the card slot 505 and the card block gradually loosens until the card block completely disengages from the card slot 505, releasing the lock on the flip plate 509. The dual locking design of the two sets of card blocks and card slots 505 significantly improves the stability and reliability of the flip plate 509 lock compared to a single set of locks, preventing the lock from failing due to vibration during movement and preventing the flip plate 509 from accidentally flipping. The card slot 505 and the card block are sized to match, ensuring a tight fit and making the unlocking process smoother. That is, the tipping mechanism 5 includes a support frame 501, which is fixedly connected to the top of the base 1. A connecting plate 502 is fixedly connected to the middle of the support frame 501. A locking plate 504 is rotatably connected to the connecting plate 502 through a first rotating shaft 503. A locking groove 505 is opened on the surface of the locking plate 504. An inclined plate 506 is connected to the surface of the locking plate 504. A flipping plate 509 is rotatably connected to the support frame 501 through a second rotating shaft 508. In the initial state, the locking plate 504 locks the flipping plate 509 through the locking groove 505 to prevent it from flipping randomly. When the inclined plate 506 is subjected to external force, it will drive the locking plate 504 to rotate around the first rotating shaft 503, so that the locking groove 505 is disengaged from the flipping plate 509. At this time, the flipping plate 509 can rotate around the second rotating shaft 508 to realize the tipping and sorting of items.

[0024] In some scenarios, a weight sensor 511 is fixed to the top surface of the flipping plate 509, and a tray 512 is fixed to the top surface of the weight sensor 511, forming a rigid load-bearing chain of the flipping plate, the weight sensor, and the tray. This not only enables material weight detection but also ensures that the tray moves synchronously with the flipping plate. If it is not necessary to detect the weight of the items, the weight sensor 511 can be omitted from the tipping mechanism 5.

[0025] Promotion agencies The driving mechanism is the trigger component for tipping the bucket. It adopts a fixed installation and stable driving design, which solves the problems of difficult wiring and large impact in the existing technology. The pushing mechanism 6 includes a fixed base 601 and a housing 602. The fixed base 601 is fixed to the preset working position side of the annular slide rail 3 by bolts, and the housing 602 is fixed to the top surface of the fixed base 601, forming a closed chamber to protect the internal components, while providing an installation reference for the electric push rod 605. An electric push rod 605 is fixed inside the outer casing 602. The electric push rod 605 is essentially an electromagnet. When energized, the push rod extends and when de-energized, it retracts. The extended end of the electric push rod 605 is fixed to a fixing plate 606. A push pulley 607 is bolted to one side of the fixing plate 606. The push pulley 607 can reduce frictional loss with the clamping plate 506. A stabilizing rod 608 is fixed in parallel on the other side of the fixing plate. The stabilizing rod 608 passes through the guide hole of the limiting block 609. The limiting block 609 is fixed to the inner wall of the outer casing 602, forming a guiding system of electric push rod, stabilizing rod and limiting block, preventing radial sway when the electric push rod 605 extends and retracts, and ensuring stable contact between the push pulley 607 and the clamping plate 506. When it is necessary to unlock the tipping mechanism 5, the electric push rod 605 is energized and activated, pushing the fixed plate 606 to move closer to the tipping mechanism 5. The fixed plate 606 drives the push pulley 607 to move synchronously, so that the push pulley 607 is pushed out to the designated position in advance. When the inclined plate 506 of the tipping mechanism 5 moves to contact the push pulley 607, the push pulley 607 rolls and cooperates with the inclined plate 506 to apply force to the inclined plate 506, so as to realize the tilting and unlocking of the locking plate 504. The outer shell 602 protects the internal components such as the electric push rod 605.

[0026] In this embodiment, a stabilizing rod 608 is fixedly connected to one side surface of the fixed plate 606, and a limiting block 609 is slidably connected to the outer surface of the stabilizing rod 608. With this structure, during use, when the electric push rod 605 pushes the fixed plate 606 to move, the fixed plate 606 will drive the stabilizing rod 608 to move synchronously. Since the stabilizing rod 608 is slidably connected to the limiting block 609, the limiting block 609 restricts the movement trajectory of the stabilizing rod 608, preventing the stabilizing rod 608 from bending or shifting during movement; the stabilizing rod 608 then... The movable fixed plate 606 maintains stable movement, preventing tilting of the fixed plate 606 from causing positional deviation of the push pulley 607. The cooperation between the stabilizer bar 608 and the limit block 609 significantly improves the stability and accuracy of the movement of the fixed plate 606 and the push pulley 607, ensuring that the push pulley 607 can accurately contact the inclined plate 506 of the tipping mechanism 5, avoiding unlocking failure due to positional deviation. The stabilizer bar 608 can also share the lateral force on the electric push rod 605, preventing damage to the electric push rod 605 due to uneven force, and extending the service life of the electric push rod 605.

[0027] like Figures 1-5As shown, in this embodiment, four sets of mounting blocks 603 are fixedly connected to the upper surface of the outer shell 602, and a cover 604 is slidably connected to the upper surface of the outer shell 602. With this structure, during use, the four sets of mounting blocks 603 are evenly distributed above the outer shell 602, providing a sliding track for the cover 604. When it is necessary to inspect or maintain the internal components of the outer shell 602, the operator can push the cover 604 along the extension direction of the mounting blocks 603, causing the cover 604 to slide open relative to the outer shell 602, exposing the internal components. After the inspection is completed, the cover 604 can be pushed back to its original position, restoring its position above the outer shell 602. The sliding connection design of the cover 604, compared to traditional bolt-fixed covers, allows for opening and closing without disassembling the bolts, making operation more convenient and significantly shortening inspection and maintenance time. The four sets of mounting blocks 603 ensure the stability of the cover 604 during sliding, preventing the cover 604 from shifting or falling off.

[0028] When sorting is required, the electric push rod 605 is energized in advance and extends, pushing the pulley 607 to the contact position. During the movement of the tipping mechanism 5 along the slide rail 3 towards the pushing mechanism 6, the inclined plate 506 of the clamping plate 504 first contacts the pushing pulley 607. As the tipping mechanism continues to move, the pushing pulley 607 slides along the inclined surface of the inclined plate 506, applying a force perpendicular to the inclined surface to the inclined plate. This force is decomposed into a torque that drives the clamping plate 504 to slowly deflect around the rotation axis. Compared with the "instantaneous impact triggering" of the prior art, this structure achieves the slow rotation of the clamping plate through inclined surface contact, which can reduce the impact on the tipping mechanism 5. To mitigate the impact load and extend the service life of moving components such as the base 1 and the sliding wheel assembly 2, the electric push rod 605 of the pushing mechanism 6 extends in advance, pushing the pulley 607 to form an inclined surface contact with the inclined plate 506 of the clamping plate 504. The kinetic energy of the tipping mechanism 5 is converted into the mechanical energy of the clamping plate's deflection, achieving a slow rotation of the clamping plate. When the clamping slot 505 disengages from the tipping plate 509, the tipping plate naturally tilts to the side under the action of gravity torque. At the same time, the pushing mechanism 6 is fixed on the slide rail 3 and does not move with the tipping mechanism. The power wiring can be directly laid along the slide rail 3, solving the problem of difficult wiring when the tipping mechanism moves in the prior art. The connecting frame 502 has a first stop 507 at its second end, and a second stop 510 on the bottom surface of the tilting plate 509. When the tray 512 tilts, the first stop 507 and the second stop 510 rigidly contact each other, mechanically limiting the tilting angle of the tilting plate 509 within a preset range. The mechanical limiting of the first stop 507 and the second stop 510 prevents excessive tilting, reducing impact and ensuring sorting stability. Figures 1-5As shown, in this embodiment, a first stop 507 is fixedly connected to one side surface of the support frame 501, and a second stop 510 is fixedly connected to the lower surface of the flip plate 509. With the above structure, when the flip plate 509 flips around the second pivot 508 to tilt the items, the flip plate 509 will drive the second stop 510 to rotate synchronously. When the flip plate 509 flips to a specified angle, the second stop 510 will contact the first stop 507 on the support frame 501. The first stop 507 generates a blocking force on the second stop 510, restricting the flip plate 509 from continuing to rotate. The cooperation between the first stop 507 and the second stop 510 effectively limits the maximum flip angle of the flip plate 509, avoiding excessive tilting of items and deviation from the designated sorting area due to excessive flip angle, while also preventing the flip plate 509 from colliding and being damaged by other components.

[0029] Drive structure The drive structure 4 provides the moving power for the tipping mechanism 5. It includes a motor box, two oppositely arranged mounting side plates 406 and other frame plates. The top of the mounting side plates 406 is provided with flanges. The drive device 4 is fixed to the bottom side of the annular slide rail 3 by bolts, so that the drive device and the slide rail 3 form a rigid connection and ensure the stability of power transmission. In terms of power output, the motor box is equipped with a first mounting plate 408 and a second mounting plate, which are symmetrical in structure. The first mounting plate 408 has a motor mounting hole in the middle, and the first motor 402 is fixed in the motor mounting hole. The output shaft of the first motor 402 is directly fitted with a transmission gear, which is inserted into the mounting hole of the first roller, forming a direct drive structure of motor, transmission gear and roller. The connection between the second motor 403 and the second roller is the same as that between the first motor and the first roller, and the first roller and the second roller rotate in opposite directions, forming a gap between the two rollers that allows the tipping mechanism contact plate 401 to pass through. Regarding elastic tension, both sides of the first mounting plate 408 are provided with first guide blocks 409, and both sides of the second mounting plate are provided with second guide blocks. The first guide blocks 409 and the second guide blocks are embedded in the guide grooves 407 on the inner wall of the mounting side plate 406, and can slide relative to each other along the guide grooves. The first guide block 409 and the corresponding second guide block are provided with hooks 410. The two hooks 410 are connected by a spring. The preload of the spring makes the first mounting plate 408 and the second mounting plate close to each other, thereby ensuring close contact between the first roller, the second roller and the contact plate 401 and avoiding slippage. Compared with the complex tensioning structure of the toothed belt drive in the prior art, this structure simplifies the transmission chain through a direct drive motor and simplifies the tension adjustment through the combination of guide blocks, springs and hooks, which not only facilitates the assembly of the drive device, but also reduces the difficulty of later maintenance. After the first motor 402 and the second motor 403 are started, they drive the first roller and the second roller to rotate in opposite directions. The static friction between the roller and the contact plate 401 is converted into the power to drive the tipping mechanism 5 to move along the slide rail 3. The preload of the spring can compensate for the wear of the roller in real time, ensuring that the friction always meets the driving requirements and avoiding the tipping mechanism from stopping or getting stuck due to roller wear.

[0030] The drive unit 4 adopts a direct drive and elastic contact power transmission mode. The first motor 402 and the second motor 403 directly drive the corresponding rollers to rotate, avoiding energy loss of intermediate transmission components. The spring applies a preload to the first mounting plate 408 and the second mounting plate through the hook 410, so that the rollers and the contact plate 401 always maintain close contact, ensuring stable friction and thus ensuring that the tipping mechanism 5 moves at a constant speed along the annular slide rail 3, providing a stable conveying foundation for precise sorting. The control system commands the first motor 402 and the second motor 403 to start synchronously, driving the two sets of rotating wheels 404 to rotate. The two sets of rotating wheels 404 rotate synchronously in opposite directions, generating static friction in the same direction with both sides of the contact plate 401, forming a resultant force to push the contact plate 401. The contact plate 401 drives the base 1 to move. The gap between the two sets of rotating wheels 404 provides guidance for the contact plate 401, forming a double guide with the slide rail 3. The sliding wheel set 2 changes sliding friction into rolling friction, reducing resistance and ensuring that the base 1 smoothly drives the tipping mechanism 5 to move. The specific sorting operation procedure of this device is as follows: 1) Material feeding and detection: The material to be sorted is placed on the tray 512 of the tipping mechanism 5. The weight sensor 511 detects the weight of the material in real time and transmits the weight signal to the control system (not shown in the figure). The control system determines the sorting station corresponding to the material according to the preset weight threshold. The first motor 402 and the second motor 403 of the drive device 4 are started. The first roller and the second roller rotate in opposite directions. The friction force drives the contact plate 401 to move, thereby causing the trolley assembly to move the tipping mechanism 5 along the annular slide rail 3 to the target sorting station. During the movement, the sliding wheel group 2 slides along the slide rail 3 to ensure that the tipping mechanism moves smoothly. 2) When the tipping mechanism 5 approaches the target sorting station, the control system controls the push mechanism 6 of that station to operate. The electric push rod 605 is energized and extends. The stabilizing rod 608 moves synchronously with the electric push rod under the guidance of the limit block 609, pushing the pulley 607 to the contact position. The tipping mechanism 5 continues to move, and the inclined plate 506 of the clamping plate 504 contacts the push pulley 607. The push pulley slides along the inclined plate and drives the clamping plate 504 to slowly deflect. The clamping slot 505 gradually disengages from the first end of the tipping plate 509. When the push pulley 607 has basically moved to the highest point of the inclined plate 506, the deflection angle of the clamping plate 504 exceeds the preset value, and the tipping plate 509 loses its constraint. Under the action of the gravitational torque of the pallet 512 and the material, it tilts to the second end. When the second stop 510 of the tipping plate 509 contacts the first stop 507 of the connecting frame 502, the tipping plate stops tilting. The material slides down the pallet 512 to the collection area on the other side of the slide rail 3, thus achieving sorting.

[0031] 3) After sorting is completed, the electric push rod 605 is de-energized and retracted, and the clamping plate 504 is reset around the rotating shaft under its own gravity or the action of the reset spring; the tilting plate 509 is manually or mechanically turned back to the initial position, and its first end is re-clamped into the slot 505 of the clamping plate 504. The tipping mechanism 5 continues to move along the annular slide rail 3 and enters the next sorting cycle. The various embodiments of this disclosure have been described above.
