Description

Technical Field

[0001] This utility model relates to the field of sorting equipment technology, and in particular to a sorting tipping bucket 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] However, most existing sorting tipping bucket devices use an impact-type unlocking method to achieve tipping. This involves pushing a component to directly impact the locking structure, such as the pallet, to release the lock between the pallet and the tipping bucket, thus enabling the tipping bucket to flip. This impact-type unlocking method generates a large impact force during the impact process, which can easily damage the pallet, tipping bucket, and pushing component, shortening the service life of the equipment. Moreover, the impact generates a lot of noise, which has an adverse effect on the working environment. In addition, the excessive impact force may also damage the items inside the tipping bucket or cause them to tilt, affecting the sorting accuracy and effect. Therefore, there is a particular need for a sorting tipping bucket device. Utility Model Content

[0004] The main purpose of this utility model is to provide a sorting tipping device to solve the problems mentioned in the background art.

[0005] A sorting tipping device, comprising: The tipping mechanism includes a trolley assembly, a mounting frame, a tipping plate, and a clamping plate, wherein: The flip plate is horizontally mounted on top of the mounting frame in a rotatable manner, and a tray is provided above the flip plate; The card plate is vertically mounted on the side of the mounting frame in a rotatable manner. The upper end of the card plate is provided with a card slot, and the lower end of the card plate is provided with an inclined plate. The inclined plate is inclined and protrudes in a direction away from the mounting frame. The trolley assembly consists of a base and a set of sliding wheels from top to bottom. The trolley assembly can move on the slide rail under the drive of the drive structure, and the mounting bracket is fixed on the base. It also includes a push mechanism, which is mounted on a slide rail, and the electric push rod of the push mechanism can extend; The first end of the flip plate can be locked in the slot of the pallet; after the electric push rod of the pushing mechanism extends, it can cooperate with the inclined plate of the pallet and deflect the pallet; when the pallet deflects, the first end of the flip plate is released from the slot of the pallet, and the pallet flips to the side towards the second end of the flip plate under the action of gravity.

[0006] The sorting tipping device achieves tipping triggering through the cooperation of a pallet ramp and an electric push rod in the pushing mechanism. Compared to existing technologies that use instantaneous impact or hook-like instantaneous release, this method offers a significant low-impact advantage. The ramp at the lower end of the pallet protrudes away from the mounting frame. After the electric push rod extends, it forms continuous contact with the ramp. During the movement of the tipping mechanism, the electric push rod slowly slides along the ramp, driving the pallet to slowly deflect around the side of the mounting frame until the pallet slot disengages from the first end of the tipping plate. This slow deflection and release triggering mode avoids structural damage to the tipping mechanism caused by instantaneous impact, reduces component wear, significantly extends the overall service life of the device, and lowers later maintenance and replacement costs.

[0007] Preferably, the mounting frame further includes a vertically arranged support frame and a connecting frame horizontally fixed in the middle of the support frame; the card plate is rotatably mounted on the first end of the connecting frame, and the flip plate is rotatably mounted on the top of the support frame.

[0008] The vertical support frame serves as the main load-bearing component of the mounting frame. The flip plate is directly installed at its top. The gravity load of the flip plate and the material can be vertically transferred to the base along the support frame through the vertical rigid structure. The horizontal connecting frame is fixed in the middle of the support frame, and the clamping plate is installed at the first end of the connecting frame. The rigid support of the connecting frame can ensure that the clamping plate always rotates stably around the fixed axis when it is deflected by the force of the pushing mechanism. The clamping plate will not deviate from its deflection trajectory due to the deformation of the connecting frame, thus ensuring the reliability of triggering.

[0009] Preferably, the second end of the connecting frame is provided with a first stop, and the flip plate is also provided with a second stop. When the pallet is tilted, the first stop and the second stop cooperate to limit the tilt angle of the pallet.

[0010] When the tilting plate is tilted to the side, if there is no limit mechanism, the continuous action of gravity will cause the end of the tilting plate to quickly hit the mounting bracket or slide rail, resulting in a violent impact that deforms the structure of the tilting plate and the tray. On the other hand, it will also be transmitted to the weight sensor, causing damage to the internal components of the sensor. The cooperation of the first and second stops can buffer the impact. When the stops make contact, they can quickly absorb the rotational kinetic energy of the tilting plate, preventing the tilting plate from directly hitting other components. At the same time, the limiting action occurs when the tilting plate is tilted to the preset angle. At this time, the rotational speed of the tilting plate has not yet reached its maximum value, effectively protecting the tilting plate, the tray, the weight sensor and other core components, extending their service life and reducing replacement costs.

[0011] Preferably, the pallet is integrally formed, including a flat plane at the upper end and an inclined plate at the lower end that protrudes from the flat plane and is inclined outward. During the movement of the trolley assembly toward the pushing mechanism, the electric push rod extends and the front end of the electric push rod pushes the pallet along the inclined plate, causing the pallet to deflect.

[0012] The inclined plate protrudes away from the connecting frame, and its movement space is independent of the sliding wheel assembly, base and other components of the trolley assembly. When the electric push rod pushes the plate to deflect, the inclined plate will not collide with the slide rail, contact plate and other structures. At the same time, the contact between the flat upper surface and the tipping plate is surface contact, which eliminates the need for additional positioning protrusions, simplifies the overall structure of the plate and ensures the compactness of the tipping mechanism.

[0013] Preferably, the pushing mechanism includes a fixed plate, one side of which is equipped with a pushing pulley and the other side is connected to an electric push rod. The pushing mechanism also includes a stabilizing rod, which is arranged side by side with the electric push rod and fixed on the fixed plate. The stabilizing rod is guided and limited by a limiting block.

[0014] The extended end of the electric push rod is rigidly connected to one side surface of the fixed plate, and the other side surface of the fixed plate is fixed with bolts to drive the pulley. At the same time, a stabilizer rod is also fixed in parallel on the fixed plate. The stabilizer rod is set parallel to the electric push rod, and the end of the stabilizer rod away from the fixed plate passes through the guide hole of the limit block. The limit block 609 is fixed to the inner wall of the outer shell 602, forming a complete power transmission chain of electric push rod driving, stabilizer rod guiding, fixed plate transmitting force, and drive pulley contact.

[0015] Preferably, the trolley assembly has a contact plate below the sliding wheel assembly, and a drive mechanism is located below the slide rail. The rollers of the drive mechanism drive the contact plate to move through friction. The slide rail is a circular track, and multiple tipping mechanisms are arranged sequentially along the circular track. At least one pushing mechanism is included on one side of the slide rail, and the tipping mechanism tilts to the other side of the slide rail under the action of the pushing mechanism.

[0016] The circular slide rail forms a closed-loop path consisting of a feeding station, a weight detection section, a sorting station, and a reset section. Multiple tipping mechanisms move sequentially along the track. Compared to the design of a linear slide rail that requires back-and-forth conveying, this avoids wasted idle time. The pushing mechanism is fixed to one side of the slide rail, and the tipping mechanism tilts to the other side of the slide rail under the action of the pushing mechanism. During sorting, the material slides away from the pushing mechanism and can fall directly into a pre-set collection container on the other side of the slide rail, such as a material box or conveyor belt. At the same time, the circular track does not require additional return space, and pushing mechanisms can be added along different sides of the circular slide rail. Multiple tipping mechanisms 5 pass through the corresponding stations in sequence according to a preset program, realizing a single track for multiple sorting functions. It can meet the classification needs of multiple specifications of materials without changing the equipment, thus improving the versatility of the equipment.

[0017] Other beneficial effects of this invention are further illustrated in the specific embodiments. Attached Figure Description

[0026] The following embodiments will provide a detailed description of a sorting tipping device of this application.

[0027] 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 mechanism 4 is fixed on the bottom side of the slide rail 3 to move the aforementioned multiple tipping mechanisms, forming a collaborative system of driving, conveying, detection, and sorting. The driving mechanism 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 4 The 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 mechanism 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.

[0028] like Figures 1-5As 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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 mechanism 4 is fixed to the bottom side of the annular slide rail 3 by bolts, so that the drive mechanism 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 mechanism, 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.

[0035] The drive mechanism 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 in intermediate transmission components. The spring applies a preload to the first mounting plate 408 and the second mounting plate through the hook 410, ensuring 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 transforms 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 mechanism 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.

[0036] 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.
