Description

Technical Field

[0001] This application belongs to the fields of industrial automation and logistics warehousing, and specifically proposes a high-altitude RGV transfer and tilting system that can be applied to batch product processing and / or parcel transfer. Background Technology

[0002] Currently, in industrial automation production and e-commerce automated warehousing and logistics scenarios, it is common to use supporting equipment for batch product processing, unloading, and parcel transfer. For example, a transfer and tilting machine is configured to connect the punching unloading and silo sorting processes. This equipment can achieve stable and efficient material transfer, ensuring the continuous and smooth operation of subsequent sorting, storage, and other processes.

[0003] Existing transfer and tilting material unloading machines generally suffer from the following shortcomings: 1. Insufficient compatibility: They are only compatible with a single or a small number of bins of similar size. When dealing with bins of varying sizes, manual forklift assistance is required. 2. Poor unloading stability: The unloading process relies solely on gravity, which can easily lead to material falling or incomplete unloading, requiring manual secondary cleaning. 3. Low adaptability to working conditions: The adjustable range of the tilting angle is limited, making it difficult to match the optimal unloading angle for different materials. Furthermore, due to the large number and height of the bins, precise docking between the equipment and the material inlet is challenging. 4. Low flexibility: The clamping mechanism has poor versatility, supporting only fixed-size bins, resulting in limited overall adaptability.

[0004] In view of the above, this application is hereby submitted. Summary of the Invention

[0021] Example 1, as Figures 1 to 14 As shown, this application proposes a high-altitude RGV transfer and tilting system for batch processing and transfer of products. For example, the system can be set between the punching unloading and silo sorting processes to transfer the punched parts in batches to the designated silo for subsequent sorting and warehousing operations.

[0022] Specifically, the high-altitude RGV transfer and tilting material unloading system includes: The upper conveyor device 1 is horizontally connected to the RGV mechanism 2, and is used to transfer the pallet carrying the material box from the main conveyor line to the tipping and unloading mechanism 3; RGV mechanism 2 is used to carry the tilting and unloading mechanism 3 and transport it horizontally to the designated location of hopper 4; The flipping and unloading mechanism 3, along with the horizontal movement of the RGV mechanism 2, transports the transferred pallet to the designated location of the hopper 4. Then, during the flipping process, the goods or products in the hopper are dumped into the hopper 4. Finally, it returns to the initial state and returns to the location of the upper conveyor device 1 along with the RGV mechanism 2, ready to receive the next pallet transferred by the upper conveyor device 1. The hoppers 4 are arranged in parallel along the operating direction of the RGV mechanism 2, with at least one set for receiving goods dumped from the tipping and unloading mechanism 3.

[0023] Specifically, the upper conveyor 1 is used to connect one end to the punch press unloading station to carry in and out, and the other end is set horizontally to connect to the loading end of the RGV mechanism 2; for example, the upper conveyor 1 can be set along the conveying direction of the RGV mechanism 2, on the side or end of the RGV mechanism 2. The upper conveying device 1 includes an upper rack body assembly 1.3 that is mounted and fixed to the RGV mechanism 2 via a foot assembly 1.6. Inside the frame of the rack body assembly 1.3, there is a conveyor assembly 1.4 for connecting and conveying pallets after they are joined with the material box, and a conveyor drive assembly 1.5 for driving the horizontal conveying operation of the conveyor assembly 1.4. Conveyor assembly 1.4 can preferably be a chain conveyor or a roller conveyor, etc. The conveyor drive assembly 1.5 can preferably include a drive device including a servo geared motor, a drive shaft, a gearbox and a sprocket / chain transmission mechanism, or a synchronous belt / synchronous pulley transmission mechanism; during the power transmission process, the servo geared motor of the conveyor drive assembly 1.5 can output torque to drive the transmission shaft to rotate, and the sprockets / chains at both ends of the transmission shaft mesh to transmit power accurately and reliably to the chain conveying device of the conveyor assembly 1.4 to drive the pallet to move in the horizontal direction; Two sets of upper rack guide components 1.1 are symmetrically arranged on both sides of the rack body component 1.3 for precise positioning and guidance of pallets. At the same time, the upper rack guide components 1.1 can also provide external protection for the conveyor component 1.4 to avoid collision damage. Along the conveying direction of the conveyor frame assembly 1.4, two sets of first pallet detection assemblies 1.2 and second pallet detection assemblies 1.7 are symmetrically arranged at both ends of the upper rack body assembly 1.3; when the pallet is detected to be in place, the conveyor assembly 1.4 starts to run, so as to smoothly transport the pallet to the ground and into the tipping and unloading mechanism 3, thereby completing the entire process of loading and conveying the upper rack conveyor device 1. The RGV mechanism 2 includes an RGV platform assembly 2.1, and a conveyor platform assembly 2.5 is provided on one side of the RGV platform assembly 2.1 for mounting and fixing the upper shelf conveyor device 1 (specifically, fixedly connected to the upper shelf body assembly 1.3). An RGV track assembly 2.2 is laid on the RGV platform assembly 2.1 along a linear direction, and the RGV vehicle body 2.3 reciprocates along the RGV track assembly 2.2 under the control of the RGV drive device; In addition, at the front and rear ends of the RGV platform component 2.1, there are stop components 2.4 for assisting in braking the RGV vehicle body 2.3 and limiting its running end position, respectively. At the rear end of the RGV platform component 2.1, there are laser reflector components 2.7 and first wireless communication components 2.6 for acquiring and controlling the real-time running position of the RGV vehicle body 2.3. The RGV body 2.3 includes an RGV body frame assembly 2.3.1. A wheel system assembly controlled by an RGV drive device is set at the bottom of the RGV body frame assembly 2.3.1. The RGV drive device preferably includes a power transmission assembly including an RGV servo reduction motor 2.3.2. The output shaft of the RGV servo reduction motor 2.3.2 drives the wheels in the wheel system assembly and, through the linkage of the body with other driven wheels, achieves smooth and synchronous operation along the RGV track assembly 2.2. Furthermore, at the front and rear ends of both sides of the RGV body frame assembly 2.3.1, four sets of guide wheel assemblies 2.3.7 and brush assemblies 2.3.6 are symmetrically arranged and slidably connected to the RGV track assembly 2.2, so as to effectively prevent the RGV body 2.3 from derailing when running along the RGV track assembly 2.2, and at the same time have the function of real-time cleaning of foreign objects on the track, ensuring the accuracy and stability of the transfer process.

[0024] A second wireless communication component 2.3.5 with an integrated wireless communication module is installed on the RGV body frame assembly 2.3.1. The second wireless communication component 2.3.5 and the first wireless communication component 2.6 of the RGV mechanism 2 transmit data through a real-time and stable data interaction link to realize remote control and real-time feedback of the operating status of the RGV body 2.3 during on-track travel; the control system realizes the forward, backward, start, stop and acceleration / deceleration control of the RGV body 2.3 carrying the pallet by issuing signal commands, and supports intelligent allocation of transfer tasks; A laser positioning component 2.3.8 is installed at the front end of the RGV body frame assembly 2.3.1 to position the conveyor platform assembly 2.5. This improves the positioning accuracy and speed control of the RGV body 2.3 while it is running on the track. The real-time feedback of position information enables early deceleration and smooth stopping, preventing overshoot positioning and cargo swaying. Specifically, when the RGV body 2.3 travels to the position of the conveyor platform assembly 2.5, the laser positioning component 2.3.8 performs position detection and confirmation to accurately connect with the main conveyor line and complete the subsequent operation of transferring the pallet to the flipping and unloading mechanism on the RGV body 2.3. The RGV vehicle frame assembly 2.3.1 is equipped with an extreme detection assembly 2.3.3 with an inductive switch assembly and a deceleration detection assembly 2.3.4 with a magnetic switch assembly. Correspondingly, the RGV track assembly 2.2 includes two sets of parallel and fixedly connected tracks 2.2.1. A first extreme deceleration assembly 2.2.2 and a second extreme deceleration assembly 2.2.3 are symmetrically arranged between the two sets of tracks 2.2.1 along the extension direction of the tracks 2.2.1 to fully ensure the safe operation and accurate positioning of the RGV vehicle body 2.3 under high-altitude conditions.

[0025] Specifically, the first limit deceleration component 2.2.2 includes a profile component, a first detection and installation component 2.2.2.1 is provided at the front end of the profile component (towards the upper conveyor device 1), a first magnetic component 2.2.2.2 is provided in the middle of the profile component, and a first limit plate-breaking component 2.2.2.3 is provided at the rear end of the profile component; The second limit deceleration component 2.2.3 includes a profile component, a second detection and installation component 2.2.3.1 is provided at the rear end of the profile component (towards the laser reflector component 2.7 and the first wireless communication component 2.6), a second magnetic component 2.2.3.2 is provided in the middle of the profile component, and a second limit plate-breaking component 2.2.3.3 is provided at the front end of the profile component; When the RGV car body 2.3 reaches the position of the first limit deceleration component 2.2.2, it is already quite close to the end of the track and should be braked. Specifically, when the magnetic switch of the deceleration detection component 2.3.4 on the RGV car body 2.3 triggers the first magnetic component 2.2.2.2 on the first limit deceleration component 2.2.2, the RGV car body 2.3 automatically receives the deceleration command and immediately brakes and gradually stops. If the stop is not timely, the limit detection component 2.3.3 on the RGV car body 2.3 will immediately trigger the first limit stop component 2.2.2.3 to generate an emergency signal. The RGV servo geared motor 2.3.2 on the RGV car body 2.3 will perform an emergency braking action, and the car body will be stopped urgently. At the same time, the stop component 2.4 plays a final protective role to prevent the RGV car body 2.3 from rushing off the platform.

[0026] When the RGV car body 2.3 travels past the conveyor platform assembly 2.5 and reaches the position of the second limit deceleration assembly 2.2.2, it indicates that it is relatively close to the end point of the track and should be braked. The specific braking process is the same as that of the first limit deceleration assembly 2.2.2 mentioned above, and will not be described again here.

[0027] The aforementioned tilting and unloading mechanism 3 includes a tilting power assembly 3.2 fixedly installed on the RGV vehicle body 2.3, and a tilting assembly 3.1 driven by the tilting power assembly 3.2 to achieve reciprocating rotation around a horizontal axis. A tilting conveying assembly 3.4 for carrying and conveying goods is provided on the tilting assembly 3.1. The flipping component 3.1 has a cylindrical, hollow overall frame structure, and a set of C-shaped, concave rolling grooves 3.1.5 are respectively provided on the outer edges of both ends of the flipping frame component 3.1.1. In addition, an upper limit assembly 3.1.7 is axially provided between the two ends of the flipping frame assembly 3.1.1 to clamp the hopper during the flipping process and prevent the hopper from shifting or falling. The aforementioned flipping power assembly 3.2 includes a base frame assembly 3.2.2, and a flipping drive guide assembly 3.2.1 and two sets of non-powered guide assemblies 3.2.6 are symmetrically arranged at the front and rear ends of the base frame assembly 3.2.2 to support and drive the flipping assembly 3.1. The flip drive guide assembly 3.2.1 includes a drive motor assembly 3.2.1.1. The output shaft of the drive motor assembly 3.2.1.1 is linked to the transmission assembly 3.2.1.2 through a gear pair. An array of guide wheel assemblies 3.2.1.3 is provided on the transmission assembly 3.2.1.2. The transmission assembly 3.2.1.2 includes a drive shaft and drive sprockets located at both ends of the drive shaft. The drive sprockets are connected to the single-sided sprocket of the non-powered guide assembly 3.2.6 on the same side through a chain. The non-powered guide assembly 3.2.6 includes a mounting base assembly 3.2.6.3, on which non-powered guide wheels 3.2.6.1 are symmetrically distributed with the guide wheel assembly 3.2.1.3, and a sprocket transmission assembly 3.2.6.2 is connected to the transmission sprocket in the transmission assembly 3.2.1.2 via a chain drive. The guide wheel assembly 3.2.1.3 and the non-powered guide wheel 3.2.6.1 are rotatably nested in the rolling groove 3.1.5. Simultaneously, the chain and chain fixing assembly 3.1.6 connecting the flip drive guide assembly 3.2.1 and the non-powered guide assembly 3.2.6 are both sleeved in the rolling groove 3.1.5. Thus, the flip drive guide assembly 3.2.1 and the non-powered guide assembly 3.2.6 are integrally connected through the rolling groove 3.1.5, the chain, and the transmission sprocket, forming a safety frame that provides support from below and limit movement from above. During the flipping process, the guide wheel assembly 3.2.1.3, the non-powered guide wheel 3.2.6.1, and the chain both provide frame support and guidance, ensuring a smooth and reliable flipping process.

[0028] During the flipping process, all the internal cables rotate with the cable chain under the combined clamping action of the flipping cable chain assembly 3.1.4 of the flipping assembly 3.1 and the cable chain fixing assembly 3.2.3 of the flipping power assembly 3.2, so as to protect the cables from being damaged due to excessive flipping angle. The arc-shaped cable chain groove assembly 3.1.4.2 of the flip cable chain assembly 3.1.4 is a semi-circular C-shaped groove made according to the flip angle, with guide side guards on both sides. The cable chain assembly 3.2.3.3 in the cable chain fixing assembly 3.2.3 should select a rotatable cable chain, and the vertical cable chain groove assembly 3.2.3.2 should leave a gap with the cable chain and have guide side guards on both sides. The interaction between the two cable chain grooves plays a role in guiding, protecting, and preventing the cable chain from swaying.

[0029] When the flipping assembly 3.1 begins to flip under the drive of the flipping drive guide assembly 3.2.1 in the flipping power assembly 3.2, the cable chain of the cable chain assembly 3.2.3.3 on the cable chain fixing assembly 3.2.3 is held by both the arc cable chain groove assembly 3.1.4.2 and the vertical cable chain groove assembly 3.2.3.2 of the flipping cable chain assembly 3.1.4. The moving end of the cable chain will begin to rotate and move along the arc C-shaped groove of the arc cable chain groove assembly 3.1.4.2, and the other side will gradually begin to move away from the vertical cable chain groove assembly 3.2.3.2, and the cable chain will be in an arc state. With the cooperation of the two sides, the cable chain will not sway or collapse, thus protecting the cable inside the cable chain. Similarly, during the rotation of the flip component 3.1, the moving end of the cable chain will begin to rotate and move away from the arc cable chain groove along the arc C-shaped groove of the arc cable chain groove component 3.1.4.2, while the other side will begin to rotate back into the cable chain groove along the vertical cable chain groove component 3.2.3.2, with the cable chain in a vertical state.

[0030] Furthermore, a first protective component 3.1.2 and a second protective component 3.1.3 are respectively provided on the side and end of the inside of the flipping frame assembly 3.1.1. Correspondingly, a third protective component 3.2.7 with an overall structure bent inward is provided on the side end of the bottom frame assembly 3.2.2. These components work together to prevent a large amount of material from splashing during the initial unloading process, thereby achieving zero material loss during the unloading process. Specifically, when the tilting frame assembly 3.1 starts to rotate under the action of the tilting power assembly 3.2, as the tilting angle increases, the material inside the hopper begins to spill. When the rotation angle is small, due to the small inertia and weight, the material in the upper part of the small hopper spills slowly and over a short distance. The space near the pallet side of the tilting frame assembly 3.1.1 is sealed by the first protective assembly 3.1.2 and the second protective assembly 3.1.3 to prevent a small amount of larger material from falling into the tilting frame assembly 3.1 and onto the tilting conveyor assembly 3.4, while smaller material will fall onto the third protective assembly 3.2.7 along with the guard plate and enter the hopper. As the tilting angle increases, a large amount of material spills out. Under the action of inertia and weight, the material spills quickly and over a long distance, all landing on the third protective assembly 3.2.7 on the bottom frame assembly 3.2.2. Because the third protective assembly 3.2.7 bends inward, it ensures that the material falling on both sides will slide into the hopper and will not burst out of the hopper.

[0031] On the bottom frame assembly 3.2.2, along the flipping trajectory of the flipping frame assembly 3.1, there are symmetrically paired material pouring position detection assembly 3.2.4, material pouring deceleration detection assembly 3.2.5, and reset position detection assembly 3.2.9 and reset deceleration detection assembly 3.2.11 equipped with slotted photoelectric switches, as well as a first limit detection assembly 3.2.8 and a second limit detection assembly 3.2.12 equipped with limit switches; Specifically, when the flipping frame assembly 3.1 flips to a position close to the set angle, the signal triggered by the material retraction deceleration detection assembly 3.2.5 is fed back to the flipping drive guide assembly 3.2.1 to control the flipping frame assembly 3.1 to start deceleration; when the deceleration reaches the point where the material retraction position detection assembly 3.2.4 is triggered, the flipping drive guide assembly 3.2.1 controls the flipping frame assembly 3.1 to stop rotating. After the material is poured, the flipping drive guide assembly 3.2.1 controls the flipping frame assembly 3.1 to start rotating. When it rotates to near the set angle, the signal from the reset deceleration detection assembly 3.2.11 is fed back to the flipping drive guide assembly 3.2.1 to control the flipping frame assembly 3.1 to start decelerating. When it decelerates to the position of the reset position detection assembly 3.2.9, the flipping drive guide assembly 3.2.1 controls the flipping frame assembly 3.1 to stop rotating. The first limit detection component 3.2.8 and the second limit detection component 3.2.12 are used to send a command to control the motor of the flipping drive guide component 3.2.1 to brake in time and forcibly stop its rotation if the flipping frame component 3.1 does not stop in time during the flipping and rotation process. Furthermore, a stop assembly 3.2.13 is provided on the bottom frame assembly 3.2.2 to forcibly prevent the rotating frame assembly 3.1 from continuing to rotate. The stop assembly 3.2.13 serves as the last line of protection. An origin verification component 3.2.10 is installed on the bottom frame component 3.2.2 for position verification during maintenance and commissioning phases; A hopper arrival detection component 3.3 is installed on the tilting and unloading mechanism 3, and a hopper arrival reflection component 4.7 is installed on the hopper 4. Specifically, when the RGV vehicle 2.3 receives the location of the hopper to be unloaded through the second wireless communication component 2.3.5, the RGV vehicle 2.3 locates the position of the hopper through the laser positioning component 2.3.8, and travels along the track to the vicinity of the hopper. The photoelectric sensor of the hopper arrival detection component 3.3 on the tilting and unloading mechanism 3 interacts with the photoelectric reflection sensor of the hopper arrival reflection component 4.7 on the hopper 4 to accurately locate the RGV's travel position and ensure the smooth tilting and unloading.

[0032] The flipping conveyor assembly 3.4 includes a conveyor assembly 3.4.1 that conveys the pallet in the horizontal direction and a conveyor drive assembly 3.4.5 that controls and drives the operation of the conveyor assembly 3.4.1; The conveyor assembly 3.4.1 may preferably be a chain mechanism, a roller mechanism, or a conveyor belt mechanism; The conveying drive assembly 3.4.5 can preferably be a transmission assembly including a servo geared motor. The output shaft of the servo geared motor is linked to the transmission assembly through a gear pair, driving the sprockets at both ends of the transmission shaft to rotate, thereby driving the conveyor assembly 3.4.1 to move the pallet in the horizontal direction, so as to connect the pallet to the flipping frame assembly 3.1 or to exit it. A pallet detection assembly 3.4.2, an over-limit detection assembly 3.4.3, and a arrival detection assembly 3.4.4 are respectively installed on one side of the conveyor assembly 3.4.1; Specifically, when the pallet is conveyed to its position and close to the flipping component 3.1 under the drive of the flipping conveyor component 3.4, the flipping frame component 3.1.1, the upper limit component 3.1.7 and the flipping conveyor component 3.4 work together to form a multi-directional clamping and lifting of the material box and the pallet together, thereby preventing the material box and the pallet from separating or falling during the flipping process. When the tilting assembly 3.1 starts to rotate, the pallet initially rests against the tilting frame assembly 3.1.1 under the influence of gravity. As the tilting angle increases, the material begins to spill, reducing the load on the pallet. At extreme angles, the hopper on the pallet may detach from the pallet. With the upper limit assembly 3.1.7 installed on top of the tilting frame assembly 3.1.1, the hopper will not detach from the pallet and fall outside the tilting frame due to the multi-directional clamping restraint formed by the upper limit assembly 3.1.7 and the tilting conveyor assembly 3.4. After the material is unloaded, the tilting conveyor assembly 3.4 remains supported under the pallet during the rotation process to prevent the hopper from separating from the pallet. The hopper mechanism 4 includes a hopper frame assembly 4.2 and a hopper interface 4.1 with a chute structure. A hopper door assembly 4.5 controlled by a hopper drive assembly 4.3 and a button assembly 4.6 is provided on one side of the hopper interface 4.1. The hopper door assembly 4.5 is slidably connected to a hopper guide rail assembly 4.4 provided on the hopper frame assembly 4.2. The aforementioned hopper drive assembly 4.3 is preferably a cylinder, the output end of which is fixedly connected to the hopper door assembly 4.5. The hopper door assembly 4.5 moves along the hopper guide rail assembly 4.4 via a slider to open or close the hopper interface 4.1. A photoelectric docking component is installed on one side of the hopper interface 4.1. When the RGV vehicle body 2.4 runs to the designated hopper interface 4.1, it detects the arrival information to ensure that the hopper interface 4.1 is accurately docked after the material is transferred to the hopper interface 4.1. Button assembly 4.6 is used to control the start-up and operation of hopper drive assembly 4.3 to ensure that hopper door assembly 4.5 is temporarily opened when material needs to be transferred and fed.

[0033] Based on the structural design and control principle of the above-mentioned high-altitude RGV transfer and tilting material unloading system, this application can realize the following high-altitude transfer and tilting material unloading process: (1) Material feeding and conveying; In the punch press unloading area, a manual forklift picks up the material box and the mother pallet together and then places it onto the chain conveyor on the steel platform. After the chain conveyor detects the pallet through photoelectric sensors, it automatically transports the pallet to the chain conveyor inside the tilting and unloading mechanism until it is in place.

[0034] (2) RGV positioning; After receiving a specific material receiving instruction from the system via wireless communication, the RGV starts moving. With the help of its own laser rangefinder, it provides real-time feedback on its position and controls acceleration and deceleration to ensure precise stopping at the designated material receiving position.

[0035] (3) Turning the material over and pouring it out; Once the RGV is in position, the tilting drive component of the tilting and unloading mechanism is activated, and the control frame slowly tilts. As the tilting angle increases, the material in the hopper gradually pours out. The protective components a and b in the mechanism work synchronously to catch the material that may be thrown out due to the tilt of the hopper, ensuring that all materials are fed into the designated hopper.

[0036] (4) Reset and return of empty support; Once the limit position detection component confirms that the flipping is in place and the material has been completely emptied, the flipping drive component reverses its rotation to flip the hopper back to its initial position. After the system issues a command to return the empty pallet, the RGV moves to the chain conveyor docking position, and the conveyor of the flipping and unloading mechanism transports the empty pallet to the chain conveyor. Once the pallet is in place, a manual forklift picks it up and places it in the empty pallet storage area.

[0037] (5) Sorting in the silo; According to the actual material demand, the sorting personnel press the demand button, the cylinder starts and opens the silo door, and the material is poured from the silo onto the sorting workbench; after sorting is completed, the closing button is pressed, the silo door closes, and it waits for the next material call instruction.

[0038] After unloading is completed, the tilting drive motor reverses and resets to its initial position. The system issues an empty pallet return command, and the RGV travels to the chain mechanism docking position. The conveyor within the tilting and unloading mechanism transports the pallet to the chain conveyor. Once the pallet is in place, it is manually transferred to the empty pallet storage area by a forklift.

Those skilled in the art can draw inspiration from this and directly derive other alternative structures that conform to the design concept of this invention. Other structural features derived therefrom should also fall within the scope of the solutions described in this invention.
