Description

Technical Field

[0001] This utility model relates to the field of bearing manufacturing and automation technology, and in particular to a tapered roller stacking device for sorted bearings. Background Technology

[0002] As a key rolling element in bearings, the efficient and precise processing of tapered rollers after sorting is crucial for ensuring bearing product quality and improving production automation. In automated production processes for tapered roller bearings, ensuring that sorted rollers quickly and neatly enter subsequent collection or assembly stages has always been a focus of industry attention. Improper handling in this stage can not only affect the overall production cycle but also introduce uncertainties due to manual intervention, increasing production costs and even impacting the final product consistency and reliability.

[0003] Currently, while some automated solutions have emerged in the post-sorting processing technology of bearing rollers, aiming to replace traditional manual operations, they still fall short in achieving full automation and efficient continuous operation. For example, patent application CN116786468A discloses a bearing roller sorting machine and its working method. This device mainly uses specific transition and guiding mechanisms, combined with a movable material box positioning mechanism, to allow the sorted rollers to automatically fall into the preset holes in the material box, achieving preliminary automated arrangement of the rollers within a single material box. Compared to traditional manual arrangement, this solution improves the automation level and arrangement regularity of roller boxing to a certain extent.

[0004] However, the aforementioned existing technologies still have the following technical shortcomings in pursuing higher efficiency and more complete automated processes:

[0005] ① Existing technologies typically require manual intervention to replace empty bins and remove full bins after a single bin is full. This manual intervention not only interrupts the continuous operation of the equipment and reduces overall production efficiency, but also fails to completely eliminate reliance on human labor, especially in high-volume, fast-paced production models.

[0006] ② Lack of integrated automated transfer and palletizing functions, resulting in limited overall automation: Existing automated processes mainly focus on the filling process of conical rollers entering a single material box. For crucial subsequent steps such as the automatic and smooth transfer of full material boxes to designated workstations, and the automatic grabbing and palletizing of multiple full material boxes according to preset rules to form units that meet warehousing or logistics requirements, existing technologies fail to provide a seamless, integrated automated solution. Utility Model Content

[0007] The purpose of this utility model is to provide an automatic stacking device for tapered roller bearings after sorting, which realizes the full-process automation from automatic boxing of tapered rollers, automatic continuous supply of empty boxes, automatic gripping and transfer of full boxes to final automatic stacking, so as to significantly improve production efficiency and automation level.

[0008] This application provides a stacking device for sorted tapered roller bearings, comprising: a roller conveyor line for conveying the sorted tapered rollers in a lying position; a roller transition module connected to the unloading port of the roller conveyor line, the roller transition module adjusting the tapered rollers to a vertical boxing posture and transferring them to a hopper in the area below their outlet; the hopper being positioned by a roller arrangement module, which loads the tapered rollers one by one into designated compartments of the hopper; the hoppers on the roller arrangement module being supplied by a hopper supply device; the hopper supply device having at least two independent empty hopper supply stations; and the device being used when the hoppers on the roller arrangement module are full. The roller arrangement module adjusts its position and moves to a preset handover station. A robotic palletizing device then picks up full boxes and automatically stacks them on a pallet according to preset rules. The roller conveyor line, roller transition module, roller arrangement module, box supply device, and robotic palletizing device are all electrically connected to a central controller. The central controller coordinates the sequence and logic of each module's actions, achieving fully automated operation of the tapered rollers after sorting, from automatic reception, posture adjustment, precise loading into boxes, continuous automatic supply of empty boxes, automatic picking and transfer of full boxes to pallets, and stacking according to preset rules. This significantly reduces manual intervention, ensures production continuity and efficiency, and comprehensively improves the automation level and production cycle of the post-sorting processing of bearing tapered rollers.

[0009] Furthermore, to precisely control the orderly and timely supply of tapered rollers to the subsequent roller transition module on the conveyor line, this application proposes that the roller conveyor line includes guide troughs for limiting the travel trajectory of the tapered rollers and roller stopping mechanisms for blocking or releasing the tapered rollers at preset times. The roller stopping mechanism is driven by a miniature cylinder and electrically connected to the central controller, achieving effective constraint on the travel trajectory of the tapered rollers and precise blocking or release at preset times. This ensures that the rollers can be stably conveyed to the roller transition module according to the predetermined path and cycle time, avoiding roller accumulation or untimely supply, and laying a reliable foundation for subsequent automated processing.

[0010] Furthermore, to reliably and accurately transform the tapered roller into a vertical boxing posture and precisely guide it into the designated compartment of the cassette, this application proposes a roller transition module comprising a turning section, a centering section, and a positioning section. The turning section guides the tapered roller from a lying posture to a vertical boxing posture under gravity through an internal transition channel. The centering section is located below the exit of the turning section and guides the tapered roller towards the center of the exit under gravity through an internal ramp channel. The positioning section is located below the exit of the centering section and guides the tapered roller to narrow its center range through its internal tapered channel, ensuring its smooth descent into the designated compartment of the cassette. By utilizing gravity to guide the tapered roller from a lying posture to a vertical boxing posture smoothly and automatically, and gradually performing secondary and tertiary centering, the roller is ultimately ensured to fall smoothly and accurately into the designated compartment of the cassette.

[0011] Furthermore, to detect in real time whether the tapered rollers have accurately reached the exit position of the roller transition module, so that the central controller can make precise control based on the actual state, this application also proposes that the positioning section be equipped with a proximity sensor. The sensor detects whether the tapered rollers are in place and transmits the signal to the central controller for determining the next action. This avoids production abnormalities caused by missed loading or roller jamming, further improving the stability and accuracy of the automated boxing process.

[0012] Furthermore, to achieve precise and automatic alignment of each designated partition of the material box directly beneath the tapered rollers falling from the roller transition module, thus ensuring the orderly arrangement of the rollers, this application proposes a roller arrangement module comprising an X-axis sliding module, a Y-axis sliding module, and a material box positioning device. The material box positioning device is mounted on the Y-axis sliding module platform to support the material box, and the Y-axis sliding module is mounted on the X-axis sliding module platform. The central controller precisely positions the X-axis and Y-axis sliding modules in the horizontal plane, enabling each designated partition of the material box to move sequentially directly beneath the tapered rollers falling from the roller transition module. This achieves the sequential, orderly, and precise filling of the tapered rollers into different partitions, ensuring the neat arrangement of the rollers within the material box and meeting the requirements of subsequent processes.

[0013] Furthermore, to achieve an automated and monitorable empty box supply solution, this application proposes that each empty box supply station includes an empty box storage area, a push cylinder, and a box detection sensor. The empty box storage area is suitable for multiple empty boxes stacked under gravity. The push cylinder is located at the bottom of the empty box storage area and pushes a single empty box to the box-picking position of the roller arrangement module. The box detection sensor is used to monitor the empty box balance of the empty box supply station in real time and feeds the monitoring signal back to the central controller to trigger switching actions and / or alarms. This ensures a continuous and automatic supply of empty boxes, significantly reduces production downtime caused by empty box supply problems, and greatly improves the continuous operation capability and automation level of the equipment.

[0014] Furthermore, to achieve stable and reliable gripping of boxes filled with rollers, and to efficiently and flexibly transfer and stack full boxes from the filling station to the pallet within a specified large area, this application proposes that the boxes be equipped with handles at both ends; the gripper of the robotic palletizing device grips the full boxes by gripping the handles; the robotic palletizing device has a truss structure, and its gripping range covers the entire area including the preset handover station of the roller arrangement module and the pallet. This enables efficient and automatic precise transfer of full boxes from the filling position to the pallet and neat stacking according to preset rules.

[0015] Furthermore, to accommodate pallets of different sizes and assist in their precise positioning at the palletizing station, thereby ensuring palletizing quality and stability and enhancing the versatility of the device, this application proposes that the pallet's positioning area has guide plates at both ends along its length and a positioning plate at at least one end along its width. Both the guide plates and the positioning plates have adjustable holes. These adjustable holes allow them to provide auxiliary positioning when empty pallets of different sizes are placed by a forklift. This ensures the accuracy of the pallet's position, which is crucial for the subsequent precise and stable stacking of full boxes by the robotic palletizing device, thus enhancing the device's adaptability to pallets of different specifications and the accuracy and stability of the palletizing operation.

[0016] Furthermore, to enhance the usability and maintainability of complex automated systems integrating multiple functional modules, this application proposes a central controller comprising a programmable logic controller (PLC) or an industrial computer (IPC), and a human-machine interface (HMI). The HMI is used by operators for parameter setting, start / stop control, status monitoring, and fault information viewing. This improves the device's intelligence, operability, maintainability, and management efficiency, facilitating rapid response to production changes and timely handling of abnormal situations, thereby ensuring the long-term stable and efficient operation of the entire automated palletizing system.

[0017] The technical advantages of this application are as follows:

[0018] 1. This application, by setting up a material box supply device with at least two independent empty material box supply stations, enables continuous and automatic supply of empty material boxes. When the empty material boxes in one supply station are exhausted, the system can automatically switch to the other supply station, thereby avoiding production interruptions caused by manual replacement of empty material boxes, ensuring continuous and efficient operation of the device, and significantly improving equipment utilization and overall production efficiency.

[0019] 2. This application, by setting up a robotic palletizing device and having it work in conjunction with a roller arrangement module, achieves automated gripping, transfer, and palletizing of full boxes from the filling station to the pallet according to preset rules. Combined with the roller conveyor line, roller transition module, and roller arrangement module for the automated handling of tapered rollers, a fully automated operation is achieved from automatic roller boxing to automatic palletizing of full boxes. This significantly reduces manual intervention, lowers labor intensity, reduces human error, and effectively reduces production costs.

[0020] 3. This application uses a central controller to coordinate and control all core modules, including the roller conveyor line, roller transition module, roller arrangement module, material box supply device, and robotic palletizing device. This enables seamless connection and collaborative operation of the action sequence and logic of each module, integrating previously separate automation units into a highly efficient overall system, comprehensively improving the automation level of bearing tapered roller sorting post-processing and the overall operating efficiency of the production line.

[0036] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0037] This application provides an embodiment of a sorted bearing tapered roller stacking device, such as... Figures 1-5 As shown, Figures 1-3 As shown, the sorted bearing tapered roller palletizing device in this embodiment mainly includes: a roller conveyor line 1, a roller transition module 2, a roller arrangement module 4, a material box supply device 5, a robot palletizing device 6, a pallet 7, and a central controller 8; wherein:

[0038] Roller conveyor line 1 is located at the starting end of the device and is used to receive and transport the sorted tapered rollers that are traveling in a lying-down manner. Its discharge port is connected to the inlet of roller transition module 2.

[0039] The roller transition module 2 is located at the end of the roller conveyor line 1. It is used to adjust the lying conical rollers to a vertically downward boxing posture and to transfer the rollers to the material box 3 (carried by the roller arrangement module 4) located directly below it through its outlet.

[0040] The roller arrangement module 4 is located below the roller transition module 2. It is used to support the material box 3 and moves the material box 3 precisely in the horizontal plane according to the instructions of the central controller 8, so that the rollers can be loaded into the designated partition 31 of the material box 3 one by one in an orderly manner.

[0041] The material box supply device 5 is located on one side of the roller arrangement module 4 or at a convenient feeding position, and is used to store and automatically supply empty material boxes 3 to the roller arrangement module 4. The device includes at least two independent empty material box feeding stations 51.

[0042] The robot palletizing device 6 is usually set within the area that can cover the full box handover station of the roller arrangement module 4 and the palletizing area of ​​the pallet 7. It is used to automatically grab the full box after the box 3 is filled and place it on the pallet 7.

[0043] The pallet 7 is placed in the working area of ​​the robot palletizing device 6 to carry the neatly stacked full boxes.

[0044] The central controller 8 (e.g., PLC or industrial PC) is the control core of the entire device. It controls the coordinated actions of the aforementioned execution modules (e.g., motors, cylinders, robots, etc.) through electrical connections (e.g., wired or wireless communication) and receives signals from the sensors.

[0045] Through the coordinated operation of automated modules, a continuous automated process is achieved, from roller conveying to box filling and then to full box palletizing. The multi-station box supply device avoids downtime caused by manual box replacement, improving production efficiency. The robotic palletizing device ensures precise positioning of full boxes on the pallet, improving palletizing quality and space utilization. The unified scheduling by the central controller ensures the coordinated operation of the entire system, reducing potential conflicts and errors.

[0046] Reference Figures 3-5 In a preferred embodiment, the roller conveyor line 1 can be a belt conveyor or similar form. To ensure stable roller transport, a guide groove plate 11 is provided on its upper surface. The groove width of the guide groove plate 11 is adapted to the diameter of the tapered roller, effectively limiting the lateral movement of the roller. At the end of the conveyor line 1, near the inlet of the roller transition module 2, a roller stopping mechanism 12 is provided. This roller stopping mechanism 12 can be a telescopic stop rod driven by a miniature cylinder. The action of the miniature cylinder is controlled by a central controller 8.

[0047] The guide plate 11 ensures that the rollers move along a predetermined trajectory. The roller stopping mechanism 12 extends a stop bar to temporarily block the rollers from moving forward, or retracts the stop bar to release the rollers, according to the instructions of the central controller 8, thereby achieving precise control of the roller supply cycle and preventing the rollers from accumulating or being insufficiently supplied at the entrance of the transition module 2.

[0048] Specifically, in this preferred embodiment, the transition module 2 is a specially designed channel structure used to adjust the attitude using the weight of the roller itself. It sequentially includes a steering section 21, a centering section 22, and a positioning section 23.

[0049] Turning section 21: It has a transition channel 211 inside that gradually transitions from a lying posture to an upright posture.

[0050] Centering section 22: Located below the turning section 21, it has a ramp channel 221 with a tendency to converge toward the center, which is used for the initial lateral centering of the roller whose attitude has been initially adjusted.

[0051] Positioning section 23: Located below the centering section 22, this conical channel 231 has an outlet shape similar to the cross-section (usually circular) of the roller in its vertical state. It is used for final precise center positioning of the roller, ensuring that it falls accurately into the material box partition. A proximity sensor 232 (such as a fiber optic sensor or a small photoelectric sensor) is installed on the inner wall of the outlet of the positioning section 23 or immediately adjacent to the outlet to detect whether the roller passes smoothly.

[0052] When the tapered roller enters the roller transition module 2 from the roller conveyor line 1, under the influence of gravity and guided by the specially designed channels in each section, its posture automatically changes from lying down to an upright position with the larger end facing down. It is then precisely guided to the center of the module outlet, ready to fall into the material box. After the proximity sensor 232 detects the roller's passage, it sends a signal to the central controller 8.

[0053] Reference Figures 2-3 In a preferred embodiment, the material box 3 is an open container with a certain depth, and its interior is divided into multiple partitions 31 of the same size by partitions. Each partition 31 is used to accommodate a vertically oriented conical roller. Handles 32 are provided on both sides or at specific locations of the material box 3 to facilitate robot gripping.

[0054] The roller arrangement module 4 is located below the roller transition module 2 and is used to support the material box 3, and to precisely move the material box 3 in the horizontal plane according to the instructions of the central controller 8. This module includes:

[0055] X-axis sliding module 41: A ball screw slide driven by a servo motor is used to achieve precise movement of the material box in the X direction (left and right direction).

[0056] Y-axis sliding module 42: Also using a ball screw slide driven by a servo motor, it is set on the platform of X-axis sliding module 41 to realize the precise movement of the material box in the Y direction (front and back direction).

[0057] Material box positioning device 43: set on the platform of Y-axis sliding module 42, used to stably support and position material box 3.

[0058] The central controller 8 precisely controls the movement of the X-axis and Y-axis sliding modules according to the preset packing order (e.g., row by row and column by column) and the roller drop signal obtained from the proximity sensor 232, so that each designated partition 31 of the hopper 3 can move sequentially and accurately directly under the tapered roller falling from the roller transition module 2. This process continues until the hopper is completely filled.

[0059] Through the aforementioned technical solution, thanks to the adoption of a high-precision XY sliding module and intelligent control system, the material box can move quickly and accurately to the predetermined position, greatly improving the efficiency and accuracy of roller boxing. Simultaneously, this automated arrangement method eliminates the uncertainties of manual operation, ensuring that each roller accurately falls into the designated partition, thereby improving product quality consistency. Furthermore, the system's flexibility allows it to adapt to material boxes of different sizes and layouts, enhancing the adaptability and versatility of the production line.

[0060] Reference Figures 1-3 In a preferred embodiment, the tin box supply device 5 is used to solve the problem of continuous supply of empty tin boxes. The device has at least two independent empty tin box supply stations 51. Each empty tin box supply station 51 includes an empty tin box storage area 511, a push cylinder 512, and a tin box detection sensor 513.

[0061] Specifically, the empty box storage area 511 adopts a vertical or vertically stacked structure, where multiple empty boxes 3 are naturally stacked under gravity, and internal guide rails can be set to ensure the alignment of the empty boxes. A push cylinder 512 is located at the bottom of the empty box storage area 511, and its push rod stroke matches the thickness of a single empty box 3. When the roller arrangement module 4 needs an empty box, the push cylinder 512, under the command of the central controller 8, pushes the bottom single empty box 3 along the horizontal guide rail to the box-retrieving position of the roller arrangement module 4.

[0062] The material box detection sensor 513 is a photoelectric sensor installed on the side wall of the empty box storage area 511. It monitors the remaining amount of empty material boxes 3 in real time by detecting the stacking height. For example, when the remaining amount is lower than a preset threshold (e.g., 2 boxes remaining), the sensor 513 feeds back a low remaining amount signal to the central controller 8. The central controller 8 then controls another empty material box feeding station 51 to start pushing, or triggers an alarm through the human-machine interface (HMI) to prompt manual replenishment, thereby ensuring the continuous operation of the automated production line.

[0063] Through the above technical solution, empty material boxes can be continuously and stably supplied to the roller arrangement module, reducing the frequency of manual intervention and improving production efficiency. Meanwhile, the real-time monitoring function ensures timely replenishment of empty material boxes, avoiding production interruptions due to material box shortages. Furthermore, the setup of multiple independent feeding stations increases system redundancy and flexibility, further improving the overall equipment reliability and continuous operation capability.

[0064] Reference Figure 2 In a preferred embodiment, to address the issues of insufficient stability in gripping full boxes and limited operating range, the robot palletizing device 6 has been optimized in this embodiment.

[0065] The robotic palletizing device 6 adopts a truss structure, and its gripping range can completely cover the preset handover station of the roller arrangement module 4 and the entire range of the pallet 7.

[0066] Its end effector is a gripper 61, which grips a full material box by gripping the handles 32 at both ends of the material box 3. The handles 32 can have an L-shaped structure, and the gripper 61 is equipped with matching pneumatic grippers. The inner side of the grippers can be provided with anti-slip texture to increase friction. The end of the gripper 61 can also be equipped with a vision positioning system to achieve precise positioning and gripping by recognizing the position of the handles 32.

[0067] Once the full container is moved to the handover station, the robotic palletizing device 6 moves above it, and the gripper 61 descends to firmly grasp the handle 32. Due to the symmetrical gripping points, the container 3 remains stable during lifting and movement, preventing tilting. Subsequently, the truss structure moves the full container to a predetermined position above the pallet 7 and places it precisely.

[0068] Through the above technical solution, this application achieves automatic gripping and palletizing of full boxes. The robotic palletizing device can accurately grip full boxes and automatically place them on pallets according to preset rules, without manual intervention. The large coverage of the truss structure ensures the continuity and flexibility of the palletizing process. This design improves production efficiency, reduces labor costs, and ensures the accuracy and stability of palletizing.

[0069] Reference Figure 1 In a preferred embodiment, to address the palletizing accuracy issue caused by differences in pallet size, the positioning area of ​​the pallet 7 in this embodiment has an adjustable positioning structure. Guide plates 71 are provided at both ends in its length direction, and a positioning plate 72 is provided at least one end in its width direction. Both the guide plates 71 and the positioning plate 72 have adjustable holes 73.

[0070] Specifically, the guide plate 71 is equipped with guide wheel sets 711, which slide and guide the pallet 7 frame via the guide wheel sets 711 on both the left and right sides. The guide plate 71 and the positioning plate 72 are connected to the fixed frame of the positioning area by adjustable holes 73. When using empty pallets of different sizes, the operator moves the guide plate 71 and the positioning plate 72 and locks their positions by tightening bolts, thereby forming a positioning reference that matches the actual size of the pallet, ensuring accurate positioning when the forklift places the pallet and guaranteeing subsequent stacking accuracy.

[0071] Reference Figure 6 In a preferred embodiment, to address the issues of opaque information and inconvenient parameter adjustment during multi-module collaborative operation, the central controller 8 of this embodiment uses a programmable logic controller (PLC) or an industrial computer (IPC) as its core and is equipped with a human-machine interface (HMI).

[0072] The central controller 8 communicates with each module via industrial Ethernet to coordinate their action timing. The human-machine interface (HMI) (e.g., a 10.1-inch touchscreen) is divided into parameter configuration, operating status, and alarm information areas. Operators can use the HMI to set parameters (such as hopper spacing and stacking layers), control start / stop, monitor real-time status (such as graphical displays of hopper filling progress and equipment location), and view fault information. When an anomaly is detected (such as insufficient hopper volume or abnormal sensor signals), the HMI will immediately provide a warning through color-coded alerts (such as a red warning bar) and audible alarms, and display fault codes and troubleshooting suggestions, significantly improving the system's controllability and maintainability.
