Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, and in particular to a buffer device for bearing production. Background Technology

[0002] In the large-scale production of bearings, the processing flow often involves multiple steps, with bearings transferred between these steps via conveyor belts and other transport equipment. However, due to differences in processing efficiency between different steps, asynchronous bearing transfer can easily occur between preceding and subsequent steps: when the preceding step has high processing efficiency, the subsequent conveyor belt may be unable to receive the bearings in time, leading to bearing accumulation and affecting the normal continuous production of the preceding step; conversely, when the preceding step experiences a temporary halt due to equipment debugging, raw material replenishment, or other reasons, the subsequent step may run idle due to a lack of bearing supply, reducing the overall operating efficiency of the production line. Utility Model Content

[0003] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes a buffer device that can realize the orderly temporary storage of bearings and flexibly coordinate the rhythm of the preceding and following processes.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A bearing production buffer device includes a first conveyor belt, a buffer device, and a second conveyor belt arranged sequentially. The buffer device includes a rotating disk with several horizontal bars evenly distributed around its circumference. A buffer vertical bar is provided at the outer end of each horizontal bar. Bearings can be stacked sequentially on the buffer vertical bar. The device also includes a first conveying device and a second conveying device. The first conveying device is used to convey the bearings on the first conveyor belt one by one to the buffer vertical bar, and the second conveying device is used to convey the bearings on the buffer vertical bar one by one to the second conveying device.

[0006] In some embodiments, the first conveying device and the second conveying device have the same structure, including a pneumatic gripper, a lateral movement mechanism for driving the pneumatic gripper to move laterally, and a lifting mechanism for driving the bearings stacked on the buffer rod to lift upward.

[0007] In some embodiments, the lifting mechanism includes a lead screw module, a lifting plate is provided on the movable seat of the lead screw module, and a support plate is movably sleeved on the buffer vertical rod. The lifting plate moves upward to lift the support plate.

[0008] In some embodiments, the lifting plate is provided with a clearance notch for avoiding the buffer vertical rod, and the lifting plate can move below the buffer vertical rod along with the moving seat of the lead screw module.

[0009] In some embodiments, a baffle for preventing bearing movement is provided at the end of the first conveyor belt.

[0010] In some embodiments, guide strips are provided at intervals on both the first conveyor belt and the second conveyor belt.

[0011] In some embodiments, the conveying end face of the first conveyor belt is higher than the end face of the buffer vertical bar.

[0012] In some embodiments, the end face of the buffer rod is higher than the conveying end face of the second conveyor belt.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Bearings are temporarily stored by the buffer rods on the rotating disc. When the first conveyor belt (the side of the preceding process) is carrying a large number of bearings, the first conveying device can transfer the bearings one by one to the buffer rods for orderly stacking and temporary storage, avoiding the accumulation of bearings on the first conveyor belt. When the second conveyor belt (the side of the following process) needs bearings, the second conveying device can pick up the bearings one by one from the buffer rods and transfer them to the second conveyor belt, ensuring that the following process will not be interrupted by a brief pause in the preceding process. This effectively coordinates the production rhythm of the preceding and following processes and ensures the continuous and stable operation of the entire production line.

[0015] 2. By flexibly storing and releasing bearings, the previous process was prevented from stopping due to accumulation or the subsequent process from running idle due to material shortage. This reduced the ineffective waiting time of the production line, thereby improving the operating efficiency and equipment utilization of the entire bearing production line.

[0019] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0020] like Figures 1-3The illustrated bearing production buffer device includes a first conveyor belt 1, a buffer device 2, and a second conveyor belt 3 arranged sequentially. The buffer device includes a rotating disk 4, with a plurality of horizontal bars 5 evenly distributed along the circumference of the edge of the rotating disk 4. A buffer vertical bar 6 is provided at the outer end of the horizontal bars 5. Bearings 10 can be stacked sequentially on the buffer vertical bar 6. The device also includes a first conveying device 7 and a second conveying device 8. The first conveying device 7 is used to convey the bearings 10 on the first conveyor belt 1 one by one to the buffer vertical bar 6, and the second conveying device 8 is used to convey the bearings 10 on the buffer vertical bar 6 one by one to the second conveying device 8.

[0021] After the bearing 10 is conveyed from the previous process to the first conveyor belt 1, the first conveying device 7 is activated, grabbing the bearings 10 one by one on the first conveyor belt 1 and accurately transferring them to the buffer vertical bar 6, so that the bearings 10 are stacked in an orderly manner on the buffer vertical bar 6 for temporary storage; the rotating disk 4 can rotate according to actual needs, rotating the buffer vertical bar 6 carrying the bearings 10 to the corresponding position of the second conveying device 8; then, the second conveying device 8 is activated, conveying the bearings 10 on the buffer vertical bar 6 one by one to the second conveyor belt 3, and then the second conveyor belt 3 conveys the bearings 10 to the next process.

[0022] By flexibly storing and releasing bearings, the system avoids situations where the preceding process stops due to accumulation or the subsequent process runs idle due to material shortage, reducing the ineffective waiting time of the production line and thus improving the overall operating efficiency and equipment utilization of the bearing production line.

[0023] It should be noted that the bearing described in this application may be the outer ring of the bearing or the inner ring of the bearing.

[0024] In this utility model, the first conveying device 7 and the second conveying device 8 have the same structure, including a pneumatic gripper 21, a lateral movement mechanism 22 for driving the pneumatic gripper 21 to move laterally, and a lifting mechanism 23 for driving the bearings 10 stacked on the buffer vertical rod 6 to lift upward.

[0025] Specifically, the first conveying device 7 and the second conveying device 8 have identical structures. Both include pneumatic grippers 21, which can precisely grip the bearings 10; they also have a transverse movement mechanism 22, such as a synchronous belt module driven by a motor or a ball screw mechanism. The pneumatic grippers 21 are installed at the moving end of the transverse movement mechanism 22 and can move horizontally under the drive of the transverse movement mechanism 22. In addition, both are equipped with a lifting mechanism 23, which is set corresponding to the buffer vertical rod 6 and can apply an upward force to the bearings 10 stacked on the buffer vertical rod 6, so that the bearings 10 as a whole are lifted upward.

[0026] Taking the first conveying device 7 as an example, when it is necessary to convey the bearing 10 on the first conveyor belt 1 to the buffer vertical bar 6, the pneumatic gripper 21 moves to the bearing 10 on the first conveyor belt 1 and clamps it. Then, the lateral movement mechanism 22 drives the pneumatic gripper 21 to move above the buffer vertical bar 6. If there are already stacked bearings 10 on the buffer vertical bar 6, the lifting mechanism 23 is activated, lowering the existing bearings 10 a certain distance to make room. The pneumatic gripper 21 releases, and the bearings 10 are placed on the buffer vertical bar 6 and stacked sequentially.

[0027] When the second conveying device 8 is working, the lifting mechanism 23 lifts the bearings 10 stacked on the buffer vertical rod 6 upwards, so that the uppermost bearing 10 is in a position that is easy for the pneumatic gripper 21 to hold. After the pneumatic gripper 21 holds the bearing 10, the transverse mechanism 22 drives it to move above the second conveyor belt 3 and releases it.

[0028] In this utility model, the lifting mechanism 23 includes a lead screw module, a lifting plate 31 is provided on the movable seat of the lead screw module, and a support plate 32 is movably sleeved on the buffer vertical rod 6. The lifting plate 31 moves upward to lift the support plate 32.

[0029] The main body of the lifting mechanism 23 is a lead screw module, which consists of a motor, lead screw, nut seat, etc. The movable seat is a component that is fixedly connected to the nut seat. A lifting plate 31 is fixedly installed on the movable seat. The lifting plate 31 is flat. A support plate 32 is movably sleeved on the buffer vertical rod 6. The center of the support plate 32 has a through hole that matches the buffer vertical rod 6 and can support the bearings 10 stacked on the buffer vertical rod 6.

[0030] When it is necessary to lift the bearing 10 on the buffer vertical rod 6, the motor of the lead screw module starts, driving the lead screw to rotate, causing the nut seat and the moving seat to move upward, which in turn drives the lifting plate 31 to move upward. After the lifting plate 31 moves to contact the support plate 32, it continues to move upward to lift the support plate 32. The support plate 32 then drives the bearings 10 stacked on it to be lifted upward together. After reaching the required height, the motor stops running. When there is no need to lift, the motor reverses, the lifting plate 31 descends, and the support plate 32 descends together with the lifting plate 31 under the action of gravity.

[0031] See Figure 3 As shown, the lifting plate 31 is provided with a clearance notch 41 for avoiding the buffer vertical rod 6, and the lifting plate 31 can move to the bottom of the buffer vertical rod 6 along with the moving seat of the lead screw module.

[0032] Therefore, when the rotating disk 4 needs to rotate, the lifting plate 31 can be moved below the buffer vertical rod 6, so that the rotating disk 4 can drive the buffer vertical rod 6 to rotate smoothly.

[0033] See Figure 2As shown, a baffle 51 for blocking the movement of the bearing 10 is provided at the end of the first conveyor belt 1.

[0034] When the first conveyor belt 1 conveys the bearing 10, the bearing 10 moves forward with the conveyor belt. When it reaches the end of the first conveyor belt 1, the baffle 51 will block the bearing 10 from continuing to move, preventing the bearing 10 from falling off the end of the first conveyor belt 1 due to inertia, and ensuring that the bearing 10 stays at the designated position at the end of the first conveyor belt 1, so that the first conveying device 7 can accurately grasp it.

[0035] Guide bars 61 are provided at intervals on both the first conveyor belt 1 and the second conveyor belt 3.

[0036] When the bearing 10 is conveyed on the first conveyor belt 1 or the second conveyor belt 3, the guide bar 61 will limit the movement of the bearing 10 and prevent the bearing 10 from shifting in the width direction of the conveyor belt; the space between adjacent guide bars 61 is formed to accommodate a single bearing 10, so that the bearing 10 is kept in an orderly arrangement during the conveying process and avoids collision and squeezing with each other.

[0037] In this invention, the conveying end face of the first conveyor belt 1 is higher than the end face of the buffer vertical rod 6.

[0038] In terms of installation layout, the height of the conveying end face (i.e., the bearing surface of the conveyor belt) of the first conveyor belt 1 is set higher than the end face (i.e., the top end face of the buffer vertical rod 6). This height difference is achieved by adjusting the installation height of the first conveyor belt 1 frame and the buffer device 2, and is usually set to be less than the thickness of one bearing 10. Thus, the first conveying device 7 only needs to move the bearing 10 from a higher position to a lower position. During placement, the bearing 10 can be more smoothly fitted into the buffer vertical rod 6 by its own weight, reducing the difficulty of alignment during placement.

[0039] The end face of the buffer vertical rod 6 is higher than the conveying end face of the second conveyor belt 3.

[0040] After the second conveying device 8 picks up the bearing 10 from the buffer vertical rod 6, since the end face of the buffer vertical rod 6 is higher than the conveying end face of the second conveyor belt 3, when the second conveying device 8 conveys the bearing 10 to the second conveyor belt 3, the bearing 10 can be directly moved and placed on the second conveyor belt 3 by utilizing the height difference.
