Description

Technical Field

[0001] This application relates to the field of material transfer mechanism technology, specifically to a rotating feeding device with adjustable lifting height. Background Technology

[0002] With the development of material handling technology, loading devices such as robotic arms are becoming increasingly common. For large, disc-shaped materials, it is difficult to use forklifts or robotic arms for loading, thus requiring a loading device suitable for disc-shaped materials. Typically, the chassis used to hold disc-shaped materials is fixed. Even with grippers, it is difficult to handle disc-shaped materials of varying thicknesses. Even with lifting cylinders added to the bottom of the disc to adjust its height, the weight of large discs limits the cylinder's stroke for safety reasons, preventing a significant increase in the disc's height and making it unsuitable for loading large quantities of disc-shaped materials of different thicknesses. Summary of the Invention

[0003] This application provides a lifting adjustable rotating feeding device, which can solve the current technical problem that it is impossible to significantly increase the height of large disc-shaped materials to adapt to the gripper gripping the disc-shaped materials and realize the feeding of disc-shaped materials of different thicknesses.

[0004] This application provides an adjustable-height rotary feeding device, which includes a central body, a feeding mechanism, a rotating device, and a clamping device. The central body is vertically fixed on a fixed foundation. A limiting ring and a limiting ring lifting device are provided on the outer side of the central body. The limiting ring lifting device is fixed to the outer side of the central body and connected to the limiting ring. The limiting ring lifting device can control the lifting and lowering of the limiting ring on the outer side of the central body. The clamping device is supported on the limiting ring and rotates circumferentially along the central body. The rotating device includes a drive gear and a drive motor. The middle part of the drive gear is connected to the output shaft of the drive motor. The drive motor is located below the clamping device. The bottom of the clamping device includes a driven gear plate. The drive gear meshes with the driven gear plate. The rotation of the drive gear drives the driven gear plate to rotate so that the clamping device is rotatably connected to the rotating device. The thickness of the driven gear plate is greater than the thickness of the drive gear. When the limiting ring drives the clamping device to rise and fall relative to the intermediate body, the drive gear and the driven gear plate are always kept meshed.

[0005] Furthermore, the rotating device is connected to the feeding mechanism, which is fixed to the outside of the intermediate body.

[0006] Furthermore, the feeding mechanism includes a fixed base, a transverse cylinder, a lifting cylinder, and a feeding tray. The intermediate main body is disposed inside the fixed base. One side of the fixed base is connected to the transverse cylinder. The lifting cylinder is disposed on the transverse cylinder, and the feeding tray is disposed on the lifting cylinder.

[0007] Furthermore, the feeding mechanism also includes a side support plate and a position sensor. The two ends of the side support plate are respectively connected to the intermediate main body and the lifting cylinder, and the position sensor is located on both sides of the feeding tray.

[0008] Furthermore, the clamping device also includes a jaw and a jaw drive structure. The driven gear is annular, and the inner side of the driven gear meshes with the drive gear. The jaw drive structure is fixed on the driven gear, and the jaw is connected to the jaw drive structure.

[0009] Furthermore, the feeding mechanism includes a receiving base and a pressing cover, the pressing cover being lifted and positioned above the receiving base, and the receiving base being positioned adjacent to the rotating device.

[0010] Furthermore, the pressure cover includes a support column, a lifting drive structure, and a cover body. The support column passes through the middle of the driven gear plate and is connected to the fixed base. The lifting drive structure is located on one side of the support column, and the cover body is connected to the lifting drive structure.

[0011] Furthermore, the intermediate body also includes a feeding mechanism. The feeding mechanism and the feeding mechanism are respectively located on both sides of the rotating device. The material is conveyed to one side of the rotating device by the feeding mechanism. The rotating device drives the clamping device to be set up corresponding to the feeding mechanism to clamp the material on the feeding mechanism. After the rotating device drives the clamping device to rotate a first angle, it is set up corresponding to the feeding mechanism to place the material on the feeding mechanism.

[0012] Furthermore, the first angle is one of 180 degrees, 90 degrees, 60 degrees, or 45 degrees.

[0013] The adjustable-lift rotary feeding device provided in this application includes a central body, a feeding mechanism, a rotating device, and a clamping device. The rotating device includes a drive gear and a drive motor. The middle part of the drive gear is connected to the output shaft of the drive motor. The drive motor is located below the clamping device. The bottom of the clamping device includes a driven gear plate. The drive gear meshes with the driven gear plate to rotatably connect the clamping device to the rotating device. The thickness of the driven gear plate is greater than the thickness of the drive gear. The outer side of the intermediate main body is provided with a limiting ring and a limiting ring lifting device. The limiting ring lifting device is fixed on the outer side of the intermediate main body and is connected to the limiting ring.

[0026] For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 This application provides an adjustable-lift rotary feeding device, which includes a central body 5, a feeding mechanism 1, a rotating device 2, and a clamping device 3. The central body 5 is vertically fixed on a fixed base. A limiting ring 51 and a limiting ring lifting device 52 are provided on the outer side of the central body 5. The limiting ring lifting device 52 is fixed on the outer side of the central body 5 and connected to the limiting ring 51. The limiting ring lifting device 52 can control the lifting and lowering of the limiting ring 51 on the outer side of the central body 5. The clamping device 3 is supported on the limiting ring 51 and rotates circumferentially along the central body 5. The rotating device 2... The clamping device 3 includes a drive gear 21 and a drive motor 22. The middle part of the drive gear 21 is connected to the output shaft of the drive motor 22. The drive motor 22 is located below the clamping device 3. The bottom of the clamping device 3 includes a driven gear disk 31. The drive gear 21 is meshed with the driven gear disk 31. The rotation of the drive gear 21 drives the driven gear disk 31 to rotate so that the clamping device 3 is rotatably connected to the rotating device 2. The thickness of the driven gear disk 31 is greater than the thickness of the drive gear 21. When the limiting ring 51 drives the clamping device 3 to rise and fall relative to the intermediate body 5, the drive gear 21 and the driven gear disk 31 are always meshed.

[0027] In this embodiment, a limiting ring 51 and a limiting ring lifting device 52 are provided on the outer side of the intermediate main body 5. The limiting ring lifting device 52 is fixed on the outer side of the intermediate main body 5 and is connected to the limiting ring 51. The limiting ring lifting device 52 can control the lifting and lowering of the limiting ring 51 on the outer side of the intermediate main body 5. When the limiting ring 51 drives the clamping device 3 to lift and lower relative to the intermediate main body 5, the driving gear 21 is always engaged with the driven gear 31. This allows for up-and-down adjustment of the position of the clamping device 3, enabling the feeding of disc-shaped materials of different thicknesses and accurately enabling the clamping device 3 to grip the disc-shaped materials on the feeding mechanism 1.

[0028] like Figure 1 As shown, the rotating device 2 is connected to the feeding mechanism 1, and the feeding mechanism 1 is fixed to the outside of the intermediate body 5.

[0029] like Figure 2 As shown, the drive motor 22 drives the drive gear 21 to rotate, and the rotation of the drive gear 21 drives the driven gear disk 31 to rotate. The rotation of the driven gear disk 31 drives the clamping device 3 to rotate. By controlling the rotation angle of the drive gear 21 according to the ratio of the number of teeth of the drive gear 21 to the number of teeth of the driven gear disk 31, the rotation angle of the clamping device 3 can be accurately controlled.

[0030] like Figure 1 As shown, the feeding mechanism 1 includes a fixed base 11, a transverse cylinder 12, a lifting cylinder 13, and a feeding tray 14. The intermediate main body 5 is disposed inside the fixed base 11. One side of the fixed base 11 is connected to the transverse cylinder 12. The lifting cylinder 13 is mounted on the transverse cylinder 12, and the feeding tray 14 is mounted on the lifting cylinder 13. When the material is placed on the feeding tray 14, the transverse cylinder 12 can be controlled to extend and retract to adjust the horizontal position of the material. The vertical position of the material can be adjusted by controlling the lifting cylinder 13 to drive the feeding tray 14 to rise and fall. The lifting cylinder 13 and the limiting ring lifting device 52 work together to increase or decrease the distance between the clamping device 3 and the feeding tray 14 of the feeding mechanism 1, which is suitable for feeding disc-shaped materials of different thicknesses.

[0031] like Figure 1 As shown, the feeding mechanism 1 also includes a side support plate 15 and a position sensor 16. The two ends of the side support plate 15 are respectively connected to the intermediate main body 5 and the lifting cylinder 13, and the position sensor 16 is located on both sides of the feeding tray 14.

[0032] like Figure 2As shown, the clamping device 3 further includes a gripper 32 and a gripper drive structure 33. The driven gear disk 31 is annular, and its inner side meshes with the drive gear 21. The gripper drive structure 33 is fixed on the driven gear disk 31, and the gripper 32 is connected to the gripper drive structure 33. The gripper drive structure 33 can drive the gripper 32 to open or close, thereby gripping and releasing materials.

[0033] like Figure 2 , Figure 5 As shown, the gripper 32 includes a first gripper arm 321 and a second gripper arm 322 disposed opposite to each other. The root portions of the first gripper arm 321 and the second gripper arm 322 are respectively provided with a first inclined guide groove 323 and a second inclined guide groove 324. The first inclined guide groove 323 and the second inclined guide groove 324 are V-shaped. The gripper driving structure 33 includes a guide pushing block 331. The guide pushing block 331 has a first inclined guide block 332 and a second inclined guide block 333 on both sides. The first inclined guide block 332 and the second inclined guide block 333 are V-shaped. The first inclined guide block 332 is slidably connected to the first inclined guide groove 323, and the second inclined guide block 333 is slidably connected to the second inclined guide groove 324. When the guide pushing block 331 moves, it drives the first gripper arm 321 and the second gripper arm 322 located on both sides of the guide pushing block 331 to open or clamp.

[0034] like Figure 5 As shown, the gripper drive structure 33 also includes a translation drive structure connected to the guide push block 331. The translation drive structure includes a linear motor or a horizontal cylinder. By driving the guide push block 331 to move in the horizontal plane through the translation drive structure, the first gripper arm 321 and the second gripper arm 322 located on both sides of the guide push block 331 can be opened or clamped.

[0035] like Figure 1 , Figure 2 As shown, the feeding mechanism 1, the rotating device 2 and the unloading mechanism 4 are arranged in a straight line, and two clamping jaws 32 are symmetrically arranged on both sides of the clamping device 3.

[0036] like Figure 1 As shown, the feeding mechanism 4 includes a receiving base 41 and a pressing cover 42. The pressing cover 42 is detachably positioned above the receiving base 41, and the receiving base 41 is located adjacent to the rotating device 2. When material is transferred from the clamping device 3 to the feeding mechanism 4, the receiving base 41 can receive the material, and the pressing cover 42 can press the material onto the receiving base 41.

[0037] like Figure 1 , Figure 3 As shown, the pressure cover 42 includes a support column 421, a lifting drive structure 422, and a cover body 423. The support column 421 passes through the middle of the driven gear plate 31 and is connected to the fixed base 11. The lifting drive structure 422 is located on one side of the support column 421, and the cover body 423 is connected to the lifting drive structure 422.

[0038] like Figure 1 As shown, the adjustable lifting rotating feeding device also includes a discharging mechanism 4. The feeding mechanism 1 and the discharging mechanism 4 are respectively located on both sides of the rotating device 2. The material is conveyed to one side of the rotating device 2 by the feeding mechanism 1. The rotating device 2 drives the clamping device 3 to be positioned corresponding to the feeding mechanism 1 to clamp the material on the feeding mechanism 1. After the rotating device 2 drives the clamping device 3 to rotate by a first angle, it is positioned corresponding to the discharging mechanism 4 to place the material on the discharging mechanism 4. The feeding mechanism 1 and the discharging mechanism 4 are respectively located on both sides of the rotating device 2, realizing that after the material is clamped by the clamping device 3 from the feeding mechanism 1, it is rotated by a first angle and placed on the discharging mechanism 4. This realizes the corner picking and placing of materials. The rotating device 2 can precisely control the rotation angle of the clamping device 3 to control the material rotation before feeding, and reduces equipment costs.

[0039] Furthermore, the first angle is one of 180 degrees, 90 degrees, 60 degrees, and 45 degrees. It is understood that the first angle is preferably achieved by setting 2n grippers 32 on both sides of the clamping device 3, where n is an integer. Each pair of grippers 32 corresponds to one feeding mechanism 1 and one unloading mechanism 4, so that the grippers 32 are evenly distributed on the side of the clamping device 3. Thus, the first angle of rotation of the clamping device 3 by the rotating device 2 each time is 360 / 2n, which is one of 180 degrees, 90 degrees, 60 degrees, and 45 degrees.

[0040] The adjustable-lift rotary feeding device provided in this application includes a feeding mechanism 1, a rotating device 2, a clamping device 3, and a discharging mechanism 4. The rotating device 2 includes a drive gear 21, and the bottom of the clamping device 3 includes a driven gear 31. The drive gear 21 and the driven gear 31 are meshed and connected so that the clamping device 3 is rotatably connected to the rotating device 2. The feeding mechanism 1 and the discharging mechanism 4 are respectively located on both sides of the rotating device 2. After the material is clamped by the clamping device 3 from the feeding mechanism 1, it is rotated at a first angle and placed on the discharging mechanism 4. This realizes the rotation angle picking and placing of materials, and the rotation angle of the clamping device 3 can be precisely controlled by the rotating device 2 to control the material rotation before feeding, thereby reducing equipment costs.
