Technical Field
[0001] This application belongs to the field of vibratory feeder manufacturing technology, specifically a vibratory feeder with limiting grooves and a center of gravity side-standing sorting function. Background Technology
[0002] like Figure 1 and Figure 2 As shown, when screening a workpiece 12 with a raised limiting groove 13 on one side of its front end, in order to facilitate the assembly of the workpiece 12 in the next station, the workpiece 12 needs to be output from the output end of the vibratory feeder in a specific shape. That is, to distinguish where the center of gravity of the workpiece (located on the workpiece 12 near the limiting groove 13) is located. Normally, the front of the workpiece 12 needs to be facing down, and the center of gravity of the workpiece needs to be distinguished to meet the requirements of the next station. However, existing vibratory feeders are mainly used for feeding nuts and screws, and cannot achieve the purpose of screening workpieces 12 with a limiting groove 13 on one side of their front end, thus failing to distinguish the center of gravity of the workpiece 12. Utility Model Content
[0003] The purpose of this application is to address the shortcomings of existing technologies by designing a vibratory feeder with a limiting groove and a center-of-gravity side-based sorting mechanism. This design involves sequentially arranging a first conveying spiral track, a product flipping and screening block, a horizontal-to-vertical switching mechanism, a connecting product flipping conveying spiral track, and an output spiral track on the inner circumference of the feeder body. This solves the problem of ensuring that the front of the workpiece faces down during output and that the workpiece is separated to meet the requirements of the next workstation when feeding workpieces with a protruding limiting groove at one end.
[0004] The above-mentioned technical objective of this application is achieved through the following technical solution: A vibratory feeder with limiting grooves and a center-of-gravity side-mounted sorting system includes a disc body with an internal horn shape. The inner diameter of the lower end of the disc body is smaller than the inner diameter of the upper end. The inner circumference of the disc body is provided with, from bottom to top, a first conveying spiral path, a product flipping and screening block, a horizontal-to-vertical switching mechanism, a product flipping and conveying spiral path, and an output spiral path. The lower end of the first conveying spiral path is located on the inner bottom surface of the disc body. The upper end of the first conveying spiral path is connected to the input end of the product flipping and screening block. The output end of the product flipping and screening block is connected to the input end of the horizontal-to-vertical switching mechanism. The output end of the horizontal-to-vertical switching mechanism is connected to the input end of the product flipping and conveying spiral path. The output end of the product flipping and conveying spiral path is connected to the input end of the output spiral path. The output end of the output spiral path extends outside the disc body.
[0005] Preferably, the product flipping and screening block is disposed on the inner side wall of the disc body, the side of the product flipping and screening block facing the inside of the disc body is flush with the inner side wall of the disc body, and the side of the product flipping and screening block facing the inside of the disc body is a rough surface.
[0006] Preferably, the horizontal-to-vertical switching mechanism includes a second conveying section and a slot section. The input end of the second conveying section is connected to the output end of the product flipping and screening block, and the output end of the second conveying section is connected to the input end of the slot section. The bottom of the slot section is lower than the conveying surface of the second conveying section facing the bottom of the disc body. The slot opening of the slot section faces the opening direction of the disc body. The end of the slot section facing away from the second conveying section is an output port, and the output port is connected to the conveying surface of the product flipping conveying spiral track.
[0007] Preferably, the product flipping conveyor spiral includes a third conveying section and a top block. The input end of the third conveying section is connected to the output port, and the output end of the third conveying section is connected to the input end of the output spiral. An extended conveying section is provided between the two ends of the third conveying section. The side of the extended conveying section facing away from the disc body extends into the inner wall of the disc body. The inner wall of the disc body is provided with a top block above the extended conveying section. The height of the side of the third conveying section facing the central axis of the disc body is higher than the height of the side of the third conveying section facing away from the central axis of the disc body. The distance between the lower end of the top block and the central axis of the disc body is greater than the distance from the side of the extended conveying section facing away from the central axis of the disc body to the central axis of the disc body. The distance between the lower end of the top block and the central axis of the disc body is greater than or equal to the radius of the cross section on the disc body at the same height as the lower end of the top block.
[0008] Preferably, the width of the output spiral path is equal to the width of the third conveying section.
[0009] Preferably, the input end of the output spiral channel is smoothly connected to the output end of the third conveying section. The output spiral channel gradually changes from an inclined state to a flat state from the input end to the output end. A baffle wall is provided on the side of the output spiral channel facing the central axis of the disk body, and a groove is provided between the baffle wall and the output spiral channel.
[0010] The beneficial effects of this application are: This application employs a design where a first conveying spiral channel, a product flipping and screening block, a horizontal-to-vertical switching mechanism, a connecting product flipping conveying spiral channel, and an output spiral channel are sequentially arranged from bottom to top on the inner circumference of the disc body.

[0013] like Figure 1-6 As shown, a vibratory feeder with limiting grooves and a center-of-gravity side-standing sorting system includes a disc body 1 with an internal horn shape. The inner diameter of the lower end of the disc body 1 is smaller than the inner diameter of the upper end. The inner circumference of the disc body 1 is provided with, from bottom to top, a first conveying spiral channel 2, a product flipping and screening block 3, a horizontal-to-vertical switching mechanism, a product flipping and conveying spiral channel, and an output spiral channel 9. The lower end of the first conveying spiral channel 2 is located on the inner bottom surface of the disc body 1. The upper end of the first conveying spiral channel 2 is connected to the input end of the product flipping and screening block 3. The output end of the product flipping and screening block 3 is connected to the input end of the horizontal-to-vertical switching mechanism. The output end of the horizontal-to-vertical switching mechanism is connected to the input end of the product flipping and conveying spiral channel. The output end of the product flipping and conveying spiral channel is connected to the input end of the output spiral channel 9. The output end of the output spiral channel 9 extends outside the disc body 1.
[0014] In this embodiment, during operation, several workpieces 12 are poured into the disc body 1, which is mounted on a vibrating machine (common knowledge). Then, under the action of vibration, the workpieces 12 move along the first conveying spiral channel 2 (as shown in the attached figure, and in actual applications, the width of the conveyed workpiece 12 is approximately equal to the width of the first conveying spiral channel 12, so horizontal workpieces 12 will not be conveyed by the first conveying spiral channel 12, but will fall directly back into the disc body 1) to the product flipping screening block 3. The product flipping screening block 3 shakes the workpieces 12 with their front facing the inner wall of the disc body 1 back into the disc body 1, while the workpieces 12 with their front facing away from the inner wall of the disc body 1 continue to move to the horizontal switching vertical mechanism. Then, the horizontal switching vertical mechanism stands the workpieces 12 upright, and the upright workpieces 12 continue to move to the product flipping conveying spiral channel for flipping, thus achieving the effect of the workpieces 12 facing down. The output is directed to the output spiral path 9, through which the workpiece 12 is output to the outside of the output disc body 1, thus solving the problem of how to make the front of the workpiece face down during output and distinguish the center of gravity side of the workpiece to meet the requirements of the next station.
[0015] As a preferred embodiment, the product flipping screening block 3 is disposed on the inner wall of the disc body 1, with the side of the product flipping screening block 3 facing inwards flush with the inner wall of the disc body 1, and the side of the product flipping screening block 3 facing inwards is rough. With this configuration, because the side of the product flipping screening block 3 facing inwards is rough, when the front of the workpiece 12 faces the product flipping screening block 3, the limiting groove 13 on the workpiece 12 will increase friction, preventing the workpiece 12 from moving forward, and the friction will cause more severe shaking. Since the side of the product flipping screening block 3 facing inwards is flush with the inner wall of the disc body 1, the workpiece 12 can only bounce off the product flipping screening block 3 and return to the disc body 1 under its own gravity and vibration (shaking). The back of the workpiece, touching the product flipping screening block 3, moves to the input end of the horizontal-to-vertical switching mechanism under the action of vibration and the funnel-shaped structural design inside the disc body 1.
[0016] In a preferred embodiment, the horizontal-to-vertical switching mechanism includes a second conveying section 4 and a slot section 5. The input end of the second conveying section 4 is connected to the output end of the product flipping and screening block 3, and the output end of the second conveying section 4 is connected to the input end of the slot section 5. The bottom of the slot section 5 is lower than the conveying surface of the second conveying section 4 facing the bottom of the disc body 1. The opening of the slot section 5 faces the opening direction of the disc body 1. The end of the slot section 5 facing away from the second conveying section 4 is the output port 6, which is connected to the conveying surface of the product flipping conveyor spiral track. With this design, the workpiece 12 is conveyed from the product flipping and screening block 3 to the second conveying section 4. Then, the end of the workpiece 12 without the limiting groove 13 is inserted into the slot opening of the slot section 5 under gravity, thus converting the horizontal workpiece 12 into a vertical position. At this time, the front of the workpiece 12 (the side with the limiting groove 13) faces the inside of the disc body 1. It is then conveyed from the output port 6 to the product flipping conveyor spiral track.
[0017] As a preferred embodiment, the product flipping conveyor spiral includes a third conveying section 7 and a top block 8. The input end of the third conveying section 7 is connected to the output port, and the output end of the third conveying section 7 is connected to the input end of the output spiral duct 9. An extended conveying section 14 is provided between the two ends of the third conveying section 7. The side of the extended conveying section 14 facing away from the disc body 1 extends into the inner wall of the disc body 1. The inner wall of the disc body 1 has a top block 8 above the extended conveying section 14. The height of the side of the third conveying section 7 facing the central axis of the disc body 1 is higher than the height of the side of the third conveying section 7 facing away from the central axis of the disc body 1. The distance between the lower end of the top block 8 and the central axis of the disc body 1 is greater than the distance from the side of the extended conveying section 14 facing away from the central axis of the disc body 1 to the central axis of the disc body 1 (this arrangement is necessary to achieve the purpose of flipping the workpiece 12 during conveying). The distance between the lower end of the top block 8 and the central axis of the disc body 1 is greater than or equal to the radius of the cross section of the disc body 1 at the same height as the lower end of the top block 8. With this configuration, due to the extended conveyor section 14, under the influence of gravity, the end of workpiece 12 without the limiting groove 13 will move towards the side of the extended conveyor section 14 facing away from the central axis of the disk body 1. The top block 8 pushes the end of workpiece 12 without the limiting groove 13 towards the central axis of the disk body 1, thus flipping workpiece 12 so that its front is facing down and the end with the limiting groove 13 faces towards the central axis of the disk body 1. The distance between the lower end of the top block 8 and the central axis of the disk body 1 is greater than or equal to the radius of the cross-section of the disk body 1 at the same height as the lower end of the top block 8, preventing the top block 8 from pushing workpiece 12 into the disk body 1. The height of the side of the third conveyor section 7 facing the axis of the disk body 1 is higher than the height of the side of the third conveyor section 7 facing away from the axis of the disk body 1. This configuration ensures that during conveying, a portion of the gravity force on workpiece 12 is directed towards the inner wall of the disk body 1, thus preventing workpiece 12 from falling back into the disk body 1.
[0018] As a preferred embodiment, the width of the output spiral path 9 is equal to the width of the third conveying section 7. With this configuration, during use, the length of the portion of the conveyed workpiece 12 without the limiting groove 13 is equal to the width of the third conveying section 7. This ensures that the limiting groove 13 is located on the outer side of both the output spiral path 9 and the third conveying section 7 facing the center of the disk body 1. This allows the front surface of the workpiece 12 to be in close contact with the conveying surfaces of both the third conveying section 7 and the output spiral path 9, preventing any further changes in the state of the workpiece 12.
[0019] As a preferred embodiment, the input end of the output spiral channel 9 is smoothly connected to the output end of the third conveying section 7. The output spiral channel 9 gradually changes from an inclined state to a flat state from the input end to the output end. A baffle 10 is provided on the side of the output spiral channel facing the central axis of the disk body 1. A groove 11 is provided between the baffle 10 and the output spiral channel 9. With this configuration, the baffle 10 prevents the workpiece 12 from falling into the disk body 1, and the groove 11 acts as a clearance, allowing the groove 11 to make way for the limiting groove 13 on the workpiece 12 during the conveying process. This ensures that the part of the workpiece 12 without the limiting groove 13 is in close contact with the conveying surface of the output spiral channel 9.
[0020] Ultimately, regardless of its state, after the workpiece 12 is conveyed by the vibratory feeder of this application, the output state of the workpiece 12 is face down, with its center of gravity facing the axis of the feeder body 1. That is, the end of the workpiece 12 with the limiting groove 13 faces the axis of the feeder body 1, while the end without the limiting groove 13 faces away from the axis of the feeder body 1. This output certainty facilitates processing or assembly at the next workstation.
