Description

Technical Field

[0001] The utility model relates to the automatic feeding of parts, and particularly relates to a feeding mechanism applicable to small cylindrical parts. Background Art

[0002] At present, when automatically detecting small cylindrical parts (such as small pistons), the common feeding methods mainly include the following three: 1. Using a sorting mechanism turntable to feed one by one; 2. Using a manipulator to grab and feed one by one; 3. Using a conveyor belt or conveyor to set a limiting plate to feed one by one.

[0003] When using a sorting turntable, the workpieces are sent out one by one by relying on centrifugal force, and the efficiency is not high. It is not easy to separate the workpieces after they are easily stacked. Using a manipulator to grab has a relatively high cost and strict requirements for the placement of workpieces. Using the method of a conveyor and a limiting plate, the feeding is prone to form a stable triangular structure, and the stacking and blocking of materials are serious. Manual intervention is often required, which brings inconvenience to the production site. Summary of the Utility Model

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0027] As Figures 1 to 3 shown, this embodiment provides a feeding mechanism applicable to small cylindrical parts, including a belt conveyor 10, and a guiding mechanism 20, a feeding channel 30 and a workpiece pushing mechanism 40 are sequentially arranged on the belt conveyor 10 along the part conveying direction.

[0028] The guiding mechanism includes an inclined guiding plate 1 and a guard plate 2 extending linearly along the conveying direction. The guiding plate 1 is fixedly connected to one side of the frame of the belt conveyor 10 through a support frame 5, and the guard plate 2 is fixed to the other side of the frame of the belt conveyor 10. A guiding opening with a large end and a small end is formed between the guiding plate 1 and the guard plate 2, and the small end of the guiding opening is communicated with the feeding channel 20.

[0029] The feeding channel includes a feeding guide plate 4 extending linearly along the conveying direction. The feeding guide plate 4 is fixed on the support frame 5, and a feeding channel is formed between the feeding guide plate 4 and the guard plate 2. The feeding channel is a channel for the movement of a single workpiece. This channel can be adjusted as needed to meet the use of parts of various specifications.

[0030] The guiding plate 2 is provided with a pushing mechanism 50 near the feeding channel. The pushing mechanism 50 includes a pushing plate 6. One end of the pushing plate 6 is provided with a hinge point, and the pushing plate 6 is rotatably connected to the support frame 5 through the hinge point; at the same time, the pushing plate 6 is connected with a driving unit, and the driving unit drives the pushing plate 6 to rotate around the hinge point.

[0031] The driving unit includes a cylinder fixed base 7 and a swing cylinder 8. The cylinder fixed base 7 is fixed on the support frame 5. One end of the swing cylinder 8 is rotatably connected to the cylinder fixed base 7, and the other end of the swing cylinder 8 is rotatably connected to the pushing plate through a spherical plain bearing.

[0032] In this embodiment, the hinge point is located at the connection of the guiding plate 1 and the feeding guide plate 4. A hinge 9 is provided at the hinge point, and the pushing plate 6 is rotatably connected to the support frame 5 through the hinge 9.

[0033] During operation, the swing cylinder 8 extends and retracts to drive the pushing plate 6 to rotate a specific angle around the hinge 9. This swing angle is crucial and directly affects whether the stacked workpieces can be pushed away normally.

[0034] A travel stopper 3 is fixedly provided on the guard plate 2 at a position corresponding to the pushing mechanism. In actual use, more than two travel stops 3 need to be provided.

[0035] The inner sides of the guide plate 1, the push plate 14, the feed guide plate 4 and the guard plate 2 are all fixedly provided with nylon baffles 60, which can effectively prevent the workpiece from being scratched.

[0036] The pushing direction of the workpiece pushing mechanism 40 is perpendicular to the conveying direction of the belt conveyor 10 , and an optical fiber sensor 41 is provided on the workpiece pushing mechanism 40 , and the optical fiber sensor 41 is used to detect that a part enters the area of ​​the workpiece pushing mechanism.

[0037] The working principle of the utility model is as follows:

[0038] (1) Normal feeding

[0039] The workpieces are piled up on the flat belt conveyor 10, and the conveyor motor rotates forward to guide the workpieces into the guide plate 1. The guide plate 1 has a nylon baffle to effectively prevent the workpieces from being scratched. The workpieces are pressed against the guide plate 3 and move along a specific angle to the mouth of the feeding channel 20. The channel mouth allows a single workpiece to pass through. The workpieces are pressed against the channel one by one and move along the normal conveying direction. When the workpieces move to the optical fiber sensor 41, the belt motor stops rotating, and the workpiece pushing mechanism 40 pushes the workpiece at the head end to the specified feeding grabbing position.

[0040] (2) Removal of workpiece accumulation

[0041] When the optical fiber sensor 41 does not sense the workpiece within 4-5 seconds, the material jam release program starts to run. First, the motor reverses for 2s to withdraw the accumulated workpiece from the accumulation position as a whole. When the workpiece contacts the travel block 3, the workpiece is displaced and moves toward the direction close to the guide plate 1. Due to the action of the travel block 3, the area of ​​the accumulated workpiece will be broken up, and at the same time, the pushing mechanism controls the push plate 6 to push out once, and then the motor runs normally to send the accumulated workpiece to the feeding channel, and the accumulated state is automatically contacted.

[0042] For products of different specifications, the guide plate 1 and the travel block 3 can be adjusted in position to meet the feeding requirements of workpieces of different specifications.

[0043] On the basis of the belt conveyor 10, the utility model adds a push plate mechanism 50 and a travel block 3. The push plate mechanism 50 needs to swing to a specific angle to cooperate with the travel block 3. Without adding an additional power mechanism, the accumulated workpieces can be efficiently separated, the problem of workpiece accumulation on site can be solved, the continuous and normal operation of the automation equipment can be ensured, and the utilization rate of the detection equipment can be improved.

[0044] The utility model has a simple structure, is stable and reliable, and is very suitable for the batch automatic feeding of such small piston parts.
