Description

Technical Field

[0001] This utility model relates to a vibratory feeder, specifically a vibratory feeder for automatic feeding of cylindrical sleeves. Background Technology

[0002] In early industrial production, the supply of cylindrical sleeves largely relied on manual sorting and loading. This process not only consumed a lot of manpower and time, but the repetitive work of workers over long periods of time easily led to fatigue, resulting in low supply efficiency and difficulty in ensuring accuracy. Moreover, due to human error, sleeves of the wrong specifications were often placed, affecting product quality.

[0003] With the development of automation technology, general vibratory feeder devices have gradually become widely used. These vibratory feeders typically consist of a chassis, side walls, and a built-in spiral track, with a vibratory motor installed below the chassis. During operation, the vibratory motor drives the chassis to generate high-frequency vibrations, causing the material placed at the beginning of the spiral track to gradually rise along the track under the combined action of the inertial force generated by the vibration and gravity. The principle is to use vibration to impart an upward-sloping force to the material, overcoming gravity and causing it to rise along the track, much like pushing an object forward on a constantly shaking slope. For simple parts with regular shapes and stable centers of gravity, such as ordinary bolts and nuts, this feeding method can achieve a certain degree of automated continuous feeding, greatly improving production efficiency. However, it reveals many problems when dealing with materials with special shapes and rolling characteristics, such as cylindrical sleeves. Summary of the Invention

[0004] To address the aforementioned problems, this utility model provides a vibratory feeder for automatic feeding of cylindrical sleeves. This vibratory feeder feeding device can efficiently and accurately output cylindrical sleeves with their openings facing upwards, solving the problems of low efficiency and unstable posture of existing vibratory feeders when handling cylindrical sleeves, thereby improving the automation level and production efficiency of industrial production lines.

[0005] This utility model is achieved through the following technical solution: a vibratory feeder for automatic feeding of cylindrical sleeves, comprising:

[0006] The vibrating chassis is equipped with a vibrating motor to generate high-frequency vibration;

[0007] A spiral track, arranged in a spiral shape and provided with sidewalls, is set on the vibrating chassis to guide the cylindrical sleeve to be conveyed upward along the track;

[0008] A material screening and attitude adjustment device is set in the middle or end area of ​​the spiral track. It includes multiple baffles, notches and serrated texture structure, and is used to screen and adjust the attitude of the cylindrical sleeve so that it is finally output in an open-up state.

[0009] The discharge track, located at the end of the spiral track, is used to output the cylindrical sleeve after attitude adjustment;

[0010] The control system is used to control the vibration frequency and amplitude of the vibrating motor and receive sensor feedback to adjust the vibration parameters, thereby achieving stability and continuity in the feeding process.

[0011] As a preferred technical solution, the material screening and attitude adjustment device includes an arc-shaped baffle for guiding the sleeves to queue up and enter the next area.

[0012] As a preferred technical solution, the material screening and attitude adjustment device further includes a guide plate and a first side baffle plate connected to the output end of the guide plate, for partially adjusting the attitude of the sleeve opening facing upwards, and the guide plate and the first side baffle plate are arranged in the spiral track.

[0013] As a preferred technical solution, the material screening and attitude adjustment device further includes a second side baffle plate disposed within the spiral track. The inner side of the second side baffle plate forms a discharge port, and the bottom surface of the discharge port is located on one side of the arc-shaped baffle plate to form a discharge port for screening horizontally oriented sleeves and returning them to the chassis area for re-screening.

[0014] As a preferred technical solution, the material screening and attitude adjustment device further includes a serrated pattern, which is used to cause the downward-facing sleeve to lose balance and fall back into the vibratory plate.

[0015] As a preferred technical solution, the Teflon coating on the discharge track has a friction coefficient of less than 0.1.

[0016] As a preferred technical solution, the surface of the discharge track is provided with transverse microgrooves to reduce material adhesion and disrupt the vacuum adsorption effect.

[0017] The beneficial effects of this utility model are: The vibratory feeder for automatic feeding of cylindrical sleeves provided by this utility model, by setting up a multi-level structure for screening and posture adjustment, including arc baffle, integrated baffle, notch structure and sawtooth pattern, can effectively screen out sleeves with incorrect posture, so that the sleeves at the output end are all arranged with the opening facing upward, thus improving the feeding accuracy.

[0018] The discharge track structure, which is coated with Teflon and processed with transverse microgrooves, significantly reduces friction and adhesion, prevents the sleeve from getting stuck in the track due to vacuum adsorption, and improves the smoothness of discharge.

[0019] By combining sensors and a control system to adjust the vibration frequency and amplitude in real time, the adaptability of the equipment and the stability of feeding are enhanced under different material conditions.

[0020] This device is particularly suitable for precise feeding of easily rolling workpieces such as cylindrical sleeves. It overcomes the problem of insufficient attitude control capability of traditional vibratory feeders and improves the overall operating efficiency and product quality consistency of automated assembly lines.

[0027] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0028] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0029] like Figures 1-3 As shown, the vibratory feeder of this utility model for automatic feeding of cylindrical sleeves has a compact overall structure and is suitable for directional conveying and feeding of cylindrical sleeve-type parts in industrial automated assembly. The vibratory feeder mainly includes a vibratory base 1, a spiral track 4, a material screening and attitude adjustment device, a discharge track, and a control system, among other structural components.

[0030] The vibrating chassis 1 is located at the bottom of the equipment and has a circular structure. A vibrating motor is installed at its bottom. The vibrating motor operates under the drive of the control system and can generate high-frequency vibration, causing the entire chassis to vibrate slightly in the horizontal and vertical directions. This causes the material placed on the chassis to move upward due to inertia, providing a power source for subsequent material conveying.

[0031] The spiral track 4 is fixedly installed on the upper surface of the vibrating chassis 1. The track rises layer by layer along the circumference to form a spiral channel. The width and height of the spiral track 4 are customized according to the outer diameter and height of the cylindrical sleeve, and side wall structures are provided on both sides to prevent the sleeve from falling off laterally during vibration and to ensure that the sleeve can move stably upward along the track.

[0032] To achieve the screening and adjustment of the sleeve's posture, a material screening and posture adjustment device is arranged in the middle to end area of ​​the spiral track 4. This device includes multiple baffles, notched structures, and serrated texture 9 structures. Specifically, an arc-shaped baffle 8 is set on one side of the track. This arc-shaped baffle 8 is used to guide the rising sleeves to smoothly transition and queue up one by one to enter the next area, forming a preliminary screening.

[0033] After the arc-shaped baffle 8, a guide plate 2 and a first side baffle 3 connected to its end are provided. The two work together to form a guide structure, which causes the sleeves that rise in a non-opening upward posture to roll and adjust here, thereby increasing the proportion of those that pass through in an open-up manner.

[0034] Continuing forward, a second side baffle 5 is set on the other side of the spiral track 4. The inner side of the baffle forms a drop port 7. When the sleeve passes through this area in a horizontal orientation, it will fall from the drop port 7 due to gravity. The bottom of the drop port 7 is connected to a discharge port 6, which can guide the fallen sleeve back to the vibrating chassis 1, so that it can participate in the orientation screening process again, thereby improving the consistency and reliability of the overall material supply.

[0035] Furthermore, a serrated texture 9 structure is provided at the end area of ​​the screening device. The serrated texture 9 is arranged on the bottom surface of the track, and its top has an irregular peak and trough shape. When the sleeve enters this area with its opening facing down and passes through the serrated texture 9, it will roll or lose balance due to uneven force, and then roll back from the gap to the vibrating chassis 1 area, thereby achieving further rejection of the opening-facing sleeve.

[0036] The end of the spiral track 4 is equipped with a discharge track, which serves as the final output channel for the qualified posture sleeve. To improve discharge efficiency and prevent adhesion and jamming, the surface of the discharge track is coated with a Teflon coating. This coating has an extremely low coefficient of friction, less than 0.1, thereby effectively reducing the sliding resistance between the sleeve and the track surface.

[0037] Meanwhile, to further prevent vacuum adsorption between the smooth surface and the sleeve, which could lead to sleeve stagnation or poor conveying, regularly arranged transverse microgrooves 10 are machined on the surface of the discharge track. This groove structure can effectively disrupt the vacuum adsorption effect, promote the smooth sliding of the sleeve out of the track, and ensure smooth connection of subsequent processes.

[0038] The entire vibratory feeder system is equipped with a control system, which includes a set of vibration parameter control modules and sensor components. The sensors can monitor the movement of materials in the track in real time and feed the detection signals back to the control module. The control module automatically adjusts the frequency and amplitude of the vibratory motor based on the feedback data, ensuring continuous and stable operation during the feeding process, unaffected by material batches, friction conditions, or differences in center of gravity distribution, thereby improving the stability and adaptability of the entire feeding system.

[0039] Through the above structural design and combination, this utility model can effectively achieve efficient feeding of cylindrical sleeves in an automatic, oriented and uniform manner, and is suitable for industrial scenarios such as assembly and processing in various automated production lines, significantly improving production efficiency and product consistency.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
