Abstract

This invention relates to a bearing conveying and discharging device and its working method. The discharging device is located at the junction of a dropping guide rail and a discharging guide rail, and includes a mounting plate, a track, a slider, a base plate, a push rod, a connecting rod assembly, a rotating wheel, a motor, and a blocking mechanism. The mounting plate fixes the track, the slider is slidably connected to the track, and the base plate is fixed to the slider and connected to the push rod. One end of the connecting rod assembly is connected to the base plate, and the other end is eccentrically connected to the rotating wheel. The motor drives the rotating wheel to drive the connecting rod assembly, causing the push rod to reciprocate along the discharging guide rail. The blocking mechanism includes a bracket, a lifting rod, a swing rod assembly, a top rod, and a top rod seat. Initially, the lifting rod blocks the outlet of the dropping guide rail. The top rod, following the movement of the push rod, pushes the swing rod assembly to swing, causing the lifting rod to rise and release the obstruction. When the top rod resets, the lifting rod falls back to restore the obstruction. This design, through the linkage of the blocking mechanism and the push rod, ensures stable and reliable bearing discharging.

Description

Technical Field

[0001] This invention relates to the field of bearing production line conveying, and is a bearing conveying and discharging device and its working method. Background Technology

[0002] In bearing manufacturing production lines, various compatible conveyor tracks are often involved to meet the bearing condition requirements during actual processing or testing. The transition between workstations, especially at corners, is particularly challenging, demanding high reliability and stability. The goal is to avoid damaging the bearing while ensuring smooth transitions. Existing bearing feeding devices, such as the utility model "A Feeding Device for a Bearing Production Line" (authorization announcement number CN217126052U, authorization announcement date August 5, 2022), disclose a pushing mechanism. This mechanism mainly includes multiple sets of cylinders and a pusher block structure. The fixed stroke of the cylinders enables the pusher block to move in the corresponding stroke and direction, fulfilling the requirements for conveying during workstation transitions. While this structure achieves feeding and conveying, the overall design and control remain complex, requiring coordinated operation of the cylinders to ensure reliable conveying. In addition, this equipment is mainly suitable for applications where the bearing conveying position has a small height difference. If the bearing conveying position has a large height difference, such as when the bearing rolls from a high place to a low place, relying solely on the V-shaped chute for receiving the material is insufficient for reliable material receiving. Appropriate blocking structures are required, and the blocking time interval must be matched with the pushing time interval of the pushing operation; otherwise, reliable pushing and discharging operations are difficult to achieve. Existing technologies also disclose solutions using electromagnets in conjunction with relays to achieve intermittent blocking. However, the timed blocking of the electromagnet and the intermittent pushing of the cylinder are still independently controlled, requiring adjustment after a period of use. Otherwise, long-term consistency cannot be guaranteed, and if one malfunctions while the other fails to stop in time, it can easily lead to bearing conveying errors, making subsequent adjustments and solutions quite troublesome. Therefore, a bearing conveying and discharging device that integrates blocking and pushing is needed. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the purpose of this invention is to provide a bearing conveying and discharging device and its working method, thereby solving the technical problem that existing bearing conveying and discharging devices, when changing work positions, fail to effectively coordinate the bearing blocking and pushing actions, making it difficult to ensure the consistency of their operation and affecting the stability and reliability of bearing conveying. This objective is achieved through the following technical solution.

[0004] A bearing conveying and discharging device is disposed at the junction of a dropping guide rail and a discharging guide rail. Its key structural features include a mounting plate, a track, a slider, a base plate, a push rod, a connecting rod assembly, a rotating wheel, a motor, and a blocking mechanism. The mounting plate is fixed relative to the dropping and discharging guide rails. The track is fixed to the upper surface of the mounting plate. The slider is slidably disposed on the track. The base plate is fixed to the slider. The push rod is fixed to the base plate. One end of the base plate is fixed to a first rotating shaft, which is shaft-connected to one end of the connecting rod assembly. The other end of the connecting rod assembly is shaft-connected to a second rotating shaft, which is eccentrically connected relative to the rotating wheel. The rotating wheel is drively connected to the motor, which is fixed to the mounting plate. When the motor drives the rotating wheel to rotate, the connecting rod assembly, in conjunction with the base plate and the slider, reciprocates relative to the track. One end of the push rod extends into the discharging guide rail and reciprocates along the length of the discharging guide rail. The blocking mechanism includes a bracket, a lifting rod, a swing rod assembly, a top rod, and a top rod seat. The bracket is positioned relative to the track. The mounting plate is fixed, and the lifting rod slides vertically relative to the bracket. In the initial state, one end of the lifting rod extends into the material dropping track near the outlet. A protruding rod protrudes outward from the bracket on one side of the lifting rod. The swing rod assembly includes a horizontal rod and a vertical rod. A swing seat is fixedly connected between the horizontal rod and the vertical rod. The swing seat swings relative to the bracket in a limited position. In the initial state, the horizontal rod abuts against the lower part of the protruding rod. The top rod seat is fixed to the base plate or the push rod. The top rod seat is fixedly connected to the top rod. The end of the top rod abuts against one side of the vertical rod of the swing rod assembly. When the top rod slides back and forth with the push rod or the slider, the end of the top rod abuts against or separates from one side of the vertical rod. When the top rod pushes the vertical rod into place, the swing seat swings relative to the bracket, and the horizontal rod drives the lifting rod to rise into place. When the lifting rod rises into place, it releases the obstruction to the bearing inside the material dropping guide rail. When the top rod separates from the vertical rod into place, the lifting rod returns to its initial state under its own weight, and the protruding rod of the lifting rod pushes the horizontal rod to form the initial state of the swing rod assembly. In the above structure, by linking the material blocking mechanism in the material dropping guide rail with the push rod of the material discharge guide rail, the consistency of their operation is effectively ensured, and the bearing discharge and conveying is relatively stable and reliable.

[0005] When the push rod pushes the bearing in the discharge guide rail, the lifting rod blocks the bearing at the outlet of the discharge guide rail; when the push rod finishes pushing the bearing and moves in the reverse direction, the lifting rod releases its obstruction of the bearing at the outlet of the discharge guide rail, and the bearing falls from the outlet of the discharge guide rail into the discharge guide rail. This structure, as a specific structure of Implementation Scheme One, enables the bearing to be blocked in the discharge guide rail before entering the discharge guide rail, effectively preventing the bearing from being thrown out of the discharge track due to rolling inertia.

[0006] The bottom of the outlet of the discharge guide rail is lower than the top of the side of the discharge guide rail. When the push rod pushes the bearing in the discharge guide rail, the lifting rod blocks the bearing inside the discharge guide rail. When the push rod finishes pushing the bearing and moves in the opposite direction, the lifting rod releases its blockage of the bearing inside the discharge guide rail, and the bearing enters the outlet of the discharge guide rail but is blocked by the top of the side plate of the discharge guide rail. When the push rod separates from the vertical rod of the swing rod assembly, the lifting rod resets under its own weight and pushes the bearing at the outlet of the discharge guide rail past the side plate of the discharge guide rail into the discharge guide rail. This structure, as a specific structure of implementation scheme two, realizes that after the bearing in the discharge guide rail is blocked, the bearing needs to be pushed out from the outlet of the discharge guide rail into the discharge guide rail by the downward pressure when the lifting rod resets. This design makes it easier to grasp the timing of the bearing entering the discharge guide rail from the discharge guide rail and effectively prevents the bearing from interfering with the push rod when entering the discharge guide rail.

[0007] The top of the lifting rod is equipped with a removable counterweight. This structure allows for the selection of appropriate counterweights to meet the force requirements for the lifting rod to reset.

[0008] The vertical rod of the swing arm assembly is magnetically connected to the top rod when they come into contact. This structure eliminates the rigid connection between the vertical rod and the top rod, resulting in a simpler structure and more flexible and reliable linkage. Furthermore, the magnetic attraction provides an effective restoring force to the swing arm assembly when the top rod pulls the vertical rod, ensuring the lifting rod reliably returns to its original position.

[0009] A bolt seat is provided on one side of the push rod seat, which is fixedly connected to the push rod or base plate by bolts. One end of the push rod is threaded and threadedly connected to an anti-rotation nut and the push rod seat. The anti-rotation nut locks the push rod and the push rod seat together. This structure allows for easy adjustment of the push rod position according to the actual linkage requirements of the material blocking mechanism.

[0010] The push rod is adjustablely slidably fixed relative to the base plate. Specifically, the push rod or base plate has a sliding hole, and the push rod and base plate are slidably engaged in the sliding hole via bolts, and then locked in place by nuts. This structure allows for easy adjustment of the push rod's stroke position to accommodate the material blocking operation of the material blocking mechanism.

[0011] The linkage assembly is length-adjustable, comprising a main rod and a secondary rod. One end of the main rod has a second sleeve that movably engages with the second rotating shaft, and the other end has a rotatable sleeve fitted onto it. The sleeve and the main rod are secured together radially with screws. One end of the secondary rod has a first sleeve that engages with the first rotating shaft, and the other end is threadedly connected to the sleeve. This structure allows adjustment of the linkage assembly's length, thereby adjusting the travel position of the base plate relative to the track, meeting the needs of actual linkage.

[0012] The top surface of the rotating wheel has a guide groove along its diameter. A guide block slides within the guide groove, and the guide block integrates the second rotating shaft. The guide block and the guide groove are fixed together by a locking nut connected to the second rotating shaft. This structure facilitates adjustment of the eccentric position of the connection between the rotating wheel and the connecting rod assembly, thereby adjusting the travel of the base plate relative to the track.

[0013] The working method of the bearing conveying and discharging device is as follows: the motor drives the rotating wheel to rotate, and the second rotating shaft eccentrically set on the rotating wheel drives the connecting rod assembly. The connecting rod assembly drives the base plate and the slider to slide back and forth relative to the track. When the base plate drives the push rod to slide into the direction of extending into the discharge guide rail, it forms a pushing operation on the bearing in the discharge guide rail. At the same time as pushing, the base plate or push rod drives the top rod seat, and the top rod seat drives the top rod to link with the swing rod assembly to form a swing rotation. The cross bar of the swing rod assembly drives the convex rod and the lifting rod to form an upward movement. When the push rod completes the pushing and moves in the reverse direction, the lifting rod releases the obstruction of the bearing in the dropping guide rail. The bearing rolls down along the outlet of the dropping guide rail into the discharge guide rail, and the bearing does not contact the push rod during the rolling process.

[0014] The overall structure of this invention is relatively reasonable, realizing the linkage between bearing material blocking and material pushing, thereby ensuring that the conveying of bearings is relatively stable and reliable when switching from one station guide rail to another, and is not prone to derailment and jamming. It is suitable for use as a material discharge device for station switching conveying in various bearing conveying fields, or as a structural improvement of similar devices.

[0018] The present invention will now be further described with reference to the accompanying drawings.

[0019] like Figure 1 , Figure 2 As shown, the bearing conveying and discharging device is located at the junction of the dropping guide rail 1 and the discharging guide rail 2, forming a horizontal 90° angle between them. The discharging device includes a mounting plate 4, a track 5, a slider 6, a base plate 7, a push rod 8, a connecting rod assembly, a rotating wheel 17, a motor 16, and a blocking mechanism. The blocking mechanism includes a bracket 14, a lifting rod 15, a swing rod assembly, a top rod 10, and a top rod seat 9. The connecting rod assembly includes a main rod 19, a secondary rod 20, and a rod sleeve 21. One end of the main rod is fitted with the rod sleeve, and the rod sleeve has radial screw holes. Screws are connected through the screw holes to fix the main rod and the rod sleeve. One end of the secondary rod has an external thread and is threaded to the internal thread of the rod sleeve. The swing rod assembly includes a swing base 11, a horizontal rod 12, and a vertical rod 13, with the horizontal rod and the vertical rod connected to the swing base at a 90° angle. The aforementioned mounting plate, bracket, unloading guide rail, and discharge guide rail are fixed to the same platform bracket, or each is fixed to an independent platform bracket, and their relative positions are fixed.

[0020] The upper end of the mounting plate 4 is fixedly connected to the rail 5 by bolts. The slider 6 is slidably mounted on the rail. The base plate 7 is fixed to the slider by bolts. The push rod 8 is fixed to the base plate by bolts in an adjustable sliding manner. That is, the push rod has a sliding hole that slides with the bolt. The bolt passes through the sliding hole and connects to the base plate. When the bolt is loosened, the push rod adjusts along its length. When the bolt is fixed, the push rod is fixed to the base plate. A vertical first rotating shaft 18 is fixed at one end of the upper end of the base plate. A motor 17 is fixed at the lower end of the mounting plate. The rotating shaft of the motor extends out of the upper end of the mounting plate and drives the rotating wheel 17. The top surface of the rotating wheel has a guide groove 1701 along the diameter direction. A guide block slides in the guide groove. A second rotating shaft 22 parallel to the first rotating shaft is integrated in the guide block. The guide block and the guide groove are fixed by a locking nut connected to the second rotating shaft. The fixed second rotating shaft is eccentrically set relative to the rotating wheel. The first rotating shaft is connected to the first sleeve 2001 at the other end of the auxiliary rod 20 of the connecting rod assembly, and the second sleeve 1901 at the other end of the main rod 19 of the connecting rod assembly is connected to the second rotating shaft. The end of the second rotating shaft after the connection is connected to a washer and a nut to form a limit. When the motor drives the rotating wheel to rotate, the connecting rod assembly linkage base plate and the slider reciprocate relative to the track, and one end of the push rod extends into the discharge guide rail and reciprocates along the length of the discharge guide rail.

[0021] The lifting rod 15 of the aforementioned material-stopping mechanism slides vertically relative to the vertical through hole provided in the bracket 14. Initially, one end of the lifting rod extends into the material drop track 1 near the outlet. A protruding rod 1501 protrudes outward from the bracket on one side of the lifting rod, and a vertical sliding hole 1401 guides the protruding rod to slide vertically on the side of the bracket. The swing seat 11 of the swing rod assembly swings relative to the bracket via a swing shaft. Initially, the horizontal bar 12 of the swing assembly abuts against the lower part of the protruding rod. A bolt seat is provided on one side of the top rod seat 9, which is fixedly connected to the push rod by bolts, or as... Figure 1 As shown, the push rod is connected and fixed together with the bolts of the base. One end of the push rod 10 is threaded and threadedly connected to the anti-rotation nut and the push rod seat. Through this threaded connection, the position of the push rod relative to the push rod seat is adjusted, and the anti-rotation nut locks the push rod and the push rod seat together to prevent rotation. The end of the push rod abuts against one side of the vertical rod 13 of the swing rod assembly. When the push rod slides back and forth with the push rod 8 or the slider 6, the end of the push rod abuts against or separates from one side of the vertical rod. When the push rod pushes the vertical rod into place, the swing seat swings relative to the bracket, and the crossbar drives the lifting rod to rise into place. When the lifting rod rises into place, it releases the obstruction of the bearing 3 inside the dropping guide rail 1. When the push rod separates from the vertical rod into place, the lifting rod returns to its initial state under its own weight, and the protrusion of the lifting rod pushes the crossbar to the swing rod assembly to form the initial state. The specific implementation linkage state is as follows: when the push rod pushes the bearing in the discharge guide rail, the lifting rod is in a blocking state against the bearing at the outlet of the discharge guide rail; when the push rod finishes pushing the bearing and moves in the reverse direction, the lifting rod releases its obstruction of the bearing at the outlet of the discharge guide rail, and the bearing falls from the outlet of the discharge guide rail into the discharge guide rail.

[0022] Furthermore, the bottom of the outlet of the aforementioned material drop guide 1 can also be designed to be lower than the top of the side of the discharge guide 2, so that the above-mentioned linkage state becomes: when the push rod 8 pushes the bearing 3 in the discharge guide, the lifting rod 15 is in a blocking state against the bearing in the material drop guide; when the push rod finishes pushing the bearing and moves in the opposite direction, the lifting rod releases the obstruction of the bearing in the material drop guide, and the bearing enters the outlet of the material drop guide and is blocked by the top of the side plate of the discharge guide; when the push rod 10 separates from the vertical rod 13 of the swing rod assembly, the lifting rod resets under its own weight and squeezes the bearing at the outlet of the material drop guide past the side plate of the discharge guide and into the discharge guide.

[0023] Furthermore, the top of the aforementioned lifting rod 15 is threaded or plugged into a counterweight 1502. The appropriate counterweight can be selected as needed to meet the force requirements for the lifting rod to reset.

[0024] Furthermore, when the bottom of the vertical rod 13 of the aforementioned rocker arm assembly contacts the top rod 10, the connection is magnetic. That is, magnets are installed at the end of the top rod and the bottom of the vertical rod, attracting each other when they are close together and releasing the magnetic attraction when they move away from each other or disconnect. Through this structure, there is no rigid connection between the top rod and the vertical rod, and the top rod pulling the vertical rod helps the rocker arm assembly to reset.

[0025] The working method of the bearing conveying and discharging device is as follows: First, according to the discharging and conveying requirements of the bearing 3 in the discharging guide rail 2, for example, the push rod 8 is set to push the bearing in the discharging guide rail by a bearing spacing for each reciprocating stroke. The stroke position adjustment of the push rod includes adjusting the position of the push rod relative to the base plate 7, adjusting the eccentric position of the second rotating shaft 22 on the rotating wheel 17, and adjusting the length of the connecting rod assembly. All of the above adjust the stroke position of the push rod to meet the requirements of pushing the bearing in the discharging guide rail. At the same time, according to the bearing dropping state of the dropping guide rail 1, the working state of the blocking mechanism is adjusted. Specifically, the position of the top rod 10 relative to the top rod seat 9 is adjusted, thereby adjusting the position of the top rod pushing the swing rod assembly to lift the lifting rod 15, that is, releasing the obstruction state of the bearing in the dropping guide rail, so that when the bearing in the dropping guide rail falls into the discharging guide rail, it avoids interference with the push rod. The specific working state is as follows: the motor 16 drives the rotating wheel to rotate, and the second rotating shaft 22 eccentrically set on the rotating wheel drives the connecting rod assembly. The connecting rod assembly drives the base plate and the slider 6 to slide back and forth relative to the track 5. When the base plate drives the push rod to slide into the discharge guide rail, it forms a pushing operation on the bearing in the discharge guide rail. At the same time as pushing, the push rod drives the top rod seat, and the top rod seat drives the top rod to swing the swing rod assembly. The horizontal bar of the swing rod assembly drives the convex rod 1501 and the lifting rod to rise. When the push rod completes the pushing and moves in the reverse direction, the lifting rod releases the obstruction of the bearing in the discharge guide rail. The bearing rolls down along the outlet of the discharge guide rail into the discharge guide rail. During the time period when the bearing rolls down, the push rod moves in the reverse direction until there is no interference with the bearing, thus completing one bearing station change and conveying.

[0026] The above description is intended to illustrate the technical means of the present invention and is not intended to limit the scope of the invention. Any obvious improvements or substitutions made to the present invention by those skilled in the art based on existing common knowledge also fall within the protection scope of the claims of the present invention.
