Description

Technical Field

[0001] This utility model relates to the field of bearing packaging equipment technology, specifically to a tapered roller feeding structure. Background Technology

[0002] The core advantage of tapered roller bearings lies in their excellent load-bearing capacity. They can withstand huge combined radial and axial loads simultaneously, and their rigid design limits the axial displacement of the shaft and housing, ensuring high rotational accuracy. Thanks to the structure of tapered rollers, they are easy to install and adjust clearance, and are usually used in pairs to optimize performance. Therefore, they are particularly suitable for critical parts in automobiles, machine tools, mining machinery, and other applications requiring high load and high rigidity.

[0003] Vibratory feeders are commonly used in the industry as the core feeding mechanism. Vibratory feeders use the principle of electromagnetic vibration to orient and sort the disordered roller parts and output them in an orderly manner along a preset track. In order to control the rollers to enter the subsequent packaging process in a specific and uniform posture (usually with their central axis parallel to the conveying direction), specific limiting structures, such as guide grooves or limit baffles, are usually set at the output end of the vibratory feeder to screen and correct the output angle of the rollers.

[0004] However, the existing conveying and limiting method has obvious technical defects in practical applications. Due to the conical structure and unique center of gravity distribution of the conical rollers, their motion is uncertain during the high-frequency vibration conveying process of the vibratory feeder. Although a limiting structure is set at the outlet, individual rollers may still accidentally flip or tilt during passage, causing their discharge angle (i.e., the angle between the roller axis and the conveying direction) to deviate from the preset ideal state. These incorrectly angled rollers will be mixed in with the correctly arranged roller flow and enter the packaging stage together. Utility Model Content

[0005] To address the technical problems existing in the background art, this utility model proposes a conical roller feeding structure.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A tapered roller feeding structure includes a mounting bracket, a feeding plate mounted on the mounting bracket, and a drive unit for driving the feeding plate to rotate. The feeding plate has a plurality of transfer grooves for inserting tapered rollers, and a feed pipe for feeding tapered rollers is provided above the feeding plate. A discharge pipe for discharging tapered rollers is provided below the feeding plate. A limit plate is provided on the outer periphery of the feeding plate along the path from the feed pipe to the discharge pipe to prevent the tapered rollers from leaving the transfer grooves. The mounting bracket is provided with a sensor assembly, which has a first sensing part and a second sensing part. The tapered roller has a first orientation and a second orientation. When the tapered roller is placed into the transfer groove in the first orientation, the first sensing part illuminates the tapered roller. When the tapered roller is placed into the transfer groove in the second orientation, part of the tapered roller is exposed in the transfer groove, and the second sensing part illuminates the tapered roller.

[0007] Preferably, the sensor assembly includes an adjustment bracket and a first sensor and a second sensor mounted on the mounting bracket. The feeding tray forms a detection groove for exposed tapered rollers. The first sensor faces the detection groove, and the second sensor faces outward from the feeding tray. With the above improvement, because the tapered roller has an overall shape that is smaller at the bottom and larger at the top, when the tapered roller is placed into the transfer groove in the second posture, it cannot be fully inserted into the transfer groove, allowing the second sensor to illuminate the tapered roller. As a result, the second sensor will send an NG signal. Only when the tapered roller is fully inserted into the transfer groove in the first posture will the first sensor illuminate the tapered roller through the detection groove, thereby sending a qualified signal. This will cause the feeding tray to continue rotating to receive the next tapered roller, allowing the tapered roller to be transported in the specified posture.

[0008] Preferably, the mounting bracket is provided with an adjustment bracket, and the adjustment bracket is provided with an adjustment groove. The first sensor and the second sensor are disposed on the adjustment groove, and the adjustment groove is oriented towards the detection groove. Through the above improvement, the position of the first sensor and the second sensor can be quickly adjusted through the adjustment groove, ensuring the accuracy of the first sensor and the second sensor in sensing the tapered roller.

[0009] Preferably, the feeding tray includes a receiving plate and fixed plates disposed on both sides of the receiving plate. The receiving plate has a plurality of transfer grooves arranged at intervals along the circumference. The detection groove is formed on the fixed plate and is disposed opposite to the transfer grooves. With the above improvement, the tapered rollers are transported from the feed pipe to the transfer grooves on the receiving plate by a vibrating plate or a hopper. The fixed plates limit the tapered rollers, and as the entire feeding tray rotates, the tapered rollers on the transfer grooves fall into the discharge pipe for discharge, so that the tapered rollers are transported in a specified posture.

[0010] Preferably, the mounting bracket is provided with a rejection component opposite to the rotation direction of the feeding tray. The rejection component includes a clamping unit for clamping the tapered roller and a drive module for driving the clamping unit to move. With the above improvement, when a non-compliant feeding occurs, the feeding tray will rotate counterclockwise, causing the tapered roller in the second posture to move toward the rejection component. The drive module will drive the clamping unit to approach and clamp the tapered roller, causing it to leave the transfer groove, thus realizing the unloading of the non-compliant tapered roller.

[0011] Preferably, a recycling tray is provided below the rejection component. With the above improvements, when the clamping unit releases the tapered roller, the tapered roller falls into the recycling tray, thereby realizing the recycling of the tapered roller.

[0012] Preferably, the insertion end of the transfer groove is provided with an arc-shaped guide surface. Through the above improvements, the smoothness of the tapered roller during the feeding process is greatly increased.

[0013] Preferably, the discharge pipe has a feeding notch, and the limiting plate is disposed on the feeding notch. Through the above improvements, the smoothness of the conical roller discharge is increased.

[0014] Preferably, a counting sensor is inserted into the discharge pipe, and through the above improvements, the number of tapered rollers output can be accurately calculated.

[0015] Preferably, the limiting plate is arc-shaped and fits against the outer periphery of the feeding tray. Through the above improvements, the smoothness of the feeding tray during rotation is increased, and the conical rollers are prevented from falling out of the transfer groove during the rotation of the feeding tray.

[0016] Compared with the prior art, the present invention has the following advantages and beneficial effects: Material is received through a feed pipe, and the tapered roller falls into the transfer groove of the loading tray. A sensor assembly is mounted on the mounting bracket, comprising a first sensing part and a second sensing part. The tapered roller has an overall shape that is smaller at the bottom and larger at the top, and it has a first orientation and a second orientation. When the tapered roller is placed into the transfer groove in the first orientation, the first sensing part illuminates the roller. This prevents the roller from being fully inserted into the transfer groove when placed in the second orientation, allowing the second sensor to illuminate the roller. The tapered roller is fully inserted into the transfer trough in the first orientation. The first sensor then sends an NG signal when the tapered roller is fully inserted in the first orientation. The first sensor then sends a qualified signal when the tapered roller is illuminated by the detection slot. This causes the feeding tray to continue rotating to receive the next tapered roller, ensuring that the tapered roller is conveyed in the specified orientation. This achieves automatic identification of the tapered roller's orientation. The entire identification and sorting process requires no manual intervention and can be perfectly matched with the production line rhythm, significantly improving feeding and packaging efficiency while reducing labor costs and labor intensity.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0020] like Figure 1-6 As shown, a tapered roller feeding structure includes a mounting bracket 1, a feeding plate 2 mounted on the mounting bracket 1, and a drive unit 3 for driving the feeding plate 2 to rotate. The feeding plate 2 has a plurality of transfer grooves 4 for inserting tapered rollers, and a feed pipe 5 for feeding tapered rollers is provided above the feeding plate 2. A discharge pipe 6 for discharging tapered rollers is provided below the feeding plate 2. A limit plate 7 is provided on the path from the feed pipe 5 to the discharge pipe 6 on the outer periphery of the feeding plate 2 to prevent the tapered rollers from leaving the transfer grooves 4.

[0021] Specifically, a sensor assembly 8 is provided on the mounting bracket 1. The sensor assembly 8 has a first sensing part and a second sensing part. The tapered roller has a first orientation and a second orientation. When the tapered roller is placed into the transfer groove 4 in the first orientation, the first sensing part irradiates the tapered roller. When the tapered roller is placed into the transfer groove 4 in the second orientation, part of the tapered roller is exposed in the transfer groove 4, and the second sensing part irradiates the tapered roller.

[0022] During the entire tapered roller unloading process, the finished tapered rollers fall into the transfer groove 4 of the loading tray 2 through the feed pipe 5. Because the tapered rollers are shaped with a smaller bottom and a larger top, they have a first orientation and a second orientation. Due to this orientation, when the tapered rollers are placed in the transfer groove 4 in the second orientation, they cannot be fully inserted. Furthermore, the mounting bracket 1 is equipped with a sensor assembly 8, which has a first sensing part and a second sensing part. When the tapered rollers are placed in the transfer groove 4 in the first orientation, the first sensing part illuminates the tapered rollers, and when they are placed in the transfer groove 4 in the second orientation... When the tapered roller is partially exposed in the transfer groove 4, and the second sensor irradiates the tapered roller, the second sensor 1.3 will send an NG signal and reject the NG tapered roller. Only when the tapered roller is fully placed in the transfer groove 4 in the first posture, the first sensor 1.2 will irradiate the tapered roller through the detection groove and send a qualified signal, causing the feeding tray 2 to continue rotating to receive the next tapered roller, so that the tapered roller is conveyed in the specified posture, thereby realizing the automatic recognition of the tapered roller posture. The entire recognition and sorting process does not require manual intervention, can be perfectly matched with the production line rhythm, greatly improves the feeding and packaging efficiency, and reduces labor costs and labor intensity.

[0023] like Figure 1-6 As shown, as a further explanation of the implementation of the sensor assembly 8 in this embodiment, the sensor assembly 8 includes an adjustment bracket 1.1, and a first sensor 1.2 and a second sensor 1.3 disposed on the mounting bracket 1. The feeding tray 2 forms a detection groove for exposing the tapered roller. The first sensor 1.2 is disposed facing the detection groove, and the second sensor 1.3 is disposed facing the outside of the feeding tray 2.

[0024] Because the tapered roller has a bottom-to-top shape, when it is placed into the transfer groove 4 in the second orientation, it cannot be fully inserted into the groove 4. This allows the second sensor 1.3 to illuminate the tapered roller, causing it to send an NG signal. Only when the tapered roller is fully inserted into the transfer groove 4 in the first orientation will the first sensor 1.2 illuminate the tapered roller through the detection groove 1.5, causing it to send a qualified signal. This allows the feeding tray 2 to continue rotating to receive the next tapered roller, ensuring that the tapered roller is transported in the specified orientation.

[0025] Furthermore, the mounting bracket 1 is provided with an adjusting bracket 1.4, and the adjusting bracket 1.1 is provided with an adjusting groove 1.4. The first sensor 1.2 and the second sensor 1.3 are disposed on the adjusting groove 1.4, and the adjusting groove 1.4 is oriented towards the detection groove 1.5. The position of the first sensor 1.2 and the second sensor 1.3 can be quickly adjusted through the adjusting groove 1.4 to ensure the accuracy of the first sensor 1.2 and the second sensor 1.3 in sensing the tapered roller.

[0026] Preferably, a counting sensor 1.6 is inserted into the discharge pipe 6, which can accurately calculate the number of tapered rollers output.

[0027] like Figure 1-2 As shown, as a further explanation of the implementation method for unloading NG tapered rollers, a rejection component 3.1 is provided on the mounting bracket 1 opposite to the rotation direction of the feeding tray 2. The rejection component 3.1 includes a clamping unit 3.2 for clamping the tapered rollers and a drive module 3.3 for driving the clamping unit 3.2 to move. When an NG situation occurs during feeding, the rejection component 3.1 will receive an NG signal, and the feeding tray 2 will rotate counterclockwise, causing the tapered rollers in the second posture to move toward the rejection component 3.1. The drive module 3.3 will drive the clamping unit to approach and clamp the tapered rollers, causing them to disengage from the transfer groove 4, thereby realizing the unloading of NG tapered rollers.

[0028] Furthermore, a recycling tray 3.4 is provided below the rejection component 3.1. When the clamping unit releases the tapered roller, the tapered roller falls into the recycling tray 3.4, thereby realizing the recycling of the tapered roller.

[0029] like Figure 1-6 As shown, a further explanation of the embodiment of the feeding tray 2 is provided. The feeding tray 2 includes a receiving plate 2.1 and fixing plates 2.2 disposed on both sides of the receiving plate 2.1. The receiving plate 2.1 has a plurality of transfer grooves 4, which are arranged at intervals along the circumference. The detection groove is formed on the fixing plate 2.2 and is disposed opposite to the transfer grooves 4. The conical rollers are transported from the feed pipe 5 to the transfer grooves 4 on the receiving plate 2.1 by a vibrating plate or hopper. The fixing plates 2.2 limit the conical rollers. As the entire feeding tray 2 rotates, the conical rollers on the transfer grooves 4 fall into the discharge pipe 6 for discharge, so that the conical rollers are transported in a specified posture.

[0030] Preferably, the insertion end of the transfer groove 4 is provided with an arc-shaped guide surface 4.1, which greatly increases the smoothness of the tapered roller during the feeding process.

[0031] Preferably, the discharge pipe 6 has a feed notch 4.2, and the limiting plate 7 is set on the feed notch 4.2 to increase the smoothness of the tapered roller discharge.

[0032] Preferably, the limiting plate 7 is arc-shaped and fits against the outer periphery of the feeding plate 2, which increases the smoothness of the feeding plate 2 during rotation and prevents the conical rollers from falling out of the transfer groove 4 during the rotation of the feeding plate 2.

[0033] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
