Description

Technical Field

[0001] This invention relates to a tapered roller directional conveying device, belonging to the technical field of bearing parts production equipment. Background Technology

[0002] Tapered rollers are rolling elements in tapered roller bearings and are a crucial component. During the production of tapered rollers, grinding is required. Conventional raceway grinding and feeding equipment requires the smaller end of the tapered roller to enter the grinding equipment first, followed by the larger end, to prevent the larger end from entering first and causing jamming of the guide plates and guide wheels within the grinding equipment, leading to equipment damage. To address this deficiency, our company developed a device for controlling the direction of the larger and smaller ends of tapered rollers (Authorization Announcement No.: CN208811849U; Name: Tapered Roller Larger and Smaller End Control Device and Material Transfer Mechanism; Authorization Announcement Date: May 3, 2019). This device utilizes two counter-rotating rollers and the gravity characteristics of the tapered rollers themselves to automatically and continuously control the direction of the larger and smaller ends. However, it still has the following shortcomings: 1. The transition connection structure between the lower end of the roller and the feeding bend is rough. Although a retaining groove is installed above the feeding bend... However, its guiding effect on tapered rollers is limited. Especially when the tapered rollers are disengaging from the rollers or have just disengaged from the rollers, the tapered rollers are very prone to swinging towards the rollers due to the collision between the side wall and the lower end of the rollers. This can easily cause the lower end of the tapered rollers to extend beyond the upper end of the feed bend, thus blocking the feed bend. 2. The rollers do not have a pushing structure on their surface. The conveying of the tapered rollers is achieved solely by the weight of the tapered rollers themselves and the friction between the tapered rollers and the rollers. This results in the defects of difficulty in controlling the roller conveying rhythm and low conveying efficiency. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned technical deficiencies of existing tapered roller head-to-tail orientation control equipment by providing a new tapered roller orientation conveying device. This device features spiral groove structures on the two rollers of the orientation roller assembly, enabling active and rhythmically controllable conveying of the tapered rollers. Furthermore, a guiding structure is creatively incorporated on the outer side of the material discharge end of the orientation roller assembly. This guiding structure employs a linked swing stop and swing guide plate, providing precise and stable guidance for the tapered rollers just disengaged from the orientation roller assembly. This effectively ensures that the tapered rollers reliably enter the material discharge bend with the smaller end in front and the larger end behind, thus achieving precise and reliable orientation control of the tapered roller heads.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0005] A tapered roller orientation conveying device includes a frame and an orientation roller assembly and a feeding bend mounted on the frame. The orientation roller assembly includes a first rotating roller and a second rotating roller that are parallel to each other. The gap between the first rotating roller and the second rotating roller is larger than the small end of the tapered roller and smaller than the large end of the tapered roller.

[0006] The first and second rollers are provided with spiral grooves on their circumferential surfaces. When the first and second rollers rotate in opposite directions with their adjacent sides facing upwards, the spiral grooves on the circumferential surfaces of the first and second rollers will push the conical rollers to move downwards to the material end.

[0007] The upper end of the feeding bend is located below the outer side of the feeding end of the directional roller assembly. The upper end of the feeding bend is equipped with a U-shaped stop that opens towards the gap between the first and second rollers. The connecting part of the two wings of the U-shaped stop is located directly in front of the outer side of the feeding end of the directional roller assembly. Swinging stops are freely mounted on the two wings of the U-shaped stop. A swing guide plate is rotatably mounted on the edge of the upper end of the feeding bend on the opening side of the U-shaped stop. Connecting parts are provided between the two sides of the swinging stop and the two sides of the swing guide plate. The connecting parts and the swinging stops... All the swing guide plates are hinged. When the swing stop is in a free vertical state, the swing stop makes the swing guide plate flip outward through the connector. At this time, the swing guide plate is located below the directional roller group and there is enough space between it and the directional roller group to allow the tapered roller to pass through. When the swing stop is squeezed by the tapered roller and swings outward, the swing stop lifts the swing guide plate through the connector. During the process of the swing guide plate flipping forward and standing up, the small end of the tapered roller will be pushed to the upper port of the lower material bend.

[0008] By adopting the above technical solution, a tapered roller directional conveying device is provided. This device features spiral groove structures on the two rollers of the directional roller assembly, enabling active and rhythmically controllable conveying of the tapered rollers. Furthermore, a guiding structure is creatively installed on the outer side of the material discharge end of the directional roller assembly. This guiding structure employs a linked swing stop and swing guide plate, which precisely and stably guides the tapered rollers that have just detached from the directional roller assembly. This effectively ensures that the tapered rollers reliably enter the material discharge bend with the smaller end in front and the larger end behind, achieving precise and reliable directional control of the tapered rollers' large and small ends.

[0009] A further feature of the present invention is that the swing stop is mounted on the two wings of the U-shaped stop using a combination of a crossbeam and a triangular support.

[0010] A further feature of the present invention is that the connecting member is located between the swing stop and the triangular support.

[0011] By adopting the above technical solution, the specific placement method of the connector is defined.

[0012] A further feature of the present invention is that the swing stop has a plate-like structure, and a shock-absorbing layer is provided on the side of the swing stop near the directional roller assembly.

[0013] A further feature of the present invention is that the upper surface of the swing guide plate is also provided with a shock-absorbing layer.

[0014] By adopting the above technical solution, a shock-absorbing layer is provided on the surfaces of the swing stop and swing guide plate that come into contact with the tapered rollers, which can effectively prevent damage to the tapered rollers or transfer components caused by hard contact.

[0015] A further configuration of the present invention is that the first roller and the second roller are rotatably mounted within a rectangular enclosure with an opening at the top via a rotating shaft at their respective feeding ends.

[0016] A further feature of the present invention is that the swing stop is freely swingable and mounted on the left and right side panels of the rectangular enclosure.

[0017] By adopting the above technical solution, the first and second rotating rollers are placed inside the rectangular enclosure, which can effectively ensure the safety of use and the cleanliness and hygiene of the rotating rollers themselves. In addition, the swing stop can also be directly placed on the left and right side plates of the rectangular enclosure, providing more installation methods.

[0018] A further feature of the present invention is that a nylon sleeve is fixedly fitted on the circumferential surface of the first roller and the second roller, and a spiral groove is provided on the outer circumferential surface of the nylon sleeve.

[0019] A further configuration of the present invention is that the first roller and the second roller are arranged obliquely with the upper end higher than the lower end.

[0020] By adopting the above technical solution, a nylon sleeve is fitted on the outer surface of the roller. The hardness of the nylon sleeve allows the roller to have a certain elastic deformation capability, making it less likely to damage the tapered roller.

[0021] The main beneficial effects of this invention are:

[0022] 1. The conical roller directional conveying device of the present invention has a spiral groove structure correspondingly set on the two directional rollers, which can realize active and rhythmically controllable conveying of the conical rollers. At the same time, a guide structure is creatively set on the outside of the feeding end of the directional roller group. The guide structure adopts a linked swing stop and swing guide plate, which can accurately and stably guide the conical rollers that have just left the directional roller group. It can effectively ensure that the conical rollers that have left the directional roller group can enter the feeding bend in a stable and reliable manner with the small end in front and the large end behind, and accurately and reliably realize the directional control of the large and small ends of the conical rollers.

[0023] 2. The tapered roller directional conveying device of the present invention is provided with a shock-absorbing layer on the surfaces of the swing stop and the swing guide plate that will contact the tapered roller, which can effectively avoid damage to the tapered roller or the transfer component caused by hard contact.

[0024] 3. The conical roller directional conveying device of the present invention places the first and second rollers inside a rectangular enclosure, which can effectively ensure the safety of use and the cleanliness of the rollers themselves. In addition, based on this, the swing stop can also be directly placed on the left and right side plates of the rectangular enclosure, providing more installation methods.

[0025] 4. The tapered roller orientation conveying device of the present invention has a nylon sleeve on the outer surface of the roller. The hardness of the nylon sleeve allows the roller to have a certain elastic deformation capability, making it less likely to damage the tapered roller. Attached Figure Description

Detailed Implementation

[0035] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] Example 1:

[0037] like Figures 1 to 7 As shown, a tapered roller directional conveying device includes a frame 1 and a directional roller assembly and a feeding bend 3 mounted on the frame 1. The directional roller assembly includes a first roller 4 and a second roller 5 that are parallel to each other. The gap between the first roller 4 and the second roller 5 is larger than the small end of the tapered roller 8 and smaller than the large end of the tapered roller 8. Nylon sleeves are fixedly fitted on the circumferential surfaces of the first roller 4 and the second roller 5, and spiral grooves 6 are provided on the outer circumferential surface of the nylon sleeves. The first roller 4 and the second roller 5 are arranged obliquely with the feeding end higher than the feeding end.

[0038] The first roller 4 and the second roller 5 are provided with spiral grooves 6 on their circumferential surfaces. When the first roller 4 and the second roller 5 rotate in opposite directions with their adjacent sides facing upwards, the spiral grooves 6 on the circumferential surfaces of the first roller 4 and the second roller 5 will push the conical roller 8 to move downwards to the material end.

[0039] The upper end of the feeding bend 3 is located below the outer side of the feeding end of the directional roller assembly. The upper end of the feeding bend 3 is provided with a U-shaped stop 9 with its opening facing the gap between the first roller 4 and the second roller 5. The connecting part 91 of the two wings 92 of the U-shaped stop 9 is located directly in front of the outer side of the feeding end of the directional roller assembly. The two wings 92 of the U-shaped stop 9 are equipped with swinging stops 12 that can swing freely, using a combination of a crossbeam 11 and a triangular bracket 10. A swinging guide plate 13 is rotatably mounted on the edge of the upper end of the feeding bend 3 on the opening side of the U-shaped stop 9. Connectors 14 are provided between the two sides of the swing stop 12 and the two sides of the swing guide plate 13. The connectors 14 are hinged to both the swing stop 12 and the swing guide plate 13. The connectors 14 are located between the swing stop 12 and the triangular bracket 10. When the swing stop 12 is in a free vertical state, the swing stop 12 causes the swing guide plate 13 to be in an outward-folded state through the connectors 14. At this time, the swing guide plate 13 is located below the directional roller group and there is enough space between it and the directional roller group to allow the tapered roller 8 to pass through. The swing stop 12 has a plate-like structure. A damping layer is provided on the side of the swing stop 12 closest to the directional roller group. A damping layer is also provided on the upper surface of the swing guide plate 13.

[0040] Example 2:

[0041] The difference between Embodiment 2 and Embodiment 1 is that the first roller 4 and the second roller 5 are rotatably mounted in the rectangular enclosure 2 with the top opening via the rotating shaft 7 at their feeding ends, and the swing stop 12 is freely mounted on the left and right side plates of the rectangular enclosure 2.

[0042] In use, the tapered roller 8 is placed at the feed end of the directional roller assembly. Under the action of gravity, the larger end of the tapered roller 8 is stuck between the first roller 4 and the second roller 5, while the smaller end falls to the lower side of the gap between the first roller 4 and the second roller 5. The first roller 4 and the second roller 5 rotate in opposite directions with their adjacent sides facing upwards. The spiral grooves 6 on the first roller 4 and the second roller 5 push the tapered roller 8 to move towards the lower feed end. When the swing stop 12 is squeezed outwards by the tapered roller 8, the swing stop 12 lifts the swing guide plate 13 through the connector 14. During the process of the swing guide plate 13 flipping forward and standing up, it pushes the smaller end of the tapered roller 8 towards the upper port of the lower feed bend 3, perfectly realizing the directional falling of the tapered roller 8.
