Description

Technical Field

[0001] The present invention relates to the technical field of metallurgy, and particularly relates to an automatic collecting device for waste bearings. Background Art

[0002] In the steel industry, in the production line of the bar and wire mill, an important tooling part during the rolling of the finishing mill is the rolling guide guard. The guide rollers in the rolling guide guard need to be replaced regularly. When replacing the guide rollers each time, the bearings in the guide rollers need to be disassembled for replacement and inspection. The waste bearings after inspection need to be recycled. Currently, the recycling method of bearings in the workshop is to directly throw them into the waste bin, which easily leads to the mixing of bearings and other sundries. It is not only difficult to clean but also likely to cause certain cost losses. Although there are currently people who collect waste bearings in a standardized manner manually, that is, multiple waste bearings are threaded together with iron wire for collection (as Figure 12 shown), and then uniformly recycled, but the manual processing method can only be applied to the collection of a small number of waste bearings. When dealing with a large number of waste bearings for recycling, the manual labor intensity is relatively high, and the standardized collection efficiency is relatively low.

[0037] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0038] Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification. Embodiment

[0039] Such as Figure 1-11As shown in the figure, the present invention provides an automatic collection device for waste bearings, including a support table 1, on which a indexing plate device 2 is fixedly installed. Along the circumferential direction of the indexing plate of the indexing plate device 2, three collecting cylinders 3 penetrating through the indexing plate are equidistantly distributed. The three collecting cylinders 3 are all used for collecting waste bearings, and are successively the first station, the second station and the third station in the counterclockwise direction. A stepped hole 4 is formed through the top of the collecting cylinder 3, a bent port 5 communicating with the stepped hole 4 is formed on the outer wall of the collecting cylinder 3, and a lifting port 6 communicating with the stepped hole 4 is formed at the bottom of the collecting cylinder 3. On one side of the support table 1, a vibrating disk body 7 for conveying waste bearings is provided. At the output port of the vibrating disk body 7, a displacement and blanking mechanism 8 is provided. The displacement and blanking mechanism 8 is used to convey the waste bearings in the vibrating disk body 7 into the collecting cylinder 3 at the first station. On the top of the support table 1, a wire conveying mechanism 9 for conveying cut wires and a robotic arm 10 for clamping cut wires and grouped waste bearings are fixedly installed. A jaw is installed at the front end of the robotic arm 10, and the jaw is used to clamp the cut wires. A upper bending mechanism 11 and a lower bending mechanism 12 are arranged on the support table 1. The upper bending mechanism 11 and the lower bending mechanism 12 are corresponding up and down, and are located at the top and bottom of the collecting cylinder 3 at the second station. The upper bending mechanism 11 and the lower bending mechanism 12 are used to bend the top and bottom of the wires placed in the collecting cylinder 3. A lifting mechanism 13 is fixedly installed on the support table 1. The lifting mechanism 13 is arranged below the collecting cylinder 3 at the third station and is used to lift the grouped waste bearings inside the collecting cylinder 3 at the third station. A turnover box 14 for placing grouped waste bearings is arranged on one side of the indexing plate device 2.

[0040] Specifically, after the displacement and blanking mechanism 8 pushes a certain number of waste bearings, it can stop briefly. During this period, the indexing plate device 2 can control the indexing plate to rotate, so that the full collecting cylinder 3 can rotate, and the empty collecting cylinder 3 can be moved below the displacement and blanking mechanism 8 for feeding. And the control system of this method is a well-known and publicly available technology, which is already well-known and can be implemented by those skilled in the art. Since this solution only protects the physical structure and does not involve the protection of circuits and systems, the circuits and systems will not be described in detail. It should be emphasized that the description of the circuits and systems is only a supplementary explanation of the feasibility and authenticity of this solution.

[0041] Combined with Figure 3 and Figure 6As shown in the figure, in this embodiment, the shifting and blanking mechanism 8 includes a support frame 81, a conveying device 82 installed on the support frame 81, a mounting frame 83, a rodless cylinder 84 installed on the mounting frame 83, a pushing frame 85 connected to the rodless cylinder 84, and a guiding member 86 installed on the mounting frame 83. A guiding hole 87 is penetrated through the guiding member 86. The guiding hole 87 corresponds to the stepped hole 4 of the collecting cylinder 3 at the first station. The pushing frame 85 is arranged at one end of the conveying device 82 and is used to push the waste bearings on the conveying device 82 to the top end of the guiding hole 87.

[0042] Specifically, the top of the pushing frame 85 is an L-shaped plate, and a circular groove for fitting the bearing is opened on the outer side of the corner of the L-shaped plate. In this way, when the rodless cylinder 84 works to drive the pushing frame 85 to move, the pushing frame 85 can push the bearing in the circular groove onto the guiding member 86, and the waste bearing can fall from the top end of the guiding hole 87 into the collecting cylinder 3. When the rodless cylinder 84 drives the pushing frame 85 to move, its speed is relatively fast, and the reciprocating work of the pushing frame 85 can be realized quickly, which is beneficial for the waste bearing to enter the guiding hole 87, and there will be no problem of slow movement resulting in the bearing tilting and falling at the guiding hole 87. At the same time, a baffle is provided at the circular groove to further prevent the bearing from tilting at the guiding hole 87.

[0043] More specifically, when the pushing frame 85 is pushed to move the waste bearing, it has a longer side to block the bearing on the conveying device 82 to prevent the bearing from falling. And there is a certain distance between the bottom surface of the guiding member 86 and the top surface of the collecting cylinder 3 to prevent the collecting cylinder 3 from colliding with the shifting and blanking mechanism 8 when it rotates.

[0044] Combined Figure 4 and Figure 8 As shown in the figure, in this embodiment, the upper bending mechanism 11 includes a hanging frame 110 installed on the support table 1, a first cylinder 111 installed on the hanging frame 110, a first sliding seat 112 connected to the output end of the first cylinder 111, a first micro-cylinder 113 movably installed on the first sliding seat 112, an upper pressing seat 114 fixedly installed on the first sliding seat 112, and an upper bending plate 115 hinged to the upper pressing seat 114. Upper bending grooves 15 for bending the iron wire are respectively arranged at the bottoms of the upper pressing seat 114 and the upper bending plate 115 and on one side of the upper bending plate 115, and the output end of the first micro-cylinder 113 is movably connected to the upper bending plate 115.

[0045] Specifically, the bottom surface height of the hanger 110 is higher than the top surface height of the collection cylinder 3. Thus, when the indexing plate device 2 drives the collection cylinder 3 to rotate, there will be no problem of collision between the collection cylinder 3 and the upper bending mechanism 11. Moreover, a transverse guide rail is installed on the hanger 110, and the first sliding seat 112 is slidably connected to the transverse guide rail to ensure the stability of the first sliding seat 112, further ensuring the stability of the upper pressing seat 114 and the upper bending plate 115, which is conducive to the upper bending mechanism 11 bending the iron wire.

[0046] Preferably, an upper notch 16 is formed on the top side of the collection cylinder 3. The upper notch 16 corresponds to the bending notch 5 and the upper bending plate 115 respectively, and the inside of the upper notch 16 is adapted to the bottom end of the upper pressing seat 114 and the outside of the upper bending plate 115.

[0047] Specifically, the inner spacing value of the upper notch 16 is equal to the inner spacing value of the bending notch 5. When a certain amount of waste bearings are collected and placed, the top surface of the topmost bearing is lower than the inner bottom surface of the upper notch 16 and is almost close to the inner bottom surface of the upper notch 16. Thus, when the first cylinder 111 pushes the first sliding seat 112 forward, the upper bending plate 115 and the upper pressing seat 114 move on the top of the topmost bearing, and the spacing distance is greater than and close to the diameter of the iron wire, which is conducive to comprehensively bending the iron wire and ensuring the stability of the bearing group after the iron wire is bent.

[0048] Combined Figure 5 and Figure 9 As shown in the figure, in this embodiment, the lower bending mechanism 12 includes a heightening plate 120 installed on the top of the support table 1, a second cylinder 121 installed on the heightening plate 120, a second sliding seat 122 connected to the output end of the second cylinder 121, a second micro cylinder 123 movably installed on the second sliding seat 122, a lower pressing seat 124 fixedly installed on the second sliding seat 122, and a lower bending plate 125 hinged to the lower pressing seat 124. Lower bending grooves 17 for bending the iron wire are respectively arranged on the top of the lower pressing seat 124 and the lower bending plate 125 and on one side of the lower bending plate 125, and the output end of the second micro cylinder 123 is movably connected to the lower bending plate 125.

[0049] Specifically, there is a certain spacing between the top surface of the lower pressing seat 124 and the top surface of the lower bending plate 125 and the inner bottom wall of the lifting port 6 section, and the spacing is greater than and close to the diameter of the iron wire, which is conducive to comprehensively bending the iron wire when the lower pressing seat 124 and the lower bending plate 125 move and ensuring the stability of the bearing group after the iron wire is bent.

[0050] Preferably, a lower notch 18 is formed in the bottom side of the collection cylinder 3. The lower notch 18 corresponds to the bending notch 5 and the lower bending plate 125 respectively. The interior of the lower notch 18 is adapted to the top end of the lower pressing seat 124 and the exterior of the lower bending plate 125. The inner spacing value of the lower notch 18 is equal to the inner spacing value of the bending notch 5.

[0051] Furthermore, in combination with Figure 9 As shown, a wire guiding hopper 19 is fixedly installed on the second sliding seat 122. The inner bottom of the wire guiding hopper 19 is a U-shaped groove. The diameter value of one end inside the U-shaped groove is equal to the diameter of the iron wire. The wire guiding hopper 19 is located directly below one end of the lower bending plate 125. The center of one end inside the U-shaped groove and the center of the lower bending groove 17 on one side of the lower bending plate 125 are on the same vertical line.

[0052] Specifically, when the iron wire is placed in the inner rings of multiple bearings inside the collection cylinder 3 through the robotic arm 10, one end of the iron wire can be precisely guided into the U-shaped groove of the wire guiding hopper 19 due to the hopper-shaped design on the top side of the wire guiding hopper 19. When the iron wire is fully attached to the inner arc at the inner end in the U-shaped groove, the iron wire can be correspondingly arranged in the lower bending groove 17 of the vertical section of the lower bending plate 125, which is beneficial for the lower bending plate 125 to bend the iron wire when the second sliding seat 122 moves.

[0053] In combination with Figure 7 and Figure 10 As shown, in this embodiment, the lifting mechanism 13 includes a third air cylinder 130 installed on the support table 1, a lifting plate 131 connected to the output end of the third air cylinder 130, and a lifting support rod 132 installed on the lifting plate 131. The lifting support rod 132 corresponds to the lifting opening 6 and is adapted to the interior of the lifting opening 6.

[0054] Specifically, there are two lifting support rods 132, and there are also two corresponding lifting openings 6. The two lifting openings 6 are symmetrically arranged with the bending notch 5 as the axis of symmetry. Thus, after the lifting support rod 132 enters the lifting opening 6, through the pushing work of the third air cylinder 130, the lifting support rod 132 can push the grouped bearings to rise, ensuring the smoothness and fluency when the bearings rise. Furthermore, after the grouped bearings rise and emerge from the top of the collection cylinder 3, the robotic arm 10 can grasp the grouped bearings, and then lift the grouped bearings. After the grouped bearings are separated from the inner cavity of the collection cylinder 3, with the work of the robotic arm 10, they can be successively placed in the turnover box 14, which is convenient for later manual centralized recycling and processing of the bearings in the turnover box 14.

[0055] In combination with Figure 2As shown, in this embodiment, the wire conveying mechanism 9 includes a support 91 connected to the support table 1, a set of stepping motors 92, a gear disc group 93, a guide plate 94 mounted on the support 91, and a chain 95 meshingly connected to the corresponding gear disc group 93. A plurality of T-shaped plates 96 for pushing the wire to move are respectively connected to the surfaces of the two chains 95 close to each other. The output end of the stepping motor 92 is connected to one of the gear discs in the gear disc group 93. A set of guide plates 94 is located between the two chains 95, and the top surface of the guide plate 94 is higher than the top surface of the chain 95 during rotation.

[0056] Preferably, one end of each of the two guide plates 94 in a set is respectively provided with a corresponding material stop area, and the inner bottom of the material stop area is inclined.

[0057] Specifically, the wire cut by the wire cutting machine can be sequentially transferred to the top of the guide plate 94 and is located between every two T-shaped plates 96 at the same time. Then, when the gear disc group 93 drives the chain 95 to rotate, the T-shaped plate 96 can push the wire on the guide plate 94 forward, causing the wire to fall into the material stop area at the front section of the guide plate 94 in sequence, and the wire in the stop area is convenient for the gripper at the front end of the robotic arm 10 to grab.

[0058] Furthermore, the transfer of the cut wire can be manually placed on the guide plate 94 or controlled by other mechanical equipment. Since this article only protects the delivery of the wire to the material stop area one by one, the source of the wire is not protected and will not be elaborated in detail. And the wire cutting, transfer, and placement are all well-known and public technologies. The simplest and most cost-saving way is manual placement. This solution can adopt manual operation when there are too many doubts about the source of the wire. And in this solution, the wire conveying mechanism 9 can also be removed during actual use. A wire placement box is used to place the wire, and the robotic arm 10 clamps the wire in the box. Then, a person can place multiple wires in the box and let the robotic arm 10 continuously clamp them. When the clamping is about to be completed, the person can manually supplement the wire.

[0059] Even further, when the wire conveying mechanism 9 is in use, the stepping motor 92 is controlled by an external controller. After the robotic arm 10 clamps each wire, the stepping motor 92 rotates to make the subsequent wire enter the material stop area. And this solution only protects the physical structure and does not involve the protection of circuits and systems. It should be emphasized here that the description of the circuit and system is only a supplementary explanation for the feasibility and authenticity of this solution, and the circuit and system technologies are already well-known and public technologies, which can be programmed and implemented by those skilled in the art.

[0060] The working principle and usage process of the present invention:

[0061] When the waste bearings are loaded into the collection cylinder 3: Workers manually put a large number of waste bearings after disassembly and inspection into the vibrating disc body 7. After the vibrating disc body 7 works, it can discharge the waste bearings one by one outward, so that the discharged bearings are moved onto the conveying device 82, and the bearings are conveyed to the pusher frame 85 through the conveying device 82. Then, when the rodless cylinder 84 works to drive the pusher frame 85 to push the bearings onto the guiding member 86, the bearings can fall through the guiding holes 87 and drop into the collection cylinder 3, completing the collection of multiple waste bearings;

[0062] When tightening both ends of multiple waste bearings: After a certain amount of bearings in the collection cylinder 3 at the first station have fallen, the indexing plate device 2 can drive the collection cylinder 3 to rotate, so that the full collection cylinder 3 rotates to the second station and is located at the upper bending mechanism 11 and the lower bending mechanism 12. Then, after the indexing plate device 2 stops rotating, the robotic arm 10 clamps the iron wire. The second cylinder 121 pushes the second sliding seat 122 to move, so that after the second sliding seat 122 moves, the wire guiding hopper 19 can correspond to the center of the collection cylinder 3. Further, the robotic arm 10 sends the iron wire from the top of the collection cylinder 3 to the lower part, so that after the bottom end of the iron wire stays in the wire guiding hopper 19, the second cylinder 121 drives the second sliding seat 122 to do the reset work, prompting the lower bending plate 125 and the lower pressing seat 124 to move and bend the iron wire staying in the lower bending groove 17 by 90 degrees. Then, after the second cylinder 121 stops working, the second micro cylinder 123 works to push the lower bending plate 125 to move upward, so that the lower bending plate 125 bends the end of the iron wire by another 90 degrees. After the lower bending plate 125 completely enters the bending opening 5, the iron wire is bent in the bending opening 5 and closely adheres to the outer wall of the bearing. Then, after the robotic arm 10 releases the iron wire, the upper bending mechanism 11 works. The first cylinder 111 pushes the first sliding seat 112 to move forward, so that the upper bending plate 115 and the upper pressing seat 114 bend the top end of the iron wire by 90 degrees. And after the first sliding seat 112 moves a certain position, the first micro cylinder 113 works to push the upper bending plate 115 to rotate downward, prompting the upper bending plate 115 to bend the iron wire by 90 degrees when it enters the bending opening 5, so that both the upper and lower ends of the iron wire are bent and are in the bending opening 5 and closely adhere to the bearing, thus ensuring the fastening of both ends of the bearings in the collection cylinder 3 and avoiding the problem of bearing detachment after collection;

[0063] When taking out the grouped bearings after tightening: When the bearings inside the collection cylinder 3 at the first station are full again, the indexing plate device 2 can drive the collection cylinder 3 to rotate, so that the grouped bearings after tightening can rotate to the third station. When the third cylinder 130 works to push the lifting plate 131 to rise, the lifting support rod 132 can lift the grouped bearings in the collection cylinder 3, prompting the bearings to move upward and be exposed. Then, the robotic arm 10 can clamp and take out the grouped bearings and place the grouped bearings in the turnover box 14, which is conducive to subsequent manual unified recycling and processing of multiple grouped bearings.

[0064] In summary, this solution does not require manual threading of multiple waste bearings one by one with wire. Instead, only need to manually place the waste bearings into the vibrating disk body 7, and use the shifting and feeding mechanism 8 to collect the waste bearings in the collecting cylinder 3. After the collecting cylinder 3 is filled, use the robotic arm 10 to clamp the wire and pass it through the inner rings of multiple bearings. Then, with the help of the lower bending mechanism 12 and the upper bending mechanism 11, bend the bottom end and the top end of the wire in sequence to fasten both ends of the bearings. Finally, use the lifting mechanism 13 to cooperate with the work of the robotic arm 10, so that the grouped bearings after standardized collection can be placed into the turnover box 14, which is convenient for subsequent centralized and unified processing by workers. Different from manual standardized collection and processing, it saves time and effort, and can ensure the collection efficiency when facing a large number of waste bearings.
