Description

Technical Field

[0001] This invention relates to the field of sliding bearing production equipment technology, and more specifically to an automatic sliding bearing feeding machine and feeding method. Background Technology

[0002] Sliding bearings are essential for the operation of rotating shafts, with a large market demand and high quality requirements. Because sliding bearings have a hollow structure, automated packaging is difficult. Conventionally, individual sliding bearings are connected in series manually and then rolled and packaged by hand.

[0003] According to invention patent application CN119460247B, published on June 6, 2025, an automated packaging equipment and method for bearings is disclosed, relating to the technical field of packaging equipment. It includes an operating table and a tray installed on one side of the operating table. A bottom support rod is provided under the operating table, and a servo motor is located in the middle of the bottom support rod. A packaging device is provided on the operating table. The packaging device includes an annular inner plate rotatably mounted on the operating table, and the annular inner plate is connected to the rotating end of the servo motor. Positions one, two, and three are sequentially arranged on the operating table. Several functional cylinders are vertically arranged at equal intervals on the annular inner plate, with a support rod installed in the middle of each functional cylinder. Packaging materials are placed on the tray, and a locking mechanism is provided on the functional cylinders. A lower locking unit is provided at position three on the operating table. Its main technical effect is that it can simultaneously perform independent closed packaging operations on multiple bearings, improving the waterproof, moisture-proof, and dustproof performance of the packaged bearings, while also reducing the likelihood of damage during transportation.

[0004] After the sliding bearings are manufactured, in order to ensure their quality, they need to be rolled and packaged to reduce damage during transportation. Currently, the sliding bearings are manually connected in series and then rolled and packaged. However, manual packaging requires not only counting the number of sliding bearings but also arranging them to prevent stacking between adjacent bearings before rolling and packaging. This process is lengthy and inefficient. Therefore, an automatic sliding bearing feeding machine and feeding method are proposed to solve the problems of numerous steps and low efficiency in the existing manual rolling and packaging of sliding bearings. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic material handling machine and method for sliding bearings, which aims to solve the problems of multiple steps and low efficiency in the existing technology of manually rolling and packaging sliding bearings.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An automatic material handling machine for sliding bearings includes a vibrating feeder and a packaging machine, and further includes:

[0008] The material handling mechanism includes a material handling plate, a material handling groove is provided on the material handling plate, and a plurality of guide plates are provided in the material handling groove to divide the interior of the material handling groove into multiple material handling channels.

[0009] The feeding mechanism is located at the output end of the vibrating feeder, receives the bearings output by the vibrating feeder, and transports the bearings to one side of the material handling mechanism;

[0010] The pushing mechanism includes a first reciprocating drive unit and a lifting rake claw. The lifting rake claw is provided with a plurality of rake rods. The first reciprocating drive unit drives the rake rods on the lifting rake claw to push the bearing into the material handling channel.

[0011] The bearing moving mechanism includes a second reciprocating drive unit and a lifting clamping unit. The lifting clamping unit includes a clamping push plate and a movable push plate that maintain the lifting motion. The second reciprocating drive unit drives the clamping lifting clamping unit to maintain reciprocating movement, and pushes the bearing at one end of the material feeding channel to the other end of the material feeding plate through the clamping push plate and the movable push plate.

[0012] The discharge mechanism is located on the side of the material handling mechanism opposite to the feeding mechanism. The discharge mechanism supports the bearings output by the material handling mechanism and transfers them to the packaging machine.

[0013] Preferably, the material feeding trough includes a first straight section, a wedge-shaped section, and a second straight section connected in sequence. The first straight section is located on one side of the feeding mechanism, and the second straight section is located on one side of the discharging mechanism.

[0014] Preferably, the guide plate includes a first guide plate, a second guide plate, a third guide plate, and a central guide plate. The number of the first guide plate, the second guide plate, and the third guide plate are all multiple. The central guide plate is disposed at the center of the material handling trough. The third guide plates are evenly distributed between the material handling trough and the central guide plate. The second guide plates are disposed between the third guide plate and the inner wall of the material handling trough, between adjacent third guide plates, and between the third guide plate and the central guide plate. The first guide plates are disposed between the second guide plate and the inner wall of the material handling trough, between adjacent second guide plates, and between the second guide plate and the central guide plate.

[0015] Preferably, the material handling channels on both sides of the first guide plate form a first confluence channel at the front end, and the first confluence channel is located on one side of the front end of the second guide plate. The first confluence channels on both sides of the second guide plate form a second confluence channel at the front end, and the second confluence channel is located on one side of the front end of the third guide plate.

[0016] Preferably, the material handling mechanism further includes a material blocking component, which includes a movable baffle and an insertion slot formed at the bottom of the material handling plate. The insertion slot is connected to the material handling channel, and the movable baffle is inserted into the insertion slot to block the material handling channel.

[0017] Preferably, the feeding mechanism is provided with a circulating transmission belt, and the transmission belt is provided with clamping plates for holding bearings, with a bearing seat formed between two adjacent clamping plates.

[0018] Preferably, the discharge mechanism includes a third frame, a front positioning plate and a rear positioning plate disposed on the third frame, and a discharge clamping mechanism disposed between the front positioning plate and the rear positioning plate. The front positioning plate and the rear positioning plate maintain a certain distance from each other. Guide plates are installed on the top of both the front positioning plate and the rear positioning plate, and a feeding channel is formed between the two guide plates. The discharge clamping mechanism moves in the feeding channel.

[0019] Preferably, the discharge clamping mechanism includes a third reciprocating drive unit, a transmission chain, and a clamping rod unit disposed on the transmission chain. The transmission chain is connected to the output end of the third reciprocating drive unit, and the transmission chain is driven to move by the third reciprocating drive unit. The clamping rod unit is disposed on the transmission chain.

[0020] Preferably, the clamping rod unit includes a first clamping rod, a second clamping rod, a first connecting block, a second connecting block, and a connecting rod. The first connecting block and the second connecting block are both fixedly connected to the transmission chain. The first clamping rod is rotatably connected to one end of the connecting rod. One end of the connecting rod is rotatably connected to a guide wheel, and the other end of the connecting rod is rotatably connected to the first connecting block. A guide groove is provided on the front positioning plate, and the guide wheel is slidably connected to the guide groove.

[0021] A material handling method for the aforementioned automatic sliding bearing material handling machine includes the following steps:

[0022] The vibrating feeder feeds individual sliding bearings sequentially into the bearing housing of the feeding mechanism;

[0023] A single sliding bearing in the bearing housing of a set of clamping plates is transferred to the first straight section of the material handling plate by a transmission belt, at which point the bearing housing is aligned with the material handling channel.

[0024] The lifting rake claw drives the rake rod on the lifting rake claw to insert into the bearing seat. Then, the first reciprocating drive unit drives the rake rod to move, so that the rake rod moves in the bearing seat and pushes the bearing in the bearing seat into the material handling channel.

[0025] After the bearings enter the material feeding channel, they come into contact with multiple bearings through the movable baffle of the baffle assembly, thus restricting the rolling of the bearings.

[0026] Subsequently, the second reciprocating drive unit of the bearing moving mechanism drives the lifting clamping unit to move. The clamping push plate and the movable push plate of the lifting clamping unit descend, clamping all the bearings in the material handling channel. At the same time as the clamping push plate and the movable push plate descend, the movable baffle descends and resets.

[0027] The second reciprocating drive unit is reset. When the second reciprocating drive unit moves, the clamping push plate and the movable push plate push all the bearings to move in the material feeding channel.

[0028] When a single bearing moves, the bearings located in the material handling channels on both sides of the first guide plate merge into a first bearing group in the first confluence channel at the front end of the first guide plate, and the first bearing group moves in the first confluence channel on both sides of the front end of the second guide plate.

[0029] When a single first bearing assembly moves, the first bearing assemblies located in the first confluence channels on both sides of the front end of the second guide plate combine into a second bearing assembly and move into the second confluence channel;

[0030] When a single second bearing assembly moves, the second bearing assemblies located on both sides of the front end of the third guide plate and the bearings on both sides of the central guide plate merge into the third bearing assembly.

[0031] The third bearing assembly moves to the second straight section of the material feeding trough under the push of the second reciprocating drive unit, the clamping push plate, and the movable push plate;

[0032] Subsequently, the movable push plate rises, and the second reciprocating drive unit drives the lifting clamping unit to move, pushing the third bearing assembly into the feeding channel through the clamping push plate.

[0033] The third bearing assembly is held by the clamping rod unit, and the third reciprocating drive unit drives the transmission chain to move, transferring the third bearing assembly to the packaging machine for packaging.

[0034] The automatic material handling machine and method for sliding bearings provided by the present invention, as described above, have the following beneficial effects:

[0035] This invention receives bearings from a vibrating feed tray via a feeding mechanism and transports them to a sorting mechanism. A first reciprocating drive unit of the pushing mechanism drives a rake on a lifting rake claw to push the bearings into the sorting channel. A second reciprocating drive unit drives a clamping lifting unit to move, and a clamping push plate and a movable push plate push the bearings within the sorting channel. Through the guiding action of a guide plate, individual bearings are combined into bearing groups. The unloading mechanism then transfers the bearing groups to a packaging machine for packaging. This invention enables the sorting, counting, and merging of sliding bearings, allowing the packaging of sliding bearings to be compatible with conventional packaging machines, thereby improving the packaging efficiency of sliding bearings and replacing manual packaging, thus increasing production efficiency.

[0059] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0060] Please see Figures 1-19An automatic material handling machine for sliding bearings includes a vibrating feeder and a packaging machine, and further includes:

[0061] Material handling mechanism 1 includes a material handling plate 11, a material handling groove 12 is provided on the material handling plate 11, and a plurality of guide plates 17 are provided in the material handling groove 12, which divide the interior of the material handling groove 12 into a plurality of material handling channels 13 by the plurality of guide plates 17.

[0062] Feeding mechanism 2 is located at the output end of the vibrating feeder, receives the bearings output by the vibrating feeder, and transports the bearings to one side of the material handling mechanism 1;

[0063] The pushing mechanism 3 includes a first reciprocating drive unit 31 and a lifting rake 32. The lifting rake 32 is provided with a plurality of rake rods 33. The first reciprocating drive unit 31 drives the rake rods 33 on the lifting rake 32 to push the bearing into the material handling channel 13.

[0064] The bearing moving mechanism 4 includes a second reciprocating drive unit 41 and a lifting clamping unit 42. The lifting clamping unit 42 includes a clamping push plate 421 and a movable push plate 422 for maintaining the lifting motion. The second reciprocating drive unit 41 drives the clamping lifting clamping unit 42 to maintain reciprocating movement. The clamping push plate 421 and the movable push plate 422 push the bearing at one end of the material handling channel 13 to the other end of the material handling plate 11.

[0065] The discharge mechanism 5 is located on the side of the material handling mechanism 1 away from the feeding mechanism 2. The discharge mechanism 5 supports the bearings output by the material handling mechanism 1 and transfers them to the packaging machine.

[0066] This invention receives bearings from the vibrating feed tray via the feeding mechanism 2 and transports them to one side of the sorting mechanism 1. The first reciprocating drive unit 31 of the pushing mechanism 3 drives the rake bar 33 on the lifting rake claw 32 to push the bearings into the sorting channel 13. The second reciprocating drive unit 41 drives the clamping lifting clamping unit 42 to move. The clamping push plate 421 and the movable push plate 422 push the bearings in the sorting channel 13. After the guide plate 17 guides the bearings, the individual bearings are combined into bearing groups. The bearing groups are transferred to the packaging machine for packaging via the discharge mechanism 5. This invention can realize the sorting, counting and merging of sliding bearings, making the packaging of sliding bearings compatible with conventional packaging machines, thereby improving the packaging efficiency of sliding bearings.

[0067] As an embodiment of the present invention, the feeding mechanism 2 includes a first frame 24, a transmission belt 21, a drive motor 25 and a clamping plate 22. The drive motor 25 is mounted on the first frame 24 and its output end is connected to the transmission belt 21. A plurality of clamping plates 22 are mounted on the transmission belt 21 and a bearing seat 23 is formed between two adjacent clamping plates 22.

[0068] Specifically, the transmission belt 21 includes a first transmission belt 211 and a second transmission belt 212, and the drive motor 25 includes a first motor 251 and a second motor 252. Specifically, the first motor 251 is fixedly installed on one end of the outer wall of the first frame 24. A first drive wheel and a first driven wheel for connecting the first transmission belt 211 are provided in the first frame 24. The first transmission belt 211 is connected to the first drive wheel and the first driven wheel respectively. The output end of the first motor 251 is connected to the first drive wheel. The first drive wheel is driven by the first motor 251 to keep rotating, thereby driving the first transmission belt 211 to keep moving in the first frame 24.

[0069] To improve the efficiency of bearing transportation, a second motor 252, a second drive wheel, a second driven wheel, and a second transmission belt 212 are provided. The second motor 252 is located on the side of the first frame 24 opposite to the first motor 251. The second drive wheel and the second driven wheel are rotatably connected to the first frame 24. The output end of the second motor 252 is connected to the second drive wheel. The second motor 252 drives the second drive wheel to rotate, thereby driving the second transmission belt 212 to move within the first frame 24.

[0070] Preferably, clamping plates 22 are provided on both the first transmission belt 211 and the second transmission belt 212. Some clamping plates 22 are connected to the first transmission belt 211, and some clamping plates 22 are connected to the second transmission belt 212, so as to realize staggered transportation and improve the efficiency of bearing transportation.

[0071] Furthermore, the clamping plates 22 provided on the first transmission belt 211 and the second transmission belt 212 are in several groups, each group including multiple clamping plates 22, and a bearing seat 23 is formed between each two adjacent clamping plates 22.

[0072] Because the first transmission belt 211 and the second transmission belt 212 are driven by a drive wheel and a driven wheel, the ends of the first transmission belt 211 and the second transmission belt 212 are arc-shaped. The clamping plates 22, which were originally set at a fixed interval on the first transmission belt 211 and the second transmission belt 212, are now swinging outward at a certain angle. This makes it easier for the bearing to enter the bearing housing 23 when the vibrating feed pan and the differential conveyor belt feed a single sliding bearing into the bearing housing 23, preventing the bearing from falling out.

[0073] Furthermore, such as Figure 17 and Figure 2As shown, baffles are connected to the outer walls on both sides of one end of the first frame 24. Preferably, the baffles are installed on the outer walls on both sides of the end of the first frame 24 that is connected to the vibrating feed tray. They are used to limit the bearings entering the bearing housing 23 and prevent the bearings from coming out from the side. The baffles can also be adjusted in position according to the size of the sliding bearings being produced, and can handle sliding bearings of various sizes and specifications.

[0074] As an embodiment provided by the present invention, such as Figure 4 As shown, the pushing mechanism 3 includes a lifting rake claw 32 and a first reciprocating drive unit 31 for driving the lifting rake claw 32 to maintain reciprocating motion. Several rake rods 33 are provided on the lifting rake claw 32. Specifically, the first reciprocating drive unit 31 can be provided on the first frame 24. The first reciprocating drive unit 31 can be a linear drive module.

[0075] As an embodiment of the present invention, the first reciprocating drive unit 31 includes a first fixed plate 311, a first rotary motor 312, a third drive wheel 313, a third driven wheel 314, a first slider 315, and a first connecting transmission belt 316. The first fixed plate 311 is fixedly mounted on the first frame 24 by a bracket. The third driven wheel 314 is rotatably connected to the outer wall of one side of the first fixed plate 311 by a rotating shaft. The first rotary motor 312 is fixedly mounted on the outer wall of one side of the first fixed plate 311, and the output end of the first rotary motor 312 penetrates and extends to the outer wall of the other side of the first fixed plate 311. The third drive wheel 313 is fixedly mounted on the first rotary motor 312 located on the first fixed plate. On the other output end of 311, the first connecting transmission belt 316 is connected to the third drive wheel 313 and the third driven wheel 314. The third drive wheel 313 is driven to rotate by the first rotating motor 312, thereby keeping the first connecting transmission belt 316 moving. A slide rail is provided on the first fixed plate 311, and the first slider 315 is slidably connected to the slide rail. The first slider 315 is also fixedly connected to one side of the first connecting transmission belt 316. While the first rotating motor 312 drives the first connecting transmission belt 316 to move, it can also drive the first slider 315 to move on the slide rail, thereby driving the lifting rake 32 to reciprocate on the first fixed plate 311. A first fixed bracket 317 is fixedly installed on the first slider 315.

[0076] Furthermore, the lifting rake claw 32 includes a first lifting unit 321 and a rake rod mounting plate 322 connected to the first fixed bracket 317. The first lifting unit 321 is fixedly installed on the first fixed bracket 317, and the rake rod mounting plate 322 is fixedly installed on the output end of the first lifting unit 321. A plurality of rake rods 33 are fixedly installed on the rake rod mounting plate 322, and the rake rods 33 are distributed in a linear array on the rake rod mounting plate 322.

[0077] The first lifting unit 321 can be a cylinder.

[0078] The number of rakes 33 is matched with the number of material handling channels 13, and the installation position of the rakes 33 is also matched with the opening position of the material handling channels 13, so that when the first reciprocating drive unit 31 drives the lifting rake claw 32 to move, the rakes 33 can be inserted into the material handling channels 13 from the side and push the bearing.

[0079] As a further embodiment of the present invention, the material handling mechanism 1 includes a second frame 18 and a material handling plate 11 disposed on the second frame 18. A material handling groove 12 is provided on the material handling plate 11. The material handling groove 12 includes a first straight section 121, a wedge-shaped section 122 and a second straight section 123. The width of the first straight section 121 is adapted to the total length of part of the clamping plate 22 of the feeding mechanism 2, so as to ensure that the sliding bearing in the bearing seat 23 can move from the bearing seat 23 to the material handling groove 12.

[0080] Preferably, an L-shaped plate is provided at the outlet of the second straight section 123 of the feeding plate 11 to prevent the bearing from falling out and to allow the third bearing assembly 8 to enter the feeding channel 56 more easily.

[0081] Several guide plates 17 are provided inside the material handling tank 12, which divide the material handling tank 12 into multiple material handling channels 13.

[0082] As a further embodiment of the present invention, for example Figure 9 and Figure 10 As shown, the guide plate 17 includes a first guide plate 171, a second guide plate 172, a third guide plate 173, and a central guide plate 174. The central guide plate 174 is located at the center of the material handling trough 12. There are several first guide plates 171, second guide plates 172, and third guide plates 173. The third guide plates 173 are evenly distributed between the inner wall of the material handling trough 12 and the central guide plate 174. The second guide plates 172 are located between the third guide plates 173 and the inner wall of the material handling trough 12, between adjacent third guide plates 173, and between the third guide plates 173 and the central guide plate 174. The first guide plates 171 are located between the second guide plates 172 and the inner wall of the material handling trough 12, between adjacent second guide plates 172, and between the second guide plates 172 and the central guide plate 174.

[0083] The material handling trough 12 is divided into multiple material handling channels 13 by the first guide plate 171, the second guide plate 172, the third guide plate 173 and the central guide plate 174. The number of material handling channels 13 is adapted to the number of bearing seats 23. When the clamping plate 22 is moved to the end of the material handling plate 11 by the transmission belt 21, the bearing seats 23 correspond to the material handling channels 13, which facilitates the sliding bearing to enter the material handling channels 13.

[0084] On the material handling plate 11, the end closer to the second straight section 123 is the front end, and the end closer to the first straight section 121 is the rear end.

[0085] The material handling channels 13 on both sides of the first guide plate 171 form a first confluence channel 14 at the front end of the first guide plate 171, and the first confluence channel 14 is located on one side of the second guide plate 172, such as... Figure 10 As shown, the front sides of the second guide plate 172 are both first confluence channels 14, and the first confluence channels 14 merge into a second confluence channel 15 after passing through the second guide plate 172. The rear sides of the second guide plate 172 are material handling channels 13, and the front ends of the third guide plate 173 and the central guide plate 174 are second straight sections 123.

[0086] When the sliding bearings in the material handling channels 13 on both sides of the first guide plate 171 move in the material handling channels 13, the lateral distance between the sliding bearings in the material handling channels 13 on both sides of the first guide plate 171 gradually shortens under the guidance of the wedge structure of the first guide plate 171 and the wedge section 122 of the inner wall of the adjacent second guide plate 172 or material handling trough 12. When they enter the first confluence channel 14, under the action of the wedge structure, the two sliding bearings gradually approach and fit together, merging into the first bearing group 6. Since there is lubricating oil attached to the sliding bearings, the two sliding bearings maintain a certain adsorption through the adsorption effect of the lubricating oil. The first bearing group 6, after passing through the second guide plate 172 and multiple independent sliding bearings in the individual material handling tank 12, gradually passes through the first merging channel 14, the second merging channel 15, and the second straight section 123, forming a first bearing group 6 where a single bearing is merged into two bearings. The first bearing group 6, consisting of two bearings, is then merged into a second bearing group 7, consisting of four bearings. The second bearing group 7, consisting of four bearings, is finally merged into a third bearing group 8. This step-by-step merging of multiple independent bearings effectively prevents misalignment and intrusion into the cavity that can easily occur when hollow sliding bearings are merged. At the same time, the number of sliding bearings can be counted through the bearing seat 23 and the material handling channel 13. That is, the number of sliding bearings entering the material handling channel 13 each time is limited, enabling automatic counting of sliding bearing packaging.

[0087] Furthermore, the portions of the first guide plate 171, the second guide plate 172, and the third guide plate 173 near the rear end of the material handling plate 11 are planar structures, set within the first straight section 121, for matching with the bearing housing 23 and guiding a single bearing into the material handling channel 13. Preferably, the outer walls on both sides of the first guide plate 171, the second guide plate 172, the third guide plate 173, and the central guide plate 174 near the rear end of the material handling plate 11 are wedge-shaped structures, which can provide good guidance when the bearing enters the material handling channel 13 from the bearing housing 23, reducing the jamming and offset of the bearing when entering the material handling channel 13.

[0088] As an embodiment of the present invention, the length of the first straight section 121 accounts for 13%-16% of the total length of the material handling trough 12, preferably 14.91%; the length of the second straight section 123 accounts for 15%-19% of the total length of the material handling trough 12, preferably 17.54%; and the length of the wedge-shaped section 122 accounts for 65%-69% of the total length of the material handling trough 12, preferably 67.55%.

[0089] The first straight section 121 is used to receive a single bearing output from the feeding mechanism 2, and the wedge section 122 is used to merge and organize multiple bearings, assisting in merging a single bearing into multiple bearing groups.

[0090] The front ends of the first guide plate 171, the second guide plate 172, and the third guide plate 173 are all wedge-shaped structures facing the central guide plate 174.

[0091] It should be noted that the angle of the wedge segment 122 is determined based on the total length of the first straight segment 121 and the total length of the second straight segment 123. The angles of the wedge structures at the front ends of the first guide plate 171, the second guide plate 172 and the third guide plate 173 gradually increase based on the angle of the wedge segment 122 to ensure the material handling, guidance and merging effect of the sliding bearing.

[0092] The total length of the first guide plate 171 accounts for 43%-47% of the total length of the material handling trough 12, preferably 45.61%. The total length of the second guide plate 172 accounts for 68%-72% of the total length of the material handling trough 12, preferably 70.18%. The total length of the third guide plate 173 and the total length of the central guide plate 174 both account for 76%-80% of the total length of the material handling trough 12, preferably 78.95%.

[0093] The length of the wedge-shaped structure on the first guide plate 171 accounts for 71%-75% of the total length of the first guide plate 171, preferably 73.08%.

[0094] The length of the wedge structure on the second guide plate 172 accounts for 80%-84% of the total length of the second guide plate 172, preferably 82.5%.

[0095] The length of the wedge structure on the third guide plate 173 accounts for 82%-86% of the total length of the third guide plate 173, preferably 84.44%.

[0096] like Figure 9 and Figure 10As shown, the starting ends of the wedge-shaped structures of the first guide plate 171, the second guide plate 172, and the third guide plate 173 are all located within the first straight section 121, so that when the bearing moves into the first straight section 121, it can move smoothly into the first guide plate 171, the second guide plate 172, and the third guide plate 173.

[0097] In this embodiment, as Figure 19 As shown, the bearings located in the material handling channels 13 on both sides of the middle material handling channel 13 can gradually converge towards the middle under the action of the first guide plate 171, the second guide plate 172 and the third guide plate 173 when they move, so as to merge two adjacent independent bearings into the first bearing group 6, merge the adjacent first bearing group 6 into the second bearing group 7, and then merge two adjacent second bearing groups 7 into the complete third bearing group 8. This realizes the step-by-step merging and integration of sliding bearings, which is convenient for subsequent packaging.

[0098] As one embodiment provided by the present invention, such as Figure 10 As shown, there are two central guide plates 174, which are symmetrically arranged at the center of the material handling tank 12, and a material handling channel 13 is formed between the two central guide plates 174.

[0099] As another embodiment of the present invention, there is one central guide plate 174, which is set at the center of the material handling tank 12, and material handling channels 13 are formed between the two sides of the central guide plate 174 and the first guide plate 171 respectively.

[0100] It should be noted that the width of the material handling channel 13 provided in this embodiment of the invention can be designed according to the model of the bearing being produced.

[0101] The hierarchical merging structure formed by the first guide plate 171, the second guide plate 172, the third guide plate 173, and the central guide plate 174 merges multiple independent and dispersed bearings into a tightly connected third bearing group 8. This effectively prevents hollow sliding bearings from tipping over during the merging process, which could cause one sliding bearing to intrude into the cavity of another. Specifically, for example... Figure 18 The diagram shows the rolling state of a sliding bearing. Without a step-by-step merging structure, the gap between the bearings is large when they merge, which can easily cause one sliding bearing to intrude into the cavity of another. Through the step-by-step merging structure formed by the first guide plate 171, the second guide plate 172, the third guide plate 173 and the central guide plate 174 provided in this embodiment of the invention, efficient material handling of the sliding bearing can be achieved.

[0102] As a further embodiment of the material handling mechanism 1 provided by the present invention, the material handling mechanism 1 also includes a material blocking component 16. The material blocking component 16 includes a movable baffle 161 and an insertion groove 162 opened at the bottom of the material handling plate 11. The insertion groove 162 is connected to the material handling channel 13. The movable baffle 161 is inserted into the insertion groove 162 to block the material handling channel 13.

[0103] A lifting drive unit 163 is fixedly installed on the outer wall at the bottom of the material handling plate 11. A movable baffle 161 is fixedly connected to the output end of the lifting drive unit 163. The lifting drive unit 163 drives the movable baffle 161 to keep lifting and lowering, so that the movable baffle 161 moves in the insertion slot 162. When the movable baffle 161 rises, it can isolate the material handling channel 13.

[0104] As an embodiment of the present invention, the lifting drive unit 163 can be a cylinder.

[0105] A positioning groove is provided in the material feeding trough 12. The positioning groove is located in the first straight section 121. The positioning groove can limit the sliding bearing when it enters the material feeding channel 13, and is used to cooperate with the material blocking assembly 16 to limit the bottom of the sliding bearing.

[0106] As a further embodiment provided by the present invention, such as Figure 6 , Figure 7 and Figure 8 As shown, it also includes a bearing moving mechanism 4, which includes a second reciprocating drive unit 41 and a lifting clamping unit 42. The second reciprocating drive unit 41 is mounted on the second frame 18, and the lifting clamping unit 42 is mounted on the second reciprocating drive unit 41. The second reciprocating drive unit 41 drives the lifting clamping unit 42 to maintain reciprocating motion so as to push the bearing from the feeding mechanism 2 to the discharging mechanism 5.

[0107] The second reciprocating drive unit 41 can be a linear module.

[0108] As an embodiment of the present invention, the second reciprocating drive unit 41 further includes a second fixed plate 411, a second rotary motor 412, a fourth drive wheel 413, a fourth driven wheel 414, a second transmission belt 212, and a second slider 415. The second fixed plate 411 is fixedly connected to the second frame 18 by a bracket. The second rotary motor 412 is fixedly installed on the outer wall of one side of the second fixed plate 411, and the output end of the second rotary motor 412 passes through the second fixed plate 411. The fourth drive wheel 413 is fixedly installed on the output end of the second rotary motor 412 that passes through the second fixed plate 411. The fourth driven wheel 414 is rotatably connected to the second fixed plate 18. On the second fixed plate 411, the second transmission belt 212 is connected to the fourth driven wheel 414 and the fourth driving wheel 413. A slide rail is fixedly installed on the outer wall of one side of the second fixed plate 411. The second slider 415 is slidably connected to the slide rail and fixedly connected to the second transmission belt 212 on one side. When the second rotating motor 412 drives the fourth driving wheel 413 to rotate, it drives the second transmission belt 212 to keep rotating. The rotation of the second transmission belt 212 drives the second slider 415 to keep moving on the slide rail. The rotation direction of the second rotating motor 412 is controlled by the control unit to realize the reciprocating motion of the second slider 415.

[0109] A second fixed bracket 416 is fixedly connected to the second slider 415. A lifting clamping unit 42 is fixedly connected to the second fixed bracket 416. The lifting clamping unit 42 includes a second lifting unit 423, a third lifting unit 424, a connecting bracket 425, a clamping push plate 421, and a movable push plate 422. The second lifting unit 423 is fixedly connected to the second fixed bracket 416, the connecting bracket 425 is fixedly connected to the second lifting unit 423, and the third lifting unit 424 is fixedly installed on the connecting bracket 425. The clamping push plate 421 is connected to the output end of the third lifting unit 424. The clamping push plate 421 includes a positioning push plate 4211 and a limiting push plate 4212. The positioning push plate 4211, the limiting push plate 4212 and the movable push plate 422 are all "L" shaped structures. The limiting push plate 4212 is fixedly installed at the output end of the third lifting unit 424. A sliding groove is provided on the limiting push plate 4212. The positioning push plate 4211 is connected to the limiting push plate 4212 by screws and the sliding groove, so that the distance between the positioning push plate 4211 and the limiting push plate 4212 can be adjusted by screws. It can be adapted to the production of bearings of various specifications. The positioning push plate 4211 and the limiting push plate 4212 are installed in the same direction.

[0110] The movable push plate 422 is fixedly installed on the output end of the second lifting unit 423. Furthermore, an avoidance groove 4221 is provided on the movable push plate 422. Specifically, the avoidance groove 4221 is located at the center of the outer wall of one side of the movable push plate 422, and the width of the avoidance groove 4221 is adapted to the width of the limiting push plate 4212. The limiting push plate 4212 is slidably connected to the avoidance groove 4221.

[0111] Both the second lifting unit 423 and the third lifting unit 424 can be cylinders.

[0112] As a further embodiment of the present invention, the discharge mechanism 5 includes a third frame 51, a front positioning plate 52 and a rear positioning plate 53 disposed on the third frame 51, and a discharge clamping mechanism 54 disposed between the front positioning plate 52 and the rear positioning plate 53. A certain distance is maintained between the front positioning plate 52 and the rear positioning plate 53. Guide plates 55 are installed on the top of both the front positioning plate 52 and the rear positioning plate 53, forming a feeding channel 56 between the two guide plates 55. The discharge clamping mechanism 54 moves within the feeding channel 56. A limit baffle 57 is fixedly installed on the guide plate 55 of the rear positioning plate 53 to prevent the bearing from dislodging when it enters the feeding channel 56.

[0113] like Figure 15 As shown, an optical axis 59 can also be slidably installed on the front positioning plate 52 and the rear positioning plate 53 and fastened with screws to achieve adjustable spacing. It is used to circumferentially abut against the sliding bearing assembly, provide guidance, and assist in clamping the bearing assembly.

[0114] The discharge clamping mechanism 54 includes a third reciprocating drive unit 541, a transmission chain 542, and clamping rod units 543 disposed on the transmission chain 542. The transmission chain 542 is connected to the output end of the third reciprocating drive unit 541, and the transmission chain 542 is driven to move by the third reciprocating drive unit 541. The clamping rod units 543 are disposed on the transmission chain 542, and there are multiple clamping rod units 543, which are evenly distributed on the transmission chain 542.

[0115] The third reciprocating drive unit 541 includes a servo motor 5411, a first synchronous pulley 5412, a second synchronous pulley 5413, and a transmission synchronous belt 5414. The servo motor 5411 is fixedly mounted on the outer wall of one side of the front positioning plate 52, and the output end of the servo motor 5411 passes through the front positioning plate 52. The first synchronous pulley 5412 is fixedly mounted on the output end of the servo motor 5411 that passes through the front positioning plate 52. The second synchronous pulley 5413 is rotatably connected to the front positioning plate 52. The transmission synchronous belt 5414 is connected to the first synchronous pulley 5412 and the second synchronous pulley 5413. The servo motor 5411 drives the first synchronous pulley 5412 to rotate, thereby keeping the transmission synchronous belt 5414 moving. The clamping rod unit 543 is disposed on the transmission chain 542. When the transmission synchronous belt 5414 keeps moving, it drives the transmission chain 542 to keep moving, thereby driving the clamping rod unit 543 to keep moving.

[0116] The transmission chain 542 is fixedly connected to the synchronous belt 5414. Specifically, the transmission chain 542 includes a first link 5421 and a second link 5422 connected in sequence. A connecting lug 5423 is provided on the first link 5421, which can be connected to the synchronous belt 5414 by screws. By fixing multiple first links 5421 to the synchronous belt 5414, the transmission chain 542 is connected to the synchronous belt 5414, so that the transmission chain 542 can be driven to keep moving while the servo motor 5411 drives the synchronous belt 5414 to move.

[0117] Furthermore, a guide groove 58 is provided on the front positioning plate 52. Specifically, the guide groove 58 has an overall annular structure, such as... Figure 13 and Figure 14 As shown, the guide groove 58 includes a small diameter end 581 and a large diameter end 582, and the small diameter end 581 and the large diameter end 582 are connected by a wedge-shaped guide part 583.

[0118] A clamping rod unit 543 is provided on the transmission chain 542. The clamping rod unit 543 includes a first clamping rod 5431, a second clamping rod 5432, a first connecting block 5433, and a second connecting block 5434. Specifically, the first connecting block 5433 and the second connecting block 5434 are both fixedly installed on the transmission chain 542. The first clamping rod 5431 is rotatably connected to the first connecting block 5433, and the second clamping rod 5432 is fixedly connected to the second connecting block 5434.

[0119] A rotating shaft is fixedly installed on the outer wall of one side of the first connecting block 5433. A connecting rod 5435 is rotatably connected to the rotating shaft. A first clamping rod 5431 is rotatably connected to the connecting rod 5435. Preferably, the first clamping rod 5431 rotates with the connecting rod 5435 through the rotating shaft on the first connecting block 5433. A guide wheel 5436 is rotatably connected to the outer wall of one side of the connecting rod 5435. The guide wheel 5436 is slidably connected to the guide groove 58 opened on the front positioning plate 52. When the servo motor 5411 drives the transmission synchronous belt 5414 to keep moving, it can synchronously drive the transmission chain 542 to move. While the transmission chain 542 moves, it can drive the first clamping rod 5431 and the second clamping rod 5432 to move. Since the first clamping rod 5431 is slidably connected to the guide groove 58 through the guide wheel 5436, the guide wheel 5436 slides in the guide groove 58 while the first clamping rod 5431 moves.

[0120] Preferably, the wedge-shaped guide portion 583 is disposed below the second straight section 123 of the material handling groove 12. When the first clamping rod 5431 enters the wedge-shaped guide portion 583 from the large-diameter end 582, since one side of the outer wall of the first clamping rod 5431 is rotatably connected to the first connecting block 5433, and the other side of the outer wall is slidably connected to the guide groove 58 through the guide wheel 5436, the first clamping rod 5431 can rotate when entering the wedge-shaped guide portion 583, so that the clamping rod unit 543 opens, making it easier for the bearing assembly arranged by the material handling mechanism 1 to enter the clamping rod unit 543. After the material handling mechanism 1 enters the clamping rod unit 543, under the drive of the servo motor 5411, the first clamping rod 5431 and the second clamping rod 5432 continue to move, the first clamping rod 5431 resets, and the bearing assembly is clamped by the first clamping rod 5431 and the second clamping rod 5432 to prevent the bearing assembly from loosening.

[0121] The design of the wedge-shaped guide part 583 of the guide groove 58 makes it easier for the third bearing assembly 8 to enter the feeding channel 56. When the transmission chain 542 moves, the first clamping rod 5431 can clamp the third bearing assembly 8 to prevent the third bearing assembly 8 from loosening during conveying.

[0122] Furthermore, a tension spring 5437 is provided between the first clamping rod 5431 and the connecting rod 5435. The tension spring 5437 connects the first clamping rod 5431 and the connecting rod 5435, allowing the first clamping rod 5431 to rotate toward the connecting rod 5435. When clamping bearing assemblies, the first clamping rod 5431 and the second clamping rod 5432 can accommodate a certain number of bearing assemblies, making them suitable for various packaging specifications. Simultaneously, the tension spring 5437 ensures a relatively tight grip between the bearing assemblies, preventing them from loosening. It should be noted that the specific installation method of the tension spring 5437 is a conventional technique in this field and will not be elaborated here. Additionally, a rotation limit should be provided between the first clamping rod 5431 and the connecting rod 5435 to prevent excessive rotation of the first clamping rod 5431 under the action of the tension spring 5437.

[0123] The automatic sliding bearing feeder provided in this invention can realize the entire process of sorting, counting, merging and conveying individual sliding bearings to the packaging machine, which can greatly improve the production efficiency of sliding bearings.

[0124] It should be noted that the automatic material handling machine for sliding bearings provided in this embodiment of the invention can be applied not only to sliding bearings, but also to the material handling and sorting of rolling bearings.

[0125] A material handling method applied to the above-mentioned automatic sliding bearing material handling machine includes the following steps:

[0126] The vibrating feeder feeds individual sliding bearings sequentially into the bearing housing 23 of the feeding mechanism 2;

[0127] The single sliding bearing in the bearing seat 23 of a set of clamping plates 22 is transferred to the first straight section 121 of the material handling plate 11 by the transmission belt 21, at which time the bearing seat 23 is aligned with the material handling channel 13.

[0128] The lifting rake claw 32 drives the rake rod 33 on the lifting rake claw 32 to insert into the bearing seat 23. Then, the first reciprocating drive unit 31 drives the rake rod 33 to move, so that the rake rod 33 moves in the bearing seat 23 and pushes the bearing in the bearing seat 23 into the material handling channel 13.

[0129] After the bearing enters the material feeding channel 13, it abuts against multiple bearings through the movable baffle 161 of the baffle assembly 16 to restrict the rolling of the bearing;

[0130] Subsequently, the second reciprocating drive unit 41 of the bearing moving mechanism 4 drives the lifting clamping unit 42 to move. The clamping push plate 421 and the movable push plate 422 of the lifting clamping unit 42 descend, clamping all the bearings in the material handling channel 13. At the same time as the clamping push plate 421 and the movable push plate 422 descend, the movable baffle 161 descends and resets.

[0131] The second reciprocating drive unit 41 is reset. When the second reciprocating drive unit 41 moves, the clamping push plate 421 and the movable push plate 422 push all the bearings to move within the material handling channel 13.

[0132] When a single bearing moves, the bearings in the material handling channels 13 located on both sides of the first guide plate 171 merge into a first bearing group 6 in the first confluence channel 14 at the front end of the first guide plate 171, and the first bearing group 6 moves in the first confluence channel 14 on both sides of the front end of the second guide plate 172.

[0133] When a single first bearing assembly 6 moves, the first bearing assembly 6 located in the first confluence channel 14 on both sides of the front end of the second guide plate 172 merges into the second bearing assembly 7 and moves into the second confluence channel 15.

[0134] When a single second bearing assembly 7 moves, the second bearing assembly 7 located on both sides of the second confluence channel 15 at the front end of the third guide plate 173 and the bearings on both sides of the central guide plate 174 merge into the third bearing assembly 8.

[0135] The third bearing assembly 8 moves into the second straight section 123 of the material feeding trough 12 under the push of the second reciprocating drive unit 41, the clamping push plate 421, and the movable push plate 422;

[0136] Subsequently, the movable push plate 422 rises, and the second reciprocating drive unit 41 drives the lifting clamping unit 42 to move, and pushes the third bearing group 8 into the feeding channel 56 through the clamping push plate 421.

[0137] The third bearing assembly 8 is held by the clamping rod unit 543, and the third reciprocating drive unit 541 drives the transmission chain 542 to move, so as to transfer the third bearing assembly 8 to the packaging machine for packaging.

[0138] Taking the production of a single bearing as an example, the sliding bearing is transported individually by a vibrating feeding tray and a differential conveyor belt, and then individually fed into the bearing housing 23. A photoelectric sensor can be set at one end of the differential conveyor belt near the feeding mechanism 2. When the photoelectric sensor detects that the bearing has passed, the control unit controls the first motor 251 and the second motor 252 to rotate, driving the first transmission belt 211 and the second transmission belt 212 to move, thereby opening the next bearing housing 23 and moving the bearing housing 23 containing the bearing.

[0139] After all the bearing seats 23 of a set of clamping plates 22 are filled with sliding bearings, a photoelectric sensor can be set on the first frame 24 to detect whether the clamping plates 22 have moved to the position. When the clamping plates 22 have moved to the position, it means that all the bearing seats 23 are filled with bearings. The first motor 251 and the second motor 252 drive the first transmission belt 211 and the second transmission belt 212 to move, moving a set of clamping plates 22 to the end of the material feeding groove 12 in the material feeding plate 11 of the material feeding mechanism 1. It should be noted that, by design, after the first transmission belt 211 and the second transmission belt 212 move to the position, the position of the bearing seat 23 corresponds to the material feeding channel 13, so as to ensure that the middle bearing in the bearing seat 23 can move into the material feeding channel 13.

[0140] Subsequently, the first reciprocating drive unit 31 drives the lifting rake claw 32 to keep moving, so that the lifting rake claw 32 moves to the end of the clamping plate 22 away from the material handling mechanism 1. The first lifting unit 321 of the lifting rake claw 32 drives the rake rod mounting plate 322 to descend, so that the rake rod 33 mounted on the rake rod mounting plate 322 can be inserted into the bearing seat 23. The first reciprocating drive unit 31 drives the lifting rake claw 32 to move, and the rake rod 33 abuts against the sliding bearing, driving the sliding bearing to roll from the bearing seat 23 into the material handling plate 11.

[0141] After the bearing moves into the material feeding channel 13, the movable baffle 161 of the baffle assembly 16 provided at the bottom of the material feeding plate 11 isolates the material feeding channel 13, preventing the bearing from rolling disorderly in the material feeding channel 13. Meanwhile, as Figure 7 As shown, the positioning groove opened on the feed plate 11 can engage with the bearing peripheral wall to further prevent the bearing from rolling.

[0142] Subsequently, the second reciprocating drive unit 41 drives the lifting clamping unit 42 to move to the first straight section 121 of the material handling plate 11. The second lifting unit 423 and the third lifting unit 424 of the lifting clamping unit 42 respectively drive the clamping push plate 421 to descend. The clamping push plate 421 and the movable push plate 422 clamp the bearings in the multiple material handling channels 13 located at the movable baffle 161. The sliding bearings are limited by the clamping push plate 421 and the movable push plate 422.

[0143] Subsequently, the second lifting unit 423 of the baffle assembly 16 drives the movable baffle 161 to descend, and drives the lifting clamping unit 42 to move toward the second straight section 123 of the material handling plate 11 via the second reciprocating drive unit 41.

[0144] During the movement of the bearing, the clamping push plate 421 and the movable push plate 422 limit the two ends of multiple bearings to prevent the bearings from moving too fast. At the same time, since the bearings are located in the material handling channel 13, the material handling plate 11 can be used to position the axial side of the bearings to prevent the bearings from tipping over.

[0145] As the bearings move from the first straight section 121 to the wedge section 122, multiple bearings enter the wedge structures of the first guide plate 171, the second guide plate 172, and the third guide plate 173 respectively, and move along the wedge structures of the first guide plate 171, the second guide plate 172, and the third guide plate 173. During the movement, because the bearings are limited in the front and rear directions by the clamping push plate 421 and the movable push plate 422, the bearings only move in the horizontal direction. Therefore, under the guidance of the wedge structures of the first guide plate 171, the second guide plate 172, and the third guide plate 173, each bearing will only move towards the central guide plate 174.

[0146] When the bearings in the material handling channels 13 on both sides of the first guide plate 171 move to the front end of the first guide plate 171, the two bearings will enter the first confluence channel 14. After the two bearings enter the first confluence channel 14, the two bearings will approach each other and gradually come closer together through the guiding action of the wedge structure of the second guide plate 172 and the wedge section 122 of the material handling trough 12, so that the two bearings merge into the first bearing group 6. Since the bearings contain some lubricating oil, there is a certain adsorption force between the bearings. After the two bearings merge, they will maintain a certain adsorption state. Then, under the push of the clamping push plate 421 and the movable push plate 422, the first bearing group 6 formed by the merger of the two bearings will continue to move in the first confluence channel 14. When the first bearing group 6 moves to the second confluence channel 15 at the front end of the second guide plate 172, under the action of the wedge structure of the second guide plate 172, the wedge structure of the third guide plate 173 and the wedge section 122 of the material handling trough 12, the adjacent first bearing groups 6 will approach each other and merge into the second bearing group 7 composed of four bearings.

[0147] Under the action of the clamping push plate 421, the second bearing group 7 composed of four bearings continues to move forward. When the second bearing group 7 composed of four bearings moves out of the third guide plate 173, it will gradually approach and move to the second straight section 123, merging multiple second bearing groups 7 into a complete third bearing group 8, which is convenient for packaging. This realizes the merging of multiple dispersed bearings into a complete bearing group, replacing manual counting and sorting.

[0148] It should be noted that when there are two central guide plates 174, the two central guide plates 174 are parallel structures, which can directly transport the bearing in the material handling channel 13 to the second straight section 123, and the bearing can be directly combined with multiple third bearing groups 8.

[0149] When the bearing assembly is inside the second straight section 123, the second lifting unit 423 drives the movable push plate 422 to rise. At this time, the bearing assembly inside the second straight section 123 is limited by the clamping push plate 421.

[0150] As designed, when the bearing assembly is located in the second straight section 123, the servo motor 5411 drives the transmission synchronous belt 5414 to move, causing the first clamping rod 5431 of the clamping rod unit 543 on the transmission chain 542 to rotate and open. Then, the second reciprocating drive unit 41 drives the clamping push plate 421 to move, pushing the bearing assembly into the feeding channel 56. Subsequently, the servo motor 5411 drives the transmission synchronous belt 5414 to move, moving the bearing assembly into the packaging machine for packaging.

[0151] The tension spring 5437 mentioned in this article has an elastic coefficient that meets the technical requirements of the technical solution of this invention.

[0152] It should be noted that the vibrating feeder, differential conveyor belt, and packaging machine mentioned in the embodiments of the present invention are all conventional equipment in the prior art, and therefore are not shown in the accompanying drawings.

[0153] like Figure 1 As shown, to improve aesthetics and protection, a cover can be installed on the first frame 24. The cover can be a conventional structure in the prior art, so it will not be described here.

[0154] The automatic sliding bearing feeding machine and feeding method provided in the embodiments of the present invention also include other functional modules, such as electrical components, control units, etc., which should be known to those skilled in the art, and will not be described in detail here.

[0155] Those skilled in the art will understand that other similar connection methods can also achieve the present invention. For example, welding, bonding, or screwing.

[0156] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
