Description

Technical Field

[0001] The invention relates to the technical field of bearing roller assembly, in particular to a bearing roller distributor. Background Art

[0002] Bearing assembly involves fitting the rollers between the inner and outer rings. The rotation of the rollers allows the inner and outer rings to roll relative to each other, creating a rotational connection. Bearing rollers are typically stored in packaging trays before assembly. Currently, these rollers are manually removed and placed on the assembly line for transport and assembly. This manual process is time-consuming and labor-intensive, resulting in inaccurate counting. During handling, rollers can fall (causing deformation) or collide with each other, potentially resulting in substandard packaging (which can affect the quantity or quality of the rollers).

[0003] Therefore, a bearing roller feeder is needed to overcome the above problems. Summary of the Invention

[0004] In order to solve the above problems, an embodiment of the present invention provides a bearing roller distributor, comprising a pushing device, a temporary stacking device and a conveying device, wherein:

[0005] The conveying device includes a conveying channel and a first power mechanism located on one side of the conveying channel. The width of the conveying channel is slightly larger than the large end diameter of the bearing roller. The bearing roller moves from the first end to the second end of the conveying channel under the drive of the first power mechanism.

[0006] The temporary stacking device includes a third power mechanism, an equal number of at least two fixed inclined platforms and a movable inclined platform, wherein:

[0007] The fixed ramp is located beside the second end of the conveying channel and is used to receive the bearing roller from the second end of the conveying channel. All the fixed ramps are arranged at intervals. The fixed ramps have a fixed support surface with a normal line inclined toward the direction of the conveying channel. The upper end of the fixed ramp is lower than the upper surface of the conveying channel.

[0008] A movable ramp is installed on a side of each fixed ramp away from the conveying channel, wherein the movable ramp has a movable supporting surface inclined in a direction away from the conveying channel, and the movable ramp is movably arranged in a vertical direction under the drive of the third power mechanism; and

[0009] The ejection device includes a fourth power mechanism, which is located on the side of the temporary stacking device away from the second end of the conveying channel. Under the drive of the fourth power mechanism, the bearing rollers in the packaging tray are pushed along their own axial direction and stacked on the movable inclined platform located at the bottom dead center.

[0010] Furthermore, the conveying channel includes two baffles, the two baffles are arranged opposite to each other, and the first power mechanism is located between the two baffles.

[0011] Furthermore, the width of the conveying channel first increases and then decreases in a direction from top to bottom, and the width of the upper end of the conveying channel and the width of the lower end of the conveying channel are both smaller than the small end diameter of the bearing roller.

[0012] Furthermore, the inner surface of the baffle is an inner cylindrical surface whose axis coincides with the axis of the bearing roller located in the conveying channel.

[0013] Furthermore, the first power mechanism includes a first power unit, a driven belt roller, a driving belt roller driven by the first power unit, and a conveyor belt sleeved on the driving belt roller and the driven belt roller.

[0014] Furthermore, it also includes an end-changing device, which includes a fifth power mechanism and an end-changing plate that can rotate in a horizontal plane under the drive of the fifth power mechanism, and the end-changing plate is located at the second end of the conveying channel.

[0015] Furthermore, it also includes a controller and a first detection unit and a second detection unit both connected to the controller by signal, and the control end of the first power mechanism, the control end of the third power mechanism, the control end of the fourth power mechanism, and the control end of the fifth power mechanism are all connected to the controller by signal, wherein:

[0016] The first detection unit is fixed above the conveying channel, and the distance between the first detection unit and the first end of the conveying channel is not greater than the length of the fixed support surface. The controller is configured as follows:

[0017] When the first detection unit continuously detects the bearing roller for the first time within a time T1 in a cycle, the first power mechanism is started, and the third power mechanism and the fourth power mechanism are stopped, so as to push the bearing roller on the carrying plate onto the conveyor belt;

[0018] When the first detection unit continuously detects that the bearing roller cannot be detected within time T2, the first power mechanism, the third power mechanism, and the fourth power mechanism are controlled to continue to operate;

[0019] The second detection unit is fixed above the movable ramp at the maximum distance from the conveying channel, and the controller is configured to start the third power mechanism within time T3 after the second detection unit detects the bearing roller, so as to push the bearing roller on the temporary stacking device toward the supporting plate.

[0020] Furthermore, it also includes a second power mechanism installed at the first end of the conveyor belt, wherein the control end of the second power mechanism is connected to the controller signal, and the bearing roller carried on the carrying plate is pushed toward the conveyor belt under the drive of the second power mechanism;

[0021] The second power mechanism, the third power mechanism and the fourth power mechanism are all cylinders.

[0022] Furthermore, the fifth power mechanism includes a servo motor and a reducer that are transmission-connected, the control end of the servo motor is signal-connected to the controller, and the power output end of the reducer is fixedly connected to the end plate.

[0023] Furthermore, it also includes a third detection unit and an alarm both connected to the controller signal, the third detection unit is fixed above the conveying channel, and the distance from the third detection unit to the second end of the conveying channel is greater than the length of the fixed support surface, and the controller is also configured to control the first power mechanism, the second power mechanism, the third power mechanism, the fourth power mechanism and the fifth power mechanism to stop and send an alarm signal to the alarm when the third detection unit continuously detects the bearing roller within time T4.

[0024] The beneficial effects of the embodiments of the present invention are:

[0025] First, the fourth power mechanism of the ejection device pushes the bearing rollers in the packaging tray onto the movable inclined platform located at the lower dead center as a whole. Since the movable inclined platform is located at the lower dead center, the bearing rollers are laterally stuck between the movable inclined platform and the fixed inclined platform on the side of the movable inclined platform close to the conveying channel. Then, the movable inclined platform is driven by the third power mechanism to rise until the lower end of the movable support surface of the movable inclined platform is higher than the upper end of the fixed support surface, so that the bearing rollers roll toward the conveying channel by the distance of the fixed inclined platform. By raising and lowering the movable inclined platform multiple times (as many times as there are rows of bearing rollers on the temporary stacking device), the bearing rollers are pushed row by row to the first end of the conveying channel.

[0026] After entering the first end of the conveying channel, the bearing rollers are driven by the first power mechanism to be conveyed to the second end of the conveying channel in a row along their axial direction, so as to be assembled to the outer ring and the inner ring for use.

[0043] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0044] See also Figures 1 to 6 The embodiment of the present invention discloses a bearing roller distributor, which includes a pushing device 400, a temporary stacking device 300 and a conveying device 100.

[0045] The conveying device includes a conveying channel 120 and a first power mechanism 110 located on one side of the conveying channel. The width of the conveying channel is slightly larger than the large end diameter of the bearing roller. Under the drive of the first power mechanism, the bearing roller moves from the first end to the second end of the conveying channel.

[0046] The temporary stacking device includes a third power mechanism 310, an equal number of at least two fixed inclined platforms 320 and a movable inclined platform 330, wherein:

[0047] The fixed ramp is located beside the second end of the conveying channel and is used to receive the bearing rollers from the second end of the conveying channel. All the fixed ramps are arranged at intervals. The fixed ramp has a fixed support surface 321 with a normal line inclined toward the direction of the conveying channel (the fixed support surface can be a flat surface or a curved surface, as long as its height can be gradually increased in the direction approaching the conveying channel). The upper end of the fixed ramp is lower than the upper surface of the conveying channel.

[0048] A movable ramp is installed on a side of each fixed ramp facing away from the conveying channel. The movable ramp has a movable support surface 331 with a normal line inclined toward the conveying channel. The movable ramp is movably arranged in a vertical direction under the drive of the third power mechanism.

[0049] The ejection device includes a fourth power mechanism 410, which is located on the side of the temporary stacking device away from the second end of the conveying channel. Driven by the fourth power mechanism, the bearing rollers in the packaging tray 700 are pushed along their own axial direction and stacked on the movable inclined platform located at the bottom dead point.

[0050] When in use, the packaging tray 700 is equipped with multiple rows of bearing rollers. The purpose of the embodiment of the present invention is to transport the multiple rows of bearing rollers in units of rows.

[0051] Specifically, the pusher first propels the bearing rollers axially. Under the action of the fourth power mechanism, each row of bearing rollers is pushed between two fixed ramps, or between a fixed ramp and a movable ramp. The third power mechanism is then activated, driving the movable ramp upward. Because the normals of the movable support surface and the fixed work surface are both oriented toward the conveying channel, all rows of bearing rollers are laterally displaced toward the conveying channel by the distance of one fixed ramp. The movable ramp then descends, ensuring that the row of bearing rollers on the movable ramp immediately adjacent to the first end of the conveying channel is transported to the first end. The first power mechanism then operates, transporting the bearing rollers, row by row, to the second end of the conveying channel.

[0052] The bearing rollers are transported in sequence and at intervals in rows through the conveying device;

[0053] After the bearing rollers on the packaging tray are pushed to the temporary stacking device under the drive of the fourth power mechanism, the third power mechanism is started, and all the movable ramps rise (in the initial state, the movable ramps are lower than the fixed ramps) until the movable support surface exceeds the height of the upper end of the fixed ramp. Under the action of the inclined surface of the movable support surface, the entire row of bearing rollers moves horizontally to the position between the next fixed ramp and the raised movable ramp. Then all the movable ramps descend and reset to prepare for the next horizontal movement. This cycle is repeated in sequence until the fixed ramps on both sides are fully stacked with bearing rollers.

[0054] Then, driven by the first power mechanism, the bearing rollers are conveyed from the first end to the second end of the conveying channel, thereby completing the conveying of the bearing rollers in rows and intervals.

[0055] In addition, a specific structure of the conveying channel is that it includes two baffles 121, the two baffles are arranged opposite to each other, and the first power mechanism is located between the two baffles.

[0056] It should be noted that the width of the conveying channel increases first and then decreases from top to bottom, and the width of both the upper and lower ends of the conveying channel is smaller than the diameter of the small end of the bearing roller. This ensures that the bearing roller is smoothly conveyed within the conveying channel while preventing it from bouncing out of the upper end of the conveying channel due to vibration or impact, thus ensuring smooth conveyance of the bearing roller.

[0057] In addition, the inner surface 1211 of the baffle is an inner cylindrical surface whose axis coincides with the axis of the bearing roller located in the conveying channel. This arrangement ensures that the gap between the bearing roller and the peripheral side is uniform, further ensuring the smooth conveying of the bearing roller.

[0058] Furthermore, the first power mechanism includes a first power unit (a servo motor may be used) 111, a driven belt roller 113, a driving belt roller 112 driven by the first power unit, and a conveyor belt 114 sleeved on the driving belt roller and the driven belt roller.

[0059] The embodiment of the present invention may further include an end-changing device 500, which includes a fifth power mechanism 510 and an end-changing plate 520 rotatable in a horizontal plane under the drive of the fifth power mechanism, and the end-changing plate is located at the second end of the conveying channel.

[0060] Bearing rollers are classified as cylindrical or tapered depending on whether their diameters are uniform along their axial direction. Cylindrical rollers have the same diameter at both ends, while tapered rollers have a large end and a small end. If all large ends were oriented in the same direction, one side of the packaging tray would be filled first, leaving the other side empty, affecting tray utilization and causing the bearing rollers to wobble within the tray. Therefore, adjacent rows of tapered rollers within the tray align their large and small ends. In other words, the large ends of adjacent rows face opposite directions on the temporary stacking device. Using an end-switch device, after one row is stacked, the next row is rotated 180°, aligning the large ends of adjacent rows. This facilitates further transport and assembly of the bearing rollers, improving tray space utilization and minimizing the gap between the bearing rollers and the tray, minimizing or eliminating wobble. (Complete filling and preventing wobble are possible when there is an even number of rows and the tray width is an integer multiple of the large and small end diameters.) Furthermore, to ensure that the packaging tray is fully stacked with bearing rollers, there must be gaps between adjacent rows of bearing rollers on the temporary stacking device. Therefore, the width of the temporary stacking device must be greater than the width of the packaging tray. Therefore, a gradually decreasing width transition tray 800 is provided between the fixed ramp and the packaging tray. The large end 810 of the transition tray is flush with the temporary stacking device, while the small end 820 of the transition tray is flush with the packaging tray. Furthermore, guide grooves 830 are provided at the bottom of the transition tray, aligning with the direction of movement of each row of bearing rollers. This prevents the bearing rollers from shifting sideways before entering the small end of the transition tray, further ensuring smooth conveyance of the bearing rollers.

[0061] In order to prevent the bearing roller 900 from rolling from both sides of the replacement end plate when the replacement end plate rotates, a concave accommodating groove 521 is formed in the middle of the replacement end plate. In order to allow the bearing roller to be smoothly pushed out of the accommodating groove, push-out chamfers 5211 are provided on both sides of the accommodating groove. Furthermore, in order to ensure that the bearing roller can smoothly move to the replacement end plate, guide edges 522 are respectively provided at both ends of the replacement end plate. The height of the guide edges gradually increases from the edge to the center. Furthermore, in order to prevent the end of the replacement end plate from interfering with the baffle when the replacement end plate rotates, a rotation avoidance chamfer 523 with a rounded structure is provided at the end of the replacement end plate.

[0062] The specific transmission and connection method of the fifth power mechanism is as follows: the working end of the cylinder 530 is fixedly connected to the connecting plate 550, and the lower end of the connecting plate is fixed to the servo motor 511. The power output end of the servo motor drives the driven gear 570 to rotate through the driving gear 560. The driven gear is coaxially fixedly connected to the rotating shaft 580, so that the rotating shaft 580 drives the grab cover below it to rotate synchronously.

[0063] The device further includes a pushing device 200, which includes a second power mechanism installed at a first end of the conveyor belt, wherein a control end of the second power mechanism is connected to the controller by signal, and the bearing roller supported on the supporting plate is pushed toward the conveyor belt under the drive of the second power mechanism;

[0064] The second power mechanism, the third power mechanism and the fourth power mechanism are all cylinders

[0065] Based on the above structure, the embodiment of the present invention can also realize automatic control. Another embodiment of the present invention can also include a controller and a first detection unit 610 and a second detection unit 620 both connected to the controller signal. The control end of the first power mechanism, the control end of the second power mechanism, the control end of the third power mechanism, the control end of the fourth power mechanism and the control end of the fifth power mechanism are all connected to the controller signal. Figure 7 ,in:

[0066] The first detection unit is fixed above the conveying channel, and the distance between the first detection unit and the first end of the conveying channel is not greater than the length of the fixed support surface. The controller is configured as follows:

[0067] When the first detection unit continuously detects the bearing roller for the first time within a time T1 (e.g., 0.5 seconds, the specific time can be set according to the formula: distance between two adjacent bearing rollers on the conveying channel / movement speed of the conveyor belt, and not less than the above ratio) in one cycle, the first power mechanism is controlled to stop, and the second power mechanism is activated to push the bearing roller on the carrying plate onto the movable inclined platform adjacent to the conveying channel;

[0068] When the first detection unit continuously detects the bearing roller for the second time or thereafter within a time T1 in a cycle, the first power mechanism is controlled to stop, and the third power mechanism, the fifth power mechanism and the second power mechanism are sequentially activated to respectively drive the movable ramp to a position where the lower end of the movable support surface exceeds the upper end of the fixed ramp, rotate the bearing roller on the carrying plate 180° and push it onto the movable ramp adjacent to the conveying channel;

[0069] When the first detection unit continuously detects no bearing roller within a time period T2 (e.g., 1 second), the first power mechanism is controlled to continue operating;

[0070] The second detection unit is fixed above the movable ramp at the maximum distance from the conveying channel, and the controller is configured to start the fourth power mechanism within a delay time T3 (3 seconds, which should be no less than the time required for the movable ramp to move from its top dead point to the bottom dead point) after the second detection unit detects the bearing roller, thereby reserving sufficient time for the movable ramp to reset and push the bearing roller on the temporary stacking device toward the packaging tray.

[0071] It should be further explained that the installation of the servo motor 511 of the fifth power mechanism and the connection between the fifth power mechanism and the end plate are as follows: the fifth power mechanism also includes a cylinder 530, and the servo motor is fixed to the power output end of the cylinder 530 through a connector to realize the lifting and lowering of the servo motor. After the servo motor is lowered, the grab cover 540 can be closely attached to the upper surface of the end plate. The grab cover has a downward opening and a receiving chamber 541 connected to the opening for accommodating the bearing roller placed on the end plate. The grab cover is the iron core of the electromagnet, and the end plate is made of ferromagnetic material. The electromagnet is energized to work, so that the end plate can be grabbed, and then the cylinder 530 pulls the servo motor, the grab cover and the end plate to rise. When the grab cover is separated from the conveyor belt, the servo motor rotates to drive the rotating shaft fixedly connected to the grab cover 540 to rotate, so that the end plate rotates 180°, the servo motor stops, and the cylinder 530 works to lower the servo motor, the grab cover and the end plate to rise. When the end plate is lowered into place (which can be set by the stroke of the cylinder 530), the electromagnet is de-energized, the grab cover is separated from the end plate, and the cylinder 530 rises to complete the reset and prepare for the next operation.

[0072] Furthermore, the second power mechanism, the third power mechanism and the fourth power mechanism are cylinder 211, cylinder 311 and cylinder 411 respectively. A push plate 212 is fixed at the end of the cylinder 211. Cylinder drive has a simple structure and sensitive response. Specifically, the second power mechanism includes a cylinder 211 arranged longitudinally in the horizontal plane (the horizontal direction is the same as the length direction of the conveying channel) and a push plate 212 fixed to the power output end of the cylinder 211. The push plate 212 pushes a sufficient number of bearing rollers for one row from the replacement end plate to the fixed ramp. The third power mechanism includes a vertically arranged cylinder 311, which drives the movable ramp up and down through the cylinder 311. The fourth power mechanism includes a cylinder 411 and a push plate 412 that can move back and forth along the length direction of the conveying channel. The push plate 412 pushes the bearing rollers stacked on the temporary stacking device to the transition plate.

[0073] Furthermore, the fifth power mechanism includes a servo motor and a reducer that are transmission-connected, the control end of the servo motor is signal-connected to the controller, and the power output end of the reducer is fixedly connected to the end plate.

[0074] Furthermore, it also includes a third detection unit and an alarm (not shown in the figure) both connected to the controller signal, the third detection unit is fixed above the conveying channel, and the distance between the third detection unit and the second end of the conveying channel is greater than the length of the fixed support surface. The controller is also configured to control the first power mechanism, the second power mechanism, the third power mechanism, the fourth power mechanism and the fifth power mechanism to stop and send an alarm signal to the alarm. The alarm is activated and sounds and lights are emitted to remind the surrounding personnel to deal with it, such as checking whether the bearing roller is stuck in the conveying channel.

[0075] It should be further explained that the conveying device, the pushing device, the temporary stacking device, the pushing device, the end-changing device, the first detection unit, the second detection unit and the third detection unit are all installed on a frame (not shown in the figure).

[0076] Finally, it should be noted that the above-mentioned first detection unit, second detection unit and third detection unit can be any one of a position switch and an ultrasonic ranging sensor. Of course, those skilled in the art will know that sensors based on other principles can also be used, which are not listed here one by one.
