Description

Technical Field

[0001] The invention relates to a turntable type power roller and a docking device. Background Art

[0002] In recent years, with the rapid development of my country's new energy battery industry, powder equipment has further room for growth. At the same time, it faces the severe challenge of meeting the requirements of rational resource utilization, energy conservation and consumption reduction, and environmental protection. While pursuing economies of scale and product diversification, powder equipment must also develop towards automatic control and mechatronics.

[0003] To address the efficiency and accuracy issues of powder conveying during lithium battery production, the use of mobile containers for powder conveying is becoming increasingly popular. During the mobile container conveying process, due to the crisscrossing of conveyor lines, a powered turntable is required to connect the conveyor lines. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention provides a turntable power roller and docking device, which allows the mobile container to change its angle on the conveyor line, realizing the rotational docking of mobile containers with large load materials, and the rotational docking is stable and reliable.

[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: a turntable-type power roller and docking device, including a PLC controller, a rotating mechanism, a moving mechanism, a sensing mechanism and a limiting mechanism. The moving mechanism is installed on the upper side of the rotating mechanism. The moving mechanism is used to transport the mobile container. The sensing mechanism is installed on one side of the mobile mechanism and is used to sense the mobile container. The limiting mechanism is installed between the mobile mechanisms. The mobile container body is limited by the limiting mechanism, so that the rotating mechanism drives the mobile mechanism to rotate.

[0006] Preferably: the rotating mechanism includes a turntable reduction motor, a rotating base, a turntable bearing, a slewing bracket and a drum chassis. The turntable reduction motor is fixed to the rotating base through a motor mounting plate. The bottom of the slewing bracket is connected to the rotating base through a turntable bearing. The outer ring of the turntable bearing is provided with external teeth. The turntable reduction motor is connected to a driving gear. The turntable reduction motor drives the driving gear to engage with the external teeth, thereby driving the slewing bracket to rotate. The drum chassis is fixed on the upper side of the slewing bracket. The turntable reduction motor can adopt a turbine worm reduction motor.

[0007] Preferably, two impact bars and two angle sensors are sequentially installed on the four sides of the rotating base. The two impact bars are installed on two adjacent sides of the rotating base, and the two angle sensors are installed on the other two adjacent sides of the rotating base. A limit block and a detection block are installed on the slewing bracket. The limit block and the detection block are on opposite sides of each other. When the limit block and the detection block of the slewing bracket rotate back and forth, the limit block contacts the two impact bars respectively, and the detection block senses the two angle sensors respectively. The angle sensor sends a signal to the PLC controller, thereby controlling the turntable reduction motor to stop rotating, and the limit block prevents further rotation through contact with the impact bars, thereby limiting the rotation angle range of the slewing bracket. The angle sensor is used to control the rotation angle and simultaneously control the start and stop of the turntable reduction motor to ensure more accurate docking. The impact bar is used for limiting and preventing excessive rotation.

[0008] The preferred moving mechanism includes a conveyor base, a drive motor, and several rollers. The conveyor base is mounted on the upper side of the roller base frame, with baffles installed on both sides of the conveyor base. Rollers are installed between the baffles. Each roller has a gear at one end, and adjacent gears are connected by a chain. The drive motor is connected to one of the rollers via a chain. The drive motor uses a servo motor, which can drive the rollers in both forward and reverse directions, thereby driving the rollers to rotate forward and reverse, making it convenient for the container to move in any direction.

[0009] Preferably, the limiting mechanism includes a first buffer limiter, a first hard limiter, a second buffer limiter, and a second hard limiter. The first buffer limiter and the first hard limiter are located on one side of the drum chassis, while the second buffer limiter and the second hard limiter are located on the other side of the drum chassis. The first buffer limiter and the second buffer limiter have the same structure, and the first hard limiter and the second hard limiter have the same structure. The first hard limiter and the second hard limiter can be used to position the mobile container between them. After the drum chassis completes rotation, it is released to connect to the next conveyor line.

[0010] Preferably, the first buffer limiter includes a first base plate, a first mounting block, a first cylinder, a first lifting block, and a hydraulic buffer. The first mounting block is connected to the upper side of the first base plate. The first cylinder is fixed to the inner bottom of the first mounting block. The upper side of the first mounting block is movably engaged with the first lifting block. The first cylinder drives the first lifting block to move up and down. The hydraulic buffer is mounted on the first lifting block. The hydraulic buffer can cushion the movement of the container and absorb the impact of the moving container. It can be retracted when not in use.

[0011] Preferably, the second hard stopper includes a second base plate, a second mounting block, a second cylinder, a second lifting block, an adjustable screw, and a bumper. The second mounting block is connected to the upper side of the second base plate. The second cylinder is fixed to the inner bottom of the second mounting block. The upper side of the second mounting block movably cooperates with the second lifting block. The second cylinder drives the second lifting block to move upward and downward. The second lifting block is mounted with an adjustable screw, one end of which is fixed to the bumper. The bumper can directly stop the moving container.

[0012] Preferably: the sensing mechanism includes a first photoelectric sensor, a second photoelectric sensor, a third photoelectric sensor, and a fourth photoelectric sensor. The first photoelectric sensor and the second photoelectric sensor are used as a pair, and the third photoelectric sensor and the fourth photoelectric sensor are used as another pair, so that the mobile container can be used through the corresponding pair of sensors regardless of whether it moves forward or backward. All sensors are connected to the PLC controller. For example, when the first photoelectric sensor senses the approach of the mobile container, it sends a signal to the PLC controller, thereby controlling the drive motor to slow down. When the second photoelectric sensor continues to detect the mobile container, the PLC controller controls the drive motor to stop. Setting two pairs of sensors can make the mobile container be used through the corresponding pair of sensors regardless of whether it moves forward or backward.

[0013] Preferably, bull's eye bearings are provided on all four sides of the upper side of the drum chassis.

[0014] Preferably, the drum chassis is provided with brackets at both ends of the drum, and the brackets are provided with non-powered rollers. The bull's eye bearing and the non-powered rollers serve as transition devices for moving the container from the previous drum line to the turntable.

[0015] The present invention has the beneficial effects of:

[0016] The driving motor can drive the roller to rotate forward and backward, which is convenient for the mobile container to move back and forth. The sensing mechanism is used to sense whether the mobile container is approaching, and the signal is sent to the PLC controller. The PLC controller controls the driving motor to slow down or stop, and the mobile container is roughly positioned on both sides through the limit mechanism to prevent the mobile container from slipping during rotation. Finally, the rotating mechanism drives the roller chassis on the rotary bracket to rotate together. The rotation angle is detected and controlled by the angle sensor, and then the turntable reduction motor is controlled by the PLC controller to slow down and stop. After the rotation is completed, the limit mechanism drops, and the mobile container can be moved to the next conveyor line. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The preferred embodiments of the present invention are further described in detail with reference to the accompanying drawings.

[0028] like Figure 1-9The described turntable power roller and docking device includes a PLC controller, a rotating mechanism 1, a moving mechanism 2, a sensing mechanism 3 and a limiting mechanism. The moving mechanism 2 is installed on the upper side of the rotating mechanism 1. The rotating mechanism 1 includes a turntable reduction motor 11, a rotating base 12, a turntable bearing 13, a slewing bracket 14 and a roller base frame 15. The turntable reduction motor 11 is fixed to the rotating base 12 through a motor mounting plate. The bottom of the slewing bracket 14 is connected to the rotating base 12 through a turntable bearing 13. The outer ring of the turntable bearing 13 is provided with an external tooth 20. The turntable bearing 13 and the external tooth 20 are a whole. A driving gear is connected to the turntable reduction motor 11. The turntable reduction motor 11 drives the driving gear to engage with the external tooth 20, thereby driving the slewing bracket 14 to rotate. The roller base frame 15 is fixed on the upper side of the slewing bracket 14. The turntable reduction motor 11 can adopt a turbine worm reduction motor.

[0029] Two collision bars 16 and two angle sensors 17 are sequentially installed on the four sides of the rotating base 12. The two collision bars 16 are installed on two adjacent sides of the rotating base 12, and the two angle sensors 17 are installed on the other two adjacent sides of the rotating base 12. A limit block 18 and a detection block 19 are installed on the slewing bracket 14. The limit block 18 and the detection block 19 are on opposite sides of each other. When the limit block 18 and the detection block 19 of the slewing bracket 14 rotate back and forth, the limit block 18 contacts the two collision bars 16 respectively, and the detection block 19 senses the two angle sensors 17 respectively. In this embodiment, when the detection block 19 rotates 90 degrees with the slewing bracket 14, it senses one of the angle sensors 17, and the angle sensor 17 can send a signal to the PLC controller, thereby controlling the turntable reduction motor 11 to stop rotating, and the limit block 18 prevents further rotation by contacting the collision bar 16, thereby limiting the rotation angle range of the slewing bracket 14. The angle sensor 17 is used to control the rotation angle and control the start and stop of the turntable reduction motor 11 to ensure more accurate docking. The collision bar 16 is used for limiting and preventing excessive rotation.

[0030] The moving mechanism 2 is used to transport the mobile container and includes a conveyor base 21, a drive motor 22, and several rollers 23. The conveyor base 21 is mounted on the upper side of the roller base 15. Baffles 24 are installed on both sides of the conveyor base 21. The rollers 23 are installed between the baffles 24. Each roller 23 has a gear at one end, and adjacent gears are connected by a chain. The drive motor 22 is connected to one of the rollers 23 via a chain. The drive motor 22 is a servo motor that can drive the rollers 23 in both directions, thereby driving the rollers 23 to rotate forward and backward, facilitating the movement of the mobile container in any direction.

[0031] The sensing mechanism 3 is installed on one side of the mobile mechanism 2 and is used to sense the mobile container. The sensing mechanism includes a first photoelectric sensor 31, a second photoelectric sensor 32, a third photoelectric sensor 33 and a fourth photoelectric sensor 34. The first photoelectric sensor 31 and the second photoelectric sensor 32 are used as a pair, and the third photoelectric sensor 33 and the fourth photoelectric sensor 34 are used as another pair, so that the mobile container can be used through the corresponding pair of sensors regardless of whether it moves forward or backward. All sensors are connected to the PLC controller. For example, when the first photoelectric sensor 31 senses the approach of the mobile container, it sends a signal to the PLC controller, thereby controlling the drive motor 22 to decelerate. When the second photoelectric sensor 32 continues to detect the mobile container, the PLC controller controls the drive motor 22 to stop. Setting two pairs of sensors allows the mobile container to be used through the corresponding pair of sensors regardless of whether it moves forward or backward.

[0032] The limiting mechanism is installed between the moving mechanism 2, limiting the mobile container body through the limiting mechanism, so that the rotating mechanism 1 drives the moving mechanism 2 to rotate. The limiting mechanism includes a first buffer limiter 4, a first hard limiter 5, a second buffer limiter 6, and a second hard limiter 7. The first buffer limiter 4 and the first hard limiter 5 are located on one side of the drum chassis 15, and the second buffer limiter 6 and the second hard limiter 7 are located on the other side of the drum chassis 15. The first buffer limiter 4 and the second buffer limiter 6 have the same structure, and the first hard limiter 5 and the second hard limiter 7 have the same structure. The first hard limiter 5 and the second hard limiter 7 can be used to position the mobile container between them. After the drum chassis 15 completes its rotation, it is released and docked with the next conveyor line.

[0033] The first buffer limiter 4 includes a first base plate 41, a first mounting block 42, a first cylinder 43, a first lifting block 44, and a hydraulic buffer 45. The first mounting block 42 is connected to the upper side of the first base plate 41. The first cylinder 43 is fixed to the bottom of the first mounting block 42. The upper side of the first mounting block 42 is movably engaged with the first lifting block 44. The first cylinder 43 drives the first lifting block 44 to move up and down. The hydraulic buffer 45 is installed on the first lifting block 44. The hydraulic buffer 45 can cushion the impact of the moving container during movement and can be retracted when not in use.

[0034] The second hard limiter 7 includes a second base plate 71, a second mounting block 72, a second cylinder, a second lifting block 74, an adjustable screw 75, and a bumper 76. The second mounting block 72 is connected to the upper side of the second base plate 71. The second cylinder is fixed to the inner bottom of the second mounting block 72. The upper side of the second mounting block 72 is movably engaged with the second lifting block 74. The second cylinder drives the second lifting block 74 to move up and down. The adjustable screw 75 is installed on the second lifting block 74, and one end of the adjustable screw 75 is fixed to the bumper 76. The bumper 76 can directly stop the mobile container.

[0035] Bull's eye bearings 8 are provided around the upper side of the drum chassis 15. Brackets 91 are provided on the drum chassis 15 at the front and rear ends of the drum 23, and unpowered rollers 92 are provided on the brackets 91. The bull's eye bearings 8 and unpowered rollers 92 serve as a transition device for moving the container from the upper drum 23 line to the turntable.

[0036] During actual operation, the driving motor 22 can drive the roller 23 to rotate forward and backward. When the first photoelectric sensor 31 senses the approach of the mobile container, it sends a signal to the PLC controller, thereby controlling the driving motor 22 to decelerate, and at the same time controlling the second buffer limiter 6 and the second hard limiter 7 to lift up. When the second photoelectric sensor 32 continues to detect the mobile container, the PLC controller controls the driving motor 22 to stop. After the roller 23 stops, due to the effect of inertia, the mobile container will not stop immediately, but will continue to run to the second buffer limiter 6. Under the action of the buffer, the impact of the mobile container will be absorbed until the mobile container hits the second hard limiter 7, and the mobile container stops; after the mobile container stops, the first buffer limiter 4 and the first hard limiter 5 are raised, and the mobile container is roughly positioned between the two hard limiters. At this point, the rough positioning of the mobile container is completed to prevent the mobile container from slipping during rotation. Finally, the turntable reduction motor 11 drives the driving gear to rotate, and the gear rotates and engages with the external teeth, thereby driving the slewing bracket 14 to rotate, and at the same time driving the roller chassis 15 to rotate. When one of the angle sensors 17 senses the detection block 19, it sends a signal to the PLC controller. The PLC controller controls the turntable reduction motor 11 to slow down and stop rotating, and the limit block 18 contacts the impact bar 16 to prevent inertia from continuing to rotate. After the rotation is completed, the limit mechanism drops, and the mobile container can be moved to the next conveyor line.

[0037] The above embodiments are only used to illustrate the inventive concept of the present invention, and are not intended to limit the protection of the rights of the present invention. Any non-substantial changes to the present invention using this concept should fall within the scope of protection of the present invention.
