Description

Technical Field

[0001] This utility model relates to the technical field of roller positioning devices, specifically a reversible roller positioning device. Background Technology

[0002] Conveyor roller conveyors are a common conveying structure in existing technology, often used in large-scale automated logistics systems to transport, transfer, and sort boxes. During cargo transport, it may be necessary to flip the goods to facilitate quality inspection. Existing devices, such as the Chinese patent application number 202420160294.3 (a flip-up roller conveyor positioning device), allow the conveyor rollers to flip, thus turning the goods over. However, because the entire roller conveyor flips, this patent can only turn the goods 90°, making it difficult to turn them 180°. Therefore, an improved flip-up roller conveyor positioning device is needed to address this issue. Utility Model Content

[0003] The purpose of this invention is to provide a reversible roller positioning device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a reversible roller positioning device, comprising a fixed frame, with a plurality of legs uniformly fixedly arranged at the lower end of the fixed frame, a plurality of first transmission rollers uniformly and movably arranged on both sides of the inner side of the fixed frame via a rotating shaft, and a plurality of second transmission rollers uniformly and movably arranged in the middle of the inner side of the fixed frame via a rotating shaft, wherein a reversing mechanism for reversing goods is arranged between the second transmission rollers, the reversing mechanism comprising an electric push rod, a fixed frame, a rotating disk, a slot, a first servo motor, and a clamping plate, wherein an electric push rod is arranged at the lower end of the second transmission rollers, the movable end of the electric push rod is fixedly arranged with the fixed frame, the rotating disk is movably arranged on the fixed frame via a rotating shaft, a slot is opened on one side of the rotating disk, the first servo motor is fixedly arranged on one side of the upper end of the rotating disk, and a clamping plate is fixedly arranged on the movable end of the first servo motor.

[0005] Preferably, a second servo motor is fixedly installed on one side of the fixed frame surface. The power output shaft of the second servo motor is connected to the rotating shaft of the rotating disk, and the rotating disk can be driven to rotate by the second servo motor.

[0006] Preferably, a first pulley is fixedly provided at one end of each of the first and second transmission rollers. A first belt is fitted on the surface of the first pulley. The first and second pulleys can link all the first and second transmission rollers together, thereby ensuring that all the first and second transmission rollers can rotate synchronously for transmission.

[0007] Preferably, the second transfer roller has a notch in the middle, which allows space for the installation of the flipping mechanism.

[0008] Preferably, a second pulley is fixedly provided at the end of the second transmission roller away from the first pulley, and a second belt is sleeved between the second pulleys. The second transmission rollers can be linked together by the second pulleys and the second belt. Since the second transmission roller of this device is disconnected in the middle with a notch, in order to ensure that the separated second transmission rollers can transmit synchronously, it is necessary to use the second pulleys and the second belt for power transmission.

[0009] Preferably, a speed reducer is fixedly installed on both sides of the fixed frame surface, and a drive motor is fixedly installed at the lower end of the speed reducer. The power output shaft of the drive motor is connected to the power input shaft of the speed reducer, and the power output shaft of the speed reducer is connected to the rotating shaft where the first transmission roller is located. The drive motor and the speed reducer can drive the first transmission roller and the second transmission roller of the whole device to rotate and transmit.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention can flip the transported material at multiple angles, including 90-degree and 180-degree flips, which facilitates subsequent inspection or labeling work.

[0012] This invention allows the second transmission roller to be separated through a notch, which facilitates the installation of the flipping mechanism within the device. This is equivalent to installing the flipping mechanism on one side of the fixed frame, inside the fixed frame, reducing the space occupied by the device and making it easier to assemble and place.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a flip-up roller positioning device, including a fixed frame 5, with a plurality of legs evenly fixedly arranged at the lower end of the fixed frame 5, a plurality of first transmission rollers 2 evenly and movably arranged on both sides of the inside of the fixed frame 5 via a rotating shaft, and a plurality of second transmission rollers 3 evenly and movably arranged in the middle of the inner side of the fixed frame 5 via a rotating shaft, and a flipping mechanism for flipping goods is arranged between the second transmission rollers 3, the flipping mechanism including an electric push rod 4, a fixed frame 5, a rotating disk 6, a slot 7, a first servo motor 8, and a clamping plate 9, the electric push rod 4 is arranged at the lower end of the second transmission rollers 3, the fixed frame 5 is fixedly arranged at the movable end of the electric push rod 4, the rotating disk 6 is movably arranged on the fixed frame 5 via a rotating shaft, the slot 7 is opened on one side of the rotating disk 6, the first servo motor 8 is fixedly arranged on one side of the upper end of the rotating disk 6, and the clamping plate 9 is fixedly arranged at the movable end of the first servo motor 8.

[0020] A second servo motor 10 is fixedly installed on one side of the surface of the fixed frame 5. The power output shaft of the second servo motor 10 is connected to the rotating shaft of the rotating disk 6. The second servo motor 10 can drive the rotating disk 6 to rotate.

[0021] The first transmission roller 2 and the second transmission roller 3 are each fixedly provided with a first pulley 11 at one end. The surface of the first pulley 11 is fitted with a first belt 12. The first pulley 11 and the second pulley 13 can link all the first transmission rollers 2 and the second transmission rollers 3 together, thereby ensuring that all the first transmission rollers 2 and the second transmission rollers 3 can rotate synchronously to perform transmission work.

[0022] The second transmission roller 3 has a notch 15 in the middle, which allows the second transmission roller 3 to be separated, thus providing space for the installation of the flipping mechanism in this device; it is equivalent to installing the flipping mechanism on one side of the fixed frame 5, which reduces the space occupied by this device by installing it inside the fixed frame 5, thereby making it easier to build and place this device.

[0023] The second transmission roller 3 is fixedly provided with a second pulley 13 at the end away from the first pulley 11. A second belt 14 is sleeved between the second pulleys 13. The second transmission roller 3 can be linked together by the second pulleys 13 and the second belt 14. Since the second transmission roller 3 of this device is broken in the middle with a notch 15, in order to ensure that the separated second transmission rollers 3 can be transmitted synchronously, it is necessary to use the second pulleys 13 and the second belt 14 for power transmission.

[0024] A speed reducer 16 is fixedly installed on both sides of the surface of the fixed frame 5. A drive motor 17 is fixedly installed at the lower end of the speed reducer 16. The power output shaft of the drive motor 17 is connected to the power input shaft of the speed reducer 16. The power output shaft of the speed reducer 16 is connected to the rotating shaft where the first transmission roller 2 is located. The first transmission roller 2 and the second transmission roller 3 of the whole device can be driven to rotate and transmit through the drive motor 17 and the speed reducer 16.

[0025] Working Principle: This device uses the first transmission roller 2 to transport goods towards the flipping mechanism, ultimately allowing the goods to engage in the locking space formed by the clamping plate 9 and the slot 7 of the rotating disk 6. The goods can then be flipped. To achieve this, the first electric push rod 4 extends to provide space for the goods to flip, and then the second servo motor 10 drives the rotating disk 6 to rotate. The rotation stops when the target angle of 90 or 180 degrees is reached. The second electric push rod 4 then retracts to bring the goods into contact with the surface of the second transmission roller 3. At this point, the first servo motor 8 drives the clamping plate 9 to rotate, causing it to misalign with the goods. The goods are no longer clamped or obstructed, and the second transmission roller 3 allows for continued transport. This device can flip transported materials at multiple angles, including 90-degree and 180-degree flips, facilitating subsequent inspection or labeling.
