Description

Technical Field

[0001] The utility model relates to the field of overturning conveyors, and more specifically, to a magnetic attraction limiting device for overturning conveyors. Background Art

[0002] In the field of intelligent warehousing, cargo transportation and turnover are achieved through conveying devices, which transport cargo outside the warehouse to the inside of the warehouse. In order to ensure the safety of cargo in the warehouse, fire doors will be installed in the warehouse. In an emergency, the fire doors will drop to separate the inside and outside of the warehouse.

[0003] Therefore, at the junction of the conveyor line and the fire door, the conveyor device needs to be set to a reversible form. In an emergency, the conveyor line will flip to make way for the descent of the fire door, ensuring that the fire door can be smoothly lowered to the lowest point.

[0004] Existing magnetic flip conveyor systems often use the suction force of an electromagnet to balance the counterweight on the other side of the flip axis. During flipping, the power is turned off to terminate the suction force, allowing the flip conveyor to flip. This solution has the following disadvantages: 1. Directly balancing the counterweight with an electromagnet requires a strong suction force, which is costly. 2. In actual use, complex operating conditions can cause significant vibration in the flip conveyor line, and the electromagnet and the magnet block cannot effectively adhere to each other, which can lead to the possibility of mis-flipping, directly affecting the normal operation of the flip conveyor line.

[0006] The technical solution of the present utility model provides a magnetic limit device for a flipping conveyor, comprising a mounting base, an electromagnet arranged on the mounting base, a supporting rocker arm rotatably connected to the mounting base, and an elastic member connected to the supporting rocker arm, the supporting rocker arm being provided with an attraction block corresponding to the electromagnet, the flipping part of the conveyor being provided with a limit shaft, the electromagnet adsorbing the attraction block when power is turned on, and the supporting rocker arm rotating to above the limit shaft.

[0007] In a preferred embodiment, a limiting block corresponding to the limiting shaft is provided at the end of the supporting rocker arm, and the limiting shaft is rotatably arranged.

[0008] In a preferred embodiment, a pin is provided on the mounting base, the support rocker arm is provided on the pin and is rotatably connected to the pin, and the connection portion between the support rocker arm and the pin is close to the limit block.

[0009] In a preferred embodiment, the elastic member includes two tension springs, and when the electromagnet is attracted to the attraction block, the tension springs are in a stretched state.

[0010] In a preferred embodiment, a limit rod is provided on the mounting base, and when the electromagnet is powered off, the tension spring pulls the supporting rocker arm to rotate until it contacts the limit rod and stops.

[0011] In a preferred embodiment, the electromagnet is adapted to the shape and size of the attraction block.

DETAILED DESCRIPTION

[0020] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and convenience of description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Numerous modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.

[0021] like Figure 1-5As shown, the technical solution of the utility model provides a magnetic limit device for a flipping conveyor, including a mounting base 6, an electromagnet 7 arranged on the mounting base 6, a supporting rocker arm 8 rotatably connected to the mounting base 6, and an elastic member connected to the supporting rocker arm 8, the supporting rocker arm 8 is provided with an attraction block 9 corresponding to the electromagnet 7, the flipping part 2 of the conveyor is provided with a limit shaft 11, when the electromagnet 7 adsorbs the attraction block 9, and the supporting rocker arm 8 rotates to above the limit shaft 11.

[0022] The magnetic limiting device 5 of this solution is arranged below the conveyor. The turning part 2 of the conveyor is connected to the fixed part 1. The turning part 2 can rotate along the turning axis 4 under the action of the gravity of the counterweight 3. The electromagnet 7 is magnetic when powered on. Through its own adsorption force, it causes the support rocker 8 to rotate until the suction block 9 is attracted to the electromagnet 7. At this time, the support rocker 8 just limits the limit shaft 11 installed on the turning part 2, so that the turning part 2 cannot turn over. In this state, the fixed part 1 and the turning part 2 are docked, and the goods can be transported. When turning over is required, the electromagnet 7 is powered off. The electromagnet 7 has no adsorption force on the suction block 9. The elastic member pulls the support rocker 8 to rotate and reset, canceling the limit on the limit shaft 11, and the turning part 2 turns over under the action of the counterweight 3. The electromagnet 7 is adapted to the shape and size of the suction block 9 to ensure the suction effect.

[0023] This solution optimizes the adsorption object of the electromagnet 7. Compared with directly adsorbing the counterweight, the required adsorption force is smaller and the cost is greatly reduced. The electromagnet 7 and the supporting rocker arm 8 are both arranged on the mounting base 6. The flipping can work normally under complex working conditions such as shaking, and accidental flipping will not occur.

[0024] The end of the support rocker 8 is provided with a stopper 10 corresponding to the stopper shaft 11, and the stopper shaft 11 is rotatably mounted. When in position, the stopper 10 is positioned above the stopper shaft 11 and in contact with the stopper shaft 11. The stopper shaft 11 can rotate to reduce friction between the stopper 10 and the stopper shaft 11 when the stopper 10 moves above the stopper shaft 11, while ensuring a close fit between the stopper 10 and the stopper shaft 11.

[0025] The mounting base 6 is provided with a pin 12, and the support swing arm 8 is provided on the pin 12 and is rotatably connected to the pin 12. The connection portion between the support swing arm 8 and the pin 12 is close to the limit block 10. The provision of the pin 12 is used to install the support swing arm 8 and ensure that the support swing arm 8 can rotate smoothly.

[0026] The elastic member includes two tension springs 13. When the electromagnet 7 is attracted to the attraction block 9, the tension springs 13 are in a stretched state. When the electromagnet 7 needs to be flipped, the adsorption force of the attraction block 9 by the electromagnet 7 disappears, and the two tension springs 13 can reset the support swing rod 8 to Figure 4 Status shown.

[0027] A limit rod 14 is provided on the mounting base 6. When the tension spring 13 is in a stretched state in the attracted state, when the electromagnet 7 is powered off, the tension spring 13 pulls the support rocker arm 8 to rotate until it contacts the limit rod 14 and stops. The limit rod 14 serves to limit the support rocker arm 8.

[0028] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making any creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in this utility model shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
