Description

TECHNICAL FIELD

[0001] The utility model relates to automatic equipment technical field especially relates to a kind of circulating conveying device based on magnetic suspension. BACKGROUND

[0002] Compared with traditional synchronous belt or chain conveying line, the magnetic suspension conveying line has the advantages of high transmission efficiency, small wear, low energy consumption, small noise, flexible adjustment (the spacing and material position between materials can be adjusted in real time according to needs), accurate positioning and strong load capacity, and is more and more applied to automatic production line. However, when the magnetic suspension carrier or magnetic suspension trolley circulates in the horizontal direction or vertical direction, horizontal transverse switching or up-down switching is often required. For vertical circulation conveying, the traditional switching mode drives the carrier or magnetic suspension trolley from the upper layer to the lower layer through the up-down lifting mechanism. The up-down lifting mechanism is a conventional servo-screw driven mode. Although this mode has a simple structure, the switching speed is slow. When the carrier or magnetic suspension trolley runs to the lower layer, the carrier or magnetic suspension trolley in the upper layer is in a waiting state, and vice versa. This leads to discontinuous conveying and seriously affects the production capacity of the production line, making it difficult to meet the needs of modern automated production lines with rapid development.

Detailed Implementation

[0021] A magnetically levitated circular conveying device, such as Figures 1 to 5 As shown, the system includes a magnetic levitation transport section 1 and a flipping section 2. Two flipping sections 2 are respectively located at both ends of the magnetic levitation transport section 1. The magnetic levitation transport section 1 includes a first frame 3 and an upper magnetic levitation transport mechanism 4 and a lower magnetic levitation transport mechanism 5 respectively disposed opposite to each other at the top and bottom of the first frame 3. The first track 41 of the upper magnetic levitation transport mechanism 4 faces upward, and the second track 51 of the lower magnetic levitation transport mechanism 5 faces downward. The flipping section 2 includes a second frame 6 and two sets of flipping section magnetic levitation mechanisms 7 and a flipping mechanism 8 disposed on the second frame 6. The two sets of flipping section magnetic levitation mechanisms 7 are connected relative to each other and then connected to the flipping mechanism 8. The third track 71 on the levitation mechanism 7 faces opposite directions. The flipping mechanism 8 drives the two sets of flipping section magnetic levitation mechanisms 7 to rotate 180 degrees simultaneously, so that the third track 71 on the two sets of flipping section magnetic levitation mechanisms 7 alternately connects with the first track 41 of the upper magnetic levitation conveyor 4 and the second track 51 of the lower magnetic levitation conveyor 5, so as to realize the magnetic levitation trolley 10 circulating on the upper magnetic levitation conveyor 4 and the lower magnetic levitation conveyor 5. The magnetic levitation trolley 10 is used to load and transport materials, and can run along the first track 41 of the upper magnetic levitation conveyor 4, the third track 71 on the flipping section magnetic levitation mechanism 7, and the second track 51 of the lower magnetic levitation conveyor 5 under the action of magnetic levitation. In this way, the entire conveying device can be similar to a belt conveyor or chain conveyor to circulate and transport the magnetic levitation trolley, and the magnetic levitation trolley flows on the conveyor line to transfer materials.

[0022] The function of the flipping mechanism 8 is to drive the two sets of flipping segment magnetic levitation mechanisms 7 to flip. It can be an existing structure that can achieve rotation. As one embodiment, in this embodiment, the flipping mechanism 8 includes a flipping motor 81 and a rotating shaft 82. The flipping mechanism 8 is mounted on the second mounting frame. The rotating shaft 82 is rotatably mounted on the second frame 6 through bearings. The two sets of flipping segment magnetic levitation mechanisms 7 are fixedly connected to the rotating shaft 82. The flipping motor 81 is driven by the rotating shaft 82. It drives the two sets of flipping segment magnetic levitation mechanisms 7 to rotate 180 degrees in the forward direction to complete the docking and transfer of the magnetic levitation trolley 10. Then, it rotates 180 degrees in the reverse direction. This facilitates the wiring and avoids tangling.

[0023] Because cables are connected to the magnetic levitation mechanism, to further prevent the cables from getting tangled due to rotation, in this embodiment, as follows... Figure 6 The second frame 6 is provided with a cable guide groove 11, which is located at one end near the flipping motor 81 and forms a semi-circular shape around the rotation shaft 82, with the axis of the rotation shaft 82 as the center of the semi-circle. A cable guide tube 9 is also provided for cable routing. One end of the cable guide tube 9 is connected to the magnetic levitation mechanism 7 of the flipping section, and the other end passes through the cable guide groove 11. All cables are concentrated in the cable guide tube 9 and move along the semi-circular cable guide groove 11 with the cable guide tube 9, eliminating the need for a slip ring, making cable routing convenient, neat, and easy to maintain.

[0024] To ensure the accuracy of the rotation angle, in this embodiment, as follows: Figure 4 An encoder 12 is also provided at one end of the rotating shaft 82. The encoder 12 is used to detect the rotation angle in real time so as to correct the rotation angle at any time, ensuring that the third track 71 of the flipping section magnetic levitation mechanism 7 can be smoothly connected with the first track 41 of the upper magnetic levitation conveying mechanism 4 and the second track 51 of the lower magnetic levitation conveying mechanism 5, so as to avoid the magnetic levitation car 10 deviating from the track and colliding.

[0025] In this embodiment, a position sensor 13 is also provided on the second frame 6. The position sensor 13 is used to detect the position of the flip section magnetic levitation mechanism 7 to ensure the positive and negative directions of rotation.

[0026] The flip section magnetic levitation mechanism 7 includes a flip section magnetic levitation motor (not shown in the figure). The flip section magnetic levitation motor is used to provide magnetic levitation motion power for the magnetic levitation vehicle 10, so that it can travel on the third track 71 of the flip section magnetic levitation mechanism 7 to enter or exit the flip section 2. At the same time, when the flip section magnetic levitation mechanism 7 flips, it is used to lock the magnetic levitation vehicle 10.

[0027] The working process of this utility model is as follows: When the magnetic levitation vehicle 10 runs from the upper magnetic levitation conveying mechanism 4 to the flipping section 2 under magnetic levitation drive, the magnetic levitation motor of the flipping section locks the magnetic levitation vehicle 10. The flipping motor 81 drives the magnetic levitation mechanism 7 of the flipping section to rotate 180 degrees. After rotating to the position, the magnetic levitation motor of the flipping section releases the magnetic levitation vehicle 10 and provides power to the magnetic levitation vehicle 10 so that it drives out of the flipping section 2 and arrives at the lower magnetic levitation conveying mechanism 5. The flipping motor 81 then drives the magnetic levitation mechanism 7 of the flipping section to rotate 180 degrees in the opposite direction. In this way, a complete cycle is formed. The magnetic levitation vehicle 10 transitions from the upper magnetic levitation conveying mechanism 4 to the lower magnetic levitation conveying mechanism 5 through the flipping section 2, thereby realizing the cyclic conveying.

[0028] The above detailed description is directed to the specific implementation of the feasible embodiments of the present application, and the embodiments are not used to limit the patent range of the present application. Any equivalent implementation or change without departing from the present application shall be included in the patent range of the present application.
