At this time, a horizontal conveying device is docked at the upstream, and an inclined conveying device is docked at the downstream. Therefore, a new mechanism is urgently needed between the horizontal upstream and the inclined downstream to realize the transportation of the tray. Summary of the Utility Model

[0003] In order to solve the above problems of the prior art, the utility model provides a turnover mechanism, which can realize the transportation of the tray between the horizontal upstream and the inclined downstream.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] In a first aspect, the utility model provides a turnover mechanism, which includes a lifting cylinder, a conveying component and a fixed turning shaft.

[0007] The beneficial effect of the utility model is that: the lifting cylinder and the fixed turning shaft drive the conveying component to rotate to dock the horizontal upstream and the inclined downstream. The driving mechanism drives the driving rollers to rotate, so that the tray can enter and exit the feeding channel formed by the driving rollers and the pressing rollers, thereby realizing the transportation of the tray between the horizontal upstream and the inclined downstream. At the same time, the pressing rollers limit the tray to prevent the tray from falling out of the conveying component during the turnover process, ensuring the safety of the tray transportation.

[0008] Optionally, a plurality of auxiliary rollers are distributed at intervals on one side of the conveying component at the bottom when it is inclined. The driving mechanism drives each of the auxiliary rollers to rotate. The auxiliary rollers are perpendicular to the driving rollers and are located on the feeding channel.

[0009] According to the above description, the auxiliary rollers are used to assist the tray to be transported to the downstream when it is inclined.

[0010] Optionally, the driving mechanism includes a motor, a driving gear, a transmission gear, a first magnetic ring, a second magnetic ring, and a third magnetic ring. The output shaft of the motor is connected to the driving gear, the driving gear meshes with the transmission gear, and the transmission gear and a plurality of first magnetic rings are fixed on a rotating shaft;

[0012] Optionally, a buffer is further included. Two buffers are respectively provided at the starting position and the ending position of the rotation of the conveying assembly, and their buffer ends are in vertical contact with the conveying assembly.

[0013] According to the above description, it can be seen that the buffer is used to absorb and reduce the impact force and vibration generated during the flipping process, and improve the stability of the tray flipping.

[0034] In order to better understand the above technical solutions, the exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more clear and thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0035] Embodiment 1

[0036] Please refer to Figures 1 to 4 , a flipping mechanism, including a lifting cylinder 1, a conveying component 2 and a fixed rotating shaft 3. The driving shaft 11 of the lifting cylinder 1 is rotatably connected to one side of the conveying component 2, and the other side of the conveying component 2 is rotatably connected to the fixed rotating shaft 3. One end of the lifting cylinder 1 far from the driving shaft 11 is rotatably connected to a fixed seat 6.

[0037] As Figure 1 shown, in this embodiment, the driving shaft 11 of the lifting cylinder 1 and the conveying component 2, as well as the lifting cylinder 1 and the fixed seat 6, are both rotatably connected through a double-ear angle seat.

[0038] As Figure 3 and 4 shown, the conveying component 2 includes a conveying bracket 21 and a driving mechanism 22, a plurality of driving rollers 23 spaced apart, a plurality of pressure rollers 24 spaced apart, and a plurality of auxiliary rollers 26 spaced apart on one side at the bottom when tilted, arranged on the conveying bracket 21. The driving mechanism 22 is connected to the driving rollers 23. The first plane formed by the plurality of pressure rollers 24 is parallel to and above the second plane formed by the plurality of driving rollers 23, and there is a feeding channel 25 for the feeding tray to enter between them. The auxiliary rollers 26 are perpendicular to the driving rollers 23 and are located on the feeding channel 5. Among them, in this embodiment, the side at the bottom when tilted is the side opposite to the side where the driving motor 221, the driving gear 222, the transmission gear 223, the first magnetic ring 224, and the second magnetic ring 225 are located.

[0039] In this embodiment, the driving mechanism 22 includes a motor 221, a driving gear 222, a transmission gear 223, a first magnetic ring 224, a second magnetic ring 225, and a third magnetic ring 226. The output shaft of the motor 221 is connected to the driving gear 222. The driving gear 222 meshes with the transmission gear 223. The transmission gear 223 and a plurality of first magnetic rings 224 are fixed on a rotating shaft. Second magnetic rings 225 are provided at both ends of each driving roller 23. The second magnetic rings 225 on the first end of the driving roller 23 correspond to the first magnetic rings 224 one by one, and they are in a corresponding relationship in terms of quantity and position. A third magnetic ring 226 is provided on each auxiliary roller 26, and each third magnetic ring 226 corresponds to a second magnetic ring 225 on the second end of a driving roller 23. In this embodiment, the number of auxiliary rollers 26 is less than that of the driving rollers 23. Therefore, the number of corresponding third magnetic rings 226 is less than that of the second magnetic rings 225 on the second ends of the driving rollers 23. At this time, each pair of the first magnetic ring 224 and the second magnetic ring 225, and each pair of the second magnetic ring 225 and the third magnetic ring 226 are in orthogonal transmission, so as to realize the motor 221 driving the driving rollers 23 and the auxiliary rollers 26 to rotate around mutually perpendicular axes.

[0040] In this embodiment, both the driving roller 23 and the auxiliary roller 26 are rubber-coated wheels in the shape of long cylinders, the pressing roller 24 is a hollow shaft, and the diameter of the pressing roller 24 is smaller than that of the driving roller 23. Specifically, the outer diameters of the driving roller 23 and the auxiliary roller 26 are 30 mm, and the outer diameter of the pressing roller 24 is 15 mm.

[0041] When this embodiment is applied to an actual scenario, the inclination angle of the conveying assembly 2 is 75°. In other embodiments, it can be inclination angles from 0 to 90° such as 60°, 45°, 30°, etc.

[0042] Thus, the working principle of this embodiment is as follows:

[0043] Start the device. The upstream sends the tray to the feeding channel 25, and the motor 221 drives the driving roller 23 and the auxiliary roller 26 to rotate, so that the tray enters the feeding channel 25;

[0044] The lifting cylinder 1 lifts the conveying assembly 2 to start tilting, and the pressing roller 24 limits the tray to prevent the tray from falling out of the conveying assembly 2 during the flipping process;

[0045] When it reaches the inclined state of 75°, the motor 221 drives the driving roller 23 and the auxiliary roller 26 to rotate. At this time, the tray contacts the auxiliary roller 26 under the action of gravity. Therefore, the auxiliary roller 26 rotates to assist in conveying the tray to the downstream until the tray completely exits the feeding channel 25;

[0046] The lifting cylinder 1 retracts to drive the conveying assembly 2 back to the horizontal position, and starts to convey the next tray. Thus, it circulates continuously to complete the continuous conveying of the trays.

[0047] Embodiment Two

[0048] Please refer to Figures 1 to 4 , a flipping mechanism. On the basis of Embodiment One, this embodiment further includes buffers. Two buffers are respectively arranged at the starting position and the ending position of the rotation of the conveying assembly 2, and their buffer ends are in vertical contact with the conveying assembly 2.

[0049] As Figure 2 shown, the buffers include a horizontal buffer 4 and an inclined buffer 5. The horizontal buffer 4 is arranged at the starting position of the rotation, and the inclined buffer 5 is arranged at the ending position of the rotation. The buffer can be a hydraulic buffer such as an oil pressure buffer, or an elastic buffer such as a spring. Its main function is to absorb and reduce the impact force and vibration generated during the flipping process through the buffer, and improve the stability of the tray flipping.

[0050] Embodiment Three

[0051] Please refer to Figures 1 to 4, a flipping mechanism. In this embodiment, based on Embodiment 1, the conveying assembly 2 is provided with a height adjustment mechanism on each pressure roller 24. The height adjustment mechanism includes a locking accessory and a height adjustment block 27. One height adjustment block 27 is provided at each end of the pressure roller 24. The height adjustment block 27 is provided with a long through hole, and the length direction of the long through hole is perpendicular to the distribution direction of the pressure rollers 24. The locking accessory passes through the long through hole and is detachably connected to the conveying bracket 21. Thereby driving the pressure roller 24 to approach or move away from the driving roller 23, thus adjusting the height of the feeding channel 25 to adapt to trays of different heights.

[0052] Among them, the locking accessory can be a screw. The screw end of the screw passes through the long through hole and is threadedly connected to the threaded hole on the conveying bracket 21 to achieve detachable connection, and the nut is fixed above the long through hole to achieve locking.

[0053] Embodiment 4

[0054] Please refer to Figures 1 to 4 , a flipping mechanism. In this embodiment, based on Embodiment 1, the conveying assembly 2 is provided with a lifting and blocking mechanism 28 on the outlet side of the feeding channel 25. The lifting and blocking mechanism 28 includes a lifting cylinder 281 and a blocking member 282. The lifting cylinder 281 is fixed on the conveying bracket 21, and the lifting end of the lifting cylinder 281 is connected to the blocking member 282. The lifting cylinder 281 drives the blocking member 282 to enter and exit the outlet side of the feeding channel 25, so as to block the tray from falling out of the feeding channel 25 when feeding.

[0055] Therefore, on the basis of the above Embodiment 1, combined with Embodiments 2 to 4, its overall working principle is further described as follows:

[0056] Before the equipment is started, first adjust the height of the pressure roller 24 according to the thickness of the tray until the height of the feeding channel 25 conforms to the thickness of the tray;

[0057] After that, start the equipment. The blocking member 282 is located on the outlet side of the feeding channel 25. The upstream sends the tray to the feeding channel 25, and the motor 221 drives the driving roller 23 and the auxiliary roller 26 to rotate, so that the tray enters the feeding channel 25 until the tray contacts the blocking member 282;

[0058] The lifting cylinder 1 lifts the conveying assembly 2 to start tilting. The pressure roller 24 limits the tray to prevent the tray from falling out of the conveying assembly 2 during the flipping process, and the tilting buffer 5 buffers the impact force at the moment of reaching the position;

[0059] When reaching the inclined state of 75°, the lifting cylinder 281 drives the blocking member 282 to descend, and the motor 221 drives the driving roller 23 and the auxiliary roller 26 to rotate. At this time, the material tray contacts the auxiliary roller 26 under the action of gravity. Therefore, the auxiliary roller 26 rotates to assist the driving roller 23 in driving the material tray to be conveyed from the outlet side to the downstream until the material tray completely disengages from the feeding channel 25;

[0060] The retraction of the jacking cylinder 1 drives the conveying assembly 2 back to the horizontal position, and the water buffer is used to buffer the impact force at the moment of reaching the position. Then the lifting cylinder 281 drives the blocking member 282 to rise to block the outlet side of the feeding channel 25, and then the conveying of the next material tray starts. Thus, it circulates continuously to complete the continuous conveying of the material tray.

[0061] In summary, the flipping mechanism of this embodiment is simple, convenient, and labor-saving in operation, and can effectively improve the working efficiency, accuracy, stability, and safety of the material tray conveying.
