The transfer assembly 20 is arranged on the support plate 32, the support plate 32 is connected to the lifting cylinder 31, and the piston end of the lifting cylinder 31 is arranged downward.

[0021] The transfer assembly 20 has a conveying state and a transfer state. In the conveying state, the transfer belt 21 is not higher than the conveying roller 11, and the article can move from the conveying roller 11 to the transfer belt 21; in the transfer state, the transfer belt 21 is higher than the conveying roller 11, the moving direction of the transfer belt 21 is perpendicular to the conveying direction of the roller conveyor 10, and the article is located on the transfer belt 21. The lifting cylinder 31 acts to lift the support plate 32 and the transfer assembly 20 thereon, changing the transfer assembly 20 from the conveying state to the transfer state.

[0022] The roller conveyor 10 includes a plurality of conveying rollers 11 arranged at intervals. The plurality of conveying rollers 11 are driven to rotate in the same direction simultaneously. An article is located on the conveying rollers 11 and is driven to move under the rotation of the conveying rollers 11. Baffles are provided at both ends of the conveying rollers 11. The baffles extend along the arrangement direction of the conveying rollers 11 to form stoppers at both ends of the conveying rollers 11 to prevent the article from falling off the conveying rollers 11 during transportation. The contact surfaces of the plurality of conveying rollers 11 are connected to form the conveying surface of the roller conveyor 10. When the roller conveyor 10 transports an article, the central axes of the plurality of conveying rollers 11 are located on the same horizontal plane so that the article moves on the horizontal plane, facilitating the transfer of the article from the conveying rollers 11 to the transfer belt 21. In this embodiment, as Figure 1 and Figure 3 shown, the conveying rollers 11 are driven to rotate by the same motor.

[0023] The transfer assembly 20 includes a transfer belt 21 and a drive motor 25. The transfer belt 21 is wound around a driving wheel 22 and a driven wheel 23. The drive motor 25 is connected to the driving wheel 22, and the drive motor 25 drives the driving wheel 22 to rotate, thereby driving the transfer belt 21 to move. The transfer belt 21 is disposed between two adjacent conveying rollers 11. The upper belt surface of the transfer belt 21 is lower than the conveying surface of the roller conveyor 10, or the upper belt surface of the transfer belt 21 is flush with the conveying surface of the roller conveyor 10 so that in the conveying state, the article will not be blocked by the transfer belt 21, and the article can be smoothly transferred from the roller conveyor 10 to the transfer belt 21.

[0024] In this embodiment, the transfer belt 21 is a synchronous belt. The driving wheel 22 and the transfer belt 21 are in meshing transmission, and the driven wheel 23 and the transfer belt 21 are in meshing transmission to ensure a stable transmission ratio during the transportation of the transfer assembly 20, thereby ensuring the stable movement of the article on the transfer assembly 20.

[0025] The driving wheel 22 and the driven wheel 23 are disposed at both ends of the conveying rollers 11 to completely cover the width of the roller conveyor 10 so that the article can be transferred from the conveying rollers 11 to the transfer belt 21 at any position on the conveying rollers 11. Support plates 32 are disposed at both ends of the conveying pipes, and the driving wheel 22 and the driven wheel 23 are respectively disposed on the support plates 32 at both ends of the conveying rollers 11.

[0026] To reduce the occupation of the bottom space of the roller conveyor 10, in this application, the drive motor 25 is arranged above the roller conveyor 10. Specifically, the drive motor 25 is arranged on the support plate 32. To make up for the height difference between the drive motor 25 and the driving wheel 22, a transmission assembly 40 is also provided. The drive motor 25 drives the driving wheel 22 to rotate through the transmission assembly 40, and then drives the transfer belt 21 to move. The transmission assembly 40 includes a first transmission wheel 41 and a second transmission wheel 42, and a transmission belt 43 wound around the first transmission wheel 41 and the second transmission wheel 42. The first transmission wheel 41 is connected to the output shaft of the drive motor 25, and the second transmission wheel 42 is connected to the driving wheel 22. A synchronous shaft 26 is also arranged on the support plate 32. The driving wheel 22 and the second transmission wheel 42 are both arranged on the synchronous shaft 26. The drive motor 25 drives the first transmission wheel 41 to rotate. Under the action of the transmission belt 43, the second transmission wheel 42 rotates synchronously. The rotation of the second transmission wheel 42 drives the synchronous shaft 26 to rotate, and then drives the driving wheel 22 to rotate, and the transfer belt 21 moves to transfer items. In this embodiment, the output shaft of the drive motor 25 is located above the driving wheel 22, so the first transmission wheel 41 is located above the second transmission wheel 42. In practical applications, the first transmission wheel 41 can also be located below the second transmission wheel 42.

[0027] Furthermore, multiple transfer belts 21 are arranged in parallel at intervals, and multiple synchronous wheels are arranged on the synchronous shaft 26 and are driven to rotate together by the synchronous shaft 26. When the item is transferred from the conveying roller 11 to the transfer belt 21, the multiple transfer belts 21 support the item together, so that the item is stable on the transfer belt 21 to prevent the item from tipping over and falling off the transfer belt 21 during the transfer process.

[0028] An installation seat 24 is also arranged on the support plate 32. The installation seat 24 is fixed on the support plate 32. The installation seat 24 includes two side plates arranged at intervals opposite to each other. The installation seat 24 corresponds to the driving wheel 22. The driving wheel 22 is arranged between the two side plates. The two side plates form stoppers on both sides of the driving wheel 22 to prevent the driving wheel 22 from moving axially. A bearing is also arranged inside the installation seat 24. The synchronous shaft 26 is inserted into the installation seat 24 through the bearing. The synchronous shaft 26 is connected to multiple installation seats 24 at the same time, and the installation seat 24 is used to support the synchronous shaft 26.

[0029] On the other side, the mounting seat 24 is fixed to the support plate 32, and the driven wheel 23 is arranged between the two side plates of the mounting seat 24. In this embodiment, a support shaft is arranged between the two side plates, and each mounting seat 24 is provided with a support shaft. The mounting seat 24 is arranged corresponding to the driven wheel 23, and the driven wheel 23 is rotatably arranged on the support shaft, so that when the driving wheel 22 rotates, the driven wheel 23 can rotate relative to the support shaft, and the driving wheel 22 and the driven wheel 23 cooperate to drive the transfer belt 21 to move. As another implementation manner, bearings are arranged in the mounting seat 24, the support shaft is connected to multiple mounting seats 24 at the same time, the driven wheels 23 are arranged on the support shaft, and the multiple driven wheels 23 cooperate with the support shaft and the driving wheel 22 to achieve synchronous rotation.

[0030] The support plates 32 on both sides of the conveying roller 11 are connected by a connecting plate 27. The connecting plate 27 is arranged below the transfer belt 21 and runs through the width direction of the roller conveyor 10. The two ends of the connecting plate 27 are respectively fixedly connected to the two support plates 32 to realize the synchronous lifting of the two support plates 32.

[0031] The transfer assembly 20 is changed from the conveying state to the transfer state by the lifting assembly 30. In the transfer state, the upper belt surface of the transfer belt 21 is higher than the conveying surface of the roller conveyor 10, the article is separated from the conveying roller 11, and the article is driven by the transfer belt 21 to realize turning. The lifting assembly 30 includes a lifting cylinder 31 and a lifting plate 33 connected to the piston end of the lifting cylinder 31. In this application, the piston end of the lifting cylinder 31 is arranged downward, the support plate 32 is arranged on the lifting cylinder 31, the lifting cylinder 31 drives the lifting plate 33 to move downward, the lifting plate 33 acts on the frame (or the ground), and then the lifting cylinder 31 and the support plate 32 thereon move upward, so as to lift the transfer assembly 20. When the lifting cylinder 31 rises, the transfer belt 21 is changed from the conveying state to the transfer state, the upper belt surface of the transfer belt 21 is higher than the conveying roller 11, the article is driven by the transfer belt 21 to rise and is separated from the conveying roller 11, and then the drive motor 25 drives the transfer belt 21 to move to realize the turning of the article.

[0032] Further, in this application, the transfer assembly 20 is lifted by the movement of the piston end of the lifting cylinder 31. During multiple lifting processes of the piston end, the lifting plate 33 directly acts on the frame multiple times. To reduce the wear of the lifting plate 33 and extend the service life of the lifting plate 33, a gasket is also arranged on the lifting plate 33 for buffering to slow down the wear generated when the lifting plate 33 contacts the frame during each lifting process. In this application, the gasket is a sponge sheet.

[0033] Further, an extension assembly is also arranged along the end of the roller conveyor 10. The extension assembly includes a plurality of conveying rollers arranged at intervals. By arranging the extension assembly, the length of the roller conveyor 10 is lengthened, so that when there are more articles to be transported, the extension assembly can be used to store the articles, and the articles stored on the extension assembly can be moved to the roller conveyor 10 by pushing.
