The transport unit 200. The first conveying part 100 and the second conveying part 200 are rotatably connected, specifically, the first conveying part 100 and the second conveying part 200 are connected through a rotating shaft. The driving mechanism 300 drives the second conveying part 200 to switch between the horizontal state and the upright state. When the second conveying part 200 is in the upright state, it cooperates with the first conveying part 100 to form an "L" shape. rack, as shown in Figure 4. The driving mechanism 300 then drives the receiving frame to turn over 90 degrees as a whole, as shown in FIG. 5 .

The specific application of the present invention is as follows: in the initial state, the first conveying part 100 and the second conveying part 200 are arranged side by side, and materials are directly conveyed thereon in the same state. When it is necessary to change the conveying state of the material, the driving mechanism 300 drives the second conveying part 200 to switch to an upright state, and the cooperation between the first conveying part 100 and the second conveying part 200 forms an "L"-shaped storage rack, and the workpiece 50 enters the receiving rack Inside, the driving mechanism 300 drives the receiving rack to turn over as a whole, and then drives the workpiece to turn over 90 degrees to switch the conveying state of the workpiece. After the switching work is completed, the driving mechanism 300 drives the receiving frame to reset, so that the first conveying part 100 is switched to a horizontal state, and the second conveying part 200 is still in an upright state at this time, and can be used for turning over the next workpiece 50 . When the next workpiece 50 does not need to be turned over, the driving mechanism 300 can be used to drive the second conveying part 200 to switch from the upright state to the lying state, so as to ensure that both the first conveying part 100 and the second conveying part 200 are reset to the initial state , for conveying the workpiece 50 directly. The present invention realizes the function of turning over the workpiece 50 and directly conveying the workpiece 50 on a logistics line. It has a simple structure and complete functions, which saves the equipment investment cost and greatly reduces the occupied space of the equipment.

In this embodiment, the driving mechanism 300 includes a first driving assembly for driving the first conveying part 100 to rotate and a second driving assembly for driving the second conveying part 200 to rotate. Specifically, as shown in FIG. 3 and FIG. 5 , the first driving assembly includes a follower 311 fixed under the first conveying part 100 , a driving wheel engaged with the follower 311 and driving the The motor 315 that drives the wheel to rotate. The driving wheel includes a driving wheel 313 connected with a motor 315 and a transmission wheel 312 located between the driving wheel 313 and the driven member 311 , and the driving wheel 312 meshes with both the driven member 311 and the driving wheel 313 . In addition, the drive wheel 313 is connected to the motor 315 through a reducer 314 . In the present invention, the motor 315 drives the driving wheel to rotate, and the driving wheel then drives the follower 311 to move upward, so that the first conveying part 100 can rotate upward to an upright state. The present invention realizes the overturning of the accommodating frame by means of gear transmission, which can ensure that the accommodating frame rotates smoothly during the overturning process, and its rotational speed is adjustable and controllable, thereby ensuring a stable state switching of the workpiece 50 . Because in the middle and late stages of the reversing of the receptacle, especially when the reversing reaches a critical state (the receptacle is turned over to 45 degrees), since the center of gravity of the workpiece 50 rotates from one side to the other, the force applied by the receptacle to the first drive assembly At this time, if a driving device such as an oil cylinder or an air cylinder is used to drive the first conveying part 100, because the air pressure or hydraulic pressure in the cylinder loses the external pressure, it will quickly drive in a short time. The movement of the piston rod causes the holder to rotate rapidly, and the turning speed of the workpiece is unbalanced, resulting in an unstable turning process of the workpiece. However, the present invention adopts the structure of motor drive plus gear transmission, and utilizes the inherent mechanical characteristics of the induction motor. When the reverse thrust applied to the drive shaft of the motor is converted into the same direction pulling force, the motor speed will not change significantly, thereby realizing the accommodating frame. The overall overturning process is stable and reliable, and the overturning speed is adjustable and controllable. The structure design of the invention is reasonable and ingenious, and the production cost is low.

Preferably, the follower 311 is a gear, and the rotation axis of the follower 311 coincides with the rotation axis of the first conveying part 100. This design can be achieved when the transmission wheel 312 rotates at a constant speed.

The present invention can also use a rack to replace the follower 311 according to actual needs, and the rack should be arranged obliquely on the side of the transmission wheel 312 . In this embodiment, the follower 311 is a semi-circular gear structure, so that the follower 311 can drive the first conveying part 100 at a constant speed, and ensure that the follower 311 can be fixed under the first conveying part 100 , so as not to affect the workpiece transportation on the upper side of the first conveying part 100 . In other embodiments, the driven member 311 and the driving wheel 313 of the present invention can be designed as a sprocket structure, and the transmission is realized through a chain between the driven member 311 and the driving wheel 313. At this time, the driven member 311 should be provided at the side end of the first delivery part 100 , so as to ensure that the rotation axis of the follower 311 coincides with the rotation axis of the first delivery part 100 .

When the first driving assembly drives the first conveying part 100 to rotate to the upright state, the second conveying part can be driven by the second driving assembly (that is, the structure similar to the connecting rod composed of the cylinder 321 and the piston rod 322). The part 200 is rotated to a horizontal state, so as to realize the linkage between the first conveying part 100 and the second conveying part 200, and then realize the turning over of the whole storage rack. The working principle of the driving mechanism 300 is as follows: the piston rod 322 drives the second conveying part 200 to rotate upwards to an upright state, and cooperates with the first conveying part 100 in a horizontal state to form an "L"-shaped storage rack. Afterwards, when the first driving assembly drives the first conveying part 100 to rotate to the upright state, the first conveying part 100 drives the cylinder 321 to move upward at the same time. The conveying part 200 moves down to a horizontal state, so that the storage frame formed by the first conveying part 100 and the second conveying part 200 is turned over as a whole. The present invention realizes the linkage between the first conveying part 100 and the second conveying part 200 through the second driving assembly, and the first driving assembly only needs to drive the first conveying part 100 to rotate, and can drive the entire storage frame to rotate, so that the present invention The structure is simple, the design is reasonable, and the production materials and costs are fully reduced.

Preferably, the second driving component is an oil cylinder, which has a small volume and a relatively large load, and meanwhile, its output adjustment is relatively convenient, and the degree of freedom of transmission is relatively high. The present invention can also select other driving mechanisms 300 such as air cylinders to replace the oil cylinders according to actual needs.
