[0026] In one embodiment of this utility model, such as Figures 1-4As shown, a right-angle transfer device is provided, including a support platform 1, a turntable 2, a traction component 3, and a detection component 4. The support platform 1 is provided with a rotary drive 11. The turntable 2 is rotatably disposed on the top of the support platform 1, and its axis is connected to the main shaft of the rotary drive 11. The traction component 3 is disposed on the top of the turntable 2 and has a linear conveying area 31 that acts on the material. The detection component 4 includes several pairs of photoelectric switches 41, which are arranged along the length of the linear conveying area 31. The material moves through the linear conveying area 31 of the traction component 3 towards one end near the turntable 2 until the light signal transmission of the pair of photoelectric switches 41 at the end of the linear conveying area 31 is blocked. At this time, the linear conveying area 31 stops working and the rotation drive 11 drives the turntable 2 to rotate 90°. Finally, the linear conveying area 31 outputs the material in the opposite direction, thereby completing the material transfer. In this embodiment, the detection component 4 detects the position of the material on the linear conveying area 31 and adjusts the fixed conveying stroke to the required conveying stroke for the material to move into the turntable 2. The rotation is reversed only when the material is completely on the turntable 2, which helps to reduce the situation where the material falls off during the reversal process.

The housing of the reducer is fixed to the bottom of the support platform 1, the input end is connected to the main shaft of the motor, and the output end is rotatably engaged with the bracket and fixedly connected to the center bottom of the turntable 2. The working principle of this embodiment is: (1) providing a transverse conveying device and a longitudinal conveying device, and splicing them with the transfer device of this embodiment to form a right-angle conveying system; (2) transverse conveying, the material moves on the transverse conveying device until it is detected by the photoelectric switch 41 located at the head end of the turntable 2; (3) traction of the material, the photoelectric switch 41 located at the head end transmits an electrical signal to the information processing component, and the information processing component transmits a start signal to the linear conveying area 31. (4) Conveying direction change: The material moves in the linear conveying area 31 until it is detected by the photoelectric switch 41 at the end of the turntable 2. The photoelectric switch 41 at the end transmits an electrical signal to the information processing component. The information processing component transmits a stop signal to the linear conveying area 31 and a start signal to the rotary drive 11 respectively until the first section of the linear conveying area 31 is connected to the longitudinal conveying device. (5) Longitudinal conveying: The linear conveying area 31 transports the material in the direction until it is detected by the photoelectric switch 41 at the first end of the turntable 2. At this time, the linear conveying area 31 can stop working or continue working until all photoelectric switches 41 do not detect the material. Finally, it is reset and the above process (2) to (5) is repeated in sequence.

The transmission wheels 342 are coaxially connected to the outer ends of the conveying wheels 32 and are synchronously driven through the transmission belts 343. Specifically, the transmission wheels 342 are multi-wedge wheels, and the transmission belts 343 are multi-wedge belts. Two adjacent multi-wedge wheels are driven by a multi-wedge belt.
