The two measuring sensors 50 are spaced apart along the transport direction a of the tube and are located at an end of the first conveyor belt 113 that is remote from the baffle 20. The controller 60 is fixed on the first bracket 111, and the trigger sensor 40 and the measurement sensor 50 are electrically connected to the controller 60, and the controller 60 is configured to receive and transmit signals from the trigger sensor 40 and the measurement sensor 50, and receive, convert and transmit the signals.

Referring to fig. 2, the conveying mechanism 10 is used for conveying a pipe, the pipe abuts against the baffle 20 arranged at the discharging position on the conveying mechanism 10, the trigger sensor 40 arranged on the back surface 22 of the baffle 20 receives the abutting signal of the pipe and the blocking surface 21, and the signal received by the trigger sensor 40 is transmitted to the two measuring sensors 50 arranged at intervals.

The position where one end of the pipe is abutted to the blocking face 21 is set to be a zero scale position, the two measuring sensors 50 are positioned on the conveying mechanism 10 and are arranged at intervals along the conveying direction A of the pipe, meanwhile, the measuring sensors 50 are arranged on one side, far away from the baffle plate 20, of the first support 111, the measuring sensor 50 close to one side of the baffle plate 20 is used for determining the standard size requirement of the pipe, the other measuring sensor 50 is used for controlling the maximum size requirement of a workpiece, and the position between the two measuring sensors 50 is within the error range requirement of the pipe, namely, the pipe is qualified.

The second conveyor 123 receives the tube on the first conveyor 113, and when the qualified tube passes through the pushing assembly 126, the pushing assembly 126 is not operated, and the qualified tube is conveyed along the qualified member conveying space 1251 on the second conveyor 123 into the receiving box 70 disposed at the rear of the qualified member conveying space 1251.

When the unqualified pipe passes through the material pushing assembly 126, the material pushing assembly 126 acts, the material pushing driving element 1261 pushes the material pushing element 1262 to push towards the direction perpendicular to the second conveyor belt 123, so that the unqualified pipe is pushed to the waste conveying space 1252, and the unqualified pipe is conveyed to the inbox 70 arranged at the tail part of the waste conveying space 1252 through the waste conveying space 1252 on the second conveyor belt 123.

Referring to fig. 1, in some embodiments, the measuring apparatus further includes an inbox 70, and at least two inboxes 70 are disposed at the end of the second conveyor 123 for receiving the qualified workpieces and the unqualified workpieces, respectively.

Specifically, two inboxes 70 are respectively placed at the tail of the qualified piece conveying space 1251 and the tail of the waste piece conveying space 1252, qualified pipe pieces are conveyed into the inboxes 70 placed at the tail of the qualified piece conveying space 1251 along the qualified piece conveying space 1251 on the second conveyor 123, unqualified pipe pieces are conveyed into the inboxes 70 placed at the tail of the waste piece conveying space 1252 through the waste piece conveying space 1252 on the second conveyor 123, separation of qualified pieces and unqualified pieces is achieved, and qualified pieces and unqualified pieces can be collected and sorted into the inboxes 70.
