Automatic feeder and cut end detection device thereof

Abstract

The invention discloses an automatic feeding machine and a cut end detection device thereof. The cut end detection device comprises a detection piece located at the discharging end, and a sensor used for sensing the position change of the detection piece is arranged on one side of the detection piece; the detection piece is connected with a first rotating shaft which is connected with a transmission assembly, the transmission assembly is connected with a motor, and the motor is used for driving the transmission assembly to enable the first rotating shaft to rotate. The device is used for detecting whether a material is fed or not during blanking and calculating the distance from the end face of the material to a machine tool by taking the cut end at the moment as a reference, detection is carried out after the material is blanked and when the material is discharged from the discharging end, the detection time is optimal at the moment, and detection does not need to be carried out before; the detection sheet is jacked up when the material is sent out, whether the material exists or not is judged according to the position change of the detection sheet, and the detection structure is high in reliability and easy to implement; and when the material continues to be sent out, the detection piece can be controlled to be lifted to leave the material through the transmission assembly, and the detection piece is prevented from affecting material machining.

Description

technical field [0001] The invention belongs to the technical field of feeding, and in particular relates to an automatic feeding machine and a cutting end detection device thereof. Background technique [0002] The prior art provides an automatic feeder, which can automatically send materials such as round or special-shaped (including rectangular, square, hexagonal, etc.) metal bars to machine tools for processing. During the feeding process, the automatic feeding machine sends the material to the machine tool processing place through the feeding rod until the front end of the material reaches the machine tool equipment for processing, such as cutting and segmenting. After each section of material is processed by the machine tool, the feed rod will continue to push the last section of the material to the processing position until the material is divided into multiple sections, then the feed rod will bring back the tail material, and the automatic feeder will push a new mate...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, some use sensors for direct detection, such as using metal induction sensors for detection, and some use mechanical structure induction detection. These detection methods are not reliable, especially when the material is small, the material has a bend, or the end surface of the material When the edge is warped, the detection distance will be far and short, resulting in unreliable detection results, and their detection functions are independent and cannot be linked with the entire feeding process. The calculation basis for the distance from the end face of materials of different lengths to the machine tool is not uniform. , leading to the opening and closing of its detection function out of sync with the machine, complex control, low reliability and low production efficiency
