Glass tube picking and collecting device

The invention discloses a glass tube rejecting and collecting device which is provided with a buffering device, an interval blanking device, a conveying device, a tube shifting device and a collecting frame, so that waste glass tubes rejected from a rejecting device fall into the interval blanking device through buffering of the buffering device; the interval blanking device controls the releasing speed of the glass tube rejecting pipes to be matched with the conveying speed of the conveying device, the glass tube rejecting pipes falling on a bearing block of the conveying device are conveyed to the pipe shifting device, the glass tube rejecting pipes are shifted into the collecting frame from the bearing block through shifting of a pipe shifting fork of the pipe shifting device, and the glass tube rejecting pipes are collected. And the waste collection work is completed. And through reutilization of waste products or sale according to B-grade products, the yield of the products is improved, and the productio
