Detection device and detection method for upward edge folding of single mails in mail piles

Abstract

The invention discloses a detection device and a detection method for the upward edge folding of single mails in mail piles, and relates to the field of logistics transportation. The device comprisesa support platform fixed to a rack and used as the bottom surface of the rack, a lifting mechanism arranged at the bottom of the rack, penetrates through the support platform, and carrying out up-downmovement along a first vertical slide rail, a mirror-image detector fixed to the side arm of the rack, a mirror-image lens arranged on an attached pressing mechanism and on the side arm of the rack,and the attached pressing mechanism fixed to the upper part of the rack and carrying out up-down movement along a second vertical slide rail. The method comprises the following steps: a mail box heldwith the mail piles is transmitted to the support platform; the lifting mechanism moves upwards along the slide rail, penetrates through a through hole in the bottom of the mail box, and lifts the mail piles, the attached pressing mechanism and the mirror-image lens together; and when the mirror-image lens is lifted to reach the height of the mirror-image detector, whether the mail piles are normal or not is judged through judging whether the light path of the mirror-image detector is normal or not. According to the detection device and the detection method, detection for the abnormal states of the mail piles with different thicknesses is realized through the dynamic detection method in the lifting process.

Description

technical field [0001] The invention relates to the field of logistics transportation, in particular to a detection device and method for upward folding of a single mail in a mail stack. Background technique [0002] At present, flat mail has been automatically sorted in the logistics process, and the sorted mail falls into the collection container, and multiple mails are piled up in the collection container to form mail piles with different thicknesses. During the process of mail falling into the collection container, although most of the mail will fall into the container flatly, there will also be some cases where the hem of the mail will be lifted, and the lifted mail will protrude from the mail stack, resulting in abnormalities on the upper surface of the mail stack, which will affect the next process . Contents of the invention [0003] The purpose of the present invention is to provide a detection device and method for upward folding of a single mail in a mail stack...
