Problems solved by technology

Since this solution can’t treat advanced mails differently, it can’t accurately control the distance between single output mails and mails, making the distance between most mails far greater than the set parameters, and the efficiency of single mail separation and delivery is obviously low

Abstract

The invention discloses an improved structure of a single mail separating device, which comprises a separating conveyor belt mesh which is configured transversely, wherein a first negative-pressure air valve, a second negative-pressure air valve, a first travel detection head and a travel-ending detection head are configured on one side of the separating conveyor belt mesh in sequence along the conveying direction; a plurality of travel detection heads are uniformly arranged between the first travel detection head and the travel-ending detection head and along the separating conveyor belt mesh; and when the second negative-pressure air valve is closed, if the detection heads from the first to the ith are all in a started state and the other travel detection heads behind the ith travel detection head are in a closed state, the second negative-pressure air valve is closed to compensate for corresponding time and then re-opened. In the invention, the plurality of travel detection heads are uniformly arranged between the first travel detection head and the travel-ending detection head to accurately quantify a crossover distance of excess mails, different compensations and time delays with pertinence are provided to improve the distance accuracy between the mails, and thus, the single mail separating efficiency of the device is further improved.

Description

technical field [0001] The invention relates to the technical field of postal services, in particular to postal letter sorting machines, flat piece sorting machines and other mail single envelope separating devices. Background technique [0002] In the letter sorting machine of the postal logistics system, the single mail separation device is an important device. Its main function is to separate the mail delivered by the automatic letter supply mechanism and output them one by one at a certain interval, so that Each message is processed in the next step. [0003] In the currently used double negative pressure valve single-sealing separation device, its basic structure includes a horizontally arranged separation conveying mesh belt, and one side of the separating conveying mesh belt is sequentially equipped with a first negative pressure valve and a second negative pressure valve along the conveying direction. , the first stroke detection head and the end stroke detection he...
