Article sending system and output pipeline thereof

Abstract

The invention discloses an article sending system and an output pipeline thereof. The article sending system comprises a sending assembly; the sending assembly is connected with an air supply pipeline and the output pipeline; the output pipeline at least comprises a smooth area pipeline and a falling area pipeline; the lower end of the falling area pipeline is a discharging end, and the falling area pipeline is provided with a deceleration buffer area; and a group of friction buffer parts are distributed at the deceleration buffer area from top to bottom at intervals, and the inner cross-sectional area of each friction buffer part is smaller than that of other positions of the falling area pipeline. According to the scheme, a conveyed object continuously makes contact with the multiple friction buffer parts to be continuously decelerated, the falling speed of the conveyed object is reduced to a low range in a layer-by-layer friction mode, impact in the speed reduction process can be effectively reduced through layer-by-layer friction, the problem of blood sample abnormity caused by too high falling speed is also avoided, furthermore, the speed of the conveyed object during output can be effectively reduced, the object is prevented from falling into a material receiving container to cause overlarge impact, and the safety of the container and samples is ensured.

Description

technical field [0001] The invention relates to the technical field of pneumatic conveying, in particular to an item sending system and its output pipeline. Background technique [0002] When transporting blood collection tubes, a feasible way is pneumatic transport. During pneumatic transport, the blood collection tubes need to be placed in a sending channel first, and then the blood collection tubes are transported through the air supply pipeline and output pipeline connected with the sending channel. to the appropriate testing department. [0003] Conventional output pipelines include successively connected lifting zone pipelines, flat zone pipelines and drop zone pipelines. The drop zone pipelines are usually vertically arranged, and the blood collection tubes fall freely in the drop zone pipelines. When the falling speed reaches a certain threshold, abnormalities will occur in the blood sample in the blood collection tube. For example, when the delivery speed of the bl...

[0004] At the same time, when the blood collection tube is output from the pipeline in the drop zone, due to the high output speed, when it enters the receiving container after output, the blood collection tube will collide violently with the receiving container. First, it is easy to damage the blood collection tube. Large shocks also increase the odds of sample abnormalities in blood collection tubes
