Screening and transporting device and screening and transporting method for containers

Abstract

The invention relates to a screening and transporting device and a screening and transporting method for containers. The screening and transporting device for the containers comprises a transportation mechanism, a leakage detection mechanism, a rejection mechanism and a controller, wherein the transportation mechanism is used for transporting the containers; the leakage detection mechanism is used for detecting whether the containers have air leakage faults or not; the rejection mechanism is used for rejecting the containers which are detected to have the air leakage faults out of the transportation mechanism; the transportation mechanism, the leakage detection mechanism and the rejection mechanism are respectively connected with the controller. According to the screening and transporting device for the containers, firstly the containers with air leakage are detected by using the leakage detection mechanism, signals of the containers with the air leakage are sent to the controller, and when the containers are transported to a rejection position provided with the rejection mechanism, the controller controls the rejection mechanism to reject the containers with the air leakage out of the transportation mechanism. Thus, the containers transported from the transportation mechanism are all have no air leakage fault. Obviously, the containers which have the air leakage faults can be fast and conveniently rejected, and a whole process is high in automation degree.

Description

technical field

[0001] The invention relates to the technical field of container processing, in particular to a container screening and transportation device and method. Background technique

[0002] Containers, such as bottles, barrels, boxes, etc., need to be tested for leakage after processing is completed.

[0003] Existing leak detection methods often use water detection, that is, wait for a period of time after adding water, and observe whether there is water leakage. However, the water detection method not only has low detection efficiency, but also requires a long detection waiting period, and the detection accuracy is not high. Moreover, the water inspection needs to consume a lot of water resources. In addition, if the drainage is not clean, it will also cause water accumulation inside the container, which will affect the product quality. Moreover, manual testing is currently adopted, and its testing efficiency is low and time-consuming. Contents of the inventi...
