Automatic discharge method and discharge device of freeze dryer

Abstract

The invention discloses an automatic discharging method for a freeze dryer. The automatic discharging method comprises the following steps: carrying out bottle blockage monitoring on conveyer belts on a discharging conveyer channel, and controlling the rotation directions of the conveyer belts with bottle blockage to dredge the bottle blockage. The invention also discloses an automatic discharging device for the freeze dryer. The automatic discharging device comprises a discharging conveyer channel, wherein the discharging conveyer channel comprises a conveyer belt assembly which is used for arranging a plurality of lines of bottles into a single line; the conveyer belt assembly comprises a plurality of independent conveyer belts which are butted in sequence along the discharging direction; a first bottle body detection member is arranged on the conveyer belt assembly and used for detecting whether the conveyer belts have bottle blockage or not and sending detection signals to a control assembly; the control assembly is used for switching the rotation directions of corresponding conveyer belts according to the detection signals so as to dredge blocked bottles. Both the method and the device disclosed by the invention have the advantages of being simple to operate, rapid in feeding speed, and capable of full-automatically monitoring the bottle blockage and automatically and rapidly dredging the bottle blockage.

Description

technical field [0001] The invention mainly relates to the technical field of freeze-drying machines, in particular to an automatic discharging method and a discharging device of a freeze-drying line. Background technique [0002] The automatic loading and unloading of the freeze dryer passes the semi-stoppered vials through the feeding integration device and bottle unscrambling device, and sends them to the shelf of the freeze dryer combined with the feeding push rod. After completing the freeze-drying process cycle, it is combined by the discharge push rod The integrated discharge device sends the vials out of the shelf, and transfers them to the capping machine and subsequent processes. The entire feeding and discharging process is completely controlled by the control system without manual intervention, avoiding manual contact with the product, thereby preventing the transfer process of the product to the greatest extent. The pollution caused in the environment, so the us...

AI Technical Summary

Problems solved by technology

Although the current discharge method can meet a certain degree of process requirements, the transfer monitoring of the discharge link is relatively weak. If a blockage occurs, the control system does not have corresponding automatic processing measures, and it relies heavily on manual intervention. As a result, a series of problems have been brought about; in addition, when the products produced by the automatic feeding and discharging and the freeze dryer are such as 50ml and other large-scale bottle products, blockages are also prone to occur in the area where the freeze dryer shelf is connected to the conveyor belt, but here There are no monitoring or treatment measures in the area, so the vials continue to be pushed out after clogging and squeezed with the feed push rod, resulting in bottle bursting, which brings the risk of product contamination and equipment damage

Therefore, due to the above deficiencies, the discharge speed cannot be set too fast, so as to avoid major failures and fail to improve production efficiency.
