Lyophilizer input and output material butt joint state detecting method and butt joint system

Abstract

The invention discloses a lyophilizer input and output material butt joint state detecting method. The method comprises the following steps that (1) whether a lifting driving component falls down or not is monitored in the falling process of the turnover plate, and if the turnover plate does not fall down, failure treatment is carried out; (2) whether the turnover plate and a bridge plate are in bridge connection or not is detected, and if the turnover plate and the bridge plate are not in bridge connection, the failure treatment is carried out; (3) whether the bridge plate and a lyophilizer shelf are in butt joint or not is detected, and if the bridge plate and the lyophilizer shelf are not in butt joint, the failure treatment is carried out. The invention further discloses a lyophilizer input and output material butt joint system which comprises the turnover plate, the bridge plate, the lifting driving component, a horizontal movement driving component, a control unit, a lifting detection component, a horizontal movement detection component and a butt joint detection component, and the control unit outputs control instructions to control one or more of the lifting driving component, the horizontal movement driving component and a lyophilizer according to the detection signals of the lifting detection component, the horizontal movement detection component and the butt joint detection component. The method and system have the advantage of guaranteeing the smooth and stable butt joint of the lyophilizer.

Description

technical field [0001] The invention mainly relates to the technical field of feed and discharge materials of a freeze dryer, in particular to a detection method and a docking system of a feed and discharge docking state of a freeze dryer. Background technique [0002] Vacuum freeze dryer is a machine that uses the principle of vacuum freeze-drying to cool and freeze water-containing substances into a solid state, and then directly sublimate water vapor from the solid state under vacuum conditions. The vacuum freeze dryer has a front box and a condenser (cold trap), and the front box is equipped with a shelf that can be raised and lowered. The main function of the shelf is to carry the drugs that need to be freeze-dried, and the shelf has cooling and heating. It can provide the necessary conditions for the production of medicines. [0003] The connection between the shelf of the freeze dryer and the fixed automatic feeding and discharging mesh belt is an important link for ...

Problems solved by technology

[0004] 1. If the connecting rod of the flap and the lap joint of the bridge plate are not engaged, the extension action is performed, resulting in a false report of the successful docking signal, so that the connecting rod and the bridge plate collide with each other during the extension of the flap, resulting in damage Equipment security risks

[0005] 2. If the connecting rod of the flap flap is retracted without confirming that it is engaged with the lap joint of the bridge plate, it will cause a false report of the retraction signal of the bridge plate, which will lead to a collision with the bridge plate during the subsequent lifting process of the shelf of the freeze dryer, which is erroneous.
