Freeze-drying preparation stacking and transfer system and control method

Abstract

The invention discloses a freeze-drying preparation stacking and transfer system and a control method. The system comprises a bottle inlet push rod and a bottle inlet net belt; the bottle inlet net belt is provided with a stacking sleeve frame section, a buffer section and a bottle outlet section; a sleeve frame conveying belt is arranged along the bottle inlet net belt; a sleeve frame loading device is arranged beside the sleeve frame conveying belt; and the bottle inlet push rod is provided with a sleeve frame unloading device for automatically grabbing a sleeve frame and feeding the sleeve frame onto the sleeve frame conveying belt after releasing sleeve frame bottle queues. The method comprises the following steps: (S1) input bottles are stacked; and the bottle queues are input in the sleeve frame; (S2) the sleeve frame bottle queues are fed into the buffer section to wait bottle discharge; (S3) one set of sleeve frame bottle queues is fed to the bottle outlet section; the sleeve frame unloading device is in butt joint with the sleeve frame; the sleeve frame bottle queues are pushed to the freeze dryer plate layer; and the bottle inlet push rod is retracted to enable the sleeve frame to release the bottle queues; and (S4) the sleeve frame is fed to the sleeve frame conveying belt; the bottle inlet push rod is returned or prepared to push the sleeve frame bottle queues, waiting bottle discharge, on the next bottle inlet net belt; and the sleeve frame conveying belt transfers the sleeve frame to the bottle inlet end of the bottle inlet net belt to wait loading.

Description

technical field [0001] The invention relates to the production technology of freeze-dried preparations, in particular to a freeze-dried preparation stacking transfer system and a control method. Background technique [0002] The freeze-dried preparation stacking transfer system sends the semi-stoppered vials to the shelf of the freeze dryer, mainly through the feed integration device, bottle unscrambling device and feed push rod. After the freeze-drying process cycle is completed, the discharge pusher The rod combined with the discharge integrated 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 automatically controlled by the control system, without manual intervention, avoiding manual contact with the product, thereby preventing pollution during the product transfer process to the greatest extent, so the stacking and transferring system of freeze-dried prepa...

Problems solved by technology

[0008] There are too many linkage objects. For example, the linkage objects of the feeding link include: feeding platform, filling line and feeding trolley, feeding trolley and multiple freeze dryers, freeze dryer, feeding trolley and discharging trolley, etc., introduced New failure points, and the increase of linkage links at the same time, the overall speed of a single unit is actually reduced; in the feeding stage before entering the freeze-drying box, in order to avoid aseptic contamination, the medicine bottle needs to be kept in the A-level area. Although the trolley itself has laminar flow protection for the linkage fishing of the trolley, the dead zone in many linkage links increases the risk of product contamination
