Feed guide device and method of freeze dryer

Abstract

The invention discloses a feed guide device of a freeze dryer. The device comprises guide plates and a driving piece, wherein the guide plates are arranged at the two sides of a feed push rod of the freeze dryer, and are positioned above a bottle outlet rail of the freeze dryer; the guide plates are connected with the driving piece through a connecting rod; and the connecting rod is driven by the driving piece to drive the guide plates to ascend and descend. The invention further discloses a feed guide method of the freeze dryer; the method comprises the following steps: in feeding, the guide plate far from an inlet of the bottle outlet rail descends, and the guide plate near the inlet of the bottle outlet rail ascends; arranged bottles are counted and positioned to finish once arrangement of double rows of small bottles; the guide plate near the inlet of the bottle outlet rail descends, and the small bottles are pushed to a pushing area; and the guide plate near the inlet of the bottle outlet rail ascends to finish the feeding. The guide device and method both have the advantages of simple structure, increase of feeding speed and prevention of extruding explosion of the small bottles.

Description

technical field [0001] The invention mainly relates to the field of packaging machinery for medicine, food, etc., in particular to a feed guiding device and method for a freeze dryer. Background technique [0002] The automatic loading and unloading of the freeze dryer sends the semi-stoppered vials to the shelf of the freeze dryer through the feeding integration device and bottle unscrambling device combined with the feeding push rod. After the freeze-drying process cycle is completed, the discharge push rod is combined with the discharge The 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 controlled by the control system without manual intervention, avoiding manual contact with the product, thereby preventing the product from being damaged during the transfer process to the greatest extent. pollution, so the use of automatic feeding and dischargin...

Problems solved by technology

[0005] The double-row automatic feeding and discharging equipment realizes the dislocation effect of the odd and even rows and the control of the gap between the vials in each row after counting the bottles through the double-star wheel. When buffering the platform or the shelf of the freeze dryer, due to the friction of the contact surface between the vial and the track, it is easy for the front side vial row to slide to the two sides during the process of being pushed. If this phenomenon occurs, it will cause problems: 1. 1. The effect of dislocation of odd and even rows will be completely disrupted, and the rows of vials will be in a state of random arrangement. The random arrangement will also affect the number of vials on a single shelf of the freeze dryer, reducing the production efficiency of pharmaceutical companies; 2. On the bottle output track The number of bottles in each row is set according to the actual situation, and is strictly and precisely controlled by the star wheel, but the vials sliding to both sides are not controlled, and it is very possible to increase the number of bottles on both sides of the row at the rear side, so that the feeding In the process of pushing the push rod forward, there is a risk that the extra vials on the rear side will be crushed by the feed push rod and the barrier assembly, which also brings the risk of product contamination and equipment damage
