Multi-line feeding system of freeze dryer and feeding method thereof

Abstract

The invention discloses a multi-line feeding system of a freeze dryer. The multi-line feeding system of the freeze dryer comprises a conveying mesh belt and a freeze-drying box body and further comprises a bottle arranging and organizing device, a transition device and a bottle buffering-pushing device which are used for pre-pushing bottles into the freeze-drying box body and sequentially arranged in the bottle conveying direction of the conveying mesh belt, wherein each of the bottle arranging and organizing device, the transition device and the bottle buffering-pushing device is provided with at least three rows of bottle conveying channels, the bottle conveying channels on the buffering-pushing device, the transition device and the bottle arranging and organizing device are arranged in a one-to-one correspondence mode, and the transition device performs reciprocating translation in the direction perpendicular to the bottle conveying direction of the conveying mesh belt to enable the bottle conveying channels of the transition device to be in opposite connection with the bottle conveying channels of the bottle arranging and organizing device and the bottle buffering-pushing device. The invention further discloses a multi-line feeding method of the freeze dryer. The method comprises the steps of arranging orderless bottles in a multi-line mode to form a bottle queue and then pushing the bottle queue into the freeze-drying box body. The feeding system and the feeding method have the advantages of improving the feeding speed and ensuring the safe feeding.

Description

technical field [0001] The invention mainly relates to the technical field of feeding and discharging materials of a freeze dryer, in particular to a multi-line feeding system of a freeze dryer and a feeding method thereof. Background technique [0002] The automatic loading and unloading of the freeze dryer sends the semi-stoppered vials into the cabinet of the freeze dryer through the feeding integration device, the bottle unscrambling device and the feeding push rod. The 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 discharging is becoming more and more popular. [0003] Especially in recent years, with th...

Problems solved by technology

At present, the existing single-line/double-line automatic feeding and discharging equipment can increase the overall bottle feeding speed within a certain range even if the running speed of the conveyor belt and star wheel is increased, but the range is limited, generally speaking, 400~600 bottles/min It is the feeding limit speed of this type of single-row/double-row feeding and discharging equipment, and it is difficult to have a greater improvement

Moreover, with the unilateral increase in the speed of the conveyor belt, the probability of bottle inversion in the track is correspondingly increased, and the consequences are as follows: 1. The poured bottle is stuck at the corner of the track, causing a blockage, and subsequent bottle transmission If it is blocked, if there is no operator on site to intervene in time, it will remain stagnant, affecting the speed of the entire production cycle; 2. The poured bottle smoothly enters the track near the front end of the star wheel, and the rotating star wheel is frequently overloaded or squeezed with the bottle , severely damage the edges and corners of the star wheel, and damage the automatic feeding and discharging equipment

On the other hand, with the acceleration of the speed of the star wheel, according to a large number of experiments, it has been found that it will also lead to the following problems: 1. If the front-end bottle transmission fails to transfer the bottle continuously at a
