Description

Technical Field

[0001] The utility model belongs to the technical field of oral liquid preparation, and particularly relates to a bottle conveying device for entering a clean area, and more particularly to a bottle conveying device for feeding an oral liquid bottle into a cleaning device in the clean area. Background Technique

[0002] In the production line of oral liquid, in order to avoid air pollution of the oral liquid, it is often necessary to establish a clean area on the production line, and glass bottles are sent in through a material transfer window opened on the side wall of the clean area wall.

[0003] The glass bottles are loaded into turnover trays. The traditional method is to unpack from the original carton packaging and then load them into a specified stainless steel tray. After a certain number, they are transferred from the non-clean area to the clean area (through a buffer room and changing clean clothes), and then transferred to the buffer room with the stainless steel tray, and then transferred to an automatic bottle washing machine for cleaning, and finally the oral liquid can be filled into the glass bottle. Or the stainless steel tray is sent from the non-clean area to the clean area through the transfer window. The gate of the transfer window needs to be opened and closed repeatedly, and the operator needs to hold the tray.

[0004] For example, the patent with the application number CN202123234011.0 discloses a transfer window device, including: a box body used as a material transfer path, which transfers materials from a positive-pressure material supply area to a material storage area through the box body; the box body includes a first partition in the upper part and a second partition in the lower part, the pressure of the first partition is higher than that of the second partition and lower than that of the material supply area; a first material transfer unit arranged between the first partition and the material supply area for transferring materials from the material supply area to the first partition; a second material transfer unit arranged between the first partition and the second partition for transferring materials from the first partition to the second partition; a controller for controlling the first material transfer unit and the second material transfer unit to alternately execute material transfer. The first material transfer unit includes a lifting door capable of opening and closing the transfer path between the material supply area and the first partition; the second material transfer unit includes a flip door capable of opening and closing the transfer path between the first partition and the second partition, and the lifting door and the flip door are controlled by the controller to alternately open and close to execute material transfer.

[0005] Such multiple transfers are prone to the phenomena of bottle breakage and dropping to the ground. And passing back and forth between the clean area and the non-clean area through the stainless steel tray is a cross-contamination behavior for the requirements of Good Manufacturing Practice (GMP) for drug production quality management; this will reduce the quality of drugs. And using a transfer window usually requires four operators (two in the non-clean area, one for unpacking and the other for sending the tray; two in the clean area, one for receiving the tray and the other for putting the glass bottle into the washing machine), and there is also a risk of the glass bottle dropping. Summary of the Utility Model
