[0016] The present invention is described more fully below using embodiments. The present invention can be embodied in many different forms and should not be construed as being limited to the exemplary embodiments described herein.

[0017] For ease of description, spatially relative terms such as "upper", "lower", "left", "right", etc. may be used herein to describe the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the elements described as being "below" other elements or features will be positioned "above" other elements or features. Therefore, the exemplary term "lower" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here can be interpreted accordingly.

[0018] In this embodiment, the sterilization process area and the sterilized product storage area are both clean areas; setting up a partially enclosed clean area can greatly reduce energy consumption and management difficulty compared to setting up the entire workshop as a clean area, and is more conducive to avoiding product contamination. The solution of the present invention solves the problem of product transportation between two unconnected clean areas.

[0019] The sterilization vehicle (not shown in the figure) is composed of several layers of stacked trays, and each layer of trays is arranged with multiple infusion products.

[0020] like Figure 1 As shown, the post-sterilization infusion container transfer system in this embodiment includes a first clean area 1 and a second clean area 2; a transfer device 3 for transferring infusion containers is arranged between the first clean area 1 and the second clean area 2. In order to prevent the outside of infusion containers such as infusion bags and infusion bottles from being contaminated by pollutants in the environment, the transfer device is provided with a closed storage cabin 302 for transferring the infusion containers. At the same time, the storage cabin is provided with a high-efficiency filter part 303, which is composed of a fan and a high-efficiency filter; the high-efficiency filter filters the air blown in by the fan to obtain gas that meets the requirements of the clean area, fills the storage cabin with gas and ensures that the storage cabin is slightly high pressure relative to the outside; prevents air in the environment from entering the storage cabin through the gap; the storage cabin is provided with a double-opening door 304, the height of the door is basically the same as the height of the storage cabin, and is at least greater than 4 / 5 of the height of the storage cabin; a sterilization vehicle with more layers can be transported, which is beneficial to improving the transportation efficiency; and reducing the number of transfers.

[0021] The transfer device can use a commercially available AGV trolley as a base; the accommodating cabin is arranged on the top of the AGV trolley body; a cabin support rail 305 is arranged below the cabin door; the cabin door driving mechanism is arranged above the cabin door; the driving mechanism (not shown in the figure) can adopt existing technologies such as chains, cylinders or electric cylinders.

[0022] The driving mechanism for driving the sterilization vehicle to move outward or inward is preferably a roller; the motor drives the plurality of rollers to rotate via a sprocket, so that the sterilization vehicle is connected to the accommodation cabin or pushed out from the accommodation cabin.

[0023] You can choose the RGV trolley, which runs on tracks, has a large load capacity, is simple to control and operate, and has lower costs.

[0024] In order to reduce the leakage of clean gas, a hatch sealing strip 306 may be provided between the hatch and the door of the accommodating chamber.

[0025] A docking port for the transfer of infusion containers is provided in front of the partition wall 201 of the clean area docked with the transfer device; the sterilization vehicle carrying the sterilized infusion product enters the storage compartment of the transfer device through the track of the docking port; similarly, the sterilization vehicle in the storage compartment enters the finished product storage area through the track of the docking port; a hatch support sub-rail 203 supporting the opened hatch can be provided at the docking port; in this way, the length of the transfer device can be reduced, and the transfer operation can be facilitated; at the same time, the hatch opening is smoother. At least the hatch support sub-rail of the transfer device can move downward, and avoid the hatch support rail on the transfer device before the transfer device is in place; when the transfer device is in place, it moves upward and aligns with the hatch support rail in the horizontal and vertical directions. The driving mechanism (not shown in the figure) that drives the hatch support sub-rail up and down can adopt existing technologies such as chains, cylinders or electric cylinders.

[0026] The distance between the hatch of the transfer device and the docking port is relatively close, and an air curtain 202 may be arranged above the door of the docking port to transport clean gas through the air curtain in advance and reduce pollutants in the docking space.

[0027] The docking interface may also be provided with a wind shield 204 to seal the docking area, thereby forming a closed area or an air duct, thereby improving the efficiency of removing low-cleanliness gas.

[0028] The hatch support rail and the hatch support auxiliary rail are both provided with grooves, and rollers are arranged in the grooves to reduce the resistance of opening and closing the hatch.

[0029] When using the sterilized infusion container transport system in this embodiment, the steps are as follows: 1) The transfer device moves toward the target clean area, and when approaching the interface of the target clean area, the target clean area discharges clean gas to the interface area; 2) The transfer device is docked with the docking port, and the door of the docking port is fully opened; 3) The door support rail rises and aligns with the door support rail; 4) The door of the storage compartment is fully opened; 5) Transferring infusion containers between transfer devices and clean areas; 6) The door of the containment compartment is completely closed, and the door support rail is lowered to avoid the situation; 7) Close the door of the interface completely.

[0030] If the interface of the target clean area is provided with an air curtain, clean gas is discharged from the interface area through the air curtain in step 1).

[0031] If no wind curtain is provided, the door of the interface of the target clean area can be opened from the direction of the transfer device, and the door gap can be gradually enlarged; the gas in the clean area is discharged from the door gap; in step 1), the clean gas is discharged from the interface area through the door gap.

[0032] If the speed at which the door gap expands is synchronized with the speed of the transfer device, a wind duct can be formed by utilizing the door of the transfer device and a wind shield adjacent to the door, thereby reducing the amount of gas loss in the clean area.

[0033] By adopting the sterilized infusion container transport system and method of the present invention, a laminar flow section and a storage cabin for sterilized infusion containers can be added to the RGV, so that sterilized infusion bags, infusion bottles and other containers can be automatically or remotely controlled for transport; operators do not need to enter the clean room; thereby avoiding environmental pollution caused by human activities and preventing the sterilized infusion containers from being contaminated.

[0034] The above examples are only used to illustrate the present invention. In addition, there are many different implementations. These implementations are all conceivable by those skilled in the art after understanding the concept of the present invention. Therefore, they are not listed here one by one.
