Description

Technical Field

[0001] The present application relates to the technical field of filling equipment, and more specifically, to a dual-control dual-flow tube filling device and a filling system. Background Art

[0002] Currently, there are many demands for large-volume liquid packaging with specifications above 2000ml in clinical medicine, which are mainly used for cleaning fluids, disinfectants, nutrient solutions or dialysis fluids, etc. The packaging forms include bags, bottles, barrels, etc.

[0003] However, the current common equipment filling application scenarios all use the control method of an independent large-diameter single valve. The disadvantages of this control method are: the filling process is prolonged, resulting in a corresponding increase in the cycle time of the entire automatic production line, and the production capacity of the production line cannot be fully utilized, resulting in resource occupation and waste; secondly, before the filling is almost completed, the large-diameter valve is used for rapid and high-flow filling and is prone to liquid flow impact, which affects the metering accuracy; finally, before the filling is almost completed, the large-diameter valve is used for rapid and high-flow filling and is prone to liquid flow impact, which causes the drug solution to overflow the container, affecting the filling accuracy and not meeting GMP requirements.

[0004] Therefore, there is an urgent need for a filling device that can achieve fast and large-flow filling, so that most of the liquid medicine can be poured into the container in a short time, and at the same time, the flow rate can be accurately controlled at the end of the filling stage to ensure fast and accurate filling. Utility Model Content

[0005] To address the above technical issues, the present application provides a dual-control dual-flow tubular filling device. Through dual control, rapid, high-flow filling is performed at the beginning of filling, allowing most of the liquid medicine to be poured into the container in a short period of time. At the end of filling, filling is performed using a small-diameter valve port. This filling method ensures rapid and accurate filling while effectively eliminating the flow shock that can easily occur with rapid, high-flow filling using a large-diameter valve, leading to inaccurate metering. It also prevents undesirable phenomena such as liquid medicine overflowing from the container. This also improves production efficiency.

[0006] The present application provides a dual-control dual-flow tubular filling device, the specific technical solution of which is as follows: a filling pipeline, a liquid supply pipeline;

[0007] The filling pipeline specifically includes: a flow meter, a connecting pipe, a double-control double-flow tube-type pneumatic diaphragm valve and a filling nozzle connected in sequence;

[0008] The liquid supply pipeline provides filling liquid to the filling pipeline, and under the monitoring of the flow meter, the filling liquid is transported to the filling nozzle through the double-control double-flow tubular pneumatic diaphragm valve;

[0009] At the beginning of filling, the double-control double-flow tubular pneumatic diaphragm valves are all opened for fast and large-flow filling; at the end of filling, the double-control double-flow tubular pneumatic diaphragm valves are closed, and the side pneumatic diaphragm valve without an adjustable limit is closed, allowing the filling metered amount to enter the small-diameter valve port of the other side pneumatic diaphragm valve with an adjustable limit to complete the filling.

[0010] Preferably, the specific structure of the liquid supply pipeline includes: a liquid distribution pipe, a liquid inlet, a reflux port, and a diaphragm pressure gauge;

[0011] The filling liquid enters the dispensing pipe from the liquid preparation room through the delivery pump and terminal filtration, and the dispensing pipe is connected to the filling pipeline;

[0012] In order to ensure that the liquid pressure in the dispensing tube is relatively stable, the dispensing tube is provided with the reflux port corresponding to the end opposite to the liquid inlet, and the dispensing tube is also provided with a diaphragm pressure gauge for detecting the liquid pressure.

[0013] Preferably, the liquid supply pipeline is connected to several groups of the filling pipelines, and each of the filling pipelines can achieve independent filling.

[0014] Preferably, the connecting pipe is an integrated silicone hose.

[0015] Preferably, the filling pipeline further includes a manual diaphragm valve, which is arranged between the liquid dispensing tube and the flow meter.

[0016] Preferably, the flow meter is specifically measured in one of the following ways: mass flow meter measurement, turbine flow meter measurement, pressure time measurement, or a combination of these.

[0017] Preferably, the flow meter is electrically connected to the signal feedback of the double-control double-flow tubular pneumatic diaphragm valve, and the double-control double-flow tubular pneumatic diaphragm valve is controlled by the metering signal feedback of the flow meter.

[0018] Preferably, the dual-control dual-flow tubular pneumatic diaphragm valve is detachably arranged in the filling pipeline, and different diameter sizes can be selected according to actual filling needs, and the setting with a built-in adjustment limit button can be flexibly selected.

[0019] Preferably, the filling nozzle is installed on the filling pipeline through a filling nozzle mounting plate.

[0020] At the same time, the present application also provides a dual-control dual-flow tubular filling system using the dual-control dual-flow tubular filling device, the specific structure of which includes: a frame, a filling lifting device, a station to be filled, a bottle pushing device, a filling station, a filled station and a control and operating system;

[0021] Under the control of the control operating system, the container to be filled is transported to the to-be-filled station via the conveying track, the bottle pushing device pushes the container to be filled to the filling station, and the filling lifting device extends the filling nozzle into the container for filling. After the filling is completed, the bottle pushing device pushes the completed container to the filled station via the next group of to-be-filled containers, and then transports it to the next station via the filled conveying track.

[0022] The double-control double-flow tubular filling device provided by the present invention is provided with a double-control double-flow tubular pneumatic diaphragm valve. It can be seen that compared with the prior art, the filling device in the embodiment of the present invention can achieve two-stage filling control. At the beginning of filling, the double-control double-flow tubular pneumatic diaphragm valves are all opened at the same time, and a large flow rate is filled quickly, so that most of the liquid is poured into the container in a short time. At the end of filling, by closing the side pneumatic diaphragm valve without an adjustable limit, the filling metering is allowed to enter the small-diameter valve port of the other side pneumatic diaphragm valve with an adjustable limit for filling. This filling method ensures fast filling and accurate filling. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] This specific embodiment of the present invention is written in a progressive manner.

[0036] like Figures 1 to 3 As shown, the embodiment of the present invention provides a dual-control dual-flow tube-type filling device 1, which mainly includes two major pipeline systems: a filling pipeline and a liquid supply pipeline;

[0037] The filling pipeline is a unit for directly filling the container, and its specific structure includes: a flow meter 1-1, a connecting pipe 1-2, a double-control double-flow tubular pneumatic diaphragm valve 1-3 and a filling nozzle 1-4 connected in sequence;

[0038] like Figure 2 and Figure 3 As shown, in this embodiment, the liquid supply pipeline is used to provide filling liquid to the filling pipeline, and under the monitoring of the flow meter 1-1, the filling liquid is transported to the filling nozzle 1-4 through the double-control double-flow tubular pneumatic diaphragm valve 1-3;

[0039] Compared with the direct filling structure in the prior art, in this embodiment, the dual-control dual-flow tubular filling device 1 opens all the dual-control dual-flow tubular pneumatic diaphragm valves 1-3 at the beginning of filling to achieve rapid and high-flow filling; at the end of filling, the dual-control dual-flow tubular pneumatic diaphragm valves 1-3 are closed, and the side pneumatic diaphragm valve without an adjustable limit is closed, allowing the metered amount of filling to enter the small-diameter valve port of the other side pneumatic diaphragm valve with an adjustable limit to complete the filling;

[0040] By using the dual-control dual-flow tubular filling device 1 provided in this embodiment, this filling method ensures fast and accurate filling, effectively eliminates the flow impact that is easily generated by fast and high-flow filling of large-diameter valves, which leads to inaccurate metering, and prevents adverse phenomena such as liquid medicine overflowing from the container. Furthermore, production efficiency is improved.

[0041] As a preferred Figure 2 and Figure 3 As shown, the specific structure of the liquid supply pipeline in this embodiment is further defined. In this embodiment, the specific structure of the liquid supply pipeline includes: a liquid distribution pipe 1-5, a liquid inlet 1-6, a reflux port 1-7, and a diaphragm pressure gauge 1-8;

[0042] As a component unit for supplying filling liquid to the filling pipeline, in this embodiment, the filling liquid passes through the delivery pump and terminal filtration from the liquid preparation room and enters the liquid distribution pipe 1-5 from the liquid inlet 1-6, and the liquid distribution pipe 1-5 is connected to the filling pipeline;

[0043] At the same time, in order to ensure that the liquid pressure in the dispensing tube 1-5 is relatively stable, the dispensing tube 1-5 is provided with the reflux port 1-7 at the opposite end to the liquid inlet 1-6, and the dispensing tube 1-5 is also provided with a diaphragm pressure gauge 1-8 for detecting the liquid filling pressure in the dispensing tube 1-5 to ensure that the pressure in the dispensing tube 1-5 is basically stable.

[0044] Furthermore, in order to better fill the container with liquid, the filling pipeline is further defined. In this embodiment, Figure 2 As shown, the liquid supply pipeline is connected to a plurality of groups of filling pipelines, each of which can realize independent filling, and can realize filling of multiple containers at the same time, thereby improving the production efficiency of the filling device.

[0045] Preferably, the form of the connecting tube 1-2 in this embodiment is further limited. Since the filling pipeline will undergo axial movement when the container is filled, in order to ensure the smoothness of the filling action and avoid damage to the connecting tube 1-2 due to axial movement, the connecting tube 1-2 is specifically an integrated silicone hose, which can avoid rupture due to stretching of the connecting tube 1-2 during axial movement.

[0046] Preferably, in order to better control the filling pipeline, the components of the filling pipeline in this embodiment are defined, such as Figure 2 and Figure 3 As shown, the filling pipeline also includes a manual diaphragm valve, which is arranged between the dispensing tube 1-5 and the flow meter 1-1. Through the setting of the manual diaphragm valve, the operator can stably control the pressure in the dispensing tube 1-5, and can also perform an emergency stop operation when an emergency occurs in the filling device to avoid causing a larger production accident.

[0047] Preferably, as a component for measuring the filling pipeline with flow meter 1-1, the flow meter 1-1 has many metering modes on the market. In this embodiment, the specific metering mode of the flow meter 1-1 is not limited. It can select a suitable metering mode according to different situations, which can be one of mass flow meter measurement, turbine flow meter measurement, pressure time measurement, or a combined metering mode.

[0048] More preferably, in this embodiment, the control method of the double-control double-flow tubular pneumatic diaphragm valve 1-3 is further limited, and the flowmeter 1-1 is electrically connected to the signal feedback of the double-control double-flow tubular pneumatic diaphragm valve 1-3. Through the metering signal feedback of the flowmeter 1-1, the opening and closing of the part of the side pneumatic diaphragm valve without adjustment limit and the opening and closing of the part of the side pneumatic diaphragm valve with adjustment limit in the double-control double-flow tubular pneumatic diaphragm valve 1-3 can be controlled successively.

[0049] Furthermore, due to the diversity of filling containers, in order to better adapt to a variety of filling containers and improve the available range of the filling device, in this embodiment, the dual-control dual-flow tubular pneumatic diaphragm valve 1-3 is detachably arranged in the filling pipeline, and different diameter sizes can be selected according to actual filling needs. For example, DN10 can be selected for less than 5000ml; DN20 can be selected for greater than 5000ml and less than 10000ml; and the setting of the self-contained adjustment limit button can be flexibly selected, and a double-sided self-contained adjustment limit button can be selected, or a single-sided self-contained adjustment limit button can be selected. This is mainly selected according to actual conditions and filling accuracy requirements.

[0050] Further, if Figure 2 As shown, the installation structure of the filling nozzle 1-4 in this embodiment is further limited. Since the filling nozzle 1-4 needs to move axially, in this embodiment, the filling nozzle 1-4 is installed on the filling pipeline through the filling nozzle 1-4 installation plate.

[0051] At the same time, this embodiment also discloses a dual-control dual-flow tubular filling system including the dual-control dual-flow tubular filling device 1, such as Figure 4 and Figure 5 As shown, in this embodiment, in addition to the dual-control dual-flow tubular filling device 1, it also includes: a frame 2, a filling lifting device 3, a waiting filling station 4, a bottle pushing device 5, a filling station 6, a filled station 7 and a control and operating system 8;

[0052] like Figure 4 and Figure 5 As shown, the dual-control dual-flow tubular filling system is a frame structure with the frame 2 as the main body, and the filling production line runs through it. The dual-control dual-flow tubular filling system is introduced from the perspective of the container filling route flow.

[0053] Under the control of the control operating system 8, the container to be filled passes through the conveying track and is conveyed horizontally to the right to the to-be-filled station 4. The bottle pushing device 5 then moves horizontally to the right to push the container to be filled to the filling station 6. The filling lifting device 3 moves vertically downward to extend the filling nozzles 1-4 into the container for filling. After filling is completed, the filling lifting device 3 moves vertically upward and, after passing through the following group of containers to be filled, is pushed by the bottle pushing device 5 to push the completed container to the filled station 7. The container is then conveyed to the next station via the filled conveying track to complete the liquid filling of the container.

[0054] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
