Description
Technical Field
The utility model relates to a feed liquor system and a corresponding liquid filling machine for liquid filling machine.
Background
In the filling field, in particular in the field of pharmaceutical filling, filling machines are generally used for filling pharmaceutical substances into corresponding containers, for example glass bottles. After filling, the container may be sealed to enclose the medicament in the container.
Liquid drugs often have different properties, particularly different liquid properties, depending on the composition. For example, some drugs are in the form of clear liquids without precipitation, and some drugs are in the form of suspensions with precipitation. It will be appreciated that drug precipitation causes the density to become non-uniform, such that even if the same amount of liquid is filled into the respective containers, the effective amount of drug or the relative proportions of the drug components in each container are not consistent, which is highly undesirable for subsequent patient treatment.
For this reason, different filling machines are often used to solve the above problems. However, the use of different filling machines for different medicaments means on the one hand an increase in the equipment costs and on the other hand also increased labor costs due to the need to equip the different filling machines with corresponding operating personnel. Moreover, the increase in the number of filling machines also means that a larger working area is required for placing these filling machines.
Therefore, there is a pressing need for improvements to existing filling machines.

Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and a plurality of exemplary embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the scope of the invention.
Fig. 1 shows a schematic diagram of an inlet system of a filling machine adapted to be filled with liquids of at least two different characteristics according to an exemplary embodiment of the present invention.
As shown in fig. 1, the liquid inlet system 1 includes at least: a liquid separating unit 11, a pump 12, a first flow path 13 adapted to be established in a first operating state in fluid connection with at least the liquid separating unit 11 and the pump 12, and a second flow path 14 adapted to be established in a second operating state different from the first operating state in fluid connection with the liquid separating unit 11 and the pump 12, wherein in the first operating state the inlet system 1 is configured to be able to feed a first liquid having a first characteristic to the liquid separating unit 11 by means of the pump 12 in a first manner, and in the second operating state the inlet system 1 is configured to be able to feed a second liquid having a second characteristic different from the first characteristic to the liquid separating unit 11 by means of the pump 12 in a second manner different from the first manner.
The first and second operating states, the first and second modes are described in an open manner, which means that the inlet system 1 of the invention is not limited to being suitable for filling with liquids of only two different properties, but is also suitable for filling with liquids of a third different property, for example by establishing a third flow path.
The liquid dispensing unit 11 may dispense the liquid supplied thereto into respective containers, such as vial bottles, ampoule bottles, etc., under the control of a controller (not shown).
By providing the filling machine with such a liquid inlet system 1, the same filling machine can be adapted to fill liquids of at least two different characteristics, so that there is no need to provide a corresponding filling machine for each liquid, which greatly saves equipment costs, labor costs and space costs.
According to an exemplary embodiment of the present invention, the liquid separation unit 11 may be configured as a liquid separation tube.
According to an exemplary embodiment of the present invention, the first flow path 13 and the second flow path 14 are established manually, e.g. by manually connecting hoses. However, it will also be understood by those skilled in the art that the present invention is not limited thereto, but the first flow path 13 and the second flow path 14 may also be established, for example, by switching of respective valves.
The first liquid having the first characteristic may be a clear liquid, and the second liquid having the second characteristic may be a suspension. It will be appreciated that a first liquid, for example a clarified liquid, may be stored in the first reservoir 21 and a second liquid, for example a suspension, may be stored in the second reservoir 22, the first flow path 13 being fluidly connected to the first reservoir 21 and the first liquid being pumpable from the first reservoir 21 in a first operating condition, and the second flow path 14 being fluidly connected to the second reservoir 22 and the second liquid being pumpable from the second reservoir 22 in a second operating condition.
In the following, the invention will be exemplarily described with reference to fig. 1 to better understand the basic idea of the invention.
According to an exemplary embodiment of the present invention, as shown in fig. 1, the liquid inlet system 1 further comprises a buffer tank 15 for buffering the first liquid, in the first operating state, the first flow path 13 is fluidly connected to the buffer tank 15, and in the second operating state, the buffer tank 15 is fluidly isolated from the second flow path 14 without allowing the second liquid to enter the buffer tank 15.
According to an exemplary embodiment of the present invention, in the first operating condition, the buffer tank 15 is fluidly connected at the other end of the liquid separating unit 11 opposite to the end to be connected to the supply of the first liquid, i.e. the first reservoir 21. In other words, the buffer tank 15 and the supply source of the first liquid are fluidly connected to opposite ends of the dispensing unit 11, respectively, as shown in fig. 1.
According to an exemplary embodiment of the present invention, in the second operating state, a circulation flow path of the second liquid is established between the second reservoir 22 and the liquid separation unit 11 via the second flow path 14.
According to an exemplary embodiment of the present invention, in the first operating state, the first reservoir 21, the pump 12, the liquid separating unit 11 and the buffer tank 15 are sequentially connected in series and fluidly connected. In operation, pump 12 pumps the first liquid from first reservoir 21, then feeds the first liquid through liquid separation unit 11 into buffer tank 15, and fills buffer tank 15 to a first predetermined level, and then pump 12 may be turned off and liquid in buffer tank 15 is used by liquid separation unit 11 for filling. When the liquid level in the buffer tank 15 drops to the second predetermined level due to filling, the pump 12 is restarted to replenish the buffer tank 15 with the first liquid to the first predetermined level, so that the liquid level in the buffer tank 15 can be maintained between the first predetermined level and the second predetermined level at all times during filling.
To establish the above-described series fluid connection, first reservoir 21 is fluidly connected to pump 12 via a first flow line 131, pump 12 is fluidly connected to dispensing unit 11 via a second flow line 132, and dispensing unit 11 is fluidly connected to surge tank 15 via a third flow line 133. In this case, the pump 12 may pump the first liquid from the first reservoir 21 through the first flow line 131, then the pump 12 may supply the pumped first liquid to the liquid separation unit 11 through the second flow line 132, and then the first liquid may continue to be supplied from the liquid separation unit 11 to the buffer tank 15 through the third flow line 133 (as indicated by the corresponding arrows in fig. 1). During the filling operation, the first liquid can be supplied again to the liquid separation unit 11 via the third flow line 133, but does not continue to flow back to the first reservoir 21.
Thus, according to an exemplary embodiment of the present invention, the first flow path 13 may comprise a first flow line, a second flow line and a third flow line.
The first flow line 131 may include at least one first removable line segment 1311. Preferably, the first detachable section 1311 of tubing may be configured as a hose (schematically represented in fig. 1 in a curved shape, the tubing represented in fig. 1 in a straight line may be constructed to be rigid). The first removable pipeline section 1311 may be removed for cleaning or replacement.
As shown in fig. 1, a first valve 1321 may be disposed on the second flow line 132, and the first valve 1321 may be used to control the flow path between the pump 12 and the dispensing unit 11. For example, the first valve 1321 may be closed when the buffer tank 15 is filled to a first predetermined level to control the backflow of the first liquid.
As shown in fig. 1, a second valve 1331 may be provided in the third flow line 133, and the second valve 1331 may be used to control the flow of liquid to the buffer tank 15. For example, in a first operating state, the first liquid is allowed to flow to the buffer tank 15, and in a second operating state, the second liquid is prevented from flowing to the buffer tank 15.
According to an exemplary embodiment of the present disclosure, in the second operating state, a fluid connection may be established between the end of the portion-separating unit 11 remote from the pump 12 (i.e., the end to be connected to the buffer tank 15 in the first operating state) and the second reservoir 22, so that a circulation flow path may be established as shown in fig. 1 (circulation flow is indicated by the corresponding arrows in fig. 1). As shown in fig. 1, a fluid connection may be established between the end of the dispensing unit 11 remote from the pump 12 and the second reservoir 22 via a fourth flow line 141. In particular, the end of the fourth flow line 141 adjacent to the liquid separation unit 11 is connected between the liquid separation unit 11 and the second valve 1331, so that the second liquid can only circulate by closing the second valve 1331 to prevent the second liquid from entering the buffer tank 15.
Similarly, the fourth flow line 141 may include at least one second removable line segment 1411. Also similarly, the second removable line segment 1411 may be configured as a hose.
The output port of the second reservoir 22 is fluidly connected to the pump 12 similar to the first operating condition. It will be appreciated that the output port of the second reservoir 22 may also be fluidly connected to the pump 12 through at least a portion of the first flow line 131. Thus, in the second operating state, relative to the first operating state, the second flow path 14 is established only by connecting the fourth flow line 141 and closing the second valve 1331.
In this case, the pump 12 sucks the second liquid from the second reservoir 22 and then feeds it into the liquid separation unit 11, and the excess second liquid in the liquid separation unit 11 is returned to the second reservoir 22 through the fourth flow line 141, thereby establishing a circulating flow of the second liquid. This circulating flow is very advantageous for suspended liquids, so that the second liquid is homogeneous without settling.
It will be appreciated by those skilled in the art that the connection of the fourth flow line 141 may be made manually or by control of a corresponding valve.
According to an exemplary embodiment of the present disclosure, the first liquid and/or the second liquid is sucked from the bottom of first reservoir 21 and/or second reservoir 22. In the second operating condition, the second liquid is returned from the top of second reservoir 22 to second reservoir 22.
It will be appreciated by those skilled in the art that although in the first and second operating conditions shown in fig. 1, both the first and second liquids are supplied from the pump 12 to the liquid separation unit 11, in the second operating condition, the pump 12 may be operated in reverse to circulate the second liquid in a circulation direction opposite to that shown in fig. 1, while the second liquid is preferably still drawn from the bottom of the second reservoir 22 and returned from the top of the second reservoir 22 to the second reservoir 22. In this case, the pump 12 is preferably configured as a bidirectional pump. Such a configuration will be apparent to those skilled in the art and will not be described herein for clarity.
When changing feed liquor system 1 from first operating condition to second operating condition, need disinfect to the pipeline that first liquid flowed through, the detachable part can be dismantled and get off to disinfect or directly change for clean. And vice versa.
According to an exemplary embodiment of the present disclosure, the filling machine may be a vial filling machine, a pre-fill needle filling machine, or an ampoule filling machine.
According to an exemplary embodiment of the present invention, the filling machine may also be configured to be able to perform a sealing function, which may be referred to as a filling and sealing machine at this time.
Although specific embodiments of the invention have been described in detail herein, they have been presented for purposes of illustration only and are not to be construed as limiting the scope of the invention. Various substitutions, alterations, and modifications may be devised without departing from the spirit and scope of the present invention.
