Description
~6~11 The present invention relates to a filllng machine for handling liquid products.
Filtering and filling of solutions for medical use today necessitates two systems, one for filtering and one for filling the filtered solution. The equipment required for these operations occupies great space and is difficult to clean, as well as to connect and to disconnec~. When small and medium sized batches are required the filtering and filling steps of the pro-duction sequence take up too much time, because of the work needed for accommodating and cleaning.
The present invention provides a machine with which it ~ is possible to filter a prepared solution, and to fill it in j measured quantities into the desired containers in a compact, closed system, which may be easily connected, is easily cleaned and occupies a small space.
The present invention also improves the environmental conditions by supplying a machine operating at a low noise level, and where it is possible to reduce the amount of residues escap-ing to the ambient atmosphere. A low noise level may be obtained by using pneumatic operation, which furthermore can easily be designed for automatic operation without any electric components.
¦ This is especially advantageous when handling products including ~- volatile solvents.
When solutions intended for medical use are involved, there is a high demand for sterile handling, and it is essential that the filter be tested before, as well as after a filling a sequence. A filter intended to be used for sterile handling of solutions for medical use has very fine cappillaries, not exceed-ing 0.22 ~m, which are sufficient for blocking the passage of germs and spores. The test is conventionally performed by a so called bubble-point test, and a machine according to the invention is provided with means for performing such tests in a simple manner.
,, 76~
According to the present invention there is provided ~ a filling machine for handling liquid products, comprising at : least one quantitation pump, at least one piston servo motor directly connected to the pump for driving the same, means .j adapted to determine the stroke of the piston servo motor, non-return valves fitted at the pump and adapted to permit the liquid product to be drawn into, and expelled from, the pump, depending upon the direction of movement of its piston, a filter mounted in an outlet conduit from the quantitation pump, and valve means ~ 10 in a supply conduit leading to the quantitation pump, and adapted ,~ at will, to interrupt the connection between a source supplying ;3 the liquid product, and to permit the testing of the filter by ~ subjecting it to the action of pressurized gas, or air.
The filling machine according to the invention thus ;~ includes at least one quantitation pump, at least one piston servo "1 motor directly connected to the pump for driving the same, means ., .
adapted to determine the stroke of the piston servo motor, and non-return valves fitted at the pump and adapted to permit the liquid product to be drawn into, and expelled from the pump, depending upon the direction of movement of its piston, a filter mounted in the outlet conduit from the quantitation pump, and valve means in the supply conduit leading to the quantitation pump, and adapted, at will, to interrupt the connection between the source supplying the liquid product, and to permit the testing of the filter by subjecting it to the action of pressur-ized ~as, or air.
,.
The valve means is preferably arranged to permit the .
quantitation pump alternatively to draw in ambient air, and to force this air through the filter for testing the same. l'he valve means may however, alternatively be designed, for the same purpose, to connect the supply conduit which a source of pre-surrized gas. The filling machine according to the invention preferably includes two parallel quantitation pumps, complete with inlet and outlet fittings, and at least one driving servo motor mounted between the pumps. The servo motor advantageously is a piston servo motor, having throttling means for governing the amount of air passing through the motor. The means deter-mining the stroke of the servo motor preferably comprises a toothed rack fitted in parallel to its longitudinal axis, a cross bar for cooperation with said rack and an final position adjust-ment screw, carried by the cross bar.
¦ 10 The present invention will be further illustrated by way of the accompanying drawings in which:
Figure 1 is a plan view a filling machine according to one embodiment of the invention, ~, Figure 2 shows an elevation, partly in section of the machine, and , Figure 3 shows a front view of the machine.
Referring to the accompanying drawings the machine is adapted to handle medium sized batches of liquids intended for medical use, and to make possible a filling of two bottles simultaneously.
The machine is provided with two parallel cylinders 10 of quantitation pumps, and two cylinders 11 of a double acting piston servo motor interposed between the quantitation cylinders 10. All four piston rods 12 and 13, respectively, of these cylinders are interconnected by means of a yo1ce 14. Pumps and servo motors are`des~igned for the same length of stroke, and the pistons of all four cylinders will thus move synchronously for-wardly and backwardly.
Servo motors 11 are supplied with motive fluid, such as compressed air, via a conduit 15 connected to a suitable source (not shown). Two branch pipes 16 and 17 supply motive fluid to ~ opposite ends of each servo motor cylinder 11. An axially dis-placeable valve 18 is conventionally adapted, to connect one of the branch pipes, 16 and 17, with supply conduit 15, while simultaneously opening the other branch pipe to the atmosphere.
A throttle valve 19 is present in supply conduit 15 by which it is possible to determine the pressure of the motive fluid supplied to the servo cylinders 11, and thus also the speed of the filling. A pressure yauge 20 shows the pressure within the ¦ system. This further includes safety and emergency stop fittings, ~ which are not shown in the drawing, as they form part of con~
¦ 10 ventional equipment.
Displacement of valve 18 may be arranged in any suitable manner. For illustration purposes the drawing shows that the ~ valve body is biased by a spring 21 for movement in one direction, i and that it may be moved in the opposite direction by an activ-ating member 22, which is displaced when a bottle 23 is moved into position for filling.
~ The solution which is to be distributed is stored in -~ a tank 24 (Figure 3), which via a conduit 25 is connected to :1 each quantitation cylinder 10. There is a valve housing, having two non-return valves 26 and 26a, respectively, at each cylinder, ~ one of said non-return valves permitting flow into the cylinder, ¦ but preventing flow in the opposite direction, while the other 3 valve permits flow out of the cylinder, but pxevents flow into the same. The pumps, thus, can draw in fluid and then expel it at a pressure made necessary by the equipment downstream of the i pumps.
In the pressure conduit 27 from each pump there is a filter 28, and from the same a conduit 29 is extended to a pos-ition suitable for the filling operation. It will thus be possible to fill two bottles imultaneously - the operator takes 3 one bottle 23 in each hand and presses the bottles against the ~ machine. This is, as is evident from Figure 1, provided with ", _ ~ _ .
. _ O
guides 30 for the bottles, directed towards the suitable filling ~i positions. The activating member 22 for operating valve 18 is mounted in conjunction with one of those guides.
The quantity to be expelled is determined by selecting the length of the pump stroke. Two toothed racks 31 extend axially away from the cylinders, and a cross bar 32 may be fitted in any suitable position along the two racks, in order to block the movements of piston rods 12 and 13 out of the cylinders. In ;~ order to allow a fine adjustment of the stop position cross bar;~ 10 32 is provided with an adjustment screw 33, having locking means.
;~ The filters 28 are important components with respect j to the handling and it is desirable that the filters be controlled ~ before a filling cycle is started, and also are checked when the J filling is terminated, to establish that no filter has been damaged. Such checking is normally performed by a so called bubble-point test, which, in short, means that the pressure for forcing a column of liquid through the capillaries of the filter is measured. The filter is first saturated with the liquid to t be filtered, and excess liquid is then drained off, whereupon compressed air, or pressurized gas, is supplied. The pressure is slowly increased and the pressure, at which a sudden flow of air, or gas, through the filter occurs, is noted, i.e. the pressure at which the moisture is forced out of the filter.
Established values for various filters, used with given solutions and at known temperatures are tabulated, and will provide a fully satisfactory gauge for the adaptability of the filter used.
In order to make possible bubble-point tests at the machine, each inlet to a pump cylinder is provided with a three way valve 34, which can interrupt the connection with supply conduit 25 and connect the filter to a compress~d air conduit 15a. Alternatively, valve 34 may be adapted to communicate the pump inlet directly with the ambient air. The pump will then `Z76~1 . .
have to draw in air and thereafter force it through the filter.
It will then be necessary to have pressure gauges at the pump _ outlets for such tests. Other gases may be used instead of air.
By using the quantitation pumps for the bubble-point tests it is possible to operate with higher pressures than are normally 3 available in service systems, supplying compressed air in localities, where machines of this type are expected to be used.
The filling volumes may, in a practical embodiment, vary between 2 ml and 100 ml per stroke, and conduit 29 may be formed to permit filling of bottles or ampoules of any desired size. A
machine of this type can, of course, operate with a single j quantitation cylinder and one servo cylinder, and the machine shown can be provided with a single servo cylinder instead of the two of the present design.
In order to make possible a rapid cleaning and steril--izing, the quantitation cylinders are easily detachable, and if some sets of cylinders are provided it is possible, rapidly to ~ switch over from one solution to another. All condllits and -; fittings, coming into contact with the solutions, are preferably manufactured of stainless material, and are designed with a view to permit easy handling and cleaning.

¦ 10 The present invention will be further illustrated by way of the accompanying drawings in which:
Figure 1 is a plan view a filling machine according to one embodiment of the invention, ~, Figure 2 shows an elevation, partly in section of the machine, and , Figure 3 shows a front view of the machine.
Referring to the accompanying drawings the machine is adapted to handle medium sized batches of liquids intended for medical use, and to make possible a filling of two bottles simultaneously.
The machine is provided with two parallel cylinders 10 of quantitation pumps, and two cylinders 11 of a double acting piston servo motor interposed between the quantitation cylinders 10. All four piston rods 12 and 13, respectively, of these cylinders are interconnected by means of a yo1ce 14. Pumps and servo motors are`des~igned for the same length of stroke, and the pistons of all four cylinders will thus move synchronously for-wardly and backwardly.
Servo motors 11 are supplied with motive fluid, such as compressed air, via a conduit 15 connected to a suitable source (not shown). Two branch pipes 16 and 17 supply motive fluid to ~ opposite ends of each servo motor cylinder 11. An axially dis-placeable valve 18 is conventionally adapted, to connect one of the branch pipes, 16 and 17, with supply conduit 15, while simultaneously opening the other branch pipe to the atmosphere.
A throttle valve 19 is present in supply conduit 15 by which it is possible to determine the pressure of the motive fluid supplied to the servo cylinders 11, and thus also the speed of the filling. A pressure yauge 20 shows the pressure within the ¦ system. This further includes safety and emergency stop fittings, ~ which are not shown in the drawing, as they form part of con~
¦ 10 ventional equipment.
Displacement of valve 18 may be arranged in any suitable manner. For illustration purposes the drawing shows that the ~ valve body is biased by a spring 21 for movement in one direction, i and that it may be moved in the opposite direction by an activ-ating member 22, which is displaced when a bottle 23 is moved into position for filling.
~ The solution which is to be distributed is stored in -~ a tank 24 (Figure 3), which via a conduit 25 is connected to :1 each quantitation cylinder 10. There is a valve housing, having two non-return valves 26 and 26a, respectively, at each cylinder, ~ one of said non-return valves permitting flow into the cylinder, ¦ but preventing flow in the opposite direction, while the other 3 valve permits flow out of the cylinder, but pxevents flow into the same. The pumps, thus, can draw in fluid and then expel it at a pressure made necessary by the equipment downstream of the i pumps.
In the pressure conduit 27 from each pump there is a filter 28, and from the same a conduit 29 is extended to a pos-ition suitable for the filling operation. It will thus be possible to fill two bottles imultaneously - the operator takes 3 one bottle 23 in each hand and presses the bottles against the ~ machine. This is, as is evident from Figure 1, provided with ", _ ~ _ .
. _ O
guides 30 for the bottles, directed towards the suitable filling ~i positions. The activating member 22 for operating valve 18 is mounted in conjunction with one of those guides.
The quantity to be expelled is determined by selecting the length of the pump stroke. Two toothed racks 31 extend axially away from the cylinders, and a cross bar 32 may be fitted in any suitable position along the two racks, in order to block the movements of piston rods 12 and 13 out of the cylinders. In ;~ order to allow a fine adjustment of the stop position cross bar;~ 10 32 is provided with an adjustment screw 33, having locking means.
;~ The filters 28 are important components with respect j to the handling and it is desirable that the filters be controlled ~ before a filling cycle is started, and also are checked when the J filling is terminated, to establish that no filter has been damaged. Such checking is normally performed by a so called bubble-point test, which, in short, means that the pressure for forcing a column of liquid through the capillaries of the filter is measured. The filter is first saturated with the liquid to t be filtered, and excess liquid is then drained off, whereupon compressed air, or pressurized gas, is supplied. The pressure is slowly increased and the pressure, at which a sudden flow of air, or gas, through the filter occurs, is noted, i.e. the pressure at which the moisture is forced out of the filter.
Established values for various filters, used with given solutions and at known temperatures are tabulated, and will provide a fully satisfactory gauge for the adaptability of the filter used.
In order to make possible bubble-point tests at the machine, each inlet to a pump cylinder is provided with a three way valve 34, which can interrupt the connection with supply conduit 25 and connect the filter to a compress~d air conduit 15a. Alternatively, valve 34 may be adapted to communicate the pump inlet directly with the ambient air. The pump will then `Z76~1 . .
