Definitions

  • the invention relates to a method for filling a container provided with a metering or atomizing pump with a dispensing, in particular liquid, pasty or gel-like filling medium, in which the container is filled and then the pump is applied tightly to the container opening, and a device for carrying out the Procedure.
  • a dispenser for liquids has become known from DE-A 2 706 800, which has a pump contained in a tube with a hose deformable via a lever. After the container containing the dispensing liquid has been filled, the tubular pump is inserted into a sealed opening in the container and thereby displaces part of the liquid which penetrates into the pump via the inlet valve and thereby fills the pump.
  • This arrangement is limited to a specific design and size of the pump and can hardly be used in the usual installation of atomizing and metering devices on containers by flanging or screwing. Furthermore, this arrangement requires a very easy opening outlet valve of the pump because the pressure with which the liquid penetrates into the pump is very low. Pumps with spring-loaded outlet valves, such as those used for atomizers etc., cannot be filled with them.
  • a device for filling portion containers from a storage vessel has become known.
  • a piston pump is attached to the storage vessel, which is actuated and depressed by the portion container, which has the shape of a piston syringe.
  • the pump pushes its contents into the plunger syringe and pushes the plunger back.
  • this mode of operation presupposes that the pump in the storage vessel is filled beforehand by pumping, since there is no device for pre-filling.
  • a device for withdrawing liquid from bottles has become known.
  • the bottle carries a stopper into which a riser pipe is inserted.
  • the device consists of a nozzle arranged in a bell, to which a rubber ball is connected. After squeezing the rubber ball, place it on the stopper so that the nozzle is connected to the riser pipe and the liquid is sucked out. There is no valve or pump on this device, the chamber of which could be filled.
  • the object of the invention is to prepare a metering or atomizing pump before first use so that it fulfills its function after only one or a few actuation strokes.
  • This object is achieved by a method in which, after the application, the outlet valve of the pump is opened and filling medium is sucked into the pump by exerting a vacuum on the outlet channel, and the outlet valve is then closed, as a result of which this filling is maintained.
  • the pump is actuated on the one hand in such a way that the outlet valve opens, and on the other hand it is applied with the opening of the outlet channel to a negative pressure relative to the container pressure, here called vacuum .
  • the medium is sucked up into the pump chamber while the inlet valve opens automatically.
  • the use of a vacuum instead of suction by actuating the pump not only saves a significant amount of time, but also has many advantages.
  • the suction is preferably carried out only up to the outlet valve.
  • the size of the vacuum, its exposure time and the passage cross section of the outlet duct downstream of the outlet valve can advantageously be dimensioned such that little or no filling medium penetrates into the outlet duct when it is sucked in.
  • the vacuum should be sufficient to produce a quick filling of the pump chamber through the inlet valve, the volume resistance of the outlet valve, the size of the vacuum and its exposure time are so coordinated that the medium cannot flow over the outlet valve.
  • the individual values of the reference values depend on the structural conditions of the pump and the viscosity of the filling medium.
  • outlet channel remains free means that the filling medium cannot dry up and clog the outlet channel and an atomizing nozzle provided thereon, for example. Contamination of medium remaining in the outlet channel is also prevented.
  • the invention is particularly suitable for metering and atomizing pumps which generate a very high pressure of several bars and build up this pressure in the pump chamber before the outlet valve opens.
  • these pumps the valve cross-section of the exhaust valve is so small that the above requirements can easily be met.
  • the vacuum is not sufficient around the outlet valve to open. For this reason, it is necessary with these pumps to open the outlet valve by forced actuation. This can be done by moving the pump piston, which acts as a component of the outlet valve by means of an elastic section, against a fixed stop, so that the outlet valve opens.
  • Such a pump construction is described for example in EP-A 0 025 224.
  • the method can advantageously be carried out by means of a device which is characterized in that the vacuum suction head is designed to actuate the pump up to its end stop and can preferably be pressed by a pneumatic cylinder onto the containers passed by it.
  • a container 11 which is filled with a filling medium 12.
  • a filling medium 12 is a liquid, pasty or gel-like medium, especially for cosmetic or pharmaceutical use, e.g. a gel to be injected into a patient's nose.
  • the invention is particularly suitable for such gels, pastes or highly viscous liquids.
  • a metering or atomizing pump 14 is placed tightly on the mouth 13 of the container, in the example shown by snapping on a pump base part 15 with the interposition of a seal 16.
  • the pump with almost all its details, is made of plastic.
  • the pump has a pump cylinder 17, at the lower end of which a seat 18 for a spherical inlet valve 19 is formed.
  • the inlet channel leading downwards is connected to a flexible suction hose 20 which projects into the container.
  • a piston 21 made of flexible material runs in the pump cylinder 17 and is designed overall as a sleeve-like sleeve, the lower sealing lips 22 of which abut the pump cylinder wall.
  • the valve seat body 24 is pressed into a hollow piston rod 26 and is otherwise surrounded by an upper tubular section of the piston forming an elastic neck 27, the upper end of which is tightly clamped on the piston rod 26.
  • the piston is assembled in such a way that the elastic neck 27 is biased outwards in the rest state with bulging and thus exerts a closing force on the outlet valve formed between the parts 24 and 25.
  • the valve seat body 24 has a plurality of grooves 28 on the outer circumference, which are connected to the rest of the outlet channel 29 formed in the hollow piston rod.
  • a return coil spring 30 acts on the valve seat body 24, which attempts to press the single-acting pump into its rest position and at the same time prevents the spherical outlet valve from entering the pump chamber 31 in an uncontrolled manner.
  • an outer sealing cone 34 of the piston rests against an upper step 35 of the pump cylinder and seals off the pump chamber and in particular an air compensation opening 36 provided in the form of an opening in the pump cylinder wall.
  • the pump is thus completely closed to the outside in the idle state, while in the actuated state an amount of air corresponding to the volume dispensed can flow into the container from the outside.
  • Adjoining the piston rod 26 is an actuating button containing the outlet channel 29, which can also be designed as an interchangeable adapter. Depending on its function, it can have a wide variety of designs and can be provided with straight outlet channels, spray nozzles or the like. In the present case, it is a broken-off, elongated conical adapter with a straight outlet mouth 38, which has a wide step 39 at its pump-proximal end for supporting the fingers when the actuation button is pressed down.
  • the container is accommodated in a device 41 and is positioned in its upright position in relation to a suction head 40 which can be pressed onto the pump from above in the direction of arrow 42.
  • the device is shown in detail in FIGS. 2 and 3.
  • the device 41 is shown in plan view in FIG. 2. It forms a machine that is switched on in a manufacturing process for filling the containers 11 and applying the pumps to them is. The filling and application stations are not shown here.
  • the filled and pumped containers 11 arrive in a conveying channel 43 and are pushed in pairs by a slide 45 actuated by a pneumatic cylinder 44 into two semicircular recesses 46 on the outer circumference of a horizontally arranged, gradually rotatable disk 47 of a rotary table.
  • the disk is surrounded at some distance by a circularly arranged L-profile 48 (FIG. 3), which forms a support and circular guide for the containers 11.
  • the containers are conveyed in pairs with the gradual rotation of the disk 47 in a circle. Numerous, for example twelve pairs of recesses are provided on the disk at a uniform distance, and the stepping drive switches by one division (a twelfth revolution).
  • Two suction heads 40 are arranged on a suction station 40 in order to process the pair of containers simultaneously.
  • a guide column 50 is arranged on the suction station 49, on which the two suction heads 40 are accommodated next to one another on a support 51 which is adjustable in height.
  • Each suction head has at its lower end a cone-shaped receptacle 52 in the example shown for the actuating button in the mouth area (see FIG. 1).
  • This receptacle can be arranged in any way corresponding to the outlet channel openings 38 and the actuating lever shape. It should depress the actuation button and at the same time be able to produce a sealed connection between the outlet channel 29 and the suction head.
  • the suction channel 53 in the suction head 40 is connected via a line 54 to a control device 55, which is shown as a three-way valve and, depending on the overall control of the device, can optionally be connected to a vacuum line 56 or a compressed air line 57.
  • a control device 55 which is shown as a three-way valve and, depending on the overall control of the device, can optionally be connected to a vacuum line 56 or a compressed air line 57.
  • a pneumatic cylinder 58 is actuated by the overall control of the device and moves the suction head 40 up and down.
  • a rail 60 Opposite the suction station 49 there is a rail 60 which engages in the circular guideway 49 for the containers and which removes the containers from the wheel and directs them to a discharge path 61, from where the containers which have now been completed are conveyed for packaging and removal.
  • a different number of containers for example three or four in each case, could also be processed in parallel and / or further processing operations could be carried out on the rotary table, for example sticking labels or the like.
  • the disc 47 places the containers under the respective suction heads 40, and these are moved downward by the pneumatic cylinder 58, so that the receptacle 52, which is optionally provided with a seal, rests on the actuation trigger and presses it down until the one shown in FIG. 1 Position is reached, in which the sealing lips 22, or in another embodiment another part of the piston, come to rest on the step 32 and the outlet valve 25 opens while overcoming the pretension of the elastic neck 27.
  • the suction line 54 is placed on the vacuum line 56, so that a suction effect occurs in the pump chamber 31 via the outlet channel 29, the grooves 28 and the outlet valve 25, which leads to the filling medium 12 via the suction hose 20 and the inlet valve 18, 19 is sucked into the pump chamber.
  • the filling of the pump chamber is completed in a very short time (approx. Two tenths of a second). A further suction of the filling medium through the outlet valve into the outlet channel does not take place, since the vacuum is dimensioned depending on the outlet valve cross section and the viscosity of the medium in such a way that a flow through the outlet valve would take a considerably longer time.
  • the suction head 40 is raised again by actuating the pneumatic cylinder and a very short burst of compressed air is applied to the suction head by switching over the control device 55.
  • the inlet valve 19 is closed with certainty and very quickly by reverse pressurization, and it is ensured with certainty that the actuation button is released from the suction head 40 again.
  • the device works satisfactorily even without the compressed air surge.
  • the pump chamber is now finally filled. 1, only the dead space of the pump was filled, while the actual displacement is only filled during the subsequent automatic upward movement.
  • the air equalization channel which contains the opening 36, is open. It is closed again after the end of the upward stroke by the incline 34 on the step 35.
  • the cycle is time only 0.3 seconds, so that approx. 10000 containers per hour can be processed on the device.
  • FIG. 4 shows a detail of a suction head 40a which, following the sealing receptacle 52a, has a pump cylinder 70 with a single-acting piston 71.
  • the suction head which can be moved up and down as a whole in the manner described above contains an additional pneumatic cylinder 72 which moves the piston rod 73 of the piston 71 up and down.
  • the stroke of the piston 71 is adjustable.
  • the piston delimits in the cylinder a vacuum chamber 76 which is connected to the suction head orifice 75 in the receptacle 52a via an intake duct 74 and which is increased in volume by actuating the pneumatic cylinder 72 after the suction head is pressed onto the mouth of the pump outlet duct , which corresponds approximately to the amount of liquid to be added. So only enough filling medium is sucked into the pump that the desired filling level, for example up to the outlet valve of the pump, is reached.
  • the volume of the vacuum chamber can be increased somewhat in order to achieve the desired level in the pump despite flow resistance and volume changes due to geodetic height differences.
  • the air drawn in is pushed out via the piston.
  • This embodiment ensures that even with very thin liquids that could flow relatively easily through the outlet valve of the pump, the pump is only filled to the desired extent. This also applies to other filling media with a correspondingly large outlet valve cross-section.
  • FIG. 5 shows an embodiment in which the suction head 40b likewise has a cylinder 70 and a piston rod 73 which can be actuated by a pneumatic cylinder 72.
  • the piston 71 is equipped with two sealing lips so that it seals during the upward and downward stroke.
  • a valve 80 is installed in the suction channel 74b and serves as an inlet valve of the pump formed by cylinder 70 and piston 71b.
  • an outflow channel 81 branches off, which merges into a discharge line 83 via a spring-loaded ball valve 82 that opens in the outlet direction.
  • the function is such that the suction is also carried out by an upward movement of the piston 71 b, the stroke of which can be adjusted if necessary.
  • filling media emerges from the pump outlet channel and flows into the vacuum space 76b via the valve 74b, it is transported away via the outlet valve 82 and the discharge line 83 on the return stroke of the piston 71b, which fits into the cylinder with relatively little dead space. In this way it is ensured that, even if excess filling medium is sucked up, it is drained off in a prescribed way and cannot contaminate the containers or the machine.
  • any other type of vacuum chamber can be used, which can change its volume in a targeted manner, for example membranes etc.
  • the actuation can be done in any manner, including mechanically. It could also be connected to the suction head actuation by connecting the stroke of the piston 71, 71 after performing the suction head stroke in order to depress the actuation trigger of the pump. This would save an actuator.
  • the liquid emerging from the discharge line 83 can be returned to the filling station or to a storage container.
  • a separator for entrained filling medium could be installed between the suction head mouth and the vacuum pump or an associated valve, which prevents contamination of the valve or pump. 4 and 5, but also in the other versions, a small dead space between the suction head mouth and the vacuum source is advantageous.
