Definitions

  • the invention relates to a cup filling machine, as has become known in accordance with the preamble of claim 1 by public prior use.
  • the known cup filling machine has a sterile treatment station in the flow downstream both behind the cup feed station and behind the lid feed station.
  • This sterile treatment station is supplied with hydrogen peroxide via a metering device and an atomizing nozzle. It is important here that the hydrogen peroxide is fed to the sterile treatment stations, which work intermittently with the cup filler, in a precisely metered amount.
  • Each metering device of the known cup filling machine has a circular cylindrical sight glass that is sealed between a cover flange and a bottom flange to form a sterile agent container.
  • the hydrogen peroxide is fed through the bottom flange using a continuously operating sterile pump.
  • an electrical filling level control known per se is provided in order to ensure a certain filling level of the hydrogen peroxide within the sterile agent container.
  • a measuring cup is provided in the metering device of the known cup filling machine, which is arranged laterally projecting at the free lower end of a holding rod that can be moved up and down in the working cycle of the cup filling machine.
  • This support rod immerses the measuring cup below the filling level of the hydrogen peroxide, scoops the sterile agent (for example in the manner of a ladle), and then returns the measuring cup vertically to its starting position above the level of the sterile agent. This is done in such a way that the suction tube is immersed in the sterile agent present in the measuring cup.
  • the sterile agent dosed in this way is then sucked off within one working cycle and fed to the atomizing nozzle for transfer to the cups or the lids. This process is repeated with every work cycle.
  • Suction tube and overflow measuring cup of the sterile agent dosing device of the known cup filling unit each represent the electrode of a level control device.
  • level control devices such as those manufactured by the company H. Negele under the name “Niveau réelle gnv-d", are known per se and do not form an object of this invention.
  • the level control ensures, however, that an interfering signal that switches off the cup filler is generated in the event that either the sterile pump does not work or does not work properly, i.e. does not deliver sterile, or that the suction of the sterile via the suction pipe does not work.
  • the Nieveau control device which measures a resistance distance between the two electrodes, would measure a small resistance at one phase of the working cycle and in the other case a very large resistance in the absence of sterile agent in another phase of the working cycle, in any case but trigger an interference signal.
  • a sterile agent dosing device with a much simpler construction is primarily desirable.
  • such a sterile agent dosing device should also offer the possibility, with little additional effort, of quickly changing the dosing amount of sterile agent in adaptation to different container and lid sizes.
  • the sterile agent dosing device of the cup filling unit it is first of all essential that, as long as a certain amount of sterile agent is maintained unchanged, the suction pipe and overflow measuring container are in a defined, spatially fixed relative position to one another, in total spaced from the bottom of the sterile agent container.
  • the sterile medium pump no longer conveys an excess quantity of sterile medium intermittently but rather intermittently through a sterile medium supply line into the overflow measuring container.
  • the metering volume is always constant, while vibrations occur in the known as a result of the mechanical scooping movement - and in the event of improper maintenance can lead to a partial spillage of the sterile from the scoop, that is, to a small amount.
  • the sterile agent supply line is a vertical, in particular free-standing cylindrical riser pipe, to which each overflow measuring container is directly connected to conduct liquid.
  • the overflow measuring container can be connected in two fundamentally different ways:
  • the vertically arranged cylindrical riser pipe has a cylindrical axial extension coaxial with it and directed upwards, which at the same time forms the overflow measuring container.
  • This axial extension is thus filled via the sterile medium pump, which in each working cycle supplies an excess metering quantity, whereupon the suction pipe, which is constantly in the relative position in the axial extension, sucks off as sterile medium until the suction flow is broken off.
  • the metering volume can be changed in a simple manner by either reducing or increasing the immersion depth of the suction tube in the axial extension.
  • the second basic embodiment of the invention is that the vertical riser is orthogonal to its cylinder central axis has running free upper end face, which is followed by a drain surface which extends inclined towards the bottom of the sterile agent container and which in each case delimits the filling opening of at least one overflow measuring container.
  • This embodiment according to the invention allows a plurality of overflow measuring containers in the form of cup-shaped depressions, which are offset with respect to one another in the circumferential angle and which can have either the same or different metering volumes. In the event that the same dosing volume is available, a separate suction pipe can be assigned to each overflow measuring container.
  • FIG. 1 is a schematic side view of a cup filling machine
  • 2 shows a first embodiment of a metering device
  • Fig. 3 shows a second embodiment of a metering device
  • Fig. 4 shows an only schematically shown essential area of a third embodiment.
  • the bucket filler in Fig. 1 is generally designated by the reference number 10.
  • a revolving conveyor chain K with an upper tower O and a lower run U runs over chain stars 11 and 12.
  • the conveyor chain K has cell boards 13 shown schematically in FIG. 1, which are provided with cup receptacles 14 for cup-shaped containers (e.g. plastic cups) 15.
  • cup-shaped containers e.g. plastic cups
  • the direction of conveyance of the cups 15 received in the upper run O is denoted by x.
  • the work stations of the cup filling machine 10 are as follows: 16 puts the cup bar feed, 17 the cup feed station, 18 the sensor for missing or for double cups, 19 the cup disinfection (sterile treatment station) e.g. by hydrogen peroxide, 20 the main dispenser, 21 the cover placement station with cover disinfection (i.e. another sterile treatment Station), 22 the sealing station, 23 the printing unit for applying the expiry date, 24 the tightness control station and finally 25 the cup removal station.
  • the cup filling machine 10 works as a double-step machine, i.e. with double feed, which means that each work station is occupied twice.
  • the feed occurs intermittently in cycles. Accordingly, the higher the working frequency, the shorter the cycle time in which each work station must begin and end the work assigned to it. This also applies to the sterile agent stations of the cup filling unit 10, which achieves a work rate of approximately 33600 cups / h.
  • liquid sterile metering devices shown in FIGS. 2 and 3 are each designated by the reference number 26.
  • a sterile agent container 27 has a sight glass 28, the two end faces between a container bottom 29 and a container lid 30 are clamped in a sealing manner.
  • the container base 29 is made of an electrically insulating material, in particular plastic, while the container cover 30 is made of an electrically conductive material, in particular stainless steel.
  • a sterile medium feed channel (eg for hydrogen peroxide) 31 is acted upon by a sterile medium feed pump, which works intermittently in cycles. So if a certain dosing volume is required, the sterile pump pumps an excess amount in one go, such that it overflows over the free cutting edge 32 of a circular cylindrical tubular extension 33, so that the excess amount flows out to the container bottom 29 and there via a discharge path 57, 58 can be fed to a sterile agent supply container (not shown) for further use. Accordingly, liquid sterile can never accumulate inside the sterile agent container 27, that is to say within the sight glass 28, so that the free cutting edge end edge 32 is always distanced from excess liquid, and also from the container bottom surface 34. This ensures that the excess amount flows freely over the edge 32.
  • a ventilation duct in the cover 30 bears the reference number 59.
  • the axial extension 33 forms the upper free end region of a substantially circular-cylindrical sterile medium riser tube 35.
  • the longitudinal central axes of the riser tube 35 and the axial extension 33 coincide with the vertical L.
  • the sterile medium liquid level within the axial extension 33 closes off with its cutting edge end edge 32.
  • the sterile agent located within the axial extension 33 is sucked off by means of a two-fluid nozzle 36 and a compressed air valve 39 via the suction tube (ejector tube), designated overall by 37.
  • the suction pipe 37 dips vertically from above with an amount a and coaxially with L into the axial extension 33.
  • Sterile agent is now sucked off until the sterile agent suction flow inevitably breaks off at the lower end edge 38 of the suction pipe 37.
  • the predetermined metered amount is discharged, which is passed on to the atomizer nozzle (identified as 36 in total) (two-substance nozzle) and from there to the cups or lids to be treated in the cup disinfection 19 or in the lid placement station 21 (FIG. 1) .
  • G-rings 40 are provided in the outer tube surface below the threaded engagement.
  • This control device is designated purely schematically at 41.
  • the leveling device 41 is electrically connected via an electrical line 42 to a sliding contact pin 43 which contacts the outer circumferential surface of the riser pipe 35 made of conductive material (stainless steel) within an annular groove 44.
  • the end edge 32 thus forms a first electrode.
  • the control device 41 is electrically conductively connected to the electrically conductive suction pipe 37 via a second line 45, so that its lower end edge 38 forms the second electrode.
  • the signal lamp 46 of the control device 41 lights up and the cup filling machine 10 is switched off.
  • the sterile pump does not deliver.
  • the axial extension 33 would not be filled at the beginning of the suction phase, so that the control device 41 would practically measure an infinitely large electrical resistance between 32 and 38. This would in turn cause the signal lamp 46 to light up and the cup filling unit 10 to be switched off.
  • the spatial relative position between the respective overflow measuring container (e.g. axial extension 33) and the suction pipe 37 is unchanged for the respectively set metering volume.
  • the spatial relative position is only changed if the dosing volume is to be changed.
  • the embodiment according to FIG. 3 basically has the same construction and mode of operation (also with regard to the control device 41) as the embodiment according to FIG. 2.
  • the embodiment according to FIG. 3 is, however, different in comparison to FIG. 2 in that the riser pipe 35 also has at its upper free end an upper free end face or end edge 32 that is orthogonal to its cylinder central axis (perpendicular L). However, this end edge 32 is flush with a drain surface 47, which extends inclined in the direction of the bottom of the sterile medium container 29 and which receives the inlet opening of cup-like depressions 48, 49 of different sizes. These cup-like depressions 48, 49 accordingly form the overflow measuring container for the sterile agent.
  • a plurality of cup-shaped depressions of the type of depressions 48, 49 are arranged here approximately in the manner of a turret with the same radial distance from L in the drainage surface 47, which forms part of an approximately mushroom-shaped body 50.
  • the drainage surface 47 represents a truncated cone.
  • the body 50 is rotationally symmetrical.
  • the suction pipe 37 is cranked outwards.
  • the lower region of the suction pipe 37 with its lower end edge 38 plunges into the receiving volume of the corresponding cup-shaped depression, in the present case in FIG. 49.
  • the sterile agent suction process is otherwise the same as that described in connection with the exemplary embodiment according to FIG. 2.
  • the riser pipe 35 is according to FIG. 2 in its axial area passing through the container bottom 29 non-threaded, rotatable and axially adjustable. If the cup-shaped recess 48 is to be put into alignment with the riser pipe 37 with a larger metering volume, the riser pipe 35 is pulled axially in the direction z by means of a handle 51 arranged at the end and rotated around L until the one previously located in the locking hole 52 spring-loaded locking ball 53 is aligned with the diametrically opposite locking hole 54, whereupon the riser 35 is moved back against the direction z. This backward movement is supported by a helical compression spring 55, which is supported on the underside on the container bottom 34 and on the top side on a support flange 56 on the riser tube side.
  • the mushroom-shaped body 50 in contrast to FIG. 3, essentially only the mushroom-shaped body 50 is shown in another embodiment.
  • the sterile agent container 27 is otherwise also designed as in the embodiment according to FIG. 2, with the difference, however, that according to FIG. 4 two or more suction pipes 37 are provided.
  • Each suction pipe 37 is provided with its own electrical connection (shown schematically in each case), each of which leads via a separate line 45 'or 45' to the control device 41, since the filling monitoring in the cup-shaped depressions 48, 49 is to be carried out separately for the following reasons: 4 is intended, if possible to supply each row of buckets in a multi-lane bucket filler separately with sterile agents. For this reason, the volumes of the cup-shaped depressions 48, 49 within the mushroom-shaped body 50 are each of the same size. Each metered amount within the recesses 48, 49 must therefore be monitored separately.
  • the container lid 30 is due to the different electrical leads 45; and 45 ⁇ made of electrically insulating material (plastic).
