Definitions

  • the present invention relates to a cleaning device for pharmaceutical containers, comprising means for introducing the containers into the cleaning device and means for discharging the containers from the cleaning device, a transport device for transporting the pharmaceutical containers within the cleaning device and at least one holder for holding at least one pharmaceutical container during a cleaning process in such a way that a respective longitudinal axis of the pharmaceutical containers extends essentially in the vertical direction.
  • the cleaning device comprises at least one cleaning station for cleaning the pharmaceutical container, comprising at least one essentially cylindrical ring nozzle, which is designed to pharmaceutical container during a cleaning process and is provided on its inside with a circumferential row of outlet openings at a first vertical position, which are set up and arranged to discharge a cleaning medium inwards in a substantially identical manner, at an angle to the horizontal downward and at an angle to a radial direction so as to form a cyclone of cleaning medium.
  • the term “cyclone” is to be understood here in such a way that the cleaning medium is directed downwards in a turbulent manner in order to flow around the container to be cleaned in a clockwise or anti-clockwise rotation.
  • the creation of such a cyclone minimizes the occurrence of splashing water, in particular in the vertical upward direction, since an optimized flow of the cleaning medium downward and along the circumference of the container is achieved.
  • the alignment of the outlet openings acting as nozzles can in particular be such that the angle relative to the radial direction is adjusted depending on the shape and circumference of the pharmaceutical container in such a way that a substantially tangential direction of the resulting jet of cleaning medium is achieved on the surface of the corresponding container which further aids in minimizing spatter.
  • the cleaning performance to be achieved is also optimized by the special arrangement and orientation of the outlet openings and the cleaning medium jets generated as a result, so that the effect of mechanical brushes can be achieved or even exceeded in many scenarios.
  • the ring nozzle can also comprise a second row of outlet openings at a second vertical position, which is above the first position is located, wherein the outlet openings of the second row are also set up and arranged to release a cleaning medium in a substantially identical manner inwards, at an angle to the horizontal downwards and at an angle to a radial direction in order to discharge a cyclone in the top described manner, wherein preferably the angle to the horizontal in the second row of outlet openings is greater than in the first row of outlet openings and / or preferably about 30 °.
  • This design of the ring nozzle as a double ring nozzle can produce a high mechanical cleaning effect through the jet of cleaning medium from the first row of outlet openings, which impinges on the object surface at an obtuse angle, with an optimal angular alignment against the radial direction in the manner described above, while on the other hand, the development of spatter is minimized, in particular in the upward direction, in that a downward direction is increasingly specified in the outflowing cleaning medium by the second jet ring which forms a cyclone and has a steeper angular orientation.
  • the cleaning efficiency of the process on the outer surfaces of the pharmaceutical containers is improved, while upward splashes are reduced to a minimum.
  • the required medium pressure of the cleaning medium can be increased at the same time by supplementing the cleaning medium from the first row of outlet openings, which impinges at a flat angle with respect to the container to be cleaned, by providing the additional cleaning medium can be reduced via the second, the flow direction favoring jet ring for an optimal cleaning effect.
  • outlet openings of the first row and the outlet openings of the second row are each designed to discharge the cleaning medium at an angle on the same side with respect to the radial direction , so as to form co-rotating cyclones which, by the nature of their interaction with each other, tend to be less likely to form spatter.
  • ring nozzles can of course be installed and operated individually, it makes sense to provide at least one pair of ring nozzles, which are carried in a substantially symmetrical manner on a common bracket, with a supply channel for cleaning medium to the two ring nozzles being provided within the bracket is.
  • a ring channel running around the ring nozzle can be provided for the transport of cleaning medium, via which the outlet openings are supplied in each case, the transition between the supply channel and each of the ring channels being via a connection
  • a blind hole, and with respect to the direction of extension of the holder oblique bores is made.
  • the flow of cleaning medium to the outlet openings is accomplished in an optimized and as laminar manner as possible, which reduces turbulence losses and thus enables the cleaning medium to be supplied at a reduced pressure. Furthermore, the optimized media flow optimizes the uniform and repeatable cleaning of the containers. Furthermore, the outlet openings are supplied essentially at the same time, so that they form the jets and thus the cyclone quickly and evenly.
  • the design of the cleaning device according to the invention just described also allows it to be operated in a low-pressure range in any case. for example down to 0.5 bar.
  • operation in a high-pressure range of at least up to 3.5 bar is also possible without any problems, provided that the type of soiling of the pharmaceutical containers should require this.
  • At least one flat seal can be provided for sealing the at least one ring nozzle, which can be provided, for example, in the area of the nozzle rings and bore closures.
  • a drying station can be included in the cleaning device according to the invention, which is connected downstream of the cleaning station with regard to the transport device, and preferably at least one annular drying unit, which is designed to completely surround one of the pharmaceutical containers during a drying process.
  • This drying station can also be provided in the manner already described above for generating at least one cyclone with correspondingly arranged outlet openings for a gaseous drying medium and can also comprise drying units arranged in pairs and a corresponding supply of drying medium in a single holder in the manner described above .

  • the container to be cleaned and/or dried is first moved by the transport device to a position provided for this purpose, whereupon the ring nozzle or the ring-shaped drying unit is then moved along its vertical extent in order to remove dirt from a large area or to dry it of the container to allow.
  • the annular nozzle and/or the drying unit can be slipped over the container to be cleaned or dried and held from above from vertically below, while in other embodiments, however, the annular nozzle and/or the annular drying unit could also be conceivable, for example by means of two half-shells, which are moved up to the side of the transported container in a cleaning configuration in order to completely surround it during the cleaning or drying process.
  • the corresponding pharmaceutical containers to be cleaned are often transported in such a way that their closure points upwards in the vertical direction, it can therefore be advisable to design the at least one holder for the corresponding containers as a gripper and to assign it to the transport device, with the gripper being set up for this purpose is to support the at least one pharmaceutical container at its top.
  • the corresponding gripper can optionally be set up for gripping vials, ampoules and/or carpules, wherein in a cleaning device according to the invention a quick and efficient conversion from one container type to the other can be made possible simply by replacing or modifying the corresponding gripper.

  • the gripping portion is arranged in such a way that it grips the container in a sealed manner, so that the aforementioned accommodation space is sealed off from the environment in the gripped state of the container, in which case preferably further Means for loading the receiving space with a gaseous medium can be provided with an increased pressure. As a result, a further safety measure is then taken, which reliably prevents the ingress of splashes or other contaminants into the area of the head section of the container during a cleaning and/or drying process.
  • At least one height-adjustable carrying device which is designed to carry the corresponding pharmaceutical container below one of the ring nozzles or one of the ring-shaped drying units, so that the carrying device additionally or alternatively can be used to the gripping portion.
  • the cleaning device according to the invention can comprise a blow-off station, which is downstream of the cleaning station with regard to the transport device and is optionally arranged between the cleaning station and the drying station, the blow-off station being set up to blow off the holders assigned to the transport device by means of at least one air curtain, for example by means of two air curtains at an angle to each other.
  • the provision of such a blow-off station can prevent water from being carried over, particularly in embodiments of the present invention in which high media pressures are used in the cleaning station, which can lead to increased spatter formation and wetting of the holders.
  • the air curtain can be formed by any suitable nozzle arrangement that is supplied with compressed air.
  • the cleaning device can implement an empty part compensation, with an empty part detection unit assigned to the means for inserting the containers is provided, which is set up to detect that there is no container at an input position of the means for inputting the containers but rather an empty space, and wherein the transport device is also set up to, if there is an empty space in a transfer area between the means for inputting the Container and the transport device to hold back the next holder until another container is entered by the means for inputting the container into the transfer area.
  • This vacancy compensation ensures that each of the holders always carries a container during operation and spray water is prevented from being carried over to unoccupied holders.
  • the transport device can be set up to be operable in a start-up mode in which all of the holders are moved out of the area of the cleaning station and possibly the drying station when the cleaning device is started up. In this way, it can be prevented that undesirable operating states occur during start-up of the device, during which media lines have to be filled with cleaning medium, which could lead to spray water being carried over.
  • the cleaning device can also be set up to be operable in a cleaning repeat mode in which, in the event of a malfunction in the cleaning station and/or the drying station, containers that have already been handled in the corresponding station are subjected to a new treatment.

  • the embodiment of a gripper 400 shown in FIG. 6 again has two half parts 402 and 404 in its upper area, which together form a gripping area 406, as well as a height-adjustable carrying device 408 as an external component, which is designed to hold the ampoule B3 from below to carry.
  • the corresponding cleaning process of the ampoule B3 now takes place in such a way that after the ampoule B3 has been moved into its intended position in the area of the ring nozzle 100, the carrying device 408 is initially moved vertically upwards until the ampoule B3 is thereby in the area of its Bottom B3c is worn, while at the same time the ring nozzle 100 is brought into an upper position.
  • the two half-parts 402 and 404 of the gripper 400 are then opened, so that the skewer area B3a of the ampoule B3 is released.
  • the holding device 408 is then moved to a lower position together with the ampoule B3 and the annular nozzle 100 begins its cleaning process in the manner described above. Since the holding device 408 moves the ampoule B3 back into its upper position during the operation of the ring nozzle 100 , the spike B3a and then the cylindrical section B3b of the ampoule are successively cleaned from the nozzle 100 .
  • the two half-parts 402 and 404 now close again and the ampoule B3 is held by the gripping section 406 in the area of its spike B3a, while the carrying device 408 moves vertically downwards together with the annular nozzle 100 and thus the rest of the cylinder section B3b departs and cleans.
  • the bottom of the ampoule B3 can be cleaned in this step by a nozzle 410 integrated into the carrying device 408 . Both the carrying device 408 and the nozzle 100 are then lowered far enough for the ampoule B3 to be transported further by means of the transport device 16 .
  • FIG. 7 now shows a possible embodiment of the blow-off station 25 from FIG. 1 in three views from the side (top left view), from the front (top right view) and from above (bottom view).
  • two blow-off units 25a and 25b are provided, which each use a plurality of compressed air nozzles to generate a corresponding air curtain VA and VB, which are at an angle to one another and through which the gripper 18 is guided by means of the transport device 16 in order to blow off.
  • the blow-off station has the task of blowing off medium adhering to the gripper 18 , in particular after the container has been cleaned in the cleaning station 24 with cleaning medium under high pressure. In this way, despite the expected increase in spatter formation, it is possible to reliably prevent the medium from being carried over to downstream system components by wetting the grippers 18 .
