Definitions

  • the present invention relates to a device for filling nested containers, with the containers being arranged in at least one row in a nest and being conveyable by means of a conveyor device, with a filling station for simultaneously filling the containers in a row, with at least one weighing station for weighing a row of the Packs, with a first gripping device for the simultaneous removal of a row of packs to be filled and for transferring these packs to a first weighing station of the at least one weighing station and for transferring the weighed packs from the at least one weighing station back into the nest from which the first Gripping device has removed the row of containers to be filled, or back into a subsequent nest.
  • containers are preferably to be understood as meaning pharmaceutical or cosmetic objects such as syringes, vials, cylinder ampoules, etc.
  • the conveying device preferably defines a transport direction, in which case “in front of” or “behind” or “after” is to be understood in relation to this transport direction.
  • Such a device for filling is preferably arranged within a production line, with the containers being prepared for filling in one or more previous steps, i.e. for example unpacked and arranged in nests and/or sterilized and/or heated or cooled in order to fill the containers not to affect the filling product.
  • a device for closing the filled container is preferably connected downstream of the device for filling in the direction of transport. The bundles can then be packed individually or in groups, preferably sterile, for onward transport to an end user.
  • Such a device is for example from the document DE 103 45 338 B4 known, with a transport system transporting the nested containers in cycles, with a gripping device removing a row of containers to be filled from a nest and transferring them to a weighing station, with the gripping device transferring the weighed containers to a filling station after weighing, with this row then being filled. After filling, the gripping device transfers this row to the same weighing station a second time, whereby the row of filled containers is weighed again and their net content is thereby determined, and the filled row is put back into the nest and is let out when filling the nest, by one to avoid double filling.
  • this control can be carried out during the ongoing filling process.
  • this measurement often leads to delays in the filling process, since it takes a certain amount of time to determine the net content of the container.
  • the filling process must be at least partially interrupted in order to remove the row of packs, weigh them, feed them to the filling station and fill them, weigh them again and put them back in the nest.
  • the filling process of the checked containers differs from the filling process of the other containers. It is therefore not possible to really check the filling process as it is carried out in normal operation. In the worst case, incorrect alignment of the filling station with a row of a nest to be filled can result in the product being poured off the line. Such an error cannot be detected with the above method.
  • From the DE 10 2004 035 061 A1 discloses a device for dosed filling of vessels located in groups in receptacles on a carrier plate, which has a weighing device for checking the dosing results of a dosing device, wherein the weighing device has a lifting mechanism for lifting at least one of the vessels from a seat of the carrier plate, wherein the weighing device has a lifting mechanism so that the individual vessels only have to be lifted out of the nest in order to be weighed.
  • the same weighing device is used before and after the individual vessels are filled, so that a nest must be within reach of the weighing device before and after filling.
  • the transport device must be stopped when the container is being weighed and the weighing device must be at a standstill for a short time. A checkweighing is therefore always accompanied by a delay in the filling station.
  • the objects are not filled in the nests, but must also be removed for filling, which leads to longer processing times.
  • the filling machine comprises: a handling device, a weighing device, a first filling device and a second filling device, the first filling device being set up to fill containers arranged on the weighing device. Furthermore, the second filling device is set up to fill containers arranged in a nest.
  • the handling device contained is set up to bring individual containers and/or rows of containers from the nest to the weighing device. In addition, the handling device can remove the containers from the weighing device and put them back into the nest.
  • the containers are filled during weighing, which results in complicated control of the filling system and long processing times.
  • a device for weighing a container with at least one weighing device for weighing at least one container, at least one container receptacle for transporting the container relative to the weighing device, with at least one drive surface and at least one mover that can be coupled to the drive surface being provided, with the mover on the Drive surface is arranged to be displaceable and/or rotatable in at least two degrees of freedom and the receptacle holder is arranged on the mover.
  • a device for filling nested containers, with the containers being arranged in at least one row in a nest and being conveyable by means of a conveyor device, with a filling station for simultaneously filling the containers in a row, with at least one weighing station for weighing a row of the containers , with a first gripping device for the simultaneous removal of a row of packs to be filled and for transferring these packs to a first weighing station of the at least one weighing station and for transferring the weighed packs from the at least one weighing station back into the nest back into the nest from which the first gripping device has removed the row of containers to be filled, or back into a subsequent nest, with a second gripping device for the simultaneous removal of a row of filled and weighed containers and for transferring this row of containers to the first weighing station or to a second weighing station of at least e inen weighing station and for transferring the row of filled and twice weighed containers from the at least one weighing station back to the nest from which the second gripping device has removed the row of
  • the device and the method make it possible to carry out an in-process control without interfering with the ongoing operation.
  • the filling system preferably continues to run at normal speed.
  • At least 6% and in particular at least 10% of the packs can be checked in this way, but it is also conceivable to check more, all or fewer packs.
  • the first and the second gripping device are preferably constructed essentially identically.
  • the first and/or the second gripping device can be designed according to the container to be weighed. It is conceivable that the first and/or the second gripping device has a lifting device that lifts the containers that protrude from the bottom of the nests, so that the gripping device can grip the raised containers, preferably by means of gripping tongs.
  • suction cups are also conceivable to provide a gripping device with suction cups, with the suction cups being able to be arranged on a smooth surface of the container in order to temporarily fix the container on the gripping device by means of negative pressure.
  • a transport device is understood to mean any possible type of device that is suitable for transporting nested containers. It is conceivable that clusters of containers lie on two parallel conveyor rails and are thus conveyed. It is also conceivable to use the nests in a rail provided for this purpose, or to accommodate the nests in a transport carriage. Furthermore, it is possible to transport the nests of containers by means of a conveyor belt or to transport them clamped between at least two conveyor belts.
  • a nest is to be understood as meaning any type of device or arrangement that is suitable for combining a number of bundles.
  • the containers are preferably arranged in several rows.
  • a row can consist of at least two bundles.
  • a weighing station according to the present invention can be any type of weighing device that makes it possible to weigh several packages individually and essentially in parallel.
  • the filling device has a control unit that is designed to control the first and the second gripping device and the at least one weighing station and to weigh at least 6% of the packs in a nest.
  • a control unit that is designed to control the first and the second gripping device and the at least one weighing station and to weigh at least 6% of the packs in a nest.
  • This enables a high quality standard to be achieved.
  • at least 10% or exactly 10% of the containers in a nest can be weighed.
  • An example list of different nest configurations can be found in the following table. bundles per nest number per row Proportion of a row of total bundles of a nest [%] 160 16 10 10 6.25 100 10 10 64 8th 12.5 48 8th 16.67 6 12.5 ... ... ...
  • a row of bundles preferably has exactly 6.25%, 10%, 12.5% or 16.67% of the bundles of a nest. Consequently, exactly 6.25%, 10%, 12.5% or 16.67% of the packs in a nest can be grasped and weighed using the gripping devices.
  • a row has exactly 10 packs, with the first gripping device and/or the second gripping device being designed to grip 10 packs at the same time.
  • the speed of the filling system can be further improved
  • the filling station has a plurality of filling points perpendicular to a conveying direction of the nested packs, the number of packs in a row corresponding to the number of filling points of the filling station.
  • both the first gripping device and the second gripping device can be designed in such a way that they each grip the entire row of packs at the same time.
  • the row of nested containers extends perpendicularly to a conveying direction of the nest.
  • the first gripping device is preferably designed in such a way that it can put the container back into or into the nest before or at the filling station. This can ensure that the filling process is not disturbed, so the filling device can continue to run at normal speed regardless of the measurement. Due to the fact that no interruption is necessary for the measurement, the filling device can generally run faster. This enables a consistent processing process, so that greater accuracy can be achieved. In particular, the process times of the system remain essentially the same, so that further process steps such as gassing the containers can be carried out without being affected by the weighing process.
  • the second gripping device is designed in such a way that, before the second weighing, it removes the packs from a nest behind the filling station, i.e. preferably between the filling station and a closing station, and after the second weighing, the packs are placed in a nest or behind the nest the filling station and preferably in front of the capping station. This ensures an uninterrupted filling process.
  • the first weighing station and/or the second weighing station have a plurality of weighing cells, the number of weighing cells preferably corresponding at least to the number of containers to be weighed, with the containers being able to be weighed individually at the same time. This enables all containers to be weighed to be weighed quickly, with the speed at which the system runs preferably essentially depending on the speed of the filling station and is not affected by the weighing.
  • the first gripping device and/or the second gripping device has an at least two-axis gripper.
  • the filling device can be implemented in a structurally simple and cost-efficient manner.
  • simple control of the first gripping device and/or the second gripping device and short transport times for the container to be weighed are possible.
  • the first gripping device and/or the second gripping device is designed in such a way that it can remove packs, preferably a whole row of packs, from several, in particular all, positions of the nest and move this or one position to this or another position other Nestes can reset.
  • This enables a very dynamic construction of the system.
  • the system can continue to be driven during weighing, since the row can also be reset independently of the position of the nest.
  • first gripping device and/or the second gripping device has gripping tongs with two clamping strips in order to clamp a row of containers. In this way, a removal of a number of containers can be achieved in a structurally simple manner.
  • the net content of each individual container is determined from the result of the first weighing and the result of the second weighing, with the filling station being adjusted individually taking into account the determined net content of each container.
  • filling the container and closing the container are to be understood here in such a way that filling or closing including gassing of the container can also be included.
  • the Fig.1 shows schematically a filling device 10 in a production line for filling nests 12 of containers 14, which for reasons of clarity in 1 are not shown further.
  • the nests 12 are transported in the direction of the arrow by a transport device 16, which is symbolized in simplified form by arrows.
  • the filling device 10 has, shown schematically, a first gripping device 18 and a second gripping device 20, each of which has a swivel arm 22 and gripping tongs 24.
  • the filling device 10 has a filling station 26 and at least one weighing station 28 with weighing cells 30 that are not shown in detail.
  • a closing station 32 for closing the containers 14 is arranged downstream of the filling device 10 in the transport direction, which is preferably followed by a packaging station 34 in which the containers 14 can be removed from the nests 12 and packed in appropriate containers, such as cartons, for onward transport . It goes without saying that the bundles 14 can also remain in the nests 12 and can be packed together with the nests 12 .
  • An upstream device 38 can be provided upstream of the filling device 10 in the transport direction, in which the containers 14 are prepared for filling, i.e., for example, unpacked and arranged in the nests 12 and/or sterilized and/or heated or cooled in order to fill the containers 14 not to affect the product to be filled.
  • the Figure 2a 12 shows an embodiment of a filling device 10.
  • Nests 12 of containers 14 are fed to the filling device 10 by means of a conveying device or transport device 16.
  • the filling device 10 also has a first gripping device 18 and a second gripping device 20 .
  • the first gripping device 18 and the second gripping device 20 have essentially the same construction, so that only the first gripping device 18 is described in more detail below.
  • the movement radii of the gripping devices are shown schematically as circles.
  • the first gripping device 18 has a swivel arm 22 on which gripping tongs 24 which can in turn be swiveled are arranged.
  • the first gripping device 18 is arranged in front of a filling station 26 in the conveying direction.
  • a weighing station 28 is arranged in the conveying direction between the first gripping device 18 and the second gripping device 20 .
  • the weighing station 28 has individual weighing cells 30 .

  • the first gripping device 18 is used to remove a row of packs 14 from a nest 12 and to transfer them to the weighing station 28, with each weighing cell 30 of the weighing station 28 preferably being assigned a pack 14, so that the packs 14 are weighed essentially in parallel and individually. After weighing, the packs 14 are picked up again by the first gripping device 18 and put back into the nest 12 . The empty weight of the individual containers 14 can be registered here.

  • a row of packs 14 corresponds to less than 10% and in particular less than 6% of the packs 14 in a nest 12, with at least as many rows of packs 14 in a nest 12 before and after are weighed during filling, so that at least the desired proportion of the containers 14 in a nest 12 are weighed before and after filling.
  • the number of containers 14 removed preferably corresponds to the number of filling points in the filling station 26, so that a complete filling cycle can be checked. Consequently, the influence of filling points on one another can be checked or ruled out.
  • each row of a first nest 12 is preferably weighed so that the system can be taught in quickly. The system can be put into operation with little time and loss of product.
  • each row of the last nest 12 and possibly the penultimate nest 12 is preferably weighed so that it can be checked up to which row and in particular up to which container 14 of a row the required fill level is reached. This minimizes the loss of product when the system runs empty.
