Definitions

  • the invention relates to a method for coating containers made of plastic.
  • Plastics can be used to make containers. However, these plastics can be gas-permeable, so that the later contents of the containers produced can come into contact with gases from the air. In particular, when the containers are filled with food, contact with air should be avoided in order to increase the shelf life of the food.
  • z. B. DE 10 2018 132 609 A1 discloses providing the containers with a barrier layer.
  • the barrier layer is applied to the containers by means of a plasma treatment.
  • the plasma treatment is carried out by means of a container plasma treatment apparatus having a plurality of treatment stations arranged on the circumference of a rotating wheel. With the rotating wheel, the treatment stations are guided one after the other to a loading station, which places one or more containers in a treatment station. Thereafter, the loaded station is connected to a vacuum device to create a vacuum in the container interior. The volume outside the container is evacuated almost simultaneously in the loaded station.
  • the sequence ensures that while the container in the stations is being pumped out, no other station and the containers located therein are connected to the vacuum device. This is followed by the plasma treatment of the container or containers. After the plasma treatment, the station and the container(s) located therein are ventilated and removed from the treatment station at an unloading station.
  • the object of the invention is to provide a method and a device for coating containers made of plastic, which have increased efficiency.
  • the invention provides that at least two of the treatment devices are combined to form at least one treatment group and the at least one pump device evacuates all containers of the at least one treatment group synchronously.
  • treatment facilities are combined into a treatment group.
  • the treatment group can also be referred to, for example, as a network, logical treatment device or virtual treatment device. All treatment devices of the treatment group are connected to a pump device in a fluid-communicating manner and simultaneously or synchronously evacuated by the pumping device.
  • the containers connected to the pumping device thus have essentially the same pressure during evacuation, so that backflows between the containers, which are then connected to one another in fluid communication at least via the pumping device, can be avoided.
  • the evacuation times of the evacuated containers of the treatment group can be combined at least partially in this way. If e.g. B. two treatment facilities are combined into one treatment group, the evacuation time of the containers can be doubled, for example.
  • the evacuation time does not necessarily have to scale with the number of combined treatment facilities.
  • the evacuation times of the individual treatment facilities of the treatment group are lengthened compared to evacuation that does not overlap in time. Due to the extended evacuation time, comparatively reduced end pressures can be achieved with the pump device despite the increased volume to be evacuated.
  • a reduction in the final pressure in the area outside around the container inside the treatment device for the subsequent plasma treatment is advantageous in order to prevent the container from collapsing in the treatment device.
  • the efficiency of the evacuation is increased by combining the treatment facilities in the treatment group and the resulting increased evacuation time. In particular, the efficiency of already existing devices for coating containers can be increased by the method.
  • the treatment group can remain in place for the plasma treatment or be dissolved beforehand.
  • the treatment group can continue to exist until the containers are unloaded from the treatment facilities of the treatment group.
  • the treatment devices can be permanently combined into treatment groups and all sequences in the process for coating containers made of plastic can run through synchronously.
  • the at least two treatment devices can be divided into at least two first groups before being combined into the treatment group, with at least one second pump device being able to synchronously evacuate the container of at least one of the at least two first groups.
  • the first groups can thus have a number of treatment devices that differs from the number of treatment devices in the treatment group formed later.
  • the number of treatment facilities in a first group can be larger or smaller ner than the number of treatment facilities in the treatment group.
  • the at least one pump device and the at least one second pump device can also represent different pump stages, with the containers being evacuated in stages to the pressure required for the coating.
  • the at least one second pump device can initially evacuate the container to a first intermediate pressure level that is higher than the pressure level that can be achieved with the at least one pump device.
  • the at least one pump device starts evacuating the containers at the first intermediate pressure level.
  • the at least one second pump device can initially evacuate at least one first group synchronously to the intermediate pressure level before this first group becomes part of a treatment group, which is then evacuated by the at least one pump device. It is very advantageous if this first group is only combined with other treatment devices in the treatment group that were evacuated to the same pressure level. The flexibility of the procedure is increased by the division into first groups before combining them into the treatment groups.
  • the treatment group can be divided into at least two second groups after evacuation by the at least one pump device and at least one third pump device evacuates the containers of at least one of the at least two second groups synchronously.
  • the second groups can thus have a number of treatment devices that differs from the number of treatment devices in the previously formed treatment group.
  • the number of treatment devices in a second group can be greater or less than the number of treatment devices in the treatment group.
  • the at least one pump device and the at least one third pump device can also represent different pump stages, with the containers being evacuated in stages to the pressure required for the coating.
  • the at least one pumping device can evacuate the container to a second intermediate pressure level, which is higher than the pressure level with which the at least one third pumping device can be achieved.
  • the at least one third pump device begins the evacuation of the containers at the second intermediate pressure level and further reduces the pressure in the containers of at least one second group.
  • the flexibility of the method is further increased by the division into second groups after the evacuation of the treatment group by the at least one pump device.
  • the treatment group can be dissolved after all pump devices have successively evacuated the containers of the treatment group synchronously.
  • the treatment devices of the treatment group cannot be synchronously evacuated in further pump stages, not synchronously supplied to a plasma treatment and/or not synchronously discharged.
  • the device can also have at least four treatment devices, for example, with the treatment devices being divided into at least two treatment groups each with at least two treatment devices, with the at least one pump device evacuating the treatment groups one after the other.
  • the treatment devices can be moved, for example, one after the other along a closed transport path, with the treatment devices receiving a container at a loading position of the transport path and treated containers being removed from the treatment device at an unloading position of the transport path, with at least two immediately consecutive treatment devices at least on the transport from the loading position to the unloading position are at least temporarily combined to form a treatment group.
  • the treatment devices can thus be combined into treatment groups at any time between the loading position and the unloading position. Furthermore, the treatment groups can be broken up at any time between the loading position and the removal position.
  • a closed transport path is understood to mean a transport path whose end point lies on its starting point. The treatment devices therefore run through the transport path again and again.
  • the treatment facilities z. B. be arranged on the circumference of a rotating wheel.
  • each treatment device can be connected to each pump device by means of at least one valve, with the corresponding valves of the treatment devices of the treatment group being able to be opened synchronously for the fluid-communicating connection of the treatment group to one of the pump devices.
  • Each treatment facility can B. have a dedicated valve for each pump device.
  • the opening of a valve connects the interior of a container placed in the treatment device with the pump device. If, for example, there are three pump devices, each treatment device can have three valves.
  • each treatment device can, for example, additionally have at least one further valve that is connected for fluid communication within the treatment device to the area outside the inserted container.
  • the at least one further valve can also be connected in a fluid-communicating manner to one of the pump devices or to a further pump device.
  • the invention also relates to a device for coating containers made of plastic, the device having at least two treatment devices for the containers and at least one pumping device for evacuating containers that are placed in the treatment devices, with a container placed in a treatment device being pumped through the at least a pump device is evacuated, the device having a control device which is used to combine at least two treatment devices into at least one treatment group and to control a synchronous evacuation of all containers of the at least a treatment group is formed by means of the at least one pump device.
