Definitions

  • the invention relates to a treatment station and a device for treating containers.
  • Methods and devices for carrying out a filling process are known, in which a container to be filled is sealed with a treatment chamber, a filling valve is connected to the mouth of the container to be filled and the interior of the container to be filled is flushed with a flushing gas to reduce the oxygen content. After flushing the interior of the container with the flushing gas, the interior of the container is then filled with the filling product.
  • the container to be filled can also be pre-stressed or evacuated.
  • the treatment chamber Simultaneously with the filling of the interior of the container with the filling product, either before or after, the treatment chamber is brought to an overpressure and the filling valve is then removed from the mouth of the container that has already been filled with the filling product. Due to the excess pressure present in the treatment chamber, when the filling valve is removed from the mouth of the container filled with the filling product, overflowing, splashing out or foaming, in particular from a carbonized filling product, is reduced or completely avoided. In this phase, the treatment chamber, which is under excess pressure, communicates accordingly with the interior of the container filled with the filling product.
  • a container closure is then applied to the container in the treatment chamber, which is still under excess pressure, and the container is closed accordingly. Subsequently, the excess pressure present in the treatment chamber is essentially reduced to ambient pressure and the filled and closed container is then removed from the treatment chamber.
  • a container closure is then applied to the container in the treatment chamber, which is still under excess pressure, and the container is closed accordingly. Subsequently, the excess pressure present in the treatment chamber is essentially reduced to ambient pressure and the filled and closed container is then removed from the treatment chamber.
  • the WO 2019/048661 A1 relates to a positioning device for the relative positioning of a container to be treated and a treatment element in a container treatment system, comprising a positioning cylinder and a piston accommodated in the positioning cylinder, which is connected to a piston rod.
  • a pressure chamber is formed between the piston and the positioning cylinder, which can be acted upon by a working medium.
  • a locking mechanism for locking the position of the positioning cylinder relative to the piston rod is received in the piston rod.
  • a first control cam is required for the controlled movement of the lifting cylinder, a second control cam for unlocking the system and a complex lifting cylinder and bottle suspension, in which the lifting cylinder can also be mounted in a distorted manner, which in turn can lead to a deteriorated lifting movement.
  • assembling the lifting cylinder can be comparatively complex
  • the invention is based on the object of creating an improved technology for a lifting device of a treatment station for filling and closing containers.
  • the technology should preferably be low-wear and enable high acceleration rates with a comparatively small installation space and comparatively low costs.
  • One aspect of the present disclosure relates to a treatment station for an apparatus (e.g., filler-sealer) for treating containers.
  • the treatment station has a filling element for filling a container positioned in the treatment station, a closing element for closing the container positioned in the treatment station and a lifting device.
  • the lifting device has a hydraulic actuator (e.g. hydraulic cylinder) for raising and lowering the container and a directional valve, preferably a 4/3-way valve, for controlling an inlet to the hydraulic actuator and a return from the hydraulic actuator.
  • the hydraulic actuator for raising and lowering the containers can enable very high acceleration rates in a small installation space, which, for example, makes a particularly compact overall system possible.
  • the use of the directional control valve enables the hydraulic actuator to be operated without mechanical control curves.
  • the hydraulic actuator can also be integrated Lubrication must be particularly low-wear, e.g. B. in comparison to mechanical roller controls.
  • the vertical movement of the container can be positioned very precisely (e.g. ⁇ 0.2 mm) and very quickly as desired using the lifting device. Due to the flexibility of the adjustability of the hydraulic actuator using the directional control valve, the number of variants can be advantageously reduced for different formats and machines.
  • the directional control valve can be integrated in the hydraulic actuator.
  • the lifting device can be free of a mechanical control cam and/or a roller or can have no operative connection to a mechanical control cam and/or a roller.
  • the lifting device can have a support plate for supporting the container on the bottom, the support plate being able to be raised and lowered by the hydraulic actuator.
  • the hydraulic actuator can preferably be arranged below the support plate.
  • the hydraulic actuator can have a hydraulic piston that supports the support plate, preferably directly at an upper end of the hydraulic piston.
  • the treatment station has a treatment chamber (e.g. which can be pressurized) in which an upper section of the container with a container mouth can be received for filling by means of the filling element and for closing by means of the closing element.
  • the container can be inserted into the treatment chamber and moved out of the treatment chamber by means of the lifting device.
  • the treatment chamber with the upper section of the container positioned therein can be sealed, preferably on the top side by means of a sealing head of the closing element and/or on the bottom side by means of a seal to the container, preferably the container neck.
  • a position sensor preferably an absolute position sensor
  • the absolute position sensor can be ready for operation immediately after switching on the filler, since no referencing is required.
  • the absolute position sensor can advantageously enable reliable querying of the position even in the event of a previous power failure.
  • the position sensor can be integrated in the hydraulic actuator.
  • control device can refer to electronics (e.g. designed as a driver circuit or with microprocessor(s) and data memory) and/or a mechanical, pneumatic and/or hydraulic control, which, depending on the training, carries out control tasks and/or or can take on control tasks and/or processing tasks. Even if the term “control” is used here, it can also expediently include or mean “rules” or “control with feedback” and/or “processing”.
  • the hydraulic actuator and thus the container can be moved very flexibly and quickly into any position using the directional control valve.
  • a leakage sensor for detecting a leak is assigned to the hydraulic actuator.
  • the hydraulic actuator can be monitored at any time for an internal leak using the leakage sensor, e.g. B. from the control device.
  • the leakage sensor can be integrated in the hydraulic actuator.
  • the closing member can be actuated hydraulically, with the hydraulic actuator and the closing member preferably being connected or connectable to the same hydraulic system.

  • the hydraulic system has an annular pressure line to which the hydraulic actuators of the lifting devices of the multiple treatment stations are connected, preferably distributed around a circumference of the annular pressure line.

  • the hydraulic system has an annular return line to which the hydraulic actuators of the lifting devices of the several treatment stations are connected, preferably distributed around a circumference of the annular return line. This can advantageously reduce the length of the line system of the hydraulic system and provide an intermediate storage facility.
  • the annular return line has a larger, preferably at least twice or at least three times larger, volume than the annular pressure line.
