  • the present invention further relates to a control system and a control method for controlling a pouch production of a packaging system.
  • Detergent pouches or pods, have become increasingly popular over the last number of years, both for the laundry washing and for dishwashing.
  • Detergent pouches are generally made from a water soluble material such as PVOH. This material forms the wall of the pouch and wraps the detergent, e.g. a powder, gel, and/or liquid.
  • Detergent pouches provide a number of advantages over other kinds of dosage methods, leading to increased convenience for the user.
  • the dose is always controlled and the same.
  • the ratio between the volumes is always controlled and the same. If handled properly, there is no or significantly less contact between the hands of the user and the detergent. This results in less skin irritation. There is also less spilling of detergent.
  • the production of detergent pouches is generally done with a packaging system, wherein a plurality of moulds are transported along a trajectory, and wherein different process steps are performed in order to produce a plurality of individualized pouches.
  • a problem during pouch production is the inefficiency due to downtime. Downtime for example occurs when the detergent is spilled. When the detergent is spilled on a part of a water-soluble foil outside a dedicated open compartment, the production needs to be halted until the spill has been cleaned.
  • the invention provides a packaging system for producing pouches having at least one compartment and made from a water-soluble first foil and a water-soluble second foil, the packaging system comprising:
  • the packaging system provides an improved control of the pouch production. This is achieved by the sensor system which acquires forming condition data of the at least one open compartment.
  • the sensor system which acquires forming condition data of the at least one open compartment.
  • the pouch production can be better controlled from an early stage as well.
  • the forming condition is not according to a desired forming condition, for example filling of the at least one open compartment can be prevented at a later stage.
  • the forming of the first foil into the open compartment itself can be influenced based on the acquired forming condition data by for example heating the first foil more and/or more locally.
  • the sensor system comprises an imaging device configured to image the forming condition of the open compartments, wherein the control system is configured for comparing the forming condition of the open compartments based on the imaging of the imaging device.
  • the forming condition can be better determined and compared to the desired forming condition.
  • the imaging device is a thermal imaging device configured to image a temperature distribution of the first foil downstream the first foil supplying device, wherein the control system is configured for comparing the forming condition of the open compartments based on the imaging of the temperature distribution of the first foil.
  • the temperature distribution image of the first foil allows for a more accurate and effective determination of the forming condition of the at least one open compartment.
  • a thermal imaging device is beneficial, because a temperature of parts of the first foil is influenced when said parts come into contact with a surface of the forming cavity.
  • the difference in temperature between parts of the first foil that have come in contact with the surface of the forming cavity and parts of the first foil that have not come in contact with the surface of the forming cavity can be effectively imaged by the thermal imaging device.
