Definitions

  • the present invention relates to an apparatus to separate flexible packaging material from its contents and a process to separate packaged content from its packaging material.
  • Consumer goods such as for example dry food products are typically packaged in flexible packaging material such as a sachet.
  • the packaging material may be paper based or comprise polymer material.
  • Packaged consumer products, such as dry food products are often produced in an amount that exceeds the envisioned demand or are filled in a packaging with too much or too little product ending up in the sachet. Indeed, issues like supply chain irregularities, seasonal consumer preferences, variation in filling procedures are factors that may result in stocks of the packaged consumer product that will not be used anymore and are left to be discarded or in products that are filled with an amount of product that was not intended. Discarding these nonused products clearly could result in complications in recyclability, for example where the content of the packaging allows for organic recycling but the packaging itself requires a different recycling regime. In case the consumer product is not expired and is still of excellent quality to be consumed or used otherwise, destruction of the excess of packaged product results in unnecessary waste of material, such as unnecessary waste of food, that could result in significant avoidable costs.
  • a complication is that once the consumer product, such as a dry food product, has been packaged, it is very time consuming to open the individual packages again to separate the packaging material from the consumer product. This task becomes even more complicated when the amount of excess product is high, such as faced on an industrial scale in a factory for producing packaged food products.
  • the need for automating the separation of packaging material, at least to some extent, from the packaged product is eminent. Complications in this process are, however, diverse. For example, the individual units of packaged material can differ in size and type of material.
  • the packaging material is typically not food-grade, and in case the consumer product to be separated from its packaging is a food product, no traces of packaging material should be mixed with the food product.
  • the packaged consumer product may be inhomogeneous.
  • the food product may comprise a base mixture, typically in powder form, and particulate ingredients of a bigger size, such as for example dried noodles, dried pieces of vegetables, mushroom etc.
  • the process should allow for opening of the packaging, emptying the packagings, separating the consumer product from the remaining of the packaging without leaving much content in the packaging and creating a packaging material stream to be discarded or recycled and one or more dry consumer product streams, to be discarded, recycled or optimally, to be reused in a food-safe manner.
  • US 4543029 relates to a device for cutting flexible containers containing fungible material. It discloses a device for cutting of bags of paper, synthetic material, jutes, or the like, containing powdery up to granular and/or granulated or flocculent materials, as well as for loosening or separation of the goods from the bags or its parts.
  • GB1235721 relates to improvements in and relating to handling bags containing powdered and other particulate material and discloses an apparatus for emptying bags of powdered or particulate materials comprising a slitter unit in which the filled bags are fed between spaced rotary cutters for slitting the bag walls into a multiplicity of strips to release the contents and from which strips and content are delivered to a separator unit.
  • US5193753 relates to an apparatus for disintegrating flexible packaging materials and discloses an apparatus for reprocessing, i.e. disintegrating, used packing materials, for example unsorted domestic waste paper.
  • US2005/0019141A1 relates to a separation device and discloses a device for separating a sheet-shaped packaging from the material packaged therein, particularly bulk goods, comprising a drum, and a driver adapted for driving the drum about a center line thereof, wherein the drum forms an accommodation space for the packaged material and is provided at the inside with blades for ripping apart the packaging.
  • US9174755 relates to a sack cutting means for offshore emptying of content from a packaging comprising means for cutting up the package, means for separating the package from its content and means for removing the emptied package from the cutting means.
