Definitions

  • the present invention relates to a flexible container manufacturing arrangement.
  • the present invention relates to a flexible container manufacturing arrangement for manufacturing flexible containers such as flat pouches, stand-up pouches, super pouches, quad bags and pillow bags.
  • a container is any receptacle or enclosure for holding a product used in storage, packaging, and shipping. Things kept inside of a container are protected by being inside of its structure. The term is most frequently applied to devices made from materials that are durable and are usually at least partly rigid.
  • a container can also be considered as a basic tool, consisting of any device creating a partially or fully enclosed space that can be used to contain, store, and transport objects or materials.
  • a well-designed container will also exhibit ease of use, that is, it is easy for the worker to open or close, to insert or extract the contents, and to handle the container in shipment.
  • a good container will have convenient and legible labelling locations, a shape that is conducive to efficient stacking and storing, and easy recycling at the end of its useful life.
  • Flexible containers include flat pouches, stand-up pouches, super pouches, quad bags and pillow bags.
  • flexible containers of the stand-up pouch variety are becoming increasingly widely used as replacement or refill packs for household goods, such as liquid soap and powdered coffee. This already assists in the reducing of household waste because the stand-up pouches are made of lightweight material whereas the original containers in which the initial goods are bought are normally made from high quality thick and sturdy plastics. However, even such quality containers wear overt time and eventually need replacing.
  • a flexible container manufacturing arrangement which is adapted to manufacture flexible containers with inner liners.
  • a flexible container manufacturing arrangement which is adapted to manufacture a vast range of flexible containers including
  • the stand-up pouches may have bottom gussets.
  • the super pouches may have top and/or bottom gussets.
  • the quad bags may have side gussets.
  • the flexible container manufacturing arrangement may be adapted to manufacture the flexible containers with inner liners.
  • the flexible container manufacturing arrangement includes the following elements in combination:
  • the profile/shaped sealing unit with “single hit” sealing bar may also allow for much quicker tooling changes.
  • the 4 reel unwind may be adapted to allow the arrangement to run not only pillow bags (which machines currently utilize this unwind configuration), but also pouches both with or without an inner liner.
  • the use of compensators for each layer of material may allow for the tensions between each of these layers to be monitored and adjusted in the most accurate fashion possible.
  • registration marks on both the top and bottom webs is unique to the flexible container manufacturing arrangement as other pouch machines use one reel of material which is slit and folded to keep the top-bottom registration within tolerance.
  • the flexible container manufacturing arrangement may make use of individual reels, compensators and registration marks to achieve the desired tolerance.
  • the shaped/profile seal unit may be designed to only contact the material once per print.
  • the use of the single profile may also allow for easier/quicker tooling changes.
  • the gland insertion unit on the flexible container manufacturing arrangement may pre-heat the gland flange on its sealing surface, as well as heating the material feeding into the unit.
  • the flexible container manufacturing arrangement may be designed in such a manner as to be “modular”.

  • the flexible container manufacturing arrangement is adapted to manufacture flexible containers with inner liners.
  • the flexible container manufacturing arrangement is adapted to manufacture a vast range of flexible containers including
  • the object of the flexible container manufacturing arrangement according to the invention is to provide for a machine with unique versatility.
  • This versatility allows it to run a vast range of packaging products, such as:
  • the flexible container manufacturing arrangement according to the invention eliminates the need to have multiple machines to run this range of products.
  • the flexible container manufacturing arrangement also presents the user with the option to run these products with an inner liner.
  • a - The 4 reel unwind is not utilized on any other known pouch manufacturing machine. This allows the flexible container manufacturing arrangement to run not only pillow bags (which machines currently utilize this unwind configuration), but also pouches both with or without an inner liner.
  • B - The use of compensators for each layer of material allows for the tensions between each of these layers to be monitored and adjusted in the most accurate fashion possible. This ensures that all the layers of material (regardless of construction) would pull evenly and with uniformity.
  • the shaped/profile seal unit of the flexible container manufacturing arrangement is designed to only contact the material once per print.
  • Other pouch machines make use of multiple profiles on this seal as to “double-hit” the seal area, requiring lower sealing dwell times and thus increase cycle times on the machine.
  • the use of the single profile also allows for easier/quicker tooling changes.
  • the gland insertion unit on this flexible container manufacturing arrangement will preheat the gland flange on its sealing surface, as well as heating the material feeding into the unit. This will guarantee a strong seal and allow for lower sealing temperatures, preventing any blistering and blemishing of the seal. This facilitates the production of pouches with abnormally thick materials.
  • the flexible container manufacturing arrangement is designed in such a manner as to be “modular”. This means that units/modules can be added at a later stage, should the customer require these additions. For example, the red line below in Figure 7 below where a zipper unit could be added in to an existing machine, requiring no further effort than extending the sections of the machine’s frame.

Abstract

L'invention concerne un agencement de fabrication de récipient souple, qui est conçu pour fabriquer un récipient souple avec des revêtements internes. L'agencement de fabrication de récipient souple est conçu pour fabriquer une vaste gamme de récipients souples comprenant des sachets plats, des sachets qui tiennent droits, des super sachets, des sacs quadruples et des sachets à coussin. L'agencement est conçu pour fabriquer les récipients souples avec des revêtements internes et comprend les éléments suivants en combinaison : une configuration de déroulement de 4 (ou plus) bobines ; des compensateurs individuels ; un système d'enregistrement double/« de marque d'œil » ; une unité d'étanchéité de profilé/forme ayant une barre d'étanchéité « à coup unique » ; et un mécanisme de presse-étoupe/bande préchauffé. Les éléments sont des composants modulaires.
