  • the present invention relates to a method for changing hose reels, with the method steps: unwinding a first hose of a first hose reel by means of a manufacturing device, the first hose reel being accommodated in the manufacturing device and wherein an opening tool is arranged in an interior of the first hose; Providing a second hose roll having a second hose; connecting an end portion of the second hose to the first hose; and inserting the opening tool from the first tube into an interior of the second tube.
  • Manufacturing facilities for the production of automatically fillable valve bags made of PE film or PP fabric are equipped with hose rolls, the hose of which is unwound from the hose reel as endless material and processed into bags and separated by the relevant manufacturing facility.
  • blockages can arise inside the hose, ie an internal, local adhesion of layers of the flat hose lying on top of one another. These blockages can arise, for example, from manufacturing steps during the manufacture of the hose, such as: B. coating or perforating the hose. Blockages in the hose are loosened or broken using the above-mentioned opening tool of the manufacturing facility, the opening tool being arranged within the hose and can be mounted in a floating manner.
  • the opening tool When changing rolls, the opening tool must therefore be threaded or inserted from the first hose present in the production facility into the new, second hose.
  • a hose end of the first hose is manually inserted into a hose end of the second hose and glued there so that the hose ends overlap or are nested within one another.
  • the second hose can be pulled into the manufacturing facility using the first hose and the opening tool can be transferred from the first hose to the second hose. Due to this transfer of the opening tool and the necessary gluing of the hoses into one another, a roll change is carried out manually in such a production facility.
  • Such a roll change can take two to three minutes and, depending on the hose length and production speed, e.g. B. carried out three to four times per hour. The production facility stands still during the manual roll change.
  • the present invention is based on the technical problem of specifying a method that enables automated roll changing of hose rolls in a manufacturing facility with an opening tool.
  • the technical problem described above is solved by a method according to claim 1. Further refinements of the invention result from the dependent claims and the description below.
  • the invention relates to a method for changing hose reels, with the method steps: unwinding a first hose of a first hose reel by means of a manufacturing device, the first hose reel is accommodated in the manufacturing device and wherein an opening tool is arranged in an interior of the first hose; Providing a second hose roll having a second hose; connecting an end portion of the second hose to the first hose; and inserting the opening tool from the first tube into an interior of the second tube.
  • the method is characterized in that when connecting the end section of the second hose to the first hose, an exposed inside of the end section of the second hose is connected to an outside of the first hose in an overlapping manner.
  • the method is further characterized in that the first hose is separated along a separation point, the separation being carried out after the second hose has been connected to the first hose and before the opening tool is inserted into the second hose, the separation point being between a Connection point of the first hose with the second hose and an opening of the end section of the second hose is arranged and wherein after separation the opening of the end section of the second hose faces an opening of the end section of the first hose.
  • the second hose can be easily connected to the inside of the second hose in an overlapping manner by pressing on one side, without the need for threading the second hose into a hose opening of the second hose is.
  • the first hose and the second hose can thus be connected to one another in a greatly simplified and automatable manner, with the overlapping connection further enabling the opening tool to be transferred from the first hose into the second hose.
  • Changing the hose rolls can be carried out automatically during ongoing operation of the production facility without the production facility coming to a standstill.
  • these are the sides of the two flat layers of the hose in question inside the hose that face each other. An exposed inside is therefore not covered by the opposite layer of the hose in the exposed area.
  • the inside of the end section of the second hose to be connected to the first hose can be at least partially exposed before connecting to the first hose, with a part of the end section of the second hose being removed, and/or with a part of the end section of the second hose being separated and folded becomes.
  • one of the opposite layers of the flat hose is removed at least in sections in order to expose the inside of the hose covered by this layer.
  • Exposing the inside of the end section of the second hose can be a manual, preparatory process step before the second hose roll is handed over to the manufacturing facility. Exposing the inside of the end section of the second hose can be an automated, preparatory process step before the second hose roll is handed over to the manufacturing facility. Exposing the inside of the end section of the second hose can be an automated process step that can take place within the manufacturing facility.
  • a hose reel is provided as a second hose reel, which already has the required exposed inside of the end section.
  • the end section of the second tube can have a cutting edge and/or fold that is inclined to an unwinding direction, the inclination being less than 90°.
  • the cut edge and/or fold can limit the opening of the second hose.
  • the end portion of the second tube can form a pocket for receiving and threading the opening tool.
  • the end portion of the second hose may include a tab extending from the opening of the second hose to the junction of the first hose with the second hose, the tab having the exposed inside of the end portion of the second hose and with the outside of the first hose connected is.
  • the opening of the first hose can be at a distance from the opening of the second hose.
  • the second hose is therefore not inserted with its end section having an opening into an opening of the first hose or vice versa.
  • the opening tool is therefore at least temporarily not completely surrounded by hose material, but is temporarily and at least partially exposed in the area of the distance between the openings.
  • the opening tool is tilted by means of an adjusting device before insertion into the second hose and/or the opening tool is narrowed in an area facing the second hose.
  • an end of the opening tool facing the end section of the second hose is tilted towards the exposed inside of the second hose in order to enable the opening tool to rest securely on the exposed inside and to cause the opening of the second hose to expand.
  • the end section of the second hose or its opening is kept open by compressed air before and/or during the insertion of the opening tool, and/or the end section of the second hose or its opening before and / or during the insertion of the opening tool through a mechanical device, such as rollers, rollers or the like, is kept open.
  • the first hose pulls the second hose along after the connection, so that an unwinding of the first hose merges into an unwinding of the second hose without interruption.
  • a hose roll change can be carried out alternately from a first side and a second side of a hose level facing away from the first side, the hose level being spanned by the unwound hose.
