Definitions

  • the invention relates to a device for the continuous production of tubular Bags for bulk goods, using a tubular shoulder over which from a Flat web film pulled a tube and through a suitable device with a Longitudinal seam is closed, as well as arranged on both sides of the hose and with Driven tool pairs for processing, such as closing and cutting the tubular bag.
  • a film take-off station which the flat web film over a tubular shoulder, pulls off a roll using vacuum or other elements.
  • the pull-off station usually consists of driven belts that slide the film against the fill tube press and move to the packing unit.
  • One in the area of the drive belt arranged welding and / or sealing tool closes the longitudinal seam of the film tube.
  • the drive speed of these continuously running belts is determined by determines the processing speed of the subsequent packaging device in which the bags through tools working transversely to the film tube with heat and pressure, be closed and cut.
  • the packaging speed plays an important role in this type of equipment is influenced by various factors.
  • the tools for closing the bags must be able to act with sufficient pressure for a sufficient time.
  • the length of the filling pipe influences the fall time of the bulk material and hence the packing speed. After all, in many cases the speed is to be taken into account with the tools used to seal the bags be reset every time the packaging is carried out.
  • the invention has for its object in devices of the type described in continuous throughput, increasing the packing speed, the filling tube and thus reduce the drop height and the duration of action of the tools to close the bags to extend.
  • the object is achieved in that two alternately pairs of tools accessing the film with a closing movement, the film thereby pull off continuously so that one pair of tools grips the film with the closure and pulls off at the desired throughput speed over the tube shape shoulder, while the second pair of tools opened at a distance the length of the bag on the next processing point of the tubular film reset, closed and with the Hose is moved in the pulling direction before the pulling tool pair opens.
  • the sealing tools By pulling off the film with the sealing tools, the separate belt pull is saved, which leads to a shortening of the filling tube for the bulk goods to be packed leads. This not only reduces the fall time, but also protects the Bulk goods connected. Because the sealing tools stay closed for so long this pulls off the sealed bag and thus the film, the exposure time is extended, which allows a reduction in pressure and especially temperature. This is a very desirable effect because lower temperatures reduce energy consumption. A lower pressure also allows the design and drives to be lower Assign performance level.
  • a continuous throughput is a prerequisite for high throughput with short cycle times Peel and edit the film. So that the film is pulled off continuously resetting the locking tools (sealing tools) is faster than that Peel off the film. This is achieved by separate drives for each of the tool pairs, operated independently of each other by programmable controls become.
  • Fig. 1 shows a schematic representation of two moved by controlled drives Tool pairs "a” and “b” that glue or weld from the film tube 1 the film under the influence of heat and pressure in a continuous pass Create bag 2 filled with bulk material.
  • the stroke of these tool pairs corresponds to "a", "b” the length of the manufactured bags 2.
  • a closure device 5 for the longitudinal seam preferably an ultrasound Welding device, formed into a film tube 1.
  • the film tube 1 is replaced by one the tool pairs "a", "b” are initially closed at the bottom and thus formed into a bag 2, the filling tube 6 with bulk material inserted in the area of the shaped shoulder 3 is populated.
  • the control of the drives for the tool pairs "a” and “b” are structured in this way. that with the closing of one of the tool pairs, the filled film tube 1 not only compressed and closed, but also over the full length of the bag 2 is pulled down. This also removes the film from the roll 4 via the shape shoulder 3 continuously pulled without using a driven film take-off and into one Foil tube shaped.
  • both tool pairs "a” and “b” are closed. While the pair of tools “a” closes the filled film tube 1 into a bag 2 and this pulls the tool pair “b” open for the reset movement.
  • a not Drawn drive moves the opened tool pair “b” according to FIG. 2b below Bypassing the closed pair of tools “a” by the length of a bag above.
  • the opened tool pair “a” is driven by its drive Bypassing the pulling tool pair "b” to the level of the next bag closure reset.
  • Each of the tool pairs "a” and “b” leads when the film is pulled off vertically and when Closing and opening of the tool pairs prevents horizontal movements. So that these Movements do not interfere with each other and the continuous movement when pulling off the film is ensured, the drives for the tool pairs can be controlled separately and the tools are mounted on supports that are on one side on opposite sides of the Foil tube are freely protruding and are moved guided.
  • the embodiment shows two stationary, columnar supports as a carrier 31 for the Housing 32 which receives the drives for the movement of the tool carrier 33.
  • a drive is provided in the housing 32, the this moved relative to the supports 31 vertically.
  • another drive is used which the tool carrier 33 relative to the housing 32 in the sense of an opening or closing movement of the tools not shown controls.
  • the housing 32 and the tool carrier 33 can be exemplary Linear motors or spindle drives of a known type can be used.
  • Fig. 3a shows how the housing 32 after opening the tool holder 33 with the tools not drawn according to the selected bag length to the next one Seal point is reset upwards.
  • the tool carrier 33 and so the tool pair is closed.
  • the housing 32 is carried along with the clamped by the tool pairs - not drawn - tubular film, according to the adjustable length of the tubular bag - Moved down into the position shown in Fig. 3c.
  • the tool carrier 33 are opened and at the same time the housing 32 upwards into the 3a shown position.
  • a second pair of tools is required for continuous operation to the arrangement shown in Fig. 3 is to be arranged.
  • the tool carriers are mounted on one side, so that the tool carrier intended for receiving the tool pairs Collision-free in the free space between the housings thanks to controlled drives can be moved.
  • FIG. 4 schematically shows the construction form shown in FIG. 3 with the supports 31 and 41, and the tool carriers arranged in mirror images on the housings 32 and 42 33 and 43 in supervision.
  • the tool carriers are on one side on the housings 32 and 42 stored so that the movements of the tool carrier 33, 43 and thus also the tools through controlled drives to the desired horizontal and vertical movements can be adjusted with adjustable length and speed.
