Definitions

  • the invention is directed to an emptying device for bulk bags with an inner and outer bag, which are especially for dust-free emptying of with moisture sensitive, toxic or aggressive flowable bulk goods filled bulk bags.
  • the invention further relates to a method for Bulk bag emptying using the emptying device according to the invention.
  • Bulk bags to hold aggressive, toxic and / or otherwise more sensitive, such as hygroscopic, Bulk goods, usually consist of a dense Inner bag, also called inliner, and a mechanical one stable outer bag.
  • the inner bag usually consists of a sufficiently thick plastic film material or from a composite film, such as one with aluminum coated plastic film.
  • the outer bag consists of generally from a natural or synthetic textile material, often a ribbon fabric.
  • Bulk bags with an inner and outer bag usually show in a closable filling opening in the upper area, which also serves for venting when emptying Carrying straps to handle using hoists enable. They are on the bottom of the bulk bag brought together outlet necks, which by means of a lower and an upper bag binding, which in generally include both sacks are closed.
  • the outlet neck of the inner bag is also tight welded, usually below the lower one Bag binding.
  • the laced and / or welded The outlet neck of the inner bag can be used in a suitable manner folded and inside the outlet neck of the outer bag be arranged.
  • EP-A 0 637 552 teaches a dosing pallet for bulk bags, being under the opening of a receiving plate for the bulk Bag an open-topped container is arranged that Sidewall of the container a device for opening and Has closing the container and the bottom of the Container is connected to a metering device. After Place the bulk bag on the mounting plate, the If the neck extends into the container, the bindings can can be opened through the side door in the container.
  • the inner bag of the bulk bag made of a little flexible Material, such as an aluminum-laminated composite film, there are faults in the outlet Do not rule out bridging. This is particularly so then a major disadvantage if the Emptying device through the side door because of the toxic or aggressive nature of the product is possible.
  • GB-A 2 250 016 teaches a similar device: Except a receptacle for holding the discharge neck and the lower part of the bulk bag and a door in this bowl contains for the handling of the bag ties Emptying device also a squeezing device to the To reduce or completely interrupt bulk flow and to tie the sack again.
  • This device is also suitable not for easy emptying of bulk bags, especially those with a less flexible inner bag and / or a sealed inner bag because there are faults not when emptying by blocking the discharge always avoid contact of the filling material with the skin but not for work hygiene reasons is permitted.
  • the object of the invention is accordingly a Emptying device for bulk bags with an inside and To provide the outer bag, making it reliable and without Problems can be emptied without using the fill product to come into contact.
  • the emptying device also for emptying bulk Bags with little flexible inner sack, like the one at Find hazardous goods, be suitable.
  • Emptying device released Accordingly, one was found Emptying device for bulk bags with inside and Outer bag, comprising a holding device (3) for the bulk Bag and a substantially centrally located below Open container-shaped device, which thereby is characterized in that the container-shaped device as Double tube device is formed, comprising a inner tube (20), an outer tube arranged around it (7) with an outlet (8) and a lifting and lowering locking ring (9) for locking the upper end of that formed from the two tubes Annular gap.
  • the device according to the invention is suitable for dust-free and safe emptying of dangerous goods filled bulk bags.
  • the device is based on a Double tube device, its preferably funnel-shaped trained outlet via an attached flexible Connecting piece with the container to be filled can.
  • the emptying device comprises a Holding device for the bulk bag, which expediently as a mounting shell mounted on a frame with a sufficiently wide opening in the middle trained to carry out the bag outlet of the bulk bag is. Under the cradle is essentially central the double tube device arranged.
  • a preferred one Device additionally includes one at the Double tube device attacking lifting / lowering device, with which the distance between the receptacle and the Double tube device enlarged respectively can be reduced.
  • Locking ring of the double tube device With the raised and lowered Locking ring of the double tube device becomes the upper one Tight end of the annular gap formed from the two tubes locked. This is how to empty the bulk bag placed on the receptacle that the bag outlet through the opening is enough. After opening the lower sack tie becomes the sack outlet of the interlocked outlet necks of the inner and outer sack through the locking ring guided; the outlet neck of the inner sack will recede appropriate unfolding or rolling up in the Inserted inner tube, the outlet neck of the outer bag in the annular gap formed by the two tubes. Subsequently the locking ring is lowered to firmly secure the outer bag fix and fix the device to the environment to seal. After opening the top bag binding begins to empty the bulk bag. Furthermore, it is in generally useful, the double tube device lower to the interlocking outlet necks between the double tube device and the outlet tray to stretch.
  • a preferred embodiment of the emptying device how to empty bulk bags with a little flexible inner bag is particularly suitable because a Blockage of the discharge through additional stretching of the Spout neck of the inner bag is avoided characterized in that they have at least one within the inner tube up and down movable gripping device (21) for holding the bag outlet of the inner bag, which by means of an outside of Double tube device operable pulling device (11) from can be pulled down.
  • FIGS. 1 to 3 The invention and preferred embodiments thereof and their function are shown in FIGS. 1 to 3 explained in more detail.
  • FIG 1 shows a device for emptying a per se known packaging in the form of a sack Bulk container, hereinafter referred to as bulk bag, in schematic side view.
  • the bulk bag (1) has one the pourable inner bag with one around it outer bag (not shown in Figure 1, in Figure 2 No. 18 and 17).
  • Part of the outlet neck of the if necessary, additionally sealed inner bags is suitably folded inside or at the top of the outlet neck of the outer bag.
  • the bulk bag By means of Bulk bag fixed carrying straps (2), the bulk bag by means of a crane or industrial truck, which in turn already the function of a holding device for can take over the bulk bag, essentially centrally brought over the double tube device.
  • the Holding device for the bulk bag is a mounting device mounted on a support frame (4), in particular a receptacle (3) with a central arranged opening for the passage of the sack outlet neck (13).
  • the double tube device is located centrally under the opening of the cradle, in such a distance that the outlet neck of the bulk bag in the double tube device extends.
  • the emptying device contains a lifting / lowering device (5), with which it is attached by means of a bracket (6) Fixed double tube device raised and lowered can be.
  • Lifting / lowering device (5) can, as shown, on the Attack the support frame (4) or on a separate one on the Holder fixed bracket.
