Definitions

  • the invention relates to a filling device and a method for filling of bulk goods in bags open on one side, drums with inner bags, or so-called big bags.
  • a well-known alternative is the endless hose system Advantages compared to filling systems used so far, that here also low dust the container can be changed.
  • the disadvantage of this system lies in the low absorption capacity of the so-called endless bag of approx. 30 m at ⁇ 100 ⁇ m (micrometers), whereby the low material thickness, if a container is filled with> 25 kg net, cause a problem can.
  • the sack can easily be lifted out of the drum tear.
  • the endless bag can be closed by means of clips or welding take place, here also only thin bag material ⁇ 100 microns Advantage is. Low temperatures can be used for welding or when clinging, the end becomes denser because the thinner material thicker material should be used to compress it better slightly leaky floor closures can be expected.
  • a bottling plant essentially consists of a feed hopper, one Dosing device and the so-called filling head.
  • a dosing device Swivel slide, squeeze hoses or screw conveyors, as a filling head become simple open pipes or tapered, conical, open Cylinder (truncated cone) used. Sealing from the filling head to one side open sack (big bag) is usually made with inflatable cuffs without Ring (advantage: very tight on the outside, material is stretched.
  • shut-off device e.g. a flap at the end of the filling head install?
  • a normal shut-off device valve, flap or slide at the open end of the filling head prevents falling of Product from the filling pipe, since this shut-off device also comes with the product If the container is contaminated, the product also falls from it when the container is changed downward.
  • the object of the present invention is a method and an associated To provide a device to ensure that when changing containers no product is released into the environment.
  • the invention accordingly relates to a device for low-dust Change of containers of one-sided open sacks and big bags with dusty ones or granular bulk material, which is characterized in that in the filling head Means are provided to one after filling a container Filling head to grasp remaining container hose ("residual container") and to be withdrawn through the outlet opening of the filling head.
  • the inventive The device has the advantage that when changing the container Danger of environmental pollution in comparison with known devices is less.
  • an empty container can already be under be arranged on both sides of the remaining container before this through the outlet opening of the filling head is pulled upwards.
  • the Gripping means can for example be a movable gripping tool, e.g.
  • a movable gripping pliers or gripping arm with which the remaining container packed and up through the exit opening, i.e. opposite the direction of the filling stream can be removed. It is conceivable that the filling head via a line with shut-off device in connection with a Vacuum source is. This has the advantage that a suction effect in the Filling head is adjustable when the remaining bag is removed.
  • the gripping means are advantageously one that ends in the filling head or in the filling tube or additional pipe connected to the filling head, below also called “residual bag suction pipe", which with a vacuum source in Connection is established.
  • the additional suction tube makes it possible for a after closing and separating the filled container at the filling head remaining container hose, hereinafter also referred to as “residual container”, sucked in and out through the suction pipe connected to the filling head can be.
  • the remaining container can be sucked off particularly easily, if this closes to form a residual bag when the container is removed becomes. It is conceivable that the suction pipe is connected directly to the filling pipe is and that the residual bag is withdrawn through the filling tube becomes.
  • the filling head jammed sack (inliner, big bag) by means of a closing device with clips, cable ties, bag closers or the like twice, i.e. by means of two clamping points provided at a distance from one another, locked.
  • the filling container can then between the closures be separated (cut through).
  • the remaining bag remains on the filling head back. Thanks to the remaining bag, the filling head remains even after removal of the filled container closed to the outside. Even if the clasp of the remaining bag should not be carried out exactly, can be put on no product can get into the environment due to negative pressure on the filling head, because the direction of flow to the exhaust fan (vacuum generator) of a dedusting system acts.
  • two pinch points can also be a single pinch point wide set come.
  • the residual bag suction pipe by means of a shut-off device is lockable. This has the advantage that no bulk goods are filled in the suction pipe can get.
  • the suction pipe can also be used permanently be subjected to a negative pressure. This expediently extends Residual bag suction tube into the filling head. This allows the remaining bag easily grasped and vacuumed. If the residual bag suction tube is movable and movable a certain distance in the direction of the outlet opening the remaining bag can be particularly easily gripped.

  • the suction tube is preferably movable in the Filling head continued as a shut-off device with a hollow shaft, which is the outlet opening of the filling head closes to the outside when changing the container.
  • the present invention also relates to a method for filling of dusty or granular bulk material, which characterizes it is that the remaining container on the filling head through the outlet opening is subtracted.
  • This method has the advantage that the Can change faster and the risk of contamination the environment is less.
  • the container is by means of a wide weld seam or two spaced apart and the clamping points running transversely to the bag opening are closed such that after the filled container has been cut off, the filling head closing residual bag remains.
  • the remaining bag can then through the Outlet opening by means of a vacuum and / or movable gripping means subtracted from.
  • the container is expediently equipped with at least 2 bag closers, Cable ties or clips to form two clamping points.
  • two disconnection points single wide pinch point, e.g. by welding, manufacturing and cut them in about the middle so that a closed, filled container on the filling head and a container that closes the outlet opening The remaining bag remains.
  • the filling head with a connected, closed container is advantageous a preferably light one even before the filled container is separated Vacuum applied. This has the advantage that no dust particles from the Filling head can escape to the environment, as this due to the negative pressure be sucked towards the vacuum source.
  • the residual bag is preferably drawn off into a dedusting system. There or in front of the dedusting system, a device for separation can be used of the residual bag may be provided.
