Definitions

  • the invention relates to a device for welding waste according to the preamble of claim 1.
  • Devices for welding waste are mainly used in laboratories and medical facilities for safe and low-contamination disposal of toxic or infectious waste and hazardous waste, the waste to be disposed of by means of the device aerosol and liquid-tight sealed in foil bags.
  • a device for packaging waste by welding in foil bag which comprises a housing having a receiving space for a folded film tube and extending through the receiving space funnel.
  • a welding unit with two movable heatable welding jaws is arranged, between which an inwardly folded, guided from top to bottom through the hopper hose section of the film tube can be clamped and welded along a transversely extending over the hose section away weld.
  • a conveyor unit with two pairs of conveyor rollers is arranged below the welding unit, between which the tube section extends.
  • the conveyor rollers of each pair of rollers are pressed from opposite sides against an edge strip of the tube portion and driven to transport the tube portion in the opposite direction of rotation.
  • the emerging from the conveyor unit film tube consists of a series of contiguous bags, between each of which a weld is arranged.
  • the lower end of the hose portion located below the welding and separating unit with the last filled or welded bag is only safely separated if the weight of this lower end and the therein welded waste is greater than the resistance force along the Trennnaht contrary to flow heated tubular film a separation opposes. If the shrink-wrapped waste has only a very low weight, such as used syringes that are contaminated with toxic or infectious material, a safe separation is not always guaranteed. Moreover, since the tubular film is heated to flow along the dividing seams, it can not be ruled out that bags with welded waste at their ends along one or both dividing seams will leak leaking toxic or infectious material.
  • the DE 696 06 219 T2 discloses an apparatus for packaging products in mesh bags having a shaft through which an inwardly turned portion of a mesh tube extends, and two roller pairs of a conveyor disposed outside the shaft.
  • the pairs of rollers may be driven in a reversible direction to lift the outer portion of the mesh tube and thus bring it into the tube and lower its free end in the tube or to lift the mesh tube within the tube until its free lower closed end determines a particular one Height in the tube reached before a bag with open top created and the product is filled into the bag.
  • the present invention seeks to improve a device of the type mentioned in that the welded-waste can be welded either in individual separate bags or in several contiguous bags and that guaranteed even in the first case, a secure separation of the bag is when the weight of the welded waste is very low.
  • This object is achieved in that the transport direction of the conveyor unit for separating the lower end of the hose portion is reversible.
  • the conveying unit can be started or put into operation when separating a filled and sealed bag with the reverse transport direction by the feature according to the invention to the above the filled bag between the conveyor unit and the welding and separating unit located part of the hose section to exert an upward pulling force and thereby pull this part of the hose section upwards.
  • This ensures that this part of the hose section along a seam referred to below as a separating seam is reliably separated from the last filled and welded bag and thus from the lower end of the hose section below the welding and separating unit as soon as the upward pulling force is greater than the resistance, which opposes the heated separating seam located between the welding jaws of a separation.
  • the last filled and sealed bag then falls either immediately or at the latest when moving apart of the two welding jaws down in a arranged below the welding and separation unit collecting container.
  • the conveying unit is not started or put into operation in the reverse transporting direction, so that no upward pulling force is exerted on the welded seam being formed and the bags along the Weld seam can not be separated.
  • a preferred embodiment of the invention provides for a separation welding cycle for separating the lower end of the tube section from the welding section. and separation unit along the cutting seam in the tube portion supplied amount of heat is greater than the amount of heat that is supplied during a welding cycle of the welding and separation unit in the tube section to only weld this, but not separate. In this way, on the one hand, the separation of the lower end of the tube section can be facilitated without, on the other hand, jeopardizing a hermetic welding of the waste by excessive heating of the seam.
  • thermoplastic material of the tube is heated to a flow temperature along the dividing seam, while the smaller amount of heat supplied to the tube section during welding along a weld the thermoplastic material of the film tube is heated along the weld only to a lower temperature sufficient at the pressure exerted by the welding jaws to hermetically weld the tube section.
  • a waste batch to be welded can be placed both in one individually segregated bag or in one of several contiguous bags.
  • the reversal of the transport direction of the conveyor unit during the separating welding cycle is preferably triggered as a function of a state of the separating seam, expediently when the separating seam has been heated by the welding and separating unit until it has flowed.
  • the devices provided for this purpose advantageously comprise a time control which triggers the reversal of the transport direction of the delivery unit as a function of the time elapsed since the beginning of the heat supply to the separating seam.
  • a further advantageous embodiment of the invention provides that the conveyor unit comprises at least one pair of conveyor rollers, which are driven in opposite directions of rotation, and that for separating the lower end of the tube section, the direction of rotation of both conveyor rollers is reversible.
  • the conveyor unit has two pairs of narrow conveyor rollers, which are arranged on opposite sides of the shaft and extend only over part of the width of the hose section in the shaft, wherein the direction of rotation of the conveyor rollers of both roller pairs is reversible.
  • the conveyor unit comprises at least one pair of conveyor rollers, which are driven in opposite directions of rotation, and that for separating the lower end of the tube section, the direction of rotation of both conveyor rollers is reversible.
  • the conveyor unit has two pairs of narrow conveyor rollers, which are arranged on opposite sides of the shaft and extend only over part of the width of the hose section in the shaft, wherein the direction of rotation of the conveyor rollers of both roller pairs is reversible.
  • the welding and separating unit preferably comprises two heatable welding jaws which, for welding the hose section, approach the hose section by means of a welding jaw drive from opposite sides and can be pressed against the latter.
  • the two welding jaws each have a connectable to a power source heating wire, which is arranged between a Teflon tape on its side facing the hose section and a rubber band on its side facing away from the hose section is.
  • a still further advantageous embodiment of the invention provides that at least one of the two welding jaws is resiliently mounted counter to the direction of movement when approaching the hose section and provided with a contact for reversing the direction of the welding jaw drive when the spring outside of a central welding position of the welding jaw by a Resistance in the same movement path is compressed and triggers the contact.
  • the contact is preferably a reed contact, which is triggered by the approach of a permanent magnet during compression of the spring.
  • the control also serves to control the welding of the tube section in the welding cycle and the separation of the lower end of the tube section during the separation welding cycle, in which case the tube section is first welded along a weld, then the lower end of the tube section is separated along a separating seam arranged above the weld and finally the remaining tube section is welded along a weld arranged above the dividing seam.
  • a further preferred embodiment of the invention provides that in the welding cycle and in the separation welding cycle, first a transport of the film tube takes place, wherein the length of the transport path is freely selectable.
  • the apparatus 10 of the invention shown in the drawing is used to weld waste into a foil tube 12 made of a thermoplastic film which, during welding, is subdivided by transversal welds into a series of aerosol and liquid tight pouches, each containing a batch of wastes.

  • one of the user may select one of two desired modes of operation, namely, a welding cycle and a separation welding cycle.
  • the welding cycle is triggered by moving an object, for example the user's hand, over the sensor 88 into the IR radiation path. Thereafter, the indicator light 96 begins to flash in a different color, indicating that the device 10 is waiting and waiting for another input from the user.
  • transport of the hose portion 82 is initiated by driving the two pairs of conveyor rollers 58 of the conveyor unit 30. The transport takes place until the user again moves the hand away from the sensor 88 or until an adjustable maximum bag length is reached. The user can thus control by the residence time of the hand above the sensor 88, the length of the film bag to be formed to receive the waste.
  • the user may throw a batch of the waste into the throw-in port 32 from where they fall into the upwardly open hose section 82 or bag which has previously been welded in the welding and separation unit 28 at the lower end.

Thereafter, the two welding jaws 76 are again approximated to the hose portion 82 and pressed against this, but the heater wires more power than in the welding process is supplied. Due to the greater amount of heat generated thereby, the hose portion 82 between the welding jaws 76 is heated to flow.
