Definitions

  • the machine is provided with a conduit connected to a supply of the oxygen-extracting protective gas and disposed so as to discharge into the forming mandrel of the machine in the zone of the lower end of the filling pipe, and there is a hollow chamber, open at its upper end, communicating with the end of said mandrel, and sewing as a gas storage means, provided in the mandrel above the gas discharge from said conduit.
  • the volume of hollow gas-storage chamber is at least as large as the volume of gas required for each draw down of the tube, less the quantity of gas which is supplied through the gas supply conduit during the draw down operatron.
  • the above said hollow chamber may be defined by the spacing between the filling pipe and the larger diameter mandrel which surrounds it. This provides a chamber of annular cross section, of selectable height, and open at the top.
  • a number of axial parallel and radially disposed plates can be provided within this hollow chamber to bring about a laminar type of gas flow.
  • the filling system can be freed of atmospheric air in simple fashion before the machine is started up, without the end of the packaging tube which has been closed in the last working stoke of the machine having to be opened, as is the case in known machines of this kind.
  • the continuous supply of gas in the vicinity of the outlet of the filling pipe effectively prohibits any entry of atmospheric oxygen into the filling system.
  • the gas column which forms above the gas inlet provides for a simple, virtually pressure-free gas supply to the bags which would otherwise only be obtainable with very expensive regulating devices, so that this gas supply neither inflates the bag nor imposes any additional strain on the closure seams of the bug by reason of gas pressure.
  • FIG. 1 shows an apparatus in accordance with the invention in conjunction with a plate dispensing machine
  • FIG. 2 is a cross section in the plane ll-Il of FIG. 1,
  • FIG. 3 shows a further embodiment of the apparatus, similar to that of FIG. 1, in conjunction with a weighing device, and
  • FIG. 4 is a cross section in the plane IV-IV of FIG. 3.
  • the apparatus illustrated in FIG. 1 comprises a discharge hopper 2 provided with a feed pipe 1 which may be incorporated therein one or more conducting cones, one being shown at 6.
  • a suitable flushing or protective gas which will take up oxygen, for example carbon dioxide or nitrogen, is introduced into the feed pipe, this gas then passing substantially vertically upwards in counter current through the pourable material which is flowing downwards in pipe 1. The material is thereby freed of the atmospheric oxygen trapped in it.
  • the gas is fed through a pipe 7 to an annular channel 8 which distributes it to the various nozzle openings 4.
  • a gastight housing 30 Adjoining the lower end of feed pipe 1 is a gastight housing 30 in which is arranged a plate dispensing device 31 of a known type. Gastightly connected to the housing 30 below the discharge point of this plate dispensing device 31 is a pipe 32 which projects into the forming tube or mandrel 22 of a known type of machine for making bags from a tube of packaging material.
  • This machine which is denoted 33, works with at least one continuous web of packaging material 34 which is first conducted over the shoulder 20 of the forming mechanism and is thereby applied around the forming tube or mandrel 22 and made into an endless tube 36 of packaging material through the agency of a heat sealing tool 35.
  • the so-formed tube of packaging material is drawn down intermittently from the forming tube 22 by means of a transverse sealing and severing assembly 37, charged during this operation through filling pipe 32, and finally transversely sealed above the top of the filling therein and cutoff so as to form a filled and closed bag package 38, the leading end of the remainder of the tube 36 of packaging material being transversely sealed at the same time.
  • the filling pipe 32 projecting into the former tube 22 preferably tenninates in the vicinity of the lower end of this tube 22, particularly when this pipe is of comparatively large cross section.
  • a further and larger diameter pipe 41 arranged around the filling pipe 32, is used to supply the gas for protecting the contents of the bags, which gas also serves for flushing, this pipe 41 being connected to a tubular conduit 25.
  • the hollow annular chamber 23 interposed between the pipe 41 and the forming tube 22 is divided up by a number of plates 39 extending axially and parallel relative to one another, and the lower part of pipe 41 terminates in the vicinity of the outlet from the filling pipe 32 in a number of downwardly directed nozzles 42.
  • the protective gas which is fed through the tubular conduit 25 emerges from the nozzles 42 and passes into the hollow space in the tube 36 of packaging material located above the transverse seal in the latter.
  • the further gas which has been fed in rises again into the hollow chamber 23 in the forming tube, thus creating a fresh gas supply.
  • the effect of plates 39 is that the flow of gas which is occasioned by this, and during the depression of the gas column, remains laminar, wherefore eddies, which could bring about admixing of the upper layer of gas with atmospheric air, are avoided.
  • two pipes disposed at the right-hand and the left-hand side of the filling pipe, can be used in the forming tube for gas storage,
  • a gas analyzer 43 the probe 51 of which will conveniently extend into the hollow space in the tube above the transverse sea].
  • This gas analyzer might also be used for automatic control of a regulator 44 which governs the supply of the protective gas through conduit 25.
  • a weighing device is used for dispensing.
  • One or more discharge weighers 46 of known type are disposed in housing 45 which is gastight or closed. The appropriate gas is fed in through the nozzles 4 of a nozzle stem 47. The discharge of the batches of pourable material measured out in the weighers again takes place through the filling pipe 32 mounted within the forming mandrel tube 22. 1
  • an additional gas storage device 48 which is arranged externally of the forming tube and comprises a plurality of channels 50 which are arranged parallel with one another.
  • a gas analyzer may also be provided in this instance, and it is also possible, in this and the other form of construction, to arrange a second gas analyzer 43 in the housing of the dispensing device to control the gas flushing operation during the feed of the pourable material to the dispensing device and, possibly, to automatically control a regulator 44 incorporated in the gas conduit 7.
  • the invention is not limited to the specific embodiments which have been described above. it is, for example capable of use in filling systems in which atmospheric oxygen admixed in the pourable material is removed by appropriate means other than flushing by means of gas or in which the pourable material is already oxygen free when it is introduced.
  • a bagmaking machine comprising a former, a hollow mandrel disposed within said former, means for drawing a web of packaging material over said former and between the latter and the mandrel to deform the web into tubular form means for longitudinally closing the tube of packaging material so formed, and a filling pipe projecting into.
  • said mandrel for depositing material to be packaged into said tube, the improvement comprising apparatus for reducing the atmospheric oxygen content of fluent pourable solid material deposited into said tube said apparatus comprising means for passing a protective gas, which is adapted to take up atmospheric oxygen in said pourable material, in counterflow through said material in loose condition, said means comprising a conduit connected to a supply of the protective gas and disposed so as to discharge into said mandrel in the zone of the lower end of the filling pipe, and further means defining a hollow chamber, open at its upper end, communicating with the end of said mandrel and serving as means for reversing and storing the flow of said gas, said further means being provided in the mandrel above the gas discharge from said conduit, said hollow chamber having a predetermined volume sufficient for accommodating the volume of gas necessary for each drawing operation of the tube of packaging material less the amount of gas discharged through said gas conduitduring each drawing operation.
  • the said gas supply conduit is a pipe surrounding the filling pipe and including a plurality of downwardly directed discharge nozzles at the lower end thereof.
  • a gas analyzer is mounted externally of the fonning mandrel and includes a probe extending below said forming mandrel, thereby to project into the hollow interior of a tube of packaging material passing downwards below the forming mandrel and communicating with said hollow chamber.
  • said apparatus is constituted by a self-enclosed unit including a device for dispensing the fluent solid material to the bagmaking machine, a device for feeding said material to the dispensing device, and an assembly for flushing the infed material with protective gas.
  • said unit includes a conduit through which protective gas is supplied to said device for feeding fluent, solid pourable material to the dispensing device, a gas regulator in the conduit, and a gas analyzer associated with said dispensing device and adapted to test the gas therein and control said gas regulator.
