Definitions

  • the invention relates to a device for filling and closing a packaging material according to the preamble of claim 1.
  • a bulk material fed under gravity through a filling device is filled into a knitted fabric designed as a mesh tube, which is cut to a length suitable for processing, placed around an outer surface of a filling tube and after filling is closed in the area of a filling opening.
  • a device which processes the respective network hose in sections, has a disadvantageously low filling capacity with a high level of design complexity.
  • the invention has for its object to provide a device of the type specified, the components while reducing the technical Expenses are developed in such a way that the bulk goods can be packed quickly and that the sealing means provided as a second seam bag or sack can be reliably sealed with little energy expenditure.
  • the rolled-up endless knitwear is provided as a semifinished product which has pre-cut openings in the unwinding direction at a distance corresponding to the size of the two-seam bags or sacks, which can be separated with the first and the second separating element with low energy consumption, so that the technical requirements can be reduced to the device as a whole and a function of the components which is not susceptible to faults even under rough operating conditions can be achieved.
  • a welding bar combined with the second separating element can be provided in an advantageous embodiment, which connects the two layers of material of the endless knitted fabric directly or via an intermediate connecting or adhesive layer, with the use of the same materials for the knitwear and the connecting material the disposal effort of the packaging used can be reduced.
  • Fig. 1 the overall designated 1 device for filling and closing a packaging is shown in a schematic diagram, which has a frame 2 with which a the feed frame 5, which is located on a supply roll 4 and is in the form of endless knitwear 3, is connected.
  • the endless knitted fabric 3 can consist of cotton, jute, plastic fibers or the like.
  • the continuous knitted fabric 3 running from the supply roll 4 in the direction of the arrow 7 is deflected in an inlet area 6 of the device 1 in an expedient embodiment 50 such that it can be inserted into the area of a central longitudinal plane 10 of the device 1 after a plurality of feed parts 8 provided as deflection rolls .
  • the endless knitted fabric 3 can be pre-separated into the region of respective double-layered connecting webs by means of a separating member, not shown, for example as a thermal separating bar, so that the endless knitted fabric 3 is formed in addition to a corresponding opening made on the longitudinal side walls of the two-seam bags or sacks Section division with a predetermined sack or bag size is only connected in the upper part so that effective tensile forces are reliably absorbed when moving in the feed direction 7 and further transport of the sacks or bags is possible even when filled.
  • a separating member not shown, for example as a thermal separating bar
  • the in the upper edge area connected via the connecting webs and in the form of the pre-separated two-seam bags or sacks hanging freely downward knitted fabric 3 is then guided in the feed direction 7 to a guide plate 9 which diverges the two connecting webs (FIG. 2), so that the bags or sacks in Area below a Filling funnel 11 present an upper filling opening 12 and through which the respective bag or sack can be filled with the bulk goods pre-portioned using a balance (not shown).
  • the two connecting webs in the form of sack flaps of the bags or sacks are closed by pressing members 13, 14 of a feed part 15 acting on both sides, and the connecting webs of the endless knitted fabric 3 run into the area of a closing part 17, in the area of which, in a practical embodiment, the Connecting webs positively connecting closure member 18 and a second separating member 19 can be effective at the same time and so both a quick closure and a separation of the filled bags or sacks can be achieved with little effort.
  • the closure member 18 is provided with a welding bar 22 (FIG. 3) which can be heated via an inner heating part 21 and which is provided with at least one pressure member 24 which can be moved perpendicularly to the feed direction 7 of the endless knitted fabric 3 towards a counter plate 23 (arrow direction 20).
  • the welding bar 22 can be moved, for example, with a hydraulic or pneumatic drive (not shown) in the direction of the arrow 20, so that, with sufficient pressing force, the endless knitted fabric 3 can be closed in the area of its connecting webs, for example, when the welding bar 22 has a temperature of approx . 130 ° C and the endless knitted fabric 3 consists of a thermoplastic material.
  • the welding bar 22 and the second separating member 19 are one at the same time on the connecting webs of the endless knitted fabric 3 acting composite part is provided so that at a feed rate corresponding to the spacing of the openings, the bags or sacks can be closed at the same time in the area of their filling opening by means of a horizontal weld seam and separated by means of a vertical separation process in the area of the double-layered connecting webs. It is also conceivable to provide both the welding bar 22 and the counter plate 23 with a heating part, so that different material thicknesses can also be closed with a high degree of security.
  • FIG. 3 illustrates the welding bar 22 and the second separating member 19, which are arranged in the region of a holding plate 27 (FIG. 1) forming an adjustable closing region in the feed direction 7, so that different divisions of the endless knitted fabric 3 in the form of the Sacks or bags can be adjusted in the direction of the arrow 26 by means of respective quick releases 28, 28 '.
  • the length of the welding bar 22 is such that the connection area of the largest dimensions of the sacks or bags is reliably grasped and a complete welding is thus formed even in the case of smaller embodiments.
  • the counter plate 23 is in turn connected to a holding plate 29 which can be adjusted in the feed direction 7.
  • the top view according to FIG. 1 shows that the second separating member 19 is advantageously designed as a pressure stamp 30, the cutting part 31 of which protrudes toward the feed plane 10 (FIG. 3) can be inserted into a mold recess 32 in the counter plate 23 and separates the knitwear (not shown).
  • the plunger 30 can be provided on the edge side in each case with clamping parts 33, 33 'projecting from the counterplate 23 and designed as spring-loaded bolts, with which the endless knitted fabric 3 to be separated in the upper edge region can be tensioned in a first movement phase when the closing part 17 moves in the direction of the arrow 20, afterwards Using the cutting part 31, the thermal separation process, for example, can be carried out in a second movement phase and a complete separation of the bags or sacks can thus advantageously be achieved.
  • the device 1 is provided for the movement of the endless knitted fabric 3 in the feed direction 7 or 7 'with two pairs of drive belts 36,37, each having paired pressure rollers 35, as suitable feed parts 15,15'.
  • the two pairs of drive belts 36, 37 are each arranged in the connecting webs of the sacks or bags at different gripping heights, the front pair of drive belts 37 being lowered in the feed direction 7 'so far that the closing area of the endless knitted fabric 3 above them is good for the components of the closing part 17 is accessible (Fig. 3).
  • a band feed 38 and on the other hand a rear band feed 39 can be connected in front of the area of the welding bar 22, so that a transport into the area of the closing part 17 is possible from these and corresponding via the welding bar 22
  • Labeling and connecting materials can be brought into a positive connection with the upper areas of the bags or sacks.
  • this increases the seal strength and, on the other hand, information about the contents of the packaging can be attached with little effort.
  • the sealing of the filler opening 12 can be achieved by welding the rear band and the manufacturer's sleeve to the intermediate sealing areas.
  • a corresponding discharge conveyor belt 40 is assigned to the frame frame 2, in which the individual sacks or bags (not shown) leave the device 1 in the area of an end opening 41 and for another Packaging can be provided.
