Definitions

  • the invention relates to a device and a method for the mechanical evacuation and sealing of plastic bags, in particular filled with fresh meat and fresh fish, made of airtight and moisture-proof weldable plastic.
  • the construction effort required for this should be kept low, and handling should also be simple for the operating personnel.
  • the device by means of which this can be achieved is characterized by a vertically adjustable clamping device which receives the filled bag in the area of the bag opening and is formed from at least two clamping jaws, a suction sword which can be inserted between them in the bag and which together with the clamping device in a support frame is arranged, and a welding device formed from welding jaws which are adjustable relative to one another and by means of which the bag opening can be closed and welded after the bag has been evacuated and / or gassed.
  • clamping device for example by means of an adjustable threaded spindle or the like, jointly adjustable in height relative to the roller conveyor.
  • At least one clamping jaw of the clamping device should be horizontally displaceable or pivotably attached to a guide piece by means of a servo device in the form of a pressure cylinder, a toggle lever or the like for receiving the bag. Furthermore, in order to adapt to different bag openings, at least one clamping jaw should be horizontally displaceable or, with its end receiving the bag, pivotable in the direction of the suction sword on a guide piece, the clamping jaws, in order to create a good fit of the bag, in their cross-sectional shape as in each case outward wedge pieces should be formed.
  • the suction sword can be formed in a simple manner from two plates arranged at a distance from one another by means of spacer strips, suction openings in these and / or the spacer strips preferably in the edge region of the suction sword can be incorporated.
  • its insertable end should be double wedge-shaped or bevelled in the two corner areas.
  • the suction sword can be divided approximately in the middle and clamping jaws can be arranged between the two sword parts, which interact with adjustable clamping jaws provided on both sides of the suction sword.
  • the method for mechanically evacuating and closing plastic bags made of airtight and moisture-proof weldable plastic, in particular filled with fresh meat or fresh fish is characterized in that the filled plastic bags are clamped in the area of the bag opening in a clamping device which consists of at least two clamping jaws and is arranged in a supporting frame, that a suction sword reaching through the jaws is then partially or fully inserted into the bag until it rests on the goods to be packed, that the bag is subsequently evacuated and / or gassed, and that the clamping device and the suction sword are then lifted vertically and returned to the starting position and the bag is simultaneously closed and welded in the area of the bag opening by means of adjustable welding jaws.
  • a clamping device which consists of at least two clamping jaws and is arranged in a supporting frame
  • clamping device and the suction blade together horizontally displaceably in the support frame and then to close and weld the opening of the bag in the end position.
  • the device designed according to the invention is not only easy to manufacture in terms of its construction and thus in an economical manner without great construction expenditure, but above all it is by means of this device possible to reliably evacuate and seal plastic bags in a short time with simple handling.
  • the high work output is particularly advantageous since a bag can already be clamped in the clamping device while the previous bag is still being sealed.
  • an adaptation to the respective sizes of the bags and their materials can be carried out without difficulty, and the timing of the individual process steps can easily be controlled according to the respective circumstances, so that the device designed according to the proposal can be used in a variety of ways.
  • the air is sucked off directly above the goods to be packed by means of the suction sword that can be inserted into the bag, the evacuation can be accomplished reliably with little energy expenditure in a short time without parts of the bag being able to lay against one another.
  • the device for mechanical evacuation and closing of bags 2 made of airtight and moisture-proof weldable plastic consists of a clamping device 21, a suction sword 22 and a welding device 23, which are assigned to one another in a two-part supporting frame 11 are installed.
  • the lower part 12 of the support frame 11 is in this case provided with a roller conveyor 19 on which the bags 2 to be closed or the containers 3 which can possibly accommodate them and which are equipped with built-in carriers 20 are provided.
  • the upper part 13 of the supporting frame 11, which carries the clamping device 21, the suction sword 22 and the welding device 23, is height-adjustable relative to the lower part 12.
  • a threaded spindle 15 fastened to the upper part 13 is used, which is mounted in a guide sleeve 14 attached to the lower part 12 and the height of which can be adjusted by means of a gearwheel 16 which can be rotated via a spindle 17 and a crank 18.
  • the clamping device 11 is formed from clamping jaws 31 and 32 mounted in guide pieces 33 and 34, onto which the bag opening 4 is clamped by hand.
  • the clamping jaw 31 is here horizontally displaceable by means of a pressure cylinder 35, so that the bags 2 can be clamped without difficulty.
  • the clamping jaw 32 can be locked in different positions by means of an elongated hole 36 provided in this or the guide piece 34.
  • a further pressure cylinder 38 which is fastened to a plate 37 and whose piston 39 is fixedly connected to the clamping device 21, serves to adjust the height of the clamping device 21.
  • the suction sword 22 which can be passed between the clamping jaws 31 and 32, consists of two plates 41 and 42, between which spacer bars 43 are arranged and into which suction bores 44 are incorporated in the outer region.
  • the suction sword 22, the end of which can be inserted into the bag 2 is chamfered in both corner areas, is connected to a vacuum pump via a suction line 45 which is only partially shown.
  • a cylinder 46 fastened to the plate 37, the piston 47 of which is connected to the suction sword 22, also serves to adjust the height of the suction sword 22.
  • a further pressure cylinder 49 is provided, which acts on the plate 37, which is held by means of rods 48 arranged parallel to the roller conveyor 19.
  • the welding device 23 is formed from two welding jaws 51 and 52 which are adjustable relative to one another.
  • a pressure cylinder 53 acts on the welding jaws 52.
  • the bag 2 drawn with dash-dot lines, is clamped with its opening 4 onto the clamping jaws 31 and 32.
  • the clamping jaw 31 is briefly displaced inwards with the aid of the pressure cylinder 35, so that the bag 2 can easily be put on.
  • the suction sword 22 is activated by means of the pressure cylinder 46 retracted into the bag 2 by the path marked with.
  • the clamping device 21 and the suction sword 22 are then horizontally displaced by the distance b into the other end position marked B (FIG. 3).
  • the bag 2 is evacuated, and it can also be gassed during this process.
  • the suction sword 22 'shown in FIG. 4 is divided approximately in the middle and between the two sword parts clamping jaws 32' and 32 "are arranged, which together with clamping jaws 31 'and 31" attached to both sides of the suction sword 22' Act.
  • This is achieved by a pressure cylinder 35 'equipped with two pistons which can be displaced outwards and by means of which the clamping jaws 31' and 31 "are connected. In this way it is possible to simultaneously clamp two bags 2 'and 2" and to evacuate them using the suction sword 22' .
