Definitions

  • the invention relates to a device for producing container products from plastic materials, in particular by carrying out a forming, filling and closing process, with the features of the preamble of patent claim 1.
  • EP 2 595 789 B1 discloses a method for forming a plurality of containers from a preform, the method including the following steps:
  • Figure 2 shows a perspective oblique view of only a portion of the device according to Figure 1, showing the mold-closing unit and the guide and holding device as well as the separating device with their respective functional elements;
  • Figure 3 again shows in perspective oblique view only a partial area of the representation according to Figure 2;
  • Figure 5 partly in elevation, partly in longitudinal section, the guide and holding device with support strips and underlying cutting blades of the separating device;
  • a device frame is designated with 10, which has a rectangular box shape with a front side 12 running in a vertical plane.
  • an extruder device designated as a whole with 14 is arranged, which is designed according to the relevant prior art and has a feed hopper 16 for plastic granulate and a motor-driven extruder screw unit 18 in order to feed plasticized plastic mass to a hose or extrusion head 20.
  • a plurality of container products 26 corresponding to the number of molding surfaces 28 lying next to one another in a row can thus be formed in one molding step from a single extruded molding tube, which is designated by 24 in Figure 6.
  • FIGs 1 and 2 which show the molding device 22 in the open state, the molding surfaces 28 of the left-hand part of the molding device 22 are visible.
  • the molding surfaces 28 in question have been omitted for the sake of simplicity of illustration.
  • a blowing/filling device 30 is provided for the optional blow molding and a metered supply of dispensing or filling quantities during a filling process of the container products 26 molded in the molding device 22.
  • the blowing/filling device 30 has a number of blowing/filling mandrels corresponding to the number of container products 26 to be molded, which are not shown for the sake of simplicity of illustration, but in terms of their structure and function essentially correspond to the structure described in WO 2014/060101 A1.
  • this expansion process can also be carried out by blowing in blowing air, preferably via the blowing/filling mandrels, which then also serve as blowing mandrels (positive pressure gradient).
  • the closing unit 32 of the molding device 22 has a slide as a carrier for each mold half of the overall mold, of which the slide on the left in Figure 2 is designated 46 and the right-hand slide is designated 48.
  • the two slides 46, 48 are guided horizontally on guide rails 50 of the carrier plate 36.
  • a left-hand main jaw 54 is attached to a holding body 52 attached to the slide 46 and a right-hand main jaw 58 is attached to a holding body 56 attached to the opposite right-hand slide 48.
  • the main jaws 54, 58 form the main part 60 of the container products 26 in the closed position (not shown), which receives the respective container contents (see Figure 4).
  • a holding body 62 forming a type of slide plate, to which a left-hand head jaw 64 is attached, is mounted horizontally displaceably on the upper side of the holding body 52 of the left-hand main jaw 54.
  • a further holding body 66 is arranged horizontally displaceably on the upper side of the holding body 56 of the right-hand main jaw 58, which forms the support for a right-hand head jaw 68.
  • the opposing head jaws 64, 68 can be moved into the closed position independently of the main mold jaws 54, 58 in order to form the head region 70 (see Figure 4) of the container products 26 and to close the filled containers in this respect.
  • a separate actuator is provided for each of the main jaws 54, 58 and for the head jaws 64, 68, of which the actuator provided for the main jaws 54, 58 is coupled to the support plates 46 and 48 in order to move them along rails 50 on the support plate 36.
  • the actuator assigned to the head jaws 64, 68 is coupled to the holding bodies 62, 66 of the head jaws 64 and 68, respectively. Both actuators each have a lever gear 72, which are arranged one above the other, so that essential parts of the lever gear 72 located below are not visible in Figure 2.
  • each of the lever gears 72 has a spindle drive 74 or 76 as a drive, each with an associated electric drive motor 78.
  • the spindle drives 74, 76 are connected via struts 80 to a cross member on the back of the carrier plate 36, so that the unit formed from the lever gears 72 and the spindle drives 74, 76 can move together with the carrier plate 36 on the vertical guide 40 in accordance with the activity of the ball screw (not shown).
  • the guide rods 82 coupled to the drive 74 hold the two opposing head jaws 64, 68 in their open position.
  • Corresponding guide rod drives underneath serve to control the main jaw pairs 54, 58.
  • the closing unit 32 can be moved vertically downwards from its starting position during the shaping, filling and closing process together with the movement of the molded hose 24 and, after the shaping, filling and closing process has ended, can be moved back up to the starting position. Further details can be found in WO 2014/060101 A1.
  • the guide and holding device 34, its carrier plate 38, as well as the carrier plate 36 of the closing unit 32 can be moved on the vertical guide 40 of the frame 10 and, in a similar manner to the carrier plate 36, has horizontal guide rails 84 on which a left-hand actuating unit 86 and a right-hand actuating unit 88 are guided so as to be horizontally displaceable.
  • the actuating units 86, 88 form the actuator for associated guide and holding parts, with the actuating unit 86 actuating a first left-hand guide and holding part and a second left-hand guide and holding part, while the second actuating unit 88 actuating a first right-hand guide and holding part and a second right-hand guide and holding part.
  • the left-hand first guide and holding part and the right-hand first guide and holding part are each formed by pivotable support strips 90 and 92, which are of the same design and extend in a direction parallel to a mold parting plane 94 (see Figure 6) when in a pivot position corresponding to their operating position.
  • each support strip 90, 92 is attached to an associated pivot shaft 96 or 98, which extend out of the housing of the respective associated actuating unit 86 or 88 parallel to one another next to the mold parting plane 94 in the vertical direction.
  • a swivel drive for each of the swivel shafts 86, 88, which can be operated by a corresponding machine control.
  • the two support strips 90, 92 can be pivoted forwards from their holding position shown in Figure 2 by means of the respectively assignable pivot shaft 96, 98 and can then be moved upwards again over the forming device 22, wherein after pivoting back into the holding position the forming hose 24 can be gripped in order to take it, again with the forming device 22 open as shown in Figure 2, into a lower holding position in which the separating process according to the invention takes place, which will be described in more detail below.
  • the guide and holding device 34 as a whole can be moved between an upper and a lower functional position by means of a further, second displacement unit 99 ( Figure 1). Further details in this regard and in particular the interaction with the first displacement unit 85 are the subject of WO 2014/060101 A1, the disclosure content of which is also the subject of the present patent.
