Definitions

  • the invention relates to a device for strapping of packaged goods according to the preamble of claim 1.
  • strapping guide frames usually four though rounded corner areas, but even with careful Manufacturing the leading strapping end can oppose a particular resistance.
  • 'Packaging presses' is the length of the strapping guide frame, in which the strapping is loaded must be 12 meters and more. This shows that the strapping in a strapping guide frame is quite problematic be and lead to considerable malfunctions can.
  • GB-A-2 082 138 shows and describes a semi-automatic Strapping device in which the leading End of the strapping inserted between two rollers whose prismatic circumferential profiles to the Grip the longitudinal edges of the strapping tool.
  • One of the Rolling is held in a fixed position and rotatably driven.
  • About friction of this driven roller on the strapping and this on the second role becomes the latter also driven by rotation. Only this second role is against the action of a spring within one of the strapping defined level on the strapping too tense or laterally outwards (e.g. regarding Fig. 9 to the outside) stored.
  • Fig. 9 of GB-A is intended to illustrate this. Now lie but the actual conditions are in no way like represents. Because only one roll can be moved to the side the other role remains fixed in space, stand on the two longitudinal edges of the strapping completely different forces if that Strapping tool across the plane defined by him in the direction of the arrow in Fig. 9 of GB-A-2 082 138 out of the area should be pulled out between the rollers. The means that one of the two longitudinal edges of the tape comes out sooner than the other long edge.
  • GB-A-2 082 138 creates an effect that the strapping agent away from the spatially fixed role hurls, which entails the risk that the The tape is not in the correct position on the packaged goods creates.
  • Another aspect of the invention relates a simplified way to ventilate at least one Role of the additional conveyor roller pair. Furthermore from the roles of the additional conveyor to the Strapping forces exerted as little as possible be, but in no case lead to malfunctions can.
  • the invention solves the problem in connection with the Features of the preamble of claim 1 by its distinctive features. After that it is provided that each roll at one end of a roll axis is arranged, which is remote from a roll pivoted recording is held, and that the Roles are synchronized with each other in such a way that Swinging out of a role inevitably leads to that the second roll is swung out accordingly.
  • Both are in accordance with the present invention Roll against the action of a spring force from the strapping relocatable away, in particular arranged pivotable.
  • the movements of the rollers take place synchronous and forced. So that can also the whip effect described above can be avoided, because this forced synchronization and control of both Roles and the additional conveyor different attacking forces on the two longitudinal straps avoids.
  • the device designated overall by 10 in FIG. 1 is used for strapping especially compressible Packaged goods 11 such as corrugated cardboard layers or the like.
  • the cross member 16 forms a press plate for compression of the packaged goods 11 or is a component thereof and stores a roughly indicated known strapping device 18, which is the formation of a closure overlapping strapping ends of the later around the packaged goods 11 tightened strapping serves.
  • the closure assembly 18 is a strapping agent store 19 assigned to how the closure unit 18 uniform in motion and thus synchronized with the Press plate 16 is driven and guided.
  • Both the posts 15, 15 'and the cross member 16 are strapping guides 20 to 23 in shape of straight channels or channel sections known Design assigned. It is also known, the portal-like Strapping guide channel structures 20 to 23 thereby to a self-contained strapping guide frame train that a bottom the goods to be packaged 11 or the pallet on which it is stored, traveling underneath Lance or a bayonet 24 is arranged, which also contains a straight strapping guide channel.
  • Strapping means 14 feed the strapping 14 in advance a strap guide 28, which next to the post-like strapping guide 21 and arranged in parallel (behind the drawing) is.
  • a strap deflection 29 vertically movable arranged, which has the task of strapping 14 each at the point at which the strapping means deflection 29 is located on a horizontally arranged To hand over strapping 30 which it continues to the closure unit 18. In the embodiment this happens through the strapping agent store 19 through.
  • the Strapping means 14 in turn becomes two Having conveyor rollers and the sealing unit 18 assigned conveyor 32 advanced, and 1 counterclockwise strapping guides 20, 21, 24, 22, and 23 as well as in between in the strapping existing strapping redirections 33 to 36 until the front end of the strapping 14 comes back into the closure assembly 18.
  • the additional conveyor has proven to be advantageous 37 at one point on the strapping guide frame 31 to be arranged on which the conveyor 32 transported straps 14 approximately 2/3 of its distance for a complete strapping guide frame filling has traveled. Consistently is therefore in the embodiment shown in Fig. 1 the additional conveyor 37 behind the third Strapping means deflection 35 in the area of the second vertical frame portion 22 is provided.
  • the arrangement is such that the roller 38 is driven by a motor 45 and that on the end of the axle 38 remote from the roller 38 a pinion 46 is rotatably attached, which with a Pinion 47 meshes, which at the associated end the axis 41 sits, the other end of the second role 39 wears.
  • the two rollers 38 and 39 are by means of a spring 54 clamped against each other.
  • the feather 54 is designed as a tension spring and from opposite Sides reachable adjusting spindles 55 in their Adjustable spring force.
  • adjustable stops 56 which are also are designed as screw spindles and at a central Store receptacle 57 with one in FIG. 2 and 4, not shown, but indicated in FIG. 1 with 58 machine-fixed console is connected.
  • the strapping 14 on its longitudinal edges frictionally driving peripheral surfaces of the rollers 38 and 39, as clearly illustrated in FIGS. 2 and 4, concave, in particular V-shaped swept. This ensures exact centering of the strapping 14 guaranteed in the nip and on the other hand also avoiding the rollers 38 and 39 favored (arrows 52 and 53) when the strapping 14 deducted in the direction of arrow 60 becomes. This situation is shown schematically in Fig. 4, and Fig. 5 shows the associated view.
  • Ventilation at least a roller 38 or 39 in the embodiment that synchronous ventilation of both roles 38 and 39 at the same time happens either directly by accessing the strap 14 on the peripheral surfaces of the rollers 38 and 39 (Fig. 2 to 5) or indirectly in that the Strapping means 14 opening directly on the flaps 61 attacks, which in turn the roles 38 and 39 in Transfer release position.
