Definitions

  • the invention relates to a machine for strapping packages according to the preamble of claim 1.
  • the object of the invention is based on the object of designing a machine of the required type in a technically simple manner in such a way that the connection points of the strapping means are not at the corner of the package, strapping can be produced with great tension and the use of weldable plastic flat strip is possible without twisting.
  • the strapping means connection points are at a greater distance from the corner of the package and therefore not in the endangered area.
  • tight straps can be made.
  • the strapping agent tension results from the repeated pulling out of the strapping agent.
  • the first protuberance takes place when the strapping means enters the strapping position. Thereafter, the linearly moved slide moves in the downward direction, achieving a second protrusion of the strapping means.
  • the arm pivoting in the direction of the direction of movement of the package then only detects the strapping means section facing the back of the package and thereby generates the further inversion and thereby determines the strapping agent tension.
  • the gripper previously holding the end of the strapping means facing the closure device has moved into such a position during this process that it has then gripped the feed end of the strapping means.
  • the connection process can then take place. If the strap is plastic flat tape, the corresponding strap ends are welded.
  • the strapping means is then cut off in such a way that the end of the strapping means then present is held by the gripper. This then moves back to its starting position, the gap of which rotates through 360 °.
  • the machine for strapping packages P has a machine frame 1. Its table top 2 is surmounted by two columns 3 extending to the side of the machine frame, which are connected at their top by a yoke 4. From the latter, a boom 5 for holding the strap supply roller 6 starts.
  • the columns 3 support a shaft 7.
  • a sprocket, not shown, is seated on the shaft, around which a chain 8 is placed. This leads to a sprocket 9 of a drive motor 11 seated in the machine frame 1 on a rocker 10.
  • the guide means sit on the yoke 4 and are not shown in detail.
  • the slide 14 is a rod made of round material, which rotatably supports a deflection roller 15 at its lower end.
  • the slide 14 is non-rotatably guided, and the deflection roller 15 is at an acute angle to the package movement direction x.
  • the angle alpha between the package movement direction and the deflection roller 15 is 45 °.
  • the strapping means 16 drawn off from the strapping means supply roller 6 loops around one or more strapping means guide rollers 5 'and is then guided to the deflecting roller 15 of the slide 14. From there, the strapping means runs as a freely stretched chord S to a gripper 17 arranged below the table top 2.
  • the gripper 17 is part of a schematically illustrated locking device 18, which is controlled by a drive 19.
  • the latter is coupled via a cam-controlled link 20 and a further transmission link 21 to an arm 22 mounted in the machine frame 1. Its pivot pin has the reference number 23. Am free end, this arm 22 carries a roller 24 which extends in the tying plane yy.
  • the finger-like gripper, designated 17, is rotatably seated in a slide 25 that can be moved up and down.
  • the slide 25 can be displaced in the horizontal plane parallel to the strapping plane y-y.
  • Two guide rods 26 are used for this purpose.
  • the slide 25 Between the gripper 17 and the upper guide rod 26, the slide 25 latters a pin 27 which carries a gearwheel 28 on one side of the slide 25 and an idler gear 29 on the other side thereof, which has a pinion 30 of the gripper 17 combs. Both gears 28 and 29 are firmly connected to the pin 27.
  • the gearwheel 28 extends above a stationary toothed rack 31 which runs in the horizontal direction. According to FIG. 3, the gear wheel 28 is in engagement with the toothed rack 31.
  • a jack 32 of the same modulated is designed with one arm and is supported around a transverse pin 33 of the slide 25.
  • the free end of the pawl 32 forms a tooth 34.
  • the latter cannot enter the toothing of the gearwheel 28 when the slide 25 is lowered, since an inclined flank 35 of the pawl 32 is supported on an edge 36 of the rack 31.
  • the pawl 32 is constantly acted upon by a compression spring 37 accommodated in the slide 25. If the carriage 25 moves in the direction of arrow z in the upward direction, the pawl 32 can engage with its tooth 34 in a tooth gap of the gear wheel 28 and accordingly blocks the rotary movement of the gripper 17.
  • the gripper 17 is provided with a central bore 38.
  • a clamping plunger 39 runs in the latter. At its free end, the latter forms a clamping jaw 39 ', which interacts with a counter jaw 17' of the gripper 17.
  • the clamping jaw 39 'and counter jaw 17' determine the position of the gripper gap S, which extends in the region of the strapping plane y-y.
  • the end of the clamping plunger 39 opposite the clamping jaw 39 ′ forms a head 39 ′′, on which a coupling member 40 that can be displaced on the pin 27 engages.
  • the drive 19 serves to control the same.
  • the coupling member 40 can be used to control the coupling member 40 in the dot-dash days 3, so that then in this position the jaw 39 'has stepped out of the area of the gripper gap S with the release of the strapping means held there.
  • an upper pressure jaw 41 is pivotally mounted on the other side of the tying plane y-y. This is associated with a heating plate 42 and a lower pressure jaw 43.
  • the upper pressure jaw 41, the heating plate 42 and the lower pressure jaw 43 can be pivoted into the region of the strapping plane y-y.
  • the lower jaw 43 can make an upward shift.
  • the pressure jaw 43 is also assigned a holding clamp 44 for the strapping means.
  • the machine is in its initial position.
  • the end of the strapping means 16 ' is held by the gripper 17 and runs from there to the deflection roller 15, around which the feeding end of the strapping means 16 is placed.
  • This position corresponds to the dash-dotted position of the tendon S in FIG. 1.
  • the pressure jaw 41, heating plate 42, lower pressure jaw 43 and holding clamp 44 are in the displaced position. This means that they do not extend in the tying plane y-y.
  • Fig. 8 illustrates that the gripper 17, which was previously still meshed, has moved in the upward direction, while the upper pressure jaw 41 and the holding clamp 44 are piloted and the strapping means end 16 1 facing the closure device grasp and clamp it.
  • the gripper 17 in turn has opened; this means that the clamping plunger 39 has moved into the dot-dash position according to FIG. 3.
  • the slider 14 has moved linearly downward, with the strapping means 16 being inserted, along the rear side P 'of the package, beyond the closure device 18.
  • the deflection roller 15 lying at an acute angle to the package movement direction x, only the strapping middle section A facing the package rear side P 'extends in the strapping plane yy, see FIG. 4.
  • the next step in the movement is that the carriage 25 travels downward with the gripper 17. The extent of the downward movement is so great that the tooth engagement between the rack 31 and the gear 28 is not yet established. The position according to FIG. 9 is then present, the end of the strapping means having left the gripper 17.
  • the arm 22 has pivoted about its pin 23 to form a further indented section of the strapping means.
  • the roller 24 has only captured the strapping section A.
  • the gripper 17 then moves to the other side of the pressure jaw 41 and closes, as a result of which the strapping means is held at two points in the region of the connection point.
  • the next work step shown in FIG. 11 now follows. This consists in that the gripper 17 travels in the upward direction. Then the lower pressure jaw 41 and the heating plate 42 advance. The corresponding strap sections are heated. The heating element 42 then moves back and the lower pressure jaw 43 in the upward direction. This will make the corresponding Strapping middle sections welded. After a corresponding cooling time, the gripper 17 moves downward. Here, the tooth engagement between the toothed wheel 28 and the toothed rack 31 is established. At the same time, the strapping means is pulled over the knife edge 45, which is adjacent to the lower pressure jaw 43, severing the strapping means. The then present end of the strapping means is held exclusively by the gripper 17, see FIG. 12.
  • the lower pressure jaw 43 now opens and the upper and lower pressure jaws move back out of the strapping plane, so that the package P can be removed.
  • Fig. 12 it can also be seen that the gripper gap S lies in the horizontal. Now the gripper moves in the direction of the arrow to the other side of the upper pressure jaw 41.
  • the gear wheel 28 rolls on the rack 31, and the gripper 17 is rotated through 360 ° via the intermediate wheel 29, while the slide 14 with its deflection roller 15 in the upward direction moves.
  • the starting position according to FIG. 6 is then present without the strapping means being wound onto the gripper 17.
  • the gap S has thus rotated 360 ° in time with the back and forth movement of the slide 22.
