Definitions

  • the invention is in the field of packaging technology and relates to a device according to the preamble of the independent claim.
  • the device is used for strapping objects that are conveyed one after the other into a strapping position, strapped there and then conveyed away from the strapping position.
  • the objects are in particular cuboid, they are for example stacks of flat objects, in particular of printed products such as newspapers, magazines, etc.
  • a band, cord or wire-shaped strapping material is used, which advantageously has a sufficient inherent rigidity to be moved pushed to be able to.
  • a loop is created from a strapping band in a plane usually oriented perpendicular to the support surface, in that the strapping material is pushed and / or pulled, for example, into a loop channel predetermining the loop.
  • the article is positioned in the strapping position such that the loop passes underneath the article and around the article. Then the loop is moved out of the loop channel by retracting the strapping material (narrowing the loop) and applied to the article, then tightened and closed into strapping.
  • the means for feeding the strapping material into the loop channel is to retract the strapping material arranged for the reduction of the loop and for closing the strapping material in a central region under the support surface of the strapping position.
  • a loop guide means is used for erecting the loop instead of a loop moving means, which is designed such that the loop is guided by reduction from the loop guide means from the stationarily arranged in the waiting position Loop channel lifts and rises along the loop guide.
  • the base of the loop guide means is disposed in or immediately adjacent to the loop channel on its side directed against the loop interior, and the loop guide means is configured such that the further it has straightened up, that is to say it has moved away from the waiting position, the smaller will be the loop that is erected thereon ,
  • the loop channel substantially in the shape of a polygon with rounded corners and are provided as a loop guide means in the more distant from the center of Umreifungsposition polygon corners, provided against or over the Umreifungsposition arching guide rails.
  • the guide surfaces of the guide rails turned away from the loop interior are designed in such a way that they oppose as little friction resistance as possible on a movement of the strapping material sliding thereon.
  • the loop channel is thus, for example, substantially rectangular, wherein one of the sides of the rectangle in the support surface or under the support surface and, for example, extends centrally through the Umreifungsposition.
  • the means for feeding, retracting and closing the strapping material are arranged, for example, in the middle of the rectangle side running in the support surface and the guide rails in the two rectangle corners which are formed by the other three sides of the rectangle.
  • the loop channel may also have a more rounded shape and the loop guide means may curve integrally along the loop channel, or the channel may form a polygon with more than two corners provided with guide rails.
  • looping up through loop reduction over looping up by means of loop moving means is that a strapping apparatus can be made simpler, especially with less controlled moving parts.
  • a larger loop must be created in the waiting position, since it must already be shortened during erection and not only for the application to the object to be strapped from the erected position.
  • loop plane a plane formed by the loop
  • the steeper the loop guide means guides the loop out of the loop plane, the greater the angle between the loop plane and the guide means.
  • this angle is, the greater the normal force of the decreasing loop becomes on the loop guide and thereby the friction between loop and loop guide. If the slope of the loop guide exceeds a limit dependent on the coefficient of friction between loop and loop guide, the loop can not straighten up but sticks to the loop guide.
  • the loop will easily straighten up if the loop guide means rises flat out of the loop plane at least in its base region on the loop channel, and even better if the loop first shrinks in the loop plane and thus obtains an initial velocity across the length of the strap material before it is raised.
  • static friction By the measures mentioned static friction and thus a frictional engagement between loop guide and loop can be avoided.
  • the creation of a larger loop in the waiting position causes an extension of the required for the loop production loop channel, which may be additional means for introducing the strapping material in has the channel and possibly an enlargement of the whole device result.
  • both the lengthening of the cycle time and the enlargement of the device are disadvantageous and there is a desire to keep them to a minimum.
  • the object of the invention is now to provide a device for strapping with grinding in a waiting position and loop straightening by loop reduction, with which device it is possible to reduce the length of strapping material to be withdrawn for the straightening of the loop.
  • the device according to the invention is based on the finding that it is not necessary to ensure, over the entire length of the loop to be erected and also not over the entirety of those channel parts to which the loop guide means adjoins, that loop formation is possible by means of loop reduction without frictional engagement. It turns out that for trouble-free loop alignment it is sufficient to provide such conditions only at one initiation site, possibly at a small number of initiation sites, such that the strapping material begins to erect from the loop channel at the beginning of loop reduction at such an initiation site and thus exerts a pulling force on the remainder of the loop which facilitates loop erection such that this erection becomes possible with significantly steeper loop guidance from the loop plane than would be the case without initiation of loop erection.
  • the apparatus of the invention comprises an initiator which is equipped to locally impart to the strapping material an orientation perpendicular to the length of the strapping material and out of a plane (loop plane) formed locally by the loop.
  • the initiation site may relate to a channel location at which the loop-guiding means (e.g., a guide rail) is located, or may involve a channel location where it is not (e.g., between two guide rails).
  • the loop guiding means adjoins the initiating means, it is advantageous if the initiating pulse which the strapping material obtains by the action of the initiating agent has substantially the direction which the loop guiding means gives for a first phase of the loop straightening it carries out.
  • the length of strapping material that must be withdrawn, in particular for the first phase of the loop erection, is reduced, so that the loop to be created in the waiting position is shorter than without initiation means, that is to say flat with the flat plane leading out of the loop plane Loop guide means would be possible.
  • the time required for a strapping process is shortened and the device can optionally be made smaller.
  • the initiating means of the device according to the invention may be a passive means which draws energy from the loop reduction, or it may be an active means having a drive independent of the loop reduction, this drive being activated for example by a movement of the strapping material at the beginning of the loop reduction , Mixed forms of active and passive initiator are also conceivable.
  • FIG. 1 shows an exemplary device for strapping by means of loop formation in a waiting position and by means of loop straightening by loop reduction and loop guide by an advantageously passive or stationary loop guide means, as already briefly described above.
  • the device has a strapping position 1 (shown as hatched area of a support surface 2).
  • a means 3 is arranged, which serves for feeding, retracting and closing the strapping material 4, wherein the strapping material, for example, a polypropylene tape is unwound from a supply roll, not shown, and sealed, for example by welding.
  • the strapping material for example, a polypropylene tape is unwound from a supply roll, not shown, and sealed, for example by welding.
  • articles 5 to be strapped are fed successively in a feed direction F, strapped and, for example, guided away again in the feed direction F.
  • the device further comprises, for example, in the support surface 2 a loop channel 6, the loop of the means 3 for feeding, retracting and closing off and back to this means 3 back and is, for example, substantially rectangular.
  • the loop of the means 3 for feeding, retracting and closing off and back to this means 3 back and is, for example, substantially rectangular.
  • the two rectangular corners further away from the center 3 are arranged on the directed against the loop inside of the loop channel 6 per a guide rail 7, which bulge substantially transversely to the loop channel 6 and substantially from the support surface 2 against or on the Umreifungsposition 1.
  • a loop 10 is created by inserting and / or pulling the strapping material 4. After positioning an article to be strapped 5 in the strapping position, the loop 10 is reduced by retracting the strapping material 4, so that the loop, guided by the guide rails, lifts and straightens out of the loop channel 6.
  • the loop 10 is pulled in the figure 1 in the waiting position, that is in the loop channel 6, shown and dash-dotted in a partially raised position 10 ', in an erect position 10 "and in a placed around the object to be strapped position 10"'.
  • the upright position 10 " is defined by the end of the guide rails 7 and is arranged such that from this position the loop 10 is separated from the guide rails 7 by further reduction and substantially can be placed without guidance around the object 5 to be strapped.
  • the loop 10 is, for example, in a substantially vertical plane or a relative to the support surface or the waiting position relatively steep plane.
  • the device illustrated in FIG. 1 has an active or passive initiating means at at least one initiation site which locally impulses the loop created in loop channel 6 substantially in the direction of a first phase of loop erection as defined by the loop guiding means, so that the Loop 10 begins to line up at the beginning of loop reduction at this initiation point.
  • three exemplary initiation sites are designated 20.1, 20.2 and 20.3.
  • passive initiating means are to be arranged in a curved region of the loop channel 6, for example in a polygonal corner with guide rail (eg point 20.1) or channel curvatures between polygon corners and without guide rails, the latter channel curvatures against the polygon interior or from the Polygon can go out.
  • Active initiating agents can also be arranged at curved channel locations or also in the region of straight channel portions (initiation sites 20.2 or 20.3).
  • FIG. 1 shows an exemplary embodiment of a device which according to the invention can be equipped with an initiating agent.
  • Various features of the embodiment shown thus do not constitute a condition for the device according to the invention.
  • Such features are, in particular, the supply and removal direction F, which do not necessarily coincide and have to be aligned parallel to a part of the loop channel 6.
  • the position of the means 3 need not necessarily be arranged in the center of the strapping position 1 and not necessarily under the support surface 2.
  • the loop channel 6 (waiting position) does not necessarily have to be arranged completely in the support surface 2 and essentially form a flat rectangle. It may also lie in a plane inclined to the bearing surface 6 or form a curved surface and may be in the form of any polygon with straight or curved sides.
  • the loop guide means need not necessarily be configured as a plurality of guide rails 7 but may extend over a larger area over a greater length of the loop channel 6. It is also not a condition that the support surface 2 is horizontal, so that the term "loop erection" must be understood in a manner independent of gravity.

  • the rotation axis 31 of the rotating body 30 is arranged at a distance from the loop plane S, so that the application of the loop to the rotating body causes an angular momentum, by which the rotating body 30 is rotated in the clockwise direction and thereby the loop 10 from the loop channel 6 is lifted.
  • the rotary body 30 may additionally have teeth 32, by which a slippage of the loop is prevented in a direction opposite to the rotation.
