Definitions

  • the invention relates to a device for wrapping preferably palletized piece goods with a tubular or hood-shaped stretch film according to the preamble of claim 1, as well as a corresponding method according to the preamble of claim 14.
  • Devices for wrapping general cargo are, as far as their basic components are concerned, usually designed like the device described by European patent application 0 344 815 A1. They regularly consist of a machine frame, on which a lifting frame (in approximately vertical direction) can be moved up and down.
  • the lifting frame usually carries the reef brackets, which in turn can be moved relative to the lifting frame in the transverse direction (ie in approximately horizontal direction) in order to stretch the stretch film after the stretch film has impacted the reef brackets in the transverse direction, ie to stretch elastically, ie the so-called horizontal stretch to be able to produce.
  • a horizontal or transverse stretch of 10% to well over 50%, based on the unstretched dimensions of the stretch film in the transverse direction, is usual.
  • the reef bars can be designed very differently.
  • the possibilities here range from a very simple, finger-like design up to the rewinding tabs, which are often T-shaped in shape, comprising a substantially vertical shaft for receiving the reefed stretch films and a substantially horizontally extending one having a certain radius of curvature executed section which forms the relevant corner of the foil held on the reef straps held round.
  • the reef bows are regularly inserted into the inner, lower end of the tubular or hood-shaped stretch film.
  • each Reffbügel is assigned a Refforgan in the form of a motor-driven Refrefolle.
  • the Refforgan can be moved up to the relevant reefing bar so that its reefing roll presses on the stretch film using the reefing bar as an abutment and thus pulls the stretch film onto the reefing bar, thus taking advantage of the frictional forces that occur.
  • the stretched stretch film then settles in said accordion-like folds on the reefing bars.
  • the finished stretched stretch film section is then transversely traversed by a corresponding process of reefing, i.d.R. stretched in a largely horizontal direction.
  • any wrinkles and in particular the said accordion-like folds are strongly pressed against one another.
  • two or more layers of stretch film strongly pressed against each other at various points - as seen in the horizontal direction - lie on each other, so it forms wrinkles, which can be described as "Überlappfalten".
  • the coefficient of friction "film against film” is generally smaller than the coefficient of friction "film against reefing bow”.
  • reef bars (during the stretch film coating process) in motion and sliding along the reefing bars tend to pull apart along the reefing bars as they slide so that the overlap is removed before the overlap patches reach the top edge of the reefing bar reached.
  • individual overlapping creases do not pull apart fast enough, but jump off unsurfaced from the reef bar.
  • the reefing bow seen in the vertical direction, run sufficiently long and the impact on the reef bar betechnikstelligenden Refforgane with their driven Reffrolen each about in the middle of the reefing bar, or far enough away from the trigger-side upper edge of the reefing, to let attack, so that below the reefing rolls stretch film is stretched accordion-shaped and above the reforwarding, due to their tensile forces, the stretch film hood over a not too small distance smoothly rests on the extended area of the reefing.
  • larger dimensions of the reef bar is undesirable. It leads to additional construction costs, in particular to a greater overall height of the plants and especially increases the way that must be covered in the vertical direction of the reefing brackets or holding them lifting frame in each packaging process. This affects the working speed of the device, which is of particular importance.
  • the invention is therefore based on the object to provide a device and a method of the generic type, which is or quickly and by simple means capable of a side surfaces enveloping stretch film section so aufrefeffen on the reefing, so that the risk After stretching, when the film is pulled off, overlapping creases reach critical areas of the reef bows, is substantially reduced and the film is not pulled or damaged thinly in these areas.
  • each Refforgan has Reff beautifyingen with which it can act at least temporarily simultaneously in two spaced apart in the refraction zones on the stretch film that the between the two zones located stretch film section is arranged without overlapping on the respective reefing brackets.
  • each Refforgan at least a first refreshment and a reference to the Aufreffraum subsequently arranged second train role, wherein the Refrefolle when Aufreff desert the device at its passing with the stretch film in contact circumference has a lower peripheral speed than the tension roller, so that between the refresher and the pull roll located stretch film section is drawn, preferably stretched and is arranged without overlap on the respective reefbügeln. Any wrinkles that may be in the area between the zones will be pulled smoothly in both the impact and peeling.
  • the two said zones are spaced so far apart that the Kochlappfalten reliably dissolve. Ie. that only in a few cases overlap gaps between the zones are present and can reach the critical area. This effect is advantageously achieved both when the film meets the reefing bars and when the film is removed therefrom.
  • each Reforgan has two drivable, with respect to the Aufreffraum successively arranged Reff beauen that are formed by roles, namely a first refreshment and a second, arranged behind traction roller whose distance from each other is advantageously adjustable.
  • the device is designed so that the refroll, so that role to which the film meets at the beginning of Aufreffvorgangs first turn at its passing with the stretch film in contact circumference at a slower peripheral speed than the second, that subsequent traction roller, so that between The stretch film section located on the rollers is pulled or smoothed or pulled without creases during the impact.
  • Such pulling causes any wrinkles which have occurred in the region between the two rollers when the hood is hit to be reliably pulled apart.
  • the device is designed so that the stretch film during operation of the device at at least one point on an imaginary, direct connecting line between the said zones neither comes with the reefing bars nor with the Refforganen in touch.
  • it is particularly effective to smooth wrinkles that have fallen into the area between the two rollers when they are picked up and pulled off. Because wrinkles that may have entered this area can easily be pulled apart in such a design, since the friction of the individual film layers in the region of the folds is lifted as soon as the relevant fold on the direct line connecting the said zones neither with the reefing bars nor with the Refforganen in Touch comes. Any force acting perpendicular to the fold and which could frictionally hold the fold together is canceled.
  • a design of the device of the type is particularly preferable in which one of the two rollers presses the stretch film against an elastically resilient region of the respective reefer bracket during operation of the device.
  • a particularly effective interaction of the two roles is ensured in their effect and avoided in any case an overload of the film in the area between the two roles.
  • slip if necessary can occur between the film and the roller.
  • the spring force of the elastically resilient region is adjustable, so that it can be precisely tuned when slip occurs.
  • At least one of the two rollers preferably the tension roller, so that they do not pass continuously with the stretch film when rolling on the stretch film in contact. This favors the pulling apart of wrinkles that have come into contact with the area between the rollers.
  • the device can be simplified if you only positive when pulling the train, d. H. motor, drives and the Refrefolle drives negative when operating the device, d. H. slows. Even then arises between these two roles a tensile stress, which reliably pulls out when encountered in the area between the two roles wrinkles.
  • rollers each have their own, independently operable motor drive and / or independently operable Zustellorgane.
  • the advantage is nevertheless to be given in the following of the figures for the specific embodiment, structurally very simple and very reliable solution that is suitable under certain conditions even for retrofitting existing systems, as on the piston rod of the delivery device instead of the previous single refresh with their engine only the roller tandem must be placed, which is also driven by only a single reef motor thanks to the chain or belt drive and therefore does not require any fundamental changes in the control of the machine.
  • the procedural part of the object is achieved by the method according to claim 14, wherein on the stretch film during the impact by the Refforgane each by means of two spaced-apart Reff beauen at least temporarily simultaneously in two spaced apart in Aufreffraum zones on the stretch film is acted upon that of Termination of the impact between the two zones located stretch film section is arranged without overlapping on the respective reef bracket.
  • any wrinkles that may be in the area between the zones are also pulled smoothly so that they can not get into the critical area of the upper edge of the reefing bar.
  • the device according to the invention which is not shown here in its entirety, consists essentially of the known basic components mentioned at the beginning in connection with the discussion of the prior art, which can be designed or modified in many ways. Numerous other well-known components that go to the complete Carrying out a packaging process of the type in question are required - depending on the individual case - added.
  • Fig. 1 shows one of usually four - but occasionally more, about six or eight - Reffbügeln 1, as well as this associated Refforgan 2.
  • the reef bracket 1 is intended to be mounted on a drive, the him along an arrow S in the horizontal direction - and can move.
  • the Refforgan 2 consists of a feed device 4, here in the preferred form of an advantageously pneumatically operated feed cylinder, consisting of a Refrefolle 5a and a tension roller 5b Reffrios, a two rollers driving Reffmotors 3 and a care for the required translation chain or Belt drive 6.
  • the feed device 4 is controlled accordingly and ensures that the refroll 5a and the pull roller 5b can be moved to their working position and withdrawn at any time from its working position, respectively by a movement to the left or right along an arrow V.
  • Die Feed device 4 is usually mounted with its base 7 on the same drive unit, which also moves the reef bracket 1 along the arrow S back and forth. In this way, it is ensured by simple means that the Refforgan 2 is moved back together with the Reffbügel 1 when moving apart of the reefing brackets for the purpose of cross-stretching the stretch film.
  • the reef bar 1 has a critical region K at its upper edge on the discharge side.
  • this critical region K only a few, preferably almost no, overlap creases should pass from a stretch film reserve 8 held up by a stretched film supply. This is because in the critical region K, the bow section changes greatly.
  • the reefing bow tapers locally in the area of the constriction 9, whereas it subsequently expands the film even more in the area of the upper bow part 10. If the film slides along this area K, its load changes in quick succession. Because of this, overlapping creases should as far as possible not reach this area, otherwise they increase the risk of film thinning or cracking under the influence of this fast load change.
  • the critical range K is in the usual, used in practice systems in the area of the upper edge of the reef bar. Alternatively, however, is the use from top to bottom almost smooth reefing without significant cross-sectional changes conceivable, with such reefing bars designed it is then only to prevent that Matterlappfalten "jump off" of the reefing.
  • the Refforgane be delivered, so that the stretch film between the free-running roller 11 and the refroll 5a is frictionally held.
  • the reef motor 3 is started, whereupon the stretch film is pulled by the frictional contact with the refining roller 5a on the reef bar 1, down.
  • the lower end of the stretch film tube is also frictionally engaged by the downstream tension roller 5b.
  • the refining roller 5a acts via a first contact zone (zone Z1) and the tension roller 5b via a second contact zone (zone Z2).
  • the chain or belt transmission 6 interconnecting the two rollers is designed in this embodiment such that the downstream tension roller 5b rotates faster than the refining roller 5a, the film which is located between the two rollers 5a and 5b is in the area between the two Contact zones (Z1 and Z2) pulled tight and even temporarily extended by a certain amount depending on the difference in the rotational speeds of the two rollers 5a and 5b.
  • the lower traction roller 5b is not supported in its operating position advantageously directly on a substantially rigid portion of the reefing bow 10, but rather cooperates with a bracket 12, seen in the horizontal direction by a screw 14 fastened and spring loaded in the horizontal direction by means of a screw 13 held compression spring in that a pressure of the Ironing 12 is realized to the tension roller.
  • the bracket 12 may also be mounted resiliently pivotable. In this case, the bracket 12 limits the force that can apply the tension roller 5b on the film. This also limits the frictional forces that the tension roller 5b can apply to the film.
  • the spring force with which the bracket 12 is held adjustable, which is not shown here.
  • a helpful contribution to the elimination of wrinkles or to the improvement of the smoothing is also provided by the profile of the tension roller 5b.
  • This profile consists of individual, circumferentially elastic studs 17, between each of which are wide distances (profile gaps). In this way, a rapidly increasing and decreasing tensile load is applied to the film located between the two rollers 5a and 5b, which optimizes the result.
  • the vertical extent of the region G that is actually required in the individual case can be easily determined by the person skilled in the art. It depends on the parameters set by the device and the film to be used (coefficient of friction between the reef bar and the film, between the film and the film, the speed of the stretch film over the load, the concrete geometry of the reef bar, the degree of horizontal and possibly vertical stretching, etc .) of the desired reliability, d. H. from the degree of security with which the skilled person wants to prevent overlapping creases from reaching the critical region K. As a rule, there is an optimal compromise between the required compactness of the reef bow on the one hand and a sufficiently reliable avoidance of overlap creases in the critical region K on the other hand.
  • the region G is located between the critical region K and the region ZH, in which the film supply 8 is alsziehffont accordion-like.
  • the bracket 12 in its altitude, d. H. in the vertical direction be kept adjustable on the reef bracket 1, while additionally / or alternatively the distance between the rollers 5a, 5b can be adjustable.
  • the result described above can also be achieved under certain circumstances by, for example, pivotally supporting the tension roller 5b and delivering it separately just before completion of the refining operation in such a way that it interacts with the refining roller 5a.
  • the preferred solution is designed as shown in the figures illustrating the preferred embodiment. Because in such an embodiment of the construction effort is kept low and also reduces the risk of error, which is approximately the result that it can come through the subsequent delivery of the tension roller 5b under unfavorable circumstances to an undesirable foil rope or the like.
  • rollers 5a and 5b must also be seen in Aufreffraum not absolutely accurate with each other. A certain, not significantly disturbing lateral function offset between the two rollers 5a and 5b is permitted.
  • the loosely deposited film located on the reef bows after impacting is first stretched in a substantially horizontal direction as a result of a movement apart of the reefing bows and reforgants made in a substantially horizontal direction as a function of the material to be packed.
  • the tensile force of the foil which is now stretched in a substantially horizontal direction, causes the overlapping creases 18 lying one above the other in the area ZH of the stretch foil reserve 8 loosely placed during the application process to be tight against the reef bows under considerable stress in the region ZH.
  • the tension roller 5b continues to be supported in its operating position on the bracket 12 mounted in a floating manner in the horizontal direction, in order to be so to maintain the smoothing effect in the region G between zones Z1 and Z2 even during the peeling operation.
  • the lower traction roller 5b is supported in its operating position advantageously on a bracket 12, which is seen in the horizontal direction fixed by the screw 14 and spring loaded in the horizontal direction over a held by a screw 13 compression spring so far that a pressure of the bracket 12th is realized on the pull roller.
  • the bracket may instead of such, preferably floating support be mounted spring-hinged.
  • the storage or the drive of the tension roller 5b such that these during Aufreffvorgangs accordingly on the reef motor 3 can be driven in Aufreffraum to ensure the difference in the peripheral speeds of the two rollers 5a and 5b and thus to achieve the desired smoothing in the G, the storage or the drive of the tension roller 5b, however, in addition to a freewheel is equipped, which allows the running of the pull roller 5b with the film in the withdrawal direction during the removal process.
  • the refining roller 5a and the tension roller 5b have almost the same circumferential speed.
  • a particularly low-friction, elaborately designed freewheel is not necessary here, since the frictional forces of the tension roller 5b or the freewheel are rather desirable, since it exerts a certain, albeit slight, braking effect on the film, which in turn now produces the desired smoothing effect the removal process has the consequence.
