Definitions

  • the invention relates to a feed and tensioning device for a strapping to be tensioned around a package, which can first be pushed forward with a pair of wheels that receive the strapping force-fittingly between itself in a band guide that encloses the package to be strapped and then with a fixed front end of the band by reversing the direction of rotation of the Wheels p aares can be brought into contact with the package by pulling back and can then be tensioned with a special tensioning wheel with lower feed speed and greater force.
  • the pair of wheels for advancing and retracting the band and the tensioning wheel are driven by a single motor, but a reduction gear is provided between the pair of wheels for advancing and retracting the strapping and the tensioning wheel, so that the tensioning wheel with a lower speed and greater force turns.
  • the tension wheel is partially wrapped around by the strapping so that the tensioning wheel frictionally engages the strap during tensioning.
  • a strap guide is assigned to the tensioning wheel, so that when the strap is pushed forward, the strapping strap only rests against the inside of the strap guide and does not come into contact with the tensioning wheel.
  • the invention has for its object to provide a feed and tensioning device of the type described in the introduction, in which such disadvantages are avoided and the pushing, pulling back and tensioning of the strapping can be carried out in a simple manner and when tensioning the strapping the drivable tensioning wheel accordingly the increasing tensile stress in the strapping is applied to the strapping force, without permanently deforming the strapping, which is made of plastic in particular, during tensioning.
  • the tensioning of the strapping is carried out with a pair of wheels, of which one wheel is designed as a rotating wheel and the other wheel is rotatable in the tensioning direction with an associated motor and is mounted with its axis in a pivot lever such that when Tension the strapping the drivable and partially wrapped by the strapping tension wheel against the against The strapping band supporting the running wheel with an increasing compressive force corresponding to the increasing tensile stress in the strapping band.
  • a tensioning device is created in a simple manner, with which a very high tension in the strapping band can be achieved, because when the strapping band is tensioned, there is no fear of the strapping band slipping on the tensioning wheel, since the driven tensioning wheel with increasing contact pressure corresponding to the increasing tension in the strapping band is pressed against the strapping that supports itself against the rotating wheel.
  • the direction of rotation of the driven tensioning wheel runs in such a way that a force component occurs in the sense of pushing the two wheels apart, but this force component is smaller than the contact pressure caused by the pivoting lever due to the strap tension. Due to the pivotable mounting of the tensioning wheel on the pivoting lever and the direction of rotation of the tensioning wheel, it is thus achieved in a simple manner that the force component resulting from the direction of rotation of the tensioning wheel is opposed to the contact pressure caused by the pivoting lever by the belt tension, so that these two forces do not occur add to such a force and cause destruction or deformation of the strapping, which is made in particular of plastic.
  • the force component resulting from the direction of rotation of the tensioning wheel can be very small, since it is sufficient for the gentle treatment of the strapping, which is made in particular of plastic, if the pressing force is not increased by the direction of rotation of the tensioning wheel.
  • the drivable tensioning wheel can be provided on the metallic outer surface with a cord or the like which increases the coefficient of friction. This easily prevents the strapping from slipping on the outer surface of the drivable tensioning wheel.
  • the circumferential surface of the rotating wheel that comes into contact with the strapping band can be formed by an abrasion-resistant, soft-elastic pad.
  • the drivable tensioning wheel presses with the strapping into the abrasion-resistant, soft-elastic support of the idler wheel, so that a large-area support is achieved both on the drivable tensioning wheel and on the idler wheel, at the same time in a simple manner damaging the, in particular Plastic existing, strapping can be avoided.
  • the drivable tensioning wheel can at the same time form a deflection for the strapping band and the part of the strapping band leading from the drivable tensioning wheel to the package can run at least approximately parallel to the pressing direction of the drivable tensioning wheel mounted on the swivel lever.
  • the tensioning wheel which can be driven in the strapping band pushes the drivable tensioning wheel against the strapping band which is supported against the moving wheel with increasing contact pressure.
  • the pressing of the drivable tensioning wheel mounted on the swivel lever against the strapping band supported by the rotating wheel can take place against the action of a spring acting on the swivel lever. It is thereby achieved in a simple manner that the drivable tensioning wheel mounted on the pivoting lever strives to assume a position in which the contact pressure is low or zero.
  • the drivable tensioning wheel mounted on the swivel lever can be held with the spring in a basic position before tensioning when the strapping band is advanced, in which the drivable tensioning wheel and the associated idler wheel for free advancement of the strapping band with a distance exceeding the thickness of the strapping band are arranged to each other.
  • the strapping tape can thus be freely passed between the drivable tensioning wheel and the associated idler wheel when advancing.
  • the swivel lever carrying the drivable tensioning wheel can rest against a fixed stop surface with an adjustable stop.
  • the distance between the drivable tensioning wheel and the idling wheel, which exceeds the thickness of the strapping band can be adapted in a simple manner to the respective requirements for free advancement of the strapping band.
  • the strapping between the receiving pair of wheels for advancing and retracting the strapping can be formed by a pushing and retracting wheel which can be driven in both directions of rotation with its own motor and a rotating wheel.
  • the pair of wheels for advancing and retracting the strapping is advantageously formed by a drivable advancing and retracting wheel and a rotating wheel, the advancing and retracting wheel having its own motor which can be effective in both directions of rotation.
  • the co-rotating wheel cooperating with the drivable feed and retraction wheel can also form the co-rotating wheel for the drivable tensioning wheel.
  • the rotating wheel thus interacts in a simple manner with the drivable feed and retraction wheel and with the drivable tensioning wheel.
  • the drivable feed and retraction wheel can have a polished, metallic outer surface.
  • the drivable advancing and retracting wheel thus has a small coefficient of friction, so that only low advancing and retracting forces can be transmitted with the drivable advancing and retracting wheel.
  • This force is sufficient to advance the strapping band into the band guide which surrounds the package to be strapped at a distance. Furthermore, this small force is sufficient to pull the strap back while the front strap end is being held, so that the strapping comes into contact with the package and the tensioning wheel. Furthermore, this force is sufficient to bring the drivable tensioning wheel mounted on the swivel lever into abutment against the strapping band, which is supported against the rotating wheel.
  • the further retraction of the strap i.e. the tensioning of the strap is now carried out by the drivable tensioning wheel, the drivable advancing and retracting wheel slipping on the strapping strap.
  • the rotating wheel can be rotatably mounted on the one swivel arm of a rocker and can engage a spring on the rocker, under the action of which the rocker is held in a basic position in which the rotating wheel rests non-positively against the strapping band which is supported on the drivable advancing and retracting wheel .
  • the rocker that rotatably supports the rotating wheel is thus held in the basic position the frictional wheel rests non-positively against the strapping supported on the driven feed and retract wheel.
  • the swivel lever carrying the drivable tensioning wheel and the rocker carrying the rotating wheel can be pivotably mounted on a common bearing journal.
  • both the pivoting lever carrying the drivable tensioning wheel and the rocker carrying the idler wheel are pivotably mounted on a single journal.
  • the rotating wheel mounted on the rocker can, when the strapping is tensioned, be converted into a release position against the action of the spring by the contact pressure coming from the drivable tensioning wheel and acting on the rotating wheel, in which the drivable advancing and retracting wheel and the associated rotating wheel are arranged for free tensioning of the strapping at a distance from one another which exceeds the thickness of the strapping.
  • a stop can be assigned to the rocker to limit the pivoting movement into the release position. This prevents the rocker from pivoting too far beyond the release position in a simple manner.
  • the rocker will come on when the release position is reached.
  • Actuable switch with timing relays for switching off the motor from the tensioning wheel can be assigned.
  • the rocker actuates a switch with a timing relay that switches off the motor for the tensioning wheel.
  • the time relay can be adjusted in a simple manner, so that after the switch is actuated, a predetermined period of time passes until the motor of the tensioning wheel is switched off. This period of time thus determines the magnitude of the tension that is generated in the strapping band. The longer the time span, the greater the tension in the strapping band.
  • the rocker can also be assigned a force storage which can be loaded in the pivoting direction and is provided with an adjustable preload, and a switch which can be actuated when the release position is reached for switching off the motor from the tensioning wheel.
  • a precise setting of the tension in the strapping band is achieved in a simple manner, since before the release position is reached, the pivoting movement of the rocker must take place counter to the action of an energy store, the force of which can be adjusted. Reaching the release position is thus dependent on the tension in the strapping band, so that the switch for switching off the motor from the tensioning wheel is actuated only when the desired tension in the strapping band is reached.
  • the energy storage which can be loaded by the rocker in the pivoting direction can be formed by a helical compression spring which is supported on one end against a piston which is in contact with a stop and is in active connection with the rocker and on the other against a slide which is adjustable in the loading direction.
  • the helical compression spring forming the energy accumulator can thus be easily adjusted to the desired pretension and thus the tension can be brought to the desired size in the strapping.
  • the adjustable slide bearing against the helical compression spring can have on its side facing away from the helical compression spring a wedge surface for engaging a ball, which can be adjusted with a threaded spindle transversely to the direction of loading of the helical compression spring on the wedge surface of the slide. With the threaded spindle running transversely to the direction of loading of the helical compression spring, the ball on the wedge surface of the slide can thus be adjusted and the desired preload can thus be applied to the helical compression spring in a simple and reliable manner.
  • the feed and tensioning device shown in the drawing for a strapping band 10 to be tensioned around a package has a pair of wheels 11, 12 which receive the strapping band non-positively between it and with which the strapping band 10 surrounds the package to be strapped at a distance , tape guide not shown is advanced. By reversing the direction of rotation of the pair of wheels 11, 12, the strapping can then be held against the Package be brought. After putting on the strapping. Bandes 10 against the package can then be provided with the required tension with a special tension wheel driven by itself.

  • the drivable tensioning wheel 13 also forms a deflection for the strapping band 10, the part of the strapping band 10 leading from the drivable tensioning wheel 13 to the package running at least approximately parallel to the pressing direction of the drivable tensioning wheel 13 mounted on the pivoting lever 15. It is thus achieved in a simple manner that, with the contact force increasing in accordance with the increasing tensile stress in the strapping band, the tensioning wheel 13 is pressed against the strapping band 10 which is supported against the rotating wheel 12, so that there is no fear of the tensioning wheel 13 slipping on the strapping band even with increasing tension is.
  • the direction of rotation of the driven tensioning wheel 13 is such that a force component occurs in the sense of a pressing apart of the two wheels 12, 13, but this force component is smaller than that of the pivot lever 15 is the contact pressure caused by the belt tension.
  • the force component can be very small, since it is important that the contact pressure caused by the swivel lever 15 due to the belt tension is not also increased by the force component caused by the direction of rotation of the tensioning wheel 13.
  • the drivable tensioning wheel 13 is on its metallic one. Shell surface 16 with a cord or the like, not shown, increasing the coefficient of friction, or the like. Mistake. Furthermore, the circumferential surface 17 of the rotating wheel 12 which comes into contact with the strapping band 10 is formed by an abrasion-resistant, soft-elastic pad 18.
  • the tensioning wheel 13 is pressed against the strapping band supported by the rotating wheel 12, the tensioning wheel 13 with the strapping band 10 lying thereon is pressed into the abrasion-resistant, soft-elastic support 18, so that a large-area contact of the strapping band 10 both on the rotating wheel 12 and on the tensioning wheel 13 he follows. Damage to the strapping 10, in particular made of plastic, is thus avoided in a simple manner.
