Definitions

  • the invention relates to a feed device for strapping tapes in strapping machines with a driven feed roller and a pressing device cooperating therewith, which push the strapping strap through a strap channel against a stop.
  • the strapping is guided through a band channel which surrounds the package to be strapped in a ring.
  • the strapping runs against a stop, which is designed as a switch and stops the band feed.
  • a stop which is designed as a switch and stops the band feed.
  • the belt is advanced a little further and forms a loop in the belt channel when its front end is stopped by the stop switch.
  • Such loops in the band channel give rise to faults and can lead to the fact that proper strapping can no longer be produced with the band end remaining in the band channel.
  • the object of the invention is to design a feed device for strapping tapes in such a way that no loops form in the tape channel or loops which form are immediately removed again after their formation.
  • This object is achieved with the invention by means of a release lever which can be moved by a band loop which forms in the band channel and which lifts the pressing device off the feed roller.
  • This configuration has the advantage that a strap loop created in the strap channel by the trailing drive behind the feed roller eliminates itself by its creation, since the strapping due to its elasticity tends to return to its stretched position, and in the gap between the feed roller and Pressing device slides back to the supply roll as soon as the loop has lifted the pressing device off the feed roll via the lever. As a result, the strapping always takes up a completely stretched position in the band channel.
  • the release lever is moved by a band guide bar which covers part of the band channel and is deflected by the band loop which is being formed.
  • This configuration has the advantage that the strapping does not lose its lateral and upper guidance even in the area of the loop that forms.
  • the release lever can be a pivot lever that removes the pressing device against the pressure of a spring from the feed roller. It is possible to choose the lever ratio so that the pressure device can be lifted from the feed roller against the action of its relatively strong pressure spring, which is necessary for the perfect tape feed.
  • the pressure device can be mounted on a spring-loaded pressure lever, which has a stop on which the release lever acts.
  • the release lever itself covers part of the band channel and is acted upon directly by the band loop that is formed.
  • the release lever is then expediently designed as a band guide strip itself.
  • the release lever is also expediently arranged directly behind the feed roller according to the invention.
  • 10 designates a feed device according to the invention, with which a strapping band 11, for example a steel band or a plastic band, is advanced through a band channel 12, which surrounds the package to be strapped in a ring, of which only the first in the drawing Is shown piece that directly adjoins the feed device 10.
  • a strapping band for example a steel band or a plastic band
  • the feed device consists of a feed roller 13, which is driven by a drive (not shown here) in the direction of arrow 14, and of two loosely running pressure rollers 15 and 16, which form the pressure device and are rotatably mounted on a pressure lever 17.
  • the pressure lever 17 is pivotally mounted on a pin 18 and is under the action of a pressure spring 19, which strives to pivot the pressure lever 17 counterclockwise and press the pressure rollers 15 and 16 against the feed roller 13.
  • the strapping 11 is guided between the feed roller 13 and the pressure rollers 15 and 16 and is supported by a rear extension 20 on the bearing block 21 of the pressure rollers 15 and 16 and guided into the band channel 12.
  • the belt channel 12 has a U-shaped cross section in its front part shown here and is open towards the drive roller. It is covered behind the drive roller by a tape guide strip 22, which is pivotally mounted at one end 23 on a pin 24 in the machine housing. With its other, free end 25, the band guide strip 22 presses against a support roller 26, which is rotatably mounted on the free end 27 of a release lever 28.
  • the release lever 28 is a pivot lever, which is mounted with a shaft 29 in the machine housing and presses with its short, other end 30 against a roller pin 31, which is located on the carrier 21 for the pressure rollers 15 and 16 and is located on a pressure surface 32 on rolls the lower end 30 of the release lever 28.
  • the feed roller 13 continues to run for at least a short time.
  • the band guide strip 22 is pivoted outward about its pin 24 in a clockwise direction. It presses on the support roller 26, whereby the release lever 28 is pivoted about its shaft 29 counterclockwise.
  • the lower end 30 presses on the roller pin 31, which in this case rolls on the underside 32 of the release lever 28.
  • the pressure lever 17 is pivoted clockwise about its pivot pin 18, and the pressure rollers 15 and 16 are lifted off the feed roller 13. This state is shown in the drawing in solid lines.
  • the pressure spring 19 which strives to press the pressure rollers 15 and 16 again against the feed roller 13 and at the same time pivot the release lever 28 clockwise back into its starting position, the band guide strip 22 being simultaneously pushed back into its starting position, which pushes the strapping back into the strap guide channel 12.
  • the band guide bar 22 can also be under the action of a torsion spring which is placed around the pin 24 and tends to pivot the band guide bar 22 counterclockwise.
  • the invention is not restricted to the exemplary embodiment.
  • a pressure rail can of course also be used, and it is also possible to design the release lever instead of as a pivoting lever as a displaceable part which separates the pressure device from the feed roller. This does not exceed the scope of the invention.
