  • Apparatus for removing binding tape from objects strapped with binding tape in particular coils.
  • - Coils are to be understood in the context of the invention Blechbunde, both hot coils and cold coils.
  • tie tape removers are known US 4,437,223 to remove the circumferential strapping of coils which are regularly handled by one or more ties.
  • Such binding tape removers generally have a traversing device to which a settable knife basket is attached.
  • a knife carriage In the knife basket a knife carriage is integrated.
  • a traction drive moves the knife basket between its working positions. The final end positions are indicated by inductive proximity switches.
  • the knife carriage is equipped with a lifting wedge and a cutting tool.
  • the Anhebekeil is moved on the respective coil surface and raises the respective binding tape to be removed, while then the powered cutting tool moves down and severed the binding tape.
  • the known binding tape removers are equipped with a search device.
  • This search device is usually a push-button that slides over the coil surface while the knife carriage is moving and feels the existing binding tapes. Only after the detection of such a binding tape is the way of a dependent control on the one hand the Anhebekeil moved against the tactile binding tape and raises this, while in the course of a sequential circuit down the separating tool for severing the raised binding tape down. Unsatisfactory with such tie tape removers is not only the fact that the search device is complicated and prone to failure, but beyond that each binding tape must be felt, as it were a separate operation, raised and cut, so that with several ties only a gradual binding tape removal is possible. This is time consuming and costly, beyond cumbersome and prone to failure. - Here the invention wants to remedy the situation.

  • a particularly simple and trouble-free working binding tape remover is realized, which not only works without a search button, but can also cut without a control for the cutting tool and the rest in a single continuous operation, all a coil strapping binding bands. This results in a largely maintenance-free and cost-minimized operation.
  • the invention provides that the Anhebekeil is designed as a step wedge with a leading opposite two-sided wedge surfaces Vertex and a passage slot in the middle of the wedge for the dipping into the passage slot cutting tool and in particular roller blade.
  • the V-tongue is particularly flat and adapted so that the present on the respective coil tie-downs are undercut and raised with certainty, in a first flatter and a subsequent second steeper step, so that the centrally arranged roller blade a perfect transection of the relevant Ensured tie ribbon. Because the roller blade is rotatably mounted about a bearing axis, which is arranged above the Anhebekeils and orthogonal to the feed direction of the Anhebekeils.
  • the knife carriage and the Anhebekeil in the knife carriage are suitably by means of a spring suspension stored at least the Anhebekeil is resilient against the respective coil surface.
  • This elastic system compensates for surface irregularities in the area of the coil surface.

  • the knife carriage may have wheels or rollers, with which it is movable on the coil surface. Furthermore, a separate hydraulic, pneumatic or electromechanical lifting and traction drive is provided for the knife carriage.
  • the lifting drive is required to lower the raised in the starting position in the knife basket knife carriage with the Anhebekeil against the respective coil surface and thus to transfer into working position. After completion of the binding band separation and reaching its end position, the knife carriage is raised again.
  • the traction drive generates the driving movement of the knife carriage on the respective coil surface and consequently the advancing movement of the Anhebekeils and the roller blade.
  • the end positions of the lifting and driving movements of the knife carriage can be monitored by means of inductive proximity switches.
  • the invention provides that the knife carriage has a subsequent to the Anhebekeil lower clamping bar, which under the feed movement of the Anhebekeils the band ends of the severed binding bands on the one band side moves underneath, and that the knife basket a Having upper clamping bar, which moves down in the end position knife carriage on the lower clamping bar, for example, down pivots and clamps resting on the lower clamping bar band ends.
  • the binding band clamping is also hydraulic, pneumatic or elktromechanisch, the operating conditions "clamped” or “solved” are displayed by inductive proximity switch.
  • the knife basket is moved with the severed and clamped ties for disposal through a scrap bucket.
  • the one or more severed ties are rolled up by means of a winder and stripped from these winder, so that they then fall into the scrap bucket.
  • the lower clamping bar preferably has a wedge-shaped bearing surface for the overlying band ends of the severed binding bands and the upper clamping bar with the wedge-like bearing surface on both sides cooperating round profiles, so that an optimal clamping effect is achieved.
  • the invention provides that the knife basket has on both sides of the basket in the longitudinal direction of the basket extending support rollers or wheels, which are pivotally mounted transversely to the longitudinal direction of the basket.
  • the knife basket fits the knife basket to the respective coil circumference
  • the binding coil strapping the coil in question properly held after their severance until the clamp from lower clamping bar and upper clamping bar clamped the resting on the lower clamping bar band ends.
  • a perfect holding the binding bands is achieved for the separation process, namely in the course of driving under and lifting the relevant binding bands and their separation by means of the separating tool or roller blade.
  • the support rollers or wheels can be arranged in pairs in, the knife cage pivotally mounted bearing cheeks.
  • the knife basket In order to prevent a displacement of the knife basket on the relevant coil during the raising and severing of the binding bands, the knife basket on the feed direction of Anhebekeil and roller blade opposite acting and length and height adjustable restraint on the front-side engaging behind the respective coil.
  • This restraint device can also be actuated hydraulically, pneumatically or electromechanically. It is released after the separation process, so that the knife basket can be lifted and moved into the scrap bucket position.
  • the knife basket has a basket length bridging the total distance formed by the binding tapes to be removed, and that the feed path of lifting wedge and roller knife is chosen to be greater than the maximum distance between the two outer tapes to be removed, so that in the course of a separation process with certainty all surrounding the coil concerned tapes are detected and severed.
