Definitions

  • the present invention relates, on the one hand, to a tool holder head for a cutting plotter comprising a first and a second tool holder which are configured to accommodate a first and second tool, respectively, wherein the tool holder head is adjustable between a first position of use, in which the tool holder head is equipped to perform a treatment using the first tool, and a second position of use, in which the tool holder head is equipped to perform a treatment using the second tool.
  • the present invention relates to a cutting plotter provided with such a tool holder head.
  • the respective cutting plotter is preferably a computer-controlled (CNC) cutting plotter for cutting and creasing material.
  • the respective cutting plotter is a computer-controlled (CNC) roll-fed cutting plotter.
  • the known computer-controlled (CNC) cutting plotters such as for example the roll-fed cutting plotters, are used to treat, such as for example cutting or creasing, material, such as for example (cutting) films, paper, box or corrugated cardboard, and the like.
  • the treated material can then be used for both decorative purposes, for example cut-out figures or characters for decorating objects, and functional purposes, for example assemblable cardboard boxes.
  • Cutting plotters treat the material by moving a tool holder head containing a tool across a work surface in a controlled manner, based on instructions or commands from a processing unit, generally in accordance with a predetermined pattern.
  • a processing unit generally in accordance with a predetermined pattern.
  • the person skilled in the art may opt to fit a different type of tool to the tool holder head.
  • there are two fundamental treatments namely cutting out a desired shape by means of a cutting knife and creasing the material by means of a so-called creasing tool, which means that one or more grooves or fold lines are produced in a sheet of material in order to be able to fold the respective material more easily and produce the desired shape.
  • a large number of the known cutting plotters require the manual fitting of a different type of tool to the tool holder head if the type of treatment is to be changed, which may have a negative impact on the quality of the treatment, due to the fact that the relative position of the treatment end of the newly fitted tool with respect to a reference position of the tool holder head is different compared to the previous tool.
  • the processing speed is also negatively affected if the tool has to be changed manually.
  • a tool holder head which is configured in this way makes it possible to automatically switch between the respective tools, based on the set pattern.
  • Such a tool holder head is used by the company Graphtec on their flat-bed cutting plotter.
  • the respective tool holder head comprises two independently operating systems which are movable up and down and which are configured to each move a tool holder up and down.
  • a drawback of a tool holder head which is designed in this way is the fact that the system used to move both tool holders up and down is relatively expensive and occupies a large amount of space.
  • the object of the present invention is to provide a tool holder head for a cutting plotter, preferably a roll-fed cutting plotter, which makes it possible to select a first or second tool, depending on the treatment to be performed, in an easy, quick and precise manner, in order to be able to carry out a specific treatment in an automated manner, in particular based on instructions which are transmitted by means of computer software suitable for the purpose.

  • a tool holder head configured in this manner, it is possible, when used in a cutting plotter, to switch quickly and accurately between the tools fitted in the tool holder.
  • a tool holder head configured in this way is compact and less expensive, since no separate mechanism is required to move the second tool holder, preferably up and down, since, in the coupled state, the latter follows the movement of the first tool holder.
  • the first tool holder is configured to perform a rotating movement and an up and down movement, and the second tool holder only follows the up and down movement.
  • the first tool holder is configured to rotate in the first position of use in order to allow the tool fitted in the tool holder to co-rotate when the treatment is being performed, so that the tool is in each case situated in the correct position, or to allow the tool holder to rotate to a well-defined position, so that it can be coupled to the second tool holder.
  • the innovative aspect of the respective tool holder head is the fact that the rotating movement of the first tool holder can be used to select the second tool, so that said second tool can perform a treatment.
  • the tool is preferably a cutting tool or a creasing tool.
  • the creasing tool usually consists of a thin, rounded bar which presses on the surface of the material, preferably cardboard, in order to produce the desired fold lines.

  • a drag knife is not driven, the knife follows the rotation of the cutting movement since the knife is mounted and the tip of the knife is situated slightly behind the centre of the mounting (eccentric). As a result, the tip of the knife is situated behind and follows the cutting movement.
  • Rotation of the first tool holder is effected by means of a motor, preferably a DC motor, with the encoder providing the feedback.
  • the motor and first tool holder have a toothed belt disc, both are connected via a toothed belt.
  • the first tool is the cutting tool and the second tool is a creasing tool.
