Definitions

  • the invention relates to a device for applying labels, in particular adhesive labels, to a workpiece, in particular an electrical and/or electronic component, the device having a linearly movable stamp with which a label that has been picked up can be applied to the workpiece, and wherein the device has a positioning aid that supports correct positioning of the workpiece.
  • Electrical and/or electronic components are used in a variety of ways, for example in control cabinets or other control devices. In order to simplify wiring of such electrical or electronic components, they are often provided with labels prior to assembly, which allow identification and comparison with circuit and or wiring diagrams.
  • Label printers are known for this purpose, which prepare the corresponding Eti chains and transfer them to an applicator that applies the labels to the components.
  • applicators have a stamp that can be moved linearly, at the front, free end of which is arranged a receiving device, also known as a transfer head, for the previously printed label.
  • the workpiece for example the electrical and/or electronic component, is positioned under the stamp, which then moves out and the label that has been picked up is stuck at the designated location. To do this, the workpiece must be correctly positioned in order to actually attach the label to the intended location.
  • a device of the type mentioned at the outset is characterized in that the positioning aid has at least two line lasers, which are aligned and arranged in such a way that they each emit a light fan in a plane that runs parallel to a displacement direction of the stamp, with the Cut fan of light.
  • the line lasers are arranged on a holder that is located in a region of a transfer head that is arranged on a free end of the stamp and receives the label for application to the workpiece.
  • the holder can be attached to the transfer head and move with it or, alternatively, be attached to a non-moving part of the device.
  • the line laser can be positioned radially outside of the transfer head, viewed from the stamp, ie in a position where there is enough free space available and the laser does not collide with other components of the transfer head.
  • the device has four line lasers, which are arranged and aligned in such a way that their light fans run parallel to one another in pairs.
  • the four line lasers preferably project lines onto a level below that of the transfer head, which lines run along the positions of the edges of the label during an extension of the stamp. This makes it possible to project the usually rectangular shape of labels onto the workpiece.
  • three line lasers can also be used, each of which is at an angle of, for example, 60° to one another, as a result of which a triangle is projected onto the workpiece—a shape that labels with warning notices, for example, often have.
  • the device is set up for applying labels to electrical or electronic components, in particular for use in switch cabinets.
  • components such as fuses, contactors, etc., which are regularly pre-labelled and used in switching cabinets, can be labeled in a wide variety of configurations without mechanical stops or attachment templates.
  • the figure shows:
  • FIG. 1 shows a schematic isometric view of a device for applying labels to a workpiece.
  • FIG. 1 shows a device 1 for attaching labels 4 to a workpiece, not shown here, in a schematic isometric representation.
  • the device 1 is also referred to as an applicator 1 in the following. It is subordinate to or integrated into a label printer, which is only indicated here on the right-hand edge of the figure.
  • the applicator 1 has a linearly displaceable, generally vertically arranged and downwardly extending plunger 2 .
  • the applicator can also be used in other orientations, in which the plunger 2 does not move downward but in a different spatial direction.
  • the directional indication "down" in this application denotes the direction in which the stamp 2 extends.
  • a transfer head 3 is attached to a free end of the stamp 2, which takes up a printed label 4 and fixes it with its adhesive surface facing down, for example with the aid of a vacuum.
  • the label 4 itself cannot be seen in FIG. 1 and is already positioned on the transfer head from below.
  • the arrow emanating from reference number 4 indicates its position.
  • the latter is positioned below the movable stamp 2 and the stamp 2 is extended until it encounters resistance or has reached the end of its travel.
  • the label is thus pressed with its adhesive surface on the surface of the workpiece and remains there, even if the stamp 2 moves back again.
  • the applicator 1 has a positioning aid according to the invention, which includes four line lasers 11 in the present case. These are mounted on a quadrant-shaped holder 12 which is arranged around the transfer head 3 . In the example shown, the holder 14 remains in the position shown, even if the transfer head 3 is lowered on the stamp 2. In an alternative embodiment, the holder can be mounted on the transfer head 3 so that it moves with the transfer head 3 downwards.
  • Each of the line lasers 11 spans a laser fan 13 lying in one plane, with the required opening angle of the laser fan depending on the travel path of the stamp 2 and the size of the label 4 .
  • an opening angle of about 10-30° is sufficient.
  • the line lasers 11 are arranged in pairs on the holder 12, with two of the line lasers 11 being mounted side by side.
  • the pairs of line lasers 11 grouped in this way are offset from one another by 90° on the holder 12.
  • the line laser 11 of a pair are each aligned so that their Laserfä cher 13 are in parallel planes to each other.
  • the planes of the laser fans 13 of the other pair are cut at an angle of 90° (in this exemplary embodiment).
  • a grid pattern of four lines 14 is projected onto a plane below the stamp 2, of which two lines 14 are parallel to one another and the other two lines 14 Li intersect at an angle of 90 °.
  • the plane that is projected on is usually one, as is the plane on which the label is stuck Normal plane to the direction of displacement of the punch 2, ie a plane that is perpendicular to the direction of displacement.
  • a rectangle is circumscribed which is just the size of the label 4 to be applied and is in its position. Both size and position of the rectangle are independent of the distance of the plane to the rest position of the transfer head 3 or to the holder 14. This means that the correct position and size of the label 4 is projected onto a workpiece regardless of the height of the workpiece is, although the line lasers 11 are mounted on the holder 14 radially farther apart than the edge of the label 4. In order to reach this, the plane of each laser fan 13 is aligned parallel to the displacement direction of the stamp 2.
  • the described arrangement of the line laser 11 makes it possible for the cutting lines between the laser compartments 13 to run precisely at the corners of the label, without the line laser 13 itself having to be positioned at these points. If a laser beam were used, not a laser fan, it would be difficult to position the laser in such a way that the light beam would run correctly along the displacement path of a corner of the label 4 without this leading to a problematic arrangement of the laser in the transfer head 3.
  • the line lasers 11 which are positioned radially outside half of the label 4 and whose laser fans 13 lie in a plane that is aligned parallel to the direction of displacement of the stamp 2, a correct projection of the outline or of contact edges on the work piece allows the lasers 11 is independent of the distance of the workpiece from the line. Therefore, the line laser 11 can either be stationary on the applicator
