Definitions

  • the invention relates to a device according to the preamble of claim 1 and a method for pressing on edge bands.
  • edge bands are attached to the narrow sides of panel-shaped workpieces, which are usually made of wood or wood substitutes. All panel-shaped workpieces have at least outer corner areas. With these, the attachment of edge bands across the corner is unproblematic, since two adjacent narrow sides can be approached separately with an edge band in case of doubt. Since rolls or rollers are usually used for pressing, such outside corners do not pose a problem. The situation is different if there are inside corner areas. With such workpiece geometries, it is impossible to press the edgeband into the corner area with a roller or cylinder.
  • the device according to the invention is used for pressing edge bands onto workpieces made of wood or wood substitutes, which have at least two workpiece sections which are angled relative to one another and form an inside corner.
  • the device according to the invention has an edge band feed and at least one main pressure roller, which can be rotated about a first axis of rotation, for pressing the edge band fed from the feed to the workpiece onto the narrow side of the workpiece.
  • the device according to the invention comprises a pressing element with two pressing surfaces which are angled relative to one another, in particular at an acute angle to one another. The latter are used to press the edging tape against the narrow side of the workpiece, especially in the area of the inside corner.
  • the pressing element is arranged on a first pivoting lever. This allows the pressing element to be pivoted by means of the first pivot lever in a pivot plane perpendicular to the first axis of rotation.
  • an edge band can be pressed into an inside corner of a workpiece by means of the pressing element.
  • the pressure roller can continue to lie against the edge band, so that the contact between the pressure element and the edge band is reduced to a minimum distance, which minimizes leaving marks on the edge band.
  • the device according to the invention is due the pivotability of the pressure element is able to run over the inner corner with a continuous edge band when coating the workpiece with an edge band and thus continue the coating process uninterrupted.
  • the pressure element can be pivoted around the pressure roller so that it is also available for moving into another inside corner.
  • the device according to the invention comprises a secondary pressure roller which is mounted on a second pivoting lever so that it can rotate about a second axis of rotation, the second pivoting lever being arranged in such a way that the secondary pressure roller can be moved by means of the second pivoting lever in a pivoting plane perpendicular to the first Axis of rotation can be pivoted.
  • the secondary pressure roller supports the main pressure roller when pressing the edge band onto the workpiece and can maintain contact with the edge band when driving over an inside corner, for example, when the main pressure roller has to be lifted off the edge band for a short time, thus ensuring that the pressure behavior is not impaired.
  • the secondary pressure roller can be advanced or lifted from the edge band at any time due to its bearing on the second swivel lever.
  • first pivoted lever and/or the second pivoted lever is/are mounted pivotably about the first axis of rotation.
  • this enables a particularly compact design of the entire unit.
  • the pressure element, the main pressure roller and/or the secondary pressure roller can then be moved as a unit on a single guide. This is advantageous since the main pressure roller and pressure element or secondary pressure roller must be carried along during the coating process anyway.
  • first pivoted lever and/or the second pivoted lever is/are dimensioned such that the pressure element and/or the secondary pressure roller is/are moved when the associated pivoted lever is pivoted on a path located radially outside the lateral surface of the main pressure roller .
  • the components arranged on the pivoting levers can be displaced independently of the position of the main pressure roller, without the main pressure roller impairing this movement.
  • the pivoting levers can be of different lengths, so that these two components do not impede one another when pivoting the secondary pressure roller and the pressing element.
  • the first pivoting lever is shorter than the second pivoting lever, so that the pressure element can be pivoted between the main pressure roller and any secondary pressure roller that may be present.
  • step f. a step g. is carried out, in which the second pressing surface of the pressing element presses the second edge band section against the narrow side of the second workpiece section.
  • the folded second edge band section is already pressed against the workpiece in the inside corner. It is not necessary to set down the pressing element, since it only has to be turned over its tip.
  • the pressing element when pressing the second edge band section follows the main pinch roller. This ensures that proper pressing also takes place in the sections on the second edge band section that the main pressure roller cannot reach. In other words, the trailing can take place until a section on the second edge band section is reached against which the main pressure roller can already press.
  • the secondary pinch roller abuts against the first edge band section trailing the main pinch roller. It is then possible that the main pressure roller is lifted off the edge band and the secondary pressure roller remains in contact with the corresponding edge band section.
  • a device 1 according to the invention is shown schematically.
  • a feed 11 for edge bands 3 is preferably attached to a carrier 10 .
  • the device 1 according to the invention comprises a preferred also arranged on the carrier 10 main pressure roller 13, which is rotatably mounted about a first axis of rotation A.
  • 12 designates an activation device to prepare the edgeband 3 for joining to the workpiece.
  • the activation device 12 can be an adhesive application unit, but it can also be a laser or a hot air source or the like.
  • the activation device 12 is preferably also arranged on the carrier 10 .
  • the device 1 according to the invention comprises a pressing element 17 which is arranged on a first lever 16 .
  • the first lever 16 is—preferably on the carrier 10—mounted so that it can pivot in the direction of the arrow P2, most preferably about the axis A.
  • the pressing element 17 has a first pressing surface 17b and a second pressing surface 17a. These two contact surfaces 17a and 17b are angled towards one another and in particular form an acute angle with the tip 17c.
  • the device 1 according to the invention can also have a secondary pressure roller 15 which, for its part, is mounted on a second lever 14 such that it can rotate about an axis B.
  • the second lever 14 can be pivoted about an axis that is preferably mounted on the support 10, as indicated by the arrow P1.
  • the pivot axis of the lever 14 preferably corresponds to the axis A.
  • the workpiece 2 has two workpiece sections 21, 22, between which an inner corner 20 is formed.
  • This is conveyed through the feed 11 in the direction of the narrow side of the workpiece 2, activated by the activation device 12 in the manner described above and pressed against the narrow side of the workpiece 2 by means of the main pressure roller 13.
  • the section 22 of the workpiece 2 is coated with the edgeband 3 .
  • the edge band 3 is moved up to the narrow side 22 of the workpiece 2 by means of the feed 11 and pressed against the narrow side 22 with the pressure roller 13 .
  • the unit consisting of pressure roller 13 and pressure element 17 is then moved relative to the workpiece, in the X direction in the example shown.
  • the pressure roller 13, which rotates about the axis A, runs over the supplied edging strip 3 and presses it against the narrow side 22 over the course of the latter.
  • a secondary pressure roller 15 can also be brought to bear on or to contact the edge band 3 by pivoting the lever 14 in order to support the pressing process or to perform a re-pressing function in an area of the edge band that the pressure roller 13 has already passed.
  • the pressing element 17 is pivoted by pivoting the lever 16 so that its first pressing surface 17b comes to rest on the edging strip 3, more precisely the edging strip section 3b, which rests on the narrow side 22 of the workpiece 2.
  • the relative movement between the workpiece 2 and the unit 10 provides ensuring that the edge band 3 is pushed and pressed into the corner 20 of the workpiece 2 by means of the pressing element 17, as is shown in figure 6 is shown.
  • the entire unit or the overall carrier 10 is from the previously in the Figures 2 to 4 shown horizontal position in one of the Figures 6 to 8 shown vertical position has been pivoted.
  • the preferred pivoting axis is axis A, about which the pressure roller is also pivoted.
  • the second contact surface 17a now rests against the section 3a of the edge band.
  • the secondary pressure roller 15 that may be present remains in contact with the first section 3b of the edge band 3 in this situation, so that the main pressure roller 13 can be released from the system with the section 3b and moved into the system with the section 3a.
  • the pressure element 17 remains with its second pressure surface 17a in contact with the edge band section 3a while performing the above-mentioned relative movement in the Y direction until the section of the edge band 3a between the inner corner 20 and the Point at which the main pressure roller touches the edge band 3a for the first time is pressed against the narrow side 21 of the workpiece 2.
  • the pressing element 17 follows the main pressing roller. This situation is in figure 8 shown.
  • the pressure element 17 can be removed from the position shown in figure 8 illustrated trailing position in a leading position, in which the contact surface 17b then again rests against the edge band section 3a, are pivoted, and with reference to the Figures 5 to 7 The process described is then repeated accordingly.
