Definitions

  • the invention relates to a protective device for planing machines for joining and dressing wooden workpieces with an organ for covering the knife shaft, which is attached to one side of the machine bed so as to be height-adjustable.
  • Planer protection devices are known in which the organ for covering the knife shaft is attached to a support head which is pivotally attached to one side of the machine bed via a lever linkage.
  • the cover element can be raised so that the workpiece can be pushed through.
  • the covering member is removed from the joining stop via the lever linkage, so that the workpiece can be carried out between the end of the covering member and the joining stop; a pressing force of the covering member onto the workpiece is applied by hand. After the workpiece has been pushed through between the joining stop and the end of the covering member, it remains in its position remote from the joining stop, so that the part of the knife shaft which is exposed there is not covered.
  • the invention has for its object to provide a planer protection device of the type outlined above, in which the organ for covering the knife shaft regardless of the position of the joining stop always exerts a horizontal pressure against the joining stop and a complete coverage of the knife shaft in ensures every position.
  • this object is achieved according to the invention in that the organ for covering the knife shaft there is a cover strip which is mounted horizontally displaceably in a guide member against a pressing force acting in the direction of the joining stop.
  • This protective device has the advantage over all previously known knife shaft covers that the cover strip always automatically adjusts itself to a position in which it is as close as possible to the joining stop, regardless of the position in each case. At the same time, pressure is always exerted on the workpiece in the direction of the joining stop.
  • the free end of the cover strip facing the joining stop carries a pressure shoe, from which an inlet beak protrudes, which lies in a plane running parallel to the work table and forms an acute angle with the joining stop.
  • the inlet beak facilitates the feeding of the workpiece when joining, since this gradually moves the pressure shoe and with it the cover strip against the pressing force away from the joining stop until the required gap width for pushing through the workpiece is reached.
  • the inlet beak in the pressure shoe can be pivoted about a horizontal axis lying transversely to the longitudinal axis of the cover strip into a position rotated by 90 °, in which it protrudes upward from the work table. In this position, rotated by 90 °, the upward-inclined inlet beak facilitates the feeding of workpieces for dressing work.
  • the workpieces press against the underside of the upward-facing infeed beak and raise it, and with it the cover strip connected to it, until the required gap height for pushing through the workpiece is reached.
  • the guide element for the cover strip has a horizontally arranged support plate, on which four guide rollers lying opposite one another in pairs are mounted, between which the cover strip is held displaceably in the direction of its longitudinal axis.
  • the guide rollers ensure a tilt-free longitudinal displacement of the cover strip.
  • the cover strip can be connected to a tracking device for automatic return to an adjustable rest position above the knife shaft. This opens up the possibility of dressing series parts or heavier workpieces, without the cover strip having to be raised again each time to push the workpiece through, since after each depression by the workpiece and its retraction it automatically returns to its set rest position.
  • the cover strip is interrupted in its central region by a hinge, by means of which the rear part of the cover strip pointing away from the joining stop can be folded down. It is advantageous if the hinge has a locking element for locking the rear part of the cover strip in a horizontal position in alignment with the front part.
  • a drive spring, a gas spring or an electronically controlled motor can be provided to generate the pressure force on the cover strip.
  • the cover strip When a drive spring is used to generate the pressure force, it is advantageously attached to the support plate and connected to the cover strip via a cable. It is advantageous if the cover strip carries a lockable stop element which is displaceable in the direction of its longitudinal axis and on which the cable pull acts.
  • the horizontal adjustment path of the stop bar in the direction of the joining stop can be adjusted via the stop element, both when using only the front partial area of the cover bar with the rear part folded down and over the entire area of the cover bar. In this way, when performing dressing work, it is possible to leave a small gap between the free end of the cover strip and the joining stop, so that frictional contact between the end of the covering strip and the joining stop is avoided.
  • the support plate is attached to a lifting device which is mounted on a carrier which can be attached to one side of the machine bed.
  • the lifting device can be connected to a weight relief device for the cover strip, so that only a fraction of the total weight has to be moved when the cover strip is lifted by hand.
  • the weight relief device can have a mainspring with adjustable preload, but it can also consist of a gas spring.
  • the lifting device has two vertical rods which are mounted in ball guide bushes attached to the carrier and are connected via a cable to the mainspring attached to the carrier for weight relief.
  • the ball guide bushes ensure trouble-free height adjustment of the cover strip without the risk of jamming or jamming.
  • the mainspring for the weight relief is attached to the carrier and can be accommodated in a housing that takes up little space and enables a compact design.
  • the lifting device has a carriage which is mounted on guide rails attached to the carrier via guide rollers, the gas spring acting on the carrier on the one hand and on the carriage on the other hand to relieve weight.
  • the cylinder housing of the height-adjustable gas spring can be connected in an articulated manner with its upper end to a lifting lever which is pivotably mounted on the carrier and on whose free end the support plate is supported.
  • the piston rod of this gas spring is articulated with its downward-facing end on a sliding plate which is arranged in a guide rail of the carrier so as to be vertically displaceable and lockable.
  • the piston rod of the height-adjustable gas spring is supported with its downward-pointing end on the carrier, while the housing of the gas spring is displaceable relative to the carriage and can be fixed thereon.
  • a support plate is provided for the guide member of the cover strip, it is possible to attach it to a swivel arm which serves as a lifting device and is attached to one side of the machine bed. This simplifies the retrofitting of planing machines already in use that are already equipped with a swivel arm.
  • the swivel arm receives the gas spring for generating the pressing force, which has a deflecting roller for a cable pull at the free end of its piston rod, which is guided over other deflecting pulleys in the manner of a pulley block and on the one hand on the swivel arm and on the other hand on the cover strip is attached.
  • This measure makes it possible to use a gas spring, the relatively small stroke of which generates a multiple of the displacement path for the cover strip due to the translation of the pulley block.
  • FIGS. 1 to 15 shows a top view of the preferred embodiment of the protective device according to the invention.
  • a carrier 14 is fastened to the longitudinal side 10 of the machine bed of a planing machine facing the operator, the work table of which is indicated by 12.
  • a lifting device 18 is attached, which in the exemplary embodiment of FIGS. 1 to 15 has two vertical rods 20 which are connected to one another at the lower end by a horizontal plate 22.

  • the inlet beak 40 is pivotably mounted in the pressure shoe 38 via a bolt 42 about a horizontal axis 44 lying transverse to the longitudinal axis 32 of the cover strip 30.
  • the inlet beak 40 has a handle recess 46 so that it can be swiveled by hand from its joining position shown in FIGS. 4 and 5 against the force of a compression spring 50 by 90 ° into the position of FIGS.
  • the inlet beak 40 is locked on the pressure shoe 38 by a not shown locking element.
  • the inlet beak 40 protrudes upward from the work table 12 and forms the angle ⁇ with it, so that a workpiece 46 can be inserted for dressing.
  • the inlet beak 40 consists of a material that is harder than the material of the pressure shoe 38. This ensures that premature wear of the Inlet beak 40 is prevented, while the sliding movements on the pressure shoe 38 are favored due to the softer material.
  • the cover strip 30 exerts a pressing force on the workpiece 46 via its pressure shoe 38 and thereby presses it against the joining stop 36.
  • the pressing force is generated by a drive spring 52, which has the shape of a spiral spring.
  • the drive spring 52 is fastened at one end to a bolt 54 which is screwed to the support plate 26 below the cover strip 30.
  • the other end of the mainspring 52 is attached to the inside of a cylindrical housing 56 which can be rotated to adjust the bias of the mainspring 52.

  • the two clamping jaws 66 sit on a common support bolt 68, the right end of which is designed as a handle 70 in FIGS. 11 and 12.
  • An arm 72 of a release lever 74 engages between the two opposite ends of the clamping jaws 66; the arm 72 is pivotally mounted on the support bolt 68 by means of a pin 76. If the release lever 74 is pressed by hand against the handle 70 from the clamping position of the stop element 64 shown in FIG. 11, the arm 72 according to FIG.
  • the drive spring 52 and the adjustable stop element 64 cause the cover strip 30 to be automatically moved back into the position in which the knife shaft 34 is covered to the maximum after each horizontal displacement when joining. At the same time, the mainspring 52 takes on the task of doing the necessary Apply pressure force to the workpiece 46 in the direction of the joining stop 36.
