Definitions

  • the invention relates to a pressure device for a processing machine, preferably a woodworking machine, in particular a moulder, according to the preamble of claim 1.
  • a pressure element in the form of a pressure shoe in the direction of transport of the workpieces to be machined, which presses the workpieces to be machined against a corresponding guide or support during transport through the machine.
  • the pressure element must in a certain Ab Stand to the flight circle of the processing tool to be optimally effective. If the processing tool is exchanged for another processing tool with a different flight circle diameter, then the pressure element must be adjusted in a complex working process. The pressure element must be readjusted not only in the horizontal but also in the vertical direction. This cumbersome adjustment is not only complex and difficult, but also time-consuming.
  • the invention has for its object to design the generic pressure device so that the pressure element can be easily and relatively quickly adjusted relative to the machining tool.
  • the pressure element can be adjusted horizontally and vertically at the same time in a single adjustment process, since it is adjusted obliquely to the direction of transport of the workpieces relative to the processing tool.
  • the adjustment direction or adjustment plane of the pressure element is provided in such a way that the pressure element in processing tools with different flight circle diameters is brought into an at least approximately optimal position relative to the processing tool.
  • the adjustment of the pressure element can be carried out easily and, above all, extremely time-saving. Further features of the invention result from the further claims, the description and the drawings.
  • the pressure device is provided in a woodworking machine, preferably a moulder, and is arranged in the area of the processing tools of this woodworking machine.
  • 1 shows, as a woodworking tool, a cutter head 1 which is rotatably driven about a horizontal axis 2. Along its circumference, the cutter head 1 is provided with knives (not shown) with which the woods which are passed in the direction of the arrow 3 below the cutter head are processed.
  • the chips generated when processing the wood are removed from the suction hood 4, which covers the cutter head.
  • the suction hood 4 is fastened on a carrier 5 which is mounted on a pivot axis 6. It is pivotally mounted in side walls 7 of a cover 8.
  • the carrier 5 is fork-shaped and has two legs 9 and 10 with which it sits on the pivot axis 6. Both legs 9, 10 are connected to one another by a cross member 11, the upper side 12 (FIG. 1) facing away from the pivot axis 6 forms a reference and adjustment surface for the suction hood 4. It has one on the top 12 of the Cross member 11 resting adjustment part 13 which protrudes at an angle from the wall of the suction channel 14.
  • the adjustment part 13 - like the cross member 11 - is plate-shaped. It is fastened to the cross member 11 with screws 15, which are only indicated in FIG. 1.
  • elongated holes are provided for the passage of the screws 15, which extend perpendicular to the longitudinal direction of the adjustment part 13 or the cross member 11 or to the axis of rotation 2 of the cutter head 1. These elongated holes are provided in order to be able to adjust the suction hood 4 relative to the carrier 5 after loosening the screws 15 in order to adapt to cutter heads 1 of different diameters.
  • an adjustment spindle 16 is mounted on the adjustment part 13 and can be rotated with a handle 17.
  • the adjusting spindle 16 projects through a bearing part 18 projecting transversely from the adjusting part 13 and is held in the cross member 11.
  • a pressure element 20 in the form of a pressure shoe is mounted on the rear wall 19 of the suction hood 4 in the transport direction 3. It has a pressing surface 21 which is inclined forward and downward in the transport direction 3, onto which the woods to be processed run in front of the cutter head 2 in the direction of arrow 3 and are pressed against the transport path (not shown) of the woodworking machine during processing.
  • the pressure element 20 has a tip or edge 22 on its front side in the direction of transport 3 of the wood, which has a predetermined distance from the flight circle of the cutter head 1 in a known manner.
  • the pressure element 20 is pivotally supported on the suction hood 4 to a limited extent about an axis 23. Fig.
  • the pressure element 20 in its end position, in which it is pressed by a spring (not shown).
  • the pressure element 20 has only a relatively small swivel path, so as not to impair the pressure effect on the wood to be processed.
  • the pressure element 20 is loaded in the direction of the cutter head 1 by the spring. If the wood to be processed has greater differences in thickness, then the pressure element 20 can be pivoted slightly against the suction hood 4 against the spring force. It has been shown that this damping device reliably prevents the entire exhaust hood 4 from oscillating or vibrating.
  • the suction hood 4 with the carrier 5 itself is also spring-loaded in a known manner, so that these parts can also pivot away in the case of larger differences in thickness of the wood to be processed.
  • the spring force of the suction hood and the carrier is, however, considerably greater than the spring force of the pressure element 20.
  • the pressure element 20 is pivoted away without this having an effect on the suction hood 4.
  • considerable noise reduction is achieved when processing the woods, because the suction hood 4 is stationary with the support 5 and at most the pressure element 20 moves relative to the suction hood 4.
  • the edge 22 of the pressure element 20 must be adjusted relative to the flight circle in order to achieve an optimal effect. In order to make this adjustment possible, it is only necessary to loosen the screws 15 and then to use the adjusting spindle 16 to adjust the suction hood 4 with the pressure element 20 mounted thereon relative to the carrier 5.
  • the upper side 12 of the cross member 11 of the carrier 5 allows an accurate and exact adjustment of the pressure element 20.
  • the top 12 is inclined at such an angle to the horizontal that when the suction hood 4 is moved in the direction of the arrow 24, the edge 22 is not only adjusted horizontally but also vertically relative to the cutter head 1. Depending on the flight circle diameter, the edge 22 must not only be adjusted in the horizontal direction, but also in the vertical direction. As a result of the inclined position of the upper side 12, only a single adjustment process is necessary for these two adjustments. In order to achieve an optimal adjustment of the edge 22 of the pressure element, the upper side 12 lies at an angle ⁇ of approximately 40 ° to 50 ° to the horizontal (FIG. 1).
  • the edge 22 of the pressure element 20 can be optimally adjusted to the respective position in the different flight circle diameters in a single adjustment process. Since the user of the suction hood thus only has to carry out a single adjustment process by means of the adjustment spindle 16, he can bring the pressure element 20 into the respectively required position without difficulty.
  • the suction hood 4 is provided to adjust a chip guide plate 25 as a function of the flight circle diameter.
  • the chip guide plate 25 lies at a distance from the wall 19 of the suction channel 14 and, together with it, delimits the insertion opening 26 through which the chips produced during woodworking reach the suction channel 14.
  • the chip guide plate 25 is articulated on the carrier 5 with a hinge 27. As shown in FIG. 2, the chip guide plate 25 is bent up at one end 28 opposite to the cutter head 1. This bent end 28 forms one Baffle, which is provided with a curved track 29 with which a control pin 30 is assigned.
  • the cam track 29 is curved and is designed as an elongated opening in the guide plate 28.
  • the control pin 30 is provided on the suction hood 4 and engages in the cam track 29. Together with the control pin 30, it forms a forced control for the chip guide plate 25. If the suction hood 4 with the pressure element 20 is adjusted in the manner described by means of the adjusting spindle 16 relative to the carrier 5, the chip guide plate 25 is simultaneously adjusted by this forced control 29, 30.
  • the cam track 29 is arranged such that the chip guide plate 25 is pivoted away from the axis 2 of the cutter head 1 as soon as the pressure element 20 is removed from the axis 2. Conversely, the chip guide plate 25 is pivoted against the cutter head 1 when the pressure element 20 is set closer to the axis 2 of the cutter head 1.
  • the position of the chip guide plate 25 is automatically coupled to the position of the pressure element 20 relative to the cutter head 1, so that the insertion opening 26 into the suction channel 14 always has the optimal cross section.
  • the pressure element 20 optimally adjusted to the respective flight circle diameter of the cutter head 2 by the adjustment of the suction hood 4, but at the same time the chip guide plate 25 is also adjusted to the respective optimal position. Separate settings for the chip guide plate are therefore not necessary.
  • the described suction hood allows an extremely simple, yet very reliable adjustment to adapt to the respective flight circle diameter of the cutter head 1, while at the same time care is taken to ensure that the chip guide plate 25 also assumes its required optimal position during this adjustment. Incorrect settings are excluded.
