Definitions

  • the invention relates to a sealing plate for a vacuum block for fixing workpieces on a Fixierbalken or fixing table using negative pressure, wherein the sealing plate is clamped on at least one contact surface of the block suction and has at its periphery a sealing lip.
  • Vacuum blocks are generally known in tensioning systems and are typically used to make plate-like workpieces, e.g. Wood panels or the like to clamp on a processing machine.
  • This processing machine has a fixing table or more Fixierbalken on which usually sit a plurality of vacuum blocks and this rests on the workpiece to be machined.
  • the vacuum block is clamped by means of vacuum or mechanically on the fixing table or on the fixing beam, wherein the workpiece to be machined is in turn held by means of negative pressure on the block suction.
  • the vacuum blocks each have a sealing plate, which has on its circumference a voltage applied to the workpiece sealing lip.
  • Such sealing plates are e.g. known from DE 202 06 489 U1 and DE 202 06 490 U1.
  • the invention is therefore based on the object to provide a sealing plate, which is also applicable to vacuum blocks with Tastventilen.
  • sealing plate of the type mentioned in the present invention that it is provided with a membrane and the membrane allows air to flow through.
  • the sealing plate according to the invention has the significant advantage that it can be traversed by air and retained on the membrane processing residues.
  • the suction block can be equipped with Tastventilen so that it is detected whether a workpiece rests or not.
  • the feeler valve is opened, and when the vacuums are empty, the feeler valve remains closed. Vacuum blocks that are not occupied, so no longer have to be removed.
  • the membrane is located on the sensing valve, which is operated via the membrane.
  • the membrane has a smaller thickness than the sealing plate.
  • the thickness of the membrane is 90% to 50%, in particular 85% to 60%, preferably 80% to 70% less than the thickness of the sealing plate. In one embodiment, the thickness of the membrane is 30% of the thickness of the seal plate.
  • a preferred embodiment of the invention provides that the membrane has a joint at its edge.
  • This joint has a smaller thickness than the thickness of the membrane.
  • the joint is advantageous e.g. formed as a film hinge, wherein the film hinge may also have a waveform.
  • the membrane has openings, e.g. slit-shaped or round, in particular circular openings on.
  • the air is sucked through the openings and the membrane has the function of a filter.
  • the axis of the opening is orthogonal to the surface of the sealing plate.
  • the membrane is designed so elastic that it can be bulged out of the plane of the sealing plate when the plunger of the feeler valve rests against the underside thereof.
  • the touch valve is not hindered by the adjacent membrane.
  • the membrane is made of the same material as the rest of the sealing plate.
  • the membrane is almost cost neutral directly introduced into the suction plate.
  • the sealing plate consists of a two-component material, wherein the membrane is formed by the more elastic material. This has rubber-elastic properties and is preferably made of an elastomer.
  • the top of the diaphragm is flush with the top of the seal plate or the workpiece seating surface when the workpiece rests.
  • the plunger is thus shorter in the thickness of the membrane than conventional plungers.
  • the plunger may be mushroom-shaped at its upper side, so that the membrane is not damaged by the plunger, in particular pierced.
  • the upper side of the membrane is only partially provided with openings, wherein the sections or the areas lying between the sections are formed as information carriers.
  • the information can be hints for the use of the block vacuum or the sealing plate. You can, however, e.g. also a logo or the manufacturer included.
  • Figure 1 is a perspective view of a block suction with attached sealing plate according to the prior art
  • Figure 2 is a section II - II according to Figure 2 without attached workpiece;
  • FIG. 3 shows the section II - II according to Figure 2 with attached workpiece
  • Figure 4 is a perspective view of the block suction with attached sealing plate according to the invention.
  • FIG. 5 shows a section V - V according to FIG. 4 without a mounted workpiece
  • FIG. 6 shows the section V - V according to Figure 4 with attached workpiece
  • Figure 7 is an enlarged view of the section VII of Figure 4.
  • Figure 8 is an enlarged view of the membrane with a logo.
  • FIG. 1 shows a perspective view of a total of 10 designated block suction, which is placed on a fixing bar 12 only hinted. Against lateral slippage of the suction block 10 is held by aprons, not shown, whereas the suction block 10 in the direction of the double arrow 16 on the fixing bar 12 is displaceable.
  • the suction block 10 has on its suction side 18 on a sealing plate 20 which has a sealing lip 22 on its side facing the workpiece (not shown).
  • the sealing lip 22 defines a suction space 24, to which for holding the workpiece negative pressure is applied.
  • the sealing plate 20 has a central opening 32 which is penetrated by the plunger 30 of the Tastventils 28.
  • the sensing valve 28 serves to detect a resting on the sealing plate 20 workpiece. If, as shown in FIG. 2, there is no workpiece on the sealing plate 20, the sensing valve 28 closes and no air is sucked out of the suction space 24. When resting on the sealing plate 20 workpiece, as shown in Figure 3, the plunger 30 is pressed and the sensing valve 28 is opened. The air is sucked out of the suction space (as shown by the arrows 34) and thereby sucked the workpiece to the seal plate 20. With the suction of the air, however, dirt or dust can be sucked, which can cause problems in the sensing valve 28 or in subsequent components.
  • the sealing plate 20 has no opening for the plunger 30, but according to the invention is provided with a membrane 36.
  • this membrane 36 has a plurality of small openings 38, which are preferably arranged in an annular area around the center of the membrane 36.
  • the material and / or the thickness of the membrane 36 are chosen so that it is elastically deformable with little force.
  • the plunger 30 engages and pushes the membrane, as shown in Figure 5, on the defined by the support elements 26 support plane 40.
  • the membrane 36 is thus clearly visible. If a workpiece is placed on the sealing plate 20, then the plunger 30 is pressed together with the membrane 36 to the support plane 40, which is shown in Figure 6.
  • the air can, as shown by the arrows 34, flow from the suction chamber 24 through the membrane 36 into the sensing valve 28, wherein dirt is retained.
  • the membrane 36 is connected via a hinge 42 to the rest of the sealing plate 20, wherein the joint 42 is formed by a corrugated film hinge, which allows a spatial movement of the membrane 36. It can also be seen in FIGS. 5 and 6 that the tip of the plunger 30 is formed by a mushroom head 44 so that the membrane 36 is not damaged by the plunger 30.
  • the thickness d of the membrane 36 is only a fraction of the thickness D of the sealing plate 20, whereby the elasticity of the membrane 36 is substantially increased.
  • FIG 8 shows an enlarged view of the membrane 36, wherein the openings 38 are provided only in two sections 46. These sections 46 may have the shape of a logo.
  • the area 48 located between the sections 46 is formed as an information carrier 50 and carries information for the use of the device or e.g. the name of the manufacturer.
