Definitions

  • the invention relates to a clamping rail for a membrane of a membrane press.
  • the patent DE 10 2005 031416 B4 describes a membrane press with a device for tensioning the membrane with a support frame and with holding elements in which the membrane can be fixed without tools.
  • the retaining elements are formed like a claw with two clamping surfaces and a clamping bolt.
  • the holding elements are buckle-shaped in the manner of a belt buckle, a clamping lock, a spring clip or a sliding ridge lock. If the membrane is stretched in a plane, is deflected at edges and the clamping force acts perpendicular to said plane at the edges, must be held during the assembly of the membrane whose edge so long until the holding elements clamp the membrane sufficiently. This process is difficult to handle by a single person, not least because the retaining elements must be held when clamping the membrane.
  • the invention is based on the object to propose a tensioning rail with which the assembly and disassembly of the membrane is easier and faster than in the known from the prior art devices possible.
  • the clamping rail a support rail contains, in which at least one clamping bar is releasably received, wherein the clamping bar is formed for clamping at the edge of the membrane.
  • This solution according to the invention has the particular advantage that a newly inserted membrane can be equipped independently and outside the membrane press with clamping bars, which are then only mount in the mounting rail.
  • the mounting rail does not have to be dismantled, but remains on the membrane press all the time.
  • Another significant advantage of the tensioning rail according to the invention is that it can also be installed in existing membrane presses, for example as a replacement for an existing fastening device for the membrane.
  • the cross section of the mounting rail has the shape of a C.
  • a shape is simple and inexpensive to manufacture and allows in a particularly simple manner the mounting and unmounting of the clamping bar.
  • the C-shape of the mounting rail has a straight back region and a first leg directed parallel to the back region and a second leg directed parallel to the back region. This allows a convenient and space-saving arrangement of the mounting rail on a membrane press.
  • the clamping bar has a retaining strip in the form of a flat profile, which rests in the region of a first longitudinal edge on the inside of the first leg of the support rail and is seated with a present in the opposite longitudinal edge groove on the second leg of the support rail.
  • the clamping bar can be very easily hooked into the mounting rail by first the first longitudinal edge of the retaining strip is pushed behind the first leg of the support rail and then the second longitudinal edge is placed with the groove disposed therein on the second leg of the support rail.
  • the clamping bar can be easily moved in the support rail, if necessary, it is advantageous if a friction-reducing coating is present in the groove and / or on the second leg.
  • a terminal strip is provided which can be pressed against the retaining strip to clamp the membrane between the retaining strip and the terminal block.
  • at least one screw is present to press the retaining strip and the terminal strip against each other.
  • the means for local deflection and / or compression of the membrane at least one existing in the retaining strip and / or in the terminal strip, longitudinal recess, wherein in at least one of the recesses a profile is inserted.
  • the invention also relates to a membrane press for pressing components, comprising a lower part on which the components are to be placed and an upper part with a diaphragm, wherein the upper part and the lower part relative to each other from an open position for insertion and removal of the components in a closed position are movable, in which between the membrane and the lower part of a tightly closed, evacuated space is formed and wherein the upper part of a clamping device is arranged with a clamping drive for tensioning the membrane.
  • This object is achieved in that at least two independent clamping drives for clamping the membrane in the longitudinal direction and in the transverse direction are present.
  • This solution according to the invention has the advantage that the paths during clamping of the membrane in the longitudinal direction and transversely to each other are independently adjustable and thus can be uniformly set in all directions the tension in the membrane present in the membrane after tensioning in all directions.
  • the tensioning device has tension elements which connect the tensioning drives to the edges of the diaphragm. This allows the arrangement of the clamping drives at almost any point of the upper part.
  • clamping drives are arranged on top of the upper part and the tension elements are deflected by deflection. This arrangement saves space, while the clamping drives remain easily accessible.
  • the membrane press is equipped with slide rails according to one of claims 1 to 9.
  • Fig. 1 shows in a perspective view a section of an upper part 1 of a membrane press.
  • the upper part 1 is constructed in the manner of a downwardly open box and carries on its underside a membrane 2 made of a flexible, elastic material, such as silicone or a similar material.
  • the upper part 1 is adjustable by a lifting drive, not shown, with respect to a lower part of the membrane press, not shown.
  • the membrane 2 is intended to form a dense space in the lowered position of the upper part with the lower part, are received in the parts to be pressed.
  • In the lower part can also be present a heating plate for heating said parts. By evacuating the said space, the membrane exerts a pressure on the parts to be pressed.
  • the parts may be, for example, photovoltaic elements and glass plates containing laminates, which are laminated by means of the membrane press.
  • the upper part 1 is equipped with a tensioning device for the diaphragm 2.
  • the edges of the membrane 2 are deflected upwardly on each side of the usually rectangular shaped upper part 1 and the clamping device comprises at each edge of the membrane 2, a tensioning rail 3, whose structure will be described in more detail below.
  • Each tensioning rail is connected to at least one tension element 4, for example a rope, which is guided on the upper side of the upper part 1 via a deflection roller 5.
  • clamping drives 6 are arranged, which may be formed, for example, as a hydraulic or pneumatic piston-cylinder units or as spindle drives. Between the clamping drives 6 and the ropes 4 power transmission beams 7 may be provided.
  • each retaining element In the clamping devices known from the prior art, in which the membrane is connected by holding elements with a clamping frame, to disassemble the membrane each retaining element must be detached individually from the edge of the membrane before the membrane can be removed from the membrane press. The new membrane must then also be re-connected to each holding element, for which purpose in each case a portion of an edge of the membrane must be raised and inserted into the holding element. This work takes a relatively long time and is hard to manage by a single person.
  • Fig. 2 shows in one opposite Fig. 1
  • This includes a roughly C-shaped mounting rail 8 with a straight back portion 9 and two opposite, parallel to the back portion 9 legs 10 and 11.
  • the leg 10 is longer than the leg 11 and is arranged at a greater distance from the back region 9 than the leg 11.
  • a screw 12 is provided for fastening the tension element 4.
  • a clamping bar 13 is inserted such that it can be removed without the aid of tools.
  • the clamping bar 13 in turn includes a retaining strip 14 and a terminal block 15 which receive the membrane 2 between them.
  • a threaded bolt 16 is arranged, which allows using a nut, such as a cap nut 17 to clamp the terminal block 15 against the retaining strip 14.
  • the threaded bolt 16 may have a longitudinal slot and instead of the cap nut 17 may be provided a wedge, which is driven in this longitudinal slot.
  • means for clamping the membrane are conceivable that can be operated without the aid of tools, for example, wing nuts, knobs or rotary lever can be used instead of cap nuts or clamping mechanisms can be provided based on the principle of the bayonet or the eccentric ,
  • the retaining strip is provided with longitudinal recesses in which insertion profiles 18 are added.
  • the terminal block 15 has in the region of the insertion profiles 18 also longitudinal depressions, so that the membrane 2 is repeatedly bent during clamping, whereby the frictional force and thus the resistance to tearing increases significantly.
  • insertion profiles 18 and corresponding surveys can be provided directly to the retaining strip 14 or the respective areas of the retaining strip 14 and / or the terminal block 15 may be designed like a tooth.
  • a longitudinal groove 19 is attached, which is seated in the support rail 8 inserted clamping bar 13 on the leg 11 of the support rail 8.
  • the clamping bar 13 during the tensioning of the diaphragm 2 can optionally easily move along the support rail 8
  • the groove 19 and / or the relevant area of the leg 11 is preferably provided with a friction-reducing layer, for example with a film of polytetrafluoroethylene or a similar material.
  • a friction-reducing layer for example with a film of polytetrafluoroethylene or a similar material.
  • screw caps 20 are provided which are inserted into openings of the upper leg 10 of the support rail 8 and the lifting of the clamping bar 13 verunmony.
  • the screw caps 20 have a non-round end and also the openings are not round. If the screw caps are rotated by 90 °, for example, after insertion into the openings, they can not fall out of the openings.
  • the lifting of the clamping bar 13 can also be prevented by other means, for example by screws, bolts or a profile bar which is inserted above the retaining strip 14 in the support rail 8.
  • a membrane of a membrane press proceeds as follows. First, a new membrane 2 outside the machine is provided at its edges with clamping bars 13. The latter are preferably storable in different lengths and are attached as needed, that is, in particular depending on the material, the thickness and the surface of the membrane 2 at intervals or gapless at the edges of the membrane 2. During this preparatory step, the membrane press can still be operated. Then in the membrane press an optionally below the membrane 2 existing clamping and sealing frame is released and the clamping drives 6 are extended, such that the membrane 2 is loose. After the screw caps 20 have been removed in the support rails 8, can the membrane to be replaced 2 are posted by the clamped at their edges clamping bars 13 are extended from the mounting rail 8, similar to the sliding door of a showcase.
  • the upper part 1 is raised and the membrane 2 to be replaced is removed from the membrane press. Subsequently, the prepared new membrane 2 is inserted into the membrane press. The previously clamped to the new membrane 2 clamping strips 13 are inserted into the top of the support rail 8 and set with the groove 19 on the leg 11 of the support rail 8. After inserting the screw caps 20 in the support rail 8, the new membrane 2 can be tensioned by the clamping drives 6. Now, the upper part 1 can be placed on an optionally existing clamping and sealing frame and this hooked on the upper part 1. Then the membrane press is ready for production again.
  • the clamping device according to the invention has the further advantage that due to the independently present on the longitudinal side and on the broad side of the upper part clamping rails, the tension of the membrane can be constructed and adjusted independently of each other in both directions.
