Definitions

  • the invention relates to a device for positioning two plates against one another in such a way that two mutually facing end faces of the plates lie against one another at least almost without joints, in order to connect the plates permanently, in particular releasably, by means of connecting means, with at least two suction gripping elements, one of which is attached to one Plate is attachable and firmly suckable and the other is attachable and firmly suckable to the other plate, and with a device for pulling the end faces of the plates together.
  • connection means can basically be understood to mean any connection means, for example glue, screws or other mechanical connection means, which then hold the plates together permanently, although in particular releasably, after the positioning device has been released.
  • a device of the type mentioned above comprises two suction gripping elements in the form of suction plates, which are sucked against a respective top of the plate by means of a clamping lever.
  • the two suction gripping elements each have a metallic profile body and are above guide rods and one Connected threaded spindle which is rotatably mounted in one profile body and engages in a thread in the other.
  • the suction gripping elements and the plates sucked onto them can be pulled together by means of the threaded spindle.
  • the object of the present invention is to improve a device of the type mentioned at the outset such that an exact alignment of the plate surfaces in one plane is also possible.
  • suction gripping elements are arranged on a holding frame and in that the holding frame defines an abutment plane for the two plates, against which the plates can be placed by suction through the suction gripping elements.
  • a holding frame which defines a contact plane against a plurality of points, preferably via linearly extending contact strips, against which the plates are placed by means of the suction gripping elements, the plates are precisely aligned and positioned in a single plane and thus a flush transition between the surfaces of the two plates can be reached safely.
  • the suction gripping elements communicate with a vacuum generating device, so that the suction is not effected by manual actuation of tensioning levers or the like, but by means of a motor driven device and preferably driven by electric batteries.
  • any vacuum-generating device for example also an ejector device operated by compressed air, should be suitable.
  • the vacuum-generating device can be driven via electrical accumulators, that is to say, for example, it is formed by a vacuum pump operated by a rechargeable battery.
  • the negative pressure generating device and possibly the accumulators form part of the device and can be handled together with it.
  • the vacuum generating device is preferably mounted on the holding frame of the positioning device. It also proves to be advantageous if the batteries comprise battery packs that are detachable and exchangeable from the device and / or have a connection for a charging cable of a charger that can be connected to the fixed electrical network and can be recharged in this way.
  • the suction gripping elements are arranged on the holding frame such that they can be moved, at least in the mounting direction, that is to say essentially perpendicular to the contact plane. This makes it possible to first place the holding frame with the contact plane on the tops of the plates to be sucked in and then to place the suction gripping elements on the tops of the plates.
  • an embodiment is preferred in which the suction gripping elements protrude beyond the contact plane of the holding frame before the plates are sucked in. If the positioning device is then lowered or placed on the top of the two plates, the suction gripping elements first come into contact with the tops of the plates. If above from one Projecting above the contact plane of the holding frame, this means that the suction gripping elements with flexible suction plates or suction cups or conical sections of the suction gripping elements protrude above the contact plane and are then placed on the top of the plates with these areas. When the plates are sucked in, i.e.
  • the device mentioned at the beginning for pulling the end faces against one another could in principle be realized by any means which moves the suction gripping elements on the holding frame towards one another at least slightly.
  • Spindle drives which can be driven by an electric motor or, in accordance with a further embodiment of the invention, a piston / cylinder arrangement which can be driven pneumatically in particular could be used for this.
  • the pulling together of the end faces of the plates is achieved according to one embodiment of the invention by the movable arrangement of the suction gripping elements relative to the holding frame.
  • the movement of the suction gripping elements relative to the holding frame can be controlled by pressurizing the suction gripping elements, that is to say by the process of suctioning the plates.

  • At least one of the suction gripping elements is arranged in a positively guided manner on the holding frame such that, after the plates have been sucked in against the contact plane, this suction gripping element together with the suctioned plate can be moved toward the other, so that the mutually facing end faces of the sucked plates are movable against each other or pulled against each other.
  • At least one of the suction gripping elements can be pivoted with respect to the holding frame about an axis running parallel to the contact plane, wherein a multi-articulated arrangement of articulated arms can be used with respect to the pivotable arrangement.
  • the movement of the suction gripping elements towards one another can be achieved in that after the suction gripping elements on the top of the plates have been sucked in, a suction gripping element is sucked even closer to the plate positioned on the contact plane and thereby also performs a movement in the plant level. If a suction gripping element is placed with its edge of the suction plate on an upper side of the plate and the space between the suction gripping element and the upper side of the plate is evacuated, the plate is sucked against the suction gripping element and placed against the contact plane of the holding frame. This can also result in a movement of the suction gripping elements in the mounting direction relative to the holding frame.
  • the respective suction gripper element will move closer to the top of the plate.
  • it can at the same time perform a movement in the contact plane relative to the holding frame and can thus be moved together with the suctioned plate towards the further suction gripping element.

  • the positive guidance of the suction gripping elements with respect to the holding frame is preferably such that the plates are first placed on the contact plane and only then is a movement of the suction gripping elements together with the plates in the contact plane, the plates sliding against the holding frame against it.
  • At least one of the suction gripping elements is connected to the holding frame via two articulation points, an articulation point being displaceable in an elongated hole in an articulated rod.
  • This at least one suction gripping element or preferably also both suction gripping elements can be connected to the holding frame via a flat, closed rotary / push joint arrangement.
  • this rotary / push joint arrangement is articulated on the holding frame via a single articulation point and preferably holds a toggle lever which is preferably articulated in the area of its angling via the one articulation point on the holding frame.
  • the holding frame forms a frame surrounding the arrangement of the suction gripping elements.
  • the frame then preferably has essentially guader or box-like shape.

If the plate tops 8, 10 abut against the underside 36 of the holding frame 30, this underside 36 defines an abutment plane 62 for the plate tops 8, 10. This situation is shown in FIG. A separating joint 64 can be seen between the plates 4 and 6, which was already present before the positioning device 2 was placed on the plate tops 8, 10.
