Definitions

  • the present invention relates to a discharge device for discharging adhesive to a substrate surface having at least two adhesive cylinders for receiving filled with adhesive bags or cartridges having at their front end outlet openings, wherein in each of the adhesive cylinder, a punch is arranged axially movable to the in To press the bags or cartridges adhesive from the outlet openings of the adhesive cylinder, and are attached to the punches push tubes which protrude axially at their free end portions of the rear end of the adhesive cylinder and are connected to each other via a connecting element, and with an actuator which with the push tubes is coupled via the connecting element to adjust these axially.
  • Such discharge devices are already well known from the prior art and are used to apply adhesive, for example, before laying parquet or planks on a substrate surface.
  • a concrete embodiment of such a discharge device is for example in the EP 1 439 009 A1 described.
  • This discharge device has two adhesive cylinders for receiving filled with adhesive Bags on.
  • a punch is arranged axially movable to press the adhesive located in the bags from outlet openings of the adhesive cylinder.
  • the punches are connected to each other via a retaining plate, which projects through slots in the cylinder side walls in the two adhesive cylinder.
  • a threaded rod is arranged, which engages with a centrally fixed to the retaining element nut.
  • the threaded rod is rotated via a drive unit coupled to the threaded rod.
  • the rotational movement of the threaded rod is converted via the nut in a translational movement of the retaining element, whereby the stamp are axially adjusted in the adhesive cylinders.
  • the bags filled with adhesive inserted into the adhesive cylinders can be pushed outwards through the slots on the side walls during the axial adjustment of the punches. During operation of the discharge device, this can lead to the bags being torn or not completely emptied.
  • a discharge device of the type mentioned is from the US 4,913,553 known.
  • This discharge device has four adhesive cylinders.
  • a torque tube At whose in the adhesive cylinder facing ends in each case a punch is held in order to press the adhesive from the outlet openings of the adhesive cylinder.
  • a punch At the projecting from the adhesive cylinders other ends of the push tubes they are connected to each other via a plate.
  • a threaded rod is arranged on the plate, which engages in a threaded sleeve and is manually rotatable via a crank in order to adjust the coupled thrust tubes axially.
  • the present invention provides a discharge device, wherein the actuator comprises an electric drive unit having a drive pinion and a rack coupled to the drive pinion connected at one end to the connecting element and at its other end in a central receiving space between the adhesive cylinders is axially movable, wherein the drive pinion between the rear end face of the adhesive cylinder and the connecting element is in engagement with the rack.
  • the drive pinion can be decoupled from the rack in a simple manner, since the teeth of the rack are formed only along one flank. Furthermore, the point of engagement between the rack and the drive pinion may be above the adhesive cylinder. In contrast to a threaded rod drive in which the threaded rod between the adhesive cylinders is engaged with a nut, the adhesive cylinders can be arranged by the displacement of the engagement point between the rear end face of the adhesive cylinder and the connecting element comparatively close to each other. Moreover, the embodiment of the invention has the advantage that the rack is decoupled from the punches and no pressure but only tensile forces is exposed. This allows the rack to be designed comparatively weak.
  • a dispensing device which is easy to handle and allows easy replacement of adhesive-filled bags or cartridges. It is advantageous that pipe lengths of more than 600 mm can be realized by the inventive design, so that, for example, with a discharge device, which has two adhesive cylinders, each with a capacity of about 1.8 to 2 liters, adhesive to an area of about 7 m 2 up to 8 m 2 can be applied without having to refill the bags or the cartridges with adhesive in between.
  • the adhesive cylinders are interconnected so that the adhesive cylinders form a stable structural unit.
  • the adhesive cylinders can be connected to one another via spacers, which point to the adhesive cylinders to the Face surfaces are in contact with the adhesive cylinders, at least the rear spacer has a bore which is penetrated by the rack.
  • the spacers can be adhesively bonded to the adhesive cylinders, in particular adhesively bonded or welded.
  • two spacers are provided, through which the adhesive cylinder connected to each other at its front and rear end.
  • the connection is sufficiently stable in the typically used lengths of the adhesive cylinders by a spacer attached to the rear end region and to the front end region.
  • the receiving space for the rack is formed in a receiving tube, which is held between the spacers and in particular protrudes into the holes of the spacer or this passes through. This prevents a user of the discharge device can injure in operation on the axially displaceable rack.
  • a cover plate which engages over the adhesive cylinder at its rear end face, wherein the cover plate has through openings, which are penetrated by the push tubes and the rack. Through the cover plate, the push tubes and the rack on be easily aligned with the adhesive cylinders and the receiving space.
  • the push tubes can be mounted radially in the through holes of the cover plate via plain bearings. As a result, a radial emigration of the push tubes is prevented, in particular when the adhesive-filled bags or cartridges are compressed.
  • the cover plate can come into contact with the rear-mounted spacer and be releasably secured thereto.
  • the cover plate can be clamped by quick-release fasteners axially against the rear spacer.
  • the drive unit is held on the cover plate.
  • the drive unit can be fastened together with the cover plate in a simple manner to the adhesive cylinders.

  • a particularly light and in series production well producible discharge can be achieved, that the adhesive cylinder and a receiving tube, in which the receiving space for the rack formed and which is arranged between the adhesive cylinders are made of an extruded plastic profile.
  • This allows a particularly compact design of the discharge since the adhesive cylinder and the receiving tube form an extrusion without having to be connected by spacers.
  • this can parallel to the receiving tube extending receiving pockets, in which flat profiles can be used, for example, aluminum, to which rivets or screws of the quick-release fasteners are attached.
  • the adhesive cylinders have a diameter of about 30 mm to about 100 mm, preferably about 63 mm and the receiving space has a diameter of about 10 mm to about 30 mm, preferably about 15 mm.
  • the preferred diameter of the adhesive cylinders running of the adhesive in the bags has been reduced.
  • a rack with a diameter of about 10 mm is sufficiently stable, since it is charged only to train.
  • the drive unit is preferably switchable between an operating position in which the rack is axially adjustable via the drive unit, and a filling position in which a free axial movement of the rack within the drive unit is possible. Due to the free axial movement of the toothed rack in the filling position, these and thus also the punches can be particularly fast be brought into a starting position in which a filling of the adhesive cylinder is possible.

  • an axial bore 4 is provided in each case, into which a receiving tube 5 held between the spacers 2a, 2b engages.
  • a respective punch 6 is arranged axially movable to push the adhesive located in the bags through outlet openings 7 on the front end face 8 of the adhesive cylinder 1.
  • push tubes 9 are attached to their free End regions 10 project axially from the rear end face 11 of the adhesive cylinder 1 and are connected to one another via a connecting plate 12.
  • a rack 13 is arranged, which is connected at its one end to the connecting plate 12 and engages at its other end in the receiving tube 5.
  • a cover plate 14 which engages over the adhesive cylinder 1 at its open rear end face 11.
