Definitions

  • the invention relates to a roof tile press with the in the preamble of Claim 1 specified features.
  • a roof tile press is from the DE 195 14 045 A1, from DE 43 44 636 C1 and from WO 96/32237 A1 known.
  • Roof tile press has several on a divided anvil side by side Subforms and on a common in the stand up and down movable Pressure piece an equal number of upper molds, which work with the lower molds.
  • On the other side of the stand is an unloading device attached which the roof tile blanks formed in the press from the lower mold extracts. The chunks are brought up on a first roller conveyor and the roof tile blanks conveyed on a second roller conveyor.
  • the loading device has guides on which a carriage with a suction lifting device runs, which picks up the slugs from the roller conveyor, into the open one Press between the upper molds and lower molds and the Put chunks in the lower molds.
  • the removal device has a similar structure.
  • the well-known roof tile press works with open forms. With open forms is worked with 20% to 50% excess material, depending on the type of roof tile. The excess material of the batz to be formed occurs laterally between the Upper form and the lower form, which is why the forms referred to as open forms become. Open forms are mainly used as a plaster cast forming roof tile. Due to the highly porous surface of the plaster and due to the water film that forms when the roof tile blank is formed the roof tile blank is sucked into the plaster mold from a chunk. In order to remove the roof tile blank, large release forces must therefore be of the order of 3000 to 5000 N can be overcome, many times over are higher than when working with closed forms. With one often used three-field press, in which three roof tile blanks in simultaneously three adjacent molds are pressed, the release forces are taken together three times as high.
  • closed molds are made from a cast steel alloy sprayed with kerosene as a release agent. It is also closed Steel molds are known to use ejectors for the roof tile blank, which with the frequently changing open plaster molds for cost reasons and because of the precise guidance of the ejector, which is hard to achieve in plaster molds have not been able to enforce so far.
  • the robot needs so much mass on its arm that it can be used for modern Roof tile presses become too slow and slow. In order to achieve the necessary working speed, one would have to have a robot use only approx. 800 N load capacity. However, this can be used for roof tile blanks do not detach from plaster molds. The situation becomes particularly difficult when one considers multi-field roof tile presses, e.g. a three-field roof tile press, because the robot will even have a load capacity of around 9,000 N to 15,000 N would.
  • roof tile presses with open forms have usually been used as turret presses or swivel beam presses, for example as in DE 43 44 636 C1.
  • the lower molds are located in a turret press on a hexagonal drum, which can be moved up and down step by step Thrust piece is moved through and an obliquely upwards pointing loading station on one side of the press stand and one unloading station on the other side of the press stand passes.
  • a swivel bar instead of a hexagonal drum, which is between a correspondingly obliquely upward Loading station and an obliquely upward unloading station and herschwenkt.
  • the loading device and the unloading device are in both Cases pivoted to move between the diagonally after Make the bottom mold pointing upwards and a horizontal conveyor belt can.
  • a roof tile press is known from CH 412 681, in which a roof tile blank is released from a lower mold by means of an unloading device by this sucks it to an abutment, which is similar to the roof tile blank Has contour. This will release the roof tile blank from the lower mold supported by an overpressure, which when pressing the roof tile blank is generated between this and the lower mold.
  • a suction lifter is known with which a concrete slab after setting by suction from a plastic mold can.
  • the present invention has for its object to show a way how to facilitate the removal of roof tile blanks from plaster molds can, so that this is accessible for handling by a robot, in particular also for roof presses with several fields.
  • the invention provides that for A separate drive removes the roof tile blanks from the lower molds is provided, which on the one hand can provide the high release force, which is a lot is higher than that for the subsequent transfer of the roof tile blanks is required, but on the other hand this high power is only available in a short way, because it's all about the roof tile blanks with the separate drive detach from the lower mold. Therefore, the dedicated one Drive, although powerful, is relatively small and light be so that it does not make the unloading device undesirably sluggish.
  • the invention thus creates the prerequisite for this as an unloading device a versatile and sufficiently fast hand-held
  • articulated arm robots with the usual drives of an articulated arm only the roof tile blanks detached from the lower molds on a conveyor, e.g. B. must be transferred to a roller or belt conveyor and the one on top of his articulated arm due to the extra on releasing specialized drive, not too heavily loaded because of this arranged drive only needs a short stroke and therefore small and can be easily formed.
  • the usual drives for moving the articulated arm do not have to provide the transfer force, but only a transport task have, they can also be designed slightly, so that the inertia the robot can be kept relatively low.
  • the invention is suitable for different roof tile presses, for anvil presses, for turret presses, also for swivel beam presses, the use of an articulated arm robot because of its versatility and mobility is particularly advantageous for turret presses.
  • the unloading device expediently has lifting devices that operate with suction on, e.g. one equipped with air intake openings or suction cups, from a knife box for trimming the edges of the roof tile blank equipped suction plate, which can be lifted and lowered on a carrier is.
  • This carrier can be a plate which is at the top an articulated arm of a robot is attached.
  • a lifting device working with suction is particularly suitable for an anvil press, which is attached to a sled, which on guides is movable, directly or indirectly on the stand of the roof tile press are attached.
  • the lifting device can be moved from this carriage to the one in the Roof tile blank lying below the mold, suck it out loosen the form, lift it up a short distance, then slide it lengthways the guides move up to a conveyor and put it down there again.
  • the lifting device is preferably by one or more pressure medium cylinders actuated, in particular by hydraulic cylinders, because these are compact Dimensions and low weight allow high forces in short strokes. It but it is also possible to use electromechanical drives to the roof tile blanks can be removed from its lower mold with a short stroke, e.g. electromotive driven spindles, cams, eccentrics, toggle levers and the like for the transmission of high forces during short strokes suitable gear elements.
  • Toggle lever drives generate close to the according to the toggle lever characteristics Extended position of the toggle lever high forces with low strokes. You can do that by taking advantage of that by lifting the device and its carrier connects one or two pairs of toggle levers and one at the knee joint Pressure cylinder connects.
  • Another option is power cylinders to use, which work according to the wedge lever principle and depending on the design overcome a large stroke (the attack stroke) in a short time and in a previous one or subsequent power stroke a much higher force than a conventional pressure medium cylinder with the same piston diameter within one can transmit short distance.
  • the power cylinder is preferred pneumatically operated, but could also be driven hydraulically or by a spindle his. For lifting, transferring and depositing the roof tile blank only a low suction power is required, which depends on the weight of the roof tile blank is determined.
  • An embodiment of the invention is particularly preferred in which the peeling force is applied in that the effecting the stroke of the lifting device separate drive elements not between the lifting device and their carrier, but between the lifting device and the carrier of the lower molds are effective so that the lifting device is pushed away from the lower molds becomes.
  • the easiest way to do this is to use the lifting device, e.g. on the suction plate for the roof tile blanks, several short-stroke pressure medium cylinders are provided, preferably at the four outer corners the lifting device one each, the piston rods against the carrier of the sub-molds are directed and pressed against it in order to detach it cause.
