Definitions

  • the invention relates to a cutting station for cutting one continuously colliding on one strand Sub-forms of the same length of conveyed belt plastically deformable material in individual moldings on the Ends of the lower molds, with at least one cutting device is attached to a reversibly movable carriage and through the lower molds during the cutting process Guide elements are guided.
  • Such a cutting station is used, for example, at Manufacture of concrete roof tiles using the extrusion process needed.
  • This method is based on a constant Speed promoted strand of abutting Subforms of equal length as a fresh concrete layer Endless tape applied through the top Forming tools of the usual for concrete roof tiles Surface contour is shaped accordingly.
  • This continuously applied fresh concrete layer then in a cutting station at the end of each each lower mold by means of a cutting device with a Knives cut so that each subform is a single one Molded body carries, here a concrete roof tile blank. Is to it is necessary that the knife is always exactly at the joint inserted between two sub-forms in the fresh concrete layer becomes.
  • the strand usually moves horizontally Direction and the knife in the vertical direction.
  • a cutting station of the type described is from the DE-A-22 52 047 known. With this cutting station it is from an air cylinder operated knife on an in horizontally reversible movable carriage mounted, the slide over a crank and Connecting rod is driven. The cutting device is on Screwed on slide, the guide elements are on the Screwed on cutting station. When changing the model produced concrete roof tiles must each Cutting device and the guide elements replaced and be readjusted. This requires a considerable changeover time required throughout the entire production facility stands still.
  • the object of the present invention is a cutting station of the kind described at the beginning the changeover for differently shaped fittings, especially for concrete roof tiles of different shapes, in short time is possible.
  • the object is achieved in that the Cutting device is mounted on an intermediate frame, the is attachable to the carriage, and that the guide elements an adapter are mounted on the cutting station is attachable.
  • This design enables the cutting device complete with all accessories with the intermediate frame replace and also those adjusted on the adapter Guide elements to be replaced completely with the adapter. This reduces the changeover time to a few Minutes reduced.
  • a Dressing device can be attached with a dressing tool. This is desirable, for example, around the foot Round off the top edge of a concrete roof tile.
  • the knife of the cutting device is usually used by one double-acting pneumatic cylinder driven so that Cut can be done particularly quickly.
  • the dressing tool moves pneumatically. To a Glue concrete to the knife or dressing tool prevent it, it is advantageous if these each in Rest position to be cleaned.
  • the guide elements are required to during the Cutting a dodging a subform or down to the side to prevent. Since the subforms on the Sliding along guide elements, it is advantageous if this at least one coated to reduce wear Have surface.
  • a layer of hard metal is applied to the guide elements or the guide elements can be as hard metal plates be trained.
  • Exact lateral guidance is achieved if at least Two side guide elements are provided, which as Guide rails can be formed and on each other lie opposite guide surfaces of the lower mold.
  • a particularly precise guidance of the lower molds during the Cutting process is achieved when at least one of the lateral guide elements transverse to the conveying direction of the Lower mold is slidable, so that this is due to its Cross movement small tolerances between individual sub-forms is able to compensate.
  • a constant manager is maintained if that Pneumatically displaceable second lateral guide element can be pressed against the lower mold.
  • a pneumatic cylinder can be a guide element, for example act. The pneumatic cylinder presses the second side Guide element on one of the side guide surfaces of the Lower mold on and thus the lower mold against that opposite first lateral guide element, which then forms the reference surface.
  • FIG. 1 shows a cutting station 10 according to the invention for Cutting one out continuously on one strand 14 forming abutting sub-molds 12 conveyor belt made of plastically deformable material in individual fittings at the ends of the subforms 12.
  • the Strand 14 of the cutting station 10 is horizontal Conveying direction 16 - from left to right in FIG. 1 - fed.
  • On the machine frame 18 of the cutting station 10 is a reversibly movable parallel to the conveying direction 16 Carriage 20 provided.
  • the carriage 20 is on the side of String 14 arranged and slidable in horizontal guides stored.
  • the drive is not shown here Carriage 20 at least for a short distance the same speed as the strand 14 movable.
  • the cutting process takes place within this distance.
  • At the Carriages 20 are two protruding from the strand 14 Cantilever arms 22, 24 are provided with T-slots on which a Intermediate frame 26 is attached with T-slot stones with a precise fit.
  • the intermediate frame 26 carries a cutting device 28 which as a cutting tool one of a double acting Compressed air cylinder 30 transversely to the conveying direction 16 in a vertical direction Has knife 32 movable in the direction. Furthermore is on Intermediate frame 26 a dressing device 34 attached has a dressing tool 36, which by a double-acting compressed air cylinder 38 also transverse to Delivery direction 16 is movable. All supply lines to the devices arranged on the intermediate frame, in particular to the cutting device 28 and Dressing device 34 are with a quick coupling 40 connected to the cutting station 10.
  • Fig. 2 shows the cutting station 10 of Fig. 1 in the End view seen in the direction of conveyance 16.
  • a counterpart 42 can be coupled, which with the Cutting station 10 is connected to the machine frame 18.
  • a support piece 48 connected, on which an adapter 46 is attached.
  • the shaped pieces 12 are guided on the top of the adapter 46.
  • Fig. 3 shows the adapter 46 in an enlarged view Cross-section.
  • the adapter 46 is the Adjusted top of the support piece 48.
  • the one shown here Adapter 46 is designed for sub-molds 12, which for Production of ridge or ridge stones are suitable.
  • On the upper side of the adapter 46 carries two horizontal guide elements 50 and 52, which act as thin plates are made of hard metal. From the inside the lower mold 12 in laterally by two as guide strips trained lateral guide elements 54 and 56, whose guide surfaces are coated with hard metal.
  • the first lateral guide element 54 is fixed to adapter 46 connected while the second side guide member 56 in Transverse direction to the strand 14 is horizontally displaceable.
  • the Transverse displacement of the second lateral guide element 56 takes place with constant force by means of a Pneumatic cylinder 58.
  • the manager is above that on the Pneumatic cylinder 58 acting air pressure adjustable.
  • Fig. 4 shows in cross section a second adapter 146 which the support piece 48 is mounted.
  • the second adapter 146 is trained for sub-molds 112, which for the production of Verge stones are suitable.
  • the second adapter 146 points a total of 3 horizontal guide elements 150, 151, 152, which are designed as hard metal plates.
  • the first lateral guide member 154 is on top of the Adapters 146 arranged while the second side Guide element 156 on a projection 158 of the Carrier piece 46 is attached.
