Definitions

  • Cutting station for cutting a continuously conveyed band of plastically deformable material into individual shaped pieces
  • the invention relates to a cutting station for cutting a band of plastically deformable material, which is continuously conveyed on a strand and abutted against one another, of the same length into individual shaped pieces at the ends of the lower molds, at least one cutting device being attached to a reversibly movable carriage, and the lower molds during the cutting process Guide elements are guided.
  • Such a cutting station is required, for example, in the production of concrete roof tiles using the extrusion process.
  • a fresh concrete layer is applied as an endless band on a strand of mutually abutting lower molds of the same length, which is conveyed at a constant speed, and which is shaped on the top by means of molding tools corresponding to the surface contour customary for concrete roof tiles.
  • This continuously applied fresh concrete layer is then cut in a cutting station at the end of each lower mold by means of a cutting device with a knife, so that each lower mold carries a single molded body, here a concrete roof blank.
  • the knife is always inserted exactly into the fresh concrete layer at the joint between two sub-molds.
  • the strand moves in the horizontal direction and the knife in the vertical direction.
  • a cutting station of the type described at the outset is known from DE-C 22 52 047.
  • the knife which is actuated by a compressed air cylinder, is mounted on a slide which is reversibly movable in the horizontal direction Connecting rod is driven.
  • the cutting device is screwed onto the slide, the guide elements are screwed onto the cutting station.
  • the cutting device and the guide elements must be replaced and readjusted. This requires a considerable changeover time during which the entire production plant is at a standstill.
  • the object is achieved in that the cutting device is mounted on an intermediate frame which can be attached to the slide, and in that the guide elements are mounted on an adapter which can be attached to the cutting station.
  • This design makes it possible to completely replace the cutting device with all accessories with the intermediate frame and also to completely replace the guide elements adjusted on the adapter with the adapter.
  • Fitting elements can be positioned. In this way it is achieved that the replaced intermediate frame is used immediately in the correct position for the slide and only needs to be attached to it.
  • the adapter can be positioned at the cutting station using fitting elements.
  • a dressing device with a dressing tool can be attached to the slide. This is desirable, for example, to round off the top edge of a concrete roof tile on the foot side.
  • the knife of the cutting device is usually driven by a double-acting compressed air cylinder so that the cut can be made particularly quickly. If available, the dressing tool is also moved pneumatically. In order to prevent concrete from sticking to the knife or dressing tool, it is advantageous if it is cleaned in the rest position.
  • the guide elements are required to prevent a lower mold from moving downwards or to the side during the cutting process. Since the subforms on the
  • Slide guide elements along it is advantageous if they have at least one wear-reducing coated surface.
  • a layer of hard metal can be applied to the surface of the guide elements or the guide elements can be designed as hard metal plates.
  • Exact lateral guidance is achieved if at least two lateral guide elements are provided, which can be designed as guide strips and rest on mutually opposite guide surfaces of the lower mold.
  • a particularly exact guidance of the lower molds during the cutting process is achieved if at least one of the lateral guide elements can be displaced transversely to the conveying direction of the lower mold, so that this can compensate for small tolerances between individual lower molds due to its transverse movement.
  • a constant guide force is maintained if the second side guide element, which can be moved laterally, can be pressed pneumatically against the lower mold.
  • a pneumatic cylinder for example, can act on the second lateral guide element. The pneumatic cylinder presses the second lateral guide element against one of the lateral guide surfaces of the lower mold and thus the lower mold against the opposite first lateral guide element, which then forms the reference surface.
  • Fig. 1 a cutting station according to the invention in the
  • FIG. 2 shows the cutting station from FIG. 1 in an end view in an adapter for lower molds
  • Fig. 3 shows the adapter of Fig. 2 in an enlarged view of the front view
  • Fig. 4 shows a second adapter in the front view.
  • FIG. 1 shows a cutting station 10 according to the invention for cutting a strip of plastically deformable material, which is continuously conveyed on a strand 14 formed from abutting sub-molds 12, into individual shaped pieces at the ends of the sub-molds 12 Strand 14 is fed to the cutting station 10 in the horizontal conveying direction 16 - from left to right in FIG. 1.
  • a carriage 20 which is reversibly movable parallel to the conveying direction 16 is provided on the machine frame 18 of the cutting station 10.
  • the carriage 20 is on the side of
  • the intermediate frame 26 carries a cutting device 28 which, as a cutting tool, has a knife 32 which can be moved vertically by a double-acting compressed air cylinder 30 transversely to the conveying direction 16. Furthermore, a dressing device 34 is attached to the intermediate frame 26, which has a dressing tool 36 which can also be moved transversely to the conveying direction 16 by a double-acting compressed air cylinder 38. All supply lines to the devices arranged on the intermediate frame, in particular to the cutting device 28 and the dressing device 34, are connected to the cutting station 10 via a quick coupling 40.
  • FIG. 2 shows the cutting station 10 from FIG. 1 seen in the end view in the conveying direction 16.
  • the quick coupling 40 is shown in a side view, which can be coupled to a counterpart 42, which is connected to the cutting station 10 on its machine frame 18.
  • a carrier piece 48, on which an adapter 46 is fastened, is also connected to the machine frame 18.
  • the shaped pieces 12 are guided on the upper side of the adapter 46.
  • Fig. 3 shows the adapter 46 in an enlarged representation in cross section.
  • the adapter 46 is the Adjusted top of the support piece 48.
  • the adapter 46 shown here is designed for lower molds 12 which are suitable for the production of ridge or ridge stones.
  • the adapter 46 laterally carries two horizontal guide elements 50 and 52, which are designed as thin plates made of hard metal. From the inside, the lower mold 12 is guided laterally through two lateral guide elements 54 and 56 designed as guide strips, the guide surfaces of which are coated with hard metal.
  • the first lateral guide element 54 is firmly connected to the adapter, while the second lateral guide element 56 is horizontally displaceable in the transverse direction to the strand 14.
  • the transverse displacement of the second lateral guide element 56 takes place with constant force by means of a pneumatic cylinder 58.
  • the guide force can be adjusted via the air pressure acting on the pneumatic cylinder 58.
  • FIG. 4 shows in cross section a second adapter 146, which is mounted on the carrier piece 48.
  • the second adapter 146 is designed for sub-molds 112 which are used to produce
  • Verge stones are suitable.
  • the second adapter 146 has a total of 3 horizontal guide elements 150, 151, 152, which are designed as hard metal plates.
  • the first lateral guide element 154 is arranged on the top of the adapter 146, while the second lateral guide element 156 is fastened to a projection 158 of the carrier piece 46.
  • first adapter 46 Concrete roof tiles or on first subforms 12 for the production of ridge or ridge stones, only the adapter 146 is exchanged for another one, for example a first adapter 46. It goes without saying that when using the cutting station 10 with the first adapter 46, the second lateral guide element 156 can remain on the carrier piece 48. The required replacement of the adapter 146 with the adapter 46 can be done within a very short time when converting Changeover time. Likewise, the intermediate frame 28 can be quickly replaced by another intermediate frame on which the cutting device 28 required for the other Dachstein model and, if necessary, a dressing device 34 are mounted in an exactly adjusted manner.
