Definitions

  • the invention relates to a tile scissors for cutting Tile blanks, with a support table for the tile, one upper and lower scissor knives and one output side table for receiving the separated Tile pieces.
  • Tile scissors of this type are known. They are used when the density distribution in a tile blank can be determined should. For this, the tile scissors are used pressed tile blank for example by three cuts each Longitudinally and transversely in sixteen equally large samples divided. The so-called “Apparent density” determines, on the one hand, the weight of everyone Sample and secondly by immersing the samples in mercury or by another method the volume is determined and from the apparent density is calculated from these two measured values. The values of the apparent density over the surface determined in this way of the green tile serve, if necessary Degree of filling in the individual areas of the mold or Correct the press pressure of the press accordingly.
  • the invention has for its object a tile scissors to develop a flexible knife that as such is easy to use Construction and manufacture is.
  • this object is achieved in that at least one of the two scissors knives of a tile scissors from a sheet clamped along one side resilient material is made and that the sheet along the cutting edge by cuts starting from the cutting edge is divided like a comb into cutting segments shaped in this way are that when you put the knife on the Tile surface independently of one another in the knife level yield resiliently and with their cutting edges Adjust the relief of the surface.
  • the flexible scissor knife according to the invention provides one extremely simple construction and can be compared to the known constructions with relatively little Create effort.
  • the starting from the cutting edge Cuts can be made with a suitable laser, for example be attached.
  • the scissor knife according to the invention has furthermore the advantage that the cutting segments are arbitrary can be made narrow, so that the cutting edge of this Scissors knife also small-scale structures of the Can customize tile surface. When lowering the Scissors knife the cutting process takes place under even Loading of all cutting segments.
  • the resilient elasticity of the Cutting segments achieved by moving them out of their plane have bent areas. So the cutting segments for example an S-shaped curved section or one have approximately bent at right angles, the Blocking of the cutting segments in that of the cutting edge neighboring area.
  • a tile scissors with an upper and a lower one Scissors knife can also be characterized by the fact that lower scissor knife from a rigid, below the plane of the Support table fixed knife, and that the Support table so pivotable about a horizontal axis of rotation is stored so that when the upper knife is put on lowers the tile.
  • the table is expediently carried through in the unloaded state a mechanical spring or by a hydraulic or pneumatic cylinder, as well as an adjustable stop in held in its horizontal position.
  • a lowerable stop bar can be provided for Determination of the position of the tile during the cutting process.
  • the tile scissors have one Provide sliding device with which the cut Strips or samples pushed onto the exit table become.
  • the slide consists of a comb-like arrangement Bars penetrating openings in the lower knife.
  • tile scissors immediately in front of and / or behind the area of the scissor knives in one or more hinged flaps at the level of the table provided, by their pivoting unusable Tile remnants can be removed from the tables.
  • Tile scissors include, as shown for example in Fig.5 one can see a mounting frame 1, 2, a support table 3 for the tile blank 4 to be cut, a table top 5 for Picking up the separated pieces of tile, a lower one Scissor knife 6 and an upper scissor knife 7.
  • a lowerable Stop bar 8 ensures that strips are always the same width of the tile blank can be cut.
  • At least one of the two scissor knives 6, 7 has an elastically flexible Cutting edge and is suitable for cutting tiles with a structured, relief-like surface. It has that Structure according to the invention, as it is for example in Figures 1 to 4 is shown.
  • the scissor knife with the resilient cutting edge consists of a one-piece sheet of spring steel sheet, whose elasticity is essentially perpendicular to the Cutting edges running incisions and through angled Sections is reached.
  • Knife blade 9 in the upper area in a knife holder 10 clamped.
  • Knife blade By perpendicular to the cutting edge 11 in constant spacing cuts 12 is that Knife blade divided into cutting segments 13.
  • the Cutting segments 13 are inherently over in their lower region the entire knife blade extending guide strips 14 in their Level kept and led. Between these guide strips 14 and the knife holder 10, the cutting segments 13 are S-shaped bent and thereby achieve their elasticity so that they become to the irregular surface of the tile to be cut can create sensitive.
  • the guide strips 14 serve as Blocking strips by using a not shown Device to be pressed against the cutting segments and these clamp between them. By lowering the knife further the cutting process is then carried out.
  • the knife blade 15 shown in FIGS. 2 to 4 represents the simplest embodiment of a Knife blade according to the invention.
  • the cutting segments 16 have an area 17 bent approximately at right angles.
  • the Knife blade is along the edge area 18 in a knife holder 19 firmly clamped.
  • the knife blade achieves its elasticity in that the areas 17 of the cutting segments when touching the tile surface to be bent upwards, as in the Fig.3 is shown. After all cutting segments are aligned with the Have created surface of the tile 20, the Guide bars 14 pressed against each other and block this way the cutting segments in this position.
  • the cutting segments can also be blocked in this way done as shown in Fig.4.
  • the knife holder 22 above each cutting segment 16 each provided with a guide groove 23 in which a slider 24 is slidably disposed.
  • the sliders 24 each rest the horizontally bent area of the associated Cutting segments and 16 together with the cutting segments raised. If the cutting segments 16 when lowering the Scissor knife have reached their end position is indicated by a Not shown device, the brake bar 25 against the Sliders 24 pressed. The sliders 24 are thereby in fixed their position so that another yielding to the Cutting segments is prevented.
  • the lower scissor knife can be a common rigid knife.
  • the upper one Scissor knife and the lower scissor knife one Gear arrangement provided through which the lower scissor knife is raised to a few millimeters above the table level, when the upper scissor knife lowers. This will make everyone Bending load on the tile when cutting, and thus a uncontrolled breaking of the tile avoided.
  • Fig. 5 shows a tile scissors in which the load is also applied the tile is avoided due to bending stress during cutting without, however, a movement coupling of the two Scissor knife is required.
  • the lower scissor knife 6 is in this case fixed as a rigid knife below the table level arranged, and at such a height that the Knife edge a few millimeters below the level of the Support table 3 lies.
  • the support table 3 is about the axis of rotation 27 pivoted. It is by the spring 28 or by a hydraulic or pneumatic cylinder in its kept horizontal position, with the horizontal rest position can be adjusted by the eccentric stop 29.
  • the Support table 3 pivoted about the axis of rotation 27, and the tile 4th descends until it reaches the cutting edge of the bottom Scissors knife 6 touches.
  • Fig. 7 shows a further development of the Tile scissors that consists of the cut off Strips or samples on the exit side of the scissors are automatically pushed out of the cutting area.
  • the table top 5 on the output side of the tile scissors arranged lower than the support table 3.
  • the support table 3 is a horizontally movable slide 36 arranged, for example by a pneumatic or hydraulic cylinder 37 is actuated.
  • Conveniently, consists of the slider 36 made of comb-like bars that corresponding breakthroughs in the fixed lower Pierce scissors knife 6.
  • the stop bar 8 to below the level of the table top 5 from.
  • the slide 36 advances, pushes the cut Samples on the table top 5 and moves to its starting position back.
  • the stop bar 8 is raised again, and the Tile scissors are ready for the next cutting process.
