Definitions

  • the invention relates to a method and a device, which are designed according to the preambles of claims 1 and 11 and are provided for the production of surface patterns having blanks for clinker bricks, bricks and the like.
  • emboss the corresponding surface pattern into the upper strand surface by means of a pressurized embossing roller that rolls on the raw material strand, the peripheral surface of which is provided with the negative pattern.
  • the relatively small diameter of the embossing roller prevents a uniform impression of the surface pattern.
  • Another disadvantage of the embossing rollers is that complicated surface patterns, particularly those with depressions that run obliquely or transversely to the direction of transport of the raw material strand, cannot be impressed without errors, since very often an offset between the negative pattern on the embossing roller and caused, for example, by fluctuating consistency of the raw material whose impression occurs on the strand surface.
  • Such an offset affects both the quality of surface patterns, which are self-contained, each assigned to a blank, and that of surface patterns, which are distributed over several blanks, are intended to produce an overall pattern by joining them together. If an offset occurs, the first-mentioned surface patterns can be arranged on two blanks in different ways, while in the last-mentioned surface patterns the joining together of the corresponding blanks does not match the overall pattern provided results.
  • the negative pattern is formed on an embossing stamp instead of on an embossing roller, it can be guided by appropriate guidance of the embossing stamp or of the raw material strand, at least during the actual embossing, when it is in engagement with the strand surface and pressed into or pulled out of it in a relative movement will be held immobile in its plane relative to the strand surface.
  • the negative pattern only performs the necessary relative movements relative to the strand surface perpendicular to it during the actual stamping. Cross movements of the negative pattern relative to the strand surface are excluded during the actual memorization.
  • the invention makes it possible in this way to impress even complex surface patterns of any configuration cleanly and in full accordance with the negative pattern. Offset and different impression depths do not occur.
  • the raw material strand can be cut into blanks at the intended locations without the self-contained surface pattern, each associated with a blank, being interrupted or the production of an overall pattern composed of surface patterns of several blanks being impaired.
  • the stamp is an upper stamp with which the surface pattern is embossed into the upper strand surface.
  • the surface pattern can also be embossed in the lower strand surface or in lateral strand surfaces with a correspondingly arranged embossing stamp and corresponding supports.
  • the surface pattern is embossed into strand sections separated from the raw material strand. This eliminates surface pattern distortions caused by stress relaxation, i.e. Changes in length and width in the area of the separation points prevented.
  • the surface pattern is imprinted with the speed of the extruded strand of raw material moving embossing stamp is possible, preferably according to the features of claims 5 and 15, a stationary embossing device is used for embossing the surface pattern in strand sections brought to a standstill. This simplifies the method and device and ensures a clean and identical impression of the negative pattern.
  • the support plate and the stop also serve to ensure a clean and identical impression of the negative pattern according to the features of claims 6 to 9 and 16 to 19.
  • claims 10 and 20 and 21 serve to ensure an embossing position of the strand section located in the embossing device that is as precise as possible by assigning the stop to one of the long sides of the strand sections.
  • the device according to the invention comprises an extruder 1, a transport device 2 with a cross conveyor 3, a separating device 4, a stationary embossing device 5 and a cutting device 6.
  • the extruder 1 is designed in a known manner and is used to extrude a strand of raw material 7.
  • the transport device 2 and the cross conveyor 3 are provided for supporting and transporting the raw material strand 7 from the extruder 1 beyond the cutting device 6.
  • the transport device 2 consists of three transport lines 8, 9, 10 running in the strand or extrusion direction.
  • the transport routes 8 and 9 each include a conveyor belt 11 which is supported by support rollers and driven by drive rollers.
  • the transport path 10 comprises five conveyor belts which are arranged at a mutual spacing and are supported and driven in the manner described above, which are also designated by the reference number 11.
  • the separating device 4 is arranged between the transport lines 8 and 9 and serves to separate the raw material strand 7 into individual strand sections 12.
  • the separating device 4 is equipped in a known manner with a cutting wire.
  • the cross conveyor 3 is for taking over the individual strand sections 12 from the third transport path 10 and for transporting them transversely to the extrusion direction through the embossing device 5 and the cutting device 6 intended.
  • the cross conveyor 3 comprises a first cross conveyor section 13 and a second cross conveyor section 14.
  • the first section 13 consists of four individual driven conveyor belts 15 which, starting from the spaces between the individual conveyor belts 11 of the third transport section 10, extend to the embossing device 5 and somewhat above extend out.
  • the number of conveyor belts 16 used in the second transverse conveyor section 14 is equal to the number of blanks 17 to be cut in the cutting device 6 by means of a known wire harp from the respective strand section 12 - sixteen conveyor belts and sixteen blanks in the present exemplary embodiment, so that each conveyor belt 16 is a blank 17 transported away by the cutting device 6.
  • the embossing device 5 consists of an embossing die 18 and a support plate 19 arranged underneath for the individual strand sections 12.
  • the embossing die 18 comprises a pressure plate 20 and an embossing plate 21 which is interchangeably fastened thereon and has a negative pattern incorporated therein (not shown) for embossing a corresponding surface pattern 22a. 22b into the upper strand surface 23 of the respective strand section 12.
  • the pressure plate 20 is guided by means of lifting rods 24 in a mounting block 25 fastened to a frame of the device (not shown) and via these lifting rods 24 from an upper position shown in FIG. 2 to an illustrated in FIG lower pressure position and movable back.
  • a stop 27 for fixing the strand section 12 respectively resting on the support plate 19 in the same, as the embossing position designated position attached below the die 18.
  • the support plate 19 and the stop 27 are provided with transverse grooves through which the four conveyor belts 15 pass, supported by support blocks 28.
  • the support plate 19 with the stop 27 is supported on the frame via a lifting arrangement 31 and can be moved from a lower position below the transport surface 29 of the four conveyor belts 15 into a middle position and then into an upper position and back. In the middle position, the stop 27 projects beyond the transport surface 29 to determine the embossing position.
  • the support surface 30 of the support plate 19 located below the transport surface 29 is arranged in the upper position in the plane of the transport surface 29, so that the support plate 19 together with the four conveyor belts 15 forms a flat surface which supports the respective strand section 12 during the embossing process.
  • the function of the device according to the invention is as follows: By means of the extruder 1 fed with raw material, the raw material strand 7 is extruded, taken over by the first transport path 8 and transported in the strand direction to the separating device 4. In the latter, the raw material strand 7 is separated in a known manner by means of the cutting wire into individual strand sections 12, which are then taken over by the second transport path 9 and are likewise transported in the strand direction until they are completely transferred to the third transport path 10. Each individual strand section 12 is then taken over by the conveyor belts 15 in a known manner and transported transversely to the strand direction or to the previous transport direction into the opened embossing device 5 with the stamp 18 located in the upper position.
  • the first phase is Support plate 19 together with the stop 27 in the lower position, so that the preceding strand section 12, already provided with a surface pattern 22a, 22b - on the right in FIG. 2 - can be transported over the stop 27 onto the conveyor belts 16 by means of the conveyor belts 15.
  • the preceding, already embossed strand section 12 has left the support plate 19, the latter is raised into the middle position, not shown, so that the stop 27 projects into the transport path of the arriving strand section 12 - on the left in FIG. 2 - and the strand section 12 by means of the Conveyor belts 15 can be transported to the stop 27 with its front long side.
  • the support plate 19 is raised together with the stop 27 to the upper position and the die 18 is lowered until it reaches its lower position and thereby Has pressed negative patterns into the upper strand surface 23 and in this way has embossed the corresponding surface pattern 22a, 22b.
  • the stamping die 18 is raised until the upper position is reached and the support plate 19 is lowered into the lower position together with the stop 27, whereupon the stamped strand section 12 is removed from the stamping device 5, as already described.
  • the strand section 12 is held immovably and exactly in the embossing position by the support plate 19 and by the stop 27; at the same time the stamping die 18 is moved exactly perpendicular to the upper strand surface 23 by means of the lifting rods 24. In this way, movements of the negative pattern in its respective plane, ie parallel to the upper strand surface 23, are avoided and thus it is ensured that the embossed surface pattern 22a, 22b corresponds exactly to the negative pattern.
  • the strand section 12 embossed in this way is now transported to the cutting device 6 by means of the conveyor belts 16 and is cut there in a known manner along grooves 32 into blanks 17 by means of the wire harp with cutting wires located in the areas between the conveyor belts 16, which are then cut by means of the conveyor belts 16 be transported away.
  • the grooves 32 have an essentially triangular cross section and are embossed into the upper strand surface 23 together with the surface pattern by means of the correspondingly designed negative pattern. As shown in FIG. 1, the end regions 33 of the individual strand sections 12 are not provided with the surface pattern and, after being cut off, are returned to the extruder 1 by the cutting device 6.
  • the grooves 32 are not shown in order to clarify that this strand section is still in one piece and is only cut into blanks 17 in the cutting device 6. Although these blanks apparently still have the shape of a strand section 12 after leaving the cutting device 6, they should not be confused with them.
  • the lines drawn to differentiate the individual blanks 17 are also not embossed in the upper strand surface 23 Grooves 32 - only shown in Figure 2 - to be confused.
  • the blank 17 shown in FIG. 4 is provided on its upper side with the surface pattern 22a indicated in FIG. 1, consisting of diagonally running and intersecting grooves 34. These grooves 34 end at an uninterrupted circumferential edge 35 of the blank 17 and in this way form a surface pattern limited to one blank each.
  • the upper longitudinal edges of the blank are chamfered with chamfers 36, which have emerged from the grooves 32 in the upper strand surface 23 of the strand section 12.
  • the surface pattern 22b indicated in FIG. 2 is shown in an enlarged representation on the blank 17 according to FIG.
  • the top of this blank is divided into three fields by three grooves 37 running parallel to the blank edges and crossing each other, in which grooves 37 running parallel to the blank edges are in turn arranged in such a way that they form angles in the corner fields and in the intermediate fields U - Form arrangements. All grooves 37 open out freely at the blank edges or the bevels 36, so that they form a surface pattern which can be supplemented and combined to form an overall pattern.
