Definitions

  • the invention relates to a method and an apparatus for producing striped, multi-colored soap. Such methods and devices have long been known.
  • a device for producing at least two-colored striped soap bars from a continuously extruded soap strand is known from German patent specification 28 39 967, in which at least one outlet pipe of a second press screw opens approximately concentrically with the soap stream conveyed by a first screw and flows into the center thereof a distributor with a central inlet chamber is arranged at the mouth of the outlet pipe. From this central inlet chamber, radially outward pipe-like spokes extend, possibly including an axial extension component, the downstream walls of which are provided with outlet openings for at least one further soap stream.
  • Such a device can be used to produce a soap bar that is alternately colored through to the center, the structure of the device being quite simple and conventional extrusion machines being able to be converted.
  • No completely colored soap bar can be achieved with a method and a device according to German Offenlegungsschrift 24 26 492.
  • this method solid strands of other soap extending in the longitudinal direction are embedded within and along the surface of the base soap strand, and the moving composite soap mass is largely one subjected to uniform radial compression and extruded.
  • a conventional extrusion press which transports the base soap and has a cone at the screw end, essentially serves as the device for carrying out this method.
  • the second soap is embedded in the main soap stream via an annular channel arranged on the circumference of the compression head with a plurality of projections which extend radially inwards and are closed at the bottom and on the sides and have outlet openings (nozzles) which are open in the direction of the outlet mouthpiece.
  • German patent specification 28 39 967, columns 2 to 4 contains a summary of the relevant prior art for devices for the production of multi-colored striped soap bars.
  • a ring element serving as an ink supply station is known, to which a number of nozzle holders are attached, which extend radially inward into the soap stream.
  • the ring member has an annular passage for connection to a source of colored liquid.
  • the annular passage communicates with the nozzle holders.
  • the ink supply station is a device for supplying colored solutions into a soap and not a device for supplying a second mass of soap. As a result, when using such a device, a marbled soap bar results.
  • German laid-open specification 22 01 326 a method and a device for producing differently colored soap is known, the device having the special feature that a cutting device is provided in the compression chamber behind a perforated plate, which is driven by a shaft connected to the extrusion press.
  • the marbled appearance of the soap is achieved by rotating the cutting knife.
  • the stream of soap is separated from the blades of the cutting knife and conveyed in the radial or transverse direction by the moving other soap mass.
  • the invention is therefore based on the object of providing a method which allows the production of striped, multicolored soap in a wide variety of patterns.
  • the invention is based on the further object of providing a device which, using the advantageous supply of the second soap composition from radially outside to radially inside, permits the production of striped, multicolored soaps with a wide variety of patterns.
  • the rotational movement results in an approximately helical course of the strips.
  • the variation in the speed of the rotational movement changes the stripe pattern in such a way that the pitch of the screw thread changes, while wave patterns of the stripes can be generated by changing the direction of rotation of the rotational movement.
  • a suitable combination of the parameters of speed and direction of rotation of the rotational movement can be used to generate a large number of patterns of the strips in the soap.
  • the motor-driven distributor ring rotatably mounted in the ring channel enables the additional soap mass flowing through the ring channel of the device to be rotated by the rotating soap mass dispensers attached to the distributor ring while being brought together with the first soap mass.
  • the drive of the distributor ring is particularly simple if the soap mass outputs extend up to a cylinder located in the fluid axis and serving as a hub, which is connected to an outside of the shaft via a shaft attached to it Cone is connected to the drive located in the back.
  • Any type of drive for example hydraulic or electric drives, can be considered as the drive.
  • a drive arranged outside the device is also conceivable, which drives the shaft via a chain.
  • the radially inward longitudinal extent of the soap mass dispenser to be substantially larger than its width and to open it in the direction of the mouthpiece from the distributor ring to close to Let the fluid axis approach. This results in a particularly uniform flow of the soap masses to be introduced via the soap mass dispensers, and an extremely good pressure distribution, which ensures a consistently good quality of the solid-colored strips.
  • the production of soaps with more than two colors, which are striped and patterned according to the invention, can be realized with the device according to the invention in a simple manner in that the ring channel is divided into different mutually impermeable sections, and each section with at least one pressing device for a soap mass with a different color. Due to the rotary movement of the individual soap mass dispensers together with the distributor ring, the soap masses introduced through their respective openings alternate in color, as a result of which, for example, strips can be produced with colors alternating over the course of the strip.
  • a mouthpiece with an essentially rectangular cross-section placed on the mouth of the outlet cone has the effect that the rotational movement of the exiting soap strand is terminated.
  • the method and the device according to the invention can also be used to produce striped multicolored products other than soap in various patterns, provided that the starting materials of these products correspond to or are similar to those of soap compositions in terms of their nature and in particular their extrudability.
  • the device consists of a first screw press S1 with a press screw 1, which is held in a cylinder 2 by a drive (not shown) rotatable about its longitudinal axis.
  • the cylinder 2 is followed by an outlet cone 4, which has a mouthpiece 5 which forms the emerging soap strand at the front.
  • the parts 1, 2, 4 and 5 mentioned so far are the components of a conventional soap extrusion machine.
  • the press screw 1 continuously promotes a soap mass of a certain color, which emerges through the outlet opening 6 of the mouthpiece 5 into a strand.
  • the aim of the invention is to provide a device which, using the advantageous supply of a second soap composition from radially outside to radially inside, permits the production of striped, multicolored soaps with a wide variety of patterns.
  • a further screw press S2 is connected, which has a press screw provided with its own rotary drive.
  • the cylinder of the second press screw is connected via a pipe 8 to an annular channel 9 arranged on the circumference of the cone 4.
  • the ring channel 9 is held between the parts 4a, 4b of the outlet cone 4 each opening into flanges 11a, 11b. Screw connections 12 between the two flanges 11a, 11b of the outlet cone 4 clamp the ring channel 9 and let it become part of the outlet cone 4.
  • a distributor ring 13 is rotatably arranged, which essentially consists of a U-shaped ring adapted to the shape of the cone, from which several soap mass outputs 14 open in the direction of the mouthpiece 5 of the cone 4 and fed by the ring channel 9 extend .
  • the soap mass outputs 14 are part of the distributor ring 13 (see FIG. 2).
  • the longitudinal extent L of the soap mass dispensers 14 is substantially larger than their width B, as can be seen from FIG. 2.
  • the depth of the openings 15 of the soap mass dispensers 14 remains constant radially inwards.
  • the opening 15 of each soap mass dispenser 14 extends from the inner surface 28 of the cone to close to the fluid axis M (cf. FIG. 1).
  • the soap mass outputs 14 In the vicinity of the fluid axis M, the soap mass outputs 14 converge in a cylinder 20 serving as a hub for the distributor ring 13 and merging into a cone 17 on its end face.
  • the cone 17 tapers downstream and causes in connection with the tapered inner conical surface 28, the soap flow displaced in the center due to the diameter of the shaft 18 and the drive 19 now moves again in the direction of the fluid axis M and can close in the middle.
  • Both the soap mass 21a from the soap mass outputs 14 and the soap mass 21b of the press screw 1 are subjected to the flow movement towards the center, so that sharply delimited zones of differently colored soap are formed in the mouth region 5, 6.
  • the shaft 18 connecting the distributor ring 13 to the schematically illustrated drive 19 is so long in the exemplary embodiment that the drive 19 can be arranged in the cylinder 2 of the device.
  • the arrangement of the soap mass dispensers 14 at a distance from the fluid axis M offers not only the advantage of simple mounting of the drive shaft 18, but also the further essential advantage that a large number of soap mass dispensers 14 can be distributed over the circumference of the distributor ring 13 without Due to a lack of space in a narrow area around the fluid axis M, arrangement difficulties could arise (cf. FIG. 2). Nevertheless, due to the shape of the outlet cone 4, a soap strand colored through to the axis of the fluid is achieved (cf. FIGS. 4, 5).
  • the drive 19 is reversible in its direction of rotation and infinitely variable in speed.
  • strips can be made in the extruded strand, for example as shown in FIGS. 4 and 5, produce.
  • any other pattern of the strips in the extruded soap strand can also be produced.
  • baffle plate 23 shown in FIG. 3.
  • baffle plate 23 is arranged in the flow direction between the distributor ring 13 and the mouthpiece 5 of the outlet cone 4 and, via the surfaces 24 tapering the cross section of the outlet cone 4, produces a different pressure distribution over the soap stream, which results in special patterns and also marbling.
  • the baffle plate 23 prevents the entire soap flow in the outlet cone 4 from rotating. At the same time, it causes different wave patterns in the soap mass.
  • the above-described device is therefore particularly well suited for carrying out the method according to the invention, because the supply of the second soap mass 21a via the ring channel 9 has the essential advantage that the pressure of the soap mass 21a is highest in the area of the inner cone surface 28, which is particularly important sharp delimitation of the soap masses 21a, 21b on the surface of the extruded soap strand, which is primarily important for the sale of a bar of soap.
  • the method according to the invention can advantageously also be implemented on other devices for producing striped, multicolored soap, in that the second soap mass is introduced Elements are rotated. For this purpose, a more or less great design effort is required, whereby design difficulties can arise in moving the drive back and sealing the moving part against the static supply of the second soap mass in individual cases.
  • the sealing problem is realized in a simple manner by means of a labyrinth seal which is arranged between the distributor ring 13 and the ring channel 9 and is not shown in detail in the figures and which is known to be extremely pressure-stable.
