Definitions

  • the invention relates to a hair piercing machine for bribing a hair part, in particular toupees, according to the preamble of claim 1.
  • hairpieces for human use are known, which are made from several layers of different materials such as gauze, rubber, celluloid, glass fiber fabric, various plastics, etc. So there is z. B. a known hair piece of four layers. With him, the hair is individually pulled through two upper layers of fabric and attached to the underside of the second layer with an adhesive layer, while another layer of fabric is glued from below against this adhesive mass as a cover.
  • the top layer consists of the scalp of appropriately colored silk gauze.
  • the underlying layer is said to be impermeable to adhesive and water, while the opposite layer is made of silk gauze.
  • a method for producing such hairpieces is known: (DE AS 1 917 993), in which, on a hard positive mold, two auxiliary molds made of thin, transparent plastic film made of PVC, which are deep-drawn onto them, are arranged one above the other, including a grid film, the upper auxiliary mold before laying on and piercing first coat the underside of the hair with a primary synthetic resin film and then pull it up by several millimeters after pulling the hair over it. Then the hair ends stuck in the second (lower) auxiliary form are separated and the first auxiliary form, which now carries the hair alone, is lifted off.
  • the hair pile protruding from the underside of the first (upper) auxiliary form is shaved to a uniform length of about 1 to 2 mm and embedded in synthetic resin by applying a synthetic resin layer on the inside of this first (upper).
  • the first (upper) auxiliary mold is pressed with a separating layer covering the positive mold, which consists of previously applied synthetic resin. Varying the pressing pressure produces a film which forms the hair bottom and is of a uniform thickness, depending on the pressing pressure, correspondingly thicker. After the film has hardened, the auxiliary form is pulled off over the hair.
  • the state of the art include program-controlled placement machines such. B. for boards in which electronic components are used in certain positions of the board.
  • the object of the invention specified in claim 1 is to provide a hair piercing machine which avoids the inadequacies of monotonous and therefore error-causing manual labor during piercing.
  • the development according to claim 8 causes the even hair transport to the piercing needle.
  • the development according to claim 10 ensures that, depending on the need, one or more hairs can be gripped by the piercing needle.
  • the development according to claim 11 ensures that the determined number of hair is ready for insertion.
  • the development according to claim 12 prevents hair from falling out when the hair supply is in a steep position.
  • the development according to claim 13 makes counting the hair easier.
  • the housing 1 is provided with a door 3 and closed on the top with the mounting plate 11. It is surmounted by a guide bend 9 for the piercing head 15 and the hair feed 31 firmly connected to it.
  • the guide curve 9 runs through longitudinal bores 10a and 10b of the mounting plate 11.
  • the ends of the guide arch 9 are firmly connected to the base plate 5 and sit in the recesses 9a and 9b of the base plate 5.
  • the base plate 5 is supported by rollers 7 in roller guides 8 which are attached to the inside of the side frame parts 4.
  • the drive 6, a stepping motor, moves the base plate 5 and thus also the guide bend 9 parallel to the base plate via the rack 6a arranged below the base plate 5.
  • the control device (not shown) for all stepping motors, which converts the values coming from the computer system via cables and passes them on to all drives, is also accommodated in the housing 1.
  • the rollers 7 can also be designed as gear wheels.
  • a holding device 12 is used to fix the positive mold 12a, for which quick-release fasteners with a corresponding counterpart on the positive mold 12a are suitable.
  • the guide bend 9 projects so far over the positive form 12 a that the lancing head 15 (see FIG. 1) - in FIG. 2 only the lancing head rollers 16 are shown with sufficient clearance over the positive form 12 a along the guide bend 9.
  • the lancing head guide 13 is shown in more detail in FIG. 3. It consists of a sled-like part which is connected to the guide bend 9 via lancing head rollers 16 and is driven by the drive 14 for the lancing head guide 13.
  • a further drive 18 is arranged on the slide-like part, which ensures the movement of the piercing head arm 17 in the 2-axis direction.
  • the profiled piercing arm 17 runs next to the guide bow 9 and always moves perpendicular to the tangent of the guide bow during the piercing process. It is therefore always directed directly onto the surface of an assembled positive mold 12 a.
  • the piercing arm 17 has toothed shafts 19 on both sides, in which the drive 18 for the piercing arm 17 engages.
  • the basic idea of the invention comprises two solutions.
  • the positive form is firmly mounted on the mounting plate and all movements are carried out by drives connected to the piercing needle.
  • the kinematic reversal is realized in that only the lancing movement of the needle is triggered within the lancing needle head, but all other adjustments are made to the positive shape.
  • the particular advantage of this solution lies in the fact that all the elements for producing the insertion position can be arranged in the housing of the hair-piercing machine and can be selected primarily according to the requirements of the precise positioning without regard to mass restrictions.
  • the development according to claim 19 causes the even hair transport to the piercing needle.
  • the development according to claim 20 prevents hair falling out, especially when the hair feeder is in a steep position.
  • the development according to claim 21 makes counting the hair easier.
  • the development according to claim 22 ensures that the determined number of hair is ready for insertion.
  • the housing 1 is provided with a door 3 and closed on the top with the mounting plate 11. It is surmounted by a guide bow 9 for the piercing head 15 and the hair feeder 31 firmly connected to it.
  • Fig. 2 shows more precisely how the guide curve 9 runs through longitudinal bores 10 a and 10 b of the mounting plate 9.
  • the ends of the guide arc 9 are firmly connected to the base plate 5 and sit in the recesses 9 a and 9 b of the base plate 5.
  • the base plate 5 is supported by rollers 7 in roller guides 8 which are attached to the inside of the side frame parts 4.
  • the drive 6, a stepper motor, moves over the rack 6 a arranged below the base plate 5, the base plate 5 and thus also the guide bend 9 parallel to the base plate.
  • the housing 1 also houses the control device (not shown) for all stepping motors, which converts the values coming from the computer system via cables and forwards them to all drives.
  • the rollers 7 can also be designed as gear wheels.
  • a holding device 12 is used to fix the positive mold 12 a, for which purpose quick-release fasteners with a corresponding counterpart on the Positive form 12 a are suitable.
  • the guide arch 9 protrudes so far over the positive form 12 a that the piercing head 16 (see FIG. 1) - only the piercing head rollers 16 are shown in FIG. 2 - can be moved along the guide arch 9 with sufficient play above the positive mold 12 a.
  • the lancing head guide 13 is shown in more detail in FIG. 3. It consists of a sled-like part which is connected to the guide bend 9 via lancing head rollers 16 and is driven by the drive 14 for the lancing head guide 13.
  • a further drive 18 is arranged on the slide-like part, which ensures the movement of the piercing head arm 17 in the Z-axis direction.
  • the profiled piercing arm 17 runs next to the guide bow 9 and always moves perpendicular to the tangent of the guide bow 9 during the piercing process. It is therefore always directed directly onto the surface of an assembled positive mold 12 a.
  • the piercing arm 17 has toothed shafts 19 on both sides, in which the drive 18 for the piercing arm 17 engages.
  • FIG. 4 shows the further configuration of the piercing head 15, which is directed toward the piercing needle 29.
  • the hairs are to be pierced exactly perpendicular to the surface (plane) at the puncture point - it is necessary that Align the piercing needle 29 with each piercing process.
  • the swiveling of the rotary head 20 about the constantly changing Y-axis takes place through the drive shaft 23 provided in the rotary head 20 with the gear 24 a in accordance with the direction of rotation
  • the position of the lancing head guide 13 is then corrected.
  • the rotary head 20 is mounted at the lower end of the lancing head arm 17.
  • the drive with the drive shaft 21 serves to pivot the holding plate 25 about the likewise constantly changing X axis, corresponding to the direction of rotation A. and gears 22 a and 22 b and 24 b, the drive shaft 21 works via a worm wheel 28 d with the holding plate 25.
  • Several proximity switches 26 are arranged on the holding plate 25. The inclination (angle of the tangent at the piercing point) and the Distance of the surface of the positive mold 12 a measured The measurement result is used to adjust and align the rotary head 20 and the holding plate 25 about the X or Y axis and the piercing head arm 17 above the positive mold 12 a.
  • a further drive with an eccentric gear 28 including eccentric rod 28 a and eccentric axis 28 b is arranged on the holding plate 25 for the lancing head 15, which acts directly on the needle holder 27 and triggers the actual lancing process.
  • the needle holder 27 penetrates with its upper narrow neck piece the holding plate in the bore 28 c and thereby receives its guidance during the downward movement.
  • the needle 29, the free end of which is designed as a groove 30, is inserted into the needle holder 27 with a quick-release fastener in order to grasp one or more hairs.
  • the hair feeder 31 consists of a distributor shaft 32 into which the hair is inserted in bundles and in which the hair is connected by a distribution arrangement, not shown, e.g. B. by counter-rotating rubber rollers, the endless belt device 33 are fed individually.
  • the endless belt device 33 consists of at least two endless belts, each provided with grooves 34 for one hair each. Two endless belts are arranged directly next to one another in such a way that the piercing needle 29 fits between them during the piercing process.
  • the hair lies on the endless device 33 such that the root end of the hair facing the piercing needle 29 projects above the endless device 33 by about 2 cm.
  • a sensor 35 is provided in the immediate vicinity of the needle 29 and counts the hair. If, for example, not just one hair, but two or more hairs are to be pierced at the same time, the bundle plate 36 arranged at the end of the endless device 33 holds the hair open until the desired number is reached. The hair jammed in the bundle is then gripped together by the notch 30 of the needle 29. The bundle plate 36 bent over at the front end of the endless device 33 is guided towards the distributor shaft as a cover in order to ensure that the hair is held in the grooves even when the hair feeder 31 is not in a horizontal position.
  • the housing 2 of the hair-piercing machine 1 looks largely like the housing of the first embodiment (FIG. 1).
  • the encapsulated lancing head 15 is fixed with the angled holding arm 37, and arranged laterally from him, such that the piercing needle fits between the end of the endless double belt 33 of the hair feeder 31 when piercing.
  • Both the hair feeder 31 with the bundle plate 36 and the distribution chess 32 are also arranged fixedly on the holding arm 37.
  • the elements described in connection with the first exemplary embodiment are used for the machine-operated lancing process (needle holder 27, eccentric drive 28, eccentric rod 28 a, eccentric axis 28 b and needle 29, FIG. 4). Further elements, in particular the various drives, are integrated in the piercing head housing, so that it has smaller dimensions than the movable design according to the first exemplary embodiment.
  • the positive mold 12 a is releasably connected to the drives 44 and 45 (FIG. 6), which are hidden by the sleeve 46, by means of a quick-release fastener (not shown). Although it can only be used once, it must consist of hard but light material, which is not cheap. It is therefore advantageous to design the positive mold 12 a as a stump firmly connected to the drives 44 and 45, on which a positive shell, onto which the hair piece to be bridged is fitted, can be held immovably with known closure means, using the division of the Positive form 12 a in positive stump and positive shell is achieved so that the positive shell can consist of cheap material (e.g.
  • the adjustment means for the position of the positive mold 12 a (or for the positive stump, which also applies to the other versions) are shown in FIG. 6.
  • the drives 44 and 45 each consisting of stepper motor and gearbox, the positive mold 12 a can be tilted around the X-axis and the Y-axis. These movements are necessary when the puncture plane at the puncture point, e.g. B. in the case of bumps in the head shape of the hairpiece wearer is not perpendicular to the piercing needle and must therefore be corrected.
  • a support arm 39 is provided for swiveling the positive mold 12 a including the drives 44 and 45 with a larger radius. It connects the drives 44 and 45 at the required distance to the gear 42 including the adjusting motor for adjusting the height of the positive mold 12 a.
  • the support arm 39 has a rack and is guided in the housing for the gear 41.
  • the gear 41 including stepping motor, the distance between the positive form 12 a and the piercing needle can be changed by the support arm 39 can be moved in the Z-axis, corresponding to the respective direction of the piercing needle.
  • the housing for the gear 41 is firmly connected to a further gear 42 including a stepping motor, as a result of which the support arm 39 with the other elements connected to it (positive form 12 a, drives 44 and 45) about the X axis, that is to say in the direction of rotation D "can be tilted.
  • the gear 43 including the stepping motor, acts on the gear 42, around the entire arrangement (gear 42 to positive shape 12 a) about the Y axis, that is to say in the direction of rotation
  • the adjustment axis of the gear 44 is fastened to the housing 2, see FIG. 47 in FIG. 5, so that the motor of the gear 43 is also tilted.
  • the surface of the positive mold 12 a is first optically scanned and the data, including the size and position of the hair part and the density of the hair, are stored in an EDP system.
  • the data in combination with a special program, provide a three-dimensional image of the hair part on the head and are fed to the hair-piercing machine 1, specifically to the computing device arranged there in the housing 1, which calculates the data for controlling all stepping motors.
