Definitions
- the invention relates to a method for producing bristle fields for brushes, in particular toothbrushes, wherein bundles of bristles are separated from a bristle supply and transported by means of a gas or air flow and introduced m perforations of a central plate and on a device for producing bristle fields for brushes, with a bristle supply and a device for removing individual bristle bundles from the bristle supply and a transport device for transporting the bristle bundles in perforations of a central plate by means of a gas or air flow.
- Such a method and device is known, for example, from EP 0 405 204 B1.
- several filament bundles m are transported via hoses a carrier plate.
- the filament bundles are then fused to a thermoplastic carrier plate and / or encapsulated with plastic material to form a brush head.
- the degree of filling of the perforations of the filament bundle receiving form is due to the supply of bristle bundles by means of a gas or air flow, relatively low, since the leads for the bundle transport by gas or air flow allow only a limited degree of filling, without clogging the supply lines or individual filaments remain during transport in the supply line.
- the degree of filling is the ratio of the hole cross section of a plate to the sum of all held in this hole filament cross sections.
- the solution according to the invention with respect to the method consists in removing the bristle bundles from the central plate, transferring them into a compacting plate and thereby increasing the bristle density of the bristle bundles.
- the bundles of bristles are compacted, that is to say the entire bristle bundle is slightly reduced in terms of its outer circumference, thus reducing the distance between the individual bristle filaments of a bundle of bristles.
- the bristle bundles held in the central plate can first be transferred to a contour plate, wherein individual bristle bundles of the central plate are combined to form a common larger bristle bundle in the contour plate and / or the cross section of individual bristle bundles is modified, and the bristle bundles are then removed from the contour plate transferred to the compactor plate.
- a contour plate you can Rere small bristle bundles summarized into a larger bundle and / or particular bundle contours, such as elliptical or star-shaped, can be achieved, corresponding to the desired bristle field of the finished brush.
- complex bristle fields for example, with larger contiguous bristle areas feasible.
- individual bristle filaments When transporting the bundles of bristles by means of a gas or air flow into the central plate, individual bristle filaments can be conveyed faster than others, or individual bristle filaments can be retained during the transition to the central plate, so that they are offset longitudinally relative to one another within the central plate Bristle filaments can be located.
- the bristle filaments offset in the axial direction can be pushed together within a perforation of the central plate by means of hole pins which can be inserted into the perforations of the central plate.
- the bristle bundles are profiled at their ends of use and cut off flush at their ends facing away from the end of use.
- a simple profiling of the bristle field is possible, for example, by means of profiling pins acting on the bundles of bristles or a profiled plate having a counter profiling.
- An elaborate profiling after spraying the bristle carrier or brush body by shearing the free bundle ends is not required.
- the bristle bundles After compacting in the compressor plate, the bristle bundles can be overmolded with plastic material, wherein a higher injection pressure is possible without the spray material is forced through the bristle filaments.
- the bristle bundles can also be first melted at their attachment ends before they are sprayed with spray material, which further reduces the risk of over-molding in the bundle region.
- Melting or encapsulation can take place directly in the compressor plate. However, it is also possible to previously transfer the bundles of bristles from the compactor plate into a mold cassette.
- the invention is characterized in that the central plate is followed by a compressor plate having holes for receiving bundles of bristles whose cross sections are each smaller than the cross section of the bristle bundle fed to the respective perforation, and in that a device for passing on the Bristle bundle is provided by the central plate to the compressor plate.
- the compressor plate is arranged downstream of a contour plate, wherein the contour plate has perforations, at least one of which is dimensioned for receiving at least two boron bundles of the central plate and / or has a cross section deviating from the cross section of the corresponding perforation of the central plate.
- the bundles of bristles are first transferred from the central plate to the contour plate where individual bundles of bristles can be combined to form a common larger bundle of bristles or the bristle bundles can be provided with a special outer contour, for example oval or star-shaped, corresponding to the desired bristle field of the finished brush ,
- the bundles of bristles thus shaped by means of the contour plate are then passed on into the compactor plate, where the bristle bundles are compacted as described above.
- a transfer device for transferring the bristle bundles from the contour plate is provided in the compressor plate. After contouring of the bristle bundles m of the contour plate, it is moved into the area of the transfer device and the contoured bundles of bristles are transferred into the compactor plate, for example by means of perforated pins insertable into the perforations of the contour plate.
- the contour plate and the compressor plate in the longitudinal direction of the perforations of the contour plate can be arranged one behind the other and the device for passing the bristle bundles from the central plate in the contour plate can also be designed to pass the bristle bundles to the compressor plate.
- the transfer of the bristle bundles from the central plate into the contour plate and from there into the compactor plate takes place in a single operation, whereby the transfer especially fast can be done and can realize a space-saving and structurally simple construction of the device.
- the contour plate can be designed in a particularly space-saving manner since it only has to have a slight extension in the bristle longitudinal direction in order to reshape the bristle bundles but not to hold them, since the bristle bundles are passed through the contour plate directly into the compactor plate.
- the transport device can have at least one hollow line for a bristle bundle.
- the discharge-side end of the hollow conduit and the central plate can be positioned relative to each other to successively fill all holes of the central plate with bristle bundles.
- the transport device has a number of perforations of the central plate adapted number of hollow tubes.
- all holes can be filled at the same time.
- Individual hollow conduits may also have two or more line sections for receiving a bristle bundle from the bristle supply, which combine on the discharge side to form a wider, common line section so as to fill individual larger perforations in the central plate with a corresponding amount of bristle filaments.
- the hollow tubes are hoses made of flexible material.
- hoses made of plastic can be used.
- the hollow pipes can also be pipe joints made of steel, stainless steel or other metal.
- Plastic tubes require a certain material thickness in order to withstand the pressure during bundle transport by means of gas or air flow.
- hollow pipes made of metal whose material thickness and thus their outer diameter may be smaller, so that they can be arranged closer together at the end and the perforations of the central plate can also be set tighter.
- the central plate can have smaller overall dimensions, which reduces the space requirement of the device, and bristle fields with bristle bundles arranged closer to one another are possible.
- the transport device has a holder for the ends of the hollow tubes facing away from the bristle supply and a vacuum chamber arranged at a distance therefrom for generating a negative pressure, that the central plate between the holder and the vacuum chamber can be arranged and that within the vacuum chamber Baffle plate is arranged as a stop for the introduced into the perforations of the central plate bristle bundles.
- the bristle bundles are then conveyed through a vacuum generated by the vacuum chamber m the central plate. So that the bristle bundles remain m of the central plate and are not further sucked into the vacuum chamber, a baffle plate is provided, to which the bristle bundles abut and are thus held in an end position.
- the baffle plate to change the distance between see bounce plate and central plate be movably mounted.
- the suction power of the gas or air flow can be controlled via the distance between the central plate and the baffle plate.
- the bristle bundles By approaching the baffle plate to the central plate until it rests against this, the bristle bundles can be pushed back completely into the perforations of the central plate after transport, so that the central plate positioned with the bristle bundles to the device for passing the bristle bundles to the compressor plate or the contour plate can be.
- the perforations of the central plate, the contour plate and / or the compressor plate each have a bevel on the insertion side.
- the bristle supply may have multiple material feeds for different bristle material. For example, so brushes can be made with bristle bundles of different materials or in different colors.
- the closer environment can be subjected to ionized air.
- a pulsating air pressure can act on the bristle bundles, with a counterplate acting on the bundles in the central plate. withholds.
- the backing plate can serve as a support for the bundles and reciprocate.
- pins There may be one or more pins.
- One or more pens are held together in one or more pen holders.
- a pin guide plate ensures that the pins are held precisely over the holes.
- the pins can push the bundles together into a bundle.
- a counter plate prevent the bundle from leaving the hole during the pushing together.
- a bundle can get a homogeneous alignment of the individual filaments by uniform reciprocation of the pins and the counter-plate.
- a carrier plate may be provided for receiving the bundles, the bundles being pushed into the carrier plate. Before the pins penetrate into the perforation, the carrier plate is positioned below the central plate. The collapse of individual bundles into a common bundle takes place only in the carrier plate. A stop plate can serve to retain the bundles in the carrier plate.
- the closer environment of the support plate can be acted upon with ionized air.
- the pins can be different lengths and / or have a corresponding oblique or curved contour and a counter plate have a corresponding counter contour.
- the counter-plate can be removed after pushing together the bristle bundles and a cutting edge can cut off the protruding filaments below the central plate.
- the counter contour can also be formed with counter pins within the perforations.
- the bristle bundles can be pushed out of a compartment plate with a slide.
- One or two slides can remove a bundle from the compartment plate below or above the compartment plate.
- An insertion funnel can serve to receive the bristle bundles. This can lower over the bristle bundles and remove the bristle bundles from the compartment plate.
- a counterpart can keep a bunch of bristles clamped against the compartment plate and / or against the slider.
- the suction hose can be pushed in the hose holding plate next to the passage of the feed funnel and thus a vacuum can already be created in the suction hose before the bundle is removed.
- the tube can be pushed in front of the opening of the insertion funnel.
- the hoses can be connected to the mold plate with the geometric shapes of the hoses matching the geometric shapes of the apertures in the mold plate.

- Fig. 28 is a plan view of the arrangement of Fig. 27, and
- Fig. 29 is a perspective view of the arrangement according to Figure 27 with spaced-apart removal plate and contour plate.
- a device designated overall by 100 for producing bristle areas for brushes has according to FIG. 16 a bristle stock 101 and a device 102 for removing individual bristle bundles 5 from the bristle stock 101 and a transport device 103 for transporting the bristle bundles 5 in holes 22 of FIG Central plate 21 by means of a gas or air flow.
- the falling down of the bundle of bristles 5 is prevented by a bottom plate 9.
- the distance D1 a between circular arc or circular disk 6 and the insertion funnel 3 must be designed so that the bristle bundles 5 can move freely below the insertion funnel 3.
- the sliding plate 8 abuts against the bristle bundle 5.
- the suction hose 1 is held in a hose holding plate 2. While through the suction hose 1 by suction (Pf1) a VA is made, the underside of the tube holding plate 2a and the top of the insertion funnel 3a abut each other.
- the suction tube 1 is placed over the insertion funnel 3.
- the counterpart 7 releases the clamping in the direction Pf5b and the bottom plate 9 reduces the distance D2a to D2b in the direction of Pf7 and thus pushes the bundles of boron 5 into the suction hose. 1
- the bottom plate 9 can be brought to the original position in the direction Pf8.
- Fig. 7 shows the suction process of the bristle bundles 5.
- the bristle bundles 5 are transported in the direction of Pf1 in the holes 22 of the central plate 21 to the baffle plate 23.
- the inlet chamfer 22a of a perforation 22 of the central plate 21 parts of the bristle bundle 5 can be retained.
- the bristle bundle 5 is divided into two sections: the projecting bundle 5a, which abuts against the bounce plate 23 and the projecting bundle 5b.
- Vacuum chamber 26a permanently removed. The air is removed from the central plate 21 in the direction of Pf10 around the baffle plate 23.
- porous baffle plate 23 may additionally by the
- Sealing plate 24 m direction Pf11 air are removed from the central plate 21.
- About the movement of the sealing plate 30 in the direction Pf13 can be
- Air amount, which is withdrawn from the central plate 21, are controlled.
- the guides 27 of the sealing plate 30 ensure that the sealing plate 30 is not twisted.
- the distance D7 between the central plate 21 and the baffle plate 23 is very important. If the distance D7 is set too low, the amount of air is insufficient to pull all the filaments m the central plate. If the distance D7 is set too far, filaments of the bristle bundle 5a can be bent over and sucked into the vacuum chamber in the direction Pf10.
- the baffle plate 23 is guided with the guide 28 within the guide 27 of the sealing plate 30.
- the guides could also be done separately.
- a ring ventilation should take place at the bottom 0 20a of the mold plate 20. This ensures that during the aeration the bristle bundles 5b are not pushed back into the tube 1. Ventilation of the central plate 21 via the hoses 1 and the insertion funnel 3 is also possible, but takes longer. 5
- the pulsation of the air pressure Pf15 ensures that in the transition region between the bundles 5a and the bundles 5b, the filaments easily slide into one another (FIG. 5c, FIG. 11). The pulsation of the air pressure Pf15 must take place until
- Fig. 11 is at the top 21 a of the central plate 21, a pin package with pin guide plate 43 c, individual pins 43 b and Stump holder 43a.
- the counter-plate 42 rests against the central plate 21 again.
- the counter-plate 42 of FIG. 10 can be exchanged for another counter-plate in Fig. 11.
- Fig. 13 the counter-plate 42 is replaced by a support plate 45 with respect to FIG.
- a stop plate 47 At a distance D12 from the support plate 45 is a stop plate 47.
- the pins 43b press the bristle bundles 5d in the support plate 45 until they are present at the stop plate 47.
- the chamfer 46 m of the carrier plate 45 facilitates the insertion of the bristle bundles 5 d into the carrier plate 45.
- FIGS. 17 and 18 The pushing together of the partial bristle bundles 5a, 5b to form a regular bundle of bristles 5 within the central plate 21 is also shown in FIGS. 17 and 18, similar to the representation of FIGS. 11 and 12.
- Em such a larger bundle of bristles 5 can be composed, for example, according to Figure 16 by means of a Y-type branched hollow line 104a of two smaller bundles of bristles 5 from the bristle supply 101.
- the hollow conduits 104, 104a of the device 100 according to FIG. 16 are hoses made of flexible material, which allows a simple and flexible mounting and is inexpensive. Nevertheless, a safe and reliable transport of the bristle bundles 5 is ensured.
- the central plate 21 is followed by a contour plate 105 and a compressor plate 106, in which the bristle bundles 5 are transferred by means of the pins 43b.
- the contour plate 105 has perforations 107, of which a perforation 107a for receiving two bundles of bristles 5 of the central plate 21 is dimensioned. This makes it possible to achieve bristle fields with differently sized bristle subfields, for example areas with elongated bristle sections.
- the bristle bundles 5 are pushed further directly m a compactor plate 106.
- Their perforations 108 each have a cross section which is smaller than the corresponding perforation 107 of the contour plate 105, which can be seen in FIG. 20 in particular.
- the bristle density of the bristle bundles 5 is increased, that is, the individual filaments 109 of the bristle bundles 5 are closer to each other and have a smaller distance from each other.
- the bristle bundle 5 is avoided during the later encapsulation of the attachment ends, that pressed even at higher injection pressures plastic material between the individual filaments and the brush is thus unusable.
- the individual pins 43b with the pin holding plate 43a and the pin guide plate 43c according to FIG. 19 form a common device 110 for passing the bristle bundles 5 out of the central plate 21 into the contour plate 105 and the compacting plate 106.
- the bristle bundles 5 are first transferred from the central plate 21 into the contour plate 105, and that the contour plate 105 is moved on to a further processing station, where the bristle bundles are transferred into the compactor plate 106 with a separate transfer device.
- FIGS. 26 to 29 show a sectional view of a removal plate 111 and the downstream contour plate 105.
- Figure 26 shows a bottom view and Figure 28 is a top view. As can be seen, in particular, from the perspective view according to FIG.
- the perforations 107 of the contour plate 105 each have different cross sections than the corresponding holes 112 of the removal plate 111
- the cross section or the outer contour of the bristle bundles is changed.
- round bundles of bristles for example, can be converted into hexagonal, rectangular or elliptical bundles of bristles or rectangular bundles of round bristles.
- the bristle bundles in the contour plate 105 After the forming of the bristle bundles in the contour plate 105, they can be compacted as described above by further conversion into a compacting plate.
- the contour plate 105 is removed (Fig.21), so that the bristle bundles 5 are held only in the compressor plate 106. Subsequently, the utility-side ends of the bristle bundles 5 are acted upon in accordance with FIG. 22 with a profile plate 113. In order to ensure a defined position of the individual filaments 109 of the bristle bundles 5, the bristle bundles 5 are acted on from the opposite side with a counter-profile plate 114. After the removal of the counter profile plate 114 (FIG. 23), the bristle bundles 5 are cut flush with the surface of the compressor plate 106 on their side remote from the use-side ends with a knife 115 (FIG. 24). After removal of the profiled plate 113 (FIG. 25), the profiled bristle bundles 5 can be transferred, for example, to a shaping plate which is used for injection-molding the fastening-side bundle ends and for spraying a brush head or brush body.
- FIG. 14 shows how different hose systems, single hose 1, double hose 52 and triple hose 53 are fastened to a mold plate 20. Any number of multiple hoses are conceivable. Due to the multiple hoses, individual bundles can be brought together as shown in direction Pf1.
- bristle bundles are supplied with gases, liquids or powder via an additional line.
- a corresponding spacer pin is attached to the baffle plate. This dummy pin has the approximate length of bundle 5a and bundle 5b together.
- the tube 1 of the first bundle 5 extends beyond: 0 the entire perforation 22. During the first filling, the spacer pin holds the space for the second filling free.
- the tube for the second filling is placed over the hole 22.
- the hose should correspond in cross section to the! 5 spacer pin and be positioned above it.
- the merging of the bundles 5a and 5b does not lead to i ⁇ mixing of the two fillings.
