Description

Apparatus for manufacturing a bristle set for a brush, a device series of this type and a method of manufacturing this type of device

The present invention relates to a set of bristles for brushes, in particular to an apparatus for manufacturing a toothbrush, which is characterized in that the bristle bundle is carried by a gas or air stream through at least one hollow tube of the conveying device into the through- A bristle set manufacturing device having a carrying device for a bristle set.

The present invention also relates to a series of devices for making bristles, in particular bristle sets for toothbrushes, and to a method of manufacturing devices of the type defined above.

Devices of the type mentioned at the outset are known in practice as different embodiments. In such a device, bristle bundles are conveyed through a hollow tube to a bundle holding plate. Bristle bundles, also known as filament bundles, are overmolded, for example, with a thermoplastic carrier plate and / or a plastic material to form the brush head. In this case, individual bristles generally have a round cross-section. However, in the toothbrush, a more complex shaped bristle with a non-circular cross-section, at least the individual bristle bundles may be, for example, rectangular or triangular, is desired. In order to be able to supply a bristle bundle having a cross-sectional shape different from that of the ring-shaped band, it is known to use, for example, a hollow tube known as a geometric conduit, which is usually used in an elliptical shape. However, such shape tubes are only available in a limited number of simple cross-sectional shapes and have the disadvantage of being relatively complex and expensive to manufacture and procure.

It is an object of the present invention to create an apparatus, a series of apparatus and a method for manufacturing a device or a series of apparatuses of the type mentioned at the outset, and to easily and cost-effectively manufacture and design many modified apparatuses and a series of apparatuses I will.

According to the invention, this object is achieved by an apparatus according to claim 1. According to the present invention, an apparatus for manufacturing a bristle brush, in particular a toothbrush, is proposed, in which a gas or air stream is introduced through at least one hollow tube of a conveying device into a through hole of a bundle fixing plate, And a guide element installed at a fixed interface between the discharge end of the hollow tube and the discharge line. And a bundle fixing plate, wherein the discharge end of the at least one hollow tube is provided with a through hole in a bundle fixing plate held in a mounting preparation state in which at least one continuous guide duct connectable or connectable with a lead is formed through the inflow end and the discharge end, Wherein the guide element and the at least one continuous guide duct are generated.

The use of a production method for producing a guide element and at least one continuous guide duct in which the bristle bundles can be fed to the bundle clamping plate enables the production of guide elements with efficient and cost-effective wide guide ducts. And various cross-sectional shapes. In addition, the complicated shape of at least one guide duct inside the guide element can be made less complex and therefore cheaper with the help of the production method compared to conventional manufacturing methods, for example casting or injection. / Or cores are generally required. Moreover, the flexibility with respect to the cross-sectional shape of the at least one guide duct in the interior of the guiding element can be increased by means of the productive manufacturing method, since the various shapes can be relatively easily produced and produced and manufactured, - geometric aspects of the workpiece, as may be the case for conventional manufacturing methods, such as forming techniques.

The guide element may be a suction block manufactured by a generative manufacturing method. At least one guide duct in the interior of the guiding element can have a circumferentially closed inner wall so that the bristle bundle can be reliably carried, in particular inhaled, through at least one hollow tube connected to the guiding element, And at least one guide duct by negative pressure applied to the suction block.

Advantageously, said at least one guide duct may be a guide duct formed in the material of said guiding element during manufacture of the guiding element by a generative manufacturing method, and preferably extending in said guide along its entire length. In this way, at least one guide duct of the guiding element and guiding element can be manufactured in a single manufacturing step.

The generating and generating method by which the guide element and at least one guide duct can be obtained can be a 3D printing method.

A common 3D printing method is known, for example, as a powder bed method, a free space method, or a liquid material method.

The powder bed method that can be applied to produce the guide element and at least one guide duct of the device according to the invention is selective laser melting, selective laser sintering, selective heating sintering, binder spraying or electron beam melting.

Known free-space methods include fusion modeling, laminate modeling, build-up welding, cladding, wax deposition modeling, shape generation, cold spraying or electron beam melting.

The liquid material method that can be used to manufacture the guide element and at least one guide duct is a stereolithography technique, a digital light treatment or a liquid composite molding.

In this case, the guide element may be made of a plastic material, a ceramic material or a metal.

When supplying bristle bundles having different cross-sectional shapes, it is possible that the inner contour of at least one hollow tube is delivered to the discharge end of the hollow tube when bristle bundles carried in that path are transferred. From the hollow tube to the guide duct of the guiding element, there is a change in the contour towards the bundle outline required in the bristle set.

Of course, the inner contour of at least one guide duct in the guiding element may exhibit a change from outline to out at the course from the inlet end to the outlet end.

In this embodiment of the device according to the invention, the profile of bristle bundles can occur during transport in hollow tubes and / or guide ducts. Thus, no additional device is needed to form the bristle bundles delivered to the bundling fixture, and no additional space is required for such a device.

In an embodiment of the device according to the invention, the guiding element which particularly benefits from the possibilities associated with the use of the generating member generating method is that the guiding element is made to have two or three guiding ducts, And more inlet ends and inlet-duct portions leading to the outlet end of one guide duct. In this embodiment of the device according to the invention, the supply of bristle bundles carried to the guiding element through two or more hollow tubes is possible in the through holes of the bundle fixing plate.

A plug-in opening for receiving at least one hollow tube may be provided in order to reliably connect at least one hollow tube of the conveying device to at least one guide duct of the guide element. The discharge end of said at least one hollow duct is pluggable or pluggable into said plug-in opening and preferably permits interruption and uninterrupted movement of the bristle bundle carried into the guide duct of the guiding element through said inner diameter hollow tube Guide at least one guide duct of at least one guide duct to correspond to the inner diameter of at least one hollow tube.

It may be particularly desirable that an inlet chamfer is formed on the inlet opening at the inlet end of the at least one guide duct and the inlet chamfer makes it easier for the supplied bristle bundle to enter the inlet end of the guide duct from the hollow tube. And is connected to the at least one guide duct through the inlet opening.

The at least one hollow tube may have a circular or circular cross section, especially at the discharge end. However, it is also possible to use a hollow tube with a cross-sectional profile, especially a polygonal cross-section. Advantageously, said inlet opening of at least one guide duct and / or at least one inlet duct portion of at least one guide duct is, for example, a transverse section of a hollow tube. This can deliver the carried bristle bundle from the hollow tube to the guide duct connected to the hollow tube of the guide line with little or no breakage.

The at least one hollow tube may preferably be a tube made of a flexible material or preferably a pipe connection made of a plastic material or metal, especially steel or stainless steel. The use of flexible tubes as hollow tubes, especially those made of plastic materials, can enable a structurally simple and cost-effective structure of the device.

In particular, the use of hollow tubes made of pipe connections made of metal, such as steel or stainless steel, can withstand higher operating pressures during bundle transportation compared to hollow tubes made of plastic materials of equal or smaller wall thickness. Due to the gas or air flow, therefore, the material thickness of these hollow tubes is smaller, so that the outer diameter can be dimensioned to be smaller than the outer diameter so that the ends of the hollow tube are disposed close to each other and the discharge ends. When a plurality of hollow tubes are used, the attachment positions of the hollow tubes can be arranged close to each other. Especially when a plurality of hollow tubes are used, this can reduce the required size of the guiding element.

In order to facilitate delivery of bristle bundles carried by the guiding element to the perforations of the bundle holder plate, holes in the bundle holder plate may be provided to accommodate bundle bundles formed on the hollow tube, or each guide duct may be provided in a desired bundle contour Can be contoured in a corresponding manner. The bristle bundle carried through at least one guide duct is chamfered at the edge of the through hole of the bundle fixing plate facing the guide element at the mounting position of the bundle fixing plate.

It should be noted that, with regard to the bundle fastening plate, it may be a cassette for insertion into a mold, a carrier plate or a sealing plate of an injection-molded tool known in the art. Such a carrier plate or seal plate is a bundle fixing plate that can be inserted into the head of the toothbrush, in particular, the head of the toothbrush and connected to the brush.

In particular, in order to ensure the connection of at least one hollow tube to the guide element during operation of the device according to the invention and to avoid disconnection between the at least one guide duct and the at least one hollow tube, It may be convenient to have holders for tubes. The holder may be disposed on the guiding element by at least one support member. The holder can be configured as a fixed plate having a retaining opening for at least one hollow tube and is designed to be numerically and geometrically matched to the number and geometry of the hollow tube to be retained.

The device may have a removal device for removing individual bristle bundles from the bristle supply and bristle supply. A conveying device for conveying the removed bristle bundles to the conveying device can also be provided on the device according to the present invention.

When the conveying device has a plurality of hollow tubes corresponding to the number of through holes of the bundle fixing plate, it is possible to particularly efficiently mount the bundles of bristles supplied to the bundle fixing plate. It may also be convenient to have the outlet ends of the plurality of guide ducts corresponding to a plurality of guide ducts, the guide elements corresponding to the number of through-holes in the bundle-fixing plate, in particular the number of through-holes in the bundle support. In this way, with the aid of the device according to the invention, it is possible to mount all the through holes of the bundle fixing plate at the same time to the bundle of bristles carried through the hollow tube of the guide element and the guide duct.

This object is also achieved by means of a series of apparatus for manufacturing a bristle set for a brush as claimed in claim 16. To achieve the object, therefore, there is provided a set of bristles for a brush, in particular a series of devices for manufacturing a toothbrush, comprising at least two devices as claimed in any one of claims 1 to 15, The guide elements of the device are designed differently in terms of their design, in particular in relation to the number of their guide ducts, or have a cross-sectional geometric shape of the guide duct and / or of the guide duct, The interfaces of the devices are configured to be identical to each other.

In a series of similar devices according to the invention which are similar but different in design of the guiding element, they can be exploited throughout manufacturing-related advantages with the use of generative manufacturing methods for producing guiding elements and guide ducts located therein.

In principle, since these devices are manufactured in very few numbers, it was previously very complex and costly to provide guidance elements of very different designs. In the manufacturing methods previously used for manufacturing guide elements such as injection molding or metal-casting techniques, it has always been necessary to first produce expensive tools and to provide guide elements of different design with differently designed guide ducts It was very expensive and complicated. In the series according to the invention, as a result of the use of the inventive manufacturing method in the production of the guiding element, such drawbacks can be largely avoided. For example, by a conventional CAD program. The manufacture and manufacture of complex tools for manufacturing different guiding elements can be avoided.

In order to achieve the above object, the present invention also provides a method for manufacturing the apparatus according to any one of claims 1 to 15, wherein the apparatus first prints it using a 3D printing method, Which is installed in the fixed interface of the apparatus.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the drawings.

Figures 1 and 2 illustrate an apparatus generally designated 1 for manufacturing bristles for a brush, particularly a toothbrush. The device 1 has a conveying device 2 for conveying bristle bundles through a hollow tube 3 by a gas or air stream into the through holes 4 of the bundle. Such a bundle clamping plate 5 is shown in Figs. 1 and 2 and can be prepared on the device 1 to have bristle bundles.

The conveying device 2 includes a guiding element 6 installed in a fixed interface 7 between the discharge end 8 of the hollow tube 3 and the bundle fixing plate 5. [ The stationary interface 7 can be formed on the device 1, for example on the upright part 9 of the device 1. [

The guide element 6 is provided with at least one continuous guide duct 10 through the inlet end 11 at the discharge end 8 of the hollow tube 3 of the conveying device in use, The duct 10 is inserted through the outlet end 12 into the through hole 4 of the bundle fixing plate 5 held in a mounting ready state. In this way the bristle bundle carried by the gas or air stream through the hollow tube 3 of the conveying device 2 is guided by the guiding element 6 and the at least one guiding duct 10 formed in the guiding element , Into the through hole 4 of the prepared bundle fixing plate 5, and in this way a desired set of bristles can be produced.

According to the invention, the guiding element (6) and the at least one continuous guiding duct (10) are manufactured by a manufacturing method. In this case, the guiding element 6 and the at least one continuous guiding duct 10 may be layered by a production method which may be referred to as a 3D printing method. The layering of the guiding element 6 and the at least one continuous guide duct 10 can take place in or parallel to the subsequent transport direction of the bristle bundle through the at least one guide duct 10, It is preferable to laminate the guide element 6 and the at least one continuous guide duct 10 transversely with respect to the subsequent conveying or conveying direction of the bristle bundle to be conveyed through the duct 10. In particular, a particularly complex cross-sectional shape of at least one continuous guide duct 10 in this way may be realized inside the guide element 6. [

All the guiding elements 6 shown in Figs. 1 to 6 consist of a suction block 13 manufactured by a generative manufacturing method. At the outlet end 12 of the guide duct 10 of the suction block 13 shown in the drawing a negative pressure can be applied which can carry, or at least promote, the bristle bundle by gas. The hollow tube 3 of (2) ) And the guide duct (10).

It can be seen that each guide duct 10 has a circumferentially closed inner wall 14, based on the guiding duct 10, shown in phantom and extending inside the individual guiding element 6. The guide duct 10 is formed in the material of the guiding element 6 in the same manufacturing step by the manufacturing method that occurs during the manufacture of each specific guiding element 6 and is guided along the entire length into the guiding element 6 It is a duct.

As a manufacturing method in which the guide element 6 and the guide duct 10 can be manufactured or obtained, what is known as the 3D printing method can be used. A powder bed method, a free space method, or a liquid material method can be used to produce the guiding element 6 and the at least one guiding duct 10 provided therein, depending on the material and application to be processed.

Known powder bed processes are, for example, selective laser melting, selective laser sintering, selective heat sintering, binder spraying or electron beam melting.

Known free-space methods include fusion deposition modeling, laminate modeling, build-up welding, cladding, wax deposition modeling, contour creation, cold spraying or electron beam melting.

Known liquid-phase material methods are, for example, stereolithography, digital light processing or liquid-liquid composite molding.

All the production methods are distinguished by the fact that the guide element 6 and the at least one guide duct 10 are produced directly on the basis of a computer-in-house data model from an amorphous material such as, for example, liquid, powder, . Or shape-neutral materials, such as strip-shaped or wire-shaped materials, can be prepared by chemical and / or physical methods. A particular aspect of the production process is that the guiding element 6 according to the invention and the guiding duct 10 provided therein are the main forming methods that can be manufactured without the specific tools for reproducing the specific geometry of the desired guiding element 6 and a guide duct 10 formed therein, which is necessary for this purpose as in the casting mold used for casting.

The guide element 6 shown in the figures may be made of a plastic material, a ceramic material or preferably a metal, as desired.

In all of the guide ducts 10 shown in the drawings, the inner contour of the guide duct 10 is required to be changed in the set of bristles of the contour in the path from the inlet end 11 to the outlet end 12 of the guide duct 10 Towards the outline of the bundle.

The guiding element 6 shown in Figures 1, 2 and 3 has a total of nine guide ducts 10 having different guiding duct cross-sections. In this case, seven of the nine guide ducts 10 have a circular guide duct cross-section at least in the region of the inlet end 11, and the two central guide ducts 10 have a square and rectangular cross-section, respectively. ).

It can be seen here that the guide duct 10 has the same cross section in the region of the inlet end 11, such as the hollow tube 3 attached to the guide duct 10. This guides the hair bundle into the guide duct 10 with little or no damage to the hollow tube 3).

The guide element 6 shown in Fig. 4 has four guide ducts 10, and the first guide duct 10a shows the change of the outline from the round inlet cross-section to the hexagonal outlet cross-section. The second guide duct 10b shows a change in the inner contour from the circular cross-section to the rectangular cross-section from the inlet end 11 to the outlet end 12. The third guide duct 10c indicates a change in cross section from a relatively large square cross-section to a smaller cross-section from the elevation 11 to the outlet end 12, in this case the bristle bundle is conveyed through the guide duct 10 At the same time. The fourth guide duct 10d of this guiding element 6 changes its inner contour from its inlet end 11 to its outlet end 12 in the rectangular inlet cross-section to a rectangular outlet cross-section, .

In all of the guide ducts 10, 10a, 10b, 10c and 10d shown in the figure, the cross-sectional area decreases from the inlet end 11 to the outlet end 12 of each specific guide duct, , 10a, 10b, 10c, 10d are compressed during transport.

The guide element 6 shown in Figures 5 and 6 is characterized in that the guide ducts 10 formed in these guide elements 6 each have two or three inlet ends 11 and a corresponding number of inlet- 15, the two inlet ends 11 of the guide duct 10 in this case form an outlet duct section 16 and the guide duct 10, The outlet end section of the outlet is round. The outlet end face of the outlet end 12, in which the two inlet duct portions 15 of the guide duct 10 are connected, is formed in an elliptical shape.

The guide element 6 according to FIG. 6 is provided with three guide ducts 10 or inlet-duct portions 15, each of which has a circular inlet cross-section. The three inlet duct portions 15 are integral to form the outlet duct portion 16 and are ultimately directed to the triangular outlet cross-section at the outlet end 12 of the outlet duct 10 or the outlet duct portion 16.

A plug-in opening 17 having a clearance for connecting and accommodating each hollow tube 3 is provided adjacent to the inlet end 11 of the guide duct 10 . The hollow tube 3 is inserted into these plug-in holes 17 to securely fix the hollow tube 3 to the guide element 6.

The figure clearly shows that the inlet internal cross-section of the guide duct 10 adjacent each discharge end 8 of each hollow tube 3 coincides with the discharge internal cross-section of the corresponding hollow tube 3. From (8) An inlet chamfer 19 is formed on the inlet opening 18 at the inlet end 11 of each guide duct 10 to supply the bristle bundles into the respective guide ducts 10.

In both of the interconnecting hollow tube 3 and the guide duct 10, the cross section for the inlet opening 18 of each guide duct 10 and the inlet-duct portion 15 of each specific guide duct 10 is a cross- Is located in the region of the hollow tube (3), especially at the discharge end (8).

In this case, the hollow tube 3 has a circular or circular cross-section, or a cross-section, in particular a polygonal cross-section, contoured at the discharge end 8 as desired.

According to the application example, the hollow tube 3 may preferably be constructed as a tube composed of a flexible material. In particular, the pressure-resistant hollow tube 3 can be constituted as a pipe connection part made of, for example, a plastic material or a metal, in particular, steel or stainless steel.

In order to facilitate the movement of the bristle bundles from the outlet end 12 of the guide ducts 10, 10a, 10b, 10c and 10d into the penetrating portion 4 of the bundle fixing plate 5, (6) of the through hole (4) in the through hole (4) is chamfered.

The through hole 4 of the bundle fixing plate 5 for accommodating bristle bundles formed in one of the hollow tubes 3 or one of the guide ducts 10, 10a, 10b, 10c, It corresponds to the bundle contour. In this way, a set of bristles is produced, the arrangement of the through holes 4 in the bundle fastening plate 5 and the cross-sectional geometry followed.

The bundle clamping plate 5 may be constructed as a cassette for insertion into a mold of an injection-molding tool, as a carrier plate or as a sealing plate, according to the application example. The carrier plate or sealing plate is a bundle fixing plate 5, which can be inserted into the head of the brush, in particular the head of the toothbrush, and is connectable thereto with a brush.

Figures 1 and 2 show that the device has a holder 20 for the hollow tube 3 of the conveying device 2. The holder 20 is arranged and fixed on the guiding element 6 by means of four supporting joints 21.

The holder 20 is configured as a clamping plate having a retaining opening 22 for the hollow tube 3 and the retaining opening 22 is designed to be numerically and geometrically matched to the number and geometry of the hollow tubes 3 to be retained do.

Although not shown in the drawing, it is true that the device 1 may have a removal device for removing the bristle supply and individual bristle bundles from the bristle supply. The device 1 may also have a conveying device for conveying the removed bundle to the conveying device 2 so as to be able to supply the bristle bundle to the through hole 4 of the bundle by the conveying device 2, 5 remain in the ready state.

At least the guide element 6 shown in Figures 1 to 3 comprises a plurality of outlet ends 12 having an outlet opening of the guide duct 10 corresponding to the number of through holes 4 in the bundle holder plate 5 to be mounted, , All the through holes 4 present in the bundle fixing plate 5 shown in Figs. 1 and 2 can be provided with bristle bundles at the same time with the aid of the device 1 according to the invention.

An exemplary embodiment of the guide element 6 shown in Figs. 1, 2 and 3 has a plurality of guide ducts 10 corresponding to the number of through holes 4 of the bundle clamping plate 5.

A compressor plate not shown in the drawing can be disposed downstream of the bundle holder plate 5, and a portion of the compressor plate has a through hole for receiving bristle bundles. In this case, the cross section is smaller than the cross section of the bristle bundle delivered to each through hole, in this case smaller than the cross section of the corresponding through hole 4 in the bundle plate 5 located upstream. In addition, the device according to the invention may have an advance conveying device for forwardly transferring the bristle bundles from the bundle clamping plate 5 to the compressor plate downstream.

The device 1 according to the invention can form a series of devices for producing bristles for brushes, in particular toothbrushes, which comprise at least two devices 1 of this type. In this series, the guide elements 6 of at least two devices 1 are constructed differently in terms of their design, in particular in terms of the number of guide ducts 10 and / or the water surface of the guide duct 10. [ The fixed interfaces (7) of at least two devices (1) in which the guide elements (6) are installed in the use position are constructed identically to one another.

This makes it possible to quickly switch the device 1 according to the invention in this way by installing different guiding elements 6 shown in Figures 3 to 6 also on the device 1 shown in Figures 1 and 2 .

In this connection, it is possible to take full advantage of the advantages of the manufacturing method, since the guide elements 6, which can be produced with difficult or high levels of expenditure in the prior art methods, can now be produced relatively easily with relatively little effort There is a need for complex shapes and complex internal shapes that do not require particularly complex tools.

In this case, in the production of the device (1) according to the invention, each specific guiding element (6) of the device (1) is first printed in one configuration by a generative manufacturing method, in particular by the 3D printing method , And then to the stationary interface 7 of the device 1.

As already mentioned above, the guiding element 6 can be laminated in layers transversely to the subsequent conveying or conveying direction of the bristle bundle through at least one bristle, for example in the case of 3D printing. In this way, a very complicated cross-sectional structure and a cross-sectional geometric process of the individual guide ducts 10 inside the guide element 6 can be relatively easily realized in a single guide element 6.
