Description
Methode voor het produceren van ankerloze borstels, meerbepaald tandenborstels.Method for producing anchorless brushes, in particular toothbrushes.
In recente jaren hebben tandenborstels, gemaakt zonderhet gebruik van metalen fixeermiddelen voor de vezels,aan populariteit gewonnen. Eén methode voor hetproduceren van dergelijke borstels bestaat erin omgebruik te maken van een dragerelement (1) met doorgaandeopeningen, waardoor vezels (2) geschoven worden. Dezevezels (2) worden aan één kant van het dragerelement metelkaar verbonden door middel van warmte. Hetdragerelement (1) met de vezels (2) kan daarnaonverbrekelijk aan een tandenborstellichaam wordenverbonden, of een tandenborstellichaam kan aan hetdragerelement worden gecreëerd, bvb door middel vanspuitgieten. Het tandenborstellichaam zal dan die zijdevan het dragerelement (1) , waar de vezels (2) met elkaarzijn verbonden, minstens gedeeltelijk bedekken.In recent years, toothbrushes made without the use of metal fixers for the fibers have gained popularity. One method for producing such brushes is to make use of a carrier element (1) with through-openings, through which fibers (2) are slid. These fibers (2) are joined together on one side of the carrier element by means of heat. The carrier element (1) with the fibers (2) can then be inextricably connected to a toothbrush body, or a toothbrush body can be created on the carrier element, for example by injection molding. The toothbrush body will then at least partially cover the side of the carrier element (1), where the fibers (2) are connected to each other.
Technieken voor het produceren van dergelijke borstelsworden reeds beschreven in de octrooien EPS0972464 enEPS0972465 van de aanvrager.Techniques for producing such brushes are already described in the applicant's patents EPS0972464 and EPS0972465.
Het is belangrijk voor de kwaliteit van de tandenborsteldat de vezels goed aan de borstel zijn verbonden, zodathet losbreken van vezels tijdens het poetsen vermedenwordt. Losbreken van de vezels tijdens het poetsen kanleiden tot inslikken van de vezels door de gebruiker, enverdere complicaties. Om de controleren of de vezels opeen correcte wijze met de tandenborstel verbonden zijn,kan men discrete destructieve controles uitvoeren - devezels lostrekken door het dragerelement, en dan debenodigde krachten meten om dit te doen. Deze methode vernietigt echter de gecontroleerde producten en geeftgeen zekerheid over de gelijkmatigheid van de krachtbenodigd om de vezels van de tandenborstel los tetrekken.It is important for the quality of the toothbrush that the fibers are properly connected to the brush, so that the breaking of fibers during brushing is avoided. Loosening of fibers during brushing can lead to swallowing of fibers by the user, and further complications. In order to check whether the fibers are correctly connected to the toothbrush, one can perform discrete destructive checks - pulling the fibers through the carrier element, and then measuring the forces required to do this. However, this method destroys the controlled products and does not provide assurance on the uniformity of the force required to pull the fibers off the toothbrush.
Indien de gesmolten vezelmassa (3) wordt afgedekt doormiddel van spuitgieten, zoals geïllustreerd in figuur 6en 8, kan het ook nuttig zijn om deze gesmoltenvezelmassa (3) te inspecteren op dichtheid, om zo tevermijden dat de toegevoegde kunststofmassa (5) door degesmolten vezelmassa (3) heendringt en tussen devezels(2) van de borstels uitsteekt.If the molten fiber mass (3) is covered by injection molding, as illustrated in Figures 6 and 8, it may also be useful to inspect this molten fiber mass (3) for leaks, so as to prevent the added plastic mass (5) from being melted fiber mass ( 3) penetrates and protrudes from the brushes (2) of the brushes.
Aangezien de vezels (2) met elkaar worden verbonden doormiddel van warmte, en dat het werd ontdekt dat de vorm ende afmetingen van de laag gesmolten vezelmateriaal (3)een direct verband heeft met de sterkte van de verbindingvan de vezels, is het mogelijk om de gelijkmatigheid vande trekkracht nodig om de vezels van de borstel los tetrekken te controleren door de vorm en de afmetingen vande laag gesmolten vezelmateriaal (3) te inspecteren. Hetis bijzonder voordelig om deze inspectie te integreren inde productiestappen van de tandenborstel, omdat op diemanier vermeden wordt dat door destructieve testsmaterialen of goede borstels worden vernietigd.Since the fibers (2) are connected to each other by heat, and it has been discovered that the shape and dimensions of the layer of molten fiber material (3) has a direct relationship with the strength of the connection of the fibers, it is possible to uniformity of the tensile force required to detach the fibers from the brush by inspecting the shape and dimensions of the layer of molten fiber material (3). It is particularly advantageous to integrate this inspection into the production steps of the toothbrush, because in this way it is avoided that destructive test materials or good brushes are destroyed.
De inspectie van de gesmolten vezelmassa (3) kancontactloos gebeuren, bijvoorbeeld door middel vantriangulatietechnieken, waarbij door een opnemer (6) eendigitale meetpuntenwolk (7) van het oppervlak van degesmolten vezelmassa wordt opgenomen en in een digitaleverwerkingseenheid (8) wordt vergeleken met eenreferentiebeeld, zoals ook geïllustreerd in figuur 9.Afhankelijk van ingestelde toleranties kan dan de borstel goed- of afgekeurd worden en uit het productieprocesverwijderd worden. Alternatief kan de inspectie ookgebeuren door middel van een camera (6) die een beeld vande gesmolten vezelmassa (3) neemt en dit vergelijkt meteen referentiebeeld, zoals geïllustreerd in figuur 10.The inspection of the molten fiber mass (3) can be done without contact, for example by means of triangulation techniques, in which a sensor (6) records a digital measuring point cloud (7) from the surface of the melted fiber mass and compares it in a digital processing unit (8) with a reference image, such as also illustrated in figure 9. Depending on the set tolerances, the brush can then be approved or rejected and removed from the production process. Alternatively, the inspection can also take place by means of a camera (6) that takes an image of the molten fiber mass (3) and compares this with a reference image, as illustrated in figure 10.
Het beeld (9) kan de kleuren van de gesmolten vezelmassa(3) bevatten, of het kan een warmtebeeld zijn dat dewarmteverdeling in de gesmolten vezelmassa (3) toont, wateen maat kan zijn voor de hoeveelheid gesmoltenvezelmassa (3) en haar verdeling.The image (9) may contain the colors of the molten fiber mass (3), or it may be a thermal image showing the heat distribution in the molten fiber mass (3), which may be a measure of the amount of molten fiber mass (3) and its distribution.
Zoals geïllustreerd in figuur 11 en 12 kan de inspectievan de gesmolten vezelmassa (3) ook via contact met hetoppervlak gebeuren, bijvoorbeeld door middel van één ofmeerdere meetstiften (10) die contact maken met deoppervlakte van de gesmolten vezelmassa (3). De positie(11) van iedere meetstift (10) kan dan vergeleken wordenmet een referentiepositie in een verwerkingseenheid (8),zoals geïllustreerd in figuur 12.As illustrated in Figures 11 and 12, the inspection of the molten fiber mass (3) can also take place via contact with the surface, for example by means of one or more measuring pins (10) which make contact with the surface of the molten fiber mass (3). The position (11) of each measuring pin (10) can then be compared with a reference position in a processing unit (8), as illustrated in Figure 12.
Na de inspectie is het product onbeschadigd, en kan hetmet het afdekkend gedeelte worden verbonden, hetzijonmiddellijk, of op een later tijdstip. De dragers metvezels kunnen ook als los verkocht worden, met debedoeling dat de eindgebruiker deze op een steel (4)monteert en zo de gesmolten vezelmassa (3) afdekt.After the inspection, the product is undamaged and can be connected to the covering part either immediately or at a later time. The carriers with fibers can also be sold separately, with the intention that the end user mounts them on a handle (4) and thus covers the molten fiber mass (3).
