Description

Beschreibung: Description:
Schutzbekleidung, insbesondere Schutzhandschuh.Protective clothing, in particular protective gloves.
Technisches Gebiet:Technical area:
Die Erfindung betrifft eine Schutzbekleidung gemäß dem Oberbegriff des Patentanspruchs 1 , insbesondere einen Schutzhandschuh.The invention relates to a protective clothing according to the preamble of patent claim 1, in particular a protective glove.
Stand der Technik:State of the art:
Der Einsatz von Schutzbekleidung ist in vielen Bereichen weitverbreitet und dient im Allgemeinen dem Schutz der die Bekleidung tragenden Person. Auf manchen Gebieten steht auch der Schutz einer Person oder eines Produkts im Vordergrund, zu der oder dem der Kontakt hergestellt wird. So ist beispielsweise in der Nahrungsmittelindustrie die Einhaltung hygienischer Vorschriften vorrangig, um sicherzustellen, dass Nahrungsmittel frei von Fremdstoffen und Keimen zum Konsumenten gelangen. Entsprechendes gilt für die Pharmazie, wo das oberste Gebot darin besteht, Medikamente frei von Verunreinigungen herzustellen und abzupacken. Im medizinischen Bereich stellt sich zusätzlich die Problematik des Schutzes der die Schutzbekleidung tragenden Person vor Infektionen.The use of protective clothing is widespread in many areas and generally serves to protect the person wearing the clothing. In some areas, the protection of a person or product to which contact is made is also in the foreground. For example, in the food industry, compliance with sanitary regulations is paramount to ensuring that food is free of foreign substances and germs from the consumer. The same applies to pharmacy, where the top priority is to produce and package medicines free of impurities. In the medical field, in addition, the problem of protecting the person wearing the protective clothing from infections.
In diesem Zusammenhang bekannte Schutzbekleidungen sind vielfältiger Natur und umfassen Handschuhe, Kopfhauben, Mundschutze, Schürzen und dergleichen. Die Verwendung derartiger Schutzbekleidung in der herstellenden Industrie bringt jedoch die Gefahr mit sich, dass sich infolge äußerer Einwirkung Materialteilchen aus der Schutzbekleidung lösen und ungünstigstenfalls in den Produktstrom gelangen, mit der Folge, dass auf diese Weise mit Fremdstoffen verunreinigte Produkte, wie zum Beispiel Nahrungsmittel oder Medikamente in Umlauf gebracht würden. Um dies mit Sicherheit ausschließen zu können, sind Betriebe bereit, große Chargen aus der Produktionskette auszusondern, in der Annahme, dass sich der gesuchte Fremdstoff in dieser Charge befindet. Speziell in der Nahrungsmittelindustrie werden in vielen Produktionsabschnitten Lebensmittel auf einem Förderband transportiert und gleichzeitig verarbeitet, beispielsweise werden nicht verwertbare Bestandteile von verwertbaren Bestandteilen von Hand getrennt und ausgesondert. Aus hygienischen Gründen trägt das damit befasste Personal eine Schutzbekleidung zu der auchProtective clothing known in this context is of a variety of nature and includes gloves, hoods, mouth guards, aprons, and the like. The use of such protective clothing in the manufacturing industry, however, entails the risk that, as a result of external action, particles of material will detach from the protective clothing and, in the worst case, get into the product stream, with the result that products contaminated with foreign substances, such as foodstuffs or so Medicines would be circulated. In order to be able to exclude this with certainty, companies are ready to discard large batches from the production chain, assuming that the desired foreign substance is in this batch. Especially in the food industry, in many production stages, food is transported on a conveyor belt and processed at the same time, for example, non-recyclable constituents of usable constituents are separated by hand and separated out. For hygienic reasons, the personnel involved wear a protective clothing too
Schutzhandschuhe gehören. Derartige Schutzhandschuhe bestehen für gewöhnlich aus Gummi oder PVC und umschließen die Hand aufgrund ihrer großen Elastizität und geringen Dicke wie eine zweite Haut und werden daher kaum wahrgenommen.Protective gloves belong. Such protective gloves are usually made of rubber or PVC and enclose the hand because of their great elasticity and small thickness as a second skin and are therefore hardly noticed.
Beim Arbeiten mit solchen Handschuhen ist es nicht auszuschließen, dass sich aufgrund äußerlicher Einwirkung ein Bestandteil aus dem Handschuh löst und unbemerkt in den Nahrungsmittelstrom gelangt. Wenn die dadurch bedingte Verunreinigung der Nahrungsmittel erst beim Wechseln der Schutzbekleidung auffällt, ist eine Eingrenzung der davon betroffenen Charge nur noch innerhalb großer Grenzen möglich. Um mit Sicherheit die Verunreinigung aus demWhen working with such gloves, it can not be ruled out that due to external influences, a component will come off the glove and pass unnoticed into the food stream. If the consequent contamination of the foodstuffs is noticeable only when the protective clothing is changed, it is only possible to narrow down the batch affected by this within wide limits. To be sure the pollution from the
Nahrungsmittelstrom wieder zu entfernern ist es daher notwendig, eine große Menge ansonsten einwandfreier Ware als Ausschuss zu behandeln und auszusondern, was natürlich nicht ohne Auswirkungen auf die Wirtschaftlichkeit eines davon betroffenen Betriebs bleibt.It is therefore necessary to remanufacture a large amount of otherwise perfect goods as rejects and to discard them, which of course does not have any impact on the profitability of an affected establishment.
Darstellung der Erfindung:Presentation of the invention:
Vor diesem Hintergrund besteht die Aufgabe der Erfindung darin, Schutzbekleidungen derart weiterzuentwickeln, dass sich die beschriebene Problematik nicht oder nur in einem wesentlich verminderten Umfang einstellt.Against this background, the object of the invention is to develop protective clothing such that the problem described does not or only to a significantly reduced extent.
Diese Aufgabe wird durch eine Schutzbekleidung mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved by a protective clothing having the features of patent claim 1.
Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen. Der Erfindung liegt die Erkenntnis zugrunde, dass durch Verkürzung der Reaktionszeit von der Kontamination des Produktionsguts bis zur Ergreifung geeigneter Gegenmaßnahmen die als verunreinigt in Frage kommende Charge auf eine Größe reduziert werden kann, die sich wirtschaftlich nicht mehr nennenswert auswirkt.Advantageous developments emerge from the subclaims. The invention is based on the finding that, by shortening the reaction time from the contamination of the product to the taking of suitable countermeasures, the batch considered as contaminated can be reduced to a size which no longer has a significant economic impact.
In Umsetzung dieses Gedankens sieht die Erfindung vor, Schutzbekleidung derart weiterzuentwickeln, dass Bestandteile dieser im Produktstrom mit Hilfe einer Detektionseinheit ohne menschliches Zutun erfassbar sind. Durch die erfindungsgemäßen Modifikationen an der Schutzbekleidung ist eine unmittelbare maschinelle Erfassung von Teilen der Schutzbekleidung im Produktstrom erstmals möglich. Eine zu diesem Zweck geeignete Detektionseinheit kann beispielsweise oberhalb eines Förderbandes angebracht sein und den darunter passierenden Produktionsstrom mittels geeigneter Sensoren überwachen. Im Sinne der Erfindung geeignete Sensoren sind induktive oder kapazitive Sensoren oder auch Magnetfeldsensoren, die möglichst unmittelbar stromabwärts einer Bearbeitungsstation angeordnet sind.In implementing this idea, the invention provides further development of protective clothing such that constituents of the latter can be detected in the product stream with the aid of a detection unit without human intervention. Due to the modifications of the protective clothing according to the invention, a direct mechanical detection of parts of the protective clothing in the product stream is possible for the first time. A detection unit suitable for this purpose may, for example, be mounted above a conveyor belt and monitor the production flow passing below by means of suitable sensors. According to the invention suitable sensors are inductive or capacitive sensors or magnetic field sensors, which are arranged as directly as possible downstream of a processing station.
Um die automatische Erfassung durch die Detektionseinheit zu ermöglichen, sieht die Erfindung eine Beimengung geeigneter Partikel in einer einheitlichen Verteilung über die gesamte Schutzbekleidung vor. Durch die Beschaffenheit der Partikel ist es den Sensoren möglich, Teile der Schutzbekleidung im Produktstrom zu detektieren. Durch die einheitliche Verteilung ist sichergestellt, dass jedes beliebige Teil einer Schutzbekleidung die mit den Sensoren zusammenwirkenden Partikel aufweist. Auf diese Weise werden mit sehr hoher Sicherheit und innerhalb kürzester Zeit Fremdkörper im Produktstrom erkannt, so dass sich die mit Fremdkörpern belastete Charge innerhalb enger Grenzen ermitteln lässt. Die als Ausschuss zu entsorgende Charge bleibt daher gering.In order to enable automatic detection by the detection unit, the invention provides for admixture of suitable particles in a uniform distribution over the entire protective clothing. Due to the nature of the particles, it is possible for the sensors to detect parts of the protective clothing in the product stream. The uniform distribution ensures that any part of a protective clothing has the particles interacting with the sensors. In this way, foreign bodies are detected in the product flow with a very high level of safety and within a very short time, so that the charge loaded with foreign bodies can be determined within narrow limits. The batch to be disposed of as waste therefore remains low.
Von der Erfindung bevorzugt verwendete Partikel bestehen aus Edelstahl. Diese stehen in großen Mengen zur Verfügung und sind daher kostengünstig verfügbar. Edelstahlpartikel zeichnen sich zudem durch eine gute Detektierbarkeit aus, so dass Bestandteile damit ausgerüsteter Schutzbekleidungen sehr zuverlässig von entsprechenden Sensoren erkannt werden.Particles preferably used by the invention are made of stainless steel. These are available in large quantities and are therefore available at low cost. Stainless steel particles are characterized by a good detectability, so that Components thus equipped protective clothing are reliably detected by corresponding sensors.
Durch Verwendung austenitischen Edelstahls ist der Einsatz induktiver oder kapazitiver Sensoren möglich. Hingegen erlaubt die Verwendung ferritischer Partikel auch den Einsatz von Magnetfeldsensoren. Es ist auch möglich, unterschiedliche Sensoren in einer Detektionseinheit anzuordnen um eine möglichst hohe Detektionsrate zu erzielen.By using austenitic stainless steel, the use of inductive or capacitive sensors is possible. By contrast, the use of ferritic particles also allows the use of magnetic field sensors. It is also possible to arrange different sensors in a detection unit in order to achieve the highest possible detection rate.
Gemäß einer vorteilhaften Ausführungsform der Erfindung beträgt der Partikelanteil an der Schutzbekleidung mindesten 15 Gew.-%. Da die Detektion allein von den Partikeln in der Schutzbekleidung abhängt, kann durch eine stärkere Anreicherung von Partikeln in der Schutzbekleidung die Detektionssicherheit erhöht werden, beziehungsweise die Sensibilität der Detektionseinheit gesteigert werden, da die Sensoren bei einem höheren Partikelanteil auch sehr kleine Bestandteile der Schutzbekleidung erfassen.According to an advantageous embodiment of the invention, the proportion of particles in the protective clothing is at least 15% by weight. Since the detection depends solely on the particles in the protective clothing, the detection reliability can be increased by increasing the accumulation of particles in the protective clothing, or the sensitivity of the detection unit can be increased, since the sensors also detect very small components of the protective clothing with a higher particle content.
Die Größe der einzelnen Partikel liegt vorzugsweise unter 100 μm, wobei durch geeignete Wahl des Partikeldurchmessers ein Schwebezustand der Partikel in der Herstellungsmasse der Schutzbekleidung erzielt wird. Es wird somit ein Sedimentieren der Partikel in der Herstellungsmasse und damit Entmischen verhindert, mit dem Vorteil, dass die Partikel gleichmäßig verteilt in der Herstellungsmasse vorliegen und daher auch eine erfindungsgemäße Schutzbekleidung eine entsprechende Verteilung der Partikel aufweist mit den oben beschriebenen Vorteilen.The size of the individual particles is preferably less than 100 microns, which is achieved by appropriate choice of the particle diameter levitating the particles in the manufacturing mass of the protective clothing. It is thus a sedimentation of the particles in the production composition and thus segregation prevented, with the advantage that the particles are uniformly distributed in the manufacturing mass and therefore also a protective clothing according to the invention has a corresponding distribution of the particles with the advantages described above.
Die Erfindung wird im Weiteren am Beispiel eines Gummihandschuhs näher erläutert. Zur Herstellung eines solchen Handschuhs wird natürlicher oder synthetischer Kautschuk in eine flüssige bis zähflüssige Konsistenz gebracht. In diese Kautschukmasse werden dann etwa 15 Gew.-% oder mehr Edelstahlpartikel eingemischt, wodurch eine Suspension entsteht. Dabei sind die Partikel in Größe, Form und Gewicht so auf die Suspension abgestimmt, dass eine Sedimentation der Partikel und damit Entmischen der Suspension unterbleibt.The invention will be explained in more detail below using the example of a rubber glove. To produce such a glove, natural or synthetic rubber is brought to a liquid to viscous consistency. In this rubber compound then about 15 wt .-% or more stainless steel particles are mixed, creating a suspension. The particles are in size, Shape and weight so matched to the suspension that sedimentation of the particles and thus demixing the suspension is omitted.
Die Formgebung des Schutzhandschuhs erfolgt dann mittels entsprechend geformter Tauchkörper, die in die Kautschukmasse getaucht werden und an denen die anhaftende Suspension zum Vulkanisieren gebracht wird. Der so hergestellte Schutzhandschuh zeichnet sich somit durch eine gleichmäßige Partikelverteilung aus. Solche Handschuhe eignen sich beispielsweise zur Verwendung als Hygienehandschuhe in der Nahrungsmittelindustrie.The shaping of the protective glove is then carried out by means of suitably shaped immersion bodies, which are immersed in the rubber composition and at which the adhering suspension is vulcanized. The protective glove thus produced is characterized by a uniform particle distribution. Such gloves are suitable, for example, for use as hygiene gloves in the food industry.
Löst sich nun beim Arbeiten mit solchen Handschuhen ein Bestandteil aus dem Handschuh und gelangt dabei in den laufenden Lebensmittelstrom, so passiert dieser Bestandteil auf dem Förderband die der Bearbeitungsstation nachgeordnete Detektionseinheit, deren Sensoren auf die Partikel in dem Bestandteil ansprechen und ein Signal an eine Steuereinheit geben. Die Steuereinheit verhindert daraufhin, dass die mit dem Fremdkörper befrachtete Charge an Lebensmittel imIf, when working with such gloves, a component is released from the glove and enters the current food stream, this component on the conveyor belt passes the detection unit downstream of the processing station whose sensors respond to the particles in the component and send a signal to a control unit , The control unit prevents the batch of food contaminated with the foreign body from being contaminated
Lebensmittelstrom verbleibt. Dies kann durch Anhalten des Förderbandes und Alarmieren des Bedienpersonals geschehen, das dann von Hand die betroffene Charge entsorgt. Es ist aber auch möglich, durch das Vorsehen einer Weiche im Produktionsstrom die unbrauchbar gewordene Charge auszusondern. Food flow remains. This can be done by stopping the conveyor belt and alerting the operator, who then manually disposes of the affected batch. But it is also possible to eliminate the useless become charge by providing a switch in the production flow.
