Description

Die Erfindung betrifft eine Vorrichtung gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a device according to the preamble of Claim 1.

Handschuhe aus elastomerem Material werden dadurch hergestellt, daß ent­ sprechende Formen in ein Bad aus einem Elastomer getaucht werden. Sobald der die Form bedeckende Oberzug die entsprechende Dicke aufweist, wird die Form aus dem Bad entnommen. Es erfolgt eine Trocknung und an­ schließend die Entformung des Handschuhs von der Form.Gloves made of elastomeric material are made by ent speaking forms can be immersed in an elastomer bath. As soon as the top cover covering the mold has the appropriate thickness the shape taken from the bathroom. There is drying and on closing the release of the glove from the form.

Dazu werden Greifmittel eingesetzt, mit denen der freie Rand des Hand­ schuhs ergriffen wird, so daß ein Zug auf den Handschuh zum Zwecke der Entformung ausgeübt werden kann. Es handelt sich bei der Entformung um einen durchaus kritischen Vorgang, da bei einem auch nur leichten Ein­ reißen des Elastomers eine Beschädigung des Handschuhs beim Entformungs­ vorgang resultiert.For this, gripping means are used with which the free edge of the hand shoe is gripped so that a pull on the glove for the purpose of Demolding can be exercised. The demolding is a very critical process, since even a slight on tearing of the elastomer will damage the glove during demolding process results.

Bei einer bekannten Vorrichtung der gattungsgemäßen Art (GB-PS 14 87 191) werden Düsen zur Entformung des Handschuhs verwendet, welche im Bereich der Handschuhöffnung einen Luftstrahl zwischen Form und Handschuh rich­ ten und zwar auf einen durch von außen auf den Handschuh aufgesetzte Klemmen abgegrenzten Bereich. In den dadurch nach außen aufgeblähten Handschuhbereich wird dann ein übliches Greiforgan eingesetzt, um den Handschuh von der Form abziehen zu können. Der Einsatz von Düsen und das Anlegen von Klemmleisten ist jedoch aufwendig und auch zeitraubend, so daß diese bekannte Vorrichtung insbesondere mit Hinsicht auf eine Massenfertigung solcher Handschuhe mit entsprechenden Nachteilen be­ haftet ist. Es besteht bei dieser Vorrichtung somit die Gefahr, daß man zur Beschleunigung der Produktion mit hohen Taktzeiten fährt und dann die Trocknungsperiode nicht richtig abwartet, wodurch es aber zu Beschädigungen des Handschuhs selbst beim Entfernen kommen kann.In a known device of the generic type (GB-PS 14 87 191) nozzles are used to remove the glove from the area the air gap between the form and the glove rich on one by putting it on the glove from the outside Terminals delimited area. In the blown up as a result A standard gripping device is then used to glove the area To be able to remove the glove from the form. The use of nozzles and however, the creation of terminal strips is complex and also time-consuming, so that this known device in particular with regard to a Mass production of such gloves with corresponding disadvantages is liable. There is therefore a risk with this device that one drives at high cycle times to accelerate production and then the drying period does not wait properly, but it does  damage to the glove can occur even when removed.

Aufgabe der Erfindung ist, eine Vorrichtung der eingangs genannten Art zu schaffen, welche eine beschädigungsfreiere Entformung von insbesondere dünnwandigen Handschuhen aus elastomerem Material von einer Form vereinfacht.The object of the invention is a device of the aforementioned To create a way that a more damage free demolding of especially thin-walled gloves made of elastomeric material from a form simplified.

Diese Aufgabe wird erfindungsgemäß durch die im kennzeichenden Teil des Patentanspruches 1 enthaltenen Merkmale gelöst.This object is achieved by the in the characterizing part of claim 1 contained features solved.

Durch die erfindungsgemäßen Maßnahmen wird durch bloße Ausbildung von Vertiefungen an der Form, die den Formgebungsprozeß in keiner Weise beeinträchtigen, erreicht, daß unter Wegfall von zusätzlichen Düsen die Greifmittel ohne Gefahr einer Beschädigung des hergestellten Handschuhs in Anlage an den zu entformenden Handschuh gelangen und dadurch der Handschuh in einfacher Weise von der Form abgezogen werden kann.Through the measures according to the invention, mere training of Wells on the shape that do the molding process in no way affect that achieved with the elimination of additional nozzles Gripping agent without risk of damage to the glove produced come into contact with the glove to be removed and thereby the Glove can be easily removed from the mold.

Zwar ist es bekannt (US-PS 32 68 647), auf einer Form zur Herstellung von Handschuhen aus elastomerem Material langgestreckte Vertiefungen anzubringen. Jedoch werden dort eine große Anzahl von engständig ange­ ordneten Aussparungen über dem Umfang der Form verwendet, um die Umfangs­ fläche des Schaftbereichs des Handschuhs zu vergrößern und damit nach dem Trocknen des elastomeren Materials im Schaftbereich des Handschuhs eine größere Dicke zu erreichen. Bei derartigen dickwandigen Hand­ schuhen stellt aber ein beschädigungsfreies Entformen kein Problem dar.Although it is known (US Pat. No. 3,268,647), on a mold for manufacture elongated recesses of gloves made of elastomeric material to attach. However, a large number of them are advertised there closely arranged recesses over the perimeter of the shape used to the perimeter area of the shaft area of the glove to enlarge drying of the elastomeric material in the shaft area of the glove to achieve a greater thickness. With such a thick-walled hand shoes, however, damage-free demoulding is not a problem.

Zweckmäßige Weiterbildungen der Erfindung sind durch die in den Unter­ ansprüchen enthaltenen Merkmale gekennzeichnet.Advantageous developments of the invention are those in the sub features contained claims marked.

Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung beschrieben. Darin zeigtAn embodiment of the invention is described below with reference to FIG Drawing described. In it shows

Fig. 1 eine Ansicht einer Ausführungsform einer Form, Fig. 1 is a view of an embodiment of a mold,

Fig. 2 eine Ansicht dieser Form, jedoch um 90° gedreht, wobei ein Teil längs der Linie II-II in Fig. 1 geschnitten ist, sowie Fig. 2 is a view of this shape, but rotated by 90 °, a part being cut along the line II-II in Fig. 1, and

Fig. 3 eine Schnittansicht längs der Linie III-III von Fig. 1. Fig. 3 is a sectional view taken along the line III-III of Fig. 1,.

Im dargestellten Ausführungsbeispiel ist die Form 1 zur Herstellung von Handschuhen aus einem Elastomer bestimmt. Die Form ist aus Por­ zellan und rund, insbesondere kreisrund im Querschnitt. Die Form weist im Greifbereich, wo der geformte Handschuh bei der Entformung durch Umwenden und Abziehen gefaßt wird, zwei Vertiefungen a, a₁, die diametral gegenüberliegend angeordnet und damit praktisch auf jeder Seite der Form angeordnet sind. Bei der dargestellten Ausfüh­ rungsform sind diese Vertiefungen langgestreckt.In the illustrated embodiment, shape 1 is intended for the production of gloves made of an elastomer. The shape is porcelain and round, especially circular in cross-section. The shape has two recesses a, a ₁ in the gripping area, where the shaped glove is grasped during removal from the mold by turning and peeling, which are arranged diametrically opposite one another and are thus arranged practically on each side of the shape. In the illustrated embodiment, these depressions are elongated.

Diese Ausbildungen haben zur Folge, daß der Elastomer b, wovon der Handschuh gebildet ist, nach seinem Schwinden bzw. Schrumpfen auf den Vertiefungen a, a₁ entsprechend Fig. 2 gespannt ist. Die Breite und Tiefe der Vertiefungen sind derart gewählt, daß unmittelbar und ohne irgendeine Schwierigkeit zwischen Form und Handschuh Greifmittel ein­ geführt werden können, die schematisch mit c bezeichnet sind und zum Abziehen des Handschuhs zum Zwecke seiner Entformung verwendet wer­ den. Es ist somit nicht mehr erforderlich, auf Mittel zurückzugreifen, die dazu bestimmt sind, den Handschuh zum Zwecke des Greifens her­ zurichten, woraus eine beträchtliche Wirtschaftlichkeit mit Hinsicht auf Material und Zeit resultiert, da selbst manuell das Greifen des Handschuhs einfach und schnell vorgenommen werden kann.These designs have the consequence that the elastomer b , of which the glove is formed, is stretched after its shrinkage or shrinkage on the recesses a, a ₁ corresponding to FIG. 2. The width and depth of the depressions are chosen such that a gripping means can be introduced directly and without any difficulty between the shape and the glove, which are indicated schematically by c and used to remove the glove for the purpose of its demolding. It is therefore no longer necessary to use means which are designed to prepare the glove for the purpose of gripping, which results in considerable economy in terms of material and time, since even the gripping of the glove can be carried out easily and quickly by hand .

Die Ränder d der Vertiefungen sind nicht in einem scharfen Winkel, sondern abgerundet ausgebildet, so daß auf dem hergestellten Hand­ schuh kein Abdruck verbleibt. Die Abmessungen der Vertiefungen sind abhängig von dem herzustellenden Gegenstand und den für seine Ent­ fernung verwendeten Mittel gewählt.The edges d of the wells are not formed at a sharp angle, but rounded, so that no shoe remains on the hand made. The dimensions of the wells are selected depending on the object to be manufactured and the means used for its removal.
