Abstract

An apparatus for producing chamber gloves has two glove moulds, the larger one of which is made that much larger than the smaller one by the dimension of the desired wall cavity and which are arranged spaced apart from each other at the fingertips by the dimension of the desired wall cavity, otherwise lying opposite each other. Such an apparatus is immersed with its glove moulds into a bath of a known type until the distance between the fingertips corresponding to the wall cavity is completely filled; after that, a stabilisation of the coatings deposited on the glove moulds is carried out, then the outer glove, formed on the larger glove mould, is drawn off the latter and slipped over the inner glove, formed on the smaller glove mould. Finally, the chamber glove thus formed is drawn off the smaller glove mould.

Description

Method and device for manufacturing

of chamber gloves, as well as chamber glove the The invention relates to a method and a device for the production of chamber gloves, as well as a chamber glove.

The purpose of a chamber glove is that it is special safe hand protection for manipulations in glove boxes can be used. Be like that in the German Offenlegungsschrift DE-OS 30 o5 113 A1 the disadvantages and even Gefada ren of the previously used single glove in glove boxes, in particular in the manipulation of radioactive substances.

In contrast, a chamber glove is not just a double one Single glove with correspondingly double security, but also points beyond even more advantages; so can the wall space of the glove ventilated or acted upon or flooded with any other medium will. This is also described in DE-30 05 113 A1 already mentioned; in particular is already described there e.g. on pages 8 and 9, which is a pure duplication The application advantages of such a rammer glove go beyond the simple wall of the glove owns. Such a chamber glove can only be a very thick single glove do not replace. Because a thick glove is difficult to handle and numb; In addition, the glove wall cannot constantly regenerate as with the «ammer glove e.g. also be cooled or heated.

In the case of the DE-OS 30 o5 113 A1 already mentioned, see there in particular Figure 1, as well as page 18 above of the description, known chamber glove consists consists of an outer and an inner wall that are firmly attached to one another in the fingertip area are connected. It is not disclosed there how such a glove can be manufactured at all is. It would be obvious to produce such a chamber glove simply by the first step is to use the fingertips of a smaller glove glued together with those of a larger, corresponding glove, to then in to put the larger glove over the smaller one in a second step.

But such adhesive connections are in the glove materials used up to now less permanent and also weaken the rest of the surrounding area of the Glove material. In addition, especially in the field of nuclear chemistry, the special requirements in most cases the use of the elastomer butyl skin protection or halogenated butyl-elautschuk for the manufacture of the gloves. The gloves themselves can only be used in talcated condition. But it is now known that neither vulcanized butyl rubber nor vulcanized halogenized butyl rubber can be permanently connected to one another, in particular glued. So failed so far the proposal of the chamber glove in decisive areas of application, where the need is absolutely necessary for security reasons. Furthermore, in the DE-OS 30 o 113 A1 proposed a chamber glove that is open on the wrist has annular ends which on the glove bax at different from each other Places to be determined gas-tight. This is intended to be an annular in the If necessary (for flooding), access to the wall space can be divided be created.

However, this requires a specially designed glove box, such as it is described in DE-OS 30 o5 113 A1. So it says there on page 19 above that the glove in the area of an approximately central, unspecified Ring flange in the glove lock 28 is set gas-tight so that a Inner chamber 4o is separated from an outer chamber 42; this is shown in FIG. 2 there.

In the area of the flow connections 36, 38 there is clearly on the Inside the wall of the glove lock the special ring flange can be seen; it is there recognizably welded to the wall of this glove lock 28. Therefore the previously known chamber glove requires a radical redesign the well-known glove locks.

This means an additional effort, but it is also a quick one Dissemination of the actually excellent Doppelkanmer glove stands in the way.

The invention is based on the object of a permanently connected, in particular to create non-glued kSmmer glove; this includes both a method for its production as well as the device suitable for it. Further such a chamber glove is to be created, which can be inserted into the existing glove boxes, here the conventional glove locks, used without any special effort can be.

This object is achieved in that according to the known and the proven principle of the immersion process is used. In this immersion process So far, a glove shape has been used to manufacture an ordinary Sinfach edge shoe immersed in a bath; the bath consisted of solutions, dispersions or plastisols different elastomers, also made of elastomers. Had the glove shape with covered a sufficiently thick covering from the bath, so the glove shape was made lifted out of the bath and the covering stabilized by a suitable process. Depending on the bath component used, the stabilization was e.g.

through vulcanization, cross-linking or hardening through frozen.

In the device according to the invention are two glove shapes, their larger by the dimension of the desired wall interspace correspondingly larger is designed as the smaller, at the fingertips of each other by the dimension dæ ewünscht.g wall thickness spaced apart, otherwise arranged opposite one another. which Significance of the spacing rules of the glove shapes and the fingertips from each other have, is based on the manufacturing method according to the invention in detail to be discribed.

In a preferred embodiment, at least one of the glove shapes is arranged on the wrist on a bar on a rotating organ, by virtue of which the Distance between the glove shapes can be varied.

This makes it possible to set different wall gaps, and to simplify the production of the chamber glove, as can be seen from the manufacturing method according to the invention will be shown on.

In order to be able to manufacture a 'K: ammer edge shoe without any special Changes to the known glove locks that can be used are those on the wrist Ends of the glove shapes as flange parts in the larger glove shape towards the inside and molded to the outside in the case of the smaller glove shape. The flange parts of the two Glove shapes are the dimensions of the desired wall gap with respect to one another dimensioned accordingly differently. This gives the finished double-chambered glove wrist-side in - Kwnrner flange connection end.

In order to finally be able to manufacture a chamber glove, the one suitable connection for filling or flooding its wall space possesses, is in the device according to the invention on the flange part of the smaller one Glove shape molded a tube pin. This tube pin is on the flange part outwards.

Around the wall gap in its spacing between the inner one To stabilize the glove and the outer glove, elevations of the distance are used functional on the inner glove. For this purpose, a device according to the invention in a preferred embodiment form a smaller glove shape, which is used to form such spacing bumps is profiled.

According to the invention, one of the aforementioned n devices according to the invention is used used according to the following procedure: The device is with its glove shapes immersed in a known type of bath; the glove shapes occupy themselves with the Medium of the bath. This happens until the one corresponding to the wall gap The distance between the fingertips is completely filled; since the two glove shapes are in their other areas are usually spaced further apart form exclusively One-piece bridges made from the medium of the bath between the fingertips. Thereupon the deposits deposited on the glove molds are stabilized; at the same time the areas filled between the fingertips are also stabilized.

Then the outer glove formed on the larger glove shape becomes peeled off from this and over the inner one formed on the smaller glove shape Glove put on; this can be brought about or at least facilitated that if necessary the at least one of the glove shapes, the wrist-side is arranged on a rotary organ on the bar, the other glove shape is folded away. If necessary, the hose connector formed on the hose pin is also used turned out. Eventually the chamber glove formed in this way becomes the smaller one Glove shape peeled off.

Several dives are possible for special requirements or applications be performed. Different baths can be used; achieved In this way, it is not just a collection glove with thick walls but also e.g. a soft inside and one made of a different material existing harder outside of the chamber glove.

The chamber glove produced according to the invention can be used in anyone Identify the case properly, i.e. from just one at your fingertips distinguish glued glove. This stems from the fact that in the invention tammer glove, the connections between the fingertips in one piece material identical to the rest of the glove area are formed. The stabilization process is used in the implementation of the method according to the invention of the glove material equally from the respective covering surface to the Glove shapes advanced into the material interior; this can be done with a cross-sectional analysis can be easily detected. Of course, things are different if they are only glued together Gloves.

In the case of the chamber glove according to the invention, an embodiment is preferred in which the outer glove and the inner glove each have one on the wrist have outwardly molded flange.

The chamber glove can be closed at these flanges; this can be done, for example, by means of a suitable flanæch ring on the glove box, as will be described in detail later. But the flanges can also follow Filling the space between the walls, e.g. glued. In particular for flooding with fluid media, the outer glove has in the area of its Flange on a hose connector directed towards its inside. This hose connector then serves as a supply resp.

Discharge line for the through the wall gap to be passed fluid medium.

The one that matches the chamber glove according to the invention with flanges The mounting flange is a special slip-on flange ring. It consists of one Flange outer ring and a flange inner ring, with holes in the flange outer ring are arranged for screws, as is known from ordinary flange rings, but the flange inner ring is only flush with the flange outer ring on one side is, on the other hand, less than flush, and having flange holes for the hose connector of the chamber glove. are introduced into the inner flange ring.

This will be better later in the explanation of FIG. 2 in detail be described and understandable.

Thus, a chamber glove is created that is permanently connected is. In its preferred embodiment, the Xammer-Hands according to the invention can [huh used in the conventional glove locks of the well-known hose boxes will; this will be described with reference to one of the following figures. Finally the method according to the invention and the associated device do not mean anything Retrofitting of a manufacturing plant for the previously known single gloves. The usual bath and the entire conventional immersion device can continue to be used will. Only the device according to the invention has to be re-used. The diving principle itself is also used unchanged in the method according to the invention.

An embodiment of the invention is shown in the drawings, which are described in more detail below. They show: FIG. 1 the cross section through a device according to the invention in a conventional bathroom; Figure 2 shows the cross section a double-chamber glove according to the invention, as it is in a conventional glove lock is flanged in.

The bar is marked with the reference number 1, on which in each case with rotating members 2, the glove molds 3, 5 are arranged. The rotating members 2 are in particular 80 designed that the glove molds 3, 5 folded away from each other can be; in the example shown, this is to be thought of as at least an axis of rotation of the rotating members 2 is perpendicular to the plane of the drawing. Clearly visible as well as both the larger glove shape 3 and the smaller glove shape 5 die Show the shape of a slightly open hand. Both glove shapes 3.5 come together near the fingertips 8; this also applies to the tips of the thumbs 12. On the wrist side, both glove shapes 3, 5 are molded in the flange parts 4. The flange parts have a plane that is perpendicular to the longitudinal direction of the glove shapes 3, 5 lies. Both the flange parts 4 and the distance between the fingertips 8 or thumb 12 corresponds to the dimension of the desired wall gap 7. The two glove forms 3, 5 are in a bath 13 of a known type in a dip bath 9. The bar 1 is held by the tanch mechanism 11 on the diving device lo. That too device 1o takes care of the immersion mechanism 11 for the necessary movements; so the bar 1 with the invention Device can be rotated and raised, possibly also in a not shown another bath to be driven.

A coating separates from the bath 13 on the glove molds 3, 5 from that of the growing together between the gloves to be formed in the area the fingertips 8 or thumb tips 12 also ensures. Then the glove shapes 3, 5 lifted out of the strip 13 on the bar 1 and carried out the stabilization. Thereafter, the outer glove 31 formed on the larger glove shape 3 is pulled off, which can happen in particular that the larger glove shape 3 around the Rotary member 2 is folded away from the smaller glove shape 5.

Then the peeled off outer glove 31 is put over the inner glove 51 placed on the smaller glove shape 5 and the one formed on the tubular pin 6 Hose connector 61 turned out. The already finished one. Chamber glove must can then only be pulled off the smaller glove shape 5.

A finished chamber glove is shown in cross section in FIG. The areas on the fingertips 8 are identified by the reference numeral 71 in FIG which the outer glove 31 and the inner glove 51 are integral with each other are connected. Otherwise, the outer glove is 31 and the inner glove 51 spaced apart from one another by the wall gap 7. Pictured here is the , Yammer glove as it extends into a box interior 14; this is in in practice often caused by the fact that in the box interior 14 compared to the exterior 2o there is a negative pressure. The flanges 41 are between the Box inner wall 15 and a mounting flange clamped. This mounting flange is identified by the reference numerals 16 and 17 in this figure. In cross section it is made up of the inner flange ring 16 and the outer flange ring 17, which are only apparently separated from one another by the flange holes 18. In reality the han flange ring is a one-piece that on its The circumference of flange bores 18 is penetrated, which acts as a passage for the hose nozzle 61 serve.

The flange inner ring 16 is flush on the outside with the flange outer ring 17, but not on the inside; there it leaves a space for the flange parts 4 of gloves 31.51. As a result, the flange 41 becomes the open one in this area Wall gap 7 received. The flange 41 is further outward from the flange outer ring 17 pressed firmly and tightly against the box inner wall 15. This is for the sake of clarity a screw 19 shown that the flange outer ring 17 against the box inner wall 15 presses, in which it is screwed into the inner wall of the box in a known manner. It is thus clear that the chamber glove according to the invention can be found in a conventional glove lock can be used. The only constructive variation that became necessary is to use a new flange.

As shown, the flange ring is one with a one-sided flatter inner flange ring 16 and a normal flange ring 17, however, special flange bores 18 are provided in the flange inner ring are.

In this disclosure, the term "hammer glove" means one double-walled glove, in particular a glove that consists of an outer and inner glove is made, with or so that between the glove walls chamber-like space is present.
