Definitions
- the invention relates to a device for the strand-like discharge of pasty masses contained in deformable tubular bags, with a cylinder which can be loaded with a tubular bag, the end face of which, in the discharge direction, has a central opening or outlet opening aligned with the spout connection of the tubular bag, one axially in the cylinder against the Tubular bag displaceable, essentially piston-shaped pressure piece and a device for axial displacement of the pressure piece.
- British patent applications 2 088 998 and 2 090 336 relate to discharge devices for tubular bags.
- the problem of pinching the bag is already known from them (cf. GB-A 2 090 336, page 2, lines 8 to 21). It is proposed there to remedy this problem by designing the piston face side in a particularly profiled manner (cf. GB-A 2 090 336, page 2, lines 21 to 25 and FIGS. 3 to 5 and GB-A 2 088 998, 3 and 3a).
- this does not prevent the aforementioned after-running of the pasty mass.
- the invention has for its object to improve a device of the type described in such a way that you can work with it without accepting the aforementioned uncontrolled leakage of tubular bag contents and at the same time prevent the bag film from being pinched.
- the pressure piece has a pressure relief spring which is supported on the cylinder wall and cooperates with it.
- This spring causes the pressure piece after its pressure relief, i.e. at the end or during an interruption of the discharge process, it does not remain in the respective working position, but is moved back by an amount dependent on the spring travel, as a result of which the contents of the tubular pouch are also depressurized and the mass has no reason to leave uncontrolled.
- the free end of the pressure relief spring can be moved along the inner wall of the cylinder with friction.
- the pressure relief spring which could also be called a "return spring” because of the effect it exerts on the pressure piece after completion or during an interruption of the discharge process, prevents the tubular bag from pinching the pressure bag between the pressure piece and the cylinder inner wall without problems .
- the pressure relief spring is preferably flat and designed so that it can be brought into contact with the piston-side end of the tubular bag.
- the pressure relief spring can be strip-shaped or star-shaped.
- the pressure piece has on its side facing the tubular bag a spring washer provided with radial lobes delimited by radial slots, the outer diameter of which is greater than the inner diameter of the cylinder before the pressure piece is inserted into the cylinder, with the result that the spring lobes follow support the insertion of the pressure piece against the inner wall of the cylinder.
- the length of the spring or the outer diameter of the aforementioned spring washer is preferably 8-12% larger than the inner diameter of the cylinder.
- the edge areas of the spring washer are preferably directed away from the pressure piece, that is, they run in the direction of the tubular bag.
- the pressure piece can be concave on its side pointing in the discharge direction, ie towards the tubular bag.
- the radius of the cavity thus formed is preferably smaller than the radius of the spring which is clamped but is not loaded in the pressure direction.
- the pressure relief spring can preferably be lifted off the pressure piece at least in the area of its spring tabs and is screwed to the pressure piece preferably via a central, axially extending screw, preferably with the interposition of a washer. It can be made of a resilient plastic, preferably polyethylene.
- a spring-elastic plastic offers the advantage that it causes only minimal frictional forces, so that it is always possible to work with a contact pressure which essentially corresponds to the working pressure.
- an elastic seal can be provided to seal the pressure piece against the inner wall of the cylinder, the outer diameter of which is preferably larger than the inner diameter of the cylinder before insertion into the cylinder.
- this seal is designed as a sleeve seal and is arranged on the end face of the pressure piece facing away from the tubular bag.
- the pressure piece which is preferably made of plastic, can have one or more circumferential grooves. This makes the pressure piece lighter and easier to move.
- an elastic sealing ring acting radially against the inner wall of the cylinder is arranged in such a groove, in particular in the central region. If a pneumatically operating device is provided for the axial displacement of the pressure piece, this sealing ring can have a sealing lip that can be expanded under the action of compressed air, so that the pressure piece can be inserted into the cylinder without any problems and yet an optimal all-round seal is ensured during the working process.
- the sealing ring is preferably designed as a profile ring, which has a small contact area with the inner wall of the cylinder, which contact surface is essentially independent of the pressurized air, thereby keeping the friction small.
- the pressure diameter of the pressure piece can be substantially matched to the inside diameter of the cylinder. Tilting of the pressure piece within the cylinder can be prevented with particular advantage by guide cams provided in the pressure piece, which are evenly distributed in at least one, preferably two levels around the pressure piece circumference and ensure safe and low-friction guidance of the pressure piece within the cylinder.
- the two levels are preferably provided on both sides of the sealing ring.
- the cylinder of the device according to the invention can have a cover, preferably screwable, with a central opening, which is detachably connected to it and merges into a discharge nozzle or nozzle that can be screwed onto the cover.
- this lid On its inside, this lid preferably has a flat contact surface for the tubular bag, in the center of which there is preferably a depression which serves to accommodate the edge of the cut-open bag and which preferably merges conically into the central opening or outlet opening.
- the flat contact surface offers the advantage that the tubular bag can be practically completely emptied under the action of the pressure piece acting on it.
- the aforementioned cover can have an outer, essentially cylindrical extension for screwing the discharge nozzle, this extension preferably having an external thread, in particular in such a way that conventional cartridge nozzles can be screwed to it.
- the outlet opening in the neck is preferably dimensioned in the inner diameter so that it essentially corresponds to the outlet opening of conventional cartridges. This enables the same conditions to be achieved as when processing cartridges.
- the above-mentioned lid is preferably formed in two parts, one lid part being formed by a union nut and the other lid part being formed by an extension piece which has the aforementioned flat contact surface for the tubular bag and preferably the depression which serves to accommodate the edge of the cut-open bag.
- a two-part cover design has the advantage that the cylinder is opened without rotating the attachment piece and, for example, if the color of the tubular bag is changed at any time, i.e. also before its final emptying, together with the attachment piece assigned to it in the cover and the discharge nozzle connected to it against another Tubular bag can be exchanged with another extension.
- the aforementioned extension is preferably dimensioned such that it can be inserted at least partially on the front side into the interior of the cylinder.
- a latching connection can be provided between the two cover parts, that is to say between the union nut and the extension piece, which prevents the two cover parts from unintentionally loosening from one another.
- the device shown in Fig. 1 is designed like a pistol. It has a handle 1 and a cylinder 2 carried by it.
- the cylinder 2 is provided with a screw cap 3 at its end shown on the left in the drawing and with a bottom 4 at its other end.
- the screw cap 3 has a central opening which merges into a discharge spout or nozzle 5.
- the cylinder 2 can have a pasty mass containing tubular bag 6 are loaded.
- a pressure piece 7 is tightly guided, which can be pressurized with compressed air from the side facing away from the screw cap 3, which can be supplied to the cylinder 2 via a line 8.
- This line 8 connects an adjustable compressed air valve 10, which is arranged in the handle 1 and can be actuated via a lever 9, to the bottom 4 of the cylinder 2.
- a compressed air line 11 leading into the bottom of the handle 1 leads to the compressed air valve 10 Relieves excess pressure in the cylinder if the compressed air supply is interrupted.
- the end of the essentially piston-shaped pressure piece 7 facing the screw cap 3 is concave and, with the interposition of a washer 12, is screwed to a spring washer 13 made of an elastic plastic via a central screw 14.
- the spring washer 13 (see FIG. 3) is circular in plan view and is provided with twelve radially extending slots 15 which subdivide its edge region into twelve radially extending spring tabs 16.
- the diameter of the spring washer 13 after screwing it to the pressure piece 7 is approximately 10% larger than the inside diameter of the cylinder 2.
- the end of the pressure piece 7 facing away from the screw cap 3 is provided with an elastic, preferably resilient sleeve seal 17, the outer diameter of which before insertion into the cylinder 2 is larger than its inner diameter, so that it ensures tight guidance of the pressure piece 7 in the cylinder 2.
- the spring tabs 16 are compressed somewhat and pressed into the cavity of the pressure piece 7 (cf. FIG. 4). After the discharge process has ended, they are supported against the inner wall of the cylinder 2 and also against the folded and consolidated outer region 117 of the tubular bag and press the pressure piece 7, which is no longer pressurized with air, by the amount s in the direction of the bottom 4 of the cylinder 2 ( see Fig. 5). The latter has the result that the content of the tubular bag 6 is no longer under pressure and therefore no longer has any reason to exit via the spout 5.
- the pressure piece 7, partially cut in FIG. 6, also carries a spring washer 13 with radially extending slots 15 on its front side pointing to the left in the drawing and spring tabs 16 running radially between them.
- the pressure piece 7 'shown in FIG. 6 is somewhat in diameter smaller than the pressure piece 7 shown in FIG. 2. In contrast to this, it has no cylindrical outer surface. Rather, it is provided with two grooves 19, 20 running all around and four guide cams 21 each on the outer edge of the two end faces.
- a profiled sealing ring 22 is arranged, which has a sealing lip 23 which can be expanded under the action of compressed air and has a narrow, circumferential sealing edge.
- the cover 24 shown in FIG. 7 has an extension 26 screwed to a discharge nozzle 25 and a union nut 27.
- the extension piece 26 has on its side facing away from the discharge nozzle 25 a flat tubular bag contact surface 28 and on the other side a two-stage extension 29 to which the discharge nozzle 25 is screwed.
- a depression 30 which serves to receive the edge of a cut-open bag, which is continued in a central opening in the projection 29 and thus communicates with the discharge nozzle 25.
