Definitions

• the present invention relates to a device for producing wire clips for securing bottle caps, in particular sparkling wine corks.
• EP-PS 0044798 describes a device in which four wire segments are fed to shaped steels which are movable towards a central mandrel and which form a wire star with the aid of mold surfaces lying at 45 ° to segments and quarter-circular recesses at the tip thereof is circular in the middle.
• the wire segments lie one above the other before forming a star, forming a square with protruding ends, and are forced as stops during shaping against profiled knives, so that the segments assume the profile of the mandrel circumference and the stops after the shaping process (page 3, line 9 -24).
• the double wires thus formed can diverge outwards after being formed.
• the present invention has for its object to provide a device by means of which the wire stars (wire bracket) can be produced mechanically easier and less prone to failure at a higher speed.
• the solution to this problem consists in a device for the production of wire brackets for securing bottle closures, in particular sparkling wine corks, in which four wires are guided to one another in such a way that two wire pairs cross each other at an angle of 90 ° and a mandrel is provided in the center is against which shaped steels can be moved parallel to the wire directions with the formation of double wires, the shaped steels having shaped surfaces arranged at an angle of 90 ° and at their tip facing the mandrel having quarter-circular recesses in which the shaped steels are lateral, to the shaped surfaces at an angle of 45 ° adjoining flanks on which the wires fed as endless wires rest before being cut to length and deformed, systems on the side flanks which are staggered in height being formed for the wires and associated with the shaped steels lying in front of these wire guides, which are combined with knives act as a nurse and pushers can be pushed onto the ends of the double wires formed by the shaped surfaces of the shaped steels.
• the device described above can be used to produce so-called wire baskets with four legs made of twisted double wires, the legs being bent around a locking wire loop and a sheet metal cover usually being inserted into the circular, then upper opening.
• the basket is e.g. put over a sparkling wine cork and twist the wire loop around the bottle neck, which ultimately secures the basket and the cork.
• the basket or its preform - the wire bracket - is made from four individual wire sections, for which the wire e.g. can initially be delivered via a straightening unit.
• the four wires are squared to each other (e.g. one over the other, whereby the conveying can be done with ball bushings. Then the wires, which protrude from the square equally long, are cut to twist the legs.
• the wire sections rest on the flanks of the shaped steels, whereby they can be supported from below.
• the wire sections first lay around the edges between the quarter-circular recesses and the shaped surfaces until they abut in pairs in the end position and form four central circular sections.
• the drillers are then pushed and rotated onto the parallel, outwardly projecting double wire ends in order to unite the double wires with one another.
• the shaped steels also have systems 15 which guide the wires one above the other in the desired manner, for which purpose they e.g. can be staggered in height or against each other.
• the contact surface can in principle also serve as a support for the wire sections which are secured by the recesses on the form steel mouths from falling. Magnetic wire bracing is also possible in principle.
• the drillers themselves have a front receptacle, which consists of a guide cone and the adjoining holding area.
• the holding region can have a rectangular or corresponding cross section, this being oriented such that the wires lie diagonally in the holder.
• a design of the drill in which the length of the receptacle, ie the wire holder itself, has a length that corresponds approximately to 5 to 6 times the wire diameter used has proven to be reliable.
• the drills are subject to above-average wear, which is why it is proposed to manufacture the receptacle and conical insertion area as a hard metal insert.
• the required movements of the device can be controlled by a single cam disk, which once moves the shaped steels towards the center and pushes the drills onto the wire ends via an offset curve and at the same time forms the drive for drilling, the Cam disc, for example has its own ring gear that rotates the drillers via their tines.
• Fig. 1 shows a top view of the device according to the invention in the diagram.
• Fig. 2 shows the contact of the wires on the contact surfaces of the shaped steels.
• Fig. 3 shows the form steels in the closed state.
• Fig. 4 shows driller and a section steel in section.
• Fig. 5 shows the grooving of the format steels.
• Fig. 1 Four wires 2,2 'and 3,3' are laid on top of each other in pairs to form a square with protruding ends, e.g. the wires 2,2 'lie on the wires 3,3'.
• the wires are brought into the position shown by a conveyor device (not shown) with ball bushings.
• the guides 1 and optionally an additional 13 are used for fixing, the latter cooperating with a knife 14 in order to produce the desired wire length.
• the mandrel 9 determines the diameter of the ultimately formed wire circle, which rests on top of the sparkling wine cork. With 8 the rails on which the shaped steels are guided.
• Fig. 2 shows that the wires 2,2 'rest on the flanks 4 and are limited in the vertical by systems 15, the selection of the height grading of the systems 15, the wires can also be intertwined in such a way that the drills all one can have the same direction of rotation without having to make idle revolutions.
• 3 shows the shaped steels 5 in the closed state around the mandrel 9, whereby double wires 10 with wire ends 12 protruding beyond the shaped steels 5 have formed on the shaped surfaces.
• the wires are shown here side by side, but preferably they lie one above the other in grooves (FIG. 5) in such a way that a necessarily tight wire layer is created and the shaped steels 5 are largely closed.
• the driller 11 is pushed over the wire ends 12, the direction of movement of which is indicated by an arrow. Four full revolutions of the driller are preferred.
• Fig. 4 shows a section through Fig. 3, wherein a Dril ler 11 with Driller drive 19 is shown on the left.
• the drill At its end facing the double wire end 12, the drill has a hard metal insert 17 with a rectangular cross section, in which the double wire end 12 is held diagonally.
• the insert is expanded conically 18 toward the mandrel 9, preferably at an angle of 60 °.
• a form steel 5 rests on the mandrel 9 and forms a wire in a quarter circle, the wires e.g. 2, 3 lie on the molding surface 6 or in the grooves 16 thereof.
