Description

Nach dem Patent 849 788 werden Drähte, Stangen oder Rohre beliebigen Materials, insbesondere in Metallspritzpistolen, vorwärts bewegt, indem diese durch eine Schwingspule und einen auf dieser beweglich' angeordneten Anker geführt werden, der im Rhythmus der Stromimpulse in Schwingung versetzt wird und mittels mit dem Anker verbundener und nur in einer Richtung den Draht transportierender Greifervorrichtungen den Draht od. dgl. vorschiebt.According to the 849,788 patent, any wire, rod, or tube can be used Materials, particularly in metal spray guns, are moved forward by passing them through a voice coil and an armature movably arranged on it are guided, which is set into oscillation in the rhythm of the current impulses and by means of the Anchor connected gripper devices that transport the wire only in one direction the wire or the like. Advances.

Zwecks Erhöhung der D.urohzugs.kraft und Vermeidung unwirksamen magnetischen KraftlinienfIusseü arbeiten zwei Schwingspülen zusammen auf ein Ankersystem mit Greifern derart, daß eine Schwingspule mit' Phasenverschiebung auf das Ankersystem wirkt. Dadurch werden die Anker nicht nur in einer Richtung angezogen und durch Federn wieder zurückgenommen, sondern von zwei Schwingspulen durch die Phasenverschiebung wechselweise angezogen. Die -in der Mitte befindliche Feder dient nunmehr lediglich als Führung der Greifer mit den beiden Ankern und zur Erzeugung einer Eigenschwingung, die es gestattet, das Ankersystem mit Greifern miit der Frequenz in Resonanz zu bringen. Die Eigenschwingung des Ankersystems .ist dann abhängig von der Masse und der = requenz.In order to increase the D.urohzugs.kraft and avoid ineffective magnetic Two oscillating sinks work together on an anchor system Grippers in such a way that a voice coil with 'phase shift on the armature system works. As a result, the anchors are not only tightened in one direction and through Springs taken back again, but from two voice coils due to the phase shift alternately attracted. The spring located in the middle is now only used to guide the gripper with the two anchors and to generate a natural oscillation, which allows the anchor system with grippers to resonate with the frequency bring. The natural oscillation of the anchor system is then dependent on the mass and der = frequency.

Zwei Schwingspulen i und 7 (Abb. i) sind durch Befestigungen 2 verbunden. Zwischen den Polen der Schwingspulen i und 7 befinden =sich die Anker 3 und 5, die durch die Greifer 6 miteinander verbunden .sind. Sie bilden zusammen mit der Feder 4 das Ankersystem, welches zwischen den Polen der Schwingspulen i und 7 schwingen kann und durch die Feder 4 zur Eigenschwingung gebracht wird.Two voice coils i and 7 (Fig. I) are connected by fasteners 2. Between the poles of the voice coils i and 7 are the armatures 3 and 5, the are connected to one another by the grippers 6. They form together with the spring 4 the armature system which oscillates between the poles of the voice coils i and 7 can and is brought to natural oscillation by the spring 4.

Ahb. 2 zeigt die Einzelheiten des Greifens 6 im Schnitt. Zwecks Verringerung des Schlupfes be-Milden sich iin dem Gehäuse 8 des Greifers sternförmig angeordnete Rollen, Kugeln oder Spannbacken, die sich in zur Mitte konisch verlaufenden Bohrungen io befinden und durch Federn i i gegen das zu transportierende Material 12 andrücken. Diese Anordnung gestattet den Transport des. Materials vermöge der klemmenden Eigenschaft der Kugeln, Rollen oder Spannbacken 9 nur in einer Richtung schlupflos.Ahb. 2 shows the details of the gripper 6 in section. In order to reduce of the slip are in a star-shaped arrangement in the housing 8 of the gripper Rollers, balls or clamping jaws, which are located in holes tapering towards the center io are located and press against the material 12 to be transported by springs i i. This arrangement allows the material to be transported by virtue of the clamping property the balls, rollers or jaws 9 slip-free only in one direction.

Claims

PATENT CLAIMS: i. Method of advancing wires, rods or pipes of any material, especially in metal spray guns, according to patent 849 788, characterized in that the movement executing part of the Device two voice coils act, of which one voice coil is only then used Effect comes when the other has just tightened the anchor system, and that material to be moved in one direction by being pressed against the material by means of springs Balls, rollers or clamping jaws is locked.

2. The method according to claim i, characterized characterized in that to achieve mutual operation of the two voice coils one of the two works with a phase shift.

3. Device for implementation of the method according to claims i and 2, characterized .by two on one anchor system Acting vibrating coils and grippers connected to the anchor system, which are made of balls. Rollers or clamping jaws and springs, which these balls, rollers or clamping jaws press against the material to be moved.

4. Apparatus according to claim 3, characterized in that the gripper has channels running conically to one another, in which there are balls or rollers that are attached to the only one by means of springs In the direction of transportable material.
