GEBIET DER ERFINDUNGFIELD OF THE INVENTION

Die vorliegende Erfindung betrifft ein Setzgerät gemäß dem Oberbegriff des Anspruchs 1 zum Setzen von Befestigungsmitteln, wie Nägeln, Nieten, Stiften, Ankern, Klammern oder anderen, vorzugsweise stiftförmigen, Befestigungselementen. Ferner betrifft die Erfindung ein Steuerungsverfahren gemäß dem Oberbegriff des Anspruchs 9 für ein Setzgerät.The present invention relates to a setting tool according to the preamble of claim 1 for setting fasteners, such as nails, rivets, pins, anchors, brackets or other, preferably pin-shaped, fasteners. Furthermore, the invention relates to a control method according to the preamble of claim 9 for a setting tool.

Ein derartiges Setzgerät und ein derartiges Verfahren sind aus dem Dokument US 2007/0045377 A bekannt.Such a setting device and such a method are from the document US 2007/0045377 A known.

OFFENBARUNG DER ERFINDUNGDISCLOSURE OF THE INVENTION

Das erfindungsgemäße Setzgerät hat einen Stößel, der angetrieben durch Druckluft das Befestigungselement eintreibt. Eine Pumpeinrichtung erzeugt die Druckluft. Die Pumpeinrichtung hat einen Pumpzylinder, eine Pumpkolben und eine ringförmige Magnetanordnung um den Pumpzylinder. Der Pumpkolben ist in dem Pumpzylinder längs einer Achse beweglich. Ein axialer Verschluss des Pumpzylinders schließt mit dem Pumpkolben ein Pumpvolumen innerhalb des Pumpzylinders ab. Die ringförmige Magnetanordnung hat eine Magnetspule, die den Pumpzylinder umschließt und die längs der Achse wenigstens teilweise mit dem magnetisierbaren Verschluss und teilweise mit dem magnetisierbaren Pumpkolben überlappt.The setting tool according to the invention has a plunger, driven by compressed air drives the fastener. A pumping device generates the compressed air. The pumping device has a pumping cylinder, a pumping piston and an annular magnet arrangement around the pumping cylinder. The pump piston is movable in the pump cylinder along an axis. An axial closure of the pump cylinder with the pump piston completes a pumping volume within the pump cylinder. The annular magnet assembly has a solenoid which encloses the pump cylinder and which at least partially overlaps along the axis with the magnetizable shutter and partially with the magnetizable pump piston.

Der durch den Verschluss halbseitige geschlossene Pumpzylinder bildet zusammen mit dem Pumpkolben eine linear Kolbenhubpumpe. Der Antrieb der Kolbenhubpumpe erfolgt durch die Magnetspule, welche den magnetisierbaren Pumpkolben in die Mitte der Magnetspule ziehen und dabei die Luft in dem Pumpvolumen komprimieren kann.The half-sided closed pump cylinder, together with the pump piston, forms a linear piston stroke pump. The drive of the piston stroke pump takes place through the magnet coil, which can pull the magnetizable pump piston into the middle of the magnet coil and thereby compress the air in the pump volume.

Die Anordnung des Verschlusses innerhalb der Magnetanordnung, vorzugsweise innerhalb der Magnetspule, erweist sich als effizient für das Komprimieren der Luft. Die notwendige Kraft zum Komprimieren der Luft steigt etwa invers zu dem sich verringernden Abstand des Pumpkolbens zu dem Verschluss. Aufgrund der Anordnung des magnetisierbaren Verschlusses innerhalb der Magnetanordnung erhöht sich die von der Magnetspule auf den Pumpkolben ausgeübte Kraft ebenfalls etwa invers zu dem Abstand zwischen Verschluss und Pumpkolben. Die Energie kann von der Magnetspule auf die Volumenarbeit des Pumpvolumens über die gesamte Bewegung des Pumpkolbens optimal übertragen werden. Der Verschluss und der Pumpkolben sind vorzugsweise aus einem weich magnetischen Material gebildet. Sobald die Magnetspule nicht bestromt ist, sind Verschluss und Pumpkolben weitgehend unpolarisiert und werden durch umgebende Streufelder depolarisiert. Ohne die Magnetspule ziehen sich der Verschluss und der Pumpkolben nicht an.The placement of the closure within the magnet assembly, preferably within the magnet coil, proves to be efficient for compressing the air. The force needed to compress the air increases approximately inversely with the decreasing distance of the pump piston to the shutter. Due to the arrangement of the magnetizable closure within the magnet arrangement, the force exerted by the magnet coil on the pump piston force also increases approximately inversely to the distance between the closure and the pump piston. The energy can be optimally transferred from the solenoid coil to the volume work of the pumping volume over the entire movement of the pump piston. The closure and the pump piston are preferably formed of a soft magnetic material. As soon as the magnetic coil is de-energized, the shutter and the pump piston are largely unpolarized and are depolarized by surrounding stray fields. Without the solenoid, the shutter and the pump piston will not tighten.

Eine Ausgestaltung sieht vor, dass der Verschluss mit wenigstens 10 % der Magnetanordnung, vorzugsweise der Magnetspule, längs der Achse überlappt. Der Pumpkolben überlappt vorzugsweise in jeder Stellung für wenigstens 10 % mit der Magnetanordnung, vorzugsweise der Magnetspule, längs der Achse.An embodiment provides that the closure overlaps at least 10% of the magnet arrangement, preferably the magnet coil, along the axis. The pumping piston preferably overlaps in any position for at least 10% with the magnet assembly, preferably the solenoid, along the axis.

Eine Ausgestaltung sieht vor, dass eine Druckkammer, die die von der Pumpeinrichtung erzeugte Druckluft zwischenspeichert. Die Pumpeinrichtung treibt nicht unmittelbar den Stößel an. Ein Volumen der Druckkammer ist zur Aufnahme einer Luftmenge für einen Setzvorgang oder für weniger als fünf Setzvorgänge dimensioniert. Eine von dem Pumpvolumen aufgenommene Luftmenge ist vorteilhafterweise geringer als eine für den Setzvorgang vorgesehene Luftmenge. Der Pumpkolben benötigt mehrere Hübe, bis eine für den Setzvorgang benötigte Luftmenge bereitgestellt ist.An embodiment provides that a pressure chamber, which temporarily stores the compressed air generated by the pumping device. The pumping device does not directly drive the plunger. A volume of the pressure chamber is dimensioned for receiving an amount of air for a setting process or for less than five setting operations. An amount of air taken up by the pump volume is advantageously less than an air quantity intended for the setting process. The pump piston requires several strokes until a required amount of air for the setting process is provided.

Eine Ausgestaltung sieht vor, dass der Stößel starr mit einem Treibkolben verbunden ist, der Treibkolben innerhalb eines hohlen Führungszylinders ein Arbeitsvolumen abschließt und die Druckluft in das Arbeitsvolumen einspeisbar ist. Die von der Pumpeinrichtung erzeugte und in der Druckkammer zwischengehaltene Druckluft beschleunigt den Treibkolben in dem Führungszylinder. Der Stößel wird von dem Treibkolben mitgenommen und treibt den Nagel oder ein anderes Befestigungsmittel ein.An embodiment provides that the plunger is rigidly connected to a drive piston, the drive piston within a hollow guide cylinder completes a working volume and the compressed air can be fed into the working volume. The pressure generated by the pumping means and held in the pressure chamber compressed air accelerates the driving piston in the guide cylinder. The plunger is taken by the drive piston and drives the nail or other fasteners.

Ein Steuerungsverfahren für das Setzgerät hat die Schritte: Erzeugen von Druckluft, indem ein Strompuls in eine Magnetspule eingespeist wird und das erzeugte Magnetfeld einen magnetisierbaren Pumpkolben innerhalb der Magnetspule in einem Pumpzylinder bewegt, und Beschleunigen eines Stößels mit der Druckluft auf ein in Setzrichtung angeordnetes Befestigungselement. Das Setzgerät konvertiert elektrische Energie, in ein Magnetfeld, in eine Kompression von Luft und anschließend in kinetische Energie des Stößels. Die Konversion der Energie aus dem Magnetfeld in die Kompression ist durch den innerhalb der Magnetspule geführten Pumpkolben besonders effizient.A control method for the setting tool has the steps of: generating compressed air by feeding a current pulse into a solenoid and the generated magnetic field moves a magnetizable pumping piston within the solenoid in a pumping cylinder and accelerating a plunger with the compressed air to a fixing element arranged in the seating direction. The setting tool converts electrical energy, into a magnetic field, into a compression of air and then into kinetic energy of the ram. The conversion of the energy from the magnetic field into the compression is particularly efficient due to the pump piston guided inside the magnet coil.

Eine Ausgestaltung sieht vor, dass dass eine Druckkammer mit der Druckluft geladen wird und ansprechend auf ein Betätigen eines Bedienelements durch den Anwender der Stößel mit der Druckluft aus der Druckkammer beschleunigt wird. Das Laden der Druckkammer erfolgt, indem die Magnetspule mit einer Sequenz aus Strompulsen zum mehrfachen Hin-und Herbewegen des Pumpkolbens bestromt wird. Ein einziger Hub zum Bereitstellen der Luftmenge für den Setzvorgang hat den offensichtlichen Vorteil, dass die zusätzliche Druckkammer und ein Zwischenspeichern der Druckluft entfällt. Das Setzgerät wird leichter und hat weniger Verlustkanäle. Der mehrfache Hub erweist sich dennoch als effizienter, da die Pumpeinrichtung insbesondere bei einem kurzen Hub besonders effizient arbeitet und damit die Nachteile der zusätzlichen Druckkammer überkompensiert.An embodiment provides that a pressure chamber is charged with the compressed air and is accelerated in response to an actuation of an operating element by the user of the plunger with the compressed air from the pressure chamber. The pressure chamber is charged by energizing the solenoid with a sequence of current pulses for reciprocating the pump piston several times. A single stroke for providing the amount of air for the setting process has the obvious advantage that the additional pressure chamber and a buffering of the compressed air is eliminated. The setting tool becomes lighter and has less loss channels. Nevertheless, the multiple stroke proves to be more efficient, since the pumping device operates particularly efficiently, in particular with a short stroke, and thus overcompensates the disadvantages of the additional pressure chamber.

Eine Amplitude und/oder eine Dauer der Strompulse kann innerhalb einer Sequenz zunehmen. Die Pumpeinrichtung verrichtet mit zunehmender Luftmenge in der Druckkammer pro Hub mehr Volumenarbeit, insbesondere durch Erreichen eines höheren Drucks, um die Druckkammer weiter aufzuladen.An amplitude and / or duration of the current pulses may increase within a sequence. The pumping device performs more volume work per stroke with increasing amount of air in the pressure chamber per stroke, in particular by achieving a higher pressure in order to continue to charge the pressure chamber.

AUSFÜHRUNGSFORMEN DER ERFINDUNGEMBODIMENTS OF THE INVENTION

Fig. 1 zeigt ein beispielhaftes Setzgerät 1 für Nägel 2 oder ähnliche stiftförmige Befestigungselemente. Das Setzgerät 1 hat einen druckluft-getriebenen Stößel 3, der den Nagel 2 in ein Werkstück treibt. Die Druckluft für einen Setzvorgang wird in einer Druckkammer 4 vorgehalten. Eine Pumpeinrichtung 5 in dem Setzgerät 1 lädt die Druckkammer 4 mit einer für den Setzvorgang ausreichenden Luftmenge und auf das notwendige Druckniveau. Fig. 1 shows an exemplary setting tool 1 for nails 2 or similar pin-shaped fasteners. The setting tool 1 has a compressed air-driven plunger 3, which drives the nail 2 in a workpiece. The compressed air for a setting process is in a Held pressure chamber 4 . A pumping device 5 in the setting device 1 loads the pressure chamber 4 with a sufficient amount of air for the setting process and to the required pressure level.

Die für die Funktionalität wesentlichen Komponenten des Setzgeräts 1 sind innerhalb eines Gehäuses 6 angeordnet, insbesondere der Stößel 3, die Druckkammer 4 und die Pumpeinrichtung 5. Der Anwender kann das Setzgerät 1 mit einem Handgriff 7 führen und beim Setzen der Nägel 2 halten kann. Der Handgriff 7 ist unlösbar, starr oder mittels Dämpfungselementen, mit einem Gehäuse 6 des Setzgeräts 1 verbunden. Das Setzgerät 1 wird primär mit elektrischer Energie versorgt, beispielsweise durch ein Batteriepaket 8, welches unlösbar vorzugsweise lösbar an dem Handgriff 7 oder dem Gehäuse 6 vom Anwender befestigbar ist. Am oder nahe des Handgriffs 7 ist ein Triggerschalter 9, welcher bei Betätigung durch den Anwender einen Setzvorgang auslöst. Vorzugsweise ist neben dem Betätigen des Triggerschalters 9 noch ein Sicherheitsmechanismus, z.B. durch Anpressen des Setzgeräts an eine Wand, freizuschalten.The essential components for the functionality of the setting tool 1 are arranged within a housing 6 , in particular the plunger 3, the pressure chamber 4 and the pump means 5. The user can guide the setting tool 1 with a handle 7 and hold when setting the nails 2 . The handle 7 is inseparable, rigid or by means of damping elements, connected to a housing 6 of the setting device 1 . The setting device 1 is supplied primarily with electrical energy, for example by a battery pack 8, which is inextricably preferably detachably fastened to the handle 7 or the housing 6 by the user. At or near the handle 7 is a trigger switch 9, which triggers a setting operation when actuated by the user. Preferably, in addition to the actuation of the trigger switch 9 , a safety mechanism, for example, by pressing the setting device to a wall, unlock.

Der Stößel 3 hat einen Schlagkopf 10, der in seiner Form den verwendeten Nägeln 2 angepasst ist. Der Schlagkopf 10 hat typischerweise etwa den gleichen Durchmesser wie ein Kopf der Nägel 2. Der Schlagkopf 10 ist längs einer Arbeitsachse 11 innerhalb einer Nagelführung 12 geführt. Der Nagel 2 wird für den Setzvorgang in die im wesentlichen rohrförmige Nagelaufnahme 12 eingelegt. Das Einlegen kann manuell durch den Anwender, semiautomatisch oder automatisch durch eine Zuführung erfolgen. Der Schlagkopf 10 schlägt innerhalb der Nagelführung 12 auf den Nagel 2 und treibt den Nagel 2 in Setzrichtung 13, längs der Arbeitsachse 11 aus der Nagelführung 12 heraus, ggf. in ein Werkstück.The plunger 3 has a striking head 10, which is adapted in shape to the nails 2 used. The impact head 10 typically has about the same diameter as a head of the nails 2. The impact head 10 is guided along a working axis 11 within a nail guide 12 . The nail 2 is inserted for the setting process in the substantially tubular nail receptacle 12 . The insertion can be done manually by the user, semi-automatically or automatically by a feeder. The impact head 10 strikes within the nail guide 12 on the nail 2 and drives the nail 2 in the setting direction 13, along the working axis 11 of the nail guide 12 out, possibly in a workpiece.

Der Stößel 3 ist an seinem rückseitigen, dem Nagel-abgewandten Ende mit einem Treibkolben 14 versehen. Der Treibkolben 14 hat vorzugsweise einen wesentlich größeren Durchmesser als der Schlagkopf 10, um den Stößel 3 effizient mit der Druckluft anzutreiben.The plunger 3 is provided at its rear, the nail-remote end with a driving piston 14 . The drive piston 14 preferably has a substantially larger diameter than the impact head 10 to efficiently drive the plunger 3 with the compressed air.

Der Treibkolben 14 ist in einen halbseitig geschlossenen Führungszylinder 15 eingesetzt. Der Treibkolben 14 liegt umfänglich an der inneren Mantelfläche 16 des Führungszylinders 15 druckdicht an und wird von der Mantelfläche längs der Arbeitsachse 11 geführt. Ein dem Nagel 2 abgewandtes Ende des Führungszylinders 15 ist durch einen Boden 17 geschlossen. Der Treibkolben 14 schließt somit in Setzrichtung 13 innerhalb des Führungszylinders 15 ein pneumatisches Arbeitsvolumen 18 ab.The drive piston 14 is inserted into a guide cylinder 15 closed on one side. The drive piston 14 is circumferentially on the inner circumferential surface 16 of the guide cylinder 15 pressure-tight and is guided by the lateral surface along the working axis 11 . A nail 2 facing away from the end of the guide cylinder 15 is closed by a bottom 17 . The drive piston 14 thus closes in the setting direction 13 within the guide cylinder 15 from a pneumatic working volume 18 .

Die Druckkammer 4 ist über eine steuerbare Zuleitung 19 mit dem Arbeitsvolumen 18 verbunden. Die Zuleitung 19 erfolgt vorzugsweise über eine Öffnung in dem Boden 17. Die Zuleitung 19 beinhaltet ein schaltbares Ventil 20, welches ansprechend auf ein Betätigen des Triggerschalters 9 geöffnet wird.The pressure chamber 4 is connected via a controllable supply line 19 with the working volume 18 . The supply line 19 is preferably via an opening in the bottom 17. The supply line 19 includes a switchable valve 20 which is opened in response to an actuation of the trigger switch 9 .

Die Druckkammer 4 hat ein ausreichendes Volumen um eine Luftmenge für vorzugsweise genau einen Setzvorgang zu speichern. Das Volumen liegt beispielsweise im Bereich von 100 cm3 bis 300 cm3. Bei einer vollbeladenen Druckkammer 4 für einen Setzvorgang liegt der Druck zwischen 7 bar und 10 bar. Die Druckkammer 4 ist mit einem thermisch isolierenden Mantel 21 umgeben, der beispielsweise eine Wandung der Druckkammer 4 innen auskleidet oder auf die Außenfläche aufgebracht ist. Der Mantel 21 ist beispielsweise aus einem Kunststoff vorzugsweise aus einem geschäumten Kunststoff.The pressure chamber 4 has a sufficient volume to store an amount of air for preferably exactly one setting operation. The volume is, for example, in the range of 100 cm 3 to 300 cm 3 . In a fully loaded pressure chamber 4 for a setting process, the pressure is between 7 bar and 10 bar. The pressure chamber 4 is surrounded by a thermally insulating jacket 21 , which, for example, lining a wall of the pressure chamber 4 inside or is applied to the outer surface. The jacket 21 is made of a plastic, for example, preferably made of a foamed plastic.

Die Pumpeinrichtung 5 (Fig. 2) füllt die Druckkammer 4 mit Luft, bis die für den Setzvorgang notwendige Luftmenge und/oder der für den Setzvorgang notwendig Druck erreicht ist. Die Pumpeinrichtung 5 hat einen linear bewegten Pumpkolben 22. In der dargestellten Ausführungsform ist der Pumpkolben 22 längs der Arbeitsachse 11 geführt, der Pumpkolben 22 kann jedoch auch längs einer anderen Achse 11 geführt sein. Der Pumpkolben 22 läuft innerhalb eines hohlen Pumpzylinders 23. Der Querschnitt des Pumpkolbens 22 und der Innenquerschnitt des Pumpzylinders 23 sind passgenau, um einen druckdichten Verschluss zu gewährleisten. Dichtungsringe auf dem Pumpkolben 22 können Toleranzen in der Herstellung ausgleichen. Einer Stirnfläche 24 des Pumpkolbens 22 gegenüberliegend ist der Pumpzylinder 23 durch einen stationären Verschluss 25 verschlossen. Die Stirnfläche 24 des Pumpkolbens 22 und die ihr zugewandte Stirnfläche 26 des Verschlusses 25 schließen Luft in einem Pumpvolumen 27 ein.The pumping device 5 ( Fig. 2 ) fills the pressure chamber 4 with air until the time required for the setting process air quantity and / or the pressure necessary for the setting process is reached. The pump device 5 has a linearly moving pump piston 22. In the illustrated embodiment, the pump piston 22 is guided along the working axis 11, but the pump piston 22 can also be guided along another axis. 11 The pumping piston 22 runs within a hollow pumping cylinder 23. The cross section of the pumping piston 22 and the internal cross section of the pumping cylinder 23 are precisely fitting to ensure a pressure-tight closure. Sealing rings on the pump piston 22 can compensate for manufacturing tolerances. An end face 24 of the pump piston 22 opposite the pump cylinder 23 is closed by a stationary closure 25 . The end face 24 of the pumping piston 22 and the end face 26 of the closure 25 facing it include air in a pumping volume 27 .

Der Pumpkolben 22 wird durch eine Magnetspule 28 längs der Achse 11 bewegt. Die Magnetspule 28 ist um den Pumpzylinder 23 angeordnet, vorzugsweise ist die Magnetspule 28 koaxial zu der Achse 11 des Pumpzylinders 23. Der Antrieb basiert auf Reluktanzkräften, welche auf den Pumpkolben 22 wirken. Der Pumpkolben 22 ist aus einem magnetischen, vorzugsweise ferromagnetischen Material. Das von der Magnetspule 28 in dem Pumpzylinder 23 erzeugte Magnetfeld zieht den Pumpkolben 22 in den Pumpzylinder 23 hinein.The pumping piston 22 is moved by a magnetic coil 28 along the axis 11. The magnet coil 28 is arranged around the pump cylinder 23 , preferably the magnet coil 28 is coaxial with the axis 11 of the pump cylinder 23. The drive is based on reluctance forces, which act on the pump piston 22 . The pumping piston 22 is made of a magnetic, preferably ferromagnetic material. The magnetic field generated by the magnet coil 28 in the pump cylinder 23 draws the pump piston 22 into the pump cylinder 23 .

Der Pumpkolben 22 ist aus einem weichmagnetischen Material, dessen Koerzitivfeldstärke geringer als 1000 A/m ist. Ein schwaches externes Magnetfeld kann eine bestehende Polarisation in dem Pumpkolben 22 bereits ändern oder auflösen. Die von der Magnetspule 28 eingeprägte magnetische Polarisation bleibt daher im wesentlichen in dem Pumpkolben 22 nur für die Dauer des von der Magnetspule 28 angelegten Feldes erhalten. Der Pumpkolben 22 ist beispielsweise aus ferromagnetischem Stahl, vorzugsweise aus einem weichgeglühten Stahl.The pumping piston 22 is made of a soft magnetic material whose coercive force is less than 1000 A / m. A weak external magnetic field may already change or resolve an existing polarization in the pumping piston 22 . The from the magnetic coil 28 impressed magnetic polarization therefore remains essentially in the pumping piston 22 only for the duration of the magnetic coil 28 applied field. The pumping piston 22 is for example made of ferromagnetic steel, preferably of a soft-annealed steel.

Der Verschluss 25 ist aus einem weichmagnetischen Material, beispielsweise dem gleichen Material wie der Pumpkolben 22. Das von der Magnetspule 28 erzeugte Magnetfeld wird von dem Verschluss 25 in den Pumpzylinder 23 eingeleitet. Das Magnetfeld verläuft zwischen der Stirnfläche 24 des Pumpkolbens 22 und der Stirnfläche 26 des Verschlusses 25 parallel zu der Achse 11. Der Verschluss 25 ragt längs der Achse 11 in die Magnetspule 28 hinein. Ein vorderer Endabschnitt 29 der Magnetspule 28 überlappt somit mit dem Verschluss 25. Der vordere Endabschnitt 29 nimmt wenigstens 10 % der Magnetspule 28 ein. Eine Länge 30 des vorderen Endabschnitts 29 liegt vorzugsweise zwischen 10 % und 30 % der Länge 31 des Magnetspule 28. Der Pumpkolben 22 tritt nie vollständig aus der Magnetspule 28 heraus. Bei der Grundstellung des Pumpkolbens 22, d.h. in seiner aus dem Pumpzylinder 23 am weitesten ausgerückten Stellung, überlappt der Pumpkolben 22 mit einem hinteren Endabschnitt 32 der Magnetspule 28. Der hintere Endabschnitt 32 hat eine Länge 33 von wenigstens 10 % der Länge 31 der Magnetspule 28, vorzugsweise bis zu 20 % der Länge 31 der Magnetspule 28. Das Pumpvolumen 27 liegt vollständig innerhalb der Magnetspule 28 mit einer Länge 34 von höchstens 80 % der Magnetspule 28. The shutter 25 is made of a soft magnetic material, for example, the same material as the pump piston 22. The magnetic field generated by the magnetic coil 28 is introduced from the shutter 25 into the pump cylinder 23 . The magnetic field extends between the end face 24 of the pump piston 22 and the end face 26 of the shutter 25 parallel to the axis 11. The shutter 25 protrudes into the magnet coil 28 along the axis 11 . A front end portion 29 of the solenoid 28 thus overlaps with the shutter 25. The front end portion 29 occupies at least 10% of the solenoid coil 28 . A length 30 of the front end portion 29 is preferably between 10% and 30% of the length 31 of the solenoid coil 28. The pump piston 22 never fully exits the solenoid coil 28 . In the basic position of the pumping piston 22, ie in its position which is the furthest out of the pumping cylinder 23 , the pump piston 22 overlaps a rear end portion 32 of the magnet coil 28. The rear end portion 32 has a length 33 of at least 10% of the length 31 of the magnet coil 28 , Preferably up to 20% of the length 31 of the solenoid coil 28. The pumping volume 27 is completely within the magnetic coil 28 having a length 34 of at most 80% of the magnetic coil 28th

Das Pumpvolumen 27 ist deutlich geringer als das Volumen der Druckkammer 4. Beispielsweise beinhaltet das Pumpvolumen 27 weniger als 20 %, vorzugsweise zwischen 5 % und 10 %. der notwendigen Luftmenge für einen Setzvorgang. Die Effizienz der Pumpeinrichtung 5 steigt stark nicht-linear mit zunehmender Annäherung des Pumpkolbens 22 an den Verschluss 25. Die Effizienz des Gesamtsystems des Setzgeräts 1 wird durch das kleine Pumpvolumen 27 anstelle eines Pumpvolumens in der Größenordnung der Druckkammer 4 gesteigert, trotz des zusätzlichen Aufwands die Druckkammer 4 bereitzustellen und die durch die Druckkammer 4 einhergehenden Verluste.The pumping volume 27 is significantly less than the volume of the pressure chamber 4. For example, the pumping volume 27 contains less than 20%, preferably between 5% and 10%. the necessary amount of air for a setting process. The efficiency of the pumping device 5 increases strongly non-linearly as the pumping piston 22 approaches the closure 25. The efficiency of the overall system of the setting device 1 is increased by the small pumping volume 27 instead of a pumping volume on the order of the pressure chamber 4 , despite the additional expense Provide pressure chamber 4 and the accompanying pressure chamber 4 losses.

Die Pumpeinrichtung 5 wird von einer Steuerungseinrichtung 35 angesteuert. Die Steuerungseinrichtung 35 lädt bei Betriebsstart oder nach einem Setzvorgang die Druckkammer 4. Das Laden erfolgt durch eine Sequenz 36 von Strompulsen 37, welche in die Magnetspule 28 eingespeist werden (Fig. 3). Mit jedem der Strompulse 37 wird der Pumpkolben 22 aus seiner Grundstellung in die Magnetspule 28 gezogen und komprimiert die Luft in dem Pumpvolumen 27. Ein Großteil der komprimierten Luft fließt in die Druckkammer 4 ab. Eine Feder 39 und/oder eine zusätzliche Magnetspule 40 können den Pumpkolben 22 aus dem Pumpzylinder 23 bis in die Grundstellung herausziehen. Das Pumpvolumen 27 wird vor dem nächsten Strompuls 37 belüftet. Beispielsweise gibt der Pumpkolben 22 einen Belüftungskanal 41 frei, sobald der Pumpkolben 22 sich in die Grundstellung zurückbewegt. Vorzugsweise wird der Belüftungskanal 41 geöffnet, sobald der Pumpkolben 22 seine Rückwärtsbewegung beginnt. Ein Positionssensor kann ermitteln, ob der Pumpkolben 22 die Grundstellung erreicht hat.The pumping device 5 is controlled by a control device 35 . The control device 35 loads the pressure chamber 4 at the start of operation or after a setting process . The charging takes place through a sequence 36 of current pulses 37 which are fed into the magnet coil 28 ( Fig. 3 ). With each of the current pulses 37 , the pump piston 22 is pulled from its normal position into the magnet coil 28 and compresses the air in the pumping volume 27. A large part of the compressed air flows into the pressure chamber 4 . A spring 39 and / or an additional solenoid 40 , the Pull pump piston 22 out of the pump cylinder 23 to the basic position. The pumping volume 27 is vented before the next current pulse 37 . For example, the pump piston 22 releases a ventilation channel 41 as soon as the pump piston 22 moves back into the basic position. Preferably, the vent passage 41 is opened as soon as the pump piston 22 begins its reverse movement. A position sensor can determine whether the pump piston 22 has reached the home position.

Die Sequenz 36 beinhaltet vorzugsweise wenigstens 5 Strompulse 37, vorzugsweise höchstens 30 Strompulse 37. Die Druckkammer 4 wird von der Pumpeinrichtung 5 entsprechend mit 5 bis 30 Hüben vollgepumpt. Der Energieeintrag der Strompulse 37 nimmt während der Sequenz 36 zu; vorzugsweise wird die Dauer 42 der Strompulse 37 erhöht alternativ oder zusätzlich kann die Amplitude 43 der Strompulse 37 erhöht werden. Die Dauer 42 und die Stromstärke/Amplitude 43 können fest vorgegeben sein. Die Strompulse 37 sind derart abgestimmt, dass der Pumpkolben 22 aus seiner Grundstellung bis zu dem Verschluss 25 gezogen wird, vorzugsweise ohne den Verschluss 25 am Ende zu berühren. Die von der Magnetspule 40 auf den Pumpkolben 22 ausgeübte Kraft steigt bei dem gewählten Aufbau während seiner Bewegung zu dem Verschluss 25 permanent an. Die Charakteristik dieses Anstiegs ist ähnlich zu der Charakteristik des Anstiegs der sich durch die komprimierte Luft aufbauenden Gegenkraft. Die Stromstärke 43 kann während eines Strompulses 37 konstant gehalten sein.The sequence 36 preferably includes at least 5 current pulses 37, preferably at most 30 current pulses 37. The pressure chamber 4 is fully pumped by the pumping device 5 with 5 to 30 strokes. The energy input of the current pulses 37 increases during the sequence 36 ; Preferably, the duration 42 of the current pulses 37 is increased alternatively or additionally, the amplitude 43 of the current pulses 37 can be increased. The duration 42 and the current / amplitude 43 can be fixed. The current pulses 37 are adjusted so that the pumping piston 22 is pulled from its normal position to the closure 25 , preferably without touching the closure 25 at the end. The force exerted by the solenoid 40 on the pumping piston 22 increases permanently in the selected structure during its movement to the shutter 25 . The characteristic of this increase is similar to the characteristic of the increase in the counterforce built up by the compressed air. The current 43 may be kept constant during a current pulse 37 .

Der Verschluss 25 ist mit einem Auslassventil 44, z.B. einem Rückschlagventil, versehen. Das Auslassventil 44 öffnet vorzugsweise sobald der Druck in dem Pumpvolumen 27 den Druck in der Druckkammer 4 übersteigt. Die Pumpeinrichtung 5 erhöht den Druck innerhalb des Pumpvolumens nur geringfügig über den Druck in der Druckkammer 4, um die Luftmenge aus des Pumpvolumen 27 in die Druckkammer 4 zu schieben. Die bei der Kompression auftretenden thermischen Verluste können hierdurch gering gehalten werden. Das Auslassventil 44 schließt sobald sich der Pumpkolben 22 in die Grundstellung zurückbewegt.The closure 25 is provided with an outlet valve 44, eg a check valve. The outlet valve 44 preferably opens as soon as the pressure in the pumping volume 27 exceeds the pressure in the pressure chamber 4 . The pumping device 5 increases the pressure within the pumping volume only slightly above the pressure in the pressure chamber 4 in order to push the amount of air from the pumping volume 27 into the pressure chamber 4 . The thermal losses occurring during compression can thereby be kept low. The exhaust valve 44 closes as soon as the pump piston 22 moves back to the normal position.

Der Anwender kann den Triggerschalter 9 betätigen, um einen Setzvorgang auszulösen. Die Steuerungseinrichtung 35 prüft vorzugsweise zuerst, ob die Druckkammer 4 geladen ist. Falls die Druckkammer 4 ungeladen ist, z.B. nach einer längeren Inaktivität des Setzgeräts 1, lädt die Steuerungseinrichtung 35 die Druckkammer 4. Die Druckkammer 4 wird mit der vollständigen Sequenz 36 der Strompulse 37 geladen. Die Steuerungseinrichtung 35 kürzt die Sequenz 36, falls die Druckkammer 4 teilweise geladen ist. Beispielsweise bestimmt die Steuerungseinrichtung 35 mittels eines Drucksensors den Druck in der Druckkammer 4. In einer Steuertabelle ist zu jedem Druck hinterlegt, wieviele der ersten Strompulse 37 der Sequenz 36 zu überspringen sind, d.h. mit welchem der Strompulse 37 der Sequenz 36 zu beginnen ist. Wenn die Druckkammer 4 geladen ist, öffnet die Steuerungseinrichtung 35 das steuerbare Ventil 20. Die unter Druck in der Druckkammer 4 stehende Luftmenge beschleunigt mittels des Treibkolbens 14 den Stößel 3. Nach dem Setzvorgang wird der Treibkolben 14 zurückgeholt, z.B. mittels einer Pumpe, einer Feder, einem Motor, dem Anwender, und das schaltbare Ventil 20 geschlossen. Das Arbeitsvolumen 18 wird für das Rückholen des Treibkolben 14 vorzugsweise belüftet. Die Steuerungseinrichtung 35 lädt die Druckkammer 4 mittels der Sequenz 36 von Strompulsen 37. The user can operate the trigger switch 9 to initiate a setting process. The controller 35 preferably first checks if the pressure chamber 4 is charged. If the pressure chamber 4 is uncharged, for example after a prolonged inactivity of the setting device 1, the control device 35 loads the pressure chamber 4. The pressure chamber 4 is loaded with the complete sequence 36 of the current pulses 37 . The controller 35 truncates the sequence 36 if the pressure chamber 4 is partially charged. For example, the control device 35 determines the pressure in the pressure chamber 4 by means of a pressure sensor a control table is stored for each print, how many of the first current pulses 37 of the sequence 36 to skip, ie which of the current pulses 37 of the sequence 36 is to begin. When the pressure chamber 4 is loaded, the control device 35 opens the controllable valve 20. The amount of air under pressure in the pressure chamber 4 accelerates the plunger 3 by means of the drive piston 14. After the setting process, the drive piston 14 is retrieved, for example by means of a pump, a spring , a motor, the user, and the switchable valve 20 are closed. The working volume 18 is preferably ventilated for the retrieval of the driving piston 14 . The control device 35 loads the pressure chamber 4 by means of the sequence 36 of current pulses 37.

Die Magnetspule 28 ist vorzugsweise von einem Magnetjoch 46 umgeben. Das Magnetjoch 46 deckt mit jeweils einem Ring 47 die beiden Stirnseiten 48 der Magnetspule 28 ab. Das Magnetjoch 46 reicht in radialer Richtung bis an den Pumpkolben 22 bzw. den Verschluss 25 heran. Parallel zu der Achse 11 verlaufende Rippen 49 des Magnetjochs 46 verbinden die beiden Ringe 47. Das Magnetjoch 46 ist beispielsweise aus einzelnen Blechen eines ferromagnetischen Stahls gebildet.The magnet coil 28 is preferably surrounded by a magnetic yoke 46 . The yoke 46 covers each of a ring 47, the two end faces 48 of the solenoid coil 28 from. The magnet yoke 46 extends in the radial direction as far as the pump piston 22 or the closure 25 . Ribs 49 of the magnetic yoke 46 , which extend parallel to the axis 11 , connect the two rings 47. The magnetic yoke 46 is formed, for example, from individual sheets of a ferromagnetic steel.

Der Pumpkolben 22 hat einen schalenfömigen Aufbau aus einer äußeren Schale 50 und einem Kern 51. Die radial äußerste Schale 50 ist aus einem ferromagnetischen Material. Das Magnetfeld wird innerhalb der äußeren Schale 50 geleitet. Eine Wandstärke der äußeren Schale 50 liegt im Bereich zwischen 5 % und 25 % des Durchmessers des Pumpkolbens 22. Ein Kern 51 des Pumpkolben 22 kann hohl sein oder mit einem nicht-metallischen Material, z.B. Kunststoff gefüllt sein. Die Stirnfläche 26 ist vorzugsweise eine Platte aus Stahl, um sich während der Kompression nicht zu verformen. Alternativ kann der Pumpkolben 22 ein massiver Zylinder aus einem ferromagnetischen Material, z.B. Stahl sein.The pumping piston 22 has a shell-like construction of an outer shell 50 and a core 51. The radially outermost shell 50 is made of a ferromagnetic material. The magnetic field is conducted inside the outer shell 50 . A wall thickness of the outer shell 50 is in the range between 5% and 25% of the diameter of the pump piston 22. A core 51 of the pump piston 22 may be hollow or be filled with a non-metallic material, eg plastic. The end face 26 is preferably a steel plate so as not to deform during compression. Alternatively, the pump piston 22 may be a solid cylinder of a ferromagnetic material, eg steel.

Fig. 4 zeigt eine Ausgestaltung des Führungszylinders 15 für den Treibkolben 14 und der Druckkammer 4. Die Druckkammer 4 ist permanent zu dem Arbeitsvolumen 18 in dem Führungszylinders 15 offen. Der Treibkolben 14 bildet das schaltbare Ventil 20 und hindert die Luft in der Druckkammer 4 am Ausströmen, bis ein Setzvorgang ausgelöst wird. Ein Sperrmechanismus 52, z.B. eine Klinke, hält den Treibkolben 14 in seiner Grundstellung. Der Sperrmechanismus 52 kann durch die Steuerungseinrichtung 35 gelöst werden, worauf der Treibkolben 14 druckbeaufschlagt in Setzrichtung 13 beschleunigt wird. Fig. 4 shows an embodiment of the guide cylinder 15 for the driving piston 14 and the pressure chamber 4. The pressure chamber 4 is permanently open to the working volume 18 in the guide cylinder 15 . The driving piston 14 forms the switchable valve 20 and prevents the air in the pressure chamber 4 from flowing out until a setting process is triggered. A locking mechanism 52, such as a pawl, holds the driving piston 14 in its normal position. The locking mechanism 52 can be released by the control device 35 , whereupon the driving piston 14 is pressurized in the setting direction 13 is accelerated.
