- the transport process is effected by a conveyor pawl attached to a conveyor cylinder, which engages between the individual nails of a nail strip and conveys the row of nails in the direction of the expulsion channel.
- a disadvantage of this embodiment is that only nail strips can be processed whose nails are at a certain distance from one another within the nail strip, so that the feed pawl can engage in the respective intermediate space. It is therefore not possible with this device to process nails that are stored in a space-saving manner on the shaft within the nail strip.
- the object of the present invention is to provide a nail driving device of the type mentioned at the outset, with which nail strips can also be reliably processed, in which the nails lie not on a gap, but rather on shaft after shaft. As a result, the loading capacity of the magazine can be increased considerably with the same external dimensions.
- the nail transport device has a transport boat which is guided in the longitudinal direction of the magazine by means of the piston rod of the feed cylinder and which has a preferably wedge-shaped nail strip separator element that becomes effective during the backward movement, that the nail strip separator element of the transport boat is designed in this way is that when it moves backwards with lateral displacement of any remaining nail strips in the magazine between the nail strips pressed against the contact surface and any remaining nail strips in the magazine, the transport element moves in as one on the side when the transport boat moves forward separated nail strips attacking feed clamp is designed so that each nail strips lying against the stop surface can be clamped in a force-locking manner between the transport boat and the feed clamp and can thus be moved forward with the transport boat.
- a further development of the invention provides a retaining device for the separated nail strip that becomes effective when the transport boat moves backward.
- the nail strip is raised by the nail strip separator organ when the transport boat moves backwards relative to the remaining nail strips, as a result of which the nail heads of the separated nail strip and the nail heads of the adjacent nail strip are reliably prevented from getting caught.
- a further development of the invention further provides that the feed clamp is attached to the transport boat in such a way that the clamping of the nail strip between the transport ship and the feed clamp becomes firmer when it moves forward, but is released when it moves backwards .
- a quick and reliable clamping of the nail strip between the feed clamp and the transport boat can be ensured in that the feed clamp is always pressed resiliently against the contact surface of the nail strip.
- the retaining device has a retaining claw that is designed to be resiliently foldable when the nail strip is advanced.
- the axis of rotation of the retaining device is also located behind the clamping point of the retaining claw with the nail strip, which guarantees a reliable clamping effect when the transport boat moves backwards with the feed clamp.
- an advantageous embodiment of the invention provides that the retaining device is attached to a resilient tab.
- a further embodiment of the invention provides that the possible movement path of the transport boat is a multiple of the nail diameter.
- the magazine can be filled up particularly easily if the nails are guided with their tips pointing downwards against a height-adjustable bottom of the magazine. As a result, nails of different lengths can also be processed.
- the guide bar of the movable transport boat also serves as the stop surface and rear wall of the magazine.
- a still further embodiment of the invention provides grips on the transport element and on the retaining device, with which jams of the separated nail strips can be easily released in the event of malfunctions.
- the feed cylinder can be designed both as a double-acting cylinder and as a single-acting cylinder with spring return and can thus be adapted to different design requirements.

- the separated nail strip can be under the pressure of the feed cylinder or the return spring during the nail driving process.
- the magazine can be filled particularly easily and ensure an effective pushing of the nail strips against the contact surface if the spring element is designed as a spring-preloaded bracket which can extend over the entire length of the magazine.
- the spring element is attached so that it can be relaxed and opened, which enables the magazine to be loaded with one hand.
- the spring element can be arranged to be folded away together with the upper cover of the magazine.
- the bottom of the magazine is attached in a height-adjustable manner in a further development of the invention.
- a run-up curve is provided for lifting the separated nail strips on the guide bar, as a result of which the nail heads get caught or tilted even more reliably.
- the nails are held in the inlet slot by a pressure spring so that they cannot get into the expulsion channel unintentionally.
- the nail transport device has a transport boat 1, which is guided on a guide bar 16 along a magazine 11 for nail strips 5 with a shaft 10 on nails and cooperates with a transport element 3 designed as a feed clamp, as shown in FIG. 1a.
- a nail strip is to be used with the nail transport device 5 in the direction of an inlet slot of an expulsion channel in the device mouthpiece in FIG. 1a are thus transported upward, so that the foremost nail 10 in the expulsion channel is available for expulsion.
- the transport boat 1 is fixed for this purpose on a piston rod 7 extending in the magazine longitudinal direction of a delivery cylinder 6, not shown, and formed at its rear end as a wedge-shaped nail strip separator organ 12, in such a way that when moving backwards (downward in Fig.
- Transport boat 1 due to its asymmetrical wedge shape of the nail strips 5 pressed against a nail bar 5 formed by a spring element 8 with the other nail strips 5 in the magazine 11 against a guide bar 16 provided with a guide edge 16 for the nail heads or its continuation remaining nail strips 5 in the magazine 11 is separated and raised.
- the transport boat 1 travels between the last two nail strips 5, as can be seen in FIG. 1a.
- the feed clamp 3 is articulated via an axis of rotation 13 on the connecting web of the transport boat 1 with the piston rod 7 and consists of a locking claw 14 and a handle 17.
- the axis of rotation 13 lies behind the clamping point 20 of the locking claw 14, which against the side of the separated and nail strip to be transported 5 is pressed spring-biased. In this way, the clamping force between the transport boat 1 and the locking claw 14 increases when these two elements move in the conveying direction in FIG. 1 a upward of the nail strip 5.
- a retaining device 4 which is attached to a tab 29 via an axis of rotation 19, which in turn is articulated via an axis of rotation 30 and a spring 31 to the guide bar 16, such as 1b, the retaining device 4 having a retaining claw 15 and a handle 18.
- the retaining claw 15 has a clamping point 21, which lies in the conveying direction in front of the axis of rotation 19, so that the spring-loaded retaining claw 15 releases the nail strip 5 when it moves forward, but locks it when trying to push the nail strip 5 back and only together with it resiliently arranged tab 29 withdraws a short distance during the driving-in process when the head of the foremost nail 10 passes the shaft end of the next nail and in doing so pushes back a little.
- the piston rod 7 of the single-acting delivery cylinder 6 is pressed back into the delivery cylinder 6 by a return spring 22, which is supported on one side against the transport boat 1 and on the other side against a guide sleeve 25 held on the bar 16.
- a buffer element 24 is arranged in front of the stop surface of the guide sleeve 25 for shock absorption.
- FIG. 2 also shows the housing of the magazine 11, which is open on one side. It consists of a height-adjustable base 9 which serves to guide the nail strips 5, a spring element 8, a cover 23 which can be pivoted away, and the guide bar 16 with a stop surface 2.
- a plurality of nail strips 5, as can be seen from FIG. 1, are pressed together by the spring element 8 in the direction of the stop surface 2 of the nail transport device, so that when a first nail strip 5 is used, the next one moves to the stop surface 2.
- the transport boat 1 travels along the guide bar 16 due to the movement of the feed cylinder 6 or the return spring 22. If the feed cylinder 6 is pressurized by the pneumatic nail driving device, the transport boat 1 initially moves back, its nail stripe separator organ 12 resting against the stop surface 2 Nail strips 5 from the remaining nail strips 5 of the magazine 11, as mentioned, separated and slightly raised.
- the locking claw 14 of the feed clamp 3 is rotated back about its axis of rotation 13 by resilient contact with the first nail strip 5.
- the delivery cylinder 6 is vented.
- the return spring 22 now presses the transport boat 1 in the conveying direction.
- the separated nail strip 5 is clamped between the nail strip separator organ 12 and the locking claw 14 and moved by the transport boat 1 in the conveying direction until the foremost nail 10 of the transported nail strip 5 passes through the inlet slot into the drive-out channel of the nail driving device.
- the stationary retention device 4 with retention claw 15, which works on the same principle as the feed clamp 3, ensures that the nail strip 5 remains in the advanced position when the transport boat 1 returns.
- the clamping of the nail strip 5 between the nail strip separating member 12 and the locking claw 14 of the transport boat 1 is automatically released when the transport boat 1 returns, since the clamping point 20 in the conveying direction in front of the axis of rotation 13 of the locking claw 14 is arranged.
- a pressure spring 28 ensures that the nails 10 at the end of the nail strip 5 cannot get into the expulsion channel in an uncontrolled manner, but rather are held in their position in the inlet slot until they are further conveyed in the direction of the expulsion channel by the next nail strip 5.
- a second nail strip 5 is pressed by the spring element 8 against the stop surface 2 of the nail transport device, separated from the remaining nail strips 5 by the nail strip separating member 12 and raised and advanced in the conveying direction analogously to the first nail strip 5.
- the operation of the magazine 11 can best be seen in FIG. 4.
- the handle 32 is first unlatched, as a result of which the spring element 8 can be folded back. Then any number of nail strips 5 can be reloaded up to the maximum capacity. Then the handle 32 is snapped back in, whereby the spring element 8 acts on the nail strips under spring force.
- the bottom 9 of the magazine 11 is height-adjustable and can thus be adjusted to different lengths of the nails 10.
- both on the feed clamp 3 and on the retaining device 4 handle pieces 17 and 18 are attached, with which the clamping of the separated nail strip 5 can be released manually if necessary.
- the nail strip separator organ 12 can be folded back with the aid of a fast interference suppression 33 in order to be able to remove any jammed nails 10 or nail strips 5 from the inlet slot of the nail transport device.

Eine solche Vorrichtung ist aus der EP-A-0 119 542 bekannt. Das dort beschriebene Nageleintreibgerät weist ein zur Aufnahme von mehreren Nagelstreifen vorgesehenes Magazin auf, welches mit einer Nageltransporteinrichtung versehen ist. Der Transportvorgang wird durch eine an einem Förderzylinder angebrachte Förderklinke bewirkt, die zwischen die einzelnen Nägel eines Nagelstreifens eingreift und die Nagelreihe in Richtung des Austreibkanals fördert. Als nachteilig erweist sich bei dieser Ausführungsform, daß nur Nagelstreifen verarbeitet werden können, deren Nägel innerhalb des Nagelstreifens einen gewissen Abstand voneinander aufweisen, so daß die Förderklinke in den jeweiligen Zwischenraum eingreifen kann. Es ist daher mit dieser Vorrichtung nicht möglich, Nägel zu verarbeiten, die innerhalb des Nagelstreifens platzsparend Schaft an Schaft magaziniert sind.Such a device is known from EP-A-0 119 542. The nail driving device described there has a magazine which is provided for receiving a plurality of nail strips and which is provided with a nail transport device. The transport process is effected by a conveyor pawl attached to a conveyor cylinder, which engages between the individual nails of a nail strip and conveys the row of nails in the direction of the expulsion channel. A disadvantage of this embodiment is that only nail strips can be processed whose nails are at a certain distance from one another within the nail strip, so that the feed pawl can engage in the respective intermediate space. It is therefore not possible with this device to process nails that are stored in a space-saving manner on the shaft within the nail strip.
Aufgabe der vorliegenden Erfindung ist die Schaffung eines Nageleintreibgeräts der eingangs genannten Art, mit welchem auch Nagelstreifen zuverlässig verarbeitet werden können, in welchen die Nägel nicht auf Lücke, sondern Schaft an Schaft liegen. Dadurch läßt sich die Ladekapazität des Magazins bei gleichen Außenabmessungen erheblich steigern.The object of the present invention is to provide a nail driving device of the type mentioned at the outset, with which nail strips can also be reliably processed, in which the nails lie not on a gap, but rather on shaft after shaft. As a result, the loading capacity of the magazine can be increased considerably with the same external dimensions.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Nageltransporteinrichtung ein Transportschiffchen aufweist, welches mit Hilfe der Kolbenstange des Förderzylinders in Längsrichtung des Magazins verfahrbar geführt ist und welches ein bei der Rückwärtsbewegung wirksam werdendes, vorzugsweise keilförmig ausgebildetes Nagelstreifenseparierorgan aufweist, daß das Nagelstreifenseparierorgan des Transportschiffchens derart ausgebildet ist, daß es bei dessen Rückwärtsbewegung unter seitlichem Verschieben der ggf. restlichen in dem Magazin befindlichen Nagelstreifen zwischen den an die Anlagefläche angedrückten Nagelstreifen und die ggf. restlichen in dem Magazin befindlichen Nagelstreifen einfährt, daß das Transportelement als eine bei Vorwärtsbewegung des Transportschiffchens seitlich an dem separierten Nagelstreifen angreifende Vorschubklemme so ausgebildet ist, daß der jeweils an der Anschlagfläche anliegende Nagelstreifen zwischen dem Transportschiffchen und der Vorschubklemme kraftschlüssig einklemmbar und dadurch mit dem Transportschiffchen vorwärtsbewegbar ist.This object is achieved according to the invention in that the nail transport device has a transport boat which is guided in the longitudinal direction of the magazine by means of the piston rod of the feed cylinder and which has a preferably wedge-shaped nail strip separator element that becomes effective during the backward movement, that the nail strip separator element of the transport boat is designed in this way is that when it moves backwards with lateral displacement of any remaining nail strips in the magazine between the nail strips pressed against the contact surface and any remaining nail strips in the magazine, the transport element moves in as one on the side when the transport boat moves forward separated nail strips attacking feed clamp is designed so that each nail strips lying against the stop surface can be clamped in a force-locking manner between the transport boat and the feed clamp and can thus be moved forward with the transport boat.
Um eine zuverlässige Funktion der Nageltransporteinrichtung zu gewährleisten, sieht eine Weiterbildung der Erfindung eine bei der Rückwärtsbewegung des Transportschiffchens wirksam werdende Rückhaltevorrichtung für den separierten Nagelstreifen vor.
Bei einer weiteren Ausgestaltung der Erfindung wird der Nagelstreifen durch das Nagelstreifenseparierorgan bei Rückwartsbewegung des Transportschiffchens gegenüber den restlichen Nagelstreifen angehoben, wodurch ein Verhaken der Nagelköpfe des separierten Nagelstreifens mit den Nagelköpfen des benachbarten Nagelstreifens zuverlässig vermieden wird.In order to ensure reliable functioning of the nail transport device, a further development of the invention provides a retaining device for the separated nail strip that becomes effective when the transport boat moves backward.
In a further embodiment of the invention, the nail strip is raised by the nail strip separator organ when the transport boat moves backwards relative to the remaining nail strips, as a result of which the nail heads of the separated nail strip and the nail heads of the adjacent nail strip are reliably prevented from getting caught.
Um eine besonders zuverlässige Funktionsweise der Nageltransporteinrichtung sicherzustellen, sieht eine Weiterbildung der Erfindung ferner vor, daß die Vorschubklemme so an dem Transportschiffchen angebracht ist, daß die Klemmung des Nagelstreifens zwischen dem Transportschiffchen und der Vorschubklemme bei dessen Vorwärtsbewegung fester wird, sich bei dessen Rückwärtsbewegung dagegen löst.In order to ensure a particularly reliable functioning of the nail transport device, a further development of the invention further provides that the feed clamp is attached to the transport boat in such a way that the clamping of the nail strip between the transport ship and the feed clamp becomes firmer when it moves forward, but is released when it moves backwards .
Dies läßt sich konstruktiv besonders einfach dadurch erzielen, daß die Drehachse der Vorschubklemme hinter dem Klemmpunkt der Vorschubklemme mit der Nagelreihe liegt.This can be achieved in a structurally particularly simple manner in that the axis of rotation of the feed clamp lies behind the clamping point of the feed clamp with the row of nails.
Eine schnelle und zuverlässige Klemmung des Nagelstreifens zwischen Vorschubklemme und Transportschiffchen läßt sich dadurch gewährleisten, daß die Vorschubklemme stets federnd gegen die Anlagefläche des Nagelstreifens gedrückt wird.A quick and reliable clamping of the nail strip between the feed clamp and the transport boat can be ensured in that the feed clamp is always pressed resiliently against the contact surface of the nail strip.
Eine Weiterbildung der Erfindung sieht vor, daß die Rückhaltevorrichtung eine beim Vorschub des Nagelstreifens federnd zurückklappbar ausgebildete Rückhalteklaue aufweist.A further development of the invention provides that the retaining device has a retaining claw that is designed to be resiliently foldable when the nail strip is advanced.
Bei einer anderen Ausgestaltung der Erfindung liegt auch die Drehachse der Rückhaltevorrichtung hinter dem Klemmpunkt der Rückhalteklaue mit dem Nagelstreifen, wodurch eine zuverlässige Klemmwirkung bei Rückwärtsbewegung des Transportschiffchens mit der Vorschubklemme garantiert wird.In another embodiment of the invention, the axis of rotation of the retaining device is also located behind the clamping point of the retaining claw with the nail strip, which guarantees a reliable clamping effect when the transport boat moves backwards with the feed clamp.
Um den beim Eintreibvorgang eines D-Kopf-Nagels zurückweichenden Nagelstreifen, der durch die Rückhaltevorrichtung geklemmt ist, das kurze Zurückweichen zu ermöglichen, sieht eine vorteilhafte Ausgestaltung der Erfindung vor, daß die Rückhaltevorrichtung an einer federnden Lasche angebracht ist.In order to allow the short retraction during the driving-in process of a D-head nail, which is clamped by the retaining device, an advantageous embodiment of the invention provides that the retaining device is attached to a resilient tab.
Um einen unter allen Arbeitsbedingungen ausreichenden Nagelvorschub sicherzustellen, sieht eine weitere Ausgestaltung der Erfindung vor, daß der mögliche Bewegungsweg des Transportschiffchens ein Vielfaches des Nageldurchmessers beträgt.In order to ensure a sufficient nail advance under all working conditions, a further embodiment of the invention provides that the possible movement path of the transport boat is a multiple of the nail diameter.
Das Magazin läßt sich besonders einfach auffüllen, wenn die Nägel mit ihren nach unten gerichteten Spitzen an einem höhenverstellbaren Boden des Magazins anliegend geführt werden. Hierdurch sind auch unterschiedlich lange Nägel verarbeitbar.The magazine can be filled up particularly easily if the nails are guided with their tips pointing downwards against a height-adjustable bottom of the magazine. As a result, nails of different lengths can also be processed.
Bei einer konstruktiv zweckmäßigen Weiterbildung der Erfindung dient die Führungsleiste des bewegbaren Transportschiffchens zugleich als Anschlagfläche und Rückwand des Magazins.In a structurally expedient development of the invention, the guide bar of the movable transport boat also serves as the stop surface and rear wall of the magazine.
Eine noch weitere Ausgestaltung der Erfindung sieht Griffstücke an dem Transportelement und an der Rückhaltevorrichtung vor, mit denen Verklemmungen der separierten Nagelstreifen bei Fehlfunktionen leicht gelöst werden können.A still further embodiment of the invention provides grips on the transport element and on the retaining device, with which jams of the separated nail strips can be easily released in the event of malfunctions.
Der Förderzylinder kann sowohl als doppelt wirkender Zylinder als auch als einfach wirkender Zylinder mit Federrückholung ausgebildet sein und so an unterschiedliche konstruktive Anforderungen angepaßt werden.The feed cylinder can be designed both as a double-acting cylinder and as a single-acting cylinder with spring return and can thus be adapted to different design requirements.
Besonders wirksam und kostensparend ist die Versorgung des Förderzylinders mit Luft aus dem Nageleintreibgerät selbst.The supply of air to the delivery cylinder from the nail driving device itself is particularly effective and cost-saving.
Um Fehlfunktionen beim Austreiben des vordersten Nagels auszuschließen, kann der separierte Nagelstreifen während des Nageleintreibvorgangs unter dem Druck des Förderzylinders bzw. der Rückholfeder stehen.To rule out malfunctions when driving out the foremost nail, the separated nail strip can be under the pressure of the feed cylinder or the return spring during the nail driving process.
Das Magazin läßt sich besonders einfach füllen und ein wirksames Nachschieben der Nagelstreifen gegen die Anlagefläche sicherstellen, wenn das Federelement als ein federvorgespannter Bügel ausgebildet ist, welcher sich über die gesamte Länge des Magazins erstrecken kann.The magazine can be filled particularly easily and ensure an effective pushing of the nail strips against the contact surface if the spring element is designed as a spring-preloaded bracket which can extend over the entire length of the magazine.
Bei einer weiteren vorteilhaften Ausgestaltung der Erfindung ist das Federelement entspannbar und aufklappbar angebracht, wodurch eine bequeme Einhand-Beladung des Magazins ermöglicht wird.In a further advantageous embodiment of the invention, the spring element is attached so that it can be relaxed and opened, which enables the magazine to be loaded with one hand.
Um eine noch bessere Zugänglichkeit und Bedienbarkeit des Magazins zu gewährleisten, kann das Federelement zusammen mit der oberen Abdeckung des Magazins wegklappbar angeordnet sein.In order to ensure even better accessibility and operability of the magazine, the spring element can be arranged to be folded away together with the upper cover of the magazine.
Zur sicheren und störungsfreien Verarbeitung von Nägeln unterschiedlicher Schaftlängen ist bei einer Weiterbildung der Erfindung der Boden des Magazins höhenverstellbar angebracht.For a safe and trouble-free processing of nails of different shaft lengths, the bottom of the magazine is attached in a height-adjustable manner in a further development of the invention.
Eine vorteilhafte Angriffsstelle in der Mitte des Nagelschaftes ergibt sich bei kompakter Bauweise, wenn die Vorschubklemme und/oder die Rückhaltevorrichtung durch einen Längsschlitz in der Führungsleiste hindurchgreifen bzw. hindurchgreift.An advantageous point of attack in the middle of the nail shaft results in a compact design if the feed clamp and / or the retaining device reach through or reach through a longitudinal slot in the guide bar.
In einer weiteren Ausführungsform der Erfindung ist eine Auflaufkurve für das Anheben der separierten Nagelstreifen an der Führungsleiste vorgesehen, wodurch ein Verhaken bzw. Verkanten der Nagelköpfe noch zuverlässiger vermieden wird. Um evtl. verklemmende Nägel einfach und bequem aus dem Einlaßschlitz entnehmen zu können, ist eine vorteilhafte Weiterbildung der Erfindung mit einer Schnellentstörung ausgerüstet.In a further embodiment of the invention, a run-up curve is provided for lifting the separated nail strips on the guide bar, as a result of which the nail heads get caught or tilted even more reliably. In order to be able to remove jammed nails easily and conveniently from the inlet slot, an advantageous further development of the invention is equipped with a quick interference suppression.
Bei einer weiteren vorteilhaften Ausgestaltung der Erfindung werden die Nägel im Einlaßschlitz von einer Anpreßfeder gehalten, damit sie nicht ungewollt in den Austreibkanal gelangen können.In a further advantageous embodiment of the invention, the nails are held in the inlet slot by a pressure spring so that they cannot get into the expulsion channel unintentionally.
Dem sicheren Verschieben der Nägel dient es, wenn die Nägelköpfe auf einer Führungskante der Führungsleiste geführt sind.It is used to safely move the nails if the nail heads are guided on a leading edge of the guide bar.
Nachfolgend wird die Erfindung anhand von Ausführungsbeispielen und der Zeichnung beschrieben.The invention is described below using exemplary embodiments and the drawing.

Die Nageltransporteinrichtung weist ein Transportschiffchen 1 auf, welches auf einer Führungsleiste 16 längs eines Magazins 11 für Nagelstreifen 5 mit Schaft an Schaft liegenden Nägeln 10 geführt ist und mit einem als Vorschubklemme ausgebildeten Transportelement 3 zusammenwirkt, wie in Fig. 1a dargestellt ist. Mit der Nageltransporteinrichtung soll ein Nagelstreifen 5 in Richtung eines Einlaßschlitzes eines Austreibkanals in dem Gerätemundstück in Fig. 1a also nach oben transportiert werden, so daß der jeweils vorderste Nagel 10 in dem Austreibkanal zum Austreiben zur Verfügung steht. Das Transportschiffchen 1 ist zu diesem Zweck fest auf einer in Magazinlängsrichtung verlaufenden Kolbenstange 7 eines nicht dargestellten Förderzylinders 6 festgelegt und an seinem rückwärtigen Ende als keilförmiges Nagelstreifenseparierorgan 12 ausgebildet, und zwar in der Weise, daß bei Rückwärtsbewegung (in Fig. 1a nach unten) des Transportschiffchens 1 aufgrund seiner asymetrischen Keilform der von einem als Bügel ausgebildeten Federelement 8 mit den anderen Nagelstreifen 5 im Magazin 11 an eine von einer mit einer Führungskante für die Nagelköpfe ausgestatteten Führungsleiste 16 bzw. deren Fortsetzung gebildete Anlagefläche 2 des Magazins 11 gedrückte Nagelstreifen 5 gegenüber den restlichen Nagelstreifen 5 in dem Magazin 11 separiert und angehoben wird. Hierbei fährt das Transportschiffchen 1 zwischen die beiden letzten Nagelstreifen 5, wie aus Fig. 1a ersichtlich ist. Die Vorschubklemme 3 ist über eine Drehachse 13 an dem Verbindungssteg des Transportschiffchens 1 mit der Kolbenstange 7 angelenkt und besteht aus einer Sperrklaue 14 und einem Griffstück 17. Die Drehachse 13 liegt dabei hinter dem Klemmpunkt 20 der Sperrklaue 14, welche gegen die Seite des separierten und zu transportierenden Nagelstreifens 5 federvorgespannt gedrückt wird. Auf diese Weise erhöht sich die Klemmkraft zwischen Transportschiffchen 1 und Sperrklaue 14 bei Bewegung dieser beiden Elemente in Förderrichtung in Fig. 1a nach oben des Nagelstreifens 5.The nail transport device has a
Weiter vorne in Förderrichtung befindet sich eine Rückhaltevorrichtung 4, die über eine Drehachse 19 an einer Lasche 29 angebracht ist, welche ihrerseits über eine Drehachse 30 und mit einer Feder 31 ander Führungsleiste 16 angelenkt ist, wie aus Fig. 1b zu erkennen ist, wobei die Rückhaltevorrichtung 4 eine Rückhalteklaue 15 sowie ein Griffstück 18 aufweist. Wie die Sperrklaue 14 weist die Rückhalteklaue 15 einen Klemmpunkt 21 auf, welcher in Förderrichtung vor der Drehachse 19 liegt, so daß die federvorgespannte Rückhalteklaue 15 bei Vorwärtsbewegung des Nagelstreifens 5 diesen freigibt, beim Versuch des Zurückschiebens des Nagelstreifens 5 jedoch sperrt und nur zusammen mit der federnd angeordneten Lasche 29 während des Eintreibvorgangs ein kurzes Stück zurückweicht, wenn der Kopf des vordersten Nagels 10 das Schaftende des nächsten Nagels passiert und dabei etw as zurückdrückt.Further forward in the conveying direction is a retaining device 4, which is attached to a
Die Kolbenstange 7 des einfach wirkenden Förderzylinders 6 wird durch eine Rückholfeder 22, die sich auf der einen Seite gegen das Transportschiffchen 1 und auf der anderen Seite gegen eine an der Leiste 16 gehaltene Führungshülse 25 abstützt, in den Förderzylinder 6 zurückgedrückt. Vor der Anschlagfläche der Führungshülse 25 ist zur Stoßdämpfung ein Pufferelement 24 angeordnet.The piston rod 7 of the single-acting delivery cylinder 6 is pressed back into the delivery cylinder 6 by a
In Fig. 2 ist zusätzlich zu der Nageltransporteinrichtung auch das Gehäuse des einseitig offenen Magazins 11 zu erkennen. Es besteht aus einem der Führung der Nagelstreifen 5 dienenden höhenverstellbaren Boden 9, einem Federelement 8, einer wegschwenkbaren Abdeckung 23 sowie der Führungsleiste 16 mit Anschlagfläche 2.In addition to the nail transport device, FIG. 2 also shows the housing of the
In der Führungsleiste 16 ist ein Längsschlitz 26 für die Sperrklaue 14 der Vorschubklemme 3 und eine Auflaufkurve 27 vorgesehen, auf welche der separierte Nagelstreifen 5 bei seiner Vorwärtsförderung mit seinen Nagelköpfen aufläuft, wie in Fig. 3a-d dargestellt ist.In the
Mehrere Nagelstreifen 5 werden, wie aus Fig. 1 ersichtlich, gemeinsam durch das Federelement 8 in Richtung der Anschlagfläche 2 der Nageltransporteinrichtung gedrückt, so daß bei Verbrauch eines ersten Nagelstreifens 5 der nächste an die Anschlagfläche 2 nachrückt. Das Transportschiffchen 1 fährt bedingt durch die Bewegung des Förderzylinders 6 bzw. die Rückholfeder 22 entlang der Führungsleiste 16. Wird der Förderzylinder 6 mit Druck von dem pneumatischen Nageleintreibgerät beaufschlagt, fährt das Transportschiffchen 1 zunächst zurück, wobei sein Nagelstreifenseparierorgan 12 den an der Anschlagfläche 2 anliegenden Nagelstreifen 5 von den restlichen Nagelstreifen 5 des Magazins 11, wie erwähnt, separiert und etwas anhebt. Die Sperrklaue 14 der Vorschubklemme 3 wird dabei durch federnde Anlage an dem ersten Nagelstreifen 5 um ihre Drehachse 13 zurückgedreht. Sobald das Transportschiffchen 1 ganz zurückgefahren ist, wird der Förderzylinder 6 entlüftet. Die Rückholfeder 22 drückt nun das Transportschiffchen 1 in Förderrichtung. Dabei wird der separierte Nagelstreifen 5 zwischen dem Nagelstreifenseparierorgan 12 und der Sperrklaue 14 eingeklemmt und von dem Transportschiffchen 1 in Förderrichtung soweit bewegt, bis der vorderste Nagel 10 des transportierten Nagelstreifens 5 durch den Einlaßschlitz in den Austreibkanal des Nageleintreibgerätes gelangt.A plurality of nail strips 5, as can be seen from FIG. 1, are pressed together by the
Die stationär angebrachte Rückhaltevorrichtung 4 mit Rückhalteklaue 15, die nach dem gleichen Prinzip wie die Vorschubklemme 3 arbeitet, sorgt dafür, daß beim Rücklauf des Transportschiffchens 1 der Nagelstreifen 5 in der vorgeschobenen Position stehenbleibt. Die Klemmung des Nagelstreifens 5 zwischen dem Nagelstreifenseparierorgan 12 und der Sperrklaue 14 des Transportschiffchens 1 löst sich beim Rücklauf des Transportschiffchens 1 selbttätig, da der Klemmpunkt 20 in Förderrichtung vor der Drehachse 13 der Sperrklaue 14 angeordnet ist. Eine Anpreßfeder 28 sorgt dafür, daß die Nägel 10 am Ende des Nagelstreifens 5 nicht unkontrolliert in den Austreibkanal gelangen können, sondern solange in ihrer Position im Einlaßschlitz gehalten werden, bis sie durch den nächsten Nagelstreifen 5 weiter in Richtung Austreibkanal gefördert werden.The stationary retention device 4 with
Sobald der erste Nagelstreifen 5 verarbeitet worden ist, wird ein zweiter Nagelstreifen 5 durch das Federelement 8 gegen die Anschlagfläche 2 der Nageltransporteinrichtung gedrückt, durch das Nagelstreifenseparierorgan 12 von den restlichen Nagelstreifen 5 separiert und angehoben und analog zum ersten Nagelstreifen 5 in Förderrichtung vorgeschoben.As soon as the
Die Funktionsweise des Magazins 11 ist am besten in Fig. 4 zu sehen. Zum Beladen des Magazins 11 wird zunächst der Handhabungsbügel 32 entrastet, wodurch das Federelement 8 zurückgeklappt werden kann. Dann können bis zur maximalen Kapazität beliebig viele Nagelstreifen 5 nachgeladen werden. Anschließend wird der Handhabungsbügel 32 wieder eingerastet, wodurch das Federelement 8 die Nagelstreifen unter Federkraft beaufschlagt. Der Boden 9 des Magazins 11 ist höhenverstellbar angebracht und kann dadurch auf verschiedene Längen der Nägel 10 eingestellt werden.The operation of the
Sowohl an der Vorschubklemme 3 als auch an der Rückhaltevorrichtung 4 sind Griffstücke 17 bzw. 18 angebracht, mit denen die Klemmung des separierten Nagelstreifens 5 im Bedarfsfall manuell gelöst werden kann. Außerdem kann das Nagelstreifenseparierorgan 12 mit Hilfe einer Schnellentstörung 33 zurückgeklappt werden, um eventuell verklemmte Nägel 10 bzw. Nagelstreifen 5 aus dem Einlaßschlitz der Nageltransporteinrichtung entfernen zu können.Both on the
