Definitions
- the present invention relates to a hand-held tacker of the type mentioned in the preamble of claim 1.
- Such hand-held tackers have a displaceably guided Eintreibstössel about the fasteners are driven into a ground.
- the drive source for the drive ram is a mechanical drive spring, which can be tensioned via a clamping mechanism.
- the advantage here is that the mechanical drive spring is inexpensive, whereby such a tacker is inexpensive to manufacture. Since the tensioning process can take several tens to a few hundred milliseconds, especially with strong drive springs, it is advantageous if the tensioning process has already been completed before an actuation of the triggering or trigger switch of the tacking device. It is then further necessary that the drive spring via a locking device directly or indirectly via another element, such. As the drive ram is fixed in its cocked position until the tacker is triggered.
- a generic tacker in which a driving ram is tensioned by a motor-driven clamping mechanism against a drive spring element.
- the driving ram and the spring element can be locked in a cocked position via a locking device.
- the locking device has for this purpose a blocking means which engages lockingly effective on a blocking surface of the drive-in ram.
- the locking device can be unlocked so that it is lifted via a motor-operated mechanism from its locked position and can be converted into a release position.
- the driving ram is moved in this release position of the locking device under the force of the drive spring element in the setting direction to drive a fastener into a workpiece.
- a disadvantage of the known tacker is that the sliding friction between the locking means and the locking surface of the driving ram is relatively high, so that the lifting of the locking means is relatively stiff. Furthermore, the material wear is quite high due to the sliding friction under surface pressure.
- the object of the present invention is therefore to develop a tacker of the aforementioned type, which avoids the aforementioned disadvantages.
- the blocking means is designed as rotatably mounted on the locking device and rollable on the catch stop wheel element.
- the frictional resistance when releasing the locking element can be considerably reduced by the locking stop, since instead of the sliding friction now much lower rolling friction occurs because the wheel element rolls with its locking surface on the catch block.
- the opening of the locking element is now much smoother and thus requires less energy. Furthermore, the wear is reduced.
- the wheel element is mounted on a rotation axis on a support element, which is pivotable about a pivot axis, wherein the axis of rotation of the wheel element is parallel to the axis of the pivot axis.
- the wheel member is designed as a rolling bearing, whereby the rolling friction can be minimized.
- a rolling bearing is also available as a low-cost standard part, so that no increased additional costs.
- the contact of the wheel element with the catch stop (in the blocking position) is spaced from the closing direction of the carrier element by a point of the catch stop closest to the pivot axis.
- the blocking element acts self-closing, since it experiences a force acting in the closing direction by the force of the tensioned drive spring.
- FIGS. 1 to 3 illustrated tackle 10 has a housing 11 and disposed therein, generally designated 30 drive arrangement for a drive-in ram 13 which is guided in a guide 12 displaceable.
- the drive-in ram 13 has a drive-in section 14 for a fastening element 60 and a head section 15.
- end of the guide 12 closes a coaxial with this extending bolt guide 17 to this.
- a fastener magazine 61 is arranged in the fasteners 60 are stored.
- the drive arrangement 30 includes a drive spring element 31 which is supported with one end at a support point 36 indirectly on the housing 11 and which engages with another end on the head portion 15 of the drive rod 13.
- the drive spring element 31 is z. B. a composite or steel spring and z. B. formed as a helical spring.
- a total of 50 designated locking device having a rotatably mounted on a support member 51 locking means in the form of a wheel member 59 which in a locking position 54 (see Fig. 1 ) engages with a blocking surface 59 on a locking stop 53 on a projection 58 of the driving tappet 13 and holds it against the force of the drive spring means 31.
- the blocking surface 59 is circumferentially disposed on the wheel member 49, the z. B. is designed as a rolling bearing (see in particular Fig. 3 ).
- the support member 51 is formed as a pivoting arm and mounted on a shaft 48 of a servomotor 52, via which it is in a Fig. 2 apparent release position 55 can be transferred, as will be described below.
- the shaft 48 defines a pivot axis A around which the carrier element 51 is pivotable.
- An axis of rotation D of the wheel member 49 is axially parallel to the pivot axis A, in order to avoid any friction losses other than the occurring rolling friction.
- the servo motor 52 is connected via an electrical first control line 56 to a control unit 23, via which it is controlled.
- the tacker 10 further includes a handle 20 on which a trigger switch 19 is arranged to trigger a driving operation with the tacker 10.
- a handle 20 on which a trigger switch 19 is arranged to trigger a driving operation with the tacker 10.
- the handle 20 is also still a total designated 21 power supply arranged, via which the tacker 10 is supplied with electrical energy.
- the power supply 21 includes at least one accumulator.
- the power supply 21 is connected via electrical supply lines 24 both to the control unit 23 and to the trigger switch 19.
- the control unit 23 is further connected via a switch line 57 to the trigger switch 19.
- a switching means 29 is arranged, which is electrically connected via a switching means 28 to the control unit 23.
- the switching means 29 sends an electrical signal to the control unit 23 as soon as the tacker 10 is pressed against a workpiece U, as shown Fig. 2 can be seen, and so ensures that the tacker 10 can only be triggered when it has been properly pressed against a workpiece U.
- This tensioning device 70 comprises a motor 71 via which a drive roller 72 can be driven.
- the motor 71 is electrically connected to the control unit 23 via a second control line 74 and can be put into operation via this, z. B. when the driving ram 13 is in its lying in the driving direction 27 end position or when the tacker is lifted off the ground again.
- the motor 71 has a Output means 75, such as a driven gear, which can be coupled to the drive roller 72.
- the drive roller 72 is rotatably mounted on a longitudinally adjustable actuating arm 78 of a solenoid 76 designed as a solenoid.
- the adjusting means 76 is connected via an actuating line 77 to the control unit 23. In operation, the drive roller 72 rotates in the direction of the arrow 73 indicated by dashed lines.
- the control unit 23 first ensures that the drive-in ram 13 is in its off Fig. 1 apparent clamping position 22 is located. If this is not the case, then the drive roller 72 is moved up by the adjusting means 76 to the output means 75, which has already been rotated via the motor 71, and is engaged therewith. At the same time, the drive roller 72 engages the drive-in ram 13 so that it is offset in the direction of the drive arrangement 30 via the drive roller 72 rotating in the direction of the arrow 73. In this case, the drive spring element 31 of the drive assembly 30 is tensioned.
- the motor 71 can be turned off after the engagement of the wheel member 49 on the locking stop 53 via the control unit 23 and the actuating means 76 drives the drive roller 72, also controlled by the control unit 23, from its engaged position on the output means 75 and the driving ram 13 in its disengaged Position (cf. Fig. 2 ).
- the control unit 23 is first set in Setzrschaft via the switching means 29. If the trigger switch 19 is then actuated by an operator, then the locking device 50 is displaced into its release position 55 via the control unit 23, wherein the carrier element 51 with the wheel element 49 is lifted off the drive ram 13 via the servomotor 52. In this case, the wheel member 49 rolls with its locking surface 59 on the locking stop 53 on the projection 58 under a low rolling resistance.
- the blocking surface 59 does not have to be continuous, but can also be discontinuous, z. B. be designed as a structured or profiled surface.
- the drive-in ram 13 is then moved via the drive spring element 31 of the drive arrangement 30 in the drive-in direction 27, wherein a fastening element 60 is driven into the workpiece U.
- the clamping device 70 is activated via the control unit 23 at the end of a drive-in operation when the drive-in device 10 is lifted off the workpiece U again.
- the switching means 29 supplies to a signal to the control unit 23.
- About the tensioning device 70 of the driving ram 13 is driven in the manner already described against the drive spring element 31 of the drive assembly 30 and the drive spring member 31 while re-tensioned until the support member 51 with the wheel member 49 again can occur in its blocking position 54 on the locking stop 53 on Eintreibstössel 13.

Abstract
Description
Die vorliegende Erfindung betrifft ein handgeführtes Eintreibgerät der im Oberbegriff von Patentanspruch 1 genannten Art. Derartige handgeführte Eintreibgeräte verfügen über einen versetzbar geführten Eintreibstössel über den Befestigungselemente in einen Untergrund eintreibbar sind.The present invention relates to a hand-held tacker of the type mentioned in the preamble of claim 1. Such hand-held tackers have a displaceably guided Eintreibstössel about the fasteners are driven into a ground.
Als Antriebsquelle für den Eintreibstössel dient dabei eine mechanische Antriebsfeder, die über einen Spannmechanismus spannbar ist. Von Vorteil ist dabei, dass die mechanische Antriebsfeder kostengünstig ist, wodurch ein derartiges Eintreibgerät preiswert herzustellen ist. Da der Spannvorgang insbesondere bei starken Antriebsfedern einige Zehn- bis einige Hundert Millisekunden dauern kann, ist es von Vorteil, wenn der Spannvorgang bereits vor einer Betätigung des Auslöse- oder Triggerschalters des Eintreibgerätes vollzogen wurde. Es ist dann ferner notwendig, dass die Antriebsfeder über eine Sperreinrichtung direkt oder indirekt über ein weiteres Element, wie z. B. den Eintreibstössel, in ihrer gespannten Stellung fixiert wird bis das Eintreibgerät ausgelöst wird.The drive source for the drive ram is a mechanical drive spring, which can be tensioned via a clamping mechanism. The advantage here is that the mechanical drive spring is inexpensive, whereby such a tacker is inexpensive to manufacture. Since the tensioning process can take several tens to a few hundred milliseconds, especially with strong drive springs, it is advantageous if the tensioning process has already been completed before an actuation of the triggering or trigger switch of the tacking device. It is then further necessary that the drive spring via a locking device directly or indirectly via another element, such. As the drive ram is fixed in its cocked position until the tacker is triggered.
Aus der
Von Nachteil bei dem bekannten Eintreibgerät ist, dass die Gleitreibung zwischen dem Sperrmittel und der Sperrfläche des Eintreibstössels relativ hoch ist, so dass das Ausheben des Sperrmittels relativ schwergängig ist. Ferner ist der Materialverschleiss durch das Gleitreiben unter Flächenpressung recht hoch.A disadvantage of the known tacker is that the sliding friction between the locking means and the locking surface of the driving ram is relatively high, so that the lifting of the locking means is relatively stiff. Furthermore, the material wear is quite high due to the sliding friction under surface pressure.
Die Aufgabe der vorliegenden Erfindung liegt daher darin, ein Eintreibgerät der vorgenannten Art zu entwickeln, das die vorgenannten Nachteile vermeidet.The object of the present invention is therefore to develop a tacker of the aforementioned type, which avoids the aforementioned disadvantages.
Diese Aufgabe wird erfindungsgemäss durch die in Anspruch 1 genannten Massnahmen gelöst. Demnach ist das Sperrmittel als drehbar an der Sperreinrichtung angeordnetes und am Sperranschlag abrollbares Radelement ausgebildet. Hierdurch kann der Reibungswiderstand beim Lösen des Sperrelements von dem Sperranschlag erheblich vermindert werden, da anstelle der Gleitreibung nun die viel geringere Rollreibung auftritt, da das Radelement mit seiner Sperrfläche auf dem Sperranschlag abrollt. Das Öffnen des Sperrelements ist nun viel leichtgängiger und benötigt damit auch weniger Energie. Ferner ist der Verschleiss reduziert.This object is achieved according to the invention by the measures mentioned in claim 1. Accordingly, the blocking means is designed as rotatably mounted on the locking device and rollable on the catch stop wheel element. As a result, the frictional resistance when releasing the locking element can be considerably reduced by the locking stop, since instead of the sliding friction now much lower rolling friction occurs because the wheel element rolls with its locking surface on the catch block. The opening of the locking element is now much smoother and thus requires less energy. Furthermore, the wear is reduced.
Vorteilhaft ist das Radelement an einer Drehachse an einem Trägerelement gelagert, das um eine Schwenkachse schwenkbar ist, wobei die Drehachse des Radelements achsparallel zu der Schwenkachse ist. Hierdurch werden über die auftretende Rollreibung hinausgehende weitere Reibungsverluste vermieden.Advantageously, the wheel element is mounted on a rotation axis on a support element, which is pivotable about a pivot axis, wherein the axis of rotation of the wheel element is parallel to the axis of the pivot axis. As a result, beyond the occurring rolling friction additional friction losses are avoided.
Günstigerweise ist das Radelement als Wälzlager ausgebildet, wodurch die Rollreibung minimiert werden kann. Ein derartiges Wälzlager ist ausserdem als kostengünstiges Standard-Teil erhältlich, so dass keine erhöhten Zusatzkosten entstehen.Conveniently, the wheel member is designed as a rolling bearing, whereby the rolling friction can be minimized. Such a rolling bearing is also available as a low-cost standard part, so that no increased additional costs.
Von Vorteil ist es weiterhin, wenn der Kontakt des Radelements mit dem Sperranschlag (in der Sperrstellung) entgegen der Schliessrichtung des Trägerelements beabstandet von einem der Schwenkachse nahesten Punkt des Sperranschlags ist. Hierdurch wirkt das Sperrelement selbstschliessend, da es durch die Kraft der gespannten Antriebsfeder ein in Schliessrichtung wirkendes Drehmoment erfährt.It is furthermore advantageous if the contact of the wheel element with the catch stop (in the blocking position) is spaced from the closing direction of the carrier element by a point of the catch stop closest to the pivot axis. As a result, the blocking element acts self-closing, since it experiences a force acting in the closing direction by the force of the tensioned drive spring.
