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.
  • 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 element 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 at an unwanted acceleration of the tacker, z. B. if this falls from an elevated position to a relatively lower position, the locking device could be inadvertently transferred to its release position.
  • the object of the present invention is therefore to develop a tacker of the aforementioned type, which avoids the aforementioned disadvantages.
  • an independent of the trigger switch mechanical blocking device for the locking device is provided on the tacker, which is switchable between an active position and a passive position, the locking device locked in the active position of the mechanical locking device in its blocking position and in the passive position of the mechanical locking device in their release order is transferable.
  • the mechanical blocking device has at least one blocking means, which is coupled to a mechanical contact pressure sensor, wherein the blocking device has a counter element which can be blocked by the blocking means.
  • the mechanical blocking device has at least one blocking means, which is coupled to a mechanical contact pressure sensor, wherein the blocking device has a counter element which can be blocked by the blocking means.
  • the mechanical blocking device has at least one blocking means which is coupled to a mechanical detection means for a current source, wherein the blocking device has a counter element which can be blocked by the blocking means.
  • a power source such. B. a rechargeable battery or a battery, is present in the appropriate recording on Eintreibêt. So it can not be triggered driving when no power source is present in the recording.
  • the mechanical blocking device is designed so that at least one of the blocking means is in the active position of the mechanical blocking device in a position blocking the associated counter-element. In order to transfer the mechanical blocking device in the passive position, so that the locking device on the trigger switch can be transferred to the release position, so all blocking must be in their the locking device or the counter-elements belonging to this non-blocking position method.
  • the at least one blocking element is acted upon by a spring element in the direction of its blocking the associated counter-element position, so that the mechanical blocking device is always automatically put back into its active position, z. B. when the tacker is lifted from a workpiece or when the power source or the battery is removed from the recording.
  • 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 80 and a head section 15.
  • end of the guide 12 closes a coaxial with this extending bolt guide 17 to this.
  • a fastener magazine 81 is arranged in the fasteners 80 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 may, for. B. be designed as a composite spring or steel spring and is z. B. formed as a helical spring.
  • a blocking element 51 such.
  • B. has a pawl in a blocking position 54 (see Fig. 1 and 2 ) engages with a locking member 59 formed as a pin on a locking surface 53 on a projection 58 of the driving ram 13 and this holds against the force of the drive spring means 31.
  • the blocking element 51 is mounted on a shaft 49 of a servomotor 52 and is via the servomotor 52 in a Fig. 3 apparent release position 55 can be converted (dashed line blocking element 51), as will be described below.
  • the servomotor 52 is connected via an electrical first control line 56 to a control unit 23.
  • a total of 60 designated mechanical blocking device is arranged, which is independent of a trigger switch of the tacker 10 and which has a first blocking means 62 and a second blocking means 65, via which the locking device 50 can be locked in its blocking position 54.
  • the mechanical blocking device 60 can be switched back and forth between an active position 68 and a passive position 69, the mechanical blocking device 60 locking the blocking device 50 in its blocking position 54 in its active position 68 and the blocking device 50 being in the passive position 69 of the mechanical blocking device 60 in its blocking position Release position 55 can be transferred.
  • the first blocking means 62 of the mechanical blocking device 60 is coupled to a mechanical contact pressure sensor 41 which detects the pressing of the tacker 10 with its mouth 82 against a workpiece U.
  • the Anpressconnectler 41 is designed as an actuating rod and displaceably guided on the pin guide 17 and in the housing 11 of the tacker 10. In the non-pressed state of the tacker 10, a free end of the Anpress catalystlers 41 extends beyond the mouth 82 of the tacker 10 (see Fig. 1 ).
  • the Anpressconnectler 41 is acted upon via a first spring element 66 in the direction of its mouth 82 superior position elastically.
  • the first blocking means 62 at the other end of the Anpressbutlers 41 is in this non-pressed state of the tacker 10 a first counter-element 61 of the locking member 51 directly opposite and thereby blocks a pivoting of the locking member 51 in the release position 55th
  • the second blocking means 65 of the mechanical blocking device 60 is coupled to a mechanical detection means 63, which detects the presence of a current source 21, such. B. a rechargeable battery or a battery pack, detected in a receptacle 18 of the tacker 10.
  • the detection means 63 is also designed as an actuating rod and displaceably guided in the housing 11 of the tacker 10. If there is no current source 21 in the receptacle 18, a free end of the detection means 63 protrudes into the receptacle 18 (see Fig. 1 ).
  • the detection means 63 is acted upon by a second spring element 67 in the direction of its projecting into the receptacle 18 position elastically.
  • the second blocking means 65 at the other end of the detection means 63 is in this state, a second counter-element 64 of the locking member 51 directly opposite and thereby blocks a pivoting of the locking member 51 in the release position 55th
  • the blocking device 60 is always in its active position 68 when at least one of its blocking means 62, 65 blocks the blocking element 51 of the blocking device 50 and prevents the blocking element 51 from pivoting into the release position 55.
  • 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.
  • the receptacle 18 for those with 21 (see Fig. 2 ) designated mains-independent power source, via which the tacker 10 is supplied with electrical energy.
  • the current source 21 includes at least one accumulator, which in Fig. 2 is inserted in the receptacle 18.
  • the current source 21 or the at least one accumulator is connected via a contact element 16 to the receptacle 18 and via an electrical supply line 24 to the control unit 23.
  • the control unit 23 is further connected via a switch line 57 to the trigger switch 19.
  • the Anpressiqueler 41 cooperates via a switching element 42 with an electrical switching means 29 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 thus ensures that a setting process on the control unit 23 of the tacker 10 can be triggered only when the tacker 10 has been properly pressed against a workpiece U.
  • This tensioning device 70 comprises a motor 71 via a drive roller 72 is drivable.
  • 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 an output means 75, such as a driven wheel, 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.
  • the drive roller 72 is coupled to the output means 75 and offset by this in the direction indicated by dashed lines arrow 73 in rotational movement.
  • the drive roller 72 is then in frictional contact with it.
  • Another suitable embodiment of the clamping device 70 is of course possible.
  • the control unit 23 first ensures that the drive-in ram 13 is in its off Fig. 1 apparent starting 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.
  • Fig. 2 is a current source 21 in the receptacle 18, so that the detection means 63 has been displaced and coupled to the detection means 63 second blocking means 65 from his Fig. 1 apparent position relative to the second counter-element 64 of the locking element 51 has been moved away.
  • the control unit 23 is first set in Setzrschaft via the switching means 29.
  • the Anpress catalyst 41 is offset to the tacker 10 out, so that coupled to the Anpressterminler 41 first blocking agent 62 from his out Fig. 1 apparent position relative to the first counter-element 61 of the locking member 51 is moved away.
  • the blocking device 60 is now in its passive position (as well as in Fig. 3 can be clearly seen), in which the blocking element 51 can be transferred to its release position.
  • the locking device 50 is displaced into its release position 55 via the control unit 23, the blocking element 51 being lifted off the blocking surface 53 on the driving ram 13 via the servomotor 52.
  • 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 80 is driven into the workpiece U.
  • the tensioning device 70 is activated via the control unit 23, preferably before the tacker 10 is lifted off the workpiece U again.
  • 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 tensioned again until the pawl 51 can again come into its blocking position 54 on the locking surface 53 on the drive tappet 13.
  • the blocking element 51 may be spring-loaded in the direction of the driving ram 13.
