Definitions

  • the invention relates to a power-driven wrapping device according to the preamble of the main claim.
  • Wrapping devices that work with a so-called free shot protection have already become known. This free shot protection is intended to prevent stapling agents from being fired without the wrapping device being seated on a workpiece.
  • Either these wrapping devices have a safety button at a suitable point or a fuse attached to the device nose. In both cases, the wrapping machine can only be triggered if the fuse has previously been deactivated. An additional safety lever must also be operated.
  • the level of security it provides depends on the operator and is only as great as human reliability. Securing fails when people fail.
  • the fuse connected to the nose of the device does not require an additional operating handle. When changing quickly from one point of impact for one staple to another, however constantly let go of the handle for triggering a driver blow and operated again. This necessary operation is time-consuming and tiring, especially when speed and less precise positioning of the fastener is important.
  • the wrapping device according to the invention with the characterizing features of the main claim has the advantage of offering a free-shot protection which also allows the release handle to be held in the release position and to trigger the blow by attaching the nose to the workpiece.
  • a number of stapling agents should be able to be set quickly and effortlessly if the stapling agent does not need to be positioned very precisely.
  • the interaction according to the invention of the button actuated when the impact device is pressed onto the workpiece and the handle for triggering a driver impact means that the last actuated of the two components can trigger the driver impact. It is no longer important to first place the wrapping device on the workpiece and then to actuate the handle to release it. This order is possible but not mandatory.
  • FIG. 1 An embodiment of the subject of the invention is shown in the drawing and explained in more detail in the following description.
  • the figure shows a partial longitudinal section through a wrapping device designed according to the invention.
  • a wrapping device 1 contains in a housing 2 a magnet coil 3 for a diving magnet 4, a circuit board 5 with switching electronics and a driver 6.
  • a driver 7 connects the diving magnet 4 with the driver 6 so that the diving magnet 4 drives the driver 6 in the driving direction can.
  • a return spring 8 is pushed onto the immersion magnet 4 and is supported on the one hand on an end face of the magnet coil 3 on the driver 7.
  • a guide rod 9 gives the immersion magnet 4 safe guidance. For this purpose, it is held in bearings 10 and 11 in housing 2.
  • the lower end of the driver 6 in the illustration according to the figure can be moved in a channel 12 in the head 13 of a staple magazine 14.
  • a nose 15 of the head 13 projects beyond the underside of the tacking magazine 14.
  • a tab 16 on the tacking magazine 14 has an elongated hole 17.
  • the tacking magazine 14 With this elongated hole 17, the tacking magazine 14 is hung over a housing-side hub 18, which at the same time has a threaded hole 19.
  • One of the screws holding the two shells of the housing 2 of the impactor 1 together can be screwed into this threaded hole 19.
  • These screws are marked with 20 and in four other places of the Housing 2 shown in the figure.
  • the stapling agent magazine 14 At its end facing away from the head 13, the stapling agent magazine 14 has a tab 21 which engages in a housing pocket 22 and together with it can form a joint.
  • the staple magazine 14 can be pivoted about this joint, as indicated by an arrow 23.
  • a helical spring 25 is inserted, the end protruding from the recess 24 is supported on the magazine magazine 14. So that the helical spring 25 cannot slip on the support surface, a nose 26 is bent out of the housing of the tacking magazine 14. It engages in the interior of the coil spring 25.
  • the prestressed coil spring 25 thus always seeks to attach the magazine 14 with the upper edge of the elongated hole 17 to the hub 18.
  • a lever arm 27 of an angle lever 28 also bears against the same surface of the stapling magazine 14 against which the coil spring 25 bears. This angle lever 28 is supported on a bolt 29 in the housing 2. It has a bent end 30.
  • the lever arm 27 emerges from this housing 2 through a corresponding opening in the housing 2.
  • the angle lever 28 can, as the figure shows, be moved to the left when the tacking magazine 14 is pressed against the housing 2.
  • This angle lever 28 there is an end 31 of a transmission member 32.
  • the transmission member 32 is articulated to a handle 33 for triggering a driver blow.
  • This handle 33 in turn is pivotally supported in a trough 34 in the housing 2. It is supported by a helical spring 35 in a bearing 36 fixed to the housing. In the example case this is Bearing 36 is part of a receptacle 37 for an electrical component 38.
  • a device 39 for fixing a power cable 40 which is inserted into the housing 2 through an opening 41 in the latter.
  • the end of this power cable 40 is passed through a bridge 42 from the handle part of the housing 2 to the lower part of the housing 2 and connected to the circuit board 5 with its individual wires.
  • the board 5 carries, in addition to terminals 43 and 44, an axis 45 for an adjusting button 46. With it, the strength of the driver's stroke can be adjusted. Details of this are unimportant for understanding the invention.
  • the circuit board 5 also carries a trigger 47, with which the supply circuit for the magnet coil 3 can be closed. For this, insulated wires 48 and 49 are led from the circuit board 5 to the magnetic coil 3.
  • the trigger 47 has a nose 50 with an inclined contact surface 51.
  • a first projection 52 is intended to interact with the nose 50 of the trigger 47 and has one for Starting slope 51 matching starting slope.
  • the second projection 53 is opposed to the bent end 30 of the angle lever 28.
  • a leaf spring 55 is inserted, the free end resiliently pressing against the transmission member 32. The leaf spring 55 always seeks to keep the transmission member 32 with its end 31 away from the trigger 47.
  • the stapling agent magazine 14 is loaded with stapling means in a known manner and the power cable 40 connected to the network.
  • the nose 15 of the staple magazine 14 is pressed onto a workpiece and the force of the coil spring 25 is overcome with this pressing force.
  • the staple magazine 14 lies against the lower edge 56 of the housing 2.
  • the angle lever 28 is pivoted counterclockwise around its bolt 29.
  • the end 30 of the angle lever 28 presses the end 31 of the transmission member 32 so far towards the trigger 47 that the first projection 52 comes to rest with its contact surface in front of the chamfer 51 of the nose 50 of the trigger 47.
  • the transmission member 32 is pulled in the direction of an arrow 57 with this handle 33.
  • the second projection 53 runs at the end 31 of the transmission member 32 at the end 30 of the angle lever 28, while the first projection 52 of the end 31 takes the trigger 47 along with the nose 50. So that the trigger 47 is moved to the position in which it applies voltage to the solenoid 3.
  • the helical spring 25 presses the tacking magazine 14 away from the housing 2, whereby it is pivoted about the joint 21/22.
  • the leaf spring 55 presses on the transmission member 32 on the angle lever 28 so that it rotates in a clockwise direction with its lever arm 27 on the stapling agent magazine following its actuating movement.
  • the end 31 of the transmission member 32 also withdraws from the release 47 to such an extent that it opens the supply circuit for the solenoid again.
  • the stapling agent magazine 14 presses the transfer member 32 against the trigger 47 again via the angle lever 28 and brings it back into the switched-on position.
  • the solenoid 3 causes a new driver blow. In this way, a number of stapling agents can be set in quick succession. The operator need not let go of the handle 33.
