Definitions

  • the invention relates to a power-driven wrapping device according to the preamble of the main claim.
  • Wrapping devices of this type also called staple guns, are known, for example, from DE-GM 83 03 460.
  • staple guns are known, for example, from DE-GM 83 03 460.
  • it is also customary to design interchangeable front plates in order, for example, to be able to use staples of different back thickness. Staples with a narrow spine are useful if you don't want the staples to be visible. This means that more shots can be carried out per magazine fill. Staples with a wide back are advantageous if lightly tearing materials are to be attached and if a greater pull-out force, for example in soft ground, is also to be achieved.
  • the replacement of the front panels and magazines and the provision of these differently designed parts is complex. In addition, this method runs the risk of front plates and magazine parts being mixed up and replacement parts being lost. This leads to malfunctions. Finally, tools are required to replace the front panels and magazines or magazine parts.
  • the wrapping device according to the invention with the characterizing features of the main claim has the advantage that the different fastening cases can be managed with one type of fastener by optionally one or at least two stapling means can be shot at the same time. Due to the adjustability of the stop for the stapling agent package, the shape of the stop and the cross section of the driver which deviates from the cross section of the shot channel beyond the fit tolerance, the shot channel can be narrowed by the stop, e.g. a width for two staples to a width for a staple, without this affecting the mobility of the driver in the firing channel.
  • the measures listed in the subclaims permit advantageous developments and improvements of the wrapping device specified in the main claim. It is particularly advantageous to design the driver with two tongues, by means of which it is even possible to make a second stroke on a tack that is not fully wrapped on the first stroke. By means of the specified measure, the package of tacking agents can be pushed back so far by means of the stop that there is no more tacking agent in the firing channel. However, the mobility of the driver is not affected.
  • FIG. 1 shows a side view of a tacker designed according to the invention, partially in section
  • FIG. 2 shows a partial view of a tacker according to the invention in accordance with a first embodiment, partially in section

  • Figure 5 shows a view of a driver according to the invention in the embodiment of Figure 4
  • Figure 6 shows a partial view like Figure 2 of a third embodiment in section
  • Figure 7 shows a partial view like Figure 2 of a fourth embodiment
  • Figure 8a and b a fifth embodiment in a sectional partial view and a side view of it, in the setting for two-clamp shot, Figure 9a and b, the execution and representation as in Figure 8a and b, in the setting for a single-clamp shot
  • Figure 10a and b the design and illustration as in FIGS. 8a and b, only with a modified design of the driver

  • FIG. 13 shows an expanded embodiment of the embodiment according to FIG. 11 in a side view
  • FIG. 14 shows a seventh embodiment of the invention in a simplified sectional view.
  • the tacker 1 shown in Figure 1 has a longitudinally divided housing made of two shells. This housing forms one Handle 2 with an inlet opening for the electrical supply line 3 and an actuating handle 4.
  • the handle located on the top of the tacker 1 is connected to the lower part 6 of the tacker via a web 5.
  • This tacker base 6 receives the electrical or electronic switching elements that are required to trigger the tacker and to adjust its strength.
  • the line 3 is guided through the web 5 to these switching elements.
  • an actuator 7 is used to set the impact strength of the driver for the staples.
  • a magazine 8 is fastened to the lower part 6 of the tacker and can hold a package of tacking agents 9.
  • This tack package 9 is urged by a slide 10 to stop against a front plate 11. He himself is driven by a magazine spring 12. Your abutment finds this magazine spring 12 on a hook 13.
  • the magazine spring 12 is designed as a tension spring and deflected in its direction of action via a bolt 14. In this way, the necessary spring length is obtained for a long spring travel corresponding to the magazine travel, by means of which a pressure that is as constant as possible is to be exerted on the staple package.
  • the magazine 8 finally forms a mouthpiece 16 with a part 15. The magazine 8 is inserted in an articulated manner into a pocket 18 of the housing of the stapler 1 by means of a bent edge 17.
  • the magazine 8 At the mouth end of the magazine 8 this is provided with a tab 19 which has an elongated hole 20. With this elongated hole 20, the magazine 8 is suspended over a housing-side hub 21, which at the same time has a threaded hole 22. In this threaded hole 22 one of the screws can be screwed, the two shells of the housing of the tacker 1. These screws are designated by 23 and are shown at four further locations in the housing in FIG. 1.
  • the front plate 11 is preceded by an adjusting device 24.
  • This adjusting device consists of a slide 25 with a stop body 26 which has a run-on slope 27.
  • the stop body 26 is fixedly connected to the slide 25 by a rivet 28.
  • a spring band 29 is also fastened to the slide 25 with the rivet 28.
  • the free end of the spring band 29 carries a locking pin 30 with a handle 31.
  • the locking pin 30 passes through a bore 32 in the slider 25 and can engage in one of two locking bores 33 in the front plate 11 of the tacker 1. With this locking device, the slider 25 can be set in two different positions. In the upper position of the slider 25 shown in FIG. 2, the run-on slope 27 offers the staple 9 a first stop.
  • the front plate 11 and a rear plate 34 together form a firing channel 35.
  • a driver 36 is guided, which has a U-shaped cross section.
  • the stop body 26 can engage between the legs 37 of this U.
  • two staples 38 of the staple 9 are in the firing channel.
  • the pushing-down driver 36 can separate these two staples 38 from the staple package and drive them into a workpiece 39 through the shot channel 35.
  • the foremost staple 38 is gripped by the legs 37 in the region of its staple legs, while the second staple 38 is struck by the driver end face over its entire width. So the clean separation of the Staples 38 and the driving of both staples into the workpiece 39 is guaranteed.
  • the slide 25 with all the parts attached to it can be pulled down by means of this handle 31. If the locking pin 30 engages in the lower of the locking bores 33, the second working position of the slide 25 is fixed. On the way there, the stop body 26 has also slid downward in a guide slot 40 in the front plate 11. His run-up slope 27 has pushed the staple 9 out of the firing channel 35 by the thickness of a staple 38. The driver 36 pushing downwards can now only separate one staple from the staple 9 and drive it into the workpiece 39.
  • FIG. 4 additionally shows a drive member 41 for a driver 42.
  • This driver 42 is not U-shaped in cross-section but is designed as a fork with two fork legs 43.
  • a slider 44 carries a spring band 45 and with this the locking pin 30 with its handle 31.
  • the slide 44 also has a bore 32 through which the locking pin 30 can reach.
  • the locking holes 33 are three instead of two.
  • a stop body 46 is connected to the slide 44 by the rivet 28.
  • this stop body 46 In addition to the guide slot 40 in the front plate 11, this stop body 46 also engages in the slot 47 between the fork legs 43. A first run-up slope 48 on the stop body 46 is followed by a non-rising stop surface 49 and this in turn is followed by a second run-up slope 50.
  • a first run-up slope 48 on the stop body 46 is followed by a non-rising stop surface 49 and this in turn is followed by a second run-up slope 50.
  • the stop surface 49 lies in one plane with the parting plane the two staples 38 in the firing channel 35.
  • the downward-pushing driver 42 strikes the two staples 38 with its fork legs 43, separates them from the staple package 9 and knocks them into the workpiece 39.
  • the slide 44 is pulled down in the same way as the slide 25 in the exemplary embodiment according to FIGS. 2 and 3 and latched into the next of the locking bores 33.
  • the stop surface 49 now offers the tacking package 9 the stop. This has been displaced from the firing channel 35 by the thickness of a staple 38. So only one staple 38 can be driven.
  • the tacking agent package is 9 completely displaced from the firing channel 35.
  • the driver 42 can now strike downwards on both sides of the stop body 46 with its fork legs 43 and thus a tack that is not fully driven in on the first impact, in this case one or two staples 38, can fully impact the workpiece 39.
  • the function of the stapler 1 according to the exemplary embodiment is shown in FIG Figures 2 and 3 has thus been expanded to include an essential additional function.
  • the front plate is firmly connected to the magazine 8. It was given the reference number 51.
  • a guide plate 52 which is blasted into the magazine 8, takes over the guiding of the adjustable stop.
  • the adjustable stop is formed here by a slide 53.
  • This slide 53 is connected via a clutch slide 54 to an actuating slide 55.
  • the clutch slide 54 is placed under the action of a spring 56. This spring 56 always tries to move it towards the mouthpiece 16. In the upper position of the actuating slide 55, the spring 56 is therefore tensioned.
  • a nose 57 within the guide for the actuating slide 55 is assigned to a corresponding projection 58 at the upper end of the actuating slide 55 and serves to hold the actuating slide 55 in the upper position against the force of the spring 56.
  • the actuating slide 55 is connected to the coupling slide 54 via a pin 59.
  • the bearing opening 60 serving this connection allows the actuating slide 55 to be tilted, with which the latching of the projection 58 behind the nose 57 or the latching out of this latching connection is made possible.
  • a knurled handle 61 facilitates the operation of the actuating slide 55.
  • An oblique stop surface 62 at the lower end of the slide 53 has the same function as the stop slope 27 in the exemplary embodiment according to FIGS. 2 and 3.
  • the staple gun is simultaneously prepared for the hammering in of two staples 38.
  • the driver 36 thus comes into effect with its full, U-shaped end face.
  • the operator presses on the knurled handle 61 of the actuating slide 55. This then tilts with its pin 59 in the bearing opening 60 in such a way that the projection 58 comes out of engagement with the nose 57 which had held it until then.
  • the slide 53 to 55 are driven down until the actuating slide 55 has reached its lower end position.
  • the contact surface 62 has displaced the staple package 9 so far from the weft channel 35 that only one staple 38 protrudes into this weft channel 38.
  • the actuating slide 55 must be gripped on the knurled handle 61 and returned to its starting position against the action of the spring 56.
  • the stapling agent package 9 bears against a front plate 63 under the action of the slide 10 and the magazine spring 12 driving it.
  • This front plate 63 forms, together with a rear plate 64, a firing channel 65.
  • a driver consisting of two blades 66 and 67 is guided in this firing channel 65.
  • the thickness of one of the driver blades corresponds the thickness of a staple 38, two of which are located one behind the other in the firing channel 65.
  • a cap 68 overlaps a slot 69 in the front plate 63.
  • a U-shaped angle piece 70 is fastened on the front plate 63 within this cap 68 and around the slot 69. Different shaped guide slots are punched into the U-legs of the angle piece 70.
  • An actuating slide 73 is mounted in these slots. Once it is guided with a bolt 74 in the straight slot 71, on the other hand a guide pin 75 connected to it engages through the slot-shaped slots 72.
  • the slot-shaped slots 72 have three locking points into which the guide pin 75 can snap.
  • a leaf spring 76 ensures that the guide pin 75 remains in the selected locking position even when no staple 9 is inserted, the front staple 38 presses against a stop surface 77 of the actuating slide 73.
  • a bolt 78 protrudes through an opening 79 in the cap 68 and serves as an actuator.
  • the abutment surface 77 leaves two clips in the firing channel 65, which can be driven in simultaneously.
  • the middle detent position defines a position of the stop surface 77 in which there is only one clip in the firing channel 65.
  • the package of tacking agents is then supported under the action of the magazine spring 12 on an inclined catch surface 68.2 of the catcher 68.1 and thus also remains outside the firing channel 65. A lookup is thus possible. If the blade 67 of the driver 66/67 is also fork-shaped, the third latching option in the slot-shaped slots 72 can be selected such that it offers the additional function of looking up as described for FIGS. 4 and 6 even without the catcher 68.1.
  • the exemplary embodiment according to FIG. 8 shows a further possible variant with a two-blade driver 80/81.
  • a guide plate 84 is blown between a front plate 82 and a rear plate 83.
  • a shot channel 85 is formed between the guide plate 84 and the rear plate 83.
  • An adjusting slide 86 guided between the front plate 82 and the guide plate 84 is as thick as a staple 38. Its lower face 87 is chamfered.
  • a U-shaped stop 88 is arranged beneath the adjusting slide 86, bearing against the inner surface of the front plate 82. The U-legs of this stop 88 pass through corresponding slots in the guide plate 82. They offer the stapling agent package 9 a stop in the region of the legs of the staples 39.
  • a spring tongue 89 which has been removed from the stop 88 is supported on the guide plate and thus urges the stop 88 always on the inner surface of the front plate 82.
  • the U-legs 90 and 91, with their end faces 92 provided as a stop, are flush with the surface of the guide plate 84 which faces the rear plate 83.
  • the upper ends of the U-legs 90 and 91 are widened in a funnel shape to a width greater than the width of the bracket.
  • the upper end 93 of the rear wall of the stop 88 is slightly retracted, so that the adjusting slide 86 together with its oblique face 87 can be passed well behind the stop 88.
  • Figure 8a shows the preparation for two-bracket operation.
  • the sheet 80 is designed as a fork with two legs resilient in the sheet plane.
  • Sheet 81 is full with a rectangular cross-section.
  • the driver 80/81 is pushed through the firing channel 85 and thereby drives two staples 38 into the workpiece 39.
  • the setting slide 86 is moved downward in the manner described for FIG. He squeezes in between the inner wall of the front plate 84 and the back of the stop 88.
  • the U-legs 90 and 91 of the stop 88 are pushed through the slots in the guide plate 84 and force the staple 9 by the thickness of a staple 38 out of the shot channel 85.
  • FIG. 9 shows this setting of this exemplary embodiment on single-clamp operation, with the legs 80 of the blade 80 springing in, which have already penetrated somewhat into the guide of the stop 88 between the U-legs 90 and 91.
  • Recesses 94 and 95 at the upper end of the sheets 80 and 81 according to FIG. 8b and a clamp 96 according to FIG. 9b show how the sheets 80 and 81 are held together.
  • the variant according to FIGS. 10a and b differs from that according to FIGS. 8 and 9 only in that the sheet 80 is designed as a two-sheet sheet 97/98.
  • FIGS. 11 and 12 show a further possible embodiment of the invention, in which the stop is adjusted with a slide which can be adjusted parallel to the feed movement of the staple package 9.
  • a Magazine 99 On a tacker housing 1 is a Magazine 99 attached.
  • the magazine 99 receives a staple 9, its slide 10 and its magazine spring 12. It forms a mouthpiece 100 with a front plate 101 and a rear plate 102. Both plates form a firing channel 103.
  • a U-shaped driver 104 is suitable for firing two staples 38 at the same time as the firing channel 103.
  • a slide 105 is connected between the magazine 99 and the housing of the tacker 1.
  • the slider 105 has a recess 106 which is assigned to the driver 104.
  • This recess 106 is also U-shaped in cross section, corresponding to the cross section of the driver 104. This recess thus offers a stop surface 107. This stop surface 107 projects downward from the slide 105 into the guide channel for the stapling agent package 9.
  • a handle 109 mounted in a web 108 is used to adjust the slide 105. This handle 109 is held by means of an annular groove 110 in this handle in which the two shells of the housing of the tacker 1 engage with their wall.
  • a bracket 111 is firmly connected to the magazine 99.
  • a collar 112 of the handle 109 engages in this bracket 111. This collar 112 can also be designed as a switch cam which is firmly connected to the handle 109.

  • the device is now ready for as many lookups as the operator deems necessary.
  • the exemplary embodiment according to FIGS. 11 and 12 has been expanded according to FIG.
  • Such a fuse is intended to ensure that a staple (staple or nail) can only be conveyed through the firing channel when the mouth of the firing channel is placed on a workpiece.
  • the mouthpiece 100 is here Touch slide 121 assigned, which is placed under the action of a spring 122.
  • This spring 122 always tries to hold the slide gate 121 in a position in which it projects beyond the end face of the mouthpiece 100.

  • a tongue 131 is sheared out of the front plate 128 and serves as an angle lever 132 as a bearing.
  • This angle lever 132 is located inside a U-shaped slide 133, from which a resilient tongue 134 is removed.
  • the resilient tongue 134 abuts a lever arm 135 of the angle lever 132 in every position of the slide 133.
  • the other lever arm 136 of the angle lever 132 with its contact surface 137 serves as a stop for the staple package 9.
  • the shape of the stop 139 and the driver 36 allows the choice between one-clamp operation and two-clamp operation . If the tacker set to two-clamp operation according to FIG. 14 is to be switched to a setting for one-clamp operation, then in a known manner the slider 133 moved down. The back 140 moves between the magazine jacket 138 and the contact surface 137 of the angle lever 132. Since the thickness of the back 140 corresponds to the thickness of a staple 38, one of these staples 38 is displaced from the firing channel 130. The desired switchability between one-clamp operation and two-clamp operation is also achieved here.
