Definitions

  • the invention relates to a nail driving device with a magazine for nails combined into straight strips or rows, which nails successively from the front end of a possibly inclined staggering of the nails, via a lateral inlet channel leading into an expulsion channel into a ready position for e.g. pneumatic expulsion can be pressed out of the expulsion channel.
  • a single nail strip can be received in the magazine, which consists of a number of staggered nails arranged one behind the other and connected to one another by means of lateral paper or plastic strips. Since the magazine must not exceed a certain length in order not to impair the handiness of the device, the magazine is capacity very limited. The nail strips therefore have to be replaced quite frequently, which makes working with such a device more difficult.
  • Nail driving devices are also known, the magazines of which have a drum shape and can hold up to 300 or more nails.
  • the nails must be connected with a strip of plastic material or one or more steel wires to form an endless strip and rolled up into a coil that can be inserted into the drum magazine of the device.
  • the coil magazines also have considerable disadvantages. Loaded with 300 or more nails, for example, they are quite heavy and not suitable for all users. The user does not have the option of inserting fewer nails into the magazine, since normally only a certain amount of coils are available.
  • Another disadvantage of the drum magazine is that reloading is only possible when the coil is completely used up. In practice, this has proven to be extremely disadvantageous.
  • the object of the present invention is therefore to develop a nail driving device of the generic type in such a way that it does not have the disadvantages previously described for drum magazines, and nevertheless has a larger magazine capacity.
  • the magazine is designed as a box magazine of a width for receiving two or more nail strips or rows side by side and that the nail strips or rows one after another perpendicular to the planes of the nail strips or rows in alignment with the inlet channel of the Ejection channel can be pressed.
  • Such a box magazine can also be loaded with up to 300 or more nails in the form of strips or rows, but it does not have to, since the total load is composed of comparatively short individual strips or rows, of which a more or less large number is in the box magazine can be used. If, for example, only a small number of nailings are to be carried out on a workpiece, it may even be sufficient to insert a single nail strip. The high weight of a full load of the box magazine then need not be accepted. It is also possible to carry out intermediate reloading at any time by pushing one or more nail strips into the box magazine in accordance with the number of nailing operations that are still to be carried out. Annoying interruptions of a nailing process due to reloading can result in them Way to be avoided.
  • Reloading a box magazine according to the invention is very simple, since the corresponding nail strips need only be inserted from behind into an opening in the box magazine. A laborious opening of the magazine or threading the strip into the driver device is not necessary. The inserted nail strips or rows are inevitably pressed one after the other into the correct position aligned with the inlet channel of the expulsion channel when they are inserted into the box magazine.
  • the box magazine according to the invention does not need to be longer than the narrow insertion magazines for a nail strip, which are customary up to now, they are only wider depending on the nail capacity to be accommodated, but can overall be kept so slim that the device can also be used in inaccessible places.
  • the nail strips or rows are e.g. pressed by means of at least one spring in the direction of a fixed stop surface which is aligned with the inlet duct of the expulsion duct.
  • the correct alignment of the respective nail strips or rows is thus carried out in a simple manner. Each time the first nail strip has been used, the next one inevitably moves into the correct feed position until the last nail strip is used up.
  • the magazine can, for example, be fixedly attached to the device body and the stop surface can be formed by a side wall of the magazine.
  • the floor is expediently adjustable in height, so that nails of different lengths can be processed with the same box magazine.
  • the transport of the nail strips or rows takes place in that at least one feed pawl projects in the direction of the interior of the magazine over the stop surface, which pawl engages between the individual nail shafts of the nails or the last nail in each case or one directly on the stop surface pressed behind nail strip or row.
  • the feed pawl can thus advance the nails of a nail strip in the alignment position to the inlet channel of the expulsion channel in the direction of the expulsion channel.
  • the at least one feed pawl expediently yields elastically when there is a force acting on it from the loading side of the magazine, but it remains locked in a protruding manner when a force acts in the opposite direction.
  • This has the advantage that the nail strips can be inserted without hindrance from behind into the box magazine along the stop surface, without having to pull back the feed pawls, but when the feed pawl moves forward, the corresponding engaging nail is carried forward.
  • the feed pawls can be moved by moving along the box magazine from a front end position to a rear end position, where they can reach behind a nail shaft again without having to be withdrawn beforehand.
  • the at least one feed pawl on an in Longitudinal direction of the magazine outside the stop surface for example pneumatically and / or spring-actuated feed cylinder is attached.
  • the feed cylinder is expediently secured against rotation about its axis, so that the respective feed pawls do not accidentally disengage from the nail shafts.
  • the feed cylinder is expediently slidably mounted on a guide rod running parallel to the magazine.
  • the displacement of the delivery cylinder against the action of the spring advantageously takes place from the air pressure intended for driving out the nail from a front to a rear end position.
  • the spring force can thus move the feed cylinder including feed pawl in the direction of the front end of the box magazine and thus press the foremost nail of the nail strip in the stop position into the expulsion position in the expulsion channel.
  • the feed cylinder in a cylinder space connected to the outside air has a helical spring received on the guide rod, which rests with its front end on an inner shoulder of the feed cylinder and at its rear end on a circumferential shoulder of the guide rod.
  • a simple pneumatic actuation of the feed cylinder is obtained when the guide rod has a bore which can be acted upon by the actuating air pressure of the working piston and which opens into a second sealed cylinder space of the feed cylinder.
  • the working stroke of the delivery cylinder should be at least twice the distance between two nails in the nail strip or row. On the one hand, this has the advantage that, in the absence of a nail in the strip or row, a next nail still comes into the driving position. On the other hand, after the end of a previous nail strip, the next one follows immediately, so that here too there is no interruption of the nailing process when the nail release button is pressed.
  • two or more feed pawls are expediently provided in the longitudinal direction of the box magazine and the working stroke of the feed cylinder is expediently at least one nail thickness greater than the distance from the feed pawl to the feed pawl in the longitudinal direction of the magazine.
  • an unlockable pawl is preferably provided for engaging behind the nail shaft of a nail of the nail strip or row respectively resting against the stop surface. This pawl avoids moving the respective nail strip or row backwards, but because of the unlockability also allows the possibility that such a strip or row is removed again from the box magazine.
  • One type of known nail strip has a number of nails which are staggered at an angle to one another and embedded in a comparatively thick plastic band. These plastic strips are so wide that the nail strip in contact with the stop surface can be moved opposite and on the following one sliding forward without the nail heads hindering each other, which could be the case with nail strips in which the staggered nails are only with the sides glued paper strips are held together.
  • the nail heads or nail tips of the nails are guided in two or more guides running in the longitudinal direction of the magazine grooves are laterally displaceably accommodated, each of which can be aligned with the inlet duct of the expulsion duct.
  • the guide grooves are so far apart from one another that adjacent nail strips or rows cannot interfere with one another in the event of relative displacement. Such guide grooves are not only able to receive the known nail strips from nails already connected to one another, individual nails can also be stored in the grooves.
  • the magazine with the guide grooves as a whole or a part having the guide grooves relative to the fixed magazine perpendicular to the plane of the guide strips or rows in the direction of the stop surface, e.g. by spring bias.
  • the entire magazine or the entire part having the guide grooves moves inevitably towards the stop surface by a distance which corresponds to the lateral spacing of the guide grooves, so that the next nail strip in each case or the next row of nails comes into contact with the stop surface.
  • the laterally displaceable magazine can, for example, overlap a guide rail running in the longitudinal direction of the magazine with a lateral projection or be guided in its lateral displacement in some other way.
  • the feed cylinder can be mounted in a longitudinally displaceable manner in the guide rail.
  • the fixed guide rail can also form the stop surface for the nails.
  • the delivery cylinder can also be supported with its rear end against a compression spring in the direction of the rear end of the guide rod.
  • the guide rod is advantageously mounted displaceably in its longitudinal direction on the device body and can be moved with the feed cylinder from a front working position into a rear release position.
  • the guide rod can be supported at its rear end by a compression spring, so that it is forced into the front working position again after the movement has taken place.
  • a pull hook is attached directly or indirectly to the feed cylinder, which grips the nail located in the drive channel.
  • the pulling hook in the retracted position expediently locks a trigger securing nose provided on the mouthpiece, sc that in this case, ie when the nail strip is pulled out, the device cannot be triggered.
  • a structurally simple configuration of the device according to the invention is obtained when the laterally displaceable magazine is guided on a guide column running transversely to the nail strip planes and is pressed in the direction of the stop surface by a compression spring arranged on the guide column. In this way, the next nail strip inevitably gets the correct position in relation to the expulsion channel when the previous nail strip is used up.
  • the laterally displaceable magazine can be locked against the action of the compression spring in its initial position, in which the nail strips or rows can be inserted into the magazine, so that easy reloading is possible, and the magazine cannot be locked against the action of the compression spring in this loading position must be held by hand.
  • the magazine itself or the part having the guide grooves can be held interchangeably on the device body. This opens up the possibility of attaching an already filled magazine or an already filled groove plate to the device in succession.
  • the part having the guide grooves can be designed as a plate-shaped packaging profile which can be inserted into the magazine. In this way, a particularly simple reloading is possible.
  • the plate-shaped packaging profile can be designed, for example, as a one-piece plastic profile. This allows simple manufacture and at the same time the advantage that the nails can slide easily in the guide grooves in the direction of the expulsion channel.
  • the guide grooves are preferably T-shaped in cross-section, the nail head being accommodated in the crossbar of the T and the part of the nail shaft directly adjoining the nail head in the subsequent leg of the T, so that the respective nail is largely secured against lateral pivoting.
  • an unlockable latching pawl engaging behind the rear end of the packaging element can also be provided, with which an unwanted slipping out of the packaging profile from the box magazine can be prevented.
  • the invention also relates to a nail magazine unit with a holding element, which carries a number of nails arranged in at least one row, for being received in a magazine of a nail driving device, in particular a nail driving device of the type described above.
  • a nail magazine unit is known in the form of a so-called nail strip (cf. DE-OS 27 50 562), in which a number of staggered nails are either embedded in at least one plastic material strip or held together by paper strips or wires glued on from the side.
  • nail strips are partially wound up as a coil storage unit.
  • Nail inserting devices that work with comparatively shorter straight, i.e. not wound-up nail strips require reloading with the individual nail strips, which can be labor-intensive, especially if the nail inserting device is equipped with a box magazine for holding several nail strips side by side.
  • the object of the present invention is therefore to create a nail magazine unit which can have a nail capacity of known nail coils, but can be used in nail driving tools with a box magazine.
  • the holding element is plate-shaped with two or more open grooves on one side of the plate for receiving two or more rows of nails side by side.
  • Such a nail magazine unit can be inserted as a whole into a box magazine of a nail driving device. After all the nails have been used up, the empty holding element is removed from the magazine and replaced with a previously or meanwhile filled nail magazine unit according to the invention. In this way, a complete reloading of the box magazine of a nail driving device of considerable capacity is possible in a few simple steps.
  • the nails are preferably longitudinally displaceably received in the grooves, so that they can be carried in the magazine of the nail driving device in a simple manner by guide pawls along the grooves in the direction of the drive-out channel of the mouthpiece of the nail driving device.
  • the nails are expediently received with their heads in the grooves, since this ensures that the nails are held securely in the holding element.
  • the grooves are T-shaped in cross section.
  • the nails can easily be inserted laterally with their nail heads and can only be torn out of such a groove in the axial direction of the nail with relatively great effort. While the crossbar of the T-slot takes up the nail head itself, the part of the nail shaft directly adjacent to the nail head is securely guided in the leg of the T-slot, which is open to the outside, against excessive lateral angular deflection of the nail.
  • the grooves preferably run parallel to one another, so that the individual rows of nails can be pushed out of the holding element in the same direction.
  • the holding element For holding the nail magazine unit in a box magazine of a nail driving device, the holding element preferably has a substantially rectangular, possibly slightly conical shape in plan view.
  • the holding element is preferably designed as a one-piece plastic profile. This not only facilitates the manufacture, but also a favorable guidance of the nails in the grooves.
  • the ends of the grooves can be separated, for example torn open or cut, closed. As long as they are closed, the holding element serves as packaging for the entire nail field consisting of individual rows.
  • the front of the grooves is opened by tearing or cutting open, while the back can remain closed so that no nails can fall out.
  • the holding element has at least one cutout for the engagement of a locking pawl of the nail driving device.
  • a locking pawl can thus easily prevent the nail magazine unit from accidentally falling out of the box magazine of the nail driving device.
  • the holding element prefabricated nail strips of a known type can also be inserted into the individual grooves. This is particularly advantageous if the plate-shaped holding element inserted into the nail driving device is to be fully or partially reloaded.
  • the holding element has elongated material weakening lines which run parallel to the grooves and which allow easy separation of a larger nail magazine unit into smaller subunits. In this way, it can be adapted to the special requirements of a nailing process or to the width of a given box magazine. Likewise, lines of weakness across the grooves are possible in the holding element, so that subunits with more or less long rows of nails can be produced from a given nail magazine unit.

After this Unlocking the magazine box 2 from this loading position, the work can be continued.
  • a constant reloading of the magazine 2 is also possible here in a simple manner.
  • a profile part 26 which is already completely filled with nails 4 according to FIG. 13 can be exchanged for an empty profile part 26 of the magazine 2.
  • the independent profile part 26 according to FIG. 13 does not have nail strips, but rather nail rows 3, the nails 4 of which need not be connected to one another in the longitudinal direction.
  • the profile part 26 with the pre-stored nails 4 thus represents a new type of nail packaging unit which allows a magazine 2 to be loaded quickly and completely both with nail strips 3 and with a field of individual nails 4.
  • a special filling device can be provided for filling the profile part 26 with unmagazineized nails 4, which can run while the nail driving device 1 according to the invention is used.
  • the profile part 26 has a nail holding capacity which corresponds approximately to the capacity of the nail strip pack P from FIG. 5 and completely fills the interior of the box magazine 2.
  • the nail magazine unit 81 according to FIG. 14 for nails 82 has an essentially rectangular, plate-shaped holding element 83 made of plastic. It has on its underside several, in the illustrated case four, grooves 84 which run parallel to one another and have a T-shaped cross section. The nails 82 are received in rows with their heads 85 in the grooves 84.
  • Such a unit consisting of holding element 83 and nails 82 arranged in the manner of a matrix is simple, suitable for quick and complete filling of a box-shaped magazine of a nail driving device.
  • the ends of the grooves 84 can be closed on both sides during the manufacture of the packaging unit, so that the nails 82 cannot fall out.
  • the front side of the grooves 84 can then be torn open or cut open. This is possible in particular if the closure has been carried out with the aid of an adhesive strip or with the aid of a thin plastic wall formed in one piece with the holding element 83.
  • the plate-shaped holding element 83 has a plurality of cutouts 86 for the engagement of a locking pawl of the nail driving device in order to prevent it from falling out of the box magazine unintentionally.
  • the holding element 83 can furthermore have longitudinal and / or transverse material weakening lines 87, 87 ', along which the nail magazine unit 81 can be divided into smaller sub-units if required.
  • the holding element 83 is evidently not only suitable for receiving individual non-magazine nails 82, but also for receiving pre-magazine nail strips in the form of strips, which is indicated on the rightmost row of nails in the drawing by a connecting strip 88 shown in broken lines .
  • Such a nail magazine unit 81 can be used in such a way that it is reloaded after all the nails it has consumed have been used, either with prefabricated nail strips or with individual non-magazine nails.
