Description

  The present invention relates to a screw ring nail and a screw ring nail connector used by being loaded into a nailing machine capable of continuously driving the screw ring nail.

  Conventionally, as a coupling body that holds a large number of nails, rivets, and the like in parallel, one that supports the nails, rivets, etc., with two parallel wires is known (see, for example, Patent Documents 1 and 2). In the case where the nail and the rivet are supported by two parallel wires, the nail and the rivet are supported by being welded to the wire or wound by the wire. These nails, rivets, and other connected bodies are loaded into the magazines of the respective automatic driving machines, driven by an operating mechanism, and supplied and driven in one by one.

Conventionally, screw ring nails subjected to screw processing and ring processing have been provided (see, for example, Patent Documents 3 and 4). FIG. 4 shows a connecting body 11 in which such a screw ring nail 12 is supported by welding with two parallel wires 13 and 13.
Japanese Examined Patent Publication No. 39-258 Japanese Patent No. 3511911 Japanese Utility Model Publication No. 54-52562 Japanese Utility Model Publication No. 56-28329

  However, in the coupling body 11 shown in FIG. 4, the screw ring nail 12 is welded 14 and supported by the wire 13. However, since the screw ring nail 12 is subjected to screw processing and ring processing, the wire 13 is Since the ring processing groove is in contact with the peak portion of the screw processing and the ring processing groove is present in this peak portion, the contact area is small. For this reason, when driving with the nail driver, the wire 13 as the connecting material is divided, and the wire piece that is fixed to the screw ring nail 12 and driven together is detached and scattered around when it is driven into the object. There is a problem that the worker is scattered and the worker is damaged.

On the other hand, if the support part (welded part) of the screw ring nail is made smooth, the pulling strength is reduced at that part, so that the pulling strength of the screw ring nail as a whole is reduced accordingly. is there.
The present invention is intended to provide a screw ring nail and a connecting body thereof that solve such problems.

  In order to solve the above-mentioned problems, a screw ring nail according to the present invention is composed of a head, a shaft portion, and a sharp tip portion, and a plurality of locking teeth that are reverse in the pulling direction are ring-processed on the shaft portion. A ring processing portion arranged in a row and a screw ring portion that is processed with a screw and a plurality of locking teeth that are reverse in the pulling direction are formed on the crest of the screw. To do.

  With this configuration, when the screw ring nail is driven into the object, the screw ring nail enters while being rotated by the screw. Although it is easy, screw processing and ring processing (locking teeth) are applied in the pulling direction, so that the fastening force by the screw and the resistance force against pulling of the locking teeth that are opposite in the pulling direction are demonstrated. The nail pulling resistance is high. Accordingly, even if a force in the pulling direction acts on the nail or a vibration is applied to the nailed object, for example, a pallet, the object in which the screw ring nail is nailed by a large resistance force in the pulling direction (for example, It does not surface from the pallet.

Further, the screw ring nail according to the present invention is such that the head of the screw ring nail is formed in an arc surface that is smoothly continuous from a peripheral surface to a flat upper surface except for a jaw portion that is continuous with a shaft portion. Features.
In addition to the above action, the screw ring nail driven into the nail target in this configuration should be able to lift the nail head even if it rises from the surface of the nail target due to vibration of the nail target or other causes. Since the portion is a smooth arc surface from the peripheral surface to the flat upper surface, it is possible to prevent damage to the bottom surface of the transported object or the like placed on the nail target (for example, pallet).

  In addition, the screw ring nail connector according to the present invention includes a head, a shaft portion, and a sharp tip portion. The shaft portion is provided with a plurality of rows of locking teeth that are reverse in the pulling direction. A screw ring nail in which a ring processing portion formed and a screw ring portion in which a plurality of locking teeth that have been screw-processed and are reverse-processed in the pulling direction are formed on the crest of the screw are formed in the ring processing. The parts are connected to a metal wire or sheet tape and held in parallel.

With this structure, the screw ring nail is connected to the metal wire or the sheet tape in the ring processing portion of the shaft portion, and is welded to the metal wire and held in parallel. Compared to welding with a metal wire, the adhesion force due to welding with the metal wire is stronger, and the metal wire piece separated from the metal wire at the time of driving is driven into the object together with the screw ring nail while remaining attached to the screw ring nail. It is. Therefore, the metal wire piece does not detach from the screw ring nail, and is not scattered around and does not hurt the operator.
In addition, the metal wire piece driven into the object together with the screw ring nail acts as a retaining member for the screw ring nail, and the pulling strength is further improved. Further, since the engaging teeth that are reverse in the drawing direction are ring-processed in the portion welded to the metal wire (wire) of the screw ring nail, the pulling-out strength is not lowered.
In addition, since the screw ring nail of this connection body is the same structure as the above-mentioned screw ring nail, it cannot be overemphasized that there exists the same effect | action and effect.

Further, the head of the screw ring nail in the screw ring nail coupling body is formed in an arc surface that is smoothly continuous from a peripheral surface to a flat upper surface except for a jaw portion continuous to the shaft portion. To do.
With this configuration, in addition to the function of the screw ring nail connector, the screw ring nail driven into the nail target object should float from the surface of the nail target object due to vibration of the nail target object or other causes. Even in this case, the head of the nail is a smooth circular arc surface from the peripheral surface to the flat top surface, preventing damage to the bottom surface of the transported object placed on the nail target (for example, pallet). it can.

According to the screw ring nail and the connecting body thereof of the present invention, the following effects are obtained.
(1) When the screw ring nail is driven into the object, the screw ring nail enters while being rotated by the screw. Since it is easy and the screw processing and the ring processing of the locking teeth are performed in the pulling direction, the synergistic effect of the fastening force by the screw and the resistance force against the pulling of the locking teeth that reverses the pulling direction, The nail pulling strength is very high.

(2) The pull-out strength (pull-out strength) is greater than that of conventional screw ring nails. When used for pallets, etc., even if a load is placed on the pallet and lifted with a forklift, etc., the plate forming the pallet will be peeled off. Accidents are reduced and a strong pallet is created. Further, the screw ring nail driven from the plate forming the pallet comes out and the nail protruding from the plate does not damage the load placed on the pallet.
(3) Since the pull-out strength is high, if the same pull-out strength is required, it can be handled with a nail that is one rank shorter, and resources such as steel can be reduced.

(4) Even if the screw ring nail driven into the nail target object floats from the surface of the nail target object due to the vibration of the nail target object or other causes, the head of the nail is Since the arc surface is smooth from the flat top surface to the flat top surface, it is possible to prevent the bottom surface of the transported object or the like placed on the nail target (for example, pallet) from being damaged.

(5) Since the screw ring nail is welded to the metal wire in the ring processing portion of the shaft portion and held in parallel, the screw ring nail connection has a stronger adhesive force than welding to the screw ring processing portion. The metal wire segment cut from the metal wire at the time of driving is driven into the object together with the screw ring nail while being fixed to the screw ring nail. Therefore, the metal wire pieces cut off from the metal wire at the time of driving are not scattered around the screw ring nail without being separated from the surroundings, and the operator is not damaged.

(6) In addition, the metal wire piece driven into the object together with the screw ring nail acts as a stopper for the screw ring nail that has been driven in, and the pull-out strength is improved.
(7) Further, since the engaging teeth that are opposite to each other in the drawing direction are ring-processed in the portion welded to the metal wire of the screw ring nail, the drawing strength is not lowered.
(8) Moreover, according to this connection body of a screw ring nail, it can be used with a conventional nail driver.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a front view of a screw ring nail showing an embodiment of the present invention, and FIG. 2 is an explanatory sectional view (a) and (b) showing a driving state of the screw ring nail.

  As shown in FIG. 1, the screw ring nail 10 includes a head portion 1, a shaft portion 3, and a sharp tip portion 2. A conventionally known shape can be adopted as the shape of the head 1, and there is no particular limitation. In this example, as shown in FIG. 1, a flat upper surface 1 a is formed from the peripheral surface 1 d except for the jaw portion 1 c continuous to the shaft portion 3. It is formed in the circular arc surface smoothly continued over. If the head 1 has such a shape, the screw ring nail 10 driven into the nail target 9 as shown in FIG. As shown in FIG. 2 (b), even when the nail head 9 floats from the surface of the nail object 9, the nail head 1 is a smooth arc surface from the peripheral surface 1d to the flat upper surface 1a. (For example, a pallet) 9 is preferable because it does not damage the bottom surface of a transported article or the like placed on the pallet.

  Moreover, a conventionally well-known shape can be adopted as the shape of the sharp tip 2 and is not particularly limited. For example, diamond dropper, chisel point (chisel point), pointless, etc. can be mentioned.

In addition, the shaft portion 3 has a ring processing portion 7 in which a plurality of rows of locking teeth 6 which are reversely formed in the drawing direction (arrow A direction) are ring processed, and a screw processing. A screw ring portion 4 in which a plurality of locking teeth 6 that are opposite to each other in the drawing direction (the direction of arrow A) is ring-processed is formed in the portion.
The locking teeth 6 to be ring-processed are formed of stepped portions 6a extending from the upper end of the tapered peripheral surface 6b that gradually expands toward the upper end to a right angle or an acute angle with respect to the axis of the shaft portion 3, and a plurality of these are provided in a row. 7 Therefore, the locking teeth 6 are so-called reverse stitches in which the stepped portion 6a acts as a pulling resistance for locking the object to be driven (for example, fiber of wood) in the pulling direction of the screw ring nail 10, and in the driving direction. Is a so-called order that allows the taper peripheral surface 6b to enter without being obstructed by an object to be driven (for example, wood fibers).

The screw ring portion 4 is formed by screw processing, and a plurality of locking teeth 6 that are reverse in the drawing direction are formed in a crest portion of the screw 5 by ring processing. The screw ring portion 4 of the present example is formed by previously forming a plurality of locking teeth 6 similar to those described above and then screwing the same to form the screw 5 in the method of forming a screw 5 thereon. The screw ring portion 4 is formed by ring-processing a plurality of locking teeth 6 that are opposite in the direction, but after the screw 5 is formed first, the locking teeth 6 are ring-processed on the mountain portion of the screw 5. May be.
The lead angle of the screw 5, the interval between the peaks and the peaks, the interval (width) between the bottoms of the valleys of the screw 5, the height of the peaks of the screw 5, and the like are appropriately selected according to the object to be used. For example, if the lead angle of the screw 5 is made large (acute angle), driving becomes easier, and if the lead angle is made small (obtuse angle), the pulling strength can be increased.

Thus, according to the screw ring nail 10, when driving into the nail target 9, the screw 5 enters while being rotated by the screw 5. However, since the screw 5 processing and the ring processing (locking teeth 6) are applied in the extraction direction, the tightening force by the screw 5 and the reverse direction in the extraction direction. The resistance against pulling out of the locking teeth 6 is exerted, and the pulling-out resistance of the nail becomes high.
Therefore, even if a force in the pulling direction acts on the screw ring nail 10 that has been struck or vibration is applied to the nailed object 9, for example, a pallet, the screw ring nail 10 becomes nail due to a large resistance force in the pulling direction. It does not surface from the hit object 9 (for example, pallet).

Next, a screw ring nail connector according to an embodiment of the present invention will be described with reference to FIG. FIG. 3 is a perspective view of a screw ring nail connector showing an embodiment of the present invention.
The connecting body of the screw ring nail 10 is configured by a plurality of screw ring nails 10 being connected to a metal wire or a sheet tape and held in parallel. FIG. 3 shows a case where the screw ring nail 10 is connected to the metal wire 8 by welding.

  The screw ring nail 10 is the same as that described above, and is composed of the head 1, the shaft 3 and the sharp tip 2 and the shaft 3 is provided with a locking tooth 6 which is reverse in the pulling direction. A ring processing portion 7 that is processed and arranged in a plurality of rows, and a screw ring portion 4 that is screw-processed and has a plurality of locking teeth 6 that are reversely formed in the pulling direction at the crest portion of the screw 5. ing. Since the shape of the head 1, the configuration of the screw 5, the configuration of the locking teeth 6, and the like are the same as those of the screw ring nail 10 described above, the same reference numerals are given and detailed description is omitted. Therefore, this screw ring nail 10 also has the same operations and effects as described above.

The screw ring nail 10 is provided with at least two ring processing portions 7 at a predetermined interval in the middle of the shaft portion 3, and the screw ring nail 10 is composed of two pieces of metal that are parallel in the vertical direction in the ring processing portion 7. A plurality of wires (for example, wires) 8 and 8 are connected to each other by welding and are held in parallel.
Here, the screw ring nail 10 is welded and connected to the metal wire 8 in the ring processing portion 7 in order to strengthen the connection between the screw ring nail 10 and the metal wire 8 by welding. When the metal wire 8 is welded, the metal wire 8 comes into contact with the crest portion of the screw 5, and the contact area is small because the crest portion 6 is present in the crest portion, and therefore the adhesion of the welded portion is weak. Yes, if the adhesive force between the screw ring nail 10 and the metal wire 8 is weak, the metal wire 8 is divided and fixed to the screw ring nail 10 to be driven into the object together when driven by a nail driver. The pieces are not preferable because they are separated when they are driven into the object, and are scattered and scattered around the object.

  The connection body of the screw ring nail 10 thus configured is used by being bundled in a spiral shape and loaded in a magazine of a nailing machine. The loaded screw ring nail connected body is sequentially fed from the head of the screw ring nail 10 held in parallel by the nail feeding mechanism of the nail driver and supplied to the nose portion, and is hit by the driver of the nail driver. Then, it is driven into a pallet constituting member for material conveyance, for example. Thus, the object, such as a pallet, can be quickly assembled.

Thus, when the screw ring nail 10 is driven into the object, the screw ring nail 10 is a metal wire (for example, a wire) in the ring processing portion 7 of the shaft portion 3. ) Since it is welded to 8 and held in parallel, the adhesive force due to welding with the metal wire 8 is stronger than when welding with the screw ring portion 4, and the metal wire piece cut off from the metal wire 8 at the time of driving Is driven into the object together with the screw ring nail 10 while adhering to the screw ring nail 10. Therefore, the metal wire piece does not detach from the screw ring nail 10 and does not scatter around or damage the operator.
Further, the metal wire piece driven into the object together with the screw ring nail 10 is engaged with the wood fiber as the object to be driven and acts as a pulling resistance, and the pulling resistance is further improved.
Further, since the portion welded to the metal wire 8 of the screw ring nail 10 is the ring processing portion 7 of the locking tooth 6, the portion to be welded also has the locking teeth 6 that are opposite in the drawing direction, Yield is not reduced.

  The above embodiment does not limit the present invention, and various modifications are allowed without departing from the spirit of the present invention.

It is a front view of a screw ring nail which shows an embodiment of this invention. It is sectional explanatory drawing (a) (b) which shows the driving state of a screw ring nail. It is a perspective view of the connection object of a screw ring nail which shows an embodiment of this invention. It is a perspective view which shows a prior art example.
