[0015]
In the drawing, reference numeral 801 denotes a compressed air source such as a compressor; h and o are open to the atmosphere; outlet ports e and f of the operation valve communicate with the ports (1) and (2), respectively; 3 ▼ communicates with the pilot air circuit Y, respectively.
Further, the outlet port m of the trigger valve communicates with the pilot air circuit x of the operation valve and the port (4) at the upper end of the chuck cylinder 400, and the port n communicates with the inlet port g of the operation valve 900. .
[0016]
Further, the rod cover 460 is provided with a port (5), through which the air chamber 480 communicates with the port k of the tape air cylinder 710, and when the nosepiece 600 rises to the top dead center (FIG. 18) The compressed air in the air chamber 480 is supplied to the tape air cylinder 710 through the groove 612 at the bottom of the cylinder 610 (FIG. 19).
[0017]
the aboveWorks as follows. Normally, the blind rivet holder 740 is stored in the storage case 750 of the continuous riveter in a wound state, and when it is not crimped, the state is as shown in FIGS. 12 and 13, and the push button 810 (trigger) is released. The blind rivet 740 is resiliently held by the elastic ring 621 on the nosepiece 620 so as not to fall down.
[0018]
When the rivet body 742 of the blind rivet 740 is inserted into the hole of the sheet metal 760 as shown in FIG. 14 and the push button 810 is pressed, the trigger valve 800 moves as shown in FIG. 15, so that the compressed air passes through the ports s → n, The air flows into the rear chamber 202 of the air cylinder 200 from the port (1) through the port g → e of the operation valve 900, and the piston 220 advances, so that the oil piston 211 also advances, and the oil in the oil chamber 212 , The jaw case piston 500 is pushed up by a predetermined distance.
[0019]
Therefore, the jaw case 510 is raised.
In this case, since the pair of jaws 540 are urged downward by the spring 520 via the jaw pusher 530, the jaws 540 protrude downward while sliding on the tapered surface 511 of the jaw case 510, and approach each other. The blind rivet 740 rises while grasping the center axis 741 thereof. The blind rivet 740 is caulked by the rise of the shaft 741, and then the shaft 741 is cut because the rivet body 742 is stopped at the tip of the nosepiece 620.
[0020]
In this case, since the air chamber 480 and the front chamber 201 of the air cylinder 200 are open to the atmosphere from the port (2) through the ports f → h of the operation valve 900, the nose piston 600 is pressed downward and the jaw case piston Only 500 rise.
When the piston 220 advances as described above, the air in the rear chamber 202 is supplied to the pilot air circuit Y through the port (3), the operating valve 900 advances, and the state shown in FIG. 19 is reached, and the air from the air pressure source 801 is supplied to the port s → The air in the rear chamber 202 of the air cylinder 200 is supplied to the port (2) through the ports n → g → f, and the air in the pilot air circuit x and the air in the air chamber 440 are supplied to the atmosphere through the ports m → o. Released to
[0021]
Accordingly, as shown in FIGS. 16 to 18, the jaw case piston 500 and the nose piston 600 rise to the top dead center.
FIG. 16 shows that the oil piston 211 returns (the piston 220 naturally also returns), the nose piston 600 rises, returns to a position close to the bowl-shaped piston 550, and pressurized air is blown into the vacuum ejector 420. Vacuum in case 410 is started. Further, the nose piston 600 rises with respect to the jaw case piston 500, and the lower wall 611 of the cylindrical body 610 contacts the lower end of the jaw case 510, and the upper end of the nose piece 620 pushes up the tip of the jaw 540, so that the jaw 540 is released. It will be in the state that was done.
[0022]
FIG. 17 shows a state where the jaw case piston 500 and the nose piston 600 are rising, and shows a state where the mandrel 741 is sucked into the mandrel housing case 410 through the mandrel raising pipe 430.
[0023]
FIG. 18 shows a state in which both the jaw case piston 500 and the nose piston 600 are at the top dead center. At this time, since the compressed air is supplied from the port (5) to the port K of the tape air cylinder 710, the tape piston 712 is advanced, the feed claw 713a is advanced along the long hole 722, and the feed claw 713a engaged with the feed hole 732 of the blind rivet holder 730 pulls out the blind rivet holder 730 from the storage case 750 and guides it. The tip is moved by one pitch along the ridge of the plate 720, and the tip of the spindle 741 is set on the axis below the nosepiece 620.
[0024]
Next, when the push button 810 is released, the valve portion G is brought into the state shown in FIG. 13, and the trigger valve 800 returns to the original position by the force of the spring 820, so that the compressed air of the compressed air source 801 passes through the port m and the operation valve 900 Since the air is supplied to the pilot air circuit X, the operation valve 900 also moves backward. At this time, the compressed air in the pilot air circuit Y passes through the port (3) → (2) and is released to the atmosphere from the port f → h.
[0025]
At the above valve position, the compressed air is supplied to the air chamber 440 from the port (4) through the port s → m of the trigger valve 800, and the compressed air in the air chamber 480 is released to the atmosphere through the port (2) → f → h. Since both the jaw case piston 500 and the nosepiece 600 descend to the bottom dead center, the jaw 540 opened through the nosepiece 620 holds the center shaft 741 of the blind rivet 740 and the nosepiece 620 The leading end bends the upper and lower tabs 731 of the blind rivet holder 730 downward and descends. The lowering of the nosepiece 620 will be described in detail with reference to FIGS.
[0026]
When the nosepiece 620 is lowered, the supply of the compressed air to the tape air cylinder 710 is stopped, and the compressed air of the tape air cylinder 710 is released, so that the tape piston 712 is retracted to the original position by the action of the spring 711, but the blind rivet holder Since the movement of 730 in the reverse direction is stopped by the non-return claw 723, the feed claw 713a is disengaged from the feed hole 732 and moves forward one pitch while the blind rivet holding member 730 is stopped, and the feed hole 732 is located at the front. Engage with.
At this time, since the blind rivet holder 730 is resiliently pressed against the guide plate 720 by the plate spring 770 for preventing displacement, the blind rivet holder 730 is securely engaged with the feed claw 732 without displacement.
[0027]
Thus, preparation for caulking the blind rivet 740 is completed.
The subsequent operation is the same as the operation described above, and the blind rivet 740 can be continuously caulked by repeating the above operation.
[0028]
21 to 24 show a state in which the nosepiece 620 is lowered, and FIG. 21 shows a state in which one blind rivet 740 has been fed. The head 742a of the rivet body 742 is located inside the lower tab 731.
FIG. 22 shows a state in which the mandrel 741 is inserted into the nosepiece 620 and the tip of the nosepiece 620 bends the upper tab 731.
[0029]
FIG. 23 shows that the nosepiece 620 is further lowered, the upper tab 731 is completely bent, the mandrel 741 is inserted through the nosepiece 620 and is loosely fitted in the jaw 540, and the rivet body is in contact with the tip of the nosepiece 620. 742 a shows a state in which the lower tab 731 is slightly bent, and the base end of the lower tab 731 is supported by the projection 725 of the lower guide, so that the projection 725 and the head 742 a are connected to the lower tab 731. The blind rivet 740 overcomes the resistance of the elastic ring 621 and is completely inserted into the nosepiece 620 up to the head 742a by the resistance force required to bend.
[0030]
FIG. 24 shows a state in which the blind rivet 740 has been completely inserted into the nosepiece 620 and has been lowered to the bottom dead center, and the lower tab 731 has also been completely bent.
[0031]
[Problems to be solved by the invention]
As described above, in the conventional continuous riveter, rivets are automatically supplied and can be continuously struck.
However, since the rivet 740 is supplied after being inserted into the rivet holder 730, the position of the rivet 740 may deviate from the supply reference position. FIG. 10 and FIG. 11 are a front view and a bottom view of the rivet holder showing this state, and 740a shows a rivet whose position has been shifted. The misalignment of the rivet 740a is caused by a cause such as the tab 731 being improperly formed or deformed, or a rivet not being correctly inserted into the tab.
If the rivet 740 is displaced in this way, the center axis of the rivet 740 is not aligned with the center axis of the rivet 740 even if the nose piece 620 is lowered. It is not inserted into the 620, resulting in an empty shot.
[0032]
In view of the above, an object of the present invention is to provide a rivet positioning device that prevents a rivet from being displaced in a continuous riveter.
[0033]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a blind rivet provided at an advancing / retreating path of a nosepiece at a supply position of a blind rivet, and presses and supplies a blind rivet inserted and supplied to a rivet holder toward the rivet holder. Device for performing
A positioning member pivotally attached to the mounting base material, and a spring for urging the positioning member in a direction to press the center axis of the blind rivet, the positioning member is located at a blind rivet positioning position at the tip. A V-groove is provided, and from the side where the blind rivet is supplied to the V-grooveIt is an inclined surface for guiding the blind rivet inserted and supplied to the rivet holder into the V-groove, and a plurality of positioning members are provided in a vertical step with the V-groove on the same axis.It is characterized by the following.
[0034]
Therefore, the V-groove of the positioning member is formed at a rivet supply position (a position coinciding with the axis of the nosepiece), and the supplied rivet is guided to the V-groove along the inclined surface of the positioning member. The rivet supplied since it is pressed is always positioned at the supply position. In addition, since the positioning member is rotatable, even if the nosepiece descends (advance), the positioning member can be pivoted and pushed down (advance).In addition, since a plurality of positioning members are provided in a vertical manner, the rivets are reliably positioned.
[0035]
It is preferable that the positioning member has a substantially L-shape, because positioning by pressing a rivet is easy.
In addition, even if the positioning member can move forward and backward with respect to the mounting base material, it can press and position the blind rivet by being urged in the advance direction by a spring.
[0036]
Further, the positioning memberIsIt may be provided facing. By doing so, the positioning of the rivet is further ensured.
[0037]
【Example】
Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 9, the same reference numerals as those in the conventional example indicate the same components.
FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is a perspective view showing a use state of the present invention. A rivet positioning device 1 includes a mounting base 2 and a rotatable mounting base 2. The positioning member 3 is pivotally mounted on the rivet 740 by the spring 4 (see FIGS. 3 and 4) wound around the pivot 5 (the direction of the arrow in FIG. 2). Has been energized.
[0038]
The positioning member 3 is formed of an L-shaped plate body, the base end side of which is pivotally connected with a pivot 5, and the front end surface of which is provided with a V-groove 6 and a rivet 740 at a substantially central portion from the side where the V-groove 6 is supplied. An inclined surface 7 is formed. The V-groove 6 is for positioning the rivet 740 here, and the inclined surface 7 is for the rivet 740 to be easily guided to the V-groove 6.
[0039]
The rivet positioning device 1 is mounted such that the V-groove 6 of the positioning member 3 is positioned on the axis of the nosepiece 620 (rivet supply position) on the nosepiece advance / retreat path at the rivet supply position of the continuous rivet. Therefore, the position at which the supplied rivet 740 is guided by the inclined surface 7 of the positioning member 3 and is fitted and pressed into the V groove 6 is the position at which the rivet 740 is supplied to the nosepiece 620, and the center axis of the rivet 740. 741 and the axis of the nosepiece 620 coincide with each other.
[0040]
FIG. 3 is a partial side view of the continuous rivet showing the state where the rivet positioning device 1 is attached, and FIG. 4 is a partial front view of the continuous rivet just before rivets are supplied.
The rivet 740 is inserted and supplied to the rivet holder 730 as shown in FIG.

FIG. 5 is a side view (A) and a front view (B) showing a state where the rivet is supplied to a supply position to the nosepiece.
When the rivet 740 moves from the state shown in FIG. 4 to the state shown in FIG. 5, the rivet 740 advances along the inclined surface 7 of the positioning member 3 and finally fits into the V-groove 6. Since the positioning member 3 is urged by the spring 4, the positioning member 3 is pressed by the positioning member 3 in a state of being fitted into the V groove 6.
The position of the rivet 740 fitted and pressed in the V-groove 6 is the supply position of the rivet 740 to the nosepiece 620 because the V-groove 6 is located on the axis of the rivet 740 and the nosepiece 620. That is, the supplied rivet is always positioned at the rivet supply position.
[0042]
FIG. 6 is a side view (A) and a front view (B) showing a state in which the nosepiece has been lowered halfway.

Is always inserted into the nosepiece 620 that has descended.
[0043]
FIG. 7 is a side view (A) and a front view (B) showing a state in which the nosepiece is lowered to the lower limit. When the nosepiece 620 is further lowered, the nosepiece 620 is lowered by rotating the positioning member 3 against the urging force of the spring 4 as shown in FIG. It is completely attached to the nosepiece 620. Subsequent steps are the same as in the above-described conventional example.
When the nosepiece 620 has been lifted, the positioning member 3 is restored by the spring 4.
[0044]
Although the positioning member 3 of the above embodiment is pivotally attached to the mounting base 2 so as to be rotatable, the positioning member 3 can be moved forward and backward with respect to the mounting base 2 and attached in the advance direction by a spring. It may be an energizing mode.
In this case, means for retreating the positioning member 3 when the nosepiece 620 is lowered is required. For example, the portion of the positioning member 3 with which the nosepiece 620 abuts is a slope, and when the nosepiece 620 abuts, it is pressed against the spring.
[0045]
FIG. 8 is a perspective view showing another embodiment of the present invention, and FIG. 9 is a perspective view showing its use state.
The present embodiment is a case where a plurality of (two stages in the figure) positioning members 3a and 3b are provided vertically in two stages, and the rest is the same as the above-described embodiment. In this case, the upper and lower positioning members 3a and 3b are provided with V-grooves located on the same axis.
According to this example, since the rivet 740 can be positioned by the upper and lower positioning portions 3a and 3b, there is an advantage that the rivet 740 can be positioned more accurately.
[0046]
In the above embodiment, the positioning portions 3, 3a, 3b are provided only on one side. However, they may be provided opposite to each other, and may be positioned by being sandwiched from both sides. Also in this case, the positioning becomes more reliable.
[0047]
