Definitions

  • the present invention relates to a feed, tilt and front loading device for tear, pop, blind, hollow and the like. Rivets with rivet guns.
  • the rivet guns which are automatically supplied with rivets and are attached to the panels to be joined, have been known for a long time.
  • the automatic and constant supply of the rivets preassembled on the nail is ensured that the rivet gun is loaded through an opening from behind with a holding pliers, the rivet being fed with the nail through a compressed air supply pipe on the side.
  • the jaws advance towards the inside and sit on the nail of the rivet, which is held by the pliers.
  • the rivet that comes from the vibrating feeder with the forward nail and the rivet itself is currently tipped into an angular swing reverser located at the exit of the vibrator.
  • GB-A 2 013 548 discloses feeding, tilting and automatic front loading devices for rivets with a rivet gun, with a feeding means of the rivet with nail in reverse position, from the drum to a front loading device, with a front loading device of the nail into the opening of the head of the Rivet gun, consisting of two intermediate links which are not in alignment with the axis of the rivet gun, which are individually articulated at one end on a claw, which is connected in one piece to a slide, which slides on a shaft of the rivet gun and is mounted on a head provided with spring pliers at the other end. said guideway guiding the spring pliers to the feed means when the rotor is pushed back and to the axis of the opening when the rotor has advanced.
  • the drum with alternating rotation by 180 ° to reverse the rivet, is very reliable with the mechanical reversal, which is purely mechanical in terms of kinematics, and therefore clamping is not possible.
  • the rivet with the inverted nail is pneumatically guided to the outer magazine of the rivet gun, which positions it frontally with a play of cams and pontics with the nail perpendicular to the opening of the head, causing it to go back and place it in the open jaws where it is is held by a resilient locking device. Now the positioning device goes back, the jaws contract and the nail can be torn out, as is the case with riveting devices with manual feed.
  • the riveting device comprises a closed, chassis-mounted underframe 1, in which there is a vibration supply device, oleodynamic and electronic compressed air drives, an order head with alternating rotation, which is shown in FIG. 4, a control panel 2 of the vibrator, a control panel of sequence 3, Zulei lines 4, both the rivets and the pneumatic and oleodynamic means (not described individually since they are known in terms of type) and a ready-to-use rivet gun 5 in the hand of the user.
  • the panel 2 has two selector switches 21 and 22, each for the operation of the riveting device with free times, for manual use and with an automatic cycle.
  • the table 2 also has a regulator provided with a rotary handle 23, which actuates a device for changing the vibration range, which is to be adjusted in each case according to the dimensions and weights of the nails with rivets.
  • Fig. 3 shows the arrangement of controls and operating signals for the various phases, both in the manual and in the automatic cycle.
  • the various phases are operated by electronic and electrical techniques known and therefore not described.
  • Fig. 4 shows the organization head with alternating rotation. It comprises a rail 40 of a vibrator of known design, on which, driven by the vibration, the rivets, which are hanging properly on the ring of the rivet 42, advance with the nail 41 pointing downwards.
  • the drum 43 of the order head is attached.
  • Fig. 4 A the drum can be seen from the entry side of the nail 41; on this side the drum is provided with a vertical radial cavity 46 with a closed end.
  • the drum 43 can be seen from the opposite side of the side shown in Figure 4 A.
  • the holder members and the elements with alternating rotation of the drum which consist of the pinion 45 in one piece with the order drum 43 and the toothed rack 44, which is preferably moved by a compressed air piston 44 'which, as each nail advances after command and after the frequency required by the control panel 3 goes up and down.
  • the drum 43 with the corresponding pinion 45 are mounted on a holder 47 which is provided with an outlet pipe 48 opening into a hose 49.
  • the mouth of the drain pipe 48 is exactly at the level of the cavity 46 of the drum 43 when the drum has rotated 180 ° , as shown in Fig. 4 C.
  • the drum 43 is provided with a compressed air line 50 with a corresponding valve, at the same height and on the surface opposite that of the cavity 46 into which it merges.
  • a compressed air pulse coming from the line 50 and driven by the drive causes the nail with rivets to go down into the tubes 48 and 49 by actuating the ring thereof. always with the rice nail in the reverse position, and drives it until it comes into a pair of pliers 52 of the positioning device 6 of the rivet gun 5, to which the tube 49 is connected.
  • This positioning device essentially comprises two bodies, a fixed 63 and a movable 70, which are connected by a cam 64 and a pin or ratchet tooth 67 running therein.
  • the fixed body 63 which is attached to the side of the body of the rivet gun 5, comprises a tube 49 'which is connected to the feed line 49 and a parallelepipedon-shaped cam guide track 64; this consists of two cavities 65 and 65 ', which run parallel to the axis of the riveting device 5, and of two oblique, parallel cavities 66 and 66', which are connected to the previous ones and are oblique in relation to the above-mentioned axis.
  • the movable body 70 comprises two levers 68 and 68 ', both of which are non-aligned in relation to the rivet gun and individually articulated with different center distances, on the side near the fixed body 63, on a claw 71 made of one piece with a runner 69, and on the opposite side on a head 51 provided with spring pliers 52.
  • the lever 68 ' is longer corresponding to the side near the fixed body 63, and its extension is provided with a ratchet tooth 67 which runs in the cavities of the cam guideway 64.
  • the rotor 69 slides on the shaft 69 ', which is attached to the rivet gun 5, under the action of a compressed air piston which is located in the body of the rivet gun (not shown in the figure).
  • the head 7 has a spring wedge 61 made of hardened steel with a cut edge, with an inclination angle of approximately 35 ° to the entrance, which is inserted laterally into this head and by a snap ring 62 in its seat is held.
  • the cutting edge created in this way does not hinder the entry of the nail, which can run at the angle of inclination, only the snap ring 62 being deformed.
  • the spent nails are recovered by dropping them into a delivery line and letting them come out through a pipe 58 and passing them to a collection basket, being driven by the air flowing out of the pipe 57.
  • the simple and safe functioning of the device of the present invention can be summarized as follows: the rivets 42 with the nails 41 hang on the rails 40 and are advanced by a vibrator until one after the other into the cavity 46 of the order drum 43 with the after bottom of the nail falls down.
  • the rotation of the order drum 43 by 180 ° causes the nail 41 to fall, since it is driven by the compressed air, with the rivet 42 at the front, inside the feed line 48 and 49, to the rivet gun 5, which is provided with a positioning device 6 on the side and outside .
  • the movable part of this device 6 which consists of two levers 68 and 68 ', which are moved by a rotor 69 and which are guided by a cam guideway 64,, when pushed back, causes the spring pliers 52, the body of the rivet 42, which comes from the pipeline 49 to grab.
  • a subsequent feed control of the rotor 69 brings, through the play between the levers 68 and 68 'and the cam 64, the spring pliers 52 with the rivets 42 with the nail 41 in front of the head 7 to the axis of the rivet gun, the tip of the nail being on the inlet opening 60 is directed.
  • the backward movement of the rotor 69 allows the nail to go into the opening 60 until it hits the tip of the head 7 with the ring of the rivet 42. At that moment, the spring wedge 61 is clamped to the pin of the nail, which in any case prevents it from coming out.
  • the spring pliers 52 leave the body of the rivet 42 and move laterally during the push-back to pick up a rivet again.
  • An oil-dynamic jaw device of the known type is attached to the nail of the received rivet and carries out the tearing at the command of the control panel, pulling back and pressing the rivet onto the predetermined seat.
  • the used nail taken up by compressed air, is brought through a pipe to a collecting container, which is located inside the base frame.
