Definitions

  • the invention relates to an automatic soldering device for soldering jewelry chains, in particular flexible jewelry chains, with chain parts, in which the chain part to be soldered is fed to a holding pliers and the jewelry chain end link is brought to this chain part by means of pliers that can be moved by means of a carriage, whereupon the jewelry chain end link is soldered to the chain part and then the carriage moves back according to the chosen jewelry chain length, the jewelry chain is separated at the end point by means of a separating device and the resulting jewelry chain end link is fed back to the soldering point.
  • the object of the invention is to provide an automatic soldering machine which ensures the prerequisite for the soldering of such flexible chains, namely the correct grasping of the end link and its equally correct cutting. This is achieved in an automatic soldering machine of the type described (DE-A-33 02 208) by an arrangement in which the separating device is arranged next to the pliers on the slide and on the slide a sensor scanning the contour of the jewelry chain is attached, and in a slide drive for the slide is also provided which moves the slide into a predetermined end position dependent on the sensor position.
  • the chain length is therefore not always constant when using the automatic soldering machine according to the invention, but can, if the prerequisite is that the chain link is cut in the middle, fluctuate by half a chain link length.
  • the end member is now correctly grasped and the necessary and desired shape of the end member is brought about by the correct separating cut, this correctly shaped end member can now be brought up exactly and in the desired manner to the counterpart to be soldered and with it without rejects or a malfunction of the machine must be feared, be soldered. This not only results in a very satisfactory, clean soldering work, but also very high production numbers can be achieved without any disruption.
  • the pliers can simultaneously serve as a cutting edge for a cutting knife.
  • the sensor In order to be able to determine the position of the chain link to be detected as precisely as possible, the sensor should sense the contour of the chain link following the end link.
  • This sensor can be a sensor lever, in the swivel range of which an inductive or capacitive displacement sensor is inserted, or the position of which is indicated optoelectronically.
  • the feeler element of the feeler lever is expediently adapted to the chain shape to be sensed. In the case of the usual jewelry chains, it is generally sufficient to have a tracing edge which extends transversely to the chain longitudinal extension.
  • the feeler lever is expediently connected to an air-impact baffle plate, as a result of which the feeler lever is always pressed onto the chain with a constant, sufficient pressure.
  • the sensor can also be an optoelectronic scanning device, starting with simple light barriers that react to the contour of the chain with light / dark control or signal openings in the chain, to optoelectronic devices that work with laser light and can also determine the contour holographically .
  • the sensor for the optoelectronic scanning device can be a light guide brought up to the chain link adjacent to the end link.
  • a magnetic probe is also conceivable as a sensor for ferromagnetic material.
  • stepper motor As the carriage drive, in particular also when the switching device is a programmable small computer.
  • This small computer can give the stepper motor the necessary impulses for a certain chain length and then, depending on the position of the sensor, add necessary plus or minus contacts for the correct position of the pliers or the disconnecting device.
  • this chain link 1 In order to be able to cut the chain link 1 of the round link chain according to FIGS. 1, 2 correctly in the middle, as indicated by the arrow 2, this chain link 1 must be detected, as indicated by the dash-dotted lines 3.
  • a sensor shown in the drawings as a sensor lever 4, is used with a sensor link 5.
  • This sensor lever 4 is a two-armed lever mounted on a bearing block 6 which is arranged on a carriage 8 which can be displaced in the direction of the double arrow 7.
  • an inductive displacement sensor 9 In the swiveling range of this feeler lever 4 there is an inductive displacement sensor 9, which signals the respective position of the feeler lever 4 to a small computer 10.
  • Pliers 12 are also arranged on the carriage 8, as is a separating device (arrow 13).
  • the separating device 13 is in this case directly adjacent to the pliers 12.
  • a chain tensioning device 14 is shown, as well as, beyond, a holding tongs 15 and a soldering device 16.
  • the carriage 8 is displaced by means of a carriage drive 17, which gradually moves the carriage 8 as a stepping motor.
  • air nozzles 18, 19 act on the feeler lever 4, which either press the feeler lever 4 onto the chain (18) or lift it off it (19).
  • FIG. 7 shows the initial stage of the soldering process.
  • the chain part that is to be soldered to the jewelry chain 20 is inserted in the holding pliers 15.
  • the automatic soldering machine After the jewelry chain 20 has been carried out by the automatic soldering machine, it is manually soldered to this chain part in the holding pliers 15.
  • the automatic soldering machine After tensioning the chain 20 by the tensioning device 14, the automatic soldering machine is then in the position shown in FIG. 7, the feeler lever 4 being pressed onto the chain 20 by means of the air nozzle 18.
  • the immigration of the feeler lever 4 by moving the carriage 8 over the stepping motor 17 is shown in a detailed illustration in FIG. 9. It is assumed here that the feeler lever 4, as shown in the broken line, rests on the surface of the chain link 21.
  • the feeler lever 4 By moving the carriage 8 and thus simultaneously by moving the feeler lever 4 in steps 22, The feeler lever 4 gradually moves into the recess of the contour of the chain 20 until it has reached its lowest position.
  • the small computer 10 gives a pulse to the pliers 12, which then detects a link 1, 11, 21 of the chain 20 as shown in FIGS. 1 to 6.
  • the severing device 13 receives the command to sever the chain 20, as a result of which this detected chain link 1, 11, 21 is severed in the middle.
  • the holding pliers 15 open so that the fully soldered part falls out.
  • the chain link half not gripped by the pliers 12 also falls out of this chain.
  • the carriage drive 17 now receives, again via the small computer 10, the command to approach the holding tongs 15, as shown in FIG. 8.
  • the soldering device 16 is actuated so that the actual soldering process begins.
  • the carriage moves back into the position shown in FIG. 7.
  • the feeler lever 4 is lifted off the chain via the air nozzle 19.
  • the feeler lever 4 is again pressed onto the chain via the air nozzle 18, after which the process described above is repeated with the immersion of the feeler lever between the two chain links 21.
  • This pivoting movement of the feeler lever 4 is signaled here by the inductive displacement sensor 9.
