Definitions

  • the present invention relates to a rivet feed, in particular a rivet feed for broken mandrel rivets.
  • Rivet feeds according to the prior art usually require complex constructions, as well as a supply with suction or blown air.
  • the delivery of broken mandrel rivets is particularly difficult because they have to be inserted into the riveting unit with the mandrel ahead.
  • the main focus of the broken mandrel rivet is on the mandrel side.
  • broken mandrel rivets with a very long aluminum rivet sleeve and an Al rivet mandrel have an unstable center of gravity and can therefore only be inserted with great effort.
  • a rivet feeder which has an inclined guide through which a rivet can slide and which ends in a rivet unit, the guide being at least partially closable by a slide.
  • the device is only suitable for feeding multi-point rivets.
  • a rivet feeder according to the invention comprises a funnel 10 of rotationally symmetrical design, which opens above a V-shaped channel 12.
  • the funnel is arranged parallel to the channel. It is particularly preferred not to make this funnel completely rotationally symmetrical. A possible rotational movement of the rivet to be picked up about its longitudinal axis can be prevented even better if the funnel has a rectangular or square cross section. To stop rotational movements of the rivet, it may also be sufficient to flatten the otherwise rotationally symmetrical, round-shaped funnel on one side, preferably on the side facing the groove. Under particularly favorable circumstances, this funnel 10 can also be dispensed with (see, for example, FIG. 6). The side walls of the channel 12 form an angle of approximately 90 ° with one another.
  • the V-shaped side walls of the channel 12 have perpendicular side walls 70, 72 parallel to each other at their respective outer ends (see FIG. 7). These additional vertical side walls prevent the rivet from jumping out of the groove 12 in a particularly reliable manner, in particular if the rivet previously has a rotating inherent movement about its longitudinal axis.
  • the channel 12 runs obliquely with respect to the vertical at an angle * alpha *. This is preferably 17 °. Depending on the shape of the rivet, it can of course be advisable to choose a different angle between 0 ° and about 30 °. Below the obliquely inclined channel 12 there is a further V-shaped channel 14, the side walls of which also form an angle of approximately 90 °.
  • This second channel serves as a contact surface for a riveting unit 16 and runs vertically. The degree of displacement of the channel 14 against the channel 12 and the angle of the side walls of this channel is of course to be chosen in accordance with the dimensions of the riveting unit 16.
  • the rivet feed comprises a slide 20 which can be moved back and forth by a drive device 22 in the plane of symmetry of the channel 12 at an angle ⁇ relative to the direction of the valley bottom of the channel.
  • the angle ⁇ can be adapted to the respective shape of the rivet, preferably it is 20 ° to 60 °, in particular 40 °.
  • the drive device 22 can work hydraulically, pneumatically or electromagnetically. It is advantageously designed as a compressed air cylinder which is reset by spring force. However, a spring-loaded magnetic switch (solenoid) can also be used.
  • the slide 20 can be brought into at least two positions, the groove being fully open in one of the positions (FIGS.
  • the slide advantageously has a shape that is adapted to the angle ⁇ and the angle at which the side walls of the channel 12 converge so that parts of the side edges of the slide abut the upper part of the channel 12. This results in a particularly advantageous shape for the slide 20, in which the slide 20 is rectangular in shape with beveled front edges (as shown in the drawings).
  • the front edge of the slide 20 is to form a triangular opening with the side walls of the groove 12 which is large enough for the mandrel of the rivet N1 to fit straight through, while the opening is much too small for the head of the rivet. It is thereby achieved that the rivet N1 can be held in a position in which the mandrel of the rivet N1 points exactly in a defined direction (see FIG. 1).
  • FIGS. 1 to 4 show different feed steps:
  • Fig. 1 shows the state in which a rivet N1 is held in the rivet feed.
  • the rivet feed can be moved in this state. In this state, it also does not require any energy supply.
  • FIG. 2 shows the state in which the riveting unit 16 bears against the rivet feed for rivet acceptance.
  • the slide 20 is pulled back by the drive device 22, as a result of which the rivet N1 falls directly into the mouthpiece bore 18 of the riveting unit 16.
  • the rivet N1 remains in the position shown in FIG. 3 stand. It is already centered in the mouthpiece of the riveting unit.
  • the rivet N1 immediately falls back and then lies against the mouthpiece in a manner suitable for processing.
  • the rivet handover is now complete. This process can be carried out just as perfectly with a linear movement.
  • the slide 20 is closed again by the movement device 22.
  • the next rivet N2 can already be fed from a rivet separating device.
  • the rivets are separated in the conventional manner after the storage section of a vibratory conveyor. Therefore, vibratory conveyors, accumulation section and rivet separator are not described in more detail. 4 only shows that the rivet from the rivet separator 26 must fall into the funnel 10 in the correct position (mandrel down).
  • the blind rivet slips in the shortest possible way into the mouthpiece opening of the rivet unit without being able to change its predetermined position.
  • the funnel 10 can be omitted if either the rivets from the separation already fall onto the channel 12 at the correct angle, or if the rivet is supplied by the rivets being conveyed in a hose using compressed air and then can also be released in the correct position above the gutter.
  • FIG. 6 Such an embodiment is shown for example in FIG. 6.
  • An outlet station 50 is mounted above the channel 12 in such a way that the rivets are released in the correct position directly above the channel 12 after they have passed a sensor 52 and a separating device 54.
  • a funnel is not required in this embodiment.
  • the remaining structure of the rivet feed corresponds to the rivet feed described with reference to FIGS. 1 to 5.
  • Only the channel 12 is designed according to the cross-sectional view in Fig. 7, i.e. the channel additionally has parallel walls 70, 72 on the side.
  • This embodiment with the additional vertical, lateral, parallel walls 70, 72 on the channel 12 is particularly advantageous because then the combination of slide 20, V-shaped channel 12 and its side walls 70, 72 simultaneously take on the technical effect of the funnel 10 can.
  • the slide should preferably not only extend in the V-shaped region of the channel, but also close the region between the lateral, parallel walls 70, 72.
  • This particularly preferred embodiment according to FIGS. 6 and 7 is particularly well suited for large-headed blind rivets. your However, a particular advantage lies in the fact that by omitting the funnel 10, a minimal size for the rivet feed unit can be achieved.
