Definitions

  • the known device must sequentially perform a plurality of cycles to pick up one bar at a time and deposit it in the drawing assembly, but then it must obviously stop for the whole time while the bars are being translated by the drawing assembly towards the working machine.
  • This entails a reduction in the efficiency and productivity of the machine, since, when the working cycle of the machine is finished, it is necessary to wait, with the machine stopped, until the feeder device again begins its cycle of picking up one bar at a time and positioning all the bars required in the drawing assembly of the machine.
  • the first magnetic means are associated with first movement means able to move them so as to raise the end parts of a plurality of bars with respect to the bundle.
  • the second magnetic means are able to sequentially unload a plurality of bars, picked up one at a time from the first magnetic means, in a pre-loading position so as to form a store with said plurality of bars.
  • the store is formed in a position aligned and external with respect to the loading position into the drawing assembly, and the insertion of the bars into the drawing assembly provides only a lateral translation.
  • - figs. 1-4 show a front view of one form of embodiment of the feeder device for bars according to the present invention in a sequence of its operating cycle;
  • - fig. 7 shows a lateral view of the device in fig. 6 used to remove bars from a bundle.
  • the device 10 is suitable to pick up, from a bundle of bars 12 lying at least partly in a housing seating 30 (see fig. 7), one or more bars 11 at a time to send to the working machine.
  • the housing seating 30 can comprise two, three or more pockets, possibly movable laterally, inside each of which bars 11 of the same size are disposed, but different from those in the other pockets.
  • the feeder device 10 is movable with respect to the pockets, or other housing seating for the bars 11, in order to move selectively according to the type or size of bars 11 to be picked up.
  • the feeder device 10 is mounted in this case on a supporting frame 18 and comprises first magnetic means 13 consisting of a first magnetic or electromagnetic element 14 disposed advantageously during use in proximity with one end of the bars 11 of the bundle 12.
  • the first magnetic means 13 comprise two or more magnetic or electromagnetic elements 14, disposed at several distinct points on the length of the bars 11, advantageously near their front ends.
  • the magnetic element 14 can be correctly positioned in correspondence with the desired bundle 12 from which the bars 11 are to be removed .
  • the magnetic element 14 is lowered towards the bundle 12, by means of the first actuator 15, to take the lower face thereof, comprising the attractive surface, to a position such as to exert an effect of magnetic attraction on the ends of the bars 11 located at the highest part of the bundle 12.
  • the magnetic element 14 is returned upwards, magnetically lifting the ends of one layer of bars 11 disposed adjacent to each other so as to form substantially a plane (fig. 1).
  • the first magnetic element 14 is mounted on the relative arm 31 by means of an articulated joint 42, which allows it a certain freedom of oscillation in order to facilitate the picking up of the bars 11 even if the pockets have a curved and/or shaped bottom, and even if only a few residual bars 11 have remained at the bottom of the pockets.
  • second magnetic means 21 are activated, which comprise a second magnetic element 22 mounted at the end of a second actuator 23 mounted, in turn, on the supporting frame 18 (fig. 2).
  • the second magnetic means 21 comprise two or more magnetic elements 22 able to act at two or more distinct points on the length of the bars 11.
  • the bar 11 is released due to the interference on the bar 11 exerted by a stop element 50 during the movement of retraction of the second magnetic element 22.
  • the position of the stop element 50 can advantageously be regulated at least in height according to the diameter of the bars 11 being worked, so as to create a housing made to size for said bars 11.
  • the thruster element 65 comprises a front edge 62 facing upward, the upper end 63 of which is conformed as a lead-in slide to help the bars 11 to dispose themselves on the supporting surface 61, which in this case is substantially horizontal.
  • the supporting surface 61 of the thruster element 65 is disposed substantially parallel but lying on a plane below the position of the loading plane for the bars 11 into the drawing assembly 27, which substantially corresponds to the upper surface of the lower roller 26b.
  • the thruster element 65 When the first bar 11 has been released, the thruster element 65 performs a first movement towards the inside — direction 70 — to move the bar 11 to an inner waiting position, defined by the position of a substantially vertical abutment plate 64, and then returns backwards to position itself in a position to receive a new bar 11.
  • the abutment plate 64 is substantially positioned flush with the lateral edge of the rollers 26a, 26b of the drawing assembly 27.
  • the second magnetic element 22 performs a new cycle of picking up a bar 11 and unloading it onto the supporting surface 61 of the thruster element 65 when the latter has returned to its external start-of-cycle position.
  • the thruster element 65 returns towards the inside, that is, towards the rollers 26a, 26b, so as to locate the new bar 11 in a stand-by position near the abutment plate 64 and adjacent to the first bar 11.
  • the cycle to pick up, unload and laterally translate the bars 11 can be repeated a desired number of times so as to form the desired store, also according to the diameter of the bars 11, the configuration of the rollers 26a, 26b, and the requirements of the machine and the working cycle.
  • the whole accumulation assembly 60 first performs a movement upwards — direction 73 — so as to locate the bars 11 in a position aligned with the upper surface of the lower roller 26b, immediately above the upper end of the abutment plate 64.
  • the upper roller 26a is then positioned in the correct position to create a guide channel according to the diameter of the bars 11.
  • a mobile abutment is provided, able to create said guide channel.
  • the accumulation assembly 60 then performs a movement of lateral translation towards the rollers 26a, 26b, so as to thrust the bars 11 all together between the rollers 26a, 26b.
  • an abutment roller 67 is advantageously present, which prevents the bars 11 from sliding beyond the loading position between the rollers 26a, 26b.
  • the accumulation assembly 60 returns to its lowered, end-of-cycle position (fig. 1) and the feeder device 10 can start a new cycle to form the store, as previously described.
  • a guide roller 39 is shown, in this case solid with the stop element 50 and disposed immediately above the lower roller 26a of the drawing assembly, the function of which is to guide the movement of the bars 11 when they are translated by the accumulation assembly 60 to the loading position between the rollers 26a, 26b.
  • the position of the guide roller 39 can be regulated at least in height according to the diameter of the bars 11 being worked.
  • the abutment plate 164 is associated with a positioning actuator, and remains stationary during the whole cycle to form the store of bars 11, so as to define the stop position thereof near the gap between the rollers 26a, 26b of the drawing assembly 27; during the loading step, the abutment plate 164 is raised, or lowered, allowing the bars 11 to be inserted in a removal position between the rollers 26a, 26b.
  • header element 37 can be seen, associated with a movement actuator 38.
  • the function of the header element 37 is to align the bars 11 with respect to each other, by acting repeatedly against the relative ends, after they have been picked up by the first magnetic element 14 and are kept raised with respect to the bundle.
  • the header element 37 by selective activation of the movement actuator 38, performs some beating cycles against the ends of the bars 11, equalizing their longitudinal disposition so as to facilitate the subsequent step of loading into the drawing assembly 27 and the working to be carried out afterwards .
  • the heading operation can be performed both when the bars 11 are held raised by the first magnetic means 13, and also on bars 11 which have already been unloaded onto the accumulation assembly 60.
  • a sensor may be provided which signals the fact that the second magnetic element 22 is performing a purposeless travel without meeting bars 11, giving consent for a new descent of the first magnetic element 14 towards the bundle of bars 11 to perform a new pickup.
  • Another variant may provide that there are fixed stop elements present above the first magnetic element 14, which allow to discharge the bars 11, and make them fall back into the relative bundle, that have remained gripped on said first magnetic element 14 once the working cycle of the machine has been stopped. This discharge is obtained by raising the first magnetic element 14 by an extra travel beyond said stop elements. The discharge of the bars 11 can also be obtained, in the event of electromagnetic elements being used, by temporarily deactivating electric feed to said first magnetic element 14.
