Definitions

  • the present invention relates to a oscillating transfer and feeding apparatus an to a method for facilitating the transverse insertion of steel and/or metal bars in general, having any cross-section, on a transfer and feeding disk or disks and/or chains for automatic machines, particularly for electric welding and/or automatic bending units, according to the preambles of claims 1 and 2 and 11 and 12 respectively.
  • the invention is particularly advantagious for the unit for transverse feeding of single metal bars which are straight and/or bent and which have cross-sections of any size and a regular and/or irregular geometric shape (in the specific case, for steel bars with an enhanced surface, which are suitable to provide electrically welded metal nets and/or three-dimensional lattice-like cages used to reinforced concrete castings in the building sector and/or in the field of building prefabrication).
  • the invention consists in providing a mechanical transverse single bar feeder apparatus which is capable of oscillating alternately in a radial direction with respect to the rotation axis of the toothed disk and is contoured for correct individual distribution of bars.
  • the aim of the invention is to facilitate transverse insertion on the perpendicular toothed feeder disk, provided with peripheral seats, each of which accommodates a profiled element, for a bar of any sort, even having an irregular cross-section, and to ensure at the same time that only one bar is contained in each of said seats, in order to avoid overlaps which would cause hindrances and stops of the automatic manufacturing machines.
  • a method for feeding metallic bars in a transverse direction which uses at least one toothed disk which has, on its circumference, a plurality of recessed and contoured seats, which are suitable to accommodate only one profiled element for each seat and which, by rotating, releases one bar at a time for correct feeding of the automatic machine (in the case of electric welding to form metal nets).
  • Said seats are provided for specific sectional dimensions of the bars, so that as the sectional dimensions or geometric shapes of the bars vary, it may happen that two profiled elements (if they have a small diameter) may become inserted in a single seat, or a bar having an irregular cross-section might be unable to enter said seat by gravity.
  • the step for distribution and individual feeding of the bars in a transverse direction is interrupted even if the circumferential contoured seats of the feeder disk of the individual type are the type that is ideal for the cross-section of the profiled element, due to the accumulation of multiple profiled elements and to the poor positioning of the first profiled element at the seat of the transfer disk.
  • EP 0 411 688 A1 describes an apparatus with conveyor means for the transport of bars, the apparatus being constituted by a so-said rack, followed by a chain conveyor means.
  • the rack comprises a saw-teeth-shaped stationary bed, intersected by a set of mobile, also saw-teeth-shaped, rakes, and by a set of conical, motor-driven rolls, which are aligned with the chains of the conveyor unit.
  • the present invention provides for an oscillating transfer and feeding apparatus for facilitating the transverse insertion of metal bars having any cross-section as defined in claims 1 and 2.
  • the present invention provides for a method for facilitating the transverse insertion of metal bars having any cross-section as defined in claims 11 and 12.
  • the aim of the invention is achieved by means of the method and the corresponding oscillation apparatus for facilitating the transverse insertion of steel and/or metal bars in general according to claims 1, 2, 11, and 12.
  • An object of the present invention is to avoid interruptions and jammings in the individual transverse feeding of straight and non-straight metal bars on automatic production machines, such as for example units for automatic electric welding to form metal nets suitable for the building sector and/or automatic machines for forming three-dimensional lattice-like metal cages and/or bar bending machines.
  • the applied method uses the oscillation and/or vibration of the rotating disk (which has circumferential seats), suitable for the individual lateral movement of the metal bars in order to feed the automatic machines, to facilitate the insertion of the bars in such seats.
  • the oscillation or vibration is applied to the disk rotation shaft, so that the alternating oscillation occurs angularly with respect to the axis, forward and backward, or also in a rectilinear direction, causing the oscillation of the entire conveyor disk supporting unit.
  • the same result is achieved also with a similar oscillation which is applied, simultaneously with the oscillation of the disk or not, to the unit for collecting or conveying metal bars while waiting for insertion on the seats of the rotating disk for the individual movement of the bars.
  • the alternating oscillation movement of the shaft of the rotating disk with circumferential seats is achieved by using methods which are known to operators in the field, such as a mechanical eccentric system which acts directly or indirectly on the axis of rotation of the individual transfer disk, in order to perform an angular oscillation, an electromagnetic system, an electromechanical system, an electronic system, acting on the control of the actuation motors, a pneumatic system acting with suitable actuators on command on said bar supporting rotating disk or on its rotation shaft and/or on the magazine; a vibration system applied to the bar supporting disk and/or to the bar collection unit ahead of the disk, a mechanical system for actuation of the disk, whose unit rested on elastic supporting springs is made to oscillate on command by suitable actuators in order to cause the oscillation or vibration of the bar receiving seat of the disk.
  • a mechanical eccentric system which acts directly or indirectly on the axis of rotation of the individual transfer disk, in order to perform an angular oscillation
  • an electromagnetic system an electromechanical system, an electronic system, acting on the control of the actu
  • the invention achieves advantageously and automatically on command, and is adjustable as the mechanical and geometric characteristics of the metal bars to be conveyed vary, the function of picking up one bar at a time from the container by gravity, and conveys it laterally by means of at least one disk and/or chain which is arranged at right angles to said bars and has, on its circumference, a plurality of contoured seats which are suitable to receive one bar at a time.
  • the metal bar which arrives from the container by gravity, is facilitated in entering the peripheral contoured seat of the underlying disk by virtue of the back-and-forth oscillation of said disk (in an angular direction with respect to the rotation of the disk or in another direction of oscillation). Said bar is conveyed on command, by virtue of the systems for automating and actuating the shaft on which the disk is mounted, from the position for falling from the upstream container (by turning the disk), to a position for unloading by gravity on an appropriately provided conveyance and feed chute of the automatic machine (for example an electric welding unit or a bending machine).
  • the automatic machine for example an electric welding unit or a bending machine
  • Another variation of the present invention is the possibility to use one or more chains which are particularly suitable, with teeth contoured for conveying metal bars, as a replacement of the contoured disks.
  • the chain can oscillate back and forth in order to ensure the pick-up of a single profiled element per tooth from the upstream hopper, and unload on command one profiled element at a time onto the machine feed chute.
  • the invention is highly versatile in use, since the conveyor disk and/or the chain with the contoured seats are adapted and are suitable for many types of cross-section of the metal profiled element.
  • the present invention solves advantageously the drawbacks observed with current systems by using the oscillations or vibrations of the devices suitable to receive the metal bars and their lateral conveyance individually and in an assured manner in order to ensure feed continuously the automatic production machines without interruptions.
  • the device for lateral transfer of the bars is the rotating disk (2), which is actuated on command by a suitable gear motor (9) and an extension (10) for motion transmission which is provided with suitable flexible articulations for transferring motion, even by virtue of successive elements, to the disk supporting axis (1).
  • Said disk (2) or multiple disks mutually aligned and parallel disks if particularly long metal bars are used, has, on its circumference, hollow contoured seats (3) which are equidistant and have an irregular shape, which however is suitable to allow the insertion of the bar (4), and then its pickup by gravity, from an upstream position from a suitable magazine (5) which lies above said rotating disk.
  • the disk turns about its own axis (1) and in its movement it entrains the individual profiled element from a pick-up position to a position for unloading onto an appropriately provided chute (6) by gravity, freeing the seat of the disk for another cycle.
  • the oscillation of the disk can also occur in a different manner, for example by oscillating in an alternating manner the disk also in another direction which is different from the radial rotation direction, always using an eccentric device.
  • the oscillation or vibration movement of the disk (2) can occur with other means which are known to the person skilled in the art (for example with the use of elastic springs which support the entire unit, or other equivalent solutions).
  • the oscillation and/or vibration of the insertion seat (3) of the disk (2) increases the dimension of its access port and therefore facilitates the fall of the first overlying profile.
  • One possible variation to the present invention consists in using the oscillation or vibration (performed simultaneously or not) with the oscillation or vibration of the rotating disk, in moving with alternating jolts the metal bar magazine upstream. In this manner, by shaking the magazine, the alignment of the bars inside it is improved, thus sorting them with respect to the gravity outlet.
  • the second possible variation to the present invention consists in using one or more chains (12) with particular teeth for conveying metal bars (4).
  • the chain is moved on command, by means of two toothed disks (13, 14), from a position for picking up the bars from the hopper (5) to a position for individual unloading onto the chute (6).
  • said chain is moved back and forth alternately and repeatedly, by producing the angular oscillation of the driving toothed disk, in order to allow the exact insertion of the bar transversely on the seat of the tooth.
