Definitions

  • the present invention relates to a method for feeding metal bars in a controlled number to an operating unit.
  • the invention may be applied, for example, to systems for cutting and/or bending metal bars to be used for reinforcement of concrete.
  • Some apparatuses make use, for example, of cutting benches in which bars of standard length are cut into desired lengths.
  • a cutting bench basically envisages a resting surface on which the bars are fed to undergo cutting, and cutting equipment, set at one end of the bench, for cutting the bars after they have been fed forward on the bench for a desired length.
  • Usually provided upstream of the cutting equipment are means for feeding the bars on the bench.
  • the Italian patent No. IT1360977 filed in the name of the present applicant describes a device for feeding in a completely automatic way a cutting bench of the type referred to above.
  • the device described in this patent is able to feed the metal bars in a controlled number from a first, pick-up, position, in which the bars are grouped in a bundle, to a second position for delivery of the bars to the means for feeding the cutting bench.
  • US5,357,778A describes a solution of prior art wherein a pre-defined number of bars are transferred, all at the same time, from a magazine to an intermediate storage compartment, from where they picked up, counted and transferred towards an operating machine, in a direction transverse to their longitudinal axis.
  • the object of the present invention is to provide a system for feeding metal bars in a controlled number to an operating machine that will be configured for providing transverse feeding of the bars and that will be able to operate in an efficient and reliable way.
  • Figure 1 represents a system for feeding metal bars in a controlled number to an operating machine.
  • the operating machine may be a bending machine, a cutting machine, a painting machine, a threading machine, or the like.
  • the system envisages a magazine 20 configured for storing a large number of bars, divided within the magazine, in respective compartments, by length, diameter, and/or material.
  • the magazine may, for example, be obtained via a framework defining a series of compartments that present in the horizontal plane a prevalent extension oriented along which are the bars that are housed therein and that are set alongside one another in a direction transverse to the their longitudinal direction.
  • transverse and longitudinal directions mentioned are defined with respect to the orientation of the bar within the system, and on the other hand also the directions themselves of the system are defined with respect to the orientation of the bars within the system. Consequently, also the simple indication of longitudinal direction or transverse direction already in itself indicates uniquely which direction is considered irrespective of whether it refers to the bars or to the device of the system that handles the bars.
  • the system envisages a station for handling the bars 22, which is equipped with a handling and counting machine 1 and has, right up against said machine, an intermediate compartment 24, into which are unloaded the bars that have been picked up from the magazine.
  • a pick-up and movement apparatus 26 for example a gantry structure equipped with one or more gripper devices, performs the function of picking up the bars from the magazine 20 and unloading them into the intermediate compartment.
  • the handling and counting machine of the station in question basically performs the functions of picking up the bars from the intermediate compartment, counting them, and feeding them to the operating machine in a transverse direction.
  • the handling and counting machine is of a type suited for being supplied by gravity, i.e., according to a modality where the bars access the machine as a result of the force of gravity acting on them.
  • the machine in question has one or more transfer members, which operate directly on the bars gathered by gravity up against the machine and which move the bars in a transverse direction.
  • the above machine may be of different types.
  • the handling and counting machine in question is configured for picking up just one bar at a time, it being meant thereby that it is configured for engaging the individual bars in sequence. As a whole, the machine may in any case be operating also on a number of bars simultaneously.
  • the intermediate compartment 24 performs, in this arrangement, the function of feeding the bars to the aforesaid machine. It has a raised surface 241, preferably horizontal, which is in communication with the transfer members of the handling machine via an inclined plane 243.
  • a containment plate 245 is associated to the above two surfaces, namely the raised surface 241 and the inclined plane 243.
  • the aforesaid plate is set in an opposed position with respect to the inclined plane 243 and, with a portion thereof, extends as far as on top the horizontal surface 241 so as to define a wall designed to provide lateral containment of the bars supported by this surface.
  • the above plate At its portion opposed to the inclined plane 243, the above plate is set at a distance from the latter so as to define a restricted channel, the section of which is such as to enable passage of just one bar at a time, thus forcing the bars to arrange themselves in an orderly way in a row and advance in this condition towards the machine 1.
  • the inclined plane 243 could even not be present, in which case the bars gather directly against the transfer members of the machine.
  • the bottom of the compartment 24 may form part of a vibrator device having the function of favouring both disentangling of the bars and displacement of the latter towards the machine 1.
  • the station 22 on the side opposite to the intermediate compartment 24, has an inclined plane 27, unloaded onto which are the bars that have been picked up and counted by the machine 1.
  • the inclined plane 27 is configured for transferring the above bars directly to the operating machine or else to conveyor means upstream thereof.
  • a series of arms 29 are positioned flush with or underneath the inclined plane 27 and are hinged - for example to the same structure that supports the inclined plane 27 - about one and the same longitudinal axis, so as to be simultaneously brought into a position raised above the inclined plane 27 in order to stop the bars from sliding down the plane 27.
  • the arms 29 may be activated for the purpose, for example, of accumulating along the plane 27 all the bars that the machine 1 has had to pick up from the intermediate compartment 24 so as to transfer them to the operating machine all together.
  • the station 22 described above may envisage different structural configurations.
  • it has a single metal framework, which defines the intermediate compartment 24 and the inclined plane 27 and carries the machine 1 and the arms 29 together with the respective actuation means.
  • this comprises a pick-up device including a rotary drum 6, which is made to rotate (via motor means not illustrated) about its own axis 6a and is set alongside the intermediate compartment.
  • the rotary drum 6 has a magnetic element 10, which is set at the periphery of the drum and defines a housing 11 sized for receiving only one bar 2 inside it. It is also possible to envisage that the rotary member will present a number of magnetic elements 10 angularly spaced apart from one another, in which case at each revolution of the drum 6 a number of operations of picking-up of bars is performed that is equal to the number of the magnetic elements provided. Moreover, instead of the magnetic element or elements, the drum 6 could also envisage members of some other type, in particular mechanical members, for example a hook, a cam, etc.
  • each rotation of the rotary drum entails picking up a controlled number of bars (for example, of just one bar).
  • a system usually envisages handling bars of different diameters.
  • the system preferably envisages a counter (not illustrated), for example an optical counter or else a mechanical-lever counter, which is able to count the bars that pass in front of it, in a position prior to unloading of the bars.
  • a counter for example an optical counter or else a mechanical-lever counter, which is able to count the bars that pass in front of it, in a position prior to unloading of the bars.
  • the means that control activation and the de-activation of the magnetic element temporarily de-activate the magnetic element in order to enable unloading of the bar that has been picked up. This may be obtained either by causing interruption of electrical supply to the electromagnet whenever this reaches a pre-set position or using the counter as de-activation sensor, possibly after a predetermined delay.
  • a sort of scraper element which causes dropping of possible bars that have accidentally remained adherent to the magnetic element and are in excess with respect to the desired number to be picked up at each passage of the magnetic element on the bundle of bars.
  • a number of magnetic elements with respective housings sized according to different bar diameters, these magnetic elements being activated in a selective way according to the type of bars on which it is necessary to operate.
  • Unloading of possible excess bars that have been picked up may also be obtained by de-activating the magnetic element following upon the signal received from sensor means for detecting the number of bars that have been picked up. Return of the excess bars into the bundle is obtained by de-activating the magnetic element 10 and possibly reversing rotation of the rotary member.
  • the drum 6 is equipped with adjustment means, for example of a mask type, which enable adaptation of the housing associated to the magnetic element to different values of bar diameter.
  • the magnetic element does not necessarily have to be an electromagnet, but as an alternative there may also be envisaged permanent magnets associated to which is a respective mobile mask, which can be operated for covering the corresponding magnetic element so as to de-activate it.
  • the magnetic element or else the drum itself may be of a removable quick-mounting type in order to enable interchangeability with similar elements and render the system readily adaptable to the various applications, for example, for picking up bars of different diameters.
  • De-activation of the magnetic means may be performed either to facilitate release of the bars once they have been picked up to deliver them to the supply means set downstream or for unloading possible excess bars again into the bundle in the case where the number of desired bars has already been reached. Management of the possible excess bars will in any case depend upon the specific circumstances. In the case, for example, where the cycle subsequent to the one that has just terminated envisages supply of bars of the same type, the bars that have already been picked up can be withheld by the magnetic means until start of the next cycle without any need to unload them again into the bundle.
  • the means so far described operate for picking up the end portion of the bar (but the bar could be picked up, of course, in some other point, for example at the centre instead of at the end).
  • the handling machine moreover has purposely provided means for lifting completely and picking up also the remaining part of the bar so that it is then possible to move it in a transverse direction.
  • the system described herein has one or more additional drums 6', which are also provided with respective magnetic elements 10' and are rotatable about respective axes of rotation substantially aligned with the axis of rotation of the drum 6.
  • the number of additional drums may clearly vary according to the requirements of the specific applications. In particular, with bars of small diameter the additional drums may be in a number equal to or higher than four.
  • the drums 6' have the function of engaging corresponding portions of the bar that has already been picked up by the drum 6 and of raising these portions further as a result of the movement of rotation of the drums 6' themselves so that, at the end of the operation carried out by the entire set of drums 6 and 6', the bar is completely raised and separated from the other bars.
  • the drum 6' set immediately downstream the drum 6 has the function of engaging, via its element 10', the portion of the bar that has been picked up by the drum 6, which, as a result of the movement of rotation of the latter, is brought into its immediate vicinity, and of raising the aforesaid portion further via its own movement of rotation.
  • drums 6 and 6' must clearly be synchronised so as to intervene on one and the same bar in sequence.
  • the first drum 6' must bring its respective magnetic element 10' up to the bar engaged by the drum 6 when this has already raised it sufficiently, and, likewise, the second drum 6' must bring its magnetic element 10' up to the bar when the first drum 6' has raised it sufficiently.
  • the movement of rotation of the drums 6 and 6' brings about not only raising of the bar engaged but also lateral displacement thereof. Consequently, in operation, the various magnetic elements 10 must arrange themselves in given mutual angular positions that make it possible to follow the above angular displacement, also taking into account the deformations due to bending that the bar may undergo during this step.
  • the drums 6 and 6' are controlled by one and the same shaft driven by an electric motor, and are mutually oriented according to fixed angular positions, which are determined during a step of calibration of the system.
  • the drums 6 and 6' may instead all have the same angular position, and not be staggered, with respect to their members for picking up the bars.
  • a corresponding series of lifting devices may operate, which are provided with grippers designed to receive the individual bars that have been picked up by the drums and feed them, either individually or all together, directly to the operating machine.
  • the grippers may envisage a vertical adjustment so as to facilitate picking-up of the bars by the various drums 6 and 6' , and in a way such that the bars that have gathered can then be positioned according to a substantially horizontal arrangement.
  • the system may in any case also envisage members of some other type, for example mobile supports, which are preferably provided with appropriate grooves for ensuring an orderly arrangement of the bars thereon.
  • the above supports may, for example, be constituted by a plurality of rotary screw members.
  • roller tracks may also be envisaged, or else supports or brackets variously shaped in the form of a U, a V, an L, etc.
  • the disentangling means may be constituted by one or more supports 16', which are slidable in a direction substantially parallel to the longitudinal direction of the bars gathered in the bundle and act on the bar that is picked up by the drum 6 so as to raise it progressively and separate it completely from the other bars.
  • the supports may have a fork-like structure so as to be able to constrain laterally the bars that have been engaged.
  • the drum 6 could also be set in a position corresponding to a central region of the bundle of bars, and in this case the disentangling means comprise slidable supports, which are arranged on both of the opposite sides with respect to the central drum and are mobile, in opposite directions, from the central drum to the corresponding ends of the bars.
  • the slidable supports in question perform the same function of lifting the bars progressively from the bundle so as to extract them completely therefrom.
  • the slidable supports mentioned above have also the function of supporting the bars before these are then supplied to the operating machine. Consequently, the slidable supports in question will have to be in a number such as to make it possible to support the entire bar as this is lifted up from the bundle, preventing it from undergoing excessive bending. It is evident that only some of the supports will reach the end of the bar, whereas the others will stop their movement in respective positions along the bar, precisely in order to enable support thereof as described.
  • a lateral structure for example a set of grippers or a series of V-shaped elements, onto which the bars are unloaded as the slidable supports lift them up and separate them from the other bars.
  • the bar or bars that have been separated can then be carried to the operating machine directly by the slidable supports or else by the further elements onto which the bars are unloaded.
  • the handling and counting machine 1 operates by picking up a controlled number of bars and moving them in a transverse direction so as to feed them to the operating machine.
  • the system of Figure 8 differs from that of Figure 1 in that the handling and counting machine of this system comprises a rotary screw member 36 that is oriented in a direction transverse to the bars housed in the intermediate compartment, and in that it is set with its end facing the bars that positions itself directly at the end of the inclined plane 243.
  • the outer thread portion of the member as a result of rotation thereof, pushes the bars laterally, in a direction opposite to the position of the intermediate compartment, moving them in a transverse direction and separating them from one another.
  • disentangling means of the same type as what has been described above, which, in particular, act on the bar that has been picked up by the screw member so as to separate it completely from the other bars.
  • drums 6' and the grippers 12' may even find themselves carrying out a function proper of disentangling of the bars, in the case where these are entangled, for example in the cases where the bars are of a very small diameter. This function may become important in the embodiments of the system where there is absence of any element, such as the plate 245, designed to convey the bars towards the machine 1 in an orderly way.
  • a preset number of bars comprised within a given range, is accumulated within the intermediate compartment.
  • the above range has been selected on the basis of the maximum number of bars that can be handled by the operating machine in a single cycle.
  • the lower limit of the range is defined by a number equal to a multiple of the aforesaid number of bars per cycle of the operating machine, with a multiplying factor of 2
  • the upper limit is defined by a number equal to a multiple of the aforesaid number, with a multiplying factor of 20.
  • the bars accumulated in the intermediate compartment then gradually reach, by gravity, the transfer members of the handling machine 1.
  • the present applicant has set himself the aim of providing a condition where the handling machine 1 is able to operate at the service of the operating machine downstream for a number of cycles thereof in a continuous way and without any interruption for supply of new bars.
  • the compartment 24 can operate as a temporary magazine for the bars.
  • it since it is located immediately adjacent to the operating machine, it is able to supply the operating machine with the bars immediately and moreover for a number of working cycles, thus preventing any need for the movement means of the system to perform displacements over long distances, at each cycle, from the main magazine 20 to the operating machine.
  • the intermediate compartment is able to contain a number of bars sufficient to handle an entire batch of bars required by the operating machine. In other applications, to complete the batch it may, instead, be necessary to supply the compartment with new bars by picking them up from the main magazine.
  • Supply of the bars to the intermediate compartment may be performed at different moments according to the requirements of the specific applications. This step may in any case be carried out in masked times, for example during actual operation of the machine 1 for feeding the bars to the operating machine.
  • supply of new bars to the compartment takes place when the bars reach a number equal to or a little above the aforesaid maximum number of bars that can be handled in one cycle by the operating machine. In this way, it is guaranteed that the handling and counting machine will be always in a condition of being able to meet the requirement of the operating machine.
  • the latter may be equipped with a device for measuring the weight or else with a sensor device, for example of an optical type, for measuring the level of the bars in the compartment 24.
  • the apparatus 26 of the system is provided with members that are able to grip and pick up from the magazine, all at the same time, a number of bars practically corresponding to the number to be accumulated in the intermediate compartment 24.
  • These members may be gripper members, appropriately sized so as to be able to grip the number of bars envisaged, or else magnetic members configured for generating a magnetic force such as to cause the number of bars in question to adhere thereto.
  • the gripper members are configured for picking up the bars preferentially in a central region and moving away from one another so as to spread out over the length of the bundle of bars that is being picked up. The present applicant has found that this action by the gripper members affords the advantage of re-arranging the bars, disentangling them at least partially.
  • this will clearly be supplied with a number of bars greater than the number envisaged for the intermediate compartment, in the perspective of ensuring a plurality of supplies to this compartment and more in general in order to set the system in a condition where it is able to operate autonomously for a very high total number of cycles of the operating machine.
  • the magazine is supplied with a total number of bars that is at least a multiple equal to 40 of the aforesaid maximum number of bars that can be handled, in a single cycle, by the operating machine.
  • the aforesaid magazine may contain also batches of bars of different diameters divided by compartments.
  • the operating machine is a cutting machine or else a bending machine
  • the present applicant has been able to verify that the succession of steps of operation of the system remains basically the same irrespective of the diameter of the bars that are handled.
  • the operation of the system may be either completely automated or else may be governed by an operator through one or more control stations.
  • the system will anyway comprise a control unit designed to manage the information coming from the counter means regarding the number of bars picked up by the handling machine 1 and/or the number of bars present inside the intermediate compartment 24.
