Definitions

  • the present invention relates to systems for the treatment of metal bars, in particular bars for the reinforcement of concrete, of the type comprising:
  • a device for transferring metal bars of the type specified above is, for example, described in the patent No. EP-B-1 351 915 , filed in the name of the present applicant.
  • Systems for automatic loading of metal bars onto machines designed to carry out operations of various types on said bars are known from a wide range of documents, such as, for example, DE-AS-1 101 336 , IT 1 206 893 , EP-A-1 356 875 , EP-A-1 356 876 , EP-A-1 980 341 , EP-A-2 172 287 .
  • a further device of the type specified above has formed the subject of the Italian patent application No. T02010A000279 , filed in the name of the present applicant on April 12, 2010 and still secret at the date of filing of the present application.
  • the object of the present invention is to provide automatic loading of a predetermined number of metal bars onto an operating unit, guaranteeing that said operation is performed in a reliable, proper, and orderly way and using means that involve the occupation of a minimum portion of space in plan view, above all in the longitudinal direction of lie of the bars.
  • the subject of the present invention is a system according to Claim 1 and a method according to Claim 15.
  • Figures 1A, 1B the reference number 1 designates as a whole a system for bending metal bars, in itself of a known type.
  • Figures 1A, 1B are both plan views of the system 1, which comprises two bending units 2 (see also Figure 1C ), which each include a supporting structure 3, rotatably mounted on which is a bending disk 4 having a central spindle 5 and carrying an eccentric pin 6 for bending a portion of one or more bars B around the central spindle 5.
  • the axis 4A ( Figure 1C ) of the bending disk 4 is inclined with respect to the vertical direction. However, it would be equally possible to envisage that said axis is oriented vertically or horizontally, as is likewise well known in the art.
  • the two bending units 2 define a space 8 for receiving the bars to be bent, in which a number of bars can be received on top of one another in a plane orthogonal to the plane of bending of the bars.
  • the two bending units 2 are mobile on rails 9 in the direction L parallel to the longitudinal direction of lie of the bars B.
  • each bending unit provided within the casing 3 of each bending unit are motor means designed to govern movement of the bending unit along the rails 9.
  • the system for the treatment of metal bars is provided with an electronic control system, which governs, according to a pre-set program, the successive movements of the bending units 2 and of the corresponding bending disks 4 to obtain the different bends of a bar or of a set of bars subjected simultaneously to bending, with a view to obtaining any predetermined shape.
  • the bending units 2 can be of the type illustrated in Figures 1A and 1B , with a spindle 5 around which the bars are bent and with the contrast element 7, or else of the type with a spindle having a diametral slit that defines also the space for receiving the bars. In this latter case, one of the portions will possibly function also as contrast element.
  • Figure 1A shows the bar or bars positioned above the bending units prior to execution of a bending operation
  • Figure 1B shows the two bending units after the bending disks 4 have been rotated simultaneously through 90° to provide two bends at right angles at the ends of the bar or bars B.
  • the bending system 1 is illustrated herein with reference to the preferred embodiment of the invention, in which the device for automatic picking-up and feed of the bars is used for feeding the bars to said bending system.
  • the automatic device for picking up and loading bars that forms the subject of the present invention is likewise usable for feeding any predetermined number of bars also to operating units of a different type, for example, a unit for cutting bars into pieces of desired length or also for feeding the bars to a further waiting station, from which they are picked up only subsequently to be sent on for further treatments.
  • Figure 2 shows at an enlarged scale and in lateral view an embodiment of the stationary structure 30 moving on which are the two bending units 2, which define an inclined surface P coinciding with the plane of bending of the bars defined by the two bending units. Also visible in Figure 2 is one of the two contrast elements 7 associated to the two bending units.
  • the structure 30 carrying the two bending units 2 is set alongside a further stationary bench 10 carrying a chain-driven feed device 14 for feeding the bars to the receiving space 8 defined by the two bending units.
  • the stationary structure 10 supports, in an articulated way, a longitudinal distribution of transverse arms 11 defining an inclined surface Q via which the bars B are made to roll by gravity until they reach the receiving space 8 defined by the bending units.
  • a characteristic of the system according to the embodiment illustrated herein lies in the fact that it is able to pick up from a magazine (illustrated in greater detail in what follows) a predetermined number of bars and to feed said bars one after another into the receiving space 8 of the bending units, keeping them separated and set at a distance apart in such a way as to bring them up to the receiving space 8 in times that are close to one another but distinct.
  • Figure 2 shows four bars B while they are rolling towards the receiving space 8 of the bending units (not visible in Figure 2 ) in positions appropriately separate and set at a distance apart from one another.
  • the angle of inclination of the transverse arms 11 can be controlled by means of a fluid cylinder 12.
  • a fluid cylinder 12 it is possible to envisage a raised condition of the arms 11 in order to prevent any sort of interference between the latter and the bars that are bent in the bending units.
  • the bars B are fed to the inclined surface Q by means of a longitudinal distribution of chain-driven conveyors 14, each equipped with a number of projecting elements that define separate compartments 14a.
  • the compartments 14a of the feed device defined by the chain-driven conveyors 14 are to be fed each with a single bar by means of the automatic loading device that will be described in detail in what follows.
  • the conveyor system constituted by the array of chain-driven conveyors 14 is also illustrated schematically.
  • the reference number 50 designates a device for automatic picking-up and loading of any predetermined and desired number of metal bars onto the conveyor system constituted by the chain-driven conveyors 14.
  • the device 50 picks up the bars from a bundle of bars B prearranged in a magazine of bars M, which, in the example illustrated, is constituted by a channel-like structure 51 supported by a framework 52 and provided along its bottom with an array of horizontal rollers 53 mounted in a freely rotatable way, which favour feed of the bars B above the magazine M.
  • the device 50 comprises a fixed supporting structure, which, in the example illustrated, has two end heads 54, which each include a base 55 resting on the floor, a column 56 extending upwards from the base 55, and a cross member set in cantilever fashion 57 projecting from the top of the column 56 in a transverse direction with respect to the longitudinal direction of the magazine M.
  • two carriage structures 58 are guided, each having at least one motor-driven roller or wheel 59.
  • the two motor-driven wheels 59 are driven between respective mutually aligned shafts 60 extending in a direction parallel to the longitudinal direction L of the magazine M.
  • the two shafts 60 extend from a motor reducer 61, which connects the shafts themselves to an electric driving motor 62, for governing simultaneous displacement of the carriages 58 along the cross member 57 in a direction transverse with respect to the longitudinal direction of the bars B, said transverse direction being designated by the arrows X in the drawings.
  • Any different system of transmission is of course possible; for example, two motors associated, respectively, to the two carriages could be envisaged.
  • each lever 64 mounted articulated on the beam 63 about a common longitudinal axis 64b and governed each by a respective fluid actuator 65 between an inoperative position (visible in Figure 3 ), in which the free ends of the levers 64 face vertically downwards, and an operative position (visible, for example, in Figure 10 ), in which the free ends of the levers 64 extend horizontally in cantilever fashion starting from the beam 63.
  • the free end of each lever 64 carries a freely rotatable roller 64a designed to favour proper engagement of the bars B above the levers 64 when the latter are in the operative position, as will emerge more clearly from the ensuing description.
  • the beam 63 also carries an endless chain C, which engages on two gears 66 set at the ends of the beam 63 and has two longitudinal branches extending parallel to the longitudinal direction L of the magazine M.
  • One of the two gears 66 is governed by an electric motor (not visible in the drawings), which enables motion to be imparted on the endless chain C.
  • Said chain is used for governing a displacement in the longitudinal direction (designated by the arrows L in the drawings) of the magazine M of a further lever device (see, for example, Figure 9 ) comprising a lever 68 mounted articulated about a vertical axis on a plate-type support 67 connected to the chain C and governed by means of a fluid actuator 69 between an inoperative position, in which it extends parallel to the original direction L (see, for example, Figure 3 ), and an operative position, visible in Figure 9 , in which it extends in the transverse direction X.
  • the lever 68 carries a freely rotatable roller for proper engagement thereon of the bars B, as will be illustrated in greater detail in what follows.
  • a device for picking up the bars comprising a magnet 70 set at the bottom end of a vertical stem governed by a fluid actuator 71.
  • a limiter device 72 illustrated schematically in Figure 13 .
  • Said device is basically constituted by a pair of plates 73 extending in a common plane orthogonal to the longitudinal direction L, said plates being connected rigidly, in the specific case illustrated herein, to the structure of the respective carriage 58.
  • the two plates 73 define between them a vertical passage 74 of a width corresponding to the thickness of the bars B (preferably envisaged is the possibility of regulation of the distance of the plates 73 in order to adjust the width of the passage 74).
  • the passage 74 moreover has a V-shaped lead-in mouth 75.
  • the limiter device 72 basically functions as limiter designed to enable only the end of one bar at a time to reach the raised position above the limiter 72. Even though it is not illustrated in the annexed drawings, it is also possible to envisage a gripper device that blocks temporarily in position the portions of bar that reach the aforesaid raised position.
  • the pre-arrangement of the carriages 58 enables the magnet 70 for picking up the bars to be brought onto the vertical of the area of the magazine M, where the bars are to be picked up. Said characteristic is important in so far as it always enables bars to be picked up from the magazine M even when the latter is progressively emptying.
  • said magazine is defined by mobile walls, which are able to keep the bars B of the bundle always in a grouped position suitable for facilitating picking-up of the bars set on the top of the bundle, for example, causing the bundle always to have a greater height in the central area (with respect to the transverse dimension of the bundle).
  • the magazine can be defined by a structure with fixed walls, shaped, however, in such a way as to provide a cradle effect, to keep the bars grouped together as the magazine empties.
  • Figure 3 shows the carriages 58 in the inoperative position, at the end set further back of the cross member 57.
  • the carriages 58 are brought into an advanced position, where the magnet 70 is on the vertical of the bars B set in the magazine M.
  • the magnet 70 is lowered ( Figure 5 ) and then raised again so that the end of one or more bars B can be picked up.
  • said bars are forced to pass through the limiter 72 ( Figure 13 ) so that just one bar remains attached to the magnet 70 and reaches the raised position visible in Figure 7 .
  • the lever 68 is brought into its operative position by means of activation of the actuator 69 (more clearly visible in Figure 9 ), so that the lever 68 moves underneath the raised end of the bar that has been picked up, as illustrated in Figure 7 .
  • the endless chain C is set in motion so as to displace the lever 68 longitudinally in the direction L and raise the bar B that has been picked up progressively throughout its length.
  • the lever 68 proceeds from one end to the other of the bar B that has been picked up, the raised part of the bar is kept in said position by gradual activation of the levers 64.
  • Figure 8 shows the device with the lever 68 that has already been displaced for a certain length underneath the bar B that has been picked up, so that one of the levers 64 (the one furthest to the right in the figure) has been brought into the operative position, so as to support the bar B.
  • Figure 9 shows the further displacement of the lever 68, with the consequent raising of the levers 64 set to the right thereof (with reference to the figure), and
  • Figure 10 shows the end of said operation, with the lever device 68 that has reached the opposite end of the beam 63 and all the levers 64 set in their raised operative position, where they keep the bar B that has been picked up in the raised position.
  • the bar that has been picked up and completely separated from the bundle can then be laid in a corresponding compartment 14a of the feed system defined by the chain-driven elevators 14 by means of advance of the carriages 58 and partial rotation of the levers 64, as illustrated in Figure 12 .
  • the bar B is displaced upwards by the chain-driven device 14 ( Figure 2 ).
  • the operation is repeated in succession for a plurality of bars so that all the compartments 14a are filled with a respective bar B, as illustrated in Figure 2 , which enables the bars B to be fed in rapid succession onto the sliding surface Q, from which the bars drop once again in rapid succession, so as to reach in times that are close to one another but distinct the receiving space 8 on the bending units, which guarantees that said bars cannot bestraddle one another in said final step of conveyance into the receiving space 8.
  • the fundamental characteristic of the device for picking up and loading automatically the bars lies in the fact that the operations of picking up, separating, and transferring the bars B from the magazine M up to the operating unit are performed by displacing the bars only in a transverse direction with respect to their longitudinal direction, i.e., without any substantial movement of the bars in their longitudinal direction.
  • the device for automatic picking-up and loading of the bars has been described with reference to feeding of the bars to a system for bending bars.
  • the device could, however, be used for feeding the bars to any operating unit, for example, also to a bench for cutting bars or any other workstation of a system.
  • the example illustrated herein presents the further characteristic of picking up, separating, and transferring only one bar at a time. Said characteristic guarantees proper picking-up and loading of the bars.
  • the relative movement in the direction X between the pick-up device 70 and the separating means 68, 64 on the one hand, and the bars in the magazine M on the other can be obtained in a different way, for example, by providing a magazine that is mobile in the direction X.
  • the conformation and arrangement of the separator member 68 and of the supporting member 64 can of course also be varied as compared to the one illustrated herein purely by way of example.
  • actuator means of a different type for governing longitudinal movement of the separator member 68 and the movement of activation of the supporting member 64 can be devised in a way different from what has been described herein purely by way of example.
  • Picking-up of the bars can be performed by gripping the bars at one end or at the centre, or in any other intermediate position.
  • the separating members can consequently be one or more and can be displaced longitudinally or else be situated in fixed positions in the longitudinal direction and be activated in succession to engage different portions of the bar.
  • FIGS 14-22 illustrate a second embodiment of the device for automatic picking-up and loading of bars described herein.
  • the elements in common with the embodiment previously illustrated are designated by the same reference numbers.
  • Said embodiment differs from the one previously illustrated in that in it the pick-up device 70 is set on the beam 63 in such a way as to grip one or more bars in their central portion.
  • the pick-up device is set at the centre of the beam 63, together with the limiter device (not illustrated) described previously with reference to Figure 13 .
  • the pick-up device 70 has - also in this embodiment - a magnet, but it is clear that, as an alternative, it could also have gripper means or any other pick-up means capable of taking the portion of one or more bars from the bundle of bars in the magazine up to a position at a distance from the bundle of bars.
  • the means for separating the bars comprise, instead of the single chain C that extends from one end to the other of the beam 63, two endless chains C', each carried by a pair of gears 66 mounted on the beam 63.
  • the two chains C' are set on either side of the pick-up device 70 so as to extend each along one half of the beam 63, from an area in the proximity of the device 70 as far as the end of the corresponding beam.
  • Each chain C' carries with it one or more rollers 68' freely rotatable about their own axis and extending in the direction X. As will be seen in what follows, the rollers 68' perform the function of engaging the bars picked up to raise them progressively along their length and thus separate them from the bundle of bars in the magazine.
  • the beam 63 carries a plate 81 designed to define a contrast surface for the bars that have been picked up.
  • the carriages 58 are brought as far as the advanced position illustrated in Figure 15 , where the magnet 70 is on the vertical of the bars B set in the magazine M.
  • the magnet 70 is lowered ( Figure 16 ) and then raised again so as to pick up the central portion of one or more bars B.
  • said bars are forced to pass through the limiter device illustrated in Figure 13 so that just one bar remains attached to the magnet 70 and reaches the raised position visible in Figure 17 .
  • the chains C' start to move along their respective closed path: the chain C' illustrated on the left in the figures in a clockwise direction, and the chain C' illustrated on the right in the figures in a counterclockwise direction.
  • the rollers 68' move underneath the central raised portion of the bar that has been picked up, as illustrated in Figure 17 , and, starting from said condition, move longitudinally in the direction L, the rollers 68' of the left-hand chain C' towards the left, and the rollers 68' of the right-hand chain C' towards the right, so as to raise progressively the opposite portions of the bar B that has been picked up.
  • Figures 19 and 20 show picking-up of a second bar B' within the same step of loading by the device, immediately after the first bar B has been picked up and separated from the bundle of bars in the magazine.
  • the magnet 70 picks up the central portion of the bar B'.
  • the rollers 68' are moved in the direction L, as described above, and come to engage said bar for raising it progressively.
  • the levers 64 are lowered in succession and then raised again to prevent interference with the action of the rollers 68': in particular, each lever 64 moves downwards when the roller 68' directed towards it is still at a given distance, whilst it rises again only after the roller 68' has passed beyond it so as to support both the first bar and the second bar.
  • the distance referred to above between the lever 64 and the roller 68, at which it is envisaged that the lever 64 will move down, must be such that, in the first place, the bar B' that the roller 68' itself is raising, does not interfere with the lever 64 itself, while this is moving down, and, in the second place, the portion of the bar B that up to that moment was supported by the lever 64 comes temporarily to rest on the roller 68' itself until the lever is raised again. This occurs for all the levers 64 until both the first bar and the second bar again find themselves supported by said levers, which are all again in their raised position.
  • the bars B, B' and B'' picked up and completely separated from the bundle, can then be set in a corresponding compartment 14a of the feed system defined by the chain-driven elevators 14.
  • the device for automatic picking-up and loading illustrated in Figures 3 to 12 is able to pick up and load a plurality of bars at a time on the transfer means 14.
  • the levers 64 are lowered and then raised again in succession, in order not to interfere with the action of said member.
  • the structure of the device for automatic picking-up and loading of the bars described herein could be provided alongside the cutting bench, and the feed device with chain-driven elevators 14 could cause the bars to drop on the bench, where they would subsequently be referenced in position and cut to the desired length.
  • the device could be set alongside a bench aligned longitudinally with respect to the cutting bench, where the bars picked up can be again grouped and then fed longitudinally to the cutting bench, where they could be cut all together.
  • the system is of course prearranged for being controlled automatically by means of an electronic control unit, according to a technique in itself known, which activates the various component parts of the system in an automatic way, according to any predetermined cycle and on the basis of the setting of the desired number of bars to be fed to the operating unit.
  • the device gets the portion of just one bar at a time to arrive in the raised position above the magazine and consequently envisages separation of just one bar at a time from the bundle and transfer of just one bar at a time to the operating unit.
  • handling of just one bar at a time could be left just to any one of said operations.
  • the final transfer step could be performed simultaneously for a number of bars together, without prejudice to the principle of displacement of the bars only in the longitudinal direction.
