Definitions

  • the present invention relates to equipment for automatic production lines of electric motor armatures and more precisely it relates to a mobile work piece carrier, or pallet, having supports capable of holding armatures, which belong to a family of different sizes worked on such lines and of safely retaining them.
  • the invention relates to a method for carrying armatures to be worked on, on a pallet.
  • each pallet that is initially located in a station of inlet for receiving an armature, proceeds on a conveyor belt that causes it to move selectively through the workstations.
  • the armature is offered to a machine that draws it from the pallet, works it and returns it again on the pallet that proceeds on the conveyor.
  • the pallet continues to rest on the conveyor located underneath, for example a conveyor belt, in sliding contact on the belt same, or it can be raised or withdrawn from the conveyor belt, for example put in a waiting station.
  • the pallet is withdrawn or maintained on the conveyor belt because it can proceed up to a next workstation.
  • manually adjustable pallets exist, like those described in EP267324, that comprise fixed supports that can be adjusted and then blocked in a precise position for receiving the armature.
  • a manually adjustable pallet of traditional type requires that the supports are loosened, for example, by means of screw coupling, in order to move them to a position in which they are then locked to steadily support the armature.
  • the machines in the various stations of the line are of flexible type, i.e., they can be adapted quickly to operate with armatures of different size, also the pallet, therefore, must be adjusted in real time not much before receiving each armature.
  • pallets are known with automatically adjustable supports.
  • pallets of this type are described in EP348715, EP447805, and EP811463.
  • an adjustable pallet requires a station of automatic adjustment of the supports, or an operator that adjusts them manually.
  • variable dimensions in case of the armatures, are armature stack height, armature stack diameter, position of the armature stack and commutator on the shaft, shaft diameter, shaft length, shape of the shaft ends, etc.
  • a further drawback of the pallets of the prior art is that they provide systems for holding the armature at the free shaft ends. For some types of armatures, however, after winding, one of the shaft ends is substantially hidden by the coils of the wound wire, making it impossible to put both ends on the respective supports.
  • armatures having an axis and comprising a plurality of portions having axial symmetry, in particular a shaft and an armature stack of ferromagnetic sheets driven on said shaft, whose characteristic is that it has a base on which suitable support means are mounted for engaging with at least one of said portions having axial symmetry and for keeping the armatures with axis substantially horizontal preventing it from moving during its transportation.
  • the portion having axial symmetry engaging with the support means is the armature stack of sheets, the support means comprising:
  • the support means are two jaws movable with respect to each other between a first and a second position, in the first position the jaws approaching radially the armature stack for engaging with it, in the second position the jaws being distanced for having the armature loaded/unloaded during a working step.
  • the jaws are mounted movable transversally with respect to the armature axis biased by resilient means, and move from the first to the second position forced by a releasing means which can move in a direction substantially orthogonal to the base of the pallet and that engages with a conjugated surface associated to the jaws. Therefore, in the second position the jaws are influenced by the resilient returning force that biases their moving away from each other. This way, when the releasing means withdraws to a starting nominal position or, in the presence of the armature stack, to the first position where they are closed on the armature stack, the jaws have a residual resilient force sufficient to hold the armature.
  • the releasing means may have tapered side faces along which rollers connected to each jaw can slide.
  • the releasing means are advantageously integral to a gripper of means for picking up the armature from above or from below.
  • each jaw has one end shaped in order to form substantially a bevel that makes easier the introduction from above the armature stack on the support means and the other end hinged to a horizontal axis. This way the jaws can move rotationally with respect to each other rotating about the hinge between the first and second position.
  • the angular motion of each jaw is biased by a resilient force suitable for carrying the support means to close on the armature after having positioned the latter on the former.
  • the pallet thus arranged is capable of holding armatures with different stack diameters according to the resilient stroke between the first and the second position.
  • the means for bearing can comprise a fixed cradle, for example, formed by two rods that are arranged parallel to the armature shaft on which two generatrix lines of the armature stack rest.
  • the rods of the cradle can bear armatures with different armature stack diameter, since the armature stack rests on the rods along its own generatrix lines.
  • a third exemplary embodiment of the present invention provides fixed means for bearing arranged as a cradle for the armature stack and having at least one portion of its surface that faces the armature provided with a magnet, so that the portion of the armature stack located at the magnet is attracted thus blocking the whole armature.
  • a further exemplary embodiment of the present invention provides that on the cradle at the magnets a member is arranged suitable for pushing the armature against the cradle.
  • the member is a finger operatively connected to a resilient element by means of which it is possible to control, within predetermined values, the resilient force applied to the armature for assuring a steady clamping on the support means.
  • All the exemplary embodiments above indicated enable picking up the armature from the pallet either from above or from below.
  • the base has an opening to allow lifting means to pass.
  • An advantageous exemplary embodiment that can apply to all the previous embodiments provides that with respect to the pallet the support means enable receiving an armature both with a commutator oriented in a first direction and with a commutator oriented in a second direction, opposite to the first.
  • the support means are sized so that when the commutator is arranged in the first direction with respect to the pallet the armature belongs to a first dimensional class, whereas when the commutator is arranged in the second direction, the armature belongs to a second dimensional class, different from the first.
  • the support means in this case, have means for bearing the armature by the armature stack and means for holding the armature stack that are doubled.
  • the portion having axial symmetry engaged by the support means is the shaft of the armature, the support means comprising in this case a first and a second support capable of approaching and/or moving away from each other with respect to the armature axis at the moment of receiving and/or releasing a portion of the shaft.
  • the first and second support means are capable of approaching and/or moving away from each other in a substantially axial direction with respect to the armature axis.
  • the first and second support means are capable of approaching and/or moving away from each other in a substantially radial direction with respect to the armature axis.
  • first or the second support means move at the moment of receiving and/or releasing the armature axis whereas the second or first support means respectively remain still.
  • actuating means are provided, for example, of pneumatic type, suitable for causing the mutual approaching and/or moving away of the first and second support means.
  • At least one of the support means has an elongated portion movable in a substantially axial direction suitable for engaging with the corresponding portion of the shaft of the armature.
  • the elongated portion is capable of inserting in the space set between the coils and the armature shaft so that it can work also in the case of armatures having a portion of the shaft that is short and close to the armature stack of sheets.
  • the elongated portion of the support means can be connected to the actuating means with a releasable connection so that it can be replaced by one of different size.
  • the moving away stroke of the first and second support means is biased by resilient means.
  • the support means can have an end shaped in order to provide substantially a bevel that makes easier the location from above the armature on the pallet. This way, at the moment of positioning the armature on the pallet the support means are elastically forced to move away from each other to allow the armature to fit correctly. After positioning, the resilient means urge the armature, thus preventing it from moving during its transportation. At the moment of picking up the armature by gripping means at a workstation the embodiment above described allows in any case an easy maneuver. This way the pallet has substantially “self-adjusting” supports, i.e., capable of conforming and adapting automatically to the size of the transported armature shaft.
  • the support means can approach and/or move away from each other in a substantially radial direction with respect to the armature axis, they can be two jaws, preferably, having a substantially “V-shaped” surface suitable for receiving shafts of armatures of different size.
  • the exemplary embodiments above indicated enable picking up the armature from the pallet either from above or from below.
  • the base has an opening to allow lifting means to pass.
  • a method for handling electric motor armatures on automatic production lines using a pallet where the armatures comprise a plurality of portions having axial symmetry, in particular a shaft and an armature stack of ferromagnetic sheets driven on the shaft, provides that the armatures are carried on the pallet engaging at least one of the portions having axial symmetry and maintaining the armatures with axis substantially horizontal for preventing it from moving during its transportation.
  • the armatures are borne at the armature stack and at the same time held at the armature stack for preventing the armature from moving.
  • the armatures are carried on the pallet holding them at the shaft by support means capable of approaching and/or moving away from each other with respect to the armature axis same at the moment of receiving and/or releasing a portion thereof.
