Definitions

  • the present invention relates to machines for processing plates, for example plates of glass, plates of natural or synthetic stone material and slabs of wood or other materials suitable for the technology which is presented herein.
  • the invention relates to machines for processing plates, of the type comprising:
  • Machines of the above indicated type have been produced and marketed since long by the Applicant.
  • a machine according to the preamble of appended claim 1 is known from EP 2 719 501 .
  • a machine of this type is also known for example from EP 2 039 464 B1 .
  • These machines have been used originally for performing drilling operations on the plates. To this end, they usually have a processing station comprising a first and second machining heads movable along the above mentioned substantially vertical Y direction, and arranged on opposite sides with respect to the general plane of the plate.
  • the two machining heads have motorized spindles provided with drilling tools adapted to engage the plate from opposite sides, for performing a drilling operation trough the plate with no risk of damaging the plate.
  • Machines of the above indicated type have been also used for machining the peripheral surface of the plates in order to remove the cutting edge originated from previous cutting operations.
  • machines of this type have been further developed by providing automatic tool change on one or both the machining heads, in order to carry out different kinds of machining operations, such as grinding and polishing operations of the lateral surfaces of the plates, and, as indicated herein at the beginning, also milling operations, through which a portion of plate is removed in order to form an opening in the plate; the opening thus formed may be closed on its four sides, i.e. it may be entirely located inside the perimeter of the plate, or it may formed starting from a peripheral edge of the glass plate.
  • the machining waste material is typically let to fall down into a container provided at the bottom of the processing station.
  • this poses a limit to the size of the opening which can be formed by the milling operation because when the machining waste element has excessive dimensions it is not possible to let it fall down into the above mentioned container.
  • the technique is also adopted to interrupt the milling operation right before that the machining waste material becomes totally separated from the plate, so that an operator can remove the waste material by hand and subsequently start the plate machining process again.
  • the waste is divided in many portions, through smart programming of the strokes of the milling tool, thus ensuring that the portion which each time is removed from the plate always has dimensions sufficiently small to be able to fall into the waste container.
  • the object of the present invention is that of solving the above mentioned drawbacks, by proposing a new solution which can be advantageously used in machines of the above indicated type for removing the waste of the milling operations on the glass plates and which is not jeopardized by the limits which are proper of the known solutions.
  • the invention applies to a machine having the features which have been indicated at the beginning of the present description and further characterized in that said machine comprises at least one suction-cup gripping member, for gripping said plate portion constituting the processing waste, said suction-cup gripping member being adapted to be activated by depression and being displaceable from a retracted position to an advanced position along a direction parallel to said Z third direction, for engaging said plate portion constituting the processing waste that must be removed as a result of said milling operation, so as to hold said processing waste and prevent it from falling down after that the milling operation is completed.
  • the above mentioned gripping member is able to engage the processing waste, to remove it and then to hold it in a position spaced apart from the general plane of the plate, which does not interfere with the subsequent processing cycle of the plate. Therefore, with the invention, the processing waste materials originated from milling operations on the plate can be removed without involving any appreciable interruption in the processing cycle and with no limits to the dimensions of the processing waste materials.
  • the gripping member Once the gripping member has engaged and held a processing waste in a position spaced apart from the general plane of the glass plate, it is possible for an operator to pick up the waste material from the gripping member at the end of the processing cycle, or also during the processing cycle. It is not even excluded that the gripping member can be provided with an ability to move towards a position for automatic unloading of a previously taken processing waste.
  • said gripping member for gripping said plate portion constituting the processing waste is arranged at said processing station.
  • said gripping member provided at said processing station is movable along said second substantially vertical Y direction and said electronic means are programmed for carry out said milling operation so that in a last step of the machining operation the milling tool moves with respect to the plate only along said Y direction, so that during this last step the glass portion which must be removed can be held by said gripping member, since the plate does not move along the first direction X.
  • said gripping member for gripping said plate portion constituting the processing waste can be mounted at said processing station so as to be movable along said second substantially vertical Y direction independently with respect to said second machining head.
  • the gripping member can be supported by said second machining head so that it is movable along said second Y direction together with said machining head.
  • the above mentioned gripping member is constituted by a suction-cup unit selected among the suction-cup units forming part of at least one suction-cup carrying carriage.
  • the electronic control means of the machine are programmed to position said suction-cup carrying carriage with respect to the plate in such a way that said at least one selected suction-cup unit is engageable on said plate portion that must be removed as a result of said milling operation, keeping the at least one selected suction-cup unit completely within the perimeter of said plate portion.
  • a solution is also foreseen in which one or more dedicated gripping members are provided on a dedicated suction-cup carriage, which is independent with respect to suction-cup carriages which are used for moving the glass plate.
  • the invention also provides a processing method which can be carried out by the machine according to the invention.
  • the machine according to the invention is generally designated in the drawings by reference numeral 1.
  • the drawings show the case of a machining operation carried out on a glass plate, while it must be understood that the machine can be used in general on plates of any type of material which is adapted to the technology discussed herein.
  • the machine 1 comprises a fixed supporting structure 2 defining a processing line extending in a longitudinal direction X, along which the plates to be processed are caused to advance while being held in a substantially vertical plane.
  • the machine comprises two longitudinal arrays of motorized rollers 3,4 (a view at an enlarged scale of a rollers 3 is visible in figure 5 ) extending along the longitudinal direction X, upstream and downstream of a central processing station W.
  • the plates to be processed come from the left end (with reference to the drawings) of the machine and are supported at their lower edge on the line of rollers 3. As indicated, the plates are slightly inclined with respect to the vertical plane, so that with their rear face (i.e.
  • a similar frame 6 with wheels R for supporting the rear face of the machined plates, is arranged downstream of the processing station W (with reference to the direction of movement X of the plates).
  • conveying belts or automated movable clamp members can be used as a device for conveying the plate in the X direction.
  • the movement of the plate L in the X direction is further obtained by means of a plurality of suction-cup carriages C, provided with gripping members S which can be activated by depression and are movable from a retracted position to an advanced position for engaging the rear face of the plate L (that is the face opposite to that facing the viewer in the figures).
  • suction-cup carrying carriages is provided in the examples described herein, but does not represent an essential feature of the present invention.
  • the conveying device which is used for advancing the plates along the direction Zx may simply comprise the above described motorized rollers and/or alternative devices, such as conveying belts and automated movable clamp members.
  • each carriage C is independently slidably mounted on a longitudinal guide (not shown in the drawings) of the bottom fixed structure 2, so that it is movable in the X direction independently from the other suction-cup carrying carriages.
  • each carriage C is provided with motor means which drive its movement in the X direction, such as a motorized pinion in engagement with a rack. Also these details of construction are not illustrated herein, since they are known and do not fall within the scope of the invention.
  • suction-cup gripping members S the means for driving the movement of these suction-cup gripping members in a direction orthogonal to the glass plate, between a retracted position and an advanced position, and the means for communicating a depression to the suction-cup members are not illustrated herein, since they are known per se.
  • the general plane of the glass plate L is defined by the suction-cup members S of the suction-cup carrying carriages C.
  • the precise position of the plate L along the X direction is also defined by carriages C, whose motor means are controlled in synchronism by an electronic control unit E associated to the machine ( figure 1 ).
  • the machining station W comprises a fixed column structure 7 on which two machining heads H1, H2 are mounted so as to be movable parallel to a substantially vertical direction Y, these machining heads each carrying a motorized spindle having an axis parallel to a third Z direction ( figure 1 ) orthogonal to directions X and Y.
  • the spindle of each head can be coupled selectively with a machining tool (such as a grinding tool or a drilling tool, or a milling tool, or also a combined tool).
  • a tool magazine carried by a rack which is movable horizontally along the direction X with respect to structure 7 to enable an automatic change of the tool carried by each machining head (H1, H2), according to a technique known per se.
  • H1, H2 machining head
  • the two heads H1, H2 are provided on opposite sides with respect to the general plane of the plate to be machined, so that for example when on the spindles of the heads H1, H2 drilling tools are mounted, they can engage the plate L coaxially from opposite sides in order to properly carry out the drilling operation, according to a technique known per se.
  • the machining operations of the longitudinal edges (parallel to X) of the plate can be carried out by a movement of the carriages C along X, with simultaneous control of the position along Y of heads H1, H2 (which carry out simultaneously the grinding of the upper and lower edges of the plate).
  • the machining of the vertical edges of the plate is carried out by stopping the carriages C and moving one of the heads H1, H2 along Y.
  • on the spindles of heads H1, H2 grinding tools are mounted.
  • the movement of the machining heads H1, H2 in the Y direction, and the movement of the suction-cup carrying carriages C in the X direction are controlled by the electronic control unit E, according to any predetermined program.
  • the machine according to the invention is also used for carry out milling operations of the glass plate in order to form openings in the glass plate, of the type which is diagrammatically shown in figures 3A and 3G .
  • the two machining heads H1, H2 are used.
  • the machining head H1 which is located on the front part of the machine (with reference to figure 1 ) and which for this reason is also called the front machining head, so as to distinguish it from the machining head H2, which is called the rear machining head.
  • Figure 3A shows the case in which plate L has been subjected to a meaning operation in order to form an opening A therein which is closed on four sides, since it is entirely contained within the peripheral perimeter of the plate L.
  • the plate L is moved along the X direction by the suction-cup carrying carriages C until it is positioned with respect to the vertical axis Y of movement of heads H1, H2 at the position shown in figure 3B .
  • the plate is subjected to a first drilling operation by which a hole F is obtained which is required for enabling subsequent engagement through the plate of a drilling tool.
  • the motorized spindle of head H1 is provided with a milling tool U of the type visible at an enlarged scale in figure 4 .
  • the rotation of the milling tool U around its axis is then started while maintaining the front head H1 at a fixed position with respect to the vertical axis Y and simultaneously moving the glass plate L in the X direction, until forming the first side A of opening A1, as shown in figure 3C .
  • FIG. 4 of the annexed drawings shows an important component of the machine according to the invention, according to a first embodiment.
  • This figure shows the glass plate L at the end of a milling operation by which an opening A1 has been formed which is closed on four sides.
  • Figure 4 also shows the plate portion P constituting the machining waste which is held in a position spaced apart from the general plane of the glass plate L by a suction-cup gripping member V comprising a suction-cup which can be activated by depression and which is carried by an associated support so as to be movable between a retracted position (shown in figure 4 ) and an advanced position, in a direction substantially orthogonal to the plane of the plate.

  • the suction-cup gripping member V is moved to its advanced position and is activated by vacuum for engaging the rear face (with reference to figure 4 ) of the plate portion P, before that the milling operation shown in figures 3A-3F is terminated, so as to hold the plate portion P and avoid that it falls when the milling operation is terminated.
  • the suction-cup member V is brought back to its retracted position so that it removes the machining waste P and holds it at a position spaced from the general plane of the glass plate L, as shown in figure 4 .
  • the machining waste P is therefore removed in a completely automated manner, thus enabling at the same time the machining cycle to be immediately continued once the meaning operation is terminated.
  • the machining waste P is in the position spaced from the plane of the plate which is shown in figure 4 , where it is held by the suction-cup gripping member V, it is then possible to attend to removal of the machine waste without interfering with the machining cycle of the plate.
  • the plate portion P can be removed manually by an operator, or it can be provided that the gripping member V is brought to a position adjacent to a station for unloading the machining waste, where the waste can be automatically unloaded.
  • the solution shown by way of example in figure 4 is particularly simple to provide, since the suction-cup member V is carried by the structure of the rear machining head H2, whereby the movement of the suction-cup member V along the vertical direction Y is obtained by the same means which are provided for the rear machining head H2.
  • a suction-cup gripping member V constituting a separate unit with respect to the rear machining head H2 and movable along the Y direction on the same guides D2 of the rear machining head H2 or also on independent guides.
  • suction-cup gripping member V which can be moved both in the X direction and in the Y direction with respect to the structure of the machining station W, for obtaining maximum flexibility of operation.
  • the suction-cup gripping member V can also be provided with more than one suction-cup V, or also more suction-cup members V can be provided which are movable independently from each other.
  • the suction-cup for holding the waste is carried by a conical coupling element which can be coupled directly with the spindle of one of the two heads H1, H2.
  • the vacuum pump of the main circuit of the machine can be used, by providing a solenoid valve for controlling supply of vacuum to the suction-cup.
  • the system can be provided with a small pump on board the head which is able of generating vacuum by compressed air, due to the Venturi principle.
  • the suction-cup gripping member V is able of moving along the direction Y, but is not able to move along the X direction. Therefore, when the suction-cup gripping member V has gripped the plate portion P, before that the milling operation is terminated, is absolutely necessary that the remaining part of the milling operation does not imply a movement of the plate in the X direction. For this reason, with reference to figures 3A-3F , the machining cycle is carried out so that the last step of the operation involves forming a vertical portion of the opening perimeter.
  • the opening to be formed in the glass plate L is an opening A2 extending starting from a peripheral edge of the glass plate ( figure 3G )

  • One of the suction-cups S is shown in its retracted position, with the machining waste P carried thereby and held in a plane spaced apart from the plane of the glass plate L, after in milling operation by which an opening A in the glass plate has been formed.
  • suction-cup carrying carriage C has one of its suction-cups S which can be contained completely inside a perimeter of the opening A1 which must be formed in the glass plate.
  • a suction-cup carrying carriage dedicated solely to the above mentioned function, with a plurality of suction-cups of relatively small dimensions, which can be activated, singularly or in groups, for engaging the waste material whatever is its dimension and whatever is its position with respect to the glass plate.
  • a suction-cup carrying carriage of this type which is movable along the horizontal direction X and provided with one or more suction-cup members S which can be moved in the Y direction with respect to the carriage structure.
  • each suction-cup unit S can pivot with respect to a pivot axis in order to find the more proper orientation in order to be contained inside the machining waste.

    wobei die Bearbeitungsstation (W) mindestens einen ersten Plattenbearbeitungskopf (H1) zum Bearbeiten der Platte (L) umfasst, wobei der Kopf auf einer Seite bezüglich der Hauptebene der Platte (L) angeordnet ist, wobei der Bearbeitungskopf (H1) entlang einer zweiten im Wesentlichen vertikalen Y-Richtung beweglich ist und eine motorisierte Spindel mit einer Achse aufweist, die entsprechend einer dritten Z-Richtung orthogonal zu der ersten und zweiten Richtung X, Y ausgerichtet ist, wobei die Spindel dazu eingerichtet ist, mit mindestens einem Fräswerkzeug verbunden zu werden, das zum Fräsen der Platte (L) entlang einem vorgegebenen Pfad verwendet werden kann, um eine Öffnung (A1, A2) in der Platte zu bilden, wobei die Öffnung einen umfänglichen Rand der Platte (L) beabstandet oder sich von einem umfänglichen Rand der Platte (L) erstreckt, was zu der Entfernung eines Teils der Platte (P) führt, so dass Verarbeitungsabfall entsteht, und
    wobei das Verfahren dadurch gekennzeichnet ist, dass mindestens ein Saugnapf-Greifelement (V, S) zum Greifen des Plattenabschnitts (P), der den Verarbeitungsabfall darstellt, vorgesehen ist, wobei das Saugnapf-Greifelement dazu eingerichtet ist, durch Herunterdrücken aktiviert zu werden, und aus einer eingefahrenen Position auf eine ausgefahrene Position entlang einer Richtung parallel zu der dritten Z-Richtung verschiebbar ist, und dadurch, dass das Greifelement (V, S) auf seine ausgefahrene Position gebracht wird und durch Herunterdrücken aktiviert wird, um mit dem Plattenabschnitt (P) in Eingriff zu kommen, der den Verarbeitungsabfall darstellt und der als Folge des Fräsvorgangs entfernt werden muss, um den Verarbeitungsabfall (P) zu halten und zu verhindern, dass er nach Abschluss des Fräsvorgangs herabfällt, wobei das Greifelement (V, S) zurück auf seine eingefahrene Position verschoben wird, um den Verarbeitungsabfall (P) zu entfernen und in einer Position mit Abstand zu der Hauptebene der Platte (L) zu halten, nachdem der Fräsvorgang beendet ist.
  11. Verfahren nach Anspruch 10, dadurch gekennzeichnet, dass das Saugnapf-Greifelement (V) an der Bearbeitungsstation (W) angeordnet ist und entlang der zweiten im Wesentlichen vertikalen Y-Richtung verschiebbar ist, und dadurch, dass der Fräsvorgang so durchgeführt wird, dass sich ein Fräswerkzeug in der letzten Bearbeitungsphase relativ zu der Platte nur entlang der Y-Richtung bewegt, so dass während dieser letzten Phase der Plattenabschnitt (P), der entfernt werden muss, von dem Greifelement (S) gehalten werden kann, da die Platte in der ersten Richtung X nicht bewegt wird.
  12. Verfahren nach Anspruch 10, dadurch gekennzeichnet, dass mindestens ein Saugnapf-Tragschlitten (C) vorgesehen ist, der in der ersten Richtung X beweglich ist und eine Vielzahl von Saugnapfeinheiten (S) trägt, die dazu eingerichtet sind, durch Herunterdrücken aktiviert zu werden, und die mit der Platte in Eingriff gebracht werden können, um die Platte (L) zu halten und/oder entlang der ersten Richtung X zu bewegen, während sie an der Bearbeitungsstation (W) bearbeitet wird, während gleichzeitig eine Auflageebene für die Platte (L) präzise definiert wird,
    dadurch, dass das Saugnapf-Greifelement zum Greifen des Plattenabschnitts (P), der den Verarbeitungsabfall darstellt, von der mindestens einen Saugnapfeinheit (S) gebildet wird, die aus den Saugnapfeinheiten (S) ausgewählt wird, welche einen Teil des mindestens einen Saugnapf-Tragschlittens (C) bilden, der in der ersten Richtung X verschiebbar ist, und dadurch, dass der Saugnapf-Tragschlitten (C) bezüglich der Platte (L) so positioniert wird, dass die mindestens eine ausgewählte Saugnapfeinheit (S) mit dem Plattenabschnitt (P) in Eingriff gebracht wird, die infolge des Fräsvorgangs entfernt werden muss, wobei die mindestens eine ausgewählte Saugnapfeinheit (S) vollständig innerhalb des Umfangs des Plattenabschnitts (P) gehalten wird.
