Definitions

  • the present invention refers to a method for controlling the operating position of a grinding wheel used in a machine for machining edges of plates made of glass, marble and similar stony materials, and to a machine for implementing said method.
  • Bilateral grinding machines used for surface finishing of edges of a glass raw plate, previously cut by means of another device comprise a grinding area defined between at least two rows of opposite diamond and polishing wheels, at least the first being designed to simultaneously remove material from those opposite edges of the plate; the various driving spindles of the wheels of each row are associated with respective shoulders of the machine, one being stationary and the other movable; the possibility to shift the movable shoulder with respect to the stationary one enables to use the machine for machining plates with different widths.
  • the glass raw plate is guided in a first direction, so as to pass across the grinding machine in which material is removed from a first pair of opposite edges of the plate; in some cases said plate is then guided in a second direction, orthogonal to the first one, for machining its other two opposite edges in a following grinding machine, which is basically the same as the previous one.
  • said grinding wheel checking and repositioning step is carried out manually, which results in a high waste of time and long manufacturing idle times.
  • the size of plates getting out of the grinding area of the machine should be periodically checked; in case the width of the plate getting out is larger than the one set for machining purposes, one or more wheels should be repositioned, in order to recover their wear degree; this is basically carried out by changing the position of the concerned grinding wheel or wheels, conveniently mounted onto respective slides. Also such kind of measure usually results in long manufacturing stops.
  • the bilateral machine is equipped with a system for automatically detecting the wear degree of the diamond wheels and for repositioning the latter accordingly; to said purpose, the driving spindles of the wheels are provided with respective advancing means, so as to correct their position depending on the detected wear.
  • a solution of this type is known for instance from EP-A-1 063 053, which describes a bilateral machine having a dimensional detection system for the plate getting out of the grinding area, designed to control the movement of the advancing means of the last wheel of each shoulder.
  • the solution also envisages means for measuring the energy absorbed by motors driving some of the grinding wheels provided for: when the energy absorbed by the motor of a wheel increases, the wheel immediately upstream from the one undergoing check is advanced by the corresponding advancing means towards the edge of the glass plate.
  • the increase in the absorption of the motor of a grinding wheel is regarded as indicating that said wheel has more difficulty in removing material from the plate edge; said higher difficulty is due to the fact that the wheel immediately upstream from the one taken into consideration does not remove the correct amount of material because of its wear. Subsequently, the upstream wheel is advanced towards the plate edge.
  • the solution of the mentioned prior document is of "deductive" type and does not take into due consideration that the operating and dimensional properties of the grinding wheels to be used are not necessarily constant, i.e. the higher difficulty met by a wheel in removing material is not necessarily due to its wear. Moreover, the aforesaid known solution does not simplify the setting or change of the operating positions of the grinding wheels, which may be necessary for instance after replacing one of said wheels or because of machining changes in the grinding machine.
  • the main aim of the present invention is to carry out a new method enabling to control, set or change in a simple and accurate way the operating position of one or more grinding wheels, in order to obtain at the outlet of the grinding machine a plate whose size corresponds to the set size.
  • Another aim of the present invention is to carry out a new method, alternative to the "deductive" approach as in the prior art, for automatically correcting the grinding line, so as to compensate the wear of one or more wheels.
  • a further aim of the invention is to carry out a bilateral grinding machine implementing the aforesaid operating method.
  • the object of the invention is a method for controlling an operating position of a grinding wheel used in a machine for machining edges of plates made of glass, marble and similar stony materials, having the features of the characterizing portion of claims 1.
  • the aims of the invention are also achieved by means of a process for correcting the operating position of a grinding wheel depending on its wear and tear, in a machine for machining edges of plates made of glass, marble and similar stony materials having the characteristics of claim 11, and by means of a bilateral machine for machining edges of plates made of glass, marble and similar stony materials having the characteristics of claim 12.
  • Figure 1 globally refers to a line for machining the edges of glass plates, comprising two bilateral grinding machines, referred to with 2 and 3; between said machines 2 and 3 it is provided for a transfer apparatus or squaring device 4, which shall not be described because it is known per se, which is designed to lead the plates out of the machine 2 to the inlet of the machine 3.
  • the machines 2 and 3 are similar to one another and, therefore, only the new elements of machine 2 shall be described and disclosed in further detail in the following.
  • the machine 2 comprises a supporting frame, with which a plate conveying system is associated; in the case shown by way of example, and as in the prior art, said advancing system comprises pairs of motorized belts 6, equipped with pressure elements or sliding blocks, which withdraw a plate being machined L and advance it in the direction indicated by arrows A. Still in accordance with the prior art the frame of the machine 2 comprises a movable shoulder 7 and a stationary shoulder 8. The stationary shoulder 8 is associated with
  • Similar grinding assemblies GM, GM1 and polishing assemblies GL are associated with the movable shoulder 7, in opposite position with respect to the corresponding assemblies of the stationary shoulder 8.
  • the movable shoulder 7 can be moved away or closer with respect to the stationary shoulder 8, with motorized means, depending on the width between the two opposite edges to be machined of the plates L.
  • the movable shoulder 7 is positioned with respect to the stationary shoulder 8 so that the total amount of glass to be removed (i.e. the difference between raw plate width and plate width to be obtained), which shall hereinafter be referred to as "machining allowance", is distributed on the two edges to be machined on a basically equal basis.
  • At least the assemblies GM having the diamond wheels 9 are mounted onto motorized slides, controlled by a control unit, schematically represented by block SC in Figure 1; the unit SC is equipped with a suitable programming and display device, referred to with DP.
  • FIG. 2 schematically shows a section view, by way of example, of a grinding assembly GM, comprising a diamond wheel 9 whose driving motor is mounted onto a corresponding slide.
  • GF refers to a guide, integral with the movable shoulder 7, onto which a slide 11 supporting an electric motor 12 is mounted; the movement generated by the shaft 12A of the motor 12 is transferred through a gear transmission system, known per se and globally referred to with 13, to a spindle 14 supporting a respective diamond wheel 9.
  • Number 15A refers to the shaft of a motor 15, which shaft is connected by means of a suitable clutch 15B to a threaded bar 16; on the latter a volute 17 can slide, which is mechanically connected to the slide 11; thus, by driving the shaft 15A, the slide 11 can slide on the guide GF in the direction indicated by arrow B, depending on the sense of rotation of the motor 15.
  • the controlled shift of the slide 11, in terms of space and speed, is managed by the control unit SC, which suitably controls the motor 15, beyond the motor 12, in per se known ways; to said purpose the assembly GM is equipped with means, not shown, for detecting the stroke end of the slide 11, for instance in form of cams and limit switches.
  • Each assembly GM is further associated with respective means for detecting the position of the slide 11 with respect to the guide GF, schematically represented in Figure 1 by the block referred to with SP; the detection means SP can be of any known type, but in the course of the present description let us assume by way of example that they are common encoders.
  • each shoulder 7, 8 is associated with striker or abutting means used for setting the operating position of the diamond wheels 9 and for correcting, if necessary, said position depending on the wear degree.
  • each shoulder 7, 8 is associated in a fixed way with a stiff vertical element, for instance made of iron rectified with a rust-proof treatment, referred to with 18 in Figures 1 and 2; the element 18, which is in such a position as not to interfere with the passage of the plates L, defines strike or abutment areas for respective wheels, as shall be evident below.
  • a stiff vertical element for instance made of iron rectified with a rust-proof treatment
  • the element 18 is mounted so that respective areas or abutments, referred to with 18A, extend above the sliding plane of the plate L, and so that their face 18B towards a respective wheel 9, 9', 9" extends in a fixed position with respect to machine zero line, referred to in Figures 3 and 4 with DI; the horizontal distance between the face 19B and the machine zero line DI is a fixed parameter, stored in the control unit SC.
  • the unit SC is equipped with a program for controlling an initial preset function for grinding tools, i.e. grinding wheels 9, 9', 9".
  • the aforesaid preset program can be started by an operator by means of the device DP, for instance when a new grinding wheel 9, 9' or 9" has been mounted onto the machine 2.
  • the control unit SC controls the advance of the concerned slide 11, by means of the advancing system shown in Figure 2, towards the center of the grinding area, at a pre-established low speed; said advance goes on until the machining surface 9A of the grinding wheel 9, 9', 9" ( Figures 2 and 3) gets in contact frontally with its respective abutment 18A, i.e. the surface 18B of the latter, the variation of the encoder dimension of the detection means SP thus ending its variation.
  • the end of variation for the encoder dimension indicates that the front surface of the grinding wheel 9, 9', 9" has reached the surface 18B of the abutment 18A; the control unit SC then orders the motor 15 of the slide 11 to be turned off (which slide had however already stopped, thanks to the presence of the clutch 15B) and stores in real time the stop dimension, hereinafter referred to as "stop dimension"; the stop dimension of the assembly GM shall obviously still be stored in the control unit SC also after the machine 2 is turned off.
  • the unit SC can lead the machining point of the grinding wheel 9, 9', 9" to a desired position with respect to machine zero line DI; this is achieved by driving the corresponding slide 11, starting from stop position (i.e. zero position), until the respective means SP detect a given dimension being reached by said slide, which dimension clearly corresponds to a given position of the machining point 9A of the grinding wheel 9.
  • Preset function can obviously be performed with any frequency by the operator, and thus not only after new diamond wheels have been mounted onto the machine 2, both simultaneously for all the grinding wheels 9, 9', 9" and selectively for each of them; in particular, said procedure is carried out whenever a new machining has to be set or the wear degree of the grinding wheels 9, 9', 9" has to be checked.
  • control unit SC For machining purposes, by means of the control unit SC, beyond setting common machining parameters, the advancing speed for the plates L and the desired removal dimension are set for each diamond wheel 9, 9', 9" as absolute values; the control unit SC can show on the display of the device DP of Figure 1 also percentage removal of each grinding wheel 9, 9', 9" for each shoulder 7, 8.
  • the operator in charge of the machine 2 will be helped in setting the various technological parameters by the use of working sequences stored in the control unit SC, which can be displayed on the device DP, grouped according to the different thickness of the plates to be machined and to the speeds used on the machine 2.
  • each encoder 20 can comprise a driving cylinder 20A having a stem 20B on whose end a contact idler wheel 20C is present, ground and concentric with respect to its rotation axis; the cylinder 20A is fastened to its respective shoulder 7, 8 and is equipped with means, known per se and interfaced with the unit SC, for detecting the relative position of the cylinder 20A with respect to its stem 20B.
  • the linear encoder 20 is not equipped with a limit switch; that is why, in order to store the dimension of said encoder with respect to line DI, an initial setting has to be made when installing the machine 2, consisting in activating the cylinder 20A until the stem 20B leads the idler gear 20C onto an abutment temporarily positioned on machine zero line DI. Now the measuring linear encoder 20 is reset and its respective dimension is stored in a variable within the control unit SC; the aforesaid setting abutment is removed from the machine.
  • the measure of the glass plate L being machined is required to be checked through a corresponding program which the control unit is equipped with.
  • Said measuring program activates both encoders 20; in particular the two stems 20B are let out of their respective cylinders until each idler wheel 20C rests on a corresponding edge of the movable glass plate getting out of the grinding area; the extension of the stem 20B generates the encoder dimension, which is then stored in the control unit SC.
  • the encoder dimensions of the two measuring units 20 are preferably summed up algebraically, so as to know the point-to-point difference, which, averaged out and summed to the width of the opening of the shoulder 8 with respect to the shoulder 7, defines the real dimension of the machined glass.
  • the size thus calculated for the plate L is compared with the theoretical size of the plate to be machined, set at the beginning on the control unit SC, and, but for a tolerance provided for in machine data, said unit SC checks whether the machined plate is acceptable in terms of size.
  • Said operations consist in stopping the device D guiding the plates on the machine 2, waiting for the removal of the plates that might be present in the machine, and carrying out the automatic correction of the motorized slides 11.
  • it is provided on the control unit SC for a suitable table in which intervention threshold retrieval parameters are stored, respectively for the last-but-one and the last diamond wheel of each shoulder, i.e. wheels 9' and 9" with reference to Figures 3 and 4, for side and for plate thickness.
  • the aforesaid parameters represent the maximum retrieval dimensions for each wheel 9', 9"; this means that if the error (i.e. the difference between theoretical plate and measured plate) is smaller than set tolerance, no compensation shall be carried out; conversely, if the error is between set tolerance and the retrieval parameter of the last wheel grinding 9", the control unit SC shall advance the slide 11 of the last grinding wheel 9" of an extent corresponding to error retrieval; however, if the error is between the two retrieval parameters of the last-but-one and last grinding wheel, the unit SC shall advance the last grinding wheel 9" of a extent corresponding to its retrieval parameter and the remaining difference shall be retrieved on the last-but-one wheel 9', by advancing it; eventually, if the error is larger than the retrieval parameter of the last-but-one wheel 9', the unit SC shall execute the preset function, as previously described, by means of the abutments 18A.
  • the control unit SC shall be advantageously provided with a mark table for each shoulder, defined depending on plate thickness.
  • the data to be set by means of the programming device DP shall be those concerning the size of the finished plate to be obtained, the size of the cut plate getting in and its thickness, as well as dimensions indicated by the mark table; as was said, the partial machining allowance referred to with S in Figures 3 and 4, i.e. half the difference between final machined glass and cut glass getting in, shall be equally distributed by the machine on both edges to be machined.
  • Figure 4 shows a partial machining allowance S of 1.4 mm, in which case the marks I1, I2 and I3 for the three grinding wheels 9, 9' and 9" of the series can be of 1 mm, 0.3 mm and 0.1 mm, respectively; at the outlet of the last wheel 9", the whole partial machining allowance S will be removed from the edge of the plate L, so that said edge has the desired dimension, as represented in Figures 3 and 4 by line DF.
  • the described system enables to set with accuracy the machining point 9A of the various grinding wheels, in a simple and automated way; moreover, the control unit SC can have a convenient check function in case one might want to give the user of the machine 2 the possibility of an "empirical" measuring of wheel marks, said measuring being merely optional.
  • the aforesaid check function envisages at first the performance of the preset function described above, which consists as was said in leading the concerned grinding wheel or wheels in contact with their respective abutment 18A, and in storing the corresponding encoder dimension. Then the slide or slides 11 are withdrawn by unit SC until the machining point of the grinding wheel or wheels is aligned with machine zero line D1, which represents the dimension for no removal at all.
  • the control unit SC shifts the motorized slides 11 until they reach the dimensions indicated in the removal table for each grinding wheel 9, 9', 9"; if there is a difference between partial machining allowance S and total removal in the table, the control unit SC shall drive the motorized assembly shifting the movable shoulder 7, which shall be shifted of exactly said difference.
  • the control unit SC activates the motors 12, thus driving the corresponding wheels, while a plate L is introduced into the grinding area; once all wheels have left their marks, though without completing the grinding of the whole edge of the plate L (as can be seen in the example of Figure 4), the advance of said plate is stopped; the motorized slides 11 are withdrawn up to a parking dimension and the plate L is removed from the grinding area, so that the various marks left can be checked empirically by the operator.
  • the motor 12 of each wheel can be associated with a digital ammeter, schematically referred to with 21 in Figure 2, used as control instrument by the unit SC for ensuring a correct technological use of said wheel, on the basis of control parameters stored in said unit.
  • the aforesaid parameters are used by the unit SC for controlling the optimal rotation speed of the grinding wheels 9, 9', 9" depending on the absorption of their respective motors 12 and on the variation of machining resistance due to the removal of irregular glass present on plate edge (the so-called "cutting shoe").
  • the system is also provided with an inverter for each pair of opposite assemblies GM, thanks to which the rotation speed of the respective motors 12 can be adjusted; in Figure 1 IN refers to the inverter of only one assembly GM.
  • a current absorption datum concerning the motor 12 and a given intervention threshold for avoiding the oscillation phenomenon are set on the control unit SC; if absorption tends to rise, the control unit SC drives a proportional, instantaneous increase in the number of revolutions of the motor 12, thus increasing tool removal capability; the speed increase will thus reduce the stress on the tool, and therefore amperage will sink, until rotation goes back to standard values.
  • wheel usage parameters in terms of absorption and rotation speed
  • the squaring unit 4 of Figure 1 directs said plate towards the machine 3, in per se known ways. This is then followed by the machining, on machine 3, of the two edges of the plate L orthogonal with respect to those that have been previously machined on machine 2.
  • the working of machine 3, as far as the features of the invention as described before are concerned, is the same as the one of machine 2; by the way, it should be pointed out that in case of lines as the one shown, one control unit SC can be provided for managing both units 2 and 3.
  • the plate dimensional reading means i.e. measuring encoders 20, can be used for performing an automatic retroactive adjustment control on the tool 9.
  • Said system provides that even only the slide 11 of the last assembly GM is motorized, i.e. the assembly having the wheel 9" of Figures 3 and 4.
  • automation consists in measuring the plate L at the outlet of the single machine 2, 3 by means of the sensors 20, and in case the computed difference between theoretical plate and measured plate is below the intervention threshold of the last grinding wheel 9", the control unit SC automatically adjusts the advance of the slide 11 of the latter, in order to make up for said error; the detected difference can alternatively be shown only on the display of the device DP.
  • FIG. 5 shows a grinding assembly GM comprising the guide GF and the corresponding slide 11, as well as the corresponding driving and motion transmission means 15, 15A, 15B.
  • the slide 11 is associated with a second vertical guide, referred to with GF', which is operatively associated with a respective slide 11', the latter supporting the motor 12 driving the grinding wheel 9, which is here a tangential mark wheel.
  • a volute 17' can slide, which is mechanically connected to the slide 11'; thus, by driving the shaft 15A', the slide 11' can slide vertically on the guide GF, in the direction indicated by arrow C, depending on the sense of rotation of the motor 15'; this is done in order to position the wheel 9 in the suitable point with respect to the edge of the plate L to be machined.
  • the grinding wheel 9 in order to perform preset function, the grinding wheel 9 will be first lifted by means of the advancing system GF', 11', 15', 15A', 16', 17' until the machining surface 9A is arranged parallel to the abutment or reference surface 18B. Then the wheel 9 will be advanced towards the element 18 by means of the advancing system GF, 11, 15, 15A, 16, 17 up to stop position; this will be followed by the withdrawal of the wheel 9 up to the necessary dimension and its lowering.
  • FIGs 6 and 7 show the working principle of grinding assemblies like the one shown in Figure 5, which, as can be inferred, is identical to the one previously described with reference to Figures 3 and 4.
  • the invention can obviously be carried out also in order to use the machine 2 or 3, as previously described, for machining only one edge of the plates L.
  • the described method also applies to the polishing assemblies GL, for checking and retrieving the wear of their grinding wheels 11, as well as to the corner finishing assemblies GM1, through a suitable positioning of the abutments 18A.
  • the element 18 has a globally embattled shape, so as to have abutments 18A separate one from the other, but said element could obviously have another shape, for instance as a simple vertical plane defining a continuous surface 18B.
  • the element 18 with the abutments 18A could also be vertically movable, so as to be selectively shifted between a rest position and a working position between the machine zero line D1 and the slides 11; thus, the assembly GM of Figure 2 would be able to correct the position of the respective grinding wheel also without removing plates that might be present in the machine, by carrying out the following cycle of operations:
