Description

  The present invention relates to a glass separating apparatus for separating and removing glass for recycling glass used in devices such as solar cell modules, liquid crystal televisions, plasma televisions, etc., and in particular, a plate removed from these devices Glass separation apparatus for separating and taking out the glass from a treated product in which a sheet containing a resin is attached to the glass.

  Generally, for example, in a solar cell module, a sheet containing a resin is attached to a plate-like glass, and the sheet is surrounded by a metal frame. The sheet is mainly made of a resin protective material on which a solar cell element is formed and a filler for bonding the resin to glass. Moreover, the terminal box for electric power and the cable for wiring are attached to the back of the protective material. And although the solar cell module which became useless by end of life etc. is discarded, recycling is also performed in recent years. In this case, the terminal box and the cable for wiring are removed, the frame is removed, and the required members are recycled. In addition, from the sheet in which the sheet containing the resin is attached to the plate-like glass, the glass is separated and recycled, and the residue is melted and the required metal and the like are taken out and recycled.

By the way, it is not easy to separate the glass from the sheet in which the sheet containing the resin is attached to the plate-like glass, since the sheet is adhered by the filler, and an apparatus capable of easily processing this has been developed. . Conventionally, as a glass separation apparatus of this type, for example, one disclosed in Japanese Patent Application Laid-Open No. 2011-173099 (Patent Document 1) is known.
In this conventional glass separation apparatus, as shown in FIG. 12, the processing object W in which the sheet S is attached to the plate-like glass G is transported by the conveyor 100, and in this transport process Between the provided top roller 101 and the bottom roller 102 having a flat outer peripheral surface, the material is crushed (crushing process in FIG. 12A), and then a heater 103 is placed on the processed material W to soften the filler. After that, the fragments of the glass G (referred to as glass pieces Ga) are scraped off the sheet S by the blade edge of the blade 104 (separation step of FIG. 12 (c)).

JP, 2011-173099, A

However, in the above conventional glass separation apparatus,
(1) Since heating is performed by the heater 103 to soften the filler, it takes time to soften the filler until it is easy to separate.
(2) Since the softening process by the heater 103 is provided, the processing efficiency is bad because the number of processes increases accordingly.
(3) In addition, since the heater 103 is provided, the size of the apparatus is increased accordingly, which increases the cost.
(4) Furthermore, the viscosity of the filler is increased by heating and warming, and the filler tends to adhere to the glass piece Ga, and the separability is impaired.
(5) Further, in the crushing step, the workpiece W is crushed by being sandwiched between the top roller 101 provided with crushing tooth groups and the bottom roller 102 whose outer peripheral surface is flat, but the outer peripheral surface of the bottom roller 102 Is flat, cracks in glass G become insufficient and it is difficult to fragment.
There was a problem of

  The present invention has been made in view of the above problems, and it is possible to easily separate glass from a sheet without providing a softening step, to speed up separation, and to improve separation efficiency. The purpose is to provide a separation device.

  In order to achieve such an object, the glass separation apparatus according to the present invention holds and rotates the processed material in a glass separation apparatus that separates glass from a processed material in which a sheet containing a resin is attached to a plate-like glass. And a pair of crushing rollers for conveying the treated material and crushing the glass of the treated material, and scraping off the glass pieces of the glass provided on the downstream side of the respective crushing rollers and adhering to the sheet of the treated material A roller, a pressing roller for pressing the processed material against the scraping roller, and a feed conveyor provided on the upstream side of each crushing roller and supporting the glass surface between the crushing rollers and supporting the glass surface , And the feed conveyor can be adjusted so that the angle formed by the bearing surface for supporting the glass surface of the object to be processed is non-perpendicular to the plane passing through the axial center of the pair of crushing rollers. It has a configuration which is provided to.

  Thus, when the treated material is supported and supplied to the support surface of the supply conveyor, the treated material is held between the pair of crushing rollers and conveyed, and in the conveyance process, the glass of the treated material is crushed and broken. The glass piece is conveyed while adhering to the sheet, and a part of the glass piece peels off from the sheet and falls. In this case, the feed conveyor has a non-perpendicular angle to the plane passing through the axial center of the pair of crushing rollers, so that the processing material is inclined and enters between the pair of crushing rollers. The processed material is forcibly bent by the crushing roller, so that the glass can be easily broken. Further, since the feed conveyor can be adjusted in angle, it can be set to an optimal angle at which the glass is easily broken. Thereafter, when the processed material is conveyed and reaches the scraping roller, the scraping roller scrapes off the glass piece of glass adhering to the sheet of the processed material. In this case, since the workpiece is pressed against the scraping roller by the pressing roller, the scraping is surely performed. For this reason, as in the prior art, the glass can be easily separated from the sheet without heating by the heater and shaving off the glass piece with the blade, speeding up of the separation can be achieved, and the separation efficiency is improved. Can be

  Then, if necessary, the pair of crushing rollers are provided with one crushing roller corresponding to the glass surface of the processing object and the other crushing roller corresponding to the sheet surface, and the processing object is conveyed in a substantially horizontal direction. A lock mechanism for making the feed conveyor tiltable so that the bearing surface tilts downward from the upstream side to the downstream side, and lockably unlocking the feed conveyor at a required tilt angle It is set as the composition provided. As a result, the angle θ between the bearing surface supporting the glass surface of the object to the plane passing through the axial center of the pair of crushing rollers becomes an acute angle of θ <90 °. The angle θ is set to, for example, 45 ° ≦ θ ≦ 85 °. Therefore, the processed material is curved when it enters between the crushing rollers, but the glass surface is warped and tensile stress is applied to the glass surface, so the glass is easily cracked and the glass is further cracked. It can be made easy. In addition, since the processing object supported by the supply conveyor can be supplied along the inclination of the supply conveyor, the supply can be facilitated. Furthermore, the lock mechanism can be released to change the inclination angle of the supply conveyor, and adjustment can be easily performed.

  In addition, if necessary, it is provided on the upstream side of the pair of crushing rollers so as to be able to move forward and backward, and is advanced to stop at the downstream end of the processing object transferred by the supply conveyor to stop the transfer. And a stopper capable of moving to two positions of a passing position where it is retracted to release the locking of the downstream end of the processing object and pass the processing object, and a stopper driving unit for advancing and retracting the stopper It has composition. Since the workpiece can be supplied to the pair of crushing rollers after being stopped at one end, it can be reliably supplied.

  Furthermore, if necessary, the one crushing roller is rotatably supported by the machine base, the other crushing roller is supported by the support member, and the roller spacing between the one crushing roller and the other crushing roller is variable. Thus, the apparatus is supported on the machine base so as to move up and down, and the support member is moved up and down to provide a support member drive section that can be positioned at a required position. Since the support member can be moved up and down by the support member drive unit and the roller distance between the crushing roller and the other crushing roller can be changed, the glass can be crushed at an appropriate distance according to the thickness of the processing object. Can.

  Furthermore, if necessary, the scraping roller may be arranged parallel to the machine base in a substantially horizontal direction with respect to the one crushing roller, and the pressing roller may be arranged in the supporting member in a substantially horizontal direction with respect to the other crushing roller It has a parallel configuration. As a result, the distance between the scratching roller and the pressing roller can also be changed at the same time, so that the glass can be scratched at an appropriate distance in accordance with the thickness of the processing object.

  In addition, as necessary, a first drive unit rotationally driving the one crushing roller and rotating the scraping roller in synchronization with the one crushing roller, and a second drive unit rotationally driving the other crushing roller And the second drive unit is attached to the support member. Since the first driving unit synchronously drives one crushing roller and the scraping roller to rotate synchronously, it is possible to reliably convey the processed material. In addition, since the second drive unit is attached to the support member and moves up and down, the mechanism can be simplified.

Furthermore, if necessary, the first drive unit and the second drive unit forward the processed object from the upstream side to the downstream side based on the forward transfer command signal, and the processed object is transferred based on the reverse transfer command signal. It is configured to have a function to reverse the downstream side from the upstream side,
In the case of forward feeding in a state in which the processed material is held between the crushing rollers, it is detected that the upstream end of the processed material has reached a first position near the upstream side of the crushing rollers, The apparatus further comprises position detection means for detecting that the downstream end of the processed product has reached a predetermined second position when the processed product is transported backward.
A control unit for controlling the first drive unit and the second drive unit, the control unit sending out a normal feed command signal for sending the processed object forward on the downstream side; A reverse feed command for sending a reverse feed command signal for causing the processed object to be sent backward from the downstream side to the upstream side when the position detection means detects the first position after the forward feed command signal is sent from the send command signal sending means Retransmission for causing the forward command signal to be sent from the forward command signal sending means again when the position detection means detects the second position after sending the reverse command signal from the signal sending means and the reverse command signal sending means An output means and reverse feed number setting means for setting the number of times to enable the function of the reverse feed command signal sending means are provided. The processed material can be fed forward and backward to be repeatedly brought into contact with the crushing roller and the scraping roller, so that the glass piece can be reliably peeled from the sheet, and the separation efficiency can be improved.

  Furthermore, if necessary, the control unit sets an initial value E0 of the roller distance E between the one crushing roller and the other crushing roller at the time of the first forward feeding of the processed material, and Interval setting means for setting the adjustment value (E1 to En) of the above-mentioned roller interval E to E0 ≧ E1 ≧ ····· ≧ En every time the feed direction of the processed material is changed after sending. While moving the support member by the support member drive unit so that the initial value E0 of the roller interval E set in the above is obtained, and the feed direction of the process object is changed after the process object is normally fed first An interval control means is provided for moving the support member by the support member drive unit so that the adjustment value (E1 to En) of the roller interval E set in the interval setting means is provided. The setting by the interval setting means is set such that at least E0> En. Since the glass pieces are peeled off to some extent when moving in one direction, the processed material becomes thinner as it is, but when moving in the opposite direction, the roller distance between the crushing roller and the other crushing roller is As it becomes smaller, the holding by each crushing roller will not be insufficient, and therefore, the glass can be broken reliably. In addition, since the distance between the scraping roller and the pressing roller also decreases similarly, the scraping of the glass piece by the scraping roller can be reliably performed, and the separation efficiency of the glass piece can be further improved. it can.

  If necessary, the rotational speed of the one crushing roller and the scraping roller is Sa, and the rotational speed of the other crushing roller is Sb, the configuration is set such that Sa> Sb. For example, Sa = (1.1 to 3.0) Sb. As a result, the crushing roller on the glass side can be frequently brought into contact with the glass, the glass can be further finely crushed, and peeling by the crushing roller can be promoted, and the scratching roller also frequently contacts the glass piece. Since it can be brought into contact, scratching of the glass piece can be ensured.

  Furthermore, the apparatus is provided with a discharge conveyor for supporting and discharging the processed material discharged from the scraping roller, as required. It can be discharged smoothly.

  Furthermore, if necessary, a large number of transport rollers constituting a bearing surface for supporting the glass surface of the processing object by a group of generatrix having an axis parallel to the axis of the crushing roller and having the axial line parallel to the axis of the crushing roller. And a frame that rotatably supports the transport rollers. Since the workpiece can be transported and fed by its own weight by rolling the transport roller, the mechanism can be simplified accordingly.

  In addition, if necessary, the pair of crushing rollers is configured by providing crushing teeth with sharpened tips on the outer peripheral surfaces of each of the crushing rollers in a matrix, and the axial phase of the crushing teeth of one crushing roller and the other The configuration is such that the axial phase of the crushing teeth of the crushing roller is shifted. Thereby, the glass can be finely crushed, and the scratching with the scratching roller can be ensured.

  Furthermore, if necessary, the scraping roller is formed by providing in the outer peripheral surface thereof crushing teeth having sharpened tips in a matrix, and the pressing roller is formed so as to form an outer peripheral surface in a cylindrical plane and can be freely rotated. The configuration is Since the pressing roller is made rotatable, the scratching roller can be smoothly rotated to ensure scratching with the scratching roller without applying an undue load on the processing object.

  According to the present invention, since the glass of the processed material is crushed by the crushing roller and then the glass pieces are scraped off by the scraping roller, the processed material is heated by the heater and the glass pieces are not scraped off by the blade as in the prior art. Also, the glass can be easily separated from the sheet, so that the separation can be speeded up and the separation efficiency can be improved. Also, since the feed conveyor has a non-perpendicular angle to the plane passing through the axial center of the pair of crushing rollers, the processing object is inclined and enters between the pair of crushing rollers. The material is forcibly bent by the crushing roller, so that the glass can be easily broken, and also in this respect, the crushing and separation efficiency can be improved. Further, since the feed conveyor can be adjusted in angle, it can be set to an optimal angle at which the glass is easily broken. Further, also in the scraping by the scraping roller, since the processing material is pressed against the scraping roller by the pressing roller, the scraping can be surely performed.

The downstream sensor 72 also detects the upstream end Wb of the workpiece W discharged from the discharge conveyor 65 to stop the apparatus.

  Furthermore, the apparatus K includes a control unit 80 that controls the first drive unit 30 and the second drive unit 40. As shown in FIG. 9, the control unit 80 sends forward feed command signal transmitting means 81 for sending a forward feed command signal for sending the processing object W forward to the downstream side, and forward feed command signal from the forward feed command signal sending means 81. , And when the position detection means 70 detects the first position P1, the reverse feed command signal sending means 82 for sending a reverse feed command signal to cause the workpiece W to be reversely sent from the downstream side to the upstream side; After the backward command signal is sent from the forward command signal sending means 82, when the position detection means 70 detects the second position P2, a forward sending command signal is sent again from the forward feed command signal sending means 81. 83 and a reverse feed number setting means 84 for setting the number of times to make the function of the reverse feed command signal sending means 82 effective. In the embodiment, the number of times set by the reverse feed number setting unit 84 is one. That is, “forward feed → back feed → forward feed” is set to be performed on one processing object W. The number of times set by the number of times of back-feed setting means 84 may be appropriately determined according to the condition of peeling of the processing object W and the glass G of the processing object W. Also. A series of operations "forward feed → reverse feed → forward feed" is started by pressing the operation button 85, and the downstream sensor 72 detects the upstream end Wb of the workpiece W discharged from the discharge conveyor 65. It is finished.

  Further, the control unit 80 performs an initial stage of a roller interval E (a distance between a peak and a valley of the crushing teeth 11) between the crushing roller 10 (A) and the crushing roller 10 (B) at the first forward feeding of the processing object W. The adjustment value (E1 to En) of the roller interval is set to E0 ≧ E1E. While moving the support member 20 by the support member drive unit 23 so as to set the initial value E0 of the roller interval set in the interval setting means 86 and the interval setting means 86. After that, each time the feed direction of the workpiece W is changed, the distance for moving the support member 20 by the support member drive unit 23 so as to become the adjustment value (E1 to En) of the roller distance E set in the distance setting means 86 And control means 87. The setting by this interval setting means 86 is set so that at least E0> En. In the embodiment, E0> E1>...> En is set. That is, in the embodiment, since “forward feed → back feed → forward feed” is performed for one processing object W, E0, E1, and E2 are set, and E0 is greater than the thickness of the processing object W. Set a few mm smaller, and set E1 and E2 to be smaller by several mm in order. The set value may be appropriately determined in accordance with the treatment of the workpiece W and the peeling of the glass G of the workpiece W. In the embodiment, the support member 20 is positioned at the origin position at a larger interval than E0 before the start of the series of “forward feed → back feed → forward feed”.

  Furthermore, when one rotational speed of the crushing roller 10 (A) and the scraping roller 12 is Sa and the rotational speed of the crushing roller 10 (B) is Sb, Sa> Sb is set. For example, Sa = (1.1 to 3.0) Sb. The speed difference is not limited to this, and is set according to the property of the processing object W and the like. The setting of the rotational speed can be performed by the control unit 80. In addition to the above, the control unit 80 controls the operation of the electric cylinder device of the stopper drive unit 61 that moves the stopper 60 up and down and performs various controls.

Therefore, according to the glass separation apparatus K according to this embodiment, the inclination angle of the bearing surface Ma of the supply conveyor 50 is previously set to an appropriate angle by unlocking and locking of the lock mechanism 53 by trial operation or the like. . Since the inclination angle can be changed by unlocking and locking of the lock mechanism 53, adjustment can be easily performed.
And when separating glass G from processed material W taken out from a solar cell module, it becomes as follows. If it demonstrates also with reference to the flowchart shown in FIG. 10, first, the processed material W will be thrown into the supply conveyor 50 (S01). As a result, the workpiece W is transported toward the crushing roller 10 by its own weight by rolling of the transport roller 51 of the supply conveyor 50, and is stopped by the stopper 60 and stopped. Since the workpiece W supported by the supply conveyor 50 can be supplied along the inclination of the supply conveyor 50, the supply can be facilitated. At this time, the upstream sensor 71 detects whether or not the downstream end Wa of the workpiece W fed to the supply conveyor 50 has passed (S02), and the upstream sensor 71 is downstream of the workpiece W When the side end Wa is detected, it is determined that the object W is present (S02 Yes), and automatic operation by the push button of the operation button 85 is enabled (S03, S04). In this state, when the operation button 85 is manually pressed (S04 Yes), the automatic operation is started (S05).

  First, the support member 20 is moved downward by the support member drive unit 23, and the support member 20 is positioned so that the roller interval E becomes the initial value E0 from the origin position (S06). In this state, the stopper driving unit 61 retracts the stopper 60 to feed the workpiece W between the crushing rollers 10, and the forward feed command signal sending means 81 sends out the forward feed command signal, and based on the forward feed command signal. The first drive unit 30 and the second drive unit 40 are operated to feed the processed object W forward from the upstream side to the downstream side (S07). As a result, the processing object W is held between the pair of crushing rollers 10 and conveyed, the glass G of the processing object W is crushed in the conveyance process, and the broken glass pieces G of the glass G remain attached to the sheet S It is conveyed, and part of the glass piece Ga peels off from the sheet S and falls. In this case, in the supply conveyor 50, the angle θ between the bearing surface Ma and the plane Mb passing through the axial center of the pair of crushing rollers 10 is non-perpendicular to the plane Mb. Since the workpiece 10 is between 10, the workpiece W is forcibly bent by the crushing roller 10, so that the glass G can be easily broken. In particular, the processed material W is curved when it enters between the crushing rollers 10, but the glass surface becomes warped and a tensile stress acts on the glass surface, so that the glass G tends to be cracked, which is further enhanced. The glass G can be easily broken. In addition, since the supply conveyor 50 is adjusted to the optimum angle at which the glass G is easily broken, the glass G can be reliably broken. Further, since the phase of the crushing teeth 11 of one crushing roller 10 in the axial direction is shifted from the phase of the crushing teeth 11 of the other crushing roller 10 in the axial direction, the glass G can be finely broken. It is possible to ensure the scratching with the scratching roller 12 described later.

  Thereafter, when the workpiece W is conveyed and reaches the scraping roller 12, the scraping roller 12 scrapes off the glass piece Ga of the glass G attached to the sheet S of the workpiece W. In this case, since the workpiece W is pressed against the scraping roller 12 by the pressing roller 13, the scraping is reliably performed. In addition, since the pressing roller 13 is made rotatable, the scratching roller 12 can be smoothly rotated and the scratching by the scratching roller 12 can be ensured without applying an undue load to the processing object W. Also, since the relationship between the rotational speed Sa of the crushing roller 10 (A) and the scraping roller 12 and the rotational speed Sb of the crushing roller 10 (B) is set to Sa> Sb, the glass G side On the other hand, the crushing roller 10 (A) can be frequently brought into contact with the glass G, and the glass G can be further finely crushed, and peeling by the crushing roller 10 can be promoted, and the scraping roller 12 is also a glass piece Since it can be brought into contact with Ga frequently, scratching of the glass piece Ga can be ensured. For this reason, as in the prior art, the glass G can be easily separated from the sheet S without heating off with a heater and scraping off the glass piece Ga with a blade, and speeding up of separation can be achieved, and separation efficiency Can be improved.

  In the forward feeding process, the downstream sensor 72 detects whether the upstream end Wb of the object to be processed W has reached the first position P1 near the upstream side of each crushing roller 10 (S08). When it is detected that the first position P1 has been reached (S08 Yes), the first drive unit 30 and the second drive unit 40 stop the crushing roller 10 and the scraping roller 12 (S09). Then, the support member 20 is moved downward by the distance control means 87 via the support member drive unit 23, and the support member 20 is positioned so that the roller distance E changes from the initial value E0 to the adjustment value E1 (S10) . In this state, a reverse feed command signal is sent from the reverse feed command signal sending means 82, and the first drive unit 30 and the second drive unit 40 operate based on the reverse feed command signal to move the workpiece W downstream. To the upstream side (S11). As a result, the processing object W is again held between the pair of crushing rollers 10 and conveyed, and the glass G of the processing object W is crushed in the conveyance process, and the sheet S of the processing object W is scraped by the scraping roller 12. Is scraped off the glass piece Ga of the glass G attached to the. Therefore, since the processed material W can be repeatedly brought into contact with the crushing roller 10 and the scraping roller 12, the glass piece Ga can be reliably separated from the sheet S, and the separation efficiency can be improved.

  Moreover, since the glass piece Ga is peeled off to some extent when moving the processed material W in one direction, the processed material W becomes thinner accordingly, but in the case of this reverse feed, the crushing roller 10 (A) On the other hand, since the roller distance E with the crushing roller 10 (B) is reduced to the adjustment value E1, the holding by each crushing roller 10 is not insufficient, and therefore, the glass G can be reliably crushed. . In addition, since the distance between the scraping roller 12 and the pressing roller 13 is also reduced similarly, the scraping of the glass piece Ga by the scraping roller 12 can be reliably performed, and the separation efficiency of the glass piece Ga is further enhanced. Can be improved.

  In the reverse feed process, the upstream sensor 71 detects whether the downstream end Wa of the object to be processed W has reached the second position P2 near the downstream side of the scraping roller 12 (S12). When it is detected that the second position P2 has been reached (S12 Yes), the first drive unit 30 and the second drive unit 40 stop the crushing roller 10 and the scraping roller 12 (S13). Then, the support member 20 is moved downward by the distance control means 87 via the support member drive unit 23, and the support member 20 is positioned so that the roller distance E changes from the adjustment value E1 to the adjustment value E2 (S14) . In this state, the forward feed command signal is sent from the forward feed command signal sending means 81 by the re-sending means 83, and the first drive unit 30 and the second drive unit 40 operate based on the forward feed command signal. The object W is sent forward from the upstream side to the downstream side (S15). As a result, the processing object W is again held between the pair of crushing rollers 10 and conveyed, and the glass G of the processing object W is crushed in the conveyance process, and the sheet S of the processing object W is scraped by the scraping roller 12. Is scraped off the glass piece Ga of the glass G attached to the. Therefore, since the processed material W can be repeatedly brought into contact with the crushing roller 10 and the scraping roller 12, the glass piece Ga can be reliably separated from the sheet S, and the separation efficiency can be improved.

  In addition, since the glass piece Ga is peeled off to some extent when moving the processed material W in one direction, the processed material W becomes thinner accordingly, however, in the case of this forward feeding, with the crushing roller 10 (A) On the other hand, since the roller distance E with the crushing roller 10 (B) becomes smaller than the adjustment value E1 by the adjustment value E2, the holding by each crushing roller 10 does not become insufficient. It can be done. In addition, since the distance between the scraping roller 12 and the pressing roller 13 is also reduced similarly, the scraping of the glass piece Ga by the scraping roller 12 can be reliably performed, and the separation efficiency of the glass piece Ga is further enhanced. Can be improved.

  Then, in this normal delivery, when the downstream sensor 72 looks at the passage of the upstream end Wb of the processing object W (S16), and the downstream sensor 72 detects the upstream end Wb of the processing object W If there is no workpiece W (S16 Yes), the operation is stopped (S17), and the support member 20 is moved upward by the support member drive unit 23 to return to the original position (S18). The processed product W from which the glass G has been peeled is transferred by its own weight by rolling of the transfer roller 66 of the discharge conveyor 65 and discharged. In addition, the dropped glass piece Ga is received by the glass piece conveyance conveyor 43 and conveyed to the external storage section.

  FIG. 11 shows another example of the scraping roller 12. The scraping roller 12 is configured such that a plurality of rod-shaped members 12a having a rectangular cross-sectional shape having corner portions along the axis of the scraping roller 12 are provided at equal angular intervals on the outer peripheral surface thereof. Since the rod-like member 12a is along the axis of the scraping roller 12, it can scrape off the glass piece Ga at one time in the width direction of the processing object W, and the scraping efficiency of the glass piece Ga can be improved. it can. Further, since the rod-like member 12a has corner portions, the rod-like member 12a is easily caught on the glass piece Ga, so that the glass piece Ga can be reliably scraped off.

  In the above embodiment, the number of times set by the reverse feed number setting means 84 is set to one, that is, “reverse feed → forward feed” performed after the first forward feed to one processing object W is made once. However, the number of times set by the reverse feed number setting means 84 may be appropriately determined twice or more in accordance with the peeling of the processing object W and the glass G of the processing object W. Further, in the above embodiment, the number of pairs of crushing rollers 10 and the number of pairs of scraping rollers 12 and pressing rollers 13 are not limited to the above-described numbers, and two or more may be provided as appropriate. It can be changed. Furthermore, the shapes of the crushing roller 10, the scraping roller 12 and the pressing roller 13 are not limited to those described above, and they may be appropriately changed. Furthermore, in the above embodiment, although the case of the glass G of the solar cell module has been described as the processing object W, the present invention is not necessarily limited thereto, and glass used for devices such as liquid crystal television and plasma television Of course, it may be applied to various glasses.
