Description

TECHNICAL FIELD The present invention relates to a peeling device for a block of broken glass adhered to the surface of a resin sheet.

The use of renewable energy is being promoted as a countermeasure against global warming. As one of them, photovoltaic power generation is spreading as a power generation method that leads to the reduction of greenhouse gas emissions. On the other hand, some of the photovoltaic panels that have been introduced so far have reached the end of their service life and have been discarded, or have been damaged due to accidents during construction or stone throwing. In the future, solar power generation panels will be discarded according to the number of solar panels that have been popularized so far (see Non-Patent Document 1). Large-scale natural disasters, which have been increasing in recent years, have also caused damage to a large number of photovoltaic panels. A peeling device that separates and recovers the glass is particularly desired so that the photovoltaic panels that will be discarded in large quantities in the future can be recycled and the resources can be effectively reused.

The photovoltaic panel 100 as described above is composed of a plurality of materials having different physical and chemical properties, as shown in FIG. It is composed of an aluminum frame 108, glass (referring to cover glass) 104, solar cell 102, wiring material 106, sealing material 105, and back sheet 103 as a back surface protective material. There are various sizes, for example, length 1650 mm×width 990 mm×thickness 35 mm. In this specification, the solar cell 102, the sealing material 105, the wiring material 106, the sealing material 105, and the back sheet 103 as the back surface protective material are simply referred to as a "resin sheet" 107 other than the cover glass 104. When the aluminum frame 108 is removed, the thickness of the glass 105 is 3 to 6 mm, and the thickness corresponding to the resin sheet 107 is about 1 to 2 mm. Among these materials, the glass 104 must be separated from the resin sheet 107 for recycling. In this way, the photovoltaic panel has a structure in which the solar cells 102 are wrapped from both sides by a sealing material (resin layer) 105, which is also an adhesive such as EVA (ethylene-vinylacetate copolymer) resin. is glued to

One of the proposals is Japanese Patent Application Laid-Open No. 2002-200016. The glass separation device described in this patent document 1 proposes separating the cover glass 104 from the resin sheet 107 of the photovoltaic panel. More specifically, the cover glass 104 integrated with the resin sheet 107 after the aluminum frame 108 has been removed is placed on a pair of crushing roller tubes in which angular projections protrude evenly around the circumference of the cylinder on the outer peripheral surface. The glass is crushed by passing through After that, a columnar scraping roller having a plurality of protruding portions protruding at equal intervals in the axial direction on the outer peripheral surface of the crushed glass surface facing the support roller is rotated to crack the crushed mass. A glass separating apparatus has been proposed in which the glass pieces of the glass that have been removed are scraped off by the convex portion of the scraping roller.

Journal of Japan Society of Material Cycles and Waste Management Vol.30 No.6 2019

However, the prior art glass peeling apparatus has the following problems. That is, in the glass separation device described in Patent Document 1, the solar cell 102 and the back sheet 103 are attached to one surface with the sealing material 105, and the cover glass 104 is crushed by a pair of crushing rollers and fed. It is passed orthogonally between a pair of support rollers 30 and scraping rollers 40, which are opposed to each other at a horizontal axial position, so that the crushed glass can be scraped in a state where cracks remain. become. Therefore, efficient scraping by hooking the scraping blade on the crack was difficult.
Therefore, it is required to efficiently separate the cover glass 104 adhered with a sealing material or the like.

The present invention has been proposed to solve such problems. It is an object of the present invention to provide a glass peeling device.

In order to achieve the above object, the inventors have proposed the following apparatus for separating a lump of broken glass as means 1.
That is, in the panel assembly 101 in which the frame 108 is removed from the photovoltaic power generation panel 100 and the resin sheet 107 and the plate-like cover glass 104 are attached on the surface of the resin sheet, the plate-like glass portion is formed into a mass. This is a cracked glass block peeling device that separates cracked glass blocks from a resin sheet 107 .
First, a waste material having a block of cracked glass (in the present invention, for example, refers to a panel assembly 101 having a block of cracked glass) is heated from the glass surface side, and the resin sheet 107 is softened. That is, to soften the sealing material 105 that bonds the resin sheet 107 and the cover glass 104 , the heat is applied to the conveyed glass side with a length covering the entire width of the panel assembly 101 . Heaters are provided so as to face each other. Such heaters are arranged in units corresponding to the number of units capable of heating the resin sheet 107 according to the feeding speed of the bulk split glass and the resin sheet.
At least a pair of feeding rollers and a first pinch roller are provided downstream of the heater described above to sandwich and convey the panel assembly 101 by rotational drive.
Furthermore, it is possible to wrap the resin sheet surface side along the panel assembly 101 so as to open the cracks of the broken glass block, and to change the feeding direction, for example, from the horizontal direction to the vertical direction. A longer cylindrical or cylindrical drive roller is provided for power rotation about an axis.
Within the range of the winding angle from the winding start point (on the tangent line) where the resin sheet 107 of the panel assembly 101 contacts along the rotating outer peripheral surface of the drive roller to the winding end point (on the tangent line) discharged from the panel assembly 101. A columnar or cylindrical stripping roller is provided which is power-rotated about an axis and has scraping blades protruding intermittently from the entire peripheral surface thereof so as to substantially cover the width of the stripping roller.
When the peeling roller is pressed against the breakage of the cracked glass block wound around the drive roller and rotated at a higher linear speed than the drive roller, the scraping blade will bite into the breakage. , the bulky glass block is torn off from the resin sheet 107 .
At least a pair of discharge rollers and a second pinch roller are disposed downstream to discharge the resin sheet 107 from which the glass lumps have been peeled off and guide it to the lower collection tray.
There has been proposed an apparatus for separating a lump of broken glass having the components as described above.

According to the means 1 of the present invention, the resin sheet surface side of the panel assembly 101 having the block-shaped cracked glass in a block-shaped cracked state is driven in a cylindrical shape with a central angle in the range of about 60° to 130°, for example. When the glass is guided to be wound while being in contact with the roller, a force is applied to open the cracks in the glass block on the opposite side of the contact surface. For example, when a scraping blade of a peeling roller having a square cross section is pressed against the glass surface in such a state and rotated at a linear speed higher than the linear speed of the drive roller, the scraping blade moves the corner of the crack due to the difference in speed. , and a force is applied to separate the cracked glass mass from the resin sheet. For this reason, the glass that is broken into chunks is peeled off from the surface of the resin sheet one after another.

According to the means 1 of the present invention, it is possible to provide an apparatus for separating broken glass blocks that can effectively separate the broken glass blocks and collect the pieces of glass blocks.

(Other means of solving the problem)
Means 2, which is a subordinate concept of Means 1 described above, is proposed as a lumped glass in which an auxiliary heater is installed in the vicinity of the peeling roller and upstream to heat the range from the glass surface side of the lumped broken glass to the panel assembly 101 described above. This is a broken glass peeling device.

The auxiliary heater proposed in this way, even if the resin sheet 107 is heated by the heater provided in the means 1 to such an extent that it is softened, the above-mentioned waste is removed by the pair of feeding rollers and the first pinch roller. When the glass is passed through, the softening of the sealing material 105 is restored due to the release of heat, which may reduce the efficiency of scraping off the glass. For this reason, an auxiliary heater is used to compensate for the heat in the vicinity of the peeled portion upstream, which has the effect of enabling scraping off without lowering the efficiency. In particular, the above-mentioned auxiliary heater is located at the location where the cracks of the broken glass clumps open, i.e., the location facing the place where the broken glass is wound while being in contact with the cylindrical drive roller. When the resin sheet 107 is installed in the glass, the heat easily reaches the sealing material 105 directly from the crack of the glass, so that the heating effect of heating the resin sheet 107 is high, and the resin sheet 107 is easily peeled off.

Means 3, which is a subordinate concept of Means 1 and 2, is provided with a first stripping section composed of the driving roller and the stripping roller described above, and the waste is pressed against the driving roller downstream of the stripping roller. A second peeling roller is provided for scraping off the cracked lumps of glass that are left unpeeled, and the second peeling roller and the drive roller form a second peeling part. A detachment device for block broken glass was proposed.

In addition, as a modification thereof, the above-described first peeling section is provided, and a second driving roller is provided downstream of the first peeling section, at a position not in contact with the driving roller. A second peeling roller is provided for scraping off the cracked glass lumps left behind so as to press against the second peeling part by the second drive roller and the second peeling roller. We have proposed a peeling device for block broken glass.

Further, as another modification, the above-described first peeling portion is provided, and at a position not in contact with the drive roller downstream of the first peeling portion, in order to scrape off the cracked glass lumps left behind by the peeling, a A third peeling roller provided with symmetrical spiral ridges (groove blades) is provided. A stripping apparatus for broken glass blocks is proposed, in which a stripping pan installed so as to partially wrap the glass is extended in the axial direction, and the third stripping roller and the stripping pan constitute a second stripping section.

In this way, even if a glass lump is left behind in the first peeling unit due to the installation of the second peeling unit, the remaining glass lump can be reliably peeled off by the second peeling unit. become.
Furthermore, in the case of the modified example, when a second driving roller having a diameter smaller than that of the first driving roller is provided, the winding curvature of the second driving roller becomes small, so that the broken glass block is It is possible to open even the fine grains of the powder, and it is possible to improve the efficiency of the scraping work.
In particular, when the third peeling roller and the peeling pan constitute the second peeling portion, the winding angle and twist lead amount of the peeling pan for the remaining glass lumps can be arbitrarily set, thereby enabling continuous peeling. Thus, the peeling force can be continuously applied, and the remaining glass lump can be reliably peeled off.

Means 4, which is a subordinate concept of Means 3, is proposed by providing a tip detection sensor for detecting the tip of the resin sheet 107 that has passed through the nipping portion between the discharge roller and the second pinch roller, and based on the detection signal, Control of the rotational direction and linear velocity of the second peeling roller in the second peeling section, for example, control of reversing the rotational direction, or even rotation in the same direction, is faster than the linear velocity of the drive roller in the first peeling section. Control is performed to slow down the linear velocity, and the direction of the peeling force applied to the broken glass lumps in the first peeling unit is opposite to the conveying direction for the lumps of glass left unpeeled in the second peeling unit. We are proposing a peeling device for block broken glass that applies a peeling force from the opposite direction by applying a force in the direction of .

This is because when the leading end of the resin sheet 107 passes through the nipping portion between the discharge roller and the second pinch roller, the waste is separated from the feeding roller, the first pinch roller, the first drive roller, the first peeling roller, and the discharge roller. and the second pinch rollers, and can be stably conveyed in the discharge direction even if a force is applied in the direction opposite to the conveying direction at the second peeling portion. . In other words, the waste lump-like glass mass applies a peeling force in the same direction as the direction of the peeling force generated at the first peeling portion from its tip to the second peeling portion. After passing through the nipping portion between the discharge roller and the second pinch roller, it is possible to apply a force in the direction opposite to the conveying direction at the second peeling portion, and the peeling stress that has been once applied is removed again in the direction opposite to the conveying direction. The peeling effect is further enhanced by applying a peeling force from the surface.

Furthermore, as a modification, when the second peeling unit is configured with the third peeling roller and the peeling pan, the above-described leading end detection sensor is not necessarily provided, and the rotation direction and the line position of the third peeling roller Speed control is no longer necessary, and as described above, by arbitrarily setting the winding angle of the stripping pan and the amount of twist lead for the remaining glass mass, the waste can always be continuously coated from the tip to the end of the first pan. In the peeling portion, a peeling force can be continuously applied in a direction different from the direction of the peeling force applied to the broken glass block (a direction perpendicular to the direction in this embodiment), and the remaining glass lumps can be reliably peeled off. Become. In addition, even a glass block that has been broken and reduced in height can pass through a gap that is slightly wider than the thickness of the resin sheet 107, so that it can be peeled off more reliably.

An embodiment of the present invention will now be described with reference to FIGS.
First, an apparatus 1 for separating block broken glass includes a base frame 2 composed of a plurality of angles, a conveyer unit 300, a carrier unit 400, a separating roller unit 200, a collection box 5 for collecting and storing glass pieces 104c, a base and a base. A sheet recovery table (not shown) is provided below the frame 2 so as to fold the resin sheet 107 from which the glass piece 104c has been removed.

The transport conveyor unit 300 is provided with a plurality of conveyor rollers 302 on a conveyor base 301. The frame 108 is removed from the photovoltaic panel 100, the pre-crushed panel assembly 101 is placed, and the conveyor unit 300 is sequentially placed. 400 sheets are automatically or manually supplied one by one. In the case of the photovoltaic panel 100, the above-mentioned crushed panel assembly 101 is, in many cases, about 5 to 30 mm long and 5 to 30 mm wide, and is in the shape of irregularly sized blocks such as ovals and circles. cracked. Sizes other than these may also be included depending on how they are broken.

The transport table unit 400 places the panel assemblies 101 one by one on a transport base 401 that is inclined from the transport conveyor unit 300 to the peeling roller unit 200, and the panel assembly 101 is placed from the cover glass 104 side. A plurality of heater units 410 are provided to heat the entire surface. Each heater unit 410 is attached to a connecting beam 402 that connects across the top of the transfer base 401 so that the panel assembly 101 can be heated from the cover glass 104 side. The heater unit 410 is provided with a heater 411 such as a ceramic heater, a sheathed heater, or an infrared heater such as a carbon heater. ing. (See Figure 2)

In addition, at least a pair of feed rollers 23 and a first pinch roller 24 are provided behind the plurality of heater units 410 so as to convey the panel assembly 101 by rotating while sandwiching it. The feeding roller 23 is driven to rotate in the direction of the arrow in FIG. The sheet is fed to the peeling roller unit 200 while being held. As for the drive relationship between the feed roller 23 and the first pinch roller 24, either one can be driven. Further, if a rotational driving force is applied to both rollers, the conveying force is further improved. In addition, since the feeding roller 23 and the first pinch roller 24 convey the panel assembly 101 heated by the heater unit 410 in the preceding stage, the surfaces thereof are coated with metal rollers or heat-resistant silicone rubber having high conveying power. Rollers are preferred.

The configuration of the peeling roller unit 200 according to the first embodiment of the present invention will be described in detail with reference to FIGS. 2 to 5. FIG.
The configuration of the peeling roller unit 200 is the structure shown in FIGS. 2 to 4. FIG. Between the left frame 11 (see FIG. 1) and the right frame 12 which are connected to each other by a beam 13, a drive roller 21 is rotatably supported and a peeling roller 22 is provided so as to face each other with a certain gap P therebetween. It is This interval P can be adjusted in advance, and is set to be narrower than the thickness Q of the panel assembly 101 . (See FIG. 4) Further, downstream of the drive roller 21, a discharge roller 25 and a second pinch roller 26 are provided so as to pull and discharge the panel assembly 101 wound around the drive roller 21. As shown in FIG.

The space between the left frame 11 and the right frame 12 is set wider than the lateral width of the panel assembly 101 to be conveyed. Between the nip portion (nipping portion) between the pair of feed rollers 23 and the first pinch roller 24 and the nipping portion X between the drive roller 21 and the peeling roller 22, the panel assembly 101 is positioned at the above-described nipping portion X. A lower guiding guide 61 and an upper guiding guide 62 extend in the direction of the center axis of the driving roller 21 so as to guide the driving roller 21 to the right direction. The discharge roller 25 is driven to rotate in the direction of the arrow in FIG. The resin sheet 107 is conveyed and discharged while being sandwiched.

Further, the resin sheet 107 is sandwiched at a constant interval from the nipping portion X between the drive roller 21 and the peeling roller 22 to the nip portion (nipping portion) between the discharge roller 25 and the second pinch roller 26, A conveying guide 63 and a conveying guide 64 extend in the direction of the central axis of the driving roller 21 so as to guide the nipping portion of the discharge roller 25 described above. Although the discharge roller 25 and the second pinch roller 26 may be metal rollers, they are coated with the aforementioned heat-resistant silicone rubber, urethane rubber, or EPDM (ethylene propylene diene rubber) so as to improve the conveying force. Rollers are preferred.

The drive roller 21 is driven to rotate in the direction of the arrow in FIG. 3 by a drive means such as a drive motor (not shown), and conveys the back sheet 103 side of the panel assembly 101 by wrapping it around the back sheet 103 side. Further, in order to improve the conveying force of the panel assembly 101, the surface is a columnar or cylindrical roller with a diameter D and coated with silicone rubber having a high coefficient of friction and heat resistance. Its axis extends in the width direction of the panel assembly 101 and is rotatably supported between the left frame 11 and the right frame 12 . That is, when the panel assembly 101 is wound, it is wound with a radius of curvature R=D/2. (Refer to FIG. 3) The driving roller 21 is a metal grid roll which has been subjected to a treatment to improve the conveying force, for example, as described in Japanese Patent Application Laid-Open No. 2005-247572, or a metal roll coated with ceramics on its surface. A roller that is fired by spraying may also be used.

On the other hand, the peeling roller 22, which is arranged to face the drive roller 21 with a certain gap P, is driven by a drive means such as a drive motor (not shown) provided separately from the drive motor for the drive roller 21, as shown in FIG. It is driven to rotate in the direction of the arrow. It is a cylindrical or cylindrical metal roller made of steel or the like that has convex projections at regular intervals on its outer circumference and extends in the axial direction to substantially the same length as the drive roller 21 . For example, as shown in FIG. 5(a), the protrusions 22a extending in the axial direction form a scraping blade, and front portions 22c are provided on both sides of the tip. and a cutting edge rear portion 22e are provided. FIG. 5(b) shows another example of projections of the peeling roller 32, in which a plurality of projections (scraping blades) 32a are divided in the axial direction and alternately provided, and are separated by recesses 32b. For this reason, the projection 32a is erected independently to form a cutting edge front portion 32c, a cutting edge rear portion 32e, and a side end portion 32d. FIG. 5(c) is another example of the protrusions of the peeling roller 42. The protrusions ( A scraping blade 42a is independently erected, and the projection 42a is formed with a front edge portion 42c, a rear edge portion 42e, and a side end portion 42d. The stripping roller 42 has the advantage that it can be manufactured relatively easily as compared with the stripping roller 32 .

The glass pieces 104c (see FIG. 4) separated from the panel assembly 101 by the separation roller 22 are collected along the collection pan 51 provided near the holding portion X and accumulated in the space 5a of the collection box 5. .

Next, the positional relationship of the rollers, particularly the range of possible positions of the nipping portion X between the driving roller 21 and the peeling roller 22 will be described with reference to FIG.
Assuming that the wrap angle θ4 of the panel is the separation point F where the resin sheet 107 separates from the drive roller 21 from the entry point E where the panel assembly 101 enters the drive roller 21, possible positions of the sandwiching portion X are shown in FIG. 6, it is between the position X1 and the position X2 (the peeling roller 22 is indicated by a broken line in the figure). That is, between the position X1 wound by the winding angle θ1 from the entry point E and the position X2 back by the winding angle θ2 from the separating point F, even if it is within the range angle θ3 between the position X1 and the position X2. The jaw X can be anywhere. For example, if θ4 is 120°, θ1=10° and θ2=0°, the range angle θ3 is 110°. In the present invention, it is preferable to set the conditions in the range of θ1≧10° and θ2≧0°, because the lumped glass lumps are peeled off after the panel assembly 101 is wound around the drive roller 21 . Furthermore, θ1≧30° is preferable.

The operation of the present invention will be described below. First, the transport path and transport of the panel assembly 101 will be described with reference to FIGS. 3, 4, and 6. FIG.
When the feeding roller 23 rotates, the front end of the panel assembly 101 sandwiched between the feeding roller 23 and the first pinch roller 24 is guided by the lower guide 61 and the upper guide 62 and rushes toward the drive roller 21 . Guided to point E. Thereafter, along the inner surface 62a of the upper guiding guide 62, the panel assembly 101 can be bent to open the crack in the glass as the cover glass 104 is broken into chunks, and then rotated to gradually open the crack. The back sheet 103 side is wound around the driving roller 21 and guided to the nipping portion X between the driving roller 21 and the peeling roller 22 . Further, the cover glass 104, which has been broken into chunks at the clamping portion X, is peeled off from the panel assembly 101 while being sandwiched between the driving roller 21 and the peeling roller 22 (the effect of peeling will be described later). The remaining resin sheet 107 is guided by the conveying guides 63 and 64 with the conveying force of the driving roller 21 and the peeling roller 22, and separated from the driving roller 21 at the separation point F. The sheet passes through the nipping portion of the pinch rollers 26 of , and is discharged. After passing, the resin sheet 107 is placed on a sheet recovery table (not shown) so as to be folded.

The setting relationship between the conveying speed of the panel assembly 101 and the peripheral speed (the same as the linear speed in the tangential direction) due to the rotation of each roller will be described with reference to FIG.
The feeding roller 23 rotates in the direction of the arrow in the drawing at a peripheral velocity (linear velocity in the tangential direction) of a reference peripheral velocity V0. The panel assembly 101 pinched by the first pinch rollers 24 is naturally conveyed at the linear velocity V0. The driving roller 21 is also rotated at a reference peripheral speed V0 (linear velocity in the tangential direction) so that the panel assembly 101 does not loosen. Further, the discharge roller 25 also rotates at a peripheral velocity (linear velocity in the tangential direction) at a reference peripheral velocity V0.

On the other hand, the peeling roller 22 rotates at an outer peripheral speed (linear velocity in the tangential direction) V1 different from the reference outer peripheral speed V0 while sandwiching the driving roller 21 and the panel assembly 101 . This speed relationship is set to V0<V1. That is, the separation roller 22 exerts a force in the direction of pushing out the glass 104 due to the speed difference of "V1-V0". Here, the feeding roller 23, the driving roller 21, and the discharging roller 25 all rotate at the reference peripheral speed V0. Alternatively, they may be driven by a single drive motor using drive transmission means. Further, an electromagnetic clutch or the like may be used in the drive transmission means to control the engagement/disengagement of rotation of each roller. If the peeling roller peripheral speed V1 can be set, the peeling roller 22 can also be driven by the single drive motor described above. .

The action of peeling off the block of glass 104 from the panel assembly 101 will be described with reference to FIGS. 4 and 5 as well.
First, the panel assembly 101 heated from the glass 104 side by the plurality of heater units 410 in the carriage unit 400 softens the sealing material 105 . For example, the EVA resin mentioned above softens at about 70°C to 80°C. In this state, when the panel assembly 101 is conveyed while being nipped between the feed roller 23 and the first pinch roller 24, the back sheet 103 side wraps around the driving roller 21 from the entry point E and is curved with a curvature R. At this time, the cracks of the glass block 104a that has been broken into a block form are opened to form voids 104b. With respect to this gap 104b, the gap P is set so that the gap P<Q is narrower than the thickness Q of the panel assembly 101, and the projection 22a of the peeling roller 22 engages with the cutting edge front portion 22c of the projection 22a. caught in the corner of the crack. Furthermore, due to the peripheral velocity difference (linear velocity of "V1-V0") between the peripheral velocity V1 of the peeling roller 22, which is higher than the reference peripheral velocity V0 of the drive roller 21, the cutting edge front part 22c pushes the glass lump 104a in the direction of peeling, The glass lump 104a is peeled off against the adhesive force of the sealing material 105 to form a glass piece 104c. That is, the conditions of P<Q and V0<V1 are required for peeling of the glass lump 104a.

Since the panel assembly 101 cannot be transported until the sealing material 105 is softened, it is necessary to soften the sealing material 105 by heating from the glass 104 side with the plurality of heater units 410 in the carriage unit 400 . After that, by manually operating a switch or the like for starting the transport, the feed roller 23 is rotated and transported. Therefore, as shown in FIG. 3, a set sensor 80 is provided at a position in the vicinity of the upstream of the feed roller 23 at a distance L to detect the panel assembly 101, and a temperature sensor (not shown) detects the temperature of the panel assembly 101, or Alternatively, it is convenient to cause the conveying unit 400 to wait until the sealing material 105 softens for a predetermined waiting time T, and then automatically rotate the feeding roller 23 to convey the sealing material 105 . Since the plurality of heater units 410 can heat the panel assembly 101 while the panel assembly 101 is being transported, the heater units 410 need not be arranged over the entire vertical width of the panel assembly 101 .

Since the panel assembly 101 is rectangular and has a certain length, the rear end portion 101a of the panel assembly 101 passes through the pinching portion each time. do. When the rear end portion 101a passes through the nipping portion, the feed of the panel assembly 101 changes from the speed V0 at which the feed roller 23, the drive roller 21, and the discharge roller 25 are synchronized, and the load on the feed roller 23 at the rear end portion 101a is reduced. If the holding force of the driving roller 21 for the panel assembly 101 is weak, the panel assembly 101 may be quickly pushed into the nipping portion X at a speed of V1 by the feeding force of the peeling roller 22 having a relationship of V1>V0. . That is, it may be difficult to reliably separate the glass lump 104a using the speed difference between the peripheral speed V1 and the reference peripheral speed V0.

Therefore, even if the rear end portion 101a passes through the nipping portion between the feeding roller 23 and the first pinch roller 24, means for always reliably peeling off the glass lump 104a is required. FIG. 14 shows a control flow chart for controlling the peripheral speed of the peeling roller 22 to reliably peel off the glass lump 104a. At the same time, an outline of the detection control operation of the set sensor 80 will be described with reference to FIGS. 3 and 4. FIG. When the panel assembly 101 is set on the carrier unit 400 and the set sensor 80 is turned on, heating of the glass 104 side of the panel assembly 101 by the plurality of heater units 410 starts. When heated in this state for a predetermined standby time T, the sealing material 105 is softened (step 1). After that, the feeding roller 23, the driving roller 21, and the discharging roller 25 start rotating at the reference circumferential speed V0, and the feeding roller 23 and the first pinch roller 24 cooperate to start conveying the panel assembly 101. At the clamping portion X, the peeling of the glass lump 104a starts. (Step 2)

Further, the peeling operation progresses, the rear end portion 101a of the panel assembly 101 passes the set sensor 80, and the switching is from ON to OFF. When the trailing edge portion 101a is conveyed by a distance substantially equal to the distance L and passes through the nipping portion between the feeding roller 23 and the first pinch roller 24, the peeling roller 22 rotates at an outer peripheral speed V2 different from the outer peripheral speed V1. Rotation is started in the direction of the dashed arrow in FIG. 4, which is the direction opposite to the feed direction (step 3). Note that V2=0 (stop) may also be used. That is, the glass gob 104a is peeled off by the rear part 22e of the cutting edge opposite to the projection 22a of the peeling roller 22, receiving a force in the direction opposite to that in the case of peeling at the initial peripheral speed V1.

By doing so, even if the rear end portion 101a passes through the nipping portion between the feed roller 23 and the first pinch roller 24, the peeling roller 22 does not push at the outer peripheral speed V1, and is always stable. can apply a peeling force to the glass lump 104a. It should be noted that even if the peeling roller 22 rotates in the same direction as the feed direction of the drive roller 21, its outer peripheral speed V2 is much slower than the reference outer peripheral speed V0 of the drive roller 21, and the peripheral speed difference "V0 When −V2″ is large, the blade tip rear portion 22e of the peeling roller 22 engages the glass lump 104a to generate a braking force, and the glass lump 104a receives a force in the opposite direction to apply the peeling force to the glass lump 104a.

The configuration of the peeling roller unit 200 according to the second embodiment of the invention will be described with reference to FIG.
In the second embodiment of the present invention, a second heater unit 420 is provided as an auxiliary heater between the nipping portion of the feeding roller 23 and the first pinch roller 24 and the nipping portion X of the drive roller 21 and the peeling roller 22. was established. The second heater unit 420 has the same configuration as the heater unit 410 and is composed of a heater 421 and a reflector 422 . The second heater unit 420 has the same length so as to heat the width of the panel assembly 101 and extends along the axial direction of the drive roller 21 . According to the second embodiment, auxiliary heating is performed just before the clamping portion X, and the temperature of the sealing material 105 that has been softened by heating until the panel assembly 101 reaches the clamping portion X is removed and peeled off. Therefore, the glass lump 104a can be reliably peeled off at the holding portion X.

The configuration of the peeling roller unit 200 in the modified example of the second embodiment of the present invention will be described with reference to FIG.
In a modification of the second embodiment of the present invention, the position of the second heater unit 420 described above is a position wound around the drive roller 21 from the entry point E of the panel assembly 101 at a position angle α. It is provided so as to face the circumferential surface. By doing so, it is possible to heat the sealing material 105 directly from the gap 104b of the glass lump 104a, so that there is an effect of efficient heating.

The configuration of the peeling roller unit 200 according to the third embodiment of the invention will be described in detail with reference to FIG.
A third embodiment of the present invention is that the second peeling roller 30 is provided at a location different from the nipping portion X between the driving roller 21 and the peeling roller 22, thereby providing two or more locations for peeling. In FIG. 9, the second peeling roller 30 is rotated in the direction of the arrow at a peripheral velocity (linear velocity in the tangential direction) V3 by driving means such as a driving motor (not shown). Like the peeling roller 22, its outer circumference has convex projections (scraping blades) 30a at regular intervals as shown in FIG. It is a cylindrical or cylindrical roller made of metal such as steel. Further, a constant interval P2 is provided between the driving roller 21 and the second peeling roller 30, and the glass block 104a is peeled off while the panel assembly 101 is pinched by the pinching portion Y. The interval P2 has a relationship of P≧P2, and is set narrower than the interval P of the clamping portion X. Further, the relationship between the outer peripheral speed V3 of the second peeling roller 30 and the outer peripheral speed V1 of the peeling roller 22 is V3≧V1.

Other parts configuration, conveying operation and peeling operation of the third embodiment of the present invention will be described. Most of the glass lumps 104a of the panel assembly 101 are peeled off at the clamping portion X, and the glass pieces 104c are accumulated in the collection box 5 by the collection pan 52. . The unpeeled glass lump 104a is conveyed further downstream and guided by the front guide 71 extending in the central axis direction of the drive roller 21 to the nipping portion Y between the drive roller 21 and the second stripping roller 30. be guided to

As described above, the clamping portion Y satisfies the relationship of P≧P2, so that a peeling force can be reliably applied to the unpeeled glass lump 104a. The glass pieces 104 c separated by the holding portion Y are guided to the collection pan 53 and accumulated in the space 5 a of the collection box 5 . The remaining resin sheet 107 is sandwiched between the discharge roller 25 and the second pinch roller 26 downstream and placed on a sheet recovery table (not shown) so as to be folded. In this way, by setting the places where the glass lump 104a is to be peeled off to be two locations, the clamping portion X and the clamping portion Y, the glass lump 104a can be reliably peeled off.

The configuration of the peeling roller unit 200 in the modified example of the third embodiment of the present invention will be described with reference to FIG.
In a modification of the third embodiment of the present invention, a second driving roller 29 is provided in parallel with the driving roller 21 at a location different from the nipping portion X between the driving roller 21 and the peeling roller 22, 2, the two separating rollers 30 are arranged so as to face each other, and the interval between the pinching portions Z of the second drive roller 29 and the second peeling roller 30 is set to the interval P2. Furthermore, the second drive roller 29 has a diameter D2 smaller than the diameter D of the drive roller 21. FIG. The second drive roller 29 is rotated in the direction of the arrow at a reference peripheral speed (linear speed in the tangential direction) V0 by a drive means such as a drive motor (not shown). As described above, the second peeling roller 30 is rotated in the direction of the arrow at the peripheral velocity (linear velocity in the tangential direction) V3 by a driving means such as a driving motor (not shown).

Other component configurations, conveying operation, and peeling operation in the modified example of the third embodiment of the present invention will be described. Most of the glass lumps 104a of the panel assembly 101 are peeled off at the clamping portion X, but there may be unstripped glass lumps 104a as in the third embodiment. The panel assembly 101 that has passed through the clamping portion X passes between a front guide 71 and a rear guide 72 that extend in the direction of the center axis of the drive roller 21 and winds around the second drive roller 29 . It is guided to the nipping portion Z between the second driving roller 29 and the second peeling roller 30 .

As described above, the clamping portion Z has a relationship of P≧P2, so that a peeling force can be reliably applied to the unpeeled glass lump 104a. The glass pieces 104 c separated by the holding portion Z are guided to the collection pan 53 and accumulated in the space 5 a of the collection box 5 . The remaining resin sheet 107 is sandwiched between the discharge roller 25 and the second pinch roller 26 downstream and placed on a sheet recovery table (not shown) so as to be folded.

Here, the diameter D2 of the second drive roller 29 is D>D2 with respect to the diameter D of the drive roller 21, and the curvature at which the panel assembly 101 winds around the second drive roller 29 is R2=D2/ 2, which is smaller than the curvature R at which the drive roller 21 is wound. For this reason, the glass mass 104a left unpeeled easily floats from the resin sheet 107, and the gap 104b of the crack opens wide, so that the projection 30a of the second peeling roller 30 can easily enter. As a result, the cutting edge front portion 30c of the protrusion 30a is caught in the gap 104b of the crack in the pinching portion Z, resulting in a difference in peripheral speed from the peripheral speed V3 of the second peeling roller 30, which is higher than the reference peripheral speed V0 of the second driving roller 29. By (linear velocity of "V3-V0"), the cutting edge front part 30c pushes out the glass lump 104a in the peeling direction, and the unpeeled glass lump 104a can be more reliably peeled off.

The rotation control method of the second peeling roller 30 in the third embodiment of the present invention and the modification of the third embodiment will be described with reference to FIG.
This control is obtained by adding the control of step 4 after detecting the leading end portion 107a of the resin sheet 107 to FIG. In FIG. 9, a tip detection sensor 81 is provided downstream of the nipping portion between the discharge roller 25 and the second pinch roller 26, and the tip portion 107a of the resin sheet 107 can be detected.

When the resin sheet 107 remaining after the glass lump 104a is peeled off at two locations, the clamping portion X and the clamping portion Y or the clamping portion Z, passes through the clamping portion of the discharge roller 25 and the second pinch roller 26, it goes downstream. The distal end portion 107a is detected by the distal end detection sensor 81 located. At this stage, the entire length of the panel assembly 101 from the discharge roller 25 to the feed roller 23 is sandwiched between all the rollers.

Therefore, when the leading end portion 107a is detected by the leading end detection sensor 81 and changes from OFF to ON, the drive roller 21 or the second drive roller 29 and the panel assembly 101 are rotated at the outer peripheral speed V3 in the feeding direction until then. The second peeling roller 30 is rotated in the opposite direction to V3 at an outer peripheral speed V4 (indicated by a dashed arrow in FIGS. 9 and 10). Since the panel assembly 101 is suspended by all rollers to be driven, a sufficient force in the feeding direction is secured, and the panel assembly 101 continues to be fed at the linear velocity V0. (Step 4)

On the other hand, when the second peeling roller 30 is reversely rotated in the opposite direction to V3 at an outer peripheral speed V4 (indicated by the dashed arrow in FIGS. 9 and 10), the unstripped glass lump 104a has a sandwiched portion. At X, a peeling force opposite to the force in the peeling direction received by the cutting edge front portion 22c (see FIG. 5A) is applied. That is, a peeling force is applied to the glass lump 104a from the opposite direction by the blade tip rear portion 30e (see FIG. 5(a)). In this way, by applying another peeling force from a direction different from the direction in which the peeling force was once applied, the peeling becomes even easier. The shape of the scraping blade portion of the second peeling roller 30 is similar to that of the peeling roller 22, and has projections 30a on the outer circumference, and has the shape of the blade portion shown in FIG. 5(a). ing.

Also, the peripheral speed V4 may be V4=0, but if the peripheral speed is slower than V0 and rotates in the opposite direction (in the direction of the dashed arrow in the figure), the separation becomes even easier. Even if the rotation of the second peeling roller 30 is the same direction as the feed direction of the driving roller 21 and the second driving roller 29, the outer peripheral speed V4 of the driving roller 21 and the second driving roller 29 is When the peripheral speed difference "V0-V4" is large, the blade tip rear portion 30e of the second peeling roller 30 engages with the glass lump 104a to generate a braking force. It is possible to apply a peeling force to the glass lump 104a by receiving a force in the opposite direction.
The main point here is that in a device having a structure in which peeling is performed at a plurality of locations in the sandwiching portion X and the sandwiching portion Y or the sandwiching portion Z, the peeling force applied at the downstream peeling portion is in a different direction from the peeling force received at the upstream peeling portion. Controlling the application of force has the advantage of making peeling even easier. This point also applies to the fourth embodiment, which will be described later.

As in the second embodiment, a second heater unit 420, which is an auxiliary heater indicated by a dashed line in FIG. , the peeling at the clamping portion Z can be effectively performed. That is, by providing the second heater unit 420 as an auxiliary heater in at least one of the two locations immediately before the clamping portion X and the clamping portion Z, the softening of the sealing material 105 is assisted and the glass mass is heated. There is an advantage that the peeling of 104a can be performed more effectively. When there are a plurality of peeling portions, an auxiliary heater unit is provided immediately before at least one of the peeling positions to heat the glass lump 104a more effectively.

The configuration of the peeling roller unit 200 according to the fourth embodiment of the invention will be described in detail with reference to FIGS. 11, 12 and 13. FIG.
A fourth embodiment of the present invention is that the third peeling roller 31 is provided downstream of the nipping portion X between the driving roller 21 and the peeling roller 22, and two peeling locations are provided. In FIG. 12, the third peeling roller 31 is rotated in the direction of the arrow at a peripheral velocity (linear velocity in the tangential direction) V5 by driving means such as a driving motor (not shown). Note that the relationship between the outer peripheral speed V5 and the reference outer peripheral speed V0 is V5≧V0.

As shown in FIGS. 11 and 13, the third peeling roller 31 has spiral grooves 31b which are divided into left and right portions from the vicinity of the approximate center in the axial direction, and which have substantially the same length as the width direction of the peeling roller 22. They are connected at a central groove portion 31a. As a result, the third stripping roller 31 is formed with a right spiral ridge portion 31c and a left spiral ridge portion 31d with different twist directions to the left and right from the substantially central portion. form a lead screw. Further, in the vicinity of the outer circumference, a gap H slightly wider than the thickness of the resin sheet 107 is provided, and the third peeling roller 31 is peeled so as to wrap around about 1/4 of the outer circumference of the third peeling roller 31 (indicated by area S in the figure). A pan 75 extends in the axial direction. The stripping pan 75 serves as a rear guide for guiding the panel assembly 101 sent from the nipping portion X to the third stripping roller 31, and guides the resin sheet 107 to the nipping portion between the discharge roller 27 and the second pinch roller 28. There is also a role of a guidance guide to guide. Further, a front guide 76 and conveying guides 77 and 78 extend downstream of the third stripping roller 31 so as to face the stripping pan 75 . Furthermore, the glass pieces 104 c peeled off by the third peeling roller 31 travel along the collection pan 55 and are accumulated in the collection box 5 .

The peeling action of the third peeling roller 31 in the fourth embodiment of the present invention will be described with reference to FIG.
On the panel assembly 101 guided to the gap H between the third peeling roller 31 and the peeling pan 75 , the unpeeled glass lumps 104 a remain on the resin sheet 107 . This glass lump 104a is guided so as to slip into the spiral groove 31b of the third stripping roller 31, and is subjected to a stripping force G in the arrow direction perpendicular to the feed direction by the left and right spiral ridges 31c and 31d. In the figure, the peeling force G is applied to the left and right from the central groove portion 31a in the directions of the arrows opposite to each other. The reason why the central groove portion 31a is divided into left and right is to prevent the resin sheet 107 from shifting to one side due to the peeling force. This is for peeling off 104a.

The gap H is set to be slightly wider than the thickness of the resin sheet 107. By winding the peeling pan 75 around the outer periphery of the third peeling roller 31 with the gap H therebetween so as to wrap about 1/4 of the circumference, the lengthwise direction of rotation is reduced. Since the peeling force can always be applied over a long distance in the lateral direction compared to the peeling distance in the direction, even small glass lumps 104a left unpeeled can be peeled cleanly. In order to always apply the peeling force in the horizontal direction, the range S in which the peeling pan 75 is wound around the outer periphery of the third peeling roller 31 is preferably between 45° and 180°. Further, the moving distance in the horizontal direction can be arbitrarily set by setting the winding range S and the twist angle of the third peeling roller 31 .

The fourth embodiment of the present invention has been described above, but the main point here is that in an apparatus having a structure in which peeling is performed at a plurality of locations including the nipping portion X, the third peeling roller 31 and the third peeling roller 31 are used at the downstream peeling locations. By making the gap H between the stripping pans 75 slightly wider than the thickness of the resin sheet 107, and by controlling the stripping force in a direction different from the stripping force received at the upstream stripping point over a long distance. Furthermore, it has the advantage of being easier to peel off. In terms of applying peeling forces in different directions, in the third embodiment and the modification of the third embodiment of the present invention, the tip 107a of the resin sheet 107 is detected and the second peeling roller 30 is controlled. Equivalently, in the fourth embodiment of the present invention, even if the rotation and direction of the third peeling roller 31 are not controlled, the waste is always continuously formed in lumps in the first peeling portion from the leading end to the trailing end. A peeling force can be continuously applied in a direction different from the direction of the peeling force applied to the broken glass (a direction perpendicular to the direction in this embodiment), so that the remaining glass lump can be reliably peeled off. In addition, even a glass lump that has been broken and reduced in height can pass through a gap that is slightly wider than the thickness of the resin sheet 107, so there is an advantage that it can be reliably peeled off.

As described above, the embodiment of the present invention has been described in detail, but the embodiment is not limited to this, and the peeling portion may be provided in any number of steps without departing from the gist of the present invention. , and other various configurations are possible.
For example, in the present invention, the peeling roller has projections (scraping blades) protruding intermittently on the entire peripheral surface and has been described as a columnar or cylindrical metal roller. I don't mind. Alternatively, a peeling roller may be provided with thin wire brushes made of steel or brass radially on the outer peripheral surface of the cylindrical or cylindrical roller.
Furthermore, as shown in FIG. 17, in the case of a waste product (panel assembly 111) having plate glass adhered to both sides with a resin sheet 117 sandwiched therebetween, the second drive roller 29 and the second peeling roller 29 are used at the second peeling section. By reversing the positional relationship in which the rollers 30 face each other, the broken lump-like glass lumps on one side are scraped off by the holding portion X of the first peeling section, and then the broken lump-like glass lumps on the other side are scraped off. can be scraped off by the pinching portion Z of the second peeling portion, it can also be used for peeling off a lump of broken glass in the laminated glass sandwiching the resin sheet 117 .
In addition, the present invention is a proposal for an apparatus for peeling off a glass block from a resin sheet for waste having glass in which sheet glass has been cracked into a block in advance. It goes without saying that the apparatus may be provided with a unit for crushing the plate glass in the preceding stage.
