Description

[Technical Field]

[0001] The present disclosure relates to a foreign matter removal device and a panel processing device used to remove foreign matter from fragments including a glass layer separated from a plate-shaped member. [Background technology]

[0002] Conventionally, the glass layer contained in solar panels, liquid crystal panels, etc. (hereinafter referred to as "solar panels, etc.") is subject to recycling and is therefore peeled off when the solar panels, etc. are discarded. Solar panels have a glass layer bonded to a back sheet on which battery cells are stacked via a sealing material, and the four sides are reinforced with frame materials. A connector to which a power transmission cable is connected is attached to the back of the solar panel. Therefore, when a solar panel is dismantled, the frame materials and connectors are removed first, and then the glass layer is peeled off from the back sheet.

[0003] In order to recover only the glass from the glass layer, it is necessary to remove foreign matter such as electric wires. For example, according to the invention described in Patent Document 1 below (hereinafter referred to as the "Publication 1 Invention"), this process involves a sieving process, a wind sorting process, an air table sorting process, and the like.

[0005] However, as mentioned above, in the invention of the first prior art document, the specific configuration of the screening process is not clear, and since the invention of the first prior art document goes through a wind sorting process and an air table sorting process, etc., the invention of the first prior art document is not capable of easily removing foreign matter.

[0006] The present disclosure has been proposed in view of the above-described circumstances, and aims to provide a foreign matter removal device and a panel processing device that can remove foreign matter with a simple configuration. [Means for solving the problem]

[0009] The foreign matter removal device according to the present disclosure is characterized in that the sieving unit has a vibration unit that vibrates the belt unit.

[0010] The foreign matter removal device of the present disclosure is characterized in that the pair of rollers are arranged at different positions in the vertical direction, so that the screening section is inclined, the belt section moves from the lower roller to the higher roller, and among the fragments on the belt section, the glass pieces move down against the movement of the belt section, and the foreign matter is transported in the direction of movement of the belt section.

[0011] The panel processing apparatus according to the present disclosure is characterized in that the above-described foreign matter removal device is provided downstream of a glass separation device that crushes and separates the glass layer from the plate-shaped member, and the glass separation device has a conveying section that conveys the plate-shaped member, and a rotary impact section that is positioned downstream of the conveying section facing the end of the plate-shaped member in the conveying direction and rotates downward from the top surface of the glass layer to separate the glass layer from the plate-shaped member, and a striking member with a joint is provided on the outer surface of the rotary impact section, and a support base is provided downstream of the conveying section that supports the plate-shaped member in a bent state facing downward, and the rotating impact section rotates to position the plate-shaped member on the support base on an extension of the joint of the striking member, and the striking member hits the bent portion of the plate-shaped member at a position where it is aligned on the extension of the striking member, so that the glass layer on the bent side of the bent plate-shaped member that is facing the conveying section is separated from the bent portion, and the fragments are transported to the foreign matter removal device. [Effects of the Invention]

[0012] The foreign matter removal device according to the present disclosure includes a hopper section into which fragments generated when a glass layer is crushed and separated from a plate-like member having a glass layer and a substrate layer to which the glass layer is attached are introduced; an input amount adjustment section disposed downstream of the hopper section and adjusting the amount of fragments transported downstream; a chute section disposed downstream of the input amount adjustment section; and a sieving section disposed downstream of the chute section and sieving the fragments into glass fragments and foreign matter other than glass fragments. The input amount adjustment section adjusts the amount of fragments transported to the chute section, and the fragments are leveled by the chute section. In other words, the fragments are not transported in large quantities to the sieving section or piled up there. While the fragments contain a mixture of glass fragments and foreign matter, the sieving section appropriately sieves the glass fragments from the foreign matter.

DETAILED DESCRIPTION OF THE INVENTION

[0014] In the foreign matter removal device according to the present disclosure, the sieving unit includes a belt unit wound around a pair of rollers and a plurality of protrusions protruding from the surface of the belt unit. Among the glass fragments transported to the sieving unit, relatively small glass fragments pass through the gaps between the protrusions, while relatively large foreign matter is caught by the protrusions. Therefore, the foreign matter can be removed with a simple configuration, and only the glass fragments can be extracted.

[0015] In the foreign matter removal device according to the present disclosure, the sieving unit includes a vibration unit that vibrates the belt unit. The vibration of the belt unit by the vibration unit promotes sieving. Therefore, foreign matter can be removed with a simple configuration, and only glass fragments can be extracted.

[0016] The foreign matter removal device according to the present disclosure has a pair of rollers arranged at different positions in the vertical direction, resulting in an inclined sieving section, and a belt section moving from a lower roller toward a higher roller. Glass fragments on the belt section move downward against the movement of the belt section, while foreign matter is transported in the direction of the belt section's movement. Among the fragments transported to the sieving section, relatively small glass fragments pass between the protrusions and move down the slope. Meanwhile, relatively large foreign matter gets caught on the protrusions and is transported upward by the belt section. Therefore, foreign matter can be removed with a simple configuration, and only glass fragments can be extracted.

[0017] The panel processing apparatus according to the present disclosure includes a foreign matter removal device provided downstream of a glass separation device that crushes and separates a glass layer from a plate-shaped member, the glass separation device including a conveying section that conveys the plate-shaped member, and a rotary impactor disposed downstream of the conveying section facing an end of the plate-shaped member in the conveying direction and rotating downward from the upper surface of the glass layer to separate the glass layer from the plate-shaped member, the rotary impactor having a joint provided on its outer surface, and a support base downstream of the conveying section that supports the plate-shaped member in a bent state downward, the rotary impactor rotating to rotate the rotary impactor to rotate the rotary impactor to rotate the rotary impactor so that the bent portion of the plate-shaped member is aligned with the extension of the joint of the impactor, and the glass layer on the bent side of the plate-shaped member that is bent toward the conveying section is separated from the bent portion, and the fragments are transported to the foreign matter removal device. This allows the glass layer to be reliably separated from the plate-shaped member, and allows only the glass fragments to be extracted from the fragments.

[0018] The following is a description of a foreign matter removal device and a panel processing device according to a first embodiment of the present disclosure. Figures 1 and 2 show a glass separating device 10 of a panel processing device 100 according to the first embodiment, and Figures 3 and 4 show enlarged views of essential parts of the glass separating device 10, illustrating the processing state. In the description of the glass separating device 10, as shown in Figures 1 and 2, the upstream and downstream sides are defined based on the direction in which the plate-shaped member 1 is conveyed, and the thickness direction of the plate-shaped member 1 is defined as the upper and lower sides. Furthermore, the direction parallel to the plate-shaped member 1 and perpendicular to the conveyance direction is defined as the rotation axis direction of the rotary impact unit 26, and the left and right sides are defined as the lateral sides.

[0019] 1, the panel processing apparatus 100 disassembles solar panels as plate-shaped members 1, and includes at least a glass separating apparatus 10 and a foreign matter removing apparatus 40 arranged downstream of the glass separating apparatus 10, with the apparatuses 10 and 40 arranged on the same line. Therefore, in the panel processing apparatus 100, the plate-shaped members 1 are processed by passing through the glass separating apparatus 10 and the foreign matter removing apparatus 40 in that order.

[0020] The plate-like member 1 has a glass layer and an attachment layer to which the glass layer is attached (details not shown). The attachment layer is made by adhering a back sheet to the rear surface of the battery layer with a sealing material, and a glass layer to the front surface with a sealing material. A connector is attached to the rear surface of the back sheet. The laminate of the glass layer and attachment layer is surrounded on all sides by a frame. The frame and connector are separated from the plate-like member 1 in advance by a frame disassembly device (not shown).

[0021] The plate-shaped member 1 from which the frame and connector have been removed is transported from the frame dismantling device to a panel inverting device (described in detail later) with the glass layer facing downward, and in the panel inverting device, the plate-shaped member 1 is turned to a position with the glass layer facing upward. Next, the plate-shaped member 1 is transported to a glass separating device 10.

[0022] The glass separating device 10 is disposed downstream of the panel inverting device and serves to crush and separate the glass layer from the plate-shaped member 1. While conveying the plate-shaped member 1, the glass separating device 10 breaks and peels off the glass layer 2 with a rotary striking unit 26.

[0023] 1 and 2, the glass separating device 10 has a conveying section 11 that conveys a plate-like member 1 (see FIG. 4), and a glass separating section 15 that is arranged downstream of the conveying section 11. The conveying section 11 has a conveying-side base frame section 12, a rail section 13 that is placed on the conveying-side base frame section 12, and a heating section 14 that is arranged downstream of and above the rail section 13. The heating section 14 is, for example, an infrared heater, and faces the rail section 13 with a gap therebetween.

[0024] The glass separating unit 15 has a separation-side base frame unit 16, a transport support unit 17 and a rotary impact unit 26 mounted on the separation-side base frame unit 16, a recovery unit 37 attached to the lower part of the separation-side base frame unit 16 between the transport support unit 17 and the rotary impact unit 26, a first drive unit 38 that operates the transport support unit 17, and a second drive unit 39 that operates the rotary impact unit 26. Each of the drive units 38, 39 is, for example, a motor.

[0025] The transport support unit 17 is located beyond the downstream end of the transport unit 11. The transport support unit 17 includes two support rollers 18 (upper and lower), a first pulley 21 connected to the right end of the support rollers 18, and a support base 25 located downstream of the support rollers 18. The support rollers 18 are arranged coaxially facing left and right, with an upper roller 19 and a lower roller 20 facing each other with a gap between them. The first pulley 21 is coaxially connected to the right end of the upper roller 19. The first pulley 21 is connected to the first drive unit 38 via a first belt 23. The support base 25 is flat and elongated both left and right, and is fixed in a substantially horizontal position. The rotary impact unit 26 is located downstream of the transport support unit 17. The rotary impact unit 26 is elongated both left and right, and the second pulley 22 is connected to its left end. The second pulley 22 is linked to a second drive unit 39 via a second belt 24. The collection unit 37 is a box that is open at the top.

[0026] Here, the transport support portion 17 and the rotary impact portion 26 will be described in detail with reference to the drawings.

[0027] 3 and 4, the rotary striking section 26 has a rotary shaft section 27, which is a rotary shaft, a plurality of support body sections 28 attached to the rotary shaft section 27 and aligned in the direction of the rotary shaft, and a plurality of striking members 31 connected to the outer surface of the support body section 28. The rotary shaft section 27 passes through the center of the support body section 28, and three points on the outer periphery of the support body section 28 protrude outward. In other words, valleys 30 are formed between each of the protruding sections 29. The three protruding sections 29 are arranged at equal intervals on the outer periphery of the support body section 28, and a striking member 31 is connected to each of them.

[0028] The striking member 31 has a connecting portion 34 connected to the protruding portion 29 of the support body portion 28 via a first joint portion 32, and a striking body portion 35 connected to this connecting portion 34 via a second joint portion 33. With this configuration, the striking member 31 can bend freely like a chain at each of the joint portions 32, 33. The connecting portion 34 is a pair of flat links. The striking body portion 35 has a head portion 36 whose tip is formed to protrude out to the left and right sides.

[0029] Adjacent support body portions 28 are fixed to the rotation shaft portion 27 in a staggered manner. More specifically, the support body portions 28 are arranged with an offset of, for example, approximately 60 degrees in the rotational direction so that the protruding portions 29 of adjacent support body portions 28 are positioned in the valley portions 30 of the support body portions 28. Therefore, in each support body portion 28, the striking members 31 adjacent to each other in the rotational axis direction are arranged with an offset in the rotational direction, and the left and right ends of the heads 36 of the striking members 31 overlap when viewed from a direction perpendicular to the rotational axis direction (see FIG. 3).

[0030] The rotary impact section 26 is disposed with a gap X between it and the downstream end of the support base section 25 of the transport support section 17. More specifically, when the rotary impact section 26 is rotated, a gap X is provided between the tip of the head 36 of the impact main body section 35 and the tip of the support base section 25. The gap X is approximately the same as the thickness of the plate-like member 1 and is adjusted depending on the type of plate-like member 1. A recovery section 37 is disposed below the gap X (see FIG. 2).

[0031] In the glass separating device 10 configured as described above, the plate-shaped member 1 is placed on the rail section 13 of the conveying section 11 with the glass layer 2 facing upward. The glass layer 2 of the plate-shaped member 1 conveyed by the conveying section 11 is heated by the heating section 14 as necessary. The presence or absence of heating and the degree of heating vary depending on the plate-shaped member 1. The plate-shaped member 1 is conveyed while being sandwiched from above and below by support rollers 18, and is placed on the support base section 25. The downstream end of the plate-shaped member 1 placed on the support base section 25 faces the outer circumferential surface of the rotary impact section 26.

[0032] The rotary impact part 26 rotates in a direction (counterclockwise in FIG. 4) downward from the upper surface of the glass layer 2 of the plate-shaped member 1. When the rotary impact part 26 is not rotating, the impact member 31 is bent at each of the joints 32, 33 due to its own weight, but when the rotary impact part 26 rotates, the joints 32, 33 of the impact member 31 are stretched by centrifugal force, and the impact member 31 is stretched outward from the rotation axis.

[0033] As the plate-shaped member 1 is further conveyed, it is positioned in the gap X between the support base 25 and the rotary striking member 26. When the striking body 35 of the striking member 31 strikes the downstream end of the plate-shaped member 1 at a position where the plate-shaped member 1 on the support base 25 is aligned with the extension of the striking member 31 to which the joints 32 and 33 have been extended, the plate-shaped member 1 is supported by the support base 25 in a state where it is bent downward at approximately 90 degrees. At the same time, the glass layer 2 is broken, and a crack is formed in the glass layer 2 at the bent portion of the plate-shaped member 1. As the striking member 31 strikes the bent portion of the plate-shaped member 1 (the crack in the glass layer 2), the glass layer 2 on the bent side toward the conveying unit 11 is peeled off from the battery layer 4, with the bent portion as the boundary. At this time, the striking member 31 bends and flexes at the joints 32 and 33 due to the impact on the glass layer 2. When the deflecting striking member 31 is swung down on the upper end of the glass layer 2 on the bent side at the crack in the glass layer 2 at the bent portion, the glass layer 2 is peeled off from the battery layer 4 and falls as glass fragments 3. By repeating this operation, the glass layer 2 is shattered while the plate-like member 1 is transported, and the glass fragments 3 are accumulated in the recovery section 37.

[0034] The glass separating apparatus 10 operates as described above. Next, the effects of the glass separating apparatus 10 will be described.

[0035] The glass separating device 10 has a support base 25 at the downstream end of the conveying section 11, which supports the plate-shaped member 1 in a state where it is bent downward at approximately 90 degrees, and at a position where the striking member 31 hits the bent portion. That is, the plate-shaped member 1 placed on the support base 25 is bent at the tip of the support base 25, with the downstream side hanging down from the tip of the support base 25. At the same time, the glass layer 2 is broken, and a crack is formed in the glass layer 2 at the bent portion. When the striking member 31 hits the bent portion of the glass layer 2 (the crack in the glass layer 2), the glass layer 2 on the bent side toward the conveying section 11 is peeled off from the battery layer 4, with the bent portion as the boundary. Therefore, the glass layer 2 can be crushed and separated simultaneously, and the glass layer 2 can be smoothly peeled off from the battery layer 4.

[0036] Furthermore, since the glass layer 2 is peeled off in the direction in which the plate-like member 1 is discharged downward, the glass layer 2 can be peeled off smoothly without applying an excessive load.

[0037] The striking member 31 of the glass separating device 10 has a connecting portion 34 connected to the protruding portion 29 of the support body portion 28 via a first joint portion 32, and a striking body portion 35 connected to the connecting portion 34 via a second joint portion 33. This configuration allows the striking member 31 to bend freely at each of the joints 32, 33 like a chain. As the rotary striking portion 26 rotates, the striking member 31 stretches each of the joints 32, 33 due to centrifugal force, and becomes taut outward from the rotation axis. In this state, when the striking body portion 35 of the striking member 31 strikes the downstream end of the plate-like member 1, the striking member 31 bends at each of the joints 32, 33 due to the impact. The glass layer 2 is peeled off from the battery layer 4 by the bending striking member 31 and falls as glass pieces 3. This ensures that the glass layer 2 can be peeled off from the battery layer 4 reliably.

[0038] In the glass separating device 10, adjacent support body portions 28 are fixed to the rotation shaft portion 27 in a manner that they are alternately offset in the rotation axis direction. Therefore, in each support body portion 28, adjacent striking members 31 in the rotation axis direction are arranged with an offset in the rotation direction, and the left and right ends of the heads 36 of the striking members 31 overlap when viewed from a direction perpendicular to the rotation axis direction (see FIG. 3). In other words, for example, when viewed from above, the left and right ends of the heads 36 overlap with no gaps, so that the glass layer 2 can be peeled off evenly from the battery layer 4 in the rotation axis direction.

[0039] In the glass separating device 10, a heating unit 14 that heats the glass layer 2 faces a rail unit 13 of the conveying unit 11 (see FIG. 2). Heating the glass layer 2 by the heating unit 14 makes it easier to peel the glass layer 2 from the plate-like member 1.

[0040] Next, the foreign matter removal device 40 will be described with reference to the drawings. Figures 5 and 6 show the foreign matter removal device 40 according to a first embodiment.

[0041] In the collection section 37 of the glass separating device 10, not only glass fragments 3 but also foreign objects such as electric wires (not shown) are present as fragments generated when the glass layer 2 is crushed and separated from the plate-like member 1. The fragments are then sucked by a vacuum or the like (not shown) and transported to the foreign object removal device 40, where they are sieved. In the description of the foreign object removal device 40, as shown in Figures 5 and 6, the vertical direction is defined as up or down, the direction of movement of the belt unit 64 is defined as the front, the direction opposite to the direction of movement of the belt unit 64 is defined as the rear, and the directions of the rotation axes of the rollers that operate the belt unit 64 are defined as left and right sides. Furthermore, the positions of the fragments in the transport path are defined as the upstream side and downstream side.

[0042] As shown in Figures 5 and 6, the foreign matter removal device 40 includes a hopper section 42, a feed amount adjustment section 45, a chute section 50, and a sieving section 55 mounted in this order from top to bottom between a pair of facing removal-side base frame sections 41. Debris is fed into the hopper section 42 and passes through the feed amount adjustment section 45, chute section 50, and sieving section 55 in that order to be sieved. The hopper section 42 is mounted on the upper part of the removal-side base frame section 41. The feed amount adjustment section 45 is connected to the lower part of the hopper section 42 and is located downstream of the hopper section 42 in the conveying path. The chute section 50 is located below the feed amount adjustment section 45 and is therefore located downstream of the feed amount adjustment section 45 with respect to the conveying path. The sieving section 55 is located below the chute section 50 and is therefore located downstream of the sieving section 55 with respect to the conveying path.

[0043] The hopper section 42 has a funnel-shaped configuration, with an upper inlet 43 that is wide in the front-to-rear direction and a lower outlet 44 that is narrower than the inlet 43 in the front-to-rear direction. The hopper section 42 is wide in both the left and right directions. A feed amount adjustment section 45 is located directly below the outlet 44. The feed amount adjustment section 45 is formed by forming multiple protruding wall sections 47 on the outer peripheral surface of a cylindrical adjustment rotation member 46. The protruding wall sections 47 protrude outward from the outer peripheral surface of the adjustment rotation member 46 and extend left and right. The protruding wall sections 47 are arranged at equal intervals around the circumference of the adjustment rotation member 46. Therefore, grooves 48 extending left and right are formed between the protruding wall sections 47. The number, length, and spacing of the protruding wall sections 47 are optional. A motor is connected to the adjustment rotation member 46 as an adjustment drive section 49.

[0044] The chute section 50 is a member in which side wall sections 52 are connected to both left and right ends of a thin plate-shaped chute main body section 51. The side wall section 52 extends upward. A chute vibration section 53 is attached to the underside of the chute main body section 51. The chute vibration section 53 is located in the center of the chute main body section 51. The chute section 50 is inclined diagonally downward from the rear to the front. The front end of the chute section 50 is a discharge end section 54.

[0045] The sieving section 55 has a generally box-shaped box frame 56, a sieving main body 57 arranged inside the box frame 56, and a sieving vibration section 58 arranged below the sieving main body 57. The box frame 56 is open at its upper end and open at two locations, front and rear, at its lower end. The open upper end, a storage opening 59, is formed wider than the discharge end 54 of the chute section 50. The open lower ends, a rear sieving opening 60 and a front sieving opening 61, extend downward and narrow, and are formed narrower than the width of the box frame 56.

[0046] The sieving main body 57 includes a pair of front and rear rollers, a rear belt roller 62 and a front belt roller 63, and a belt portion 64 wound around the rear belt roller 62 and the front belt roller 63. The rear belt roller 62 and the front belt roller 63 are positioned at different positions in the vertical direction. Therefore, the sieving unit 55 as a whole is inclined obliquely upward from the rear to the front. A motor is connected to the rotation shaft of the front belt roller 63 as a sieving drive unit 65. Multiple protrusions 66 are formed on the surface of the belt portion 64. The protrusions 66 protrude outward from the surface of the belt portion 64. The protrusions 66 are, for example, rod-shaped like nails and are formed across the entire surface of the belt portion 64. The thickness, length, spacing, number, etc. of the protrusions 66 are arbitrary. The spacing between the protrusions 66 is sufficient to allow glass fragments to pass through.

[0047] The sieving vibration unit 58 is disposed inside the box-shaped frame 56 and attached to the box-shaped frame 56. The sieving vibration unit 58 is disposed below and in the center of the sieving main body unit 57. That is, the position of the sieving vibration unit 58 is between the rear belt roller 62 and the front belt roller 63, and is the center of the belt unit 64 wound around the rear belt roller 62 and the front belt roller 63.

[0048] The foreign matter removal device 40 is configured as described above. Next, the operation and effects of the foreign matter removal device 40 will be described.

[0049] When the adjustment drive unit 49 of the input amount adjustment unit 45 is operated, the adjustment rotation member 46 rotates. When debris is input into the hopper unit 42, the debris enters the groove 48 of the adjustment rotation member 46 from the discharge port 44, is transported little by little, and sent out to the chute unit 50. This adjusts the amount of debris transported to the chute unit 50. The rotation direction of the adjustment rotation member 46 is the direction in which the debris that enters the groove 48 falls toward the rear end of the chute unit 50 (counterclockwise in FIG. 5, arrow A1). Therefore, in the chute unit 50, the debris slides a long distance from the rear end toward the discharge end 54 at the front end, spreading and leveling the entire surface of the chute body piece 51.

[0050] The debris discharged from the discharge end 54 passes through the storage opening 59 of the box-shaped frame 56 of the sieving unit 55 and falls onto the belt unit 64 of the sieving main body 57. When the sieving drive unit 65 is operated, the front belt roller 63 rotates (clockwise, arrow A2 in FIG. 5 ), causing the belt unit 64 to move forward from the rear belt roller 62 toward the front belt roller 63, and the rear belt roller 62 moves in conjunction with the front belt roller 63. Relatively small glass fragments among the debris pass between the protrusions 66 and are transported backward down the slope against the movement of the belt unit 64 (arrow A3 in FIG. 5 ). On the other hand, relatively large foreign objects are caught by the protrusions 66 and are transported by the belt unit 64 and move upward toward the front (arrow A4 in FIG. 5 ). When the sieving vibration section 58 is operated, the vibration propagates to the entire belt section 64 via the box-shaped frame 56, the rear belt roller 62 and the front belt roller 63, thereby facilitating sieving.

[0051] The glass fragments are discharged from the rear sieving port 60 of the sieving unit 55 (arrow A5 in FIG. 5), while the foreign matter is discharged from the front sieving port 61 of the sieving unit 55 (arrow A6 in FIG. 5). In this way, the glass fragments and the foreign matter are properly separated. Therefore, the foreign matter can be removed with a simple configuration, and only the glass fragments can be extracted.

[0052] The following is a description of a panel processing apparatus according to a second embodiment of the present disclosure. Figure 7 shows a panel processing apparatus 200 according to the second embodiment, and Figures 8 to 13 show a panel inverting device 207 included in the panel processing apparatus 200.

[0053] 7, the panel processing apparatus 200 has at least a panel inverting device 207 and a glass separating device 10 arranged downstream of the panel inverting device 207, with the devices 10 and 207 arranged on the same line. Note that the panel processing apparatus 200 has a frame dismantling device arranged upstream of the panel inverting device 207. Therefore, in the panel processing apparatus 200, the plate-like member 1 is processed by passing through the frame dismantling device, the panel inverting device 207, the glass separating device 10, and the foreign matter removing device 40 in that order.

[0054] The plate-shaped member 1 from which the frame and connector have been removed by the frame dismantling device is reversed in position by the panel reversing device 207. That is, the plate-shaped member 1 is transported from the frame dismantling device to the panel reversing device 207 with the glass layer facing downward, and in the panel reversing device 207, the plate-shaped member 1 is reverted to a position with the glass layer facing upward (details will be described later). Next, the plate-shaped member 1 is transported to the glass separating device 10. The configuration of the glass separating device 10 is the same as in the first embodiment.

[0055] Next, the panel inverting device 207 will be described with reference to the drawings. Figures 8 to 10 show the panel inverting device 207. Figure 11 shows the operation of the suction unit 216. In the description of the panel inverting device 207, as shown in Figure 8, the conveying direction of the plate-like member 1 is defined as either forward or backward, and the inverting direction is defined as either leftward or rightward.

[0056] As shown in FIGS. 8 to 10 , the panel inverting device 207 includes a stage unit 208 on which the glass layer is placed with its surface facing downward, and an inverting unit 210 located adjacent to the right side of the stage unit 208. The stage unit 208 is formed of a metal frame and has a flat mounting table 209 on its upper surface. The inverting unit 210 is generally plate-shaped and is located above a base unit 211 also formed of a metal frame. The inverting unit 210 is located on the right side of the stage unit 208 and is connected to an inverting rotation shaft 217 that is connected to the base unit 211. The axis of the inverting rotation shaft 217 is oriented in the front-to-rear direction. A inverting drive unit 218 such as a motor is connected to the inverting rotation shaft 217 via a chain belt or the like. The inverting drive unit 218 is driven by a control signal from a control unit (not shown), causing the inverting rotation shaft 217 to rotate, thereby changing the orientation of the inverting unit 210. In more detail, the inversion section 210 rotates between a position located above the base section 211 (hereinafter referred to as the "transport preparation position P1", see Figure 10) and a position facing the mounting table 209 of the stage section 208 (hereinafter referred to as the "suction preparation position P2", see Figure 10).

[0057] The reversing unit 210 has a support frame 212 connected to the reversing rotation shaft 217, a pair of conveying units 214 connected to the support frame 212, a movable frame 213 connected to the support frame 212 and displaceable relative to the support frame 212, a suction unit 216 connected to the movable frame 213, and a long guide unit 215 fixed to an end of the conveying unit 214. The guide unit 215 is fixed to the end of the conveying unit 214 on the reversing rotation shaft 217 side, and protrudes from the plane of the conveying unit 214.

[0058] The conveying unit 214 is a flat belt that is elongated in the front-rear direction. The belt is wound around rollers (not shown), and the rotation of the rollers sends the belt forward. The suction unit 216 and the movable frame 213 are disposed in the center of the reversing unit 210, between the conveying units 214. The suction unit 216 is, for example, a plurality of vacuums made of rubber or silicone, and is arranged in the front-rear direction. A cylinder or the like displaces the movable frame 213 in response to a control signal from the control unit, thereby changing the degree to which the suction unit 216 protrudes from the conveying unit 214. More specifically, as shown in FIG. 11 , the suction unit 216 moves between a position on the same plane as the plane of the conveying unit 214 or recessed from the plane of the conveying unit 214 (hereinafter referred to as the "standby position P3"), and a position protruding from the plane of the conveying unit 214 (hereinafter referred to as the "suction position P4").

[0059] The panel inverting device 207 is configured as described above. Next, the operation and effect of the panel inverting device 207 will be explained with reference to the drawings. Figures 12 and 13 show the process of operation of the panel inverting device 207 according to this embodiment. Note that these figures only show a rough outline of the main parts, and other parts are omitted.

[0060] 12, the plate-shaped member 1 is placed on the mounting table 209 of the panel inverting device 207 with the glass layer facing downward. Initially, the inverting unit 210 is at the transport preparation position P1, and the suction unit 216 is at the standby position P3. Note that the frame and connector of the plate-shaped member 1 have been removed in advance by the frame dismantling device.

[0061] When the reversing unit 210 of the panel reversing device 207 rotates together with the reversing rotation shaft 217 (rotates counterclockwise in the figure) and reaches the suction preparation position P2, the suction unit 216 moves from the standby position P3 to the suction position P4. The reversing unit 210 in the suction preparation position P2 faces the adhered layer of the plate-shaped member 1 on the mounting table 209 (hereinafter referred to as the "facing position P5"), and the suction unit 216 comes into contact with and presses against the adhered layer, sucking the adhered layer and thereby adsorbing the plate-shaped member 1. In the facing position P5, the suction unit 216 in the suction position P4 protrudes further than the conveying unit 214 toward the plate-shaped member 1, so that the suction unit 216 reliably comes into contact with the adhered layer of the plate-shaped member 1 and adsorbs the plate-shaped member 1.

[0062] Even if the glass layer is cracked, since the glass is attached to the attachment layer and faces downward, when the plate-shaped member 1 is sucked upward, the glass layer remains attached to the attachment layer and does not shift, so the orientation of the glass layer of the plate-shaped member 1 can be easily reversed while maintaining a flat orientation.

[0063] 13, when the suction unit 216 that has adsorbed the plate member 1 moves from the suction position P4 to the standby position P3 in the facing posture P5, the adhered layer of the plate member 1 comes into contact with the flat surface of the conveying unit 214. When the conveying unit 214 comes into contact with the adhered layer, the plate member 1 is supported by the conveying unit 214. In this state, the reversing unit 210 rotates, so the plate member 1 is reversed without becoming worn out.

[0064] The inverting unit 210 rotates (clockwise in the figure) together with the inverting rotation shaft 217, and when the inverting unit 210 moves from the suction preparation position P2 to the transport preparation position P1 and assumes a position in which the glass layer of the plate-shaped member 1 faces upward, the suction unit 216 releases the plate-shaped member 1. More specifically, when the inverting unit 210 is at a position at least 90 degrees or more from the suction preparation position P2, the suction unit 216 stops suction. The plate-shaped member 1 slides on the inverting unit 210 due to its own weight toward the end of the inverting rotation shaft 217 (see arrow D in the figure), and hits the guide unit 215 at the end where it slides down. The plate-shaped member 1 that hits the guide unit 215 is adjusted to a position that is aligned with the guide unit 215. In other words, the position of the plate-shaped member 1 is automatically corrected to an appropriate position. Therefore, the plate-like member 1 is in an appropriate posture for processing in the glass separating device 10 in the next process, and the effort of correcting the posture is eliminated, which contributes to labor savings.

[0065] Here, in this embodiment, "the orientation of the plate-shaped member 1 with the glass layer facing upward" means an orientation in which the glass layer can be seen in a plan view. Therefore, it is not limited to an orientation in which the glass layer is horizontal.

[0066] The inverting unit 210 in the transport preparation position P1 supports the plate-shaped member 1 in a position where the glass layer faces upward (hereinafter referred to as the "support position P6"). In the support position P6, the conveying unit 214 is in contact with the layer to be attached, so the conveying unit 214 operates to feed the belt, thereby conveying the plate-shaped member 1. Because the belt is a single sheet, glass fragments do not get caught during transport. Furthermore, in the support position P6, the suction unit 216 in the standby position P3 does not protrude beyond the plane of the conveying unit 214, so it does not interfere with transport.

[0067] As described above, the reversing unit 210 sucks the plate-shaped member 1 with the suction unit 216 and rotates to change between the facing posture P5 and the supporting posture P6, thereby reversing the plate-shaped member 1. Therefore, the orientation of the glass layer of the plate-shaped member 1 can be easily reversed.
