Description

Technical Field

[0001] The present invention relates to the technical field of laminated glass preparation, and in particular to a laminated glass preparation device and an application method thereof. Background Art

[0002] Laminated glass is usually made of two layers of glass with a layer of glue. After the glass and the film are stacked, rolling and heat-sealing are required to make the laminated glass fit tightly with the film and ensure the transparency of the laminated glass. Laminated glass has been widely used because of its good safety, sound insulation, heat insulation and fire resistance.

[0003] The utility model patent with the existing authorization announcement number CN220923512U discloses a roller device and a laminated glass production system, comprising a frame and a first roller assembly and a second roller assembly arranged up and down; wherein the first roller assembly comprises a first roller, and the axial ends of the first roller are respectively rotatably connected to a first bearing; the second roller assembly comprises a second roller, and the axial ends of the second roller are respectively rotatably connected to a second bearing, and each of the second bearings is externally connected to a height adjustment device;

[0004] There is also a utility model patent with authorization announcement number CN215627646U, which discloses a small laminated glass processing device, wherein the lower cover plate is installed on the upper end of the bracket, and a plurality of cylinders are evenly distributed circumferentially on the upper end of the bracket, and the periphery of each cylinder is fixedly connected to the periphery of the bracket, and the movable rod of the cylinder is fixedly connected to the lower end of the upper cover plate, and the vacuum assembly is arranged between the upper cover plate and the lower cover plate, and the upper cover plate includes a first cover plate, a first heating assembly, and a plurality of elastic components, and the two ends of the elastic components are respectively fixedly connected to the lower end of the first cover plate and the upper end of the first heating assembly, and the periphery of the first cover plate is fixedly connected to the movable rod of the cylinder.

[0005] As described in the above technical solution, the lamination process of laminated glass is currently mainly carried out through heating and pressurization. In the first solution, the glass is bonded and pasted by rolling, and in the second solution, it is produced through vacuum heating. Some laminated glass is sent to a high-temperature and high-pressure autoclave during production, and the glass is bonded and formed by high temperature and high pressure.

[0006] In the current production process of laminated glass, two layers of glass are usually bonded together by film, and then placed on a conveyor line, and sent to a rolling mechanism or a heating structure by the conveyor line. The above-mentioned related technical schemes cannot detect defective glass due to the lack of relevant detection mechanisms. Some glass will have defects during the production process. Due to the influence of the existing preparation device structure, some glass will be damaged by collision during transportation. After the defective glass is pressed, it can only be scrapped and returned to the furnace, affecting production efficiency and wasting resources. Although there are many existing detection methods, defective glass can be removed by manual inspection, but the transportation of defective glass is also time-consuming. Therefore, a laminating device that can quickly identify defective glass and process it is needed.

[0007] In addition, in the existing tempered glass production process, the glass and film are usually stacked manually and then placed directly on the conveyor chain. During this operation, the glass is easily impacted. If there are foreign objects on the conveyor chain or the glass strength is low, the glass is prone to breakage and explosion. This problem also needs to be solved urgently. Summary of the invention

[0056] S9, transferring the laminated glass to between the lower heating module and the upper heating module through the reversing mechanism;

[0057] S10, the lower heating module and the upper heating module are closed together to perform hot pressing molding on the laminated glass.

[0058] The laminated glass preparation device and the application method of the present invention have the following beneficial effects compared with the prior art:

[0059] (1) By setting up a hot pressing module, it can heat press the laminated glass to melt the film, thereby firmly sticking the two layers of glass and improving the light transmittance; the upper heating module of the hot pressing module is provided with a carrier, and the carrier is provided with a camera module for detecting the laminated glass, so that it can quickly determine whether the laminated glass has defects, so as to avoid waste of resources and affect production efficiency caused by hot pressing; and a conveyor chain is provided between the two carriers, which is used to temporarily store defective glass, so that the defective glass does not need to be transported over a long distance, and production efficiency can be guaranteed; at the same time, the structure of the upper and lower layout of the hot pressing device and the defective glass storage place ensures the compactness of the laminating device, which can reduce space occupancy and improve operation convenience;

[0060] (2) By setting a bearing mechanism, the laminated glass can be carried and the posture of the laminated glass can be corrected, and the laminated glass can be lifted up by the lifting mechanism. Then, the laminated glass can be reversed by the reversing mechanism, and the posture of the laminated glass can be adjusted so that the laminated glass can face the hot pressing module, and the laminated glass can be sent into the hot pressing module. In this way, the posture of the laminated glass is correct, which is conducive to improving the yield of the finished product and reducing the situation of cracking caused by uneven stress distribution during the hot pressing process;

[0061] (3) The bearing mechanism supports the laminated glass by supporting cables, which can avoid the problem of laminated glass breaking due to excessive placement force when transporting the laminated glass.

[0062] (4) By connecting the servo motor to the support cable through the roller and connecting the tension sensor in series to the support cable, the tension sensor can be used to determine the force on the support cable, and then the servo motor drives the roller to rotate, so as to achieve tensioning of the support cable, thereby achieving stable support for the laminated glass and preventing the laminated glass from being damaged by colliding with the first electric push rod due to excessive deformation of the support cable;

[0063] (5) The reversing mechanism includes a rotating table and a universal ball module. The rotating table can be used to rotate the laminated glass so that the laminated glass is aligned with the hot pressing module. Then, the universal ball module can be used to send the laminated glass into the hot pressing module for hot pressing. When there is a problem of deviation of the laminated glass, the universal ball module can be used to fine-tune the attitude to ensure the correct position.

[0064] (6) By setting up an introduction mechanism, when the laminated glass is separated from the universal ball module and loses the moving power, the laminated glass can be pushed into the heating module to ensure the normal progress of the production process.

[0065] (7) A first laser and a second laser are provided to detect the transparency and bending shape of the glass respectively, so as to judge whether the glass has completed the interlayer normally. At the same time, the first laser and the second laser are detected to detect whether the bending shape of the glass is normal, so as to judge the state of the glass.

DETAILED DESCRIPTION

[0079] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0080] like Figures 1 to 10 As shown, the laminating device for preparing laminated glass of the present invention includes a first frame 1, a hot pressing module 2, a conveyor chain 3, a carrier 4, a camera module 5, a second frame 6, a bearing mechanism 7, a lifting mechanism 8, a reversing mechanism 9, an introduction mechanism 10, a clamping cylinder 11, a first laser 12 and a second laser 13.

[0081] like Figures 1 to 6 As shown, the hot pressing module 2 includes a lower heating module 21 and an upper heating module 22, wherein the lower heating module 21 is arranged on the first frame 1; the upper heating module 22 is arranged on a side of the lower heating module 21 away from the first frame 1, and the upper heating module 22 can be displaced relative to the lower heating module 21;

[0082] As in the above structure, the lower heating module 21 and the upper heating module 22 are used to perform a heating process on the laminated glass, and the laminated glass can be pressurized by a pressurizing component to ensure that the two layers of glass are tightly attached;

[0083] Specifically, the lower heating module 21 and the upper heating module 22 may adopt a chamber structure, and a heating component and a pressure component may be installed inside. Preferably, the lower heating module 21 and the upper heating module 22 may form a sealed chamber to seal the laminated glass, and then evacuate the chamber to apply high temperature and high pressure to the laminated glass in a vacuum state to ensure the molding stability of the laminated glass;

[0084] Specifically, the heating functions of the lower heating module 21 and the upper heating module 22 can be achieved by quartz lamp heating, hot air flow heating, electric heating, and the like.

[0085] like Figure 4 and Figure 6 As shown, the conveyor chain 3 is arranged on the upper heating module 22, and is used to convey the laminated glass with defects; a carrier 4 is arranged on each side of the conveyor chain 3, and the carrier 4 is connected to the upper heating module 22; a camera module 5 is arranged on the carrier 4, and the camera module 5 is used to detect the defects and edge contour of the laminated glass;

[0086] As in the above structure, the position between the two carriers 4 constitutes a defective glass storage station. When producing laminated glass, the laminated glass can be inspected by the camera module 5. One is to detect whether the laminated glass has surface defects. If the laminated glass has surface defects, it is very easy to cause stress concentration problems in the heating process, thereby causing breakage. Therefore, after the camera module 5 determines that the laminated glass has the next defect, the laminated glass can be directly sent between the two carriers 4 for storage, thereby avoiding the waste of time caused by transferring defective glass. When a certain amount of defective glass accumulates, it can be removed and recycled.

[0087] In this structure, the hot pressing device and the defective glass storage area are arranged up and down, which ensures the compactness of the laminating device, reduces space occupation and improves operation convenience;

[0088] In order to facilitate the transfer of defective glass, a conveyor chain 3 is provided between the two carriers 4 for conveying the laminated glass, so as to facilitate the removal of the laminated glass from between the two carriers 4;

[0089] Specifically, the conveyor chain 3 can be roller conveyor or chain conveyor, and a motor can be used as a power source.

[0090] If the camera module 5 determines that there is no abnormality in the laminated glass, it can be sent to the hot pressing module 2, and the laminated glass is pressurized and heated by the lower heating module 21 and the upper heating module 22, so as to achieve the bonding of the two layers of glass;

[0091] In some embodiments, the hot pressing module 2 is further provided with a rolling device to further press the laminated glass.

[0092] like Figure 4 As shown, the clamping cylinder 11 is arranged on the carrier 4, and the movable end of the clamping cylinder 11 corresponds to the conveying chain 3, and the clamping cylinder 11 cooperates with the conveying chain 3 to clamp the laminated glass with defects;

[0093] As in the above structure, the clamping cylinder 11 cooperates with the conveying chain 3 to clamp and fix the defective laminated glass on the conveying chain 3 to avoid the problem of the laminated glass falling due to the action of the upper heating module 22, thereby ensuring the stability of the application.

[0094] like Figure 2 As shown, the hot pressing module 2 further includes a linear guide rail 23 and a linear drive member 24, wherein the lower heating module 21 is connected to the upper heating module 22 via the linear guide rail 23 to achieve an opening and closing action; the linear drive member 24 is disposed on the first frame 1, and the movable end of the linear drive member 24 is connected to the upper heating module 22;

[0095] As in the above structure, when the hot pressing process is carried out, the upper heating module 22 is driven by the linear drive 24 to move, so as to achieve opening and closing with the lower heating module 21. When the upper heating module 22 moves, it is guided by the linear guide rail 23 to maintain stability, wherein the linear drive 24 can adopt displacement components such as cylinders and electric push rods.

[0096] As shown in the structure, four linear guide rails 23 and four linear drive members 24 are provided and located on the sides of the two carriers 4 .

[0097] In some embodiments, the linear guide rail 23 is eliminated, and only the upper heating module 22 is supported by the linear drive member 24, and four linear drive members 24 are still provided, and the four linear drive members 24 are in a rectangular array. When used, the two linear drive members 24 located at the entrance of the hot pressing module 2 for inputting the laminated glass are hinged with the first frame 1 and the carrier 4, and the guide rail part of the linear guide rail 23 is connected with the first frame 1. The two linear drive members 24 located at the exit of the hot pressing module 2 are fixed on the first frame 1 and hinged with the carrier 4.

[0098] In this way, when used, the two linear driving members 24 at the outlet do not move, while the two linear driving members 24 at the inlet move to lift the upper heating module 22 and the carrier 4, so that the tilting is achieved with the two linear driving members 24 at the outlet as the fulcrum, which can complete the automatic unloading work to discharge the defective laminated glass.

[0099] like Figures 1 to 7 As shown, the second frame 6 is arranged on one side of the first frame 1, and the second frame 6 includes a stacked upper layer 61 and a lower layer 62; the supporting mechanism 7 is arranged on the upper layer 61, and is used to support the laminated glass and correct the posture of the laminated glass; the lifting mechanism 8 is arranged on the lower layer 62, and the lifting mechanism 8 passes through the upper layer 61; the reversing mechanism 9 is arranged on the lifting mechanism 8, and the reversing mechanism 9 is used to adjust the direction of the laminated glass and transport the laminated glass to the hot pressing module 2.

[0100] As in the above structure, the carrying mechanism 7 is used to carry the laminated glass that has been stacked and to calibrate the laminated glass;

[0101] like Figure 1 and Figure 3 As shown, two bearing mechanisms 7 are symmetrically arranged, and the bearing mechanisms 7 include a first limit plate 71, a sliding bracket 72, a first electric push rod 73, a second limit plate 74 and a support cable 75, wherein the first limit plate 71 is arranged on the first frame 1; two sliding brackets 72 are arranged on the second frame 6; the cylinder body of the first electric push rod 73 is connected to the first frame 1, and the movable rod end of the first electric push rod 73 is provided with a second limit plate 74, and the cylinder body and the movable end of the first electric push rod 73 are respectively supported by a sliding bracket 72 for sliding support; one end of the support cable 75 is connected to the first limit plate 71, and the other end is connected to the second frame 6, and the middle section of the support cable 75 passes through the second limit plate 74;

[0102] As in the above structure, in the carrying mechanism 7, the laminated glass is supported by the supporting cable 75, so that the laminated glass can be prevented from being broken due to excessive placement force when the laminated glass is carried;

[0103] In conventional laminated glass production, glass and film are usually stacked and placed directly on a conveyor chain. If the placement force is too great, the laminated glass is easily broken by impact. However, the device uses support cables 75 to achieve flexible support, which can effectively prevent the laminated glass from being broken by impact.

[0104] Specifically, after the laminated glass is placed on the supporting cable 75, the first electric push rod 73 drives the second limiting plate 74 to move. At this time, the second limiting plate 74 moves along the supporting cable 75 until it cooperates with the first limiting plate 71 to achieve stable clamping of the laminated glass. In this way, even if the laminated glass is tilted, the displacement of the second limiting plate 74 can drive the laminated glass to straighten its posture, so that the two side edges of the laminated glass are parallel to the supporting cable, which is convenient for the subsequent feeding of the laminated glass into the hot pressing module 2;

[0105] Furthermore, flexible pads are provided on the first limiting plate 71 and the second limiting plate 74 to prevent the laminated glass from being broken during clamping.

[0106] like Figure 1 and Figure 6 As shown, the bearing mechanism 7 further includes a servo motor 76, a roller 77, a tension sensor 78 and a limit baffle 79, wherein the servo motor 76 is arranged on the second frame 6; the roller 77 is arranged on the output shaft of the servo motor 76; the tension sensor 78 is connected in series to the support cable 75, and the tension sensor 78 is located between the second limit plate 74 and the roller 77; the limit baffle 79 is arranged on the support cable 75, and the limit baffle 79 is located between the tension sensor 78 and the second limit plate 74;

[0107] As in the above structure, the servo motor 76 drives the roller 77 to rotate, so as to realize the winding and tensioning of the support cable 75, so as to avoid the problem that the support cable 75 is excessively deformed due to the weight when carrying the laminated glass, thereby causing the laminated glass to hit the first electric push rod 73 and be damaged;

[0108] Furthermore, the tension sensor 78 connected in series to the support cable 75 can determine the force applied to the support cable 75, and then drive the roller 77 to rotate through the servo motor 76 to adjust the tension of the support cable 75. This ensures that the support cable 75 is in a state of certain elasticity, neither too loose nor too stiff, so as to achieve stable support for the laminated glass and appropriate elastic buffering, thereby avoiding the problem of unstable placement of the laminated glass or impact damage.

[0109] After the quality range of the product is determined, the tensioning range of the support cable 75 will not be changed;

[0110] Specifically, the mass range of the product is set to X1 kg ~X2kg, and the tensioning range of the support cable 75 is the retracted and released length range of the support cable 75. Here, the judgment is made based on the angular displacement of the main shaft of the servo motor 76, that is, when producing laminated glass with a mass range of X1kg ~X2kg, the angular displacement of the main shaft of the servo motor 76 is between S1° and S2°. After running for a certain period of time, the self-inspection process is performed, and the main shaft of the servo motor 76 rotates to synchronously detect the size of the angular displacement and the detection value of the tension sensor 78. If the size of the angular displacement (that is, the reeling length of the support cable 75) does not match the tension detected by the tension sensor 78, it means that the support cable 75 has an extension problem. At this time, in order to avoid the support cable 75 from breaking, it needs to be replaced in time.

[0111] like Figure 5 and Fig.10 As shown, the lifting mechanism 8 is one of a hydraulic lifting platform, a pneumatic lifting platform or an electric lifting platform, and the reversing mechanism 9 includes a rotating platform 91 and a universal ball module 92, wherein the rotating platform 91 is arranged on the lifting mechanism 8, and the rotating platform 91 is used for reversing the laminated glass; the universal ball module 92 is arranged on the rotating platform 91, and is used for correcting the posture of the laminated glass and conveying the laminated glass to the hot pressing module 2;

[0112] As in the above structure, the lifting mechanism 8 can be a hydraulic lifting platform, a pneumatic lifting platform or an electric lifting platform; of course, the lifting mechanism 8 is not limited to a structural form, and it can be any structural form that can achieve lifting, such as a telescopic cylinder type, a scissor type, etc.;

[0113] The rotating table 91 in the reversing mechanism 9 is used to reverse the direction of the laminated glass. Usually, during production, the laminated glass spans the two supporting cables 75 in the length direction, and the hot pressing module 2 is usually in the feeding direction of the production line in the width direction. At this time, the laminated glass needs to be driven by the rotating table 91 to rotate 90° so that the width side of the laminated glass corresponds to the hot pressing module 2, so that the laminated glass can smoothly enter the hot pressing module 2;

[0114] In the conventional production process, after the glass is manually laminated, the glass will be directly placed on the conveyor chain. The width direction of the glass may not face the hot press unit directly, and the glass is placed obliquely on the conveyor chain as a whole. Therefore, the entrance of the hot press unit is usually set wider to facilitate the smooth entry of the glass. However, this will cause the hot press unit to occupy a large area. If the entrance of the hot press unit is reduced, the glass will be easily hit by the hot press unit if the tilt amplitude is too large. After the bearing mechanism 7 and the reversing mechanism 9 are provided, the problem of impact damage to the laminated glass can be avoided.

[0115] In some embodiments, the laminated glass needs to go through a rolling process. If the laminated glass is not in the correct posture when entering the rolling process, it is easy to cause stress concentration and breakage after rolling and subsequent processing. After lifting and reversing, or affected by external factors, the laminated glass is prone to slight deviation, which will affect the production yield of the laminated glass to a certain extent. At this time, the universal ball module 92 can correct the laminated glass to ensure that the laminated glass enters the subsequent process with the correct posture, thereby ensuring the production yield.

[0116] Specifically, at this time, the camera module 5 is used to detect the edge contour of the laminated glass to determine whether the posture of the laminated glass is correct, so as to cooperate with the universal ball module 92 to realize the adjustment of the laminated glass.

[0117] In this structure, the second frame 6 is configured as a double-layer structure, the lifting mechanism 8 is disposed on the lower layer 62, and the lifting mechanism 8 penetrates the upper layer 61, so that the lifting mechanism 8 can have a larger stroke to increase the lifting range of the laminated glass;

[0118] Specifically, after the camera module 5 detects that the laminated glass has defects, the laminated glass can be directly lifted by the lifting mechanism 8 until the laminated glass corresponds to the conveyor chain 3, and then the laminated glass with defects can be sent to the conveyor chain 3 by the universal ball module 92;

[0119] When the laminated glass has no defects, the universal ball module 92 sends the laminated glass into the hot pressing module 2 .

[0120] like Figures 7-9 As shown, the introduction mechanism 10 includes a second electric push rod 1011, a reversing motor 1012 and a third limit plate 1013, wherein the cylinder body of the second electric push rod 1011 is arranged on the first frame 1; the reversing motor 1012 is arranged at the end of the movable rod of the second electric push rod 1011, and the output shaft of the reversing motor 1012 is coaxial with the movable rod of the second electric push rod 1011; the third limit plate 1013 is arranged on the output shaft of the reversing motor 1012; the end of the first frame 1 facing the second frame 6 is provided with a guide groove 101, and the guide groove 101 extends to the end of the lower heating module 21;

[0121] As in the above structure, the lifting mechanism 8 drives the laminated glass to move to the height corresponding to the hot pressing module 2, and then the laminated glass is reversed by the rotating table 91, and then the laminated glass is sent into the hot pressing module 2 by the universal ball module 92; however, in this structure, the hot pressing module 2 needs to have a power element, such as a conveyor chain, so that after the laminated glass is separated from the universal ball module 92, it can continue to move toward the hot pressing module 2 until the entire laminated glass enters the hot pressing module 2;

[0122] In this solution, the introduction mechanism 10 is a power element. Specifically, before the laminated glass is transferred through the universal ball module 92, the third limit plate 1013 is always facing the second frame 6 to avoid interfering with the laminated glass. After that, the universal ball module 92 transports the laminated glass, and after the end of the laminated glass is separated from the universal ball module 92, the reversing motor 1012 will drive the third limit plate 1013 to rotate, so that the end of the third limit plate 1013 faces upward. After that, when the second electric push rod 1011 moves, the third limit plate 1013 will drive the laminated glass to move until the laminated glass completely enters the hot pressing module 2.

[0123] When the third limiting plate 1013 moves, it will slide and cooperate with the guide groove 101 to avoid interference problems.

[0124] like Figure 5 As shown, the first laser 12 is arranged on the lifting mechanism 8, and is used to measure the transparency of the laminated glass; the second laser 13 is arranged on the second frame 6, and is used to measure the bending shape of the laminated glass;

[0125] As in the above structure, the first laser 12 detects the laminated glass. After the laminated glass is stacked, if there is a quality defect in the middle glue layer, or if the unstacked glass is placed by mistake, it has a different light transmittance from the normal laminated glass. At this time, the first laser 12 detects the laminated glass, and according to the difference in the intensity of the reflected light, it can be determined whether the laminated glass is normal. If it is not normal, the process stops, which can avoid the problem of misprocessing, not only saving resources but also improving production efficiency.

[0126] The second laser 13 detects the bending shape of the laminated glass. After the laminated glass is placed on the supporting cable 75, the laminated glass will have a certain bending deformation due to its own weight. At this time, by relying on the two second lasers 13 to detect the distance from the laminated glass to the second lasers 13, it can be determined whether the deformation of the laminated glass is normal. If excessive bending or a small bending arc occurs, it means that there is a problem with the laminated glass. At this time, the laminated glass can be removed to avoid affecting the yield of the finished product.

[0127] In some embodiments, Fig.11 As shown, the hot pressing module 2 is not provided on one side of the carrier mechanism 7 of the laminating device, but a conveying roller 14 is provided. At this time, after the laminated glass is laminated, it is placed on the carrier mechanism 7 for position adjustment, and then lifted by the lifting mechanism 8, and then the laminated glass is reversed and slightly adjusted by the reversing mechanism 9, and then sent to the conveying roller 14, and the laminated glass is conveyed by the conveying roller 14;

[0128] Meanwhile, a hot pressing module 2 is disposed at the other end of the conveying roller 14 to perform a hot pressing preparation process on the laminated glass.

[0129] The application method of the laminated glass preparation device of the present invention comprises the following steps:

[0130] S1. Clean the glass, make sure there is no dirt on the glass surface, and lay film on the glass;

[0131] S2. Lay another layer of glass on the film to ensure that the two layers of glass are aligned, then cut the edges to remove excess film;

[0132] S3, the laminated glass is formed into a laminated glass, and then the laminated glass is placed on the supporting mechanism 7;

[0133] S4, detecting the bending shape of the laminated glass by the second laser 13 to ensure that the curvature is within a normal threshold;

[0134] S5. When the curvature of the laminated glass is within the normal threshold, the next step is executed; when the curvature of the laminated glass exceeds the normal threshold, the process stops;

[0135] S6, correcting the posture of the laminated glass by the carrying mechanism 7;

[0136] S7, detecting the transparency of the laminated glass by the first laser 12 to confirm that the laminated glass is correctly constituted;

[0137] S8, when the laminated glass is correctly constituted, the laminated glass is lifted by the lifting mechanism 8, and the direction of the laminated glass is adjusted by the reversing mechanism 9 so that the laminated glass corresponds to the first frame 1, and the next step is executed; when the laminated glass is incorrectly constituted, the lifting mechanism 8 does not act, and the process stops;

[0138] S9, the laminated glass is transferred to between the lower heating module 21 and the upper heating module 22 through the reversing mechanism 9;

[0139] S10, the lower heating module 21 and the upper heating module 22 are closed to perform heat pressing molding on the laminated glass.

[0140] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
