Description

Technical Field

[0001] This invention belongs to the field of sheet metal stacking and bundling technology, specifically relating to a glass magnesium sheet stacking and bundling device and method. Background Technology

[0002] Magnesium oxide (MgO) sheets are a new type of non-combustible decorative material made from a ternary system of magnesium oxide, magnesium chloride, and water through the addition of modifiers. After the MgO sheets are rolled, cured, dried, excess material is trimmed, and protective stickers are applied to the edges, they need to be stacked and bundled for easy transportation. To facilitate the transfer and loading of the stacked MgO sheets using forklifts or other tools, they are generally placed on wooden pallets. To prevent the strapping from damaging the MgO sheets during bundling, top corner protectors are typically installed on the longitudinal edges of the top surface of the stacked MgO sheets before longitudinal bundling with strapping, and vertical corner protectors are installed on the vertical edges of the stacked MgO sheets before transverse bundling with strapping.

[0003] Currently, the stacking of magnesium oxide (MgO) sheets mostly utilizes vacuum suction cups to adhere to the top surface of the sheets or clamping plates to hold the sheets around their perimeter before placing them on wooden pallets. For example, the gantry-type MgO sheet palletizing machine disclosed in CN210064515U uses a clamping plate device to pick up the sheets, and then stacks them under the drive of a horizontal, vertical, and lifting mechanism. However, using vacuum suction cups to adhere to the top surface of the MgO sheets is problematic because the suction area is very small relative to the surface of the MgO sheet, and the MgO sheet is soft, making it easy to tear around the suction cups. Similarly, clamping the sheets around their perimeter with clamping plates can easily damage them.

[0004] The bundling of the stacked magnesium oxide sheets is currently mainly done manually, which is labor-intensive and inefficient. Summary of the Invention

[0005] Purpose of the invention: The first purpose of the invention is to provide a magnesium oxide sheet stacking and bundling device with high stacking and bundling efficiency and the ability to avoid damage to the magnesium oxide sheet; the second purpose of the invention is to provide a magnesium oxide sheet stacking and bundling method.

[0006] Technical Solution: The present invention provides a glass magnesium oxide (MgO) plate stacking and bundling device, comprising a high-level conveyor belt arranged in a linear sequence, a stacking component, a front low-level conveyor belt, a vertical bundling machine, and a rear low-level conveyor belt; the high-level conveyor belt continuously transports single MgO plates to the stacking component; the stacking component includes a bearing assembly and transfer assemblies symmetrically arranged on both sides of the bearing assembly; the bearing assembly has a conveyor belt supported by several telescopic springs; the two transfer assemblies continuously receive single MgO plates transported by the high-level conveyor belt, and perform lateral positioning, stacking, and longitudinal correction on the single MgO plates to form stacked MgO plates; the several telescopic springs are configured to ensure that the position of the top MgO plate on the wooden pallet is always at a set height; the conveyor belt, when its height is consistent with that of the front low-level conveyor belt, carries the wooden pallet along with the stacked MgO plates. The flat plate is conveyed to the front low-position conveyor belt; symmetrically arranged on both sides of the front low-position conveyor belt are top corner protector placement components for placing top corner protectors on the longitudinal edges of the top surface of the laminated magnesium oxide flat plate; a vertical strapping machine is used to strap longitudinal plastic strips at the top corner protector positions of the laminated magnesium oxide flat plate, and the laminated magnesium oxide flat plate can span the front low-position conveyor belt and the rear low-position conveyor belt on the vertical strapping machine; symmetrically arranged on both sides of the rear low-position conveyor belt are vertical corner protector supply conveyor belts along their vertical direction, and symmetrically arranged on both sides of each vertical corner protector supply conveyor belt are vertical corner protector placement components, which are used to supply vertical corner protectors to the two vertical corner protector placement components on the corresponding side, and the vertical corner protector placement components are used to place vertical corner protectors at the corresponding vertical edges of the laminated magnesium oxide flat plate; a horizontal strapping machine for strapping transverse plastic strips to the laminated magnesium oxide flat plate is arranged across any one of the vertical corner protector supply conveyor belts.

[0007] Furthermore, several guide rods are installed in a linear array on both sides of the bottom surface of the conveyor belt. The guide rods are inserted into the center holes of each support leg in a clearance fit. The telescopic springs are sleeved on the guide rods, and the two ends of the telescopic springs abut against the bottom surface of the conveyor belt and the top surface of the support leg, respectively.

[0008] Furthermore, the transfer assembly includes a second bracket, the upper surface of which is provided with a support plate and a first rodless cylinder; the upper surface of the support plate has two upper vertical bars, forming a middle groove between the two upper vertical bars; a transverse bearing assembly is fixedly installed on the front surface of the support plate near the bearing assembly, the transverse bearing assembly including a transverse base and multiple unpowered rollers installed parallel to the transverse base; a longitudinal drive assembly capable of switching between high and low positions is provided in the middle groove, the longitudinal drive assembly including a longitudinal base and multiple powered rollers installed parallel to the longitudinal base; when the longitudinal drive assembly is in the high position, the upper generatrix of the powered rollers is higher than the upper generatrix of the unpowered rollers, and the two longitudinal drive assemblies convey the magnesium oxide plate forward until the leading edge of the magnesium oxide plate abuts against the stop at the end of the transverse base; when the longitudinal drive assembly is in the low position, the upper generatrix of the powered rollers is lower than the upper generatrix of the unpowered rollers, and the two transverse bearing assemblies support the magnesium oxide plate; the first rodless cylinders of the two transfer assemblies respectively drive the corresponding support plates away from the center line of the bearing assembly until the magnesium oxide plate falls onto the wooden pallet on the conveyor belt; or respectively drive the corresponding support plates closer to the bearing assembly to reset.

[0009] Furthermore, a lifting frame and a second rodless cylinder are provided on the rear surface of the support plate away from the load-bearing component. The second rodless cylinder is used to drive the lifting frame through the upper vertical bar and insert it into the bottom of the intermediate groove to lift the longitudinal drive assembly to a high position, or to drive the lifting frame out of the intermediate groove so that the longitudinal drive assembly falls to a low position by its own weight.

[0010] Furthermore, a correction kit is installed on the lower surface of the second support. The correction kit includes a correction plate and a second double-rod telescopic cylinder. The second double-rod telescopic cylinders of the two transfer components drive the corresponding correction plates to move towards each other to correct the alignment of the stacked glass magnesium flat plates.

[0011] Furthermore, the support plate and the correction plate are each equipped with a guiding mechanism.

[0012] Furthermore, the top corner protector placement component includes a third double-rod telescopic cylinder, a top corner protector support box with a long slot, and an L-shaped push rod capable of moving in a straight line. Several top corner protectors are stacked in the top corner protector support box with vertical blocks inserted into the long slot. The vertical bar of the L-shaped push rod is inserted into the long slot, and the L-shaped push rod is used to push the top corner protectors out of the top corner protector support box in sequence. The horizontal block portion of the pushed-out top corner protector rests on the top surface of the stacked glass magnesium oxide plate. The third double-rod telescopic cylinder is used to push the top corner protector so that the horizontal block of the top corner protector is completely resting on the top surface of the stacked glass magnesium oxide plate.

[0013] Furthermore, the vertical corner protector mounting component includes a turntable assembly mounted on a two-degree-of-freedom moving platform, capable of moving laterally and longitudinally. The turntable assembly has a horizontally positioned turntable and a turntable motor for driving the turntable to rotate. A flipping assembly is mounted on the turntable, which has a seventh rotating shaft horizontally rotatably mounted on the turntable using a seventh bearing and a flipping motor for driving the seventh rotating shaft to rotate. A suction cup mounting plate is fixedly mounted on the seventh rotating shaft, and a vacuum suction cup for picking up the vertical corner protector is mounted on the suction cup mounting plate.

[0014] Furthermore, the turntable assembly also includes a turntable bracket, on which the turntable is mounted using ball bearings; the turntable motor is mounted on the bottom surface of the turntable bracket, and the output end of the turntable motor passes through the turntable bracket and is fitted with a non-circular drive block, which is inserted into a non-circular groove on the bottom surface of the turntable.

[0015] The present invention provides a method for stacking and bundling magnesium oxide (MgO) flat plates, employing the aforementioned magnesium oxide (MgO) flat plate stacking and bundling device. The method includes the following steps:

[0016] (1) Place the wooden pallet on the conveyor belt;

[0017] (2) When the high-level conveyor belt starts, the two transfer components continuously receive the single glass magnesium plate conveyed by the high-level conveyor belt, and perform lateral limiting, stacking on the wooden pallet on the conveyor belt and longitudinal correction on the single glass magnesium plate to form a stacked glass magnesium plate; when the conveyor belt is at the same height as the front low-level conveyor belt, the wooden pallet along with the stacked glass magnesium plate is conveyed to the front low-level conveyor belt.

[0018] (3) The front low-position conveyor belt transports the stacked glass magnesium plate to the top corner protection placement component, and the top corner protection placement component places the top corner protection on the longitudinal edge of the top surface of the stacked glass magnesium plate.

[0019] (4) When the stacked magnesium oxide sheets with top corner protectors placed on both sides of the top surface pass through the vertical strapping machine, the vertical strapping machine straps longitudinal plastic strips at the top corner protector position of the stacked magnesium oxide sheets.

[0020] (5) When the longitudinally bundled stacked magnesium oxide sheets are moved to the horizontal bundling machine, the four vertical corner protectors are placed on the four vertical edges of the stacked magnesium oxide sheets. Then the horizontal bundling machine tightens the horizontal plastic strip around the vertical corner protectors to form a bidirectionally bundled stacked magnesium oxide sheets.

[0021] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages:

[0022] (1) The present invention realizes full automation of the process of stacking glass magnesium oxide plates, placing top corner protectors, longitudinal binding, vertical corner protector placement, and horizontal binding, which reduces the labor intensity of workers and improves the efficiency of stacking and binding glass magnesium oxide plates.

[0023] (2) The palletizing component is designed as a carrying component and a transfer component. The transfer component places the magnesium oxide sheets onto the carrying component. Compared with the traditional method of stacking magnesium oxide sheets by adsorbing the top surface of the sheets with vacuum suction cups or clamping the sides with clamping plates, this method can better avoid damage to the sheets. The carrying component uses the compressibility of a telescopic spring to automatically adjust the vertical position of the wooden pallet carrying the magnesium oxide sheets, facilitating the stacking of the sheets. After stacking, the bottom height of the wooden pallet carrying the sheets is consistent with the height of the downstream conveyor belt, facilitating the transport of the stacked sheets to the downstream conveyor belt.

[0055] like Figures 1 to 4 As shown, an embodiment of the present invention provides a glass magnesium flat plate stacking and strapping device, including a high-level conveyor belt 1, a stacking component 2, a top corner protector placement component 3, a front low-level conveyor belt 4, a vertical strapping machine 5, a rear low-level conveyor belt 6, a vertical corner protector placement component 7, a horizontal strapping machine 8, and a vertical corner protector supply conveyor belt 10.

[0056] The high-level conveyor belt 1, the palletizing component 2, the front low-level conveyor belt 4, the vertical strapping machine 5, and the rear low-level conveyor belt 6 are arranged in a linear sequence. Two top corner protector mounting components 3 are symmetrically arranged on both sides of the front low-level conveyor belt 4. Two vertical corner protector supply conveyor belts 10 are symmetrically arranged on both sides of the rear low-level conveyor belt 6 along the vertical direction of the rear low-level conveyor belt 6. Vertical corner protector mounting components 7 are symmetrically arranged on both sides of each vertical corner protector supply conveyor belt 10. The horizontal strapping machine 8 is arranged across any one of the vertical corner protector supply conveyor belts 10.

[0057] like Figure 5As shown, the palletizing component 2 includes a carrying component 22 and transfer components 23 symmetrically arranged on both sides of the carrying component 22. The two transfer components 23 continuously receive single pieces of glass magnesium flat plates 0 conveyed by the high-level conveyor belt 1, and perform lateral limiting, stacking on the wooden pallet 91 (not shown in the figure) on the carrying component 22 and longitudinal correction to form stacked glass magnesium flat plates.

[0058] like Figure 6 As shown, the supporting component 22 includes a conveyor belt 221, guide rods 222, telescopic springs 223, and support legs 224. Several guide rods 222 are linearly arrayed on both sides of the bottom surface of the conveyor belt 221. The guide rods 222 are inserted into the center holes of each support leg 224 in a clearance fit. The telescopic springs 223 are sleeved on the guide rods 222, and the two ends of the telescopic springs 223 abut against the bottom surface of the conveyor belt 221 and the top surface of the support leg 224, respectively.

[0059] When a single piece of magnesium oxide sheet 0 is placed on the wooden pallet 91 on the support component 22, the telescopic spring 223 is compressed under the weight of the magnesium oxide sheet, causing the conveyor belt 221 to move downward, ensuring that the top piece of magnesium oxide sheet on the wooden pallet 91 is always at the set height. When the conveyor belt 221 is at the same height as the front low-position conveyor belt 4, the conveyor belt 221 transports the wooden pallet 91 along with the stacked magnesium oxide sheets onto the front low-position conveyor belt 4.

[0060] like Figures 7 to 9 As shown, the transfer assembly 23 includes a second bracket 230, a support plate 231, a correction kit 232, a longitudinal drive kit 233, a lateral load-bearing kit 234, a lifting frame 235, a second rodless cylinder 236, a first rodless cylinder 239, and a first guide mechanism. The first guide mechanism includes a first linear bearing 237 and a first guide rod 238.

[0061] The first rodless cylinder 239 is installed at the center of the upper surface of the second bracket 230. Four first linear bearings 237 are arranged in a linear array on the upper surface of the second bracket 230 and located on both sides of the first rodless cylinder 239. The first guide rod 238 is fitted into the first linear bearing 237. The lower vertical strip 231.7 of the support plate 231 is fixedly connected to the flange end of the first guide rod 238 and also fixedly connected to the slider of the first rodless cylinder 239. The first rodless cylinder 239 can drive the support plate 231 to move back and forth.

[0062] The upper surface of the support plate 231 has two vertical strips 231.5, forming a central groove 231.2, a front surface 231.1 near the support assembly 22, and a rear surface 231.4 away from the support assembly 22. A notch 231.6 for mounting the first rodless cylinder 239 is provided on the rear surface 231.4. The longitudinal drive assembly 233 is placed in the central groove 231.2, and the transverse support assembly 234 is fixedly mounted on the front surface 231.1.

[0063] like Figure 11 As shown, the longitudinal drive kit 233 includes a longitudinal base 2331 and multiple driven rollers 2332 mounted in parallel on the longitudinal base 2331. A ramp 2331.1 is machined on one side of the bottom of the longitudinal base 2331.

[0064] like Figure 12 As shown, the transverse support assembly 234 includes a transverse base 2342 and multiple unpowered rollers 2341 mounted in parallel on the transverse base 2342. A stop block 2342.1 is provided at the end of the transverse base 2342.

[0065] The lifting frame 235 has a horizontal bar and vertical bars connected to both ends of the horizontal bar. The front end of the vertical bar of the lifting frame 235 is machined with a slope, the slope of which is the same as the slope of the slope 2331.1 at the bottom of the longitudinal base 2331. Two second rodless cylinders 236 are mounted on the rear surface 231.4. The two lifting frames 235 are respectively inserted into the rectangular holes 231.3 of the upper vertical bar 231.5. The horizontal bars of the two lifting frames 235 are respectively fixedly connected to the sliders of the two second rodless cylinders 236.

[0066] When the slider of the second rodless cylinder 236 approaches the longitudinal drive assembly 233, the two vertical rods of the drive lifting frame 235 move in the rectangular hole 231.3 of the upper vertical bar 231.5, lifting the longitudinal drive assembly 233 to a high position, so that the upper generatrix of the driven roller 2332 is higher than the upper generatrix of the undriven roller 2341. At this time, the two longitudinal drive assemblies 233 can transport the glass magnesium plate 0 forward until the leading edge of the glass magnesium plate 0 abuts against the stop block 2342.1. When the slider of the second rodless cylinder 236 moves away from the longitudinal drive assembly 233, the two vertical rods of the drive lifting frame 235 are pulled out from the rectangular hole 231.3 of the upper vertical bar 231.5, and the longitudinal drive assembly 233 moves down to a low position by its own gravity, so that the upper generatrix of the driven roller 2332 is lower than the upper generatrix of the undriven roller 2341. At this time, the two transverse bearing assemblies 234 bear the glass magnesium plate 0. Furthermore, the first rodless cylinders 239 of the two transfer components 23 respectively drive the corresponding support plates 231 away from the center line of the carrier component 22 until the glass magnesium plate 0 falls onto the wooden pallet 91 on the conveyor belt 221; or respectively drive the corresponding support plates 231 closer to the carrier component 22 to reset.

[0067] like Figure 10 As shown, the correction kit 232 is installed on the lower surface of the second bracket 230 and includes a correction plate 2321, a second double-rod telescopic cylinder 2322 and a second guide mechanism. The second guide mechanism includes a third linear bearing 2323 and a third guide rod 2324.

[0068] The second double-rod telescopic cylinder 2322 is installed at the middle position of the lower surface of the second bracket 230. Four third linear bearings 2323 are installed in a linear array on the lower surface of the second bracket 230 and located on both sides of the second double-rod telescopic cylinder 2322. The third guide rod 2324 is fitted into the third linear bearing 2323. The correction plate 2321 is fixedly connected to the flange end of the third guide rod 2324 and simultaneously fixedly connected to the end of the piston rod of the second double-rod telescopic cylinder 2322. The second double-rod telescopic cylinders 2322 of the two intermediate components 23 drive the corresponding correction plates 2321 to move towards each other to correct the stacked glass magnesium oxide plates.

[0069] like Figures 13 to 15 As shown, the top corner protector mounting component 3 includes a third bracket 31, a third double-rod telescopic cylinder 32, a top corner protector bearing box 33, an L-shaped push rod 34, a third motor 35, a third lead screw 36, a third nut 37, a third slider 38, and a third guide rail 39.

[0070] The third guide rail 39 is installed in the middle of the top surface of the third bracket 31. The third lead screw 36 is installed in the middle of the top surface of the third bracket 31 via a bearing seat and is located directly above the third guide rail 39. The third motor 35 is installed at one end of the top surface of the third bracket 31. The output shaft of the third motor 35 is connected to the third lead screw 36 via a coupling. The third slider 38 is installed on the third guide rail 39. The third nut 37 is installed on the third lead screw 36. The bottom surface of the third nut 37 is fixedly connected to the top surface of the third slider 38.

[0071] The top surface of the top corner protector support box 33 is machined with a long slot 33.1 that runs through both the left and right ends. The L-shaped top corner protectors 92 are composed of horizontal blocks and vertical blocks that are perpendicularly connected together. Several vertical blocks of the top corner protectors 92 are inserted into the long slot 33.1, thus stacking the top corner protectors 92 in the top corner protector support box 33. The top corner protector support box 33 is mounted parallel to the third guide rail 39 on the top surface of the third bracket 31. The L-shaped push rod 34 is composed of horizontal blocks and vertical bars that are perpendicularly connected together. The horizontal blocks of the L-shaped push rod 34 are mounted on the third nut 37, and the vertical bars of the L-shaped push rod 34 are inserted into the long slot 33.1. The third motor 35 drives the L-shaped push rod 34 to move along the third guide rail 39, thereby moving the vertical bars of the L-shaped push rod 34 in the long slot 33.1, pushing the top corner protectors 92 out of the top corner protector support box 33 in sequence.

[0072] The third double-rod telescopic cylinder 32 is installed at one end of the top surface of the third bracket 31 and is located behind the top corner support box 33. When the top corner 92 is pushed out of the top corner support box 33, the horizontal block of the top corner 92 rests on the top surface of the stacked glass magnesium plate. At this time, the piston rod of the third double-rod telescopic cylinder 32 extends and pushes the top corner 92 so that the horizontal block of the top corner 92 rests completely on the top surface of the stacked glass magnesium plate, thus realizing the placement of the top corner 92 on the top surface of the stacked glass magnesium plate.

[0073] like Figure 16 As shown, the vertical corner protector mounting component 7 includes a longitudinal moving assembly 71, a transverse moving assembly 72, a turntable assembly 73, and a tilting assembly 74. The drive plate of the transverse moving assembly 72 and the drive plate of the longitudinal moving assembly 71 are fixedly connected together, thereby mounting the transverse moving assembly 72 on the longitudinal moving assembly 71 to form a two-degree-of-freedom moving platform. The turntable assembly 73 is mounted on the transverse moving assembly 72, and the tilting assembly 74 is mounted in the turntable assembly 73.

[0074] like Figure 17 As shown, the longitudinal movement assembly 71 includes a seventh bracket 711, a seventh guide rail 712, a seventh slider 713, a drive plate 714, a seventh lead screw 715, and a seventh motor 716. The seventh lead screw 715 is mounted on the top surface of the seventh bracket 711 at the middle position via a bearing seat. Two seventh guide rails 712 are mounted on the top surface of the seventh bracket 711 with the seventh lead screw 715 as the center of symmetry. The seventh motor 716 is mounted at one end of the top surface of the seventh bracket 711 at the middle position. The output shaft of the seventh motor 716 is connected to the seventh lead screw 715 via a coupling. The seventh slider 713 is fitted on the seventh guide rail 712. A seventh nut (not shown in the figure) is fitted on the seventh lead screw 715. The drive plate 714 is mounted on the seventh guide rail 712 via the seventh slider 713 and is fixedly connected to the seventh nut.

[0075] The lateral movement component 72 has a similar structure to the longitudinal movement component 71, and will not be described in detail here.

[0076] like Figure 18 and Figure 19 As shown, the turntable assembly 73 includes a turntable bracket 731, a turntable 732, a turntable motor 733, a shaped drive block 734, and a ball bearing 735. A through hole is machined at the center of the top plate of the turntable bracket 731, and a groove is machined around the through hole. A shaped groove is machined at the center of the bottom surface of the turntable 732, and a corresponding groove is machined around the outer edge of the shaped groove in the turntable bracket 731. The ball bearing 735 is installed in the groove of the turntable bracket 731, and the groove of the turntable 732 engages with the ball bearing 735, thereby rotatably mounting the turntable 732 on the top plate of the turntable bracket 731.

[0077] A turntable motor 733 is mounted on the bottom surface of the top plate of the turntable bracket 731. Its output shaft passes through a through hole at the center of the top plate of the turntable bracket 731. A non-circular drive block 734 is mounted on the output shaft of the turntable motor 733. The shape of the non-circular drive block 734 matches the shape of the non-circular groove at the center of the turntable 732. The non-circular drive block 734 is inserted into the non-circular groove at the center of the bottom surface of the turntable 732. When the output shaft of the turntable motor 733 rotates, it drives the turntable 732 to rotate on the turntable bracket 731.

[0078] like Figure 20 and Figure 21 As shown, the flipping assembly 74 includes a seventh bearing 741, a suction cup mounting plate 742, a vacuum suction cup 743, a flipping motor 744, a synchronous pulley 745, a synchronous belt 746, and a seventh rotating shaft 747.

[0079] Two seventh bearings 741 are mounted on a turntable 732. A suction cup mounting plate 742 is rotatably mounted between the two seventh bearings 741 via a seventh rotating shaft 747. A tilting motor 744 is mounted on the turntable 732 via a motor mounting plate. A synchronous pulley 745 is mounted on the output shaft of the tilting motor 744, and a synchronous pulley 745 is also mounted on the seventh rotating shaft 747. The synchronous pulleys 745 on the output shaft of the tilting motor 744 and the synchronous pulleys 745 on the seventh rotating shaft 747 are connected by a synchronous belt 746. The tilting motor 744 drives the suction cup mounting plate 742 and the vacuum suction cup 743 mounted on it to tilt around the seventh rotating shaft 747.

[0080] This invention also provides a method for stacking and bundling magnesium oxide sheets, comprising the following steps:

[0081] (1) Place the wooden pallet 91 on the conveyor belt 221, place several top corner protectors 92 in the top corner protector carrier box 33, and place several vertical corner protectors 94 on the vertical corner protector supply conveyor belt 10.

[0082] (2) Stacking of glass magnesium plates

[0083] (2-1) When the high-level conveyor belt 1 is started, the second rodless cylinder 236 of the two transfer components 23 drives the lifting frame 235 to lift the longitudinal drive kit 233 to a high position, so that the upper generatrix of the powered roller 2332 is higher than the upper generatrix of the unpowered roller 2341. The longitudinal drive kit 233 of the two transfer components 23 is started, and the single piece of glass magnesium plate 0 conveyed from the upstream continues to be conveyed forward until the leading edge of the glass magnesium plate 0 abuts against the stop block 2342.1.

[0084] (2-2) The second rodless cylinder 236 of the two transfer components 23 drives the lifting frame 235 to retract, and the longitudinal drive kit 233 moves down to a low position by its own gravity, so that the upper generatrix of the powered roller 2332 is lower than the upper generatrix of the unpowered roller 2341. At this time, the unpowered roller 2341 of the two transverse bearing kits 234 carries the glass magnesium plate 0.

[0085] (2-3) The first rodless cylinder 239 of the two transfer components 23 drives the support plate 231 away from the center line of the bearing component 22 until the glass magnesium plate 0 carried by the unpowered roller 2341 of the two transverse bearing components 234 falls on the bearing component 22. Under the action of the gravity of the glass magnesium plate, the extension spring 223 of the bearing component 22 compresses the thickness of one glass magnesium plate, so that the position of the top glass magnesium plate of the stacked glass magnesium plates is always at the set height.

[0086] (2-4) The piston rods of the second double-rod telescopic cylinders 2322 of the two intermediate components 23 extend simultaneously, driving the correction plates 2321 to move towards each other, and correcting the stacked glass magnesium flat plates.

[0087] (2-5) When the height of the conveyor belt 221 is consistent with that of the front low-position conveyor belt 4, the wooden pallet 91 together with the stacked glass magnesium plate is conveyed to the front low-position conveyor belt 4.

[0088] (3) Install top corner protectors 92 on the longitudinal edge of the top surface of the laminated glass magnesium plate.

[0089] (3-1) The third motor 35 drives the L-shaped push rod 34 to move along the third guide rail 39, thereby driving the vertical bar of the L-shaped push rod 34 to move in the long groove 33.1 of the top corner support box 33, pushing the foremost top corner 92 out of the top corner support box 33, so that the horizontal block part of the top corner 92 rests on the top surface of the stacked glass magnesium plate.

[0090] (3-2) The piston rod of the third double-rod telescopic cylinder 32 extends and pushes the top corner protector 92 so that the horizontal block of the top corner protector 92 is completely placed on the top surface of the stacked glass magnesium plate, thus realizing the placement of the top corner protector 92 on the longitudinal edge of the stacked glass magnesium plate.

[0091] (4) The laminated glass magnesium plate is longitudinally bundled.

[0092] When the stacked magnesium oxide sheets with top corner protectors 92 placed on the longitudinal edge of the top surface pass through the vertical strapping machine 5, the vertical strapping machine 5 straps longitudinal plastic strips 93 at the top corner protector position, thus longitudinally strapping the stacked magnesium oxide sheets with top corner protectors 92 placed on both sides of the top surface.

[0093] (5) After longitudinally binding, the stacked glass magnesium oxide plates are placed with vertical corner protection and then horizontally bound.

[0094] (5-1) The turntable assembly 73 and the tilting assembly 74 mounted thereon move under the drive of the longitudinal moving assembly 71 and the transverse moving assembly 72, and move closer to the vertical corner protector supply conveyor belt 10. Under the drive of the turntable assembly 73, the tilting assembly 74 adjusts the orientation of the suction cup mounting plate 742 so that the orientation of the vacuum suction cup 743 mounted on the suction cup mounting plate 742 matches the vertical corner protector 94 placed on the vertical corner protector supply conveyor belt 10.

[0095] (5-2) The flip motor 744 drives the suction cup mounting plate 742 and the vacuum suction cup 743 mounted on it to rotate 90 degrees around the seventh rotating shaft 747, so that the suction cup mounting plate 742 and the vacuum suction cup 743 mounted on it are adjusted from a vertical state to a horizontal state. The vacuum suction cup 743 is activated and adsorbs the vertical corner protector 94. The flip motor 744 then drives the suction cup mounting plate 742 and the vacuum suction cup 743 mounted on it to rotate 90 degrees in the opposite direction around the seventh rotating shaft 747, so that the suction cup mounting plate 742 and the vacuum suction cup 743 mounted on it are adjusted from a horizontal state to a vertical state.

[0096] (5-3) Driven by the turntable assembly 73, the flipping assembly 74 adjusts the orientation of the suction cup mounting plate 742 so that the orientation of the vertical corner protector 94 adsorbed by the vacuum suction cup 743 matches the orientation of the four vertical edges of the laminated glass magnesium plate. Driven by the longitudinal moving assembly 71 and the transverse moving assembly 72, the vertical corner protector 94 moves closer to the four vertical edges of the laminated glass magnesium plate until they fit together.

[0097] (5-4) The horizontal strapping machine 8 straps the horizontal plastic strip 95 around the vertical corner protector 94, and performs horizontal strapping on the stacked glass magnesium flat sheets after longitudinal strapping, forming a two-way strapped stacked glass magnesium flat sheet, which facilitates the transportation of glass magnesium flat sheets.
