Description

Technical Field

[0001] The present invention relates to the field of plate sorting and stacking, and in particular to a plate sorting and stacking machine and a plate sorting and stacking method. Background Art

[0002] During the sheet metal processing process, a sheet metal sorting and stacking machine is required to place and remove individual sheets from the three-dimensional racks. Traditional sheet metal sorting and stacking machines typically consist of a frame with running wheels on both sides, a lifting mechanism attached to the frame, and a sheet metal handling mechanism connected to the lifting mechanism. This mechanism typically consists of a frame with a sheet metal conveying mechanism at the bottom and a suction cup mechanism at the top.

[0003] Traditional plate sorting and stacking machines have the following shortcomings when used: they are unable to take out multiple plates from different layers of the three-dimensional shelf and place the plates side by side on the plate picking and placing mechanism; they are unable to align the plates and simultaneously transport the aligned plates placed side by side into the three-dimensional shelf. Summary of the Invention

[0004] Based on this, a plate sorting and stacking machine is provided. The plate sorting and stacking machine can take out multiple plates from different layers of a three-dimensional shelf and place each plate side by side on a plate picking and placing mechanism, align each plate, and simultaneously transport multiple plates placed side by side thereafter into the three-dimensional shelf.

[0005] To achieve the above object, the present invention adopts the following technical solutions: The lifting mechanism is a lifting mechanism that lifts up and down of upper and lower frames, and the lifting mechanism is a lifting mechanism that lifts up and down frames is installed. The base is provided with a gear rack, and the base is provided with a gear rack. The gear rack is meshed with the bracket rack and the base rack respectively. When the slide assembly moves, the gear rack rotates under the drive of the base rack, and then drives the telescopic movable bracket to move through the cooperation of the gear rack and the bracket rack. The two ends of the base are respectively provided with a support frame, and each support frame is provided with a baffle assembly, and the baffle assembly includes a baffle cylinder, a driving shaft, a driving block arranged on the driving shaft and a plurality of baffles arranged on the driving shaft. The driving shaft is rotated and cooperates with the support frame. The main body of the baffle cylinder is hinged with the support frame, and the piston rod of the baffle cylinder is hinged with the driving block, and the driving block is driven to move by the piston rod of the baffle cylinder, thereby prompting the driving shaft to rotate, thereby driving each baffle to rotate.

[0006] In one embodiment, a transverse movement assembly is provided inside the bottom frame, and the fork assembly is connected to the transverse movement assembly. The transverse movement assembly is used to adjust the spacing between the fork assemblies. When the frame moves along the X direction, the distance between two adjacent fork assemblies is changed to adapt to the size requirements of the plate to be transported.

[0007] In one embodiment, a set of fork assemblies is used to transport the sheet material in a first direction so that the sheet material enters a first storage position on the rack, and at the same time, a second set of fork assemblies is used to transport the sheet material in a second direction so that the sheet material enters a second storage position on the rack, the first direction being different from the second direction.

[0008] In one embodiment, when the bottom frame is rising or falling, the fork assembly moves the plate placed thereon in the Y direction.

[0009] In one embodiment, the first column and the second column are both provided with a vertically extending anti-fall plate, and a plurality of slots are provided on the anti-fall plate from top to bottom. A latch mechanism is provided at each end of the bottom frame, and the latch mechanism includes a latch driving mechanism and a latch. The latch driving mechanism is used to drive the latch to extend and retract so that the latch is extended and inserted into the corresponding slot. The number of latches provided on the latch mechanism is at least 2, and the latches are arranged from top to bottom.

[0010] In one embodiment, the latch driving mechanism drives each latch to move simultaneously, so that at least one latch is inserted into the corresponding slot.

[0011] In one embodiment, the traveling wheel is arranged on a traveling wheel bracket, an extension frame extending along the Y direction is arranged at one end of the traveling wheel bracket, and plate detection sensors are respectively arranged at both ends of the extension frame.

[0012] In one embodiment, a camera is provided on the top of one end of the bottom frame, and the height of the camera is higher than each fork assembly.

[0013] A plate sorting and stacking method adopts the plate sorting and stacking machine, firstly, the plate sorting and stacking machine places the cut plates of different sizes into a three-dimensional shelf, and each storage position in the shelf only places one plate. Then, the plate sorting and stacking machine sorts the plates in the three-dimensional shelf according to demand, so that each plate is taken out from the original storage position and put back into the new storage position.

[0014] A plate sorting and stacking method adopts the plate sorting and stacking machine described above, takes out multiple plates from a three-dimensional shelf by means of multiple fork assemblies, and while the frame moves along the X direction, transports each plate simultaneously in the same direction until each plate abuts against a corresponding baffle, so that the positions of each plate are aligned; then, the baffle rotates from a vertical state to an inclined state, and then, each plate is transported to a storage position in the three-dimensional shelf.

[0015] The beneficial effects of this application are: 1. This application utilizes multiple fork assemblies, each capable of picking up different sheets. This allows multiple sheets to be retrieved from different layers of a three-dimensional shelf and placed side by side on a sheet placement mechanism. A second type of synchronous belt then moves the sheets in the same direction until they rest against corresponding baffles, aligning them. The fork assemblies then simultaneously transport the aligned, side-by-side sheets into the three-dimensional shelf.

[0016] 2. This application includes a transverse movement assembly for adjusting the spacing between the fork assemblies. During X-axis movement of the frame, the distance between adjacent fork assemblies is varied to accommodate the size of the plates being transported. Adjusting the distance between the fork assemblies during X-axis movement saves time and improves efficiency. Furthermore, the adjustable distance between the fork assemblies allows for precise picking and transport of smaller plates while also enabling reliable picking and transport of larger plates.

[0017] 3. A set of fork assemblies is used to transport the plate in a first direction so that the plate enters the first storage position of the shelf. At the same time, a second set of fork assemblies is used to transport the plate in a second direction so that the plate enters the second storage position of the shelf. The first direction is different from the second direction, which is conducive to transporting multiple plates in different directions at the same time to improve the sorting and stacking efficiency.

[0018] 4. In this application, the fork assembly can also move the plates placed on the bottom frame in the Y direction during the bottom frame's ascent or descent. This is also beneficial for improving the efficiency of plate sorting and stacking.

[0019] 5. This application is equipped with a latch and an anti-fall plate. The latch extends and inserts into the corresponding slot, which can prevent the bottom frame and the fork assembly on it from falling. In addition, the latch mechanism of this application is equipped with at least two latches, and the latches are arranged from top to bottom, which helps to ensure that at least one latch can be smoothly inserted into the slot.

[0020] 6. The plate detection sensor installed on the extension frame is used to detect whether there are plates placed incorrectly on the three-dimensional shelf. This may cause the fork assembly to collide with the plate during the lifting process. If the plate is not placed correctly, the plate detection sensor will generate a signal, which will trigger the alarm. At this time, the fork assembly will not lift or lower.

[0021] 7. A camera is installed on the top of one end of the bottom frame, which can monitor the operating status of each fork assembly and the plates thereon.

[0022] 8. Since the present application is provided with multiple fork assemblies, the distance between the fork assemblies is adjustable, and the conveying directions of the fork assemblies are forward and reverse, the plate sorting stacker of the present application can quickly move the plates in the three-dimensional shelves, which is conducive to the rapid sorting of the plates.

[0043] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0044] like Figure 1 and Figure 2 As shown, the first embodiment of the present application provides a plate sorting and stacking machine, which includes a frame 100 and a lifting mechanism 502 arranged on the frame 100. The frame 100 includes an upper beam 101, a first column 102 and a second column 103 located at both ends of the upper beam 101, and a lower beam 104 connected to the first column 102 and the second column 103 respectively. The two sides of the lower beam 104 are respectively provided with running wheels and a running wheel driving mechanism 501. The running wheels are used to cause the frame 100 to move along the X direction. Figures 3 to 8 As shown, the bottom frame 400 is provided above the lower crossbeam 104 and is connected to the lifting mechanism 502. The bottom frame 400 is driven by the lifting mechanism 502 to rise or fall. A plurality of fork assemblies 200 are arranged side by side and spaced apart on the bottom frame 400. The conveying direction of the fork assembly 200 is the Y direction, and the X direction is perpendicular to the Y direction. The fork assembly 200 includes a base 201, and a first guide rail 202 is provided on the base 201. The first guide rail 202 is provided with a first slider assembly 203, and the first slider assembly 203 is provided with a slide assembly 204. The base 201 is also provided with a first type of synchronous belt 205 and a first type of synchronous belt driving assembly that drives the first type of synchronous belt 205 to move. The slide assembly 204 is connected to the first type of synchronous belt 205, and a second slider assembly 206 is provided at the top of the slide assembly 204. The second slider assembly 206 is slidably matched with the second guide rail 207. The second guide rail 207 is provided inside the telescopic movable bracket 208 and is connected to the telescopic movable bracket 208. The telescopic movable bracket 20 8 is provided with a bracket rack 2081 at the bottom end of one side, and a second type of synchronous belt 209 is also provided on the telescopic movable bracket 208. The second type of synchronous belt 209 is used to convey the plate, and also includes a second type of synchronous belt driving component for driving the second type of synchronous belt 209 to move. A gear 210 is provided on the slide assembly 204, and a base rack 2011 is provided on the base 201. The gear 210 is respectively engaged with the bracket rack 2081 and the base rack 2011. When the slide assembly 204 moves, the gear 210 rotates under the drive of the base rack 2011, and then the telescopic movable bracket 208 is driven to move by the cooperation of the gear 210 and the bracket rack 2081. Support frames 220 are respectively provided at both ends of the base 201, and each support frame 220 is provided with a baffle assembly, such as Figure 12As shown, the baffle assembly includes a baffle cylinder 221, a drive shaft 222, a drive block 223 arranged on the drive shaft 222, and a plurality of baffles 224 arranged on the drive shaft 222. The drive shaft 222 is rotatably coordinated with the support frame 220. The main body of the baffle cylinder 221 is hinged to the support frame 220. The piston rod of the baffle cylinder 221 is hinged to the drive block 223 through a cylinder fisheye joint 225 and a bolt. The drive block 223 is driven to move by the piston rod of the baffle cylinder 221, thereby causing the drive shaft 222 to rotate, thereby driving each baffle 224 to rotate.

[0045] Specifically, the lifting mechanism 502 can adopt the lifting mechanism 502 of the existing technology, for example, including a motor and a wire rope assembly driven by the motor. The lifting and lowering of the base frame 400 and the various fork assemblies 200 on the base frame 400 are achieved by the wire rope assembly. When it is necessary to take out the plate, the telescopic movable bracket 208 of the fork assembly 200 is extended and positioned under the plate. Then, the lifting mechanism 502 rises a short distance so that the plate is supported by the second type of synchronous belt 209 on the telescopic movable bracket 208. Then, the telescopic movable bracket 208 is retracted and reset. In this way, a plate can be taken out. When it is necessary to transport the plate into the three-dimensional shelf, the telescopic movable bracket 208 is extended, and then the telescopic movable bracket 208 is lowered so that the plate on the telescopic movable bracket 208 is supported by the three-dimensional shelf. Then, the telescopic movable bracket 208 is retracted and reset.

[0046] It is understood that each layer of the three-dimensional shelf structure may include a plurality of support rods placed side by side and arranged at intervals, and the gaps between the support rods can be used for the telescopic movable bracket 208 to pass through.

[0047] Specifically, when the telescopic movable bracket 208 needs to extend outward to pick up a sheet, the baffle 224 rotates to an inclined position, allowing the sheet on the telescopic movable bracket 208 to pass smoothly through the baffle 224. When the sheet is located inside the baffle 224, the baffle 224 rotates to a vertical position, preventing the sheet from passing through the baffle 224. When the second-type synchronous belt moves, the sheet moves with the second-type synchronous belt and abuts against the baffle 224. This allows the position of the sheet to be adjusted, ensuring that the position of the sheet on each fork assembly 200 is consistent.

[0048] Specifically, when plates need to be removed from different layers, the lifting mechanism 502 first transports each fork assembly 200 to the first target layer of the three-dimensional rack. A plate is removed from the first target layer, supported by one or two fork assemblies 200. Subsequently, the lifting mechanism 502 transports each fork assembly 200 to the second target layer, where a plate is removed. This plate is supported by one or two of the remaining idle fork assemblies 200. In this manner, multiple plates can be removed from different layers, each supported by a different fork assembly 200. After the plates have been removed, the fork assemblies 200 transport them until they abut against their corresponding baffles 224, thereby aligning them. The aligned plates are then transported together to their corresponding layers of the three-dimensional rack.

[0049] Specifically, such as Figure 9 As shown, the above-mentioned slide assembly 204 includes a synchronous belt pressure plate 2041, an intermediate frame 2042 connected to the synchronous belt pressure plate 2041, and two side frames 2043 connected to the intermediate frame 2042 and arranged at intervals, and the gear 210 is arranged on the side frames 2043.

[0050] Specifically, the telescopic movable bracket 208 passes through the gap between two adjacent baffles 224, and the baffles 224 will not affect the movement of the telescopic movable bracket 208.

[0051] In one embodiment, if Figure 13 As shown, the drive shaft 222 is provided with a guide wheel 226 for supporting and guiding the telescopic movable bracket 208, and switch brackets are vertically provided at both ends of the base 201. Each switch bracket is provided with a proximity switch 234, and a strip groove 235 is provided at both ends of the telescopic movable bracket 208. The strip groove 235 corresponds to the position of the proximity switch 234.

[0052] Specifically, the proximity switch 234 is used to detect whether the telescopic movable bracket 208 has retracted from its extended position to its initial position. In its initial position, the telescopic movable bracket 208 is positioned above the base 201, with the carriage assembly 204 positioned in the middle of the telescopic movable bracket 208. Both ends of the telescopic movable bracket 208 are supported by guide wheels 226.

[0053] Specifically, a proximity switch 234 may be provided at a middle position of the base 201 for detecting the position of the carriage assembly 204 .

[0054] In one embodiment, if Figure 7 As shown, a plurality of photoelectric sensors 227 may be provided on the fork assembly 200 for detecting the position of the plate.

[0055] In one embodiment, if Figures 5 to 7 As shown, in the same fork assembly 200, the number of the first guide rails 202 is two, and the two first guide rails 202 are arranged at intervals. The number of the first slider assemblies 203 is two groups, and the two groups of first slider assemblies 203 respectively correspond to the two first guide rails 202. The number of the second slider assemblies 206 is two groups, and the number of the second guide rails 207 is two, and the two second guide rails 207 are arranged at intervals. The two groups of second slider assemblies 206 respectively correspond to the two second guide rails 207. The telescopic movable bracket 208 The number is 2, and the two telescopic movable brackets 208 are arranged at intervals. The two telescopic movable brackets 208 correspond to and are connected to the two second guide rails 207 one by one. Two gears 210 are arranged at intervals on the slide assembly 204, and the two gears 210 are respectively arranged corresponding to the two telescopic movable brackets 208. Each telescopic movable bracket 208 is provided with a bracket rack 2081. The number of base racks 2011 on the base 201 is 2, and each gear 210 is engaged with the corresponding bracket rack 2081 and the base rack 2011.

[0056] Specifically, the presence of two telescopic movable supports 208 within the same fork assembly 200 facilitates good support for the plates, making plate transport more stable and reliable. The two telescopic movable supports 208 are spaced apart, leaving space between them for mounting other components. This effectively utilizes the space and makes the overall device compact.

[0057] Specifically, a wear-resistant lining plate fixed to the top of the telescopic movable bracket 208 may be further provided between the second type synchronous belt and the top of the telescopic movable bracket 208 .

[0058] In one embodiment, Figure 6 and Figure 7As shown, the first type of synchronous belt drive assembly includes a first motor 211, a first synchronous pulley 212, and a second synchronous pulley 213, which are arranged on the base 201. The first synchronous pulley 212 is connected to the first motor 211, and the second synchronous pulley 213 is arranged at both ends of the base 201 with the first synchronous pulley 212 spaced apart. The first type of synchronous belt 205 is wound between the first synchronous pulley 212 and the second synchronous pulley 213. The first motor 211 drives the first synchronous pulley 212 to rotate, thereby driving the first type of synchronous belt 205 to move. The second type of synchronous belt drive assembly includes a second motor 214, a transmission synchronous wheel assembly 215 and a rotating shaft 216. The second motor 214 is arranged on the base 201, the transmission synchronous wheel assembly 215 is arranged on the base 201 and connected to the second motor 214, the rotating shaft 216 is arranged on the base 201 and connected to the transmission synchronous wheel assembly 215, and the outer sides of both ends of each first guide rail 202 are provided with base synchronous wheels 217 installed on the base 201. The rotating shaft 216 is connected to two of the base synchronous wheels 217. Both ends of each telescopic movable bracket 208 are provided with bracket synchronous wheels 218. Auxiliary synchronous wheels 219 are provided on both sides of each gear 210 on the slide assembly 204. A second type of synchronous belt 209 is wound between the two base synchronous wheels 217, the two auxiliary synchronous wheels 219 and the two bracket synchronous wheels 218 located on the same side. The second motor 214 drives the rotating shaft 216 to rotate through the transmission synchronous wheel assembly 215, thereby driving the second type synchronous belt 209 to move.

[0059] In one embodiment, Figure 4 As shown, a transverse movement assembly is provided inside the bottom frame 400 , and the fork assembly 200 is connected to the transverse movement assembly, and the transverse movement assembly is used to adjust the distance between the fork assemblies 200 .

[0060] Specifically, the transverse shift assembly can have various implementations. For example, the transverse shift assembly includes a transverse shift cylinder 301 mounted within a base frame 400 and a support 302 connected to the transverse shift cylinder 301. The fork assemblies 200 are connected to the support 302, and a transverse shift assembly is mounted on both ends of each fork assembly 200. Specifically, the number of transverse shift cylinders 301 can be one or two, etc. Two transverse shift cylinders 301 can be used in series.

[0061] Specifically, during the X-direction movement of the frame 100, the distance between two adjacent fork assemblies 200 is adjusted to accommodate the size of the sheets being transported. That is, during the X-direction movement of the frame 100, the distance between two adjacent fork assemblies 200 is adjusted. This improves sheet conveying efficiency because the distance between two adjacent fork assemblies 200 does not need to be stopped to change. Instead, the distance is adjusted during the X-direction movement of the frame 100, significantly improving overall sheet conveying efficiency.

[0062] Specifically, a corresponding guide assembly for guiding the fork assembly 200 during the lateral movement may be further provided on the bottom frame 400 .

[0063] In one embodiment, if Figure 17 As shown, a set of fork assemblies 200 are used to transport the plate in a first direction so that the plate enters the first storage position of the shelf. At the same time, a second set of fork assemblies 200 are used to transport the plate in a second direction so that the plate enters the second storage position of the shelf. The first direction is different from the second direction.

[0064] Specifically, according to the above method, the present application can simultaneously transport two plates in different directions into the three-dimensional shelf, which is conducive to improving the efficiency of plate sorting and stacking.

[0065] In one embodiment, the fork assembly 200 moves the plates resting on it in the Y-direction during the ascent or descent of the base frame 400. This arrangement helps save time in plate movement. Once each fork assembly 200 is positioned at the corresponding level of the three-dimensional shelf, the plates can then be transported to their storage locations. During the ascent or descent of the base frame 400, the plates are moved from one end of the fork assembly 200 to the other end. This allows the plate to be transported while the base frame 400 is ascending or descending, effectively utilizing the ascending or descending time of the base frame 400. This saves time and improves efficiency.

[0066] In one embodiment, if Figure 1 and Figure 2 As shown, the first column 102 and the second column 103 are both provided with a vertically extending anti-falling plate 503, and the anti-falling plate 503 is provided with a plurality of slots 5031 from top to bottom, as shown in FIG. Figure 3 As shown, latch mechanisms 600 are respectively provided at both ends of the bottom frame 400. The latch mechanisms 600 include a latch driving mechanism and a latch. The latch driving mechanism is used to drive the latch to extend and retract so that the latch is extended and inserted into the corresponding slot 5031. The number of latches provided on the latch mechanism 600 is at least 2, and the latches are arranged from top to bottom.

[0067] Specifically, there are many implementations of the latch drive mechanism, for example, the latch drive mechanism is a cylinder. After the latch is inserted into the corresponding slot 5031, the bottom frame 400 cannot rise or fall.

[0068] In one embodiment, the latch driving mechanism drives each latch to move simultaneously, so that at least one latch is inserted into the corresponding slot 5031 .

[0069] Specifically, this arrangement can ensure that at least one pin is inserted into the corresponding slot 5031, thereby preventing the bottom frame 400 from falling.

[0070] Specifically, such as Figures 14 to 16 As shown, the latch drive mechanism may include a housing 601, with a latch drive cylinder 602 mounted on one side of the housing 601. The latch drive cylinder 602 is connected to a cylinder push rod 603 disposed in the housing 601. The housing 601 is provided with a first type of through hole 604. The cylinder push rod 603 is disposed corresponding to the first type of through hole 604. A latch is disposed on both sides of the cylinder push rod 603 in the housing 601, namely a first latch 615 and a second latch 616. The box body 601 is also provided with a second type of through hole 605 for the latch to extend out of the box body 601. Bushings are provided at both ends of the cylinder push rod 603. Bushings are also provided at both ends of the above-mentioned latch. The bushings are fixed to the box body 601. Three horizontal long holes are provided on one side wall of the box body 601 from top to bottom. The first horizontal long hole 606 corresponds to the first latch 615, the second horizontal long hole corresponds to the cylinder push rod 603, and the third horizontal long hole corresponds to the second latch 616. , it also includes a connecting plate 609 arranged on the outside of the box body 601, and two vertical long holes are respectively provided at both ends of the connecting plate 609, the first vertical long hole corresponds to the first horizontal long hole, the second vertical long hole corresponds to the third horizontal long hole, an intermediate hole is provided between the two vertical long holes, the intermediate hole corresponds to the second horizontal long hole 607, one end of the first guide shaft 612 passes through the first vertical long hole 610 and the first horizontal long hole 606 and is connected to the first latch 615, the other end of the first guide shaft 612 is provided with a gasket 618 and a positioning pin 617, one end of the second guide shaft 613 passes through the intermediate hole and the second horizontal long hole 607 and is connected to the cylinder push rod 603, the other end of the second guide shaft 613 is provided with a gasket 618 and a positioning pin 617, one end of the third guide shaft 614 passes through the second vertical long hole 611 and the third horizontal long hole 608 and is connected to the second latch 616, and the other end of the third guide shaft 614 is provided with a gasket 618 and a positioning pin 617.

[0071] When the latch driving cylinder 602 drives the cylinder push rod 603 to move laterally, the connecting plate 609 moves together. The movement of the connecting plate 609 drives one end of the first latch 615 and one end of the second latch 616 to extend out of the box body 601 through the first guide shaft 612 and the third guide shaft 614. This causes one end of the first latch 615 to be inserted into the corresponding slot 5031, and one end of the second latch 616 to be inserted into the corresponding slot 5031.

[0072] It is understood that the length of the cylinder push rod 603 is shorter than the length of the latch. When the first latch 615 is extended, it is blocked by the anti-fall plate 503, preventing it from extending normally. At this time, the second latch 616 can continue to move until it extends out of the box 601 and inserts into the corresponding slot 5031. The second latch 616 can continue to move because the connecting plate 609 of the present application is provided with a vertical slot and a horizontal slot. This arrangement allows the connecting plate 609 to swing at a certain angle, so when one latch cannot extend, the other can extend.

[0073] In one embodiment, Figure 1 As shown, the travel wheel is provided on a travel wheel bracket 504, one end of the travel wheel bracket 504 is provided with an extension frame 802 extending along the Y direction, and both ends of the extension frame 802 are provided with a plate detection sensor 801. The plate detection sensor 801 can be a photoelectric sensor.

[0074] When the frame 100 moves on the running wheels, the plate detection sensor 801 can detect whether there are plates on the three-dimensional shelf that are not positioned as required. For example, some plates protrude a certain distance from the three-dimensional shelf. Such plates may hinder the ascent or descent of the fork assembly 200, that is, the ascent or descent of the fork assembly 200 may hit these plates. The detection sensor can detect whether such plates exist. If so, the position of these plates can be manually changed.

[0075] In one embodiment, Figure 3 As shown, a camera 700 is provided on the top of one end of the bottom frame 400 , and the height of the camera 700 is higher than each fork assembly 200 .

[0076] Specifically, the camera 700 can monitor the operation of each fork assembly 200, which is helpful for timely detection of problems.

[0077] The second embodiment of the present application provides a plate sorting and stacking method, which uses the plate sorting and stacking machine to first place the cut plates of different sizes into a three-dimensional shelf through the plate sorting and stacking machine, with only one plate placed in each storage position in the shelf. Then, the plate sorting and stacking machine sorts the plates in the three-dimensional shelf according to demand, so that each plate is taken out from the original storage position and put back into a new storage position.

[0078] The present application can realize the rapid sorting of plates of different sizes through the above method, which is beneficial to improving the overall efficiency of plate processing.

[0079] like Figure 18As shown, the third embodiment of the present application provides a plate sorting and stacking method, which uses the plate sorting and stacking machine described above to take out the first plate from the three-dimensional shelf through the first group of fork assemblies 200, then take out the second plate from the three-dimensional shelf through the second group of fork assemblies 200, and then take out the third plate from the three-dimensional shelf through the third group of fork assemblies 200. During the movement of the frame 100 along the X direction, each plate is transported in the same direction at the same time until each plate rests on the corresponding baffle 224, so that the positions of each plate are aligned. Then, the baffle 224 is rotated from a vertical state to an inclined state, and then each plate is transported to a storage position in the three-dimensional shelf. It can be understood that the above method takes 3 plates as an example. If 2 plates of different sizes are transported, such as Figure 19 As shown, it is also possible to align first and then transport.

[0080] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
