Description

Technical Field

[0001] The invention relates to the technical field of sandwich panel production equipment, and in particular to a sandwich panel stacking system and a stacking method. Background Art

[0002] After the sandwich panels are produced, they are usually stacked and packaged for easy transportation. If the sandwich panels are manually lifted from the production line to the stacking platform for stacking, not only is the efficiency low, but there is a high probability of collisions during transportation, which may damage the surface of the sandwich panels. However, if the sandwich panels are stacked with traditional translational stacking equipment, the orientation of the stacked sandwich panels is usually the same. After the sandwich panels are stacked, the outer side of one of the top or bottom sandwich panels will face the outside. In this case, during the transportation of the sandwich panels, the outer side of the exposed sandwich panel will be bumped, affecting the aesthetics of the final curtain wall.

[0080] Please refer to Figure 1-2 As shown, this embodiment provides a sandwich panel palletizing system, which is used at the end of a sandwich panel production line to palletize the produced sandwich panels to facilitate subsequent packaging and loading and transportation.

[0081] In some embodiments of this application, please refer to Figure 2 As shown, the sandwich panel stacking system includes a conveying mechanism 1 and a translation stacking mechanism 4. The sandwich panel abuts against the conveying surface of the conveying mechanism 1. The conveying mechanism 1 is used to drive the sandwich panel to move to the transport position. The translation stacking mechanism 4 spans over the conveying mechanism 1 and the stacking platform 5, and can lift the sandwich panel from the stacking position of the conveying mechanism 1 and move it to the stacking platform 5 for stacking. This avoids manual handling and stacking, saves labor costs, and is more efficient.

[0082] Specifically, in some embodiments of the present application, please refer to Figure 3-4 As shown, the transmission mechanism 1 includes a transmission frame 11 and a plurality of rotatable transmission rollers arranged in sequence on the transmission frame 11. The sandwich panels are in contact with the transmission rollers. The contact points between the plurality of transmission rollers and the sandwich panels constitute a transmission surface. During the rotation process, the transmission rollers drive the sandwich panels to move to the transmission position along the transmission mechanism 1 through friction. The translation stacking mechanism 4 includes a gantry 41, a translation arm 42, and a suction cup group 43, wherein a plurality of gantry frames 41 are arranged at intervals above the transmission mechanism 1 and the stacking platform 5, the translation arm 42 can be slidably arranged below the gantry 41, and the translation arm 42 can be slidably arranged on a plurality of gantry frames 41 at the same time to ensure the smoothness of the sliding of the translation arm 42. The suction cup group 43 can be raised and lowered on the translation arm 42, and the suction cup group 43 can absorb the sandwich panels and drive the sandwich panels to move to achieve lifting and translation. The lifting mode can be that a lifting motor is provided on the translation arm 42, a winding wheel is provided at the output end of the lifting motor, one end of the lifting rope is provided on the winding wheel, and the other end is provided on the suction cup group 43, and the lifting motor rotates to wind up or unwind the lifting rope to achieve the lifting or lowering of the suction cup group 43. The suction cup group 43 includes a plurality of suction cups 431 arranged at intervals, and the suction cups 431 can be sucked together with the sandwich panel, and connected with the sandwich panel in a sucking manner, which can ensure that the inner and outer surfaces of the sandwich panel will not be damaged to the greatest extent, and ensure the aesthetics of the metal wall formed by the sandwich panel.

[0083] The quality of the outer side of the sandwich panel directly affects the aesthetics of the outer surface of the metal wall. In the process of sandwich panel stacking, it is inevitable that the side above the uppermost sandwich panel of the sandwich panel stack or the side below the lowermost sandwich panel of the sandwich panel stack is the outer side of the sandwich panel. During the transportation of the sandwich panel stack, the outer side of the sandwich panel is exposed to the outside, which will inevitably cause damage during transportation, affecting the quality of the outer side of the sandwich panel, resulting in the scrapping of the sandwich panel or affecting the aesthetics of the metal wall.

[0084] In order to solve the above problems, in some embodiments of the present application, please refer to Figure 3-4 As shown, the sandwich panel stacking system also includes a transverse shifting alignment mechanism 2 and a flipping mechanism 3, wherein the transverse shifting alignment mechanism 2 can be raised and lowered on the transmission mechanism 1. When the transverse shifting alignment mechanism 2 is raised, it is higher than the transmission surface, and can lift up the sandwich panel located on the transmission mechanism 1, and drive the sandwich panel to move toward the inner side of the transmission mechanism 1 until it abuts against the flipping mechanism 3, completing the transverse shifting alignment, and then the transverse shifting alignment mechanism 2 is lowered to be lower than the transmission surface, which does not affect the subsequent transportation of the sandwich panels by the transmission mechanism 1. The flipping mechanism 3 includes an inner rotating arm group 31 and an outer rotating arm group 32 which can rotate toward each other and engage with each other. The outer rotating arm group 32 is arranged on the side of the transmission mechanism 1 facing the stacking platform 5. The inner rotating arm group 31 is arranged on the transmission mechanism 1 and has a gap with the sandwich panel, so as to avoid affecting the transportation of the sandwich panel by the transmission mechanism 1. When the transverse shifting alignment mechanism 2 moves the sandwich panel to abut against the flipping mechanism 3, the inner rotating arm group 31 and the outer rotating arm group 32 rotate toward each other. In the process of the inner rotating arm group 31 rotating toward the outer rotating arm group 32, it first abuts against the sandwich panel, and then drives the sandwich panel to rotate until the sandwich panel rotates more than 90°. Under the action of gravity, the sandwich panel abuts against the outer rotating arm 322, and the outer rotating arm 322 drives the sandwich panel to flip over until the other side of the sandwich panel is flat on the outer rotating arm 322 facing upward, thereby completing the flipping action of the sandwich panel.

[0085] After the sandwich panel is flipped over, the translation arm 42 drives the suction cup group 43 to move to the top of the sandwich panel located on the outer rotating arm group 32, and the suction cup group 43 descends until it abuts against the sandwich panel. The suction cup group 43 sucks up the sandwich panel and follows the translation arm 42 to move to the top of the stacking platform 5, and the suction cup group 43 descends to place the sandwich panel on the stacking platform 5.

[0086] It is understandable that as long as the upper side of the top sandwich panel and the lower side of the bottom sandwich panel of the sandwich panel stack are the inner side of the metal curtain wall, and the processed sandwich panels usually have the outer side of the metal curtain wall facing upward, then in the stacking process, only the last sandwich panel needs to be turned over. If the inner side of the processed sandwich panels that form the metal curtain wall faces upward, then only the first sandwich panel needs to be turned over. There is no need to turn over more sandwich panels, thereby ensuring stacking efficiency.

[0087] Specifically, in some embodiments of the present application, please refer to Figure 3-4 As shown, the transverse shifting alignment mechanism 2 includes a plurality of translational components 22 arranged in sequence and linked together, the translational components 22 are located between two adjacent transmission rollers, and the plurality of translational components 22 can rise and fall simultaneously to ensure that the transverse shifting alignment components can abut against the sandwich panels over a larger area without affecting the transmission mechanism 1 in transmitting the sandwich panels, thereby ensuring the smooth movement of the sandwich panels during the translational alignment process.

[0088] Please refer to Figure 3-4 As shown, the inner rotating arm group 31 includes a plurality of inner rotating arms 312 arranged in sequence and rotatable toward the outer rotating arm group 32. The inner rotating arm 312 is located between two adjacent transmission rollers, and also ensures that a larger area can be abutted against the sandwich panel during the flipping process of the sandwich panel, ensuring the stability of the sandwich panel during the flipping process. The translation assembly 22 and the inner rotating arms 312 are arranged alternately, so that the translation assembly 22 can evenly distribute the sandwich panels, and the inner rotating arms 312 also evenly distribute the sandwich panels.

[0089] Please refer to Figure 3 to Figure 6 As shown, in order to realize the rising and falling of the transverse shifting alignment mechanism 2, the transverse shifting alignment mechanism 2 also includes a lifting assembly 21 located below the translation assembly 22 to drive the translation assembly 22 to rise and fall, and the lifting assembly 21 includes a rotating shaft 211, a lifting member 212, a driving member 213 and a transmission member 214, wherein the rotating shaft 211 is rotatably arranged on the transport frame and is located below between two adjacent transmission rollers, one end of the lifting member 212 is connected to the rotating shaft 211 and rotates with the rotating shaft 211, and the other end is connected to the translation assembly 22, one end of the transmission member 214 is connected to the rotating shaft 211, and the other end is connected to the output end of the driving member 213 to convert the linear driving force of the driving member 213 into the rotational force of the rotating shaft 211. When the output end of the driving member 213 outputs a linear driving force, the end of the transmission member 214 away from the rotating shaft 211 moves following the driving member 213, so that the other end of the transmission member 214 drives the rotating shaft 211 to rotate, and the rotation of the rotating shaft 211 drives the end of the lifting member 212 away from the translation component 22 to rotate following the rotating shaft 211, thereby driving the other end of the lifting member 212 to drive the translation component 22 to rotate around the rotating shaft 211, thereby realizing the rising and falling of the translation component 22. The structure is simple and the operation is convenient.

[0090] It can be understood that the rising and falling amplitude of the translation component 22 does not need to be too large, as long as the highest point of the surface where the translation component 22 abuts against the sandwich panel can be higher than the transmission surface or lower than the transmission surface. Therefore, the rotation angle of the rotating shaft 211 is relatively small, and the moving distance of the output end of the driving member 213 does not need to be very large.

[0091] In order to ensure the smooth movement of the translation assembly 22 during the ascending and descending process, in some embodiments of the present application, please refer to Figure 5 As shown, the lifting assembly 21 also includes a linkage member 215, a rotating shaft 211, a lifting member 212 and a transmission member 214, and the combination of the rotating shaft 211, the lifting member 212 and the transmission member 214 is provided at each end of the translation assembly 22. The two ends of the linkage member 215 are respectively connected to the center of the two transmission members 214, and one of the two transmission members 214 is connected to the output end of the driving member 213. When the transmission member 214 moves, the other transmission member 214 moves with the action of the linkage member 215. Therefore, the lifting members 212 can make the same rotational movement along their respective rotating shafts 211, thereby jointly lifting the translation assembly 22, thereby ensuring the stability of the translation assembly 22 when lifting the sandwich panel.

[0092] In some embodiments of this application, please refer to Figure 5 As shown, a plurality of lifting members 212 are sequentially spaced and sleeved on the rotating shaft 211, and each lifting member 212 is connected to a corresponding translation assembly 22. It should be noted that each lifting member 212 referred to here is a different lifting member 212 located on the same rotating shaft 211. Thus, one lifting mechanism can drive all the translation assemblies 22 to rise or fall.

[0093] In the entire lifting assembly 21, there is at least one driving member 213, and each driving member 213 must correspond to a transmission member 214, but the transmission member 214 does not necessarily correspond to a driving member 213. The driving force of multiple driving members 213 is greater, so that the lifting device can lift a greater weight. The number of driving members 213 can be determined according to actual needs, and this embodiment does not make any specific limitations.

[0094] In some embodiments of this application, please refer to Figure 6 As shown, a possible structure of the translation assembly 22 includes a clamping body, a sprocket 222 and a chain 223, wherein the frame 221 is connected to the end of the lifting member 212 away from the rotating shaft 211, the sprocket 222 is rotatably arranged on the frame 221, the frame 221 has sprockets 222 on both sides along the width direction of the transmission mechanism 1, the two ends of the chain 223 are respectively meshed with the sprockets 222 at both ends of the frame 221, and the outer side of the chain 223 is in contact with the sandwich panel. Thus, the sandwich panel is driven to move toward one side of the transmission mechanism 1.

[0095] In order to ensure that the chain 223 is always kept in a tensioned state during the transmission process, in some embodiments of the present application, please refer to Figure 6As shown, at least two sprockets 222 are staggered on one side of the frame 221. The example of two sprockets 222 on one side of the frame 221 is used for explanation, that is, there are four sprockets 222 meshing with the chain 223, two of which are rotatable and located on the left and right sides below the frame 221, and the other two sprockets 222 are rotatable and located on the left and right sides above the frame 221. The two sprockets 222 on the same side are staggered, so that the sprocket 222 located at the bottom can stretch the length of the chain 223, thereby playing a tensioning role and ensuring good support for the sandwich panel.

[0096] In some embodiments of the present application, the transverse shift alignment mechanism 2 also includes a drive shaft 224, and the sprockets 222 at the same position of different translation components 22 are all mounted on the drive shaft 224, and the drive shaft 224 is connected to the power part. The translation component 22 is still taken as an example with four sprockets 222. The four sprockets 222 are sprocket 222A, sprocket 222B, sprocket 222C and sprocket 222D, wherein sprocket 222A and sprocket 222B are located on both sides above the frame 221, and sprocket 222C and sprocket 222D are located on both sides below the frame 221, and the sprocket 222C on each translation component 22 is mounted on the drive shaft 224, and the transmission of the drive shaft 224 can drive the sprocket 222C to rotate, thereby realizing the movement of the chain 223. In this way, all the translational components 22 can be driven by one power member to simultaneously drive the sandwich panel to move toward one side of the transportation mechanism. The structure is simple, fewer power members are required, the number of power members is saved, the cost is low, and the control program is simplified.

[0097] In some embodiments of this application, please refer to Figure 3-4As shown, the inner rotating arm group 31 also includes an inner rotating shaft 311, which extends along the length direction of the transmission mechanism 1 and can be rotated to be located on the side of the transmission mechanism 1 facing the stacking platform 5. The rotation of the inner rotating shaft 311 can avoid affecting the rotation of the transmission roller. A plurality of inner rotating arms 312 are arranged on the inner rotating shaft 311 on the side facing the stacking platform 5. When the inner rotating shaft 311 rotates toward the direction of the outer rotating arm group 32, it can drive the rotation of the inner rotating arm 312. The outer rotating arm group 32 also includes an outer rotating shaft 321, which is the same length as the inner rotating shaft 311, so that the area where the inner rotating arm group 31 abuts against the sandwich panel is the same as the area where the outer rotating arm group 32 abuts against the sandwich panel, thereby ensuring that the outer rotating arm group 32 stably supports the sandwich panel after flipping. The inner rotating shaft 311 and the outer rotating shaft 321 first rotate towards each other until the sum of their rotation angles is 180° and then rotate away from each other, so that the inner rotating arm 312 and the outer rotating arm 322 can rotate towards each other. There is a gap between the outer rotating shaft 321 and the inner rotating shaft 311. When the sum of the rotation angles of the inner rotating shaft 311 and the rotation angles of the outer rotating shaft 321 is 180°, if there is no gap between the inner and outer rotating shafts 211, the inner rotating arm 312 and the outer rotating arm 322 will abut against each other, and the two will squeeze the sandwich panel located in the center. Therefore, the gap between the inner and outer rotating shafts 211 allows space for accommodating the sandwich panel between the inner rotating arm 312 and the outer rotating arm 322, thereby ensuring that the sandwich panel will not be damaged during the flipping process.

[0098] In some embodiments of the present application, the rotation angle of the inner rotation axis 311 is greater than or equal to 100° and less than or equal to 110°, and the rotation angle of the outer rotation axis 321 is greater than or equal to 70° and less than or equal to 80°. The inner rotation arm 312 can drive the sandwich panel to rotate greater than or equal to 100°, at which time the sandwich panel will continue to rotate downward under the action of gravity until it abuts against the outer rotation arm 322, and the outer rotation arm 322 supports and drives the sandwich panel to rotate along the outer rotation axis 321 in a direction away from the inner rotation axis 311 until the sandwich panel is laid flat on the outer rotation arm 322.

[0099] Further, in order to ensure the position of the sandwich panel when driven by the translation assembly 22, in some embodiments of the present application, please refer to Figure 3-4As shown, the flip mechanism 3 also includes a limit block. Along the width direction of the transmission mechanism, the inner rotating arm 312 is located at the end of the inner rotating shaft 311 and the outer rotating arm 322 is located at the end of the outer rotating shaft 321. The transverse displacement alignment mechanism 2 can move the sandwich panel to abut against the limit block, thereby ensuring the position of the sandwich panel before flipping, and will not move toward the side of the transmission mechanism 1 during the flipping process, thereby avoiding collision and ensuring that the sandwich panel will not be damaged. The length of the limit block is longer than the gap, and the gap is greater than or equal to the thickness of the sandwich panel. The length of the gap can ensure the accommodation space of the sandwich panel when the sum of the rotation angles of the inner rotating arm 312 and the outer rotating arm 322 is equal to 180°, and the inner and outer rotating arms 322 will not squeeze the sandwich panel. When the inner rotating arm 312 drives the sandwich panel to rotate 90° to a vertical state, the sandwich panel will not fall from the gap. In addition, a soft anti-collision structure is provided on one side of the limit block facing the sandwich panel. The anti-collision structure can be made of sponge material or rubber material to ensure that the sandwich panel will not be damaged.

[0100] In the process of flipping the sandwich panel, in order to prevent the limit blocks on the inner and outer rotating arms 322 from colliding with each other, please refer to Figure 3-4 As shown, the limit block on the inner rotating arm 312 and the limit block on the outer rotating arm 322 are staggered, that is, when the limit block on the inner rotating arm 312 is set on the left side of the inner rotating arm 312, the rotating block on the outer rotating arm 322 is set on the right side of the outer rotating arm 322, all the limit blocks of the inner rotating arm 312 are set on the left side of the inner rotating arm 312, and all the limit blocks on the outer rotating arm 322 are set on the right side of the outer rotating arm 322. When the sandwich panel needs to be turned over, the inner rotating arm 312 and the outer rotating arm 322 rotate towards each other until the sum of the rotation angles of the inner rotating arm 312 and the outer rotating arm 322 is 180°. At this time, the sandwich panel rotates from the inner rotating arm 312 to abut against the outer rotating arm 322 under the action of gravity, and the outer rotating arm 322 begins to rotate in the direction away from the inner rotating arm 312 until the sandwich panel is flat on the outer rotating arm 322. At this time, the inner rotating arm 312 rotates again in the direction away from the outer rotating arm 322 to reset, thereby avoiding the interference between the limit block and the sandwich panel caused by the inner rotating arm 312 and the outer rotating arm 322 rotating away from each other at the same time.

[0101] In some embodiments of this application, please refer to Figure 3-4As shown, the length of the transmission frame 11 is longer than the length of the sandwich panel, so that the length of the transmission mechanism 1 is longer than the length of the sandwich panel, so that multiple sandwich panels can be arranged in sequence on the transmission mechanism 1. The transmission mechanism 1 also includes a signal alignment group 13, and multiple signal alignment groups 13 are arranged at intervals on the transmission mechanism 1. The transmission mechanism 1 can sequentially transmit multiple sandwich panels to the signal alignment group 13, that is, the transmission mechanism 1 is provided with multiple transmission positions, each transmission position corresponds to a signal alignment group 13, and the sandwich panels can be sequentially transmitted to the transmission position, and will not move further after reaching the transmission position.

[0102] Specifically, the signal alignment group 13 includes an infrared transmitter and an infrared receiver arranged opposite to each other in the up and down directions. The signal alignment group 13 is coupled to a rotating motor that drives the transmission roller to rotate. At the same time, the signal alignment group 13 and the rotating motor are coupled to the control device at the same time. The multiple transmission rollers on the transmission frame 11 are divided into multiple transmission roller groups, and each transmission roller group has a rotating motor. When the sandwich panel reaches the transmission position, it will block the infrared light emitted by the infrared transmitter. The infrared receiver cannot receive the infrared signal, and the signal alignment group 13 transmits the information to the control device. The control device recognizes that the signal alignment group 13 located upstream of the blocked signal alignment group 13 is in a blocked state, then it recognizes that another sandwich panel has arrived at the transmission position, then the rotating motor of the transmission roller group below the sandwich panel is controlled to stop working, and the motor of the transmission roller group downstream of the transmission roller group continues to work, thereby realizing the work of transmitting the sandwich panels to the transmission positions in sequence. In more detail, assume that there are 5 groups of transmission roller groups on the transmission frame 11, namely transmission roller group a, transmission roller group b, transmission roller group c, transmission roller group d and transmission roller group e, and the transmission roller groups a to transmission roller group e are arranged in sequence along the direction of transmission of the sandwich panel by the transmission mechanism 1. The transmission roller group a corresponds to the signal corresponding group 13a, the transmission roller group b corresponds to the signal corresponding group b, the transmission roller group c corresponds to the signal corresponding group c, the transmission roller group d corresponds to the signal corresponding group d, and the transmission roller group e corresponds to the signal corresponding group e. When the first sandwich panel moves on the transmission mechanism 1, it will pass through the transmission roller group e, the transmission roller group d, the transmission roller group c and the transmission roller group b and finally stop on the transmission roller group a. In this process, the sandwich panel will sequentially block the signal alignment group 13e, the signal alignment group 13d, the signal alignment group 13c, the signal alignment group 13b and the signal alignment group 13a. When the signal alignment group 13e is blocked, the signal alignment group 13e will transmit the information that the infrared rays are blocked to the control device. The control device recognizes that the signal alignment group 13d, the signal alignment group 13c, the signal alignment group 13b and the signal alignment group 13a located upstream of the signal alignment group 13e are not blocked. Then the control device controls the rotating motor of the transmission roller group e to continue working. When the sandwich panel passes through the alignment signal group d, the control device recognizes that the signal alignment group 13c, the signal alignment group 13b and the signal alignment group 13a located upstream of the signal alignment group 13d are not blocked. Then the control device controls the rotating motor of the transmission roller group d to continue working until the sandwich panel blocks the signal alignment group 13a. The signal alignment group 13a transmits the information that the infrared rays are blocked to the control device. The control device controls the rotating motor corresponding to the transmission roller group a to stop working, while the other rotating motors continue to work. At this time, the first sandwich panel stops at the transmission position corresponding to the signal alignment group 13a.When the second sandwich panel is transmitted on the transmission mechanism 1, it will pass through the transmission roller group e to the transmission roller group b respectively, and will block the signal alignment group 13e to the signal alignment group 13b in turn. When the second sandwich panel blocks the signal alignment group 13e, the control device recognizes that the signal alignment group 13c and the signal alignment group 13b are both in an unblocked state. At this time, the rotating motor corresponding to the transmission roller group e continues to work until the second sandwich panel moves along the transmission component to block the signal alignment group 13d. The control device recognizes that the infrared signal on the signal alignment group 13e has been blocked. At this time, the control device controls the rotating motor corresponding to the transmission roller group d to stop working, and the second sandwich panel stops at the transmission position corresponding to the signal alignment group 13d. This process is deduced in the same way until the five sandwich panels are evenly distributed on the transmission mechanism 1.

[0103] Corresponding to the length of the transmission mechanism 1 , the length of the translation arm 42 matches the length of the transmission mechanism 1 , and each suction cup group 43 corresponds to a sandwich panel.

[0104] It can be understood that the length of the sandwich panels can be long or short. When the length of the sandwich panels is longer than the length of a transmission roller group, the signal alignment groups 13 at intervals can be closed corresponding to the length of the sandwich panels when the sandwich panels are transmitted on the transmission mechanism 1. For example, if the length of the sandwich panels to be transmitted is longer than the length of one transmission roller group but less than the length of two transmission roller groups, the above-mentioned five transmission roller groups are still used as an example for explanation. At this time, two sandwich panels can be placed on the transmission mechanism 1 at the same time. First, the positions of the sandwich panels are determined. The first sandwich panel can be located at the transmission position corresponding to the signal alignment group 13a, and the second sandwich panel can be located at the transmission position corresponding to the signal alignment group 13c, or at the transmission position corresponding to the signal alignment group 13d. Taking the second sandwich panel being located at the transmission position corresponding to the signal alignment group 13d as an example, the signal alignment group 13b, the signal alignment group 13c and the signal alignment group 13e can be closed. At this time, the rotating motors corresponding to the transmission roller group b, the transmission roller group c and the transmission roller group e are in a state of being constantly working.

[0105] However, if the length of the sandwich panel is very short, a large amount of electric energy will be wasted if the translation stacking mechanism 4 is used for lifting. Therefore, in some embodiments of the present application, please refer to Figure 1As shown, the sandwich panel palletizing system further includes a mechanical handling arm 6, which is located between the transmission mechanism 1 and the palletizing platform 5 and is used to carry the shorter sandwich panels to the palletizing platform 5. In order to further save electric energy, a small conveying platform may be provided at the end of the transmission mechanism 1 away from the sandwich panel production line. In the process of transporting the shorter sandwich panels, all the signal alignment groups 13 on the transmission mechanism 1 do not work, all the transmission rollers rotate all the time, and the sandwich panels move along the transmission mechanism 1 to the transmission platform. There is a mechanical handling arm 6 between the transmission platform and the palletizing platform 5, and the mechanical handling arm 6 can move the shorter sandwich panels on the transmission platform to the palletizing platform 5 for palletizing, thereby saving more electric energy.

[0106] The embodiment of the present application further provides a palletizing method based on the above sandwich panel palletizing system, and the palletizing method includes:

[0107] S10, the transmission mechanism 1 transports the first batch of sandwich panels to the transport position in sequence;

[0108] S20, the translation alignment mechanism rises until it abuts against the sandwich panel, drives the sandwich panel to leave the transmission surface, and drives the sandwich panel to move toward one side of the stacking platform 5;

[0115] S11. The sandwich panels are moved to the corresponding transmission positions on the transmission mechanism 1 in sequence. When passing through the transmission roller group on the non-corresponding transmission position, even if the signal alignment device is blocked, the control device controls the transmission roller group not to stop working until it moves to the transmission roller group on the corresponding transmission position, at which time the transmission roller group on the corresponding transmission position stops working.

[0116] S12, the subsequent sandwich panels repeat the step S11 until the first batch of sandwich panels are evenly spaced on the transmission mechanism 1.

[0117] When the first batch of sandwich panels are transported to the corresponding transmission mechanisms 1, S20, the translation alignment mechanism rises to abut against the sandwich panels, drives the sandwich panels to leave the transmission surface, and drives the sandwich panels to move toward one side of the stacking platform 5, including:

[0118] S21, the lifting mechanism drives the translation assembly 22 to rise, and the translation assembly 22 abuts against the sandwich panel during the rising process and drives the sandwich panel to continue to rise until it is separated from the transmission surface;

[0119] S22, the translation assembly 22 drives the sandwich panel to move toward the stacking platform 5 until it abuts against the limiting plate;

[0120] S30, the translation stacking mechanism 4 translates the flipped sandwich panels onto the stacking platform 5, including:

[0121] S31, the inner rotating shaft 311 and the outer rotating shaft 321 rotate towards each other, and the inner rotating arm 312 first abuts against the sandwich panel during the process of rotating toward the outer rotating arm 322, and drives the sandwich panel to rotate together, until the sum of the rotation angles of the inner rotating arm 312 and the outer rotating arm 322 is 180 degrees, and the sandwich panel moves to abut against the outer rotating arm 322 under the action of gravity;

[0122] S32, the outer rotating arm 322 drives the sandwich panel to move in a direction away from the inner rotating arm 312 until the sandwich panel is laid flat on the outer rotating arm 322;

[0123] S33, the inner rotating arm 312 rotates in a direction away from the outer rotating arm 322 until it is reset;

[0124] S34, the lifting mechanism drives the translation assembly 22 to descend to reset.

[0125] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
