[0038] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, features in the following embodiments can be combined with each other.

[0039] First Embodiment Please refer to the reference. Figure 1 and Figure 2 This invention provides a strapping and palletizing system 10 for strapping and palletizing sheet metal units 21. It enables automated conveying, strapping, and unloading of the sheet metal units 21, effectively shortening the strapping and palletizing cycle, improving efficiency, saving labor and time costs, and increasing economic benefits.

[0040] The palletizing system 10 includes a conveying device 200, a strapping mechanism 300, a feeding mechanism 400, and at least two support frames 110. The conveying device 200 and the feeding mechanism 400 are arranged adjacent to each other. The conveying device 200 is used to buffer and convey the support frames 110, the strapping mechanism 300 is used to strap the board units 21, and the feeding mechanism 400 is used to feed the board units 21.

[0041] Furthermore, the conveying device 200 has a loading station, a strapping station, and a buffer station. The conveying device 200 is used to transport a carrier frame 110 containing multiple sheet metal units 21 from the loading station to the strapping station. The strapping mechanism 300 is used to strap the multiple sheet metal units 21 on the carrier frame 110 at the strapping station to form a sheet metal unit group. The conveying device 200 is also used to transport the carrier frame 110 containing the sheet metal unit group from the strapping station to the unloading mechanism 400. The unloading mechanism 400 is used to unload the sheet metal unit group through the carrier frame 110. The unloading mechanism 400 is also used to return the carrier frame 110 to the conveying device 200. The conveying device 200 is also used to buffer other carrier frames 110 at the buffer station. Specifically, by simultaneously setting up a loading station, a strapping station, and a buffer station on the conveying device 200, the automated conveying, strapping, and unloading of the board unit 21 can be achieved, effectively shortening the strapping and palletizing cycle, improving strapping and palletizing efficiency, saving labor and time costs, and improving economic benefits.

[0042] In this embodiment, the board unit 21 is a ceramic tile, which can be a single tile or a stack of tiles. The tiles can be stacked on the support frame 110 in different ways, and the support frame 110 can support and limit the position of the tiles. However, it is not limited to this. In other embodiments, the board unit 21 can also be stone or wood, and the type of board unit 21 is not specifically limited. The conveying device 200 includes a conveying mechanism 210 and a transfer buffer mechanism 220 arranged adjacent to each other. The loading station and the strapping station are both located on the conveying mechanism 210. The conveying mechanism 210 is used to transport a carrier frame 110 containing multiple sheet metal units 21 from the loading station to the strapping station. The conveying mechanism 210 is also used to transport a carrier frame 110 containing a group of sheet metal units from the strapping station to the unloading mechanism 400. The buffer station is located on the transfer buffer mechanism 220, which is used to buffer other carrier frames 110 at the buffer station.

[0043] Optionally, the buffer station is located outside the line connecting the conveying mechanism 210 and the unloading mechanism 400, meaning that the empty buffer carrier 110 will not interfere with the conveying of the carrier 110 containing multiple sheet metal units 21. Specifically, when the unloading mechanism 400 unloads a group of sheet metal units on one carrier 110, the transfer buffer mechanism 220 sends another carrier 110 to the conveying mechanism 210 to facilitate the rapid strapping and unloading of the next batch of sheet metal units 21, further improving the efficiency of strapping and palletizing.

[0044] The transfer and buffer mechanism 220 includes a first transfer section 221 and a reciprocating buffer section 222. A buffer station is located in the reciprocating buffer section 222. The conveying mechanism 210, the first transfer section 221, and the unloading mechanism 400 are arranged sequentially along a first direction, and the first transfer section 221 and the reciprocating buffer section 222 are arranged sequentially along a second direction. The first and second directions are set at a preset angle. Specifically, the first transfer section 221 is used to transport the carrier frame 110 containing the sheet metal unit group from the conveying mechanism 210 to the unloading mechanism 400. The first transfer section 221 is also used to transport the carrier frame 110 returned from the unloading mechanism 400 to the reciprocating buffer section 222. The reciprocating buffer section 222 is used to buffer the carrier frame 110. The reciprocating buffer section 222 is also used to transport the carrier frame 110 back to the first transfer section 221. The first transfer section 221 is also used to transport the carrier frame 110 discharged from the reciprocating buffer section 222 to the conveying mechanism 210. Furthermore, after the first transfer section 221 sends the carrier frame 110 containing the board unit group to the unloading mechanism 400, the reciprocating buffer section 222 sends another carrier frame 110 to the first transfer section 221. Then, the first transfer section 221 sends the carrier frame 110 to the conveying mechanism 210. After that, the conveying mechanism 210 sends the carrier frame 110 to the loading station to facilitate the rapid strapping and unloading of the next batch of board units 21.

[0045] In this embodiment, the preset angle formed between the first direction and the second direction is 90 degrees, that is, the first direction is perpendicular to the second direction, so as to achieve a reasonable layout of the entire palletizing system 10 and facilitate installation and maintenance. However, it is not limited to this. In other embodiments, the preset angle formed between the first direction and the second direction can be 45 degrees or 30 degrees. There is no specific limitation on the preset angle formed between the first direction and the second direction.

[0046] Please refer to the reference. Figures 3 to 5 The first transfer section 221 includes a mounting frame 2211, a first conveying assembly 2212, a lifting assembly 2213, and a second conveying assembly 2214. Both the first conveying assembly 2212 and the lifting assembly 2213 are mounted on the mounting frame 2211. The lifting assembly 2213 is connected to the second conveying assembly 2214 and is used to raise or lower the second conveying assembly 2214 so that the top surface of the second conveying assembly 2214 is higher or lower than the top surface of the first conveying assembly 2212. The conveying direction of the first conveying assembly 2212 is the same as the conveying direction of the conveying mechanism 210, and both are in the first direction. The conveying direction of the second conveying assembly 2214 is the same as the conveying direction of the reciprocating buffer section 222, and both are in the second direction.

[0047] Specifically, when the top surface of the second conveying component 2214 is higher than the top surface of the first conveying component 2212, the support frame 110 is supported on the second conveying component 2214. At this time, the first transfer section 221 conveys the support frame 110 through the second conveying component 2214, so that the support frame 110 moves from the first transfer section 221 to the reciprocating buffer section 222, or moves from the reciprocating buffer section 222 to the first transfer section 221. When the top surface of the second conveying component 2214 is lower than the top surface of the first conveying component 2212, the support frame 110 is supported on the first conveying component 2212. At this time, the first transfer section 221 conveys the support frame 110 through the first conveying component 2212, so that the support frame 110 moves from the conveying mechanism 210 through the first transfer section 221 to the unloading mechanism 400, or moves from the first transfer section 221 to the conveying mechanism 210.

[0048] In this embodiment, the lifting assembly 2213 is driven by an electric cylinder, but it is not limited to this. In other embodiments, the lifting assembly 2213 may also be driven by a pneumatic cylinder or a hydraulic cylinder.

[0049] Optionally, the first conveying assembly 2212 includes a first driving member 22121, a driving wheel 22122, a driven wheel 22123, and a transmission member 22124. Both the driving wheel 22122 and the driven wheel 22123 are rotatably mounted on the mounting frame 2211. The first driving member 22121 is connected to the driving wheel 22122, and the driving wheel 22122 is connected to the driven wheel 22123 via the transmission member 22124. The transmission member 22124 supports the support frame 110. Specifically, the transmission member 22124 can be a transmission belt, a transmission chain, or a transmission mesh belt. The first driving member 22121 drives the driving wheel 22122 to rotate, and the driving wheel 22122 drives the driven wheel 22123 to rotate via the transmission member 22124. During this process, the transmission member 22124 synchronously drives the support frame 110 to move, thereby realizing the conveying function of the support frame 110.

[0050] Optionally, the second conveying assembly 2214 includes a roller frame 22141, a second driving member 22142, and multiple conveying rollers 22143. The lifting assembly 2213 is connected to the roller frame 22141. The multiple conveying rollers 22143 are arranged in parallel at intervals and are rotatably mounted within the roller frame 22141. The conveying rollers 22143 support the support frame 110. Specifically, the second driving member 22142 is simultaneously connected to the multiple conveying rollers 22143, and the second driving member 22142 drives the multiple conveying rollers 22143 to rotate synchronously, thereby synchronously moving the support frame 110 and realizing the conveying function of the support frame 110.

[0051] In this embodiment, the reciprocating buffer section 222 drives the support frame 110 to move through roller transmission, but it is not limited to this. In other embodiments, the reciprocating buffer section 222 can also drive the support frame 110 to move through belt transmission or chain plate transmission. The transmission form of the reciprocating buffer section 222 is not specifically limited.

[0052] Please continue to refer to Figure 1 and Figure 2 In this embodiment, there are two of each of the following: the first transfer section 221, the conveying mechanism 210, the strapping mechanism 300, and the unloading mechanism 400. A reciprocating buffer section 222 is positioned between the two first transfer sections 221. Each conveying mechanism 210, each first transfer section 221, and each unloading mechanism 400 are sequentially arranged along a first direction. Each strapping mechanism 300 is installed at a strapping station of a conveying mechanism 210. Specifically, the two first transfer sections 221, the two conveying mechanisms 210, the two strapping mechanisms 300, and the two unloading mechanisms 400 respectively form two strapping and palletizing lines. These two lines work together to simultaneously achieve the strapping and palletizing of two batches of board units 21, further improving the strapping and palletizing efficiency.

[0053] It should be noted that the strapping and palletizing system 10 also includes a feeding mechanism 500, which is used to feed and stack multiple board units 21 onto a support frame 110 located at the feeding station, so as to realize the automatic palletizing function of the strapping and palletizing system 10 and further improve the strapping and palletizing efficiency.

[0054] Furthermore, during the operation of the palletizing system 10, the loading mechanism 500 first places multiple board units 21 onto a support frame 110 located at the loading station; then the conveying mechanism 210 transports the support frame 110 containing multiple board units 21 from the loading station to the strapping station; next, the strapping mechanism 300 straps the multiple board units 21 on the support frame 110 at the strapping station to form a board unit group; then the conveying mechanism 210 transports the support frame 110 containing the board unit group from the strapping station to the first transfer section 221; then the first transfer section 221 transports the support frame 110 containing the board unit group to the unloading mechanism 400; then the unloading mechanism 400 unloads the board unit group through the support frame 110; after unloading is completed, the unloading mechanism 400 returns the empty support frame 110 to the first transfer section 221, and then the first transfer section 221 transports the empty support frame 110 to the reciprocating buffer section 222, waiting for the next use. When the carrier 110 buffered on the reciprocating buffer section 222 is needed, the reciprocating buffer section 222 sends the carrier 110 to the first transfer section 221, then the first transfer section 221 sends the carrier 110 to the conveying mechanism 210, and then the conveying mechanism 210 sends the carrier 110 to the loading station.

[0055] In this embodiment, the feeding mechanism 500 is located between the two conveying mechanisms 210, that is, the feeding mechanism 500 is located between the two strapping and palletizing lines. The reciprocating buffer section 222 can only buffer one empty carrier frame 110 at a time. When one strapping and palletizing line is strapping, conveying or unloading, the feeding mechanism 500 pallets and feeds the other strapping and palletizing line to ensure that the feeding mechanism 500 is always in operation and to improve the strapping and palletizing efficiency.

[0056] Furthermore, the operating times of the feeding mechanism 500, the first transfer section 221, the conveying mechanism 210, the strapping mechanism 300, and the unloading mechanism 400 satisfy the following formula: T≤t1+t2+t3+t4+t5; In the formula, T is the feeding time of the feeding mechanism 500; t1 is the transportation time of the conveying mechanism 210 from the feeding station to the first transfer section 221 to transport the carrier frame 110 containing multiple board units 21; t2 is the transportation time of the first transfer section 221 to the unloading mechanism 400; t3 is the transportation time of the reciprocating buffer section 222 to the first transfer section 221; t4 is the transportation time of the first transfer section 221 to the conveying mechanism 210; and t5 is the transportation time of the conveying mechanism 210 to the feeding station.

[0057] Specifically, after the feeding mechanism 500 completes feeding at the feeding station of the first strapping and palletizing line, the feeding mechanism 500 immediately feeds at the feeding station of the second strapping and palletizing line. During this process, firstly, the conveying mechanism 210 of the first strapping and palletizing line sends the carrier frame 110 containing multiple board units 21 from the feeding station to the strapping station; then, the strapping mechanism 300 of the first strapping and palletizing line straps the multiple board units 21 on the carrier frame 110 to form board unit groups; next, the conveying mechanism 210 of the first strapping and palletizing line sends the carrier frame 110 containing the board unit groups to the first transfer section 221; then, the first transfer section 221 of the first strapping and palletizing line sends the carrier frame 110 containing the board unit groups to the unloading mechanism 400; in the second... When the unloading mechanism 400 of a strapping and palletizing line unloads the sheet metal unit group through the support frame 110, the reciprocating buffer section 222 sends the empty support frame 110 buffered on it to the first transfer section 221 of the first strapping and palletizing line. Then, the first transfer section 221 and the conveying mechanism 210 jointly send the empty support frame 110 to the loading station of the first strapping and palletizing line to wait for the next stacking. After the unloading mechanism 400 of the first strapping and palletizing line finishes unloading, the unloading mechanism 400 of the first strapping and palletizing line sends the empty support frame 110 back to the first transfer section 221. Then, the first transfer section 221 sends the empty support frame 110 to the reciprocating buffer section 222 for buffering. Afterwards, the feeding mechanism 500 completes the feeding at the feeding station of the second strapping and palletizing line, and the feeding mechanism 500 immediately feeds the first strapping and palletizing line. During this process, the second strapping and palletizing line performs the above steps accordingly, and so on, ensuring that the feeding mechanism 500 is always in operation, effectively shortening the strapping and palletizing cycle and improving the strapping and palletizing efficiency.

[0058] Furthermore, to ensure the smooth operation of the above steps, the running time of the feeding mechanism 500, the first transfer section 221, the conveying mechanism 210, the strapping mechanism 300, and the unloading mechanism 400 are limited by T≤t1+t2+t3+t4+t5. This ensures that the feeding mechanism 500 can alternately feed materials to the two strapping palletizing lines, achieving a close connection between the feeding processes of the two strapping palletizing lines, shortening the strapping palletizing cycle, and improving the strapping palletizing efficiency.

[0059] In this embodiment, the feeding mechanism 500 is a robotic arm.

[0060] Please refer to the reference. Figures 6 to 13The conveying mechanism 210 includes a conveying frame 211, a third conveying component 212, and a first clamping component 213. Specifically, the third conveying component 212 and the first clamping component 213 are both installed on the conveying frame 211. The third conveying component 212 is used to convey the carrier frame 110, and the first clamping component 213 is set at the loading station to clamp and fix the carrier frame 110 to ensure the stability of the loading and stacking process.

[0061] It should be noted that the support frame 110 includes at least two frame bodies 114, which are arranged side by side. Adjacent frame bodies 114 may be detachably connected or not connected. Each frame body 114 is used to stack a set of board units 21. In this embodiment, there are two frame bodies 114, which are detachably connected. However, this is not the only embodiment. In other embodiments, there may be three or four frame bodies 114, and there may be no connection between adjacent frame bodies 114. The number and connection relationship of the frame bodies 114 are not specifically limited.

[0062] In existing technologies, most palletizing equipment only supports palletizing single-layer brick packages. When faced with high-capacity palletizing demands, the operating efficiency is low, requiring a large amount of manual intervention for adjustment, resulting in low automation and a high degree of danger. In response, the carrier frame 110 of this application realizes the palletizing and conveying of multiple sets of board units 21 through at least two frame bodies 114 arranged side by side, which greatly improves palletizing efficiency and increases the capacity of the packaging production line.

[0063] Optionally, a connecting rod 1141 is provided extending along the parallel direction of at least two frame bodies 114. The free end of the connecting rod 1141 is provided with a locking structure 1142 or a mating structure 1143. The locking structure 1142 of one frame body 114 is mated with the mating structure 1143 of the adjacent frame body 114 to realize a detachable connection between the two frame bodies 114 and fix the relative position of the two frame bodies 114.

[0064] In this embodiment, the locking structure 1142 includes a pin 1144, which extends vertically. The mating structure 1143 includes a socket 1145, and the pin 1144 is inserted into the socket 1145. Specifically, the pin 1144 extends vertically from top to bottom. When the insertion and engagement between the pin 1144 and the socket 1145 is released, the frame body 114 with the pin 1144 is lifted upwards to disengage the pin 1144 from the socket 1145. When the insertion and engagement between the pin 1144 and the socket 1145 is restored, the frame body 114 with the pin 1144 is lowered downwards to allow the pin 1144 to be inserted into the socket 1145. However, this is not the only option. In other embodiments, the pin 1144 extends vertically from bottom to top. When the pin 1144 is disengaged from the socket 1145, the frame body 114 with the socket 1145 is lifted upwards to disengage the pin 1144 from the socket 1145. When the pin 1144 is re-engaged from the socket 1145, the frame body 114 with the socket 1145 is lowered downwards to allow the pin 1144 to be inserted into the socket 1145.

[0065] Furthermore, the conveying mechanism 210 also includes a lifting assembly 130 and a stop assembly 140. Both the lifting assembly 130 and the stop assembly 140 are installed on the conveying frame 211. The lifting assembly 130 is used to lift the frame body 114 upward to separate it from the third conveying assembly 212. The stop assembly 140 is used to stop and limit the frame body 114.

[0066] Specifically, the lifting assembly 130 is used to lift at least one frame body 114 upward relative to the other frame bodies 114, thereby separating the lifted frame body 114 from the third conveying assembly 212. If there is a locking engagement structure between the two frame bodies 114, when the lifting assembly 130 lifts at least one frame body 114 upward relative to the other frame bodies 114 and separates it from the third conveying assembly 212, the pin 1144 can disengage from the insertion hole 1145, releasing the connection between the two adjacent frame bodies 114. Afterwards, the third conveying assembly 212 drives the other frame bodies 114 to continue moving, so that the two frame bodies 114 separate, facilitating the stacking of the sheet metal units 21. After the sheet metal units 21 are stacked, the third conveying component 212 drives the other frame bodies 114 to reset, so that the two frame bodies 114 are closed. At this time, the lifting component 130 is also used to drive at least one frame body 114 to descend and reset relative to the other frame bodies 114 and place it on the third conveying component 212. At this time, the positions of the two sets of sheet metal units 21 on the closed frame bodies 114 are more closely aligned, which can effectively reduce the gap between the two sets of sheet metal units 21. If there is a locking engagement structure between the two frame bodies 114, when the lifting component 130 drives at least one frame body 114 to descend and reset relative to the other frame bodies 114 and place it on the third conveying component 212, the pin 1144 can be inserted into the insertion hole 1145 to realize the detachable connection between the two adjacent frame bodies 114.

[0067] This application, by setting up a lifting component 130 and independently configured support frame 110 and conveying mechanism 210, can not only realize the conventional stacking of single-unit board materials 21, but also the layered stacking, synchronous conveying, and close positioning of multiple sets of board materials 21, effectively improving the automation level and operating efficiency of the packaging production line. Furthermore, based on the independently configured support structure relationship between the support frame 110 and the conveying mechanism 210, the conveying mechanism 210 acts as a power drive module to support and move the support frame 110, eliminating the need for complex electrical or other structures in the support frame 110 itself, simplifying the structure and making daily maintenance easier and more convenient. Moreover, due to the simple structure of the support frame 110 in this application, it can be flexibly combined from multiple frame bodies 114 according to the actual size of the board material units 21, resulting in stronger size adaptability and significantly improving the efficiency of production conversion when switching between board material units 21 of different sizes.

[0068] The lifting assembly 130 includes a lifting drive 131 and a lifting platform 132. The lifting drive 131 is connected to the lifting platform 132. The lifting drive 131 is used to drive the lifting platform 132 to rise, thereby lifting the frame body 114 upward. The lifting drive 131 is also used to drive the lifting platform 132 to fall, so that the frame body 114 returns to its original position. Specifically, the lifting platform 132 is disposed on a horizontal plane, and the lifting drive 131 can drive the lifting platform 132 to rise or fall in the vertical direction, so that the frame body 114 rises or falls.

[0069] Accordingly, the stop assembly 140 is used to stop and limit the frame body 114 so that the position of the frame body 114 corresponds to the position of the lifting assembly 130, thereby ensuring that the lifting assembly 130 can stably and reliably drive the frame body 114 to rise or fall.

[0070] The stop assembly 140 includes a stop drive member 141 and a lifting stop lever 142. The stop drive member 141 is connected to the lifting stop lever 142. The stop drive member 141 is used to drive the lifting stop lever 142 to rise, thereby stopping the frame body 114. The stop drive member 141 is also used to drive the lifting stop lever 142 to fall, thereby canceling the stop on the frame body 114. Specifically, the stop drive member 141 can drive the lifting stop lever 142 to rise or fall in the vertical direction, thereby stopping or canceling the stop on the frame body 114.

[0071] In this embodiment, there are two frame bodies 114; there is one lifting component 130, which is used to lift one of the frame bodies 114; and there are three stop components 140, which are used to stop and limit the two frame bodies 114 at different positions.

[0072] It is worth noting that, when the lifting assembly 130 is in a preset position, during the separation process of the two frame bodies 114, the third conveying assembly 212 firstly drives the two detachably connected frame bodies 114 to move forward in a preset direction. When the first frame body 114 passes the preset position and the second frame body 114 has not yet reached the preset position, the first stop assembly 140 rises to stop the second frame body 114, causing the second frame body 114 to pause at the preset position and simultaneously pausing the first frame body 114, while the third conveying assembly 212 also pauses. Subsequently, the lifting assembly 130 lifts the second frame body 114 upwards so that it connects with the third conveying assembly 212. When component 212 separates, the pin of the first frame body 114 disengages from the insertion hole 1145 of the second frame body 114, thus terminating the connection between the two frame bodies 114. Then, the third conveying assembly 212 is activated to drive the first frame body 114 to continue moving forward, thereby separating the two frame bodies 114. Then, the second stop assembly 140 rises to stop the first frame body 114, so that the distance between the two frame bodies 114 reaches the preset distance. At this time, the third conveying assembly 212 stops. Then, the lifting assembly 130 drives the second frame body 114 to descend and reset, so that the plate unit 21 can be stacked on the two spaced-apart frame bodies 114.

[0073] During the closing process of the two frame bodies 114, the lifting assembly 130 first lifts the second frame body 114 upward; then the third conveying assembly 212 is activated to drive the first frame body 114 back, thereby closing the two frame bodies 114; next, the third stop assembly 140 rises to stop the first frame body 114, so that the pin of the first frame body 114 and the insertion hole 1145 of the second frame body 114 correspond in position; then the lifting assembly 130 drives the second frame body 114 to descend and reset, so that the pin of the first frame body 114 and the insertion hole 1145 of the second frame body 114 are engaged, realizing the detachable connection of the two frame bodies 114, so as to facilitate the conveying of the plate unit 21.

[0074] In this embodiment, both the lifting drive component 131 and the stop drive component 141 are electric cylinders, pneumatic cylinders, or hydraulic cylinders.

[0075] In this way, during the loading process, the conveying mechanism 210 drives the two frame bodies 114 to separate, so that a preset gap is formed between the two frame bodies 114. This prevents the gap between the two frame bodies 114 from being too small or even non-existent, which would cause the loading mechanism 500 to interfere with the other frame body 114 when stacking and loading one frame body 114. This facilitates the stacking and loading of the board unit 21. After the loading is completed, the conveying mechanism 210 first drives the two frame bodies 114 to close, and then simultaneously drives the two frame bodies 114 to move forward to the strapping station, so as to facilitate the transportation, strapping and unloading of the board unit 21, and to facilitate the subsequent buffering of the carrier frame 110.

[0076] In this embodiment, the specific structure of the third conveying component 212 is the same as that of the first conveying component 2212 or the second conveying component 2214, and will not be described again here.

[0077] The first clamping assembly 213 includes a third driving member 2131, a roller plate 2132, a fourth driving member 2133, and a limiting clamping plate 2134. The third driving member 2131 is connected to the roller plate 2132, and the fourth driving member 2133 is connected to the limiting clamping plate 2134. The third driving member 2131 and the fourth driving member 2133 are disposed opposite to each other on both sides of the third conveying assembly 212. The third driving member 2131 is used to drive the roller plate 2132 closer to the limiting clamping plate 2134, and the fourth driving member 2133 is used to drive the limiting clamping plate 2134 closer to the roller plate 2132, so that the support frame 110 is clamped between the roller plate 2132 and the limiting clamping plate 2134. Specifically, during the clamping process of the support frame 110, the third driving member 2131 and the fourth driving member 2133 work together to synchronously drive the roller plate 2132 and the limiting clamping plate 2134 to move closer to each other. During this process, the support frame 110 is embedded in the limiting clamping plate 2134. The limiting clamping plate 2134 is used to limit the support plate in the vertical direction, and the roller plate 2132 and the limiting clamping plate 2134 are used together to limit the support plate in the horizontal direction.

[0078] In this embodiment, the first driving component 22121 and the second driving component 22142 are both electric motors, pneumatic motors or hydraulic motors, and the third driving component 2131 and the fourth driving component 2133 are both electric cylinders, pneumatic cylinders or hydraulic cylinders.

[0079] Please continue to refer to Figure 1 and Figure 2Optionally, the palletizing system 10 also includes a storage mechanism 600, a destacking mechanism 700, and multiple trays 800. A feeding mechanism 400 is disposed between the storage mechanism 600 and the conveying device 200. Multiple trays 800 are overlapped within the destacking mechanism 700. The destacking mechanism 700 is used to deliver the trays 800 to the feeding mechanism 400. The feeding mechanism 400 is used to rotate the board unit group and load it onto the tray 800. The feeding mechanism 400 is also used to deliver the trays 800 containing the board unit group to the storage mechanism 600, thereby realizing the feeding function of the board unit group.

[0080] Please refer to Figure 14 Furthermore, the feeding mechanism 400 includes a base 410, a tilting assembly 420, a tilting frame 430, a fourth conveying assembly 440, and a fifth conveying assembly 450. The tilting assembly 420 is mounted on the base 410 and connected to the tilting frame 430. The tilting assembly 420 is used to drive the tilting frame 430 to rotate relative to the base 410. Specifically, the flipping frame 430 includes a first frame 431 and a second frame 432 that are perpendicular to and connected to each other. A fourth conveying component 440 is installed on the first frame 431, and a fifth conveying component 450 is installed on the second frame 432. During the flipping process, the flipping frame 430 can synchronously drive the fourth conveying component 440 and the fifth conveying component 450 to rotate. The fourth conveying component 440 is used to connect the support frame 110 containing the board unit group to the first frame 431. The flipping component 420 is used to drive the flipping frame 430 to rotate 90 degrees so that the board unit group is supported on the bracket 800 located on the second frame 432. The fifth conveying component 450 is used to send the bracket 800 containing the board unit group to the stacking mechanism 600. The destacking mechanism 700 is used to send the bracket 800 to the second frame 432. The flipping component 420 is used to drive the flipping frame 430 to rotate 90 degrees. The fourth conveying component 440 is also used to send the support frame 110 back to the conveying device 200.

[0081] In this embodiment, the specific structures of the fourth conveying component 440 and the fifth conveying component 450 are the same as those of the first conveying component 2212 or the second conveying component 2214, and will not be described again here.

[0082] Optionally, the unloading mechanism 400 further includes a second clamping assembly 460 and a third clamping assembly 470. The second clamping assembly 460 is mounted on the first frame 431 and is used to clamp and fix the support frame 110 to prevent displacement of the support frame 110 during the flipping process. The third clamping assembly 470 is mounted on the second frame 432 and is used to clamp and fix the bracket 800 to prevent displacement of the bracket 800 during the flipping process.

[0083] In this embodiment, the flipping component 420, the second clamping component 460, and the third clamping component 470 are all driven by electric cylinders. However, this is not the only embodiment. In other embodiments, the flipping component 420, the second clamping component 460, and the third clamping component 470 may also be driven by pneumatic cylinders or hydraulic cylinders.

[0084] Specifically, during the unloading process of the unloading mechanism 400, the first transfer section 221 of the transfer buffer mechanism 220 first delivers the carrier frame 110 containing the sheet metal unit group to the fourth conveying assembly 440 installed on the first frame 431; then the second clamping assembly 460 clamps and fixes the carrier frame 110; next, the flipping assembly 420 drives the flipping frame 430 to rotate 90 degrees so that the sheet metal unit group is supported on the bracket 800 located on the second frame 432. During this process, the carrier frame 110 remains stationary under the clamping action of the second clamping assembly 460; then the fifth conveying assembly 450 installed on the second frame 432 delivers the sheet metal unit group... The empty tray 800 is sent to the storage mechanism 600 for storage, awaiting the next process; then the destacking mechanism 700 removes an empty tray 800 and sends it to the second frame 432; then the third clamping assembly 470 clamps and fixes the tray 800; then the flipping assembly 420 drives the flipping frame 430 to rotate 90 degrees. During this process, the carrier frame 110 remains stationary under the clamping action of the second clamping assembly 460, and the tray 800 remains stationary under the clamping action of the third clamping assembly 470; then the second clamping assembly 460 releases the carrier frame 110, and then the fourth conveying assembly 440 sends the empty carrier frame 110 back to the first transfer section 221.

[0085] This invention also provides a palletizing method, which is applied to the above-mentioned palletizing system. The palletizing method includes the following steps: Step S110: Use the feeding mechanism 500 to feed multiple sheet metal units 21 onto the support frame 110 located at the feeding station.

[0086] It should be noted that in step S110, the conveying mechanism 210 of the conveying device 200 first drives the two frame bodies 114 of the bearing frame 110 to separate to a preset distance at the loading station; then the loading mechanism 500 uses the multiple plate units 21 to clamp and stack them onto the two frame bodies 114 in sequence to realize the loading function.

[0087] Step S120: The carrier frame 110 containing multiple sheet metal units 21 is transported from the loading station to the strapping station using the conveyor device 200.

[0088] It should be noted that in step S120, the two frame bodies 114 of the support frame 110 are first driven to close by the conveying mechanism 210; then the support frame 110 and the multiple plate units 21 stacked on it are driven to move from the loading station to the strapping station by the conveying mechanism 210.

[0089] Step S130: Use the strapping mechanism 300 to strap multiple board units 21 on the support frame 110 to form a board unit group.

[0090] It should be noted that in step S130, the strapping mechanism 300 is used to strap multiple board units 21 at the strapping station to form a board unit group and realize the strapping function.

[0091] Step S140: The carrier frame 110 containing the sheet metal unit group is sent from the strapping station to the unloading mechanism 400 using the conveyor device 200.

[0092] It should be noted that in step S140, the conveying mechanism 210 of the conveying device 200 first sends the carrier frame 110 containing the board unit group from the strapping station to the first transfer section 221 of the reciprocating buffer section 222; then the first transfer section 221 sends the carrier frame 110 containing the board unit group to the unloading mechanism 400.

[0093] Step S150: The sheet metal unit group is fed out by the feeding mechanism 400 through the support frame 110.

[0094] It should be noted that in step S150, the unloading mechanism 400 firstly drives the support frame 110 and the board unit group to rotate 90 degrees simultaneously, so that the board unit group is supported on the bracket 800; then the unloading mechanism 400 sends the bracket 800 containing the board unit group to the stacking mechanism 600 for storage, so as to realize the unloading function; then the unstacking mechanism 700 removes an empty bracket 800 and sends it to the unloading mechanism 400; then the unloading mechanism 400 drives the empty support frame 110 and the empty bracket 800 to rotate 90 degrees; then the unloading mechanism 400 sends the empty support frame 110 back to the first transfer section 221.

[0095] The palletizing system provided in this invention features a conveying device and a feeding mechanism arranged adjacent to each other. The conveying device includes a loading station, a strapping station, and a buffer station. The conveying device transports a carrier frame containing multiple sheet metal units from the loading station to the strapping station. The strapping mechanism straps the multiple sheet metal units on the carrier frame at the strapping station to form sheet metal unit groups. The conveying device also transports the carrier frame containing the sheet metal unit groups from the strapping station to the feeding mechanism. The feeding mechanism unloads the sheet metal unit groups from the carrier frame and returns the carrier frame to the conveying device. The conveying device also buffers other carrier frames at the buffer station. Compared with existing technologies, the palletizing system provided by this invention, due to the use of a conveying device with a loading station, strapping station, and buffer station, and a feeding mechanism arranged adjacent to the conveying device, can achieve automated conveying, strapping, and unloading of sheet metal units, effectively shortening the palletizing cycle, improving palletizing efficiency, saving labor and time costs, and increasing economic benefits. This makes the palletizing method simple, efficient, and effective.

[0096] Second Embodiment Please refer to Figure 15 This embodiment of the invention provides a palletizing system 10. Compared with the first embodiment, the difference in this embodiment lies in the different structure of the transfer buffer mechanism 220.

[0097] In this embodiment, the transfer and buffer mechanism 220 includes a second transfer section 223 and a circulating buffer section 224, with the buffer station located in the circulating buffer section 224. The conveying mechanism 210, the second transfer section 223, and the unloading mechanism 400 are arranged sequentially. One end of the circulating buffer section 224 is adjacent to the loading station, and the other end is adjacent to the second transfer section 223. The second transfer section 223 is used to transport the carrier frame 110 containing the board unit group from the conveying mechanism 210 to the unloading mechanism 400. The second transfer section 223 is also used to transport the carrier frame 110 returned from the unloading mechanism 400 to the circulating buffer section 224. The circulating buffer section 224 is used to buffer the carrier frame 110 and also to transport the carrier frame 110 to the loading station. Specifically, through the cyclically configured conveying mechanism 210, second transfer section 223, and cyclic buffer section 224, the carrier frame 110 can be reused repeatedly, facilitating the automated conveying, strapping, and unloading of the sheet metal unit 21, effectively shortening the strapping and palletizing cycle, improving strapping and palletizing efficiency, saving labor and time costs, and improving economic benefits.

[0098] Furthermore, the conveying mechanism 210, the second transfer section 223, and the circulating buffer section 224 are connected end to end to facilitate the cyclical reuse of the support frame 110. Specifically, the conveying mechanism 210, the second transfer section 223, and the circulating buffer section 224 together form a rectangle, triangle, trapezoid, or other shape, and there is no specific limitation on the shape formed by the conveying mechanism 210, the second transfer section 223, and the circulating buffer section 224.

[0099] In this embodiment, the conveying mechanism 210, the second transfer section 223, and the circulating buffer section 224 together form a rectangle. The circulating buffer section 224 includes a first buffer segment 2241, a second buffer segment 2242, and a third buffer segment 2243 connected in sequence. The first buffer segment 2241 and the third buffer segment 2243 are arranged opposite to each other at both ends of the second buffer segment 2242 and are both perpendicular to the second buffer segment 2242. The first buffer segment 2241 is adjacent to the second transfer section 223, and the third buffer segment 2243 is adjacent to the loading station. Specifically, the conveying mechanism 210 is used to send the carrier frame 110 to the second transfer section 223, the second transfer section 223 is used to send the carrier frame 110 to the first buffer section 2241, the first buffer section 2241 is used to send the carrier frame 110 to the second buffer section 2242, the second buffer section 2242 is used to send the carrier frame 110 to the third buffer section 2243, and the third buffer section 2243 is used to send the carrier frame 110 back to the loading station of the conveying mechanism 210, so as to realize the cyclic conveying of the carrier frame 110.

[0100] In this embodiment, the specific structure of the second transfer section 223 is the same as that of the first transfer section 221, and will not be described again here.

[0101] In this embodiment, the circulating buffer section 224 drives the support frame 110 to move through roller transmission, but it is not limited to this. In other embodiments, the circulating buffer section 224 can also drive the support frame 110 to move through belt transmission or chain plate transmission. The transmission form of the circulating buffer section 224 is not specifically limited.

[0102] In this embodiment, there is one feeding mechanism 500, one second transfer section 223, one circulating buffer section 224, one conveying mechanism 210, one strapping mechanism 300, and one unloading mechanism 400. The feeding mechanism 500 is arranged adjacent to the conveying mechanism 210. The feeding mechanism 500 is used to feed multiple board units 21 onto a support frame 110 located at the feeding station to realize the automatic stacking function of the strapping and palletizing system 10 and further improve the stacking and palletizing efficiency.

[0103] It should be noted that there are multiple support frames 110. During the operation of the stacking and palletizing system 10, the feeding mechanism 500 first places multiple sheet metal units 21 onto a support frame 110 located at the feeding station; then the conveying mechanism 210 transports the support frame 110 containing multiple sheet metal units 21 from the feeding station to the strapping station; next, the strapping mechanism 300 straps the multiple sheet metal units 21 on the support frame 110 at the strapping station to form sheet metal unit groups; then the conveying mechanism 210... The carrier frame 110 containing the sheet metal unit group is sent from the strapping station to the second transfer section 223; then the second transfer section 223 sends the carrier frame 110 containing the sheet metal unit group to the unloading mechanism 400; then the unloading mechanism 400 unloads the sheet metal unit group through the carrier frame 110; after unloading, the unloading mechanism 400 sends the empty carrier frame 110 back to the second transfer section 223; then the second transfer section 223 sends the empty carrier frame 110 to the circulation buffer section 224, where it is buffered. While the conveying mechanism 210 sends the carrier frame 110 containing multiple sheet metal units 21 from the loading station to the strapping station, the circulation buffer section 224 simultaneously sends an empty carrier frame 110 to the loading station, so that the loading mechanism 500 can immediately place the sheet metal unit 21 on the next carrier frame 110, thereby ensuring that the loading mechanism 500 is always in operation, shortening the strapping and stacking cycle, and improving the strapping and stacking efficiency.

[0104] The beneficial effects of the palletizing system 10 provided in this embodiment of the invention are the same as those in the first embodiment, and will not be repeated here.

[0105] Third Embodiment Please refer to the reference. Figure 16 and Figure 17 This embodiment of the invention provides a palletizing system 10. Compared with the first embodiment, the difference in this embodiment lies in the different structure of the transfer buffer mechanism 220.

[0106] In this embodiment, the transfer buffer mechanism 220 includes an independent buffer section 225, and the buffer station is disposed in the independent buffer section 225. The independent buffer section 225 is disposed at the end of the conveying mechanism 210 away from the unloading mechanism 400. The conveying mechanism 210 is used to send the carrier 110 returned from the unloading mechanism 400 to the independent buffer section 225, and the independent buffer section 225 is used to buffer the carrier 110. However, it is not limited to this. In other embodiments, the independent buffer section 225 may also be disposed on one side of the conveying mechanism 210, or in other locations of the conveying mechanism 210. The specific location of the independent buffer section 225 is not limited.

[0107] In this embodiment, the independent buffer section 225 drives the support frame 110 to move through roller transmission, but it is not limited to this. In other embodiments, the independent buffer section 225 can also drive the support frame 110 to move through belt transmission or chain plate transmission. The transmission form of the independent buffer section 225 is not specifically limited.

[0108] It should be noted that the palletizing system 10 also includes a gantry palletizing mechanism 900 and a conveyor 1000. The gantry palletizing mechanism 900 has multiple palletizing stations. It is used to place multiple sheet metal units 21 onto a support frame 110 located at each palletizing station. The conveyor 1000 is used to transport the support frame 110 containing multiple sheet metal units 21 from the palletizing station to the loading station of the conveyor mechanism 210. The conveyor 1000 is also used to return the support frame 110 located at the buffer station to an empty palletizing station. Specifically, by using the conveyor 1000, which moves flexibly between the gantry palletizing mechanism 900, the conveyor mechanism 210, and the independent buffer section 225, automated palletizing, conveying, strapping, and unloading of the sheet metal units 21 can be achieved, effectively shortening the palletizing cycle, improving palletizing efficiency, saving labor and time costs, and increasing economic benefits.

[0109] The gantry palletizing mechanism 900 includes a gantry frame 910, a palletizing robot 920, and multiple palletizing wire frames 930. All multiple palletizing wire frames 930 are housed within the gantry frame 910, with one palletizing wire frame 930 for each palletizing station. The palletizing robot 920 is movably mounted on the gantry frame 910 and is used to stack multiple sheet metal units 21 onto the support frame 110 located on the palletizing wire frame 930. The palletizing wire frame 930 is used to transport the support frame 110 containing the multiple sheet metal units 21 to the conveyor carrier 1000. Specifically, since there are multiple palletizing frames 930, the palletizing robot 920 can immediately palletize and load the carrier frame 110 on the next palletizing frame 930 after completing the palletizing and loading of the carrier frame 110 on one palletizing frame 930, thereby ensuring that the palletizing robot 920 is always in operation, shortening the palletizing cycle and improving the palletizing efficiency.

[0110] In this embodiment, the specific structure of the palletizing wire frame 930 is the same as that of the conveying mechanism 210, and will not be described again here. Specifically, the palletizing wire frame 930 can also realize the separation and closing functions of the two frame bodies 114 in the bearing frame 110, thereby facilitating the palletizing, loading and transportation of the board unit 21.

[0111] In this embodiment, the conveying carrier 1000 is an AGV. The conveying carrier 1000 is used to transport the carrier frame 110 on the palletizing frame 930 and the multiple plate units 21 stacked on the carrier frame 110 to the loading station of the conveying mechanism 210. The conveying carrier 1000 is also used to transport the empty carrier frame 110 on the independent buffer section 225 to the empty palletizing frame 930.

[0112] In this embodiment, multiple palletizing wire frames 930 are arranged side by side, and the conveying direction of the palletizing wire frames 930 is perpendicular to the side-by-side direction of the multiple palletizing wire frames 930, so as to achieve a reasonable and compact layout of multiple palletizing wire frames 930, save the floor space of the gantry palletizing mechanism 900, and avoid interference between adjacent palletizing wire frames 930 during palletizing and loading and the movement of the support frame 110, thereby improving reliability.

[0113] Optionally, the gantry palletizing mechanism 900 also includes a feeding line frame 940. The feeding line frame 940 extends into the gantry frame 910 and is used to sequentially feed multiple board units 21 into the gantry frame 910. The palletizing robot 920 is used to clamp the board units 21 on the feeding line frame 940 onto the support frame 110 located on the palletizing line frame 930, so as to realize the automated and rapid feeding of the board units 21, thereby facilitating the palletizing robot 920 to palletize and load the board units 21, and further improving the efficiency of bundling and palletizing.

[0114] In this embodiment, the gantry palletizing mechanism 900, the independent buffer section 225, the conveying mechanism 210, and the unloading mechanism 400 are arranged in a straight line to achieve a reasonable and compact layout of the entire palletizing system 10, saving the floor space occupied by the palletizing system 10. However, this is not the only embodiment. In other embodiments, the independent buffer section 225, the conveying mechanism 210, and the unloading mechanism 400 are arranged in a straight line, with the gantry palletizing mechanism 900 arranged side by side with its overall structure. The specific arrangement of the gantry palletizing mechanism 900, the independent buffer section 225, the conveying mechanism 210, and the unloading mechanism 400 is not specifically limited.

[0115] Optionally, the strapping and palletizing system 10 also includes a strapping mechanism 1100. The strapping mechanism 1100 is located at the end of the storage and stacking mechanism 600 away from the unloading mechanism 400. The storage and stacking mechanism 600 is used to deliver the bracket 800 containing the board unit group to the strapping mechanism 1100. The strapping mechanism 1100 is used to strap the bracket 800 and the board unit group on it to form a bracket board stack. The strapping mechanism 1100 is also used to drive the bracket board stack to unload, so as to facilitate the next process.

[0116] It should be noted that the number of support frames 110 is one more than the number of palletizing frames 930. During the operation of the palletizing system 10, the feeding frame 940 first feeds multiple sheet metal units 21 sequentially into the gantry frame 910 of the gantry palletizing mechanism 900; then, the palletizing robot 920 clamps the sheet metal units 21 on the feeding frame 940 onto the support frame 110 located on the palletizing frame 930 to realize the palletizing and loading function; next, the palletizing frame 930 sends the support frame 110 containing multiple sheet metal units 21 to the conveyor carrier 1000; then, the conveyor carrier 1000 sends the support frame 110 containing multiple sheet metal units 21 to the loading station of the conveying mechanism 210; then, the conveying mechanism 210 loads the support frame 110 containing multiple sheet metal units 21... The support frame 110 of the board unit 21 is sent from the loading station to the strapping station; then the strapping mechanism 300 straps multiple board units 21 on the support frame 110 at the strapping station to form a board unit group; then the conveying mechanism 210 sends the support frame 110 containing the board unit group from the strapping station to the unloading mechanism 400; then the unloading mechanism 400 unloads the board unit group through the support frame 110 to the stacking mechanism 600; then the stacking mechanism 600 sends the bracket 800 containing the board unit group to the strapping mechanism 1100; then the strapping mechanism 1100 straps the bracket 800 and the board unit group on it to form a bracket board stack group; then the strapping mechanism 1100 drives the bracket board stack group to unload. After the unloading mechanism 400 finishes unloading the board unit group, the unloading mechanism 400 sends the empty support frame 110 back to the conveying mechanism 210. Then the conveying mechanism 210 sends the empty support frame 110 to the independent buffer section 225. After that, the conveying carrier 1000 sends the empty support frame 110 back to the empty stacking wire frame 930, so as to realize the recycling of the support frame 110 and improve the efficiency of bundling and stacking.

[0117] The beneficial effects of the palletizing system 10 provided in this embodiment of the invention are the same as those in the first embodiment, and will not be repeated here.

[0118] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
