[0002] In aerated brick production lines, finished products need to be packaged as they leave the line. Currently, there are three packaging methods for finished products in aerated brick factories: manual loading and unloading, palletized packaging lines, and palletless packaging. Manual loading and unloading requires long periods of frequent physical activity, and due to the dirty, dangerous, and intense work environment, there is a growing labor shortage. Palletized packaging lines require a large number of pallets, and pallets on project sites are often lost, damaged, or rusted, rendering them unusable, resulting in high costs.

[0042] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0043] Four embodiments of the baling line are described below:

[0044] Example 1

[0045] like Figures 1 to 3 As shown, the packaging line provided by this embodiment includes: a first conveying part 10, a transfer device 20 and a stacking device 30. The first conveying part 10 is suitable for conveying blocks along a first preset direction. A lifting platform is provided at the tail end of the first conveying part 10. The lifting platform can be raised and lowered relative to the first conveying part 10 and is suitable for driving the blocks to rise and fall, and the lifting platform is suitable for stacking the blocks; the transfer device 20 is provided at the tail end of the first conveying part 10. The transfer device 20 is suitable for clamping multiple stacks of blocks after stacking and can selectively transfer multiple layers of blocks; the stacking device 30 is provided on one side of the first conveying part 10. The stacking device 30 is suitable for clamping blocks. The transfer device 20 and the stacking device 30 are suitable for stacking blocks at the stacking position 62 according to a preset arrangement rule to form a block stack; wherein the stacking device 30 is suitable for stacking the stacking bottom layer 71 and the transport layer 72 of the block stack, and the transfer device 20 is suitable for stacking multiple layers of blocks located above the transport layer 72 of the block stack. Among them, the first conveying part 10 is a conveying line, the first preset direction is the forward direction of the first conveying part 10; the tail of the first conveying part 10 is the end of the first conveying part 10 along the forward direction; the block stack contains multiple blocks, and the preset arrangement rules are the pre-determined number and placement direction of the blocks.

[0046] The packaging line of the present embodiment is applied, by setting a lifting platform relative to the first conveying part 10 at the tail end of the first conveying part 10, stacking blocks on the lifting platform, and using the transfer device 20 to stack the blocks stacked on the lifting platform, so as to achieve stacking and stacking of blocks at the same position. Compared with the traditional method that requires setting stacking position and stacking position separately, the packaging line of the present embodiment has a simple structure, compact layout and small space occupation; the transfer device 20 has the functions of stacking and transferring, further simplifies the structure and reduces the floor space of the overall device, and the transfer device 20 can transfer multiple layers of blocks at the same time, which greatly improves work efficiency compared with the traditional device that can only transfer single-layer blocks; through the cooperation of the first conveying part 10 with a lifting platform, the transfer device 20 and the stacking device 30, the blocks are stacked at the stacking position 62 according to the preset arrangement rules. The overall layout is simple and the operation is flexible, which is conducive to improving work efficiency.

[0047] It should be noted that the building blocks can be aerated concrete blocks and other blanks on an aerated concrete production line. During the production process, the blanks are placed on a base plate. After cutting, the blanks on the base plate are stacked. A stack of blanks contains multiple layers, and there is one blank on each layer. The upstream equipment conveys a stack of blanks to the first conveying part 10 at a preset time interval. The multiple stacks of blanks on the first conveying part 10 are spaced by a preset distance. The lifting platform has a stacking position 61. After the first conveying part 10 conveys a stack of blanks to the stacking position 61 of the lifting platform, the lifting platform rises. When the next stack of blanks is conveyed to the lifting platform and close to the previous stack of blanks, the first conveying part 10 stops, the lifting platform descends, and the two stacks of blanks continue to be conveyed forward on the conveyor chain. When all the blanks are conveyed to the lifting platform and the tail side of the blanks is aligned with the tail side of the lifting platform, the lifting platform rises and lifts the two stacks of blanks together. This cycle continues until the number of blanks on the lifting platform reaches the number of stacks. The first conveying part 10 includes a stacking position 61 along the conveyor chain. Figure 3 The two pairs of conveyor chains arranged side by side in the "width direction" indicated by the middle arrows follow the above logic. After the lifting platform is fully stacked with blanks, there is a certain gap between each stack of blanks. Then, the transfer device 20 is used to clamp the stacked multiple stacks of blocks to complete the stacking. The traditional stacking and stacking method is to use a transfer device such as a brick-holding robot to clamp multiple blocks to the stacking platform for stacking, and then transport them to the stacking platform and stack them using a movable plate at the stacking position. It is impossible to stack and stack at the same location. Not only is the structure complex, but it also occupies a large area, is costly and is not conducive to improving work efficiency. In addition, the blanks are easily damaged by friction during the stacking process.

[0048] In this embodiment, the transfer device 20 includes a block clamping machine 21 and a support frame 22. The block clamping machine 21 is movably arranged on the support frame 22. The block clamping machine 21 is suitable for stacking multiple blocks on the lifting platform. The block clamping machine 21 can selectively clamp multiple layers of blocks on the lifting platform and move relative to the support frame 22 to move the blocks from the first conveying part 10 to the stacking position 62, and / or the block clamping machine 21 can selectively clamp multiple layers of blocks on the lifting platform and drive the blocks to rotate in the horizontal plane to adjust the placement direction of the blocks at the stacking position 62. Figure 1 As shown, the support frame 22 is fixed on a fixed position such as the ground in the factory and is arranged across the first conveyor 10. The clamping machine 21 is movably arranged on the support frame 22. The clamping machine 21 is also located above the first conveyor 10 and the second conveyor 40. The clamping machine 21 reaches different working positions by moving on the support frame 22, which is convenient for clamping blocks from the first conveyor 10. When the transfer device 20 needs to transfer blocks, the clamping machine 21 clamps the multi-layer blocks on the lifting platform and moves relative to the support frame 22 until the blocks are transported to the stacking position 62 and then put down the blocks. The transfer process is simple, fast and easy to operate. Among them, the top refers to Figure 1 The arrow in the middle indicates the "up" direction; the moving direction of the clamping machine 21 on the support frame 22 is the same as the first preset direction.

[0049] In this embodiment, the blank clamping machine 21 is a rotary blank clamping machine, which is suitable for driving the blocks to rotate in the horizontal plane, thereby adjusting the placement direction of the blocks to meet the requirements of the preset arrangement rules. The blank clamping machine 21 can be used to rotate the blocks during the block transport process, which is convenient to operate and saves time. Specifically, the blank clamping machine 21 includes a traveling frame, a rotating portion, and a blank clamping portion. The traveling frame is movably mounted on the support frame 22, the rotating portion is rotatably mounted on the traveling frame, and the blank clamping portion is mounted on the rotating portion. The blank clamping portion is suitable for clamping the blank.

[0050] In this embodiment, the packaging line further includes a temporary storage platform 31, which is provided on one side of the palletizing device 30. The temporary storage platform 31 is suitable for temporarily storing the blocks in the process of being transferred. It should be noted that, during the process of transferring the blocks from the stacking position 61 to the palletizing position 62 for palletizing, there may be a situation where the number of blocks in a certain layer at the palletizing position 62 is less than the number of blocks in a layer at the palletizing position 61. The excess blocks are temporarily stored on the temporary storage platform 31 to ensure that the subsequent blocks can be transferred from the palletizing position 61 to the palletizing position 62 in a whole layer, thereby ensuring the smooth progress of the stacking work and improving work efficiency.

[0051] In this embodiment, the packaging line also includes a second conveyor section 40, which is disposed downstream of the first conveyor section 10. The head of the second conveyor section 40 forms a stacking position 62, and the second conveyor section 40 is suitable for transporting the stack of blocks along a second predetermined direction. The blocks are stacked at the stacking position 62 on the second conveyor section 40 by the transfer device 20 and the stacking device 30. The stacking position 62 is located directly on the second conveyor section 40. Therefore, the stack of blocks stacked at the stacking position 62 can be directly transported by the second conveyor section 40 without further transfer, thus saving space, achieving a compact layout, and improving work efficiency. The second conveyor section 40 is a conveyor line, and the second predetermined direction is the forward direction of the second conveyor section 40. The head of the second conveyor section 40 is its end near the first conveyor section 10.

[0052] In this embodiment, a support member 41 is fixedly mounted on the second conveyor section 40. The support member 41 is suitable for supporting the stack of blocks. The support member 41 functions like a pallet in a palletized packaging line, preventing the bottom blocks of the stack from directly contacting the second conveyor section 40. This reduces friction and wear, ensures the integrity of the stack, and improves product quality. Preferably, the support member 41 is a crossbeam sleeper, which spans the second conveyor section 40. Multiple crossbeam sleepers are spaced apart and collectively support a stack of blocks, providing excellent stability and saving materials. It is understood that, as an alternative embodiment, the support member 41 may also be a support plate, which has a large support area and excellent stability.

[0053] In this embodiment, the first conveying part 10 and the second conveying part 40 are arranged in a "one" shape. The "one" shape arrangement is more common and is convenient for arrangement. The first preset direction is the same as the second preset direction. The head of the second conveying part 40 is connected to the tail of the first conveying part 10. The transport distance of the blocks from the stacking position 61 to the stacking position 62 is short, which is convenient for operation. The temporary storage platform 31 is set on the side of the second conveying part 40 to temporarily store the excess blocks during the transport process. Among them, the side of the second conveying part 40 refers to the side along Figure 3 One of the two sides in the "width direction" indicated by the arrow in the middle. Specifically, the temporary storage platform 31 includes a first temporary storage platform 311 and a second temporary storage platform 312, which are arranged on the same side of the second conveying portion 40. Excess building blocks during the transfer process are temporarily stored on the first temporary storage platform 311 or the second temporary storage platform 312. It is understood that as an alternative embodiment, the temporary storage platform 31 may also include only the first temporary storage platform 311, which can also achieve the function of temporarily storing excess building blocks during the transfer process.

[0054] In this embodiment, the packing line further includes a packing device, which is disposed at the second conveying portion 40 and is suitable for packing a stack of blocks. It should be noted that after the blocks are stacked at the stacking position 62 by the transfer device 20 and the stacking device 30 to form a stack of blocks, the packing device is required to pack the stack of blocks to prevent the stack of blocks from becoming loose, thereby facilitating subsequent transportation of the stack of blocks.

[0055] Preferably, the packing device is a baler, which is widely used and highly efficient. The baler includes a horizontal baler 51 and a through-arrow baler 52. The horizontal baler 51 is used to wrap a horizontal fixing wire 81 around the stack of blocks, while the through-arrow baler 52 is used to wrap a through-arrow fixing wire 82 around the stack of blocks. The through-arrow fixing wire 82 intersects the horizontal fixing wire 81 perpendicularly, thereby firmly securing the stack of blocks. The baler can also be arranged to perform both horizontal and vertical through-arrow packing. The support member 41 on the second conveyor 40 is designed to be compatible.

[0056] In this embodiment, the stacking device 30 is a robot, which is widely used, highly flexible and easy to operate. The robot is suitable for stacking the stacking bottom layer 71 and the transport layer 72 of the block stack. The transfer device 20 is suitable for stacking the multi-layer blocks located above the transport layer. The transfer device 20 simultaneously clamps the multi-layer blocks, thereby improving work efficiency and speeding up production. It should be noted that, if Figures 7 to 15 As shown, the block stack is formed by stacking multiple layers of blocks, specifically including the bottom stacking layer 71, the transport layer 72 adjacent to the stacking layer 71, and multiple layers of blocks located above the transport layer 72. The number of blocks in the transport layer 72 is less than that in the stacking layer 71, that is, the blocks in the transport layer 72 cannot cover the entire layer. Space is left between the blocks to facilitate the insertion of the transport device to transport the block stack. The bottom refers to the bottom along the stacking layer. Figure 1 Preferably, the transporting device is a forklift, the forklift arm of which extends into the clearance space of the transport layer 72 of the block stack to transport the packed block stack.

[0057] It should be noted that the building blocks are rectangular parallelepipeds, and the length direction of the building blocks on the first conveying part 10 is perpendicular to the first preset direction, that is, perpendicular to the first preset direction. Figure 3 The width direction indicated by the arrow in the middle is parallel, and when the block stack is located at the second conveying part 40, in order to facilitate the insertion of the handling device into the clearance space of the block stack to transport the block stack, the opening of the clearance space is usually directed toward the side of the second conveying part 40, combined with Figures 7 to 15From the stacking rules of the block stack shown, it can be seen that except for the blocks in the transport layer 72, the length directions of the blocks in other layers of the block stack are parallel to the second preset direction. Therefore, when using the clamping machine 21 to transfer the multiple layers of blocks on the lifting platform, it is also necessary to drive the blocks to rotate 90° so that when the blocks reach the stacking position 62, the length directions of the blocks are parallel to the second preset direction.

[0058] Example 2

[0059] like Figure 4 As shown, the difference between the packaging line of the second embodiment and the first embodiment is that the temporary storage platform 31 is set at a different position. In the second embodiment, the temporary storage platform 31 is set between the first conveying part 10 and the second conveying part 40. Specifically, the first temporary storage platform 311 is located between the tail of the first conveying part 10 and the head of the second conveying part 40. The second temporary storage platform 312 is set corresponding to the first temporary storage platform 311 and is located on the side of the first temporary storage platform 311. The stacking device 30 is set on the side of the second conveying part 40, wherein the side of the first temporary storage platform 311 refers to the side along the Figure 4 One of the two sides in the “width direction” indicated by the middle arrow is the side where the palletizing device 30 is provided, so that the palletizing device 30 can transfer the excess building blocks to the second temporary storage platform 312 .

[0060] It should be noted that, since the first temporary storage platform 311 is located between the first conveying part 10 and the second conveying part 40, and the support frame 22 of the transfer device 20 is arranged above the first conveying part 10 and the second conveying part 40, the transfer device 20 can transfer a whole stack of building blocks at the stacking position 61 to the first temporary storage platform 311, and then the stacking device 30 clamps the building blocks from the first temporary storage platform 311 and stacks the stacking bottom layer 71 and the transport layer 72 at the stacking position 62. Moreover, after the transfer device 20 transfers the whole stack of building blocks at the stacking position 61 to the first temporary storage platform 311, a new whole stack of building blocks is formed at the stacking position 61. At this time, the transfer device 20 can transfer the newly formed building block stack at the stacking position 61 as a whole to the transport layer 72 at the stacking position 62, thereby forming a building block stack. Since the number of layers in the height direction of the block stack at the stacking position 61 is constant, the block stack stacked using the baling line of the second embodiment has two more layers of blocks than the block stack stacked using the baling line of the first embodiment.

[0061] Example 3

[0062] like Figure 5As shown, the difference between the baling line of Example 3 and Example 1 is that the arrangement of the first conveying part 10 and the second conveying part 40 is different. In Example 3, the first conveying part 10 and the second conveying part 40 are arranged vertically, and the temporary storage platform 31 is arranged on the side of the second conveying part 40 away from the first conveying part 10. The first preset direction is perpendicular to the second preset direction. Compared with the baling line of Example 1, the baling line of Example 3 has a shorter length but a larger width. It is suitable for environmental conditions when the length of the factory space is less than the length of the "I"-shaped arrangement. The overall structure is compact and has good adaptability.

[0063] It should be noted that, since the first preset direction is perpendicular to the second preset direction, when using the clamping machine 21 to transfer the building blocks, there is no need to rotate the building blocks, and the length direction of the building blocks is already parallel to the second preset direction; and when using the stacking device 30 to stack the transport layer 72, it is necessary to rotate the building blocks clamped from the stacking position 61 90° so that the building blocks in the transport layer 72 are perpendicular to the second preset direction to comply with the stacking rules.

[0064] Example 4

[0065] like Figure 6 As shown, the difference between the packaging line of the fourth embodiment and the third embodiment is whether a transfer conveyor line is set. In the fourth embodiment, the packaging line also includes a transfer conveyor line 90, which is arranged on the side of the second conveying part 40 away from the first conveying part 10. The temporary storage platform 31 is provided with one and is arranged on one side of the tail of the transfer conveyor line 90. The head of the transfer conveyor line 90 extends into the support frame 22 and is arranged corresponding to the tail of the first conveying part 10. The stacking position includes a first stacking position 621 and a second stacking position 622, wherein the stacking device 30 and the first stacking position 621 are respectively provided at the first stacking position 622 and the second stacking position 622. The tail ends of the two conveying parts 40 are adjacent to each other, the temporary storage platform 31 and the transfer conveyor line 90 are arranged in sequence along the second preset direction, the tail end of the transfer conveyor line 90 is adjacent to the temporary storage platform 31, the first stacking position 621 and the second stacking position 622 are arranged in sequence along the second preset direction, and the second stacking position 622 is adjacent to the tail end of the first conveying part 10, the stacking position 61 and the second stacking position 622 are arranged in sequence along the first preset direction, and the transfer device 20 is arranged across the stacking position 61, the second stacking position 622 and the head of the transfer conveyor line 90.

[0066] Specifically, a whole stack of blocks transferred from the stacking position 61 by the transfer device 20 is placed on the transfer conveyor line 90. The transfer conveyor line 90 transports the whole stack of blocks in a direction opposite to the second preset direction. The stacking device 30 grabs blocks from the tail of the transfer conveyor line 90 and stacks them on the first stacking position 621, stacking the stacking bottom layer 71 and the transport layer 72. The remaining blocks are placed on the temporary storage platform 31. The stacked stacking bottom layer 71 and the transport layer 72 are transported from the first stacking position 621 to the second stacking position 622 along the second preset direction. Then, the transfer device 20 can transfer the whole stack of blocks at the stacking position 61 to the transport layer 72 at the second stacking position 622, thereby forming a block stack. The above-mentioned layout can avoid interference between devices during operation. The block stack stacked by the packaging line of this embodiment has two more layers of blocks than the block stack stacked by the packaging line of Example 3.

[0067] Four embodiments of the packaging method are described below:

[0068] Example 1

[0069] In this embodiment, the packaging method uses the packaging line of the above-mentioned embodiment 1, and the packaging method includes the following steps: transporting the blocks to the lifting platform along the first preset direction by the first conveying part 10, and stacking the blocks on the lifting platform; stacking the stacked multi-layer blocks by the transfer device 20 to form a block pile; stacking the blocks at the stacking position 62 according to the preset arrangement rules by the transfer device 20 and the stacking device 30, stacking the stacking bottom layer 71 and the transport layer 72 by the stacking device 30, and stacking the multi-layer blocks above the transport layer 72 by the transfer device 20 to form a block stack. Stacking and stacking are both performed on the lifting platform, which saves the time of transferring from the stacking platform to the stacking platform and then stacking in the prior art, and has high work efficiency; at the same time, the transfer device can not only stack the blocks, but also transfer the blocks, and can also transfer multi-layer blocks at the same time, which significantly improves work efficiency. Among them, the lifting platform has a stacking position 61 and a waiting position 63. The waiting position 63 is located at the end of the stacking position 61 away from the second conveying part 40. The transfer device 20 is parked at the waiting position 63 when not clamping the building blocks to avoid interference between the devices and ensure the smooth progress of the work; the first conveying part 10 includes two parallel conveying lines, and the two conveying lines convey the building blocks at the same time. The building blocks on the two conveying lines can be combined by stacking.

[0070] In this embodiment, the packaging line also includes a temporary storage platform 31, which is arranged on one side of the stacking device 30, and the temporary storage platform 31 is suitable for temporarily storing blocks in the transportation process. The step of stacking blocks at the stacking position 62 according to the preset arrangement rules by the transfer device 20 and the stacking device 30 includes: the first and second layers from top to bottom of the block pile are transferred to the stacking position 62 by the stacking device 30, and stacked in sequence to form a stacking bottom layer 71 and a transport layer 72 of the block stack, and the remaining blocks in the second layer of the block stack are placed on the temporary storage platform 31; the multi-layer blocks at the lifting platform are transferred to the stacking position 62 by the transfer device 20 and stacked on the transport layer to form a block stack; wherein the blocks of the transport layer 72 are perpendicular to the blocks of the stacking bottom layer 71, and the multiple blocks of the transport layer 72 are placed at intervals, and the space between two adjacent blocks is suitable for inserting the transport device. The first layer and the second layer refer to the blocks along the stacking position 62. Figure 1 The first layer and the second layer from top to bottom in the "up and down" direction indicated by the middle arrow; all the blocks of the first layer in the block stack are transferred by the stacking device 30 to the stacking position 62 to form the stacking bottom layer 71, and some blocks of the second layer are transferred by the stacking device 30 to the stacking bottom layer 71 to form the transport layer 72, and the blocks in the second layer that are not used to form the transport layer 72 are placed on the temporary storage platform 31 by the stacking device 30.

[0071] Specifically, take the block with the size of 200×200×600mm as an example. Figures 7 to 15 As shown, the block stack comprises six layers. Each layer, excluding the transport layer, has two rows of blocks, each row having six blocks, for a total of 12 blocks per layer. The overall dimensions of the block stack are 1200 × 1200 × 1200 mm. Transport layer 72 comprises eight blocks, the length of which is perpendicular to the length of the blocks in the other layers. After a block layer is placed above transport layer 72, a clearance space is formed between transport layer 72 and the upper and lower block layers, extending through the entire block stack. This clearance space is suitable for inserting a transport device to transport the block stack.

[0072] In this embodiment, after the step of placing the remaining blocks in the second layer of the block stack on the temporary storage platform 31, the packaging method further includes: when the temporary storage platform 31 is full of at least one layer of blocks, the blocks are grabbed from the temporary storage platform 31 by the stacking device 30 and transported to the stacking position 62 to form a stacking bottom layer 71 or a transport layer 72, which can fully utilize the blocks on the temporary storage platform 31, save space and improve work efficiency. Specifically, when the number of blocks on the temporary storage platform 31 is greater than or equal to the number of blocks required for the palletizing bottom layer 71, and the palletizing bottom layer 71 needs to be stacked at the palletizing position 62, the palletizing device 30 grabs a layer of blocks from the temporary storage platform 31 and transfers it to the palletizing position 62 to form the palletizing bottom layer 71. When the number of blocks on the temporary storage platform 31 meets the number of blocks required for the transport layer 72, and the palletizing position 62 needs to stack the transport layer 72, the palletizing device 30 grabs the number of blocks required for the transport layer 72 from the temporary storage platform 31 and transfers it to the palletizing position 62 to form the transport layer 72. A layer of blocks refers to a layer of blocks with the same number of blocks as the stack, which is also equal to the number of blocks required for the palletizing bottom layer 71.

[0073] In this embodiment, the steps of transferring the first and second layers of the block stack from top to bottom to the stacking position 62 by the stacking device 30 and stacking them in sequence to form a stacking bottom layer 71 and a transport layer 72 of the block stack, and placing the remaining blocks in the second layer on the temporary storage platform 31 include: the stacking device 30 grabs all the blocks of the first layer from the lifting platform and transfers them to the stacking position 62 to form the stacking bottom layer 71, then the stacking device 30 grabs all the blocks of the second layer from the lifting platform and transfers them to the stacking bottom layer 71, and then the stacking device 30 grabs the remaining blocks in the second layer except the blocks stacked in the transport layer 72 and transfers them to the first temporary storage platform 311 or the second temporary storage platform 312. It should be noted that the stacking device 30 can transport one layer of building blocks at the same time. When stacking the stacking bottom layer 71, all the building blocks of one layer are required. The stacking device 30 transports the building blocks of one layer to the stacking position 62 at the same time. When stacking the transport layer 72, since the number of building blocks required is less than the number of building blocks of a whole layer on the lifting platform, and the building block stacking rules on the transport layer 72 are different from those of the stacking bottom layer 71, the stacking device 30 is required to first transfer all the building blocks of the second layer to the stacking bottom layer 71, and then clamp out the building blocks that are not used to construct the transport layer 72 (that is, the remaining building blocks except the building blocks stacked in the transport layer 72) and transfer them back to the first temporary storage platform 311 or the second temporary storage platform 312. The operation is flexible and the work efficiency is high.

[0074] In this embodiment, the temporary storage platform 31 includes a first temporary storage platform 311 and a second temporary storage platform 312. When the stacking device 30 grabs the second layer of blocks in the block pile to stack the transport layer 72, the remaining blocks in the second layer that are not used for stacking the transport layer 72 are transferred to the first temporary storage platform 311 or the second temporary storage platform 312. When the blocks on the first temporary storage platform 311 or the second temporary storage platform 312 are full of the number of blocks for one layer, and the stacking bottom layer 71 needs to be stacked on the stacking position 62, the stacking device 30 grabs a layer of blocks from the first temporary storage platform 311 or the second temporary storage platform 312 and transfers it to the stacking position 62 to form the stacking bottom layer 71. When the blocks on the first temporary storage platform 311 or the second temporary storage platform 312 need to be stacked, the stacking device 30 grabs a layer of blocks from the first temporary storage platform 311 or the second temporary storage platform 312 and transfers it to the stacking position 62 to form the stacking bottom layer 71. When transporting the layer 72, the palletizing device 30 grabs the building blocks from the first temporary storage platform 311 or the second temporary storage platform 312 and transfers them to the palletizing bottom layer 71 to form the transporting layer 72; or, when the building blocks on the first temporary storage platform 311 or the second temporary storage platform 312 are stacked with the number of two layers of building blocks, and the palletizing bottom layer 71 needs to be stacked on the palletizing position 62, the palletizing device 30 first grabs a layer of building blocks from the first temporary storage platform 311 or the second temporary storage platform 312 and transfers it to the palletizing position 62 to form the palletizing bottom layer 71, and then the palletizing device 30 grabs a layer of building blocks from the first temporary storage platform 311 or the second temporary storage platform 312 and transfers it to the palletizing bottom layer 71 to form the transporting layer 72.

[0075] In this embodiment, in the step of transferring the multi-layer building blocks at the lifting platform to the stacking position 62 together by the transfer device 20, the multi-layer building blocks after removing the first layer and the second layer from the block pile are transferred to the stacking position 62 together by the clamping machine 21. Transferring the multi-layer building blocks together can significantly improve the working efficiency.

[0076] In this embodiment, the baling line further includes a baling device disposed on the second conveyor portion 40. After the blocks are stacked at the stacking position 62 on the second conveyor portion 40 by the transfer device 20 and the stacking device 30, the baling method further includes baling the stack of blocks by the baling device. Specifically, baling the stack of blocks by the baling device includes wrapping a horizontal fixing wire 81 around the stack of blocks by the horizontal baler 51, and wrapping a through-arrow fixing wire 82 around the stack of blocks, perpendicularly intersecting the horizontal fixing wire 81, by the through-arrow baler 52, thereby securely securing the stack of blocks.

[0077] Taking a block with a size of 200×200×600 mm as an example, the block pile at stacking position 61 has 6 layers of blocks. The stacked block pile includes 6 layers of blocks, and the size of the block pile is 1200×1200×1200 mm. The specific steps of the packaging method are as follows:

[0078] The blocks are grouped and stacked on the lifting platform of the first conveying section 10, and the block clamping machine 21 stacks the blocks at the stacking position 61 and then stops at the waiting position 63. The stacking device 30 clamps the blocks from the stacking position 61 to the stacking position 62 and stacks them on the stacking bottom layer 71 and the transport layer 72. The excess blocks are placed on the first temporary storage platform 311 or the second temporary storage platform 312. The block clamping machine 21 rotates and clamps the remaining four layers of blocks at the stacking position 61 to the stacking position 62 to form a block stack. The block stack is transported by the second conveying section 40 to the packing machine for packing. The forklift picks up the block stack for transportation. When the blocks on the first temporary storage platform 311 or the second temporary storage platform 312 are stacked on one or two layers, the stacking device 30 grabs the blocks from the first temporary storage platform 311 or the second temporary storage platform 312 and stacks them on the stacking bottom layer 71 or the transport layer 72.

[0079] A specific step of palletizing is as follows:

[0080] 1) The building blocks are transported to the lifting platform along a first preset direction by the first conveying part 10, and the building blocks are lifted and lowered by the lifting platform, and the required number of building blocks are piled on the lifting platform.

[0081] 2) The clamping machine 21 stacks the blocks at the stacking position 61 → the clamping machine 21 is released → the clamping machine 21 moves to the waiting position 63 and waits.

[0082] 3) The palletizing device 30 initially stops at the first temporary storage platform 311 with its cantilever. The palletizing device 30 reaches the stacking position 61 and picks up the top two layers of blocks from the stack. It first picks up a whole layer of blocks from the first layer and rotates it to the stacking position 62 to form the stacking bottom layer 71. It then picks up a whole layer of blocks from the second layer and places it on the stacking bottom layer 71 to form the transport layer 72. The remaining blocks from the second layer are placed side by side on the first temporary storage platform 311. The palletizing device 30 stops at the first temporary storage platform 311 and waits.

[0083] 4) The clamping machine 21 moves from the waiting position 63 to the stacking position 61 and clamps the remaining 4 layers of blocks in the bottom of the block pile at the stacking position 61 → the clamping machine 21 drives the 4 layers of blocks to move and rotate and place them at the stacking position 62 → the clamping machine 21 returns to the stacking position 61 and waits.

[0084] 5) Repeat steps 1 → 2 → 3 → 4.

[0085] 6) When one stack of building blocks is completed at the stacking position 62 and two layers of building blocks are stacked at the first temporary storage platform 311 for the first time, the stacking device 30 first clamps a whole layer of building blocks at the first temporary storage platform 311, rotates it and places it at the stacking position 62 to stack the stacking bottom layer 71, then clamps the remaining whole layer of building blocks and places it at the stacking position 62 to stack the transport layer 72, and places the excess building blocks again on the first temporary storage platform 311 side by side → the stacking device 30 stops at the first temporary storage platform 311 and waits.

[0086] 7) The lifting platform of the first conveying part 10 is filled with the required number of blocks.

[0087] 8) The clamping machine 21 stacks the blocks at the stacking position 61 → the clamping machine 21 rises → grabs the top 4 layers of blocks from the block stack, rotates them and places them on the transport layer 72 at the stacking position 62 → returns to the stacking position 61 and waits.

[0088] 9) The palletizing device 30 moves from the first temporary storage platform 311 to the stacking position 61, clamps the bottom two layers of building blocks, first clamps a whole layer, rotates it and places it at the stacking position 62 to form the stacking bottom layer 71, then clamps another whole layer and places it at the stacking position 62 to form the transport layer 72, and places the remaining building blocks side by side at the first temporary storage platform 311 → stops at the first temporary storage platform 311 and waits.

[0089] 10) Repeat steps 7 → 8 → 9.

[0090] 11) When step 9 is completed, the first temporary storage platform 311 is filled with two layers of building blocks for the second time.

[0091] 12) The lifting platform of the first conveying part 10 is filled with the required number of blocks.

[0092] 13) The clamping machine 21 stacks the blocks at the stacking position 61 → the clamping machine 21 rises → grabs the top 4 layers of blocks from the block stack, rotates them and places them on the transport layer 72 at the stacking position 62 → returns to the stacking position 61 and waits.

[0093] 14) The palletizing device 30 moves from the first temporary storage platform 311 to the stacking position 61, clamps the bottom two layers, first clamps a whole layer, rotates it to the stacking position 62, and stacks the bottom layer 71. It then clamps another whole layer and stacks it to the stacking position 62 to stack the transport layer 72. It then places the excess blocks side by side on the second temporary storage platform 312, and then stops at the first temporary storage platform 311 to wait.

[0094] 15) Repeat steps 12 → 13 → 14.

[0095] 16) When step 14 is completed, the second temporary storage platform 312 is filled with two layers of building blocks.

[0096] 17) The lifting platform of the first conveying part 10 is filled with the required number of blocks.

[0097] 18) The clamping machine 21 stacks blocks at the stacking position 61 → the clamping machine 21 rises → the top 4 layers of blocks are stacked and rotated to be placed on the transport layer 72 at the stacking position 62 → returns to the stacking position 61 and waits.

[0098] 19) The stacking device 30 is at the first temporary storage platform 311 → first clamps a whole layer and rotates it to the stacking position 62 to stack the bottom stacking layer 71, then clamps another whole layer and places it to the stacking position 62 to stack the transport layer 72, and puts the excess blocks back to the first temporary storage platform 311 and places them side by side.

[0099] 20) The stacking device 30 goes to the second temporary storage platform 312 and clamps two layers of building blocks onto the transport layer 72 at the stacking position 62 in two batches → stops at the first temporary storage platform 311 and waits.

[0100] 21) The clamping machine 21 clamps the bottom two layers of blocks at the stacking position 61 to the stacking position 62, completing the stacking of the blocks → returns to the stacking position 61 and waits.

[0101] Repeat this cycle.

[0102] Example 2

[0103] The packaging method of the second embodiment differs from that of the first embodiment in that the order of transporting the blocks is different and the number of layers of the block stacks formed by stacking is different, and the packaging method of the second embodiment uses the packaging line of the above-mentioned second embodiment. Specifically, the first and second layers of the block stack from top to bottom are transported to the stacking position 62 by the stacking device 30, and stacked in sequence to form a stacking bottom layer 71 and a transport layer 72 of the block stack, and the remaining blocks in the second layer are placed on the temporary storage platform 31. The steps include: the transport device 20 clamps the block stack at the stacking position 61 on the lifting platform and transports it to the first temporary storage platform 311, the stacking device 30 grabs all the blocks of the first layer from the first temporary storage platform 311 and transports them to the stacking position 62, and then the stacking device 30 grabs all the blocks of the second layer from the first temporary storage platform 311 and transports them to the stacking bottom layer 71, and the stacking device 30 grabs the remaining blocks in the second layer except the blocks stacked in the transport layer 72 and transports them to the second temporary storage platform 312. In the first embodiment, the required building blocks are directly transferred from the building block pile at the stacking position 61 to the stacking position 62. Finally, the building block stack formed at the stacking position 62 has the same number of building block layers as the building block pile at the stacking position 61. In the present embodiment, the entire building block pile at the stacking position 61 is first transferred to the first temporary storage platform 311, and then the required building blocks are transferred from the first temporary storage platform 311 to the stacking position 62. A new stack of building blocks can be formed again at the stacking position 61. Therefore, after the stacking bottom layer 71 and the transport layer 72 are stacked, the transfer device 20 can clamp a whole stack of building blocks from the stacking position 61 and transfer it to the transport layer 72 to form a building block stack. Therefore, the building block stack formed in this embodiment has two more layers of blocks than the building block stack at the stacking position 61, that is, the number of layers of the building block stack formed in this embodiment is two more than the number of layers of the building block stack formed in the first embodiment, thereby increasing the number of building blocks contained in each building block stack and improving the transfer efficiency.

[0104] Specifically, taking a building block with a size of 200×200×600 mm as an example, the building block stack obtained by the packaging method of this embodiment includes 8 layers of building blocks, and the corresponding building block stack size is 1200×1200×1600 mm.

[0105] In this embodiment, after the transfer device 20 clamps the block pile on the lifting platform and transfers it to the first temporary storage platform 311, a second block pile is formed on the lifting platform. In the step of transferring the multi-layer blocks at the lifting platform to the stacking position 62 through the transfer device 20, the clamping machine 21 is used to transfer the second block pile on the lifting platform to the stacking position 62. The second block pile is stacked as a whole on the stacked transport layer 72 to form a block stack. The number of layers of the block stack is two more than the number of layers of the block stack, the number of blocks contained is more, and the transfer efficiency is higher.

[0106] In this embodiment, after the remaining building blocks in the second layer are transferred to the second temporary storage platform 312, the packaging method further includes: when the second temporary storage platform 312 is filled with at least one layer of building blocks, the stacking device 30 grabs the building blocks from the second temporary storage platform 312 and transfers them to the stacking position 62 to form a stacking bottom layer 71 or a transport layer 72. Specifically, when the building blocks on the second temporary storage platform 312 are stacked with the number of one layer of building blocks and the stacking bottom layer 71 needs to be stacked on the stacking position 62, the stacking device 30 grabs a layer of building blocks from the second temporary storage platform 312 and transfers it to the stacking position 62 to form the stacking bottom layer 71. When the stacking position 62 needs to stack a transport layer 72, the stacking device 30 grabs building blocks from the second temporary storage platform 312 and transfers them to the stacking bottom layer 71 to form the transport layer 72. Alternatively, when the building blocks on the second temporary storage platform 312 are stacked with the number of two layers of building blocks and the stacking bottom layer 71 needs to be stacked on the stacking position 62, the stacking device 30 first grabs a layer of building blocks from the second temporary storage platform 312 and transfers it to the stacking position 62 to form the stacking bottom layer 71. Then, the stacking device 30 grabs a layer of building blocks from the second temporary storage platform 312 and transfers it to the stacking bottom layer 71 to form the transport layer 72.

[0107] Taking the building blocks with a size of 200×200×600 mm as an example, the building block stack at the stacking position 61 has 6 layers of building blocks, and the stacked building blocks have 8 layers of building blocks. The size of the building block stack is 1200×1200×1600 mm. The specific steps of the packaging method are as follows:

[0108] The blocks are grouped and stacked on the lifting platform of the first conveyor 10. The block clamping machine 21 stacks the blocks at the stacking position 61 and then grabs a whole stack of blocks at the stacking position 61 and stacks them on the first temporary storage platform 311. The stacking device 30 grabs the blocks from the first temporary storage platform 311 and stacks them at the stacking position 62 to form a stack of blocks on the bottom layer 71 and the transport layer 72. The remaining blocks are placed on the second temporary storage platform 312. The block clamping machine 21 rotates and clamps the six layers of blocks at the stacking position 61 to the stacking position 62 to form a stack of blocks. The stack of blocks is transported by the second conveyor 40 to the packing machine for packing. The stack of blocks is then forked away by a forklift for transportation. When the blocks on the second temporary storage platform 312 are full of one or two layers, the stacking device 30 grabs blocks from the second temporary storage platform 312 and stacks them on the stacking bottom layer 71 or the transport layer 72.

[0109] Example 3

[0110] The packaging method of Example 3 differs from that of Example 1 in whether the blocks are rotated, and the packaging method of Example 3 uses the packaging line of the above-mentioned Example 3. Specifically, the first conveying part 10 and the second conveying part 40 are arranged vertically, and the first preset direction is perpendicular to the second preset direction. Therefore, when using the clamping machine 21 to transfer the blocks, there is no need to rotate the blocks, and the length direction of the blocks is already parallel to the second preset direction.

[0111] Taking a block with a size of 200×200×600 mm as an example, the block pile at stacking position 61 has 6 layers of blocks. The stacked block pile includes 6 layers of blocks, and the size of the block pile is 1200×1200×1200 mm. The specific steps of the packaging method are as follows:

[0112] The blocks are grouped and stacked on the lifting platform of the first conveying section 10, and the block clamping machine 21 stacks the blocks at the stacking position 61 and then stops at the waiting position 63. The stacking device 30 clamps the blocks from the stacking position 61 to the stacking position 62 and stacks them on the stacking bottom layer 71 and the transport layer 72. The excess blocks are placed on the first temporary storage platform 311 or the second temporary storage platform 312. The block clamping machine 21 clamps the remaining four layers of blocks at the stacking position 61 directly to the stacking position 62 to form a block stack. The block stack is transported by the second conveying section 40 to the packing machine for packing. The forklift picks up the block stack for transportation. When the blocks on the first temporary storage platform 311 or the second temporary storage platform 312 are stacked on one or two layers, the stacking device 30 grabs the blocks from the first temporary storage platform 311 or the second temporary storage platform 312 and stacks them on the stacking bottom layer 71 or the transport layer 72.

[0113] It can be understood that, as an alternative embodiment, when the stacking device 30 places the building blocks on the first temporary storage platform 311, it can also stack the building blocks according to the preset arrangement rules of the building block stack to form a building block stack, and then the clamping machine 21 clamps the entire stack of building blocks to the stacking position 62 and transports it away by the second conveying part 40.

[0114] Example 4

[0115] The packaging method of the fourth embodiment differs from that of the third embodiment in that the order of transporting the blocks is different and the number of layers of the block stacks formed by stacking is different. In addition, the packaging method of the fourth embodiment uses the packaging line of the fourth embodiment. Specifically, the third embodiment directly transports the required blocks from the block pile at the stacking position 61 to the stacking position 62, and the number of block layers of the block stack finally formed at the stacking position 62 is equal to that of the block pile at the stacking position 61. In this embodiment, the entire stack of blocks at the stacking position 61 is first transported to the transport conveyor line 90, and the transport conveyor line 90 transports the entire stack of blocks in a direction opposite to the second preset direction. The stacking device 30 is transported from the transport conveyor line 90 to the stacking position 61. The building blocks are grabbed from the tail end and stacked at the first stacking position 621 to form the stacking bottom layer 71 and the transport layer 72, and the excess building blocks are placed on the temporary storage platform 31. The stacked stacking bottom layer 71 and the transport layer 72 are transported from the first stacking position 621 to the second stacking position 622 along the second preset direction. Then, the transfer device 20 can transfer the newly formed whole stack of building blocks at the stacking position 61 as a whole to the transport layer 72 at the second stacking position 622, thereby forming a building block stack. Therefore, the number of layers of the building block stack formed in this embodiment is two more than the number of layers of the building block stack formed in Example 3, which increases the number of building blocks contained in each building block stack and improves the transfer efficiency.

[0116] At the same time, compared with the packaging method of the second embodiment, when the transfer device 20 of this embodiment transfers a newly formed whole stack of building blocks at the stacking position 61 to the second stacking position 622, the transfer device 20 does not need to cross the temporary storage platform 31, while the packaging method of the second embodiment requires the transfer device 20 to cross the first temporary storage platform 311. In the packaging method of the second embodiment, since the first temporary storage platform 311 still contains multiple layers of building blocks other than the first and second layers when the transfer device 20 is required to transfer the newly formed whole stack of building blocks at the stacking position 61, the transfer device 20 needs to be raised during movement to avoid collision with the building blocks on the first temporary storage platform 311. However, in this embodiment, since the transfer device 20 does not need to cross the temporary storage platform 31, it only needs to raise the height of the stacking bottom layer 71 and the transport layer 72 when reaching the stacking position 62. This reduces the lifting distance, reduces the workmanship of the drive device, saves energy, and improves safety.

[0117] Taking the building blocks with a size of 200×200×600 mm as an example, the building block stack at the stacking position 61 has 6 layers of building blocks, and the stacked building blocks have 8 layers of building blocks. The size of the building block stack is 1200×1200×1600 mm. The specific steps of the packaging method are as follows:

[0118] The blocks are grouped and stacked on the lifting platform of the first conveying section 10, and the clamping machine 21 stacks the blocks at the stacking position 61 and then clamps a whole stack of blocks at the stacking position 61 and stacks them on the transfer conveyor line →→ the transfer conveyor line transports the block stack from its head to its tail → the stacking device 30 clamps the blocks from the tail of the transfer conveyor line to the first stacking position 621 and stacks them on the stacking bottom layer 71 and the transport layer 72, and places the excess blocks on the temporary storage platform 31 → the second conveying section 40 transports the stacking bottom layer 71 and the transport layer 72 at the first stacking position 621 to the second stacking position 622 → the clamping machine 21 clamps a whole stack of blocks at the stacking position 61 directly to the transport layer 72 at the second stacking position 622 to form a block stack → the block stack is transported to the baler by the second conveying section 40 for packaging → the forklift forks the block stack for transportation. When the building blocks on the temporary storage platform 31 are full of one or two layers, the stacking device 30 grabs the building blocks from the temporary storage platform 31 and stacks them on the stacking bottom layer 71 or the transport layer 72 .

[0119] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0120] 1. The packaging line can choose one of the various layouts according to the factory environment conditions, and is highly applicable to different factory spaces.

[0121] 2. According to the needs, the packaging line can be arranged in different ways to stack more layers of blocks and speed up the packaging process of the blocks.

[0122] 3. The blocks are stacked and transferred at the same work station. The equipment has a compact layout, saves installation space, and is highly applicable to different factory spaces.

[0123] 4. During the packaging process, the stacking bottom layer 71 and the transporting layer 72 are stacked layer by layer by the stacking device 30, and the remaining layers in the block pile are stacked at one time by the transfer device 20, which speeds up the production cycle.

[0124] 5. The universal design of the conveyor line can be arranged with two-way arrow packaging, or longitudinal packaging machine + laminating machine (or horizontal packaging machine).

[0125] 6. The gripper of the manipulator can be adjusted, suitable for gripping blocks of various sizes.

Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
