After a stack of green bodies reaches the rotating station, the rotating crane lifts the upper half of the stack of blocks, rotates them by 90 degrees and then lowers them to complete the rotation. Then the entire stack of green bodies is lifted for hoisting. Only one stack of green bodies can be rotated at a time, which results in low rotation efficiency and slow block production.

[0041] DETAILED DESCRIPTION

[0042] The technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0045] Furthermore, 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.

[0046] Example 1

[0047] like Figures 1 to 3 As shown, the block rotating device of this embodiment includes: a plurality of rotating platforms 10 and a plurality of transverse driving units 20. The plurality of rotating platforms 10 are arranged along a preset direction, each rotating platform 10 has a bearing surface for bearing blocks, and each rotating platform 10 is adapted to drive multiple layers of blocks to rotate horizontally; each transverse driving unit 20 is disposed between two adjacent rotating platforms 10, and each transverse driving unit 20 has an open state that moves adjacent rotating platforms 10 away from each other and a retracted state that moves adjacent rotating platforms 10 closer to each other.

[0048] Using the block rotation device of this embodiment, multiple stacks of blocks to be rotated are placed on the bearing surfaces of multiple rotating platforms 10 using an existing crane. The crane lifts the upper half of the stacks of blocks, and then the multiple rotating platforms 10 increase their spacing and rotate the lower half of the stacks of blocks. After rotation, they return to their original positions. At this time, the crane lowers the upper half and lifts the entire stack of blocks for unloading. Multiple rotating platforms 10 can rotate multiple stacks of blocks simultaneously, which greatly speeds up the block posture adjustment process. At the same time, in conjunction with the crane, multiple stacks of blocks can be unloaded in one go, significantly improving the unloading cycle of blocks and effectively solving the problem of slow unloading cycle caused by low rotation efficiency of stacked blocks in the prior art.

[0049] It should be noted that, since the existing crane simultaneously hoists multiple stacks of blocks, the multiple stacks of blocks are not spaced apart and the overall stack of blocks is a rectangular block. In order to facilitate the simultaneous rotation of the multiple stacks of blocks, after the multiple stacks of blocks are placed on the block rotating device, a certain distance needs to be pulled between each rotating table 10 to ensure that each stack of blocks does not interfere with adjacent blocks during rotation. Therefore, the multiple transverse driving portions 20 are provided only to cooperate with the existing crane. If the crane can simultaneously transport multiple stacks of spaced apart blocks, the transverse driving portion 20 does not need to be provided.

[0050] Specifically, the number of rotating tables 10 is not limited, and can be matched according to the maximum number of block transport stacks of the crane used, so as to as far as possible speed up the off-line rhythm and improve the work efficiency.

[0051] In the present embodiment, each rotating table 10 includes a support plate 11 and a rotating driving portion 12. The upper end surface of the support plate 11 forms a bearing surface, and the rotating driving portion 12 drives the support plate 11 to rotate horizontally. The stack of blocks can be rotated simply by being placed on the bearing surface, and the adjustment efficiency is effectively improved by the simple structure.

[0052] Specifically, the specific structure and specifications of the rotating driving portion 12 are not limited. The rotating driving portion 12 can be a rotating motor or a rotating cylinder. The specifications of the rotating driving portion 12 are matched according to the specifications of the blocks placed on the bearing surface, and the stack of blocks can be stably and reliably rotated.

[0053] Preferably, the support plate 11 is a rectangular plate, which can better match the bottom surface of the stack of blocks. It can be understood that, as an alternative embodiment, the support plate 11 can also be a circular plate or other shaped support plate.

[0054] In the embodiment, the block rotating device further comprises a support 30, each rotating table 10 further comprises a support plate 13, the rotating driving part 12 is fixed on the support plate 13, each lateral driving part 20 is connected between two adjacent support plates 13, one support plate 13 is fixed on the support 30, and the rest of the support plates 13 are in sliding fit with the support 30, or each support plate 13 is in sliding fit with the support 30, the support plate 13 bears the rotating driving part 12 and the supporting plate 11 and slides on the support 30, and the structure is simple and convenient for manufacturing. It can be understood that, as an alternative embodiment, one end of each lateral driving part 20 can be fixed on the ground or the support 30, and the other end is fixed on the corresponding support plate 13, each lateral driving part 20 can also be connected between two adjacent rotating driving parts 12, and each support plate 13 can also be in sliding fit with the support 30. It should be noted that the support plate 13 with a certain height is arranged so that the bearing surface of the rotating table 10 can be matched with the conveying surface of the nearby conveying line equipment, and the movement of the crane in the vertical direction during the transfer of the stacked blocks is reduced, which not only saves energy but also reduces the transfer process. If the structure is simplified, the support 30 can also not be arranged, and each rotating table 10 is directly matched with the ground through the support plate 13.

[0055] Specifically, there are five rotating tables 10 and four rotating driving parts 12, the five rotating tables 10 are arranged in a straight line, the bottom surface of the support plate 13 of each rotating table 10 is provided with a sliding groove and is in sliding fit with the sliding rail arranged on the support 30, the rotating table 10 located in the middle is fixed, and the rest can slide, the fixed rotating table 10 plays a positioning role, so that each folding and separating process is more accurate, and the specific structure of the lateral driving part 20 is not limited, which can be an oil cylinder, an air cylinder or a point push rod, and the rotating table 10 can be reliably and continuously driven to move.

[0056] The use mode of the block rotating device of the embodiment will be described below.

[0057] In normal operation, the five rotating tables 10 are initially in a folded state; the crane places the five stacks of blocks that need to be rotated on the five rotating tables 10; the rotating table 10 in the middle is stationary, and the lateral driving part 20 drives the rest of the rotating tables 10 to move, at this time, the five rotating tables 10 are in a separated state; the rotating driving part 12 of each rotating table 10 drives the supporting plate 11 to rotate horizontally by 90 degrees; the lateral driving part 20 drives the rotating tables 10 to fold, and the rotation is completed.

[0058] It should be noted that the "the crane places the five stacks of blocks that need to be rotated on the five rotating tables 10" includes that the crane only places the part of the block layer that needs to be rotated on the rotating table 10, and also includes that the crane places the five stacks of blocks on the five rotating tables 10 and then lifts the upper half of the block layer.

[0059] As Figures 4 to 16As shown, the present application provides a block offline pipeline, which comprises: a block conveying line 43, a packing conveying line 44, a block hoist 41 and the block rotating device described above, the packing conveying line 44 is arranged on one side of the block conveying line 43; the block rotating device described above is arranged between the block conveying line 43 and the packing conveying line 44, and the block rotating device is adapted to rotate the multi-layer block layer; the block hoist 41 is adapted to hoist the block layer on the block conveying line 43 to the block rotating device and hoist the block layer rotated by the block rotating device to the packing conveying line 44.

[0060] In the embodiment, the block conveying line 43 is provided with at least two parallel lines along the connection direction of the packing conveying line and the block rotating device, when one of the block conveying lines 43 cooperates with the block hoist 41, the block conveying line 43 stops conveying blocks and waits for the block hoist 41 to hoist the blocks on the transfer station, at this time, the other block conveying line 43 can still convey normally, reducing the suspension time and improving the block conveying efficiency. It can be understood that as an alternative embodiment, only one block conveying line 43 can also be arranged to realize the transfer requirement but with lower conveying efficiency.

[0061] Specifically, the five stacks of blocks are composed of two parallel block columns, each block column can be composed of multiple blocks or one block, and the block conveying line 43 can convey two parallel block columns, when the two block columns are conveyed to the transfer station of the block hoist 41, the block hoist 41 merges the two block columns into a stack of blocks and hoists it up.

[0062] In the embodiment, the packing conveying line 44 is provided with a tray dispenser 441 and a tray limiting part 442, the tray dispenser 441 is adapted to place a plurality of trays on the packing conveying line 44, and the tray limiting part 442 is adapted to limit the movement of the tray 443 on the packing conveying line 44, the tray limiting part 442 can change a plurality of closely arranged trays 443 into a single independent tray 443, and separate the multiple stacks of blocks, so that the subsequent packing offline process is more convenient.

[0063] Specifically, the tray limiting part 442 comprises a limiting driving part and a stop block, the driving part drives the stop block to extend or retract, when the stop block extends, the side wall thereof abuts against the side wall of the tray 443 and prevents the tray 443 from continuing to move. The limiting driving part can be a driving cylinder or a driving structure capable of driving the stop block to periodically reciprocate, such as a rotating cam, a rotating eccentric wheel, etc., and the stop block can be a metal block or a plastic block, preferably made of rubber or nylon, which can buffer the impact when the tray 443 is blocked.

[0064] The specific limiting process of the tray limiting part 442 is as follows: Figures 5 to 7As shown, the five pallets are blocked in the preset position by the stopper, and the five stacks of blocks are carried by the five corresponding pallets when being transferred to the packing conveying line 44, at this time, the five stacks of blocks are in close contact with each other, at this time, the stopper is retracted, and the five pallets move along the packing conveying line 44, when it is determined that the first stack of blocks flows out, the stopper is extended to organize the remaining blocks to move, and after the first stack of blocks moves a certain distance, the stopper is retracted, and the remaining blocks move along the packing conveying line 44, at this time, the state of the second stack of blocks is determined again and the above steps are repeated, so that the five stacks of blocks have a certain interval.

[0065] In the embodiment, a plurality of packing machines 48 and a plurality of forklifts are further arranged on one side of the packing conveying line 44, and each stack of blocks separated on the packing conveying line 44 is taken away by the forklift after passing through the packing machine 48.

[0066] In the embodiment, a bottom plate conveying line 45, a finished product hoist 46, a separating machine 47 and a single-mode hoist 42 are further included, the bottom plate conveying line 45 is arranged on the side of the parallel block conveying line 43 away from the packing conveying line 44, the finished product hoist 46 is suitable for hoisting the single-mode block 51 to the bottom plate conveying line 45, the separating machine 47 is arranged between the finished product hoist 46 and the single-mode hoist 42, and the separating machine 47 is suitable for separating the single-mode block 51, and the single-mode hoist 42 is suitable for hoisting the single-mode block 51 on the bottom plate conveying line 45 to the parallel block conveying line 43, and the existing structure and device can meet the offline process.

[0067] The application further provides a block offline method, wherein the multiple layers of blocks on the parallel block conveying line 43 are hoisted to the bearing surfaces of the multiple rotating tables 10 of the block rotating device by the parallel block hoist 41; the posture of the multiple layers of blocks is adjusted and multiple stacks of blocks are formed by cooperation of the block rotating device and the parallel block hoist 41; the multiple stacks of blocks on the multiple rotating tables 10 are hoisted and transferred to the packing conveying line 44 by the parallel block hoist 41; wherein the step of adjusting the posture of the multiple layers of blocks by the block rotating device comprises: the multiple rotating tables 10 are driven apart by the multiple transverse driving parts 20 of the block rotating device; the blocks on the multiple rotating tables 10 are rotated by 90 degrees; the multiple rotating tables 10 are driven to close by the multiple transverse driving parts 20, and the multiple stacks of blocks can be rotated at the same time by the multiple rotating tables 10, which greatly speeds up the rotation rhythm compared with the rotation and offline of each stack of blocks.

[0068] In the step of hoisting the multi-layer block layer on the parallel block conveying line 43 to the bearing surface of the plurality of rotating tables 10 of the block rotating device by the parallel block hoist 41 in the embodiment, the two-module block 52 on the parallel block conveying line 43 is placed on the plurality of rotating tables 10 by the parallel block hoist 41; the step of adjusting the posture of the multi-layer block layer and forming the multi-stack block stack by the block rotating device and the parallel block hoist 41 comprises: hoisting the upper block layer of the two-module block 52 by the parallel block hoist 41; adjusting the posture of the lower block layer of the two-module block 52 by the block rotating device; and placing the upper block layer on the lower block layer by the parallel block hoist 41. The parallel block hoist 41 only needs to move horizontally once to rotate the multi-stack block, which is more efficient and faster in rotation rhythm.

[0069] In the step of transferring the multi-stack block stack to the packing conveying line 44 by the parallel block hoist 41 in the embodiment, the multi-stack block stack is placed on the tray on the packing conveying line 44 by the parallel block hoist 41; after the step of hoisting the multi-stack block stack on the plurality of rotating tables 10 by the parallel block hoist 41 and transferring to the packing conveying line 44, the block offline method further comprises: limiting the movement of the tray by the tray limiting part 442 on the packing conveying line 44 to sequentially separate the multi-stack block stacks, so that each block stack is more convenient for packing and the offline step is easier to adapt to the existing production line.

[0070] In the step of hoisting the multi-layer block layer on the parallel block conveying line 43 to the bearing surface of the plurality of rotating tables 10 of the block rotating device by the parallel block hoist 41 in the embodiment, the multi-layer block layer on the parallel block conveying line 43 is hoisted to the bearing surface of the plurality of rotating tables 10 of the block rotating device by the parallel block hoist 41; after the step of hoisting the multi-stack block stack on the plurality of rotating tables 10 by the parallel block hoist 41 and transferring to the packing conveying line 44, the block offline method further comprises: limiting the movement of the tray by the tray limiting part 442 on the packing conveying line 44 to sequentially separate the multi-stack block stacks, so that each block stack is more convenient for packing and the offline step is easier to adapt to the existing production line.

[0071] In the embodiment, when there are two or more parallel block conveying lines 43, after the two-module block 52 is placed on any one of the parallel block conveying lines 43, the single-module hoist 42 hoists the single-module block 51 on the bottom plate conveying line 45 to the remaining parallel block conveying lines 43, so that the single-module hoist 42 can continue to transfer the single-module block 51 to the remaining parallel block conveying lines 43 without waiting for the previous parallel block conveying line 43, thereby speeding up the transfer rhythm.

[0072] It should be noted that the block offline method of the embodiment can use the block rotating device or the block offline assembly line described above.

[0073] Embodiment Two

[0074] As Figures 15 to 16 shown, the block offline method of embodiment two is different from that of embodiment one in whether to additionally place a multi-layer block layer. In embodiment two, the step of adjusting the posture of the multi-layer block layer and forming a multi-stack block stack through the cooperation of the block rotating device and the block stacking crane 41 further comprises: adjusting the posture of the two-mold block 52 through the block rotating device; and placing the multi-layer block layer on the block stacking line 43 onto the two-mold block 52 after the posture adjustment through the block stacking crane 41. This makes the offline process not only meet the original block stack offline with the original stacking height, but also be applicable to the block stack with a higher stacking height. An additional stacking step is added to the original process, which is simple, fast and easy to implement.

[0075] It should be noted that the block offline method of the embodiment can use the block rotating device or the block offline assembly line described above.

[0076] From the above description, it can be seen that the above-mentioned embodiments of the present application achieve the following technical effects:

[0077] 1. The multi-stack block is placed on the bearing surface of the plurality of rotating tables 10 by the existing crane. The upper half of the multi-stack block is lifted by the crane, and then the plurality of rotating tables 10 increase the interval distance and rotate the lower half of the multi-stack block. After the rotation is completed, the original position is restored. At this time, the upper half is lowered by the crane, and the multi-stack block is lifted as a whole for offline. The plurality of rotating tables 10 can simultaneously rotate the multi-stack block, greatly speeding up the adjustment process of the block posture. At the same time, the crane can offline the multi-stack block at one time, significantly improving the offline rhythm of the block.

[0078] 2. The block stacking line 43 is provided with at least two parallel lines. When one of the block stacking lines 43 cooperates with the block stacking crane 41, the block stacking line 43 stops conveying the block and waits for the block stacking crane 41 to lift the block on the transfer station. At this time, the other block stacking line 43 can still convey normally, reducing the suspension time and improving the block stacking efficiency.

[0079] 3. The posture of the two-mold block 52 is adjusted through the block rotating device, and the multi-layer block layer on the block stacking line 43 is placed onto the two-mold block 52 after the posture adjustment through the block stacking crane 41. This makes the offline process not only meet the original block stack offline with the original stacking height, but also be applicable to the block stack with a higher stacking height. An additional stacking step is added to the original process, which is simple, fast and easy to implement.
