the working state of the brick unloading machine is cycled back and forth, and the working steps from the second layer to the eleventh layer are the same as the above; the first brick unloading step is completed, and the later steps are circulated back and forth;

c. the chain type braiding platform transports and walks:

the brick unloading machine grabs bricks to the first chain table and descends to the position of the grouping chain, a second photoelectric switch of the first chain table gives a signal, the first chain table and the second chain table are started simultaneously, the first chain table conveys bricks and empties the bricks, and the brick unloading machine continues to discharge the bricks; whether the first chain table is empty is detected and judged through a third photoelectric switch A, when the third photoelectric switch A acquires a signal, and then the signal is lost, the fact that the brick pile arrives at and leaves the third photoelectric switch A is confirmed; therefore, whether the first chain table brick is empty or not is confirmed, when the first chain table is not empty, the brick unloading machine waits not to descend, and the brick unloading machine does not descend until the first chain table is empty; the brick is transported forward to a second chain table continuously, the brick cannot be detected by the first photoelectric switch B, the second photoelectric switch B detects an in-place signal, and the second chain table stops; when the first chain platform is emptied, the bricks can be continuously connected; the second chain table bricks are sewn because gaps exist between the previous brick pile and the next brick pile on the second chain table, and the second chain table waits for a certain time threshold value and finishes sewing;

when in parallel sewing, a second photoelectric switch of the second chain table detects that bricks exist, the cylinder jacks up, the first chain group and the second chain group simultaneously walk and sew to a brick dividing reference line, the cylinder descends, the first chain group and the second chain group reset, and a descending signal of the cylinder is given by the magnetic switch; the bricks are divided into 18 bricks, the 18 bricks in the first group are counted by an encoder, the 18 bricks in the first group are moved to a third chain table and moved to a third photoelectric switch B of the third chain table, a signal is given, a fourth chain table is triggered to move, the rest chain tables are sequentially triggered to start moving, when the bricks are divided to a tail end chain table, the position of the switch signal is detected in place, the tail end chain table is stopped, and brick stacking is waited;

simultaneously, the first chain group and the second chain group are jacked up by the cylinder and move oppositely for parallel sewing, then the cylinder descends, and the encoder counts and divides the chain groups into a second group; the second group comprises two side groups and a middle group; after stacking, intervals are arranged between the marshalling and the middle group, so that forklift hole sites are formed; the two side groups are positioned by a first photoelectric switch C, the middle group is positioned by a second photoelectric switch C, after the first photoelectric switch C and the second photoelectric switch C are positioned at the cross position of a second chain table and a third chain table, the third chain table is conveyed forwards, the second chain table stops moving, and after one side group is positioned, the third chain table drives the side group to continue moving for 200mm to stop; then, positioning the middle group, driving the middle group to continue moving for 150mm by a third chain table, and finally positioning the other side group to move forwards, so that a brick layer with forklift holes is obtained on the third chain table; wherein, the running distance is determined by an encoder on the proximity switch or the third chain table driving mechanism; a third photoelectric switch C detects that a third chain table has bricks and gives a signal, a fourth chain table is triggered to travel, the rest chain tables are sequentially triggered to start to travel, when the bricks are distributed to a tail end chain table, the position of the switch signal is detected in place, the tail end chain table stops, and brick stacking is waited;

jacking and sewing the air cylinder at the second chain table, and dividing the third layer of bricks until one bag is circulated, wherein one bag only has once forked vehicle holes, and the number of the blocks in each layer is the same in the second layer;

brick stacking work: the initial state of the brick unloading machine chuck is the highest point, the stopping position is determined by the stopping limiting stopper, and the brick unloading machine chuck is locked by the magnetic brake of the motor;

after a fifth chain table photoelectric switch of the grouping table detects that bricks exist, the brick stacking machine enters a working state, and the chuck quickly descends to the height of a preset reference line; meanwhile, after a roller table at the bottom of the fifth chain table is jacked up, a chuck of the brick stacking machine is slowly lowered to clamp bricks, after the bricks are clamped, an encoder counts the bricks, the bricks are quickly lifted to the height of a second layer of stacking, and then the bricks are translated to a roller type conveying roller table position with a stacker in-place detection switch, and a motor is magnetically braked; the chuck of the stacker crane descends to the first layer of roller table position to place the bricks; quickly rising to the height of the reference point, and horizontally moving and walking to the chain type conveying reference point; slowly descending to grab the bricks, quickly lifting to the third layer of height of stacking, quickly walking to the brick placing reference position of the roller conveyor, and slowly descending to place the bricks; the loosening claw is quickly lifted and returned, descends slowly to grab the bricks, quickly lifts, walks and rotates to the brick placing position, and descends slowly to place the bricks; sequentially stacking the top layer; when the brick is put to the chuck, the pile up neatly single layer is rotatory 90 when the translation, and the direct translation irrotational of even number layer.

The stop limiter comprises two proximity switches for determining positions and a limit travel switch for performing electromagnetic braking.

When the brick unloading machine and the brick stacking machine work, the speed is regulated through the frequency converter, the machine starts from 16-36% of speed, the machine runs from 70% of speed, and finally 36-16% of speed approaches to a target position.

The datum line and the datum point are preset 0 point positions or starting points, and the datum line and the datum point are heights from the bottom plane of the clamping jaw to the plane of the grouping chain.

After the roller conveyor is stacked by the brick stacking machine for one package, a first roller table 41 and a second roller table 42 of the roller conveyor are started to walk, the roller conveyor walks through a first group of roller tables 41 to a second group of roller tables 42, a photoelectric switch gives a signal, the first roller table stops, and when the first group of roller tables stops, the brick stacking machine continuously works; the second roller table and the third roller table travel, the first photoelectric switch sends out a stop signal at the position of the packaging machine, and the second roller table 42 and the third roller table 43 stop; the packer 44 has a packing signal, starts to pack the first belt, sends out a stop signal to the second photoelectric switch, has a packing signal, packs the second belt, sends out a stop signal to the third photoelectric switch, has a packing signal, packs the third belt, sends out a stop signal to the fourth photoelectric switch, has a packing signal, packs the fourth belt, and completes longitudinal belt packing by the roller conveyor; the third roller table continues to travel to the chain conveyor 45; when the chain conveyor 45 and the roller conveyor connecting platform are in a working state, an oil pump of the roller conveyor always works, and an oil jack is always jacked up; when a pack of bricks moves to the photoelectric switch of the chain-type platform, the photoelectric switch gives a signal, and the connecting platform carrier roller stops and descends; the transfer package is put on a chain of a chain conveyor and is conveyed to a second packer 46 by the chain to be packed, a first photoelectric belt is formed by the transfer package, a second photoelectric belt is formed by the transfer package through a second photoelectric switch, and the packing work is finished.
