Background

At present, the domestic brick sintering process mostly adopts a one-time stacking and sintering process, namely, green bricks are stacked once to complete drying and roasting, and because the surfaces of the green bricks are softened to a certain extent in the process of sintering the green bricks into bricks, the phenomena of bonding between upper and lower layers of bricks, deformation of piled bricks and the like are caused. Therefore, a plurality of complex factors exist in the brick unloading process, the automation of brick unloading is limited, and the brick unloading is still carried out manually at home at present.

The manual work unloads the brick back, directly carries out the loading usually, perhaps carries out the pile up neatly by the manual work and packs into fixed brick pillar, transports the storage in the factory, carries the brick pillar loading at last, makes things convenient for the end user to use, therefore the brick factory packing link is necessary usually.

(5) when the pallet clamping mechanism clamps, the clamp offset frame 70602 first moves by an offset distance L (in this embodiment, L is a distance of half a brick), so that the outermost clamping fingers correspond to the position of the baked brick stopped when the double-stroke cylinder is at the first stroke position, if a or C is an odd number, the clamp offset frame 70602 retracts by the offset distance L, and if a or C is an even number, the clamp offset frame 70602 retracts by the offset distance L and then extends by the offset distance L;

(6) and after the sintered brick layer unit I, the sintered brick layer unit II and the reserved forklift hole sintered brick layer unit are sequentially specified in the vertical direction according to the size and the height of the stacking, stacking the units together in the vertical direction, wherein the clamp offset frame needs to correct the brick clamping center position of the clamping finger unit by adopting a deviation correction method in the stacking process, so that the sintered brick stacking is formed. The stacking process of the sintered bricks provided by the embodiment can realize three-stack stacking, and the specific process method comprises the following steps:

the small pile shaped brick pile (see figure 6) has the I pile shape of 4 multiplied by 18 cross stacking, the forklift hole layer is 3 multiplied by 18, and the brick pile is square pile in the top view. The two small transfer stacking machines clamp and transfer bricks in 2 rows and 18 rows, namely A, B is 4, C, D is 18, and the bricks on the two conveying carrier roller positioning machines 6 are 18 rows.

Middle pile (see fig. 6) II pile form is 4 x 22 and 5 x 18 cross-stacked, forklift orifice layer is 3 x 22, pile overlook shape rectangle pile. When stacking middle stack shapes, one small transfer stacking machine clamps and conveys bricks in 2 rows and 18 columns, and the other small transfer stacking machine clamps and conveys bricks in 2 rows and 22 columns, namely one brick of the two grouped conveying carrier roller positioning machines 6 is in 18 columns, and the other brick is in 22 columns.

Large pile (see fig. 6) III pile form is 5 x 22 cross-stacked, forklift aperture layer is 4 x 22, and pile top view shape is square pile. When stacking and enlarging stacks, the two small transfer stacking machines clamp and transfer bricks in 2 rows and 22 rows, the two conveying carrier roller positioning machines 6 are 22 rows of bricks, namely A, B is 5, C, D is 22, and the two conveying carrier roller positioning machines 6 are 22 rows of bricks.

When the large pallet jack 706 clamps a brick, the clamp offset 70602 is corrected differently for the odd and even rows, as shown in fig. 7.

Divide into to press from both sides when pressing from both sides odd row brick and press from both sides 3 row bricks and 5 row bricks two kinds of circumstances:

when 3 rows of bricks are clamped, the large stacker crane clamp 706 only clamps the bricks in three rows including a second row of clamping fingers 706-2, a third row of clamping fingers 706-3 and a fourth row of clamping fingers 706-4 in the middle; when clamping 5 rows of bricks, all clamping fingers clamp bricks completely.

The work flow when clamping odd rows (3 rows and 5 rows) is as follows: the double-stroke cylinder 603 of the carrier roller positioning machine drives the movable blocking rod 601 to withdraw, finally, the clamping fingers clamp the bricks, the large stacker crane lifts the clamp, meanwhile, the clamp offset frame 70602 withdraws half bricks with the distance of 120mm, the phenomenon that the unclamped bricks incline and stand upside down due to uneven side surfaces of the bricks is avoided, and at the moment, the centers of the bricks in odd rows coincide with the centers of the stacker crane and the corresponding centers of the circulating trays, so that correct stacking is met.

When clamping an even number of rows of bricks, only 4 rows of bricks are clamped:

when 4 rows of bricks are clamped, the first row of clamping fingers 706-1, the second row of clamping fingers 706-2, the third row of clamping fingers 706-3 and the fourth row of clamping fingers 706-4 of the large stacker clamp 706 clamp bricks in four rows.

The working process when clamping even rows (4 rows) is as follows: at last, the double-stroke cylinder 603 of the carrier roller positioning machine drives the movable blocking rod 601 to withdraw, finally, the clamp clamps the bricks, the large stacker crane lifts the clamp, meanwhile, the clamp offset frame 70602 withdraws the half bricks with the distance of 120mm, the phenomenon that the unclamped bricks incline and stand upside down due to the fact that the side faces of the bricks are uneven is avoided, then the clamp offset frame 70602 extends out of the half bricks with the distance of 120mm again, the centers of the bricks in odd rows coincide with the center of the stacker crane and the center of the corresponding circulating tray, and correct stacking is achieved.

The process for reserving the forklift holes comprises the following steps: when the stacker crane clamp 706 clamps 3 rows of bricks to pull open the forklift holes, the lock rod cylinder 70609 in the second row is in a retracted state, and only the middle opening and closing cylinder 70610 extends out to realize 3 rows of bricks to pull open the forklift holes. When the pallet truck clamp 706 clamps 4 rows of bricks and pulls open the forklift holes, the lock rod cylinder 70609 of the second row is in an extending state, the middle opening and closing cylinder 70610 drives the locking rod 70608 of the second row of clamping fingers to extend, the second row of clamping fingers 706-2 are positioned and locked, and the outer opening and closing cylinder 70611 drives the first row of clamping fingers 706-1 to extend to pull open the forklift holes.
