The three parts all adopt variable frequency control motors, so that the running speed of the whole machine can be conveniently adjusted; the two sides of the conveying belt are provided with the guide strips, so that the deviation of the belt body in the moving process is prevented, and the addition of complicated deviation prevention devices is reduced; the width of the conveyor belt is set by the front side blank cutting machine.

The compact gantry lifting, lifting and transporting stacking manipulator comprises a clamping mechanism, a swing mechanism, a guide mechanism, a horizontal walking mechanism, a lifting mechanism, a safety protection mechanism and the like. The clamping mechanism adopts pneumatic clamping, and the contraction and the extension of the air cylinder respectively complete the blank clamping and blank releasing functions; the clamping plates are designed by adopting a brick-clamping plate and are respectively fixed on linear bearings serving as sliding and supporting carriers, and each row of green bricks are fixed on a supporting main beam as a unit, so that a small and independent clamping unit is formed; the clamping units are hoisted on the slide ways by using the rollers, and nylon belts are used as limiting devices of the units; each unit is symmetrically arranged by adopting double cylinders and is fixed on the middle immovable clamping plate by a connecting rod; for green bricks with different specifications, different clamping requirements can be realized by adjusting the length of the nylon belts, the fixing positions of the clamping plates and the number of the supporting main beams; the transverse guiding of each clamping unit is controlled and realized through pneumatics, and the control of the transverse distance is also controlled through a limit nylon belt; the blank placing link is also provided with a blank pressing frame for preventing green bricks from being adhered and toppled, and the lifting of the blank pressing frame is controlled by cylinders at four corners.

The slewing mechanism is divided into an upper slewing bearing table, a middle connection and a lower slewing bearing table, the upper slewing bearing table is connected with the upper end of the middle connection through a bolt, the lower end of the upper slewing bearing table is connected on a large-scale ball type slewing support serving as a slewing main body through a bolt, and then the ball type slewing support is connected with the lower slewing bearing table through a bolt; the lower rotary bearing table is provided with a large transmission gear ring which is meshed with a gear on a speed reducer to form a rotary power transmission chain, and the rotary power transmission chain is matched with a speed regulating motor and a limit photoelectric switch to realize the rotation of crossed falling layer stacking blanks; the design of the mechanism adopts a nested landing design, and the rotary support and the intermediate connection are arranged in the upper rotary bearing table, so that the height of the whole machine is greatly reduced.

Detailed Description

As shown in the figure, after the green bricks are cut by the front side green brick cutting machine, the green bricks are transferred to the green brick detection platform 6 by the green brick receiving platform 2 for temporary storage and alignment treatment, initially, the green brick blocking cylinder 7 is in an extending state, the green brick blocking beam 34 is in a working position, the function of the green brick blocking beam is just to cut the finished green bricks on the front side of the green bricks, and the working procedure is essential to single and double mud strips; when the green brick cutting table is used for cutting, if green bricks are broken, a manual operation button can be pressed to extend a green brick detection cylinder 9, a conveying belt on the upper side of the whole green brick detection table is lifted, the broken green bricks conveyed from the front side can directly fall off from the lower end of the green brick detection table 6 to be separated from a conveying chain, then the broken green bricks are conveyed away by the conveying belt on the lower side of the green brick detection table 6 and are stirred again, and the operation flow is continued when the green bricks are good;

after the green bricks are aligned in place, the green brick blocking cylinder 7 contracts, the green brick blocking beam 34 raises to a vacant position and then sends a signal, for a single mud strip, the green bricks are directly conveyed to the green brick distributing table 12 from the green brick detecting table 6, and then the distance between the green bricks is adjusted by the stepping control of the green brick distributing table 12; for double mud strips, the step control of the blank detecting table 6 and the blank distributing table 12 is carried out, so that the two green bricks are sequentially conveyed to the blank distributing table 12, and the step action of the blank distributing table 12 is relied on to complete the requirement of the distance between the mud strips; when 12 green bricks are piled up on the green brick distributing table, the next transfer stroke starts;

receiving the in-place signal of the front side green brick, descending the whole lifting part to the designated position under the control of the lifting control motor 21 and sending a green brick clamping signal, contracting the green brick clamping by the clamping plate 13 under the control of the clamping cylinder 14, ascending the whole lifting part in place to the preset high position under the control of the lifting control motor 21 and sending a walking signal; the walking driving motor 33 drives the walking main frame 28 and drives the lifting part to transversely move to a specified blank falling position; if the number of the blank falling layers is an odd number, the rotation control motor 20 does not perform rotation driving action; if the number of the layers is even, the rotary control motor 20 performs rotary driving to drive the whole chuck to rotate by 90 degrees, so that the crossed blank falling between the layers is realized; when the whole lifting part travels to a specified green brick falling position and receives a signal in place, the lifting control motor 21 drives the whole lifting part to fall to the specified position, the green compact frame control cylinder 17 extends out, the green compact frame 16 falls to the upper surface of a green brick to press the green brick, at the moment, the clamping cylinder 14 clamps and ventilates in the positive direction and is disconnected, and the clamping force of the clamping plate 13 on the green brick disappears; then the lifting control motor 21 drives, the whole lifting part lifts and breaks away from the green brick, and sends a signal after running to a designated high position, at the moment, the walking drive motor drives, and the walking main frame 28 drives the lifting part to return to the pre-green brick clamping position; after the blank is in place, the lifting control motor 21 is started, and the whole lifting part is lowered to the blank clamping prefabricating position to start the next cycle action;

for the tunnel kiln with the small section, when the number of the blanks to be clamped is small at one time, the blank clamping can be realized by adjusting the number of the blanks to be clamped of the front-side ground conveying chain, the corresponding clamping part only needs to be simply adjusted, the modification of the whole machine is not needed, and the tunnel kiln with the small section has multiple purposes.
