Description

The invention relates to the field of building materials industry and can be used in devices involving the removal and tilting of products. Known machine for setting up bricks on kiln cars with simultaneous tilting from position to plate J3 position to edge tl. The specified machine has a separate conveyor-tilter and pusher. Transferring bricks to the component device. It is also known a device for moving piece blanks, containing a hinged arm mounted on a device base mounted on a device base in a vertical plane, a supporting arm parallelogram and pivotally connected to it with a possibility of relative swinging motion in a vertical plane, a lever parallelogram with a gripping body mounted on it, receiving movement from the drive through a crank mechanism, the crank of which is mounted on the output shaft of the drive These structures are the complexity of the transfer mechanism, which leads to an extra expenditure of power, fuzzy work and deformation of the rows of bricks formed. The purpose of the invention is to improve the design. And ensure the rotation of products by 90 °. This is achieved by the fact that in a puller-tilter containing a crank-beam mechanism and pivotally connected to it, coaxially arranged. Hinged parallelograms with gripping bodies mounted on their output links are grip bars, cheeks, thrust rollers and The cheeks are hinged on the kerchiefs and carry the thrust rollers interacting during the working stroke with the guides mounted above the press table. Fig, 1 shows the proposed device; Fig, 2 is a top view. The device contains a crank mechanism, consisting of a rocker arm 1, a connecting rod 2 and a drive crank 3, mounted on a shaft 4 mounted in fixedly mounted bearing housings 5 and hinged parallelograms connected to it, including levers 6 and 7, consoles 8 and tongues 9, interconnected by shafts 10 and 11.

Since the arms b and 7 have the same length, the distance between the articulated joints of these levers with kerchiefs 9 is equal to the length of the console 8, the four hinge evens are parallelograms, and the kerchiefs 9, which are from the press table to the conveyor and back, do not change its orientation in space. The right and left cheeks 12, 13, 14, 15 are pivotally suspended to the kerchiefs 9, which in a free state occupy a vertical position, the result of which is their center of gravity, under the hinges attached to the kerchief.

The cheeks 12-15 are provided with clamping air cushions 16 and stop rollers 17 for orienting the cheeks above the press table under the action of guide pads 18 mounted under the press table when gripping the bricks 19. The receiving conveyor 20 is located above the shaft 4.

The tilter works as follows.

When the pressed bricks 19 are on the press table, under the action of the crank mechanism 1, 2j 3, the shaft 4 rotates together with the levers b towards the table the kerchief 9 together with the cheeks 12-15 are lowered onto the table. In this case, the thrust rollers 17 of the cheeks meet the guide pads 18, as a result of which, as they approach the table of the press, the cheeks are forced to assume a horizontal position, corresponding to the position of the bricks of the flat on the press,

 In the lowermost position, above the press table, the cheeks 12–15 cover on both sides each pressed brick. At this point, compressed air is supplied to the pneumatic pads 16. and they pinch the bricks, When, following this, the crank mechanism

causes the transfer of the kerchiefs from the table to the conveyor; the clamped bricks also move away from the press table;

As you lift, the thrust rollers 17 of the cheeks 12-15 are first transferred over the guide pads 18, and then detached from them. However, the cheeks, along with the bricks, are rotated from a horizontal position to a position of free vertical overhang and in this condition, approach the receiving conveyor 20. In this final position, the bricks become tightly together on the conveyor, and immediately the air comes from the pneumatic pillows 16 is produced.

The bricks cleared of crushing are removed by the conveyor, and the tilter can repeat the cycle of the described operations to remove the next group of bricks from the press.
