Description

one

The invention relates to the DFG lines for the manufacture of bricks and other products by extrusion and can be used in the industry of construction materials.

The aim of the invention is to increase reliability in operation.

FIG. 1 shows the automatic line, plan; in fig. 2 - vi A in FIG. 1; in fig. 3 shows a section B-B in FIG. 2; in fig. 4 is a view of B in FIG. 2,

The installation consists of a single-string cutter 1 installed in the technological sequence, separating a brick stock from the clay bar coming out of the press 2, an accelerating conveyor 3, feeding the blank to the multi-string automaton 4, including the string frame 5, the pusher 6 of the beam with a variable stroke and waste conveyor 7.

The automatic machine 8 extending and stacking the products. To the drying trolley 9 of the brick 10 is made in the form of a two-meter lifting stand 11, equipped with a river-bed fixed receiving table 12 and a sliding table 1 3.

The extendable table 13 consists of an elastic sheet propelled from a chain conveyor 14 supported on rollers 15 mounted on the frame 16 of the cage. The automatic machine 8 extends and places the products also includes a push rod 17 of the Kirill with intermittent movement of the working org ..

The lift 18 of the trolley 9 is made with a lifting carriage 19 equipped with cantilever pickups 20. The line also includes a transfer carriage 21 with a displacement drive 22 and pushers 23 and 24 for pushing onto the transfer carriage 21 of the pistons and removing the loaded car 9 from it. established shelves 25, oriented in the direction of movement of the trolley. In the pusher 6 of the beam, slots are made to pass through the strings.

The line is provided in automatic mode, regulated by a given program, using the sensor system

144312

automatic control (not shown).

From the clay bar extruded by the press 2, with a single-stringed sensor 1, a brick blank is cut off, which is accelerated by the container 3 to the multi-stringer cutter 4.

Pusher 6 beams push

10, the brick workpiece through the fixedly installed strings of the string frame 5 and moves the already cut bricks to the position 15 of the fixed leg of the receiving table 12 of the upper tier of cage 1, far from the axis of the accelerating conveyor 3, and then returns to its original position. The waste generated during the cutting of timber is fed to the waste conveyor 7

20 and further - into the clay mixer of the press 2. Subsequent groups of bricks pusher 6 moves successively to the middle and near positions of the receiving table 2 of the stand 11.

25 At this point, the trolley 9 with the pickups 20 of the lifting carriage 19 of the elevator 18 is removed from the transfer car 21 and set to the position for loading.

30 After having brought the bricks to the near position of the receiving table of the upper cage of the cage, the pusher 6 of the beam returns to its original position, and the cage 11 rises, substituting

35 loading with bricks lower rus and output loaded upper rus to the position of transferring bricks to the upper rus of the drying trolley 9.

40 From under the receiving table 12 of the upper floor of the cage 1I by a chain conveyor 4, the extendable table is fed into the area of the drying car 9 above the upper shelf 25. Then the pusher 17 bricks moves forward by moving groups of bricks installed on the receiving table to the sliding table 13. Chain drives conveyor 14 and collider 17

5Q bricks are reversed and they begin to move to their original position, and their speeds are equal, but the movement of the sliding table 13 is continuous, and the knocker 17 of cyrJ5 of chippers is discontinuous, which ensures that 25 bricks 10 are placed on the shelf with the gaps required by the drying conditions.

by the time the retractable table 13 and the stack of 17 bricks of the upper russ of cage 11 are returned to their initial position, the cycle of loading bricks of the lower russ of the cage is completed and the cage 11 is lowered, the upper russ is now loaded and the loaded lower is in the position of transferring the products to the trolley. This transfer is sluggish in the same way as described above.

After each cycle of raising and lowering the cage 11, the carriage 19 of the elevator 18 rises in a step corresponding to the step of the shelves 25 on the car.

The pitch of the shelves 25 of the trolley 9 and the distance between the crusts of the cage I are related by the ratio

h 0,25t n,

h is the cube distance between the cages;

t - step shelves trolley;

p - the number of shelves on the wagon.

214431

This ratio allows synchronization of the operation of the trolley lift 18 and the stand 11, ensures the continuity of the technological process of manufacturing products.

At the end of the loading of the trolley, the carriage 19 is lowered to its original position by placing the car 10 on the transfer carriage 21, which transports it to the pusher 24, rolling the car 9 from the transfer car 21. The spacer 23 is vacant

(5 sets the empty trolley, the transfer cart enters it into the area of the elevator 18, the carriage of which moves up, push the trolley 9 with the hooks 20 and set it to its initial position for loading.

The use of the line makes it possible to improve the quality of the products and the reliability of operation, which

account provides increased productivity.
