Abstract

The invention relates to the production of building materials, namely, to the production lines of ceramic products. The aim of the invention is to improve the reliability and safety of products. The line contains a press installed in a technological sequence, an automatic piece of a measuring beam, multi-stringed cutting machines with a common conveyor for feeding the beam, located perpendicular to the dryers, a mechanism for placing the products on the drying carts. The transport system is equipped with a conveyor for dispensing empty drying carriages and additional pushers of the formation of a train of drying carriages and pushers of step-by-step feeding of carts to multi-stringed cutting machines. 1 il.

Description

The invention relates to the building materials industry and can be used in brick factories during the removal and transportation of piece goods, such as bricks.

The aim of the invention is the expansion of technological capabilities.

The drawing schematically shows the proposed device.

The device comprises a carriage 1 and group grippers fixed thereto with pneumatic chambers 2 made of an elastic casing 3. The cavities of the pneumatic chambers are connected by pipelines 4 to the outlet of the pressure reducing valve 5, the supply of which is connected to the filter outlet 6. The supply of the filter 6 is connected to the outlet 7 of the two-position pneumoras pneumatic valve - limiter 8 with electropneumatic control. m. The second outlet 9 of the lateral distribution 8 is connected to the pneumatic distribution chamber 1 I, 10 I, the podode 12 of which is connected to the cavity of the internal chamber 2. The second inlet 13 pneumodistribution II is connected through the filter 14 to the outlet of the vacuum compressor 15, the inlet of which is connected to the outlet of the pneumatic distributor 11 .

The outlet of the vacuum compressor 15 is also connected via an additional valve 16 to the atmosphere. The control chamber 10 is via a reverse valve 17 and the throttle 18 is connected to the cavity of pneumatic chambers 2. The supply 19 of the pneumatic distributor 8 is connected to the atmosphere, and the outlet 20 is connected via an oil spout 21 to an air collector 22 connected to a source of compressed air through a reducer:

Valve 23. The valve 8 is controlled by electromagnets 24 and 25.

The device works as follows.

The vacuum compressor 15 is turned on. When the device is operated, compressed air is supplied to the air collector 22 through the pressure reducing valve 23 under a pressure of 0.4-0.6 MPa. Trolley 1 is suitable for removal of items. The solenoid 25 of the distributor 8 is turned on, the state of which is further maintained by compressed air. In this state, the distributor inlet 7 is connected to the control chamber 0. In connection with this, the Pneumatic distributor 11 is installed in the position in which its outlet is connected to the inlet 12. Thus, the inlet of the vacuum compressor 15 is connected to the cavity of the pneumatic chambers 2. The air from the pneumatic chambers is pumped out through the valve 16 in atmosphere. At the same time, part of the flow of air enriched with oil from the control chamber 10 through the check valve 17, and the throttle 18 goes to the inlet 12 of the distributor 11. The passage through the pneumatic distributor, this air lubricates it. A vacuum is created in the air bladder 2. The magnitude of this vacuum is determined by the performance of the vacuum compressor 15 and the setting of the throttles 18 and the valve .16. The elastic shells of 3 are drawn in, due to which it becomes possible to place the air shells into small gaps between the bricks.

When products are captured, a pulse electromagnet 24 is turned on, the on state of which is then maintained by compressed air. Compressed air, the passage through the oil sprayer 21, is enriched with the oil required for lubrication of the distributor 8. Compressed air through the filter 6 is supplied to the supply of the reducing valve 5. The passage through the filter 6, the air is cleaned of oil and water, which contributes to the durability of the elastic shells 3 of the pneumatic chambers 2 and eliminate the accumulation of oil B pnevmocamera. On reduction

valve 5 compressed air pressure is released to a value of 0.02 MPa. Under this pressure, air enters the pneumatic chamber 2, resulting in the capture of products. The compressed air cannot enter the cavity of pneumocamera 2 into the chamber 10 of the control valve AND due to the non-return valve 17. At the same time, the pneumatic distributor II is in the position corresponding to the mutation of the outlet of this distributor with supply 2. The vacuum compressor overtakes the air in a closed loop.

Next is the transfer of products. After transferring the products, a signal is issued to release air from the grippers. When this turns on the solenoid 25 of the distributor 8.

The valve 11 is installed in the position in which its outlet is connected to the inlet 12. The air is pumped out of the pneumatic chambers by the vacuum compressor and is discharged through the valve 16 to the atmosphere. This contributes to the rapid emptying of the pneumatic chambers, which makes it possible to load the products onto a moving platform.
