The invention relates to stone processing industry and can be used in the technique of automatic control of the modes of operation of stone cutting machines.

The purpose of the invention is to increase the accuracy of monitoring the life and reliability of the design.

Figs, 1 and 2 are schematic diagrams of the installation; Fig. 3 is an electrical sensor circuit.

The installation consists of a conveyor 1 with a drive, loading and unloading mechanisms with grippers (not shown), a sawing body 2 for sawing two ends of block 3, two contactors 4 sensors 4 and 5 of length

tilting mechanism 6, a multi-disc sawing body 7 for sawing the block 3, a mechanism 8 for distributing the saw block 3 to individual plates 9, a rotary table 10, a fringing body 11 and a control panel (not shown) with

The contact length sensor 4 controls two pushers 12 and 13 of spoilage with containers 14 and 15 of spoilage and is installed after the sawing body 2 and the other contact sensor of length 5 controls two pushrods of 16 and 17 scrapage of capacitance 18 and 19 of scrap. .

Contact sensors 4 and 5 are associated with scrap pushers 12, 13 and 16, 17, respectively, using time relays 20 and 21 and intermediate relays 22, 23 with 24, 25 and 26, 27 normally open and 28, 29 contacts normally open. Contact sensors 4 and 5 of length are made in the form of a spring-loaded hammer connected with fixed supports 30, 31 and mounted in pairs on both sides of their heads 32 with contacts 33, 34, and movable rollers 35 are mounted between the spring-loaded hammers and fixed supports 30, 31 and 36 seconds. Contact can be made with the surfaces of block 3 and tile 9, respectively.

The movable rollers 35 and 36 are connected to the springs of the fixed supports 30, 31 by means of rocker arms 37, 38. The scrap pushers 12, 13 and 16, 17 are made in the form of a metal rod with a flat KIM base passing through the electromagnetic saline drain 39, 40, which via time relay 20, 21,

the intermediate relays 22, 23 are connected with pairs of contacts 33, 34 which are installed in pairs on both sides of the hammer heads 32. Support rollers 41 and 42 are rigidly mounted on the opposite rollers 35 and 36 of the conveyor 1 side.

The rollers 41 and 42 are connected with the electrical contacts of the 43 sensors with stone and intermediate (not shown) „entered into the control panel of the device.

The installation works as follows.

Using the loading mechanism, the block 3 is laid on the conveyor 1 and the sawing body 2 is moved to saw the two ends of the block 3 of a certain size, after which one of its end surfaces contacts the movable roller 35 and the other end surface with support rollers 41.

To prevent the work of the corresponding pushers in the absence of controlled stones under the movable rollers 35 and 36, contacts 43 are triggered, which prevent the sensors 4 and 5 from closing.

If negative error J (width of the block is less than the set)

The contact head 32 of the contact length sensor 4 advances under the action of a spring and the contact 33 closes the circuit, the 20V15meny relay triggers for the time required to move the unit 3 to the rejection zone 12, after the required delay, the intermediate relay 22 actuates the pusher 12 rejects, which moves the defective unit 3 into the capacitance 14 and then immediately disconnect the intermediate relay 22 with their normally closed contacts 28. The circuit changes to the initial state.

With a positive error (the geometrical dimensions of the block more than installed), the hammer head 32 of the contact sensor 4 is advanced under the action of the block and the contact 34 closes the circuit, the time relay 21 triggers for the time required to move the block 3 to the reject pusher 13 after the required the time delay is triggered by an intermediate relay 23 and by its contact 27 turns on a reject pusher 13, which moves the rejected

unit 3 into the capacitance 15 and then immediately disconnects the intermediate relay 23 with its normally closed contacts 29. The system switches to the initial position. Unstained blocks 3, moving along the conveyor 1, pass through the tilting mechanism 6 with the help of the sawing body 7, are sawn into plates 9. Then, using the mechanism 8, they are installed individually on the conveyor and passed through the turntable 10. The turning body 11 carries out the plate canton on certain dimensions, after which one of its edged surfaces acts on the length sensors 5 through the movable roller 36, and the opposite surface moves along the base support rollers 42.

 With a negative error. (the plate length is shorter than the installed one) The hammer head 32 of the contact length sensor 5 advances under the spring opening and the contact 33 clamps the circuit, the time relay 20 is triggered for the time required to move the plate 9 to the defective work pusher 16, after the required delay time the intermediate the relay 20 and its contact 26 turn on the reject pusher 16, which moves the rejected plate 9 into the tank 18 and then immediately disconnects the intermediate relay 22 with its normally closed contacts 28. The system goes to the original Assumption.

With a positive error (the plate length is longer than the installed one), the head 32 of the contact length sensor hammer 5 advances under the action of the plate and the contact 34 closes the circuit, the time relay 21 is activated for the time required to move the plate 9 to the work zone of the reject pusher 17, after the required delay time the intermediate relay 23 and its contact 27 turns on the reject pusher 17, which moves the rejected plate 9 into the tank 19, and then immediately turns off the intermediate turnip 23 with its norm-. the contacts are closed. 29. The system returns to the initial state. The unblocked plates 9, moving along the conveyor 1, arrive at the finished product site.

To create a continuous operation of the installation, the conveyor 1 is made of two parts, adding one of them. parts after the multi-sawing unit 7 different speed.
