(54) DEVICE FOR INSTALLATION OF CUTTING ORGAN FOR STONE-CARVE AND 1-OPERATING MACHINE

one

The invention relates to the building materials industry, in particular to stone-cutting and stone-processing machines.

A device is known for mounting a cutting unit of stone-cutting machines to a stone size comprising an electric motor, a switch, an element of time, start-up units, a braking and stopping of an electric motor 71. The disadvantage of this device is low accuracy, since when setting the size of the stone, the element of time is an indirect factor. The accuracy of the device operation is reduced due to errors due to the intrinsic response time of the time element, the spread of timing parameters, and the inconsistency of the rotation speed of the electric motors.

The closest to the technical essence is the device for installing the cutting body of stone cutting. STONE SIZE

and a stone processing machine for a camp size containing a control unit, a start-up, braking and stopping unit, a counter and an actuator connected to the output of the start-up, braking and stopping unit, the input of which is connected to the control unit 2.

The disadvantage of this device is the lack of accuracy and convenience in

10, since stopping the cutting member without first reducing the speed, even with sufficiently effective braking, is often not within the tolerances of the product.

15 In addition, the intervals between the pulses coming from the motor speed sensor do not always unambiguously determine the linear movement of the cutting member and do not necessarily correspond to the multiplicity of the product size and the tolerance for this size.

 The purpose of the invention is to improve the accuracy of the installation. This is achieved by the device for installing the cutting unit of stone-cutting and stone-processing machines on the size of the stone containing the control unit, the start-up, braking and stopping unit, the counter, and the executive mechanism connected to the output of the starting-up, braking and stopping unit, the input of which is connected to the control unit is equipped with a sum torus, a unit for setting a zero indicator, a unit for shifting speed, a program setting unit for size, and a unit for measuring the size consisting of a series-connected compensator and sensor, moreover, the program setting block of size is connected to one of the inputs of the adder, the other input of which is connected to one counter output, the other output of which is connected via an indicator to one output of the zero setting block, the other output of which is connected to one input of the counter, another input that is connected through the block size measurement with the actuator output, the actuator is connected to the output of the speed control unit, the input of which is connected through the control unit to the input of the installation unit zero, and the input of the control unit in laziness is connected to the output of the adder. The drawing shows this device. The device contains a program setting block 1, a pulse counter 2, an adder 3, a control block 4, a block 5 for starting, braking and stopping the actuator, a block 6 for switching the actuator to reduced speed, an actuator 7, an indicator 8, a block 9 for setting zero, a size measurement unit 10 consisting of a sensor II and a compensator 12. The device operates as follows. Before the start of work, the signals proportional to the size at which the actuator should be transferred to a reduced speed, and to a given final stone size, are set at the output of block 1 of the programmed dimensioning program. From the start-up, braking and stopping unit 5, the actuator is actuated. The tool member moves to the cut point. The counter 2 counts the pulses generated by the 9 sensor II of the size measurement unit 10. At the same time, the compensator 12, also included in the size measurement unit 10, ensures the coordination of the operation of the actuator 7 with the Hbtti linear movement of the tool, the minimum size tolerance, the multiplicity of the specified size and the division value of the pulse counter. When moving the working body to the place of cut at the output of the pulse counter 2, a signal is established that is proportional to the actual distance traveled. The signal, proportional to the difference between the set and actually reached values, taken from the adder 3, enters the control unit 4, which, when reaching the first signal embedded in block 1 of the programmed dimensioning, affects the block 6, transfers the actuator 7 to a reduced speed, and then, when the specified final size is reached, it locks and disconnects it via block 5. During the period of movement of the working body, indicator 8 continuously records, with a given division price, the actual achieved size. When the specified final size is reached and the actuator 7 is disconnected from the control unit 4, the zero setting indicator through the installation unit 9 enters the spent size indicator 8 and the pulse counter 2 signal returns the circuit to the initial one, i.e. zero, position. To set the indicator 8 to zero and the pulse counter 2 can also be applied to the zero setting unit 9. The use of this device will facilitate the work of the operator of stone-cutting and stone-processing machines and will allow To iiHocTb to increase the size of the stone being cut, which will lead to an increase in the quality of construction and facing works.
