(54) AUTOMATIC MACHINE FOR CUTTING BRICK

I,. /:

- The invention relates to equipment for the production of building materials and can be used in the development of daky and the modernization of automatic cutting machines for clay bars.

A machine for cutting a bar of plastic material is known, which consists of a forming press, a conveyor driven, mecanism of string cutting. The disadvantage of this machine is the high pa6oTfei mechanism, since cutting is performed on one bar. The accuracy of cutting timber on these machines is small.

1 Avesten brick cutting machine .2, containing a press molding, a dimensional bar cutting mechanism, a multi-string cutting mechanism, including an excellent conveyor with a preg-frame, a receiving frame and a pusher drive, a control unit for receiving drives, porter travers, sensors for the entry of a bar and the extreme position of the body.

The disadvantage of this automaton is that to stop the truck driver and issue a command to the cutting device: the sensor uses a sensor about the approach of the beam to the stop, which is installed at the end of the trans. porter. In the case of a large capacity, the conveyor speed must be large enough; the bar, moving away to the support, will be crushed and its geometrical dimensions will change, which will result in smaller sizes and reduced dimensions.

The purpose of the invention is to improve the accuracy of cutting. The capped cell is achieved by the fact that in the cutting machine

Claims (2)

5 bricks containing a press molding, a measuring bar cut mechanism, a multi-string cutting mechanism including a tfieme conveyor with a drive, a cutting frame and a pusher drive, & IOK drive control of the receiving conveyor and pusher, bar entry sensors to the extreme position of the pusher, fitted with a trigger element And, and in front of the cutting frame there is a beam entry sensor, one of which soda is connected to one trigger input, the other input of which is connected to the extreme position sensor of the pusher And the other output beam arrival sensor coupled to one input of the AND gate, the other input of which is connected to the output flip-flop, and the output of the AND gate is connected to the drive pusher and the input control unit, which soybeans union of output drive receiving transporte- pa. . The brick cutting machine is shown in the drawing and contains the mechanism 1 pieces of the measuring bar and the mechanism of the cutting machine, made in the form of pushers 2 with drive 3 and cutting frame 4, receiving conveyor 5 with drive 6, control unit 7, sensor growth bar .8, trigger 9, logic element AND 1O, sensor 11 of the extreme position of the pusher, measuring bar 12 and molding 13, the machine works as follows. The plastic bar 12 is molded with a press 13. From the gluing tape 13 which is continuously molded with a press, the measuring bar 12 is cut off by multi conveyor 5 is transmitted to the multi-string cutting mechanism. In front of the pusher 2, the beam acts on the sensor 8, the signal of which switches the trigger. The inputs to the circuit 10 previously had a zero trigger signal and a single signal from the inverse output of sensor 8, according to which its output was a zero signal. When acting on sensor 8, the signal from the rover output of this sensor becomes zero, and the signal from the trigger becomes single, as a result of which And the zero signal continues to remain at the circuit output And. After the passage of the beam for the sensor 8 (the position of the beam is shown in the drawing by a dotted line), 74 unit signals appear on both inputs of the circuit AND The output signal from this circuit is fed to the control unit 7, which reduces the speed and turns off the drive 6 of the receiving conveyor 5, and to the input of the drive 3 2. The measuring bar is pushed by the pusher 2 through the cutting frame 4, and is cut into individual bricks. At the end of the stroke, the pusher 2 acts on Sensor 11, the signal of which switches the trigger. The pusher returns to its original position. Then the cycle repeats. Claims of the invention — A brick cutting machine comprising a forming press, a dimensional bar cutting mechanism, a multi-string cutting mechanism comprising a receiving conveyor with a drive, a cutting frame and a pusher drive, a control unit for receiving conveyor and pusher drives, sensors for entering the bar and the extreme position of the pusher differing the fact that, in order to improve the accuracy of cutting, the machine is also equipped with an AND logic element, and an input beam sensor is installed in front of the cutting frame, one of whose outlets is connected to one named by the trigger input, another input of which is connected to the extreme position sensor of the pusher, another output of the beam entrance sensor is connected to one of the inputs of the logic element And, another input of which is connected to the output of the trigger, and the output of the logic element And is connected to the drive of the pusher and input a control unit, the output of which is connected to the conveyor drive.
