(54) УСТРОЙСТВО УПРАВЛЕНИЯ РЕЗКОЙ ГЛИНЯНОГО БРУСА(54) DEVICE MANAGEMENT OF CUTTING CLAY BAR

II

Изобретение относитс к оборудованию дл производства .строительных материалов и может быть использовано при созданий и модернизации автоматов дл резки,глин ного бруса.The invention relates to equipment for the production of building materials and can be used in the creation and modernization of cutting machines, clay bars.

Известно устройство управлени автоматов дл резки кирпича с механизмами отрезки бруса и резки его на кирпичи, содержаш ,ее логический элемент И, датчик поступлени бруса, блок управлени и датчик крайнего положени 1.A control device is known for brick cutting machines with mechanisms for cutting logs and cutting it into bricks containing its logical element I, a sensor for arriving of a bar, a control unit and an extreme position sensor 1.

Однако это устройство не обеспечивает управление режущей рамкой механизма отрезки бруса.However, this device does not provide control of the cutting frame of the mechanism pieces of the beam.

Наиболее близким к предлагаемому по технической сушности вл етс устройство управлени резкой глин ного бруса, содержащее каретку, механизм отрезки с приводом , который соединен с со6тветств5 ющими пускател ми, и датчик положени каретки 2..Closest to the proposed technical dryness is a control unit for cutting clay cladding containing a carriage, a cut-off mechanism with an actuator that is connected to the corresponding actuators, and a carriage position sensor 2 ..

Однако в известном устройстве дл подвода проводов к датчику между рамой и кареткой подвешиваетс гибкий кабель. Наличие подвижного датчика и гибкого токопровода усложн ет конструкцию и снижа ет надежность работы.However, in a known device for supplying wires to the sensor, a flexible cable is suspended between the frame and the carriage. The presence of a movable sensor and a flexible conductor complicates the design and reduces reliability.

Цель изобретени - повышение надежности работы.The purpose of the invention is to increase the reliability of work.

Эта цель достигаетс тем, что устройство управлени резкой- глин ного бруса, содержащее каретку, механизм отрезкис приводом , который соединен с соответствующими пускател ми, и датчик положени каретки , снабжено делителем частоты, двум инверторами и двум логическими элементами И, причем датчик полохсени каретки подключен ко входу делител частоты и ко fO входу первого инвертора, выход которого соединен с одним из входов элементов И, выходы которых подключены к соответствующим пускател м, выход делител частоты подключен ко входу второго инвертора и к другому входу первого элемента И, а выход инвертора соедин ен с другим входом второго элемента И.This goal is achieved by the fact that the control unit of the cutting clay bar containing the carriage, the cut-off mechanism with the drive, which is connected to the corresponding actuators, and the carriage position sensor, is equipped with a frequency divider, two inverters and two logic elements, And to the input of the frequency divider and to the fO input of the first inverter, the output of which is connected to one of the inputs of the elements AND, whose outputs are connected to the corresponding starters, the output of the frequency divider is connected to the input of orogo inverter and the other input of the first AND gate and an inverter output coupled to another input ene second member I.

На чертеже схематично представлено устройство управлени автоматом.The drawing schematically shows the control device of the machine.

Claims

The clay bar 1 is molded by a press 2. A brick cutting machine is made in the type of carriage 3 located above the conveyor 4. The carriage is equipped with a flap 5 and a bar 6 cutting mechanism with an actuator 7. The carriage has an 8 position carriage sensor connected to frequency divider 9 and through the inverter 10 to the inputs of the two elements 11 and 12. The input of the element 11 is connected to the output of the divider 9 through the second inverter 13, and the input of the circuit 12 directly. The output of the element 11 is connected to the starter 14, which controls the movement of the drive 7, cut timber upwards, and the output of the element 12 is connected to the starter 15, which controls the movement of the drive 8 downwards. The valve 5 is provided with a roller 16 adapted to interact with the cam 17 located on the frame 18. The proposed device operates as follows. The clay beam 1, continuously molded by the press 2, moves along the conveyor 4 and rests against the shutter 5. The carriage 3 moves off. At the output of sensor 8, a signal appears which, via inverter 10, is fed to the inputs of both elements 11 and 12 and to the input of frequency divider 9. From the output of the frequency divider, the signal is fed to the second input of element 12. Starter 15 turns on and drive 7 bar 6, providing the last move down and the length of the measured bar. Upon further movement of the carriage roller 16 acts on the copier 17. The flap 5 leans back and the cut bar is removed by the conveyor 4. The carriage 6 under the influence of a counterweight or a separate drive (not shown in the drawing) returns to its original position. The clay bar formed by the press again acts on the flap 5, and the carriage moves off. As for the first time, signals from sensor 8 are fed to elements 11 and 12 and divider 9. Since the frequency divider passes signals through once, there will be no signal at its output and the second input, but the signal is received at the output of inverter 13 and the second input element 11. The starter 14 and the drive 7 of the mechanism for cutting the beam 6, which ensures the latter to move upwards and to the length of the measuring beam, is turned on. Similarly, the next timber will be cut down. Then the cycle repeats. The proposed device provides control of the automaton without using sensors of the position of the piece mechanism and the flexible conductor of the carriage, which allows simplifying the design of the automaton and increasing its reliability.
