The invention relates to the building materials industry, in particular to the cutting of sheet glass, and can be used by factories producing technical, construction and other types of sheet glass,

The purpose of the invention is to simplify the design of the device and increase the accuracy. notches.

The drawing shows the proposed device, top view.

A device for transverse cutting of a moving glass ribbon contains a frame 1, made in the form of two supporting pedestals, on which guide 2 is fixedly mounted. Carriage 3 with cutting tool 4 is mounted for movement along guide 2. Axis 5 is fixed to carriage 3 A double-arm lever 6 is installed, a cutting tool 4 is fixed at one end (for example, a cutting roller on its axis), and on both sides of the other end of lever 6 are placed receivers 7 and 8 of the differential sensor of the synchronization unit, also closed captive to the carriage 3, the location of the lever arms 6 relative to the carriage 3 is selected so that the vibration displacement tool 4 in the direction of movement of the glass ribbon 9, the second lever arm 6 was reacted with receivers 7 and 8, a differential sensor,

In the process of simultaneously moving the belt 9 and the carriage. A notch 10 is applied to the glass.

The device has a variable speed carriage drive of known construction (not shown), for example, in the form of an adjustable electric motor with a chain transmission along the guide 2,

A synchronization unit (not shown) is a device for controlling the speed of a carriage movement drive with a cutting tool, for example, a standard complete electric drive.

The device works as follows

Using the synchronization unit, set the appropriate speed of movement of the carriage 3 along the guide 2, Hanpi-iMSp, at an angle between the guide 2 and the direction of movement of the belt 9 (shown by the arrow) equal to

60 °, the nominal speed of the carriage 3 is set at twice the speed of the belt 9,

The movement of the tool 4 by the carriage 3 at an angle to the direction of movement of the belt 9 can be viewed as two movements: along the belt and across it (when the latter an incision 10 is made), and the speeds of the belt and the tool move along it coincide. Under this condition, the applied notch 10 is perpendicular to the direction of movement of the belt 9. If the belt speed does not match the longitudinal component of the speed of the tool 4, for example, when the belt 9 speed increases, the belt deflects the tool 4 to the right, the lever arm 6 interacts with the receiver 8 of the differential synchronization unit sensor and the speed of movement of the carriage 3 increases. In this case, the tool 4 catches up the belt 9, and the lever arm 6 stops interacting with the receiver 8 of the differential sensor. With a further increase in the speed of the carriage 3, the tape lags behind the tool, deflects it on the axis 5 to the left, including the receiver 7, and the speed of the carriage decreases. Further, the operation of the device proceeds similarly about the writing until the termination of the notch 10,

Thus, during the operation of the device, the tool 4 continuously oscillates with respect to the perpendicular 10 in the direction of twofold of the tape, and there is a continuous adjustment of the position of the tool relative to this perpendicular. When the tool is deflected to the right, the speed of the carriage 3 decreases and the tool moves to the left and vice versa.

As a result, a sinusoidal curve is applied to the glass, the middle line of which coincides with the perpendicular 10 to the direction of the belt, regardless of the magnitude of the velocity of the latter and the oscillations of this velocity.

The amplitude of oscillations of the tool is determined by the distance between the receivers of the differential sensor and is set depending on the requirements imposed on the straightness of the edge of the glass sheets, for example, 0.5 mm long. Schshein tape 3600 mm.
