(54) DEVICE FOR CUTTING GLASS TAPE

The invention relates to devices for cutting glass ribbon and can be used in the glass industry. A device is known for cutting glass tape, including a guide, made in the form of a profiled bar, serving as a core, a carriage with a cutting tool, an electric motor, made with the stator unrolled, the inductor ham mounted on the carriage, as well as the switches and the magnetic regulator for fixing the carriage l This device is complicated in design. . The closest to the predictable is a tape cutting device that includes a guide c. a carriage that is movably mounted on it, an electric motor, a directional direction switch, a limit switch, an elastic damper and a carriage field latch 2. A disadvantage of this device is the low quality of cutting of the obtained products. The purpose of the invention is to improve the quality of cutting glass ribbon,

ISS.iiIsi S The goal is achieved by the fact that a device for cutting glass ribbon containing a guide with a carriage movably mounted on it, an electric motor, a carriage stroke direction switch, a limit switch, an elastic damper and a carriage position lock are equipped with a control unit a pulse converter and a power amplifier, and the latch position of the carriage is emitted in the form of an electromagnet movably mounted by means of an elastic damper at one of the ends of the guide and connected to the output The power input is connected to the output of the pulse converter, and the input of the latter is connected to the switch of the direction of the carriage stroke and to the input of the control unit, the other input of which is connected to the limit switch, and the output of the control unit is connected to the carriage through the electric motor. Fig. 1 shows a graphical scheme for calculating the deviation of the lengths of the cut sheets from the specified dimensions depending on the coordinate of the carriage on the cross-cutting guide beam before the beginning of the cut, in Fig. 2

Pictured is a glass ribbon cutting device.

An inaccurate installation of the carriage to the initial position with a cutting roller on the guide beam 1, located at an angle si to the direction of movement of the glass ribbon 2 in accordance with the known ratio cbsd v / V, where V is the speed of movement of the glass ribbon; V - the speed of movement of the carriage, gives the error in the length of the cut sheets, which can be expressed in the form:

AO ..- ci.2xco6tt {P, -P, V-yV (P,).,

where P. and Pji are the carriage coordinates on the guide, defining the carriage installation zone in the initial position;

4, respectively, the magnitude of the displacement of the glass ribbon from the moment the carriage begins to move from the points with coordinates. . Tami P and Pj, up

the moment the cutting roller enters the point

R edges of glass ribbon.

The device for cutting glass ribbon contains a guide 1 mounted at an angle a to the direction of movement of the glass tape 2 (along arrow V) hours. On the guide 1 a carriage 3 with a cutting roller and a flag 4 are movably mounted along the rods 5, At one end of the guide 1, a switch is installed for the direction of movement of the carriage and the stop 7. At the opposite end of the guide 1 there are installed

the limit switch 8 and the electromagnetic lock 10 of the carriage on the elastic damper 9. As the sub 7 and the damper 9, for example, a pneumatic damper, a spring shock absorber, etc. can be used.

The electromagnetic lock 10 is connected to the output of the power amplifier 11, the input of which is connected to the output of the converter 12 pulses, which, in turn, is connected to the output of the switch 6 for the carriage stroke direction 3 and to one of the inputs of the carriage 3 control motor 14 A limit switch 8 is connected to another input of the control unit 13 in order to disable the engine 14 ,.

The device works as follows. .

The carriage with the cutting roller 3 is in the initial position at the electromagnet 10. At the command of the control unit 13, the engine 14 is turned on

and the carriage 3 with the cutting roller begins to slide along the holders 5, cutting the ribbon 2 of the glass. At the end of the forward stroke of the carriage, the flag 4 attached to the carriage 3 has 5 effects on the switch for the direction of the carriage stroke, which, through control unit 13, reverses the carriage's motor 14 and, through the transducer 12 pulse and power amplifier 11, turns on the electromagnet 10. The carriage 3 with a cutting roller, by inertia, hits the bolster 7, is thrown away by it and starts moving in the opposite direction. At the end of the reverse stroke checkbox

4 has an effect on the limit switch 8, which, through the control unit 13, turns off the carriage 14 moving the carriage with the cutting roller 3. The carriage moves by inertia until it contacts the electromagnet 10, is captured by it and held for the time necessary for the carriage 3 to completely stop

5 in the initial position. After that, the electromagnet is disconnected. The duration of the electromagnet 10 is determined by the duration of the pulse arriving at it through the power amplifier 11

0 with a converter of 12 pulses and

determined by the parameters of the latter.
