SU408916A1 - DEVICE FOR CUTTING SHEET GLASS ON VERTICAL EXTRACTING MACHINE - Google Patents

Description

one

The invention relates to a glass machinery industry H can be used in glass factories, where sheet glass is produced both by boat and without a bezelnochny method.

A device for cutting sheet glass on a vertical cutting machine is known, which contains speed sensors, a counter mounted on the directions, their nodarechnik and slitting glass with drives, an angle control of the cross section guide, and a thickness gauge.

However, the presence of bulky transport means, mechanisms for stopping, fixation reduces the reliability of the line and requires large production areas. The presence of obliquity in glass sheets produced on the formats produced by a vertical tool reduces the quality and color, the yield of the product is.

The purpose of the invention is to improve the quality of the finished product. For this, the speed sensors are connected through a counter to the drive of the crosscutter and to the tilt angle adjuster of the crosscutting guide, the thickness gauge connected to the counter, and the speed sensors are made with slats and mounted along the edges of the glass ribbon.

The drawing shows the proposed device.

It contains speed sensors 1 with strips 2 and a counter 3. The drive 4 is kinematically connected with a cross-cutter 5 moving along the array 6, and serves to change the speed of the non-shifter cutter. The tilt angle controller 7 serves to change the tilt angle of the cross-cutting guide 6, and the sensor 8 electrically connected to the time relay 9 and the actuator 10 -

For removal from the tape, glass cutters // longitudinal cuts are mounted on rails 12. Thickness gauge 13 allows controlling the modes of cutting the tape of glass in dependence on its thickness.

The proposed device works as follows. The speed sensors 1, directly in contact with the end of the tape through the strips 2, moving together with the tape up, monitor the speed of its drawing.

In the proposed device there is no slippage between the contacting elements of the sensors and the surface of the tape. From sensors 1 controlling the speed of the glass ribbon, signals are sent to counter 3, the difference in which it registers the speed of movement of the tape and sends a command to the drive 4. The latter, receiving the command, moves the cutter 5 along the guide 6 at a speed proportional to the speed of movement of the tape glass When the cutter is moved to the extreme position, sensor 5 is triggered and, via time relay 9, a signal is sent to the drive W of the retraction of cutters 11 installed on the guide 12 longitudinal in: racks that go through the tape to the tape; longitudinal cutting is continued for a given number of cuts. If the sensors 1 detect a change in the tape speed, then the counter 3 receives a command to the actuator 4 to change the speed of movement of the chaser 5.

Another option for matching the speed of the glass ribbon with the movement of the cutter is provided as follows. When the tape draw speed changes according to the difference of signals from sensors 1, the counter 3 sends a command to the controller 7, which changes the angle of the guide 6 in one direction or the other depending on the increase or decrease in the tape speed.

The device can automatically adjust the speed of the tape to control its thickness, since, depending on the thickness of the tape, the drawing speed also changes. In this case, the glass ribbon thickness gauge 13 sends a signal to one of the inputs of the counter 3, from which a command is sent to the actuator 4, which changes the speed of movement of the clipper 5, or to the regulator 7, which changes the angle of rotation of the guide 6.

The proposed device can work with one m sensor. At the same time, the signal from the sensor is fed to one of the inputs of the counter 3, which sends a command to the actuator 4 for changing the speed of movement of the clipper 5, or to the regulator 7, which changes the angle of the movement guide 6 of this clipper.

The proposed device allows for the transverse cutting of the glass ribbon both in the forward and in the reverse course of the cutter 5. This is achieved by changing the angle of the guide 6.
