(54) DEVICE FOR CUTTING OF FIGURED GLASSES

(57) The invention relates to the glass industry and relates to equipment for cutting sheet glass with a copier of a complex configuration, namely for cutting shaped, for example, automobile glasses. The purpose of the invention is to improve the quality of the cut by stabilizing the efforts on the cutting roller. The device for cutting shaped glasses contains a cutting head 4, which is made in the form of a spindle assembly with a coaxially mounted hollow shaft 11 having a spring-loaded rod 27 with a tip 28 at one end and pto 29 at the other, pivotally mounted on the shaft -rake 23. The cutting head also has a carriage 17 placed on the rod with a cutting roller 21 and a pneumatic cylinder 7 with a gripper 8. A lever-rocker, 23 is installed with the ability to interact with the rod 27 of the cutting head and the fifth 29 spring-loaded rod. The tip 28 of the rod 27 is located in the gripper 8 of the pneumatic cylinder 7, and the hollow shaft 11 is mounted for rotation. The device allows to increase the service life of the cutting roller. 4 yl

The invention relates to the glass industry and relates to equipment that enables the cutting of sheet glass by a copier with a complex configuration, namely cutting curly, for example automotive, glass.

The purpose of the invention is to improve the quality of the cut by stabilizing the efforts on the cutting roller.

FIG. 1 shows the proposed device, top view; in fig. 2 - the same, in the initial position; in fig. 3 - the same at the time of the cut; in fig. 4 shows section A-A in FIG. 2

The device for cutting shaped glasses contains a table 1 with a soft lining 2

and a copier 3. which runs around the cutting head 4, mounted on a double-sided lever 5 and set in motion from the actuator 6 of the usual type. A pneumatic cylinder 7 with a gripper 8 is fixed above the table. The cutting head 4 consists of a housing 9 in which a hollow shaft 11 is coaxially fixed in rolling bearings 10, the upper part of which is threaded with a steering wheel 12 screwed into it, and the lower groove 13 in which a flange 14 of a stop sleeve 15 is provided, provided with a groove 16. A carriage 17 is fastened to the shaft 11, comprising a copy roller 18 through which the rod 19 passes, the upper part of which is fitted with tongues 20 and installed in the groove 16, and

the lower part is fixed to the cutting roller 21, the rollers 22, spring-loaded to the copier 3. On the flange 14 there is a lever-lever 23, one end 24 of which is hinged, and the other end 25 lies on the rod 19.

A spring-loaded rod 27 is installed inside the hollow shaft 11 in the spring 26, the upper part of which passes through the handwheel 12 and ends with the tip 28, and the lower part has an enlarged diameter — a pin 29 through which the stop pin passes, the ends of which are installed in the groove 13.

The device works as follows.

The glass 30 places the soft lining 2 of the table 1 under the copier 3 and installs the cutting head 4 attached to the two shoulders of the lever 5 at the starting point of the cut. A command is given to the pneumatic cylinder 7, which lowers the rod 19 onto the glass 30. This happens as follows: the gripper 8, the pneumatic cylinder 7 releases the tip 28 of the spring-loaded rod 27, which under the action of the elastic force of the spring 26 is lowered and presses on the rocker arm 23 and the thrust sleeve 15 which, in turn, displaces down the hollow shaft 11, presses the rod 19, lowering it until the cutting roller 21 contacts the surface of the glass 30, the drive 6 of the cutting head 4 is turned on and last, the copier 3 is covered on one side by copying R face 18, through which the rod 19 of the cutting roller 21 passes, and on the other roller 22, which allows the cutting roller 21 to apply a cutting line to the glass 30, the equidistant configuration of copier 3. When the cutting roller 21 moves, it is always oriented so that its plane is parallel the inner side wall of the copier 3 due to the fact that the hollow shaft 11, on which the carriage 17 is mounted with the rod 19 installed in it with the cutting roller 21, is placed in the housing 9 on rolling bearings 10, which allows the hollow shaft 11 to rotate during movement, the reference point cutting roll ik 21. The elastic force of the spring 26, and thus the force with which the cutting roller 21 presses against the glass 30, is adjusted by the wheel 12, which is screwed into the upper part of the hollow shaft 11, changing the length of the spring 26. The rod 19 of the cutting roller 21 has its upper the parts have flats 20 that prevent the rotation of the rod 19 and enable it to move only in the vertical direction.

At the final moment of cutting tip 28

spring rod 27 enters the gripper 8 of the pneumatic cylinder 7. A signal is given to the pneumatic cylinder 7, and it raises the spring-loaded rod 27 up, which occupies the initial position. During lifting, the movement of the spring-loaded stem 27 through the stop pin is transmitted to the entire cutting mechanism: the stop sleeve 15 rises, while the spring 26 is pressed and stops pressing on the rocker arm 23, which, in turn, relieves the pressure on the rod 19 of the cutting roller 21. In this case, the rod 19, which is engaged with the thrust sleeve 15, also

will begin to rise upward, withdrawing the cutting roller 21 from the glass 30. To obtain the next figured glass, the above described cycle is repeated.

The proposed device is compact,

it is convenient to use, it allows to obtain a high-quality cut by providing damping of the cutting roller and thereby stabilizing the force on it. In addition, it allows the cutting of glass of various configurations, while only the replacement of the copier is necessary.

Due to the fact that the cutting roller comes out of contact with the glass after the end of the cut, it requires a more rare replacement.
