(54) INSTALLATION FOR CUTTING GLASS TAPES ON FORMATS

one

The invention relates to glass engineering and can be used in factories producing sheet glass.

Lo main auth.St. No. 596554, there is a known installation for cutting glass tapes into formats comprising conveyor conveyors, a sucker with suction cups and cutting heads for longitudinal and transverse, a carriage, with the liner and cutting heads for lateral cutting of RZs fixed on it.

A disadvantage of the known installation is the impossibility of an automated fracture, since in carrying out longitudinal and transverse cutting of sheets into formats on one side of the sheet, the latter does not have sufficient strength, which leads to spontaneous breaking of sheets along the incisions during transportation along the rolls.

The purpose of the inventions is to provide an automated break.

This goal is achieved in that the installation for cutting the glass ribbon is provided with pressure rolls mounted for vertical movement over the cutting heads that are placed with the possibility of vertical movement under the glass ribbon.

FIG. 1 shows schematically an installation, a plan view; in fig. 2, in view A in FIG. one; in fig. 3 - cut. BB in FIG. one.

. Above the roller table I, a mechanism 2 pieces of sheets is installed, the transferor 3 connects the roller table 1 to the roll table 4, built into the automated line 5 breaking the sheets into formats and packing formats. The glass sheets on the roller table 1 move in the direction indicated by arrow B.

The slider 3 includes a lifting frame 6 with supports 7 and a carriage 38 with vacuum suction cups 9 installed with the possibility of moving transversely relative to the conveyor 1 along guides 10 mounted on beams 11 connected by points 12 with struts J3. The power cylinder 14 and the wedge 15 form the mechanism for lifting the frame 6. The drive of the carriage 8 is made in the form of the gearmotor 16 and the chain gear J7. On the carriage B with the possibility of adjusting movement along the guide 18, the cutting heads 19 of the transverse cutting are fixed. The roller carved table 4 includes a section of the roller table 20, the axes of the rolls of which are parallel to the axis of the roller table 1 and driven from into rotation by means of a reversible gearmotor 21 and chain gear 22, a baseman 23, longitudinal cutting cuts 24, located under the transport plane with the possibility of installation movement along the guides 25., and clamping valgsi 26, installed with the possibility of installation movement in the vertical plane. The glass sheet 27, which enters Line 5, contains transverse 28 and longitudinal 29 notches, respectively located on the upper and lower surfaces of the sheet. The installation works as follows. Sheets of glass that are moved along the roller conveyor by mechanism 2 are cut off, which are then broken by a fragments roll. separated and accelerated distributed by pipeline with a given schagom. When the sheet enters the zone of the transfer unit 3, it turns on the cylinder 14, and with wedges 15 lifts the frame 6. At the same time, the glass sheet is removed from the roll table 1, pressed against and sucked by the suction cups 9. Next, the frame 6 is lowered, which makes it possible to skip the next sheet on the roller table I, and the sheet 27 is transferred by carriage 8 to the table of the roller table 20. After the vacuum is turned off and the sheet is laid on the roller table 20, the base 8 is turned on. , cutting heads 19 apply transverse cuts 28, then gearmotor 21 is turned on, and sheet 27 is transferred to line 5. In the process of moving the sheet, cutting heads 24 apply longitudinal cuts 29 to its bottom surface. e rolls 26 interfere spin sheet cutting heads 24 provided thereby cutting quality. The location of the marginal cuts on the bottom surface of the sheet ensures its sufficient strength in the longitudinal direction when moving the rolls of line 5 along the rolls, and randomly breaking along the transverse cuts 28 during transportation is practically impossible, since in the immediate vicinity of the starting position, these cuts are forced, then the strips containing only longitudinal notches are transported. Constructive execution of the installation provides the possibility of using it in lines with automated operations of breaking sheets into formats and packaging of formats. The invention The installation for cutting glass ribbon on formats av.st. No. 596554, in contrast to the fact that, in order to provide an automated break, it is equipped with pressure rolls mounted for vertical movement over cutting heads that are placed for vertical movement under the glass ribbon.
